FOEHR MATTHEW W 4

What Happened
Matthew W. Foehr, President, CEO and a director of OmniAb (OABI), had 36,459 Restricted Stock Units (RSUs) vest on April 7, 2026, converting into 36,459 shares (acquired at $0.00). On the same day he sold 19,244 of those shares in an open-market sell-to-cover transaction for a weighted average price of $1.49, producing gross proceeds of about $28,674. The RSU conversion and subsequent sale were routine vesting/tax-related actions rather than an independent, discretionary stock sale.

Key Details

• Transaction date: April 7, 2026.
• Vesting/conversion: 36,459 RSUs → 36,459 shares (acquired at $0.00; reported as derivative exercise/conversion, code M).
• Sale: 19,244 shares disposed in open market at a weighted average price of $1.49; price range $1.46–$1.53; proceeds ≈ $28,674.
• Net shares retained from this vesting: 36,459 − 19,244 = approximately 17,215 shares (remaining after the sell-to-cover).
• Footnotes: RSUs vest in annual installments; each RSU equals one share (F1–F2). The sale was a mandated sell-to-cover to satisfy tax withholding (F3). The reported sale price is a weighted average and was executed in multiple trades (F4).
• Filing timeliness: No late filing flag indicated in the provided data.

Context
This reporting reflects RSU vesting and mandatory sell-to-cover tax withholding, a common practice for equity awards. The conversion of RSUs (a derivative right) into shares and the partial sale to cover taxes does not necessarily indicate a personal decision to liquidate stock for investment reasons; it is largely administrative. Purchases would be more indicative of a bullish signal; this filing documents compensation vesting and related tax-sales.
