First Quarter 2026Financial Results & Business Update May 5, 2026 Exhibit 99.2

Forward-Looking Statements and Non-GAAP Financial Information Certain statements set forth in this presentation constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, as amended, including, but not limited to, statements concerning: Alkermes plc’s (the “Company”) expectations with respect to its current and future financial, commercial and operating performance, business plans or prospects, including profitability. The Company cautions that forward-looking statements are inherently uncertain. Actual performance and results may differ materially from those expressed or implied in the forward-looking statements due to various risks, assumptions and uncertainties. These risks, assumptions and uncertainties include, among others: whether the Company is able to achieve its financial expectations, including those related to profitability; the Company’s commercial activities may not result in the benefits that the Company anticipates; the businesses of the Company and Avadel Pharmaceuticals plc (“Avadel”) may not be effectively integrated and the expected benefits and value of the acquisition may not be achieved; there may be unknown or inestimable liabilities, potential litigation and transaction costs associated with the acquisition; clinical development activities may not be completed on time or at all; the results of the Company’s development activities may not be positive, or predictive of final results from such activities, results of future development activities or real-world results; potential changes in the cost, scope, design or duration of the Company’s development activities; the unfavorable outcome of arbitration, litigation, including so-called “Paragraph IV” litigation, or other proceedings or other disputes related to the Company’s products or products using the Company’s proprietary technologies; the U.S. Food and Drug Administration or other regulatory authorities may make adverse decisions regarding the Company’s products; the Company and its licensees may not be able to continue to successfully commercialize their products or support growth of such products; there may be a reduction in payment rate or reimbursement for the Company’s products or an increase in the Company’s financial obligations to government payers; the Company’s products may prove difficult to manufacture, be precluded from commercialization by the proprietary rights of third parties, or have unintended side effects, adverse reactions or incidents of misuse; and those risks, assumptions and uncertainties described under the heading “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended Dec. 31, 2025 and in subsequent filings made by the Company with the U.S. Securities and Exchange Commission (“SEC”), which are available on the SEC’s website at www.sec.gov, and on the Company’s website at www.alkermes.com in the ‘Investors – SEC Filings’ section. Existing and prospective investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. Except as required by law, the Company disclaims any intention or responsibility for updating or revising any forward-looking statements contained in this presentation. Non-GAAP Financial Measures: This presentation includes information about certain financial measures that are not prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”), including EBITDA (earnings before interest, taxes, depreciation and amortization) and Adjusted EBITDA (excludes share‐based compensation expense and non‐recurring gains or losses in addition to the components of EBITDA from earnings). The Company provides these non-GAAP financial measures of the Company’s performance to investors because management believes that these non-GAAP financial measures, when viewed with the Company’s results under GAAP and the accompanying reconciliations, are useful in identifying underlying trends in ongoing operations. These non-GAAP measures are not based on any standardized methodology prescribed by GAAP and are not necessarily comparable to similar measures presented by other companies. Reconciliations of non-GAAP financial measures to the most directly comparable GAAP financial measures, to the extent reasonably determinable, can be found in the Appendix of this presentation. Note Regarding Trademarks: The Company and its affiliates are the owners of various U.S. federal trademark registrations (®) and other trademarks (TM), including ARISTADA®, ARISTADA INITIO®, LUMRYZ®, LYBALVI® and VIVITROL®. Any other trademarks referred to in this presentation are the property of their respective owners.
