Milwaukee, Wis. – A. O. Smith Corporation (NYSE: AOS), a global leader in water technology, announced today that Executive Chairman Kevin Wheeler will retire effective July 1. The company’s board of directors has elected Stephen Shafer, president and chief executive officer (CEO), as chairman upon Wheeler’s retirement.

“Kevin’s impact on A. O.

Wheeler joined A. O. Smith in 1994 as a regional sales manager for the former Water Products Company and held various senior leadership roles across the business before becoming president and CEO in 2018 and chairman in 2020.

Shafer, who has served as president and CEO since July 2025, becomes the 11th CEO to assume the role of chairman in the company’s history. He joined A. O. Smith in 2024 as president and chief operating officer. As chairman, Shafer will lead the board of directors and continue to oversee the company’s global operations, strategic direction, profitability and shareholder return.

“Steve has demonstrated strong, strategic leadership and a deep understanding of our business and growth opportunities,” said Mapes. “His combined role as chairman and CEO will further strengthen alignment across our strategy, operations and long-term value creation.”

Before joining A. O. Smith, Shafer held roles of increasing responsibility at 3M Company across multiple business units in the U.S. and China.

“As chairman, I will continue leading this outstanding company and team with focus and discipline,” said Shafer. “We remain committed to driving innovation, serving our customers and advancing our purpose to find a better way. I would also like to thank Kevin for his leadership and continued support through this transition and look forward to benefiting from his continued guidance as a member of our board going forward.”
