Portions of this report contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact are “forward-looking statements” for purposes of federal and state securities laws, including, but not limited to: any projections of earnings, revenue or other financial items or future financial position or sources of financing; any statements of the plans, strategies and objectives of management for future operations or business strategy; any statements regarding future economic conditions or performance; any statements of belief; and any statements of assumptions underlying any of the foregoing. Words such as “estimate,” “project,” “predict,” “will,” “would,” “should,” “could,” “may,” “might,” “anticipate,” “plan,” “intend,” “believe,” “expect,” “aim,” “goal,” “target,” “objective,” "commit," "advance," “likely” or similar expressions that convey the prospective nature of events or outcomes are generally indicative of forward-looking statements. You should not place undue reliance on these forward-looking statements, which speak only as of the date of this report unless an earlier date is specified. Unless legally required, Occidental does not undertake any obligation to update, modify or withdraw any forward-looking statements as a result of new information, future events or otherwise.

Actual outcomes or results may differ from anticipated results, sometimes materially. Forward-looking and other statements regarding Occidental's sustainability efforts and aspirations are not an indication that these statements are necessarily material to investors or require disclosure in Occidental's filings with the SEC. In addition, historical, current and forward-looking sustainability-related 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 guidance. Factors that could cause results to differ from those projected or assumed in any forward-looking statement include, but are not limited to: general economic conditions, including slowdowns and recessions, domestically or internationally; Occidental’s indebtedness and other payment obligations, including the need to generate sufficient cash flows to fund operations; Occidental’s ability to successfully monetize select assets and repay or refinance debt and the impact of changes in Occidental’s credit ratings or future increases in interest rates; assumptions about energy markets; global and local commodity and commodity-futures pricing fluctuations and volatility; supply and demand considerations for, and the prices of, Occidental’s products and services; actions by OPEC and non-OPEC oil producing countries; results from operations and competitive conditions; future impairments of Occidental's proved and unproved oil and gas properties or equity investments, or write-downs of productive assets, causing charges to earnings; unexpected changes in costs; government actions (including the effects of announced or future tariff increases and other geopolitical, trade, tariff, fiscal and regulatory uncertainties), war (including the Russia-Ukraine war and conflicts in the Middle East) and political conditions and events; inflation, its impact on markets and economic activity and related monetary policy actions by governments in response to inflation; availability of capital resources, levels of capital expenditures and contractual obligations; the regulatory approval environment, including Occidental's ability to timely obtain or maintain permits or other government approvals, including those necessary for drilling and/or development projects; Occidental's ability to successfully complete, or any material delay of, field developments, expansion projects, capital expenditures, efficiency projects, acquisitions or divestitures; risks associated with acquisitions, mergers and joint ventures, such as difficulties integrating businesses, uncertainty associated with financial projections or projected synergies, restructuring, increased costs and adverse tax consequences; uncertainties and liabilities associated with acquired and divested properties and businesses; uncertainties about the estimated quantities of oil, NGL and natural gas reserves; lower-than-expected production from development projects or acquisitions; Occidental’s ability to realize the anticipated benefits from prior or future streamlining actions to reduce fixed costs, simplify or improve processes and improve Occidental’s competitiveness; exploration, drilling and other operational risks; disruptions to, capacity constraints in, or other limitations on the pipeline systems that deliver Occidental’s oil and natural gas and other processing and transportation considerations; volatility in the securities, capital or credit markets, including capital market disruptions and instability of financial institutions; health, safety and environmental (HSE) risks, costs and liability under existing or future federal, regional, state, provincial, tribal, local and international HSE laws, regulations and litigation (including related to climate change or remedial actions or assessments); legislative or regulatory changes, including changes relating to hydraulic fracturing or other oil and natural gas operations, retroactive royalty or production tax regimes and deep-water and onshore drilling and permitting regulations; Occidental's ability to recognize intended benefits from its business strategies and initiatives, such as Occidental's low-carbon ventures businesses or announced greenhouse gas emissions reduction targets or net-zero goals; changes in government grant or loan programs; potential liability resulting from pending or future litigation, government investigations and other proceedings; disruption or interruption of production or manufacturing or facility damage due to accidents, chemical releases, labor unrest, weather, power outages, natural disasters, cyber-attacks, terrorist acts or insurgent activity; the scope and duration of global or regional health pandemics or epidemics, and actions taken by government authorities and other third parties in connection therewith; the creditworthiness and performance of Occidental's counterparties, including financial institutions, operating partners and other parties; failure of risk management; Occidental’s ability to retain and hire key personnel; supply, transportation and labor constraints; reorganization or restructuring of Occidental’s operations; changes in state, federal or international tax rates, deductions, incentives or credits; and actions by third parties that are beyond Occidental's control.

