However, trading volume was unusually low at only 115,370 shares, a 93% decline from its typical volume, suggesting cautious optimism among investors.

The Investment Story: September was a pivotal month for Alkermes, marked by a strong Q2 earnings beat and highly encouraging Phase 2 data for alixorexton, fueling analyst upgrades and increased institutional interest, though tempered by a conservative FY2025 guidance.

What It Means for Investors: The positive data and analyst reactions suggest potential undervaluation, with price targets ranging from $35.00 to $46.00. Investors should monitor the upcoming Phase 3 program for alixorexton and the defense of Lybalvi's patent, as these are key catalysts for future growth.

Looking Ahead: Investors should closely watch for the initiation of the global Phase 3 program for alixorexton in Q1 2026 and the progress of ongoing Phase 2 studies for alixorexton in narcolepsy type 2 and idiopathic hypersomnia. Monitoring the outcome of the patent infringement lawsuits will also be crucial.

The Bottom Line: Alkermes is demonstrating resilience and potential with its promising drug pipeline and proactive defense of its intellectual property. While guidance remains conservative, the company's strong financial position and institutional support provide a foundation for potential long-term growth, making it a compelling investment candidate for those willing to monitor key upcoming catalysts.
