Houlihan Lokey Advises Graham Partners

Houlihan Lokey is pleased to share that Graham Partners (Graham), a private investment firm targeting advanced manufacturing and technology-enabled services businesses, has acquired Midwest Products & Engineering (MPE), a portfolio company of Beecken Petty O’Keefe & Company (BPOC).

Headquartered in Milwaukee, Wisconsin, MPE is a contract development and manufacturing organization (CDMO) that primarily partners with medical device companies to design, engineer, and integrate electromechanical systems used in robotic‑assisted surgery, surgical navigation, cardiology, imaging, and electrosurgical applications. Graham believes the company is benefiting from an industry-wide shift toward outsourcing as medical device companies focus on accelerating speed to market, reducing internal manufacturing complexity, and prioritizing R&D, sales, and marketing competencies. Further, MPE is positioned to benefit from growth in minimally invasive surgeries and an aging global population, which are driving incremental demand for medical device manufacturing partners like MPE that aid in delivering high-quality, cost-efficient solutions.

Over the 40+ years since its founding, MPE has evolved into a vertically integrated CDMO, partnering with customers from the initial design through full-scale manufacturing, assembly, and distribution. Today, MPE‑supported systems help surgeons deliver more precise, less invasive care, from real‑time 3D surgical navigation platforms to noninvasive technologies used to treat tumors without surgery. Graham will seek to accelerate growth at MPE by investing in and helping advance engineering, sales, and operational initiatives at the company, continuing to support MPE’s existing operating model and customer relationships. With existing medical contract manufacturing investments in current portfolio companies, Smithstown and Velosity, and its prior investment in Medbio, Graham intends to leverage its medtech expertise and deep industry advisor network to support MPE’s continued growth.

This transaction further strengthens and highlights Houlihan Lokey’s continued leadership in the medical device outsourcing industry. Houlihan Lokey’s Healthcare Group is among the largest dedicated healthcare investment banking groups in the world. According to LSEG, in 2025, the group closed 35 transactions in the U.S. and was ranked as the No. 1 advisor for all global healthcare M&A transactions.*
