SERRANO ELIJIO V 4

What Happened
Elijio V. Serrano, Senior Vice President & CFO of TETRA TECHNOLOGIES, had restricted stock units (RSUs) vest on February 25, 2026. A total of 41,421 RSUs converted into common shares (21,256 from the 2023 grant and 20,165 from the 2024 grant). To satisfy tax withholding, 10,614 shares were surrendered to the company (5,703 and 4,911 shares, respectively) at $11.14 per share, totaling about $118,240. The conversions are recorded as derivative-to-common stock transactions (acquired at $0), and the surrender for taxes is recorded as a disposition.

Context
This was not an open-market sale—Serrano received shares through RSU vesting and the company withheld a portion of those shares to cover taxes (a common cashless-withholding settlement). The filing shows receipt of equity (informationally bullish) while the retained-withholding is routine and does not indicate an independent decision to sell shares on the market.
