Alnylam grants CEO Greenstreet $18.0 million performance-based special equity award
Alnylam's Board granted CEO Yvonne Greenstreet a special performance share award effective March 2, 2026, with a target of 55,373 shares and a stated face value of $18.0 million. The award pays out only if the stock's future 30-day average price reaches thresholds starting at $500 and reaching $800 by December 31, 2029, so it creates no value unless shareholders see significant stock price gains.
Key points
- Target award: 55,373 performance share units, face value $18.0 million based on the $325.07 closing price on the Grant Date
- Vesting range: 50% to 200% of target, tied to future average stock price thresholds of $500, $600, $700 and $800
- Baseline threshold of $500 must be met or the award is forfeited in full; vesting date is December 31, 2029
- The award was granted concurrently with the March 2, 2026 annual equity grants to Greenstreet and other executives
