In the wake of APA Corp.’s $4.5 billion acquisition of Callon Petroleum, APA is shuffling its leadership structure, the company said April 9.

“Building on the momentum of our recently closed acquisition, we are updating our leadership structure to better align with the evolving needs of our business,” said John J. Christmann, APA CEO. “Today’s changes will help advance important priorities of the APA strategy and create opportunities for continued leadership development within our organization.”

Steve Riney, president and CFO, will now oversee asset development functions, including APA asset teams, planning and land, in addition to continued oversight of finance functions.

“Restructuring the development function and its reporting will enable stronger alignment across development teams and financial functions,” the company said.

Riney was promoted to president and CFO in January 2024. Previously, he served as CFO since joining the company in 2015. Dave Pursell, executive vice president of development, has left the company as a result of the restructuring.

During Pursell’s tenure, he helped establish the “development functions as we transitioned to a centralized model and advised the company as we navigated numerous challenges over the last several years. We wish him the best in his future endeavors,” Christmann said.

Additionally, Ben Rodgers has been named senior vice president, finance and treasurer, reporting to Riney. In this new role, Rodgers will lead market strategies, treasury, accounting and tax. Rodgers joined APA in 2018 and previously served as senior vice president, treasurer, midstream and marketing.

Castlen Kennedy has been promoted to senior vice president, corporate affairs and marketing. Kennedy will report to Mark Maddox, executive vice president, administration.

In this role, she will continue to oversee corporate communications, government affairs and community partnerships, and will add oversight of oil and gas marketing, business excellence and Egypt joint venture business support. Kennedy joined APA in 2006.
