"Finding a partner who shared our values and long-term vision while bringing operational expertise was crucial," said Hilgert, who will maintain his position as CEO and retain significant ownership in the business. "Pike Street Capital is exactly that partner."

The investment comes at a time when demand for sophisticated air handling systems is surging, driven by increasing focus on efficiency and air quality across industries. Superior Duct operates from five strategic locations, including its Pomona, California headquarters, with additional facilities in Camarillo, Las Vegas, Phoenix, and a recently launched operation in Columbus, Ohio.

Dave Dandel, Partner at Pike Street Capital, expressed enthusiasm about the partnership's potential:

"They've built a high-performing organization with a strong reputation in the industry, and we see a great opportunity to build on that foundation," he said.

The private equity firm has outlined an ambitious growth strategy, planning significant investments in various areas including:

• Product development initiatives
• Safety and productivity enhancements
• New facility expansions
• Geographic market expansion
• Strategic acquisitions
• Workforce development

This investment represents a significant development in the sheet metal fabrication sector, as private equity continues to show interest in industrial technology companies that serve critical infrastructure needs. The partnership is expected to accelerate Superior Duct's expansion beyond its current Western U.S. stronghold, particularly in markets driven by the growing semiconductor and data center industries.
