Summary of the Material Risks Associated with Our Business

Our business is subject to numerous risks and uncertainties that you should be aware of in evaluating our business. These risks include, but are not limited to, the following:

As a company, we have a limited operating history and limited experience commercializing pharmaceutical products and have incurred significant losses since inception.
We may never be profitable or be able to sustain revenues or, if achieved, sustain profitability in the future and we may not be able to continue operations without additional fundings.
We may require additional capital to sustain our business, and this capital may cause dilution to our stockholders and might not be available on terms favorable to us, or at all, which
could force us to delay, reduce or eliminate our product development programs or commercialization efforts.
Our business depends entirely on the commercial success of our products and product candidates. Even if approved, our product candidates may not be accepted in the marketplace and
our business may be materially harmed.

We  operate  in  a  competitive  business  environment,  which  may  have  an  adverse  impact  on  our  revenue.  If  we  are  unable  to  compete  successfully  against  our  existing  or  future
competitors, our sales and operating results may be negatively affected and we may not successfully commercialize our products or product candidates, even if approved.

If we are unable to establish or do not maintain sufficient marketing, sales and distribution capabilities or enter into agreements with third parties to market, sell and distribute our
products on terms acceptable to us, we may not be able to generate product revenue and our business, results of operations, and financial condition will be materially adversely affected.
Our reliance on third-party suppliers, including single-source suppliers, together with a limited number of possible suppliers and long development lead-times for alternate sources for
Gvoke, Recorlev and Keveyis or our product candidates could harm our ability to develop our product candidates or to continue to commercialize Gvoke, Recorlev, Keveyis, or any
product candidates that are approved.
Reimbursement decisions by third-party payors and consolidation within the healthcare industry and among competitors may have an adverse effect on pricing and market acceptance.
If there is not sufficient reimbursement for our products, it is less likely that they will be widely used and pricing pressure may impact our ability to sell our products at prices necessary
to support our current business strategies.
Clinical failure may occur at any stage of clinical development, and the results of our clinical trials may not support our proposed indications for our product candidates. If our clinical
trials fail to demonstrate efficacy and safety to the satisfaction of the Food and Drug Administration ("FDA") or other regulatory authorities, we may incur additional costs or experience
delays in completing, or ultimately be unable to complete, the development of such product candidate.
Gvoke, Recorlev, Keveyis and our product candidates may have undesirable side effects which may delay or prevent marketing approval, or, if approval is received, require them to
include safety warnings, require them to be taken off the market or otherwise limit their sales.

Our  failure  to  successfully  identify,  develop  and  market  additional  product  candidates,  or  acquire  additional  product  candidates  or  enter  into  collaborations  or  other  commercial
agreements could impair our ability to grow.

Our success depends on our ability to protect our intellectual property and proprietary formulation science, as well as the ability of our collaborators to protect their intellectual property
and proprietary formulation science.
Our stock price has been and will likely continue to be volatile, and you may lose part or all of your investment.

Our  data  collection  and  processing  activities  are  governed  by  restrictive  regulations  governing  the  use,  processing  and,  in  certain  jurisdictions,  cross-border  transfer  of  personal
information.

The summary risk factors described above should be read together with the text of the full risk factors below in the section entitled "Risk Factors" and the other information set forth in this Annual
Report on Form 10-K, including our consolidated financial statements and the related notes, as well as in other documents that we file with the United States Securities and Exchange Commission.
The risks summarized above or described in full below are not the only risks that we face. Additional risks and uncertainties not precisely known to us or that we currently deem to be immaterial may
also materially adversely affect our business, financial condition, results of operations and future growth prospects.

PART I

ITEM 1. BUSINESS

As used herein, the "Company", "Xeris", "we" or "our" refers to Xeris Biopharma Holdings, Inc. ("Xeris Biopharma"). Throughout this document, unless otherwise noted, references to Gvoke include
Gvoke PFS, Gvoke HypoPen, Gvoke Kit and Ogluo.

Overview

We  are  focused  on  building  an  innovative,  self-sustaining,  growth-oriented  biopharmaceutical  company  committed  to  improving  patients’  lives  by  developing  and  commercializing  clinically
meaningful products across a range of therapies. We are uniquely positioned to achieve this through our three commercial products and our proprietary formulation science (XeriSol and XeriJect),
which generates partnerships and enhances our product candidates.

Commercial Products

Our top priority is maximizing the potential of our three commercial products:

• Gvoke is a ready-to-use, liquid-stable glucagon for the treatment of severe hypoglycemia. The product is indicated for use in pediatric and adult patients with diabetes age two years and

above and can be administered in two simple steps. The estimated total addressable market for this drug is approximately $5.0 billion in the United States.

•

•

Recorlev is a cortisol synthesis inhibitor approved for the treatment of endogenous hypercortisolemia in adult patients with Cushing’s syndrome for whom surgery is not an option or has not
been curative. Endogenous Cushing’s syndrome is a rare but serious and potentially fatal endocrine disease caused by chronic elevated cortisol exposure. The estimated total addressable
market for this therapy is approximately $3.0 billion in the United States.

Keveyis is the first therapy approved in the United States to treat hyperkalemic, hypokalemic, and related variants of Primary Periodic Paralysis ("PPP"). PPP is a rare genetic, neuromuscular
disorder that can cause extreme muscle weakness and/or paralysis; some forms are also commonly associated with myotonia or muscle stiffness. The estimated total addressable market for
this therapy is greater than $0.5 billion in the United States.

Our Proprietary Formulation Capabilities

Our company name, Xeris, is derived from the ancient Greek word xērós meaning 'dry' or 'without water/non-aqueous'. Our proprietary, non-aqueous formulation capabilities are designed to enable
the convenient injection of medicines previously uninjectable or poorly injectable when utilizing aqueous approaches. Both XeriSol and XeriJect offer the opportunity to create ready-to-use, room-
temperature stable, highly concentrated, injectable formulations of both small and large molecules. These proprietary formulation capabilities can enable subcutaneous (SC) or intramuscular (IM)
administration in lieu of intravenous (IV) infusion, allow for convenient, cost-effective storage, and provide an improved patient, caregiver, and healthcare provider experience. XeriSol and XeriJect
have broad applications and enable us to develop our own internal product development candidates in endocrinology, neurology and other therapeutic areas. They also enable us to pursue formulation
and development partnerships pursuant to which our proprietary formulation science is applied with the goal of enhancing the product formulation, delivery and clinical profile of other companies’
proprietary drugs and biologics.

Table of Contents

Our Strategy

Our goal is to build a growth-oriented, self-sustaining biopharmaceutical company by developing and commercializing differentiated and innovative products across a range of therapies that improve
patients' lives. To achieve our goal, we are pursuing the following strategies:







Drive revenue growth through effective commercial execution of our innovative products. We have three innovative commercial assets (Gvoke, Recorlev and Keveyis) all
of  which  fill  unique,  unmet  needs.  Additionally,  Gvoke  and  Recorlev  are  in  the  early  stages  of  their  product  lifecycles  and  both  leverage  our  experienced  and  growing
leadership presence in the endocrinology community. Executing against the opportunities made possible by Gvoke, Recorlev, and Keveyis should maintain our momentum of
growth and enable the financial self-sufficiency of our Company.
Continue to leverage our proprietary formulation science and expertise to develop our internal new product candidates. We have established a proven capability to bring
new and innovative products through the development and regulatory process to successful commercialization. XeriSol and XeriJect have broad application and have the
potential  to  be  utilized  across  a  range  of  potential  product  candidates  in  multiple  therapeutic  areas.  Our  immediate  focus  is  on  developing  XP-8121,  a  once  weekly
subcutaneous injection of levothyroxine and eventually generating significant benefits for patients and value for our company.
Collaborate with pharmaceutical and biotechnology companies to apply our proprietary formulation science to enhance the formulations of their proprietary products
and candidates. We are pursuing formulation and development partnerships to apply our XeriJect and XeriSol formulation platforms to enhance the drug delivery and clinical
profile of other companies’ proprietary drugs and biologics. We are currently collaborating with several major pharmaceutical companies on the development of formulations
of their proprietary therapeutics with XeriJect. Our strategic goal is to ultimately enter into commercial licensing agreements with these partners upon successful completion
of formulation development.

We believe these three pillars of our strategy can bring new products to market and transform the lives of patients with life-impacting diseases and ultimately drive value for Xeris’ shareholders.
Pursuing these strategies provides Xeris with a range of value driving opportunities that are incremental to the value already realized by the Xeris enterprise.

Our Products

Gvoke

Gvoke is our ready-to-use, room-temperature stable, liquid glucagon product. Available since late 2019, Gvoke is a potentially life-saving rescue product that is designated to be reliably administrated
by the individual with diabetes or their caregivers during low blood sugar emergencies (e.g., a severe hypoglycemic episode). Gvoke is available in three presentation types - HypoPen (auto-injector),
PFS (pre-filled syringe), and Kit (pre-filled vial and administration syringe). Our most widely prescribed presentation, HypoPen, is designed to be administered subcutaneously in a simple two-step
process requiring no dose calibration.

The marketplace for Gvoke and other ready-to-use glucagon products is significant, owing to the widespread and growing prevalence of diabetes, the large proportion of people with diabetes at risk
of experiencing a severe hypoglycemic event, and the still limited awareness of the availability of innovative, ready-to-use glucagon.

We participate in this market primarily with Baqsimi, a ready-to-use nasally administered glucagon powder, which was launched in mid-2019 and acquired by Amphastar Pharmaceuticals, Inc. in
June 2023. Our promotional efforts to create awareness of Gvoke have helped expand the market for rescue glucagon by more than 60%, enabled us to capture an over 30% share of the overall
glucagon rescue retail market as of December 31, 2023, and generated approximately a quarter million prescriptions since launch.

Table of Contents

The  most  recent  Standards  of  Care  established  by  the  American  Diabetes  Association,  the  American  Academy  of  Clinical  Endocrinologists,  and  the  Endocrine  Society,  all  advise  that  patients  at
increased risk of dangerously low blood sugar should be prescribed a ready-to-use glucagon. We estimate that at least half of the approximately 30 million people with diabetes in the United States
fall into this at-risk category and should be prescribed and have handy, a ready-to-use rescue glucagon, like the Gvoke HypoPen for use during a potential severe hypoglycemic episode. Current
prescription volumes suggest that approximately 1 million people with diabetes are adequately protected today, leaving a significant number of people without protection as recommended by the
latest guidelines. If all at risk persons were adequately protected, the market potential is estimated to be nearly $5.0 billion annually.

Our commercial team and sales force are focused on driving awareness and adoption of Gvoke by healthcare professionals, patients and caregivers.

Recorlev

Recorlev is our new therapy approved in 2022 for the treatment of Cushing’s syndrome, a rare condition which is the result of sustained, elevated levels of cortisol in the body (hypercortisolism).
Cushing’s syndrome affects approximately 25,000 people in the United States of which approximately two-thirds are cured by surgery. Pharmacologic products like Recorlev are used for the balance
of patients for whom surgery was not curative or was not indicated. Recorlev has received orphan drug exclusivity status in the United States through December 30, 2028.

We believe that the Cushing’s syndrome market in the United States is approximately $3.0 billion annually. Recorlev competes primarily with other established medications and therapies, including
older generic drugs that are used off-label for Recorlev's approved indication. Signifor (pasireotide) Injection and Isturisa (osilodrostat) are approved for Cushing’s Disease, a subset of Cushing’s
syndrome and sold by Recordati S.p.A. Korlym (mifepristone) is approved for the treatment of hyperglycemia secondary to

8

Table of Contents

hypercortisolism in Cushing’s syndrome patients and sold by Corcept Therapeutics. Because of the complex nature of Cushing’s syndrome, many patients are inadequately treated with currently
available medicines.

Our experienced commercial organization focuses on educating prescribing clinicians and patients to raise awareness of the benefits of normalizing cortisol with Recorlev. Xeris’ Care Connection
program provides direct, dedicated support to treating clinicians and patients throughout their Recorlev journey. In addition, our efforts include the support of a single, highly experienced specialty
pharmacy that provides logistical assistance in the securing of coverage from third-party payors and then subsequent distribution of Recorlev to the patients.

Keveyis

Keveyis (dichlorphenamide) is the first FDA-approved therapy for the treatment of the ultra-rare condition of PPP. PPP is an inherited group of neuromuscular conditions that are characterized by
interference with the electrical-chemical communications between nerve cells and skeletal muscles that can cause paralytic attacks.

PPP is estimated to affect approximately 4,000 to 5,000 people in the United States. Our promotional efforts are aimed at bringing awareness of this condition to both the healthcare professionals and
patient communities.

Patient identification, capture, and retention in ultra-rare markets is extremely difficult and time-consuming. To address this, we have built an extensive set of patient support processes and proprietary
analytics to identify patients affected by PPP and suitable for Keveyis therapy treatment. We also employ a specialty pharmacy to assist with the navigation of complex payer, healthcare professionals
and patient support requirements for this ultra-rare disease.

Since our purchase of Keveyis through the acquisition of Strongbridge, we have been planning and projecting for the loss of orphan drug exclusivity status, which occurred in August 2022. We also
continue to seek patents to restore our exclusive rights. We currently have two United States patent applications pending with claims protecting therapeutic uses of Keveyis. Both of these patent
applications are on appeal at the United States Court of Appeals for the Federal Circuit. In late 2022, the FDA approved a generic version of our Keveyis product.     

Our proprietary Formulation Platforms

Overview

In the presence of water, many drugs have poor solubility and stability. Our proprietary non-aqueous formulation science is designed to address the challenges associated with formulating certain
drugs and overcome the inherent limitations of conventional aqueous-based formulation approaches. Injectable pharmaceuticals have conventionally been developed using aqueous formulations. To
optimize their stability and enable longer-term storage, many of these products are freeze dried into a powder and, when needed, must be reconstituted with an aqueous diluent. This is typically
associated with a challenging multi-step procedure with significant potential for error. Furthermore, these drugs can begin to break down once combined with water, which requires the reconstituted
product to be used immediately or otherwise be refrigerated. In addition, many of these drugs can require complicated formulations and large injection volumes to make them soluble. For many
products, these volumes are too large for SC or IM delivery and instead necessitate IV infusion over several hours. These products can be difficult or painful to administer and have limited portability,
resulting in an overall poor experience for patients and caregivers.

Our  proprietary  non-aqueous  XeriSol  and  XeriJect  technologies  offer  the  opportunity  to  eliminate  the  need  for  reconstitution  and  refrigeration,  enable  long-term  room-temperature  stability,
significantly  reduce  injection  volume,  and  allow  for  a  more  convenient  SC  or  IM  administration  as  opposed  to  IV  infusion  and  other  routes  of  administration.  We  believe  these  present  distinct
advantages over existing aqueous formulation approaches for currently marketed products and development-stage product candidates.

The proprietary XeriSol non-aqueous formulation platform is designed to address the limitations of aqueous formulations for peptide and small molecule drugs. The solutions are formulated using
biocompatible, non-aqueous solutions that impart high stability and solubility to drugs allowing for development of room temperature stable, ready-to-use formulations. XeriSol formulations have
been used extensively in global commercial products (Gvoke/Ogluo) and clinical trials.

The proprietary XeriJect non-aqueous formulation platform is designed as an innovative, ready-to-use, viscoelastic pharmaceutical suspension that has the potential to improve drug delivery, lower
treatment  burden  and  improve  patients'  lives  across  a  broad  range  of  therapeutic  categories.  XeriJect  suspensions  maximize  drug  loadings  at  >400mg/mL,  enable  small  volume  subcutaneous
injections  and  do  not  settle  on  storage.  The  suspensions  use  FDA-approved  excipients  and  leverage  known  manufacturing  processes.  XeriJect  formulation  science  is  well  suited  for  drugs  and
biologics including large molecules such as proteins, monoclonal antibodies, and vaccines.

The formulation science associated with both the XeriSol and XeriJect technologies is protected by an extensive patent estate, trade secrets and know-how, and it is available for licensing. We believe
that our scientific formulation capabilities can lead to products that will improve outcomes and enable easier administration while reducing costs for payors and the healthcare system.

Our Product Candidates

Once Weekly Subcutaneous Injection of Levothyroxine (XP-8121)

XP-8121 is a novel formulation for subcutaneous administration that could potentially mitigate many of the challenges associated with oral formulations, such as identification of an ideal dose due to
absorption variation and medication adherence for patients who have difficulty maintaining a stable, therapeutic serum level. Preclinical studies of XP-8121 showed a sustained plasma exposure
profile

9

Table of Contents

and  similar  highest  concentration  of  a  drug  in  the  blood,  or  Cmax,  when  compared  with  equivalent  doses  of  the  oral  formulation.  We  conducted  a  Phase  1  study  of  XP-8121  to  evaluate  the
pharmacokinetics, safety and tolerability, and potential for weekly dosing in the treatment of hypothyroidism.

Levothyroxine and Hypothyroidism

The thyroid gland is responsible for the synthesis, storage, and release of metabolic hormones including thyroxine (T4) and triiodothyronine (T3). These hormones are crucial in the regulation of
critical metabolic processes and are vital for normal growth and development during fetal life, infancy, and childhood.

Therapeutically,  levothyroxine  is  administered  as  a  replacement  for  deficient  thyroid  hormones.  The  goal  of  the  therapy  is  restoration  of  the  euthyroid  state  which  can  reverse  the  clinical
manifestations  of  hypothyroidism  and  significantly  improve  quality  of  life.  The  treatment  of  choice  for  correction  of  hypothyroidism  is  currently  continuous  daily  oral  administration  of
levothyroxine. It is one of the most widely prescribed drug products in the United States, but the complexity of maintaining biochemical and clinical euthyroidism in patients undergoing treatment
with oral levothyroxine is challenging. It has been reported that nearly 40% of patients undergoing treatment with oral levothyroxine are either over- or under-treated due to factors that include, but
are not limited to, drug formulation, use of the drug with food, adherence to the drug, use of concomitant medications, and pre-existing medical conditions. Many patients failing to reach target
thyroid  stimulating  hormone  ("TSH")  levels  are  managed  by  simply  increasing  their  levothyroxine  daily  dose.  However,  levothyroxine  is  a  drug  with  a  narrow  therapeutic  index,  meaning  that
relatively small deviations from the proper dose can cause a clinically meaningful shift in pharmacological effects when administered to a patient; thus, the titration of levothyroxine oral drug may be
a tailored and incremental process.

The Phase 1 clinical study was a single ascending dose crossover design in 30 healthy participants to compare matching doses of oral levothyroxine (Synthroid) and subcutaneous XP-8121. The
primary endpoints of the study were to characterize the absorption and elimination kinetics of XP-8121 and compare bioavailability of XP-8121 to oral levothyroxine. Secondary endpoints were
safety and tolerability of XP-8121.

In  October  2022,  we  reported  positive  topline  Phase  1  data  of  XP-8121.  The  data  showed  that  subjects  receiving  XP-8121  subcutaneous  had  slower  absorption,  lower  peak  plasma,  and  higher
extended exposure compared to Synthroid PO at the comparable dose of 600 μg. In addition, exposure was proportional over the range of ascending XP-8121 doses studied. Simulations based on a
population pharmacokinetic model indicated that exposure from weekly XP-8121 1200 μg SC doses overlapped daily Synthroid PO 300 μg suggesting a dose conversion factor of 4x. Importantly,
single SC doses of XP-8121 at all doses were well-tolerated and the XP-8121 doses studied were generally comparable to Synthroid 600 μg PO with respect to the safety findings. In June 2023, we
initiated  a  non-randomized,  open-label,  single  arm,  self-controlled  Phase  2  study  to  determine  a  target  dose  conversion  factor  from  stably  dosed  oral  levothyroxine  to  XP-8121  in  patients  with
hypothyroidism and also assess the safety and tolerability after once-weekly subcutaneous injections. In November 2023, the study was over 85% enrolled and should be completed in the first half of
2024.

Market Opportunity

Hypothyroidism affects approximately 20 million people in the United States. For nearly 100 years, the only available option to treat patients with hypothyroidism has been with oral levothyroxine.
The prescription category comprised of oral levothyroxine in its various branded and generic forms is the second largest prescription category in the United States with more than one hundred million
prescriptions  written  annually.  Complications  associated  with  a  requirement  to  take  medicines  by  mouth,  every  day,  are  well-documented  and  include  difficulties  in  swallowing,  gastrointestinal
malabsorption  or  intolerance,  potential  interactions  with  other  orally  administered  medications,  and  general  non-adherence  given  the  daily  regimen. Any  of  these  complications  can  contribute  to
suboptimal treatment requiring higher dosing, generally poor control over TSH levels, or complete treatment failure. We believe XP-8121 to be well-suited to address these challenges. XP-8121 is
designed to be a once-weekly, small-volume, subcutaneous injection which, given its route of administration, bypasses the gastrointestinal tract and could avoid many of the therapeutic complications
associated with the use of oral forms of levothyroxine. We believe that our novel approach to treatment has the potential to establish a new standard of care for hypothyroidism. Given the size of the
impacted patient population and the challenges faced by certain patients, we estimate the potential market opportunity for XP-8121 to be $2.0 to $3.0 billion dollars annually.

Collaboration and Partnerships

We believe that our proprietary XeriSol and XeriJect formulation capabilities could be broadly applicable for the potential development of pharmaceutical products in many therapeutic areas. To
enhance and further exploit our core formulation science, we will continue to collaborate with other pharmaceutical companies on the development of formulations of their proprietary therapeutics
with XeriSol or XeriJect. This strategy is designed to broaden our revenue stream and enhance the formulation, delivery and clinical profile of other companies’ proprietary drugs and biologics. Our
strategic goal is to ultimately enter into commercial licensing agreements with our partners upon successful completion of formulation development.

Manufacturing and Supply

We currently contract with third parties for the manufacture, assembly, testing, packaging, storage and distribution of our products. In our experience, third party contract manufacturing organizations
("CMOs")  are  generally  cost-efficient,  high  quality  and  reliable,  and  we  currently  have  no  plans  to  build  our  own  manufacturing  or  distribution  infrastructure.  Our  technical  team  has  extensive
pharmaceutical development, manufacturing, analytical, quality and distribution experience and is qualified and capable of managing supply chain operations across multiple CMOs. The standard
operating procedures and quality systems in place at Xeris and our CMOs are designed to ensure compliance with the FDA's Current Good Manufacturing Practice ("CGMP") regulations and provide
a framework for effective regulatory communications. We selected our CMOs for specific competencies, and they have met our development, manufacturing, quality and regulatory requirements and
have all been involved in manufacturing our clinical supplies, commercial registration batches, and commercial products.

Glucagon is the active pharmaceutical ingredient ("API") used in Gvoke and our ready-to-use glucagon product candidates. Bachem Americas, Inc., ("Bachem") is our primary commercial source for
glucagon  API.  Bachem  holds  a  United  States  drug  master  file  for  glucagon  produced  at  its  facility  in  Switzerland,  and  its  manufacturing  process  is  fully  validated.  We  have  entered  into  a  non-
exclusive supply agreement with Bachem. We believe that Bachem has sufficient capacity to satisfy our long-term glucagon API requirements for Gvoke and other ready-to-use glucagon product
candidates.

Manufacturing drug product for Gvoke requires an aseptic fill/finish facility capable of handling solvents and a cyclic olefinic polymer syringe. Pyramid Laboratories, Inc. ("Pyramid") has been
actively involved in the development and manufacturing of Gvoke. Its facility in California is our primary source for drug product. We have entered into a non-exclusive supply agreement with
Pyramid. We believe that Pyramid has sufficient capacity to satisfy our demand requirements for at least three to five years.

The auto-injector used to deliver drug product in Gvoke HypoPen is a proprietary multi-product device platform developed by SHL Medical AG and SHL Pharma, LLC (collectively "SHL"). SHL
produces device sub-assemblies at its facility in Taiwan and performs final drug product/device assembly operations at its facility in Florida. We have entered into a supply agreement with SHL.

We have a supply agreement with Taro Pharmaceuticals North America, Inc. ("Taro") to produce Keveyis including all packaging. If the supply agreement is terminated by Taro at the conclusion of
the renewal term, we have the right to manufacture the product on our own or have the product manufactured by a third party on our behalf.

Levoketoconazole is the API used in Recorlev. Regis Technologies, Inc. ("Regis") has been actively involved in the development and manufacturing of levoketoconazole and its facility in Illinois is
our sole source for API. We have entered into a supply agreement with Regis. We believe that Regis has sufficient capacity to satisfy our demand requirements for at least three to five years.

Manufacturing Recorlev drug product requires a conventional solid oral dosage form manufacturing facility. Lonza Tampa, LLC (f/k/a Xcelience, LLC, "Lonza") has been actively involved in the
development and manufacturing of Recorlev and its facility in Florida is our sole source for drug product. We have entered into a supply agreement with Lonza. We believe that Lonza has sufficient
capacity to satisfy our demand requirements for at least three to five years.

We believe that a number of CMOs can provide suitable secondary packaging services for Gvoke and Recorlev, and we have entered into commercial supply agreements with one vendor. A number
of third-party logistic providers can provide commercial order processing and finished goods distribution services to the United States specialty pharmacies and wholesale customers, and we have a
commercial distribution agreement with one such vendor for Gvoke, Recorlev and Keveyis.

Competition

Our  industry  is  characterized  by  intense  competition  and  a  strong  emphasis  on  proprietary  products.  While  we  believe  that  our  employees,  products,  product  candidates,  formulation  science,
development  expertise,  intellectual  property  and  scientific  knowledge  provide  us  with  competitive  advantages,  we  face  potential  competition  from  many  different  sources,  including  major
pharmaceutical, specialty pharmaceutical and biotechnology companies. Many of our potential competitors have substantially greater financial, technical and human resources than we do, as well as
more experience in the development of product candidates, obtaining FDA and other regulatory approvals of products, and the commercialization of those products.

 Gvoke:  Two  traditional  emergency  glucagon  kits  are  currently  available  to  treat  severe  hypoglycemia:  Fresenius  Kabi's  Glucagon  Emergency  Kit  and  Amphastar's  generic
Glucagon for Injection Emergency Kit. In addition to Gvoke, two ready-to-use glucagon products are currently available to treat severe hypoglycemia. The first is Amphastar's
intranasal glucagon dry powder, Baqsimi, and the second is Zealand Pharma’s dasiglucagon auto-injector, Zegalogue, which is currently commercialized by Novo Nordisk. We are
not aware of any drugs or additional treatments currently in development.

 Recorlev:  A  number  of  therapies  are  currently  approved  or  in  various  stages  of  development  for  endogenous  Cushing’s  syndrome.  Currently,  there  are  no  therapies  broadly
marketed for the treatment of endogenous Cushing’s syndrome patients in the United States. Korlym (mifepristone), marketed by Corcept Therapeutics Incorporated, is indicated to
control hyperglycemia secondary to hypercortisolism in adult patients with endogenous Cushing’s syndrome who have type 2 diabetes mellitus or glucose intolerance and have
failed surgery or are not candidates for surgery. In addition, Teva Pharmaceutical Industries Limited initiated the launch of a generic version of mifepristone in early 2024. Signifor
(pasireotide) and Signifor LAR are marketed by Recordati in the United States and are indicated for the treatment of adult patients with Cushing's disease (a subset of Cushing’s
syndrome) for whom pituitary surgery is not an option or has not been curative. Isturisa (osilodrostat), a cortisol synthesis inhibitor indicated for adult patients with Cushing’s
disease (a subset of Cushing’s syndrome) for whom pituitary surgery is not an option or has not been curative, is also marketed by Recordati. A number of products, including
ketoconazole, metyrapone, cabergoline, mitotane and etomidate are used off-label for the treatment of Cushing’s syndrome in the United States. Ketoconazole, metyrapone and
mitotane  are  marketed  by  HRA  Pharma  in  certain  European  countries.  We  are  also  facing  potential  competition  from  a  number  of  pipeline  products  in  development,  such  as
Relacorilant (CORT125134), AZD-4017 and SPI-62.

 Keveyis: In late 2022, the FDA approved a generic version of our Keveyis product, which is marketed by Torrent Pharmaceuticals Ltd. Another product, acetazolamide, an oral
carbonic anhydrase inhibitor, is used frequently off-label for the prophylactic and sometimes acute treatment of PPP. Potassium supplements are indicated for use in hypokalemic
periodic paralysis in the United States and are frequently used either chronically or for emergency treatment of episodes in the form of PPP. Several other types of drugs have been
reported to have benefits for chronic or acute use in one or more than one PPP variant, including potassium-sparing diuretics, beta receptor agonists, mexelitine and other sodium
channel blockers, and others.

Intellectual Property

Proprietary Protection

Our commercial success depends in part on our ability to obtain and maintain proprietary protection for our products and product candidates, manufacturing and process discoveries and other know-
how, to operate without infringing the proprietary rights of others, and to prevent others from infringing our proprietary rights. We have been building and continue to build our intellectual property
portfolio relating to our product candidates and formulation science. We seek to protect our proprietary position by, among other methods, filing United States and certain foreign patent applications
related to our proprietary formulation science, inventions and improvements that are important to the development and implementation of our business. We also intend to rely on trade secrets, know-
how, formulation science innovation and in-licensing opportunities to develop and maintain our proprietary position. We cannot be sure that patents will be granted with respect to any of our pending
patent applications or with respect to any patent applications filed by us in the future, nor can we be sure that any of our existing patents or any patents that may be granted to us or our partners in the
future will be commercially useful in protecting our formulation science.

Patent Rights

We currently own 170 patents issued globally, including composition of matter patents covering our ready-to-use glucagon formulation that expire in 2036. Included in the total patents, we have 60
granted  patents  globally  related  to  our  platform  technologies  and  8  patents  granted  in  the  United  States  and  listed  in  the  United  States  FDA  Orange  Book  covering  proprietary  formulations  of
levoketoconazole (the active pharmaceutical ingredient in Recorlev) and the uses of such formulations in treating certain endocrine-related diseases and syndromes. The latter includes United States
Patent Nos. 11,020,393, 11,278,547 and 11,903,940, which were granted on June 1, 2021, March 22, 2022, and February 22, 2024, respectively, and which provide patent protection through 2040 for
the use of Recorlev in the treatment of certain patients with persistent or recurrent Cushing’s syndrome.

Trade Secrets and Other Protection

In addition to patented intellectual property, we also rely on trade secrets and proprietary know-how to protect our formulation science and maintain our competitive position, especially when we do
not believe that patent protection is appropriate or can be obtained. Our policy is to require each of our employees, consultants and advisors to execute a confidentiality and inventions assignment
agreement  before  beginning  their  employment,  consulting  or  advisory  relationship  with  us.  The  agreements  generally  provide  that  the  individual  must  keep  confidential  and  not  disclose  to  other
parties any confidential information developed or learned by the individual during the course of the individual’s relationship with us except in limited circumstances. These agreements generally also
provide that we own all inventions conceived and/or reduced to practice by the individual in the course of their employment with us or rendering services to us.

Other Intellectual Property Rights

We file trademark applications and pursue registrations in the United States and abroad when appropriate. We own registered trademarks for the mark Xeris Pharmaceuticals in the United States, for
the marks GVOKE, GVOKE HYPOPEN and HYPOPEN in the United States and several ex-United States countries, the registered trademark for OGLUO in the EU and the UK, and the registered
trademarks for XERIJECT in the United States, Australia, the EU, the UK, Japan and Mexico. We also own pending trademark applications for XERISOL in the United States and a number of ex-US
countries, and for the marks GVOKE, GVOKE HYPOPEN and XERIJECT in a number of ex-United States countries, all for use in connection with our pharmaceutical research and development
and products, as well as trade names that could be used with our product candidates.

From time to time, we may find it necessary or prudent to obtain licenses from third-party intellectual property holders.

Regulation

Government Regulation

United States Drug and Biological Product Development

In the United States, the FDA regulates drugs, medical devices and combinations of drugs and devices, or combination products, under the Federal Food, Drug, and Cosmetic Act ("FDCA") and its
implementing  regulations  and  biologics  under  the  FDCA  and  the  Public  Health  Service  Act  ("PHSA")  and  their  implementing  regulations.  Drugs,  biologics,  medical  devices  and  combination
products are also subject to other federal, state and local statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local
and foreign statutes and regulations require the expenditure of substantial time and financial resources. Failure to comply with the applicable United States 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, among other actions, the FDA’s refusal to
approve pending applications, withdrawal of an approval, a clinical hold, untitled or warning letters, requests for voluntary product recalls or withdrawals from the market, product seizures, total or
partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement, or civil or criminal penalties. Any agency or judicial enforcement action
could have a material adverse effect on us.

Certain of our products and product candidates are subject to regulation as combination products, which means that they are composed of both a drug product and device product. If our drug products,
along with our combination product, marketed individually, each component would be subject to different regulatory pathways and reviewed by different centers within the FDA. A combination
product, however, is assigned to a center that will have primary jurisdiction over its regulation based on a determination of the combination product’s primary mode of action, which is the single
mode of action that provides the most important therapeutic action. In the case of Gvoke and some of our product candidates, the primary mode of action is attributable to the drug component of the
product, or biological component of the product, which means that the FDA’s Center for Drug Evaluation and Research ("CDER") or FDA’s Center for Biologics Evaluation and Research ("CBER")
has primary jurisdiction over the premarket development, review and approval of the combination product. Accordingly, we plan to continue to investigate our products through the Investigational
New Drug ("IND") framework and seek approval through the New Drug Application ("NDA") or Biologics License Applications ("BLA") pathway. Based on our discussions with the FDA to date,
we do not anticipate that the FDA will require a separate medical device authorization for the device component of our combination products, but this could change during the course of its review of
any marketing application that we may submit. The process required by the FDA before a drug or biologic may be marketed in the United States generally involves the following:























completion of extensive preclinical laboratory tests, animal studies and formulation studies in accordance with applicable regulations, including the FDA’s Good Laboratory
Practice ("GLP") regulations;
submission to the FDA of an IND, which must become effective before human clinical trials may begin;
approval by an independent institutional review board ("IRB"), representing each clinical site before each clinical trial may be initiated;
performance of adequate and well-controlled human clinical trials in accordance with an applicable IND and other clinical study related regulations, sometimes referred to as
FDA's Clinical Practices ("GCPs") regulations, to establish the safety and efficacy of the proposed drug or biologic for its proposed indication;
submission to the FDA of an NDA or BLA;
satisfactory  completion  of  an  FDA  pre-approval  inspection  of  the  manufacturing  facility  or  facilities  at  which  the  product,  or  components  thereof,  are  produced  to  assess
compliance with the FDA’s CGMP regulations;
potential FDA inspection of Xeris, the clinical trial sites, or other vendors that generated the data in support of the NDA or BLA;
payment of associated user fees;
review by an FDA advisory committee, where appropriate or if applicable;
FDA review and approval of the NDA or BLA prior to any commercial marketing or sale; and
compliance with any post-approval requirements, including the potential requirement to implement a Risk Evaluation and Mitigation Strategy ("REMS") and the potential
requirement to conduct post-approval studies.

Once  a  pharmaceutical  product  candidate  is  identified  for  development,  it  enters  the  preclinical  testing  stage.  Preclinical  tests  include  laboratory  evaluations  of  product  chemistry,  toxicity,
formulation, and stability, as well as animal studies. An IND sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data and any available clinical
data or literature, to the FDA as part of the IND. An IND is an exemption from the FDCA that allows an unapproved product to be shipped in interstate commerce for use in an investigational clinical
trial and a request for FDA authorization to administer such investigational product to humans. The sponsor must also include a protocol detailing, among other things, the objectives of the initial
clinical trial, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated if the initial clinical trial lends itself to an efficacy evaluation. Some preclinical testing may
continue even after the IND is submitted. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA raises concerns or questions related to a proposed clinical trial
and places the trial on a clinical hold within that 30-day period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. Clinical holds
also may be imposed by the FDA at any time before or during clinical trials due to safety concerns or non-compliance and may be imposed on all drug or biological products within a certain class of
drugs or biologics. The FDA also can impose partial clinical holds, for example, prohibiting the initiation of clinical trials of a certain duration or for a certain dose.

All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with GCP regulations. These regulations include the requirement that all research
subjects  provide  informed  consent  in  writing  before  their  participation  in  any  clinical  trial.  Further,  an  IRB  must  review  and  approve  the  plan  for  any  clinical  trial  before  it  commences  at  any
institution, and the IRB must conduct continuing review and reapprove the study at least annually. An IRB considers, among other things, whether the risks to individuals participating in the clinical
trial are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the information regarding the clinical trial and the consent form that must be provided to each clinical
trial subject or his or her legal representative and must monitor the clinical trial until completed.

Each new clinical protocol and any amendments to the protocol must be submitted for FDA review and to the IRBs for approval. Protocols detail, among other things, the objectives of the clinical
trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject safety.

14

Table of Contents

Human clinical trials are typically conducted in three sequential phases that may overlap or be combined: 







Phase  1.  The  product  is  initially  introduced  into  a  small  number  of  healthy  human  subjects  or  patients  and  tested  for  safety,  dosage  tolerance,  absorption,  metabolism,
distribution and excretion and, if possible, to gain early evidence on effectiveness. In the case of some products for severe or life-threatening diseases, especially when the
product is suspected or known to be unavoidably toxic, the initial human testing may be conducted in patients.
Phase 2. 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 optimal dosage and schedule.
Phase 3. Clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical trial sites.
These clinical trials are intended to establish the overall risk/benefit relationship of the product and provide an adequate basis for product labeling.

Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These studies are used to gain additional experience from the treatment of
patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of Phase 4 trials. Companies that conduct certain clinical trials are also required to register
them and post the results of completed clinical trials on a government-sponsored database, such as ClinicalTrials.gov in the United States, within certain timeframes. Failure to do so can result in
fines, adverse publicity and civil and criminal sanctions.

Progress reports detailing the results of the clinical trials, among other information, must be submitted at least annually to the FDA, and written IND safety reports must be submitted to the FDA and
the investigators for serious and unexpected adverse events, findings from other studies that suggest a significant risk to humans exposed to the product, findings from animal or in vitro testing that
suggest a significant risk to human subjects, and any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. Phase 1,
Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the clinical trial sponsor may suspend or terminate a clinical trial at any time
on various grounds, including a finding that the research subjects or patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at
its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the product has been associated with unexpected serious harm to patients. Additionally, some
clinical  trials  are  overseen  by  an  independent  group  of  qualified  experts  organized  by  the  clinical  trial  sponsor,  known  as  a  data  safety  monitoring  board  or  committee.  This  group  provides
authorization for whether a trial may move forward at designated check points based on access to certain data from the study. The clinical trial sponsor may also suspend or terminate a clinical trial
based on evolving business objectives and/or competitive climate.

Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the product and
finalize  a  process  for  manufacturing  the  product  in  commercial  quantities  in  accordance  with  CGMP  requirements.  The  manufacturing  process  must  be  capable  of  consistently  producing  quality
batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate
packaging must be selected and tested and stability studies must be conducted to demonstrate that the product candidate does not undergo unacceptable deterioration over its shelf life. In addition, for
certain combination products it may be necessary to conduct Human Factors studies prior to NDA or BLA submission to ascertain the usability of the product by patients in real-world settings.

FDA Review Process

The results of product development, preclinical studies, Human Factors studies (when required), and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on
the drug or biologic, proposed labeling and other relevant information, are submitted to the FDA as part of an NDA or BLA, requesting approval to market the product. An NDA for a new drug must
contain proof of the drug’s safety and efficacy. A BLA is a request for approval to market a biologic for one or more specified indications and must contain proof of the biologic’s safety, purity, and
potency.  Under  federal  law,  most  NDAs  or  BLAs  must  be  accompanied  by  a  significant  application  user  fee  to  the  FDA.  There  also  are  continuing  user  fee  requirements,  under  which  the  FDA
assesses  an  annual  program  fee  for  each  product  identified  in  an  approved  NDA  or  BLA.  Certain  exceptions  and  waivers  are  available  for  some  of  these  fees,  such  as  an  exception  from  the
application fee for products with orphan designation and a waiver for certain small businesses which we utilized for Gvoke.

The FDA reviews all NDAs and BLAs submitted before it accepts them for filing and may request additional information rather than accepting an NDA or BLA for filing. The FDA typically makes a
decision  on  accepting  an  NDA  or  BLA  for  filing  within  60  days  of  receipt.  The  decision  to  accept  the  NDA  or  BLA  for  filing  means  that  the  FDA  has  made  a  threshold  determination  that  the
application  is  sufficiently  complete  to  permit  a  substantive  review.  Under  the  goals  and  policies  agreed  to  by  the  FDA  under  the  Prescription  Drug  User  Fee  Act  ("PDUFA"),  the  FDA’s  goal  to
complete its substantive review and respond to the applicant is ten months from the receipt of a standard NDA or ten months from the filing date of an NDA for a new molecular entity or original
BLA. The FDA does not always meet its PDUFA goal dates, and the review process is often significantly extended by FDA requests for additional information or clarification and may go through
multiple review cycles.

After the NDA or BLA submission is accepted for filing, the FDA reviews the NDA or BLA to determine, among other things, whether the proposed product is safe and effective for its intended use,
and whether the product is being manufactured in accordance

15

Table of Contents

with CGMPs to assure and preserve the product’s identity, strength, quality, and purity. The FDA may refer applications for novel drug or biological products or drug or biological products which
present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, evaluation and a recommendation as to whether the
application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making
decisions. The FDA will likely re-analyze the clinical trial data, which could result in extensive discussions between the FDA and us during the review process. The review and evaluation of an NDA
or BLA by the FDA is extensive and time consuming and may take longer than originally planned to complete, and we may not receive a timely approval, if at all.

Before approving an NDA or BLA, the FDA may conduct a pre-approval inspection of the manufacturing facilities for the new product to determine whether they comply with CGMPs. The FDA will
not approve the product 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. In addition, before approving an NDA or BLA, the FDA may also audit data from clinical trials to ensure compliance with GCP requirements. After the FDA evaluates
the application, manufacturing process, and manufacturing facilities, it may issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug or
biologic  with  specific  prescribing  information  for  specific  indications.  A  Complete  Response  Letter  indicates  that  the  review  cycle  of  the  application  is  complete  and  the  application  will  not  be
approved in its present form. A Complete Response Letter usually describes all the specific deficiencies in the NDA or BLA identified by the FDA. The Complete Response Letter may require
additional clinical data and/or an additional pivotal Phase 3 clinical trial(s), and/or other significant and time-consuming requirements related to clinical trials, nonclinical studies, or manufacturing. If
a Complete Response Letter is issued, the applicant may either resubmit the NDA or BLA, addressing all the deficiencies identified in the letter, or withdraw the application. Even if such data and
information are submitted, the FDA may ultimately decide that the NDA or BLA does not satisfy the criteria for approval. Data obtained from clinical trials are not always conclusive, and the FDA
may interpret data differently than we interpret the same data.

