SUMMARY RISK FACTORS

Investing in the Company's shares involves numerous risks, including the risks described in "Item 3.D—Risk Factors" of this Annual Report on
Form  20-F.  Below  are  some  of  the  principal  risks,  any  one  of  which  could  materially  adversely  affect  the  Company's  business,  financial
condition, results of operations, and prospects:

• Biopharmaceutical  development  involves  a  high  degree  of  uncertainty  and  most  of  the  product  candidates  are  in  early  stages  of

development.

•

•

•

•

•

•

•

•

The scientific evidence to support the feasibility of developing product candidates is both preliminary and limited.

The Company intends to develop several of its product candidates in combination with other therapies, which exposes it to additional
risks.

The Company is heavily dependent on the success of its current clinical-stage product candidates

The Company may not be successful in its efforts to develop additional products that receive regulatory approval and are successfully
commercialized.

The Company may encounter substantial delays in its clinical studies or may be unable to conduct its clinical studies on the timelines the
Company expects.

The Company's product candidates in development may cause undesirable side effects or have other properties that could halt or delay
their clinical development, prevent their regulatory approval, limit their commercialization or result in other negative consequences.

The Company faces substantial competition from companies with significantly greater resources and experience.

The  regulatory  processes  that  will  govern  the  approval  of  the  Company’s  product  candidates  are  complex  and  changes  in  regulatory
requirements could result in delays or discontinuation of development or unexpected costs in obtaining regulatory approval.

• Any  of  the  Company's  product  candidates,  if  approved  and  commercialized,  may  fail  to  achieve  market  acceptance  by  physicians,

patients, third-party payors or the medical community to a degree that is necessary for commercial success.

• A fast track, breakthrough therapy or other designation by the FDA, or equivalent in other territories, may not actually lead to a faster

development.

•

•

•

•

•

The Company has no manufacturing capabilities and relies on third-party manufacturers for its product candidates.

The Company relies on third parties to supply key materials used in its research and development, to provide services to the Company
and to assist with clinical studies.

The Company depends upon its existing collaboration partners, AstraZeneca, Sanofi and other third parties, and may depend upon future
collaboration partners to commit to the research, development, manufacturing and marketing of its drugs.

The  late-stage  development  and  marketing  of  the  Company’s  product  candidates  may  partially  depend  on  its  ability  to  establish
collaborations with major biopharmaceutical companies.

The Company has incurred and may in the future incur significant operational losses related to its research and development activities.

9

•

•

•

•

•

•

•

•

•

•

The Company may need to raise additional funding to complete the development and any commercialization of its product candidates,
which may not be available on acceptable terms, or at all, and failure to obtain this necessary capital when needed may force it to delay,
limit or terminate its product development efforts or other operations.

If the Company does not achieve its product development or commercialization objectives in the timeframes it expects, the Company
may not receive product revenue or milestone or royalty payments, and it may not be able to conduct its operations as planned.

The  revenues  generated  from  the  Company’s  collaboration  and  license  agreements  have  contributed  and  are  expected  to  contribute  a
large portion of its revenue for the foreseeable future.

The Company benefits from tax credits in France that could be reduced or eliminated.

The current state of the world financial market and current economic conditions could have a material adverse impact on the Company's
business, financial condition and results of operations.

The Company's business could be affected by natural disaster, such as wildfire, and this could be exacerbated by climate change.

The Company’s ability to compete may be adversely affected if the Company does not adequately obtain, maintain, protect and enforce
its intellectual property or proprietary rights, or if the scope of intellectual property protection the Company obtains is not sufficiently
broad.

The Company’s patents could be found invalid or unenforceable if challenged, and it may not be able to protect its intellectual property.

The dual listing of the Company’s ordinary shares and the ADSs may adversely affect the liquidity and value of the ADSs.

The Company may be affected by political, social, legal and economic instability, civil unrest, war and other geopolitical tension, such as
the ongoing military conflict between Russia and Ukraine and economic sanctions related thereto.

D.    Risk Factors

The Company's business faces significant risks. You should carefully consider all of the information set forth in this Annual Report and in the
other filings with the SEC, including the following risk factors which Innate faces and which are faced by its industry. The Company's business,
financial  condition  or  results  of  operations  could  be  materially  adversely  affected  by  any  of  these  risks.  This  report  also  contains  forward-
looking statements that involve risks and uncertainties. Innate's results could materially differ from those anticipated in these forward-looking
statements, as a result of certain factors, including the risks described below and elsewhere in this Annual Report and its other SEC filings. See
“Special Note Regarding Forward-Looking Statements” above.

Risks Related to the Development of the Product Candidates

Biopharmaceutical development involves a high degree of uncertainty and most of the product candidates are in early stages of development,
which makes it difficult to evaluate the current business and future prospects and may increase the risk of your investment.

Innate Pharma is a global, clinical stage oncology-focused biotech company developing a portfolio of product candidates, some of which Innate
is co-developing, in the early stages of clinical development and preclinical programs.

A key element of Innate's strategy is to mature and expand its portfolio of proprietary and partnered product candidates to address unmet medical
needs in immuno-oncology. Although Innate's research and development efforts to date have resulted in a pipeline of product candidates, all of
its product candidates require additional development, regulatory review and approvals, substantial investment, access to sufficient commercial
manufacturing capacity and significant marketing efforts before they can be commercialized and before Innate can generate any revenue from
product sales or royalties. If the Company or its collaboration partners are unable to successfully develop and market these product candidates,
its business, prospects, financial condition and results of operations may be adversely affected.

Aside from Innate's commercial experience with Lumoxiti that ended in December 2020, its operations to date have been limited to developing
its product candidates and undertaking preclinical studies and clinical studies of its product candidates, including monalizumab and IPH5201,
through  its  partnership  with  AstraZeneca;  IPH6401/SAR'514  through  its  partnership  with  Sanofi;  and  lacutamab,  IPH5301,  IPH6501  and
IPH4502,  its  most  advanced  product  candidates,  currently  in  the  clinical  stage. The  success  in  development  of  its  current  and  future  product
candidates by the Company or its collaborators will depend on many factors, including:

•

•

•

•

•

obtaining  positive  results  in  clinical  trials,  including  by  demonstrating  efficacy,  safety  and  durability  of  effect  of  such  product
candidates;

completing  preclinical  studies  and  receiving  regulatory  approvals  or  clearance  for  conducting  clinical  trials  for  its  preclinical
programs;

receiving and maintaining approvals for commercialization of such product candidates from regulatory authorities;

manufacturing or overseeing the manufacturing of its product candidates in acceptable quantities and at an acceptable cost;

negotiating favorable terms in any collaboration, licensing or other arrangements into which the Company may enter, and performing
its obligations pursuant to such arrangements;

11

•

•

•

maintaining,  protecting,  enforcing  and  expanding  its  portfolio  of  intellectual  property  rights,  including  patents,  trade  secrets  and
know-how;

avoiding and defending against third-party interference, infringement or other intellectual property claims; and

maintaining  and  growing  an  organization  of  scientists,  medical  professionals  and  marketing,  distribution  and  sales  personnel  and
executives who can develop its product candidates and commercialize any approved products.

In addition, if the Company is unable to reduce its dependence on its current clinical and preclinical product candidates, either by in-licensing or
acquiring  new  product  candidates,  developing  its  other  product  candidates  or  discovering  new  product  candidates,  the  Company  may  be
similarly adversely affected.

The scientific evidence to support the feasibility of developing product candidates is both preliminary and limited.

Innate Pharma's innovative approach to immuno-oncology aims to activate both the innate and adaptive immune systems against abnormal or
cancerous cells and restore the body’s ability to disrupt their proliferation, potentially leading to durable responses in patients. This approach is
focused on developing checkpoint inhibitors, tumor-targeting antibodies and antibodies that affect the tumor microenvironment, and several of
the product candidates rely on novel mechanisms of action and on innovative formats for which the Company has limited scientific evidence and
preclinical and clinical data.

The  Company  may  not  ultimately  be  able  to  provide  the  FDA,  European  Medicines  Agency  (EMA)  or  other  regulatory  authorities  with
substantial clinical evidence to support a claim of efficacy and durability of response to enable the applicable regulators to approve its product
candidates  for  any  indication. This  may  occur  because  later  clinical  studies  fail  to  reproduce  favorable  data  obtained  in  earlier  clinical  trials,
because the applicable regulator disagrees with how the Company interprets the data from these clinical trials or because the applicable regulator
does not accept these therapeutic effects as valid endpoints in pivotal clinical trials that are sufficient to grant marketing approval. Additionally,
because  product  candidates  in  later  stages  of  clinical  trials  may  fail  to  show  the  desired  safety  and  efficacy  traits  despite  having  progressed
through preclinical studies and earlier clinical studies, its collaborators in earlier stages of clinical trials may eventually choose to discontinue
later stage studies. For example, in 2022, AstraZeneca informed Innate Pharma of the discontinuation of the Interlink-1 Phase 3 clinical study
assessing monalizumab in combination with cetuximab in patients with recurrent or metastatic squamous cell carcinoma of the head and neck, as
this combination did not meet a pre-defined threshold for efficacy.

In  addition  to  the  safety  and  efficacy  traits  of  any  product  candidate,  clinical  study  failures  may  result  from  a  multitude  of  factors,  including
flaws in study design, dose selection, placebo effect and patient enrollment criteria. A number of companies in the pharmaceutical industry have
suffered significant setbacks in advanced clinical studies due to lack of efficacy or adverse safety profiles, notwithstanding promising results in
earlier studies, and it is possible that the Company will as well. Based upon negative or inconclusive results, the Company or its collaborators
may decide, or regulators may require, the Company to conduct additional clinical studies or preclinical studies. In addition, data obtained from
studies are susceptible to varying interpretations, and regulators may not interpret the Company's data as favorably as the Company does, which
may delay, limit or prevent regulatory approval.

The Company will also need to demonstrate that its product candidates are safe and well tolerated. The Company does not have significant data
on possible harmful long-term effects of its product candidates and does not expect to have this data in the near future. As a result, its ability to
generate clinical safety

12

and efficacy data sufficient to support submission of a marketing application or commercialization of its product candidates is uncertain and is
subject to significant risk.

The  Company  intends  to  develop  several  of  its  product  candidates  in  combination  with  other  therapies,  which  exposes  the  Company  to
additional risks.

The  Company  is  currently  developing  monalizumab,  lacutamab,  IPH5201  and  IPH5301,  and  may  develop  other  product  candidates,  in
combination with one or more currently approved cancer therapies. Specifically, AstraZeneca is currently evaluating monalizumab in ongoing
Phase 1, 2 and 3 trials in combination with durvalumab, an anti-PD-L1 immune checkpoint inhibitor. Lacutamab is also currently evaluated in
combination with chemotherapy GEMOX (gemcitabine in combination with oxaliplatin) in patients with PTCL (Peripheral T Cell Lymphoma).
In  addition,  IPH5201  is  also  currently  under  clinical  investigation,  in  a  Phase  2  study  in  combination  with  durvalumab  and  chemotherapy.
Finally, IPH5301 is currently under clinical investigation in a Phase 1 study in combination with a chemotherapy, paclitaxel and trastuzumab.
Patients  may  not  be  able  to  tolerate  the  Company's  product  candidates  in  combination  with  other  therapies,  and  preliminary  clinical  results
indicate  that  monalizumab,  for  example,  has  no  meaningful  clinical  activity  as  a  monotherapy.  Even  if  any  product  candidate  the  Company
develops were to receive marketing approval or be commercialized for use in combination with other existing therapies, the Company would
continue to be subject to the risks that the FDA, EMA or other comparable foreign regulatory authorities could revoke approval of the therapy
used in combination with its product candidate or that safety, efficacy, manufacturing or supply issues could arise with these existing therapies.
Combination  therapies  are  commonly  used  for  the  treatment  of  cancer,  and  the  Company  would  be  subject  to  similar  risks  if  the  Company
develops any of its product candidates for use in combination with other therapies or for indications other than cancer. This could result in its
own products, if approved, being removed from the market or being less successful commercially.

The Company may also evaluate any of its current and future product candidates in combination with one or more other cancer therapies that
have  not  yet  been  approved  for  marketing  by  the  FDA,  EMA  or  comparable  foreign  regulatory  authorities. The  Company  will  not  be  able  to
market and sell monalizumab, lacutamab, IPH5201 or IPH5301 or any other product candidate the Company develops in combination with any
such unapproved cancer therapies that do not ultimately obtain marketing approval.

If  the  FDA,  EMA  or  other  comparable  foreign  regulatory  authorities  do  not  approve,  revoke  their  approval  of,  or  if  safety,  efficacy,
manufacturing  or  supply  issues  arise  with,  the  products  or  product  candidates  the  Company  chooses  to  evaluate  in  combination  with
monalizumab,  lacutamab,  IPH5201,  IPH5301  or  any  other  product  candidate  the  Company  develops,  the  Company  may  be  unable  to  obtain
approval of or market monalizumab or any other such product candidate the Company develops.

The  Company  is  heavily  dependent  on  the  success  of  its  current  clinical-stage  product  candidates,  and  it  cannot  be  certain  that  it  or  its
collaborators will be able to obtain regulatory approval for, or successfully commercialize, these product candidates.

The  Company's  business  and  future  success  depend  on  receiving  regulatory  approval  for,  and  the  commercial  success  of,  its  proprietary  and
partnered  product  candidates.  The  Company  has  agreements  with  AstraZeneca  with  respect  to  the  advanced  development,  clinical  study
collaboration and potential future registration and marketing of several of its product candidates, including monalizumab and IPH5201, and with
Sanofi for the research and development of IPH6401/SAR’514, IPH62 and of another program in solid tumors. Its near-term prospects depend
heavily on AstraZeneca’s successful clinical development and commercialization of monalizumab, as well as the successful clinical development
of its other product candidates. The clinical success of these product candidates will depend on a number of factors, including the ability and
willingness  of AstraZeneca,  Sanofi  and  the  Company's  other  collaborators  to  complete  ongoing  clinical  studies  respectively  for  monalizumab
and IPH6401/SAR'514

13

or other partnered assets, the ability to complete the clinical trials for which the Company is responsible and the safety, tolerability and efficacy
of its product candidates.

The  Company  may  not  be  successful  in  its  efforts  to  develop  additional  products  that  receive  regulatory  approval  and  are  successfully
commercialized.

The  development  of  a  product  candidate  is  a  long,  costly  and  uncertain  process,  aimed  at  demonstrating  the  therapeutic  benefit  of  a  product
candidate that competes with existing products or those being developed. There is no guarantee that the Company or its collaborators will be able
to demonstrate a sufficient degree of clinical efficacy or safety of one or more of its proprietary or licensed product candidates in order to gain
regulatory approval or to become commercially viable. The degree of uncertainty associated with clinical development and the risks associated
with developing new product candidates may make it difficult to evaluate its current business and its future prospects.

The  Company  intends  to  continue  to  develop  its  product  candidates  that  are  currently  in  clinical  trials,  including  monalizumab,  lacutamab,
IPH5201, IPH5301, IPH6401/SAR’514, IPH6501 and IPH4502. Monalizumab is currently being investigated in multiple Phase 1, Phase 2 and
Phase 3 clinical studies under a co-development agreement with AstraZeneca. Lacutamab is currently being investigated in an open-label, multi-
cohort Phase 2 clinical study in CTCL and in a Phase 2 in PTCL. IPH5201 is currently being investigated in an open-label Phase 2 clinical study.
IPH5301  is  currently  being  investigated  in  a  Phase  1  clinical  study  sponsored  by  the  Institut  Paoli-Calmettes.  IPH6101/SAR'579  is  currently
investigated in a Phase 1/2 clinical study, sponsored by Sanofi. The continued Sanofi-led Phase 1/2 study of IPH6401/SAR’514 for the treatment
of  patients  with  relapsed  or  refractory  multiple  myeloma  will  be  terminated  early  and  will  now  be  refocused  to  pursue  development  in
autoimmune indications. IPH6501 is currently investigated in a first-in-human, Phase 1/2 study in B-Cell non-Hodgkin lymphoma indication.
IPH4502 is currently investigated in a first-in-human, Phase 1 study in patients with advanced solid tumors known to express Nectin-4.

While the Company believes that it will eventually have the in-house capabilities to complete the development and/or support the development
by a partner of monalizumab, lacutamab, IPH5201, IPH5301, IPH6401/SAR'514, IPH6501 and IPH4502, the Company has not yet completed
the clinical studies for these or other product candidates, and there can be no assurance that these or other product candidates will gain regulatory
approval or become commercially viable.

Delays in the preclinical development of a product candidate could lead to delays in initiating clinical development. A failure in the preclinical
development of a product candidate could lead to abandoning its development. Further delays or failures at the various clinical stages for a given
indication  could  result  in  delay  or  halt  the  development  of  the  product  candidate  in  such  indication  or  in  other  indications.  Moreover,
disappointing results during the initial Phases of development are often not a sufficient basis for deciding whether or not to continue a project. At
these early stages, sample sizes, the duration of studies and the parameters examined may not be sufficient to enable a definitive conclusion to be
drawn, in which case further investigations are required. Conversely, promising results during the initial phases, and even after advanced clinical
studies have been conducted, do not guarantee that a product candidate or an approved drug will be successfully approved and commercialized.

The risks related to the failure of a product candidate’s development are highly related to the stage of maturity of the product candidate. Given
the relatively early stage of the product candidates in the pipeline, there is a substantial risk that some or all of the product candidates will not
obtain  regulatory  approval  or  be  commercialized,  which  would  have  an  adverse  impact  on  the  Company's  business,  prospects,  financial
condition and results of operations.

14

The Company may not be successful in its efforts to identify, discover or develop additional product candidates, including those based on its
innovative ANKET  technology.

®

The Company is seeking to develop a broad and innovative pipeline of product candidates in addition to monalizumab, lacutamab, IPH5201,
IPH5301, IPH6101/SAR'579, IPH6401/SAR’514, IPH6501 and IPH4502. The Company may not be successful in identifying additional product
candidates for clinical development for a number of reasons. For example, its research methodology may be unsuccessful in identifying potential
product  candidates  or  the  potential  product  candidates  the  Company  identifies  may  have  harmful  side  effects,  lack  of  efficacy  or  other
characteristics that make them unmarketable or unlikely to receive regulatory approval.

®

Moreover, some of its innovative pipeline of product candidates are based on its innovative ANKET  platform, which is not yet approved. The
ANKET   platform  consists  of  two  different  formats,  tri-specific  and  tetra-specific  antibodies.  A  multi-specific  is  also  being  developed  in
partnership  with  Sanofi  (IPH62).  The  Company  is  developing  IPH6501,  a  tetra-specific  proprietary  antibody.  Even  if  the  Company  aims  at
maintaining a diversified pipeline, the use of an innovative technology represents additional risks in the product candidate development.

®

Research programs to pursue the development of the product candidates for additional indications and to identify new product candidates and
disease targets require substantial technical, financial and human resources. The Company's research programs may initially show promise in
identifying potential indications or product candidates, yet fail to yield results for clinical development for a number of reasons, including:

•

•

•

the research methodology used may not be successful in identifying potential indications or product candidates;

potential  product  candidates  and/or  its ANKET   technology  may,  after  further  study,  be  shown  to  have  harmful  adverse  effects  or
other characteristics that indicate they are unlikely to be effective drugs; or

®

it  may  take  greater  human  and  financial  resources  to  identify  additional  therapeutic  opportunities  for  its  product  candidates  or  to
develop suitable potential product candidates through internal research programs than the Company will possess, thereby limiting its
ability to diversify and expand its product portfolio.

Accordingly,  there  can  be  no  assurance  that  the  Company  will  ever  be  able  to  identify  additional  indications  for  its  product  candidates  or  to
identify and develop new product candidates through internal research programs. The Company may focus its efforts and resources on potential
product candidates or other potential programs that ultimately prove to be unsuccessful.

The Company may encounter substantial delays in its clinical studies or may be unable to conduct its clinical studies on the timelines the
Company expects.

Clinical testing is expensive, time consuming and subject to uncertainty. The Company cannot guarantee that any clinical trials will be conducted
as planned or completed on schedule, if at all. A failure of one or more clinical studies can occur at any stage of testing, and its future clinical
studies may not be successful. Events that may prevent successful or timely completion of clinical development include:

•

•

inability to generate sufficient preclinical, toxicology or other in vivo or in vitro data to support the initiation of clinical trials;

delays or failure in reaching a consensus with regulatory agencies on clinical study design;

15

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

delays in reaching agreement on acceptable terms with prospective Contract Research Organisations (CROs) and investigational sites,
the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and investigational sites;

imposition  of  a  temporary  or  permanent  clinical  hold  by  regulatory  agencies,  including  as  a  result  of  a  new  safety  finding  that
presents  unreasonable  risk  to  clinical  study  participants,  a  negative  finding  from  an  inspection  of  its  clinical  trial  operations  or
investigational sites, developments in trials conducted by competitors for related technology that raise regulators’ concerns about risk
to patients of the technology broadly or if a regulatory body finds that the investigational protocol or plan is clearly deficient to meet
its stated objectives. For example, in October 2023, the lacutamab IND was put on partial hold by the FDA following the death of one
patient from hemophagocytic lymphohistiocytosis (HLH). The FDA then lifted this partial hold based on their review of the fatal case
which Innate, together with a steering committee of independent experts, determined to be related to aggressive disease progression
and lacutamab unrelated;

delays in recruiting suitable patients to participate in its clinical studies;

difficulty collaborating with patient groups and investigators;

failure by the Company, its CROs or other third parties, including its collaborators, to adhere to clinical study requirements;

delays in having patients complete participation in a clinical study or return for post-treatment follow-up;

patients withdrawing from a clinical study;

occurrence of adverse events associated with a product candidate that are viewed to outweigh its potential benefits;

changes in regulatory requirements and guidance that require amending or submitting new clinical trial protocols;

regulatory feedback requiring the Company to amend the protocols of ongoing clinical studies in response to safety considerations, as
the Company has previously been required to;

changes in the standard of care on which a clinical development plan was based, which may require new or additional clinical trials;

the cost of clinical studies of its product candidates being greater than the Company anticipates;

clinical studies of its product candidates producing negative or inconclusive results, which may result in the Company deciding, or
regulators requiring the Company, to conduct additional clinical studies or abandon product development programs;

transfer  of  manufacturing  processes  to  larger-scale  facilities  operated  by  either  a  contract  manufacturing  organization  (CMO)  and
delays or failure by its CMOs or the Company to make any necessary changes to such manufacturing process; and

batch recalls, recalls of manufactured product candidates or delays in manufacturing, testing, releasing, validating, or importing or
exporting sufficient stable quantities of its product candidates for use in clinical studies or the inability to do any of the foregoing.

Any inability to successfully complete preclinical and clinical development could result in additional costs to the Company or impair its ability
to generate revenue. In addition, if the Company makes

16

manufacturing or formulation changes to its product candidates, it may be required to or it may elect to conduct additional studies to bridge its
modified  product  candidates  to  earlier  versions.  Clinical  study  delays  could  also  shorten  any  periods  during  which  its  products  have  patent
protection and may allow its competitors to bring products to market before the Company does, which could impair its ability to successfully
commercialize its product candidates and may harm its business and results of operations.

The Company depends on enrollment of patients in its clinical studies for its product candidates.

Successful and timely completion of clinical studies will require that the Company or its subcontractors enroll a sufficient number of suitable
patients. Clinical studies may be subject to delays as a result of patient enrollment taking longer than anticipated or patient withdrawal. Patient
enrollment  depends  on  many  factors,  including  the  size  and  nature  of  the  patient  population,  which  is  typically  limited  for  rare  or  orphan
diseases,  making  the  enrollment  more  difficult,  eligibility  criteria  for  the  study,  the  proximity  of  patients  to  clinical  sites,  the  design  of  the
clinical  protocol,  the  availability  of  competing  clinical  studies,  the  availability  of  new  drugs  approved  for  the  indication  the  clinical  study  is
investigating  and  clinicians’  and  patients’  perceptions  as  to  the  potential  advantages  of  the  drug  being  studied  in  relation  to  other  available
therapies.  For  example,  the  Company  is  developing  lacutamab  for  the  treatment  of  cutaneous T  cell  lymphoma  (CTCL).  CTCL  is  an  orphan
disease,  which  means  that  the  potential  patient  population  is  limited.  In  addition,  there  are  several  other  product  candidates  potentially  in
development for the indications for which the Company is developing product candidates, and the Company may compete for patients with the
sponsors of trials for those drugs. These factors may make it difficult for the Company to enroll enough patients to complete its clinical studies in
a timely and cost-effective manner. Delays in the completion of any clinical study of any of its product candidates will increase its costs, slow
down  its  product  candidate  development  and  approval  process  and  delay  or  potentially  jeopardize  its  ability  to  commence  product  sales  and
generate revenue. In addition, some of the factors that cause, or lead to, a delay in the commencement or completion of clinical studies may also
ultimately lead to the inability to obtain regulatory approval of its product candidates.

The Company's product candidates in development may cause undesirable side effects or have other properties that could halt or delay their
clinical development, prevent their regulatory approval, limit their commercialization or result in other negative consequences.

Use of the Company's product candidates in development could be associated with side effects or adverse events, which can vary in severity and
in  frequency.  Undesirable  side  effects  or  unacceptable  toxicities  caused  by  its  products  or  product  candidates  could  cause  the  Company  or
regulatory authorities to interrupt, delay or halt clinical studies. The FDA or European regulatory authorities could delay or deny approval of the
Company's product candidates for any or all targeted indications and negative side effects could result in a more restrictive label for any drug
that  is  approved.  Side  effects  such  as  toxicity  or  other  safety  issues  associated  with  the  use  of  the  Company's  product  candidates  could  also
require it or its collaborators to perform additional studies or halt development of product candidates or sale of approved products.

Treatment-related  side  effects  could  also  affect  patient  recruitment  or  the  ability  of  enrolled  subjects  to  complete  the  trial,  or  could  result  in
potential  product  liability  claims.  In  addition,  these  side  effects  may  not  be  appropriately  or  timely  recognized  or  managed  by  the  treating
medical  staff,  as  toxicities  resulting  from  immunotherapy  are  not  normally  encountered  in  the  general  patient  population  and  by  medical
personnel. Inadequate training in recognizing or managing the potential side effects of its product candidates could result in adverse effects to
patients, including death. Any of these occurrences may have an adverse impact on the Company's business, prospects, financial condition and
results of operations.

17

The Company faces substantial competition from companies with significantly greater resources and experience.

The  biotechnology  and  pharmaceutical  market,  and  notably  the  immuno-oncology  field,  is  characterized  by  rapidly  advancing  technologies,
products protected by intellectual property rights and intense competition and is subject to significant and rapid change as researchers learn more
about diseases and develop new technologies and treatments. The Company faces potential competition from many different sources, including
major pharmaceutical companies, specialty pharmaceutical and biotechnology companies, academic institutions and governmental agencies and
public  and  private  research  institutions.  For  example,  other  companies  are  developing  ADCs  targeting  Nectin-4,  such  as  Eli  Lilly,  Astellas
Pharma  and  Corbus  Pharmaceuticals. Any  product  candidates  that  the  Company  or  its  collaborators  successfully  develop  will  compete  with
existing therapies and new therapies that may become available in the future. If competing products are marketed before Innate's products, or at
lower prices, or cover a wider therapeutic spectrum, or if they prove to be more effective or better tolerated, the Company's business, prospects,
financial condition and results of operations could be affected.

Many of the Company's competitors who are developing immuno-oncology and anti-cancer therapies have considerably greater resources and
experience  in  research,  drug  development,  finance,  manufacturing,  marketing,  technology  and  personnel  and  access  to  patients  for  clinical
studies  than  the  Company  does.  In  particular,  large  pharmaceutical  companies  have  substantially  more  experience  than  the  Company  does  in
conducting  clinical  studies  and  obtaining  regulatory  authorizations.  Mergers  and  acquisitions  in  the  pharmaceutical,  biotechnology  and
diagnostic industries may result in even more resources being concentrated among a smaller number of the Company's competitors. Smaller or
early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established
companies. These competitors are also likely to compete with the Company to recruit and retain scientific and management personnel, acquire
rights for promising product candidates and other complementary technologies, establish clinical investigational sites and patient registration for
clinical studies and acquire technologies complementary to, or necessary for, its programs, as well as to enter into collaborations with partners
who have access to innovative technologies. If the Company cannot successfully compete with new or existing products, its marketing and sales
will suffer and the Company may never be profitable. Should any of these risks materialize, Innate's business, prospects, financial condition and
results of operations may be adversely affected.

The Company cannot guarantee that its product candidates will:

•

•

•

•

obtain regulatory authorizations or become commercially available before those of its competitors;

remain  competitive  in  the  face  of  other  products  developed  by  its  competitors,  which  may  prove  to  be  safer,  more  effective,  have
fewer or less severe side effects, be more convenient, have a broader label, have more robust intellectual property protection or be
less expensive;

remain  competitive  in  the  face  of  products  of  competitors  that  are  more  efficient  in  their  manufacturing  or  more  effective  in  their
marketing; and

not become obsolete or unprofitable due to technological progress or other therapies developed by its competitors.

In  addition,  while  any  future  product  candidate  that  is  approved  may  compete  with  many  existing  drugs  or  other  therapies,  to  the  extent  it  is
solely used in combination with these therapies, the Company's product candidates will not be competitive with such therapies, but any sales of
such products could be limited to sales of the combination therapy. In this case, the Company would be exposed to the same competitive risks as
the product used in combination with its product, such as a product that is marketed before the

18

combination  therapy,  has  lower  prices,  covers  a  wider  therapeutic  spectrum  or  proves  to  be  more  effective  or  better  tolerated.  For  additional
information regarding competition to its business see “Item 4. Information on the Company—B. Business Overview—Competition.”

Risks Related to Regulatory Approval and Marketing of Innate's Product Candidates and Legal Compliance Matters

Even if the Company completes the necessary preclinical and clinical studies, the marketing approval process is expensive, time-consuming
and uncertain and may prevent the Company from obtaining approvals for the commercialization of some or all of its product candidates. If
the Company is not able to obtain, or if there are delays in obtaining, required regulatory approvals, in particular in the United States or the
European Union, the Company will not be able to commercialize its product candidates, and its ability to generate revenue will be materially
impaired.

The research and development of pharmaceutical products is governed by complex regulatory requirements. The regulatory agencies that oversee
these requirements have the authority to permit the commencement of clinical studies or to temporarily or permanently halt a study. They are
entitled  to  request  additional  clinical  data  before  authorizing  the  commencement  or  resumption  of  a  study,  which  could  result  in  delays  or
changes to the product development plan. As the Company advances its product candidates, the Company will be required to consult with these
regulatory  agencies  and  comply  with  all  applicable  guidelines,  rules  and  regulations.  If  the  Company  fails  to  do  so,  the  Company  may  be
required  to  delay  or  discontinue  development  of  its  product  candidates.  Delay  or  failure  to  obtain,  or  unexpected  costs  in  obtaining,  the
regulatory approval necessary to bring a potential product to market could decrease its ability to generate sufficient product revenue to maintain
its business.

The  clinical  studies  of  Innate's  product  candidates,  the  manufacturing  and  the  marketing  of  its  product  candidates  are  and  will  be,  subject  to
regulation by numerous government authorities in the United States, in the European Union and in other countries where the Company intends to
test and, if approved, market any product candidate. Before obtaining regulatory approvals for the commercial sale of any product candidate, the
Company  must  demonstrate,  with  substantial  evidence  gathered  in  well-controlled  clinical  trials,  and,  with  respect  to  approval  in  the  United
States, to the satisfaction of the FDA, with respect to approval in the European Union, to the satisfaction of the EMA or, with respect to approval
in  other  countries,  similar  regulatory  authorities  in  those  countries,  that  the  product  candidate  is  safe  and  effective  for  use  in  each  target
indication.

The Company has never submitted a product candidate for marketing approval in the United States, in the European Union or elsewhere.

In the United States, the Company expects that the requisite regulatory submission to seek marketing authorization for its product candidates will
be a Biologic License Application (BLA) and the competent regulatory authority is the FDA. In the European Union, the requisite approval is a
Marketing Authorization (MA), which for products developed by the means of antibody-based therapeutics, gene or cell therapy products as well
as  tissue  engineered  products,  is  issued  through  a  centralized  procedure  involving  the  EMA  (see  “Item  4.  Information  on  the  Company—B.
Business Overview—Regulation”). Satisfaction of these and other regulatory requirements is costly, time consuming, uncertain and subject to
unanticipated delays. Failure to comply with the applicable requirements at any time during the product development process, approval process
or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include, for example, the FDA’s refusal
to approve pending applications, withdrawal of an approval, a clinical hold, untitled or warning letters, product recalls or withdrawals from the
market, product seizures, total or partial suspension of production or distribution

19

injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.

Data from preclinical and clinical studies are likely to give rise to different interpretations, which could delay regulatory authorization, restrict
the  scope  of  any  such  authorization  or  force  Innate  to  repeat  trials  in  order  to  meet  the  requirements  of  the  various  regulators.  Regulatory
requirements and processes vary widely among countries, and the Company may be unable to obtain authorization within each relevant country
in a timely manner. Regulatory authorities may prevent Innate from starting clinical studies or continuing clinical development if the data were
not produced according to applicable regulations or if they consider that the balance between the expected benefits of the product and its possible
risks is not sufficient to justify the trial.

Despite the Company's efforts, its product candidates may not:

•

•

•

offer improvement over existing, comparable products;

be proven safe and effective in clinical trials; or

meet applicable regulatory standards.

This  process  can  take  many  years  and  may  include  post-marketing  studies  and  surveillance,  which  will  require  the  expenditure  of  substantial
resources  beyond  the  existing  cash  on  hand.  Of  the  large  number  of  drugs  in  development  globally,  only  a  small  percentage  successfully
complete the regulatory approval process and not all approved drugs are successfully commercialized. Delay or failure to obtain, or unexpected
costs in obtaining, the regulatory approval necessary for the Company or its partners to bring a potential product candidate to market could have
a material adverse effect on its business, prospects, financial condition and results of operations.

The regulatory processes that will govern the approval of Innate's product candidates are complex and changes in regulatory requirements
could result in delays or discontinuation of development or unexpected costs in obtaining regulatory approval.

The Company's product candidates are based on new approaches and/or technologies that are constantly evolving and have not been extensively
tested  on  humans. The  applicable  regulatory  requirements  vary  between  jurisdictions  and  are  also  complex,  potentially  difficult  to  apply  and
subject to significant modifications. Modifications to regulations during the course of clinical development and regulatory review may lead to
delays or the refusal of authorization.

In Europe, the United States and other countries, regulations can potentially:

•

•

•

significantly delay or increase the cost of development, testing, manufacturing and marketing of Innate's products;

limit the indications for which the Company will be authorized to market its products; and

impose  new,  more  stringent  requirements,  suspend  marketing  authorizations  or  request  the  suspension  of  clinical  trials  or  the
marketing  of  its  products  if  unexpected  results  are  obtained  during  trials  performed  by  other  researchers  on  products  similar  to  its
products.

Marketing  authorization  in  one  jurisdiction  does  not  ensure  marketing  authorization  in  another,  but  a  failure  or  delay  in  obtaining  marketing
authorization in one jurisdiction may have a negative effect on the regulatory process in others. Failure to obtain marketing authorization in other
countries or any delay or setback in obtaining such approval would impair the Company's ability to develop additional markets for its product
candidates. This would reduce Innate's target market and limit the full commercial potential of its product or product candidates. Should any of
these risks materialize, this could harm its business.

20

Innate  Pharma's  failure  to  obtain  marketing  approval  in  jurisdictions  other  than  the  United  States  and  Europe  would  prevent  Innate's
product candidates from being marketed in these other jurisdictions, and any approval the Company is granted for its product candidates in
the United States and Europe would not assure approval of product candidates in other jurisdictions.

In  order  to  market  and  sell  its  other  product  candidates  in  jurisdictions  other  than  the  United  States  and  Europe,  the  Company  must  obtain
separate marketing approvals and comply with numerous and varying regulatory requirements. The approval process varies among countries and
can  involve  additional  testing. The  time  required  to  obtain  approval  may  differ  from  that  required  to  obtain  FDA  approval  or  approvals  from
regulatory authorities in the European Union. The regulatory approval process outside the United States and Europe generally includes all of the
risks  associated  with  obtaining  FDA  approval  or  approvals  from  regulatory  authorities  in  the  European  Union.  In  addition,  some  countries
outside  the  United  States  and  Europe  require  approval  of  the  sales  price  of  a  product  before  it  can  be  marketed.  In  many  countries,  separate
procedures must be followed to obtain reimbursement, and a product may not be approved for sale in the country until it is also approved for
reimbursement. The Company may not obtain marketing, pricing or reimbursement approvals outside the United States and Europe on a timely
basis, if at all. Approval by the FDA or regulatory authorities in the European Union does not ensure approval by regulatory authorities in other
countries or jurisdictions, and approval by one regulatory authority outside the United States and Europe does not ensure approval by regulatory
authorities in other countries or jurisdictions or by the FDA or regulatory authorities in the European Union. The Company may not be able to
file  for  marketing  approvals  and  may  not  receive  necessary  approvals  to  commercialize  its  products  in  any  market.  Marketing  approvals  in
countries  outside  the  United  States  and  Europe  do  not  ensure  pricing  approvals  in  those  countries  or  in  any  other  countries,  and  marketing
approvals and pricing approvals do not ensure that reimbursement will be obtained.

Side  effects  that  appear  following  the  launch  of  a  drug  on  the  market  may  result  in  the  product  being  taken  off  the  market  or  additional
warnings being added to the label despite having obtained all regulatory approvals.

A  drug’s  launch  in  the  market  may  expose  a  large  number  of  patients  to  potential  risks  associated  with  treatment  with  a  new  pharmaceutical
product. Certain side effects, which may not have been identified during clinical trials, can subsequently appear. For these reasons, regulatory
agencies require companies to implement post-approval monitoring. Depending on the occurrence of serious undesirable effects, the agencies
may require that the Company or a collaboration partner take a drug off the market temporarily or permanently, even if it is effective and has
obtained  all  the  necessary  marketing  authorizations.  Such  an  action  would  negatively  impair  the  Company's  ability  to  generate  revenue  from
such  product  and  could  more  generally  negatively  affect  its  ability  to  develop,  obtain  regulatory  approval  for,  and  commercialize  its  other
product candidates and its reputation generally, each of which could have a material adverse effect on its business and results of operations. In
addition, if the product candidates the Company develops receive marketing authorization and the Company or others identify undesirable side
effects  caused  by  any  product  after  the  approval,  a  number  of  potentially  significant  negative  consequences  could  result,  including  that
regulatory authorities may require the addition of labeling statements, such as a “boxed” warning or a contraindication, the Company may be
required to create a medication guide outlining the risks of such side effects for distribution to patients and its reputation may suffer.

Any  product  candidate  for  which  the  Company  obtains  marketing  approval  will  be  subject  to  strict  enforcement  of  post-marketing
requirements  and  the  Company  could  be  subject  to  substantial  penalties,  including  withdrawal  of  its  product  from  the  market,  if  the
Company fails to comply with all

21

regulatory requirements or if the Company experiences unanticipated problems with its product and product candidates, when and if any of
them are approved.

Any product candidate for which the Company obtains marketing approval will be subject to continual requirements of and review by the FDA,
EMA  and  other  regulatory  authorities,  including  requirements  relating  to  manufacturing  processes,  post-approval  clinical  data,  labeling,
advertising and promotional activities for such product. These requirements include, but are not limited to, restrictions governing promotion of
an approved product, submissions of safety and other post-marketing information and reports, registration and listing requirements, current good
manufacturing  practice  (cGMP),  requirements  relating  to  manufacturing,  quality  control,  quality  assurance  and  corresponding  maintenance  of
records and documents and requirements regarding the distribution of samples to physicians and recordkeeping. In addition, even if marketing
approval  of  a  product  candidate  is  granted,  the  approval  may  be  subject  to  limitations  on  the  indicated  uses  for  which  the  product  may  be
marketed, restrictions for specified age groups, warnings, precautions or contraindications or to the conditions of approval.

The  FDA  and  other  federal  and  state  agencies,  including  the  U.S.  Department  of  Justice  (DOJ),  closely  regulate  compliance  with  all
requirements governing prescription products, including requirements pertaining to marketing and promotion of products in accordance with the
provisions of the approved labeling and manufacturing of products in accordance with cGMP requirements. The FDA and DOJ impose stringent
restrictions  on  manufacturers’  communications  regarding  off-label  use,  and  if  the  Company  does  not  market  its  products  for  their  approved
indications,  the  Company  may  be  subject  to  enforcement  action  for  off-label  marketing.  Prescription  products  may  be  promoted  only  for  the
approved  indications  and  in  accordance  with  the  provisions  of  the  approved  label.  However,  companies  may  also  share  truthful  and  not
misleading  information  that  is  otherwise  consistent  with  the  labeling.  Violations  of  such  requirements  may  lead  to  investigations  alleging
violations of the Food, Drug and Cosmetic Act and other statutes, including the False Claims Act and other federal and state health care fraud
and abuse laws, as well as state consumer protection laws. The Company's failure to comply with all regulatory requirements, and later discovery
of previously unknown adverse events or other problems with its products, manufacturers or manufacturing processes, may yield various results,
including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

litigation involving patients taking its products;

restrictions on such products, manufacturers or manufacturing processes;

restrictions on the labeling or marketing of a product;

restrictions on product distribution or use;

requirements to conduct post-marketing studies or clinical trials;

warning letters or untitled letters;

withdrawal of the products from the market;

refusal to approve pending applications or supplements to approved applications that the Company submits;

recall of products;

fines, restitution or disgorgement of profits or revenues;

suspension or withdrawal of marketing approvals;

damage to relationships with any potential collaborators;

unfavorable press coverage and damage to its reputation;

refusal to permit the import or export of its products;

22

•

•

product seizure; or

injunctions or the imposition of civil or criminal penalties.

Non-compliance by the Company or any future collaborator with the FDA, EMA or other regulatory requirements regarding safety monitoring or
pharmacovigilance,  and  with  requirements  related  to  the  development  of  products  for  the  pediatric  population,  can  also  result  in  significant
financial penalties. Similarly, failure to comply with regulatory requirements regarding the protection of personal information can also lead to
significant penalties and sanctions.

Coverage and reimbursement may be limited or unavailable in certain market segments for the Company's product candidates, if approved,
which could make it difficult for the Company to sell its product candidates profitably.

Successful sales of its product candidates, if approved, will depend, in part, on the availability of adequate coverage and reimbursement from
government authorities and third-party payors, such as private health insurers and health maintenance organizations. Patients who are provided
medical treatment for their conditions generally rely on third-party payors to reimburse all or part of the costs associated with their treatment.
Adequate coverage and reimbursement from governmental healthcare programs, such as Medicare and Medicaid in the United States or Social
Security in France, and commercial payors are critical to new product acceptance.

Government  authorities  and  third-party  payors,  such  as  private  health  insurers  and  health  maintenance  organizations,  decide  which  drugs  and
treatments they will cover and the amount of reimbursement. Coverage and reimbursement by a third-party payor may depend upon a number of
factors, including the third-party payor’s determination that use of a product is:

•

•

•

•

•

a covered benefit under its health plan;

safe, effective and medically necessary;

appropriate for the specific patient;

cost-effective; and

neither experimental nor investigational.

Policies  for  coverage  and  reimbursement  for  products  vary  among  third-party  payors.  No  uniform  policy  of  coverage  and  reimbursement  for
products  exists  among  third-party  payors,  and  third-party  payors  are  increasingly  challenging  the  price,  examining  the  medical  necessity  and
reviewing  the  cost-effectiveness  of  approved  drugs  and  medical  services,  in  addition  to  questioning  their  safety  and  efficacy.  As  a  result,
obtaining  coverage  and  reimbursement  approval  of  a  product  from  a  government  or  other  third-party  payor  is  a  time-consuming  and  costly
process that could require the Company or its partners to provide to each payor supporting scientific, clinical and cost-effectiveness data for the
use of its products on a payor-by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. Coverage decisions
may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives
are already available or subsequently become available. Even if the Company obtains coverage for a given product, the resulting reimbursement
payment rates might not be adequate for it to achieve or sustain profitability or may require co-payments that patients find unacceptably high.
Additionally, third-party payors may not cover, or provide adequate reimbursement for, long-term follow-up evaluations required following the
use of the Company's product candidates or approved products.

Because its product candidates represent new approaches to the treatment of cancer and, accordingly, may have a higher cost than conventional
therapies and may require long-term follow-up evaluations, the risk

23

that  coverage  and  reimbursement  rates  may  be  inadequate  for  the  Company  to  achieve  profitability  may  be  elevated.  There  are  currently  a
limited number of immunotherapy products that are designed to treat cancer on the market and, accordingly, there is less experience or precedent
for the reimbursement of such treatments by governmental entities or third-party payors.

Government restrictions on pricing and reimbursement and other healthcare cost-containment initiatives may negatively affect its ability to
generate revenues for its product candidates for which the Company obtains regulatory approval.

Government authorities and other third-party payors are developing increasingly sophisticated methods of controlling healthcare costs, including
by  limiting  coverage  and  the  amount  of  reimbursement  for  particular  medications.  Increasingly,  third-party  payors  are  requiring  that
pharmaceutical and biotechnology companies provide them with predetermined discounts from list prices as a condition of coverage, are using
restrictive  formularies  and  preferred  drug  lists  to  leverage  greater  discounts  in  competitive  classes  and  are  challenging  the  prices  charged  for
medical products.

In the United States, the European Union and other foreign jurisdictions, there have been a number of legislative and regulatory changes to the
healthcare system that could affect the Company's or its partners’ ability to sell its products profitably.

On March 23, 2010, President Obama signed into law the Affordable Care Act (ACA), which includes a number of healthcare reform provisions.
The ACA, among other things, imposed a significant annual fee on companies that manufacture or import branded prescription drug products;
addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that
are inhaled, infused, instilled, implanted or injected; increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug
Rebate  Program  and  extended  the  rebate  program  to  individuals  enrolled  in  Medicaid  managed  care  organizations;  and  established  a  new
Medicare  Part  D  coverage  gap  discount  program,  in  which  manufacturers  were  required  to  agree  to  offer  50%  point-of-sale  discounts  off
negotiated  prices  of  applicable  brand  drugs  to  eligible  beneficiaries  during  their  coverage  gap  period,  as  a  condition  for  the  manufacturer’s
outpatient drugs to be covered under Medicare Part D. Substantial new provisions affecting compliance also were added. The ACA also revised
the definition of “average manufacturer price” for reporting purposes, which could increase the amount of Medicaid drug rebates to states.

Most judicial, congressional, and executive branch efforts to repeal, modify or delay the implementation of the law have been unsuccessful, and
the law remains in effect.

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. These changes include
aggregate  reductions  to  Medicare  payments  to  providers  of  2%  per  fiscal  year,  which  will  remain  in  effect  through  2030,  unless  additional
Congressional action is taken by Congress. Additional legislative proposals to reform healthcare and government insurance programs, along with
the trend toward managed healthcare in the United States, could influence the purchase of medicines and reduce demand and prices for Innate's
product candidates, if approved. This could harm Innate's or its partners’ ability to market any drugs and generate revenues. Cost containment
measures  that  healthcare  payors  and  providers  are  instituting  and  the  effect  of  further  healthcare  reform  could  significantly  reduce  potential
revenues from the sale of any of its product candidates approved in the future, and could cause an increase in its compliance, manufacturing, or
other operating expenses.

In addition, in the United States, federal programs impose penalties on drug manufacturers in the form of mandatory additional rebates and/or
discounts  if  commercial  prices  increase  at  a  rate  greater  than  the  U.S.  Bureau  of  Labor  Statistics  consumer  price  index,  and  these  rebates  or
discounts, which can be substantial, may affect the Company's ability to raise commercial prices.

24

Further,  there  has  been  increasing  legislative  and  enforcement  interest  in  the  United  States  with  respect  to  drug  pricing  practices. There  have
been several recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring
more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs under
Medicare and reform government program reimbursement methodologies for drugs.

For example, in August 2022, the Inflation Reduction Act of 2022 was signed into law. This legislation contains substantial drug pricing reforms,
including the establishment of a drug price negotiation program within the U.S. Department of Health and Human Services that would require
manufacturers  to  charge  a  negotiated  “maximum  fair  price”  for  certain  selected  drugs  or  pay  an  excise  tax  for  noncompliance. The  IRA  also
imposes penalties on drug manufacturers in the form of mandatory additional rebates and/or discounts if commercial prices increase at a rate
greater than the U.S. Bureau of Labor Statistics consumer price index, and these rebates or discounts, which can be substantial, may affect the
Company's ability to raise commercial prices. The Inflation Reduction Act of 2022 also caps Medicare beneficiaries’ annual out-of-pocket drug
expenses. Substantial penalties can be assessed for noncompliance with the IRA drug pricing provisions. Provisions of the IRA are subject to
legal challenges, and the full impact of the IRA on the pharmaceutical industry remains uncertain.

However,  recent  election  results  in  the  U.S.  may  spark  uncertainty  for  the  IRA. Although  a  full  repeal  of  the  IRA  may  be  unlikely  due  to
budgetary impact, the new U.S. administration could change some of the IRA provisions, including Medicare drug price negotiations.

At  the  state  level,  legislatures  have  increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  and
biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing
cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

In some countries, the proposed pricing for a biopharmaceutical product must be approved before it may be lawfully marketed. In addition, in
certain foreign markets, the pricing of biopharmaceutical products is subject to government control and reimbursement may in some cases be
unavailable. The requirements governing drug pricing vary widely from country to country. For example, the European Union provides options
for its member states to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to
control the prices of medicinal products for human use. An EU member state may approve a specific price for the medicinal product, it may
refuse  to  reimburse  a  product  at  the  price  set  by  the  manufacturer  or  it  may  instead  adopt  a  system  of  direct  or  indirect  controls  on  the
profitability of the company placing the medicinal product on the market. There can be no assurance that any country that has price controls or
reimbursement  limitations  for  biopharmaceutical  products  will  allow  favorable  reimbursement  and  pricing  arrangements  for  any  of  Innate's
products.  Historically,  biopharmaceutical  products  launched  in  the  European  Union  do  not  follow  price  structures  of  the  United  States  and
generally tend to have significantly lower prices.

The  Company  believes  that  pricing  pressures  will  continue  and  may  increase,  which  may  make  it  difficult  for  it  to  sell  any  of  its  product
candidates that may be approved in the future at a price acceptable to the Company or any of its existing or future collaborators.

Any of the Company's product candidates, if approved and commercialized, may fail to achieve market acceptance by physicians, patients,
third-party payors or the medical community to a degree that is necessary for commercial success.

Even if the medical community accepts a product as safe and efficacious for its indicated use, physicians may choose to restrict the use of the
product  if  the  Company  is  unable  to  demonstrate  that,  based  on  experience,  clinical  data,  side-effect  profiles  and  other  factors,  its  drug  is
preferable to any existing drugs

25

or treatments. The Company cannot predict the degree of market acceptance of any product candidate that will receive marketing authorization,
which will depend on a number of factors, including, but not limited to:

•

•

•

•

•

•

•

•

•

•

•

the demonstration of the clinical efficacy and safety of the drug;

the approved labeling for the drug and any required warnings;

prevalence and severity of adverse side effects;

the advantages and disadvantages of the drug compared to alternative treatments;

ease of the drug’s use;

its ability to educate the medical community about the safety and effectiveness of the drug;

the scope of any approval provided by the FDA or foreign regulatory authorities;

publicity about its product or about competitive products;

the coverage and reimbursement policies of government and commercial third-party payors pertaining to the drug;

the market price of its drugs relative to competing treatments; and

due to the rarity of orphan diseases, it could be difficult finding patients seeking treatment.

Poor market penetration could have an adverse effect on the Company's business, prospects, financial condition and results of operations.

Even if some of its product candidates receive marketing authorization, the terms of such approval, ongoing regulation and potential post-
marketing restrictions or withdrawal from the market may limit how the drug may be marketed and may subject the Company to penalties for
failure to comply with regulatory requirements, which could impair its ability to generate revenues.

Even if any of its product candidates receives a marketing authorization, such approval may carry conditions that limit the market for the drug or
put  the  drug  at  a  competitive  disadvantage  relative  to  alternative  therapies.  Regulators  may  limit  the  marketing  of  products  to  particular
indications  or  patient  populations.  Regulators  may  require  warning  labels,  and  drugs  with  warnings  are  subject  to  more  restrictive  marketing
regulations  than  drugs  without  such  warnings.  These  restrictions  could  make  it  more  difficult  to  market  any  drug  effectively.  Marketing
restrictions may reduce the revenue that the Company is able to obtain.

Any of its product candidates for which the Company obtains marketing authorization, and the manufacturing processes, post-approval studies
and measures, labeling, advertising and promotional activities for such products, among other things, will be subject to continual requirements of
and review by the FDA, the EMA and other regulatory authorities. These requirements include submissions of safety and other post-marketing
information  and  reports,  registration  and  listing  requirements,  requirements  relating  to  manufacturing,  quality  control,  quality  assurance  and
corresponding maintenance of records and documents, requirements regarding the distribution of samples to physicians and recordkeeping. Even
if  marketing  authorization  of  a  product  candidate  is  granted,  the  approval  may  be  subject  to  limitations  on  the  indicated  uses  for  which  the
product may be marketed or to the conditions of approval, including the FDA requirement to implement a risk evaluation and mitigation strategy
to ensure that the benefits of a drug or biological product outweigh its risks.

The FDA, EMA and other national authorities may also impose requirements for costly post-marketing studies or clinical trials and surveillance
to  monitor  the  safety  or  efficacy  of  a  product,  such  as  long-term  observational  studies  on  natural  exposure.  The  FDA  and  other  agencies,
including the U.S. Department of

26

Justice, closely regulate and monitor the post-approval marketing and promotion of products to ensure that they are manufactured, marketed and
distributed  only  for  the  approved  indications  and  in  accordance  with  the  provisions  of  the  approved  labeling.  Later  discovery  of  previously
unknown  problems  with  Innate's  product  candidates  or  with  manufacturing  processes,  including  adverse  events  of  unanticipated  severity  or
frequency, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information;
imposition of post-market studies or clinical studies to assess new safety risks, or the imposition of distribution or other restrictions including
suspension  of  production  and/or  distribution  and  withdrawal  of  regulatory  approvals.  Failure  to  comply  with  these  requirements  may  lead  to
financial penalties, compliance expenditures, total or partial suspension of production and/or distribution, product seizure or detention, refusal to
permit  the  import  or  export  of  products,  suspension  of  the  applicable  regulator’s  review  of  a  company’s  submissions,  enforcement  actions,
product recalls, injunctions and even criminal prosecution, any of which could materially and adversely affect the Company's business, financial
condition and results of operations.

The  Company's  future  growth  depends,  in  part,  on  its  ability  to  penetrate  multiple  markets,  in  which  the  Company  would  be  subject  to
additional regulatory burdens and other political, social and geographical risks and uncertainties.

Innate's  future  profitability  will  depend,  in  part,  on  its  ability  to  commercialize  its  product  candidates,  if  approved,  in  markets  in  Europe,  the
United  States  and  other  countries  where  the  Company  maintains  commercialization  rights.  If  the  Company  commercializes  its  product
candidates, if approved, in multiple markets, the Company would be subject to additional risks and uncertainties, including:

•

•

•

•

•

•

•

•

•

•

•

foreign currency exchange rate fluctuations and currency controls;

economic weakness, including inflation, or political instability in particular economies and markets;

potentially adverse and/or unexpected tax consequences, including penalties due to the failure of tax planning or due to the challenge
by tax authorities on the basis of transfer pricing and liabilities imposed from inconsistent enforcement;

the burden of complying with complex and changing regulatory, tax, accounting and legal requirements, many of which vary between
countries;

different medical practices and customs in multiple countries affecting acceptance of drugs in the marketplace;

differing payor reimbursement regimes, governmental payors or patient self-pay systems and price controls;

tariffs or other trade protection measures, trade barriers, import or export licensing requirements or other restrictive actions;

compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;

workforce uncertainty in countries where labor unrest is common;

reduced or loss of protection of intellectual property rights in some foreign countries, and related prevalence of generic alternatives to
therapeutics; and

becoming subject to the different, complex and changing laws, regulations and court systems of multiple jurisdictions and compliance
with a wide variety of foreign laws, treaties and regulations.

27

Political, social and geopolitical conditions in the markets in which our products are developed have been and could continue to be difficult to
predict, resulting in adverse effects on our business. The ongoing armed conflict between Russia and Ukraine, and the escalation of violence and
potential  further  conflicts  in  the  Middle  East,  as  well  as  the  global  geopolitical  situation,  may  affect  regional  stability  and  economic  growth
throughout  the  world.  As  a  result  of  the  2024  presidential  and  legislative  elections  in  the  United  States,  changes  to  applicable  laws  and
regulations that have been announced, proposed, and/or adopted, or could be made or expanded in the future, may result in new or expanded
trade  restrictions  by  the  United  States  and/or  other  countries,  including,  but  not  limited  to,  tariffs  or  import  taxes  being  applied  to  imported
goods,  including  potentially  pharmaceuticals,  and  services  which  could  affect  Innate’s  operations  and  exports  into  the  United  States.  Other
countries may implement trade restrictions and/or retaliatory measures as well.

These and other risks associated with international operations may adversely affect Innate's ability to attain or maintain profitable operations.
Future sales of the Company's product candidates, if they are approved, will be dependent on purchasing decisions of and reimbursement from
government health administration authorities, distributors and other organizations. As a result of adverse conditions affecting the global economy
and credit and financial markets, including disruptions due to political instability or otherwise, these organizations may defer purchases, may be
unable to satisfy their purchasing or reimbursement obligations, or may affect milestone payments or royalties for monalizumab or any of
Innate's product candidates that are approved for commercialization in the future. Should any of these risks materialize, this could have a
material adverse effect on Innate's business, prospects, financial condition and results of operations.

Even if its product candidates obtain regulatory approval, they will be subject to continuous regulatory review.

If marketing authorization is obtained for any of its product candidates, the candidate will remain subject to continuous review, and therefore
authorization could be subsequently withdrawn or restricted. The Company will be subject to ongoing obligations and oversight by regulatory
authorities, including adverse event reporting requirements, marketing restrictions and, potentially, other post-marketing obligations, all of which
may result in significant expense and limit its ability to commercialize such products.

If there are changes in the application of legislation or regulatory policies, or if problems are discovered with a product or its manufacture of a
product, or if the Company or one of its distributors, licensees or co-marketers fails to comply with regulatory requirements, the regulators could
take various actions. These include imposing fines on the Company, imposing restrictions on the product or its manufacture and requiring Innate
to recall or remove the product from the market. The regulators could also suspend or withdraw their marketing authorizations, requiring Innate
to conduct additional clinical studies, change its product labeling or submit additional applications for marketing authorization. If any of these
events  occurs,  its  ability  to  sell  such  product  may  be  impaired,  and  the  Company  may  incur  substantial  additional  expense  to  comply  with
regulatory requirements, which could materially adversely affect its business, financial condition and results of operations.

Even  if  one  of  its  product  candidates  has  orphan  drug  designation,  the  Company  may  not  be  able  to  obtain  any  benefit  from  such
designation.  Furthermore,  if  a  product  is  granted  orphan  drug  exclusivity  in  the  same  indication  for  which  the  Company  is  developing
lacutamab  or  its  other  product  candidates  that  is  granted  orphan  drug  designation,  the  Company  may  not  be  able  to  have  its  product
candidate approved by the applicable regulatory authority for a significant period of time.

Regulatory authorities in some jurisdictions, including the United States and Europe, may designate drugs for relatively small patient populations
as orphan drugs. Under the Orphan Drug Act, the FDA may designate a product candidate as an orphan drug if it is a drug intended to treat a rare
disease or condition

28

which  is  generally  defined  as  a  disease  that  affects  a  patient  population  of  fewer  than  200,000  people  in  the  United  States.  In  the  European
Union,  the  European  Commission  may  designate  a  product  candidate  as  an  orphan  medicinal  product  if  it  is  a  medicine  for  the  diagnosis,
prevention or treatment of life-threatening or very serious conditions that affects not more than five in 10,000 persons in the European Union, or
it is unlikely that marketing of the medicine would generate sufficient returns to justify the investment needed for its development. Generally, if a
product candidate with an orphan drug designation receives the first marketing approval for the indication for which it has such designation, the
product is entitled to a period of marketing exclusivity, which, subject to certain exceptions, precludes the FDA from approving the marketing
application of another drug for the same indication for that time period or precludes the EMA, and other national drug regulators in the European
Union, from accepting the marketing application for another medicinal product for the same indication. The applicable period is seven years in
the United States and ten years in the European Union. In the European Union, the proposed wide-ranging revision of the general pharmaceutical
legislation may pose downside risks to innovation and competitiveness in Europe, primarily due to the modification of regulatory exclusivities
and a stricter incentives framework for orphan medicinal products. Such regulatory proposals could adversely affect the exclusivity period for
our products.

Lacutamab  has  been  granted  orphan  drug  designation  for  cutaneous  T  cell  lymphoma  (CTCL)  in  Europe  and  in  the  United  States,  and  the
Company may pursue orphan drug designation for another product candidate that the Company may develop in the future in the United States
and/or Europe. However, there is no assurance the Company will be able to receive orphan drug designation for other product candidates that the
Company  may  develop  in  the  United  States  and/or  Europe  or  for  any  other  product  candidate  in  any  jurisdiction.  Even  if  the  Company  is
successful  in  obtaining  orphan  drug  designation,  orphan  drug  status  may  not  ensure  that  the  Company  has  market  exclusivity  in  a  particular
market. Even if the Company obtains orphan drug exclusivity for any of its product candidates, that exclusivity may not effectively protect the
product from competition because exclusivity can be suspended under certain circumstances. In the United States, even after an orphan drug is
approved, the FDA can subsequently approve another drug for the same condition if the FDA concludes that the later drug is clinically superior
in that it is shown to be safer, more effective or makes a major contribution to patient care. In the European Union, orphan exclusivity will not
prevent a marketing authorization being granted for a similar medicinal product in the same indication if the new product is safer, more effective
or  otherwise  clinically  superior  to  the  first  product  or  if  the  marketing  authorization  holder  of  the  first  product  is  unable  to  supply  sufficient
quantities of the product. In addition, if another product is granted marketing approval and orphan drug exclusivity in the same indication for
which the Company is developing a product candidate with orphan drug designation, the Company may not be able to have its product candidate
approved by the applicable regulatory authority for a significant period of time.

A  fast  track,  breakthrough  therapy  or  other  designation  by  the  FDA,  or  equivalent  in  other  territories,  may  not  actually  lead  to  a  faster
development.

The  Company  may  seek  fast  track,  breakthrough  therapy  or  similar  designation  for  its  product  candidates.  If  a  product  is  intended  for  the
treatment of a serious or life-threatening condition and the product demonstrates the potential to address unmet medical need for this condition,
the sponsor may apply for FDA fast track designation. The Company has received fast track designation in the U.S. and PRIME designation in
the EU for lacutamab for the treatment of adult patients with relapsed or refractory Sézary Syndrome (SS) who have received at least two prior
systemic  therapies.  In  February  2025,  the  Company  also  received  a  Breakthrough  Therapy  Designation  from  the  FDA  for  lacutamab  for  the
treatment of adult patients with relapsed or refractory Sézary Syndrome after at least two prior systemic therapies including mogamulizumab.

29

A  breakthrough  therapy  is  a  drug  candidate  that  is  intended,  alone  or  in  combination  with  one  or  more  other  drugs,  to  treat  a  serious  or  life-
threatening disease or condition, and that, as indicated by preliminary clinical evidence, may demonstrate substantial improvement over existing
therapies  on  one  or  more  clinically  significant  endpoints,  such  as  substantial  treatment  effects  observed  early  in  clinical  development.  Drugs
designated  as  breakthrough  therapies  by  the  FDA  are  eligible  for  accelerated  approval  and  increased  interaction  and  communication  with  the
FDA designed to expedite the development and review process.

Additionally, the Company may in the future seek equivalent designations in other territories for some of its product candidates that reach the
regulatory review process.

These designations do not ensure that the Company will experience a faster development process, review or approval compared to conventional
FDA procedures. In addition, the FDA may withdraw a designation if it believes that the designation is no longer supported by data from its
clinical development program. A designation alone does not guarantee qualification for the FDA’s priority review procedures.

Priority review designation by the FDA, or the equivalent in other territories, may not lead to a faster regulatory review or approval process
and, in any event, does not assure FDA approval of Innate's product candidates.

If the FDA determines that a product candidate offers major advances in treatment or provides a treatment where no adequate therapy exists, the
FDA  may  designate  the  product  candidate  for  priority  review. A  priority  review  designation  means  that  the  goal  for  the  FDA  to  review  an
application  is  six  months,  rather  than  the  standard  review  period  of  10  months.  The  Company  may  request  priority  review  for  its  product
candidates. The FDA has broad discretion with respect to whether or not to grant priority review status to a product candidate, so even if the
Company  believes  a  particular  product  candidate  is  eligible  for  such  designation  or  status,  the  FDA  may  decide  not  to  grant  it.  Moreover,  a
priority  review  designation  does  not  necessarily  mean  a  faster  regulatory  review  process  or  necessarily  confer  any  advantage  with  respect  to
approval compared to conventional FDA procedures. Receiving priority review from the FDA does not guarantee approval within the six-month
review cycle or thereafter.

The  Company  is  subject  to  healthcare  laws  and  regulations  that  may  require  substantial  compliance  efforts  and  could  expose  Innate  to
criminal  sanctions,  civil  penalties,  contractual  damages,  reputational  harm  and  diminished  profits  and  future  earnings,  among  other
penalties.

Healthcare providers and third-party payors play a primary role in the recommendation and prescription of biologic products that are granted
marketing approval. Arrangements with providers, consultants, third-party payors and customers are subject to broadly applicable federal and
state  laws  and  regulations  that  may  constrain  the  business  and/or  financial  arrangements,  including  those  pertaining  to  fraud  and  abuse,  anti-
kickback, false claims, transparency, and patient data privacy.

Ensuring that Innate's business arrangements with third parties comply with applicable healthcare laws and regulations will continue to require
Innate  to  incur  additional  costs.  It  is  possible  that  governmental  authorities  will  conclude  that  Innate's  business  practices  do  not  comply  with
current  or  future  statutes,  regulations  or  case  law  involving  applicable  fraud  and  abuse  or  other  healthcare  laws  and  regulations.  If  Innate
Pharma's operations were found to be in violation of any of these laws or any other governmental regulations that may apply to us, the Company
may be subject to significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, possible exclusion from
government  funded  healthcare  programs,  such  as  Medicare  and  Medicaid,  additional  reporting  requirements  and  oversight  if  the  Company
becomes subject to a corporate integrity agreement or similar agreement to resolve allegations of non-compliance with these laws, contractual
damages, reputational harm, diminished profits and future earnings, and curtailment of its operations, any of which could substantially disrupt its
operations. If the physicians or other providers or entities with whom the

30

Company expects to do business are found not to be in compliance with applicable laws, they may be subject to criminal, civil or administrative
sanctions, including exclusions from government funded healthcare programs. Should any of these risks materialize, this could have a material
adverse effect on its business, prospects, reputation, financial condition and results of operations.

European  data  collection  is  governed  by  restrictive  regulations  governing  the  collection,  use,  processing  and  cross-border  transfer  of
personal information.

The Company may collect, process, use or transfer personal information from individuals located in the European Union in connection with its
business, including in connection with conducting clinical studies in the European Union. The collection and use of personal health data in the
European Union are governed by the provisions of the General Data Protection Regulation ((EU) 2016/679) (GDPR). This legislation imposes
requirements  relating  to  having  legal  bases  for  processing  personal  information  relating  to  identifiable  individuals  and  transferring  such
information outside of the European Economic Area (EEA), including to the United States, providing details to those individuals regarding the
processing of their personal information, keeping personal information secure, having data processing agreements with third parties who process
personal  information,  responding  to  individuals’  requests  to  exercise  their  rights  in  respect  of  their  personal  information,  reporting  security
breaches involving personal data to the competent national data protection authority and affected individuals, appointing data protection officers,
conducting data protection impact assessments and record-keeping. The GDPR applies across the European Economic Area (EEA) and, by virtue
of the GDPR as it forms part of United Kingdom law, in a broadly uniform manner through section 3 of the European Union (Withdrawal) Act
2018, or the UK GDPR, in the United Kingdom. However, the GDPR provides that EEA member states can make their own further laws and
regulations to introduce specific requirements related to the processing of "special categories of personal data," including personal data related to
health, biometric data used for unique identification purposes and genetic information; as well as personal data related to criminal offenses or
convictions – in the United Kingdom, the United Kingdom Data Protection Act 2018 complements the UK GDPR in this regard. This fact may
lead to greater divergence on the law that applies to the processing of such data types across the EEA and/or United Kingdom, compliance with
which,  as  and  where  applicable,  may  increase  the  Company's  costs  and  could  increase  its  overall  compliance  risk.  Such  country-specific
regulations could also limit its ability to collect, use and share data in the context of the Company's EEA and/or United Kingdom establishments
(regardless of where any processing in question occurs), and/or could cause its compliance costs to increase, ultimately having an adverse impact
on Innate's business and harming its business and financial condition. Failure to comply with the requirements of the GDPR and related national
data protection laws of the member states of the European Union may result in substantial fines, other administrative penalties and civil claims
being  brought  against  us,  which  could  have  a  material  adverse  effect  on  Innate's  business,  prospects,  financial  condition  and  results  of
operations.  Moreover,  in  some  European  countries,  including  France,  there  are  additional  obligations  applicable  to  the  processing  of  personal
data for the purpose of research in the field of healthcare and the hosting of personal health data must be carried out by specifically certified
hosting service providers. Non-compliance with such additional rules as well as the absence or suspension of the appropriate certification of such
hosting service provider may adversely affect Innate Pharma's business, or even lead to penalties related to breach of security of personal data.

Risks Related to Innate's Reliance on Third Parties

The Company has no manufacturing capabilities and relies on third-party manufacturers for its product candidates.

Innate Pharma's product candidates that are tested during its preclinical and clinical studies are manufactured by third parties. The Company has
no production capabilities and relies on third parties to manufacture its products.

This strategy means that the Company does not directly control certain key aspects of its product development, such as:

•

•

•

•

the quality of the product manufactured;

the delivery times for drugs for a given clinical trial;

the clinical and commercial quantities that can be supplied; and

compliance with applicable laws and regulations.

Its  reliance  on  third-party  manufacturers  creates  risks  that  may  not  exist  if  the  Company  had  its  own  manufacturing  capabilities. These  risks
include:

•

•

•

•

•

failure of third-party manufacturers to comply with regulatory and quality control standards;

production of insufficient quantities;

damage during transport and/or storage of its product candidates;

breach of agreements by third-party manufacturers; and

termination or non-renewal of the agreements for reasons beyond its control.

Should its third-party manufacturers breach their obligations or should the Company fail to renew its contracts with them, the Company cannot
guarantee that it will be able to find new suppliers within a timeframe and under conditions that would not be detrimental. The Company could
also  be  faced  with  delays  or  interruptions  in  its  supplies,  which  could  result  in  a  delay  in  the  clinical  trials  and,  ultimately,  a  delay  in  the
commercialization of the product candidates that the Company is developing. For example, manufacturing issues, leading to out-of-specification
product,  can  occur  during  a  manufacturing  campaign  at  the  Contract  Manufacturing  Organization  (CMO)  in  charge  of  the  production  of  its
product candidates.

Reproducing a batch of product is a lengthy and costly process and sometimes can lead to drug shortage that can in turn lead to a delay in the
development of the candidate, or even an early stop of a clinical trial. This happened in the early clinical development of lacutamab and led to
the decision to limit the number of patients in order to ensure drug supply for treated patients in the Phase 1 clinical study.

For example, in November 2019, Impletio Wirkstoffabfüllung GmbH (formerly known as Rentschler Fill Solutions GmbH), the subcontractor in
charge  of  the  fill-and-finish  manufacturing  operations  of  lacutamab,  unilaterally  decided  to  withdraw  the  certificates  of  conformance  of  all
clinical batches produced at their facilities, including the lacutamab batch used for the TELLOMAK Phase 2 clinical study assessing lacutamab
in multiple indications. Impletio Wirkstoffabfüllung GmbH decided to withdraw the certificates of conformance even though the compliance of
its  manufacturing  site  with  Good  Manufacturing  Practices  had  been  confirmed  by  two  on-site  inspections  performed  by  the Austrian  Health
Agency before and after the Company began to work with them.

The transfer of the manufacturing process to another contract manufacturing organization took a few months and came with additional costs but
allowed Innate to have a conform batch in the middle of 2020

32

and to resume the enrollment and treatment of patients in the clinical trials after getting Regulatory Agencies' approval. During this period of
time, the TELLOMAK trial was on partial or full hold in the United States, Spain, Germany and Italy.

Should any of these risks materialize, this could have a material adverse effect on Innate's business, prospects, financial condition and results of
operations.

The  Company  is  reliant  upon  third  parties  to  manufacture  and  supply  components  of  certain  substances  necessary  to  manufacture  its
product candidates.

The  Company  is  reliant  on  several  third-party  CMOs  for  the  manufacture  and  supply  of  components  and  substances  for  all  of  the  product
candidates the Company is developing. In addition, certain component materials are currently available from a single supplier, or a small number
of  suppliers.  The  Company  cannot  be  sure  that  these  suppliers  will  remain  in  business,  or  that  they  will  not  be  purchased  by  one  of  its
competitors or another company that is not interested in continuing to manufacture these materials for the Company. The Company cannot assure
that, if required, the Company will be able to identify alternate sources with the desired scale and capability and establish relationships with such
sources.  A  loss  of  any  CMO  or  component  supplier  and  delay  in  establishing  a  replacement  could  delay  Innate's  clinical  development  and
regulatory approval process.

Its production costs may be higher than the Company currently estimates.

Innate's  product  candidates  are  manufactured  according  to  manufacturing  best  practices  applicable  to  drugs  for  clinical  trials  and  to
specifications approved by the applicable regulatory authorities. If any of its products were found to be non-compliant, the Company would be
required to manufacture the product again, which would entail additional costs and may prevent delivery of the product to patients on time.

Other risks inherent in the production process may have the same effect, such as:

•

•

•

•

•

•

contamination of the controlled atmosphere area;

unusable premises and equipment;

new regulatory requirements requiring a partial and/or extended stop to the production unit to meet the requirements;

unavailable qualified personnel;

power failure of extended duration; and

logistical error.

Should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  its  business,  prospects,  financial  condition  and  results  of
operations.

The Company relies on third parties to supply key materials used in its research and development, to provide services to Innate and to assist
with clinical studies.

The Company makes considerable use of third-party suppliers for the key materials used in its business. The failure of third-party suppliers to
comply with regulatory standards could result in the imposition of sanctions on the Company. These sanctions could include fines, injunctions,
civil penalties, refusal by regulatory organizations to grant approval to conduct clinical trials or marketing authorization for its products, delays,
suspension  or  withdrawal  of  approvals,  license  revocation,  seizure  or  recalls  of  its  products,  operating  restrictions  and  legal  proceedings.
Furthermore, the presence of non-conformities, as detected in regulatory toxicology studies, could result in delays in the development of one or
more of its product candidates and would require further tests to be financed. Although the Company is involved in establishing the protocols for
the production of these materials, the Company does not control all the

33

stages of production and cannot guarantee that the third parties will fulfil their contractual and regulatory obligations. In particular, a partner’s
failure to comply with protocols or regulatory constraints, or repeated delays by a partner, could compromise the development of its products or
limit its liability. Such events could also inflate the product development costs incurred by us.

The  Company  also  uses  third  parties  to  provide  certain  services,  such  as  scientific,  medical  or  strategic  consultancy  services.  These  service
providers are generally selected for their specific expertise, as is the case with the academic partners with whom the Company collaborates. To
build and maintain such a network under acceptable terms, the Company faces intense competition. Such external collaborators may terminate,
at any time, their involvement. The Company can exert only limited control over their activities. The Company may not be able to obtain the
intellectual  property  rights  to  the  product  candidates  or  technologies  developed  under  collaboration,  research  and  license  agreements  under
acceptable terms or at all. Moreover, its scientific collaborators may assert intellectual property rights or other rights beyond the terms of their
engagement.

Finally, the Company uses third-party investigators to assist with conducting clinical trials. All clinical trials are subject to strict regulations and
quality standards. Should any of these risks materialize, this could have a material adverse effect on its business, prospects, financial condition
and results of operations.

The  Company  and  its  collaborators  rely  on  third  parties  to  conduct  some  of  its  preclinical  clinical  studies  and  perform  other  clinical
development  tasks.  If  these  third  parties  do  not  successfully  carry  out  their  contractual  duties,  meet  expected  deadlines  or  comply  with
regulatory requirements, it may not be possible to obtain regulatory approval for, or commercialize, its product candidates, and its business
could be substantially harmed.

The Company has relied upon and plans to continue to rely upon third parties to conduct clinical studies of its product candidates or product
candidates  that  the  Company  has  licensed  to  partners.  For  example,  under  its  license  and  collaboration  agreements  with  AstraZeneca,
AstraZeneca  is  responsible  for  a  number  of  clinical  studies  relating  to  monalizumab,  which  are  subject  to  such  agreements.  In  addition,  the
Company  and  its  collaborators  are  responsible  for  and  are  supporting  several  clinical  studies  that  are  sponsored  by  academic  or  research
institutions, known as investigator-sponsored trials, as is the case for the clinical study assessing IPH5301, which is sponsored by Institut Paoli-
Calmettes and for the clinical study assessing lacutamab in PTCL, sponsored by the Lymphoma Study Association (LYSA). By definition, the
financing, design and conduct of an investigator-sponsored trial are the sole responsibility of the sponsor, and the Company or its collaborators,
as  applicable,  have  limited  control  over  these  aspects  of  these  clinical  trials,  or  the  timing  and  reporting  of  the  data  from  these  trials.  The
Company and its collaborators also depend on independent clinical investigators and CROs to conduct clinical studies. CROs may also assist in
the collection and analysis of data. There are a limited number of CROs that have the expertise to run clinical studies of its product candidates.
Identifying, qualifying and managing performance of third-party service providers can be difficult and time consuming and can cause delays in
its  development  programs.  These  investigators  and  CROs  are  not  Innate's  employees,  and  the  Company  is  not  able  to  control,  other  than  by
contract,  the  amount  of  resources,  including  the  amount  of  time,  that  they  devote  to  Innate's  product  candidates  and  clinical  studies.  If  the
investigators  sponsoring  studies  of  its  product  candidates,  independent  investigators  participating  in  clinical  studies  that  Innate  or  its
collaborators  are  sponsoring  or  CROs  fail  to  devote  sufficient  resources  to  its  clinical  studies  and  development  of  its  product  candidates  or
product candidates the Company has licensed to others, or if their performance is substandard, it may delay or compromise the prospects for
approval  and  commercialization  of  any  product  candidates  that  the  Company  or  its  collaborators  develop.  In  addition,  the  use  of  third-party
service providers requires Innate to disclose its proprietary information to these parties, which could increase the risk that this information will
be misappropriated, and the Company may

34

not be able to obtain adequate remedies for such disclosure or misappropriation. Further, the FDA, EMA and other regulatory authorities require
that the Company complies with standards, commonly referred to as Good Clinical Practice (GCP), and other local legal requirements, including
data privacy regulations, for conducting, recording and reporting clinical trials to assure that data and reported results are credible and accurate
and  that  the  rights,  integrity  and  confidentiality  of  clinical  trial  subjects  are  protected.  If  clinical  investigators  or  CROs  fail  to  meet  their
obligations to Innate or comply with GCP procedures or other applicable legal requirements, the data generated in these trials may be deemed
unreliable, and the FDA, EMA or comparable foreign regulatory authorities may require Innate to perform additional studies before approving
Innate's marketing applications. The Company cannot assure that upon inspection by a given regulatory authority, such regulatory authority will
determine that all of its clinical trials comply with GCP regulations.

In addition, Innate's clinical studies must be conducted with product produced under current Good Manufacturing Practice (cGMP) regulations.
The Company's failure to comply with these regulations may require the Company to repeat clinical trials, which would delay the regulatory
approval  process.  If  clinical  investigators  or  CROs  do  not  successfully  carry  out  their  contractual  duties  or  obligations  or  meet  expected
deadlines, if they need to be replaced or if the quality or accuracy of the data they obtain is compromised due to the failure to adhere to Innate's
protocol or regulatory requirements, or for other reasons, its clinical trials or those of its collaborators may be extended, delayed or terminated,
and the Company or its collaborators may not be able to obtain regulatory approval for or successfully commercialize its product candidates.
Therefore,  its  results  of  operations  and  the  commercial  prospects  for  its  product  candidates  would  be  harmed,  its  costs  could  increase  and  its
ability to generate revenue could be delayed.

Manufacturing facilities and clinical investigational sites are subject to significant government regulations and approvals, and if Innate's or
its  partners’  third-party  manufacturers  fail  to  comply  with  these  regulations  or  maintain  these  approvals,  its  business  could  be  materially
harmed.

Innate's third-party manufacturers are subject to ongoing regulation and periodic inspection by national authorities, including the EMA, FDA and
other regulatory bodies to ensure compliance with cGMP, when producing batches of its product candidates for clinical trials. CROs and other
third-party  research  organizations  must  also  comply  with  Good  Laboratory  Practices  (GLP)  when  carrying  out  regulatory  toxicology  studies.
Any  failure  to  follow  and  document  the  Company's  or  third  parties'  adherence  to  such  GMP  and  GLP  regulations  or  other  regulatory
requirements may lead to significant delays in the availability of products for commercial sale or clinical trials, may result in the termination of
or a hold on a clinical trial, or may delay or prevent filing or approval of marketing applications for its products.

Failure to comply with applicable regulations could also result in national authorities, the EMA, FDA or other applicable regulatory authorities
taking various actions, including:

•

•

•

•

•

•

•

levying fines and other civil penalties;

imposing consent decrees or injunctions;

requiring Innate to suspend or put on hold one or more of its clinical trials;

suspending or withdrawing regulatory approvals;

delaying or refusing to approve pending applications or supplements to approved applications;

requiring Innate to suspend manufacturing activities or product sales, imports or exports;

requiring Innate to communicate with physicians and other customers about concerns related to actual or potential safety, efficacy and
other issues involving its products;

35

•

•

•

mandating product recalls or seizing products;

imposing operating restrictions; and

seeking criminal prosecutions.

Any of the foregoing actions could be detrimental to Innate's reputation, business, financial condition or operating results. Furthermore, its key
suppliers  may  not  continue  to  be  in  compliance  with  all  applicable  regulatory  requirements,  which  could  result  in  its  failure  to  produce  its
products on a timely basis and in the required quantities, if at all. In addition, before any additional products would be considered for marketing
authorization in Europe, the United States or elsewhere, its suppliers will have to pass an inspection by the applicable regulatory agencies. The
Company is dependent on its suppliers’ cooperation and ability to pass such inspections, and the inspections and any necessary remediation may
be costly. Failure to pass such inspections by Innate or any of its suppliers would affect its ability to commercialize its product candidates in
Europe,  the  United  States  or  elsewhere.  Should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  on  the  Company's
business, prospects, financial condition and results of operations.

The Company depends upon its existing collaboration partners, AstraZeneca, Sanofi and other third parties, and may depend upon future
collaboration partners to commit to the research, development, manufacturing and marketing of its drugs.

The  Company  has  significant  collaborations  with  AstraZeneca  for  the  development  of  monalizumab  and  IPH5201.  The  Company  also
collaborates with Sanofi for the development of IPH6401/SAR’514 and IPH62, and the Company may enter into additional collaborations for
other of its product candidates or technologies in development. The Company cannot control the timing or quantity of resources that its existing
or future collaborators will dedicate to research, preclinical and clinical development, manufacturing or marketing of its products, or whether
collaborators may terminate licenses, agreements or other arrangements, such as Takeda's termination of its license or Sanofi’s termination with
respect  to  IPH6101/SAR'579.  Innate's  collaborators  may  not  perform  their  obligations  according  to  its  expectations  or  standards  of  quality.
Innate's  collaborators  could  terminate  its  existing  agreements  for  a  number  of  reasons,  including  that  they  may  have  other,  higher  priority
products  in  development  or  because  its  partnered  programs  may  no  longer  be  a  priority  for  them.  If  any  of  the  Company's  collaboration
agreements were to be terminated and potentially due to any such terminations, the Company could encounter significant delays in developing its
product  candidates,  lose  the  opportunity  to  earn  any  revenues  Innate  expected  to  generate  under  such  agreements,  incur  unforeseen  costs  and
suffer damage to the reputation of its product, product candidates and as a company generally.

In order to optimize the launch and market penetration of certain of its future product candidates, the Company may enter into distribution and
marketing  agreements  with  pharmaceutical  industry  leaders.  For  these  product  candidates,  the  Company  would  not  market  its  products  alone
once they have obtained marketing authorization. The risks inherent in entry into these contracts are as follows:

•

•

•

the negotiation and execution of these agreements is a long process that may not result in an agreement being signed or that can delay
the development or commercialization of the product candidate concerned;

these  agreements  are  subject  to  cancellation  or  non-renewal  by  its  collaborators  or  may  not  be  fully  complied  with  by  its
collaborators;

in the case of a license granted by Innate, the Company loses control of the development of the product candidate licensed; in such
cases the Company would have only limited control over the means and resources allocated by its partner for the commercialization
of its product; and

36

•

collaborators may not properly obtain, maintain, enforce or defend Innate's intellectual property or proprietary rights or may use its
proprietary information in such a way as to invite litigation that could jeopardize or invalidate its proprietary information or expose
the Company to potential litigation.

Should any of these risks materialize, or should the Company fails to find suitable collaborators, this could have a material adverse effect on its
business, prospects, financial condition and results of operations.

The late-stage development and marketing of its product candidates may partially depend on its ability to establish collaborations with major
biopharmaceutical companies.

In  order  to  develop  and  market  some  of  its  product  candidates,  the  Company  relies  on  collaboration,  research  and  license  agreements  with
pharmaceutical  companies  to  assist  Innate  in  the  development  of  product  candidates  and  the  financing  of  their  development.  For  its  most
advanced clinical product candidate, monalizumab, the Company entered into an agreement with AstraZeneca, in part because of their late-stage
development and marketing capabilities. As the Company identifies new product candidates, Innate will determine the appropriate strategy for
development and marketing, which may result in the need to establish collaborations with major biopharmaceutical companies. Innate may also
enter into agreements with institutions and universities to participate in its other research programs and to share intellectual property rights.

The Company may fail to find collaboration partners and to sign new agreements for its other product candidates and programs. The competition
for partners is intense, and the negotiation process is time-consuming and complex. Any new collaboration may be on terms that are not optimal
for us, and the Company may not be able to maintain any new collaboration if, for example, development or approval of a product candidate is
delayed,  sales  of  an  approved  product  candidate  do  not  meet  expectations  or  the  collaborator  terminates  the  collaboration.  Any  such
collaboration,  or  other  strategic  transaction,  may  require  Innate  to  incur  non-recurring  or  other  charges,  increase  Innate's  near-  and  long-term
expenditures  and  pose  significant  integration  or  implementation  challenges  or  disrupt  its  management  or  business.  These  transactions  would
entail numerous operational and financial risks, including exposure to unknown liabilities; disruption of Innate's business and diversion of its
management’s  time  and  attention  in  order  to  manage  a  collaboration  or  develop  acquired  products,  product  candidates  or  technologies;
incurrence  of  substantial  debt  or  dilutive  issuances  of  equity  securities  to  pay  transaction  consideration  or  costs;  higher  than  expected
collaboration,  acquisition  or  integration  costs;  write-downs  of  assets  or  goodwill  or  impairment  charges;  increased  amortization  expenses;
difficulty  and  cost  in  facilitating  the  collaboration  or  combining  the  operations  and  personnel  of  any  acquired  business;  and  impairment  of
relationships  with  key  suppliers,  manufacturers  or  customers  of  any  acquired  business  due  to  changes  in  management  and  ownership  and  the
inability to retain key employees of any acquired business. Accordingly, although there can be no assurance that the Company will undertake or
successfully complete any transactions of the nature described above, any transactions that the Company does complete may be subject to the
foregoing  or  other  risks  and  have  a  material  and  adverse  effect  on  its  business,  financial  condition,  results  of  operations  and  prospects.
Conversely,  any  failure  to  enter  any  additional  collaboration  or  other  strategic  transaction  that  would  be  beneficial  to  Innate  could  delay  the
development  and  potential  commercialization  of  its  product  candidates  and  have  a  negative  impact  on  the  competitiveness  of  any  product
candidate that reaches market.

The  Company  does  not  and  will  not  have  access  to  all  information  regarding  its  product  candidates  that  are  subject  to  collaboration  and
license agreements. Consequently, its ability to inform its

37

shareholders about the status of product candidates that are subject to these agreements, and its ability to make business and operational
decisions, may be limited.

Innate  does  not  and  will  not  have  access  to  all  information  regarding  its  product  candidates  that  are  subject  to  its  license  and  collaboration
agreements with AstraZeneca, Sanofi and other third parties, including potentially material information about clinical trial design, execution and
timing,  safety  and  efficacy,  clinical  trial  results,  regulatory  affairs,  manufacturing,  marketing  and  other  areas  known  by  its  collaborators.  In
addition,  the  Company  has  confidentiality  obligations  under  its  collaboration  and  license  agreements.  Therefore,  its  ability  to  keep  its
shareholders informed about the status of product candidates subject to such agreements will be limited by the degree to which its collaborators
keep  Innate  informed  and  allow  Innate  to  disclose  information  to  the  public  or  provide  such  information  to  the  public  themselves.  If  its
collaborators  do  not  inform  Innate  about  its  product  candidates  subject  to  agreements  with  them,  the  Company  may  make  operational  and
investment decisions that the Company would not have made had the Company been fully informed, which may have an adverse impact on its
business, prospects, financial condition and results of operations.

Risks Related to Innate Pharma's Financial Position and Capital Needs

The Company has incurred and may in the future incur significant operational losses related to its research and development activities.

The  Company  has  incurred  net  losses  in  each  year  since  its  inception  except  for  the  years  ended  December  31,  2016  and  2018.  Innate's  net
income (loss) was €(49.5) million and €(7.6) million for the years ended December 31, 2024 and 2023, respectively. Substantially all of its net
losses  resulted  from  costs  incurred  in  connection  with  its  development  programs  and  from  selling,  general  and  administrative  expenses
associated with its ongoing operations. The Company expects to incur significant expenses and operating losses for the foreseeable future.

The net loss for the year ended December 31, 2024 leads to negative equity of €(26.4) million for a share capital of €4.2 million, meaning that
the Company's equity is less than half of its share capital. In accordance with the provisions of Article L. 225-248 of the French Commercial
Code,  a  resolution  will  be  submitted  to  the  annual  general  meeting  of  the  shareholders  of  the  Company  (the  “General  Meeting”)  on  May  22,
2025, to decide whether the Company should be dissolved early pursuant to French corporate law and subject to additional delay periods.

The  likelihood  and  amount  of  its  future  operational  losses  will  depend  on  several  factors,  including  the  pace  and  amount  of  its  future
expenditures in connection with its product candidates and development programs and its ability to obtain funding through milestone or royalty
payments  under  its  license  and  collaboration  agreements,  equity  or  debt  financings,  strategic  collaborations  and  government  grants  and  tax
credits. The Company expects that its main source of income for the near- and medium-term will be:

•

•

payments received under its license and collaboration agreements with third parties, including AstraZeneca and Sanofi; and

government grants and research tax credits.

The  interruption  of  one  or  more  of  those  sources  of  income  could  have  a  material  adverse  effect  on  Innate's  business,  prospects,  financial
condition and results of operations.

The Company's ability to be profitable in the future will depend on its ability to generate revenue from sales relating to its product candidates, if
approved, and its ability to obtain regulatory approval for marketing its product candidates. If its product candidates receive regulatory approval,
its future revenues will depend upon the size of any markets in which its product candidates have received approval, and

38

market  acceptance,  reimbursement  from  third-party  payors  and  market  share.  Any  of  these  factors  could  have  a  material  adverse  effect  on
Innate's business, prospects, financial condition and results of operations.

The Company may need to raise additional funding to complete the development and any commercialization of its product candidates, which
may not be available on acceptable terms, or at all, and failure to obtain this necessary capital when needed may force it to delay, limit or
terminate its product development efforts or other operations.

Innate  is  currently  advancing  its  product  candidates  through  preclinical  and  clinical  development,  and  anticipates  relying  on  partners  as  the
Company advances them. Innate currently retains the full development and marketing rights to lacutamab, IPH5301, IPH6501 and IPH4502, and
may retain rights to additional proprietary product candidates in the future. The development of immunotherapy product candidates is expensive,
and Innate expects its research and development expenses to increase as the Company advances its product candidates through clinical studies
and  regulatory  approvals.  If  clinical  studies  are  successful  and  if  Innate  obtains  regulatory  approval  for  product  candidates  that  the  Company
develops, Innate expects to incur commercialization expenses before these product candidates are marketed and sold.

The Company anticipates that its expenses will increase substantially if and as it:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

continues its research, preclinical and clinical development of its product candidates if its current collaboration partners cease their
collaborations with us;

expands the scope of its current clinical studies for its product candidates;

initiates additional preclinical, clinical or other studies for its product candidates;

further develops manufacturing processes for its product candidates;

changes or adds additional manufacturers or suppliers;

seeks regulatory and marketing authorizations for its product candidates that successfully complete clinical studies;

establishes  a  sales,  marketing  and  distribution  infrastructure  to  commercialize  any  product  for  which  the  Company  may  obtain
marketing authorization;

seeks to identify and validate additional product candidates that may result in additional preclinical, clinical or other product studies;

acquires or in-license agreements or other product candidates and technologies;

makes milestone or other payments under any in-license agreements;

maintains, protects, defends and expands its intellectual property portfolio;

attracts and retains new and existing skilled personnel;

creates additional infrastructure to support its operations as a public company in the United States; and

experiences any delays or encounters issues with any of the above.

As of December 31, 2024, the Company had cash, cash equivalents, short-term investments and non-current financial assets of €91.1 million.
The  Company  believes  its  cash,  cash  equivalents,  short-term  investments  and  non-current  financial  assets,  together  with  its  cash  flow  from
operations, will be sufficient to fund its operations until mid 2026. However, in order to complete the development process, obtain regulatory
approval and, if approved, commercialize its product candidates that the Company is

39

developing  in-house,  including  lacutamab,  IPH5301,  IPH6501  and  IPH4502;  develop  its  proprietary  technology;  and  develop  a  pipeline  of
additional  product  candidates,  the  Company  will  require  additional  funding.  Innate's  existing  resources  may  not  be  sufficient  to  cover  any
additional  financing  needs,  in  which  case  new  funding  would  be  required.  See  “—the  Company  has  incurred  and  may  in  the  future  incur
significant operational losses related to its research and development activities.” The conditions and arrangements for such new financing would
depend,  among  other  factors,  on  economic  and  market  conditions  that  are  beyond  its  control,  including  the  current  volatility  in  the  capital
markets.

Any additional fundraising efforts may divert Innate's management from their day-to-day activities, which may adversely affect the Company's
ability to develop and commercialize its product candidates. In addition, the Company cannot guarantee that future financing will be available in
sufficient  amounts  or  on  terms  acceptable  to  us,  if  at  all.  Under  French  law,  Innate's  share  capital  may  be  increased  only  with  shareholders’
approval  at  an  extraordinary  general  shareholders’  meeting  on  the  basis  of  a  report  from  the  Executive  Board.  In  addition,  the  French
Commercial Code imposes certain limitations on Innate's ability to price certain offerings of its share capital without preferential subscription
rights (droit préférentiel de souscription), which limitation may prevent Innate from successfully completing any such offering.

Moreover,  the  terms  of  any  financing  may  adversely  affect  the  holdings  or  the  rights  of  Innate's  shareholders,  and  the  issuance  of  additional
securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of its ordinary shares or the ADSs to
decline. The sale of additional equity or convertible securities would dilute its shareholders. The Company may seek funds through arrangements
with collaborative partners or otherwise at an earlier stage of product development than otherwise would be desirable, and the Company may be
required to relinquish rights to some of its technologies or product candidates or otherwise agree to terms unfavorable to Innate Pharma, any of
which may have a material adverse effect on its business, prospects, financial condition and results of operations.

If  the  Company  needs  and  is  unable  to  obtain  funding  on  a  timely  basis,  the  Company  may  be  required  to  significantly  curtail,  delay  or
discontinue one or more of its research or development programs or the commercialization of any product or product candidate, or the Company
may be unable to expand its operations or otherwise capitalize on its business opportunities as desired, which could impair its growth prospects.
Should any of these risks materialize, this could have a material adverse effect on Innate's business, prospects, financial condition and results of
operations.

The  terms  of  Innate's  loans  agreements  with  Société  Générale,  BNP  Paribas  and  certain  other  loan  obligations  place  restrictions  on  its
operating and financial flexibility.

In July 2017, the Company entered into a loan and security agreement with Société Générale (the “Loan Agreement”) in order to finance the
construction of its future headquarters. The Loan Agreement is secured by collateral in the form of financial instruments valued at €15.2 million
held  at  Société  Générale. As  of  December  31,  2024,  Innate  had  drawn  down  €15.2  million  under  the  Loan Agreement. The  Loan Agreement
subjects Innate to a covenant to maintain a minimum balance of its total cash, cash equivalents and current and non-current financial assets as of
each fiscal year end at least equal to the amount of outstanding principal under the Loan Agreement. Compliance with this covenant may limit its
flexibility in operating its business and its ability to take actions that might be advantageous to Innate and its shareholders. For example, if the
Company fails to meet its minimum cash covenant and Innate is unable to raise additional funds or obtain a waiver or other amendment to the
Loan Agreement, Innate may be required to delay, limit, reduce or terminate certain of its clinical development efforts.

Additionally, Innate may be required to repay the entire amount of outstanding indebtedness under the Loan Agreement in cash if the Company
fails to stay in compliance with its covenant or suffer some other event of default under the Loan Agreement. Under the Loan Agreement, an
event of default will occur if,

40

among other things, Innate fails to make payments under the Loan Agreement or Innate breaches its covenant under the Loan Agreement. The
Company may not have enough available cash or be able to raise additional funds through equity or debt financings to repay such indebtedness
at the time any such event of default occurs. In that case, Innate may be required to delay, limit, reduce or terminate its clinical development
efforts or grant rights to others to develop and market product candidates that the Company would otherwise prefer to develop and market itself.
Société Générale could also exercise its rights as collateral agent to take possession and dispose of the collateral securing the loan for its benefit.
Innate's business, financial condition and results of operations could be substantially harmed as a result of any of these events.

On January 5, 2022, the Company announced that it had obtained €28.7 million in non-dilutive financing in the form of two State Guaranteed
Loans from Société Générale (€20.0 million) and BNP Paribas (€8.7 million). The Company received the funds related to these two loans on
December 27 and 30, 2021, respectively. Both loans have an initial maturity of one year with an option to extend to five years. They are 90%
guaranteed by the French government as part of the package of measures put in place by the French government to support companies during the
COVID-19 pandemic. The effective interest rate applied to these contracts is 0.5%, which is the contractual rate for repayment within one year.

On August 2022, the Company requested the extension repayment of the non-dilutive financing of €28.7 million obtained in December 2021 in
the form of two State Guaranteed Loans (“PGE”), respectively, for 20.0 and 8.7 million euros for an additional period of five years starting in
2022 and including a one-year grace period. Consequently, the Company has obtained agreements from Société Générale and BNP Paribas. The
effective interest rates applied to these contracts during the additional period are 1.56% and 0.95% for Société Générale and BNP Paribas loans,
respectively,  excluding  insurance  and  guarantee  fees,  with  an  amortization  exemption  for  the  entire  year  2023.  During  this  grace  period,  the
Company was only liable for the payment of interest and the guarantee fees, with amortization of the two loans starting in 2024 over a period of
four years.

If Innate does not achieve its product development or commercialization objectives in the timeframes Innate expects, the Company may not
receive product revenue or milestone or royalty payments, and Innate Pharma may not be able to conduct its operations as planned.

Innate  has  received  and  expects  to  continue  to  receive  payments  from  its  collaborators  when  the  Company  satisfies  certain  pre-specified
milestones in its licensing or collaboration agreements. Innate currently depends to a large degree on these milestone payments from its existing
collaborators in order to fund its operations, and Innate may enter into new collaboration agreements that also provide for milestone payments.
For example, the Company has granted options to license or acquire intellectual property rights in certain of its programs to its collaborators
which, if exercised, will result in up-front option exercise fees and, assuming Innate meets all specified development, clinical, regulatory and
sales milestones, could result in substantial milestone payments. These milestone payments are generally dependent on the accomplishment of
various  scientific,  clinical,  regulatory,  sales  and  other  product  development  objectives,  and  the  successful  or  timely  achievement  of  many  of
these milestones is outside of its control, in part because some of these activities are being or will be conducted by its collaborators. If Innate or
its collaborators fail to achieve the applicable milestones, Innate Pharma may not receive such milestone payments. A failure to receive any such
milestone payment may cause Innate to:

•

•

•

delay, reduce or terminate certain research and development programs;

reduce headcount;

raise funds through additional equity or convertible debt financings that could be dilutive to its shareholders and holders of its ADSs;

41

•

•

•

obtain funds through collaboration agreements that may require Innate to assign rights to technologies or products that Innate would
have otherwise retained;

sign new collaboration or license agreements that may be less favorable than those the Company would have obtained under different
circumstances; and

consider strategic transactions or engaging in a joint venture with a third party.

In addition, although Innate may be eligible to receive an aggregate of approximately $2.8 billion in future contingent payments from existing
collaboration  agreements  and  any  license  agreements  that  become  effective  upon  the  exercise  by  its  collaborators  of  options  to  license  future
product  candidates,  there  is  no  guarantee  that  the  Company  will  receive  any  contingent  payments  or  that  its  collaborators  will  exercise  any
options to license or acquire additional intellectual property rights in any of its programs. If its collaborators decide not to exercise such options
with respect to a program, the Company will not receive the up-front option exercise fee and will not be eligible to receive any of the related
commercial,  development,  royalty  or  other  milestone  payments.  Even  if  its  collaborators  exercise  such  options  with  respect  to  a  particular
program, Innate may never achieve the related milestones for any number of reasons. The failure to receive milestone or royalty payments and
the occurrence of any of the events above may have a material adverse impact on Innate's business, prospects, financial condition and results of
operations.

The revenues generated from its collaboration and license agreements have contributed and are expected to contribute a large portion of its
revenue for the foreseeable future.

The  Company  has  entered  into  collaboration  and  license  agreements  with  pharmaceutical  companies,  including AstraZeneca  and  Sanofi. The
upfront payments and milestones received from its partners were €19.0 million, €31.6 million and €56.9 million for the years ended December
31, 2024, 2023 and 2022, respectively.

Innate  also  enhances  its  research  efforts  by  establishing  collaborations  with  academic  or  non-profit  research  institutions  and  other
biopharmaceutical companies. The participation in these collaborations may generate revenue and funding in the form of operating grants or the
reimbursement of research and development expenses.

Innate may not be able to renew or maintain its license agreements or collaborative research contracts or may be unable to sign new agreements
with new collaborators on reasonable terms or at all. The early termination of a contract, the non-renewal of a contract or Innate's inability to
find new collaborators would adversely affect its business. Should any of these risks materialize, this could have an adverse effect on Innate's
business, prospects, financial condition and results of operations.

The Company benefits from tax credits in France that could be reduced or eliminated.

