Item 5.02     Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On April 30, 2026, Vicki Hollub, President and Chief Executive Officer (“CEO”) of Occidental Petroleum Corporation (“Occidental”), informed the Board of Directors of Occidental (the “Board”) of her decision to retire, effective as of June 1, 2026 (the “Transition Date”).  The Executive Compensation Committee of the Board determined that Ms. Hollub’s retirement as President and CEO will be treated as an eligible retirement under Occidental’s Retirement Policy (the “Retirement Policy”), and as provided in the Retirement Policy, Ms. Hollub and Occidental will enter into a separation and release agreement pursuant to which Ms. Hollub will receive the retirement benefits set forth in the Retirement Policy. Following her retirement as President and CEO, Ms. Hollub, who was elected as a member of the Board at Occidental’s 2026 Annual Meeting of Shareholders, will continue to serve as a member of the Board.

On April 30, 2026, as part of its management succession planning, the Board unanimously approved the appointment of Richard A. Jackson, 50, as Occidental’s President and CEO and as a member of the Board, in each case effective as of the Transition Date.

Mr. Jackson has over 25 years of experience in the oil and gas industry, holding a variety of technical and leadership roles. Mr. Jackson joined Occidental in 2003 and has served as Occidental’s Senior Vice President and Chief Operating Officer since October 2025. Mr. Jackson’s previous positions at Occidental include Senior Vice President and President of Operations for U.S. Onshore Resources and Carbon Management from October 2020 to October 2025.

In connection with his promotion to the position of President and CEO, Mr. Jackson’s base salary will be increased to $1,400,000 per year and his target annual cash incentive award will be increased to 150% of base salary, each effective on or about the Transition Date. Mr. Jackson will also receive a grant of restricted stock units valued at $6,000,000, which will vest in equal annual installments over a three-year period subject to Mr. Jackson’s continued service through the applicable vesting dates.

Mr. Jackson does not have any family relationships with any director, executive officer or person nominated or chosen to become a director or executive officer of Occidental, and there are no arrangements or understandings between Mr. Jackson and any other person pursuant to which he was selected as a director or appointed as an officer of Occidental. There are no related party transactions involving Mr. Jackson that are reportable under Item 404(a) of Regulation S-K.

Occidental Announces CEO Succession

Vicki Hollub to retire as President and CEO effective June 1, 2026; Occidental’s Board Names Chief Operating Officer Richard Jackson as her successor

HOUSTON — May 1, 2026 — Occidental (NYSE: OXY) today announced that its Board of Directors, as part of its management succession planning, has named Senior Vice President and Chief Operating Officer Richard Jackson to succeed Vicki Hollub as President and Chief Executive Officer upon her retirement. Hollub will retire effective June 1, 2026, following a distinguished career of leadership and service.

The Board also announced Jackson will join the Board of Directors, effective June 1, 2026. Hollub, who has served as CEO since 2016 and has been a Board member since 2015, will continue to serve on the company’s Board of Directors following retirement, ensuring continuity and ongoing strategic guidance.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years. Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition,” said Hollub. “I look forward to supporting Richard and the Board through my continued role as a director.”

“On behalf of the Board, I want to thank Vicki for her exceptional leadership and transformative contributions to Occidental,” said Board Chairman Jack Moore. “Richard is the right leader to guide the company into its next phase of our strategy.”

Jackson joined Occidental in 2003 in its Middle East operations. During his time at Occidental, he has held pivotal leadership and technical positions, including President of U.S. Onshore Oil and Gas, President of Low Carbon Integrated Technologies, General Manager of the Permian Delaware Basin and Enhanced Oil Recovery Oil and Gas, Vice President of Investor Relations, and Vice President of Drilling Americas. 

As Chief Operating Officer, Jackson has focused on delivering value through resource improvement and cost efficiency by improving well performance, focusing on organic development and operational execution, and applying innovative technology.


“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” said Jackson. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”
