Insights

Equity compensation and insider trading analyst

Routine equity awards combined with a planned 10b5-1 sale; overall neutral.

The reporting person, a senior commercial executive at Alkermes plc, received sizable equity compensation on 3/2/2026: an option for 66,430 shares and 30,854 restricted stock units, both granted at $0.00. These awards vest in four equal annual installments starting on 3/2/2027, aligning incentives with longer-term company performance.

On the same date, he executed an open-market sale of 6,000 ordinary shares at $30.00 per share, totaling $180,000. A footnote states the sale was made under a Rule 10b5-1 trading plan adopted on 11/19/2025, indicating it was pre-arranged rather than opportunistic. After the sale, he retained 109,769 ordinary shares, alongside the newly granted options and RSUs.

The combination of long-vesting awards and a relatively modest, pre-planned sale suggests standard executive compensation and liquidity management. Future company filings may show how much of these awards ultimately vest and are exercised over the vesting period beginning in 2027.
