Proprietary Products

We have developed and now commercialize products designed to help address the unmet needs of people living with opioid dependence, alcohol dependence, schizophrenia and bipolar I disorder. See the “Patents and Proprietary Rights” section in “Item 1—Business” in this Annual Report for information with respect to the IP protection for our proprietary products.

ARISTADA

ARISTADA (aripiprazole lauroxil) is an extended-release intramuscular injectable suspension approved in the U.S. for the treatment of schizophrenia. ARISTADA utilizes our proprietary LinkeRx technology. ARISTADA is a prodrug; once in the body, ARISTADA is likely converted by enzyme-mediated hydrolysis to N-hydroxymethyl aripiprazole, which is then hydrolyzed to aripiprazole. ARISTADA is available in four dose strengths with once-monthly dosing options (441 mg, 662 mg and 882 mg), a six-week dosing option (882 mg) and a two-month dosing option (1064 mg). ARISTADA is packaged in a ready-to-use, pre-filled syringe product format. We developed ARISTADA and exclusively manufacture and commercialize it in the U.S.

ARISTADA INITIO

ARISTADA INITIO (aripiprazole lauroxil) leverages our proprietary LinkeRx and NanoCrystal technologies and provides an extended-release formulation of aripiprazole lauroxil in a smaller particle size compared to ARISTADA, thereby enabling faster dissolution and more rapid achievement of relevant levels of aripiprazole in the body. ARISTADA INITIO, combined with a single 30 mg dose of oral aripiprazole, is indicated for the initiation of ARISTADA when used for the treatment of schizophrenia in adults. The first ARISTADA dose may be administered on the same day as the ARISTADA INITIO regimen or up to 10 days thereafter. We developed ARISTADA INITIO and exclusively manufacture and commercialize it in the U.S.

What is schizophrenia?

Schizophrenia is a serious brain disorder marked by positive symptoms (hallucinations and delusions, disorganized speech and thoughts, and agitated or repeated movements) and negative symptoms (depression, blunted emotions and social withdrawal). Schizophrenia affects approximately 1.1% of the U.S. population.

LYBALVI

LYBALVI (olanzapine and samidorphan) is a once-daily, oral atypical antipsychotic drug approved in the U.S. for the treatment of adults with schizophrenia and for the treatment of adults with bipolar I disorder, as a maintenance monotherapy or for the acute treatment of manic or mixed episodes, as monotherapy or an adjunct to lithium or valproate. LYBALVI is composed of olanzapine, an established antipsychotic agent, co-formulated with samidorphan, a new chemical entity, in a single bilayer tablet. LYBALVI was launched commercially in October 2021 and is available in fixed dosage strengths composed of 10 mg of samidorphan and 5 mg, 10 mg, 15 mg or 20 mg of olanzapine. We developed LYBALVI and exclusively manufacture and commercialize it in the U.S.

What is bipolar I disorder?

Bipolar I disorder is a brain disorder that is marked by extreme changes in a person’s mood, energy and ability to function. Individuals with this brain disorder may experience debilitating changes in mood from extreme highs (mania) to extreme lows (depression). Bipolar I disorder is characterized by the occurrence of at least one manic episode, with or without the occurrence of a major depressive episode, and affects approximately 1% of the American adult population in any given year.

VIVITROL

VIVITROL (naltrexone for extended-release injectable suspension) is a once-monthly, non-narcotic, injectable medication approved in the U.S., Russia and certain countries of the Commonwealth of Independent States for the treatment of alcohol dependence and for the prevention of relapse to opioid dependence, following opioid detoxification. VIVITROL uses our polymer-based microsphere injectable extended-release technology to deliver and maintain therapeutic medication levels in the body through one intramuscular injection every four weeks. We developed and exclusively manufacture VIVITROL and we commercialize it in the U.S.

For a discussion of legal proceedings related to VIVITROL, see Note 19, Commitments and Contingent Liabilities in the “Notes to Consolidated Financial Statements” in this Annual Report, and for information about risks relating to such legal proceedings, see “Item 1A—Risk Factors” in this Annual Report and specifically the sections entitled “Patent and other IP protection for our products is key to our business and our competitive position but is uncertain,” “Uncertainty over IP in the biopharmaceutical industry has been the source of litigation, which is inherently costly and unpredictable, could significantly delay or prevent approval or negatively impact commercialization of our products, and could adversely affect our business” and “Litigation or arbitration filed against Alkermes, including securities litigation, or actions (such as citizens petitions) filed against regulatory agencies in respect of our

products, may result in financial losses, harm our reputation, divert management resources, negatively impact the approval of our products, or otherwise negatively impact our business.”

What are opioid dependence and alcohol dependence?

Opioid dependence is a serious and chronic brain disease characterized by compulsive, prolonged self-administration of opioid substances that are not used for a medical purpose. According to the 2020 U.S. National Survey on Drug Use and Health, an estimated 2.6 million people aged 18 or older in the U.S. had an opioid use disorder in the past year. Alcohol dependence is a serious and chronic brain disease characterized by cravings for alcohol, loss of control over drinking, withdrawal symptoms and an increased tolerance for alcohol. According to the 2020 U.S. National Survey on Drug Use and Health, an estimated 27.8 million people aged 18 or older in the U.S. had an alcohol use disorder in the past year. Adherence to medication is particularly challenging with these patient populations.

In 2013, with the publication of the Diagnostic Statistical Manual (“DSM”) 5, the DSM IV diagnoses of substance use disorders as either dependence or abuse (i.e., opioid dependence or alcohol dependence), which reflects the approved indications of VIVITROL, were subsumed under a new diagnostic category of “substance use disorders” (i.e., opioid use disorder or alcohol use disorder) with three categories of disorder severity—mild, moderate or severe.

Licensed Products and Products Using Our Proprietary Technologies

We have licensed products to third parties for commercialization and have licensed our proprietary technologies to third parties to enable them to develop, commercialize and/or manufacture products. See the “Proprietary Technology Platforms and “Patents and Proprietary Rights” sections in “Item 1—Business” in this Annual Report for information with respect to our proprietary technologies and the IP protection for these products. We receive royalties and/or manufacturing and other revenues from the commercialization of these products under our collaborative arrangements with these third parties.

What is multiple sclerosis?

Multiple sclerosis, or MS, is an unpredictable, often disabling disease of the central nervous system (“CNS”), which interrupts the flow of information within the brain, and between the brain and body. MS symptoms can vary over time and from person to person. Symptoms may include extreme fatigue, impaired vision, problems with balance and walking, numbness or pain and other sensory changes, bladder and bowel symptoms, tremors, problems with memory and concentration and mood changes, among others. Approximately 2.5 million people worldwide have MS, and most are diagnosed between the ages of 15 and 50.

Key Development Program

Our R&D is focused on the development of innovative medicines in the fields of neuroscience and oncology that are designed to address unmet patient needs. As part of our ongoing R&D efforts, we have devoted, and will continue to devote, significant resources to conducting preclinical work and clinical studies to advance the development of new pharmaceutical products. The discussion below highlights our current key development program. Drug development involves a high degree of risk and investment, and the status, timing and scope of our development programs are subject to change. Important factors that could adversely affect our drug development efforts are discussed in “Item 1A—Risk Factors” in this Annual Report. See the “Patents and Proprietary Rights” section in “Item 1—Business” in this Annual Report for information with respect to the IP protection for our key development program.

nemvaleukin alfa

Nemvaleukin alfa (“nemvaleukin”) is an investigational, novel, engineered fusion protein comprised of modified interleukin-2 (“IL-2”) and the high affinity IL-2 alpha receptor chain, designed to preferentially expand tumor-killing immune cells while avoiding

11

Table of Contents

the activation of immunosuppressive cells by selectively binding to the intermediate-affinity IL-2 receptor complex. The selectivity of nemvaleukin is designed to leverage the proven anti-tumor effects of existing IL-2 therapy while mitigating certain limitations.

ARTISTRY is our clinical development program evaluating nemvaleukin as a potential immunotherapy for cancer. The ARTISTRY program is comprised of multiple clinical trials evaluating intravenous (“IV”) and subcutaneous (“SC”) dosing of nemvaleukin, both as a monotherapy and in combination with the anti-PD-1 therapy KEYTRUDA (pembrolizumab) in patients with advanced solid tumors. ARTISTRY-1 (evaluating IV nemvaleukin) and ARTISTRY-2 (evaluating SC nemvaleukin) are ongoing phase 1/2 studies evaluating the safety, tolerability, efficacy and pharmacokinetic and pharmacodynamic effects of nemvaleukin in patients with refractory advanced solid tumors, in both monotherapy and combination settings. ARTISTRY-3 is an ongoing phase 2 study evaluating the efficacy, safety and tolerability of less frequent  dosing of IV nemvaleukin and pharmacokinetic and pharmacodynamic effects of IV nemvaleukin in the tumor microenvironment as a monotherapy and in combination with pembrolizumab in a variety of advanced solid tumors. ARTISTRY-6 is an ongoing phase 2 study evaluating the anti-tumor activity, safety and tolerability of IV nemvaleukin monotherapy in patients with mucosal melanoma and SC nemvaleukin monotherapy in patients with advanced cutaneous melanoma. ARTISTRY-7 is an ongoing phase 3 study evaluating the efficacy, safety and tolerability of IV nemvaleukin as monotherapy and in combination with pembrolizumab compared to investigator’s choice chemotherapy in patients with platinum-resistant ovarian cancer.

In March 2021 and August 2021, we announced that the FDA granted Orphan Drug Designation and Fast Track designation, respectively, to nemvaleukin for the treatment of mucosal melanoma. In October 2021, the FDA granted Fast Track designation to nemvaleukin in combination with pembrolizumab for the treatment of platinum-resistant ovarian cancer.

Collaborative Arrangements

We have entered into several collaborative arrangements to develop and commercialize products and, in connection with such arrangements, to access technological, financial, marketing, manufacturing and other resources.

Janssen

INVEGA SUSTENNA/XEPLION, INVEGA TRINZA/TREVICTA and INVEGA HAFYERA/BYANNLI

In November 2021, we received notice of partial termination in the U.S. of our license agreement with Janssen related to INVEGA SUSTENNA, INVEGA TRINZA, and INVEGA HAFYERA. The basis for this termination is Janssen’s assertion that it does not utilize our NanoCrystal technology licensed under the license agreement. We strongly disagree with Janssen’s position and are prepared to pursue all options at our disposal to enforce our contractual rights and address any unauthorized use of our intellectual property. For information about risks relating to this notice of partial termination and our collaborative arrangements more broadly, see “Item 1A—Risk Factors” in this Annual Report and specifically those sections entitled “We rely heavily on our licensees in the commercialization and continued development of products from which we receive revenue and, if our licensees are not effective, or if disputes arise in respect of our contractual arrangements, our revenues could be materially adversely affected.”

Under our license agreement with Janssen Pharmaceutica N.V., we granted Janssen a worldwide exclusive license under our NanoCrystal technology to develop, commercialize and manufacture injectable pharmaceutical products containing paliperidone palmitate, which include the long-acting INVEGA products.

Under this license agreement, we received milestone payments from Janssen upon the achievement of certain development goals; there are no further milestones to be earned under this agreement. The agreement also provides for tiered royalty payments between 3.5% and 9% of net sales of products subject to the agreement in each country where the license is in effect, with the exact royalty percentage determined based on aggregate worldwide net sales. The tiered royalty payments consist of a patent royalty and a know‑how royalty, both of which are determined on a country‑by‑country basis. The patent royalty, which equals 1.5% of net sales, is payable in each country until the expiration of the last of the royalty-bearing patents with valid claims applicable to the product in such country. The know‑how royalty is a tiered royalty of 3.5% on calendar year net sales up to $250 million, 5.5% on calendar year net sales of between $250 million and $500 million and 7.5% on calendar year net sales exceeding $500 million. The know‑how royalty rate resets to 3.5% at the beginning of each calendar year and is payable until 15 years from the first commercial sale of a product in each individual country. These royalty payments may be reduced in any country based on patent litigation or on competing products achieving certain minimum sales thresholds. The license agreement, unless earlier terminated, terminates upon the expiration of the last of the patents subject to the agreement. After expiration, Janssen retains a non‑exclusive, royalty‑free license to develop, manufacture and commercialize the products subject to certain surviving obligations.

Janssen may terminate the license agreement in whole or in part upon three months’ notice to us. We and Janssen have the right to terminate the agreement upon a material breach of the other party, which is not cured within a certain time period, or upon the other party’s bankruptcy or insolvency.

RISPERDAL CONSTA

Under a product development agreement, we collaborated with Janssen on the development of RISPERDAL CONSTA. Under the development agreement, Janssen provided funding to us for the development of RISPERDAL CONSTA, and Janssen is responsible for securing all necessary regulatory approvals for the product.

Under two license agreements, we granted Janssen and an affiliate of Janssen exclusive worldwide licenses to use and sell RISPERDAL CONSTA. Under our license agreements with Janssen, we receive royalty payments equal to 2.5% of Janssen’s end-market net sales of RISPERDAL CONSTA in each country where the license is in effect based on the quarter when the product is sold by Janssen. This royalty may be reduced in any country based on lack of patent coverage and significant competition from generic versions of the product. Janssen can terminate the license agreements upon 30 days’ prior written notice to us. Either party may terminate the license agreements by written notice following a breach which continues for 90 days after the delivery of written notice thereof or upon the other party’s insolvency. The licenses granted to Janssen expire on a country‑by‑country basis upon the later of (i) the expiration of the last patent claiming the product in such country or (ii) 15 years after the date of the first commercial sale of the product in such country, provided that in no event will the license granted to Janssen expire later than the twentieth anniversary of the first commercial sale of the product in each such country, with the exception of Canada, France, Germany, Italy, Japan, Spain and the United Kingdom, in each case, where the fifteen‑year minimum shall pertain regardless. After expiration, Janssen retains a non‑exclusive, royalty‑free license to manufacture, use and sell RISPERDAL CONSTA.

We exclusively manufacture RISPERDAL CONSTA for commercial sale. Under our manufacturing and supply agreement with Janssen, we receive manufacturing revenue based on a percentage of Janssen’s net unit sales price for RISPERDAL CONSTA for the applicable calendar year. This percentage is determined based on Janssen’s unit demand for such calendar year and varies based on the volume of units shipped, with a minimum manufacturing fee of 7.5%. Either party may terminate the manufacturing and supply agreement upon a material breach by the other party, which is not resolved within 60 days after receipt of a written notice specifying the material breach or upon written notice in the event of the other party’s insolvency or bankruptcy. Janssen may terminate the agreement upon six months’ written notice to us. In the event that Janssen terminates the manufacturing and supply agreement without terminating the license agreements, the royalty rate payable to us on Janssen’s net sales of RISPERDAL CONSTA would increase from 2.5% to 5.0%.

Revenues from our collaborative arrangements with Janssen accounted for approximately 30%, 33% and 28% of our consolidated revenues for the years ended December 31, 2021, 2020 and 2019, respectively.

Under a license and collaboration agreement with Biogen, which we entered into in November 2017 and amended in October 2018, January 2019 and October 2019, we granted Biogen a worldwide, exclusive, sublicensable license to develop, manufacture and commercialize VUMERITY and other products covered by patents licensed to Biogen under that agreement.

Under this license and collaboration agreement, we received an upfront cash payment and milestone payments upon the achievement of certain milestones, including FDA approval of the NDA for VUMERITY in October 2019, and amendment of the license and collaboration agreement in October 2019. We are also eligible to receive additional payments upon achievement of certain milestones, including milestones relating to the first two products, other than VUMERITY, covered by patents licensed to Biogen under the license and collaboration agreement.

In addition, we receive a 15% royalty on worldwide net sales of VUMERITY, subject to, under certain circumstances, minimum annual payments for the first five years following FDA approval of VUMERITY. We are also entitled to receive royalties on net sales of products other than VUMERITY covered by patents licensed to Biogen under the license and collaboration agreement, at tiered royalty rates calculated as percentages of net sales ranging from high-single digits to sub-teen double digits. All royalties are payable on a product-by-product and country-by-country basis until the later of (i) the last-to-expire patent right covering the applicable product in the applicable country and (ii) a specified period of time from the first commercial sale of the applicable product in the applicable country. Royalties for all products and the minimum annual payments for VUMERITY are subject to customary reductions, as set forth in the license and collaboration agreement.

Except in limited circumstances, we were responsible for the development of VUMERITY until it was approved by the FDA. Following FDA approval of VUMERITY and except for the manufacturing responsibilities discussed below, Biogen is now responsible for all development and commercialization activities for VUMERITY and all other products covered by the patents that we licensed to Biogen.

Under the license and collaboration agreement, Biogen appointed us as the toll manufacturer of clinical and commercial supplies of VUMERITY, subject to Biogen’s right to manufacture or have manufactured commercial supplies as a back-up manufacturer and

13

Table of Contents

subject to good faith agreement by the parties on the terms of such manufacturing arrangements. In October 2019, we entered into a commercial supply agreement with Biogen for the commercial supply of VUMERITY, an amendment to such commercial supply agreement and an amendment to the November 2017 license and collaboration agreement with Biogen. Biogen has elected to initiate a technology transfer and, following a transition period, assume responsibility for the manufacture (itself or through a designee) of clinical supplies of VUMERITY and up to 100% of commercial supplies of VUMERITY in exchange for an increase in the royalty rate to be paid by Biogen to us on net sales of that portion of product that is manufactured by Biogen or its designee.

Unless earlier terminated, the license and collaboration agreement will remain in effect until the expiry of all royalty obligations. Biogen has the right to terminate the license and collaboration agreement at will, on a product-by-product basis or in its entirety upon 180 days’ prior notice to us. Either party has the right to terminate the license and collaboration agreement following any governmental prohibition of the transactions effected by the agreement, or in connection with an insolvency event involving the other party. Upon termination of the license and collaboration agreement by either party, then, at our request, the VUMERITY program will revert to us.

Revenues from Biogen related to this license and collaboration agreement accounted for approximately 7%, 2% and 17% of our consolidated revenues for the years ended December 31, 2021, 2020 and 2019, respectively.

Proprietary Technology Platforms

We have used our proprietary technology platforms, which include technologies owned and exclusively licensed to us, to establish drug development, clinical development and regulatory expertise and in the development of our products.

Injectable Extended‑Release Microsphere Technology

Our injectable extended‑release microsphere technology allows us to encapsulate small‑molecule pharmaceuticals, peptides and proteins in microspheres made of common medical polymers. The technology is designed to enable novel formulations of pharmaceuticals by providing controlled, extended release of drugs over time. Drug release from the microsphere is controlled by diffusion of the drug through the microsphere and by biodegradation of the polymer. These processes can be modulated through a number of formulation and fabrication variables, including drug substance and microsphere particle sizing and choice of polymers and excipients.

