HIGGINS JOHN L 4

What Happened
John L. Higgins, a director of OmniAb, had 13,172 restricted stock units (RSUs vest) on January 30, 2026. The Form 4 reports a conversion/exercise-type transaction (code M) for 13,172 shares (acquired via conversion) and an entry showing 13,172 shares disposed at $0.00. No cash proceeds are reported for the disposal.

Key Details

• Transaction date: 2026-01-30. Transaction code: M (exercise/conversion of derivative).
• Reported activity: 13,172 shares converted/acquired (N/A price) and 13,172 shares disposed at $0.00.
• Shares owned after transaction: not specified in the provided filing.
• Footnotes: F1 — these shares represent an RSU vesting installment (RSUs vest in three substantially equal annual installments beginning Jan 30, 2024, subject to continued service). F2 — each RSU equals the contingent right to receive one share of common stock.
• Filing timeliness: filed the same day (no late filing indicated).

Context
This filing documents RSU vesting and conversion rather than an open-market purchase or sale. The reported $0.00 disposal indicates the shares were not sold for cash on the open market; such zero-dollar dispositions commonly reflect net settlement, tax withholding, or administrative transfers tied to RSU settlement rather than a market sale. This is routine compensation-related activity and should be interpreted accordingly.