Additional information concerning these and other factors that may cause Occidental’s results of operations and financial position to differ from expectations can be found in Occidental’s other filings with the SEC, including Occidental’s 2024 Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.

Occidental’s operations, financial condition, cash flows and levels of expenditures are highly dependent on oil prices and, to a lesser extent, NGL and natural gas prices, the Midland-to-Gulf-Coast oil spreads, chemical product prices and inflationary pressures in the macro-economic environment. The average WTI price per barrel for the three months ended March 31, 2025 was $71.42, compared to $70.27 for the three months ended December 31, 2024 and $76.96 for the three months ended March 31, 2024.

Changes in oil prices could result in adjustments to capital investment levels and allocation, which impact production volumes. Oil prices may remain volatile due to geopolitical risks, the evolving macro-economic environment's impact on energy demand, future actions by OPEC and other oil producing countries, and recent tariff actions.

In April 2025, President Trump announced a sweeping tariff policy that imposes a 10% baseline tariff on the majority of imports, with significantly higher reciprocal rates for certain nations. The most significant reciprocal rates have been paused for 90 days as negotiations of trade agreements are currently in progress.

Given the ongoing negotiations, Occidental is not able to assess the impact of any final trade agreements or implemented tariffs on its businesses. However, the implementation of these tariffs could have several implications for Occidental's business operations and financial performance as tariffs may be levied on the Company's suppliers which in turn may increase costs. In addition, OxyChem imports and exports certain products which could be subject to tariffs. Occidental is monitoring the ongoing trade developments with the Company's supply chain team to assess the impact of any applicable tariffs.

STRATEGIC PRIORITIES

Occidental is focused on delivering a unique shareholder value proposition with its portfolio of oil and gas, chemical and midstream and marketing assets as well as its ongoing development of carbon management and storage solutions and GHG emissions reduction efforts. Occidental conducts its operations with a priority on technical expertise, HSE, sustainability and social responsibility. In order to maximize shareholder returns, Occidental will:

■Maintain production base to preserve asset base integrity and longevity;

■Deliver a sustainable and growing dividend;

■Prioritize excess cash flow and proceeds from asset divestitures for deleveraging until principal debt is below $15 billion;

■Enhance its asset base with investments in its cash-generative oil and gas and chemical businesses; and

■Advance technologies and decarbonization solutions to develop sustainable low-carbon businesses.

DEBT

As of March 31, 2025, Occidental’s long-term debt was rated Baa3 by Moody’s Investors Service, BBB- by Fitch Ratings and BB+ by Standard and Poor’s. Any downgrade in credit ratings could impact Occidental's ability to access capital markets and increase its cost of capital. In addition, Occidental or its subsidiaries may be requested, elect to provide or in some cases be required to provide collateral in the form of cash, letters of credit, surety bonds or other acceptable support as financial assurance of their performance and payment obligations under certain contractual arrangements, such as pipeline transportation contracts, oil and gas purchase contracts and certain derivative instruments; certain permits, including with respect to carbon capture, utilization and storage activities; and environmental remediation matters.

