What Happened

• Martha Z. Carnes, a director of Core Laboratories (CLB), completed multiple equity transactions on April 1, 2026. According to the Form 4, she exercised/converted 8,069 derivative shares (code M) and disposed of the same 8,069 shares the same day (code M). She also acquired 7,895 restricted/derivative shares (code A). The Form 4 reports $0.00 per-share values for these entries.

Key Details

• Transaction date: 2026-04-01; Form 4 filed: 2026-04-07 (appears to be a late filing).
• Exercises/conversions: 8,069 shares acquired and 8,069 shares disposed (same-day), reported at $0.00 per share.
• Award/grant: 7,895 restricted/derivative shares acquired, reported at $0.00 per share.
• Net effect in this filing: +7,895 shares from the award after an 8,069-share exercise/sale; total common shares owned after these transactions is not specified in the provided excerpt.
• Footnotes: F2 states the restricted shares vested at the end of a one-year vesting period on April 1, 2026. F1 describes terms for a different set of restricted shares that vest on April 1, 2027 and may be subject to deferral rules under Treasury Reg. 1.409A-2.
• No 10b5-1 plan, tax withholding, or explicit sale price per share was provided in the excerpt.

Context

• The same-day exercise and disposition of 8,069 shares is consistent with a cashless exercise or immediate sale of exercised shares (exercise followed by sale). The 7,895 shares appear to be restricted shares that vested (per footnote F2). These mixed transactions include both a sale and an acquisition; purchases/vests can be viewed as a more direct bullish signal, while routine option exercises and subsequent sales are commonly used for liquidity or tax purposes. This filing was submitted several days after the transaction date, which investors may note for timeliness.
