Vicki Hollub

President and Chief Executive Officer

It is with great appreciation that I reflect upon Oxy's recent sustainability accomplishments across our energy production, midstream and marketing, essential chemistry and carbon innovation businesses. To achieve Oxy's vision of a sustainable future, we have built an integrated portfolio of assets and infrastructure operated by remarkable people driven by passion to outperform.

Our comprehensive strategy starts with taking care of our people and upholding consistently high standards around the world. On the safety front, our company-wide employee Total Recordable Injury Rate (TRIR) was 0.21 in 2023, a 19% improvement from the previous year, while our contractor TRIR was consistent with our 2022 safety results. We also helped employees seize opportunities across our organization, with more than 20% of U.S. employees making moves through promotion or transfer. We added a new Talent Engagement and Employee Experience team to deliver the best experience possible to employees, and continued our leadership in Diversity, Inclusion and Belonging by hosting over 14 Employee Resource Group events. In June 2024, U.S. News & World Report recognized Oxy as one of its 2024-2025 Best Companies to Work For. Out of 3,000 large, publicly traded companies that were considered for the recognition, Oxy was among only 18% of companies that rated "Best" status. Additionally, we ranked in the #1 spot within the Mining and Raw Materials industry.

Oxy's efforts to decarbonize our own operations and advance technologies that will help others to do the same continues, with a reduction of the company's Scope 1 and Scope 2 greenhouse gas (GHG) emissions of 20.4% since 2019, and a 65.2% reduction in methane emissions over this period. We achieved a 67% reduction in routine flaring for global oil and gas operations from our 2020 baseline, while sustaining zero routine flaring in our domestic operations. To further worldwide industry efforts to reduce global emissions, we became an original signatory to the Oil and Gas Decarbonization Charter (OGDC) and committed funding to the World Bank's Global Flaring and Methane Reduction (GFMR) Partnership at COP28 in Dubai.

We significantly expanded our sustainability-focused investments and partnerships over the past year. These included our acquisition of all the outstanding equity of Carbon Engineering - our Direct Air Capture (DAC) technology partner of five years. Carbon Engineering's groundbreaking research and development will play an important role in our integrated Net-Zero Strategy and position us to accelerate cost reduction among our carbon removal offerings.

Construction of our first Direct Air Capture facility, STRATOS, is underway in Ector County, Texas, and on schedule to be commercially operational in mid-2025. Demonstrating that DAC is becoming an investible technology,

we formed a joint venture with BlackRock, one of the world's leading providers of investment, advisory and risk management services, to develop STRATOS, which will be the world's largest DAC plant when completed. Our 1PointFIve subsidiary is also making significant progress in creating a global market for carbon dioxide

removal credits (CDRs). In July 2024, 1PointFive announced a landmark deal with Microsoft, which agreed to purchase 500,000 metric tons of CDRs, the largest DAC CDR purchase to date. A commitment of this magnitude demonstrates how one of the world's largest corporations is integrating scalable DAC into its net-zero strategy, and the important role this technology will play in achieving global climate targets.

Also in support of our climate strategy, wholly owned Oxy subsidiary TerraLithium formed a joint venture in June 2024 with BHE Renewables, a wholly owned subsidiary of Berkshire Hathaway Energy. This partnership will further advance the demonstration and deployment of our patented Direct Lithium Extraction process and associated technologies to extract and commercially produce high-purity lithium compounds from geothermal brine.

In August 2024, we welcomed our new colleagues from CrownRock to Oxy. The CrownRock acquisition complements Oxy's premier Permian asset base and will enhance our sustainability strategy. Oxy and CrownRock have built leading positions in water recycling in the Midland Basin, and we look forward to integrating our substantial water processing capabilities to further enhance our proactive water stewardship.

We also work closely in the regions surrounding our operations, partnering with educational institutions, workforce development programs and community and environmental advocacy groups to ensure benefits from our projects flow to the local communities and promote greater prosperity. 2024 marks Oxy's 40th anniversary in the Sultanate of Oman where we serve as one of the country's leading international investors. Our 3,330 Omani employees comprise over 25% of our global employee base, and our capital investments and operations drive significant in-country value, contributing to 20,000+ contractor or supplier jobs and life-changing social investments. In the U.S., we expanded local partnerships, ranging from providing lifesaving equipment for first responders in the Permian Basin and supporting food banks across our multi-state operations, to donating more than 72,000 books to underserved communities in our hometown of Houston. We have also sponsored community events and meetings with local organizations to provide information to residents, address their questions and listen to their feedback about how we can extend our legacy as a Partner of Choice®.

Our 2023 progress demanded hard work and innovation by thousands of talented people across the organization. I would like to thank the dedicated Oxy workforce, as well as the communities that host our operations, for making what we do possible. I'd also like to thank our Board of Directors and its Sustainability and Shareholder Engagement Committee for their service and direction as we strive to lead our industries in high- performance oil and gas production, midstream and marketing, essential chemistry and carbon innovation.

