On November 10, 2025, Tetra Tech’s Board of Directors approved the Company’s 46^th^ consecutive quarterly dividend at an amount of $0.065 per share, a 12% increase year-over-year, payable on December 12, 2025, to stockholders of record as of December 1, 2025. In the fourth quarter, Tetra Tech repurchased $50 million of common stock. Additionally, as of September 28, 2025, the Company had $598 million remaining under the approved share repurchase programs.

Executive Management Comments

Dan Batrack, Chairman and CEO, commented, “We finished fiscal 2025 with another strong quarter resulting in record net revenue, record operating income, and significant operating margin expansion. These all-time high results were driven by the continued strong demand for our differentiated high-end consulting services in resilient water management and digital water automation. Our strategy focused on essential water and environmental services has allowed us to successfully navigate the recent changes in U.S. federal government priorities as we achieved record financial performance for 2025.”

Roger Argus, President, stated, “Looking forward to fiscal 2026 and beyond, we see increased demand for our high-end services to address the development of water-reliant infrastructure, including data centers and industrial manufacturing. Our high-voltage engineering practice has benefited from these projects with its backlog doubling in the fourth quarter. In addition, our front-end consulting services are critical to the expansion and protection of coastal and marine infrastructure for defense clients around the world.”

Business Outlook

The following statements are based on current expectations. These statements are forward-looking, and the actual results could differ materially. These statements do not include the potential impact of transactions that may be completed or developments that become evident after the date of this release. The Business Outlook section should be read in conjunction with the information on forward-looking statements at the end of this release.

For fiscal 2026, Tetra Tech expects net revenue^2^ to range from $4.05 billion to $4.25 billion and EPS guidance to range from $1.40 to $1.55. 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<br>without unreasonable efforts because the Company cannot predict the magnitude and timing of all the components, including subcontractor<br>costs, required to provide such reconciliation with sufficient precision.

Non-GAAP Financial Measures

To supplement the financial results presentedin accordance with generally accepted accounting principles in the United States (“GAAP”), we present certain non-GAAP financialmeasures within the meaning of Regulation G under the Securities Exchange Act of 1934, as amended. We provide these non-GAAP financialmeasures because we believe they provide a valuable perspective on our financial results. However, non-GAAP measures have limitationsas analytical tools and should not be considered in isolation and are not in accordance with, or a substitute for, GAAP measures. In addition,other companies may define non-GAAP measures differently which limits the ability of investors to compare non-GAAP measures of Tetra Techto those used by our peer companies. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financialmeasures is set forth above in this release.