As  a  French  biopharmaceutical  company,  Innate  benefits  from  certain  tax  advantages,  including  the  French  research  tax  credit  (Crédit  Impôt
Recherche) (the "Research Tax Credit"), which is a French tax credit aiming at stimulating research and development. The Research Tax Credit
is  calculated  based  on  Innate's  claimed  amount  of  eligible  research  and  development  expenditures  in  France  and  represented  €7.5  million,
€9.7  million  and  €7.9  million  for  the  years  ended  December  31,  2024,  2023  and  2022,  respectively.  The  Research  Tax  Credit  is  a  source  of
financing to Innate that could be reduced or eliminated by the French tax authorities or by changes in French tax law or regulations. See “Item
10E.—Taxation  –  Material  French  Tax  Considerations”  and  “Note  1.2.—  Government  financing  for  research  expenditures”  of  this  Annual
Report.

The  Research  Tax  Credit  can  be  offset  against  French  corporate  income  tax  due  by  the  company  with  respect  to  the  year  during  which  the
eligible research and development expenditures have been made. The

42

portion of tax credit in excess which is not being offset, if any, represents a receivable against the French Treasury which can in principle be
offset against the French corporate income tax due by the company with respect to the three following years. The remaining portion of tax credit
not being offset upon expiry of such a period may then be refunded to the company.

As  soon  as  the  Company  qualifies  as  small-  and  medium-size  business,  the  French  Treasury  refunds  immediately  (meaning  that,  in  practice,
Innate  can  receive  the  refund  during  the  year  following  the  year  in  which  the  eligible  research  and  development  expenditures  are  made)  the
Research Tax Credit claims. If the Company does not qualify for this status, the Research Tax Credit claims will be reimbursed within the expiry
of a period of three years. The history of the Company's status and of the incomes related to the Research Tax Credit is detailed in the Notes to
financial statements, section 2), paragraph q) of the present document.

The  French  tax  authorities,  with  the  assistance  of  the  Higher  Education  and  Research  Ministry,  may  audit  each  research  and  development
program in respect of which a Research Tax Credit benefit has been claimed and assess whether such program qualifies in their view for the
Research  Tax  Credit  benefit.  The  French  tax  authorities  may  challenge  Innate's  eligibility  for,  or  its  calculation  of,  certain  tax  reductions  or
deductions in respect of its research and development activities (and therefore the amount of Research Tax Credit claimed), or the accelerated
reimbursement allowed for small- and medium-size businesses and the Company's credits may be reduced, which would have a negative impact
on its revenue and future cash flows.

Furthermore,  the  French  Parliament  may  decide  to  eliminate,  or  to  reduce  the  scope  or  the  rate  of,  the  Research Tax  Credit  benefit,  either  of
which it could decide to do at any time. If Innate fails to receive future Research Tax Credit amounts or if its calculations are challenged, even if
Innate  Pharma  complies  with  the  current  requirements  in  terms  of  documentation  and  eligibility  of  its  expenditure,  its  business,  prospects,
financial condition and results of operations could be adversely affected.

The Company may be unable to carry forward existing tax losses.

Innate has accumulated tax loss carry forwards of €536.8 million as of December 31, 2024. Applicable French law provides that, for fiscal years
ending after December 31, 2012, the use of these tax losses is limited to €1.0 million, plus 50% of the portion of net earnings exceeding this
amount. The unused balance of the tax losses in application of such rule can be carried forward to future fiscal years, under the same conditions
and without time restriction. There can be no assurance that future changes to applicable tax law and regulation will not eliminate or alter these
or other provisions in a manner unfavorable to us, which could have an adverse effect on Innate's business, prospects, financial condition, cash
flows or results of operations.

Innate's business may be exposed to foreign exchange risks.

The Company incurs some of its expenses, and derives certain of its revenues, in currencies other than the euro. In particular, as Innate expands
its  operations  and  conducts  clinical  studies  in  the  United  States,  Innate  will  incur  expenses  in  U.S.  dollars. As  a  result,  Innate  is  exposed  to
foreign currency exchange risk as its results of operations and cash flows are subject to fluctuations in foreign currency exchange rates.

The  Company  currently  does  not  engage  in  hedging  transactions  to  protect  against  uncertainty  in  future  exchange  rates  between  particular
foreign currencies and the euro. Therefore, an unfavorable change in the value of the euro against the U.S. dollar could have a negative impact
on its revenue and earnings growth. Innate cannot predict the impact of foreign currency fluctuations, and foreign currency fluctuations in the
future may adversely affect its financial condition, results of operations and cash flows. The ADSs being offered in the U.S. offering are quoted
in U.S. dollars on the Nasdaq, while Innate's ordinary shares trade in euro on Euronext Paris. Innate's financial statements are prepared in euro.

43

Therefore,  fluctuations  in  the  exchange  rate  between  the  euro  and  the  U.S.  dollar  will  also  affect,  among  other  matters,  the  value  of  Innate's
ordinary shares and ADSs.

Under  Innate's  license  and  collaboration  agreements  with AstraZeneca,  the  payments  the  Company  receives  are  in  U.S.  dollars.  The  level  of
completion of the operations covered by this collaboration agreement is based on the costs converted at the historical exchange rate. The effects
of  reevaluation  therefore  have  no  impact  on  the  technical  progress  used  for  revenue  recognition.  Consequently,  there  may  be  a  difference
between the level of completion that would take into account the last known rate and the level of completion as calculated. This difference could
result in a future exchange gain or loss.

Moreover,  in  the  future,  Innate  could  generate  part  of  its  sales  in  the  United  States  and  part  in  Europe  and  could  therefore  be  subject  to  an
unfavorable euro/dollar exchange rate. Therefore, for example, an increase in the value of the euro against the U.S. dollar could be expected to
have a negative impact on its revenue and earnings growth as U.S. dollar revenue and earnings, if any, would be translated into euro at a reduced
value.  The  Company  could  also  sign  contracts  denominated  in  other  currencies,  which  would  increase  its  exposure  to  currency  risk.  In
accordance with Innate's business decisions, its exposure to this type of risk could change depending on:

•

•

•

•

the currencies in which Innate receives its revenues;

the currencies chosen when agreements are signed, such as licensing agreements, or co-marketing or co-development agreements;

the location of clinical trials on product candidates; and

its policy for insurance cover.

At present, Innate has not put any specific hedging arrangements in place to address these risks. Should any of these risks materialize, this could
have a material adverse effect on its business, prospects, financial condition and results of operations.

Changes to U.S. and non-U.S. tax laws could materially adversely affect Innate Pharma.

The Company is unable to predict what tax law may be proposed or enacted in the future or what effect such changes would have on its business,
but such changes, to the extent they are brought into tax legislation, regulations, policies or practices, could affect its effective tax rates in the
future  in  countries  where  it  has  operations  and  could  have  an  adverse  effect  on  its  overall  tax  rate  in  the  future,  along  with  increasing  the
complexity, burden and cost of tax compliance. The Company urges its shareholders and holders of its ADSs to consult with their legal and tax
advisors with respect to the potential tax consequences of investing in or holding Innate's ordinary shares or ADSs.

Tax authorities may disagree with Innate's positions and conclusions regarding certain tax positions, resulting in unanticipated costs, taxes
or non-realization of expected benefits.

A  tax  authority  may  disagree  with  tax  positions  that  the  Company  has  taken,  which  could  result  in  increased  tax  liabilities.  For  example,  the
French  tax  authorities,  the  U.S.  Internal  Revenue  Service  or  another  tax  authority  could  challenge  Innate's  allocation  of  income  by  tax
jurisdiction  and  the  amounts  paid  between  its  affiliated  companies  pursuant  to  its  intercompany  arrangements  and  transfer  pricing  policies,
including amounts paid with respect to its intellectual property development. Similarly, a tax authority could assert that the Company is subject
to tax in a jurisdiction where Innate believes it has not established a taxable connection, often referred to as a “permanent establishment” under
international tax treaties, and such an assertion, if successful, could increase the Company's expected tax liability in one or more jurisdictions. A
tax  authority  may  take  the  position  that  material  income  tax  liabilities,  interest  and  penalties  are  payable  by  us,  in  which  case,  the  Company
expects that it might contest such assessment.

44

Contesting such an assessment may be lengthy and costly, and if Innate was unsuccessful in disputing the assessment, the result could increase
its anticipated effective tax rate.

In 2022 and 2023, the Company was subject to tax inspections by the French tax authorities, in particular one tax inspection from the French tax
authorities relating to fiscal years 2018 to 2021 that resulted in an adjustment of €1.4 million.

Risks Related to Innate Pharma's Organization and Operations

In the past there have been material weaknesses in the Company's internal control over financial reporting and if Innate Pharma is unable
to  maintain  effective  internal  controls  over  financial  reporting,  the  accuracy  and  timeliness  of  its  financial  reporting  may  be  adversely
affected, which could hurt its business and/or lessen investor confidence.

The Company must maintain effective internal control processes over financial reporting in order to accurately report its results of operations and
financial condition on a timely basis. A company’s internal control over financial reporting is a process designed by, or under the supervision of,
a company’s principal executive and principal financial officers, or persons performing similar functions, and effected by a company’s Executive
Board, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of
financial statements in accordance with generally accepted accounting principles.

As a public company listed in the United States, the Sarbanes-Oxley Act requires, among other things, that the Company assess the effectiveness
of  its  internal  control  over  financial  reporting  as  of  the  end  of  each  fiscal  year. As  the  Company  lost  its  "emerging  growth  company"  (EGC)
status as of December 31, 2024, Innate's independent registered public auditor is now required to attest to and report on the effectiveness of its
internal controls over financial reporting.

In this context, in order to comply with Section 404(b) of the Sarbanes-Oxley Act within the prescribed timeframe, and over the last five years,
the  Company  has  reinforced  its  internal  control  processes  and  has  implemented  a  standard  and  more  robust  Information  System  including  an
Enterprise Resource Planning (ERP) tool supporting the production and the management of its financial information. Some material weaknesses
were identified as of December 31, 2020 and 2022.

Under  standards  established  by  the  Public  Company  Accounting  Oversight  Board,  a  material  weakness  is  a  deficiency  or  combination  of
deficiencies in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement in Innate's annual
or  interim  financial  statements  will  not  be  prevented  or  detected  and  corrected  on  a  timely  basis. These  deficiencies  concerned,  respectively,
process and controls relating to the processing of manual entries and significant and unusual transactions, and controls aimed at preventing or
detecting  material  errors  in  the  classification  and  presentation  of  the  consolidated  financial  statements,  as  well  as  in  the  corresponding
disclosures  and  the  recording  of  all  subcontracting  expenses  over  the  correct  period.  The  Company  took  steps  to  address  these  material
weaknesses and implemented remediation plans. For a discussion about these remediation measures, see "Item 15. Controls and Procedures" of
this Annual Report.

The Company's management carried out an evaluation of the effectiveness of its internal control at the end of the year ended December 31, 2024.
Management  concluded  that,  as  of  December  31,  2024,  the  Company's  internal  control  over  financial  reporting  was  effective  to  provide
reasonable assurance regarding the reliability of its financial reporting and the preparation of its financial statements for external purposes. See
"Item 15. Controls and Procedures" of this Annual Report.

45

The Company cannot give any assurance that it will be able to maintain the appropriate level of control to prevent future material weaknesses.
See “Risk Factors—The Company incurs significant costs as a result of being a public company.”

Innate's  internal  computerized  systems,  or  those  of  its  third-party  contractors  or  consultants,  may  fail  or  suffer  security  breaches  and  be
subject  to  malicious  intent  or  cyberattack,  which  could  result  in  a  material  disruption  of  its  product  development  programs  and  in  its
operations in general.

The Company has implemented a security policy that is intended to secure its data against impermissible access and to preserve the integrity and
confidentiality of the data. To monitor these aspects, the Company set up a dedicated governance structure. See "Item 16K.—Cybersecurity."
Despite the implementation of such processes and measures, Innate's internal computer systems and those of its third-party contractors and
consultants are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war, telecommunication and
electrical failures and other sources. Moreover, part of the Company's information system is “cloud”-based and thus is not fully under its control.

In addition, Innate's research and development facility and headquarters in Luminy, France, is located in an area that may be more susceptible to
wildfires. If Innate's facility or computer systems are damaged by fire despite the fire prevention and data archiving measures it has put in place,
it could suffer financial losses and delays in its operations.

If such an event were to occur and cause interruptions in Innate's operations, it could result in a material disruption of its programs and more
generally  of  its  operations.  For  example,  the  loss  of  clinical  study  data  for  Innate's  product  candidates  could  result  in  delays  in  its  regulatory
approval  efforts  and  significantly  increase  its  costs  to  recover  or  reproduce  the  lost  data. To  the  extent  that  any  disruption  or  security  breach
results  in  a  loss  of  or  damage  to  Innate's  data  or  applications  or  other  data  or  applications  relating  to  its  technology  or  product  candidates  or
inappropriate disclosure of confidential or proprietary information, it could incur liabilities, including penalties under data privacy laws such as
the  GDPR  and  other  regulations,  and  the  further  development  of  its  product  candidates  could  be  delayed.  Even  if  the  Company  has  not
experienced  any  cyber  breach  to  date,  should  any  of  these  risks  materialize,  this  could  have  a  material  adverse  effect  on  Innate's  business,
prospects, financial condition and results of operations.

The Company has subscribed to insurance covering "cyber" and fraud. This insurance may be insufficient with regard to the level of financial,
legal, operational and reputational impacts that could arise from a disruption or a break of the Company information systems.

The Company may encounter difficulties in managing the Company development and support changes in its strategy, which could disrupt its
operations.

The  opportunities  taken,  the  decisions  made,  the  successes  and  failures  of  Innate's  research  and  development  programs  and  its  operations  in
general can have significant impacts on its workforce and the scope of its operations.

Potential rapid changes such as a strong growth in the Company's headcount or significant organizational changes aiming at supporting strategic
evolutions, may lead to a deterioration in working conditions and the leave of employees, which could lead to a loss of knowledge and expertise,
a decrease in the performance of Innate's operations and therefore a reduced level of achievement of its objectives.

For example, in December 2020, the decision of returning Lumoxiti commercial rights to AstraZeneca was followed by an immediate reduction
of  Innate's  commercial  operations  and  headcounts  in  the  United  States.  Although  the  Company  gained  some  experience  in  the  late  stage
development and marketing and commercialization of pharmaceutical products, such experience was short and may not have resulted in a

46

sufficient acquisition of skills to anticipate and tackle the marketing and commercialization of Innate's other drug candidates.

In addition, in order to support the development of the Company and changes in strategy, the Company must continue to implement and improve
its  management  and  operational  and  financial  systems,  adapt  its  facilities  and  recruit  and  train  qualified  personnel.  Due  to  Innate's  limited
financial  resources,  it  may  not  be  able  to  effectively  manage  the  development  of  Innate's  business,  which  could  result  in  weaknesses  in  its
infrastructure,  operational  errors,  loss  of  business  opportunities,  loss  of  employees  and  reduced  productivity  of  remaining  employees.  The
Company may also experience difficulties in recruiting, training and retaining additional qualified personnel, particularly in key positions. Added
to this is the fact that the Company is located in Marseille and is competing with other locations that potential recruits may find more attractive.

If  the  Company  were  to  acquire  assets  or  companies,  the  success  of  such  an  acquisition  would  depend  on  its  capacity  to  carry  out  such
acquisitions  and  to  integrate  such  assets  or  companies  into  its  existing  operations.  The  implementation  of  such  a  strategy  could  impose
significant constraints, including:

•

•

•

human resources: recruiting, integrating, training, managing, motivating and retaining a growing number of employees;

financial and management system resources: identification and management of appropriate financing and management of its financial
reporting systems; and

infrastructure: expansion or transfer of its laboratories or the development of its information technology system.

If the Company is unable to manage such changes or has difficulty integrating any acquisitions, it could have a material adverse effect on its
business, prospects, financial condition and results of operations.

The Company relies on certain independent organizations, partners, advisors and consultants to provide certain services and needs to hire
new employees and expand its use of service providers.

As of December 31, 2024, the Company had 181 employees. As Innate's development plans and strategies develop, Innate may need additional
managerial, operational, marketing, financial and other personnel.

The Company currently relies, and for the foreseeable future will continue to rely, in part on certain independent organizations, partners, advisors
and consultants to provide certain services. There can be no assurance that the services of these independent organizations, partners, advisors and
consultants will continue to be available to Innate on a timely basis when needed, or that Innate can find qualified replacements. In addition, if
Innate Pharma is unable to effectively manage its outsourced activities or if the quality or accuracy of the services provided by consultants is
compromised for any reason, its clinical trials may be extended, delayed or terminated, and it may not be able to obtain regulatory approval of its
product candidates or otherwise advance its business. There can be no assurance that Innate will be able to manage its existing consultants or
find other competent outside contractors and consultants on economically reasonable terms, if at all.

If  the  Company  is  not  able  to  effectively  expand  its  organization  by  hiring  new  employees  and  expanding  its  groups  of  consultants  and
contractors, it may not be able to successfully implement the tasks necessary to further develop and commercialize its product candidates and,
accordingly, may not achieve its research, development and commercialization goals.

47

The  Company  depends  on  qualified  management  personnel,  and  its  business  could  be  harmed  if  Innate  loses  key  personnel  and  cannot
attract new personnel.

Innate's  ability  to  retain  key  persons  in  its  organization  and  to  recruit  qualified  personnel  is  crucial  for  its  success.  In  particular,  its  success
depends heavily on its ability to retain key people in its organization, including key scientific and medical personnel.

Should the Company be unable to retain the individuals who form its team of key managers and key scientific advisors, it could have a material
adverse  effect  on  its  business  and  development  and  could  consequently  affect  its  business,  prospects,  financial  condition  and  results  of
operations.

Innate  will  need  to  recruit  qualified  scientific  and  medical  personnel  to  carry  out  its  clinical  studies  and  expand  into  new  areas  that  require
specialized skills, such as regulatory matters, marketing and manufacturing. Innate competes with other companies, research organizations and
academic institutions in recruiting and retaining highly qualified scientific, technical and management personnel. Competition for such personnel
is very intense in the biopharmaceutical field, and there can be no assurance that the Company will be successful in attracting or retaining such
personnel, and the failure to do so could harm its operations and its growth prospects. Should any of these risks materialize, this could have a
material adverse effect on Innate's business, prospects, financial condition and results of operations.

Innate's Research and Development facility and Headquarters in Luminy, France, are exposed to forest fires.

The Company's Research and Development facility and Headquarters in Luminy, France, are exposed to forest fires. Luminy is an area on the
outskirts of Marseille, composed in part of undeveloped hills covered with shrubs and pine trees. It is also located next to a natural park entirely
covered by the same type of Mediterranean vegetation. Summers are hot and dry, and this type of vegetation is prone to forest fires.

In  order  to  prevent  the  risk  of  fire,  fire  prevention  measures  are  implemented,  such  as  pruning  shrubs  in  the  surrounding  green  areas  and
implementing  a  maintenance  plan  for  fire-fighting  equipment.  In  addition,  computer  data  backup  and  archiving  measures  are  implemented,
allowing the regularly backed-up data to be stored on the premises of a specialized service provider. In addition, rare biological material used by
the Company has been identified, duplicated and stored at other sites, at the premises of specialized service providers.

However,  these  measures  do  not  guarantee  that  a  forest  fire  would  not  damage  the  Company's  premises  in  Luminy,  which  would  result  in
financial losses, development delays of various durations or even the suspension of the Company's activities.

The Company may use hazardous chemicals and biological materials in its business, and any claims relating to improper handling, storage
or disposal of these materials could be time-consuming and costly.

Innate's research and development processes involve the controlled use of hazardous materials, including chemicals, biological and radioactive
materials. The Company cannot eliminate the risk of accidental contamination or discharge and any resultant injury from these materials. Innate
also handles genetically recombined material, genetically modified species and pathological biological samples. Consequently, in France and in
the  jurisdictions  where  the  Company  conducts  clinical  trials,  it  is  subject  to  environment  and  safety  laws  and  regulations  governing  the  use,
storage,  handling,  discharge  and  disposal  of  hazardous  materials,  including  chemical  and  biological  products  and  radioactive  materials.  The
Company  imposes  preventive  and  protective  measures  for  the  protection  of  its  workforce  and  waste  control  management  in  accordance  with
applicable laws, including part four of the French Labor Code, relating to occupational health and safety.

48

In  France,  the  Company  is  required  to  comply  with  a  number  of  national,  regional  and  local  legislative  or  regulatory  provisions  regarding
radiation  and  hazardous  materials,  including  specific  regulations  regarding  the  use,  handling  and  storage  of  radioactive  materials  and  the
potential exposure of employees to hazardous materials and radiation. Innate must also comply with French regulations concerning the use and
handling of genetically modified organisms (GMOs) in confined spaces.

If  Innate  fails  to  comply  with  applicable  regulations,  it  could  be  subject  to  fines  and  may  have  to  suspend  all  or  part  of  its  operations.
Compliance with environmental, health and safety regulations involves additional costs, and Innate Pharma may have to incur significant costs to
comply with future laws and regulations in relevant jurisdictions. Compliance with environmental laws and regulations could require Innate to
purchase  equipment,  modify  facilities  and  undertake  considerable  expenses. The  Company  could  be  liable  for  any  inadvertent  contamination,
injury or damage, which could negatively affect its business, although the Company has subscribed to an insurance policy covering certain risks
inherent to its business.

Product  liability  and  other  lawsuits  could  divert  Innate's  resources,  result  in  substantial  liabilities,  reduce  the  commercial  potential  of  its
product candidates and damage its reputation.

Given that the Company develops therapeutic products intended to be tested on humans and used to treat humans, the risk that Innate may be
sued  on  product  liability  claims  is  inherent  in  its  business.  Side  effects  of,  or  manufacturing  defects  in,  products  that  the  Company  develops
could result in the deterioration of a patient’s condition, injury or even death. For example, its liability could be sought by patients participating
in  the  clinical  trials  in  the  context  of  the  development  of  the  therapeutic  products  tested  and  unexpected  side  effects  resulting  from  the
administration of these products. Once a product is approved for sale and commercialized, the likelihood of product liability lawsuits increases.
Criminal or civil proceedings might be filed against Innate by patients, regulatory authorities, biopharmaceutical companies and any other third
party  using  or  marketing  Innate's  products.  These  actions  could  include  claims  resulting  from  acts  by  Innate's  partners,  licensees  and
subcontractors,  over  which  the  Company  has  little  or  no  control.  These  lawsuits  may  divert  Innate's  management  from  pursuing  its  business
strategy and may be costly to defend. In addition, if the Company is held liable in any of these lawsuits, it may incur substantial liabilities, may
be forced to limit or forgo further commercialization of the affected products and may suffer damage to its reputation.

Although the clinical study process is designed to identify and assess potential side effects, it is always possible that a drug, even after regulatory
approval, may exhibit unforeseen side effects. If any of Innate's product candidates were to cause adverse side effects during clinical studies or
after approval of the product candidate, the Company may be exposed to substantial liabilities. Physicians and patients may not comply with any
warnings that identify known potential adverse effects and patients who should not use Innate's product candidates.

The  Company  has  obtained  liability  insurance  coverage  for  each  of  its  clinical  studies  in  compliance  with  local  legislation  and  rules.  In  the
United States, Innate's aggregate insurance coverage for its ongoing clinical studies is limited to €10.0 million per year and in the aggregate.
Innate's  insurance  coverage  may  not  be  sufficient  to  cover  any  expenses  or  losses  the  Company  may  suffer.  Moreover,  insurance  coverage  is
becoming increasingly expensive, and, in the future, Innate Pharma may not be able to maintain insurance coverage at a reasonable cost or in
sufficient amounts to protect itself against losses due to liability. On occasion, large judgments have been awarded in class action lawsuits based
on drugs that had unanticipated side effects. The cost of any product liability litigation or other proceedings, even if resolved in Innate's favor,
could be substantial. A successful product liability claim, or series of claims, brought against Innate could cause Innate's share price to decline
and, if judgments exceed its insurance coverage, could decrease its cash and adversely affect its business.

49

To date, the Company is covered by a product liability insurance with a coverage amount of €10 million per year in the aggregate. If Innate is the
subject of a successful product liability claim that exceeds the limits of any insurance coverage Innate Pharma obtains, the Company would incur
substantial charges that would adversely affect its earnings and require the commitment of capital resources that might otherwise be available for
the development and commercial launch of its product programs. Should any of these risks materialize, this could have a material adverse effect
on Innate's business, prospects, financial condition and results of operations.

Innate Pharma's employees may engage in misconduct or other improper activities, including violating applicable regulatory standards and
requirements, engaging in insider trading or violating the terms of their confidentiality agreements, which could significantly harm Innate's
business.

The  Company  is  exposed  to  the  risk  of  employee  fraud  or  other  misconduct.  Misconduct  by  employees  could  include  intentional  failure  to
comply with legal requirements or the requirements of national authorities, the EMA, FDA and other government regulators; failure to provide
accurate information to applicable government authorities; failure to comply with fraud and abuse and other healthcare laws and regulations in
the United States, Europe and elsewhere; and failure to report financial information or data accurately or disclose unauthorized activities to us. In
particular,  sales,  marketing  and  business  arrangements  in  the  healthcare  industry  are  subject  to  extensive  laws  and  regulations  intended  to
prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations restrict or prohibit a wide range of
pricing,  discounting,  marketing  and  promotion,  sales  commission,  customer  incentive  programs  and  other  business  arrangements.  Employee
misconduct  could  also  involve  the  improper  use  of,  including  trading  on,  information  obtained  in  the  course  of  clinical  studies,  which  could
result in regulatory sanctions and serious harm to Innate's reputation. Innate has a Code of Ethics that applies to all employees and consultants,
and other policies and charters, but it is not always possible to identify and deter employee misconduct, and the precautions it takes to detect and
prevent  this  activity  may  be  ineffective  in  controlling  unknown  or  unmanaged  risks  or  losses  or  in  protecting  Innate  from  governmental
investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations.

In  order  to  protect  its  proprietary  technology  and  processes,  the  Company  relies  in  part  on  confidentiality  agreements  with  its  partners,
employees,  consultants,  outside  scientific  collaborators  and  sponsored  researchers,  and  other  advisors.  These  agreements  may  not  effectively
prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential
information.  Costly  and  time-consuming  litigation  could  be  necessary  to  enforce  and  determine  the  scope  of  Innate's  proprietary  rights,  and
failure  to  obtain  or  maintain  trade  secret  protection  could  adversely  affect  its  competitive  business  position.  Should  any  of  these  risks
materialize, this could have a material adverse effect on Innate's business, prospects, financial condition and results of operations.

The Company may acquire businesses or products in the future, and Innate may not realize the benefits of such acquisitions.

Although  Innate's  current  strategy  involves  continuing  to  grow  its  business  internally,  the  Company  may  grow  externally  through  selective
acquisitions of complementary products and technologies, or of companies with such assets. If such acquisitions were to become necessary or
attractive  in  the  future,  the  Company  may  not  be  able  to  identify  appropriate  targets  or  make  acquisitions  under  satisfactory  conditions,  in
particular,  satisfactory  price  conditions.  In  addition,  Innate  may  be  unable  to  obtain  the  financing  for  these  acquisitions  under  favorable
conditions  and  could  be  led  to  finance  these  acquisitions  using  cash  that  could  be  allocated  to  other  purposes  in  the  context  of  existing
operations.  Innate  may  encounter  numerous  difficulties  in  developing,  manufacturing  and  marketing  any  new  products  resulting  from  an
acquisition that delays or prevents Innate from realizing their expected benefits or enhancing its

50

business. The Company cannot assure you that, following any such acquisition, the Company will achieve the expected synergies to justify the
transaction, which could have a material adverse effect on Innate's business, financial conditions, earnings and prospects.

Climate  change  or  legal,  regulatory  or  market  measures  to  address  climate  change  may  negatively  affect  Innate's  business  and  results  of
operations.

Climate change presents risks to Innate's operations, including the potential for additional regulatory requirements and associated costs, and the
potential for more frequent and severe weather events and water availability challenges that may impact Innate's facilities and those of Innate's
suppliers. Natural disasters and extreme weather conditions, such as a hurricane, tornado, earthquake, wildfire or flooding, may pose physical
risks to Innate's facilities and disrupt the operation of Innate's supply chain.

Concern over climate change may also result in new or additional legal or regulatory requirements designed to reduce greenhouse gas emissions
and/or mitigate the effects of climate change on the environment. If such laws or regulations are more stringent than current legal or regulatory
obligations, the Company may experience disruption in or an increase in the costs associated with sourcing, manufacturing and distribution of
Innate's products, which may adversely affect Innate's business, results of operations or financial condition.

The current state of the world financial market and current economic conditions could have a material adverse impact on the Company's
business, financial conditions, results of operations and cash flows.

The  global  economy  is  facing  a  number  of  actual  and  potential  challenges,  including  the  military  conflict  between  Ukraine  and  Russia,  the
conflict in Israel and the Middle East region generally, and the banking crises or failures, such as the recent failures of Silicon Valley Bank and
other U.S. regional banks and the instability of certain European banks. If the conditions in the global economy remain uncertain or continue to
be volatile, or if they deteriorate, including as a result of the ongoing military conflict between Russia and Ukraine, the conflict in Israel, banking
crises or other geopolitical events, the Company's business, financial condition and results of operation may be materially adversely affected.

In addition, increases in inflation raise the Company's costs for labor, materials and services and other costs required to grow and operate its
business,  and  failure  to  secure  these  on  reasonable  terms  may  adversely  impact  its  financial  condition.  Increases  in  inflation,  along  with  the
uncertainties  surrounding  potential  future  pandemics,  ongoing  geopolitical  developments,  banking  crises  and  global  supply  chain  disruptions,
could potentially disrupt Innate's business and supply chain, and make it more difficult for Innate to obtain additional funds given the lack of
liquidity  in  capital  markets  that  these  events  could  cause.  Such  risks  and  disruptions  may  also  negatively  impact  Innate's  supply  chain,
manufacturing  arrangements,  preclinical  studies  and  clinical  trials,  which  could  have  a  materially  adverse  impact  on  its  results  of  operations,
financial condition and prospects. The extent and duration of the current economic conditions and resulting market disruptions are impossible to
predict but could be substantial. Any such disruptions may also magnify the impact of other risks described in this Annual Report on Form 20-F.
See “Risk Factors—The Company's future growth depends, in part, on its ability to penetrate multiple markets, in which the Company would be
subject to additional regulatory burdens and other political, social and geopolitical risks and uncertainties.”

Risks Related to Intellectual Property Rights

Its  ability  to  compete  may  be  adversely  affected  if  the  Company  does  not  adequately  obtain,  maintain,  protect  and  enforce  Innate's
intellectual property or proprietary rights, or if the scope of intellectual property protection the Company obtains is not sufficiently broad.

Innate's success depends, in large part, on its ability to obtain and maintain patent and other intellectual property protection in the United States
and other countries with respect to Innate's product candidates. However, the Company may not be able to obtain, maintain or enforce Innate's
patents and other intellectual property rights, which could affect its ability to compete effectively. For example, the Company cannot guarantee:

•

•

•

•

•

•

that the Company will file all necessary or desirable patent applications or that the Company will obtain the patents that the Company
has applied for and that are under review;

that the Company will be able to develop new patentable product candidates or technologies or obtain patents to protect such new
product candidates or technologies;

that the Company or its licensing or collaboration partners were the first to make the product candidates or technologies covered by
the issued patents or pending patent applications that the Company licenses or owns;

that  the  Company  will  be  able  to  obtain  sufficient  rights  to  all  necessary  or  desirable  patents  or  other  intellectual  property  rights,
whether at all or on reasonable terms;

that  the  scope  of  any  issued  patents  that  the  Company  owns  or  licenses  will  be  broad  enough  to  protect  its  product  candidates  or
effectively prevent others from commercializing competitive technologies and product candidates; and

that there is no risk of its owned and licensed patents being challenged, invalidated or circumvented by a third party.

The patent prosecution process is expensive, time-consuming and complex, and Innate may not be able to file, prosecute, maintain, enforce or
license all necessary or desirable patent applications at a reasonable cost or in a timely manner. For example, the Company does not intend to
systematically file, maintain, prosecute and defend patents on its product candidates in all countries. Consequently, Innate may not be able to
prevent third parties from exploiting products that are the same as or similar to its products and product candidates in countries in which it does
not obtain patent protection, or from selling or importing such products in and into the countries in which it does have patent protection. It is also
possible  that  the  Company  will  fail  to  identify  patentable  aspects  of  its  research  and  development  output  in  time  to  obtain  patent  protection.
Although the Company enters into confidentiality agreements with parties who have access to confidential or patentable aspects of its research
and development output, such as its employees, consultants, CROs, outside scientific collaborators, sponsored researchers and other advisors,
any of these parties may breach the agreements and disclose such output before a patent application is filed, thereby jeopardizing its ability to
seek patent protection. Given the amount of time required for the development, testing and regulatory review of new product candidates, patents
protecting  such  candidates  might  expire  before  or  shortly  after  such  candidates  are  commercialized. As  a  result,  Innate's  intellectual  property
may not provide Innate with sufficient rights to exclude others from commercializing product candidates similar or identical to Innate's products.
In  addition,  in  some  circumstances,  the  Company  may  not  have  the  right  to  control  the  preparation,  filing,  prosecution,  maintenance,
enforcement and defense of patents and patent applications covering technology that the Company licenses to or from third parties. For example,
pursuant to its license agreement with AstraZeneca for monalizumab, AstraZeneca retains

52

control of such activities for certain patents that the Company licenses to it under the agreement and patents that arise under the collaboration.
Innate cannot be certain that these patents and patent applications will be prepared, filed, prosecuted, maintained, enforced and defended in a
manner consistent with the best interest of its business. If any third party that controls Innate's patents and patent applications fails to maintain
Innate's  patents  or  such  third  party  loses  rights  to  Innate's  patents  or  patent  applications,  Innate's  rights  to  those  patents  and  underlying
technology may be reduced or eliminated and the Company's right to develop and commercialize its product candidates that are subject to such
rights could be adversely affected.

Moreover, some of Innate's patents and patent applications are, and may in the future be, co-owned with third parties. If the Company is unable
to obtain an exclusive license to any such third-party co-owners’ interest in such patents or patent applications, such co-owners may be able to
license their rights to other third parties, including its competitors, and its competitors could market competing products and technology. Innate
may also need the cooperation of any such co-owners of its patents in order to enforce such patents against third parties, and such cooperation
may not be provided to us.

The coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted after
issuance.  The  issuance  of  a  patent  is  not  conclusive  as  to  its  inventorship,  scope,  validity  or  enforceability.  Even  if  patent  applications  the
Company licenses or owns currently or in the future issue as patents, they may not issue in a form that will provide Innate with any meaningful
protection, prevent competitors or other third parties from circumventing its patents by developing similar or alternative technologies or products
in  a  non-infringing  manner,  or  otherwise  provide  Innate  with  any  competitive  advantage.  Challenges  from  competitors  or  other  third  parties
could  reduce  the  scope  of  Innate's  patents  or  render  them  invalid  or  unenforceable,  which  could  limit  its  ability  to  stop  others  from  using  or
commercializing  similar  or  identical  technology  and  product  candidates,  or  limit  the  duration  of  the  patent  protection  for  Innate's  product
candidates. The legal proceedings that the Company may then have to enter into in order to enforce and defend its intellectual property could be
very costly and could distract its management and other personnel from their normal responsibilities, notably in the case of lawsuits in the United
States. The probability of disputes arising over Innate's intellectual property will increase progressively as patents are granted and as the value
and appeal of the inventions protected by these patents are confirmed. The occurrence of any of these events concerning any of Innate's patents
or intellectual property rights could have a material adverse effect on its business, prospects, financial condition and results of operations. These
risks are even higher for the Company, because of its limited financial and human resources.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions,
and  has  been  the  subject  of  much  litigation  in  recent  years. As  a  result,  the  issuance,  scope,  validity,  enforceability  and  commercial  value  of
Innate's patent rights are highly uncertain. The Company's pending and future patent applications may not result in patents being issued which
protect  its  technology  or  product  candidates  or  which  effectively  prevent  others  from  commercializing  competitive  technologies  and  product
candidates. Furthermore, its owned and in-licensed patents may be subject to a reservation of rights by one or more third parties. For example,
the research resulting in certain of its owned and licensed patent rights and technology was funded in part by the U.S. government. As a result,
the government may have certain rights, or march-in rights, to such patent rights and technology. When new technologies are developed with
government funding, the government generally obtains certain rights in any resulting patents, including a non-exclusive license authorizing the
government  to  use  the  invention  for  non-commercial  purposes.  These  rights  may  permit  the  government  to  disclose  Innate's  confidential
information  to  third  parties  and  to  exercise  march-in  rights  to  use  or  allow  third  parties  to  use  its  licensed  technology.  The  government  can
exercise its march-in rights if it determines that action is necessary because the Company failed to achieve practical

53

application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal
regulations  or  to  give  preference  to  U.S.  industry.  In  addition,  Innate's  rights  in  such  inventions  may  be  subject  to  certain  requirements  to
manufacture  products  embodying  such  inventions  in  the  United  States.  Any  exercise  by  the  government  of  such  rights  could  harm  Innate
Pharma's competitive position, business, financial condition, results of operations and prospects.

Third  parties  may  allege  that  the  Company  or  its  partners  infringe,  misappropriate  or  otherwise  violate  such  third  parties’  intellectual
property rights, which could prevent or delay its development efforts, stop Innate from commercializing its product candidates, or increase
the costs of commercializing its product candidates.

The  Company's  commercial  success  depends  on  its  ability  and  the  ability  of  its  partners  to  develop,  manufacture,  market  and  sell  its  product
candidates,  and  use  its  proprietary  technologies,  without  infringing,  misappropriating  or  otherwise  violating  any  intellectual  property  or
proprietary rights of third parties. The field of biopharmaceuticals involves significant patent and other intellectual property litigation, which can
be highly uncertain and involve complex legal and factual questions. The interpretation and breadth of claims allowed in some patents covering
biopharmaceutical compositions also may be uncertain and difficult to determine.

Innate  may  not  be  aware  of  all  third-party  intellectual  property  rights  potentially  relating  to  its  product  candidates.  In  general,  in  the  United
States patent applications are not published until 18 months after filing or, in some cases, not at all. Therefore, the Company cannot be sure that
it was the first to make the inventions claimed in any owned or licensed patents or pending patent applications, or that it was the first to file for
patent protection for such inventions. If the Company was not the first to invent such inventions or first to file any patent or patent application
for such inventions, it may be unable to make use of such inventions in connection with its products. Innate may need to obtain licenses from
third parties (which may not be available under commercially reasonable terms, or at all), delay the launch of product candidates or cease the
production and sale of certain product candidates or develop alternative technologies that are the subject of such patents or patent applications,
any of which could have a material adverse effect on its business, prospects, financial condition and results of operations.

Third parties may allege that Innate or its partners infringe, misappropriate or otherwise violate any such third party’s patents or other intellectual
property rights and assert infringement claims against us, regardless of their merit. A court of competent jurisdiction could hold that these third-
party  patents  are  valid,  enforceable  and  infringed,  which  could  materially  and  adversely  affect  Innate's  ability  to  commercialize  any  product
candidates it may develop and any other product candidates or technologies covered by the asserted third-party patents. In order to successfully
challenge the validity of any such U.S. patent in federal court, Innate would need to overcome a presumption of validity. As this burden is a high
one requiring Innate to present clear and convincing evidence as to the invalidity of any such U.S. patent claim, there is no assurance that a court
of competent jurisdiction would invalidate the claims of any such U.S. patent. If the Company is found to infringe a third party’s intellectual
property rights, and the Company is unsuccessful in demonstrating that such rights are invalid or unenforceable, the Company could be required
to:

•

•

•

bear the potentially significant costs of proceedings brought against us;

pay  damages,  which  may  include  treble  damages  and  attorney’s  fees  if  the  Company  is  found  to  have  willfully  infringed  a  third
party’s patent rights;

cease developing, manufacturing and commercializing the infringing technology or product candidates; and

54

•

acquire a license to such third-party intellectual property rights, which may not be available on commercially reasonable terms, or at
all,  and  may  be  non-exclusive,  thereby  giving  the  Company's  competitors  and  other  third  parties  access  to  the  same  technologies
licensed to us.

Even if resolved in Innate's favor, litigation or other intellectual property proceedings may cause Innate to incur significant expenses and could
distract its management and other personnel from their normal responsibilities. For example, Orega Biotech claims joint ownership of certain
patents  relating  to  IPH5201,  which  the  Company  disputed. As  a  result  of  a  decision  rendered  by  the  arbitral  tribunal  in  December  2021,  the
Company will be required to pay a low-teen percentage to Orega Biotech on a going forward basis of sub-licensing revenues received by the
Company pursuant to its agreement with AstraZeneca regarding IPH5201, and the Company may be obligated to pay Orega Biotech additional
amounts  upon  the  achievement  of  development  and  regulatory  milestones  under  such  agreement.  See  Note  6  to  the  consolidated  financial
statements included under "Item 18. Financial Statements" of this Annual Report. In addition, there could be public announcements of the results
of hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it
could have a material adverse effect on the price of Innate's ordinary shares or ADSs. The Company may not have sufficient financial or other
resources to adequately conduct such litigation or proceedings. Some of Innate's competitors may be able to sustain the costs of such litigation or
proceedings more effectively than Innate can because of their greater financial resources and more mature and developed intellectual property
portfolios.  Should  one  or  more  of  the  foregoing  risks  materialize,  this  could  have  a  material  adverse  effect  on  Innate's  reputation,  business,
prospects, financial condition and results of operations.

Its patents could be found invalid or unenforceable if challenged, and the Company may not be able to protect its intellectual property.

Innate's and its licensors’ patents and patent applications, if issued, may be challenged, invalidated or circumvented by third parties. U.S. patents
and patent applications may also be subject to interference proceedings, re-examination proceedings, derivation proceedings, post-grant review
or  inter  partes  review  in  the  United  States  Patent  and Trademark  Office  (USPTO),  challenging  Innate's  or  its  licensors’  patent  rights.  Foreign
patents may be subject also to opposition or comparable proceedings in the corresponding foreign patent office. For example, a third party filed
an  opposition  in  the  European  Patent  Office  (EPO)  challenging  one  of  the  Company's  European  patents  with  claims  directed  to  use  of  anti-
NKG2A  antibodies  for  treating  cancer  in  an  individual  having  progressive  disease  following  treatment  with  an  antibody  that  neutralizes  the
inhibitory activity of PD-1. The EPO issued a decision maintaining the Company's patent as granted, however the third party has appealed such
decision.  Third-party  oppositions  have  also  been  filed  challenging  two  of  the  Company's  in-licensed  European  patents  directed  to  CD39
technology.  One  of  these  oppositions  has  not  yet  resulted  in  a  first-instance  decision  in  the  EPO,  while  the  other  opposition  resulted  in  the
revocation  of  the  patents  directed  to  CD39  technology,  which  revocation  was  appealed  by  Innate's  licensor(s).  All  of  the  aforementioned
oppositions are currently pending.

In addition, the Company may allege that third parties infringe Innate's or its licensors’ patents, and the defendant could counterclaim that such
patents are invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or unenforceability are
commonplace.  Grounds  for  a  validity  challenge  could  be  an  alleged  failure  to  meet  any  of  several  statutory  requirements,  including  lack  of
novelty,  obviousness  or  non-enablement.  Grounds  for  an  unenforceability  assertion  could  be  an  allegation  that  someone  connected  with
prosecution  of  the  patent  withheld  relevant  information  from  the  USPTO,  or  made  a  misleading  statement,  during  prosecution. The  outcome
following legal assertions of invalidity and unenforceability is unpredictable. With respect to the validity question, for example, Innate cannot be
certain  that  there  is  no  invalidating  prior  art  of  which  the  Company  or  its  licensing  partners  and  the  patent  examiner  were  unaware  during
prosecution.

55

Any  such  patent  litigation  or  proceeding  could  result  in  the  loss  of  Innate  or  its  licensors’  patents,  denial  of  Innate's  or  its  licensors’  patent
applications  or  loss  or  reduction  in  the  scope  of  one  or  more  of  the  claims  of  such  patents  or  patent  applications. Accordingly,  Innate's  or  its
licensors’ rights under any issued patents may not provide Innate with sufficient protection against competitive product candidates or processes;
Innate could become unable to manufacture or commercialize its product candidates without infringing third-party patent rights; and the duration
of  the  patent  protection  of  its  product  candidates  could  be  limited.  Furthermore,  because  of  the  substantial  amount  of  discovery  required  in
connection with intellectual property litigation, there is a risk that some of Innate's confidential information could be compromised by disclosure
during this type of litigation. Even if the Company is successful, such litigation or proceedings may be costly and may distract its management
and other personnel from their normal responsibilities. Any of the foregoing could have a material adverse effect on Innate's business, prospects,
financial condition and results of operations.

Obtaining  and  maintaining  the  Company's  patent  protection  depends  on  compliance  with  various  procedural,  document  submission,  fee
payment and other requirements imposed by government patent agencies, and its patent protection could be reduced or eliminated for non-
compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other government fees on patents and/or applications will be due to be paid to
the USPTO, and various government patent agencies outside of the United States over the lifetime of Innate's owned and licensed patents and/or
patent applications and any patent rights the Company may own in the future. In certain circumstances, Innate Pharma may rely on its licensing
partners  to  pay  these  fees.  The  USPTO  and  various  foreign  patent  agencies  require  compliance  with  several  procedural,  documentary,  fee
payment and other similar provisions during the patent application process. In many cases, an inadvertent lapse can be cured by payment of a
late  fee  or  by  other  means  in  accordance  with  the  applicable  rules.  There  are  situations,  however,  in  which  non-compliance  can  result  in
abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such
an event, potential competitors might be able to enter the market with similar or identical products or technology, which could have a material
adverse effect on Innate's business, prospects, financial condition and results of operations.

Developments in patent law could have a negative impact on the Company's business.

Changes in either the patent laws or interpretation of the patent laws could increase the uncertainties and costs surrounding the prosecution of
patent applications and the enforcement or defense of issued patents. For example, from time to time, the U.S. Congress, the USPTO or similar
foreign authorities may change the standards of patentability, and any such changes could have a negative impact on Innate's business. Therefore,
we cannot be certain that we will obtain adequate patent protection for new products in important markets or that such protections, once granted,
will last as long as originally anticipated. In addition, in an infringement suit against a third party, we may not prevail, and the decision rendered
may not conclude that our patent or other proprietary rights are valid, enforceable, or infringed. Even in cases where we ultimately prevail in an
infringement claim, legal remedies available for harm caused to us by infringing products may be inadequate to make us whole. If we lose patent
protection because of an adverse court decision or a settlement, we face the risk that government and private third-party payers and purchasers of
pharmaceutical products may claim damages alleging they have over-reimbursed or overpaid for a drug.

Trademarks

In addition, changes to or different interpretations of patent laws in the United States and other countries may permit others to use Innate's or its
partners’ discoveries or to develop and commercialize Innate's technology and product candidates without providing any compensation to Innate,
or may limit the

56

number of patents or claims it can obtain. The patent positions of companies in the biotechnology and pharmaceutical market are particularly
uncertain.  Recent  U.S.  Supreme  Court  rulings  have  narrowed  the  scope  of  U.S.  patent  protection  available  in  certain  circumstances  and
weakened the rights of patent owners in certain situations. This combination of events has created uncertainty with respect to the validity and
enforceability of patents, once obtained. Depending on future actions by the U.S. Congress, the federal courts, and the USPTO, as well as similar
bodies  in  other  countries,  the  laws  and  regulations  governing  patents  could  change  in  unpredictable  ways  that  could  have  a  material  adverse
effect on Innate's existing patent portfolio and its ability to protect and enforce its intellectual property in the future, which could have a material
adverse effect on its business, prospects, financial condition and results of operations.

If the Company does not obtain protection under the Hatch-Waxman Amendments and similar non-U.S. legislation for extending the term of
patents covering each of its product candidates, its business may be materially harmed.

Depending  upon  the  timing,  duration  and  conditions  of  FDA  marketing  authorization  of  Innate's  product  candidates,  one  or  more  of  its  U.S.
patents  may  be  eligible  for  limited  patent  term  extension  under  the  Drug  Price  Competition  and  Patent Term  Restoration Act  of  1984,  or  the
Hatch-Waxman Amendments, and similar legislation in the European Union. The Hatch-Waxman Amendments permit a patent term extension of
up to five years for a patent covering an approved product as compensation for effective patent term lost during product development and the
FDA regulatory review process. However, the Company may not receive an extension if the Company fails to apply within applicable deadlines,
fails  to  apply  prior  to  expiration  of  relevant  patents,  fails  to  exercise  due  diligence  during  the  testing  Phase  or  regulatory  review  process  or
otherwise fails to satisfy applicable requirements, and the Company may not prevail in any actions that it may bring under the Hatch-Waxman
amendments against generic manufacturers or others. Moreover, the length of the extension could be less than what the Company requests. If the
Company  is  unable  to  obtain  patent  term  extension  or  the  term  of  any  such  extension  is  less  than  its  requests,  the  period  during  which  the
Company can enforce its patent rights for that product will be shortened, and its competitors may obtain approval to market competing products
sooner. As a result, Innate's revenue from an applicable product could be reduced, which could have a material adverse effect on its business,
prospects, financial condition and results of operations.

The Company will not seek to protect its intellectual property rights in all jurisdictions throughout the world, and Innate may not be able to
adequately enforce its intellectual property rights in all jurisdictions where Innate Pharma seeks intellectual property protection.

Filing,  maintaining,  prosecuting  and  defending  patents  on  Innate's  product  candidates  in  all  countries  and  jurisdictions  throughout  the  world
would be prohibitively expensive, and its intellectual property rights in some countries outside the United States could be less extensive than
those in the United States. Consequently, the Company may not be able to prevent third parties from using its product candidates or technologies
in all countries outside the United States, or from selling or importing products made using its product candidates or technologies in and into the
United States or other jurisdictions. Competitors may use Innate's technologies in jurisdictions where Innate Pharma does not pursue and obtain
patent  protection  to  develop  their  own  products  and,  further,  may  export  otherwise  infringing  products  to  territories  where  the  Company  has
patent  protection,  and  enforcement  is  not  as  strong  as  that  in  the  United  States.  These  products  may  compete  with  Innate's  products,  and  its
patents or other intellectual property rights may not be effective or sufficient to prevent them from competing. Even if the Company pursues and
obtains issued patents in particular jurisdictions, its patent claims or other intellectual property rights may not be effective or sufficient to prevent
third parties from so competing.

In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as the federal and state laws in the
United States. Many companies have encountered significant

57

problems  in  protecting  and  defending  intellectual  property  rights  in  certain  foreign  jurisdictions.  The  legal  systems  of  some  countries,
particularly developing countries, do not favor the enforcement of patents and other intellectual property protection, especially those relating to
biopharmaceuticals or biotechnologies. This could make it difficult for Innate Pharma to stop the infringement of its patents, if obtained, or the
misappropriation or other violation of its other intellectual property rights. For example, many foreign countries have compulsory licensing laws
under  which  a  patent  owner  must  grant  licenses  to  third  parties.  In  addition,  many  countries  limit  the  enforceability  of  patents  against  third
parties,  including  government  agencies  or  government  contractors.  In  these  countries,  patents  may  provide  limited  or  no  benefit.  Patent
protection  must  ultimately  be  sought  on  a  country-by-country  basis,  which  is  an  expensive  and  time-consuming  process  with  uncertain
outcomes. Accordingly, the Company may choose not to seek patent protection in certain countries, and the Company will not have the benefit of
patent protection in such countries.

Proceedings to enforce Innate's patent rights in foreign jurisdictions could result in substantial costs and divert its efforts and attention from other
aspects of its business, could put its patents at risk of being invalidated or interpreted narrowly, could put its patent applications at risk of not
issuing and could provoke third parties to assert claims against us. The Company may not prevail in any lawsuits that the Company initiates, and
the  damages  or  other  remedies  awarded,  if  any,  may  not  be  commercially  meaningful.  In  addition,  changes  in  the  law  and  legal  decisions  by
courts in the United States and other countries may affect Innate's ability to obtain adequate protection for its technology and the enforcement of
its intellectual property. Accordingly, Innate's efforts to enforce its intellectual property rights around the world may be inadequate to obtain a
significant commercial advantage from the intellectual property that the Company develops or licenses. Should any of these risks materialize,
this could have a material adverse effect on Innate's business, prospects, financial condition and results of operations.

Third parties may assert ownership or commercial rights to products, product candidates or technologies that Innate develops.

Third parties have made, and may in the future make, claims challenging the inventorship or ownership of Innate's intellectual property, which
may result in the imposition of additional obligations on us, such as development, royalty and milestone payments. Innate has written agreements
with partners or other third parties that provide for the ownership of intellectual property arising from its collaborations and its other work with
such third parties. These agreements provide that the Company must negotiate certain commercial rights with partners and other third parties
with respect to joint inventions or inventions made by its partners or such third parties that arise from the results of the collaboration or other
work  with  such  third  parties.  In  some  instances,  there  may  not  be  adequate  written  provisions  to  address  clearly  the  resolution  of  intellectual
property  rights  that  may  arise  under  Innate's  agreements.  If  the  Company  cannot  successfully  negotiate  sufficient  ownership  and  commercial
rights  to  the  inventions  that  result  from  its  use  of  a  third  party’s  materials  where  required,  or  if  disputes  otherwise  arise  with  respect  to  the
intellectual  property  developed  with  the  use  of  a  third  party’s  samples,  the  Company  may  be  limited  in  its  ability  to  capitalize  on  the  market
potential  of  these  inventions.  In  addition,  the  Company  may  face  claims  by  third  parties  that  its  agreements  with  employees,  contractors  or
consultants obligating them to assign intellectual property to itself are ineffective, or in conflict with prior or competing contractual obligations
of assignment, which could result in ownership disputes regarding intellectual property the Company has developed or will develop and interfere
with its ability to capture the commercial value of such inventions. The Company also may be unsuccessful in executing assignment agreements
with each party who, in fact, conceives or develops intellectual property that the Company regards as its own, or such agreements might not be
self-executing or might be breached.

Litigation may be necessary to resolve an ownership dispute, and if the Company is not successful, Innate may be precluded from using certain
intellectual property, may lose its exclusive rights in such

58

intellectual  property  or  may  be  required  to  acquire  a  license  to  such  intellectual  property,  which  may  not  be  available  on  commercially
reasonable terms or at all. Any of the foregoing could have a material adverse impact on Innate's business.

If  the  Company  fails  to  comply  with  its  obligations  under  license  or  technology  agreements  with  third  parties,  Innate  Pharma  could  lose
license rights that are critical to its business, and the Company may not be successful in obtaining necessary intellectual property rights.

Innate  licenses  intellectual  property  from  third  parties  that  is  critical  to  its  business  through  license  agreements,  including  but  not  limited  to
licenses  related  to  the  manufacture,  composition,  use  and  sale  of  its  product  candidates,  and  in  the  future  Innate  may  enter  into  additional
agreements that provide it with licenses to valuable intellectual property or technology. For example, Innate depends on its license agreement
with Novo Nordisk A/S for the development and commercialization of monalizumab. Innate's license agreements impose various obligations on
us, which may include development, royalty and milestone payments. If the Company fails to comply with any of these obligations, its licensors
may have the right to terminate the agreements. If its license agreements with AstraZeneca or Novo Nordisk A/S or any other current or future
licensors terminate, the Company would lose valuable rights and may be required to cease its development, manufacture or commercialization of
its product candidates, including monalizumab. In addition, its business would suffer if its licensors fail to abide by the terms of the agreements,
if  its  licensors  fail  to  prevent  infringement  by  third  parties  or  if  the  licensed  patents  or  other  rights  are  found  to  be  invalid  or  unenforceable.
Should any of these risks materialize, this could have a material adverse effect on Innate's business, prospects, financial condition and results of
operations.

In addition, disputes may arise regarding intellectual property subject to a license agreement, including:

•

•

•

•

•

the scope of rights granted under the license agreement and other interpretation-related issues;

the extent to which its technology and processes infringe on intellectual property of the counterparty that is not subject to the license
agreement;

Innate's diligence obligations under the license agreement and what activities satisfy those diligence obligations;

the  inventorship  or  ownership  of  inventions  and  know-how  resulting  from  the  joint  creation  or  use  of  intellectual  property  by  its
counterparties and us; and

the priority of invention of patented technology.

The agreements under which the Company currently licenses intellectual property from third parties are complex, and certain provisions in such
agreements  may  be  susceptible  to  multiple  interpretations.  The  resolution  of  any  contract  dispute  that  may  arise  could  narrow  what  Innate
believes to be the scope of its rights to the relevant intellectual property, or modify in a manner adverse to Innate what the Company believes to
be Innate's or its counterpart’s financial or other obligations under the relevant agreement, any of which could have a material adverse effect on
its business, financial condition, results of operations and prospects. If disputes over intellectual property that Innate Pharma has licensed prevent
or impair its ability to maintain its current license agreement on acceptable terms, the Company may be unable to unsuccessfully develop and
commercialize the affected product candidates.

Additionally,  the  growth  of  Innate's  business  may  depend,  in  part,  on  its  ability  to  acquire,  in-license  or  use  proprietary  rights  held  by  third
parties. The Company may be unable to acquire or in-license intellectual property rights from third parties that Innate identifies as necessary for
its product candidates on reasonable terms or at all. The licensing or acquisition of third-party intellectual property rights is a competitive area,
and several more established companies may pursue strategies to license or acquire third-party intellectual property rights that the Company may
consider attractive. These established

59

companies  may  have  a  competitive  advantage  over  Innate  due  to  their  size,  capital  resources  and  greater  clinical  development  and
commercialization capabilities. In addition, companies that perceive Innate to be a competitor may be unwilling to assign or license rights to us.
Innate also may be unable to license or acquire third-party intellectual property rights on terms that would allow Innate to make an appropriate
return on its investment.

As part of its business, the Company collaborates with non-profit and academic institutions to accelerate its preclinical research or development
under  agreements  with  these  institutions.  Typically,  these  institutions  provide  Innate  with  an  option  to  negotiate  a  license  to  any  of  the
institution’s or its employees’ rights in technology resulting from the collaboration. Regardless of such option, Innate may be unable to negotiate
a license within the specified timeframe or under terms that are acceptable to us. If the Company is unable to do so, the institution may offer the
intellectual property rights to other parties, potentially blocking its ability to pursue its applicable development or commercialization program. If
Innate  Pharma  is  unable  to  successfully  obtain  rights  to  required  third-party  intellectual  property  rights  or  maintain  the  existing  intellectual
property  rights  Innate  has,  Innate  may  have  to  abandon  the  development  and  commercialization  of  the  relevant  program,  and  its  business,
financial conditions, results of operations and prospects could be adversely affected.

Third  parties  may  assert  that  Innate's  employees,  consultants  or  independent  contractors  have  wrongfully  used  or  disclosed  confidential
information or misappropriated trade secrets of their current or former employers.

The  Company  employs  individuals  who  are  currently,  or  were  previously,  employed  at  universities  or  other  biotechnology  or  pharmaceutical
companies, including its competitors or potential competitors. Although Innate tries to ensure that its employees, consultants and independent
contractors do not use the proprietary information or know-how of others in their work for Innate, and no such claims against it are currently
pending, Innate may be subject to claims that Innate or its employees, consultants or independent contractors have used or disclosed intellectual
property,  including  trade  secrets  or  other  proprietary  information,  of  any  such  individual’s  current  or  former  employer  or  other  third  parties.
Litigation may be necessary to defend against these claims. If Innate fails in defending any such claims, in addition to paying monetary damages,
Innate may lose valuable intellectual property rights or personnel. Even if Innate is successful in defending against such claims, litigation could
result in substantial costs and be a distraction to its management and other employees. Should any of these risks materialize, this could have a
material adverse effect on Innate's business, prospects, financial condition and results of operations.

If the Company is unable to protect the confidentiality of its trade secrets, its business and competitive position could be materially harmed.

In addition to patent protection, because the Company operates in the highly technical field of biopharmaceutical drug development, it relies in
part on trade secret protection in order to protect its proprietary technology and processes. However, trade secrets are difficult to protect. The
Company seeks to protect its trade secrets, in part, by entering into confidentiality agreements with its employees, consultants, CROs, outside
scientific collaborators, sponsored researchers and other advisors. These agreements generally require that the other party keep confidential and
not disclose to third parties all confidential information developed by such party or made known to such party by Innate during the course of
such party’s relationship with us. However, Innate cannot guarantee that it has entered into such agreements with each party that may have or
have  had  access  to  its  trade  secrets  and  confidential  information,  and  these  agreements  may  be  breached,  and  Innate  may  not  have  adequate
remedies for any breach.

60

In  addition  to  contractual  measures,  the  Company  tries  to  protect  the  confidential  nature  of  its  proprietary  information  using  physical  and
technological security measures. Such measures may not, for example, in the case of misappropriation of a trade secret by an employee or third
party  with  authorized  access,  provide  adequate  protection  for  Innate's  proprietary  information.  Innate's  security  measures  may  not  prevent  an
employee or consultant from misappropriating its trade secrets and providing them to a competitor, and recourse it takes against such misconduct
may not provide an adequate remedy to protect its interests fully. Enforcing a claim that a party illegally disclosed or misappropriated a trade
secret can be difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, courts outside the United States may be
less  willing  to  protect  trade  secrets.  Moreover,  trade  secrets  may  be  independently  developed  by  others  in  a  manner  that  could  prevent  legal
recourse by Innate. If any of Innate's confidential or proprietary information, such as its trade secrets, were to be disclosed to or misappropriated
by a third party, or if any such information was independently developed by a third party, its competitive position could be materially harmed.

Innate's trade and technical secrets include:

•

•

•

•

certain  unpatented  technical  expertise  that  the  Company  believes  provides  itself  with  an  advantage  in  conducting  research  and
development work in its field;

certain scientific knowledge generated by the work the Company carries out;

certain information relating to the product candidates the Company is currently developing; and

certain information relating to the agreements signed between the Company and third parties.

The unauthorized disclosure or misappropriation of certain of these secrets could allow third parties to offer products or services to compete with
its or generally have a material adverse effect on Innate's business.

The structures put in place to protect Innate's trade and technical secrets do not constitute a guarantee that one or more of its trade and technical
secrets  will  not  be  disclosed  or  misappropriated.  The  agreements  or  other  arrangements  to  protect  the  Company's  trade  secrets  may  fail  to
provide  the  protection  sought,  or  may  be  breached,  or  its  trade  secrets  may  be  disclosed  to,  or  developed  independently  by,  its  competitors.
Should any of these risks materialize, this could have a material adverse effect on Innate's business, prospects, financial condition and results of
operations.

Unauthorized use of Innate's trademarks may generate confusion and result in costs and delays to the detriment of its marketing efforts.

Innate's trademarks are a key component of its identity and its products. Although the key components of its trademarks have been registered,
notably  in  France  and  the  United  States,  other  companies  in  the  pharmaceutical  sector  might  use  or  attempt  to  use  similar  trademarks  or
components  of  the  Company's  trademarks  and  thereby  create  confusion  in  the  minds  of  third  parties.  Innate's  registered  trademarks  may  be
challenged,  infringed,  circumvented  or  declared  generic  or  determined  to  be  infringing  on  other  marks.  In  addition,  there  could  be  potential
trademark  infringement  claims  brought  by  owners  of  other  trademarks  that  incorporate  variations  of  Innate's  registered  or  unregistered
trademarks.

In the event the Company develops trademarks for products that conflict with intellectual property rights of third parties, Innate would then have
to  redesign  or  rename  its  products  in  order  to  avoid  encroaching  on  the  intellectual  property  rights  of  third  parties.  This  could  prove  to  be
impossible or costly in terms of time and financial resources and could be detrimental to Innate's marketing efforts. Should any of these risks
materialize, this could have a material adverse effect on Innate's business, prospects, financial condition and results of operations.

61

Intellectual property rights do not necessarily address all potential threats.

The  degree  of  future  protection  afforded  by  the  Company's  intellectual  property  rights  is  uncertain  because  intellectual  property  rights  have
limitations and may not adequately protect its business or permit it to maintain its competitive advantage. For example:

•

•

•

•

•

•

•

•

•

•

others may be able to make products that are the same as or similar to its product candidates or utilize similar technology but that are
not covered by the claims of the patents that the Company licenses or may own in the future;

the Company, or its license partners or current or future collaborators, might not have been the first to make the inventions covered by
the issued patent or pending patent application that the Company licenses or may own in the future;

the  Company,  or  its  license  partners  or  current  or  future  collaborators,  might  not  have  been  the  first  to  file  patent  applications
covering certain of its or their inventions;

others  may  independently  develop  similar  or  alternative  technologies  or  duplicate  any  of  the  Company's  technologies  without
infringing its owned or licensed intellectual property rights;

it is possible that the Company's owned or licensed pending patent applications will not lead to issued patents;

issued patents that the Company holds rights to may be held invalid or unenforceable, including as a result of legal challenges by its
competitors;

its competitors might conduct research and development activities in countries where the Company does not have patent rights and
then use the information learned from such activities to develop competitive products for sale in its major commercial markets;

the Company may not develop additional proprietary technologies that are patentable;

the patents of others may harm the Company's business; and

the  Company  may  choose  not  to  file  a  patent  in  order  to  maintain  certain  trade  secrets  or  know-how,  and  a  third  party  may
subsequently file a patent covering such intellectual property.

Should any of these events occur, they could have a material adverse effect on Innate's business, financial condition, results of operations and
prospects.

Risks Related to Ownership of the Company's Ordinary Shares and the ADSs

The trading price of Innate's equity securities may be volatile, and purchasers of its ordinary shares or ADSs could incur substantial losses.

It is likely that the price of the Company's ordinary shares and ADSs will be significantly affected by events such as announcements regarding
scientific and clinical results concerning product candidates currently being developed by us, its collaboration partners or its main competitors,
changes in market conditions related to its sector of activity, announcements of new contracts, technological innovations and collaborations by
Innate  or  its  main  competitors,  developments  concerning  intellectual  property  rights,  as  well  as  the  development,  regulatory  approval  and
commercialization of new products by Innate or its main competitors and changes in its financial results.

Equity markets are subject to considerable price fluctuations, and often these movements do not reflect the operational and financial performance
of the listed companies concerned. In particular, biotechnology

62

companies’  share  prices  have  been  highly  volatile  and  may  continue  to  be  highly  volatile  in  the  future. As  the  Company  operates  in  a  single
industry, Innate is especially vulnerable to these factors to the extent that they affect its industry. Fluctuations in the stock market as well as the
macro-economic environment could significantly affect the price of its ordinary shares. As a result of this volatility, investors may not be able to
sell their ordinary shares or ADSs at or above the price originally paid for the security. The market price for Innate Pharma's ordinary shares and
ADSs may be influenced by many factors, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

actual or anticipated fluctuations in its financial condition and operating results;

actual or anticipated changes in its growth rate relative to its competitors;

competition from existing products or new products that may emerge;

announcements by Innate or its competitors of significant acquisitions, strategic partnerships, joint ventures, collaborations or capital
commitments;

adverse results of delays in Innate's or any of its competitors’ preclinical studies or clinical trials;

adverse regulatory decisions, including failure to receive regulatory approval for any of its product candidates;

the termination of a strategic alliance or the inability to establish additional strategic alliances;

failure  to  meet  or  exceed  financial  estimates  and  projections  of  the  investment  community  or  that  the  Company  provides  to  the
public;

issuance of new or updated research or reports by securities analysts;

fluctuations in the valuation of companies perceived by investors to be comparable to us;

ordinary share and ADS price and volume fluctuations attributable to inconsistent trading volume levels of its ordinary shares and
ADSs;

price and volume fluctuations in trading of its ordinary shares on Euronext Paris;

additions or departures of key management or scientific personnel;

disputes or other developments related to proprietary rights, including patents, litigation matters and its ability to obtain patent and
other intellectual property protection for its technologies;

changes  to  coverage  policies  or  reimbursement  levels  by  commercial  third-party  payors  and  government  payors  and  any
announcements relating to coverage policies or reimbursement levels;

announcement or expectation of additional debt or equity financing efforts;

sales of its ordinary shares or ADSs by Innate, its insiders or its other shareholders; and

general economic and market conditions.

These  and  other  market  and  industry  factors  may  cause  the  market  price  and  demand  for  Innate's  ordinary  shares  and  ADSs  to  fluctuate
substantially, regardless of its actual operating performance, which may limit or prevent investors from readily selling their ordinary shares or
ADSs and may otherwise negatively affect the liquidity of the trading market for the ordinary shares and ADSs.

63

If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about Innate's business, the price of
the ordinary shares or ADSs and their trading volume could decline.

The trading market for the ADSs and ordinary shares depends in part on the research and reports that securities or industry analysts publish about
Innate or its business. As a public company in France since 2006, the Company's equity securities are currently subject to coverage by a number
of analysts. If fewer securities or industry analysts cover its company, the trading price for the ADSs and ordinary shares would be negatively
impacted. If one or more of the analysts who covers Innate downgrades Innate's equity securities or publishes incorrect or unfavorable research
about Innate's business, the price of the ordinary shares and ADSs would likely decline. If one or more of these analysts ceases coverage of the
Company  or  fails  to  publish  reports  on  Innate  regularly,  or  downgrades  Innate's  securities,  demand  for  the  ordinary  shares  and ADSs  could
decrease, which could cause the price of the ordinary shares and ADSs or their trading volume to decline.

The  Company  does  not  currently  intend  to  pay  dividends  on  its  securities  and,  consequently,  your  ability  to  achieve  a  return  on  your
investment  will  depend  on  appreciation  in  the  price  of  the  ordinary  shares  and ADSs.  In  addition,  French  law  may  limit  the  amount  of
dividends the Company is able to distribute.

Innate has never declared or paid any cash dividends on its ordinary shares and does not currently intend to do so for the foreseeable future. The
Company currently intends to invest its future earnings, if any, to fund its growth. Therefore, the holders of Innate's ordinary shares and ADSs
are not likely to receive any dividends for the foreseeable future, and the success of an investment in its ordinary shares and ADSs depends upon
any future appreciation in value. Consequently, investors may need to sell all or part of their holdings of the ordinary shares or ADSs after price
appreciation, which may never occur, as the only way to realize any future gains on their investment. There is no guarantee that the ordinary
shares or ADSs will appreciate in value or even maintain the price at which Innate's shareholders have purchased them.

Further, under French law, the determination of whether the Company has been sufficiently profitable to pay dividends is made on the basis of its
statutory  financial  statements  prepared  and  presented  in  accordance  with  accounting  standards  applicable  in  France.  Moreover,  pursuant  to
French law, the Company must allocate 5% of its unconsolidated net profit for each year to its legal reserve fund before dividends, should the
Company propose to declare any, may be paid for that year, until the amount in the legal reserve is equal to 10% of the aggregate nominal value
of its issued and outstanding share capital. In addition, payment of dividends may subject Innate to additional taxes under French law. Therefore,
Innate may be more restricted in its ability to declare dividends than companies that are not incorporated in France.

In addition, exchange rate fluctuations may affect the amount of euros that the Company is able to distribute, and the amount in U.S. dollars that
its shareholders receive upon the payment of cash dividends or other distributions the Company declares and pays in euro, if any. These factors
could harm the value of the ADSs, and, in turn, the U.S. dollar proceeds that holders receive from the sale of the ADSs.

Future sales, or the possibility of future sales, of a substantial number of Innate's ADSs or ordinary shares could adversely affect the market
price of its ADSs and ordinary shares.

Future sales of a substantial number of Innate's ADSs or ordinary shares, or the perception that such sales will occur, could cause a decline in the
market price of its ADSs and/or ordinary shares. Sales in the United States of Innate ADSs and ordinary shares held by its directors, officers and
affiliated shareholders or ADS holders are subject to restrictions. If these shareholders or ADS holders sell substantial amounts of ordinary shares
or ADSs in the public market, or the market perceives that such sales may occur, the

64

market  price  of  Innate's ADSs  or  ordinary  shares  and  its  ability  to  raise  capital  through  an  issue  of  equity  securities  in  the  future  could  be
adversely affected.

The dual listing of Innate's ordinary shares and the ADSs may adversely affect the liquidity and value of the ADSs.

Innate's ADSs are listed on the Nasdaq, and its ordinary shares are admitted to trading on Euronext Paris. Trading of the ADSs or ordinary shares
in these markets take place in different currencies (U.S. dollars on the Nasdaq and euro on Euronext Paris), and at different times (resulting from
different time zones, different trading days and different public holidays in the United States and France). The trading prices of the Company's
ordinary shares on these two markets may differ due to these and other factors. Any decrease in the price of Innate's ordinary shares on Euronext
Paris  could  cause  a  decrease  in  the  trading  price  of  the ADSs  on  Nasdaq.  Investors  could  seek  to  sell  or  buy  Innate's  ordinary  shares  to  take
advantage of any price differences between the markets through a practice referred to as arbitrage. Any arbitrage activity could create unexpected
volatility in both its share prices on one exchange, and the ordinary shares available for trading on the other exchange. In addition, holders of
ADSs are not immediately able to surrender their ADSs and withdraw the underlying ordinary shares for trading on the other market without
effecting  necessary  procedures  with  the  depositary.  This  could  result  in  time  delays  and  additional  cost  for  holders  of ADSs.  The  Company
cannot predict the effect of this dual listing on the value of its ordinary shares and the ADSs. However, the dual listing of its ordinary shares and
the ADSs  may  reduce  the  liquidity  of  these  securities  in  one  or  both  markets  and  may  adversely  affect  the  development  of  an  active  trading
market for the ADSs in the United States.

The rights of shareholders in companies subject to French corporate law differ in material respects from the rights of shareholders of
corporations incorporated in the United States.

The Company is a French company with limited liability. Its corporate affairs are governed by its bylaws and by the laws governing companies
incorporated in France. The rights of shareholders and the responsibilities of members of Innate's Executive Board and of its Supervisory Board
are in many ways different from the rights and obligations of shareholders in companies governed by the laws of U.S. jurisdictions. For example,
in  the  performance  of  its  duties,  Innate's  Executive  Board  is  required  by  French  law  to  consider  the  interests  of  Innate,  its  shareholders,  its
employees and other stakeholders, rather than solely Innate's shareholders and/or creditors. It is possible that some of these parties have interests
that are different from, or in addition to, your interests as a shareholder or holder of ADSs. See “Item 16G.—Corporate Governance.”

U.S. investors may have difficulty enforcing civil liabilities against the Company and members of the Executive Board and the Supervisory
Board.

Most of the members of Innate's Executive Board and Supervisory Board and the experts named therein are non-residents of the United States,
and all or a substantial portion of its assets and the assets of such persons are located outside the United States. As a result, it may not be possible
to serve process on such persons or Innate in the United States or to enforce judgments obtained in U.S. courts against them or Innate based on
civil liability provisions of the securities laws of the United States. Additionally, it may be difficult to obtain jurisdiction over us or our non-U.S.
resident members of the Executive Board and Supervisory Board in U.S. courts in actions predicated on the civil liability provisions of the U.S.
federal securities law, or assert U.S. securities law claims in actions originally instituted outside of the United States. Foreign courts may refuse
to hear a U.S. securities law claim because foreign courts may not be the most appropriate forums in which to bring such a claim. Even if a
foreign court agrees to hear a claim, it may determine that the law of the jurisdiction in which the foreign court resides, and not U.S. law, is
applicable to the claim. Further, if U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact, which can be a
time-consuming and costly process, and certain matters of

65

procedure  would  still  be  governed  by  the  law  of  the  jurisdiction  in  which  the  foreign  court  resides.  In  particular,  there  is  some  doubt  as  to
whether French courts would recognize and enforce certain civil liabilities against us or our Supervisory Board or our Executive Board under
U.S. securities laws in original actions or judgments of U.S. courts based upon the civil liability provisions of the U.S. federal securities laws.

In  addition,  awards  of  punitive  damages  in  actions  brought  in  the  United  States  or  elsewhere  may  be  unenforceable  in  France. An  award  for
monetary damages under the U.S. securities laws would be considered punitive if the amount awarded is disproportionate to the harm suffered
and the defendant’s breach. French law provides that a shareholder, or a group of shareholders, may initiate a legal action to seek indemnification
from the directors of a corporation in the corporation’s interest if it fails to bring such legal action itself. If so, any damages awarded by the court
are paid to the corporation, and any legal fees relating to such action may be borne by the relevant shareholder or the group of shareholders. The
enforceability of any judgment in France will depend on the particular facts of the case as well as the laws and treaties in effect at the time. A
final  judgment  for  the  payment  of  money  rendered  by  any  federal  or  state  court  in  the  United  States  based  on  civil  liability,  whether  or  not
predicated solely upon the U.S. federal securities laws, would only be recognized and enforced in France provided that a French judge considers
that this judgment meets the French legal requirements concerning the recognition and the enforcement of foreign judgments and is capable of
being  immediately  enforced  in  the  United  States.  The  United  States  and  France  do  not  currently  have  a  treaty  providing  for  recognition  and
enforcement of judgments, other than arbitration awards, in civil and commercial matters.

Innate's bylaws and French corporate law contain provisions that may delay or discourage a takeover attempt.

Provisions contained in the Company's bylaws and French corporate law could make it more difficult for a third party to acquire the Company,
even if doing so might be beneficial to its shareholders. In addition, provisions of its bylaws impose various procedural and other requirements,
which could make it more difficult for shareholders to effect certain corporate actions. These provisions include the following:

•

•

•

•

under  French  law,  the  owner  of  90%  of  the  share  capital  or  voting  rights  of  a  public  company  listed  on  a  regulated  market  in  a
Member State of the European Union or in a state party to the EEA Agreement, including from the main French stock exchange, has
the right to force out minority shareholders following a tender offer made to all shareholders;

under French law, a non-resident of France, as well as any French entity controlled by non-residents of France, may have to file a
declaration for statistical purposes with the Bank of France (Banque de France) within 20 working days following the date of certain
direct foreign investments in us, including any purchase of the Company's ADSs. In particular, such filings are required in connection
with investments exceeding €15,000,000 that lead to the acquisition of at least 10% of the Company's share capital or voting rights or
cross such 10% threshold;

under  French  law,  certain  investments  in  a  French  company  relating  to  certain  strategic  industries  by  individuals  or  entities  not
residents in a Member State of the EU are subject to prior authorization of the Ministry of Economy;

a  merger  (i.e.,  in  a  French  law  context,  a  share  for  share  exchange  following  which  the  Company  would  be  dissolved  into  the
acquiring  entity  and  its  shareholders  would  become  shareholders  of  the  acquiring  entity)  of  the  Company  into  a  company
incorporated in the European Union would require the approval of the Company's Executive Board, as well as a two-thirds majority
of the votes held by the shareholders present, represented by proxy or voting by mail at the relevant meeting;

•

•

•

•

a  merger  of  the  Company  into  a  company  incorporated  outside  of  the  European  Union  would  require  100%  of  its  shareholders  to
approve it;

under French law, a cash merger is treated as a share purchase and would require the consent of each participating shareholder;

Innate's shareholders may in the future grant the Company's Executive Board broad authorizations to increase Innate's share capital or
to  issue  additional  ordinary  shares  or  other  securities  (for  example,  warrants)  to  Innate's  shareholders,  the  public  or  qualified
investors, including as a possible defense following the launching of a tender offer for Innate's ordinary shares;

its shareholders have preferential subscription rights on a pro rata basis on the issuance by Innate of any additional securities for cash
or a set-off of cash debts, which rights may only be waived by the extraordinary general meeting (by a two-thirds majority vote) of
the Company's shareholders or on an individual basis by each shareholder;

Innate's Supervisory Board appoints the members of the Executive Board and shall fill any vacancy within two months;

Innate's Supervisory Board has the right to appoint members of the Supervisory Board to fill a vacancy created by the resignation or
death of a member of the Supervisory Board for the remaining duration of such member’s term of office, and subject to the approval
by the shareholders of such appointment at the next shareholders’ meeting, which prevents shareholders from having the sole right to
fill vacancies on the Company's Supervisory Board;

its Executive Board can be convened by the chairman of the Executive Board or other members of the Executive Board delegated for
this purpose;

its Supervisory Board can be convened by the chairman or the vice-chairman of the Supervisory Board. A member of the Executive
Board or one-third of the members of the Supervisory Board may send a written request to the chairman to convene the Supervisory
Board.  If  the  chairman  does  not  convene  the  Supervisory  Board  15  days  following  the  receipt  of  such  request,  the  authors  of  the
request may themselves convene the Supervisory Board;

its  Supervisory  Board  meetings  can  only  be  regularly  held  if  at  least  half  of  its  members  attend  either  physically  or  by  way  of
videoconference or teleconference enabling the members’ identification and ensuring their effective participation in the Supervisory
Board’s decisions;

approval of at least a majority of the votes held by shareholders present, represented by a proxy, or voting by mail at the relevant
ordinary shareholders’ general meeting is required to remove members of the Executive Board and/or members of the Supervisory
Board with or without cause;

the crossing of certain ownership thresholds has to be disclosed and can impose certain obligations;

advance  notice  is  required  for  nominations  to  the  Supervisory  Board  or  for  proposing  matters  to  be  acted  upon  at  a  shareholders’
meeting, except that a vote to remove and replace a member of the Supervisory Board can be proposed at any shareholders’ meeting
without notice;

transfers  of  shares  shall  comply  with  applicable  insider  trading  rules  and  regulations,  and  in  particular  with  the  Market  Abuse
Regulation 596/2014 of April 16, 2014, as amended; and

67

•

pursuant  to  French  law,  the  Company's  bylaws,  including  the  sections  relating  to  the  number  of  members  of  the  Executive  and
Supervisory  Boards,  and  election  and  removal  of  members  of  the  Executive  and  Supervisory  Boards  from  office  may  only  be
modified by a resolution adopted by two-thirds of the votes of the Company's shareholders present, represented by a proxy or voting
by mail at the meeting.

Purchasers of ADSs in the U.S. offering are not directly holding the Company's ordinary shares.

A holder of ADSs is not treated as one of Innate Pharma's shareholders and does not have direct shareholder rights. French law governs Innate's
shareholder rights. The depositary, through the custodian or the custodian’s nominee, is the holder of the ordinary shares underlying ADSs held
by purchasers of ADSs in the U.S. offering. Purchasers of ADSs in the U.S. offering have ADS holder rights. The deposit agreement among us,
the depositary and purchasers of ADSs in the U.S. offering, as an ADS holder, and all other persons directly and indirectly holding ADSs, sets
out ADS holder rights, as well as the rights and obligations of Innate and the depositary.

Your right as a holder of ADSs to participate in any future preferential subscription rights offering or to elect to receive dividends in shares
may be limited, which may cause dilution to your holdings.

According to French law, if the Company issues additional securities for cash, current shareholders will have preferential subscription rights for
these securities on a pro rata basis unless they waive those rights at an extraordinary meeting of its shareholders (by a two-thirds majority vote)
or individually by each shareholder. However, Innate's ADS holders in the United States will not be entitled to exercise or sell such rights unless
the  Company  registers  the  rights  and  the  securities  to  which  the  rights  relate  under  the  Securities Act  or  an  exemption  from  the  registration
requirements  is  available.  In  addition,  the  deposit  agreement  provides  that  the  depositary  will  not  make  rights  available  to  you  unless  the
distribution to ADS holders of both the rights and any related securities are either registered under the Securities Act or exempt from registration
under the Securities Act. Further, if the Company offers holders of its ordinary shares the option to receive dividends in either cash or shares,
under the deposit agreement the depositary may require satisfactory assurances from Innate that extending the offer to holders of ADSs does not
require registration of any securities under the Securities Act before making the option available to holders of ADSs. The Company is under no
obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be
declared effective. Moreover, the Company may not be able to establish an exemption from registration under the Securities Act. Accordingly,
ADS  holders  may  be  unable  to  participate  in  the  Company's  rights  offerings  or  to  elect  to  receive  dividends  in  shares  and  may  experience
dilution in their holdings. In addition, if the depositary is unable to sell rights that are not exercised or not distributed or if the sale is not lawful
or reasonably practicable, it will allow the rights to lapse, in which case you will receive no value for these rights.

You may not be able to exercise your right to vote the ordinary shares underlying your ADSs.

Holders of ADSs may exercise voting rights with respect to the ordinary shares represented by the ADSs only in accordance with the provisions
of the deposit agreement. The deposit agreement provides that, upon receipt of notice of any meeting of holders of Innate's ordinary shares, the
depositary will fix a record date for the determination of ADS holders who shall be entitled to give instructions for the exercise of voting rights.
Upon  timely  receipt  of  notice  from  us,  if  the  Company  so  requests,  the  depositary  shall  distribute  to  the  holders  as  of  the  record  date  (i)  the
notice of the meeting or solicitation of consent or proxy sent by Innate and (ii) a statement as to the manner in which instructions may be given
by the holders.

You may instruct the depositary of your ADSs to vote the ordinary shares underlying your ADSs. Otherwise, you will not be able to exercise
your right to vote, unless you withdraw the ordinary shares underlying the ADSs you hold. However, you may not know about the meeting far
enough in advance to

68

withdraw those ordinary shares. If the Company asks for your instructions, the depositary, upon timely notice from us, will notify you of the
upcoming vote and arrange to deliver its voting materials to you. The Company cannot guarantee you that you will receive the voting materials
in time to ensure that you can instruct the depositary to vote your ordinary shares or to withdraw your ordinary shares so that you can vote them
yourself. If the depositary does not receive timely voting instructions from you, it may give a proxy to a person designated by Innate to vote the
ordinary shares underlying your ADSs. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or
for the manner of carrying out voting instructions. This means that you may not be able to exercise your right to vote, and there may be nothing
you can do if the ordinary shares underlying your ADSs are not voted as you requested.

You may be subject to limitations on the transfer of your ADSs and the withdrawal of the underlying ordinary shares.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it
deems  expedient  in  connection  with  the  performance  of  its  duties. The  depositary  may  refuse  to  deliver,  transfer  or  register  transfers  of  your
ADSs generally when the Company's books or the books of the depositary are closed, or at any time if the Company or the depositary thinks it is
advisable to do so because of any requirement of law, government or governmental body, or under any provision of the deposit agreement, or for
any other reason subject to your right to cancel your ADSs and withdraw the underlying ordinary shares. Temporary delays in the cancellation of
your ADSs and withdrawal of the underlying ordinary shares may arise because the depositary has closed its transfer books or the Company has
closed  its  transfer  books,  the  transfer  of  ordinary  shares  is  blocked  to  permit  voting  at  a  shareholders’  meeting  or  the  Company  is  paying  a
dividend on its ordinary shares. In addition, you may not be able to cancel your ADSs and withdraw the underlying ordinary shares when you
owe  money  for  fees,  taxes  and  similar  charges  and  when  it  is  necessary  to  prohibit  withdrawals  in  order  to  comply  with  any  laws  or
governmental regulations that apply to ADSs or to the withdrawal of ordinary shares or other deposited securities.

As  a  foreign  private  issuer,  the  Company  is  exempt  from  a  number  of  rules  under  the  U.S.  securities  laws  and  is  permitted  to  file  less
information with the SEC than a U.S. company.

Innate  is  a  foreign  private  issuer,  as  defined  in  the  SEC’s  rules  and  regulations  and,  consequently,  it  is  not  subject  to  all  of  the  disclosure
requirements applicable to public companies organized within the United States. For example, the Company is exempt from certain rules under
the  Exchange  Act  that  regulate  disclosure  obligations  and  procedural  requirements  related  to  the  solicitation  of  proxies,  consents  or
authorizations applicable to a security registered under the Exchange Act, including the U.S. proxy rules under Section 14 of the Exchange Act.
In addition, the Company's Executive Board and Supervisory Board members are exempt from the reporting and “short-swing” profit recovery
provisions of Section 16 of the Exchange Act and related rules with respect to their purchases and sales of Innate's securities. Moreover, while
the Company currently makes annual and semi-annual filings with respect to its listing on Euronext Paris and files financial reports on an annual
and semi-annual basis, it is not required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. public
companies  and  is  not  required  to  file  quarterly  reports  on  Form  10-Q  or  current  reports  on  Form  8-K  under  the  Exchange Act.  In  addition,
foreign private issuers are not required to file their annual report on Form 20-F until four months after the end of each fiscal year. Accordingly,
there is and will be less publicly available information concerning the Company than there would be if the Company were not a foreign private
issuer.

As a foreign private issuer, the Company is permitted to adopt certain home country practices in relation to corporate governance matters
that differ significantly from Nasdaq corporate governance

69

listing standards, and these practices may afford less protection to shareholders than they would enjoy if Innate complied fully with Nasdaq
corporate governance listing standards.

As a foreign private issuer listed on Nasdaq, the Company is subject to Nasdaq's corporate governance listing standards. However, Nasdaq rules
permit foreign private issuers to follow the corporate governance practices of their home country. Therefore, as a general matter, the Company
refers to the French Middlenext corporate governance code for corporate governance matters, and thus its corporate governance practices may
differ  significantly  from  Nasdaq  corporate  governance  listing  standards.  For  example,  while  the  Nasdaq  corporate  governance  rules  would
require a majority of the Supervisory Board to be independent, the Middlenext corporate governance code requires that at least one third of the
members of Supervisory Board be independent and encourages 50% independent directors. Currently, all of the members of Innate’s Supervisory
Board are independent (as defined by the Middlenext code) and meet both the Middlenext and Nasdaq requirements for independence. However,
in  the  future,  the  composition  of  the  Board  may  change  such  that  the  Company  only  meets  the  Middlenext  requirement,  but  not  the  Nasdaq
requirements  for  independence.  Currently,  the  Company  intends  to  follow  home  country  practice  to  the  maximum  extent  possible. Therefore,
Innate  Pharma's  shareholders  may  be  afforded  less  protection  than  they  otherwise  would  have  under  corporate  governance  listing  standards
applicable to U.S. domestic issuers. For an overview of Innate's corporate governance practices, see “Item 16G.—Corporate Governance.”

The Company incurs significant costs as a result of being a public company.

As a public company, Innate has incurred and will continue to incur significant legal, accounting and other expenses, including costs associated
with  public  company  reporting  requirements.  The  Company  has  also  incurred  and  will  continue  to  incur  costs  associated  with  corporate
governance  requirements,  including  requirements  of  the  Sarbanes-Oxley Act,  as  well  as  rules  implemented  by  the  SEC  and  Nasdaq  Capital
Market,  which  include  requirements  with  respect  to  corporate  governance  practices  of  public  companies.  The  Company  ceased  to  be  an
“emerging  growth  company”  on  December  31,  2024,  and  is  therefore  no  longer  eligible  for  reduced  disclosure  requirements  and  exemptions
applicable to emerging growth companies. As the Company is no longer an emerging growth company, it will be required to devote significant
additional attention from management toward ensuring compliance with the requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002
and  will  likely  incur  significant  additional  costs,  which  could  include  higher  legal  fees,  accounting  fees  and  fees  associated  with  investor
relations activities, among others. The stringent standards set by the Sarbanes-Oxley Act require that the Company's audit committee be advised
and regularly updated on management’s review of internal control over financial reporting. To comply with this obligation, the Company must
maintain  an  extensive  framework  of  internal  control  over  financial  reporting,  that  needs  to  be  regularly  updated  and  tested.  The  Company's
independent  registered  public  accounting  firm  is  required  to  attest  to  the  effectiveness  of  its  internal  controls  over  financial  reporting.  The
management  of  the  Company  may  not  be  able  to  effectively  and  timely  implement  controls  and  procedures  that  adequately  respond  to  the
increased regulatory compliance and reporting requirements that are now applicable to the Company as a public company listed in the United
States. If the Company does not succeed in maintaining the appropriate level of internal control, it could result in material misstatements in its
financial statements, result in the loss of investor confidence in the reliability of its financial statements and subject it to regulatory scrutiny and
sanctions, which in turn could harm the market value of its ordinary shares and ADSs.

The Company may lose its foreign private issuer status in the future, which could result in significant additional cost and expense.

While Innate currently qualifies as a foreign private issuer, the determination of foreign private issuer status is made annually on the last business
day of an issuer’s most recently completed second fiscal quarter and, accordingly, the Company's next determination will be made on June 30,
2025. In the future,

70

the Company would lose its foreign private issuer status if the Company fails to meet the requirements necessary to maintain its foreign private
issuer status as of the relevant determination date. For example, if more than 50% of its securities are held by U.S. residents and more than 50%
of the members of its Executive Board or Supervisory Board are residents or citizens of the United States, Innate could lose its foreign private
issuer status.

The regulatory and compliance costs to Innate under U.S. securities laws as a U.S. domestic issuer may be significantly more than costs Innate
incurs as a foreign private issuer. If the Company is not a foreign private issuer, Innate will be required to file periodic reports and registration
statements on U.S. domestic issuer forms with the SEC, which are more detailed and extensive in certain respects than the forms available to a
foreign  private  issuer.  The  Company  would  be  required  under  current  SEC  rules  to  prepare  its  financial  statements  in  accordance  with  U.S.
generally  accepted  accounting  principles,  or  U.S.  GAAP,  rather  than  IFRS,  and  to  modify  certain  of  its  policies  to  comply  with  corporate
governance practices required of U.S. domestic issuers. Such conversion of Innate's financial statements to U.S. GAAP would involve significant
time and cost. In addition, the Company may lose its ability to rely upon exemptions from certain corporate governance requirements on U.S.
stock  exchanges  that  are  available  to  foreign  private  issuers  such  as  the  ones  described  above  and  exemptions  from  procedural  requirements
related to the solicitation of proxies.

If the Company is a passive foreign investment company, there could be adverse U.S. federal income tax consequences to U.S. holders.

Based on Innate's analysis of its income, assets, activities and market capitalization for its taxable year ended December 31, 2024, and although
the matter is not free from doubt, the Company believes that it was not a passive foreign investment company (PFIC) for the taxable year ended
December 31, 2024. However, there can be no assurance that Innate will not be a PFIC in the current year or for any future taxable year. Under
the Code, a non-U.S. company will be a PFIC for any taxable year in which (1) 75% or more of its gross income consists of passive income or
(2) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income. For
purposes of these tests, passive income includes dividends, interest, gains from the sale or exchange of investment property and certain rents and
royalties  and  passive  assets  generally  includes  cash  and  cash  equivalents.  In  addition,  for  purposes  of  the  above  calculations,  a  non-U.S.
corporation that directly or indirectly owns at least 25% by value of the shares of another corporation is treated as if it held its proportionate
share of the assets and received directly its proportionate share of the income of such other corporation. The status of the Company as a PFIC
depends  on  the  composition  of  its  income  (including  whether  reimbursements  of  certain  refundable  research  tax  credits  will  constitute  gross
income for purposes of the PFIC income test) and the composition and value of its assets. The value of the Company’s assets may be determined
in large part by reference to the market value of the ordinary shares or ADSs, which may fluctuate substantially. The Company’s status as a PFIC
may  also  depend  in  part  on  the  amount  of  the  amount  of  cash  on  the  Company’s  balance  sheet,  the  cash  proceeds  from  any  fund-raising
activities, and how quickly the Company utilizes such cash in its business.

If  Innate  is  a  PFIC  for  any  taxable  year  during  which  a  U.S.  holder  (as  defined  below  under  “Item  10E.—Taxation  –  Material  U.S.  Federal
Income  Tax”)  holds  its  ordinary  shares  or ADSs,  the  Company  will  continue  to  be  treated  as  a  PFIC  with  respect  to  such  U.S.  holder  in  all
succeeding  years  during  which  the  U.S.  holder  owns  the  ordinary  shares  or ADSs,  regardless  of  whether  the  Company  continues  to  meet  the
PFIC test described above, unless the U.S. holder makes a specified election once Innate ceases to be a PFIC. If the Company is a PFIC for any
taxable  year  during  which  a  U.S.  holder  holds  its  ordinary  shares  or  ADSs,  the  U.S.  holder  may  be  subject  to  adverse  tax  consequences
regardless  of  whether  Innate  Pharma  continues  to  qualify  as  a  PFIC,  including  ineligibility  for  any  preferred  tax  rates  on  capital  gains  or  on
actual or deemed dividends, interest charges on certain taxes treated as deferred, and additional

71

reporting  requirements.  For  further  discussion  of  the  PFIC  rules  and  the  adverse  U.S.  income  tax  consequences  in  the  event  the  Company  is
classified as a PFIC, see the section of this Annual Report titled “Item 10E.—Taxation– Material U.S. Federal Income Tax Considerations.”

If a United States person is treated as owning at least 10% of Innate's ordinary shares, such holder may be subject to adverse U.S. federal
income tax consequences.

If a U.S. holder is treated as owning, directly, indirectly or constructively, at least 10% of the value or voting power of Innate's ordinary shares or
ADSs, such U.S. holder may be treated as a “United States shareholder” with respect to each “controlled foreign corporation” in its group, if any.
Innate  Pharma  group  currently  includes  one  U.S.  subsidiary  and,  therefore,  under  current  law  its  current  non-U.S.  subsidiary  and  any  future
newly formed or acquired non-U.S. subsidiaries will be treated as controlled foreign corporations, regardless of whether the Company is treated
as  a  controlled  foreign  corporation. A  United  States  shareholder  of  a  controlled  foreign  corporation  may  be  required  to  annually  report  and
include  in  its  U.S.  taxable  income  its  pro  rata  share  of  “Subpart  F  income,”  “global  intangible  low-taxed  income”  and  investments  in  U.S.
property by controlled foreign corporations, regardless of whether Innate makes any distributions. An individual that is a U.S. shareholder with
respect to a controlled foreign corporation generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a
U.S.  shareholder  that  is  a  U.S.  corporation.  Failure  to  comply  with  controlled  foreign  corporation  reporting  obligations  may  subject  a  U.S.
shareholder  to  significant  monetary  penalties.  The  Company  cannot  provide  any  assurances  that  it  will  furnish  to  any  U.S.  shareholder
information that may be necessary to comply with the reporting and tax paying obligations applicable under the controlled foreign corporation
rules of the Code. U.S. holders should consult their tax advisors regarding the potential application of these rules to their investment in Innate's
ordinary shares or ADSs.

B.    Business Overview

Innate Pharma S.A. is a global, clinical-stage biotechnology company developing immunotherapies for cancer patients. Its innovative approach
aims  to  harness  the  innate  immune  system  through  therapeutic  antibodies  and  its ANKET   (Antibody-based  NK  cell  Engager  Therapeutics)
proprietary  platform.  Innate’s  portfolio  includes  our  lead  proprietary  program  lacutamab,  developed  for  advanced  form  of  cutaneous  T  cell
lymphomas and peripheral T cell lymphomas indications; monalizumab developed with AstraZeneca for non-small cell lung cancer (NSCLC)
indications, as well as ANKET  multi-specific NK cell engagers to address multiple tumor types. The Company has developed, internally and
through its business development strategy, a broad and diversified portfolio including eight clinical product candidates and a robust preclinical
pipeline. Innate has entered into collaborations with leaders in the biopharmaceutical industry, such as AstraZeneca and Sanofi. Innate Pharma
believes  its  product  candidates  and  clinical  development  approach  are  differentiated  from  current  immuno-oncology  therapies  and  have  the
potential to significantly improve the clinical outcome for patients with cancer.

The immune system is the body’s natural defense against invading organisms and pathogens and is comprised of two arms: the innate immune
system  and  the  adaptive  immune  system.  Recent  immunotherapy  developments  have  focused  on  generating  a  tumor  antigen-specific  T  cell
response and have led to an unprecedented change in the treatment paradigm of many solid tumor cancers. Despite these successes, the breadth
and durability of the clinical benefit achieved has been limited to a subset of patients and tumor types because of limited effect against solid
tumors and toxicity. The Company's innovative approach to immuno-oncology aims to broaden and amplify anti-tumoral immune responses by
leveraging both the adaptive and the innate immune systems.

The  innate  immune  system  is  comprised  of  a  variety  of  cells,  including  Natural  Killer  (NK)  cells,  which  are  involved  in  anti-cancer
immunosurveillance through a variety of modalities. Activation of the innate immune system also helps trigger the adaptive immune system to
elicit a response directed against specific antigens and can provide durable immune memory. Innate's scientific expertise, strategic collaborations
and discovery engine to seek to harness the potential of the innate immune system.

73

The Company is developing a pipeline of innovative immunotherapies that it believes have the potential to provide significant clinical benefits to
cancer patients. The following table summarizes Innate's current pipeline.

In addition to these assets, the Company has an active development pipeline with programs in the discovery and preclinical stages.

Innate  Pharma's  collaborations  with  leaders  in  the  biopharmaceutical  industry,  such  as AstraZeneca  and  Sanofi,  allow  Innate  to  leverage  the
expertise and resources of large pharmaceutical companies and research institutions with the goal of accelerating the development, registration
and  launch  of  several  of  Innate  Pharma's  assets  while  providing  the  Company  with  financing  to  expand  the  development  of  its  proprietary
product candidates. Since 2015, the Company has received an aggregate of $696.1 million (€619.7 million) in upfront and milestone payments
and equity investments from its collaborations. This amount includes a total of €62.6 million received from AstraZeneca following its investment
in the Company's capital in October 2018. Under Innate's existing collaboration and license agreements that become effective upon the exercise
by its collaborators of options to license future product candidates, the Company may be eligible to receive an aggregate of approximately up to
$2.8  billion  in  future  contingent  payments.  With  respect  to  the  programs  for  which  Innate  Pharma  has  an  existing  collaboration  or  similar
agreement, future contingent payments are dependent upon Innate's achievement of specified development, regulatory and commercial related
milestones. With respect to the programs for which Innate Pharma's collaborators have been granted an option, future contingent payments are
dependent upon Innate's collaborators exercising such options, which would result in up-front option exercise fees, and upon its achievement of
specific development and sales milestones in those particular programs. The aggregate $2.8billion in future contingent payments assumes that its
collaborators exercise all of the options the Company has granted to them and that Innate achieves all related development, clinical, regulatory
and sales milestones.

The Company's Strategy

Innate's goal is to harness the immune system for the treatment of oncological conditions with serious unmet medical need. By leveraging its
extensive experience in immuno-oncology research and

74

development,  the  Company  strives  to  continue  to  discover  and  develop  a  broad  and  diversified  portfolio  of  first-  and  best-in-class
immunotherapies across various therapeutic modalities.

In January 2025, Innate announced its updated strategy for company growth, anchored on early clinical development of proprietary assets with
single-agent potential.

The key elements of its strategy include:

• Drive innovation with first-in-class ANKET® Platform: A new era in NK cell therapeutics is at the heart of Innate Pharma’s strategy,

based around its validated, proprietary Antibody-based NK Cell Engager Therapeutics (ANKET®) platform. This cutting-edge
technology with anticipated applications in hematologic malignancies, solid tumors, and autoimmune diseases leverages the advantages
of harnessing NK cell effector functions and can create proliferation of NK cells. By advancing its clinical pipeline, Innate aims to
exploit therapeutic possibilities in oncology and autoimmune diseases. IPH6501, Innate’s proprietary ANKET® is currently being
investigated in a Phase 1/2 study in patients with CD20-expressing non-Hodgkin’s Lymphoma.

• Accelerate  development  of  differentiated Antibody-Drug  Conjugates  (ADCs):  Innate  Pharma  is  advancing  its ADC  programs  to
develop differentiated and highly targeted treatments that combine the specificity of monoclonal antibodies with the potency of cytotoxic
drugs (compounds that induce cancer cell death by interfering with essential cellular functions). IPH4502, Innate’s lead ADC is a novel
and  differentiated ADC  composed  of  an  antibody  targeting  Nectin-4  and  conjugated  to  exatecan,  a  potent  topoisomerase  I  inhibitor,
inducing cell death. IPH4502 is being investigated in a Phase 1 trial in patients with advanced solid tumors.