About Oxy

Oxy's principal businesses consist of three segments: oil and gas, chemical and midstream and marketing. The oil and gas segment explores for, develops and produces oil (including condensate), natural gas liquids (NGL) and natural gas. Our subsidiary Occidental Chemical Corporation (OxyChem) primarily manufactures and markets basic chemicals and vinyls. The midstream and marketing segment purchases, markets, gathers, processes, transports and stores oil, NGL, natural gas, CO2 and power. It also optimizes its transportation and storage capacity, and invests in entities that conduct similar activities, such as Western Midstream Partners, L.P.

Within the midstream and marketing segment, Oxy Low Carbon Ventures (OLCV) seeks to leverage Oxy's legacy of carbon management in enhanced oil recovery (EOR) to develop Carbon Capture, Utilization and Storage (CCUS) projects, including the commercialization of Direct Air Capture (DAC) technology, invest in other low-carbon technologies intended to reduce greenhouse gas (GHG) emissions from Oxy's operations and strategically partner with other industries to help reduce their emissions.

We conduct operations internationally, with assets primarily in the United States, the Middle East and North Africa. We are one of the largest oil and gas producers in the U.S, including a leading producer in the Permian and Denver-Julesburg (DJ) Basins, and offshore Gulf of Mexico. We are regarded as a premier partner in Oman, the United Arab Emirates and Algeria.

Our Climate Strategy: Building to Net-Zero

In 2020, Oxy was the first U.S. oil and gas company to announce goals to achieve net-zero GHG emissions for our total emissions inventory including use of sold products. These goals include achieving net-zero GHG emissions (i) from our operations and energy use before 2040, with an ambition to do so before 2035, and (ii) from our sold products, with an ambition to do so before 2050.

We currently have several short- and medium-term targets to support these overarching net-zero goals and ambitions. Oxy's HSE&S Principles reflect our ambitious net-zero goals and strategy to advance the goals of the Paris Agreement, our collaboration with host communities in the transition to a net- zero economy, and our drive to provide innovative products, services and solutions to address global challenges.

Our Net-Zero Strategy describes the multiple pathways through which we aim to meet our sustainability goals, achieve a successful net-zero transition and help others to do so. Central to this strategy is our development and commercialization of technologies that lower both GHG emissions from industrial processes and existing atmospheric concentrations of CO2. Oxy believes that carbon removal technologies, including DAC and CCUS, can, given the necessary incentives for their development and deployment, provide essential CO2 reductions to assist the world's transition to a less carbon-intensive economy.

Stakeholder Engagement

Stakeholder engagement is a central activity with us at Oxy and a catalyst for ongoing improvement in our policies, practices and reporting. We work to build trust through regular and transparent communication and engagement with shareholders, employees, policy makers, environmental organizations, business partners and community leaders and neighbors where we operate.

Oxy's stakeholder engagement process includes the identification of key stakeholders, an assessment of stakeholder interests and issues, an evaluation of the community's socioeconomic needs if applicable, and the development and implementation of a stakeholder engagement plan. We use a variety of methods and metrics, such as priority topics assessments and value chain impact mapping, to discern and assess important sustainability issues raised by internal and external stakeholders. Our goal is to understand and proactively address issues to develop beneficial outcomes.

Members of the Board's Sustainability and Shareholder Engagement (S&SE) Committee engage with shareholders periodically, oversee Oxy's shareholder engagement program, and report shareholder views to the Board. We regularly meet with shareholders to hear their views on governance, human capital and Oxy's Net-Zero Strategy, among other ESG topics.

Shareholder engagements in recent years have resulted in enhancements to Oxy's sustainability programs and disclosures such as:

The content coverage of our climate and sustainability reports

Matters related to corporate governance, including the adoption of proxy access and amendments to our charter that facilitate shareholders' ability to act by written consent and call special meetings

The executive compensation program, including the design of the short-term incentive program.

Our President and CEO, members of the Board and our Corporate Secretary, alongside representatives of our Investor Relations, Human Resources and Environmental and Sustainability teams, also regularly engage with a wide range of other stakeholders on sustainability matters pertinent to Oxy-includingclimate-related risks and opportunities. These engagements include our approach to carbon management and the policies, technologies and market mechanisms that advance our net-zero goals and those of other industry sectors. We welcome and consider feedback from shareholders and other stakeholders on our performance, engagement and reporting.

This process informs our sustainability strategy and programs, which helps us to improve transparency and report on the issues that matter most to our stakeholders.

Oxy's strong community engagement promotes deep relationships that benefit our communities, our workforce and our shareholders. We recognize and respect our neighbors and local community members from all backgrounds as stakeholders. Their input provides valuable insight into local needs and interests, ways we can augment our projects by addressing their questions and concerns, and how our presence can enhance the community. Informed by that dialogue, we seek to invest our time and resources in programs and initiatives that support the areas surrounding our operations, with an emphasis on disadvantaged communities, and programs that promote mutually beneficial and inclusive relationships with

our neighbors.

Oxy also engages with host governments, non-governmental organizations (NGOs), non-profit organizations, unions, community leaders, and other stakeholders to advocate for policies that serve the UN Sustainable Development Goals (SDGs) relevant to our businesses and the goals of the Paris Agreement. We believe these collaborations position Oxy, our shareholders and our communities for success and reinforce our reputation as a respected Partner of Choice®.
