[Form 4] TETRA Technologies, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Timothy C. Moeller, SVP - Supply Chain & Chemicals at TETRA TECHNOLOGIES INC (TTI), reported equity transactions on 08/25/2025. On that date previously granted restricted stock units (RSUs) vested and converted into common stock: 12,754 RSUs from a 2023 grant and 13,611 RSUs from a 2024 grant were reported as acquired at $0.00. To satisfy tax withholding on those vestings, 3,106 and 3,315 shares were surrendered at $4.49 per share. The filing shows beneficial ownership levels moving through the transactions with reported holdings of 414,342, 411,236, 424,847 and 421,532 shares at different reporting lines. Some portions of the RSU awards remain unvested and will continue vesting semiannually through February 25, 2026 and February 25, 2027.

Insights

Equity Compensation Analyst

TL;DR: Routine RSU vesting and tax withholding by an officer, increasing share count then reducing for taxes.

The Form 4 documents standard equity compensation mechanics: two tranches of RSUs vesting on 08/25/2025 converted one-for-one into common stock and then a portion surrendered to satisfy tax withholding at $4.49 per share. The net effect is a temporary increase in reported beneficial ownership followed by a reduction equal to the shares withheld. Remaining unvested RSUs vest semiannually through early 2026 and 2027, indicating ongoing dilution potential over that schedule. This disclosure is procedural and non-eventful from an operational perspective.

Securities/Insider Trading Specialist

TL;DR: Transactions are routine insider vesting and withholding; no indicative open-market sale activity is reported.

The filing shows no open-market disposals or new purchases; transaction codes indicate vesting (M) and tax withholding (F). Surrenders to cover taxes were executed at $4.49 per share, which is a non-market disposition with no cash proceeds to the reporting person. The pattern is consistent with compliance reporting under Section 16 and bears no immediate implication of insider-driven liquidity events or signaling through market trades.
