Tetra Tech, Inc, a US-based consulting and engineering firm, has announced it will acquire SAGE Group Holdings Ltd, an Australian automation solutions provider, to strengthen its position in digital systems and automation services.
The agreement, signed on 1 May 2025, marks a strategic move for Tetra Tech as it seeks to expand its capabilities in sectors including municipal water, energy, manufacturing, transportation, and defence.
Based in Pasadena, California, Tetra Tech is known for its work in water, environment, and sustainable infrastructure.
The acquisition of SAGE Group is expected to bolster Tetra Tech’s portfolio by integrating SAGE’s expertise in smart infrastructure, engineered control systems, and digital automation — areas increasingly critical to industrial and government clients seeking to optimise operational efficiency through technology.
“SAGE Group’s digital automation capabilities will further enhance our offerings by bringing additional expertise, AI-enabled technology, and demonstrated client solutions to our collective team,” said Dan Batrack, Chairman and CEO of Tetra Tech.
He added that the move aligns with the company’s broader strategy of helping clients make data-driven decisions through advanced technology.
SAGE Group, headquartered in Australia, provides a range of automation services, including cloud integration, cybersecurity, and electrical and instrumentation design.
Commenting on the agreement, Adrian Fahey, Managing Director of SAGE Group, said the partnership reflects a “strong cultural fit” and shared vision between the two companies.
“This partnership will position SAGE for long-term growth, broaden its service offering, and provide new global resources — enhancing the value, innovation, and support we deliver to our clients and expanded opportunities for our employees,” Fahey said.
Following the completion of the transaction, SAGE Group will join Tetra Tech’s Commercial International Business Group. The acquisition is subject to customary closing conditions.