In the three months ended March 31, 2025, Occidental used cash on hand and proceeds from asset sales to redeem $465 million of senior notes due 2025 and repaid $50 million of the two-year term loan due 2026. Subsequent to March 31, 2025, but before the date of this filing, Occidental used proceeds from asset sales and the warrant exercise to pay all remaining current maturities of $1.4 billion and long-term maturities of $350 million, leaving principal debt outstanding of $22.1 billion. For information on Occidental's debt activity, see Note 4 - Long-Term Debt in the Notes to Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q for additional information.

As of March 31, 2025, approximately 89% of Occidental's outstanding debt was fixed rate.

WARRANT EXERCISE

On March 3, 2025, Occidental announced an offer to exercise its outstanding publicly traded warrants at a temporarily reduced price of $21.30 per share with an expiration date of March 31, 2025. In April 2025, Occidental issued 41.9 million shares of stock in return for proceeds of approximately $890 million. The incremental fair value of the warrants related to the change in exercise price will be recognized as an equity issuance cost in the second quarter of 2025. The proceeds from the warrant exercise were used to repay near-term debt maturities. See Note 4 - Long Term Debt in the Notes to Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q.

The following table sets forth earnings of each operating segment and corporate items:

(a) Refer to the Items Affecting Comparability table which sets forth items affecting Occidental's earnings that vary widely and unpredictably in nature, timing and amount.

ITEMS AFFECTING COMPARABILITY

The following table sets forth items affecting the comparability of Occidental's earnings that vary widely and unpredictably in nature, timing and amount:

(a) Included amounts from gains (losses) on sales of assets and other, net and income from equity investments and other in the Consolidated Condensed Statement of Operations.

(b) Included amounts from income from equity investments and other in the Consolidated Condensed Statement of Operations.

(c) The three months ended March 31, 2024 included $44 million of financing costs related to the CrownRock Acquisition. The remaining amounts for each period are related to CrownRock transaction costs.

Q1 2025 compared to Q4 2024

Excluding the impact of items affecting comparability, net income for the three months ended March 31, 2025, compared to the three months ended December 31, 2024, increased, driven by higher domestic prices across all products in the oil and gas segment, partially offset by lower sales volumes in the oil and gas segment and lower realized caustic soda and polyvinyl chloride prices along with higher ethylene and natural gas costs in the chemical segment.

Q1 2025 compared to Q1 2024

Excluding the impact of items affecting comparability, net income for the three months ended March 31, 2025, compared to the same period in 2024, increased, driven by higher sales volumes and higher domestic gas and NGL prices in the oil and gas segment, partially offset by lower oil prices in the oil and gas segment and higher ethylene and natural gas prices in the chemical segment.

SELECTED STATEMENTS OF OPERATIONS ITEMS

Q1 2025 compared to Q4 2024

Net sales of $6.8 billion for the three months ended March 31, 2025 remained consistent, compared to $6.8 billion for the three months ended December 31, 2024, as the effect of higher commodity prices was offset by lower sales volumes across all products in the oil and gas segment.

Income tax expense increased to $387 million for the three months ended March 31, 2025, compared to a tax benefit of $49 million primarily resulting from the Passaic environmental reserve adjustment for the three months ended December 31, 2024.

Q1 2025 compared to Q1 2024

Net sales of $6.8 billion increased for the three months ended March 31, 2025, compared to $6.0 billion for the same period in 2024, primarily due to higher volumes across all products and higher domestic natural gas prices, partially offset by lower oil prices in the oil and gas segment.

Depreciation, depletion and amortization of $1.9 billion increased for the three months ended March 31, 2025, compared to $1.7 billion for the same period in 2024, primarily related to increased sales volumes in the Permian Basin from the CrownRock Acquisition.

