SUMMARY OF THE MATERIAL RISKS ASSOCIATED WITH OUR BUSINESS

Our business is subject to numerous material and other risks and uncertainties, including those described in Part I, Item 1A. “Risk Factors” in this Annual Report on Form 10-K. The principal risks
and uncertainties affecting our business include the following:

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

product candidate or future product candidates.

• Our business is significantly dependent on the successful development, regulatory approval and commercialization of FT218, our only product candidate.
• Our lead product candidate and future product candidates may not reach the commercial market for a number of reasons.
•

If we are not able to use the 505(b)(2) regulatory approval pathway for the regulatory approval of FT218 or if the U.S. Food and Drug Administration (“FDA”) requires additional clinical or
nonclinical  data  to  support  an  New  Drug  Application  under  Section  505(b)(2)  than  we  previously  anticipated,  it  will  likely  take  significantly  longer,  cost  significantly  more  and  be
significantly more complicated to gain FDA approval for FT218, and in any case may not be successful.

• We incurred a net loss in 2021 and we will likely incur a net loss in 2022, and if we are not able to regain profitability in the future, the value of our shares may fall.
• We may require additional financing, which may not be available on favorable terms or at all, and which may result in dilution of the equity interest of the holders of American Depositary

•

Shares (“ADSs”).
The distribution and sale of FT218, if approved, will be subject to significant regulatory restrictions, including the requirements of a Risk Evaluation and Mitigation Strategy (“REMS”) and
safety reporting requirements, and these regulatory requirements will subject us to risks and uncertainties, any of which could negatively impact sales of FT218, if approved.

• Disruptions at the FDA, the U.S. Drug Enforcement Administration 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.
FT218, if approved by the FDA, may not obtain desired regulatory exclusivities, including orphan drug exclusivity.

•
• We rely, and intend to continue to rely, on single source providers for the development, manufacture and supply of FT218, and if we experience problems with those suppliers, or they fail to

•
•

comply with applicable regulatory requirements or to supply sufficient quantities at acceptable quality levels or prices, or at all, our business would materially and adversely affected.
If we cannot adequately protect our intellectual property and proprietary information, we may be unable to effectively compete.
If we are unable to establish effective sales, marketing and distribution capabilities, or enter into agreements with third parties to market, sell and distribute FT218, if approved, our business,
results of operations, financial condition and prospects will be materially adversely affected.
COVID-19 may materially and adversely affect our business and our financial results.

•
• We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive, time consuming and unsuccessful.
•

The price of ADSs representing our ordinary shares has been volatile and may continue to be volatile.

PART I 

Item 1.        Business. 

General Overview

(Dollar amounts in thousands, except per-share amounts and as otherwise noted)

Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is a biopharmaceutical company. Our lead product candidate, FT218, is an investigational once-nightly,
extended-release formulation of sodium oxybate for the treatment of excessive daytime sleepiness (“EDS”) or cataplexy in adults with narcolepsy. We are primarily focused on the development and
potential  United  States  (“U.S.”)  Food  and  Drug  Administration  (“FDA”)  approval  of  FT218.  In  December  2020,  we  submitted  a  New  Drug  Application  (“NDA”)  to  the  FDA  for  FT218  to  treat
excessive daytime sleepiness or cataplexy in adults with narcolepsy. In February 2021, the NDA for FT218 was accepted by the FDA and was assigned a Prescription Drug User Fee Act (“PDUFA”)
target action date of October 15, 2021. On October 15, 2021, we announced that the FDA informed us that the review of our NDA for FT218 was ongoing beyond its previously assigned target action
date. As of the date of this Annual Report, the FDA’s review of our NDA for FT218 remains ongoing.

Outside of our lead product candidate, we continue to evaluate opportunities to expand our product portfolio. As of the date of this Annual Report, we do not have any approved or commercialized
products in our portfolio.

FT218

FT218  is  a  once-nightly  formulation  of  sodium  oxybate  that  uses  our  Micropump  controlled  release  drug-delivery  technology  for  the  treatment  of  EDS  or  cataplexy  in  adults  suffering  from
narcolepsy. Sodium oxybate is the sodium salt of gamma hydroxybutyrate, an endogenous compound and metabolite of the neurotransmitter gamma-aminobutyric acid. Immediate release sodium
oxybate is approved in the U.S. for the treatment of EDS or cataplexy in patients with narcolepsy and is approved in Europe for the treatment of cataplexy in patients with narcolepsy. Since 2002,
sodium oxybate has only been available as a formulation that must be taken twice nightly, first at bedtime, and then again 2.5 to 4 hours later.

On December 16, 2020, we announced the submission of our NDA to the FDA for FT218. On February 26, 2021, the FDA notified us of formal acceptance of the NDA and assigned a PDUFA target
action date of October 15, 2021. On October 15, 2021, we announced that the FDA informed us that the review of our NDA for FT218 was ongoing beyond its previously assigned target action date.
As of the date of this Annual Report, the FDA’s review of our NDA for FT218 remains ongoing.

We conducted a Phase 3 clinical trial of FT218, the REST-ON trial, which was a randomized, double-blind, placebo-controlled study that enrolled 212 patients who received at least one dose of
FT218 or placebo, and was conducted in clinical sites in the U.S., Canada, Western Europe and Australia. The last patient, last visit was completed at the end of the first quarter of 2020, and positive
top  line  data  from  the  REST-ON  trial  was  announced  on  April  27,  2020.  Patients  who  received  9  g  of  once-nightly  FT218,  the  highest  dose  administered  in  the  trial,  demonstrated  statistically
significant and clinically meaningful improvement compared to placebo across the three co-primary endpoints of the trial: maintenance of wakefulness test (“MWT”), clinical global impression-
improvement (“CGI-I”), and mean weekly cataplexy attacks. The lower doses assessed, 6 g and 7.5 g also demonstrated statistically significant and clinically meaningful improvement on all three co-
primary endpoints compared to placebo. We observed the 9 g dose of once-nightly FT218 to be generally well tolerated. Adverse reactions commonly associated with sodium oxybate were observed
in a small number of patients (nausea 1.3%, vomiting 5.2%, decreased appetite 2.6%, dizziness 5.2%, somnolence 3.9%, tremor 1.3% and enuresis 9%), and 3.9% of the patients who received 9 g of
FT218 discontinued the trial due to adverse reactions.

In  January  2018,  the  FDA  granted  FT218  orphan  drug  designation  for  the  treatment  of  narcolepsy,  which  makes  FT218  potentially  eligible  for  certain  development  and  commercial  incentives,
including  potential  U.S.  market  exclusivity  for  up  to  seven  years.  Additionally,  several  FT218-related  U.S.  patents  have  been  issued,  and  there  are  additional  patent  applications  currently  in
development and/or pending at the U.S. Patent and Trademark Office (“USPTO”), as well as foreign patent offices.

In July 2020, we announced that the first patient was dosed in our open-label extension (“OLE”)/switch study of FT218 as a potential treatment for EDS or cataplexy in patients with narcolepsy. The
OLE/switch study is examining the long-term safety and maintenance of efficacy of FT218 in patients with narcolepsy who participated in the REST-ON study, as well as dosing and preference data
for patients switching from twice-nightly sodium oxybate to once-nightly FT218, regardless of whether they participated in REST-ON. In May 2021, inclusion criteria were expanded to allow for
oxybate naïve patients to enter the study.

New secondary endpoints from the REST-ON trial were presented at the American Academy of Neurology, beginning April 17, 2021. The first poster described FT218 improvements in disturbed
nocturnal sleep (“DNS”), defined in REST-ON as the number of shifts from stages N1, N2, N3, and rapid eye movement (“REM”) sleep to wake and from stages N2, N3, and REM sleep to stage N1.
FT218 also decreased the number of nocturnal arousals as measured on polysomnography. Improvements in DNS were further supported by post-hoc analyses demonstrating increased time in deep
sleep (N3, also known as slow wave sleep), and less time in N1. A second poster described the statistically significant improvements in the Epworth Sleepiness Scale, both the quality of sleep and the
refreshing nature of sleep, and a decrease in sleep paralysis. These clinically relevant improvements were observed for all doses, beginning at week 3, for the lowest 6 g dose, compared to placebo.
FT218 did not demonstrate significant improvement for hypnagogic hallucinations compared to placebo.

Additional data supportive of the efficacy findings in REST-ON were presented at the 35th Annual Meeting of the Associated Professional Sleep Societies, a joint meeting of the American Academy
of Sleep Medicine and the Sleep Research Society, also known as SLEEP 2021, beginning June 10, 2021. New data included post-hoc analyses demonstrating endpoints improvements, regardless of
concomitant stimulant use, in both narcolepsy Type 1 or Type 2. Additionally, a post-hoc analysis showed that FT218 was associated with decreased body mass index compared to placebo, which
may be relevant as people with narcolepsy often have co-morbid obesity. In August 2021, the primary results from the REST-ON trial were published by Kushida et al. in the journal SLEEP. New
data was presented at the American College of Chest Physicians annual meeting, beginning October 17, 2021, including additional post-hoc analyses from the REST-ON trial, demonstrating a greater
proportion of patients receiving FT218 experienced reductions in weekly cataplexy attacks and improvement in mean sleep latency compared to placebo, as well as the results of a discrete choice
experiment, indicating that the overall driver of patient preference between sodium oxybate treatments is a once-nightly, versus twice-nightly, formulation.

We believe FT218 has the potential to demonstrate improved dosing compliance, safety and patient satisfaction over the current standards of care for EDS or cataplexy in patients with narcolepsy,
which are twice-nightly oxybate formulations.

Micropump Drug-Delivery Technology

Our Micropump drug-delivery technology allows for the controlled delivery of small molecule drugs taken orally, which has the potential to improve dosing compliance, reduce toxicity and improve
patient  compliance.  Beyond  FT218,  we  believe  there  could  be  other  product  development  opportunities  for  our  Micropump  drug-delivery  technology,  representing  either  life  cycle  opportunities,
whereby additional intellectual property can be added to a pharmaceutical product to extend the commercial viability of a currently marketed product, or innovative formulation opportunities for new
chemical entities.

Previously Approved FDA Products

On  June  30,  2020  (“Closing  Date”),  we  announced  the  sale  of  our  portfolio  of  sterile  injectable  drugs  used  in  the  hospital  setting  (the  “Hospital  Products”),  including  our  three  FDA-approved
commercial products, Akovaz, Bloxiverz and Vazculep, as well as Nouress, to Exela Sterile Medicines LLC (“Exela Buyer”).

Our Drug Delivery Technologies 

We  own  drug  delivery  technologies  that  address  formulation  challenges,  potentially  allowing  the  development  of  differentiated  drug  products  for  administration  in  various  forms  (e.g.,  capsules,
tablets, sachets or liquid suspensions for oral use; or injectables for subcutaneous administration) that could be applied to a broad range of drugs (novel, already-marketed, or off-patent).

A brief discussion of each of our drug delivery technologies is set forth below.

• Micropump.  Our  Micropump  technology  allows  for  the  development  of  modified  release  solid,  oral  dosage  formulations  of  drugs.  Micropump-carvedilol  and  Micropump-aspirin

formulations have been approved in the U.S. Further, Micropump technology is being employed in our investigational FT218 product.

•

LiquiTime. Our LiquiTime technology allows for development of modified release oral products in a liquid suspension formulation, which may make such formulations particularly well
suited  for  children  and/or  patients  having  issues  swallowing  tablets  or  capsules.  Although  we  own  this  technology,  we  are  currently  not  pursuing  any  commercial  pharmaceutical  drug
development opportunities using it.

-8-

 
• Medusa.  Our  Medusa  technology  allows  for  the  development  of  modified-release  injectable  dosage  formulations  of  drugs  (e.g.,  peptides,  polypeptides,  proteins,  and  small  molecules).

Although we own this technology, we are currently not pursuing any commercial pharmaceutical drug development opportunities using it.

Competition and Market Opportunities 

Competition 

Competition in the pharmaceutical and biotechnology industry is intense and is expected to increase. We compete with academic laboratories, research institutions, universities, joint ventures, and
other pharmaceutical and biotechnology companies, including other companies developing brand or generic specialty pharmaceutical products or drug delivery platforms. Some of these competitors
may also be our business partners. There can be no assurance that our competitors will not obtain patent protection or other intellectual property rights that would make it difficult or impossible for us
to  compete  with  their  products.  Furthermore,  major  technological  changes  can  happen  quickly  in  the  pharmaceutical  and  biotechnology  industries.  Such  rapid  technological  change,  or  the
development by our competitors of technologically improved or differentiated products, could render our products, including our drug delivery technologies, obsolete or noncompetitive.

The pharmaceutical industry has dramatically changed in recent years, largely as a function of the growing importance of generic drugs. The growth of generics (typically small molecules) and of
large  molecules  (biosimilars)  has  been  accelerated  by  the  demand  for  less  expensive  pharmaceutical  products.  As  a  result,  the  pricing  power  of  pharmaceutical  companies  will  be  more  tightly
controlled in the future.

In addition, consolidation has reduced our pool of potential partners and acquisition opportunities within the biopharmaceutical space.

Potential competition for FT218

If FT218 receives FDA approval, it will compete with the currently approved twice-nightly oxybate formulations, as well as a number of daytime wake promoting agents including lisdexamfetamine,
detroamphetamine, methylphenidate, amphetamine, modafinil, and armodafinil, which are widely prescribed, as well as solriamfetol and pitolisant, all of which may be prescribed concomitantly with
sodium oxybate. If approved, we anticipate FT218 may face competition from manufacturers of generic twice-nightly sodium oxybate formulations, who have reached settlement agreements with the
current marketer, which allows for entry of an authorized generic in 2023. In addition, there are other products in development that may be approved in the future that could have an impact on the
narcolepsy treatment market, including, for example, reboxetine, orexin 2 receptor agonists, flecainide / modafinil combination, histamine H3 antagonists/inverse agonists, or GABA  agonists.

controlled release of an active ingredient (expiring in 2025 in the U.S. and 2022 in non-U.S. jurisdictions); (ii) for LiquiTime, patents relating to film-coated microcapsules and a method
comprising  orally  administering  such  microcapsules  to  a  patient  (expiring  in  2023);  and  (iii)  for  Medusa,  patents  relating  to  an  aqueous  colloidal  suspension  of  low  viscosity  based  on
submicronic particles of water-soluble biodegradable polymer PO (polyolefin) carrying hydrophobic groups (expiring in 2023).

The  patent  positions  of  biopharmaceutical  companies  like  us  are  generally  uncertain  and  involve  complex  legal,  scientific  and  factual  questions.  In  addition,  the  coverage  claimed  in  a  patent
application can be significantly reduced before the patent is issued, and patent scope can be reinterpreted by the courts after issuance. Moreover, many jurisdictions permit third parties to challenge
issued patents in administrative proceedings, which may result in further narrowing or even cancellation of patent claims. We cannot predict whether the patent applications we are currently pursuing
will issue as patents in any particular jurisdiction or whether the claims of any of our licensed or owned patents will provide sufficient protection from competitors. Any of our licensed or owned
patents may be challenged, circumvented, or invalidated by third parties. For more information, please see the information set forth under the caption “Risks Related to Our Intellectual Property – If
we cannot adequately protect our intellectual property and proprietary information, we may be unable to effectively compete” in the “Risk Factors” included in Part I, Item 1A of this Annual Report
on Form 10-K.

Supplies and Manufacturing 

We attempt to maintain multiple suppliers in order to mitigate the risk of shortfall and inability to supply market demand. Nevertheless, for FT218, we currently rely on one supplier for sourcing
active pharmaceutical ingredients (“APIs”).

The API in FT218, sodium oxybate, is a Schedule I controlled substance in the U.S., and FT218, if approved by the FDA, will be a Schedule III controlled substance in the U.S. As a result, FT218 is
subject to regulation by the U.S. Drug Enforcement Administration (“DEA”) under the Controlled Substances Act (“CSA”), and its manufacturing and distribution are highly restricted. Quotas from
the DEA are required in order to manufacture and package sodium oxybate and FT218 in the U.S. Similar rules, restrictions and controls apply to FT218 in relevant jurisdictions outside of the U.S.

The API for FT218 is currently manufactured by a single source contract manufacturing organization (“CMO”) in the U.S. The drug product for commercial lots is manufactured outside of the U.S.
by a single source CMO. We will continue to outsource the production of FT218 to current good manufacturing practices (“cGMP”) -compliant, DEA and FDA-audited CMOs pursuant to supply
agreements and have no present plans to acquire manufacturing facilities. We are establishing, and may continue to establish, additional CMOs for the manufacture FT218, including drug product
manufacturing in the U.S.

Government Regulation 

Government authorities in the U.S. at the federal, state, and local level and in other countries extensively regulate, among other things, the research and clinical development, testing, manufacture,
quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-approval monitoring and reporting, marketing, pricing, and export and import of drug
products, such as those we are developing. Generally, before a new drug can be marketed, considerable data demonstrating its quality, safety, and efficacy must be obtained, organized into a format
specific to each regulatory authority, submitted for review, and approved by the regulatory authority.

Drugs 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  regulatory  requirements  at  any  time  during  the  product
development process, approval process, or after approval, may subject an applicant to administrative or judicial

-10-

 
 
sanctions. These sanctions could include, among other actions, the regulatory authority's refusal to approve pending applications, withdrawal of an approval, clinical holds, untitled or warning letters,
voluntary product recalls or withdrawals from the market, product seizures, total or partial suspension of production or distribution, injunctions, debarment, 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.

U.S. Drug Development

In the U.S., the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (“FDCA”) and its implementing regulations. Drugs are also subject to other federal, state, and local statutes and
regulations. Our drug candidates must be approved by the FDA through the NDA process before they may be legally marketed in the U.S. The process required by the FDA before a drug may be
marketed in the U.S. generally involves the following:

•

•

•

•

•

•

•

•

•

completion of extensive preclinical, sometimes referred to as nonclinical, laboratory tests, animal studies, and formulation studies all performed in accordance with applicable regulations,
including the FDA's good laboratory practice (“GLP”) regulations;

submission to the FDA of an Investigational New Drug Application (“IND”), which must become effective before human clinical trials may begin and must be updated annually;

performance  of  adequate  and  well-controlled  human  clinical  trials  in  accordance  with  applicable  IND  and  other  clinical  trial-related  regulations,  sometimes  referred  to  as  good  clinical
practices (“GCPs”) to establish the safety and efficacy of the proposed drug for its proposed indication;

submission to the FDA of a NDA for a new drug;

a determination by the FDA within 60 days of its receipt of a NDA to file the NDA for review;

satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the active pharmaceutical ingredient (“API”) and finished drug product are
produced to assess compliance with the FDA's current good manufacturing practice requirements (“cGMPs”);

potential FDA audit of the clinical trial sites that generated the data in support of the NDA;

payment of user fees for FDA review of the NDA; and

FDA review and approval of the NDA prior to any commercial marketing or sale of the drug in the U.S.

The  data  required  to  support  a  NDA  are  generated  in  two  distinct  development  stages:  preclinical  and  clinical.  The  preclinical  development  stage  generally  involves  synthesizing  the  active
component, developing the formulation, and determining the manufacturing process, as well as carrying out non-human toxicology, pharmacology, and drug metabolism studies in the laboratory,
which support subsequent clinical testing. The conduct of the preclinical tests must comply with federal regulations, including GLPs. The sponsor must submit the results of the preclinical tests,
together with manufacturing information, analytical data, any available clinical data or literature, and a proposed clinical protocol, to the FDA as part of the IND. An IND is a request for authorization
from the FDA to administer an investigational drug product to humans. The central focus of an IND submission is on patient safety and the general investigational plan and the protocol(s) for human
trials. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA raises concerns or questions regarding the proposed clinical trials and places the IND on clinical
hold within that 30-day time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns or questions before the clinical trial can begin. The FDA also may impose a
partial clinical hold that would limit a trial, for example, to certain doses or for a certain length of time or to a certain number of subjects. The FDA may also impose clinical holds on a drug candidate
at any time before or during clinical trials due to safety concerns or non-compliance. Accordingly, we cannot be sure that submission of an IND will result in the FDA allowing clinical trials to begin,
or that, once begun, issues will not arise that could cause the trial to be suspended or terminated.

The clinical-stage of development involves the administration of the drug candidate to human subjects under the supervision of qualified investigators, generally physicians not employed by or under
the trial sponsor's control, in accordance with GCPs, which include the requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials
are conducted under protocols detailing, 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 and assess efficacy.

-11-

Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part of the IND. Further, each clinical trial must be reviewed and approved by an independent
institutional  review  board  (“IRB”)  at  or  servicing  each  institution  at  which  the  clinical  trial  will  be  conducted.  An  IRB  is  charged  with  protecting  the  welfare  and  rights  of  trial  participants  and
considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the informed
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.  There  are  also  requirements  governing  the
reporting of ongoing clinical trials and completed clinical trial results to public registries.

Clinical trials are generally conducted in three sequential phases that may overlap or be combined, known as Phase 1, Phase 2, and Phase 3 trials. Phase 1 trials generally involve a small number of
healthy volunteers who are initially exposed to a single dose and then multiple doses of the drug candidate. The primary purpose of these clinical trials is to assess the metabolism, pharmacologic
action, side effects, tolerability, and safety of the drug. Phase 2 clinical trials typically involve studies in disease-affected patients to determine the dose required to produce the desired benefits. At the
same time, safety and further pharmacokinetics (“PK”) and pharmacodynamics (“PD”) information is collected, as well as identification of possible adverse effects and safety risks and preliminary
evaluation of efficacy. Phase 3 trials generally involve large numbers of patients at multiple sites (from several hundred to several thousand subjects) and are designed to provide the data necessary to
demonstrate the efficacy of the drug for its intended use, its safety in use, and to establish the overall benefit/risk relationship of the drug and provide an adequate basis for physician labeling. The
duration of treatment is often extended to mimic the actual use of a drug during marketing. Generally, two adequate and well-controlled Phase 3 trials are required by the FDA for approval of a NDA.
Post-approval  trials,  sometimes  referred  to  as  Phase  4  clinical  trials,  may  be  conducted  after  initial  marketing  approval.  These  trials  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 clinical trials.

Progress reports detailing the results of the clinical trials 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 reactions, any finding from other clinical studies, tests in laboratory animals, or in vitro testing that suggests a significant risk for human subjects, or any clinically important
increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The sponsor must submit an IND safety report within 15 calendar days after the
sponsor determines that the information qualifies for reporting. The sponsor also must notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within seven calendar
days after the sponsor's initial receipt of the information. Phase 1, Phase 2, and Phase 3 trials may not be completed successfully within any specified period, if at all. There also are requirements
governing the reporting of ongoing clinical trials and completed clinical trial results to public registries. Information about certain clinical trials, including clinical trial results, must be submitted
within specific timeframes for publication on the www.clinicaltrials.gov website.

The FDA, the IRB, 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 drug 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 or not a trial may move forward at designated check points based on access to certain
data from the trial. We 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  drug  as  well  as  finalize  a  process  for  manufacturing  the  drug  in
commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things,
cGMPs  impose  extensive  procedural,  substantive,  and  recordkeeping  requirements  to  ensure  and  preserve  the  long-term  stability  and  quality  of  the  final  drug  product.  Additionally,  appropriate
packaging must be selected and tested, and stability studies must be conducted to demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf life.

NDA and the FDA Review Process

Following  trial  completion,  trial  data  are  analyzed  to  assess  safety  and  efficacy.  The  results  of  preclinical  studies  and  clinical  trials  are  then  submitted  to  the  FDA  as  part  of  a  NDA,  along  with
proposed labeling for the drug and information about the manufacturing process and facilities that will be used to ensure drug quality, results of analytical testing conducted on the chemistry of the
drug, and other relevant information. The NDA is a request for approval to market the drug and must contain adequate evidence of safety and efficacy, which is demonstrated by extensive preclinical
and clinical testing. Data may come from company-sponsored clinical trials intended to test the safety and efficacy of a use of a drug, or from a number of

-12-

alternative sources, including studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in quality and quantity to establish the safety and efficacy of the
investigational drug product for a particular indication or indications to the satisfaction of the FDA. FDA approval of a NDA must be obtained before a drug may be offered for sale in the U.S.

Under the PDUFA, as amended, each NDA must be accompanied by a user fee. The FDA adjusts the PDUFA user fees on an annual basis. PDUFA also imposes an annual prescription drug product
program fee for human drugs. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a small business. Additionally,
no user fees are assessed on NDAs for products designated as orphan drugs, unless the product also includes a non-orphan indication.

Within 60 days following submission of an original NDA, the FDA reviews the application to determine if it is substantially complete before the agency accepts it for filing. The FDA may refuse to
file any NDA that it deems incomplete or not properly reviewable at the time of submission, including for failure to pay required fees, and may request additional information. In this event, the
application must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing. The FDA typically makes a decision on
whether to accept a NDA for filing within 60 days of receipt. Once the submission is accepted for filing, the FDA begins an in-depth, substantive review of the NDA. Under the performance goals
established under the PDUFA, the FDA has agreed to review 90% of standard NDAs for new molecular entities (“NMEs”) in ten months from the filing date and 90% of priority NME NDAs in six
months from the filing date. The goals for reviewing standard and priority non-NME NDAs are ten months and six months, respectively, measured from the receipt date of the application. The FDA
does not always meet its PDUFA goal dates for standard and priority NDAs, and the review process is often significantly extended by FDA requests for additional information or clarification.

After the NDA submission is accepted for filing, the FDA reviews the NDA to determine, among other things, whether the proposed drug is safe and effective for its intended use, and whether the
drug is being manufactured in accordance with cGMP to assure and preserve the drug's identity, strength, quality, and purity. The FDA may refer applications for novel drugs or drug candidates that
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. In the course of its review, the FDA may re-analyze the clinical trial data, which could result in extensive discussions between the FDA and the applicant during the review process. The
review and evaluation of a NDA 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 a NDA, the FDA typically conducts a pre-approval inspection of the manufacturing facilities for the new drug to determine whether they comply with cGMPs. The FDA will not
approve the drug unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the drug within
required specifications. In addition, before approving a NDA, 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  where  the  drug  product  and/or  its  API  will  be  produced,  it  may  issue  an  approval  letter  or  a  Complete  Response  Letter.  An  approval  letter
authorizes commercial marketing of the drug with specific prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete
and the application is not ready for approval. A Complete Response Letter usually describes all of the specific deficiencies in the NDA identified by the FDA. The Complete Response Letter may
require  additional  clinical  data  and/or  an  additional  pivotal  clinical  trial(s),  and/or  other  significant,  expensive  and  time-consuming  requirements  related  to  clinical  trials,  preclinical  studies,  or
manufacturing. If a Complete Response Letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies identified in the letter, challenge the determination set forth in
the letter by requesting a hearing, or withdraw the application. Even if such data and information are submitted, the FDA may ultimately decide that the NDA 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 drug product for marketing in the U.S. If a drug receives marketing approval, the approval may be significantly limited to specific
diseases,  dosages,  or  patient  subgroups,  or  the  indications  for  use  may  otherwise  be  limited,  which  could  restrict  the  commercial  value  of  the  drug.  Further,  the  FDA  may  require  that  certain
contraindications, warnings, precautions, or adverse events be included in the drug labeling or may condition the approval of the NDA on other changes to the proposed labeling, development of
adequate  controls  and  specifications,  or  a  commitment  to  conduct  post-marketing  testing  or  clinical  trials,  and  surveillance  to  monitor  the  effects  of  approved  drugs.  For  example,  the  FDA  may
require Phase 4 testing which involves clinical trials designed to further assess a drug's safety and may require testing and surveillance programs to monitor the safety of approved drugs that have
been

-13-

commercialized. The FDA may also place other conditions on approvals including the requirement for a Risk Evaluation and Mitigation Strategy (“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 drugs. Drug approvals may be withdrawn for non-compliance with regulatory
standards or if problems occur following initial marketing.

Pediatric Information and Exclusivity

Under the Pediatric Research Equity Act (“PREA”), as amended, a NDA or supplement to a NDA for a drug that includes a new active ingredient, new indication, new dosage form, new dosing
regimen, or new route of administration must contain data to assess the safety and efficacy of the drug for the claimed indications in all relevant pediatric subpopulations and to support dosing and
administration for each pediatric subpopulation for which the drug is safe and effective. The FDA may grant deferrals for submission of data or full or partial waivers.

A sponsor who is planning to submit a marketing application for a drug subject to PREA must submit an initial Pediatric Study Plan (“PSP”) within 60 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  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.

A drug product can also obtain pediatric exclusivity in the U.S. is another type of regulatory market exclusivity in the U.S. Pediatric exclusivity, if granted, adds six months to existing exclusivity
periods and patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric trial in
accordance with a FDA-issued "Written Request" for such a trial.

Orphan Drug Designation

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 U.S., or if it affects 200,000 or more individuals in
the U.S., there is no reasonable expectation that the cost of developing and marketing the drug for this type of disease or condition will be recovered from sales in the U.S. Orphan drug designation
entitles a party to potential financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-fee waivers. In addition, if a product receives the first FDA
approval for the indication for which it has orphan designation, the product is entitled to orphan drug exclusivity, which means the FDA may not approve any other application to market the same
drug for the same indication for a period of seven years, except in limited circumstances, such as a showing of clinical superiority over the product with orphan exclusivity.

Orphan drug exclusivity may be lost if the FDA determines that the request for designation was materially defective or if the manufacturer is unable to assure sufficient quantity of the drug to meet
the needs of patients with the rare disease or condition. Orphan drug designation must be requested before submitting an application for marketing approval. Orphan drug designation does not convey
any advantage in, or shorten the duration of, the regulatory review and approval process.

505(b)(2) New Drug Applications

As an alternative path to FDA approval for modifications to formulations or uses of products previously approved by the FDA pursuant to an NDA, an applicant may submit an NDA under Section
505(b)(2) of the FDCA. Section 505(b)(2) was enacted as part of the Hatch-Waxman Amendments and permits the filing of an NDA where at least some of the information required for approval
comes from studies not conducted by, or for, the applicant, and for which the applicant has not obtained a right of reference. In addition, if the 505(b)(2) applicant can establish that reliance on the
FDA’s previous findings of safety and effectiveness is scientifically and legally appropriate, it may eliminate the need to conduct certain preclinical studies or clinical trials of the new product. The
FDA may also require companies to perform additional bridging studies or measurements, including clinical trials, to support the change from the previously approved reference drug. The FDA may
then approve the new drug candidate for all, or some, of the label indications for which the reference drug has been approved, as well as for any new indication sought by the 505(b)(2) applicant.

-14-

Post-Marketing Requirements

Following approval of a new drug, a pharmaceutical company and the approved drug are subject to continuing regulation by the FDA, including, among other things, establishment registration and
drug listing, monitoring and recordkeeping activities, reporting to the applicable regulatory authorities of adverse experiences with the drug, providing the regulatory authorities with updated safety
and efficacy information, drug sampling and distribution requirements, and complying with promotion and advertising requirements, which include, among others, standards for direct-to-consumer
advertising, restrictions on promoting drugs for uses or in patient populations that are not described in the drug's approved labeling (known as off-label promotion), limitations on industry-sponsored
scientific and educational activities, and requirements for promotional activities involving the internet. Although physicians may prescribe legally available drugs for off-label uses, the FDA takes the
position that manufacturers may not market or promote such off-label uses. Modifications or enhancements to the drug or its labeling or changes of the site or process of manufacture are often subject
to the approval of the FDA and other regulators, which may or may not be received or may result in a lengthy review process.

Prescription drug advertising is subject to federal, state, and foreign regulations. In the U.S., the FDA regulates prescription drug promotion, including direct-to-consumer advertising. Prescription
drug  promotional  materials  must  be  submitted  to  the  FDA  in  conjunction  with  their  first  use.  Any  distribution  of  prescription  drugs  and  pharmaceutical  samples  must  comply  with  the  U.S.
Prescription Drug Marketing Act, a part of the FDCA. The Drug Supply Chain Security Act (“DSCSA”) was enacted in 2013 with the aim of building an electronic system to identify and trace
certain prescription drugs distributed in the U.S. The DSCSA mandates phased-in and resource-intensive obligations for pharmaceutical manufacturers, wholesale distributors, and dispensers over a
10-year period that is expected to culminate in November 2023. The law’s requirements include the quarantine and prompt investigation of a suspect product to determine if it is illegitimate, and
notifying trading partners and the FDA of any illegitimate product. Drug manufacturers and other parties involved in the supply chain for prescription drug products must also comply with product
tracking  and  tracking  requirements,  such  as  placing  a  unique  product  identifier  on  prescription  drug  packages.  This  identifier  consists  of  the  National  Drug  Code,  serial  number,  lot  number,  and
expiration date, in the form of a 2-dimensional data matrix barcode that can be read by humans and machines.

In the U.S., once a drug is approved, its manufacture is subject to comprehensive and continuing regulation by the FDA. FDA regulations require that drugs be manufactured in specific facilities per
the NDA approval and in accordance with cGMP. We rely, and expect to continue to rely, on third parties for the production of clinical and commercial quantities of our approved drug and drug
candidates  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 manufacturers and other entities involved in the manufacture and distribution of approved drugs 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 cGMP
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 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 cGMP, could result in enforcement actions that interrupt the operation of any
such facilities or the ability to distribute drugs manufactured, processed, or tested by them.

The FDA also may require post-approval testing, sometimes referred to as Phase 4 testing, risk minimization action plans, and post-marketing surveillance to monitor the effects of an approved drug
or place conditions on an approval that could restrict the distribution or use of the drug.

The FDA may issue enforcement letters or withdraw the approval of the product if compliance with regulatory requirements and standards is not maintained or if problems occur after the drug or
biologic reaches the market. Corrective action could delay drug or biologic distribution and require significant time and financial expenditures. Later discovery of previously unknown problems with
a drug or biologic, including AEs of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may require revisions to the approved
labeling to add new safety information, including the addition of new warning and contraindications; imposition of post-market studies or clinical trials to assess new safety risks; or imposition of
distribution or other restrictions under a REMS program. Other potential consequences include, among other things:

• mandated corrective advertising or communications with doctors;

-15-

•

•

•

•

•

restrictions on the marketing or manufacturing of the drug or biologic, suspension of the approval, complete withdrawal of the drug from the market or product recalls;

fines, warning letters or holds on post-approval clinical trials;

refusal of the FDA to approve applications or supplements to approved applications, or suspension or revocation of drug or biologic approvals;

drug or biologic seizure or detention, or refusal to permit the import or export of drugs; or

injunctions or the imposition of civil or criminal penalties.

U.S. Marketing Exclusivity

Marketing exclusivity provisions under the FDCA can delay the submission or the approval of certain marketing applications for competing products. The FDCA provides a five-year period of non-
patent marketing exclusivity within the U.S. to the first applicant to obtain approval of a NDA for a new chemical entity. A drug is a new chemical entity if the FDA has not previously approved any
other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an
abbreviated new drug application (“ANDA”) or a 505(b)(2) NDA submitted by another company for another drug based on the same active moiety, regardless of whether the drug is intended for the
same indication as the original innovator drug or for another indication. However, an application may be submitted after four years if it contains a certification of patent invalidity or non-infringement
to one of the patents listed with the FDA by the innovator NDA holder. The FDCA also provides three years of marketing exclusivity for a NDA, or supplement to an existing NDA, if new clinical
investigations,  other  than  bioavailability  studies,  that  were  conducted  or  sponsored  by  the  applicant  are  deemed  by  the  FDA  to  be  essential  to  the  approval  of  the  application,  for  example  new
indications, dosages, or strengths of an existing drug. This three-year exclusivity covers only the modification for which the drug received approval on the basis of the new clinical investigations and
does not prohibit the FDA from approving ANDAs or 505(b)(2) applications for drugs containing the active agent for the original indication or condition of use. Five-year and three-year exclusivity
will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and
adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

Other Regulatory Matters

Manufacturing, sales, promotion, and other activities following drug approval are also subject to regulation by numerous regulatory authorities in addition to the FDA, including, in the U.S., the
Centers for Medicare & Medicaid Services (“CMS”), other divisions of the U.S. Department of Health and Human Services (“HHS”), the Drug Enforcement Administration for controlled substances,
the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency, and state and local governments.
In the U.S., sales, marketing, and scientific/educational programs must also comply with state and federal fraud and abuse laws. Pricing and rebate programs must comply with the Medicaid rebate
requirements of the U.S. Omnibus Budget Reconciliation Act of 1990 and more recent requirements in the Patient Protection and Affordable Care Act as amended by the Health Care and Education
Reconciliation Act of 2010 (or collectively, the ACA). If drugs are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and
requirements apply. The handling of any controlled substances must comply with the U.S. Controlled Substances Act and Controlled Substances Import and Export Act. Drugs must meet applicable
child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act. Manufacturing, sales, promotion, and other activities are also potentially subject to federal and state consumer
protection and unfair competition laws.

We are subject to numerous foreign, federal, state, and local 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.  In  addition,  our  leasing  and  operation  of  real  property  may  subject  us  to  liability  pursuant  to  certain  U.S.  environmental  laws  and
regulations, under which current or previous owners or operators of real property and entities that disposed or arranged for the disposal of hazardous substances may be held strictly, jointly, and
severally liable for the cost of investigating or remediating contamination caused by hazardous substance releases, even if they did not know of and were not responsible for the releases.

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

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 or seizure of drugs, total or partial suspension of production, denial or withdrawal of product approvals, 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 efficacy of
a product could lead the FDA to modify or withdraw product approval. Prohibitions or restrictions on sales or withdrawal of our approved drug or any 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 recall or discontinuation of our product; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could
adversely affect the operation of our business.

Other Regulation

Controlled Substances Regulations

Narcotics  and  other  APIs,  such  as  sodium  oxybate,  are  “controlled  substances”  under  the  U.S.  federal Controlled  Substances  Act  (“CSA”).  The  CSA  Title  II  of  the  Comprehensive  Drug  Abuse
Prevention and Control Act of 1970, regulates the manufacture and distribution of narcotics and other controlled substances, including stimulants, depressants and hallucinogens in the U.S. The CSA
is administered by the Drug Enforcement Administration (“DEA”), a division of the U.S. Department of Justice, and is intended to prevent the abuse or diversion of controlled substances into illicit
channels of commerce. The DEA classifies controlled substances into five schedules. Schedule I substances by definition have a high potential for abuse, have no currently “accepted medical use” in
the U.S., lack accepted safety for use under medical supervision, and may not be prescribed, marketed or sold in the U.S. Pharmaceutical products approved for use in the U.S. may be listed as
Schedule II, III, IV or V, with Schedule II substances considered to present the highest potential for abuse or dependence and Schedule V substances the lowest relative risk of abuse. The API in
FT218, sodium oxybate, is a Schedule I controlled substance in the U.S., and FT218, if approved by the FDA, will be a Schedule III controlled substance in the U.S

For drugs manufactured in the U.S., the DEA establishes annually an aggregate quota for the amount of substances within Schedules I and II that may be manufactured or produced in the U.S. based
on  the  DEA’s  estimate  of  the  quantity  needed  to  meet  legitimate  medical,  scientific,  research  and  industrial  needs.  The  quotas  apply  equally  to  the  manufacturing  of  the  active  pharmaceutical
ingredient and production of dosage forms. The DEA may adjust aggregate production quotas a few times per year, and individual manufacturing or procurement quotas from time to time during the
year, although the DEA has substantial discretion in whether or not to make such adjustments for individual companies.

The DEA limits the quantity of certain Schedule I controlled substances that may be manufactured and procured in the U.S. in any given calendar year through a quota system and, as a result, quotas
from the DEA are required in order to manufacture sodium oxybate and FT218 in the U.S. Accordingly, we require DEA quotas for sodium oxybate and FT218, until approved, if ever, by the FDA.

If  approved  by  the  FDA,  FT218  will  be  a  Schedule  III  controlled  substance  and  subject  to  DEA  import  volume  limits  and  state  regulations  relating  to  manufacturing,  storage,  distribution  and
physician  prescription  procedures,  including  limitations  on  prescription  refills.  In  addition,  the  third  parties  who  perform  our  clinical  and  commercial  manufacturing,  distribution,  dispensing  and
clinical studies for FT218 are required to maintain necessary DEA registrations and state licenses. The DEA periodically inspects facilities for compliance with its rules and regulations.

Any person or firm that manufactures, distributes, dispenses, imports, or exports any controlled substance (or proposes to do so) must register with the DEA. The applicant must register for a specific
business activity related to controlled substances, including manufacturing or distributing, and may engage in only the activity or activities for which it is registered. The DEA conducts periodic
inspections  of  registered  establishments  that  handle  controlled  substances.  Failure  to  comply  with  relevant  DEA  regulations,  particularly  as  manifested  in  the  loss  or  diversion  of  controlled
substances, can result in regulatory action including civil penalties, refusal to renew necessary registrations, or proceedings to revoke those registrations. In certain circumstances, violations can lead
to criminal prosecution. In addition to these federal statutory and regulatory obligations, there may be state and local laws and regulations relevant to the handling of controlled substances or listed
chemicals. Governments outside of the U.S. have similar controlled substance laws, regulations and requirements in their respective jurisdictions.

