McMullen James 4

What Happened
James McMullen, Controller of Enact Holdings (ACT), had 594 restricted stock units (RSUs vest and convert to common shares) on April 1, 2026.

Context
This was an RSU vesting and a routine tax‑withholding event, not an open‑market purchase or sale intended as a market signal. Withholding shares to cover taxes is common when equity awards vest; it reduces the number of net shares the insider receives but does not represent a discretionary sale. The Form 4 was filed shortly after the April 1 transaction date.
