I also want to thank Mary for her leadership and guidance over the years and know I will benefit from her continued support as Chairman.”

Before joining Johns Manville, Wamboldt worked 16 years at PPG Industries Inc., where he held a variety of positions in the company’s Fiber Glass and Coatings divisions. He earned a bachelor’s degree in chemistry from Lehigh University. He and his wife live in Denver.

Rhinehart became Johns Manville’s President and CEO in 2012 and assumed the additional role of Chairman in 2014.

During her more than 40 years with Johns Manville, she also held leadership roles in treasury, supply chain, M&A and human resources, and she managed several of the company’s business units.

“I am immensely proud of JM’s employees and all we have accomplished together,” Rhinehart said. “Johns Manville is an important part of my life, and its continued success is my top priority as we transition to new leadership. I am pleased to hand the company over to such an accomplished JM executive as Bob and am confident he and our 8,000 employees around the world will continue to build on JM’s 162-year track record of success.”

Johns Manville became a Berkshire Hathaway company in February 2001.

“Bob’s business acumen, broad base of experience, and extensive industry knowledge make him the natural successor to Mary as CEO,” said Greg Abel, Berkshire Hathaway’s Vice Chairman. “I also want to extend my gratitude to Mary for her dedication and commitment to JM over her entire career. Under her leadership as CEO, JM delivered exceptional performance, successfully expanded its market presence, and made sound, strategic investments to position the company for success well into the future.”

Warren Buffett, Chairman and CEO of Berkshire Hathaway, added: “Mary was everything we had hoped to find in a CEO.”