SEGMENT RESULTS OF OPERATIONS

Occidental’s principal businesses consist of three reporting segments: oil and gas, chemical and midstream and marketing. The oil and gas segment explores for, develops and produces oil and condensate, NGL and natural gas. The chemical segment is operated by our subsidiary OxyChem, which mainly manufactures and markets basic chemicals and vinyls. The midstream and marketing segment purchases, markets, gathers, processes, transports and stores oil (which includes condensate), NGL, natural gas, CO2 and power. It also optimizes its transportation and storage capacity and invests in entities that conduct similar activities such as WES.

The midstream and marketing segment also includes Occidental's low-carbon ventures businesses. Occidental's low-carbon ventures businesses seek to leverage Occidental’s legacy of carbon management experience to develop carbon capture, utilization and storage projects, including the commercialization of direct air capture technology, invest in other low-carbon technologies intended to reduce greenhouse gas emissions from Occidental's operations and strategically partner with other industries to help reduce their emissions.

OIL AND GAS SEGMENT

The following table sets forth the average sales volumes per day for oil and NGL in Mbbl and for natural gas in MMcf:

(a) Natural gas volumes have been converted to Boe based on energy content of six Mcf of gas to one barrel of oil. Conversion to Boe does not necessarily result in price equivalency.

The following table presents information about Occidental's average realized prices and index prices:

Q1 2025 compared to Q4 2024

Oil and gas segment earnings were $1.7 billion for the three months ended March 31, 2025, compared with segment earnings of $1.2 billion for the three months ended December 31, 2024. Excluding the impact of items affecting comparability, oil and gas segment earnings increased due to higher domestic prices across all products and higher other revenues, partially offset by lower sales volumes.

Average daily sales volumes decreased for the three months ended March 31, 2025, compared to the three months ended December 31, 2024, primarily due to ethane rejection in the Rockies and delays due to weather and third-party facility disruptions in the Permian and maintenance in GOA.

Q1 2025 compared to Q1 2024

Oil and gas segment earnings were $1.7 billion for the three months ended March 31, 2025, compared to $1.2 billion for the three months ended March 31, 2024. Excluding the impact of items affecting comparability, oil and gas segment earnings increased primarily due to higher domestic sales volumes and natural gas and NGL prices, partially offset by lower domestic crude oil prices and higher depreciation expense from the CrownRock Acquisition.

Average daily sales volumes increased for the three months ended March 31, 2025, compared to the same period in 2024, mainly due to the CrownRock Acquisition.

The following table presents an analysis of the impacts of changes in average realized prices and sales volumes with regard to Occidental's domestic and international oil and gas revenue:

(a) Includes the impact of international production sharing contracts.

(b) Excludes "other" oil and gas revenue. See Note 2 - Revenue in the Notes to Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q for additional information regarding other revenue.

CHEMICAL SEGMENT

Q1 2025 compared to Q4 2024

Chemical segment earnings for the three months ended March 31, 2025 were $185 million, compared to $270 million for the three months ended December 31, 2024. Excluding items affecting comparability, the decrease was due primarily to lower realized caustic soda and polyvinyl chloride prices along with higher ethylene and natural gas costs.

Q1 2025 compared to Q1 2024

Chemical segment earnings for the three months ended March 31, 2025 were $185 million, compared to $254 million for the three months ended March 31, 2024. Excluding items affecting comparability, the decrease in first quarter results reflected lower prices across most product lines except caustic soda and higher ethylene and natural gas costs.

MIDSTREAM AND MARKETING SEGMENT

Q1 2025 compared to Q4 2024

Midstream and marketing segment losses for the three months ended March 31, 2025 were $77 million, compared to segment losses of $134 million for the three months ended December 31, 2024. Excluding the impact of items affecting comparability, midstream and marketing first quarter results increased due to higher crude margins related to the timing impact of crude sales and higher sulfur prices at Al Hosn.

