Tetra Tech — Nov 12, 2025 release

The fiscal 2026 guidance for net revenue projects a range of 5% to 11% year-over-year growth, excluding fiscal 2025 USAID / DOS and episodic disaster recovery activities. For the first quarter of fiscal 2026, Tetra Tech expects net revenue to range from $950 million to $1.0 billion and EPS to range from $0.30 to $0.33.     2 Reconciliation of the net revenue guidance to the most directly comparable GAAP measure is not available without unreasonable efforts because the Company cannot predict the magnitude and timing of all the components, including subcontractor costs, required to provide such reconciliation with sufficient precision.   2     Webcast   Investors will have the opportunity to access a live audio-visual webcast and supplemental financial information concerning the fourth quarter of fiscal 2025 results through a link posted on the Company’s website at tetratech.com on November 13, 2025, at 8:00 a.m. (PT).   Reconciliation of GAAP and Non-GAAP Items   In thousands (except EPS data)       Three Months Ended     Fiscal Year Ended       Sep. 28, 2025     Sep. 29, 2024     Sep. 28, 2025     Sep. 29, 2024   Revenue   $ 1,330,100     $ 1,374,474     $ 5,442,590     $ 5,198,679   USAID / DOS     (97,771 )     (215,267 )     (650,344 )     (793,029 ) Revenue excl.
