Global Distributor of Specialty Building Materials will Serve as Clearlake’s Latest Platform for Organic Growth and Add-on Acquisitions in the Specialty Distribution Sector


LOS ANGELES, CA, SANTA MONICA, CA AND IRVING, TX (November 16, 2020) – Platinum Equity announced today the signing of a definitive agreement to sell PriSo Holding Corporation (“PrimeSource”, or the “Company”) to Clearlake Capital Group, L.P.

The Company plays a crucial role for its customers who rely on its superior brand value, breadth of offering and sourcing and logistics capabilities.


Platinum Equity acquired PrimeSource in 2015 from Itochu Corporation. Following the acquisition, Platinum Equity’s M&A and operations teams drove a comprehensive operational improvement and transformation program.


“We deployed the full range of our M&A&O toolkit, helping the company grow strategically while enhancing its capabilities in supply chain management, logistics, salesforce effectiveness and technology applications,” said Platinum Equity Partner Jacob Kotzubei. “By investing in growth and fundamentally improving the Company’s operational underpinnings, PrimeSource substantially increased earnings and is well positioned to sustain its momentum.”


“PrimeSource has been a fantastic success story,” said Platinum Equity Managing Director Todd Golditch. “Platinum Equity has a demonstrated track record successfully investing in and creating value in the building products space over many years and PrimeSource is no exception.  It has been a pleasure partnering with the PrimeSource management team led by Tom Koos, and we look forward to following the company’s continued success in the years ahead.”


PrimeSource CEO Tom Koos said he is proud of the collaboration with Platinum Equity and excited about the opportunity to partner with Clearlake.


“We are grateful to Platinum Equity for the support over the past several years.  They have been instrumental in transforming PrimeSource and their operating model has been key to our success,” said Mr. Koos. “Our leadership group is thrilled for the next step. I have known José  E. Feliciano, Behdad Eghbali, Colin Leonard and the team at Clearlake for over a decade, having not only been a CEO for one of their previous portfolio companies but also in my capacity as a board member and advisor to several Clearlake portfolio companies. They are the optimal partners for PrimeSource at this stage in our Company’s evolution.  We are looking forward to continuing our exciting growth trajectory in the coming years.”


“We are excited to partner with Tom, Bill, and the entire PrimeSource management team,” said José E. Feliciano, Co-Founder and Managing Partner at Clearlake. “This new investment is a great example of our focus and expertise in the specialty industrial distribution sector. We look forward to leveraging Clearlake’s O.P.S.® playbook to capitalize on the Company’s market leadership and strong momentum to accelerate growth through both organic initiatives and acquisitions.”


“We have long admired PrimeSource for the breadth of its distribution network and unparalleled sourcing infrastructure. We look forward to investing behind the Company to bolster these capabilities, expand our product offering and increase the value PrimeSource delivers to its customers,” said Colin Leonard, Partner at Clearlake.