Healthcare Laws

Healthcare providers and third-party payors in the United States and elsewhere play a primary role in the recommendation and prescription of pharmaceutical products. Arrangements with third-party
payors  and  customers  can  expose  pharmaceutical  manufactures  to  broadly  applicable  fraud  and  abuse  and  other  healthcare  laws  and  regulations,  including,  without  limitation,  the  federal  Anti-
Kickback  Statute  and  the  federal  False  Claims  Act  (“FCA”),  which  may  constrain  the  business  or  financial  arrangements  and  relationships  through  which  companies  research,  sell,  market  and
distribute  pharmaceutical  products.  In  addition,  transparency  laws  and  patient  privacy  laws  can  apply  to  the  activities  of  pharmaceutical  manufactures.  The  applicable  federal,  state  and  foreign
healthcare laws and regulations that can affect a pharmaceutical company’s operations include without limitation:

•

•

•

The federal Anti-Kickback Statute, which prohibits, among other things, knowingly and willfully soliciting, receiving, offering or paying any remuneration (including any kickback, bribe, or
rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce, or in return for, either the referral of an individual, or the purchase, lease, order or recommendation of any
good, facility, item or service for which payment may be made, in whole or in part, under the Medicare and Medicaid programs, or other federal healthcare programs. A person or entity can
be found guilty of violating the statute 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 federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the FCA. The Anti-Kickback Statute has been interpreted to apply to
arrangements  between  pharmaceutical  manufacturers  on  the  one  hand  and  prescribers,  purchasers,  and  formulary  managers  on  the  other.  There  are  a  number  of  statutory  exceptions  and
regulatory  safe  harbors  protecting  some  common  activities  from  prosecution,  but  such  exceptions  and  safe  harbors  are  drawn  narrowly  and  require  strict  compliance  in  order  to  offer
protection;

The federal civil and criminal false claims laws, including the FCA, and civil monetary penalty laws, which prohibit any person or entity from, among other things, knowingly presenting, or
causing to be presented, a false, fictitious or fraudulent claim for payment to, or approval by, the federal government or knowingly making, using or causing to be made or used a false record
or statement, including providing inaccurate billing or coding information to customers or promoting a product off-label, material to a false or fraudulent claim to the federal government. As
a result of a modification made by the Fraud Enforcement and Recovery Act of 2009, a claim includes “any request or demand” for money or property presented to the federal government.
In addition, 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. 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;

The  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996  (HIPAA),  which  created  federal  criminal  statutes  that  prohibit,  among  other  things,  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 statements 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 can be found guilty of violating HIPAA without actual knowledge of the statute or specific
intent to violate it;

• HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (HITECH), and their respective implementing regulations, which impose, among
other things, specified requirements relating to the privacy, security and transmission of individually identifiable health information held by covered entities and their business associates as
well  as  their  covered  subcontractors.  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;

•

The federal legislation commonly referred to as the Physician Payments Sunshine Act, created under the ACA, and its implementing regulations, which 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  certain  exceptions)  to  report
annually  to  CMS,  information  related  to  payments  or  other  transfers  of  value  made  to  physicians  (defined  to  include  doctors,  dentists,  optometrists,  podiatrists  and  chiropractors)  and
teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. Effective January 1,

-18-

 
2022,  covered  manufacturers  also  are  required  to  report  information  regarding  their  payments  and  other  transfers  of  value  to  physician  assistants,  and  nurse  practitioners,  clinical  nurse
specialists, anesthesiologist assistants, certified registered nurse anesthetists and certified nurse midwives during the previous year;

•

•

Federal government price reporting laws, which require us 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

• Analogous state laws and regulations, including: state anti-kickback and false claims laws, which may apply to our business practices, including, but not limited to, research, distribution,
sales and marketing arrangements and claims involving healthcare items or services reimbursed by any third-party payor, including private insurers; state laws that require pharmaceutical
companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the U.S. federal government, or otherwise
restrict payments that may be made to healthcare providers and other potential referral sources; state and local laws that require drug manufacturers to report information related to payments
and other transfers of value to physicians and other healthcare providers or marketing expenditures; state laws that require the reporting of information related to drug pricing; state and local
laws requiring the registration of pharmaceutical sales representatives; and state laws governing the privacy and security of health information in some circumstances, many of which differ
from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

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.

Coverage and Reimbursement

Sales  of  any  product  depend,  in  part,  on  the  extent  to  which  such  product  will  be  covered  by  third-party  payors,  such  as  federal,  state,  and  foreign  government  healthcare  programs,  commercial
insurance and managed healthcare organizations, and the level of reimbursement for such product by third-party payors. Decisions regarding the extent of coverage and amount of reimbursement to
be provided are made on a plan-by-plan basis. These third-party payors are increasingly reducing coverage and reimbursement for medical products, drugs and services. For products administered
under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate
reimbursement for the product itself or the treatment or procedure in which the product is used may not be available, which may impact physician utilization.

In order to secure coverage and reimbursement for any product that might be approved for sale, a company may need to conduct expensive pharmacoeconomic studies in order to demonstrate the
medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain FDA or other comparable regulatory approvals. Additionally, companies may also need to provide
discounts to purchasers, private health plans or government healthcare programs. Nonetheless, product candidates may not be considered medically necessary or cost effective. A decision by a third-
party payor not to cover a product could reduce physician utilization once the product is approved and have a material adverse effect on sales, our operations and financial condition. Factors that
payors consider in determining reimbursement are based on whether the product is (i) a covered benefit under its health plan; (ii) safe, effective, and medically necessary; (iii) appropriate for the
specific patient; (iv) cost-effective; and (v) neither experimental nor investigational. Additionally, a third-party payor’s decision to provide coverage for a product does not imply that an adequate
reimbursement rate will be approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage and reimbursement for the
product and the level of coverage and reimbursement can differ significantly from payor to payor.

The containment of healthcare costs has become a priority of federal, state and foreign governments and the prices of products have been a focus in this effort. Governments have shown significant
interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic products. Adoption of price controls and
cost-containment  measures  and  adoption  of  more  restrictive  policies  in  jurisdictions  with  existing  controls  and  measures,  could  further  limit  a  company’s  revenue  generated  from  the  sale  of  any
approved products. Coverage policies and third-party payor reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for
which a company or its collaborators receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future. Decreases in third-party reimbursement
for any product or a

-19-

decision by a third-party payor not to cover a product could reduce physician usage and patient demand for the product and also have a material adverse effect on sales.

Healthcare Reform

In both the United States and certain foreign jurisdictions, there have been, and continue to be, a number of legislative and regulatory changes to the health care system. Among policy makers and
payors  in  the  United  States  and  elsewhere,  there  is  significant  interest  in  promoting  changes  in  healthcare  systems  with  the  stated  goals  of  containing  healthcare  costs,  improving  quality  and/or
expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. In particular, in
2010, the ACA was enacted, which, among other things, increased the minimum Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program, extended the Medicaid
Drug  Rebate  Program  to  utilization  of  prescriptions  of  individuals  enrolled  in  Medicaid  managed  care  organizations,  subjected  manufacturers  to  new  annual  fees  and  taxes  for  certain  branded
prescription drugs, and provided incentives to programs that increase the federal government’s comparative effectiveness research.

Since its enactment, there have been numerous judicial, administrative, executive, and legislative efforts to expand, repeal, replace or modify the ACA, some of which have been successful, in part, in
modifying the law, as well as court challenges to the constitutionality of the law. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by
several states without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an executive order to initiate a special enrollment period
from  February  15,  2021  through  August  15,  2021  for  purposes  of  obtaining  health  insurance  coverage  through  the  ACA  marketplace.  The  executive  order  also  instructed  certain  governmental
agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that
include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how other healthcare reform
measures of the Biden administration or other efforts, if any, to challenge, repeal or replace the ACA will impact our business.

Prior to the Biden administration, on October 13, 2017, former President Trump signed an Executive Order terminating the cost-sharing subsidies that reimburse insurers under the ACA. The former
Trump  administration  concluded  that  cost-sharing  reduction  (“  CSR”),  payments  to  insurance  companies  required  under  the  ACA  have  not  received  necessary  appropriations  from  Congress  and
announced that it will discontinue these payments immediately until those appropriations are made. Several state attorneys general filed suit to stop the administration from terminating the subsidies,
but their request for a restraining order was denied by a federal judge in California on October 25, 2017. On August 14, 2020, the U.S. Court of Appeals for the Federal Circuit ruled in two separate
cases that the federal government is liable for the full amount of unpaid CSRs for the years preceding and including 2017. For CSR claims made by health insurance companies for years 2018 and
later, further litigation will be required to determine the amounts due, if any. Further, on June 14, 2018, the U.S. Court of Appeals for the Federal Circuit ruled that the federal government was not
required to pay more than $12 billion in ACA risk corridor payments to third-party payors who argued the payments were owed to them. On April 27, 2020, the United States Supreme Court reversed
the  U.S.  Court  of  Appeals  for  the  Federal  Circuit's  decision  and  remanded  the  case  to  the  U.S.  Court  of  Federal  Claims,  concluding  the  government  has  an  obligation  to  pay  these  risk  corridor
payments under the relevant formula. It is unclear what impact these rulings will have on our business.

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

• On August 2, 2011, the U.S. Budget Control Act of 2011, among other things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year. These reductions went
into effect on April 1, 2013 and, due to subsequent legislative amendments to the statute, will remain in effect through 2030, with the exception of a temporary suspension from May 1, 2020
through March 31, 2022 due to the COVID-19 pandemic. Following the temporary suspension, a 1% payment reduction will occur beginning April 1, 2022 through June 30, 2022, and the
2% payment reduction will resume on July 1, 2022.

• On January 2, 2013, the U.S. American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers.

• 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.

-20-

• On  May  30,  2018,  the  Right  to  Try  Act,  was  signed  into  law.  The  law,  among  other  things,  provides  a  federal  framework  for  certain  patients  to  access  certain  investigational  new  drug
products  that  have  completed  a  Phase  1  clinical  trial  and  that  are  undergoing  investigation  for  FDA  approval.  Under  certain  circumstances,  eligible  patients  can  seek  treatment  without
enrolling  in  clinical  trials  and  without  obtaining  FDA  permission  under  the  FDA  expanded  access  program.  There  is  no  obligation  for  a  pharmaceutical  manufacturer  to  make  its  drug
products available to eligible patients as a result of the Right to Try Act.

• 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.

• On December 20, 2019, former President Trump signed into law the Further Consolidated Appropriations Act (H.R. 1865), which repealed the Cadillac tax, the health insurance provider tax,

and the medical device excise tax. It is impossible to determine whether similar taxes could be instated in the future.

There has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. At a federal level, President
Biden signed an Executive Order on July 9, 2021 affirming the administration’s policy to (i) support legislative reforms that would lower the prices of prescription drug and biologics, including by
allowing  Medicare  to  negotiate  drug  prices,  by  imposing  inflation  caps,  and,  by  supporting  the  development  and  market  entry  of  lower-cost  generic  drugs  and  biosimilars;  and  (ii)  support  the
enactment of a public health insurance option. Among other things, the Executive Order also directs HHS to provide a report on actions to combat excessive pricing of prescription drugs, enhance the
domestic drug supply chain, reduce the price that the Federal government pays for drugs, and address price gouging in the industry; and directs the FDA to work with states and Indian Tribes that
propose to develop section 804 Importation Programs in accordance with the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, and the FDA’s implementing regulations.
FDA released such implementing regulations on September 24, 2020, which went into effect on November 30, 2020, providing guidance for states to build and submit importation plans for drugs
from Canada. On September 25, 2020, CMS stated drugs imported by states under this rule will not be eligible for federal rebates under Section 1927 of the Social Security Act and manufacturers
would not report these drugs for “best price” or Average Manufacturer Price purposes. Since these drugs are not considered covered outpatient drugs, CMS further stated it will not publish a National
Average Drug Acquisition Cost for these drugs. If implemented, importation of drugs from Canada may materially and adversely affect the price we receive for any of our product candidates. Further,
on November 20, 2020 CMS issued an Interim Final Rule implementing the Most Favored Nation (“MFN”) Model under which Medicare Part B reimbursement rates would have been be calculated
for certain drugs and biologicals based on the lowest price drug manufacturers receive in Organization for Economic Cooperation and Development countries with a similar gross domestic product
per capita. However, on December 29, 2021 CMS rescinded the Most Favored Nations rule. Additionally, on November 30, 2020, HHS published a regulation removing safe harbor protection for
price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The rule also
creates  a  new  safe  harbor  for  price  reductions  reflected  at  the  point-of-sale,  as  well  as  a  safe  harbor  for  certain  fixed  fee  arrangements  between  pharmacy  benefit  managers  and  manufacturers.
Pursuant to court order, the removal and addition of the aforementioned safe harbors were delayed and recent legislation imposed a moratorium on implementation of the rule until January 1, 2026.
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.

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
December 27, 2018, the District Court for the District of Columbia invalidated a reimbursement formula change under the 340B drug pricing program, and CMS subsequently altered the FYs 2019
and 2018 reimbursement formula on specified covered outpatient drugs (“SCODs”). The court ruled this change was not an “adjustment” which was within the secretary of HHS’s discretion to make
but was instead a fundamental change in the reimbursement calculation. However, most recently, on July 31, 2020, the U.S. Court of Appeals for the District of Columbia Circuit overturned the
district court’s decision and found that the changes were within the Secretary’s authority. On September 14, 2020, the plaintiffs-appellees filed a Petition for Rehearing En Banc (i.e., before the full
court), but was denied on October 16, 2020. Plaintiffs-appellees filed a petition for a writ of certiorari at the Supreme Court on February 10, 2021. On Friday July 2, 2021, the Supreme Court granted
the petition. 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.

-21-

Individual  states  in  the  United  States  have  also  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.

Item 1A.    Risk Factors.

An investment in Avadel involves a high degree of risk. You should carefully consider the risks described below, as well as the other information included or incorporated by reference in this Annual
Report on Form 10-K, before making an investment decision. Avadel’s business, financial condition, results of operations and cash flows could be materially adversely affected by any of these risks.
The market or trading price of Avadel’s securities could decline due to any of these risks. In addition, please read “Cautionary Disclosure Regarding Forward-Looking Statements” in this Annual
Report on Form 10-K, where we describe additional uncertainties associated with Avadel’s business and with the forward-looking statements included or incorporated by reference in this Annual
Report on Form 10-K. Please note that additional risks not presently known to us or that we currently deem immaterial may also impair Avadel’s business and operations.

Risks Related to Our Lead Product Candidate, Future Product Candidates Clinical Development and Commercialization

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

We  have  devoted  significant  financial  resources  and  business  efforts  to  the  development  of  our  lead  product  candidate.  We  cannot  be  certain  that  our  lead  product  candidate  or  future  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 in the U.S. and by comparable regulatory authorities in other
countries. We are not permitted to market our lead product candidate or future product candidates in the U.S. until we receive approval of a NDA by 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 regulatory authorities. In addition, approval policies, regulations, 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.

An NDA must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and effectiveness for each desired indication. An NDA must also
include significant information regarding the chemistry, manufacturing and controls for the product. Obtaining approval of an NDA is a lengthy, expensive and uncertain process, and we may not be
successful in obtaining approval. For example, we submitted an NDA to the FDA for FT218 for the treatment of EDS or cataplexy in adults with narcolepsy to the FDA in December 2020 through
the Section 505(b)(2) regulatory pathway. In February 2021, the FDA assigned FT218 a PDFUA target action date of October 15, 2021. In October, the FDA notified us that its review was still
ongoing and action would not be taken by the PDUDFA date. Any delay or setback in the regulatory approval or commercialization of our lead product candidate 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 lead product candidate;
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 candidate
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 in the U.S., including any findings

that the clinical and other benefits of our product candidate 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  our  product  candidate  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 our product candidate, 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 candidate;

-23-

• may audit some or all of our clinical research study sites to determine the integrity of our data and may reject any or all of such data;
• may approve our lead product candidate for fewer or more limited indications than we request, or may grant approval contingent on the performance of costly post-approval clinical trials;
• may change its 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 lead product candidate.

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 or require expensive and time-consuming
clinical trials and/or reporting as conditions of approval. Regulators of other countries and jurisdictions have their own procedures for the approval of product candidates with which we must comply
prior to marketing in those countries or jurisdictions.

We have submitted a NDA for FT218 in the U.S. and will evaluate filing potentially elsewhere. We have determined, following FDA consultation, that the 505(b)(2) approval pathway, which permits
an NDA applicant to rely on the FDA’s previous findings of safety or effectiveness and data from studies that were not conducted by or for the applicant and for which the applicant has not obtained a
right of reference, is the appropriate pathway for a FT218 NDA. There can be no assurances, however, that the 505(b)(2) approval pathway in the U.S., or similar approval pathways outside of the
U.S., will be available for FT218 or that the FDA or other regulatory authorities will approve FT218 through an application based on such pathways.

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 U.S. 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  during  the  period  of  product  development  and  the  emergence  of  new
information regarding our product candidate.

Our business is significantly dependent on the successful development, regulatory approval and commercialization of FT218, our only product candidate.

We have invested substantially all of our efforts and financial resources in the development of FT218, which has not yet been approved for sale or commercial use. Currently, FT218 is our only
product candidate and we have not licensed, acquired, or invented any other product candidates for preclinical or clinical evaluation. This may make an investment in our company riskier than similar
companies that have multiple product candidates in active development and that therefore may be able to better sustain a failure of a lead candidate. The success of our business, including our ability
to finance our company and generate any revenue in the future, will, at this point, depend entirely on the regulatory approval and commercialization of FT218, which may never occur. Any failure to
obtain regulatory approval of FT218 would have a material and adverse impact on our business. Even if we successfully obtain regulatory approvals to market FT218, our revenue will be dependent,
in part, upon the size of the markets in the territories for which we gain regulatory approval. If the markets or patient subsets that we are targeting are not as significant as we estimate, we may not
generate significant revenues from sales of FT218, even if approved.

The commercial success of FT218 will depend on a number of factors, including the following:

•
•
•
•
•
•
•

the timely receipt of necessary marketing approvals from the FDA and similar foreign regulatory authorities;
our ability to raise any additional required capital to support the commercialization on acceptable terms, or at all;
our ability to consistently manufacture FT218 on a timely basis;
our ability to secure and maintain from the U.S. DEA our annual quota for FT218 APIs;
our ability to successfully to develop and implement a REMS for the safe use of FT218;
the prevalence, duration and severity of potential side effects or other safety issues that patients may experience with FT218;
achieving  and  maintaining,  and,  where  applicable,  ensuring  that  our  third-party  contractors  achieve  and  maintain,  compliance  with  our  contractual  obligations  and  with  all  regulatory
requirements applicable to FT218;

-24-

•

•

•

•
•
•
•
•

the  differentiation  of  FT218  from  other  available  approved,  or  investigational,  drugs  and  treatments  of  excessive  daytime  sleepiness  or  cataplexy  in  adults  with  narcolepsy,  and  the
willingness of physicians, operators of hospitals and clinics and patients to adopt and utilize FT218’s once nightly formulation;
our ability to successfully develop a commercial strategy and thereafter commercialize FT218 in the United States and internationally, if approved for marketing, sale and distribution in such
countries and territories, whether alone or in collaboration with others;
the availability of coverage and adequate reimbursement from managed care plans, private insurers, government payors (such as Medicare and Medicaid and similar foreign authorities) and
other third-party payors for FT218;
patients’ ability and willingness to pay out-of-pocket for FT218 in the absence of coverage and/or adequate reimbursement from third-party payor;
acceptance by physicians, payors and patients of the benefits, safety and efficacy of FT218, if approved;
patient demand for FT218, if approved;
our ability to establish and enforce intellectual property rights in and to FT218; and
our ability to avoid third-party patent interference, intellectual property challenges or intellectual property infringement claims.

These  factors,  many  of  which  are  beyond  our  control,  could  cause  us  to  experience  significant  delays  or  an  inability  to  obtain  regulatory  approvals  or  commercialize  FT218.  Even  if  regulatory
approvals are obtained, we may never be able to successfully commercialize FT218. Accordingly, we cannot provide assurances that we will be able to generate sufficient revenue through the sale of
FT218 to continue our business or achieve profitability.

Our lead product candidate and future product candidates may not reach the commercial market for a number of reasons.

Drug development is an inherently uncertain process with a high risk of failure at every stage of development. Successful research and development of pharmaceutical products is difficult, expensive
and time consuming. Many product candidates fail to reach the market. Our success will depend on the development and the successful commercialization of new drugs and products that utilize our
drug delivery technologies.

Even if our product candidates and current drug delivery technologies appear promising during development, there may not be successful commercial applications developed for them for a number of
reasons, including:

the FDA, the EMA, the competent authority of an EU Member State or an IRB, or an Ethics Committee (EU equivalent to IRB), or our partners may delay or halt applicable clinical trials;

•
• we or our partners may face slower than expected rate of patient recruitment and enrollment in clinical trials, or may devote insufficient funding to the clinical trials;
•
• we or our partners may find that certain products cannot be manufactured on a commercial scale and, therefore, may not be economical or feasible to produce;
• we or our partners may face delays in completing our clinical trials due to circumstances outside of our control, including natural disasters, labor or civil unrest, global health concerns or

our drug delivery technologies and drug products may be found to be ineffective or to cause harmful side effects, or may fail during any stage of pre-clinical testing or clinical trials;

•

pandemics or acts of war or terrorism; or
our lead product candidate and future product candidates could fail to obtain regulatory approval or, if approved, could fail to achieve market acceptance, could fail to be included within the
pricing and reimbursement schemes of the U.S. or EU Member States, or could be precluded from commercialization by proprietary rights of third parties.

If we are not able to use the 505(b)(2) regulatory approval pathway for the regulatory approval of FT218 or if the FDA requires additional clinical or nonclinical data to support an NDA under
Section 505(b)(2) than we previously anticipated, it will likely take significantly longer, cost significantly more and be significantly more complicated to gain FDA approval for FT218, and in
any case may not be successful.

We submitted an NDA to the FDA for FT218 for the treatment of cataplexy or EDS in adults with narcolepsy in December 2020 through the Section 505(b)(2) regulatory pathway. The Drug Price
Competition and Patent Term Restoration Act of 1984,

-25-

also known as the Hatch-Waxman Amendments, added Section 505(b)(2) to the Federal Food, Drug, and Cosmetic Act, or the FDCA. In general, Section 505(b)(2) allows an applicant to rely on the
FDA’s prior findings of safety or effectiveness for a listed drug only to the extent that the proposed product in the 505(b)(2) application shares common characteristics with the listed drug, or on
published  literature  that  the  applicant  believes  supports  the  safety  or  efficacy  of  its  proposed  product  but  for  which  it  does  not  have  a  right  of  reference  for  the  underlying  data.  The  505(b)(2)
application must include sufficient data to support differences between the listed drug and the proposed drug in the 505(b)(2) application. If the FDA does not agree that the 505(b)(2) regulatory
pathway is appropriate or scientifically justified for FT218, we may need to conduct additional clinical trials, provide additional data and information and meet additional standards for regulatory
approval. Specifically, the FDA may not agree that we have provided a scientific bridge, through, for example, comparative bioavailability data, to demonstrate that reliance on the prior findings of
safety or efficacy for a listed drug is justified. Although the active ingredient in FT218, sodium oxybate, is approved for the treatment of cataplexy or excessive daytime sleepiness in patients 7 years
of age and older with narcolepsy, it has not previously been approved or demonstrated to be safe for once nightly administration in these indications. If we are unable to establish a bridge between
FT218 and the listed drug upon which we rely to demonstrate that such reliance is justified, we may be required to show safety and efficacy through one or more additional clinical trials. In addition,
if we are unable to utilize the 505(b)(2) pathway, the time and financial resources required to obtain FDA approval for FT218 would likely increase substantially. Moreover, the inability to utilize the
505(b)(2) regulatory pathway could result in new competitive products reaching the market faster than FT218, which could materially adversely impact its competitive position and prospects.

Even  if  we  are  successful  in  pursuing  the  505(b)(2)  regulatory  pathway  for  FT218,  we  cannot  assure  you  that  we  will  receive  the  requisite  or  timely  approval  for  commercialization  of  FT218.
Although the Section 505(b)(2) pathway allows us to rely in part on the FDA’s prior findings of safety or efficacy for approved listed drugs or on published literature for which we do not have a right
of  reference,  the  FDA  may  determine  that  prior  findings  by  the  FDA  or  the  published  literature  that  we  believe  supports  the  safety  or  efficacy  of  FT218  is  insufficient  or  not  applicable  to  our
application or that additional studies will need to be conducted. To the extent that we are relying on the 505(b)(2) regulatory pathway based on the approval of a listed drug for a similar indication, the
FDA may require that we include in the labeling of FT218, if approved, some or all of the safety information that is included in the labeling of the approved listed drug. For example, the labels of
current FDA-approved sodium oxybate products include a black box warning regarding risks of central nervous system depression and abuse and misuse. Moreover, even if FT218 is approved via the
505(b)(2) regulatory pathway, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to other conditions of approval, or may contain requirements
for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product, such as a Risk Evaluation and Mitigation Strategy, or REMS, which is a risk mitigation plan which
could include medication guides, physician communication plans, or elements to assure safe use, or ETASU, such as restricted distribution methods, patient registries and other risk minimization
tools.

Our business depends heavily on our ability to successfully commercialize FT218 in the U.S. and in other jurisdictions where we may obtain marketing approval. There is no assurance that our
commercialization efforts with respect to FT218, if approved, will be successful or that we will be able to generate revenues at the levels or on the timing we expect, or at levels or on the timing
necessary to support our goals.

Our business currently depends heavily on our ability to successfully commercialize FT218 for the treatment of cataplexy or EDS in adults with narcolepsy in the U.S. and in other jurisdictions where
we  may  obtain  marketing  approval.  Even  if  we  obtain  marketing  approval  for  FT218,  we  may  never  be  able  to  successfully  commercialize  our  product  or  meet  our  expectations  with  respect  to
revenues. There is no guarantee that the infrastructure, systems, processes, policies, relationships, and materials we are building for the commercialization of FT218 in the U.S., or that we may build
for  other  jurisdictions  where  we  may  obtain  marketing  approval,  will  be  sufficient  for  us  to  achieve  success  at  the  levels  we  expect.  If  we  are  unable  to  establish  adequate  sales,  marketing  and
distribution  capabilities,  whether  independently  or  with  third  parties,  or  if  we  are  unable  to  do  so  on  commercially  reasonable  terms,  our  business,  results  of  operations,  financial  condition  and
prospects will be materially adversely affected. We may encounter issues, delays or other challenges in launching or commercializing FT218, if approved. For example, our results may be negatively
impacted if we have not adequately sized our field teams or if our targeting strategy is inadequate or if we encounter deficiencies or inefficiencies in our infrastructure or processes.

We may encounter issues and challenges in commercializing FT218, if approved, and generating sufficient revenues to result in a profit. We may also encounter challenges related to reimbursement
of FT218, including potential limitations in the scope, breadth, availability, or amount of reimbursement covering FT218. Similarly, healthcare settings or patients may determine that the financial
burdens of treatment are not acceptable. We may face other limitations or issues related to the price of FT218. Our results may also be negatively impacted if we have not adequately sized our field
teams or our physician segmentation and targeting strategy is inadequate or if we encounter deficiencies or inefficiencies in our infrastructure or processes. Other factors

-26-

that may hinder our ability to successfully commercialize FT218, if approved, and generate sufficient revenues to result in a profit, include:

•
•

•
•

•
•
•

•
•

the acceptance of FT218 by patients and the medical community;
the ability of our third-party manufacturer(s) to manufacture commercial supplies of FT218 in sufficient quantities at acceptable costs, to remain in good standing with regulatory agencies,
maintain applicable registrations and licenses, and to maintain commercially viable manufacturing processes that are, to the extent required, compliant with current Good Manufacturing
Practices, or cGMP, regulations;
our ability to remain compliant with laws and regulations that apply to us and our commercial activities;
FDA-  or  other  foreign  regulatory  agency-mandated  package  insert  requirements  and  successful  completion  of  any  related  FDA  or  other  foreign  regulatory  agency  post-marketing
requirements, including a REMS;
the actual market size for FT218, which may be different than expected;
the length of time that patients who are prescribed our drug remain on treatment;
the sufficiency of our drug supply to meet commercial demand which could be negatively impacted if our projections regarding the potential number of patients are inaccurate, we are subject
to unanticipated regulatory requirements, or our current drug supply is destroyed, or negatively impacted at our manufacturing sites, storage sites, or in transit;
our ability to effectively complete with other therapies; and
our ability to maintain, enforce, and defend third party challenges to our intellectual property rights in and to FT218.

Any of these issues could impair our ability to successfully commercialize our product, if approved, or to generate sufficient revenues to result in a profit or to meet our expectations with respect to
the amount or timing of revenues or profits. Any issues or hurdles related to our commercialization efforts may materially adversely affect our business, results of operations, financial condition, and
prospects. Even if approved, there is no guarantee that we will be successful in our commercialization efforts with respect to FT218. We may also experience significant fluctuations in sales of FT218
from period to period and, ultimately, we may never generate sufficient revenues from FT218 to reach or maintain profitability or sustain our anticipated levels of operations. Any inability on our part
to successfully commercialize FT218 in the U.S. and any other international markets where it may be approved or any significant delay, could have a material adverse impact on our ability to execute
upon our business strategy.

If we are unable to establish adequate sales, marketing and distribution capabilities, whether independently or with third parties, or if we are unable to do so on commercially reasonable terms, our
business, results of operations, financial condition and prospects will be materially adversely affected. We may encounter issues, delays or other challenges in launching or commercializing FT218, if
approved.  For  example,  our  results  may  be  negatively  impacted  if  we  have  not  adequately  sized  our  field  teams  or  if  our  targeting  strategy  is  inadequate  or  if  we  encounter  deficiencies  or
inefficiencies in our infrastructure or processes.

Clinical development of drugs is costly and time-consuming, and the outcomes are uncertain. A failure to prove that FT218 is safe and effective in clinical trials could materially and adversely
affect our business, financial condition, results of operations and growth prospects.

Clinical trials are expensive and can take many years to complete, and the outcome is uncertain. Failure can occur at any time during the clinical trial process. The results of preclinical studies and
early clinical trials of 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 studies and initial clinical testing. For example, we are currently conducting an open-label extension (“OLE”) switch study of FT218,
RESTORE,  to  examine  the  long-term  safety  and  maintenance  of  efficacy  of  FT218  in  patients  with  narcolepsy  who  participated  in  our  REST-ON  trial,  as  well  as  dosing  and  preference  data  for
patients switching from twice-nightly sodium oxybate to once-nightly FT218 regardless if they participated in REST-ON or not. In May 2021, inclusion criteria were expanded to allow for oxybate
naïve patients to enter the study. If any participants in the OLE/switch study report any serious adverse events that are deemed to be related to FT218 or if FT218 is not observed to have long-term
efficacy, our business, financial condition, results of operations and growth prospects could be material and adversely affected.

In addition to issues relating to the results generated in clinical trials, clinical trials can be delayed or halted for a variety of reasons, including delay or failure in:

•

obtaining regulatory approval to commence a trial;

-27-

•

•
•
•
•
•
•

reaching agreement on acceptable terms with prospective contract research organizations (“CROs”) and clinical trial sites, the terms of which can be subject to extensive negotiation and may
vary significantly among different CROs and trial sites;
obtaining institutional review board or ethics committee approval at each site;
recruiting suitable patients to participate in a trial;
having patients complete a trial or return for post-treatment follow-up;
clinical sites dropping out of a trial;
adding new sites; or
obtaining clinical materials or manufacturing sufficient quantities of FT218 for use in clinical trials.

We have limited experience as a commercial drug company targeting an orphan drug disease and the marketing and sale of FT218, if approved, may be unsuccessful or less successful than
anticipated.

We have limited experience as a commercial drug company targeting an orphan disease and there is limited information about our ability to successfully overcome many of the risks and uncertainties
encountered by companies commercializing drugs in the biopharmaceutical industry. To execute our business plan, in addition to successfully obtaining marketing approval and marketing and selling
FT218, we will need to successfully:

establish and maintain our relationships with healthcare providers who will be treating the patients who may receive our drug;
obtain adequate pricing and reimbursement for FT218;
develop and maintain successful strategic alliances; and

•
•
•
• manage our spending as costs and expenses increase due to marketing approvals and commercialization in multiple jurisdictions, if approved.

If we are unsuccessful in accomplishing these objectives, we may not be able to successfully commercialize FT218, raise capital, expand our business or continue our operations.

Our relationships with healthcare providers, physicians, prescribers, purchasers, third-party payors, charitable organizations and patients will be subject to applicable anti-kickback, fraud and
abuse  and  other  healthcare  laws  and  regulations,  which  could  expose  us  to  criminal  sanctions,  civil  penalties,  contractual  damages,  reputational  harm  and  diminished  profits  and  future
earnings.

Healthcare  providers,  physicians  and  third-party  payors  in  the  United  States  and  elsewhere  play  a  primary  role  in  the  recommendation  and  prescription  of  biotechnology  and  biopharmaceutical
products. Arrangements with third-party payors and customers can expose biotechnology and biopharmaceutical manufacturers to broadly applicable fraud and abuse and other healthcare laws and
regulations, including, without limitation, the federal Anti-Kickback Statute, or AKS, and the federal False Claims Act, or FCA, which may constrain the business or financial arrangements and
relationships through which such companies sell, market and distribute biotechnology and biopharmaceutical products. In particular, the research of our product candidates, as well as the promotion,
sales and marketing of healthcare items and services, as well as certain business arrangements in the healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-
dealing  and  other  abusive  practices.  These  laws  and  regulations  may  restrict  or  prohibit  a  wide  range  of  pricing,  discounting,  marketing  and  promotion,  structuring  and  commission(s),  certain
customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper use of information obtained in the course of patient recruitment for
clinical trials. See the section entitled, “Business — Government Regulation — Healthcare laws”.

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

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and
regulations.  Federal  and  state  enforcement  bodies  have  recently  increased  their  scrutiny  of  interactions  between  healthcare  companies  and  healthcare  providers,  which  has  led  to  a  number  of
investigations, prosecutions, convictions and settlements in the healthcare industry.

Ensuring  that  our  internal  operations  and  future  business  arrangements  with  third  parties  comply  with  applicable  healthcare  laws  and  regulations  will  involve  substantial  costs.  It  is  possible  that
governmental authorities will conclude that our business

-28-

practices do 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 the laws described above or any other governmental laws and regulations that may apply to us, we may be subject to significant penalties, including administrative,
civil and criminal penalties, damages, fines, disgorgement, the exclusion from participation in federal and state healthcare programs, individual imprisonment, 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 or other agreement to resolve allegations of non-
compliance with these laws. Further, 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. If any of the physicians or other providers or entities with whom we expect to do
business are found to not be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs
and imprisonment. If any of the above occur, our ability to operate our business and our results of operations could be adversely affected.

Coverage  and  reimbursement  may  be  limited  or  unavailable  in  certain  market  segments  for  our  product  candidates,  if  approved,  which  could  make  it  difficult  for  us  to  sell  any  product
candidates profitably.

The success of our product candidates, if approved, depends on the availability of coverage and adequate reimbursement from third-party payors. We cannot be sure that coverage and reimbursement
will be available for, or accurately estimate the potential revenue from, our product candidates or assure that coverage and reimbursement will be available for any product that we may develop. See
the sections entitled, “Business — Government Regulation — Coverage and Reimbursement”
and “Business — Government Regulation — Healthcare Laws”.

Patients  who  are  provided  medical  treatment  for  their  conditions  generally  rely  on  third-party  payors  to  reimburse  all  or  part  of  the  costs  associated  with  their  treatment.  Coverage  and  adequate
reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and commercial payors is critical to new product acceptance.

Government  authorities  and  other  third-party  payors,  such  as  private  health  insurers  and  health  maintenance  organizations,  decide  which  drugs  and  treatments  they  will  cover  and  the  amount  of
reimbursement. Coverage and reimbursement by a third-party depends upon a number of factors.

In the United States, no uniform policy of coverage and reimbursement for products exists among third- party payors. As a result, obtaining coverage and reimbursement approval of a product from a
government or other third-party payor is a time-consuming and costly process that could require us to provide to each payor supporting scientific, clinical and cost-effectiveness data for the use of our
products  on  a  payor-by-payor  basis,  with  no  assurance  that  coverage  and  adequate  reimbursement  will  be  obtained.  In  the  United  States,  the  principal  decisions  about  reimbursement  for  new
medicines are typically made by the CMS. 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. Even if we obtain coverage for a given product, the resulting reimbursement payment rates might not be adequate for us to achieve or sustain profitability or may require co-
payments that patients find unacceptably high. Additionally, third-party payors may not cover, or provide adequate reimbursement for, long-term follow-up evaluations required following the use of
product candidates, once approved. Patients are unlikely to use our product candidates, once approved, unless coverage is provided and reimbursement is adequate to cover a significant portion of
their cost. There is significant uncertainty related to insurance coverage and reimbursement of newly approved products. It is difficult to predict at this time what third-party payors will decide with
respect to the coverage and reimbursement for our product candidates.

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. Increasingly, third-party payors are 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. In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as average
sales price and best price. Penalties may apply in some cases 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. Payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives.

Moreover, increasing efforts by governmental and other third-party payors in the United States and abroad to cap or reduce healthcare costs may cause such organizations to limit both coverage and
the level of reimbursement for newly approved

-29-

products and, as a result, they may not cover or provide adequate payment for our product candidates. 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 U.S. Congressional inquiries and proposed and enacted 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.

We expect that healthcare reform measures that may be adopted in the future may result in more rigorous coverage criteria and in additional downward pressure on the price that we receive for any
approved  product.  The  implementation  of  cost  containment  measures  or  other  healthcare  reforms  may  prevent  us  from  being  able  to  generate  revenue,  attain  profitability,  or  commercialize  our
products. Legislative and regulatory proposals have been made to expand post-approval requirements and restrict sales and promotional activities for pharmaceutical products. 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 or
clearances of our product candidates, if any, may be. It is also possible that additional governmental action is taken in response to the COVID-19 pandemic.

In addition, 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 European Union provides options for its Member States to restrict the range of medicinal products for which their national health insurance systems provide reimbursement
and to control the prices of medicinal products for human use. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost
effectiveness of a particular product candidate to currently available therapies. 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 European Union do not follow price
structures of the U.S. and generally prices tend to be significantly lower.

Ongoing healthcare legislative and regulatory reform measures may have a material adverse effect on our business and results of operations

Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example, changes to our manufacturing arrangements; additions or
modifications to product labeling; the recall or discontinuation of our products; or additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the
operation  of  our  business.  If  we  are  slow  or  unable  to  adapt  to  changes  in  existing  requirements  or  the  adoption  of  new  requirements  or  policies,  or  if  we  are  not  able  to  maintain  regulatory
compliance,  we  may  lose  any  marketing  approval  that  we  may  have  obtained,  and  we  may  not  achieve  or  sustain  profitability.  See  the  section  entitled,  “Business  —  Government  Regulation  —
Healthcare Reform”.

Moreover, increasing efforts by governmental and third-party payors in the United States and abroad to cap or reduce healthcare costs may cause such organizations to limit both coverage and the
level  of  reimbursement  for  newly  approved  products  and,  as  a  result,  they  may  not  cover  or  provide  adequate  payment  for  our  product  candidates.  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 U.S. Congressional inquiries and proposed and enacted 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  the  state  level,  legislatures  are  increasingly  passing  legislation  and  implementing  regulations  designed  to  control  pharmaceutical  and  biologic  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. Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, financial condition, results of operations
and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be
included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our drugs or put pressure on our drug pricing, which could negatively affect our business,
financial condition, results of operations and prospects.

-30-

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 product candidates for which we may obtain regulatory approval or the frequency with which any such product candidate is prescribed or
used.  Additionally,  we  expect  to  experience  pricing  pressures  in  connection  with  the  sale  of  any  future  approved  product  candidates  due  to  the  trend  toward  managed  healthcare,  the  increasing
influence of health maintenance organizations, cost containment initiatives and additional legislative changes.

FT218, if successfully developed and approved, may cause undesirable side effects that limit the commercial profile or result in other significant negative consequences for approved products; or
delay or prevent further development or regulatory approval with respect to product candidates or new indications, or cause regulatory authorities to require labeling statements, such as boxed
warnings.

Undesirable  side  effects  caused  by  FT218,  if  successfully  developed  and  approved,  could  limit  the  commercial  profile  of  FT218  or  result  in  significant  negative  consequences  such  as  a  more
restrictive label or other limitations or restrictions. Undesirable side effects caused by FT218 could cause us or regulatory authorities to interrupt, delay or halt non-clinical studies and clinical trials or
could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities.

Clinical  trials  by  their  nature  utilize  a  sample  of  the  potential  patient  population.  With  a  limited  number  of  patients  and  limited  duration  of  exposure,  certain  side  effects  of  FT218  may  only  be
uncovered with a significantly larger number of patients exposed to the drug, and those side effects could be serious or life-threatening. If we or others identify undesirable side effects caused by
FT218 (or any other similar drugs), a number of potentially significant negative consequences could result, including:

•
•

regulatory authorities may withdraw or limit their marketing approval of such drugs;
regulatory authorities may require the addition of labeling statements, such as a “boxed” warning or additions to an existing boxed warning, or a contraindication, including as a result of
inclusion in a class of drugs for a particular disease;
regulatory authorities may refuse to approve label expansions for additional indications for any approved drugs;

regulatory authorities may require a modification of an existing REMS to mitigate risks;

•
• we may be required to change the way such drugs are distributed or administered, conduct additional clinical trials or change the labeling of the drugs;
•
• we may be subject to regulatory investigations and government enforcement actions;
• we may decide to remove FT218 from the marketplace;
• we could be sued and held liable for injury caused to individuals exposed to or taking FT218; and
•

our reputation may suffer.

Any of these events could prevent us from achieving or maintaining market acceptance of FT218, if approved, and could substantially increase the costs of commercializing FT218 and significantly
impact our ability to successfully commercialize FT218 and generate revenues.

We may incur significant liability if governmental authorities allege or determine that we are engaging in commercial activities or promoting FT218 in a way that violates applicable regulations.

Physicians  have  the  discretion  to  prescribe  drug  products  for  uses  that  are  not  described  in  the  product’s  labeling  and  that  differ  from  those  approved  by  the  FDA  or  other  applicable  regulatory
agencies. Off-label uses are common across medical specialties. Although the FDA and other regulatory agencies do not regulate a physician’s choice of treatments, the FDA and other regulatory
agencies regulate a manufacturer’s communications regarding off-label use and prohibit off-label promotion, as well as the dissemination of false or misleading labeling or promotional materials.
Manufacturers may not promote drugs for off-label uses. Accordingly, if FT218 is approved, we may not promote FT218 in the U.S. for any indications other than its FDA-approved indication. The
FDA and other regulatory and enforcement authorities actively enforce laws and regulations prohibiting promotion of off-label uses and the promotion of products for which marketing approval has
not been obtained. A company that is found to have improperly promoted off-label uses, including promoting unapproved dosing regimens, may be subject to significant liability, which may include
civil and administrative remedies as well as criminal sanctions.

Notwithstanding regulations related to product promotion, the FDA and other regulatory authorities allow companies to engage in truthful, non-misleading, and non-promotional scientific exchange
concerning their products. We currently, and intend to

-31-

increasingly, engage in medical education activities and communicate with healthcare providers in compliance with all applicable laws and regulatory guidance.

Obtaining and maintaining regulatory approval of FT218 in one jurisdiction does not mean that we will be successful in obtaining regulatory approval of FT218 in other jurisdictions.

