Tonka Bay Equity Partners Sells a Majority Stake in All Flex

Minnetonka, Minn. (January 11, 2011) – Tonka Bay Equity Partners (“Tonka Bay”) today announced the completion of a successful sale of a majority stake of its portfolio company, All Flex, a specialty manufacturer of flexible circuits based in Northfield, MN.

Tonka Bay led a management buyout in early 2007 to create liquidity for the founder.  Following four years of strong growth, in December 2010, Tonka Bay’s minority co-investor, Granite Equity Partners, acquired All Flex.  As part of the transaction, Tonka Bay retained securities and will remain on the board of directors.

“Tonka Bay has been a great partner. Their practical support and collaborative style helped us develop our strategy and build our team.  We look forward to their board involvement in the future,” said Greg Closser, CEO of All Flex.

The Company grew solidly over the past four years and added a CFO, as well as a new VP of Sales and Marketing during that time.  In addition, All Flex dramatically increased service levels and on-time delivery, while streamlining operations through the implementation of LEAN manufacturing techniques.

“After four years of working alongside management and the board to help realize the strategic plan, we are thrilled with the result of the sale.  The management team has done a terrific job and we believe the Company has a bright future,” said Peter Kooman, Managing Principal of Tonka Bay.
