Cornerstone Industrial Group

What Cornerstone Industrial Group does

Cornerstone Industrial Group, LLC is a privately held investment firm headquartered in Chagrin Falls, Ohio, founded by Michael C. Adams in 1997 (actively acquiring since 1998). The firm acquires and holds niche manufacturers, distributors, and service providers for long-term ownership, explicitly positioning itself as an alternative to traditional private equity by avoiding fund-cycle exit pressure and partnering with incumbent management. Target businesses have EBITDA greater than $1 million, branded or proprietary products, sustainable competitive advantages, and a preference for no prior institutional ownership; geographic focus covers the Eastern half of the United States, with the Great Lakes Region and Northeast as primary markets and Southeast added via a 2021 acquisition.

Cornerstone has completed nine acquisitions across sectors including industrial technology, niche manufacturing, medical technology, precision and engineered components, test and measurement, value-added distribution, and B2B e-Commerce. The current active portfolio comprises two wholly owned operating companies: Terrawise Solutions (a Leica Geosystems construction-technology dealer in the Southeastern US, acquired 2021) and Sharpe Engineering & Equipment (a food processing and packaging engineering firm in Wisconsin, acquired 2023). Seven prior holdings have been realized through sales to strategic buyers, family offices, private equity buyers, and management buyouts, including Swiss-Tech, LLC (realized 2018), Wahl Refractory Solutions (realized 2020), and Gasko Fabricated Products (realized 2012).

The firm is operationally tiny (1-10 employees at the parent level), generates revenue through ownership economics and exits rather than fees or product sales, and reaches acquisition targets through a direct, sales-led approach anchored by its website, professional networks, and referrals. Leadership consists of two named principals: Founder and Managing Director Michael C. Adams (former investment banker with experience at NatCity Investments, Reserve Capital Group, Prescott, Ball & Turben, and L.F. Rothschild; 50+ transactions) and Director Christopher J. McKenna (joined as Partner in 2021; founder of Carleton McKenna & Co. and former CEO of Furnace Parts, LLC). The firm operates as Cornerstone Industrial Group, LLC in Ohio, doing business as CIG, LLC, with DBA previously known as Cornerstone Industrial Holdings.
