ANASTASIO CURT 4

What Happened

• Curt Anastasio, a director of Core Laboratories (CLB), reported derivative activity on 2026-04-01: he exercised/converted 8,069 derivative shares (reported at $0.00) and those 8,069 shares were disposed the same day (also reported at $0.00). In addition, he was granted/received 7,895 restricted shares (reported at $0.00) as an award/derivative.

Key Details

• Transaction date(s): 2026-04-01 (filed 2026-04-07).
• Reported prices/values: all transactions listed at $0.00 per share and $0 total in the filing.
• Shares after transaction: filing does not state total beneficial ownership after these transactions.
• Footnotes:
  • F2: The restricted shares that converted/vested did so at the end of a one-year vesting period ending 4/1/2026.
  • F1: The 7,895 Restricted Shares granted will vest (no performance criteria) on 4/1/2027 and are subject to a possible deferral election under Treasury Reg. 1.409A-2; distributions of vested shares occur after separation from the Board.
• Filing timeliness: Filed 2026-04-07 for a 2026-04-01 transaction — this appears to be filed late relative to the usual two-business-day Form 4 deadline.

Context

• The filing shows a same‑day conversion/exercise and disposal of 8,069 derivative shares; the document reports $0.00 per share and gives no sale proceeds or reason for the disposal. The 7,895 shares are a new restricted award that will vest next year (4/1/2027), so the most material ongoing change is the future vesting of those RSUs rather than a market purchase.
