Board of Directors approved an additional $500 million share repurchase authorization. This more than doubles the amount remaining under the Company’s existing share repurchase program at the end of the third quarter of fiscal 2026, increasing total available share repurchases to $898 million.

For the twelve months ended the third quarter of fiscal 2026, Tetra Tech generated $567 million in cash flow from operations and returned $322 million to shareholders through share repurchases and dividends. During this period, the Company also advanced its Leading with Science® differentiation with the completion of strategic acquisitions that added new clients and technical capabilities. The strong cash flow also enabled the Company to continue deleveraging its balance sheet, and its net debt leverage ratio was 0.88x at the end of third quarter 2026.

"The increased share repurchase program reflects confidence in Tetra Tech’s long-term growth outlook and our balanced approach to capital allocation," said Roger Argus, Tetra Tech Chief Executive Officer. "Our more than 20-year track record of generating cash from operations in excess of net income enables us to continue investing in organic growth initiatives and strategic acquisitions, while the new authorization expands our capacity to return capital to shareholders."
