Mercer William S 4

What Happened

• William S. Mercer, a director of Ategrity Specialty Insurance Co Holdings (ASIC), had 980 restricted stock units (RSUs) convert into 980 shares on June 11, 2026 (reported on Form 4 filed 2026-06-15). The filing shows an acquired conversion of 980 shares and a simultaneous disposition of 980 shares at $0.00. The $0 disposition indicates the shares were likely surrendered/withheld to satisfy tax withholding or other withholding obligations, not an open‑market sale.

Key Details

• Transaction date: June 11, 2026; Form 4 filed: June 15, 2026 (timely filing).
• Transaction type/code: M — exercise or conversion of derivative (RSU conversion to common stock).
• Shares converted: 980; Shares disposed: 980 at $0.00 (reported proceeds $0).
• Footnotes: F1 — each RSU converts to one share; F2 — these RSUs were part of a June 11, 2025 grant of 2,941 RSUs vesting in three equal annual installments (remaining installments vest on June 11, 2027 and June 11, 2028).
• Shares owned after the transaction: not specified in the data provided in this summary.

Context

• Converting RSUs and immediately withholding/surrendering some or all of the resulting shares to cover taxes is a routine administrative step and does not necessarily indicate a trading view on the stock. Purchases are typically more informative about insider sentiment than grant conversions or withholding events.
