Fiscal 2026 results test raised guidance • 2026-11-30

Base target: $36 / p=50% prob

Biggest risk

Backlog timing, project margins and federal spending could disappoint. The company's 8% year-over-year Q3 net-revenue growth measure excludes USAID/DOS and episodic disaster-response work, making the unadjusted demand picture important to monitor. No verified post-Q3 analyst estimate or target revisions were available. [#SEC-8K-2026-07-29]

Invalidation

Break below $27 or thesis failure.

What would change my mind?

The Q3 backlog increase, higher FY26 guidance and strong operating cash flow support a cautiously positive view if awards convert at attractive margins. Q3 operating cash flow was $229 million; management attributed growth chiefly to U.S. federal and international markets. [#SEC-8K-2026-07-29]

Commentary

Primary-source operating evidence is constructive, but the packet's recent-news items concern other issuers and do not establish TTEK news tone. No reliable immediate post-Q3 price reaction, social coverage, options data, short-interest figure or post-print analyst revisions were provided; the zero sentiment fields denote unavailable measurements, not neutral observations. The September 28 anchor is too late to isolate the July earnings reaction. Catalyst probabilities and price moves are estimates.

Fiscal 2026 results test raised guidance
After fiscal Q3 net revenue of $1.11 billion, EPS of $0.42 and backlog of $4.49 billion, Tetra Tech raised FY26 adjusted EPS guidance to $1.56–$1.59 and increased the midpoint of its net-revenue range to $4.315–$4.365 billion. The year-end report will test whether Q4 meets management's $1.12–$1.17 billion net-revenue and $0.45–$0.48 EPS outlook. The expected date is an estimate, not an announced reporting date. [#SEC-8K-2026-07-29]
Prob 70.00% • Move 8.00% • Priced-in 55.00%

Short-term Catalysts

Next few weeks

Expanded repurchase authorization
2026-12-31
The board authorized a $500 million increase to the share-repurchase program on September 10. This adds capacity but does not establish how much or when Tetra Tech will buy; subsequent execution and cash generation matter. The monitoring date is an estimate. [#8-K-2026-09-10]

Long-term Catalysts

Months to a year

Backlog conversion across water, federal and digital projects
2027-06-30
Q3 backlog rose 5% sequentially to $4.49 billion. The company identified water-infrastructure, environmental, federal and data-center power-system wins, but awards and framework positions do not guarantee near-term revenue. Conversion into profitable net revenue is the key monitoring point; the date is an estimate. [#SEC-8K-2026-07-29]
Prob 65% • Move 10% • Priced-in 45%

Risks

A repurchase authorization is discretionary and is not a commitment to purchase shares. [#8-K-2026-09-10]
A slower conversion of the $4.49 billion Q3 backlog could weaken revenue or margins. [#SEC-8K-2026-07-29]
The Q3 growth comparison excludes USAID/DOS and episodic disaster-response work; weakness in those activities could obscure underlying progress. [#SEC-8K-2026-07-29]
The raised FY26 outlook leaves execution risk against Q4 net-revenue and EPS ranges. [#SEC-8K-2026-07-29]

Peers

Symbol	Summary
ACM	AECOM is a relatively direct infrastructure-design peer with water and environmental exposure. Its reported backlog growth offers an industry comparison, though project mix and backlog definitions require care. AECOM fiscal Q3 release
BAH	Booz Allen is an adjacent comparison for government-contract cadence, not a close match for Tetra Tech's water and environmental engineering mix.
J	Jacobs is a relatively direct technical-services peer across water, environmental and infrastructure work, but its larger scale and broader portfolio limit valuation read-through. Jacobs investor overview