There is no assurance that the FDA will ultimately approve a product for marketing in the United States, and we may encounter significant difficulties or costs during the review process. If a product
receives marketing approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value
of the product. Further, the FDA may require that certain contraindications, warnings, or precautions be included in the product labeling or may condition the approval of the NDA or BLA on other
changes to the proposed labeling, development of adequate controls and specifications, or a commitment to conduct post-market testing or clinical trials and surveillance to monitor the effects of
approved products. For example, the FDA may require Phase 4 clinical trials to further assess drug safety and effectiveness and may require testing and surveillance programs to monitor the safety of
approved  products  that  have  been  commercialized.  The  FDA  may  also  place  other  conditions  on  approvals  including  the  requirement  for  a  REMS  to  assure  the  safe  use  of  the  drug.  If  the  FDA
concludes  a  REMS  is  needed,  the  sponsor  of  the  NDA  must  submit  a  proposed  REMS;  the  FDA  will  not  approve  the  NDA  without  an  approved  REMS,  if  required.  A  REMS  could  include
medication  guides,  physician  communication  plans,  or  elements  to  assure  safe  use,  such  as  restricted  distribution  methods,  patient  registries,  and  other  risk  minimization  tools.  Any  of  these
limitations on approval or marketing could restrict the commercial promotion, distribution, prescription, or dispensing of products. Product approvals may be withdrawn for non-compliance with
regulatory requirements or if problems occur following initial marketing.

Section 505(b)(2) NDAs

NDAs for most new drug products are based on at least two adequate and well-controlled clinical studies and must contain substantial evidence of the safety and effectiveness of the proposed new
product for the proposed use. These applications are submitted under Section 505(b)(1) of the FDCA. The FDA is authorized, however, to approve an alternative type of NDA under Section 505(b)(2)
of  the  FDCA.  This  type  of  application  allows  the  applicant  to  rely,  in  part,  on  the  FDA’s  previous  findings  of  safety  and  effectiveness  for  a  similar  product,  or  published  literature.  Specifically,
Section 505(b)(2) applies to NDAs for a drug for which the investigations relied upon by the applicant for approval of the application "were not conducted by or for the applicant and for which the
applicant has not obtained a right of reference or use from the person by or for whom the investigations were conducted."

Thus, Section 505(b)(2) authorizes the FDA to approve an NDA based on safety and effectiveness data that were not developed by the applicant. NDAs filed under Section 505(b)(2) may provide an
alternative and potentially more expeditious pathway to FDA approval for new or improved formulations or new uses of previously approved products. If the 505(b)(2) applicant can establish that
reliance on the FDA’s previous approval is scientifically appropriate, the applicant may eliminate the need to conduct certain preclinical or clinical studies of the new product. The FDA may also
require companies to perform additional studies or measurements to support the change from the approved product. The FDA may then approve the new drug candidate for all or some of the labeled
indications for which the referenced product has been approved, as well as for any new indication sought by the Section 505(b)(2) applicant.

Abbreviated New Drug Applications for Generic Drugs

In 1984, with passage of the Hatch-Waxman Amendments to the FDCA, Congress established an abbreviated regulatory scheme authorizing the FDA to approve generic drugs that are shown to
contain  the  same  active  ingredients  as,  and  to  be  bioequivalent  to,  drugs  previously  approved  by  the  FDA  pursuant  to  NDAs.  To  obtain  approval  of  a  generic  drug,  an  applicant  must  submit  an
abbreviated new drug application ("ANDA") to the agency. An ANDA is a comprehensive submission that contains, among other things, data and information pertaining to the active pharmaceutical
ingredient, bioequivalence, drug product formulation,

16

Table of Contents

specifications and stability of the generic drug, as well as analytical methods, manufacturing process validation data and quality control procedures. ANDAs are "abbreviated" because they generally
do not include preclinical and clinical data to demonstrate safety and effectiveness. Instead, in support of such applications, a generic manufacturer may rely on the preclinical and clinical testing
previously conducted for a drug product previously approved under an NDA, known as the reference-listed drug ("RLD").

Specifically, in order for an ANDA to be approved, the FDA must find that the generic version is the same as the RLD with respect to the active ingredients, the route of administration, the dosage
form, the strength of the drug and the conditions of use of the drug. At the same time, the FDA must also determine that the generic drug is "bioequivalent" to the innovator drug. Under the statute, a
generic drug is bioequivalent to an RLD if the rate and extent of absorption of the drug do not show a significant difference from the rate and extent of absorption of the RLD. Upon approval of an
ANDA,  the  FDA  indicates  whether  the  generic  product  is  "therapeutically  equivalent"  to  the  RLD  in  its  publication  "Approved  Drug  Products  with  Therapeutic  Equivalence  Evaluations,"  also
referred to as the "Orange Book." Physicians and pharmacists consider a therapeutic equivalent generic drug to be fully substitutable for the RLD. In addition, by operation of certain state laws and
numerous health insurance programs, the FDA’s designation of therapeutic equivalence often results in substitution of the generic drug without the knowledge or consent of either the prescribing
physician or patient.

Under the Hatch-Waxman Amendments, the FDA may not approve an ANDA until any applicable period of non-patent exclusivity for the RLD has expired. The FDCA provides a period of five
years of non-patent data exclusivity for a new drug containing a new chemical entity. For the purposes of this provision, a new chemical entity ("NCE") is a drug that contains no active moiety, which
is the molecule or ion responsible for the physiological or pharmacological action of the drug substance, that has previously been approved by the FDA in any other NDA. In cases where such NCE
exclusivity has been granted, an ANDA may not be filed with the FDA until the expiration of five years unless the submission is accompanied by a Paragraph IV certification, which states that the
proposed  drug  will  not  infringe  the  already  approved  product’s  listed  patents  or  that  such  patents  are  invalid  or  unenforceable,  in  which  case  the  applicant  may  submit  its  application  four  years
following the original product approval.

The FDCA also provides for a period of three years of exclusivity if the NDA includes reports of one or more new clinical investigations, other than bioavailability or bioequivalence studies, that
were conducted by or for the applicant and are essential to the approval of the application. This three-year exclusivity period often protects changes to a previously approved drug product, such as a
new dosage form, route of administration, combination or indication. Three-year exclusivity would be available for a drug product that contains a previously approved active moiety, provided the
statutory  requirement  for  a  new  clinical  investigation  is  satisfied.  Unlike  five-year  NCE  exclusivity,  an  award  of  three-year  exclusivity  does  not  block  the  FDA  from  accepting  ANDAs  seeking
approval for generic versions of the drug as of the date of approval of the original drug product. The FDA typically makes decisions about awards of data exclusivity shortly before a product is
approved.

Marketing Exclusivity for Biological Products

An  abbreviated  approval  pathway  for  biological  products  shown  to  be  biosimilar  to  or  interchangeable  with  an  FDA-licensed  reference  biological  product  was  created  by  the  Biologics  Price
Competition and Innovation Act of 2009 ("BPCI Act"). This amendment to the PHSA, in part, attempts to minimize duplicative testing. Biosimilarity, which requires that the biological product be
highly  similar  to  the  reference  product  notwithstanding  minor  differences  in  clinically  inactive  components  and  that  there  be  no  clinically  meaningful  differences  between  the  product  and  the
reference product in terms of safety, purity, and potency, can be shown through analytical studies, animal studies, and a clinical trial or trials. Interchangeability requires that a biological product be
biosimilar to the reference product and that the product can be expected to produce the same clinical results as the reference product in any given patient and, for products administered multiple times
to an individual, that the product and the reference product may be alternated or switched after one has been previously administered without increasing safety risks or risks of diminished efficacy
relative to exclusive use of the reference biological product without such alternation or switch.

A reference biological product is granted 12 years of data exclusivity from the time of first licensure of the product, and the FDA will not accept an application for a biosimilar or interchangeable
product based on the reference biological product until four years after the date of first licensure of the reference product. ‘‘First licensure’’ typically means the initial date the particular product at
issue was licensed in the United States. Date of first licensure does not include the date of licensure of (and a new period of exclusivity is not available for) a biological product if the licensure is for a
supplement for the biological product or for a subsequent application by the same sponsor or manufacturer of the biological product (or licensor, predecessor in interest, or other related entity) for a
change (not including a modification to the structure of the biological product) that results in a new indication, route of administration, dosing schedule, dosage form, delivery system, delivery device
or strength, or for a modification to the structure of the biological product that does not result in a change in safety, purity, or potency.

Hatch-Waxman Patent Certification and the 30-Month Stay

Upon approval of an NDA, including a 505(b)(2) NDA, or a supplement thereto, NDA sponsors are required to list with the FDA each patent with claims that cover the applicant’s product or an
approved method of using the product. Each of the patents listed by the NDA sponsor is published in the Orange Book. When an ANDA applicant files its application with the FDA, the applicant is
required to certify to the FDA concerning any patents listed for the reference product in the Orange Book, except for patents covering methods of use for which the ANDA applicant is not seeking
approval. To the extent that the Section 505(b)(2) applicant relies on studies

17

Table of Contents

conducted for an already approved product, the applicant is required to certify to the FDA concerning any patents listed for the approved product in the Orange Book to the same extent that an ANDA
applicant would.

Specifically, the applicant must certify with respect to each patent that:

  






the required patent information has not been filed;
the listed patent has expired;
the listed patent has not expired, but will expire on a particular date and approval is sought after patent expiration; or
the listed patent is invalid, unenforceable or will not be infringed by the new product.

A  certification  that  the  new  product  will  not  infringe  the  already  approved  product’s  listed  patents  or  that  such  patents  are  invalid  or  unenforceable  is  called  a  Paragraph  IV  certification.  If  the
applicant does not provide a Paragraph IV certification against the listed patents or indicates that it is not seeking approval of a patented method of use, the application will not be approved until all
the listed patents claiming the referenced product have expired (other than method of use patents involving indications for which the applicant is not seeking approval).

If the ANDA or 505(b)(2) applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA and patent holders once the
ANDA or the 505(b)(2) application has been accepted for filing by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV
certification.  The  filing  of  a  patent  infringement  lawsuit  within  45  days  after  the  receipt  of  a  Paragraph  IV  certification  automatically  prevents  the  FDA  from  approving  the  ANDA  or  505(b)(2)
application until the earlier of 30 months after the receipt of the Paragraph IV notice, expiration of the patent, or a decision in the infringement case that is favorable to the applicant. The ANDA or
505(b)(2) application also will not be approved until any applicable non-patent exclusivity listed in the Orange Book for the branded reference drug has expired.

Regulation of Combination Products in the United States

Certain products may be comprised of components, such as drug components and device components, that would normally be regulated under different types of regulatory authorities, and frequently
by different centers at the FDA. These products are known as combination products. Specifically, under regulations issued by the FDA, a combination product may be:

  






a product comprised of two or more regulated components that are physically, chemically, or otherwise combined or mixed and produced as a single entity;
two or more separate products packaged together in a single package or as a unit and comprised of drug and device products, device and biological products, or biological and
drug products;
a drug, device, or biological product packaged separately that according to its investigational plan or proposed labeling is intended for use only with an approved individually
specified drug, or device, or biological product where both are required to achieve the intended use, indication, or effect and where upon approval of the proposed product the
labeling of the approved product would need to be changed, e.g., to reflect a change in intended use, dosage form, strength, route of administration, or significant change in
dose; or
any  investigational  drug,  device,  or  biological  product  packaged  separately  that  according  to  its  proposed  labeling  is  for  use  only  with  another  individually  specified
investigational drug, device, or biological product where both are required to achieve the intended use, indication, or effect.

Under the FDCA and its implementing regulations, the FDA is charged with assigning a center with primary jurisdiction, or a lead center, for review of a combination product. The designation of a
lead center generally eliminates the need to receive approvals from more than one FDA component for combination products, although it does not preclude consultations by the lead center with other
components of the FDA. The determination of which center will be the lead center is based on the "primary mode of action" of the combination product. Thus, if the primary mode of action of a drug-
device combination product is attributable to the drug product, the FDA center responsible for premarket review of the drug product would have primary jurisdiction for the combination product. The
FDA also has established an Office of Combination Products to address issues surrounding combination products and provide more certainty to the regulatory review process. That office serves as a
focal point for combination product issues for agency reviewers and industry. It is also responsible for developing guidance and regulations to clarify the regulation of combination products and for
assignment of the FDA center that has primary jurisdiction for review of combination products where the jurisdiction is unclear or in dispute.

A combination product with a drug primary mode of action generally would be reviewed and approved pursuant to the drug approval processes under the FDCA. In reviewing the NDA or 505(b)(2)
application for such a product, however, FDA reviewers in the drug center could consult with their counterparts in the device center to ensure that the device component of the combination product
met applicable requirements regarding safety, effectiveness, durability and performance. In addition, under FDA regulations, combination products are subject to CGMP requirements applicable to
both drugs and devices, including the Quality System ("QS") regulations applicable to medical devices.

18

 
 
Table of Contents

Drug-device combination products present unique challenges for competitors seeking approval of an ANDA for generic versions of combination products. Generally, the FDA reviews both the drug
and  device  constituents  of  a  proposed  generic  product  to  determine  whether  it  is  the  same  as  the  innovator  product,  including  whether  the  basic  design  and  operating  principles  of  the  device
component are the same and whether minor differences require significant differences in labeling for safe and effective use. If FDA determines that the device component of the proposed generic
product is not the same in terms of performance and critical design, or that the labeling is not the same, it generally will not approve the ANDA. Likewise, if the FDA determines that certain clinical
studies, such as clinical usability or human factors studies, are necessary to demonstrate the safety and/or effectiveness of the device component, the FDA generally will not accept or approve an
ANDA for a combination product and will instead require the submission of a full NDA or 505(b)(2) application.

Post-Marketing Requirements

Any products for which we receive FDA approval are subject to continuing regulation by the FDA, including, among other things, monitoring and recordkeeping activities, reporting to the applicable
regulatory  authorities  of  adverse  events  with  the  product,  providing  the  applicable  regulatory  authorities  with  updated  safety  and  efficacy  information,  and  product  sampling  and  distribution
requirements in accordance with the Prescription Drug Marketing Act ("PDMA"), a part of the FDCA, as well as the Drug Supply Chain Security Act ("DSCSA"). The PDMA, its implementing
regulations and state laws limit the distribution of prescription pharmaceutical product samples, and the DSCSA imposes requirements to ensure accountability in distribution and to identify and
remove counterfeit and other illegitimate products from the market. Moreover, each component of a combination product retains its regulatory status (as a drug or device, for example) and is subject
to the requirements established by the FDA for that type of component. The FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the
market.

Prescription  drug  and  biologic  advertising  is  subject  to  federal,  state  and  foreign  regulations.  In  the  United  States,  the  FDA  regulates  prescription  drug  and  biologic  promotion  and  advertising,
including  direct-to-consumer  advertising.  Prescription  drug  and  biologic  promotional  materials  must  be  submitted  to  the  FDA  in  conjunction  with  their  first  use.  In  addition,  a  pharmaceutical
company must comply with restrictions on promoting drugs and biologics for uses or in patient populations that are not described in the drug’s or biologic's approved labeling (known as "off-label
use"), limitations on industry-sponsored scientific and educational activities, and requirements for promotional activities involving the internet. Although physicians may prescribe legally available
drugs or biologics for off-label uses, manufacturers are prohibited from marketing or promoting such off-label uses.

In  the  United  States,  once  a  product  is  approved,  its  manufacture  is  subject  to  comprehensive  and  continuing  regulation  by  the  FDA.  The  FDA  regulations  require  that  combination  products  be
manufactured in specific approved facilities and in accordance with CGMPs applicable to drugs, biologics and devices, including certain QS requirements. We rely, and expect to continue to rely, on
third parties for the production of clinical and commercial quantities of our products in accordance with CGMP regulations. CGMP regulations require among other things, quality control and quality
assurance as well as the corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from CGMP. Drug and biologics manufacturers and
other  entities  involved  in  the  manufacture  and  distribution  of  approved  drugs  or  biologics  are  required  to  register  their  establishments  with  the  FDA  and  certain  state  agencies  and  are  subject  to
periodic unannounced inspections by the FDA and certain state agencies for compliance with CGMPs and other laws. Accordingly, manufacturers must continue to expend time, money, and effort in
the  area  of  production  and  quality  control  to  maintain  CGMP  compliance.  These  regulations  also  impose  certain  organizational,  procedural  and  documentation  requirements  with  respect  to
manufacturing and quality assurance activities. NDA or BLA holders using contract manufacturers, laboratories or packagers are responsible for the selection and monitoring of qualified firms, and,
in  certain  circumstances,  qualified  suppliers  to  these  firms.  These  firms  and,  where  applicable,  their  suppliers  are  subject  to  inspections  by  the  FDA  at  any  time,  and  the  discovery  of  violative
conditions, including failure to conform to CGMPs, could result in enforcement actions that interrupt the operation of any such facilities or the ability to distribute products manufactured, processed
or tested by them. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved NDA or BLA, including, among other things,
recall or withdrawal of the product from the market.

The FDA also may require post-marketing testing, known as Phase 4 testing or REMS and surveillance to monitor the effects of an approved product or place conditions on an approval that could
restrict the distribution or use of the product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences,
including adverse publicity, judicial or administrative enforcement, untitled or warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal
penalties,  among  others.  Newly  discovered  or  developed  safety  or  effectiveness  data  may  require  changes  to  a  product’s  approved  labeling,  including  the  addition  of  new  warnings  and
contraindications, and may require the implementation of other risk management measures. Also, new government requirements, including those resulting from new legislation, may be established, or
the FDA’s policies may change, which could delay or prevent regulatory approval of our products under development and impact approved products already on the market.

Other Regulatory Matters

The distribution of pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent
the unauthorized sale of pharmaceutical products.

19

Table of Contents

The failure to comply with regulatory requirements subjects firms to possible legal or regulatory action. Depending on the circumstances, failure to meet applicable regulatory requirements can result
in criminal prosecution, fines or other penalties, injunctions, voluntary recall, seizure of products, total or partial suspension of production, denial or withdrawal of product approvals, exclusion from
federal healthcare programs, or refusal to allow a firm to enter into supply contracts, including government contracts. In addition, even if a firm complies with FDA and other requirements, new
information  regarding  the  safety  or  effectiveness  of  a  product  could  lead  the  FDA  to  modify  or  withdraw  product  approval.  Prohibitions  or  restrictions  on  sales  or  withdrawal  of  future  products
marketed by us could materially affect our business in an adverse way.

Changes  in  regulations,  statutes  or  the  interpretation  of  existing  regulations  could  impact  our  business  in  the  future  by  requiring,  for  example:  (i)  changes  to  our  manufacturing  arrangements;
(ii) additions or modifications to product labeling; (iii) the voluntary recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were to be imposed,
they could adversely affect the operation of our business.

Orphan Designation and Exclusivity

The  FDA  may  grant  orphan  drug  designation  to  drugs  intended  to  treat  a  rare  disease  or  condition  that  affects  fewer  than  200,000  individuals  in  the  United  States.  Alternatively,  orphan  drug
designation may be available if the disease or the condition affects more than 200,000 individuals in the United States and there is no reasonable expectation that the cost of developing and making
the drug for this type of disease or condition will be recovered from sales in the United States.

Orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-fee waivers. If a product with orphan
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 generally will 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 condition for seven years, except in certain limited circumstances. Orphan exclusivity does not block the approval of a different drug for the same rare disease or condition, nor does it block
the approval of the same drug for different conditions. If a drug 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.

Orphan drug exclusivity will not bar approval of another product with the same drug for the same condition under certain circumstances, including if a subsequent product with the same drug for the
same condition is shown to be clinically superior to the approved product on the basis of greater efficacy or safety, or providing a major contribution to patient care, or if the company with orphan
drug exclusivity cannot assure the availability of sufficient quantities of the drug to meet the needs of persons with the disease or condition for which the drug was designated.

Pediatric Studies and Exclusivity

Under the Pediatric Research Equity Act of 2003, as amended, an NDA or supplement thereto must contain data to assess the safety and effectiveness of the product for the claimed indications in all
relevant  pediatric  subpopulations,  and  to  support  dosing  and  administration  for  each  pediatric  subpopulation  for  which  the  product  is  safe  and  effective.  A  sponsor  who  is  planning  to  submit  a
marketing application for a drug product that includes a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration must submit an initial Pediatric
Study Plan ("PSP") within sixty days of an end-of-Phase 2 meeting or as may be agreed between the sponsor and the FDA. The initial PSP must include an outline of the pediatric study or studies that
the sponsor plans to conduct, including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not including such detailed information, and any
request  for  a  deferral  of  pediatric  assessments  or  a  full  or  partial  waiver  of  the  requirement  to  provide  data  from  pediatric  studies  along  with  supporting  information.  The  FDA  may,  on  its  own
initiative or at the request of the applicant, grant deferrals for submission of some or all pediatric data until after approval of the product for use in adults or full or partial waivers if certain criteria are
met. The FDA and the sponsor must reach agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to the pediatric plan need to be considered
based  on  data  collected  from  preclinical  studies,  early  phase  clinical  trials,  and/or  other  clinical  development  programs.  The  requirements  for  pediatric  data  generally  do  not  apply  to  drugs  or
biologics for an indication for which orphan designation has been granted.

A biological product or drug can obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods for all formulations, dosage
forms, and indications of the active moiety and, for drugs, patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection and, for drugs, patent term, may be granted
based on the voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for such a study, provided that at the time pediatric exclusivity is granted there is not less
than nine months of term remaining.

Expedited Review and Approval Programs

A  sponsor  may  seek  approval  of  its  product  candidate  under  programs  designed  to  accelerate  the  FDA’s  review  and  approval  of  new  drugs  and  biological  products  that  meet  certain  criteria.
Specifically, new drugs and biological products are eligible for Fast Track designation if they are intended to treat a serious or life-threatening disease or condition and demonstrate the potential to
address

20

Table of Contents

unmet medical needs for that disease or condition. For a Fast Track product, the FDA may consider sections of the NDA or BLA for review on a rolling basis before the complete application is
submitted if relevant criteria are met.

A product candidate may also qualify for priority review, under which the FDA generally sets the target date for FDA action on the NDA or BLA that is subject to PDUFA goals at six months after
the FDA accepts the application for filing, or for drugs that are not new chemical entities, six months after the FDA receives the application. Priority review is granted when there is evidence that the
proposed product would be a significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of a serious condition. If criteria are not met for priority review, the
application is subject to the standard FDA PDUFA review period of ten months after the FDA accepts the application for filing, or for drugs that are not new chemical entities, ten months after FDA
receives the application. Priority review designation does not change the scientific or medical standard for approval or the quality of evidence necessary to support approval.

Under the accelerated approval program, the FDA may approve an NDA or BLA on the basis of either 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. Post-marketing studies or completion of ongoing studies after regulatory approvals are generally
required to verify the drug or biologic’s clinical benefit in relationship to the surrogate endpoint or ultimate outcome in relationship to the clinical benefit. Under the Food and Drug Omnibus Reform
Act of 2022, ("FDORA"), the FDA is now permitted to require, as appropriate, that such trials be underway prior to approval or within a specific time period after the date of approval for a product
granted accelerated approval. Sponsors are also required to send updates to the FDA every 180 days on the status of such studies, including progress toward enrollment targets, and the FDA must
promptly post this information publicly. Under FDORA, the FDA has increased authority for expedited procedures to withdraw approval of a drug or indication approved under accelerated approval
if, for example, the sponsor fails to conduct such studies in a timely manner and send the necessary updates to the FDA, or if a confirmatory trial fails to verify the predicted clinical benefit of the
product.

The FDA also may designate a product candidate as a Breakthrough Therapy if it is intended, either alone or in combination with one or more other products, to treat a serious or life-threatening
disease or condition and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such
as substantial treatment effects observed early in clinical development. Breakthrough Therapy designation includes all of the Fast Track program features, as well as more intensive FDA interaction
and guidance. The Breakthrough Therapy designation is a distinct status from both accelerated approval and priority review, which also can be granted to the same drug or biologic if relevant criteria
are met. If a product is designated as Breakthrough Therapy, the FDA will work to expedite the development and review of such product.

Fast Track designation, Breakthrough Therapy designation and priority review do not change the standards for approval but may expedite the development or approval process. Even if a product
qualifies for one or more of these programs, the FDA may later decide that the product no longer meets the conditions for qualification or decide that the time period for FDA review or approval will
not be shortened.

Regulations and Procedures Governing Approval of Medicinal Products in the European Union

In order to market any product outside the United States, a company must also comply with numerous and varying regulatory requirements of other countries and jurisdictions regarding quality,
safety, and efficacy and governing, among other things, clinical trials, marketing authorization, pricing, commercial sales and distribution of products. Whether or not it obtains FDA approval for a
product, an applicant will need to obtain the necessary approvals by the comparable non-United States regulatory authorities before it can commence clinical trials or marketing of the product in those
countries or jurisdictions. Specifically, the process governing approval of medicinal products in the EU generally follows the same lines as in the United States. It entails satisfactory completion of
pharmaceutical development, pre-clinical studies, and adequate and well-controlled clinical trials to establish the safety and efficacy of the medicinal product for each proposed indication. It also
requires  the  submission  to  the  relevant  competent  authorities  for  clinical  trials  authorization  and  to  such  competent  authorities  or  the  European  Medicines  Agency  ("EMA")  of  a  marketing
authorisation application ("MAA") and granting of a marketing authorization before the product can be marketed and sold in the EU. Similar requirements are necessary to conduct clinical trials in
the United Kingdom, with the submission of an MAA to the Medicines and Healthcare Products Regulatory Agency ("MHRA"), the UK medicines regulator for marketing authorization.

Clinical Trial Approval

In April 2014, the EU adopted the Clinical Trials Regulation (EU) No 536/2014 ("CTR"), which replaced the previous Clinical Trials Directive. The CTR entered into application on January 31,
2022. The transitory provisions of the CTR provide that, by January 31, 2025, all ongoing clinical trials must have transitioned to the CTR. The CTR overhauled the system of approvals for clinical
trials in the EU. Specifically, the new legislation, which is directly applicable in all EU Member States (meaning no national implementing legislation in each Member State is required), aims at
simplifying and streamlining the approval of clinical trials in the EU, simplifying adverse-event reporting procedures, improving the supervision of clinical trials and increasing their transparency. For
instance, the CTR provides for a streamlined application procedure via a single-entry point (through the Clinical Trials Information System ("CTIS")) and strictly defined deadlines for the assessment
of clinical trial applications. Parties conducting certain clinical trials must, as in the United States, post clinical trial information in the EU through the CTIS.

21

Table of Contents

Marketing Authorization

To obtain a marketing authorization for a product in the EU, an applicant must submit an MAA either under a centralized procedure administered by the EMA, or one of the procedures administered
by  competent  authorities  in  the  EU  Member  States  (decentralized  procedure,  national  procedure  or  mutual  recognition  procedure).  The  centralized  procedure  provides  for  the  grant  of  a  single
marketing authorization by the European Commission that is valid throughout the EU, and in the additional Member States of the European Economic Area ("EEA") (i.e. Iceland, Liechtenstein and
Norway). Pursuant to Regulation (EC) No 726/2004, the centralized procedure is compulsory for specific products, including for medicines produced by certain biotechnological processes, products
designated  as  orphan  medicinal  products,  advanced  therapy  medicinal  products  (gene-therapy,  somatic  cell-therapy  or  tissue-engineered  medicines),  and  products  with  a  new  active  substance
indicated for the treatment of HIV, AIDS, cancer, neurodegenerative disorders, diabetes, auto-immune and other immune dysfunctions, and viral diseases. The centralized procedure is optional for
products containing a new active substance not yet authorized in the EU, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the interest of public
health in the EU.

National marketing authorizations, which are issued by the competent authorities of the Member States of the EU and only cover their respective territory, are available for products not falling within
the mandatory scope of the centralized procedure. Where a product has already been authorized for marketing in a Member State of the EU, this national authorization can be recognized in other
Member States through the mutual recognition procedure. If the product has not received a national authorization in any Member State at the time of application, it can be approved simultaneously in
various Member States through the decentralized procedure.

Now that the UK has left the EU, Great Britain is no longer covered by centralized marketing authorizations (under the Northern Ireland Protocol, centralized marketing authorizations currently
continue to be recognized in Northern Ireland). A separate marketing authorization is therefore required to market products in Great Britain. On January 1, 2024, a new international recognition
framework was put in place by the MHRA, under which the MHRA may have regard to decisions on the approval of marketing authorizations made by the EMA and certain other regulators when
determining  an  application  for  a  new  Great  Britain  marketing  authorization.  The  MHRA  also  has  the  power  to  have  regard  to  marketing  authorizations  approved  in  EU  Member  States  through
decentralized or mutual recognition procedures with a view to more quickly granting a marketing authorization in the UK or Great Britain.

Data and Market Exclusivity

In the EU, innovative medicinal products approved on the basis of a complete and independent data package qualify for eight years of data exclusivity upon marketing authorization and an additional
two years of market exclusivity. Data exclusivity, if granted, prevents applicants for authorization of generics or biosimilars of these innovative products from referencing the innovator’s pre-clinical
and clinical trial data contained in the dossier of the reference product when applying for a generic or biosimilar marketing authorization in the EU, during a period of eight years from the date on
which  the  reference  product  was  first  authorized  in  the  EU.  During  an  additional  two-year  period  of  market  exclusivity,  a  generic  or  biosimilar  MAA  can  be  submitted  and  authorized,  and  the
innovator’s data may be referenced, but no generic or biosimilar medicinal product can be placed on the EU market until the expiration of the market exclusivity. The overall ten-year period will be
extended to a maximum of 11 years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which,
during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. There is no guarantee that a product will be considered
by the EMA to be an innovative medicinal product, and products may not qualify for data exclusivity. Even if a product is considered to be an innovative medicinal product so that the innovator gains
the prescribed period of data exclusivity, another company nevertheless could also market another version of the product if such company obtained a marketing authorization based on an MAA with a
complete and independent data package of pharmaceutical tests, preclinical tests and clinical trials.

Periods of Authorization and Renewals

A marketing authorization has an initial validity for five years in principle. The marketing authorization may be renewed after five years on the basis of a re-evaluation of the risk-benefit balance by
the EMA (for a centrally authorized product) or by the competent authority of the relevant EU Member State (for a nationally authorized product). To this end, the marketing authorization holder
must provide the EMA or the competent authority with a consolidated version of the file in respect of quality, safety and efficacy, including all variations introduced since the marketing authorization
was granted, at least nine months before the marketing authorization ceases to be valid. The European Commission or the competent authorities of the EU Member States may decide, on justified
grounds relating to pharmacovigilance, to proceed with one further five-year period of marketing authorization. Once subsequently definitively renewed, the marketing authorization shall be valid for
an  unlimited  period.  Any  authorization  which  is  not  followed  by  the  actual  placing  of  the  medicinal  product  on  the  EU  market  (in  respect  of  the  centralized  procedure)  or  on  the  market  of  the
authorizing EU Member State (for a nationally authorized product) within three years after authorization, or if the product is removed from the market for three consecutive years, ceases to be valid
(the so-called sunset clause).

Regulatory Requirements After a Marketing Authorization has been Obtained

Where an authorization for a medicinal product in the EU is obtained, the holder of the marketing authorization is required to comply with a range of requirements applicable to the manufacturing,
marketing, promotion and sale of medicinal products. These include:

22

Table of Contents

  





Compliance  with  the  EU’s  stringent  pharmacovigilance  or  safety  reporting  rules  must  be  ensured.  These  rules  can  impose  post-authorization  studies  and  additional
monitoring obligations.

The  manufacturing  of  authorized  medicinal  products,  for  which  a  separate  manufacturer’s  license  is  mandatory,  must  also  be  conducted  in  strict  compliance  with  the
applicable  EU  laws,  regulations  and  guidance,  including  Directive  2001/83/EC,  Directive  (EU)  2017/1572,  Regulation  (EC)  No  726/2004  and  the  European  Commission
Guidelines  for  Good  Manufacturing  Practice.  These  requirements  include  compliance  with  EU  cGMP  standards  when  manufacturing  medicinal  products  and  active
pharmaceutical  ingredients,  including  the  manufacture  of  active  pharmaceutical  ingredients  outside  of  the  EU  with  the  intention  to  import  the  active  pharmaceutical
ingredients into the EU.

The marketing and promotion of authorized medicinal products, including industry-sponsored continuing medical education and advertising directed toward the prescribers of
medicinal products and/or the general public, are strictly regulated in the EU notably under Directive 2001/83/EC, as amended, and are also subject to EU Member State
national laws. Direct-to-consumer advertising of prescription medicines is prohibited across the EU.

The aforementioned EU rules are generally applicable in the EEA.

Reform of the Regulatory Framework in the European Union

The European Commission introduced legislative proposals in April 2023 that, if implemented, will replace the current regulatory framework in the EU for all medicines (including those for rare
diseases and for children). The European Commission has provided the legislative proposals to the European Parliament and the European Council for their review and approval. In October 2023, the
European  Parliament  published  draft  reports  proposing  amendments  to  the  legislative  proposals,  which  will  be  debated  by  the  European  Parliament.  Once  the  European  Commission’s  legislative
proposals are approved (with or without amendment), they will be adopted into EU law.

Other Healthcare Laws and Compliance Requirements

In addition to FDA restrictions on the marketing of pharmaceutical products and medical devices, we may be subject to various federal and state laws targeting fraud and abuse in the healthcare
industry. Although we do not provide healthcare services, submit claims for third-party reimbursement, or receive payments directly from Medicare, Medicaid or other third-party payors for our
products, we are subject to broadly applicable healthcare fraud and abuse regulation and enforcement by federal and state governments, which could significantly impact our business. Manufacturing,
sales, promotion and other activities following product approval are also subject to regulation by numerous regulatory authorities in the United States in addition to the FDA, including the Centers for
Medicare  &  Medicaid  Services  ("CMS"),  other  divisions  of  the  Department  of  Health  and  Human  Services  ("HHS"),  the  Department  of  Justice  ("DOJ"),  the  Drug  Enforcement  Administration
("DEA"), the Consumer Product Safety Commission ("CPSC"), the Federal Trade Commission ("FTC"), the Occupational Safety & Health Administration ("OSHA"), the Environmental Protection
Agency ("EPA"), and state and local governments. These laws may impact, among other things, our proposed sales, marketing and education programs. In addition, we may be subject to patient
privacy regulation by the federal government and the states in which we conduct our business as well as in foreign jurisdictions in which we may conduct trials or where we may otherwise be subject
to local regulation. The laws that may affect our ability to operate include:

  

Anti-Kickback  Statute  ("AKS"). The  federal  AKS  makes  it  illegal  for  any  person  or  entity  (including  a  prescription  drug  manufacturer  or  a  party  acting  on  its  behalf)  to
knowingly and willfully solicit, offer, receive or pay remuneration, directly or indirectly, in cash or in kind, in exchange for or intended to induce or reward either the referral
of an individual for, or the purchase, order, prescription or recommendation or arranging of, any good or service, for which payment may be made under a federal healthcare
program such as Medicare and Medicaid. This statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on the one hand and prescribers,
purchasers  and  formulary  managers  on  the  other.  Although  there  are  several  statutory  exceptions  and  regulatory  safe  harbors  protecting  certain  common  activities  from
prosecution, they are drawn narrowly, and practices that involve remuneration intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they
do not qualify for an exception or safe harbor. A person or entity can be found guilty of violating the AKS without actual knowledge of the statute or specific intent to violate
it. In addition, the government may assert that a claim including items or services resulting from a violation of the AKS constitutes a false or fraudulent claim for purposes of
the federal False Claims Act or federal civil money penalties statute. Violations of the AKS carry potentially significant civil and criminal penalties, including imprisonment,
fines, administrative civil monetary penalties, and exclusion from participation in federal healthcare program;

The federal civil and criminal false claims and civil monetary penalties laws, including the federal False Claims Act ("FCA"), prohibit individuals or entities from, among
other things, knowingly presenting, or causing to be presented, to the federal government, claims for payment or approval that are false, fictitious or fraudulent; knowingly
making, using or causing to be made or used a false statement or record material to a false or fraudulent claim or obligation to pay or transmit money or property to the federal
government; or knowingly concealing or knowingly and improperly avoiding or decreasing an obligation to pay money to the federal government. Manufacturers can be held
liable  under  the  FCA  even  when  they  do  not  submit  claims  directly  to  government  payors  if  they  are  deemed  to  "cause"  the  submission  of  false  or  fraudulent  claims.
Companies that submit claims directly to payors also may be liable under the FCA for the direct submission of such claims. The FCA also permits a private individual acting
as a "whistleblower" to bring actions on behalf of the federal government alleging violations of the FCA and to share in any monetary recovery. When an entity is determined
to have violated the federal civil False Claims Act, the government may impose civil fines and penalties for each false claim, plus treble damages, and exclude the entity from
participation in Medicare, Medicaid and other federal healthcare programs;
the anti-inducement law prohibits, among other things, the offering or giving of remuneration, which includes, without limitation, any transfer of items or services for free or
for less than fair market value (with limited exceptions), to a Medicare or Medicaid beneficiary that the person knows or should know is likely to influence the beneficiary’s
selection of a particular supplier of items or services reimbursable by a federal or state governmental program;
the federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA"), as amended by the Health Information Technology for Economic and Clinical Health Act
of  2009  ("HITECH")  and  their  respective  implementing  regulations,  including  the  Final  Omnibus  Rule  published  in  January  2013,  which  impose  requirements  on  certain
covered healthcare providers, health plans, and healthcare clearinghouses as well as their respective business associates, independent contractors or agents of covered entities,
that perform services for them that involve the creation, maintenance, receipt, use, or disclosure of, individually identifiable health information relating to the privacy, security
and  transmission  of  individually  identifiable  health  information.  HITECH  also  created  new  tiers  of  civil  monetary  penalties,  amended  HIPAA  to  make  civil  and  criminal
penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce
the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, there may be additional federal, state and non-United
States laws which govern the privacy and security of health and other personal information in certain circumstances, many of which differ from each other in significant ways
and  may  not  have  the  same  effect,  thus  complicating  compliance  efforts.  In  addition,  HIPAA,  which  created  new  federal  criminal  statutes  that  prohibit  a  person  from
knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit  program  or  obtain,  by  means  of  false  or  fraudulent  pretenses,
representations or promises, any of the money or property owned by, or under the custody or control of, any healthcare benefit program, regardless of the payor (e.g., public or
private)  and  knowingly  and  willfully  falsifying,  concealing  or  covering  up  by  any  trick  or  device  a  material  fact  or  making  any  materially  false,  fictitious,  or  fraudulent
statements or representations in connection with the delivery of, or payment for, healthcare benefits, items or services relating to healthcare matters; similar to the federal Anti-
Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.
the federal false statements statute, which prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in
connection with the delivery of or payment for healthcare benefits, items or services;
the federal transparency requirements under the federal Physician Payments Sunshine Act requires certain manufacturers of drugs, devices, biologics, and medical supplies for
which  payment  is  available  under  Medicare,  Medicaid,  or  the  Children’s  Health  Insurance  Program,  with  specific  exceptions,  to  report  annually  to  the  HHS  information
regarding any payment or other "transfer of value" made or distributed to healthcare professionals (currently defined to include doctors, dentists, optometrists, podiatrists, and
chiropractors), certain other licensed healthcare practitioners and teaching hospitals, as well as ownership and investment interests held by the healthcare professionals and
their immediate family members. Failure to submit required information may result in civil monetary penalties for all payments, transfers of value or ownership or investment
interests that are not timely, accurately, and completely reported in an annual submission.
federal price reporting laws, which require manufacturers to calculate and report complex pricing metrics in an accurate and timely manner to government programs;
federal consumer protection and unfair competition laws, which broadly regulate marketplace activities and activities that potentially harm consumers; and
The Foreign Corrupt Practices Act ("FCPA"), which prohibits companies and their intermediaries from making, or offering or promising to make, improper payments to non-
United States officials for the purpose of obtaining or retaining business or otherwise seeking favorable treatment.

Additionally, we may be subject to state and non-United States equivalents of each of the healthcare laws described above, among others, some of which may be broader in scope and may apply
regardless of the payor. Many states have adopted laws similar to the federal Anti-Kickback Statute, some of which apply to the referral of patients for healthcare services reimbursed by any source,
not just governmental payors, including private insurers. In addition, some states have passed laws that require pharmaceutical companies to comply with the April 2003 Office of Inspector General
Compliance Program Guidance for Pharmaceutical Manufacturers and/or the Pharmaceutical Research and Manufacturers of America’s Code on Interactions with Healthcare Professionals. Several
states also impose other marketing restrictions or require pharmaceutical companies to make marketing or price disclosures to the state. There are

24

Table of Contents

ambiguities as to what is required to comply with these state requirements, and if we fail to comply with an applicable state law requirement, we could be subject to penalties. Finally, there are state
and  non-United  States  laws  governing  the  privacy  and  security  of  health  information,  many  of  which  differ  from  each  other  in  significant  ways  and  often  are  not  preempted  by  HIPAA,  thus
complicating compliance efforts.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge under
one or more of such laws.

Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including penalties, fines, disgorgement, imprisonment and/or exclusion or suspension from federal and state
healthcare programs such as Medicare and Medicaid and debarment from contracting with the United States government. In addition, private individuals have the ability to bring actions on behalf of
the United States government under the federal False Claims Act as well as under the false claims laws of several states.

Law enforcement authorities are increasingly focused on enforcing these laws, and it is possible that some of our practices may be challenged under these laws. Efforts to ensure that our current and
future business arrangements with third parties, and our business generally, will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental
authorities will conclude that our business practices, including our arrangements with physicians and other healthcare providers, may not comply with current or future statutes, regulations, agency
guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or
asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, disgorgement, monetary fines,
imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and
curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations. In addition, the approval and commercialization of any of our drug
candidates outside the United States also will likely subject us to non-United States equivalents of the healthcare laws mentioned above, among other non-United States laws.

If any of the physicians or other healthcare providers or entities with whom we expect to do business are found to be not in compliance with applicable laws, they may be subject to criminal, civil or
administrative sanctions, including exclusions from government funded healthcare programs, which also may adversely affect our business.

We may also be subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of
hazardous materials and wastes. From time to time and in the future, our operations may involve the use of hazardous and flammable materials, including chemicals and biological materials, and may
also produce hazardous waste products. Even if we contract with third parties for the disposal of these materials and waste products, we cannot completely eliminate the risk of contamination or
injury resulting from these materials. In the event of contamination or injury resulting from the use or disposal of our hazardous materials, we could be held liable for any resulting damages, and any
liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties for failure to comply with such laws and regulations.

We  maintain  workers’  compensation  insurance  to  cover  us  for  costs  and  expenses  we  may  incur  due  to  injuries  to  our  employees,  but  this  insurance  may  not  provide  adequate  coverage  against
potential liabilities. However, we do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. Current or future environmental laws and regulations may
impair our research, development or production efforts. In addition, failure to comply with these laws and regulations may result in substantial fines, penalties or other sanctions.

In the United States, to help patients afford our approved product, we may utilize programs to assist them, including patient assistance programs ("PAPs") and copay coupon programs for eligible
patients. PAPs are regulated by and subject to guidance from CMS Office of Inspector General's ("OIG"). In addition, at least one insurer has directed its network pharmacies to no longer accept
copay  coupons  for  certain  specialty  drugs  the  insurer  identified.  Our  copay  coupon  programs  could  become  the  target  of  similar  insurer  actions.  In  addition,  in  November  2013,  the  CMS  issued
guidance to the issuers of qualified health plans sold through the ACA’s marketplaces encouraging such plans to reject patient cost-sharing support from third parties and indicating that the CMS
intends to monitor the provision of such support and may take regulatory action to limit it in the future. The CMS subsequently issued a rule requiring individual market qualified health plans to
accept third-party premium and cost-sharing payments from certain government-related entities. In September 2014, the OIG of the HHS issued a Special Advisory Bulletin warning manufacturers
that they may be subject to sanctions under the federal anti-kickback statute and/or civil monetary penalty laws if they do not take appropriate steps to exclude Part D beneficiaries from using copay
coupons. Accordingly, companies exclude these Part D beneficiaries from using copay coupons.

