Crouse Steven C. 4

What Happened
Steven C. Crouse, a director of OmniAb, reported derivative activity and awards on 2026-06-17. The Form 4 shows: (a) an exercise/conversion of 20,000 derivative units resulting in acquisition of 20,000 shares (price N/A), (b) a related exercise/conversion/disposition of 20,000 derivative units with $0 reported proceeds, and (c) awards/grants of 20,000 and 40,000 Restricted Stock Units (RSUs) (total 60,000 RSUs) reported as acquired at $0. No cash proceeds or market sale proceeds are reported.

Key Details

• Transaction date: 2026-06-17; Form 4 filed 2026-06-18 (timely filing).
• Transaction codes: M = exercise/conversion of derivative; A = award/grant (RSUs).
• Reported share amounts: 20,000 (acquired via exercise/conversion), 20,000 (disposed at $0), and two RSU awards of 20,000 and 40,000 (total 60,000 RSUs).
• Reported prices/values: exercise/converted shares shown as N/A or $0; RSUs shown at $0 (typical for equity awards). No cash proceeds reported.
• Shares owned after transaction: not specified in the summary data provided here; see the full Form 4 for total post-transaction holdings.
• Footnotes of note:
  • F1/F3: The RSUs relate to a grant on June 17, 2025 and vest on the earlier of the next annual meeting or the first anniversary of the grant.
  • F2: Each RSU represents a contingent right to one share of common stock.
  • F4: Stock options/derivatives referenced vest on a similar earlier-of schedule.
• Filing timeliness: filed the day after the transaction (no late filing flag indicated).

Context

• Derivative transactions (code M) indicate options or similar instruments were converted/exercised. The presence of a $0 disposition line alongside an acquisition line often reflects internal settlement mechanics (for example, net settlement or shares withheld to satisfy tax obligations), but the Form 4 does not specify the reason.
• RSU awards are not open-market purchases and reflect compensation/vested awards that convert to shares per the vesting terms; they do not necessarily signal a purchase decision by the insider.
• No sale-for-cash in an open market is reported; the filing documents equity awards and conversions rather than a discretionary purchase or sale.
