Tetra Tech plans to release its first quarter 2026 financial results on Wednesday, January 28, 2026, immediately following market close. The company will host a live audio-visual webcast and conference call on Thursday, January 29, 2026, at 8:00 a.m. Pacific Time to discuss revenue performance, segment margins, backlog trends and guidance for full-year 2026. Investors can access the webcast via the investor relations section of tetratech.com, with a replay available after the call. Management indicated that order intake in the water and environment segment grew by mid-single digits year-over-year in Q1, while sustainable infrastructure projects remained on track to deliver margin expansion.

Effective February 19, 2026, Roger Argus will assume the role of Chief Executive Officer concurrent with Tetra Tech’s annual meeting of shareholders, while current Chairman and CEO Dan Batrack will transition to Executive Chairman for at least two years. Argus, a 30-year veteran who currently serves as President, led the company’s expansion into Europe and Asia through six strategic acquisitions and oversaw integration of emerging technologies in water resource management. Under Batrack’s 20-year tenure as CEO, Tetra Tech grew from a U.S.-centric firm to a global engineering leader with approximately $5 billion in annual revenue and more than 25,000 employees. The board cited rigorous succession planning and continuity of strategy as key drivers for the transition, positioning Tetra Tech for sustained global growth.
