“We have made significant strides across our commercial and development portfolios over the course of 2021. With the recent commercial launch of LYBALVI^®^, we have expanded our psychiatry franchise and added an important new growth opportunity that leverages our experience and capabilities in the antipsychotic market. Within our development pipeline, we initiated clinical studies designed to support potential registration of nemvaleukin in mucosal melanoma and platinum-resistant ovarian cancer. We also initiated a phase 1 study of ALKS 1140 and advanced our preclinical orexin 2 receptor agonist program. Each of these important achievements demonstrates the continued execution of our strategy to advance differentiated medicines in neuroscience and oncology,” said Richard Pops, Chief Executive Officer of Alkermes. “As we look ahead, we believe we are well-positioned to deliver long-term growth and value creation, driven by our diversified commercial business, our advancing development pipeline and our focus on profitability.”

Financial Expectations for 2021

Alkermes reiterates its financial expectations for 2021 set forth in its press release dated July 28, 2021. These financial expectations assume improvement in patient access to treatment providers and further normalization of the treatment system in the fourth quarter of 2021. If patient access does not improve or the treatment system does not normalize as anticipated, or if new COVID-19-related disruptions emerge, the company’s ability to meet these expectations could be negatively impacted.

“We are pleased to report another strong quarter that reflects our continued focus on commercial execution, with solid year-over-year growth for VIVITROL and ARISTADA, and on driving operational efficiencies,” commented Iain Brown, Chief Financial Officer of Alkermes. “As we look ahead, we believe that we are in a strong financial position to successfully launch LYBALVI and invest in our pipeline of development candidates as we seek to drive long-term value creation and profitability.”

Recent Events:

Psychiatry

In October 2021, the company announced the commercial availability of LYBALVI (olanzapine and samidorphan) 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^2^. LYBALVI is a once-daily, oral atypical antipsychotic composed of olanzapine, an established antipsychotic agent, co-formulated with samidorphan, a new chemical entity, in a single bilayer tablet.

Oncology

In August 2021, the U.S. Food and Drug Administration (FDA) granted Fast Track designation to nemvaleukin alfa (nemvaleukin) for the treatment of mucosal melanoma. This followed the FDA’s grant of Orphan Drug designation to nemvaleukin for the treatment of mucosal melanoma and the recent initiation of ARTISTRY-6, a global phase 2 trial evaluating the anti-tumor activity, safety and tolerability of nemvaleukin monotherapy in patients with melanoma who have been previously treated with anti-PD-(L)1 therapy.
In October 2021, the FDA granted Fast Track designation to nemvaleukin in combination with pembrolizumab for the treatment of platinum-resistant ovarian cancer.
--- ---
In October 2021, the company announced the initiation of ARTISTRY-7, a global phase 3 trial evaluating the anti-tumor activity and safety of intravenously administered (IV) nemvaleukin in combination with pembrolizumab compared to investigator’s choice chemotherapy in patients with platinum-resistant ovarian cancer.
--- ---

Neuroscience

In October 2021, the company initiated a phase 1, first-in-human study evaluating the safety and tolerability of ALKS 1140 in healthy subjects. ALKS 1140 is a novel, investigational CoREST-selective (co-repressor of repressor element-1 silencing transcription factor) HDAC inhibitor candidate for the treatment of neurodegenerative and neurodevelopmental disorders. ALKS 1140 is designed to increase functional synaptic connections and synaptic integrity in the brain.

Non-GAAP Financial Measures

This press release includes information about certain financial measures that are not prepared in accordance with GAAP, including non-GAAP net income (loss) and non-GAAP basic and diluted earnings (loss) per share. 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.

Non-GAAP net income (loss) adjusts for certain one-time and non-cash charges by excluding from GAAP results: share-based compensation expense; amortization; depreciation; non-cash net interest expense; certain other one-time or non-cash items; and the income tax effect of these reconciling items.

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 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, non-GAAP net income (loss) and non-GAAP basic and diluted earnings (loss) per share 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, non-GAAP net income (loss) and non-GAAP basic and diluted earnings (loss) per share 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.

Note Regarding Forward-Looking Statements

Certain statements set forth in this press release 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: the company’s expectations concerning its future financial and operating performance, business plans or prospects, including its ability to deliver, and the expected drivers of, growth and value creation; the company’s expectations of improvement in patient access to treatment providers and further normalization of the treatment system; the potential therapeutic and commercial value of the company’s marketed and development products; the company’s expectations concerning its future development activities, including further investment in and advancement of the company’s neuroscience and oncology development pipeline; and the company’s expectations concerning its commercial activities, including its ability to successfully launch LYBALVI and to leverage its commercial experience and capabilities in the antipsychotic market. The company cautions that forward-looking statements are inherently uncertain.
