Precision Concepts International (PCI), a portfolio company of The Sterling Group, has acquired Comar in a move that creates one of North America’s most diversified rigid packaging platforms serving both consumer and healthcare markets.
Headquartered in Huntersville, North Carolina, PCI provides specialty rigid packaging solutions to brand owners in personal care, household, and food and beverage sectors. Comar, founded in 1949, manufactures rigid packaging and plastic medical products across its facilities in the United States, Puerto Rico, and Ireland.
“The combination of PCI and Comar creates a powerful partnership that enhances our capabilities to provide industry-leading rigid packaging solutions and exceptional service,” said Ray Grupinski, CEO of Precision Concepts. “The acquisition enables PCI to offer an even broader range of products and services to deliver more value to our customers.”
Ken Swanson, Chairman of Precision Concepts, added that “partnering with Comar will further accelerate the growth of the PCI platform. The combined company will benefit from enhanced geographic, customer, and end market diversification, and the acquisition marks an important step forward in our mission to build a specialty packaging leader.”
The Sterling Group, a Houston-based private equity and private credit investment firm with around $9 billion in assets under management, acquired PCI in July 2025. Sterling has a long record of investing in and growing packaging companies. “With so many sponsor-backed businesses in the sector, the coming months will be a story of who can rise above the crop,” the firm said, noting that despite recent market headwinds, it remains active and “bullish” on the packaging industry.
Evercore acted as financial advisor and Latham & Watkins LLP as legal advisor to PCI. Guggenheim Securities, LLC and Jones Day LLP advised Comar.
