Tenex Capital Management Portfolio Companies US GreenFiber and SouthernCarlson Close Acquisitions of Central Fiber Insulation and Duo-Fast Carolinas

New York, New York – November 13, 2015 – Tenex is pleased to announce the completion of two recent add-on acquisitions via two existing portfolio companies. On September 25th, US GreenFiber closed the acquisition of Central Fiber Insulation, a carveout of the environmentally-friendly cellulose insulation division of Central Fiber LLC; and on October 29th, SouthernCarlson closed the acquisition of Duo-Fast Carolinas, a North Carolina-based and family owned distributor of power-driven fasteners and pneumatic power tools used in the residential construction and general industrial manufacturing end-markets.

The acquisition of Central Fiber represents the fifth add-on acquisition US GreenFiber has completed during Tenex’s less than two years of ownership. As the largest domestic market participant, and the only company with national sales and distribution, US GreenFiber believes the acquisition of Central Fiber will further establish the company’s scale and market presence.

The acquisition of Duo-Fast Carolinas represents the fourth company Tenex has aggregated into what is now SouthernCarlson, a company Tenex formed in November 2014 through the merger of Carlson Systems and Southern Fastening Systems, two similarly sized national distributors of power-driven fasteners, specialty tools, and packaging supplies. The combined company’s new brand was announced last week at the 39th annual Specialty Tools & Fasteners Distributors Association (“STAFDA”) show.
