Tetra Tech Inc: what insiders have been doing
Tetra Tech Inc, founded in 1966, is a Technology company based in Pasadena, United States. Its directors and officers file their transactions with SEC (Form 4). In the past year (20 October 2025 to 20 October 2026), 30 filings came from 12 insiders.
The record shows 1 purchase on the open market worth €43k, made by 1 insider, against 1 sale worth €340k by 1 insider. Taken together, the sales exceed the purchases by €297k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. Among those who bought: 1 senior executive. The largest single trade was a sale of €340k by Carter Brian N, published on 6 February 2026.
The most recent open-market purchase was published on 15 May 2026, 159 days ago. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4.
For context, the typical company on the same exchange (median of 5,453 companies) published 22 filings over the same period, against 30 filings here. Over the whole record (from 2016), the tally stands at 1 purchase and 216 sales. On the fundamentals side, the SEC filing (10-K) for the period ending 28 September 2025 lists revenue at 5.44 bn USD and net income at 247.9 m USD; the dividend was 0.25 USD per share.

From a competitive standpoint, Tetra Tech benefits from deep domain expertise, a global delivery footprint, and exposure to long-term structural demand drivers such as water network renewal, climate adaptation, environmental compliance, critical infrastructure upgrades, and public-asset modernization. The company is widely recognized as a leader in water and environmental consulting, and its ability to combine engineering, science, project execution, and technology-enabled solutions strengthens its differentiation versus more generalist peers.
Geographically, Tetra Tech has an international presence across the United States, North America, Europe, the Middle East, Asia-Pacific, and selected development markets. Recent company updates point to solid commercial momentum, supported by demand from municipal water clients, defense customers, energy projects, and power-transmission work. Recent milestones include major contract awards from U.S. government agencies, targeted acquisitions, leadership changes, and increased fiscal 2026 guidance. For investors, the key appeal is the combination of recurring infrastructure demand, policy-linked spending, and exposure to sustainability-driven capital allocation themes, all within a publicly listed U.S. company trading on NASDAQ.
