Monomoy Capital Partners Announces Exit of Shaw Development

New York, New York, October 31, 2023 – Monomoy Capital Partners, a private investment firm focused on private equity and credit investing in the middle market, is pleased to announce the sale of Shaw Development to Madison Dearborn Partners. Shaw Development is a leading designer, manufacturer and assembler of sensors, fluid management systems and related components primarily for diesel exhaust fluid (DEF) applications. Monomoy’s investment in Shaw will be reflected as one of the firm’s most successful partnerships.

Monomoy played an integral role in helping to grow the family-owned business into a market leader in the DEF sector by focusing on operational improvements. In addition to playing a key role in expanding Shaw’s leadership team, Monomoy’s ownership enabled Shaw to expedite the integration of data and tech-based solutions, identification and execution of an aftermarket strategy and expansion of Shaw’s international footprint. The successful growth of Shaw reflects Monomoy’s nineteen years of experience investing in family-run, middle-market industrial businesses and partnering with companies to implement an operations-driven value-creation strategy.

“Monomoy’s collaborative approach, operational expertise and strategic understanding of our business led to an incredible partnership that has set us up for continued opportunities for innovation and excellence in the years to come,” said Shaw CEO Keith Luomala. “Our united commitment to improve the business created lasting value for Shaw and our future partners. We are undoubtedly well-positioned for further growth as we embark on this next chapter.”

Founded in 1944, Shaw provides superior customer value with innovative solutions and custom-engineered products for a sustainable future. Shaw meets rigorous environmental standards with its advanced sensor technology, filtering products and fluid management solutions for diesel and alternative fuel components. Shaw’s sensors and systems are mission-critical components of emission and fluid control systems and are provided to OEMS in a variety of industrial and transportation end markets.

“Monomoy is immensely proud of our partnership with Shaw, and we are honored to usher the team into this next phase of long-term growth under Madison Dearborn’s ownership,” shared Monomoy Investment Team Managing Director Mel Bartoul. “This sale is a testament to our in-house operating team, dedicated to rolling up their sleeves and working alongside family-owned businesses like Shaw. We look forward to partnering with future businesses as we aim to accelerate their growth and position them for long-term success.”

Jefferies LLC served as exclusive financial advisor to Shaw Development and Monomoy with respect to the transaction; TD Cowen advised the Board of Directors of Shaw Development.