• Advance current late-stage assets through partnerships: Partnerships will continue to play a critical role in the Company’s strategy,
to aim to have a broader impact with Innate’s established antibody assets, including lacutamab and monalizumab. Innate is actively
seeking a partner to progress lacutamab for patients with advanced forms of T cell lymphomas. Monalizumab, currently in a Phase 3 trial
PACIFIC-9 led by AstraZeneca in non-small cell lung cancer, will see readouts by end of 2026. By entrusting these promising therapies
to strategic partners, Innate seeks to ensure their ongoing development and potential commercialization, with the goal of maximizing
their therapeutic potential and reach.

Activating Innate Immunity: Harnessing the Power of Immunotherapy to Treat Cancer

The Innate Immune System: Gatekeeper of the Adaptive Immune System

The immune system is the body’s defense against invading organisms and pathogens and is comprised of two arms: the innate immune system
and adaptive immune system.

The innate immune system represents the first barrier of immune defense because it reacts almost immediately against threats and serves as a
catalyst  to  mobilize  other  components  of  the  immune  system.  The  innate  immune  system  functions  to  identify,  attack  and  kill  pathogens  or
cancer  cells,  produce  cytokines  and  activate  the  complement  cascade  and  the  adaptive  immune  system  through  antigen  presentation.  These
functions  involve  a  variety  of  cells,  including  NK  cells,  dendritic  cells,  monocytes,  macrophages  and  neutrophils.  These  cells  then  launch
adaptive immune responses while also mounting their own effector responses. Throughout the body, cells of the innate immune system play a
critical role in the immunosurveillance and detection of the formation of cancer cells.

Once  activated,  the  adaptive  immune  system  responds  with  large  numbers  of  effector  cells  directed  against  specific  antigens  and  can  provide
durable immune memory. An adaptive immune response is highly specific to particular antigens expressed by pathogens or cancer cells, but it
requires time to

75

develop in a process known as priming. Key components of the adaptive immune system include antibodies, which are produced by B cells, bind
to antigens and mark them for destruction by other immune cells, and T cells, which recognize antigens on diseased cells and then attack and
eliminate them. The adaptive immune response is targeted and potent and has the potential to provide a long-lasting immune memory.

Harnessing Innate Immunity in Cancer: NK Cells as a Key Player in the Anti-Tumor Immune Response

NK cells are part of the innate immune system and represent a significant fraction of the total number of cytotoxic cells in the body. They are
active in many hematological malignancies (cancers that originate in blood-forming tissues, such as leukemia and lymphoma) and solid tumors
(cancers that develop in solid tissues like the skin and organs) and play a key role in the initiation of the T cell response.

Checkpoints expressed on NK cells include inhibitory cell surface receptors, such as NKG2A (Natural Killer Group 2A, an inhibitory receptor
that suppresses immune cell function upon binding to HLA-E), and activating NK cell receptors, such as NKp46. NKp46 is the most specific NK
cell marker identified to date across organs and species. Other receptors, such as NKG2A, are more prevalent in certain subsets of NK cells,
including NK cells infiltrating the tumor, and are also present on tumor infiltrating CD8  T cells.

+

NK  cells  are  involved  in  the  anti-cancer  immunosurveillance  through  a  variety  of  direct  and  indirect  effects.  The  figure  below  provides  an
illustration of anti-cancer functions of NK cells.

1

2

3

NK cells are able to directly and selectively kill cells
undergoing stress caused by a cancerous transformation
or pathogen infection, a process called natural
cytotoxicity.

NK cells can also kill target cells when they are coated
by antibodies in a process called antibody-dependent
cellular cytotoxicity (ADCC).

NK cells are also potent producers of cytokines, which
are soluble molecules that recruit and activate an
adaptive immune response by T cells through dendritic
or other antigen-presenting cells, which in turn may
enable the generation of immune memory against
tumor cells.

By providing the initial catalyst for the multilayered immune response, the activation of the innate immune system through the targeting of NK
cells could potentially result in an optimal anti-tumoral T cell response.

76

Innate Pharma's response to cancer: harnessing the innate immunity against cancer

The Company has developed a pipeline around two main innovative strategies in modern immuno-oncology:

•

The first of these strategies is to directly target cancer cells through an antibody targeting a tumor antigen and causing its destruction.

◦

◦

◦

Innate's  most  advanced  proprietary  program,  lacutamab,  is  a  potentially  first-in-class  tumor-targeting  antibody  targeting
KIR3DL2, seeking to induce the killing of cells expressing the tumor antigen. The Company is developing lacutamab for the
treatment of various forms of T cell lymphoma (TCL), such as CTCL, including its aggressive subtype, Sézary syndrome, and
PTCL.

The Company has also developed a proprietary technological platform, named ANKET  (for Antibody-based NK cell Engager
Therapeutics),  which  develops  multi-specific  antibody  formats  that  leverage  an  activating  receptor,  NKp46.  Its  multi-specific
antibodies co-engage NKp46, with or without CD16, a tumor antigen and depending on the need, a variant of the interleukin-2
(IL-2v)  molecule. This  approach  has  the  potential  to  more  effectively  mobilize  NK  cells  than  anti-tumor  cytotoxic  antibodies
because, in the tumor's microenvironment (TME) of many solid tumors, CD16, the receptor mediating the killing of tumor cells
by IgG1 antibodies can be downregulated on NK cells whereas NKp46 expression is frequently expressed on tumor-infiltrating
NK cells.

®

The Company is using its antibody engineering capabilities to generate classic antibody formats as well as new products by
exploring antibody drug conjugate (ADC) formats.

• Another strategy, known as immuno-oncology, consists of unleashing the immune system against cancer. Innate Pharma has developed

two approaches:

◦

◦

Checkpoint inhibitors: the development of antibodies that target immune checkpoints has been one of the greatest advances in
cancer treatment over the past 10 years. Notably, the current approved checkpoint inhibitors target the CTLA-4 and PD-1/PD-L1
pathways on T cells. These treatments have shown an ability to activate T cells, shrink tumors and improve patient survival in a
broad  range  of  tumors.  The  Company  is  developing  broad  spectrum  checkpoint  inhibitors  targeting  inhibitory  checkpoints
expressed  on  several  cell  types  in  order  to  potentially  increase  the  breadth  and  quality  of  anti-tumor  response.  Innate's  most
advanced checkpoint inhibitor product candidate, monalizumab, is potentially a first-in-class, dual checkpoint inhibitor designed
to activate both tumor-infiltrating NK cells and CD8  T cells, likely resulting in increased effector functions and greater killing
of the tumor by the immune system. The Company has partnered with AstraZeneca to develop this product, which is currently
being tested in a Phase 3 clinical trial in unresectable, Stage III non-small cell lung cancer (NSCLC) and a Phase 2 clinical trial
in resectable, early-stage NSCLC.

+

Tumor’s  microenvironment  (TME):  the  TME  can  inhibit  both  innate  and  adaptive  immune  responses  either  by  producing  or
degrading key metabolites or by recruiting suppressive cells, or both. For example, adenosine is one of the components of the
TME  that  most  broadly  affects  immune  response.  It  is  produced  by  the  sequential  degradation  of  extracellular  adenosine
triphosphate (ATP) by the following two enzymes: first CD39, which degrades the ATP into adenosine monophosphate (AMP),
and  then  second,  CD73,  which  impairs  the  AMP  into  adenosine.  For  this  reason,  this  pathway  has  attracted  significant
development efforts that have been focused primarily on the downstream part

77

of the adenosine degradation cascade, CD73 and the adenosine receptors. The Company is developing IPH5301, a potentially
best-in-class  anti-CD73  antibody,  and  has  also  focused  on  the  upstream  part  of  the  cascade  through  IPH5201,  an  anti-CD39
antibody,  in  order  to  block  the  production  of  immunosuppressive  adenosine  and  increase  the  pool  of  immuno-stimulatory
extracellular ATP. The Company believes this approach is also potentially mechanistically synergistic with many therapies such
as checkpoint inhibitor, tumor-targeting product, etc., as shown by the results of the COAST randomized Phase 2 study, where
AstraZeneca's  anti-CD73  oleclumab  in  combination  with  durvalumab  improved  progression-free  survival  (PFS)  and  objective
response  rate  (ORR)  compared  to  durvalumab  alone  in  patients  with  unresectable,  Stage  III  non-small  cell  lung  cancer
(NSCLC).  Similarly,  results  from  NeoCoast  randomized  Phase  2  study  showed  that  one  cycle  of  neoadjuvant  oleclumab  in
combination  with  durvalumab  improved  major  pathological  response  (MPR)  and  pathological  complete  response  (pCR)  rates
versus durvalumab alone, in stage I-IIIA resectable NSCLC patients.

Innate Pharma's Product Pipeline

Lacutamab (IPH4102), a Tumor Targeting Anti-KIR3DL2 Antibody

a. Mechanism & Rationale

The Company is developing its wholly owned product candidate lacutamab for the treatment of certain subtypes of T cell lymphoma (TCLs),
including cutaneous T cell lymphoma (CTCL) and peripheral T cell lymphoma (PTCL). Lacutamab is designed to bind to the KIR3DL2 receptor
and to kill cancer cells by antibody dependant cellular phagocytosis (ADCP) and antibody dependant cell cytotoxicity (ADCC), as illustrated in
the following figure.

KIR3DL2  is  a  receptor  of  the  killer  immunoglobulin  like  receptor  (KIR)  family.  In  its  preclinical  studies,  the  Company  has  observed  that
KIR3DL2 is not expressed on healthy tissues, except on a subset of NK cells (36%) and T cells (12% of CD8  and 4% of CD4 ) (IPH internal
data). In addition, KIR3DL2 is expressed in T cell lymphoma: 65% of CTCL patients express KIR3DL2 with approximately 50% of patients
with MF, the most common type of CTCL expressing KIR3DL2 (Battistella, 2017). This

+

+

78

frequency increases for the most aggressive CTCL subtypes, including 90% of Sézary syndrome (Roelens, 2019). Lastly, approximately 50% of
patients with PTCL also express KIR3DL2 (Cheminant, ICML Meeting, 2019).

Indication

i.

Cutaneous T Cell Lymphoma

CTCL  is  a  heterogeneous  group  of  non-Hodgkin’s  lymphomas  that  are  characterized  by  the  abnormal  accumulation  of  malignant  T  cells,
primarily  in  the  skin.  CTCL  accounts  for  approximately  4%  of  all  non-Hodgkin’s  lymphomas  and  has  a  median  age  at  diagnosis  of  55  to  60
years  (Dobos,  2020;  Fuji,  2020). There  are  approximately  2,200-4,000  new  CTCL  cases  diagnosed  per  year  in  Europe  and  the  United  States
combined (SEER Cancer Statistics Review 1975-2017; Dobos, 2020; Zhang, 2019; Gilson, 2019). The most common type of CTCL is mycosis
fungoides,  or  MF,  accounting  for  approximately  half  of  all  CTCLs  (Dobos,  2020,  Bradford,  2009).  Sézary  syndrome,  characterized  by  the
presence of lymphoma cells in the blood, is a CTCL subtype with a particularly poor prognosis. The following table outlines the most common
CTCL  types,  their  frequency  as  a  percentage  of  all  cases  of  CTCL  (Dobos,  2020),  and  the  prognosis  (WHO-EORTC  classification  2018  :

Patients with advanced CTCL have a poor prognosis with few therapeutic options and no standard of care. Treatment generally includes skin-
directed therapies, such as topical corticosteroids, and systemic treatments, such as steroid drugs and interferon, for patients with more advanced
disease or for whom skin-directed therapies failed. There are several approved agents for the treatment of CTCL:

• Bexarotene, approved by FDA in 1999, for use in patients with advanced stage of MF who are refractory to at least one prior systemic

therapy;

• Vorinostat, approved by FDA in 2006 for for the treatment of patients with persistent or recurrent cutaneous T-cell lymphoma (CTCL)
whose  malignant  cells  express  the  CD25  component  of  the  interleukin  (IL)-2  receptor  (CD25+).  However,  ONTAK  was  voluntarily
withdrawn from the U.S. market in 2014. In 2024, "LYMPHIR," also known as "E7777" or "I/ONTAK," a purified and more bioactive
formulation  of  the  previously  FDA-approved  ONTAK®,  was  approved  for  the  treatment  of  adult  patients  with  relapsed  or  refractory
cutaneous T-cell lymphoma (CTCL) in stages I-III, after at least one prior systemic therapy.

• Denileukin diftitox (DD) approved by the FDA in 2008 for patients with resistant and recurrent CTCL;

79

• Romidepsin, approved by FDA in 2009 for patients with CTCL who have received at least one prior systemic therapy;

• Brentuximab vedotin (marketed as Adcetris), was approved by the FDA in 2017 for the treatment of patients with primary cutaneous
anaplastic large cell lymphoma, or pcALCL, or CD30-expressing MF who have received prior systemic therapy. In Europe, brentuximab
vedotin is indicated for the treatment of adult patients with R/R CD30  CTCL who require systemic therapy; and

+

• Mogamulizumab (marketed as Poteligeo), was approved in 2018 by the FDA and the EMA for the treatment of adult patients with R/R

MF or Sézary syndrome after at least one prior systemic therapy.

In  general,  treatment  guidelines  distinguish  CTCL  by  clinical  appearance  and  localization,  histological  subtype,  extent  and  type  of
extracutaneous  disease,  aggressiveness  and  response  to  previous  treatment.  Most  patients  are  not  suitable  for  stem  cell  transplantation  due  to
their age and/or comorbid conditions. Although brentuximab vedotin and mogamulizumab represent recent progress in the treatment of CTCL,
they are still associated with the safety and efficacy limitations observed in their respective clinical trials. Further, even with these options, the
vast  majority  of  these  treated  patients  eventually  relapse  and  the  overall  survival  rate  remains  poor,  which  translates  to  unmet  needs  that
lacutamab aims to address.

In  January  2019,  the  Food  and  Drug  Administration  (FDA)  granted  lacutamab  Fast  Track  Designation  for  the  treatment  of  adults  with
relapsed/refractory (r/r) Sézary syndrome who have received at least two prior systemic therapies. In November 2020, Innate Pharma received
Priority Medicines (PRIME) designation from the EMA for lacutamab, for the treatment of patients with relapsed or refractory Sézary syndrome
(SS) who have received at least two prior systemic therapies. Lacutamab has also been granted orphan drug designation by the FDA and orphan
designation by the EMA for the treatment of CTCL. The U.S. Fast-Track and EU PRIME designations support the potential for lacutamab to
benefit  Sézary  Syndrome  patients  in  need  of  new  treatment  options.  Results  from  the  study  in  Sézary  syndrome  and  mycosis  fungoides  were
presented at the American Society of Hematology (ASH) 2023 Annual Meeting and the American Society of Clinical Oncology (ASCO) 2024
Annual  Meeting  respectively.  Quality  of  life  data  and  translational  analysis  from  the  TELLOMAK  trial  in  patients  with  relapsed/refractory
cutaneous T-cell lymphoma were presented at the ASH Annual Meeting 2024. During the third quarter of 2024, the FDA provided encouraging
initial feedback on the Company’s proposed regulatory pathway, which could potentially include Accelerated Approval for Sézary syndrome, and
the Company continues to align with the FDA around the confirmatory Phase 3 trial.

Separately, in February 2025 the FDA granted Breakthrough Therapy Designation (BTD) to lacutamab, for the treatment of adult patients with
relapsed or refractory (r/r) Sézary syndrome (SS) after at least two prior systemic therapies including mogamulizumab. Breakthrough Therapy
designation is a process designed to expedite the development and review of drugs that are intended to treat a serious condition and preliminary
clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s).

Peripheral T Cell Lymphoma

PTCL is a diverse group of aggressive non-Hodgkin’s lymphomas that develop from mature T cells and NK cells. PTCL arises in the lymphoid

Irrespective  of  the  specific  regimen  used  (single  agent  chemotherapy  or  combination  chemotherapy  including  Gemcitabine  and  Oxaliplatin,
usually  referred  to  as  GemOx),  patients  with  R/R  PTCL  typically  experience  a  poor  outcome,  with  a  median  progression-free  survival  and
overall survival of 3.1 months and 5.5 months, respectively (Mak, 2013).

Multi-agent chemotherapy is the recommended first line treatment for the majority of patients with PTCL. Brentuximab vedotin is approved in
combination  with  first  line  chemotherapy  for  patients  with  CD30-positive  PTCL.  For  patients  who  are  eligible,  subsequent  stem  cell
transplantation is a potentially curative option but it is limited to a minority of patients. Despite these treatments, a high proportion of patients
need second line therapy. Belinostat (marketed as Beleodaq), pralatrexate (marketed as Folotyn) and romidepsin (marketed as Istodax) have each
been  approved  by  the  FDA  in  this  setting,  but  efficacy  is  generally  limited.  In  the  respective  non-randomized  clinical  registration  trials,  the
response rates to belinostat, pralatrexate and romidepsin were each less than 30%, and the median duration of response was approximately 10
months for belinostat and pralatrexate (O'Connor, 2015 ; O'Connor, 2011; Coiffier, 2012). None of these treatments have been approved by the
EMA.

Despite these approvals, current treatment guidelines (NCCN 2021) recommend participation in a clinical trial as a preferred option for patients
with  relapsed  PTCL  after  first  line  treatment.  If  clinical  trials  are  not  available,  a  chemotherapy  combination  of  gemcitabine  and  oxaliplatin
(GemOx) is listed as one of the preferred treatment combinations (European Society for Medical Oncology (ESMO) Lymphoma Guidelines).
Several studies have been published on the role of GemOx in patients with relapsed lymphoma and it is one of the most widely used regimens
for this patient population in the United States, Europe and Asia (Mounier, 2013; Yamaguchi, 2012).

c. Clinical Trials

Below is a summary of the clinical trials of lacutamab.

i.

Phase 1 Clinical Trial - CTCL

In  November  2015,  the  lacutamab  Phase  1  dose-escalating  and  cohort  expansion  clinical  trial  was  initiated  to  evaluate  lacutamab  for  the
treatment of advanced CTCL. Data from this trial were presented at the 2018 meeting of the American Society of Hematology ("ASH"), and
reported in Lancet Oncology in 2019 by Bagot et al. The Company reported clinical activity in the subgroup of 35 Sézary syndrome patients,
including  an  observed  overall  response  rate  of  42.9%,  median  duration  of  response  of  13.8  months,  median  progression-free  survival  of  11.7
months and approximately 90% of patients experienced an improved quality of life. The overall response rate appeared to be higher (53.6%) in
the  28  patients  with  no  histologic  evidence  of  large  cell  transformation.  Clinical  activity  was  associated  with  a  substantial  improvement  in
quality  of  life  as  assessed  by  the  Skindex29  and  Pruritus  Visual Analog  Scale  scores.  In  a  post  hoc  analysis  of  seven  patients  with  Sézary
syndrome who were previously treated with mogamulizumab, three (43%) achieved a global overall response and three others had stable disease
as  best  response.  The  remaining  patient  had  a  progressive  disease.  The  median  duration  of  response  in  these  patients  was  13.8  months  and
median progression-free survival was 16.8 months. Lacutamab was generally well tolerated.

ii.

Phase 2 Clinical Trial (TELLOMAK) - CTCL

1.

Study overview

In May 2019, the Company initiated a global, open-label, multi-cohort Phase 2 clinical trial, known as TELLOMAK. This clinical trial is being
conducted at approximately 50 sites within the United States and Europe (France, Italy, Spain, Germany, Belgium, Poland and Austria). The trial
aims  to  evaluate  the  efficacy  and  safety  of  lacutamab  in  patients  with  advanced  T  cell  Lymphoma.  160  patients  have  been  recruited,
approximately  60  patients  with  Sézary  syndrome  who  have  received  at  least  two  prior  treatments  (Cohort  1),  and  approximately  100  patients
with MF who have received at least two prior systemic therapies (Cohorts 2, 3 and all-comers). Cohorts 2 and 3 recruited KIR3DL2 expressing
and  non-expressing  patients  respectively  based  on  an  IHC  assay  for  use  on  frozen  tissue.  The  cohorts  were  designed  using  Simon  2-stage
approach which pre-defined an efficacy threshold in Stage 1 before continuing to stage 2. While Cohort 2 continues to Stage 2, the pre-specified
threshold for Cohort 3 was not met, and was therefore closed in March 2022.

In March 2022, the Company announced the opening of a new mycosis fungoides (MF) all-comers cohort in the TELLOMAK study. The all-
comers cohort was planned to recruit both KIR3DL2 expressors and

82

non-expressors to explore the correlation between the level of KIR3DL2 expression and treatment outcomes utilizing a formalin-fixed paraffin
embedded (FFPE) assay as a companion diagnostic.

The following graphic depicts the latest trial design :

The primary endpoint of the trial is objective response rate, measured using the 2011 Olsen criteria for CTCL. Key secondary measures include
incidence  of  treatment-emergent  AEs,  the  effect  of  skin  disease  on  quality  of  life  as  measured  by  the  Skindex29  questionnaire,  pruritus  as
measured by the Visual Analog Scale, progression-free survival and overall survival. The results of the dedicated Sézary syndrome cohort may
support a future Biologics License Application (BLA) submission to the FDA.

The study started in 2019 and completed enrollment in June 2023 (n=170 patients).

The TELLOMAK study experienced some supply issues within 2019/2020 which led to a clinical hold, now resolved and summarized below:

• November 2019, Impletio Wirkstoffabfüllung GmbH (formerly known as Rentschler Fill Solutions GmbH), the subcontractor in charge of the
fill-and-finish  manufacturing  operations  of  lacutamab  unilaterally  decided  to  withdraw  the  certificates  of  conformance  of  all  clinical  batches
produced at their facilities, including lacutamab. The company also filed for bankruptcy.

•  Discussions  were  held  with  US  and  European  national  regulatory  authorities  regarding  GMP  deficiencies  resulting  in  a  suspension  of
enrollment of new patients into TELLOMAK from December 2019.

•  In  January  2020,  the  TELLOMAK  trial  in  Sézary  syndrome  and  MF  in  France  and  in  the  United  Kingdom,  was  reactivated  following
authorization by the respective national authorities. In June 2020, the FDA lifted the partial clinical hold placed on the TELLOMAK Phase 2
clinical  trial,  based  on  a  quality  assessment  of  a  new  GMP-certified  batch  successfully  manufactured  for  the  lacutamab  clinical  development
program, including the TELLOMAK trial. Regulatory agencies in Spain, Germany and Italy also lifted, in the third quarter of 2020, their partial
clinical holds on the TELLOMAK trial, enabling Innate to resume recruitment of the trial in these countries.

Importantly, there were no safety issues related to the trial medication. This is consistent with the review conducted by the Independent Data
Monitoring Committee (IDMC), which concluded there were no safety issues related to lacutamab, and the product appeared to be well-tolerated
among current patients enrolled in the trial. Lacutamab fill and finish manufacturing operations were transferred to alternative CMOs

In October 2023, the FDA placed a partial clinical hold on the lacutamab IND leading to a pause in new patient enrollment to the Company’s
lacutamab  trials  IPH4102-201  (Phase  2  TELLOMAK)  and  102  (Phase  1b  PTCL).  The  partial  clinical  hold  followed  one  fatal  case  of
hemophagocytic  lymphohistiocytosis,  a  rare  hematologic  disorder.  In  January  2024,  Innate  announced  that  the  U.S.  Food  and  Drug
Administration (FDA) has lifted the partial clinical hold. The FDA decision to lift the partial clinical hold is based on the FDA review of the fatal
case which Innate, together with a steering committee of independent experts, determined to be related to aggressive disease progression and
lacutamab unrelated.

83

Based on the results of a planned futility interim analysis, however, and in consultation with FDA, the Phase 1b study will not enroll additional
patients. Despite objective responses observed, the Company-sponsored Phase 1b clinical trial evaluating lacutamab as monotherapy in patients
with KIR3DL2-expressing refractory/relapsing PTCL will not be reopened to recruitment as the prespecified threshold for meaningful clinical
activity was not reached.

2.

Clinical results in Sézary Syndrome (SS) (Cohort 1)

•

Final results from the Phase 2 TELLOMAK study in Sézary Syndrome were presented at the ASH Meeting in December 2023.

◦ As of May 1, 2023, the study’s data cutoff, patients in the Sézary Syndrome cohort (cohort 1, n=56) received a median of five

prior systemic therapies, including mogamulizumab, and had a median follow-up of 14.4 months.

◦

The  data  demonstrated  that  lacutamab  showed  robust  clinical  activity  and  an  overall  favorable  safety  profile.  The  global
confirmed objective response rate (ORR), was 37.5% (21 out of 56), including two complete responses and 19 partial responses.
ORR in the skin was 46.4% (26 out of 56), including five complete responses and 21 partial responses and ORR in the blood
was 48.2% (27 out of 56) with 15 CR and 12 PR. Median progression-free survival was 8.0 months (95% confidence interval
4.7-21.2). In patients who achieved a global response, the median duration of response is 12.3 months (95% confidence interval
5.1-NE).

•

In  February  2025,  Innate  announced  that  the  U.S.  Food  and  Drug Administration  (FDA)  granted  Breakthrough  Therapy  Designation
(BTD) to lacutamab, an anti-KIR3DL2 cytotoxicity-inducing antibody, for the treatment of adult patients with relapsed or refractory (r/r)
Sézary syndrome (SS) after at least 2 prior systemic therapies including mogamulizumab.

◦

The BTD is granted based on Phase 1 study results as well as results from the Phase 2 TELLOMAK study, where lacutamab
demonstrated  encouraging  efficacy  and  a  favorable  safety  profile  in  heavily  pretreated,  post-mogamulizumab  patients  with
advanced Sézary syndrome.

◦ A BTD by the FDA is intended to accelerate the development and regulatory review in the U.S. of drugs that are intended to
treat  a  serious  condition  and  that  have  shown  encouraging  early  clinical  results,  which  may  demonstrate  substantial
improvement on a clinically significant endpoint over available medicines.

◦

Innate continues to align with the regulatory agencies around the confirmatory Phase 3 trial in CTCL and is actively seeking a
partner.

Interim clinical results in mycosis fungoides (MF)

•

•

•

•

In  February  2021,  the  Company  announced  that  lacutamab  demonstrated  a  positive  early  signal  in  Cohort  2  testing  lacutamab  in
KIR3DL2  expressing  MF  patients  in  the  TELLOMAK  trial.  This  cohort  reached  the  pre-determined  number  of  responses  needed  to
advance to stage 2, allowing the Company to recruit additional patients.

The preliminary data from cohorts 2 and 3 were presented at the ICML and EORTC congresses in July and October 2021 respectively.

In September 2022, MF Cohorts 2 and 3 Stage 1 interim data were presented at the EORTC congress. As of the March 4, 2022 data
cutoff:

◦

◦

Patients in the KIR3DL2 ≥1% subgroup (cohort 2) received a median of four prior systemic therapies, and had a median follow-
up of 12.2 months. Objective response rate (ORR) was 28.6% (95% CI 13.8-50.0) including two complete responses and four
partial responses. Median PFS was 12.0 months (4.6-15.4) and Median Duration of Response was 10.2 months (4.6-NA).

Patients in the KIR3DL2 <1% subgroup (cohort 3) received a median of 4.5 prior systemic therapies and had a median follow-
up of 13.8 months. ORR was 11.1% (3.1-32.8) with a median PFS of 8.5 months (4.1-NA)

◦ Within the advanced and heavily pre-treated population enrolled in TELLOMAK, Lacutamab continues to demonstrates clinical

activity with a favorable safety profile.

◦

Lacutamab showed low immunogenicity and reached target concentration in both the KIR3DL2 expressing and non-expressing
patients.

In 2023, MF Cohorts 2 and 3 interim efficacy results according to updated guidelines were presented at the International Conference on
Malignant  Lymphoma  and  EORTC  Cutaneous  Lymphoma  Tumour  Group  Annual  Meeting  congresses  in  June  and  October  2023,
respectively.

85

◦ As of the March 4, 2022 data cutoff, patients in the KIR3DL2-expressing MF cohort (cohort 2, n=21) received a median of 4
prior systemic therapies, and had a median follow-up of 12.2 months. In the KIR3DL2 non-expressing cohort (cohort 3, n=18),
patients received a median of 4.5 prior systemic therapies and had a median follow-up of 13.8 months.

◦

Lymph  Node  assessment  is  an  important  component  of  staging  and  response  assessment  in  CTCL  (cutaneous  T  cell
lymphomas). In a recent update to the Olsen 2011 guidelines, it was clarified that the pathological assessment of lymph nodes be
limited  to  those  that  satisfy  nodal  lymphoma  i.e.  N3  designation  (Olsen  2021).  Based  on  these  criteria,  results  showed  that
lacutamab produced an increased global objective response rate (ORR) of 42.9% (95% confidence interval [CI], 24.5-63.5) in
patients  with  KIR3DL2  ≥  1%  MF  (cohort  2,  n=21),  including  2  complete  responses  and  7  partial  responses.  Clinical  Benefit
Rate remained unchanged at 85.7% [95% CI tbc]. In Cohort 3, comprising 18 patients with KIR3DL2 < 1% MF, findings remain
unchanged.

•

In 2024, favorable results from the Phase 2 TELLOMAK study with lacutamab in mycosis fungoides (MF) were presented at the ASCO
2024

◦ As  of  October  13,  2023,  data  cutoff,  MF  patients  (n=107)  received  a  median  of  4  prior  systemic  therapies  and  had  a  median

follow-up of 11.8 months.

◦

The  data  demonstrated  that  treatment  with  lacutamab  resulted  in  meaningful  antitumor  activity,  regardless  of  the  KIR3DL2
baseline expression, and an overall favorable safety profile. The global objective response rate (ORR) was 16.8% (Olsen 2011)
and 22.4% (Olsen 2022), including 2 complete responses (CR) and 16 partial responses (PR). In patients expressing a baseline
KIR3DL2 ≥ 1%, the ORR was 20.8% (Olsen 2011) and 29.2% (Olsen 2022). Median progression-free survival was 10.2 months
(95% CI 6.5, 16.8) for all MF patients and 12.0 months (95% CI 5.6, 20.0) in the KIR3DL2 ≥ 1% group. Time to response was
1.0 month (95% CI 1, 5).

iii.

Clinical Trials in PTCL

• Despite objective responses observed, the Company-sponsored Phase 1b clinical trial evaluating lacutamab as monotherapy in patients
with KIR3DL2-expressing refractory/relapsing PTCL will not be reopened to recruitment as the prespecified threshold for meaningful
clinical activity was not reached.

• At the ASH Annual Congress 2023, Innate presented a poster with preclinical data demonstrating a synergistic effect between lacutamab

and chemotherapy in preclinical models of PTCL, supporting the rationale for combination strategy in this clinical indication.

•

The  Phase  2  KILT  (anti-KIR  in  T  Cell  Lymphoma)  trial,  an  investigator-sponsored,  randomized  trial  led  by  the  Lymphoma  Study
Association (LYSA) to evaluate lacutamab in combination with chemotherapy GEMOX (gemcitabine in combination with oxaliplatin)
versus GEMOX alone in patients with KIR3DL2-expressing relapsed/refractory PTCL is ongoing.

Monalizumab, a Dual Checkpoint Inhibitor Targeting T Cells and NK Cells

a. Mechanism & Rationale

86

+

Monalizumab (IPH2201) is a potentially first-in-class immune checkpoint inhibitor targeting NKG2A receptors expressed on tumor infiltrating
cytotoxic CD8  T cells and NK cells. NKG2A is an inhibitory receptor for HLA-E (Human Leukocyte Antigen-E). HLA-E is a non-classical
MHC class I molecule that plays a in immune regulation. In cancer, HLA-E is frequently overexpressed allowing tumor cells to evade immune
attack by engaging NKG2A and suppressing the activity of cytotoxic immune cells. Monalizumab may reestablish a broad anti-tumor response
mediated by NK and T cells, and may enhance the cytotoxic potential of other therapeutic antibodies (André et al., Cell 2018).

b. Rationale for combinations with monalizumab

The Company is primarily focused on investigating monalizumab in combination with durvalumab, which is an antibody directed against PD-L1
(Programmed Death-Ligand 1). PD-L1 is an immune checkpoint protein expressed on the surface of many cancer cells that binds to PD-1 on T
cells,  suppressing  their  activity  and  preventing  an  effective  immune  response.  By  inhibiting  PD-L1,  durvalumab  restores  T  cell  function,
enhancing the immune system’s ability to recognize and attack tumor cells. Both PD-L1 and HLA-E are frequently overexpressed on cancer cells
and contribute to immune evasion by binding to their respective inhibitory receptors, PD-1 and NKG2A. Innate Pharma's preclinical data support
its hypothesis that a monalizumab and durvalumab combination therapy may result in a greater anti-tumor immune response than durvalumab
alone by blocking both the PD-1/PD-L1 and the NKG2A/HLA-E inhibitory pathways.

The following illustration depicts the way in which monalizumab, in combination with durvalumab, is designed to result in greater anti-tumor
activity.

The  rationale  for  this  combination  is  further  supported  by  the  favorable  tolerability  profile  of  monalizumab  that  the  Company  observed  in
preclinical  studies  and  earlier  clinical  trials,  suggesting  that  monalizumab  is  generally  not  expected  to  negatively  impact  the  safety  profile  of
combination partner drugs.

c. Clinical Development Plan and results

i.

Overview

87

Monalizumab has been evaluated in clinical trials in head and neck, lung and other cancer indications. Innate was responsible for the conduct of
the IPH2201-203 study in head and neck squamous cell carcinoma (study completed), while AstraZeneca is conducting all other trials (except for
the  External  Sponsored  studies).  External  Sponsored  studies  are  currently  ongoing  in  bladder  cancer  and  small  cell  lung  cancer.  Below  is  a
summary of ongoing clinical trials in NSCLC that AstraZeneca is conducting to evaluate monalizumab:

Lung cancer is the leading cause of cancer death, accounting for about one-third of all cancer deaths. In 2020, an estimated 2.2 million
people  were  diagnosed  with  lung  cancer  worldwide.  Eighty  to  eighty-five  percent  are  classified  as  NSCLC.  Stage  III  NSCLC  represents
approximately one quarter of NSCLC incidence. In 2018, the FDA approved durvalumab for patients with unresectable stage III NSCLC whose
disease  has  not  progressed  following  concurrent  platinum-based  chemotherapy  and  radiation  therapy.  However,  there  is  still  a  need  for  new
treatment  options  to  further  increase  the  potential  for  cure  in  this  setting.  AstraZeneca  conducted  COAST,  a  randomized  Phase  2  trial
investigating  durvalumab  alone  or  in  combination  with  either  oleclumab  (anti-CD73  monoclonal  antibody)  or  monalizumab  (anti-NKG2A
monoclonal antibody) in patients with locally advanced, unresectable Stage III NSCLC who had not progressed after chemoradiotherapy (CRT).
Following  on  the  signal  observed  in  this  Phase  2  study, AstraZeneca  has  started  a  randomized  Phase  3  study  PACIFIC-9  of  monalizumab  or
oleclumab  plus  durvalumab  in  unresectable,  Stage  III  NSCLC  setting  for  patients  who  have  not  progressed  after  concurrent  chemoradiation
therapy.

Separately, AstraZeneca evaluated the effectiveness and safety of neoadjuvant durvalumab alone or in combination with monalizumab or
oleclumab in subjects with resectable, early-stage (Stage I [>2 cm] to IIIA) non-small cell lung cancer (NeoCOAST) and in 2022 initiated the
Phase 2 trial, NeoCOAST-2, with neoadjuvant and adjuvant treatment, that includes an arm with durvalumab in combination with chemotherapy
and monalizumab.

In head and neck cancer, Innate and AstraZeneca evaluated monalizumab in combination with cetuximab in R/M SCCHN IO naïve or
IO-pretreated in a Phase 1b/2 study (IPH2201-203). Based on the results and the unmet need in the IO-pretreated population, AstraZeneca and
Innate  elected  to  advance  this  program  to  a  Phase  3  study  (INTERLINK-1).  Dosing  of  the  first  patient  in  this  trial  triggered  a  $50  million
milestone  payment  from  AstraZeneca  to  Innate  in  October  2020.  In  2022,  Innate  announced  that  a  planned  futility  interim  analysis  of  the
INTERLINK-1  Phase  3  study  sponsored  by  AstraZeneca  did  not  meet  a  pre-defined  threshold  for  efficacy.  Based  on  this  result  and  the
recommendation of an Independent

88

Data Monitoring Committee, AstraZeneca informed Innate that the study would be discontinued. There were no new safety findings.

ii.Lung Cancer: Phase 2 COAST Study

In September 2021, AstraZeneca presented a late-breaker abstract on the randomized COAST Phase 2 trial in patients with unresectable, Stage
III  non-small  cell  lung  cancer  (NSCLC)  at  the  European  Society  for  Medical  Oncology  (ESMO)  Congress.  The  presentation  highlighted
progression-free  survival  (PFS)  and  overall  response  rate  (ORR)  results  for  durvalumab  in  combination  with  monalizumab,  Innate’s  lead
partnered  asset,  and  oleclumab,  AstraZeneca’s  anti-CD73  monoclonal  antibody.  After  a  median  follow-up  of  11.5  months,  the  results  of  an
interim analysis showed a 10-month PFS rate of 72.7% for durvalumab plus monalizumab, versus 39.2% with durvalumab alone in unresectable,
Stage III NSCLC patients following chemoradiation therapy. The results also showed an increase in the primary endpoint of confirmed ORR for
durvalumab plus monalizumab over durvalumab alone (36% vs. 18%). Data are published in the Journal of Clinical Oncology in 2022 (figure
below).

At ASCO 2024, AstraZeneca presented an update on the trial results. After a median follow-up of 30.1 months, the findings showed a 12-month
progression-free  survival  rate  of  73.2%  for  durvalumab  plus  monalizumab,  compared  to  37.6%  for  durvalumab  alone.  The  results  also
demonstrated an increase in the primary endpoint, confirmed overall response rate, for durvalumab plus monalizumab versus durvalumab alone
(40.3% vs. 23.9%).

iii.

Lung Cancer: Phase 2 NeoCOAST Study

In March 2022, the Phase 2 NeoCOAST multi-drug platform study assessing the safety and efficacy of neoadjuvant durvalumab in combination
with chemotherapy and oleclumab, monalizumab or danvatirsen and adjuvant treatment in participants with resectable, early-stage non-small cell
lung  cancer  was  accepted  for  an  oral  presentation  on  April  11,  2022  at  the  Annual  Meeting  2022  of  the  American  Association  for  Cancer
Research  (AACR).”  The  study  demonstrated  that  a  single  cycle  of  neoadjuvant  durvalumab  combined  with  oleclumab,  monalizumab,  or
danvatirsen  produced  numerically  improved  MPR  rates  (19,  30  and  31.2%,  respectively)  compared  with  durvalumab  alone  (11.1%).  No
differences in pCR rates were observed between treatment arms.

iv.

Lung Cancer: Phase 3 PACIFIC-9

In June 2023, AstraZeneca presented at the ASCO conference a trial-in-progress poster on the PACIFIC-9 study: "Phase 3 study of durvalumab
combined with oleclumab or monalizumab in patients with unresectable stage III NSCLC (PACIFIC-9)."

PACIFIC-9 started in February 2022 and continues to enroll patients.

In 2024, the Independent Data Monitoring Committee recommended the continuation of the Phase 3 PACIFIC-9 trial based on a pre-planned
analysis.

v.

Lung Cancer: Phase 2 NeoCOAST-2

In June 2023, AstraZeneca presented at the ASCO conference a trial-in-progress poster on the NeoCOAST-2: study: "NeoCOAST-2: A Phase 2
study of neoadjuvant durvalumab plus novel immunotherapies (IO) and chemotherapy (CT) or MEDI5752 (volrustomig) plus CT, followed by
surgery

89

and adjuvant durvalumab plus novel IO or volrustomig alone in patients with resectable non-small-cell lung cancer (NSCLC)."

NeoCOAST-2 started in April 2022 and continues to enroll patients.

AstraZeneca  presented  interim  results  from  the  randomized  NeoCOAST-2  (NCT05061550)  Phase  2  platform  study  during  the  2024  World
Conference on Lung Cancer on September 8, 2024.

The preliminary data of three arms were presented at WCLC, namely:

• Arm 1: oleclumab in combination with durvalumab and platinum doublet chemotherapy in the neoadjuvant setting and durvalumab plus

oleclumab in the adjuvant setting;

• Arm 2: monalizumab in combination with durvalumab and platinum doublet chemotherapy in the neoadjuvant setting and durvalumab

plus monalizumab in the adjuvant setting and;

• Arm 4: datopotamab deruxtecan in combination with durvalumab and single agent platinum chemotherapy in the neoadjuvant setting,

and durvalumab alone in the adjuvant setting.

In this preliminary analysis on the first 60 of 72 patients randomized to Arm 2, monalizumab added to durvalumab plus platinum-based
chemotherapy doublet induced a pathological complete response rate of 26.7% [95% CI; 16.1–39.7] and a major pathological response rate of
53.3% [95% CI; 40.0–66.3] which are numerically higher than the durvalumab plus platinum doublet approved regimen. Treatment in Arm 2
showed manageable safety profile and no impact on surgical rate.

d.

Partnership with AstraZeneca

Further  to  a  first  co‑development  and  commercialization  agreement  with  AstraZeneca  to  accelerate  and  broaden  the  development  of
monalizumab,  AstraZeneca  obtained  full  oncology  rights  to  monalizumab  in  October  2018.  The  financial  terms  of  the  agreement  include
potential  cash  payments  of  up  to  $1.275  billion  to  Innate  Pharma. With  the  addition  of  the  $50  million  payment  triggered  by  dosing  the  first
patient in the Phase 3 PACIFIC-9 clinical trial, Innate Pharma has received $450 million to date. AstraZeneca will book all sales and will pay
Innate low double-digit to mid-teen percentage royalties on net sales worldwide except in Europe where Innate Pharma will receive if it chooses
to co-promote the licensed products in certain European countries a 50% share of the profits and losses in these territories. Should Innate Pharma
elect not to co-promote, its share of profits in Europe will be reduced by a specified amount of percentage points not to exceed the mid-single
digits.  Innate  will  co-fund  30%  of  the  costs  of  the  Phase  3  development  program  of  monalizumab  with  a  pre-agreed  limitation  on  Innate’s
financial commitment.

Multi-specific  monoclonal  antibodies,  or  multi-specifics,  are  antibody-derived  formats  that  can  simultaneously  bind  to  two  or  more  different
types  of  molecules. A  number  of  studies  of  bispecific  antibodies  are  currently  underway,  such  as  those  assessing  the  safety  and  efficacy  of
bispecific T cell engagers (BiTEs), which engage T cells via the antigen receptor on one side of the bispecific T cell engager, and a tumor antigen
on the other side of the BiTE. These molecules have demonstrated the ability to reduce or slow the growth of tumors in cancer patients, but they
also carry a significant toxicity risk. This toxicity risk occurs by engaging all T cells, irrespective of their specificity and development status,
potentially leading to an over production of cytokines by these T cells, referred to as a cytokine

90

storm.  In  parallel,  bispecific  killer  cell  engagers  (BiKEs)  that  engage  CD16  receptors  found  on  NK  cells,  and  tri-specific  killer  cell  engagers
(TriKEs) that engage CD16 receptors and contain IL-15, a cytokine that promotes NK cell activation and survival, have also been developed to
target  antigens  expressed  on  solid  tumors.  BiKEs  and  TriKEs  can  be  effective  both  in  vitro  and  in  vivo  in  preclinical  models.  These  multi-
specific molecules that engage NK cells could reduce the risks associated with toxicity, as NK cell counts represent only approximately 10% of
T cell counts, thereby potentially limiting the likelihood of inducing a cytokine storm. However, it remains unclear whether these multifunctional
CD16 engager antibodies can activate NK cells in solid tumors since solid tumors often express low levels of CD16.

ANKET   (Antibody-based  NK  cell  Engager Therapeutics)  is  Innate’s  proprietary  platform  for  developing  next-generation,  multi-specific  NK
cell engagers to treat certain types of cancer.

This versatile, fit-for-purpose technology is creating an entirely new class of molecules to induce synthetic immunity against cancer. It leverages
the advantages of harnessing NK cell effector functions against cancer cells and also provides proliferation and activation signals targeted to NK
cells.

Innate's  latest  innovation  in  the ANKET   platform,  the  tetra-specific ANKET   molecule,  is  the  first  NK  cell  engager  technology  to  engage
activating receptors (NKp46 and CD16), a tumor antigen and an interleukin (IL)-2 receptor (via an IL-2 variant, IL-2v) via a single molecule.
This innovation is built on its existing tri-specific NK cell engager technology, which has demonstrated potent NK cell activation, cytotoxicity
and efficient control of tumor growth in preclinical models.

®

®

Because NKp46 is expressed on all NK cells and conserved on tumor infiltrating NK cells, and NK cells are not expected to produce a cytokine
storm, ANKET  molecules may overcome the limitations of both ADCC-inducing antibodies and T cell engagers.

IPH6101/SAR'579, a CD123-targeting NK Cell Engager

a. Mechanism

®

IPH6101/SAR443579  is  the  first  trifunctional  anti-CD123  NK  cell  engager  NKp46/CD16  using  Innate’s  proprietary  multi-specific  antibody
format ANKET . It has shown anti-tumor activity in preclinical models, including supporting pharmacokinetic/pharmacodynamic (PK/PD) and
safety  data  in  non-human  primate  studies,  leading  to  its  selection  as  a  drug  candidate  for  development.  IPH6101  was  part  of  a  non-exclusive
intellectual property license granted to Sanofi under the 2016 research collaboration and license agreement, pursuant to which the companies
collaborated on the development of innovative multi-specific antibody formats engaging NK cells through the activating receptors NKp46 and
CD16  to  kill  tumor  cells.  Several  NK  cell  therapies  have  been  shown  to  induce  antitumor  responses,  without  the  complications  frequently
associated with T cell therapies, such as cytokine release syndrome (CRS) or neurotoxicity.

b.

Indication and Rationale

Acute myeloid leukemia (AML) is the most common acute leukemia in adults, mostly affecting elderly patients, with a median age at diagnosis
of 65-70 years. AML is a heterogeneous cancer characterized by the clonal expansion of myeloid precursors in the bone marrow and peripheral
blood. Despite significant progress in the care of AML patients in the past decade, there is still a clear unmet medical need in AML, as up to 50%
of patients relapse after initial chemotherapy, and the prognosis for older patients remains poor.

Cytotoxic  antibodies  targeting  CD123  displayed  limited  antileukemic  activity  in  several  clinical  trials,  even  when  tested  in  the  form  of  Fc-
engineered antibodies designed specifically to increase antibody-dependent cell cytotoxicity (ADCC). By contrast, T cell engager molecules and
CAR-T  cell  therapies  have  some  clinical  efficacy,  but  are  also  highly  toxic,  confirming  the  need  for  alternative  targeted  approaches  for  the
treatment  of AML.  NK  cell-based  therapies  may  provide  new  treatment  perspectives  and  a  safer  alternative  for  targeting  tumor  cells  in  this
context.

c. Preclinical Development

In  its  preclinical  studies,  Innate  and  Sanofi  investigated  whether  NKp46-based  NKCE  technology  could  provide  more  effective  antitumor
activity than regular IgG antibodies for AML treatment by generating a NKCE molecule targeting CD123. Innate and Sanofi evaluated the ex
vivo antitumor activity of this molecule, comparing it with a regular IgG1 antibody derived from clone 7G3 (CD123-IgG1 ) with an engineered
Fc domain for enhanced ADCC.

+

The anti-CD123 antibody-mediated killing of primary blasts from AML patients (AML#1 to AML#4) was evaluated ex vivo with NK cells from
healthy donors as effectors. The anti-CD123 antibody (CD123-IgG1 ) mediated the killing of blasts from half the patient samples (AML#1 and
AML#2)  but  was  barely  active  against  blasts  from  the  other  half  of  the  primary  samples  (AML#3  and AML#4).  The  patient  samples  could
therefore be separated into two distinct groups: CD123-IgG1 responders and CD123-IgG1 non-responders.

+-

+-

+

Innate  and  Sanofi  observed  that  trifunctional  CD123-ANKET   displayed  killing  activity  against  all  primary  malignant AML  cells,  promoting
significant  antitumor  activity  in  CD123-IgG1 non-responders  samples  from  AML  patients  against  which  the  regular  anti-CD123  cytotoxic
antibody was completely inactive.

The minimal level of pro-inflammatory cytokine release following the treatment of human peripheral blood mononuclear cells (PBMCs) with
NKCE  in  vitro  (data  not  shown)  was  further  confirmed  in  vivo,  in  dedicated  pharmacokinetic  (PK),  pharmacodynamic  (PD)  and  toxicology
studies performed in non-human primates (NHPs).

Innate and Sanofi evaluated the PK/PD of CD123-NKCE administered by a single one-hour i.v. infusion of a high (3 mg/kg) or low (3 µg/kg)
doses in male cynomolgus monkeys (two animals each for the 3 mg/kg and 3 µg/kg doses). Treatment with CD123-NKCE promoted a sustained
and complete depletion of CD123  cells in the blood of all monkeys, for more than 10 days, at both the 3 mg/kg and 3 µg/kg doses, with only
very small amounts (< 50 pg/mL) of the pro-inflammatory cytokines IL-6 and IL-10 released without any associated clinical signs.

d. Ongoing Clinical Trial

•

Phase 1/2 clinical trial monotherapy

IPH6101/SAR443579  is  currently  being  evaluated  in  a  Phase  1/2  clinical  trial  (NCT05086315)  in  patients  with  relapsed  or  refractory  acute
myeloid leukemia (R/R AML), B-cell acute lymphoblastic leukemia (B-ALL) or high risk-myelodysplastic syndrome (HR-MDS).

The  purpose  of  the  dose  escalation  and  dose  expansion  study,  which  is  sponsored  by  Sanofi,  is  to  evaluate  the  safety,  pharmacokinetics,
pharmacodynamics  and  initial  clinical  activity  of  IPH6101/SAR443579,  Innate’s  lead  ANKET   asset,  in  various  CD123-expressing
hematological malignancies.

®

Innate Pharma announced that the first patient was dosed on December 16, 2021.

▪

▪

In June 2023, safety and preliminary efficacy were presented during an oral presentation at the ASCO Meeting. Preliminary data showed
SAR443579 / IPH6101 was well tolerated and induced three complete responses in the eight patients at 1 mg/kg as the highest dose. In
addition, Innate Pharma shared Sanofi’s news that the FDA has granted Fast Track Designation for SAR’579 / IPH6101 for the treatment
of hematological malignancies.

In October 2023, a preliminary Pharmacokinetics (PK) and Pharmacodynamic (PD) Analysis of the CD123 NK Cell Engager
SAR’579/IPH6101 in patients with relapsed or refractory AML, B-ALL or HR-MDS was presented at the ESMO congress.

In December 2023, updated efficacy and safety results were shared in a poster presentation at the ASH Annual Meeting. Abstract details
included:

• As of July 5, 2023, 43 patients (42 R/R AML and one HR-MDS) across eight dose levels at 10 – 6000 μg/kg/dose were included.

Patients had received a median of 2.0 (1.0 – 10.0) prior lines of treatment with 13 patients (30.2%) reporting prior
hematopoiectic stem cell transplantation and 36 patients (83.7%) with prior exposure to venetoclax.

•

In dose levels with a highest dose of 1000 μg/kg QW, 5 out of 15 (33.3%) AML patients achieved a complete remission, or CR,
(4 CRs and 1 CR with incomplete hematological recovery) as of the cut-off date.

• Data from preliminary pharmacokinetics / pharmacodynamic and in vitro mechanistic analyses studying dose-response relations

were also presented.

94

•

SAR443579 was well tolerated up to doses of 6000 μg/kg QW with observed clinical benefit in patients with R/R AML. The
results are consistent with the predicted favorable safety profile.

Updated efficacy and safety results were presented at the European Hematology Association 2024

•

Fifty-nine patients (58 R/R AML and 1 HR-MDS) across 11 dose levels (0.01 – 6mg/kg) were treated. Patients had received a median of
2 (1 – 10) prior lines of treatment. A maximum response rate was observed at a final target dose of 1 mg/kg every week with 5 AML
patients achieving a CR (4 CR/1 CRi)1. The median treatment duration was 7.9 weeks, with durable CR (>10 months) observed in 3
patients with 2 remaining on maintenance therapy as of the data cutoff. SAR’579 was well tolerated up to doses of 6 mg/kg every week.
These data will form the basis for selection of recommended doses for development in the Phase 2 portion of the trial.

In April 2024, Sanofi advanced SAR’579 / IPH6101 to the Phase 2 preliminary dose expansion of the trial evaluating NK Cell Engager
SAR443579/ IPH6101 in various blood cancers. Under the terms of the 2016 research collaboration with Sanofi, the progression to the
dose expansion part of the trial has triggered a milestone payment from Sanofi to Innate of €4 million. This amount was received by the
Company on May 17, 2024.

Phase 1/2 clinical trial in combination

•

In  July  2024,  Sanofi  initiated  a  new  Phase  1  /  Phase  2,  randomized,  open  label,  multi-cohort,  multi-center  study  (NCT06508489)
assessing  the  safety,  tolerability  and  preliminary  efficacy  of  SAR’579  /  IPH6101  administered  in  combination  with  azacitidine  and
venetoclax in patients with CD123 expressing hematological malignancies in newly diagnosed AML.

On April 23, 2025, the Company announced that, as part of the restructuring of the January 2016 Research Collaboration and License Agreement
(the  “2016  Agreement”)  and  in  alignment  with  both  company's  current  strategic  priorities,  Sanofi  and  Innate  agreed  to  terminate  the  2016
Agreement as it relates to SAR’579/IPH6101 (CD123 ANKET), effective as of June 30, 2025. Innate will regain the rights on July 1, 2025. The
Parties will discuss a transition plan with regard to ongoing studies

IPH6401/SAR’514, a BCMA-targeting NK Cell Engager

a.

Mechanism

BCMA (B-Cell Maturation Antigen) is a protein expressed on the surface of mature B cells and plasma cells. It is essential for B cell survival
and function. In multiple myeloma and other B-cell malignancies, BCMA is overexpressed on malignant plasma cells.

IPH6401/SAR’514 is a trifunctional anti-BCMA NKp46xCD16 NK cell engager, using Sanofi’s proprietary CROSSODILE® multi-functional
platform, which comprises the Cross-Over-Dual-Variable-Domain (CODV) format. It induces a dual targeting of the NK activating receptors,
NKp46 and CD16, for an optimized NK cell activation, based on Innate’s ANKET  (Antibody-based NK cell Engager Therapeutics) proprietary
platform.

A  Sanofi-sponsored  Phase  1/2  clinical  trial  (NCT05839626)  is  evaluating  SAR’514  /  IPH6401  in  relapsed/refractory  Multiple  Myeloma
(RRMM)  and  Relapsed/Refractory  Light-chain  Amyloidosis  (RRLCA).  The  purpose  of  the  dose  escalation  and  dose  expansion  study  is  to
evaluate the safety, pharmacokinetics and preliminary efficacy of SAR’514 in monotherapy in patients with RRMM and RRLCA. The clinical
trial is part of the Sanofi 2016 research collaboration and licensing agreement.

As  a  reminder,  the  Company  announced  that,  in  2023,  the  first  patient  was  dosed  in  a  Sanofi-sponsored  Phase  1/2  clinical  trial  evaluating
IPH6401/SAR'514 in RRMM. As provided by the licensing agreement signed in 2016, Sanofi made a milestone payment of €2.0 million, fully
recognized in revenue as of June 30, 2023. This amount was received by the Company on July 21, 2023.

The Company announced on March 27, 2025, that the clinical study will be terminated early as SAR’514/IPH6401 will now be pursued in
autoimmune indications.

IPH6501, a CD20-targeting tetra-specific NK Cell Engager

a. Mechanism

The  IPH6501  program  is  developing  a  CD20-targeting  tetra-specific Antibody-based  NK  cell  Engager  Therapeutics  (ANKET ).  CD20  is  an
antigen  expressed  by  a  number  of  B  cell  malignancies,  and  its  targeting  by  therapeutic  antibodies  has  shown  efficacy  to  treat  the  patients
although a number of the tumors develop resistance and relapse. Compared to a classical IgG1-based antibody which engages Fc receptors and a
tumor  antigen,  IPH6501  co-engages  on  one  hand  NKp46  and  Fc  receptors,  as  well  as  CD122  subunit  of  the  IL-2  receptor  (but  not  CD25
subunit), and on the other hand CD20 as a targeted

®

96

antigen on malignant B cells, leading to potent NK cell activation, cytotoxicity and control of tumor growth.

IPH6501 was designed to induce NK cell mediated-cytotoxicity and cytokine secretion by co-engaging CD16a and NKp46. Only the binding of
IPH6501 to CD20, bridging the NK cells to the target cells, was able to trigger the cytotoxic activity of NK cells. IPH6501 is thus a promising
biologic designed to harness the anti-tumor functions of NK cells in CD20  B cell malignancies.

+

Moreover, the IL-2R binding element incorporated in IPH6501 is an IL-2 variant (IL-2v) designed with point mutations that abolish binding to
the IL-2R-α chain (CD25), with the goal of limiting toxicity and interaction with Tregs. IL-2v incorporated into IPH6501 is directed towards NK
cells through the binding with high affinity to NKp46 and CD16a, providing its ability to interact with IL-2R preferentially on NK cells and to
promote their activation and proliferation at pM doses.

b.

Indication and Rationale

IPH6501 is being developed in patients with relapsed or refractory (R/R) CD20  B-cell non-Hodgkin's lymphomas (NHL).

+

NHL is the most prevalent hematological malignancy, accounting for 4% of all new cancer cases and 3% of cancer-related deaths in the United
States (Howlader 2020a, Howlader 2020b). For 2021, estimates for the United States include 81,560 new cases and 20,720 deaths from NHL
(American  Cancer  Society  2021a, American  Cancer  Society  2021b).  In  2020,  Europe  had  122,979  new  cases  of  NHL  reported,  and  49,684
deaths  were  attributable  to  NHL  (World  Health  Organization  (WHO)  2020). The  emergence  of  relapsed  refractory  (r/r)  disease  among  B-cell
malignancies with curtailed sustained responses to treatment and unattained long-term survivals has created a significant unmet need (National
Comprehensive Cancer Network (NCCN) 2021a).

CD20  is  expressed  by  >90%  of  B-cell  non-Hodgkin's  lymphomas  (NHL).  Several  generations  of  CD20-targeting  monoclonal  antibodies
including rituximab, ofatumumab, and obinutuzumab have been widely used for B-cell malignancy therapies. Despite the recent approvals of
novel CD20-targeting agents, new alternatives and strategies are still required for patients, which are relapsing or refractory after several lines of
treatment. High circulating NK cell numbers have been associated with better clinical responses

97

to anti-CD20-targeting monoclonal antibodies, supporting the role of NK cells in efficacy of these treatments.

c. Preclinical Development

IPH6501 preclinical activity was explored both in vitro and in vivo. In vitro studies established that IPH6501´s main modes of action were NK
cell proliferation and antibody-dependent cell cytotoxicity (ADCC) against CD20-expressing cells.

•

In vitro

Non-saturating doses of IPH6501 on NK cells and on CD20  cells were sufficient to promote maximal killing activity. Furthermore, IPH6501
promoted NK cell cytotoxicity against tumor cells expressing very low levels of CD20. IPH6501 also demonstrated superiority to control tumor
cell growth in vitro, as compared to the CD20-targeting clinical benchmark antibodies rituximab and the Fc-optimized obinutuzumab.

+

+
IPH6501 alone without NK cells did not induce direct killing of CD20  cells. Culturing human purified NK cells with CD20  B-lymphoma cell
lines and IPH6501 induced the specific lysis of tumoral CD20  cells. Alternatively, culturing human PBMCs with IPH6501 induced the specific
depletion of normal CD20  B lymphocytes without affecting other lymphocyte population numbers, as well as cytokine production in line with
NK  cell  activation.  Incubation  of  human  PBMC  with  IPH6501  induced  a  preferential  NK  cell  proliferation  that  occurred  at  lower  doses  as
+
compared to the proliferating effect of IPH6501 on other CD8  or CD4  T lymphocytes (expressing the IL-2R).

+

+

+

+

•

In vivo

In vivo treatment with a mouse surrogate of IPH6501 induced peripheral NK cell proliferation and activation, and demonstrated potent antitumor
efficacy  in  a  xenograft  mouse  model  using  the  aggressive  human  B-lymphoma  CD20   RAJI  cell  line  engrafted  subcutaneously.  Surrogate
moIPH6501 also showed

+

98

a  dose  dependent  and  significant  control  of  tumor  growth  in  a  model  of  CD20-expressing  B16F10  cells  injected  intravenously  (IV)  in
immunocompetent mice, as shown in figure below.

Updated preclinical data were presented at the European Hematology Association (EHA) congress in June 2023, including experiments on non-
human  primates  and  samples  from  R/R  B-NHL  patients.  In  preclinical  settings,  IPH6501  was  shown  to  induce  NK  cell  proliferation  and  to
trigger  high  NK  cell  cytoxicity  against  CD20+  target  cells  in  in  vitro  assays,  in  ex  vivo  assays  with  relapse/refractory  (R/R)  B-NHL  patient
samples  who  received  at  least  one  prior  treatment,  as  well  as  in  in  vivo  studies  in  non-human  primates. A  surrogate  of  IPH6501  mediated  a
potent anti-tumor activity in vivo in CD20+ tumor models in mice. In addition, in ex vivo assays with R/R B-NHL patient samples, IPH6501
was shown to be more efficient than a T cell engager targeting CD20.

• Non-human primates

In non-human primates, a well-tolerated dose of IPH6501 resulted in NK cell expansion, with minimal increase in systemic cytokine levels, and
to the depletion of CD20+ B cells in circulation and lymphoid tissues.

• Analysis from samples from R/R B-NHL patients

Flow cytometric analysis of samples from R/R B-NHL patients revealed that NK cell numbers in blood were within normal range values, and
NKp46 expression was maintained in blood and tumor-involved lymph nodes. Of note, in contrast to NKp46, cell surface expression of CD16
was  down-regulated  on  NK  cells  in  B-NHL  patient’s  lymph  nodes,  suggesting  a  potential  therapeutic  advantage  of  targeting  NKp46  with
IPH6501 in B-NHL compared with classical monoclonal antibodies. IPH6501 stimulated NK cell

99

proliferation  and  CD20+  cell  depletion  ex  vivo  in  PBMC  samples  from  R/R  B-NHL  patients,  which  compared  favourably  with  acontrol
CD3xCD20 T cell engager.

In  2024,  new  preclinical  data  supporting  the  development  of  IPH6501  were  presented  at  the  SITC,  EHA,  and  EHA  conferences  with  the
following key messages:

•

•

•

•

IPH6501 expand and mobilize peripheral NK cells for tumor killing: IPH6501 mouse surrogate potently induces NK cells activation,
proliferation and recruitment from the periphery to the tumor microenvironment in mouse models

IPH6501 advantage over antibody-based CD20- T cell engagers:

◦ Higher efficacy in depleting autologous CD20 B cells in PBMC from HD and from R/R B-NHL patients (leukemic phase

disease)

◦ Reduced induction of pro-inflammatory cytokines compared to a CD20-TCE in PBMCs from HD.

IPH6501 advantage over antibody-based CD20-targeting therapies: NK cells from B-NHL patients lymph nodes express low levels of
CD16 while NKp46 is maintained

IPH6501 has applications across subtypes of B-NHL, and potential in post CAR-T setting:

◦

◦

◦

IPH6501 targets (NKp46, CD16, IL-2Rβ) are expressed on blood NK cells

IPH6501 shows potent in vitro antitumor activity on patient PBMCs

Post-lymphodepletion NK recovery (Piperoglou et al., 2021, J. Leuk. Biol) supports IPH6501 potential in post CAR-T patients.

IPH6501  is  a  first-in-class  CD20-targeting  tetra-specific  NK  cell  engager  designed  to  promote  NK  cell  proliferation  and  specific  cytotoxicity
against  CD20   cells.  IPH6501  is  thus  a  promising  biologic  designed  to  harness  the  anti-tumor  functions  of  NK  cells  in  CD20   B  cell
malignancies.

An 

On March 6, 2024, the Company announced that the first patient was dosed in its Phase 1/2 multicenter trial (NCT06088654), investigating the
safety and tolerability of IPH6501 in patients with Relapsed and/or Refractory CD20-expressing B-cell non-Hodgkin’s lymphoma. The study is
ongoing and planned to

100

enroll up to 184 patients. Clinical sites are open in the US, Australia and France and the first safety and preliminary activity data are expected in
late 2025.

A poster on the design of the ongoing trial was presented at ASCO 2024.

In December 2024, the Company has entered into an agreement to clinically study the potential of IPH6501, Innate's anti-CD20 ANKET® in
follicular  lymphoma  (FL)  with  the  Institute  for  Follicular  Lymphoma  (IFLI)  under  which  Innate’s  ongoing  Phase  1/2,  open-label,  multicenter
trial investigating the safety, tolerability, and preliminary antineoplastic activity of IPH6501 in patients with relapsed and/or refractory CD20-
expressing Non-Hodgkin Lymphoma will include patients with relapsed / refractory (R/R) FL.

To support the Phase 1/2 trial and inclusion of FL patients, IFLI initially invested $3 million into new shares of Innate, issued through a capital
increase reserved to IFLI at a price of €1.56 per share and representing 2.26% of the share capital of Innate at the time of issuance. IFLI may also
invest up to an additional $4.9 million into new shares of Innate, depending on the completion of certain milestones, at a price to be determined
at the time of such investments.

IPH45 is a novel and differentiated topoisomerase I inhibitor ADC conjugated to exatecan targeting Nectin-4

IPH43, an anti-MICA/B ADC.

b. Proprietary : IPH4502

1. Rationale

Nectin-4 is overexpressed in multiple solid tumors with high medical need, but is expressed at low levels in some epithelia, including the skin,
bladder, breast duct, and placenta. Enfortumab vedotin (EV), a Nectin-4-targeting antibody-drug conjugate (ADC) with a monomethyl auristatin
E (MMAE) payload, has been approved for the treatment of urothelial carcinoma (UC), which exhibits highest Nectin-4 expression. To treat
cancers with lower levels of Nectin-4 and improve the balance between efficacy and safety, we developed IPH4502. IPH4502 delivers a cancer-
killing drug, exatecan, with a drug-to-antibody ratio (DAR) of 8.

2.    Preclinical data

The preclinical data on IPH4502, a next-generation ADC targeting Nectin-4 and conjugated to exatecan, were presented at the 2024 AACR and
SITC conferences.

101

–

–

–

Strong bystander effect in vivo and high internalization efficiency in vitro compared to other Nectin-4-targeting ADCs. These
characteristics contribute to enhanced anti-tumor activity compared to EV across a broad range of Nectin-4 expression levels, from low
to high, in PDX models.

Superior efficacy to EV in bladder cancer models with low Nectin-4 expression.

Potential beyond bladder cancer in tumors with low and heterogeneous Nectin-4 expression: Leveraging its bystander activity, IPH4502
is active in tumor models with low and heterogeneous Nectin-4 expression beyond UC.

– Activity in models with primary or acquired resistance to EV: IPH4502 demonstrates efficacy in an in vivo model with primary

resistance to MMAE due to MDR1 transporter expression and shows anti-tumor activity in a PDX model of UC with acquired resistance
to EV.

–

Strong combination potential with PD-1-targeting agents: In syngeneic mouse models, the combination of IPH4502 with an anti-PD-1
antibody induces synergistic anti-tumor activity in both EV-sensitive and EV-resistant models.

– Hydrophilic and stable linker enables high ADC exposure and minimal free exatecan release in cynomolgus monkey plasma.

The activity of IPH45 in various indications and its enhanced anti-tumor activity in combination with anti-PD-1 therapies in preclinical models
support its development beyond UC.

The Phase 1, open-label, multi-center study, includes a Part 1 Dose Escalation and a Part 2 Dose Optimization, and will assess the safety,
tolerability, and preliminary efficacy of IPH4502 as a single agent in advanced solid tumors known to express Nectin-4, including but not limited
to urothelial carcinoma, non-small cell lung, breast, ovarian, gastric, esophageal, and colorectal cancers.

The U.S Food and Drug Administration (FDA) cleared its investigational new drug (IND) application to initiate a Phase 1 clinical study of
IPH4502 in September 2024 and the first patient was dosed in its Phase 1 study (NCT06781983) in January 2025.

The study is recruiting and plans to enroll approximately 105 patients.

c. Former Partner

Innate announced in April 2023 that it granted Takeda exclusive worldwide rights to research and develop ADC using a panel of selected Innate
antibodies against an undisclosed target, with a primary focus in Celiac disease.

102

Takeda would have been responsible for the future development, manufacture and commercialization of any potential products developed using
the licensed antibodies.

Under the terms of the license agreement, Innate has received an upfront payment of $5 million and would have been eligible to receive up to
$410 million in future development, regulatory and commercial milestones if all milestones are achieved during the term of the agreement, plus
royalties on potential net sales of any commercial product resulting from the license. Takeda made a strategic decision to terminate the license
agreement  executed  in  March  2023  for  use  of  selected  Innate  antibodies  in  antibody  drug-conjugates.  Innate  has  regained  full  rights  to  these
antibodies during the last quarter of 2024. The Company does not intend at this stage to continue the development of these antibodies.

IPH5201, an Anti-CD39 Antibody Targeting the Immunosuppressive Adenosine Pathway

a Mechanism & Rationale

CD39 is an extracellular enzyme that is expressed in the tumor microenvironment, on both tumor infiltrating cells and stromal cells in several
cancer types. CD39 inhibits the immune system by degrading adenosine triphosphate (ATP) into adenosine monophosphate (AMP), that is then
further  degraded  into  adenosine  by  CD73.  By  promoting  the  accumulation  of  immune-stimulating  ATP,  and  preventing  the  production  of
immune-suppressive adenosine, the blockade of CD39 may stimulate anti-tumor activity.

IPH5201 is a blocking antibody targeting the CD39 immunosuppressive pathway.

Targeting the adenosine pathway has recently been reported to improve Durvalumab (anti-PD-L1) efficacy in early-stage Non-Small Cell Lung
Cancer (NSCLC) patients, through the use of Oleclumab, an anti-CD73 monoclonal antibody. Indeed, in the COAST randomized Phase 2 study,
oleclumab  in  combination  with  durvalumab  improved  progression-free  survival  (PFS)  and  objective  response  rate  (ORR)  compared  to
durvalumab  alone  in  patients  with  unresectable,  Stage  III  non-small  cell  lung  cancer  (NSCLC)  (Herbst,  JCO,  2022). Also,  in  the  NeoCoast
randomized Phase 2 study, one cycle of neoadjuvant oleclumab in combination with durvalumab improved major pathological response (MPR)
and pathological complete response (pCR) rates versus durvalumab alone, in stage I-IIIA resectable NSCLC patients (Cascone, AACR 2022).

This supports the evaluation of the combined blockade of CD39 and PD-L1, with IPH5201 and durvalumab, respectively, that can hypothetically
increase activity when compared to durvalumab monotherapy by altering the balance of ATP and adenosine in the tumor microenvironment.

 Clinical development

1. Overview and indications

IPH5201 has been evaluated in a Phase 1 clinical in advanced solid tumors, in monotherapy and in combination with durvalumab; and is being
investigated in a Phase 2 clinical trial, MATISSE, in combination with durvalumab and chemotherapy in non-small cell lung cancer (NSCLC).

Lung cancer is the second most common cancer in both men and women, with an estimated 234,030 new cases of lung cancer in the United
States  in  2018,  and  remains  the  main  cause  of  cancer-related  deaths  worldwide.  Resectable,  early‑stage  NSCLC  is  considered  a  potentially
curable disease, and the standard of care is surgery alone or surgery with adjuvant or neoadjuvant platinum‑based doublet chemotherapy (NCCN
2022). However, patients had five‑year survival rates ranging from approximately 70% for Stage IA1 NSCLC to 20% for Stage IIIA NSCLC
(Chansky, 2017).

Recently, the role of PD-1/PD‑L1 inhibition has been evaluated for the treatment of resectable, early‑stage NSCLC in adjuvant and neoadjuvant
setting  and  led  to  improved  outcomes  and  recent  approval  (Nivolumab/Checkmate  816  and  Pembrolizumab/KEYNOTE-671).  Recent  interim
data from the Phase III AEGEAN study (NCT03800134) showed that perioperative durvalumab (anti-PD-L1) plus neoadjuvant CT significantly
improved both pathological complete response (pCR) rate (17.2% in the durvalumab-based regimen arm vs 4.3% in the CT arm) and Event-Free
Survival (EFS) (median not reached in the durvalumab-based regimen arm vs 25.9 months in the CT arm) in patients with resectable, Stage IIA–
IIIB[N2] NSCLC.

1. Phase I in advanced solid tumors

A  Phase  1  clinical  trial  (NCT04261075),  sponsored  by AstraZeneca,  with  first  patient  treated  in  March  2020,  evaluated  IPH5201,  an
anti-CD39 blocking monoclonal antibody, in adult patients with advanced solid tumors. The purpose of the study was to evaluate IPH5201 as
monotherapy  and  in  combination  with  durvalumab  (anti-PD-L1)  and  with  or  without  oleclumab  (anti-CD73  monoclonal  antibody).  This
multicenter,  open-label,  dose-escalation  Phase  1  study  evaluated  the  safety,  tolerability,  antitumor  activity,  pharmacokinetics  (PK),
pharmacodynamics (PD) and immunogenicity of IPH5201 alone, or in combination with AstraZeneca’s anti-PD-L1 therapy, durvalumab, with or
without its anti-CD73 monoclonal antibody, oleclumab.

IPH5201 was well tolerated when used alone or in combination with durvalumab up to a dose of 3000 mg Q3W. The safety profile was
manageable, with the most common treatment-related adverse events being infusion-related reactions and fatigue; no new safety signals were
identified beyond those observed with durvalumab monotherapy. No maximum tolerated dose (MTD) was identified. PK of IPH5201 was non-
linear at ≤300 mg and linear at ≥1000 mg. The PD profile, including inhibition of

104

CD39 activity in the tumors of patients treated with IPH5201, was consistent with the proposed mechanism of action for IPH5201.

As clinical activity results, 22/57 patients (38.6%) had stable disease as their best overall response; there were no partial or complete responses.
In IPH5201 monotherapy subgroup, 17/38 patients (44.7%) had stable disease as their best overall response

1. Phase II MATISSE study in NSCLC

MATISSE  is  a  Phase  2  multicenter  single-arm  study  (NCT05742607),  sponsored  by  Innate  Pharma,  evaluating  neoadjuvant  and  adjuvant
treatment  with  IPH5201,  an  anti-CD39  blocking  monoclonal  antibody,  in  combination  with  durvalumab  (anti-PD-L1)  and  chemotherapy,  in
treatment-naïve  patients  with  resectable  early  stage  non-small  cell  lung  cancer  (NSCLC).  The  primary  objectives  of  the  study  are  to  assess
antitumor activity of neoadjuvant treatment based on pathological complete response (pCR) and safety. Innate is responsible for conducting the
study and shares study costs with AstraZeneca. AstraZeneca supplies clinical trial drugs.

The first patient was dosed in June 2023. In October 2023, Innate Pharma presented at the ESMO conference a trial-in-progress poster on the
MATISSE  study:  "A  Phase  II  multicenter,  open  label,  non-randomized  study  of  neoadjuvant  and  adjuvant  treatment  with  IPH5201  and
durvalumab in patients with resectable, early-stage (II to IIIA) non-small cell lung cancer (MATISSE)."

a

Partnership

On  October  22,  2018,  Innate  Pharma  and  AstraZeneca  entered  into  the  2018  AZ  Option  Agreement  for  further  co-development  and  co-
commercialization of IPH5201. Following the dosing of the first patient on March 9, 2020, in the IPH5201 Phase 1 clinical trial, AstraZeneca
made a $5 million milestone

105

payment to Innate under the collaboration and option agreement relating to IPH5201. Innate made a €2.7 million milestone payment to Orega
Biotech SAS after the dosing of the first patient in the Phase 1 pursuant to Innate’s exclusive licensing agreement from Orega Biotech SAS (see
“Item 10C.—Material Contracts”) and an arbitral decision rendered in December 2021 relating to milestone payments received by the Company
under  the  2018 AZ  Option Agreement.  For  more  information,  see  Note  6  to  the  consolidated  financial  statements  included  under  "Item  18.
Financial Statements" of this Annual Report.

In  June  2022,  the  2018  IPH5201  Option Agreement  was  amended.  Innate  received  a  $5  million  milestone  payment  from AstraZeneca  upon
signature  of  the  amendment  and  is  responsible  for  conducting  a  Phase  2  multicenter,  open  label,  non-randomized  study  of  neoadjuvant  and
adjuvant treatment with IPH5201, durvalumab, and chemotherapy in patients with resectable, early-stage non-small cell lung cancer (NSCLC).
The "MATISSE" Study has started and is recruiting patients. AstraZeneca and Innate will share study costs and AstraZeneca will supply clinical
trial drugs. Innate made a €0.6 million milestone payment to Orega Biotech SAS pursuant to Innate’s exclusive licensing agreement.

IPH5301, an Anti-CD73 Antibody Targeting the Immunosuppressive Adenosine Pathway

a Mechanism & Rationale

Targeting the pathway that metabolizes adenosine triphosphate (ATP) to adenosine in the tumor microenvironment is an emerging therapeutic
strategy  to  promote  antitumor  immunity  (Di  Virgilio  et  al.,  2018,  Leone  et  al.,  2018,  Vijayan,  2017).  Within  the  tumor  microenvironment,
extracellular ATP  is  released  by  dying  cells  and  has  an  immune-stimulatory  activity,  promoting  activation  of  antigen  presenting  cells,  and  a
subsequent  immune  response  (de Andrade  Mello  et  al.,  2017;  Ghiringhelli  et  al.,  2009). The  extracellular  enzyme  CD39  hydrolyses ATP  into
adenosine  diphosphate  (ADP)  and  adenosine  monophosphate  (AMP)  in  the  extracellular  space,  and  CD73  ectonucleotidase  (NT5E,  ecto-5’-
nucleotidase)  further  metabolizes  AMP  to  adenosine  (Allard,  2016).  Adenosine  exerts  immunosuppressive  effects  on  both  the  myeloid  and
lymphoid  compartments  (de Andrade  Mello  et  al.,  2017).  In  T  cells,  adenosine  inhibits  effector  T  cell  activation,  induces  T  cell  anergy  and
expands T regulatory cells (Ehrentraut et al., 2012; Romio et al., 2011; Zarek et al., 2008). Finally, adenosine inhibits NK cell-mediated tumor
cell lysis (Beavis et al., 2013).

The benefit of targeting CD73 in oncology has been further demonstrated by results of the COAST randomized Phase 2 study, where anti-CD73
oleclumab  in  combination  with  durvalumab  improved  progression-free  survival  (PFS)  and  objective  response  rate  (ORR)  compared  to
durvalumab alone in patients with unresectable, Stage III non-small cell lung cancer (NSCLC) (Herbst, JCO, 2022), as well as in results from
NeoCoast randomized Phase 2 study showing that one cycle of neoadjuvant oleclumab in combination with durvalumab improved MPR (Major
Pathological Response) and pCR (pathological Complete Response) rates versus durvalumab alone, in stage I-IIIA resectable NSCLC patients
(Cascone, AACR 2022).

The Company is developing IPH5301 (anti-CD73) as a potential anticancer therapy for patients with advanced or metastatic disease in selected
solid tumors. IPH5301 is a monoclonal antibody that selectively binds to and inhibits the activity of both membrane-bound and soluble human
CD73 (NT5E, ecto-5’-nucleotidase).

IPH5301 inhibits CD73-mediated hydrolysis of adenosine monophosphate (AMP) to adenosine. CD73 has been shown to be expressed by tumor
cells as well as stromal cells, endothelial cells and B and T lymphocytes within the tumor microenvironment, and it has been shown to play a
significant role in promoting immunosuppression through the pathway degrading AMP into adenosine. Therefore, inhibition of CD73‑mediated
hydrolysis of AMP by IPH5301 has the potential to reduce the formation of

106

immunosuppressive adenosine, thereby leading to increased antitumor immunity across multiple tumor types, as shown in the figure below.

a

Indication

In the tumor microenvironment, CD73 is expressed by tumor cells as well as stromal cells, endothelial cells and B and T lymphocytes (Allard et
al., 2017). Inhibition of CD73 enzymatic activity by IPH5301 has the potential to reduce the formation of immunosuppressive adenosine, thereby
leading to increased antitumor immunity across multiple tumor types.

a

Preclinical Development

The  Company  published  preclinical  data  further  supporting  the  rationale  of  developing  IPH5301.  IPH5301  blocked  the  enzymatic  activity  of
both CD73 expressed at the cell surface and the soluble form of CD73. IPH5301 was able to efficiently restore T cell proliferation inhibited by
AMP in vitro. In addition, IPH5301 has been observed to have a differentiated and superior activity compared to benchmark antibodies that are
currently in clinical development (Perrot, 2019).

Thus,  IPH5301  could  potentially  exhibit  a  favorable  efficacy  profile  in  patients  with  advanced  or  metastatic  disease  in  selected  solid  tumors,
including serving as a candidate for combination treatments with chemotherapy or immune therapeutic agents.

As further evidence for the negative role of CD73 in anti-tumor response, Loi et al., 2013, examined gene expression data from 6,000 breast
cancer patients and found that high CD73 expression was associated with poor prognosis in triple-negative breast cancer (TNBC), as was the
association  between  high  CD73  gene  expression  and  pre-surgery  treatment  with  the  standard  of  care  chemotherapy  anthracycline.  In  mice
inoculated with the syngeneic 4T1.2 breast tumor cell line, a combination of an anti-CD73 antibody and doxorubicin (an anthracycline) led to a
greater reduction in tumor volume and increase in mouse survival than either treatment alone.

In HER2-positive breast tumors, high CD73 expression was shown to promote resistance to trastuzumab. In addition, targeting CD73 was shown
to  enhance  efficacy  of  treatment  with  anti-HER2  therapy  (Turcotte,  2017).  On  the  other  hand,  several  chemotherapeutic  agents  including
taxanes, anthracyclines and platinum salts were shown to increase the release of ATP (Martins and Tesniere, 2009); (Martins and Wang, 2014).

All together, these preclinical results indicate that CD73 blockade with IPH5301 has also the potential to enhance antitumor activity observed
with not only PD1 immunotherapy, but also with chemotherapy and trastuzumab.

i. Ongoing Clinical Trial

In December 2021, an investigator-sponsored Phase 1 trial of IPH5301 was initiated by the Institut Paoli-Calmettes. CHANCES-IPC 2021-008
(NCT05143970) is a First In Human, Phase 1, multicenter, European study evaluating an anti-CD73, IPH5301, in advanced and/or metastatic
cancer. The trial will be conducted in two parts. The Part I-Dose escalation aims to identify the maximum tolerated dose (MTD) of IPH5301
agent in monotherapy and recommended Phase 2 dose (RP2D) for future trials, followed by a safety expansion study part cohort. In the Part II-
Expansion cohort, a total of 12 HER2+

107

cancer patients, respectively six breast cancer patients and six gastric cancer patients, are planned to be enrolled into the next expansion cohort to
select a recommended dose of IPH5301 to be administered in combination with chemotherapy and trastuzumab for evaluation in future trials
with selected advanced solid tumors. In March 2022, The Institut Paoli Calmettes announced that the first patient had been dosed. In December
2022, a "Trial in Progress" poster was presented by the Institut Paoli Calmettes at ESMO-IO 2022 congress (Goncalvez, ESMO-IO 2022, Poster
199, abstract 290). This trial is ongoing.

At the ESMO Conference in September 2024, preliminary results were presented, indicating that IPH5301 was was safe and well-tolerated with
preliminary signals of monotherapy antitumor activity.

Next Steps for Clinical Trials

Competition

The  biotechnology  and  pharmaceutical  industry,  and  notably  the  cancer  field,  is  characterized  by  rapidly  advancing  technologies,  products
protected by intellectual property rights and intense competition and is subject to significant and rapid changes as researchers learn more about
diseases and develop new technologies and treatments. While the Company believes that its technology, knowledge, experience, collaborations
and  scientific  resources  provide  Innate  with  competitive  advantages,  the  Company  faces  potential  competition  from  many  different  sources,
including  major  pharmaceutical,  specialty  pharmaceutical  and  biotechnology  companies,  academic  institutions,  governmental  agencies  and
public and private research institutions. Any approved product that Innate Pharma commercializes will compete with existing therapies and new
therapies that may become available in the future.

A  large  number  of  companies  are  developing  or  marketing  treatments  for  cancer,  including  many  major  pharmaceutical  and  biotechnology
companies.  Many  of  their  competitors  have  significantly  greater  experience,  personnel  and  resources  as  they  relate  to  research,  drug
development,  manufacturing  and  marketing.  In  particular,  large  pharmaceutical  laboratories  have  substantially  more  experience  than  the
Company  does  in  conducting  clinical  trials  and  obtaining  regulatory  authorizations.  Mergers  and  acquisitions  in  the  pharmaceutical,
biotechnology  and  diagnostic  industries  may  result  in  even  more  resources  being  concentrated  among  a  smaller  number  of  its  competitors.
Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and
established companies. These competitors are also likely to compete with Innate to recruit

108

and retain top qualified scientific and management personnel, acquire rights for promising product candidates and technologies, establish clinical
trial  sites  and  patient  registration  for  clinical  trials,  acquire  technologies  complementary  to,  or  necessary  for,  its  programs  and  enter  into
collaborations with potential partners who have access to innovative technologies.

Innate's commercial opportunity could be reduced or eliminated if its competitors develop and commercialize products that are more effective,
have a better safety profile, are more convenient, have a broader label, have more robust intellectual property protection or are less expensive
than any products that the Company may develop. Its competitors also may obtain regulatory approval for their products more rapidly than the
Company may obtain approval for its products, which could result in its competitors establishing a strong market position before the Company is
able to enter the market. In addition, its competitors could be more efficient in manufacturing or more effective in marketing their own products
than the Company or its partners may be in the future.

With respect to its lead product candidate, lacutamab, a monoclonal antibody product candidate targeting KIR3DL2, the Company is aware of
several  pharmaceutical  companies  marketing  and  developing  products  for  the  treatment  of  patients  with  CTCL,  including  MF  and  Sézary
syndrome, and PTCL. The latest drugs approved by the FDA for CTCL are: In 2024, LYMPHIR, also known as E7777 or I/ONTAK, a purified
and more bioactive formulation of the previously FDA-approved ONTAK®, was approved for the treatment of adult patients with relapsed or
refractory cutaneous T-cell lymphoma (CTCL) at stages I-III, after at least one prior systemic therapy. Adcetris (brentuximab vedotin), marketed
by  Seattle  Genetics  and  approved  in  combination  with  chemotherapy  for  treatment  of  patients  with  primary  cutaneous  anaplastic  large  cell
lymphoma (pcALCL) or CD30-expressing MF who have received prior systemic therapy, and Poteligeo (mogamulizumab), marketed by Kyowa
Kirin  and  approved  for  the  treatment  of  adult  patients  with  R/R  MF  or  Sézary  syndrome  after  at  least  one  prior  systemic  therapy.  Zolinza
(vorinostat)  is  the  only  drug  approved  by  the  FDA  for  CTCL  patients  after  two  prior  failures.  In  the  second  line  setting  of  PTCL,  Beleodaq
(belinostat), Folotyn (pralatrexate) and Istodax (romidepsin) have all been approved by the FDA; however, none of these treatments have been
approved by the EMA.

With respect to monalizumab, a novel dual-targeting checkpoint inhibitor, other anti-NKG2A have started to be assessed in clinical trials, and
several  pharmaceutical  companies  are  marketing  and  developing  treatments  for  either  NSCLC.  Currently  two  ongoing  clinical  trials  are
assessing other anti-NKG2A molecules. A Phase 1/2 study is assessing S095029 (Servier) monotherapy or in combination with an anti-PD-1 in
patients  with  solid  tumors  with  dose  expansion  cohorts  that  add  an  anti-HER2  or  anti-EGFR  to  the  doublet. A  Phase  1  study  is  evaluating
BRY805 (BioRay Pharmaceutical Co.) as monotherapy in patients with solid tumours. A Phase 1/2 trial evaluating BMS-986315 (Bristol-Myers
Squibb) as a monotherapy or in combination with nivolumab or cetuximab in patients with solid tumors has been completed. Exelis and Invenra
are collaborating to develop a bispecific targeting PD-L1 and NKG2A which is in the preclinical setting.

There are also several pharmaceutical and biotechnology companies that are focused on the tumor microenvironment, including the complement
and the adenosine pathways. AstraZeneca has an anti-CD73, Oleclumab, in Phase 3 in the PACIFIC-9 trial, in which Monalizumab is also being
evaluated.  I-Mab  (Ulidlimab)  and  Arcus  Biosciences  (Quemliclustat)  also  have  CD73  inhibitors  in  clinical  development.  Several  other
companies are developing CD39 inhibitors, including Trishula Therapeutics (TTX-030), Arcus Biosciences (AB598), and Elpiscience (ES002).

NK cells have been increasingly researched and the Company is aware of several companies activating and /or harnessing NK cells to target and
kill cancer cells through different approaches such as cell therapies (for example, Fate Therapeutics, Inc. and NKarta, Inc., Century Therapeutics)
and multi-specifics (for example, Affimed N.V. and Dragonfly Therapeutics, Inc.).

109

The development of antibody-drug conjugates (ADCs) in oncology is highly competitive, with numerous companies investing in this therapeutic
approach to improve the efficacy and selectivity of cancer treatments. Nectin-4 (N4) is garnering increasing interest due to its high expression in
several solid tumors, including urothelial carcinoma. To date, only one Nectin-4-targeting ADC has been commercialized (Enfortumab Vedotin,
PADCEV®). Several Nectin-4-targeting ADCs conjugated with MMAE are in advanced stages of development, such as candidates from Bicycle
and Mabwell. Additionally, new ADCs using topoisomerase inhibitors as cytotoxic payloads are being developed, with early-stage programs in
the U.S. and Europe, and more advanced phases in China (Hengrui). In this competitive landscape, IPH4502 offers differentiated perspectives in
terms of therapeutic index and potential benefit for patients with low Nectin-4 expression. Its strategic development aims to address the
limitations of existing ADCs and optimize the treatment of Nectin-4-expressing cancers.

Intellectual Property

Commercial  success  of  the  Company  depends  in  part  on  obtaining  and  maintaining  patent,  trade  secret  and  other  intellectual  property  and
proprietary protection of its technology, current and future products and product candidates and methods used to develop and manufacture them.
The Company cannot be sure that patents will be granted with respect to any of its pending patent applications or to any patent applications filed
by Innate in the future, nor can the Company be sure that any of its existing patents or any patents that may be granted to Innate in the future will
be sufficient to protect its technology or will not be challenged, invalidated or circumvented. Its success also depends on its ability to operate its
business  without  infringing,  misappropriating  or  otherwise  violating  any  patents  and  other  intellectual  property  or  proprietary  rights  of  third

IPH6501 issues from such U.S. patent application, it would have a statutory expiration date in 2042, not including patent term adjustment or any
potential patent term extension.

IPH45

As  of  December  31,  2024,  the  principal  intellectual  property  rights  related  to  IPH45  are  solely  owned  by  us,  and  include  one  U.S.  non-
provisional patent application, one European patent application, and other patent applications in certain other countries. If a patent directed to
IPH45 issues from such U.S. patent

111

application, it would have a statutory expiration date in 2043, not including patent term adjustment or any potential patent term extension.

The term of individual patents depends upon the legal term of patents in the countries in which they are obtained. In most countries, including
the United States, the patent term is 20 years from the earliest claimed filing date of a non-provisional patent application or its foreign equivalent
in  the  applicable  country.  In  the  United  States,  a  patent’s  term  may,  in  certain  cases,  be  lengthened  by  patent  term  adjustment,  which
compensates a patentee for administrative delays by the USPTO in examining and granting a patent, or may be shortened if a patent is terminally
disclaimed over a commonly owned patent or a patent naming a common inventor and having an earlier expiration date. In the United States, a
patent  may  also  be  eligible  for  limited  patent  term  extension  under  the  Drug  Price  Competition  and  Patent Term  Restoration Act  of  1984,  or
Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent extension term of up to five years as compensation for patent
term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a total of 14
years from the date of product approval, only one patent applicable to each regulatory review period may be extended and only those claims
covering the approved drug, a method for using it, or a method for manufacturing it may be extended.

Trademarks

The  Company  owns  the  mark  INNATE  PHARMA  in  the  United  States, Australia  and  Europe  (EU  community  trademark),  and  INNATE  in
Europe (EU community trademark). The Company also owns registrations for the mark ANKET  respectively in the United States and Europe
(EU community trademark), and the marks LONKIRLO and KIRTAMSY in the United States, Europe (EU community trademark) and certain
other countries.

Regulation

Research and development work, preclinical tests, clinical studies, facilities, and the manufacture and sale of its products are and will continue to
be subject to the complex legislative and regulatory provisions implemented by the various competent authorities in Europe, the United States
and  other  countries.  The  EMA,  FDA  and  the  various  national  regulatory  authorities  impose  considerable  constraints  on  the  development,
manufacture  and  sale  of  products  that  the  Company  develops  and  clinical  trials  it  conducts.  In  case  of  non-compliance  with  these  laws  or
regulations, the regulatory authorities may impose fines, seize or withdraw products from the market or even partially or totally suspend their
production. They  may  also  revoke  previously  granted  marketing  authorizations  and  reject  applications  seeking  authorization. These  legal  and
regulatory constraints are important in considering whether an investigational product can ultimately become an approved, commercialized drug,
as well as for recognizing the time and investments necessary for such development.

Although  there  are  differences  from  one  country  to  another,  the  development  of  therapeutic  products  for  human  use  is  subject  to  similar
procedures  and  companies  must  comply  with  the  same  types  of  regulations  in  all  ICH  countries  (countries  that  are  part  of  the  International
Council  for  Harmonisation  of  Technical  Requirements  for  Registration  of  Pharmaceuticals  for  Human  Use).  In  order  to  obtain  marketing
authorization  for  a  product,  proof  of  its  efficacy  and  safety  should  be  provided  by  the  applicant,  along  with  detailed  information  on  its
composition and manufacturing process. This entails significant pharmaceutical and preclinical developments, clinical trials and laboratory tests.
The development of a new drug from basic research to commercial marketing generally comprises five steps: (i) research, (ii) preclinical trials,
(iii) clinical trials in humans, (iv) marketing authorization and (v) marketing.

112

Preclinical studies

Preclinical studies include laboratory evaluation of the purity and stability of the manufactured substance or active pharmaceutical ingredient and
the  formulated  product,  as  well  as  in  vitro  and  animal  studies  to  assess  the  safety  and  activity  of  the  product  candidate  for  initial  testing  in
humans and to establish a rationale for therapeutic use. The conduct of preclinical studies is subject to national regulations and requirements,
including Good Laboratory Practices (GLP) regulations. The results of the preclinical tests, together with manufacturing information, analytical
data, any available clinical data or literature and plans for clinical studies, among other things, are submitted to the applicable regulatory agency
in  connection  with  the  application  to  begin  human  testing.  Some  long-term  preclinical  testing,  such  as  animal  tests  of  reproductive  adverse
events and carcinogenicity, and long-term toxicity studies, may continue after submission of the application.

Regulation of clinical trials

In humans, clinical trials are usually carried out in three Phases that are generally sequential, but under certain circumstances Phases of trials can
overlap  or  even  be  skipped,  following  a  specific  review  and  determination  by  regulatory  agencies.  Clinical  trials  are  sometimes  necessary  or
required by regulatory authorities after marketing authorization to explain certain side-effects, investigate a specific pharmacological effect or
obtain more accurate or additional data. Additional trials are also commonly conducted to explore new indications. Regulatory authorization and
ethics approvals are needed to carry out clinical trials. The regulatory authorities may put on clinical hold, block, suspend or require significant
modifications to the clinical study protocols submitted by companies seeking to test products, including the imposition of clinical holds before or
after a clinical trial has commenced.

Clinical trial authorization in the European Union

In the European Union, clinical trials are governed by the Clinical Trials Regulation (EU) No 536/2014 (CTR), which entered into application on
January 31, 2022, repealing and replacing the former Clinical Trials Directive 2001/20 (CTD) and related national implementing legislation of
EU Member States.

The CTR applies to interventional clinical trials on medicinal products and to clinical trials authorized under the CTD with a three-year transition
period from the CTR that has come into operation. As from January 31, 2023, all new clinical trial applications are registered pursuant to the
CTR. Trials approved under the CTD before January 30, 2023 can continue to be regulated under the CTD until January 30, 2025.

The CTR allows better consistency throughout EU Member States:

•

•

Single submission of the clinical trial application dossier through the EU Clinical Trials Information System (Article 5) including a
common part assessed jointly by all participating EU Member States, and a national part covering the ethical and operational aspects
of the trial assessed by each EU Member State independently.

A clinical trial authorization issued in the form of a single decision.

The CTR applies in the Member States without the requirement for separate implementing legislation by each Member State, but some of the
existing laws of the Member States applicable at a national level will continue to apply.

This  regulation  is  intended  to  increase  transparency  of  authorized  clinical  trials  in  the  European  Union:  the  EU  Clinical  Trials  Information
System  serves  as  the  source  of  public  information,  without  prejudice  of  personal  data  protection,  commercially  confidential  information
protection, and protection of confidential communication and trial supervision between Member States. Public information includes

113

clinical trial authorization information, protocol data, and a summary of the results 12 months after the end of the trial (or six months in case of
pediatric clinical trials).

Clinical trial authorization in the United States

In the United States, an Investigational New Drug (IND) application must be submitted to the FDA and accepted before clinical trials can start
on humans. An IND is an exemption from the Federal Food, Drug, and Cosmetic Act (FDCA) that allows an unapproved product candidate to be
shipped in interstate commerce for use in an investigational clinical trial and a request for FDA authorization to administer an investigational
product to humans. This application contains early research data as well as the pharmaceutical dossier, preclinical and clinical data (if any) and
includes the clinical protocol. If there are no objections from the FDA, the IND application becomes valid 30 days after it is received by the
FDA. This waiting period is designed to allow the FDA to review the IND to determine whether human research subjects will be exposed to
unreasonable health risks. At any time during or subsequent to this 30-day period, the FDA may request the suspension or clinical hold of clinical
trials,  whether  such  trials  are  planned  or  in  progress,  and  may  request  additional  information.  This  temporary  suspension  (clinical  hold)
continues until the FDA receives the information it has requested.

In addition to the foregoing IND requirements, one or more independent institutional review board (IRB) covering each institution participating
in the clinical trial must review and approve the plan for any clinical trial before it commences at that institution, and the IRB must conduct
continuing  review  and  reapprove  the  study  at  least  annually.  The  IRB  must  review  and  approve,  among  other  things,  the  study  protocol  and
informed consent information to be provided to study subjects. An IRB must operate in compliance with FDA regulations and other application
regulations and internal compliance procedures. An IRB can suspend or terminate approval of a clinical trial at its institution, or an institution it
represents, if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the product candidate has been associated
with unexpected serious harm to patients.

The  FDA’s  primary  objectives  in  reviewing  an  IND  are  to  assure  the  safety  and  rights  of  patients  and  to  help  assure  that  the  quality  of  the
investigation will be adequate to permit an evaluation of the biological product’s safety, purity and potency. The decision to suspend or terminate
development of an investigational biological product may be made by either a health authority body such as the FDA, an IRB, or by Innate for
various reasons. Additionally, some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a
data  safety  monitoring  board  or  committee  (DSMB).  This  group  provides  authorization  for  whether  or  not  a  trial  may  move  forward  at
designated  check  points  based  on  data  from  the  study  that  is  made  available  to  such  DSMB  for  such  purpose.  Suspension  or  termination  of
development during any Phase of clinical trials can occur if it is determined that the participants or patients are being exposed to an unacceptable
health risk. Other reasons for suspension or termination may be made by Innate based on evolving business objectives and/or the competitive
climate.

Good clinical practices (GCP)

In  most  countries,  clinical  trials  also  must  comply  with  the  current  GCP,  or  cGCP,  standards  as  defined  by  the  International  Council  for
Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH). Directive 2005/28/EC dated April 8, 2005
adopted the cGCP principles in the context of strengthening the regulatory structure specified by Directive 2001/20/EC. In the US, ICH GCP
standards are adopted by FDA as guidance. The competent authority designated in each Member State to authorize clinical trials must take into
consideration, among other factors, the scientific value of the study, the safety of the drug and the possible responsibility of the clinical site.

114

Conducting clinical trials

Clinical trials must be carried out in compliance with complex regulations throughout the various Phases of clinical development, based on the
principle of informed consent by the patient to whom the products will be administered.

Clinical trial Phases

Clinical trials may be conducted in the United States, in Europe or in other parts of the world as long as such trials have been approved by health
authorities  and  ethics  committees  or  IRBs  in  each  country  where  the  trial  is  conducted.  There  are  three  well-established  and  internationally
recognized clinical Phases: Phase 1, 2 and 3. This classification is used by the FDA and the EMA, as well as other regulatory agencies. Each of
these clinical Phases is described below.

•

•

•

Phase 1: The product candidate is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption,
metabolism, distribution and excretion. In the case of some products for severe or life-threatening diseases, such as cancer, especially
when  the  product  may  be  too  inherently  toxic  to  ethically  administer  to  healthy  volunteers,  the  initial  human  testing  is  often
conducted  with  patients.  Sponsors  sometimes  designate  their  Phase  1  trials  as  Phase  1a  or  Phase  1b.  Phase  1b  trials  are  typically
aimed at confirming dosing, pharmacokinetics and safety in larger number of patients. Some Phase 1b studies evaluate biomarkers or
surrogate markers that may be associated with efficacy in patients with specific types of diseases.

Phase  2:  This  Phase  involves  clinical  trials  in  a  limited  patient  population  to  identify  possible  adverse  effects  and  safety  risks,  to
preliminarily  evaluate  the  efficacy  of  the  product  for  specific  targeted  diseases  and  to  determine  dosage  tolerance  and  appropriate
dosage.

Phase 3: Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at
geographically dispersed clinical study sites. These clinical trials, generally comparative, are intended to demonstrate the overall risk-
benefit ratio of the product candidate and provide, if appropriate, an adequate basis for product labeling.

Post-approval trials, sometimes referred to as Phase 4 studies, may be conducted after marketing approval is obtained. These trials are used to
gain additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, the applicable regulator may
mandate the performance of Phase 4 clinical trials as a condition of approval.

In specific situations, certain Phases of development can be merged or even skipped when clear signs of efficacy emerge in the early Phases of
development and the product candidate is designed for patients with major unmet medical needs. However, these deviations from the standard
pattern of development must be discussed and approved by health authorities. Given the high unmet medical need for certain cancer patients,
deviations from the typical Phases of development are frequent in oncology and particularly in the field of immunotherapy.

Disclosure of clinical trial information

Sponsors  of  applicable  clinical  trials  of  FDA-regulated  drugs  are  required  to  register  and  disclose  certain  clinical  trial  information,  which  is
publicly available at www.clinicaltrials.gov. Similarly, in Europe, Sponsors are required to register and disclose certain clinical trial information
on a single portal, CTIS (Clinical Trial Information System), replacing Eudra-CT, set up by the European Medicines Agency (EMA). CTIS is a
single entry point centralizing information and databases on clinical trials in the EU. Eudra-CT will be definitively abandoned at the end of the
transition period, i.e., on January 30, 2025. Information related to the product, patient population, Phase of investigation, study sites and

115

investigators, and other aspects of the clinical trial is then made public as part of the registration. Sponsors of applicable clinical trials are also
obligated to disclose the results of their clinical trials within a certain timeframe after completion. Disclosure of the results of these trials may be
delayed until the new product or new indication being studied has been approved, subject to time-based limitations. Competitors may use this
publicly available information to gain knowledge regarding the progress of development programs.

