Executive Management Comments

Dan Batrack, Chairman and CEO, commented, “Tetra Tech began fiscal 2024 with a strong first quarter as revenue was up in all of our key end markets, building on our record performance of the prior year. Based on the strength of our end markets, our strong results in the first quarter, and the increasing realization of revenue synergies with RPS, we have raised our full year guidance for both net revenue and EPS, with a forecasted 20% growth in EPS for fiscal 2024.”

Steve Burdick, Chief Financial Officer, said, “In addition to our record first quarter revenue and earnings, we continue to generate strong positive operating cash flow with $353 million over the trailing twelve months, which is 152% of net income for the same period. This annual cash generation continues our track record of cash flow exceeding net income every year for the last two decades.”

Jill Hudkins, President, stated, “These results demonstrate the value of Tetra Tech’s pure play focus on the water cycle that continues to drive increasing demand for our high-end services. Tetra Tech’s key differentiator is our Leading with Science^® approach to the water cycle; from client-funded research and development, watershed management, water supply and treatment, to flood protection and marine navigation.”

Our goal is to improve the lives of one billion people around the world by 2030, providing sustainable solutions across our water and environment markets by optimizing water management, preserving biodiversity, and mitigating climate change.”

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.