LinkeRx Technology

Our long‑acting LinkeRx technology platform is designed to enable the creation of extended‑release injectable versions of antipsychotic therapies and may also be useful in other disease areas in which extended duration of action may provide therapeutic benefits. The technology uses proprietary linker‑tail chemistry to create new molecular entities derived from known agents.

NanoCrystal Technology

Our NanoCrystal technology is applicable to poorly water‑soluble compounds and involves formulating and stabilizing drugs into particles that are nanometers in size. A drug in NanoCrystal form can be incorporated into a range of common dosage forms, including tablets, capsules, inhalation devices and sterile forms for injection, with the potential for enhanced oral bioavailability, increased therapeutic effectiveness, reduced/eliminated fed/fasted variability and sustained duration of intravenous/intramuscular release.

Oral Controlled Release Technology

Our oral controlled release (“OCR”) technologies are used to formulate, develop and manufacture oral dosage forms of pharmaceutical products with varied drug release profiles.

Manufacturing and Product Supply

We own and occupy an R&D and manufacturing facility in Athlone, Ireland and a manufacturing facility in Wilmington, Ohio. We either purchase active pharmaceutical ingredient (“API”) from third parties or receive it from our third‑party licensees to formulate products using our technologies. The manufacture of our products for clinical trials and commercial use is subject to Current Good Manufacturing Practices (“cGMP”) regulations and other regulations. Our manufacturing and development capabilities include formulation through process development, scale‑up and full‑scale commercial manufacturing and specialized capabilities for the development and manufacturing of controlled substances.

Although some materials and related services for our products are currently only available from a single source or a limited number of qualified sources, we attempt to acquire an adequate inventory of such materials, establish alternative sources for such

14

Table of Contents

materials and related services and/or negotiate long‑term supply arrangements. However, we cannot be certain that we will continue to be able to obtain long‑term supplies of our manufacturing materials or long-term provision of related services.

Our supply chain is growing with an expanding external network of third‑party service providers involved in the manufacture of our products who are subject to inspection by the FDA or comparable agencies in other jurisdictions. Any delay, interruption or other issues that arise in the acquisition of API, raw materials, or components, or in the manufacture, fill‑finish, packaging, or storage of our marketed or development products, including as a result of a failure of our facilities or the facilities or operations of third parties to pass any regulatory agency inspection, could significantly impair our ability to sell our products or advance our development efforts, as the case may be. For information about risks relating to the manufacture of our marketed products and product candidates, see “Item 1A—Risk Factors” in this Annual Report and specifically those sections entitled “We rely on third parties to provide services in connection with the manufacture and distribution of the products we manufacture” and “We are subject to risks related to the manufacture of our products.”

Marketed Products

We manufacture ARISTADA, ARISTADA INITIO, LYBALVI, VIVITROL and microspheres for RISPERDAL CONSTA at our Wilmington, Ohio facility. We outsource our packaging operations for ARISTADA, ARISTADA INITIO, LYBALVI and VIVITROL to third‑party contractors. Janssen is responsible for packaging operations for RISPERDAL CONSTA. Our Wilmington, Ohio facility has been inspected by U.S., European (including the UK Medicines and Healthcare products Regulatory Agency), Chinese, Japanese, Brazilian, Turkish, Russian and Saudi Arabian regulatory authorities for compliance with required cGMP standards for continued commercial manufacturing.

We manufacture several products in our Athlone, Ireland facility that are marketed by third parties, including AMPYRA, FAMPYRA and VUMERITY. This facility has been inspected by U.S., Irish, Brazilian, Turkish, Saudi Arabian, Korean, Belarusian, Russian and Chinese regulatory authorities for compliance with required cGMP standards for continued commercial manufacturing.

For more information about our manufacturing facilities, see “Item 2—Properties” in this Annual Report.

Clinical Products

We have established, and are operating, facilities with the capability to manufacture clinical supplies of injectable extended‑release products and solid dosage form products at our Wilmington, Ohio facility and solid dosage form products at our Athlone, Ireland facility. We have also contracted with third‑party manufacturers to formulate certain products for clinical use. We require that our contract manufacturers adhere to cGMP in the manufacture of products for clinical use.

Research & Development

We devote significant resources to R&D programs. We focus our R&D efforts on developing novel therapeutics in areas of high unmet medical need. Our R&D efforts include, but are not limited to, areas such as pharmaceutical formulation, analytical chemistry, process development, engineering, scale‑up and drug optimization/delivery. Please see “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this Annual Report for additional information relating to our R&D expenditures.

Permits and Regulatory Approvals

We hold various licenses in respect of our manufacturing activities conducted in Wilmington, Ohio and Athlone, Ireland. The primary licenses held in this regard are FDA Registrations of Drug Establishment and Drug Enforcement Administration of the U.S. Department of Justice (“DEA”). We also hold a Manufacturers Authorization (No. M1067), an Investigational Medicinal Products Manufacturers Authorization (No. IMP074) and Certificates of Good Manufacturing Practice Compliance of a Manufacturer (Ref. 2014/7828/IMP074 and 2014/7828/M1067) from the Health Products Regulatory Authority in Ireland (“HPRA”) in respect of our Athlone, Ireland facility, and a number of Controlled Substance Licenses granted by HPRA. Due to certain U.S. state law requirements, we also hold state licenses to cover distribution activities conducted in certain states and not in respect of any manufacturing activities conducted in those states.

We do not generally act as the marketing authorization holder for products incorporating our drug delivery technologies that have been developed on behalf of a licensee of such technologies. In such cases, our licensee usually holds the relevant marketing authorization from the FDA or other relevant regulatory authority, and we would support this authorization by furnishing a copy of the product’s Drug Master File, or chemistry, manufacturing and controls data, to the relevant regulator. We generally update this information annually with the relevant regulator. In other cases where we have developed proprietary products, such as VIVITROL, ARISTADA, ARISTADA INITIO and LYBALVI, we hold the marketing authorization and related regulatory documentation ourselves.

Marketing, Sales and Distribution

We are responsible for the marketing of VIVITROL, ARISTADA, ARISTADA INITIO, and LYBALVI in the U.S. We focus our sales and marketing efforts on physicians in private practice and in public treatment systems. We believe that we use customary pharmaceutical company practices to market our products, including through advertisements, professional symposia, selling initiatives and other methods, and to educate individual physicians, nurses, social workers, counselors and other stakeholders involved in the treatment of opioid dependence, alcohol dependence, schizophrenia and bipolar I disorder. We provide, and contract with third‑party vendors to provide, customer services and other related programs for our products, such as product‑specific websites, insurance research services and order, delivery and fulfillment services.

Our sales force for VIVITROL in the U.S. consists of approximately 115 individuals. VIVITROL is primarily sold to pharmaceutical wholesalers, pharmacies, specialty distributors and treatment providers. Product sales of VIVITROL during the year ended December 31, 2021 to Cardinal Health, McKesson Corporation and AmerisourceBergen Corporation (“AmerisourceBergen”) represented approximately 23%, 22% and 15%, respectively, of total VIVITROL gross sales.

Our sales force for ARISTADA, ARISTADA INITIO and LYBALVI in the U.S. consists of approximately 310 individuals. ARISTADA, ARISTADA INITIO and LYBALVI are primarily sold to pharmaceutical wholesalers. Product sales of ARISTADA and ARISTADA INITIO during the year ended December 31, 2021 to Cardinal Health, McKesson Corporation and AmerisourceBergen represented approximately 47%, 23% and 23%, respectively, of total ARISTADA and ARISTADA INITIO gross sales. Product sales of LYBALVI during the year ended December 31, 2021 to Cardinal Health, McKesson Corporation and AmerisourceBergen represented approximately 36%, 30% and 27%, respectively, of total LYBALVI gross sales.

ICS, a division of AmerisourceBergen, provides warehousing, shipping and administrative services for VIVITROL, ARISTADA, ARISTADA INITIO and LYBALVI.

Under our license agreements with Janssen, Biogen and other licensees and sublicensees, the licensees and sublicensees are typically responsible for the commercialization of any products developed under their respective agreements if and when regulatory approval is obtained.

Competition

We face intense competition in the development, manufacture, marketing and commercialization of our products from many and varied sources, such as research institutions and biopharmaceutical companies, including other companies with similar technologies. Some of these competitors are also our licensees, who control the commercialization of products from which we receive manufacturing and royalty revenues. These competitors are working to develop and market other products, systems, and other methods of preventing or reducing disease, and new small‑molecule and other classes of drugs.

The biopharmaceutical industry is characterized by intensive research, development and commercialization efforts and rapid and significant technological change. In many cases, there are already products on the market that may be in direct competition with our commercial products or products in development. In addition, there are many companies developing products for use in similar indications or with similar technologies to ours with whom we and our licensees compete, many of whom are larger and have significantly greater financial and other resources than we do. Other smaller or earlier stage companies may also prove to be significant competitors, particularly through focused development programs and collaborative arrangements with large, established companies. Some of the products being developed by our competitors are being designed to work differently than our products and may turn out to be safer or more effective than our products, which may render our products or technology platforms obsolete or noncompetitive. With respect to our products, we believe that our ability to successfully compete will depend on, among other things, the existence of competing or alternative products in the marketplace, including generic competition, and the relative price of those products; the efficacy, safety and reliability of our products compared to competing or alternative products; product acceptance by, and preferences of, physicians, other healthcare providers and patients; our ability to comply with applicable laws, regulations and regulatory requirements with respect to the commercialization of our products, including any changes or increases to regulatory restrictions; protection of our proprietary rights relating to our products; our ability to obtain reimbursement for our products; our ability to complete clinical development and obtain regulatory approvals for our products, and the timing and scope of any such regulatory approvals; our ability to successfully manufacture and provide a reliable supply of commercial quantities of a product to the market; and our ability to recruit, retain and develop skilled employees.

With respect to our proprietary injectable product platform, we are aware that there are other companies developing extended-release delivery systems for pharmaceutical products, including but not limited to, Teva Pharmaceuticals Industries Ltd.’s development of a risperidone extended-release injectable suspension for subcutaneous use and a once every two weeks injectable microsphere formulation, each for the treatment of schizophrenia, and Teva Pharmaceuticals USA, Inc.’s Abbreviated New Drug Application (“ANDA”) seeking approval to commercialize a generic version of VIVITROL (naltrexone for extended-release injectable suspension).

Table of Contents

In the treatment of schizophrenia, ARISTADA, the long-acting INVEGA products and RISPERDAL CONSTA compete with each other and a number of other injectable products, including ZYPREXA RELPREVV ((olanzapine) For Extended Release Injectable Suspension), which is marketed and sold by Lilly; ABILIFY MAINTENA (aripiprazole for extended release injectable suspension), a once-monthly injectable formulation of ABILIFY (aripiprazole) developed by Otsuka Pharm. Co.; PERSERIS (risperidone for extended release injectable suspension), a once-monthly formulation of risperidone marketed by Indivior plc; and generic versions of branded injectable products.

In the treatment of schizophrenia, LYBALVI competes with other oral antipsychotic products, including CAPLYTA (lumateperone) developed and marketed by Intra-Cellular Therapies, Inc.; LATUDA, which is marketed and sold by Sunovion Pharmaceuticals Inc.; REXULTI, which is co-marketed by Otsuka Pharm Co. and H. Lundbeck A/S plc; VRAYLAR, which is marketed and sold by Abbvie Inc.; other oral compounds currently on the market; and generic versions of branded oral products.

In the treatment of bipolar disorder, LYBALVI and RISPERDAL CONSTA compete with antipsychotics such as oral aripiprazole; REXULTI; LATUDA; VRAYLAR; ABILIFY MAINTENA; CAPLYTA; risperidone; quetiapine; olanzapine; ziprasidone and clozapine.

In the treatment of alcohol dependence, VIVITROL competes with generic acamprosate calcium (also known as CAMPRAL) and generic disulfiram (also known as ANTABUSE) as well as currently marketed drugs, including generic drugs, also formulated from naltrexone. Other pharmaceutical companies are developing products that have shown some promise in treating alcohol dependence that, if approved by the FDA, would compete with VIVITROL.

In the treatment of opioid dependence, VIVITROL competes with SUBOXONE (buprenorphine HCl/naloxone HCl dehydrate sublingual tablets), SUBOXONE (buprenorphine/naloxone) Sublingual Film, SUBUTEX (buprenorphine HCl sublingual tablets) and SUBLOCADE (once-monthly buprenorphine extended-release injection), each of which is marketed and sold by Indivior plc; BUNAVAIL buccal film (buprenorphine and naloxone) marketed by BioDelivery Sciences; and ZUBSOLV (buprenorphine and naloxone) marketed by Orexo US, Inc. VIVITROL also competes with methadone, oral naltrexone and generic versions of SUBUTEX and SUBOXONE sublingual tablets. Other pharmaceutical companies are developing products that have shown promise in treating opioid dependence that, if approved by the FDA, would compete with VIVITROL.

In the treatment of MS, VUMERITY competes with AVONEX, TYSABRI, TECFIDERA, and PLEGRIDY from Biogen; OCREVUS from Genentech; BETASERON from Bayer HealthCare Pharmaceuticals; COPAXONE from Teva Pharmaceutical Industries Ltd.; REBIF and MAVENCLAD from EMD Serono, Inc.; GILENYA, EXTAVIA and MAYZENT from Novartis AG; AUBAGIO and LEMTRADA from Sanofi-Aventis; ZEPOSIA from Bristol-Myers Squibb Company; and PONVORY from Janssen.

With respect to our NanoCrystal technology, we are aware that other technology approaches similarly address poorly water‑soluble drugs. These approaches include nanoparticles, cyclodextrins, lipid‑based self‑emulsifying drug delivery systems, dendrimers and micelles, among others, any of which could limit the potential success and growth prospects of products incorporating our NanoCrystal technology. In addition, there are many competing technologies to our OCR technology, some of which are owned by large pharmaceutical companies with drug delivery divisions and other, smaller drug‑delivery‑specific companies.

Patents and Proprietary Rights

Our success depends, in part, on our ability to obtain and maintain patent protection for our products, including those marketed and sold by our licensees, to maintain trade secret protection and to operate without infringing upon the proprietary rights of others. We have a proprietary portfolio of patent rights and exclusive licenses to patents and patent applications, which includes numerous patents in the U.S. and in other countries directed to compositions of matter, methods of treatment and formulations, as well as processes of preparation. In the future, we plan to file additional patent applications in the U.S. and in other countries directed to new or improved products and processes, and we intend to continue to vigorously defend our patent positions. In addition, our licensees may own additional patents that cover those products owned by such licensees that incorporate our proprietary technologies and for which we receive royalties.

ARISTADA and ARISTADA INITIO

We have several U.S. patents and patent applications, and a number of corresponding non-U.S. counterparts, that cover ARISTADA and/or ARISTADA INITIO. Our principal U.S. patents for ARISTADA and/or ARISTADA INITIO and their expiration dates are as follows:

VIVITROL and RISPERDAL CONSTA

We have a number of patents and pending patent applications covering our microsphere technology throughout the world, which, to some extent, cover VIVITROL and RISPERDAL CONSTA. The latest to expire of our patents covering RISPERDAL CONSTA expire in the U.S. in 2023 and expired in the EU in 2021.

Protection of Proprietary Rights and Competitive Position

We have exclusive rights through licensing agreements with third parties to issued U.S. patents, pending patent applications and corresponding patents or patent applications in countries outside the U.S, subject in certain instances to the rights of the U.S. government to use the technology covered by such patents and patent applications. Under certain licensing agreements, we are responsible for patent expenses, and we pay annual license fees and/or minimum annual royalties. In addition, under these licensing agreements, we are typically obligated to pay royalties on future sales of products, if any, covered by the licensed patents.

There may be patents issued to third parties that relate to our products or technologies. The manufacture, use, offer for sale, sale or import of some of our products might be found to infringe on the claims of these patents. A third party might file an infringement

19

Table of Contents

action against us. The cost of defending such an action is likely to be high, and we might not receive a favorable ruling. There may also be patent applications filed by third parties that relate to some of our products if issued in their present form. The patent laws of the U.S. and other countries are distinct, and decisions as to patenting, validity of patents and infringement of patents may be resolved differently in different countries.

If patents exist or are issued that cover our products or technologies, we or our licensees may not be able to manufacture, use, offer for sale, sell or import some of our products without first getting a license from the patent holder. The patent holder may not grant us a license on reasonable terms, or it may refuse to grant us a license at all. This could delay or prevent us from developing, manufacturing, selling or importing those of our products that would require the license.

We try to protect our proprietary position by filing patent applications in the U.S. and in other countries related to our proprietary technology, inventions and improvements that are important to the development of our business. Because the patent position of biopharmaceutical companies involves complex legal and factual questions, enforceability of patents cannot be predicted with certainty. The ultimate degree of patent protection that will be afforded to products and processes, including ours, in the U.S. and in other important markets, remains uncertain and is dependent upon the scope of protection decided upon by the patent offices, courts and lawmakers in these countries. Patents, if issued, may be challenged, invalidated or circumvented. Thus, any patents that we own or license from others may not provide any protection against competitors. Our pending patent applications, those we may file in the future, or those we may license from third parties, may not result in patents being issued. If issued, they may not provide us with proprietary protection or competitive advantages against competitors with similar technology. Furthermore, others may independently develop similar technologies or duplicate any technology that we have developed outside the scope of our patents. The laws of certain countries do not protect our intellectual property rights to the same extent as the laws of the U.S.

We also rely on trade secrets, know‑how and inventions, which are not protected by patents, to maintain our competitive position. We try to protect this information by entering into confidentiality agreements with parties that have access to it, such as our corporate partners, collaborators, licensees, employees and consultants. However, any of these parties may breach such agreements and may disclose our confidential information or our competitors might learn of the information in some other way. If any trade secret, know‑how or other invention not protected by a patent were to be disclosed to, or independently developed by, a competitor, such event could materially adversely affect our business, financial condition, cash flows and results of operations. For more information, see “Item 1A—Risk Factors” in this Annual Report.

Our trademarks, including VIVITROL, ARISTADA, ARISTADA INITIO and LYBALVI, are important to us and are generally covered by trademark applications or registrations with the U.S. Patent and Trademark Office and the patent or trademark offices of other countries. Our licensed products and products using our proprietary technologies also use trademarks that are owned by our licensees, such as the trademarks for INVEGA SUSTENNA/XEPLION, INVEGA TRINZA/TREVICTA, INVEGA HAFYERA/BYANNLI and RISPERDAL CONSTA, which are registered trademarks of Johnson & Johnson Corporation, VUMERITY, which is a registered trademark of Biogen (and used by Alkermes under license) and AMPYRA and FAMPYRA, which are registered trademarks of Acorda. Trademark protection varies in accordance with local law and continues in some countries as long as the trademark is used and in other countries as long as the trademark is registered. Trademark registrations generally are for fixed but renewable terms.