Regulations concerning marketing authorizations

In order to be marketed, a drug product must have regulatory authorization (known as approval of a New Drug Application (NDA) or licensure
of  a  Biologics  License Application  (BLA)  in  the  United  States,  a  Marketing Authorization Application  (MAA)  in  the  European  Union  and  a
Great  Britain  Marketing Authorisation Application).  The  competent  authorities  are  the  FDA  in  the  United  States,  the  EMA  in  the  European
Union  and  the  Medicines  and  Healthcare  products  Regulatory  Agency  (MHRA)  in  the  United  Kingdom.  Companies  apply  for  a  marketing
authorization based on quality, safety and efficacy data. In the European Union, the United States and Japan, the dossier is a standard dossier
referred  to  as  a  CTD,  or  Common  Technical  Document.  Generally,  the  dossier  describes  the  manufacturing  of  the  drug  substance  (active
substance), the manufacturing of the final product and the clinical and non-clinical studies common to all jurisdictions while providing a separate
module for region-specific information.

United States review and approval process for biological products

In the United States, the FDA licenses complex biological products under the Public Health Service Act, or PHSA. In order to obtain approval to
market a biological product in the United States, a BLA must be submitted to the FDA with data establishing the safety, purity and potency of the
proposed biological product for its intended indication. The application includes all relevant data available from pertinent preclinical and clinical
trials, including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry,
manufacturing, controls and proposed labeling, among other things. Data can come from company-sponsored clinical trials intended to test the
safety and effectiveness of a use of a product, or from a number of alternative sources, including studies initiated by investigators. To support
marketing authorization, the data submitted must be sufficient in quality and quantity to establish the safety, purity and potency of the biological
product to the satisfaction of the FDA.

The BLA is the vehicle through which applicants formally propose that the FDA approve a new biological product for marketing and sale in the
United States for one or more indications. Every new biological product candidate must be the subject of an approved BLA before it may be
commercialized in the United States. Under federal law, the submission of most BLAs is subject to an application user fee and the sponsor of an
approved BLA is also subject to annual program user fees. These fees typically increase annually. Certain exceptions and waivers are available
for some of these fees, such as an exception from the application fee for products with orphan drug designation and a waiver for certain small
businesses, an exception from the establishment fee when the establishment does not engage in manufacturing the product during a particular
fiscal year, and an exception from the product fee for a product that is the same as another product approved under an abbreviated pathway.

Following submission of a BLA, the FDA conducts a preliminary review of the application generally within 60 calendar days of its receipt and
strives to inform the sponsor, via the "Day 74 Letter," by the 74th day after the FDA’s receipt of the submission of whether the application is
sufficiently complete to permit substantive review. The FDA may request additional information rather than accept the application for filing. In
this event, the application must be resubmitted with the additional information. The resubmitted application is also subject to review before the
FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review. The FDA has agreed to
specified

116

performance goals in the BLA review process. Under that agreement, FDA committed to review and act on 90% of applications seeking approval
of original BLA's within 10 months of the filing date and on 90% of original BLA submissions that have been designated for “priority review”
within six months of the filing date. The review process and the Prescription Drug User Fee Act goal date for an original application may be
extended by the FDA for three additional months to consider new information or clarification provided by the applicant to address an outstanding
deficiency identified by the FDA following the original submission.

Before approving an application, the FDA typically will inspect the facility or facilities where the product is or will be manufactured. These pre-
approval  inspections  may  cover  all  facilities  associated  with  a  BLA  submission,  including  component  manufacturing,  finished  product
manufacturing, and control testing laboratories. The FDA will not approve an application unless it determines that the manufacturing processes
and  facilities  are  in  compliance  with  cGMP  requirements  and  adequate  to  assure  consistent  production  of  the  product  within  required
specifications. Additionally, before approving a BLA, the FDA will typically inspect one or more clinical sites to assure compliance with cGCP.

As  a  condition  of  approval,  the  FDA  may  require  an  applicant  to  develop  a  Risk  Evaluation  and  Mitigation  Strategy  (REMS).  REMS  are
required  risk  management  plans  that  use  risk  mitigation  strategies  beyond  the  professional  labeling  to  ensure  that  the  benefits  of  the  product
outweigh the potential risks. To determine whether a REMS is needed, the FDA will consider the size of the population likely to use the product,
seriousness  of  the  disease/condition  to  be  treated,  expected  benefit  of  the  product,  expected  duration  of  treatment,  seriousness  of  known  or
potential adverse events, and whether the product is a new molecular entity.

To support its evaluation, the FDA may request advice from an advisory committee. Preliminary plans on whether to hold an advisory committee
are  included  in  the  Day  74  Letter.  The  FDA  requests  advice  from  advisory  committees  on  a  variety  of  matters,  including  various  aspects  of
clinical  investigations  and  applications  for  marketing  approval  of  drug  products. Advisory  committee  members  are  scientific  experts  such  as
physician-researchers  and  statisticians,  as  well  as  representatives  of  the  public,  including  patients.  The  FDA  is  not  bound  by  the
recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

On  the  basis  of  the  FDA’s  evaluation  of  the  application  and  accompanying  information,  including  the  results  of  the  inspection  of  the
manufacturing facilities, the FDA may issue an approval letter or a complete response letter. An approval letter authorizes commercial marketing
of the product with specific prescribing information for specific indications. A complete response letter generally outlines the deficiencies in the
submission and may require substantial additional testing or information in order for the FDA to reconsider the application. If and when those
deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the BLA, the FDA will issue an approval letter. The FDA has
committed to reviewing and acting on 90% of such resubmissions in two or six months depending on the type of information included. Even
with submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for
approval.

If  the  FDA  approves  a  product,  it  may  limit  the  approved  indications  for  use  for  the  product,  require  that  contraindications,  warnings  or
precautions be included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess
the product’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other
conditions, including distribution restrictions or other risk management mechanisms, including REMS, which can materially affect the potential
market  and  profitability  of  the  product. The  FDA  may  prevent  or  limit  further  marketing  of  a  product  based  on  the  results  of  post-marketing
studies or surveillance programs.

117

Registration procedures in the European Union

To access the European markets through community procedures, drug products must be submitted through the Centralized Procedure, the Mutual
Recognition Procedure or the Decentralized Procedure. The process for doing this depends, among other things, on the nature of the medicinal
product.  Regulation  (EC)  No  726/2004  of  the  European  Parliament  and  of  the  Council  of  March  31,  2004  provides  for  the  Centralized
Procedure.  The  Centralized  Procedure  results  in  a  single  Marketing Authorization  (MA),  granted  by  the  European  Commission  that  is  valid
across the European Economic Area or EEA (i.e., the European Union as well as Iceland, Liechtenstein and Norway). The Centralized Procedure
is compulsory for human drugs that are: (i) derived from biotechnology processes, (ii) contain a new active substance indicated for the treatment
of  certain  diseases,  such  as  cancer,  HIV/AIDS,  diabetes,  neurodegenerative  diseases,  autoimmune  and  other  immune  dysfunctions  and  viral
diseases, (iii) officially designated orphan medicines and (iv) advanced-therapy medicines, such as gene therapy, somatic cell therapy or tissue-
engineered medicines.

Under Article 3 of the Regulation (EC) No 726/2004, the Centralized Procedure is optional for any other human medicinal product if: (1) the
medicinal product contains a new active substance ; or (2) the applicant shows that the medicinal product constitutes a significant therapeutic,
scientific or technical innovation or that the granting of authorization in accordance with this Regulation is in the interests of patients health at
the EU level.

Under the Centralized Procedure in the European Union, the European Medicines Agency (EMA), shall ensure that the opinion of the Committee
for  Medicinal  Products  for  Human  Use  (CHMP),  is  given  within  210  days  (Article  6.3).  This  excludes  so-called  clock  stops,  during  which
additional written or oral information is to be provided by the applicant in response to questions asked by the CHMP (Article 7). At the end of
the review period, the CHMP provides its opinion through a scientific assessment report to the European Commission. The Commission may
then adopt a final decision to grant an MA. Once granted, the MA is valid across all EEA countries for an initial period of five years. Since 2008,
as  a  consequence  of  a  European  directive,  a  marketing  authorization  is  now  renewed  only  once,  five  years  after  the  initial  registration.  The
marketing  authorization  shall  be  then  valid  for  an  unlimited  period,  unless  the  Commission  decides,  on  justified  grounds,  relating  to
pharmacovigilance, to proceed with one additional five-year renewal.

National  MAs,  issued  by  the  competent  authorities  of  the  member  states  of  the  EEA,  are  also  available;  however  these  only  cover  their
respective  territory.  National  MAs  may  be  applied  for  through  the  Mutual  Recognition  Procedure  or  Decentralized  Procedure  in  order  that
multiple competent authorities in different member states of the EEA may each issue a national MA in their territory for the same product on the
back of the same application. National MAs are only available for products not falling within the mandatory scope of the Centralized Procedure.

It is possible for a drug to be withdrawn from the market, upon the request of the health authorities, if a serious problem arises, in particular a
safety-related problem. The marketing authorization is then cancelled. There can be various reasons for the withdrawal of drugs from the market,
with the main reasons being public health, major undesirable side effects and non-compliance with manufacturing rules.

Non-standard regulatory procedures

Aside  from  the  standard  procedures  of  granting  a  BLA  or  a  European  MA,  as  described  above,  non-standard  regulatory  procedures  allow  a
shorter time-to-market for new medicines.

118

The following programs that are in place in the United States are intended to facilitate the development and/or expedite the review and potential
approval of drug products:

•

•

•

•

Accelerated Approval: FDA may grant accelerated approval to a product for a serious or life-threatening disease or condition upon a
determination that the product has an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, or on a clinical
endpoint  that  can  be  measured  earlier  than  irreversible  morbidity  or  mortality,  that  is  reasonably  likely  to  predict  an  effect  on
irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity, or prevalence of the condition and
the  availability  or  lack  of  alternative  treatments.  This  procedure  is  somewhat  comparable  to  the  “conditional  approval”  in  the
European Union.

Priority Review: An application for a drug will receive priority review designation if it is for a drug that treats a serious condition and,
if approved, would provide a significant improvement in safety or effectiveness. Priority Review provides for a shorter review clock:
the time it takes FDA to review a filed BLA is reduced to six months rather than 10 months. This procedure is somewhat comparable
to the “accelerated assessment” in the European Union.

The  Fast  Track  Designation:  Section  506(b)  of  the  FDCA  provides  for  the  designation  of  a  drug  as  a  fast  track  product  “if  it  is
intended, whether alone or in combination with one or more other drugs, for the treatment of a serious or life-threatening disease or
condition,  and  it  demonstrates  the  potential  to  address  unmet  medical  needs  for  such  a  disease  or  condition.”  This  provision  is
intended to facilitate development and expedite review of drugs to treat serious and life-threatening conditions so that an approved
product can reach the market expeditiously. For fast track designated drugs, sponsors may have a higher number of interactions with
the FDA. In addition, the FDA may review sections of the BLA for a fast track designated drug on a rolling basis before the complete
application is submitted. Fast track designation may be rescinded if the qualifying criteria are no longer met. Fast Track designation
does not necessarily lead to a Priority Review or Accelerated Approval.

The Breakthrough Therapy Designation: Section 506(a) of the FDCA provides for designation of a drug as a breakthrough therapy “if
the drug is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition
and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or
more clinically significant endpoints, such as substantial treatment effects observed early in clinical development.” The standard for
breakthrough  therapy  designation  is  not  the  same  as  the  standard  for  drug  approval  as  the  clinical  evidence  needed  to  support
breakthrough designation is preliminary. In contrast, as is the case for all drugs, FDA will review the full data submitted to support
approval of drugs designated as breakthrough therapies to determine whether the drugs are safe and effective for their intended use
before they are approved for marketing. The program provides the same advantages of the fast track designation, but also includes
intensive FDA guidance to promote efficient development and FDA organizational commitment. Breakthrough therapy designation
may be rescinded if the qualifying criteria are no longer met.

In the European Union, non-standard registration procedures under the Centralized Procedures are as follows:

•

Conditional  marketing  authorization:  valid  one  year  (instead  of  five).  It  is  granted  only  if  the  benefit  /  risk  ratio  is  positive,  if  the
product addresses unmet medical needs, and if the benefits to public health outweigh the risks associated with uncertainty because of
an incomplete evaluation of the drug (for instance, because of clinical trials still ongoing at the time of the

119

•

•

•

evaluation, or when additional clinical trials are needed). It is renewed annually if an appropriate report is submitted annually by the
sponsor. Once the results of the pending studies are provided, it can become a “regular” marketing authorization.

Approval  under  exceptional  circumstances:  a  marketing  authorization  may  be  granted  in  exceptional  cases,  reviewed  each  year  to
reassess the risk-benefit balance when the initial dossier for assessment of the drug cannot contain all required data, for instance when
the condition to be treated is rarely encountered.

Accelerated assessment : the evaluation process is accelerated (150 days instead of 210 days) when a drug is of major interest from
the standpoint of public health or in particular from the viewpoint of therapeutic innovation.

The PRIME (priority medicines) scheme refers to a process for enhanced interactions and early dialogue with EMA to facilitate the
development  and  speed  up  examination  of  drugs  which  target  unmet  medical  needs  or  offer  a  major  therapeutic  advantage  over
existing treatments. Through PRIME, drug developers can expect to be eligible for accelerated assessment at the time of application
for a marketing authorization.

As part of the EU pharmaceuticals strategy, the EU Commission worked on a revision of the EU’s general legislation on medicines for human
use. On April 26, 2023 the EU Commission adopted a Directive proposal and a Regulation proposal, which represent the largest pharmaceutical
reform in over 20 years. The revision will impact the global legal framework for medicinal products in the EU, including legislation relating to
orphan and pediatric drugs and will review the incentives system (data protection and market exclusivity) in place (see also below “—European
Union proposed revision of the general pharmaceutical legislation”).

Orphan drugs

Generally, orphan drugs are drugs used for the prevention or treatment of life-threatening or serious rare conditions.

In the United States, the 1983 Orphan Drug Act was passed to encourage the development of drugs for rare disease or conditions. In the United
States, a rare disease or condition is defined as a disease that affects fewer than 200,000 people in the United States, or affects more than 200,000
but there is no reasonable expectation that the cost of developing and making available a drug for such disease or condition in the United States
will be recovered from U.S. sales of the drug. The FDA has authority to grant orphan drug designation to a drug or biological product to prevent,
diagnose or treat a rare disease or condition, a designation which carries with it the following incentives: the possibility of obtaining research
grants from the American government for clinical trials; tax credits for a portion of research costs; a possible exemption from user fees; and the
potential for a seven-year period of exclusivity if a marketing authorization is granted.

Regarding orphan drug exclusivity, if a product with orphan drug designation receives the first FDA approval for the disease or condition for
which it has such designation or for a select indication or use within the rare disease or condition for which it was designated, the product will
generally  receive  orphan  drug  exclusivity.  Orphan  drug  exclusivity  means  that  the  FDA  may  not  approve  another  sponsor’s  marketing
application for the same drug for the same use or indication for seven years, except in certain limited circumstances. Orphan drug exclusivity
does not block the approval of a different product for the same rare disease or condition, nor does it block the approval of the same product for
different indications. If a product designated as an orphan drug ultimately receives marketing approval for an indication broader than what was
designated in its orphan drug application, it may not be entitled to exclusivity.

120

Orphan  exclusivity  will  not  bar  approval  of  another  product  under  certain  circumstances,  including  if  a  subsequent  product  that  is  the  same
biologic for the same use or indication is shown to be clinically superior to the approved product on the basis of greater effectiveness than the
approved  drug,  greater  safety  in  a  substantial  portion  of  the  target  populations,  or  demonstration  of  a  major  contribution  to  patient  care.
Additionally,  FDA  may  approve  another  application  for  the  same  biologic  for  the  same  use  or  condition  notwithstanding  the  applicability  of
orphan drug exclusivity, if the company with orphan drug exclusivity is not able to assure a sufficient quantity of the drug.

In the European Union, equivalent legislation has been adopted to promote treatments for rare diseases (Regulation 141/2000/EC of December
16, 1999, as amended by Regulation 847/2000/EC of April 27, 2000). A medicinal product may be designated as orphan if: (a) it is intended for
the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition affecting not more than five in 10,000 persons in
the European Union when the application is made, or (b) it is intended for the diagnosis, prevention or treatment of a life-threatening, seriously
debilitating or serious and chronic condition in the European Union and that without incentives it is unlikely that the marketing of the medicinal
product in the European Union would generate sufficient return to justify the necessary investment.

For either of these conditions, the applicant must demonstrate that there exists no satisfactory method of diagnosis, prevention or treatment of the
condition in question that has been authorized in the EU or, if such method exists, the medicinal product will be of significant benefit to those
affected by that condition.

Medicinal products receiving orphan designation in the European Union can receive 10 years of market exclusivity, during which time no similar
medicinal product can be submitted for the same therapeutic indication. An orphan product can also obtain an additional two years of market
exclusivity in the European Union for pediatric studies (in this case for orphan drugs no extension to any supplementary protection certificate
can be granted, see further detail below). Orphan medicinal products are also eligible for financial incentives such as reduction of fees or fee
waivers  and  scientific  assistance  for  study  proposals.  (Articles  6  and  9  of  the  above-mentioned  regulation).  The  application  for  orphan  drug
designation must be submitted before the application for marketing authorization (Article 5). The applicant will receive a fee reduction for the
marketing authorization application if the orphan drug designation has been granted, but not if the designation is still pending at the time the
marketing  authorization  is  submitted.  Orphan  drug  designation  does  not  convey  any  advantage  in,  or  shorten  the  duration  of,  the  regulatory
review and approval process.

The 10-year market exclusivity may be reduced to six years if, at the end of the fifth year, it is established that the product no longer meets the
criteria for orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of market exclusivity (Article 8).
However, marketing authorization may be granted to a similar medicinal product for the same indication at any time if:

•

•

•

the  holder  of  the  marketing  authorization,  or  MA,  for  the  original  orphan  medicinal  product  has  given  its  consent  to  the  second
applicant;

the holder of the MA for the original orphan medicinal product cannot supply sufficient quantities of the orphan medicinal product; or

the  second  applicant  can  establish  in  the  application  that  its  product,  although  similar  to  the  orphan  medicinal  product  already
authorized, is safer, more effective or otherwise clinically superior.

European Union proposed revision of the general pharmaceutical legislation

The European Union is currently contemplating a major revision of the general pharmaceutical legislation. The revision is still under tripartite
discussions between the European Commission, the

121

European  Parliament  and  the  European  Council  of  Member  States,  and  adoption  is  unlikely  until  2028. The  most  concerning  draft  proposals
relate to modulated regulatory data protection and orphan market exclusivity periods; greater transparency in R&D costs; faster availability of
generics and biosimilars; and more stringent obligations for the supply of medicines.

Separately, harmonization of EU health technology assessment (HTA) is intended to improve patient access inequalities in Europe, with official
implementation in January 2025. To achieve this, a joint EU HTA process is being implemented in phases, starting with oncology medicines and
advanced therapy medicinal products (ATMPs) from 2025, before expanding to orphan drugs in 2028 and other products in 2030.

It will introduce EU-level joint scientific consultations (JSCs) and joint clinical assessments (JCAs) that will serve as the basis for national value
assessments and price negotiations. 25 JCAs are planned to be conducted by the EU HTA Coordination Group (HTACG) in 2025.

While preparations gathered pace in 2024, there are short-term risks and uncertainties related to the new JCA framework, especially as regards
methodologies (i.e. comparators and endpoints), potential delayed assessments, and the disruption caused to national HTA processes in adopting
EU HTA without additional resources.

In addition, the new EU HTA regulation will trigger increased workload and higher evidence requirements at launch, requiring manufacturers to
adapt their operating models. As countries and companies transition to the new processes, EU-wide coordination on HTA is anticipated to gain
momentum, albeit slower than initially expected.

Another  priority  of  the  European  Commission  is  to  secure  the  uninterrupted  supply  of  medicines  in  Europe.  In  2024  it  launched  the  Critical
Medicines Alliance, paving the way for a possible Critical Medicines Act in the future. To mitigate drug shortages, the European Commission is
pursuing  several  actions  including  reshoring  of  generics  production,  compulsory  stockpiling,  and  joint  procurement  of  the  most  critical
medicines.

Registration procedures outside of the European Union and the United States

In addition to regulation in the United States and the European Union, a variety of foreign regulations govern clinical trials, commercial sales
and  distribution  of  drugs.  Pharmaceutical  firms  who  wish  to  market  their  medicinal  drugs  outside  the  European  Union  and  the  United  States
must submit marketing authorization application to the national authorities of the concerned countries, such as the Pharmaceutical and Medical
Device Agency (PMDA) in Japan. The approval process varies from jurisdiction to jurisdiction and the time to approval may be longer or shorter
than that required by the FDA or European Commission.

Of note, in the United Kingdom (which comprises Great Britain and Northern Ireland), Great Britain is no longer covered by EU centralized
procedures for MAs (under the Northern Ireland Protocol, EU centralized procedures for MAs continue to be recognized in Northern Ireland).
For a period of two years from January 1, 2021, when determining an application for a Great Britain Marketing Authorization, the MHRA was
allowed to rely on on a decision taken by the European Commission on the approval of a new MA in the centralized procedure (the European
Decision Reliance Procedure). On January 1, 2024, a new international recognition framework procedure (IRP) replaced the European Decision
Reliance Procedure. Under the IRP, the MHRA may take into account the approval of MAs made by the EMA and certain other regulators. The
MHRA also has the power to take into account MAs approved in EU Member States through decentralized or mutual recognition procedures
with a view to more quickly granting an MA in the United Kingdom.

122

Post-approval regulations

Post-approval regulation in the United States

Biologics  manufactured  or  distributed  pursuant  to  FDA  licensure  are  subject  to  pervasive  and  continuing  regulation  by  the  FDA,  including,
among  other  things,  requirements  relating  to  recordkeeping,  periodic  reporting,  product  sampling  and  distribution,  advertising  and  promotion
and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications or
other labeling claims, are subject to prior FDA review and approval. There are also continuing, annual user fee requirements for any marketed
products and the establishments at which such products are manufactured, as well as new application fees for supplemental applications with
clinical data.

In  addition,  manufacturers  and  other  entities  involved  in  the  manufacture  and  distribution  of  approved  products  are  required  to  register  their
establishments  with  the  FDA  and  state  agencies,  and  are  subject  to  periodic  unannounced  inspections  by  the  FDA  and  aforementioned  state
agencies  for  compliance  with  drug  manufacturing  regulations,  including  current  good  manufacturing  practices  (cGMP).  Changes  to  the
manufacturing  process  are  strictly  regulated  and  often  require  prior  FDA  approval  before  being  implemented.  FDA  regulations  also  require
investigation  and  correction  of  any  deviations  from  cGMP  and  impose  reporting  and  documentation  requirements  upon  the  sponsor  and  any
third-party manufacturers that the sponsor may decide to use.

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or
if  problems  occur  after  the  product  reaches  the  market.  Later  discovery  of  previously  unknown  problems  with  a  product,  including  adverse
events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in
revising  the  approved  labeling  to  add  new  safety  information;  imposing  post-market  studies  or  clinical  trials  to  assess  new  safety  risks;  or
imposing distribution or other restrictions under a REMS program. Other potential consequences include, among other things:

•

•

•

•

•

restrictions  on  the  marketing  or  manufacturing  of  the  product,  suspension  of  the  approval,  or  complete  withdrawal  of  the  product
from the market or product recalls;

fines, warning letters or holds on post-approval clinical trials;

refusal of the FDA to approve pending applications or supplements to approved BLAs, or suspension or revocation of product license
approvals;

product seizure or detention, or refusal to permit the import or export of products; and

injunctions or the imposition of civil or criminal penalties.

In  addition,  the  distribution  of  prescription  pharmaceutical  products  is  subject  to  the  Prescription  Drug  Marketing  Act  (PDMA)  and  its
implementing regulations, as well as the Drug Supply Chain Security Act (DSCSA), which respectively regulate the distribution and tracing of
prescription drug samples at the federal level and set floor and ceiling standards for the regulation of wholesale distributors by the states. PDMA,
its  implementing  regulations  and  state  laws  limit  the  distribution  of  prescription  pharmaceutical  product  samples,  and  DSCSA  imposes
requirements to ensure accountability during distribution and to identify and remove counterfeit and other illegitimate products from the market,
each among other objectives.

The  FDA  strictly  regulates  labels/labeling,  advertising  and  promotion  of  prescription  drugs  that  are  placed  on  the  market. The  FDA-required
labeling  sets  forth  the  conditions  of  use  under  which  the  licensed  biologics  has  been  shown  to  meet  the  relevant  standard  for  marketing  and
provides directions and information on how to use the product safely and effectively under those conditions. Licensed biologics

123

may be promoted only for the approved indications and in accordance with the provisions of the approved label, including information consistent
with the FDA required labeling and not otherwise false or misleading. The FDA and other agencies actively enforce the laws and regulations
prohibiting the promotion of off-label uses. A company that is found to have improperly promoted off-label uses may be subject to significant
liability.

Patent term restoration and extension in the United States

A patent claiming a new biologic product may be eligible for a limited patent term extension under the Hatch-Waxman Act, which permits a
patent restoration of up to five years for patent term lost during product development and the FDA regulatory review period. A regulatory review
period consists of two periods of time: a testing phase and an approval phase. The restoration period granted on a patent covering a product is
calculated  as  one-half  the  testing  phase  (the  time  between  the  exemption  to  permit  the  clinical  investigations  of  the  drug  product  becomes
effective  and  start  of  the  approval  phase)  plus  the  approval  phase  (the  time  between  the  submission  date  of  an  application  and  the  ultimate
approval date). A maximum of five years can be restored to a patent and patent term extension cannot be used to extend the remaining term of a
patent past a total of 14 years from the product’s approval date. Additionally, only one patent applicable to an approved product is eligible for the
extension, the application for the extension must be submitted prior to the expiration of the patent in question, and only those claims covering the
approved  drug,  a  method  for  using  it,  or  a  method  for  manufacturing  it  may  be  extended. A  patent  that  covers  multiple  products  for  which
approval  is  sought  can  only  be  extended  in  connection  with  one  of  the  approvals. The  USPTO  reviews  and  approves  the  application  for  any
patent term extension or restoration in consultation with the FDA. For more information regarding the risks related to patent term restoration and
extension, please see “Risk Factors—Risks Related to Intellectual Property Rights—If the Company does not obtain protection under the Hatch-
Waxman Amendments and similar non-U.S. legislation for extending the term of patents covering Lumoxiti and each of its product candidates,
its business may be materially harmed.”

Healthcare law and regulation in the United States

Healthcare providers and third-party payors play a primary role in the recommendation and prescription of biologic products that are granted
marketing  approval. Arrangements  with  providers,  consultants,  third-party  payors  and  customers  are  subject  to  broadly  applicable  fraud  and
abuse,  anti-kickback,  false  claims  laws,  transparency  laws  and  patient  data  privacy  laws,  and  regulations  and  other  healthcare  laws  and
regulations  that  may  constrain  business  and/or  financial  arrangements.  Restrictions  under  applicable  federal  and  state  healthcare  laws  and
regulations, include the following:

•

•

•

the U.S. Anti-Kickback Statute, which prohibits, among other things, persons and entities from knowingly and willfully soliciting,
offering, paying, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral
of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made, in whole or
in part, under a federal healthcare program such as Medicare and Medicaid;

the U.S. civil and criminal false claims laws, including the civil False Claims Act, and civil monetary penalties laws, which prohibit
individuals or entities from, among other things, knowingly presenting, or causing to be presented, to the federal government, claims
for  payment  that  are  false,  fictitious  or  fraudulent  or  knowingly  making,  using  or  causing  to  be  made  or  used  a  false  record  or
statement to avoid, decrease or conceal an obligation to pay money to the federal government;

the U.S. Health Insurance Portability and Accountability Act of 1996 (HIPAA), which created additional federal criminal laws that
prohibit, among other things, knowingly and willfully

124

executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit  program  or  making  false  statements  relating  to
healthcare matters;

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, and their respective implementing
regulations,  including  the  Final  Omnibus  Rule  published  in  January  2013,  which  impose  obligations  on  covered  entities  and  their
business  associates,  including  mandatory  contractual  terms,  with  respect  to  safeguarding  the  privacy,  security  and  transmission  of
individually identifiable health information;

the  federal  transparency  requirements  known  as  the  federal  Physician  Payments  Sunshine  Act,  under  the  Patient  Protection  and
Affordable Care Act, as amended by the Health Care Education Reconciliation Act, or the ACA, which requires certain manufacturers
of drugs, devices, biologics and medical supplies to report annually to the Centers for Medicare & Medicaid Services (CMS) within
the United States Department of Health and Human Services, information related to payments and other transfers of value made by
that entity to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate
family members; and

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to healthcare
items or services that are reimbursed by non-governmental third-party payors, including private insurers.

•

•

•

Some  state  laws  require  pharmaceutical  companies  to  comply  with  the  pharmaceutical  industry’s  voluntary  compliance  guidelines  and  the
relevant  compliance  guidance  promulgated  by  the  federal  government  in  addition  to  requiring  manufacturers  to  report  information  related  to
payments to physicians and other health care providers or marketing expenditures. Certain state laws require the reporting of information relating
to  drug  and  biologic  pricing;  and  some  state  and  local  laws  require  the  registration  of  pharmaceutical  sales  representatives.  State  and  foreign
laws also govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways
and often are not preempted by HIPAA, thus complicating compliance efforts.

Failure to comply with these laws or any other governmental regulations as applicable, could result in the imposition of significant civil, criminal
and  administrative  penalties,  damages,  fines,  disgorgement,  imprisonment,  possible  exclusion  from  government  funded  healthcare  programs,
such as Medicare and Medicaid, additional integrity reporting requirements and oversight, as well as contractual damages, reputational harm,
diminished profits and future earnings, and curtailment of operations.

Healthcare reform in the United States

A  primary  trend  in  the  United  States  healthcare  industry  and  elsewhere  is  cost  containment.  There  have  been  a  number  of  federal  and  state
proposals and changes during the last few years regarding the pricing of pharmaceutical and biopharmaceutical products, limiting coverage and
reimbursement for biologics and other medical products, government control and other changes to the healthcare system in the United States.

On March 23, 2010, President Obama signed into law the ACA, which includes a number of healthcare reform provisions. The ACA, among
other things, imposed a significant annual fee on companies that manufacture or import branded prescription drug products; addressed a new
methodology  by  which  rebates  owed  by  manufacturers  under  the  Medicaid  Drug  Rebate  Program  are  calculated  for  drugs  that  are  inhaled,
infused,  instilled,  implanted  or  injected;  increased  the  minimum  Medicaid  rebates  owed  by  manufacturers  under  the  Medicaid  Drug  Rebate
Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations; and established a new Medicare Part
D coverage gap discount program, in which manufacturers were required to agree to offer 50% point-of-sale discounts off

125

negotiated  prices  of  applicable  brand  drugs  to  eligible  beneficiaries  during  their  coverage  gap  period,  as  a  condition  for  the  manufacturer’s
outpatient drugs to be covered under Medicare Part D. Substantial new provisions affecting compliance also were added. The ACA also revised
the definition of “average manufacturer price” for reporting purposes, which could increase the amount of Medicaid drug rebates to states.

Most judicial, congressional, and executive branch efforts to repeal, modify or delay the implementation of the law have been unsuccessful, and
the law remains in effect.

In addition, other legislative changes have been proposed and adopted in the United States since the ACA was enacted. For example, in August
2011, the Budget Control Act of 2011, among other things, included aggregate reductions to Medicare payments to providers and suppliers of
2%  per  fiscal  year,  starting  in  2013,  and,  due  to  subsequent  legislative  amendments  to  the  statute,  will  remain  in  effect  through  2032,  unless
additional Congressional action is taken.

Furthermore,  there  has  been  increasing  legislative  and  enforcement  interest  in  the  United  States  with  respect  to  drug  pricing  practices. There
have been several recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things,
bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the cost of drugs
under Medicare, and reform government program reimbursement methodologies for drugs.

For example, in August 2022, the Inflation Reduction Act of 2022 was signed into law. This legislation contains substantial drug pricing reforms,
including the establishment of a drug price negotiation program within the U.S. Department of Health and Human Services that would require
manufacturers  to  charge  a  negotiated  “maximum  fair  price”  for  certain  selected  drugs  or  pay  an  excise  tax  for  noncompliance. The  IRA  also
imposes penalties on drug manufacturers in the form of mandatory additional rebates and/or discounts if commercial prices increase at a rate
greater than the U.S. Bureau of Labor Statistics consumer price index, and these rebates or discounts, which can be substantial, may affect the
Company's ability to raise commercial prices. The Inflation Reduction Act of 2022 also caps Medicare beneficiaries’ annual out-of-pocket drug
expenses. Provisions of the IRA are subject to legal challenges, and the full impact of the IRA on the pharmaceutical industry remains uncertain.

However,  recent  election  results  in  the  U.S.  may  spark  uncertainty  for  the  IRA. Although  a  full  repeal  of  the  IRA  may  be  unlikely  due  to
budgetary  impact,  the  new  U.S.  administration  could  change  some  of  the  IRA  provisions,  including  Medicare  drug  price  negotiations.
Additionally,  under  the  current  U.S.  administration,  the  FDA  is  facing  staff  reductions,  which  could  impact  the  FDA’s  ability  to  engage  in
regulatory and oversight activities and could result in delays or limitations on Innate’s ability to proceed with clinical development programs and
obtain regulatory approvals. It is difficult to predict how executive actions that may be taken under the current U.S. administration may affect the
FDA’s ability to exercise its regulatory authority, which could negatively impact our business.

At the state level, legislatures are increasingly passing legislation and implementing regulations designed to control pharmaceutical and
biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing
cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing.

Pharmacovigilance system in the European Union

An  MA  holder  in  the  EU  must  establish  and  maintain  a  pharmacovigilance  system  and  appoint  an  individual  qualified  person  for
pharmacovigilance (QPPV), who is responsible for oversight of the

126

pharmacovigilance system. Key obligations include expedited reporting of suspected serious adverse reactions and submission of periodic safety
update reports (PSURs).

All new MA applications must include a risk management plan (RMP) describing the risk management system that the company will put in place
and  documenting  measures  to  prevent  or  minimize  the  risks  associated  with  the  product. The  regulatory  authorities  may  also  impose  specific
obligations  as  a  condition  of  the  MA.  Such  risk-minimization  measures  or  post-authorization  obligations  may  include  additional  safety
monitoring,  more  frequent  submission  of  PSURs  or  the  conduct  of  additional  clinical  trials  or  post-authorization  safety  studies.  RMPs  and
PSURs are routinely available to third parties requesting access, subject to limited redactions.

Advertising regulation in the European Union

All advertising and promotional activities for the product must be consistent with the approved summary of product characteristics, and therefore
all  off-label  promotion  is  prohibited.  Direct-to-consumer  advertising  of  prescription  medicines  is  also  prohibited  in  the  European  Union.
Although general requirements for advertising and promotion of medicinal products are established under European Union directives, the details
are governed by regulations in each European Union Member State and can differ from one country to another.

If the Company fails to comply with applicable foreign regulatory requirements, the Company may be subject to fines, suspension or withdrawal
of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Pharmaceutical coverage, pricing and reimbursement

European Union

In the European Union, pricing and reimbursement schemes vary widely from country to country. In some countries, products may be marketed
only  after  a  reimbursement  price  has  been  agreed.  Some  countries  may  require  the  completion  of  additional  studies  that  compare  the  cost-
effectiveness  of  a  particular  product  candidate  to  currently  available  therapies  or  so-called  health  technology  assessments,  in  order  to  obtain
reimbursement or pricing approval. For example, the European Union provides options for its member states to restrict the range of products for
which  their  national  health  insurance  systems  provide  reimbursement  for  and  to  control  the  prices  of  medicinal  products  for  human  use.
European Union member states may approve a specific price for a product or it may instead adopt a system of direct or indirect controls on the
profitability of the company placing the product on the market. Other member states allow companies to fix their own prices for products, but
monitor  and  control  prescription  volumes  and  issue  guidance  to  physicians  to  limit  prescriptions.  Recently,  many  countries  in  the  European
Union  have  increased  the  amount  of  discounts  required  on  pharmaceuticals  and  these  efforts  could  continue  as  countries  attempt  to  manage
healthcare  expenditures,  especially  in  light  of  the  severe  fiscal  and  debt  crises  experienced  by  many  countries  in  the  European  Union.  The
downward pressure on health care costs in general, particularly prescription products, has become intense. As a result, increasingly high barriers
are being erected to the entry of new products. Political, economic and regulatory developments may further complicate pricing negotiations, and
pricing negotiations may continue after reimbursement has been obtained. Reference pricing used by various European Union member states,
and parallel trade, i.e., arbitrage between low-priced and high-priced member states, can further reduce prices. There can be no assurance that
any  country  that  has  price  controls  or  reimbursement  limitations  for  pharmaceutical  products  will  allow  favorable  reimbursement  and  pricing
arrangements for any products, if approved in those countries.

127

United States

In the United States, patients who have treatments prescribed for their conditions and providers performing the prescribed services generally rely
on  third-party  payors  to  reimburse  all  or  part  of  the  associated  healthcare  costs.  Significant  uncertainty  exists  as  to  the  coverage  and
reimbursement status of products approved by the FDA. Thus, even if a product candidate is approved, sales of the product will depend, in part,
on  the  extent  to  which  third-party  payors,  including  government  health  programs  in  the  United  States  such  as  Medicare  and  Medicaid,
commercial health insurers and managed care organizations, provide coverage, and establish adequate reimbursement levels for, the product. The
process  for  determining  whether  a  payor  will  provide  coverage  for  a  product  may  be  separate  from  the  process  for  setting  the  price  or
reimbursement rate that the payor will pay for the product once coverage is approved. Third-party payors are increasingly challenging the prices
charged,  examining  the  medical  necessity,  and  reviewing  the  cost-effectiveness  of  medical  products  and  services  and  imposing  controls  to
manage costs. Third-party payors may limit coverage to specific products on an approved list, also known as a formulary, which may not include
all of the approved products for a particular indication.

In  order  to  secure  coverage  and  reimbursement  for  any  product  that  might  be  approved  for  sale,  a  company  may  need  to  conduct  expensive
pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required
to obtain FDA or other comparable marketing approvals. Nonetheless, product candidates may not be considered medically necessary or cost
effective. A decision by a third-party payor not to cover a product candidate could reduce physician utilization once the product is approved,
which  could  have  a  material  adverse  effect  on  sales,  results  of  operations  and  financial  condition. Additionally,  a  payor’s  decision  to  provide
coverage  for  a  product  does  not  imply  that  an  adequate  reimbursement  rate  will  be  approved.  Further,  one  payor’s  determination  to  provide
coverage for a product does not assure that other payors will also provide coverage and reimbursement for the product, and the level of coverage
and reimbursement can differ significantly from payor to payor.

The containment of healthcare costs also has become a priority of federal, state and foreign governments and the prices of products have been a
focus  in  this  effort.  Governments  have  shown  significant  interest  in  implementing  cost-containment  programs,  including  price  controls,
restrictions on reimbursement and requirements for substitution of generic products. Adoption of price controls and cost-containment measures,
and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit a company’s revenue generated
from  the  sale  of  any  approved  products.  Coverage  policies  and  third-party  reimbursement  rates  may  change  at  any  time.  Even  if  favorable
coverage and reimbursement status is attained for one or more products for which a company or its collaborators receive marketing approval,
less favorable coverage policies and reimbursement rates may be implemented in the future.

Anti-corruption, anti-kickback and transparency regulations

Arrangements  with  healthcare  providers,  physicians,  third-party  payors  and  customers  can  expose  pharmaceutical  manufactures  to  broadly
applicable anti-bribery, fraud and abuse and other healthcare laws and regulations, which may constrain the business or financial arrangements
and relationships through which such companies sell, market and distribute pharmaceutical products.

More  specifically,  each  of  the  above-mentioned  steps  of  the  development  of  therapeutic  products  for  human  use  is  heavily  regulated  and
therefore  involves  significant  interaction  with  public  officials  which  is  likely  to  cause  a  risk  of  corruption  or  bribery.  For  instance,  in  many
countries, hospitals are operated by the government, and doctors and other hospital employees are considered foreign officials. Certain payments
to hospitals in connection with clinical trials and other work have been deemed to be improper payments to government officials and have led to
enforcement actions. That is why business activity may

128

be  subject  to  anti-bribery  or  anti-corruption  laws,  regulations  or  rules  of  other  countries  in  which  the  Company  operates,  including  without
limitation the Foreign Corrupt Practices Act, the U.K. Bribery Act or the French Sapin 2 Law.

These statutes generally prohibit offering, promising, giving, or authorizing others to give anything of value, either directly or indirectly, to a
government or a foreign government official or employees of public international organizations in order to influence official action, or otherwise
obtain  or  retain  business. The  implementation  of  these  statutes  may  also  impose  internal  compliance  programs,  procedures  and  guidelines  to
detect and report any suspicious activities and to mitigate any risks of noncompliance which may occur.

In addition, the Company may be subject to specific healthcare regulations, including, without limitation:

•

•

the  French  “transparency”  provisions,  or  “French  Sunshine Act”  (Articles  L.  1453-1  and  D.  1453-1  and  seq.  of  the  French  Public
Health  Code  or  PHC),  which  contains  provisions  regarding  transparency  of  fees  received  by  some  healthcare  professionals  from
industries,  i.e.  companies  manufacturing  or  marketing  healthcare  products  (medicinal  products,  medical  devices,  etc.)  in  France.
these  companies  shall  publicly  disclose  (on  a  specific  public  website  available  at
According 
https://transparence.sante.gouv.fr) the advantages and fees paid to healthcare professionals amounting to €10 or above, as well as the
agreements  concluded  with  the  latter,  along  with  detailed  information  about  each  agreement  (the  precise  subject  matter  of  the
agreement, the date of signature of the agreement, its end date, the total amount paid to the healthcare professional, etc.); and

the  provisions, 

to 

the French “anti-gift” provisions (Articles L.1453-3 to L.1453-12 PHC), setting out a general prohibition of payments and rewards
from  industries,  i.e.  companies  manufacturing  or  marketing  health  products  to  healthcare  professionals  (HCP),  healthcare
organizations (HCO), healthcare associations and students with limited exceptions, and strictly defining the conditions under which
such  payments  or  awards  are  lawful.  The  regime  entails  strict  formalities  depending  on  the  amount  paid,  when  authorized,  to  the
HCP, HCO, students or associations.

Data protection rules

The Regulation 2016/679, known as the General Data Protection Regulation, or GDPR, that came into force on May 25, 2018, as well as EU
Member  State  implementing  legislations,  apply  to  the  collection  and  processing  of  personal  data,  including  health-related  information,  by
companies  located  in  the  EU,  or  in  certain  circumstances,  by  companies  located  outside  of  the  EU  and  processing  personal  information  of
individuals located in the EU.

These laws impose strict obligations on the ability to process personal data, including health-related information, in particular in relation to their
collection, use, disclosure and transfer.

Also, in certain countries, in particular France, the conduct of clinical trials is subject to compliance with specific provisions of the Act No.78-17
of January 6, 1978 on Information Technology, Data Files and Civil Liberties, as amended. These provisions require, among others, the filing of
compliance undertakings with “standard methodologies” and a specific framework applicable to the retention of personal data when researching
in  the  health  sector  (July  2020)  adopted  by  the  French  Data  Protection  Authority  (the  CNIL),  or,  if  not  compliant,  obtaining  a  specific
authorization from the CNIL.

The most common standard methodologies are the following:

•

Decision  No.  2018-153  of  May  3,  2018  concerning  the  approval  of  a  standard  methodology  for  the  processing  of  personal  data
carried out within the context of research in the field of clinical

129

trials, which requires the express consent of the person involved (standard methodology MR-001)

•

•

Decision No. 2018-154 of May 3, 2018 concerning the approval of a standard methodology for the processing of personal data in the
context of research in the field of health, which does not require the express consent of the person involved (methodology MR-003).

Deliberation no. 2020-077 of June 18, 2020 adopting a framework relating to the retention periods of personal data processed for the
purposes of research, study or evaluation in the field of health.

In certain specific cases, entities processing health personal data may have to comply with article L1111-8 of the French Public Health Code
which imposes certain certifications for the hosting service providers.

C.    Organizational Structure.

On December 31, 2024, Innate Pharma is the sole shareholder of Innate Pharma Inc., a Delaware corporation.

D.    Property, Plants and Equipment.

Innate Pharma's corporate offices and laboratories are located in Luminy, Marseille, France and the Company owns the buildings and land.

United States.

Overview

Innate Pharma S.A. is a global, clinical-stage biotechnology company developing immunotherapies for cancer patients. Its innovative approach
aims to harness the innate immune system through three therapeutic approaches: monoclonal antibodies, multispecific NK Cell Engagers via its
ANKET®  (Antibody-based  NK  cell  Engager  Therapeutics)  proprietary  platform  and  Antibody  Drug  Conjugates  (ADC).  Innate’s  portfolio
includes its lead proprietary program lacutamab, developed in advanced form of cutaneous T cell lymphomas and peripheral T cell lymphomas,
monalizumab developed with AstraZeneca in non-small cell lung cancer, several ANKET® drug candidates to address multiple tumor types as
well as IPH4502 a differentiated ADC in development in solid tumors. Innate Pharma is a trusted partner to biopharmaceutical companies such
as Sanofi and AstraZeneca, as well as leading research institutions, to accelerate innovation, research and development for the benefit of patients.

130

Since  its  inception,  the  Company  has  devoted  substantially  all  of  its  financial  resources  to  research  and  development  efforts,  including
conducting  preclinical  studies  and  clinical  trials  of  its  product  candidates,  providing  general  and  administrative  support  for  its  operations  and
protecting its intellectual property.

As of December 31, 2024, the Company had €91.1 million in cash, cash equivalents, short-term investments and non-current financial assets.
Since its inception, the Company has raised a total of €314.3 million through the sale of equity securities, including €33.7 million in the initial
public offering of its ordinary shares on Euronext Paris in 2006 and €66.0 million in the initial public offering of our ordinary shares on Euronext
and ADS on The Nasdaq Global Select Market, or Nasdaq, in 2019. The main capital increases since 1999 are described in Item 5 - B Liquidity
and  Capital  Resources.  As  of  December  31,  2024,  the  Company  has  also  received  $656.1  million  (€579.1  million)  in  payments  from  its
collaborators, including AstraZeneca, since 2011, excluding payments received for purchases of its equity securities by its collaborators.

The Company has significant agreements with AstraZeneca and Sanofi pursuant to which it has the right to earn milestone and royalty payments.
The  Company  has  other  license  agreements,  pursuant  to  which  it  has  acquired  intellectual  property  and  under  which  the  Company  will  be
required  to  make  payments  to  the  counterparty  upon  the  achievement  of  certain  milestone  events  and  commercial  sales  related  to  its  product
candidates.

The Company has incurred net losses in each year since its inception except for the years ended December 31, 2016 and 2018. The Company net
income  (loss)  was  €(58.1)  million,  €(7.6)  million  and  €(49.5)  million  for  the  years  ended  December  31,  2022,  2023  and  2024,  respectively.
Substantially all of its net losses have resulted from costs incurred in connection with its research and development programs and from selling,
general and administrative expenses associated with its operations. As the Company continues advancing its product candidates through research
and  development  programs,  the  Company  expects  to  continue  to  incur  significant  expenses  and  may  again  incur  operating  losses  in  future
periods. The Company anticipates that such expenses will increase substantially if and as the Company:

•

•

•

•

•

•

•

•

•

•

•

•

•

continues the research and development of its product candidates;

initiates clinical trials for, or additional preclinical development of, its product candidates;

further develops and refines the manufacturing processes for its product candidates;

changes or adds manufacturers or suppliers of biological materials;

seeks regulatory and marketing authorizations for any of its product candidates that successfully complete development;

seeks to identify and validate additional product candidates;

acquires or licenses other product candidates, technologies or biological materials;

makes milestone, royalty or other payments under any current or future license agreements;

obtains, maintains, protects and enforces its intellectual property portfolio;

secures manufacturing arrangements for commercial production;

seeks to attract and retain new and existing skilled personnel;

creates additional infrastructure to support its operations as a U.S. public company and incurs increased legal, accounting, investor
relations and other expenses; and

experiences delays or encounters issues with any of the above.

131

The Company anticipates that it will need to raise additional funding, prior to completing clinical development of any of its product candidates.
Until such time that the Company can generate significant revenues from sales of its product candidates, if approved, the Company expects to
finance its operating activities through a combination of milestone payments received pursuant to its strategic alliances, equity offerings, debt
financings,  government  or  other  third-party  funding  and  collaborations,  and  licensing  arrangements.  However,  the  Company  may  not  receive
milestone payments when expected, or at all, and the Company may be unable to raise additional funds or enter into such arrangements when
needed on favorable terms, or at all, which would have a negative impact on its financial condition and could force the Company to delay, limit,
reduce or terminate its development programs or commercialization efforts or grant to others rights to develop or market product candidates that
the  Company  would  otherwise  prefer  to  develop  and  market  itself.  Failure  to  receive  additional  funding  could  cause  the  Company  to  cease
operations, in part or in full.

Presentation of Financial Information

The Company audited consolidated financial statements included herein as of and for the years ended December 31, 2022, 2023 and 2024 have
been prepared in accordance with IFRS as issued by the IASB.

Due to the listing of its ordinary shares on Euronext Paris and in accordance with the European Union’s regulation No. 1606/2002 of July 19,
2002, the Company also prepares and publishes its consolidated financial statements in accordance with IFRS as adopted by the European Union
(EU).

All the standards published by the IASB that are mandatorily applicable in the years ended December 2022, 2023 and 2024 are endorsed by the
EU and are mandatorily applicable in the EU. Therefore, the Company audited consolidated financial statements for the years ended December
31, 2022, 2023 and 2024 are compliant with both IFRS as issued by the IASB and IFRS as adopted by the EU.

The preparation of financial statements in accordance with IFRS requires the Company to make significant judgments and estimates which are
presented below. See “—Critical Accounting Policies and Significant Judgments and Estimates.”

Principal Collaboration and Licensing Agreements of the Company

The  Company  results  of  operations  are  impacted  by  the  terms  and  conditions  of  its  principal  collaboration  and  licensing  agreements.  For  a
description of its principal collaboration and licensing agreements, see “Item 10C.—Material Contracts.”

Principal Components of the Company Results of Operations

Revenue and other income

The Company revenue and other income mainly consists of revenues from collaboration and licensing agreements and government financing for
research expenditure in the form of research tax credits, as well as other grants.

Revenue from collaboration and licensing agreements

The Company currently derives substantially all its revenues from payments pursuant to its licensing and collaboration agreements notably with
AstraZeneca  relating  to  monalizumab  and  IPH5201,  Sanofi  relating  to  IPH6401/SAR'514  and  IPH62  consisting  of  (i)  upfront  payments,  (ii)
milestone  payments  based  upon  the  achievement  of  pre-determined  development,  regulatory  and  commercial  events  and  (iii)  research  and
development  fees  related  to  charges  for  full  time  equivalents,  or  FTEs,  at  contracted  rates  and  reimbursement  of  research  and  development
expenses.

As a consequence of the termination of the Lumoxiti Agreement, the Lumoxiti activity (including sales) is presented in the consolidated income
statement and the notes to the consolidated financial statements as a

132

discontinued operation for the 2023, 2022 and 2021 financial years in accordance with IFRS5 "non-current assets held for sale and discontinued
operations."

The  Company  ability  to  generate  significant  product  revenue  and  to  become  profitable  will  depend  upon  its  ability  to  successfully  develop,
obtain  regulatory  approval  for  and  commercialize  any  product  candidates.  Because  of  the  numerous  risks  and  uncertainties  associated  with
product development and regulatory approval, the Company is unable to predict the amount, timing or whether it will be able to obtain product
revenue from any such candidates.

Government financing for research expenditures

The Company's government financing for research expenditures consists of research tax credits (crédit d’impôt recherche) and grants.

The  research  tax  credit  is  granted  to  companies  by  the  French  tax  authorities  in  order  to  encourage  them  to  conduct  technical  and  scientific
research.  Companies  demonstrating  that  they  have  expenses  that  meet  the  required  criteria,  including  research  expenses  located  in  France  or,
since January 1, 2005, within the EU or in another state that is a party to the agreement in the European Economic Area that has concluded a tax
treaty with France that contains an administrative assistance clause, receive a tax credit which can be used against the payment of the corporate
tax due for the fiscal year in which the expenses were incurred and during the next three fiscal years, or, as applicable, can be reimbursed for the
excess portion. The expenditures taken into account for the calculation of the research tax credit involve only research expenses.

The main characteristics of the research tax credit are:

•

•

•

the research tax credit results in a cash inflow to the Company, i.e., it is used to offset the payment of corporate income tax the year
after the date of its record as a tax credit in the income statement, or is paid directly to the Company from the tax authorities for the
portion that remains unused, in principle, three years after the fiscal year for which it is determined;

The Company's corporate income tax liability does not limit the amount of the research tax credit. If the Company does not pay any
corporate income tax, the Company can offset the remaining research tax credit the year following its record in the income statement;
and

the research tax credit is not included in the determination of the corporate income tax.

When the research tax credit is not deductible from taxes payable by the Company, it is generally reimbursed by the French government three
years  after  the  fiscal  year  for  which  it  is  determined.  However,  since  2011,  companies  that  meet  the  definition  of  small  and  medium  sized
enterprises (“SMEs”) according to the European Union criteria are eligible for early reimbursement of their research tax credit receivable. The
status of SME is lost when the criteria for eligibility are exceeded during two consecutive years. The Company lost its SME status at the end of
the 2019 fiscal year but has been eligible again since the end of the 2021 financial year. Since December 31, 2023, the company lost again the
SME status due to two consecutive year with a statutory turnover over €50,000 thousand. For more information, see “Item 5.B—Liquidity and
Capital Resources—Sources and uses of liquidity.”

The  Company  has  concluded  that  the  research  tax  credit  meets  the  definition  of  a  government  grant  as  defined  in  IAS  20  Accounting  for
government  grants  and  disclosure  of  government  assistance  (IAS  20),  and  that  the  classification  as  “Revenue  and  other  income”  in  its
consolidated statement of income (loss) is appropriate.

133

Innate may also be eligible to receive other government grants, which are recognized in its consolidated statement of income (loss) when Innate
complies with the conditions attached to the grants, and the latter are non-repayable grants.

Operating expenses from continuing operations

Since its inception, Innate's operating expenses have consisted primarily of research and development expenses and general and administration
expenses.

Following  the  transfer  back  of  the  U.S.  marketing  authorization  to  AstraZeneca  linked  to  the  Termination  and  Transition  Agreement  (from
October 1, 2021), selling expenses relating to Lumoxiti activities are presented as discontinued operations since December 31, 2021. The 2020
and  2019  comparatives  have  been  restated  compared  to  previous  publications,  in  accordance  with  the  same  standard  (see  "Discontinued
Operations" below).

Research and development expenses

The  Company  engages  in  substantial  research  and  development  efforts  to  develop  innovative  product  candidates.  Research  and  development
expenses consist primarily of:

•

•

•

•

personnel  costs,  including  salaries,  related  benefits  and  share-based  compensation,  for  Innate's  employees  engaged  in  scientific
research and development functions;

cost  of  third-party  contractors  and  academic  institutions  involved  in  preclinical  studies  or  clinical  trials  that  the  Company  may
conduct, or third-party contractors involved in field trials;

purchases of biological raw materials, real estate leasing costs as well as conferences and travel costs; and

certain other expenses, such as expenses for use of laboratories and facilities for Innate's research and development activities as well
as depreciation and amortization.

Innate's research and development efforts are focused on its existing product candidates and preclinical programs, including the advancement of
its  lead  product  candidates,  monalizumab,  lacutamab.  Its  direct  research  and  development  expenses  consist  principally  of  external  costs
associated with subcontracting of preclinical and clinical operations to third parties, which Innate tracks on a program-by-program basis. The
Company  also  uses  its  employee  and  infrastructure  resources  across  multiple  research  and  development  programs,  and  does  not  track  these
indirect expenses on a program-by-program basis.

Research and development costs are expensed as incurred. Costs for certain activities are recognized based on an evaluation of the progress to
completion of specific tasks using data such as information provided to Innate Pharma by its vendors and analyzing the progress of its preclinical
studies or other services performed. Significant judgment and estimates are made in determining the accrued expense balances at the end of any
reporting  period.  Non-refundable  advance  payments  for  research  and  development  goods  or  services  to  be  received  in  the  future  from  third
parties are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the services are performed.

Research and development activities are central to Innate's business. As product candidates in later stages of clinical development generally have
higher  development  costs  than  those  in  earlier  stages  of  clinical  development,  primarily  due  to  the  increased  size  and  duration  of  later-stage
clinical  trials,  the  Company  expects  that  its  research  and  development  costs  will  increase  in  the  foreseeable  future.  Such  cost  increases  are
expected to occur as the Company conducts existing clinical trials and initiates future clinical trials, manufactures pre-commercial clinical trial
and  preclinical  study  materials,  expands  its  research  and  development  efforts,  seeks  regulatory  approvals  for  its  product  candidates  that
successfully complete

134

clinical trials, accesses and develops additional technologies and hires additional personnel to support its research and development efforts.

The Company cannot determine with certainty the duration and total costs of its future clinical trials of its product candidates or if, when, or to
what  extent  it  will  generate  revenues  from  the  commercialization  and  sale  of  any  of  its  product  candidates,  or  those  of  its  collaborators,  that
might obtain regulatory approval. The Company may never succeed in achieving regulatory approval for any product candidates. The duration,
costs and timing of clinical trials and development of its product candidates will depend on a variety of factors, including:

•

•

•

•

•

the  scope,  rate  of  progress  and  expense  of  its  ongoing  clinical  trials  as  well  as  any  additional  preclinical  studies,  clinical  trials
conducted by its collaborators and other research and development activities;

clinical trial and preclinical study results;

the terms and timing of regulatory approvals;

the expense of filing, maintaining, prosecuting, defending and enforcing patent claims and other intellectual property rights; and

the ability to market, commercialize and achieve market acceptance for any products that receive regulatory approval.

A change in the outcome of any of these variables with respect to the development of monalizumab, lacutamab or any other product candidate or
preclinical  program  that  the  Company  is  developing  or  could  develop  in  the  future  could  mean  a  significant  change  in  the  costs  and  timing
associated with the development of such product candidates or preclinical programs. For example, if the FDA, the EMA or another regulatory
authority were to require Innate to conduct preclinical studies and clinical trials beyond those that it currently anticipates will be required for the
completion of clinical development, or if the Company experiences significant delays in enrollment in any clinical trials, the Company could be
required  to  spend  significant  additional  financial  resources  and  time  on  the  completion  of  clinical  development.  For  a  discussion  of  the  risks
associated  with  completing  the  development  projects  on  schedule,  see  “Risk  Factors—Risks  Related  to  the  Development  of  the  Product
Candidates.”

General and administrative expenses

General and administrative expenses consist primarily of personnel costs and share-based compensation for personnel other than research and
development  staff.  Selling,  general  and  administrative  expenses  also  consist  of  fees  for  professional  services,  mainly  related  to  audit,  IT,
accounting,  recruitment  and  legal  services,  communication  and  travel  costs,  real-estate  leasing  costs,  office  furniture  and  equipment  costs,
allowance  for  amortization  and  depreciation,  director’s  attendance  fees  and  insurance  costs  and  overhead  costs,  such  as  postal  and
telecommunications expenses.

Net financial income (loss)

The financial income (loss) primarily consists of realized and unrealized foreign exchange gains and losses primarily related to the purchase of
services  as  well  as  deposit  accounts  denominated  in  U.S.  dollars  and  gains  and  losses  and  interest  received  in  relation  to  cash  and  cash
equivalents that have been deposited in cash accounts, short-term fixed deposits and short-term highly liquid investments with original maturities
of three months or less. Thus, the Company's financial assets generated €2.4 million of interest income in the financial year ended December 31,
2024. Innate expects to continue this investment philosophy in the future.

135

Net result from discontinued operations

Pursuant to the Termination and Transition Agreement, in the year ended December 31, 2020 results announcement, the Company reported a
contingent liability of up to $12.8 million in its consolidated financial statements, which was related to the splitting of certain manufacturing
costs. As part of the Termination and Transition Agreement, Innate and AstraZeneca agreed to split these manufacturing costs, and Innate paid
$6.2 million (€5.9 million) to AstraZeneca on April 30, 2022.

As a consequence of the termination of the Lumoxiti Agreement, the Lumoxiti activity (including sales) is presented in the consolidated income
statement  and  the  notes  to  the  consolidated  financial  statements  as  a  discontinued  operation  for  the  2024,  2023  and  2022  financial  years  in
accordance  with  IFRS5  "non-current  assets  held  for  sale  and  discontinued  operations."  Therefore,  since  December  31,  2020  the  income
statement and subsequent years have been prepared with the Lumoxiti activity (including sales) as a discontinued operation in accordance with
the same IFRS standard.The Lumoxiti activity has not had an impact on the consolidated income statement since 2022.

Impairment of intangible assets

The  Group  assesses  at  the  end  of  each  reporting  period  whether  there  is  an  indication  that  intangible  assets,  property  and  equipment  may  be
impaired. If any indication exists, the Group estimates the recoverable amount of the related asset.

Whether or not there is any indication of impairment, intangible assets not yet available for use are tested for impairment annually by comparing
their carrying amount with their recoverable amount.

Pursuant to IAS 36—Impairment of Assets, criteria for assessing indication of loss in value may notably include performance levels lower than
forecast, a significant change in market data or the regulatory environment, or obsolescence or physical damage of the asset not included in the
amortization/depreciation  schedule.  The  recognition  of  an  impairment  loss  alters  the  amortizable/depreciable  amount  and  potentially,  the
amortization/depreciation schedule of the relevant asset.

As  of  December  31,  2022,  impairment  of  intangible  assets  consisted  of  the  full  depreciation  of  avdoralimab  rights  for  an  amount  of  €41.0
million,  following  the  Company's  decision  to  stop  avdoralimab  development  in  bullous  phemphigoid  ("BP")  indication  in  inflammation
following a decision taken by a sponsor to stop the Phase 2 clinical trial in said indication during the fourth quarter of 2022.

Revenue from collaboration and licensing agreements

Revenue  from  collaboration  and  licensing  agreements  from  continuing  operations  decreased  by  €39.3  million,  to  €12.6  million  for  the  year
ended December 31, 2024, as compared to revenue from collaboration and licensing agreements of €51.9 million for the year ended December

Revenue from collaboration and licensing agreements mainly resulted from the partial or entire recognition of the proceeds received pursuant to
the agreements with AstraZeneca signed in April 2015 and October 2018, as well as the agreement signed with Sanofi in 2016 and 2022 and also
with Takeda in 2023. Proceeds are recognized on the basis of the percentage of completion of the works performed by the Company under such
agreements.

Revenue from collaboration and licensing agreements is set forth in the table below.

Proceeds related to monalizumab.

Revenues  related  to  monalizumab  result  from  the  partial  recognition  of  the  $250.0  million  non-refundable  upfront  payment  and  the  $100.0
million milestone resulting from the exercise of the option received in June 2015 and October 2018 from AstraZeneca. The additional payment
of $50.0 million (€47.7 million) received from AstraZeneca in December 2020 triggered by the dosing of the first patient in the Phase 3

138

 
 
 
 
 
 
trial evaluating monalizumab was treated in full as a collaboration commitment ("collaboration liability" in the consolidated balance sheet) in
view to the commitment linked to the agreement for the Phase 1/2 (co-financing) and Phase 3 studies (amendment signed in September 2020).
For  more  information,  see  Note  1.1  to  the  consolidated  financial  statements  are  included  as  part  of  this  Annual  Report.  Consequently,  this
additional payment has no impact on the transaction price.

In addition to these amounts, AstraZeneca made an additional payment of $50.0 million (€47.7 million) in June 2022, triggered by the treatment
of the first patient in a second Phase 3 trial evaluating monalizumab in April 2022. This additional payment has been treated as a collaboration
commitment ("collaboration liability" in the consolidated balance sheet) for an amount of $36.0 million (€34.3 million) in view to the contractual
commitment  linked  to  the  Phase  1/2  studies  (co-funding  under  the  initial  contract).  The  remaining  $14.0  million  was  treated  as  a  change  in
estimate of the transaction price, recognized in the income statement in line with the progress of the Phase 1/2 studies.

Revenue related to monalizumab decreased by €5.1 million, to €4.4 million for the year ended December 31, 2024, as compared to €9.5 million
for the year ended December 31, 2023. This €5.1 million decrease is primarily explained by the accounting of an exceptional revenue catch-up
during the first half of 2023. Indeed, as of June 30, 2023, the Company had conducted an analysis of the cost basis used to calculate the progress
of Phase 1/2 trials in light of their advancement. This analysis led to a reduction in this cost basis through a reassessment of projected expenses.
Consequently,  this  adjustment  to  the  cost  basis  had  a  positive  impact  on  the  percentage  of  completion  and  resulted  in  the  recognition  of  an
additional revenue of €5.9 million for the first half of 2023, which did not recur in 2024. As of December 31, 2024, the amount not recognized as
revenue amounted to €0.2 million, and is presented in full under "Current contract liabilities" given the maturity of the Phase 1/2 trials.

Proceeds related to IPH5201.

Revenue related to IPH5201 for the year ended December 31, 2024 is $0.0 same as year ended December 31, 2023, compared with $5.0 million
(€4.7 million) for the year 2022. This revenue related to the milestone payment received from AstraZeneca following the signature on June 1,
2022  of  an  amendment  to  the  initial  contract  signed  in  October  2018.  This  amendment  sets  the  terms  of  the  collaboration  following
AstraZeneca’s decision to advance IPH5201 to a Phase 2 study. The Company will conduct the study. Both parties will share the external cost
related  to  the  study  and  incurred  by  the  Company  and  AstraZeneca  will  provide  products  necessary  to  conduct  the  clinical  trial.  For  more
information  on  this  amendment,  see  Note  1.1  to  the  consolidated  financial  statements  included  under  "Item  18.  Financial  Statements"  of  this
Annual Report.

Invoicing of research and development costs - IPH5201.

Pursuant  to  the  Company's  agreements  with AstraZeneca,  research  and  development  costs  related  to  IPH5201  in  connection  with  preclinical
work  are  fully  borne  by  AstraZeneca,  in  accordance  with  the  initial  2018  agreement.  These  costs  were  re-invoiced  on  a  quarterly  basis.
Following  the  signature  on  June  1,  2022  of  an  amendment  to  the  initial  agreement  signed  in  October  2018  specifying  the  terms  of  the
collaboration following the decision to advance IPH5201 to a Phase 2 study, the parties are committed to sharing the external costs of the study
incurred by the Company and AstraZeneca will provide products necessary to conduct the clinical trial.

Revenue from invoicing of research and development costs for the year ended December 31, 2024 was €2.1 million compared to €1.2 million for
the year ended December 31, 2023, or a increase of € 0.9 million.

Proceeds related to Sanofi 2016 agreement.

139

Revenues under the collaboration and license agreement signed with Sanofi in 2016 amounted to €4.0 million for the year ended December 31,
2024 as compared to €2.0 million for the year ended December 31, 2023. On April 15, 2024, the Company announced the treatment of the first
patient in the dose-expansion phase 2 of the study conducted by Sanofi evaluating the NK Cell Engager IPH6101/SAR443579 in various blood
cancers. According to the terms of the 2016 agreement, this trial progression triggered a milestone payment of €4.0 million, fully recognized as
revenue during the first quarter of 2024, and was received by the Company on May 17, 2024

Proceeds related to Sanofi 2022 agreement

On  December  19,  2022,  the  Company  announced  that  it  had  entered  into  a  research  collaboration  and  license  agreement  with  Genzyme
Corporation, a wholly-owned subsidiary of Sanofi (“Sanofi”) pursuant to which the Company granted Sanofi an exclusive license on the Innate
Pharma's B7-H3 ANKET  program and options on two additional targets. On January 25, 2023, the Company announced the expiration of the
waiting period under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976 and the effectiveness of the licensing agreement as of
January 24, 2023. Consequently, the Company received an upfront payment of €25.0 million in March 2023, including €18.5 million relating to
the exclusive license, €1.5 million relating to the research work and €5.0 million relating to the two additional targets options.

®

The Company considers that the license to the B7-H3 technology is a right to use the intellectual property granted exclusively to Sanofi as from
the effective date of the agreement. As such, the €18.5 million upfront payment relating to the exclusive license has been fully recognized in
revenue since June 2023.

The Company will provide collaborative research services to Sanofi for an initial estimated three years period as from the effective date of the
collaboration, i.e., January 24, 2023. During this period, Sanofi and Innate will collaborate and work on research activities as defined in the work
program described in the agreement. Consequently, the corresponding upfront payment of €1.5 million will be recognized on a straight-line basis
over the duration of the research services that the Company has agreed to carry out. As a result, a €0.8 million has been recognized in revenue as
of  December  31,  2024,  and  amounts  not  recognized  in  revenue  are  classified  as  deferred  revenue  current  portion  equal  to  €0.4  million  and
deferred revenue non-current portion equal to €0.3 million.

Under the terms of this agreement, the Company has also granted two exclusive options, exercisable no later than three years after the effective
date,  for  exclusive  licenses  to  Innate's  intellectual  property  for  the  research,  development,  manufacture  and  commercialization  of  NKCEs
specifically targeting two preclinical molecules. The Company considers that the option to acquire an exclusive license provide a material right
to Sanofi that it would not receive without entering into this agreement. The Company will recognize the related revenues either at the reporting
date or three years after the effective date. Consequently, the €5.0 million initial payment relating to these options was recognized in deferred
revenue—non-current portion as of June 30, 2023.

On December 19, 2023, the Company announced that Sanofi had exercised an option for one of the two preclinical molecules. As a consequence,
the Company recognized related income of €2.5 million as of December 31, 2023.

This option exercise also resulted in a milestone payment of €15.0 million, including €13.3 million in respect of the exclusive license, which was
fully recognized in income as of December 31, 2023, and €1.7 million in respect of research services to be carried out by the Company. Sanofi
and Innate will collaborate and work on the research activities defined in the contractual work program. Consequently, the corresponding initial
payment of €1.7 million will be recognized on a straight-line basis over the duration of the research work that the Company has agreed to carry
out. This work had not yet begun as of December 31, 2023. In this respect, no revenue has been recognized in the income statement, and the

140

amount of €1.7 million is presented under current contract liabilities (€0.4 million) and non-current contract liabilities (€1.3 million).

On  October  9,  2024,  the  Company  received  a  termination  letter  for  the  license  agreement  concerning  this  option.  The  termination  ends  the
research work. The revenue of €1.7 million was therefore fully recognized as revenue on December 31, 2024.

Innate has regained full rights to IPH67, a NK Cell Engager program derived from the ANKET® platform currently in development for solid
tumors. Sanofi retains a right to a low single-digit compensation regarding any future revenue that Innate Pharma may receive for licenses of
IPH67, as well as payments based on milestones should the Company develop IPH67 itself, and an ongoing royalty fee in the low-single digits.

Under the terms of the agreement, Sanofi still retains a license option for a third preclinical molecule.

Proceeds related to Takeda agreement

On April  3,  2023,  the  Company  announced  that  it  has  entered  into  an  exclusive  license  agreement  with  Takeda  under  which  Innate  granted
Takeda exclusive worldwide rights to research and develop ADCs using a panel of selected Innate antibodies against an undisclosed target, with
a primary focus in Celiac disease. Takeda would have beeen responsible for the future development, manufacture and commercialization of any
potential  products  developed  using  the  licensed  antibodies. As  such,  the  Company  considered  that  the  license  granted  was  a  right  to  use  the
relevant intellectual property, which was granted fully and perpetually to Takeda. The agreement did not stipulate that Innate's activities would
significantly  affect  the  intellectual  property  granted  during  the  life  of  the  agreement.  Consequently,  the  $5.0  million  (or  €4.6  million)  initial
payment, received by the Company in May 2023, was fully recognized in revenue since June 30, 2023. Given Takeda’s strategic decision in July
2024 to terminate the license agreement executed in March 2023 for use of selected Innate antibodies in antibody drug-conjugates, no further
revenue  is  recognized  under  this  agreement  with  Takeda.  The  Company  does  not  intend  at  this  stage  to  continue  the  development  of  these
antibodies.

Government financing for research expenditures

Government funding for research expenditures decreased by €2.2 million, or (23.03)%, to €7.5 million for the year ended December 31, 2024, as
compared to €9.7 million for the year ended December 31, 2023. As a reminder, the 2023 research tax credit included a reduction of €0.1 million
related  to  a  provision  following  the  tax  inspection  carried  out  in  2022  by  the  French  tax  authorities.  The  provision  estimated  in  2022  was
adjusted after the reception of final tax authority decision.

The table below details government funding for research expenditures for the years ended December 31, 2023 and 2024.

1. 2023 expenses from program IPH6501 were reported in 2023 20-F in sub-total programs in preclinical development. Following first patient dosed in June 2024, this program is now in clinical

stage therefore we have reclassed 2023 expenses in the sub-total programs in clinical development

2. Total direct research and development expenses are composed of subcontracting costs and cost of supplies and consumables materials.

Research  and  development  expenses  from  continuing  operations  decreased  by  €4.0  million,  or  7.2%,  to  €52.0  million  for  the  year  ended
December 31, 2024, as compared to research and development expenses of €56.0 million for the year ended December 31, 2023. This decrease
over the period is mainly due to (i) a decrease in direct research and development expenses of €1.9 million over the period due mainly to the
decrease  in  expenses  related  to  more  mature  clinical  development  programs,  and  (ii)  indirect  expenses  which  have  decreased  by  €2.2  million
mainly  in  depreciation  and  amortization.  Research  and  development  expenses  represented  a  total  of  72.5%  and  75.4%  of  operating  expenses
before impairment for years ended December 31, 2024 and December 31, 2023, respectively.

Direct  research  and  development  expenses  decreased  by  €1.9  million,  or  6.2%,  to  €28.3  million  for  the  year  ended  December  31,  2024,  as
compared to direct research and development expenses of €30.2 million for the year ended December 31, 2023. This decrease is mainly due to a
€2.3 million increase in expenses related to preclinical development programs relating notably to the ADC field, partly offset by a €4.2 million
decrease in expenses related to the Company's clinical programs. This decrease in clinical programs expenses mainly results from a €0.7 million
decrease in expenses relating to the monalizumab program and a €3.3 million decrease in expenses relating to the lacutamab program, partly
offset  by  a  €1.7  million  increase  in  expenses  related  to  the  growth  in  IPH5201  phase  2  trials  patient  recruitment.  In  addition,  In  addition,
IPH6501 moved from pre-clinical to Phase 1 clinical development in June 24, with the first patient dosed. Costs decreased by € 1.9 million due
to lower research and development expenses, partially offset by expenses related to the commencement of clinical trial.

As  of  December  31,  2024,  the  collaboration  liabilities  relating  to  monalizumab  and  the  agreements  signed  with AstraZeneca  in April  2015,
October  2018  and  September  2020  amounted  to  €48.6  million,  as  compared  to  collaborations  liabilities  of  €52.7  million  as  of  December  31,
2023. This decrease of €4.1

143

 
 
 
million mainly results from (i) net repayment of €7.8 million during year 2024 to AstraZeneca linked to the Monalizumab cofinancing program,
including  phase  3  trial  INTERLINK-1  launched  in  October  2020  and  PACIFIC-9  launched  in  April  2022,  and  (ii)  the  increase  of  the
collaboration commitment ("collaboration liabilities" in the consolidated statements of financial position) for an amount of €3.6 million linked to
the Euro-dollar parity exchange rate variation.

Personnel  and  other  expenses  allocated  to  research  and  development  decreased  by  €2.2  million,  or  8.4%,  to  €23.7  million  for  the  year  ended
December 31, 2024, as compared to an amount of €25.8 million for the year ended December 31, 2023. This decrease is due to (i) decrease of
€2.8 million in depreciation and amortization, mainly composed of the amortization of the monalizumab and IPH5201 intangible assets. (ii) €0.4
million  increase  in  staff  costs  allocated  to  research  and  development,  of  which  €0.2  million  in  personnel  expenses  and  €0.2  million  in  share-
based payment expenses, .

As  of  December  31,  2024,  the  Company  had  139  employees,  including  Leadership  Team  members,  in  research  and  development  functions,
compared to 140 as of December 31, 2023.

General and administrative expenses

General  and  administrative  expenses  from  continuing  operations  increased  by  €1.4  million,  or  7.8%,  to  €19.7  million  for  the  year  ended
December 31, 2024, as compared to €18.3 million for the year ended December 31, 2023. General and administrative expenses represented a
total of 27.5% and 24.6% of our total operating expenses before impairment for the years ended December 31, 2024 and 2023, respectively.

expenses.

Personnel expenses, which includes the compensation paid to our employees and consultants, decreased by €0.3 million, or 3.2%, to €8.6 million
for the year ended December 31, 2024, as compared to personnel expenses of €8.8 million for the year ended December 31, 2023. This decrease
mainly  results  from  €0.5  million  decrease  in  share-based  payment  expenses  compensated  by  an  increase  in  wages  of  €(0.2)  million.  As  of
December 31, 2024, we had 42 employees, including Leadership Team members, in general and administrative functions, as compared to 39 as
of December 31, 2023.

Non-scientific advisory and consulting expenses mostly consist of auditing, accounting, legal and hiring services. These expenses increased by
€0.5 million, or 16.2%, to €3.4 million for the year ended December 31, 2024, as compared to an amount of €2.9 million for the year ended
December 31, 2023.

144

 
 
 
This increase is mainly due to the use of recruitment agencies to set up the clinical department and to recruit the new Chairman of the Executive
Board.

Other  general  and  administrative  expenses  relate  to  intellectual  property,  depreciation  and  amortization  and  other  general,  administrative
expenses. These expenses increased by €1.2 million or 19.0% to €7.8 million for the year ended December 31, 2024, as compared to an amount
of €6.5 million for the year ended December 31, 2023, is primarily related to the repayment of interest on the 2023 R&D Tax Credit amounting
to €0.8 million, the rise in IT service costs of €0.1 million and the impact of IFRS 16 following the restitution of leased spaces, which generated
a non-recurring credit of €0.2 million in 2023.

Impairment of intangible assets

As a reminder, for the year ended December 31, 2022, impairment of intangible assets results from full impairment of anti-C5aR rights acquired
from  Novo/Nordisk A/S  (avdoralimab  intangible  asset)  for  an  amount  of  €41.0  million.  During  the  fourth  quarter  of  2022,  the  Company  was
informed  by  the  sponsor  of  the  Phase  2  clinical  trial  evaluating  avdoralimab  in  inflammation  in  bullous  pemphigoid  ("BP")  indication  of  its
decision to stop said trial. Consequently, the Company decided in December 2022 to stop the development of avdoralimab in BP indication in
inflammation,  only  indication  supporting  the  recoverable  amount  of  the  asset  as  of  December  31,  2021  (as  well  that  as  of  June  30,  2022).
Without any new event since then, the impairment has not been reassessed.

Financial income (loss), net

The net financial result decreased by €3.0 million, to a €2.1 million profit for the year ended December 31, 2024, as compared to a €5.1 million
loss for the year ended December 31, 2023. This change mainly results from the net foreign exchange loss of €1.8 million (net foreign exchange
gain of €0.9 million in 2023), interest income on financial investments (net gain of €2.4 million in 2024 compared to €3.2 millions in 2023) and
the change in the fair value of certain financial instruments (net gain of €2.0 million in 2024 as compared to a net gain of €1.6 million in 2023).

Revenues from collaboration and licensing agreements

Revenue from collaboration and licensing agreements from continuing operations increased by €2.3 million, to €51.9 million for the year ended
December  31,  2023,  as  compared  to  revenue  from  collaboration  and  licensing  agreements  of  €49.6  million  for  the  year  ended  December  31,
2022.

Revenue from collaboration and licensing agreements mainly resulted from the partial or entire recognition of the proceeds received pursuant to
the agreements with AstraZeneca signed in April 2015 and October 2018, as well as the agreement signed with Sanofi in 2016 and 2022 and also
with Takeda in 2023. Proceeds are recognized on the basis of the percentage of completion of the work performed by the Company under such
agreements.

Revenue from collaboration and licensing agreements is set forth in the table below.

Proceeds related to monalizumab.

Revenues  related  to  monalizumab  result  from  the  partial  recognition  of  the  $250.0  million  non-refundable  upfront  payment  and  the  $100.0
million milestone resulting from the exercise of the option received in June 2015 and October 2018 from AstraZeneca. The additional payment
of $50.0 million (€47.7 million) received from AstraZeneca in December 2020 triggered by the dosing of the first patient in the Phase 3 trial
evaluating monalizumab was treated in full as a collaboration commitment ("collaboration liability" in the consolidated balance sheet) in view to
the commitment linked to the agreement for the Phase 1/2 (co-financing) and Phase 3 studies (amendment signed in September 2020). For more
information,  see  Note  1.1  to  the  consolidated  financial  statements  included  under  "Item  18.  Financial  Statements"  of  this  Annual  Report.
Consequently, this additional payment has no impact on the transaction price.

In addition to these amounts, AstraZeneca made an additional payment of $50.0 million (€47.7 million) in June 2022, triggered by the treatment
of the first patient in a second Phase 3 trial evaluating monalizumab in April 2022. This additional payment has been treated as a collaboration
commitment ("collaboration liability" in the consolidated balance sheet) for an amount of $36.0 million (€34.3 million) in view to the contractual
commitment  linked  to  the  Phase  1/2  studies  (co-funding  under  the  initial  contract).  The  remaining  $14.0  million  was  treated  as  a  change  in
estimate of the transaction price, recognized in the income statement in line with the progress of the Phase 1/2 studies.

Revenue  related  to  monalizumab  decreased  by  €12.9  million,  to  €9.5  million  for  the  year  ended  December  31,  2023,  as  compared  to  €22.4
million for the year ended December 31, 2022. This €12.9 million decrease mainly resulted from to the increase, in the first half of 2022, in the
transaction price of €13.4 million ($14.0 million) triggered by the launch of the PACIFIC-9 Phase 3 trial on April 28, 2022. As a reminder, this
increase in the transaction price led to the recognition of additional income of €12.6 million in the income related to the monalizumab agreement
for 2022. As of December 31, 2023, the amount not recognized as revenue amounted to €5.2 million, and is presented in full under "Current
contract liabilities" given the maturity of the Phase 1/2 trials.

Proceeds  related  to  IPH5201.  Revenue  related  to  IPH5201  for  the  year  ended  December  31,  2023  is  $0.0  compared  with  $5.0  million  (€4.7
million) for the year 2022. This revenue related to the milestone payment received from AstraZeneca following the signature on June 1, 2022 of
an  amendment  to  the  initial  contract  signed  in  October  2018.  This  amendment  sets  the  terms  of  the  collaboration  following  AstraZeneca’s
decision to advance IPH5201 to a Phase 2 study. The Company will conduct the study. Both parties will share the external cost related to the
study and incurred by the Company and AstraZeneca will provide products necessary to conduct the clinical trial. For more information on this
amendment, see Note 1.1 to the consolidated financial statements included under "Item 18. Financial Statements" of this Annual Report.

Proceeds related to collaboration and option agreement related to four to-be-agreed upon molecules (preclinical molecules).

During the first half of 2022, the Company received from AstraZeneca a notice that it will not exercise its option to license the four preclinical
programs  covered  in  the  "Future  Programs  Option  Agreement."  This  license  option  was  part  of  the  2018  multi-term  agreement  between
AstraZeneca and the Company under which the Company had received an upfront payment of $20.0 million (€17.4 million). As the rights related
to  these  four  preclinical  programs  have  been  returned  to  the  Company,  the  entire  upfront  payment  of  $20.0  million  (€17.4  million)  has  been
recognized as revenue as of June 30, 2022.

Invoicing of research and development costs - IPH5201.

149

Pursuant  to  the  Company's  agreements  with AstraZeneca,  research  and  development  costs  related  to  IPH5201  in  connection  with  preclinical
work  are  fully  borne  by  AstraZeneca,  in  accordance  with  the  initial  2018  agreement.  These  costs  were  re-invoiced  on  a  quarterly  basis.
Following  the  signature  on  June  1,  2022  of  an  amendment  to  the  initial  agreement  signed  in  October  2018  specifying  the  terms  of  the
collaboration following the decision to advance IPH5201 to a Phase 2 study, the parties are committed to sharing the external costs of the study
incurred by the Company and AstraZeneca will provide products necessary to conduct the clinical trial.

Revenue from invoicing of research and development costs for the year ended December 31, 2023 was €1.2 million compared to €1.4 million for
the year ended December 31, 2022, or a decrease of € 0.2 million.

Proceeds related to Sanofi 2016 agreement.

Revenues under the collaboration and license agreement signed with Sanofi in 2016 amounted to €2.0 million for the year ended December 31,
2023 as compared to €4.0 million for the year ended December 31, 2022. The Company announced that, in June 2023, the first patient was dosed
in  a  Sanofi-sponsored  Phase  1/2  clinical  trial  evaluating  IPH6401/SAR'514  in  relapsed  or  refractory  Multiple  Myeloma. As  provided  by  the
licensing agreement signed in 2016, Sanofi made a milestone payment of €2.0 million, fully recognized in revenue since June 2023. This amount
was  received  by  the  Company  on  July  21,  2023. As  a  reminder,  the  revenue  recognized  in  2022  resulted  from  Sanofi's  decision  to  advance
IPH6401/SAR'514  towards  regulatory  preclinical  studies  for  a  new  investigational  drug. This  decision  triggered  a  milestone  payment  of  €3.0
million fully recognized in revenue. This amount was received by the Company on September 9, 2022.

Proceeds related to Sanofi 2022 agreement

On  December  19,  2022,  the  Company  announced  that  it  had  entered  into  a  research  collaboration  and  license  agreement  with  Genzyme
Corporation, a wholly-owned subsidiary of Sanofi (“Sanofi”) pursuant to which the Company granted Sanofi an exclusive license on the Innate
Pharma's B7-H3 ANKET  program and options on two additional targets. On January 25, 2023, the Company announced the expiration of the
waiting period under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976 and the effectiveness of the licensing agreement as of
January 24, 2023. Consequently, the Company received an upfront payment of €25.0 million in March 2023, including €18.5 million relating to
the exclusive license, €1.5 million relating to the research work and €5.0 million relating to the two additional targets options.

®

The Company considers that the license to the B7-H3 technology is a right to use the intellectual property granted exclusively to Sanofi as from
the effective date of the agreement. As such, the €18.5 million upfront payment relating to the exclusive license has been fully recognized in
revenue since June 2023.

The Company will provide collaborative research services to Sanofi for an initial estimated three years period as from the effective date of the
collaboration, i.e., January 24, 2023. During this period, Sanofi and Innate will collaborate and work on research activities as defined in the work
program described in the agreement. Consequently, the corresponding upfront payment of €1.5 million will be recognized on a straight-line basis
over the duration of the research services that the Company has agreed to carry out. As a result, a €0.4 million has been recognized in revenue as
of  December  31,  2023,  and  amounts  not  recognized  in  revenue  are  classified  as  deferred  revenue—current  portion  equal  to  €0.3  million  and
deferred revenue—non-current portion equal to €0.8 million.

Under the terms of this agreement, the Company has also granted two exclusive options, exercisable no later than three years after the effective
date,  for  exclusive  licenses  to  Innate's  intellectual  property  for  the  research,  development,  manufacture  and  commercialization  of  NKCEs
specifically targeting two

150

preclinical molecules. The Company considers that the option to acquire an exclusive license provide a material right to Sanofi that it would not
receive without entering into this agreement. The Company will recognize the related revenues either at the reporting date or three years after the
effective date. Consequently, the €5.0 million initial payment relating to these options was recognized in deferred revenue—non-current portion
as of June 30, 2023.

On December 19, 2023, the Company announced that Sanofi had exercised an option for one of the two preclinical molecules. As a consequence,
the Company recognized related income of €2.5 million as of December 31, 2023.

This option exercise also resulted in a milestone payment of €15.0 million, including €13.3 million in respect of the exclusive license, which was
fully recognized in income as of December 31, 2023, and €1.7 million in respect of research services to be carried out by the Company. Sanofi
and Innate will collaborate and work on the research activities defined in the contractual work program. Consequently, the corresponding initial
payment of €1.7 million will be recognized on a straight-line basis over the duration of the research work that the Company has agreed to carry
out. This work had not yet begun as of December 31, 2023. In this respect, no revenue has been recognized in the income statement, and the
amount of €1.7 million is presented under current contract liabilities (€0.4 million) and non-current contract liabilities (€1.3 million).

Under the terms of the agreement, Sanofi still retains a license option for a third preclinical molecule.

Proceeds related to Takeda agreement

On April  3,  2023,  the  Company  announced  that  it  has  entered  into  an  exclusive  license  agreement  with  Takeda  under  which  Innate  granted
Takeda exclusive worldwide rights to research and develop ADCs using a panel of selected Innate antibodies against an undisclosed target, with
a primary focus in Celiac disease. Takeda would be responsible for the future development, manufacture and commercialization of any potential
products developed using the licensed antibodies. As such, prior to the termination of this agreement, the Company considered that the license
granted was a right to use the relevant intellectual property, which was granted fully and perpetually to Takeda. The agreement did not stipulate
that Innate's activities would significantly affect the intellectual property granted during the life of the agreement. Consequently, the $5.0 million
(or €4.6 million) initial payment, received by the Company in May 2023, was fully recognized in revenue since June 30, 2023.

Government financing for research expenditures

Government funding for research expenditures increased by €1.7 million, or 21.08%, to €9.7 million for the year ended December 31, 2023, as
compared to €8.0 million for the year ended December 31, 2022. As a reminder, the 2022 research tax credit included a reduction of €1.3 million
related  to  a  provision  following  the  tax  inspection  carried  out  in  2022  by  the  French  tax  authorities.  This  provision  was  based  on  estimated
amounts and adjustments not disputed by the Company and has been increased in 2023 for €0.1 million.

The table below details government funding for research expenditures for the years ended December 31, 2022 and 2023.

(1)     As of December 31, 2023, the amount is mainly composed of (i) the research tax credit calculated and recognized for the 2023 financial year for an amount of €9.8 million compared to €9.2
million  for  the  2022  financial  year  which  is  subtracted  (ii)  a  provision  amounting  to  €0.1  million  following  the  tax  inspection  compared  to  €1.3  million  last  year. As  a  reminder,  the  tax
inspection carried out by the French tax authorities related to the 2018, 2019 and 2020 tax credit calculation and 2019 and 2020 income tax calculation as the prescription period are different.
On February 13, 2024, the Company received from the tax authorities the rectification proposal and adjusted the provision to €0.1 million following the final settlement.

(2)     The company can be eligible to local or European grants dedicated to R&D program.

The research tax credit is calculated as 30% of the amount of research and development expenses, net of grants received, eligible for the research
tax credit for the fiscal year.

Research  and  development  expenses  from  continuing  operations  increased  by  €4.4  million,  or  8.4%,  to  €56.0  million  for  the  year  ended
December 31, 2023, as compared to research and development expenses of €51.7 million for the year ended December 31, 2022. This increase
over  the  period  is  mainly  due  to  an  increase  in  direct  research  and  development  expenses  of  €2.7  million  over  the  period.  Research  and
development expenses represented a total of 75.4% and 69.7% of operating expenses before impairment for years ended December 31, 2023 and
December 31, 2022, respectively. Indirect expenses increased by €1.7 million mainly in personnel expenses and amortization and depreciation.

Direct  research  and  development  expenses  increased  by  €2.7  million,  or  9.8%,  to  €30.2  million  for  the  year  ended  December  31,  2023,  as
compared to direct research and development expenses of €27.5 million for the year ended December 31, 2022. This increase is mainly due to a
€3.2 million increase in expenses related to preclinical development programs relating notably to the ADC field, partly offset by a €0.5 million
decrease in expenses related to the Company's clinical programs. This decrease in clinical programs expenses mainly results from a €0.4 million
decrease in expenses relating to the monalizumab program, a €0.2 million decrease in expenses relating to the avdoralimab program and a €0.2
million  decrease  in  expenses  relating  to  the  lacutamab  program,  partly  offset  by  a  €0.7  million  increase  in  expenses  related  to  the  growth  in
IPH5201 phase 2 trials patient recruitment.

Also, as of December 31, 2023, the collaboration liabilities relating to monalizumab and the agreements signed with AstraZeneca in April 2015,
October  2018  and  September  2020  amounted  to  €52.7  million,  as  compared  to  collaborations  liabilities  of  €63.2  million  as  of  December  31,
2022.  This  decrease  of  €10.5  million  mainly  results  from  (i)  net  repayment  of  €8.4  million  during  year  2023  to  AstraZeneca  linked  to  the
Monalizumab cofinancing program, including phase 3 trial INTERLINK-1 launched in October 2020 and PACIFIC-9 launched in April 2022,
and  (ii)  the  decrease  of  the  collaboration  commitment  ("collaboration  liabilities"  in  the  consolidated  statements  of  financial  position)  for  an
amount of €2.0 million linked to the Euro-dollar parity exchange rate variation.

153

 
 
 
Personnel  and  other  expenses  allocated  to  research  and  development  increased  by  €1.7  million,  or  6.9%,  to  €25.8  million  for  the  year  ended
December  31,  2023,  as  compared  to  an  amount  of  €24.2  million  for  the  year  ended  December  31,  2022. This  increase  is  due  to  the  (i)  €0.7
million  increase  in  staff  costs  allocated  to  research  and  development,  of  which  €0.5  million  in  personnel  expenses  and  €0.2  million  in  share-
based payment expenses, (ii) increase of €1.0 million in depreciation and amortization. The line item is mainly composed of the amortization of
the monalizumab, IPH5201 intangible assets.

As  of  December  31,  2023,  the  Company  had  140  employees,  including  Leadership  Team  members,  in  research  and  development  functions,
compared to 155 as of December 31, 2022.

General and administrative expenses

General  and  administrative  expenses  from  continuing  operations  decreased  by  €4.1  million,  or  18.5%,  to  €18.3  million  for  the  year  ended
December 31, 2023, as compared to €22.4 million for the year ended December 31, 2022. General and administrative expenses represented a
total of 24.6% and 30.3% of our total operating expenses before impairment for the years ended December 31, 2023 and 2022, respectively.

(1) Other  expenses  are  related  to  intellectual  property,  maintenance  costs  for  laboratory  equipment  and  our  headquarters,  depreciation  and  amortization  and  other  general  and  administrative

expenses.

Personnel  expenses,  which  includes  the  compensation  paid  to  our  employees  and  consultants,  decreased  by  €1.4  million,  or  13.6%,  to  €8.8
million for the year ended December 31, 2023, as compared to personnel expenses of €10.2 million for the year ended December 31, 2022. This
decrease mainly results from a decrease in wages of €1.2 million as well as a decrease of €0.2 million in share-based payment expenses mainly
explained by the decrease of employees. As of December 31, 2023, we had 39 employees, including Leadership Team members, in general and
administrative functions, as compared to 55 as of December 31, 2022.

Non-scientific advisory and consulting expenses mostly consist of auditing, accounting, legal and hiring services. These expenses decreased by
€1.3 million, or 31.5%, to €2.9 million for the year ended December 31, 2023, as compared to an amount of €4.2 million for the year ended
December 31, 2022. This decrease mainly results from operating efficiency measures, which led to a reduction in the number of new hires, and
use of external communication and consulting services.

154

 
 
 
Other  general  and  administrative  expenses  relate  to  intellectual  property,  depreciation  and  amortization  and  other  general,  administrative
expenses. These expenses decreased by €1.4 million or 17.9% to €6.5 million for the year ended December 31, 2023, as compared to an amount
of €8.0 million for the year ended December 31, 2022.

This  decrease  related  notably  to  savings  (reduction  in  office  space)  and  a  reclassification  of  R&D  laboratory  support  costs  (maintenance,
supplies, depreciation of R&D equipment) for 1.0 million euros in R&D.

Impairment of intangible assets

As a reminder, for the year ended December 31, 2022, impairment of intangible assets results from full impairment of anti-C5aR rights acquired
from  Novo/Nordisk A/S  (avdoralimab  intangible  asset)  for  an  amount  of  €41.0  million.  During  the  fourth  quarter  of  2022,  the  Company  was
informed  by  the  sponsor  of  the  Phase  2  clinical  trial  evaluating  avdoralimab  in  inflammation  in  bullous  pemphigoid  ("BP")  indication  of  its
decision to stop said trial. Consequently, the Company decided in December 2022 to stop the development of avdoralimab in BP indication in
inflammation,  only  indication  supporting  the  recoverable  amount  of  the  asset  as  of  December  31,  2021  (as  well  that  as  of  June  30,  2022).
Without any new event during year ended December 31, 2023, the impairment has not been reassessed.

Financial income (loss), net

The net financial result increased by €5.6 million, to a €5.1 million profit for the year ended December 31, 2023, as compared to a €0.5 million
loss for the year ended December 31, 2022. This change mainly results from interest income on financial investments (net gain of €2.5 million in
2023), the change in the fair value of certain financial instruments (net gain of €1.6 million in 2023 as compared to a net loss of €1.6 million in
2022) and a net foreign exchange gain of €0.9 million in 2023 as compared to a net foreign exchange gain of €0.8 million in 2022.

Net result from discontinued operations

Subsequently  to  the  Termination  and  Transition  Agreement,  operations  related  to  Lumoxiti  are  presented  as  a  discontinued  operation  as  of
October 1, 2021.

As a consequence, the Lumoxiti activity (including sales) is presented in the consolidated income statement and the notes to the consolidated
financial  statements  as  a  discontinued  operation  for  the  2021  financial  year  in  accordance  with  IFRS5  "non-current  assets  held  for  sale  and
discontinued operations."

Thus, the net result from discontinued operations relating to Lumoxiti represents a net loss of €0.1 million as compared to a net loss nil for the
years ended December 31, 2022 and 2023, respectively, presented as follows :

Critical Accounting Policies and Significant Judgments and Estimates

The Company's consolidated financial statements are prepared in accordance with IFRS. Some of the accounting methods and policies used in
preparing the financial statements under IFRS are based on complex and subjective assessments by our management or on estimates based on
past  experience  and  assumptions  deemed  realistic  and  reasonable  based  on  the  facts  and  circumstances.  The  actual  value  of  the  Company's
assets,  liabilities  and  shareholders’  equity,  as  well  as  its  income  and  expenses,  could  differ  from  the  value  derived  from  these  estimates  if
conditions changed and these changes had an impact on the assumptions adopted. See Note 2 to the Company's consolidated financial statements
included under "Item 18. Financial Statements" of this Annual Report.

The  Company  believes  that  the  most  significant  management  judgments  and  assumptions  in  the  preparation  of  its  consolidated  financial
statements are described below.

Accounting for collaboration and licensing arrangements

To  date,  the  Company's  revenue  has  been  generated  primarily  from  payments  received  in  relation  to  research,  collaboration  and  licensing
agreements  signed  with  pharmaceutical  companies.  These  contracts  generally  provide  for  components  such  as  upfront  payments,  milestone
payments upon reaching certain predetermined development objectives, research and development funding, as well as payment of royalties on
future sales of products.

Non-refundable upfront payments are deferred and recognized as revenue over the period Innate is engaged to deliver services to the third party.
Revenue is recognized based on completion of the underlying work.

Milestone payments represent amounts received from Innate's collaborators, the receipt of which is dependent upon the achievement of certain
scientific, regulatory, or commercial milestones. The Company recognizes milestone payments when the triggering event has occurred, there are
no further contingencies or services to be provided with respect to that event, and the counterparty has no right to a refund of the payment. The
triggering event may be scientific results achieved by the Company or another party to the arrangement, regulatory approvals, or the marketing
of products developed under the arrangement. As of December 31, 2024, given the significant progress of the work to be performed (99.92%)
and the level of budget consumption, the impact of accounting estimates is no longer a determining factor in the calculation of revenue related to
the monalizumab agreement.

Estimate of the recoverable amount of the acquired and under progress licenses

Impairment tests are performed on a yearly basis for the intangible assets which are not amortized (such as intangible assets in progress). The
Company is testing amortizable intangible assets for impairment when there is an indicator of impairment. Impairment tests involve comparing
the recoverable amount of the licenses to their net book value. The recoverable amount of an asset is the higher of its fair value less costs to sell
and its value in use. If the carrying amount of any asset is above its recoverable amount, the Company recognizes an impairment loss to reduce
the carrying amount to the recoverable amount. The main assumptions used for the impairment test include (a) the amount of cash flows that are
set  on  the  basis  of  the  development  and  commercialization  plans  and  budgets  approved  by  management,  (b)  assumptions  related  to  the
achievement  of  the  clinical  trials  and  the  launch  of  the  commercialization,  (c)  the  discount  rate,  (d)  assumptions  on  risk  related  to  the
development and (e) for the commercialization, selling price and volume of sales, and are provided in Note 6 to the Company's consolidated
financial statements included under "Item 18. Financial Statements" of this Annual Report. Any change in these

157

assumptions could lead to the recognition of an impairment charge that could have a significant impact on the Company's consolidated financial
statements. In case of failure of the clinical trials in progress, the Company may have to fully depreciate the intangible asset. As of December 31,
2022, given the Company's decision in December 2022 to discontinue the development of avdoralimab in the indication of BP supporting the
recoverable amount of the asset as of December 31, 2021 and June 30, 2022, the rights related to the intangible asset have been fully impaired
for the net carrying amount of the intangible asset, of €41,000 thousand, without using the historical assumptions described above (see Note 6 to
the Company's consolidated financial statements which are included elsewhere in this Annual Report). As a result, the Company considers that
there are no longer any critical estimates in line with intangible assets since 2022. Without any new event to be considered since then, there are
therefore no longer any critical assumptions that could call into question the recoverable amount of the asset.

B.    Liquidity and Capital Resources

The  liquidity  and  capital  resources  discussion  that  follows  contains  certain  estimates  as  of  the  date  of  this Annual  Report  of  the  Company's
estimated  future  sources  and  uses  of  liquidity  (including  estimated  future  capital  resources  and  capital  expenditures)  and  future  financial  and
operating  results.  These  estimates  reflect  numerous  assumptions  made  by  Innate  with  respect  to  industry  performance,  general  business,
economic, regulatory, market and financial conditions and other future events, and matters specific to its businesses, all of which are difficult or
impossible to predict and many of which are beyond its control.

Sources and uses of liquidity

As of December 31, 2024, the Company has primarily financed its operations through its receipt of $656.1 million (€579.1 million) in payments
from its collaborators, including AstraZeneca and Sanofi, since 2011, excluding payments received for purchases of Innate's equity securities by
its collaborators.

Innate has also financed its operations since its inception through several rounds of public and private financings. Since its inception, Innate has
raised a total of €314.3 million through the sale of equity securities, including €33.7 million in the initial public offering of Innate's ordinary
shares on Euronext Paris in 2006 and €66.0 million in the initial public offering of the Company's initial public offering of its ordinary shares on
Nasdaq in 2019 and €5.0 million from Novo Nordisk related to NKG2A agreement.

