Nominees are

Independent

Average

6-10 years

Occidental’s governance policies require that independent directors comprise at least two-thirds of the members of the Board (a policy that exceeds New York Stock Exchange (NYSE) requirements). The Board has affirmatively determined that each of our Board’s director nominees, other than Ms. Hollub, is independent under NYSE standards. The average tenure of our Board’s non-employee director nominees is approximately 8.9 years, which we believe reflects a balance of company experience and new perspectives.

Corporate Governance Highlights

RELATING TO THE BOARD ► Independent Chairman of the Board ► Annual elections of the entire Board by a majority of votes cast (for uncontested elections) ► Demonstrated commitment to Board refreshment ► Tenure policy that seeks to maintain an average tenure of 10 years or less for non-employee directors ► Board committees composed entirely of independent directors ► Meaningful director stock ownership guidelines (6x annual cash retainer) with holding requirement ► Annual evaluations of the Board, each committee and individual directors ► One meeting dedicated to strategy discussions every year with an expanded management group, in addition to ongoing strategy oversight RELATING TO SHAREHOLDER RIGHTS ► Ability of shareholders to call a special meeting at a 15% threshold ► Ability of shareholders to propose an action by written consent at a 15% threshold ► Shareholder right to proxy access (3% for 3 years, up to 20% of the Board) ( 1) ► Confidential Voting Policy ► Nominating Policy to consider properly submitted shareholder-recommended director nominees ► No supermajority voting requirements ► Active independent director participation in and oversight of the shareholder engagement program

Proxy Statement Summary

Executive Compensation Program Summary

The Compensation Committee strives to maintain a competitive compensation program that will attract, retain and motivate outstanding

executives by providing incentives to reward them for superior performance that supports Occidental’s long-term strategic objectives,

across the commodity price cycle.

The primary elements of our executive compensation program consist of base salary, an annual cash incentive (ACI) award and long-term

incentive (LTI) awards. Our CEO’s compensation is heavily weighted toward long-term incentive awards, of which 60% were conditioned

on Occidental’s three-year relative total shareholder return (TSR) and absolute cash return on capital employed (CROCE) performance.

Allocation of Direct Compensation Elements

A substantial majority of named executive officer (NEO) compensation is dependent on performance. 90% of Ms. Hollub’s (and an average

of 84% of the other NEOs’) target direct compensation opportunity is variable, or at risk. The ultimate value of at-risk compensation is

primarily dependent on company performance outcomes and Occidental’s stock price performance .

Proxy Statement Summary

Highlights of Executive Compensation Program

Policies and Practices

The 2025 executive compensation program for the NEOs includes many best-practice features that are intended to enhance the alignment

of compensation with the interests of Occidental’s shareholders.

WHAT WE DO ✓ Pay for Performance. ✓ Listen to Shareholder Feedback. ✓ Clawback in the Event of Misconduct. ✓ Emphasize Stock Ownership With Ownership Guidelines and Holding Requirements. ✓ Monitor Compensation Program for Risk. ✓ Use Double-Trigger Equity Vesting for Equity Awards. ✓ Use Relative and Absolute Performance Measures for Equity Awards.

WHAT WE DON’T DO ✗ No Dividend Equivalents on Unvested Performance Awards. ✗ No Hedging or Derivative Transactions of Company Equity Securities. ✗ No Golden Parachute Payments. ✗ No Repricing of Stock Options.

Say-on-Pay Vote

At the 2021, 2022, 2023, 2024 and 2025 annual meetings, Occidental’s Say-on-Pay (SOP) vote received support from greater than 94% of the total votes cast—with support at approximately 97% for four of those five meetings. The Compensation Committee views these results as a strong endorsement by shareholders of the current structure of the company’s executive compensation program. Through shareholder engagement, shareholders and other stakeholders have continued to express support for having a significant portion of CEO and other NEO compensation be variable, or at risk, and for enhancements to our proxy statement disclosure on compensation-related matters. Such feedback prompted disclosure of the threshold and maximum targets for the 2025 ACI award financial metrics. Given the strong level of support shown, the Compensation Committee did not make any changes to the 2025 compensation program in specific response to the SOP vote. The Compensation Committee values shareholder feedback and, equipped with such feedback, will strive to continue to enhance alignment of executive compensation with the interests of Occidental’s shareholders.

Shareholder Engagement

Occidental is committed to regular and transparent communication and engagement with its shareholders and other stakeholders.

In 2025 , we engaged with shareholders representing >60% of our outstanding shares* * Based on average shares outstanding in 2025 . HOW WE ENGAGED WITH OUR SHAREHOLDERS: ► We proactively engage with our largest shareholders throughout the year, including broad-based engagements in the fall/winter to discuss governance, environmental, sustainability, social and other matters, and in advance of the annual meeting to discuss agenda items and any other topics of interest. ► We regularly conduct roadshows targeting engagement with specific investors and participate in industry conferences to engage with a broad group of investors. ► We also engage with investors through virtual and in-person meetings, phone calls and emails . ► We periodically meet with investor advocacy groups, including shareholder proponents , to better understand their areas of focus and expectations. ► We regularly report our shareholders’ views to the Board and respond to feedback. ► Independent directors participated in several of our engagement meetings. ► The Board’s Sustainability and Shareholder Engagement Committee oversees our shareholder engagement program and provides an avenue for shareholder feedback to be communicated directly to the Board. TOPICS DISCUSSED WITH OUR SHAREHOLDERS: ► OxyChem divestiture ► Cash flow and shareholder return priorities, including deleveraging ► Capital spending and activity levels ► Oil and gas inventory depth, well performance and operational differentiation ► Midstream outlook ► STRATOS progress and DAC economics ► OLCV updates and cash flow potential ► Portfolio optimization ► Geopolitical and regulatory risks ► Board oversight of the company’s strategy and risk ► Board composition and refreshment ► Design and structure of our executive compensation program ► Climate, sustainability and human capital matters

Meaningful Dialogue with Shareholders. Occidental uses engagement with shareholders, as well as other stakeholders, to have

meaningful dialogue on governance, sustainability and other matters. During our recent series of off-season engagements in the fall/winter,

we discussed a range of governance-related items, including Board oversight of risk and strategy.

We also continued to discuss climate and sustainability matters, including updates on STRATOS, our direct air capture facility in the

Permian Basin, as well as our sustainability practices and reporting. These conversations give us a better understanding of shareholder

and stakeholder interests and have helped inform our sustainability strategy and enhance climate-related disclosures .

ELECTION OF

DIRECTORS

THE BOARD OF

DIRECTORS

RECOMMENDS A

VOTE “FOR” EACH

OF THE DIRECTOR

NOMINEES.

Director Nominations

The Board is committed to recruiting and nominating directors for election who will collectively provide the Board with the necessary

breadth of skills, backgrounds and experiences to meet Occidental’s ongoing needs and support oversight of its business strategy,

risks and priorities. In recommending candidates for election to the Board, the Corporate Governance and Nominating Committee

(the Governance Committee) evaluates a candidate’s character; judgment; skill set and experience in light of Occidental’s current and

future needs and strategic priorities; independence; other time commitments, including other public and private company board

memberships; and any other factors that the Governance Committee deems relevant. In addition, in determining whether to recommend

incumbent directors for reelection to the Board, the Governance Committee also reviews and considers tenure; the director’s board and

committee meeting attendance and participation; the level of support that the director’s nomination received at the most recent annual

shareholders’ meeting (if applicable); and the well-roundedness of the Board as a whole.

The Board is committed to ongoing and thoughtful refreshment of its membership and strives to maintain an appropriate balance of tenure,

backgrounds and skills on the Board. The Board believes that this ongoing refreshment, which has resulted in one- third of the independent

directors beginning their service at Occidental within the past five years, further aligns Board composition with the needs of Occidental as

our business evolves over time and encourages regular consideration of fresh viewpoints and perspectives. The Board also believes that,

over time, directors develop an enhanced understanding of Occidental and an ability to work effectively as a group. Accordingly, the Board

aims to have directors with a mix of tenures represented.

In February 2026 , the Governance Committee recommended to the Board, and the Board approved, the nomination of the 10 persons

whose biographies appear below to serve for a one-year term ending at the 2027 Annual Meeting, but in any event, until his or her

successor is elected and qualified, unless ended earlier due to his or her death, resignation, disqualification or removal from office. The

Board has no reason to believe that any of the Board’s nominees would be unable or unwilling to serve as a director if elected. However,

should any of our Board’s nominees be unable or unwilling to stand for election at the time of the 2026 Annual Meeting, proxies may be

voted for a substitute nominee selected by the Board, or the Board may reduce the number of directors.

Pursuant to Occidental’s By-laws, in an uncontested election, the affirmative vote of a majority of votes cast with respect to each director

nominee will be required for the nominee to be elected, meaning that the number of votes cast “FOR” a director must exceed the number

of votes cast “AGAINST” that director. Your broker will not vote your shares on this proposal unless you give voting instructions, and

abstentions and broker non-votes have no effect on the vote. Under the resignation guidelines in Occidental’s Corporate Governance

Policies (as defined below), any nominee for director who does not receive a greater number of votes “FOR” his or her election than votes

“AGAINST” in an uncontested election is expected to promptly tender his or her resignation.

Corporate Governance

Occidental’s corporate governance policies (the Corporate Governance Policies) establish Occidental’s governance framework. The

Corporate Governance Policies address the structure and operation of the Board, including matters related to director independence;

tenure; outside board memberships; the role of the Board’s Independent Chairman; director stock ownership; and Board, committee and

individual director performance evaluations. In addition to the Corporate Governance Policies, the Board has established other stand-alone

governance policies, including a policy on shareholder rights plans, a confidential voting policy and an independent compensation

consultant policy. Occidental’s governance policies are reviewed and updated periodically, in light of changing regulations, evolving best

practices and shareholder feedback. The Corporate Governance Policies and other governance policies are available on our website at

www.oxy.com/investors/governance.

Corporate Governance

Board Evaluation Process

Led by the Governance Committee, the Board conducts a robust annual evaluation of its performance and the performance of each of the

Board’s committees and the individual directors. The Governance Committee believes that board evaluations are a critical tool in assessing

the composition and effectiveness of the Board, its committees and its members and present an opportunity to identify areas of strength

and areas capable of improvement. The annual Board evaluation includes an assessment of, among other things, whether the Board and

its committees have the necessary diversity of skills, backgrounds and experiences to meet Occidental’s needs. As part of this process,

directors are asked to identify which board candidate skills and attributes should be prioritized for the Board’s ongoing director recruitment.

The evaluation process also includes ongoing discussion and feedback from directors throughout the year regarding the Board’s and its

committees’ effectiveness. The Governance Committee annually considers the format of its evaluation processes, which historically

have intentionally included different formats, such as questionnaires, individual director interviews and the use of a third-party facilitator.

The 2025 Board evaluation process is summarized below.

1	DETERMINE THE PROCESS	In 2025 , the Governance Committee recommended, and the Board approved, Board evaluations through the use of: (i) written questionnaires, (ii) a skills matrix, and (iii) individual director interviews. This process has encouraged candid feedback from directors and continued to promote productive discussions.
2	CONDUCT EVALUATIONS	The Board and committee questionnaires solicited feedback related to Board and committee effectiveness and performance; agenda topics and materials; skills; leadership; and, at the Board level, matters related to strategy. The questionnaires also included open-ended questions that prompted each director to reflect and comment on his or her own individual performance and contributions to the Board. The Chair of the Governance Committee interviewed each director to discuss his or her questionnaire responses and to solicit additional feedback.
3	ANALYZE THE RESULTS	In late 2025 , the aggregated results of the questionnaires and feedback from the director interviews were reviewed and discussed at a meeting of the Governance Committee. Each committee reviewed its individual results, and the Chair of the Governance Committee led the Board in a discussion of the overall findings at a meeting of the full Board.
4	TAKE RESPONSIVE ACTION	As part of its analysis of the evaluation results, the Board and management determined appropriate responsive actions to be implemented over the next year that are intended to address areas that were identified as capable of improvement. At the Board level, this process continued to provide valuable insight for Board succession planning, and preferred director candidate qualifications, as well as the ongoing effectiveness of Board and committee meeting practices. It also contributed to increasing the amount of time allotted for executive sessions. At the committee level, it has supported agenda changes—to allow more time for discussion—and committee chairperson rotations.

Director Selection and Recruitment

Pursuant to the Board’s Nominating Policy, the Governance Committee considers director candidates recommended by shareholders as

discussed further on page 70 . In recent years, the Board has identified director candidates through the use of independent search firms,

third-party recommendations and the recommendations of directors. For a discussion of the factors that the Governance Committee

considers in recommending candidates for election to the Board, see “Proposal 1: Election of Directors—Director Nominations”

on page 13 .

Corporate Governance

Process for Identifying and Evaluating

Directors and Nominees

The Governance Committee reviews with the Board, on at least an annual basis, the current composition of the Board. Based on its annual

review, the Committee recommends to the Board the general selection criteria for director nominees, screens potential director candidates

and recommends the slate of director nominees for election to the Board at the company’s annual meeting of shareholders in light of the

current and anticipated needs of the Board and its committees. The Board also periodically reviews the status of director recruitment.

Board Refreshment and Succession Planning

We believe that thoughtful Board refreshment and proactive director succession planning is an integral part of the company’s ability to

deliver on its long-term strategy.

Board Refreshment

To have an appropriate balance of new perspectives with the institutional knowledge contributed by our longer-serving directors, the

Committee periodically reviews best practices to enhance the Board’s refreshment process. Our Corporate Governance Policies

incorporate refreshment mechanisms, including a tenure policy that seeks to maintain an average tenure of 10 years or less for

Occidental’s non-employee directors and resignation guidelines in an uncontested election.

Succession Planning and Director Recruitment Process

In anticipation of retirements as well as evolving strategic needs for different skills and capabilities, the Committee conducts proactive,

strategy- and risk-driven director succession planning. Director succession planning and recruitment processes are designed to be

responsive to anticipated future needs in light of business, industry and market dynamics and to yield an appropriate balance of skills,

backgrounds, experiences and tenure to effectively support and oversee the implementation of our long-term strategy.

The Committee follows a multi-step approach to succession planning and the director recruitment process to identify and evaluate potential

director candidates:

1	2	3	4
• The Governance Committee evaluates Board composition at least annually and determines skills and qualifications desirable for new directors based on the company’s short- and long-term strategies, opportunities and challenges as well as director feedback from the annual Board evaluation process.	• Based on its assessment of Board composition, the Governance Committee identifies certain skill sets and attributes to prioritize and guide the Governance Committee’s and Board’s search. • A robust pool of prospective candidates is identified using multiple sources.	• The Governance Committee reviews available information on prospective nominees to evaluate candidate experience, skills and qualifications, independence, conflicts of interest, background, fit and other commitments. • Committee and Board members meet with qualified top candidates.	• The Governance Committee recommends prospective director candidate(s) to the Board for approval. • The Board recommends director nominees to shareholders and shareholders vote on such nominees at the annual meeting.

Proxy Access for Shareholder-Nominated Director Candidates

Independent Board Leadership Structure

Occidental’s By-laws provide for the Board to annually elect one of its independent directors to be Chairman of the Board.

