Annexon (ANNX) CFO Jennifer Lew Receives Stock Awards

What Happened

Jennifer Lew, Chief Financial Officer of Annexon, was granted two awards on February 19, 2026: 62,500 restricted stock units (RSUs) and a 250,000-share derivative award. Both grants are reported at $0.00 per share (no cash paid at grant).

Key Details

Transaction date: February 19, 2026. Filing date: February 23, 2026 (four days after the transactions).
Prices and values: both awards reported at $0.00 per share (grant). No cash purchase or sale occurred.
Vesting/terms (from filing footnotes):
- The 62,500 RSUs: 1 RSU = 1 share on vesting. Vesting is 1/3rd of the RSUs annually each February 19, with the first vesting on February 19, 2027, subject to continued service.
- The 250,000 derivative award: vests 1/48th each month starting Feb 19, 2026 (Vesting Commencement Date), so it will be fully vested on the fourth anniversary, subject to continued service.
Shares owned after the transaction: not disclosed in the provided filing.
Filing timeliness: filed Feb 23, 2026 — four days after the reported transactions, which appears to exceed the SEC’s typical 2-business-day Form 4 deadline.

Context

These were grants/awards (not open-market purchases or sales). RSUs convert to shares only as they vest; the derivative award is subject to monthly vesting over four years. Such awards are routine equity compensation for executives and do not by themselves indicate a buying or selling decision.