In addition, Innate has received an aggregate of €109.4 million in French research tax credit ("CIR") through December 31, 2024. As a French
biopharmaceutical company, Innate Pharma has benefited from certain tax advantages, including, for example, the CIR. The research tax credit
can be offset against French corporate income tax due and the portion in excess, if any, may be refunded. The research tax credit is calculated
based  on  Innate's  claimed  amount  of  eligible  research  and  development  expenditures  in  France.  The  research  tax  credit  decreased  by  €2.3
million, or 23%, to €7.5 million for the year ended December 31, 2024, as compared to a research tax credit of €9.7 million for the year ended
December 31, 2023.

Companies  benefiting  from  the  status  of  Community  SMEs  can  request  the  early  reimbursement  of  the  research  tax  credit  starting  from  the
following fiscal year. Innate lost its status as a small or medium size business at the end of the year ended December 31, 2019 and, therefore, was
no  longer  entitled  to  the  immediate  reimbursement  of  the  research  tax  credit  for  the  fiscal  year  ended  2019  and  2020  but  instead  will  be
reimbursed within the expiry of a three-year period. The 2019 and 2020 tax credit was refunded on February 2024 and July 2024 respectively.
For the 2021 and 2022 financial year, the Company again met the criteria of an SME according to the criteria of the European Union. As a result,
the Company was eligible for the early repayment by the French treasury of the 2021 CIR during the fiscal year 2022. As of

158

December  31,  2024,  the  Company  received  reimbursement  for  its  the  CIR  up  to  that  of  the  financial  year  ending  December  31,  2022.  The
Company has been eligible for the early repayment by the French treasury of the 2022 CIR during the fiscal year 2023. As of the end of the
financial year ending December, 31 2023, the Company again lost SME status. As a consequence, the 2023 and 2024 CIR amounts are expected
to be paid after a three-year period. The CIR due to the Company for the financial year ending December 31, 2023 is refundable by the French
tax administration by December 31, 2027, and was recorded as a long-term receivable for the financial year ending December 31, 2023.

Pursuant to an agreement with Natixis dated December 10, 2024 regarding financing of the CIR and pursuant to a French-law assignment of the
CIR  receivable  to  Natixis,  Natixis  paid  to  the  Company  €8.6  million  in  December  2024  relating  to  the  CIR  credit  for  financial  year  ending
December 31, 2023, corresponding to 95% of the CIR refund from the financial year 2023 in December 2024. Natixis will pay to the Company
the remaining five percent of the CIR refund regarding the 2023 financial year at the end of a three-year period, i.e., in 2027, subject to the CIR
refund  amount  for  the  financial  year  ending  December  31,  2023  being  modified  or  reclaimed  by  the  French  Tax  authority.  The  Company
recognized this amount as "Other non-current assets".

Innate  is  potentially  eligible  to  earn  milestone  payments  and  royalties  under  its  agreements  with AstraZeneca  in  the  event  that  the  Company
satisfies  certain  pre-specified  milestones.  Innate  may  enter  into  new  collaboration  agreements  that  also  provide  milestone  payments.  These
milestone  payments  are  dependent  on  the  accomplishment  of  various  development,  regulatory  and  commercialization  objectives,  and  the
achievement of many of these milestones is outside of Innate's control. However, Innate's ability to earn these payments and their timing will, in
part, be dependent upon the outcome of its research activities, which is uncertain at this time.

On July 3, 2017, Innate Pharma borrowed from the bank Société Générale in order to finance the construction of its future headquarters. This
loan, amounting to a maximum of €15.2 million, can be drawn down during the period of the construction in order to pay supplier payments as
they become due, but in any event no later than August 30, 2019. Given the development of its portfolio, and in particular the refocusing of its
activities  on  research  and  development,  the  Company  has  for  the  time  being  suspended  the  project  to  build  its  new  head  office  on  the  land
acquired  in  Luminy.  In  the  meantime,  the  loan  will  be  used  to  finance  several  structuring  projects  (improvement  of  the  information  system,
development of a commercial platform, development of additional premises rented, etc.). Repayment of any amounts drawn down are payable
over a 12-year term beginning on August 30, 2019 and ending on August 30, 2031. As security for the loan, Innate pledged collateral in the form
of financial instruments held at Société Générale amounting to €15.2 million. The security interest on the pledged financial instruments will be
released in accordance with the following schedule: €4.2 million in July 2024, €5.0 million in August 2027 and €6.0 million in August 2031. The
Company had drawn down €15.2 million under the loan as of December 31, 2019. The loan bears a fixed interest rate of 2.01%. Under the loan,
Innate is subject to a covenant that its total cash, cash equivalents and current and non-current financial assets as of each fiscal year end will be at
least equal to the amount of outstanding principal under the loan. As of December 31, 2024, the remaining capital of this loan amounted to €8.9
million as compared to €10.2 million as of December 31, 2023. As expected, the financial investment amounting to €4.2 million was released on
July 2024.

On January 5, 2022, the Company announced that it had obtained non-dilutive financing of €28.7 million in the form of two State-Guaranteed
Loans (Prêts Garantis “PGE”) from Société Générale (€20.0 million) and BNP Paribas (€8.7 million). The funds related to these two PGEs were
collected by the Company on December 27 and 30, 2021, respectively. These two loans have an initial maturity of one year, with an option to
extend up to five years from August 2022. They are 90% guaranteed by the French State as part of a system put in place to support companies in
the face of the COVID-19 health crisis. In

159

August  2022,  the  Company  requested  the  extension  of  these  two  loans  repayment  for  an  additional  period  of  five  years  starting  in  2022  and
including a one-year grace period (2023). Consequently, the Company has obtained agreements from Société Générale and BNP Paribas. The
effective interest rates applied to these contracts during the additional period are 1.56% and 0.95% for Société Générale and BNP Paribas loans,
respectively,  excluding  insurance  and  guarantee  fees,  with  an  amortization  exemption  for  the  entire  year  2023.  During  this  grace  period,  the
Company was only liable for the payment of interest and the guarantee fees, with amortization of the two loans starting in 2024 over a period of
four years. The state guarantee fees amount to €877 thousand and €379 thousand for Société Générale and BNP Paribas loans respectively. As of
December 31, 2024, the remaining capital of these loans amounted to €21.7 million.

On April 24, 2025, the Company announced that, given the satisfactory market conditions, Sanofi subscribed to 8,345,387 new ordinary shares
of  Innate,  at  a  price  of  €1.7974  per  share,  representing  a  total  capital  increase  of  €14,999,998.59  (€417,269.35  in  nominal  amount  and
€14,582,729.24 of issue premium). The newly issued shares were admitted to trading on the regulated market of Euronext in Paris on the same
day. See Note 21 to the consolidated financial statements included under "Item 18. Financial Statements" of this Annual Report.

Lastly,  during  the  years  ended  December  31,  2016  and  2017,  Innate  also  used  lease-financing  and  bank  loans  to  finance  the  acquisition  of
laboratory equipment and to set up new laboratories. The debt related to these loans amounts to €42,000 at December 31, 2024.

Cash, cash equivalents and short-term investments decreased by €11.7 million, or 13%, to €80.8 million as of December 31, 2024, as compared
to cash, cash equivalents and short-term investments of €92.5 million as of December 31, 2023. Net cash as of December 31, 2024 amounted to
€72.1  million  (€83.5  million  as  of  December  31,  2023).  Net  cash  is  equal  to  cash,  cash  equivalents  and  short-term  investments  less  current
financial liabilities. Net cash is a non-IFRS financial indicator that is reviewed by the Company’s management and that the Company believes
provides  useful  information  to  investors  with  respect  to  measuring  cash  resources  that  are  available  for  strategic  investment.  Net  cash  is  not
defined by IFRS and is not a substitute for “cash and cash equivalents” as reported under IFRS. The term net cash may be interpreted differently
by  other  companies  and  under  different  circumstances.  Cash  and  cash  equivalents  are  mainly  composed  of  current  bank  accounts,  interest-
bearing  accounts,  fixed-term  accounts  and  money  market  funds  as  per AMF  definition.  Short-term  investments  primarily  consist  of  shares  of
mutual funds and all investments with a maturity less than one year. Their purpose is to finance Innate's activities, including Innate's research and
development costs.

As a reminder, Innate has received a total of €309.3 million in cash from capital increases, before deducting the costs associated with capital
increases,  and  after  excluding  proceeds  from  share  compensation  instruments,  between  1999  and  December  31,  2019.  The  table  below

The Company's net cash flow used in operating activities decreased by €25.7 million to €6.9 million for the year ended December 31, 2024 as
compared to net cash flows used in operating activities of €32.6 million for the year ended December 31, 2023.

This variation is mainly due to (i) the receipt of €29.5 million related to 2019 and 2020 tax credit refunds, (ii) the receipt of €8.6 million pursuant
to a financing agreement with Natixis including the assignment of the Company's receive with respect to future CIR payments (corresponding to
the CIR for the financial year ending December 31, 2023 that will be paid in 2027), (iii) the receipt of €15.0 millions in January

162

 
 
 
2024 following Sanofi's decision to exercise one of its two license option for an NK Cell Engager program in solid tumors, derived from the
Company's ANKET® (Antibody-based NK Cell Engager Therapeutics) platform, pursuant to the terms of the research collaboration and license
agreement signed in December 2022, (iv) the collection in May 2024 of €4.8 million (including value-added tax) the treatment of the first patient
in the Phase 2 dose expansion part of the Sanofi-sponsored clinical trial evaluating NK Cell Engager SAR443579/ IPH6101 in various blood
cancer.

As  a  reminder,  in  2023,  the  net  cash  flow  used  in  operating  activities  included  (i)  the  receipt  of  €25.0  million  from  Sanofi  in  March  2023
following the entry into force of the research collaboration and licensing agreement signed in December 2022 under which the Company granted
Genzyme Corporation, a wholly-owned subsidiary of Sanofi ("Sanofi") an exclusive licence to Innate Pharma's B7H3 ANKET  program and
options on two additional targets, (ii) the receipt in May 2023 of a payment of €4.6 million ($5.0 million) received from Takeda following the
conclusion of an exclusive licensing agreement under which Innate granted Takeda exclusive worldwide rights for the research and development
of ADCs,  (iii)  the  receipt  in  July  2023  of  €2.0  million  following  the  treatment  of  the  first  patient  in  the  Phase  1/2  clinical  trial  sponsored  by
Sanofi evaluating IPH6401/SAR'514 in patients with relapsed or refractory multiple myeloma. Lastly, during 2023, the Company benefited from
the early repayment of the CIR claim relating to the 2022 financial year, amounting to €9.2 million, paid to the Company by the French Treasury
in July 2023.

®

Excluding these specific effects, net cash flows used by operating activities for the year ended December 31, 2024 decreased by €9.4 million.
This decrease is mainly explained by (i) the decrease in the operating expenses.

Cash flows from / (used in) investing activities

The Company's net cash flows from investing activities for the year ended December 31, 2024 amounted to €9.2 million and mainly included a
€4.2 million of current financial instrument with a July 2024 fixed term and various non current financial assets sales for a total of €5.0 million
to cope with Company dollars cash needs. These cash in were partially offset by acquisitions of property, plant and equipment and intangible
assets for a net amount €0.4 million. As a reminder, net cash flow used in investing activities for the year ended December 31, 2023 amounted to
€20.6  million  and  were  mainly  composed  of  a  disposal  of  a  non-current  financial  instrument  which  generated  a  net  cash  collection  of  €22.8
million partially offset by acquisitions of property, plant and equipment and intangible assets for a net amount €2.2 million.

Cash flows from / (used in) financing activities

The Company's net cash flows used in financing activities for the year ended December 31, 2024 increased by €4.0 million to €6.0 million for
the  year  ended  December  31,  2024  as  compared  to  net  cash  flows  from  financing  activities  of  €2.0  million  for  the  year  ended  December  31,
2023.

Loan repayments amounted to €8.9 million for the year ended December 31, 2024 as compared to €2.4 million for the year ended December 31,
2023. The start of PGE loans repayment in 2024 result in an increase in repayment amounting to €7.0 million.

Receipts from capital transactions amount to €2.9 million in 2024, compared with €0.4 million in 2023. The change is mainly explained by the
amount received from a new equity partner for €2.9 million.

compared to net cash flows used in operating activities of €19.2 million for the year ended December 31, 2022. This variation is mainly due to
(i) the receipt of €25.0 million from Sanofi in March 2023 following the entry into force of the research collaboration and licensing agreement
signed  in  December  2022  under  which  the  Company  granted  Genzyme  Corporation,  a  wholly-owned  subsidiary  of  Sanofi  ("Sanofi")  an
exclusive licence to Innate Pharma's B7H3 ANKET  program and options on two additional targets, (ii) the receipt in May 2023 of a payment of
€4.6  million  ($5.0  million)  received  from  Takeda  following  the  conclusion  of  an  exclusive  licensing  agreement  under  which  Innate  granted
Takeda  exclusive  worldwide  rights  for  the  research  and  development  of  ADCs,  (iii)  the  receipt  in  July  2023  of  €2.0  million  following  the
treatment  of  the  first  patient  in  the  Phase  1/2  clinical  trial  sponsored  by  Sanofi  evaluating  IPH6401/SAR'514  in  patients  with  relapsed  or
refractory multiple myeloma. Lastly, during 2023, the Company benefited from the early repayment of the research tax credit claim relating to
the 2022 financial year, amounting to €9.2 million, paid to the Company by the French Treasury in July 2023. As a reminder, cash flows used in
operating  activities  for  the  year  ended  December  31,  2022,  included  successive  (i)  the  collection  of  €47.7  million  ($50.0  million)  and  €4.9
million  ($5.0  million)  in  June  2022  and  August  2022,respectively,  under  the  monalizumab  agreement  and  the  amendment  to  the  IPH5201
collaboration and option agreement, (ii) the collection of €3.0 million received from Sanofi under the 2016 agreement and following Sanofi's
decision  to  advance  IPH6401/SAR'514  into  regulatory  preclinical  studies  for  an  investigational  new  drug,  and  (iii)  in  2022,  the  Company
collected the early repayment of the research tax credit receivable relating to the 2021 financial year for an amount of €10.3 million, paid to the
Company  by  the  French Treasury  in  November  2022. These  collections  were  partially  offset  by  the  €5.9  million  payment  to AstraZeneca  on
April  20,  2022  pursuant  to  the  Termination  and  Transition Agreement  and  cash  outflows  related  to  the  Company's  operating  activities.  Not
considering these specific effects, net cash flows used by operating activities for the year ended December 31, 2023 decreased by €5.5 million.
This decrease is mainly explained by the decrease in the Company's research and development activities, notably related to preclinical trials, and
also by higher cash outflows related to the re-invoicing of costs to AstraZeneca for the Phase 3 trials evaluating monalizumab, INTERLINK-1
and PACIFIC-9, in accordance with the Company's co-financing commitments and the reduction in staff costs related to the reduction of staff in
the Company.

Net cash flow consumed by operating activities in connection with the Lumoxiti discontinued operation are nil for the year ended December 31,
2023 as compared to € 5.1 million for the year 2022. In 2022, the cash consumption related to the payment to AstraZeneca of €5.9 million in
April 2022 under the Termination and Transition Agreement.

Cash flows from / (used in) investing activities

The  Company's  net  cash  flows  from  investing  activities  for  the  year  ended  December  31,  2023  amounted  to  €20.6  million  and  are  mainly
composed  of  a  disposal  of  a  non-current  financial  instrument  which  generated  a  net  cash  collection  of  €22.8  million  partially  offset  by
acquisitions of property, plant and equipment and intangible assets for a net amount €2.2 million. As a reminder, net cash flow used in investing
activities for the year ended December 31, 2022 amounted to €1.9 million and were mainly comprised of acquisitions of tangibles assets and
disposal of a current financial instrument liquidation for €3.0 million.

Net cash flows consumed by investing activities in connection with the Lumoxiti discontinued operation were nil for the year ended December
31, 2023 and 2022, respectively.

Cash flows from / (used in) financing activities

The Company's net cash flows used in financing activities for the year ended December 31, 2023 increased by €0.1 million to €2.0 million for
the  year  ended  December  31,  2023  as  compared  to  net  cash  flows  from  financing  activities  of  €1.8  million  for  the  year  ended  December  31,
2022.

Loan repayments amounted to €2.4 million for the year ended December 31, 2023 as compared to €2.0 million for the year ended December 31,
2022.

In addition, net cash flows from financing activities related to Lumoxiti discontinued operations are nil for the year ended December 31, 2022
and 2021, respectively.

Funding requirements

Innate Pharma believes that its existing cash, cash equivalents, short-term investments and non-current financial assets, will enable it to fund its
operations for at least the next 12 months. Innate has based this estimate on assumptions that may prove to be wrong, and the Company could
use its capital resources sooner than it currently expects.

Until Innate can generate a sufficient amount of revenue from the sale of approved products, if ever, it expects to finance its operating activities
through its existing liquidity and expected milestone payments from collaborators.

Innate's present and future funding requirements will depend on many factors, including, among other things:

•

•

•

•

•

the  size,  progress,  timing  and  completion  of  its  clinical  trials  and  preclinical  studies  for  any  current  or  future  product  candidates,
including its lead product candidates, monalizumab and lacutamab;

the number of potential new product candidates Innate identifies and decides to develop;

costs associated with its payment obligations to third parties in connection with its development and potential commercialization of
certain of its product candidates;

costs associated with expanding its organization;

the  costs  involved  in  filing  patent  applications  and  maintaining  and  enforcing  patents  or  defending  against  claims  of  infringement
raised by third parties;

165

•

•

the time and costs involved in obtaining regulatory approval for its product candidates and any delays the Company may encounter as
a result of evolving regulatory requirements or adverse results with respect to any of these product candidates;

the amount of revenues, if any, Innate Pharma may derive either directly, or in the form of milestone or royalty payments from any
future  potential  partnership  agreements,  from  monalizumab,  IPH5201,  IPH6101/SAR443579,  IPH6401/SAR'514,  B7H3  or  other
target or relating to its other product candidates.

For  more  information  as  to  the  risks  associated  with  Innate's  future  funding  needs,  see  “Risk  Factors—The  Company  may  need  to  raise
additional funding to complete the development and any commercialization of its product candidates, which may not be available on acceptable
terms,  or  at  all,  and  failure  to  obtain  this  necessary  capital  when  needed  may  force  the  Company  to  delay,  limit  or  terminate  its  product
development efforts or other operations.”

Capital expenditures

Innate Pharma's operations mainly require investment in intangible assets. Innate acquired the rights of avdoralimab from Novo Nordisk A/S in
2017. The Company paid an upfront fee of €40.0 million, of which €37.2 million was contributed in new ordinary shares and €2.8 million in
cash. As part of this agreement, an additional amount of € 1.0 million was paid in October 2020 to Novo Nordisk A / S following the launch of
the first avdoralimab Phase 2 trial.

In January 2019, Innate Pharma paid to AstraZeneca an initial payment for the license related to Lumoxiti ($50.0 million, or €43.8 million, using
the foreign exchange rate of 1.1422 at the date of payment), and in February 2019, Innate paid to Novo Nordisk A/S additional consideration
relating to monalizumab ($15.0 million, or €13.1 million, using the exchange rate of 1.1394 at the date of payment). In June 2019, Innate paid
€7.0 million to Orega Biotech in relation to the anti-CD39 program as consideration and will be required to pay a low-teen percentage to Orega
Biotech on a going forward basis of sub-licensing revenues received pursuant to the 2018 AZ Option Agreement, up to an additional amount of
up to €47 million. See Note 6 to the consolidated financial statements included as part of this Annual Report.

Innate's operations generally require little investment in tangible assets because the Company outsources most of the manufacturing and research
activities  to  third  parties.  Innate  Pharma  leases  some  of  its  computer  equipment  under  operating  lease  agreements.  Innate  accounts  for  its
payments for these items as operating expenses in the consolidated statement of income.

The Company's capital expenditures in the years ended December 31, 2022, 2023 and 2024 primarily related to laboratory equipment. Clinical
research and development costs are not capitalized until marketing authorizations are obtained.

Innate's corporate office in Luminy, Marseille, France is leased under a finance lease agreement signed in 2008 with Sogebail, a subsidiary of
Société Générale, for an aggregate amount of €6.6 million. The lease-financing agreement has a 12-year term. Innate has a purchase option for
all of the buildings and land for the lump sum of €1 at the end of the term of the contract on June 9, 2020, which it has exercised. The Company
now owns its corporate office in Luminy, Marseille.

Since July 2017, Innate also rents office space in Marseille, France under a commercial lease.

On  January  10,  2020,  the  Company  signed  an  amendment  to  the  lease  for  the  “Le  Virage”  building  in  order  to  expand  its  premises.  This
amendment also extended the duration of the contractual commitment until 2025.

On March 13, 2023, the Company signed an amendment to the lease for "Le Virage Building" in order to reduce the rental area of its premises
located in the "Le Virage" building. This amendment has the effect

166

of reducing the amount of the commitment relating to rent by €685 thousand. The Company remains committed under this contract until June 30,
2025.

Family Relationships

Company referred to above.

Arrangements with existing Major Shareholders and Customers

There are no arrangements with major shareholders, customers, suppliers or others, pursuant to which any person referred to above was selected

Subsequent Developments

The Company plans to ask to the next General Meeting to be held on May 22, 2025 to approve its transformation into a société anonyme with a
Board of Directors ("conseil d'administration"). This transformation is part of a strategic move to simplify and align Innate Pharma's corporate
governance with international standards.

If the General Meeting approves this governance change, it will be asked to appoint as members to the Board of Directors, Irina Staatz-Granzer,
Pascale Boissel, Sally Bennett, Véronique Chabernaud, Bpifrance (represented by Olivier Martinez), Jonathan Dickinson and two new members
of  the  Board  of  Directors,  Marty  J.  Duvall  and  Christian  Itin.  If  the  General  Meeting  approves  this  change  in  governance  and  the  proposed
composition  of  the  Board  of  Directors,  the  Board  of  Directors  is  expected  to  appoint  Irina  Staatz-Granzer  as  its  Chairwoman  and  Jonathan
Dickinson as Chief Executive Officer at its first meeting after the General Meeting.

If shareholders do not approve the governance change, it would be proposed to renew the mandate of the current members of the Supervisory
Board whose terms of office are due to expire – with the exception of Gilles Brisson and Jean-Yves Blay – and to appoint two new members,
Marty  J.  Duvall  and  Christian  Itin.  The  composition  of  the  Executive  Board  would  remain  unchanged,  as  Jonathan  Dickinson  would  remain
Chairman and Yannis Morel and Sonia Quaratino would remain members (Arvind Sood resigned from his position on the Executive Board in
February 2025).

Mr.  Marty  J.  Duvall  is  a  biotechnology  executive  based  in  the  United  States,  with  over  35  years  of  experience  building  companies  in  the
pharmaceutical and biotechnology industry, focused in specialty therapeutics. Mr. Duvall’s main pharma experience includes global oncology
leadership positions at Aventis and Merck. His biotech experience includes leading to strategic transactions at MGI Pharma, Abraxis Bioscience,

Compensation of Members of the Executive Board

Breakdown of the Executive Board Members' Compensation

During  the  year  ended  on  December  31,  2024,  the  Executive  Board  consisted  of  Hervé  Brailly,  Jonathan  Dickinson,  Yannis  Morel,  Sonia
Quaratino and Arvind Sood. Hervé Brailly served as interim CEO and Chairman of the Executive Board from January 1, 2024 to October 31,
2024. He was replaced by Jonathan Dickinson as CEO and Chairman of the Executive Board effective November 1, 2024. Arvind Sood resigned
from his mandate of member of the Executive Board on February 3, 2025.

The compensation of members of the Executive Board is decided by the Supervisory Board upon recommendation by the Compensation and
Nomination Committee. The compensation of Hervé Brailly and Jonathan Dickinson as Chairman of the Executive Board, is paid under their
social mandate (mandat social), whereas the compensation of Yannis Morel, Sonia Quaratino and Arvind Sood is paid under their employment
contract.

The compensation of members of the Executive Board includes the following components:

•

•

Fixed Compensation. The members of the Executive Board receive a fixed compensation pursuant to their employment agreements or, in
the case of the Chairman, his social mandate (mandat social).

Annual  Variable  Compensation.  The  members  of  the  Executive  Board  are  eligible  to  receive  annual  variable  compensation  upon  the
recommendation  of  the  Compensation  and  Nomination  Committee  based  on  the  achievement  of  pre-specified  objectives.  For  the  year
ended on December 31, 2024,

176

such objectives were based on the achievement of the Company's main strategic pillars and operational targets defined according to Innate
Pharma's activities in order to (i) take into account the outperformance inherent to a fast-growing biotech company and (ii) motivate the
executives to exceed their objectives.

The  strategic  pillars  are  the  following:  (i)  partnering  Lacutamab,  (ii)  completing  IPH6501  dose  level  3,  (iii)  IND  filing  by  3Q2024  for
IPH4502, complemented by two other pillars: (iv) finance and (v) corporate.

Each pillar was subdivided into:

(i) core objectives; and

(ii) outperformance targets.

The weights of each pillar are as follows:

If 100% of the core objectives are achieved, 100% of the corresponding bonus is paid. If not 100% of the core objectives is achieved, the
percentage of the bonus paid is proportional to the percentage of achievement of the core objectives. In case of outperformance for the year
2024, it may be decided to increase the amount of the bonus beyond 100% up to a limit of 150% based on other predefined criteria.

The outperformance targets may only be reached if 100% of the core objectives are reached.

•

•

Performance Free Shares. The members of the Executive Board are able to receive, upon authorization of the Supervisory Board and upon
recommendation of the Compensation and Nomination Committee, equity compensation in the form of performance free shares.

Other Benefits. The members of the Executive Board may also receive other benefits consisting of a supplementary pension plan, in-kind
benefits and, for the Chairman of the Executive Board, an unemployment insurance.

Executive Compensation Clawback Policy

Pursuant to the rules adopted by the SEC pursuant to Section 10D-1 of the Exchange Act, requiring national securities exchanges and national
securities associations, such as the NYSE, to amend their relevant listing standards no later than November 28, 2023 to require companies with
listed  securities  to  put  in  place  a  policy  whereby  listed  companies  will  recover  erroneously-awarded  variable  compensation  from  the  Chief
Executive  Officer  and  certain  other  “executive  officers”  as  defined  in  Rule  10D-1(d)  under  the  Exchange  Act.  On  June  9,  2023,  the  SEC
approved the Nasdaq’s proposed rule amending its listing standards for recovery of erroneously awarded compensation by listed issuers, which
has taken effect on October 2, 2023.

On  October  13,  2023,  the  Supervisory  Board  approved  the  adoption  of  a  clawback  policy,  applicable  from  October  2,  2023,  requiring  the
recovery  in  full  or  in  part  of  the  components  of  the  Chief  Executive  Officer's  compensation  that  are  wholly  or  partially  contingent  on  the
attainment  of  financial  performance  criteria  based  on  financial  information  that  has  been  determined  to  be  erroneous  and  has  required
restatement of the financial statements for accounting purposes.

(1) Jonathan Dickinson was not eligible for the Annual Variable Compensation for the year ended on December 31, 2024.

181

The variable compensation for the year ending on December 31, 2025 is based on the achievement of the Company's main strategic pillars and
operational targets defined according to Innate Pharma's activities in order to (i) take into account the outperformance inherent to a fast-growing
biotech company and (ii) motivate the managers to exceed their objectives.

There are five pillars which are essential to the achievement of the strategic axes mentioned above.

Each pillar has been subdivided into:

(i) core objectives; and

(ii) outperformance targets.

The weights of each pillar are:

Core objectives

The annual objectives thus defined make it possible to reward the Company's expected performance but also to assess outperformance.

If 100% of the basic core objectives are achieved, 100% of the corresponding bonus is paid. If not 100% of the core objectives are achieved, the
percentage  of  the  bonus  paid  is  proportional  to  the  percentage  of  achievement  of  the  core  objectives.  In  case  of  outperformance  for  the  year
2025, the amount of the bonus may be increased beyond 100% up to a limit of 150% based on other predefined criteria.

The outperformance targets may only be reached if 100% of the core objectives are reached.

At the General Meeting to be held on May 22, 2025, the allocation of free performance shares subject to capitalization evolution and internal
conditions as well as the allocation of free shares subject to specific performance criteria will be put to the vote of its shareholders.

Limitations on Liability and Indemnification Matters

Under French law, provisions of bylaws that limit the liability of the members of Executive and Supervisory Boards are prohibited. However,
French law allows sociétés anonymes to contract for and maintain liability insurance against civil liabilities incurred by members of Executive
and Supervisory Boards involved in a third-party action, provided that they acted in good faith and within their capacities as members of such
Boards  of  the  Company.  Criminal  liability  cannot  be  indemnified  under  French  law,  whether  directly  by  the  Company  or  through  liability
insurance.

The  Company  has  a  liability  insurance  for  its  Executive  and  Supervisory  Board  members,  and  insurance  coverage  for  liability  under  the
Securities  Act.  The  Company  also  entered  into  agreements  with  its  Executive  and  Supervisory  Board  members  to  provide  contractual
indemnification.  With  certain  exceptions  and  subject  to  limitations  on  indemnification  under  French  law,  these  agreements  provide  for
indemnification for damages and expenses including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by
any Executive or Supervisory Board member in any action or proceeding arising out of his or her actions in that capacity. The Company believes
that this insurance and these agreements are necessary to attract qualified Executive and Supervisory Board members.

182

These  agreements  may  discourage  shareholders  from  bringing  a  lawsuit  against  the  Executive  and  Supervisory  Board  members  for  breach  of
their  fiduciary  duty.  These  provisions  also  may  have  the  effect  of  reducing  the  likelihood  of  derivative  litigation  against  the  Executive  and
Supervisory Board members, even though such an action, if successful, might otherwise benefit the Company and its shareholders. Furthermore,
a shareholder’s investment may be adversely affected to the extent the Company pays the costs of settlement and damages awards against its
Executive and Supervisory Board members pursuant to these insurance agreements.

Equity Incentives

The  Company  believes  that  the  ability  to  grant  equity  incentives  is  a  valuable  and  necessary  compensation  tool  that  allows  the  Company  to
attract  and  retain  the  best  personnel  for  positions  of  substantial  responsibility,  provides  additional  incentives  to  employees  and  promotes  the
success  of  its  business.  Due  to  French  corporate  law  and  tax  considerations,  the  Company  has  historically  granted  several  different  equity
incentive instruments to its Executive Board and Supervisory Board members, employees and consultants, including (i) warrants (BSAs), which
have historically only been granted to independent members of the Supervisory Board and consultants, (ii) redeemable warrants (BSAARs) and
(iii) free shares.

The Executive Board’s authority to grant these warrants and free shares and the aggregate amount authorized to be granted must be approved by
two-thirds  of  the  shareholders  present  at  the  relevant  extraordinary  shareholders’  meeting.  Once  approved  by  the  shareholders,  the  Executive
Board can continue to grant such awards for a specified period upon prior authorization of the Supervisory Board.

The Company has various compensation plans for its Executive Board members, Supervisory Board members, employees and consultants that
have  been  approved  by  the  shareholders.  The  last  allocation  of  BSAARs  which  occurred  in  2015  no  longer  continues  to  vest  following
termination of the employment, office or service of the holder within the first two years and all vested warrants must be exercised within post-
termination  exercise  periods  set  forth  in  the  issuance  agreement.  In  the  event  of  certain  changes  in  its  share  capital  structure,  such  as  a
consolidation or share split or dividend, French law and applicable issuance agreement provides for appropriate adjustments of the numbers of
ordinary shares issuable and/or the exercise price of the outstanding warrants.

As of December 31, 2024, the Company had the following equity awards, warrants and free shares outstanding:

•

•

•

•

167,460 ordinary shares issuable upon the exercise of 167,460 share warrants (BSA) outstanding as of December 31, 2024 at a weighted
average exercise price of 7,84 € per ordinary share;

Equity Warrants and Redeemable Share Subscription Warrants

Share Warrants (BSA)

Share warrants (BSA) are issued at a de minimis price and entitle the holder of one BSA to exercise the warrant for one underlying share, at an
exercise price per share determined by the Executive Board of the Company at the time of issue by reference to the then prevailing share price.
The  Company  has  issued  BSA  to  Supervisory  Board  members  and  certain  consultants  of  the  Company.  The  Company's  BSA  plans  include
provisions that allow for the adjustment of the one-for-one exercise ratio to compensate for certain modifications of its share capital, such as
rights issues, stock splits, mergers and other events affecting all existing shareholders. None of those events have occurred yet. The Company's
BSA have an exercise period of 10 years – BSA not exercised after that time lapse and are automatically cancelled. The Company's BSA cannot
be sold.

Redeemable Share Warrants (BSAAR)

Redeemable  share  warrants,  or  BSAAR,  are  identical  to  the  share  warrants  of  BSA  (including  the  one-for-one  exercise  ratio,  its  potential
adjustment for certain modifications of the share capital and the exercise period of 10 years), except for the following features:

•

•

the BSAAR are initially purchased by the beneficiary at their fair value, as determined by an expert, and

the  BSAAR  plans  include  a  “forcing”  clause  making  it  possible  to  encourage  holders  to  exercise  their  BSAAR  when  the  market  price
exceeds the exercise price and reaches a threshold defined in the BSAAR issuance agreement. The Company can then, subject to a time
period for notifying the holders that will permit them to exercise their BSAAR, decide to purchase the unexercised BSAAR at a unit price
equal to the BSAAR acquisition price initially paid by their holders.

Innate's redeemable share warrants cannot be sold. The BSAAR have been granted to certain of the executive officers and employees.

Free Shares (AGA)

Free shares (AGA) are employee equity incentive instruments pursuant to which the beneficiaries are granted, for free, the possibility to receive
ordinary shares under certain conditions. Upon grant by the Executive Board of the Company, the AGA are subject to an acquisition, or vesting,
period of at least one year. At the end of this period, the free shares vest and the beneficiary becomes a full shareholder. However, if the vesting
period is less than a certain period set by law (currently two years), it must be followed by a holding period, so that the sum of the vesting period
and the holding period is equal to a minimum total period also set by law (currently two years). Vesting can be conditional or not. The vesting of
all or the Company's AGA is subject to a presence condition at the end of the vesting period. Some of the Company's AGA are also subject to
performance conditions. Over the years, the Company has established several AGA plans, for its employees or for management only, sometimes
as a “welcome package” (with no performance conditions). The Company's free share plans include provisions that allow for the adjustment of
the number of ordinary shares to which a beneficiary is entitled at the end of the vesting period to compensate for certain modifications of its
share capital, such as rights issues, stock splits, mergers and other events affecting all existing shareholders, during the vesting period. Certain of
the Company's plans also provide for an accelerated vesting in case of a tender offer on the Company during the vesting period.

presence  condition  and,  as  applicable,  the  performance  conditions,  have  not  been  met.  For  the  purpose  of  computing  the  amount  of  share-based  compensation  in  its  consolidated  financial
statements, AGA  that  have  lapsed  because  the  presence  condition  has  not  been  met,  are  excluded  from  the  computation,  even  though  the  Executive  Board  has  not  met  yet  and  formally
acknowledged this fact. As a result, certain of the numbers above are different from those in its consolidated financial statements.

Free Preferred Shares (AGAP)

Free preferred shares (AGAP) are another employee equity incentive instrument similar to the free shares or AGA, except that, after a one-year
vesting period, the beneficiaries receive a preferred shares (shares B) which will become convertible into ordinary shares following a lock-up
period  of  two  additional  years,  if  the  performance  conditions  (and  a  presence  condition)  are  met  at  the  end  of  this  lock-up  period.  Each  free
preferred share is convertible into a number of ordinary shares of the Company – which number depends upon the degree of fulfilment of the
performance  conditions.  The  free  preferred  shares  remain  convertible  into  ordinary  shares  for  a  period  of  six  years  and  six  months.  Free
preferred shares not converted at the end of this conversion period can be repurchased by Innate and cancelled. The Company's AGAP cannot be
sold.

The Company has established several AGAP plans in 2016 and 2017 for all of its employees or for management only.

Since the end of the lock-up period, holders of the 2016 AGAP that have not yet converted them into ordinary shares, are entitled to vote at the
shareholders’  meetings,  to  dividends  and  to  preferential  subscription  rights,  on  the  basis  of  the  number  of  ordinary  shares  to  which  they  are
entitled if they convert their AGAP.

On  October  21,  2019,  the  performance  criteria  of  the  2016-1 AGAP  were  assessed  and  the  conversion  ratio  was  determined  as  follows:  one
2016-1 AGAP gives right to 130 ordinary shares.

On December 30, 2019, the performance criteria of the 2016-2 AGAP were assessed and the conversion ratio was determined as follows: one
2016-2 AGAP gives right to 111 ordinary shares.

The 2017 AGAP are not convertible since the performance criteria were not met.

The Supervisory Board is made up of a minimum of three members and a maximum of eighteen. The members of the Supervisory Board are
appointed  for  a  renewable  term  of  two  years  at  the  general  meeting  of  shareholders,  which  may  revoke  their  appointments  at  any  time.  The
appointees are selected from among the shareholders and may be individuals or companies. Each member must own at least one of our ordinary
shares for the entire term of the appointment. Members of the Supervisory Board cannot be members of the Executive Board.

The number of members of the Supervisory Board who have reached the age of seventy years cannot be higher than a third of the members of
the Supervisory Board. If the age limitation is exceeded, the eldest member is deemed to have resigned automatically.

There was no directors' service contracts with the Company or any of its subsidiaries providing for benefits upon termination of employment, for
the Company's last completed fiscal year.

Role of the Supervisory Board in Risk Oversight

The Supervisory Board is primarily responsible for the oversight of the risk management activities and has delegated to the Audit Committee the
responsibility to assist the Supervisory Board in this task. While the Supervisory Board oversees risk management, management, through the
Executive Board is responsible for day-to-day risk management processes. The Supervisory Board expects the management to consider risk and
risk  management  in  each  business  decision,  to  proactively  develop  and  monitor  risk  management  strategies  and  processes  for  day-to-day
activities  and  to  effectively  implement  risk  management  strategies  adopted  by  the  Supervisory  Board. The  Company  believes  this  division  of
responsibilities is the most effective approach for addressing the risks the Company faces.

190

Supervisory Board Committees

The Supervisory Board has established an Audit Committee, a Compensation and Nomination Committee, a Corporate and Social Responsibility

A. Major Shareholders

The  following  table  and  accompanying  footnotes  set  forth,  as  of April  25,  2025,  information  regarding  beneficial  ownership  of  the  ordinary
shares by:

•

•

•

each person, or group of affiliated persons, known by Innate to beneficially own more than 5% of the ordinary shares;

each of the Leadership Team and Supervisory Board members individually; and

all of the Executive Board and Supervisory Board members as a group.

Assuming that all of the ordinary shares represented by ADSs are held by residents of the United States, as of December 31, 2024, the Company
estimates  that  approximately  4.7  million  shares,  or  5.67%  of  the  outstanding  ordinary  shares  were  held  of  record  by  residents  of  the  United
States.

Beneficial ownership is determined according to the rules of the SEC and generally means that a person has beneficial ownership of a security if
he, she or it possesses sole or shared voting or investment power of that security, including free shares that vest within 60 days of April 25, 2025
and options and warrants that are currently exercisable or exercisable within 60 days of April 25, 2025. Ordinary shares subject to free shares,
options  and  warrants  currently  exercisable  or  exercisable  within  60  days  of April  25,  2025  are  deemed  to  be  outstanding  for  computing  the
percentage of ownership of the person holding these free shares, options or warrants and the percentage of ownership of any group of which the
holder is a member, but are not deemed outstanding for computing the percentage of any other person. Beneficial ownership representing less
than 1% is denoted with an asterisk (*).

Except as indicated by the footnotes below, the Company believes, based on the information furnished to us, that the persons named in the table
below  have  sole  voting  and  investment  power  with  respect  to  all  ordinary  shares  shown  that  they  beneficially  own,  subject  to  community
property laws where applicable. The information does not necessarily indicate beneficial ownership for any other purpose, including for purposes
of Sections 13(d) and 13(g) of the Securities Act.

Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Innate Pharma S.A., 117, Avenue de Luminy –
BP 30191, 13009 Marseille, France.

Arrangements with the Members of the Executive and Supervisory Boards

Director and Executive Officer Compensation

See “Item 6B—Compensation—Limitations on Liability and Indemnification Matters” for information regarding compensation of the members
of the Supervisory and Executive Boards.

On December 15, 2023, following Mondher Mahjoubi’s resignation from his position as Chairman of the Executive Board effective December
31, 2023, the Supervisory Board authorized the conclusion of a service agreement with him for the month of January 2024, for compensation
equivalent to his monthly fixed salary, i.e., the sum of €39,000

On January 3, 2024, following his appointment as Interim Chairman of the Executive Board, the Supervisory Board authorized the conclusion of
a mandate agreement between the Company and Hervé Brailly, which includes the benefit of a French pension contract of €5,503.28.

On January 3, 2024, following his appointment as Chief Operating Officer, member of the Executive Board, the Supervisory Board authorized
the  entry  into  of  an  amendment  to  an  employment  contract  between  the  Company  and  Yannis  Morel,  which  includes,  a  fixed  annual
remuneration of €300,000 and a French pension contract of €5,662.02.

On  January  3,  2024,  following  her  appointment  as  a  member  of  the  Executive  Board,  the  Supervisory  Board  authorized  the  entry  into  of  an
amendment  to  an  employment  contract  between  the  Company  and  Sonia  Quaratino,  which  includes  an  individual  bonus  of  40%  based  on
reaching certain specified targets, rising to 60% in the event of outperformance.

On October 11, 2024, the Supervisory Board authorized the conclusion of a consulting agreement with Addexpert and then, after expiration of
that agreement, with Kervrant Biotech, a company wholly owned by Hervé Brailly, to continue the consulting and support services for the new

depending on time spent.

On June 1, 2024, the Supervisory Board authorized the conclusion of a consulting agreement with Ariana Pharmaceuticals, a company in which
Véronique  Chabernaud  is  acting  CMO  and  Jean-Yves  Blay  is  a  scientific  advisor,  aimed  at  using  artificial  intelligence  to  accelerate  the
development of the Company's products.

On May 12, 2023, the Supervisory Board authorized the conclusion of an agreement between Innate Pharma and Jean-Yves Blay in his capacity
as a member of the Supervisory Board, to define the terms and conditions under which Jean-Yves Blay participates in the Supervisory Board.

Transaction with Related Companies

From time to time, in the ordinary course of its business, the Company may contract for services from companies or institutions in which certain
members of its Executive Board or Supervisory Board may serve as a director or advisor. The cost and provision of these services are negotiated
on an arm's-length basis, and none of these arrangements are material.

200

Related Person Transaction Policy

The Company complies with French law regarding approval of transactions with related parties. On September 12, 2019, the Supervisory Board
adopted a related person transaction policy that sets forth its procedures for the identification, review, consideration and approval or ratification
of related person transactions. The policy became effective immediately upon the execution of the underwriting agreement for the October 2019
global offering. For purposes of its policy only, a related person transaction is a transaction, arrangement or similar contractual relationship, or
any series of similar transactions, arrangements or relationships, in which the Company and any related person are, were or will be participants
and the amount involved in the transaction exceeds $120,000, with the exception of usual transactions concluded under normal conditions. A
related  person  is  any  member  of  the  Executive  Board  or  Supervisory  Board  or  beneficial  owner  of  more  than  5%  of  any  class  of  its  voting
securities, including any of their immediate family members and any entity owned or controlled by such persons.

Under  the  policy,  if  a  transaction  has  been  identified  as  a  related  person  transaction,  including  any  transaction  that  was  not  a  related  person
transaction  when  originally  consummated  or  any  transaction  that  was  not  initially  identified  as  a  related  person  transaction  prior  to
consummation,  the  management  must  present  information  regarding  the  related  person  transaction  to  the  Supervisory  Board  for  review,
consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests,
direct and indirect, of the related persons, the benefits to Innate of the transaction and whether the transaction is on terms that are comparable to
the terms available to or from, as the case may be, an unrelated third party or to or from employees generally. Under the policy, the Company
will collect information that the Company deems reasonably necessary from each member of its Executive Board and Supervisory Board and, to
the extent feasible, significant shareholder to enable Innate to identify any existing or potential related-person transactions and to effectuate the
terms of the policy.

In addition, under its Code of Business Conduct and Ethics, which Innate Pharma adopted on September 12, 2019, its employees and Executive
and Supervisory Board members have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected
to give rise to a conflict of interest.

In considering related person transactions, the Supervisory Board will take into account the relevant available facts and circumstances including,
but not limited to:

•

•

•

•

the risks, costs and benefits to us;

the impact on the independence of a member of the Executive Board or Supervisory Board in the event that the related person is a member
of the Executive Board or Supervisory Board, an immediate family member of a member of the Executive Board or Supervisory Board or
an entity with which a member of Executive Board or Supervisory Board is affiliated;

the availability of other sources for comparable services or products; and

the terms available to or from, as the case may be, unrelated third parties or to or from employees generally.

The policy requires that, in determining whether to approve, ratify or reject a related person transaction, the Supervisory Board must consider, in
light of known circumstances, whether the transaction is in, or is not inconsistent with, the Company's best interests and those of its shareholders,
as the Supervisory Board determines in the good faith exercise of its discretion.

All of the transactions described above were evaluated and approved by the Supervisory Board.

From time to time, the Company may be involved in various claims and legal proceedings relating to claims arising out of our operations. The
Company is not currently a party to any legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on
our business. Regardless of outcome, litigation can have an adverse impact on the Company because of defense and settlement costs, diversion
of management resources and other factors.

With respect to an arbitral decision rendered in December 2021 relating to milestone payments received by the Company under the collaboration
and option agreement that the Company signed the 2018 AZ Option Agreement, see Note 6 to the consolidated financial statements included as
part of this Annual Report.

Dividend Policy

The Company has never declared or paid any dividends on our ordinary shares. The Company does not anticipate paying cash dividends on our
equity securities in the foreseeable future and intends to retain all available funds and any future earnings for use in the operation and expansion
of our business, given our state of development.

Subject to the requirements of French law and our bylaws, dividends may only be distributed from our distributable profits, plus any amounts
held  in  our  available  reserves  which  are  reserves  other  than  legal  and  statutory  and  revaluation  surplus.  Dividend  distributions,  if  any  in  the
future, will be made in euro and converted into U.S. dollars with respect to the ADSs, as provided in the deposit agreement. See the information
set forth in our prospectus dated October 16, 2019, filed with the SEC pursuant to Rule 424(b), under the heading “Description of Share Capital”

shares underlying our ADSs. Holders of our ADSs have a right to receive the ordinary shares underlying their ADSs. For discussion on our ADSs
and ADS holder rights, please refer to Exhibit 2.3 “Description of Securities” of this Annual Report.

Corporate Purpose (Article 4 of the Bylaws)

Our corporate purpose, directly or indirectly, in France or other countries is to:

•

•

carry  out,  on  our  own  behalf  or  on  behalf  of  third  parties,  any  research,  development,  studies  and  development  of  manufacturing  or
marketing procedures for pharmaceutical products;

register or grant any patent or license directly or indirectly connected with our activity; and

• more generally, perform any operation of any kind, whether economic, legal, financial, civil or commercial, which may be directly or

indirectly related to our corporate purpose or any similar, associated or complementary purpose.

Executive Board (Articles 14 to 16 of the Bylaws)

The Executive Board is responsible for our management and is composed of a minimum of two members and a maximum of seven members
who perform their duties under the supervision of the Supervisory Board.

203

Members of the Executive Board

The  members  of  the  Executive  Board  are  appointed  or  have  their  appointments  renewed  by  the  Supervisory  Board.  The  members  of  the
Executive  Board  must  be  individuals.  They  are  not  required  to  be  shareholders.  They  may  be  French  citizens  or  citizens  of  other  countries.
Members of the Executive Board cannot be members of the Supervisory Board.

The maximum age for being a member of the Executive Board is 70 years. If the age limitation is exceeded, the term of the exceeding member
of the Executive Board expires during the General Meeting of the shareholders following the anniversary date.

The  limitations  on  having  an  appointment  concurrently  with  an  appointment  in  another  company  are  subject  to  the  applicable  legal  and
regulatory provisions.

The term of office for the members of the Executive Board is three years and may be renewed. If there is a vacancy, the Supervisory Board must
fill the vacancy within two months. The replacement is appointed for the time remaining until the Executive Board is up for renewal.

The members of the Executive Board may be removed from office, with or without cause and without notice, by the Supervisory Board or at any
General Meeting of shareholders, by a simple majority vote of the shareholders present and voting at the meeting in person or by proxy.

Chairman of the Executive Board

The Supervisory Board elects a Chairman from among the members of the Executive Board to serve for the duration of his appointment as a
member of the Executive Board. The Chairman of the Executive Board represents us in our relations with third parties.

The Supervisory Board may assign this power of representation to one or more other members of the Executive Board. Assignees have the title
of General Manager.

Meetings and Powers of the Executive Board

The Executive Board meets as often as is in our interest, but at least once per quarter. Meetings are called by the Chairman or a member of the
Executive Board appointed for this purpose.

At least three-quarters of the members of the Executive Board must be present or represented to constitute a quorum and decisions are made by a
majority of the members of the Executive Board present or represented. Each member has one vote. In case of equality of expressed votes either
in favor or against a decision (abstentions are not taken into account), the Chairman of the Executive Board has a casting vote.

The Executive Board has broad power to act under all circumstances on our behalf. It exercises this power within the limits of our corporate
purpose and subject to any powers expressly given to the Supervisory Board and Shareholders’ Meetings by law and according to our bylaws,
and abiding by any restrictions on powers decided by the Supervisory Board. There are currently no limits imposed on the amounts of loans or
borrowings that the Executive Board may approve.

Compensation of the Executive Board

The method and amount of compensation for each member of the Executive Board is determined by the Supervisory Board when appointing
such member, as the case may be.

Supervisory Board (Articles 17 to 22 of the Bylaws)

Members of the Supervisory Board

The Executive Board is supervised by a Supervisory Board made up of a minimum of three members and a maximum of eighteen. The members
of the Supervisory Board are appointed for a renewable term of

204

two years at the general meeting of shareholders, which may revoke their appointments at any time. The appointees are selected from among the
shareholders or not, and may be individuals or companies. Each member must own at least one of our ordinary shares for the entire term of the
appointment. Members of the Supervisory Board cannot be members of the Executive Board.

The number of members of the Supervisory Board who have reached the age of seventy years cannot be higher than a third of the members of
the Supervisory Board. If the age limitation is exceeded, the eldest member is deemed to have resigned automatically.

Chairman of the Supervisory Board

The Supervisory Board appoints from its members who are individuals a Chairman and a Vice-Chairman, who are in charge of convening the
Supervisory Board and leading the debates.

Meetings and Powers of the Supervisory Board

The Supervisory Board meets as often as is in our interests but at least once per quarter. Meetings are called by the Chairman or Vice-Chairman,
or by a member of the Executive Board or at least one-third of the members of the Supervisory Board, under the circumstances and according to
the conditions set forth in the bylaws.

At  least  half  of  the  members  of  the  Supervisory  Board  must  be  present  (or  deemed  present  in  case  of  use  of  videoconference  or  any  other
telecommunication means) to constitute a quorum and decisions are made by a majority of the members of the Supervisory Board present (or
deemed present in case of use of videoconference or any other telecommunication means) or represented, it being specified that in a case of a
split-vote, the Chairman of the meeting shall have the tiebreaking vote.

The Supervisory Board exercises permanent control over our management by the Executive Board and the powers explicitly conferred on it by
the French laws. It alone has the authority to authorize certain significant transactions.

Under French law, any agreement entered into, directly or through an intermediary, between us and one of the members of the Executive Board
or Supervisory Board, or a shareholder that holds over 10% of the voting rights, or, if such shareholder is a company, the controlling company
thereof, must be subject to prior authorization from the Supervisory Board. The interested member cannot participate in the deliberations, nor
vote on such decision. The same applies to agreements in which a person referred above has an indirect interest. Such prior authorization also
applies  to  agreements  between  us  and  another  company  if  one  of  the  members  of  our  Executive  Board  or  Supervisory  Board  is  the  owner,  a
partner  with  unlimited  liability,  manager,  director,  managing  director,  member  of  the  Executive  Board  or  of  the  Supervisory  Board,  or,  in  a
general manner is in a position of responsibility within the other company. These provisions are not applicable to agreements concerning day-to-
day operations entered into under normal conditions.

In a report to the General Meeting of shareholders attached to the Executive Board’s Management Report, the Supervisory Board reports on the
conditions for preparing and organizing the work of the Supervisory Board as well as the internal control procedures set up by us.

Compensation of the Supervisory Board

Compensation  for  their  attendance  at  board  meetings  (formerly  known  as  jetons  de  présence)  is  determined  at  the  annual  ordinary  General
Meeting.  The  General  Meeting  of  shareholders  may  allocate  an  annual  fixed  sum  and  our  Supervisory  Board  allocates  this  sum  among  its
members as it sees fit. In addition, the Supervisory Board may allocate exceptional compensation (rémunération exceptionnelle) for missions or
mandates entrusted to its members; in this case, this remuneration is subject to the provisions regarding related-parties agreements.

205

Committees

The Supervisory Board may decide to establish committees responsible for reviewing matters which the Supervisory Board or its Chairman wish
to submit to them for examination and advice.

Observers (Article 23 of the Bylaws)

At the general meeting of shareholders, one or more observers (censeurs) may be appointed, at the discretion of the shareholders for a term of
office  expiring  at  the  shareholders  meeting  convened  to  decide  on  the  financial  statements  for  the  preceding  financial  year  after  the  first
anniversary date of their appointment. This mandate is renewable without limit. Observers may be individuals or companies and are not required
to be shareholders.

The  observers  attend  all  Supervisory  Board  meetings,  with  the  right  to  participate  but  with  a  consultative  vote  only.  They  hold  the  same
information and communication rights than the Supervisory Board’s members and they are bound to the same confidentiality obligations.

General Meeting of Shareholders (Articles 26 to 37 of the Bylaws)

Calling Meetings and Conditions for Admission (Articles 27 to 30 of the Bylaws)

General Meetings of shareholders are called by the Executive Board, or failing that, by the Supervisory Board. They can also be called by the
auditor(s) or an officer appointed by a court upon request, by any interested party or by the Works Council in an emergency, by one or more
shareholders  holding  at  least  five  percent  of  the  ordinary  shares  or  by  an  association  of  our  shareholders.  Meetings  are  held  at  our  registered

announcements in the department where the headquarters are located, and in the BALO. Holders of registered shares who have owned them for
at least one month as of the date on which the latest notice is published receive individual notices. When a General Meeting of shareholders is
unable  to  take  action  because  the  requisite  quorum  is  not  present,  a  second  meeting  is  called  at  least  ten  days  in  advance  using  the  same
procedure as the first one.

The General Meeting of shareholders may only take action on items on the agenda. However, it may dismiss and replace one or more members
of the Supervisory Board at any time. The General Meeting may also dismiss the members of the Executive Board. One or more shareholders
representing  at  least  the  percentage  of  share  capital  fixed  by  law,  and  acting  according  to  the  legally  required  conditions  and  deadlines,  are
allowed to request that items and/or draft resolutions be added to the agenda of the General Meeting of shareholders.

Each shareholder has the right to attend the meetings and take part in deliberation (i) personally; (ii) by granting proxy to another shareholder,
his or her spouse or partner in a civil union or any other natural or legal person of his or her choice; (iii) by sending a proxy to the Company

Strategic Collaborations and License Agreements

AstraZeneca

Co-Development Agreement (monalizumab)

In October 2018, the Company entered into a co-development and license agreement relating to all products containing monalizumab (the "Co-
Development Agreement") with MedImmune, a wholly owned subsidiary of AstraZeneca, which Innate refers to as AstraZeneca. Under the Co-
Development Agreement,  the  Company  granted  to AstraZeneca  a  worldwide,  exclusive  license,  subject  to  certain  exclusions,  to  certain  of  its
patents  and  know-how  to  develop,  manufacture  and  commercialize  licensed  products,  including  monalizumab,  in  the  field  of  diagnosis,
prevention and treatment of oncology diseases and conditions. The Company further granted to AstraZeneca a worldwide, non-exclusive license
to certain of its other patents to develop, manufacture and commercialize licensed products, including monalizumab, in the field of diagnosis,
prevention  and  treatment  of  oncology  diseases  and  conditions.  The  Company  retains  the  rights  under  the  licensed  patents  and  know-how  to,
among other things, co-promote licensed products in certain European countries,pursuant to its option to co-promote, and exploit the licensed
patents and know-how to research, develop and commercialize the licensed products outside of the field of diagnosis, prevention and treatment
of oncology diseases and conditions.

Under  the  Co-Development  Agreement,  the  Company  is  required  to  collaborate  with  AstraZeneca  to  develop  and  commercialize  licensed
products. AstraZeneca will be the lead party in developing the licensed products and licensed product in certain major markets. Each party will
have to use

207

commercially reasonable efforts to complete certain development activities in accordance with a specified development plan.

The Company is required for a defined period of time to co-fund 30% of the Phase 3 clinical trials of licensed products, subject to an aggregate
cap, in order to receive 50% of the profits in Europe.

On July 31, 2019, the Company notified AstraZeneca of its decision to co-fund future monalizumab Phase 3 clinical development program. In
October 2020, AstraZeneca enrolled the first patient in the first Phase 3 trial which triggered a $50 million milestone payment from AstraZeneca
to Innate.

In  August  2022,  the  Company  announced  that  the  planned  futility  interim  analysis  of  the  INTERLINK-1  Phase  3  study  sponsored  by
AstraZeneca did not meet a pre-defined threshold for efficacy. Based on this result and the recommendation of an Independent Data Monitoring
Committee, AstraZeneca has informed Company that the study will be discontinued.

In September 2021, AstraZeneca, based on data from the randomized Phase 2 trial in patients with unresectable, Stage III non-small cell lung
cancer (NSCLC) presented at the European Society for Medical Oncology (ESMO) Congress, announced plans to initiate a Phase 3 trial for both
combinations of monalizumab or oleclumab plus durvalumab in the unresectable, Stage III NSCLC setting for patients who had not progressed
after concurrent chemoradiationtherapy.

In April 2022, the Company announced that AstraZeneca enrolled the first patient in a second Phase 3 trial, PACIFIC-9, evaluating durvalumab
in  a  combination  with  monalizumab  or  oleclumab  in  patients  with  unresectable,  Stage  III  NSCLC,  which  triggered  a  $50  million  milestone
payment from AstraZeneca Innate.

Separately, AstraZeneca also announced that it is starting a Phase 2 clinical trial, NeoCOAST-2, that includes a treatment arm with durvalumab
in combination with chemotherapy and monalizumab in resectable, early-stage NSCLC.

AstraZeneca is responsible for the promotion of licensed products worldwide, subject to Innate's option to co-promote the licensed products in
certain European countries. Should the Company elect not to co-promote, its share of profits in Europe will be reduced by a specified amount of
percentage points not to exceed the mid-single digits.

The  development  by AstraZeneca  of  a  licensed  product  under  the  Co-Development Agreement  is  subject  to  certain  reciprocal  non-compete
obligations.

AstraZeneca  is  obligated  to  pay  Innate  up  to  $775  million  in  the  aggregate  upon  the  achievement  of  certain  development  and  regulatory
milestones ($350 million), and commercialization milestones ($425 million). As described above, the arrangement also provides for a 50% profit
share and, subject to certain deferrals of reimbursement, loss share of licensed products in Europe if the Company does not opt out of its co-
funding and co-promoting obligations. In addition, the Company will be eligible to receive tiered royalties ranging from a low double-digit to
mid-teen percentage on net sales of licensed products outside of Europe. The royalties payable to Innate under the Co-Development Agreement
may be reduced under certain circumstances, including loss of exclusivity or lack of patent protection.

Innate's  right  to  receive  royalties  under  the  Co-Development Agreement  expires,  on  a  licensed  product-by-licensed  product  and  country-by-
country basis, on the latest of: (i) the tenth anniversary of the first commercial sale of such licensed product in such country, or in the case of
European countries, in any European country, (ii) the expiration of regulatory exclusivity for such licensed product in such country and (iii) the
expiration of the last-to-expire valid licensed patent claim subject to the agreement that covers such licensed product in such country.

208

Unless earlier terminated, the term of the Co-Development Agreement will expire on the date on which all of AstraZeneca’s payment obligations
have  expired.  The  Company  may  terminate  the  Co-Development  Agreement  if  AstraZeneca  challenges  any  patent  licensed  to  it  under  the
agreement. AstraZeneca may terminate the Co-Development Agreement in its entirety for convenience at any time effective upon 120 days’ prior
written notice to us. Either party may terminate the Co-Development Agreement in the event of an uncured material breach by the other party or
for certain bankruptcy or insolvency events involving the other party.

If the Co-Development Agreement is terminated by AstraZeneca for convenience or by Innate for AstraZeneca’s material breach, insolvency or a
patent  challenge  by  AstraZeneca,  all  licenses  and  rights  granted  under  the  agreement  terminate,  however,  upon  any  such  termination,
AstraZeneca would grant Innate an exclusive, worldwide, royalty-bearing right and license, with the right to grant sublicenses, under technology
developed  by  AstraZeneca  and  incorporated  into  or  necessary  for  the  exploitation  of  licensed  products,  except  for  certain  manufacturing
technology that would require a separate agreement. If the Co-Development Agreement is terminated by AstraZeneca for Innate's material breach
or insolvency, AstraZeneca has the right to continue the agreement by providing written notice to us. If AstraZeneca provides Innate with such
written  notice,  among  other  things,  its  rights  under  the  co-promote  option  will  terminate  and  the  Company  must  cease  any  development,
manufacture or commercialization activities under the agreement.

Collaboration and Option Agreement with AstraZeneca relating to CD39

In  October  2018,  the  Company  entered  into  a  collaboration  and  option  agreement  relating  to  IPH5201,  or  the  CD39  Option Agreement. The
Company received an initial payment of $50 million under this agreement, $26 million of which was received in October 2018 and $24 million
of which was received in January 2019. Pursuant to the 2018 CD39 Option Agreement, the Company granted to AstraZeneca an exclusive option
to obtain an exclusive license to certain of its patents and know-how to develop and commercialize licensed products, including IPH5201 in the
field of the diagnosis, prevention and treatment of all diseases and conditions in humans or animals, subject to certain limitations.

Under  the  2018  CD39  Option  Agreement,  the  Company  must  collaborate  with  AstraZeneca  to  develop  CD39  option  products.  Prior  to  the
expiration of the option period, the Company and AstraZeneca are subject to certain non-compete obligations.

AstraZeneca is responsible for funding the research and development costs of CD39 option products contemplated in the joint development plan.
Additionally,  the  Company  may  conduct  certain  exploratory  clinical  studies  at  its  own  cost,  subject  to  reimbursement  by AstraZeneca  with  a
premium under certain circumstances related to subsequent development by AstraZeneca.

Following  the  dosing  of  the  first  patient  on  March  9,  2020  in  the  IPH5201  Phase  1  clinical  trial, AstraZeneca  made  a  $5  million  milestone
payment to Innate.

In  June  2022,  the  2018  CD39  Option  Agreement  was  amended.  Innate  received  a  $5  million  milestone  payment  from  AstraZeneca  upon
signature of the amendment and is responsible for conducting a new Phase 2 multicenter, open label, non-randomized study of neoadjuvant and
adjuvant treatment with IPH5201, durvalumab and chemotherapy in patients with resectable, early-stage non-small cell lung cancer (NSCLC).
The "MATISSE" Study has started. AstraZeneca and Innate will share study costs and AstraZeneca will supply clinical trial drugs. Innate made a
€0.6 million milestone payment to Orega Biotech SAS pursuant to Innate’s exclusive licensing agreement (see below).

209

On June 26, 2023, the Company announced the first patient was dosed in MATISSE, a Phase 2 multicenter single-arm study (NCT05742607),
sponsored  by  the  Company,  evaluating  neoadjuvant  and  adjuvant  treatment  with  IPH5201,  an  anti-CD39  blocking  monoclonal  antibody,  in
combination with durvalumab (anti-PD-L1) and chemotherapy, in treatment-naïve patients with resectable early stage non-small cell lung cancer
(NSCLC). The primary objectives of the study are to assess antitumor activity of neoadjuvant treatment based on pathological complete response
(pCR) and safety. The Company is responsible for conducting the study and shares study costs with AstraZeneca. AstraZeneca supplies clinical
trial  drugs.  More  information  about  the  Phase  2  MATISSE  trial,  see  “Item  4.B—Business  Overview—IPH5201,  an  Anti-CD39  Antibody
Targeting  the  Immunosuppressive Adenosine  Pathway.”  The  Company  received  a  $5  million  milestone  payment  from AstraZeneca  when  the
decision was made to progress IPH5201 to a Phase 2 clinical trial.

Unless earlier terminated, the term of the 2018 CD39 Option Agreement will expire on the earlier of exercise of the option or expiration of the
option  period  in  the  event  that AstraZeneca  does  not  exercise  the  option. The  Company  may  terminate  the  2018  CD39  Option Agreement  if
AstraZeneca challenges any option patent. AstraZeneca may terminate the 2018 CD39 Option Agreement in its entirety for convenience at any
time effective upon three months’ prior written notice to us. Either party may terminate the 2018 CD39 Option Agreement in the event of an
uncured material breach by the other party or for certain bankruptcy or insolvency events involving the other party.

CD39 Co-Development and License Agreement Upon Option Exercise by AstraZeneca

Upon exercise of the option under the 2018 CD39 Option Agreement, the Company would enter into a co-development and license agreement
with  AstraZeneca,  or  the  CD39  Potential  License  Agreement.Under  the  CD39  Potential  License  Agreement,  the  Company  would  grant  to
AstraZeneca a worldwide,exclusive license, subject to certain exclusions, to certain of its patents and know-how regarding, among other things,
its  IPH5201  candidate,  to  develop,  manufacture  and  commercialize  licensed  products  in  the  field  of  diagnosis,  prevention  and  treatment  of
diseases and conditions in humans and in animals, subject to certain limitations. The Company would retain certain rights under the licensed
patents and know-how to, among other things, co-promote licensed products in certain European countries, pursuant to its option to co-promote.

The CD39 Potential License Agreement provides for a payment of $25 million upon exercise. Additionally, AstraZeneca would be obligated to
pay  Innate  up  to  $795  million  in  the  aggregate  upon  the  achievement  of  certain  development  and  regulatory  milestones  ($295  million)  and
commercialization milestones ($500 million). The arrangement also provides for a 50% profit share in Europe if the Company opts into certain
co-promoting and late stage co-funding obligations. In addition, the Company would be eligible to receive tiered royalties ranging from a high-
single digit to mid-teen percentage on net sales of IPH5201, or from a mid-single digit to low-double digit percentage on net sales of other types
of  licensed  products,  outside  of  Europe. The  royalties  payable  to  Innate  under  the  CD39  Potential  License Agreement  may  be  reduced  under
certain circumstances, including loss of exclusivity or lack of patent protection.

Under the CD39 Potential License Agreement, unless the Company has elected not to co-fund, the Company would be required to collaborate
with AstraZeneca to develop and commercialize licensed products. AstraZeneca would be the lead party in developing and commercializing the
licensed products and each party must use commercially reasonable efforts to develop, obtain regulatory approval and commercialize at least one
licensed product in certain major markets. Each party would have to use commercially reasonable efforts to complete its development activities
in accordance with a specified development plan.

210

The Company would have the option to co-fund 30% of the Phase 3 clinical trials of licensed products in order to share in 50% of the profits and
losses of licensed products in Europe. If the Company does not exercise this co-funding option, among other things, its right to share in 50% of
the profits and losses in Europe and right to co-promote in certain European countries will terminate and will be replaced by rights to receive
royalties on net sales at the rates applicable to outside of Europe. Additionally, certain milestone payments that may be payable to Innate would
be reduced. AstraZeneca would be responsible for the promotion of licensed products worldwide, subject to its option to co-promote the licensed
products in certain European countries if the Company elects to co-fund. Additionally, the Company would have a right of first negotiation in the
event that AstraZeneca wishes to grant a third-party the right to commercialize licensed products in Europe or the United States.

The  development  by AstraZeneca  of  a  licensed  product  under  the  Potential  License Agreement  is  subject  to  certain  reciprocal  non-compete
obligations.

Innate's right to receive royalties under the CD39 Potential License Agreement expires, on a licensed product-by-licensed product and country-
by-country basis, on the latest of: (i) the tenth anniversary of the first commercial sale of such licensed product in such country, or, in the case of
European countries, in any European country, (ii) the expiration of regulatory exclusivity for such licensed product in such country and (iii) the
expiration of the last-to-expire valid licensed patent claim subject to the agreement that covers such licensed product in such country.

Unless earlier terminated, the term of the CD39 Potential License Agreement would expire on the date on which all of AstraZeneca’s payment
obligations have expired. The Company may terminate the CD39 Potential License Agreement if AstraZeneca challenges any patent licensed to
it under the agreement.AstraZeneca may terminate the CD39 Potential License Agreement in its entirety for convenience at any time effective
upon 120 days’ prior written notice to us. Either party may terminate the CD39 Potential License Agreement in the event of an uncured material
breach by the other party or for certain bankruptcy or insolvency events involving the other party.

Novo Nordisk A/S

Development and License Agreement relating to monalizumab

On February 5, 2014, the Company in-licensed the full development and commercialization rights to monalizumab from Novo Nordisk A/S. In
consideration for these rights, the Company paid Novo Nordisk A/S €2 million in cash and 600,000 of its ordinary shares at a price of €8.33 per
share.  Novo  Nordisk  A/S  is  eligible  to  receive  a  total  of  €20  million  in  potential  regulatory  milestones  and  tiered  mid-to-high  single-digit
percentage royalties on future net sales.

The agreement with Novo Nordisk A/S included a right to additional consideration in the event of an out-licensing agreement. Consequently,
following the agreement signed with AstraZeneca in April 2015, the Company paid Novo Nordisk A/S an additional consideration amount of
€6.5 million.

In October 2018 AstraZeneca exercised its option under the 2015 Option Agreement to acquire an exclusive license to monalizumab. Pursuant to
this option exercise, AstraZeneca paid $100 million to Innate and, as a result, Novo Nordisk A/S became entitled to a second and final payment
amounting to $15.0 million (€13.1 million). If the AstraZeneca agreement is terminated for any reason, the Company will pay to Novo Nordisk
A/S a portion of any amounts that have been budgeted but have not been spent or will not be spent under the initial research and development
budget. In light of current development plans and research and development costs incurred to date, the Company does not currently expect any
amounts to be paid pursuant to this provision.

211

License Agreement relating to avdoralimab

In July of 2017 the Company entered into an exclusive license agreement with Novo Nordisk A/S relating to avdoralimab, or the 2017 Novo
Agreement, pursuant to which the Company obtained a worldwide, exclusive license under certain patents and know-how of Novo Nordisk A/S
to develop, manufacture and commercialize pharmaceutical products that contain or comprise an Anti-C5aR antibody. The Company made an
initial  payment  to  Novo  Nordisk  A/S  of  €40.0  million  under  the  2017  Novo  Agreement  which  was  offset  against  Novo  Nordisk  A/S’s
subscription  in  new  shares. The  Company  is  obligated  to  pay  Novo  Nordisk A/S  in  the  aggregate  up  to  €370.0  million  upon  achievement  of
certain development, regulatory and sales milestones and tiered royalties ranging from a low double-digit to low teen percentage on net sales.
The Company's royalty payment obligations are subject to certain reductions and expire on a product-by-product and country-by-country basis
upon the later of the date the exploitation of a licensed product is no longer covered by a claim of a licensed patent in such country, loss of data
or regulatory exclusivity in such country, and the twelfth anniversary of the first commercial sale of such product in such country. In connection
with the 2017 Novo Agreement, the Company obtained an exclusive sublicense from Novo Nordisk A/S under certain third-party intellectual
property  rights.  In  consideration  for  such  sublicense,  the  Company  may  be  obligated  to  pay  a  mid-single  digit  royalty  on  its  net  sales  of  a
licensed product, however, the Company will be entitled to offset such payments against royalties payable to Novo Nordisk A/S.

Under the 2017 Novo Agreement, the Company is obligated to use commercially reasonable efforts to develop and seek regulatory approval for a
licensed product.

The 2017 Novo Agreement shall expire upon expiration of the last royalty payment obligation under the agreement. Either party may terminate
the 2017 Novo Agreement upon any uncured material breach of the agreement by the other party or upon a bankruptcy or insolvency of the other
party.  Additionally,  Novo  Nordisk  A/S  may  terminate  the  agreement  in  the  event  the  Company  challenges  any  patent  licensed  under  the
agreement. The Company may terminate the 2017 Novo Agreement upon prior notice to Novo Nordisk A/S.

In 2020, the Company made a payment to Novo Nordisk A/S of €1 million under the 2017 Novo Agreement, covered by Bpifrance funding, in
respect of the start of a Phase 2 clinical trial of avdoralimab in COVID-19 patients with severe pneumonia. In July 2021, based on the Phase 2
clinical  trial  of  avdoralimab  in  COVID-19  patients  with  severe  pneumonia,  results  of  which  did  not  meet  its  primary  endpoints  in  all  three
cohorts of the trial, the Company has stopped stop exploring avdoralimab in COVID-19.

Following a strategic review in 2021, the Company was solely pursuing avdoralimab in bullous pemphigoid ("BP"), an inflammatory disease,
through an investigator-sponsored study and stopped further development in all other indications.

In last quarter of 2022, the Company was informed by the Sponsor, the Centre Hospitalier Universitaire de Nice, that the ongoing Phase 2 study
for the treatment of BP will be discontinued. Consequently, the Company decided to stop further development in BP indication and will continue
to review its strategy on avdoralimab.

Sanofi

Collaboration and Licensing agreement (2016) IPH6101 and IPH6401

IPH6101

The Company entered into a research collaboration and licensing agreement with Sanofi in January 2016 to apply its proprietary technology to
the development of bispecific antibody formats engaging NK cells

212

to  kill  tumor  cells  through  the  activating  receptor  NKp46.  The  Company  granted  to  Sanofi  under  certain  of  its  intellectual  property  a  non-
exclusive, worldwide, royalty-free research license, as well as an exclusive, worldwide license to research, develop and commercialize products
directed against two specified targets, for all therapeutic, prophylactic and diagnostic indications and uses.

The Company will work together with Sanofi on the generation and evaluation of up to two bispecific NK cell engagers, using its technology
and  Sanofi’s  tumor  targets.  Under  the  terms  of  the  license  agreement,  Sanofi  will  be  responsible  for  the  development,  manufacturing  and
commercialization of products resulting from the research collaboration. The Company will be eligible for up to €192.0 million in payments,
primarily  upon  the  achievement  of  development  and  commercial  milestones,  as  well  as  royalties  ranging  from  a  mid  to  high  single-digit
percentage on net sales.

On January 5, 2021, the Company announced that Sanofi has made the decision to progress IPH6101/SAR443579 into investigational new drug
(IND)  enabling  studies.  IPH6101/SAR443579  is  a  NKp46-based  NK  cell  engager  (NKCE)  using  Innate’s  proprietary  multi-specific  antibody
format.  The  decision  triggered  a  €7  million  milestone  payment  from  Sanofi  to  Innate.  Sanofi  will  be  responsible  for  all  future  development,
manufacturing  and  commercialization  of  IPH6101/SAR443579. Additionally,  in  January  2021,  a  GLP-toxicology  study  was  initiated  for  the
IPH6101/SAR443579  program.  In  December  2021,  the  Company  announced  that  the  first  patient  was  dosed  in  a  Phase  1/2  clinical  trial,
evaluating  IPH6101/SAR443579,  in  patients  with  relapsed  or  refractory  acute  myeloid  leukemia  (R/R  AML),  B-cell  acute  lymphoblastic
leukemia  (B-ALL)  or  high  risk-myelodysplastic  syndrome  (HR-MDS).  The  start  of  the  trial  triggered  a  milestone  payment.  The  Company
received €3.0m from Sanofi following the initiation of a GLP-tox Study and the launching of the first Phase 1 clinical trial in humans in relapsed
of refractory AML with IPH6101/SAR443579, respectively in January and December 2021.

In April  2024,  Sanofi  advanced  SAR’579  /  IPH6101,  to  the  Phase  2  preliminary  dose  expansion  of  the  trial.  Under  the  terms  of  the  research
collaboration  and  licensing  agreement,  the  progression  to  the  dose  expansion  part  of  the  trial  triggered  a  milestone  payment  from  Sanofi  to
Innate of €4 million.

On April  23,  2025,  the  Company  announced  that,  in  alignment  with  both  company's  current  strategic  priorities,  Sanofi  and  Innate  agreed  to
terminate the 2016 Agreement as it relates to SAR’579/IPH6101 (CD123 ANKET®), effective as of June 30, 2025. Innate will regain its rights
on July 1, 2025.

IPH6401

In July 2022, the Company announced that Sanofi has made the decision to progress IPH6401/SAR’514 into investigational new drug (IND)
enabling studies, triggering a €3 million milestone payment.

On  July  11,  2023,  the  Company  announced  that  the  first  patient  was  dosed  in  a  Sanofi-sponsored  Phase  1/2  clinical  trial  (NCT05839626),
evaluating SAR’514 / IPH6401 in relapsed/refractory multiple myeloma (RRMM) and Relapsed/Refractory Light-chain Amyloidosis (RRLCA).
SAR’514 is a trifunctional anti-BCMA NKp46xCD16 NK cell engager, using Sanofi’s proprietary CROSSODILE® multi-functional platform,
which comprises the Cross-Over-Dual-Variable-Domain (CODV) format. It induces a dual targeting of the NK activating receptors, NKp46 and
CD16, for an optimized NK cell activation, based on the Company’s ANKET  proprietary platform. The purpose of the dose escalation and dose
expansion study is to evaluate the safety, pharmacokinetics and preliminary efficacy of SAR’514 in monotherapy in patients with RRMM and
RRLCA.  The  start  of  the  trial  has  triggered  a  milestone  payment  from  Sanofi  to  Innate,  which  is  part  of  a  previously  announced  research
collaboration

®

213

with Sanofi. More information about the Phase 1/2 trial, see “Item 4.B—Business Overview—IPH6401/SAR’514, a BCMA-targeting NK Cell
Engager.”

The  Company  announced  on  March  27,  2025,  that  the  clinical  study  will  be  terminated  early  as  Sanofi  will  now  pursue  the  development  of
IPH6401/SAR'514 in autoimmune indications.

Research Collaboration and Licensing agreement (2022) relating to Innate’s ANKET® program - IPH62 and IPH67

IPH62

In  December  2022,  the  Company  entered  into  a  research  collaboration  and  licensing  agreement  with  Genzyme  Corporation,  a  wholly  owned
subsidiary of Sanofi under which the Company grants Sanofi an exclusive license to Innate’s B7H3 ANKET  program (IPH62) and options for
two  additional  targets  to  be  named.  Upon  candidate  selection,  Sanofi  will  be  responsible  for  all  development,  manufacturing  and
commercialization.

®

Under the terms of the research collaboration and license agreement, Innate has received in March 2023 €25 million as upfront payment and will
receive,  during  the  term  of  the  Research  and  Collaboration  Agreement,  up  to  €1.35  billion  total  in  preclinical,  clinical,  regulatory  and
commercial milestones plus royalties on potential net sales.

IPH67

®

On  December  19,  2023,  Innate  announced  that  Sanofi  had  exercised  its  option  to  license  a  natural  killer  (NK)  cell  engager  program  in  solid
tumors  from  the  Company’s ANKET   platform  (IPH67)  pursuant  to  the  terms  of  the  research  collaboration  and  license  agreement  signed  in
December  2022.  Following  a  research  collaboration  period,  Sanofi  will  be  responsible  for  all  development,  manufacturing  and
commercialization. Sanofi still retains the option to one additional ANKET target as per the research collaboration and licensing agreement with
Genzyme Corporation. Under the terms of the research collaboration and licensing agreement, the Company has received a €15 million payment
for the exercise of this option. The Company is eligible for up to €1.35 billion total in preclinical, clinical, regulatory and commercial milestones
plus royalties on potential net sales.

® 

During the third quarter 2024, Sanofi terminated the IPH67 license. As a consequence, Innate has regained the full rights to IPH67, an NK-cell
engager program in solid tumors from Innate’s ANKET® platform. As a result of such termination and resumptions of rights, Sanofi retains a
right to compensation regarding any future revenue that Innate Pharma may receive for licenses of or assigning rights related to Nectin-4, as well
as payments based on milestones upon certain authorizations being obtained should the Company develop IPH67 itself, and an ongoing royalty
fee in the low-single digits on future net sales. The rest of the 2022 research collaboration and license agreement remains unchanged.

Orega

Orega License Agreement with Orega relating to IPH5201

Pursuant  to  its  licensing  agreement  with  Orega  Biotech,  Innate  acquired  an  exclusive  license  to  Orega  Biotech’s  intellectual  property  rights
relating to its anti-CD39 checkpoint inhibitor program. As of December 31, 2018, the Company had paid a total amount of €1.8 million to Orega
Biotech for the acquisition of these intellectual property rights, and in June 2019, the Company paid Orega Biotech €7.0 million in relation to the
anti-CD39 program as consideration relating to the 2018 AZ Option Agreement. Following the dosing of the first patient on March 9, 2020 in the
IPH5201 Phase 1 clinical trial, AstraZeneca made a $5 million milestone pursuant to Innate’s collaboration agreement with AstraZeneca

214

and  Innate  made  a  €2.5  million  milestone  payment  in April  2020  and  a  €0.2  million  milestone  payment  in  June  2020  to  Orega  Biotech  SAS
pursuant to its licensing agreement with Orega Biotech SAS. In June 2022, Innate received a $5 million milestone payment from AstraZeneca
upon signature of an amendment to the 2018 CD39 Option Agreement (see above) and made a €0.6 million milestone payment to Orega Biotech
SAS pursuant to its licensing agreement with Orega Biotech SAS.

Unless earlier terminated, the Company may also pay Orega Biotech up to an additional €47 million in the aggregate upon the achievement of
development and regulatory milestones. Finally, the Company will be required to pay a low-teen percentage of sub-licensing revenues received
by the Company pursuant to its agreement with AstraZeneca regarding IPH5201.

Bank Loans

On July 17, 2017, the Company entered into one loan agreement with Société Générale, pursuant to which the Company obtained a financing in
an amount equal to €15.2 million with a term of 12 years.

On December 22, and December 17, 2021, the Company entered into two loan agreements with Société Générale and BNP Paribas, respectively,
pursuant to which the Company obtained non-dilutive financing in an aggregate amount equal to €28.7 million.

The two loans have an initial term of one year with an extension up to five years at Innate’s option. They are 90% guaranteed by the French state
(“PGE”) as part of the package of measures put in place by the French government to support companies during the COVID-19 pandemic.

In August 2022, the Company requested the extension of these two loans repayment for an additional period of five years starting in 2022 and
including a one-year grace period (2023). Consequently, the Company has obtained agreements from Société Générale and BNP Paribas. The
effective interest rates applied to these contracts during the additional period are 1.56% and 0.95% for Société Générale and BNP Paribas loans,
respectively,  excluding  insurance  and  guarantee  fees,  with  an  amortization  exemption  for  the  entire  year  2023.  During  this  grace  period,  the
Company was only liable for the payment of interest and the guarantee fees, with amortization of the two loans starting in 2024 over a period of
four years.

The summaries provided above do not purport to be complete and are qualified in their entirety by reference to the complete agreements, which
are attached as exhibits to this Annual Report on Form 20-F. For additional information on its material contracts, please see “Item 4. Information
on the Company,” “Item 6. Directors, Senior Management and Employees,” and “Item 7.B. Related Party Transactions” of this Annual Report on

Exchange Controls.

Under current French foreign exchange regulations there are no restrictions on the amount of cash transfers that may be made to residents of
foreign countries (subject to the absence of any specific decision taken by the government otherwise). Laws and regulations concerning foreign
exchange  controls  do,  however,  require  that  all  payments  or  transfers  of  funds  made  by  a  French  resident  to  a  non-resident  such  as  dividend
payments  be  handled  by  an  accredited  intermediary.  All  registered  banks  and  substantially  all  credit  institutions  in  France  are  accredited
intermediaries. For completeness, there is a reporting obligation to the custom officer for transfer of cash in banknotes and coins of €10,000 or
more carried into, or out of, the European Union.

Taxation.

Material U.S. Federal Income Tax Considerations

The following describes material U.S. federal income tax considerations relating to the acquisition, ownership and disposition of the ordinary
shares or ADSs by a U.S. holder (as defined below) who hold the ordinary shares or ADSs as capital assets. This summary does not address all
U.S. federal income tax matters that may be relevant to a particular U.S. holder, such as the effects of Section 451(b) of the Code. This summary
does  not  address  tax  considerations  applicable  to  a  holder  of  the  ordinary  shares  or ADSs  that  may  be  subject  to  special  tax  rules  including,
without limitation, the following:

•

•

•

•

•

•

•

•

•

•

•

banks, financial institutions or insurance companies;

brokers, dealers or traders in securities, currencies, commodities, or notional principal contracts;

tax-exempt entities or organizations, including an “individual retirement account” or “Roth IRA” as defined in Section 408 or 408A of the
Code (as defined below), respectively;

real estate investment trusts, regulated investment companies or grantor trusts;

persons that hold the ordinary shares or ADSs as part of a “hedging,” “integrated,” “wash sale” or “conversion” transaction or as a position
in a “straddle” for U.S. federal income tax purposes;

S corporations, partnerships, or other entities or arrangements classified as partnerships, for U.S. federal income tax purposes;

certain former citizens or long-term residents of the United States;

persons that received the ordinary shares or ADSs as compensation for the performance of services;

persons acquiring the ordinary shares or ADSs in connection with a trade or business conducted outside of the United States, including a
permanent establishment or a fixed base in France;

holders that own directly, indirectly, or through attribution 10% or more of the voting power or value of the ordinary shares or ADSs; and

holders that have a “functional currency” other than the U.S. dollar.

Holders of the ordinary shares or ADSs who fall within one of the categories above are advised to consult their tax advisor regarding the specific
tax consequences which may apply to their particular situation.

For the purposes of this description, a “U.S. holder” is a beneficial owner of the ordinary shares or ADSs that is (or is treated as), for U.S. federal
income tax purposes:

•

•

•

•

an individual who is a citizen or resident of the United States;

a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or
the District of Columbia;

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

a trust, if a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have
the authority to control all of the substantial decisions of such trust, or if such trust has a valid election in effect under applicable U.S.
Treasury Regulations to be treated as a U.S. person.

If a partnership (or any other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the ordinary shares or
ADSs, the tax consequences relating to an investment in the

216

ordinary shares or ADSs will depend in part upon the status of the partner and the activities of the partnership. Such a partner or partnership
should consult its tax advisor regarding the specific tax considerations of acquiring, owning and disposing of the ordinary shares or ADSs in its
particular circumstances.

Persons  considering  an  investment  in  the  ordinary  shares  or  ADSs  should  consult  their  own  tax  advisors  as  to  the  particular  tax
consequences  applicable  to  them  relating  to  the  acquisition,  ownership  and  disposition  of  the  ordinary  shares  or ADSs,  including  the
applicability of U.S. federal, state and local tax laws, French tax laws and other non-U.S. tax laws.

This  description  does  not  address  the  U.S.  federal  estate,  gift  or  alternative  minimum  tax  considerations,  the  Medicare  tax  on  net  investment
income or any U.S. state, local or non-U.S. tax considerations of the acquisition, ownership and disposition of the ordinary shares or ADSs.

This description is based on the U.S. Internal Revenue Code of 1986, as amended, or the Code, existing, proposed and temporary U.S. Treasury
Regulations promulgated thereunder and administrative and judicial interpretations thereof, in each case as of the date hereof. All the foregoing
is  subject  to  change,  which  change  could  apply  retroactively,  and  to  differing  interpretations,  all  of  which  could  affect  the  tax  considerations
described  below.  There  can  be  no  assurances  that  the  U.S.  Internal  Revenue  Service,  or  the  IRS,  will  not  take  a  position  concerning  the  tax
consequences of the acquisition, ownership and disposition of the ordinary shares or ADSs or that such a position would not be sustained by a
court. The Company has not obtained, nor does the Company intend to obtain, a ruling with respect to the U.S. federal income tax considerations
of the purchase, ownership or disposition of its ordinary shares or ADSs. Accordingly, holders should consult their own tax advisors concerning
the U.S. federal, state, local and non-U.S. tax consequences of acquiring, owning and disposing of the ordinary shares or ADSs in their particular
circumstances.

As  indicated  below,  this  summary  is  subject  to  the  discussion  below  of  the  U.S.  federal  income  tax  rules  applicable  to  a  “passive  foreign
investment company” (PFIC).

In general, and taking into account the earlier assumptions, for U.S. federal income tax purposes, a U.S. holder holding ADSs will be treated as
the owner of the ordinary shares represented by the ADSs. Exchanges of ordinary shares for ADSs, and ADSs for ordinary shares, generally will
not be subject to U.S. federal income tax.

Distributions.  Subject  to  the  discussion  under  “—Passive  Foreign  Investment  Company  Considerations,”  below,  the  gross  amount  of  any
distribution (including any amounts withheld in respect of foreign tax) actually or constructively received by a U.S. holder with respect to the
ordinary shares or ADSs will generally be taxable to the U.S. holder as a dividend to the extent of the U.S. holder’s pro rata share of the current
or accumulated earnings and profits as determined under U.S. federal income tax principles. Distributions in excess of earnings and profits will
generally be non-taxable to the U.S. holder to the extent of, and will be applied against and reduce, the U.S. holder’s adjusted tax basis in the
ordinary shares or ADSs. Distributions in excess of earnings and profits and such adjusted tax basis will generally be taxable to the U.S. holder
as either long-term or short-term capital gain depending upon whether the U.S. holder has held the ordinary shares or ADSs for more than one
year  as  of  the  time  such  distribution  is  received.  However,  since  the  Company  does  not  calculate  its  earnings  and  profits  under  U.S.  federal
income tax principles, it is expected that any distribution will be reported as a dividend, even if that distribution would otherwise be treated as a
non-taxable return of capital or as capital gain under the rules described above. Non-corporate U.S. holders may qualify for the preferential rates
of taxation with respect to dividends on the ordinary shares or ADSs applicable to long-term capital gains (i.e., gains from the sale of capital
assets held for more than one year), or qualified dividend income if the Company is a

217

“qualified foreign corporation” and certain other requirements are met. A non-U.S. corporation (other than a corporation that is a PFIC for the
taxable year in which the dividend is paid or the preceding taxable year) generally will be considered to be a qualified foreign corporation (a) if it
is eligible for the benefits of a comprehensive tax treaty with the United States which the Secretary of Treasury of the United States determines is
satisfactory for purposes of this provision and which includes an exchange of information provision, or (b) with respect to any dividend it pays
on ADSs which are readily tradable on an established securities market in the United States. The ADSs are listed on the Nasdaq Global Select
Market, which is an established securities market in the United States, and the Company believes the ADSs are readily tradable on the Nasdaq
Global  Select  Market.  There  can  be  no  assurance  that  the ADSs  will  continue  to  be  considered  readily  tradable  on  an  established  securities
market in the United States in later years. The Company, which is incorporated under the laws of France, believes that it qualifies as a resident of
France for purposes of, and is eligible for the benefits of, the U.S.-France Tax Treaty (as defined below), although there can be no assurance in
this regard. Further, the IRS has determined that the U.S.-France Tax Treaty is satisfactory for purposes of the qualified dividend rules and that it
includes  an  exchange-of-information  program.  Therefore,  subject  to  the  discussion  under  “—Passive  Foreign  Investment  Company
Considerations,” below, such dividends will generally be “qualified dividend income” in the hands of individual U.S. holders, provided that a
holding period requirement (more than 60 days of ownership, without protection from the risk of loss, during the 121-day period beginning 60
days before the ex-dividend date) and certain other requirements are met. The dividends will not be eligible for the dividends-received deduction
generally allowed to corporate U.S. holders.

Subject to applicable limitations and the Foreign Tax Credit Regulations (as defined below), a U.S. holder generally may claim the amount of
any French withholding tax on a distribution not exceeding the rate provided by the U.S.-France Tax Treaty as either a deduction from gross
income or a credit against its U.S. federal income tax liability. French taxes withheld in excess of the rate applicable with respect to such U.S.
holder under the U.S.-France Tax Treaty will not be eligible for a credit against a U.S. holder’s federal income tax liability. U.S. holders should
consult  their  tax  advisors  regarding  the  availability  of  foreign  tax  credits  for  any  amounts  withheld  with  respect  to  dividends  on  ADSs  or
ordinary shares.

The  foreign  tax  credit  is  subject  to  numerous  complex  limitations  that  must  be  determined  and  applied  on  an  individual  basis.  Generally,  the
credit cannot exceed the proportionate share of a U.S. holder’s U.S. federal income tax liability that such U.S. holder’s taxable income bears to
such U.S. holder’s worldwide taxable income. In applying this limitation, dividends received generally will be treated as income from foreign
sources and generally will be “passive category income,” or in certain cases “general category income” or “foreign branch income,” which is
treated  separately  from  other  types  of  income  for  purposes  of  computing  the  foreign  tax  credit  allowable  to  U.S.  holders.  In  addition,  the
creditability  of  foreign  taxes  could  be  affected  by  actions  taken  by  intermediaries  in  the  chain  of  ownership  between  the  holders  of ADSs  or
ordinary shares and the Company if, as a result of such actions, the holders of our ADSs or ordinary shares are not properly treated as beneficial
owners  of  the  underlying  ordinary  shares.  Further,  certain  Treasury  regulations  addressing  foreign  tax  credits  (the  “Foreign  Tax  Credit
Regulations”) impose additional requirements for foreign taxes to be eligible for a foreign tax credit if the relevant taxpayer does not elect to
apply the benefits of an applicable income tax treaty, and there can be no assurance that those requirements will be satisfied. Recent notices from
the IRS provide temporary relief by allowing taxpayers that comply with applicable requirements to apply many aspects of the foreign tax credit
regulations as they previously existed (before the release of the current Foreign Tax Credit Regulations) for taxable years ending before the date
that  a  notice  or  other  guidance  withdrawing  or  modifying  the  temporary  relief  is  issued  (or  any  later  date  specified  in  such  notice  or  other
guidance). Each U.S. holder should consult its own tax advisors regarding the foreign tax credit rules, including under the Foreign Tax Credit
Regulations.

218

In general, the amount of a distribution paid to a U.S. holder in a foreign currency will be the U.S. dollar value of the foreign currency calculated
by reference to the spot exchange rate on the day the depositary receives the distribution, in the case of the ADSs, or on the day the distribution is
received by the U.S. holder, in the case of ordinary shares, regardless of whether the foreign currency is converted into U.S. dollars at that time.
Any foreign currency gain or loss a U.S. holder realizes on a subsequent conversion of foreign currency into U.S. dollars will be U.S. source
ordinary income or loss. If dividends received in a foreign currency are converted into U.S. dollars on the day they are received, a U.S. holder
should not be required to recognize foreign currency gain or loss in respect of the dividend.

Sale, Exchange or Other Taxable Disposition. A U.S. holder will generally recognize gain or loss for U.S. federal income tax purposes upon the
sale, exchange or other taxable disposition of the ordinary shares or ADSs in an amount equal to the difference between the amount realized from
such sale or exchange and the U.S. holder’s adjusted tax basis in those ordinary shares or ADSs, each as determined in U.S. dollars. U.S. holders
should consult their own tax advisors about how to account for proceeds received on the sale, exchange or other taxable disposition of ordinary
shares  or ADSs  that  are  not  paid  in  U.S.  dollars.  Subject  to  the  discussion  under  “—Passive  Foreign  Investment  Company  Considerations”
below, this gain or loss will generally be a capital gain or loss. The adjusted tax basis in the ordinary shares or ADSs generally will be equal to
the U.S. dollar cost of such ordinary shares or ADSs. Capital gain from the sale, exchange or other taxable disposition of the ordinary shares or
ADSs by a non-corporate U.S. holder is generally eligible for a preferential rate of taxation applicable to capital gains, if the non-corporate U.S.
holder’s holding period determined at the time of such sale, exchange or other taxable disposition for such ordinary shares or ADSs exceeds one
year (i.e., such gain is long-term taxable gain). The deductibility of capital losses for U.S. federal income tax purposes is subject to limitations.
Any such gain or loss that a U.S. holder recognizes generally will be treated as U.S. source gain or loss for foreign tax credit limitation purposes.

Passive Foreign Investment Company Considerations. If the Company is a PFIC in any taxable year, a U.S. holder will be subject to special
rules generally intended to reduce or eliminate any benefits from the deferral of U.S. federal income tax that a U.S. holder could derive from
investing in a non-U.S. company that does not distribute all of its earnings on a current basis.

The Company will be a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying certain look-through rules with
respect to the income and assets of its subsidiaries, either: (1) at least 75% of the gross income is “passive income” or (2) at least 50% of the
average quarterly value of the total gross assets (which would generally be measured by fair market value of its assets, and for which purpose the
total  value  of  its  assets  may  be  determined  in  part  by  the  market  value  of  the ADSs  and  its  ordinary  shares,  which  are  subject  to  change)  is
attributable to assets that produce “passive income” or are held for the production of “passive income.”

Passive income for this purpose generally includes dividends, interest, royalties, rents, gains from commodities and securities transactions, the
excess  of  gains  over  losses  from  the  disposition  of  assets  which  produce  passive  income,  and  includes  amounts  derived  by  reason  of  the
temporary investment of funds raised in offerings of the ordinary shares or ADSs. If a non-U.S. corporation owns directly or indirectly at least
25% by value of the stock of another corporation or entity treated as a partnership for U.S. federal income tax purposes, the non-U.S. corporation
is treated for purposes of the PFIC tests as owning its proportionate share of the assets of such entity and as receiving directly its proportionate
share of the other entity’s income. The determination of whether the Company is a PFIC is a fact-intensive determination made on an annual
basis, and the applicable law is subject to varying interpretation. If the Company is a PFIC in any taxable year during which a U.S. holder owns
its ordinary shares or ADSs,

219

such U.S. holder will be subject to special tax rules discussed below and could suffer adverse tax consequences.

The market value of the assets may be determined in large part by reference to the market price of the ADSs and its ordinary shares. Therefore,
fluctuations  in  the  market  price  of  the  ordinary  shares  or ADSs  may  result  in  the  Company  being  a  PFIC  for  any  taxable  year.  Whether  the
Company is a PFIC for any taxable year will depend on income, assets, activities and market capitalization in each year, and because this is a
factual determination made annually after the end of each taxable year, there can be no assurance that the Company will not be a PFIC in any
taxable year. The Company does not believe it was characterized as a PFIC in its taxable year ended December 31, 2024. However, there can be
no  assurance  that  the  Company  will  not  be  a  PFIC  in  the  current  year  or  for  any  future  taxable  year.  Its  U.S.  counsel  expresses  no  opinion
regarding its conclusions or its expectations regarding its PFIC status.

If the Company is a PFIC in any year with respect to which a U.S. holder owns its ordinary shares or ADSs, the Company will continue to be
treated  as  a  PFIC  with  respect  to  such  U.S.  holder  in  all  succeeding  years  during  which  the  U.S.  holder  owns  the  ordinary  shares  or ADSs,
regardless of whether the Company continue to meet the tests described above unless the Company ceases to be a PFIC and the U.S. holder has
made  a  “deemed  sale”  election  under  the  PFIC  rules  or  is  eligible  to  make  and  makes  a  mark-to-market  election  (as  described  below),  with
respect to all taxable years during such U.S. holder’s holding period in which the Company is a PFIC. If the “deemed sale” election is made, a
U.S.  holder  will  be  deemed  to  have  sold  the  ordinary  shares  or ADSs  the  U.S.  holder  holds  at  their  fair  market  value  as  of  the  date  of  such
deemed sale and any gain from such deemed sale would be subject to the rules described below. After the deemed sale election, so long as the
Company does not become a PFIC in a subsequent taxable year, the U.S. holder’s ordinary shares or ADSs with respect to which such election
was made will not be treated as shares in a PFIC and the U.S. holder will not be subject to the rules described below with respect to any “excess
distribution” the U.S. holder receives from the Company or any gain from an actual sale or other disposition of the ordinary shares or ADSs. U.S.
holders  should  consult  their  tax  advisors  as  to  the  possibility  and  consequences  of  making  a  deemed  sale  election  if  such  election  becomes
available.

If the Company is a PFIC, and you are a U.S. holder that does not make one of the elections described above (and below in further detail), a
special tax regime will apply to both (a) any “excess distribution” by the Company to you (generally, your ratable portion of distributions in any
year which are greater than 125% of the average annual distribution received by you in the shorter of the three preceding years or your holding
period  for  its  ordinary  shares  or ADSs)  and  (b)  any  gain  realized  on  the  sale  or  other  disposition  of  its  ordinary  shares  or ADSs.  Under  this
regime, any excess distribution and realized gain will be treated as ordinary income and will be subject to tax as if (a) the excess distribution or
gain had been realized ratably over your holding period for the ordinary shares or ADSs, (b) the amount deemed realized in each year had been
subject to tax in each year of that holding period at the highest marginal rate for such year (other than income allocated to the current period or
any taxable period before the Company became a PFIC, which would be subject to tax at the U.S. holder’s regular ordinary income rate for the
current year and would not be subject to the interest charge discussed below), and (c) the interest charge generally applicable to underpayments
of  tax  had  been  imposed  on  the  taxes  deemed  to  have  been  payable  in  those  years.  In  addition,  dividend  distributions  made  to  you  will  not
qualify for the lower rates of taxation applicable to qualified dividends discussed above under “Distributions.”

Certain elections may alleviate some of the adverse consequences of PFIC status and would result in an alternative treatment of the ordinary
shares or ADSs. If a U.S. holder makes a mark-to-market election, the U.S. holder generally will recognize as ordinary income any excess of the
fair market value of the ordinary shares or ADSs at the end of each taxable year over their adjusted tax basis, and will recognize an ordinary loss
in respect of any excess of the adjusted tax basis of the ordinary shares or ADSs over

220

their fair market value at the end of the taxable year (but only to the extent of the net amount of income previously included as a result of the
mark-to-market  election).  If  a  U.S.  holder  makes  the  election,  the  U.S.  holder’s  tax  basis  in  the  ordinary  shares  or ADSs  will  be  adjusted  to
reflect these income or loss amounts. Any gain recognized on the sale or other disposition of the ordinary shares or ADSs in a year in which the
Company is a PFIC will be treated as ordinary income and any loss will be treated as an ordinary loss (but only to the extent of the net amount of
income previously included as a result of the mark-to-market election). The mark-to-market election is available only if the Company is a PFIC
and  its  ordinary  shares  or ADSs  are  “regularly  traded”  on  a  “qualified  exchange.”  Its  ordinary  shares  or ADSs  will  be  treated  as  “regularly
traded” in any calendar year in which more than a de minimis quantity of its ordinary shares or ADSs are traded on a qualified exchange on at
least 15 days during each calendar quarter (subject to the rule that trades that have as one of their principal purposes the meeting of the trading
requirement  are  disregarded).  The  Nasdaq  Global  Select  Market  is  a  qualified  exchange  for  this  purpose  and,  consequently,  if  the ADSs  are
regularly traded, the mark-to-market election will be available to a U.S. holder. It should be noted that only the ADSs and not its ordinary shares
are listed on the Nasdaq Global Select Market. Consequently, its ordinary shares may not be marketable if Euronext Paris (where its ordinary
shares are listed) does not meet the applicable requirements. U.S. holders should consult their tax advisors regarding the availability of the mark-
to-market election for ordinary shares that are not represented by ADSs.

