Wong-Sarad Grace 4

What Happened

• Grace Wong-Sarad, Principal Accounting Officer of Alector, sold 8,071 shares on 2026-03-02 in open-market transactions. The weighted-average sale price was $2.12 per share, for total proceeds of $17,138. The filing indicates the sales were to satisfy tax obligations tied to vested restricted stock units (RSUs), so this was a routine tax-withholding sale rather than a discretionary investment decision.