Regulatory

Regulation of Pharmaceutical Products

United States

Our current and contemplated activities, and the products and processes that result from such activities, are subject to substantial government regulation. Before new pharmaceutical products may be sold in the U.S., preclinical studies and clinical trials of the products must be conducted and the results submitted to the FDA for approval. Clinical trial programs must determine an appropriate dose and regimen, establish substantial evidence of effectiveness and define the conditions for safe use. This is a high‑risk process that requires stepwise clinical studies in which the product must successfully meet pre‑specified endpoints.

Preclinical Testing:  Before beginning testing of any compounds with potential therapeutic value in human subjects in the U.S., stringent government requirements for preclinical data must be satisfied. Preclinical testing includes both in vitro, or in an artificial environment outside of a living organism, and in vivo, or within a living organism, laboratory evaluation and characterization of the safety and efficacy of a drug and its formulation.

Investigational New Drug Exemption:  Preclinical testing results obtained from in vivo studies in several animal species, as well as from in vitro studies, are submitted to the FDA, as part of an Investigational New Drug Application (“IND”), and are reviewed by the FDA prior to the commencement of human clinical trials. The preclinical data must provide an adequate basis for evaluating both the safety and the scientific rationale for the initial clinical studies in human volunteers.

20

Table of Contents

Clinical Trials:  Clinical trials involve the administration of a drug to healthy human volunteers or to patients under the supervision of a qualified investigator pursuant to an FDA‑reviewed protocol. Human clinical trials are typically conducted in three sequential phases, although the phases may overlap with one another and, depending upon the nature of the clinical program, a specific phase or phases may be skipped altogether. Clinical trials must be conducted under protocols that detail the objectives of the study, the parameters to be used to monitor safety, and the efficacy criteria, if any, to be evaluated. Each protocol must be submitted to the FDA as part of the applicable IND.

In the U.S., the results of the preclinical and clinical testing of a product are then submitted to the FDA in the form of an NDA or a Biologics License Application (“BLA”). The NDA or BLA also include information pertaining to the preparation of the product, analytical methods, details of the manufacture of finished products and proposed product packaging and labeling. The submission of an application is not a guarantee that the FDA will find the application complete and accept it for filing. The FDA may refuse to file the application if it is not considered sufficiently complete to permit a review and will inform the applicant of the reason for the refusal. The applicant may then resubmit the application and include supplemental information.

Once an NDA or BLA is accepted for filing, the FDA has 10 months, under its standard review process, within which to review the application (for some applications, the review process is longer than 10 months). For drugs that, if approved, would represent a significant improvement in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications, the FDA may assign “priority review” designation and review the application within six months. The FDA has additional review pathways to expedite development and review of new drugs that are intended to treat serious or life‑threatening conditions and demonstrate the potential to address unmet medical needs, including: “Fast Track,” “Breakthrough Therapy,” and “Accelerated Approval.” However, none of these expedited pathways ensure that a product will receive FDA approval in a timely manner or at all.

As part of its review, the FDA may refer the application to an advisory committee for independent advice on questions related to the development of the drug, recommendation as to whether the application should be approved or other guidance that the FDA may seek. The FDA is not bound by the recommendation of an advisory committee; however, historically, it has often followed such recommendations. The FDA may determine that a Risk Evaluation and Mitigation Strategy (“REMS”) is necessary to ensure that the benefits of a new product outweigh its risks. If required, a REMS may include various elements, such as publication of a medication guide, a patient package insert, a communication plan to educate health care providers of the drug’s risks, limitations on who may prescribe or dispense the drug, or other measures that the FDA deems necessary to support the safe use of the drug.

In reviewing an NDA or BLA, the FDA may grant marketing approval, or issue a complete response letter to communicate to the applicant the reasons the application cannot be approved in its then-current form and provide input on the additional information that the FDA requires and/or changes that must be made before an application can be approved. Even if such additional information is submitted to the FDA or such changes made, the FDA may ultimately decide that the NDA or BLA still does not satisfy the FDA’s criteria for approval. The receipt of regulatory approval often takes a number of years, involves the expenditure of substantial resources and depends on a number of factors, including the severity of the disease in question, the availability of alternative treatments, efficacy and potential safety signals observed in preclinical tests or clinical trials, and the risks and benefits demonstrated in clinical trials. It is impossible to predict with any certainty whether and when the FDA will grant marketing approval for a given product. Even if a product is approved, the approval may be subject to limitations based on the FDA’s interpretation of the data. For example, the FDA may require, as a condition of approval, restricted distribution and use, enhanced labeling, special packaging or labeling, expedited reporting of certain adverse events, pre‑approval of promotional materials or restrictions on direct‑to‑consumer advertising, any of which could negatively impact the commercial success of a drug. The FDA may also require a sponsor to conduct additional post‑marketing studies as a condition of approval to provide data on safety and effectiveness. In addition, prior to commercialization, products that may be deemed controlled substances are subject to review and scheduling by the DEA.

The FDA tracks information on side effects and adverse events reported during clinical studies and after marketing approval. Non‑compliance with safety reporting requirements may result in civil or criminal penalties. Side effects or adverse events that are identified during clinical trials can delay, impede or prevent marketing approval. Based on new safety information that emerges after approval, the FDA can mandate product labeling changes, impose a REMS or the addition of elements to an existing REMS, require new post‑marketing studies (including additional clinical trials), or suspend or withdraw approval of the product.

If we seek to make certain types of changes to an approved product, such as adding a new indication, making certain manufacturing changes, or changing manufacturers or suppliers of certain ingredients or components, the FDA will need to review and approve such changes in advance. In the case of adding a new indication, we would be required to demonstrate with additional clinical data that the product is safe and effective for the new intended use. Such regulatory reviews can result in denial or modification of the

planned changes, or requirements to conduct additional tests or evaluations that can substantially delay or increase the cost of the planned changes.

In addition, the FDA regulates all advertising and promotional activities for products under its jurisdiction. A company can make only those claims relating to safety and efficacy that are consistent with FDA regulation and guidance. However, physicians may prescribe legally available drugs for uses that are not described in the drug’s labeling. Such off‑label uses are common across certain medical specialties and often reflect a physician’s belief that the off‑label use is the best treatment for a particular patient. The FDA does not regulate the behavior of physicians in their choice of treatments, but the FDA regulations do impose stringent restrictions on manufacturers’ communications regarding off‑label uses. Failure to comply with applicable FDA requirements may subject a company to adverse publicity, enforcement action by the FDA and the U.S. Department of Justice, corrective advertising and the full range of civil and criminal penalties available to the FDA and the U.S. Department of Justice.

Controlled Substances Act: The DEA regulates pharmaceutical products that are controlled substances. Controlled substances are those drugs that appear on one of the five schedules promulgated and administered by the DEA under the Controlled Substances Act (the “CSA”). The CSA governs, among other things, the inventory, distribution, recordkeeping, handling, security and disposal of controlled substances. For example, pharmaceutical products that act on the CNS are often evaluated for abuse potential; if a product is then classified as a controlled substance, it must undergo scheduling by the DEA, which is a separate process that may delay the commercial launch of such product even after FDA approval of the NDA for such product. Further, companies with a scheduled pharmaceutical product are subject to periodic and ongoing inspections by the DEA and similar state drug enforcement authorities to assess ongoing compliance with the DEA’s regulations. Any failure to comply with these regulations could lead to a variety of sanctions, including the revocation, or a denial of renewal, of any DEA registration and injunctions, or civil or criminal penalties.

Outside the United States

Certain of our products are commercialized by our licensees in numerous jurisdictions outside the U.S. Most of these jurisdictions have product approval and post‑approval regulatory processes that are similar in principle to those in the U.S. In Europe, there are several tracks for marketing approval, depending on the type of product for which approval is sought. Under the centralized procedure, a company submits a single application to the European Medicines Agency (“EMA”). The marketing application is similar to the NDA in the U.S. and is evaluated by the Committee for Medicinal Products for Human Use (“CHMP”), the expert scientific committee of the EMA. If the CHMP determines that the marketing application fulfills the requirements for quality, safety, and efficacy, it will submit a favorable opinion to the European Commission (“EC”). The CHMP opinion is not binding, but is typically adopted by the EC. A marketing application approved by the EC is valid in all member states.

In addition to the centralized procedure, Europe also has: (i) a nationalized procedure, which requires a separate application to, and approval determination by, each country; (ii) a decentralized procedure, whereby applicants submit identical applications to several countries and receive simultaneous approval; and (iii) a mutual recognition procedure, where applicants submit an application to one country for review and other countries may accept or reject the initial decision. Regardless of the approval process employed, various parties share responsibilities for the monitoring, detection and evaluation of adverse events post‑approval, including national authorities, the EMA, the EC, other relevant regulatory authorities and the marketing authorization holder.

Good Manufacturing Processes

The FDA, the EMA, the competent authorities of the EU member states and other regulatory agencies regulate and inspect equipment, facilities and processes used in the manufacturing of pharmaceutical and biologic products prior to approving a product. In 2020 and 2021, the COVID-19 pandemic has in some instances impacted the FDA’s and other regulatory agencies’ ability to conduct on-site inspections and has resulted in such agencies either delaying planned inspections or collecting the requisite information through review of written records in lieu of an on-site inspection, which in some instances has negatively impacted timelines for potential product approvals. Once approval from a regulatory agency is obtained, if a company makes a material change in manufacturing equipment, location or process, additional regulatory review and approval may be required. Companies also must adhere to cGMP and product-specific regulations enforced by the FDA and other regulatory agencies both in the manufacture of clinical product and following product approval. The FDA, the EMA and other regulatory agencies also conduct regular, periodic visits to re-inspect equipment, facilities and processes following the initial approval of a product and may also request that certain information or records be provided in writing for review in lieu of an on-site visit. If, as a result of these inspections or records reviews, it is determined that our equipment, facilities or processes do not comply with applicable regulations and conditions of product approval, regulatory agencies may seek civil, criminal or administrative sanctions and/or remedies against us, including the suspension of our manufacturing operations.

Good Clinical Practices

The FDA, the EMA and other regulatory agencies promulgate regulations and standards, commonly referred to as Good Clinical Practices (“GCP”), for designing, conducting, monitoring, auditing and reporting the results of clinical trials to ensure that the data and results are accurate and that the trial participants are adequately protected. The FDA, the EMA and other regulatory agencies enforce GCP through periodic inspections of trial sponsors, principal investigators, trial sites, contract research organizations (“CROs”) and institutional review boards. If our studies fail to comply with applicable GCP, patient safety and well-being could be impacted, the clinical data generated in our clinical trials may be deemed unreliable, and relevant regulatory agencies may require us to perform additional clinical trials before approving our marketing applications. Noncompliance can also result in civil or criminal sanctions. We rely on third parties, including CROs, to carry out many of our clinical trial‑related activities. Failure of such third parties to comply with GCP can likewise result in rejection of our clinical trial data or other sanctions.

Hatch‑Waxman Act

Under the U.S. Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch‑Waxman Act”), Congress created an abbreviated FDA review process for generic versions of pioneer, or brand‑name, drug products. The law also provides incentives by awarding, in certain circumstances, non‑patent related marketing exclusivities to pioneer drug manufacturers. Newly approved drug products and changes to the conditions of use of approved products may benefit from periods of non‑patent‑related marketing exclusivity in addition to any patent protection the drug product may have. The Hatch‑Waxman Act provides five years of new chemical entity (“NCE”) marketing exclusivity to the first applicant to gain approval of an NDA for a product that contains an active ingredient, known as the active drug moiety, not found in any other approved product. The FDA is prohibited from accepting any ANDA for a generic drug or 505(b)(2) application referencing the NCE for five years from the date of approval of the NCE, or four years in the case of an ANDA or 505(b)(2) application containing a patent challenge, and in both cases may not approve such generic drug or 505(b)(2) application until expiration of NCE marketing exclusivity. A 505(b)(2) application is an NDA in which the applicant relies, in part, on data and the FDA’s findings of safety and efficacy from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference. Hatch-Waxman Act exclusivities will not prevent the submission or approval of a full NDA (e.g., under 505(b)(1)), as opposed to an ANDA or 505(b)(2) application, for any drug, including, for example, a drug with the same active ingredient, dosage form, route of administration, strength and conditions of use.

The Hatch‑Waxman Act also provides three years of exclusivity for applications containing the results of new clinical investigations, other than bioavailability studies, essential to the FDA’s approval of new uses of approved products, such as new indications, dosage forms, strengths, or conditions of use. However, this exclusivity only protects against the approval of ANDAs and 505(b)(2) applications for the protected use and will not prohibit the FDA from accepting or approving ANDAs or 505(b)(2) applications for other products containing the same active ingredient.

The Hatch‑Waxman Act requires NDA applicants and NDA holders to provide certain information about patents related to the drug for listing in the FDA’s Approved Drugs Product List, commonly referred to as the Orange Book. ANDA and 505(b)(2) applicants must then certify regarding each of the patents listed with the FDA for the reference product. A certification that a listed patent is invalid or will not be infringed by the marketing of the applicant’s product is called a “Paragraph IV certification.” If the ANDA or 505(b)(2) applicant provides such a notification of patent invalidity or noninfringement, then the FDA may accept the ANDA or 505(b)(2) application four years after approval of the NDA for an NCE. If a Paragraph IV certification is filed and the ANDA or 505(b)(2) application has been accepted as a reviewable filing by the FDA, the ANDA or 505(b)(2) applicant must then, within 20 days, provide notice to the NDA holder and patent owner stating that the application has been submitted and providing the factual and legal basis for the applicant’s opinion that the patent is invalid or not infringed. The NDA holder or patent owner may file suit against the ANDA or 505(b)(2) applicant for patent infringement. If this is done within 45 days of receiving notice of the Paragraph IV certification, a one‑time, 30‑month stay of the FDA’s ability to approve the ANDA or 505(b)(2) application is triggered. The 30‑month stay begins at the end of the NDA holder’s data exclusivity period, or, if data exclusivity has expired, on the date that the patent holder is notified. The FDA may approve the proposed product before the expiration of the 30‑month stay if a court finds the patent invalid or not infringed, or if the court shortens the period because the parties have failed to cooperate in expediting the litigation.

Sales and Marketing

We are subject to various U.S. federal and state laws pertaining to healthcare fraud and abuse, including anti-kickback laws and false claims laws. Anti‑kickback laws make it illegal for a prescription drug manufacturer to solicit, offer, receive, or pay any remuneration in exchange for, or to induce, the referral of business, including the purchase or prescription of a particular drug. Due to the broad scope of the U.S. statutory provisions, the general absence of guidance in the form of regulations, and few court decisions addressing industry practices, it is possible that our practices might be challenged under anti‑kickback or similar laws. False claims laws prohibit anyone from knowingly and willingly presenting, or causing to be presented, for payment to third‑party payers (including Medicare and Medicaid) claims for reimbursed drugs or services that are false or fraudulent, claims for items or services not provided as claimed or claims for medically unnecessary items or services. Activities relating to the sale and marketing of our

23

Table of Contents

products may be subject to scrutiny under these laws. Violations of fraud and abuse laws may be punishable by criminal and/or civil sanctions, including fines and civil monetary penalties, as well as the possibility of exclusion from federal healthcare programs (including Medicare and Medicaid). In addition, federal and state authorities are paying increased attention to enforcement of these laws within the pharmaceutical industry and private individuals have been active in alleging violations of the laws and bringing suits on behalf of the U.S. government under the False Claims Act. If we were subject to allegations concerning, or were convicted of violating, these laws, our business could be harmed. See “Item 1A—Risk Factors” in this Annual Report and specifically those sections entitled “If there are changes in, or we fail to comply with, the extensive legal and regulatory requirements affecting the healthcare industry, we could face costs, penalties and business losses,” “Revenues generated by sales of our products depend on the availability from third-party payers of reimbursement for our products and the extent of cost-sharing arrangements for patients (e.g., patient co-payment, co-insurance, deductible obligations) and cost-control measures imposed, and any reductions in payment rate or reimbursement or increases in our or in patients’ financial obligation to payers could result in decreased sales of our products and/or decreased revenues” and “The clinical study or commercial use of our products may cause unintended side effects or adverse reactions, or incidents of misuse may occur, which could adversely affect our products, business and share price.”

Laws and regulations have been enacted by the U.S. federal government and various states to regulate the sales and marketing practices of pharmaceutical manufacturers. The laws and regulations generally limit financial interactions between manufacturers and healthcare providers and require disclosure to the government and public of such interactions. The laws include federal “sunshine”, or open payments, provisions enacted in 2010 as part of the comprehensive federal healthcare reform legislation and supplemented as part of the Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act. Such provisions apply to pharmaceutical manufacturers with products reimbursed under certain government programs and require those manufacturers to disclose annually to the federal government (for re‑disclosure to the public) certain payments made to, or at the request of, or on behalf of, physicians or to teaching hospitals and, commencing for information to be submitted as of January 1, 2022, certain payments made to physicians assistants, nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists and certified nurse-midwives. Certain state laws also require disclosure of pharmaceutical pricing information and marketing expenditures. Given the ambiguity found in many of these laws and their implementation, our reporting actions could be subject to the penalty provisions of the pertinent U.S. federal and state laws and regulations.

Pricing and Reimbursement

United States

In the U.S., sales of our products, including those sold by our licensees, and our ability to generate revenues on such sales are dependent, in significant part, on the availability and level of reimbursement from third‑party payers such as state and federal governments, including Medicare and Medicaid, managed care providers and private insurance plans. Third‑party payers are increasingly challenging the prices charged for medical products and examining the medical necessity and cost‑effectiveness of medical products, in addition to their safety and efficacy.

Medicaid is a joint federal and state program that is administered by the states for low‑income and disabled beneficiaries. Under the Medicaid rebate program, we are required to pay a rebate for each unit of product reimbursed by the state Medicaid programs. The amount of the rebate for each product is set by law as the greater of 23.1% of average manufacturer price (“AMP”) or the difference between AMP and the best price available from us to any commercial or non‑federal governmental customer. The rebate amount must be adjusted upward where the AMP for a product’s first full quarter of sales, when adjusted for increases in the Consumer Price Index—Urban, is less than the AMP for the current quarter, with this difference being the amount by which the rebate is adjusted upwards. The rebate amount is required to be recomputed each quarter based on our report of current AMP and best price for each of our products to the Centers for Medicare & Medicaid Services (“CMS”). The terms of our participation in the rebate program imposes a requirement on us to report revisions to AMP or best price within a period not to exceed 12 quarters from the quarter in which the data was originally due. Any such revisions could have the impact of increasing or decreasing our rebate liability for prior quarters, depending on the direction of the revision. In addition, if we were found to have knowingly submitted false information to the government, the statute provides for civil monetary penalties per item of false information in addition to other penalties available to the government.