Responsibilities of Independent Chairman

Director Engagement

Director Education and Orientation

Directors are provided with continuing education, including business-specific learning opportunities through site visits and briefing sessions

led by internal experts or third parties on topics that are relevant to Occidental. During 2025, these sessions included continued briefings

on business strategy, capital allocation considerations and key risks, as well as updates on both artificial intelligence (AI) projects and

STRATOS progress, research and development learnings and competitive and market dynamics. In addition, throughout 2025,

management, including Government Affairs leadership, provided briefings on legislative, regulatory and public‑policy developments

relevant to Occidental’s operations and their potential impacts on the company.

Directors are also encouraged to attend additional continuing education programs designed to enhance the performance and

competencies of individual directors and the Board. For example, in 2025, directors attended external continuing education

programs and conferences addressing a broad range of topics, including governance matters, enterprise risk management and

artificial intelligence.

Each new director is provided with extensive onboarding materials and information covering director responsibilities, corporate governance

practices and policies, business strategies, leadership structure and long-term plans concerning Occidental in order to enable the individual

to perform the duties of a director. Orientation also includes individualized meetings with senior management and other key leaders.

Participation in regular Board and committee meetings also provides new directors with a strong foundation for understanding Occidental’s

business, connects directors with members of management and accelerates their effectiveness. Directors have access to additional

orientation and educational opportunities as they accept new or additional responsibilities on the Board or its committees. For example,

each new chairperson also receives committee-specific onboarding (inclusive of meetings with management liaisons and other members of

management, as applicable) and information to support their leadership role.

Director Attendance

The Board of Directors held eight meetings in 2025 , one of which was principally devoted to strategic review. Each of the directors

attended 100% of the aggregate number of meetings of the Board and of the Board committees on which he or she served. All of the

directors then serving on the Board attended the 2025 Annual Meeting of Shareholders. Attendance at the Annual Meeting of Shareholders

is expected of directors as if it were a regular meeting of the Board.

Executive Sessions of the Independent Directors

The independent directors regularly meet in executive sessions at which no members of management are present. The independent

directors held five executive sessions in 2025 . The Board’s Independent Chairman chaired the executive sessions.

Strategy Oversight

The Board and its committees provide strategic guidance to management and oversight of Occidental’s business strategy throughout the

year. Various elements of strategy are discussed at every Board meeting, as well as at many meetings of the Board’s committees.

Each year, the Board’s strategy oversight includes a dedicated discussion of significant risks and opportunities at the Board’s strategic

planning meeting, which allows for an in-depth annual assessment of such risks and opportunities facing Occidental. At the 2025 strategic

planning meeting, the Board continued its focus on the company’s assets and enabling technologies, as well as associated challenges and

opportunities, and reviewed other important topics, such as the company’s existing uses of AI and potential opportunities for generative AI

with respect to data analytics, as well as the associated risks. The Board also reviewed strategic, risk, market and other considerations

relating to the OxyChem divestiture, including the strategic rationale for the transaction and the anticipated use of proceeds. Also, while

Occidental’s low-carbon ventures and carbon management platform is a topic that is a focus for the full Board throughout the year, it has

continued to be a key topic of our annual strategic planning meeting in recent years. Given the variety of topics reviewed and the depth at

which they are discussed, the annual strategic planning meeting affords the Board the opportunity to meet with expanded members of

management, including internal subject-matter experts.

Risk Oversight

Risk oversight occurs at both the Board and committee levels. The Board is responsible for overseeing Occidental’s policies and

procedures with respect to risk management, and it has empowered its committees with oversight of specific, material risks within each

committee’s area of focus. Each of the Board’s committees is integral to the control and compliance aspects of risk oversight by the Board.

Each committee meets regularly with management to review, as appropriate, compliance with existing policies and procedures and to

discuss changes or improvements that may be required or desirable. The frequency of committee meetings is intended to allow each

committee adequate time for in-depth review and discussion of matters associated with its areas of responsibility. Each committee regularly

reports to the Board regarding the committee’s discussion of issues and findings, as well as to make recommendations regarding

appropriate changes or improvements.

●	OVERSIGHT OF CYBERSECURITY
Occidental recognizes the importance of monitoring cyber risk. At the management level, Occidental’s Chief Information Officer (CIO), who has over 20 years of IT and cybersecurity experience, heads the team responsible for implementing and maintaining cybersecurity and data protection practices across Occidental’s operations and reports directly to the President and CEO. Occidental’s CIO regularly reviews risk management measures and the overall cyber risk strategy implemented and maintained by the company. The CIO receives regular updates on Occidental’s cybersecurity program and monitors the prevention, detection, mitigation and remediation of cybersecurity incidents through reports from the company’s cybersecurity leaders, each of whom is supported by a team of trained cybersecurity professionals. In addition to Occidental’s extensive in-house cybersecurity capabilities, Occidental engages assessors, consultants, auditors or other third parties when necessary to assist with assessing, identifying and managing cybersecurity risks. At the Board level, the Audit Committee oversees Occidental’s IT security programs, including cybersecurity, which includes review of possible external threats and potential mitigations. In addition to Audit Committee oversight, the Board reviews the company’s cybersecurity program at least annually. In that review, the CIO briefs the full Board on cybersecurity and data protection matters, including analysis and review of the measures implemented by the company to identify and mitigate cybersecurity risks. Occidental also has protocols by which material cybersecurity incidents, if any, are to be reported to the Audit Committee and/or the Board, as appropriate. In addition to the above, Occidental’s cybersecurity practices are reviewed as part of the company’s standard general IT controls. Business network and industrial control systems (ICS) cybersecurity risks are handled by separate and dedicated Occidental teams and are incorporated into Occidental’s ERM program.
●	OVERSIGHT OF HUMAN CAPITAL AND CULTURE
Occidental understands the importance of attracting, retaining and motivating top talent at all levels within the company and strives to create an environment where employees’ differences are appreciated, celebrated and encouraged. At the management level, the company has a dedicated Vice President of Human Resources (HR) Strategy who, along with her team, is responsible for providing strategic guidance and support to business leaders and executives in furtherance of these goals. The HR department supports several voluntary Employee Resource Groups, which promote peer engagement and education to help advance inclusion and a sense of belonging of employees with common interests. At the Board level, the Sustainability and Shareholder Engagement Committee reviews and discusses the company’s human capital strategy at least annually. In connection with this review, in February 2025, the then-Vice President of HR Strategy and Services updated the Committee regarding employee demographics, employee engagement, workforce development and other initiatives. The full Board also discusses senior management succession planning at least annually.
●	OVERSIGHT OF HSE & SUSTAINABILITY
Occidental appreciates the importance of HSE and sustainability matters and the impact related risks may have on the company’s operational and financial performance. At the management level, Occidental’s Vice President of Environmental and Sustainability leads the team responsible for managing the company’s environmental performance, HSE and sustainability reporting, and environmental and sustainability programs. At the Board level, the full Board oversees HSE and sustainability matters, including those with respect to climate, as an integral part of its oversight of Occidental’s strategy and key risks. These matters are inherent to the company’s strategic plans and, accordingly, are incorporated into Board meeting presentations and discussions. The Board’s committee structure is designed to provide the Board and its committees with the appropriate oversight of relevant HSE matters as well as relevant sustainability matters. The Environmental, Health and Safety Committee oversees and reviews the status of HSE performance, including the company’s Operating Management System and compliance with applicable laws and regulations. It also reviews results of internal compliance reviews and remediation projects, among other things. The Sustainability and Shareholder Engagement Committee assists the Board in overseeing environmental, social and sustainability matters, including climate-related risks and opportunities, and external investor-oriented reporting on the same. It reviews and monitors climate- and other sustainability-related public policy trends and related regulatory matters, and it also oversees Occidental’s sustainability and social responsibility programs, policies and practices, including the Human Rights Policy.

Corporate Governance

Shareholder Engagement

Occidental is committed to regular and transparent communication and engagement with its shareholders and other stakeholders.

In November 2025, the U.S. Securities and Exchange Commission (SEC) announced that it would no longer substantively review and respond to most no-action requests seeking the exclusion of shareholder proposals under Rule 14a-8 of the Exchange Act of 1934. Following this announcement, after careful consideration and consultation with external legal counsel and review of Rule 14a-8 and prior SEC guidance on its application, Occidental determined that it had reasonable bases to exclude two shareholder proposals submitted by shareholder proponents for the 2026 Annual Meeting. Occidental’s bases for exclusion are detailed in the letters submitted on behalf of Occidental to the staff of the Division of Corporation Finance dated December 29, 2025, which can be accessed at https://www.sec.gov/rules-regulations/shareholder-proposals/2025-2026-responses-issued-under-exchange-act- rule-14a-8. Members of management engaged with both shareholder proponents regarding these proposals and hope to continue the dialogue in the future.

Communications with Directors

Shareholders and other interested parties may communicate with any director by sending a letter to the director’s attention in care of

Occidental’s Corporate Secretary, Occidental Petroleum Corporation, 5 Greenway Plaza, Suite 110, Houston, Texas 77046. The Corporate

Secretary opens, logs and forwards all such correspondence (other than advertisements or other solicitations) to directors unless a director

has requested that the Corporate Secretary forward correspondence unopened.

Other Governance Matters

Related Party Transactions

Pursuant to Occidental’s Conflict of Interest Policy and Code of Business Conduct, each director and executive officer has an obligation

to avoid any activity, agreement, business investment or interest, or other situation that could be construed either as divergent from or

in competition with Occidental’s interest or as an interference with such person’s primary duty to serve Occidental, unless prior written

approval has been granted by the Audit Committee. All potential conflicts of interest must be reported to a designated compliance

officer. A summary of the Conflict of Interest Policy is included in Occidental’s Code of Business Conduct which can be found at

www.oxy.com/investors/governance.

Pursuant to Occidental’s written policy on related party transactions, the Governance Committee reviews relationships and transactions

in which Occidental and its directors, executive officers or their immediate family members participate if the amount involved exceeds

$120,000. To help identify related party transactions, each director and executive officer completes an annual questionnaire that requires

disclosure of any transaction between Occidental and the director or executive officer or any of his or her affiliates or immediate family

members. Additionally, the accounting department reviews Occidental’s financial records for payments made to, or received from, related

parties and the entities with which the related parties are affiliated, and reports any identified transactions to the legal department.

The Governance Committee reviews and approves, ratifies or rejects identified related party transactions. In approving, ratifying or

rejecting a related party transaction, the Governance Committee considers, among other factors it deems appropriate, whether the

transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar

circumstances and the extent of the related party’s interest in the transaction.

Pursuant to the policy, the Governance Committee approved and/or ratified transactions that qualified as related party transactions,

including the following. Occidental entered into a purchase and sale agreement with Berkshire Hathaway Inc. (Berkshire), a greater

than 5% beneficial owner of Occidental’s common stock, pursuant to which Berkshire agreed to acquire all of the issued and

outstanding equity interests in OxyChem in an all‑cash transaction valued at approximately $9.7 billion, subject to customary

purchase price adjustments. The transaction closed on January 2, 2026. Additionally, Corey N. Hardegree, the son-in-law of Jeff F.

Simmons, Senior Vice President and Chief Petrotechnical Officer, is employed by Occidental as a lead production optimization

engineer for the company’s domestic oil and gas business. His total compensation for 2025 (consisting of his annual base salary,

annual bonus and stock-based compensation) was less than $375,000 . He also participated in the general welfare and benefit plans

of Occidental. Mr. Simmons did not participate in the hiring of his son-in-law and does not participate in the performance evaluations

or compensation decisions regarding his son-in-law.

Non-Employee Director Compensation

The Governance Committee periodically reviews non-employee director compensation and makes recommendations regarding changes

to the program to the Board. The Governance Committee last reviewed non-employee director compensation in May 2024 with the

assistance of Meridian as its independent compensation consultant. Meridian performed a robust review of Occidental’s non-employee

director compensation program, which included a detailed comparison of Occidental’s non-employee director compensation program

and practices against those of Occidental’s peer companies, the largest 200 companies in the S&P 500 and the full set of companies

in the S&P 500. After careful consideration and discussion, the Governance Committee determined to restore non-employee director

compensation to 2019 levels, except for the annual equity award for the Chairman of the Board, which was increased to be more

competitive with market non-executive chair pay practices. With those changes, the Governance Committee believes the program

is competitive and aligned with market practices. Therefore, it decided to not make any changes to the program for the 2025 - 2026 term.

Director Compensation Program

The non-employee directors receive a combination of cash, in the form of an annual retainer payable on a monthly basis, and stock-based

compensation. Occidental does not provide option awards, non-equity incentive awards or retirement plans for non-employee directors.

The Independent Chairman of the Board and the committee chairs receive additional compensation for their service due to the increased

responsibilities that accompany these positions. Ms. Hollub does not receive any compensation for her service as a director.

The following table describes the components of the non-employee director compensation program for the 2025 - 2026 term:

Compensation Element
Annual Cash Retainer	$ 125,000 for non-employee directors
	$ 155,000 for Chairman of the Board
Annual Equity Award	$ 225,000 for non-employee directors
	$ 405,000 for Chairman of the Board
Board or Committee Meeting Fees	None
Committee Chair Additional Annual Equity Award	$ 25,000 for each committee chaired

Annual Equity Award

The Board believes that director and shareholder interests should be aligned over the long term. In furtherance of this objective, the

majority of non-employee director compensation is equity-based compensation. Directors may elect to receive their annual equity award

in shares of common stock or in deferred common stock units.

Common Stock Award. Pursuant to the terms of the award, the director receives shares of common stock that are fully vested at grant

but subject to transfer restrictions. 50% of the shares may not be sold or transferred until the earlier of the third anniversary of the grant

date or the date of the director’s separation from service, and the remaining 50% may not be sold or transferred until the date of the

director’s separation from service; provided, however, that all of the shares become transferable in the event of certain change in

control events.

Deferred Stock Unit Award. Pursuant to the terms of the award, the director receives deferred stock units that are fully vested at grant but

subject to deferred settlement. Each deferred stock unit is equivalent to one share of common stock and payable in shares of common

stock upon the satisfaction of the deferral period. 50% of the deferred stock units are payable upon the earlier of the third anniversary

of the grant date or the date of the director’s separation from service, and the remaining 50% are payable on the date of the director’s

separation from service; provided, however, that all of the deferred stock units are payable in the event of certain change in control events.

All Other Compensation

Directors are eligible to participate in the Occidental Petroleum Corporation Matching Gift Program, which matches contributions made

by employees and directors to certain qualified, eligible charitable organizations. The limit for such matching contributions is $7,500.

Occidental also reimburses non-employee directors for expenses related to their Board service, including hotel, airfare, ground

transportation and meals.

Stock Ownership Guidelines

Each non-employee director is expected to beneficially own a number of shares of common stock or deferred stock units of Occidental

having a market price equal to at least six times the annual cash retainer for non-employee directors within five years of his or her election

to the Board. A director who does not meet the minimum ownership guideline may not sell any shares of Occidental common stock until

he or she meets the ownership guideline and would continue to meet the ownership guideline following any such sale. As of March 1,

2026 , each of the non-employee directors was in compliance, or on track to comply, with these guidelines.

Robert M. Shearer	$ 125,000	$ 225,020	$ —	$350,020

(1) Equity awards are granted to each non-employee director on the first business day following the annual meeting. Prior to the grant date, directors are given

the option to receive their annual equity awards as shares of common stock or as deferred stock units, as described above. In 2025 , Ms. O’Neill and Secretary

Gutierrez elected to receive deferred stock units, while all other non-employee directors elected to receive shares of common stock. The grant date fair value

reported in the table is calculated by multiplying the number of shares of common stock granted by a price per share of $38.81, the closing price of Occidental’s

common stock on the NYSE on May 5, 2025. These grants are made in whole shares, with fractional share amounts rounded up to the nearest whole share.