However, a mark-to-market election generally cannot be made for equity interests in any lower-tier PFICs that the Company owns, unless shares
of such lower-tier PFIC are themselves “marketable.” As a result, even if a U.S. holder validly makes a mark-to-market election with respect to
its ordinary shares or ADSs, the U.S. holder may continue to be subject to the PFIC rules (described above) with respect to its indirect interest in
any of its investments that are treated as an equity interest in a PFIC for U.S. federal income tax purposes. U.S. holders should consult their tax
advisors as to the availability and desirability of a mark-to-market election, as well as the impact of such election on interests in any lower-tier
PFICs.

The Company does not currently intend to provide the information necessary for U.S. holders to make a “qualified electing fund election” if the
Company is treated as a PFIC for any taxable year. U.S. holders should consult their tax advisors to determine whether this election would be
available and if so, what the consequences of the alternative treatments would be in their particular circumstances.

If the Company is a PFIC, the general tax treatment for U.S. holders described in this section would apply to indirect distributions and gains
deemed to be realized by U.S. holders in respect of any of its subsidiaries that also may be PFICs. U.S. holders should consult their tax advisors
regarding the application of the PFIC rules to the Company's subsidiaries.

If a U.S. holder owns its ordinary shares or ADSs during any taxable year in which the Company is a PFIC, the U.S. holder generally will be
required to file an IRS Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund)
with  respect  to  the  Company,  generally  with  the  U.S.  holder’s  federal  income  tax  return  for  that  year.  If  the  Company  is  a  PFIC  for  a  given
taxable year, then you should consult your tax advisor concerning your annual filing requirements.

The U.S. federal income tax rules relating to PFICs are complex. Prospective U.S. investors are urged to consult their own tax advisors
with respect to the acquisition, ownership and disposition of the ordinary shares or ADSs, the consequences to them of an investment in
a PFIC, any elections available with respect to the ordinary shares or ADSs and the IRS information reporting

221

obligations with respect to the acquisition, ownership and disposition of the ordinary shares or ADSs.

Backup Withholding and Information Reporting. U.S. holders generally will be subject to information reporting requirements with respect to
dividends on the ordinary shares or ADSs and on the proceeds from the sale, exchange or disposition of the ordinary shares or ADSs that are paid
within  the  United  States  or  through  U.S.-related  financial  intermediaries,  unless  the  U.S.  holder  is  an  “exempt  recipient.”  In  addition,  U.S.
holders may be subject to backup withholding on such payments, unless the U.S. holder provides a taxpayer identification number and a duly
executed  IRS  Form W-9  or  otherwise  establishes  an  exemption.  Backup  withholding  is  not  an  additional  tax,  and  the  amount  of  any  backup
withholding will be allowed as a credit against a U.S. holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided
that the required information is timely furnished to the IRS.

Foreign  Asset  Reporting.  Certain  individual  U.S.  holders  are  required  to  report  information  relating  to  an  interest  in  the  ordinary  shares  or
ADSs, subject to certain exceptions (including an exception for shares held in accounts maintained by U.S. financial institutions) by filing IRS
Form 8938 (Statement of Specified Foreign Financial Assets) with their federal income tax return. In addition, a U.S. holder should consider the
possible obligation to file online a FinCEN Form 114 - Foreign Bank and Financial Accounts Report as a result of holding shares or ADSs. U.S.
holders  are  urged  to  consult  their  tax  advisors  regarding  their  information  reporting  obligations,  if  any,  with  respect  to  their  ownership  and
disposition of the ordinary shares or ADSs.

THE DISCUSSION ABOVE IS A SUMMARY OF THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF AN INVESTMENT IN
THE ORDINARY SHARES OR ADSs AND IS BASED UPON LAWS AND RELEVANT INTERPRETATIONS THEREOF IN EFFECT
AS  OF  THE  DATE  OF  THIS  ANNUAL  REPORT,  ALL  OF  WHICH  ARE  SUBJECT  TO  CHANGE,  POSSIBLY  WITH
RETROACTIVE EFFECT. EACH PROSPECTIVE INVESTOR IS URGED TO CONSULT ITS OWN TAX ADVISOR ABOUT THE
TAX CONSEQUENCES TO IT OF AN INVESTMENT IN THE ORDINARY SHARES OR ADSs IN LIGHT OF THE INVESTOR’S
OWN CIRCUMSTANCES.

Material French Tax Considerations

The following describes the material French income tax consequences to U.S. holders of purchasing, owning and disposing of ordinary shares or
the ADSs.

This discussion does not purport to be a complete analysis or listing of all potential tax effects of the acquisition, ownership or disposition of our
ordinary shares or the ADSs to any particular investor, and does not discuss tax considerations that arise from rules of general application or that
are generally assumed to be known by investors. All of the following is subject to change. Such changes could apply retroactively and could
affect the consequences described below.

In particular, the French finance bill for 2025 (loi de finances pour 2025) enacted on February 14, 2025 contains certain measures that affect the
French taxation of U.S. holders purchasing, owning and disposing of ordinary shares or ADSs

This  summary  does  not  constitute  a  legal  opinion  or  tax  advice.  U.S.  holders  are  advised  to  consult  their  own  tax  advisors  regarding  the  tax
consequences  of  the  purchase,  ownership  and  disposition  of  ordinary  shares  or ADSs  in  light  of  their  particular  circumstances,  including  the
effect of any U.S. federal, state, local or other national tax laws.

French tax rules applicable to French assets that are held by or in foreign trusts generally provide inter alia for the inclusion of trust assets in the
settlor’s net assets for the purpose of applying the French real

222

estate wealth tax, for the application of French gift and estate tax to French assets held in trust, for a specific tax on capital on the French assets
of foreign trusts not already subject to the French real estate wealth tax and for a number of French tax reporting and disclosure obligations. The
following discussion does not address the French tax consequences applicable to securities (including ordinary shares or ADSs) held in trusts. If
our  ordinary  shares  or ADSs  are  held  in  trust,  the  grantor,  trustee  and  beneficiary  are  advised  to  consult  their  own  tax  advisor  regarding  the
specific tax consequences of acquiring, owning and disposing of such securities.

The description of the French income tax and real estate wealth tax consequences set forth below is based on the double tax treaty entered into
between the Government of the United States of America and the Government of the French Republic for the Avoidance of Double Taxation and
the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital of August 31, 1994 (the “U.S.-France Tax Treaty”), which came
into force on December 30, 1995 (as amended by any subsequent protocols, including the protocol of January 13, 2009), and the tax guidelines
issued by the French tax authorities in force as of the date of this Annual Report.

For the purposes of this discussion, the term “U.S. Holder” means a beneficial owner of securities that is (1) an individual who is a U.S. citizen
or resident for U.S. federal income tax purposes, (2) a U.S. domestic corporation or certain other entities created or organized in or under the
laws  of  the  United  States  or  any  state  thereof,  or  (3)  otherwise  subject  to  U.S.  federal  income  taxation  on  a  net  income  basis  in  respect  of
securities.

If  a  partnership  holds ADSs,  the  tax  treatment  of  the  partnership  and  a  partner  in  such  partnership  generally  will  depend  on  the  status  of  the
partner  and  the  activities  of  the  partnership.  Such  partner  or  partnership  is  urged  to  consult  its  own  tax  advisor  regarding  the  specific  tax
consequences of acquiring, owning and disposing of ADSs.

This discussion applies only to investors that hold ADSs as capital assets that are entitled to Treaty benefits under the “Limitation on Benefits”
provision  contained  in  the  U.S.-France  Tax  Treaty,  and  whose  ownership  of  the  ordinary  shares  or  ADSs  is  not  effectively  connected  to  a
permanent establishment or a fixed base in France. Certain U.S. Holders (including, but not limited to, U.S. expatriates, partnerships or other
entities classified as partnerships for U.S. federal income tax purposes, banks, insurance companies, regulated investment companies, tax-exempt
organizations, financial institutions, persons subject to the alternative minimum tax, persons who acquired the securities pursuant to the exercise
of employee share options or otherwise as compensation, persons that own (directly, indirectly or by attribution) 5% or more of our voting stock
or  5%  or  more  of  our  outstanding  share  capital,  dealers  in  securities  or  currencies,  brokers,  mutual  funds,  individual  retirement  or  other  tax-
deferred accounts persons that elect to mark their securities to market for U.S. federal income tax purposes and persons holding securities as a
position in a synthetic security, straddle or conversion transaction) may be subject to special rules not discussed below, and are advised to consult
their usual tax advisor regarding the specific tax consequences which may apply to their particular situation.

U.S. Holders are advised to consult their own tax advisor regarding the tax consequences of the purchase, ownership and disposition of securities
in  light  of  their  particular  circumstances,  especially  with  regard  to  the  “Limitations  on  Benefits”  provision  contained  in  the  U.S.-France  Tax
Treaty.

Tax on Sale or other Disposals

As a matter of principles, under French tax law subject to limited exemptions,and to the extent Innate is not a real estate company for the purpose
of Article 244 bis A of the French Tax Code (Code général des impôts, the “FTC”), a U.S. Holder should not be subject to any French tax on any
capital gain from the sale, exchange, repurchase or redemption by Innate of ordinary shares or ADSs, provided such U.S.

223

Holder  is  not  a  French  tax  resident  for  French  tax  purposes  and  has  not  held  more  than  25%  of  the  dividend  rights,  known  as  “droits  aux
bénéfices sociaux,” at any time during the preceding five years, either directly or indirectly, and, as relates to individuals, alone or with relatives
it has not transferred ordinary shares or ADSs as part of redemption by Innate, in which case the proceeds may under certain circumstances be
partially or fully characterized as dividends under French domestic law and, as result, be subject to French dividend withholding tax.

As an exception, a U.S. Holder resident established or incorporated in certain non-cooperative States or territories as defined in Article 238-0 A
of the FTC should be subject to a 75% withholding tax in France on any such capital gain, regardless of the fraction of the dividend rights it
holds, subject to safe-harbor provisions and the more favorable provisions of the U.S.-France Tax Treaty. The list of non-cooperative State or
territory  is  published  by  decree  and  is  in  principle  updated  annually.  This  list  was  last  updated  on  16  February  2024,  and  currently  includes
American Samoa, Anguilla, Antigua and Barbuda, the Bahamas, Belize, Fiji, Guam, Palaos, Panama, Russia, Samoa, Seychelles, Trinidad and
Tobago, Turk  and  Caicos,  the  United  States Virgin  Islands  and Vanuatu.  States  referred  to  in Article  238-0 A,  2  bis-2°  of  the  FTC,  and  thus
outside of the scope of Article 244 bis B of the FTC, are currently Antigua and Barbuda, Belize, Fiji, Guam, United States Virgin Islands, Palaos,
Panama, Russia, Samoa, American Samoa and Trinidad and Tobago.

Under application of the U.S.-France Tax Treaty, a U.S. Holder who is a U.S. resident for purposes of the U.S.-France Tax Treaty and entitled to
Treaty benefits will not be subject to French tax on such capital gain unless the ordinary shares or the ADSs form part of the business property of
a  permanent  establishment  or  fixed  base  that  the  U.S.  Holder  has  in  France.  U.S.  Holders  who  own  ordinary  shares  or ADSs  through  U.S.
partnerships that are not resident for U.S.-France Tax Treaty purposes are advised to consult their own tax advisor regarding their French tax
treatment and their eligibility for Treaty benefits in light of their own particular circumstances.

A  U.S.  Holder  that  is  not  a  U.S.  resident  for  U.S.-France  Tax  Treaty  purposes  or  is  not  entitled  to  Treaty  benefits  (and  in  both  cases  is  not
resident, established or incorporated in certain non-cooperative States or territories as defined in Article 238-0 A of the FTC) and has held more
than 25% of the dividend rights, known as “droits aux bénéfices sociaux” at any time during the preceding five years, either directly or indirectly,
and, as relates to individuals, alone or with relatives will be subject to a levy in France (i) at the rate of 12.8% for individuals, and (ii) 25% for
legal persons. However, eligible non-French tax resident legal entities may claim a refund of the 25% French levy to the extent such tax exceeds
the amount that would have been due under French corporate income tax if they had been French tax residents. This refund mechanism is only
available to certain legal entities. Non-French tax resident legal entities are advised to consult their own tax advisor regarding their French tax
treatment and their eligibility to this refund mechanism.

The above French provisions expressly apply to sale, repurchase or redemption by us of ordinary shares.

Special rules apply to U.S. Holders who are residents of more than one country.

Financial Transactions Tax

Pursuant to Article 235 ter ZD of the FTC, purchases of shares or ADSs of a French company listed on a regulated market of the European Union
or on a foreign regulated market formally acknowledged by the AMF, provided inter alia that the issuer's market capitalization exceeds €1 billion
as of December 1 of the year preceding the taxation year, are subject to a French tax on financial transactions at a 0.3% rate until March 31,
2025, and then at a 0.4% rate as from April 1, 2025 (pursuant to Article 98 of the finance bill for 2025).

224

A list of companies whose market capitalization exceeds 1 billion euros as of December 1 of the year preceding the taxation year, within the
meaning of Article 235 ter ZD of the FTC, is published annually by the French tax authorities in their official guidelines. As at December 1,
2024, the market capitalization did not exceed 1 billion euros, pursuant to BOI-ANNX-000467-23/12/2024 issued on December 23, 2024.

Moreover,  Nasdaq  Global  Select  Market,  on  which ADSs  are  listed,  is  not  currently  acknowledged  by  the AMF,  but  this  may  change  in  the
future.

As a consequence, neither the ADSs nor the ordinary shares are currently within the scope of the French tax on financial transactions.

Purchases of our securities may be subject to such tax in the future provided that the market capitalization exceeds 1 billion euros in the year
preceding the taxation year and that the Nasdaq Global Select Market is acknowledged by the French AMF.

Registration Duties

In the case where Article 235 ter ZD of the FTC is not applicable, transfers of shares issued by a French company which are listed on a regulated
or  organized  market  within  the  meaning  of  the  French  monetary  and  financial  code  ("Code  monétaire  et  financier")  are  subject  to  uncapped
registration duties at the rate of 0.1% if the transfer is evidenced by a written statement (“acte”) executed either in France or outside France. As
ordinary shares of the company are listed on Euronext Paris, which is an organized market within the meaning of the French monetary code,
their transfer should be subject to uncapped registration duties at the rate of 0.1% subject to the existence of a written statement (“acte”), and
provided that Article 235 ter ZD of the FTC is not applicable. Although there is no case law or official guidelines published by the French tax
authorities on this point, transfer of ADSs should remain outside of the scope of the aforementioned 0.1% registration duties. U.S. Holders are
urged to consult their own tax advisor about the possible application of the registration duty upon the transfer of ADSs.

Taxation of Dividends

Dividends  paid  by  a  French  corporation  to  non-residents  of  France  are  generally  subject  to  French  withholding  tax  at  a  rate  of  (i)  25%  for
payment benefiting legal persons who are beneficial owners and are not French tax residents (and 15% for distributions made to not-for-profit
organizations  with  a  head  office  in  a  Member  State  of  the  European  Economic Area  that  would  be  subject  to  the  tax  regime  set  forth  under
Article 206 paragraph 2 of the FTC if its head office were located in France and that meet the criteria set forth in the tax guidelines BOI-RPPM-
RCM-30-30-10-70-24/12/2019,  No.  130,  dated  December  24,  2019),  and  (ii)  12.8%  for  payment  benefiting  individuals  who  are  beneficial
owners and are not French tax residents. Dividends paid by a French corporation in certain non-cooperative States or territories, as defined in
Article  238-0  A  of  the  FTC,  will  generally  be  subject  to  French  withholding  tax  at  a  rate  of  75%,  irrespective  of  the  tax  residence  of  the
beneficiary of the dividends if the dividends are received in such States or territories. However, eligible U.S. Holders entitled to Treaty benefits
under  the  “Limitation  on  Benefits”  provision  contained  in  the  U.S.-France  Tax  Treaty  who  are  U.S.  residents,  as  defined  pursuant  to  the
provisions of the U.S.-France Tax Treaty, will not be subject to this 25% or 75% withholding tax rate, but may be subject to the withholding tax
at a reduced rate (as described below).

Under  the  U.S.-France Tax Treaty,  the  rate  of  French  withholding  tax  on  dividends  paid  to  an  eligible  U.S.  Holder  who  is  a  U.S.  resident  as
defined  pursuant  to  the  provisions  of  the  U.S.-France  Tax  Treaty  and  whose  ownership  of  the  ordinary  shares  or  ADSs  is  not  effectively
connected with a permanent establishment or fixed base that such U.S. Holder has in France, is generally reduced to 15%, or to 5% if such U.S.
Holder is a corporation and owns directly or indirectly at least 10% of the share capital of the

225

issuer; such U.S. Holder may claim a refund from the French tax authorities of the amount withheld in excess of the U.S.-France Tax Treaty rates
of 15% or 5%, if any.

For  U.S.  Holders  that  are  not  individuals  but  are  U.S.  residents,  as  defined  pursuant  to  the  provisions  of  the  U.S.-France  Tax  Treaty,  the
requirements for eligibility for Treaty benefits, including the reduced 5% or 15% withholding tax rates contained in the “Limitation on Benefits”
provision of the U.S.-France Tax Treaty, are complex, and certain technical changes were made to these requirements by the protocol of January
13, 2009. U.S. Holders are advised to consult their own tax advisor regarding their eligibility for Treaty benefits in light of their own particular
circumstances.

Dividends paid to an eligible U.S. Holder may immediately be subject to the reduced rates of 5% or 15% provided that:

•

•

such holder establishes before the date of payment that it is a U.S. resident under the U.S.-France Tax Treaty by completing and providing
the  depositary  with  a  treaty  form  (Form  5000)  in  accordance  with  French  guidelines  (BOI-INT-DG-20-20-20-20-12/09/2012  dated
September 12, 2012); or

the depositary or other financial institution managing the securities account in the U.S. of such holder provides the French paying agent
with a document listing certain information about the U.S. Holder and its ordinary shares or ADSs and a certificate whereby the financial
institution managing the U.S. Holder’s securities account in the United States takes full responsibility for the accuracy of the information
provided in the document.

Otherwise, dividends paid to a U.S. Holder, if such U.S. Holder is a legal person, will be subject to French withholding tax at the rate of 25%, or
75% if paid in certain non-cooperative States or territories (as defined in Article 238-0 A of the FTC), and then reduced at a later date to 5% or
15%, provided that such holder duly completes and provides the French tax authorities with the treaty forms Form 5000 and Form 5001 (due to
recent case law regarding status of limitation for filing a withholding tax claim; U.S. Holders are advised to consult their own tax advisors in this
respect).

Certain qualifying pension funds and certain other tax-exempt entities and certain U.S. residents may be subject to specific filing requirements.
They are advised to consult their own tax advisors on this point.

Form 5000 and Form 5001, together with instructions, will be provided by the depositary to all U.S. Holders registered with the depositary. The
depositary  will  arrange  for  the  filing  with  the  French  tax  authorities  of  all  such  forms  properly  completed  and  executed  by  U.S.  Holders  of
ordinary shares or ADSs and returned to the depositary in sufficient time so that they may be filed with the French tax authorities before the
distribution in order to immediately obtain a reduced withholding tax rate. Otherwise, the depositary must withhold tax at the full rate of 25% or
75% as applicable. In that case, the U.S. Holders may claim a refund from the French tax authorities of the excess withholding tax.

In  any  case,  individual  taxpayers  who  are  not  fiscally  domiciled  in  France  should  not  have  to  comply  with  these  procedures  if  the  French
withholding tax applying to them is lower than 15%.

In particular, since the withholding tax rate applicable under French domestic law to U.S. Holders who are individuals does not exceed the cap
provided in the U.S.-France Tax Treaty (i.e., 15%), the 12.8% rate shall apply, without any reduction provided under the U.S.-France Tax Treaty
(except  in  the  particular  situation  when  the  dividends  are  paid  to  such  U.S.  Holders  out  of  France  in  a  non-cooperative  State  or  territory  as
defined in Article 238-0 A of the FTC other than those mentioned in 2° of 2 bis of the same Article 238-0 A of the FTC and are subject to the
75% withholding tax in France).

226

Besides, please note that pursuant to Article 235 quater of the FTC (introduced by the French finance bill No. 2019-1479 for 2020) and under
certain  conditions  (in  particular,  in  addition  to  certain  reporting  obligations,  the  interest  held  in  the  distributing  company  must  not  enable  the
beneficiary to participate effectively in the management or control of that company and the beneficiary company is located in a country that has
signed  an  administrative  assistance  agreement  with  France  to  combat  tax  evasion  and  avoidance,  as  well  as  an  administrative  assistance
agreement on tax collection, and that is not a non-cooperative country), a corporate U.S. Holder which is in a tax loss position or which tax result
is  nil  due  to  offset  of  tax  losses  (French Administrative  Supreme  Court,  October  18,  2022,  n°  466329)  for  the  fiscal  year  during  which  the
dividend  is  received  may  be  entitled  to  a  deferral  regime,  and  obtain  a  withholding  tax  refund.  The  tax  deferral  ends  in  respect  of  the  first
financial year during which this U.S. Holder is in a profit-making position, as well as in the cases set out in Article 235 quater of the FTC. The
refund must be claimed within the same period applicable to claim related to taxes other than local taxes. Also, pursuant to Article 235 quinquies
of  the  FTC  and  under  certain  conditions,  a  corporate  U.S.  Holder  may  be  entitled  to  a  refund  of  a  fraction  of  the  withholding  tax,  up  to  the
difference between the withholding tax paid (on a gross basis) and the withholding tax based on the dividend net of the expenses incurred for the
acquisition and conservation directly related to the income, provided (i) that these expenses would have been tax deductible had the U.S. Holder
been established in France, and (ii) that the tax rules in the United States do not allow the U.S. Holder to offset the withholding tax.

Given the special features of the ADSs, U.S. Holders are advised to consult their own tax advisor about the possible application to ADSs of such
provisions in light of their own circumstances.

Estate and Gift Taxes

In general, a transfer of securities by gift or by reason of death of a U.S. Holder that would otherwise be subject to French gift or inheritance tax,
respectively, will not be subject to such French tax by reason of the double tax treaty entered into between the Government of the United States
of America and the Government of the French Republic for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect
to Taxes on Estates, Inheritances and Gifts, dated November 24, 1978 (as amended from time to time), unless (i) the donor or the transferor is
domiciled in France at the time of making the gift or at the time of his or her death, or (ii) the securities were used in, or held for use in, the
conduct of a business through a permanent establishment or a fixed base in France.

Real Estate Wealth Tax

As from January 1, 2018, the French wealth tax (impôt de solidarité sur la fortune) is repealed and replaced by the French real estate wealth tax
(impôt sur la fortune immobilière or IFI). The scope of such new tax is narrowed to French real estate assets (and certain assets deemed to be real
estate assets) or rights, held directly or indirectly through one or more legal entities and whose net taxable assets amount at least to €1,300,000.

Broadly, subject to provisions of double tax treaties and to certain exceptions, individuals who are not residents of France for tax purposes within
the  meaning  of Article  4  B  of  the  FTC  are  subject  to  the  IFI  in  France  in  respect  of  the  portion  of  the  value  of  their  shares  of  the  company
representing real estate assets (Article 965, 2° of the FTC). Some exceptions are provided by the FTC. In particular, Innate’s ordinary shares or
ADSs  owned  by  a  U.S.  Holder  should  not  fall  within  the  scope  of  the  IFI  provided  that  such  U.S.  Holder  does  not  own  (together  with  the
members  of  his/her  household)  directly  or  indirectly  a  shareholding  exceeding  10%  of  the  financial  rights  and  voting  rights  of  Innate.  U.S.
Holders holding directly or indirectly a shareholding exceeding 10% of the financial rights and voting rights of Innate should seek additional
advice.

227

Under the U.S.-France Tax Treaty (the provisions of which should be applicable to this IFI in France), the IFI will however generally not apply
to securities held by an eligible U.S. Holder who is a U.S. resident, as defined pursuant to the provisions of the U.S.-France Tax Treaty, provided
that such U.S. Holder (i) does not own directly or indirectly more than 25% of the issuer’s financial rights and (ii) that the ADSs do not form part
of the business property of a permanent establishment or fixed base in France.

U.S. Holders are advised to consult their own tax advisor regarding the specific tax consequences which may apply to their particular situation
with respect to such IFI.

The Company is subject to the information reporting requirements of the U.S. Securities Exchange Act of 1934, as amended, (the “Exchange
Act”) applicable to foreign private issuers and under those requirements will file reports with the SEC. Those reports may be inspected without
charge at the locations described below. As a foreign private issuer, the Company is exempt from the rules under the Exchange Act related to the
furnishing and content of proxy statements, and its officers, directors and principal shareholders are exempt from the reporting and short-swing
profit recovery provisions contained in Section 16 of the Exchange Act. In addition, the Company is not required under the Exchange Act to file
periodic reports and financial statements with the SEC as frequently or as promptly as United States companies whose securities are registered
under the Exchange Act. Nevertheless, the Company will file with the SEC an Annual Report on Form 20-F containing financial statements that
have been examined and reported on, with an opinion expressed by an independent registered public accounting firm.

The Company maintains a corporate website at www.innate-pharma.com. The Company intends to post its Annual Report on Form 20-F on its
website  promptly  following  it  being  filed  with  the  SEC.  Information  contained  on,  or  that  can  be  accessed  through,  its  website  does  not
constitute  a  part  of  this  Annual  Report.  The  Company  has  included  its  website  address  in  this  Annual  Report  solely  as  an  inactive  textual
reference.

The Securities and Exchange Commission maintains a website (www.sec.gov) that contains reports, proxy and information statements and other
information regarding registrants, such as us, that file electronically with the SEC.

Item 11. Quantitative and Qualitative Disclosures About Market Risk.

The Company's activities are exposed to liquidity risk, foreign currency exchange risk, interest rate risk and credit risk.

Liquidity risk

The  Company  does  not  believe  that  it  is  exposed  to  short-term  liquidity  risk,  considering  its  cash  and  cash  equivalents  and  short-term
investments  of  €80.8  million  as  of  December  31,  2024,  which  consist  primarily  of  cash  and  money  market  funds  and  term  deposits,  are
convertible into cash immediately without penalty.

Foreign currency exchange rate risk

The  Company  is  exposed  to  foreign  exchange  risk  inherent  in  certain  subcontracting  activities  related  to  its  operations  in  the  United  States,
which are invoiced in U.S. dollars. The Company does not currently have material recurring revenues in euro, dollars or in any other currency.
As the Company further increases its business, particularly in the United States, the Company expects to face greater exposure to exchange rate
risk.

Innate's revenue denominated in U.S. dollars has represented approximately 92%, 29% and 52% of revenue in the years ended December 31,
2022, 2023 and 2024, respectively. Payments in U.S. dollars represented approximately 50%, 43%, and 35% of the payments in the years ended
December 31, 2022, 2023 and 2024, respectively. In order to cover this foreign currency exchange rate risk, the Company kept in U.S. dollars a
part of the consideration received from AstraZeneca in June 2015, January 2019 and September 2020. The Company kept the entire U.S dollars
portion  of  the  proceeds  received  from  its  October  2019  global  offering  in  U.S  dollars. The  Company  does  not  use  hedging  instruments  in  its
current operations. Refer to Item 3.D. Risk Factors - Innate's business may be exposed to foreign exchange risks.

Interest rate risk

The Company has limited exposure to interest rate risk. Its exposure primarily relates to money market funds and time deposit accounts. Changes
in interest rates have a direct impact on the rate of return on these investments and the cash flows generated. The Company does not have any
credit facilities bearing variable interest rates. The repayment of the advances from Bpifrance, the borrowings subscribed in 2017 and the two
State  Guaranteed  Loans  obtained  in  2021  and  extended  in  2022,  are  not  subject  to  interest  rate  risk. The  effect  of  an  increase  or  decrease  in
interest rates would have an immaterial effect on profit or loss.

Credit risk

The credit risk related to the cash equivalents, short-term investments and non-current financial assets is not significant in light of the quality of
the issuers. The Company deemed that no instrument of its portfolio is exposed to credit risk.

D. American Depositary Shares.

Citibank, N.A. ("Citibank") acts as the depositary bank for the ADSs. Citibank’s depositary offices are located at 388 Greenwich Street, New
York, New York 10013. ADSs represent ownership interests in securities that are on deposit with the depositary bank. ADSs may be represented
by  certificates  that  are  commonly  known  as American  Depositary  Receipts  (ADRs).  Each ADS  represents  one  ordinary  share  (or  the  right  to
receive one ordinary share). The depositary bank typically appoints a custodian to safekeep the securities on deposit. In this case, the custodian is
Citibank Europe plc, 1 North Wall Quay, Dublin 1, Ireland.

The Company has appointed Citibank, N.A. as depositary bank pursuant to a deposit agreement. A copy of the deposit agreement has been filed
with  the  SEC  under  cover  of  a  Registration  Statement  on  Form  F-6  (Registration  No.  333-234063).  You  may  obtain  a  copy  of  the  deposit
agreement from the SEC’s website at www.sec.gov.

For  additional  information  on  our  ADSs,  please  refer  to  Exhibit  2.3  “Description  of  Securities  Other  than  Equity  Securities  –  American
Depositary Shares” of this Annual Report.

depositary bank:

upon a change in the ADSs-to-ordinary shares ratio, or for any other reason),
excluding ADS issuances as a result of distributions of ordinary shares)

Up to U.S. 5¢ per ADS issued

Fees

Cancellation of ADSs (e.g., a cancellation of ADSs for delivery of deposited
property, upon a change in the ADSs-to-ordinary shares ratio, or for any other
reason)

Up to U.S. 5¢ per ADS cancelled

Distribution of cash dividends or other cash distributions (e.g., upon a sale of
rights and other entitlements)

Up to U.S. 5¢ per ADS held on the applicable record date(s) established by the

and vice versa, or for any other reason)

Conversion of ADSs of one series for ADSs of another series (e.g.,
upon conversion of Partial Entitlement ADSs for Full Entitlement
ADSs, or upon conversion of Restricted ADSs (each as defined in the
Deposit Agreement) into freely transferable ADSs, and vice versa).

ADS holders are responsible to pay certain charges such as:

Up to U.S. 5¢ per ADS (or fraction thereof) transferred

Up to U.S. 5¢ per ADS (or fraction thereof) converted

•

•

taxes (including applicable interest and penalties) and other governmental charges;

the registration fees as may from time to time be in effect for the registration of ordinary shares on the share register and applicable to
transfers of ordinary shares to or from the name of the

231

custodian, the depositary bank or any nominees upon the making of deposits and withdrawals, respectively;

certain cable, telex and facsimile transmission and delivery expenses;

the fees, expenses, spreads, taxes and other charges of the depositary bank and/or service providers (which may be a division, branch or
affiliate of the depositary bank) in the conversion of foreign currency;

the  reasonable  and  customary  out-of-pocket  expenses  incurred  by  the  depositary  bank  in  connection  with  compliance  with  exchange
control regulations and other regulatory requirements applicable to ordinary shares, ADSs and ADRs; and

•

•

•

•

ADS fees and charges for (i) the issuance of ADSs, and (ii) the cancellation of ADSs are charged to the person for whom the ADSs are issued (in
the case of ADS issuances) and to the person for whom ADSs are cancelled (in the case of ADS cancellations). In the case of ADSs issued by the
depositary bank into DTC, the ADS issuance and cancellation fees and charges may be deducted from distributions made through DTC, and may
be charged to the DTC participant(s) receiving the ADSs being issued or the DTC participant(s) holding the ADSs being cancelled, as the case
may be, on behalf of the beneficial owner(s) and will be charged by the DTC participant(s) to the account of the applicable beneficial owner(s) in
accordance with the procedures and practices of the DTC participants as in effect at the time. ADS fees and charges in respect of distributions
and the ADS service fee are charged to the holders as of the applicable ADS record date. In the case of distributions of cash, the amount of the
applicable ADS fees and charges is deducted from the funds being distributed. In the case of (i) distributions other than cash and (ii) the ADS
service fee, holders as of the ADS record date will be invoiced for the amount of the ADS fees and charges and such ADS fees and charges may
be deducted from distributions made to holders of ADSs. For ADSs held through DTC, the ADS fees and charges for distributions other than
cash and the ADS service fee may be deducted from distributions made through DTC, and may be charged to the DTC participants in accordance
with the procedures and practices prescribed by DTC and the DTC participants in turn charge the amount of such ADS fees and charges to the
beneficial owners for whom they hold ADSs. In the case of (i) registration of ADS transfers, the ADS transfer fee will be payable by the ADS
Holder  whose ADSs  are  being  transferred  or  by  the  person  to  whom  the ADSs  are  transferred,  and  (ii)  conversion  of ADSs  of  one  series  for
ADSs  of  another  series,  the  ADS  conversion  fee  will  be  payable  by  the  Holder  whose  ADSs  are  converted  or  by  the  person  to  whom  the
converted ADSs are delivered.

In the event of refusal to pay the depositary bank fees, the depositary bank may, under the terms of the deposit agreement, refuse the requested
service until payment is received or may set off the amount of the depositary bank fees from any distribution to be made to the ADS holder. Note
that the fees and charges you may be required to pay may vary over time and may be changed by Innate and by the depositary bank. You will
receive prior notice of such changes. The depositary bank may reimburse Innate for certain expenses incurred by Innate Pharma in respect of the
ADR  program,  by  making  available  a  portion  of  the ADS  fees  charged  in  respect  of  the ADR  program  or  otherwise,  upon  such  terms  and
conditions as the Company and the depositary bank agree from time to time.

Payment of Taxes

ADS holders are responsible for the taxes and other governmental charges payable on the ADSs and the securities represented by the ADSs. We,
the depositary bank and the custodian may deduct from any

232

distribution  the  taxes  and  governmental  charges  payable  by  holders  and  may  sell  any  and  all  property  on  deposit  to  pay  the  taxes  and
governmental charges payable by holders. You are liable for any deficiency if the sale proceeds do not cover the taxes that are due.

The depositary bank may refuse to issue ADSs, to deliver, transfer, split and combine ADRs or to release securities on deposit until all taxes and
charges are paid by the applicable holder. The depositary bank and the custodian may take reasonable administrative actions to obtain tax refunds
and reduced tax withholding for any distributions on your behalf. However, you may be required to provide to the depositary bank and to the
custodian proof of taxpayer status and residence and such other information as the depositary bank and the custodian may require to fulfill legal
obligations. You are required to indemnify us, the depositary bank and the custodian for any claims with respect to taxes based on any tax benefit
obtained for you.

Item 15. Controls and Procedures.

Disclosure Controls and Procedures

The management, with the participation of the Chief Executive Officer (principal executive officer) and the Chief Financial Officer (principal
financial officer), after evaluating the effectiveness of the disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and
15d-15(e)), as of December 31, 2024, have concluded that, the disclosure controls and procedures were effective as of December 31, 2024.

Management’s Annual Report on Internal Control over Financial Reporting

The management is responsible for establishing and maintaining adequate internal controls over financial reporting, as such term is defined in
Exchange Act Rule 13a-15(f) and 15d-15(f) for the assessment of the effectiveness of our internal control over financial reporting. Because of its
inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements. Also,  projections  of  any  evaluation  of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

Under  the  supervision  and  with  the  participation  of  the  Chief  Executive  Officer  (principal  executive  officer)  and  the  Chief  Financial  Officer
(principal  financial  officer),  the  management  conducted  an  evaluation  of  internal  control  over  financial  reporting  based  upon  the  criteria
established  in  internal  Control  —  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway
Commission (COSO).

Based on that evaluation under these criteria, the management concluded that, as of December 31, 2024, the Company's internal control over
financial reporting was effective to provide reasonable assurance

233

regarding the reliability of its financial reporting and the preparation of its financial statements for external purposes, in accordance with IFRS
Accounting Standards (IFRS) principles.

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatements, and can only provide reasonable
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements.  Also,  projections  of  any  evaluation  of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

Remediation of Previously Identified Material Weakness in Internal Control over Financial Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable
possibility that a material misstatement of the financial statements will not be prevented or detected on a timely basis.

As previously disclosed in “Item 15 - Controls and Procedures” of our Annual Report on Form 20-F for the year ended December 31, 2023,
management concluded that, as of December 31, 2023, the Company’s internal control over financial reporting was effective.

Attestation Report of the Registered Public Accounting Firm

Because  the  Company  does  not  qualify  as  an  emerging  growth  company  as  defined  in  Section  2(a)  of  the  Securities Act,  as  modified  by  the
Jumpstart Our Business Startups Act of 2012 (the JOBS Act) since December 31, 2024, this Annual Report includes an attestation report of our
registered public accounting firms provided below.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMS

To the shareholders and the Board of Directors of Innate Pharma S.A.

Opinion on Internal Control over Financial Reporting

We  have  audited  the  internal  control  over  financial  reporting  of  Innate  Pharma  S.A.  and  its  subsidiary  (the  “Company”)  as  of  December  31,
2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of
the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial
reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013) issued by the COSO.

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)  (PCAOB),
consolidated  statements  of  financial  position  of  the  Company  as  of  December  31,  2024,  the  related  consolidated  statements  of  income  (loss),
comprehensive income (loss), changes in shareholders’ equity and cash flows for the year ended December 31, 2024 and our report dated April
30, 2025, expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The  Company’s  management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its  assessment  of  the
effectiveness of internal control over financial reporting, included in the accompanying “Management’s Annual Report on Internal Control over
Financial Reporting”. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.
We are public accounting firms registered with the PCAOB and are required to be independent with respect to the Company in accordance with
the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

234

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating
the  design  and  operating  effectiveness  of  internal  control  based  on  the  assessed  risk,  and  performing  such  other  procedures  as  we  considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  generally  accepted  accounting  principles.  A
company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance
that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting
principles,  and  that  receipts  and  expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and
directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that
the degree of compliance with the policies or procedures may deteriorate.

Paris la Défense, France and Neuilly-sur-Seine, France April 30, 2025

Deloitte & Associés and PricewaterhouseCoopers Audit have served as the Company’s auditor since 2014 and 2024, respectively.

Changes in Internal Control over Financial Reporting

are reasonably likely to materially affect, the internal control over financial reporting.

Audit and Non-Audit Services Pre-Approval Policy

The Audit Committee has responsibility for appointing, setting compensation of and overseeing the work of the independent registered public
accounting  firm.  In  recognition  of  this  responsibility,  the Audit  Committee  has  adopted  a  policy  governing  the  pre-approval  of  all  audit  and
permitted non-audit services performed by the independent registered public accounting firm to ensure that the provision of such services does
not impair the independent registered public accounting firm’s independence from Innate and the management. Unless a type of service to be
provided by the independent registered public accounting firm has received general pre-approval from the Audit Committee, it requires specific
pre-approval  by  the  Audit  Committee.  The  payment  for  any  proposed  services  in  excess  of  pre-approved  cost  levels  requires  specific  pre-
approval by the Audit Committee.

Pursuant  to  its  pre-approval  policy,  the Audit  Committee  may  delegate  its  authority  to  pre-approve  services  to  the  chairperson  of  the Audit
Committee. The decisions of the chairperson to grant pre-approvals must be presented to the full Audit Committee at its next scheduled meeting.
The Audit Committee may not delegate its responsibilities to pre-approve services to the management.

236

The Audit Committee has considered the non-audit services provided by Deloitte & Associés and PricewaterhouseCoopers Audit as described
above and believes that they are compatible with maintaining Deloitte & Associés’s and PricewaterhouseCoopers Audit's independence as the
independent registered public accounting firms.

Item 16F. Change in Registrant’s Certifying Accountant.

The  term  of  office  of  Odycé  Nexia  SAS,  former  joint  principal  statutory  auditor  of  the  Company,  expired  following  the  general  meeting  of
shareholders of May 23, 2024. The report of Odycé Nexia SAS on the consolidated financial statements for each of the years ended December
31, 2023 and 2022 was conducted for French law purposes only. Odycé Nexia SAS is not a public accounting firm registered with the Public
Company Accounting Oversight Board (United States) (PCAOB), and therefore did not conduct its audits in accordance with the standards of the
PCAOB and was not engaged as the principal accountant to audit the registrant’s financial statements for such purposes.

The general meeting of shareholders appointed PricewaterhouseCoopers Audit as new Statutory Auditor to replace Odycé Nexia SAS, and to act
as joint principal statutory auditor to audit the Company’s financial statements in accordance with the standards of the PCAOB. Consequently,
the  Supervisory  Board  proposed  to  the  general  meeting  of  shareholders  of  May  23,  2024  to  appoint  PricewaterhouseCoopers Audit  as  joint
principal statutory auditor for a 6-year term, i.e. until the general meeting of shareholders to be held in 2030, which will approve the financial
statements for the year 2029.

Furthermore,  for  the  years  ending  on  December  31,  2022  and  2023  and  the  subsequent  interim  period  through  May  23,  2024,  we  had  not
consulted  with  PricewaterhouseCoopers  Audit  regarding  either  (1)  the  application  of  accounting  principles  to  a  specified  transaction,  either
completed or proposed, or the type of audit opinion that might be rendered with respect to our consolidated financial statements, and neither a
written report was provided to Innate Pharma or oral advice was provided that PricewaterhouseCoopers Audit concluded was an important factor
considered by Innate Pharma in reaching a decision as to the accounting, auditing or financial reporting issue; or (2) any matter that was the
subject of a disagreement or a reportable event.

The  selection  procedure  of  PricewaterhouseCoopers Audit  was  overseen  by  the Audit  Committee,  following  which  a  recommendation  to  the
Supervisory Board was issued.

Item 16G. Corporate Governance.

As  a  French  société  anonyme,  the  Company  is  subject  to  various  corporate  governance  requirements  under  French  law.  The  Company  is  a
“foreign  private  issuer”  under  the  U.S.  federal  securities  laws  and  the  Nasdaq  listing  rules. As  a  foreign  private  issuer  listed  on  the  Nasdaq
Global Market, we will be subject to Nasdaq's corporate governance listing rules. However, the Nasdaq Global Market’s listing rules provide that
foreign private issuers, as defined in the rules promulgated under the U.S. Securities

237

Exchange Act of 1934, as amended (the "Exchange Act"), are permitted to follow home country corporate governance practices instead of certain
Nasdaq listing rules, with certain exceptions. A foreign private issuer that elects to follow a home country practice instead of Nasdaq's listing
rules must submit to Nasdaq a written statement from an independent counsel in such issuer’s home country certifying that the issuer’s practices
are not prohibited by the home country’s laws.

As a general matter, the Company follows the French Middlenext corporate governance code for corporate governance matters and it intends to
follow home country practice to the maximum extent possible.

Certain corporate governance practices in France may differ significantly from Nasdaq’s corporate governance listing standards. For example,
while Nasdaq Listing Rule 5605(b) would require a majority of the Supervisory Board to be independent, neither the corporate laws of France,
nor the Middlenext corporate governance code nor the Company's bylaws require that (i) a majority of the members of our Supervisory Board be
independent or (ii) the independent members of the Supervisory Board hold regularly scheduled meetings at which only independent members of
the  Supervisory  Board  are  present.  However,  the  Middlenext  code  recommends  that  at  least  two  members  of  the  Supervisory  Board  be
independent (as such term is defined under the code). Currently, all of the members of the Company’s Supervisory Board are independent and
therefore the Supervisory Board meets both the Middlenext requirement and the Nasdaq requirement for independence; however, in the future
the  Board  composition  could  change  such  that  the  Company  only  meets  the  Middlenext  requirement,  but  not  the  Nasdaq  requirement  for
independence.

Moreover, in accordance with French law, each of the committees of our Supervisory Board will only have an advisory role and can only make
recommendations  to  our  Supervisory  Board.  As  a  result,  decisions  will  be  made  by  our  Supervisory  Board  taking  into  account  nonbinding
recommendations of the relevant Supervisory Board committee.

With respect to the Audit Committee, as a foreign private issuer, the Sarbanes-Oxley Act of 2002 and the Nasdaq listing rules require that our
Audit Committee be composed of at least three independent members. Rule 10A-3 under the Exchange Act provides that the Audit Committee
must  have  direct  responsibility  for  the  nomination,  compensation  and  choice  of  the  auditors,  as  well  as  control  over  the  performance  of  their
duties, management of complaints made, and selection of consultants. Under Rule 10A-3, if the laws of a foreign private issuer’s home country
require that any such matter be approved by our Supervisory Board or the shareholders of the Company, the Audit Committee’s responsibilities
or powers with respect to such matter may instead be advisory. Under French law, the Audit Committee may only have an advisory role and
appointment of the statutory auditors, in particular, must be decided by the shareholders at the annual meeting.

In addition, Nasdaq listing rules require that a listed company specify that the quorum for any meeting of the holders of share capital be at least
33 1/3% of the outstanding shares of the company’s ordinary voting shares. The Company follows its French home country practice, rather than
complying with this Nasdaq listing rule. Consistent with French law, the Company's bylaws provide that when first convened, general meetings
of shareholders may validly convene only if the shareholders present or represented hold at least (1) 20% of the voting shares in the case of an
ordinary general meeting or of an extraordinary general meeting where shareholders are voting on a capital increase by capitalization of reserves,
profits or share premium, or (2) 25% of the voting shares in the case of any other extraordinary general meeting. If such quorum required by
French  law  is  not  met,  the  meeting  is  adjourned. There  is  no  quorum  requirement  under  French  law  when  an  ordinary  general  meeting  or  an
extraordinary general meeting is reconvened where shareholders are voting on a capital increase by capitalization of reserves, profits or share
premium, but the reconvened meeting may consider only questions that were on the agenda of the

238

adjourned meeting. When any other extraordinary general meeting is reconvened, the required quorum under French law is 20% of the shares
entitled to vote. The reconvened meeting may consider only questions that were on the agenda of the adjourned meeting. If a quorum is not met
at a reconvened meeting requiring a quorum, then the meeting may be adjourned for a maximum of two months.

Finally,  the  Company  follows  French  law  with  respect  to  shareholder  approval  requirements  in  lieu  of  the  various  shareholder  approval
requirements of Nasdaq Listing Rule 5635, which requires a Nasdaq listed company to obtain shareholder approval prior to certain issuances of
securities, including: (a) issuances in connection with the acquisition of the stock or assets of another company if upon issuance the issued shares
will equal 20% or more of the number of shares or voting power outstanding prior to the issuance, or if certain specified persons have a 5% or
greater interest in the assets or company to be acquired (Nasdaq Listing Rule 5635(a)); (b) issuances or potential issuances that will result in a
change of control of us (Nasdaq Listing Rule 5635(b)); (c) issuances in connection with equity compensation arrangements (Nasdaq Listing Rule
5635(c));  and  (d)  20%  or  greater  issuances  in  transactions  other  than  public  offerings,  as  defined  in  the  Nasdaq  rules  (Nasdaq  Listing  Rule
5635(d)).  Under  French  law,  the  Company’s  shareholders  may  approve  issuances  of  equity,  as  a  general  matter,  through  the  adoption  of
delegation of authority resolutions at the Company’s meeting of shareholders pursuant to which shareholders may delegate their authority to the
Executive  Board  to  increase  the  Company’s  share  capital  within  specified  parameters  set  by  the  shareholders,  which  may  include  a  time
limitation to carry out the share capital increase, the cancellation of their preferential subscription rights to the benefit of named persons or a
category  of  persons,  specified  price  limitations  and/or  specific  or  aggregate  limitations  on  the  size  of  the  share  capital  increase.  Due  to
differences between French law and corporate governance practices and Nasdaq Listing Rule 5635, the Company follows French home country
practice, rather than complying with this Nasdaq Listing Rule.

Item 16H. Mine Safety Disclosure.

Not applicable.

Item 16I. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections

Not applicable.

Item 16J. Insider Trading Policies

Innate has adopted Insider Trading Policies governing the purchase, sale, and other dispositions of securities by directors, senior management,
and employees that is reasonably designed to promote compliance with applicable insider trading laws, rules and regulations, and any applicable
listing standards. A copy of the policy is included as Exhibit 11.1.

Item 16K. Cybersecurity

In  order  to  assess,  identify  and  manage  material  risks  from  cybersecurity  threats,  the  Company  maintains  a  cybersecurity  roadmap,  which
includes processes for information technology, or IT, operations, technologies, business continuity and governance. The cybersecurity roadmap
is based on an assessment performed by a third-party consultant.

To assess and manage material cybersecurity risks, the Company has established a dedicated steering committee, chaired by the Chief Financial
Officer. The steering committee is responsible for:

•

defining the cybersecurity priorities,

239

•

endorsing the cybersecurity roadmap and overseeing its execution,

• monitoring  the  ongoing  implementation  of  our  risk  management  strategy  for  IT  infrastructure,  systems,  vendors,  and  regulatory

compliance,

tracking cybersecurity incidents, and

preparing and overseeing mitigation plans implementation.

•

•

Employees at each level of the organization receive regular training sessions about cybersecurity risks. Moreover, the company relies on external
specialists  and  vendors  for  technical  matters  for  which  the  Company  has  limited  skills  or  infrastructure. All  external  subcontractors  and  IT
systems that manage sensitive processes or data are selected taking into account cybersecurity and data protection considerations, in particular by
checking the certifications held by service providers or suppliers and performing, when appropriate, qualification and follow-up audits.

At Innate Pharma, cybersecurity risks are integrated within our overall risk management framework. Each year, the Vice President, Compliance
&  Operations  gathers  input  from  various  stakeholders  at  the  Company  and  identifies  the  risks  facing  our  business  and  regularly  presents  the
identified material risks, including cybersecurity risks to the Audit Committee. This reporting covers various matters, including the cybersecurity
risks identified and proposed mitigation or preventative measures. Our risk assessment is performed regularly and is subject to change in case of
any significant change or event during the year. In case of a significant cybersecurity incident, the cybersecurity steering committee would assess
the incident severity, propose the appointment of an appropriate crisis unit and submit an action plan for the Executive Board’s endorsement. If
the  incident  is  considered  as  critical  to  the  Company’s  cybersecurity,  the  incident  will  be  escalated  to  the  Audit  Committee  and  to  the
Supervisory Board.

As  of  the  filing  of  this  Form  20-F,  the  Company  is  not  aware  of  any  cyber-attacks  that  have  occurred  since  the  beginning  of  2024  that  have
materially affected, or are reasonably likely to materially affect the Company, including its business strategy, results of operations or financial
condition. Although we have put in place the cybersecurity processes described above, we remain exposed to cybersecurity attacks and incidents
and misuse or manipulation of any of our IT systems, which could have a material adverse effect on our business strategy, results of operations
or financial condition. See “Risk Factors – Risks Related to Innate Pharma's Organization and Operations” in Item 3.D. of this Annual Report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMS

To the shareholders and the Board of Directors of Innate Pharma S.A.

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of Innate Pharma S.A. and its subsidiary (the “Company”) as of
December 31, 2024, the related consolidated statements of income (loss), comprehensive income (loss), change in shareholders’ equity, and cash
flows, for the year ended December 31, 2024, and the related notes (collectively referred to as the “financial statements”). In our opinion, the
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and the results of its
operations and its cash flows for the year then ended, in conformity with IFRS Accounting Standards as issued by the International Accounting
Standards Board (IASB).

We  have  also  audited,  in  accordance  with  the  standards  of  the  Public  Company Accounting  Oversight  Board  (United  States)  (PCAOB),  the
Company’s  internal  control  over  financial  reporting  as  of  December  31,  2024,  based  on  criteria  established  in  Internal  Control  —  Integrated
Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the Treadway  Commission  and  our  report  dated April  30,  2025,
expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s
financial  statements  based  on  our  audit. We  are  public  accounting  firms  registered  with  the  PCAOB  and  are  required  to  be  independent  with
respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and
Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audit included
performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and  performing
procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as
well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

Critical Audit Matters

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current-period  audit  of  the  financial  statements  that  was
communicated  or  required  to  be  communicated  to  the  audit  committee  and  that  (1)  relates  to  accounts  or  disclosures  that  are  material  to  the
financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters
does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter
below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

F-2

Collaboration and licensing agreements with AstraZeneca and Sanofi

Critical Audit Matter Description

As  described  in  the  note  13.1-  Revenue  from  collaboration  and  licensing  agreements,  the  Company  has  recognized  revenue  and  contract
liabilities for the fiscal year 2024 from the following collaboration agreements:

(i)  Co-development  and  commercialization  agreement  with  AstraZeneca  signed  in  2015  for  the  product  Monalizumab  and  a  multi-term
agreement signed in 2018 and subsequent amendment signed in 2020 granting the entirety of the oncology rights to Monalizumab. The execution
of these agreements resulted in:

–

–

recognized revenue of 4,4 million euros for the year ended December 31, 2024, and

collaboration liabilities of 48,6 million euros as of December 31, 2024;

(ii) Collaboration and license agreement with Sanofi signed in 2016 for the development of "NK Cell engagers" in oncology. For the year ended
December 31, 2024, the execution of this contract resulted in recognized revenue of 4 million euros;

(iii) Co-development and license agreement for IPH5201 signed with AstraZeneca in 2018 and subsequent amendment signed in 2022. For the
year ended December 31, 2024, the execution of this contract resulted in recognized revenue of 2,1 million euros;

(iv)  Research  collaboration  and  license  agreement  with  Sanofi  signed  in  2022  for  the ANKET®  program  for  the  development  of  "NK  Cell
engagers first-in-class". The execution of these agreements resulted in:

–

–

recognized revenue of 2,1 million euros for the year ended December 31, 2024, and

deferred revenues of 3,2 million euros as of December 31, 2024;

In assessing the revenue recognition accounting treatment of such complex agreements, Management considers the contractual terms that could
impact  performance  obligations,  transaction  price  allocation,  and  the  timing  of  revenue  recognition.  This  assessment  involves  significant
judgements from Management.

The principal considerations for our determination that performing procedures relating to Research collaboration and license agreements with
AstraZeneca  and  Sanofi  is  a  critical  audit  matter  are  (i)  the  significant  judgment  by  management  in  identifying  the  performance  obligations,
determining  and  allocating  the  transaction  price,  and  assessing  the  timing  of  the  revenue  recognition,  including  significant  judgments  and
assumptions  on  a  contract  by  contract  basis  and  (ii)  a  high  degree  of  auditor  judgment,  subjectivity,  and  effort  in  performing  procedures  and
evaluating audit evidence related to management’s assessment of the revenue recognition accounting treatment.

How the Critical Audit Matter was Addressed in the Audit

Addressing  the  matter  involved  performing  procedures  and  evaluating  audit  evidence  in  connection  with  forming  our  overall  opinion  on  the
consolidated  financial  statements. These  procedures  included  testing  the  effectiveness  of  controls  relating  to  management’s  assessment  of  the
revenue recognition. These procedures also included, among others,

(i) analyzing the accounting position papers prepared by management in accordance with applicable accounting principles,

(ii) reviewing the agreements and amendments signed between Innate Pharma and its partners to assess the potential impacts on performance
obligations, transaction price determination and allocation, and the timing of revenue recognition,

F-3

(iii) confirming with AstraZeneca the repayment costs impacting the collaboration liabilities,

(iv)  obtaining  and  reconciling  the  key  operational  documents  like  related  clinical  projects  budgets  with  the  accounting  memos  provided  by
Management,

(v) verifying that the note to the consolidated financial statements “13.1- Revenue from collaboration and licensing agreements” is appropriate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Innate Pharma S.A.

Opinion on the Financial Statements

We have audited the accompanying statements of financial position of Innate Pharma S.A. and its subsidiary (the “Company”) as of December
31, 2023 and 2022, the related consolidated statements of income (loss), comprehensive income (loss), change in shareholders’ equity, and cash
flows,  for  each  of  the  two  years  in  the  period  ended  December  31,  2023,  and  the  related  notes  (collectively  referred  to  as  the  “financial
statements”).  In  our  opinion,  the  financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  as  of
December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the two years in the period ended December 31,
2023, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s
financial  statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public  Company Accounting  Oversight  Board
(United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws
and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not
required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required
to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the
Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud,
and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and
disclosures  in  the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by
management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for
our opinion.

Note 1: The company

NOTES TO FINANCIAL STATEMENTS

Innate Pharma S.A. is a global, clinical-stage biotechnology company developing immunotherapies for cancer patients. Its innovative approach
aims to harness the innate immune system through three therapeutic approaches: monoclonal antibodies, multispecific NK Cell Engagers via its
ANKET®  (Antibody-based  NK  cell  Engager  Therapeutics)  proprietary  platform  and  Antibody  Drug  Conjugates  (ADC).  Innate’s  portfolio
includes its lead proprietary program lacutamab, developed in advanced form of cutaneous T cell lymphomas and peripheral T cell lymphomas,
monalizumab developed with AstraZeneca in non-small cell lung cancer, several ANKET® drug candidates to address multiple tumor types as
well as IPH4502 a differentiated ADC in development in solid tumors. Innate Pharma is a trusted partner to biopharmaceutical companies such
as Sanofi and AstraZeneca, as well as leading research institutions, to accelerate innovation, research and development for the benefit of patients.

From its inception, the Company has incurred losses due to its research and development (“R&D”) activity. The financial year ended December
31, 2024 generated a €49,471 thousand net loss. As of December 31, 2024, the shareholders’ equity amounted to €8,834 thousand. Subject to
potential new milestone payments related to its collaboration agreements, the Company anticipates incurring additional losses until such time, if
ever, that it can generate significant revenue from its product candidates in development.

The  Company’s  future  operations  are  highly  dependent  on  a  combination  of  factors,  including:  (i)  the  success  of  its  R&D;  (ii)  regulatory
approval and market acceptance of the Company’s future drug candidates; (iii) the timely and successful completion of additional financing; and
(iv) the development of competitive therapies by other biotechnology and pharmaceutical companies. As a result, the Company is and should
continue,  in  the  short  to  mid-term,  to  be  financed  through  partnership  agreements  for  the  development  and  commercialization  of  its  drug
candidates and through the issuance of new equity instruments.

The Company’s activity is not subject to seasonal fluctuations.

As  of  December  31,  2024,  the  Company  had  one  wholly  owned  subsidiary:  Innate  Pharma,  Inc.,  incorporated  under  the  laws  of  Delaware  in
2009.

This subsidiary is fully consolidated.

1.1.

Significant contracts

The following paragraphs describe the key provisions of significant contracts.

a)

Agreements related to monalizumab with Novo Nordisk A/S and with AstraZeneca

2014 Novo Nordisk A/S monalizumab agreement

On  February  5,  2014,  the  Company  acquired  from  Novo  Nordisk A/S  full  development  and  commercialization  rights  to  monalizumab.  Novo
Nordisk A/S received €2.0 million in cash and 600,000 ordinary shares at a price of €8.33 per share (€5.0 million). Novo Nordisk A/S is eligible
to  receive  up  to  €20.0  million  in  potential  regulatory  milestones  and  single-digit  tiered  royalties  on  sales  of  monalizumab  products.  The
agreement  with  Novo  Nordisk  A/S  included  a  right  to  additional  consideration  in  the  event  of  an  out-licensing  agreement.  Consequently,
following  the  agreement  signed  with  AstraZeneca  in  April  2015  (as  described  below),  the  Company  paid  to  Novo  Nordisk  A/S  additional
consideration of €6.5 million (paid in April 2016). Following the exercise of the option by AstraZeneca in October 2018

F-12

(as described below), Novo Nordisk A/S became entitled to a second and final additional payment amounting to $15.0 million (€13.1 million)
which was recognized as a liability as of December 31, 2018 and was paid in February 2019. There are no other potential additional milestones
payments due to Novo Nordisk A/S. These amounts were added to the net book value of the intangible asset and are amortized according to the
same amortization plan as the initial €7.0 million recognized in 2014.

The net book value of the license amounted to €0 as of December 31, 2024.

Refer to Notes 2.h, 2.j and 6 for accounting description.

2015 AstraZeneca monalizumab agreements

Under  co-development  and  option  agreements  signed  with AstraZeneca  in  2015,  the  Company  granted  to AstraZeneca  an  exclusive  license,
subject to certain exclusions, to certain of its patents and know-how to develop, manufacture and commercialize licensed products, including
monalizumab,  in  the  field  of  diagnosis,  prevention  and  treatment  of  oncology  diseases  and  conditions.  The  Company  further  granted  to
AstraZeneca  a  worldwide,  non-exclusive  license  to  certain  of  its  other  patents  to  develop,  manufacture  and  commercialize  licensed  products,
including monalizumab, in the field of diagnosis, prevention and treatment of oncology diseases and conditions.

The Company received an initial payment of $250 million under these agreements in June 2015, of which $100 million was paid to the Company
as an initial payment for the co-development agreement and $150 million was paid to the Company as consideration for the option agreement.
On  October  22,  2018,  AstraZeneca  exercised  this  option  and  the  Company  and  AstraZeneca  entered  into  the  2018  AZ  Option  Agreement,
triggering the payment of $100.0 million, which was received by the Company in January 2019.

Following the option exercise, AstraZeneca became the lead party in developing the licensed products and must use commercially reasonable
efforts to develop, obtain regulatory approval for and commercialize each licensed product in certain major markets.

In July 31, 2019, the Company notified AstraZeneca of its decision to co-fund a future monalizumab Phase 3 clinical development program.

In  September  2020,  the  Company  signed  an  amendment  to  the  collaboration  and  license  agreement  concluded  with  AstraZeneca  in  2015.
Following  the  analysis  of  a  longer  patient  follow-up  as  well  as  the  maturation  of  the  survival  data  of  the  Cohort  2,  and  after  discussion  with
AstraZeneca,  the  Company  agreed  to  amend  the  original  agreement.  This  amendment  changed  the  financial  terms  relating  to  the  milestone
payment expected following the treatment of the first patient with AstraZeneca in the first Phase 3 trial evaluating monalizumab. The original
agreement signed in 2015 provided for a milestone payment of $100 million. Following the inclusion by AstraZeneca of the first patient in the
first Phase 3 trial evaluating monalizumab (INTERLINK-1) in October 2020, and in accordance with the amendment signed in September 2020,
the Company received a payment of $50 million . An additional payment of $50 million was subject to an interim analysis. On August 1, 2022,
the Company announced that the combination of monalizumab and cetuximab did not reach the pre-specified efficacy threshold in the protocol-
planned  interim  futility  analysis  of  the  Phase  3  INTERLINK-1  clinical  study  conducted  by AstraZeneca. AstraZaneca  has  thus  informed  the
Company that the study will be discontinued. Consequently, the Company is not eligible for the additional payment of $50.0 million as provided
for in the amendment signed in September 2020.

F-13

On June 2022, the Company received an additional payment of $50.0 million from AstraZeneca following the inclusion of the first patient in the
second trial evaluating monalizumab, on April 2022 ("PACIFIC-9").

In addition to the initial payment, the option exercise payment and the payment received for the inclusion of the first patient in the first Phase 3
trial,  AstraZeneca  is  obligated  to  pay  the  Company  up  to  $775  million  in  the  aggregate  upon  the  achievement  of  certain  development  and
regulatory  milestones  ($350  million)  and  commercialization  milestones  ($425  million).  The  Company  is  eligible  to  receive  tiered  royalties
ranging  from  a  low  double-digit  to  mid-teen  percentage  on  net  sales  of  licensed  products  outside  of  Europe. The  Company  is  required  for  a
defined period of time to co-fund 30% of the Phase 3 clinical trials of licensed products, subject to an aggregate cap, in order to receive 50% of
the profits in Europe.

Refer to Notes 2.p and 13.a for accounting description.

b)

Agreement related to Lumoxiti with AstraZeneca

In October 2018, the Company obtained an exclusive license from AstraZeneca under certain patents and know-how to develop, manufacture
and  commercialize  Lumoxiti  for  all  uses  in  humans  and  animals  in  the  United  States,  the  European  Union  and  Switzerland.  Under  this
Agreement, AstraZeneca was obligated to provide support for the continued development and commercialization of Lumoxiti in the European
Union and Switzerland prior to regulatory submission and approval as well as support for the continued commercialization of Lumoxiti in the
United  States  for  a  specified  period  running  until  September  30,  2020.  Following  this  transition  period,  the  company  took  charge  of  all
marketing of Lumoxiti in the United States.

Under the agreement signed in 2018, the Company was obligated to pay a $50.0 million initial payment (€43.8 million), which it paid in January
2019, and a $15.0 million regulatory milestone (€13.4 million), which was paid in January 2020. The Company has reimbursed AstraZeneca for
the development, production and commercialization costs it incurs during the transition period, ended in September 30, 2020.

Further  to  the  decision  to  terminate  the  Lumoxiti  Agreement  and  termination  notice  sent  in  December  2020,  a  termination  and  transition
agreement  was  discussed  and  executed,  effective  as  of  June  30,  2021  terminating  the  Lumoxiti  Agreement  as  well  as  Lumoxiti  related
agreements  (including  the  supply  agreement,  the  quality  agreement  and  other  related  agreements)  and  transferring  of  the  U.S.  marketing
authorization and distribution rights of Lumoxiti back to AstraZeneca. The FDA has effectively transferred the BLA to AstraZeneca on February
8, 2022. AstraZeneca has reimbursed Innate Pharma for all Lumoxiti related costs, expenses and benefited net sales. In the year ended December
31, 2020, the Company reported a contingent liability of up to $12.8 million in its consolidated financial statements, which was related to the
splitting  of  certain  manufacturing  costs.  As  part  of  the  termination  and  transition  agreement,  Innate  and  AstraZeneca  agreed  to  split  these
manufacturing costs, and Innate has paid $6.2 million to AstraZeneca (€5.9 million) on April 2022.

Following the termination and transition agreement signed in 2021, Lumoxiti activities are presented as discontinued operations as of December
31, 2021 and 2022, respectively. As of December 31, 2023, the transition of all Lumoxiti rights and the transfer of activities to AstraZeneca has
been fully completed.

Refer to Notes 2.v and 17 for accounting description.

c)

Agreement related to IPH5201 with AstraZeneca

In October 2018, the Company signed a collaboration and option agreement with AstraZeneca for co-development and co-commercialization of
IPH5201. Under the agreement, AstraZeneca paid the

F-14

Company  a  $50.0  million  upfront  payment  ($26.0  million  paid  in  October  2018  and  $24.0  million  paid  in  January  2019),  and  a  milestone
payment of $5.0 million paid in June 2020 following the assay of the first patient in the first Phase 1 trial evaluating IPH5201, in March 2020.
AstraZeneca is obligated to pay the Company up to an aggregate of $5.0 million upon the achievement of certain development milestones.

On June 1, 2022, the Company signed an amendment to the collaboration and license option agreement IPH5201 concluded with AstraZeneca in
October 2018. Subsequently, the Company announced on June 3, 2022 the progress of IPH5201 towards a study of Phase 2 in lung cancers for
which the Company will be the sponsor. In accordance with the amendment signed on June 1, 2022, the Company is eligible for a milestone
payment of $5.0 million by AstraZeneca. This milestone payment was received on August 2, 2022 by the Company.

Upon  exercise  of  its  option  under  the  agreement,  AstraZeneca  is  committed  to  pay  an  option  exercise  fee  of  $25.0  million  and  up  to
$800.0 million in the aggregate upon the achievement of certain development and regulatory milestones ($300 million) and commercialization
milestones ($500 million). The arrangement also provides for a 50% profit share in Europe if the Company opts into certain co-promoting and
late stage co-funding obligations. In addition, the Company would be eligible to receive tiered royalties ranging from a high-single digit to mid-
teen  percentage  on  net  sales  of  IPH5201,  or  from  a  mid-single  digit  to  low-double  digit  percentage  on  net  sales  of  other  types  of  licensed
products, outside of Europe. The royalties payable to the Company under the agreement may be reduced under certain circumstances, including
loss of exclusivity or lack of patent protection. As of December 31, 2020, since the Company had fulfilled all of its commitments on preclinical
work related to the start of Phase 1 of the IPH5201 program, the initial payment of $50.0 million and the milestone payment of $5.0 million were
fully recognized in revenue. The Company was reimbursed by AstraZeneca for certain research and development expenses related to IPH5201
for the year ended December 31, 2024. The Company has the option to co-fund 30% of the shared development expenses related to the Phase 3
clinical  trials  in  order  to  acquire  co-promotion  rights  and  to  share  in  50%  of  the  profits  and  losses  of  licensed  products  in  Europe.  If  the
Company does not opt into the co-funding obligations, among other things, its right to share in 50% of the profits and losses in Europe and right
to co-promote in certain European countries will terminate and will be replaced by rights to receive royalties on net sales at the rates applicable
to outside of Europe. Additionally, certain milestone payments that may be payable to the Company would be materially reduced.

Agreement related to additional preclinical molecules with AstraZeneca

In  October  2018,  the  Company  granted  to AstraZeneca  four  exclusive  options  that  are  exercisable  until  IND  approval  to  obtain  a  worldwide,
royalty-bearing, exclusive license to certain of the Company’s patents and know-how relating to certain specified pipeline candidates to develop
and  commercialize  optioned  products  in  all  fields  of  use.  Pursuant  to  the  agreement, AstraZeneca  paid  the  Company  a  $20.0  million  upfront
payment (€17.4 million) in October 2018. The Company recognized this upfront payment in the consolidated statement of financial position as
deferred revenue as of December 31, 2018, until the exercise or the termination of each option at the earliest.

During 2022 first semester, the Company received from AstraZeneca a notice that it will not exercise its option to license the four preclinical
programs  covered  in  the  "Future  Programs  Option  Agreement".  Innate  has  now  regained  full  rights  to  further  develop  the  four  preclinical
molecules. Consequently, the entire initial payment of $20.0 million, or €17.4 million was recognized as revenue as of June 30, 2022

acute lymphoblastic leukemia (B-ALL) or high risk-myelodysplastic syndrome (HR-MDS). Following the initiation of the trial, the Company
received a €3.0m milestone from Sanofi during 2021.

On April 15, 2024, the Company announced the treatment of the first patient in the phase 2 dose extension of the Sanofi-led study evaluating the
NK  Cell  Engager  SAR443579/IPH6101  in  various  blood  cancers.  Under  the  terms  of  the  2016  agreement,  this  trial  progress  triggered  a
milestone payment of 4.0 million euros, fully recognized in revenue during the first quarter of 2024 and collected by the Company on May 17,
2024.

On April  23,  2025,  the  Company  announced  that,  in  alignment  with  both  company's  current  strategic  priorities,  Sanofi  and  Innate  agreed  to
terminate the 2016 Agreement as it relates to SAR’579/IPH6101 (CD123 ANKET), effective as of June 30, 2025. Innate will regain the rights on
July 1, 2025. Sanofi and Innate will discuss a transition plan with regard to ongoing studies.

IPH6401/SAR’514

During 2022 first semester, the Company was informed of Sanofi's decision to advance IPH6401/SAR’514 towards regulatory preclinical studies
aimed at studying an investigational new drug. As such, Sanofi has selected a second multi-specific antibody that engages NK cells as a drug
candidate. This selection triggered a €3.0 million milestone payment from Sanofi to the Company. On July 11, 2023, the company announced the
dosing as of June 7, 2023, of the first in a Sanofi-sponsored Phase 1/2 clinical trial, evaluating IPH6401/SAR’514 in relapsed/refractory Multiple
Myeloma. As a consequence, Sanofi made a milestone payment of €2.0 million to the Company. On March 27, 2025, the Company announced
that the clinical study will be terminated early as Sanofi will now pursue development of IPH6401/SAR’514 in autoimmune indications.

Consolidation method

The Group applies IFRS 10 Consolidated financial statements. IFRS 10 presents a single consolidation model identifying control as the criteria
for consolidating an entity. An investor controls an investee if it has the power over the entity, is exposed or has rights to variable returns from its
involvement with the entity and has the ability to use its power over the entity to affect the amount of the investor’s returns. Subsidiaries are
entities over which the Company exercises control. They are fully consolidated from the date the Group obtains control and are deconsolidated
from the date the Group ceases to exercise control. Intercompany balances and transactions are eliminated.

g)

Financial instruments

Financial assets

Financial  assets  are  initially  measured  at  fair  value  plus  directly  attributable  transaction  costs  in  the  case  of  instruments  not  measured  at  fair
value through profit or loss. Directly attributable transaction costs of financial assets measured at fair value through profit or loss are recorded in
the consolidated statement of income (loss).

Under IFRS 9, financial assets are classified in the following three categories:

•

•

•

Financial assets at amortized cost;

Financial assets at fair value through other comprehensive income (“FVOCI”); and

Financial assets at fair value through profit or loss.

The classification of financial assets depends on:

•

•

The characteristics of the contractual cash flows of the financial assets; and

The business model that the entity follows for the management of the financial asset.

Financial assets at amortized cost

Financial assets are measured at amortized cost when (i) they are not designated as financial assets at fair value through profit or loss, (ii) they
are held within a business model whose objective is to hold assets in order to collect contractual cash flows and (iii) they give rise to cash flows
that  are  solely  payments  of  principal  and  interest  on  the  principal  amount  outstanding  (“SPPI”  criterion). They  are  subsequently  measured  at
amortized cost, determined using the effective interest method (“EIR”), less any expected impairment losses in relation to the credit risk. Interest
income,  exchange  gains  and  losses,  impairment  losses  and  gains  and  losses  arising  on  derecognition  are  all  recorded  in  the  consolidated
statement of income (loss).

This category primarily includes trade receivables, as well as other loans and receivables. Long-term loans and receivables that are not interest-
bearing or that bear interest at a below-market rate are discounted when the amounts involved are material.

Financial assets at fair value through other comprehensive income

Financial assets at fair value through other comprehensive income is mainly comprised is composed of debt instruments whose contractual cash
flows represent payments of interest or repayments of principal, and which are managed with a view to collecting cash flows and selling the
asset. Gains and losses arising from changes in fair value are recognized in equity within the statement of comprehensive income in the period in
which they occur. When such assets are derecognized, the cumulative gains and losses previously recognized in equity are reclassified to profit
or  loss  for  the  period  within  the  line  items  Financial  income  or  Financial  expenses. The  Company  did  not  hold  this  type  of  instrument  as  of
January 1, 2024 or as of December 31, 2024.

F-22

Financial assets at fair value through profit or loss

Financial assets at fair value through profit or loss is comprised of:

•

•

financial assets that are not part of the above categories; and

instruments that management has designated as “fair value through profit or loss” on initial recognition.

Gains and losses arising from changes in fair value are recognized in profit or loss within the line items financial income or financial expenses.

Impairment of financial assets measured at amortized cost

The main assets involved are trade receivables and others. Trade receivables are recognized when the Company has an unconditional right to
payment  by  the  customer.  Impairment  losses  on  trade  receivables  and  others  are  estimated  using  the  expected  loss  method,  in  order  to  take
account  of  the  risk  of  payment  default  throughout  the  lifetime  of  the  receivables.  The  expected  credit  loss  is  estimated  collectively  for  all
accounts receivable at each reporting date using an average expected loss rate, determined primarily on the basis of historical credit loss rates.
However, that average expected loss rate may be adjusted if there are indications of a likely significant increase in credit risk. If a receivable is
subject to a known credit risk, a specific impairment loss is recognized for that receivable. The amount of expected losses is recognized in the
balance  sheet  as  a  reduction  in  the  gross  amount  of  accounts  receivable.  Impairment  losses  on  accounts  receivable  are  recognized  within
Operating expenses in the consolidated statement of income (loss).

Financial liabilities

Financial liabilities comprise deferred revenue, collaboration liabilities, loans and trade and other payables.

Financial  liabilities  are  initially  recognized  on  the  transaction  date,  which  is  the  date  that  the  Company  becomes  a  party  to  the  contractual
provisions of the instrument. They are derecognized when the Company’s contractual obligations are discharged, cancelled or expire.

Loans  are  initially  measured  at  fair  value  of  the  consideration  received,  net  of  directly  attributable  transaction  costs.  Subsequently,  they  are
measured at amortized cost using the EIR method. All costs related to the issuance of loans, and all differences between the issuance proceeds
net of transaction costs and the value on redemption, are recognized within financial expenses in the consolidated statement of income (loss)
over the term of the debt using the EIR method.

Other financial liabilities include trade accounts payable, which are measured at fair value (which in most cases equates to face value) on initial
recognition, and subsequently at amortized cost.

Cash and cash equivalents

Cash equivalents are short-term, highly liquid investments, that are readily convertible to known amounts of cash and which are subject to an
insignificant risk of changes in value. Cash and cash equivalents comprise the cash that is held at the bank and petty cash as well as the short-
term fixed deposits for which the maturity is less than three months.

For the purpose of establishing the statement of cash flows, cash and cash equivalents include cash in hand, demand deposits and short fixed-
term deposits with banks and short-term highly liquid investments with original maturities of three months or less, net of bank overdrafts.

Cash and cash equivalents are initially recognized at their purchase costs on the transaction date, and are subsequently measured at fair value.
Changes in fair value are recognized in profit or loss.

F-23

Fair value of financial instruments

Under IFRS 13 Fair value measurement and IFRS 7 Financial instruments: disclosures, or IFRS 7, fair value measurements must be classified
using a hierarchy based on the inputs used to measure the fair value of the instrument. This hierarchy has three levels:

•

•

•

level 1: fair value calculated using quoted prices in an active market for identical assets and liabilities;

level 2: fair value calculated using valuation techniques based on observable market data such as prices of similar assets and liabilities
or parameters quoted in an active market; and

level 3: fair value calculated using valuation techniques based wholly or partly on unobservable inputs such as prices in an inactive
market or a valuation based on multiples for unlisted securities.

h)

Intangible assets

Research and development (R&D) expenses

In accordance with IAS 38 Intangible assets, or IAS 38, expenses on research activities are recognized as an expense in the period in which it is
incurred.

An internally generated intangible asset arising from the Company’s development activities is recognized only if all of the following conditions
are met:

•

•

•

•

Technically feasible to complete the intangible asset so that it will be available for use or sale;

The Company has the intention to complete the intangible assets and use or sell it;

The Company has the ability to use or sell the intangible assets;

The intangible asset will generate probable future economic benefits, or indicate the existence of a market;

• Adequate technical, financial and other resources to complete the development are available; and

•

The Company is able to measure reliably the expenditure attributable to the intangible asset during its development.

Because  of  the  risks  and  uncertainties  related  to  regulatory  approval,  the  R&D  process  and  the  availability  of  technical,  financial  and  human
resources necessary to complete the development Phases of the product candidates, the six criteria for capitalization are usually considered not to
have been met until the product candidate has obtained marketing approval from the regulatory authorities. Consequently, internally generated
development expenses arising before marketing approval has been obtained, mainly the cost of clinical trials, are generally expensed as incurred
within Research and development expenses.

However,  some  clinical  trials,  for  example  those  undertaken  to  obtain  a  geographical  extension  for  a  molecule  that  has  already  obtained
marketing approval in a major market, may in certain circumstances meet the six capitalization criteria under IAS 38, in which case the related
expenses are recognized as an intangible asset. These related costs are capitalized when they are incurred and amortized on a straight line basis
over their useful lives beginning when marketing approval is obtained.

Licenses

Payments  for  separately  acquired  research  and  development  are  capitalized  within  “Other  intangible  assets”  provided  that  they  meet  the
definition of an intangible asset: a resource that is (i) controlled by the

F-24

Group, (ii) expected to provide future economic benefits for the Group and (iii) identifiable (i.e. it is either separable or arises from contractual
or legal rights).

In  accordance  with  paragraph  25  of  IAS  38  standard,  the  first  recognition  criterion,  relating  to  the  likelihood  of  future  economic  benefits
generated by the intangible asset, is presumed to be achieved for research and development activities when they are acquired separately.

In this context, amounts paid to third parties in the form of initial payments or milestone payments relating to product candidates that have not
yet obtained a regulatory approval are recognized as intangible assets. These rights are amortized on a straight-line basis:

(i) after obtaining the regulatory approval, over their useful life; or

(ii) after  entering  in  an  out-license  collaboration  agreement  with  a  third-party  partner,  over  their  estimated  useful  life.  This  estimated
useful life takes into consideration the period of protection of the out-licensed exclusivity rights and the anticipated period over which
the Company will receive the economic benefits of the asset.

Unamortized rights (before marketing authorization) are subject to impairment tests in accordance with the method defined in Note 6.

When intangible assets acquired separately are acquired through variable or conditional payments, these payments are recognized as an increase
of the carrying amount of the intangible asset when they become due. Royalties due by the Company related to acquired licenses are recognized
as operating expenses when the Company recognizes sales subject to royalties.

Estimate of the useful life of the acquired licenses: intangible assets are amortized on a straight line basis over their anticipated useful life. The
estimated useful life is the period over which the asset provides future economic benefits. It is estimated by management and is regularly revised
by  taking  into  consideration  the  period  of  development  over  which  it  expects  to  receive  economic  benefits  such  as  collaboration  revenues,
royalties, product of sales, etc. However, given the uncertainty surrounding the duration of the R&D activities for the programs in development
and  their  likelihood  to  generate  future  economic  benefits  to  the  Company,  the  estimated  useful  life  of  the  rights  related  to  these  programs  is
rarely longer than the actual development Phase of the product candidate. When a program is in commercialization Phases, the useful life takes
into account the protection of the exclusivity rights and the anticipated period of commercialization without taking into account any extension or
additional patents. The prospective amendment of the amortization plan of the monalizumab intangible asset, which is modified according to the
estimate ending date of the Phase 2 clinical trial is described in Note 6.

Other intangible assets

Other intangible assets consist of acquired software. Costs related to the acquisition of software licenses are recognized as assets based on the
costs incurred to acquire and set up the related software. Software is amortized using the straight-line method over a period of one to three years
depending on the anticipated period of use.

i)

Property and equipment

Property  and  equipment  are  carried  at  acquisition  cost.  Major  renewals  and  improvements  are  capitalized  while  repairs  and  maintenance  are
expensed as incurred.

Property and equipment are depreciated over their estimated useful lives using the straight-line depreciation method. Leasehold improvements
are depreciated over the life of the improvement or the remaining lease term, whichever is shorter.

F-25

The  headquarters  of  the  Company  was  split  into  several  components  (e.g.,  foundations,  structure,  electricity,  heating  and  ventilation  systems)
which are depreciated over different useful lives according to the anticipated useful life of these elements.

Depreciation periods are as follows:

Buildings and improvements on buildings

Installations
Technical installations and equipment

Equipment and office furniture
Computers and IT equipment

j)

Impairment of intangible assets, property, and equipment

The  Group  assesses  at  the  end  of  each  reporting  period  whether  there  is  an  indication  that  intangible  assets,  property  and  equipment  may  be
impaired. If any indication exists, the Group estimates the recoverable amount of the related asset.

Whether or not there is any indication of impairment, intangible assets not yet available for use are tested for impairment annually by comparing
their carrying amount with their recoverable amount.

Pursuant to IAS 36—Impairment of Assets, criteria for assessing indication of loss in value may notably include performance levels lower than
forecast,  a  significant  change  in  market  data  and/or  the  regulatory  environment,  the  asset  development  strategy  approved  by  management,  or
obsolescence  or  physical  damage  of  the  asset  not  included  in  the  amortization/depreciation  schedule.  The  recognition  of  an  impairment  loss
alters the amortizable/depreciable amount and potentially, the amortization/depreciation schedule of the relevant asset.

Impairment  losses  on  intangible  assets,  property  and  equipment  shall  be  reversed  subsequently  if  the  impairment  loss  no  longer  exists  or  has
decreased. In such case, the recoverable amount of the asset is to be determined again so that the reversal can be quantified. The asset value after
reversal  of  the  impairment  loss  may  not  exceed  the  carrying  amount  net  of  depreciation/amortization  that  would  have  been  recognized  if  no
impairment loss had been recognized in prior periods.

The Group does not have any intangible assets with an indefinite useful life. However, as explained in Note 2.h, the Group recognized intangible
assets in progress, which will be amortized once marketing authorization is received or when out licensing has been agreed.

k)

Employee benefits

Long-term pension benefits

Company employees are entitled to pension benefits required by French law:

•

•

Pension benefit, paid by the Company upon retirement (i.e. defined benefit plan); and

Pension payments from social security entities, financed by contributions from businesses and employees (i.e. defined contribution
plan”).

In addition, the Company has implemented an additional, non-mandatory, pension plan (“Article 83”), initially for the benefit of executives only.
This plan was extended to the non-executive employees starting on January 1, 2014. This plan meets the definition of defined contribution plan
and is financed

F-26

through a contribution that corresponds to 2.2% of the employee’s annual wage, with the Company paying 1.4% and the employee paying 0.8%.

For the defined benefit plan, the costs of the pension benefit are estimated using the “projected unit credit” method. According to this method,
the pension cost is accounted for in the consolidated statement of income (loss), so that it is distributed uniformly over the term of the services of
the employees. The pension benefit commitments are valued using the actual present value of estimated future payments, adopting the rate of
interest  of  long-term  bonds  in  the  private  sector  (i.e.  Euro  zone AA  or  higher  rated  corporate  bonds  +  10  years). The  difference  between  the
amount of the provision at the beginning of a period and at the close of that period is recognized in the consolidated statement of income (loss)
for the portion representing the costs of services rendered and the net interest costs, and through other comprehensive income for the portion
representing the actuarial gains and losses. The Company’s commitments under the defined benefit plan are not covered by any plan assets.

Payments made by the Company for defined contribution plans are accounted for as expenses in the consolidated statement of income (loss) in
the period in which they are incurred.

Other long-term benefits

The  Company  pays  seniority  bonuses  to  employees  reaching  10,  15  and  20  years  of  seniority.  These  bonuses  represent  long-term  employee
benefits.  Under  IAS  19R  “Employee  benefits”,  they  are  recording  as  a  defined  benefit  obligation  in  the  consolidated  statement  of  financial
position, but their remeasurements is not recognized in the consolidated statement of other comprehensive income (loss).

Other short-term benefits

An accrued expense is recorded for the amount the Company expects to pay its eligible employees in relation to services rendered during the
reporting period (actual legal or implicit obligation to make to these payments on a short-term basis).

l)

Leases

The Company assesses whether a contract is or contains a lease, at inception of the contract. The Company recognizes a right-of-use asset and a
corresponding lease liability with respect to all lease arrangements in which it is the lessee, except for short-term leases (defined as leases with a
lease  term  of  12  months  or  less)  and  leases  of  low  value  assets  (such  as  tablets  and  personal  computers,  small  items  of  office  furniture  and
telephones). For these leases, the Company recognizes the lease payments as an operating expense on a straight-line basis over the term of the
lease unless another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by
using the rate implicit in the lease. If this rate cannot be readily determined, the Company uses its incremental borrowing rate. Lease payments
included in the measurement of the lease liability comprise:

•

•

•

•

fixed lease payments (including in-substance fixed payments), less any lease incentives receivable;

variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date;

the amount expected to be payable by the lessee under residual value guarantees;

the exercise price of purchase options, if the lessee is reasonably certain to exercise the options; and

F-27

•

payment of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease.

The  lease  liability  is  included  in  the  financial  liabilities  in  the  consolidated  statement  of  financial  position  and  is  subsequently  measured  by
increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount
to reflect the lease payments made.

The  right-of-use  assets  comprise  the  initial  measurement  of  the  corresponding  lease  liability,  lease  payments  made  at  or  before  the
commencement  day,  less  any  lease  incentives  received  and  any  initial  direct  costs. They  are  subsequently  measured  at  cost  less  accumulated
depreciation and impairment losses.

Whenever the Company incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the
underlying asset to the condition required by the terms and conditions of the lease, a provision is recognized and measured under IAS 37. To the
extent  that  the  costs  relate  to  a  right-of-use  asset,  the  costs  are  included  in  the  related  right-of-use  asset,  unless  those  costs  are  incurred  to
produce inventories.

Right-of-use assets are depreciated over the shorter period of lease term and useful life of the underlying asset. If a lease transfers ownership of
the underlying asset or the cost of the right-of-use asset reflects that the Company expects to exercise a purchase option, the related right-of-use
asset is depreciated over the useful life of the underlying asset. The depreciation starts at the commencement date of the lease.

The right-of-use assets are included in the property and equipment line item in the consolidated statement of financial position.

The Company applies IAS 36 to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss.

m)

Provisions and contingent liabilities

In  the  course  of  its  business,  the  Company  could  be  exposed  to  certain  risks  and  litigations,  notably  in  relation  to  contractual  arrangements.
Provisions  are  recognized  when  the  Company  has  a  present  legal  or  constructive  obligation  as  a  result  of  past  events,  it  is  probable  that  the
Company is subject to a release of outflow representatives of economic benefits to settle the obligation and a reliable estimate of the amount of
the obligation can be made. Management of the Company estimates the probability and the expected amount of a cash outflow associated with
risks, together with the other information to be provided on possible liabilities. Where the Company expects a provision to be reimbursed, for
example under an insurance contract, the reimbursement is recognized as a separate asset but only when the reimbursement is certain.

In  addition,  the  Company  may  assess  a  potential  obligation  towards  a  third  party  resulting  from  events  the  existence  of  which  will  only  be
confirmed  by  the  occurrence,  or  not,  of  one  or  more  events.  uncertain  futures  which  are  not  totally  under  the  control  of  the  Company;  or  an
obligation  to  a  third  party  for  which  it  is  not  probable  or  certain  that  it  will  result  in  an  outflow  of  resources  without  at  least  equivalent
consideration expected from the latter. These elements are mentioned in note 18 of the group's consolidated financial statements as contingent
liabilities.

n)

Capital

Ordinary  shares  are  classified  in  shareholders’  equity.  Costs  associated  with  the  issuance  of  new  shares  are  directly  accounted  for  in
shareholders’ equity in diminution of issuance premium.

F-28

The Company’s own shares bought in the context of a brokering/liquidity agreement are presented as a reduction in shareholders’ equity until
their cancellation, their reissuance or their disposal.

o)

Share-based compensation

Since  its  inception,  the  Company  has  established  several  plans  for  compensation  paid  in  equity  instruments  in  the  form  of  free  shares
(“Attributions  gratuites  d’actions,”  or  “AGA”),  free  preferred  shares  convertible  into  ordinary  shares  (“Attributions  gratuites  d’actions  de
préférence  convertibles  en  actions  ordinaires,”  or  “AGAP”),  free  performance  shares  (“Attributions  gratuites  d’actions  de  performance,”  or
“AGA  Perf”),  share  subscription  warrants  (“Bons  de  souscription  d’actions,”  or  “BSA”),  redeemable  share  subscription  warrants  (“Bons  de
Souscription  et/ou  d’Acquisition  d’Actions  Remboursables,”  or  “BSAAR”),  granted  to  its  employees,  executives,  members  of  the  Executive
Board and scientific consultants.

Pursuant to IFRS 2—Share-based Payment, these awards are measured at their fair value on the date of grant. The fair value is calculated with
the most relevant formula regarding the conditions and the settlement of each plan.

For share-based compensation granted to employees, executives, members of the Executive Board and scientific consultants, the Company uses
the  Black-Scholes  and  Monte  Carlo  approach  pricing  models  to  determine  the  fair  value  of  the  share-based  compensation.  For  scientific
consultants providing similar services, as the Company cannot estimate reliably the fair value of the goods or services received, it measures the
value of share-based compensation and the corresponding increase in equity, indirectly, by reference to the fair value of the equity instruments
granted also using the Black-Scholes option pricing model. The fair value of free shares included in the model is determined using the value of
the shares at the time of their distribution.

In calculating the fair value of share-based compensation, the Company also considers the vesting period and the employee turnover weighted
average probability as described in Note 11. Other assumptions used are also detailed in Note 11.

The Company recognizes the fair value of these awards as a share-based compensation expense over the period in which the related services are
received  with  a  corresponding  increase  in  shareholders’  equity.  Share-based  compensation  is  recognized  using  the  straight-line  method.  The
share compensation expense is based on awards ultimately expected to vest and is reduced by expected forfeitures.

p)

Revenue

Revenue from collaboration and license agreements

To date, the Company’s revenue results primarily from payments received in relation to research, collaboration and licensing agreements signed
with pharmaceutical companies. These contracts generally provide for components such as:

•

•

non-refundable upfront payments upon signature;

payments for the exercise of the option to acquire licenses of drug candidates;

• milestones  payments  triggered  following  stages  of  development  (scientific  results  obtained  by  the  Company  or  by  the  partner,

obtaining regulatory marketing approvals);

payments related to the Company’s R&D activities;

payments  triggered  by  the  start  of  the  commercialization  of  products  resulting  from  development  work  or  by  crossing  cumulative
thresholds of product sales, as well as the allocation of royalties on future sales of products or a sharing of profits on sales.

•

•

F-29

Under  collaboration  and  license  agreements,  the  Company  may  promise  its  partners  licenses  on  intellectual  property,  as  well  as  research  and
development  services. According  to  IFRS  15,  the  Company  has  to  determine  if  the  promises  included  in  the  contract  are  distinct  (therefore
recognized separately as revenue) or if they have to be combined as a single performance obligation.We conclude that the license is not distinct
from  the  research  and  development  services  when  the  research  and  development  services  involve  the  Company's  own  expertise,  so  that  the
customer cannot benefit from the license alone or in combination with services provided by third parties, or when the intellectual property is at
such a stage of development that the research and development work significantly modifies the initial purpose of the license.

When promises in a collaboration and license agreement are considered as a single performance obligation, the Company has to determine if the
combined performance obligation is satisfied over time or at point in time. If the combined performance obligation is satisfied over time, revenue
recognition is based on the percentage of completion of the costs to be incurred. Non-refundable initial payments are deferred and recognized as
revenue during the period the Company is engaged to deliver services to the customer on the basis of the corresponding costs.

When  promises  in  a  collaboration  and  license  agreement  are  considered  as  separate  performance  obligations,  revenue  is  allocated  to  each
obligation proportionally to its transaction price, which corresponds to a price each performance obligation would have been sold in the context
of a separate transaction.

In accordance with IFRS 15, variable considerations cannot be included in the estimated transaction price as long as it not highly probable that
the related revenue will not reversed in the future. According to the level of uncertainty relating to the results of preclinical and clinical trials and
the decisions relating to the regulatory approvals, variable considerations depending on these events are excluded from the transaction price as
long as the trigger event is not highly probable. When the trigger event occurs, the corresponding milestone is added to the transaction price.
Such adjustments are recorded on a cumulative catch-up basis, which would affect revenues and net income (loss) in the period of adjustment.

Revenues based on royalties, completion of commercialization steps or co-sharing profit from sales are recognized when the corresponding sales
of products are carried out by the partner.

When a collaboration contract grants a partner an option to acquire a licensed intellectual property (“IP”), the Company determines the date of
the transfer of control over the licensed IP. Depending on the Company analysis, revenue related to the option fee will be recognized (i) when
control over the licensed IP transfers (payment related to the exercise of the option being therefore considered as a variable consideration), or,
(ii) deferred until the exercise of the option or its expiration period.

When an agreement only promises development services, the Company will recognize the related revenue when the costs are incurred.

Up-front  and  milestones  payments  and  fees  are  recorded  as  deferred  revenue  upon  receipt  or  when  due,  and  may  require  deferral  of  revenue
recognition to a future period until the Company performs its obligations under these arrangements. Amounts due by the Company in relation to
cost-sharing are recorded as collaboration liability. Amounts payable to the Company are recorded as accounts receivable when the Company’s
right to consideration is unconditional.

See Note 13 for accounting description of significant agreements.

q)

Government financing for research expenditures

Research tax credit

The research tax credit (Crédit d’Impôt Recherche) (the “Research Tax Credit” or “CIR”) is granted by the French tax authorities in order to
encourage  Companies  to  conduct  technical  and  scientific  research.  Companies  that  can  justify  that  these  expenses  meet  the  required  criteria
receive a tax credit that can be used to offset with the income tax due for the same fiscal year. Any excess is a receivable to the French state,
which can be used to pay the income tax that would be due for the 3 following fiscal years. At the end of this period, the receivable is refundable
by the French State. Companies that meet the definition of SME according to European Union criteria are eligible for early reimbursement of
their  CIR.  The  reimbursements  are  made  under  the  European  Community  tax  rules  for  small  and  medium  sized  enterprises  (“SME”)  in
compliance with the applicable regulations in effect.

With the Company no longer qualifying as a SME, the Company decided to sell the receivable relating to the 2023 CIR to a bank. As there is no
specific  guidance  under  IFRS  for  the  transfer  of  this  type  of  assets,  an  analysis  under  IFRS  9  was  made  by  analogy.  Because  the  company
transferred to the bank its contractual right to receive the cash flows from the asset as well as substantially all the risks and rewards of ownership
of that asset, the asset - the 2023 tax credit receivable - was derecognized.

The Research Tax Credit receivable has been historically considered as part of the working capital. Consequently, the cash flows received from
the  tax  authorities  in  2023  (€13  million),  as  well  as  the  cash  flow  received  from  the  bank  in  2024  (€8.6  million),  are  classified  as  Net  cash
generated from / (used in) operating activities.

The  CIR  is  presented  under  other  income,  in  “government  financing  for  research  expenditures”  line  item  in  the  consolidated  statements  of
income  (loss)  as  it  meets  the  definition  of  government  grant  as  defined  in  IAS  20  Accounting  for  government  grants  and  disclosure  of
government assistance.

Subsidies

Government grants are recognized when there is a reasonable assurance that:

•

•

The Company will comply with the conditions attached to the grants; and that

The grants will be received.

A government grant that becomes receivable as compensation for expenses or losses already incurred, or for the purpose of providing immediate
financial support to the Company with no future related costs, is recognized as other income of the period in which it becomes receivable.

Government grants to subsidize capital expenditures are presented in the statement of financial position as deferred income and are recognized as
income on a straight line basis over the useful life of those assets that have been financed through the grants.

A non-repayable loan from the government is treated as a government grant when there is a reasonable assurance that the Company will meet the
terms for non-repayment of the loan. When there is no such assurance, the loan is recorded as a liability under borrowings.

r)

Income tax

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities
and their carrying amounts in the financial statements. Main temporary differences are generally associated with the depreciation of property and
equipment, provisions for pension benefits and tax losses carried forward and also with the deferred tax liabilities /

F-31

assets generated by the application of IFRS 15. Currently enacted tax rates are used in the determination of deferred income tax.

Deferred  tax  assets  are  recognized  to  the  extent  that  it  is  probable  that  future  taxable  profit  will  be  available  against  which  the  temporary
differences can be utilized. Due to Company’s early stage of development, it is not probable that future taxable profit will be available against
which the unused tax losses can be utilized. As Innate Pharma's deferred tax assets and liabilities relate to the same tax authority (France), the
same  taxable  entity,  and  the  same  fiscal  recovery  period,  in  the  application  of  IAS12,  the  entity  offset  deferred  taxes  assets  and  deferred  tax
liabilities in the statement of financial position.

s)

Earnings (loss) per share

In accordance with IAS 33 Earnings per share, basic income (loss) per share is calculated by dividing the income (loss) attributable to equity
holders of the Group by the weighted average number of outstanding shares for the period.

Diluted  income  (loss)  per  share  is  measured  by  dividing  the  income  (loss)  attributable  to  holders  of  equity  and  dilutive  instruments  by  the
weighted average number of outstanding shares and dilutive instruments for the period.

If in the calculation of diluted income (loss) per share, instruments giving deferred rights to capital such as warrants generates an antidilutive
effect, then these instruments are not taken into account.

t)

Other comprehensive income

Items of income and expenses for the period that are recognized directly in equity are presented under “other comprehensive income.” The items
mainly include :

•

Foreign currency translation gain (loss); and

• Actuarial gains and (losses) related to defined benefit obligations.

u)

Segment information

For  internal  reporting  purposes,  and  in  order  to  comply  with  IFRS  8  Operating  segments,  the  Company  performed  an  analysis  of  operating
segments. Following this analysis, the Company considers that it operates within a single operating segment being the R&D of pharmaceutical
products in order to market them in the future. All R&D activities of the Company are located in France. Key decision makers (the Leadership
Team of the Company) monitor the Company’s performance based on the cash consumption of its activities. For these reasons, the Management
of the Group considers it not appropriate to set up separate business segments in its internal reporting.

In addition, Lumoxiti sales were historically considered insignificant in relation to the consolidated financial statements taken as a whole and are
now included in the income statement under "net income from discontinued operations" following the signature of the termination and transition
contract with AstraZeneca in 2021 (see Notes 1.a, 2.v and 17).

v)

Non-current assets held for sale and discontinued operations

A  discontinued  operation  is  a  component  of  an  entity  that  either  has  been  disposed  of,  or  that  is  classified  as  held  for  sale.  It  must  either:
represent a major separate line of business or geographical area of operations; be part of a single coordinated disposal plan; or be a subsidiary
acquired  exclusively  with  a  view  to  resale.  Intercompany  transactions  between  continuing  and  discontinued  operations  are  eliminated  against
discontinuing operations. Non-current assets and disposal groups are classified as assets held for sale if their carrying amount is to be recovered
principally through a sale transaction rather than through

F-32

continuing  use.  This  condition  is  regarded  as  met  only  when  the  sale  is  highly  probable  and  the  asset  (or  disposal  group)  is  available  for
immediate  sale  in  its  present  condition.  They  are  stated  at  the  lower  of  carrying  amount  and  fair  value  less  costs  to  sell  with  any  resulting
impairment recognized. Assets related to discontinued operations and assets of disposal group held for sale are not depreciated. The prior-year
consolidated balance sheet is not restated.

Further  to  the  decision  to  terminate  the  Lumoxiti  Agreement  and  termination  notice  sent  in  December  2020,  a  termination  and  transition
agreement  was  discussed  and  executed,  effective  as  of  June  30,  2021  terminating  the  Lumoxiti  Agreement  as  well  as  Lumoxiti  related
agreements  (including  the  supply  agreement,  the  quality  agreement  and  other  related  agreements)  and  transferring  of  the  U.S.  marketing
authorization  and  distribution  rights  of  Lumoxiti  back  to  AstraZeneca.  Consecutively,  the  activities  related  to  Lumoxiti  are  presented  as  a
discontinued operation for all period presented.

Consequently, in accordance with IFRS5 "non-current assets held for sale and discontinued operations", the Lumoxiti operations are presented in
the  consolidated  statement  of  income  (loss)  and  the  notes  to  the  consolidated  financial  statements  as  a  discontinued  operation  for  the  2021
financial  year. As  a  reminder,  the  2019  and  2020  comparatives  have  been  restated  compared  to  previous  publications  (where  applicable),  in
accordance with the same standard.

The Company does not have any non-current assets held for sale to be presented in the consolidated financial statement.

w)

Critical accounting estimates and assumptions

The preparation of the consolidated financial statements under IFRS requires management to make estimates, assumptions and judgments that
affect  the  reported  amounts  of  assets,  liabilities,  income  and  expenses  during  the  reporting  period.  The  Company  bases  estimates  and
assumptions  on  historical  experience  when  available  and  on  various  factors  that  it  believes  to  be  reasonable  under  the  circumstances.  The
Company’s actual results may differ from these estimates under different assumptions or conditions.