Medicare is a federal program that is administered by the federal government that covers individuals age 65 and over as well as those with certain disabilities. Medicare Part B pays physicians who administer our products under a payment methodology using average sales price (“ASP”) information. Manufacturers, including us, are required to provide ASP information to the CMS on a quarterly basis. This information is used to compute Medicare payment rates, with rates for Medicare Part B drugs outside the hospital outpatient setting and in the hospital outpatient setting consisting of ASP plus a specified percentage. These rates are adjusted periodically. If a manufacturer is found to have made a misrepresentation in the reporting of ASP, the statute provides for civil monetary penalties for each misrepresentation and for each day in which the misrepresentation was applied.

Medicare Part D provides coverage to enrolled Medicare patients for self‑administered drugs (i.e. drugs that do not need to be injected or otherwise administered by a physician) and certain physician-administered drugs reimbursed under a pharmacy benefit. Medicare Part D also covers the prescription drug benefit for dual eligible beneficiaries. Medicare Part D is administered by private prescription drug plans approved by the U.S. government and each drug plan establishes its own Medicare Part D formulary for prescription drug coverage and pricing, which the drug plan may modify from time‑to‑time. The prescription drug plans negotiate pricing with manufacturers and may condition formulary placement on the availability of manufacturer discounts. Except for dual eligible Medicare Part D beneficiaries who qualify for low-income subsidies, manufacturers, including us, are required to provide a seventy percent (70%) discount on our brand name prescription drugs utilized by Medicare Part D beneficiaries when those beneficiaries reach the coverage gap in their drug benefits.

The availability of federal funds to pay for our products under the Medicaid Drug Rebate Program and Medicare Part B requires that we extend discounts to certain purchasers under the Public Health Services (including the Indian Health Services, “PHS”) pharmaceutical pricing program. Purchasers eligible for discounts include a variety of community health clinics, other entities that receive health services grants from PHS, and hospitals that serve a disproportionate share of financially needy patients.

We also make our products available for purchase by authorized users of the Federal Supply Schedule (“FSS”) of the General Services Administration pursuant to our FSS contract with the Department of Veterans Affairs. Under the Veterans Health Care Act of 1992 (the “VHC Act”), we are required to offer deeply discounted FSS contract pricing to four federal agencies: the Department of Veterans Affairs; the Department of Defense; the Coast Guard; and the PHS, in order for federal funding to be made available for reimbursement of any of our products by such federal agencies and certain federal grantees. Coverage under Medicaid, the Medicare Part B program and the PHS pharmaceutical pricing program is also conditioned upon FSS participation. FSS pricing is negotiated periodically with the Department of Veterans Affairs. FSS pricing is intended not to exceed the price that we charge our most‑favored non‑federal customer for a product. In addition, prices for drugs purchased by the Department of Veterans Affairs, Department of Defense (including drugs purchased by military personnel and dependents through the TriCare retail pharmacy program), Coast Guard and PHS are subject to a cap on pricing equal to 76% of the non‑federal average manufacturer price (“non‑FAMP”). An additional discount applies if non‑FAMP increases more than inflation (measured by the Consumer Price Index—Urban). In addition, if we are found to have knowingly submitted false information to the government, the VHC Act provides for civil monetary penalties per false item of information in addition to other penalties available to the government.

In addition, on January 21, 2016, CMS released the final Medicaid covered outpatient drug regulation, which became effective on April 1, 2016. This regulation implements those changes made by the Patient Protection and Affordable Care Act (the “PPACA”) to the Medicaid drug rebate statute in 2010 and addresses a number of other issues with respect to the Medicaid program, including, but not limited to, the eligibility and calculation methodologies for AMP and best price, and the expansion of Medicaid rebate liability to include Medicaid managed care organizations. The final Medicaid covered outpatient drug regulation established two calculation methodologies for AMP: one for drugs generally dispensed through retail community pharmacies (“RCP”) and one for so-called “5i drugs” (inhaled, infused, instilled, implanted or injectable drugs) “not generally dispensed” through RCPs. The regulation further made clear that 5i drugs would qualify as “not generally dispensed” and, therefore, able to use the alternative AMP calculation, if not more than thirty percent (30%) of their sales were to RCPs or to wholesalers for RCPs. The primary difference between the two AMP calculations is the requirement to exclude from AMP, for those qualifying 5i drugs not generally dispensed through RCPs, certain payments, rebates and discounts related to sales to non-RCPs; such exclusion often leads to a lower AMP. The decision of which AMP calculation a product is eligible to use must be made and applied on a monthly basis based on the percentage of sales of such product to RCPs or to wholesalers for RCPs.

U.S. federal and state governments regularly consider reforming healthcare coverage and lessening healthcare costs. Such reforms may include price controls, value-based pricing and changes to the coverage and reimbursement of our products, which may have a significant impact on our business. For example, in November 2021, the U.S. House of Representatives passed H.R. 5376, the Build Back Better Act (the “BBBA”). The BBBA includes several provisions that may impact our business, including provisions that create an out-of-pocket cap for seniors, implement a new manufacturer liability (including in Medicare Part D), allow the U.S. government to negotiate prices for some drugs covered under Medicare Part B and Part D, require inflation rebates to limit annual increases in drug prices in Medicare and private insurance, and repeal the rebate rule that would require pass through of pharmacy benefit manager rebates to beneficiaries. In addition, emphasis on managed care in the U.S. has increased and we expect will continue to increase the pressure on drug pricing. Private insurers regularly seek to manage drug cost and utilization by implementing coverage and reimbursement limitations through means including, but not limited to, formularies, increased out‑of‑pocket obligations and various prior authorization requirements. Even if favorable coverage and reimbursement status is attained for one or more products for which we have received regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Outside the United States

Within the EU, products are paid for by a variety of payers, with governments being the primary source of payment. Governments may determine or influence reimbursement of products. Governments may also set prices or otherwise regulate pricing. Negotiating prices with governmental authorities can delay commercialization of products. Governments may use a variety of cost‑containment measures to control the cost of products, including price cuts, mandatory rebates, value‑based pricing and reference pricing (i.e., referencing prices in other countries and using those reference prices to set a price). Recent budgetary pressures in many EU countries are causing governments to consider or implement various cost‑containment measures, such as price freezes, increased price cuts and rebates, and expanded generic substitution and patient cost‑sharing. If budget pressures continue, governments may implement additional cost‑containment measures.

Other Regulations

Foreign Corrupt Practices Act: We are subject to the U.S. Foreign Corrupt Practices Act (the “FCPA”), which prohibits U.S. corporations and their representatives from paying, offering to pay, promising, authorizing, or making payments of anything of value to any foreign government official, government staff member, political party, or political candidate in an attempt to obtain or retain business or to otherwise influence a person working in an official capacity. In many countries, the healthcare professionals with whom we regularly interact may meet the FCPA’s definition of a foreign government official. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect their transactions and to devise and maintain an adequate system of internal accounting controls.

Environmental, Health and Safety Laws: Our operations are subject to complex and increasingly stringent environmental, health and safety laws and regulations in the countries where we operate and, in particular, where we have manufacturing facilities, namely the U.S. and Ireland. Environmental and health and safety authorities in the relevant jurisdictions, including the Environmental Protection Agency and the Occupational Safety and Health Administration in the U.S. and the Environmental Protection Agency and the Health and Safety Authority in Ireland, administer laws which regulate, among other matters, the emission of pollutants into the air (including the workplace), the discharge of pollutants into bodies of water, the storage, use, handling and disposal of hazardous substances, the exposure of persons to hazardous substances, and the general health, safety and welfare of employees and members of the public. In certain cases, these laws and regulations may impose strict liability for pollution of the environment and contamination resulting from spills, disposals or other releases of hazardous substances or waste and/or any migration of such hazardous substances or waste. Costs, damages and/or fines may result from the presence, investigation and remediation of contamination at properties currently or formerly owned, leased or operated by us and/or off‑site locations, including where we have arranged for the disposal of hazardous substances or waste. In addition, we may be subject to third‑party claims, including for natural resource damages, personal injury and property damage, in connection with such contamination.

The General Data Protection Regulation (“GDPR”): The GDPR became effective on May 25, 2018 and replaced the previous EU Data Protection Directive (95/46). The GDPR, which governs the processing of personal data (including personal health data), applies to the Company and any of its subsidiaries that are established in the EU to the extent that they process personal data as well as any of its subsidiaries that are established outside the EU to the extent that they process personal data relating to EU residents for certain purposes, including any such data relating to clinical trial participants in the EU. The GDPR imposes significant obligations on controllers and processors of personal data, including high standards for obtaining consent from individuals to process their personal data, robust notification requirements to individuals about the processing of their personal data, a strong individual data rights regime, mandatory data breach notifications, limitations on the retention of personal data, stringent requirements pertaining to health data, and strict rules and restrictions on the transfer of personal data outside of the EU, including to the U.S. The GDPR also imposes additional obligations on, and required contractual provisions to be included in, contracts between companies subject to the GDPR and their third-party processors that relate to the processing of personal data. The GDPR allows EU member states to make additional laws and regulations in order to introduce further conditions, including limitations, with regard to the processing of genetic, biometric or health data.

Other Laws: We are subject to a variety of financial disclosure, securities trading regulations and governmental regulations as an Irish-incorporated company publicly-listed in the U.S., including laws relating to the oversight activities of the SEC, the Irish Companies Act 2014, and the regulations of the Nasdaq Stock Market (“Nasdaq”), on which our shares are traded. We are also subject to various laws, regulations and recommendations relating to safe working conditions, laboratory practices, the experimental use of animals, and the purchase, storage, movement, import and export and use and disposal of hazardous or potentially hazardous substances used in connection with our research work.

Human Capital Resources

As a global biopharmaceutical company focused on developing innovative medicines in the fields of neuroscience and oncology, we have built, and continue to devote significant resources to further develop and enhance, a comprehensive cross-functional infrastructure designed to support product development from discovery through commercialization and lifecycle management. We seek to attract, hire, develop, recognize and retain qualified and highly skilled personnel with experience in areas

26

Table of Contents

such as R&D, including early discovery, translational medicine, formulation and clinical development capabilities; intellectual property prosecution, enforcement and defense; medical affairs; manufacturing operations; U.S. federal and state government affairs; sales and marketing; and market access. Competition for such personnel in our industry and the geographic regions in which we operate is intense, with numerous companies also developing, launching or marketing products, including products against which our products directly compete. Supporting our employees’ well-being in a transparent, diverse, inclusive, and collaborative culture and providing them with the training, support and resources they need to succeed professionally, while appropriately balancing their professional and personal lives, helps keep our employees connected and engaged and is critical to our success.

As of February 4, 2022, we had approximately 2,211 full time employees, of which approximately 1,798 were based in the U.S. and 413 were based in Ireland. Our 2021 global voluntary attrition rate was below industry benchmarks. None of our employees are covered by a collective bargaining agreement, and we consider our relations with our employees to be good.

We are an equal opportunity employer and we are fundamentally committed to creating and maintaining a work environment in which employees are treated with respect and dignity. All human resources policies, practices and actions related to hiring, promotion, compensation, benefits and termination are administered in accordance with the principles of equal employment opportunity and other legitimate criteria without regard to race, color, religion, sex, sexual orientation, gender expression or identity, ethnicity, national origin, ancestry, age, mental or physical disability, genetic information, any veteran status, any military status or application for military service, or membership in any other category protected under applicable laws.

Recognizing the value of our employees and their important contributions to the achievement of our business objectives, we offer market-competitive comprehensive total rewards packages, including bonus opportunities at all levels tied to individual and company performance, and for employees at certain levels, company equity opportunities. We are committed to designing and managing our pay programs and decisions to support equitable pay for all employees. We have established our compensation programs based on market and benchmark data and strive to pay all employees equitably, taking into consideration factors such as their role, skills, abilities and relevant experience. We also offer healthcare and retirement savings plan benefits, paid time off, tuition reimbursement and other benefits designed to support healthy lifestyle choices, financial wellness and work-life balance.

Across all of our sites, we cultivate a work environment that reflects our values of collaboration at our core, respect for each voice and unwavering commitment. Over the past several years, we have continued to focus on fostering an environment that respects and celebrates Diversity, Inclusion & Belonging (“DIB”) in our workplaces and our communities and have actively evolved our DIB strategy to cater to the changing needs of our employees and respond to important external social and cultural events.  In support of this strategy, in 2019, we created a global cross-functional DIB Steering Committee, comprised of representatives from all of our locations, including field-based employees, to create connections, foster conversations, help ensure our efforts are aligned with the diverse range of perspectives within our organization and develop and advance practices, tools and resources that can be used to strengthen the sense of belonging among our employee base. Since 2020, we have established five Employee Resource Groups (ERGs): Limitless, a network for individuals with disabilities and caregivers; Mosaic, a multicultural network; Operation Salute, a veterans network; Pride@Work, an LGBTQ+ network; and Women Inspired Network (WIN), a women’s network. These ERGs share a common purpose of supporting and enhancing the inclusiveness of our company culture and providing opportunities for professional development, networking and building deeper connections within Alkermes. In 2021, we established a DIB Executive Committee, which includes our Chief Executive Officer and other senior leaders, to continue to refine our DIB strategy and champion its implementation and impact across the business.  These groups work together to set goals, establish and execute strategic initiatives, measure our progress and promote a culture of understanding and inclusion throughout our organization.  Additionally, as part of our increased focus on social and racial justice, diversity and inclusion, and in response to global events throughout 2020 and 2021, we held company-wide town hall conversations, sponsored recognition events and enhanced our Company’s diversity education and training.

We strive to foster a strong culture of active employee engagement to ensure that employees feel part of our mission and that they have a voice in the Alkermes community. Since 2017, we have conducted annual employee engagement surveys to understand employee sentiment regarding, and satisfaction with, their work and experience at Alkermes. In 2021, over 70% of our employees participated in our employee engagement survey and we have used the data collected to help inform and evolve our human capital management strategy and initiatives.

We are committed to the professional growth and development of our employees. We conduct a comprehensive on-boarding experience that connects newly hired employees to our business, values, culture, and people. We encourage and support our employees in their adoption of Individual Development Plans designed to identify professional development and growth opportunities to help support their career aspirations. We frequently organize company-hosted trainings that cover topics including performance management, collaboration, leadership development, diversity, communication, and mentorship, and more specialized skills-based programs.  In 2021, we launched a new LinkedIn Learning platform to provide on-demand learning opportunities to our employees.  Since we made this platform available, our employees have, in the aggregate, viewed over 14,000 courses on a wide variety of topics.

Our culture is one of collaboration and trust. We ask our employees to help us promote and provide workplace environments that are safe and protective of the health and well-being of our people and in compliance with applicable laws, rules and regulations. We maintain extensive environmental, health safety and security policies, adhere to all health and safety standards set by regulators in the locations in which we operate and routinely train employees and monitor our sites to reduce the risk of workplace accidents.

In 2021, employee health, safety and wellness continued to be of particular focus and importance for the Company. Following the emergence of the COVID-19 pandemic, we adopted a series of precautionary measures to protect and support our employees, including those performing essential tasks in our laboratories and manufacturing facilities who could not perform their work remotely. In 2021, we adjusted our communication strategies to keep employees connected and informed, including increased communications from leadership and frequent online surveys to measure employee experiences and the effectiveness of our communications. We also enhanced employee resources, including wellness and stress-reduction resources, guidance on how to effectively engage and work remotely, and increased childcare benefits.  For additional information about actions taken by the Company to support its employees and other stakeholders in response to the COVID-19 pandemic, see the “COVID-19 Update” included in “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Annual Report.

Item 1A. Risk Factors

You should consider carefully the risks described below in addition to the financial and other information contained in this Annual Report, including the matters addressed under the caption “Cautionary Note Concerning Forward-Looking Statements.” If any events described by the following risks actually occur, they could materially adversely affect our business, financial condition, cash flows or results of operations. This could cause the market price of our ordinary shares to decline.

Risks Related to Our Business and Our Industry

Our business, financial condition and results of operations have been, and may continue to be, adversely affected by the ongoing COVID-19 pandemic or other similar outbreaks of contagious diseases.

Outbreaks of contagious diseases and other adverse public health developments affecting us and/or the third parties on which we rely, could have a material and adverse effect on our business, financial condition and results of operations. The COVID-19 pandemic has impacted, and is continuing to impact, many aspects of society, including the operation of healthcare systems, global travel, supply and labor markets and other business and economic activity worldwide. Ireland, all U.S. states, and many local jurisdictions and countries around the world have, at times during the pandemic, issued and implemented quarantines, vaccine and masking mandates, executive orders and other similar government orders, restrictions and recommendations for their residents to help control the spread of COVID-19. Such orders, mandates, restrictions and/or recommendations have, at times during the pandemic, resulted in widespread interruptions and closures of businesses, including healthcare systems that serve people living with addiction and serious mental illness, work stoppages, slowdowns and/or delays, remote work policies and travel restrictions, among other effects.

The COVID-19 pandemic has had, and may continue to have, an adverse impact on our financial condition and results of operations. For example, commercial sales of the medicines from which we derive revenue— including injectable medications administered by healthcare professionals—have been, and we expect will continue to be, adversely impacted as a result of developments that have transpired, and may continue to transpire, related to this pandemic, including travel restrictions, quarantine, testing and/or vaccine mandates and other protocols, and labor shortages, many of which have contributed to limited access to, or reduced willingness to access, healthcare providers and locations where injectable medications may be administered. Further, this pandemic and measures to mitigate the spread of COVID-19 have had, and may continue to have, an adverse effect on global economic conditions, which could have an adverse effect on our business and financial condition, including the demand for, and ability of patients to access, our and our licensees’ medicines, or our ability to obtain financing, if needed, on favorable terms or at all.

The COVID-19 pandemic has caused, and may continue to cause, varying degrees of disruption to our employees, our communities and our business operations. While we have continued to operate our manufacturing facilities and to supply our medicines without interruption throughout the pandemic, any prolonged labor or supply chain shortages at our manufacturing facilities could impact our ability to manufacture our products and the third-party products from which we receive revenue in a timely matter or at all. In addition, while we have continued to conduct our R&D activities, including our ongoing clinical trials, the COVID-19 pandemic has, at times, impacted the timelines of certain of our early-stage discovery efforts and clinical trials, and may continue to impact such timelines while the pandemic persists. We work with our internal teams, our clinical investigators, R&D vendors and critical supply chain vendors to continually assess, and endeavor to mitigate, potential adverse impacts of COVID-19 on our manufacturing operations and R&D activities.