For information regarding the total number of restricted shares and deferred stock units held by each director, see the Beneficial Ownership of Directors

and Executive Officers table on page 65 .

TO APPROVE NAMED

EXECUTIVE OFFICER

COMPENSATION

Occidental is submitting this proposal to its shareholders for an advisory vote to approve the compensation of its named executive officers

(Say-on-Pay vote) as disclosed in this proxy statement pursuant to Section 14A of the Exchange Act. At our 2023 annual meeting,

Occidental’s shareholders approved, on an advisory basis, a frequency of every year for casting advisory votes to approve named

executive officer compensation. The next Say-on-Pay vote is expected to occur at our 2027 annual meeting.

The executive compensation program for the named executive officers includes many best-practice features that are intended to enhance

the alignment of compensation with the interests of Occidental’s shareholders. The executive compensation program is described in the

Compensation Discussion and Analysis (CD&A) section beginning on page 35 of this proxy statement.

The Compensation Committee strives to maintain a compensation program that will attract, retain and motivate outstanding executives by

providing incentives to reward them for strong performance that supports Occidental’s long-term strategic objectives and is competitive

with industry practices. The executive compensation program is intended to:

► Align with shareholder interests and be responsive to shareholder feedback;

► Preserve performance accountability across the commodity price cycle;

► Build and encourage long-term share ownership;

► Provide a consistent retention incentive;

► Be straightforward and transparent for the benefit of executives and shareholders;

► Match or surpass prevailing governance standards for performance-based compensation; and

► Use relative and absolute performance measures for equity awards.

The Board recommends that shareholders support the following resolution for the reasons described in the CD&A:

RESOLVED , that the shareholders approve, on an advisory basis, the compensation of Occidental’s named executive officers for 2025 , as

set forth in the CD&A, Summary Compensation Table and the other tables and narrative disclosures regarding named executive officer

compensation set forth in this proxy statement.

A majority of the shares of common stock present in person or by proxy at the 2026 Annual Meeting and entitled to vote on this proposal

must vote “FOR” the proposal to approve it. Your broker may not vote your shares on this proposal unless you give voting instructions.

Abstentions have the same effect as votes cast “AGAINST” the proposal. Broker non-votes have no effect on the vote. As in past years,

your vote will not directly affect or otherwise limit or enhance any existing compensation or award arrangement of any of our named

executive officers, but the outcome of this advisory say-on-pay vote will be taken into account by the Compensation Committee in making

future compensation decisions.

Compensation Discussion and Analysis

Executive Summary

2025: Operational Excellence, Financial Resilience and Strategic Execution

Given the discipline and hard work of Occidental’s employees, the company delivered exceptional operational performance while reducing

costs and enhancing efficiency across Occidental’s business units and corporate functions. Occidental set a new annual production record

of 1.43 million barrels of oil equivalent per day, exceeding the high end of its guidance, while spending $300 million (1) less in capital

expenditures than originally planned. Occidental reduced operating expenses by $275 million 1 and achieved the company’s lowest lease

operating expense per barrel of oil equivalent since 2021. This supported strong financial results and enabled the Board to increase the

dividend by more than 8% to 26 cents per share effective as of the April 2026 common dividend.

Occidental also excelled in strategic execution throughout the year, positioning the portfolio to maximize value by increasing exposure to

short-cycle, high-return assets while also advancing major projects aimed at delivering sustainable returns through the cycle. As part of its

business strategy, Occidental completed the sale of its chemical business, OxyChem, in early January 2026 to further strengthen the

company’s balance sheet through additional debt reduction and position it to deliver greater value from the company’s robust portfolio of oil

and gas assets.

Despite challenging market conditions and a volatile commodity price environment, senior leadership delivered total spend per barrel and

free cash flow before working capital that surpassed 2025 targets. This short-term execution laid important groundwork for the company’s

2026 capital plan and operational goals.

Pay-for-Performance Driven

For 2025 , the Compensation Committee remained pay-for-performance driven, with an appropriate mix of short-term and long-term

incentive compensation. This resulted in significant at-risk pay for Ms. Hollub at 90% and the other NEOs at an average of 84% . The

Compensation Committee will continue to responsibly oversee the effectiveness of Occidental’s executive compensation structure for

strong alignment among executive officer compensation, company performance and the shareholder experience.

Occidental’s directors and management remain dedicated to regularly engaging with shareholders and other stakeholders and soliciting

their feedback on compensation, governance and other matters of interest. Throughout 2025 and the beginning of 2026, consistent with

prior years, members of management participated in these discussions, with active independent director participation either directly or

through oversight of the shareholder engagement program. This engagement supported the following Compensation Committee actions

driven by shareholder feedback:

What We Heard	How We Responded
Maintain strong pay-for-performance alignment	Continued to use relative TSR and absolute CROCE metrics for PSUs
	Maintained the performance-based portion of the LTI program at 60%
Evaluate use of CROCE as a metric for both the ACI and LTI awards	Determined to use free cash flow before working capital as a performance metric for the 2025 ACI award in place of CROCE
Disclose threshold and maximum goals for ACI financial metrics	Provided additional transparency around the ACI financial metrics (i.e., threshold and maximum goals)
Appreciate inclusion of sustainability metric	Maintained metric to drive near-term execution of sustainability strategy; aligned LCV efforts (5%) with Strategic/Innovation goals

Compensation Discussion and Analysis

Governance Features of the Executive

Compensation Program

The 2025 executive compensation program for the NEOs includes many best-practice features that are intended to enhance the alignment

of compensation with the interests of Occidental’s shareholders.

WHAT WE DO ✓ Pay for Performance. A substantial majority of NEO compensation is performance-based. The Compensation Committee reviews the metrics underlying the LTI program and ACI awards annually to evaluate their continued alignment with Occidental’s business priorities. ✓ Listen to Shareholder Feedback. The Compensation Committee reviews and considers shareholder feedback. For example, it contributed to the Compensation Committee’s decisions to use free cash flow before working capital as a performance metric for the 2025 ACI award in place of CROCE, disclose the threshold and maximum levels for the financial metrics and maintain the sustainability metric for such award. Shareholder feedback also informed the Compensation Committee’s decision to continue the performance-based allocation of the 2025 LTI program at 60%. ✓ Clawback in the Event of Misconduct. Occidental maintains a clawback policy which is intended to comply with the requirements of NYSE Listing Standard 303A.14 implementing Rule 10D-1 under the Securities Exchange Act. In addition, the Compensation Committee has the authority to clawback ACI payouts and both time- and performance-based LTI awards for violations of Occidental’s Code of Business Conduct and related policies. ✓ Emphasize Stock Ownership With Ownership Guidelines and Holding Requirements. CROCE and TSR awards are payable in shares of common stock and the net shares received for each vested RSU award are subject to a two-year holding period. In addition, the NEOs (as well as other officers) are subject to meaningful stock ownership guidelines, ranging from two to six times the officer’s annual base salary, and a holding requirement until such guidelines are met. ✓ Monitor Compensation Program for Risk. The executive compensation program includes multiple features that are intended to appropriately mitigate excessive risk-taking. The Compensation Committee conducts an annual assessment of our executive compensation program to identify and minimize, as appropriate, any compensation arrangements that may encourage excessive risk-taking. ✓ Use Double-Trigger Equity Vesting for Equity Awards. Pursuant to the Amended and Restated 2015 Long-Term Incentive Plan (LTIP), equity awards vest in the event of a change in control only if there is also a qualifying termination of employment. ✓ Use Relative and Absolute Performance Measures for Equity Awards. Performance equity is earned based on both relative shareholder returns and absolute financial returns, with TSR awards capped at target if Occidental’s absolute TSR is negative and CROCE awards measured against an absolute performance target.

WHAT WE DON’T DO ✗ No Dividend Equivalents on Unvested Performance Awards. Dividends and dividend equivalent rights are subject to the same performance goals as the underlying award and will not be paid until the performance award has vested and becomes earned. ✗ No Hedging or Derivative Transactions of Company Equity Securities. Occidental’s directors, executive officers and all other employees are not permitted to engage in transactions designed to hedge or offset the market value of Occidental’s equity securities. ✗ No Golden Parachute Payments. Our golden parachute policy provides that, subject to certain exceptions, Occidental will not grant golden parachute benefits (as defined in the policy) to any executive officer which exceed 2.99 times his or her salary plus ACI award without shareholder approval. ✗ No Repricing of Stock Options. Other than in connection with a corporate transaction involving Occidental, Occidental does not permit the repricing of stock options or stock appreciation rights without shareholder approval.

Compensation Discussion and Analysis

Participants in the Executive Compensation

Decision-Making Process

Chairperson AVEDICK B. POLADIAN WILLIAM R. KLESSE JACK B. MOORE KENNETH B. ROBINSON

Role of the Independent Compensation Committee

The Compensation Committee, composed entirely of independent members of the Board, is responsible for annually reviewing and

approving all aspects of the Chief Executive Officer’s compensation, as well as annually reviewing and approving the compensation of all

other NEOs. In performing these duties, the Compensation Committee obtains input, advice and information from senior management,

members of Occidental’s Human Resources (HR) team and an independent compensation consultant, as further described below,

throughout the year. The Compensation Committee also considers the views expressed by Occidental’s investors and shareholder

advisory groups in making executive compensation decisions. The Compensation Committee uses publicly available data regarding the

executive compensation practices of its compensation peer group (as defined below) as an additional tool but does not benchmark

executive compensation to a specific percentile within the peer group.

Role of Senior Management

Ms. Hollub, as Chief Executive Officer, makes recommendations to the Compensation Committee regarding the compensation package for

each of the other NEOs. Ms. Hollub and the Vice President of Human Resources are present for a portion of each Compensation

Committee meeting, but no senior executive is present when decisions regarding his or her compensation are discussed and determined.

Only the Compensation Committee sets Ms. Hollub’s compensation package. Senior members of the HR team and other members of

senior management interact with the compensation consultant as necessary and prepare materials for each Compensation Committee

meeting to assist the Compensation Committee in its consideration and administration of executive compensation programs, plans

and policies.

Role of the Independent Compensation Consultant

In 2025 , the Compensation Committee engaged Meridian Compensation Partners, LLC (Meridian) as its compensation consultant to

provide advice on various executive compensation matters. Meridian has served as the Compensation Committee’s compensation

consultant since 2016. The Compensation Committee reviewed the independence of Meridian under SEC rules, the NYSE Listed

Company Manual standards and Occidental’s Independent Compensation Consultant Policy and found Meridian to be independent and

without conflicts of interest. Occidental also participates in and reviews compensation surveys conducted by compensation consultants,

including Meridian, in order to better understand external compensation practices, including with respect to executive compensation.

Role of Shareholders

Occidental maintains an ongoing dialogue with its shareholders. Members of Occidental’s senior management team and, on a

case-by-case basis, one or more of Occidental’s independent directors, engage with shareholders through virtual and in-person meetings

and phone calls. Input from these meetings regarding Occidental’s executive compensation policies and practices is reviewed by the

Compensation Committee and considered when making future compensation decisions. For the 2025 compensation year, for example,

shareholder support for the pay-for-performance nature of Occidental’s executive compensation program informed the Compensation

Committee’s decision to continue the performance-based allocation of the LTI program at 60%. Shareholder feedback also contributed to

the Compensation Committee’s decisions to use free cash flow before working capital as a performance metric for the 2025 ACI award in

place of CROCE, disclose the threshold and maximum levels for the financial metrics and maintain the sustainability metric for such award.

Role of Peer Company Information

To evaluate how Occidental’s executive compensation program compares within the oil and gas industry, particularly with respect to award

types, compensation mix, performance metrics and reported levels of compensation, the Compensation Committee reviews the executive

compensation practices, programs and policies of a “compensation peer group,” as identified below. The Compensation Committee also

reviews and considers oil and gas industry compensation surveys and related materials. This information is used only as a reference and

not to establish compensation benchmarks, as the Compensation Committee does not benchmark executive compensation to a specific

percentile within the compensation peer group. Occidental also maintains a “performance peer group” within the oil and gas industry, and

the value of the TSR awards is dependent on Occidental’s three-year TSR performance as compared to the three-year TSR performance

of the companies within the applicable performance peer group. The Compensation Committee regularly reviews these peer groups to

assess whether they have reasonably similar business strategies, represent a mix of integrated and independent oil and gas companies

(including companies representative of different oil industry sectors such as upstream, downstream and integrated companies), are

comparable with Occidental in enterprise value and/or assets, and generally compete against Occidental for investor dollars and/or

executive talent.

Table of Contents

Compensation Discussion and Analysis

In 2024, the annual routine review prompted the Compensation Committee to revise the 2025 compensation peer group. The

Compensation Committee determined that it was appropriate to remove Pioneer Natural Resources Company and Hess Corporation

considering M&A activity involving each company and add The Williams Companies, Inc., Schlumberger Limited, Diamondback Energy,

Inc., Dow Inc., LyondellBasell Industries N.V. and Halliburton Company to broaden the industry sectors and balance the size of

companies represented.

In updating the 2025 compensation peer group, the Compensation Committee sought to address the persistent challenge of finding current

independent peers of comparable size in a shrinking pool of peer companies with the backdrop of dynamic market conditions within our

industries. Accordingly, the Compensation Committee expanded its review to include companies representative of different oil industry

sectors to include upstream, midstream, downstream, integrated, oilfield services and chemical companies and considered, among other

things, enterprise value and companies with which Occidental competes for talent. Consistent with its practice to not benchmark to a

specific percentile within the peer group, the Compensation Committee did not seek direct alignment with pay levels or practices at peer

companies when making the determination to update the 2025 compensation peer group. Going forward, the Compensation Committee

will continue to evaluate the composition of the compensation and performance peer groups given company changes (e.g., the OxyChem

divestiture), market conditions and other factors.

Elements of the 2025 Compensation Program

Salary

The Compensation Committee believes that base salary should reward executives on a market-competitive basis for consistent, superior

performance of job requirements and the achievement of short-term objectives. Salaries are evaluated by the Compensation Committee

annually and as circumstances warrant. In determining base salary levels, the Compensation Committee reviews compensation surveys,

publicly available peer company data, internal pay equity, individual responsibilities and performance assessments.

In connection with its annual review, the Compensation Committee approved increases in the base salaries for NEOs reflective of each

executive’s scope of responsibilities and prior year performance and to remain competitive in attracting and retaining top executive talent.

NEO — Vicki Hollub	$ 1,575,000	$ 1,600,000	1.6%
Sunil Mathew	$ 750,000	$ 810,000	8.0%
Richard A. Jackson (1)	$ 795,000	$ 925,000	16.4%
Kenneth Dillon	$ 795,000	$ 840,000	5.7%
Jeff F. Simmons	$ 720,000	$ 755,000	4.9%

(1) Effective February 12, 2025, Mr. Jackson’s base salary was increased by $45,000 to $840,000, representing a 5.7% increase. Then, effective on or about

October 1, 2025, Mr. Jackson’s base salary was increased by $85,000 to $925,000 in connection with his promotion to the position of Chief Operating Officer.

Base salary represented, on average, 12.5% of the 2025 compensation packages of the NEOs, based on compensation as reported in the

Summary Compensation Table on page 49 .

