SANDERSON MATTHEW 4

What Happened

• Matthew Sanderson, Executive Vice President of Tetra Technologies (TTI), received a grant of 40,374 restricted stock units (RSUs) on February 18, 2026. The award is a derivative grant (code A) — RSUs convert to shares upon vesting. Using the closing stock price on the grant date ($11.15), the grant is roughly valued at $450,170.10. This is an award/grant (not an open-market buy or sale).

Key Details

• Transaction date: 2026-02-18; Form filed: 2026-02-20 (timely).
• Grant: 40,374 RSUs; grant price shown as $0.00 because RSUs are awarded, not purchased.
• Approximate grant value at grant-date close: $11.15 × 40,374 ≈ $450,170.10.
• Shares owned after transaction: not specified in this Form 4.
• Footnotes:
  • F1: Each RSU converts to one share upon vesting; grant-date close = $11.15.
  • F2: Vesting schedule — one-third vests on Feb 18, 2027; then one-sixth vests each Aug 25 and Feb 25 thereafter; fully vested Feb 25, 2029, subject to continued service. Issuer may settle vested RSUs in shares, cash, or a mix.
• No 10b5-1 plan, tax-withholding, or late-filing flags are indicated.

Context

• RSU grants are a common form of executive compensation to align management with shareholder interests; they do not represent immediate ownership until vested and settled.
• Because the award vests over multiple dates through 2029 and may be settled in cash or stock, it should be viewed as long-term compensation rather than an immediate market signal.
