Ahn Cristina E. 4

What Happened

• Cristina E. Ahn, Chief Accounting Officer of Octave Specialty Group, had a portion of her 2025 LTIP settled on March 10, 2026: 835 restricted stock units (RSUs) were converted into common shares, and the company withheld 203 shares to satisfy tax withholding (recorded at $4.90/share, totaling $995). On March 23, 2026 she received a new grant of 8,067 RSUs as part of her 2026 Long Term Incentive Plan award. The 8,067 RSUs will vest in three equal annual installments beginning March 23, 2027.
• These actions are not open‑market purchases or sales by Ahn; they are an RSU settlement (with withholding for taxes) and a new RSU grant (an award/acquisition).

Key Details

• Transaction dates: March 10, 2026 (RSU settlement and tax withholding) and March 23, 2026 (RSU grant).
• Prices/values reported: 203 shares withheld at $4.90/share = $995. No per‑share exercise price reported for RSU conversion; RSUs convert 1-for-1 to common stock (each RSU = one share).
• Shares owned after transaction: Not disclosed in this Form 4 filing.
• Footnotes: F1–F3 explain these were RSU conversions/settlements from the 2025 LTIP and that each RSU equals one contingent share; F2 notes shares were withheld to satisfy tax withholding; F4 details the 8,067-RSU grant and vesting schedule (three equal annual installments starting 3/23/2027).
• Filing timeliness: The report was filed March 25, 2026, which is after the March 10 transaction—meaning the March 10 settlement was reported late on this Form 4.

Context

• RSU settlements and subsequent tax-withholding are routine administrative events and do not necessarily signal a buy or sell decision by the insider. The March 23 grant is an award (A) — a common form of executive compensation — and is distinct from an open‑market purchase.
• Transaction codes in this filing: M = exercise/conversion of derivative (RSU settlement), F = tax withholding, A = grant/award.