Annual Cash Incentive

The ACI award is intended to motivate executives to achieve superior company and individual performance over a one-year period. In the

first quarter of each plan year, the Compensation Committee approves individual target award amounts for each executive officer based on

a review of compensation surveys, publicly available peer company data, the executive’s prior-year award value, retention considerations,

the balance of short- and long-term pay and internal pay equity. The amounts earned by each NEO under the ACI award for 2025 , which

were paid in the first quarter of 2026 , are reflected in the “Non-Equity Incentive Plan Compensation” column of the Summary

Compensation Table on page 49 , as further described below.

Setting the ACI Award Target. In February 2025 , in connection with its annual review, the Compensation Committee approved slight

increases for the ACI award targets for Ms. Hollub and Messrs. Dillon and Jackson and moderate increases for the ACI award targets for

Messrs. Mathew and Simmons to align with market practices. All approved increases were also supported by strong 2024 performance.

Then, in October 2025 , the Compensation Committee, in consultation with Meridian, determined to further increase Mr. Jackson’s ACI

award target in connection with his promotion to Chief Operating Officer in light of publicly available peer company and other market data.

NEO — Vicki Hollub	$ 2,520,000	$ 2,560,000	1.6%
Sunil Mathew	$ 700,000	$ 810,000	15.7%
Richard A. Jackson (1)	$ 825,000	$ 925,000	12.1%
Kenneth Dillon	$ 825,000	$ 840,000	1.8%
Jeff F. Simmons	$ 700,000	$ 800,000	14.3%

(1) In February 2025, Mr. Jackson’s target ACI award opportunity was set at $840,000, an increase of $15,000 from 2024, representing a 1.8% increase. Then,

effective on or about October 1, 2025, Mr. Jackson’s target ACI award opportunity was increased by $85,000 to $925,000 in connection with his promotion to the

position of Chief Operating Officer.

Structure of the ACI Award. Potential payouts under the ACI award range from 0% to 200% of the target award amount, based on actual

company performance, and may be adjusted upward or downward by up to 25% based on individual NEO performance. No such individual

adjustments were made for 2025 .

Weighting the Metrics. The Compensation Committee annually reviews all facets of the ACI award, with an aim to incentivize the NEOs to

excel in areas that are aligned with Occidental’s business objectives. For the 2025 ACI award, the Compensation Committee approved

metrics related to the company’s total spend per barrel and free cash flow before working capital as well as strategy/innovation and

sustainability goals. The Compensation Committee set target performance goals for each metric that it believed were rigorous based on

Occidental’s detailed capital program and business plan, projections from the strategic planning team and business unit heads, prior-year

results and third-party forecasts relating to future market conditions and other external market factors.

Review and Final Determination. After determining the structure of the ACI award, at each regular meeting, Compensation Committee

members receive updates regarding and review progress toward each target performance goal and, following the performance period,

carefully analyze annual performance to inform the Compensation Committee’s payout determination.

2025 Annual Cash Incentive Award

2025 ACI Award Results. For the 2025 ACI awards, the award payout was determined by the company performance described in this

section. Although the 2025 ACI program permitted the increase or decrease of the ACI award payout by up to 25% based on individual

performance, the Compensation Committee did not make any such adjustments. Thus, for the 2025 ACI awards, all of the NEOs were paid

at 125% of target based on the company performance noted below.

(1) No pa youts are made in respect of a financial performance goal under the ACI award unless the applicable threshold performance level for such performance goal

is achieved.

(2) “Total Spend per Barrel” (TSPB) applies to continuing operations and equals the sum of SG&A, OPEX and CAPEX, divided by MMboe. For purposes of

the ACI award, “SG&A” or “selling, general and administrative expenses” means total SG&A and other operating and non-operating expenses for the company,

prior to any accrual for the 2025 ACI award; “OPEX” or “operating expenses” means total upstream oil and gas lease operating expenses; “CAPEX” or

“capital expenditures” means total capital investment for the company; and “MMboe” means total million “Boe,” or barrels of oil equivalent, produced in the year.

(3) Free Cash Flow before Working Capital is defined as cash flows from operations before changes in working capital less capital expenditures (net of contributions

from non-controlling interest).

(4) The Compensation Committee decided that the target metrics for technology/AI applications were met above target, with the rationale summarized below:

► Occidental progressed at least five advanced recovery methods through lab testing, modeling and/or field pilots across its U.S. Onshore assets in 2025.

These methods improved well performance and recovery by reenergizing the reservoir, reducing interfacial tension and/or altering the wettability of the

formation. Demonstration projects executed in 2025 spanned multiple fields across the Permian and DJ Basins with additional methods pending execution

at year-end.

► Occidental deployed multiple completions technologies to improve well performance and cost efficiency. These technologies are designed to enable

improvements through more efficient operations and enhanced data collection. Technologies allow for multiple wells completions at once, continuous pumping,

automated completions or enhanced data collection through various vendor products. These technologies were utilized across five frac cores and multiple

fields within the Permian Basin throughout 2025.

► Occidental continued efforts to strengthen its portfolio of execution-ready Unconventional EOR projects by completing development plans for multi-year

injection projects. Additionally, Occidental created the EOR Ventures organization to accelerate the development and deployment of this long-term

growth opportunity.

► In 2025, Occidental developed 20 AI projects that each range from $10-$90 million in estimated annual benefit. At year-end, 14 of these projects had been

deployed, four were in the piloting phase, and two remained under development.

► In 2025, Occidental developed several new AI tools for reservoir characterization that improve our subsurface understanding. These tools have been

incorporated into traditional geoscience platforms for business application. Blind testing of results has confirmed that predictive results are improved.

(5) The Compensation Committee also determined that the target metrics for low carbon ventures were met at target, with the rationale summarized below:

► In 2025, Occidental commissioned the STRATOS wet loop and added chemical to commence CO 2 capture. It also progressed central processing and calciner

commissioning with an initial calciner burner testing.

► Occidental achieved pilot-scale success in multiple next-generation technologies designed to reduce the equipment, materials and energy required for CE’s

DAC technology, proceeding with incorporation into the CE Innovation Center demonstration plant. Such advancements are expected to enable operational

footprint and cost reductions.

► Occidental obtained Class VI sequestration permits and authorization to inject from the U.S. EPA in 2025 for the Brown Pelican sequestration facility

associated with STRATOS.

(6) The Compensation Committee also determined that the target metrics for emission reduction projects were met at target, with the rationale summarized below:

► Occidental implemented more than 10 emissions reduction projects in 2025 involving hundreds of facilities and wells and thousands of pieces of equipment

across our oil and gas operations, including facility consolidations to remove compressors, tanks and other equipment; upgrades of vapor recovery systems;

implementation of compressor emission controls; additional fuel gas metering; continuing removal or conversion of gas-driven pneumatic devices; ongoing

field and equipment electrification; and expansion of takeaway capacity in Oman to reduce flaring.

► Occidental entered into three power purchase agreements for renewable energy in Texas; installed solar canopies at parking lots in Oman’s residential camps;

and continued to advance low-carbon technologies with partners, including demonstration projects using TerraLithium’s patented direct lithium extraction

process from geothermal brine.

► Occidental implemented multiple complementary methane detection technologies in 2025, including voluntary leak detection and repair surveys, flare

destruction and removal efficiency testing, and an increased frequency and coverage of aerial methane surveys using aircraft or drones to further accelerate

and validate our Find It/Fix It program.

Long-Term Incentive Program

The majority of NEO compensation is determined by Occidental’s long-term performance. The LTI awards are intended to motivate and

incentivize executives to achieve results (including stock price performance) that are consistent with Occidental’s strategic business

objectives. The Compensation Committee believes that long-term incentive compensation should represent the largest portion of each

NEO’s total compensation package and that the levels of payout ultimately achieved should reflect Occidental’s performance, both relative

to peer company performance and on an absolute basis. During the process of determining the NEOs’ LTI compensation packages for

2025 , the Compensation Committee evaluated many factors, including:

► Alignment of executive officer pay to achieving long-term growth in shareholder value;

► Linkage of any above-target payouts to superior performance and absolute returns;

► Shareholder feedback regarding long-term compensation metrics;

► Competitiveness with the compensation programs of peer companies;

► Impact of commodity prices on Occidental’s stock price and financial performance; and

► Allocation of total compensation between long-term and short-term components.

Table of Contents

Compensation Discussion and Analysis

2025 Long-Term Incentive Program. The 2025 LTI program consisted of two PSU awards (one based on Occidental’s relative and

absolute TSR and the other based on absolute CROCE performance) and a time-based RSU award as follows:

30%

CROCE Award

40%

RSU Award

30%

TSR Award

Forfeiture and change in control provisions applicable to the awards are discussed in more detail in the Potential Payments upon

Termination or Change in Control table and the accompanying footnotes beginning on page 56 .

Setting the LTI Award Target. In February 2025 , in connection with its annual review, the Compensation Committee approved modest

increases for the LTI award targets for NEOs.

NEO — Vicki Hollub	$ 11,800,000	$ 12,250,000	3.8%
Sunil Mathew	$ 3,200,000	$ 3,300,000	3.1%
Richard A. Jackson (1)	$ 3,600,000	$ 3,700,000	2.8%
Kenneth Dillon	$ 3,600,000	$ 3,700,000	2.8%
Jeff F. Simmons	$ 3,100,000	$ 3,200,000	3.2%

(1) Excludes the one-time grant of RSUs valued at $1,500,000 in connection with Mr. Jackson’s promotion to the position of Chief Operating Officer, which is

discussed in more detail below.

Total Shareholder Return (TSR) Award. The Compensation Committee believes that the comparison of Occidental’s three-year TSR to

peer companies’ TSR over the same period is an objective external measure of Occidental’s effectiveness in translating its results into

shareholder returns. TSR is the change in price of a share of common stock plus reinvested dividends, over a specified period of time, and

is an indicator of management’s achievement of long-term growth in shareholder value. Payout of the TSR award is based on Occidental’s

three-year TSR as compared to the three-year TSR of the performance peers identified on page 40 . The TSR award is denominated in

PSUs, each of which is equivalent to one share of common stock. The percentage of target PSUs that will be payable at the end of the

three-year performance period, which began January 1, 2025 and ends December 31, 2027 , will depend on Occidental’s relative and

absolute TSR performance.

If Occidental’s absolute TSR is negative over the performance period, then, irrespective of Occidental’s ranking within the peer group, the

payout of the TSR award is capped at no more than target. A table illustrating the potential payout of the TSR award based on relative and

absolute TSR performance is set forth below:

TSR Ranking	% of Target PSUs Earned
#1	200%
#2	180%
Between #2 and #8	Linearly interpolated between 25% and 180%
#8	25%
#9	0%
For payout above 100%, Occidental’s absolute TSR must be positive.

Compensation Discussion and Analysis

An example of the interpolation calculation if Occidental ranked fourth among its TSR performance peers with respect to the 2025 TSR

awards is as follows:

TSR Ranking	Formula Points	Company	Standing	% of Target PSUs Earned
#1		AAA	22.50%	200%
#2	B	BBB	20.00%	180%
#3		CCC	17.50%	Linearly interpolated between 25% and 180%
#4		OXY	15.00%
#5		DDD	12.50%
#6		EEE	10.00%
#7		FFF	7.50%
#8	A	GGG	5.00%	25%
#9		HHH	2.50%	0%
Interpolation Formula = 25% + [(180% - 25%) x ((OXY TSRI – A) / (B – A))] Interpolation Formula = 25% + [155% x ((15% - 5%) / (20% - 5%))]
Example Interpolation Payout Result = 128.3%

The cap on the TSR award payout if absolute TSR performance over the performance period is negative is intended to reinforce the

pay-for-performance nature of the compensation program. Cumulative dividend equivalents will be paid in cash at the end of the

three-year performance period and will be paid only on the number of PSUs earned.

No Payout of 2023 TSR Awards. No amounts were earned under the 2023 TSR awards, which had a performance period that ended on

December 31, 2025 and were structured similarly to the 2025 TSR awards described above.

Cash Return on Capital Employed (CROCE) Award . The CROCE award is designed to focus executives on the efficient use of capital

by promoting discipline in capital allocation decisions. CROCE is a transparent measure of how efficiently Occidental uses its capital and is

calculated from Occidental’s audited financial statements with no adjustments for special items. The Compensation Committee aims to set

the CROCE performance targets at a challenging level for each performance period based on our capital program, multi-year business

plan and strategy, projections from our strategic planning teams, historical results and third-party forecasts relating to future market

conditions. The CROCE award is denominated in PSUs, each of which is equivalent to one share of common stock. The percentage of

target PSUs that become payable at the end of the applicable three-year performance period depends on Occidental’s absolute CROCE

during the performance period. A table illustrating the potential payout of the 2025 CROCE award based on three-year CROCE

performance is set forth below:

CROCE Performance Targets (1)	% of Target PSUs Earned (2)
CROCE of ≥ 21%	200%
CROCE of 19%	100%
CROCE of 17%	25%
CROCE < 17%	0%

(1) See page 73 for the formula to calculate CROCE.

(2) Payout percentages for CROCE values between 17% and 21% to be determined using linear interpolation between 25% and 200% of target, with a target payout at

a CROCE of 19%.

Our CROCE performance targets were set at a slightly lower level for the 2025 CROCE award compared to the 2024 CROCE award to

reflect operating and financial plans that incorporated expectations, based on both internal and third-party projections and analyses, for a

less favorable commodity price environment over the three-year performance period of the 2025 CROCE award as compared to the prior

performance period; considering these factors, the Compensation Committee believes that the 2025 CROCE award performance targets

were set at a rigorous level for value creation and were at least as challenging as those for the 2024 CROCE award.

Payout of 2023 CROCE Awards. For the 2023 CROCE award, which had a performance period that ended on December 31, 2025 ,

Occidental achieved a three-year CROCE of approximately 21.1% as of the end of the performance period, which exceeded the target

performance level of such CROCE award. Thus, the Compensation Committee approved a payout result of 104.6%.

Restricted Stock Unit (RSU) Award. The 2025 RSU award vests ratably over three years with one-third vesting on each of February 28,

2026 , 2027 and 2028 , subject to continued employment.

In addition, in connection with Mr. Jackson’s promotion to the position of Chief Operating Officer during October 2025, the Compensation

Committee approved a one-time RSU award to Mr. Jackson valued at $1,500,000 following consultation with Meridian and review of

pertinent information, including market compensation data, to align with market practices and increase his alignment with shareholders.

The RSU award vests in equal annual installments over a three-year period subject to Mr. Jackson’s continued service through the

applicable vesting dates.

Each RSU is equivalent to one share of common stock, and payment for a vested RSU award will be made solely in shares of common

stock. The shares of stock ultimately received by the NEO pursuant to the RSU award are subject to a two-year post-vesting holding

period. Dividend equivalents are accrued and paid out upon vesting.

Other Compensation and Benefits

Qualified Defined Contribution Plans

Occidental does not have a defined benefit pension plan that provides NEOs a fixed monthly retirement payment. Instead, all salaried

employees on the U.S. payroll, including the NEOs, are eligible to participate in one or more tax-qualified defined contribution plans.

Savings Plan . For 2025 , the defined contribution 401(k) savings plan (Savings Plan) permitted employees to save a percentage of their

eligible annual salary, which was up to $350,000 (the limit set by IRS regulations), and employee pre-tax contributions were limited to

$23,500. Employees may direct their contributions to a variety of investments. Occidental matches two dollars for every one dollar the

employee contributes up to 2% of eligible pay, plus an additional dollar-for-dollar match on the next 3% of eligible pay. The NEOs are fully

vested in their account balances under the Savings Plan. The amounts contributed by Occidental to the Savings Plan are included in the

“All Other Compensation” column of the Summary Compensation Table on page 49 .

