DUBLIN, July 29, 2025 — Alkermes plc (Nasdaq: ALKS) today reported financial results for the second quarter of 2025.

“Our second quarter results reflect strong performance across all three of our proprietary products and robust profitability and cash flow generation,” said Richard Pops, Chief Executive Officer of Alkermes. “Against the backdrop of solid financial performance, the recently announced positive topline results from Vibrance-1, our phase 2 study of alixorexton (ALKS 2680) in narcolepsy type 1, were an important milestone in the development program and underscore the differentiated features of alixorexton. These data also highlight the potential of orexin 2 receptor agonists to transform the treatment of narcolepsy. As we prepare to initiate a global phase 3 program, we look forward to sharing detailed results from Vibrance-1 at the upcoming World Sleep Congress and topline results from our Vibrance-2 study in patients with narcolepsy type 2 this fall.”

Non-GAAP Financial Measures

This press release includes information about certain financial measures that are not prepared in accordance with generally accepted accounting principles in the U.S. (GAAP), including EBITDA and Adjusted EBITDA. 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.

EBITDA represents earnings before interest, tax, depreciation and amortization. Adjusted EBITDA excludes share-based compensation expense in addition to the components of EBITDA from earnings.

The company’s management and board of directors utilize these non-GAAP financial measures to evaluate the company’s performance. 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. However, EBITDA and Adjusted EBITDA are not measures of financial performance under GAAP and, accordingly, should not be considered as alternatives to GAAP measures as indicators of operating performance. Further, EBITDA and Adjusted EBITDA should not be considered measures of the company’s liquidity.

A reconciliation of GAAP to non-GAAP financial measures has been provided in the tables included in this press release.
