Tetra Tech (TTEK): Navigating Growth Amid Infrastructure Investment Uncertainty

Sands Capital Global Growth Fund recently featured Tetra Tech, Inc. (NASDAQ:TTEK) in its Q2 2026 investor letter. Tetra Tech is a US-based company specializing in water, environment, and sustainable infrastructure services. The investor letter highlights Tetra Tech's market dominance in the water-related engineering and construction design sector, driven by increased US infrastructure and manufacturing investment.

The company's focus on water conservation, weather-related risk, and domestic self-sufficiency contributes to its valuation advantage.

Despite some mixed consulting sector dynamics due to potential AI disruption, Sands Capital maintains a positive outlook on Tetra Tech. They purchased the stock in December 2024, viewing it as a valuation opportunity amidst uncertainty about a potential Trump administration's impact on growth prospects. However, the letter acknowledges that Tetra Tech may share similar trading dynamics to other IT services or government services businesses, which could face terminal value questions due to AI disruption.

The fund's Q2 2026 investor letter also notes that Tetra Tech's shares have returned 2.48% over the past month and 0.56% over the past year, with a market capitalization of $9.19 billion. Sands Capital Global Growth Fund has reduced its holdings of Tetra Tech since the previous quarter, down from 46 to 36 portfolios. While they acknowledge the potential of Tetra Tech as an investment, they believe other AI stocks may offer greater upside potential and less downside risk.

Overall, Sands Capital Global Growth Fund's Q2 2026 investor letter provides a comprehensive overview of Tetra Tech's market position, growth prospects, and valuation considerations within the broader context of AI infrastructure investments.
