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 sequestration 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 $1.3 billion for the three months ended September 30, 2025, compared with segment earnings of $0.9 billion for the three months ended June 30, 2025. Excluding the impact of items affecting comparability, oil and gas segment earnings increased due to higher crude oil sales volumes worldwide and higher domestic oil prices.

Average daily sales volumes increased for the three months ended September 30, 2025, compared to the three months ended June 30, 2025, mainly due to higher production from current year drilling plans in the Midland Basin.

Oil and gas segment earnings were $3.9 billion for the nine months ended September 30, 2025, compared to $4.0 billion for the nine months ended September 30, 2024. Excluding the impact of items affecting comparability, oil and gas segment earnings decreased primarily due to lower crude oil prices, partially offset by higher sales volumes due to a full nine months of production from CrownRock assets in 2025.

Average daily sales volumes increased for the nine months ended September 30, 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 September 30, 2025 were $197 million, compared to $213 million for the three months ended June 30, 2025. The decline in the third quarter of 2025 resulted primarily from lower realized prices and volumes across most product lines, partially offset by favorable raw material costs.

Chemical segment earnings for the nine months ended September 30, 2025 were $595 million, compared to $854 million for the nine months ended September 30, 2024. Excluding items affecting comparability, the decrease in pre-tax income resulted from lower realized pricing across most product lines, primarily PVC, and higher raw material and energy costs.

MIDSTREAM AND MARKETING SEGMENT

Midstream and marketing segment earnings for the three months ended September 30, 2025 were $93 million, compared to segment earnings of $49 million for the three months ended June 30, 2025. Excluding the impact of items affecting comparability, midstream and marketing third quarter results decreased due to lower Waha-to-Gulf-Coast gas spreads and higher expenses due to the increase in activities in the low-carbon ventures businesses, partially offset by higher sulfur prices at Al Hosn and higher WES equity method investment income.

Midstream and marketing segment earnings for the nine months ended September 30, 2025 were $65 million, compared to segment earnings of $714 million for the nine months ended September 30, 2024. Excluding the impact of items affecting comparability, midstream and marketing results increased due to higher sulfur prices at Al Hosn, higher Waha-to-Gulf-Coast gas spreads, and lower long-haul crude transportation costs, partially offset by higher losses from equity method investees and higher expenses due to the increase in activities in the low-carbon ventures businesses.