In addition, we rely upon third parties for many aspects of our business, including the provision of goods and services related to the manufacture of our clinical products and our and our partners’ marketed products, the conduct of our clinical trials, and the sale of our proprietary marketed products and the marketed products of our licensees from which we receive manufacturing and/or royalty revenue. The COVID-19 pandemic has, to varying degrees, disrupted the business operations of the third parties on which we rely, including our suppliers, packagers, distributors, contract research organizations, customers, clinical site investigators, community advocacy partners, and others, and may continue to do so for so long as the pandemic and its impacts persist. For example, the third-party sites and investigators involved in our clinical trials have experienced, and may continue to experience, interruptions which have impacted, and may continue to impact, the conduct of our clinical trials and our ability to complete them in a timely manner or at all. If our clinical programs are significantly delayed as a result of such impacts, there could be adverse effects on our expected timelines for regulatory review and potential approval of our product candidates. Any prolonged material disruption to these or other third parties on which we rely could negatively impact our ability to conduct business in the manner and on the timelines presently planned, which could have a material adverse impact on our business, results of operations and financial condition.

The COVID-19 pandemic has also impacted, and may continue to impact, the regulatory agencies with which we interact in the development, manufacture, regulatory review and commercialization of our medicines. For example, travel restrictions, social distancing, quarantine protocols and other protective measures may impact the timelines and manner in which the FDA, the HPRA and other regulatory agencies conduct regulatory activities, which may, in turn, negatively impact expected timelines for regulatory review and approval of our product candidates, which could have an adverse effect on our business and the market price for our ordinary shares.

The degree to which the ongoing COVID-19 pandemic may continue to impact our employees, business, financial condition and results of operations will depend on the ultimate severity and duration of the pandemic and the manner in which it continues to evolve, including the emergence, prevalence and severity of new COVID-19 variants, and future developments in response thereto, which are highly uncertain and cannot be predicted as of the date of this Annual Report and which may include, among other things, governmental, business or other actions that have been, are being or will be taken in response to this pandemic, such as restrictions on travel and mobility, business closures and operating restrictions, the imposition of vaccine and masking mandates and/or mandatory testing protocols. We are unable to predict the impacts of the pandemic and of actions taken in response to the pandemic, on our employees, including with regard to their health, safety, wellbeing and job performance, or on the labor market and our ability to attract and retain employees; impacts of the pandemic on the vendors or distribution channels in our supply chain and on our ability to continue to manufacture and supply our products; impacts of the pandemic on the conduct of our clinical trials, including with respect to enrollment rates, availability of investigators and clinical trial sites, and monitoring of data; impacts of the pandemic on healthcare systems that serve people living with opioid dependence, alcohol dependence, schizophrenia and bipolar I disorder; impacts of the pandemic on the regulatory agencies with which we interact in the development, review, approval and commercialization of our medicines; impacts of the pandemic on reimbursement for our products, including our Medicaid rebate liability, and for services related to the use of our products; and impacts of the pandemic on the U.S., Irish and global economies more broadly.

We receive substantial revenue from our key proprietary products and our success depends on our ability to successfully manufacture and commercialize such products.

Sales of our proprietary products comprise an increasingly significant portion of our revenues. We developed and exclusively manufacture VIVITROL for the treatment of alcohol dependence and opioid dependence, ARISTADA for the treatment of schizophrenia, ARISTADA INITIO for initiation onto ARISTADA for the treatment of schizophrenia, and LYBALVI for the treatment of adults with schizophrenia and for the treatment of adults with bipolar I disorder, as a maintenance monotherapy or for the acute treatment of manic or mixed episodes, as monotherapy or an adjunct to lithium or valproate, and we exclusively commercialize these products in the U.S. Our success depends in large part on our ability to continue to successfully manufacture and commercialize such products in the complex markets into which they are sold. Any significant negative developments relating to these products could have a material adverse effect on our revenues from these products and, in turn, on our business, financial condition, cash flows and results of operations and the market price of our ordinary shares.

We rely heavily on our licensees in the commercialization and continued development of products from which we receive revenue and, if our licensees are not effective, or if disputes arise in respect of our contractual arrangements, our revenues could be materially adversely affected.

Our arrangements with licensees are critical to bringing to market and/or successfully commercializing products using our proprietary technologies and from which we receive manufacturing and/or royalty revenue. We rely on these licensees in various respects, including commercializing such products, conducting development activities with respect to new formulations or new indications for such products, and/or managing the regulatory approval process for such products.

We earn significant royalty and/or manufacturing revenue from sales by our licensees of our licensed products and third-party products incorporating our proprietary technologies. The revenues we receive from such products depend primarily upon the success of our licensees in commercializing such products. For example, we receive substantial revenue from Janssen’s sales of the long-acting INVEGA products and RISPERDAL CONSTA and from Biogen’s sales of VUMERITY and FAMPYRA. We have no involvement in the commercialization efforts for these and other products sold by third parties from which we receive revenue and cannot control the extent or effectiveness of such commercialization efforts.

Disputes may also arise between us and a licensee involving the ownership of technology developed under a license, the use of our technology, including know-how, in third-party products, the terms and amounts of royalty payments to be paid under a license, or other issues arising out of any licenses or other collaborative agreements. Such disputes may delay related development programs, impact commercialization or manufacturing activities for the related products, impact the timing or amount of revenue that we receive in respect of such products, or result in expensive arbitration, litigation or other dispute resolution, which may not be resolved in our favor and may adversely impact our financial condition. Further, certain of our license agreements may be terminated, with or without cause, or assigned in connection with a change in control, and we cannot guarantee that any of these relationships will continue or that our licensees will be able or willing to continue to perform their obligations, including development, commercialization or payment obligations, under such agreements. Any significant negative developments relating to our relationships with our licensees or our collaborative arrangements could have a material adverse effect on our business, financial condition, cash flows and results of operations.

For example, in November 2021 we received notice of partial termination in the U.S. of our license agreement with Janssen related to INVEGA SUSTENNA, INVEGA TRINZA, and INVEGA HAFYERA. The basis for this termination is Janssen’s assertion that it does not utilize our NanoCrystal technology licensed under the license agreement. We strongly disagree with Janssen’s position and are prepared to pursue all options at our disposal to enforce our contractual rights and address any unauthorized use of our intellectual property; however, the announcement of Janssen’s partial termination and expectations regarding the loss of royalty revenues from U.S. sales of such products in early 2022 resulting from such termination, caused the market price of our ordinary

30

Table of Contents

shares to decline significantly, and any actual losses of royalty revenues that result from such termination, and/or prolonged discussions, dispute resolution efforts or commercial arbitration or litigation in respect of such royalty revenues, could have a material adverse effect on our business, financial condition, cash flows and results of operations.

For these and other reasons that may be outside of our control, our revenues from products sold by our licensees may fall below our expectations, the expectations of our licensees or those of our shareholders, which could have a material adverse effect on our results of operations and the market price of our ordinary shares.

We face competition in the biopharmaceutical industry.

We face intense competition in the development, manufacture, marketing and commercialization of our products from many and varied sources, such as research institutions and other biopharmaceutical companies, including companies with similar technologies or medicines, and manufacturers of generic drugs. Some of these competitors are also our licensees, who control the commercialization of products from which we receive manufacturing and/or royalty revenues. For example, our proprietary products ARISTADA and LYBALVI compete with the long-acting INVEGA products and RISPERDAL CONSTA, products from which we receive manufacturing and/or royalty revenues.

The biopharmaceutical industry is characterized by intensive research, development and commercialization efforts and rapid and significant technological change. In many cases, there are already products on the market that may be in direct competition with our commercial products or products in development. In addition, there are many companies developing generic versions of our products, or products with similar technologies to ours or for use in similar indications with whom we and our licensees compete, many of whom are larger and have significantly greater financial and other resources than we do. Other smaller or earlier stage companies may also prove to be significant competitors, particularly through focused development programs and collaborative arrangements with large, established companies. Some of the products being developed by our competitors are being designed to work differently than our products and may turn out to be safer or more effective than our products, which may render our products or technology platforms obsolete or noncompetitive. For a detailed discussion of the competition that we face with respect to our current marketed products, technology platforms and product indications, please see the section entitled “Competition” in “Item 1—Business” in this Annual Report. If we are unable to compete successfully in this highly competitive biopharmaceutical industry, our business, financial condition, cash flows and results of operations could be materially adversely affected.

Our revenues may decrease or grow at a slower than expected rate due to many factors.

We cannot be assured that our products will be, or will continue to be, accepted in the U.S. or markets outside the U.S. or that we will be able to maintain or increase sales of our products. Factors that may cause revenues from our products to grow at a slower than expected rate, decrease or cease all together, include, among others:

31

Table of Contents

Revenues generated by sales of our products depend on the availability from third-party payers of reimbursement for our products and the extent of cost-sharing arrangements for patients (e.g., patient co-payment, co-insurance, deductible obligations) and cost-control measures imposed, and any reductions in payment rate or reimbursement or increases in our or in patients’ financial obligation to payers could result in decreased sales of our products and/or decreased revenues.

In both U.S. and non-U.S. markets, sales of our products depend, in part, on the availability of reimbursement from third-party payers such as state and federal governments, including Medicare and Medicaid in the U.S. and similar programs in other countries, managed care providers and private insurance plans. Deterioration in the timeliness, certainty and amount of reimbursement for our products, the existence of barriers to coverage of our products (such as prior authorization, criteria for use or other requirements), increases in our financial obligation to payers, including government payers, limitations by healthcare providers on how much, or under what circumstances, they will prescribe or administer our products or unwillingness by patients to pay any required co-payments, or deductible amounts, could reduce the use of, and revenues generated from, our products and could have a material adverse effect on our business, financial condition, cash flows and results of operations. In addition, when a new product is approved, the availability of government and private reimbursement for that product and coverage restrictions that may be imposed for such product, are uncertain, as is the amount for which that product will be reimbursed. We cannot predict the availability or amount of reimbursement for, or the prevalence and extent of other access barriers to, our products.

In the U.S., federal and state legislatures, health agencies and third-party payers continue to focus on containing the cost of healthcare, including by comparing the effectiveness, benefits and costs of similar treatments. Any adverse findings for our products from such comparisons may reduce the extent of reimbursement for our products. Economic pressure on state budgets may result in states increasingly seeking to achieve budget savings through mechanisms that limit coverage or payment for drugs, including but not limited to price control initiatives, discounts and other pricing-related actions. In November 2021, the U.S. House of Representatives passed the BBBA. The BBBA includes several provisions that may impact our business, including provisions that create an out-of-pocket cap for seniors, impose new manufacturer financial liability (including in Medicare Part D), allow the U.S. government to negotiate prices for some drugs covered under Medicare Part B and Part D, require inflation rebates to limit annual increases in drug prices in Medicare and private insurance, and repeal the rebate rule that would require pass through of pharmacy benefit manager rebates to beneficiaries. While the BBBA has not yet been, and may not in its current form be, signed into law, such provisions, if enacted, could adversely impact our business and financial results.

Over the past several years, a number of states have enacted drug pricing transparency laws that require companies to report on drug price increases and justify how drug prices were set and we expect additional state drug pricing initiatives to be proposed and enacted in the future. In addition, state Medicaid programs are increasingly requesting that manufacturers pay supplemental rebates and requiring prior authorization by the state program for use of any drug. Managed care organizations continue to seek price discounts and, in some cases, to impose restrictions on the coverage of particular drugs. Government efforts to reduce Medicaid expenses may lead to increased use of managed care organizations by Medicaid programs. This may result in managed care organizations influencing prescription decisions for a larger segment of the population and a corresponding constraint on prices and reimbursement for our products.

Furthermore, we may face uncertainties as a result of continued federal and administrative efforts to repeal, substantially modify or invalidate some or all of the provisions of PPACA, the outcome of existing litigation related to PPACA, and potential reforms and changes to government negotiation or regulation of drug pricing. PPACA significantly expanded coverage of mental health and substance use disorders and provided federal parity protections to such coverage benefits. If successful, such efforts and proposed legislation or other future federal or state legislative or administrative changes relating to healthcare reform and drug pricing could

32

Table of Contents

adversely affect our business and financial results.

In addition, the outcome or settlement of litigation could impact the practices of healthcare providers and patients, and the policies and practices of third-party payers, including Medicare, Medicaid, managed care providers and private insurance plans, in a manner detrimental to our products, which in turn could materially and adversely affect our business and financial condition. For example, one or more defendants in the opioid multi-district litigation has offered large volumes of generic buprenorphine free of charge to state plaintiffs as settlement compensation, which, if agreed to and approved, could negatively impact state reimbursement policies, healthcare provider practices, and patient access to alternative FDA-approved medications to generic buprenorphine, which includes VIVITROL, for the treatment of opioid dependence.

In Europe and many other countries, government-sponsored healthcare systems are the primary payers for healthcare expenditures, including payment for drugs and biologics. We expect that countries may take actions to reduce expenditure on drugs and biologics, including mandatory price reductions, patient access restrictions, suspensions of price increases, increased mandatory discounts or rebates, preference for generic products, reduction in the amount of reimbursement and greater importation of drugs from lower-cost countries. Any such cost-control measures would likely reduce our revenues. In addition, certain countries set prices by reference to the prices in other countries where our products are marketed. Thus, the inability to secure adequate prices in a particular country may not only limit the marketing of products within that country, but may also adversely affect the ability to obtain acceptable prices in other markets.

Clinical trials for our products are expensive, may take several years to complete, and their outcomes are uncertain.

In order to obtain regulatory approvals for the commercial sale of any products, we or our licensees must demonstrate, through preclinical testing and clinical trials, that our products are safe and effective for use in humans. Designing, conducting and completing a clinical development program is often a lengthy, time-consuming and expensive process. We have incurred, and we will continue to incur, substantial expenses for preclinical testing, clinical trials and other activities related to our clinical development programs.

Our preclinical and clinical development efforts may take several years or more, varying substantially with the type, complexity, novelty and intended use of the product and the clinical study designs and methodologies employed, and may not be successfully completed in a timely manner or at all. Timelines for the initiation, conduct and completion of clinical trials may be delayed by many factors, including:

In addition, we are currently conducting and enrolling patients in clinical studies in a number of countries where our experience is more limited. In these instances, we must depend on third parties, including independent clinical investigators, CROs and other third-party service providers, to successfully conduct our clinical trials and to audit, verify and accurately report results from such trials. Though we do not have much control over many aspects of such third-party activities, we are responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational plan and protocols for the trial. Third parties may not complete planned activities on schedule or conduct our trials in accordance with regulatory requirements or our stated protocols.

The outcome of our clinical trials is uncertain. The results from preclinical testing and early clinical trials often have not predicted results of later clinical trials. A number of products have shown promising results in early clinical trials but subsequently failed to establish sufficient safety and efficacy data in later clinical trials to obtain necessary regulatory approvals.

If a product fails to demonstrate safety and efficacy in clinical trials, or if third parties fail to conduct clinical trials in accordance with their obligations, the development, approval and commercialization of our products may be delayed or prevented, and such events could materially adversely affect our business, financial condition, cash flows and results of operations.

Table of Contents

Preliminary, topline or interim data from our clinical trials that we may announce, publish or report from time to time may change as more patient data become available or based on subsequent audit and verification procedures, and may not be indicative of final data from such trials, data from future trials or real-world results.

From time to time, we may announce, publish or report preliminary, topline or interim data from our clinical trials, including those we are conducting in oncology. Such data are subject to the risk that one or more of the clinical outcomes may materially change as patients continue progressing through the study (for example, in oncology studies, a patient may progress from a complete or partial response to progressive disease), as patient enrollment continues and/or as more patient data become available, and such data may not be indicative of final data from such trials, data from future trials or real-world results. In addition, such data may remain subject to audit confirmation and verification procedures that may result in the final data being materially different from the preliminary, topline or interim data disclosed. As a result, all preliminary, topline and interim data should be viewed with caution until the final data are available. Material adverse differences between preliminary, topline or interim data and final data could significantly harm our business, financial condition, cash flows and results of operations.

The FDA or other regulatory agencies may not agree with our regulatory approval strategies or components of our filings for our products and may not approve, or may delay approval of, our products.

We must obtain government approvals before marketing or selling our products. The FDA in the U.S., and comparable regulatory agencies in other jurisdictions, impose substantial and rigorous requirements for the development, manufacture and commercialization of medicines, the satisfaction of which can take a significant number of years and can vary substantially based upon the type, complexity and novelty of the product.

In addition, regulation is not static, and regulatory agencies, including the FDA, evolve in their staff, interpretations and practices and may impose more stringent requirements than currently in effect, which may adversely affect our plans for product development, manufacture and/or commercialization. The approval procedure and the time required to obtain approval also varies among countries. Regulatory agencies may have varying interpretations of the same data, and approval by one regulatory agency does not ensure approval by regulatory agencies in other jurisdictions. In addition, the FDA or other regulatory agencies may choose not to communicate with or update us during clinical testing and regulatory review periods and the ultimate decision by the FDA or other regulatory agencies regarding drug approval may not be consistent with prior communications.

The product approval process can last many years, be very costly and still be unsuccessful. Regulatory approval by the FDA or other regulatory agencies can be delayed, limited or not granted at all for many reasons, including:

In addition, disruptions at the FDA and other regulatory agencies that are unrelated to our company or our products, including those relating to COVID-19 or other political or economic conditions, could cause delays to the regulatory approval process for our products. In June 2020, the FDA noted that it was continuing to ensure timely review of applications for medical products during the COVID-19 pandemic in line with its user fee performance goals; however, if a prolonged U.S. government shutdown occurs as a result of political or economic conditions or if the COVID-19 pandemic increases in severity or impact, the FDA’s ability to timely review and process regulatory submissions could be significantly impacted.

Any failure to obtain, or delay in obtaining, regulatory approval for our products will prevent or delay their commercialization and could have a material adverse effect on our business, financial condition, cash flows and results of operations. In addition, any failure to obtain, or delay in obtaining, approval for our products could have a material impact on our shareholders’ confidence in the

34

Table of Contents

strength of our development capabilities and/or our ability to generate significant revenue from our development program and could result in a significant decline in our share price.

The FDA or other regulatory agencies may impose limitations or post-approval requirements on approvals for our products.

Even if regulatory approval to market a product is granted by the FDA or other regulatory agencies, the approved label for the product may not be consistent with our initial expectations or commercial plans. For example, the FDA or other regulatory agencies may impose limitations on the clinical data that may be included in the label for the product or the indicated uses for which, or the manner in which, the product may be marketed, or may impose additional post-approval requirements, such as a REMS, with which we would need to comply in order to maintain the approval of such product. Our business could be seriously harmed if we do not complete these post-approval requirements and, as a result, the FDA or other regulatory agencies require us to change the label for such product, or if such post-approval requirements significantly restrict the marketing, sale or use of such product.

Further, if a product for which we obtain regulatory approval is a controlled substance, it will not become commercially available until after the DEA provides its final schedule designation for the product, which may take longer and may be more restrictive than we expect or may change after its initial designation. In addition, a final designation that is more restrictive than we expect could adversely affect our ability to commercialize such product and could materially adversely affect our business, financial condition, cash flows and results of operations.

