Slate Capital Group

Slate Capital Group

Erik Ginsberg, Rick Corcoran, and Parker Davis run Slate Capital Group, a Baltimore-based buyout shop founded in 2004. Three partners — not a 40-person platform — make every investment decision and commit personal capital alongside the external capital they raise from high-net-worth individuals and single-family offices. The firm targets control positions in companies generating $3 million to $30 million in annual EBITDA, operating in business services, distribution, and select light manufacturing. Current portfolio companies demonstrate the narrow focus: B&S Site Development serves data-center construction in Northern Virginia; Cumberland Diversified Metals distributes specialty alloys; and Vertical Mechanical Group contracts HVAC and plumbing for large hotel and multifamily projects in the Mid-Atlantic. Slate structures deals as growth capital, acquisition financing, management buyouts, or recapitalizations, and limits geographic exposure to the eastern United States. Slate has never disclosed assets under management, but its cadence is explicit: one or two new platforms per year, with eight named current and past holdings across five portfolio pages and a since-merged HVAC platform formed from a 2021 combination. The firm operates out of Baltimore, Cincinnati, and Nashville. In 2021, it backed the merger of Anderson Mechanical Services and Inspiration Plumbing Company to create Vertical Mechanical Group, which now services Clark Construction, Hitt Contracting, and Whiting-Turner. The structural differentiator is permanent-hold economics. Slate’s principals invest alongside family-office LPs without a fixed fund life, meaning they can own Cumberland Diversified Metals for decades and compound value through operations rather than exit timing. That patient-liability structure makes Slate resemble a holding company more than a conventional 5-to-7-year private equity fund.
