Concurrently, and as part of a long-standing succession plan, the Board announced Don Tarry as the company's next President and CEO.

Pat joined TXNM Energy in June 2007 as Utilities President, overseeing operations for wholly owned subsidiaries PNM in New Mexico and TNMP in Texas.

To align with New Mexico's goals for a clean energy future, TXNM Energy became the first investor-owned utility to announce a goal of 100% carbon-free generation by 2040 and has demonstrated significant progress on this goal, reaching 72% carbon-free generation capacity in 2024.

Pat remains committed to serving her community as the Chair of the New Mexico Partnership under Governor Michelle Lujan Grisham, Trustee of the University of New Mexico Foundation and as a board member of the Kirtland Partnership Committee.

"Pat's remarkable leadership has advanced our utilities, our teams, our communities and the industry as we navigated a changing energy environment," said Norm Becker, lead independent director of TXNM Energy. "The board of directors extends our heartfelt appreciation for Pat's steady and thoughtful approach, and we value her continued board guidance. We are confident in Don's ability to continue moving our utilities forward as we pursue cost-effective solutions to serve our customers' growing needs."

Don Tarry, current President and Chief Operating Officer of TXNM Energy, joined the company in 1996 and previously served in various leadership roles including Senior Vice President and Chief Financial Officer, Vice President of Customer Service, Chief Information Officer, Controller and Treasurer.

"Don's breadth of knowledge combined with his commitment to our customers and communities is unmatched," said Pat Collawn. "I have seen first-hand the growth and success his teams have accomplished for the benefit of our customers and know that he will continue this strong track record as he leads TXNM Energy into the future."

Don is actively involved in his community, serving as the current Chair of the Albuquerque Regional Economic Alliance and as a member of the Board of Directors for the Greater Albuquerque Chamber of Commerce.
