USG Corp. said President and CEO Christopher Griffin will retire later this year, ending a career of more than 30 years with the building materials manufacturer. The company’s board and owner Knauf Group have appointed Chief Operating Officer Christopher Macey as president and CEO, effective April 1.

Griffin has served as CEO since 2019, following USG’s acquisition by Knauf. During his tenure, the company expanded its wallboard and ceilings businesses and completed its transition to private ownership.

“It has been the honor of my professional life to lead USG,” Griffin said, adding that the company is “well positioned for its next chapter” as it approaches its 125th anniversary.

Knauf Group General Partner Dr. Uwe Knotzer said Griffin leaves the company “well positioned for the future.”

“I am grateful for the strong foundation Chris Griffin and the USG team have established,” Macey said. “I look forward to working together as we continue to serve our customers and innovate for the future.”
