Platinum Equity, a global investment firm, completed the acquisition of a majority stake in The Cook & Boardman Group, a specialty distributor of commercial door and security integration solutions, from Littlejohn, an investment firm. Financial terms were not disclosed. "Cook & Boardman has built an impressive, diversified business with national scale. Customers in this space want more than just a traditional distributor of doors and hardware. They increasingly need value added solutions, including electronic safety and security systems. We believe Cook & Boardman is uniquely positioned to capitalize on that growing demand for integrated solutions. We look forward to working with the company's leadership group and our partners at Littlejohn to continue growing the business," Jacob Kotzubei, Platinum Equity Co-President.