Healthcare Reform

A primary trend in the United States healthcare industry and elsewhere is cost containment. Government authorities and other third-party payors have attempted to control costs by limiting coverage
and  the  amount  of  reimbursement  for  particular  medical  products.  For  example,  in  March  2010,  the  Patient  Protection  and  Affordable  Care  Act,  as  amended  by  the  Health  Care  and  Education
Reconciliation Act of 2010 ("ACA") was enacted in the United States. The ACA includes measures that have significantly changed,

25

Table of Contents

and  are  expected  to  continue  to  significantly  change,  the  way  healthcare  is  financed  by  both  governmental  and  private  insurers.  Among  the  provisions  of  the  ACA  of  greatest  importance  to  the
pharmaceutical industry are that the ACA:

Made  several  changes  to  the  Medicaid  Drug  Rebate  Program,  including  increasing  pharmaceutical  manufacturers’  rebate  liability  by  raising  the  minimum  basic  Medicaid
rebate on most branded prescription drugs.
Imposed a requirement on manufacturers of branded drugs to provide a 70% point-of-sale discount off the negotiated price of branded drugs dispensed to Medicare Part D
beneficiaries in the coverage gap (i.e., "donut hole") as a condition for a manufacturer’s outpatient drugs being covered under Medicare Part D.
Extended a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations.
Expanded the entities eligible for discounts under the 340B Drug Discount Program.
Imposed  an  annual,  nondeductible  fee  on  any  entity  that  manufactures  or  imports  certain  branded  prescription  drugs,  apportioned  among  these  entities  according  to  their
market share in certain government healthcare programs.
Established a Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness research, along with funding for
such research. The research conducted by the Patient-Centered Outcomes Research Institute may affect the market for certain pharmaceutical products. The ACA established
the Center for Medicare and Medicaid Innovation within CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending, potentially
including prescription drug spending.

In addition, other legislative and regulatory changes have been proposed and adopted in the United States since the ACA was enacted:













The United States Budget Control Act of 2011, among other things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year through 2031.
On January 2, 2013, the United States American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several
types of providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.
On April 13, 2017, CMS published a final rule that gives states greater flexibility in setting benchmarks for insurers in the individual and small group marketplaces, which
may have the effect of relaxing the essential health benefits required under the ACA for plans sold through such marketplaces.
On May 23, 2019, CMS published a final rule to allow Medicare Advantage Plans the option of using step therapy for Part B drugs beginning January 1, 2020.
Due  to  the  Statutory  Pay-As-You-Go  Act  of  2010,  estimated  budget  deficit  increases  resulting  from  the  American  Rescue  Plan  Act  of  2021,  and  subsequent  legislation,
Medicare payments to providers will be further reduced starting in 2025 absent further legislation.
In  August  2022,  the  Inflation  Reduction  Act  of  2022,  or  IRA  was  signed  into  law.  The  IRA  includes  several  provisions  that  will  impact  our  business  to  varying  degrees,
including provisions that reduce the out-of-pocket cap for Medicare Part D beneficiaries to $2,000 starting in 2025; impose new manufacturer financial liability on certain
drugs in Medicare Part D, allow the United States government to negotiate Medicare Part B and Part D price caps for certain high-cost drugs and biologics without generic or
biosimilar competition, require companies to pay rebates to Medicare for certain drug prices that increase faster than inflation, and delay the rebate rule that would limit the
fees that pharmacy benefit managers can charge. Further, under the IRA, orphan drugs are exempted from the Medicare drug price negotiation program, but only if they have
one orphan designation and for which the only approved indication is for that disease or condition. If a product receives multiple orphan designations or has multiple approved
indications, it will not qualify for the orphan drug exemption. The implementation of the IRA is currently subject to ongoing litigation challenging the constitutionality of the
IRA’s Medicare drug price negotiation program The effects of the IRA on our business and the healthcare industry in general is not yet known.

There  has  been  increasing  legislative  and  enforcement  interest  in  the  United  States  with  respect  to  specialty  drug  pricing  practices.  Specifically,  there  have  been  several  recent  United  States
Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare,
review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. At a federal level, President Biden has issued
multiple executive orders that have sought to reduce prescription drug costs. In February 2023, HHS also issued a proposal in response to an October 2022 executive order from President Biden that
includes a proposed prescription drug pricing model that will test whether targeted Medicare payment adjustments will sufficiently incentivize manufacturers to complete confirmatory trials for drugs
approved through FDA’s accelerated approval pathway. Although a number of these and other proposed measures may require authorization through additional legislation to become effective, and the
Biden administration may reverse or otherwise change these measures, both the Biden administration and Congress have indicated that they will continue to seek new legislative measures to control
drug costs.

At  the  state  level,  legislatures  have  increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  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.

26

 
 
Table of Contents

We expect that additional foreign, federal and state healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for
healthcare  products  and  services,  which  could  result  in  limited  coverage  and  reimbursement  and  reduced  demand  for  our  products  or  product  candidates,  once  approved,  or  additional  pricing
pressures.

Coverage and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any product candidate for which we obtain regulatory approval. In the United States and markets in other countries, sales
of any product candidates for which we receive regulatory approval for commercial sale will depend, in part, on the availability of coverage and reimbursement from third-party payors. Third-party
payors include government authorities, managed care providers, private health insurers and other organizations. The process for determining whether a payor will provide coverage for a product may
be separate from the process for setting the reimbursement rate that the payor will pay for the product. Third-party payors may limit coverage to specific products on an approved list, or formulary,
which  might  not  include  all  of  the  FDA-approved  products  for  a  particular  indication.  A  decision  by  a  third-party  payor  not  to  cover  our  products  or  product  candidates  could  reduce  physician
utilization of our products once approved and have a material adverse effect on our sales, results of operations and financial condition. Moreover, a payor’s decision to provide coverage for a product
does  not  imply  that  an  adequate  reimbursement  rate  will  be  approved.  Adequate  third-party  reimbursement  may  not  be  available  to  enable  us  to  maintain  price  levels  sufficient  to  realize  an
appropriate return on our investment in product development.

In addition, coverage and reimbursement for products can differ significantly from payor to payor. One third-party payor’s decision to cover a particular pharmaceutical drug product or service does
not  ensure  that  other  payors  will  also  provide  coverage  for  the  pharmaceutical  drug  product  or  service  or  will  provide  coverage  at  an  adequate  reimbursement  rate.  As  a  result,  the  coverage
determination process will require us to provide scientific and clinical support for the use of our products to each payor separately and will be a time-consuming process. Factors payors consider in
determining reimbursement are based on whether the 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.

Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of pharmaceutical drug products and services, in addition to their safety and
efficacy.  In  order  to  obtain  and  maintain  coverage  and  reimbursement  for  any  product,  we  may  need  to  conduct  expensive  clinical  trials  in  order  to  demonstrate  the  medical  necessity  and  cost-
effectiveness of such product, in addition to the costs required to obtain regulatory approvals. Our products may not be considered medically necessary or cost-effective. If third-party payors do not
consider a product to be cost-effective compared to other available therapies, they may not cover the product as a benefit under their plans or, if they do, the level of payment may not be sufficient to
allow a company to sell its products at a profit.

The  United  States  government,  state  legislatures  and  foreign  governments  have  shown  significant  interest  in  implementing  cost  containment  programs  to  limit  the  growth  of  government-paid
healthcare  costs,  including  price  controls,  restrictions  on  reimbursement  and  requirements  for  substitution  of  generic  products  for  branded  prescription  drugs.  For  example,  the  ACA  contains
provisions that may reduce the profitability of drug products through increased rebates for drugs reimbursed by Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans,
mandatory discounts for certain Medicare Part D beneficiaries and annual fees based on pharmaceutical companies’ share of sales to federal healthcare programs. Adoption of general controls and
measures, coupled with the tightening of restrictive policies in jurisdictions with existing controls and measures, could limit payments for pharmaceutical drugs.

The  Medicare  Prescription  Drug,  Improvement,  and  Modernization  Act  of  2003  ("MMA")  established  the  Medicare  Part  D  program  to  provide  a  voluntary  prescription  drug  benefit  to  Medicare
beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private entities that provide coverage of outpatient prescription drugs. While all Medicare drug
plans must give at least a standard level of coverage set by Medicare, Part D prescription drug plan sponsors are not required to pay for all covered Part D drugs, and each drug plan can develop its
own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D prescription drug formularies must include drugs within each therapeutic category and class of
covered Part D drugs, though not necessarily all the drugs in each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and
therapeutic committee. Any negotiated prices for any of our products covered by a Part D prescription drug plan will likely be lower than the prices we might otherwise obtain. Moreover, while the
MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in setting their own payment rates. Any reduction in
payment that results from the MMA may result in a similar reduction in payments from non-governmental payors.

In  addition,  there  have  been  several  changes  to  the  340B  drug  pricing  program,  which  imposes  ceilings  on  prices  that  drug  manufacturers  can  charge  for  medications  sold  to  certain  health  care
facilities. On November 3, 2023, the U.S. District Court of South

27

 
Table of Contents

Carolina issued an opinion in Genesis Healthcare Inc. v. Becerra et al. that may lead to an expansion of the scope of patients eligible to access prescriptions at 340B pricing. The outcome of this
judicial proceeding is uncertain. It is unclear how these developments could affect covered hospitals who might purchase our future products and affect the rates we may charge such facilities for our
approved products in the future, if any. We continue to review developments impacting the 340B program.

The American Recovery and Reinvestment Act of 2009 provides funding for the federal government to compare the effectiveness of different treatments for the same illness. The plan for the research
was published in 2012 by HHS, the Agency for Healthcare Research and Quality and the National Institutes for Health, and periodic reports on the status of the research and related expenditures are
made to Congress. Although the results of the comparative effectiveness studies are not intended to mandate coverage policies for public or private payors, it is not clear what effect, if any, the
research  will  have  on  the  sales  of  our  drugs,  if  any  such  drug  or  the  condition  that  they  are  intended  to  treat  are  the  subject  of  a  trial.  It  also  is  possible  that  comparative  effectiveness  research
demonstrating  benefits  in  a  competitor’s  drug  could  adversely  affect  the  sales  of  our  drugs  after  approval.  If  third-party  payors  do  not  consider  our  drugs  to  be  cost-effective  compared  to  other
available therapies, they may not cover our drugs after approval as a benefit under their plans or, if they do, the level of payment may not be sufficient to allow us to sell our drugs on a profitable
basis.

These laws and future state and federal healthcare reform measures may be adopted in the future, any of which may result in additional reductions in Medicare and other healthcare funding and
otherwise affect the prices we may obtain for any of our products or product candidates for which we may obtain regulatory approval or the frequency with which any such product is prescribed or
used.

As noted above, the marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide adequate coverage
and reimbursement. We expect that an increasing emphasis on cost containment measures in the United States will continue to increase the pressure on pharmaceutical pricing. 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 of our products or product candidates for which we receive
regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Human Capital Resources

As  of  December  31,  2023,  we  had  377  full-time  employees  in  the  United  States,  216  of  whom  were  primarily  engaged  in  sales  and  marketing,  121  of  whom  were  primarily  engaged  in  general
administration, and 40 of whom were primarily engaged in product development and research.

We believe our success will depend on, among other things, our ability to continue to hire and retain the necessary qualified personnel across all departments in our organization, as we expand the
commercialization of our products. Our President and Chief Operating Officer and Vice President, Human Resources are responsible for developing and executing our human capital strategy. This
includes the attraction, acquisition, development and engagement of talent to deliver on the Company’s strategy. The executive management team regularly updates our board of directors and its
committees on the operation and status of our human capital trends and activities.

Diversity, Equity and Inclusion

We are committed to building a company that provides an inclusive environment where we invite and encourage diverse perspectives, ideas, and people. With that goal in mind, we have established a
committee comprised of employees and sponsored by key executive team members to continue building a strategic plan designed to promote a diverse and inclusive work environment. We believe
these initiatives and a workforce with diverse backgrounds, experiences and viewpoints will continue to help the Company achieve innovative solutions to the business challenges. In addition, we
have sought to implement recruiting practices and to work with recruiting partners who can help us best identify and attract diverse candidates. We continue to expand our systems to track key human
capital metrics such as demographics, diversity, compensation and benefits, and engagement and to think of new ways to best support our female and underrepresented employees to help advance
their careers.

Training and Talent Development

We believe that our employees are the key to our success, and we believe their development is what drives our growth and prosperity as a company. To support employee development, as well as plan
for  short-  and  long-term  business  success,  we  review  and  update  a  company  succession  plan  regularly  and  we  offer  a  number  of  development  opportunities  for  our  employees  through  various
methods. Our succession plan is reviewed with the board annually. In addition, upon joining the company, all new employees are required to become familiar with our policies, including our Code of
Business Conduct and Ethics and Employee Handbook, and complete compliance training, and existing employees are required to acknowledge current policies annually.

Compensation and Benefits

An important part of attracting and retaining key talent is competitive pay and benefits. To ensure our compensation and benefits programs are competitive, we engage nationally recognized outside
compensation and benefits consulting firms to independently evaluate the effectiveness of our programs and to provide benchmarking against our peers within the industry. Our pay for performance
philosophy seeks to motivate and reward employees while accomplishing the Company’s short and long-term strategic goals. As part of a robust performance management process, employees are
evaluated both on what they accomplished and how they

28

Table of Contents

demonstrated our values. Annual salary increases and incentive bonuses are based on both individual and corporate performance factors.

As a long-term incentive, to encourage our employees to think like owners and share in the Company’s long-term success, employees are granted equity in the form of stock options or restricted stock
units and can elect to participate in our employee stock purchase plan. Employees are generally eligible for health insurance, paid and unpaid leaves including paid parental leave, paid caregiver
leave, retirement plans with an employer contribution match, life and disability/accident coverage, parking or commuter assistance, an employee assistance program providing mental health, legal and
financial health resources, and a wellness reimbursement benefit.

Health and Safety

We  are  committed  to  the  safety  of  our  employees  and  the  communities  we  serve.  We  provide  regular  health  and  safety  training  programs  for  employees,  which  includes,  upon  on-boarding,  an
overview  during  new  hire  orientation,  as  well  as  ongoing  training  throughout  the  year.  Employees  are  trained  on  workplace  safety,  including  security  and  inspection,  work  related  injuries  and
emergency protocols as applicable for their role and work location. In addition, special health and safety training is conducted for laboratory staff.

ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. Careful consideration should be given to the following risk factors, in evaluating us and our business. If any of the following risks and
uncertainties actually occurs, our business, prospects, financial condition and results of operations could be materially and adversely affected. The risks summarized and described below are not
intended to be exhaustive and are not the only risks facing us. New risk factors can emerge from time to time, and it is not possible to predict the impact that any factor or combination of factors may
have on our business, prospects, financial condition and results of operations.

Risks Related to our Financial Position and Need for Financing

Risks Related to Our Operating History

As a company, we have a limited operating history and limited experience commercializing pharmaceutical products and have incurred significant losses since inception.

Historically, we have funded our operations primarily through private placements of convertible preferred stock, public offerings of common stock and convertible notes, and debt issuances. We have
five pharmaceutical products that were commercially launched in the past six years, i.e., Keveyis (2017), Gvoke PFS (2019), Gvoke HypoPen (2020), Recorlev (2022) and Gvoke Kit (2022). We are
in the early stages of commercializing our biopharmaceutical products and have a limited operating history.

We have incurred significant losses in every fiscal year since inception. For the years ended December 31, 2023, 2022 and 2021, we reported a net loss of $62.3 million, $94.7 million and $122.7
million, respectively. In addition, our accumulated deficit as of December 31, 2023 was $617.0 million.

We expect to continue to incur significant operating expenses as we continue the commercialization of Gvoke, Recorlev and Keveyis, develop, enhance and commercialize new products, and incur
additional operational and reporting costs associated with being a public company. In particular, we anticipate that we will continue to incur significant expenses as we:






execute our Gvoke, Recorlev and Keveyis commercial strategies in the United States;
continue our research and development efforts;
seek regulatory approval for new product candidates and product enhancements; and
continue to operate as a public company.

Biopharmaceutical  product  development  is  a  highly  speculative  undertaking  and  involves  a  substantial  degree  of  risk.  Accordingly,  you  should  consider  our  prospects  in  light  of  the  costs,
uncertainties, delays and difficulties frequently encountered by companies prior to and at the early stages of commercialization of any product candidates, especially biopharmaceutical companies
such as ours. Any predictions you make about our future success or viability may not be as accurate as they could be if we had a longer operating history or a history of successfully commercializing
biopharmaceutical products. We may encounter unforeseen expenses, difficulties, complications, delays and other known or unknown factors in achieving our business objectives. We will need to
successfully execute our commercialization strategy and may not be successful in doing so. We expect our financial condition and operating results to continue to fluctuate significantly from quarter
to quarter and year to year due to a variety of factors, many of which are beyond our control. Accordingly, you should not rely upon the results of any quarterly or annual periods as indications of
future operating performance.

We may never be profitable or be able to sustain revenues or, if achieved, sustain profitability in the future and we may not be able to continue operations without additional fundings.

Our ability to generate revenue from Gvoke, Recorlev and Keveyis, and our product candidates, if successfully developed and approved, depends on a number of factors, including, but not limited to,
our ability to:















obtain commercial quantities of our products at acceptable cost levels;
successfully manage inventory;
sell and distribute our products on terms acceptable to us;
achieve  an  adequate  level  of  market  acceptance  of  our  products  in  the  medical  community  and  with  third-party  payors,  including  placement  in  accepted  clinical  guidelines  for  the
conditions for which our product candidates are intended to target;
obtain and maintain third-party coverage and adequate reimbursement for our products;
compete effectively against our competitors; and
launch and commercialize our products utilizing our own sales force or by entering into partnership or co-promotion arrangements with third parties.

30

Table of Contents

We have incurred and expect to continue to incur significant sales and marketing costs as we commercialize Gvoke, Recorlev and Keveyis. Regardless of these expenditures, our products and our
product  candidates,  if  developed  and  approved,  may  not  be  commercially  successful.  Although  we  generate  revenue  from  Gvoke,  Recorlev  and  Keveyis,  if  we  are  unable  to  generate  sufficient
product revenue, we will not become profitable. Our failure to become and remain profitable would depress the market price of our common stock and could impair our ability to raise capital, expand
our business, diversify our product offerings or continue our operations. If we continue to suffer losses as we have in the past, investors may not receive any return on their investment and may lose
their entire investment.

Risks Related to Future Financial Condition

We may require additional capital to sustain our business, and this capital may cause dilution to our stockholders and might not be available on terms favorable to us, or at all, which could force
us to delay, reduce or eliminate our product development programs or commercialization efforts.

Biopharmaceutical development is a time consuming, expensive and uncertain process that takes years to complete. We are incurring significant commercialization expenses related to product sales,
marketing, manufacturing, packaging and distribution of Gvoke, Recorlev and Keveyis and expect to continue to incur such expenses for our products, as well as for any of our product candidates, if
approved. We expect to require additional capital to complete the clinical trials associated with our product candidates and begin commercialization efforts, if approved. Accordingly, we may need
additional funding in connection with our continuing operations. In the future, if we are unable to raise capital when needed or on attractive terms, we may be forced to delay, reduce or eliminate our
research and development programs and/or sales and marketing activities. Market volatility, including due to geopolitical instability, rising interest rates, fluctuations in inflation rates, the tightening
of lending standards, any further deterioration in the macroeconomic economy or financial services industry resulting from actual or potential bank failures, or other factors could also materially and
adversely impact our ability to access capital as and when needed and increase our cost of capital even if available.

We may be required to or choose to obtain further funding through public equity offerings, debt financings, royalty-based financing arrangements, collaborations and licensing arrangements or other
sources. If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we
issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing obtained by us would be senior to our common stock, would likely cause us
to incur significant interest expense or other costs, and could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may increase our
expenses and make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions and in-licensing opportunities. Under our existing credit
facility dated March 8, 2022, as amended (the "Hayfin Loan Agreement"), with the lenders from time to time parties thereto (the "Lenders"), Hayfin Services LLP, as administrative agent for the
Lenders, Xeris Pharmaceuticals, Inc., Xeris Biopharma Holdings, Inc. and our subsidiaries party thereto, we are restricted in our ability to incur additional indebtedness and to pay dividends. Any
additional debt financing that we may secure in the future could include similar or more restrictive covenants relating to our capital raising activities, buying or selling assets and other financial and
operational matters, which may make it more difficult for us to obtain additional capital, manage our business and pursue business opportunities. We may also be required to secure any such debt
obligations with some or all of our assets. For example, our Hayfin Loan Agreement is secured by substantially all of our property and assets, including our intellectual property assets, subject to
certain exceptions.

If we raise additional funds through collaborations or marketing, distribution or licensing, or royalty-based financing arrangements with third parties, we may have to relinquish valuable rights to our
technologies, future revenue streams or product candidates or grant licenses on terms that may not be favorable to us. Securing financing could require a substantial amount of time and attention from
our management and may divert a disproportionate amount of their attention away from day-to-day activities, which may adversely affect our management’s ability to oversee the commercialization
of our products and development and commercialization, if approved, of our product candidates. It is also possible that we may allocate significant amounts of capital toward solutions or technologies
for which market demand is lower than anticipated and, as a result, abandon such efforts. Any of these negative developments could have a material adverse effect on our business, operating results,
financial condition and common stock price.

We may not have cash available to us in an amount sufficient to enable us to make interest or principal payments on our indebtedness when due, or to repurchase our Convertible Notes for cash
following a fundamental change, if required, and our existing and future indebtedness may limit our ability to repurchase the Convertible Notes.

On June 30, 2020, we completed a public offering of $86.3 million aggregate principal amount of our 5.00% Convertible Senior Notes due 2025 (the "2025 Convertible Notes"), including $11.3
million pursuant to the underwriters' option to purchase additional notes which was exercised in July 2020. A total principal amount of $39.1 million of Convertible Notes converted into equity in the
second half of 2020. On September 29, 2023, we completed the exchange of $31,975,000 in aggregate principal amount of the 2025 Convertible Notes for $33,574,000 in aggregate principal amount
of new 8.00% Convertible Senior Notes due 2028 (the "2028 Convertible Notes" and together with the 2025 Convertible Notes, the "Convertible Notes"). As of December 31, 2023, the outstanding
balance of the 2025 Convertible Notes was $15.2 million and the outstanding balance of the 2028 Convertible Notes was $33.6 million. The 2025 Convertible Notes are governed by the terms of a
base  indenture  for  senior  debt  securities  dated  June  30,  2020  (the  "2025  Base  Indenture"),  as  supplemented  by  the  first  supplemental  indenture  thereto  dated  June  30,  2020  and  the  second
supplemental indenture thereto dated October 5, 2021 (collectively, the "2025 Supplemental Indentures" and together with the 2025 Base Indenture, the "2025 Indenture"), each between us and U.S.
Bank Trust Company, National Association (f/k/a U.S. Bank National Association) ("U.S. Bank"), as trustee. The 2028 Convertible Notes are governed by the terms of an indenture for senior debt

31

Table of Contents

securities dated September 29, 2023 (the "2028 Indenture" and together with the 2025 Indenture, the "Indentures") between us and U.S. Bank, as trustee. Failure to satisfy our current and future debt
obligations under the Indentures could result in an event of default and, as a result, all of the amounts outstanding could immediately become due and payable. In the event of an acceleration of
amounts due under the Indentures as a result of an event of default, we may not have sufficient funds or may be unable to arrange for additional financing to repay our indebtedness.

Noteholders may require us to repurchase their Convertible Notes following a fundamental change at a cash repurchase price generally equal to the principal amount of the Convertible Notes to be
repurchased, plus accrued and unpaid interest, if any. A fundamental change includes certain acquisition transactions and the failure of our common stock to be listed on the Nasdaq Global Select
Market or certain similar national securities exchanges. We may not have enough available cash or be able to obtain financing at the time we are required to repurchase the Convertible Notes. In
addition,  applicable  law,  regulatory  authorities  and  the  agreements  governing  our  existing  and  future  indebtedness  may  restrict  our  ability  to  repurchase  the  Convertible  Notes.  Our  failure  to
repurchase the Convertible Notes when required will constitute a default under the Indentures that govern the Convertible Notes. A default under the Indentures or the fundamental change itself could
also  lead  to  a  default  under  agreements  governing  our  other  existing  or  future  indebtedness,  which  may  result  in  that  other  indebtedness  becoming  immediately  payable  in  full.  For  instance,  a
fundamental change without lender consent would constitute an event of default under our Hayfin Loan Agreement. We may not have sufficient funds to satisfy all amounts due under the other
indebtedness and the Convertible Notes.

In  addition,  we  have  $150.0  million  of  term  loans  outstanding  under  our  Hayfin  Loan  Agreement  as  of  December  31,  2023.  All  obligations  under  our  Hayfin  Loan  Agreement  are  secured  by
substantially all of our property and assets, including our intellectual property assets, subject to certain limited exceptions. The term loans and the Convertible Notes may create additional financial
risk for us, particularly if our business or prevailing financial market conditions are not conducive to paying off or refinancing our outstanding debt obligations at maturity. Failure to satisfy our
current and future debt obligations under our Hayfin Loan Agreement could result in an event of default thereunder and, as a result, our lenders could accelerate all amounts due. Events of default
also include our failure to comply with customary affirmative and negative covenants as well as a default under any indenture or other agreement governing convertible indebtedness permitted by the
Hayfin  Loan  Agreement,  including  the  Indentures.  The  Hayfin  Loan  Agreement  contains  customary  representations  and  warranties,  events  of  default  and  affirmative  and  negative  covenants,
including,  among  others,  covenants  that  limit  or  restrict  our  ability  to  incur  additional  indebtedness,  grant  liens,  merge  or  consolidate,  make  acquisitions,  pay  dividends  or  other  distributions  or
repurchase equity, make investments, dispose of assets and enter into certain transactions with affiliates, in each case subject to certain exceptions. In the event of an acceleration of amounts due
under our Hayfin Loan Agreement as a result of an event of default, we may not have sufficient funds or may be unable to arrange for additional financing to repay our indebtedness. In addition, our
lenders could seek to enforce their security interests in any collateral securing such indebtedness.

Our PPP Loan, which we repaid in full in June 2020, was subject to the terms and conditions applicable to loans administered by the SBA under the CARES Act, and we may be subject to an
audit or enforcement action related to the PPP Loan.

On April 21, 2020, we entered into the United States Small Business Administration (the "SBA") PPP Note (the "Note") with Silicon Valley Bank (the "PPP Lender") for a loan in the amount of $5.1
million (the "PPP Loan") enabled by the Coronavirus Aid, Relief and Economic Security Act of 2020 (the "CARES Act"). We received the full amount of the PPP Loan on April 22, 2020. On May 4,
2020, we repaid $0.9 million of the PPP Loan. In June 2020, we repaid the remaining amount outstanding under the PPP Loan in connection with the concurrent 2025 Convertible Notes and equity
offerings.

We may be subject to CARES Act-specific lookbacks and audits until May of 2026 that may be conducted by other federal agencies, including several oversight bodies created under the CARES Act.
These bodies have the ability to coordinate investigations and audits and refer matters to the Department of Justice for civil or criminal enforcement and other actions. Complying with such SBA
audit could divert management resources and attention and require us to expend significant time and resources, which could have an adverse effect on our business, financial condition and results of
operations.

Greater than expected product returns may exceed our reserve for returns.

We use various factors to estimate the provision for returns, including the launch date of products, historical customer return rates, third-party industry data for comparable products in the market and
estimated  channel  inventory  data.  In  a  reporting  period,  we  may  decide  to  constrain  revenue  for  product  returns  based  on  information  from  various  sources,  including  channel  inventory  levels,
inventory dating, prescription data, the expiration dates of product, price changes of competitive products and introductions of generic products. Any significant increase in returns that exceeds our
reserves could adversely affect our revenue and operating results.

We use data from third parties as part of our return reserves calculation. We are reliant on these third parties to ensure that the data they provide is accurate. Inaccurate data could cause us to estimate
our return reserves incorrectly and could have an adverse impact on our results of operations and financial condition.

Risks Related to the Commercialization and Marketing of our Products and Product Candidates

Risks Related to Commercialization and Marketing

Our business depends entirely on the commercial success of our products and product candidates. Even if approved, our product candidates may not be accepted in the marketplace and our
business may be materially harmed.

32

Table of Contents

To date, we have expended significant time, resources, and effort on the development of our product candidates, and a substantial portion of our resources recently has been and will continue to be
focused on marketing and commercializing our approved products, Gvoke, Recorlev and Keveyis, in the United States. Our business and future success are substantially dependent on our ability to
generate and increase product revenue in the near term. Our estimates of the potential market opportunity for Gvoke, Recorlev, Keveyis, and our product candidates include several key assumptions
of  the  current  market  size  and  current  pricing  for  commercially  available  products  and  are  based  on  industry  and  market  data  obtained  from  industry  publications,  studies  conducted  by  us,  our
industry knowledge, third-party research reports and other surveys. While we believe that our internal assumptions are reasonable, if any of these assumptions proves to be inaccurate, the actual
market for our product and product candidates could be smaller than our estimates of our potential market opportunity. Our product candidates are in various stages of development and subject to the
risks  of  failure  inherent  in  developing  drug  products.  Any  delay  or  setback  in  the  regulatory  approval,  product  launch,  commercialization  or  distribution  of  any  of  our  product  candidates  will
adversely  affect  our  business.  The  infrastructure,  systems,  processes,  policies,  relationships  and  materials  we  have  built  for  the  commercialization  of  Gvoke,  Recorlev  and  Keveyis  may  not  be
sufficient for us to achieve success at the levels we expect. Further, our products may contain undetected manufacturing defects, including mislabeling, which might require product replacement, re-
labeling or product recalls, which could further harm our business. For more information, see the section entitled, "Business — Coverage and Reimbursement".

Even if all regulatory approvals are obtained, the commercial success of our products and product candidates will depend on gaining and maintaining market acceptance among physicians, patients,
patient advocacy groups, healthcare payors and the medical community. The degree of market acceptance of our products and product candidates will depend on many factors, including whether our
products and product candidates are:











a covered benefit under health plans;
safe, effective and medically necessary;
appropriate for the specific patient;
cost-effective; and
neither experimental nor investigational.

Additionally, if, after obtaining marketing approval of any of our products or product candidates, we or others later identify undesirable or unacceptable side effects caused by such products, a number
of potentially significant negative consequences could result, including:

















regulatory authorities may withdraw approvals of such product, require us to take our approved product off the market or ask us to voluntarily remove the product from the market;
regulatory authorities may require the addition of labeling statements, specific warnings, contraindications or the issuance of field alerts to physicians and pharmacies;
regulatory authorities may impose conditions under a risk evaluation and mitigation strategy ("REMS") including distribution of a medication guide to patients outlining the risks of
such side effects or imposing distribution or use restrictions;
we may be required to change the way a product is administered, conduct additional clinical trials or change the labeling of the product;
we may be subject to limitations on how we may promote the product;
sales of the product may decrease significantly;
we may be subject to litigation or products liability claims; and
our reputation may suffer.

If  our  product  candidates  are  approved  but  do  not  achieve  an  adequate  level  of  acceptance  by  physicians,  patients  and  third-party  payors,  we  may  never  generate  significant  revenue  from  these
product candidates, and our business, financial condition and results of operations may be materially harmed. Even if our products achieve market acceptance, we may not be able to maintain that
market acceptance over time if new therapeutics are introduced that are more favorably received than our products or that render our products obsolete, or if significant adverse events occur. If our
products do not achieve and maintain market acceptance, we will not be able to generate sufficient revenue from product sales to attain profitability.

We operate in a competitive business environment, which may have an adverse impact on our revenue. If we are unable to compete successfully against our existing or future competitors, our
sales and operating results may be negatively affected and we may not successfully commercialize our products or product candidates, even if approved.

The pharmaceutical and biotechnology industries are characterized by intense competition and significant and rapid technological change as researchers learn more about diseases and develop new
technologies and treatments. Any product candidates that we successfully develop and commercialize will compete with existing drugs and new drugs that may become available in the future. While
we  believe  that  our  product  and  product  candidate  platform,  development  expertise  and  scientific  knowledge  provide  us  with  competitive  advantages,  we  face  potential  competition  from  many
different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions, governmental agencies and public and private research

33

Table of Contents

institutions. Many of our current and potential competitors are major pharmaceutical companies that have substantially greater financial, technical and marketing resources than we do, and they may
succeed in developing products that would render our products obsolete or noncompetitive. Our ability to compete successfully will depend on our ability to develop future products that reach the
market in a timely manner, are well adopted by patients and healthcare providers and receive adequate coverage and reimbursement from third-party payors. Competitors may also develop and patent
processes or products earlier than we can or obtain regulatory clearance or approvals for competing products more rapidly than we can, which could impair our ability to develop and commercialize
similar processes, or products. If alternative treatments are, or are perceived to be, superior to our products, sales of our products or product candidates, if approved, could be negatively affected and
our results of operations could suffer. Because of the size of the potential market for certain of our products and product candidates, we anticipate that companies will dedicate significant resources to
developing products competitive to such products and product candidates.

For example, Gvoke has numerous competitors in the severe hypoglycemia market, which currently include Amphastar’s Baqsimi, an intranasal glucagon dry powder, Zealand Pharma’s Zegalogue, a
dasiglucagon  outlicensed  to  Novo  Nordisk,  Novo  Nordisk’s  GlucaGen  HypoKit,  Fresenius  Kabi's  glucagon  emergency  kit  for  low  blood  sugar,  and  Amphastar’s  generic  Glucagon  for  Injection
Emergency  Kit.  At  any  time,  these  or  other  industry  participants  may  develop  alternative  treatments,  products,  or  procedures  for  the  treatment  of  severe  hypoglycemia  that  compete  directly  or
indirectly with Gvoke.

Keveyis (dichlorphenamide) is an oral carbonic anhydrase inhibitor that was approved in the United States to treat hyperkalemic, hypokalemic, and related variants of PPP for which orphan drug
exclusivity ended on August 7, 2022. Torrent Pharmaceuticals Limited’s ANDA for generic dichlorphenamide was approved on December 29, 2022 and now competes with Keveyis, which may
adversely impact our revenue. In addition, due to the end of orphan drug exclusivity, we expect that additional generic competitors could emerge which may also contribute to the erosion of Keveyis
sales. Acetazolamide, another oral carbonic anhydrase inhibitor, is used frequently off-label for the prophylactic and sometimes acute treatment of PPP. Potassium supplements are indicated for use in
hypokalemic periodic paralysis in the United States and are frequently used either chronically or for emergency treatment of episodes in that form of PPP. Several other types of drugs have been
reported to have benefits for chronic or acute use in one or more than one PPP variant, including potassium-sparing diuretics, beta receptor agonists, mexelitine and other sodium channel blockers,
and others. We are not aware of drugs currently in development for prophylactic chronic treatment of PPP.

We  are  also  currently  aware  of  various  companies  that  are  marketing  existing  drugs  that  may  compete  with  Recorlev,  such  as  Corcept  Therapeutics  and  Recordati.  The  treatment  of  endogenous
Cushing's syndrome patients who fail or are ineligible for surgery in the United States and Europe are: Korlym (mifepristone) marketed by Corcept Therapeutics in the United States; Signifor LAR
(pasireotide) and Isturisa (osilodrostat), both marketed by Recordati in the United States and EU; and ketoconazole, metyrapone and mitotane marketed by HRA in the EU. Corcept is developing
relacorilant,  a  second-generation  glucocorticoid  receptor  modulator;  currently  in  Phase  3.  Ketoconazole  is  used  off-label  for  treatment  of  Cushing's  syndrome  in  the  United  States.  Regulatory
approval of ketoconazole for the treatment of endogenous Cushing's syndrome in the United States, which is not currently being sought by any sponsor to our knowledge, could significantly increase
competition for Recorlev due to the similar mechanisms of action between the drug products.

If we are unable to establish or do not maintain sufficient marketing, sales and distribution capabilities or enter into agreements with third parties to market, sell and distribute our products on
terms acceptable to us, we may not be able to generate product revenue and our business, results of operations, and financial condition will be materially adversely affected.

We have developed our commercial infrastructure for the sales, marketing and distribution of Gvoke, Recorlev and Keveyis. In order to successfully commercialize our product candidates, we will
need to maintain and may need to expand our marketing, sales, distribution, managerial and other non-technical capabilities and/or make arrangements with third parties to perform some or all of
these services. We have established our sales force to market our products in the United States. In order to maintain and, if needed, expand our sales force, we will compete with other companies to
recruit, hire, train and retain sales and marketing personnel. There are significant expenses and risks involved with maintaining and, if needed, expanding, our own sales and marketing capabilities,
including  our  ability  to  hire,  retain  and  appropriately  incentivize  qualified  individuals,  generate  sufficient  sales  leads,  obtain  access  to  an  adequate  number  of  physicians  and  persuade  them  to
prescribe our products and any product candidates that receive regulatory approval, provide adequate training to sales and marketing personnel, and effectively manage a geographically dispersed
sales and marketing team. Any failure or delay in our ability to maintain or expand, if needed, our internal sales, marketing and distribution capabilities would adversely impact the commercialization
of  Gvoke,  Recorlev  and  Keveyis  and  the  launch  and  commercialization  of  our  product  candidates,  if  approved.  Even  if  we  are  able  to  recruit,  hire  and  retain  a  sufficient  number  of  sales
representatives, they may not be effective at promoting our products.

We intend to leverage the sales and marketing capabilities that we have established for our approved products to commercialize additional product candidates for the management of other conditions,
if approved by the FDA, in the United States. If we are unable to do so for any reason, we would need to expend additional resources to establish commercialization capabilities for those product
candidates, if approved. In the event that we are unable to effectively deploy our sales organization or distribution strategy on a timely and efficient basis, if at all, the commercialization of our
product candidates could be delayed which would negatively impact our ability to generate product revenue.

In addition, we intend to continue to establish collaborations to commercialize our product candidates outside the United States, if approved by the relevant regulatory authorities. Therefore, our
future  success  outside  the  United  States  will  depend,  in  part,  on  our  ability  to  enter  into  and  maintain  collaborative  relationships,  the  collaborator’s  strategic  interest  in  the  product  and  such
collaborator’s ability to successfully market and sell the product. We may not be able to establish or maintain such collaborative arrangements, or if

34

Table of Contents

we are able to do so, such collaborators may not have effective sales forces or exert the level of effort that we would if we were marketing and selling the product ourselves.

Risks Related to Third-Parties Actions and Market Acceptance

Our reliance on third-party suppliers, including single-source suppliers, together with a limited number of possible suppliers and long development lead-times for alternate sources for Gvoke,
Recorlev and Keveyis or our product candidates could harm our ability to develop our product candidates or to continue to commercialize Gvoke, Recorlev, Keveyis, or any product candidates
that are approved.

We do not currently own or operate any manufacturing facilities for the production of Gvoke, Recorlev, or Keveyis for commercial supply or our product candidates for use in clinical trials. We rely
on third-party suppliers to manufacture and supply our products and our product candidates. For Gvoke, we currently rely on a number of single-source suppliers, such as Bachem Americas, Inc. and
certain of its affiliates ("Bachem") for active pharmaceutical ingredient ("API"), Pyramid Laboratories Inc. ("Pyramid") for drug product and SHL Pharma, LLC ("SHL Pharma") for auto-injector and
final  product  assembly,  and  we  have  entered  into  several  supply  agreements  including  with  Bachem,  Pyramid  and  SHL  Pharma.  Taro  produces  all  of  our  requirements  for  Keveyis  pursuant  to  a
supply agreement. If the agreement were to be terminated by Taro prior to the next renewal in March of 2027, we will need to find a new third party to manufacture Keveyis or manufacture the
product ourselves. Similarly, for Recorlev, we rely on a number of single-source suppliers, such as Regis Technologies, Inc. for API and Xcelience, LLC ("Lonza") for finished drug product. We rely
on  other  third  parties  to  manufacture  our  product  candidates  for  use  in  clinical  trials.  If  any  of  these  vendors  are  unable  or  unwilling  to  meet  our  future  requirements,  we  may  not  be  able  to
manufacture and/or supply our products in a timely manner. Our current arrangements with these manufacturers are terminable by such manufacturers, subject to certain notice provisions. In addition,
Taro maintains certain reversion rights in the purchased assets, including the regulatory approval for Keveyis, enabling Taro to elect to have the purchased assets returned to it and to terminate its
agreement with us should we be materially in non-compliance with any reversion condition such as breaching certain of the assignment restrictions or failing to meet our marketing commitments after
receiving notice thereof and failing to cure such material non-compliance.

Our  third-party  suppliers  may  not  be  able  to  produce  sufficient  inventory  to  meet  commercial  demand  in  a  timely  manner,  or  at  all,  and  we  continue  to  experience  long  lead  times  for  certain
components and materials used in the production of our products and product candidates. Our third-party suppliers may not be required to provide us with any guaranteed minimum production levels
or have dedicated capacity for our products. As a result, we may not obtain sufficient quantities of products, components or other key materials in the future, which could have a material adverse
effect on our business as a whole. Any disruption to the facilities or operations of our third-party suppliers resulting from weather-related events, epidemics, including global health concerns, fire, acts
of terrorism, political instability, war, labor or geopolitical issues, or any other cause could materially impair our ability to manufacture our products and to distribute our products to customers. We
have a global supply chain and manufacture some components of our products outside the United States, including without limitation, Taiwan and Israel. The current war between Israel and Hamas
could directly and indirectly affect our operations. For example, the Israel-Hamas war could result in damage, destruction or disruptions to the facilities or operations of our third-party suppliers,
including, but not limited to, our supplier of Keveyis, longer lead times for ours products or product candidates, export delays or restrictions or other adverse events which adverse events we cannot
predict with any certainty. Any interruption or other delay in the production or delivery of our supplies could reduce sales of our products and increase our costs and any negative impact of such
matters on our third-party suppliers and manufacturers may also have an adverse impact on our results of operations or financial condition.

Gvoke and some of our product candidates are drug-device combination products that are regulated under the drug regulations of the Federal Food, Drug, & Cosmetic Act ("FDCA") based on their
primary  mode  of  action  as  a  drug.  Third-party  manufacturers  may  fail  to  comply  with  the  current  Good  Manufacturing  Practice  ("CGMP")  regulatory  requirements  applicable  to  drug-device
combination  products,  including  applicable  provisions  of  the  FDA’s  drug  CGMP  regulations,  device  CGMP  requirements  embodied  in  the  Quality  System  Regulation  (the  "QSR")  or  similar
regulatory requirements outside the United States. Our failure, or the failure of our third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us,
including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of our products and product candidates, re-labeling or
re-packaging of our products, operating restrictions and criminal prosecutions, any of which could significantly affect the supply of our products and product candidates. The facilities used by our
contract manufacturers to manufacture our products and product candidates must be registered with the FDA and are subject to inspections conducted by the FDA to ensure compliance with CGMPs.
Other foreign regulatory authorities may also require manufacturers to register manufacturing facilities. We do not control the manufacturing process of, and are completely dependent on, our contract
manufacturing  partners  for  compliance  with  CGMPs  and  the  QSR.  Contract  manufacturers  may  face  manufacturing  or  quality  control  problems  causing  drug  substance  or  device  component
production  and  shipment  delays  or  circumstances  where  the  contractor  may  not  be  able  to  maintain  compliance  with  the  applicable  CGMP  or  the  QSR.  If  our  contract  manufacturers  cannot
successfully  manufacture  material  that  conforms  to  our  specifications,  CGMP  and/or  the  QSR  and  the  strict  regulatory  requirements  of  the  FDA  or  others,  they  will  not  be  able  to  secure  and/or
maintain regulatory approval for their manufacturing facilities. In addition, we have no control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance
and qualified personnel. If the FDA or such foreign regulatory authorities do not approve these facilities for the manufacture of our products or product candidates or if they withdraw any such
approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to market our products or develop, obtain regulatory approval for or
market our product candidates, if approved.