In addition, legislation and regulatory policies relating to post-approval requirements and restrictions on promotional activities for pharmaceutical products, or FDA, DEA or other regulatory agency regulations, guidance or interpretations with respect to such legislation or regulatory policy, may change, which may impact the development and commercialization of our products.

We are subject to risks related to the manufacture of our products.

The manufacture of pharmaceutical products is a highly complex process in which a variety of difficulties may arise from time to time. We have in the past, and may in the future, face unanticipated interruptions or delays in manufacturing through our internal or external supply chain and resources. Such disruptions can occur for many reasons, including, but not limited to, the supply and quality of API, drug product and other product components and any potential shortages of such materials; regulatory actions; failures relating to materials, manufacturing equipment or processes, quality deviations or safety issues, vendor error, operator error, labor shortages or disputes, utility or transportation disruptions, or physical or electronic security breaches; site-specific incidents (such as fires), environmental incidents, natural disasters and other severe weather events, including those that may occur as a result of climate change , or global disruptions such as the current global pandemic; and many other factors.

Any such problems with manufacturing processes, whether at our facilities or those of our licensees or other third parties that manufacture or package products or components of products on our behalf, could result in product defects or shortages, manufacturing failures or products not being manufactured to their applicable specifications, which could require us to delay shipment of products or recall products previously shipped, or could impair our ability to receive regulatory approval for a product, commercially launch a product, expand into new markets or supply products in existing markets. We may not be able to resolve any such issues in a timely manner, or at all, which could result in declines in sales and reputational damage as well as significant remediation costs to address any issues that arise.

We rely solely on our manufacturing facility in Wilmington, Ohio for the manufacture of RISPERDAL CONSTA, VIVITROL, ARISTADA, ARISTADA INITIO and LYBALVI and on our manufacturing facility in Athlone, Ireland for the manufacture of AMPYRA, FAMPYRA, VUMERITY, other products using our NanoCrystal or OCR technologies and certain of our other products in development. Due to regulatory and technical requirements, we have limited ability to shift production among our facilities or to outsource any portions of our manufacturing to third parties in the event of an interruption in manufacturing or demand for manufacturing that exceeds our capacity at the applicable facility. Any need to shift production among our facilities or transition our manufacturing processes, or portions thereof, to a third party, whether due to an interruption in our manufacturing or to demand for a product that exceeds our manufacturing capacity, could take a significant amount of time and money, may not be successful, and could cause significant delay in our ability to supply product.

Any interruption in supply, whether resulting from issues with equipment, materials, personnel, manufacturing processes, or internal or external quality audits or reviews, could result in delays in meeting our contractual obligations and could damage our relationships with our licensees, including the loss of manufacturing and supply rights and/or revenues.

Our manufacturing facilities also require specialized personnel and are expensive to operate and maintain. Any interruption in manufacturing, delay in a regulatory approval or commercial launch, or recall or suspension of sales of products manufactured in our facilities, may cause operating losses as we continue to operate these facilities and retain the required specialized personnel. In addition, any significant personnel shortages at our manufacturing facilities, whether temporary or prolonged, including shortages resulting from impacts of the COVID-19 pandemic and related mandates, testing protocols or restrictions, or shortages related to the labor market more broadly, may cause significant interruptions to our manufacturing facilities and to our supply of products.

We are also dependent in certain cases on third parties who manufacture or distribute certain products from which we receive revenue. Supply or manufacturing issues related to such products could materially and adversely affect sales of such products, and in

35

Table of Contents

turn our revenue from such products.

We rely on third parties to provide goods and services in connection with the manufacture and distribution of the products we manufacture.

We rely on third parties for the timely supply of goods and services that play a role in our manufacturing activities, including, among others, specified raw materials, equipment, contract manufacturing, formulation and packaging services, storage and product distribution services, customer service activities and product returns processing, and some of these goods and services for our products are currently only available from a single source or a limited number of qualified sources. Although we actively manage these third-party relationships to ensure continuity, quality and compliance with applicable regulations, events beyond our control could result in the complete or partial failure of these goods and services. Any such failure could materially adversely affect our business, financial condition, cash flows and results of operations.

The manufacture of products and product components, including the procurement of bulk drug product and other materials used in the manufacture, packaging, storage and distribution of our products, requires successful coordination among us and multiple third-party providers. Lack of capacity available at such third-party providers or any other issues with the quality or operations of these third-party providers, including any issues related to regulatory permits, audits or requirements, could require us to delay shipment of saleable products, recall products previously shipped or impair our ability to supply products at all.

We endeavor to qualify and register new vendors and to develop contingency plans so that production is not materially impacted by third-party provider issues. Nonetheless, any such third-party provider issues could increase our costs, cause us to lose revenue or market share and damage our reputation, and may have a material adverse effect on our business, financial condition, cash flows and results of operations.

In addition, we rely heavily on the three largest pharmaceutical wholesalers in the U.S. market—Cardinal Health Inc., AmerisourceBergen Corp. and McKesson Corp—in the distribution of the products that we market and sell in the U.S. If we are unable to maintain our business relationships with these wholesalers on commercially acceptable terms, if the buying patterns of these wholesalers fluctuate due to seasonality or any other reason or if wholesaler buying decisions or other factors outside of our control change, our business, financial condition, cash flows and results of operations could be materially adversely affected.

If we or our third-party providers fail to meet the stringent requirements of governmental regulation in the manufacture of our products, we could incur substantial remedial costs and a reduction in sales and/or revenues.

We and the third-party providers that play a role in our manufacturing activities are generally required to comply with cGMP regulations and other applicable non-U.S. standards in the manufacture of our products or components of our products. In addition, in the U.S., the DEA and state-level agencies heavily regulate the manufacturing, holding, processing, security, recordkeeping and distribution of substances, including controlled substances. If any of our products or components of our products are scheduled by the DEA as controlled substances, we would be subject to such DEA regulations. We and our third-party providers are subject to unannounced inspections by the FDA, the DEA and comparable U.S. state and non-U.S. agencies in other jurisdictions to confirm compliance with all applicable laws. Any changes to our suppliers or modifications of methods of manufacturing require submission of amendments to our NDAs or other marketing applications to the FDA or other applicable regulatory agencies, and ultimate acceptance by such agencies of such amendments, prior to release of product to the applicable marketplace. Our inability or the inability of our third-party providers to demonstrate ongoing compliance with cGMP or other regulatory requirements could require us to withdraw or recall products and interrupt clinical and commercial supply of our products. Any delay, interruption or other issues that may arise in the manufacture, formulation, packaging or storage of our products as a result of a failure of our facilities or operations or the facilities or operations of third-party providers to pass any regulatory agency inspection could significantly impair our ability to develop, obtain and maintain regulatory approval of, and commercialize or supply, products. This could increase our costs, cause us to lose revenue or market share and damage our reputation with our collaboration partners or in the market generally.

In March 2020, in response to the COVID-19 pandemic, the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act was signed into law in the U.S., and served to increase the FDA’s existing authority with respect to drug shortage measures. Under the CARES Act, for each facility where marketed products for certain serious diseases or conditions are manufactured, or where components of such products are manufactured, we are required to have a risk management plan in place that identifies and evaluates risks to the supply of such products or product components, which plans may be subject to review during any FDA inspection. Each of our facilities operates in accordance with a comprehensive quality management system, which includes risk assessment, preventive actions and regular review of inventory levels for each of the marketed products that we manufacture; however, there is no guarantee that the FDA will consider our risk management program to be sufficient upon inspection or that we will not experience shortages in the supply of marketed products that we manufacture, which could materially adversely affect the patients who rely on such marketed products and our business, financial condition, cash flows and results of operations. The FDA and various regulatory agencies outside the U.S. have inspected and approved our commercial manufacturing facilities. However, we cannot guarantee that the FDA or any other regulatory agencies will approve any other facility that we or our third-party providers may operate or, once approved, that any of these facilities will remain in compliance with cGMP and other regulations. Any third party we use to manufacture bulk drug product for use in the U.S. must be licensed by the FDA and, for controlled substances, the DEA. Failure by us or our third-party

providers to gain or maintain regulatory compliance with and approvals from the FDA or other regulatory agencies could materially adversely affect our business, financial condition, cash flows and results of operations.

Adverse market conditions may exacerbate certain risks inherent to our business, including risk of payment from licensees and customers and reimbursement for our products.

Adverse market conditions may cause disruptions or delays to our business or to the businesses of third parties from whom we receive revenues, or reductions in the availability or extent of reimbursement available to us. For example, we depend on our licensees and customers for substantial portions of our revenue, and the contracts with our licensees and customers pursuant to which we supply product, or under which we are eligible for certain development or sales milestones or royalties related to products that incorporate our proprietary technologies, may not be secured by collateral or other security. Accordingly, we bear the risk that our licensees may not be able to pay amounts due to us under such contracts.

In addition, as a result of adverse market conditions, organizations that provide reimbursement for use of our products, such as government health administration authorities and private health insurers, may be unable to satisfy such reimbursement obligations or may delay payment. In addition, U.S. federal and state health authorities may reduce the extent of their reimbursements (including Medicare and Medicaid reimbursements in the U.S.) or payments, and private insurers may increase their scrutiny of claims. If such licensees or other third parties are unable or unwilling to pay amounts owed to us or satisfy their commitments to us, or if there are reductions to such payments or commitments, our business, financial condition, cash flows and results of operations may be materially adversely affected.

Our success largely depends upon our ability to attract, recognize and retain key personnel.

Our ability to compete and succeed in the highly competitive biopharmaceutical industry and in the disease states in which we market and sell products depends largely upon our ability to attract, recognize and retain highly skilled technical, scientific, manufacturing, management, regulatory, compliance and selling and marketing personnel. Each of our executive officers and all of our employees are employed “at will,” meaning we or each officer or employee may terminate the employment relationship at any time. We face intense competition for employees, due, among many factors, to the geographic locations in which we operate and the competitive benefits and compensation practices in our industry, and in recent years, new competition as employees are increasingly able to work remotely. Government vaccine or masking mandates, testing protocols, or other restrictions that apply to us may have an impact on employee performance, retention and recruitment, particularly for those employees who perform essential tasks in our laboratories and manufacturing facilities and cannot perform their jobs remotely. The loss of key personnel due to any of these factors or our inability to hire and retain personnel who have technical, scientific, manufacturing, management, regulatory, compliance or commercial backgrounds could materially adversely impact our business, including the achievement of our manufacturing, research and development, commercial, financial and other operational and strategic business objectives.

The increasing use of social media platforms presents new risks and challenges.

Social media is increasingly being used as a means of corporate communications and for purposes of social networking and commentary. We are increasingly using social media tools to communicate certain information about our business, our employees, our company values and corporate responsibility initiatives, to support disease state education in our areas of focus, and to provide information about our products or development programs. Despite our efforts to monitor evolving social media guidance and to comply with applicable rules, regulations and regulatory guidance relating to social media, such practices are evolving and not always clear. There is a risk that the use of social media by us or our employees to communicate about our products or business may cause us to be found in violation of applicable requirements and could result in regulatory actions or legal claims against us related to off-label marketing or other prohibited activities. In addition, our employees may knowingly or inadvertently engage on social media in ways that may not comply with our social media policy or other legal, contractual or regulatory requirements, which may give rise to liability, lead to the loss of trade secrets and other intellectual property, or result in public disclosure of personal information of our employees, clinical trial patients, customers, and others. In addition, negative or inaccurate posts or comments about us or our products on any social media platforms could damage our reputation, brand image and goodwill. If such disclosures were to occur, there is a risk that we fail to monitor and comply with applicable adverse event reporting obligations or that we may not be able to defend the Company or the public’s legitimate interests due to restrictions on what we may say about our products or our business. Any of these events, if they were to occur, could cause us to incur liability, face overly restrictive regulatory actions or suffer reputational or other harm to our business

Risks Related to Intellectual Property

Patent and other IP protection for our products is key to our business and our competitive position but is uncertain.

Receiving and maintaining patent and/or trademark protection for our products and technologies, including those that are subject to our licensing arrangements, maintaining our trade secrets, not infringing the proprietary rights of others, and preventing others from infringing our proprietary rights are each key to our success and our competitive position.

Patent protection provides rights of exclusivity for the term of the patent. We are able to protect our proprietary rights from

37

Table of Contents

unauthorized use by third parties only to the extent that our proprietary rights are covered by valid and enforceable patents or are effectively maintained as trade secrets. In this regard, we try to protect our proprietary position by filing patent applications in the U.S. and elsewhere related to our proprietary product inventions and improvements that are important to our business and products. Our pending patent applications, together with those we may file in the future, or those we may license to or from third parties, may not result in patents being issued. Even if issued, such patents may not provide us with sufficient proprietary protection or competitive advantages against competitors with similar products or technology. Because the patent positions of biopharmaceutical companies involve complex legal and factual questions, enforceability of patents cannot be predicted with certainty. The ultimate degree of patent protection that will be afforded to products and processes, including ours, and those of our licensees, in the U.S. and in other important markets, remains uncertain and is dependent upon the scope of protection decided upon by the patent offices, courts and lawmakers in these countries. The development of new technologies or products may take a number of years, and there can be no assurance that any patents which may be granted in respect of such technologies or products will not have expired or be due to expire by the time such products are commercialized, or that such patents will successfully withstand any challenges during their respective terms.

Although we make reasonable efforts to protect our IP rights and to ensure that our proprietary technology does not infringe the rights of third parties, we cannot ascertain the existence of all potentially conflicting IP claims. Therefore, there is a risk that third parties may make claims of infringement against our products or technologies. If patents exist or are issued that cover our products or technologies, we may not be able to manufacture, use, offer for sale, sell or import such products without first getting a license from the patent holder. The patent holder may not grant us a license on reasonable terms, or it may refuse to grant us a license at all. This could delay or prevent us from developing, manufacturing, selling or importing those of our products that would require the license. Claims of IP infringement may also require that we redesign affected products, enter into costly settlement or license agreements, pay costly damage awards, or face a temporary or permanent injunction prohibiting us from marketing or selling certain of our products. Even if we have an agreement that may serve to indemnify us against such costs, the indemnifying party may be unable to uphold its contractual obligations. If we cannot, or do not, license the infringed technology on reasonable terms or at all, or substitute similar technology from another source, our business, financial condition, cash flows and results of operations could be materially adversely affected.

Patents, if issued, may be challenged, invalidated or circumvented. As our products achieve greater commercial sales, potential competitors are more likely to seek to challenge our patents. The laws of certain countries may not protect our IP rights to the same extent as the laws of the U.S., and any patents that we own or license from others may not provide any protection against competitors. In addition, in the case of certain of our licensed products or products incorporating our licensed technology, our licensees are responsible for prosecuting, maintaining, enforcing and defending the IP related to the product(s) from which we derive revenue. Their failure to secure, maintain, enforce and defend this IP could materially and adversely affect our business, financial condition, cash flows, and results of operations.

We also rely on trade secrets, know-how and inventions, which are not protected by patents, to maintain our competitive position. We try to protect this information by entering into confidentiality agreements with parties that have access to it, such as our licensees, licensors, contract manufacturers, potential business partners, employees and consultants. However, any of these parties may breach such agreements and may disclose our confidential information, or our competitors might learn of the information in some other way. To the extent that our employees, consultants or contractors use IP owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions. If any trade secret, know-how or other invention not protected by a patent were to be disclosed to, or independently developed by, a competitor, such event could materially and adversely affect our business, financial condition, cash flows and results of operations.

Uncertainty over IP in the biopharmaceutical industry has been the source of litigation, which is inherently costly and unpredictable, could significantly delay or prevent approval or negatively impact commercialization of our products, and could adversely affect our business.

There is considerable uncertainty within the biopharmaceutical industry about the validity, scope and enforceability of many issued patents in the U.S. and elsewhere in the world. We cannot currently determine the ultimate scope, validity and enforceability of patents which may be granted to third parties in the future or which patents third parties may assert are infringed by the manufacture, use or sale of our products.

Stemming in part from this uncertainty, there has been, and we expect that there may continue to be, significant litigation and an increasing number of inter partes reviews (“IPRs”) and administrative proceedings in the pharmaceutical industry regarding patents and other IP rights. A patent holder might file an IPR, interference and/or infringement action against us, including in response to patent certifications required under the Hatch-Waxman Act, claiming that certain claims of one or more of our issued patents are invalid or that the manufacture, use, offer for sale, sale or import of our products infringed one or more of such party’s patents. We may have to expend considerable time, effort and resources to defend such actions, and litigation may be necessary in some instances to determine the validity and scope of certain of our proprietary rights.

In addition, we may need to enforce our IP rights against third parties who infringe our patents and other IP or challenge our patents, patent applications or trademark applications. Litigation and trial proceedings, such as so-called Paragraph IV litigation and IPRs, concerning patents and other IP rights may be expensive, protracted and distracting to management, with no certainty of

38

Table of Contents

success. As a result, we may at times give up certain rights with respect to our IP in order to avoid or resolve timely and costly IP litigation or IPR proceedings. For example, in July 2019, in order to resolve an IPR instituted by Amneal with the PTAB, we granted Amneal a non-exclusive license under certain patents covering VIVITROL, including the latest to expire patent covering VIVITROL in the U.S., to market and sell a generic formulation of VIVITROL in the U.S. beginning sometime in 2028 or earlier under certain circumstances. Ultimately, the outcome of such litigation and proceedings, or any settlement arrangement with respect thereto, could adversely affect our business and the validity and scope of our patents or other proprietary rights or delay or prevent us from manufacturing and marketing our products.

We or our licensees may face claims against IP rights covering our products and competition from generic drug manufacturers.

In the U.S., generic manufacturers of innovator drug products may file ANDAs and, in connection with such filings, certify that their products do not infringe the innovator’s patents or that the innovator’s patents are invalid. This often results in litigation between the innovator and the ANDA applicant. This type of litigation is commonly known in the U.S. as “Paragraph IV” litigation.

For example, Teva entities filed an ANDA seeking approval to engage in the commercial manufacture, use or sale of a generic version of VIVITROL and alleging that one of our Orange-Book patents related to VIVITROL is invalid, unenforceable and/or will not be infringed by Teva’s proposed product. In September 2020, we initiated a Paragraph IV lawsuit against Teva to dispute such claims.

Although we intend to vigorously defend our IP rights, and we expect our licensees to do the same, there can be no assurance that we or our licensees will prevail. Our and our licensees’ existing patents could be invalidated, found unenforceable or found not to cover generic forms of our or our licensees’ products. If Teva or other ANDA filers were to receive FDA approval to sell generic versions of our products or the products from which we receive revenue and/or prevail in any patent litigation with respect to such products, such products would become subject to increased competition, and our business, financial condition, cash flows and results of operations could be materially adversely affected.