Obtaining and maintaining regulatory approval of FT218 in one jurisdiction does not guarantee that we will be able to obtain or maintain regulatory approval in any other jurisdiction, while a failure
or delay in obtaining regulatory approval in one jurisdiction may have a negative effect on the regulatory approval process in others. For example, even if the FDA grants marketing approval of
FT218,  comparable  regulatory  authorities  in  foreign  jurisdictions  must  also  approve  FT218  in  those  countries.  Approval  procedures  vary  among  jurisdictions  and  can  involve  requirements  and
administrative review periods different from, and greater than, those in the U.S., including additional preclinical studies or clinical trials, as clinical trials conducted in one jurisdiction may not be
accepted by regulatory authorities in other jurisdictions. In many jurisdictions outside the U.S., a product candidate must be approved for reimbursement before it can be approved for sale in that
jurisdiction. In some cases, the price that we intend to charge for our products is also subject to approval. Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements
could  result  in  significant  delays,  difficulties  and  costs  for  us  and  could  delay  or  prevent  the  introduction  of  FT218  in  certain  countries.  If  we  fail  to  comply  with  the  regulatory  requirements  in
international markets or receive applicable marketing approvals, our market will be reduced and our ability to realize the full market potential of FT218 will be harmed.

Laws and regulations governing international operations we have and may expand in the future may preclude us from developing, manufacturing, and selling certain product candidates and
products outside of the U.S. and require us to develop and implement costly compliance programs.

As we seek to expand our operations outside of the U.S., we must dedicate additional resources to comply with numerous laws and regulations in each jurisdiction in which we plan to operate. The
Foreign Corrupt Practices Act (FCPA) prohibits any U.S. individual or business from paying, offering, authorizing payment, or offering anything of value, directly or indirectly, to any foreign official,
political  party,  or  candidate  for  the  purpose  of  influencing  any  act  or  decision  of  such  third  party  in  order  to  assist  the  individual  or  business  in  obtaining  or  retaining  business.  The  FCPA  also
obligates companies whose securities are listed in the U.S. to comply with certain accounting provisions requiring the company to maintain books and records that accurately and fairly reflect all
transactions of the company, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations.

Compliance with the FCPA is expensive and difficult, particularly in countries in which corruption is a recognized problem. 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. Similar laws in other countries, such as the U.K.
Bribery Act 2010, may apply to our operations.

Various laws, regulations, and executive orders also restrict the use and dissemination outside of the U.S., or the sharing with certain non-U.S. 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 of the U.S. in key European markets, we must dedicate additional resources to
comply with these laws, and such laws may preclude us from developing, manufacturing, or selling certain product candidates and products outside of the U.S., which could limit our growth potential
and increase our development costs.

The failure to comply with laws governing international business practices may result in substantial civil and criminal penalties and suspension or debarment from government contracting. The SEC
also may suspend or bar issuers from trading securities on U.S. exchanges for violations of the FCPA's accounting provisions.

Governments outside of the U.S. tend to impose strict price controls, which may adversely affect our revenues, if any.

In  some  countries,  particularly  the  countries  of  Europe,  the  pricing  of  prescription  pharmaceuticals  is  subject  to  governmental  control.  In  these  countries,  pricing  negotiations  with  governmental
authorities can take considerable time after the receipt of marketing authorization 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 candidate to other available therapies. If we seek approval for our lead product candidate or future product candidates outside of the
U.S. and reimbursement of our lead product

-32-

candidate or future product candidates is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be harmed.

Failure to comply with domestic and international privacy and security laws could result in the imposition of significant civil and criminal penalties.

The costs of compliance with privacy and security laws, including protecting electronically stored information from cyber-attacks, and potential liability associated with any compliance failures could
adversely affect our business, financial condition and results of operations. We are subject to various domestic and international privacy and security regulations, including but not limited to HIPAA
and  the  General  Data  Protection  Regulation  (“GDPR”),  (Regulation  EU  2016/679).  HIPAA  mandates,  among  other  things,  the  adoption  of  uniform  standards  for  the  electronic  exchange  of
information in common healthcare transactions, as well as standards relating to the privacy and security of individually identifiable health information, which require the adoption of administrative,
physical and technical safeguards to protect such information. In addition, many U.S. states have enacted comparable laws addressing the privacy and security of health information, some of which
are more stringent than HIPAA. GDPR requires Avadel to ensure personal data collected by Avadel is gathered legally and under strict conditions and to protect such personal data from misuse and
exploitation. If Avadel fails to comply with HIPAA, GDPR or other similar laws, we will face significant fines and penalties that could adversely affect our business, financial condition and results of
operations.

Risks Related to Our Financial Position and Capital Requirements

We incurred a net loss in 2021 and we will likely incur a net loss in 2022, and if we are not able to regain profitability in the future, the value of our shares may fall.

Although we reported a net income for the year ended December 31, 2020 due to the gain on the sale of our Hospital Products, we incurred a net loss of $77,329 for the year ended December 31,
2021. We do not expect to become profitable in the near future, and may never achieve profitability. The amount of our future net losses will depend, in part, on the rate of our future expenditures and
our ability to recognize revenues from the commercialization of FT218, if approved. We have devoted significant financial resources to research and development, including our clinical development
activities, and the pursuit of regulatory approval for FT218. If we obtain marketing approval, our future revenues will depend upon the size of any markets in which FT218 and any future products
have received approval, and our ability to achieve sufficient market acceptance, reimbursement from third-party payors and adequate market share for our product and any future products in those
markets. In addition, we are in the process of building a sales organization and supporting commercial infrastructure and, accordingly, we will incur significant expenses as we continue to develop a
sales organization and commercial infrastructure in advance of generating any commercial product sales. Because of the numerous risks and uncertainties associated with developing pharmaceutical
products, we are unable to predict the extent of any future losses or when we will become profitable, if at all. Our ability to operate profitably depends upon a number of factors, many of which are
beyond our direct control. These factors include:

•
•
•
•
•
•
•
•
•
•
•

the timely receipt of necessary approvals from the FDA for the commercialization of FT218;
our ability to obtain, build and expand manufacturing capacity, including capacity at third-party manufacturers;
the effectiveness of our sales and marketing strategy;
the demand and market size for FT218;
the level of product and price competition for FT218;
our ability to develop new partnerships and additional commercial applications for FT218 and any future product candidates;
our ability to control our costs;
the initiation of additional research, preclinical, clinical or other programs as we seek to identify and validate additional product candidates;
our ability to acquire or in-license other product candidates and technologies;
our ability to maintain, protect and expand our intellectual property portfolio;
general economic conditions.

Even if the FDA approves our NDA for FT218, we may never recognize revenue in amounts sufficient to achieve and maintain profitability. The net losses we incur may fluctuate significantly from
quarter to quarter and year to year, such that a period-to-period comparison of our results of operations may not be a good indication of our future performance. In any particular quarter or quarters,
our operating results could be below the expectations of securities analysts or investors, which could cause our stock price to decline.

-33-

We may require additional financing, which may not be available on favorable terms or at all, and which may result in dilution of the equity interest of the holders of ADSs.

We may require additional financing to fund the development and possible acquisition of new products and businesses. We may consume available resources more rapidly than currently anticipated,
resulting in the need for additional funding. Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and
commercialize  FT218,  if  approved.  If  we  cannot  obtain  financing  when  needed,  or  obtain  it  on  favorable  terms,  we  may  be  required  to  curtail  our  plans  to  continue  to  develop  drug  delivery
technologies, develop new products, or acquire additional products and businesses. Other factors that will affect future capital requirements and may require us to seek additional financing include:

•
•
•

the development and acquisition of new products and drug delivery technologies;
the progress of our research and product development programs; and
the timing of, and amounts received from, future product sales, product development fees and licensing revenue and royalties.

If  adequate  funds  are  not  available,  we  may  be  required  to  significantly  reduce  or  refocus  our  product  development  efforts,  resulting  in  loss  of  sales,  increased  costs  and  reduced  revenues.
Alternatively, to obtain needed funds for acquisitions or operations, we may seek to issue additional ADSs representing our ordinary shares, or issue equity-linked debt, or we may choose to issue
preferred shares, in either case through public or private financings. Additional funds may not be available on terms that are favorable to us and, in the case of such equity financings, may result in
dilution  to  the  holders  of  ADSs.  We  could  also  be  required  to  seek  funds  through  arrangements  with  collaborative  partners  and  we  may  be  required  to  relinquish  rights  to  some  of  our  product
candidates or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, operating results and prospects.

Our net loss and use of cash in operating activities may limit our ability to fully pursue our business strategy.

We reported net loss of $77,329 in 2021. We reported cash used in operating activities of $77,310. Cash and marketable securities as of December 31, 2021 totaled $157,221. Our business strategy is
to primarily focus on the development and potential FDA approval of FT218 for the treatment of EDS or cataplexy in adults with narcolepsy. The successful pursuit of all components of our strategy
will require substantial financial resources, and there can be no assurance that our existing cash and marketable securities assets and the cash generated by our operations will be adequate for these
purposes. We will likely incur a net loss in 2022 and, if we use existing cash and marketable securities, there is no guarantee that we would be able to generate additional cash through our operations
or through financing. Failure to implement any component of our strategy may prevent us from achieving profitability in the future or may otherwise have a material adverse effect on our financial
condition and results of operation.

Risks Related to Regulation

The  distribution  and  sale  of  FT218,  if  approved,  will  be  subject  to  significant  regulatory  restrictions,  including  the  requirements  of  a  REMS  and  safety  reporting  requirements,  and  these
regulatory requirements will subject us to risks and uncertainties, any of which could negatively impact sales of FT218, if approved.

The active pharmaceutical ingredient, or API, of FT218 is a form of gamma-hydroxybutyric acid, or GHB, a central nervous system depressant known to be associated with facilitated sexual assault
as well as with respiratory depression and other serious side effects. As a result, the FDA requires that sponsors of sodium oxybate products, such as FT218, if approved, maintain a REMS to help
ensure that the benefits of the drug in treatment of EDS or cataplexy in adults with narcolepsy outweigh the serious risks of the drug. A REMS imposed on FT218, if approved, may impose extensive
controls  and  restrictions  on  the  sales  and  marketing  of  FT218  that  we  will  be  responsible  for  implementing.  Any  failure  to  demonstrate  our  substantial  compliance  with  any  REMS  obligations,
including as a result of business or other interruptions resulting from the evolving effects of the COVID-19 pandemic, or a determination by the FDA that the REMS is not meeting its goals, could
result in enforcement action by the FDA, lead to changes in our REMS obligations, negatively affect sales of FT218, result in additional costs and expenses for us or require us to invest a significant
amount of resources, any of which could materially and adversely affect our business, financial condition, results of operations and growth prospects.

We cannot predict whether the FDA will request, seek to require or ultimately require modifications to, or impose additional requirements on, the REMS for FT218, if approved. Any modifications
approved, required or rejected by the FDA could change the safety profile of FT218, and have a significant negative impact in terms of product liability, public acceptance of FT218 for treatment of
cataplexy or EDS in adults with narcolepsy, and prescribers’ willingness to prescribe, and patients’

-34-

willingness to take, FT218, any of which could have a material adverse effect on our business. Modifications approved, required or rejected by the FDA could also make it more difficult or expensive
for us to distribute FT218, make distribution easier for sodium oxybate competitors, disrupt continuity of care for FT218 patients or negatively affect sales of FT218.

Pharmaceutical companies, including their agents and employees, are required to monitor adverse events occurring during the use of their products and report them to the FDA. As required by the
FDA, and similarly for other regulatory agencies, the adverse event information that we collect for FT218, if approved, must be regularly reported to the FDA and could result in the FDA requiring
changes to FT218’s labeling, including additional warnings or boxed warnings, or requiring us to take other actions that could have an adverse effect on patient and prescriber acceptance of FT218.

Any  failure  to  demonstrate  our  substantial  compliance  with  a  REMS  required  for  FT218,  if  approved,  or  any  other  applicable  regulatory  requirements  to  the  satisfaction  of  the  FDA  or  another
regulatory authority could result in such regulatory authorities taking actions in the future which could have a material adverse effect on sodium oxybate product sales and therefore on our business,
financial condition, results of operations and growth prospects.

Disruptions at the FDA, the DEA 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 to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept
the payment of user fees, and statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result. 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.

Disruptions  at  the  FDA,  DEA  and  other  agencies  may  also  increase  the  time  necessary  for  new  product  candidates  to  be  reviewed  or  approved  by  necessary  government  agencies,  which  would
adversely affect our business. For example, over the last several years the U.S. 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, 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,  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.

As of May 26, 2021, the FDA noted it was continuing to ensure timely reviews of applications for medical products during the ongoing COVID-19 pandemic in line with its user fee performance
goals and conducting mission critical U.S. and non-U.S. inspections to ensure compliance of manufacturing facilities with FDA quality standards. However, the FDA may not be able to maintain its
current pace and approval timelines could be extended due to the ongoing COVID-19 pandemic. Since March 2020 when foreign and domestic inspections of facilities were largely placed on hold,
the FDA has been working to resume routine surveillance, bioresearch monitoring and pre-approval inspections on a prioritized basis. Since April 2021, the FDA has conducted limited inspections
and employed remote interactive evaluations, using risk management methods, to meet user fee commitments and goal dates. Ongoing travel restrictions and other uncertainties continue to impact
oversight operations both domestic and abroad and it is unclear when standard operational levels will resume. The FDA is continuing to complete mission-critical work, prioritize other higher-tiered
inspectional  needs  (e.g.,  for-cause  inspections),  and  carry  out  surveillance  inspections  using  risk-based  approaches  for  evaluating  public  health.  Should  the  FDA  determine  that  an  inspection  is
necessary for approval and an inspection cannot be completed during the review cycle due to restrictions on travel, and the FDA does not determine a remote interactive evaluation to be adequate, the
FDA  has  stated  that  it  generally  intends  to  issue,  depending  on  the  circumstances,  or  defer  action  on  the  application  until  an  inspection  can  be  completed.  During  the  COVID-19  public  health
emergency, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. Regulatory authorities outside the
U.S. may adopt similar restrictions or other policy measures in response to the COVID-19 pandemic and may experience delays in their regulatory activities. We cannot guarantee that the FDA, DEA
and other agencies, as applicable, will be able to complete any required inspections or take other necessary actions in respect to our product candidate or future product candidates.

FT218, if approved by the FDA, may not obtain desired regulatory exclusivities, including orphan drug exclusivity.

Under the Orphan Drug Act, as amended, the FDA may designate a drug as an orphan drug if it is intended to treat a rare disease or condition, which is defined as a patient population of fewer than
200,000 individuals in the U.S., or a patient

-35-

population of 200,000 or more where there is no reasonable expectation that the cost of developing the drug for the rare disease or condition will be recovered from sales of the drug in the U.S.
Generally, if a drug with orphan drug designation subsequently receives the first marketing approval for the disease or condition for which it has such designation, the drug is entitled to a period of
marketing exclusivity, which precludes the FDA from approving another marketing application for the same drug for the same disease or condition for seven years, except in limited circumstances,
such  as  if  the  FDA  concludes  that  a  subsequent  same  drug  is  clinically  superior  through  greater  safety,  greater  effectiveness,  or  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.

Although FT218 obtained orphan drug designation for the treatment of narcolepsy from the FDA in January 2018, there is no guarantee that we will obtain approval or orphan drug exclusivity for
FT218. Orphan drug designation does not give a product candidate any advantage in, or shorten the timeline for, the FDA regulatory review and approval process. In addition, because FT218 would
not be the first sodium oxybate product to be approved for the treatment of narcolepsy, we must demonstrate that FT218 is clinically superior to any previously approved same drug in order to obtain
orphan  drug  exclusivity  for  FT218,  and  we  may  be  required  to  demonstrate  clinical  superiority  for  the  approval  and  exclusivity  of  other  product  candidates  in  the  future.  However,  such  a
demonstration may be difficult to establish and there can be no assurance that we will be successful in these efforts. Even if we obtain orphan drug exclusivity for FT218, that exclusivity may not
effectively  protect  FT218  from  competition  because  different  drugs  can  be  approved  for  the  same  condition.  In  addition,  the  FDA  could  determine  that  unexpired  orphan  drug  exclusivity  for  an
approved product that is determined to be the same drug could delay the approval of FT218 unless we are able to demonstrate that FT218 is clinically superior to such approved product. Moreover,
any orphan drug exclusive marketing rights may be lost if the FDA later determines that the request for designation was materially defective or if we are unable to assure sufficient quantity of FT218
to meet the needs of patients with the particular rare disease or condition. The FDA may reevaluate its regulations and policies under the Orphan Drug Act. We do not know if, when or how the FDA
may change the orphan drug regulations and policies in the future, and it is uncertain how any changes might affect our business. Depending on what changes, the FDA may make to its orphan drug
regulations and policies, our business could be adversely impacted.

The API in FT218, sodium oxybate, is a controlled substance subject to U.S. federal and state controlled substance laws and regulations and applicable controlled substance legislation in other
countries, and our failure, or the failure of third-parties on whom we rely, to comply with these laws and regulations, or the cost of compliance with these laws and regulations, could materially
and adversely affect our business, results of operations, financial condition and growth prospects.

FT218 contains a controlled substance as defined in the CSA. Controlled substances are subject to a number of requirements and restrictions under the CSA and implementing regulations, including
certain  registration,  security,  recordkeeping,  reporting,  manufacturing  and  procurement  quotas,  import,  export  and  other  requirements  administered  by  the  DEA.  The  DEA  classifies  controlled
substances into five schedules: Schedule I, II, III, IV or V. Schedule I substances by definition have a high potential for abuse, no currently “accepted medical use” in the U.S., lack accepted safety for
use  under  medical  supervision,  and  may  not  be  prescribed,  marketed  or  sold  in  the  U.S.  Pharmaceutical  products  approved  for  use  in  the  U.S.  which  contain  a  controlled  substance  are  listed  as
Schedule II, III, IV or V, with Schedule II substances considered to present the highest potential for abuse or dependence and Schedule V substances the lowest relative risk of abuse among such
substances. Schedule I and II drugs are subject to the strictest controls under the CSA, including manufacturing and procurement quotas, heightened security requirements and additional criteria for
importation. The API of FT218, oxybate salts, are regulated by the DEA as Schedule I controlled substances, and FDA-approved products containing oxybate salts, including sodium oxybate, are
currently Schedule III.

Individual  states  have  also  established  controlled  substance  laws  and  regulations.  Although  state-controlled  substances  laws  often  mirror  federal  law,  they  may  separately  schedule  our  product
candidates. We or our partners may also be required to obtain separate state registrations, permits or licenses in order to be able to manufacture, research, distribute, import, export, administer or
prescribe controlled substances for clinical trials or commercial sale, and failure to meet applicable regulatory requirements could lead to enforcement and sanctions by the states in addition to those
from the DEA or otherwise arising under federal law.

U.S.  facilities  conducting  research,  manufacturing,  distributing,  importing  or  exporting,  or  dispensing  of  controlled  substances  must  be  registered  (licensed)  to  perform  these  activities  and  must
comply with the security, control, recordkeeping and reporting obligations under the CSA, DEA regulations and corresponding state requirements. DEA and state regulatory bodies conduct periodic
inspections of certain registered establishments that handle controlled substances. Obtaining and maintaining

-36-

the necessary registrations, obtaining and maintaining quotas and complying with the regulatory obligations may result in delay of the importation, export, manufacturing, distribution or research of
our lead product candidate and our commercial product, if approved, and any future products candidates or products. Furthermore, failure to maintain compliance with the CSA and DEA and state
regulations  by  us  or  any  of  our  contractors,  distributors  or  pharmacies  can  result  in  regulatory  action  that  could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of
operations. In addition, if we change any third-party upon whom we rely to conduct our research, manufacturing, distributing, importing, exporting, or dispensing activities, doing so will result in
additional costs and expenses and may take a significant amount of time, and we may be unsuccessful in identifying a new, satisfactory third-party, any of which could materially and adversely affect
our  business,  financial  condition,  and  results  of  operations.  DEA  and  state  regulatory  bodies  may  seek  civil  penalties,  refuse  to  renew  necessary  registrations,  or  initiate  proceedings  to  restrict,
suspend or revoke those registrations. In certain circumstances, violations could lead to criminal penalties.

Because FT218 contains sodium oxybate, to conduct clinical trials with FT218 in the U.S. prior to approval, each of our research sites must submit a research protocol to the DEA and obtain and
maintain a DEA researcher registration that allows those sites to handle and dispense FT218 and to obtain the product candidate. If the DEA delays or denies the grant of a researcher registration to
one or more research sites, the clinical trial could be significantly delayed, and we could lose clinical trial sites. In the event the product candidate would be made outside the U.S., the importer for the
clinical trials must also obtain a Schedule I importer registration and an import permit for each import.

We and our manufacturing partners in the U.S. are subject to the DEA’s annual manufacturing and procurement quota requirements. Additionally, even though FT218, if approved, will be classified
as Schedule III, the active ingredient in the final dosage form, sodium oxybate, is a Schedule I controlled substance and will continue be subject to such quotas as long as it remains classified as
Schedule  I.  The  annual  quota  allocated  to  us  or  our  U.S.  manufacturing  partners  for  sodium  oxybate  may  not  be  sufficient  to  complete  clinical  trials  or  meet  commercial  demand  of  FT218,  if
approved. Consequently, any delay or refusal by the DEA in establishing our, or U.S. manufacturing partner’s, procurement and/or production quota for controlled substances could delay or stop our
clinical trials or commercial activities, if approved, which could have a material adverse effect on our business, financial position and results of operations.

If approved, FT218 will be classified as a Schedule III substance and an importer can import it for commercial purposes if it obtains the appropriate registrations and licenses from the DEA, including
an importer registration and files an application for an import permit for each import. The DEA provides annual assessments/estimates to the International Narcotics Control Board, which guides the
DEA in the amounts of controlled substances that the DEA authorizes to be imported. To the extent an importer is utilized for commercial purposes, failure by any current importer or future importer
that we identify as an importer, if any are available, to obtain and maintain the necessary import authority from the DEA and other applicable regulatory authorities, including specific quantities,
could affect the availability of FT218 and have a material adverse effect on our business, results of operations and financial condition.

Governments outside of the U.S. have similar controlled substance laws, regulations and requirements in their respective jurisdictions, and our failure, or the failure of third parties upon whom we
rely, to comply with applicable controlled substance laws, regulations and requirements or secure necessary authorizations would result in similar risks to those described above.

We will need to obtain FDA approval of any proposed product names, and any failure or delay associated with such approval may adversely impact our business.

Any name we intend to use for our product candidates will require approval from the FDA regardless of whether we have secured a trademark registration from the USPTO. The FDA typically
conducts a review of proposed product names, including an evaluation of potential for confusion with other product names. The FDA may object to any product name we submit if it believes the
name inappropriately implies medical claims. If the FDA objects to any of our proposed product names, we may be required to adopt an alternative name for our product candidates. If we adopt an
alternative name, we would lose the benefit of any existing trademark applications for such product candidate and may be required to expend significant additional resources in an effort to identify a
suitable product name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA. We may be unable to build a successful brand
identity for a new trademark in a timely manner or at all, which would limit our ability to commercialize our product candidates.

Risks Related to our Reliance on Third-Parties

We rely, and intend to continue to rely on single source providers for the development, manufacture and supply of FT218, and if we experience problems with these suppliers, or they fail to
comply with applicable regulatory requirements or to

-37-

supply sufficient quantities at acceptable quality levels or prices, or at all, our business would be materially and adversely affected.

Currently,  we  use  single  source  providers  for  the  development,  supply  of  clinical  materials  and  supply  of  commercial  batches  for  our  lead  product  candidate,  FT218.  We  do  not  own  or  operate
manufacturing  facilities  for  clinical  or  commercial  manufacture  of  FT218.  We  have  limited  personnel  with  experience  in  drug  manufacturing  and  we  lack  the  capabilities  to  manufacture  FT218
clinical or commercial scale. There can be no assurance that our clinical development or commercial product supplies will not be limited, interrupted, or of satisfactory quality or continue to be
available at acceptable quantities or prices to meet commercial demand, if FT218 is approved. If the supplies of these products or materials were interrupted for any reason, including but not limited
to, natural disasters, labor or civil unrest, global health concerns or pandemics or acts of war or terrorism, delays at the manufacturer, delays related to quality control, delays related to the supply
chain and the manufacturing and supply of certain products could be delayed. If the supplies of these products or materials were interrupted for any reason, our manufacturing, clinical development or
commercial activities, if approved, of FT218 could be delayed. These delays could be extensive and expensive, especially in situations where a substitution was not readily available or required
variations of existing regulatory approvals and certifications or additional regulatory approval For example, an alternative supplier may be required to pass an inspection by the FDA, EMA or the
competent  authorities  of  EU  Member  States  for  compliance  with  current  cGMP  requirements  before  supplying  us  with  product  or  before  we  may  incorporate  that  supplier’s  ingredients  into  the
manufacturing of FT218 by our contract development and manufacturing organizations (“CDMOs”).

Additionally, our third-party suppliers may not be required to, or may be unable to, provide us with any guaranteed minimum production levels or have sufficient dedicated capacity for our drug.
Failure to obtain adequate supplies in a timely manner could have a material adverse effect on our business, financial condition and results of operations.

We contract with third parties for the manufacture of FT218 for clinical testing and expect to continue to do so throughout commercialization. This reliance on third parties increases the risk
that  we  will  not  have  sufficient  quantities  of  our  product  candidate  or  product  or  such  quantities  at  an  acceptable  cost,  which  could  delay,  prevent  or  impair  our  development  or
commercialization efforts.

We do not currently own or operate, nor do we have any plans to establish in the future, any manufacturing facilities. We rely, and expect to continue to rely, on third parties for the manufacture of
FT218 for clinical testing, as well as for the commercial manufacture of our product if FT218 receives marketing approval. This reliance on third parties increases the risk that we will not have
sufficient quantities of our product candidate or product or such quantities at an acceptable cost or quality, which could delay, prevent or impair our development or commercialization efforts.

The facilities used by CDMOs generally must be inspected by the FDA pursuant to pre-approval inspections conducted as a part of the FDA’s review of an NDA. We do not control the manufacturing
process  of,  and  will  be  completely  dependent  on,  our  CDMOs  for  compliance  with  cGMPs  in  connection  with  the  manufacture  of  our  product  candidate.  If  our  CDMOs  cannot  successfully
manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or others, they will not be able to pass regulatory inspections and/or maintain regulatory
compliance for their manufacturing facilities. In addition, we have no control over the ability of our CDMOs to maintain adequate quality control, quality assurance and qualified personnel. If the
FDA or a comparable foreign regulatory authority finds deficiencies with or does not approve these facilities for the manufacture of our product candidate or if it finds deficiencies or withdraws any
such approval in the future, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our product
candidate, if approved.

CDMOs  upon  whom  we  rely  are  also  required  to  comply  with  the  CSA,  DEA  regulations  and  other  applicable  controlled  substance  laws,  regulations  and  requirements  in  other  countries,  where
applicable, including and those relating to licensing and registration requirements. The inability of our CDMOs to maintain compliance with applicable controlled substance laws, regulations and
requirements and obtain and maintain the necessary licenses and registrations could have a material adverse effect on our business, including our clinical trials, commercial activities, if approved,
financial position and results of operations.

If any CDMO with whom we contract fails to perform its obligations, we may be forced to enter into an agreement with a different CDMO, which we may not be able to do on reasonable terms, if at
all. In such scenario, our clinical trials or commercial supply could be delayed significantly as we establish alternative supply sources. In some cases, the technical skills required to manufacture our
product candidate or product, if approved, may be unique or proprietary to the original CDMO 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 CDMOs for any

-38-

reason,  we  will  be  required  to  verify  that  the  new  CDMO  maintains  facilities  and  procedures  that  comply  with  quality  standards  and  with  all  applicable  regulations,  including  those  relating  to
controlled substances. We will also need to verify, such as through a manufacturing comparability study, that any new manufacturing process will produce our product candidate or 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 CDMO could negatively affect our ability to
develop FT218 or commercialize our product, if approved, in a timely manner or within budget. Furthermore, a CDMO may possess technology related to the manufacture of our product candidate or
product that such CDMO owns independently. This would increase our reliance on such CDMO or require us to obtain a license from such CDMO in order to have another CDMO manufacture our
product candidate or product. In addition, in the case of CDMOs that supply our product candidate, 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.

Further, 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 product candidates or products, if approved, operating restrictions and criminal prosecutions,
any of which could significantly and adversely affect our business and supplies of our product candidates.

We may be unable to establish any agreements with third-party manufacturers or to do so on acceptable terms. Even if we are able to establish agreements with third-party manufacturers, reliance on
third-party manufacturers entails additional risks, including:

•
•
•
•

reliance on the third party for regulatory compliance and quality assurance;
the possible breach of the manufacturing agreement by the third party;
the possible misappropriation of our proprietary information, including our trade secrets and know-how; and
the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us.

Our product candidates and any products that we may develop may compete with other product candidates and approved products for access to manufacturing facilities. There are a limited number of
manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us. Any performance failure on the part of our existing or future manufacturers could delay clinical
development or marketing approval. If our current CDMOs cannot perform as agreed, we may be required to replace such manufacturers. We may incur added costs and delays in identifying and
qualifying any such replacement. Our current and anticipated future dependence upon others for the manufacture of our product candidates or products may adversely affect our future profit margins
and our ability to commercialize any products that receive marketing approval on a timely and competitive basis.

We outsource important activities to consultants, advisors and outside contractors.

We outsource many key functions of our business and therefore rely on a substantial number of consultants, advisors and outside contractors. If we are unable to effectively manage our outsourced
activities or if the quality or accuracy of the services provided by such third parties is compromised for any reason, our development activities may be extended, delayed or terminated which would
have an adverse effect on our development program and our business.

We depend on key personnel to execute our business plan. If we cannot attract and retain key personnel, we may not be able to successfully implement our business plan.

We are highly dependent on the expertise of Gregory Divis, our Chief Executive Officer, Thomas S. McHugh, our Chief Financial Officer, and Richard Kim, our Chief Commercial Officer, as well as
the other key members of our management, scientific, clinical and commercial team. Although we have entered into employment letter agreements with our executive officers, each of them may
terminate their employment with us at any time. We do not maintain “key person” insurance for any of our executives or other employees.

Recruiting and retaining qualified scientific, clinical, manufacturing and sales and marketing personnel will also be critical to our success. The loss of the services of our executive officers or other
key  employees  could  impede  the  achievement  of  our  research,  development  and  commercialization  objectives  and  seriously  harm  our  ability  to  successfully  implement  our  business  strategy.
Furthermore, replacing executive officers and 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

-39-

successfully develop, gain regulatory approval of and commercialize drugs. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key
personnel 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. Failure to obtain FDA approval for FT218 may make it more challenging to recruit and retain qualified personnel.

We will need to expand our organization and we may experience difficulties in managing this growth, which could disrupt our operations.

We currently employ approximately 66 full-time employees. As we mature and commercialize FT218, if approved, we expect to expand our full-time employee base. Our management may need to
divert a disproportionate amount of its attention away from our day-to-day activities and devote a substantial amount of time to managing these growth activities. We may not be able to effectively
manage the expansion of our operations, which may result in weaknesses in our infrastructure, operational mistakes, loss of business opportunities, loss of employees and reduced productivity among
remaining  employees.  Our  expected  growth  could  require  significant  capital  expenditures  and  may  divert  financial  resources  from  other  projects,  such  as  the  development  of  additional  product
candidates. If our management is unable to effectively manage our growth, our expenses may increase more than expected, our ability to recognize and/or grow revenues could be reduced and we
may not be able to implement our business strategy. Our future financial performance and our ability to commercialize FT218 and compete effectively will depend, in part, on our ability to effectively
manage any future growth.

We rely on third parties to conduct our clinical trials, and if they do not properly and successfully perform their contractual, legal and regulatory duties, we may not be able to obtain regulatory
approvals for or commercialize FT218 and future product candidates.

We rely on CROs and other third parties to assist us in designing, managing, monitoring and otherwise carrying out our clinical trials, including with respect to site selection, contract negotiation and
data management. We do not control these third parties and, as a result, they may not treat our clinical studies as a high priority, which could result in delays. We are responsible for confirming that
each of our clinical trials is conducted in accordance with its general investigational plan and protocol, as well as the FDA’s and foreign regulatory agencies’ requirements, commonly referred to as
good clinical practices, for conducting, recording and reporting the results of clinical trials to ensure that the data and results are credible and accurate and that the trial participants are adequately
protected. The FDA and foreign. regulatory agencies enforce good clinical practices through periodic inspections of trial sponsors, principal investigators and trial sites. If we, CROs or other third
parties assisting us or our study sites fail to comply with applicable good clinical practices, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or its non-U.S.
counterparts may require us to perform additional clinical trials before approving our marketing applications. We cannot assure you that, upon inspection, the FDA or foreign regulatory agencies will
determine that any of our clinical trials comply with good clinical practices.

If third parties do not successfully carry out their duties under their agreements with us, if the quality or accuracy of the data they obtain is compromised due to failure to adhere to our clinical
protocols,  including  dosing  requirements,  or  regulatory  requirements,  or  if  they  otherwise  fail  to  comply  with  clinical  trial  protocols  or  meet  expected  deadlines,  our  clinical  trials  may  not  meet
regulatory requirements. If our clinical trials do not meet regulatory requirements or if these third parties need to be replaced, our clinical trials may be extended, delayed, suspended or terminated. If
any of these events occur, we may not be able to obtain regulatory approval of our product candidate and future product candidates or succeed in our efforts to create approved line extensions for
certain of our existing products or generate additional useful clinical data in support of these products.

-40-

If we or our partners fail to comply with these laws and regulations, the FDA, or other foreign regulatory agencies, may take actions that could significantly restrict or prohibit commercial distribution
of FT218. If the FDA or other foreign regulatory authorities determine that we are not in compliance with these laws and regulations, they could, among other things:

issue warning letters;
impose fines;
seize products or request or order recalls;
issue injunctions to stop future sales of products;
refuse to permit products to be imported into, or exported out of a particular country;
suspend or limit our production;

•
•
•
•
•
•
• withdraw or vary approval of marketing applications;
 withdraw approval of marketing applications; and
•
initiate criminal prosecutions.
•

We may rely on collaborations with third parties to commercialize FT218 outside of the U.S., if approved, and certain of our future product candidates and such strategy involves risks that could
impair our prospects for realizing profits from such products.

We expect that the commercialization of FT218 outside of the U.S., if approved, or future product candidates may require collaboration with third-party partners involving strategic alliances, licenses,
product divestitures or other arrangements. We may not be successful in entering into such collaborations on favorable terms, if at all, or our collaboration partners may not adequately perform under
such arrangements, and as a result our ability to commercialize these products will be negatively affected and our prospects will be impaired.

We  face  significant  competition  in  seeking  appropriate  collaborators.  Whether  we  reach  a  definitive  agreement  for  a  collaboration  will  depend,  among  other  things,  upon  our  assessment  of  the
collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s own evaluation of a potential collaboration. Such factors a potential
collaborator will use to evaluate a collaboration may include the design or results of clinical trials, the likelihood of approval by the FDA or comparable foreign regulatory authorities, the potential
market for FT218 or future product candidates, the potential of competing products, the existence of uncertainty with respect to our ownership of our intellectual property, which can exist if there is a
challenge  to  such  ownership  without  regard  to  the  merits  of  the  challenge  and  industry  and  market  conditions  generally.  The  collaborator  may  also  consider  alternative  product  candidates  or
technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for FT218. The terms of any additional
collaborations or other arrangements that we may establish may not be favorable to us.

We  may  also  be  restricted  under  collaboration  agreements  from  entering  into  future  agreements  on  certain  terms  with  potential  collaborators.  Collaborations  are  complex  and  time-consuming  to
negotiate and document. In addition, there have been a significant number of recent business combinations among large pharmaceutical companies that have resulted in a reduced number of potential
future collaborators.

We may not be able to negotiate additional collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of our product candidates
for  which  we  are  seeking  to  collaborate,  reduce  or  delay  its  development  program,  delay  its  potential  commercialization  or  reduce  the  scope  of  any  sales  or  marketing  activities,  or  increase  our
expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own,
we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop FT218 outside of the
U.S., if approved, or future product candidates, or bring these products to market and generate product revenue.

In addition, any future collaborations that we enter into may not be successful. The success of our collaboration arrangements will depend heavily on the efforts and activities of our collaborators.
Collaborators generally have significant discretion in determining the efforts and resources that they will apply to these collaborations. Disagreements between parties to a collaboration arrangement
regarding clinical development and commercialization matters can lead to delays in the development process or commercializing the applicable product candidate and, in some cases, termination of
the  collaboration  arrangement.  These  disagreements  can  be  difficult  to  resolve  if  neither  of  the  parties  has  final  decision-making  authority.  Collaborations  with  pharmaceutical  or  biotechnology
companies and other third parties often are terminated or allowed to expire by the other party. Any such termination or expiration would adversely affect us financially and could harm our business
reputation.

Risks Related to Our Intellectual Property

If we cannot adequately protect our intellectual property and proprietary information, we may be unable to effectively compete.

Our success depends, in part, on our ability to obtain and enforce patents and other intellectual property rights for our product candidate and future product candidates and technology, including our
drug delivery technologies, and to preserve our trade secrets and other proprietary information. If we cannot do so, our competitors may exploit our technologies and deprive us of the ability to realize
revenues and profits from our product candidate and future product candidates and technologies.

To the extent any of our product candidate and future product candidates may benefit from protections afforded by patents, we face the risk that patent law relating to the scope of claims in the
pharmaceutical and biotechnology fields is continually evolving and can be the subject of uncertainty and may change in a way that would limit protection. If challenged, a court or other body may
determine that our patents may not be exclusive, valid or enforceable. For example, our patents may not protect us against challenges by companies that submit drug marketing applications to the
FDA, or the competent authorities of EU Member States or other jurisdictions in which we may attempt to compete, in particular where such applications rely, at least in part, on safety and efficacy
data from our product candidate and future product candidates. In addition, competitors may obtain patents that may have an adverse effect on our ability to conduct business, or they may discover
ways to circumvent our patents. The scope of any patent protection may not be sufficiently broad to cover our product candidate and future product candidates or to exclude competing products. Any
patent applications we have made or may make relating to our potential products or technologies may not result in patents being issued. Even after issuance, our patents may be challenged in the
courts or patent offices in the U.S. and elsewhere. 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 stop others from using or commercializing similar or identical product candidates, or limit the duration of the patent protection of our product candidate and future product
candidates. Further, patent protection once obtained is limited in time, after which competitors may use the covered product or technology without obtaining a license from us. Because of the time
required to obtain regulatory marketing approval, the remaining period of effective patent protection for a marketed product is frequently substantially shorter than the full duration of the patent.
While a patent term extension can be requested under certain circumstances, the grant of such a request is not guaranteed.

Our partnerships with third parties expose us to risks that they will claim intellectual property rights on our inventions or fail to keep our unpatented products or technology confidential.

If we are unable to protect the confidentiality of our trade secrets, the value of our technology could be materially adversely affected and our business would be harmed.

We also rely on trademarks, copyrights, trade secrets and know-how to develop, maintain and strengthen our competitive position.

To protect our product candidate, trade secrets and proprietary technologies, we rely, in part, on confidentiality agreements with our employees, suppliers, consultants, advisors and partners. These
agreements  may  not  provide  adequate  protection  for  our  trade  secrets  and  other  proprietary  information  in  the  event  of  any  unauthorized  use  or  disclosure,  or  if  others  lawfully  develop  the
information. If these agreements are breached, we cannot be certain we will have adequate remedies. Further, we cannot guarantee that third parties will not know, discover or independently develop
equivalent proprietary information or technologies, or that they will not gain access to our trade secrets or disclose our trade secrets to the public. Therefore, we cannot guarantee we can maintain and
protect unpatented proprietary information and trade secrets. Misappropriation or other loss of our intellectual property would adversely affect our competitive position and may cause us to incur
substantial litigation or other costs.

If we and our partners do not adequately protect the trademarks and trade names for our products, then we and our partners may not be able to build name recognition in our markets of interest
and our business may be adversely affected.

Our competitors or other third parties may challenge, infringe or circumvent the trademarks or trade names for our products. We and our partners may not be able to protect these trademarks and trade
names. In addition, if the trademarks or trade names for one of our products infringe the rights of others, we or our partners may be forced to stop using the trademarks or trade names, which we need
for name recognition in our markets of interest. If we cannot establish name recognition based on our trademarks and trade names, we and our partners may not be able to compete effectively and our
business may be adversely affected.

-42-

Changes in U.S. or ex-U.S. patent laws could diminish the value of patents in general, thereby impairing our ability to protect our product candidate and future product candidates.

Changes in either the patent laws or interpretation thereof in the U.S. or in ex-U.S. jurisdictions could increase uncertainties and costs surrounding the prosecution of patent applications and the
enforcement or defense of issued patents. For example, the Leahy-Smith America Invents Act of 2011 (“AIA”), changed the previous U.S. “first-to-invent” system to the current system that awards a
patent to the “first-inventor-to-file” for an application for a patentable invention. This change alters the pool of available materials that can be used to challenge patents in the U.S. and limits the
ability  to  rely  on  prior  research  to  lay  claim  to  patent  rights.  Under  the  current  system,  disputes  are  resolved  through  new  derivation  proceedings,  and  the  AIA  includes  mechanisms  to  allow
challenges to issued patents in reexamination, inter partes review and post grant proceedings. The AIA also includes bases and procedures that may make it easier for competitors to challenge our
patents, which could result in increased competition and have a material adverse effect on our business and results of operations. The AIA may also make it harder to challenge third-party patents and
place greater importance on being the first inventor to file a patent application on an invention. The AIA amendments to patent filing and litigation procedures in the U.S. may result in litigation being
more complex and expensive and divert the efforts of our technical and management personnel.

In addition, the patent positions of companies in the development and commercialization of pharmaceuticals may be particularly uncertain. Depending on future actions by the U.S. Congress, the U.S.
federal courts, and the USPTO, or by similarly legislative, judicial, and regulatory authorities in other jurisdictions, the laws and regulations governing patents could change in unpredictable ways that
could have a material adverse effect on our existing patent portfolio and our ability to protect and enforce our intellectual property in the future.

Third parties may claim that our product candidate or future product candidates infringe their rights, and we may incur significant costs resolving these claims. Additionally, legal proceedings
related to such claims could materially delay or otherwise adversely affect commercialization plans related to our product candidate, if approved.