35

There are a limited number of third-party suppliers that are compliant with CGMP and/or the QSR, as required by the FDA, the EU, and other regulatory authorities, and that also have the necessary
expertise and capacity to manufacture our materials and products. As a result, it may be difficult for us to locate third-party suppliers for our anticipated future needs, and our anticipated growth could
strain the ability of our current third-party suppliers to deliver products, raw materials, and components to us. If we are unable to arrange for third-party suppliers for our materials and products, or to
do so on commercially reasonable terms, we may not be able to complete development of or market our products.

The introduction of new CGMP or QSR regulations or product specific requirements by a regulatory body may require that we source alternative materials, modify existing manufacturing processes,
or implement design changes to our products that are subject to prior approval by the FDA or other regulatory authorities. We may also be required to reassess a third-party supplier’s compliance with
all applicable new regulations and guidelines, which could further impede our ability to manufacture and supply products in a timely manner. As a result, we could incur increased production costs,
experience supply interruptions, suffer damage to our reputation and experience an adverse effect on our business and financial results. On February 23, 2022, the FDA proposed to amend its Quality
System Regulation (“QSR”) requirements to align more closely with the international consensus standards for medical devices. Specifically, the FDA proposed to do so primarily by incorporating by
reference the 2016 edition of the International Organization of Standardization (“ISO”), ISO 13485 standard. We do not have certainty on when or if the proposed rule will be finalized or even if it is
finalized, whether it will be finalized in its current proposed form. While the ISO 13485 standard and the FDA’s QSR requirements are similar in certain aspects, it is possible that we may need to
revise our compliance system and processes to be in line with the requirements established by any final rule to amend the QSR requirements.

In addition, our reliance on third-party suppliers involves a number of additional risks, including, among other things:

















our suppliers may fail to comply with regulatory requirements or make errors in manufacturing raw materials, components or products that could negatively affect the efficacy or safety
of our products or cause delays in shipments of our products;
we may be subject to price fluctuations due to terms within long-term supply arrangements with suppliers or lack of long-term supply arrangements for key materials and products;
given the long lead times to change suppliers, existing suppliers may utilize that as leverage in negotiations with us in a manner that is adverse to our business;
our suppliers may lose access to critical services or sustain damage to a facility, including losses due to natural disasters, accidents, terrorism, geo-political events, or epidemics that may
result in a sustained interruption in the manufacture and supply of our products;
fluctuations in demand for our products or a supplier’s demand from other customers may affect their ability or willingness to deliver materials or products in a timely manner or may
lead to long-term capacity constraints at the supplier;
we may not be able to find new or alternative sources or reconfigure our products and manufacturing processes in a timely manner if necessary raw materials or components become
unavailable;
our suppliers may encounter financial or other hardships unrelated to our demand for materials, products and services, which could inhibit their ability to fulfill our orders and meet our
requirements; and
the possibility of breach or termination of a manufacturing agreement or purchase order by the third party.

In addition, we could be forced to secure new materials or develop alternative third-party suppliers, which can be difficult given our product complexity, long development lead-times and global
regulatory review processes.

36

Table of Contents

If any CMO with whom we contract fails to perform its obligations, we may be forced to enter into an agreement with a different CMO, which we may not be able to do on reasonable terms, if at all.
In either scenario, our clinical trials or commercial distribution could be delayed significantly as we establish alternative supply sources. In some cases, the technical skills required to manufacture our
products or product candidates may be unique or proprietary to the original CMO and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring such skills to a
back-up or alternate supplier, or we may be unable to transfer such skills at all. In addition, if we are required to change CMOs for any reason, we will be required to verify that the new CMO
maintains facilities and procedures that comply with quality standards and with all applicable regulations. We will also need to verify, such as through a manufacturing comparability study, that any
new manufacturing process will produce our product according to the specifications previously submitted to or approved by the FDA or another regulatory authority. The delays associated with the
verification of a new CMO could negatively affect our ability to develop product candidates or commercialize our products in a timely manner or within budget. Furthermore, a CMO may possess
technology related to the manufacture of our product candidate that such CMO owns independently. This would increase our reliance on such CMO or require us to obtain a license from such CMO
in order to have another CMO manufacture our products or product candidates which license we may not be able to obtain on favorable terms or at all. In addition, in the case of the CMOs that supply
our products or product candidates, changes in manufacturers often involve changes in manufacturing procedures and processes, which could require that we conduct bridging studies between our
prior clinical supply used in our clinical trials and that of any new manufacturer. We may be unsuccessful in demonstrating the comparability of clinical supplies which could require the conduct of
additional clinical trials. Additionally, under the CARES Act, we must have in place a risk management plan that identifies and evaluates the risks to the supply of approved drugs for certain serious
diseases or conditions for each establishment where the drug or API is manufactured. The risk management plan will be subject to FDA review during an inspection. If we experience shortages in the
supply of our marketed products, our results could be materially impacted.

Reimbursement decisions by third-party payors and consolidation within the healthcare industry and among competitors may have an adverse effect on pricing and market acceptance. If there is
not sufficient reimbursement for our products, it is less likely that they will be widely used and pricing pressure may impact our ability to sell our products at prices necessary to support our
current business strategies.

Our future revenues and profitability will be adversely affected if the United States and foreign governmental, private third-party insurers and payors and other third-party payors, including Medicare
and Medicaid, do not agree to defray or reimburse the cost of our products on behalf of patients. If these entities do not provide coverage and reimbursement with respect to our products or provide an
insufficient  level  of  coverage  and  reimbursement,  our  products  may  be  too  costly  for  some  patients  to  afford  and  physicians  may  not  prescribe  them.  In  addition,  limitations  on  the  amount  of
reimbursement for our products may also reduce our profitability. In the United States and some foreign jurisdictions, there have been, and we expect there will continue to be, actions and proposals
to control and reduce healthcare costs. There have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing
approval  for  our  product  candidates,  restrict  or  regulate  post-approval  activities  and  affect  our  ability  to  profitably  sell  any  of  our  products  or  product  candidates  for  which  we  obtain  marketing
approval. As the healthcare industry consolidates, competition to provide products and services to industry participants has become more intense and may intensify as the potential purchasers of our
products or third-party payors use their purchasing power to exert competitive pricing pressure and other terms favorable to them. We expect that market demand, government regulation, third-party
coverage and reimbursement policies and societal pressures will continue to change the healthcare industry worldwide, resulting in further business consolidations and alliances among our potential
purchasers. If competitive or other forces drive down the prices we are able to charge for our products, our profit margins will shrink, which will adversely affect our ability to invest in and grow our
business. For more information, see the sections entitled, "Business — Coverage and Reimbursement" and "Business — Healthcare Reform".

Government and other third-party payors are also challenging the prices charged for healthcare products and increasingly limiting, and attempting to limit, both coverage and level of reimbursement
for prescription drugs.

There is also significant uncertainty related to the insurance coverage and reimbursement of newly approved products, and coverage may be more limited than the purposes for which the medicine is
approved  by  the  FDA  or  comparable  foreign  regulatory  authorities.  In  the  United  States,  the  principal  decisions  about  reimbursement  for  new  medicines  are  typically  made  by  the  Centers  for
Medicare & Medicaid Services, or CMS, an agency within the United States Department of Health and Human Services. CMS decides whether and to what extent a new medicine will be covered and
reimbursed under Medicare, and private payors tend to follow CMS to a substantial degree.

New requirements by third-party payors include: (i) net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any
future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States and (ii) third-party payors are increasingly requiring
that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that reimbursement will be available
for  any  product  candidate  that  we  commercialize  and,  if  reimbursement  is  available,  the  level  of  reimbursement;  and  many  pharmaceutical  manufacturers  must  calculate  and  report  certain  price
metrics to the government, such as average manufacturer price, or AMP, and Best Price. Penalties may apply when such metrics are not submitted accurately and timely. Further, these prices for drugs
may be reduced by mandatory discounts or rebates required by government healthcare programs.

The  United  States  and  several  other  jurisdictions  are  considering,  or  have  already  enacted,  a  number  of  legislative  and  regulatory  proposals  to  change  the  healthcare  system  in  ways  that  could
negatively  affect  our  ability  to  sell  our  products  profitably.  Among  policy  makers  and  payors  in  the  United  States  and  elsewhere,  there  is  significant  interest  in  promoting  changes  in  healthcare
systems

37

Table of Contents

with the stated goals of containing healthcare costs, improving quality and/or expanding access to healthcare. In the United States, the pharmaceutical industry has been a particular focus of these
efforts and has been significantly affected by major legislative initiatives. We expect to experience pricing pressures in connection with the sale of our products that we develop due to the trend
toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative proposals.

At  the  state  level,  legislatures  have  increasingly  passed  legislation  and  implemented  regulations  designed  to  control  pharmaceutical  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.

Adoption of general controls and measures, coupled with the tightening of restrictive policies in jurisdictions with existing controls and measures, could limit payments for pharmaceutical drugs.
While  we  cannot  predict  what  impact  on  federal  reimbursement  policies  this  legislation  will  have  in  general  or  on  our  business  specifically,  these  factors  may  result  in  downward  pressure  on
pharmaceutical reimbursement, which could negatively affect market acceptance of our products and our product candidates.

Some patients may require health insurance coverage to afford our products or product candidates, and if we are unable to obtain adequate coverage and reimbursement by third-party payors, our
ability  to  successfully  commercialize  our  products  or  product  candidates  may  be  adversely  impacted.  Any  limitation  on  the  use  of  our  products  or  any  decrease  in  the  price,  including  through
increased discounting, of our products will have a material adverse effect on our ability to achieve profitability.

The success of Gvoke, Recorlev, Keveyis and our product candidates will be dependent on their proper use by patients, healthcare practitioners and caregivers. Additionally, individual devices
may fail.

We  have  designed  our  products  to  be  operable  by  patients,  caregivers,  and  healthcare  practitioners.  We  cannot  control  the  successful  use  of  the  product  by  patients,  caregivers,  and  healthcare
practitioners. If we are not successful in promoting the proper use of our products by patients, healthcare practitioners, and caregivers, we may not be able to achieve market acceptance or effectively
commercialize our products. In addition, even in the event of proper use of our products such as Gvoke, individual devices may fail. Increasing the scale of production inherently creates increased
risk  of  manufacturing  errors,  and  we  may  not  be  able  to  adequately  inspect  every  tablet  or  device  that  is  produced,  and  it  is  possible  that  individual  product  may  fail  to  perform  as  designed.
Manufacturing errors could negatively impact market acceptance of any of our products, result in negative press coverage, or increase the risk that we may be sued.

A small number of major customers account for a high percentage of our revenue, thus, the loss of any of these customers and our inability to enter into new customer relationships could
negatively impact our business.

We depend on a relatively small number of customers for the majority of our revenue. As further discussed in "Note 2 - Basis of presentation and summary of significant accounting policies and
estimates" to our consolidated financial statements, for the years ended December 31, 2023, 2022 and 2021, four customers accounted for over 90% of the Company’s gross product revenue. At
December 31, 2023 and December 31, 2022, the same four customers accounted for over 90% of the trade accounts receivable, net. We expect to continue to depend upon a relatively small number of
customers for a high percentage of our revenue. If we lose any of these customers and are unable to establish new customer relationships of similar magnitude, our business, prospects, financial
condition and results of operations could be materially and adversely affected. Additionally, if one or more of our major customers experiences financial difficulties, the adverse impact on us could be
substantial.

Risk Related to our Dependence on Third Parties for Clinical Trials

We  depend  on  third  parties  to  conduct  the  clinical  trials  for  our  product  candidates,  and  any  failure  of  those  parties  to  fulfill  their  obligations  could  harm  our  development  and
commercialization plans.

We depend on independent clinical investigators, clinical research organizations ("CROs"), academic institutions and other third-party service providers to conduct clinical trials with and for our
product candidates. Although we rely heavily on these parties for successful execution of our clinical trials, we are ultimately responsible for the results of their activities and many aspects of their
activities are beyond our control. Third parties may not complete activities on schedule or may not conduct our clinical trials in accordance with regulatory requirements or our stated protocols. For
example,  we  are  responsible  for  ensuring  that  each  of  our  clinical  trials  is  conducted  in  accordance  with  the  general  investigational  plan  and  protocols  for  the  trial,  but  the  independent  clinical
investigators may prioritize other projects over ours or may fail to timely communicate issues regarding our products to us. Further, conducting clinical trials in foreign countries, as we have done and
may do for certain of our product candidates, presents additional risks that may delay completion of our clinical trials. These risks include the failure of enrolled patients in foreign countries to adhere
to clinical protocol as a result of differences in healthcare services or cultural customs, managing additional administrative burdens associated with foreign regulatory schemes, as well as political and
economic risks relevant to such foreign countries. The delay or early termination of any of our clinical trial arrangements, the failure of third parties to comply with the regulations and requirements
governing clinical trials, or our reliance on results of trials that we have not directly conducted or monitored could hinder or delay the development, approval and commercialization of our product
candidates and would adversely affect our business, results of operations and financial condition.

We maintain compliance programs related to our clinical trials through our clinical operations and development personnel. Our clinical trial vendors are required to monitor and report to us issues
with the conduct of our clinical trials, and we monitor our clinical trial vendors through our clinical, regulatory, and quality assurance staff and other service providers. Our clinical trial vendors or

38

Table of Contents

personnel may not timely and fully discover and report any fraud or abuse or other issues that may occur in connection with our clinical trials to us. Such fraud or abuse or other issues, if they occur
and are not successfully remediated, could have a material adverse effect on our research, development, and commercialization activities and results.

Risks Related to the Product Development and Regulatory Approval of Our Product Candidates

Risks Related to Regulatory Approval

We cannot be certain that our product candidates will receive marketing approval. Without marketing approval, we will not be able to commercialize our product candidates.

We have devoted significant financial resources and business efforts to the development of our product candidates. We cannot be certain that any of our product candidates will receive marketing
approval.

The development of a product candidate and issues relating to its approval and marketing are subject to extensive regulation by the FDA and other regulatory authorities in the United States and by
comparable regulatory authorities in other countries. We are not permitted to market our product candidates in the United States until we receive approval of a New Drug Application ("NDA") or
Biologics License Application ("BLA") from the FDA. The time required to obtain approval by the FDA and comparable foreign authorities is unpredictable but typically takes many years following
the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatory authorities. In addition, conditions for approval, regulations, standards
of care, or the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions.

NDAs and BLAs must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and effectiveness for each desired indication. NDAs and
BLAs must also include significant information regarding the chemistry, manufacturing and controls for the product. Obtaining approval of an NDA or BLA is a lengthy, expensive and uncertain
process, and we may not be successful in obtaining approval. Any delay or setback in the regulatory approval or commercialization of any of our product candidates will adversely affect our business.

The FDA has substantial discretion in the drug approval process, including the ability to delay, limit or deny approval of a product candidate for many reasons. For example, the FDA:



















could determine that we cannot rely on the Section 505(b)(2) regulatory pathway or other pathways we have selected, as applicable, for our product candidates;
could  determine  that  the  information  provided  by  us  was  inadequate,  contained  clinical  deficiencies  or  otherwise  failed  to  demonstrate  the  safety  and  effectiveness  of  our  product
candidates for any indication;
may not find the data from bioequivalence studies and/or clinical trials sufficient to support the submission of an NDA or to obtain marketing approval, including any findings that the
clinical and other benefits of our product candidates do not outweigh their safety risks;
may disagree with our trial design or our interpretation of data from preclinical studies, bioequivalence studies and/or clinical trials, or may change the requirements for approval even
after it has reviewed and commented on the design for our trials;
may determine that we have identified the wrong listed drug or drugs or that approval of our Section 505(b)(2) application for any of our product candidates is blocked by patent or non-
patent exclusivity of the listed drug or drugs or of other previously approved drugs with the same conditions of approval as any of our product candidates (as applicable);
may identify deficiencies in the manufacturing processes or facilities of third-party manufacturers with which we enter into agreements for the manufacturing of our product candidates;
may audit some or all of our clinical research and human factors study sites to determine the integrity of our data and may reject any or all of such data;
may approve our product candidates for fewer or more limited indications than we request, or may grant approval contingent on the performance of costly post-approval clinical trials or
implementation of a REMS;
may change its criteria for approval, policies or adopt new regulations; or
may not approve the labeling claims that we believe are necessary or desirable for the successful commercialization of our product candidates.

Even  if  a  product  is  approved,  the  FDA  may  limit  the  indications  for  which  the  product  may  be  marketed,  require  extensive  warnings  on  the  product  labeling  (e.g.,  boxed  warnings)  or  require
expensive and time-consuming clinical trials and/or reporting as conditions of approval. Regulators in other countries and jurisdictions have their own procedures for approval of product candidates
with which we must comply prior to marketing in those countries or jurisdictions.

Obtaining regulatory approval for marketing of a product candidate in one country does not ensure that we will be able to obtain regulatory approval in any other country. In addition, delays in
approvals  or  rejections  of  marketing  applications  in  the  United  States  or  other  countries  may  be  based  upon  many  factors,  including  regulatory  requests  for  additional  analyses,  reports,  data,
preclinical studies and clinical trials, regulatory questions regarding different interpretations of data and results, changes in regulatory policy

39

Table of Contents

during the period of product development and the emergence of new information regarding our product candidates or other products. Also, regulatory approval for any of our product candidates may
be withdrawn.

Clinical failure may occur at any stage of clinical development, and the results of our clinical trials may not support our proposed indications for our product candidates. If our clinical trials fail
to demonstrate efficacy and safety to the satisfaction of the FDA or other regulatory authorities, we may incur additional costs or experience delays in completing, or ultimately be unable to
complete, the development of such product candidates.

We cannot be certain that existing clinical trial results will be sufficient to support regulatory approval of our product candidates. Success in preclinical testing and early clinical trials does not ensure
that later clinical trials will be successful, and we cannot be sure that the results of later clinical trials will replicate the results of prior clinical trials and preclinical testing. Moreover, success in
clinical trials in a particular indication does not ensure that a product candidate will be successful in other indications. A number of companies in the pharmaceutical industry have suffered significant
setbacks in clinical trials, even after promising results in earlier preclinical studies or clinical trials or successful later-stage trials in other related indications. These setbacks have been caused by,
among other things, preclinical findings made while clinical trials were underway and safety or efficacy observations made in clinical trials, including previously unreported adverse events. The
results of preclinical and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Product candidates in later stages of clinical trials may fail to
show the desired safety and efficacy traits despite having progressed through preclinical and initial clinical trials. A failure of a clinical trial to meet its predetermined endpoints would likely cause us
to abandon a product candidate and may delay development of any of our product candidates. Any delay in, or termination of, our clinical trials will delay the submission of the applicable NDA or
BLA to the FDA, the Marketing Authorisation Application ("MAA") to the European Medicines Agency ("EMA") or other similar applications with other relevant foreign regulatory authorities and,
ultimately, our ability to commercialize our product candidates and generate revenue.

We intend to utilize the 505(b)(2) pathway for the regulatory approval of certain of our product candidates. If the FDA does not conclude that such product candidates meet the requirements of
Section 505(b)(2), final marketing approval of our product candidates by the FDA or other regulatory authorities may be delayed, limited, or denied, any of which would adversely affect our
ability to generate operating revenues.

We are pursuing a regulatory pathway pursuant to Section 505(b)(2) of the FDCA for the approval of certain of our product candidates, which allows us to rely on submissions of existing clinical data
for the drug. Section 505(b)(2) was enacted as part of the Drug Price Competition and Patent Term Restoration Act of 1984, or the Hatch-Waxman Amendments, and permits the submission of an
NDA where at least some of the information required for approval comes from preclinical studies or clinical trials not conducted by or for the applicant and for which the applicant has not obtained a
right of reference. The FDA interprets Section 505(b)(2) of the FDCA to permit the applicant to rely upon the FDA’s previous findings of safety and efficacy for an approved product. The FDA
requires submission of information needed to support any changes to a previously approved drug, such as published data or new studies conducted by the applicant or clinical trials demonstrating
safety and efficacy. The FDA could require additional information to sufficiently demonstrate safety and efficacy to support approval.

If the FDA determines that our product candidates do not meet the requirements of Section 505(b)(2), we may need to conduct additional clinical trials, provide additional data and information, and
meet additional standards for regulatory approval. In March 2010, former President Obama signed into law legislation creating an abbreviated pathway for approval under the Public Health Service
Act, or PHS Act, of biological products that are similar to other biological products that are approved under the PHS Act. The legislation also expanded the definition of biological product to include
proteins such as insulin. The law contains transitional provisions governing protein products such as insulin, that, under certain circumstances, might permit companies to seek approval for their
insulin products as biologics under the PHS Act. Specifically, on March 23, 2020, a small subset of "biological products" approved under the FDCA, such as insulin, which historically were approved
as drugs, transitioned to being regulated as biological products. Being regulated as biological products enables transition products to serve as the reference product for biosimilar or interchangeable
products approved through the abbreviated licensure pathway. The transition is a regulatory action in which the approved drug application for a transition biological product will be "deemed" to be a
biologics license application. If our other product candidates do not meet the requirements of Section 505(b)(2) or are otherwise ineligible or become ineligible for approval via the Section 505(b)(2)
pathway,  the  time  and  financial  resources  required  to  obtain  FDA  approval  for  these  product  candidates,  and  the  complications  and  risks  associated  with  these  product  candidates,  would  likely
substantially increase. Moreover, an inability to pursue the Section 505(b)(2) regulatory pathway would likely result in new competitive products reaching the market more quickly than our product
candidates, which would likely materially adversely impact our competitive position and prospects. Even if we are allowed to pursue the Section 505(b)(2) regulatory pathway, our product candidates
may not receive the requisite approvals for commercialization.

Some pharmaceutical companies and other actors have objected to the FDA’s interpretation of Section 505(b)(2) to allow reliance on the FDA’s prior findings of safety and effectiveness. If the FDA
changes its interpretation of Section 505(b)(2), or if the FDA’s interpretation is successfully challenged in court, this could delay or even prevent the FDA from approving any Section 505(b)(2)
application that we submit. Moreover, the FDA has adopted an interpretation of the three-year exclusivity provisions whereby a 505(b)(2) application can be blocked by exclusivity even if it does not
rely on the previously approved drug that has exclusivity (or any safety or effectiveness information regarding that drug). Under the FDA’s interpretation, the approval of one or more of our

40

Table of Contents

product candidates may be blocked by exclusivity awarded to a previously-approved drug product that shares certain innovative features with our product candidates, even if our 505(b)(2) application
does not identify the previously-approved drug product as a listed drug or rely upon any of its safety or efficacy data. Any failure to obtain regulatory approval of our product candidates would
significantly limit our ability to generate revenues, and any failure to obtain such approval for all of the indications and labeling claims we deem desirable could reduce our potential revenues.

Additional time may be required to obtain regulatory approval for certain of our product candidates because they are combination products.

Certain of our product candidates are drug and device combination products that require coordination within the FDA and similar foreign regulatory agencies for review of their device and drug
components.  Medical  products  containing  a  combination  of  new  drugs,  biological  products  or  medical  devices  may  be  regulated  as  "combination  products"  in  the  United  States  and  Europe.  A
combination  product  generally  is  defined  as  a  product  comprised  of  components  from  two  or  more  regulatory  categories  (e.g.,  drug/device,  device/biologic,  drug/biologic).  Each  component  of  a
combination product is subject to the requirements established by the FDA for that type of component, whether a new drug, biologic or device. In order to facilitate pre-market review of combination
products, the FDA designates one of its centers to have primary jurisdiction for the pre-market review and regulation of the overall product based upon a determination by the FDA of the primary
mode of action of the combination product. Where approval of the drug and device is sought under a single application, there could be delays in the approval process due to the increased complexity
of the review process and the lack of a well-established review process and criteria. The EMA has a parallel review process in place for combination products, the potential effects of which in terms
of approval and timing could independently affect our ability to market our combination products in Europe.

Gvoke, Recorlev, Keveyis and our product candidates may have undesirable side effects which may delay or prevent marketing approval, or, if approval is received, require them to include safety
warnings, require them to be taken off the market or otherwise limit their sales.

Patients treated in clinical trials with our ready-to-use glucagon have experienced drug-related side effects typically observed with glucagon products, including nausea, vomiting and headaches. In
our clinical trials of Recorlev, the most common adverse reactions (incidence > 20%) were nausea/vomiting, hypokalemia, hemorrhage/contusion, systemic hypertension, headache, hepatic injury,
abnormal uterine bleeding, erythema, fatigue, abdominal pain/dyspepsia, arthritis, upper respiratory infection, myalgia, arrhythmia, back pain, insomnia/sleep disturbances, and peripheral edema. In
the Keveyis clinical trial, the most common adverse reactions (incidence > 10%) were paresthesia, cognitive disorder, dysgeusia, and confusional state. These adverse events can be dose-dependent
and may increase in frequency and severity if we increase the dose to increase efficacy.

For our product candidates in development, undesirable side effects that may be caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials, and
result in delay of, or failure to obtain, marketing approval from the FDA and other regulatory authorities, or result in marketing approval from the FDA and other regulatory authorities with restrictive
label warnings, and for our approved products, the emergence of new or more serious side effects may cause regulatory authorities to impose additional requirements on our marketing and monitoring
of these products. The range and potential severity of possible side effects from systemic therapies are significant. Recent developments in the pharmaceutical industry have prompted heightened
government  focus  on  safety  reporting  during  both  pre-  and  post-approval  time  periods  and  pharmacovigilance.  For  example,  at  the  request  of  the  FDA  we  are  conducting  an  enhanced
pharmacovigilance program for all cases of hepatotoxicity reported with patients taking Recorlev tablets, for a period of 5 years from the date of approval. Global health authorities may impose
regulatory  requirements  to  monitor  safety  that  may  burden  our  ability  to  commercialize  our  drug  products.  In  addition,  drug-related  side  effects  of  our  product  candidates  could  affect  patient
recruitment or the ability of enrolled patients to complete the trial or could also adversely affect physician or patient acceptance thereof. Any of these occurrences may harm our business, financial
condition and prospects.

Even if our product candidates receive marketing approval, if we or others later identify undesirable or unacceptable side effects caused by one of our products:

  regulatory authorities may require the addition of labeling statements, including "black box" warnings, contraindications or dissemination of field alerts to physicians and pharmacies;

we may be required to change instructions regarding the way the product is administered, conduct additional clinical trials or change the labeling of the product;
we may be subject to limitations on how we may promote the product;
sales of the product may decrease significantly;
regulatory authorities may require us to take our approved product off the market;
we may be subject to litigation or products liability claims; and
our reputation may suffer.

Any of these events could also prevent us from achieving or maintaining market acceptance of the affected product or could substantially increase commercialization costs and expenses, which in
turn could delay or prevent us from generating significant revenues from the sale of our products.

We have received orphan drug designation for Keveyis, Recorlev and certain of our product candidates with respect to certain indications and may pursue such designation for others, but we
may be unable to obtain such designation or to maintain the benefits associated with orphan drug status, including market exclusivity, even if that designation is granted.

We have received orphan drug designation from the FDA for five indications for our products and product candidates, which are our ready-to-use glucagon for post-bariatric hypoglycemia ("PBH")
and Congenital Hyperinsulinism ("CHI"), and for Recorlev, for the treatment of adult patients with endogenous Cushing’s syndrome for whom surgery is not an option or has not been curative. We
may pursue such designation for others in specific orphan indications in which there is an unmet medical need. We relied on orphan drug exclusivity in the marketing and sale of Keveyis until it
expired on August 7, 2022 and with respect to the marketing and sale of Recorlev, intend to rely on orphan drug exclusivity through December 30, 2028. Under the Orphan Drug Act of 1983, the
FDA  may  designate  a  product  candidate  as  an  orphan  drug  if  it  is  intended  to  treat  a  rare  disease  or  condition,  which  is  generally  defined  as  having  a  patient  population  of  fewer  than  200,000
individuals in the United States, or a patient population greater than 200,000 in the United States where there is no reasonable expectation that the cost of developing the drug will be recovered from
sales in the United States. Orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-fee waivers.
After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage
in, or shorten the duration of, the regulatory review and approval process. Although we may seek orphan drug designation for certain additional indications, we may never receive such designation.
Moreover, obtaining orphan drug designation for one indication does not mean we will be able to obtain such designation for another indication.

If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to
orphan drug exclusivity. Orphan drug exclusivity means that the FDA may not approve any other applications, including an NDA, to market the same drug for the same indication for seven years,
except in limited circumstances such as if the FDA finds that the holder of the orphan drug exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan drug to
meet the needs of patients with the disease or condition for which the drug was designated. Similarly, the FDA can subsequently approve a drug with the same active moiety for the same condition
during the exclusivity period if the FDA concludes that the later drug is clinically superior, meaning the later drug is safer, more effective or makes a major contribution to patient care. In assessing
whether a drug provides a "major contribution to patient care" over and above the currently approved drugs, which is evaluated by the FDA on a case-by-case basis, there is no one objective standard
and the FDA may, in appropriate circumstances, consider such factors as convenience of treatment location, duration of treatment, patient comfort, reduced treatment burden, advances in ease and
comfort of drug administration, longer periods between doses, and potential for self-administration. However, such a demonstration to overcome the seven-year market exclusivity may be difficult to
establish  with  limited  precedents  and  there  can  be  no  assurance  that  we  will  be  successful  in  these  efforts  if  and  where  we  pursue  them.  Even  with  respect  to  the  indications  for  which  we  have
received orphan designation, we may not be the first to obtain marketing approval for any particular orphan indication due to the uncertainties associated with developing pharmaceutical products,
and thus approval of our product candidates could be blocked for seven years if another company previously obtained approval and orphan drug exclusivity for the same drug and same condition. If
we do obtain exclusive marketing rights in the United States, they may be limited if we seek approval for an indication broader than the orphan designated indication and may be lost if the FDA later
determines that the request for designation was materially defective or if we are unable to assure sufficient quantities of the product to meet the needs of the relevant patients. Further, exclusivity may
not  effectively  protect  the  product  from  competition  because  different  drugs  with  different  active  moieties  can  be  approved  for  the  same  condition,  the  same  drugs  can  be  approved  for  different
indications and might then be used off-label in our approved indication, and different drugs for the same condition may already be approved and commercially available.

In  the  European  Union,  the  period  of  orphan  market  exclusivity  is  ten  years,  although  it  may  be  reduced  to  six  years  if,  at  the  end  of  the  fifth  year,  it  is  established  that  the  criteria  for  orphan
designation are no longer met, including if it is shown on the basis of

42

Table of Contents

available evidence that the product is sufficiently profitable not to justify maintenance of market exclusivity. Legislation has been proposed by the European Commission that, if implemented, has the
potential in some cases to shorten the ten-year period of orphan market exclusivity. We have received orphan designation from the EMA for our ready-to-use glucagon for the treatment of CHI and
NIPHS, which includes patients with PBH.

Even with the FDA approval of Gvoke, Recorlev and Keveyis in the United States, and the EMA and MHRA approval of Ogluo in the European Union ("EU") and the United Kingdom ("UK"),
we may not be able to obtain or maintain foreign regulatory approvals to market our products in other countries.

We do not have any products other than Gvoke, Recorlev, and Keveyis approved for sale in the United States, nor any products or product candidates other than Ogluo approved for sale in any
international markets, and we do not have experience in obtaining regulatory approval in international markets outside of the EU and the UK. In order to market products in any particular jurisdiction,
we must establish and comply with numerous and varying regulatory requirements on a country-by-country basis regarding safety and efficacy. Approval by the FDA in the United States does not
ensure approval by regulatory authorities in other countries or jurisdictions, and approval or certification by one foreign regulatory authority does not ensure approval or certification by regulatory
authorities  in  other  foreign  countries  or  by  the  FDA.  International  jurisdictions  require  separate  regulatory  approvals  and  compliance  with  numerous  and  varying  regulatory  requirements.  The
approval procedures vary among countries and may involve requirements for additional testing, and the time required to obtain approval may differ from country to country and from that required to
obtain clearance or approval in the United States.

In addition, some countries only approve or certify a product for a certain period of time, and we are required to re-approve or re-certify our products in a timely manner prior to the expiration of our
prior approval or certification. We may not obtain foreign regulatory approvals on a timely basis, if at all. We may not be able to file for regulatory approvals or certifications and may not receive
necessary approvals to commercialize our products in any market. If we fail to receive necessary approvals or certifications to commercialize our products in foreign jurisdictions on a timely basis, or
at  all,  or  if  we  fail  to  have  our  products  re-approved  or  re-certified,  our  business,  results  of  operations  and  financial  condition  could  be  adversely  affected.  The  foreign  regulatory  approval  or
certification  process  may  include  all  of  the  risks  associated  with  obtaining  FDA  clearance  or  approval.  In  addition,  the  clinical  standards  of  care  may  differ  significantly  such  that  clinical  trials
conducted  in  one  country  may  not  be  accepted  by  healthcare  providers,  third-party  payors  or  regulatory  authorities  in  other  countries,  and  regulatory  approval  in  one  country  does  not  guarantee
regulatory  approval  in  any  other  country.  If  we  fail  to  comply  with  regulatory  requirements  in  international  markets  or  to  obtain  and  maintain  required  approvals,  or  if  regulatory  approvals  in
international markets are delayed, our target market will be reduced and our ability to realize the full market potential of any drug we develop will be unrealized.

Recently enacted and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize our products and product candidates and affect the prices
we may obtain.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay
regulatory approval of our product candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any products or product candidates for which we obtain marketing
approval. For more information, see the section entitled, "Business — Healthcare Reform".

The cost of prescription pharmaceuticals in the United States has also been the subject of considerable debate, and members of Congress have indicated that they will address such costs through new
legislative measures. To date, there have been several recent United States congressional inquiries and proposed state and federal legislation designed to, among other things, improve transparency in
drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the costs of drugs under Medicare, and reform government program reimbursement methodologies
for drug products. There has recently been intense publicity regarding the pricing of pharmaceutical products generally, including publicity and pressure resulting from the prices charged for new
products as well as price increases for older products that the government and public deem excessive. We may experience downward pricing pressure on the price of our products due to social or
political  pressure  to  lower  the  cost  of  drugs,  which  could  reduce  our  revenue  and  future  profitability.  Many  companies  in  our  industry  have  received  governmental  requests  for  documents  and
information relating to drug pricing and patient support programs. We could incur significant expense and experience reputational harm as a result of these or other similar future inquiries, as well as
reduced market acceptance and demand for our products, which could harm our ability to market our products in the future. These factors could also result in changes in our product pricing and
distribution strategies, reduced demand for our products and/or reduced reimbursement of products, including by federal health care programs such as Medicare and Medicaid and state health care
programs.

We cannot predict the initiatives that may be adopted in the future. The continuing efforts of the government, insurance companies, managed care organizations and other payors of healthcare services
to contain or reduce costs of healthcare and/or impose price controls may adversely affect:

43

Table of Contents

  the demand for our product candidates, if we obtain regulatory approval;
our ability to set a price that we believe is fair for our approved products;
our ability to generate revenue and achieve or maintain profitability;
the level of taxes that we are required to pay; and
the availability of capital.

The pricing of prescription pharmaceuticals is also subject to governmental control outside the United States. In these other countries, pricing negotiations with governmental authorities can take
considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a clinical trial that compares
the cost effectiveness of our product candidates to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels,
our ability to generate revenues and become profitable could be impaired.

Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for approved products. In addition, there have been several
recent  Congressional  inquiries  and  proposed  bills  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.  We  cannot  be  sure  whether  additional  legislative  changes  will  be
enacted, or whether the FDA regulations, guidance or interpretations will be changed, or what the impact of such changes on the marketing approvals of our products and product candidates, if any,
may be. In addition, increased scrutiny by the United States Congress of the FDA’s approval process may significantly delay or prevent marketing approval of those product candidates for which we
seek marketing approval, as well as subject us to more stringent labeling and post-marketing testing and other requirements.

Risks Related to our Industry and Ongoing Legal and Regulatory Requirements

Risks Related to Ongoing Regulatory Obligations

Even after approval of our products and product candidates, we may still face future development and regulatory difficulties. If we fail to comply with continuing United States and non-United
States regulations or new adverse safety data arise, we could lose our marketing approvals and our business would be seriously harmed.

Our approved products and product candidates, if approved, will also be subject to ongoing regulatory requirements for manufacturing, distribution, sale, labeling, packaging, storage, advertising,
promotion,  record-keeping  and  submission  of  safety  and  other  post-market  information.  Approved  products,  third-party  suppliers  and  their  facilities  are  required  to  comply  with  extensive  FDA
requirements and requirements of other regulatory authorities even after approval, including ensuring that quality control and manufacturing procedures conform to CGMPs and applicable QSRs and
applicable product tracking and tracing requirements. As such, we and our third-party suppliers are subject to continual review and periodic inspections, both announced and unannounced, to assess
compliance with CGMPs and the QSR. Accordingly, we and our third-party suppliers must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing,
production and quality control. We will also be required to report certain adverse events and production problems, if any, to the FDA and other regulatory authorities and to comply with certain
requirements concerning advertising and promotion of our products. Promotional communications with respect to prescription drugs are subject to a variety of legal and regulatory restrictions and
must be consistent with the information in the product’s approved label. Accordingly, we may not promote our approved products for indications or uses for which they are not approved.

If  a  regulatory  agency  discovers  previously  unknown  problems  with  a  product,  such  as  adverse  events  of  unanticipated  severity  or  frequency,  or  problems  with  the  facility  where  the  product  is
manufactured, or disagrees with the promotion, marketing or labeling of a product, it may impose restrictions on that product or us, including requiring withdrawal of the product from the market.
These unknown problems could be discovered as a result of any post-marketing follow-up studies, routine safety surveillance or other reporting required as a condition to approval.

Regulatory agencies may also impose requirements for costly post-marketing studies or clinical trials and surveillance to monitor the safety or efficacy of a product. Additionally, under FDORA,
sponsors of approved drugs and biologics must provide 6 months’ notice to the FDA of any changes in marketing status, such as the withdrawal of a drug, and failure to do so could result in the FDA
placing the product on a list of discontinued products, which would revoke the product’s ability to be marketed. The FDA, the Federal Trade Commission and other agencies and government entities,
including the Department of Justice ("DOJ") and the Office of Inspector General of the United States Department of Health and Human Services, 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.
The FDA imposes stringent restrictions on manufacturers’ communications regarding off-label use, and if we, or any future collaborators, do not market any of our products for which we, or they,
receive  marketing  approval  for  only  their  approved  indications,  we,  or  they,  may  be  subject  to  warning  or  enforcement  action  for  off-label  marketing,  government  investigations,  or  litigation.
Violation of the FDCA and other statutes, including the False Claims Act, relating to the promotion and advertising of prescription drugs may lead to investigations or allegations of violations of
federal and state healthcare fraud and abuse laws and state consumer protection laws. On June 7, 2023, we received an untitled letter from FDA’s Office of Prescription Drug Promotion ("OPDP")
regarding specific sections of the Recorlev consumer website. The letter raised concerns that the webpages made false or misleading claims about the safety and efficacy of Recorlev that misbrand
Recorlev within the meaning of the FDCA. We submitted a response to the FDA regarding our plan to revise those sections of the webpages at issue.

44

Table of Contents

The FDA completed evaluation of our response and issued a close-out letter in August 2023 stating that it appears that we have addressed all the concerns contained in the untitled letter.

If our products or product candidates fail to comply with applicable regulatory requirements, or if a problem with one of our products or third-party suppliers is discovered, a regulatory agency may:

   restrict the marketing or manufacturing of such products;










restrict or require modification of or revision to the labeling of a product;
issue warning letters or untitled letters which may require corrective action;
mandate modifications to promotional materials or require us to provide corrective information to healthcare practitioners;
require  us  to  enter  into  a  consent  decree  or  permanent  injunction,  which  can  include  imposition  of  various  fines,  reimbursements  for  third  party  inspection  and/or  monitoring  costs,
corrective action plans with required due dates for specific actions and penalties for noncompliance;
impose other administrative or judicial civil or criminal penalties including fines, imprisonment and disgorgement of profits;
suspend or withdraw regulatory approval;
refuse to approve pending applications or supplements to approved applications filed by us;
close the facilities of our third-party suppliers;
suspend ongoing clinical trials;
impose restrictions on operations, including costly new manufacturing requirements; or
seize or detain products or recommend or require a product recall.

The FDA’s and foreign regulatory agencies’ policies are subject to change, and additional federal, state, local or non-United States governmental regulations may be enacted that could affect our
ability to maintain compliance. We cannot predict the likelihood, nature or extent of adverse governmental regulation that may arise from future legislation or administrative action, either in the
United States or abroad.

Our relationships with customers and payors are subject to applicable anti-kickback, fraud and abuse, transparency, privacy, and other healthcare laws and regulations, which could expose us
to criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors play a primary role in the recommendation and prescription use of any products for which we obtain marketing approval. Our arrangements
with investigators, healthcare practitioners, consultants, third-party payors and customers, if any, will subject us to broadly applicable fraud and abuse and other healthcare laws and regulations. These
laws and regulations may constrain the business or financial arrangements and relationships through which we conduct our operations, including how we research, market, sell and distribute any
products for which we obtain marketing approval. For more information, see the section entitled, "Business — Other Healthcare Laws and Compliance Requirements".

Efforts to ensure that our business arrangements with third parties, and our business generally, comply with applicable healthcare laws and regulations involve substantial costs. It is possible that
governmental  authorities  will  conclude  that  our  business  practices,  including  our  arrangements  with  physicians  and  other  healthcare  providers,  some  of  whom  may  receive  stock  options  as
compensation  for  services  provided,  may  not  comply  with  current  or  future  statutes,  regulations,  agency  guidance  or  case  law  involving  applicable  fraud  and  abuse  or  other  healthcare  laws  and
regulations.  If  our  operations  are  found  to  be  in  violation  of  any  of  these  laws  or  any  other  governmental  regulations  that  may  apply  to  us,  we  may  be  subject  to  significant  civil,  criminal  and
administrative penalties, damages, fines, imprisonment, exclusion of products from government funded healthcare programs, such as Medicare and Medicaid, disgorgement, contractual damages,
diminished profits and future earnings, reputational harm and the curtailment or restructuring of our operations, as well as additional reporting obligations and oversight if we become subject to a
corporate integrity agreement, deferred prosecution agreement or other agreement to resolve allegations of non-compliance with these laws, any of which could adversely affect our ability to operate
our business and our financial results. Defending against any such actions can be costly and time consuming and may require significant financial and personnel resources. Therefore, even if we are
successful in defending against any such actions that may be brought against us, our business may be impaired. Further, if any of the physicians or other healthcare providers or entities with whom we
expect  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.

