What Tetra Tech does

Tetra Tech is a global consulting and engineering firm founded in 1966 and headquartered in Pasadena, California, publicly traded on NASDAQ under ticker TTEK with a market capitalization of approximately $8.83 billion. The company employs more than 25,000 people across 500 offices in 125 countries and organizes operations into two segments: a Government Services Group (GSG) serving U.S. federal, state, and municipal agencies through vehicles such as OASIS+, Alliant 3, SeaPort-NxG, and MDA SHIELD, and a Commercial/International Group (CIG) serving water utilities, mining and energy companies, and international government clients across water, environment, energy, and sustainable infrastructure. Annual revenue is approximately $5 billion with record backlog of $5.1 billion as of Q2 FY2025, and FY2026 guidance was raised to $4.25–$4.40 billion.

The firm's core technology platform is Tetra Tech Delta, a suite of nine proprietary AI-powered products including FusionMap (AI geospatial asset management), OceansMap (600+ environmental data sources), WaterNet (SaaS water network management), Volans (3D airspace visualization), Neptune AI (96%-accurate marine mammal acoustic detection), myProjects (cloud project management supporting $26B in project value), HydroWeb (infrastructure intelligence with digital twins), InfraVue360 (asset management), and RailAI (autonomous rail inspection at 70 mph). The company makes money primarily through professional services engagements priced on a project- and contract-specific basis, including long-term task orders under IDIQ vehicles and multi-year framework agreements (e.g., Scotland Excel, AMP8 water utility commitments), with the Delta products increasingly embedded into these engagements.

Recent strategic activity centers on inorganic expansion and digital capability deepening. Between 2022 and 2026 Tetra Tech completed acquisitions of RPS Group (UK water), TIGA, Axiom Data Science, Piteau Associates, LS Technologies, Convergence Controls & Engineering, Carron + Walsh, SAGE Automation, Halvik Corp (adding ~600 federal IT and analytics staff), and Providence Consulting Group (Australian defense advisory), while signing a nuclear energy MOU with Westinghouse and transitioning leadership to Roger Argus as CEO in February 2026 with Dan Batrack moving to Executive Chairman.
