Stone River Capital Partners

What Stone River Capital Partners does

Stone River Capital Partners, LLC ("SRCP") is a small private equity investment firm headquartered in Birmingham, Michigan, that targets profitable middle-market companies with revenues between $10 million and $100 million. The firm pursues buyouts, recapitalizations, and growth equity investments, and positions itself as a hands-on partner to management teams, emphasizing customized transaction structures rather than standardized deal templates. Its website highlights deep operating experience in management, finance, and operations as its primary value-add.

SRCP's portfolio is concentrated in the specialty industrial and defense-adjacent manufacturing sector. The three disclosed holdings are Fabco Automotive Corporation (specialty gearboxes, axles, and transfer cases for severe-service commercial vehicles, in business since 1918), Burtek Enterprises, Inc. (customized military mobile ground systems including radar platforms, vehicles, shelters, and trailers), and R. Cushman and Associates (power transmission products for military vehicles, airport rescue equipment, heavy-duty trucks, drilling rigs, and steel/mining drives). Fabco was acquired from Accuride in September 2011, Burtek was acquired in partnership with Wynnchurch Capital in February 2012, and R. Cushman was added as a Fabco add-on in April 2012.

The firm's go-to-market is relationship-driven and offline: sourcing is conducted through industry networks and direct outreach to business owners, with no public marketing or deal pipeline disclosed. There is no evidence of a fund vehicle, limited partner base, or AUM being publicly disclosed. SRCP relies heavily on a co-investment relationship with Wynnchurch Capital to scale its deal capacity, and there is no visible activity, press release, or portfolio update on the firm's website beyond April 2012, suggesting a low and possibly dormant investment cadence.

Direct peers

• Wynnchurch Capital: Mid-market private equity firm focused on corporate carve-outs, recapitalizations, and special situations in industrial and manufacturing businesses. Most directly comparable given its documented co-investment partnership with SRCP on Burtek and R. Cushman, with similar deal size and end-market orientation.
• Pritzker Private Capital: Middle-market private equity firm investing in North American industrial businesses, often via corporate divestitures and family-owned transitions. Comparable to SRCP in industrial focus, customized deal structuring, and $10M-$100M revenue target band.
• Huron Capital Partners: Detroit-area middle-market private equity firm investing in lower-middle-market companies, often partnering with management. Highly comparable given shared Midwest industrial base and operating-partner orientation.
• Incline Equity Partners: Lower-middle-market private equity firm focused on distribution, industrial, and business services companies. Comparable target-company size, sector overlap, and operating-partner value-creation approach to SRCP.
• Shore Capital Partners: Chicago-based lower-middle-market private equity firm focused on buyouts of businesses generating $10M-$100M+ in revenue. Directly comparable niche focus and company size profile to SRCP.
• Sterling Group: Houston-based middle-market industrial private equity firm focused on manufacturing, distribution, and industrial-services businesses. Similar industrial-sector concentration and middle-market buyout orientation.
• Sentinel Capital Partners: Lower-middle-market private equity firm investing in management buyouts and recapitalizations of $10M-$100M+ revenue businesses. Comparable size band and transaction approach.

Broad incumbents

• KKR & Co. Global private equity giant with broad industry exposure including industrial buyouts. Overlaps with SRCP in industrial-business investing but operates at much larger scale across broader geographies and strategies.
• The Carlyle Group: Global private equity firm with dedicated industrial and aerospace/defense franchises. Overlaps with SRCP's defense (Burtek) and industrial drivetrain portfolio themes but at vastly larger fund sizes.
• Apollo Global Management: Large global alternative asset manager with industrial and business-services buyout exposure. Represents the broader incumbent PE universe SRCP competes within for industrial deal flow.