Third party patient assistance programs that receive financial support from companies have become the subject of enhanced government and regulatory scrutiny. Government enforcement agencies
have shown increased interest in pharmaceutical companies' product and patient assistance programs, including reimbursement support services, and a number of investigations into these programs
have resulted in significant civil and criminal settlements. The United States government has established guidelines that suggest that it is lawful for pharmaceutical manufacturers to make donations
to  charitable  organizations  who  provide  copay  assistance  to  Medicare  patients,  provided  that  such  organizations,  among  other  things,  are  bona  fide  charities,  are  entirely  independent  of  and  not
controlled by the manufacturer, provide aid to applicants on a first-come basis according to consistent financial criteria and do not link aid to use of a donor's product. However, donations to patient
assistance programs have received some negative publicity and have been the subject of multiple government enforcement actions, related to allegations regarding their use to promote branded

45

 
Table of Contents

pharmaceutical products over other less costly alternatives. Specifically, in recent years, there have been multiple settlements resulting out of government claims challenging the legality of patient
assistance programs under a variety of federal and state laws. It is possible that we may make grants to independent charitable foundations that help financially needy patients with their premium,
copay, and co-insurance obligations. If we choose to do so, and if we or our vendors or donation recipients are deemed to fail to comply with relevant laws, regulations or evolving government
guidance in the operation of these programs, we could be subject to damages, fines, penalties, or other criminal, civil, or administrative sanctions or enforcement actions. We cannot ensure that our
compliance controls, policies, and procedures will be sufficient to protect against acts of our employees, business partners, or vendors that may violate the laws or regulations of the jurisdictions in
which we operate. Regardless of whether we have complied with the law, a government investigation could impact our business practices, harm our reputation, divert the attention of management,
increase our expenses, and reduce the availability of foundation support for our patients who need assistance. Further, it is possible that changes in insurer policies regarding copay coupons and/or the
introduction and enactment of new legislation or regulatory action could restrict or otherwise negatively affect these patient support programs, which could result in fewer patients using affected
products, and therefore could have a material adverse effect on our sales, business, and financial condition.

If  we  fail  to  comply  with  our  reporting  and  payment  obligations  under  the  Medicaid  Drug  Rebate  Program  or  other  governmental  pricing  programs,  we  could  be  subject  to  additional
reimbursement requirements, penalties, sanctions and fines, which could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

We  participate  in  the  Medicaid  Drug  Rebate  Program,  the  340B  program,  the  U.S.  Department  of  Veterans  Affairs,  Federal  Supply  Schedule  ("FSS"),  pricing  program,  and  the  Tricare  Retail
Pharmacy program, which require us to disclose average manufacturer pricing, and, in the future may require us to report the average sales price for certain of our drugs to the Medicare program.

Pricing  and  rebate  calculations  vary  across  products  and  programs,  are  complex,  and  are  often  subject  to  interpretation  by  us,  governmental  or  regulatory  agencies  and  the  courts.  Furthermore,
regulatory  and  legislative  changes,  and  judicial  rulings  relating  to  these  programs  and  policies  (including  coverage  expansion),  have  increased  and  will  continue  to  increase  our  costs  and  the
complexity of compliance, have been and will continue to be time-consuming to implement, and could have a material adverse effect on our results of operations, particularly if CMS or another
agency challenges the approach we take in our implementation. For example, in the case of our Medicaid pricing data, if we become aware that our reporting for a prior quarter has changed as a result
of recalculation of the pricing data, we are generally obligated to resubmit the revised data for up to three years after those data originally were due. Such restatements increase our costs and could
result in an overage or underage in our rebate liability for past quarters. Price recalculations also may affect the ceiling price at which we are required to offer our products under the 340B program
and give rise to an obligation to refund entities participating in the 340B program for overcharges during past quarters impacted by a price recalculation.

Civil monetary penalties can be applied if we are found to have knowingly submitted any false price or product information to the government, if we are found to have made a misrepresentation in the
reporting of our government prices, if we fail to submit the required price data on a timely basis, or if we are found to have charged 340B covered entities more than the statutorily mandated ceiling
price.  Additionally,  our  agreement  to  participate  in  the  340B  program  or  our  Medicaid  drug  rebate  agreement  could  be  terminated,  in  which  case  federal  payments  may  not  be  available  under
Medicaid or Medicare Part D for our covered outpatient drugs.

Additionally, if we overcharge the government in connection with our arrangements with FSS or Tricare Retail Pharmacy, we are required to refund the difference to the government. Failure to make
necessary disclosures and/or to identify contract overcharges can result in allegations against us under the FCA and other laws and regulations. Unexpected refunds to the government, and responding
to a government investigation or enforcement action, would be expensive and time-consuming, and could have a material adverse effect on our business, financial condition, results of operations and
growth prospects.

Further, legislation may be introduced that, if passed, would, among other things, further expand the 340B program to additional covered entities or would require participating manufacturers to agree
to provide 340B discounted pricing on drugs used in an inpatient setting, and any additional future changes to the definition of average manufacturer price or the Medicaid unit rebate amount could
affect our 340B ceiling price calculations and negatively impact our results of operations. Additionally, certain pharmaceutical manufacturers are involved in ongoing litigation regarding contract
pharmacy arrangements under the 340B program. The outcome of those judicial proceedings and the potential impact on the way in which manufacturers extend discounts to covered entities through
contract pharmacies remain uncertain.

Laws and regulations governing any international operations we may have in the future may preclude us from developing, manufacturing and selling certain product candidates outside the
United States and require us to develop and implement costly compliance programs.

We currently have operations in the United States and in Ireland, and we maintain relationships with CMOs in certain parts of Europe, Asia and the United States for the manufacture of our products
and product candidates. The Foreign Corrupt Practices Act ("FCPA") prohibits any United States individual or business from paying, offering, authorizing payment or offering of anything of value,
directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining
or retaining business. The FCPA also obligates companies whose securities are listed in the United States to comply with certain accounting provisions requiring the company to maintain books and
records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for
international operations. The anti-bribery provisions of the FCPA are enforced

46

Table of Contents

primarily by the DOJ. The Securities and Exchange Commission ("SEC") is involved with enforcement of the books and records provisions of the FCPA and may suspend or bar issuers from having
its securities traded on United States exchanges for violations of the FCPA’s accounting provisions.

Various laws, regulations and executive orders also restrict the use and dissemination outside the United States, or the sharing with certain non-United States nationals, of information classified for
national  security  purposes,  as  well  as  certain  products  and  technical  data  relating  to  those  products.  As  we  expand  our  presence  outside  the  United  States,  we  are  required  to  dedicate  additional
resources to comply with laws and regulations in each new jurisdiction in which we are operating or plan to operate, and these laws may preclude us from developing, manufacturing, or selling
certain drugs and product candidates in these jurisdictions, which could limit our growth potential and increase our development costs.

The creation and implementation of international business practices compliance programs, particularly FCPA compliance, are costly and such programs are difficult to enforce, especially in countries
in which corruption is a recognized problem and where reliance on third parties is required. In addition, the FCPA presents particular challenges in the pharmaceutical industry because, 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 FCPA enforcement actions. Indictment alone under the FCPA can lead to suspension of the right to do
business with the United States government until the pending claims are resolved. Conviction of a violation of the FCPA can result in long-term disqualification as a government contractor.

Accordingly, our failure to comply with the FCPA or other export control, anti-corruption, anti-money laundering and anti-terrorism laws or regulations and other similar laws governing international
business practices may result in substantial penalties, including suspension or debarment from government contracting. The termination of a government contract or relationship as a result of our
failure to satisfy any of our obligations under such laws would have a negative impact on our operations and harm our reputation and ability to procure government contracts. We cannot assure you
that our compliance policies and procedures are or will be sufficient or that our directors, officers, employees, representatives, consultants and agents have not engaged and will not engage in conduct
for which we may be held responsible, nor can we assure you that our business partners have not engaged and will not engage in conduct that could materially affect their ability to perform their
contractual obligations to us or even result in our being held liable for such conduct.

Governments outside the United States tend to impose strict price controls, which may adversely affect our revenues, if any.

In some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For
example, the EU 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.  In  these  countries,  pricing  negotiations  with  governmental  authorities  can  take  considerable  time  after  the  receipt  of  marketing  approval  for  a  product.  In
addition,  there  can  be  considerable  pressure  by  governments  and  other  stakeholders  on  prices  and  reimbursement  levels,  including  as  part  of  cost  containment  measures.  Political,  economic  and
regulatory developments may further complicate pricing negotiations, and pricing negotiations may continue after coverage and reimbursement have been obtained. Reference pricing used by various
countries and parallel distribution or arbitrage between low-priced and high-priced countries can further reduce prices. To obtain reimbursement or pricing approval in some countries, we, or any
future collaborators, may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidates to other available therapies, which is time consuming and costly. A
Member State may approve a specific price for the medicinal product 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  pharmaceutical  products  will  allow  favorable  reimbursement  and  pricing
arrangements for any of our product candidates. Historically, products launched in the EU do not follow price structures of the United States and generally prices tend to be significantly lower. If
reimbursement of our product candidates is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed.

Risks Related to Industry Competition

If the FDA or other applicable regulatory authorities approve generic products that compete with any of our products or product candidates, the sales of our products and product candidates, if
approved, could be adversely affected.

Once  an  NDA,  including  a  Section  505(b)(2)  application,  is  approved,  the  product  covered  becomes  a  "listed  drug"  which  can  be  cited  by  potential  competitors  in  support  of  approval  of  an
abbreviated new drug application ("ANDA"). FDA regulations and other applicable regulations and policies provide incentives to manufacturers to create modified versions of a drug to facilitate the
approval  of  an  ANDA  or  other  application  for  similar  substitutes.  If  these  manufacturers  demonstrate  that  their  product  has  the  same  active  ingredient(s),  dosage  form,  strength,  route  of
administration, and conditions of use, or labeling, as our products or product candidates, they might only be required to conduct a relatively inexpensive study to show that their generic product is
absorbed in the body at the same rate and to the same extent as, or is bioequivalent to, our products or product candidates. In some cases, even this limited bioequivalence testing can be waived by the
FDA. Laws have also been enacted to facilitate the development of generic drugs and biologics based off recently approved NDAs and BLAs. The Creating and Restoring Equal Access to Equivalent
Samples Act ("CREATES Act") was enacted in 2019 requiring sponsors of approved NDAs and BLAs to provide sufficient quantities of product

47

Table of Contents

samples on commercially reasonable, market-based terms to eligible product developers. The law establishes a private right of action allowing developers to sue application holders that refuse to sell
them product samples needed to support their applications. Providing product samples and allocating additional resources to respond to such requests or any legal challenges under this law, could
adversely impact our business. Competition from generic equivalents to our products or product candidates could substantially limit our ability to generate revenues and therefore to obtain a return on
the investments we have made in our products or product candidates. For example, Amphastar's ANDA for generic Glucagon for Injection Emergency Kit was approved by the FDA on December 29,
2020 for the treatment of severe hypoglycemia and while we previously relied on orphan drug exclusivity in the marketing and sale of Keveyis through the expiration of orphan drug exclusivity,
Torrent Pharmaceuticals Limited’s ANDA for generic dichlorphenamide was approved on December 29, 2022. We intend to rely on orphan drug exclusivity and if available, NCE exclusivity in the
marketing and sale of Recorlev. While we applied for NCE exclusivity for Recorlev under section 505(u) of the FDCA, the FDA may determine that the Recorlev application does not meet the
eligibility criteria under 505(u) for NCE exclusivity.

Risks Related to Product Development

Our failure to successfully identify, develop and market additional product candidates, or acquire additional product candidates or enter into collaborations or other commercial agreements
could impair our ability to grow.

As  part  of  our  growth  strategy,  we  intend  to  identify,  develop  and  market  additional  product  candidates  leveraging  our  formulation  science,  and  evaluate  other  commercial  relationships  through
collaborations or other strategic agreements. We are exploring various therapeutic opportunities for our pipeline programs. We may spend several years completing our development of any particular
current or future internal product candidates, and failure can occur at any stage. The product candidates to which we allocate our resources may not end up being successful. Gvoke, which delivers
ready-to-use glucagon via a pre-filled syringe or auto-injector, was approved by the FDA in 2019 for the treatment of severe hypoglycemia in pediatric (aged two years and above) and adult patients
with diabetes. While we have identified several additional potential applications of our ready-to-use glucagon, there is no guarantee that we will be able to utilize our formulation science to obtain
approval of additional product candidates.

In  the  future,  we  may  be  dependent  upon  other  pharmaceutical  companies,  academic  scientists  and  other  researchers  to  sell  or  license  product  candidates,  approved  products  or  the  underlying
technology to us. The process of proposing, negotiating and implementing a license or acquisition of a product candidate or approved product is lengthy and complex. Other companies, including
some with substantially greater financial, marketing and sales resources, may compete with us for the license or acquisition of product candidates and approved products. In addition, we expect to
seek one or more collaborators for the development and commercialization of one or more of our products or product candidates, particularly with respect to our pipeline product candidates or foreign
geographies. We face significant competition in seeking appropriate collaborators. We have limited resources to identify and execute the acquisition or in-licensing of third-party products, businesses
and technologies or enter into collaborations or other strategic arrangements and integrate them into our current infrastructure. Moreover, we may devote resources to potential acquisitions or in-
licensing  opportunities  that  are  never  completed,  or  we  may  fail  to  realize  the  anticipated  benefits  of  such  efforts.  We  may  not  be  able  to  acquire  the  rights  to  additional  product  candidates  or
approved products on terms that we find acceptable, or at all.

In addition, future acquisitions may entail numerous operational and financial risks, including: 

  

  exposure to unknown liabilities;

disruption of our business and diversion of our management’s time and attention to develop acquired products or technologies;
incurrence of substantial debt, dilutive issuances of securities or depletion of cash to pay for acquisitions;
higher than expected acquisition and integration costs;
difficulty in combining the operations and personnel of any acquired businesses with our operations and personnel;
increased amortization expenses;
impairment of relationships with key suppliers or customers of any acquired businesses due to changes in management and ownership; and
inability to motivate or retain key employees of any acquired businesses.

Further, any product candidate that we identify internally or acquire would require additional development efforts prior to commercial sale, including extensive clinical testing and approval by the
FDA and other regulatory authorities.

Risks Related to Our Intellectual Property

Risks Related to Protecting Our Intellectual Property

Our success depends on our ability to protect our intellectual property and proprietary formulation science, as well as the ability of our collaborators to protect their intellectual property and
proprietary formulation science.

Our success depends in large part on our ability to obtain and maintain patent protection and trade secret protection in the United States and other countries with respect to the use, formulation and
structure of our proprietary product candidates, the methods used to manufacture them, the related therapeutic targets and associated methods of treatment as well as on successfully defending these
patents against potential third-party challenges. Our ability to protect our products and product candidates from unauthorized making, using, selling, offering to sell or importing by third parties is
dependent on the extent to which we have rights under valid and enforceable patents that cover these activities. If we do not adequately protect our intellectual property rights, competitors may be
able to erode or negate any competitive advantage we may have, which could harm our business and ability to achieve profitability. To protect our proprietary position, we file patent applications in
the United States and abroad related to our novel product candidates that are important to our business; we may in the future also license or purchase patents or applications owned by others. The
patent application and approval process is expensive and time consuming. We may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely
manner. Moreover, obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental
patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

If the scope of the patent protection we or our potential licensors obtain is not sufficiently broad, we may not be able to prevent others from developing and commercializing technology and products
similar or identical to ours. The degree of patent protection we require to successfully compete in the marketplace may be unavailable or severely limited in some cases and may not adequately
protect our rights or permit us to gain or keep any competitive advantage. We cannot provide any assurances that any of our patents have, or that any of our pending patent applications that mature
into issued patents will include, claims with a scope sufficient to protect our current and future product candidates or otherwise provide any competitive advantage. In addition, to the extent that we
license intellectual property in the future, we cannot assure you that those licenses will remain in force. In addition, the laws of foreign countries may not protect our rights to the same extent as the
laws of the United States. Furthermore, patents have a limited lifespan. In the United States, the natural expiration of a patent is generally twenty years after it is filed. Various extensions may be
available; however, the life of a patent and the protection it affords are limited. 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.

Even if they are unchallenged, our patents and pending patent applications, if issued, may not provide us with any meaningful protection or prevent competitors from designing around our patent
claims to circumvent our patents by developing similar or alternative technologies or therapeutics in a non-infringing manner. For example, a third party may develop a competitive therapy that
provides benefits similar to one or more of our products or product candidates but that uses a formulation and/or a device that falls outside the scope of our patent protection. If the patent protection
provided by the patents and patent applications we hold or pursue with respect to our products or product candidates is not sufficiently broad to exclude such competition, our ability to successfully
commercialize our products or product candidates could be negatively affected, which would harm our business. Although we currently own all of our patents and our patent applications, similar
risks would apply to any patents or patent applications that we may in-license in the future.

We, or any future partners, collaborators, or licensees, may fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to
obtain patent protection on them. Therefore, we may miss potential opportunities to strengthen our patent position.

It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example with respect to proper priority claims, inventorship,
claim scope, or requests for patent term adjustments. If we or our partners, collaborators, licensees or licensors fail to establish, maintain or protect such patents and other intellectual property rights,
such rights may be reduced or eliminated. If our partners, collaborators, licensees or licensors are not fully cooperative or disagree with us as to the prosecution, maintenance or enforcement of any
patent rights, such patent rights could be compromised. If there are material defects in the form, preparation, prosecution, or enforcement of our patents or patent applications, such patents may be
invalid and/or unenforceable, and such applications may never result in valid, enforceable patents. Any of these outcomes could impair our ability to prevent competition from third parties, which
may have an adverse impact on our business.

The patent position of biotechnology and pharmaceutical companies generally is highly uncertain. No consistent policy regarding the breadth of claims allowed in biotechnology and pharmaceutical
patents  has  emerged  to  date  in  the  United  States  or  in  many  foreign  jurisdictions.  In  addition,  the  determination  of  patent  rights  with  respect  to  pharmaceutical  compounds  commonly  involves
complex legal and factual questions, which has in recent years been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of our patent rights
are highly uncertain.

Moreover, because the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability, our patents or pending patent applications may be challenged in the courts or
patent offices in the United States and abroad. There is no assurance that all of the potentially relevant prior art relating to our patents and patent applications has been found. If such prior art exists, it
may be used to invalidate a patent or may prevent a patent from issuing from a pending patent application. For example, such patent filings may be subject to a third-party pre-issuance submission of
prior art to the USPTO and/or to other patent offices around the world.

49

Table of Contents

Alternately or additionally, we may become involved in post-grant review procedures, oppositions, derivations proceedings, reexaminations, inter partes review or interference proceedings, in the
United States or elsewhere, challenging patents or patent applications in which we have rights, including patents on which we rely to protect our business. An adverse determination in any such
challenges may result in loss of exclusivity or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to exclude others from using or
commercializing similar or identical technology and products, or may limit the duration of the patent protection of our technology and products.

Pending and future patent applications may not result in patents being issued which protect our business, in whole or in part, or which effectively prevent others from commercializing competitive
products.  Changes  in  either  the  patent  laws  or  interpretation  of  the  patent  laws  in  the  United  States  and  other  countries  may  diminish  the  value  of  our  patents  or  narrow  the  scope  of  our  patent
protection.  In  addition,  the  laws  of  foreign  countries  may  not  protect  our  rights  to  the  same  extent  or  in  the  same  manner  as  the  laws  of  the  United  States.  For  example,  patent  laws  in  various
jurisdictions, including significant commercial markets such as Europe, restrict the patentability of methods of treatment of the human body more than United States law does.

The patent application process is subject to numerous risks and uncertainties, and there can be no assurance that we or any future development partners will be successful in protecting our product
candidates by obtaining, maintaining and defending patents. These risks and uncertainties include the following:









the  USPTO  and  various  foreign  governmental  patent  agencies  require  compliance  with  a  number  of  procedural,  documentary,  fee  payment  and  other  provisions  during  the  patent
process. There are situations in which noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of patent rights in the
relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would otherwise have been the case;
patent applications may not result in any patents being issued;
patents that may be issued may be challenged, invalidated, modified, revoked, circumvented, found to be unenforceable or otherwise may not provide any competitive advantage;
our competitors, many of whom have substantially greater resources and many of whom have made significant investments in competing technologies, may seek or may have already
obtained patents that will limit, interfere with or eliminate our ability to make, use, and sell our potential product candidates;
there may be significant pressure on the United States government and international governmental bodies to limit the scope of patent protection both inside and outside the United States
for disease treatments that prove successful, as a matter of public policy regarding worldwide health concerns; and
countries other than the United States may have patent laws less favorable to patentees than those upheld by United States courts, allowing foreign competitors a better opportunity to
create, develop and market competing product candidates in such countries.

Issued patents that we have or may in the future obtain or license may not provide us with any meaningful protection, prevent competitors from competing with us or otherwise provide us with any
competitive advantage. Our competitors may be able to circumvent our or our future licensors’ patents by developing similar or alternative technologies or products in a non-infringing manner. Our
competitors may also seek approval to market their own products similar to or otherwise competitive with our products. Alternatively, our competitors may seek to market generic versions of any
approved products by submitting ANDAs to the FDA in which they claim that patents owned or in the future licensed by us are invalid, unenforceable or not infringed. In these circumstances, we
may need to defend or assert our patents, or both, including by filing lawsuits alleging patent infringement. In any of these types of proceedings, a court or other agency with jurisdiction may find our
patents invalid or unenforceable, or that our competitors are competing in a non-infringing manner. Thus, even if we have valid and enforceable patents, these patents still may not provide protection
against competing products or processes sufficient to achieve our business objectives.

We have entered into a license agreement with a third party (and may, in the future, enter into additional such license agreements with other third parties) pursuant to which they have the right, but not
the  obligation,  in  certain  circumstances  to  control  enforcement  of  our  licensed  patents  or  defense  of  any  claims  asserting  the  invalidity  of  these  patents.  Even  if  we  are  permitted  to  pursue  such
enforcement or defense, we will require the cooperation of those licensees and cannot guarantee that we would receive it and on what terms. We cannot be certain that those licensees will allocate
sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. If we cannot obtain patent protection or enforce
existing or future patents against third parties, our competitive position and our financial condition could suffer.

In  addition,  we  rely  on  the  protection  of  our  trade  secrets  and  proprietary  know-how.  Although  we  take  steps  to  protect  our  trade  secrets  and  unpatented  know-how,  including  entering  into
confidentiality  agreements  with  third  parties  and  confidential  information  and  inventions  agreements  with  employees,  consultants  and  advisors,  we  cannot  provide  any  assurances  that  all  such
agreements have been duly executed, and third parties may still obtain this information or may come upon this or similar information independently. Additionally, if the steps taken to maintain our
trade secrets are deemed inadequate, we may have insufficient recourse against third parties for misappropriating our trade secrets. If any of these events occurs or if we otherwise lose protection for
our trade secrets or proprietary know-how, our business may be harmed.

50

Table of Contents

Our  reliance  on  third  parties  requires  us  to  share  our  trade  secrets,  which  increases  the  possibility  that  a  competitor  will  discover  them  or  that  our  trade  secrets  will  be  misappropriated  or
disclosed.

Because we rely on third parties to develop and manufacture our product candidates, we must, at times, share trade secrets with them. We seek to protect our proprietary technology in part by entering
into confidentiality agreements and, if applicable, material transfer agreements, collaborative research agreements, consulting agreements or other similar agreements with our collaborators, advisors,
employees,  and  consultants  prior  to  beginning  research  or  disclosing  proprietary  information.  These  agreements  typically  limit  the  rights  of  the  third  parties  to  use  or  disclose  our  confidential
information, such as trade secrets. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases the risk
that  such  trade  secrets  become  known  by  our  competitors,  are  inadvertently  incorporated  into  the  technology  of  others,  or  are  disclosed  or  used  in  violation  of  these  agreements.  Given  that  our
proprietary position is based, in part, on our know-how and trade secrets, a competitor's discovery of our trade secrets or other unauthorized use or disclosure would impair our competitive position
and may harm our business.

The patent positions of pharmaceutical, biotechnology and other life sciences companies can be highly uncertain and involve complex legal and factual questions for which important legal principles
remain unresolved. Changes in either the patent laws or in interpretations of patent laws in the United States and other countries may diminish the value of our intellectual property. Further, the
determination that a patent application or patent claim meets all of the requirements for patentability is a subjective determination based on the application of law and jurisprudence. The ultimate
determination  by  the  USPTO  or  by  a  court  or  other  trier  of  fact  in  the  United  States,  or  corresponding  foreign  national  patent  offices  or  courts,  on  whether  a  claim  meets  all  requirements  of
patentability cannot be assured. We have not conducted searches for third-party publications, patents and other information that may affect the patentability of claims in our various patent applications
and patents, so we cannot be certain that all relevant information has been identified. Accordingly, we cannot predict the breadth of claims that may be allowed or enforced in our patent applications
and patents, in any future licensed patents or patent applications or in third-party patents.

We cannot provide assurances that any claim(s) in any of our patent applications will be found to be patentable, including over our own prior art patents, or that any such patent applications will issue
as patents. Neither can we make assurances as to the scope of any claims that may issue from our pending and future patent applications nor to the outcome of any proceedings instituted by any
potential  third  parties  that  could  challenge  the  patentability,  validity  or  enforceability  of  our  patents  and  patent  applications  in  the  United  States  or  foreign  jurisdictions.  Any  such  challenge,  if
successful, could limit patent protection for our products and product candidates and/or materially harm our business.

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our
competitive advantage. For example:









we may not be able to generate sufficient data to support full patent applications that protect the entire breadth of developments in one or more of our programs;
it is possible that one or more of our pending patent applications will not become an issued patent or, if issued, that the patent(s) will not: (a) be sufficient to protect our technology,
(b) provide us with a basis for commercially viable products and/or (c) provide us with any competitive advantages;
if our pending applications issue as patents, they may be challenged by third parties as not infringed, invalid or unenforceable under the United States or foreign laws; or
if issued, the patents under which we hold rights may not be valid or enforceable.

In addition, to the extent that we are unable to obtain and maintain patent protection for one of our products or product candidates or in the event that such patent protection expires, it may no longer
be cost-effective to extend our portfolio by pursuing additional development of a product or product candidate for follow-on indications.

We also may rely on trade secrets to protect our technologies or products, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to
protect. Our employees, consultants, contractors, outside scientific collaborators, and other advisers may unintentionally or willfully disclose our information to competitors. Enforcing a claim that a
third-party  entity  illegally  obtained  and  is  using  any  of  our  trade  secrets  is  expensive  and  time  consuming,  and  the  outcome  is  unpredictable.  In  addition,  courts  outside  the  United  States  are
sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop equivalent knowledge, methods, and know-how.

Patent terms may be inadequate to protect our competitive position on our products for an adequate amount of time.

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. Where available, we will seek extensions of patent terms in the United States and, if available, in other countries where we are prosecuting patents. In the United
States, the Drug Price Competition and Patent Term Restoration Act of 1984 permits a patent term extension of up to five years beyond the normal expiration of the patent, which is limited to the
approved indication (or any additional indications approved during the period of extension). However, the applicable authorities, including the FDA and the USPTO in the United States and any
equivalent regulatory authority in other countries, may not agree with our assessment of whether such extensions are available and may refuse to grant extensions to our patents or may grant more
limited extensions than we request. If this occurs, our competitors may be able to take

51

Table of Contents

advantage of our investment in development and clinical trials by referencing our clinical and preclinical data and launch their product earlier than might otherwise be the case.

Our unpatented trade secrets, know-how, confidential and proprietary information, and technology may be inadequately protected.

We rely in part on unpatented trade secrets, know-how and technology. This intellectual property is difficult to protect, especially in the pharmaceutical industry, where much of the information about
a product must be submitted to regulatory authorities during the regulatory approval process. We seek to protect trade secrets, confidential information and proprietary information, in part, by entering
into confidentiality and invention assignment agreements with employees, consultants, and others. These parties may breach or terminate these agreements, and we may not have adequate remedies
for such breaches. Furthermore, these agreements may not provide meaningful protection for our trade secrets or other confidential or proprietary information or result in the effective assignment to
us of intellectual property and may not provide an adequate remedy in the event of unauthorized use or disclosure of confidential information or other breaches of the agreements. Despite our efforts
to  protect  our  trade  secrets  and  our  other  confidential  and  proprietary  information,  we  or  our  collaboration  partners,  board  members,  employees,  consultants,  contractors,  or  scientific  and  other
advisors may unintentionally or willfully disclose our proprietary information to competitors.

Thus, there is a risk that our trade secrets and other confidential and proprietary information could have been, or could, in the future, be shared by any of our former employees with, and be used to
the benefit of, any company that competes with us.

If we fail to maintain trade secret protection or fail to protect the confidentiality of our other confidential and proprietary information, our competitive position may be adversely affected. Competitors
may  also  independently  discover  our  trade  secrets.  Enforcement  of  claims  that  a  third  party  has  illegally  obtained  and  is  using  trade  secrets  is  expensive,  time  consuming  and  uncertain.  If  our
competitors independently develop equivalent knowledge, methods and know-how, we would not be able to assert our trade secret protections against them, which could have a material adverse
effect on our business.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

Our  trademarks  or  trade  names  may  be  challenged,  infringed,  circumvented,  or  declared  generic  or  determined  to  be  infringing  on  other  marks.  We  rely  on  both  registration  and  common  law
protection for our trademarks. We may not be able to protect our rights to these trademarks and trade names or may be forced to stop using these names, which we need for name recognition by
potential partners or customers in our markets of interest. During the trademark registration process, we may receive Office Actions from the USPTO objecting to the registration of our trademark.
Although we would be given an opportunity to respond to those objections, we may be unable to overcome such objections. In addition, in the USPTO and in comparable agencies in many foreign
jurisdictions, third parties are given an opportunity to oppose pending trademark applications and/or to seek the cancellation of registered trademarks. Opposition or cancellation proceedings may be
filed against our trademarks, and our trademarks may not survive such proceedings. If we are unable to establish name recognition based on our trademarks and trade names, we may not be able to
compete effectively and our business may be adversely affected.

Risks Related to Intellectual Property Litigation

The pharmaceutical industry is characterized by frequent patent litigation, and we could become subject to litigation that could be costly, result in the diversion of management’s time and efforts,
require us to pay damages or prevent us from marketing our existing or future products.

Our commercial success depends in part on our ability to develop, manufacture, market and sell our products that have been approved for sale, and to use our proprietary technology without alleged
or actual infringement, misappropriation or other violation of the patents and proprietary rights of third parties. There have been many lawsuits and other proceedings involving patent and other
intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, oppositions and reexamination proceedings before the USPTO,
and corresponding foreign patent offices. Numerous United States and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we will
market products and are developing product candidates. Some claimants, who may include our competitors in both the United States and abroad, may have substantially greater resources than we do
and may be able to sustain the costs of complex intellectual property litigation to a greater degree and for longer periods of time than we could. In addition, patent holding companies that focus solely
on extracting royalties and settlements by enforcing patent rights may target us. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our
products and product candidates may be subject to claims of infringement of the intellectual property rights of third parties.

We cannot be sure that we know of each and every patent and pending application in the United States and abroad that is relevant or necessary to the commercialization of Gvoke, Recorlev, Keveyis,
or our product candidates. Generally, we do not conduct independent reviews of patents issued to third parties. The large number of patents, the rapid rate of new patent issuances, the complexities of
the technology involved, and uncertainty of litigation increase the risk of business assets and management’s attention being diverted to patent litigation. Because patent applications can take up to 18
months after filing to become public, and many years to issue, there may be currently pending patent applications that may later result in issued patents upon which our products or product candidates
may infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. If any third-party patents were held by a court of competent
jurisdiction to cover the manufacturing process of any of our products or product candidates, any compositions formed during the manufacturing process or any final product itself, the

52

Table of Contents

holders of any such patents may be able to block our ability to commercialize such product or product candidate unless we obtained a license under the applicable patents, or until such patents expire
or are finally determined to be invalid or unenforceable. Similarly, if any third-party patents were held by a court of competent jurisdiction to cover aspects of our compositions, formulations, or
methods of treatment, prevention or use, the holders of any such patents may be able to block our ability to develop and commercialize the applicable product or product candidate unless we obtained
a license or until such patent expires or is finally determined to be invalid or unenforceable. In either case, such a license may not be available on commercially reasonable terms, or at all. Even if we
were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us.

We  may  become  involved  in  lawsuits  to  protect  or  enforce  our  patents  or  other  intellectual  property,  which  could  be  expensive,  time  consuming  and  unsuccessful.  Competitors  may  infringe  our
patents,  trademarks,  copyrights  or  other  intellectual  property.  To  counter  infringement  or  unauthorized  use,  we  may  be  required  to  file  infringement  lawsuits,  which  can  be  expensive  and  time
consuming and divert the time and attention of our management and scientific personnel. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against
us alleging that we infringe their patents, in addition to counterclaims asserting that our patents are invalid or unenforceable, or both. In any patent infringement proceeding, there is a risk that a court
will decide that a patent of ours is invalid or unenforceable, in whole or in part, and that we do not have the right to exclude the other party from making, using or selling the invention at issue. There
is also a risk that, even if the validity of such patents is upheld, the court will construe the patent’s claims narrowly or decide that we do not have the right to exclude the other party from making,
using  or  selling  the  invention  at  issue  on  the  grounds  that  our  patent  claims  do  not  cover  the  invention  or  the  other  party's  manufacture,  use  or  sale  of  it.  An  adverse  outcome  in  a  litigation  or
proceeding involving one or more of our patents could limit our ability to assert those patents against those parties or other competitors and may curtail or preclude our ability to exclude third parties
from making and selling similar or competitive products. Similarly, if we assert trademark infringement claims, a court may determine that the marks we have asserted are unenforceable, that the
alleged  infringing  mark  does  not  infringe  our  trademark  rights,  or  that  the  party  against  whom  we  have  asserted  trademark  infringement  has  superior  rights  to  the  marks  in  question.  In  this  last
instance, we could ultimately be forced to cease use of such trademarks.

Others may challenge inventorship or claim an ownership interest in our intellectual property, which could expose it to litigation and have a significant adverse effect on its prospects.

A third party or former employee or collaborator may claim an ownership interest in one or more of our patents or other proprietary or intellectual property rights. A third party could bring legal
actions against us and seek monetary damages and/or enjoin clinical testing, manufacturing, and marketing of the affected product or products. A third party could assert a claim or an interest in any
of such patents or intellectual property. If we become involved in any litigation, it could consume a substantial portion of our resources and cause a significant diversion of effort by our technical and
management personnel.

If any of these actions are successful, in addition to any potential liability for damages, we could be required to obtain a license to continue to manufacture or market the affected product, in which
case  we  may  be  required  to  pay  substantial  royalties  or  grant  cross-licenses  to  our  patents.  We  cannot,  however,  assure  you  that  any  such  license  will  be  available  on  acceptable  terms,  if  at  all.
Furthermore, any potential intellectual property litigation also could force us to do one or more of the following:

  










  stop selling products or using technology that contains the allegedly infringing intellectual property;

lose the opportunity to license our technology to others or to collect royalty payments based upon successful protection and assertion of our intellectual property rights against others;
incur significant legal expenses;
pay substantial damages to the party whose intellectual property rights we may be found to be infringing;
redesign those products that contain the allegedly infringing intellectual property, which could be costly, disruptive and/or infeasible; or
attempt to obtain a license to the relevant intellectual property from third parties, which may not be available on reasonable terms or at all.

The outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in advance, including the demeanor and credibility of witnesses and the identity of any
adverse party. This is especially true in intellectual property cases that may turn on the testimony of experts as to technical facts upon which experts may reasonably disagree. Any litigation or claim
against us, even those without merit, may cause us to incur substantial costs and could place a significant strain on our financial resources, divert the attention of management from our core business,
and harm our reputation.

We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of our competitors or are in breach of non-competition or
non-solicitation agreements with our competitors.

We may also be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of our competitors or are in breach of non-competition or
non-solicitation agreements with our competitors. Many of our employees were previously employed at other pharmaceutical companies, including our competitors or potential competitors, in some
cases until recently. We may be subject to claims that we or our employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of these former employers
or competitors. In addition, we have been and may in the future be subject to claims that we caused an employee to breach the terms of his or her non-competition or non-solicitation agreement.
Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation

53

Table of Contents

could result in substantial costs and could be a distraction to management. If our defense to those claims fails, in addition to paying monetary damages, we may lose valuable intellectual property
rights  or  personnel.  Any  litigation  or  the  threat  thereof  may  adversely  affect  our  ability  to  hire  employees.  A  loss  of  key  personnel  or  their  work  product  could  hamper  or  prevent  our  ability  to
commercialize our products and product candidates, which could have an adverse effect on our business, results of operations and financial condition.

An NDA submitted under Section 505(b)(2) subjects us to the risk that we may be subject to a patent infringement lawsuit that would delay or prevent the review or approval of our product
candidates.

We expect to submit NDAs under Section 505(b)(2) of the FDCA for most of our product candidates. Section 505(b)(2) permits the submission of an NDA where at least some of the information
required for approval comes from preclinical studies and/or clinical trials that were not conducted by, or for, the applicant and for which the applicant has not obtained a right of reference. An NDA
under Section 505(b)(2) would enable us to reference published literature and/or the FDA’s previous findings of safety and effectiveness for a previously approved drug. For NDAs submitted under
Section 505(b)(2), the patent certification and related provisions of the Hatch-Waxman Act apply.

Accordingly, if we rely for approval on the safety or effectiveness information for a previously approved drug, referred to as a listed drug, we will be required to include patent certifications in our
505(b)(2) application regarding any patents covering the listed drug. If there are patents listed in the FDA publication Approved Drug Products with Therapeutic Equivalence Evaluations, commonly
known as the Orange Book, for the listed drug, and we seek to obtain approval prior to the expiration of one or more of those patents, we will be required to submit a Paragraph IV certification
indicating  our  belief  that  the  relevant  patents  are  invalid  or  unenforceable  or  will  not  be  infringed  by  the  manufacture,  use  or  sale  of  the  product  that  is  the  subject  of  our  505(b)(2)  application.
Otherwise, our 505(b)(2) application cannot be approved by the FDA until the expiration of any patents listed in the Orange Book for the listed drug. While we did not submit any Paragraph IV
certifications in connection with our 505(b)(2) NDA for Gvoke, and do not expect to submit any Paragraph IV certifications for our other current product candidates, there can be no assurance that we
will not be required to submit a Paragraph IV certification in respect of any future product candidates for which we seek approval under Section 505(b)(2).

However, an NDA submitted under Section 505(b)(2) subjects us to the risk that we may be subject to a patent infringement lawsuit that would delay or prevent the review or approval of our product
candidates.

If we submit any Paragraph IV certification that may be required, we will be required to provide notice of that certification to the NDA holder and patent owner shortly after our 505(b)(2) application
is accepted for filing. Under the Hatch-Waxman Act, the patent owner may file a patent infringement lawsuit after receiving such notice. If a patent infringement lawsuit is filed within 45 days of the
patent owner’s or NDA holder’s receipt of notice (whichever is later), a one-time, automatic stay of the FDA’s ability to approve the 505(b)(2) NDA is triggered, which typically extends for 30
months  unless  patent  litigation  is  resolved  in  favor  of  the  Paragraph  IV  filer  or  the  patent  expires  before  that  time.  Accordingly,  we  may  invest  a  significant  amount  of  time  and  expense  in  the
development of one or more product candidates only to be subject to significant delay and patent litigation before such product candidates may be commercialized, if at all.

In addition, a 505(b)(2) application will not be approved until any non-patent exclusivity listed in the Orange Book for the listed drug, or for any other drug with the same protected conditions of
approval as our product, has expired. The FDA also may require us to perform one or more additional clinical trials or measurements to support the change from the listed drug, which could be time
consuming and could substantially delay our achievement of regulatory approval. The FDA also may reject any future 505(b)(2) submissions and require us to submit traditional NDAs under Section
505(b)(1), which would require extensive data to establish safety and effectiveness of the product for the proposed use and could cause delay and additional costs. In addition, the FDA could reject
any future 505(b)(2) application and require us to submit an ANDA if, before the submission of our 505(b)(2) application, the FDA approves an application for a product that is pharmaceutically
equivalent to ours. These factors, among others, may limit our ability to commercialize our product candidates successfully.

We may not be able to enforce our intellectual property rights throughout the world.

We may not be able to enforce our intellectual property rights throughout the world. Filing, prosecuting, enforcing and defending patents on our products and product candidates in all countries
throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. The
requirements for patentability may differ in certain countries, particularly in developing countries; thus, even in countries where we do pursue patent protection, there can be no assurance that any
patents will issue with claims that cover our products and product candidates.

Moreover,  our  ability  to  protect  and  enforce  our  intellectual  property  rights  may  be  adversely  affected  by  unforeseen  changes  in  foreign  intellectual  property  laws.  Additionally,  laws  of  some
countries  outside  the  United  States  and  Europe  do  not  afford  intellectual  property  protection  to  the  same  extent  as  the  laws  of  the  United  States  and  Europe.  Many  companies  have  encountered
significant  problems  in  protecting  and  defending  intellectual  property  rights  in  certain  foreign  jurisdictions.  The  legal  systems  of  some  countries,  including  India,  China  and  other  developing
countries, do not favor the enforcement of patents and other intellectual property rights. This could make it difficult for us to stop the infringement of our patents or the misappropriation of our other
intellectual property rights. For example, many foreign countries have compulsory licensing laws under which a patent owner must grant licenses to third parties. Consequently, we may not be able to
prevent third parties from practicing our inventions in certain countries outside the

54

Table of Contents

United States and Europe. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop and market their own products and, further, may export
otherwise infringing products to territories where we have patent protection, if our ability to enforce our patents to stop infringing activities is inadequate. These products may compete with our
products, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Agreements through which we may license patent rights may not give us sufficient rights to permit us to pursue enforcement of those licensed patents or defense of any claims asserting the invalidity
of these patents or the ability to control enforcement or defense of such patent rights in all relevant jurisdictions as requirements may vary.

Proceedings to enforce our patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and resources from other aspects of our business.
Moreover, such proceedings could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims
against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be commercially meaningful. Furthermore, while we intend to protect our
intellectual property rights in major markets for our products, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market our
products. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate.

Even if we establish infringement, the court may decide not to grant an injunction against further infringing activity and instead award only monetary damages, which may or may not be an adequate
remedy. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be
compromised by disclosure during litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or
investors perceive these results to be negative, it could adversely affect the price of shares of our common stock. Moreover, there can be no assurance that we will have sufficient financial or other
resources to file and pursue such infringement claims, which typically last for years before they are concluded. Even if we ultimately prevail in such claims, the monetary cost of such litigation and
the diversion of the attention of our management and scientific personnel could outweigh any benefit we receive as a result of the proceedings.

Risk Related to Intellectual Property Laws

Changes to the patent law in the United States and other jurisdictions could diminish the value of our patents in general, thereby impairing our ability to protect our products.

As  is  the  case  with  other  biopharmaceutical  companies,  our  success  is  heavily  dependent  on  intellectual  property,  particularly  patents.  Obtaining  and  enforcing  patents  in  the  biopharmaceutical
industry involve both technological and legal complexity and are therefore costly, time consuming and inherently uncertain. Changes in patent statutes, regulations promulgated under them, and court
holdings interpreting the statutes and regulations could make it more difficult to obtain patent protection for our inventions and increase the uncertainties and costs surrounding the prosecution of our
patent applications and the enforcement or defense of our issued patents, all of which could harm our business, results of operations and financial condition. Depending on future actions by the United
States Congress, the United States courts, the USPTO and the relevant law-making bodies in other countries, the laws and regulations governing patents could change in unpredictable ways that could
weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

Further,  for  a  patent  with  an  effective  filing  date  of  March  16,  2013  or  later,  a  petition  for  post-grant  review  can  be  filed  by  a  third  party  in  a  nine-month  window  from  issuance  of  the  patent.
Alternatively, a petition for inter partes review can be filed after the nine-month period for filing a post-grant review petition has expired. Post-grant review proceedings can be brought on any ground
of invalidity, whereas inter partes review proceedings can only raise an invalidity challenge based on published prior art and patents. In these adversarial actions, the USPTO reviews patent claims
without the presumption of validity afforded to the United States patents in lawsuits in the United States federal courts and uses a lower burden of proof than used in litigation in the United States
federal courts. Therefore, it is generally considered easier and less costly for a competitor or third party to have a United States patent invalidated in a USPTO post-grant review or inter partes review
proceeding than in a litigation in a United States federal court. If any of our patents are challenged by a third party in such a USPTO proceeding, there is no guarantee that we will be successful in
defending the patent, which could result in a loss of the challenged patent right to us.