Q1 2025 compared to Q1 2024

Midstream and marketing segment losses for the three months ended March 31, 2025 were $77 million, compared to segment losses of $33 million for the three months ended March 31, 2024. Excluding the impact of items affecting comparability, the increase in midstream and marketing first quarter results reflected higher gas margins from transportation capacity optimization in the Permian and higher sulfur prices at Al Hosn, partially offset by lower margins related to the timing impact of crude sales.

The following table sets forth the calculation of the worldwide effective tax rate for income:

Occidental estimates its annual effective income tax rate in recording its quarterly provision for income taxes in the various jurisdictions in which Occidental operates, adjusted for certain discrete items. Each quarter, Occidental updates these rates and records a cumulative adjustment to its income taxes by applying the rates to the pre-tax income excluding certain discrete items. Occidental’s quarterly estimate of its effective tax rates can vary significantly based on various forecasted items, including future commodity prices, capital expenditures, expenses for which tax benefits are not recognized and the geographic mix of pre-tax income and losses.

The worldwide effective tax rates for the periods presented in the table above are primarily driven by Occidental's jurisdictional mix of income. U.S. income is taxed at a U.S. federal statutory rate of 21%, while international income is subject to tax at statutory rates as high as 55%.

INFLATION REDUCTION ACT AND PILLAR TWO

For more information on the potential impacts to Occidental related to the IRA and Pillar Two initiative, see Note 7 - Income Taxes.

SOURCES AND USES OF CASH

As of March 31, 2025, Occidental's sources of liquidity included $2.6 billion of cash and cash equivalents, $4.15 billion of borrowing capacity under its RCF, and $600 million of available borrowing capacity on its receivables securitization facility. In February 2024, Occidental entered into a Third Amended and Restated Credit Agreement for the RCF extending the maturity date to June 30, 2028, and in May 2024, Occidental amended the RCF to increase its borrowing capacity by an additional $150 million to $4.15 billion. In July 2024, Occidental amended and extended the maturity date of its existing receivables securitization facility to July 30, 2027, maintaining $600 million of available borrowing capacity. There were no borrowings outstanding on Occidental's RCF or receivables securitization facility as of March 31, 2025.

Operating Cash Flows

Operating cash flow from continuing operations was $2.1 billion for the three months ended March 31, 2025, compared to $2.0 billion for the three months ended March 31, 2024. The increase in operating cash flow from continuing operations, compared to the same period in 2024, was primarily due to higher sales volumes, including volumes from the CrownRock Acquisition and GOA, offset primarily by higher use of working capital due to timing of federal tax payments and other current payables.

Investing Cash Flows

Occidental’s net cash used by investing activities was $0.7 billion for the three months ended March 31, 2025, compared to $1.8 billion for the three months ended March 31, 2024. Investing activities included $1.3 billion in divestitures of non-core oil and gas assets. See Note 5 - Acquisitions and Divestitures in the Notes to Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q for additional information.

Capital expenditures, of which the majority were for the oil and gas segment, were $1.9 billion for the three months ended March 31, 2025, compared to $1.8 billion for the three months ended March 31, 2024.

Financing Cash Flows

Occidental’s net cash used by financing activities was $0.9 billion for the three months ended March 31, 2025, which included payments of long-term debt of $0.5 billion and payments of common and preferred dividends of $0.4 billion. See Note 4 - Long-Term Debt in the Notes to Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q.

Cash used in financing activities for the three months ended March 31, 2024 was $0.3 billion, which was primarily related to cash dividends.

Occidental’s Zero Coupons can be put to Occidental in October of each year, in whole or in part, for the then accreted value of the outstanding Zero Coupons. The Zero Coupons can next be put to Occidental in October 2025, which, if put in whole, would require a payment of approximately $381 million at such date. Occidental currently has the ability to meet this obligation and may use available capacity under the RCF and other committed facilities to satisfy the put should it be exercised.

