What Happened
Teo Sow Hang, Core Laboratories' (CLB) Chief Accounting Officer & Treasurer, was granted a performance-based equity award covering 7,526 shares on February 12, 2026. The grant is reported as a derivative award with an acquisition price of $0.00 — no cash was paid at grant and the shares do not vest immediately.

Key Details

• Transaction date: 2026-02-12; Form 4 filed: 2026-02-17 (filed 5 days after the transaction; appears late relative to the 2-business-day Form 4 rule).
• Grant: 7,526 shares, reported at $0.00 (derivative award, code A).
• Shares owned after transaction: Not specified in the provided filing.
• Footnote (F1): Vesting depends on continued employment (or death/disability while employed) and performance over a three-year period (Jan 1, 2026 – Dec 31, 2028). At the end of the period: 100% vests if Core Labs ranks at the 55th percentile ROIC vs. the Bloomberg Peer Group (BPG); up to 200% vests at the 85th percentile, with straight-line interpolation between 55th–85th percentiles. The Compensation Committee will determine final measurement.

Context
This is a performance-based restricted-equity style grant, not an immediate purchase or sale. Such awards only convert into common shares if performance and service conditions are met, so they do not create immediate marketable shares but may result in future dilution if targets are achieved and shares vest. The late filing means the public learned of the grant after the usual 2-business-day reporting window; the substance of the award and vesting conditions remain as disclosed.