Risks Related to Employee Matters, Managing Growth and Ongoing Operations

Risks Related to Potentially Under-resourced Regulatory Authorities

Disruptions at the FDA, the SEC and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire and retain key leadership and other
personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on
which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA or other similar regulatory agencies to review and approve new products can be affected by a variety of factors, including government budget and funding levels, global health
concerns, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. In addition, government funding of the SEC and other government
agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

For example, over the last several years the United States government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA,
SEC  and  other  government  employees  and  stop  critical  activities.  If  a  prolonged  government  shutdown  occurs,  or  if  global  health  concerns  prevent  the  FDA  or  other  regulatory  authorities  from
conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could
have  a  material  adverse  effect  on  our  business.  Further,  in  our  operations  as  a  public  company,  future  government  shutdowns  could  impact  our  ability  to  access  the  public  markets  and  obtain
necessary capital in order to properly capitalize and continue our operations.

Risk Related to Employment Matters

Our business could suffer if we lose the services of key members of our senior management or if we are not able to attract and retain other key employees and consultants.

We are dependent upon the continued services of key members of our executive management and a limited number of key advisors and personnel. In particular, we are highly dependent on the skills
and leadership of our executive management team, including Paul Edick, our Chief Executive Officer, Steven Pieper, our Chief Financial Officer, John Shannon, our President and Chief Operating
Officer, Ken Johnson, our Senior Vice President, Global Development and Medical Affairs, and Beth Hecht, our Chief Legal Officer and Corporate Secretary. The loss of any one of these individuals
could  disrupt  our  operations  or  our  strategic  plans.  Our  industry  has  experienced  a  high  rate  of  turnover  of  management  personnel  in  recent  years.  Any  of  our  personnel  may  terminate  their
employment at will. If we lose one or more of our executive officers or other key employees, our ability to implement our business strategy successfully could be seriously harmed. Furthermore,
replacing executive officers or other key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills
and experience required to develop, gain marketing approval of and commercialize products successfully.

Additionally, our future success will depend on, among other things, our ability to continue to hire and retain the necessary qualified scientific, technical, and managerial personnel, for whom we
compete with numerous other companies, academic institutions, and organizations. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these
additional key employees on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the
hiring of scientific and clinical personnel from universities and research institutions.

We rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors
may be employed by other entities and may have commitments under consulting or advisory contracts with those entities that may limit their availability to us. If we are unable to continue to attract
and retain highly qualified personnel, our ability to commercialize our products and to develop and commercialize our product candidates will be limited.

Risks Related to Our Common Stock

Risks Related to Investment in Securities

Our stock price has been and will likely continue to be volatile, and you may lose part or all of your investment.

The trading price of our common stock historically has been highly volatile and could continue to be subject to large fluctuations in response to the risk factors discussed in this section, and others
beyond our control, including:

   our ability to successfully commercialize Gvoke, Recorlev, and Keveyis;
   regulatory actions with respect to our products and product candidates;


regulatory actions with respect to our competitors’ products and product candidates;
the success of existing or new competitive products or technologies;
results of clinical trials of product candidates of our competitors;
announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures, collaborations or capital commitments;
the timing and results of clinical trials of our pipeline product candidates;
commencement or termination of collaborations for our development programs;
the results of our efforts to develop additional product candidates or products;
the level of expenses related to any of our product candidates or clinical development programs;
failure or discontinuation of any of our development programs;
the pricing and reimbursement of Gvoke, Recorlev, Keveyis or any of our product candidates that may be approved;
regulatory or legal developments in the United States and other countries;
developments or disputes concerning patent applications, issued patents or other proprietary rights;
the recruitment or departure of key personnel;
actual or anticipated changes in estimates as to financial results or development timelines;
announcement or expectation of additional financing efforts;
sales of our common stock by our insiders or other stockholders;
variations in our financial results or those of companies that are perceived to be similar to us;
changes in estimates or recommendations by securities analysts, if any, that cover our stock;
changes in the structure of healthcare payment systems;
market conditions in the pharmaceutical and biotechnology sectors;
general economic, industry and market conditions, including impacts from inflation, interest rate increases, major bank failure or sustained financial market illiquidity; and
any public health crisis, such as a resurgence of the COVID-19 pandemic.

In recent years, the stock markets, and particularly the stock of smaller pharmaceutical and biotechnology companies, at times have experienced price and volume fluctuations that have often been
unrelated or disproportionate to the operating performance of affected companies. Broad market and industry factors may significantly affect the market price of our common stock unrelated to our
actual operating performance. Since shares of our common stock were sold in our IPO in June 2018 at a price of $15.00 per share, our stock price has fluctuated significantly.

In addition, in the past, class action litigation has often been instituted against companies whose securities have experienced periods of volatility in market price. Securities litigation brought against
us in connection with volatility in our stock price, regardless of the merit or ultimate results of such litigation, could result in substantial costs, which would hurt our financial condition and operating
results and divert management’s attention and resources from our business. On March 4, 2024, the closing price of a share of our common stock was $3.04 per share.

The conversion of any of the Convertible Notes or other convertible securities into shares of common stock could have a material dilutive effect that could cause our share price to decline.

We  have  a  number  of  convertible  securities  outstanding,  including  Contingent  Value  Rights  ("CVRs"),  Convertible  Notes  and  warrants,  and  the  conversion  of  such  securities  into  shares  of  our
common stock could have a material dilutive effect that could cause our share price to decline.

The Convertible Notes are convertible into shares of common stock at any time at the option of the holder subject to certain conditions. We have reserved a sufficient number of shares of common
stock  for  issuance  upon  conversion  of  the  Convertible  Notes,  CVRs  and  warrants.  During  the  second  half  of  2020,  $39.1  million  in  principal  amount  of  Convertible  Notes  were  converted  into
13,171,791 shares of our common stock. As of December 31, 2023, the outstanding balance of Convertible Notes was $48.8 million. If

57

 
 
Table of Contents

any more or all of the Convertible Notes are converted into shares of common stock, our existing shareholders will experience immediate dilution of voting rights and the price of shares of our
common stock may decline. Furthermore, the perception that such dilution could occur may cause the market price of our common stock to decline. At any time before the close of business on the
second scheduled trading day immediately before the maturity date, holders of Convertible Notes may convert their Convertible Notes at their option into shares of our common stock, together, if
applicable, with cash in lieu of any fractional share, at the then-applicable conversion rate. The conversion rate for the Convertible Notes is 326.7974 shares of our common stock per $1,000 principal
amount of Convertible Notes, which represents an initial conversion price of approximately $3.06 per share of common stock, and is subject to adjustment under the terms of the Convertible Notes. In
the  event  of  certain  circumstances,  we  will  increase  the  conversion  rate,  provided  that  the  conversion  rate  will  not  exceed  367.6470  shares  of  our  common  stock  per  $1,000  principal  amount  of
Convertible Notes in the case of the 2025 Convertible Notes and 549.4505 shares of our common stock per $1,000 principal amount of Convertible Notes in the case of the 2028 Convertible Notes.
As  a  result  of  the  conversion  rates  of  the  Convertible  Notes  adjusting  upward  upon  the  occurrence  of  certain  events,  our  existing  shareholders  may  experience  more  dilution  if  any  or  all  of  the
Convertible Notes are converted into shares of common stock after the adjusted conversion rate became effective.

Each CVR is worth up to $1.00, payable to CVR holders if future performance milestones are achieved, and settleable in cash, common stock, or a combination of cash and common stock, at our sole
election. If the performance milestones are met and we elect to pay the CVR consideration in common stock, it could have a dilutive effect to our earnings per share and cause our share price to
decline. As of December 31, 2023, a performance milestone worth $0.25 has been achieved, and performance milestones worth $0.50 remain outstanding.

Upon  completion  of  the  acquisition  of  Strongbridge,  each  outstanding  and  unexercised  Strongbridge  warrant  (except  private  placement  warrants)  was  assumed  by  the  Company  such  that,  upon
exercise, the applicable holders will have the right to have delivered to them the reference property (as such term is defined in the Strongbridge assumed warrants). We also assumed the outstanding
and unexercised Strongbridge private placement warrants and they expired in June 2022. The conversion of these assumed Strongbridge warrants (except the private placement warrants) into shares
of our common stock could have a dilutive effect that could cause our share price to decline.

We do not anticipate paying any cash dividends in the foreseeable future, and accordingly, our stockholders’ ability to achieve a return on their investment will depend on appreciation in the
price of our common stock.

We do not anticipate declaring any cash dividends to holders of our common stock in the foreseeable future. In addition, under our Hayfin Loan Agreement, we are generally restricted from paying
any dividends or making any distributions on account of our capital stock. Our ability to pay cash dividends also may be prohibited by future loan agreements. Consequently, investors must rely on
sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment. Investors seeking cash dividends should not invest in our
common stock.

Risks Related to Tax

We might not be able to utilize a significant portion of our net operating loss carryforwards and research and development tax credit carryforwards.

As  of  December  31,  2023,  we  had  federal  net  operating  loss  carryforwards  of  $494.3  million  and  various  state  net  operating  loss  carryforwards  of  $352.2  million.  If  not  utilized,  the  federal  net
operating losses generated in taxable years beginning on or before December 31, 2017 will expire in 2037, and these net operating loss carryforwards could expire unused and be unavailable to offset
future income tax liabilities. Federal net operating losses generated in taxable years beginning after December 31, 2017 can be carried forward indefinitely; however, such net operating losses may
only offset up to 80% of taxable income in taxable years beginning after December 31, 2023. As of December 31, 2023, we had $6.9 million and $3.7 million of federal and state income tax credits,
respectively, to reduce future tax liabilities. If not utilized, the $6.9 million in federal income tax credits will begin to expire in 2038, and the $3.7 million of state economic development and research
and development credits will begin to expire in 2024. In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended ("Code") and corresponding provisions of state law,
if a corporation undergoes an "ownership change," which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use
its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income may be limited. Our existing net operating losses or credits may be subject to
limitations arising from previous ownership changes, and if we undergo future ownership changes, many of which may be outside of our control, our ability to utilize our net operating losses or
credits could be further limited by Sections 382 and 383 of the Code. Accordingly, we may not be able to utilize a material portion of our net operating losses or credits.

Changes in tax law may adversely affect us or our investors.

The  rules  dealing  with  the  United  States  federal,  state  and  local  income  taxation  are  constantly  under  review  by  persons  involved  in  the  legislative  process  and  by  the  Internal  Revenue  Service
("IRS") and the United States Treasury Department. Changes to tax laws (which changes may have retroactive application) could adversely affect us or holders of our common stock. For example,
under Section 174 of the Code, in taxable years beginning after December 31, 2021, expenses that are incurred for research and development in the United States will be capitalized and amortized,
which may have an adverse effect on our cash flow. In recent years, many such changes have been made, and changes are likely to continue to occur in the future. It cannot be predicted whether,
when, in what form or with what effective dates tax laws, regulations and rulings may be enacted, promulgated or issued, which could result in an increase in our or our shareholders’ tax liability or
require changes in the manner in which we operate in order to minimize or mitigate any

adverse effects of changes in tax law.

Risks Related to our Indentures for our Convertible Notes, Charter and Bylaws

Provisions  in  the  Indentures  for  our  Convertible  Notes  and  corporate  charter  documents  and  under  Delaware  law  may  prevent  or  frustrate  attempts  by  our  stockholders  to  change  our
management or hinder efforts to acquire a controlling interest in us.

Provisions  in  our  corporate  charter  and  our  bylaws  may  discourage,  delay  or  prevent  a  merger,  acquisition  or  other  change  in  control  of  us  that  stockholders  may  consider  favorable,  including
transactions in which you might otherwise receive a premium for your shares. These provisions could also limit the price that investors might be willing to pay in the future for shares of our common
stock, thereby depressing the market price of our common stock. In addition, because our board of directors is responsible for appointing the members of our management team, these provisions may
frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors. Among
other things, these provisions:















establish a classified board of directors such that all members of the board are not elected at one time; allow the authorized number of our directors to be changed only by resolution of
our board of directors; and limit the manner in which stockholders can remove directors from the board;
establish advance notice requirements for nominations for election to the board of directors or for proposing matters that can be acted on at stockholder meetings;
require that stockholder actions must be effected at a duly called stockholder meeting and prohibit actions by our stockholders by written consent;
limit who may call a special meeting of stockholders;
authorize our board of directors to issue preferred stock without stockholder approval, which could be used to institute a "poison pill" that would work to dilute the stock ownership of a
potential hostile acquirer, effectively preventing acquisitions that have not been approved by our board of directors;
require the approval of the holders of at least two-thirds of the votes that all our stockholders would be entitled to cast to amend or repeal certain provisions of our charter or bylaws;
and
establish a Delaware Forum Provision (as defined below) or a Federal Forum Provision (as defined below).

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the General Corporation Law of the State of Delaware, which prohibits a person who owns
in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our
outstanding voting stock, unless the merger or combination is approved in a prescribed manner. This could discourage, delay or prevent someone from acquiring us or merging with us, whether or not
it is desired by, or beneficial to, our stockholders. This could also have the effect of discouraging others from making tender offers for our common stock, including transactions that may be in our
stockholders’ best interests. These provisions may also prevent changes in our management or limit the price that investors are willing to pay for our stock.

In addition, certain provisions in the Indentures governing our Convertible Notes could make a third-party attempt to acquire us more difficult or expensive. For example, if a takeover constitutes a
fundamental change, then noteholders will have the right to require us to repurchase their notes for cash. In addition, if a takeover constitutes a make-whole fundamental change, then we may be
required  to  temporarily  increase  the  conversion  rate.  In  either  case,  and  in  other  cases,  our  obligations  under  the  notes  and  the  indentures  could  increase  the  cost  of  acquiring  us  or  otherwise
discourage a third party from acquiring us or removing incumbent management, including in a transaction that noteholders or holders of our common stock may view as favorable.

Our bylaws designate certain courts as the sole and exclusive forums for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’
ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees and may discourage such lawsuits with respect to such claims.

Our amended and restated bylaws provide that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for any state
law claim for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of, or a claim based on, a breach of or based on a fiduciary duty owed by any of our
current  or  former  directors,  officers  and  employees  to  us  or  our  stockholders,  (iii)  any  action  asserting  a  claim  arising  pursuant  to  any  provision  of  the  Delaware  General  Corporation  Law,  our
certificate  of  incorporation  or  our  bylaws,  or  (iv)  any  action  asserting  a  claim  that  is  governed  by  the  internal  affairs  doctrine,  in  each  case  subject  to  the  Court  of  Chancery  having  personal
jurisdiction over the indispensable parties named as defendants therein (the "Delaware Forum Provision"). The Delaware Forum Provision will not apply to any causes of action arising under the
Securities  Act  or  the  Securities  Exchange  Act  of  1934,  as  amended.  In  addition,  our  amended  and  restated  bylaws  further  provide  that  the  federal  district  courts  of  the  United  States  will  be  the
exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act (the "Federal Forum Provision").

This  forum  selection  provision  may  limit  a  shareholder’s  ability  to  bring  a  claim  in  a  judicial  forum  that  it  finds  favorable  or  cost-efficient  for  disputes  with  us  or  any  of  our  directors,  officers,
employees or agents, which may discourage such lawsuits, or increase the costs to a shareholder of bringing such lawsuits, against us and such persons.

59

Table of Contents

The enforceability of forum selection provisions in other companies’ articles of incorporation, bylaws or similar governing documents has been challenged in legal proceedings, and it is possible that
in connection with any action a court could find the forum selection provisions contained in our bylaws to be inapplicable or unenforceable in such action. If a court were to find these forum selection
provisions  inapplicable  or  unenforceable,  we  may  incur  additional  costs  associated  with  resolving  such  matters  in  other  jurisdictions,  which  could  adversely  impact  our  operating  or  financial
condition or performance.

General Risk Factors

If we experience significant disruptions in our information technology systems, our business may be adversely affected.

We depend on our information technology systems for the efficient functioning of our business, including accounting, data storage, compliance, purchasing and inventory management. Our current
systems  are  not  fully  redundant.  We  may  experience  difficulties  in  implementing  some  upgrades  which  would  impact  our  business  operations  or  experience  difficulties  in  operating  our  business
during the upgrade, either of which could disrupt our operations, including our ability to timely ship and track product orders, project inventory requirements, manage our supply chain and otherwise
adequately  service  our  customers.  In  the  event  we  experience  significant  disruptions  of  our  information  technology  systems,  we  may  not  be  able  to  repair  our  systems  in  an  efficient  and  timely
manner. Accordingly, such events may disrupt or reduce the efficiency of our entire operation and have a material adverse effect on our results of operations and cash flows.

We are increasingly dependent on sophisticated information technology for our infrastructure. Our information systems require an ongoing commitment of significant resources to maintain, protect
and enhance existing systems. Despite our implementation of security measures, our information systems are vulnerable to damages from computer viruses, natural disasters, unauthorized access,
cyber-attack, including ransomware, and other similar disruptions. Any system failure, accident or cybersecurity incident, compromise, or breach could result in disruptions to our operations. For
example, third parties may attempt to hack into systems and may obtain our proprietary information or other sensitive information, which could cause significant damage to our reputation, lead to
claims or government enforcement action against the Company and ultimately harm our business. To the best of our knowledge, no risks from cybersecurity threats, including those resulting from
any  previous  cybersecurity  incidents,  have  materially  affected,  and  we  do  not  believe  they  are  reasonably  likely  to  materially  affect,  us,  our  business  strategy,  results  of  operations,  or  financial
condition.  We  may  expend  significant  resources  to  try  to  protect  against  these  threats  to  our  Systems.  In  addition,  a  cybersecurity  incident  involving  one  of  our  customers,  including  an  incident
involving their customers or vendors, could materially affect our business strategy, results of operations, or financial condition if our customers or their customers or vendors are unable to conduct
their regular operations. For example, in February 2024, UnitedHealth Group announced that its Change Healthcare information technology systems that process payment claims for payors was being
taken offline for an undefined period due to a cybersecurity incident, such incident could reduce demand for our products and harm our revenues as physician providers are unable to use such systems
to submit electronic prescriptions and pharmacies are unable to fill electronic prescriptions for our products.

If products liability lawsuits are brought against us, our business may be harmed, and we may be required to pay damages that exceed our insurance coverage.

We may face liability claims related to the use or misuse of our products and product candidates. These claims may be expensive to defend and may result in large judgments against us. During the
course of treatment, patients using our products and product candidates could suffer adverse medical effects for reasons that may or may not be related to our products and product candidates. Any of
these events could result in a claim of liability. Any such claims against us, regardless of their merit, could result in significant costs to defend or awards against us that could materially harm our
business, financial condition or results of operations. In addition, any such claims against us could result in a distraction to management, decreased demand for our products, an adverse effect on our
public reputation, and/or difficulties in commercializing our products. To date, we have not received notice of any products liability claims against us. We maintain total products liability insurance
coverage of $15.0 million.

Although we maintain products liability insurance for claims arising from the use of our products after FDA approval and for claims arising from the use of our product candidates in clinical trials
prior to FDA approval at levels that we believe are appropriate, we may not be able to maintain our existing insurance coverage or obtain additional coverage on commercially reasonable terms for
the use of our other products and product candidates in the future. Also, our insurance coverage and resources may not be sufficient to satisfy any liability resulting from products liability claims,
which could materially harm our business, financial condition or results of operations. In addition, we have in the past and may in the future agree to indemnify counterparties from losses arising from
claims relating to the products, processes or services made, used, sold or performed.

Should our obligation under an indemnification provision exceed applicable insurance coverage or if we were denied insurance coverage, our business, financial condition and results of operations
could be adversely affected. Similarly, if we are relying on a collaborator to indemnify us and the collaborator is denied insurance coverage or the indemnification obligation exceeds the applicable
insurance coverage and the collaborator does not have other assets available to indemnify us, our business, financial condition and results of operations could be adversely affected.

Products  liability  claims  could  result  in  an  FDA  or  other  regulatory  authority  investigation  into  the  safety  or  efficacy  of  our  products,  our  manufacturing  processes  and  facilities,  our  marketing
programs, our internal safety reporting systems or our staff conduct. A regulatory authority investigation could also potentially lead to a recall of our products or more serious enforcement actions,
limitations on the indications for which they may be used, or suspension or withdrawal of approval. Products liability claims could also result in investigation, prosecution or enforcement action by
the DOJ or other federal or state government agencies.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, stockholders
could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our common stock.

Effective internal controls over financial reporting are necessary for us to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent
fraud. Any failure to implement required new or improved controls, or difficulties encountered in their implementation could cause us to fail to meet our reporting obligations. In addition, any testing
by us conducted in connection with Section 404 of the Sarbanes-Oxley Act, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal
controls  over  financial  reporting  that  are  deemed  to  be  material  weaknesses  or  that  may  require  prospective  or  retroactive  changes  to  our  financial  statements  or  identify  other  areas  for  further
attention or improvement. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which could have a negative effect on the trading price of our
stock.

We are required to disclose changes made in our internal controls and procedures on a quarterly basis, and our management is required to assess the effectiveness of these controls annually. An
independent assessment of the effectiveness of our internal controls over financial reporting could detect problems that our management's assessment might not. Undetected material weaknesses in
our internal controls over financial reporting could lead to financial statement restatements and require us to incur the expense of remediation.

As a result of being a public company, we will continue to incur significant additional costs which may adversely affect our operating results and financial condition.

We expect to continue to incur costs associated with corporate governance requirements, including requirements under the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, as
well as rules implemented by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, the SEC and The Nasdaq Global Select Market. These rules and
regulations have increased our accounting, legal and financial compliance costs and make some activities more time consuming and costly. In addition, we will continue to incur costs associated with
our public company reporting requirements, and we expect those costs may increase in the future, , particularly since we determined we have ceased to qualify as an “emerging growth company,” as
defined in the Jumpstart Our Business Startups Act enacted in April 2012, as of December 31, 2023 and as a “smaller reporting company” as of June 30, 2023. For example, we are no longer able to
take advantage of certain exemptions and relief from various reporting requirements that are applicable to public companies that are not “emerging growth companies”. In particular and amongst
other requirements, we are required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley and are subject to the full disclosure obligations regarding executive
compensation in our periodic reports and proxy statements which rules and regulations have increased our legal and financial compliance costs relative to prior years and will make some activities
more time-consuming and costly. We may also need to hire more employees in the future or engage additional outside consultants to comply with these requirements, which will increase our costs
and expenses.

During  the  course  of  our  ongoing  review  and  testing  of  our  internal  controls,  we  may  identify  deficiencies  and  may  incur  significant  costs  to  remediate  such  deficiencies,  including  material
weaknesses, if any, that we identify through these efforts. We cannot predict or estimate the amount of additional costs we may incur or the timing of such costs.

New laws and regulations, as well as changes to existing laws and regulations affecting public companies, including the provisions of the Sarbanes-Oxley Act, the Dodd-Frank Act and rules adopted
by the SEC and The Nasdaq Global Select Market, would likely result in increased costs to us as we respond to their requirements, which may adversely affect our operating results and financial
condition.

Securities analysts may publish inaccurate or unfavorable research or reports about our business or may publish no information at all, which could cause our stock price or trading volume to
decline.

The trading market for our common stock is influenced by the research and reports that industry or financial analysts publish about us and our business. We do not control these analysts. Analysts
who publish information about our common stock may have relatively little experience covering our company, which could affect their ability to accurately forecast our results and could make it
more likely that we fail to meet their estimates. If any of the analysts who cover us provide inaccurate or unfavorable research or issue an adverse opinion regarding our stock price, our stock price
could decline. If one or more of these analysts cease coverage of our company or fail to publish reports covering us regularly, we could lose visibility in the market, which in turn could cause our
stock price or trading volume to decline.

Our data collection and processing activities are governed by restrictive regulations governing the use, processing and, in certain jurisdictions, cross-border transfer of personal information.

We may be subject to the United States federal and state, European, UK and other foreign data protection laws and regulations (i.e., laws and regulations that address privacy and data security). We
have  personnel  located  in  Ireland  and  have  conducted  and  may  in  the  future  conduct  clinical  trials  in  the  European  Economic  Area  ("EEA")  and/or  the  UK  subjecting  us  to  additional  privacy
restrictions and data protection requirements. The collection and use of personal data (including health data) in the EEA and the UK are governed by the provisions of the EU General Data Protection
Regulation ("EU GDPR") as well as other national data protection legislation in force in relevant Member States, with respect to the EEA, and the UK General Data Protection Regulation (the "UK
GDPR," together with the EU GDPR the "GDPR") and the UK Data Protection Act 2018 with respect to the UK. These laws impose a broad range of strict requirements on companies subject to the
GDPR, such as including requirements relating to having legal bases for processing personal data relating to identifiable individuals and transferring such information outside the EEA or the UK,
providing details to those individuals regarding the processing of their personal data, implementing safeguards to keep personal data secure, having data

61

Table of Contents

processing agreements with third parties who process personal data, providing information to individuals regarding data processing activities, responding to individuals’ requests to exercise their
rights  in  respect  of  their  personal  data,  obtaining  consent  of  the  individuals  to  whom  the  personal  data  relates,  reporting  security  and  privacy  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 may impose additional
responsibility and liability in relation to personal data that we process and we may be required to put in place additional mechanisms ensuring compliance with the EEA and UK data protection
regimes. This may be onerous and adversely affect our business, financial condition, results of operations and prospects.

The GDPR prohibits the international transfer of personal data to countries outside of the EEA or the UK ("third countries") which are not deemed as adequate for the transfers of personal data by
competent authorities, unless a derogation exists or adequate safeguards (for example, the European Commission approved Standard Contractual Clauses ("EU SCCs") and the UK International Data
Transfer Agreement/Addendum ("UK IDTA")) are implemented in compliance with EEA and UK data protection laws. Where relying on the EU SCCs or UK IDTA for data transfers, we may also be
required to carry out transfer impact assessments on transfers made pursuant to the EU SCCs and the UK IDTA, on a case-by-case basis to ensure the law in the data importer’s country and the data
importer  can  ensure  sufficient  guarantees  for  safeguarding  the  personal  data  under  GDPR.  This  assessment  includes  assessing  whether  third  party  vendors  can  also  ensure  these  guarantees.  The
international transfer obligations under the EEA and UK data protection regimes will require significant effort and cost and may result in us needing to make strategic considerations around where
EEA and UK personal data is located and which service providers we can utilize for the processing of EEA and UK personal data. Any inability to transfer personal data from the EEA and UK to the
United States in compliance with data protection laws may impede our ability to conduct trials and may adversely affect our business and financial position.

The EU commission has adopted its adequacy decision for the EU-U.S. Data Privacy Framework ("Framework") agreed with the U.S., which entered into force on July 11, 2023. This Framework
provides that the protection of personal data transferred between the EEA and the U.S. is comparable to that offered in the EEA. This Framework provides a further avenue to ensure transfers to the
U.S. are carried out in line with GDPR. Where we rely on the Framework as a transfer mechanism for international transfers of personal data to the U.S., the Framework’s validity could be challenged
and the Framework subsequently invalidated as a mechanism for transferring personal data to the U.S. like its predecessor Privacy Shield and Safe Harbor frameworks.

Although the UK is regarded as a third country under the EU’s GDPR, the European Commission has issued an adequacy decision recognizing the UK as providing adequate protection under the EU
GDPR and, therefore, transfers of personal data originating in the EEA to the UK remain unrestricted. Likewise, the UK government has confirmed that personal data transfers from the UK to the
EEA remain free flowing. The UK government has introduced a Data Protection and Digital Information Bill ("UK Bill") into the UK legislative process. The aim of the UK Bill is to reform the
UK’s data protection regime following Brexit. If passed, the final version of the UK Bill may have the effect of further altering the similarities between the UK and EEA data protection regime and
threaten the UK adequacy decision from the European Commission.

The potential of the respective provisions and enforcement of the EU GDPR and UK GDPR further diverging in the future creates additional regulatory challenges and uncertainties for us. The lack
of clarity on future UK laws and regulations and their interaction with EU laws and regulations could add legal risk, uncertainty, complexity and cost to our handling of European personal data and
our privacy and data security compliance programs and could require us to implement different compliance measures for the UK and the EEA.

In addition, EEA Member States have adopted national laws to implement the EU GDPR that may partially deviate from the EU GDPR and competent authorities in the EEA Member States may
interpret the EU GDPR obligations slightly differently from country to country. Therefore, we do not expect to operate in a uniform legal landscape in the EEA.

If we are investigated by a European or UK data protection authority, we may face fines and other penalties, including bans on processing and transferring personal data. EEA and UK data protection
authorities have the power to impose administrative fines for violations of the GDPR of up to a maximum of €20 (£17.5 under the UK GDPR) million or 4% of our total worldwide global turnover
for  the  preceding  fiscal  year,  whichever  is  higher,  and  violations  of  the  GDPR  may  also  lead  to  damages  claims  by  data  controllers  and  data  subjects.  Such  penalties  are  in  addition  to  any  civil
litigation claims by data controllers, clients, and data subjects. As such, we will need to take steps to cause our processes to continue to be compliant with the applicable portions of the GDPR, but we
cannot assure you that we will be able to implement changes in a timely manner or without significant disruption to our business, or that such steps will be effective, and we may face the risk of
liability under the GDPR.

Many jurisdictions outside of Europe where we may do business or conduct trials in the future are also considering and/or have enacted comprehensive data protection legislation. In addition, we also
continue to see jurisdictions imposing data localization laws. These and similar regulations may interfere with our intended business activities, inhibit our ability to expand into those markets, require
modifications to our products or services or prohibit us from continuing to offer services or conduct trials in those markets without significant additional costs.

Artificial intelligence presents risks and challenges that can impact our business including by posing security risks to our confidential information, proprietary information, and personal data.

Issues in the use of artificial intelligence, combined with an uncertain regulatory environment, may result in reputational harm, liability, or other adverse consequences to our business operations. As
with many technological innovations, artificial intelligence presents risks and challenges that could impact our business. Our vendors may incorporate generative artificial intelligence tools into their
offerings without disclosing this use to us, and the providers of these generative artificial intelligence tools may not meet existing

62

Table of Contents

or rapidly evolving regulatory or industry standards with respect to privacy and data protection and may inhibit our or our vendors’ ability to maintain an adequate level of service and experience. If
our  vendors,  or  our  third-party  partners  experience  an  actual  or  perceived  breach  or  privacy  or  security  incident  because  of  the  use  of  generative  artificial  intelligence,  we  may  lose  valuable
intellectual property and confidential information and our reputation and the public perception of the effectiveness of our security measures could be harmed. Further, bad actors around the world use
increasingly  sophisticated  methods,  including  the  use  of  artificial  intelligence,  to  engage  in  illegal  activities  involving  the  theft  and  misuse  of  personal  information,  confidential  information,  and
intellectual property. Any of these outcomes could damage our reputation, result in the loss of valuable property and information, and adversely impact our business.

Our employees, independent contractors, consultants, collaborators and CROs may engage in misconduct or other improper activities, including non-compliance with regulatory standards and
requirements, which could cause significant liability for us and harm to our reputation.

We are exposed to the risk that our employees, independent contractors, consultants, collaborators and CROs may engage in fraud or other misconduct, including intentional failures to comply with
FDA regulations or similar regulations of comparable non-United States regulatory authorities, to provide accurate information to the FDA or comparable non-United States regulatory authorities, to
comply with manufacturing standards we have established, to comply with federal and state healthcare fraud and abuse laws and regulations and similar laws and regulations established and enforced
by comparable non-United States regulatory authorities, to report financial information or data accurately or to disclose unauthorized activities to us. Such misconduct could also involve the improper
use or misrepresentation of information obtained in the course of clinical trials, creating fraudulent data in our preclinical studies or clinical trials or illegal misappropriation of product materials,
which could result in regulatory sanctions and serious harm to our reputation. It is not always possible to identify and deter misconduct, and the precautions we take to detect and prevent this activity
may  not  be  effective  in  controlling  unknown  or  unmanaged  risks  or  losses  or  in  protecting  us  from  governmental  investigations  or  other  actions  or  lawsuits  stemming  from  a  failure  to  be  in
compliance with such laws, standards or regulations. Additionally, we are subject to the risk that a person or government could allege such fraud or other misconduct, even if none occurred. If any
such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business and results of operations,
including the imposition of significant fines or other sanctions.

Global economic uncertainty and weakening product demand caused by political instability, changes in trade agreements and conflicts, such as the conflicts between Russia and Ukraine and
Israel and Hamas, or other events could adversely affect our business and financial performance.

Economic uncertainty in various global markets caused by political instability and conflict and economic challenges has in the past resulted, and may continue to result, in weakened demand for our
products. Political developments impacting government spending and international trade, including potential government shutdowns and trade disputes and tariffs, may negatively impact markets and
cause weaker macro-economic conditions. The effects of these events may continue due to potential United States government shutdowns and the transition in administrations, and the United States’
ongoing trade disputes with China and other countries. In addition, the current military conflicts between Russia and Ukraine and Israel and Hamas could disrupt or otherwise adversely impact our
operations and related sanctions, export controls or other actions that may be initiated by nations including the United States, the EU, Russia or countries or actors in the Middle East (e.g., potential
cyberattacks, disruption of energy flows, etc.) could adversely affect our business and/or our supply chain or those of our third party service providers. The United States and other countries could
take other actions that may adversely affect our business should the conflicts further escalate. It is not possible to predict the broader consequences of these conflicts, which could include further
sanctions,  embargoes,  regional  instability,  prolonged  periods  of  higher  inflation,  international  trade  disruptions,  supply  disruptions,  geopolitical  shifts,  and  adverse  effects  on  macroeconomic
conditions, currency exchange rates, and financial markets, all of which could have a material adverse effect on our business, financial condition, and results of operations. The continuing effect of
any or all of these events could adversely impact demand for our products, harm our operations and weaken our financial results.

Our operations are subject to the effects of a rising rate of inflation.

The  United  States  has  recently  experienced  historically  high  and  fluctuating  levels  of  inflation.  If  the  inflation  rate  continues  to  increase,  for  example  due  to  increases  in  the  costs  of  labor  and
supplies, or remain at a historically high rate, it will affect our expenses, such as employee compensation, supply costs and research and development expenses. In addition, elevated and fluctuating
inflation and increasing interest rates has contributed to potential economic uncertainty in the larger economy. To the extent inflation continues to result in rising interest rates and has other adverse
effects on the market, it may adversely affect our financial condition and results of operations.

We maintain our cash at financial institutions, often in balances that exceed federally-insured limits. Adverse developments affecting the financial services industry, such as actual events or
concerns  involving  liquidity,  defaults,  or  non-performance  by  financial  institutions  or  transactional  counterparties,  could  adversely  affect  the  Company’s  current  and  projected  business
operations, ability to pay operational expenses or make other payments, and its financial condition and results of operations.

Our cash held in non-interest bearing and interest-bearing accounts exceeds the Federal Deposit Insurance Corporation ("FDIC") limits and is predominantly held at one institution, Wells Fargo Bank,
N.A. If such banking institution or any future banking institutions where we maintain our cash were to fail, we could lose all or a portion of those amounts held in excess of such insurance limits. For
example, the recent closures of Silicon Valley Bank, where we maintained a portion of our cash, Signature Bank and First

63

Table of Contents

Republic Bank and their placement into receivership with the FDIC created bank-specific and broader financial institution liquidity risk and concerns. Although the Department of the Treasury, the
Federal Reserve, and the FDIC jointly released a statement that depositors at Silicon Valley Bank and Signature Bank would have access to their funds, even those in excess of the standard FDIC
insurance limits, future adverse developments with respect to specific financial institutions or the broader financial services industry, including concerns or rumors about any events of these kinds or
similar risks, may lead to market-wide liquidity shortages and the FDIC may elect not to make all account holders whole. The failure of any bank in which we deposit our funds could reduce the
amount of cash we have available for our operations or delay our ability to access such funds and could have a material adverse effect on our business and financial condition.

In  addition,  investor  concerns  regarding  the  U.S.  or  international  financial  systems  could  result  in  less  favorable  commercial  financing  terms,  including  higher  interest  rates  or  costs  and  tighter
financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Any
decline in available funding or access to our cash and liquidity resources could, among other risks, adversely impact our ability to meet our operating expenses, financial obligations or fulfill our other
obligations, result in breaches of our financial and/or contractual obligations or result in violations of federal or state wage and hour laws. Any of these impacts, or any other impacts resulting from
the factors described above or other related or similar factors not described above, could have material adverse impacts on our liquidity and our current and/or projected business operations and
financial condition and results of operations.

Finally, any further deterioration in the macroeconomic economy or financial services industry could lead to losses or defaults by our suppliers, which in turn, could have a material adverse effect on
our current and/or projected business operations and results of operations and financial condition. For example, a customer may fail to make payments when due, default under their agreements with
us or others, become insolvent or declare bankruptcy, or a supplier may determine that it will no longer deal with us as a customer. Any supplier bankruptcy or insolvency, or the failure of any
customer to make payments when due, or any breach or default by a supplier, or the loss of any significant supplier relationships, could result in material losses to the Company and may have a
material adverse impact on our business.

Our business could be negatively impacted by environmental, social and corporate governance matters or our reporting of such matters.

There is an increasing focus from certain investors, employees, partners, and other stakeholders concerning environmental, social and corporate governance ("ESG") matters. For instance, the SEC
has recently proposed climate change and ESG reporting requirements, which, if approved, would significantly increase our costs, divert management resources and attention and require us to expend
significant  time  and  resources,  which  could  have  an  adverse  effect  on  our  business,  financial  condition  and  results  of  operations.  If  our  ESG  practices  fail  to  meet  investor,  customer,  consumer,
employee or other stakeholders’ evolving expectations and standards in areas such as environmental stewardship, Board of Directors and employee diversity, human capital management, corporate
governance and transparency, our reputation could be negatively impacted, which could have a material adverse effect on our business or financial condition.

ITEM 1B. UNRESOLVED STAFF COMMENTS

We have no unresolved written comments regarding our periodic or current reports from the staff of the United States Securities and Exchange Commission ("SEC").

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

In  the  normal  course  of  business,  we  collect  and  store  personal  information  and  other  sensitive  information,  including  proprietary  and  confidential  business  information,  intellectual  property,
information regarding patients, sensitive third-party information and employee information. To protect this information, we have implemented a framework that is designed to identify, assess, and
mitigate cybersecurity threats.

We use managed detection and response services to monitor our network infrastructure and associated endpoints for possible cybersecurity threats. In addition, we engage third parties to perform
penetration  testing  and  to  assess  the  effectiveness  of  our  cybersecurity  practices.  We  conduct  a  cybersecurity  risk  assessment  by  identifying  critical  assets,  recognizing  potential  threats  and
vulnerabilities,  and  implementing  strategies  to  mitigate  these  cybersecurity  risks  and  their  possible  impacts.  We  also  actively  engage  with  key  vendors  and  industry  participants  as  part  of  our
continuing efforts to evaluate and enhance the effectiveness of our information security policies and procedures.

We have established a cybersecurity incident response plan and provide cybersecurity training to our employees and monitor their activity for adherence to our security protocols.

No  risks  from  cybersecurity  threats  have  occurred  that  have  affected  our  business  strategy,  results  of  operations,  or  financial  condition.  See  “Risk  Factors  -  General  Risk  Factors”  for  additional
information.

Governance

64

Table of Contents

Our information security program is overseen by our Executive Director of Information Technology (“IT”). The Executive Director of IT reports to the Chief Financial Officer and oversees the team
responsible for leading enterprise-wide cybersecurity strategy, policy, standards, and processes. The Executive Director of IT possesses over twenty-five years of experience in information technology
and approximately ten years in cybersecurity risk management.

Our  Board  of  Directors  (“Board”)  has  responsibility  for  oversight  of  risk  management  and,  pursuant  to  the  Audit  Committee  Charter,  has  delegated  to  our  Audit  Committee  oversight  of  our
cybersecurity risk management program. The Executive Director of IT provides reports to the Audit Committee at least annually as well as the Chief Executive Officer and other members of our
senior management as appropriate. These reports include updates on the Company’s cyber risks and threats, the status of projects to strengthen our information security systems, assessments of the
information security program, and the emerging threat landscape. Our program is regularly evaluated by internal and external security professionals with the results of those reviews reported to senior
management and the Board.

ITEM 2. PROPERTIES

Our principal office and development laboratory site are both located at 1375 West Fulton Street, Chicago, Illinois and occupy approximately 87,032 square feet of leased space. The term will expire
on March 31, 2036. We believe that our offices are suitable and adequate to meet our needs.

ITEM 3. LEGAL PROCEEDINGS

We  are  not  currently  subject  to  any  material  legal  proceedings.  From  time  to  time,  we  may  be  subject  to  various  legal  proceedings  and  claims  that  arise  in  the  ordinary  course  of  our  business
activities. Although the results of litigation and claims cannot be predicted with certainty, as of the date of this report, we do not believe we are party to any claim or litigation the outcome of which, if
determined adversely to us, would individually or in the aggregate be reasonably expected to have a material adverse effect on our business. Regardless of the outcome, litigation can have an adverse
impact on us because of defense and settlement costs, diversion of management resources and other factors.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing elsewhere in this
Annual Report on Form 10-K. This discussion contains forward-looking statements that involve significant risks and uncertainties. Our actual results could differ materially from those discussed in
these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those set forth in Part I, Item 1A. Risk Factors, of this Annual Report on
Form  10-K.  This  discussion  and  analysis  compares  2023  results  to  2022.  For  discussion  and  analysis  that  compares  2022  results  to  2021,  see  Item  7.  Management's  Discussion  and  Analysis  of
Financial Condition and Results of Operations in Part II, Item 7. of this Annual Report on Form 10-K for the year ended December 31, 2022.

Overview

As used herein, the "Company", "Xeris", "we" or "our" refers to Xeris Biopharma Holdings, Inc. ("Xeris Biopharma"). Throughout this document, unless otherwise noted, references to Gvoke include
Gvoke PFS, Gvoke HypoPen, Gvoke Kit and Ogluo.

We  are  focused  on  building  an  innovative,  self-sustaining,  growth-oriented  biopharmaceutical  company  committed  to  improving  patients’  lives  by  developing  and  commercializing  clinically
meaningful products across a range of therapies. We are uniquely positioned to achieve this through our three commercial products and our proprietary formulation science (XeriSol and XeriJect),
which generates partnerships and enhances our product candidates.