Risks Related to Regulatory or Legal Matters

Litigation or arbitration filed against Alkermes, including securities litigation, or actions (such as citizens petitions) filed against regulatory agencies in respect of our products, may result in financial losses, harm our reputation, divert management resources, negatively impact the approval of our products, or otherwise negatively impact our business.

We are, and may in the future become, involved in various legal proceedings, including those asserting violations of securities and/or fraud and abuse laws and those asserting claims related to product liability, intellectual property and/or contractual arrangements. Such proceedings may include claims for, or the possibility of, damages or fines and penalties involving substantial amounts of money or other relief, including but not limited to civil or criminal fines and penalties. Such legal proceedings and the preparation therefor may result in substantial costs to us and diversion of management’s attention and resources, which in turn could harm our business. Moreover, if any of such legal proceedings were to result in an adverse outcome, such outcome could have a material adverse effect on our business, financial condition, cash flows and results of operations.

We have been, and may continue to be, the subject of certain government inquiries or requests for documentation. For example, we have received a subpoena and civil investigative demands from U.S. state and federal authorities for documents related to VIVITROL. We are cooperating with the government in each instance. If, as a result of government requests, proceedings are initiated, including under the U.S. federal anti-kickback statute and False Claims Act and state False Claims Acts or other laws, and we are found to have violated one or more applicable laws, we may be subject to significant liability, including without limitation, civil fines, criminal fines and penalties, civil damages and exclusion from U.S. federal funded healthcare programs such as Medicare and Medicaid, and may be required to enter into a corporate integrity or other settlement with the government, any of which could materially affect our reputation, business, financial condition, cash flows and results of operations. Conduct giving rise to such liability could also form the basis for private civil litigation by third-party payers or other persons allegedly harmed by such conduct. In addition, if any of our existing business practices, including those of our sales force, are challenged as unlawful, we may have to change those practices, which could have a material adverse effect on our business, financial condition, cash flows and results of operations.

Further, our liability insurance coverage may not be sufficient to satisfy, or may not cover, any expenses or liabilities that may arise. Additionally, regardless of whether or not there is merit to the claims underlying any lawsuits or government inquiries of which we are subject, or whether or not we are found as a result of such lawsuits or inquiries to have violated any applicable laws, such lawsuits and inquiries can be expensive to defend or respond to, may divert the attention of our management and other resources that would otherwise be engaged in managing our business, and may further cause significant and potentially irreparable harm to our public reputation.

We have been, and may again be, the subject of citizen petitions that request that the FDA refuse to approve, delay approval of, or impose additional approval requirements on our NDAs. If successful, such petitions can significantly delay, or even prevent, the approval of the NDA in question. Even if the FDA ultimately denies such a petition, the FDA may substantially delay approval while

39

Table of Contents

it considers and responds to the petition, or may impose additional approval requirements as a result of such petition. These outcomes and others could adversely affect our share price as well as our ability to generate revenues from the commercialization and sale of our products and products using our proprietary technologies.

The clinical study or commercial use of our products may cause unintended side effects or adverse reactions, or incidents of misuse may occur, which could adversely affect our products, business and share price.

We cannot predict whether the clinical or commercial use of our products will produce undesirable or unintended side effects that have not been evident in the use of, or in clinical trials conducted for, such products to date. The administration of drugs in humans carries the inherent risk of product liability claims whether or not the drugs are actually the cause of an injury. Our products may cause, or may appear to have caused, injury or dangerous drug interactions, and we may not learn about or understand those effects until the products have been administered to study participants or patients for a prolonged period of time. Additionally, incidents of product misuse may occur.

These events, among others, could result in product recalls or additional regulatory controls (including additional regulatory scrutiny, REMS programs, and requirements for additional labeling) or product liability actions. As our development activities progress and we continue to have commercial sales, our product liability insurance coverage may be inadequate to satisfy liabilities that arise, we may be unable to obtain adequate coverage at an acceptable cost or at all, or our insurer may disclaim coverage as to a future claim. This could prevent or limit the development or commercialization of our products. In addition, the reporting of adverse safety events involving our products, including instances of product misuse, and public rumors about such events could cause our product sales or share price to decline or experience periods of volatility. These types of events could have a material adverse effect on our business, financial condition, cash flows and results of operations.

If there are changes in, or we fail to comply with, the extensive legal and regulatory requirements affecting the healthcare industry, we could face costs, penalties and business losses.

Our activities, and the activities of our licensees and third-party providers, are subject to extensive government regulation. Government regulation by various national, state and local agencies includes detailed inspections of, and controls over, research and laboratory procedures, clinical investigations, product approvals and manufacturing, marketing and promotion, adverse event reporting, sampling, distribution, recordkeeping, storage, and disposal practices. Achieving compliance with these regulations substantially increases the time, difficulty and costs incurred in obtaining and maintaining approvals to market newly developed and existing products. Government regulatory actions, including audits, records requests and inspections of manufacturing facilities, can result in delay in the release of products, seizure or recall of products, suspension or revocation of the authority necessary for the manufacture and sale of products, and other regulatory enforcement actions, including the levying of civil fines or criminal penalties, the issuance of a warning letter, or the imposition of an injunction. Biopharmaceutical companies also have been the target of government lawsuits and investigations alleging violations of government regulation, including claims asserting submission of incorrect pricing information, impermissible off-label promotion of pharmaceutical products, payments intended to influence the referral of healthcare business, submission of false claims for government reimbursement, antitrust violations and violations related to environmental matters.

While we have implemented numerous risk mitigation measures, we cannot guarantee that we, our employees, our licensees, our consultants or our contractors are, or will be, in compliance with all applicable laws, regulations or interpretations of the applicability of these laws to our products, operations and marketing practices. If we or our agents fail to comply with any of those laws, regulations or interpretations, a range of actions could result, including the suspension or termination of clinical trials, the failure to approve a product, restrictions on sales of our products or our manufacturing processes, withdrawal of our products from the market, significant fines, exclusion from government healthcare programs or other sanctions or litigation.

Changes affecting the healthcare industry, including new laws, regulations or judicial decisions, or new interpretations of existing laws, regulations or decisions, related to patent protection and enforcement, access to healthcare, environmental issues or product pricing and marketing, could also adversely affect our revenues, our public reputation or our potential to be profitable. For example, the costs of prescription pharmaceuticals in the U.S. have been the subject of considerable discussion in the U.S. and the government may seek to address such costs through new legislative and/or administrative measures. Such changes in laws, regulations or decisions or in the interpretation of existing laws, regulations and decisions could have a material adverse effect on our business, financial condition, cash flows and results of operations.

Our business involves environmental, health and safety risks.

Our business involves the use of hazardous materials and chemicals and is subject to numerous environmental, health and safety laws and regulations and to periodic inspections for possible violations of these laws and regulations. Under certain of these laws and regulations, we could be liable for any contamination at our current or former properties or third-party waste disposal sites. In addition to significant remediation costs, contamination can give rise to third-party claims for fines, penalties, natural resource damages, personal injury and damage (including property damage). The costs of compliance with environmental, health and safety laws and

40

Table of Contents

regulations are significant. We have developed and implemented a proprietary risk mitigation program to preemptively identify and address environmental, health, safety and security risks; however, there can be no assurance that a violation of current or future environmental, health or safety laws or regulations will not occur. Any violations, even if inadvertent or accidental, or the cost of compliance with any resulting order, fine or liability that may be imposed, could materially adversely affect our business, financial condition, cash flows and results of operations.

Risks Related to our Financial Condition and Tax Matters

We may not become profitable on a sustained basis.

At December 31, 2021, our accumulated deficit was $1.5 billion, which was primarily the result of net losses incurred from 1987, the year Alkermes, Inc., was founded, through December 31, 2021, partially offset by net income over certain fiscal periods.

Our ability to achieve sustained profitability in the future will depend on our ability to grow and diversify our revenue and effectively and efficiently manage our costs. Factors that may impact our future revenue, and in turn our future profitability, include our or our licensees’ (as applicable) ability to:

Factors that may impact our future spend, and in turn our future profitability, include:

Certain U.S. holders of our ordinary shares may suffer adverse tax consequences if any of our non-U.S. subsidiaries are characterized as a “controlled foreign corporation”.

In December 2017, the Tax Cuts and Jobs Act was signed into law. This legislation significantly changed U.S. tax law by, among other things, changing the rules which determine whether a foreign corporation is treated for U.S. tax purposes as a controlled foreign corporation (“CFC”) for taxable years ended December 31, 2017 and onwards. The impact of this change on certain holders of our ordinary shares is uncertain and could be adverse, including potential income inclusions and reporting requirements for U.S. persons (as defined in the Internal Revenue Code) who are treated as owning (directly or indirectly) at least 10% of the value or voting power of our shares. The determination of CFC status is complex and includes attribution rules, the application of which are not entirely certain. These changes to the attribution rules relating to the determination of CFC status make it possible that one or more of our non-U.S. subsidiaries will be classified as a CFC. Existing and prospective investors should consult their tax advisers regarding the potential application of these rules to their investments in us.

Table of Contents

See “Certain Irish and United States Federal Income Tax Considerations – United States Federal Income Tax Considerations” in our Form S-1/A, filed with the SEC on February 29, 2012, for additional discussion with respect to other potential U.S. federal income tax consequences of investments in us.

If goodwill or other intangible assets become impaired, we could have to take significant charges against earnings.

At December 31, 2021, we had $74.0 million of amortizable intangible assets and $92.9 million of goodwill. Under accounting principles generally accepted in the U.S. (“GAAP”), we must assess, at least annually and potentially more frequently, whether the value of goodwill and other indefinite‑lived intangible assets have been impaired. Amortizing intangible assets will be assessed for impairment in the event of an impairment indicator. Any reduction or impairment of the value of goodwill or other intangible assets will result in a charge against earnings, which could materially adversely affect our results of operations and shareholders’ equity in future periods.

Our effective tax rate may increase.

As a global biopharmaceutical company, we are subject to taxation in a number of different jurisdictions. As a result, our effective tax rate is derived from a combination of applicable tax rates in the various places that we operate. In preparing our financial statements, we estimate the amount of tax that will become payable in each of these places. Our effective tax rate may fluctuate depending on a number of factors, including, but not limited to, the distribution of our profits or losses between the jurisdictions where we operate and differences in interpretation of tax laws. In addition, the tax laws of any jurisdiction in which we operate may change in the future, which could impact our effective tax rate. Tax authorities in the jurisdictions in which we operate may audit us. If we are unsuccessful in defending any tax positions adopted in our submitted tax returns, we may be required to pay taxes for prior periods, interest, fines or penalties, and may be obligated to pay increased taxes in the future, any of which could have a material adverse effect on our business, financial condition, cash flows and results of operations.

Changes in tax rules and regulations, or interpretations thereof, may adversely affect our financial condition.

Effective January 1, 2022, the Tax Cuts and Jobs Act of 2017 eliminated the option to deduct R&D expenses in the year incurred and instead requires taxpayers to capitalize, and subsequently amortize such expenses over five years for research activities conducted in the U.S. and over fifteen years for research activities conducted outside of the U.S. As such, we expect a material decrease in cash flows provided from operations and a material increase in our net deferred tax assets over these amortization periods.  The actual impact of this change will depend on multiple factors, including the amount of R&D expenses incurred and whether the research activities are performed within or outside of the U.S. 

Unless the U.S. Department of the Treasury issues regulations that narrow the application of this provision to a smaller subset of our R&D expenses or the provision is deferred, modified or repealed by the U.S. Congress, there will be a material increase in our U.S. income tax liability over these amortization periods.  

Our deferred tax assets may not be realized.

As of December 31, 2021, we had $81.8 million of net deferred tax assets in the U.S. Included in this amount was approximately $1.7 million of U.S. federal net operating loss (“NOL”) carryforwards and $38.5 million of research and development tax credit carryforwards that can be used to reduce U.S. taxable income or offset federal tax in future periods. These carryforwards will expire within the next twenty years. It is possible that some or all of the deferred tax assets will not be realized, especially if we incur losses in the U.S. in the future. Losses may arise from unforeseen operating events, an enlarged foreign derived intangible income deduction due to the capitalization of R&D expenses, or the occurrence of significant excess tax benefits arising from the exercise of stock options and/or the vesting of restricted stock units. Unless we are able to generate sufficient taxable income in the future, a substantial valuation allowance to reduce the carrying value of our U.S. deferred tax assets may be required, which would materially increase our expenses in the period the valuation allowance is recognized and materially adversely affect our business, financial condition and results of operations.

Furthermore, we have included within our U.S. net deferred tax assets of $81.8 million an amount of $36.1 million relating to employee share-based compensation expense. It is possible that a material portion of this deferred tax asset will not be realized, especially if the price of our ordinary shares remains at its current level (refer to “Item 5—Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities” in this Annual Report for details of the price of our ordinary shares). Unless the price of our ordinary shares increases, we will incur a deferred tax expense as our U.S.-based employees exercise or forfeit their stock options and their restricted stock unit awards vest. This could materially increase our tax expense and may materially adversely affect our financial condition and results of operations.

The business combination in 2011 of Alkermes, Inc. and the drug technology business (“EDT”) of Elan Corporation, plc may limit our ability to use our tax attributes to offset taxable income, if any, generated from such business combination.

42

Table of Contents

On September 16, 2011, the businesses of Alkermes, Inc. and EDT were combined under Alkermes plc (this combination is referred to as the “Business Combination”). For U.S. federal income tax purposes, a corporation is generally considered tax resident in the place of its incorporation. Because we are incorporated in Ireland, we should be deemed an Irish corporation under these general rules. However, Section 7874 of the Internal Revenue Code of 1986, as amended (the “Code”) generally provides that a corporation organized outside the U.S. that acquires substantially all of the assets of a corporation organized in the U.S. will be treated as a U.S. corporation (and, therefore, a U.S. tax resident) for U.S. federal income tax purposes if shareholders of the acquired U.S. corporation own at least 80% (of either the voting power or the value) of the stock of the acquiring foreign corporation after the acquisition by reason of holding stock in the domestic corporation, and the “expanded affiliated group” (as defined in Section 7874) that includes the acquiring corporation does not have substantial business activities in the country in which it is organized.

In addition, Section 7874 provides that if a corporation organized outside the U.S. acquires substantially all of the assets of a corporation organized in the U.S., the taxable income of the U.S. corporation during the period beginning on the date the first assets are acquired as part of the acquisition, through the date which is ten years after the last date assets are acquired as part of the acquisition, shall be no less than the income or gain recognized by reason of the transfer during such period or by reason of a license of property by the expatriated entity after such acquisition to a foreign affiliate during such period, which is referred to as the “inversion gain,” if shareholders of the acquired U.S. corporation own at least 60% (of either the voting power or the value) of the stock of the acquiring foreign corporation after the acquisition by reason of holding stock in the domestic corporation, and the “expanded affiliated group” of the acquiring corporation does not have substantial business activities in the country in which it is organized. If this rule was to apply to the Business Combination, among other things, Alkermes, Inc. would have been restricted in its ability to use the approximately $274.0 million of U.S. federal NOL carryforwards and $38.0 million of U.S. state NOL carryforwards that it had as of March 31, 2011. We do not believe that either of these limitations should apply as a result of the Business Combination. However, the U.S. Internal Revenue Service (the “IRS”) could assert a contrary position, in which case we could become involved in tax controversy with the IRS regarding possible additional U.S. tax liability. If we were to be unsuccessful in resolving any such tax controversy in our favor, we could be liable for significantly greater U.S. federal and state income tax than we anticipate being liable for through the Business Combination, which would place further demands on our cash needs.

Our level of indebtedness could adversely affect our business and limit our ability to plan for or respond to changes in our business.

In March 2021, we amended and refinanced our existing term loan (the “2023 Term Loans”), in order to, among other things, provide for a new class of replacement term loans equal to $300.0 million; extend the due date of the loan from March 26, 2023 to March 12, 2026; amend the interest payable from LIBOR plus 2.25% with no LIBOR floor to LIBOR plus 2.50% with a LIBOR floor of 0.5%; and increase covenant flexibility (such refinancing, the “Term Loan Refinancing” and the 2023 Term Loans as so amended and refinanced the “2026 Term Loans”). The 2026 Term Loans were also amended to include customary Alternative Reference Rates Committee (“ARRC”) hardwired benchmark replacement language. As of December 31, 2021, our borrowings consisted of $295.8 million outstanding under the 2026 Term Loans.

The 2026 Term Loans are secured by a first priority lien on substantially all of the combined company assets and properties of Alkermes plc and most of its subsidiaries, which serve as guarantors. The agreements governing the 2026 Term Loans include a number of restrictive covenants that, among other things, and subject to certain exceptions and baskets, impose operating and financial restrictions on us.

Our failure to comply with these restrictions or to make these payments could lead to an event of default that could result in an acceleration of the indebtedness. Our future operating results may not be sufficient to ensure our ability to make our debt payments or to remedy any such default. In the event of an acceleration of this indebtedness, we may not have, or be able to obtain, sufficient funds to make any accelerated payments.

Discontinuation, reform or replacement of LIBOR, or uncertainty related to the potential for any of the foregoing, may adversely affect us.

In 2017, the U.K. Financial Conduct Authority announced its intention to phase out LIBOR after 2023. Currently, it is anticipated that LIBOR will be completely phased out by June 30, 2023. The U.S. Federal Reserve, in conjunction with the ARRC, a steering committee comprised of large U.S. financial institutions, has proposed a new index calculated by short term repurchase agreements, backed by U.S. Treasury securities, called the Secured Overnight Financing Rate (“SOFR”) as an alternative to LIBOR for use in contracts that are currently indexed to U.S. dollar LIBOR and has proposed a paced market transition plan to SOFR. On July 29, 2021, the ARRC formally recommended SOFR as its preferred alternative replacement rate for U.S. dollar LIBOR. The 2026 Term Loans contain customary ARRC hardwired benchmark replacement language to transition from LIBOR to SOFR. The discontinuation, reform or replacement of LIBOR or any other benchmark rates may have an unpredictable impact on contractual mechanics in the credit markets or cause disruption to the broader financial markets. Uncertainty as to the nature of such potential discontinuation, reform or replacement may negatively impact the volatility of LIBOR rates, liquidity, or our access to funding required to operate our business.

Our business strategy may involve future transactions which may harm the market price of our ordinary shares or require us to seek additional funds, and such funding may not be available on commercially favorable terms or at all and may cause dilution to our existing shareholders.

In order to achieve our business strategy, we regularly review potential transactions related to technologies, products or product rights, and businesses that are complementary to our business, including mergers and acquisitions, licenses and collaborations, and development and supply, commercialization or co-promotion arrangements, among others. We may choose to enter into one or more of these or other transactions at any time, which may cause substantial fluctuations in the market price of our ordinary shares. Moreover, depending upon the nature of any transaction, we may experience a charge to earnings, which could also materially adversely affect our results of operations and could harm the market price of our ordinary shares.

