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."

Non-GAAP Financial Measures

To supplement the financial results presented in accordance with generally accepted accounting principles in the United States ("GAAP"), we present certain non-GAAP financial measures within the meaning of Regulation G under the Securities Exchange Act of 1934, as amended. We provide these non-GAAP financial measures because we believe they provide a valuable perspective on our financial results. However, non-GAAP measures have limitations as 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 Tech to those used by our peer companies. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP financial measures is set forth above in this release.