Patents

We currently own 170 patents issued globally, including composition of matter patents covering our ready-to-use glucagon formulation that expire in 2036. Included in the total patents, we have 60
granted  patents  globally  related  to  our  platform  technologies  and  8  patents  granted  in  the  United  States  and  listed  in  the  United  States  FDA  Orange  Book  covering  proprietary  formulations  of
levoketoconazole (the active pharmaceutical ingredient in Recorlev) and the uses of such formulations in treating certain endocrine-related diseases and syndromes. The latter includes United States
Patent Nos. 11,020,393, 11,278,547 and 11,903,940, which were granted on June 1, 2021, March 22, 2022, and February 22, 2024, respectively, and which provide patent protection through 2040 for
the use of Recorlev in the treatment of certain patients with persistent or recurrent Cushing’s syndrome.

Financing

We have funded our operations to date primarily with proceeds from the sale of our preferred and common stock and debt financing.

For the years ended December 31, 2023 and 2022, we reported net losses of $62.3 million and $94.7 million, respectively. We have not been profitable since inception, and, as of December 31, 2023,
our accumulated deficit was $617.0 million. In the near term, we expect to continue to incur significant expenses, operating losses and net losses as we:









continue our marketing and selling efforts related to commercialization of Gvoke, Recorlev and Keveyis;
continue our research and development efforts;
continue to operate as a public company; and
continue to fund our operations with an increased cost of borrowing due to a higher interest rate environment and tighter
lending requirements.

We may continue to seek public equity and debt financing to meet our capital requirements. There can be no assurance that such funding may be available to us on acceptable terms, or at all, or that
we will be able to commercialize our product candidates, if approved. In addition, we may not be profitable even if we commercialize any of our product candidates.

Components of our Results of Operations

The following discussion sets forth certain components of the statement of operations of Xeris for years ended December 31, 2023 and 2022 as well as factors that impact those items.

Product revenue, net

Product revenue, net, represents gross product sales less estimated allowances for patient copay assistance programs, prompt payment discounts, payor rebates, chargebacks, service fees, and product
returns, all of which are recorded at the time of sale to the pharmaceutical wholesaler or other customer. We apply significant judgment and estimates in determining some of these allowances. If
actual results differ from our estimates, we make adjustments to these allowances in the period in which the actual

67

 
Table of Contents

results or updates to estimates become known. See "Critical Accounting Policies and Use of Estimates and Assumptions" for further information regarding the significant judgments and estimates
involved in the determination of product revenue, net.

Royalty, contract and other revenue

Royalty and contract revenue is recognized as earned in accordance with contract terms when it can be reasonably estimated and collectability is reasonably assured.

Cost of goods sold

Cost  of  goods  sold  primarily  includes  product  costs,  which  include  all  costs  directly  related  to  the  purchase  of  raw  materials,  charges  from  our  contract  manufacturing  organizations,  and
manufacturing  overhead  costs,  as  well  as  shipping  and  distribution  charges.  Cost  of  goods  sold  also  includes  losses  from  excess,  slow-moving  or  obsolete  inventory  and  inventory  purchase
commitments, if any. Manufacturing costs for Gvoke and Recorlev incurred prior to approval and initial commercialization were expensed as research and development expenses.

Research and development expenses

Research and development expenses consist of expenses incurred in connection with the discovery and development of our product candidates. We recognize research and development expenses as
incurred. Research and development expenses that are paid in advance of performance are capitalized until services are provided or goods are delivered. Research and development expenses include:















the cost of acquiring and manufacturing preclinical study and clinical trial materials and manufacturing costs related to commercial production and scale-up until a product is approved
and initially available for commercial sale;
expenses incurred under agreements with contract research organizations ("CROs") as well as investigative sites and consultants that conduct our preclinical studies and clinical trials;
personnel-related expenses, which include salaries, benefits and stock-based compensation;
laboratory materials and supplies used to support our research activities;
outsourced product development services;
expenses relating to regulatory activities, including filing fees paid to regulatory agencies; and
allocated expenses for facility-related costs.

Research and development activities are central to our business model. We expect to continue to incur significant research and development expenses as we advance our pipeline candidates and in
particular  plan  and  conduct  clinical  trials,  prepare  regulatory  filings  for  our  product  candidates,  and  utilize  internal  resources  to  support  these  efforts.  Our  research  and  development  costs  have
declined as compared to previous levels as a result of directing significant funding to our commercial activities.

Our research and development expenses may vary significantly over time due to uncertainties relating to the timing and results of our clinical trials, feedback received from interactions with the FDA
and the timing of regulatory approvals.

Selling, general and administrative expenses

Selling, general and administrative expenses consist primarily of compensation and related personnel costs, marketing and selling expenses, professional fees and facility costs not otherwise included
in research and development expenses.

Amortization of intangible assets

Amortization  of  intangible  assets  relates  to  the  amortization  of  our  products:  Keveyis  and  Recorlev.  These  two  intangible  assets  are  being  amortized  over  a  five-year  and  fourteen-year  period,
respectively, using the straight-line method.

Other income (expense)

Other income (expense) consists primarily of interest expense related to our convertible debt, Hayfin Loan Agreement, Oxford Loan Agreement, interest income earned on deposits and investments,
gains and losses on extinguishment of debt and lease remeasurement, and the change in fair value of our warrants and CVRs.

Income tax

We have incurred operating losses since inception and therefore do not have any taxable income. As of December 31, 2023, we had federal net operating loss carryforwards of $494.3 million and
various state net operating loss carryforwards of $352.2 million, $6.9 million in federal income tax credits will begin to expire in 2038, and the $3.7 million of state economic development and
research and development credits will begin to expire in 2024.

Gvoke net revenue increased by $14.5 million or 27.6% for the year ended December 31, 2023 compared to the year ended December 31, 2022. Gvoke prescriptions grew approximately 48.9% in
2023 compared to prior year. The growth in product demand was partially offset by a decrease in net pricing.

Keveyis net revenue increased by $7.5 million or 15.1% for the year ended December 31, 2023 compared to the year ended December 31, 2022. These increase was driven by higher patient demand
coupled with an increase in net pricing.

Recorlev net revenue increased by $22.1 million or 297.7% for the year ended December 31, 2023 compared to the year ended December 31, 2022, driven primarily by increases in the number of
patients on therapy.

Royalty, contract and other revenue

Royalty and contract revenue in 2023 was primarily generated from various collaboration agreements, including one with Horizon Therapeutics plc (subsequently acquired by Amgen Inc.) for which
$6.0 million was recognized in connection with the target produce profile milestone achieved.

Cost of goods sold

Cost of goods sold increased by $6.0 million or 26.6% for the year ended December 31, 2023 compared to the year ended December 31, 2022. The increase was mainly attributable to higher product
sales, partially offset by the product mix and a one-time contract credit in the first quarter of 2023.

Research and development expenses

69

 
Table of Contents

Research and development expenses increased by $1.4 million or 6.6% for the year ended December 31, 2023 compared to the year ended December 31, 2022, driven by the expenses related to the
Phase 2 study for XP-8121.

Selling, general and administrative expenses

Selling, general and administrative expenses increased by $8.4 million or 6.1% for the year ended December 31, 2023 compared to the year ended December 31, 2022, due to higher personnel costs
and rent expenses related to the new lease which commenced in April 2023.

Amortization of intangible assets

For the years ended December 31, 2023 and December 31, 2022, amortization of intangible assets were both $10.8 million.

Other income (expense)

For the year ended December 31, 2023, interest expense increased $12.5 million or 88.7% compared to the year ended December 31, 2022. The increase was primarily due to a higher principal
amount and increased interest rates related to third party debt arrangements.

Other expense in the years ended December 31, 2023 and December 31, 2022 included losses of $2.8 million and $1.2 million, respectively, on extinguishment of debt related to the third party debt
arrangements.

For the year ended December 31, 2023, change in fair value of contingent value rights was a gain of $5.2 million compared to a loss of $3.2 million for the year ended December 31, 2022. The gain
in 2023 were primarily due to changes in revenue assumptions based on recent trends adjusted for management’s estimates of future sales.

Liquidity and Capital Resources

Our  primary  uses  of  cash  are  to  fund  costs  related  to  the  manufacturing,  marketing  and  selling  of  products,  the  research  and  development  of  our  product  candidates,  general  and  administrative
expenses and working capital requirements. Historically, we have funded our operations primarily through private placements of convertible preferred stock, public equity offerings of common stock,
and issuance of debt.

On January 2, 2022, we entered into a securities purchase agreement in connection with the private placement of our common stock with Armistice for aggregate gross proceeds of approximately
$30.0 million and completed the transaction on January 3, 2022. In January 2022, we filed a shelf registration statement on Form S-3 with the SEC, which was declared effective on February 7, 2022,
and which covers the offering, issuance and sale by us of up to an aggregate of $250.0 million of our common stock, preferred stock, debt securities, warrants and/or units.

In March 2022, we, Xeris Pharma and certain subsidiary guarantors, entered into a Credit Agreement and Guaranty (the "Hayfin Loan Agreement") with the lenders from time to time parties thereto
(the "Lenders") and Hayfin Services LLP, as administrative agent for the Lenders, pursuant to which we and our subsidiaries party thereto granted a first priority security interest on substantially all of
our assets, including intellectual property, subject to certain exceptions. The Hayfin Loan Agreement provided for the Lenders to extend $100.0 million in term loans to us on the closing date and up
to an additional $50.0 million in delayed draw term loan(s) during the one year period immediately following the closing date (collectively, the "Loans"). On December 28, 2022, we borrowed the full
amount of such $50.0 million delayed draw term loan under the Hayfin Loan Agreement. In conjunction with the execution of the Hayfin Loan Agreement, the Oxford Loan Agreement balance of
$43.5  million  was  repaid  in  full  and  fees  of  $2.1  million  in  connection  with  the  loan  repayment  were  paid.  In  addition  to  utilizing  the  proceeds  to  repay  the  obligations  under  the  Oxford  Loan
Agreement in full, the proceeds were otherwise used for general corporate purposes. After repayment, the Loans may not be re-borrowed.

In September 2023, we completed the exchange of $32.0 million in aggregate principal amount of the 2025 Convertible Notes for $33.6 million in aggregate principal amount of the 2028 Convertible
Notes. As of December 31, 2023, the outstanding balance of the 2025 Convertible Notes was $15.2 million and the outstanding balance of the 2028 Convertible Notes was $33.6 million.

Capital Resources and Funding Requirements

We have incurred operating losses since inception, and we have an accumulated deficit of $617.0 million at December 31, 2023. Based on our current operating plans and existing working capital at
December  31,  2023,  we  believe  that  our  cash  resources  are  sufficient  to  sustain  operations  and  capital  expenditure  requirements  for  at  least  the  next  12  months.  We  expect  to  incur  substantial
additional expenditures in the near term to support the marketing and selling of Gvoke, Recorlev and Keveyis as well as our ongoing research and development activities. We expect to continue to
incur net losses for at least the next 12 months. Our ability to fund marketing and selling of Gvoke, Recorlev and Keveyis, as well as our product development and clinical operations, including

70

Table of Contents

completion of future clinical trials, will depend on the amount and timing of cash received from product revenue and potential future financings. Our future capital requirements will depend on many
factors, including, but not limited to:









our degree of success in commercializing Gvoke, Recorlev and Keveyis;
the costs of commercialization activities, including product marketing, sales and distribution;

the costs, timing and outcomes of clinical trials and regulatory reviews associated with our product candidates;
the effect on our product development activities of actions taken by the FDA or other regulatory authorities;
the number and types of future products we develop and commercialize;
the emergence of competing technologies and products and other adverse market developments; and
the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims.

As we continue the marketing and selling of Gvoke, Recorlev and Keveyis, we may not generate a sufficient amount of product revenue to fund our cash requirements. Accordingly, we may need to
obtain additional financing in the future which may include public or private debt and/or equity financings. As detailed in "Note 1 – Liquidity and capital resources" of Item 8 in this Form 10-K, there
can be no assurance that such funding may be available to us on acceptable terms, or at all, or that we will be able to successfully market and sell Gvoke, Recorlev and Keveyis.

Net cash used in operating activities was $47.0 million for the year ended December 31, 2023, compared to $102.9 million for the year ended December 31, 2022. The decrease in net cash used in
operating activities was primarily driven by reduced working capital usage, partially offset by changes to the fair value of contingent value rights. For a discussion regarding product revenue, net and
increases in spending, refer to "Results of Operations" included in this "Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations" of Part II.

Investing activities

Net cash used in investing activities was $6.0 million for the year ended December 31, 2023, compared to net cash provided by investing activities of $34.5 million for the year ended December 31,
2022. Cash used in investing activities in 2023 was primarily due to the purchase of short-term investments. In 2022, we used the majority of investments that matured to fund operations instead of

Net cash used in financing activities was $1.6 million for the year ended December 31, 2023, compared to net cash provided by financing activities of $127.5 million for the year ended December 31,
2022. The cash provided by financing activities in 2022 was primarily due to the net proceeds of $30.0 million from the January 2022 private placement of our common stock with an affiliate of
Armistice, proceeds net of debt issuance costs of $141.3 million from the Hayfin Loan Agreement, partially offset by the payoff of the outstanding principal under the Oxford Loan Agreement of
$43.5 million in March 2022.

CRITICAL ACCOUNTING POLICIES AND USE OF ESTIMATES AND ASSUMPTIONS

Our  management’s  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  on  our  financial  statements  have  been  prepared  in  accordance  with  generally  accepted  accounting
principles ("GAAP") in the United States. The preparation of these financial statements requires us to make estimates that affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and
judgments, including, among others, those related to revenue recognition and contingent considerations. We base our estimates on historical experience and on various other factors we believe to be
appropriate under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

We  believe  that  the  accounting  policies  discussed  below  are  critical  to  understanding  our  historical  and  future  performance,  as  these  policies  relate  to  the  more  significant  areas  involving
management’s judgments and estimates. Our significant accounting policies are more fully described in "Note 2 - Summary of Significant Accounting Policies" of Item 8 in this Form 10-K.

Revenue recognition

We apply the guidance in ASC 606, Revenue Recognition, to all contracts with customers within the scope of the standard.

We sell product primarily to wholesalers or a specialty pharmacy that subsequently resell to retail pharmacies or patients. We enter into arrangements with payors, group purchasing organizations, and
healthcare providers that provide for government-mandated or privately-negotiated rebates, chargebacks and discounts related to our products. We currently sell Gvoke, Recorlev and Keveyis in the
United States only and Ogulo (the brand name in the European Union and United Kingdom for the Company's ready-to-use liquid glucagon product) in the United Kingdom.

Revenue is recognized when our customer (e.g., a wholesaler or specialty pharmacy) obtains control of promised goods or services, which is when our obligations under the terms of the contract with
the customer are satisfied, based on the consideration we expect to receive in exchange for those goods or services.

Revenues are recorded at the net product sales price, which includes estimated allowances for patient copay assistance programs, prompt payment discounts, payor rebates, chargebacks, service fees,
and product returns, all of which are recorded at the time of sale to the pharmaceutical wholesaler or other customer. The Company applies significant judgments and estimates in determining some of
these allowances. If actual results differ from its estimates, adjustments are made to these allowances in the period in which the actual results or updates to estimates become known.

    Patient Copay Assistance Program

We offer savings programs to commercially insured patients under which the cost of a prescription to a patient is discounted. We reimburse pharmacies for this discount through a third-party
vendor. We record an accrual to reduce gross sales for the estimated copay on units sold to wholesalers and other customers. The estimate is based on estimated percentages of products that
will be prescribed to qualified patients, expected patient utilization of the discount program, average assistance paid based on reporting from the third-party vendor as well as industry data
and estimated levels of inventory in the distribution channel. Accrued copay fees are recorded as a reduction of product revenue and included in accrued trade discounts and rebates on the
consolidated balance sheets.

Commercial Rebates

We  contract  with  certain  private  payor  organizations,  primarily  insurance  companies  and  pharmacy  benefit  managers,  to  provide  rebates  with  respect  to  utilization  of  the  products  and
contracted formulary status. We accrue estimated rebates based on actual average rebate amounts and estimated percent of product that will be prescribed to qualified patients and record the
rebate as a reduction of product revenue. Accrued commercial rebates are included in accrued trade discounts and rebates on the consolidated balance sheets.

    Government Rebates

We participate in certain federal and state government rebate programs such as the Medicaid Drug Rebate Program, TRICARE Retail Refunds Program, and Medicare Part D Program. We
accrue  estimated  rebates  and  discounts  based  on  actual  average  rebate  amounts  and  estimated  percent  of  product  that  will  be  prescribed  to  qualified  patients  and  record  the  rebates  as  a
reduction of product revenue. Accrued government rebates are included in accrued trade discounts and rebates on the consolidated balance sheets.

Chargebacks

We arrange with certain commercial and government entities allowing them to buy products directly from wholesalers at specific prices. These entities purchase products through wholesalers
at  the  discounted  price  and  the  wholesalers  charge  the  difference  between  their  list  price  and  the  discounted  price  back  to  us.  We  accrue  estimated  chargebacks  based  on  estimated
percentages of products sold to these entities, contract prices, and estimated levels of inventory in the distribution channel and records the chargebacks as a reduction of product revenue.
Accrued chargebacks are recorded as an allowance against trade receivables on the consolidated balance sheets.

    Product Returns

For some products, our customers generally have the right to return product during the period beginning six months prior to the product expiration date and up to one year after the product
expiration date. We use actual return data to estimate the provision for returns. In a reporting period, we may decide to constrain revenue for product returns based on information from
various sources, including channel inventory levels, inventory dating, prescription data, the expiration dates of product currently being shipped, price changes of competitive products and
introductions of generic products. While we believe that our returns reserve is sufficient to avoid a significant reversal of revenue in future periods, if it were to increase or decrease the rate
by 1%, it would have a $1.5 million impact on revenue in the year ended December 31, 2023. We record estimated product returns in accrued returns reserve on the consolidated balance
sheets and as a reduction of product revenue.

Contingent considerations

The fair value of the CVRs was calculated by using a discounted cash flow method for the Keveyis patent milestone and an option pricing method for the Recorlev and Keveyis sales milestones. In
the case of Keveyis milestones, we applied a scenario-based method

72

Table of Contents

and  weighted  them  based  on  the  possible  achievement  of  the  milestone.  This  fair  value  measurement  is  based  on  significant  inputs  not  observable  in  the  market  and  thus  represents  a  Level  3
measurement as defined in ASC 820, Fair Value Measurement. The key assumptions used include the discount rate and sales growth. A 1% change of the discount rate will change the CVR value by
approximately $0.02 million or 0.1%. A 10% change of estimated net revenue will change the CVR value by approximately $1.7 million or 8%. The estimated value of the CVR consideration is
based upon available information and certain assumptions which our management believes are reasonable under the circumstances. The ultimate payout under the CVRs may differ materially from
the assumptions used in determining the fair value of the CVR consideration. This value is then remeasured for future expected payout as well as the increase in fair value due to the time value of
money. These gains or losses, if any, are recognized in the consolidated statements of operations and comprehensive loss.

NEW ACCOUNTING STANDARDS

Refer to "Note 2 - Basis of presentation and summary of significant accounting policies and estimates," in Item 8 of this Form 10-K for a description of recent accounting pronouncements applicable
to our financial statements.

JOBS ACT ACCOUNTING ELECTION

We  were  an  “emerging  growth  company”,  as  defined  in  the  Jumpstart  Our  Business  Startups  Act  of  2012  (the  “JOBS  Act”).  However,  we  became  an  accelerated  filer  and  thus  ceased  to  be  an
emerging growth company on December 31, 2023. As a result, we were required to adopt new or revised accounting standards as required by public companies, including those standards which we
had previously deferred pursuant to the JOBS Act. Additionally, we are no longer able to take advantage of the reduced regulatory and reporting requirements of emerging growth companies.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to certain market risks arising from transactions in the normal course of business, principally risk associated with interest rate and foreign currency exchange rate fluctuations.

Interest Rate Risk

Cash, Cash Equivalents restricted cash and Investments—We  are  exposed  to  the  risk  of  interest  rate  fluctuations  on  the  interest  income  earned  on  our  cash,  cash  equivalents,  restricted  cash  and
investments. A hypothetical one-percentage point increase or decrease in interest rates applicable to our cash, cash equivalents, restricted cash and investments outstanding at December 31, 2023
would increase or decrease interest income by approximately $0.7 million on an annual basis.

Long-term Debt—Our interest rate risk relates primarily to the United States dollar SOFR-indexed borrowings. Based on our outstanding borrowings pursuant to the Hayfin Loan Agreement, interest
is incurred at a floating per annum rate in an amount equal to the sum of (i) 9.0% (or 8.0% per annum if the replacement rate in effect is the Wall Street Journal Prime Rate) plus (ii) the greater of (x)
(1) CME Group Benchmark Administration Limited (CBA) Term SOFR (or the replacement rate, if applicable) if CBA Term SOFR is greater than 1.00% plus 0.26161% or (2) 1.00% if CME Term
SOFR is less than 1.00% and (y) one percent (1.00%) per annum (or 2.0% per annum if the replacement rate in effect is the Wall Street Journal Prime Rate). Interest on the 2025 Convertible Notes is
assessed at a fixed rate of 5.0% annually and interest on the 2028 Convertible Notes is assessed at a fixed rate of 8.0% annually and therefore do not subject us to interest rate risk.

Foreign Exchange Risk

We  contract  with  research  organizations  outside  the  United  States  at  times.  We  may  be  subject  to  fluctuations  in  foreign  currency  exchange  rates  in  connection  with  certain  of  these  agreements.
Transactions denominated in currencies other than the functional currency are recorded based on exchange rates at the time such transactions arise. Net foreign currency gains and losses did not have
a material effect on our results of operations for the year ended December 31, 2023.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Xeris is responsible for establishing and maintaining adequate internal control over financial reporting. Management has designed our internal control over financial reporting to
provide reasonable assurance that our published financial statements are fairly presented, in all material respects, in conformity with generally accepted accounting principles.

Management is required by paragraph (c) of Rule 13a-15 of the Securities Exchange Act of 1934, as amended, to assess the effectiveness of our internal control over financial reporting as of each
year end. In making this assessment, management used the Internal Control - Integrated Framework (2013) by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Management conducted the required assessment of the effectiveness of our internal control over financial reporting as of December 31, 2023. Based upon this assessment, management believes that
our internal control over financial reporting is effective as of December 31, 2023.

Ernst & Young LLP, the independent registered public accounting firm that audited our financial statements included in this Form 10-K, has also audited our internal control over financial reporting.
Their attestation report follows this report of management.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Xeris Biopharma Holdings, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheet of Xeris Biopharma Holdings, Inc. (the Company) as of December 31, 2023, the related consolidated statements of operations and
comprehensive loss, stockholders' equity and cash flows for the year then ended, 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 at December 31, 2023, and the results of its operations and its cash flows for the year then ended, in conformity with U.S.
generally accepted accounting principles.
We also have 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, 2023, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework)
and our report dated March 6, 2024 expressed an unqualified opinion thereon.
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 a public
accounting  firm  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 Matter
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 the critical audit matter does not alter in any way our opinion on the consolidated 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 account or disclosures to which it relates.

Description of the Matter

How We Addressed the
Matter in Our Audit

Valuation of Contingent Value Rights Liability

As described in Notes 2 and 13 to the consolidated financial statements, the Company recognized a liability for contingent value rights (“CVRs”) in connection with its
acquisition of Strongbridge in 2021. The CVR liability was recorded at fair value on the acquisition date and is revalued at the end of each subsequent reporting period,
with changes in fair value recognized in the consolidated statement of operations and comprehensive loss in the period of change. At December 31, 2023, the fair value
of the CVR liability was $20.5 million.

Auditing the Company’s accounting for the CVR liability was complex and required significant auditor judgment due to the complexity of the valuation methodology
and the significant estimation uncertainty in determining the fair value of the CVR liability. The significant estimation uncertainty was primarily due to the sensitivity of
the fair value to the underlying revenue growth rate assumption. This significant assumption is forward-looking and could be affected by future market conditions.

We  obtained  an  understanding,  evaluated  the  design,  and  tested  the  operating  effectiveness  of  controls  over  the  Company’s  accounting  for  the  CVR  liability.  For
example, we tested controls over the valuation of the CVR liability, including management’s review of the significant assumption described above.

To  test  the  fair  value  of  the  CVR  liability,  we  performed  audit  procedures  that  included,  among  others,  inspecting  the  terms  of  the  CVR  agreement,  evaluating  the
valuation methodologies used with assistance of our valuation specialist, and testing the key contractual inputs and significant assumption discussed above. We evaluated
the revenue growth assumption by comparing it to observable historical product level sales trends, and third-party analyses of the products. We also performed sensitivity
analyses over the revenue growth assumption to evaluate the changes in the fair value that would result from changes in that assumption.

Opinion on Internal Control Over Financial Reporting

Report of Independent Registered Public Accounting Firm

We have audited Xeris Biopharma Holdings, Inc.’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control—Integrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Xeris Biopharma Holdings, Inc. (the Company) maintained, in all
material respects, effective internal control over financial reporting as of December 31, 2023, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December
31, 2023, the related consolidated statements of operations and comprehensive loss, stockholders' equity and cash flows for the year then ended, and the related notes and our report dated March 6,
2024 expressed an unqualified opinion thereon.

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  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  a  public  accounting  firm  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 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.

Opinion on the Consolidated Financial Statements

Report of Independent Registered Public Accounting Firm

We have audited the accompanying consolidated balance sheet of Xeris Biopharma Holdings, Inc. and subsidiaries (the Company) as of December 31, 2022, the related consolidated statements of
operations and comprehensive loss, stockholders’ equity, and cash flows for each of the years in the two‑year period ended December 31, 2022, and the related notes (collectively, the consolidated
financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022, and the results of its
operations and its cash flows for each of the years in the two‑year period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  these  consolidated  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 consolidated
financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  consolidated
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

Note 1. Organization and nature of the business

Nature of business

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

Xeris Biopharma Holdings, Inc. ("Xeris Biopharma" or the "Company") is a growth-oriented biopharmaceutical company committed to improving patients' lives by developing and commercializing
clinically  meaningful  products  across  a  range  of  therapies.  The  Company  currently  has  three  commercially  available  products:  Gvoke,  a  ready-to-use,  liquid-stable  glucagon  for  the  treatment  of
severe hypoglycemia; Keveyis, the first therapy approved in the United States to treat hyperkalemic, hypokalemic, and related variants of Primary Periodic Paralysis ("PPP"); and Recorlev, a cortisol
synthesis inhibitor for the treatment of endogenous hypercortisolemia in adult patients with Cushing’s syndrome approved by the Food and Drug Administration ("FDA") in December 2021. The
Company also has a pipeline of development programs to bring new products forward using its proprietary formulation science, XeriSol and XeriJect.

As used herein, the "Company" or "Xeris" refers to Xeris Pharmaceuticals, Inc. ("Xeris Pharma") when referring to periods prior to the acquisition of Strongbridge Biopharma plc ("Strongbridge") on
October 5, 2021 and to Xeris Biopharma when referring to periods on or subsequent to October 5, 2021.

Throughout this document, unless otherwise noted, references to Gvoke include Gvoke PFS, Gvoke HypoPen, Gvoke Kit and Ogluo (glucagon).

The Company is subject to a number of risks similar to other specialty pharmaceutical companies, including, but not limited to, successful commercialization and market acceptance of available
products  and  any  future  products,  if  and  when  approved,  successful  development  of  the  product  candidates,  the  development  of  new  technological  innovations  by  competitors,  and  protection  of
intellectual property.

Liquidity and capital resources

The Company has incurred operating losses since inception and has an accumulated deficit of $617.0 million as of December 31, 2023. The Company expects to continue to incur net losses for at
least the next 12 months beyond the issuance date of these consolidated financial statements. Based on the Company’s current operating plans, existing working capital at December 31, 2023, the
Company believes that its cash resources are sufficient to sustain operations and capital expenditure requirements for at least the next 12 months from the issuance date of these consolidated financial
statements.

If needed, the Company may elect to finance its operations through equity or debt financing along with revenues. There can be no assurance that such funding may be available to the Company on
acceptable terms, or at all, or that the Company will be able to successfully market and sell Gvoke, Recorlev and Keveyis. Market volatility resulting from geopolitical instability resulting from the
ongoing  military  conflicts  between  Russia  and  Ukraine  and  Israel  and  Hamas,  rising  interest  rates,  inflationary  pressures,  the  tightening  of  lending  standards,  a  potential  shutdown  of  the  U.S.
government, any further deterioration in the macroeconomic economy or financial services industry resulting from actual or potential bank failures, or other factors could also adversely impact the
Company's  ability  to  access  capital  as  and  when  needed.  The  issuance  of  equity  securities  may  result  in  dilution  to  stockholders.  If  the  Company  raises  additional  funds  through  the  issuance  of
additional  debt,  which  may  have  rights,  preferences  and  privileges  senior  to  those  of  the  Company's  common  stockholders,  the  terms  of  the  debt  could  impose  significant  restrictions  on  the
Company's operations. The failure to raise funds as and when needed could have a negative impact on the Company's financial condition and ability to pursue its business strategies. If additional
funding is not secured when required, the Company may need to delay or curtail its operations until such funding is received, which would have a material adverse impact on the business prospects
and results of operations.

Note 2. Basis of presentation and summary of significant accounting policies and estimates

Basis of presentation

The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The accompanying consolidated financial
statements reflect all adjustments, consisting only of normal recurring adjustments, considered necessary for a fair presentation of the Company’s financial position, results of operations and cash
flows for the periods presented. The results of operations for such periods are not necessarily indicative of the results that may be expected for any future period.

Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification ("ASC") and Accounting Standards Update ("ASU") issued by the
Financial Accounting Standards Board ("FASB").

Basis of consolidation

These consolidated financial statements include the financial statements of Xeris Biopharma Holdings, Inc. and subsidiaries. All intercompany transactions have been eliminated.

Use of estimates

84

Table of Contents

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets,  liabilities,  revenues  and
expenses included in the financial statements and accompanying notes. Actual results could differ from those estimates.

Revenue recognition

The Company applies the guidance in ASC 606, Revenue Recognition, to all contracts with customers within the scope of the standard.

The  Company  sells  product  primarily  to  wholesalers  or  a  specialty  pharmacy  that  subsequently  resell  to  retail  pharmacies  or  patients.  The  Company  enters  into  arrangements  with  payors,  group
purchasing  organizations,  and  healthcare  providers  that  provide  for  government-mandated  or  privately-negotiated  rebates,  chargebacks  and  discounts  related  to  the  Company’s  products.  The
Company currently sells Gvoke, Recorlev and Keveyis in the United States only.

Revenue is recognized when the Company's customer (e.g., a wholesaler or specialty pharmacy) obtains control of promised goods or services, which is when the Company's obligations under the
terms of the contract with the customer are satisfied, based on the consideration the Company expects to receive in exchange for those goods or services.

Revenues are recorded at the net product sales price, which includes estimated allowances for patient copay assistance programs, prompt payment discounts, payor rebates, chargebacks, service fees,
and product returns, all of which are recorded at the time of sale to the pharmaceutical wholesaler or other customer. The Company applies significant judgments and estimates in determining some of
these allowances. If actual results differ from its estimates, adjustments are made to these allowances in the period in which the actual results or updates to estimates become known.

Patient Copay Assistance Program

The  Company  offers  savings  programs  to  commercially  insured  patients  under  which  the  cost  of  a  prescription  to  a  patient  is  discounted.  The  Company  reimburses  pharmacies  for  this
discount through a third-party vendor. The Company records an accrual to reduce gross sales for the estimated copay on units sold to wholesalers and other customers. The estimate is based
on estimated percentages of products that will be prescribed to qualified patients, expected patient utilization of the discount program, average assistance paid based on reporting from the
third-party vendor as well as industry data and estimated levels of inventory in the distribution channel. Accrued copay fees are recorded as a reduction of product revenue and included in
accrued trade discounts and rebates on the consolidated balance sheets.

Commercial Rebates

The Company contracts with certain private payor organizations, primarily insurance companies and pharmacy benefit managers, to provide rebates with respect to utilization of the products
and contracted formulary status. The Company accrues estimated rebates based on actual average rebate amounts and estimated percent of product that will be prescribed to qualified patients
and records the rebate as a reduction of product revenue. Accrued commercial rebates are included in accrued trade discounts and rebates on the consolidated balance sheets.

    Government Rebates

The Company participates in certain federal and state government rebate programs such as the Medicaid Drug Rebate Program, TRICARE Retail Refunds Program, and Medicare Part D
Program. The Company accrues estimated rebates and discounts based on actual average rebate amounts and estimated percent of product that will be prescribed to qualified patients and
records the rebates as a reduction of product revenue. Accrued government rebates are included in accrued trade discounts and rebates on the consolidated balance sheets.

Chargebacks

The Company arranges with certain commercial and government entities allowing them to buy products directly from wholesalers at specific prices. These entities purchase products through
wholesalers  at  the  discounted  price  and  the  wholesalers  charge  the  difference  between  their  list  price  and  the  discounted  price  back  to  the  Company.  The  Company  accrues  estimated
chargebacks based on estimated percentages of products sold to these entities, contract prices, and estimated levels of inventory in the distribution channel and records the chargebacks as a
reduction of product revenue. Accrued chargebacks are recorded as an allowance against trade receivables on the consolidated balance sheets.

    Product Returns

For some products, the Company's customers may have the right to return product during the period beginning six months prior to the product expiration date and up to one year after the
product expiration date. The Company uses actual return data to estimate the provision for returns. In a reporting period, the Company may decide to constrain revenue for product returns
based on information from various sources, including channel inventory levels, inventory dating, prescription data, the expiration dates of product currently being shipped, price changes of
competitive products and introductions of generic

85

Table of Contents

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

products. While the Company believes that the returns reserve is sufficient to avoid a significant reversal of revenue in future periods, if it were to increase or decrease the rate by 1%, it
would have a $1.5 million impact on revenue in the year ended December 31, 2023. The Company records estimated product returns in accrued returns reserve on the consolidated balance
sheets and as a reduction of product revenue.

Prompt Payment Discounts

As an incentive for prompt payment, the Company offers a discount to most customers. The Company expects that all eligible customers will comply with the contractual terms to earn the
discount, and, therefore, the Company accrues the discount on all eligible sales. The Company records the discount as an allowance against trade accounts receivable on the consolidated
balance sheets and as a reduction of product revenue.

Service Fees

The  Company  records  service  fees  paid  to  the  wholesaler  and  specialty  pharmacy  customers  for  distribution  and  inventory  management  services  as  a  reduction  to  product  revenue.  The
Company accrues estimated service fees based on contractually determined amounts. Accrued service fees are included in accrued trade discounts and rebates on the consolidated balance
sheets.

Concentration of credit risk

For the years ended December 31, 2023, 2022 and 2021, four customers accounted for 97%, 96%, and 95% of the Company’s gross product revenue, respectively. At each of December 31, 2023 and
December 31, 2022, the same four customers accounted for 99% of the trade accounts receivable, net.

Cost of goods sold

Cost of goods sold includes primarily product costs, which include all costs directly related to the purchase of raw materials, charges from contract manufacturing organizations, and manufacturing
overhead  costs,  including  shipping  and  distribution  charges.  Cost  of  goods  sold  also  includes  losses  on  excess,  slow-moving  or  obsolete  inventory  and  inventory  purchase  commitments,  if  any.
Manufacturing costs for Gvoke and Recorlev incurred prior to approval and initial commercialization were expensed as research and development expenses.

The Company does not incur material cost of goods sold related to royalty, contract and other revenue.

Research and development expenses

Research and development expenses are expensed as incurred. Research and development expenses include salaries, stock compensation and other personnel-related costs, consulting fees, fees paid
for contract research and development services including those for preclinical and clinical trials, laboratory equipment and facilities costs, and other external costs. In addition, manufacturing costs of
products prior to approval and initial commercialization are expensed as research and development costs.

Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are deferred and capitalized. The capitalized amounts are expensed
as the related goods are received, the services are performed, or the arrangement is terminated.

Stock-based compensation expense

The Company accounts for stock-based compensation awards in accordance with ASC 718, Compensation-Stock Compensation ("ASC 718"). ASC 718 requires all stock-based payments, including
stock options, restricted stock units and employee stock purchases, to be recognized in the statements of operations based on their grant date fair values. The Company estimates the grant date fair
value of each option award using the Black-Scholes option-pricing model. The use of the Black-Scholes option-pricing model requires management to make assumptions with respect to the expected
term  of  the  option,  the  expected  volatility  of  the  common  stock  consistent  with  the  expected  life  of  the  option,  the  risk-free  interest  rate  and  the  expected  dividend  yield  of  the  common  stock.
Restricted stock units are valued based on the fair market value of the Company’s common stock on the date they were granted. The Company recognizes stock-based compensation expense equal to
the grant date fair value of stock options, restricted stock units and employee stock purchases on a straight-line basis over the requisite service period. The Company accounts for forfeitures as they
are incurred.

Income taxes

Income taxes are recorded in accordance with ASC 740, Income Taxes ("ASC 740"), which provides for deferred taxes using an asset and liability approach. The Company recognizes deferred tax
assets and liabilities for the expected future tax consequences of events

86

Table of Contents

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

that have been included in the financial statements or tax returns. The Company determines the deferred tax assets and liabilities based on differences between financial reporting and tax bases of
assets and liabilities, which are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are provided if, based upon the
weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740. When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the
extent that the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position
as well as consideration of the available facts and circumstances. The Company's policy is to include interest and penalties related to uncertain tax positions, if any, within the provision for taxes in
the statements of operations and comprehensive loss. For the years ended December 31, 2023, 2022 and 2021, the Company did not accrue any interest or penalties on uncertain tax positions.

Cash and cash equivalents

The Company considers all demand deposits with financial institutions and highly liquid investments with an original maturity of three months or less when purchased as cash equivalents.

Restricted Cash

Restricted cash includes amounts required to be held as a security deposit in the form of letters of credit for the Company to secure leases and state licenses.

Investments

The Company classifies investments in debt securities as available-for-sale investments. Investments classified as short-term on the balance sheets have original maturities of greater than 90 days but
less than one year.

Inventory

Inventory is stated at the lower of cost or net realizable value, using the first-in, first-out convention. Inventory consists of raw materials, work in process and finished goods. The Company has
entered into manufacturing and supply agreements for the manufacture or purchase of raw materials and production supplies. The Company’s inventory includes the direct purchase cost of materials
and supplies, charges from contract manufacturing organizations and manufacturing overhead costs. The Company reviews inventory to assess if there is obsolete or excess inventory and records a
charge to cost of goods sold if and when applicable.

Property and equipment

Property and equipment are carried at cost less accumulated depreciation. Depreciation is calculated utilizing the straight-line method over the estimated useful lives of the respective assets:

Lab equipment
Computer equipment
Leasehold improvements
Software
Furniture and fixtures
Office equipment

Impairment of long-lived assets

5 years
3 years
Lesser of useful life or lease term
3-5 years
5 years
5 years

The Company periodically evaluates long-lived assets such as property and equipment, intangible assets subject to amortization, and right-of-use assets on operating leases for potential impairment in
accordance with ASC 360, Property, Plant and Equipment. Potential impairment is assessed when there is evidence that events or changes in circumstances indicate that the carrying amount of an
asset may not be recovered. Recoverability of these assets is assessed based on undiscounted expected future cash flows from the assets, considering a number of factors, including past operating
results, budgets and economic projections, market trends and product development cycles. If impairments are identified, assets are written down to their estimated fair value.

The Company recognized no impairment charges for the years ended December 31, 2023, 2022 and 2021.

Goodwill

The Company tests goodwill for impairment on an annual basis or whenever events occur that may indicate possible impairment. Goodwill is recorded as the difference, if any, between the aggregate
consideration paid for an acquisition and the fair value of the net

87

Table of Contents

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

tangible and identified intangible assets acquired under a business combination. Goodwill is reviewed for impairment at a reporting unit level annually in the fourth quarter, or more frequently if
events  or  circumstances  indicate  that  the  goodwill  might  be  impaired.  The  Company  first  assesses  qualitative  factors  to  determine  whether  it  is  necessary  to  perform  the  quantitative  goodwill
impairment test. If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of the net assets is less than their carrying
amount, then the quantitative goodwill impairment test is unnecessary.

If, based on the qualitative assessment, it is determined that it is more likely than not that the fair value of the net assets is less than their carrying amount, then the Company proceeds to perform the
quantitative goodwill impairment test. In connection with the annual impairment test conducted in the fourth quarter of 2023, 2022 and 2021, the Company performed a qualitative assessment in
connection with the annual goodwill impairment evaluation and determined that it was more likely than not that the fair value of the net assets exceeded their carrying value.

Intangible assets

Acquired definite life intangible assets are amortized using the straight-line method over their respective estimated useful lives. The Company evaluates the potential impairment of intangible assets if
events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate.

The identified intangible assets are reviewed for impairment whenever events or changes in business circumstances arise that may indicate that the carrying amount of its intangible assets may not be
recoverable. These events and changes can include significant current period operating losses or negative cash flows associated with the use of an intangible asset, or group of assets, combined with a
history of such factors, significant changes in the manner of use of the assets, and current expectations that it is more likely than not that an intangible asset will be sold or otherwise disposed of
significantly before the end of its previously estimated useful life. When impairment indicators are present, the Company compares undiscounted future cash flows to the asset group’s carrying value
to determine if the asset group is recoverable. If the carrying values are in excess of undiscounted expected future cash flows, the Company measures any impairment by comparing the fair value of
the asset or asset group to its carrying value.

No impairment expense was recorded for identified intangible assets during the year ended December 31, 2023, 2022 and 2021.

For further discussion of identified intangible assets, see "Note 8 – Intangible assets".

Debt issuance costs

Debt issuance costs incurred in connection with financing arrangements are amortized to interest expense over the life of the respective financing arrangement using the effective interest method.
Debt issuance costs, net of related amortization, reduce the carrying value of the related debt.

Contingent considerations

The fair value of the Contingent Value Rights ("CVRs") is calculated by using a discounted cash flow method for the Keveyis patent milestone and an option pricing method for the Recorlev and
Keveyis sales milestones. In the case of Keveyis milestones, the Company applies a scenario-based method and weights them based on the possible achievement of the milestone. This fair value
measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement as defined in ASC 820, Fair Value Measurement.  The  key  assumptions  used
include the discount rate and sales growth. The estimated value of the CVR consideration is based upon available information and certain assumptions which the Company's management believes are
reasonable under the circumstances. The ultimate payout under the CVRs may differ materially from the assumptions used in determining the fair value of the CVR consideration. This value is then
remeasured for future expected payout as well as the increase in fair value due to the time value of money. These gains or losses, if any, are recognized in the consolidated statements of operations
and comprehensive loss.

Lease Accounting

Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the present value of the Company’s obligation to make lease
payments arising from the lease over the lease term at the commencement date of the lease. As most of the Company’s leases do not provide an implicit rate, the Company estimated the incremental
borrowing rate based on the information available at the date of adoption in determining the present value of lease payments and used the implicit rate when readily determinable. The Company
determined incremental borrowing rates through market sources for secured borrowings including relevant industry rates. The Company excludes variable payments from lease ROU assets and lease
liabilities to the extent not considered in-substance fixed, and instead, expenses variable payments as incurred. The Company’s operating leases expire at various times in 2031 and 2037, some of
which include options to extend leases. The exercise of lease renewal options is at the Company’s sole discretion and the Company’s lease ROU assets and liabilities reflect only the options the
Company is reasonably certain that it will exercise. We do not have leases with residual value guarantees or similar covenants.