Third  parties  may  claim  infringement  of  their  patents  and  other  intellectual  property  rights  by  the  manufacture,  use,  import,  offer  for  sale  or  sale  of  our  drug  delivery  technologies  or  our  other
products. For example, in connection with us seeking regulatory approval for a product candidate, a third party may allege that our product candidate infringes its patents or other intellectual property
rights and file suit to delay/prevent regulatory approval and/or commercialization of such product. In response to any claim of infringement, we may choose or be forced to seek licenses, defend
infringement actions or challenge the validity or enforceability of those patent rights in court or administrative proceedings. If we cannot obtain required licenses on commercially reasonably terms,
or at all, are found liable for infringement or are not able to have such patent rights declared invalid or unenforceable, our business could be materially harmed. We may be subject to claims (and even
held liable) for significant monetary damages (including enhanced damages and/or attorneys’ fees), encounter significant delays in bringing products to market or be precluded from the manufacture,
use, import, offer for sale or sale of products or methods of drug delivery covered by the patents of others. Even if a license is available, it may not be available on commercially reasonable terms or
may be non-exclusive, which could result in our competitors gaining access to the same intellectual property. We may not have identified, or be able to identify in the future, U.S. or non-U.S. patents
that pose a risk of potential infringement claims.

In addition to the possibility of intellectual property infringement claims, a third party could submit a citizen’s petition to the FDA requesting relief that, if granted, could materially adversely affect
the NDA and/or underlying product candidate. For example, such a third-party petition could, if granted, materially adversely affect the likelihood and/or timing of NDA approval, content of final
product labeling, and/or resulting regulatory exclusivity (if any) for such product.

Parties making claims against us may be able to sustain the costs of patent litigation more effectively than we can because they have substantially greater resources. In addition, any claims, with or
without merit, that our product candidate, future product candidates or drug delivery technologies infringe proprietary rights of third parties could be time-consuming, result in costly litigation or
divert the efforts of our technical and management personnel, any of which could disrupt our relationships with our partners and could significantly harm our financial positions and operating results.

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.

FT218 was submitted under Section 505(b)(2) of the FDCA. Section 505(b)(2) permits the submission of an NDA where at least some of the information required for approval comes from preclinical
studies or clinical trials that were not conducted by, or for, the applicant and for which the applicant has not obtained a right of reference. A 505(b)(2) NDA enables the applicant to

-43-

reference published literature for which the applicant does not have a right of reference and the FDA’s previous findings of safety and effectiveness for a previously approved drug.

For  505(b)(2)  NDAs,  the  patent  certification  and  related  provisions  of  the  Hatch-Waxman  Amendments  apply.  Accordingly,  if  the  applicant  relies  for  approval  on  the  safety  or  effectiveness  on
information for a previously approved drug, referred to as a listed drug, the applicable is required to include patent certifications in our 505(b)(2) NDA regarding any applicable patents covering the
listed drug. If there are applicable patents listed in the FDA publication Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book, for the listed
drug, and the applicant seeks to obtain approval prior to the expiration of one or more of those patents, the applicant is 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 the 505(b)(2) application. Otherwise, the 505(b)(2) NDA
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 FT218, there can be no assurance that we will not be required to submit a Paragraph IV certification in respect of FT218 or any future product candidates for which we seek
approval under Section 505(b)(2).

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.  Under  the  Hatch-Waxman
Amendments, 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) NDA will not be approved until any applicable 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) NDAs 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 a Section 505(b)(1) NDA or a Section 505(j) 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 and determines that our product is inappropriate for review through the 505(b)(2) pathway. These factors, among others, may limit our ability
to commercialize our product candidates successfully.

If we or our partners are required to obtain licenses from third parties, our revenues and royalties on any future commercialized products could be reduced.

The development of certain products based on our drug delivery technologies may require the use of raw materials (e.g., proprietary excipient), active ingredients, drugs (e.g., proprietary proteins) or
technologies developed by third parties. The extent to which efforts by other researchers have resulted or will result in patents and the extent to which we or our partners are forced to obtain licenses
from others, if available, on commercially reasonable terms is currently unknown. If we or our partners must obtain licenses from third parties, fees may be required for such licenses, which could
reduce the net revenues and royalties we receive on any future commercialized products that incorporate our drug delivery technologies.

Patent terms may be inadequate to protect our competitive position on our product candidate or future product candidates for an adequate amount of time.

Patents have a limited lifespan. In the U.S., if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various
extensions may be available, but the life of a patent, and the protection it affords, is limited. Even if patents covering our product candidate and future product candidates are obtained, once the patent
life has expired, we may be open to competition from competitive products, including generics or biosimilars. Given the amount of time required for the development, testing and regulatory review of
new product candidates, patents protecting such candidates might expire before or shortly after such candidates are commercialized. As a result, our owned and licensed patent portfolio may not
provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

Obtaining and maintaining our 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

-44-

eliminated for non-compliance with these requirements.

Periodic  maintenance  fees,  renewal  fees,  annuity  fees  and  various  other  governmental  fees  on  patents  and/or  applications  will  be  due  to  be  paid  to  the  USPTO  and  various  governmental  patent
agencies outside of the U.S. in several stages over the lifetime of the patents and/or applications. We rely on our outside counsel to coordinate payment of these fees due to patent agencies. The
USPTO and various non-U.S. governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application
process. We employ reputable law firms and other professionals to help us comply, and in many cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with
the applicable rules. However, there are situations in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights
in the relevant jurisdiction. In such an event, our competitors might be able to enter the market and this circumstance would have a material adverse effect on our business.

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

Filing, prosecuting and defending patents on our product candidate and future product candidates in all countries throughout the world would be prohibitively expensive, and intellectual property
rights in some countries outside the U.S. can be less extensive than those in the U.S. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside
the U.S., or from selling or importing products made using our inventions in and into the U.S. or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained
patent protection to develop their own products and may also export infringing products to territories where we have patent protection, but enforcement is not as strong as that in the U.S. These
products may compete with our product candidate and future product candidates and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in non-U.S. jurisdictions. The legal systems of certain countries, particularly certain
developing countries, do not favor the enforcement of patents, trade secrets, and other intellectual property protection, which could make it difficult for us to stop the infringement of our patents or
marketing  of  competing  products  in  violation  of  our  proprietary  rights  generally.  Proceedings  to  enforce  our  patent  rights  in  non-U.S.  jurisdictions,  whether  or  not  successful,  could  result  in
substantial costs and divert our efforts and attention from other aspects of our business, 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 we initiate, and the damages or other remedies awarded, if any, may not be commercially
meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property we
develop or license.

Risks Related to Acceptance, Sales, Marketing and Competition

If we are unable to establish effective sales, marketing and distribution capabilities for FT218, if approved, or enter into agreements with third parties to market, sell and distribute our product
candidate, if approved, or if we are unable to achieve market acceptance for FT218, our business, results of operations, financial condition and prospects will be materially adversely affected.

We are continuing to build the systems, processes, policies, relationships and materials necessary for the launch of FT218 in the U.S. for the treatment of cataplexy or EDS in adults with narcolepsy.
If we receive regulatory approval to market or sell FT218, but are unable to establish adequate sales, marketing and distribution capabilities, whether independently or with third parties, or if we are
unable to do so on commercially reasonable terms, our business, results of operations, financial condition and prospects will be materially adversely affected. We may encounter issues, delays or
other challenges in launching or commercializing FT218.

We have limited experience in building and managing a commercial team, conducting a comprehensive market analysis, obtaining state licenses and reimbursement, or managing distributors and a
sales  force  for  our  medicines.  For  example,  our  results  may  be  negatively  impacted  if  we  have  not  adequately  sized  our  field  teams  or  if  our  targeting  strategy  is  inadequate  or  if  we  encounter
deficiencies or inefficiencies in our infrastructure or processes. We will be competing with many companies that currently have extensive and well-funded sales and marketing operations. As a result,
our ability to successfully commercialize FT218 may involve more inherent risk, take longer, and cost more than it would if we were a company with substantial experience in launching medicines.

We will have to compete with other pharmaceutical and biotechnology companies to recruit, hire, train and retain marketing and sales personnel. If we are unable to, or decide not to, further develop
internal sales, marketing, and commercial distribution

-45-

capabilities for FT218 in any country or region, we will likely pursue collaborative arrangements regarding the sales and marketing of FT218. However, there can be no assurance that we will be able
to establish or maintain such collaborative arrangements, or if we are able to do so, that they will have effective sales forces. Any revenue we receive will depend upon the efforts of such third parties.
We would have little or no control over the marketing and sales efforts of such third parties, and our revenue from product sales may be lower than if we had commercialized FT218 ourselves. We
also face competition in our search for third parties to assist us with the sales and marketing efforts for our medicines.

Any of these issues could impair our ability to successfully commercialize FT218 or to generate substantial revenues or profits or to meet our expectations with respect to the amount or timing of
revenues or profits. There is no guarantee that we will be successful in our launch or commercialization efforts with respect to FT218, if approved, or with respect to any other product candidate that
may be approved in the future.

If the market opportunities for FT218 are smaller than we believe they are, and if we are not able to successfully identify patients and achieve significant market share, our revenues may be
adversely affected and our business may suffer.

FT218  is  an  investigational  formulation  of  sodium  oxybate  designed  to  be  taken  once  at  bedtime  for  the  treatment  of  EDS  or  cataplexy  in  adults  with  narcolepsy.  Our  estimates  of  the  market
opportunities for FT218 are based on the estimated market size for the twice-nightly administration of sodium oxybate, which is the current standard of care for EDS or cataplexy in patients with
narcolepsy, and our expectations with regard to FT218’s potential to take a significant share of this market. These estimates have been derived from a variety of sources, including scientific literature,
surveys of clinics, patient foundations, or market research, and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these diseases. The potential
target population for FT218 may turn out to be lower or more difficult to identify than expected. Even if we obtain significant market share for FT218 in this indication, because the potential target
population for FT218 is small, we may never achieve profitability without obtaining marketing approval for additional indications.

Any of these factors may negatively affect our ability to recognize revenues from sales of FT218 and our ability to achieve and maintain profitability and, as a consequence, our business may suffer.

FT218, if approved, may not gain market acceptance.

FT218, if approved, may not gain market acceptance among physicians, patients, healthcare payor and medical communities. The degree of market acceptance of FT218, if approved, will depend on
a number of factors, including, but not limited to:

•

•
•
•
•
•
•
•
•
•
•
•
•
•

the  clinical  indications  for  which  FT218  is  approved  and  any  restrictions  placed  upon  the  product  in  connection  with  its  approval,  such  as  a  REMS  or  equivalent  obligation  by  other
regulatory authorities, patient registry requirements or labeling restrictions;
the prevalence of the disease or condition for which FT218 is approved and its diagnosis;
scheduling classification of sodium oxybate as a controlled substance regulated by the DEA;
demonstration of the clinical safety and efficacy of the product or technology;
the absence of evidence of undesirable side effects of the product or technology that delay or extend trials;
acceptance by physicians and patients of each product as a safe and effective treatment;
availability of sufficient product inventory to meet demand;
physicians’ decisions relating to treatment practices based on availability;
physician and patient assessment of the burdens associated with obtaining or maintaining the certifications required under the FT218 REMS, if approved;
the lack of regulatory delays or other regulatory actions;
its cost-effectiveness and related access to payor coverage;
its potential advantage over alternative treatment methods;
the availability of third-party reimbursement or other assistance for patients who are uninsured or underinsured; and
the marketing and distribution support it receives.

If FT218, if approved, fails to achieve market acceptance, our ability to generate revenue will be limited, which would have a material adverse effect on our business.

-46-

FT218, if approved, will be subject to ongoing enforcement of post-marketing requirements and we could be subject to substantial penalties, including withdrawal of FT218 from the market, if
we  fail  to  comply  with  all  regulatory  requirements.  In  addition,  the  terms  of  the  marketing  approval  of  FT218,  if  approved,  and  ongoing  regulation  of  our  product,  may  limit  how  we
manufacture and market FT218 and compliance with such requirements may involve substantial resources, which could materially impair our ability to generate revenue.

If approved, FT218, along with the manufacturing processes, post-approval clinical data, labeling, advertising, and promotional activities for FT218, will be subject to continual requirements of and
review by the FDA and other applicable regulatory authorities. These requirements include, but are not limited to, restrictions governing promotion of an approved product, submissions of safety and
other post-marketing information and reports, registration and listing requirements, cGMP requirements relating to manufacturing, quality control, quality assurance and corresponding maintenance
of records and documents, and requirements regarding drug distribution and the distribution of samples to physicians and recordkeeping.

In the U.S., the FDA and other federal and state agencies, including the Department of Justice, closely regulate compliance with all requirements governing prescription drug products, including
requirements  pertaining  to  marketing  and  promotion  of  drugs  in  accordance  with  the  provisions  of  the  approved  labeling  and  manufacturing  of  products  in  accordance  with  cGMP  requirements.
Violations of such requirements may lead to investigations alleging violations of the FDCA and other statutes, including the FDA and other federal and state healthcare fraud and abuse laws as well
as  state  consumer  protection  laws.  Our  failure  to  comply  with  all  regulatory  requirements,  and  later  discovery  of  previously  unknown  adverse  events  or  other  problems  with  our  products,
manufacturers, or manufacturing processes, may yield various results, including:

litigation involving patients taking our products;
restrictions on such products, manufacturers, or manufacturing processes;
restrictions on the labeling or marketing of a product;
restrictions on product distribution or use;
requirements to conduct post-marketing studies or clinical trials;

•
•
•
•
•
• warning or untitled letters;
• withdrawal of the products from the market;
•
•
•
•
•
•
•
•
•

refusal to approve pending applications or supplements to approved applications that we submit;
voluntary recall of products;
fines, restitution, or disgorgement of profits or revenues;
suspension or withdrawal of marketing approvals;
damage to relationships with any potential collaborators;
unfavorable press coverage and damage to our reputation;
refusal to permit the import or export of our products;
product seizure; or
injunctions or the imposition of civil or criminal penalties.

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

In addition, we and our CDMOs will continue to expend time, money, and effort in all areas of regulatory compliance, including manufacturing, production, product surveillance, quality control and
distribution. Under the DSCSA, for certain commercial prescription drug products, manufacturers and other parties involved in the supply chain must also meet chain of distribution requirements and
build electronic, interoperable systems for product tracking and tracing and for notifying the FDA of counterfeit, diverted, stolen, and intentionally adulterated products or other products that are
otherwise unfit for distribution in the U.S. In addition, the distribution of prescription pharmaceutical products, including samples, is subject to the PDMA, which regulations the distribution of drugs
and  drug  samples  at  the  federal  level,  and  sets  minimum  standards  for  the  registration  and  regulation  of  drug  distributors  by  the  states.  Both  the  PDMA  and  state  laws  limit  the  distribution  of
prescription  pharmaceutical  product  samples  and  impose  requirements  to  ensure  accountability  in  distribution.  Prescription  drug  products  must  also  meet  applicable  child-resistant  packaging
requirements under the U.S. Poison Prevention Packaging Act. We, our CDMOs and other third parties upon whom we rely will be subject to applicable controlled substances laws, regulations and
requirements. If FT218 is approved and we are not able to comply with post-approval regulatory requirements, we could have the marketing approvals for FT218 withdrawn by regulatory authorities
and our ability to market FT218 could be limited, which could adversely affect our ability to achieve or sustain profitability and we could be subject to substantial penalties. As a result, the cost of
compliance with post-approval regulations may have a negative effect on our operating results and financial condition.

-47-

If our competitors develop and market technologies or products that are safer or more effective than ours, or obtain regulatory approval and market such products before we do, our commercial
opportunity will be diminished or eliminated.

Competition in the pharmaceutical and biotechnology industry is intense and is expected to increase. We compete with academic laboratories, research institutions, universities, joint ventures and
other  pharmaceutical  and  biotechnology  companies,  including  companies  developing  drug  delivery  technologies  or  niche  brand  or  generic  specialty  pharmaceutical  products.  Some  of  these
competitors may also be our business partners.

If the FDA approves a competitor’s application for a product candidate before our application for a similar product candidate, and grants such competitor a period of exclusivity, the FDA may take
the position that it cannot approve our 505(b)(2) application for a similar product candidate until the exclusivity period expires. Additionally, even if our 505(b)(2) application for a product candidate
is approved first, and we receive a period of statutory marketing exclusivity, we may still be subject to competition from other companies with approved products or approved 505(b)(2) NDAs for
different conditions of use that would not be restricted by a grant of exclusivity to us.

Many of our competitors have substantially greater financial, technological, manufacturing, marketing, managerial and research and development resources and experience than we do. Furthermore,
acquisitions of competing companies by large pharmaceutical companies could enhance our competitors’ resources. Accordingly, our competitors may be able to develop, obtain regulatory approval
and gain market share for their products more rapidly than us.

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

Once an NDA, including a 505(b)(2) NDA, is approved, the product covered becomes a “listed drug” which can be cited by potential competitors in support of approval of an ANDA or subsequent
505(b)(2) application. 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  based  off  recently  approved  NDAs.  The  Creating  and  Restoring  Equal  Access  to  Equivalent  Samples  Act  (“CREATES  Act”)  was  enacted  in  2019
requiring sponsors of approved NDAs to provide sufficient quantities of product samples on commercially reasonable, market-based terms to entities developing generic drugs. The law establishes a
private right of action allowing developers to sue listed drug holders that refuse to sell them product samples needed to support their applications. If we are required to provide product samples or
allocate additional resources to responding to such requests or any legal challenges under this law, our business could be adversely impacted. 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.

If  we  cannot  keep  pace  with  the  rapid  technological  change  in  our  industry,  we  may  lose  business,  and  our  product  candidates,  if  approved,  and  technologies  could  become  obsolete  or
noncompetitive.

Our success also depends, in part, on maintaining a competitive position in the development of products and technologies in a rapidly evolving field. Major technological changes can happen quickly
in the biotechnology and pharmaceutical industries. If we cannot maintain competitive products and technologies, our competitors may succeed in developing competing technologies or obtaining
regulatory  approval  for  products  before  us,  and  the  products  of  our  competitors  may  gain  market  acceptance  more  rapidly  than  our  product  candidate  and  future  product  candidates.  Such  rapid
technological change, or the development by our competitors of technologically improved or different products, could render our product candidate and future product candidates or technologies
obsolete or noncompetitive.

Risks Related to Our Business and Industry

COVID-19 may materially and adversely affect our business and our financial results.

The  COVID-19  pandemic  has  spread  globally.  The  continued  spread  of  COVID-19  could  adversely  impact  our  operations,  including  our  ability  to  fully  enroll  and  complete  RESTORE,  our
OLE/switch study of FT218, initiate and complete any future

-48-

clinical trials, manufacture sufficient supply of our FT218 at sufficient scale for commercialization, if approved. We submitted our 505(b)(2) NDA for FT218 in December 2020.

In  addition,  COVID-19  has  resulted  in  significant  governmental  measures  being  implemented  to  control  the  spread  of  the  virus,  including  quarantines,  travel  restrictions,  social  distancing  and
business shutdowns. We have taken temporary precautionary measures intended to help minimize the risk of the virus to our employees, including temporarily allowing employees to work remotely.
We  have  suspended  non-essential  travel  worldwide  for  our  employees  and  are  discouraging  employee  attendance  at  large  gatherings.  These  measures  could  negatively  affect  our  business.  For
instance, temporarily allowing employees to work remotely may induce absenteeism, disrupt our operations or increase the risk of a cybersecurity incident. COVID-19 has also caused volatility in the
global financial markets and threatened a slowdown in the global economy, which may negatively affect our ability to raise additional capital on attractive terms or at all.

Since  the  beginning  of  the  COVID-19  pandemic,  three  vaccines  for  COVID-19  have  received  Emergency  Use  Authorization  by  the  FDA  and  two  of  those  later  received  marketing  approval.
Additional vaccines may be authorized in the future. The resultant demand for vaccines and potential for manufacturing facilities and materials to be commandeered under the Defense Production Act
of 1950, or equivalent foreign legislation, may make it more difficult to obtain materials or manufacturing slots for the products needed for our OLE/switch clinical trial and future commercialization
of FT218, if approved, which could lead to delays in these activities.

The  extent  to  which  COVID-19  may  impact  our  business  will  depend  on  future  developments,  which  are  highly  uncertain  and  cannot  be  predicted  with  confidence,  such  as  the  duration  of  the
pandemic, the severity of COVID-19, the identification of new variations of the virus or the effectiveness of actions to contain and treat COVID-19, particularly in the geographies where we or our
third party suppliers and CDMOs, or CROs operate. We cannot presently predict the scope and severity of any potential business shutdowns or disruptions. If we or any of the third parties with whom
we engage, however, were to experience shutdowns or other business disruptions, our ability to conduct our business in the manner and on the timelines presently planned could be materially and
negatively affected, which could have a material adverse impact on our business and our results of operations and financial condition.

If we need to take further restructuring actions, necessary third-party consents may not be granted.

In February 2019, we announced a restructuring plan intended to achieve future cost savings through, among other actions, a reduction of our overall workforce by approximately 50 percent. Our
management may determine we need to take further restructuring actions to achieve additional cost savings, to generate additional capital needed for our business strategy, or for other purposes.
Certain restructuring scenarios that management consider could require obtaining the consent of third parties, such as holders of our Exchangeable Senior Notes due February 2023 (the “February
2023 Notes”). For example, the voluntary bankruptcy filing by Avadel Specialty Pharmaceuticals LLC (“Specialty Pharma”) required the consent of holders of a majority in principal amount of our
February 2023 Notes in order to avoid a default under the Indenture governing such February 2023 Notes. While we were successful in obtaining that consent, there can be no assurance we will be
successful in obtaining additional consents in the future from such holders or from other third parties whose consents may be required. Failure to obtain these third-party consents would prevent us
from taking additional restructuring actions, which could have a material adverse effect on our cash flow, financial resources and ability to successfully pursue our business strategy.

Risks Related to Litigation and Legal Matters

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 or other intellectual property. If we were to initiate legal proceedings against a third party to enforce a patent covering our product candidate or future product
candidates, the defendant could counterclaim that the patent is invalid and/or unenforceable. In patent litigation in the U.S., defendant counterclaims alleging invalidity and/or unenforceability are
commonplace.  Grounds  for  a  validity  challenge  could  be  an  alleged  failure  to  meet  any  of  several  statutory  requirements,  including  lack  of  novelty,  obviousness,  written  description  or  non-
enablement.  Grounds  for  an  unenforceability  assertion  could  be  an  allegation  that  someone  connected  with  prosecution  of  the  patent  withheld  relevant  information  from  the  USPTO,  or  made  a
misleading statement, during prosecution. There is risk that a court could rule in favor of the defendant with respect to such a counterclaim of patent invalidity and/or unenforceability.

Interference or derivation proceedings provoked by third parties or brought by us or declared by the USPTO may be necessary to determine the priority of inventions with respect to our patents or
patent applications. An unfavorable outcome could require

-49-

us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially
reasonable terms or at all, or if a non-exclusive license is offered and our competitors gain access to the same technology. Our defense of litigation or interference or derivation proceedings may fail
and, even if successful, may result in substantial costs and distract our management and other employees. In addition, the uncertainties associated with litigation could have a material adverse effect
on our ability to raise the funds necessary to continue our clinical trials, continue our research programs, license necessary technology from third parties, or enter into development partnerships that
would help us bring our product candidate and future product candidates to market.

Because of the substantial amount of discovery that can occur in connection with intellectual property-related litigation and/or administrative proceedings, there is a risk that some of our confidential
information could be compromised by disclosure during this type of litigation/proceeding. 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 have a material adverse effect on the price of our common stock.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties or that our employees have
wrongfully used or disclosed alleged trade secrets of their former employers.

We  employ  or  may  employ  individuals  who  were  previously  employed  at  universities  or  other  biotechnology  or  pharmaceutical  companies,  including  our  competitors  or  potential  competitors.
Although we endeavor to ensure that our employees, consultants and independent contractors do not use the proprietary information or know-how of others in their work for us, we may be subject to
claims  that  we  or  our  employees,  consultants  or  independent  contractors  have  inadvertently  or  otherwise  used  or  disclosed  intellectual  property,  including  trade  secrets  or  other  proprietary
information, of any of our employee’s former employer or other third parties. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying
any  awarded  monetary  damages,  we  may  lose  valuable  intellectual  property  rights  or  personnel,  which  could  adversely  impact  our  business.  Even  if  we  are  successful  in  defending  against  such
claims, litigation could result in substantial costs and/or be a distraction to management and other employees.

We  and  companies  to  which  we  have  licensed,  or  will  license  our  future  products  or  drug  delivery  technologies  and  subcontractors  we  engage  or  may  engage  for  services  related  to  the
development  and  manufacturing  of  our  lead  product  candidate  or  future  product  candidates  are  subject  to  extensive  regulation  by  the  FDA  and  other  regulatory  authorities.  Our  and  their
failure to meet strict regulatory requirements could adversely affect our business.

We, and companies to which we will license our future products or drug delivery technologies, as well as companies acting as subcontractors for our product developments, including but not limited
to non-clinical, pre-clinical and clinical studies, and manufacturing, are subject to extensive regulation by the FDA, other U.S. authorities and equivalent non-U.S. regulatory authorities, particularly
the  European  Commission  and  the  competent  authorities  of  EU  Member  States.  Those  regulatory  authorities  may  conduct  periodic  audits  or  inspections  of  the  applicable  facilities  to  monitor
compliance  with  regulatory  standards  and  we  remain  responsible  for  the  compliance  of  our  subcontractors.  If  the  FDA  or  another  regulatory  authority  finds  failure  to  comply  with  applicable
regulations, the authority may institute a wide variety of enforcement actions, including:

fines and civil penalties;
delays in clearing or approving, or refusal to clear or approve, products;

• warning letters or untitled letters;
•
•
• withdrawal, suspension or variation of approval of products; product recall or seizure;
•
•
•
•
•
•

orders to the competent authorities of EU Member States to withdraw or vary national authorization;
orders for physician notification or device repair, replacement or refund;
interruption of production;
operating restrictions;
injunctions; and
criminal prosecution.

Any adverse action by a competent regulatory agency could lead to unanticipated expenditures to address or defend such action and may impair our ability to produce and market applicable products,
which could significantly impact our revenues and royalties that we would be eligible to receive from our potential customers.

We may face product liability claims related to clinical trials for our product candidate or future product candidates or their misuse.

-50-

The testing, including through clinical trials, manufacturing and marketing, and the use of our product candidate and future product candidates may expose us to potential product liability and other
claims.  If  any  such  claims  against  us  are  successful,  we  may  be  required  to  make  significant  compensation  payments.  Any  indemnification  that  we  have  obtained,  or  may  obtain,  from  CROs  or
pharmaceutical  and  biotechnology  companies  or  hospitals  conducting  human  clinical  trials  on  our  behalf  may  not  protect  us  from  product  liability  claims  or  from  the  costs  of  related  litigation.
Insurance coverage is expensive and difficult to obtain, and we may be unable to obtain coverage in the future on acceptable terms, if at all. We currently maintain general liability insurance and
product liability insurance. We cannot be certain that the coverage limits of our insurance policies or those of our strategic partners will be adequate. If we are unable to obtain sufficient insurance at
an acceptable cost, a product liability claim or recall could adversely affect our financial condition.

Similarly,  any  indemnification  we  have  obtained,  or  may  obtain,  from  pharmaceutical  and  biotechnology  companies  with  whom  we  are  developing,  or  will  develop,  our  future  products  may  not
protect us from product liability claims from the consumers of those products or from the costs of related litigation.

If we use hazardous biological and/or chemical materials in a manner that causes injury, we may be liable for significant damages.

Our R&D activities involve the controlled use of potentially harmful biological and/or chemical materials, and are subject to U.S., state, EU, national and local laws and regulations governing the use,
storage,  handling  and  disposal  of  those  materials  and  specified  waste  products.  We  cannot  completely  eliminate  the  risk  of  accidental  contamination  or  injury  from  the  use,  storage,  handling  or
disposal of these materials, including fires and/or explosions, storage tank leaks and ruptures and discharges or releases of toxic or hazardous substances. These operating risks can cause personal
injury, property damage and environmental contamination, and may result in the shutdown of affected facilities and the imposition of civil or criminal penalties. The occurrence of any of these events
may significantly reduce the productivity and profitability of a particular manufacturing facility and adversely affect our operating results.

We currently maintain property, business interruption and casualty insurance with limits that we believe to be commercially reasonable but may be inadequate to cover any actual liability or damages.

Risks Related to Ownership of Our Securities

The price of ADSs representing our ordinary shares has been volatile and may continue to be volatile.

The trading price of ADSs has been, and is likely to continue to be, highly volatile. The market value of an investment in ADSs may fall sharply at any time due to this volatility. During the year
ended December 31, 2021, the closing sale price of ADSs as reported on the Nasdaq Global Market ranged from $6.49 to $11.18. During the year ended December 31, 2020, the closing sale price of
ADSs  as  reported  on  the  Nasdaq  Global  Market  ranged  from  $4.06  to  $11.75.  The  market  prices  for  securities  of  drug  delivery,  specialty  pharma,  biotechnology  and  pharmaceutical  companies
historically have been highly volatile. Factors that could adversely affect our share price include, among others:

•
•
•
•
•
•
•
•
•
•
•
•
•
•

fluctuations in our operating results;
announcements of technological partnerships, innovations or new products by us or our competitors;
actions with respect to the acquisition of new or complementary businesses;
governmental regulations;
developments in patent or other proprietary rights owned by us or others;
public concern as to the safety of drug delivery technologies developed by us or drugs developed by others using our platform;
the results of pre-clinical testing and clinical studies or trials by us or our competitors;
adverse events related to our product candidate or future product candidates;
lack of efficacy of our product candidate or future product candidates;
litigation;
decisions by our pharmaceutical and biotechnology company partners relating to the products that may incorporate our technologies;
the perception by the market of specialty pharma, biotechnology, and high technology companies generally;
general market conditions, including the impact of the current financial environment; and
the dilutive impact of any new equity or convertible debt securities we may issue or have issued.

Risks Related to the 2023 Notes

Servicing our February 2023 Notes and our October 2023 Notes (as defined below) may require a significant amount of cash, and we may not have sufficient cash or the ability to raise the funds
necessary to settle exchanges of the 2023 Notes in cash, repay the Notes at maturity, or repurchase the 2023 Notes as required following a fundamental change.

In February 2018, we issued $143,750 aggregate principal amount of our February 2023 Notes. Prior to February 2023, the February 2023 Notes are convertible at the option of the holders only under
certain conditions or upon the occurrence of certain events. On March 16, 2022, we executed an agreement to exchange $117,375 of the February 2023 Notes for a new series of Exchangeable Senior
Notes due October 2, 2023 (the “October 2023 Notes”). We refer to the February 2023 Notes and the October 2023 Notes as the “2023 Notes”.

If holders of the 2023 Notes elect to exchange their 2023 Notes, unless we elect to deliver solely our ADSs to settle such exchanges, we will be required to make cash payments in respect of the 2023
Notes being exchanged. Holders of the 2023 Notes also have the right to require us to repurchase all or a portion of their 2023 Notes upon the occurrence of a fundamental change (as defined in the
applicable indenture governing the 2023 Notes) at a repurchase price equal to 100% of the principal amount of the 2023 Notes to be repurchased, plus accrued and unpaid interest. If the 2023 Notes
have not previously been exchanged or repurchased, we will be required to repay the 2023 Notes in cash at maturity. Our ability to make cash payments in connection with exchanges of the 2023
Notes, repurchase the 2023 Notes in the event of a fundamental change, or to repay or refinance the 2023 Notes at maturity will depend on market conditions and our future performance, which is
subject to economic, financial, competitive, and other factors many of which are beyond our control. We had limited net income in 2020 and incurred a net loss in 2021. As a result, we may not have
enough available cash or be able to obtain financing at the time we are required to repurchase or repay the 2023 Notes or in the event we elect to pay cash with respect to 2023 Notes being exchanged.

The conditional exchange feature of the 2023 Notes, if triggered, may adversely affect our financial condition and operating results.

In the event the conditional exchange feature of the 2023 Notes is triggered, holders of 2023 Notes will be entitled to exchange the 2023 Notes at any time during specified periods at their option. If
one or more holders elect to exchange their 2023 Notes, unless we elect to satisfy our exchange obligation by causing to be delivered solely ADSs (other than paying cash in lieu of any fractional
ADSs), we would be required to settle a portion or all of our exchange obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to
exchange their 2023 Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the 2023 Notes as a current rather than long-term
liability, which would result in a material reduction of our net working capital.

The accounting method for convertible and exchangeable debt securities that may be settled in cash, such as the 2023 Notes, could have a material effect on our reported financial results.

In  accordance  with  Financial  Accounting  Standards  Board  (“FASB”)  Accounting  Standards  Codification  (“ASC”)  Topic  470,  Debt,  an  entity  must  separately  account  for  the  liability  and  equity
components of convertible debt instruments (such as the 2023 Notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer’s economic interest cost. ASC
470-20 requires the value of the conversion option of the 2023 Notes, representing the equity component, to be recorded as additional paid-in capital within stockholders’ equity in our consolidated
balance sheets and as a discount to the 2023 Notes, which reduces their initial carrying value. In addition, under the treasury stock method, if the conversion value of the 2023 Notes exceeds their
principal amount for a reporting period, then we will calculate our diluted earnings per share assuming that all the 2023 Notes were converted and that we issued shares of our common stock to settle
the excess. However, if reflecting the 2023 Notes in diluted earnings per share in this manner is anti-dilutive, or if the conversion value of the 2023 Notes does not exceed their principal amount for a
reporting period, then the shares of common stock underlying the 2023 Notes will not be reflected in our diluted earnings per share.

In August 2020, the FASB issued Accounting Standards Update (“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 (“ASU 2020-06”), which eliminates the beneficial conversion and cash
conversion  accounting  models  for  convertible  instruments.  This  would  reduce  non-cash  interest  expense,  and  thereby  decrease  net  loss  (or  increase  net  income).  Additionally,  the  treasury  stock
method for calculating earnings per share will no longer be allowed for convertible debt instruments whose principal amount may be settled using shares and the if-converted method will be required.

-52-

We elected to early adopt ASU 2020-06 beginning with our fiscal year ending December 31, 2021, including any interim periods within that fiscal year. Under ASU 2020-06, the 2023 Notes will be
subject to the “if-converted” method for calculating diluted earnings per share. Accordingly, under the “if-converted” method, diluted earnings per share will be calculated assuming that all of the
Convertible Notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be anti-dilutive. This new method of calculating earnings per
share may adversely affect our reported financial condition and results.

If any of the conditions to the convertibility of the 2023 Notes is satisfied, then we may be required under applicable accounting standards to reclassify the liability carrying value of the 2023 Notes as
a current, rather than a long-term, liability. This reclassification could be required even if no noteholders convert their 2023 Notes and could materially reduce our reported working capital.

Exchanges of the 2023 Notes will dilute the ownership interest of our existing shareholders and holders of the ADSs, including holders who may exchange their 2023 Notes and receive ADSs
upon exchange, to the extent our exchange obligation includes ADSs.

The exchange of some or all of the 2023 Notes will dilute the ownership interests of our existing shareholders and holders of the ADSs to the extent our exchange obligation includes ADSs. Any
sales in the public market of the ADSs issuable upon such exchange of the 2023 Notes could adversely affect prevailing market prices of the ADSs and, in turn, the price of the 2023 Notes. In
addition, the existence of the 2023 Notes may encourage short selling by market participants because the exchange of the 2023 Notes could depress the price of the ADSs.

The fundamental change repurchase feature of the 2023 Notes may delay or prevent an otherwise beneficial takeover attempt of Avadel.

The indenture governing the 2023 Notes will require us to repurchase the 2023 Notes for cash upon the occurrence of a fundamental change and, in certain circumstances, to increase the exchange
rate for a holder that exchanges its 2023 Notes in connection with a make-whole fundamental change. A takeover of Avadel may trigger the requirement that we repurchase the 2023 Notes and/or
increase  the  exchange  rate,  which  could  make  it  more  costly  for  a  potential  acquirer  to  engage  in  a  combinatory  transaction  with  us.  Such  additional  costs  may  have  the  effect  of  delaying  or
preventing a takeover of Avadel that would otherwise be beneficial to investors.

If we pay dividends, the dividends may be subject to Irish dividend withholding tax

In  certain  circumstances,  as  an  Irish  tax  resident  company,  we  may  be  required  to  deduct  Irish  dividend  withholding  tax  (currently  at  the  rate  of  20%)  from  dividends  paid  to  its  shareholders.
Shareholders that are resident in the U.S., EU countries (other than Ireland) or other countries with which Ireland has signed a tax treaty (whether the treaty has been ratified or not) generally should
not be subject to Irish withholding tax so long as the shareholder has provided its broker, for onward transmission to our qualifying intermediary or other designated agent (in the case of shares held
beneficially),  or  us  or  our  transfer  agent  (in  the  case  of  shares  held  directly),  with  all  the  necessary  documentation  by  the  appropriate  due  date  prior  to  payment  of  the  dividend.  However,  some
shareholders may be subject to withholding tax, which could adversely affect the price of ordinary shares and the value of their 2023 Notes.

General Risk Factors

Provisions of our articles of association could delay or prevent a third-party’s effort to acquire us.

Our articles of association could delay, defer or prevent a third-party from acquiring us, even where such a transaction would be beneficial to the holders of ADSs, or could otherwise adversely affect
the price of ADSs. For example, certain provisions of our articles of association:

•
•
•

permit our board of directors to issue preferred shares with such rights and preferences as they may designate, subject to applicable law;
impose advance notice requirements for shareholder proposals and director nominations to be considered at annual shareholder meetings; and
require  the  approval  of  a  supermajority  of  the  voting  power  of  our  shares  entitled  to  vote  at  a  general  meeting  of  shareholders  to  amend  or  repeal  any  provisions  of  our  articles  of
association.

-53-

We believe these provisions, if implemented in compliance with applicable law, may provide some protection to holders of ADSs from coercive or otherwise unfair takeover tactics. These provisions
are not intended to make us immune from takeovers. They will, however, apply even if some holders of ADSs consider an offer to be beneficial and could delay or prevent an acquisition that our
Board of Directors determines is in the best interest of the holders of ADSs. Certain of these provisions may also prevent or discourage attempts to remove and replace incumbent directors.

In addition, mandatory provisions of Irish law could prevent or delay an acquisition of the Company by a third party. For example, Irish law does not permit shareholders of an Irish public limited
company to take action by written consent with less than unanimous consent. In addition, an effort to acquire us may be subject to various provisions of Irish law relating to mandatory bids, voluntary
bids, requirements to make a cash offer and minimum price requirements, as well as substantial acquisition rules and rules requiring the disclosure of interests in ADSs in certain circumstances.

These provisions may discourage potential takeover attempts or bids for our ordinary shares at a premium over the market price or they may adversely affect the market price of, and the voting and
other rights of the holders of, ADSs. These provisions could also discourage proxy contests and make it more difficult for holders of ADSs to elect directors other than the candidates nominated by
our board of directors and could depress affect the market price of ADSs.

Irish law differs from the laws in effect in the U.S. and might afford less protection to the holders of ADSs.

Holders  of  ADSs  could  have  more  difficulty  protecting  their  interests  than  would  the  shareholders  of  a  U.S.  corporation.  As  an  Irish  company,  we  are  governed  by  Irish  law,  including  the  Irish
Companies  Act  2014  and  the  Irish  Takeover  Rules,  which  differs  in  some  significant,  and  possibly  material,  respects  from  provisions  set  forth  in  various  U.S.  state  laws  applicable  to  U.S.
corporations and their shareholders, including provisions relating to interested directors, mergers and acquisitions, takeovers, shareholder lawsuits and indemnification of directors.

The  duties  of  directors  and  officers  of  an  Irish  company  are  generally  owed  to  the  company  only.  Therefore,  under  Irish  law  shareholders  of  Irish  companies  do  not  generally  have  a  right  to
commence a legal action against directors or officers and may only do so in limited circumstances. Directors of an Irish company must act with due care and skill, honestly and in good faith with a
view to the best interests of the company. Directors must not put themselves in a position in which their duties to the company and their personal interests conflict and must disclose any personal
interest in any contract or arrangement with the company or any of our subsidiaries. A director or officer can be held personally liable to the company in respect of a breach of duty to the company.

Judgments of U.S. courts, including those predicated on the civil liability provisions of the federal securities laws of the U.S., may not be enforceable in Irish courts.

An investor in the U.S. may find it difficult to:

•
•
•

effect service of process within the U.S. against us and our non-U.S. resident directors and officers;
enforce U.S. court judgments based upon the civil liability provisions of the U.S. federal securities laws against us and our non-U.S. resident directors and officers in Ireland; or
bring an original action in an Irish court to enforce liabilities based upon the U.S. federal securities laws against us and our non-U.S. resident directors and officers.

Judgments of U.S. courts, including those predicated on the civil liability provisions of the federal securities laws of the United States, may not be enforceable in Cayman Islands courts.

We have been advised by our Cayman Islands legal counsel, Maples and Calder, that the courts of the Cayman Islands are unlikely (i) to recognize or enforce against us or Avadel judgments of courts
of the U.S. predicated upon the civil liability provisions of the securities laws of the U.S. or any State; and (ii) in original actions brought in the Cayman Islands, to impose liabilities against us or
Avadel predicated upon the civil liability provisions of the securities laws of the U.S. or any State, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances,
although there is no statutory enforcement in the Cayman Islands of judgments obtained in the U.S., the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a
foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum
for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated
sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner,
and or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the

-54-

Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands Court may stay enforcement proceedings if concurrent proceedings are
being brought elsewhere.

Holders of ADSs have fewer rights than shareholders and have to act through the Depositary to exercise those rights.

Holders of ADSs do not have the same rights as shareholders and, accordingly, cannot exercise rights of shareholders against us. The Bank of New York Mellon, as depositary (the “Depositary”), is
the registered shareholder of the deposited shares underlying the ADSs. Therefore, holders of ADSs will generally have to exercise the rights attached to those shares through the Depositary. We will
use reasonable efforts to request that the Depositary notify the holders of ADSs of upcoming votes and ask for voting instructions from them. If a holder fails to return a voting instruction card to the
Depositary by the date established by the Depositary for receipt of such voting instructions, or if the Depositary receives an improperly completed or blank voting instruction card, or if the voting
instructions included in the voting instruction card are illegible or unclear, then such holder will be deemed to have instructed the Depositary to vote its shares, and the Depositary shall vote such
shares in favor of any resolution proposed or approved by our Board of Directors and against any resolution not so proposed or approved.

