Summary
New Mountain Capital completed the acquisition of Seattle-based Cumming Group from Tailwind Capital in December 2021, establishing a partnership in which Tailwind retained an equity stake alongside New Mountain. While transaction terms remained undisclosed, the deal represented a significant refinancing and ownership transition for the international project and cost management consultancy.

Cumming Group maintains substantial operational scale with 1,100+ employees distributed across 41 offices globally. The firm serves blue-chip clients across diversified end markets including education, healthcare, technology, commercial, infrastructure, and other sectors worldwide. Since its founding in 1996, Cumming has completed project work valued in excess of $300 billion, positioning itself as a strategic advisor for complex, high-profile initiatives requiring specialized expertise in cost and schedule management.

The transaction followed a period of significant value creation under Tailwind Capital's sponsorship. Revenue expanded substantially during Tailwind's ownership, with earlier historical data showing growth from $25 million in 2006 (when Long Point Capital held the investment) to over $100 million by 2021. During Tailwind's tenure, Cumming executed eight add-on acquisitions—including TowerEight in London (2020) and Inici Group in Portland (2021)—while establishing regional operations in the Middle East and expanding into new service sectors.

New Mountain Capital's partnership with Cumming reflects a growth-oriented strategy designed to leverage the firm's scale and market position. Management commentary indicated the partnership would enable Cumming to pursue additional organic growth initiatives and acquisition targets while maintaining operational continuity. Jefferies and Lincoln International served as financial advisors to the transaction, with Davis Polk & Wardwell providing legal counsel to support the recapitalization structure.
