Ritrievi Kimberly E 4

What Happened
Kimberly E. Ritrievi, a director of Tetra Tech, reported receipt of a 25,883-share restricted stock unit (RSU) award and the exercise/conversion of multiple derivative awards on March 16, 2026. The filing shows conversions/exercises of a total of 20,968 shares (various lots) at an exercise price of $0.00 that were also reported as disposed on the same date. Net result reported in this filing: +25,883 shares from the RSU award/settlement. Footnotes indicate certain performance stock units (PSUs) vested earlier, were deferred under the company’s deferred compensation plan, and were settled upon retirement.

Key Details

• Transaction date: 2026-03-16. All transactions reported at $0.00 per share.
• Quantities: 25,883 RSUs granted/settled (A); 20,968 shares exercised/converted (M) and simultaneously reported as disposed (M). Net increase = 25,883 shares.
• Shares owned after transaction: not specified in the provided filing.
• Notable footnotes: F1 explains PSUs vested between 11/23/2021 and 11/18/2025 and were deferred/settled on retirement; F2–F4 describe RSU award and vesting/exercisability terms; F5–F8 note prior 5-for-1 forward stock split adjustments.
• Filing timeliness: not indicated in the provided data.

Context

• Code meanings: A = award/grant (RSUs); M = exercise or conversion of a derivative. Converting/exercising means turning previously granted PSUs/options into common shares; the same-date “disposed” entries indicate those converted shares were reported as transferred or sold on the same day.
• Interpretation for investors: This filing reflects a settlement/award event (including deferred PSU settlement upon retirement) rather than a straightforward open-market purchase or routine sale by the insider. It’s factual reporting of compensation/settlement activity — it should not be taken alone as a direct bullish or bearish signal.