Security breaches and other disruptions could compromise confidential information and expose us to liability and cause our business and reputation to suffer.

In the ordinary course of our business, we collect and store on our networks various intellectual property including our proprietary business information and that of former customers, suppliers and
business  partners.  The  secure  maintenance  and  transmission  of  this  information  is  critical  to  our  operations  and  business  strategy.  Despite  our  security  measures,  our  information  systems  and
infrastructure  may  be  vulnerable  to  disruptions  such  as  computer  hacking,  phishing  attacks,  ransomware,  dissemination  of  computer  viruses,  worms  and  other  destructive  or  disruptive  software,
attacks by hackers or breached due to employee error, malfeasance or other disruptions. Any such breach could compromise our networks and the information stored there could be accessed, publicly
disclosed, lost or stolen. Any such access, disclosure or other loss of information could result in legal claims or proceedings, investigations by regulatory authorities in the U.S. and EU Member
States, disruption to our operations and damage to our reputation, any of which could adversely affect our business.

We could suffer financial loss or the loss of valuable confidential information. Although we develop and maintain systems and controls designed to prevent these events from occurring and we have a
process to identify and mitigate threats, the development and maintenance of these systems, controls and processes is costly and requires ongoing monitoring and updating as technologies change and
efforts to overcome security measures become increasingly sophisticated. Moreover, despite our efforts, the possibility of these events occurring cannot be eliminated entirely and there can be no
assurance that any measures we take will prevent cyber-attacks or security breaches that could adversely affect our business.

We have broad discretion in the use of our cash and may not use it effectively.

Our management has broad discretion in the use of our cash and may not apply our cash in ways that ultimately increases the value of any investment in our securities. We currently intend to use our
cash to fund marketing activities for any future commercialized products, to fund certain clinical trials for product candidates, to fund research and development activities for potential new product
candidates,  and  for  working  capital,  capital  expenditures  and  general  corporate  purposes.  As  in  the  past  we  expect  to  invest  our  excess  cash  in  available-for-sale  marketable  securities,  including
corporate bonds, U.S. government securities, other fixed income securities and equities; and these investments may not yield a favorable return. If we do not invest or apply our cash effectively, our
financial position and the price of ADSs may decline.

We currently do not intend to pay dividends and cannot assure the holders of our ADSs that we will make dividend payments in the future.

We have never declared or paid a cash dividend on any of our ordinary shares or ADSs and do not anticipate declaring cash dividends in the foreseeable future. Declaration of dividends will depend
upon, among other things, future earnings, if any, the operating and financial condition of our business, our capital requirements, general business conditions and such other factors as our Board of
Directors deems relevant.

Our effective tax rate could be highly volatile and could adversely affect our operating results.

Our future effective tax rate may be adversely affected by a number of factors, many of which are outside of our control, including:

•

the jurisdictions in which profits are determined to be earned and taxed;

-55-

•
•
•
•
•
•

changes in the valuation of our deferred tax assets and liabilities;
changes in share-based compensation expense;
changes in domestic or international tax laws or the interpretation of such tax laws;
changes in available tax credits;
adjustments to estimated taxes upon finalization of various tax returns; and
the resolution of issues arising from tax audits with various tax authorities.

Any significant increase in our future effective tax rates could impact our results of operations for future periods adversely.

Changes in tax law could adversely affect our business and financial condition.

We are subject to income and other taxes in the U.S. and foreign jurisdictions. Changes to applicable U.S. or foreign tax laws and regulations, or their interpretation and application (which changes
may have retroactive application), including with respect to net operating losses and research and development tax credits, could adversely affect us or holders of our ordinary shares or ADSs. In
recent years, many such changes have been made and changes are likely to continue to occur in the future. Future changes in tax laws could have a material adverse effect on our business, cash flow,
financial condition or results of operations. We urge investors to consult with their legal and tax advisors regarding the implications of potential changes in tax laws on an investment in our ordinary
shares or ADSs.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of December 31, 2021, we had $74,406 of net operating losses in the U.S. Of the $74,406 of net operating losses in the U.S., $10,365 were acquired due to the acquisition of FSC Therapeutics and
FSC Laboratories, Inc., (collectively “FSC”) and $64,041 are due to the losses at Avadel US Holdings, Inc. The portion due to the acquisition of FSC will expire in 2034 through 2035. The U.S. net
operating losses acquired as part of the acquisition of FSC are subject to an annual limitation under Internal Revenue Code Section 382 and $1,473 of the $10,365 will not be fully utilized before they
expire. The remaining $64,041 of net operating losses do not have an expiration date.

Under U.S. federal tax legislation enacted in 2017, informally titled the Tax Cuts and Jobs Act (“Tax Act”), U.S. federal net operating losses incurred in 2018 and in future years may be carried
forward indefinitely, but the deductibility of such U.S. federal net operating losses is limited. Under Sections 382 and 383 of the U.S. Internal Revenue Code of 1986 (the “Code”) if a corporation
undergoes an “ownership change” (generally defined as a greater than 50 percentage-point cumulative change (by value) in the equity ownership of certain shareholders over a rolling three-year
period), the corporation’s ability to use its pre-change net operating losses and other pre-change tax attributes to offset its post-change taxable income or taxes may be limited. We may also experience
ownership changes as a result of this offering or future issuances of our stock or as a result of subsequent shifts in our stock ownership, some of which are outside our control. We have completed an
analysis to determine that no events have been triggered in the past. If any ownership changes are determined to be triggered in the future, our ability to use our current net operating losses to offset
post-change taxable income or taxes would be subject to limitation. We will be unable to use our net operating losses if we do not attain profitability sufficient to offset our available net operating
losses prior to their expiration.

As of December 31, 2021, we had approximately $124,720 of net operating losses in Ireland that do not have an expiration date. While these losses do not have an expiration date, substantial changes
in the activities performed in these jurisdictions could have an impact on our ability to utilize these tax attributes in the future.

-56-

U.S. Holders of ordinary shares or ADSs may suffer adverse U.S. tax consequences if we are classified as a passive foreign investment company.

Generally, if, for any taxable year, at least 75% of our gross income is passive income, or at least 50% of the value of our assets is attributable to assets that produce passive income or are held for the
production of passive income, including cash, we would be characterized as a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes. For purposes of these tests, passive
income  includes  dividends,  interest,  and  gains  from  the  sale  or  exchange  of  investment  property  and  rents  and  royalties  other  than  rents  and  royalties  that  are  received  from  unrelated  parties  in
connection with the active conduct of a trade or business. Our status as a PFIC depends on the composition of our income and the composition and value of our assets (for which purpose the total
value of our assets may be determined in part by the market value of the ordinary shares or ADSs, which are subject to change) from time to time. If we are characterized as a PFIC, U.S. Holders (as
defined  below  under  “Material  U.S.  Federal  Income  Tax  Considerations  for  U.S.  Holders”)  of  ordinary  shares  or  ADSs  may  suffer  materially  adverse  tax  consequences,  including  having  gains
realized on the sale of ordinary shares or ADSs treated as ordinary income, rather than capital gain, the loss of the preferential rate applicable to dividends received on ordinary shares or ADSs by
individuals who are U.S. Holders, and having interest charges apply to distributions by us and the proceeds of sales of ordinary shares or ADSs.

We believe that we were not a PFIC for the taxable year ending December 31, 2020 and, based on the expected value of our assets, including any goodwill, and the expected nature and composition
of our income and assets, we expect that we will be a PFIC for our current taxable year. However, our status as a PFIC is a fact-intensive determination subject to various uncertainties, and we cannot
provide any assurances regarding our PFIC status for the current, prior or future taxable years.

Certain U.S. Holders that own 10 percent or more of the vote or value of ordinary shares or ADSs may suffer adverse U.S. tax consequences because our non-U.S. subsidiaries are expected to be
classified as controlled foreign corporations.

Each ‘‘Ten Percent Shareholder’’ (as defined below) in a non-U.S. corporation that is classified as a ‘‘controlled foreign corporation,’’ or a CFC, for U.S. federal income tax purposes generally is
required to include in income for U.S. federal tax purposes such Ten Percent Shareholder’s pro rata share of the CFC’s ‘‘Subpart F income’’ and investment of earnings in U.S. property, even if the
CFC has made no distributions to its shareholders. Subpart F income generally includes dividends, interest, rents, royalties, ‘‘global intangible low-taxed income,’’ gains from the sale of securities
and income from certain transactions with related parties. In addition, a Ten Percent Shareholder that realizes gain from the sale or exchange of shares in a CFC may be required to classify a portion
of such gain as dividend income rather than capital gain. A non-U.S. corporation generally will be classified as a CFC for U.S. federal income tax purposes if Ten Percent Shareholders own, directly
or indirectly, more than 50% of either the total combined voting power of all classes of stock of such corporation entitled to vote or of the total value of the stock of such corporation. A ‘‘Ten Percent
Shareholder’’ is a U.S. person (as defined by the Code) who owns or is considered to own 10% or more of the total combined voting power of all classes of stock entitled to vote or 10% or more of
the total value of all classes of stock of such corporation.

We believe that we were not a CFC in the 2021 taxable year, but that our non-U.S. subsidiaries were CFCs in the 2021 taxable year. We anticipate that our non-U.S. subsidiaries will remain CFCs in
the 2021 taxable year, and it is possible that we may become a CFC in the 2022 taxable year or in a subsequent taxable year. The determination of CFC status is complex and includes attribution
rules,  the  application  of  which  is  not  entirely  certain.  U.S.  Holders  should  consult  their  own  tax  advisors  with  respect  to  the  potential  adverse  U.S.  tax  consequences  of  becoming  a  Ten  Percent
Shareholder in a CFC, including the possibility and consequences of becoming a Ten Percent Shareholder in one or more of our non-U.S. subsidiaries that are anticipated to be treated as CFCs. If we
are classified as both a CFC and a PFIC, we generally will not be treated as a PFIC with respect to those U.S. Holders that meet the definition of a Ten Percent Shareholder during the period in which
we are a CFC, subject to certain exceptions.

We  incur  significant  costs  as  a  result  of  operating  as  a  public  company,  and  our  management  is  required  to  devote  substantial  time  to  compliance  requirements,  including  establishing  and
maintaining internal controls over financial reporting. We have identified a material weakness in our internal control over financial reporting. We may be exposed to potential risks if we are
unable to comply the requirements to maintain internal controls over financial reporting or if we identify additional material weaknesses.

As a public company in the United States organized, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and the listing rules of the
Nasdaq Stock Market ("Nasdaq"), and incur significant legal, accounting and other expenses to comply with applicable requirements. These rules impose various requirements on public companies,
including requiring certain corporate governance practices. Our management and other

-57-

 
personnel devote a substantial amount of time to these requirements. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time-
consuming and costly.

For example, the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act") requires, among other things, that we maintain effective internal controls for financial reporting and disclosure controls and
procedures. In particular, we must perform system and process evaluations and testing of our internal controls over financial reporting to allow management to report on the effectiveness of our
internal controls over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. Such compliance may require that we incur substantial accounting expenses and expend significant
management efforts.

During the Company’s fiscal 2021 financial statement close process, management identified a deficiency in the design of internal control over financial reporting related to its February 2023 Notes
indenture. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our
annual or interim financial statements will not be prevented or detected on a timely basis. Specifically, management did not have a control to identify that we were in technical default of the February
2023 Notes and owed 0.50% of additional interest on the February 2023 Notes due to not removing a restrictive legend from the February 2023 Notes 365 days following the original issuance of the
February 2023 Notes on February 16, 2018.

Once  the  material  weakness  was  identified,  we  developed  and  implemented  a  remediation  plan  that  includes  the  implementation  of  additional  control  procedures  surrounding  timely  and  period
evaluation of all terms of our debt agreement and the associated calculation of interest expense in accordance with the terms of such debt agreement to ensure the completeness and accuracy of the
calculation and timely payment of additional interest expense. Management is committed to maintaining a strong internal control environment and have fully implemented measures designed to help
ensure that the control deficiency contributing to the material weakness is remediated. However, there cannot be any assurance that these remediation efforts will be successful or that our internal
control over financial reporting will be effective as a result of these efforts. The material weakness will be fully remediated when, we have determined, through testing, these controls have operated
effectively for a sufficient period of time.

In the future we may determine that we have additional material weaknesses. Our failure to remediate the material weaknesses or failure to identify and address any other material weaknesses or
control deficiencies could result in inaccuracies in our financial statements and could also impair our ability to comply with applicable financial reporting requirements and related regulatory filings
on a timely basis, which could cause investors to lose confidence in our reported financial information, which may result in volatility in and a decline in the market price of our ADSs.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

We are subject to the periodic reporting requirements of the Exchange Act. We designed our disclosure controls and procedures to reasonably assure that information we must disclose in reports we
file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized and reported within the time periods specified in the rules and forms
of  the  SEC.  We  believe  that  any  disclosure  controls  and  procedures  or  internal  controls  and  procedures,  no  matter  how  well-conceived  and  operated,  can  provide  only  reasonable,  not  absolute,
assurance that the objectives of the control system are met. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of
simple  error  or  mistake.  Additionally,  controls  can  be  circumvented  by  the  individual  acts  of  some  persons,  by  collusion  of  two  or  more  people  or  by  an  unauthorized  override  of  the  controls.
Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

If securities analysts do not publish research or reports about our business or if they publish negative evaluations of our stock, the price of our stock could decline.

The trading market for our common stock relies in part on the research and reports that industry or financial analysts publish about us or our business. We do not have control over these analysts.
There can be no assurance that existing analysts will continue to provide research coverage or that new analysts will begin to provide research coverage. Although we have obtained analyst coverage,
if one or more of the analysts covering our business downgrade their evaluations of our stock, the price of our stock could decline. If one or more of these analysts cease to cover our stock, we could
lose visibility in the market for our stock, which in turn could cause our stock price to decline.

A transfer of ordinary shares may be subject to Irish stamp duty.

Transfers of ordinary shares (as opposed to ADSs) could be subject to Irish stamp duty (currently at the rate of 1% of the higher of the price paid or the market value of the shares acquired). Payment
of Irish stamp duty is generally a legal obligation of the transferee. Although transfers of ADSs are not subject to Irish stamp duty, the potential for stamp duty to arise on transfers of ordinary shares
could adversely affect the price of our ordinary shares or ADSs.

Overview 

Nature of Operations

Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is a biopharmaceutical company. Our lead product candidate, FT218, is an investigational once-nightly,
extended-release formulation of sodium oxybate for the treatment of excessive daytime sleepiness (“EDS”) or cataplexy in adults with narcolepsy. We are primarily focused on the development and
potential  United  States  (“U.S.”)  Food  and  Drug  Administration  (“FDA”)  approval  of  FT218.  In  December  2020,  we  submitted  a  New  Drug  Application  (“NDA”)  to  the  FDA  for  FT218  to  treat
excessive daytime sleepiness or cataplexy in adults with narcolepsy. In February 2021, the NDA for FT218 was accepted by the FDA and was assigned a Prescription Drug User Fee Act (“PDUFA”)
target action date of October 15, 2021. On October 15, 2021, we announced that the FDA informed us that the review of our NDA for FT218 was ongoing beyond its previously assigned target action
date. As of the date of this Annual Report, the FDA’s review of our NDA for FT218 remains ongoing.

Outside of our lead product candidate, we continue to evaluate opportunities to expand our product portfolio. As of the date of this Annual Report, we do not have any approved or commercialized
products in our portfolio.
FT218

FT218  is  a  once-nightly  formulation  of  sodium  oxybate  that  uses  our  Micropump  controlled  release  drug-delivery  technology  for  the  treatment  of  EDS  or  cataplexy  in  adults  suffering  from
narcolepsy. Sodium oxybate is the sodium salt of gamma hydroxybutyrate, an endogenous compound and metabolite of the neurotransmitter gamma-aminobutyric acid. Immediate release sodium
oxybate is approved in the U.S. for the treatment of EDS or cataplexy in patients with narcolepsy and is approved in Europe for the treatment of cataplexy in patients with narcolepsy. Since 2002,
sodium oxybate has only been available as a formulation that must be taken twice nightly, first at bedtime, and then again 2.5 to 4 hours later.

On December 16, 2020, we announced the submission of our NDA to the FDA for FT218. On February 26, 2021, the FDA notified us of formal acceptance of the NDA and assigned a PDUFA target
action date of October 15, 2021. On October 15, 2021, we announced that the FDA informed us that the review of our NDA for FT218 was ongoing beyond its previously assigned target action date.
As of the date of this Annual Report, the FDA’s review of our NDA for FT218 remains ongoing.

We conducted a Phase 3 clinical trial of FT218, the REST-ON trial, which was a randomized, double-blind, placebo-controlled study that enrolled 212 patients who received at least one dose of
FT218 or placebo, and was conducted in clinical sites in the U.S., Canada, Western Europe and Australia. The last patient, last visit was completed at the end of the first quarter of 2020, and positive
top  line  data  from  the  REST-ON  trial  was  announced  on  April  27,  2020.  Patients  who  received  9  g  of  once-nightly  FT218,  the  highest  dose  administered  in  the  trial,  demonstrated  statistically
significant and clinically meaningful improvement compared to placebo across the three co-primary endpoints of the trial: maintenance of wakefulness test (“MWT”), clinical global impression-
improvement (“CGI-I”), and mean weekly cataplexy attacks. The lower doses assessed, 6 g and 7.5 g also demonstrated statistically significant and clinically meaningful improvement on all three co-
primary endpoints compared to placebo. We observed the 9 g dose of once-nightly FT218 to be generally well tolerated. Adverse reactions commonly associated with sodium oxybate were observed
in a small number of patients (nausea 1.3%, vomiting 5.2%, decreased appetite 2.6%, dizziness 5.2%, somnolence 3.9%, tremor 1.3% and enuresis 9%), and 3.9% of the patients who received 9 g of
FT218 discontinued the trial due to adverse reactions.

In  January  2018,  the  FDA  granted  FT218  orphan  drug  designation  for  the  treatment  of  narcolepsy,  which  makes  FT218  potentially  eligible  for  certain  development  and  commercial  incentives,
including  potential  U.S.  market  exclusivity  for  up  to  seven  years.  Additionally,  several  FT218-related  U.S.  patents  have  been  issued,  and  there  are  additional  patent  applications  currently  in
development and/or pending at the U.S. Patent and Trademark Office (“USPTO”), as well as foreign patent offices.

In July 2020, we announced that the first patient was dosed in our open-label extension (“OLE”)/switch study of FT218 as a potential treatment for EDS or cataplexy in patients with narcolepsy. The
OLE/switch study is examining the long-term safety and maintenance of efficacy of FT218 in patients with narcolepsy who participated in the REST-ON study, as well as dosing and preference data
for patients switching from twice-nightly sodium oxybate to once-nightly FT218, regardless of whether they participated in REST-ON. In May 2021, inclusion criteria were expanded to allow for
oxybate naïve patients to enter the study.

New secondary endpoints from the REST-ON trial were presented at the American Academy of Neurology, beginning April 17, 2021. The first poster described FT218 improvements in disturbed
nocturnal sleep (“DNS”), defined in REST-ON as the

-64-

number of shifts from stages N1, N2, N3, and rapid eye movement (“REM”) sleep to wake and from stages N2, N3, and REM sleep to stage N1. FT218 also decreased the number of nocturnal
arousals as measured on polysomnography. Improvements in DNS were further supported by post-hoc analyses demonstrating increased time in deep sleep (N3, also known as slow wave sleep), and
less time in N1. A second poster described the statistically significant improvements in the Epworth Sleepiness Scale, both the quality of sleep and the refreshing nature of sleep, and a decrease in
sleep  paralysis.  These  clinically  relevant  improvements  were  observed  for  all  doses,  beginning  at  week  3,  for  the  lowest  6  g  dose,  compared  to  placebo.  FT218  did  not  demonstrate  significant
improvement for hypnagogic hallucinations compared to placebo.

Additional data supportive of the efficacy findings in REST-ON were presented at the 35th Annual Meeting of the Associated Professional Sleep Societies, a joint meeting of the American Academy
of Sleep Medicine and the Sleep Research Society, also known as SLEEP 2021, beginning June 10, 2021. New data included post-hoc analyses demonstrating endpoints improvements, regardless of
concomitant stimulant use, in both narcolepsy Type 1 or Type 2. Additionally, a post-hoc analysis showed that FT218 was associated with decreased body mass index compared to placebo, which
may be relevant as people with narcolepsy often have co-morbid obesity. In August 2021, the primary results from the REST-ON trial were published by Kushida et al. in the journal SLEEP. New
data was presented at the American College of Chest Physicians annual meeting, beginning October 17, 2021, including additional post-hoc analyses from the REST-ON trial, demonstrating a greater
proportion of patients receiving FT218 experienced reductions in weekly cataplexy attacks and improvement in mean sleep latency compared to placebo, as well as the results of a discrete choice
experiment, indicating that the overall driver of patient preference between sodium oxybate treatments is a once-nightly, versus twice-nightly, formulation.

We believe FT218 has the potential to demonstrate improved dosing compliance, safety and patient satisfaction over the current standards of care for EDS or cataplexy in patients with narcolepsy,
which are twice-nightly oxybate formulations.

Micropump Drug-Delivery Technology

Our Micropump drug-delivery technology allows for the controlled delivery of small molecule drugs taken orally, which has the potential to improve dosing compliance, reduce toxicity and improve
patient  compliance.  Beyond  FT218,  we  believe  there  could  be  other  product  development  opportunities  for  our  Micropump  drug-delivery  technology,  representing  either  life  cycle  opportunities,
whereby additional intellectual property can be added to a pharmaceutical product to extend the commercial viability of a currently marketed product, or innovative formulation opportunities for new
chemical entities.

Previously Approved FDA Products

On  June  30,  2020  (“Closing  Date”),  we  announced  the  sale  of  our  portfolio  of  sterile  injectable  drugs  used  in  the  hospital  setting  (the  “Hospital  Products”),  including  our  three  FDA-approved
commercial products, Akovaz, Bloxiverz and Vazculep, as well as Nouress, to Exela Sterile Medicines LLC (“Exela Buyer”).

Key Business Trends and Highlights 

In operating our business and monitoring our performance, we consider a number of performance measures, as well as trends affecting our industry as a whole, which include the following: 

• Healthcare and Regulatory Reform: Various health care reform laws in the U.S. may impact our ability to successfully commercialize our products and technologies. The success of our
commercialization efforts may depend on the extent to which the government health administration authorities, the health insurance funds in the E.U. Member States, private health insurers
and other third-party payers in the U.S. will reimburse consumers for the cost of healthcare products and services.

• Competition and Technological Change: Competition in the pharmaceutical and biotechnology industry continues to be intense and is expected to increase. We compete with academic
laboratories,  research  institutions,  universities,  joint  ventures,  and  other  pharmaceutical  and  biotechnology  companies,  including  other  companies  developing  niche  branded  or  generic
specialty pharmaceutical products or drug delivery platforms. Furthermore, major technological changes can happen quickly in the pharmaceutical and biotechnology industries. Such rapid
technological change, or the development by our competitors of technologically improved or differentiated products, could render our products, product candidates, or drug delivery platforms
obsolete or noncompetitive.

-65-

•

Pricing Environment for Pharmaceuticals: The pricing environment continues to be in the political spotlight in the U.S. As a result, the need to obtain and maintain appropriate pricing for
pharmaceutical  products  may  become  more  challenging  due  to,  among  other  things,  the  attention  being  paid  to  healthcare  cost  containment  and  other  austerity  measures  in  the  U.S.  and
worldwide.

• Generics  Playing  a  Larger  Role  in  Healthcare:  Generic  pharmaceutical  products  will  continue  to  play  a  large  role  in  the  U.S.  healthcare  system.  As  such,  we  expect  to  see  generic

competition for our products in the future.

• Access to and Cost of Capital: The process of raising capital and associated cost of such capital for a company of our financial profile can be difficult and potentially expensive. If the need

were to arise to raise additional capital, access to that capital may be difficult, expensive and/or dilutive and, as a result, could create liquidity challenges for the Company.

• Continuing Net Loss from Operations: We sold our Hospital Products on June 30, 2020 and no longer generate revenue. We expect to continue to incur operating losses for the foreseeable

future to continue our preparations for the commercial launch of FT218, if approved.

Impact of COVID-19

Since early 2020, we have seen the profound impact that the ongoing coronavirus (“COVID-19”) pandemic is having on human health, the global economy and society at large. We have continued to
actively monitor the COVID-19 pandemic and have taken measures to mitigate the potential impacts to our employees and business, such as continuing to offer a work from home policy. We believe
the  ongoing  impact  of  COVID-19  and  measures  to  prevent  its  spread  could  impact  our  business  in  a  number  of  ways,  including:  i)  possibly  delaying  our  ongoing  RESTORE  open-label
extension/switch study, ii) disruptions to our supply chain and third parties; iii) requiring our employees to work from home for an extended period of time; and iv) hindering sales efforts for FT218,
if approved. An extended period of global supply chain and economic disruption could materially affect our business, results of operations, access to sources of liquidity and financial condition.
Despite  progress  in  vaccination  efforts,  future  developments  and  impact  on  our  operations  remain  uncertain  and  cannot  be  predicted  with  confidence,  including  the  duration  of  the  COVID-19
pandemic,  new  variants  of  the  virus,  new  information  which  may  emerge  concerning  the  severity  of  the  COVID-19  pandemic,  and  any  additional  preventative  and  protective  actions  that
governments, or we, may direct, which may result in extending continued business disruptions.

Financial Highlights

Highlights of our consolidated results for the year ended December 31, 2021 are as follows: 

•

Revenue was $0 for the year ended December 31, 2021 compared to $22,334 in the same period last year. The year over year decrease was the result of the sale of the Hospital Products on
June 30, 2020.

• Operating loss was $85,546 for the year ended December 31, 2021 compared to operating income of $5,815 for the year ended December 31, 2020. Operating income for the year ended
December 31, 2020 was driven by the gain on sale of the Hospital Products on June 30, 2020 of $45,760. Selling, general & administrative expenses increased in the current year by $36,090,
driven by the Company’s continued commercial preparations and launch readiness activities for the potential approval of FT218.

• Net loss was $77,329 for the year ended December 31, 2021 compared to net income of $7,028 in the same period last year.

• Diluted net loss per share was $1.32 for the year ended December 31, 2021 compared to diluted net income per share of $0.13 in the same period last year.

•

Cash and marketable securities decreased by $64,181 to $157,221 at December 31, 2021 from $221,402 at December 31, 2020. This decrease was largely driven by $77,310 of cash used in
operations during the year ended December 31, 2021, partially offset by cash proceeds from the disposition of the Hospital Products of $16,500.

Critical Accounting Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to use judgment in making estimates and assumptions that affect the reported amounts of
assets  and  liabilities,  disclosures  of  contingent  assets  and  liabilities  at  the  date  of  the  consolidated  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during  the  periods
presented.

We have identified certain policies and estimates as critical to our business operations and the understanding of our past or present results of operations. These policies and estimates are considered
critical because they had a material impact, or they have the potential to have a material impact, on our consolidated financial statements and because they require us to make significant judgments,
assumptions or estimates. We believe that the estimates, judgments and assumptions made when accounting for the items described below were reasonable, based on information available at the time
they  were  made.  However,  actual  results  may  differ  from  those  estimates,  and  these  differences  may  be  material.  For  a  complete  list  of  significant  accounting  policies,  see  Note  1:  Summary  of
Significant Accounting Policies to our audited consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K.

Product Sales. Prior to June 30, 2020, revenue included sales of pharmaceutical products. We sold our products primarily through wholesalers and considered these wholesalers to be our customers.
Revenue from product sales is recognized when the customer obtains control of our product, which occurs typically upon receipt by the customer. Our gross product sales were subject to a variety of
price adjustments in arriving at reported net product sales.

The price adjustments contained estimates of product returns, chargebacks, payment discounts, rebates, and other sales allowances and were estimated based on analysis of historical data for the
product or comparable products, future expectations for such products and other judgments and analysis. The estimates were reviewed monthly and any adjustments were recognized as adjustments to
product sales in the period the adjustments were identified.

Any adjustments made were recognized as adjustments to product sales in the period that they were identified. We did not record any revenue from sales of pharmaceutical products in the year ended
December 31, 2021 nor recognize any adjustments to product sales from prior periods.

Research and Development (“R&D”). R&D expenses consist primarily of costs related to outside services, personnel expenses, clinical studies, and other R&D expenses. Clinical studies and outside
services costs relate primarily to services performed by clinical research organizations and related clinical or development manufacturing costs, materials and supplies, filing fees, regulatory support,
and other third-party fees. Personnel expenses relate primarily to salaries, benefits and share-based compensation. Other R&D expenses primarily include overhead allocations consisting of various
support and facilities-related costs. R&D expenditures are charged to operations as incurred. Raw materials used in the production of pre-clinical and clinical products are expensed as R&D costs.

We recognize refundable R&D tax credits received for spending on innovative R&D as an offset of R&D expenses.

When estimating R&D expense, we review open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level
of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers invoice us in
arrears  for  services  performed  and  some  require  advanced  payments.  We  make  estimates  of  our  accrued  expenses  at  each  balance  sheet  date  in  our  financial  statements  based  on  facts  and
circumstances known to us at that time.

If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or amount of prepaid or accrued expenses accordingly. To date, we have not
made any material adjustments to our prior estimates of accrued research and development expenses.

Share-based Compensation. We account for share-based compensation based on the estimated grant-date fair value. The fair value of stock options is estimated using Black-Scholes option-pricing
valuation models (“Black-Scholes model”). We recognize compensation cost, net of an estimated forfeiture rate, using the accelerated method over the requisite service period of the award.

As required by the Black-Scholes model, estimates are made of the underlying volatility of Avadel stock, a risk-free rate determined by reference to the U.S. Treasury yield curve, and an expected
term of the option. We estimate the expected term using a simplified method, as we do not have enough historical exercise data for a majority of such options upon which to estimate an expected
term.

-67-

 
Changes in the estimates used to determine the fair value of share-based equity compensation instruments could result in changes to our share-based compensation expense. We have not made any
material changes to our assumptions and estimates related to our share-based compensation during the periods presented. Individual assumptions are not sensitive to change.

Income Taxes. Our income tax benefit, deferred tax assets and liabilities, and liabilities for unrecognized tax benefits reflect management’s best estimate of current and future taxes to be paid. We are
subject to income taxes in Ireland, France and the U.S. Significant judgments and estimates are required in the determination of the consolidated income tax benefit.

Deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, which will result in taxable or deductible
amounts  in  the  future.  In  evaluating  our  ability  to  recover  our  deferred  tax  assets  in  the  jurisdiction  from  which  they  arise,  we  consider  all  available  positive  and  negative  evidence,  including
scheduled reversals of deferred tax liabilities, projected future taxable income or loss, tax-planning strategies, and results of recent operations. The assumptions about future taxable income or loss
require the use of significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across our global operations. A tax benefit
from  an  uncertain  tax  position  may  be  recognized  when  it  is  more  likely  than  not  that  the  position  will  be  sustained  upon  examination,  including  resolutions  of  any  related  appeals  or  litigation
processes, on the basis of the technical merits.

We record unrecognized tax benefits as liabilities and adjust these liabilities when our judgment changes as a result of the evaluation of new information not previously available. Because of the
complexity  of  some  of  these  uncertainties,  the  ultimate  resolution  may  result  in  a  payment  that  is  materially  different  from  our  current  estimate  of  the  unrecognized  tax  benefit  liabilities.  These
differences will be reflected as increases or decreases to income tax expense in the period in which new information is available.

We have not recorded a deferred tax liability for any income or withholding taxes that may arise as the result of the distribution of unremitted earnings within our Company. As of December 31, 2021,
we had unremitted earnings of $3,916 outside of Ireland as measured on a U.S. GAAP basis. Based on our estimates that future domestic cash generation will be sufficient to meet future domestic
cash needs along with our specific plans for reinvestment, we have not recorded a deferred tax liability for any income or withholding taxes that may arise from a distribution that would qualify as a
dividend for tax purposes. It is not practicable to estimate the amount of deferred tax liability on such remittances, if any. We believe that our estimates for deferred income taxes and the amount of
benefits recognized for uncertain tax positions are appropriate based on current facts and circumstances.

Goodwill. Goodwill represents the excess of the acquisition consideration over the fair value of assets acquired and liabilities assumed. We have determined that we operate in a single segment and
have a single reporting unit associated with the development and commercialization of pharmaceutical products. We can test for goodwill impairment by first performing a qualitative assessment to
determine whether a quantitative goodwill test is necessary or we can elect to forgo the qualitative assessment and perform the quantitative test. We elected to perform a quantitative impairment
assessment of goodwill in 2021 and 2020. Upon performing the quantitative test, if the carrying value of the reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal
to that excess, not to exceed the carrying amount of goodwill. We have elected to make November 30 the annual impairment assessment date for goodwill. However, we could be required to evaluate
the  recoverability  of  goodwill  outside  of  the  required  annual  assessment  if,  among  other  things,  we  experience  disruptions  to  the  business,  unexpected  significant  declines  in  operating  results,
divestiture of a significant component of the business or a sustained decline in market capitalization.

When  performing  the  quantitative  assessment  of  goodwill  impairment,  we  estimate  the  fair  value  of  our  single  reporting  unit  using  the  market  approach,  based  on  quoted  market  prices  of  our
securities on the Nasdaq Global Market, adjusted for the effect of a control premium as contemplated by ASC 350. Based on the results of the annual quantitative evaluation for 2021, the fair value of
our single reporting unit exceeded its respective carrying value and did not result in impairment for the reporting unit.

The  Company  continuously  monitors  for  events  and  circumstances  that  could  negatively  impact  the  key  assumptions  in  determining  fair  value.  While  the  Company  believes  the  judgments  and
assumptions used in the goodwill impairment test is reasonable, different assumptions or changes in general industry, market and macro-economic conditions, including a more prolonged and/or
severe COVID-19 pandemic, could change the estimated fair values and, therefore, future impairment charges could be required, which could be material to the consolidated financial statements.

by the Company’s continued commercial preparations and launch readiness activities for potential approval of FT218. These activities included an increase in marketing and market research costs of
approximately $12,700 and an increase in other launch planning and preparation activities totaling $5,000. Compensation costs increased by approximately $11,000 due to an increase in headcount,
primarily in commercial and medical affairs. Legal, technology and insurance costs increased by approximately $7,200.

In 2021, the income tax benefit increased by $3,706 when compared to the same period in 2020. The increase in the income tax benefit in 2021 was primarily driven by the additional tax benefit from
an increase in the net operating losses in the U.S. in 2021, when compared to the same period in 2020. This was partially offset by the nonrecurring nature of tax benefits

Liquidity and Capital Resources 

Overview of Sources and Uses of Cash

We have had no revenue from product sales since the sale of our Hospital Products on June 30, 2020. We expect to continue to incur operating losses for the foreseeable future to further the clinical
development  of  and  continue  our  preparations  for  the  commercial  launch  of  FT218,  if  approved.  As  a  result,  we  may  need  to  raise  additional  capital  to  support  commercial  launch  of  FT218,  if
approved, and the continued growth of Avadel. At December 31, 2021, we held cash and marketable securities of $157,221 that will be used satisfy any cash requirements that we will have during the
twelve months ended December 31, 2022.

For the 12 month period ending December 31, 2022, we project that our fixed commitments will include (i) capital commitments, (ii) interest on our 2023 Notes, and (iii) lease payments. We project
that our long-term fixed commitments will include (i) capital commitments, (ii) interest on and repayment of principal of our 2023 Notes, and (iii) lease payments.

Capital Commitments  

At December 31, 2021, we have one commitment with our primary contract manufacturer related to facility upgrades and the purchase and validation of equipment to be used in the manufacture of
FT218. The total cost of this commitment is estimated to be approximately $5,500 and is expected to be completed during the year ending December 31, 2022. We incurred approximately $3,348 of
this commitment during the year ended December 31, 2021.

We also have a commitment with another contract manufacturer that commences in the first quarter of 2022 and will continue until FDA approval of the contract manufacturer. The commitment will
be approximately $3,000 per year.

Debt Arrangements

For the twelve month period ending December 31, 2022, we will pay interest on our 2023 Notes of $8,694. For the twelve month period ending December 31, 2023, we will pay interest on our 2023
Notes of $3,234 and principal, upon maturity, of $143,750. On March 16, 2022, Avadel Finance Cayman Limited, a Cayman Islands exempted company and an indirect wholly-owned subsidiary of
the Company (the “Issuer”), executed an agreement to exchange $117,375 its 2023 Notes due February 1, 2023 for a new series of its Exchangeable Senior Notes due October 2, 2023 (the “October
2023 Notes”) (the “Exchange”). The remaining $26,375 aggregate principal amount of the February 2023 Notes will maintain a maturity date of February 1, 2023. See Note 11: Long-Term Debt and
Note 23: Subsequent Events to our audited consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K for further details.

Operating Leases

At December 31, 2021, we have leases for office space and a production suite. We have a current obligation of $974 due within one year and a long-term obligation of $1,833 due between January 1,
2023 and December 31, 2025. See Note 10: Leases to our audited consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K for further details for further
details.

Operating Activities 

Net cash used in operating activities of $77,310 for the year ended December 31, 2021 increased from net cash used in operating activities of $48,734 in the prior year. Net cash used in operating
activities for the year ended December 31, 2021 was driven by net loss of $77,329 and unfavorable non-cash adjustments of $3,676, offset by favorable changes in working capital of $3,695. For the
year ended December 31, 2020, net cash used in operating activities was driven by net income of $7,028 and favorable non-cash adjustments of $4,322, offset by the $45,760 gain recorded for the
sale of the Hospital Products and a $14,324 unfavorable change in working capital. The year over year change in working capital is driven by an increase in accounts payable and accrued expenses in
2021 as a result of the Company’s commercial preparations and launch readiness activities for potential approval of FT218.

Investing Activities 

Cash provided by investing activities was $56,929 for the year ended December 31, 2021 compared to cash used in investing activities of $69,721 in the same prior year period. Net cash provided by
investing activities for the year ended December 31, 2021 was driven by net proceeds from sales of marketable securities of $40,455 and proceeds of $16,500 received from the sale of the Hospital
Products. Net cash used in investing activities for the year ended December 31, 2020 was driven by net purchases of marketable securities of $95,123, partially offset by proceeds from the disposition
of the Hospital Products of $25,500.

Financing Activities 

Cash provided by financing activities was $263 for the year ended December 31, 2021 compared to cash provided by financing activities of $179,683 for the same prior year period. Cash provided
financing activities for the year ended December 31, 2021 related to proceeds from the issuance of ordinary shares related to employee equity awards. Cash provided by financing activities for the
year ended December 31, 2020 was driven by the February private placement that resulted in net proceeds of $60,570, the May public offering that resulted in net proceeds of $116,924, and proceeds
from the issuance of ordinary shares of $2,189 related to employee equity awards.

Risk Management 

The adequacy of our cash resources depends on the outcome of certain business conditions including the cost of our FT218 clinical development and commercial launch plans, our cost structure, and
other factors set forth in “Risk Factors” within Part I, Item 1A of this Annual Report on Form 10-K. To  complete  the  FT218  clinical  development  and  commercial  launch  plans  we  will  need  to
commit substantial resources, which could result in future losses or otherwise limit our opportunities or affect our ability to operate our business. Our assumptions concerning the outcome of certain
business conditions may prove to be wrong or other factors may adversely affect our business, and as a result we could exhaust or significantly decrease our available cash and marketable securities
balances which could, among other things, force us to raise additional funds and/or force us to reduce our expenses, either of which could have a material adverse effect on our business. Additionally,
we are unable to estimate the near or long term impact of COVID-19, which may have a material adverse impact on our business.

If available to us, raising additional capital may be accomplished through one or more public or private debt or equity financings, royalty financings or collaborations or partnering arrangements. Any
equity financing would be dilutive to our shareholders.

Cash, cash equivalent and marketable security balances as of December 31, 2021 and unused financing sources are expected to provide us with the flexibility to meet our liquidity needs in 2022,
including operating requirements related to the commercial launch of FT218.

Other Matters 

Litigation  

We  are  subject  to  potential  liabilities  generally  incidental  to  our  business  arising  out  of  present  and  future  lawsuits  and  claims  related  to  product  liability,  personal  injury,  contract,  commercial,
intellectual property, tax, employment, compliance and other matters that arise in the ordinary course of business. We accrue for potential liabilities when it is probable that future costs (including
legal fees and expenses) will be incurred and such costs can be reasonably estimated. At December 31, 2021 and December 31, 2020, there were no contingent liabilities with respect to any litigation,
arbitration or administrative or other proceeding that are reasonably likely to have a material adverse effect on our consolidated financial position, results of operations, cash flows or liquidity. For
information regarding legal proceedings we are involved in, see Note 15: Contingent

Liabilities and Commitments to our audited consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk.

Interest Rate Risk 

We  are  subject  to  interest  rate  risk  as  a  result  of  our  portfolio  of  marketable  securities.  The  primary  objectives  of  our  investment  policy  are  as  follows:  safety  and  preservation  of  principal  and
diversification of risk; liquidity of investments sufficient to meet cash flow requirements; and competitive yield. Although our investments are subject to market risk, our investment policy specifies
credit  quality  standards  for  our  investments  and  limits  the  amount  of  credit  exposure  from  any  single  issue,  issuer  or  certain  types  of  investment.  Our  investment  policy  allows  us  to  maintain  a
portfolio of cash equivalents and marketable securities in a variety of instruments, including U.S. federal government and federal agency securities, European Government bonds, corporate bonds or
commercial  paper  issued  by  U.S.  or  European  corporations,  money  market  instruments,  certain  qualifying  money  market  mutual  funds,  certain  repurchase  agreements,  tax-exempt  obligations  of
states, agencies, and municipalities in the U.S and Europe, and equities. 

Foreign Exchange Risk

We are exposed to foreign currency exchange risk as the functional currency financial statements of a non-U.S. subsidiary is translated to U.S. dollars. The assets and liabilities of this non-U.S.
subsidiary having a functional currency other than the U.S. dollar is translated into U.S. dollars at the exchange rate prevailing at the balance sheet date, and at the average exchange rate for the
reporting period for revenue and expense accounts. The cumulative foreign currency translation adjustment is recorded as a component of accumulated other comprehensive loss in shareholders’
equity.  The  reported  results  of  this  non-U.S.  subsidiary  will  be  influenced  by  their  translation  into  U.S.  dollars  by  currency  movements  against  the  U.S.  dollar.  Our  primary  currency  translation
exposure is related to one subsidiary that has functional currencies denominated in euro. A 10% strengthening/weakening in the rates used to translate the results of our non-U.S. subsidiaries that have
functional currencies denominated in euro as of December 31, 2021 would have had an immaterial impact on net loss for the year ended December 31, 2021.

