Who hires Tetra Tech and which public and private clients form its core market?
Tetra Tech serves public agencies and regulated private firms needing complex water, environmental, and infrastructure engineering; this client mix drives steady, non-discretionary project pipelines supported by rising 2025 federal infrastructure allocations and climate-resilience spending.

Who Makes Up Tetra Tech's Core Customer Base?

Commercial clients and international buyers represent about 57% of 2025 revenue, including Fortune 500 companies in energy, technology, manufacturing, plus national governments and global energy firms after the RPS Group acquisition.
Customer Type and Market Role: Predominantly B2B/B2G Technical Services

Most Commercially Important Segment: Federal Government Contracts
