OCCIDENTAL PETROLEUM CORP DE

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, CO 2 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:

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.

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

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.

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

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.

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.
