Tetra Technologies (TTI) SVP Roy McNiven Converts RSUs, Sells Shares

What Happened

Roy McNiven, Senior Vice President of Tetra Technologies (TTI), had restricted stock units (RSUs) vest on Feb 25, 2026. A total of 26,366 shares converted from RSUs into common stock (12,754 + 13,612). To cover tax withholding, 10,936 shares (5,019 + 5,917) were surrendered to the company at an effective price of $11.14 per share, generating cash value of $121,827 ($55,912 + $65,915). The remaining shares were issued to McNiven. This was a vesting/conversion of RSUs with share-withholding for taxes (not an open-market sale or cash purchase).

Context

This was a routine RSU vesting event with a sell-to-cover (share surrender for tax withholding), which is common and does not by itself indicate a change in insider sentiment. These transactions differ from open-market sales or cash exercises of stock options: here RSUs simply converted into shares and a portion was used to satisfy withholding tax obligations.
