Summary
True Environmental, Inc. ("True"), backed by Halle Capital, has announced that Sikumiut Environmental Management Limited ("SEM") has joined its platform, according to a Business Wire release. SEM is a multidisciplinary environmental and technical services firm headquartered in St. John's, with an office in Labrador City, serving mining, utility, and energy clients across Newfoundland and Labrador. Its services include environmental consulting, geomatics and GIS, digital solutions, stakeholder engagement, and technical staffing and recruitment. The firm is registered as an Inuit Business with the Nunatsiavut Government.

The transaction extends True's footprint into Atlantic Canada. Together with Ensero Solutions, True's mining- and water-focused company operating in Western and Northern Canada, SEM gives True a coast-to-coast Canadian presence. The release does not disclose the purchase price or other financial terms.

True describes itself as a platform for founder- and employee-owned environmental consulting and engineering firms, providing capital and management support to accelerate growth and facilitate ownership transitions. The platform is led by CEO Jim Stamatis, former CEO of Louis Berger, who has more than 30 years of industry experience. Halle Capital, a New York-based lower-middle-market growth private equity firm, describes its strategy as thematic investing in essential services industries with high fragmentation and durable secular tailwinds.

SEM President Grant Vivian said joining True is "an investment in our people and in the future of what we can deliver for our clients," adding that the firm gains expanded resources and broader capabilities without sacrificing its culture or client focus. Stamatis praised SEM's technical strength and client relationships and cited Grant Vivian, Stefan Cahill, Stephen Rowe, and the broader SEM team. He said the firm "is exactly the kind of firm we seek to partner with."
