Key Points

Fourth quarter net revenue increased 5% year over year to $1.15 billion.
Management expects 10% U.S. commercial revenue growth in fiscal 2027.
On its fourth quarter of 2026 earnings call, held on Nov. 12, 2026, Tetra Tech (NASDAQ:TTEK) reported record operating income and earnings per share for fiscal 2026. The company's strategic emphasis on high-end water and environmental engineering expanded operating profit margins across its global operations. Three takeaways from management's call stand out for long-term investors.
1. Funded Backlog Reaches $4.7 Billion to Fuel Multiyear Revenue
Tetra Tech finished fiscal 2026 with $4.7 billion in funded backlog, which represents customer projects that are fully contracted and authorized to begin work immediately. Broad-based order momentum across federal, municipal, and commercial markets yielded three consecutive quarters with a book-to-bill ratio, which measures new orders against billed revenue, above 1.1 times. That order volume gives the company strong multiyear revenue visibility across its global engineering operations.
And perhaps most importantly, we ended the year with $4.7 billion in funded backlog up 13% from last year.
-- Roger Argus, Chief Executive Officer and President
2. Technical Design Focus Expands Operating Margins
Management prioritizes specialized front-end technical design and engineering for water and environmental projects because complex consulting services command premium pricing. That strategic focus expanded profit margins across both government and commercial client segments in fiscal 2026. Higher-margin work supports Tetra Tech's long-term goal to increase its earnings before interest, taxes, depreciation, and amortization, known as EBITDA, margin by half a percentage point annually.
These results further support our long-term strategic goals to improving EBITDA margins by an average of 50 basis points annually.
-- Steve Burdick, Chief Financial Officer
3. Commercial Water and Digital Automation Drive 10% Market Growth
Industrial clients in advanced manufacturing, mining, and data centers are expanding their investments with Tetra Tech to optimize water recycling and automate facility operations. Modernizing operational controls also addresses growing cybersecurity requirements for critical infrastructure assets. Management projects 10% revenue growth in the U.S. commercial segment for fiscal 2027 as demand for high-end water treatment and digital solutions accelerates.
For U.S. commercial, we expect to see approximately 10% growth driven by increased demand for our advanced water and associated digital automation solutions that address the needs for water-intensive advanced manufacturing data centers and mining.
-- Roger Argus, Chief Executive Officer and President
Looking Ahead
Backlog growth of 13% gives Tetra Tech a solid operational foundation as federal and local clients navigate policy transitions. Demand for clean water infrastructure and automated facility upgrades continues to accelerate across global markets.
We finished a strong fourth quarter with backlog up 13% from last year, giving us a solid foundation for fiscal 2027.
-- Roger Argus, Chief Executive Officer and President
Long-standing client relationships and deep technical expertise position the business to capture shifting government funding priorities. Tetra Tech relies on broad contract capacity and specialized engineering skills to maintain its competitive moat in water and environmental consulting.
Our technical depth, long-standing client relationships and existing contract vehicles allow us to respond as priorities change.
