Private equity firm Clearlake Capital Group completed the acquisition of PrimeSource, a global distributor of specialty building materials, from Platinum Equity. Financial terms were not disclosed. "PrimeSource showcased the breadth of our M&A&O toolkit and the ways Platinum creates value throughout the entire lifecycle of an investment. We started by providing a divestiture solution to a large corporate seller, then executed a comprehensive transition and transformation program that established PrimeSource as a solid platform for growth as an independent company. The business thrived under our stewardship, to the benefit of its customers, suppliers, employees and their communities," Jacob Kotzubei, Platinum Equity Partner.