In order to finance such transactions, we may require additional funds, and we may seek such funds through various sources, including debt and equity offerings, corporate collaborations, bank borrowings, arrangements relating to assets, monetization of royalty streams or other financing methods or structures. The source, timing and availability of any financings will depend on global economic conditions, credit and financial market conditions, interest rates and other factors. If we issue additional equity securities or securities convertible into equity securities, our shareholders will suffer dilution of their investment, and it may adversely affect the market price of our ordinary shares. In addition, under Irish law, the directors of an Irish public limited company must have specific authority, as approved by the company’s shareholders, to allot and issue any ordinary shares (other than pursuant to employee equity plans) and, if such directors desire to allot and issue ordinary shares for cash, such shares must first be offered on the same or more favorable terms to the company’s existing shareholders on a pro-rata basis, unless this statutory pre-emption right is disapplied by approval of the company’s shareholders. In May 2017, our shareholders authorized our Board to issue ordinary shares up to our maximum authorized but unissued share capital and to issue such ordinary shares for cash on a non-pre-emptive basis; however, in accordance with Irish law, these share issuance authorities may only be granted for a maximum of five years, at which point they lapse unless renewed by our shareholders. If we are unable to obtain renewal of these existing share issuance authorities from our shareholders, or are otherwise limited by the terms of new share issuance authorities approved by our shareholders, our ability to use our authorized but unissued share capital to effect or to fund acquisition or other transaction opportunities, or to otherwise raise capital, could be adversely affected.

In addition, future investors or lenders may demand, and may be granted, rights superior to those of existing shareholders. If we issue additional debt securities, our existing debt service obligations will increase further. If we are unable to generate sufficient cash to meet these obligations and need to use existing cash or liquidate investments in order to fund our debt service obligations or to repay our debt, we may be forced to curtail our operations. We cannot be certain that additional financing will be available from any of these sources when needed or, if available, will be on acceptable terms. If we fail to obtain additional capital when we need it, we may not be able to execute our business strategy successfully and may have to give up rights to our product platforms, and/or products, or grant licenses on terms that may not be favorable to us.

Currency exchange rates may affect revenues and expenses.

We conduct a large portion of our business in international markets. For example, we derive a majority of our RISPERDAL CONSTA revenues and all of our FAMPYRA, XEPLION and TREVICTA revenues from sales in countries other than the U.S., and these sales are denominated in non-U.S. dollar (“USD”) currencies. We also incur substantial operating costs in Ireland and face exposure to changes in the exchange ratio of the USD and the euro arising from expenses and payables at our Irish operations that are settled in Euro. Our efforts to mitigate the impact of fluctuating currency exchange rates may not be successful. As a result, currency fluctuations among our reporting currency, USD, and the currencies in which we do business will affect our results of operations, often in unpredictable ways. See “Item 7A—Quantitative and Qualitative Disclosures about Market Risk” in this Annual Report for additional information relating to our foreign currency exchange rate risk.

If we identify a material weakness in our internal control over financial reporting, our ability to meet our reporting obligations and the trading price of our ordinary shares could be negatively affected.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our financial statements will not be prevented or detected on a timely basis. Accordingly, a material weakness increases the risk that the financial information we report contains material errors.

We regularly review and update our internal controls, disclosure controls and procedures, and corporate governance policies. In addition, we are required under the Sarbanes-Oxley Act of 2002 to report annually on our internal control over financial reporting. Any system of internal controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. If we, or our independent registered public accounting firm, determine that our internal controls over financial reporting are not effective, or we discover areas that need improvement in the future, these shortcomings could have an adverse effect on our business and financial results, and the price of our ordinary shares could be negatively affected.

Table of Contents

If we cannot conclude that we have effective internal control over our financial reporting, or if our independent registered public accounting firm is unable to provide an unqualified opinion regarding the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our financial statements, which could lead to a decline in the trading price of our ordinary shares. Failure to comply with reporting requirements could also subject us to sanctions and/or investigations by Nasdaq or the SEC or other regulatory authorities.

Risks Related to our Ordinary Shares

The market price for our ordinary shares has been volatile and may continue to be volatile in the future, and could decline significantly.

The market price for our ordinary shares has fluctuated significantly from time to time. During the year ended December 31, 2021, the closing price of our ordinary shares on the Nasdaq Global Select Market ranged from $18.21 to $32.13 per share. The market price of our ordinary shares is likely to continue to be volatile and subject to significant price and volume fluctuations in response to market and industry factors, our results of operations, our ability to maintain and increase sales of our products, the success of our key development programs, our ability to achieve profitability, and other factors, including the risk factors described in this Annual Report. The stock market in general, including the market for biopharmaceutical companies, has experienced extreme price and trading volume fluctuations that have often been unrelated or disproportionate to the operating performance of those companies. In particular, negative publicity regarding pricing and price increases by pharmaceutical companies, and potential legislation to regulate drug pricing, has negatively impacted, and may continue to negatively impact, the market for biopharmaceutical companies. These broad market and industry factors have harmed, and in the future may seriously harm, the market price of our ordinary shares, regardless of our operating performance. We have also experienced significant volatility in the market price of our ordinary shares based on our business performance, including in relation to our commercial sales and the financial guidance that we issue for such sales, results from our clinical development programs, and events relating to regulatory actions and interactions related to our product candidates and commercial products. For example, a series of adverse actions by the FDA in 2018 relating to our NDA for ALKS 5461, our investigational product for the treatment of major depressive disorder, caused the market price of our ordinary shares to decline significantly.

Our business could be negatively affected as a result of the actions of activist shareholders.

Proxy contests and other actions by activist shareholders have been waged against many companies in our industry over the last several years. Activist shareholders may agitate, either publicly or privately, for changes to a company’s board of directors, management, structure, spend or strategic direction, among other things. Such actions may cause significant disruption to a company’s operations and cause a company to expend a significant amount of time and resources in responding to their requests.

In late 2020 and early 2021, we engaged in extensive dialogues with two distinct activist shareholders, resulting in our entry into an agreement with each activist in which we agreed on certain matters relating to our Board and, in the case of one of the agreements, affirmed our commitment to, and plans for, meeting financial profitability targets over a multi-year period. These discussions resulted in the expenditure of significant time and energy by management and our Board and required dedication by the Company of significant resources. We have undertaken, and will continue to implement, several initiatives in order to drive profitability and value creation for our shareholders, but there is no assurance that we will achieve such objectives, or that such achievement and the measures we have taken and will continue to take will decrease the likelihood of activist shareholder engagement in the future. In addition, in January 2022, we received notice from one of these shareholders of its intent to nominate two directors to our Board at our 2022 annual general meeting of shareholders. We have engaged, and plan to continue to engage, with this shareholder in respect of these nominations.

If faced with a proxy contest or other shareholder action or request, we may not be able or willing to respond successfully to the contest, action, or request, which could be significantly disruptive to our business. Even if we are successful, our business could be adversely affected by any proxy contest or activist shareholder action or request involving us because:

Any such activist shareholder contests, actions or requests, or the mere public presence of activist shareholders among our shareholder base, could cause the market price for our ordinary shares to experience periods of significant volatility.

Risks Related to Information Security and Data Privacy

Information security breaches and other disruptions could compromise our information and expose us to liability, which would cause our business and reputation to suffer.

In the ordinary course of our business, we collect and store sensitive data, including IP, our proprietary business information and that of our suppliers and partners, as well as personally identifiable information of patients, clinical trial participants and employees. In addition, the COVID-19 pandemic has required us to implement, and to adapt over time, global remote work flexibility for certain of our employees who are able to work remotely. Our partners and third-party providers also possess certain of our sensitive data. The secure maintenance of all such information and the secure performance of our information technology (“IT”) systems are critical to our operations and business strategy.

As the dependency on our IT systems increases, the confidentiality, integrity and availability of systems and the data that they store is critical to managing our business. While we take prudent measures to secure our IT systems, the risk still exists that such systems may become compromised by successful breaches, malfeasance, human error or technological fault. Certain types of attacks or breaches on our IT systems or infrastructure may go undetected for a prolonged period. Although to our knowledge we have not experienced any material incident or interruption to date, any breakdown, invasion, corruption, destruction or breach of our, our partners’ or our third-party providers’ technology systems could compromise such IT systems and the information stored there could be accessed, modified, publicly disclosed, lost or stolen, which could result in legal claims or proceedings and liability under laws that protect the privacy of personal information, demands for ransom or other forms of blackmail, disruptions to our development programs or commercial operations, damage to our reputation and adverse effects on our business. We retain cybersecurity insurance to cover costs and expenses related to a breach or similar event; however, there is no guarantee that such costs and expenses would not exceed the insurance that we retain.

We may be subject to numerous and varying privacy and security laws, and our failure to comply could result in penalties and reputational damage.

We are subject to laws and regulations covering data privacy and the protection of personal information, including health information. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues which may affect our business. In the U.S., numerous federal and state laws and regulations, including state security breach notification laws, state health information privacy laws, and federal and state consumer protection laws, govern the collection, use, disclosure, and protection of personal information. Each of these laws is subject to varying interpretations by courts and government agencies, creating complex compliance issues for us. If we fail to comply with applicable laws and regulations, we could be subject to penalties or sanctions, including criminal penalties if we knowingly obtain or disclose individually identifiable health information from a covered entity in a manner that is not authorized or permitted by the Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act, or HIPAA.

Numerous other countries have, or are developing, laws governing the collection, use and transmission of personal information as well. The EU and other jurisdictions have adopted data protection laws and regulations, which impose significant compliance obligations. In the EU, for example, the GDPR governs the processing of personal data. The GDPR imposes significant obligations on controllers and processors of personal data, including, high standards for obtaining consent from individuals to process their personal data, robust notification requirements to individuals about the processing of their personal data, a strong individual data rights regime, mandatory data breach notifications, limitations on the retention of personal data and stringent requirements pertaining to health data, and strict rules and restrictions on the transfer of personal data outside of the EU, including to the U.S. The GDPR also imposes additional obligations on, and required contractual provisions to be included in, contracts between companies subject to the GDPR and their third-party processors that relate to the processing of personal data. The GDPR allows EU member states to make additional laws and regulations in order to introduce further conditions, including limitations, with regard to the processing of genetic, biometric or health data.

Adoption of the GDPR increased our responsibility and liability in relation to personal data that we process and may require us to put in place additional mechanisms to ensure compliance. Any failure to comply with the requirements of GDPR and applicable national data protection laws of EU member states could lead to regulatory enforcement actions and significant administrative and/or financial penalties against us (fines of up to €20,000,000 or up to 4% of the total worldwide annual turnover of the preceding financial year, whichever is higher), and could adversely affect our business, financial condition, cash flows and results of operations.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market and shareholder information

Our ordinary shares are traded on the Nasdaq Global Select Market under the symbol “ALKS.” There were 105 shareholders of record of our ordinary shares on February 7, 2022. In addition, the last reported sale price of our ordinary shares as reported on the Nasdaq Global Select Market on February 7, 2022 was $23.55.

Dividends

No dividends have been paid on our ordinary shares to date, and we do not expect to pay cash dividends thereon in the foreseeable future. We anticipate that we will retain all earnings, if any, to support our operations and our proprietary drug development programs. Any future determination as to the payment of dividends will be at the sole discretion of our board of directors and will depend on our financial condition, results of operations, capital requirements and other factors that our board of directors deems relevant.

Repurchase of equity securities

On September 16, 2011, our board of directors authorized the continuation of the Alkermes, Inc. program to repurchase up to $215.0 million of our ordinary shares at the discretion of management from time to time in the open market or through privately negotiated transactions. We did not purchase any shares under this program during the year ended December 31, 2021. As of December 31, 2021, we had purchased a total of 8,866,342 shares under this program at a cost of $114.0 million. The 2026 Term Loans include restrictive covenants that impose certain limitations on our ability to repurchase our ordinary shares.

During the three months ended December 31, 2021, we acquired 100,257 of our ordinary shares, at an average price of $29.30 per share related to the vesting of employee equity awards to satisfy withholding tax obligations.

Irish taxes applicable to U.S. holders

The following is a general summary of the main Irish tax considerations applicable to the purchase, ownership and disposition of our ordinary shares by U.S. holders. It is based on existing Irish law and practices in effect on January 10, 2022, and on discussions and correspondence with the Irish Revenue Commissioners. Legislative, administrative or judicial changes may modify the tax consequences described below.

The statements do not constitute tax advice and are intended only as a general guide. Furthermore, this information applies only to our ordinary shares held as capital assets and does not apply to all categories of shareholders, such as dealers in securities, trustees, insurance companies, collective investment schemes and shareholders who acquire, or who are deemed to acquire, their ordinary shares by virtue of an office or employment. This summary is not exhaustive and shareholders should consult their own tax advisers as to the tax consequences in Ireland, or other relevant jurisdictions where we operate, including the acquisition, ownership and disposition of ordinary shares.

Withholding tax on dividends

While we have no current plans to pay dividends, dividends on our ordinary shares would generally be subject to Irish dividend withholding tax (“DWT”) at 25%, unless an exemption applies. Dividends on our ordinary shares that are owned by residents of the U.S. and held beneficially through the Depositary Trust Company (“DTC”) will not be subject to DWT provided that the address of the beneficial owner of the ordinary shares in the records of the broker is in the U.S.

Dividends on our ordinary shares that are owned by residents of the U.S. and held directly (outside of DTC) will not be subject to DWT provided that the shareholder has completed the appropriate Irish DWT form and this form remains valid. Such shareholders must provide the appropriate Irish DWT form to our transfer agent at least seven business days before the record date for the first dividend payment to which they are entitled.

If any shareholder who is resident in the U.S. receives a dividend subject to DWT, he or she should generally be able to make an application for a refund from the Irish Revenue Commissioners on the prescribed form.

48

Table of Contents

Income tax on dividends

Irish income tax, if any, may arise in respect of dividends paid by us. However, a shareholder who is neither resident nor ordinarily resident in Ireland and who is entitled to an exemption from DWT, generally has no liability for Irish income tax or to the universal social charge on a dividend from us, unless he or she holds his or her ordinary shares through a branch or agency in Ireland which carries out a trade on his or her behalf.

Irish tax on capital gains

A shareholder who is neither resident nor ordinarily resident in Ireland and does not hold our ordinary shares in connection with a trade or business carried on by such shareholder in Ireland through a branch or agency, should not be within the scope of the charge to Irish tax on capital gains on a disposal of our ordinary shares.

Capital acquisitions tax

Irish capital acquisitions tax (“CAT”) is comprised principally of gift tax and inheritance tax. CAT could apply to a gift or inheritance of our ordinary shares irrespective of the place of residence, ordinary residence or domicile of the parties. This is because our ordinary shares are regarded as property situated in Ireland as our share register must be held in Ireland. The person who receives the gift or inheritance has primary liability for CAT.

CAT is levied at a rate of 33% above certain tax‑free thresholds. The appropriate tax‑free threshold is dependent upon (i) the relationship between the donor and the recipient, and (ii) the aggregation of the values of previous gifts and inheritances received by the recipient from persons within the same category of relationship for CAT purposes. Gifts and inheritances passing between spouses are exempt from CAT. Our shareholders should consult their own tax advisers as to whether CAT is creditable or deductible in computing any domestic tax liabilities.

Stamp duty

Irish stamp duty, if any, may become payable in respect of ordinary share transfers. However, a transfer of our ordinary shares from a seller who holds shares through DTC to a buyer who holds the acquired shares through DTC should not be subject to Irish stamp duty. A transfer of our ordinary shares (i) by a seller who holds ordinary shares outside of DTC to any buyer, or (ii) by a seller who holds the ordinary shares through DTC to a buyer who holds the acquired ordinary shares outside of DTC, may be subject to Irish stamp duty, which is currently at the rate of 1% of the price paid or the market value of the ordinary shares acquired, if greater. The person accountable for payment of stamp duty is the buyer or, in the case of a transfer by way of a gift or for less than market value, all parties to the transfer.

A shareholder who holds ordinary shares outside of DTC may transfer those ordinary shares into DTC without giving rise to Irish stamp duty provided that the shareholder would be the beneficial owner of the related book‑entry interest in those ordinary shares recorded in the systems of DTC, and in exactly the same proportions, as a result of the transfer and at the time of the transfer into DTC there is no sale of those book‑entry interests to a third party being contemplated by the shareholder. Similarly, a shareholder who holds ordinary shares through DTC may transfer those ordinary shares out of DTC without giving rise to Irish stamp duty provided that the shareholder would be the beneficial owner of the ordinary shares, and in exactly the same proportions, as a result of the transfer, and at the time of the transfer out of DTC there is no sale of those ordinary shares to a third party being contemplated by the shareholder. In order for the share registrar to be satisfied as to the application of this Irish stamp duty treatment where relevant, the shareholder must confirm to us that the shareholder would be the beneficial owner of the related book‑entry interest in those ordinary shares recorded in the systems of DTC, and in exactly the same proportions or vice‑versa, as a result of the transfer and there is no agreement for the sale of the related book‑entry interest or the ordinary shares or an interest in the ordinary shares, as the case may be, by the shareholder to a third party being contemplated.

The following should be read in conjunction with our consolidated financial statements and related notes beginning on page F‑1 of this Annual Report. The following discussion contains forward‑looking statements. Actual results may differ significantly from those projected in the forward‑looking statements. See “Cautionary Note Concerning Forward‑Looking Statements” on page 3 of this Annual Report. Factors that might cause future results to differ materially from those projected in the forward‑looking statements also include, but are not limited to, those discussed in “Item 1A—Risk Factors” and elsewhere in this Annual Report. A detailed discussion of our 2019 financial condition and results of operations, and of 2020 year-over-year changes as compared to 2019, can be found in “Item 7—Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the SEC on February 11, 2021.

Overview

We have a portfolio of proprietary products that we manufacture, market and sell in the U.S. —VIVITROL, ARISTADA, ARISTADA INITIO and most recently, LYBALVI, which we launched commercially in October 2021. We also earn manufacturing and/or royalty revenues on net sales of products commercialized by our licensees, the most significant of which in 2021 were the long-acting INVEGA products and VUMERITY. We expect VIVITROL, ARISTADA, ARISTADA INITIO, LYBALVI and VUMERITY to generate significant revenues for us in the near‑ and medium‑term as we believe these products are singular or competitively advantaged products in their classes.

In 2021, we incurred an operating loss of $29.3 million, as compared to $112.4 million in 2020. The decrease in the operating loss was primarily due to an increase in revenues of $135.0 million, partially offset by an increase in expenses of $51.9 million. These items are discussed in