Transactional exposure arises where transactions occur in currencies other than the functional currency. Transactions in foreign currencies are recorded at the exchange rate prevailing at the date of
the transaction. The resulting monetary assets and liabilities are translated into the appropriate functional currency at exchange rates prevailing at the balance sheet date and the resulting gains and
losses are reported in investment and other income (expense), net in the consolidated statements of (loss) income.  As of December 31, 2021, our primary exposure is to transaction risk related to euro
net monetary assets and liabilities held by subsidiaries with a U.S. dollar functional currency. Realized and unrealized foreign exchange gains resulting from transactional exposure were immaterial
for the year ended December 31, 2021.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(In thousands, except per share data)

NOTE 1: Summary of Significant Accounting Policies

Nature of Operations. Avadel Pharmaceuticals plc (Nasdaq: AVDL) (“Avadel,” the “Company,” “we,” “our,” or “us”) is a biopharmaceutical company. The Company is registered as an Irish public
limited company. The Company’s headquarters are in Dublin, Ireland with operations in St. Louis, Missouri, United States (“U.S”).

The  Company’s  lead  product  candidate,  FT218,  is  an  investigational  once-nightly,  extended-release  formulation  of  sodium  oxybate  for  the  treatment  of  excessive  daytime  sleepiness  (“EDS”)  or
cataplexy  in  adults  with  narcolepsy.  The  Company  is  primarily  focused  on  the  development  and  potential  United  States  (“U.S.”)  Food  and  Drug  Administration  (“FDA”)  approval  of  FT218.  In
December 2020, the Company submitted a New Drug Application (“NDA”) to the FDA for FT218 to treat excessive daytime sleepiness or cataplexy in adults with narcolepsy. In February 2021, the
NDA for FT218 was accepted by the FDA and was assigned a Prescription Drug User Fee Act (“PDUFA”) target action date of October 15, 2021. On October 15, 2021, the Company announced that
the FDA informed us that the review of the Company’s NDA for FT218 was ongoing beyond its previously assigned target action date. As of the date of this Annual Report, the FDA’s review of the
Company’s NDA for FT218 remains ongoing.

Outside of the Company’s lead product candidate, the Company continues to evaluate opportunities to expand its product portfolio. As of the date of this Annual Report, the Company does not have
any approved or commercialized products in its portfolio.
Basis of Presentation. These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”). The consolidated financial
statements include the accounts of the Company and all subsidiaries. All intercompany accounts and transactions have been eliminated. 

The Company’s results of operations for the period January 1, 2019 through February 6, 2019 include the results of Avadel Specialty Pharmaceuticals, LLC (“Specialty Pharma”) prior to its February
6, 2019 voluntary petition for reorganization under Chapter 11 of the U.S. Bankruptcy Code. See Note 3: Subsidiary Bankruptcy and Deconsolidation.

Reclassifications

Certain reclassifications are made to prior year amounts whenever necessary to conform with the current year presentation. Certain reclassifications have been made to the Consolidated Statements of
Cash Flows for the fiscal year ended December 31, 2019 and balances within Note 14: Other Assets and Liabilities for the year ended December 31, 2020 to condense line items of the same nature
into a single line. This change does not affect previously reported net cash flows used in operating activities in the Consolidated Statements of Cash Flows.

Out of Period Adjustments

In 2021, the Company determined that 0.50% of additional interest expense (the “Additional Interest”), as defined in the indenture dated as of February 16, 2018 among Avadel Finance Cayman Ltd,
Avadel Pharmaceuticals PLC, and The Bank of New York Mellon as trustee (the “Indenture”), was owed on its long term 4.50% exchangeable unsecured senior notes due 2023 (the “2023 Notes”)
from a period of February 17, 2019 through December 31, 2021, totaling $817, $773, and $635 for the years ended December 31, 2021, 2020 and 2019, respectively. At December 31, 2020, the
Company’s accrued interest was understated by $1,408. The Additional Interest resulted from not removing a restrictive legend from the 2023 Notes 365 days following their original issuance on
February 16, 2018. The  restrictive  legend  was  removed  in  March  2022  and  the  Additional  Interest  is  no  longer  applicable  following  the  date  of  removal  of  the  restrictive  legend.  The  Company
identified  and  recorded  an  out  of  period  adjustment  for  cumulative  amount  of  the  Additional  Interest  in  2021  of  $1,408.  Management  assessed  the  materiality  of  the  impact  of  the  out  of  period
adjustment on its financial statements, both quantitatively and qualitatively, and determined that it was not material for any quarterly or annual period.

The 2023 Notes were issued on February 16, 2018 (the “Original Issuance”) with a restrictive legend which remained in place until March 14, 2022. Per the terms of the Indenture, if the restrictive
legend on the 2023 Notes was not removed on the 365th day following the original issuance of the 2023 Notes, the Company owed Additional Interest, payable on each of the semi-annual interest
payment  dates  of  February  1  and  August  1  beginning  August  1,  2019  and  each  of  the  semi-annual  payment  dates  thereafter  until  the  restrictive  legend  was  removed.  The  non-payment  of  the
Additional Interest expense on the semi-annual

-79-

payment dates, which was first due beginning August 1, 2019, is defined as an “Event of Default” in the Indenture, causing the Company to be in technical default of its 2023 Notes until the default
was cured. The Additional Interest was paid to the trustee on March 10, 2022, which under the terms of the indenture, management believes cured the Event of Default for all periods. Additionally, on
March 14, 2022, the restrictive legend on the 2023 Notes was removed and the Company is not subject to the Additional Interest after that date. Had the Company identified and been unable to cure
the technical default prior to the issuance of its financial statements for fiscal years 2020 and 2019, it could have resulted in the reclassification of the long-term principal balance of 2023 Notes
reported in those periods. As a result of curing the technical default, the Company classified the 2023 Notes as long-term at December 31, 2021 and 2020. The Indenture is included as Exhibit 4.2 to
this Annual Report on Form 10-K.

Revenue. Prior to June 30, 2020, revenue included sales of pharmaceutical products, licensing fees, and, if any, milestone payments for research and development (“R&D”) achievements.

To determine the appropriate revenue recognition, the Company performs the following five steps: (i) Identify the contract(s) with a customer; (ii) Identify the performance obligations in the contract;
(iii)  Determine  the  transaction  price;  (iv)  Allocate  the  transaction  price  to  the  performance  obligations  in  the  contract;  and  (v)  Recognize  revenue  when  (or  as)  the  entity  satisfies  a  performance
obligation. The Company applies the five-step model to contracts only when the Company and its customer’s rights and obligations under the contract can be determined, the contract has commercial
substance, and it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. The Company identifies the promised
goods  or  services  in  the  contract  to  determine  if  they  are  separate  performance  obligations  or  if  they  should  be  bundled  with  other  goods  and  services  into  a  single  performance  obligation.  The
Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

Product Sales  

Prior to June 30, 2020, the Company sold products primarily through wholesalers and considered these wholesalers to be the Company’s customers. Revenue from product sales is recognized when
the customer obtains control of the Company’s product, which occurs typically upon receipt by the customer. The Company’s gross product sales were subject to a variety of price adjustments in
arriving  at  reported  net  product  sales.  These  adjustments  included  estimates  of  product  returns,  chargebacks,  payment  discounts,  rebates,  and  other  sales  allowances  and  are  estimated  based  on
analysis of historical data for the product or comparable products, future expectations for such products and other judgments and analysis.  

Research  and  Development  (“R&D”).  R&D  expenses  consist  primarily  of  costs  related  to  outside  services,  personnel  expenses,  clinical  studies  and  other  R&D  expenses.  Outside  services  and
clinical studies costs relate primarily to services performed by clinical research organizations and related clinical or development manufacturing costs, materials and supplies, filing fees, regulatory
support, and other third-party fees. Personnel expenses relate primarily to salaries, benefits and share-based compensation. Other R&D expenses primarily include overhead allocations consisting of
various support and facilities-related costs. R&D expenditures are charged to operations as incurred. Raw materials used in the production of pre-clinical and clinical products are expensed as R&D
costs.  

The Company recognizes refundable R&D tax credits received for spending on innovative R&D as an offset of R&D expenses.  
Advertising Expenses. The Company expenses the costs of advertising as incurred. Branded advertising expenses were $0, $312 and $372 for the years ended December 31, 2021, 2020 and 2019,
respectively.

Share-based Compensation. The  Company  accounts  for  share-based  compensation  based  on  the  estimated  grant-date  fair  value.  The  fair  value  of  stock  options  is  estimated  using  Black-Scholes
option-pricing valuation models (“Black-Scholes model”). As required by the Black-Scholes model, estimates are made of the underlying volatility of Avadel stock, a risk-free rate and an expected
term of the option or warrant. The Company estimates the expected term using a simplified method, as the Company does not have enough historical exercise data for a majority of such options upon
which to estimate an expected term. The Company recognizes compensation cost, net of an estimated forfeiture rate, using the accelerated method over the requisite service period of the award.

Income  Taxes.  The  Company  accounts  for  income  taxes  under  the  asset  and  liability  method,  which  requires  the  recognition  of  deferred  tax  assets  and  liabilities  for  the  expected  future  tax
consequences of events that have been included in the financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the
financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which

-80-

the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

The Company recognizes deferred tax assets to the extent that the Company believes that these assets are more likely than not to be realized. In making such a determination, the Company considers
all  available  positive  and  negative  evidence,  including  future  reversals  of  existing  taxable  temporary  differences,  projected  future  taxable  income,  tax-planning  strategies,  and  results  of  recent
operations. If the Company determines that it would be able to realize its deferred tax assets in the future in excess of their net recorded amount, the Company would make an adjustment to the
deferred tax asset valuation allowance, which would reduce the provision for income taxes.

The Company records uncertain tax positions on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the
basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is
more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

The Company recognizes interest and penalties related to unrecognized tax benefits in the income tax expense line in the consolidated statements of (loss) income. Accrued interest and penalties are
included on the related tax liability line in the consolidated balance sheets.

Cash and Cash Equivalents. Cash and cash equivalents consist of cash on hand, cash on deposit and fixed term deposits which are highly liquid investments with original maturities of less than three
months.  

Marketable  Securities.  The  Company’s  marketable  securities  are  considered  to  be  available  for  sale  and  are  carried  at  fair  value,  with  unrealized  gains  and  losses,  net  of  taxes,  reported  as  a
component of accumulated other comprehensive (loss) income (“AOCI”) in shareholders’ equity, with the exception of unrealized gains and losses on equity instruments and allowances for expected
credit losses, if any, which are reported in earnings in the current period. The cost of securities sold is based upon the specific identification method.  

For available-for-sale debt securities in an unrealized loss position, the Company assesses whether it intends to sell 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. If the criteria are not
met, the Company evaluates whether the decline in fair value has resulted from a credit loss or other factors. In making this assessment, management considers, among other factors, the extent to
which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security. If this assessment indicates that a
credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of the cash flows expected to
be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized
costs basis.

Allowance for Credit Losses. Amounts owed to the Company are presented net of an allowance that includes as assessment of expected credit losses. An allowance for credit losses is established
based  on  expected  losses.  Expected  losses  are  estimated  by  reviewing  individual  accounts,  considering  aging,  financial  condition  of  the  debtor,  payment  history,  current  and  forecast  economic
conditions  and  other  relevant  factors.  To  the  extent  that  the  Company  identifies  that  any  individual  customer's  credit  quality  has  deteriorated,  the  Company  establishes  allowances  based  on  the
individual risk characteristics of that customer. The Company makes concerted efforts to collect all outstanding balances due from customers; however, amounts are written off against the allowance
when the related balances are no longer deemed collectible

Property  and  Equipment. Property  and  equipment  is  stated  at  historical  cost  less  accumulated  depreciation.  Depreciation  and  amortization  are  computed  using  the  straight-line  method  over  the
following estimated useful lives:
Software, office and computer equipment
Leasehold improvements, furniture, fixtures and fittings

3 years
5-10 years

Goodwill. Goodwill  represents  the  excess  of  the  acquisition  consideration  over  the  fair  value  of  assets  acquired  and  liabilities  assumed.  The  Company  has  determined  that  it  operates  in  a  single
segment and have a single reporting unit associated with the development and commercialization of pharmaceutical products. The Company tests goodwill for impairment annually and when events
or changes in circumstances indicate that the carrying value may not be recoverable. The Company determined that no impairment of goodwill existed at December 31, 2021 and 2020.

-81-

 
Long-Lived  Assets.  Long-lived  assets  include  fixed  assets  and  intangible  assets.  Prior  to  the  sale  of  the  Company’s  portfolio  of  sterile  injectable  drugs  used  in  the  hospital  setting  (“Hospital
Products”) on June 30, 2020, intangible assets consisted primarily of purchased licenses and intangible assets recognized as part of the Éclat Pharmaceuticals acquisition. Acquired in-process research
and  development  (“IPR&D”)  had  an  indefinite  life  and  was  not  amortized  until  completion  and  development  of  the  project,  at  which  time  the  IPR&D  became  an  amortizable  asset,  for  which
amortization of such intangible assets was computed using the straight-line method over the estimated useful life of the assets.  

Long-lived assets are reviewed for impairment whenever conditions indicate that the carrying value of the assets may not be fully recoverable. Such impairment tests are based on a comparison of the
pretax undiscounted cash flows expected to be generated by the asset to the recorded value of the asset or other market-based value approaches. If impairment is indicated, the asset value is written
down  to  its  market  value  if  readily  determinable  or  its  estimated  fair  value  based  on  discounted  cash  flows.  Any  significant  changes  in  business  or  market  conditions  that  vary  from  current
expectations could have an impact on the fair value of these assets and any potential associated impairment. On June 30, 2020, the Company transferred its remaining intangible asset to Exela Sterile
Medicines LLC (“Exela Buyer”) as part of the disposition of the Hospital Products.

Lease Obligations. The Company determines if a contract is a lease at the inception of the arrangement. Right-of-use assets and operating lease liabilities are recognized at commencement date based
on the present value of remaining lease payments over the lease term. For this purpose, the Company considers only payments that are fixed and determinable at the time of commencement. The
Company reviews all options to extend, terminate, or purchase its right-of-use assets at the inception of the lease and will include these options in the lease term when they are reasonably certain of
being exercised. Short term leases with an initial term of 12 months or less are not recorded on the balance sheet and the associated lease payments are recognized in the consolidated statements of
(loss) income on a straight-line basis over the lease term. The Company’s lease contracts do not provide a readily determinable implicit rate. The Company’s estimated incremental borrowing rate is
based on information available at the inception of the lease. The Company’s lease agreements may contain variable costs such as common area maintenance, insurance, real estate taxes or other costs.
Variable lease costs are expensed as incurred on the consolidated statements of (loss) income.

Use of Estimates. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of
assets and liabilities, including marketable securities and contingent liabilities at the date of the consolidated financial statements and the reported amounts of sales and expenses during the periods
presented. These estimates and assumptions are based on the best information available to management at the balance sheet dates and depending on the nature of the estimate can require significant
judgments. Changes to these estimates and judgments can have and have had a material impact on the Company’s consolidated statements of (loss) income and balance sheets. Actual results could
differ from those estimates under different assumptions or conditions.  

NOTE 2: Newly Issued Accounting Standards 

Recently Adopted Accounting Guidance

In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income
Taxes, as part of its overall simplification initiative to reduce costs and complexity of applying accounting standards while maintaining or improving the usefulness of the information provided to
users of financial statements. The FASB’s amendments primarily impact ASC 740, Income Taxes, and may impact both interim and annual reporting periods. ASU 2019-12 is effective for fiscal years
beginning after December 15, 2020, and interim periods within those fiscal years and early adoption is permitted. The Company adopted the provisions of ASU 2019-12 on January 1, 2021. Adoption
of ASU 2019-12 did not have any impact on the Company’s consolidated financial statements.

In August 2020, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging- Contracts in Entity’s Own Equity (Subtopic 815-40), to
reduce the complexity associated with applying U.S. GAAP principles for certain financial instruments with characteristics of liabilities and equity. The amendments in this ASU reduce the number
of accounting models for convertible instruments and expand the existing disclosure requirements over earnings per share as it relates to convertible instruments. Convertible debt will be accounted
for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The update also requires the if-converted method to be used for
convertible instruments and the effect of potential share settlement be included in the diluted earnings per share calculation when an instrument may be settled in cash or shares. This ASU will be
effective for the Company’s fiscal year beginning January 1, 2022 and interim periods therein. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The
amendments may be adopted through either a modified retrospective method, or a fully retrospective method.

-82-

The Company elected to early adopt ASU 2020-06 as of January 1, 2021 using a modified retrospective method. The Company’s 4.50% exchangeable senior notes due 2023 (the “2023 Notes”) are a
convertible instrument with a cash-conversion feature that is accounted for within the scope of Subtopic 470-20. The Company calculated the cumulative-effect adjustment as of January 1, 2021 by
comparing (i) the historical amortization schedule for the 2023 Notes through December 31, 2020 and (ii) an updated amortization schedule wherein the conversion feature within the 2023 Notes
would  not  be  separated  as  an  equity  component  and  subsequently  recognized  as  non-cash  interest  expense  under  ASC  835-30.  The  adoption  resulted  in  a  $26,699  decrease  in  additional  paid-in
capital, a $12,939 increase in long-term debt, and a $13,760 increase to the opening balance of retained earnings.

NOTE 3: Subsidiary Bankruptcy and Deconsolidation

On February 6, 2019, the Company deconsolidated Specialty Pharma effective with the filing of the Chapter 11 bankruptcy and recorded a non-cash charge of approximately $2,678 for the year
ended December 31, 2019.

The Company recognized a non-cash gain of $217 and $3,364 from the release of certain liabilities that had been retained following the deconsolidation of Specialty Pharma. These gains are included
in "Gain from release of certain liabilities" within non-operating (loss) income for the years ended December 31, 2021 and 2020.

On October 26, 2021, the U.S. Bankruptcy Court for the District of Delaware issued the Final Decree and Order, dismissing the bankruptcy case and dissolving Specialty Pharma.

NOTE 4: Disposition of the Hospital Products

On June 30, 2020 (the “Closing Date”), the Company announced the sale of its Hospital Products, which included its three FDA-approved commercial products, Akovaz, Bloxiverz and Vazculep, as
well as Nouress, to the Exela Buyer pursuant to an Asset Purchase Agreement (the “Transaction”).

Pursuant to the Transaction, the Exela Buyer agreed to pay a total aggregate consideration amount of $42,000, of which $14,500 was paid on the Closing Date and an additional $27,500 was paid in
ten equal monthly installments following the Closing Date. During the year ended December 31, 2020, the Company collected four installment payments, totaling $11,000. The Company collected
the remaining six installment payments, totaling $16,500 during 2021. In connection with the sale of the Hospital Products, the parties also agreed to cause the dismissal of the pending civil litigation
related to Nouress in the District Court for the District of Delaware.
The Company was party to a Membership Interest Purchase Agreement, dated March 13, 2012, by and among the Company, Avadel Legacy, Breaking Stick Holdings, LLC, Deerfield Private Design
International  II,  L.P.  (“Deerfield  International”),  Deerfield  Private  Design  Fund  II,  L.P.  (“Deerfield  Fund”)  and  Horizon  Santé  FLML,  Sarl  (“Horizon”)  (the  “Deerfield  MIPA”)  and  a  Royalty
Agreement, dated February 4, 2013, by and among the Company, Avadel Legacy, the Deerfield Fund and Horizon (the “Deerfield Royalty Agreement”). In connection with the closing of the sale of
the Hospital Products, the Deerfield MIPA (with respect to certain sections thereof) and the Royalty Agreement were assigned to the Exela Buyer. Pursuant to the Purchase Agreement, the Exela
Buyer assumed and will pay, perform, satisfy and discharge the liabilities and obligations of Avadel Legacy under the Deerfield Royalty Agreement for obligations that arise after the Closing Date.
The Company was also party to a Royalty Agreement, dated December 3, 2013, by and between the Company, Avadel Legacy and Broadfin Healthcare Master Fund, Ltd. (the “Broadfin Royalty
Agreement”). In connection with the closing of the sale of the Hospital Products, the Broadfin Royalty Agreement was assigned to the Exela Buyer and the Exela Buyer assumed and shall pay,
perform, satisfy and discharge the liabilities and obligations of Avadel Legacy under the Broadfin Royalty Agreement for obligations that arise after the Closing Date.

The Company recorded a net gain on the sale of the Hospital Products of $45,760 during the year ended December 31, 2020 which has been recorded on the consolidated statements of (loss) income.
The $45,760 gain represents the aggregate consideration of $42,000, less transaction fees of $2,928, plus the assets and liabilities either transferred to the Exela Buyer or eliminated by the Company
due to the sale of the Hospital Products, which are listed below.

Subsequent to the disposition of the Hospital Products, the Company entered into a separate and distinct agreement with the Exela Buyer, whereby the Exela Buyer assumed all future returns of the
Hospital  Products  in  exchange  for  cash  consideration  paid  by  the  Company.  The  Company  recorded  a  $518  gain  from  this  transaction,  which  is  recorded  in  “Selling,  general  and  administrative
expenses” for the year ended December 31, 2020.

The Company evaluated various qualitative and quantitative factors related to the disposition of the Hospital Products and determined that it did not meet the criteria for presentation as a discontinued
operation.

NOTE 5: Revenue Recognition

Prior to June 30, 2020, the Company generated revenue primarily from the sale of pharmaceutical products to customers. On June 30, 2020, the Company sold the Hospital Products. See Note 4:
Disposition of the Hospital Products.

Product Sales and Services

Prior  to  June  30,  2020,  the  Company  sold  products  primarily  through  wholesalers  and  considered  these  wholesalers  to  be  its  customers.  Revenue  from  product  sales  was  recognized  when  the
customer  obtained  control  of  the  Company’s  product  and  its  performance  obligations  were  met,  which  occurred  typically  upon  receipt  of  delivery  to  the  customer.  As  is  customary  in  the
pharmaceutical industry, the Company’s gross product sales were subject to a variety of price adjustments in arriving at reported net product sales. These adjustments included estimates for product
returns,  chargebacks,  payment  discounts,  rebates,  and  other  sales  allowances  and  are  estimated  when  the  product  is  delivered  based  on  analysis  of  historical  data  for  the  product  or  comparable
products, as well as future expectations for such products.

Reserves to reduce Gross Revenues to Net Revenues

Revenues from product sales were recorded at the net selling price, which included estimated reserves to reduce gross product sales to net product sales resulting from product returns, chargebacks,
payment discounts, rebates, and other sales allowances that are offered within contracts between the Company and its customers and end users. These reserves were based on the amounts earned or to
be claimed on the related sales and were classified as reductions of accounts receivable if the amount was payable to the customer, except in the case of the estimated reserve for future expired
product returns, which were classified as a liability. The reserves were classified as a liability if the amount is payable to a party other than a customer. Where appropriate, these estimated reserves
took  into  consideration  relevant  factors  such  as  the  Company’s  historical  experience,  current  contractual  and  statutory  requirements,  specific  known  market  events  and  trends,  industry  data  and
forecasted customer buying and payment patterns. Overall, these reserves reflected the Company’s best estimates to reduce gross selling price to net selling price to which it expected to be entitled
based on the terms of its contracts. The actual selling price ultimately received may differ from the Company’s estimates.

Product Returns

Consistent with industry practice, the Company maintained a returns policy that generally offered customers a right of return for product that has been purchased from the Company. The Company
estimated the amount of product returns and records this estimate as a reduction of revenue in the period the related product revenue was recognized. The Company estimated product return liabilities
based on analysis of historical data for the product or comparable products, as well as future expectations for such products and other judgments and analysis.

-85-

Chargebacks, Discounts and Rebates

Chargebacks, discounts and rebates represent the estimated obligations resulting from contractual commitments to sell products to its customers or end users at prices lower than the list prices charged
to  the  Company’s  wholesale  customers.  Customers  charged  the  Company  for  the  difference  between  the  gross  selling  price  they  pay  for  the  product  and  the  ultimate  contractual  price  agreed  to
between the Company and these end users. These reserves were established in the same period that the related revenue was recognized, resulting in a reduction of product revenue and accounts
receivable. Chargebacks, discounts and rebates were estimated at the time of sale to the customer.

Disaggregation of revenue

The Company’s primary source of revenue was from the sale of pharmaceutical products, which are equally affected by the same economic factors as it relates to the nature, amount, timing, and
uncertainty of revenue and cash flows. For further detail about the Company’s revenues by product, see Note 21: Company Operations by Product, Customer and Geography.

Contract Balances

The Company does not recognize revenue in advance of invoicing its customers and therefore has no related contract assets.

A receivable is recognized in the period the Company sells its products and when the Company’s right to consideration is unconditional.

There were no material deferred contract costs at December 31, 2021 and 2020.

Transaction Price Allocated to the Remaining Performance Obligation

For  product  sales,  the  Company  generally  satisfies  its  performance  obligations  within  the  same  period  the  product  is  delivered.  Product  sales  recognized  in  2020  and  2019  from  performance
obligations satisfied (or partially satisfied) in previous periods were immaterial. No product sales were recognized in 2021.

The  Company  has  elected  certain  of  the  practical  expedients  from  the  disclosure  requirement  for  remaining  performance  obligations  for  specific  situations  in  which  an  entity  need  not  estimate
variable  consideration  to  recognize  revenue.  Accordingly,  the  Company  applies  the  practical  expedient  in  ASC  606  to  its  stand-alone  contracts  and  does  not  disclose  information  about  variable
consideration from remaining performance obligations for which it recognizes revenue.

NOTE 6: Fair Value Measurements

The Company is required to measure certain assets and liabilities at fair value, either upon initial recognition or for subsequent accounting or reporting. For example, the Company uses fair value
extensively  when  accounting  for  and  reporting  certain  financial  instruments,  when  measuring  certain  contingent  consideration  liabilities  and  in  the  initial  recognition  of  net  assets  acquired  in  a
business combination. Fair value is estimated by applying the hierarchy described below, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within
the hierarchy upon the lowest level of input that is available and significant to the fair value measurement.

ASC 820, Fair Value Measurements and Disclosures, defines fair value as a market-based measurement that should be determined based on the assumptions that marketplace participants would use
in pricing an asset or liability. When estimating fair value, depending on the nature and complexity of the asset or liability, the Company may generally use one or each of the following techniques: 

•

Income approach, which is based on the present value of a future stream of net cash flows.

• Market approach, which is based on market prices and other information from market transactions involving identical or comparable assets or liabilities.

As a basis for considering the assumptions used in these techniques, the standard establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:  

•

Level 1 - Quoted prices for identical assets or liabilities in active markets.

-86-

•

•

Level 2 - Quoted prices for similar assets or liabilities in active markets, or quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted
prices that are directly or indirectly observable, or inputs that are derived principally from, or corroborated by, observable market data by correlation or other means.

Level 3 - Unobservable inputs that reflect estimates and assumptions.

The following table summarizes the financial instruments measured at fair value on a recurring basis classified in the fair value hierarchy (Level 1, 2 or 3) based on the inputs used for valuation in the
accompanying consolidated balance sheets:

A  review  of  fair  value  hierarchy  classifications  is  conducted  on  a  quarterly  basis.    Changes  in  the  observability  of  valuation  inputs  may  result  in  a  reclassification  for  certain  financial  assets  or
liabilities. During the fiscal year ended December 31, 2021, there were no transfers in and out of Level 1, 2, or 3. During the twelve months ended December 31, 2021, 2020 and 2019, the Company
did not recognize any allowances for credit losses.

Some of the Company’s financial instruments, such as cash and cash equivalents and accounts payable, are reflected in the balance sheet at carrying value, which approximates fair value due to their
short-term nature.

Debt

The Company estimates the fair value of its $143,750 aggregate principal amount of the 2023 Notes based on interest rates that would be currently available to the Company for issuance of similar
types of debt instruments with similar terms and remaining maturities or recent trading prices obtained from brokers (a Level 2 input). The estimated fair value of the 2023 Notes at December 31,
2021 is $153,273. See Note 11: Long-Term Debt for additional information regarding the Company’s debt obligations.

NOTE 7: Marketable Securities 

The Company has investments in available-for-sale debt securities that are recorded at fair market value. The change in the fair value of available-for-sale debt investments is recorded as accumulated
other comprehensive loss in shareholders’ equity, net of income tax effects. As of December 31, 2021, the Company considered any decreases in fair value on its marketable securities to be driven by
factors other than credit risk, including market risk.

The  following  tables  show  the  Company’s  available-for-sale  securities’  adjusted  cost,  gross  unrealized  gains,  gross  unrealized  losses  and  fair  value  by  significant  investment  category  as

The Company determines realized gains or losses on the sale of marketable securities on a specific identification method. The Company reflects these gains and losses as a component of investment
and other income in the accompanying consolidated statements of (loss) income.

The Company recognized gross realized gains of $174, $474 and $483 for the twelve months ended December 31, 2021, 2020 and 2019, respectively. These realized gains were offset by realized
losses of $275, $912 and $151 for the twelve-months ended December 31, 2021, 2020 and 2019, respectively.

The following table summarizes the estimated fair value of the Company’s investments in marketable debt securities, accounted for as available-for-sale securities and classified by the contractual

The Company has classified its investment in available-for-sale marketable securities as current assets in the consolidated balance sheets as the securities need to be available for use, if required, to
fund current operations. There are no restrictions on the sale of any securities in the Company’s investment portfolio.

Total  gross  unrealized  losses  of  the  Company’s  available-for-sale  debt  securities  at  December  31,  2021  were  immaterial  and  have  been  in  an  unrealized  loss  position  for  less  than  one  year.  The
unrealized losses are driven by factors other than credit risk. The Company does not intend to sell the investments and it is not more likely than not that it will be required to sell the investments
before recovery of their amortized cost bases.

NOTE 8: Property and Equipment, net

The principal categories of property and equipment, net at December 31, 2021 and 2020, respectively, are as follows:

NOTE 9: Goodwill and Intangible Assets 

The Company’s goodwill is $16,836 at December 31, 2021 and 2020.

The Company recorded amortization expense related to an amortizable intangible asset that was assumed by the Exela Buyer as part of the disposition of the Hospital Products on June 30, 2020 of
$406 and $816 for the years ended December 31, 2020 and 2019, respectively. Refer to Note 4: Disposition of the Hospital Products. There was no amortization expense recorded during the year
ended December 31, 2021.

No impairment loss related to goodwill or intangible assets was recognized during the years ended December 31, 2021 or 2020.

NOTE 10: Leases

The Company leases office space and a production suite. All leased facilities are classified as operating leases with remaining lease terms between two and four years. The Company determines if a
contract is a lease at the inception of the arrangement. The Company reviews all options to extend, terminate, or purchase its right-of-use assets at the inception of the lease and will include these
options  in  the  lease  term  when  they  are  reasonably  certain  of  being  exercised.  The  Company’s  lease  agreements  do  not  contain  any  material  residual  value  guarantees  or  material  variable  lease
payments. For the Company’s leased production suite, contract consideration was allocated to lease and non-lease components on the basis of relative standalone price.

The components of lease costs, which are included in selling, general and administrative expenses in the consolidated statements of (loss) income of years ended December 31, 2021, 2020 and 2019

remeasured its production suite lease liability. During the year ended December 31, 2021, the Company did not enter into any new operating or finance leases.

As of December 31, 2021, the Company’s operating leases have a weighted-average remaining lease term of 2.9 years and a weighted-average discount rate of 4.9%. The Company’s lease contracts
do not provide a readily determinable implicit rate. The Company’s estimated incremental borrowing rate is based on information available at the inception of the lease.

For the years ended December 31, 2021, 2020 and 2019, the total interest expense was $9,942, $12,994 and $12,464, respectively, with coupon interest expense of $6,469 for each period and the
amortization of debt issuance costs and debt discount of $1,248, $6,525 and $5,995, respectively. Current period interest expense also included $2,225 of additional interest expense owed as a result
of not removing a restrictive legend from the 2023 Notes 365 days following original issuance of the 2023 Notes on February 16, 2018. See Note 1: Background and Basis of Presentation for further
details.

As described in Note 2: Newly Issued Accounting Standards, the Company elected to early adopt ASU 2020-06 as of January 1, 2021 using a modified retrospective method. The adoption resulted in
a $12,939 increase in long-term debt and a $26,699 decrease in the equity component of the 2023 Notes.

2023 Notes

On February 16, 2018, Avadel Finance Cayman Limited, a Cayman Islands exempted company and an indirect wholly-owned subsidiary of the Company (the “Issuer”), issued $125,000 aggregate
principal amount of 4.50% exchangeable senior notes due 2023 (the “2023 Notes”) in a private placement (the “Offering”) to qualified institutional buyers pursuant to Rule 144A under the Securities
Act. In connection with the Offering, the Issuer granted the initial purchasers of the 2023 Notes a 30-day option to purchase up to an additional $18,750 aggregate principal amount of the 2023 Notes,
which was fully exercised on February 16, 2018. Net proceeds received by the Company, after issuance costs and discounts, were approximately $137,560. The 2023 Notes are the Company’s senior
unsecured obligations and rank equally in right of payment with all of the Company’s existing and future senior unsecured indebtedness and effectively junior to any of the Company’s existing and
future secured indebtedness, to the extent of the value of the assets securing such indebtedness.

The 2023 Notes will be exchangeable at the option of the holders at an initial exchange rate of 92.6956 ADSs per $1 principal amount of 2023 Notes, which is equivalent to an initial exchange price
of approximately $10.79 per ADS. Such initial exchange price represents a premium of approximately 20% to the $8.99 per ADS closing price on The Nasdaq Global Market on February 13, 2018.
Upon the exchange of any 2023 Notes, the Issuer will pay or cause to be delivered, as the case may be, cash, ADSs or a combination of cash and ADSs, at the Issuer’s election. Holders of the 2023
Notes may convert their 2023 Notes, at their option, only under the following circumstances prior to the close of business on the business day immediately preceding August 1, 2022, under the
circumstances and during the periods set forth below and regardless of the conditions described below, on or after August 1, 2022 and prior to the close of business on the business day immediately
preceding the maturity date:

•

•

Prior to the close of business on the business day immediately preceding August 1, 2022, a holder of the 2023 Notes may surrender all or any portion of its 2023 Notes for exchange at any
time during the five business day period immediately after any five consecutive trading day period (the “Measurement Period”) in which the trading price per $1 principal amount of 2023
Notes, as determined following a request by a holder of the 2023 Notes, for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the
ADSs and the exchange rate on each such trading day.

If a transaction or event that constitutes a fundamental change or a make-whole fundamental change occurs prior to the close of business on the business day immediately preceding August
1, 2022, regardless of whether a holder of the 2023 Notes has the right to require the Company to repurchase the 2023 Notes, or if Avadel is a party to a merger

-90-

event that occurs prior to the close of business on the business day immediately preceding August 1, 2022, all or any portion of a the holder’s 2023 Notes may be surrendered for exchange at
any time from or after the date that is 95 scheduled trading days prior to the anticipated effective date of the transaction (or, if later, the earlier of (x) the business day after the Company gives
notice of such transaction and (y) the actual effective date of such transaction) until 35 trading days after the actual effective date of such transaction or, if such transaction also constitutes a
fundamental change, until the related fundamental change repurchase date.

•

•

Prior to the close of business on the business day immediately preceding August 1, 2022, a holder of the 2023 Notes may surrender all or any portion of its 2023 Notes for exchange at any
time during any calendar quarter commencing after the calendar quarter ending on June 30, 2018 (and only during such calendar quarter), if the last reported sale price of the ADSs for at
least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar
quarter is greater than or equal to 130% of the exchange price on each applicable trading day.

If the Company calls the 2023 Notes for redemption pursuant to Article 16 to the Indenture prior to the close of business on the business day immediately preceding August 1, 2022, then a
holder of the 2023 Notes may surrender all or any portion of its 2023 Notes for exchange at any time prior to the close of business on the second business day prior to the redemption date,
even if the 2023 Notes are not otherwise exchangeable at such time. After that time, the right to exchange shall expire, unless the Company defaults in the payment of the redemption price,
in which case a holder of the 2023 Notes may exchange its 2023 Notes until the redemption price has been paid or duly provided for.

The Company considered the guidance in ASC 815-15, Embedded Derivatives, to determine if this instrument contains an embedded feature that should be separately accounted for as a derivative.
ASC 815 provides for an exception to this rule when convertible notes, as host instruments, are deemed to be conventional, as defined by ASC 815-40. The Company determined that this exception
applies due, in part, to its ability to settle the 2023 Notes in cash, ADSs or a combination of cash and ADSs, at the Company’s option. The Company have therefore applied the guidance provided by
ASC 470-20, Debt with Conversion and Other Options, as amended by ASU 2020-06.

NOTE 12: Contingent Consideration Payable 

Prior to the sale of the Hospital Products on June 30, 2020, the Company computed the fair value of the contingent consideration using several significant assumptions and when those assumptions
changed, due to underlying market conditions, the fair value of these liabilities changed as well. Prior to the sale of the Hospital Products, these changes had a material impact on the Company’s
consolidated statements of (loss) income and balance sheets. As part of the sale of the Hospital Products on June 30, 2020, the Exela Buyer assumed and will pay, perform, satisfy and discharge the
liabilities and obligations of Avadel Legacy and the Company under the Deerfield Royalty Agreement and the Broadfin Royalty Agreement. As of December 31, 2021 and 2020, the balance of the
contingent consideration payable is $0.

The following table summarizes changes to the contingent consideration payables, a recurring Level 3 measurement, for the twelve-month periods ended December 31, 2020 and 2019:

In 2021, the income tax benefit increased by $3,706 when compared to the same period in 2020. The increase in the income tax benefit in 2021 was primarily driven by the additional tax benefit from
an increase in the net operating losses in the U.S. in 2021, when compared to the same period in 2020. This was partially offset by the nonrecurring nature of tax benefits recognized in 2020 from the
sale of the Company’s Hospital Products and passage of the Coronavirus Aid, Relief and Economic Security Act (the “CARES Act”) in the U.S.

-92-

 
 
 
 
 
 
In 2020, the income tax benefit increased by $6,754 when compared to the same period in 2019. The increase in the income tax benefit in 2020 was primarily driven by the tax benefits from the sale
of the Company’s Hospital Products and passage of the CARES Act in the U.S. The Company recorded additional tax benefit in 2020 from the Orphan Drug and R&D tax credit in the U.S. Tax
benefit from the intercompany asset transfer recorded in 2019 did not recur, resulting in a partial offset of tax benefits described above.

Unrecognized Tax Benefits

The  Company  or  one  of  its  subsidiaries  files  income  tax  returns  in  Ireland,  France,  U.S.  and  various  states.  The  Company  is  no  longer  subject  to  Irish,  French,  U.S.  Federal,  and  state  and  local
examinations for years before 2017. During 2020, the Company completed the 2015 through 2017 U.S. Federal Tax Audit. Completion of the audit resulted in an assessment of $1,937 for the 2015
through 2017 U.S. Federal Tax Returns compared to the IRS Claims of $50,695 made on July 2, 2019 and the updated IRS Claims of $9,302 on October 2, 2019 made as part of the Specialty Pharma
bankruptcy proceedings, which at this time does not include interest and penalties.

The following table summarizes the activity related to the Company’s unrecognized tax benefits for the twelve months ended
December 31:

The Company expects that within the next twelve months the unrecognized tax benefits could decrease by an immaterial amount and the interest could increase by an immaterial amount.

At December 31, 2021, 2020 and 2019, there are $2,483, $2,483 and $3,806 of unrecognized tax benefits that if recognized would affect the annual effective tax rate.

The  Company  recognizes  interest  and  penalties  accrued  related  to  unrecognized  tax  benefits  in  income  tax  expense.  During  the  years  ended  December  31,  2021,  2020  and  2019,  the  Company
recognized approximately $239, $203 and $555 in interest and penalties. The Company had approximately $1,777 and $1,475 for the payment of interest and penalties accrued at December 31, 2021
and 2020, respectively.

Deferred Tax Assets (Liabilities) 

Deferred  income  tax  provisions  reflect  the  effect  of  temporary  differences  between  consolidated  financial  statement  and  tax  reporting  of  income  and  expense  items.  The  net  deferred  tax  assets
(liabilities) at December 31, 2021 and 2020 resulted from the following temporary differences:

At  December  31,  2021,  the  Company  had  $124,720  of  net  operating  losses  in  Ireland  that  do  not  have  an  expiration  date  and  $74,406  of  net  operating  losses  in  the  U.S.  Of  the  $74,406  of  net
operating losses in the U.S., $10,365 were acquired due to the acquisition of FSC Therapeutics and FSC Laboratories, Inc., (collectively “FSC”) and $64,041 are due to the losses at US Holdings. The
portion due to the acquisition of FSC will expire in 2034 through 2035. A valuation allowance is recorded if, based on the weight of available evidence, it is more likely than not that a deferred tax
asset will not be realized. This assessment is based on an evaluation of the level of historical taxable income and projections for future taxable income. For the year ended December 31, 2021, the
Company  recorded  $4,045  of  valuation  allowances  related  to  Irish  net  operating  losses.  The  U.S.  net  operating  losses  are  subject  to  an  annual  limitation  as  a  result  of  the  FSC  acquisition  under
Internal Revenue Code Section 382 and will not be fully utilized before they expire.

The Company recorded a valuation allowance against all of its net operating losses in Ireland and France as of December 31, 2021 and 2020. The Company intends to continue maintaining a full
valuation allowance on the Irish net operating losses until there is sufficient evidence to support the reversal of all or some portion of these allowances.

While  the  Company  believes  it  is  more  likely  than  not  that  it  will  be  able  to  realize  the  deferred  tax  assets  in  the  U.S.,  the  Company  continues  to  monitor  any  unfavorable  changes  that  could
ultimately impact its assessment of the realizability of the Company’s U.S. deferred tax assets. If the Company experiences an ownership change under Internal Revenue Code Section 382, the U.S.
net operating losses could also be limited in their utilization.

At  December  31,  2021,  the  Company  has  unremitted  earnings  of  $3,916  outside  of  Ireland  as  measured  on  a  U.S.  GAAP  basis.  Whereas  the  measure  of  earnings  for  purposes  of  taxation  of  a
distribution  may  be  different  for  tax  purposes,  these  earnings,  which  are  considered  to  be  invested  indefinitely,  would  become  subject  to  income  tax  if  they  were  remitted  as  dividends  or  if  the
Company were to sell its stock in the subsidiaries, net of any prior income taxes paid. It is not practicable to estimate the amount of deferred tax liability on such earnings, if any.

