Tetra Tech Posts Strong Q4 and Fiscal 2026 Results, Backlog Up 13%

what happened

Tetra Tech, a provider of engineering and technical services in water, environment and sustainable infrastructure, published results for the fourth quarter and the fiscal year that ended September 27, 2026, as reported by TradingView. Quarterly revenue reached $1.34 billion, and net revenue after subcontractor costs came in at $1.15 billion. Adjusted EBITDA was $194 million, with the margin up 90 basis points year over year, and adjusted EPS was $0.49, up 9%.

Backlog at the end of the quarter rose 13% to $4.67 billion. The board approved a quarterly dividend of $0.072 per share, an 11% increase, and the company repurchased $100 million of stock in the quarter. For the first quarter of fiscal 2027, Tetra Tech expects EPS of $0.36 to $0.38.

why it matters

The report looks solid: margin expansion and a growing backlog point to sustained demand for the company's services, and the fiscal 2027 outlook gives investors a reference point. A significant share of revenue comes from US government agencies, so Washington's budget decisions remain a key risk for the shares.