As of the date of this filing, Occidental was in compliance with all covenants in its financing agreements. As of the date of this filing, Occidental has no debt maturities due in 2025, $2.9 billion in 2026, $1.5 billion in 2027 and $17.7 billion thereafter. Occidental currently expects its cash on hand, operating cash flows and funds available from the RCF and other committed facilities to be sufficient to meet its near-term debt maturities, operating expenditures, capital expenditures and other obligations for the next 12 months from the date of this filing.

Occidental or its subsidiaries have provided financial assurances through a combination of cash, letters of credit and surety bonds. As of March 31, 2025, Occidental had not issued any letters of credit under the RCF or other committed facilities. For additional information, see Risk Factors in Part I, Item 1A of Occidental’s 2024 Form 10-K.

Occidental’s operations are subject to stringent federal, regional, state, provincial, tribal, local and international laws and regulations related to improving or maintaining environmental quality. Occidental’s environmental compliance costs have generally increased over time and are expected to rise in the future. Occidental factors environmental expenditures for its operations as an integral part of its business planning process.

The laws that require or address environmental remediation, including CERCLA and similar federal, regional, state, provincial, tribal, local and international laws, may apply retroactively and regardless of fault, the legality of the original activities or the current ownership or control of sites. Occidental or certain of its subsidiaries participate in or actively monitor a range of remedial activities and government or private proceedings under these laws with respect to alleged past practices at Third-Party, Currently Operated, and Closed or Non-Operated Sites, which categories may include NPL Sites. Remedial activities may include one or more of the following: investigation involving sampling, modeling, risk assessment or monitoring; cleanup measures including removal, treatment or disposal; or operation and maintenance of remedial systems. The environmental proceedings seek funding or performance of remediation and, in some cases, compensation for alleged property damage, natural resource damages, punitive damages, civil penalties, injunctive relief and government oversight costs.

See Note 8 - Environmental Liabilities and Expenditures in the Notes to Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q and the Environmental Liabilities and Expenditures section of Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2024 Form 10-K for additional information regarding Occidental’s environmental liabilities and expenditures.

Occidental accrues reserves for outstanding lawsuits, claims and proceedings when it is probable that a liability has been incurred and the liability can be reasonably estimated. Occidental has disclosed its reserve balances for environmental remediation matters and its estimated range of reasonably possible additional losses for such matters. See Note 8 - Environmental Liabilities and Expenditures and Note 9 - Lawsuits, Claims, Commitments and Contingencies in the Notes to Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q for further information.

For the three months ended March 31, 2025, there were no material changes in the information required to be provided under Item 305 of Regulation S-K included under Item 7A, Quantitative and Qualitative Disclosures About Market Risk in the 2024 Form 10-K.

Occidental's President and Chief Executive Officer and its Senior Vice President and Chief Financial Officer supervised and participated in Occidental's evaluation of the effectiveness of its disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report. Based upon that evaluation, Occidental's President and Chief Executive Officer and Senior Vice President and Chief Financial Officer concluded that Occidental's disclosure controls and procedures were effective as of March 31, 2025.

There has been no change in Occidental’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended March 31, 2025 that has materially affected, or is reasonably likely to materially affect, Occidental’s internal control over financial reporting.

Part II Other Information

Item 1. Legal Proceedings

Occidental has elected to use a $1 million threshold for disclosing certain proceedings arising under federal, state or local environmental laws when a governmental authority is a party and potential monetary sanctions are involved. For information regarding legal proceedings, see Note 9 - Lawsuits, Claims, Commitments and Contingencies in the Notes to Consolidated Condensed Financial Statements in Part I, Item 1 of this Form 10-Q.

There have been no material changes from the risk factors included under Part I, Item 1A of Occidental’s 2024 Form 10-K for the year ended December 31, 2024.

During the three months ended March 31, 2025, no director or Section 16 officer of Occidental adopted or terminated any Rule 10b5-1 trading arrangements or non-Rule 10b5-1 trading arrangements (in each case, as defined in Item 408(a) of Regulation S-K).
