Sana (SANA) SVP Susan Wyrick Converts RSUs, Sells 4,387 Shares for Taxes

What Happened

Susan D. Wyrick, SVP, Finance & Accounting and Principal Accounting Officer at Sana (SANA), had restricted stock units (RSUs) convert into 13,666 shares (10,416 on 2026-03-06 and 3,250 on 2026-03-07) at an effective $0 exercise price. To satisfy tax withholding, 4,387 of those shares were disposed on 2026-03-09 (3,342 shares at $3.13 for $10,460 and 1,045 shares at $3.10 for $3,240), totaling $13,700. Net shares retained from the vesting: 9,279.

Key Details

Transaction types: M = conversion/vesting of derivative (RSU), F = shares used to satisfy tax liability (withholding/disposition).
Dates: RSU conversions on 2026-03-06 and 2026-03-07; tax-withholding dispositions on 2026-03-09. Form 4 filed 2026-03-10 (timely).
Prices/values: RSUs converted at $0; shares withheld sold at $3.13 and $3.10 for a combined proceeds/withholding value of $13,700.
Shares after transaction: filing does not list total holdings; net retained from these vesting events = 9,279 shares (13,666 acquired − 4,387 withheld).
Footnotes: F1 = each RSU equals one contingent share; F2/F3 describe separate vesting schedules for the two awards (partial vesting on 3/6/2026 and 3/7/2026 with remaining installments in later years).

Context

These transactions reflect routine RSU vesting and tax-withholding rather than an open-market purchase or discretionary sale. Conversions at $0 are standard for RSUs; the subsequent disposition was a tax withholding (common practice, not necessarily a bearish signal).
Because two different award schedules vested, this filing shows two separate vesting events converted to shares and then partially withheld to cover taxes.