These estimates and judgments involve mainly:

the  accounting  for  collaboration  and  licensing  agreements:  the  revenue  results  primarily  from  payments  based  on  several
components  (e.g.,  upfront  payments,  milestone  payments)  received  in  relation  to  research,  collaboration  and  licensing  agreements
signed with pharmaceutical or other companies. When the Company is committed to perform R&D services, revenue is spread over
the period the Company is engaged to deliver these services, more particularly on the basis of the Company’s inputs to the satisfaction
of a performance obligation relative to the total expected inputs to the satisfaction of that performance obligation. Milestone payments
are  dependent  upon  the  achievement  of  certain  scientific,  regulatory,  or  commercial  milestones.  These  variable  payments  are
recognized when the triggering event has occurred, there are no further contingencies or services to be provided with respect to that
event, and the counterparty has no right to refund of the payment. The changes in estimate regarding the completion of the works and
the variable consideration relating to the contracts signed with customers are described in Note 13. As of December 31, 2023, given
the significant progress of the work to be performed (98.1%) and the level of budget consumption, the impact of accounting estimates
is no longer a determining factor in the calculation of revenue related to the monalizumab agreement.

the estimate of the recoverable amount of the acquired and under progress licenses: impairment tests are performed on a yearly
basis for the intangible assets which are not amortized (such as intangible assets in progress). Amortizable intangible assets are tested
for

F-33

impairment when there is an indicator of impairment. Impairment tests involve comparing the recoverable amount of the licenses to
their  net  book  value. The  recoverable  amount  of  an  asset  is  the  higher  of  its  fair  value  less  costs  to  sell  and  its  value  in  use.  If  the
carrying amount of any asset is below its recoverable amount, an impairment loss is recognized to reduce the carrying amount to the
recoverable amount. The main assumptions used for the impairment test include (a) the amount of cash flows that are set on the basis
of the development and commercialization plans and budgets approved by Management, (b) assumptions related to the achievement of
the clinical trials and the launch of the commercialization, (c) the discount rate, (d) assumptions on risk related to the development and
(e) for the commercialization, selling price and volume of sales, Any change in these assumptions could lead to the recognition of an
impairment charge that could have a significant impact on the Company’s consolidated financial statements. As of December 31, 2022,
given  the  Company's  decision  in  December  2022  to  discontinue  the  development  of  avdoralimab  in  the  indication  of  bullous
pemphigoid  supporting  the  recoverable  amount  of  the  asset  as  of  December  31,  2021  and  June  30,  2022,  the  rights  related  to  the
intangible asset have been fully impaired for the net carrying amount of the intangible asset, of €41,000 thousand, without using the
historical assumptions described above (see note 6). As a result, the Company considers that there are no longer any critical estimates
in line with intangible assets in 2022. Without any new event to be considered since then, there are therefore no longer any critical
assumptions that could call into question the recoverable amount of the asset.

Management of financial risks and fair value

The  principal  financial  instruments  held  by  the  Company  are  cash,  cash  equivalents  and  marketable  securities. The  purpose  of  holding  these
instruments is to finance the ongoing business activities of the Company. It is not the Company’s policy to invest in financial instruments for
speculative purposes. The Company does not utilize derivatives.

The principal risks to which the Company is exposed are liquidity risk, foreign currency exchange risk, interest rate risk and credit risk.

Liquidity risk

The Company’s cash management is performed by the Finance department, in charge of monitoring the day-to-day financing and the short-term
forecast and enabling the Company to face its financial commitments by maintaining an amount of available cash consistent with the maturities
of its liabilities. As of December 31, 2024, cash, cash equivalents and short-term investments were €80,770 thousand, which represents more
than a year of cash consumption.

The company's assets are fairly split between top-rated banks (S&P A+ rating).

The main characteristics of the financial instruments owned by the Company (including liquidity) are presented in Note 4.

Foreign currency exchange risk

The  Company  is  exposed  to  foreign  exchange  risk  inherent  in  certain  subcontracting  activities  relating  to  its  operations  in  the  United  States,
which have been invoiced in U.S. dollars. The Company does not currently have recurring revenues in euros, dollars or in any other currency.

The revenue denominated in U.S. dollars has represented approximately 92%, 29% and 52% of revenue in the years ended December 31, 2022,
2023  and  2024,  respectively.  Payments  in  U.S  dollars  represented  approximately  50%,  43%,  and  35%  of  the  payments  in  the  years  ended
December 31, 2022, 2023 and

F-34

2024, respectively. In order to cover this risk, the Company kept in U.S. dollars a part of the consideration received from AstraZeneca in June
2015, January 2019 and December 2020. The Company entirely kept the U.S dollars portion of the proceeds received from our Global Offering
in October 2019.

The Company’s foreign exchange policy does not include the use of hedging instruments in its current operations.

Interest rate risk

The  Company  has  very  low  exposure  to  interest  rate  risk.  Such  exposure  primarily  involves  money  market  funds  and  time  deposit  accounts.
Changes  in  interest  rates  have  a  direct  impact  on  the  rate  of  return  on  these  investments  and  the  cash  flows  generated. The  Company  has  no
credit facilities. The repayment flows of the borrowings subscribed in 2017 and the two State Guaranteed Loans obtained in 2021 and extended
in 2022, are not subject to interest rate risk.

Credit risk

The credit risk related to the Company’s cash equivalents, short-term investments and non-current financial assets is not significant in light of the
quality of the issuers. The Company deemed that none of the instruments in its portfolio are exposed to credit risk.

Fair value

The fair value of financial instruments traded on an active market is based on the market rate as of December 31, 2024. The market prices used
for the financial assets owned by the Company are the bid prices in effect on the market as of the valuation date.

Cash and cash equivalents are mainly composed of current bank accounts, interest-bearing accounts, fixed-term accounts and mutual funds units
(with short-term maturities) held with various banking institutions.

Other non-current financial assets generally include a guarantee of capital at the maturity date (which is always longer than one year). These
instruments are defined by the Company as financial assets at fair value through profit or loss and classified as non-current due to their maturity.

As  of  December  31,  2022,  2023  and  2024  the  amount  of  cash,  cash  equivalents  and  financials  assets  denominated  in  U.S.  dollars  amounted
respectively to €34,735 thousand , €20,798 thousand and €16,529 thousand

(1) In accordance with the principles described in Note 2.q, the research tax credit (Crédit d’Impôt Recherche or “CIR”) is recognized as other operating income in the year to which the eligible
research expenditure relates. The amount of CIR recognized as current receivables as of December 31, 2023 comprises the research tax credit for the 2019 and 2020 tax years, for which the
three years period has expired as of December 31, 2023. The CIR for 2019 was reimbursed in February 2024 for an amount of €16,737 thousands. Repayment of the 2020 CIR was reimbursed
in July 2024 in the amount of €12,755 thousand euros. As a reminder, the Company has already benefited from the reimbursement of the CIR for the 2021 tax year during 2022 for an amount
of €10,302 thousand euros and of the CIR for the 2022 tax year during 2023 for an amount of €9,167 thousand euros. These amounts were received by the Company on November 16, 2022 and
July 21, 2023 respectively. As the CIR 2023 was subject to a financing arrangement 95% of its nominal value was cashed in December 2024. The accounting analysis concluded to the
derecognition of the CIR 2023 receivables as per described in the Accounting policy. The 5% withheld by the financing organization will be released at the end of the 3-year period, i.e. on
December 31, 2027, provided that the amount is not challenged by the tax authorities. The amount of €490 thousand has therefore been reclassified under non-current financial assets (see note
4).The amount of €7,464 thousand recognized in non-current receivables corresponds to the CIR for the 2024 tax year following the fact that the Company no longer met the eligibility criteria
for the SME status as of December 31, 2024. Thus, the CIR for the 2024 represented a non-current receivable which will in principle be offset against the French corporate income tax due by
the Company with respect to the three following years, or refunded if necessary upon expiry of such a period.

(2) As of December 31 2024, December 31, 2023, and December 31, 2022 the prepaid expenses includes amounts of €754 thousand, €1,005 thousand and €1,256 thousand, respectively, relating to
the guarantee fees in line with the two State Guaranteed Loans from Société Générale and BNP Paribas. Following the extension of these two loans repayment for an additional period, the full
amount of the guarantee fee over the additional five-year period has been recognized as an operating expense in 2022. As of December 31, 2023, an adjustment is made through the prepaid
accounts to reflect the fact that the expenses are related to the fiscal year (see note 9).

(3) As of December 31, 2024, the amount breaks mainly down as receivables from AstraZeeca for an amount of 644k€ As of December 31, 2023, the amount is mainly comprised of invoice of
€15,000 thousand issued in December 2023 following the exercise of the license option by Sanofi. This amount was collected by the Company in January 2024.As a reminder, as of December
31,  2022,  the  amount  is  entirely  comprised  of  the  receivables  from  AstraZeneca  for  an  amount  of  €1,775  thousand  and  €1,303  thousand  in  line  with  the  performance  of  research  and
development services under the monalizumab and IPH5201 collaboration agreements, respectively.

(4) At 31 December 2024, advances had been paid to suppliers. These advances will be deducted from subsequent payments in accordance with the terms of the contracts.

Trade receivables and others have payment terms of less than one year. No valuation allowance was recognized on trade receivables and others
as the credit risk of each of debtors was considered as not significant.

(1) As  of  December  31,  2022,  this  amount  corresponds  to  the  additional  payment  made  to  Orega  Biotech  in  October  2022  for  the  rights  relating  to  IPH5201,  following  the  amendment  to  the
collaboration and license option agreement IPH5201 concluded with AstraZeneca in October 2018 and the announcement by the Company on June 3, 2022, of the progression of IPH5201
towards a Phase 2 study in lung

F-38

cancers of which the Company will be a sponsor. As of December 31, 2023, this amount corresponds to the additional payment made to Orega Biotech in July 2023 for the rights relating to
IPH5201 following the first patient dosed in the Phase 2 MATISSE clinical trial in June 2023, in accordance to the agreement signed in 2019. This additional payment is fully amortized as of
December 31,2023.

(2) As of December 31, 2022, this amount included the amortization of rights relating to monalizumab (€1,604 thousand) and IPH5201 (€587 thousand). As of December 31, 2023, this amount
includes  the  amortization  of  rights  relating  to  monalizumab  (€1,138  thousand)  and  IPH5201  (€2,000  thousand). As  of  December  31,  2024,  this  amount  includes  the  amortization  of  rights
relating to monalizumab (€416 thousand) .

(3) Following  the  Company's  decision  in  December  2022  to  stop  the  development  of  avdoralimab  in  bullous  pemphigoid  ("BP")  indication  in  inflammation,  only  indication  supporting  the
recoverable amount of the asset as of December 31, 2021 (as well that as of June 30, 2022), the rights relating to the intangible asset have been fully impaired for their net book value on the
date of the decision, i.e. €41,000 thousand (see below "Avdoralimab (IPH5401) (anti-C5aR) rights acquired from Novo Nordisk A/S')

Monalizumab rights under the 2014 monalizumab (NKG2A) Novo Nordisk agreement

At  the  agreement  inception,  acquired  rights  were  recorded  as  intangible  asset  for  an  amount  of  €7,000  thousand.  The  Company  recorded  an
additional  consideration  of  €6,325  thousand  in  2015  and  a  final  consideration  of  $15,000  thousand  (€13,050  thousand)  due  in  2018  (see
Note 1.1.a).

Since their acquisition by the Company, monalizumab rights are amortized on a straight-line basis over the anticipated residual duration of the
Phase  2  trials. At  31  December  2024,  the  Company  has  estimated  that  the  rights  associated  with  monalizumab  will  be  fully  amortized.  This
timing takes into account both the completion of certain clinical trials and changes in the estimated end dates for certain cohorts.

The  net  book  values  of  the  monalizumab  rights  were  €0  thousand  and  €416  thousand  as  of  December  31,  2024  and  December  31,  2023,
respectively.

IPH5201 (Anti-CD39) rights acquired from Orega Biotech; Sub-licensing revenues to be paid to Orega Biotech

On  January  4,  2016,  the  Company  and  Orega  Biotech  entered  into  an  exclusive  licensing  agreement  by  which  Orega  Biotech  granted  the
Company full worldwide rights to its program of first-in-class anti-CD39 checkpoint inhibitors. The undisclosed upfront payment paid by the
Company to Orega Biotech has been recognized as an intangible asset in the consolidated financial statements for the year ended December 31,
2016.  Criteria  relating  to  the  first  development  milestone  were  reached  in  December  2016.  Consequently,  the  amount  of  this  milestone  was
recognized  as  an  intangible  asset  in  addition  to  the  initial  payment,  for  a  total  of  €1.8  million  as  of  December  31,  2023.  In  June  2019,  the
Company also paid Orega Biotech €7.0 million in relation to the anti-CD39 program. Under this agreement, the Company also paid in April and
June 2020, respectively €2.5 and €0.2 million to Orega Biotech following the first Phase 1 dosing relating to IPH5201.

This asset was amortized on a straight-line basis since November 1, 2018 (corresponding to the effective beginning date of the collaboration)
until the date the Company expected to fulfill its commitment (end of fiscal year 2020). As a reminder, these collaboration commitments have all
been fulfilled. Thus, the rights relating to IPH5201 are fully amortized since December 31, 2020.

Orega Biotech claimed joint ownership of certain patents relating to IPH5201, which the Company disputed. The Company and Orega Biotech
resolved these claims in an arbitration proceeding, which ended in a decision rendered by the arbitral tribunal in December 2021. As a result of
this decision, the Company will be required to pay a low-teen percentage to Orega Biotech on a going forward basis of sub-licensing revenues
received by the Company pursuant to its agreement with AstraZeneca regarding IPH5201 Following this arbitral decision, the Company paid in
January 2022 an additional amount of 0.4 million euros to Orega Biotech.

The Company announced on June 3, 2022 the progress of IPH5201 towards a study of Phase 2 in lung cancer, of which the Company will be a
sponsor. In accordance with the amendment signed on June 1,

F-39

2022, the Company was eligible for a milestone payment of $5 million by AstraZeneca, received in August 2022 by the Company. In October
2022, the Company paid an additional €0.6 million to Orega Biotech.

On  June  26,  2023,  the  Company  announced  the  treatment  of  the  first  patient  in  the  Phase  2  MATISSE  trial,  conducted  in  collaboration  with
AstraZeneca and evaluating IPH5201 in early-stage lung cancer. As a consequence, the Company made an additional payment of €2.0 million to
Orega Biotech in July 2023, in accordance with the agreement signed in 2019.

Pursuant to the arbitral decision mentioned above and the potential milestone payments to which the Company may be due under the 2018 AZ
Option Agreement,  the  Company  may  also  be  obligated  to  pay  Orega  Biotech  up  to  €47  million  upon  the  achievement  of  development  and
regulatory milestones.

Avdoralimab (IPH5401) (anti-C5aR) rights acquired from Novo Nordisk A/S

At the agreement inception, an upfront payment of €40 million for acquired rights were recorded as intangible asset. As part of this agreement,
an additional amount of €1.0 million was paid in October 2020 to Novo Nordisk A / S following the launch of the first avdoralimab Phase 2 trial.
As avdoralimab is still in clinical trial, the acquired rights are classified as intangible asset in progress. They were subject to annual impairment
test. No impairment were recorded since inception.

According  to  the  agreement,  the  Company  will  pay  additional  payments  according  to  the  reach  of  specific  steps. As  of  December  31,  2024,
according to the uncertainty of these potential future payments, no liability was recognized.

Development costs incurred by the Company are recognized as research and development expenses.

During 2022 fourth quarter, the Company was informed by the sponsor of the Phase 2 clinical trial evaluating avdoralimab in inflammation in
bullous pemphigoid ("BP") indication of its decision to discontinue said trial. Consequently, the Company decided in December 2022 to stop the
development of avdoralimab in bullous pemphigoid ("BP") indication in inflammation, only indication supporting the recoverable amount of the
asset as of December 31, 2021 (as well that as of June 30, 2022).

Following  that  decision,  the  Company  applied  IAS  36  "Impairment  of  assets"  and  assessed  that  there  was  an  indication  of  impairment
sufficiently significant to result in the full impairment of the intangible asset. This depreciation was recognized with regard to the estimate of the
recoverable value of avdoralimab's intangible assets, based on expected future cash flows, as of December 2022, date of the decision. Thus, on
decision date to stop the development of avdoralimab in bullous pemphigoid ("BP") indication in inflammation, avdoralimab rights were fully
written down to their net book value, i.e €41,000 thousand.

(1) On January 5, 2022, the Company announced that it had obtained €28.7 million in non-dilutive financing in the form of two State Guaranteed
Loans from Société Générale (€20.0 million) and BNP Paribas (€8.7 million). The Company received the funds related to these two loans on
December 27 and 30, 2021 respectively. Both loans have an initial maturity of one year with an option to extend to five years from August 2022.
They  are  90%  guaranteed  by  the  French  government  as  part  of  the  package  of  measures  put  in  place  by  the  French  government  to  support
companies  during  the  COVID-19  pandemic.  In August  2022,  the  Company  has  requested  the  extension  of  these  two  loans  repayment  for  an
additional period of five years starting in 2022 and including a one-year grace period. Consequently, the Company has obtained agreements from
Société Générale and BNP Paribas. The effective interest rates applied to these contracts during the additional period are 1.56% and 0.95% for
Société  Générale  and  BNP  Paribas  loans,  respectively,  excluding  insurance  and  guarantee  fees,  with  an  amortization  exemption  for  the  entire
year 2023. During this grace period, the Company will only be liable for the payment of interest and the guarantee fees, with amortization of the
two  loans  starting  in  2024  over  a  period  of  four  years.  The  state  guarantee  fees  amounts  to  €877  thousand  and  €379  thousand  for  Société
Générale and BNP Paribas loans respectively.

(2) On July 3, 2017, the Company borrowed from the Bank “Société Générale” in order to finance the construction of its future headquarters.
This  loan  amounting  to  a  maximum  of  €15,200  thousand  will  be  raised  during  the  period  of  the  construction  in  order  to  pay  the  supplier
payments as they become due. As of December 31, 2018 and 2019, the loan was raised at an amount of €14,826 thousand.

The  loan  release  period  was  limited  to  August  30,  2019.  On  August  30,  2019,  the  Company  drew  down  the  remaining  portion  of  the
€15,200 thousand loan granted, for an amount of €13,900 thousand. The reimbursement of the capital has begun in August 30, 2019 and will
proceed until August 30, 2031 (12 years). Given the development of its portfolio and in particular the refocusing of its activities on research

F-44

and development, the Company has for the time being suspended the project to build its new head office on the land acquired in Luminy. In the
meantime, the loan will be used to finance several structuring projects (improvement of the information system, development of a commercial
platform,  development  of  additional  premises  rented,  etc.). As  of  December  31,  2024,  the  remaining  capital  of  the  loan  amounted  to  €8,894
thousand.  The  Company  authorized  collateral  over  financial  “Société  Générale”  instruments  amounting  to  €15,200  thousand.  The  security
interest  on  the  pledge  financial  instruments  will  be  released  in  accordance  with  the  following  schedule:  €4,200  thousand  in  July  2024,
€5,000 thousand in August 2027 and €6,000 thousand in August 2031. The amount of €4.2 million was actually received in July 2024.

This loan bears a fixed interest rate of 2.01% . It is subject to a covenant based on the assumption that the total cash, cash equivalents and current
and non-current financial assets are at least equal to principal as of financial year end.

(3) On March 13, 2023, the Company signed an amendment to the lease for the "Le Virage" building, reducing the surface area of the leased
premises.  The  effective  date  of  the  lease  amendment  is  March  15,  2023.  As  a  result,  and  in  accordance  with  IFRS  16,  the  impact  on  the
consolidated balance sheet at the effective date of the lease amendment is as follows: write-off of a right of use (asset) of €0.5 million and a lease
liability of €0.7 million.

French law requires payment of a lump sum retirement indemnity to employees based on years of service, the rights guaranteed by the collective
agreements and annual compensation at retirement. Benefits do not vest prior to retirement. The Company pays for this defined benefit plan. It is
calculated as the present value of estimated future benefits to be paid, applying the projected unit credit method whereby each period of service
is seen as giving rise to an additional unit of benefit entitlement, each unit being measured separately to build up the final. As a reminder, in
April 2021, the IFRIC ( or "IFRS Interpretations Committee") sent a proposal to the IAS Board (International Accounting Standards Board) to
change the way in which the liabilities for certain defined benefit plans are calculated. The IAS Board endorsed this position in June 2021. The
impacts of this change in valuation method are taken into account since 2021.

In addition, the impact of the 2023 pension reform (including the raising of the retirement age) has been recognized as a plan amendment within
the meaning of IAS 19, recognized in the income statement and balance sheet with no material impact as of December 31, 2023.

On  March  24,  2016,  the  Company  entered  into  an  internal  labor  agreement  with  the  employees  representatives  whereby  the  Company  is
committed to paying a seniority award after 15 years and 20 years of employment. This award is paid on the anniversary date. A similar award
existed for employees having a seniority of 10 years but was not booked due to its insignificant amount. As such, in 2016 the Company recorded
a provision for seniority awards and a corresponding charge included in “Personnel costs other than share-based payments” (see Note 14) other
than payments in shares. These awards meet the definition of other long-term benefits under IAS 19. This provision is determined by an external
actuary  firm  based  on  the  assumptions  disclosed  hereafter  and  amounts  to  €361  thousand  as  of  December  31,  2024  (€377  thousand  as  of
December 31, 2023).

The main actuarial assumptions used to evaluate retirement benefits are the following:

Economic assumptions

Discount rate (iBoxx Corporate AA) for retirement

Annual rate of increase in wages

Demographical assumptions

Type of retirement

Annual mobility rate

Rate of contributions

Rate of wages costs

Age at retirement

(1) In its April 2021 Update, the IFRS IC published a final agenda decision clarifying how to calculate the obligation relating to certain defined
benefit plans under which the retirement benefit is (i) contingent on the employee being employed by the entity at the time of retirement; (ii)
capped at a specified number of years of service; and (iii) linked to the employee's length of service at the date of retirement. In that decision, the
IFRS  IC  took  the  view  that  the  obligation  should  be  recognized  only  over  the  years  of  service  preceding  the  date  of  retirement  in  respect  of
which the employee generates entitlement to the benefit. The application of this decision has led to a change in accounting method, the effects of
which should be taken into account retrospectively in accordance with IAS 8. However, as the Company considers the impact of this change of
method on defined benefit obligation and the income statement to be insignificant, these impacts have not been restated for years prior to January
1, 2021. The effects of this change of method are therefore taken into account retrospectively as of January 1, 2021 in respect of 2020's and prior
years  defined  benefit  obligation.  The  adjustment  at  that  date  corresponds  to  a  reduction  in  the  2020  commitments  in  the  amount  of
€1,054 thousand. This reversal has been offset against previous reserves and retained earnings.

There is no asset covering the defined benefit obligations.

An increase/decrease of +/- 25 basis point of the discount rate would result in a decrease/increase of the total benefit obligation of €65 thousand.

The actuarial assumptions used for the provision for length-of-service awards are as follows:

• Discount rate: 3.00

• Annual rate of salary increase: 2.50

• Rate of employer contributions: 49.29

•

Employee contributions: 22.62

• Retirement age: 64 for executives, 62 for non-executives

• Mortality table: TH-TF 00-02

• Annual mobility rate: 5.70% on average

The  amounts  recognized  as  an  expense  linked  to  defined  contributions  plans  amounted  to  €1,432  thousand,  €1,283  thousand  and  €1,251
thousand in the years ended December 31, 2022, 2023 and 2024, respectively.

11) Share capital and share based payments

a)

Share capital

The  Company  manages  its  capital  to  ensure  that  the  Company  will  be  able  to  continue  as  a  going  concern  while  maximizing  the  return  to
shareholders through the optimization of the debt and equity balance.

The Company has never declared or paid any dividends on its ordinary shares. The Company does not anticipate paying cash dividends on its
equity securities in the foreseeable future and intend to retain all available funds and any future earnings for use in the operation and expansion
of its business, given our state of development.

F-48

As of December 31, 2024, the Company’s share capital amounted to €4,192,221 divided into (i) 83,830,336 ordinary shares, each with a nominal
value of €0.05, (ii) 6,494 “2016” free preferred shares, each with a nominal value of €0.05 and (iii) 7,581 “2017” free preferred shares, each with
a nominal value of €0.05, respectively fully paid up.

Share capital does not include BSAs, BSAAR,AGAs and AGAPs that have been granted to certain investors or natural persons, both employees
and non-employees of the Company, but not yet exercised.

In October 21, 2019 and December 30, 2019, the retention period for the “2016 free preferred shares” has ended. The number of ordinary shares
to which the conversion of one preferred share entitle has been determined according to the fulfillment of the performance criteria. Holders of
“2016” preferred shares” are entitled to vote at our shareholders’ meetings, to dividends and to preferential subscription rights, on the basis of the
number of ordinary shares to which they are entitled if they convert their preferred shares.

In April 3, 2021, the retention period for the "2017 free preferred shares" has ended. The number of ordinary shares to which the conversion of
one preferred share entitle has been determined according to the fulfillment of the performance criteria. According to these same performance
criteria,  the  Executive  Board  of  April  7,  2021  noted  that  the  "2017  preferred  shares"  did  not  give  right  to  any  ordinary  shares.  The  “2017
preferred  shares”  will  not  be  redeemed  by  the  Company  and  will  remain  incorporated  into  the  capital,  unless  subsequently  decided  by  the
Executive Board. As the conversion is void, the "2017 preferred shares" no longer give the right to vote at our general meetings, nor to receive
dividends.

The fair value of granted free shares is based on the closing price of the Company’s share at grant date, reduced when necessary by an estimated
turn-over rate. This estimated fair value is recognized as operating expenses on a straight-line basis over the vesting period.

Free performance shares 2019 (AGA Perf Employees 2019-1 / AGA Perf Management 2019)

Free performance shares granted in 2019 are subject to share price conditions and a vesting kicker triggered by the performance of an internal
condition, which is Lumoxiti's market penetration rate in the United States.

The fair value of these free performance shares is based on a third-party valuation report. The valuation method used to estimate the fair value of
these free performance shares is presented below:

•

Estimation of the expectation of gain associated with internal and share price conditions, made on the basis of a CAPM model of the
share price using a Monte Carlo approach;

• Adjustment of the estimation by applying expected turnover rates.

F-63

On November 7, 2022, the Executive Board determined the achievement of the performance conditions and the final vesting of the 2019 free
performance shares as of November 4, 2022. The underlying performance conditions were thus achieved at 50%. Consequently, on November 7,
2022, the Executive Board carried out the definitive acquisition of 171,550 free performance shares under the "AGA Perf Management 2019-1"
plans.

Expenses were €(181) thousand for the financial years ended December 31, 2022. Income relating to the 2022 financial year is explained by the
review of the performance conditions during the 2022 financial year with regard to the definitive achievement of the vesting. These instruments
were definitively acquired during the 2022 financial year. Consequently, no expense relating to these plans was recognized during the financial
year ended December 31,2023.

Free performance shares 2020 (AGA Perf Employees 2020-1 / AGA Perf Management 2020)

Free performance shares granted in 2020 are subject to share price conditions and two vesting kickers triggered by the performance of internal
conditions, which are :

• A commercial break-even point for Lumoxiti in the U.S. reached at the end of fiscal year 2023 (this criterion will not be met given the

return of the commercial rights notified to AstraZeneca in December 2020).

• Revenue from collaborative and licensing agreements accrued between the attribution and definitive acquisition date (excluding payment

by AstraZeneca for the first patient in Phase 3 for monalizumab), reaching $100 million.

The fair value of these free performance shares is based on a third-party valuation report. The valuation method used to estimate the fair value of
these free performance shares is presented below:

•

Estimation of the expectation of gain associated with internal and share price conditions, made on the basis of a CAPM model of the
share price using a Monte Carlo approach;

• Adjustment of the estimation by applying expected turnover rates.

performance shares as of December 31, 2023. The underlying performance conditions were thus achieved at 20%. Consequently, on December
31, 2023, the Executive Board carried out the definitive acquisition of 85,230 free performance shares under the "AGA Perf Employees 2020-1"
plans and 130,000 free performance shares under the "AGA Perf Management 2020-1" plans.

Expenses were €1,738 thousand and €1,436 thousand for the financial year ended December 31, 2022 and 2023, respectively. These instruments
were definitively acquired during the 2023 financial year. Consequently, no expense relating to these plans was recognized during the financial
year ended December 31,2024.

Free performance shares 2021 (AGA Perf Employees 2021-1 / AGA Perf Management 2021-1)

monalizumab in combination with cetuximab in patients with squamous cell carcinoma of the head and neck and previously treated with
chemotherapy).

• Obtaining positive Phase 2 results for a product in the Company's portfolio.

•

The start of a first clinical trial for a product in the Company's portfolio

The fair value of these free performance shares is based on a third-party valuation report. The valuation method used to estimate the fair value of
these free performance shares is presented below:

•

BSAAR

BSAAR  are  securities  whose  subscription  price  and  exercise  price  are  fixed  at  their  fair  value  as  determined  by  an  expert.  The  BSAAR
subscription therefore represents an investment on the part of the beneficiary. At the end of the exercise period, if they have not been exercised,
the  BSAAR  becomes  void.  The  Company  benefits  from  a  clause  called  «forcing»  making  it  possible  to  encourage  holders  to  exercise  their
redeemable equity warrants when the market price exceeds the exercise price and reaches a threshold defined in the BSAAR issuance agreement.
The Company may, then, subject to a time period for notifying holders that will permit them to exercise the BSAAR, decide to reimburse the
warrants not exercised at a unit price equal to the BSAAR acquisition price paid by its holder.

Details of BSAAR

BSAAR. The methodology used to estimate the fair value of the BSAAR is similar to the one used to estimate the fair value of the BSA, except
for the following:

Expected Term. Unlike the BSA, the Company does not have sufficient historical experience for the BSAAR. Consequently, the expected term
used for the valuation of the fair value is the legal maturity of the instrument (10 years).

No share-based payment compensation expense was recognized relating to the BSAAR since the amount paid by the beneficiaries is equal to the
fair value.

a)

Revenue recognition related to monalizumab AstraZeneca agreements and amendments

The Company identified the following promises under the monalizumab AstraZeneca agreements and amendments: (1) a non-exclusive license
related to monalizumab restricted to two applications, with an option for an exclusive license related to monalizumab including all applications,
(2)  the  performance  of  certain  initial  studies  related  to  Phases  1/2  trials,  and  participation  in  certain  studies  of  Phases  1/2  trials  and  Phase  3
clinical trials through a co-financing.

The Company considered the license has a standalone functionality and is capable of being distinct. However the Company determined that the
license is not distinct from the performance of initial studies and participation in Phase 3 clinical trials because they increased the utility of the
licensed  IP.  Thus,  the  licensed  IP,  the  performance  of  initial  studies  and  participation  in  Phase  3  clinical  trials  are  combined  into  a  single
performance obligation.

This performance obligation was considered as satisfied over time as AstraZeneca controls the licensed IP which is being enhanced during the
agreement. The revenue is recognized over time, based on the input method (costs incurred). As a result, the Company recognizes the price of the
transaction as a revenue on the basis of the progress of studies that the Company has undertaken to carry out under the agreement. Progression is
assessed following to actual costs incurred relative to the total budgeted costs to fulfill the obligation.

F-73

The  transaction  price  was  initially  estimated  to  the  initial  payment  of  $250.0  million,  less  the  amounts  that  the  Company  expected  to  pay  to
AstraZeneca for co-financing Phase 1/2 clinical studies. The additional payment of $100.0 million triggered by AstraZeneca’s exercise of the
exclusivity option was treated as a change in the price estimate of the transaction. In addition, the amendment of the contract, which modified the
scope and budget of the studies to be carried out by the Company as well as the arrangements for sharing the cost of the other studies, led to a
revision of the degree of progress and the price of the transaction. Thus, the exercise of the option and the amendment of the contract resulted in
the recognition of a favourable cumulative adjustment of €38.3 million in revenue for the year ended December 31, 2019.

The additional payment of $50.0 million triggered by the dosing of the first patient in the Phase 3 trial evaluating monalizumab was treated in
full as a collaboration commitment ("collaboration liability" in the consolidated balance sheet) in view to the commitment linked to the contract
for  the  Phase  1/2  (co-financing)  and  Phase  3  studies  (amendment  signed  in  September  2020).  Consequently,  this  additional  payment  has  no
impact on the transaction price.

In  addition  to  these  amounts, AstraZeneca  made  an  additional  payment  of  $50.0  million  (€47.7  million)  in  June  2022  and  triggered  by  the
treatment of the first patient in a second Phase 3 trial “PACIFIC-9” evaluating monalizumab in April 2022. This additional payment has been
treated  as  an  increase  of  the  collaboration  commitment  ("collaboration  liabilities"  in  the  consolidated  statements  of  financial  position)  for  an
amount  of  $36.0  million  (€34.3  million)  in  connection  to  the  Phase  3  study  co-funding  commitment  made  by  the  Company  and  notified  to
AstraZeneca  in  July  2019.  The  remaining  amount  of  $14.0  million  (€13.4  million)  has  been  treated  as  an  increase  of  the  transaction  price,
recognized in the income statement in line with the progress of the Phase 1/2 studies.

The  subsequent  milestones  and  potential  royalty  payments  are  excluded  from  the  transaction  price  due  to  the  uncertainties  of  clinical  trials
results.

The  Company  used  the  most  likely  amount  to  determine  variable  consideration.  Variable  consideration  for  cost-sharing  payments  related  to
certain studies of Phases 1/2 trials and Phase 3 clinical trials when applicable are included in the transaction price.

As a reminder, the expected payments to AstraZeneca are classified as collaboration liability in the consolidated statement of financial position.
Quarterly invoices received from AstraZeneca reduce the collaboration liability and have no impact on the consolidated statement of income.

(1) As a reminder, the increase in deferred revenue relating to monalizumab agreement between December 31, 2021 and December 31, 2022 is
explained by the additional payment of €47,687 thousand ($50,000 thousand) made by AstraZeneca in June 2022 and triggered by the launch of
the “PACIFIC-9” Phase 3 trial on April 28, 2022. This increase has led to a simultaneous increase in collaboration commitment ("collaboration
liability"- see below) of €34,335 thousand ($36,000 thousand) in accordance with the Company’s July 2019 option concerning the co-financing
of Phase 3 trials in the field of collaboration.

Revenue recognition related to IPH5201 AstraZeneca collaboration and option agreement

Revenue related to IPH5201 for the year ended December 31, 2024 is nil as for the year ended December 31, 2023, compared to revenue of
€4,677  thousand  as  of  December  31,  2022  which  resulted  from  the  entire  recognition  in  revenue  of  the  $5.0  million  (€4.7  million)  milestone
payment received from AstraZeneca following the signature on June 1, 2022 of an amendment to the initial contract signed in October 2018.
This amendment sets the terms of the collaboration following AstraZeneca’s decision to advance IPH5201 to a Phase 2 study. The Company will
conduct  the  study.  Both  parties  will  share  the  external  cost  related  to  the  study  and  incurred  by  the  Company  and AstraZeneca  will  provide
products necessary to conduct the clinical trial. Under this agreement, an amount of 2,060 thousand euros was re-invoiced in financial year 2024
(1,165 thousand euros in financial year 2023).

c)

Revenue recognition related to collaboration and license agreement signed with Sanofi in 2016

Revenues under the collaboration and license agreement signed with Sanofi in 2016 amounted to €4,000 thousand for the year ended December
31, 2024 as compared to €2,000 thousand for the year ended December 31, 2023 and €4,000 thousand for the year ended December 31, 2022. As
a reminder, the revenue recognized in 2022 resulted from Sanofi's decision to advance IPH6401/SAR'514 towards regulatory preclinical studies
for a new investigational drug. This decision triggered a milestone payment

F-75

of €3.0 million fully recognized in revenue. This amount was received by the Company on September 9, 2022. In June 2023, the first patient was
dosed in a Sanofi-sponsored Phase 1/2 clinical trial evaluating IPH6401/SAR'514 in relapsed or refractory Multiple Myeloma. As provided by
the licensing agreement signed in 2016, Sanofi made a milestone payment of €2.0 million, fully recognized in revenue since June 2023. This
amount was received by the Company on July 21, 2023. In 2024, the company announced the treatment of the first patient in the dose-extension
portion of the clinical trial evaluating SAR443579/IPH6101, materializing the progression of the clinical trial developed by Sanofi towards phase
2 in various blood cancers. The decision triggered a milestone payment to Innate of 4 million euros recognized in income at June 30, 2024 and
collected on May 17, 2024.

d) Revenue recognition related to Sanofi research collaboration and licensing agreement (2022)

On January 25, 2023, the Company announced the expiration of the waiting period under the Hart-Scott-Rodino (HSR) Antitrust Improvements
Act  of  1976  and  the  effectiveness  of  the  licensing  agreement  as  of  January  24,  2023.  Consequently,  under  the  terms  of  such  agreement,  the
Company  received  an  upfront  payment  of  €25,000  thousand  in  March  2023,  including  €18,500  thousand  for  the  exclusive  license,
€1,500  thousand  for  the  research  work  and  €5,000  thousand  for  the  two  additional  targets  options.  On  December  19,  2023,  the  Company
announced  that  Sanofi  had  exercised  an  option  for  a  one  of  the  two  preclinical  molecules.  This  option  exercise  also  resulted  in  a  milestone
payment  of  €15,000  thousand,  including  €13,300  thousand  in  respect  of  the  exclusive  license,  which  was  fully  recognized  in  income  as  of
December 31, 2023, and €1,700 thousand in respect of research work to be carried out by the Company. The Company considers that the licenses
granted  constitute  a  right  to  use  the  intellectual  property  granted  exclusively  to  Sanofi  from  the  effective  date  of  the  agreement. As  such,  all
upfront  payments  relating  to  the  licenses  granted  have  been  recognized  in  the  income  statement  during  financial  year  2023,  representing  an
amount of €31,800 thousand, including €18,500 thousand relating to the B7-H3 license and €13,300 thousand following the option exercised.

Income from research work is recognized in the income statement using the percentage-of-completion method.

Following Sanofi's announcement in October 2024 that it would return the rights to the second option to terminate the research collaboration,
revenue of 1,700 thousand euros was recognized in full in the income statement at December 31, 2024. Income relating to research work on the
1st license amounted to 400 thousand euros in financial year 2024.

e) Revenue recognition related to Takeda licensing agreement (2023)

On April  3,  2023,  the  Company  announced  that  it  has  entered  into  an  exclusive  license  agreement  with  Takeda  under  which  Innate  granted
Takeda exclusive worldwide rights to research and develop antibody drug conjugates (ADC) using a panel of selected Innate antibodies against
an  undisclosed  target,  with  a  primary  focus  in  Celiac  disease.  Takeda  would  be  responsible  for  the  future  development,  manufacture  and
commercialization of any potential products developed using the licensed antibodies. As such, the Company considered that the license granted
was  a  right  to  use  the  intellectual  property,  which  was  granted  fully  and  perpetually  to Takeda. The  agreement  did  not  stipulate  that  Innate's
activities  will  significantly  affect  the  intellectual  property  granted  during  the  life  of  the  agreement.  Consequently,  the  $5.0  million  (or  €4.6
million) initial payment, received by the Company in May 2023, was fully recognized in revenue since June 30, 2023. This amount was received
by the Company in May 2023.

On  July  25,  2024,  the  Company  received  a  letter  from  Takeda  terminating  the  exclusive  license  agreement  signed  on  March  31,  2023.
Termination was effective at the end of a 90 days notice period, i.e. on October 24, 2024.

For the financial years ended December 31, 2023 and 2024, the foreign exchange gains and losses mainly result from the variance of the
exchange rate between the Euro and the U.S. dollar on U.S. dollars denominated collaboration liabilities, and cash and cash equivalent and
financial assets accounts.

Unrealized losses on financial assets relate to unquoted instruments, the fair value of which is determined using level 2 measurements.

16) Income Tax

Due to the Company’s early stage of development, it is not probable that future taxable profit will be available against which the unused tax
losses can be utilized. As a consequence, net deferred tax assets are not recognized.

Management revised comparative balance sheets to offset deferred tax assets and liabilities in application of IAS12.74 for a total amount of €9.0
million,  and  €8.6  million  as  of  2023  and  2022  respectively.  These  amounts  were  determined  to  be  immaterial  to  the  prior  periods.  As  of
December 31, 2024, the balances offset amounted to €9.4 million.

TITLE II
CONTRIBUTION - SHARE CAPITAL – FORM OF SHARES - RIGHTS AND OBLIGATIONS ATTACHED TO SHARES

ARTICLE 6 – Share Capital

The share capital is set at €4,609,489.90 (four million six hundred nine thousand four hundred eighty-nine euros and ninety cents). It is divided
into  92,175,723  (ninety-two  million  one  hundred  seventy-five  thousand  seven  hundred  twenty-three)  ordinary  shares  with  a  nominal  value  of
€0.05 (zero point zero five) each, 6,494 (six thousand four hundred ninety-four) preference shares with a nominal value of €0.05 (zero point zero
five) each (hereinafter referred to as the "2016 Preference Shares"), and 7,581 (seven thousand five hundred eighty-one) preference shares with
a nominal value of €0.05 (zero point zero five) each (hereinafter the "2017 Preference Shares"), all of which are fully subscribed and paid up in
cash in their full amount.

ARTICLE 7 – Modifications of the Share Capital

I.    The share capital may be increased by either the issue of new shares or an increase of the nominal value of existing shares.

New  shares  are  paid  up  either  in  cash,  by  a  contribution  in  kind,  by  set-off  against  due  and  payable  receivables,  by  incorporation  of  profit,
reserves or issue premiums into the share capital, as a result of a merger or demerger, or further to the exercise of a right attached to securities
entitling their holder to capital, including, as the case may be, the payment of the corresponding amounts.

New shares are issued at either their nominal amount or at such amount increased by an issue premium.

A share capital increase can only be decided by an Extraordinary Meeting of Shareholders, following a report by the Executive Board containing
the information required by law.

An Extraordinary Meeting of Shareholders may, however, delegate such competence to the Executive Board pursuant to the conditions provided
by  law.  Within  the  limit  of  the  powers  so  granted  by  an  Extraordinary  Meeting  of  Shareholders,  the  Executive  Board  shall  have  the  powers
required  to  increase  the  share  capital  in  one  or  several  steps,  to  determine  the  terms  and  conditions  thereof,  to  officially  acknowledge  the
completion thereof and to make the corresponding amendments to the articles of association.

If a share capital increase is decided by a Meeting of Shareholders, it may delegate all the powers required for the completion of the operation to
the Executive Board.

If the Executive Board is acting by virtue of a delegation of power or competence, it shall prepare a supplementary report to the Ordinary
Meeting of Shareholders held following the meeting of the Executive Board at which such action is taken.

If  the  share  capital  is  increased  by  the  incorporation  of  profits,  reserves  or  issue  premiums,  the  Extraordinary  Meeting  of  Shareholders  shall
deliberate  pursuant  to  the  conditions  of  quorum  and  majority  required  for  Ordinary  Meeting  of  Shareholders.  In  such  case,  the  Meeting  of
Shareholders  may  decide  that  rights  constituting  fractional  shares  shall  be  neither  negotiable  nor  transferable  and  that  the  corresponding
securities should be sold. The proceeds of sale shall be allocated to the holders in proportion to their rights.

An  increase  in  share  capital  by  increasing  the  nominal  amount  of  shares  may  only  be  decided  by  a  unanimous  decision  of  the  shareholders,
unless it is the result of an incorporation of profits, reserves or issue premiums into the share capital.

Shareholders have a preferential right of subscription, in proportion to their shareholdings, to shares issued by way of cash contribution in order
to increase the share capital. Shares acquired pursuant to the exercise of this right shall be of the same category as that of the share from which
the aforesaid right arises. This also applies to shares resulting from the acquisition of securities other than shares.

Shareholders may dispose of all or part of their subscription rights during the subscription period. Such rights are negotiable if they are detached
from shares which are themselves negotiable. If this is not the case, then such subscription rights may be disposed of on the same terms as the
shares themselves.

Shareholders may waive their preferential right on an individual basis.

3

TRANSLATION FOR INFORMATION PURPOSES

The Extraordinary Meeting of Shareholders which decides to increase the share capital may cancel the preferential right to subscription pursuant
to the conditions and within the limits set by law, and shall make such decision following the issuance of reports of the Executive Board and the
Statutory Auditors, in accordance with the conditions determined by the law and regulations in force.

Shares which have not been subscribed for on an irreducible basis may be allocated to shareholders who may have subscribed on a reducible
basis for a greater number of shares than that to which they could have subscribed on a preferential basis, in proportion to their subscription
rights, and in any event, within the limit of their request, if the Extraordinary Meeting of Shareholders, or, in the case of delegation, the Executive
Board, expressly so decides.

If the subscriptions have not, in any respect whatsoever, covered the entire share capital increase, the Executive Board may exercise any one or
more of the options provided below, in the order it sees fit:

(i)    limit the share capital increase to the amount of the subscriptions on the dual condition that such subscriptions cover at least three quarters
of the amount of the originally determined increase, and that such option has not been expressly prohibited by the Extraordinary Meeting
of Shareholders at the time of issue;

(ii)    allocate the remaining shares unless the Extraordinary Meeting of Shareholders has decided otherwise; and

(iii)    opening the subscription to the public if this has been expressly authorised by the Extraordinary Meeting of Shareholders.

If  the  subscriptions  have  not  covered  the  entire  share  capital  increase,  or  three  quarters  of  this  increase  in  the  case  of  (i)  above,  after  such
options have been exercised, the share capital increase shall not be carried out.

However, the Executive Board may in any case automatically limit the share capital increase to the amount covered by subscriptions, if
unsubscribed shares represent less than 3% of the share capital increase.

In the case of a share capital increase with or without a preferential right of subscription, the Extraordinary Meeting of Shareholders may provide
that the number of shares may be increased within thirty days of the closure of subscriptions by up to 15% of, and at the same price as for, the
original issue.

If  the  share  capital  increase  produces  fractional  shares,  shareholders  with  insufficient  subscription  or  allocation  rights  shall  be  required
personally to acquire or dispose of the subscription rights necessary to obtain delivery of a whole number of new shares.

II.    An Extraordinary Meeting of Shareholders (or, in the case of delegation, the Executive Board) may also (subject to the rights of creditors if
relevant) authorise or decide upon a reduction of share capital for any reason and by any procedure whatsoever. A reduction in share capital
may not, in any event, derogate from the principle of equality between shareholders.

The reduction of share capital to an amount below the legal minimum can only be decided subject to the condition precedent of a share capital
increase to at least the statutory minimum, unless the Company is transformed into a company having a different corporate form. In the event
that the foregoing principle is not complied with, any interested party may ask the courts to dissolve the Company, provided however that the
dissolution of the Company cannot be ordered if, as of the date on which the court rules on the merits, the situation has been rectified.

Subject  to  the  legal  and  regulatory  provisions  in  force,  the  Company  may  not  either  subscribe  to  or  purchase  its  own  shares.  However,  if  an
Extraordinary  Meeting  of  Shareholders  has  decided  on  a  reduction  of  share  capital  for  reasons  other  than  due  to  losses,  it  can  authorise  the
Executive Board to purchase a fixed number of shares in order to cancel them.

ARTICLE 8 – Paying Up Shares

At least one quarter of the nominal value of shares subscribed for cash must be paid up on subscription together with the full amount of the issue
premium, if relevant.

The remainder must be paid up in one or more instalments, upon calls made by the Executive Board, within five years of the day on which the
share capital increase was completed.

4

TRANSLATION FOR INFORMATION PURPOSES

Subscribers will be informed of calls for funds by registered letter with confirmation of receipt sent at least fifteen days prior to the date set for
each payment.

If a shareholder does not pay the amounts due with respect to the shares for which he has subscribed, on the dates determined by the Executive
Board,  interest  will  automatically  accrue  on  such  amounts  in  favour  of  the  Company  at  the  statutory  rate  defined  in  Article  L.  313-2  of  the
Monetary and Financial Code, as of the expiry of the month following the date on which they fall due and without the need for a court petition or
formal notice. Moreover, when due payments in respect of shares have not been made within thirty days of formal notice sent to the defaulting
shareholder, such shares will no longer entitle the holder to admission to shareholders’ meeting and the right to vote in shareholders’ meetings,
and shall be deducted for the calculation of the quorum. The right to dividends and the preferential right of subscription to share capital increases
attached  to  these  shares  shall  be  suspended.  These  rights  shall  be  regained  on  payment  of  the  principal  and  interest  due  in  respect  of  the
amounts  due.  A  shareholder  can  then  request  the  payment  of  dividends  that  are  not  time-barred  and  exercise  his  preferential  right  of
subscription if the exercise period for such right has not expired.

The share capital must be fully paid up prior to any issue of additional shares to be paid up in cash.

ARTICLE 9 – Form of Shares – Administration of the Share Accounts

Ordinary shares are either in registered form or, if allowed by law, in bearer form, at the shareholder’s discretion. Fully paid-up 2016 Preference
Shares are in registered form. Fully paid-up 2017 Preference Shares are in registered form.

Ordinary  shares,  2016  Preference  Shares  and  2017  Preference  Shares  are  registered  in  individual  accounts  opened  by  the  Company  or  any
authorised intermediary, in the name of each shareholder and kept according to the conditions and procedures provided by legal and regulatory
provisions.

The Company is authorised to rely on statutory provisions, in particular Article L. 228-2 of the Commercial Code, with respect to the identification
of the holders of bearer shares and for such purpose it may at any time request the central depositary who administers the share account, to
provide the information referred to in Article L. 228-2 of the Commercial Code, in exchange for payment. The Company is therefore, in particular,
entitled  at  any  time  to  request  the  name  and  year  of  birth,  or  concerning  a  legal  person,  the  corporate  name  and  year  of  incorporation,  the
nationality and the post address and, if applicable, email address of holders of securities which give the right to vote in Meeting of Shareholders,
either immediately or in the future, as well as the number of shares held by each of them and, as the case may be, any restrictions which may
apply to the shares.
ARTICLE 10 - Transfer of Shares

Registered shares may be transferred by transfer from one account to another.

Ordinary  shares  paid  up  in  cash  are  freely  transferable  as  from  the  completion  of  the  share  capital  increase.  Ordinary  shares  received  in
exchange for contribution in kind are freely transferable as from the completion of the share capital increase, i.e. on the date of the Meeting of
Shareholders or meeting of the Executive Board, acting under delegation, which approved the contribution, in the case of an in-kind contribution
during the life of the company.

Title  to  ordinary  shares  is  transferred  by  registration  in  the  buyer’s  account,  on  the  date  and  in  accordance  with  the  conditions  provided  by
applicable law and, as the case may be, regulations.

Ordinary shares are freely transferable subject to legislative provisions. 2016 Preference Shares and 2017 Preference Shares are transferable
under the conditions set forth in Article 12 of these by-laws.

ARTICLE 11 – Crossing of Thresholds

Any natural person or legal entity referred to under Articles L. 233-7, L. 233-9 and L. 223-10 of the Commercial Code who gains possession,
directly or indirectly, alone or in concert, of a number of shares which represent a portion of the share capital or voting rights of the Company
equal  to  or  greater  than  1%  or  a  multiple  of  such  percentage,  must  inform  the  Company  of  the  total  number  of  shares,  voting  rights  and
securities granting an interest in capital or voting rights which it owns immediately or would own in the future, by registered mail with confirmation
of receipt sent to the registered office of the Company within five trading days starting from the date that the aforesaid threshold(s) were crossed.

5

TRANSLATION FOR INFORMATION PURPOSES

The obligation of information provided above also applies in the same conditions when the aforesaid thresholds are crossed downwards.

Shares or voting rights in excess of the portion which should have been declared but which have not been declared pursuant to the aforesaid
conditions,  are  stripped  of  their  rights  to  vote  at  shareholders’  meetings  for  any  meeting  held  within  two  years  following  the  date  of  the
regularisation  of  the  declaration  in  accordance  with  Article  L.  233-14  of  the  Commercial  Code,  if  failure  to  make  the  declaration  has  been
observed and if one or more shareholders holding an interest of at least 5% of the share capital of the Company make such request, recorded in
the minutes of the Meeting of Shareholders.

The foregoing obligations to declare apply in addition to the threshold crossing declarations provided by legal or regulatory provisions in force.

ARTICLE 12 - Rights and Obligations attached to Shares

The share capital of the Company is divided between ordinary shares, 2016 Preference Shares and 2017 Preference Shares.

I. Rights attached to ordinary shares, 2016 Preference Shares and 2017 Preference Shares

Without prejudice to the rights attached to 2016 Preference Shares and 2017 Preference Shares, each ordinary share entitles to a portion of the
corporate profits and assets in proportion to the portion of share capital that it represents.

In  addition,  each  ordinary  share  gives  the  right  to  vote  and  be  represented  at  General  Meetings  of  Shareholders  pursuant  to  the  conditions
provided by law and in these articles of association. Ordinary shares, 2016 Preference Shares and 2017 Preference Shares (including shares of
the Company that might be allocated for free in the framework of a capital increase through the incorporation of reserves, issue premiums or
profits) do not grant a double voting right pursuant to Article L. 22-10-46 of the French Commercial Code.

Shareholders  holding  ordinary  shares,  2016  Preference  Shares  and  2017  Preference  Shares  are  only  liable  up  to  the  nominal  amount  of  the
shares which they hold and any request for funds beyond that amount is prohibited.

Ownership  of  ordinary  shares,  2016  Preference  Shares  and  2017  Preference  Shares  automatically  implies  agreement  to  be  bound  by  the
Company’s by-laws and the decisions of the General Meeting of Shareholders.

The  heirs,  creditors,  successors  or  other  representatives  of  the  shareholder  holding  ordinary  shares,  2016  Preference  Shares  or  2017
Preference  Shares  cannot  request  seals  to  be  placed  on  the  Company’s  assets  and  securities  or  request  their  distribution  or  sale  by  public
auction,  or  to  interfere  with  its  management.  In  order  to  exercise  their  rights,  they  should  rely  on  company  records  and  the  decisions  of  the
General Meeting of Shareholders.

Whenever it is necessary to hold several ordinary shares, 2016 Preference Shares or 2017 Preference Shares in order to exercise a right of any
kind,  in  the  case  of  an  exchange,  regrouping  or  allocation  of  securities,  or  further  to  a  share  capital  increase  or  decrease,  merger  or  other
corporate transaction, holders of single shares or of less than the number of shares so required will only be able to exercise such right if they
themselves collect and, as the case may be, purchase or sell, the required number of securities.

However, the Company may, in the case of an exchange of securities further to a merger or demerger, a share capital reduction, the regrouping
or division and mandatory conversion of bearer into registered shares, or the distribution of securities deducted from reserves or in connection
with a share capital reduction, or the distribution or allocation of free shares, pursuant to a decision of the Executive Board, sell any securities in
respect  of  which  the  persons  entitled  thereto  have  not  requested  delivery  subject  to  having  carried  out  the  publicity  formalities  provided  by
regulations at least two years beforehand.

As from the date of such sale, the prior securities or rights to distribution or allocation shall be cancelled as and when required, and their holders
shall only be entitled to the allocation of the net proceeds of sale of unclaimed securities.

II. 2016 Preference Shares

A. Rights attached to 2016 Preference Shares

6

TRANSLATION FOR INFORMATION PURPOSES

2016  Preference  Shares  and  the  rights  of  holders  thereof  are  governed  by  the  applicable  provisions  of  the  French  Commercial  Code,  in
particular Articles 228-11 et seq. thereof.

The maximum number of 2016 Preference Shares that may be allocated is 7,500 shares.

Only the 2016 Preference Shares convertible into ordinary shares pursuant to the terms and conditions specified below benefit from a dividend
and are entitled to the reserves, applicable only from the date at which they become convertible. The 2016 Preference Shares that have become
convertible  will  bear  rights  as  from  the  first  day  of  the  financial  year  preceding  the  financial  year  during  which  they  become  convertible.  The
amount of the dividend (and, if applicable, of the portion of the reserves) to which each 2016 Preference Shares entitles is equal to the amount
due  in  respect  of  an  ordinary  share,  multiplied  by  the  number  of  ordinary  share  that  can  be  received  from  the  conversion  of  each  2016
Preference Shares.

2016 Preference Shares give no preferential subscription right to any capital increase or any operation granting a right on ordinary shares.

In  the  event  of  an  operation  taking  place  before  the  2016  Preference  Shares  are  converted  pursuant  to  paragraph  II.B  below,  the  conversion
ratio will be adjusted pursuant to the provisions of Article L. 228-99, Paragraph 2, 3° and Paragraph 5 of the French Commercial Code.

With regards to the ownership of corporate assets, a 2016 Preference Shares gives right to a portion of the liquidation surplus in proportion to
the portion of share capital that it represents.

Only the 2016 Preference Shares convertible into ordinary shares pursuant to the terms and conditions specified below grant the right to vote in
the ordinary and extraordinary general meetings of holders of ordinary shares, applicable only from the date at which they become convertible.
The number of voting rights granted by each 2016 Preference Share is equal to the number of ordinary shares that can be received from the
conversion of each 2016 Preference Share.

2016  Preference  Shares  grant  the  right  to  vote  in  the  special  meetings  of  holders  of  2016  Preference  Shares.  Holders  of  2016  Preference
Shares are grouped into a special meeting for any proposed modification of the rights attached to 2016 Preference Shares. In addition, pursuant
to  the  provisions  of  Article  L.  228-17  of  the  French  Commercial  Code,  any  proposed  merger  or  demerger  of  the  Company  in  which  2016
Preference  Shares  cannot  be  exchanged  for  shares  with  equivalent  particular  rights  will  be  subject  to  the  approval  of  any  relevant  special
meeting.

Special meetings can only make valid decisions if the holders of 2016 Preference Shares that are present or represented hold at least, when
convened for the first time, one third, and when convened for the second time, one fifth of the 2016 Preference Shares carrying the right to vote.
If  the  capital  is  modified  or  adjusted,  the  rights  of  holders  of  2016  Preference  Shares  are  adjusted  so  that  their  rights  may  be  maintained
pursuant  to Article  L.  228-99  of  the  French  Commercial  Code. The  other  rights  attached  to  2016  Preference  Shares  are  specified  in  the  next
paragraph.

B. Conversion of 2016 Preference Shares into ordinary shares

The issuance of 2016 Preference Shares may only be decided in the framework of an allocation of free shares in favour of the employees and/or
executive officers of the Company, pursuant to the provisions of Articles L. 225-97-1 and L. 22-10-59 and seq. of the French Commercial Code.

2016  Preference  Shares  will  be  definitively  acquired  by  the  beneficiaries  after  an  acquisition  period  of  one  year  from  their  allocation  by  the
Executive Board and subject to the beneficiary’s presence in the Company or its consolidated subsidiaries as an employee, executive officer or
member of an executive or supervisory body or, if applicable, of the equivalent thereof in foreign law. The “Acquisition Date” is defined as the
end of the acquisition period of the Preference Shares.

However, in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4
of  the  French  Social  Security  Code  (or  the  equivalent  thereof  in  an  applicable  foreign  law),  the  2016  Preference  Shares  will  be  allocated
definitively prior to the Acquisition Date.

The 2016 Preference Shares become convertible in ordinary shares, either new or existing at the Company’s option, after the above-mentioned
one-year vesting period from their allocation by the Executive Board, followed by a two-year retention period from the definitive allocation (the
“Retention Period”), under the conditions set forth in Paragraphs 2 to 10 below. The “Expiry Date of the Retention Period” is defined as the
end of the Retention Period.

However, in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4
of the French Social Security Code (or the equivalent

7

TRANSLATION FOR INFORMATION PURPOSES

thereof in an applicable foreign law), the 2016 Preference Shares will be allocated definitively prior to the Acquisition Date.

1. As  from  the  first  anniversary  date  of  the Acquisition  Date,  2016  Preference  Shares  will  be  freely  transferable  to  a  credit  institution  in  the

framework of a pledge agreement.

Pursuant to the provisions set forth in the Article L. 225-197-1 I., Paragraph 6 of the French Commercial Code, the 2016 Preference Shares
will be freely transferable in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth
by Article L. 341-4 of the French Social Security Code, regardless of whether such invalidity occurs before or after the Acquisition Date.

2. 2016 Preference Shares may only be converted for a conversion period of six years and six months from the Expiry Date of the Retention

Period (the “Conversion Period”).

3. During the Conversion Period, each holder of 2016 Preference Shares will have the right to convert each of his 2016 Preference Shares in
ordinary  shares,  either  new  or  existing  (at  the  Company’s  option).  The  number  of  ordinary  shares  to  which  the  conversion  of  one  2016
Preference Share will entitle will be equal to the sum of (i) a number of ordinary shares determined according to the fulfilment of an internal
condition  (the  “Internal  Condition”)  and  a  market  condition  as  defined  below  ((the  “Market  Condition”)  (together  the  “Performance
Criteria”).

The fulfilment of the Performance Criteria will give the right to convert each 2016 Preference Share in a maximum of 200 ordinary shares,
i.e. a maximum of 100 ordinary shares under the Internal Condition and a maximum of 100 ordinary shares under the Market Condition.

It is specified that this conversion ratio thus determined will be adjusted in order to take into account the shares to be issued to preserve the
rights  of  holders  of  securities  or  other  rights  giving  access  to  the  share  capital  and  holders  of  2016  Preference  Shares  under  legal  and
statutory requirements and Paragraph II. above.

4. The Internal Condition in order to calculate the number of 2016 Preference Shares that can be converted will be determined as a function of

the highest of the following two alternative criteria:

a) The first criterion is a function of the consolidated collected turnover of the Company relating to a present or future partnership or

licensing agreement, cumulated over the period from 1 July 2016 to 30 June 2019 (the “Cash Revenues”):

(i)

(ii)

(iii)

If the Turnover is strictly inferior to 50 million euros, the conversion ratio under the Internal Condition will be equal to 0;

If  the Turnover  is  superior  or  equal  to  50  million  euros  and  inferior  to  150  million  euros,  the  conversion  ratio  under  the
Price Condition will be equal to :

[(Turnover-50)/100]×100

If the Cash Revenues are equal or superior to 150 million Euros, the conversion ratio under the Internal Condition will be
equal to 100;

b) The second criterion is a function of the maturity of the portfolio of drug candidates developed by the Company during the three years
before  the  Expiry  Date  of  the  Retention  Period.  “Drug  candidates  developed  by  the  Company”  mean  Lirilumab,  Monalizumab  and
IPH4102. For each of these products:

(iv)

(v)

(vi)

In the event of the authorization by the competent regulatory authority the United States or in Europe for the Company or
one  of  its  partners  to  carry  out  a  Phase  III  trial  or  a  clinical  trial  with  a  view  to  register  a  product,  the  conversion  ratio
under the Internal Condition will be equal to 50;

In the event of the authorization by the competent regulatory authority in the United States or in Europe for the Company
or  one  of  its  partners  to  carry  out  two  Phases  III  trials  or  clinical  trials  with  a  view  to  register  two  products  and/or  two
different indications for one product, the conversion ratio under the Internal Condition will be equal to 75;

In  the  event  of  an  acceptance  from  the  European  Medicines  Agency  (EMA)  in  Europe  or  the  Food  and  Drug
Administration (FDA) in the United States to

8

TRANSLATION FOR INFORMATION PURPOSES

examine a filing by the Company or one of its partners of a marketing authorization request, the conversion ratio under
the Internal Condition will be equal to 100.

5. The Market Condition in order to calculate the conversion ratio of 2016 Preference Shares into ordinary shares will be determined depending

on the stock market price of the Innate Pharma share:

The terms “Initial Price” mean the average closing price of the Innate Pharma share on Euronext Paris for the sixty trading days prior to the
Allocation Date by the Executive Board.

The  terms  “Final  Price”  mean  the  highest  average  closing  price  of  the  Innate  Pharma  share  on  Euronext  Paris  over  a  period  of  sixty
consecutive days calculated at any time during the three years prior to the Expiry Date of the Retention Period.

The terms “High Price” means the Initial Price multiplied by two.

a)

If the Final Price is strictly inferior to the Initial Price, the conversion ratio under the Market Condition will be equal to 0;

b)

If the Final Price is between (i) a value equal or superior to the Initial Price and (ii) a value inferior to the High Price, the conversion ratio

By way of derogation to the above, the allocation of 2016 Preference Shares can take place after the date of their allocation by the Executive
Board  and  prior  to  the  Acquisition  Date,  in  the  event  of  invalidity  of  the  beneficiary  corresponding  to  classification  in  the  second  or  third
categories set forth by Article L. 341-4 of the French Social Security Code, at the beneficiary’s request.

The Executive Board will record the conversion into ordinary shares of the 2016 Preference Shares for which the conversion fulfils the conditions
set forth above, as well as the number of ordinary shares resulting from the conversions of 2016 Preference Shares that have taken place, and
will modify the by-laws accordingly, in particular with regards to the breakdown of shares by category. This competence may be delegated to the
Chairman of the Executive Board under the conditions set forth by law.

If the conversion of 2016 Preference Shares into ordinary shares results in a capital increase, such increase will be fully paid up at issue through
the incorporation of reserves, profits or issue premiums for the corresponding amount.

Shareholders will be informed of the conversions having taken place by the reports of the Executive Board and Statutory Auditors pursuant to
Article R. 228-18 of the French Commercial Code. These supplementary reports will be made available to the shareholders at the Company’s
registered office as from the date on which each meeting is convened.

III. 2017 Preference Shares

A. Rights attached to 2017 Preference Shares

2017  Preference  Shares  and  the  rights  of  holders  thereof  are  governed  by  the  applicable  provisions  of  the  French  Commercial  Code,  in
particular Articles 228-11 et seq. thereof.

The maximum number of 2017 Preference Shares that may be allocated is 12,500 shares.

From  their  definitive  acquisition  until  the  date  at  which  they  become  convertible,  the  2017  Preference  Shares  grant  the  right  to  vote  in  the
ordinary and extraordinary general meetings of holders of ordinary shares on the basis of one voting right per 2017 Preference Share. As from
the date on which they become convertible, the number of voting rights to which each 2017 Preferred Share entitles the holder becomes equal to
the number of ordinary shares to which the conversion of each 2017 Preferred Share entitles the holder.

2017  Preference  Shares  grant  the  right  to  vote  in  the  special  meetings  of  holders  of  2017  Preference  Shares.  Holders  of  2017  Preference
Shares are grouped into a special meeting for any proposed modification of the rights attached to 2017 Preference Shares. In addition, pursuant
to  the  provisions  of  Article  L.  228-17  of  the  French  Commercial  Code,  any  proposed  merger  or  demerger  of  the  Company  in  which  2017
Preference  Shares  cannot  be  exchanged  for  shares  with  equivalent  particular  rights  will  be  subject  to  the  approval  of  any  relevant  special
meeting.

Special meetings can only make valid decisions if the holders of 2017 Preference Shares that are present or represented hold at least, when
convened for the first time, one third, and when convened for the second time, one fifth of the 2017 Preference Shares carrying the right to vote.

From their definitive acquisition until the date at which they become convertible, the 2017 Preference Shares benefit from a dividend and are
entitled to the reserves. The amount of the dividend (and, if applicable, of the portion of the reserves) to which each 2017 Preference Shares
entitles is equal to the amount due in respect of an ordinary share. To this end, the 2017 Preference Shares will bear rights as from the first day
of the financial year preceding the financial year during which they are definitively acquired. As from the date at which they become convertible,
the  amount  of  the  dividend  (and,  if  applicable,  of  the  portion  of  the  reserves)  to  which  each  2017  Preference  Shares  entitles  is  equal  to  the
amount due in respect of an ordinary share, multiplied by the number of ordinary share that can be received from the conversion of each 2017
Preference Shares.

With regards to the ownership of corporate assets, a 2017 Preference Shares gives right to a portion of the liquidation surplus in proportion to
the portion of share capital that it represents.

2017 Preference Shares give preferential subscription rights to any capital increase or any operation granting a right on ordinary shares, on the
basis of one preferential subscription right per 2017 Preferred Share.

In the event of a capital depreciation or reduction, a change in the distribution of profits, an allocation of free shares, or the incorporation into the
capital  of  reserves,  profits  or  share  premiums,  distribution  of  reserves  or  any  issue  of  capital  securities  or  securities  giving  the  right  to  the
allocation of capital securities with a subscription right reserved for shareholders before the 2017 Preferred Shares are

10

TRANSLATION FOR INFORMATION PURPOSES

convertible  under  the  conditions  provided  below,  the  conversion  ratio  will  be  adjusted  to  take  into  account  this  operation  pursuant  to  the
provisions of Article L. 228-99, Paragraph 2, 3° and Paragraph 5 of the French Commercial Code.

B. Conversion of 2017 Preference Shares into ordinary shares

The issuance of 2017 Preference Shares may only be decided in the framework of an allocation of free shares in favour of the employees and/or
executive officers of the Company, pursuant to the provisions of Articles L. 225-97-1 and L. 22-10-59 and seq. of the French Commercial Code.

2017  Preference  Shares  will  be  definitively  acquired  by  the  beneficiaries  after  an  acquisition  period  of  one  year  from  their  allocation  by  the
Executive Board and subject to the beneficiary’s presence in the Company or its consolidated subsidiaries as an employee, executive officer or
member of an executive or supervisory body or, if applicable, of the equivalent thereof in foreign law. The “Acquisition Date” is defined as the
end of the acquisition period of the 2017 Preference Shares.

However, in the event of invalidity of the beneficiary corresponding to classification in the second or third categories set forth by Article L. 341-4
of  the  French  Social  Security  Code  (or  the  equivalent  thereof  in  an  applicable  foreign  law),  the  2017  Preference  Shares  will  be  allocated
definitively prior to the Acquisition Date. In the event of the death of the beneficiary, in accordance with the provisions of Article L. 225-197-3 of
the  French  Commercial  Code,  the  heirs  or  successors  of  the  beneficiary  may,  if  they  so  wish,  request  the  definitive  allocation  of  the  2017
Preferred Shares to them within six months of the date of death. In the event of retirement, the beneficiaries will retain their right to the definitive
allocation of the 2017 Preferred Shares although they are no longer bound by an employment contract.

1.
The 2017 Preference Shares become convertible in ordinary shares, either new or existing at the Company’s option, after the above-
mentioned  one-year  vesting  period  from  their  allocation  by  the  Executive  Board,  followed  by  a  two-year  retention  period  from  the  definitive
allocation (the “Retention Period”), under the conditions set forth in Paragraphs 2 to 13 below. The “Expiry Date of the Retention Period” is
defined as the end of the Retention Period.

As an exception to the above, in the event of a public tender or exchange offer, the final results of which are announced no later than the Expiry
Date of the Retention Period as defined above, the 2017 Preferred Shares will become convertible no later than (i) the first anniversary of the
Definitive Allocation (if such an offer occurs before such anniversary and in such a way that the Retention Period lasts at least one year), or (ii)
the date of announcement of the final results of such an offer (if such an offer occurs after the anniversary) (the "Amended Expiry Date of the
Retention Period").

2.
framework of a pledge agreement.

As from the first anniversary date of the Acquisition Date, 2017 Preference Shares will be freely transferable to a credit institution in the

Pursuant to the provisions set forth in the Article L. 225-197-1 I., Paragraph 6 of the French Commercial Code, the 2017 Preference Shares will
be  freely  transferable  in  the  event  of  invalidity  of  the  beneficiary  corresponding  to  classification  in  the  second  or  third  categories  set  forth  by
Article L. 341-4 of the French Social Security Code, regardless of whether such invalidity occurs before or after the Acquisition Date.

In the event of the beneficiary's death, whether during the vesting period or the Retention Period, his heirs will no longer be required to comply
with  this  non-transferability  commitment,  so  that  the  2017  Preferred  Shares  for  which  they  have  requested  the  definitive  allocation  will  freely
become transferable.

2017  Preference  Shares  may  only  be  converted  for  a  conversion  period  of  six  years  and  six  months  from  the  Expiry  Date  of  the
3.
Retention  Period  (the  “Conversion  Period”),  provided  however  that  in  the  event  of  a  public  tender  or  exchange  offer  whose  final  results  are
announced no later than the Expiry Date of the Retention Period, the Conversion Period shall commence from the Amended Expiry Date of the
Retention Period for such a period that, together with the Retention Period, it represents a total duration of eight years and six months from the
Acquisition Date.

4.
During the Conversion Period, each holder of 2017 Preference Shares will have the right to convert each of his 2017 Preference Shares
in  ordinary  shares,  either  new  or  existing  (at  the  Company’s  option).  The  number  of  ordinary  shares  to  which  the  conversion  of  one  2017
Preference Share will entitle will be equal to a number of ordinary shares determined according to the fulfilment of a market condition as defined
below (the “Market Condition”).

on the relative performance of the Innate pharma share.

The Market Condition in order to calculate the conversion ratio of 2017 Preference Shares into ordinary shares will be determined based

The term “Initial Price” means the average closing price of the Innate Pharma share on Euronext Paris for the sixty trading days prior to the date
of the General Meeting.

The  term  “Final  Price”  means  (i)  the  highest  average  closing  price  of  the  Innate  Pharma  share  on  Euronext  Paris  over  a  period  of  sixty
consecutive days, calculated at any time during the twelve months prior to the Expiry Date of the Retention Period, or (ii) in the event of a public
tender or exchange offer whose final results are announced no later than the Expiry Date of the Retention Period, the price at which this public
tender offer is made (or, in the case of a public exchange offer only, the price by transparency by applying the exchange ratio to the closing price
of the bidder's share on the day before the Amended Expiry Date of the Retention Period).

a) If the Final Price is inferior or equal to the Initial Price, the conversion ratio will be equal to 0;

b) If the Final Price is comprised between the Initial Price and € 30, the conversion ratio will be equal to:

100 x [(Final Price – Initial Price) / (30 – Initial Price)], rounded up to the nearest whole number

c) If the Final Price is equal or superior to € 30, the conversion ratio will be equal to 100.

However, if between the date of the General Meeting and the Expiry Date of the Retention Period (or, as the case may be, the Amended Expiry
Date of the Retention Period), one of the Reference Indexes (as defined below) were to experience a Significant Variation (as defined below),
then the Executive Board will have the possibility to adjust the Initial Price and/or the Final Price to neutralize the exogenous impact of such a
Significant  Variation.  The  Executive  Board  shall,  in  this  case,  appoint  a  recognized  independent  expert  to  assist  the  Executive  Board  in  the
determination of such adjustments.

The term “Reference Indexes” means the following stock market indexes: SBF 120, CAC 40, Next Biotech and NBI (NASDAQ Biotechnology
Index). If one of these indexes were to be no longer available, the Executive Board can choose a replacement index.

The term “Significant Variation” means one or the other of the following events for the relevant index:

-

-

the average of the closing value for the index over the sixty consecutive trading days prior to the Expiry Date of the Retention Period (or, as
the case may be, the Amended Expiry Date of the Retention Period) is inferior or equal to 90% of the average of the closing value for the
index over the sixty consecutive trading days prior to the General Meeting ;

the  average  of  the  closing  value  for  the  index  over  a  sixty  consecutive  trading  days  period  at  any  time  between  the  date  of  the  General
Meeting and the Expiry Date of the Retention Period (or, as the case may be, the Amended Expiry Date of the Retention Period), is inferior or
equal to 80% of the average of the closing value for the index over another sixty consecutive trading days period at any time between the
date of the General Meeting and the Expiry Date of the Retention Period (or, as the case may be, the Amended Expiry Date of the Retention
Period).

to  Paragraph  III  A.  above,  are  subject  to  the  condition  of  the  beneficiary’s  presence  in  the  Company  or  its  consolidated  subsidiaries  as  an
employee, an executive officer or a member of an executive or supervisory body or, if applicable, of the equivalent thereof in foreign law as at the
Expiry Date of the Retention Period (or, as the case may be, the Amended Expiry Date of the Retention Period). In the event that such condition
ceases  to  be  fulfilled,  the  Company  may  proceed  at  any  moment  to  the  redemption  of  2017  Preference  Shares  in  the  conditions  set  forth  in
Paragraph  8.  below.  It  is  specified  that  the  provisions  of  this  paragraph  do  not  apply  if  the  presence  of  the  beneficiary  in  the  Company  or  its
consolidated subsidiaries ceases due to death, invalidity or retirement.

Co-owners of shares must arrange to be represented vis-a-vis the Company by one of them only, who will be considered as the sole holder, or
by a sole agent. In the case of disagreement, a sole agent may be appointed by the courts at the request of the most diligent co-owner.

Unless  the  Company  has  been  notified  of  an  agreement  to  the  contrary,  usufruct  shareholders  validly  represent  bare  owners  vis-à-vis  the
Company.  The  right  to  vote  is  held  by  the  usufruct  shareholder  in  Ordinary  Meeting  of  Shareholders  and  by  the  bare  owner  in  Extraordinary
Meeting of Shareholders.

Unless  otherwise  agreed  by  the  parties,  where  shares  are  encumbered  by  a  usufruct  interest,  the  preferential  right  to  subscription  attached
thereto is held by the bare owner.

TITLE III
COMPANY MANAGEMENT AND SUPERVISION

ARTICLE 14 – Management Structure

The Company is managed by an Executive Board which exercises its duties under the supervision of a Supervisory Board.

ARTICLE 15 – Composition of the Executive Board

I.    The Executive Board consists of at least two members and five members at most.

13

TRANSLATION FOR INFORMATION PURPOSES

II.    Members of the Executive Board are appointed by the Supervisory Board.

The members of the Supervisory Board appoint one of the members of the Executive Board as Chairman of the Executive Board for the duration
of his term of office as a member of the Executive Board. The Chairman of the Executive may be dismissed by the Supervisory Board.

Members of the Executive Board must be natural persons, failing which the appointment shall be null and void. They may be chosen from non-
shareholders. They may be French nationals or of foreign nationality.

Members of the Executive Board may be dismissed by the Supervisory Board of the Meeting of Shareholders. They may resign at any time.

Each member of the Executive Board shall be less than seventy years of age. If during their term of office this age limit is reached, the duties of
the member concerned shall end at the Ordinary General Meeting following their birthday.

If a member of the Executive Board has entered into an employment contract with the Company, his dismissal, resignation or the expiry of his
term of office as a member of the Executive Board will not cause such contract to be terminated.

The Executive Board is appointed for a term of three years. If a post is vacant, the Supervisory Board must make an appointment to fill the post
within two months.

However, the terms of office of the members of the Executive Board who were duly appointed for six years by the Supervisory Board of 13 June
2005, pursuant to the provisions of the articles of association which were then applicable, shall continue to the end of their initial term and be
renewed at the annual meeting of shareholders called to decide on the accounts of the financial year closing 31 December 2010.

The  replacement  is  appointed  for  the  remaining  term  until  the  renewal  of  the  Executive  Board.  Members  of  the  Executive  Board  may  be
reappointed.

The procedure for and amount of the remuneration of each of the members of the Executive Board is set out in the instrument appointing them.

III.    No member of the Executive Board may be a member of the Supervisory Board, the Sole Chief Executive Officer or the Chairman of the
Executive Board of more than one other corporation whose registered office is in metropolitan France.

Executive  Board  membership  may  only  be  combined  with  another  corporate  office  in  another  company  in  accordance  with  the  statutory  and
regulatory restrictions in force.

IV.    The Executive Board meets as often as necessary in the interests of the Company and at least once a quarter, convened by its Chairman
or an Executive Board member delegated to such effect, at the place decided by the person convening the meeting.

In order for deliberations to be valid, the three-quarters of the members of the Executive Board must be physically present. However, members
of the Executive Board who attend Executive Board meetings by video-conference or any other means of telecommunication in compliance with
the statutory and regulatory provisions applicable to corporations with a Board of Directors management structure, are deemed to be present.

Any member of the Executive Board may be represented by another member of the Executive Board at the meetings of the Executive Board or
take part in an Executive Board meeting by video-conference or any other means of telecommunication as referred to above. Each member of
the Executive Board may receive only one proxy.

Decisions are made by a majority of those present and represented. Each member has one vote. In case of equality of expressed votes either in
favour or against a decision (abstention are not took into account), the Chairman of the Executive Board has a casting vote.

At each meeting, the Executive Board may appoint a secretary who may be chosen from outside the members of the Executive Board.

V.    The deliberations of the Executive Board are recorded in minutes placed or bound in a special registry.

The records are signed by the Chairman and by a member of the Executive Board who is present at the meeting, or by two of the members
present.

14

TRANSLATION FOR INFORMATION PURPOSES

When the Executive Board has to provide evidence of its deliberations, copies of extracts of the minutes to be submitted in evidence shall be
certified by the Chairman or by a member of the Executive Board delegated for this purpose. Following dissolution of the Company, they are
certified by one of the liquidators or the sole liquidator.

ARTICLE 16 - Powers of the Executive Board

I.    The Executive Board has the widest of powers to act in all circumstances in the name of the Company. It exercises its powers within the
scope  of  the  corporate  purposes,  subject  to  the  powers  which  are  expressly  granted  by  law  to  the  Supervisory  Board  and  the  Meeting  of
Shareholders, and, as the case may be, within the limit of the restrictions on powers decided by the Supervisory Board.

In its relations with third parties, the Company is bound by the actions of the Executive Board even where these are outside of the scope of the
corporate purposes, unless it proves that the third party was aware that the actions exceeded such purposes or if it could not have failed to be
aware of this in view of the circumstances; publication of the articles of association not in itself constituting sufficient evidence thereof.

The Chairman of the Executive Board, or, as the case may be, the Chief Executive Officer, , represents the Company in its relations with third
parties. The Supervisory Board may grant the same authority to represent the Company to one or more other Executive Board members, who in
that case will be referred to as managing directors. The Chairman of the Executive Board and the managing director (s), if any, may designate
any agent which they choose to exercise specific powers.

II.    The Executive Board presents a report to the Supervisory Board at least once every quarter.

The Executive Board presents the annual financial statements to the Supervisory Board within three months of the end of each financial year, for
the purposes of verification and supervision.

It must also provide the Supervisory Board with the management report which it will present to the Annual Meeting of Shareholders.

III.    The Chairman of the Executive Board represents the Company in its relations with third parties.

IV.        Members  of  the  Executive  Board  may  allocate  corporate  management  tasks  among  themselves,  with  the  approval  of  the  Supervisory
Board. However, such distribution may not, under any circumstances, cause the Executive Board to lose its collegial nature with respect to the
management of the Company.

ARTICLE 17 – Composition of the Supervisory Board

I.        The  Executive  Board  is  supervised  by  a  Supervisory  Board  composed  of  a  minimum  of  three  members  and  a  maximum  of  eighteen
members, subject to the exceptions provided by law in such respect in the event of a merger.

Members of the Supervisory Board are appointed from among natural persons or legal entities that are shareholders by the Ordinary Meeting of
Shareholders, which may dismiss them at any time. However, in the case of a merger or demerger, an Extraordinary Meeting of Shareholders
may appoint the members of the Supervisory Board.

No member of the Supervisory Board may be a member of the Executive Board.

The number of the members of the Supervisory Board who have reached seventy (70) years of age may not be greater than one third of the
members of the Supervisory Board in office. Where such limitation concerning the age of members of the Supervisory Board is exceeded, the
most elderly member of the Supervisory Board is deemed to have automatically resigned.

II.        The  duration  of  the  terms  of  office  of  the  members  of  the  Supervisory  Board  is  two  years.  It  expires  at  the  close  of  the  Meeting  of
Shareholders called to decide on the financial statements for the preceding year and which is held during the year in which their appointment
expires.

Members of the Supervisory Board may be reappointed.

They may be dismissed at any time by an Ordinary Meeting of Shareholders.

III.    Members of the Supervisory Board may be natural persons or legal entities. Legal entities must, at the time of their appointment, designate
a permanent representative who will be subject to the

15

TRANSLATION FOR INFORMATION PURPOSES

same conditions and obligations and who will incur the same liabilities provided by law as if he were a member of the Council in his own name,
without prejudice to the joint and several liability of the legal entity he represents.

If  a  legal  entity  dismisses  its  representative,  it  must  appoint  a  replacement  at  the  same  time. This  rule  also  applies  in  the  case  of  the  death,
resignation or long-term prevention of the permanent representative from exercising his duties.

A natural person who accepts an appointment and exercises as a member of the Supervisory Board thereby has the obligation to confirm at any
time  on  oath,  that  he  satisfies  the  limitation  required  by  law  with  respect  to  the  combining  the  post  of  member  of  the  Supervisory  Board  and
member of the Executive Board of corporations.

IV.    Appointments which are made by the Supervisory Board in accordance with the foregoing are subject to ratification by the next following
Ordinary  Meeting  of  Shareholders.  If  such  appointments  are  not  ratified,  the  deliberations  made  and  actions  previously  carried  out  by  the
Supervisory Board nevertheless remain valid.

If  the  number  of  the  members  of  the  Council  becomes  less  than  the  statutory  minimum,  the  Executive  Board  must  immediately  convene  an
Ordinary Meeting of Shareholders to appoint members to complete the Council.

A  member  of  the  Supervisory  Board  appointed  to  replace  another  member  shall  only  remain  in  office  for  the  remaining  term  of  office  of  his
predecessor.

V.    Each member of the Supervisory Board must own one share in the Company.

If a member of the Supervisory Board does not own the required number of shares on the date of his appointment or if, during his term of office
he ceases to own such number, he shall be deemed to have automatically resigned if he has not rectified this situation within six months.

TITLE IV
STATUTORY AUDITORS

ARTICLE 25 - Statutory Auditors

One or more statutory auditors perform an audit of the Company, in the accordance with statutory requirements.

The  Statutory Auditors  are  appointed  by  the  Ordinary  Meeting  of  Shareholders  on  proposal  by  the  Supervisory  Board,  for  six  financial  years.
They may always be re-appointed. They may be dismissed by the aforesaid Meeting of Shareholders in the event that they commit a fault or are
prevented from carrying out their duties.

If the Meeting of Shareholders does not appoint the Statutory Auditor(s) or if one or more appointed Statutory Auditors are prevented or refuse to
carry out their duties, they, or their replacement(s), are appointed by an order of the Commercial Court with jurisdiction over the area in which the
Company is based on petition of any interested person, with the Executive Board duly convened.

The Statutory Auditor appointed by the Meeting of Shareholders to replace another shall only remain in office for the remaining term of office of
his predecessor. If the Meeting of Shareholders appoints several Statutory Auditors, they may act together or separately but they must draft a
joint report.

One  or  more  shareholder(s)  with  a  shareholding  of  at  least  5%  may  apply  to  the  courts  to  dismiss  one  or  more  of  the  Statutory  Auditors
appointed by the Meeting of Shareholders and request the appointment of one or more Statutory Auditors who will exercise their duties instead
of them. If their request is granted, the Statutory Auditors so appointed shall exercise their duties until the Statutory Auditors appointed by the
Meeting of Shareholders take up their posts.

The Statutory Auditors certify that the annual financial statements are in due form and give a true and fair view of the result of the operations of
the preceding financial year, and of the financial situation and assets and liabilities of the Company at the end of that financial year.

Their  permanent  role,  without  exercising  any  interference  with  management,  is  to  verify  the  company's  worth  and  financial  documents  and  to
ensure  that  its  accounting  is  in  compliance  with  the  rules  in  force.  They  also  verify  that  the  information  contained  in  Executive  Board
management report and in the documents provided to shareholders on the financial situation and annual accounts is fair and consistent with the
annual accounts. The Statutory Auditors ensure that equality among shareholders has been complied with.

The  Statutory  Auditors  may,  at  any  time  during  the  year,  carry  out  any  verification  or  supervision  they  consider  suitable  and  collect  any
information from third parties who have carried out assignments on behalf of the Company.

The Statutory Auditors prepare a report for the Meeting of Shareholders on the performance of their assignment. The Statutory Auditors attach a
report to the aforesaid report, presenting their comments on the report referred to in Article L. 225-68 paragraph 6 of the Commercial Code with
respect to internal supervision procedures relating to the preparation and treatment of accounting and financial information. They also prepare a
special report on the agreements referred to in Article 22 of these Articles of Association.

The Statutory Auditors are invited to attend the Executive Board meeting at which the financial statements for the preceding financial year are
approved, as well as to all Meeting of Shareholders. They may convene a Meeting of Shareholders under the conditions provided by statute.

There are three kinds of meeting, depending on the purpose of the proposed resolutions:

-    Ordinary Meeting of Shareholders,
-    Extraordinary Meeting of Shareholders,
-    Special Meeting of Shareholders of holders of a specific category of share.

ARTICLE 27 – Convening Meetings

Shareholders’  Meetings  are  convened  by  the  Executive  Board,  or  failing  that,  the  Supervisory  Board.  They  may  also  be  convened  by  the
Statutory Auditor(s) or by an agent appointed by the court in accordance with the procedures and conditions provided by statute.

During liquidation, Shareholders’ Meetings are convened by the liquidator.

Shareholders’  Meetings  are  held  at  the  registered  office,  in  any  other  place  of  the  same  department  indicated  in  the  convocation  notice  or  in
Paris.

Notice of the meeting is published in the Bulletin des Annonces Légales Obligatoires (BALO) (Mandatory Legal Notice Bulletin) at least thirty-five
days  prior  to  which  a  meeting  is  held.  In  addition  to  the  information  relating  to  the  Company,  it  also,  in  particular,  sets  out  the  agenda  of  the
Meeting and the draft text of the resolutions which will be proposed. Subject to particular legal requirements, requests for the inclusion of draft
resolutions on the agenda must be sent at the latest on the publication date of the notice of the meeting and up to twenty-five days prior to the
Shareholders’ Meeting; this deadline is twenty days from the publication date of the notice when the notice is published more than forty-five days
prior to the Shareholders’ Meeting.

Subject  to  particular  legal  requirements,  invitations  to  meetings  are  made  at  least  fifteen  days  prior  to  the  date  of  the  meeting  by  a  notice
published  in  both  the  legal  notice  journal  of  the  administrative  department  in  which  the  registered  office  is  located  and  in  the  Bulletin  des
Annonces Légales Obligatoires (BALO).

However,  holders  of  registered  shares  having  held  shares  for  at  least  one  month  as  at  the  date  of  the  last  of  the  published  notices  must  be
convened  individually  by  ordinary  letter  (or  by  registered  letter  if  they  have  requested  this  and  advanced  the  costs)  sent  to  their  last  known
address. Such notice may also be sent by electronic communication instead of such postal dispatch, to any shareholder who has so requested
beforehand by registered mail return receipt requested, in accordance with statutory and regulatory requirements, indicating his email address.
Such shareholder may send a request to the Company at any time by registered letter with acknowledgement of receipt for the aforementioned
method of telecommunication to be replaced by postal dispatch in the future.

Articles of Association.

If a Shareholders’ Meeting has not been able to deliberate due to the required quorum not being reached, a second Shareholders’ Meeting is
convened  with  at  least  ten  days’  advance  notice,  in  the  same  manner  as  the  first  meeting.  The  invitation  notice  or  letters  for  such  second
Shareholders’ Meeting state the date and agenda of the first meeting.

The agenda of a Meeting of Shareholders is decided by the person convening the meeting.

One or more shareholders representing at least the percentage of share capital determined by statute and acting pursuant to statutory conditions
and  within  statutory  time  periods,  may  request  items  or  draft  resolutions  to  be  included  on  the  agenda  of  the  Meeting  by  registered  mail  with
confirmation of receipt.

The Meeting of Shareholders cannot deliberate on an issue which has not been included on the agenda and such agenda cannot be modified on
second convocation of a Meeting of Shareholders. The Meeting of Shareholders may, however, in any circumstances, dismiss one or several
members of the Supervisory Board and effect their replacement.

ARTICLE 29 – Participation of Shareholders in Meeting of Shareholders

All shareholders are entitled to attend Shareholders’ Meetings and take part in deliberations:

(i)    either personally; or

(ii)    by giving a proxy to another shareholder or to his spouse; or

(iii)    by sending a blank proxy to the Company; or

(iv)    by voting by correspondence; or

(v)    by videoconference or by another means of telecommunication in accordance with the applicable statutory and regulatory provisions.

Participation in shareholders’ meetings in any manner is dependent on the registration or inscription of shares under the conditions and within
the deadlines set in the current regulations.

The final date for the return of correspondence voting forms is determined by the Executive Board and indicated in the notice of the meeting
published  in  the  Bulletin  des  Annonces  Légales  et  Obligatoires  (BALO).  This  date  cannot  be  prior  to  three  days  before  the  Shareholders’
Meetings.

If a shareholder is present at a Shareholders’ Meeting, any prior vote by correspondence will have no effect for the purposes of the aforesaid
Shareholders’ Meeting.

If both a proxy form and a correspondence voting form are returned, the proxy form will be taken into account, subject to the votes expressed in
the correspondence voting form.

ARTICLE 30 – Representation of Shareholders

I.    Any shareholder may be represented at Meeting of Shareholders by another shareholder, his spouse, his partner in a civil union or any other
natural or legal person of his choice through a proxy form sent to the shareholder by the Company:

successively with the same agenda.

ARTICLE 31 – Attendance Register

An attendance register is kept for each Meeting of Shareholders containing the information required by law.

The secretariat composed as such appoints a Secretary, who may be selected from outside of the shareholders.

22

TRANSLATION FOR INFORMATION PURPOSES

ARTICLE 32 – Quorum

in  Special  Meeting  of  Shareholders,  all  the  shares  of  the  relevant  category,  less  shares  stripped  of  their  voting  rights  pursuant  to  statutory
provisions.

The voting rights attached to shares are proportional to the portion of share capital which they represent. Each share entitling its holder to an
interest in the capital or to beneficial enjoyment carries one vote.

In the case of a vote by correspondence, only completed forms received by the Company at least three days prior the Meeting of Shareholders
shall be taken into account for the calculation of the quorum.

Forms which do not indicate which way to vote, or which indicate an abstention, are considered as negative votes.

ARTICLE 33 - Minutes

the members of the secretariat.

Copies  or  extracts  of  such  minutes  are  certified  either  by  the  Chairman  of  Vice-Chairman  of  the  Supervisory  Board  or  by  a  member  of  the

informed decision and have an informed judgement on the management and running of the Company.

The nature of these documents and the conditions in which they are sent or provided to shareholders are determined by regulations in force.

In exercising its right to receive documents, each shareholder or his agent may be assisted by a court-registered expert.

The exercise of the right to receive documents includes the right to make copies, except with respect to inventories.

B – Provisions Specific to
Ordinary Meetings of Shareholders

ARTICLE 35 – Ordinary Meeting of Shareholders

An Ordinary Meeting of Shareholders may make any decision other than one which directly or indirectly modifies the Articles of Association.

Ordinary Meetings of Shareholders are held at least once a year, within six months of the end of each financial year, to decide on the financial
statements for such financial year, subject to the extension of such period by an order of the President of the Commercial Court on petition from
the Executive Board.

They are called on an extraordinary basis every time it may be in interests of the Company to do so.

When  convened  for  the  first  time,  Ordinary  Meetings  of  Shareholders  can  only  make  valid  decisions  if  the  shareholders  that  are  present,
represented or voting by correspondence hold at least one fifth of the shares carrying the right to vote.

ARTICLE 36 – Extraordinary Meetings of Shareholders

An amendment to any provision of the Articles of Association and, in particular, the transformation of the Company into another form of company
may  only  be  decided  by  an  Extraordinary  Meeting  of  Shareholders. An  Extraordinary  Meeting  of  Shareholders  cannot,  however,  increase  the
undertakings of shareholders, subject to operations as a result of regrouping shares in a due and proper manner.

When  convened  for  the  first  time,  Extraordinary  Meeting  of  Shareholders  can  only  make  valid  decisions  if  the  shareholders  that  are  present,
represented or voting by correspondence hold at least a quarter of the shares carrying the right to vote, and when convened for the second time,

months from the date at which it was convened.

An Extraordinary Meeting of Shareholders makes decisions on the basis of a majority of two-thirds of the votes held by shareholders that are
present, represented or voting by correspondence or participating in the Meeting by video-conference or another method of telecommunication
in accordance with statutory and regulatory provisions.

By  statutory  derogation  from  the  preceding  provisions,  if  the  share  capital  is  increased  by  the  incorporation  of  profits,  reserves  or  issue
premiums,  the  Extraordinary  Meeting  of  Shareholders  may  make  decisions  at  the  quorum  and  majority  required  for  Ordinary  Meeting  of
Shareholders.

Moreover, where an Extraordinary Meeting of Shareholders is convened to deliberate on the approval of a contribution in kind or the grant of a
specific  benefit,  the  shares  of  the  contributing  party  or  beneficiary  shall  not  be  taken  into  account  in  calculating  the  majority. The  contributing
party or beneficiary cannot vote either in his own right or as an agent.

D - Provisions Specific to
Special Meetings of Holders of a Category of Shares

open only to holders of the relevant category of shares.

When  convened  for  the  first  time,  Special  Meetings  of  Shareholders  can  only  make  valid  decisions  if  the  shareholders  that  are  present,

accordance  with  statutory  or  regulatory  provisions,  hold  at  least  a  third  of  the  shares  carrying  the  right  to  vote,  and  when  convened  for  the

TITLE VI
FINANCIAL YEAR – ANNUAL FINANCIAL STATEMENTS
APPROPRIATION AND DISTRIBUTION OF PROFITS

ARTICLE 38 – Financial Year

The financial year begins on 1  January of each year and ends on 31  December.

st

st

ARTICLE 39 - Accounts

24

TRANSLATION FOR INFORMATION PURPOSES

Accounts of corporate operations are kept in due form in accordance with the law and usual business practice.

At the end of each financial year, the Executive Board shall draw up an inventory of the various assets and liabilities as at such date. It shall also
prepare the balance sheet describing the assets and liabilities, the income statement summarising the income and charges for the financial year
and the notes to the financial statements which complete and comment on the information provided in the balance sheet and income statement.

The  Executive  Board  shall  present  such  documents  to  the  Supervisory  Board  within  three  months  of  the  end  of  the  financial  year,  for  the
purposes of verification and supervision.
It shall prepare the management report on the situation of the Company during the preceding financial year.

All such documents shall be made available to the Statutory Auditors pursuant to the conditions specified by law.

ARTICLE 40 – Appropriation of Profits

The income statement which summarises the income and charges for the financial year, after depreciation and provisions have been deducted,
indicates the profit or loss of the financial year by setting forth the difference between these two amounts.

Five per cent. of the year's profit less previous losses, as the case may be, is allocated to the statutory reserve. Such allocation shall no longer
be necessary once the aforesaid reserve reaches one tenth of the share capital, but will become necessary again if for any reason whatsoever
the reserve falls below one tenth.

Distributable earnings consist of the net income of the financial year, less previous losses and amounts added to the reserve in accordance with
the law or the Articles of Association, plus retained earnings.

Moreover,  the  Meeting  of  Shareholders  may  decide  to  distribute  amounts  deducted  from  the  reserves  which  are  available  to  it,  expressly
indicating the reserves from which the withdrawals are to be made. However, dividend is paid out in priority from the distributable income of the
financial year.

Except in the case of a reduction in share capital, no distribution may be made to shareholders if shareholders’ equity is, or would become as a
result  of  such  distribution,  less  than  the  share  capital  plus  the  reserves  which  the  law  or  the  Articles  of  Incorporation  do  not  allow  to  be
distributed.

After  the  financial  statements  have  been  approved  and  the  existence  of  distributable  income  has  been  acknowledged,  the  Meeting  of
Shareholders shall determine the part to be allocated to shareholders as dividends, in proportion to the number of shares held by each.

However, after the allocation of the amounts required by law to the reserve, the Meeting of Shareholders may decide to allocate all or part of the
distributable income to a retained earnings account or to any general or special reserve account.

Any losses are deducted from profits from previous years until such losses are extinguished or they are carried over.

The Executive Board may decide to distribute interim dividends prior to the approval of the financial statements of the financial year, pursuant to
the conditions determined or authorised by law. The amount of such instalments cannot exceed the amount of earnings as defined by law.

ARTICLE 41 - Dividends

I.    The procedure for the payment of dividends is determined by the Meeting of Shareholders or, failing that, by the Executive Board. However,
payment must be made within a maximum of nine months after the end of the financial year, unless such period is extended by court decision.

Shareholders may not be required to reimburse any amount of dividends unless the distribution of dividends was in violation of law.

Claims for dividends made more than five years after they have been made available for payment shall time-barred.

25

TRANSLATION FOR INFORMATION PURPOSES

II.        The  Meeting  of  Shareholders  convened  to  approve  the  financial  statements  for  the  financial  year  may  grant  shareholders  the  option  of
dividends or interim dividends being paid in cash or in shares issued by Company, in whole or in part, in accordance with the conditions set out
or authorised by law.

TITLE VII
SHAREHOLDERS’ EQUITY FALLING BELOW ONE-HALF OF THE SHARE CAPITAL

ARTICLE 42 – Early Winding Up

If  the  Company's  shareholders'  equity  falls  below  one-half  of  the  share  capital  as  a  result  of  losses  recorded  in  the  financial  statements,  the
Executive Board must convene an Extraordinary Meeting of Shareholders within four months of the approval of the financial statements which
recorded such loss to decide whether to wind up the Company.

If  it  is  not  decided  to  wind  up  the  Company,  the  share  capital  must  be  reduced  by  an  amount  equal  to  the  recorded  losses,  within  a  period
determined by law, if shareholders’ equity has not reached at least one-half the amount of the share capital again within such period.

In either case, the decision of the Meeting of Shareholders shall be published according to regulatory conditions.

The  reduction  of  share  capital  to  an  amount  below  the  statutory  minimum  can  only  be  decided  subject  to  the  condition  precedent  of  a  share
capital increase to at least the statutory minimum.

If the provisions of one or more of the foregoing paragraphs are not complied with, any interested party may apply to the courts for the Company
to be wound up. This rule also applies if the shareholders are unable to deliberate validly.

However, the court may not wind up the Company if on the day of issue of a judgment on the substance of the matter the situation has been
rectified.

TITLE VIII
WINDING-UP – LIQUIDATION

ARTICLE 43 – Winding Up

The  Company  shall  be  wound  up  on  expiry  of  the  term  determined  in  the  Articles  of  association,  unless  this  is  extended,  or  pursuant  to  a
decision of an Extraordinary Meeting of Shareholders.

The Company may also be wound up at the request of any interested party, where the number of shareholders has dropped to under seven for
more than one year. In such case, the court may grant the Company a maximum of six months in which to rectify the situation. It cannot wind up
the Company if on the day it issued judgment on the substance of the matter, the situation has been rectified.

The Company shall be in liquidation as from the date on which it is wound up, for any reason whatsoever.

Winding up will cause the terms of office of members of the Executive Board to terminate. The Supervisory Board and Statutory Auditors shall
continue to operate.

Meeting of Shareholders shall retain the same powers as during the life of the company.

The  Meeting  of  Shareholders  which  decides  to  wind  up  the  company  shall  determine  the  procedure  for  liquidation  and  appoint  one  or  more
liquidators and determine their powers. The liquidator(s) shall exercise their duties in accordance with the law in force.

The Company shall continue to have legal personality for the purposes of and until the completion of its liquidation. However, its corporate name
should be followed by the words "Company in liquidation" as well as the name(s) of the liquidator(s) on any instruments or documents issued by
the Company to third parties.

26

TRANSLATION FOR INFORMATION PURPOSES

Shares remain negotiable until the completion of liquidation.

After liabilities have been cleared, the net proceeds of liquidation are applied to the full repayment of paid up non-depreciated shares.

Any surplus shall be distributed among the shareholders in proportion to the number of shares held by each of them.

TITLE IX
DISPUTES

ARTCLE 44 - Disputes

Any  dispute  which  may  arise  during  the  life  or  liquidation  of  the  Company,  either  between  shareholders  and  the  Company  or  between  the
shareholders  themselves,  concerning  corporate  matters,  shall  be  resolved  in  accordance  with  the  law  and  submitted  to  the  jurisdiction  of  the
competent courts at the registered office.

To this effect, in the case of a dispute, any shareholder is bound to designate an address for service of process within the area of jurisdiction of
the court of the Company's registered office, any writs or notifications shall be validly issued to that address.

If an address for service of process is not designated, writs or notifications shall be validly issued to the Public Prosecutor of the Court of First
Instance in the area of the registered office.

General

Description of Share capital

The following description of our share capital summarizes certain provisions of our bylaws. Such summaries do not purport to be complete and
are subject to, and are qualified in their entirety by reference to, all of the provisions of our bylaws, a copy of which has been filed as an exhibit
attached to Innate’s annual report on Form 20-F of which this exhibit forms a part.

