Helmkamp has been appointed Non-Executive Chair of its Board of Directors, effective October 1, 2022. Ms. Helmkamp has served as an independent director and member of the IDEX Board since November 2015, and as a member of multiple Board committees, including as Chair of the Nominating and Corporate Governance Committee.

Cook, who after fourteen years of serving on the IDEX Board has announced his intention to retire. Mr. Cook has been an invaluable contributor to the Board of Directors and the company, serving in various leadership roles including as a member and Chair of the Audit Committee, Lead Director, and most recently, as Non-Executive Chairman of the Board. Ms. Helmkamp continued, “It is no surprise that the National Association of Corporate Directors (NACD) named Bill Cook its ‘Public Company Director of the Year’ in 2021. His presence will be greatly missed by the Board, and I am honored to continue the work to support IDEX in creating value for shareholders and innovative and valued solutions for customers.” Mr. Cook noted, “What first attracted me to the IDEX Board of Directors remains there today. It is a world-class Board, bringing together highly intelligent and results-driven business executives in a very collaborative culture, where everyone always brings their ‘best game.’ Katrina is a natural choice to be the next Chair of the Board of Directors. She has what it takes to be an outstanding leader.”

“As we look to the future, I am excited to continue working with Katrina to build on IDEX’s long track record of success,” said Eric D. Ashleman, CEO and President of IDEX Corporation. “I also want to thank Bill, on behalf of the entire organization, for the remarkable leadership and unwavering encouragement he has provided during his 14 years of service on the IDEX Board.” With Mr. Cook’s departure, effective October 1, 2022, the size of the Board will decrease from 11 to 10 directors.
