ABC Supply Holding Corp., Beloit, WI, the parent company of American Builders & Contractors Supply Co., Inc. (ABC Supply), has entered into a definitive agreement to redeem all of the shares held by its minority shareholders, an investor group led by Advent International. Upon the closing of the transaction, 100 percent of the shares of ABC Supply will be controlled by the company’s co-founder Diane M. Hendricks.

In 2010, Advent sponsored ABC Supply’s acquisition of its portfolio company, Bradco Supply, and became a large minority shareholder. Advent and other minority holders are now exiting the investment.

“We are pleased that our operating performance has allowed both majority and minority shareholders to accelerate their plans for the share redemption,” David Luck, chief executive officer and president of ABC Supply, said.

The transaction is expected to close in April 2013.
