Tetra Tech Benefited From CIG Growth Offset by GSG

Revenues from U.S. federal customers, accounting for 20% of the quarter’s net revenues, increased 12% year over year, excluding USAID, Department of State and episodic disaster-response activities. Growth was supported by higher activity with the Navy and U.S. Army Corps of Engineers. U.S. commercial revenues, representing 20% of the total, rose 1% as gains in power transmission offset lower renewable-energy activity.

U.S. state and local revenues, accounting for 13% of net revenues, increased 5% year over year, driven by strength in municipal water treatment, partly offset by lower flood-protection work. International revenues, representing 47% of the total, advanced 12% on growth in U.K. water and digital water automation programs.

Tetra Tech reports revenues under the segments discussed below:

The Commercial/International Services Group delivered net revenues of $634.2 million, up 9.3% year over year. Government Services Group net revenues were $474.3 million, down 17.2% from the prior-year quarter on a reported basis. Excluding USAID, Department of State and episodic disaster-response activities, GSG net revenues increased 7%, reflecting strength in water infrastructure and defense programs.
