Tetra Tech has a four-quarter earnings beat streak with a 10.7% average surprise and an attractive forward P/E of 16.3x with a PEG near zero, but a death cross with negative 3.7% moving average slope and declining revenue signal that the near-term technical environment requires patience before entry.

About Tetra Tech, Inc.
About Tetra Tech, Inc.
Tetra Tech ended fiscal 2025 with a $4.1 billion backlog and more than 25,000 associates delivering water, environment, and sustainable infrastructure services on over 100,000 projects across more than 100 countries. Revenue splits between its Government Services Group (GSG, 49.1% of fiscal 2025 revenue), which serves U.S. federal, state, and local clients, and its Commercial/International Services Group (CIG, 52.3%), which serves U.S. commercial and international clients. International clients, primarily in Australia, Canada, and the United Kingdom, contributed 37.4% of fiscal 2025 revenue.
The revenue model combines fixed-price (43.5% of fiscal 2025 revenue), time-and-materials (42.6%), and cost-plus (13.9%) contracts, with revenue recognized on a percentage-of-completion basis across project lifecycles. U.S. federal clients represented 31.6% of revenue, with the Department of Defense at 11.6% and USAID at 10.6% each individually exceeding 10% of total revenue in fiscal 2025. Tetra Tech supports a broad range of client missions including water treatment and distribution, environmental remediation, disaster recovery, and infrastructure engineering, and has been ranked No. 1 in water treatment and desalination by Engineering News-Record for 12 consecutive years. The company differentiates through its Tetra Tech Delta suite of proprietary analytics and AI-enabled tools for infrastructure assessment, spatial data interpretation, and water system optimization. Competition is fragmented, spanning large national engineering firms and specialized regional consultants.

Government-contract concentration is the most directly quantified risk in the filing: U.S. federal contracts are terminable at the government's discretion without cause, and annual appropriations cycles create visibility gaps between backlog and realized revenue. USAID accounted for 10.6% of fiscal 2025 revenue, down from 13.0% in fiscal 2024, a decline that may reflect shifting foreign aid priorities; further reductions could create a meaningful revenue gap given the agency's historical share. DoD concentration at 11.6% of fiscal 2025 revenue carries different dynamics — defense budgets are more stable than foreign aid appropriations — but remains subject to program delays and authorization risk. In March 2026, Tetra Tech appointed Eric Thornburg, former CEO of H2O America (SJW Group) from 2017 to 2025, to its Board of Directors.
