What Happened

Jesse Wayne Hall, Chief Medical Officer of Aclaris Therapeutics (ACRS), had 36,375 restricted stock units (RSUs convert/vest) on May 1, 2026. The issuer converted those RSUs into shares and withheld 9,330 shares to cover tax withholding obligations (sale/withholding), valued at $4.41 per share for a withholding amount of $41,145. Net shares delivered to Hall after withholding were 27,045.

Key Details

Tax withholding: 9,330 shares withheld and disposed (code F) at $4.41/share for $41,145.
Net shares received by the reporting person: 36,375 − 9,330 = 27,045 shares.
Shares owned after the transaction: not disclosed in the provided filing details.
Relevant footnotes: F1 — each RSU equals one contingent share; F2 — issuer withheld shares to satisfy tax withholding; F3 — these RSUs vest in four equal annual installments beginning May 1, 2025 (this was the first installment).

Context

This was a vesting/settlement of RSUs, not an open-market purchase or voluntary sale. Withholding shares to pay taxes is routine and is similar to a “sell-to-cover” — it does not necessarily signal insider views on the company’s stock.
For RSU awards, the material event is the vesting schedule (here, four annual installments). Purchases by insiders are generally more informative about confidence; vesting and withholding are compensation mechanics.
