Polen Global SMID Company Growth stated the following regarding Tetra Tech, Inc. (NASDAQ:TTEK) in its Q3 2024 investor letter:

“We initiated a new position in Tetra Tech, Inc. (NASDAQ:TTEK), an environmental consulting business we’ve followed in our library for several years. Tetra Tech is focused on water and water infrastructure-related consulting and is a significant player in environmental, renewable energy, sustainable infrastructure, and international development. The company has a long history of consistent growth and solid returns on capital. About 30% of the revenue comes from long-term projects from the federal government, another 11% from state and local, and a portion from disaster response and international aid. This provides some ballast to the company’s demand, also driven by commercial projects. Between significant infrastructure spending, the potential for widespread PFAS cleanup PFAS (per-and poly-fluoroalkyl substances are a large group of man-made chemicals used in various industrial and consumer products since the 1950s), water scarcity, and changing environmental conditions, we believe the demand backdrop for Tetra Tech is improving, creating an attractive investment opportunity”.
