Insights

Routine RSU vesting with tax withholding, no open-market trading signal.

The transactions show Elijio V. Serrano, Sr. Vice President & CFO of TETRA TECHNOLOGIES INC, receiving equity through compensation rather than making discretionary market trades. He exercised 137,654 restricted stock units that vested into an equal number of common shares.

Of these, 54,167 shares were surrendered at $8.22 per share to satisfy tax withholding obligations, a mechanistic step coded as an F transaction, not an open-market sale. This left him with 1,635,895 directly held common shares after the filings.

The filing indicates there is no remaining unvested portion of this specific restricted stock unit award, and derivativeSummary is empty, suggesting all units from this grant are now fully vested and converted. Overall, this pattern aligns with standard executive compensation practices and carries limited informational value about Serrano’s view on the stock.