As of December 31, 2024, our outstanding share capital consisted of a total of 83,830,336 ordinary shares with a nominal value of €0.05 per
share and 14,075 preferred shares (6,494 “2016” free preferred shares and 7,581 “2017” free preferred shares) with a nominal value of €0.05 per
share. As of December 31, 2024, we had the following equity warrants, redeemable share subscription warrants, and free shares and convertible
preferred shares outstanding:

•

•

•
•
•

•

•

•

167,460 ordinary shares issuable upon the exercise of share warrants (BSA) outstanding at a weighted average exercise price of € 7,84

per ordinary share;
1,045,722 ordinary shares issuable upon the exercise of redeemable share warrants (BSAAR) outstanding at an exercise price of € 7.20
per ordinary share;

787,220 ordinary shares issuable upon conversion of 6,494 free preferred shares (AGAP 2016);

618,760 ordinary shares issuable upon the vesting of 618,760 free shares (AGA);

100,000 ordinary shares issuable upon the exercise of stock options (Stock Options) outstanding at a weighted average exercise price of
€2.18 per ordinary share;

assuming all performance and presence conditions are met;

assuming all performance and presence conditions are met; and
2,287,900 ordinary shares issuable upon definitive acquisition of 2,287,900 free performance shares 2024 (AGA de Performance 2024),
assuming all performance and presence conditions are met.

Under French law, our bylaws set forth only our issued and outstanding share capital as of the date of the bylaws. Our fully diluted share capital
represents all issued and outstanding ordinary shares, as well as all potential ordinary shares which may be issued upon exercise of outstanding
equity  warrants  and  redeemable  share  subscription  warrants  and  following  the  vesting  of  free  shares,  as  approved  by  our  shareholders  and
granted by our Executive Board.

As of December 31, 2024, our share capital as set forth in our bylaws is €4,192,220.55. An increase of our share capital may only be approved
by an extraordinary meeting of shareholders or as delegated to the Executive Board by an extraordinary meeting of shareholders.

Rights, preferences and restrictions attaching to ordinary shares

Rights and Obligations Attached to Ordinary Shares (Articles 12 and 41 of the Bylaws)

Each of our ordinary shares gives the right to a share of the profits and assets in proportion to the amount of capital it represents. It also gives the
right to vote and be represented in the General Meeting of shareholders under the conditions set forth by the law and the bylaws.

If we are liquidated, any assets remaining after payment of the debts, liquidation expenses and all of the remaining obligations will first be used
to repay in full the par value of our ordinary shares. Any surplus will be distributed pro rata among shareholders in proportion to the number of
ordinary shares respectively held by them, taking into account, where applicable, of the rights attached to ordinary shares of different classes.

Shareholders are liable for corporate liabilities only up to the par value of the ordinary shares they hold; they are not liable to further capital
calls.

Shareholders’ rights may be modified as allowed by French law. Only the extraordinary shareholders’ meeting is authorized to amend any and all
provisions of our bylaws. It may not, however, increase shareholder commitments without the prior approval of each shareholder.

Voting Rights (Article 12 of the Bylaws)

The voting rights attached to the ordinary shares are in proportion to the amount of capital they represent and each share gives the right to one
vote. There is no double voting right attached to the ordinary shares. The ownership of a share implies, ipso facto, the acceptance of our bylaws
and any decision of our shareholders.

Under  French  law,  treasury  shares  or  ordinary  shares  held  by  entities  controlled  by  us  are  not  entitled  to  voting  rights  and  do  not  count  for
quorum purposes.

4

There  is  no  limitation  on  voting  rights  in  our  bylaws  nor  limit  the  right  of  non-residents  of  France  or  non-French  persons  to  own  or,  where
applicable, to vote our securities.

Under French law, the holders of warrants of the same class (i.e., warrants that were issued at the same time and with the same rights), including
founders’  warrants,  are  entitled  to  vote  as  a  separate  class  at  a  general  meeting  of  that  class  of  warrant  holders  under  certain  circumstances,
principally  in  connection  with  any  proposed  modification  of  the  terms  and  conditions  of  the  class  of  warrants  or  any  proposed  issuance  of
preferred shares or any modification of the rights of any outstanding class or series of preferred shares.

Dividends (Article 41 of the Bylaws)

We may only distribute dividends out of our distributable profits, plus any amounts held in our reserves that the shareholders decide to make
available for distribution, other than those reserves that are specifically required by law. The conditions for payment of dividends in cash shall be
set at the shareholders’ meeting or, as the case may be, by the Executive Board.

“Distributable  Profits”  consist  of  our  statutory  net  profit  in  each  fiscal  year,  calculated  in  accordance  with  accounting  standards  applicable  in
France, as increased or reduced by any profit or loss carried forward from prior years, less any contributions to the reserve accounts. Pursuant to
French law, we must allocate at least 5% of our statutory net profit for each year to our legal reserve fund before dividends may be paid with
respect to that year. Such allocation is compulsory until the amount in the legal reserve is equal to 10% of the aggregate par value of our issued
and outstanding share capital.

Dividends are distributed to shareholders pro rata according to their respective holdings of ordinary shares or preferred shares, as the case may
be. In the case of interim dividends, distributions are made to shareholders on the date set by our Executive Board during the meeting in which
the  distribution  of  interim  dividends  is  approved.  The  actual  dividend  payment  date  is  decided  by  the  shareholders  at  an  ordinary  general
shareholders’ meeting or by our Executive Board in the absence of such a decision by the shareholders. Shareholders that own ordinary shares on
the actual payment date are entitled to the dividend.

Pursuant to French law, dividends must be paid within a maximum of nine months after the close of the relevant fiscal year, unless extended by
court order. Dividends not claimed within five years after the payment date shall be deemed to expire and revert to the French state.

Shareholders may be granted an option to receive dividends in cash or in ordinary shares, in accordance with legal conditions.

Change in Share Capital (Article 7 of the Bylaws)

Any change to the capital or the rights attached to the ordinary shares is subject to legal provisions, as our bylaws do not set forth any particular
requirements.

5

Increase in Share Capital

Pursuant to French law, our share capital may be increased only with shareholders’ approval at an extraordinary general shareholders’ meeting
following the recommendation of our Executive Board. The shareholders may delegate to our Executive Board either the authority (délégation
de compétence) or the power (délégation de pouvoir) to carry out any increase in share capital.

Increases in our share capital may be effected by:

•
•
•
•

issuing additional shares;

increasing the nominal value of existing shares;

creating a new class of equity securities (preferred shares); and

exercising the rights attached to securities giving access to the share capital.

Increases in share capital by issuing additional securities may be effected through one or a combination of the following issuances:

•
•
•
•
•
•
•

in consideration for cash;

in consideration for assets contributed in kind;

through an exchange offer or merger;

by conversion of previously issued debt instruments;

by exercise of the rights attached to securities giving access to the share capital;

by capitalization of profits, reserves or share premium; and

subject to certain conditions, by way of offset against debt incurred by us.

Decisions to increase the share capital through the capitalization of reserves, profits and/or share premium require shareholders’ approval at an
extraordinary general shareholders’ meeting, acting under the quorum and majority requirements applicable to ordinary shareholders’ meetings.
Increases effected by an increase in the nominal value of shares require unanimous approval of the shareholders, unless effected by capitalization
of reserves, profits or share premium. All other capital increases require shareholders’ approval at an extraordinary general shareholders’ meeting
acting under the regular quorum and majority requirements for such meetings.

Reduction in Share Capital

Pursuant  to  French  law,  any  reduction  in  our  share  capital  requires  shareholders’  approval  at  an  extraordinary  general  shareholders’  meeting
following  the  recommendation  of  our  Executive  Board.  The  share  capital  may  be  reduced  either  by  decreasing  the  nominal  value  of  the
outstanding shares or by reducing the number of outstanding shares (including by the repurchase and cancellation of shares). Holders of each
class of shares must be treated equally unless each affected shareholder agrees otherwise, depending on the contemplated operations.

6

Preferential Subscription Rights

According  to  French  law,  if  we  issue  additional  securities  for  cash,  current  shareholders  will  have  preferential  subscription  rights  to  these
securities on a pro rata basis. Preferential subscription rights entitle the individual or entity that holds them to subscribe pro rata based on the
number of shares held by them to the issuance of any securities increasing, or that may result in an increase of, our share capital by means of a
cash payment or a set-off of cash debts. Pursuant to French law, the preferential subscription rights are transferable during a period equivalent to
the subscription period relating to a particular offering but starting two business days prior to the opening of the subscription period and ending
two business days prior to the closing of the subscription period.

The preferential subscription rights with respect to any particular offering may be waived at an extraordinary general meeting by a two-thirds
vote of our shareholders or individually by each shareholder.

Our  Executive  Board  and  our  independent  statutory  auditors  are  required  by  French  law  to  present  reports  to  the  shareholders’  meeting  that
specifically address any proposal to waive the preferential subscription rights.

Form, Holding and Transfer of Shares (Articles 9 and 10 of the Bylaws)

Form of Shares

The  ordinary  shares  are  nominative  or  bearer,  if  the  legislation  so  permits,  according  to  the  shareholder’s  choice.  The  Free  Preferred  Shares
(AGAP) are nominative.

Further,  in  accordance  with  applicable  laws,  we  may  request  at  any  time  from  the  central  depository  responsible  for  holding  our  Shares,  the
information referred to in Article L. 228-2 of the French Commercial Code. Thus, we are, in particular and at any time, entitled to request the
name and year of birth or, in the case of a legal entity, the name and the year of incorporation, nationality and address of holders of securities
conferring immediate or long-term voting rights at its shareholders’ meeting and the amount of securities owned by each of them and, where
applicable, the restrictions that the securities could be affected by.

Holding of Shares

In accordance with French law concerning the “dematerialization” of securities, the ownership rights of shareholders are represented by book
entries instead of share certificates. Shares issued are registered in individual accounts opened by us or any authorized intermediary, in the name
of each shareholder and kept according to the terms and conditions laid down by the legal and regulatory provisions.

7

Ownership of Shares by Non-French Persons

See  “Description  of  Share  Capital-Rights,  preferences  and  restrictions  attaching  to  ordinary  shares-Limitations  Affecting  Shareholders  of  a
French company.”

Assignment and Transfer of Shares

Shares  are  freely  negotiable,  subject  to  applicable  legal  and  regulatory  provisions.  French  law  notably  provides  for  standstill  obligations  and
prohibition of insider trading.

Repurchase and Redemption of Ordinary Shares

Under French law, we may acquire our own ordinary shares. Such acquisition may be challenged on the ground of market abuse regulations.
However, Market Abuse Regulation (EU) No. 596/2014 of April 16, 2014, as amended, and its related delegated regulations, or MAR, provides
for safe harbor exemptions when the acquisition is made (i) under a buy-back program to be authorized by the shareholders in accordance with
the  provisions  of  Article  L.  22-10-62  of  the  French  Commercial  Code  and  with  the  General  Regulation  of  the  French  Financial  Markets
Authority, or AMF and (ii) for the following purposes:

•

•
•

to decrease our share capital, provided that such a decision is not driven by losses and that a purchase offer is made to all shareholders on
a pro rata basis, with the approval of the shareholders at an extraordinary general meeting; in this case, the ordinary shares repurchased
must be cancelled within one month from their repurchase date;
to meet obligations arising from debt securities that are exchangeable into equity instruments; or

to meet our obligations arising from share option programs, or other allocations of ordinary shares, to our employees or to our managers

or  the  employees  or  managers  of  our  affiliate.  In  this  case  the  shares  repurchased  must  be  distributed  within  12  months  from  their
repurchase, after which they must be cancelled.

In addition, we benefit from a simple exemption when the acquisition is made under a liquidity contract complying with the General Regulation
of, and market practices accepted by, the AMF.
All  other  purposes,  and  especially  share  buy-backs  made  for  external  growth  operations  in  pursuance  of Article  L.  22-10-62  of  the  French
Commercial Code, while not forbidden, must be pursued in strict compliance of market manipulation and insider dealing rules.

Under MAR and in accordance with the General Regulation of the AMF, we shall report to the AMF, no later than by the end of the seventh daily
market session following the date of the execution of the transaction, all the transactions relating to the buy-back program. In addition, we shall
provide  to  the AMF,  on  a  monthly  basis,  and  to  the  public  on  a  biannual  basis,  a  summary  report  of  the  transactions  made  under  a  liquidity
contract.

In any case, no such repurchase of ordinary shares may result in us holding, directly or through a person acting on our behalf, more than (i) 10%
of our issued share capital, or (ii) 5% of our issued

8

share capital in case of repurchase of shares to be used in payment or in exchange in the context of a merger, division or transfer of assets.

Ordinary shares repurchased by us continue to be deemed “issued” under French law but are not entitled to dividends and/or voting rights so
long as we hold them directly or indirectly, and we may not exercise the preemptive rights attached to them.

Sinking Fund Provisions

Our bylaws do not provide for any sinking fund provisions.

Our Bylaws and French Corporate Law Contain Provisions that May Delay or Discourage a Takeover Attempt

Provisions contained in our bylaws and French corporate law could make it more difficult for a third-party to acquire us, even if doing so might
be beneficial to our shareholders. In addition, provisions of our bylaws impose various procedural and other requirements, which could make it
more difficult for shareholders to effect certain corporate actions. These provisions include the following:

•

•

•

•

under French law, the owner of 90% of the share capital or voting rights of a public company listed on a regulated market in a Member
State of the European Union or in a state party to the European Economic Area, or EEA, Agreement, including from the main French
stock exchange, has the right to force out minority shareholders following a tender offer made to all shareholders;

under  French  law,  a  non-resident  of  France  as  well  as  any  French  entity  controlled  by  non-residents  of  France  may  have  to  file  a
declaration for statistical purposes with the Bank of France (Banque de France) within 20 working days following the date of certain
direct  foreign  investments  in  us,  including  any  purchase  of  our  ADSs.  In  particular,  such  filings  are  required  in  connection  with
investments exceeding €15,000,000 that lead to the acquisition of at least 10% of our share capital or voting rights or cross such 10%
threshold.  See  “Description  of  Share  Capital-Rights,  preferences  and  restrictions  attaching  to  ordinary  shares-Limitations  Affecting
Shareholders of a French company;”
under French law, certain investments in a French company relating to certain strategic industries by individuals or entities not residents
in a Member State of the EU are subject to prior authorization of the Ministry of Economy. See “Description of Share Capital-Rights,
preferences and restrictions attaching to ordinary shares-Limitations Affecting Shareholders of a French company;’’
a merger (i.e., in a French law context, a share for share exchange following which our Company would be dissolved into the acquiring
entity  and  our  shareholders  would  become  shareholders  of  the  acquiring  entity)  of  our  Company  into  a  company  incorporated  in  the
European Union would require the approval of our Executive Board as well as a two-thirds majority of the votes cast by the shareholders
present, represented by proxy or voting by mail at the relevant meeting;

9

•

•
•

•

•
•

•

•

•

•

•

•

a  merger  of  our  Company  into  a  company  incorporated  outside  of  the  European  Union  would  require  100%  of  our  shareholders  to
approve it;
under French law, a cash merger is treated as a share purchase and would require the consent of each participating shareholder;

our shareholders may grant in the future our Executive Board broad authorizations to increase our share capital or to issue additional

ordinary shares or other securities (for example, warrants) to our shareholders, the public or qualified investors, including as a possible
defense following the launching of a tender offer for our ordinary shares;
our shareholders have preferential subscription rights on a pro rata basis on the issuance by us of any additional securities for cash or a

set-off  of  cash  debts,  which  rights  may  only  be  waived  by  the  extraordinary  general  meeting  (by  a  two-thirds  majority  vote)  of  our
shareholders or on an individual basis by each shareholder;
our Supervisory Board appoints the members of the Executive Board and shall fill any vacancy within two months;

our Supervisory Board has the right to appoint members of the Supervisory Board to fill a vacancy created by the resignation or death of
a  member  of  the  Supervisory  Board  for  the  remaining  duration  of  such  member’s  term  of  office,  and  subject  to  the  approval  by  the
shareholders  of  such  appointment  at  the  next  shareholders’  meeting,  which  prevents  shareholders  from  having  the  sole  right  to  fill
vacancies on our Supervisory Board;
our Executive Board can be convened by the chairman of the Executive Board or other members of the Executive Board delegated for
this purpose;

our Supervisory Board can be convened by the chairman or the vice-chairman of the Supervisory Board. A member of the Executive
Board or one-third of the members of the Supervisory Board may send a written request to the chairman to convene the Supervisory
Board. If the chairman does not convene the Supervisory Board 15 days following the receipt of such request, the authors of the request
may themselves convene the Supervisory Board;

adopted by two-thirds of the votes of our shareholders present, represented by a proxy or voting by mail at the meeting.

Shareholder Identification (Article 9 of the Bylaws)

Ordinary Shares may be registered or bearer ordinary shares, at the option of the shareholder, subject to the applicable legal requirements.

To  identify  the  holders  of  bearer  ordinary  shares,  we  are  authorized  to  ask  in  accordance  with  current  legal  and  regulatory  requirements,  the
central depositary that maintains the records of the issue of these ordinary shares, in exchange for a fee, for the holders’ name or business name,
year of birth or year of incorporation, address and nationality, e-mail address, number of securities held giving immediate or future access to the
capital and any restrictions to which the securities are subject.

Modification of the Bylaws (Article 36 of the Bylaws)

Our bylaws may only be amended by approval at an extraordinary shareholders’ meeting. Our bylaws may not, however, be amended to increase
shareholder  commitments  without  the  approval  of  each  shareholder.  Decisions  are  made  by  a  two-thirds  majority  of  the  votes  cast  by  the
shareholders present, represented by proxy, or voting by mail.

Crossing the Threshold Set in the Bylaws (Article 11 of the Bylaws)

Without prejudice to the legal or regulatory stipulations, any natural person or legal entity who goes above or below, directly or indirectly, acting
alone or in concert (de concert), a percentage of the share capital or voting rights equal to or higher than 1% or a multiple of this percentage,
must inform us of the total number of ordinary shares, voting rights and securities giving access to capital or voting rights that it, he or she owns
immediately or eventually, within five trading days of the date on which such ownership threshold is crossed.

If shareholders fail to comply with these obligations, shares or voting rights exceeding the fraction that should have been declared are deprived
of voting rights at General Meetings of Shareholders for any meeting that would be held until the expiry of a period of two years from the date of
regularization  of  the  notification  in  accordance  with  Article  L.  233-14  of  the  French  Commercial  Code,  if  the  failure  to  declare  has  been
determined and one or several shareholders holding at least 5% of the capital make a request thereof, as recorded in the minutes of the General
Meeting.

These requirements are without prejudice to the threshold crossing declarations provided for under French law in Articles L. 233-7, L. 233-9 and
L. 233-10 of the French Commercial Code, which impose a declaration to us and to the AMF upon crossing of the following thresholds in share
capital

11

or voting rights no later than the fourth trading day following the crossing: 5%, 10%, 15%, 20%, 25%, 30%, 33.33%, 50%, 66.66%, 90% and
95%.

This obligation also applies when crossing each of the above-mentioned thresholds in a downward direction.

In addition, any shareholder crossing, alone or acting in concert, the 10%, 15%, 20% or 25% thresholds shall file a declaration with the AMF
pursuant to which it shall expose its intention for the following six months, including notably whether it intends to continue acquiring shares of
the Company or to acquire control over the Company and its intended strategy for the Company. Further, and subject to certain exemptions, any
shareholder  crossing,  alone  or  acting  in  concert,  the  30%  threshold  shall  file  a  mandatory  public  tender  offer  with  the  AMF.  Also,  any
shareholder holding directly or indirectly a number between 30% and 50% of the capital or voting rights and who, in less than 12 consecutive
months, increases their holding of capital or voting rights by at least 1% of the Company’s capital or voting rights, shall file a mandatory public
tender offer.

Differences in Corporate Law

We are a société anonyme à directoire et conseil de surveillance, or S.A., incorporated under the laws of France. The laws applicable to
French  sociétés  anonymes  differ  from  laws  applicable  to  U.S.  corporations  and  their  shareholders.  Set  forth  below  is  a  summary  of  certain
material differences between the provisions of the French Commercial Code applicable to us and the Delaware General Corporation Law, the
law under which many public companies in the United States are incorporated, relating to shareholders’ rights and protections. This summary is
not intended to be a complete discussion of the respective rights. For a more complete discuss, please refer to the Delaware General Corporation
Law, French law (including, in particular the French Commercial Code) and our bylaws.

In  addition,  the  composition  of  the  Executive  Board
endeavors  to  seek  a  balanced  representation  of  women
and  men.  The  number  of  members  of  the  Executive
Board and of the Supervisory Board is fixed by or in the
manner provided in the bylaws. The number of members
of the Supervisory Board of each gender may not be less
than  40%  when  the  Company  is  listed  on  a  regulated
market  or  when  the  Company  meets  certain  criteria  of
turnover  and  number  of  employees,  if  not  listed  on  a
regulated  market.  As  an  exception,  for  a  supervisory
board  having  up  to  8  members,  the  difference  between
each gender may not exceed 2. Any appointment made in
violation  of  this  limit  that  is  not  remedied  will  be  null
and  void  as  well  as  the  deliberations  taken  by  the
Supervisory  Board  member  irregularly  appointed.  The
members  of  the  Supervisory  Board  are  appointed  at  the
shareholders’ general meetings.
Under  French

addition,  under  French  law,  members  of  a  supervisory
board  of  a  corporation  may  be  legal  entities  (with  the
exception of the chairman of the Supervisory Board), and
such  legal  entities  may  designate  an  individual  to
represent  them  and  to  act  on  their  behalf  at  meetings  of

Vacancies on the Executive
Board and on the
Supervisory Board

Annual General Meeting

Under French law, the members of the Executive Board
and  of  the  Supervisory  Board  may  be  removed  from
office,  with  or  without  cause  and  without  notice,  at  any
shareholders’  meeting,  by  a  simple  majority  vote  of  the
shareholders present and voting at the meeting in person
or  by  proxy.  In  addition,  the  members  of  the  Executive
Board  may  be  removed  by  the  Supervisory  Board  if
provided  in  the  bylaws.  Our  bylaws  provide  this
possibility.  If  the  removal  of  members  of  the  Executive
Board  is  decided  without  just  cause,  it  may  give  rise  to
damages
Under  French  law,  vacancies  on  the  Executive  Board
resulting from death or a resignation have to be filled by
the  Supervisory  Board  within  two  months,  unless  the
Supervisory  Board  decides  to  amend  the  number  of
Executive Board members. Vacancies on the Supervisory
Board resulting from death or a resignation, may be filled
temporarily  by 
the
Supervisory  Board  (provided 
the  number  of
members  remaining  in  office  is  at  least  three)  pending
ratification by the shareholders by the next shareholders’
meeting.
Under  French  law,  the  annual  general  meeting  of
shareholders shall be held at such place, on such date and
at such time as decided each year by the Executive Board
and  notified  to  the  shareholders  in  the  convening  notice
of the annual meeting, within six months after the close
of the relevant fiscal year unless such period is extended
by court order.

incorporation, stockholders may effect such removal only
for cause.

Under Delaware law, vacancies on a corporation’s board
of directors, including those caused by an increase in the
number  of  directors,  unless  otherwise  provided  in  the
certificate of incorporation, may be filled by stockholders
or by a majority of the remaining directors.

Under Delaware law, the annual meeting of stockholders
shall be held at such place, on such date and at such time
as may be provided by the certificate of incorporation or
by the bylaws, or by the board of directors if neither the
certificate  of  incorporation  or  the  bylaws  so  provide,

Under  Delaware  law,  unless  otherwise  provided  in  the
certificate  of  incorporation  or  bylaws,  written  notice  of
any  meeting  of  the  stockholders  must  be  given  to  each
stockholder  entitled  to  vote  at  the  meeting  not  less  than
10 nor more than 60 days before the date of the meeting
and  shall  specify  the  place,  date,  hour,  means  of  remote
communication, if any, by which stockholders and proxy
holders may be deemed to be present in person and vote,

Notice of General Meetings A  first  convening  notice  is  published  in  the  French
Bulletin of Mandatory Legal Notices (BALO) at least 35
days  prior  to  a  meeting  and  made  available  on  the
website  of  the  Company  at  least  21  days  prior  to  the
meeting. Subject to special legal provisions, the meeting
notice is sent out at least 15 days prior to the date of the
meeting,  by  means  of  a  notice  inserted  both  in  a  legal
announcement bulletin (journal d’annonces légales) of
the  registered  office  department  and  in  the  BALO.
Further,  the  holders  of  registered  shares  for  at  least  a
month  at  the  time  of  the  latest  of  the  insertions  of  the
notice  of  meeting  shall  be  summoned  individually,  by
regular letter (or by registered letter if they request it and
include an advance of expenses) sent to their last known
address. This  notice  to  registered  shareholders  may  also
be 
of
telecommunication,  in  lieu  of  any  such  mailing,  to  any
shareholder  requesting  it  beforehand  by  registered  letter
with acknowledgment of receipt in accordance with legal
and  regulatory  requirements,  specifying  his  e-mail
address.  When 
the  shareholders’  meeting  cannot
deliberate  due  to  lack  of  required  quorum,  the  second
meeting  must  be  called  at  least  ten  calendar  days  in
advance in the same manner as used for the first notice.

and participate in the discussions (i) personally, or (ii) by
granting  proxy  to  another  shareholder,  his/her  spouse,
his/her partner with whom he/she has entered into a civil
union or to any natural or legal person of his/her choice;
or  (iii)  by  sending  a  proxy  to  the  Company  without

Preemptive Rights

Sources of Dividends

Under  French  law,  in  case  of  issuance  of  additional
ordinary  shares  or  other  securities  for  cash  or  set-off
against  cash  debts,  the  existing  shareholders  have
preferential  subscription  rights  to  these  securities  on  a
pro  rata  basis  unless  such  rights  are  waived  by  a  two-
thirds  majority  of  the  votes  cast  by  the  shareholders
present  at 
the  extraordinary  meeting  deciding  or
authorizing  the  capital  increase,  voting  in  person  or
represented  by  proxy  or  voting  by  mail.  In  case  such
rights  are  not  waived  by  the  extraordinary  general
individually  either
meeting,  each  shareholder  may 
exercise,  assign  or  not  exercise 
its  preferential
subscription  rights.  Preferential  subscription  rights  may
only  be  exercised  during  the  subscription  period.  In
accordance with French law, the exercise period shall not
be  less  than  five  trading  days.  Preferential  subscription
rights  are  transferable  during  a  period  equivalent  to  the
subscription  period  but  starting  two  business  days  prior
to the opening of the subscription period and ending two
business  days  prior  to  the  closing  of  the  subscription
period.
Under  French  law,  dividends  may  only  be  paid  by  a
French  société  anonyme  out  of  “distributable  profits,”
plus  any  distributable 
reserves  and  “distributable
premium” that the shareholders decide to make available
for  distribution,  other  than  those  reserves  that  are
specifically  required  by  law.  “Distributable  profits”
consist  of  the  unconsolidated  net  profits  of  the  relevant
corporation for each fiscal year, as increased or reduced
by any profit or loss carried forward from prior years.
“Distributable  premium”  refers  to  the  contribution  paid
by  the  shareholders  in  addition  to  the  par  value  of  their

Under  Delaware  law,  unless  otherwise  provided  in  a
corporation’s  certificate  of  incorporation,  a  stockholder
does not, by operation of law, possess preemptive rights
to  subscribe  to  additional  issuances  of  the  corporation’s
stock.

Under Delaware law, subject to any restrictions under a
corporation’s certificate of incorporation, dividends may
be  paid  by  a  Delaware  corporation  either  out  of  (1)
surplus  as  defined  in  and  computed  in  accordance  with
Delaware law or (2) in case there is no such surplus, out
of its net profits for the fiscal year in which the dividend
is declared and/or the preceding fiscal year, except when
the capital is diminished by depreciation in the value of
its property, or by losses, or otherwise, to an amount less
than  the  aggregate  amount  of  capital  represented  by
issued and outstanding stock having a preference on the
distribution of assets.

Repurchase of Shares

Under  French  law,  a  corporation  may  acquire  its  own
ordinary  shares.  Such  acquisition  may  be  challenged  on
the ground of market abuse regulations. However, MAR
provides for safe harbor exemptions when the acquisition
is made for the following purposes:

Under  Delaware  law,  a  corporation  may  generally

employees  or  managers  of  its  affiliate.  In  this
case  the  shares  repurchased  must  be  distributed
within  12  months  from  their  repurchase,  after
which they must be cancelled.

A simple exemption is provided when the acquisition is
made  under  a  liquidity  contract  in  the  context  of  a  buy-
back  program  to  be  authorized  by  the  shareholders  in
accordance with the provisions of Article L. 22-10-62 of
the French Commercial Code and in accordance with the
General Regulation of the AMF.
All other purposes, and especially share buy-backs made
for external growth operations in pursuance of Article L.
22-10-62  of  the  French  Commercial  Code,  while  not
forbidden,  must  be  pursued  in  strict  compliance  of
market manipulation and insider dealing rules. Under the
MAR and in accordance with the General Regulation of
the AMF, a corporation shall report to the AMF, no later
than  by  the  end  of  the  seventh  daily  market  session
following the date of the execution of the transaction, all
the  transactions  relating  to  the  buy-back  program.  By
exception,  a  corporation  shall  provide  to  the AMF,  on  a
monthly  basis,  and  to  the  public  on  a  biannual  basis,  a
summary  report  of  the  transactions  made  under  a
liquidity contract. No such repurchase of ordinary shares
may result in the Company holding, directly or through a
person acting on its behalf, more than 10% of its issued
share capital.

19

Under  Delaware  law,  a  corporation’s  certificate  of
incorporation  may  include  a  provision  eliminating  or
limiting  the  personal  liability  of  a  director  or  officer  to
the corporation or its stockholders for monetary damages
arising  from  a  breach  of  fiduciary  duty  as  a  director  or
officer. However, no provision can eliminate the liability
of:

•

•

•

•

•

a  director  or  officer  for  any  breach  of  the
director’s  or  officer’s  duty  of  loyalty  to  the
corporation or its stockholders;
a  director  or  officer  for  acts  or  omissions  not  in
good faith or that involve intentional misconduct
or a knowing violation of law;
a director for intentional or negligent payment of
unlawful  dividends  or  stock  purchases  or
redemptions;
a  director  or  officer  for  any  transaction  from
which the director or officer derives an improper
personal benefit; or
an officer in any action by or in the right of the
corporation.

Delaware  law  provides  that,  unless  otherwise  provided
in  the  certificate  of  incorporation,  each  stockholder  is
entitled  to  one  vote  for  each  share  of  capital  stock  held
by such stockholder.

company,  approval  of  all  shareholders  of  the
corporation  (by  exception,  the  extraordinary
general  meeting  of  the  acquiring  company  may
delegate  to  the  Executive  Board  authority  to
decide  a  merger-absorption  or  to  determine  the
terms and conditions of the merger plan).

21

Generally, under Delaware law, unless the certificate of
incorporation provides for the vote of a larger portion of
the  stock  or  under  other  certain  circumstances,
completion  of  a  merger,  consolidation,  sale,  lease  or
exchange  of  all  or  substantially  all  of  a  corporation’s
assets or dissolution requires:

•
•

 the approval of the board of directors; and
the   approval  by  the  vote  of  the  holders  of  a
majority  of  the  outstanding  stock  or,  if  the
certificate  of  incorporation  provides  for  more  or
less  than  one  vote  per  share,  a  majority  of  the
votes  of  the  outstanding  stock  of  a  corporation
entitled to vote on the matter.

Dissent or Dissenters’
Appraisal Rights

French  law  does  not  provide  for  any  such  right  but
provides  that  a  merger  is  subject,  depending  on  the
circumstances  of  the  merger,  to  either  the  shareholders’
approval  by  a  two-thirds  majority  vote,  or  unanimous
decisions of the shareholders, as stated above.

Under Delaware law, a holder of shares of any class or
series has the right, in specified circumstances, to dissent
from a merger or consolidation by demanding payment in
cash for the stockholder’s shares equal to the fair value of
those  shares,  as  determined  by  the  Delaware  Chancery
Court in an action timely brought by the corporation or a
dissenting stockholder. Unless otherwise provided in the
certificate  of  incorporation,  Delaware  law  grants  these
the  case  of  mergers  or
appraisal  rights  only 
consolidations and not in the case of a sale or transfer of
assets or a purchase of assets for stock.
Further,  no  appraisal  rights  are  available  for  shares  of
any  class  or  series  that  is  listed  on  a  national  securities
exchange  or  held  of  record  by  more  than  2,000
stockholders,  unless  the  agreement  of  a  merger  or
consolidation  requires  the  holders  to  accept  for  their
shares anything other than:

•

shares of stock of the surviving corporation;
shares  of  stock  of  another  corporation  that  are
either listed on a national securities exchange or
held of record by more than 2,000 stockholders;
cash  in  lieu  of  fractional  shares  of  the  stock
described in the two preceding bullet points; or
any combination of the above.

In addition, appraisal rights are not available to holders
of  shares  of  the  surviving  corporation  in  specified
mergers  that  do  not  require  the  vote  of  the  stockholders
of the surviving corporation.

forth  the  standard  of  conduct  of  a  member  of  the
Executive  Board  and  of 
the  Supervisory  Board.
However,  members  of  the  Executive  Board  and  of  the
Supervisory  Board  have  a  duty  of  loyalty,  a  duty  to  act
without  self-interest,  on  a  well  informed  basis  and  they
cannot  make  any  decision  against  a  corporation’s
corporate interest (intérêt social). In addition, members
of the Executive Board shall take into account social and
environmental  issues  arising  out  of  the  Company’s
activity.
French  law  provides  that  a  shareholder,  or  a  group  of
to  seek
shareholders,  may 
indemnification from the Executive Board (but not from
the  Supervisory  Board)  of  a  corporation 
the
corporation’s interest if it fails to bring such legal action
itself. If so, any damages awarded by the court are paid
to  the  corporation  and  any  legal  fees  relating  to  such
action are borne by the relevant shareholder or the group
of shareholders.
The  plaintiff  must  remain  a  shareholder  through  the
duration of the legal action.
There is no other case where shareholders may initiate a
derivative action to enforce a right of a corporation.
A  shareholder  may  alternatively  or  cumulatively  bring
individual  legal  action  against  the  members  of  the
Executive  Board  only,  provided  he  has  suffered  distinct
damages  from  those  suffered  by  the  corporation.  In  this
case,  any  damages  awarded  by  the  court  are  paid  to  the
relevant shareholder.

Delaware  law  does  not  contain  specific  provisions
setting  forth  the  standard  of  conduct  of  a  director.  The
scope  of  the  fiduciary  duties  of  directors  is  generally
determined  by  the  courts  of  the  State  of  Delaware.  In
general, directors have a duty to act without self-interest,
on  a  well-informed  basis  and 
they
reasonably  believe  to  be  in  the  best  interest  of  the
stockholders.

in  a  manner 

Under  Delaware  law,  a  stockholder  may  initiate  a
derivative action to enforce a right of a corporation if the
corporation fails to enforce the right itself. The complaint
must:
•

state  that  the  plaintiff  was  a  stockholder  at  the
time  of  the  transaction  of  which  the  plaintiff
complains or that the plaintiff’s shares thereafter
devolved  on  the  plaintiff  by  operation  of  law;
and allege with particularity the efforts made by
the  plaintiff  to  obtain  the  action  the  plaintiff
desires from the directors and the reasons for the
plaintiff’s failure to obtain the action; or
state the reasons for not making the effort.
Additionally,  the  plaintiff  must  remain  a  stockholder
through  the  duration  of  the  derivative  suit.  The  action
will  not  be  dismissed  or  compromised  without  the
approval of the Delaware Court of Chancery.

Amendment of Certificate
of Incorporation

Under French law, corporations are not required to file a
certificate  of  incorporation  with  the  French  Registry  of
Commerce  and  Companies  (registre  du  commerce  et
des  sociétés)  and  only  have  bylaws  (statuts)  as
organizational documents.

Amendment of Bylaws

amendments 

Under  French  law,  only  the  extraordinary  shareholders’
meeting is authorized to adopt or amend the bylaws. The
Supervisory Board can amend the bylaws to comply with
mandatory legal provisions, subject to the ratification of
extraordinary
such 
shareholders’  meeting.  The  Supervisory  Board 
is
authorized to amend the bylaws as a result of a decision
to  relocate  the  Company’s  registered  office  in  France,
subject to ratification by the next ordinary shareholders’
meeting.

next 

the 

by 

Under  Delaware  law,  generally  a  corporation  may
amend its certificate of incorporation if:

•

•

its  board  of  directors  has  adopted  a  resolution
the  amendment  proposed  and
setting  forth 
declared its advisability; and
the  amendment  is  adopted  by  the  affirmative
votes of a majority (or greater percentage as may
be  specified  by  the  corporation)  of  the  voting
power  of  the  outstanding  shares  entitled  to  vote
on  the  amendment  and  a  majority  (or  greater
the
percentage  as  may  be  specified  by 
corporation)  of 
the
the  voting  power  of 
outstanding  shares  of  each  class  or  series  of
stock,  if  any,  entitled  to  vote  on  the  amendment
as a class or series.

Under  Delaware  law,  the  stockholders  entitled  to  vote
have  the  power  to  adopt,  amend  or  repeal  bylaws.  A
corporation  may  also  confer, 
its  certificate  of
incorporation, that power upon the board of directors.

Limitations affecting shareholders of a French company

Ownership of ADSs or Shares by Non-French Residents

Neither  the  French  Commercial  Code  nor  our  bylaws  presently  impose  any  restrictions  on  the  right  of  non-French  residents  or  non-French
shareholders to own and vote shares.

However,  non-French  residents  must  file  a  declaration  for  statistical  purposes  with  the  Bank  of  France  (Banque  de  France)  within  twenty
business days following the date of certain direct foreign investments in us, including any purchase of our ADSs. In particular such filings are
required in connection with investments exceeding €15,000,000 that lead to the acquisition of at least 10% of the share capital or voting rights or
cross such 10% threshold (Articles R. 152-1 et seq. of the French

24

Monetary and Financial Code). Violation of this filing requirement may be sanctioned by five years’ imprisonment and a fine up to twice the
amount of the relevant investment. This amount may be increased fivefold if the violation is made by a legal entity.

Moreover,  the  following  types  of  investments  are  subject  to  the  prior  authorization  of  the  French  Minister  of  Economy,  pursuant  to Articles
L.151-1 and seq. and R. 151-1 and seq. of the French Monetary and Financial Code, as amended by the decree (décret) No. 2023-1293 dated
December 28, 2023 and the order (arrêté) dated December 28, 2023 pursuant to the French foreign investment regime, which authorization, if
granted, may be subject to certain undertakings:

•

•

•

by  (a)  any  non-French  citizen,  (b)  any  French  citizen  not  residing  in  France,  within  the  meaning  of Article  4  B  of  the  French  Code
général des impôts, (c) any non-French entity or (d) any French entity controlled by one of the aforementioned individuals or entities;
consisting  of  the  (a)  acquisition  of  control,  within  the  meaning  of  Article  L.  233-3  of  the  French  Commercial  Code,  of  an  entity
incorporated under French law or an establishment registered in France, (b) the acquisition of all or part of a line of business of an entity
incorporated under French law, or (c) crossing, directly or indirectly, alone or in concert, the threshold of 25% of the voting rights of an
entity incorporated under French law, or (d) crossing, directly or indirectly, alone or in concert, the threshold of 10% of the voting rights
of a company incorporated under French law whose shares are admitted to trading on a regulated market; and
developing activities in certain strategic industries related to: (a) activities likely to prejudice national defense interests, participating in
the exercise of official authority or likely to prejudice public order and public security (including activities related to weapons, dual-use
goods and technologies, IT systems, cryptology, data capturing devices, gambling, toxic agents or data storage), (b) activities relating to
essential infrastructure, goods or services (including energy, water, transportation, space, telecom, public health, farm products, media or
critical  raw  materials),  (c)  research  and  development  activities  related  to  critical  technologies  (including  cybersecurity,  artificial
intelligence,  robotics,  additive  manufacturing,  semiconductors,  quantum  technologies,  energy  storage,  biotechnology,  technologies
involved  in  low-carbon  energy  production  or  photonics)  or  dual-use  goods  and  technologies  (Articles  R.  151-1 et seq.  of  the  French
Monetary and Financial Code).

The abovementioned (ii)(c) and (d) do not apply either to a natural person who is a national of a Member State of the European Union or of a
State  party  to  the  Agreement  on  the  European  Economic  Area  which  has  concluded  an  administrative  assistance  agreement  with  France  to
combat fraud and tax evasion and who is domiciled in one of these States, or to an entity in which all the members of the control chain, within
the meaning of II of Article R. 151-1 of the same Code, are governed by the law of one of these States or are nationals of and domiciled in one of
these States.

We are subject to this regulation. As a result, investors in our ordinary shares or ADSs will have to request the prior authorization of the French
Minister of Economy before acquiring our ordinary shares or ADSs if: (i) they are (a) a non-French citizen, (b) a French citizen not residing in
France, within the meaning of Article 4 B of the FTC, (c) a non-French entity or (d) a French entity controlled by one of the aforementioned
individuals or entities; and (ii) such investor (a) acquires control of us, (b) acquires all or part of one of our business lines or (c) is a non-EU or
non-EEA investors crossing,

25

directly or indirectly, alone or in concert, both 25% and 10% thresholds of voting rights of our share capital.

This  request  for  prior  authorization  must  be  filed  with  the  French  Minister  of  Economy,  which  has  30  business  days  from  receipt  of  the
completed  file  to  provide  a  first  decision  which  may  (i)  indicate  that  the  investment  is  not  covered  by  the  activities  subject  to  the  prior
authorization  of  the  French  Minister  of  Economy,  (ii)  unconditionally  authorize  the  investment  or  (iii)  indicate  that  further  examination  is
required. In the latter case, the French Minister of Economy must make a second decision within 45 business days from its first decision. In case
of lack of response from the French Minister of Economy within the above mentioned timeframe, the authorization will be deemed refused. If
the authorization is granted, it may be subject to the signature of a letter of undertaking aimed at protecting French national interests.

A  fast-track  procedure  shall  apply  for  any  non-EU  investor  exceeding  this  10%  threshold  who  will  have  to  notify  the  French  Minister  of
Economy who will then have 10 business days to decide whether or not the transaction should be subject to further examination.

If  an  investment  requiring  the  prior  authorization  of  the  French  Minister  of  Economy  is  completed  without  such  authorization  having  been
granted,  the  French  Minister  of  Economy  might  direct  the  relevant  investor  to  (i)  submit  a  request  for  authorization,  (ii)  have  the  previous
situation restored at its own expense, or (iii) amend the investment.

In the absence of such authorization, the relevant investment shall be deemed null and void.

The relevant investor might also be found criminally liable and might be sanctioned with a fine which cannot exceed the greater of: (i) twice the
amount of the relevant investment, (ii) 10% of the annual turnover before tax of the target company and (iii) € 5 million (for a company) or € 1
million (for an individual).

Failure to comply with such measures could therefore result in significant consequences on the applicable investor. Such measures could also
delay or discourage a takeover attempt, and we cannot predict whether these measures will result in a lower or more volatile market price of our
ADSs or ordinary shares.

Foreign Exchange Controls

Under current French foreign exchange regulations there are no restrictions on the amount of cash transfers that may be made to residents of
foreign countries (subject to the absence of any specific decision taken by the government otherwise). Laws and regulations concerning foreign
exchange  controls  do,  however,  require  that  all  payments  or  transfers  of  funds  made  by  a  French  resident  to  a  non-resident  such  as  dividend
payments  be  handled  by  an  accredited  intermediary.  All  registered  banks  and  substantially  all  credit  institutions  in  France  are  accredited
intermediaries. For completeness, there is a reporting obligation to custom officer for transfer of cash in banknotes and coins of EUR 10,000 or
more carried in, or out of, the European Union.

Availability of Preferential Subscription Rights

Our shareholders will have the preferential subscription rights described under “Description of Share Capital-Rights, preferences and restrictions
attaching to ordinary shares-Changes in Share Capital-Preferential Subscription Rights.” Under French law, shareholders have preferential rights
to  subscribe  for  cash  issues  of  new  shares  or  other  securities  giving  rights  to  acquire  additional  shares  on  a  pro  rata  basis.  Holders  of  our
securities in the United States (which may be represented by ADSs) will not be able to exercise preferential subscription rights for their securities
unless a registration statement under the Securities Act is effective with respect to such rights or an exemption from the registration requirements
imposed by the Securities Act is available. We may, from time to time, issue new shares or other securities giving rights to acquire additional
shares (such as warrants) at a time when no registration statement is in effect and no Securities Act exemption is available. If so, holders of our
securities in the United States will be unable to exercise any preferential subscription rights and their interests will be diluted. We are under no
obligation to file any registration statement in connection with any issuance of new shares or other securities. We intend to evaluate at the time of
any rights offering the costs and potential liabilities associated with registering the rights, as well as the indirect benefits to us of enabling the
exercise by holders of shares in the United States and ADS holders of the subscription rights, and any other factors we consider appropriate at the
time, and then to make a decision as to whether to register the rights. We cannot assure you that we will file a registration statement.

For holders of our ordinary shares represented by ADSs, the depositary may make these rights or other distributions available to ADS holders. If
the depositary does not make the rights available to ADS holders and determines that it is impractical to sell the rights, it may allow these rights
to lapse. In that case, ADS holders will receive no value for them. The section of this exhibit titled “Description of Securities Other than Equity
Securities-American Depositary Shares-Dividends and Other Distributions” explains in detail the depositary’s responsibility in connection with a
rights offering. See also “Risk Factors—Your right as a holder of ADSs to participate in any future preferential subscription rights offering or to
elect to receive dividends in shares may be limited, which may cause dilution to your holdings.” in our most recent Annual Report on Form 20-F.

American Depositary Shares.
Citibank, N.A. acts as the depositary for the American Depositary Shares related to our ordinary shares. Citibank, N.A.’s depositary offices are
located  at  388  Greenwich  Street,  New York,  New York  10013. American  Depositary  Shares  are  frequently  referred  to  as ADSs  and  represent
ownership interests in securities that are on deposit with the depositary. ADSs may be evidenced by certificates that are commonly known as
American Depositary Receipts, or ADRs. The depositary typically appoints a custodian to safekeep the securities on deposit. In this case, the
custodian is Citibank Europe plc, located at 1 North Wall Quay, Dublin 1, Ireland.

27

We  have  appointed  Citibank,  N.A.  as  depositary  pursuant  to  the  deposit  agreement. A  copy  of  the  deposit  agreement  is  on  file  with  the  SEC
under cover of a Registration Statement on Form F-6. You may obtain a copy of the deposit agreement from the SEC’s website (www.sec.gov).
Please refer to Registration Number 333-234063 when retrieving such copy.

Each ADS represents the right to receive, and to exercise the beneficial ownership interests in, one ordinary share that is on deposit with the
depositary  bank  and/or  custodian. An ADS  also  represents  the  right  to  receive,  and  to  exercise  the  beneficial  interests  in,  any  other  property
received by the depositary bank or the custodian on behalf of the owner of the ADS but that has not been distributed to the owners of ADSs
because of legal restrictions or practical considerations. The Company and the depositary bank may agree to change the ADS-to-Share ratio by
amending the deposit agreement. This amendment may give rise to, or change, the depositary fees payable by ADS owners. The custodian, the
depositary bank and their respective nominees will hold all deposited property for the benefit of the holders and beneficial owners of such ADSs.
The deposited property does not constitute the proprietary assets of the depositary bank, the custodian or their nominees. Beneficial ownership in
the deposited property will under the terms of the deposit agreement be vested in the beneficial owners of the ADSs. The depositary bank, the
custodian and their respective nominees are the record holders of the deposited property represented by the ADSs for the benefit of the holders
and beneficial owners of the corresponding ADSs. A beneficial owner of ADSs may or may not be the holder of ADSs. Beneficial owners of
ADSs  are  able  to  receive,  and  to  exercise  beneficial  ownership  interests  in,  the  deposited  property  only  through  the  registered  holders  of  the
ADSs, the registered holders of the ADSs (on behalf of the applicable ADS owners) only through the depositary bank, and the depositary bank
(on behalf of the owners of the corresponding ADSs) directly, or indirectly, through the custodian or their respective nominees, in each case upon
the terms of the deposit agreement.

If you are or become an owner of ADSs, you are or will become a party to the deposit agreement and therefore are or will be bound to its terms
and to the terms of any ADR that represents your ADSs. The deposit agreement and the ADR specify the rights and obligations as well as your
rights and obligations as owner of ADSs and those of the depositary bank. As an ADS holder you appoint the depositary bank to act on your
behalf in certain circumstances. The deposit agreement and the ADRs are governed by New York law. However, the obligations to the holders of
ordinary shares will continue to be governed by the laws of France, which may be different from the laws in the United States.

In  addition,  applicable  laws  and  regulations  may  require  you  to  satisfy  reporting  requirements  and  obtain  regulatory  approvals  in  certain
circumstances. You are solely responsible for complying with such reporting requirements and obtaining such approvals. Neither the depositary
bank, the custodian, Innate or any of their or the respective agents or affiliates shall be required to take any actions whatsoever on your behalf to
satisfy such reporting requirements or obtain such regulatory approvals under applicable laws and regulations.

As  an  owner  of ADSs,  we  will  not  treat  you  as  one  of  our  shareholders  and  you  will  not  have  direct  shareholder  rights.  French  law  governs
shareholder rights. The depositary bank will hold on your behalf the shareholder rights attached to the ordinary shares underlying your ADSs. As
an owner of ADSs you will be able to exercise the shareholders rights for the ordinary shares represented by your

28

ADSs through the depositary bank only to the extent contemplated in the deposit agreement. To exercise any shareholder rights not contemplated
in the deposit agreement you will, as an ADS owner, need to arrange for the cancellation of your ADSs and become a direct shareholder.

The  manner  in  which  you  own  the ADSs  (e.g.,  in  a  brokerage  account  vs.  as  registered  holder,  or  as  holder  of  certificated  vs.  uncertificated
ADSs) may affect your rights and obligations, and the manner in which, and extent to which, the depositary bank’s services are made available
to you. As an owner of ADSs, you may hold your ADSs either by means of an ADR registered in your name, through a brokerage or safekeeping
account, or through an account established by the depositary bank in your name reflecting the registration of uncertificated ADSs directly on the
books of the depositary bank (commonly referred to as the “direct registration system” or “DRS”). The direct registration system reflects the
uncertificated (book-entry) registration of ownership of ADSs by the depositary bank. Under the direct registration system, ownership of ADSs is
evidenced by periodic statements issued by the depositary bank to the holders of the ADSs. The direct registration system includes automated
transfers between the depositary bank and The Depository Trust Company (“DTC”), the central book-entry clearing and settlement system for
equity securities in the United States. If you decide to hold your ADSs through your brokerage or safekeeping account, you must rely on the
procedures of your broker or bank to assert your rights as ADS owner. Banks and brokers typically hold securities such as the ADSs through
clearing and settlement systems such as DTC. The procedures of such clearing and settlement systems may limit your ability to exercise your
rights as an owner of ADSs. Please consult with your broker or bank if you have any questions concerning these limitations and procedures. All
ADSs held through DTC will be registered in the name of a nominee of DTC. This summary description assumes you have opted to own the
ADSs  directly  by  means  of  an ADS  registered  in  your  name  and,  as  such,  we  will  refer  to  you  as  the  “holder.” When  we  refer  to  “you,”  we
assume the reader owns ADSs and will own ADSs at the relevant time.

The registration of the ordinary shares in the name of the depositary bank or the custodian shall, to the maximum extent permitted by applicable
law, vest in the depositary bank or the custodian the record ownership in the applicable ordinary shares with the beneficial ownership rights and
interests  in  such  ordinary  shares  being  at  all  times  vested  with  the  beneficial  owners  of  the  ADSs  representing  the  ordinary  shares.  The
depositary bank or the custodian shall at all times be entitled to exercise the beneficial ownership rights in all deposited property, in each case
only on behalf of the holders and beneficial owners of the ADSs representing the deposited property.

Dividends and Distributions

As  a  holder  of ADSs,  you  generally  have  the  right  to  receive  the  distributions  we  make  on  the  securities  deposited  with  the  custodian. Your
receipt  of  these  distributions  may  be  limited,  however,  by  practical  considerations  and  legal  limitations.  Holders  of ADSs  will  receive  such
distributions under the terms of the deposit agreement in proportion to the number of ADSs held as of the specified record date, after deduction
of the applicable fees, taxes and expenses.

Distributions of Cash

29

Whenever  we  make  a  cash  distribution  for  the  securities  on  deposit  with  the  custodian,  we  will  deposit  the  funds  with  the  custodian.  Upon
receipt of confirmation of the deposit of the requisite funds, the depositary bank will arrange for the funds received in a currency other than U.S.
dollars to be converted into U.S. dollars and for the distribution of the U.S. dollars to the holders, subject to French laws and regulations.

The conversion into U.S. dollars will take place only if practicable and if the U.S. dollars are transferable to the United States. The depositary
bank will apply the same method for distributing the proceeds of the sale of any property (such as undistributed rights) held by the custodian in
respect  of  securities  on  deposit. The  distribution  of  cash  will  be  made  net  of  the  fees,  expenses,  taxes  and  governmental  charges  payable  by
holders  under  the  terms  of  the  deposit  agreement. The  depositary  bank  will  hold  any  cash  amounts  it  is  unable  to  distribute  in  a  non-interest
bearing account for the benefit of the applicable holders and beneficial owners of ADSs until the distribution can be effected or the funds that the
depositary bank holds must be escheated as unclaimed property in accordance with the laws of the relevant states of the United States.

Distributions of Shares

Whenever we make a free distribution of ordinary shares for the securities on deposit with the custodian, we will deposit the applicable number
of ordinary shares with the custodian. Upon receipt of confirmation of such deposit, the depositary bank will either distribute to holders new
ADSs representing the ordinary shares deposited or modify the ADS-to-ordinary shares ratio, in which case each ADS you hold will represent
rights and interests in the additional ordinary shares so deposited. Only whole new ADSs will be distributed. Fractional entitlements will be sold
and the proceeds of such sale will be distributed as in the case of a cash distribution.

The distribution of new ADSs or the modification of the ADS-to-ordinary shares ratio upon a distribution of ordinary shares will be made net of
the fees, expenses, taxes and governmental charges payable by holders under the terms of the deposit agreement. In order to pay such taxes or
governmental charges, the depositary bank may sell all or a portion of the new ordinary shares so distributed.

No such distribution of new ADSs will be made if it would violate a law (e.g., the U.S. securities laws) or if it is not operationally practicable. If
the depositary bank does not distribute new ADSs as described above, it may sell the ordinary shares received upon the terms described in the
deposit agreement and will distribute the proceeds of the sale as in the case of a distribution of cash.

Distributions of Rights

Whenever we intend to distribute rights to subscribe for additional ordinary shares, we will give prior notice to the depositary bank and we will
assist the depositary bank in determining whether it is lawful and reasonably practicable to distribute rights to subscribe for additional ADSs to
holders.

The  depositary  bank  will  establish  procedures  to  distribute  rights  to  subscribe  for  additional ADSs  to  holders  and  to  enable  such  holders  to
exercise such rights if it is lawful and reasonably practicable to

30

make  the  rights  available  to  holders  of  ADSs,  and  if  we  provide  all  of  the  documentation  contemplated  in  the  deposit  agreement  (such  as
opinions to address the lawfulness of the transaction). You may have to pay fees, expenses, taxes and other governmental charges to subscribe
for the new ADSs upon the exercise of your rights. The depositary bank is not obligated to establish procedures to facilitate the distribution and
exercise by holders of rights to subscribe for new ordinary shares other than in the form of ADSs.

The depositary bank will not distribute the rights to you if:

• We do not timely request that the rights be distributed to you or we request that the rights not be distributed to you; or
• We fail to deliver satisfactory documents to the depositary bank; or
•

It is not reasonably practicable to distribute the rights.

The depositary bank will sell the rights that are not exercised or not distributed if such sale is lawful and reasonably practicable. The proceeds of
such sale will be distributed to holders as in the case of a cash distribution. If the depositary bank is unable to sell the rights, it will allow the
rights to lapse.

Elective Distributions

Whenever  we  intend  to  distribute  a  dividend  payable  at  the  election  of  shareholders  either  in  cash  or  in  additional  shares,  we  will  give  prior
notice thereof to the depositary bank and will indicate whether we wish the elective distribution to be made available to you. In such case, we
will assist the depositary bank in determining whether such distribution is lawful and reasonably practicable.

The depositary bank will make the election available to you only if it is reasonably practicable and if we have provided all of the documentation
contemplated in the deposit agreement. In such case, the depositary bank will establish procedures to enable you to elect to receive either cash or
additional ADSs, in each case as described in the deposit agreement.

If the election is not made available to you, you will receive either cash or additional ADSs, depending on what a shareholder in France would
receive upon failing to make an election, as more fully described in the deposit agreement.

Other Distributions

Whenever we intend to distribute property other than cash, ordinary shares or rights to subscribe for additional ordinary shares, we will notify
the depositary bank in advance and will indicate whether we wish such distribution to be made to you. If so, we will assist the depositary bank in
determining whether such distribution to holders is lawful and reasonably practicable.

If it is reasonably practicable to distribute such property to you and if we provide to the depositary bank all of the documentation contemplated
in the deposit agreement, the depositary bank will distribute the property to the holders in a manner it deems practicable.

31

The  distribution  will  be  made  net  of  fees,  expenses,  taxes  and  governmental  charges  payable  by  holders  under  the  terms  of  the  deposit
agreement. In order to pay such taxes and governmental charges, the depositary bank may sell all or a portion of the property received.

The depositary bank will not distribute the property to you and will sell the property if:

• We do not request that the property be distributed to you or if we request that the property not be distributed to you;
• We do not deliver satisfactory documents to the depositary bank;
•
•

The depositary bank determines that all or a portion of the distribution to you is not reasonably practicable; or

The proceeds of such a sale will be distributed to holders as in the case of a cash distribution.

Redemption

Whenever  we  decide  to  redeem  any  of  the  securities  on  deposit  with  the  custodian,  we  will  notify  the  depositary  bank  in  advance.  If  it  is
practicable  and  if  we  provide  all  of  the  documentation  contemplated  in  the  deposit  agreement,  the  depositary  bank  will  provide  notice  of  the
redemption to the holders.

The custodian will be instructed to surrender the shares being redeemed against payment of the applicable redemption price. The depositary bank
will  convert  the  redemption  funds  received  into  U.S.  dollars  upon  the  terms  of  the  deposit  agreement  and  will  establish  procedures  to  enable
holders  to  receive  the  net  proceeds  from  the  redemption  upon  surrender  of  their  ADSs  to  the  depositary  bank.  You  may  have  to  pay  fees,
expenses, taxes and other governmental charges upon the redemption of your ADSs. If less than all ADSs are being redeemed, the ADSs to be
retired will be selected by lot or on a pro rata basis, as the depositary bank may determine.

Changes Affecting Ordinary Shares

The ordinary shares held on deposit for your ADSs may change from time to time. For example, there may be a change in nominal or par value,
split-up,  cancellation,  consolidation  or  any  other  reclassification  of  such  ordinary  shares  or  a  recapitalization,  reorganization,  merger,
consolidation or sale of assets of the Company.

If any such change were to occur, your ADSs would, to the extent permitted by law and the deposit agreement, represent the right to receive the
property received or exchanged in respect of the ordinary shares held on deposit. The depositary bank may in such circumstances deliver new
ADSs to you, amend the deposit agreement, the ADRs and the applicable Registration Statement(s) on Form F-6, call for the exchange of your
existing ADSs for new ADSs and take any other actions that are appropriate to reflect as to the ADSs the change affecting the Shares. If the
depositary bank may not lawfully distribute such property to you, the depositary bank may sell such property and distribute the net proceeds to
you as in the case of a cash distribution.

After  the  completion  of  a  global  offering,  the  ordinary  shares  that  are  being  offered  for  sale  pursuant  to  the  prospectus  supplement  in  such
offering will be deposited by us with the custodian. Upon receipt of confirmation of such deposit, the depositary bank will issue ADSs to the
underwriters named in the prospectus.

After  the  closing  of  the  offer,  the  depositary  bank  may  create ADSs  on  your  behalf  if  you  or  your  broker  deposit  ordinary  shares  with  the
custodian.  The  depositary  bank  will  deliver  these ADSs  to  the  person  you  indicate  only  after  you  pay  any  applicable  issuance  fees  and  any
charges and taxes payable for the transfer of the ordinary shares to the custodian. Your ability to deposit ordinary shares and receive ADSs may
be limited by U.S. and French legal considerations applicable at the time of deposit.

The issuance of ADSs may be delayed until the depositary bank or the custodian receives confirmation that all required approvals have been
given and that the ordinary shares have been duly transferred to the custodian. The depositary bank will only issue ADSs in whole numbers.

When you make a deposit of ordinary shares, you will be responsible for transferring good and valid title to the depositary bank. As such, you
will be deemed to represent and warrant that:

The ordinary shares are duly authorized, validly issued, fully paid, non-assessable and legally obtained.

•
• All preemptive (and similar) rights, if any, with respect to such ordinary shares have been validly waived or exercised.
• You are duly authorized to deposit the ordinary shares.
•

The  ordinary  shares  presented  for  deposit  are  free  and  clear  of  any  lien,  encumbrance,  security  interest,  charge,  mortgage  or  adverse
claim, and are not, and the ADSs issuable upon such deposit will not be, “restricted securities” (as defined in the deposit agreement).

•

The ordinary shares presented for deposit have not been stripped of any rights or entitlements.

If any of the representations or warranties are incorrect in any way, we and the depositary bank may, at your cost and expense, take any and all
actions necessary to correct the consequences of the misrepresentations.

Transfer, Combination and Split Up of ADRs

As an ADR holder, you will be entitled to transfer, combine or split up your ADRs and the ADSs evidenced thereby. For transfers of ADRs, you
will have to surrender the ADRs to be transferred to the depositary bank and also must:

•
•
•

ensure that the surrendered ADR is properly endorsed or otherwise in proper form for transfer;

provide such proof of identity and genuineness of signatures as the depositary bank deems appropriate;

provide any transfer stamps required by the State of New York or the United States; and

33

•

pay  all  applicable  fees,  charges,  expenses,  taxes  and  other  government  charges  payable  by ADR  holders  pursuant  to  the  terms  of  the
deposit agreement, upon the transfer of ADRs.

To have your ADRs either combined or split up, you must surrender the ADRs in question to the depositary bank with your request to have them
combined or split up, and you must pay all applicable fees, charges and expenses payable by ADR holders, pursuant to the terms of the deposit
agreement, upon a combination or split up of ADRs.

Withdrawal of Ordinary Shares Upon Cancellation of ADSs

As a holder, you will be entitled to present your ADSs to the depositary bank for cancellation and then receive the corresponding number of
underlying ordinary shares at the custodian’s offices. Your ability to withdraw the ordinary shares held in respect of the ADSs may be limited by
U.S. and French law considerations applicable at the time of withdrawal. In order to withdraw the ordinary shares represented by your ADSs,
you will be required to pay to the depositary bank the fees for cancellation of ADSs and any charges and taxes payable upon the transfer of the
ordinary shares. You assume the risk for delivery of all funds and securities upon withdrawal. Once canceled, the ADSs will not have any rights
under the deposit agreement.

If you hold ADSs registered in your name, the depositary bank may ask you to provide proof of identity and genuineness of any signature and
such  other  documents  as  the  depositary  bank  may  deem  appropriate  before  it  will  cancel  your ADSs.  The  withdrawal  of  the  ordinary  shares
represented by your ADSs may be delayed until the depositary bank receives satisfactory evidence of compliance with all applicable laws and
regulations. Please keep in mind that the depositary bank will only accept ADSs for cancellation that represent a whole number of securities on
deposit.

You will have the right to withdraw the securities represented by your ADSs at any time except for:

•

Temporary delays that may arise because (i) the transfer books for the ordinary shares or ADSs are closed, or (ii) ordinary shares are

immobilized on account of a shareholders’ meeting or a payment of dividends.

• Obligations to pay fees, taxes and similar charges.
• Restrictions imposed because of laws or regulations applicable to ADSs or the withdrawal of securities on deposit.

The deposit agreement may not be modified to impair your right to withdraw the securities represented by your ADSs except to comply with
mandatory provisions of law.

Voting Rights

As a holder, you generally have the right under the deposit agreement to instruct the depositary bank to exercise the voting rights for the ordinary
shares represented by your ADSs. The voting rights of holders of ordinary shares are described in the section of this exhibit entitled “Description
of  Share  Capital-Rights,  preferences  and  restrictions  attaching  to  ordinary  shares-Rights  and  Obligations Attached  to  Ordinary  Shares-Voting
Rights (Article 12 of the Bylaws).”

34

At  our  request,  the  depositary  bank  will  distribute  to  you  any  notice  of  shareholders’  meeting  received  from  us  together  with  information
explaining how to instruct the depositary bank to exercise the voting rights of the securities represented by ADSs. In lieu of distributing such
materials, the depositary bank may distribute to holders of ADSs instructions on how to retrieve such materials upon request.

If the depositary bank timely receives voting instructions from a holder of ADSs, it will endeavor to vote the securities (in person or by proxy)
represented by the holder’s ADSs in accordance with such voting instructions.

If  the  depositary  receives  voting  instructions  from  a  holder  of ADSs  that  fail  to  specify  the  manner  in  which  the  depositary  is  to  vote,  the
depositary  will  deem  such  holder  (unless  otherwise  specified  in  the  notice  distributed  to  holders)  to  have  instructed  the  depositary  to  vote  in
favor of all resolutions endorsed by our Executive Board. With respect to securities represented by ADSs for which no timely voting instructions
are received by the depositary from the holder, the depositary will (unless otherwise specified in the notice distributed to holders) deem such
holder  to  have  instructed  the  depositary  to  give  a  discretionary  proxy  to  a  person  designated  by  us  to  vote  the  securities.  However,  no  such
discretionary proxy will be given by the depositary with respect to any matter to be voted upon as to which we inform the depositary that we do
not wish such proxy to be given, substantial opposition exists, or the rights of holders of securities may be materially adversely affected. Please
note that the ability of the depositary bank to carry out voting instructions may be limited by practical and legal limitations and the terms of the
securities  on  deposit.  We  cannot  assure  you  that  you  will  receive  voting  materials  in  time  to  enable  you  to  return  voting  instructions  to  the
depositary bank in a timely manner.

Amendments and Termination

We  may  agree  with  the  depositary  bank  to  modify  the  deposit  agreement  at  any  time  without  your  consent. We  undertake  to  give  holders  30
days’ prior notice of any modifications that would materially prejudice any of their substantial rights under the deposit agreement. We will not
consider to be materially prejudicial to your substantial rights any modifications or supplements that are reasonably necessary for the ADSs to be
registered under the Securities Act or to be eligible for book-entry settlement, in each case without imposing or increasing the fees and charges
you are required to pay. In addition, we may not be able to provide you with prior notice of any modifications or supplements that are required to
accommodate compliance with applicable provisions of law.

You  will  be  bound  by  the  modifications  to  the  deposit  agreement  if  you  continue  to  hold  your ADSs  after  the  modifications  to  the  deposit
agreement  become  effective. The  deposit  agreement  cannot  be  amended  to  prevent  you  from  withdrawing  the  ordinary  shares  represented  by
your ADSs (except as permitted by law).

We have the right to direct the depositary bank to terminate the deposit agreement. Similarly, the depositary bank may in certain circumstances
on its own initiative terminate the deposit agreement. In either case, the depositary bank must give notice to the holders at least 30 days before
termination. Until termination, your rights under the deposit agreement will be unaffected.

35

After termination, the depositary bank will continue to collect distributions received (but will not distribute any such property until you request
the cancellation of your ADSs) and may sell the securities held on deposit. After the sale, the depositary bank will hold the proceeds from such
sale and any other funds then held for the holders of ADSs in a non-interest bearing account. At that point, the depositary bank will have no
further obligations to holders other than to account for the funds then held for the holders of ADSs still outstanding (after deduction of applicable
fees, taxes and expenses).
In connection with any termination of the deposit agreement, the depositary bank may make available to owners of ADSs a means to withdraw
the ordinary shares represented by ADSs and to direct the depositary of such ordinary shares into an unsponsored American depositary share
program  established  by  the  depositary  bank.  The  ability  to  receive  unsponsored American  depositary  shares  upon  termination  of  the  deposit
agreement  would  be  subject  to  satisfaction  of  certain  U.S.  regulatory  requirements  applicable  to  the  creation  of  unsponsored  American
depositary shares and the payment of applicable depositary fees.

Books of Depositary

The  depositary  bank  will  maintain ADS  holder  records  at  its  depositary  office.  You  may  inspect  such  records  at  such  office  during  regular
business hours but solely for the purpose of communicating with other holders in the interest of business matters relating to the ADSs and the
deposit agreement.
The depositary bank will maintain in New York facilities to record and process the issuance, cancellation, combination, split-up and transfer of
ADSs. These facilities may be closed from time to time, to the extent not prohibited by law.

Limitations on Obligations and Liabilities

The deposit agreement limits our obligations and the depositary bank’s obligations to you. Please note the following:

• We and the depositary bank are obligated only to take the actions specifically stated in the deposit agreement without negligence or bad

faith.

•

•

The depositary bank disclaims any liability for any failure to carry out voting instructions, for any manner in which a vote is cast or for
the effect of any vote, provided it acts in good faith and in accordance with the terms of the deposit agreement.
The depositary bank disclaims any liability for any failure to determine the lawfulness or practicality of any action, for the content of any
document forwarded to you on our behalf or for the accuracy of any translation of such a document, for the investment risks associated
with  investing  in  ordinary  shares,  for  the  validity  or  worth  of  the  ordinary  shares,  for  any  tax  consequences  that  result  from  the
ownership  of  ADSs,  for  the  credit-worthiness  of  any  third  party,  for  allowing  any  rights  to  lapse  under  the  terms  of  the  deposit
agreement, for the timeliness of any of our notices or for our failure to give notice.

• We and the depositary bank will not be obligated to perform any act that is inconsistent with the terms of the deposit agreement.
• We and the depositary bank disclaim any liability if we or the depositary bank are prevented or forbidden from or subject to any civil or

criminal penalty or restraint on account of, or delayed in, doing or performing any act or thing required by the terms of the deposit

36

agreement,  by  reason  of  any  provision,  present  or  future  of  any  law  or  regulation,  or  by  reason  of  present  or  future  provision  of  any
provision  of  our  bylaws,  or  any  provision  of  or  governing  the  securities  on  deposit,  or  by  reason  of  any  act  of  God  or  war  or  other
circumstances beyond our control.

• We and the depositary bank disclaim any liability by reason of any exercise of, or failure to exercise, any discretion provided for in the

deposit agreement or in our bylaws or in any provisions of or governing the securities on deposit.

• We and the depositary bank further disclaim any liability for any action or inaction in reliance on the advice or information received
from legal counsel, accountants, any person presenting Shares for deposit, any holder of ADSs or authorized representatives thereof, or
any other person believed by either of us in good faith to be competent to give such advice or information.

• We and the depositary bank also disclaim liability for the inability by a holder to benefit from any distribution, offering, right or other
benefit that is made available to holders of ordinary shares but is not, under the terms of the deposit agreement, made available to you.
• We and the depositary bank may rely without any liability upon any written notice, request or other document believed to be genuine and

to have been signed or presented by the proper parties.

• We and the depositary bank also disclaim liability for any consequential or punitive damages for any breach of the terms of the deposit

agreement.

• No disclaimer of any Securities Act liability is intended by any provision of the deposit agreement.
• Nothing  in  the  deposit  agreement  gives  rise  to  a  partnership  or  joint  venture,  or  establishes  a  fiduciary  relationship,  among  us,  the

depositary bank and you as ADS holder.

• Nothing in the deposit agreement precludes Citibank (or its affiliates) from engaging in transactions in which parties adverse to us or the
ADS owners have interests, and nothing in the deposit agreement obligates Citibank to disclose those transactions, or any information
obtained  in  the  course  of  those  transactions,  to  us  or  to  the  ADS  owners,  or  to  account  for  any  payment  received  as  part  of  those
transactions.

Whereas pursuant to the Agreement, NN and IPH agreed to work, independently, jointly and/or together with agreed-upon Third Parties, to (a) discover or
identify Drug Candidates, and (b) optimize Drug Candidates for progression to (i) Licensed Products for further development and commercialization by NN or
(ii)  Niche  Candidates  for  further  development  and  commercialization  by  IPH  (either  alone  or  together  with  NN),  in  each  case  for  all  uses  and  purposes,
including therapeutic, prophylactic and, except as otherwise expressly therein provided, diagnostic uses;

Whereas pursuant to Amendment No.1 and with effect from Amendment No.1 Effective Date, NN classified Anti-KIR as a Niche Candidate for independent

further development and commercialization by IPH for any human therapeutic, prophylactic or diagnostic indication or application;

Whereas as a condition precedent to its entry into a license agreement with IPH pursuant to which Bristol-Myers Squibb Company (“BMS”) became an Out-
licensee under the Agreement (the “Out-licensee”), the Parties have executed Amendment No 6 on July 1  2011 clarifying certain matters with respect to the
rights and obligations of the Parties and of BMS with respect to Anti-KIR; and

st

Whereas Anti-Kir or Anti-Kir Antibodies were licensed-out by IPH to BMS under a Collaboration and License Agreement dated July 6th 2011 (the “ BMS
COLA”);

Whereas The development of lirilumab and other Anti-Kir or Anti-Kir Antibodies in a number of Phase I and II clinical trials sponsored by NN, IPH and/or
BMS ended in 2017 for lack of clinical efficacy in Phase 2 trials in several tumor types including Acute Myeloid Leukemia and Head and Neck cancer;

Whereas IPH and BMS would like to terminate their Collaboration and License Agreement and are contemplating the abandonment of all IP rights, patents,
regulatory material and more globally all information related to Anti-Kir or Anti-Kir Antibodies;

Now, therefore, the Parties, intending to be legally bound, agree as follows:

1. The terms defined in the Agreement shall have the meaning herein, unless otherwise defined herein or unless the context otherwise requires. To the
extent that the Agreement is explicitly amended by this Amendment, the terms of the Amendment will control where the terms of the Agreement are
contrary to or conflict with the following provisions. Where the Agreement is not explicitly amended by this Amendment, the terms of the Agreement
will remain in force.

2. The Parties hereby acknowledge that the BMS COLA has been terminated with BMS ceasing to be an Out-Licensee as of July 18  2024.

th

3. With effect from the Effective Date, the Parties hereby agree to partially terminate the JRDOLA with respect to Anti-Kir, Anti-Kir Product or Anti-Kir

Antibodies.

4. As a consequence all rights and obligations of the Parties are terminated with respect to Anti-Kir, Anti-Kir Product or Anti-Kir Antibodies as from the
Effective  Date  and  each  Party  hereby  waive  any  rights  such  Party  may  have  on  the Anti-Kir  or Anti-Kir Antibodies  IP  rights, Anti-KIR  Patents,
regulatory material and more globally all information related to Anti-Kir, Anti-Kir Product or Anti-Kir Antibodies;

5. The Anti-KIR Patents (including Shared Anti-KIR Patents) are listed in Appendix 1.

6. BMS and IPH intends to discontinue the prosecution, maintenance and defense of the Shared Anti-KIR Patents.

7. NN acknowledges BMS and IPH intention to abandon such Shared Anti-KIR Patents and hereby similarly abandon its rights to file, defend, maintain

or continue prosecution of any of such Shared Anti-KIR Patent, at its own expense.

8. NN acknowledges that University of Genoa may choose to file, defend, maintain or continue prosecution of any of such Shared Anti-KIR Patent in

which it has ownership rights.

9. Further, neither BMS nor IPH shall have any obligation to transfer back any IP right, patent or regulatory material, clinical data and more globally all

information related to Anti-Kir, Anti-Kir Product or Anti-Kir Antibodies to NN.

10. All and any remaining payment obligations, if any, with regard to Anti-Kir, Anti-Kir Product or Anti-Kir Antibodies are hereby terminated.

11. Each  Party  hereby  waives  all  rights  it  may  have  under  the  Agreement  on  any  Collaborative  IPR,  Collaboration  Research  Technology  IPR,
Collaboration Patent or Collaboration Know-How on Anti-Kir, Anti-Kir Product or Anti-Kir Antibodies and hereby declares and warrants that it will
not  continue  to  maintain  any  Collaboration  Patent  on Anti-Kir, Anti-Kir  Product  or Anti-Kir Antibodies. Any  intellectual  property  that  might  have
been  created  jointly  by  the  Parties  and/or  that  is  defined  as  Collaborative  IPR,  Collaboration  Research  Technology  IPR,  Collaboration  Patent  or
Collaboration Know-How on Anti-Kir, Anti-Kir Product or Anti-Kir Antibodies will become part of the public domain.

As a consequence, each Party may conduct research on Anti-Kir or Anti-Kir Antibodies. Any new invention or new intellectual property rights that
may  arise  after  the  Effective  Date  from  such  research  activities  performed  individually  by  either  party  will  be  the  property  of  the  Party  having
conducted the research with no right nor any obligation to the others.

12. Each Party hereby waives any action it may have against the other based on or related to Anti-Kir, Anti-Kir Product or Anti-Kir Antibodies rights and

obligations as provided by the JRDOLA.

13. This Amendment shall be deemed an integral part of the Agreement. Except as expressly set forth herein, all provisions of the Agreement shall remain
unchanged and in full force and effect. The Parties expressly affirm their mutual intention that this Amendment to the Agreement shall constitute a
legally binding Amendment to the Agreement.

1 OBJECTIVES OF THE CHARTER

The shares of Innate Pharma (hereinafter, together with its consolidated subsidiaries, the "Group") are listed on
the Euronext regulated market in Paris and, in the form of American Depositary Shares/Receipts (ADS), on the Nasdaq
Select  Global  Select  Market  in  the  United  States.  In  this  context,  compliance  by  Group  employees,  executive  officers
and directors (“Collaborators”) and their relatives with the rules applicable to Securities transactions (as defined below)
and to the holding of Inside Information (as defined below) is crucial for the Group.

These rules are mainly derived from (i) for France, the Regulation of the European Parliament and of the Council
No  596-2014  of  16  April  2014  on  market  abuse,  its  delegated  regulations  and  implementing  regulations  (hereinafter
referred to as the "MAR Regulation"), the Monetary and Financial Code and the regulations of the Autorité des Marchés
Financiers  (AMF)  (hereinafter  referred  to  as  the  "AMF  Regulation"),  and  (ii)  for  the  United  States,  the  Securities
Exchange Act of 1934, as amended (hereinafter, the "1934 Act"), its implementing rules, as adopted by the Securities
and Exchange Commission (the “SEC”) and the case law of the US federal courts.

The purpose of this Market Ethics Charter (the "Charter") is therefore to remind you of the rules applicable to the

Collaborators in stock exchange matters and to explain to you:

– How to behave regarding the information you hold or may hold in connection with your work, mandate or mission

for the Group,

– The  approach  to  be  taken  when  you,  your  family  members  or  other  closely  associated  persons  (as  defined

herein), including legal entities, wish to acquire or sell the Group's financial instruments.
It should be noted that the Collaborators, regardless of their nationality, may be affected by these rules
and/or  those  of  the  country  in  which  they  live  and/or  operate.  In  any  event,  it  is  the  responsibility  of  each
Collaborator  to  read  and  comply  with  the  Charter  and  in  particular  to  personally  ensure  compliance  with  the
various laws that may apply to their situation.

It  is  stressed  that  the  actions  of  each  Collaborator  can  have  consequences  on  the  Group's  image  towards  its
partners  and  the  public,  and  could  expose  the  Group  and/or  the  persons  concerned  to  civil,  criminal  or  administrative
sanctions.

The Charter can be consulted by any interested party on the Group's website (https://www.innate-pharma.com/).
For any additional information relating to the interpretation, use or application of the Charter, you may contact the

Vice-President, Legal & Corporate (market.ethics@innate-pharma.fr).

The Vice-President, Legal & Corporate is responsible for applying the Charter, it being specified that the ultimate

responsibility for compliance with the applicable regulations rests with each Collaborator.

Innate  Pharma  reserves  the  right  to  modify  this  Charter  at  any  time,  to  reflect  legislative,  regulatory  or
jurisprudential developments or to make other improvements. An updated copy of the Charter can be obtained at any
time from the Vice-President, Legal & Corporate.

1 DEFINITION OF INSIDE INFORMATION

Inside Information is defined by MAR as information of a precise nature which has not been made public,
relating, directly or indirectly, to one or more issuers, or one or more financial instruments, and which, if it were
made public, would be likely to have a significant effect on the prices of those financial instruments or on the
price of related derivative financial instruments:

–

Information is deemed to be precise and specific, i.e.: (a) it refers to a set of circumstances that exist or which
may reasonably be expected to come into existence, or an event which has occurred or which may be reasonably
expected  to  occur,  and  (ii)  it  enables  a  conclusion  to  be  drawn  as  to  the  possible  effect  of  that  set  of
circumstances or event on the prices of the relevant financial instruments or the derivative financial instruments.

It  should  be  stressed  that  information  does  not  have  to  be  certain  in  order  to  be  considered  as  Inside
Information. The fact that an event is only likely to occur may constitute Inside Information, even if it does not ultimately
occur.

Further, an intermediate step in a protracted process shall be deemed to be Inside Information if, by itself, it

satisfies the criteria of Inside Information as referred to above.

–

Information  that  has  not  been  made  public  is  information  that  has  not  been  disclosed  to  the  public,  for
example,  by  means  of  a  press  release  published  by  the  Group,  the  Annual  Financial  Report,  the  Universal
Registration  Document  or  the  Half-Year  Financial  Report,  a  prospectus  approved  by  the AMF  or  the  SEC  or  a
financial  notice  published  in  the  financial  press  (and,  with  respect  to  the  United  States,  in  the  annual  report  on
Form 20-F or in a press release or any other publication filed by the Group with the SEC on Form 6-K).

Information that would only be given to a journalist during an interview or a professional conference or to a
financial analyst is not considered to be "public", even if it is taken up by that journalist or financial analysis. Such non-
public information is made public once it has been published by the Group in a press release or in one of the documents
referred to in the previous paragraph.

–

Information that could significantly influence the price of the financial instruments concerned is information
that a reasonable investor would be likely to use as part of the basis of his or her investment decisions.
Inside Information can be negative or positive.
The definition of Inside Information in US federal securities law is essentially jurisprudential, and is usually defined
as material information, which is information for which "there is a substantial likelihood that a reasonable investor would
consider it important in making an investment decision, or if a reasonable investor would view it as altering the total mix
of information available.”

For purposes of this Policy, Inside Information includes information meeting either the MAR definition or
the US securities law definition. Any Collaborator who has knowledge of Inside Information must refrain from
disclosing on his or her own initiative, even within the Group, the information itself, its existence, its nature or
its  possible  impact  and  take  all  necessary  precautions  to  protect  Inside  Information  (in  particular  in
discussions, meetings, note-taking, screen display, reprography, travel, etc.).

Examples of Inside Information
The following information may be considered Inside Information (non-exhaustive list):
important steps in the development of a drug candidate or a Group program (crossing a milestone, submitting a
marketing authorization application, obtaining such an application, etc.),
clinical results,
commercial results,

–
– any signing or termination of any new major or structuring license agreement, scientific, technological, industrial

–

–

collaboration, or problem on the execution of one of these agreements,

– annual, half-yearly, quarterly financial results, or results estimates,
– budgets, financial forecasts, long-term projects,
– development of technologies, products or patents,
– problems in a manufacturing process, quality assurance problems, patent problems,
–

financial  transactions  (securities  issues,  acquisitions,  mergers,  joint  ventures,  financing,  etc.),  including  at  the
drafting stage and even if they are not carried out,

– modification of strategy or investments,
–

changes in key personnel, in particular the departure of a Person Discharging Managerial Responsibilities,
litigation, regulatory issues (ANSM, EMA, FDA in particular),
liquidity problems,
report of a financial analyst who is particularly favourable or unfavourable to the Company,

–
–
–
– any  other  significant  event  having  a  positive  or  negative  influence  on  the  Company's  business,  any  significant

item related to its risk factors.

It should be highlighted that the mere knowledge that the information, if made public, would be likely to have an
effect  on  share  prices  should  be  considered  Inside  Information,  even  if  the  person  in  possession  of  such  information
does not know the precise content of the information.
1 DEFINITION OF THE NOTION OF INSIDER

An "Insider" is a person who has access to Inside Information, because he or she works within the Group
under an employment contract or corporate mandate or because he or she otherwise performs tasks giving him
or her access to such Inside Information. Insiders include:

– Persons  who  hold  Inside  Information  because  of  their  role  or  position  in  or  with  respect  to  the  Group:
Persons  Discharging  Managerial  Responsibilities,  representatives  of  the  Works  Council  (where  applicable),
certain  Collaborators,  statutory  auditors,  collaborators  of  the  CRO  and  CMO  (Contract  Research  Organisation
and  Contract  Manufacturing  Organisation),  consultants,  communication  agencies,  lawyers,  bankers,  other
external advisors, suppliers, subcontractors, etc.

– All other persons with Inside Information who know or should have known that it was Inside Information:
persons outside of the Group and to whom Inside Information has been communicated, voluntarily or by chance.
This category includes, for example, Closely Associated Persons, any other family member or relatives of persons
in the first category, and any person to whom they have communicated Inside Information.
The regulations distinguish, among the above-mentioned persons, two categories of Insiders:

– Permanent Insiders:

These are persons who, because of their functions, have permanent access to all Inside Information

concerning the Group.

Permanent Insiders can belong to two categories:

•

•

persons working within the Group: these include Persons Discharging Managerial Responsibilities, as well as any
collaborator who has or is likely to have regular access to Inside Information.
third parties who maintain regular relations with the Group giving them access to Inside Information: these include
auditors, principal consultants and the usual financial and legal advisors of the Group, its communication agency
and certain companies performing outsourced functions.

Note that not all of these persons are necessarily Permanent Insiders.

– Occasional Insiders:

These  are  persons  within  or  outside  the  Group  who  have  occasional  access  to  Inside  Information
about  the  Group,  in  particular  because  of  their  involvement  in  the  preparation  of  a  particular  transaction  or  their
knowledge of a particular event or circumstance (for example, participation in clinical trials, a commercial agreement, a
dispute, an accident, a financial transaction).

Only  the  CEO  or  the  Vice-President,  Legal  &  Corporate  may  decide  to  include  a  person  on  the  list  of
Permanent Insiders or to disclose Inside Information to an Occasional Insider. However, Collaborators have the

opportunity to identify potential members of their team and third parties to be included in the list of Permanent
Insiders  or  Occasional  Insiders  and  to  ask  the  CEO  or  the  Vice-President,  Legal  &  Corporate  to  include  such
identified persons on the list of Permanent or Occasional Insiders.

Any person identified as an Insider is informed in writing by the Vice-President, Legal & Corporate of his

or her inclusion on an Insider list established by the Group (see Section 5 below).

A person is no longer an Insider once the Inside Information is made public (as described herein). Whether or not

a person is considered to be an Insider may change over time depending on his/her job responsibilities.

1 GROUP OBLIGATIONS
(a) Obligation to disclose Inside Information

In order to ensure equality of investors with regard to information and to prevent insider trading, the Group
must  make  public,  as  soon  as  possible,  by  means  of  a  press  release  and  on  its  website  (https://www.innate-
pharma.com/), any Inside Information likely to have a significant influence on the price of its Securities. This obligation
results from MAR Regulation and the American regulations, but the latter, in particular the Regulation Fair Disclosure,
insists  on  the  obligation  to  communicate  Inside  Information  to  everyone  at  the  same  time  and  sanctions  "selective
disclosure." In MAR, this means that Inside Information may not be communicated outside the normal course of
business, profession or functions.

The information provided must be accurate, precise and sincere.
The Group may defer the publication of Inside Information in limited circumstances and subject to certain

conditions and procedures.

Only the CEO or the Vice President Investors Relations or any person specifically authorised by them for
this  purpose  may  communicate  information  to  the  financial  market  or  the  public  generally,  directly  or  indirectly,  in  any
manner  whatsoever.  It  is  therefore  prohibited  for  any  Person  Discharging  Managerial  Responsibilities  or
Collaborator,  except  with  the  prior  authorization  of  the  CEO  or  the  person  in  charge  of  investors  relations,  to
make statements directly or indirectly to investors, shareholders or, more generally, to the market or the public.

a. Obligation to identify Insiders - Updating of Insider lists

The Group must establish, update and make available to the AMF a list of all persons within the Group who

have access to Inside Information or who perform tasks outside the Group that give them access to Inside Information.

The purpose of the Insider List is to protect the financial markets by allowing the Group to maintain control
over Inside Information, for listed persons to be aware of the obligations and sanctions applicable to them and for the
AMF to investigate possible market abuse more easily.

The  Collaborator  is  informed  of  his  inclusion  on  the  list  as  an  Occasional  or  Permanent  Insider.  The
Collaborator must acknowledge in writing that he or she is aware of the obligations and sanctions applicable to him or
her as a result of being included in the list of Insiders.

The list of Insiders includes the following information about each registered person:

–

the person's identity (surname, first name, date of birth), personal and professional contact information (address,
private and business telephone numbers),

– his or her role, function and the reason for placing the person on the list,
–

the  start  and  end  date  and  time  of  the  person's  access  to  Inside  Information  (with  the  exception  of  Permanent
Insiders).

Pursuant to Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 on
the  protection  of  individuals  with  regard  to  the  processing  of  personal  data  and  on  the  free  movement  of  such  data
(General Data Protection Regulation), each registered person has a right of access to personal information concerning
him/her with a view to its possible correction in the event of error, this right may be exercised with Innate’s designated
“Data Protection Officer” (dpo@innate-pharma.fr).

The  list  of  Insiders  shall  be  kept  for  at  least  five  years  from  the  date  of  its  establishment  or  update.  It  is

confidential, except to the AMF, which can obtain it on request.

1 OBLIGATIONS OF THE INSIDERS
(a) Insider Confidentiality Obligation

Any person who holds Inside Information must refrain from disclosing it to another person, including

within the Group.

Consequently,  any  Insider  must  maintain  the  confidentiality  of  Inside  Information  with  respect  to  any  person,

including within the Group.

Insiders  also  refrain  from  spreading  rumours,  whether  through  the  media  (including  the  Internet)  or  by  any
other  means,  that  give  or  are  likely  to  give  false  or  misleading  information  about  the  Securities  and/or  the  situation,
results or prospects of the Group.

Consequently, all Collaborators must constantly protect access to documents referring to Inside Information, in
particular  by  limiting  the  number  of  copies  to  the  strict  minimum,  ensuring  the  security  of  exchanges  and  meetings
carried out in the form of conference calls or videoconferences, keeping documents in secure areas, ensuring that they
are destroyed by secure means and using code names.

Insiders are strictly prohibited from engaging in “Tipping.” Tipping is disclosing Inside Information concerning
the  Group  or  making  recommendations  or  expressing  opinions  on  the  basis  of  Inside  Information  as  to  trading  in
Securities to any person or entity who might be expected to trade while in possession of that information, other than in
the  necessary  course  of  business,  (including,  but  not  limited  to  spouse,  family  members  and  friends  or  other  Closely
Associated Persons, social acquaintances, investors, financial analysts, consulting firms and former Insiders). Tipping is
strictly  prohibited  under  this  Charter  and  this  prohibition  applies  whether  or  not  the  person  disclosing  the  Inside
Information receives any benefits from the use of that information by the other person or entity.

Any  Collaborator,  who  has  doubts  about  the  content  of  the  information  he  or  she  may  communicate,  in
particular  during  an  oral  intervention  or  written  presentation,  may  refer  the  matter  to  the  Vice-President,  Legal  &
Corporate (market.ethics@innate-

pharma.fr). If in doubt or awaiting a response from Vice-President, Legal & Corporate, the information in question must
not be disclosed.

The prohibition to use or disclose Inside Information is applicable throughout the year.
In  addition,  it  is  essential  to  immediately  notify  the  Vice-President,  Legal  &  Corporate  if  Inside
Information  concerning  the  Group  has  been  disclosed  outside  the  normal  procedures  for  disseminating
information (for example at internal or external meetings, seminars or colloquia).

(a) Obligation to refrain from trading in the Securities

The  applicable  laws  and  regulations  on  insider  trading  prohibit  any  Insider  from  using  Inside  Information  by
acquiring or disposing of, for its own account or for the account of a third party, directly or indirectly, Innate Securities.
The  use  of  Inside  Information  by  cancelling  or  amending  an  order,  where  the  order  was  placed  before  the  person
concerned possessed the Inside Information, is insider dealing.

It is also prohibited to recommend, on the basis of Inside Information, that another person acquire or dispose of

Innate Securities (cancel or amend an order), or induces that person to make such an acquisition or disposal.

It is further prohibited to communicate Inside Information to any other person, except where the disclosure is
made  in  the  normal  exercise  of  an  employment,  a  profession  or  duties,  is  also  prohibited  (“need  to  know  basis”
exception).

It is recalled that the legal obligation to abstain applies in the event of holding Inside Information concerning all
listed securities, even those other than Group Securities, and in particular the securities of listed companies with which
the Group may come to work, if applicable. Given the repercussions that this would have for the Group, it would be a
violation of the Charter for a Collaborator to carry out a transaction on the Securities of another company on the basis of
Inside Information gathered in the course of his duties within the Group.

Generally  speaking,  the  period  between  the  date  on  which  a  person  comes  into  possession  of  Inside
Information  and  the  trading  session  following  the  date  on  which  the  same  information  is  made  public  is  necessarily  a
period of abstention for that person and their Closely Associated Persons. In the event of a major event brought to the
attention  of  a  significant  number  of  Collaborators  (examples:  clinical  trial  results,  financial  transactions,  licensing
agreements,  etc.),  Innate’s  Legal  Department  may  notify  the  persons  concerned  by  email  of  the  opening  of  an
abstention  period.  However,  such  information  will  not  be  systematic  and  the  absence  of  notification  of  such  an
abstention  period  would  not  in  any  way  exempt  a  Collaborator  who  carries  out  an  insider  trading  from  otherwise
complying  with  this  Charter.  In  addition,  the  existence  of  such  a  period  of  abstention  may  in  itself  constitute  Inside
Information.

It  is  recalled  that  in  case  of  doubt,  each  employee  may  request  the  views  of  the  Vice-President,  Legal  &
Corporate on the possibility of trading in Group Securities. However, such views do not constitute an authorization, as
each applicant remains personally responsible for his or her acts.

It should be noted that all Closely Associated Persons, and more generally all persons who, because of

their relationships with persons holding

Inside Information, could be suspected of having exploited Inside Information provided by such Insider.

Insider status and the related above prohibitions shall continue to apply even after the person concerned has

left the Group, as long as the Inside Information held has not been made public.

Preventive abstention periods ("negative windows" or “black-out periods”)

– With  due  regard  to  the  general  abstention  obligation  described  above,  the  Group  will  set  abstention  periods
("negative  windows"  or  "black-out  periods")  during  which  Permanent  Insiders,  Persons  Discharging  Managerial
Responsibilities,  and  potentially  certain  Group  Collaborators  must  refrain  from  buying,  selling  or  carrying  out
transactions,  directly  or  indirectly,  on  their  behalf  or  on  behalf  of  others,  on  Group  Securities  or  exercising
warrants (BSA) or redeemable (BSAAR), selling shares issued from AGA or AGAP[1], or carrying out transactions
in Securities whose underlying is a Group Security.

During these abstention periods as described below, Permanent Insiders, Persons Discharging Managerial
Responsibilities, and potentially certain Collaborators are not authorised to carry out Transactions on Group Securities
whether or not they hold Inside Information.

Abstention  periods  are  first  of  all  short,  predictable  periods  during  which  significant  and  non-public

information about the Group circulates within the Group.

These periods are defined as follows:

– at least 15 days prior to the publication of quarterly financial results;
– at least 30 days before the publication of the half-year and annual financial results.

It  should  be  noted  that,  in  exceptional  circumstances,  these  periods  may  begin  earlier  than  the  dates
indicated above, in which case the Collaborators would be informed (this information may constitute Inside Information).
In addition to the abstention periods provided for by the texts, the Company may set up additional blackout

periods introduced on an ad hoc basis prior to certain events.

Transactions  are  only  possible  again  as  from  the  trading  session  following  the  publication  concerned,

provided that they are not in a negative window or that they do not hold any other Inside Information.

An e-mail is sent to involved Collaborators and Persons Discharging Managerial Responsibilities to inform
them  of  these  periods.  The  financial  communication  calendar  is  also  available  to  any  interested  party  on  the  Group's
Internet and Intranet site.

Nevertheless, the absence of e-mail would in no way exempt a Collaborator from liability in the event of a

breach or violation of this Charter.

These negative windows continue to apply even after the person concerned has left the Group for as long as

he or she possesses Inside Information.
(i) Obligation to inform the Group

In  order  to  ensure  compliance  with  the  Charter  within  the  Group,  Collaborators  must  implement  all

measures to prevent violations of the Charter, in particular:

–

–

inform the Vice-President, Legal & Corporate, when they believe they are in possession of information that is not
yet  public  and  which,  by  its  nature,  could  constitute  Inside  Information,  and  should  refrain,  pending  the
qualification  of  such  information,  from  disclosing  the  information  and,  if  so,  communicate  to  the  Vice-President,
Legal & Corporate without delay the list of persons informed;
remind those of their subordinates who are called upon to work on sensitive subjects relating to the existence and
content of the Charter;

– promptly notify the Vice-President, Legal & Corporate if Inside Information has been disclosed.

Collaborators are reminded that the implementation of these preventive measures in no way exempts them

from administrative or criminal liability in the event of an offence.
1 OFFENCES AND APPLICABLE INCURRED SANCTIONS

Persons who do not comply with the rules relating to the use and disclosure of Inside Information may be subject
to administrative sanctions imposed by the AMF and the SEC, or to criminal sanctions imposed by the judicial, French or
American federal authorities, as well as disciplinary sanctions within the Group.

French criminal and administrative sanctions
Violations of these prohibitions may result in the following criminal or administrative sanctions (L.465-1 et al. and

L.621-15 III of the Code monétaire et financier):

– a fine or financial penalty imposed by the AMF of up to €100 million or, if profits have been made, ten times the

amount, and

– up to five years' imprisonment imposed by the criminal court

Such behaviour may be punished even in the absence of profit or benefit for the perpetrator. In particular, avoiding
losses (by selling Securities before bad news is announced) will be sanctioned and the amount of loss avoided will be
taken into consideration in determining the fine or monetary penalty. The attempt is also subject to sanctions.

As a reminder, conduct punishable under criminal law and by the AMF also includes price manipulation and the

dissemination of false information (Article 12 of the MAR Regulation).

U.S. Sanctions
Insider  trading  may  result  in  an  enforcement  action  by  the  supervisory  authorities,  in  criminal  prosecution,  or  in
civil lawsuits seeking damages. Persons who have violated the U.S. rules and regulations relating to the prevention of
insider trading may be liable in the United States for civil penalties of up to three times the amount of profits made or
losses  avoided  through  insider  trading,  and  criminal  fines  of  up  to  $5  million  for  individuals  and  $25  million  for
corporations. Jail sentences can also be imposed for up to 20 years.

Disciplinary sanctions
Any violation of this Charter and these rules or the law on misdemeanours or breaches of duty by an Executive
Officer or Collaborator, or a member of their families, may result in measures up to and including dismissal of the person
concerned.

The  commission  of  an  offence  or  breach  by  an  Insider  is  the  responsibility  of  the  person  who  commits  it.  The
Group  disclaims  any  liability  of  or  responsibility  for  any  person  who  has  committed  insider  trading  in  violation  of  this
Charter. As such, the Group does not intend to assume the fines to which its Collaborators may be liable.

Anyone who is in breach of the rules contained in this Charter or who becomes aware of the occurrence of such a
breach  by  another  person  must  immediately  inform  the  Compliance  Officer  or  the  Vice-President,  Legal  &  Corporate,
who will take all appropriate measures internally and vis-à-vis the market authorities.

1 OBLIGATIONS OF RETENTION AND DISCLOSURE OF TRANSACTIONS CARRIED OUT BY THE OFFICERS

In  accordance  with  the  MAR  Regulation,  Persons  Discharging  Managerial  Responsibilities  and  their  Closely
Associated Persons must comply with specific obligations relating to the custody of their Securities and the reporting of
their Transactions.

Obligation to notify the Closely Associated Persons of their obligations
Each  of  the  Persons  Discharging  Managerial  Responsibilities  must  notify  in  writing  their  Closely  Associated
Persons  of  their  obligations  under  the  MAR  Regulation  and  keep  a  copy  of  this  notification.  They  must  also  inform
Innate  (Vice-President,  Legal  &  Corporate)  of  who  their  Closely  Associated  Persons  are,  as  Innate  must
maintain a list of them.

Obligation to hold registered shares
Members of the Board and the CEO, as well as their spouses who are not separated and minor children who are
not emancipated, must hold, within the prescribed time limits, all the Securities they hold in registered form with Société
Générale  Securities  Services  or  in  registered  form  administered  with  an  intermediary  (bank,  financial  institution  or
investment services provider) of their choice.

The voting rights and dividend rights of shares held by any person who has not fulfilled these obligations shall be

suspended until the situation is regularised. Any vote cast or dividend payment made during the suspension is void.

Reporting obligations for Transactions in Securities
The  MAR  Regulation  require  Persons  Discharging  Managerial  Responsibilities  and  their  Closely  Associated
Persons  to  communicate  directly  to  the  AMF,  which  makes  them  public,  the  acquisitions,  sales,  subscriptions  or
exchanges  of  Group  shares.  These  people  are  on  a  list  that  is  regularly  updated  by  the  Group.  They  are  required  to
refrain from any Transaction as soon as they become aware of Privileged Information.

– Operations covered: all operations to buy, sell, subscribe or exchange the Group's "financial instruments", i.e.
not only shares but also other securities giving access to the capital (warrants, BSAARs, shares issued from AGA
and AGAP, etc.).

– Trigger threshold: publication is not required as long as the total cumulative amount of transactions carried out

by a data subject does not exceed €20,000 over a calendar year.

– Reporting procedures: The declaration must be submitted to the AMF no later than three business days from

the date of the Transaction.

This  declaration  must  be  sent  to  the AMF,  by  electronic  means  only  via  an  extranet  called  Onde,  which
makes it possible to complete the mandatory form, which can be accessed on the AMF website at the following address:

https://onde.amf-france.org/RemiseInformationEmetteur/Client/PTRemiseInformationEmetteur.aspx
Declarations may be transmitted to the AMF by the person required to report or by a third party on behalf of

the declarant, the identity of the applicant must be clearly indicated in the declaration form.

The  AMF  publishes  these  declarations  on  its  website,  which  are  also  summarized  in  the  management
report presented to the Innate Pharma Annual General Meeting and in the Group's Universal Registration Document, if
applicable.

Persons  Discharging  Managerial  Responsibilities  are  also  required,  at  the  Vice-President,  Legal  &
Corporate’s request, to declare the number and nature of the Securities they hold, as well as any relevant information on
the holding of Securities (e. g. stripping, promise to acquire or sell, pledge, etc.).

It should be noted that these obligations are distinct from those relating to the crossing of thresholds, which
exist under French law and US federal stock market law and are applicable whether or not the shareholder is a Member
of the Management.

There are no equivalent obligations in the United States for directors and officers of foreign private issuers other

than the specific obligations applicable to shareholders holding at least 5% of the capital.

[1]  Regarding  the  owners  of  shares  issued  from AGA  or AGAP,  the  30-day  abstention  period  (at  least)  preceding  the
annual and half-year financial results publication is provided by Article L.22-10-59 of the French Code of Commerce