Warrant liability

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

Warrants  required  to  be  settled  in  cash  are  accounted  for  as  liabilities  in  accordance  with  ASC  480,  Distinguishing  Liabilities  from  Equity.  The  fair  value  of  these  warrants  are  remeasured  each
reporting  period  using  the  Black-Scholes  option-pricing  model  which  considers  the  expected  term  of  the  warrants  as  well  as  the  risk-free  interest  rate  and  expected  volatility  of  the  Company's
common stock. The liability is recorded in other current liabilities on the consolidated balance sheets. Generally, changes in the fair value of the warrant liabilities are recorded in the consolidated
statements of operations and comprehensive loss.

Fair value of financial instruments

Fair value is the price that could be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value determination in accordance with applicable
accounting guidance requires that a number of significant judgments be made. Additionally, fair value is used on a non-recurring basis to evaluate assets for impairment or as required for disclosure
purposes  by  applicable  accounting  guidance  on  disclosures  about  fair  value  of  financial  instruments.  Depending  on  the  nature  of  the  assets  and  liabilities,  various  valuation  techniques  and
assumptions  are  used  when  estimating  fair  value.  The  carrying  amounts  of  certain  of  the  Company’s  financial  instruments,  including  cash,  cash  equivalents,  restricted  cash,  accounts  receivable,
prepaid expenses and other current assets, and accounts payable, are shown at cost, which approximates fair value due to the short-term nature of these instruments. The debt outstanding under the
Amended and Restated Loan and Security Agreement approximates fair value due to the variable interest rate on the debt. Items measured at fair value on a recurring basis include the Company’s
investments, warrants and CVRs. The fair value of the convertible senior notes is determined from using current interest rates based on credit ratings and the remaining term of maturity.

Segment reporting

Operating segments are identified as components of an enterprise for which separate discrete financial information is available and utilized by the chief operating decision maker in making decisions
regarding resource allocation and assessing performance. The Company operates in one segment.

New accounting pronouncements

Adopted accounting standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard requires entities to estimate
an expected lifetime credit loss on financial assets ranging from short-term trade accounts receivable to long-term financings and report credit losses using an expected losses model rather than the
incurred  losses  model  that  was  previously  used  and  establishes  additional  disclosures  related  to  credit  risks.  For  available-for-sale  debt  securities  with  unrealized  losses,  the  standard  requires
allowances  to  be  recorded  instead  of  reducing  the  amortized  cost  of  the  investment.  This  standard  limits  the  amount  of  credit  losses  to  be  recognized  for  available-for-sale  debt  securities  to  the
amount  by  which  carrying  value  exceeds  fair  value  and  requires  the  reversal  of  previously  recognized  credit  losses  if  the  fair  value  increases.  The  Company  adopted  this  standard  beginning  on
January 1, 2023, and it did not have a material impact on the financial statements.

Pending accounting standards

In  December  2023,  the  FASB  issued  ASU  2023-07,  Segment  Reporting  (Topic  280):  Improvements  to  Segment  Reporting  Disclosures.  This  standard  requires  an  entity  to  provide  more  detailed
information about its reportable segment expenses that are included within management’s measurement of profit and loss and will require certain annual disclosures to be provided on an interim
basis. The amendments in this ASU are effective for the Company in 2025 for annual reporting and in 2026 for interim reporting, with early adoption permitted beginning in 2024, and is required to
be applied using the full retrospective method of transition. The Company is evaluating the timing and effects of adoption of this ASU on the Company’s segment disclosures.

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-
40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.  This  standard  eliminates  certain  accounting  models  to  simplify  the  accounting  for  convertible  instruments,
expands the disclosure requirements related to the terms and features of convertible instruments, and amends the guidance for the derivatives scope exception for contracts settled in an entity’s own
equity. This standard enhances the consistency of earnings-per-share ("EPS") calculations by requiring that an entity use the if-converted method and that the effect of potential share settlement be
included in diluted EPS calculations and disclosures. This standard is effective for the Company for fiscal years beginning after December 15, 2023. The Company is currently evaluating the impact
the adoption of this new standard will have on the financial statements and disclosures.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This standard provides optional
expedients for application of GAAP, if certain criteria are met, to contracts and other transactions that reference London Inter-bank Offered Rate ("LIBOR") or other reference rates that are expected
to

89

Table of Contents

Notes to Consolidated Financial Statements

be discontinued because of reference rate reform. This standard is effective for all entities as of March 12, 2020 through December 31, 2022. On December 21, 2022, the FASB issued ASU 2022-06,
Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extends the period of time entities can utilize the reference rate reform relief guidance under ASU 2020-04 from
December 31, 2022 to December 31, 2024. The Company does not currently expect the adoption of this new standard to have a material impact on the financial statements.

The Company classifies investments in debt securities as available-for-sale. Debt securities are comprised of liquid investments that are highly rated securities and, as of December 31, 2023, consist
of U.S. government securities, all with remaining maturities of less than one year. Debt securities as of December 31, 2023 had an average remaining maturity of 0.1 years. The debt securities are
reported at fair value with unrealized gains or losses recorded in accumulated other comprehensive income (loss) in the consolidated balance sheets. The cost of short-term investments is adjusted for
amortization of premiums or accretion of discounts to maturity, and such amortization or accretion, as well as interest income, are included in interest and other income in the consolidated statements
of operations and comprehensive loss. Refer to "Note 13 - Fair Value Measurements," for information related to the fair value measurements and valuation methods utilized.

For available-for-sale securities in an unrealized loss position, the Company first assesses whether they are intended to be sold, or if it is more likely than not that the Company will be required to sell,
the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through
earnings. For available-for-sale securities that do not meet the above criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this
assessment, the Company considers the severity of the impairment, any changes in interest rates, market conditions, changes to the underlying credit ratings and forecasted recovery, among other
factors. The credit-related portion of unrealized losses, and any subsequent improvements, are recorded in interest income through an allowance account. Any impairment that has not been recorded
through an allowance for credit losses is included in other comprehensive loss on the statements of operations and comprehensive loss. No credit loss allowance was recorded in the years ended
December 31, 2023, 2022 and 2021.

Note 7. Goodwill

Goodwill is evaluated for potential impairment annually, as of the beginning of the fourth quarter and whenever events or changes in circumstances indicate the carrying amount of goodwill may not
be recoverable. The process of evaluating goodwill for potential impairment is subjective and requires significant estimates, assumptions and judgments.

As of December 31, 2023, the Company assessed qualitative and quantitative factors and determined that it was not more-likely-than-not that the fair value of the one reporting unit was less than the
carrying value as of the testing date. As a result of the assessment, no goodwill impairment charge was recorded during the fiscal year ended December 31, 2023, 2022 and 2021.

After the completion of the acquisition of Strongbridge on October 5, 2021, the Company undertook a restructuring plan to streamline the organization and realize operating expense synergies. The
Company incurred total restructuring costs of approximately $11.1 million, which primarily related to employee termination costs. These costs were fully recognized and recorded by 2022 in selling,
general and administrative expenses in the consolidated statements of operations and comprehensive loss. The plan was fully paid out in the fourth quarter of 2023.

In June 2020, Xeris Pharma completed a public offering of $86.3 million aggregate principal amount of Xeris Pharma's 5.00% Convertible Senior Notes due 2025 (the "2025 Convertible Notes"),
including $11.3 million pursuant to the underwriters' option to purchase additional notes, which was exercised in full in July 2020. Since January 15, 2021, the 2025 Convertible Notes bear cash
interest at the rate of 5.00% per annum, payable semi-annually in arrears on January 15 and July 15 of each year.

Notes to Consolidated Financial Statements

Xeris Pharma incurred debt issuance costs of $5.1 million in connection with the issuance of the 2025 Convertible Notes. At any time before the close of business on the second scheduled trading day
immediately before the maturity date, holders of 2025 Convertible Notes may convert their 2025 Convertible Notes at their option into shares of the Company’s common stock, together, if applicable,
with cash in lieu of any fractional share, at a conversion rate of 326.7974 shares of the Company's common stock per $1,000 principal amount of 2025 Convertible Notes. In the second half of 2020,
$39.1 million in principal amount of 2025 Convertible Notes were converted into 13,171,791 shares of Xeris Pharma’s common stock.

On September 29, 2023, the Company completed the exchange of $32.0 million in aggregate principal amount of the 2025 Convertible Notes for $33.6 million in aggregate principal amount of new
8.00% Convertible Notes due 2028 (the "2028 Convertible Notes" and together with the 2025 Convertible Notes, the "Convertible Notes"). As of December 31, 2023, the outstanding balance of the
2025 Convertible Notes was $15.2 million and the outstanding balance of the 2028 Convertible Notes was $33.6 million.

The Company evaluated the exchange agreement for debt modification and concluded that the debt qualified for debt extinguishment. Upon extinguishment, the Company recognized the new 2028
Convertible Notes at their fair value of $34.1 million, and derecognized the carrying value of $32.0 million for the 2025 Convertible Notes and $0.7 million of unamortized initial debt issuance costs
resulting in a net loss on debt extinguishment of $2.8 million.

The 2025 Convertible Notes are governed by the terms of a base indenture for senior debt securities dated June 30, 2020 (the "2025 Base Indenture"), as supplemented by the first supplemental
indenture dated June 30, 2020 (the "First Supplemental Indenture"), and the second supplemental indenture dated October 5, 2021 (the "Second Supplemental Indenture" and together with the 2025
Base  Indenture  and  First  Supplemental  Indenture,  the  "2025  Indenture"),  among  the  Company,  Xeris  Pharma  and  U.S.  Bank  Trust  Company,  National  Association  (f/k/a  U.S.  Bank  National
Association), as trustee (the "Trustee"). The 2028 Convertible Notes are governed by the terms of an indenture for senior debt securities dated September 29, 2023 (the "2028 Indenture" and together
with the 2025 Indenture, the "Indentures") among the Company, Xeris Pharma and the Trustee. The 2025 Convertible Notes and the 2028 Convertible Notes will mature on July 15, 2025 and July 15,
2028, respectively, unless earlier converted or redeemed or repurchased.

The Convertible Notes are senior, unsecured obligations and are equal in right of payment with Xeris Pharma's existing and future senior, unsecured indebtedness, senior in right of payment to its
future  indebtedness,  if  any,  that  is  expressly  subordinated  to  the  Convertible  Notes,  and  effectively  subordinated  to  its  existing  and  future  secured  indebtedness  to  the  extent  of  the  value  of  the
collateral securing that indebtedness. The Convertible Notes are structurally subordinated to all existing and future indebtedness and other liabilities, including trade payables, and (to the extent Xeris
Pharma is not a holder thereof) preferred equity, if any, of the Company’s other direct and indirect subsidiaries.

As a result of the transactions associated with the acquisition of Strongbridge, and pursuant to the Second Supplemental Indenture, the 2025 Convertible Notes are no longer convertible into shares of
common stock of Xeris Pharma. Instead, subject to the terms and conditions of the 2025 Indenture, the 2025 Convertible Notes will be exchangeable into cash and shares of common stock of the
Company  in  proportion  to  the  transaction  consideration  payable  pursuant  to  the  transaction  agreement  for  the  acquisition  of  Strongbridge,  and  the  "Reference  Property"  provisions  in  the  2025
Indenture.

The fair value of the Convertible Notes is determined from using current interest rates based on credit ratings and the remaining term of maturity. As of December 31, 2023, the fair value of the
Convertible Notes was approximately $55.1 million. The fair value of the convertible debt was estimated using inputs for volatility, the Company’s stock price, time to maturity, the risk-free rate and
the Company’s credit spread, some of which are considered Level 3 inputs in the fair value hierarchy disclosed in "Note 13 - Fair value measurement."

Loan Agreement

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

In September 2019, Xeris Pharma entered into an Amended and Restated Loan and Security Agreement (the "Oxford Loan Agreement") with Oxford Finance LLC ("Oxford"), as the collateral agent
and a lender, and Silicon Valley Bank, as a lender ("SVB," and together with Oxford, the "Prior Lenders"). The Oxford Loan Agreement provided for the Prior Lenders to extend up to $85.0 million
in term loans to Xeris Pharma in three tranches, of which $60.0 million was drawn down in September 2019.

In June 2020, Xeris Pharma paid a portion of the term loan equal to the sum of $20.0 million, plus all accrued and unpaid interest. In November 2020, an additional $3.5 million was drawn from the
term loan.

In March 2022, the Company, Xeris Pharma and certain subsidiary guarantors of the Company entered into a Credit Agreement and Guaranty (as amended, modified or amended and restated from
time to time, the "Hayfin Loan Agreement") with the lenders from time to time parties thereto (the "Lenders") and Hayfin Services LLP, as administrative agent for the Lenders (in such capacity,
together with its successors and assigns, the "Agent"), pursuant to which the Company and its subsidiaries party thereto granted a first priority security interest on substantially all of their assets,
including intellectual property, subject to certain exceptions. The Hayfin Loan Agreement provided for the Lenders to extend $100.0 million in term loans to the Company on the closing date and up
to  an  additional  $50.0  million  in  delayed  draw  term  loans  during  the  one  year  period  immediately  following  the  closing  date  (collectively,  the  "Loans").  On  December  28,  2022,  the  Company
borrowed  the  full  amount  of  such  $50.0  million  delayed  draw  term  loan  under  the  Hayfin  Loan  Agreement.  In  conjunction  with  the  execution  of  the  Hayfin  Loan  Agreement,  the  Oxford  Loan
Agreement remaining balance of $43.5 million and fees of $2.1 million in connection with the loan repayment were paid. In addition to utilizing the proceeds to repay the obligations under the
Oxford Loan Agreement in full, the proceeds were otherwise used for general corporate purposes.

The Loans incur interest at a floating per annum rate in an amount equal to the sum of (i) 9.0% (or 8.0% per annum if the replacement rate in effect is the Wall Street Journal Prime Rate) plus (ii) the
greater of (x) (1) CME Group Benchmark Administration Limited (CBA) Term SOFR (or the replacement rate, if applicable) if CBA Term SOFR is greater than 1.00% plus 0.26161% or (2) 1.00% if
CME Term SOFR is less than 1.00% and (y) one percent (1.00%) per annum (or 2.0% per annum if the replacement rate in effect is the Wall Street Journal Prime Rate). The Company has incurred
total  debt  issuance  costs  of  approximately  $3.6  million  related  to  the  Hayfin  Loan  Agreement,  which  are  being  amortized  to  interest  expense  over  the  life  of  the  loan  using  the  effective  interest
method. The remaining balance of unamortized debt issuance costs have been reflected as a direct reduction to the loan balance. The effective interest rate, including the amortization of debt discount
and debt issuance costs, amounts to approximately 11.8%. The debt outstanding under the Hayfin Loan Agreement approximates fair value due to the variable interest rate on the debt.

The Loans will mature on March 8, 2027; provided, however, the Loans will mature on January 15, 2025 if the 2025 Convertible Notes are outstanding as of such date and either (i) the maturity date
thereof  has  not  been  extended  to  a  date  on  or  after  September  4,  2027  or  (ii)  the  Company  has  not  received  net  cash  proceeds  from  one  or  more  permitted  equity  raises  or  permitted  raises  of
convertible debt which, together with no more than $15.6 million of cash on hand, is sufficient to redeem and discharge the 2025 Convertible Notes in full.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements are
classified and disclosed in one of the following categories:

Level 1: Measured using unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2: Measured using quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs, other than
quoted prices in active markets, that are observable either directly or indirectly.

Level 3: Measured based on prices or valuation models that require inputs that are both significant to the fair value measurement and less observable from objective sources (i.e., supported by
little or no market activity).

Fair value measurements are classified based on the lowest level of input that is significant to the measurement. The Company’s assessment of the significance of a particular input to the fair value
measurement requires judgment, which may affect the valuation of the assets and liabilities and their placement within the fair value hierarchy levels. The determination of the fair values stated below
considers the market for the financial assets and liabilities, the associated credit risk and other factors as required. The Company

considers active markets as those in which transactions for the assets or liabilities occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

The following tables present the Company’s fair value hierarchy for those assets and liabilities measured at fair value as of December 31, 2023 and December 31, 2022 (in thousands):

As  part  of  the  2021  acquisition  of  Strongbridge,  the  Company  issued  contingent  value  rights  ("CVRs") representing  additional  contingent  consideration  of  up  to  $1.00  for  each  CVR  upon  the
achievement of the following:

• Keveyis Milestone: $0.25 per CVR, upon the earlier of the first listing of any patent in the FDA's Orange Book for Keveyis by the end of 2023 or the first achievement of at least $40 million

in net revenue of Keveyis in 2023;

•

•

2023 Recorlev Milestone: $0.25 per CVR, upon the first achievement of at least $40 million in net revenue of Recorlev in 2023; and

2024 Recorlev Milestone: $0.50 per CVR, upon the first achievement of at least $80 million in net revenue of Recorlev in 2024.

97

Table of Contents

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

There are approximately 74.1 million CVRs. Up to 8.3 million CVRs may be issued to holders of Strongbridge rollover options and assumed warrants upon the exercise thereof. CVRs are settleable
in cash, common stock, or a combination of cash and common stock, at the Company's sole election.

Contingent consideration obligations are recorded at their estimated fair values and these obligations are revalued at each reporting period until the related contingencies are resolved. The CVRs are
adjusted to fair value using the methods described above at the end of each reporting period. Significant changes which increase or decrease the probabilities of achieving the related milestones or
shorten or lengthen the time required to achieve such events would result in corresponding increases or decreases in the fair values of these obligations.

The Company has determined that the CVR liabilities' fair values are Level 3 items within the fair value hierarchy. The following table presents the change in the CVR liabilities (in thousands):

The Company’s 375.0 million authorized shares of stock are divided into 350.0 million shares of common stock, par value $0.0001 per share, and 25.0 million shares of undesignated preferred stock,
par value $0.0001 per share. At December 31, 2023, none of the 25.0 million shares of preferred stock were outstanding, and the Company has no present plans to issue any shares of preferred stock.
The  Company’s  board  of  directors  has  the  authority,  without  action  by  the  Company’s  stockholders,  to  designate  and  issue  the  preferred  stock  in  one  or  more  series  and  to  designate  the  rights,
preferences, limitations and privileges of each series of preferred stock, which may be greater than the rights of the Company’s common stock.

The Company has not paid any cash dividends on the common stock during the periods presented.

On January 3, 2022, the Company entered into a securities purchase agreement in connection with a private placement with an affiliate of Armistice Capital, LLC ("Armistice") for aggregate gross
proceeds of approximately $30.0 million. In accordance with the purchase agreement, the Company issued to Armistice an aggregate of (i) 10,238,908 shares of the Company’s common stock, par

Note 15. Stock compensation plan

In 2011, the Company adopted the 2011 Stock Option Issuance Plan (the "2011 Plan") and subsequently amended it to authorize the Board of Directors to issue up to 4,714,982 incentive stock option
and non-qualified stock option awards.

The 2018 Stock Option and Incentive Plan (the "2018 Plan") was adopted by the Board of Directors in April 2018 and approved by the Company's stockholders in June 2018 to award up to 1,822,000
shares of common stock. The 2018 Plan replaced the 2011 Plan as the Board of Directors decided not to make additional awards under the 2011 Plan following the closing of the IPO, which occurred
in  June  2018.  The  2018  Plan  allows  the  compensation  committee  to  make  equity-based  and  cash-based  incentive  awards  to  the  Company's  officers,  employees,  directors  and  other  key  persons
(including consultants). No grants of stock options or other awards may be made under the 2018 Plan after the tenth anniversary of the effective date.

As of December 31, 2023, there were 3,240,766 shares of common stock available for future issuance under the 2018 Plan.

The 2018 Employee Stock Purchase Plan (the "ESPP") was adopted by the Board of Directors in April 2018 and approved by the Company's stockholders in June 2018 to issue up to 193,000 shares
of common stock to participating employees. Through the ESPP, eligible employees may authorize payroll deductions of up to 15% of their compensation to purchase up to the number of shares of
common stock determined by dividing $25,000 by the closing market price of Xeris common stock on the offering date. The purchase price per share at each purchase date is equal to 85% of the
lower of (i) the closing market price per share of Xeris common stock on the employee’s offering date or (ii) the closing market price per share of Xeris common stock on the purchase date. Each
offering period has a six-month duration and purchase interval. As of December 31, 2023, there were 76 shares available for issuance under the ESPP.

The Equity Inducement Plan (the "Inducement Plan") was adopted by the Board of Directors in February 2019. The Inducement Plan allows the Company to make stock option or restricted stock unit
awards to prospective employees of the Company as an inducement to such individuals to commence employment with the Company. The Company uses this Inducement Plan to help it attract and
retain prospective employees who are necessary to support the commercialization of products and the expansion of the Company generally. As of December 31, 2023, there were 365,949 shares of
common stock available for future issuance under the Inducement Plan.

Assumed Plans

On  the  acquisition  date  of  Strongbridge,  the  Company  assumed  all  then-outstanding  stock  options  and  shares  available  and  reserved  for  issuance  under  some  legacy  equity  incentive  plans  of
Strongbridge, including the Strongbridge 2015 equity compensation plan and Strongbridge 2017 inducement plan (collectively, the "Assumed Plans"). Shares reserved under the Assumed Plans will
be available for future grants. The Company also assumed all then-outstanding stock options from the rest of the legacy equity incentive plans of Strongbridge without assuming the shares available
and reserved for issuance under these plans. The number of shares subject to stock options outstanding under all Strongbridge legacy equity incentive plans are included in the tables below. As of
December 31, 2023, there were 1,908,897 shares reserved for future grants under the Assumed Plans.

Stock options

Stock options are granted with an exercise price equal to the market price of the Company’s stock at the date of grant. Stock option awards typically vest over either two, three or four years after the
grant date and expire seven to ten years from the grant date.

The fair value of each option is estimated on the date of grant using a Black-Scholes option valuation model that uses the assumptions noted in the following table. The expected term of options
represents the period of time that options granted are expected to be outstanding. The risk-free interest rate for periods during the contractual life of the option is based on the United States Treasury
yield curve in effect at the time of grant. The expected stock price volatility assumption is based on the historical volatilities of a peer group of publicly traded companies as well as the historical
volatility of the Company's common stock, since the Company began trading subsequent to the IPO in June 2018, over the period corresponding to the expected life as of the grant date. The expected
dividend yield is based on the expected annual dividend as a percentage of the market value of the Company’s ordinary shares as of the grant date.

At December 31, 2023, there was a total of $0.6 million of unrecognized stock-based compensation expense related to stock options that is expected to be recognized over a weighted average period
of 0.9 years.

Restricted Stock Units

The Company grants Restricted Stock Units ("RSUs") to employees. RSUs that are granted vest over either three or four years in equal annual installments beginning on the one-year anniversary of
the date of grant, provided that the employee is employed by the Company on such vesting date. If and when the RSUs vest, the Company will issue one share of common stock for each whole RSU
that has vested, subject to satisfaction of the employee’s tax withholding obligations. Upon vesting and settlement of RSUs or exercise of stock options, at the election of the grantee, the Company
does not collect withholding taxes in cash from employees. Instead, the Company withholds upon settlement as RSUs vest, or as stock options are exercised, the portion of those shares with a fair
market value equal to the amount of the minimum statutory withholding taxes due. The withheld shares are accounted for as repurchases of common stock. Stock-based compensation expense related
to RSUs is recognized on a straight-line basis over the employee’s requisite service period.

A summary of outstanding RSU awards and the activity for the years ended December 31, 2023 and December 31, 2022 was as follows:

The Company sponsors an employee retirement plan qualifying under Section 401(k) of the Internal Revenue Code for all eligible employees in the United States. Employees become eligible to
contribute to the plan upon meeting certain age requirements and 30 days of service. Commencing in 2019, the Company began discretionary matching employee contributions up to certain limits.
For the years ended December 31, 2023, 2022 and 2021, the Company made $2.4 million, $1.7 million and $0.7 million of matching contributions to the plan, respectively.

Deferred Compensation Plan

The Compensation Committee of the Board of Directors adopted a deferred compensation plan ("Deferred Compensation Plan") in April 2020. The Deferred Compensation Plan allows a select group
of executive management and non-employee directors to defer payment of certain of their cash compensation. Participants in the Deferred Compensation Plan who are employees may defer all or a
portion of their annual base salaries and all or a portion of their annual cash performance-based compensation. Participants who are non-employee directors may defer all or a portion of their annual
cash retainers. The participants’ elective deferrals are 100% vested immediately and accrue interest at a rate of two percent per annum. The Deferred Compensation Plan is unfunded and unsecured.
As of December 31, 2021, the total deferred compensation liability under the Deferred Compensation Plan was approximately $1.6 million recorded in other current liabilities in the consolidated
balance sheets and was fully paid off in January 2022.

Note 17. Leases

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

The Company has non-cancellable operating leases for office and laboratory space, which expire at various times in 2031 and 2037. The non-cancellable lease agreements provide for monthly lease
payments, which increase during the term of each lease agreement.

On  September  29,  2022,  Xeris  Pharma  amended  and  restated  its  existing  lease  with  Fulton  Ogden  Venture,  LLC  to  expand  the  leased  premises  to  accommodate  the  Company’s  relocation  of  its
headquarters to such premises. The term of the space existing prior to the amendment and restatement commenced on January 1, 2021 and the lease for the combined expanded space commenced on
April 1, 2023. The term of the amended and restated lease will expire on March 31, 2036, unless extended or earlier terminated pursuant to the terms of the lease.

All  of  the  Company's  leases  are  classified  as  operating  leases,  which  are  included  as  operating  lease  right-of-use  assets  and  current  and  non-current  operating  lease  liabilities  in  the  consolidated
balance sheets. The Company’s operating lease costs are included in operating expenses in the accompanying consolidated statements of operations and comprehensive loss. The Company's lease
agreements do not contain any material residual value guarantees or material restrictive covenants.

A  majority  of  the  Company's  lease  agreements  include  fixed  rental  payments.  Certain  lease  agreements  include  fixed  rental  payments  that  are  adjusted  periodically  by  a  fixed  rate.  The  fixed
payments, including the effects of changes in the fixed rate or amount, and renewal options reasonably certain to be exercised, are included in the measurement of the related lease liability. The
exercise of lease renewal options is at the Company's sole discretion. The depreciable life of assets and leasehold improvements are limited by the expected lease term, which includes renewal options
reasonably certain to be exercised. The majority of the Company's real estate leases require that the Company pay maintenance, real estate taxes and insurance in addition to rent. These payments are
generally variable and based on actual costs incurred by the lessor. Therefore, these amounts are not included in the consideration of the contract when determining the right-of-use asset and lease
liability but are reflected as variable lease expenses.

As  the  interest  rate  implicit  in  the  lease  is  not  readily  determinable,  the  Company  uses  the  incremental  borrowing  rate  as  the  discount  rate.  The  Company  considers  observable  inputs  as  of  the
effective  date  of  the  ASC  842  adoption  including  the  credit  rating,  existing  borrowings  and  other  relevant  borrowing  rates,  such  as  risk-free  rates  like  the  United  States  Treasury  rate,  and  then
adjusting as necessary for the appropriate lease term. The incremental borrowing rate is reassessed if there is a change to the lease term or if a modification occurs and it is not accounted for as a
separate contract. As of December 31, 2023, the Company’s operating leases had a weighted-average remaining lease term of 11.6 years and a weighted-average discount rate of 11.9%.

The Company has a supply agreement with Taro Pharmaceuticals North America, Inc. ("Taro") to produce Keveyis. In 2023, the Company amended the agreement to extend the initial term until
March 2027. As part of the agreement, as amended, the Company has agreed to certain annual minimum marketing spend requirements and minimum purchase order quantities for each year, which in
the case of the minimum purchase order quantities, is based on the previous year's purchases.

Leases

As of December 31, 2023, the Company had unused letters of credit of $4.2 million, which were issued primarily to secure leases. These letters of credit are collateralized by $4.2 million of restricted
cash, which is recorded in other assets in the consolidated balance sheets.

Litigation

From time to time, the Company may become involved in various legal actions arising in the ordinary course of business. As of December 31, 2023, management was not aware of any existing,
pending or threatened legal actions that would have a material impact on the financial position or results of operations of the Company.

Long Term Debt

In the event the 2025 Convertible Notes are still outstanding as of January 15, 2025 and the maturity date thereof has not been extended to a date on or after September 4, 2027, then unless the
Company  has  received  net  cash  proceeds  from  one  or  more  permitted  equity  raises  or  permitted  raises  of  convertible  debt  which,  together  with  no  more  than  $15.6  million  of  cash  on  hand,  is
sufficient to

redeem and discharge the 2025 Convertible Notes in full, the loans outstanding under the Hayfin Loan Agreement will mature on January 15, 2025.

Note 19. Net loss per common share

Basic and diluted net loss per common share are determined by dividing net loss applicable to common stockholders by the weighted average common shares outstanding during the period. For all
periods presented, the shares issuable upon conversion, exercise or vesting of Convertible Notes, warrants, stock option awards and RSUs have been excluded from the calculation because their
effects would be anti-dilutive. Therefore, the weighted average common shares outstanding used to calculate both basic and diluted net loss per common share are the same.

The following potentially dilutive securities were excluded from the computation of diluted weighted average common shares outstanding due to their anti-dilutive effect:

Shares to be issued upon conversion of Convertible Notes
Vested and unvested stock options
Restricted stock units
Warrants

 1
Total anti-dilutive securities excluded from EPS computation

Total anti-dilutive securities exclude CVRs which are settleable in cash, additional Xeris Biopharma shares, or a combination, at the election of the Company.

The benefit for income taxes for 2023 was attributable to the amortization of the deferred tax liability set up with the Acquisition.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of the assets and liabilities for financial reporting purposes and the amounts used for income
tax purposes. A valuation allowance is required to be established or maintained when, based on currently available information, it is more likely than not that all or a portion of a deferred tax asset
will not be realized. The guidance on accounting for income taxes provides important factors in determining whether a deferred tax asset will be realized, including whether there has been sufficient
taxable income in recent years and whether sufficient income can reasonably be expected in future years in order to utilize the deferred tax asset. For the years ended December 31, 2023, 2022 and
2021, the Company evaluated the need to maintain a valuation allowance for deferred tax assets based on the assessment of whether it is more likely than not that deferred tax benefits will be realized
through the generation of future taxable income. Appropriate consideration is given to all available evidence, both positive and negative, in assessing the need for a valuation allowance.

 Certain reclasses have been made to the 2022 balances in this table to conform to the 2023 presentations.

As of December 31, 2023, the Company had federal net operating loss carryforwards of $494.3 million and various state net operating loss carryforwards of $352.2 million. As of December 31, 2022,
the Company had federal net operating loss carryforwards of $501.4 million and various state net operating loss carryforwards of $345.3 million. Net operating loss carryforwards for the United
States federal income tax purposes that were generated prior to January 1, 2018 have a twenty-year carryforward life and will expire in 2037. Under the Tax Cuts and Jobs Act of 2017, federal net
operating losses incurred in 2018 and later years may be carried forward indefinitely, but the deductibility of such net operating losses is limited to 80% of the current year’s taxable income. The
United States state net operating loss carryforwards will start to expire in 2029 for the earliest net operating loss layers to the extent there is not sufficient state taxable income to utilize those net
operating loss carryforwards.

At December 31, 2023, the Company had $6.9 million and $3.7 million of federal and state income tax credits, respectively, to reduce future tax liabilities. At December 31, 2022, the Company had
$6.7 million and $3.1 million of federal and state income tax credits, respectively, to reduce future tax liabilities. The federal income tax credits consist primarily of orphan drug credits and research
and development credits. The United States state income tax credits consist primarily of California and Illinois research and development credits, as well as Illinois Economic Development for a
Growing Economy Tax Credit. Both the United States federal orphan drug credits and research and development credits have a twenty-year carryforward life. The United States federal orphan drug
credits and research and development credits will both begin to expire in 2038.

The  Company  is  required  to  recognize  the  financial  statement  effects  of  a  tax  position  when  it  is  more  likely  than  not,  based  on  the  technical  merits,  that  the  position  will  be  sustained  upon
examination. The Company accounts for the uncertainty in income taxes by utilizing a comprehensive model for the recognition, measurement, presentation and disclosure in financial statements of
any uncertain tax positions that have been taken, or are expected to be taken, on an income tax return. The changes in the Company's uncertain income tax positions for the years ended December 31,
2023, 2022 and 2021, excluding interest and penalties, consisted of the following (in thousands):

Beginning balance - uncertain tax positions

For the year ended December 31, 2023, the decrease in current year uncertain tax positions was attributable primarily to the United States federal orphan drug credits and research and development
credits and the decrease related to tax positions taken during the prior year was a result of return to provision adjustments. In the Company’s balance sheet, uncertain tax positions of $0.7 million were
offset against deferred tax assets. Tax years prior to 2019 generally are not subject to examination by the Internal Revenue Service or state or local taxing authorities.

The Company policy is to include interest and penalties related to uncertain tax penalties, if any, within the provision for taxes in the statements of operations. During the years ended December 31,
2023, 2022 and 2021, the Company incurred no interest and penalties related to income taxes.

XERIS BIOPHARMA HOLDINGS, INC.
Notes to Consolidated Financial Statements

On  March  5,  2024,  the  Company,  Xeris  Pharma  and  certain  subsidiary  guarantors  of  the  Company  entered  into  an  Amended  and  Restated  Credit  Agreement  and  Guaranty  (the  "Amended  and
Restated Credit Agreement") with the lenders from time to time parties thereto (the "New Lenders") and Hayfin Services LLP, as administrative agent for the New Lenders, pursuant to which the
Company and its subsidiaries party thereto granted a first priority security interest on substantially all of their assets, including intellectual property, subject to certain exceptions. The Amended and
Restated Credit Agreement provided for the New Lenders to extend $200.0 million in term loans to the Company on the closing date and up to an additional $15.2 million in additional term loans,
which additional term loans are available only to redeem the Company's existing 2025 Convertible Notes (collectively, the "2029 Loans"). The proceeds from the initial term loans will be used for
general corporate purposes. In conjunction with the execution of the Amended and Restated Credit Agreement, the aggregate principal balance of $150.0 million plus all accrued and unpaid interest
outstanding under the Hayfin Loan Agreement was continued under the Amended and Restated Credit Agreement.

The 2029 Loans incur interest at a floating per annum rate in an amount equal to 6.95% (the “Margin”) plus the greater of the forward-looking term rate based on SOFR for a three-month tenor and
2.00%. Upon the occurrence and during the continuance of certain events of default, the Margin will be increased by three percent (3.00%) per annum, and all interest shall be payable monthly.

The 2029 Loans will mature on March 5, 2029; provided, however, that the 2029 Loans will mature on (A) January 15, 2025 if the 2025 Convertible Notes are outstanding as of such date or (B)
January 15, 2028 if the 2028 Convertible Notes are outstanding as of such date and, in both cases, either (i) the maturity date of the applicable notes has not been extended to a date not earlier than
September  5,  2029  and  (ii)  the  Company  has  not  received  net  cash  proceeds  from  one  or  more  permitted  equity  raises  or  permitted  raises  of  convertible  debt  which,  together  with  no  more  than
$15.6 million of cash on hand, is sufficient to redeem and discharge the 2025 Convertible Notes or the 2028 Convertible, as applicable, in full.

COMPENSATION RECOVERY POLICY Adopted as of November 8, 2023 Xeris Biopharma Holdings, Inc., a Delaware corporation (the “Company”), has adopted a Compensation Recovery Policy (this “Policy”) as described below. 1. Overview The Policy sets forth the circumstances and procedures under which the Company shall recover Erroneously Awarded Compensation from current and former Executive Officers and other employees of the Company in accordance with rules issued by the United States Securities and Exchange Commission (the “SEC”) under the Securities Exchange Act of 1934 (the “Exchange Act”) and the Nasdaq Stock Market. Please refer to Section 3 below for definitions of capitalized terms used and not otherwise defined herein. 2. Compensation Recovery Requirement In the event the Company is required to prepare a Material Financial Restatement, the Company shall reasonably promptly recover all Erroneously Awarded Compensation with respect to such Material Financial Restatement, and each Covered Person shall be required to take all actions necessary to enable such recovery. 3. Definitions a. “Applicable Recovery Period” means with respect to a Material Financial Restatement, the three completed fiscal years immediately preceding the Restatement Date for such Material Financial Restatement. In addition, in the event the Company has changed its fiscal year: (i) any transition period of less than nine months occurring within or immediately following such three completed fiscal years shall also be part of such Applicable Recovery Period and (ii) any transition period of nine to 12 months will be deemed to be a completed fiscal year. b. “Applicable Rules” means any rules or regulations adopted by the Exchange pursuant to Rule 10D-1 under the Exchange Act and any applicable rules or regulations adopted by the SEC pursuant to Section 10D of the Exchange Act. c. “Board” means the Board of Directors of the
Company. d. “Committee” means the Compensation Committee of the Board or, in the absence of such committee, a majority of independent directors serving on the Board. e. A “Covered Person” means any Executive Officer and any other person designated by the Board or the Committee in writing as being subject to this Policy. A person’s status as a Covered Person with respect to Erroneously Awarded Compensation shall be determined as of the time of receipt of such Erroneously Awarded Compensation regardless of their current role or status with the Company (e.g., if a person began service as an Executive Officer after the beginning of an Applicable Recovery Period, Exhibit 97.1

2 that person would not be considered a Covered Person with respect to Erroneously Awarded Compensation received before the person began service as an Executive Officer, but would be considered a Covered Person with respect to Erroneously Awarded Compensation received after the person began service as an Executive Officer where such person served as an Executive Officer at any time during the performance period for such Erroneously Awarded Compensation). f. “Effective Date” means October 2, 2023. g. “Erroneously Awarded Compensation” means, with respect to a Material Financial Restatement, the amount of any Incentive-Based Compensation received by a Covered Person on or after the Effective Date during the Applicable Recovery Period that exceeds the amount that otherwise would have been received by the Covered Person had such compensation been determined based on the restated amounts in the Material Financial Restatement, computed without regard to any taxes paid. Calculation of Erroneously Awarded Compensation with respect to Incentive-Based Compensation based on stock price or total shareholder return, where the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in a Material Financial Restatement, shall be based on a reasonable estimate of the effect of the Material Financial Restatement on the stock price or total shareholder return upon which the Incentive-Based Compensation was received, and the Company shall maintain documentation of the determination of such reasonable estimate and provide such documentation to the Exchange in accordance with the Applicable Rules. h. “Exchange” means The Nasdaq Stock Market LLC. i. An “Executive Officer” means any person who served the Company in any of the following roles, received Incentive-Based Compensation after beginning service in any such role (regardless of whether such
Incentive-Based Compensation was received during or after such person’s service in such role) and served in such role at any time during the performance period for such Incentive-Based Compensation: the president, the principal financial officer, the principal accounting officer (or if there is no such accounting officer the controller), any vice president in charge of a principal business unit, division or function (such as sales, administration or finance), any other officer who performs a policy making function, or any other person who performs similar policy making functions for the issuer. Executive officers of parents or subsidiaries of the Company may be deemed executive officers of the Company if they perform such policy making functions for the Company. j. “Financial Reporting Measures” mean measures that are determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, any measures that are derived wholly or in part from such measures (including, for example, a non-GAAP financial measure), and stock price and total shareholder return.

 
3 k. “Incentive-Based Compensation” means any compensation provided, directly or indirectly, by the Company or any of its subsidiaries that is granted, earned, or vested based, in whole or in part, upon the attainment of a Financial Reporting Measure. Incentive-Based Compensation is deemed received, earned or vested when the Financial Reporting Measure is attained, not when the actual payment, grant or vesting occurs. l. A “Material Financial Restatement” means an accounting restatement of previously issued financial statements of the Company due to the material noncompliance of the Company with any financial reporting requirement under the securities laws, including any required accounting restatement to correct an error in previously-issued financial statements that is material to the previously-issued financial statements or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. m. “Restatement Date” means, with respect to a Material Financial Restatement, the earlier to occur of: (i) the date the Board or the Audit Committee concludes, or reasonably should have concluded, that the Company is required to prepare the Material Financial Restatement or (ii) the date a court, regulator or other legally authorized body directs the Company to prepare the Material Financial Restatement. 4. Exception to Compensation Recovery Requirement The Company may elect not to recover Erroneously Awarded Compensation pursuant to this Policy if the Committee determines that recovery would be impracticable, and one or more of the following conditions, together with any further requirements set forth in the Applicable Rules, are met: (i) the direct expense paid to a third party to assist in enforcing this Policy would exceed the amount to be recovered, and the Company has made a reasonable attempt to recover such Erroneously Awarded Compensation; or (ii) recovery would
likely cause an otherwise tax- qualified retirement plan to fail to be so qualified under applicable regulations. 5. Tax Considerations To the extent that, pursuant to this Policy, the Company is entitled to recover any Erroneously Awarded Compensation that is received by a Covered Person, the gross amount received (i.e., the amount the Covered Person received, or was entitled to receive, before any deductions for tax withholding or other payments) shall be returned by the Covered Person. 6. Method of Compensation Recovery The Committee shall determine, in its sole discretion, the method for recovering Erroneously Awarded Compensation hereunder, which may include, without limitation, any one or more of the following: a. requiring reimbursement of cash Incentive-Based Compensation previously paid;

 
4 b. seeking recovery of any gain realized on the vesting, exercise, settlement, sale, transfer or other disposition of any equity-based awards; c. cancelling or rescinding some or all outstanding vested or unvested equity-based awards; d. adjusting or withholding from unpaid compensation or other set-off; e. cancelling or setting-off against planned future grants of equity-based awards; and/or f. any other method permitted by applicable law or contract. Notwithstanding the foregoing, a Covered Person will be deemed to have satisfied such person’s obligation to return Erroneously Awarded Compensation to the Company if such Erroneously Awarded Compensation is returned in the exact same form in which it was received; provided that equity withheld to satisfy tax obligations will be deemed to have been received in cash in an amount equal to the tax withholding payment made. 7. Policy Interpretation This Policy shall be interpreted in a manner that is consistent with the Applicable Rules and any other applicable law and shall otherwise be interpreted (including in the determination of amounts recoverable) in the business judgment of the Committee. The Committee shall take into consideration any applicable interpretations and guidance of the SEC in interpreting this Policy, including, for example, in determining whether a financial restatement qualifies as a Material Financial Restatement hereunder. To the extent the Applicable Rules require recovery of Incentive-Based Compensation in additional circumstances besides those specified above, nothing in this Policy shall be deemed to limit or restrict the right or obligation of the Company to recover Incentive-Based Compensation to the fullest extent required by the Applicable Rules. This Policy shall be deemed to be automatically amended, as of the date the Applicable Rules become effective with respect to the Company, to the extent required for this Policy to comply with the Applicable Rules. 8. Policy
Administration This Policy shall be administered by the Committee. The Committee shall have such powers and authorities related to the administration of this Policy as are consistent with the governing documents of the Company and applicable law. The Committee shall have full power and authority to take, or direct the taking of, all actions and to make all determinations required or provided for under this Policy and shall have full power and authority to take, or direct the taking of, all such other actions and make all such other determinations not inconsistent with the specific terms and provisions of this Policy that the Committee deems to be necessary or appropriate to the administration of this Policy. The interpretation and construction by the Committee of any provision of this Policy and all determinations made by the Committee under this policy shall be final, binding and conclusive.

 
5 9. Compensation Recovery Repayments not Subject to Indemnification Notwithstanding anything to the contrary set forth in any agreement with, or the organizational documents of, the Company or any of its subsidiaries, Covered Persons are not entitled to indemnification for Erroneously Awarded Compensation recovered under this Policy and, to the extent any such agreement or organizational document purports to provide otherwise, Covered Persons hereby irrevocably agree to forego such indemnification. Adopted: November 8, 2023
