Chairman and CEO Comments

Tetra Tech Chairman and CEO Dan Batrack commented, “Tetra Tech began fiscal 2023 with record high net revenue and earnings as a result of our strong operations where we are Leading with Science^® in the areas of water, environment and sustainable infrastructure. On a year-over-year basis, we saw double-digit top line growth across both our government and commercial end markets. We also had new orders approaching $1 billion in the quarter contributing to an all-time high backlog of $3.81 billion which further improves our outlook for fiscal 2023 and beyond.”

Mr. Batrack further stated, “We are very pleased to announce that we successfully closed the RPS Group transaction at the end of January. The addition of RPS aligns with our strategy to be the premier global high-end consulting and engineering firm addressing the impacts of climate change. RPS brings 5,000 staff that significantly expand our position in U.K. water programs, and add energy transformation expertise in the U.K., Europe and Australia.”

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 included in this release.
