Cornerstone Building Brands, Inc. (the “Company”), the largest manufacturer of exterior building products in North America, completed the previously announced sale of its Roll-up Sheet Door business to Janus International Group, Inc. (“Janus”) in a cash transaction for $168 million, subject to customary adjustments. The transaction includes products sold under the DBCI brand.

The completion of the divestiture sharpens Cornerstone Building Brands’ portfolio and positions the Company for further growth in large, deep markets, which we believe will fuel additional value creation.
