Alnylam (ALNY) Director Amy W. Schulman Receives RSU and Option Award

What Happened

These are awards (compensation), not open-market purchases or sales.

Key Details

Transaction date: 2026-05-20; Filing date: 2026-05-22 (filed timely under the Form 4 two-business-day rule).
Price: $0.00 per share — these are compensation grants, not cash purchases.
Shares owned after transaction: Not specified in the provided filing details.
Footnotes / vesting notes:
- The 838 shares are RSUs; each RSU converts to one share. RSUs vest in full on the earlier of the first anniversary of the grant or earlier retirement/resignation, provided such retirement/resignation occurs no more than 90 days before the first anniversary.
- The 1,802-share derivative award is subject to a similar vesting condition (it will vest in full on the earlier of the first anniversary of the grant or certain earlier retirement/resignation timing).

Context

Grants like RSUs or option awards are standard director compensation and do not necessarily indicate buying or selling sentiment. They generally vest over time or upon specified conditions; they are not immediate cash purchases or sales.
The derivative award should be understood as a future right to obtain shares (subject to vesting), not an immediate share transfer.
