Commercial exterior building products manufacturer NCI Building Systems today announced the completion of its merger with residential exterior building products manufacturer Ply Gem Parent.

NCI shareholders retained 53% ownership of the company's common equity with Ply Gem shareholders now owning 47%. Under the terms of the agreement, Ply Gem shareholders received approximately 58.7 million shares of NCI common stock.

The companies signed an agreement for combination in a stock-for-stock merger on July 17. The combined company will operate under a name yet to be determined, with each entity preserving its existing established brands. The company will be headquartered in Cary, N.C., with a significant presence in Houston, Texas, according to the press release.

"We are delighted to successfully complete our merger with Ply Gem today, furthering our strategy to be a market leading building products company, " chairman and CEO of NCI James S. Metcalf said. "This combination brings together industry leaders that will increase our scale, broaden our product offerings, and expand our customer base."

Ply Gem was acquired by private equity firm Clayton Dublier & Rice in January and combined the manufacturer with Atrium Windows & Doors.