R&D Tax Credits Receivable 

The French and Irish governments provide tax credits to companies for spending on innovative R&D. These credits are recorded as an offset of R&D expenses and are credited against income taxes
payable in years after being incurred or, if not so utilized, are recoverable in cash after a specified period of time, which may differ depending on the tax credit regime. As of December 31, 2021, the
Company’s net research tax credit receivable amounts to $3,668 and represents a French gross research

-94-

 
 
 
 
tax credit of $3,139 and an Irish gross research tax credit of $529. As of December 31, 2020, the Company’s net research tax credit receivable amounts to $6,771 and represents a French gross
research tax credit of $6,396 and an Irish gross research tax credit of $375.

2020 CARES Act

The CARES Act, enacted on March 27, 2020, includes significant business tax provisions. In particular, the CARES Act modified the rules associated with net operating losses. Under the temporary
provisions of the CARES Act, net operating loss carryforwards and carrybacks may offset 100% of taxable income for taxable years beginning before 2021. In addition, net operating losses arising in
2018, 2019 and 2020 taxable years may be carried back to each of the preceding five years to generate a refund. During the twelve months ended December 31, 2020, the income tax benefit includes
a discrete tax benefit of $9,124 as a result of the Company’s ability under the CARES Act to carry back net operating losses incurred to periods when the statutory U.S. Federal tax rate was 35%
versus the Company’s current U.S. Federal tax rate of 21%. During the twelve months ended December 31, 2020, the Company received $3,351 in cash tax refunds from carryback claims related to
the CARES Act from the carryback of 2018 tax losses. The Company filed refund claims for $18,753 associated with the carryback of 2019 tax losses and a $10,273 refund claim associated with the
carryback of 2020 tax losses.

The  Company  is  subject  to  potential  liabilities  generally  incidental  to  its  business  arising  out  of  present  and  future  lawsuits  and  claims  related  to  product  liability,  personal  injury,  contract,
commercial, intellectual property, tax, employment, compliance and other matters that arise in the ordinary course of business. The Company accrues for potential liabilities when it is probable that
future costs (including legal fees and expenses) will be incurred and such costs can be reasonably estimated. At December 31, 2021, there were no contingent liabilities with respect to any litigation,
arbitration or administrative or other proceeding that are reasonably likely to have a material adverse effect on the Company’s consolidated financial position, results of operations, cash flows or
liquidity.  

First Complaint

On May 12, 2021, Jazz Pharmaceuticals, Inc. (“Jazz”) filed a formal complaint (the “First Complaint”) initiating a lawsuit in the United States District Court for the District of Delaware (the “Court”)
against Avadel Pharmaceuticals plc, Avadel US Holdings, Inc., Avadel Management Corporation, Avadel Legacy Pharmaceuticals, LLC, Avadel Specialty Pharmaceuticals, LLC, and Avadel CNS
Pharmaceuticals,  LLC  (collectively,  the  “Avadel  Parties”).  In  the  First  Complaint,  Jazz  alleges  the  sodium  oxybate  product  (“Proposed  Product”)  described  in  the  NDA  owned  by  Avadel  CNS
Pharmaceuticals, LLC will infringe at least one claim of US Patent No. 8731963, 10758488, 10813885, 10959956 and/or 10966931 (collectively, the “patents-in-suit”). The First Complaint further
includes typical relief requests such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses.

On June 3, 2021, the Avadel Parties timely filed their Answer and Counterclaims (the “Avadel Answer”) with the Court in response to the First Complaint. The Avadel Answer generally denies the
allegations set forth in the First Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patents-in-suit), and asserts a number of
counterclaims seeking i) a declaratory judgment of non-infringement of each patent-in-suit, and ii) a declaratory judgment of invalidity of each patent-in-suit.

On June 18, 2021, Jazz filed its Answer (“Jazz Answer”) with the Court in response to the Avadel Answer. The Jazz Answer generally denies the allegations set forth in the Avadel Answer and sets
forth a single affirmative defense asserting that Avadel has failed to state a claim for which relief can be granted.

On June 21, 2021, the Court issued an oral order requiring the parties to i) confer regarding proposed dates to be included in the Court’s scheduling order for the case, and ii) submit a proposed order,
including a proposal for the length and timing of trial, to the Court by no later than July 21, 2021.

On July 30, 2021, the Court issued a scheduling order establishing timing for litigation events including i) a claim construction hearing date of August 2, 2022, and ii) a trial date of October 30, 2023.

On October 18, 2021, consistent with the scheduling order, Jazz filed a status update with the Court indicating that Jazz did not intend to file a preliminary injunction with the Court at this time. Jazz
further indicated that it would provide the Court with an

-96-

 
update regarding whether preliminary injunction proceedings may be necessary after receiving further information regarding the FDA’s action on Avadel’s NDA.

On January 4, 2022, the Court entered an agreed order dismissing this case with respect to Avadel Pharmaceuticals plc, Avadel US Holdings, Inc., Avadel Specialty Pharmaceuticals, LLC, Avadel
Legacy Pharmaceuticals, LLC, and Avadel Management Corporation. A corresponding order was entered in the two below cases on the same day.

Second Complaint

On August 4, 2021, Jazz filed another formal complaint (the “Second Complaint”) initiating a lawsuit in the Court against the Avadel Parties. In the Second Complaint, Jazz alleges the Proposed
Product described in the NDA owned by Avadel CNS Pharmaceuticals, LLC will infringe at least one claim of US Patent No. 11077079. The Second Complaint further includes typical relief requests
such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses.

Answer generally denies the allegations set forth in the Second Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patent-in-
suit), and asserts a number of counterclaims seeking i) a declaratory judgment of non-infringement of the patent-in-suit, and ii) a declaratory judgment of invalidity of the patent-in-suit.

On October 22, 2021, the Court issued an oral order stating that this case should proceed on the same schedule as the case filed on May 12, 2021.

Third Complaint

On November 10, 2021, Jazz filed another formal complaint (the “Third Complaint”) initiating a lawsuit in the Court against the Avadel Parties. In the Third Complaint, Jazz alleges the Proposed
Product described in the NDA owned by Avadel CNS Pharmaceuticals, LLC will infringe at least one claim of US Patent No. 11147782. The Third Complaint further includes typical relief requests
such as preliminary and permanent injunctive relief, monetary damages and attorneys’ fees, costs and expenses. This case will proceed on the same schedule as the cases associated with the First and
Second Complaints above.

On January 7, 2022, Avadel CNS Pharmaceuticals LLC timely filed its Answer and Counterclaims (the “Third Avadel Answer”) with the Court in response to the Third Complaint. The Third Avadel
Answer generally denies the allegations set forth in the Third Complaint, includes numerous affirmative defenses (including, but not limited to, non-infringement and invalidity of the patent-in-suit),
and asserts a number of counterclaims seeking i) a declaratory judgment of non-infringement of the patent-in-suit, and ii) a declaratory judgment of invalidity/unenforceability of the patent-in-suit.

On December 21, 2021, the Court entered a revised schedule for the First, Second and Third Complaints, setting a new claim construction date of August 31, 2022.

Material Commitments  

At  December  31,  2021,  the  Company  has  one  commitment  with  its  primary  contract  manufacturer  related  to  facility  upgrades  and  the  purchase  and  validation  of  equipment  to  be  used  in  the
manufacture of FT218. The total cost of this commitment is estimated to be approximately $5,500 and is expected to be completed during the year ending December 31, 2022. The Company has
incurred approximately $3,348 of this commitment during the year ended December 31, 2021.

The  Company  also  has  a  commitment  with  another  contract  manufacturer  that  commences  in  the  first  quarter  of  2022  and  will  continue  until  FDA  approval  of  the  contract  manufacturer.  The

Guarantees

Deerfield Guarantee

In  connection  with  the  Company’s  February  2018  divestiture  of  its  pediatric  assets,  including  four  pediatric  commercial  stage  assets  –  Karbinal™  ER,  Cefaclor,  Flexichamber™  and  AcipHex®
Sprinkle™ (“FSC products”), to Cerecor, Inc. (“Cerecor”), the Company guaranteed to Deerfield a quarterly royalty payment of 15% on net sales of the FSC products through February 6, 2026
(“FSC Product Royalties”), in an aggregate amount of up to approximately $10,300. Given the Company’s explicit

-97-

 
guarantee to Deerfield, the Company recorded the guarantee in accordance with ASC 460. The balance of this guarantee liability was $1,054 at December 31, 2021. This liability is being amortized
proportionately based on undiscounted cash outflows through the remainder of the contract with Deerfield.

Armistice Guarantee

In connection with the Company’s February 2018 divestiture of the pediatric assets, Armistice Capital Master Fund, Ltd., the majority shareholder of Cerecor, guaranteed to the Company the FSC
Product  Royalties.  The  Company  recorded  the  guarantee  in  accordance  with  ASC  460.  The  balance  of  this  guarantee  asset  was  $1,050  at  December  31,  2021.  This  asset  is  being  amortized
proportionately based on undiscounted cash outflows through the remainder of the contract with Deerfield.

The fair values of the Company’s guarantee to Deerfield and the guarantee received by the Company from Armistice largely offset and when combined are not material.

NOTE 16: Restructuring Costs 

2019 French Restructuring

During the second quarter of 2019, the Company initiated a plan to discontinue all French R&D activities, which resulted in the redundancy and reduction of its entire workforce at its Vénissieux,
France  site  (“2019  French  Restructuring”).  This  reduction  was  part  of  an  effort  to  align  the  Company’s  cost  structure  with  its  ongoing  and  future  planned  projects.  The  discontinuation  of  R&D
activities and elimination of the workforce in France was completed during the year ended December 31, 2020. Restructuring charges associated with this plan recognized during the years ended
December 31, 2021 and 2020 were immaterial. Restructuring charges associated with this plan of $4,855 of were recognized during the year ended December 31, 2019. Included in the 2019 French
Restructuring charges of $4,855 were charges for employee severance, benefits and other costs of $4,339, charges related to fixed asset impairment of $629, charges related to the early termination
penalty related to the office and copier lease terminations of $887, partially offset by a benefit of $1,000 related to the reversal of the French retirement indemnity obligation. At December 31, 2021,
there are no future expected retirement indemnity benefits to be paid. The Company does not expect to incur any additional expenses related to the 2019 French Restructuring. The following table
sets forth activities for the Company’s cost reduction plan obligations for the years ended December 31, 2021 and 2020:

The 2019 French Restructuring liability of $41 is included in the consolidated balance sheet in accrued expenses at December 31, 2021.

2019 Corporate Restructuring

During the first quarter of 2019, the Company announced a plan to reduce its corporate workforce by more than 50% (the “2019 Corporate Restructuring”). The reduction in workforce is primarily a
result of the exit of Noctiva during the first quarter of 2019 (see Note 3: Subsidiary Bankruptcy and Deconsolidation), as well as an effort to better align the Company’s remaining cost structure at its
U.S. and Ireland locations with its ongoing and future planned projects. The reduction in workforce was completed during the year ended December 31, 2020. Restructuring income associated with
this plan for the years ended December 31, 2021 and 2020 were immaterial. Restructuring charges associated with this plan of $1,755 were recognized during the year ended December 31, 2019.
Included in the 2019 Corporate Restructuring charges of $1,755 for the year ended December 31, 2019 were charges for employee severance, benefit and other costs of $3,406, charges related to the
early termination penalty related to the office lease termination of $288, the write-off of $125 of property, plant and equipment, net, partially offset by a benefit of $2,064 related to share based
compensation  forfeitures  related  to  the  employees  affected  by  the  global  reduction  in  workforce.  The  Company  does  not  expect  to  incur  any  additional  expenses  related  to  the  2019  Corporate
Restructuring.

-98-

During the years ended December 31, 2021, 2020 and 2019, the Company paid $272, $1,014, and $2,326 respectively, and has no remaining obligation for the 2019 Corporate Restructuring plan as of
December 31, 2021.

NOTE 17: Equity Instruments and Transactions

The transactions costs associated with the 2020 Shelf Registration Statement totaled $428 of which $214 was charged against additional paid-in capital during the twelve months ended December 31,
2020 as a result of the May 2020 Public Offering, discussed below. The remaining costs of $214 are recorded as a prepaid asset at December 31, 2021.

February 2020 Private Placement

On February 21, 2020, the Company announced that it entered into a definitive agreement for the sale of its ADSs and Series A Non-Voting Convertible Preferred Shares (“Series A Preferred”) in a
private placement to a group of institutional accredited investors. The private placement resulted in gross proceeds of approximately $65,000 before deducting placement agent and other offering
expenses, which resulted in net proceeds of $60,570.

Pursuant to the terms of the private placement, the Company issued 8,680 ADSs and 488 shares of Series A Preferred at a price of $7.09 per share, priced at-the-market under Nasdaq rules. Each
share of non-voting Series A Preferred is convertible into one ADS, provided that conversion will be prohibited if, as a result, the holder and its affiliates would own more than 9.99% of the total
number of Avadel ADSs outstanding. The closing of the private placement occurred on February 25, 2020.

Issuance costs of $4,430 have been recorded as a reduction of additional paid-in capital.

May 2020 Public Offering

In connection with the shelf registration statement described above, on April 28, 2020, the Company announced the pricing of an underwritten public offering of 11,630 Ordinary Shares, in the form
of ADSs at a price to the public of $10.75 per ADS. Each ADS represents the right to receive one Ordinary Share. All of the ADSs were offered by the Company and the gross proceeds to the
Company from the offering were approximately $125,000, before deducting underwriting discounts and commissions and offering expenses, which resulted in net proceeds of $116,924. The offering
closed on May 1, 2020.

Retirement of Treasury Shares

In August 2020, the Company retired all of its 5,407 treasury shares, or $49,998 previously repurchased ordinary shares. As a result, the Company reduced additional paid-in capital by $49,944 and
ordinary shares by $54 during the twelve months ended December 31, 2020. The portion allocated to additional paid-in capital is determined pro rata by applying a percentage, determined by dividing
the  number  of  shares  to  be  retired  by  the  number  of  shares  issued  and  outstanding  as  of  the  retirement  date,  to  the  balance  of  additional  paid-in  capital  as  of  the  retirement  date.  Based  on  this
calculation, the entirety of the excess of repurchase price over par of $49,944 was allocated to additional paid-in capital.

NOTE 18: Share-Based Compensation 

Compensation expense included in the Company’s consolidated statements of (loss) income for all share-based compensation arrangements was as follows for the periods ended December 31, 2021,
2020 and 2019, respectively:

As of December 31, 2021, the Company expects $18,429 of unrecognized expense related to granted, but non-vested share-based compensation arrangements to be incurred in future periods. This
expense is expected to be recognized over a weighted average period of 3.2 years. 

The excess tax benefit related to share-based compensation recorded by the Company was not material for the years ended December 31, 2021, 2020 and 2019.

Upon exercise of stock options, or upon the issuance of restricted share awards or performance share unit awards, the Company issues new shares. 

At December 31, 2021, there were 1,336 shares authorized for stock option grants, restricted share award grants, and performance share unit award grants in subsequent periods. 

Inducement Plan

In November 2021, the Board of Directors approved the Avadel Pharmaceuticals plc 2021 Inducement Plan (the “Inducement Plan”), which allows the Company to grant equity awards to induce
highly-qualified  prospective  officers  and  employees  who  are  not  currently  employed  by  the  Company  to  accept  employment  and  provide  them  with  a  proprietary  interest  in  the  Company.  The
maximum number of shares reserved and available for issuance under the Plan is 1,500 shares. As of December 31, 2021, the Company had not issued any shares under this Inducement Plan.

Determining the Fair Value of Stock Options

The Company measures the total fair value of stock options on the grant date using the Black-Scholes option-pricing model and recognizes each grant’s fair value as compensation expense over the
period that the option vests. Options are granted to employees of the Company and become exercisable ratably over four years following the grant date and expire ten years after the grant date. Prior
to 2021, the Company issued stock options to its Board of Directors as compensation for services rendered that are exercisable ratably over three years following the grant date, and expire ten years
after the grant date. In 2021, the Company issued stock options to its Board of Directors as compensation for services rendered and are exercisable one year following the grant date and expire ten
years after the grant date.

The weighted-average assumptions under the Black-Scholes option-pricing model for stock option grants as of December 31, 2021, 2020 and 2019, are as follows:

Expected term:  The  expected  term  of  the  options  represents  the  period  of  time  between  the  grant  date  and  the  time  the  options  are  either  exercised  or  forfeited,  including  an  estimate  of  future
forfeitures for outstanding options. Given the limited historical data, the simplified method has been used to calculate the expected life. 

Expected volatility: The expected volatility is calculated based on an average of the historical volatility of the Company’s stock price for a period approximating the expected term. 

Risk-free interest rate: The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant and a maturity that approximates the expected term. 

Expected dividend yield: The Company has not distributed any dividends since its inception and have no plan to distribute dividends in the foreseeable future.

The weighted average grant date fair value of options granted during the years ended December 31, 2021, 2020 and 2019 was $5.36, $4.63 and $1.24 per share, respectively. 

Restricted Share Awards 

Restricted share awards represent Company shares issued free of charge to employees of the Company as compensation for services rendered. The Company measures the total fair value of restricted
share awards on the grant date using the Company’s stock price at the time of the grant. Restricted share awards granted from 2017-2020 vest over a three-year period; two-thirds (2/3) vesting on the
second anniversary of the grant date and the remaining one-third (1/3) vesting on the third anniversary of the grant date.  In 2021, restricted share awards granted to employees vest over a four-year
period; one-fourth (1/4) on each anniversary of the grant date. In 2018, the Company issued restricted share awards to its Board of Directors vesting over a three-year period; one-third (1/3) vesting
on each of the three anniversaries of the grant date. Compensation expense for such awards granted during and after 2017 is recognized over the applicable vesting period. 

A summary of the Company’s restricted share awards as of December 31, 2021, and changes during the year then ended, is reflected in the table below.

Performance Share Units Awards

Performance share units awards (“PSUs”) represent Company shares issued free of charge to employees of the Company as compensation for achieving various results. The Company measures the
total fair value of performance share unit awards on the grant date using the Company’s stock price at the time of the grant. In 2020, the Company granted performance share awards, of which 50%
vest upon the achievement of certain regulatory milestones related to FT218 and the other 50% vest one year following achievement of those milestones (“2020 PSU awards”). The Company has not
yet recognized any share-based compensation expense related to the 2020 PSU awards as the regulatory milestones have not yet been met; however, in the event the performance conditions are met
before a certain date, approximately 100% of the outstanding shares, or $1,786 of compensation expense will be recognized by the Company for the 2020 PSU awards outstanding as of December 31,
2021.

In 2021, the Company granted performance share awards of which 50% vest upon achievement of certain corporate objectives and the second 50% vests one year following achievement of those
objectives (“2021 PSU awards”). The Company has not yet recognized any share-based compensation expense related to the 2021 PSU awards as the objectives have not yet been met; however, in
the event the performance conditions are met and exceeded, approximately 150% of the outstanding shares, or $3,509 of compensation expense will be recognized by the Company for the 2021 PSU
awards outstanding as of December 31, 2021.

Employee Share Purchase Plan

In 2017, the Board of Directors approved the Avadel Pharmaceuticals plc 2017 Avadel Employee Share Purchase Plan (“ESPP”). The total number of Company ordinary shares, nominal value $0.01
per share, or ADSs representing such ordinary shares (collectively, “Shares”) which may be issued under the ESPP is 1,000. The purchase price at which a share will be issued or sold for a given
offering period will be established by the Compensation Committee of the Board (“Committee”) (and may differ among participants, as determined by the Committee in its sole discretion) but will in
no event be less than 85% of the lesser of: (a) the fair market value of a Share on the offering date; or (b) the fair market value of a Share on the purchase date. During the years ended December 31,
2021 and 2020, the Company issued 17 and 49 ordinary shares to employees, respectively. Expense related to the ESPP for the years ended December 31, 2021, 2020 and 2019 was immaterial.

NOTE 19: Net (Loss) Income Per Share 

Basic  net  (loss)  income  per  share  is  calculated  by  dividing  net  (loss)  income  by  the  weighted  average  number  of  shares  outstanding  during  each  period.  Diluted  net  (loss)  income  per  share  is
calculated by dividing net (loss) income - diluted by the diluted number of shares outstanding during each period. Except where the result would be anti-dilutive to net (loss) income, diluted net (loss)
income per share would be calculated assuming the impact of the conversion of the 2023 Notes, the conversion of the Company’s preferred shares, the exercise of outstanding equity compensation
awards, and ordinary shares expected to be issued under the Company’s ESPP.

The Company has a choice to settle the conversion obligation under the 2023 Notes in cash, shares or any combination of the two. The Company utilizes the if-converted method to reflect the impact
of the conversion of the 2023 Notes, unless the result is anti-dilutive. This method assumes the conversion of the 2023 Notes into shares of the Company’s ordinary shares and reflects the elimination
of the interest expense related to the 2023 Notes.

The dilutive effect of the stock options, restricted stock units, preferred shares and ordinary shares expected to be issued under the Company’s ESPP has been calculated using the treasury stock
method. The dilutive effect of the PSUs will be calculated using the treasury stock method, if and when the contingent vesting condition is achieved.

A reconciliation of basic and diluted net (loss) income per share, together with the related shares outstanding in thousands for the years ended December 31, 2021, 2020 and 2019, is as follows:   

Net (Loss) Income Per Share:

Potential ordinary shares of 15,327, 14,915, and 16,740 were excluded from the calculation of weighted average shares for the years ended December 31, 2021, 2020 and 2019, respectively, because
either their effect was considered to be anti-dilutive or they were related to shares from PSUs for which the contingent vesting condition had not been achieved. For the years ended December 31,
2021 and 2019, the effects of dilutive securities were entirely excluded from the calculation of net (loss) income per share as a net loss was reported in these periods.

The  Company  has  determined  that  it  operates  in  one  segment,  the  development  and  commercialization  of  pharmaceutical  products,  including  controlled-release  therapeutic  products  based  on  its
proprietary polymer based technology. The Company’s Chief Operating Decision Maker is the CEO. The CEO reviews profit and loss information on a consolidated basis to assess performance and
make overall operating decisions as well as resource allocations. All products are included in one segment because the Company’s products have similar economic and other characteristics, including

Concentration of credit risk with respect to accounts receivable was limited due to the high credit quality comprising a significant portion of the Company’s customers. Management periodically
monitors the creditworthiness of the Company’s customers and believes that it has adequately provided for any exposure to potential credit loss.

Currently,  the  Company  is  working  with  contract  manufacturing  organizations  for  the  manufacture  of  FT218.  Additionally,  the  Company  purchases  raw  materials  used  in  FT218  from  a  limited
number of suppliers, including a single supplier for certain key ingredients.

the closing of the sale of the Hospital Products, the Deerfield MIPA (with respect to certain sections thereof) and the Royalty Agreement were assigned to the Exela Buyer. Pursuant to the Purchase
Agreement, the Exela Buyer assumed and will pay, perform, satisfy and discharge the liabilities and obligations of Avadel Legacy under the Deerfield Royalty Agreement for obligations that arise
after the Closing Date.

Prior to June 30, 2020, the Company was also party to a Royalty Agreement by and between itself, Avadel Legacy and Broadfin Healthcare Master Fund, Ltd. (the “Broadfin Royalty Agreement”). In
connection with the closing of the sale of the Hospital Products, the Broadfin Royalty Agreement was assigned to the Exela Buyer and the Exela Buyer assumed and shall pay, perform, satisfy and
discharge the liabilities and obligations of Avadel Legacy under the Broadfin Royalty Agreement for obligations that arise after the Closing Date.

Refer to Note 12: Contingent Consideration Payable for a summary of payments made for and changes to the fair value of the related party payable for the year ended December 31, 2019. Deerfield
and Broadfin disposed of their 2023 Notes and ordinary shares in the Company during the year ended December 31, 2020 and are no longer considered related parties for the years ended December
31, 2021 and 2020.

NOTE 23: Subsequent Events 

On  March  16,  2022,  Avadel  Finance  Cayman  Limited,  a  Cayman  Islands  exempted  company  and  an  indirect  wholly-owned  subsidiary  of  the  Company  (the  “Issuer”),  executed  an  agreement  to
exchange $117,375 of its 2023 Notes due February 1, 2023 (the “February 2023 Notes”) for a new series of its Exchangeable Senior Notes due October 2, 2023 (the “October 2023 Notes”) (the
“Exchange”). The remaining $26,375 aggregate principal amount of the February 2023 Notes will maintain a maturity date of February 1, 2023. Taking into consideration the Exchange and the
maturity date of the October 2023 Notes and based on the Company’s current plans, the Company has sufficient cash on hand and available liquidity to satisfy its obligations and fund working capital
needs for at least twelve months following the date of issuance of the Consolidated Financial Statements. The Company has a recent history of generating losses from operations including during
2021 and expects to continue generating losses over the next twelve months. Similar to other businesses in the Company’s industry and at its stage of development, the Company will continue in the
medium term to rely on external sources of capital to fund its business.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Avadel Pharmaceuticals plc

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Avadel Pharmaceuticals plc (the "Company") as of December 31, 2021 and 2020, the related consolidated statements of (loss)
income, comprehensive (loss) income, shareholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2021, and the related notes and the schedule listed in the
Index at Item 15 (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of
December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with accounting principles generally
accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of
December 31, 2021, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our
report dated March 16, 2022 expressed an adverse opinion on the Company's internal control over financial reporting
.
Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. 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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial
statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall  presentation  of  the  financial
statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to
accounts  or  disclosures  that  are  material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective,  or  complex  judgments.  We  determined  that  there  are  no  critical  audit
matters.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Avadel Pharmaceuticals plc

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Avadel Pharmaceuticals plc (the “Company”) as of December 31, 2021, based on criteria established in Internal Control — Integrated
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, because of the effect of the material weakness identified below on the
achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2021, based on criteria established in
Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year
ended December 31, 2021, of the Company and our report dated March 16, 2022, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting,
included  in  the  accompanying  Management’s  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.

Material Weakness

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material weakness of the Company’s
annual  or  interim  financial  statements  will  not  be  prevented  or  detected  on  a  timely  basis.  The  following  material  weakness  has  been  identified  and  included  in  management’s  assessment:
Management did not have a control to identify that they were in technical default of its 2023 convertible notes and owed 0.50% of additional interest due to the failure to remove a restrictive legend
from the 2023 convertible notes. This material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the consolidated financial statements as of
and for the year ended December 31, 2021, of the Company, and this report does not affect our report on such financial statements.

Item 9.         Changes in and Disagreements with Accountants on Accounting and Financial Disclosure. 

None.

Item 9A.    Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

As required by Rule 15d -15(b) of the Exchange Act, our management has evaluated, under the supervision and with the participation of our principal executive officer and principal financial officer,
the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Annual Report. Based on
that evaluation, our principal executive officer and principal financial officer concluded that as of the end of the period covered by this Annual Report our disclosure controls and procedures were not
effective due to the material weakness in our internal control over financial reporting described below.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of
1934, as amended. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements
in accordance with U.S. generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect all 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.

We assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In making this assessment, our management used the criteria set forth in Internal Control-
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management concluded that, as of December 31, 2021,
the Company’s internal control over financial reporting was not effective.

A  material  weakness  is  a  deficiency,  or  combination  of  deficiencies,  in  internal  control  over  financial  reporting,  such  that  there  is  a  reasonable  possibility  that  a  material  misstatement  of  the
company’s annual or interim financial statements will not be prevented or detected on a timely basis.

Material Weakness in Internal Control Over Financial Reporting

During the Company’s fiscal 2021 financial statement close process, management identified a deficiency in the design of internal control over financial reporting related to its February 2023 Notes
indenture. Specifically, management did not have a control to identify that we were in technical default of the February 2023 Notes and owed 0.50% of additional interest on the February 2023 Notes
due to not removing a restrictive legend from the February 2023 Notes 365 days following the original issuance of the February 2023 Notes on February 16, 2018. The Company cured the default
through payment of the additional interest in March 2022.

The effectiveness of our internal control over financial reporting as of December 31, 2021 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in
their report included in this Annual Report. This report contains an adverse opinion on the effectiveness of our internal control over financial reporting.

Remediation of Material Weakness

Once the material weakness was identified, we developed and implemented a remediation plan that includes the implementation of additional control procedures surrounding timely and periodic
evaluation of all terms of our debt agreement and the associated calculation of interest expense in accordance with the terms of such debt agreement to ensure the completeness and accuracy of the
calculation and timely payment of interest expense, classification of debt and compliance with terms of the debt agreement.

We are committed to maintaining a strong internal control environment and have fully implemented measures designed to help ensure that the control deficiency contributing to the material weakness
is remediated. However, there cannot be any assurance that these remediation efforts will be successful or that our internal control over financial reporting will be effective as a result of these efforts.
The material weakness will be fully remediated when, we have determined, through testing, these controls have operated effectively for a sufficient period of time.

-109-

Other Changes in Internal Control Over Financial Reporting

Except as noted above, there have been no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange
Act during the quarter ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

AVADEL PHARMACEUTICALS PLC

2021 INDUCEMENT PLAN

SECTION 1.  GENERAL PURPOSE OF THE PLAN; DEFINITIONS

The name of the plan is the Avadel Pharmaceuticals plc 2021 Inducement Plan (the “Plan”). The purpose of the Plan is to enable Avadel Pharmaceuticals plc,

an Irish public limited company (the “Company”) to grant equity awards to induce highly-qualified prospective officers and employees who are not currently
employed by the Company and its Affiliates to accept employment and provide them with a proprietary interest in the Company. It is anticipated that providing such
persons with a direct stake in the Company’s welfare will assure a closer identification of their interests with those of the Company and its shareholders, thereby
stimulating their efforts on the Company’s behalf and strengthening their desire to remain with the Company. The Company intends that the Plan be reserved for
persons to whom the Company may issue securities without shareholder approval as an inducement pursuant to Rule 5635(c)(4) of the Marketplace Rules of
NASDAQ Stock Market, Inc.

The following terms shall be defined as set forth below:

“Exchange Act” means the United States Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder.

New York Stock Exchange or another securities exchange or traded on any established market, the determination shall be made by reference to market quotations. If

    3
ACTIVE/113395993.5

(i)

(ii)

to select the individuals to whom Awards may from time to time be granted;

to determine the time or times of grant, and the extent, if any, of Non-Qualified Options, Share Appreciation Rights, Restricted Share Awards,

Restricted Share Units, Unrestricted Share Awards, and Dividend Equivalent Rights, or any combination of the foregoing, granted to any one or more grantees;

(iii)

to determine the number of Shares to be covered by any Award and to determine whether any Award shall pertain to Shares or ADSs;

(iv)

to determine and modify from time to time the terms and conditions, including restrictions, not inconsistent with the terms of the Plan, of any

Award, which terms and conditions may differ among individual Awards and grantees, and to approve the forms of Award Certificates;

(v)

to accelerate at any time the exercisability or vesting of all or any portion of any Award;

(vi)

subject to the provisions of Section 5(c), to extend at any time the period in which Options may be exercised; and

(vii)

at any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and for its own acts and proceedings as

it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including related written instruments); to make all determinations it deems
advisable for the administration of the Plan; to decide all disputes arising in connection with the Plan; and to otherwise supervise the administration of the Plan.

All decisions and interpretations of the Administrator shall be binding on all persons, including the Company and Plan grantees.

(c)

Award Certificate. Awards under the Plan shall be evidenced by Award Certificates that set forth the terms, conditions and limitations for each Award

which may include, without limitation, the term of an Award and the provisions applicable in the event employment or service terminates.

(d)

(e)

Reserved.

Indemnification. Neither the Board nor the Administrator, nor any member of either or any delegate thereof, shall be liable for any act, omission,

interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Administrator (and any delegate
thereof) shall be entitled in all cases to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including, without
limitation, reasonable attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or under the Company’s constitution or any directors’
and officers’ liability insurance coverage which may be in effect from time to time and/or any indemnification agreement between such individual and the Company.

(f)

Non-U.S. Award Recipients. Notwithstanding any provision of the Plan to the contrary, in order to comply with the laws of countries other than the
U.S. in which the Company and its Subsidiaries operate or have employees or other individuals eligible for Awards, the Administrator, in its sole discretion, shall
have the power and authority to: (i) determine which Subsidiaries shall be covered by the Plan; (ii) determine which individuals outside the United

    4
ACTIVE/113395993.5

States are eligible to participate in the Plan; (iii) modify the terms and conditions of any Award granted to individuals outside the United States to comply with
applicable foreign laws; (iv) establish subplans and modify exercise procedures and other terms and procedures, to the extent the Administrator determines such
actions to be necessary or advisable (and such subplans and/or modifications shall be attached to this Plan as appendices); provided, however, that no such subplans
and/or modifications shall increase the share limitations contained in Section 3(a) hereof; and (v) take any action, before or after an Award is made, that the
Administrator determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals.
Notwithstanding the foregoing, the Administrator may not take any actions hereunder, and no Awards shall be granted, that would violate the Exchange Act or any
other applicable United States securities law, the Code, any other applicable United States governing statute or law, or any applicable Irish law.

SECTION 3.  STOCK ISSUABLE UNDER THE PLAN; MERGERS; SUBSTITUTION

(a)

Stock Issuable. The maximum number of Shares reserved and available for issuance under the Plan shall be 1,500,000 Shares, subject to adjustment as
provided in this Section 3. For purposes of this limitation, the Shares underlying any awards under the Plan that are forfeited, canceled or otherwise terminated (other
than by exercise) shall be added back to the Shares available for issuance under the Plan. Notwithstanding the foregoing, the following Shares shall not be added to
the Shares authorized for grant under the Plan: (i) Shares tendered or held back upon exercise of an Option or settlement of an Award to cover the exercise price or
tax withholding, and (ii) Shares subject to a Share Appreciation Right that are not issued in connection with the share settlement of the Share Appreciation Right
upon exercise thereof. In the event the Company repurchases Shares on the open market, such Shares shall not be added to the Shares available for issuance under the
Plan. Subject to such overall limitations, Shares may be issued up to such maximum number pursuant to any type or types of Award. The Shares available for
issuance under the Plan may be authorized but unissued Shares or Shares reacquired by the Company.

(b)

Changes in Shares. Subject to Section 3(c) hereof, if, as a result of any reorganization, recapitalization, reclassification, share dividend, share split,
reverse share split or other similar change in the Company’s capital, the outstanding Shares are increased or decreased or are exchanged for a different number or
kind of shares or other securities of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are
distributed with respect to such Shares or other securities, or, if, as a result of any Sale Event, or sale of all or substantially all of the assets of the Company, the
outstanding Shares are converted into or exchanged for securities of the Company or any successor entity (or a parent or subsidiary thereof), the Administrator shall
make an appropriate or proportionate adjustment in (i) the maximum number of Shares reserved for issuance under the Plan, (ii) the number and kind of Shares or
other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per Share subject to each outstanding Restricted Share
Award, and (iv) the exercise price for each Share subject to any then outstanding Options and Share Appreciation Rights under the Plan, without changing the
aggregate exercise price (i.e., the exercise price multiplied by the number of shares subject to Options and Share Appreciation Rights) as to which such Options and
Share Appreciation Rights remain exercisable. The Administrator shall also make equitable or proportionate adjustments in the number of shares subject to
outstanding Awards and the exercise price and the terms of outstanding Awards to take into consideration cash dividends paid other than in the ordinary course or any
other extraordinary corporate event. The adjustment by the Administrator shall be final, binding and conclusive. No fractional Shares shall be issued under the Plan
resulting from any such adjustment, but the Administrator in its discretion may make a cash payment in lieu of fractional Shares.

    5
ACTIVE/113395993.5

(c)

Sale Events. In the case of and subject to the consummation of a Sale Event, the parties thereto may cause the assumption or continuation of Awards

theretofore granted by the successor entity, or the substitution of such Awards with new Awards of the successor entity or parent thereof, with appropriate adjustment
as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree. To the extent the parties to such Sale Event do not
provide for the assumption, continuation or substitution of Awards, upon the effective time of the Sale Event, the Plan and all outstanding Awards granted hereunder
shall terminate. In the event of such termination, (i) the Company shall have the option (in its sole discretion) to make or provide for a payment, in cash or in kind, to
the grantees holding Options and Share Appreciation Rights, in exchange for the cancellation thereof, in an amount equal to the difference between (A) the Sale Price
multiplied by the number of Shares subject to outstanding Options and Share Appreciation Rights (to the extent then vested and exercisable at prices not in excess of
the Sale Price) and (B) the aggregate exercise price of all such outstanding Options and Share Appreciation Rights (provided that, in the case of an Option or Share
Appreciation Right with an exercise price equal to or greater than the Sale Price, such Option or Share Appreciation Right shall be cancelled for no consideration); or
(ii) each grantee shall be permitted, within a specified period of time prior to the consummation of the Sale Event as determined by the Administrator, to exercise all
outstanding Options and Share Appreciation Rights (to the extent then vested and exercisable) held by such grantee. The Company shall also have the option (in its
sole discretion) to make or provide for a payment, in cash or in kind, to the grantees holding other Awards in an amount equal to the Sale Price multiplied by the
number of vested Shares under such Awards.

SECTION 4.  ELIGIBILITY

Grantees under the Plan will be such employees of the Company and its Affiliates as to whom the Company may issue securities without shareholder
approval in accordance with Rule 5635(c)(4) of the Marketplace Rules of NASDAQ Stock Market, Inc. as selected from time to time by the Administrator in its sole
discretion; provided that Awards may not be granted to employees who are providing services only to any “parent” of the Company, as such term is defined in Rule
405 of the Act, unless (i) the stock underlying the Awards is treated as “service recipient stock” under Section 409A or (ii) the Company has determined that such
Awards are exempt from or otherwise comply with Section 409A.

SECTION 5.  OPTIONS

(a)

Award of Options. The Administrator may grant Options under the Plan. Any Option granted under the Plan shall be a Non-Qualified Option, and

shall be in such form as the Administrator may from time to time approve.

Options granted pursuant to this Section 5 shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not

inconsistent with the terms of the Plan, as the Administrator shall deem desirable. .

(b)

Exercise Price. The exercise price per Share covered by an Option granted pursuant to this Section 5 shall be determined by the Administrator at the

time of grant but shall not be less than 100 percent of the Fair Market Value on the date of grant. Notwithstanding the foregoing, Options may be granted with an
exercise price per Share that is less than 100 percent of the Fair Market Value on the date of grant (i) to individuals who are not subject to U.S. income tax on the date
of grant or (ii) if the Option is otherwise compliant with Section 409A.

(c)

Option Term. The term of each Option shall be fixed by the Administrator, but no Option shall be exercisable more than ten years after the date the

Option is granted. Where an Option is granted with an exercise price per share that is less than 100 percent of the Fair Market

    6
ACTIVE/113395993.5

Value on the date of grant to an individual who is tax resident in Ireland, the Option shall lapse if not exercised within 7 years of the date of grant.

(d)

Exercisability; Rights of a Shareholder. Options shall become exercisable at such time or times, whether or not in installments, as shall be determined
by the Administrator at or after the grant date. The Administrator may at any time accelerate the exercisability of all or any portion of any Option. An optionee shall
have the rights of a shareholder only as to Shares acquired upon the exercise of an Option and not as to unexercised Options.

(e)

Method of Exercise. Options may be exercised in whole or in part, by giving written or electronic notice of exercise to the Company, specifying the
number of Shares to be purchased. Payment of the purchase price may be made by one or more of the following methods except to the extent otherwise provided in
the Award Certificate:

(i)

In cash, by certified or bank check or other instrument acceptable to the Administrator;

subject to restrictions under any Company plan. Such surrendered Shares shall be valued at Fair Market Value on the exercise date;

(ii)

Through the delivery (or attestation to the ownership following such procedures as the Company may prescribe) of Shares that are not then

(iii)

By the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly

deliver to the Company cash or a check payable and acceptable to the Company for the purchase price; provided that in the event the optionee chooses to pay the
purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as
the Company shall prescribe as a condition of such payment procedure; or

(iv)

By a “net exercise” arrangement pursuant to which the Company will reduce the number of Shares issuable upon exercise by the largest whole
number of Shares with a Fair Market Value that does not exceed the aggregate exercise price. Where newly issued Shares are to be delivered in this way, the Affiliate
which employs the grantee, if so agreed with the Company, shall pay to the Company such price as is at least equal to the aggregate nominal value of the Shares
issued.

Payment instruments will be received subject to collection. The transfer to the optionee on the records of the Company or of the transfer agent of the Shares to be
purchased pursuant to the exercise of an Option will be contingent upon receipt from the optionee (or a purchaser acting in his or her stead in accordance with the
provisions of the Option) by the Company of the full purchase price for such shares and the fulfillment of any other requirements contained in the Award Certificate
or applicable provisions of laws (including the satisfaction of any withholding taxes that the Company is obligated to withhold with respect to the optionee). In the
event an optionee chooses to pay the purchase price by previously-owned Shares through the attestation method, the number of Shares transferred to the optionee
upon the exercise of the Option shall be net of the number of attested Shares. In the event that the Company establishes, for itself or using the services of a third
party, an automated system for the exercise of Options, such as a system using an internet website or interactive voice response, then the paperless exercise of
Options may be permitted through the use of such an automated system.

SECTION 6.  SHARE APPRECIATION RIGHTS

(a)

Award of Share Appreciation Rights. The Administrator may grant Share Appreciation Rights under the Plan. A Share Appreciation Right is an Award

entitling the

    7
ACTIVE/113395993.5

recipient to receive Shares (or cash, to the extent explicitly provided for in the applicable Award Certificate) having a value equal to the excess of the Fair Market
Value of a Share on the date of exercise over the exercise price of the Share Appreciation Right multiplied by the number of Shares with respect to which the Share
Appreciation Right shall have been exercised.

(b)

Exercise Price of Share Appreciation Rights. The exercise price of a Share Appreciation Right shall not be less than 100 percent of the Fair Market

Value of a Share on the date of grant.

(c)

Grant and Exercise of Share Appreciation Rights. Share Appreciation Rights may be granted by the Administrator independently of any Option

granted pursuant to Section 5 of the Plan.

