The Berkshire Hathaway-owned manufacturer has announced that John Vasuta will become the company’s new President and Chief Executive Officer beginning August 1, 2026. He will succeed Bob Wamboldt, who is retiring after more than two decades with the company.
The announcement came directly from Johns Manville through its official company release. The transition marks one of the most important leadership moves for the building and industrial materials manufacturer in recent years.
John Vasuta to Lead the Company
