McCormick is widely recognized within the company and the broader energy sector for his exceptional contributions over a 20-year span, having played a crucial role in the company's legal affairs and strategic positioning.

McCormick has been essential to the development of ONE Gas, providing guidance during a pivotal time in its history. Before the establishment of ONE Gas as an independent entity separate from ONEOK Inc., he served as the associate general counsel for ONEOK. His involvement has shaped the company's legal framework significantly, establishing robust compliance protocols and governance structures that continue to support its operations.

The announcement was made on July 1, 2025, by CEO Robert S. McAnnally, who acknowledged McCormick's influence and leadership. In a statement, McAnnally expressed gratitude for McCormick's unwavering commitment and sound judgment, stating, “Joe has been a cultural force for our organization and an inclusive leader who has reinforced our Core Values and high ethical standards.” McAnnally also extended well wishes for McCormick’s next chapter in life, recognizing the invaluable legacy he leaves behind.

In preparation for this transition, Regina L. Gregory has been appointed to succeed McCormick as senior vice president, general counsel, and assistant corporate secretary. Gregory will officially assume her duties on October 1 but will join the executive leadership team as a senior advisor to McAnnally on July 16. This period will allow her to collaborate closely with McCormick, ensuring a seamless transition of responsibilities.

Gregory comes to ONE Gas with a wealth of experience in the energy sector, having served as the executive vice president, general counsel, and corporate secretary at Targa Resources Corp.. Her extensive background includes senior leadership roles at other energy companies and legal practice at notable firms such as Jones Day and Norton Rose Fulbright. Over her career, she has successfully led legal departments, oversaw major transactions, and managed complex litigation. Gregory’s legal acumen is backed by her academic credentials, holding a Juris Doctor (JD) from the University of Oklahoma, where she graduated with the highest honors.

Upon her appointment, Gregory expressed her eagerness to lead and contribute strategically to ONE Gas, indicating she is ready to uphold the high standards of excellence that McCormick exemplified. The leadership at ONE Gas anticipates her addition will further enhance the company’s legal standing and governance.

ONE Gas operates as a fully regulated natural gas utility, serving over 2.3 million customers across Kansas, Oklahoma, and Texas. As a component of the SP MidCap 400 Index, the company plays a crucial role in delivering affordable energy solutions through its subsidiaries: Kansas Gas Service, Oklahoma Natural Gas, and Texas Gas Service. This transition in leadership is poised to sustain ONE Gas’s commitment to customer service and compliance, further solidifying its market position.