Retirement Plan. The defined contribution retirement plan (Retirement Plan) is funded annually through a reallocation process from the

employee’s Supplemental Retirement Plan II (SRP II) account balance (described below). Because the exact amount that could be

contributed to the Retirement Plan without exceeding governmental limits cannot be determined until the end of the year, the reallocation

process has been developed to maximize the amount contributed each year to a tax-qualified defined contribution plan. The Retirement

Plan is company-funded, and employees may not contribute to the Retirement Plan. The NEOs are fully vested in their account balances

under the Retirement Plan. The amounts allocated to the Retirement Plan are included in the SRP II contributions by Occidental in the

“All Other Compensation” column of the Summary Compensation Table on page 49 .

Nonqualified Deferred Compensation Plans

Occidental maintains two nonqualified deferred compensation plans: (i) the SRP II and (ii) the Modified Deferred Compensation Plan

(MDCP). The purpose of the SRP II is to provide eligible employees, including the NEOs, with benefits to compensate them for maximum

limits imposed by law on the amount of contributions that may be made to Occidental’s tax-qualified defined contribution plans.

The purpose of the MDCP is to provide key management and highly compensated employees the ability to accumulate additional

retirement income through deferrals of compensation.

Additional information regarding the terms and conditions of the SRP II and the MDCP is provided in “Nonqualified Deferred

Compensation” on pages 53 and 54 . Amounts contributed to the SRP II on behalf of the NEOs are included in the “All Other

Compensation” column of the Summary Compensation Table on page 49 and above market earnings under the plans are included in the

“Nonqualified Deferred Compensation Earnings” column of the Summary Compensation Table on page 49 . None of the executive officers

made contributions to the MDCP or SRP II in 2025 . The contributions, aggregate earnings, withdrawals and aggregate balances for the

NEOs in the SRP II and MDCP with respect to 2025 are shown in the Nonqualified Deferred Compensation table on page 54 .

Retirement Policy

Each of Occidental’s NEOs and certain other key employees are eligible participants under the Occidental Petroleum Corporation

Retirement Policy. See “Executive Severance and Change in Control—Retirement Policy” on page 55 for a description of the policy.

Other Personal Benefits

Occidental provides a limited number of other personal benefits for its NEOs, which, in 2025 , consisted principally of fees related to excess

liability insurance and financial counseling which are included in the “All Other Compensation” column of the Summary Compensation

Table on page 49 .

Additional Compensation Policies and Practices

Stock Ownership Guidelines

Occidental’s stock ownership guidelines are intended to more closely align the interests of the NEOs and other officers with those of the

company’s shareholders. The ownership guidelines range from two to six times the officer’s annual base salary, based on position, as

illustrated below :

Position	Multiple of Base Salary
Chief Executive Officer	6
Chief Financial Officer	4
Chief Operating Officer	4
Senior Vice Presidents	3
Vice Presidents	2

An officer who does not meet the minimum ownership guidelines may not sell any shares of Occidental common stock until he or

she meets the ownership guidelines and would continue to meet the ownership guidelines following any such sale. Unvested

performance-based stock awards, unvested PSUs and unexercised stock options do not count toward satisfaction of the stock ownership

guidelines. Officers subject to the guidelines are expected to comply within five years of the date the individual is first elected to the office.

As of March 1, 2026 , each of the NEOs was in compliance with these guidelines.

Equity Grant Practices

The Compensation Committee generally approves annual equity awards each year at its regularly scheduled Compensation Committee

meeting in February. Consistent with such practice, at its regularly scheduled February 2025 meeting, the Compensation Committee

approved 2025 equity grants pursuant to the LTI program with a grant date of March 1, 2025 . The grant date fair value of each of the

CROCE and RSU awards was based on the closing price of Occidental’s common stock on the NYSE on the grant date, and the grant

date fair value of the TSR award also incorporates the estimated payout percentage of the award as of the grant date. Awards may also be

granted throughout the year, generally in instances of new hires, promotions or other special occasions. In addition, as specifically

authorized by the terms of the LTIP, Ms. Hollub and our Vice President, Human Resources have been delegated the authority to grant

equity awards in certain circumstances to new employees and to grant equity awards to Occidental’s employees who are not executive

officers, in each case, within specified limits.

During 2025 , the Compensation Committee did not take into account any material non-public information when determining the timing and

terms of equity incentive awards, and Occidental did not time the disclosure of material non-public information for the purpose of affecting

the value of executive compensation. During 2025 , Occidental also did not grant any equity awards to any of the NEOs other than at its

regularly scheduled February 2025 meeting, except for the RSU award granted in October 2025 to Mr. Jackson in connection with his

promotion to the position of Chief Operating Officer. Occidental did not grant any stock options or stock appreciation rights to the NEOs at

any time in 2025 . Occidental may change its equity grant practices in the future.

Potential Recoupment of Compensation Due to Misconduct

Occidental maintains the Occidental Petroleum Corporation Clawback Policy, which is intended to comply with the requirements of NYSE

Listing Standard 303A.14 implementing Rule 10D-1 under the Securities Exchange Act. In the event Occidental is required to prepare an

accounting restatement of Occidental’s financial statements due to material non-compliance with any financial reporting requirement under

the federal securities laws, Occidental will recover the excess incentive-based compensation received by any covered executive officer,

including the NEOs, during the prior three fiscal years that exceeds the amount that the executive officer otherwise would have received

had the incentive-based compensation been determined based on the restated financial statements.

In addition, Occidental may recoup certain compensation (including both time- and performance-based LTI awards) from executive officers

in the event of misconduct pursuant to the terms of Occidental’s Code of Business Conduct, the ACI awards and the LTIP. Occidental’s

Code of Business Conduct prohibits any officer, employee or director from violating or circumventing any law of the United States or a

foreign country or engaging in unethical conduct during the course of his or her employment. The Audit Committee oversees compliance

with the Code of Business Conduct and has implemented procedures, including a compliance helpline, to encourage prompt reporting of

violations or suspected violations of the Code of Business Conduct, without fear of retaliation. In general, misconduct may have several

consequences, including:

► Disciplinary action, which may include termination, referral for criminal prosecution and reimbursement to Occidental or others for any

losses or damages resulting from the violation;

► Forfeiture of stock awards, in whole or in part, in the case of an employee’s termination for cause; and

► Forfeiture or reduction of the ACI award for violations of the Code of Business Conduct or related policies.

In addition, the LTIP includes a provision that gives Occidental the contractual right to recoup awards where a participant has breached

Occidental’s Code of Business Conduct by violating applicable law or company policy or engaging in unethical conduct.

Compensation Discussion and Analysis

Risk Assessment of Compensation Policies

and Practices

Although the majority of the executive compensation program is performance-based, the Compensation Committee believes Occidental’s

compensation programs do not encourage unnecessary or excessive risk-taking. In reaching its conclusion, the Compensation Committee

reviewed the findings of a risk-taking analysis performed by its independent compensation consultant, Meridian. The Compensation

Committee concurred with Meridian’s finding that Occidental’s compensation programs include multiple features that appropriately mitigate

excessive risk-taking and that the compensation programs do not encourage excessive risk-taking. With respect to the executive

compensation program, the compensation features that are indicative of appropriate risk-taking include:

► Diversified Performance Metrics. The ACI award and LTI awards consider multiple performance criteria, rather than a single metric.

► Balanced Pay Mix. The total compensation opportunity features an effective balance between short- and long-term

compensation components.

► Capped Awards. Performance-based stock awards and the ACI award are capped as a percentage of the targeted award and payout

of the TSR award is capped at target if Occidental’s absolute TSR is negative over the performance period.

► Stock Ownership Guidelines and Holding Periods. Meaningful stock ownership guidelines and holding requirements for executives

encourage a long-term perspective and require holding stock for extended periods.

► Clawback Provisions. The ACI award and LTI awards are subject to clawback provisions beyond legal requirements, including

forfeiture and recoupment provisions of awards in the event of violations of Occidental’s Code of Business Conduct.

► Anti-Hedging Provisions. Occidental’s executive officers, directors and other employees are prohibited from purchasing financial

instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) or otherwise engaging in

transactions that are designed to, or have the effect of, hedging or offsetting any decrease in the market value of

Occidental’s securities.

► Insider Trading Policy. Occidental has adopted an insider trading policy (the Insider Trading Policy) governing the purchase, sale,

and/or other dispositions of its securities by its directors, officers, employees, contractors and certain entities. Occidental believes that

the Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations and the listing

standards applicable to the company. A copy of the Insider Trading Policy was filed as Exhibit 19.1 to our Annual Report on Form 10-K

for the fiscal year ended December 31, 2024.

Compensation Committee Report

The Compensation Committee has reviewed and discussed with management the preceding Compensation Discussion and Analysis

section for the year ended December 31, 2025 . Based on these reviews and discussions, the Compensation Committee recommended to

the Board of Directors that the Compensation Discussion and Analysis be included in the proxy statement for the 2026 Annual Meeting

of Shareholders.

(1) For 2025 , amounts shown represent the aggregate grant date fair value of the CROCE, RSU and TSR long-term incentive awards granted to the NEOs, as

applicable. The grant date fair value of each of the CROCE and RSU awards equals the target number of stock units granted multiplied by Occidental’s

closing stock price on the grant date (or the last trading day prior to the grant date). The grant date fair value of the TSR award is calculated based on a

Monte-Carlo valuation on the date of grant, determined under Financial Accounting Standards Board Accounting Standard Codification Topic 718 (FASB

ASC 718). See Note 14 to the Consolidated Financial Statements in Occidental’s Annual Report on Form 10-K regarding assumptions underlying the

valuation of the TSR award. The maximum values of the 2025 TSR awards as of the grant date for Ms. Hollub, Mr. Mathew, Mr. Jackson, Mr. Dillon, and

Mr. Simmons were approximately $7.4 million, $2 million, $2.2 million, $2.2 million, and $1.9 million, respectively. The maximum values of the 2025 CROCE

awards as of the grant date for Ms. Hollub, Mr. Mathew, Mr. Jackson, Mr. Dillon, and Mr. Simmons were approximately $7.4 million, $2 million, $2.2 million,

$2.2 million and $1.9 million, respectively. The RSU awards have no above-target payout scenario. For more information, see “Compensation Discussion

(1) Amounts shown reflect the possible payout range of the 2025 ACI award. For the actual amounts earned pursuant to the ACI award, see the “Non-Equity Incentive

Plan Compensation” column of the Summary Compensation Table on page 49 . For 2025 , payout of the ACI award was based on Occidental’s performance with

respect to certain key company performance metrics. The ACI award is described further under “Compensation Discussion and Analysis — Elements of the 2025

Compensation Program — Annual Cash Incentive” beginning on page 41 .

(2) The grant date fair value of the CROCE award is equal to the target number of CROCE PSUs originally granted multiplied by $48.84, the closing price of

Occidental’s common stock on February 28, 2025, the last trading day prior to the grant date. Actual payout of the CROCE award may be zero or range from

25% to 200% of the target number of CROCE PSUs granted based on Occidental’s CROCE at the end of the three-year performance period. For more

information regarding the payout possibilities of the CROCE award, see “Compensation Discussion and Analysis—Elements of the 2025 Compensation

Program — Long-Term Incentive Program — Cash Return on Capital Employed (CROCE) Award” on page 45 .

(3) The grant date fair value of the RSU award is equal to the number of RSUs granted multiplied by $48.84, the closing price of Occidental’s common stock on

February 28, 2025, the last trading day prior to the grant date. The RSU award vests ratably over three years with one-third vesting on each of February 28, 2026 ,

2027 and 2028 , subject to continued employment, and is payable in shares of common stock upon vesting. The vested shares are subject to a two-year holding

period. The value of the RSU award at vesting will depend on the closing price of Occidental’s common stock on each vesting date. For more information regarding

the RSU award, see “Compensation Discussion and Analysis — Elements of the 2025 Compensation Program — Long-Term Incentive Program — Restricted Stock

Unit (RSU) Award” on page 45 .

(4) The grant date fair value of the TSR award is based on a Monte Carlo simulation in accordance with FASB ASC 718. Actual payout of the TSR award may be zero

or range from 25% to 200% of the target number of TSR PSUs granted based on Occidental’s TSR at the end of the three-year performance period as compared to

the TSR of the performance peer companies, and whether Occidental’s absolute TSR value for the performance period is positive. For more information regarding

the payout possibilities of the TSR award, see “Compensation Discussion and Analysis — Elements of the 2025 Compensation Program — Long-Term Incentive

Program—Total Shareholder Return (TSR) Award” beginning on page 44 .

(5) Amounts shown reflect the RSU award granted to Mr. Jackson in connection with his promotion to Chief Operating Officer. The grant date fair value of this RSU

award is equal to the number of RSUs granted multiplied by $47.72, the closing price of Occidental’s common stock on the grant date. The RSU award vests ratably

over three years with one-third vesting on each of September 30, 2026, 2027 and 2028.

(1) Anti-dilution adjustments were previously made to the exercise price and the number of shares of common stock underlying the 2020 nonqualified stock option

(NQSO) and stock appreciation right (SAR) awards in connection with the warrant distribution on August 3, 2020. The closing price of Occidental’s common stock

on the NYSE on December 31, 2025 ( $41.12 ) was in excess of the strike price of the outstanding 2020 and 2021 NQSO awards and the grant price of the 2020

SAR award.

Occidental’s common stock on the NYSE on December 31, 2025 .

(3) The RSU awards vest ratably over a three-year period, subject to continued employment. The unvested portion of the RSU award granted in February 2023 vested

on February 28, 2026; one-third of the total RSU award granted in March 2024 vested on February 28, 2026 and the remaining unvested portion will vest on

Occidental’s performance through December 31, 2025 , the 2024 and 2025 CROCE awards were trending below threshold performance, which would result in zero

payout. The CROCE awards vest based on the achievement of the applicable CROCE performance goal over the three-year performance period. The performance

periods for the 2024 and 2025 CROCE awards end on December 31, 2026 and December 31, 2027, respectively. The ultimate payout may be less than the

Occidental’s performance through December 31, 2025 , the 2024 TSR awards were trending below threshold performance, which would result in zero payout.

The TSR awards vest based on the achievement of the applicable TSR performance goal over the three-year performance period. The performance periods for the

2024 and 2025 TSR awards end on December 31, 2026 and December 31, 2027, respectively. The ultimate payout may be less or more than the amounts shown,

Stock Vested in 2025

The following table summarizes, for the NEOs, the stock awards vested during 2025 . No NQSO or SAR awards were exercised by the

NEOs in 2025 .

PREVIOUSLY GRANTED STOCK AWARDS VESTED IN 2025

Name	Stock Awards — Number of Shares Acquired on Vesting (#)	Value Realized on Vesting ($) (1)
V. Hollub	128,789	$ 6,187,775

K. Dillon	40,818	$ 1,961,731
J. Simmons	26,744	$ 1,306,177

(1) Amounts shown represent the product of the number of shares vested and the closing price of Occidental’s common stock on the NYSE on either the award’s

certification date, for performance-based awards, or the award’s vesting date, for time-vested awards. In each case, the number of shares acquired at vesting and

the value realized at vesting do not include any reduction in vested shares or value realized associated with the withholding of shares to satisfy tax

withholding obligations.

