Green Bay, Wis. / Marquette, Mich. (February 27, 2026) – Tweet Garot Mechanical, a 127-year-old mechanical contracting firm, has acquired Prime Specialty Contracting, a full-service mechanical, plumbing, HVAC, and custom metal fabrication contractor with offices in Marquette and Escanaba, Michigan. The acquisition establishes Tweet Garot as the leading mechanical contractor in Michigan’s Upper Peninsula and strengthens the company’s growing statewide presence.
“I’ve known Prime’s founder Cory Bushong for many years, and I’ve watched him build something truly unique,” stated Tweet Garot Chairman and CEO, Christopher Howald. “In just six years, Cory and his team have built a business and a culture that stand out in this industry. We didn’t pursue Prime because of geography alone — we pursued them because of the people, the reputation, and the values they’ve established. Together, we believe we can create the dominant destination for both employees and customers in Upper Michigan.”
Prime Specialty Contracting operates through three divisions — Prime Mechanical Contracting, Prime Plumbing, Heating & Cooling, and Prime Welding & Fabrication — serving residential, commercial, and industrial clients throughout the Upper Peninsula. Both the Marquette and Escanaba facilities will remain open and in full operation. Bushong will remain with the company permanently, continuing to lead his team of approximately 90 employees.
“When I started Prime in 2019, the goal was always to build something our team and community could be proud of,” stated Bushong. “Partnering with Tweet Garot gives us the resources, technology, and scale to take that vision even further — without changing what makes us who we are. I’m excited for what this means for our employees, our customers, and the Upper Peninsula.”
Tweet Garot President and COO Hope Voigt added, “The synergies between our organizations are natural. We share the same commitment to culture, employee development, and customer relationships. With Prime’s deep roots in the UP and Tweet Garot’s resources and technology platform, we’re positioned to offer something no one else in the region can match.” The acquisition closed in February 2026. Terms of the deal were not disclosed.
