BOSTON and HATBORO, Pa., Sept. 24, 2026 /PRNewswire/ — RS2 Healthcare Partners, a Boston-based private equity firm, announced today the completion of an investment in KMM Group (“KMM” or the “Company”). Headquartered in Hatboro, Pennsylvania, KMM is a vertically integrated precision contract manufacturer specializing in complex, tight-tolerance components for the medical device industry and other highly demanding markets.

“KMM is an exceptional company, with an excellent reputation in the marketplace, highly specialized capabilities, a blue-chip customer base, and an extremely dedicated group of employees,” said Craig Stern, Co-Managing Partner at RS2 Healthcare Partners. “We are thrilled to partner with the founders, John Shegda and Eric Wilhelm, and the new CEO, Mark King, for the Company’s next chapter.”

KMM represents the first new platform investment by RS2 Healthcare Partners, following the Firm’s decision earlier this year to rebrand and focus exclusively on healthcare investing in the lower middle market. “The Company is a differentiated, founder-owned business operating in a sector that we have targeted for many years and where we have significant experience and deep relationships,” said Patrick Furlong, Partner at RS2 Healthcare Partners.  “It is a perfect fit for RS2.”   

In conjunction with the investment, RS2 announced the appointment of J. Mark King as President and Chief Executive Officer of KMM. Mr. King is an industry veteran with more than 30 years of experience in the medical device industry. Previously, he served as President and Chief Executive Officer of Tegra Medical, a leading medical device contract manufacturer and former portfolio company of RS2 Healthcare Partners.  

“I am honored and excited to continue building on KMM’s momentum. I have a long history of working with the principals of RS2 Healthcare Partners as well as serving as an advisor to KMM,” said J. Mark King. “With this investment, I look forward to partnering with RS2, John, Eric, and the rest of the KMM team to expand the Company’s capabilities and further strengthen its position as a premier contract manufacturer for medtech and other end markets.”

“Manufacturing is evolving rapidly, and our customers continue to push the boundaries of engineering,” said John Shegda, Co-founder of KMM. “After considering a number of alternatives, Eric and I chose to partner with RS2 because of their experience, relationships, and values. Partnering with RS2 will help us achieve our vision, uphold our mission, and continue to support our customers.”

Eric Wilhelm, Co-founder of KMM, added, “As we continue to grow, our priority is to strengthen every part of our operation while preserving the culture, accountability, and manufacturing excellence that have always defined KMM. RS2 is the ideal partner for KMM, given the Firm’s significant contract manufacturing expertise and deep experience scaling founder-owned companies.”

Mr. Shegda will serve as Chief Technology Officer, leading engineering and technology strategy, while Mr. Wilhelm has been appointed Executive Vice President, Business Transformation & Organizational Capability, overseeing operational excellence and scalable growth.
