Message from the Board of Directors

Fellow Shareholders,In 2025, Occidental remained focused on delivering strong financial and operational results in a safe and responsible manner, strengthening Occidental’s balance sheet through debt reduction, practicing capital discipline in a dynamic macro-environment and, in turn, returning greater value to shareholders. Through robust governance practices, the Board oversaw a transformational year at Occidental and is pleased with the sustained operational outperformance, exceptional financial execution and significant debt reduction that management was able to achieve in 2025 despite a more challenging commodity price environment year-over-year. Furthermore, through our oversight of Occidental’s strategy—ranging from near-term priorities under the 2025 and 2026 capital programs to ambitious long-term goals for the company’s oil and gas operations and low-carbon initiatives—we continue to be excited about the opportunities to enhance shareholder value from Occidental’s optimized portfolio. EXECUTING TODAY: FOCUSED ON OPERATIONAL AND FINANCIAL PERFORMANCEWe closely monitor operational and financial performance, including stock price performance, both as directors and shareholders. In 2025, management focused on operational performance and cost efficiencies, resulting in record annual production while reducing capital and operating costs by approximately $575 million. More importantly, through exceptional dedication and awareness, Occidental employees delivered those results while achieving company-record safety performance with a TRIR of 0.07.(1)Occidental’s operational excellence drove strong annual financial results. For fiscal year 2025, the company generated $10.5 billion of operating cash flow and $4.3 billion of free cash flow before working capital.(2) This enabled management to reduce principal debt by approximately $4 billion in 2025 and, coupled with net proceeds from the OxyChem divestiture, supported an additional $7.0 billion in principal debt reduction as well as the Board’s recent authorization to increase the quarterly dividend by more than 8%. Since the December 2023 announcement of the CrownRock, L.P. acquisition, we have increased the common stock dividend by more than 44%. We recognize there is more work to be done in 2026. Collectively, the Board’s diverse backgrounds and experiences in the energy industry, environmental, safety and sustainability matters, finance, risk management and other pertinent areas will continue to help us assess Occidental’s performance and management’s commitment to technical excellence and capital discipline.POSITIONING FOR TOMORROW: COMMITTED TO OVERSIGHT OF PURPOSEFUL STRATEGIC TRANSFORMATIONIn 2025, Occidental navigated a critical strategic inflection point in determining to sell OxyChem, the company’s chemical business.(3) Overseen and approved by the Board, we believe this divestiture enabled management to further strengthen Occidental’s balance sheet and positioned the company to generate greater value from its high-return oil and gas assets. It also marked a significant milestone in a decade-long portfolio transformation during which Occidental completed strategic acquisitions and divestitures to high-grade its portfolio and reduce risk while building a 16.5 billion barrel of oil equivalent (BOE) resource base—up from approximately 8 billion BOE in 2015.Occidental continues to develop and advance low-carbon solutions in support of its business and sustainability goals. For example, STRATOS, the company’s direct air capture facility in the Permian Basin, is expected to be online this year. We are proud of Occidental’s bold direct air capture and sequestration projects in support of U.S. energy independence via enhanced oil recovery and the sustainability of our and others’ businesses. APPRECIATIVE OF SHAREHOLDER FEEDBACKDuring the past year, Occidental continued to proactively engage with shareholders collectively representing a majority of shares outstanding, with independent director participation in several of these discussions. Feedback from these engagements is discussed at each regular Board meeting and has informed our viewpoints and decisions. We remain dedicated to regular and transparent engagement with shareholders and other stakeholders. We value your views and would like to hear from you. If you would like to write to the Board, you may address your correspondence to the Board of Directors, in care of the Corporate Secretary, Occidental Petroleum Corporation, 5 Greenway Plaza, Suite 110, Houston, Texas 77046. This year, we will continue to exercise disciplined oversight of Occidental’s strategy and risks in support of sustainable shareholder value creation in any market environment. Thank you for your continued trust in the Board and support of Occidental. We are grateful to serve on your behalf.
