Investor Group Led by Swiftsure Capital Acquires Quantum Windows and Doors

Oct 14, 2015

Investor Group Led by Swiftsure Capital Acquires Quantum Windows and Doors October 14, 2015 07:00 AM Eastern Daylight Time SEATTLE & EVERETT, Wash.--( BUSINESS WIRE )--A private equity acquisition group led by Swiftsure Capital today announced that it has acquired Quantum Windows and Doors, an Everett-based manufacturer of custom architectural wood windows and doors. The acquisition will not affect Quantum’s day-to-day operations. As part of the acquisition, Jeff Klein has been appointed Chief Executive Officer of Quantum. Klein, a leading senior executive in the window manufacturing industry, was previously Senior Vice President of Ply Gem Industries, Inc. and President of several window companies owned by Ply Gem. Prior to working with Ply Gem, Klein was Senior Vice President of Milgard Manufacturing which was sold in 2001 to Masco Corporation. Investors affiliated with Swiftsure Capital were joined by Nitze-Stagen Capital Partners to fund the acquisition. Peter Nitze, President of Nitze-Stagen Capital Partners, will become a member of the Quantum board of directors. Gordon Gardiner, Managing Partner of Swiftsure Capital, Bill Lewis, Chairman of Lease Crutcher Lewis, and Bill Douglass of Swiftsure will also join the Quantum board, together with Mr. Klein. “Quantum is a national leader in custom wood window manufacturing,” Klein said. “They have set the standard for superb craftsmanship and are the go-to name for complex architectural projects that very few companies can execute. I look forward to building on the extraordinarily strong reputation that Quantum has in the industry.” Quantum was founded in 1982 as a response to the industry's demand for a better built custom wood window. Quantum's founders were general contractors dissatisfied with the mass produced windows available, so they introduced a window that reflected the same craftsmanship that went into the homes they built. Response to the product was excellent and Quantum's reputation grew quickly. Over the years Quantum product lines have expanded and market reach has become international. “There are a number of well-managed Northwest companies, like Quantum, that are seeking a change of ownership for generational transition issues or otherwise,” Gardiner said. “Swiftsure’s goal is to find those companies and help them realize their full growth potential. We’re happy to have led this deal for Quantum, and we look forward to seeing the company flourish.” About Quantum Windows and Doors Quantum Windows is an industry-leading manufacturer of hand-crafted wood windows and doors.