Nonqualified Deferred Compensation

Supplemental Retirement Plan II

Employees whose participation in Occidental’s tax-qualified defined contribution plans is limited by applicable tax laws are eligible to

participate in Occidental’s SRP II, which provides additional retirement benefits outside of those limitations.

Annual plan allocations for each participant restore the amounts that would have accrued for salary, ACI award amounts and bonus

amounts, if any, under the qualified plans, but for the tax law limitations. Account balances are fully vested after three years of service and

are payable following a separation from service, or upon the attainment of a specified age, as elected by the participant. Each of the NEOs

is fully vested in his or her aggregate balance shown on page 54 .

Interest on SRP II accounts is allocated daily to each participant’s account. The amount of interest earnings is calculated using a rate

equal to the five-year U.S. Treasury Note rate on the last business day of the preceding month plus 2%, on a daily basis with

monthly compounding.

Modified Deferred Compensation Plan

Under the MDCP, the maximum amount of an executive officer’s salary or ACI award payment that may be deferred for any one year is

limited to $150,000. A participant’s overall plan balance must be less than $2 million at the end of any given year to enable a participant to

defer compensation for the subsequent year. Interest on MDCP accounts is allocated daily to each participant’s account. The amount of

interest earnings is calculated using a rate equal to the five-year U.S. Treasury Note rate on the last business day of the preceding month

plus 2%, on a daily basis with monthly compounding.

The following table sets forth the 2025 contributions, earnings, withdrawals and balances under the SRP II and the MDCP, to the extent the

NEOs participated in such plans. The footnotes provide information about other amounts that were previously reported as compensation in

the Summary Compensation Table on page 49 for 2025 and prior years.

Ms. Hollub – $485,709 ; Mr. Mathew – $102,462 ; Mr. Jackson – $198,344 ; Mr. Dillon – $280,678 and Mr. Simmons – $125,733.

Executive Severance and Change in Control

Occidental adopted the Severance Plan and the CIC Severance Plan (each as defined below) to allow Occidental’s executives to continue

to exercise their judgment and perform their responsibilities without the potential for distraction that can arise from concerns regarding their

personal circumstances. In reviewing each plan, the Compensation Committee consulted with its independent compensation consultant,

Meridian, to develop market-based severance benefits that are competitive within the oil and gas industry and that reflect broader

U.S. industry practices.

Receipt of any severance benefits is subject to the executive’s execution of a release of any claims against Occidental, as well as

compliance with any restrictive covenants that the Compensation Committee determines in its discretion.

Executive Severance Plan

Occidental maintains the Occidental Petroleum Corporation Executive Severance Plan (the Severance Plan), which is applicable to

Occidental’s executive officers. The Severance Plan provides severance benefits in the event that an eligible executive’s employment with

Occidental and its subsidiaries is terminated other than for “cause” (as defined in the Severance Plan). The Severance Plan does not

provide benefits upon a resignation by an executive for any reason. The severance benefits provided under the Severance Plan are

as follows:

► Cash Severance. Cash severance equal to 1.5 times (or, in the case of Occidental’s Chief Executive Officer, 2.0 times) the sum

of (A) the executive’s base salary in effect on the termination date and (B) the executive’s target annual bonus.

► Pro-Rata Bonus. The pro-rata portion of the executive’s target annual bonus for the year of termination.

► Welfare Benefits. Continued participation of the executive (and eligible dependents) in the basic life, medical and dental plans in

which the executive participated immediately before the termination date at the same rates and levels that the executive participated

prior to termination, in accordance with the terms of such plans, for two years following the termination date.

► Accelerated or Continued Vesting of Long-Term Incentive Awards. The service-based vesting condition applicable to any

long-term incentive award would be deemed to be met with respect to a pro-rata portion of the award. If the award is also subject to

performance-based vesting conditions, the pro-rata portion of such award would continue to be subject to the satisfaction of the

applicable performance conditions. Any individual performance goals that are not based on objective financial performance criteria

would be deemed earned at target performance.

► Outplacement. Outplacement services for up to nine months following the termination date.

The Severance Plan also includes a “net best after tax provision” such that if any of the executive’s payments under the Severance Plan or

otherwise would be subject to “golden parachute” excise taxes under the Internal Revenue Code, the payments to the executive will be

reduced in order to limit or avoid the “golden parachute” excise tax if and to the extent such reduction would produce an expected better

after-tax result for the executive.

Executive Compensation Tables

Change in Control Severance Plan

Occidental also maintains the Occidental Petroleum Corporation Executive Change in Control Severance Plan (the CIC Severance Plan),

which provides enhanced severance benefits to Occidental’s executive officers upon qualifying terminations of employment within two

years following a Change in Control (as defined in the CIC Severance Plan).

The CIC Severance Plan complements Occidental’s Executive Severance Plan, which provides severance benefits upon qualifying

terminations before a Change in Control and after the two-year protection period following the Change in Control but does not provide for

enhanced change in control termination protections.

Severance benefits are payable under the CIC Severance Plan if an eligible executive’s employment with Occidental and its subsidiaries is

terminated within two years following a Change in Control either (A) by Occidental (other than for “cause” (as defined in the CIC Severance

Plan)) or (B) by the executive for “good reason” (as defined in the CIC Severance Plan). The severance benefits provided under the CIC

Severance Plan are as follows:

► Cash Severance. Cash severance equal to 2.00 times (or, in the case of Occidental’s Chief Executive Officer, 2.99 times) the sum of

(A) the executive’s base salary (based on the highest base salary in effect at any time during the three-year period preceding the

Change in Control or at any time on or after the Change in Control) and (B) the executive’s target annual bonus.

► Pro-Rata Bonus. The pro-rata portion of the executive’s annual bonus for the year of termination, determined based on the greater of

(A) the executive’s target annual bonus and (B) the amount of such bonus that would have been due for the full year based on actual

results for such year, had the executive remained employed through the payment date.

► Welfare Benefits. Continued participation of the executive (and eligible dependents) in the basic life, medical and dental plans in

which the executive participated immediately before the termination date at the same rates and levels that the executive participated

prior to termination, in accordance with the terms of such plans, for two years following the termination date.

► Accelerated Vesting of Long-Term Incentive Awards. Vesting of all outstanding long-term incentive awards with performance-based

awards vesting at the greater of target performance and actual performance, except that any individual performance goals that are not

based on objective financial performance criteria would be deemed earned at target performance.

► Outplacement. Outplacement services for up to nine months following the termination date.

Like the Severance Plan, the CIC Severance Plan also includes a “net best after tax provision.”

Retirement Policy

Each of Occidental’s NEOs and certain other key employees are eligible participants under the Occidental Petroleum Corporation

Retirement Policy (the Retirement Policy).

The Retirement Policy establishes general guidelines and principles with respect to the retirement of eligible executives and is designed to

support Occidental’s succession planning and talent development strategy. Under the Retirement Policy, executives are expected to help in

the transition of their roles and in exchange for such assistance will be eligible to receive the following benefits in the event of an Eligible

Retirement (as defined below), subject to the executive’s execution of a separation agreement (which will include a release of claims and

may include confidentiality, non-competition and non-solicitation covenants):

► Accelerated Vesting of Long-Term Incentive Awards. Accelerated vesting of outstanding long-term incentive awards, with any

performance-based awards subject to actual performance; and

► Pro-Rata Bonus. A pro-rated annual bonus for the year in which such E ligible Retirement occurs (pro-rated based on the number of

days employed during the performance period), subject to actual performance.

An “Eligible Retirement” under the Retirement Policy means the executive’s retirement in accordance with Occidental’s general succession

planning efforts after (i) reaching at least 60 years of age and (ii) completing at least 10 years of eligible service (or five years of service

directly with Occidental if the executive became an Occidental employee due to Occidental’s purchase of another business), so long as

such executive (A) provides six months written notice of his or her intent to retire, (B) cooperates with the transition of such executive’s

role, and (C) complies with any applicable restrictive covenants.

As of December 31, 2025 , Ms. Hollub, Mr. Dillon, and Mr. Simmons were the only NEOs who could qualify for an Eligible Retirement based

on their age and years of eligible service with Occidental.

Executive Compensation Tables

Potential Payments upon Termination or Change

in Control

Payments and other benefits provided to NEOs in various termination circumstances or in connection with a change in control are subject

to certain policies, plans and agreements. The material terms of these arrangements are summarized above and below. Except as

described in this CD&A, Occidental does not have any other agreements or plans that will require compensation to be paid to NEOs in the

event of a termination of employment or a change in control.

Golden Parachute Policy. Occidental’s Golden Parachute Policy provides that, subject to certain exceptions, Occidental will not grant

Golden Parachute Benefits (as defined in the policy) to any senior executive that exceed 2.99 times his or her salary plus ACI pay, unless

the grant of such benefits is approved by a vote of Occidental’s shareholders. The complete Golden Parachute Policy is available at

www.oxy.com.

Outstanding Equity Awards. All outstanding awards held by our NEOs are subject to double-trigger vesting upon a “change in

control” (as defined in the LTIP). Payout under each of the outstanding equity awards in the event of various termination circumstances or

in connection with a termination following a change in control are described in more detail in the footnotes to the Potential Payments table

on page 56 .

Potential Payments

In the table that follows, payments and other benefits provided to the NEOs in connection with various termination and termination

following a change in control situations are set out as if the conditions for payment had occurred and the applicable triggering events took

place on December 31, 2025 , with equity values calculated using the closing price of Occidental’s common stock as of December 31, 2025

( $41.12 ), the last trading day of our 2025 fiscal year. The amounts shown are in addition to the payments and benefits that are potentially

available to all full-time salaried U.S. payroll employees, such as amounts vested under the Savings Plan and other tax-qualified retirement

plans, amounts vested under Occidental’s nonqualified deferred compensation plans, payment for accrued PTO up to a maximum accrual

ceiling of 350 hours, and disability benefits, among others.

Actual amounts to be paid will depend on several factors, such as the date of each NEO’s separation from Occidental or the occurrence of

a change in control event, Occidental’s ultimate achievement of performance goals underlying performance awards and the price of

Occidental’s common stock when such awards are earned, if at all. The disclosures below do not take into consideration any requirements

under Section 409A of the Internal Revenue Code, which could affect the timing of payments and distributions, or any reductions resulting

from the application of the net best after tax provisions under the Severance Plan and CIC Severance Plan.

(1) The treatment of outstanding equity awards in connection with each termination scenario specified in this table is summarized in the chart below:

Type of Award	Eligible Retirement under the Retirement Policy	Retirement with Occidental Consent (which is not an Eligible Retirement under the Retirement Policy)	Death or Disability	Involuntary Termination without Cause	Change in Control	Change in Control and Qualifying Termination
RSU	Award vests in full.	Award vests on a pro-rata basis.	Award vests on a pro-rata basis.	Award vests on a pro-rata basis.	No effect.	Award vests in full.
CROCE, TSR	Award vests in full, subject to actual performance.	Award vests on a pro-rata basis, subject to actual performance; if retirement occurs on or after the 12-month anniversary of the grant date, the award vests in full, subject to actual performance.	Award vests on a pro-rata basis, subject to actual performance.	Award vests on a pro-rata basis, subject to actual performance.	Award is converted into restricted shares at target level, subject to continued service vesting. (a)	Award vests at greater of target level or actual performance.

(a) No values have been included for the conversion of CROCE and TSR awards at target level upon a change in control because such awards will remain subject

to continued service-based vesting conditions following conversion.

(2) For Ms. Hollub, Mr. Dillon, and Mr. Simmons, assumes an Eligible Retirement under our Retirement Policy because such NEOs have qualified for Eligible

Retirement as of December 31, 2025 based on their age and years of service (actual retirement treatment is subject to their compliance with the other requirements

of our Retirement Policy, as described above). For the other NEOs, assumes retirement with Occidental consent under the terms of outstanding equity awards,

which is not an Eligible Retirement under our Retirement Policy.

(3) Applicable to involuntary terminations without cause as defined in the Severance Plan.

(4) A qualifying termination means a termination by Occidental other than for “cause” or a termination by the NEO for “good reason” (in each case, as defined in the

CIC Severance Plan) within 24 months following the date of the “change in control” (as defined in the CIC Severance Plan).

(5) The dollar amounts shown represent the value realized upon the vesting of the RSU awards upon the occurrence of the applicable potential payment event, which

is equal to the product of Occidental’s year-end closing stock price and the number of shares that vest in accordance with the terms of the applicable award.

(6) No payout of the CROCE awards is shown in connection with the NEOs’ retirement, disability, death or termination without cause because the underlying

performance goals were trending at below threshold performance based on Occidental’s performance through December 31, 2025 . Shares that vest in connection

with these termination scenarios are subject to the actual attainment of the applicable performance goal. In the case of a change in control and qualifying

termination, the dollar amounts shown represent the value realized upon the vesting of the CROCE awards at target performance, which is equal to the product of

the year-end closing stock price and the number of shares that vest in accordance with the terms of the award.

(7) In the case of the NEOs’ retirement, disability, death or termination without cause, the dollar amounts shown represent the value realized upon the vesting of the

2025 TSR awards, which is equal to the product of the year-end closing stock price and the number of shares that vest in accordance with the terms of the award.

No payout of the 2024 TSR awards is shown in connection with the NEOs’ retirement, disability, death or termination without cause because the underlying

performance goals were trending at below threshold performance based on Occidental’s performance through December 31, 2025 , which would result in zero

payout. Shares that vest in connection with these termination scenarios are subject to the actual attainment of the applicable performance goal. In the case of a

change in control and qualifying termination, the dollar amounts shown represent the value realized upon the vesting of the 2024 and 2025 TSR awards at target

performance, which is equal to the product of the year-end closing stock price and the number of shares that vest in accordance with the terms of the award.

(1) The dollar amounts reported are the amounts of “Total” compensation reported in our Summary Compensation Table for our CEO, Vicki Hollub , during each year.

(2) The dollar amounts reported represent the amount of CAP to the CEO, computed in accordance with SEC rules, for each year. The dollar amounts do not reflect the

actual amount of compensation earned by or paid to the CEO during the applicable year. The 2024 CAP amount previously disclosed in our 2025 proxy statement

inadvertently omitted 2022 CROCE and TSR awards that vested during the 2024 compensation year but were not settled until 2025. We have adjusted the CAP

amount for the 2024 compensation year in this column to reflect CAP inclusive of those awards. In accordance with SEC rules, the following adjustments were

made to total compensation to determine the CEO’s compensation actually paid in 2025 and 2024:

Year — 2025	$ 18,055,969	$ 12,298,207	$ 5,564,701	$ 11,322,463
2024	$ 18,535,061	$ 12,640,152	$ ( 1,611,942 )	$ 4,282,967

(a) The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” and “Option Awards” columns in the Summary

Compensation Table on page 49 .

