Williams (NYSE: WMB) today announced that effective July 1, 2025, President and CEO Alan Armstrong will become executive chairman of the Williams Board of Directors and Chad Zamarin, currently executive vice president of Corporate Strategic Development, will succeed him as president and CEO and will join the Williams board. Stephen Bergstrom, current chairman of the board, will transition to lead independent director.

Bergstrom expressed the board's support for this transition, stating, "Alan’s remarkable leadership and commitment to the mission, vision and values of Williams has been fundamental to the company’s success. On behalf of the board of directors and the entire company, we extend our heartfelt appreciation to Alan for his exceptional leadership as president and CEO for the past 14 years and for his dedication to Williams during his nearly four decades of service. This transition is the result of a thoughtfully planned, multi-year succession process, and the board and I are confident that Chad will continue to guide Williams to success in the evolving energy landscape."

Armstrong began with Williams as an engineer nearly 40 years ago and has served the company with extraordinary dedication. Under his leadership, Williams achieved significant milestones, including remarkable growth and success. Notably, Armstrong honed the company’s natural gas focused strategy, with an emphasis on expanding Williams' natural gas transmission, storage, gathering and processing infrastructure. Armstrong has been a strong advocate and leading voice for the natural gas industry, currently serving as chair of the National Petroleum Council and as a founding member of Natural Allies for a Clean Energy Future.

"As I look at where the company is today, Williams is excelling on all fronts thanks to a strong and energized organization that is very passionate and dedicated to our strategy and to doing the right thing. I have seen first-hand what this company can accomplish and overcome, and I am confident our best chapters are still ahead as demand for natural gas continues to accelerate and the value of our critical energy infrastructure is realized,” said Armstrong. “Since joining Williams, Chad and I have worked together closely, and he has successfully built on our strong natural gas focused strategy, while advocating for Williams and for the role of natural gas in our clean energy future. He is the right next leader for Williams at this point in our company’s history, and I know he will take the company forward with pride and commitment to our values.”

Zamarin's experience in the energy industry, coupled with his deep understanding of and commitment to Williams’ strategic direction, complement his appointment to this new role. Since joining Williams in 2017, he has led the company’s expansion by guiding the corporate strategy process, delivering strategic acquisitions and providing commercial leadership across the company’s various businesses, geographies and customers. Under his leadership, the New Energy Ventures team has led the industry with innovative energy solutions, and its Power Innovation group is delivering speed-to-market solutions for growing data center demand.

“I am humbled to take on this new role as Williams’ president and CEO,” said Zamarin. “The story of Williams is that of one of the greatest American companies. Our company’s more than one-hundred-year track record of tackling some of the most complex infrastructure challenges is inspiring, and I look forward to building on that foundation. Alan has been an amazing mentor, leader and thought partner, and I’m grateful for the trust that he and the Williams Board of Directors have placed in me to carry Williams’ vision forward.”
