Owens Corning Names Todd Fister Chief Financial and Operating Officer to Accelerate Organic Growth and Strengthen Market-Leading Positions

TOLEDO, Ohio--(BUSINESS WIRE)--Owens Corning (NYSE: OC), a branded building products leader, today announced that Todd Fister has been promoted to Executive Vice President and Chief Financial and Operating Officer, effective today. This expanded role reflects Owens Corning’s continued focus on operational discipline and integrated execution to accelerate organic growth, enhance margins, and strengthen market‑leading positions, in line with the company’s most recent Investor Day.

In this role, Fister will assume responsibility for executing key enterprise initiatives that drive growth and performance. By leveraging The OC Advantages™ – including Owens Corning’s iconic brand, unparalleled commercial strength, leading technology, and winning cost position – he will enhance the execution of the company’s integrated go-to-market strategy while simplifying and standardizing work across the enterprise. These efforts support the company’s ability to structurally lower costs, improve capital efficiency, and redeploy savings to fund organic growth and disciplined capital allocation.

Fister has served as Owens Corning’s Executive Vice President and Chief Financial Officer since 2023, and will operate in a combined role providing both operational and financial leadership as the company conducts an external search for a Chief Financial Officer.

“Over the past few years, we have reshaped Owens Corning into a focused, branded building products leader in North America and Europe. With the sale of our glass reinforcements business, we are now positioned to operate as a more integrated company and capture the full value of our complementary product platforms,” said Brian Chambers, Chair and Chief Executive Officer. “With over 11 years of service at Owens Corning, Todd is a proven and respected leader. His deep strategic and operational expertise, combined with his knowledge of our people and the building products industry, will be critical as we capture the benefits of a more focused company by unlocking efficiencies, strengthening execution, and accelerating our organic growth to create more value for customers and shareholders.”

Fister served as President of the company’s Insulation business from 2019 to 2023 where he led the transformation of the business to deliver growth and stronger margins. More recently, he was a key architect of the enterprise strategy that positions Owens Corning for organic growth and market‑leading margins. Fister joined Owens Corning in 2014 after holding leadership roles across finance, corporate development, and strategy at MeadWestvaco, now part of Smurfit Westrock, as well as Kimberly‑Clark and Procter & Gamble.