(b) The equity award adjustments for the applicable year were calculated consistent with U.S. generally accepted accounting principles, and the valuation

assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant. These adjustments include the addition (or

subtraction, as applicable) of the following:

Year — 2025	$ 8,819,243	$ ( 2,755,369 )	$ ( 1,014,435 )	$ —	$ 515,262	$ 5,564,701

(3) The dollar amounts reported represent the average of the amounts reported for Occidental’s NEOs as a group (excluding our CEO) in the “Total” column of

the Summary Compensation Table in each applicable year. The NEOs included for purposes of calculating the average amounts in each applicable year are

as follows: (i) for 2025, Mr. Mathew, Mr. Jackson, Mr. Dillon, and Mr. Simmons; (ii) for 2024, Mr. Mathew, Mr. Dillon, Mr. Jackson, and Robert L. Peterson; (iii)

for 2023, Mr. Mathew, Mr. Dillon, Mr. Jackson, Mr. Peterson, and Mr. Simmons; (iv) for 2022, Mr. Peterson, Peter J. Bennett, Mr. Dillon, Mr. Jackson, and

(4) T he dollar amounts reported represent the average amount of CAP to the other NEOs, computed in accordance with SEC rules, for each year. The dollar amounts

do not reflect the actual average amount of compensation earned by or paid to such NEOs during the applicable year. The 2024 average CAP amount previously

disclosed in our 2025 proxy statement inadvertently omitted 2022 CROCE and TSR awards that vested during the 2024 compensation year but were not settled

until 2025. We have adjusted the average CAP amount for the 2024 compensation year in this column to reflect average CAP inclusive of those awards. In

accordance with SEC rules, the following adjustments were made to the average total compensation, as applicable, to determine the compensation actually paid in

2025 and 2024 :

Year — 2025	$ 6,115,905	$ 3,863,794	$ 1,534,998	$ 3,787,109
2024	$ 5,818,111	$ 3,642,188	$ ( 481,936 )	$ 1,693,988

(a) The grant date fair value of equity awards represents the average of the total of the amounts reported in the “Stock Awards” and “Option Awards” columns in

the Summary Compensation Table on page 49 .

(b) The equity award adjustments were calculated consistent with U.S. generally accepted accounting principles, and the valuation assumptions used to calculate

fair values did not materially differ from those disclosed at the time of grant. These adjustments include the addition (or subtraction, as applicable) of

the following:

Year — 2025	$ 2,501,864	$ ( 796,223 )	$ —	$ ( 316,626 )	$ —	$ 145,938	$ 1,534,998
2024	$ 2,459,416	$ ( 1,967,904 )	$ —	$ ( 1,112,307 )	$ —	$ 138,859	$ ( 481,936 )

(5) Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the 1-, 2-, 3-, 4- and 5-year periods beginning December 31, 2020 and

running through each fiscal year end, assuming dividend reinvestment, and the difference between Occidental’s share price at the end and the beginning of the

applicable measurement period by Occidental’s share price on December 31, 2020 .

(6) Amounts reported in this column assume that dividends were reinvested on the day of issuance. The peer group used for this purpose is the performance peer

group as described in “Compensation Discussion and Analysis — Participants in the Executive Compensation Decision-Making Process — Role of Peer Company

Information” on page 39 exclusive of the S&P 500 Index.

(7) The dollar amounts reported represent the amount of net income reflected in Occidental’s audited financial statements for the applicable year.

(8) CROCE is defined by Occidental as cash flows from operating activities before changes in working capital plus any distributions from Western Midstream Partners,

LP which are included in cash flows from investing activities divided by average total debt plus stockholders’ equity (average of the beginning and ending totals for

the applicable period). Management believes that CROCE is useful to investors when comparing our profitability and the efficiency with which management has

employed capital over time relative to other companies. CROCE is not considered to be an alternative to net income reported in accordance with GAAP.

Financial Performance Measures

As described in greater detail in “Compensation Discussion and Analysis” beginning on page 35 , Occidental’s executive compensation

program reflects a variable pay-for-performance philosophy. The metrics that Occidental uses for both our long-term and short-term

incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our shareholders.

The most important financial performance measures used by Occidental to link executive compensation actually paid to Occidental’s

NEOs, for the most recently completed fiscal year, to Occidental’s performance are as follows:

► Cash Return on Capital Employed ( CROCE ) (Company-Selected Measure)

► Relative Total Shareholder Return (TSR)

► Total Spend per Barrel

► Free Cash Flow before Working Capital

Pay vs. Performance

Analysis of the Information Presented in the

Pay versus Performance Table

As described in more detail in the “Compensation Discussion and Analysis” beginning on page 35 , Occidental’s executive compensation

program reflects a variable pay-for-performance philosophy. While Occidental utilizes several performance measures to align executive

compensation with company performance, all of those company measures are not presented in the Pay versus Performance table.

Moreover, Occidental generally seeks to incentivize long-term performance, and therefore does not specifically align Occidental’s

performance measures with compensation that is actually paid (as computed in accordance with SEC rules) for a particular year. In

accordance with SEC rules, Occidental is providing the following descriptions of the relationships between information presented in the Pay

versus Performance table.

Pay Ratio

For 2025 , the annual total compensation of the median compensated employee of Occidental was $225,637 ; the annual total

compensation of Ms. Hollub for purposes of this pay ratio disclosure was $18,078,677 ; and the ratio of these amounts is approximately

80 to 1. This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on Occidental’s payroll records

and the methodology described below.

Pay Ratio Methodology. To identify the “median employee” (as defined by SEC rules), as well as to determine the annual total

compensation of the median employee, we used certain permitted assumptions, adjustments and estimates, as described further below.

Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual

total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates

and assumptions that reflect their employee populations and compensation practices, the pay ratio reported by other companies may not

be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and

may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Employee Population. As permitted under SEC rules, we are using the same median employee identified for purposes of the CEO pay

ratio for 2023, as we believe the changes to our employee population and compensation through fiscal year-end 2025 have not

significantly impacted our pay ratio disclosure. We identified the median employee used for 2023, 2024 and 2025 from Occidental’s

employee population as of October 1, 2023. After excluding 398 employees pursuant to the de minimis exemption (as described below),

Occidental’s employee population consisted of 11,948 employees. Under the de minimis exemption, Occidental was permitted to exclude

up to 5% of its total employees who are non-U.S. employees. Occidental relied on this exemption to exclude the employee populations of

the following jurisdictions, which collectively accounted for less than 5% of Occidental’s total employee population of 12,346 as of

October 1, 2023: Chile (103); Canada (95); United Arab Emirates (76); Bolivia (63); United Kingdom (24); Algeria (13); Singapore (6);

Belgium (4); Colombia (4); Hong Kong (4); Japan (2); Mexico (2); Brazil (1); and Côte d’Ivoire (1).

Compensation Measure to Identify Median Employee. To identify the median employee, we used the annual salary or wages of each

employee as of October 1, 2023, plus any annual bonus paid to each employee during 2023, each as reported in Occidental’s

payroll systems.

Total Compensation in 2025 . We calculated the median employee’s compensation for 2025 in accordance with the requirements of

Item 402 of Regulation S-K, which is equal to the amount of the median employee’s compensation for 2025 that would have been reported

in the Summary Compensation Table on page 49 , plus Occidental’s contributions for the median employee’s non-discriminatory health and

welfare benefits. With respect to the annual total compensation of Ms. Hollub, we used the amount reported in the “Total” column of the

Summary Compensation Table on page 49 , plus the contributions identified above for the median employee, to the extent applicable .

RATIFICATION OF

SELECTION OF KPMG

AS OCCIDENTAL’S

INDEPENDENT AUDITOR

Audit Related Matters

Independence of KPMG

The Audit Committee of the Board of Directors of Occidental oversees the appointment, compensation, performance and retention of the

company’s independent registered public accounting firm that audits the consolidated financial statements of Occidental and its

subsidiaries and internal control over financial reporting. The Audit Committee has selected KPMG LLP (KPMG) to continue to serve as

Occidental’s independent registered public accounting firm for the year ending December 31, 2026 . KPMG has audited Occidental’s

financial statements since 2002. A member of that firm is expected to be present at the 2026 Annual Meeting, will have an opportunity to

make a statement, if so desired, and is expected to be available to respond to appropriate questions.

The Audit Committee annually evaluates KPMG’s performance and independence in determining whether to retain KPMG or engage a

different independent registered public accounting firm. Many factors contributed to the Audit Committee’s retention of KPMG as

Occidental’s independent auditor, including:

► Execution and quality of KPMG’s historical and recent audit plans;

► Quality of KPMG’s communications with the Audit Committee and management;

► Balance of KPMG’s experience and significant institutional knowledge with refreshment in light of mandatory audit partner rotation and

other changes in team leadership;

► KPMG’s strong quality control procedures;

► KPMG’s independence from Occidental and management; and

► Robust independence controls – internal, via the Audit Committee, and external, including Public Company Accounting Oversight

Board (PCAOB) and SEC oversight, PCAOB inspections, peer reviews, and PCAOB requirements for audit partner rotation.

In accordance with applicable rules on partner rotation, KPMG’s lead partner for the company’s audit was rotated in 2025. KPMG’s

engagement quality review partner for the audit was also changed in 2025. The Audit Committee has been, and will continue to be,

involved in considering the selection of KPMG’s primary engagement partner when there is an engagement partner rotation, which is at

least every five years.

Audit and Non-Audit Services

Pre-Approval Policy and Procedures

The Audit Committee must give prior approval to any management request for any amount or type of service (audit, audit-related and tax

services or, to the extent permitted by law, non-audit services) Occidental’s independent auditor provides to the company. Additionally, the

Audit Committee has delegated to the Audit Committee Chair full authority to approve any such request provided the Audit Committee

Chair presents such approval to the Audit Committee at its next scheduled meeting. All audit and audit-related services rendered by KPMG

in 2025 were pre-approved by the Audit Committee or the Audit Committee Chair before KPMG was engaged for such services. No

services of any kind were approved pursuant to the de minimis exception for non-audit services set forth in Rule 2-01 of Regulation S-X.

Proposal 3: Ratification of Selection of KPMG as Occidental’s Independent Auditor

Audit and Other Fees

KPMG was our independent auditor for the years ended December 31, 2025 and 2024 . The audit fees billed and expected to be billed by

KPMG for, and the fees billed by KPMG for all other services rendered during, the years ended December 31, 2025 and 2024 , were as

follows (in millions):

Services Provided	2025
Audit fees (1)	$ 15.3	$ 16.6
Audit-related fees (2)	$ 0.2	$ 0.2
Tax fees (3)	$ 0.6	$ 0.1
All other fees (4)	$ —	$ 0.2
Total	$ 16.1	$ 17.1

(1) Audit fees include fees necessary to perform the annual audit and quarterly reviews in accordance with generally accepted auditing standards, annual attestation on

internal control over financial reporting and services that generally only the independent auditor can reasonably provide, such as comfort letters, statutory audits,

consents and assistance with, and review of, documents filed with the SEC.

(2) Audit-related fees in 2025 and 2024 related to agreed-upon procedures, a review engagement and an attestation engagement related to our revolving credit facility.

(3) Tax fees in 2025 and 2024 related to tax consulting.

(4) All other fees in 2024 related to real-time system implementation assessment services.

Ratification of Selection of Independent Auditor

As a matter of good corporate governance, the Board of Directors of Occidental submits its Audit Committee’s annual selection of the

independent auditor to our shareholders for ratification. A majority of the shares present or by proxy at the 2026 Annual Meeting and

entitled to vote on this proposal must vote “FOR” the proposal to ratify the auditor selection. Abstentions have the same effect as votes

“AGAINST” the proposal. Your broker may vote your shares on the proposal if you do not give your broker voting instructions, although we

are aware that some brokers are choosing not to exercise this discretionary voting authority. As a result, we recommend you submit your

vote as soon as possible. If the shareholders do not ratify the selection of KPMG, the Audit Committee will consider whether it is

appropriate to select another independent auditor. Even if the shareholders ratify the selection of KPMG, the Audit Committee may select a

different independent auditor at any time during the year if it determines that this would be in the best interests of Occidental and our

shareholders. If KPMG should decline to act or otherwise become incapable of acting or if its retention is discontinued, the Audit

Committee will select another independent auditor.

Report of the Audit Committee

The Audit Committee has reviewed and discussed Occidental’s audited financial statements for the year ended December 31, 2025 ,

including management’s annual assessment of and report on Occidental’s internal control over financial reporting, with management and

KPMG, Occidental’s independent auditor. In addition, the Audit Committee has discussed with KPMG the matters required to be discussed

by the applicable standards of the PCAOB and the SEC. The Audit Committee received from KPMG written disclosures and the letter

regarding its independence as required by the applicable requirements of the PCAOB. The Audit Committee has also considered whether

the provision of non-audit services provided by KPMG to Occidental is compatible with maintaining their independence and has discussed

with KPMG the firm’s independence. Based upon the reports and discussions described in this report, the Audit Committee recommended

to the Board that the audited financial statements be included in Occidental’s Annual Report on Form 10-K for the year ended

December 31, 2025 , to be filed with the SEC.

Respectfully submitted,

Telephone voting is available 24 hours a day, and the procedures are designed to authenticate votes cast by using a personal

identification number located on your proxy card. The procedures permit you to give a proxy to vote your shares and to confirm that

your instructions have been properly recorded. If you vote by telephone, you should not return your proxy card.

► Voting at the Meeting. The 2026 Annual Meeting will be held online. Please have your 16-digit control number on your Notice of

Internet Availability, proxy card or in the voting instructions that accompanied your proxy materials to participate in the 2026 Annual

Meeting by visiting www.virtualshareholdermeeting.com/OXY2026 . You will be able to vote your shares electronically during the 2026

Annual Meeting (other than shares held through our employee benefit plan, which must be voted prior to the meeting).

If your shares are held in street name, your broker or other nominee has enclosed a proxy card for you to use to direct it how to vote your

shares and may also provide additional voting instructions. Please instruct your broker or other nominee how to vote your shares using the

form of proxy you received from it or otherwise in accordance with the voting instructions you receive. Please return your completed proxy

to your broker or other nominee or contact the person responsible for your account so that your vote can be counted. If your broker or

other nominee permits you to provide voting instructions via the Internet or by telephone, you may vote that way as well.

Voting instructions relating to shares of our common stock held in the Occidental Petroleum Corporation Savings Plan must be received no

later than 11:59 p.m. Central Time on the date that is three days prior to the 2026 Annual Meeting, so that the trustee (who votes the

shares on behalf of plan participants) has adequate time to tabulate the voting instructions. Shares held in the Occidental Petroleum

Corporation Savings Plan that are not voted or for which the trustee does not receive timely voting instructions will be voted by the trustee

as directed by the company’s Pension and Retirement Plan Administrative Committee.

5. CAN I REVOKE MY PROXY OR CHANGE MY VOTE?

Yes. You may revoke your proxy or change your vote before the 2026 Annual Meeting by filing a revocation with the Corporate Secretary of

Occidental, by granting a new proxy bearing a later date (which automatically revokes the earlier proxy) whether made via the Internet, by

telephone or by mail, or by attending the 2026 Annual Meeting virtually and voting online during the meeting.

If you hold your shares in street name, you may change your vote by contacting your broker or other nominee and following

their instructions.

Questions and Answers About the Annual Meeting and Voting

6. HOW CAN I ATTEND THE 2026 ANNUAL MEETING?

We have decided to hold the 2026 Annual Meeting solely by means of virtual communications.

You may participate in the 2026 Annual Meeting only if you were a shareholder as of March 10, 2026 , the record date, or if you hold a valid

proxy. You will be able to participate in the 2026 Annual Meeting online and submit your questions during the meeting by visiting

www.virtualshareholdermeeting.com/OXY2026 . You also will be able to vote your shares electronically during the 2026 Annual Meeting

(other than shares held through our employee benefit plan, which must be voted prior to the meeting).

