USG Corporation, a building materials manufacturer, has announced that its president/CEO, Christopher Griffin, will retire later this year after more than 30 years of service. Concurrent with this news, USG’s board of directors and owner Knauf Group have appointed Christopher Macey—currently USG’s COO—as president and CEO, effective April 1, 2026.

Celebrating a Legacy of Leadership as USG Approaches its 125th Year

Griffin’s retirement marks the conclusion of a distinguished career spanning more than 35 years in the building materials industry, including over 30 years with USG Corporation and its subsidiaries. He was appointed CEO in 2019.

“It has been the honor of my professional life to lead USG and work alongside the most talented team in the industry,” said Griffin. “Since I joined nearly three decades ago, we have lived up to our reputation for innovation while investing in our people, modernizing our facilities, and being the best and easiest building materials manufacturer to do business with for our customers. As we approach USG’s 125^th anniversary, I am proud of what we have accomplished together and am confident the company is well positioned for its next chapter of growth over the next century.”

Under Griffin’s leadership, USG successfully navigated its transition to a privately held company under Knauf ownership, while significantly expanding its positions in wallboard and ceilings. “His tenure has been defined by a ‘customer-first’ philosophy and a commitment to safety and employee engagement that has consistently surpassed industry benchmarks,” a media release said.

“On behalf of the Knauf family and USG’s board of directors, I want to sincerely thank Mr. Griffin for his visionary leadership and unwavering commitment to our people, our customers and our performance. He leaves the company well positioned for the future,” said Dr. Uwe Knotzer, general partner of Knauf Group. “We warmly welcome Christopher Macey as USG’s next President and CEO and look forward to working with him to build on our momentum and continue delivering for customers and communities across North America.”

A Leader for the Next Chapter

Mr. Macey brings more than 30 years of experience in the building materials industry and a strong record of operational leadership and commercial execution. As COO of USG, he led the company’s manufacturing, supply chain and digital transformation initiatives. Previously, Macey served in several senior leadership roles, leading CGC (Canada) and USG Mexico/LATAM, and more recently, as including president of USG’s Gypsum Division.

In his new role as President and CEO, Macey will be responsible for driving USG’s strategic priorities, including continued investment in manufacturing, customer service excellence and talent development across the business.

Macey said,”USG’s rich history and reputation for excellence are well known in our sector. I am grateful for the strong foundation Chris Griffin and the USG team have established, and I look forward to working together as we continue to serve our customers and innovate for the future.”