(d)

Terms and Conditions of Share Appreciation Rights. Share Appreciation Rights shall be subject to such terms and conditions as shall be determined on

the date of grant by the Administrator. The term of a Share Appreciation Right may not exceed ten years. The terms and conditions of each such Award shall be
determined by the Administrator, and such terms and conditions may differ among individual Awards and grantees.

SECTION 7.  RESTRICTED SHARE AWARDS

(a)

Nature of Restricted Share Awards. The Administrator may grant Restricted Share Awards under the Plan. A Restricted Share Award is any Award of

Restricted Shares subject to such restrictions and conditions as the Administrator may determine at the time of grant. Conditions may be based on continuing
employment (or other Service Relationship) and/or achievement of pre-established performance goals and objectives.

(b)

Rights as a Shareholder. Upon the grant of the Restricted Share Award and payment of any applicable purchase price, a grantee shall have the rights of
a shareholder with respect to the voting of the Restricted Shares and receipt of dividends; provided that any dividends paid by the Company during the vesting period
shall accrue and shall not be paid to the grantee until and to the extent the Restricted Shares vest. Unless the Administrator shall otherwise determine, (i)
uncertificated Restricted Shares shall be accompanied by a notation on the records of the Company or the transfer agent to the effect that they are subject to forfeiture
until such Restricted Shares are vested as provided in Section 7(d) below, and (ii) certificated Restricted Shares shall remain in the possession of the Company until
such Restricted Shares are vested as provided in Section 7(d) below, and the grantee shall be required, as a condition of the grant, to deliver to the Company such
instruments of transfer as the Administrator may prescribe.

(c)

Restrictions. Restricted Shares may not be sold, assigned, transferred, pledged or otherwise encumbered or disposed of except as specifically provided

herein or in the Restricted Share Award Certificate. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section
15 below, in writing after the Award is issued, if a grantee’s employment (or other Service Relationship) with the Company and its Subsidiaries terminates for any
reason, any Restricted Shares that have not vested at the time of termination shall automatically and without any requirement of notice to such grantee from or other
action by or on behalf of, the Company be deemed to have been reacquired by the Company at its original purchase price (if any) from such grantee or such grantee’s
legal representative simultaneously with such termination of employment (or other Service Relationship), and thereafter shall cease to represent any ownership of the
Company by the grantee or rights of the grantee as a shareholder. Following such deemed reacquisition of Restricted Shares that are represented by physical
certificates, a grantee shall surrender such certificates to the Company upon request without consideration.

ACTIVE/113395993.5

(d)

Vesting and payment of Restricted Shares. The Administrator at the time of grant shall specify the date or dates and/or the attainment of pre-

established performance goals, objectives and other conditions on which the non-transferability of the Restricted Shares and the Company’s right of repurchase or
forfeiture shall lapse. Subsequent to such date or dates and/or the attainment of such pre-established performance goals, objectives and other conditions, the Shares
on which all restrictions have lapsed shall no longer be Restricted Shares and shall be deemed “vested.” Where newly issued Shares are to be delivered on the vesting
of a Restricted Share Award, the Affiliate which employs the grantee, if so agreed with the Company, shall pay to the Company such price as is at least equal to the
aggregate nominal value of the Shares the subject of the Restricted Share Award.

SECTION 8.  RESTRICTED SHARE UNITS

(a)

Nature of Restricted Share Units. The Administrator may grant Restricted Share Units under the Plan. A Restricted Share Unit is an Award of stock
units that may be settled in Shares (or cash, to the extent explicitly provided for in the Award Certificate) upon the satisfaction of such restrictions and conditions at
the time of grant. Conditions may be based on continuing employment (or other Service Relationship) and/or achievement of pre-established performance goals and
objectives. The terms and conditions of each such Award shall be determined by the Administrator, and such terms and conditions may differ among individual
Awards and grantees. Except in the case of Restricted Share Units with a deferred settlement date that complies with Section 409A, at the end of the vesting period,
the Restricted Share Units, to the extent vested, shall be settled in the form of Shares. Restricted Share Units with deferred settlement dates are subject to Section
409A and shall contain such additional terms and conditions as the Administrator shall determine in its sole discretion in order to comply with the requirements of
Section 409A.

(b)

Rights as a Shareholder. A grantee shall have the rights as a shareholder only as to Shares acquired by the grantee upon settlement of Restricted Share

Units; provided, however, that the grantee may be credited with Dividend Equivalent Rights with respect to the stock units underlying his or her Restricted Share
Units, subject to the provisions of Section 10 and such terms and conditions as the Administrator may determine. Where newly issued Shares are to be delivered on
the vesting of a Restricted Share Unit, the Affiliate which employs the grantee, if so agreed with the Company, shall pay to the Company such price as is at least
equal to the aggregate nominal value of the Shares the subject of the Restricted Share Unit.

(c)

Termination. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 15 below, in writing after

the Award is issued, a grantee’s right in all Restricted Share Units that have not vested shall automatically terminate upon the grantee’s termination of employment
(or cessation of Service Relationship) with the Company and its Subsidiaries for any reason.

SECTION 9.  UNRESTRICTED SHARE AWARDS

Grant or Sale of Unrestricted Shares. The Administrator may grant (or sell at par value or such higher purchase price determined by the Administrator) an

Unrestricted Share Award under the Plan. An Unrestricted Share Award is an Award pursuant to which the grantee may receive Shares free of any restrictions under
the Plan. Unrestricted Share Awards may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to such grantee.

ACTIVE/113395993.5

SECTION 10. 

DIVIDEND EQUIVALENT RIGHTS

(a)

Dividend Equivalent Rights. The Administrator may grant Dividend Equivalent Rights under the Plan. A Dividend Equivalent Right is an Award

entitling the grantee to receive credits based on cash dividends that would have been paid on the Shares specified in the Dividend Equivalent Right (or other Award to
which it relates) if such shares had been issued to the grantee. A Dividend Equivalent Right may be granted hereunder to any grantee as a component of an award of
Restricted Share Units or as a freestanding award. The terms and conditions of Dividend Equivalent Rights shall be specified in the Award Certificate. Dividend
equivalents credited to the holder of a Dividend Equivalent Right may be paid currently or may be deemed to be reinvested in additional Shares, which may
thereafter accrue additional equivalents. Any such reinvestment shall be at Fair Market Value on the date of reinvestment or such other price as may then apply under
a dividend reinvestment plan sponsored by the Company, if any. Dividend Equivalent Rights may be settled in cash or Shares or a combination thereof, in a single
installment or installments. A Dividend Equivalent Right granted as a component of an Award of Restricted Share Units shall provide that such Dividend Equivalent
Right shall be settled only upon settlement or payment of, or lapse of restrictions on, such other Award, and that such Dividend Equivalent Right shall expire or be
forfeited or annulled under the same conditions as such other Award.

(b)

Termination. Except as may otherwise be provided by the Administrator either in the Award Certificate or, subject to Section 15 below, in writing after
the Award is issued, a grantee’s rights in all Dividend Equivalent Rights shall automatically terminate upon the grantee’s termination of employment (or cessation of
Service Relationship) with the Company and its Subsidiaries for any reason.

SECTION 11. 

TRANSFERABILITY OF AWARDS

(a)

Transferability. Except as provided in Section 11(b) below, during a grantee’s lifetime, his or her Awards shall be exercisable only by the grantee, or
by the grantee’s legal representative or guardian in the event of the grantee’s incapacity. No Awards shall be sold, assigned, transferred or otherwise encumbered or
disposed of by a grantee other than by will or by the laws of descent and distribution or pursuant to a domestic relations order. No Awards shall be subject, in whole
or in part, to attachment, execution, or levy of any kind, and any purported transfer in violation hereof shall be null and void.

(b)

Administrator Action. Notwithstanding Section 11(a), the Administrator, in its discretion, may provide either in the Award Certificate regarding a

given Award or by subsequent written approval that the grantee (who is an employee or director) may transfer his or her Non-Qualified Options to his or her
immediate family members, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, provided that the
transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award. In no event may an Award be
transferred by a grantee for value.

(c)

Family Member. For purposes of Section 11(b), “family member” shall mean a grantee’s child, stepchild, grandchild, parent, stepparent, grandparent,

spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive
relationships, any person sharing the grantee’s household (other than a tenant of the grantee), a trust in which these persons (or the grantee) have more than 50
percent of the beneficial interest, a foundation in which these persons (or the grantee) control the management of assets, and any other entity in which these persons
(or the grantee) own more than 50 percent of the voting interests.

    10
ACTIVE/113395993.5

(d)

Designation of Beneficiary. To the extent permitted by the Company, each grantee to whom an Award has been made under the Plan may designate a
beneficiary or beneficiaries to exercise any Award or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on
a form provided for that purpose by the Administrator and shall not be effective until received by the Administrator. If no beneficiary has been designated by a
deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary shall be the grantee’s estate.

SECTION 12. 

TAX WITHHOLDING

(a)

Payment by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any Share or other amount received thereunder

first becomes includable in the gross income of the grantee for income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator
regarding payment of, any Federal, state, or local taxes of any kind required by law to be withheld by the Company with respect to such income. The Company and
its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to the grantee. The
Company’s obligation to deliver evidence of book entry (or stock certificates) to any grantee is subject to and conditioned on tax withholding obligations being
satisfied by the grantee.

(b)

Payment in Stock. The Administrator may require the Company’s tax withholding obligation to be satisfied, in whole or in part, by the Company

withholding from Shares to be issued pursuant to any Award a number of Shares with an aggregate Fair Market Value (as of the date the withholding is effected) that
would satisfy the withholding amount due; provided, however, that the amount withheld does not exceed the maximum statutory tax rate or such lesser amount as is
necessary to avoid liability accounting treatment. For purposes of share withholding, the Fair Market Value of withheld shares shall be determined in the same
manner as the value of Shares includible in income of the grantees. The Administrator may also require the Company’s tax withholding obligation to be satisfied, in
whole or in part, by an arrangement whereby a certain number of Shares issued pursuant to any Award are immediately sold and proceeds from such sale are remitted
to the Company in an amount that would satisfy the withholding amount due.

SECTION 13. 

SECTION 409A AWARDS

Awards are intended to be exempt from Section 409A to the greatest extent possible and to otherwise comply with Section 409A. The Plan and all Awards

shall be interpreted in accordance with such intent. To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the
meaning of Section 409A (a “409A Award”), the Award shall be subject to such additional rules and requirements as specified by the Administrator from time to time
in order to comply with Section 409A. In this regard, if any amount under a 409A Award is payable upon a “separation from service” (within the meaning of Section
409A) to a grantee who is then considered a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is
the earlier of (i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s death, but only to the extent such delay is necessary to prevent
such payment from being subject to interest, penalties and/or additional tax imposed pursuant to Section 409A. Further, the settlement of any 409A Award may not
be accelerated except to the extent permitted by Section 409A.

    11
ACTIVE/113395993.5

SECTION 14.  TERMINATION OF SERVICE RELATIONSHIP, TRANSFER, LEAVE OF ABSENCE, ETC.

(a)

Termination of Service Relationship. If the grantee’s Service Relationship is with an Affiliate and such Affiliate ceases to be an Affiliate, the grantee

shall be deemed to have terminated his or her Service Relationship for purposes of the Plan.

(b)

For purposes of the Plan, the following events shall not be deemed a termination of a Service Relationship:

(i)

a transfer to the employment of the Company from an Affiliate or from the Company to an Affiliate, or from one Affiliate to another; or

(ii)

an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the employee’s right to re-
employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise
so provides in writing.

SECTION 15. 

AMENDMENTS AND TERMINATION

The Board may, at any time, amend or discontinue the Plan and the Administrator may, at any time, amend or cancel any outstanding Award for the purpose
of satisfying changes in law or for any other lawful purpose, but no such action shall materially and adversely affect rights under any outstanding Award without the
holder’s consent. Except as provided in Section 3(b) or 3(c), without prior shareholder approval, in no event may the Administrator exercise its discretion to reduce
the exercise price of outstanding Options or Share Appreciation Rights or effect repricing through cancellation and re-grants or cancellation of Options or Share
Appreciation Rights in exchange for cash or other Awards. Nothing in this Section 15 shall limit the Administrator’s authority to take any action permitted pursuant
to Section 3(b) or 3(c).

SECTION 16. 

STATUS OF PLAN

With respect to the portion of any Award that has not been exercised and any payments in cash, Shares or other consideration not received by a grantee, a

grantee shall have no rights greater than those of a general creditor of the Company unless the Administrator shall otherwise expressly determine in connection with
any Award or Awards. In its sole discretion, the Administrator may authorize the creation of trusts or other arrangements to meet the Company’s obligations to
deliver Shares or make payments with respect to Awards hereunder, provided that the existence of such trusts or other arrangements is consistent with the foregoing
sentence.

SECTION 17. 

GENERAL PROVISIONS

(a)

No Distribution. The Administrator may require each person acquiring Shares pursuant to an Award to represent to and agree with the Company in

writing that such person is acquiring the shares without a view to distribution thereof.

(b)

Issuance of Stock. To the extent certificated, stock certificates to grantees under this Plan shall be deemed delivered for all purposes when the

Company or a stock transfer agent of the Company shall have mailed such certificates, addressed to the grantee, at the grantee’s last known address on file with the
Company. Uncertificated Shares shall be deemed delivered for all purposes when the Company or a Share transfer agent of the Company shall have given to the
grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company,
notice of issuance and recorded the issuance in its records (which may include electronic “book entry” records).

    12
ACTIVE/113395993.5

Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any evidence of book entry or certificates evidencing Shares
pursuant to the exercise or settlement of any Award, unless and until the Administrator has determined, with advice of counsel (to the extent the Administrator deems
such advice necessary or advisable), that the issuance and delivery is in compliance with all applicable laws, regulations of governmental authorities and, if
applicable, the requirements of any exchange on which the Shares are listed, quoted or traded. Any Shares issued pursuant to the Plan shall be subject to any stop-
transfer orders and other restrictions as the Administrator deems necessary or advisable to comply with Federal, state or foreign jurisdiction, securities or other laws,
rules and quotation system on which the Shares are listed, quoted or traded. The Administrator may place legends on any Share certificate or notations on any book
entry to reference restrictions applicable to the Shares. In addition to the terms and conditions provided herein, the Administrator may require that an individual make
such reasonable covenants, agreements, and representations as the Administrator, in its discretion, deems necessary or advisable in order to comply with any such
laws, regulations, or requirements. The Administrator shall have the right to require any individual to comply with any timing or other restrictions with respect to the
settlement or exercise of any Award, including a window-period limitation, as may be imposed in the discretion of the Administrator.

(c)

Shareholder Rights. Until Shares are deemed delivered in accordance with Section 17(b), no right to vote or receive dividends or any other rights of a
shareholder will exist with respect to Shares to be issued in connection with an Award, notwithstanding the exercise of an Option or any other action by the grantee
with respect to an Award.

(d)

Other Compensation Arrangements; No Employment Rights. Nothing contained in this Plan shall prevent the Board from adopting other or additional
compensation arrangements, including trusts, and such arrangements may be either generally applicable or applicable only in specific cases. The adoption of this Plan
and the grant of Awards do not confer upon any employee any right to continued employment with the Company or any Subsidiary.

(e)

Payment of Nominal Value. Notwithstanding any other provision of this Plan, no Shares in the authorized but unissued share capital of the Company

shall be issued in settlement of an Award unless they are paid-up, on issuance, to at least their nominal value. If the Board determines that an Award is to be settled by
the issuance of authorized but unissued Shares, the Board may decide that the Shares so issued will be: (1) paid-up from the exercise price (if any); (2) otherwise
paid-up by the grantee; (3) subject to applicable law, paid-up by the Company from distributable profits or other reserves which may be applied for that purpose; or
(4) subject to applicable law, paid-up by a subsidiary of the Company or by another person.

(f)

Trading Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading policies and

procedures, as in effect from time to time.

(g)

(h)

Clawback Policy. Awards under the Plan shall be subject to the Company’s clawback policy, as in effect from time to time.

Concert-Party Restrictions under the Irish Takeover Rules. In the event that any individual who is eligible to receive an Award is, or is presumed to be,

a “person acting in concert” for the purposes of the Irish Takeover Rules, and the grant, exercise, vesting, settlement or any other action in relation to an Award to
such individual may, in the reasonable opinion of the Administrator, result in the individual and/or any person acting, or presumed to be acting, in concert with such
individual (“Participant”) becoming obliged under the Irish Takeover Rules to make an offer for the Company under Rule 9 of the Irish Takeover Rules (“a Concert-
Party

    13
ACTIVE/113395993.5

Offer”), the Administrator may decide that either (i) such grant, exercise, vesting, settlement or other action in relation to such individual or Participant shall not take
effect unless the Company is in receipt of a confirmation, direction or ruling from the Irish Takeover Panel that satisfies the Board that such grant, exercise, vesting,
settlement or other action would not result in an obligation to make a Concert-Party Offer; or the Shares which are to be delivered on the vesting or settlement of the
relevant Award shall not have any voting rights. If the Administrator determines that the exercise or settlement of any such Award by way of the issuance of Shares is
not possible or desirable, it may determine that such Award shall be settled in cash, on such conditions as the Administrator may determine.

SECTION 18. 

EFFECTIVE DATE OF PLAN

This Plan shall become effective immediately upon approval by the Board.

SECTION 19. 

GOVERNING LAW

This Plan and all Awards and actions taken thereunder shall be governed by, and construed in accordance with, the General Corporation Law of the State of
Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal laws of the State of
Delaware, applied without regard to conflict of law principles.

March 16, 2022

Avadel Finance Cayman Limited
c/o Avadel Pharmaceuticals plc
10 Earlsfort Terrace
Dublin 2, Ireland
D02 T380
Attention: General Counsel

Re:    Exchange for Avadel Finance Cayman Limited Exchangeable Senior Notes due 2023

Ladies and Gentlemen:

Avadel Finance Cayman Limited, a Cayman Islands exempted company limited by shares (the “Company”), is offering a new series of its Exchangeable Senior Notes due 2023
(the “New Notes”).  The  New  Notes  will  be  fully  and  unconditionally  guaranteed  on  a  senior  unsecured  basis  (the  “Guarantee”)  by  Avadel  Pharmaceuticals  plc,  a  public  limited
company incorporated under the laws of Ireland and the parent company of the Company (“Parent”). The New Notes will be exchangeable into cash, American Depositary Shares
(“ADSs”), each representing, as of the date hereof, one ordinary share of Parent, nominal value $0.01 per share (the “Ordinary Shares” and such ADSs into which the New Notes
are exchangeable, the “Underlying ADSs”), or a combination of cash and Underlying ADSs, at the Company’s election. Any ADSs to be issued upon conversion of the New Notes
are to be issued pursuant to, and in accordance with the applicable procedures of, the Deposit Agreement, dated as of January 3, 2017, among Parent, The Bank of New York
Mellon, as depositary (the “Depositary”), and the holders and beneficial owners of the ADSs issued under such agreement, as supplemented by a letter agreement, dated as of
February 16, 2018, between Parent and the Depositary and as further supplemented by a letter agreement to be dated the Closing Date (as defined below), between Parent and the
Depositary (the “Deposit Agreement”).

The  undersigned  (the  “Investor”),  for  itself  and,  on  behalf  of  the  accounts  (if  any)  listed  on  Exhibit A  hereto,  for  whom  the  Investor  has  been  duly  authorized  to  enter  into  the
Exchange (as defined below) (each, including the Investor if it is listed on Exhibit A, an “Exchanging Holder”), shall exchange 4.50% Convertible Senior Notes due 2023 (CUSIP:
05337YAA6 or 05337YAB4) of the Company (the “Old Notes”) for an amount of (i) New Notes and (ii) cash, each as set forth herein (the “Exchange”), pursuant and subject to the
terms and conditions set forth in this agreement (this “Exchange Agreement”). Reference is made to the Indenture (the “Old Notes Indenture”), dated February 16, 2018, by and
among the Company, Parent and The Bank of New York Mellon, as Trustee (the “Old Notes Trustee”), which governs the Old Notes.

The Exchanging Holders (including the Investor, as applicable) are referred to collectively as the “Purchasers,” and each Purchaser (other than the Investor) is referred to herein as
an “Account.”

The  Investor  and  each  Account  understands  that  the  Exchange  is  being  made  without  registration  under  the  Securities  Act  of  1933,  as  amended  (the  “Securities Act”),  or  any
securities laws of any state of the United States or of any other jurisdiction, and that the Exchange is only being made to investors who are “qualified institutional buyers” (as defined
in Rule 144A under the Securities Act) in reliance upon an exemption from registration under the Securities Act. The Exchange is described in, and is being made pursuant to, the
draft Indenture relating to the New Notes (the “Indenture”) to be entered into as of the Closing Date (as defined below) among the Company, Parent and The Bank of New York
Mellon, as Trustee (the “New Notes Trustee”), as supplemented by the Pricing Term Sheet, dated as of the date hereof (the “Pricing Term Sheet” and, together with the Indenture
and the Guarantee, the “Transaction Documents”).

1. The Exchange.  On  the  basis  of  the  representations,  warranties  and  agreements  contained  in  this  Exchange  Agreement  and  subject  to  the  terms  and  conditions  of  this
Exchange Agreement, each of the Exchanging Holders hereby agrees to deliver, assign and transfer to the Company all right, title and interest in the aggregate principal
amount of Old Notes for such Exchanging Holder set forth in column 2 of Exhibit A hereto (such aggregate principal amount of Old Notes, the “Exchanged Old Notes”) in
exchange for (i) New Notes having an aggregate principal amount, for each Exchanging Holder, as set forth in Exhibit A (such aggregate principal amount of New Notes, the
“Exchanged  New  Notes”)  and  (ii)  an  amount  of  cash  as  set  forth  in  Exhibit  A  (such  aggregate  principal  amount  of  cash,  the  “Cash  Consideration”  and  the  Cash
Consideration,

ACTIVE/115855038.2

together  with  the  Exchanged  New  Notes,  the  “Exchange  Consideration”),  and  the  Company  agrees  to  issue  such  Exchanged  New  Notes  and  deliver  such  Cash
Consideration to the Exchanging Holders in exchange for such Exchanged Old Notes.

For the avoidance of doubt, Exchanged New Notes will be issued in denominations of $200,000 principal amount and integral multiples of $1,000 in excess thereof, and the
Company will not make any separate cash payment in respect of rounded amounts, interest (including Additional Interest (as defined in the Old Notes Indenture)) accrued
and unpaid to the Closing Date (as defined below) or Defaulted Amounts for the Exchanged Old Notes. Instead, such amounts will be deemed to be paid in full rather than
cancelled,  extinguished  or  forfeited  upon  exchange  of  the  Exchanged  Old  Notes  for  the  Exchange  Consideration.  Subject  to  the  terms  and  conditions  of  this  Exchange
Agreement,  the  Investor,  on  behalf  of  itself  and  each  Exchanging  Holder,  hereby  (a)  waives  any  and  all  other  rights  with  respect  to  such  Exchanged  Old  Notes,  and
(b) releases and discharges the Company and Parent from any and all claims the Investor and any other Exchanging Holder may now have, or may have in the future,
arising out of, or related to, such Exchanged Old Notes, including, without limitation, any claim to “Defaulted Amounts” or “Additional Interest,” in respect of such Exchanged
Old Notes, in each case, arising under and defined in, the Old Notes Indenture. The Old Notes Trustee may rely on the immediately preceding sentence with the same force
and effect as if such representation or warranty were made directly to the Old Notes Trustee. The Old Notes Trustee shall be a third party beneficiary to this Exchange
Agreement to the extent provided in the immediately preceding sentence.

2.

[Reserved].

3. The Closing. The closing of the Exchange (the “Closing”) shall take place at the offices of Goodwin Procter LLP, 100 Northern Avenue, Boston, MA 02210, at 10:00 a.m.,

New York City time, on April 4, 2022 or at such other time and place as the Company may designate by notice to the Investor (the “Closing Date”).

4. Closing Mechanics.

a. The Depository Trust Company (“DTC”) will act as securities depositary for the New Notes.

b. At or prior to the times set forth in the Exchange Procedures set forth in Exhibit B hereto (the “Exchange Procedures”), the Investor, on behalf of itself and/or any
other Account, shall deliver and/or cause the Exchanging Holders to deliver the Exchanged Old Notes, by book entry transfer through the facilities of DTC, to The
Bank  Of  New  York  Mellon,  in  its  capacity  as  trustee  of  the  Old  Notes  (in  such  capacity,  the  “Old  Notes  Trustee”),  for  the  account/benefit  of  the  Company  for
cancellation as instructed in the Exchange Procedures.

c. On  the  Closing  Date,  subject  to  satisfaction  of  the  conditions  precedent  specified  in  Section 7  hereof,  and  the  prior  receipt  by  the  Old  Notes  Trustee  from  each

Exchanging Holder of the Exchanged Old Notes pursuant to clause (b) above:

(i) the Company and Parent shall execute and deliver the Indenture, dated as of the Closing Date, among the Company, Parent and the New Notes Trustee;

(ii) the Company shall execute, cause the New Notes Trustee to authenticate and cause to be delivered to the DTC account(s) specified by the Investor or the

relevant Account in Exhibit C hereto, the Exchanged New Notes; and

(iii)the Company shall deliver or cause to be delivered the Cash Consideration pursuant to the wire instructions specified by the Investor or the relevant Account in

Exhibit C hereto.

All questions as to the form of all documents and the validity and acceptance of the Old Notes and the New Notes will be determined by the Company, in its sole discretion,
which determination shall be final and binding.

5. Representations and Warranties and Covenants of the Company and Parent. Each of the Company and Parent, jointly and severally, represent and warrant to and covenant

with the Investor (and each Account, as applicable) that:

a. Organization. The Company is duly incorporated and is validly existing under the laws of the Cayman Islands. Parent is duly organized and is validly existing under

the laws of Ireland.

b. Due Authorization. This Exchange Agreement has been duly authorized, executed and delivered by each of the Company and Parent.

c. New Notes and the Guarantee. The New Notes have been duly authorized by the Company and, when duly executed by the Company in accordance with the terms
of the Indenture, assuming due authentication of the New Notes by the New Notes Trustee, upon delivery to the Purchasers in accordance with the terms of the
Exchange, will be validly issued and delivered and will constitute valid and binding obligations of the Company entitled to the benefits of the Indenture, enforceable
against the Company in accordance with their terms, except as such enforceability may be limited by bankruptcy, fraudulent conveyance, insolvency, reorganization,
moratorium,  and  other  laws  relating  to  or  affecting  creditors’  rights  generally  and  by  general  equitable  principles  (regardless  of  whether  such  enforceability  is
considered in a proceeding in equity or at law) (collectively, the “Enforceability Exceptions”). The register of the New Notes will at all times be maintained outside
of the Republic of Ireland. The Guarantee has been duly authorized by Parent and, when the New Notes are duly executed by the Company in accordance with the
terms of the Indenture, assuming due authentication of the New Notes by the New Notes Trustee, upon delivery to the Purchasers in accordance with the terms of
the  Exchange,  the  Guarantee  will  constitute  a  valid  and  binding  obligation  of  Parent,  enforceable  against  Parent  in  accordance  with  its  terms,  subject  to  the
Enforceability Exceptions. The maximum number of Underlying ADSs (including the Ordinary Shares represented thereby) initially issuable upon exchange of the
New Notes (assuming settlement solely in ADSs and taking into account the maximum make-whole adjustment under the Indenture) have been duly and validly
authorized  and  reserved  for  by  Parent  and,  when  issued  upon  exchange  of  the  New  Notes  in  accordance  with  the  terms  of  the  New  Notes  and  the  Deposit
Agreement, will be validly issued, fully paid and non-assessable, and the issuance of any Underlying ADSs (including the Ordinary Shares represented thereby) will
not be subject to any preemptive, participation, rights of first refusal or similar rights.

d.

Indenture. Each of the Company and Parent has all requisite organizational power and authority to perform its obligations under the Indenture. The Indenture has
been duly authorized by the Company and Parent, and will have been duly executed and delivered by the Company and Parent on or prior to the Closing. Assuming
due authorization, execution and delivery by the New Notes Trustee thereto, the Indenture, upon execution and delivery thereof by the Company and Parent, will
constitute the valid and binding agreement of the Company and Parent, enforceable against the Company and Parent in accordance with its terms, subject to the

itself and each Account, as applicable, that:

a. The Investor is a corporation, limited partnership, limited liability company or other entity, as the case may be, duly formed, validly existing and in good standing

under the laws of the jurisdiction of its formation.

b.

If the Investor is participating in the Exchange, the Investor has full power and authority to deliver, assign and transfer the Exchanged Old Notes in exchange for the
Exchange Consideration pursuant to this Exchange Agreement and to enter into this Exchange Agreement and perform all obligations required to be performed by
the Investor hereunder. If the Investor is executing this Exchange Agreement on behalf of an Account, (i) the Investor has all requisite authority to enter into this
Exchange Agreement on behalf of, and, bind, each Account to the terms of this Exchange Agreement and (ii) Exhibit A hereto is a true, correct and complete list of
(A) the name of each Exchanging Holder, and (B) the principal amount of each Exchanging Holder's Exchanged Old Notes.

c. Each Exchanging Holder participating in the Exchange is the current beneficial owner of the Exchanged Old Notes. When the Exchanged Old Notes are exchanged,
the Company will acquire good, marketable and unencumbered title thereto, free and clear of all liens, restrictions, charges, encumbrances, adverse claims, rights

d. Participation in the Exchange will not contravene (1) any law, rule or regulation binding on the Investor or any investment guideline or restriction applicable to the

Investor (or, if applicable, any Account) and (2) the charter or bylaws or similar organizational documents of the Investor (or, if applicable, any Account).

e. The  Investor  (or  applicable  Account)  is  a  resident  of  the  jurisdiction  set  forth  in  Exhibit C  and,  unless  otherwise  set  out  in  Exhibit A  hereto,  is  not  acquiring  the

acquisitions or sales, and Parent and the Company shall not have any responsibility therefor.

g. The Investor and each Account has received a copy of the Transaction Documents. The Investor acknowledges that: (1) no person has been authorized to give any
information  or  to  make  any  representation  concerning  the  Exchange,  Parent  or  any  of  its  subsidiaries,  including  the  Company,  other  than  as  contained  in  this
Exchange Agreement or the Transaction Documents or in the information given by Parent’s or the Company’s duly authorized officers and employees in connection
with the Investor’s examination of Parent and its subsidiaries and the terms of the Exchange; and (2) Parent and its subsidiaries do not take any responsibility for,

ACTIVE/115855038.2

h. The Investor and each Account understands and accepts that acquiring the New Notes in the Exchange involves risks. The Investor and each Account has such
knowledge, skill and experience in business, financial and investment matters that the Investor and each Account is capable of evaluating the merits and risks of the
Exchange  and  an  investment  in  the  New  Notes.  With  the  assistance  of  its  own  professional  advisors  (to  the  extent  the  Investor  and  each  Account  has  deemed
appropriate), the Investor and each Account has made its own legal, tax, accounting and financial evaluation of the merits and risks of an investment in the New
Notes and the consequences of the Exchange and this Exchange Agreement. The Investor and each Account has considered the suitability of the New Notes as an
investment in light of its own circumstances and financial condition, and the Investor and each Account is able to bear the risks associated with an investment in the
New Notes.

i.

j.

The Investor confirms that neither it nor any Account is relying on any communication (written or oral) of Parent, the Company or the Placement Agent or any of
their respective agents (including authorized officers and employees) or affiliates as investment advice or as a recommendation to participate in the Exchange and
receive  the  Exchange  Consideration  pursuant  to  the  terms  hereof.  It  is  understood  that  information  provided  in  the  Transaction  Documents,  or  by  Parent,  the
Company or the Placement Agent or any of their respective agents or affiliates, shall not be considered investment advice or a recommendation with respect to the
Exchange, and that none of Parent, the Company, the Placement Agent or any of their respective agents or affiliates is acting or has acted as an advisor to the
Investor  or  any  Account  in  deciding  whether  to  participate  in  the  Exchange.  The  Investor  and  each  Account  acknowledges  and  the  Investor  agrees  that  the
Placement Agent has not acted as a financial advisor or fiduciary to the Investor or any Account and that the Placement Agent, its affiliates and its or their directors,
officers, employees, representatives and controlling persons have no responsibility for making, and have not made, any independent investigation of the information
contained  herein  or  in  Parents  filings  with  the  Securities  and  Exchange  Commission  and  make  no  representation  or  warranty  to  the  Investor  or  any  Account,
express  or  implied,  with  respect  to  Parent,  the  Company,  the  Exchanged  Old  Notes  or  the  ADSs  or  the  accuracy,  completeness  or  adequacy  of  the  information
provided to the Investor or any Account or any other publicly available information, nor shall any of the foregoing persons be liable for any loss or damages of any
kind in connection with the Exchange.

The Investor confirms, for itself and for each Account, that none of Parent, the Company or the Placement Agent has (1) given any guarantee or representation as
to the potential success, return, effect or benefit (either legal, regulatory, tax, financial, accounting or otherwise) of an investment in the New Notes (except for the
Guarantee provided by Parent pursuant to the Indenture); or (2) made any representation to the Investor regarding the legality of an investment in the New Notes
under applicable investment guidelines, laws or regulations. In deciding to participate in the Exchange, neither the Investor nor any Account is relying on the advice
or  recommendations  of  Parent,  the  Company  or  the  Placement  Agent,  and  the  Investor  and  each  Account  has  made  its  own  independent  decision  that  the
investment in the New Notes is suitable and appropriate for the Investor or such Account.

k. The  Investor  and  each  Account  is  a  sophisticated  participant  in  the  transactions  contemplated  hereby  and  has  such  knowledge  and  experience  in  financial  and
business matters as to be capable of evaluating the merits and risks of an investment in the New Notes, is experienced in investing in capital markets and is able to
bear the economic risk of an investment in the New Notes. The Investor and each Account is familiar with the business and financial condition and operations of the
Company and its subsidiaries, including the Company, and has conducted its own investigation of Parent and its subsidiaries and the New Notes and has consulted
with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated
hereby. The Investor and each Account has had access to Parent’s filings with the Securities and Exchange Commission and such other information concerning
Parent and its subsidiaries and the New Notes as it deems necessary to enable it to make an informed investment decision concerning the Exchange. The Investor
and each Account has been offered the opportunity to ask questions of Parent, the Company and their respective representatives and has received answers thereto
as the Investor or such Account deems necessary to enable it to make its own informed investment decision concerning the Exchange and the New Notes. The

ACTIVE/115855038.2

6

Investor and each Account acknowledges and understands that at the time of the Closing, Parent and the Company may be in possession of material non-public
information not known to the Investor or any Account that may impact the value of the New Notes, the Exchanged Old Notes, and the ADSs (“Information”) that the
Company has not disclosed to the Investor or any Account. The Investor and each Account acknowledges that they have not relied upon the non-disclosure of any
such Information for purposes of making their decision to participate in the Exchange. The Investor and each Account understands, based on its experience, the
disadvantage to which the Investor and each Account is subject due to the disparity of information between Parent and the Company, on the one hand, and the
Investor and each Account, on the other hand. Notwithstanding this, the Investor and each Account has deemed it appropriate to participate in the Exchange. The
Investor agrees that Parent and the Company and their directors, officers, employees, agents, stockholders and affiliates shall have no liability to the Investor or any
Account or their respective beneficiaries whatsoever due to or in connection with Parent or the Company’s use or non-disclosure of the Information or otherwise as
a result of the Exchange, and the Investor hereby irrevocably waives any claim that it or any Account might have based on the failure of Parent or the Company to
disclose the Information.

l.

The Investor and each Account understands that no U.S. federal, state, local or non-U.S. agency has passed upon the merits or risks of an investment in the New
Notes or made any finding or determination concerning the fairness or advisability of such investment.

m. The Investor and each Account is a “qualified institutional buyer” as defined in Rule 144A under the Securities Act. The Investor, for itself and on behalf of each
Account, agrees to furnish any additional information reasonably requested by the Company or any of its affiliates to assure compliance with applicable U.S. federal
and state securities laws in connection with the Exchange.

n. The  Investor  and  each  Account  is  not  directly,  or  indirectly  through  one  or  more  intermediaries,  controlling  or  controlled  by,  or  under  direct  or  indirect  common
control with, Parent or the Company and is not, and has not been for the immediately preceding three months, an “affiliate” (within the meaning of Rule 144 under
the Securities Act) of Parent or the Company.

o. The  Investor  and  each  Account  is  acquiring  the  New  Notes  solely  for  the  Investor’s  or  such  Account’s  own  beneficial  account,  or  for  an  account  with  respect  to
which  the  Investor  or  such  Account  exercises  sole  investment  discretion,  for  investment  purposes,  and  not  with  a  view  to,  or  for  resale  in  connection  with,  any
distribution of the New Notes. The Investor and each Account understands that the offer and sale of the New Notes have not been registered under the Securities
Act or any state securities laws by reason of specific exemptions under the provisions thereof that depend in part upon the investment intent of the Investor or each
Account and the accuracy of the other representations made by the Investor and each Account in this Exchange Agreement.

p. The Investor and each Account understands that each of Parent and the Company is relying upon the representations and agreements contained in this Exchange
Agreement (and any supplemental information) for the purpose of determining whether the Investor’s and such Account’s participation in the Exchange meets the
requirements  for  the  exemptions  referenced  in  clause  6(o)  above.  In  addition,  the  Investor  and  each  Account  acknowledges  and  agrees  that  any  hedging
transactions engaged in by the Investor or such Account after the confidential information (as described in the confirmatory email received by the Investor from the
Placement Agent (the “Wall Cross Email”)) was made available to the Investor and prior to the Closing in connection with the issuance and sale of the New Notes
have been and will be conducted in compliance with the Securities Act and the rules and regulations promulgated thereunder.

q. The Investor and each Account acknowledges that the New Notes have not been registered under the Securities Act.

r. The Investor and each Account acknowledges that the terms of the Exchange have been mutually negotiated between the Investor (for itself and on behalf of each

Account), and

ACTIVE/115855038.2

7

the Company. The Investor was given a meaningful opportunity to negotiate the terms of the Exchange on behalf of itself and each Account.

s. The Investor and each Account acknowledges the Company intends to pay an advisory fee to the Placement Agent.

t. The  Investor  will,  for  itself  and  on  behalf  of  each  Account,  upon  request,  execute  and  deliver  any  additional  documents,  information  or  certifications  reasonably

requested by the Company, the Old Notes Trustee or the New Notes Trustee to complete the Exchange.

u. The  Investor  and  each  Account  understands  that,  unless  the  Investor  notifies  the  Company  in  writing  to  the  contrary  before  the  Closing,  each  of  the  Investor’s
representations and warranties contained in this Exchange Agreement will be deemed to have been reaffirmed and confirmed as of the Closing, taking into account
all information received by the Investor.

v. The participation in the Exchange by any Exchanging Holder was not conditioned by the Company on such Exchanging Holders’ exchange of a minimum principal

amount of Exchanged Old Notes.

w. The  Investor  acknowledges  that  it  and  each  Account  had  a  sufficient  amount  of  time  to  consider  whether  to  participate  in  the  Exchange  and  that  neither  the
Company  nor  the  Placement  Agent  has  placed  any  pressure  on  the  Investor  or  any  Account  to  respond  to  the  opportunity  to  participate  in  the  Exchange.  The
Investor acknowledges that neither it nor any Account did become aware of the Exchange through any form of general solicitation or advertising within the meaning
of Rule 502 under the Securities Act.

x. The operations of the Investor and each Account have been conducted in material compliance with the rules and regulations administered or conducted by the U.S.
Department of Treasury Office of Foreign Assets Control (“OFAC”) applicable to the Investor. The Investor has performed due diligence necessary to reasonably
determine that its (or, where applicable, any Account’s) beneficial owners are not named on the lists of denied parties or blocked persons administered by OFAC,
resident in or organized under the laws of a country that is the subject of comprehensive economic sanctions and embargoes administered or conducted by OFAC
(“Sanctions”), or otherwise the subject of Sanctions.

7. Conditions to Obligations of the Investor and the Company and Parent. The obligations of the Investor to deliver, or to cause the Accounts to deliver, the Exchanged Old
Notes, and of the Company to deliver the Exchange Consideration are subject to the satisfaction at or prior to the Closing of the condition precedent that the representations
and warranties of the Company and Parent on the one hand, and of the Investor on the other contained in Sections 5 and 6, respectively, shall be true and correct as of the
Closing in all material respects with the same effect as though such representations and warranties had been made as of the Closing.

8. Covenants and Acknowledgment of the Company and Parent. Parent hereby agrees to publicly disclose at or before 9:00 a.m., New York City time (the “Release Time”), on
the first business day after the date hereof, the Exchange as contemplated by this Exchange Agreement in a press release or a Current Report on Form 8-K filed with the
Securities and Exchange Commission. Parent hereby acknowledges and agrees that, as of the Release Time, Parent will disclose all confidential information to the extent
Parent believes such confidential information constitutes material non-public information, if any, with respect to the Exchange or that was otherwise communicated by the
Company and/or Parent to the Investor or any Account in connection with the Exchange. For the avoidance of doubt, each of Parent and the Company may be aware of
material non-public information regarding Parent and/or the Company at the time of Closing that has not been communicated to the Investor or any Account. Parent will,
within  two  (2)  business  days  after  the  Closing,  file  a  Current  Report  on  Form  8-K  publicly  disclosing  the  closing  of  the  Exchange  as  contemplated  by  this  Exchange
Agreement.

10. Waiver, Amendment. Neither this Exchange Agreement nor any provisions hereof shall be modified, changed, discharged or terminated except by an instrument in writing,

signed by the party against whom any waiver, change, discharge or termination is sought.

11. Assignability.  Neither  this  Exchange  Agreement  nor  any  right,  remedy,  obligation  or  liability  arising  hereunder  or  by  reason  hereof  shall  be  assignable  by  Parent,  the

Company or the Investor without the prior written consent of the other parties.

12. Reserved.

13. Waiver of Jury Trial. EACH OF PARENT, THE COMPANY AND THE INVESTOR (FOR ITSELF AND, IF APPLICABLE, ON BEHALF OF EACH ACCOUNT) IRREVOCABLY

proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

16. Venue. Each of Parent, the Company and the Investor (for itself and, if applicable, on behalf of each Account) irrevocably and unconditionally waives, to the fullest extent it
may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this
Exchange  Agreement  in  any  court  referred  to  in  Section  15.  Each  of  Parent,  the  Company  and  the  Investor  (for  itself  and,  if  applicable,  on  behalf  of  each  Account)
irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.
