MINNEAPOLIS (January 29, 2026) — Donaldson Company, Inc. (NYSE: DCI) (Donaldson or the Company), a global leader in technology-led filtration products and solutions, announced that the Company's board of directors has elected chief operating officer Richard Lewis as president and chief executive officer, effective March 2, 2026.

"On behalf of the Board, we extend our sincere appreciation to Tod for his exceptional leadership and decades of service," said Christopher Hilger, Lead Independent Director.

With Rich's deep understanding of Donaldson's businesses and operations, the Board is confident the Company will continue to execute well and build on its long track record of success."

Carpenter said, "Elevating Rich to the president and CEO role reflects our long-term succession planning process and comes at a time when Donaldson is in a strong position thanks to the talent, dedication, and discipline of our global team. Throughout his time with the Company, Rich has played an integral role in shaping and executing our strategy, and I am confident in his ability to lead Donaldson into its next phase of growth and value creation."

Lewis said, "I am excited about the opportunities in front of us. We have a strong leadership team, a clear strategy, and a culture deeply committed to our customers and operational excellence. I look forward to building on the momentum established under Tod's leadership and continuing to deliver value for our employees, customers and shareholders."
