Chairman and CEO Comments

Tetra Tech Chairman and CEO, Dan Batrack, commented, “As we completed fiscal year 2023, our differentiated Leading with Science^® approach to the water, environment and sustainable infrastructure markets generated the highest financial results of any quarter and year in our history. In addition to our all-time high results in revenue, earnings and backlog, we accomplished significant strategic milestones this year, including closing the largest transaction in our history, enhancing our capital structure, and expanding our Tetra Tech Delta technologies to include a subscription software practice.

“Our clients are continuing to increase funding for water and environmental programs, including climate change mitigation and adaptation to address water security, coastal flooding, energy transition and biodiversity protection. With our market leadership in these key areas, we booked nearly $2 billion in new orders in the fourth quarter and increased our backlog by more than $1 billion over last year. Building on this momentum, we expect double-digit revenue growth in fiscal 2024 and further margin expansion.”

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.
