Alkermes Stock Drops 5% Despite Revenue Surge as GAAP Net Income Narrows to $0.5 Million

Alkermes plc shares fell 5% to $50.05 after its second-quarter 2026 report showed a 27% revenue jump to $496.0 million but GAAP net income collapsed to $0.5 million from $87.1 million a year earlier. Proprietary net sales reached $411.7 million, led by VIVITROL at $124.5 million, ARISTADA at $96.7 million, LYBALVI at $94.0 million, and newly integrated narcolepsy therapy LUMRYZ at $96.6 million, while manufacturing and royalty revenues added $79.0 million. Adjusted EBITDA grew to $139.2 million, yet integration costs and higher R&D and SG&A spending weighed on bottom-line earnings. The company also announced that CEO Richard Pops will become Executive Chairman and COO Blair Jackson will take over as CEO on August 1.

Alkermes shares pull back after mixed Q2 results, fair value debate splits analysts

Alkermes shares fell 7.37% over the past week to US$48.99 after the company reported second-quarter 2026 results that showed higher revenue but a significantly lower quarterly net income. The most-followed narrative on Simply Wall St pegs fair value at US$47.69, suggesting the stock is about 3% overvalued, while the platform's own discounted cash flow model estimates fair value at US$99.55, roughly 51% above the current price. The bullish case rests on strong demand for proprietary neuroscience products Vivitrol, Aristada, and Lybalvi, driven by expanding diagnosis rates and greater patient access, though risks remain around orexin trial outcomes and product concentration. Longer-term returns remain robust, with a 90-day share price gain of 46.76% and a one-year total shareholder return of 84.52%.

Alkermes Shares Rise 9.3% on Positive Alixorexton Phase 2 Data and Russell 2000 Addition

Alkermes shares climbed 9.3% after the company reported detailed positive phase 2 Vibrance‑2 results for its oral orexin 2 receptor agonist alixorexton in narcolepsy type 2 and was added to the Russell 2000 Dynamic Index. The Vibrance‑2 data met dual primary endpoints on wakefulness and daytime sleepiness with sustained benefits, and showed encouraging safety and patient‑reported gains in fatigue and cognition. These results sharpen focus on the upcoming phase 3 Brilliance program as the key catalyst for Alkermes' orexin pipeline, which the company hopes will become a meaningful new pillar alongside Vivitrol, Aristada, and Lybalvi. The Russell 2000 Dynamic Index inclusion is seen as visibility‑enhancing but not a material driver of the core risk‑reward balance. Alkermes' narrative projects $2.1 billion in revenue and $264.8 million in earnings by 2029, requiring 11.1% yearly revenue growth.

Alkermes plummets after mid-stage narcolepsy data for alixorexton

Alkermes shares fell about 31% in after-hours trading Wednesday after the company reported phase 2 results for its narcolepsy type 2 drug candidate alixorexton. The Vibrance-2 trial met its dual primary endpoints, showing statistically significant improvements from baseline on the Maintenance of Wakefulness Test and the Epworth Sleepiness Scale at week eight compared to placebo. Patient-reported improvements in wakefulness were maintained through a five-week open-label extension, and those on alixorexton also saw improvements in fatigue versus placebo, with no serious treatment-emergent adverse events reported. Alkermes said it has begun a phase 3 program examining once-daily and split dose regimens of the oral selective orexin 2 receptor agonist.
