Boston Shoemake Alicia r 4

What Happened

• Alicia Boston Shoemake, Senior Vice President and General Counsel of Tetra Technologies (TTI), had 19,427 restricted stock units (RSUs) vest and convert into 19,427 shares on February 28, 2026. To cover tax withholding on the vesting, 7,645 of those shares were surrendered to the company at an implied value of $8.66 per share, totaling $66,206. Net shares retained from this vesting event: 11,782 shares. The conversion is recorded as a derivative exercise/conversion (transaction code M) and the withholding as tax payment (code F).

Key Details

• Transaction date: February 28, 2026.
• Conversion: 19,427 RSUs converted to 19,427 common shares (reported as M; $0 per-share acquisition price because RSUs convert one-for-one).
• Tax withholding: 7,645 shares surrendered at $8.66 each for $66,206 (reported as F).
• Net shares retained from this vesting: 11,782 shares.
• Footnotes: F1–vested RSUs were granted 2/28/2025 and convert one-for-one; F2–units surrendered for tax withholding; F3–remaining unvested RSUs vest every six months through 2/25/2028.
• Filing timing: Form 4 filed 2026-03-02 for a 2026-02-28 transaction (appears timely).

Context

• This was a routine vesting of RSUs with shares surrendered to the issuer to satisfy tax withholding—common practice and not an open-market sale. The derivative code (M) here reflects conversion/exercise of RSUs rather than a cash purchase. The remaining unvested portion of the award continues to vest semiannually through February 25, 2028.