To participate in the 2026 Annual Meeting, you will need the 16-digit control number included on your Notice of Internet Availability, on your

proxy card or in the voting instructions that accompanied your proxy materials. If your shares are held in street name and the voting

instruction form you received from your broker or other nominee indicates that you may vote those shares through the

http://www.proxyvote.com website, then you may access and participate in the 2026 Annual Meeting with the 16-digit access code

indicated on that voting instruction form. Otherwise, shareholders who hold their shares in street name should contact their bank, broker or

other nominee (preferably at least five days before the annual meeting) and obtain a “legal proxy” in order to be able to attend, participate

in or vote at the 2026 Annual Meeting.

The 2026 Annual Meeting webcast will begin promptly at 9:00 a.m. Central Time. We encourage you to access the meeting prior to the

start time. Online check-in will begin at 8:45 a.m. Central Time, and you should allow ample time for the check-in procedures.

7. WHAT IF I HAVE TECHNICAL DIFFICULTIES DURING CHECK-IN OR THE MEETING?

We will have technicians ready to assist you if you have any technical difficulties during check-in or the meeting. If you encounter any

difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted

on the virtual meeting log in page.

8. WHAT CONSTITUTES A QUORUM AT THE 2026 ANNUAL MEETING?

A majority of all outstanding shares entitled to vote at the 2026 Annual Meeting will constitute a quorum, which is the minimum number of

shares that must be present or represented by proxy at the meeting to transact business. Abstentions and broker non-votes will be counted

for purposes of determining whether a quorum is present.

9. WHAT IS THE VOTING REQUIREMENT TO APPROVE EACH OF THE PROPOSALS?

Proposal 1 will be subject to a majority voting standard because the By-laws provide that in an uncontested election, directors are elected

by the majority of votes cast with respect to such director, meaning that the number of votes cast “FOR” a director must exceed the number

of votes cast “AGAINST” that director. You may vote “FOR” or “AGAINST” or “ABSTAIN” when voting for each of the directors. Your broker

or other nominee may not vote your shares on this proposal unless you give voting instructions. Abstentions and broker non-votes have no

effect on the vote.

Proposals 2 and 3 require the affirmative vote of a majority of the shares present in person or by proxy at the 2026 Annual Meeting and

entitled to vote on the subject matter. You may vote “FOR” or “AGAINST” or “ABSTAIN” when voting for each of these proposals.

Abstentions will have the same effect as votes cast “AGAINST” each such proposal and broker non-votes, if any, have no effect on

the vote.

10. WHAT HAPPENS IF I HOLD SHARES IN STREET NAME AND DO NOT SUBMIT VOTING INSTRUCTIONS? WHAT IS A

BROKER NON-VOTE?

If your shares are held in street name, under NYSE rules, brokers are not permitted to vote on certain proposals and may not vote on any

of the proposals unless you provide voting instructions. Therefore, unless you provide specific voting instructions, your shares may not be

represented or voted at the meeting.

A broker non-vote occurs when a broker or other nominee holding shares for a beneficial owner does not vote on a particular proposal

because the broker or other nominee does not have discretionary voting power for that particular item (or has discretionary voting power

but chooses not to exercise it) and has not received instructions from the beneficial owner. Under the NYSE rules that govern brokers who

are voting with respect to shares held in street name, if brokers do not receive specific instructions, brokers may in some cases vote the

shares in their discretion, but are not permitted to vote on certain proposals and may elect not to vote on any of the proposals unless you

provide voting instructions.

11. IS THE EFFECTIVENESS OF ANY OF THE PROPOSALS CONDITIONED ON THE APPROVAL OF ANOTHER PROPOSAL?

None of the proposals recommended by the Board to be adopted are conditioned on the approval of another proposal.

12. HOW CAN I ASK QUESTIONS DURING THE 2026 ANNUAL MEETING?

As part of the 2026 Annual Meeting, we will hold a live question and answer session, during which we intend, time permitting, to answer all

written questions pertinent to Occidental and meeting matters that are submitted before or during the meeting in accordance with the

meeting’s Rules of Conduct, which will be posted on the 2026 Annual Meeting website. Questions may be submitted the day of or during

the meeting through www.virtualshareholdermeeting.com/OXY2026 . Answers to questions that are not addressed during the meeting are

expected to be published on our Investor Relations website shortly after the meeting. Questions and answers may be grouped by topic and

substantially similar questions will be grouped and answered once. We reserve the right to edit or reject questions we deem inappropriate.

13. WHO SHOULD I CONTACT IF I HAVE ANY QUESTIONS OR NEED ASSISTANCE IN VOTING MY SHARES, OR IF I NEED ADDITIONAL

COPIES OF THE PROXY MATERIALS?

If you have any questions, please contact Innisfree M&A Incorporated , Occidental’s proxy solicitor, toll-free at 877-687-1873 (U.S. and

Canada) or 412-232-3651 (all other countries) or collect at 212-750-5833 (banks and brokerage firms) .

This proxy statement and Occidental’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 are available

without charge on Occidental’s website or by writing to the Corporate Secretary’s office at the address above. The Annual Report

contains the consolidated financial statements of Occidental and its subsidiaries and the reports of KPMG LLP, Occidental’s

independent auditor.

Householding of Proxy Materials

The SEC permits Occidental, with your permission, to send a single set of proxy materials to any household at which two or more

shareholders reside if Occidental believes they are members of the same family. This rule is called “householding” and its purpose is to

help reduce printing and mailing costs of proxy materials. To date, the company has not instituted this procedure, but may do so in

the future.

A number of brokerage firms have instituted householding. If you and members of your household have multiple accounts holding shares

of Occidental’s common stock, you may have received a householding notification from your broker. Please contact your broker directly if

you have questions or wish to revoke your decision to household. These options are available to you at any time. If you receive a single set

of proxy materials as a result of householding by your broker and you would like to receive separate copies of the Notice of Internet

Availability, the Notice of Annual Meeting of Shareholders, Proxy Statement or Annual Report, you may submit a request to our Corporate

Secretary at the address above, or by calling the Corporate Secretary’s office at 713-552-8654 .

Voting Instructions and Information

Voting Rights

A Notice of Internet Availability or proxy card is being mailed beginning on March 19, 2026 to each shareholder of record as of the close of

business on March 10, 2026 , which is the record date for the determination of shareholders entitled to receive notice of, attend and vote at

the 2026 Annual Meeting. As of the record date, Occidental had 991,695,181 shares of common stock outstanding. A majority of the

outstanding shares of common stock must be represented at the 2026 Annual Meeting, in person or by proxy, to constitute a quorum and

to transact business. Abstentions and broker non-votes will be counted for purposes of determining whether a quorum is present. You will

have one vote for each share of Occidental’s common stock you own. You may vote online during the 2026 Annual Meeting or by proxy.

Proxies may be submitted by telephone or by Internet at www.proxyvote.com as explained on the Notice of Internet Availability and, if you

received a proxy card or voting information form, by marking, signing and returning the card in the envelope provided. Voting via the

Internet is a valid proxy voting method under the laws of the state of Delaware, Occidental’s state of incorporation. You may not cumulate

your votes.

Pursuant to Occidental’s By-laws, a complete list of registered shareholders entitled to vote at the 2026 Annual Meeting will be open to the

examination of any shareholder during normal business hours for 10 days prior to the 2026 Annual Meeting at Occidental’s headquarters.

Director Election Requirements

Pursuant to Occidental’s By-laws, in an uncontested election, directors are elected by the majority of votes cast with respect to such

director, meaning that the number of votes cast “FOR” a director must exceed the number of votes cast “AGAINST” that director. Your

broker may not vote your shares on this proposal unless you give voting instructions. Abstentions and broker non-votes, if any, have no

effect on the vote. Any director who receives a greater number of votes “AGAINST” his or her election than votes “FOR” in an uncontested

election is expected to promptly tender his or her resignation following certification of the shareholder vote by the Inspector of Elections.

Broker Votes

If your shares are held in street name, under NYSE rules, your broker is not permitted to vote on certain proposals and may not vote on

any of the proposals unless you provide voting instructions. Therefore, unless you provide specific voting instructions, your shares may not

be represented or voted at the meeting.

Solicitation Expenses

The expense of this solicitation will be paid by Occidental. Innisfree M&A Incorporated has been retained to solicit proxies and to assist in

the distribution of proxy materials for a fee estimated at $35,000 plus reimbursement of out-of-pocket expenses. Occidental also will

reimburse banks, brokers, nominees and related fiduciaries for the expense of forwarding soliciting material to beneficial owners of its

Under Occidental’s By-laws, shareholders must follow certain procedures to introduce an item of business at an annual meeting without

the proposal or a qualified representative of the shareholder must present the proposal at the meeting. The chairman of the meeting may

General Information

Director Nominations for the 2027 Annual Meeting

Nominating Policy

It is the policy of the Governance Committee to consider nominees to the Board of Directors recommended by shareholders. Pursuant to

the Nominating Policy, which is available at www.oxy.com/investors/governance/governance-policies/nominations-for-directors/,

shareholder recommendations must be received by the Corporate Secretary of Occidental no earlier than January 1, 2027 and no later

than January 31, 2027 to be considered by the Governance Committee. Each recommendation must include the following information:

As to each person whom the shareholder recommends for election or re-election as a director:

► The name, age, business address and residence address of the person;

► The principal occupation or employment of the person;

► The class or series and number of shares of capital stock of Occidental which are owned beneficially or of record by the person; and

► Any other information relating to the person that is required to be disclosed in solicitations for proxies for election of directors

pursuant to the rules and regulations of the SEC.

As to the shareholder making the recommendation and the beneficial owner, if any, on whose behalf the recommendation is made:

► The name and address of record of such shareholder; and

► The class or series and number of shares of common stock of Occidental which are beneficially owned by the shareholder.

The shareholder’s recommendation must include the recommended person’s written consent to being named as a nominee and to serving

as a director if elected.

In prior years, the Governance Committee has identified director candidates through the use of independent search firms, third-party

recommendations and the recommendations of directors. The Governance Committee anticipates that, if a vacancy on the Board were to

occur, it would use these sources as well as shareholder recommendations to identify candidates.

In deciding if a candidate recommended by a shareholder or identified by another source is qualified to be a nominee, it is the Governance

Committee’s policy to consider:

► Whether the candidate is independent as defined in Occidental’s Corporate Governance Policies and as applied with respect to

Occidental and the shareholder recommending the nominee, if applicable;

► Whether the candidate has the business experience, character, judgment, acumen and time to commit in order to make an ongoing

positive contribution to the Board;

► Whether the candidate would contribute to the Board achieving a diverse and broadly inclusive membership; and

► Whether the candidate has the specialized knowledge or expertise, such as financial or audit experience, necessary to satisfy

membership requirements for committees where specialized knowledge or expertise may be desirable.

If there is a vacancy and the Governance Committee believes that a recommended candidate has strong potential for Board service, the

Governance Committee will arrange an interview with the candidate. Pursuant to its charter, the Governance Committee will not

recommend any candidate to the Board who has not been interviewed by the Governance Committee.

In accordance with its charter, the Governance Committee annually reviews its performance and reports its findings to the Board.

The Governance Committee also assists the Board in performing its self-evaluation, which includes an assessment of whether the Board

has the necessary diversity of skills, backgrounds and experiences to meet Occidental’s ongoing needs.

Advance Notice Procedure to Nominate Candidates

Under Occidental’s By-laws, shareholders may nominate a person for election to the Board at an annual meeting by complying with the

advance notice procedures in the By-laws (including providing the information required under Rule 14a-19) and attending the annual

meeting to make the necessary motion. For the 2027 Annual Meeting of Shareholders, the notice must be received no earlier than

January 1, 2027 and no later than the close of business (5:00 p.m. Central Time) on January 31, 2027 and include the information required

by Article III, Section 2 of the By-laws. However, if the 2027 Annual Meeting is more than 30 days before or after the anniversary of the

date of the 2026 Annual Meeting, the notice must be received by no later than the close of business on the tenth day following the day on

which notice of the date of the 2027 Annual Meeting was mailed or such public disclosure was first made, whichever occurs first.

Proxy Access Procedure to Nominate Candidates

In 2015, with input from shareholders, the Board amended Occidental’s By-laws to permit a group of up to 20 shareholders, owning 3% or

more of Occidental’s outstanding common stock continuously for at least three years, to nominate and include in Occidental’s proxy

materials directors constituting up to 20% of the Board, but not less than two directors, provided that the shareholder(s) and the nominee(s)

meet the requirements in Article III, Section 15 of the By-laws. To be included in the 2027 proxy materials, director nominations pursuant to

Article III, Section 15 must be received no earlier than October 20, 2026 and no later than the close of business (5:00 p.m. Central Time)

on November 19, 2026 .

General Information

Forward-Looking Statements

This proxy statement contains “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities

Litigation Reform Act of 1995, including, but not limited to, statements about Occidental’s expectations, beliefs, plans or forecasts.

Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties, many of

which involve factors or circumstances that are beyond Occidental’s control. Actual results may differ from anticipated results, sometimes

materially, and reported or expected results should not be considered an indication of future performance.

Factors that could cause actual results to differ and that may affect Occidental’s results of operations and financial position appear in Part I,

Item 1A “Risk Factors” of Occidental’s Annual Report and in Occidental’s other filings with the SEC.

Because the factors referred to above could cause actual results or outcomes to differ materially from those expressed or implied in any

forward-looking statements, you should not place undue reliance on any such forward-looking statements. Further, any forward-looking

statement speaks only as of the date of this communication and, unless legally required, Occidental does not undertake any obligation to

update any forward-looking statement, as a result of new information, future events or otherwise.

In addition, statements regarding Occidental’s sustainability efforts, initiatives and strategic objectives are aspirational, are not guarantees

or promises that related goals or targets may be met, and are subject to significant risks and uncertainties. Such statements may be based

on standards for measuring progress that are still developing, internal controls and processes that continue to evolve and definitions,

assumptions, data sources and estimates or measurements that are subject to change in the future, including through rulemaking

or guidanc e.

ANNEX A

Reconciliations to GAAP

This proxy statement refers to o perating cash flow before working capital, capital expenditures (net of noncontrolling interest), free cash

flow before working capital, reserves replacement ratios (all-in and organic) and cash return on capital employed (CROCE), which are

supplemental measures not calculated in accordance with generally accepted accounting principles in the United States (GAAP).

Occidental defines operating cash flow before working capital as operating cash flow less changes in working capital from continuing and

discontinued operations; capital expenditures, net of noncontrolling interest as capital expenditures from continuing and discontinued

operations less contributions from noncontrolling interest; and free cash flow before working capital as operating cash flow before working

capital less capital expenditures, net of noncontrolling interest. These non-GAAP measures are not meant to disassociate those items from

management’s performance, but rather are meant to provide useful information to investors interested in comparing Occidental’s

performance between periods. Reported operating cash flow and capital expenditures are considered representative of management’s

performance over the long term, and operating cash flow before working capital, capital expenditures, net of noncontrolling interest and

free cash flow before working capital are not considered to be alternatives to reported operating cash flow and capital expenditures in

accordance with GAAP.

distributions from Western Midstream Partners, LP which are included in cash flows from investing activities, if any, divided by average

total debt plus total equity (average of the beginning and ending totals for the current period). Management believes that CROCE is useful

to investors when comparing our profitability and the efficiency with which management has employed capital over time relative to other

companies. CROCE is not considered to be an alternative to net income reported in accordance with GAAP.
