PRESS RELEASE

•Announcing $950 million of additional divestitures since the start of the second quarter of 2025, of which approximately $370 million has already closed. Occidental has repaid $3.0 billion of debt year-to-date through a combination of asset sales, organic cash flow and proceeds from warrants exercised
•Operating cash flow of $3.0 billion and operating cash flow before working capital of $2.6 billion
•Capital spending of $2.0 billion and contributions from noncontrolling interest of $51 million resulted in quarterly free cash flow before working capital of $0.7 billion
•Total company production above the mid-point of guidance with 1,400 Mboed
•Midstream and marketing exceeded the high-end of guidance for pre-tax adjusted income
•Earnings per diluted share of $0.26 and adjusted earnings per diluted share of $0.39
•Reducing the mid-point of 2025 capital guidance by $100 million and international operating costs by $50 million, driven by continued operational efficiency gains. Year-to-date, Occidental has realized or identified $500 million in capital and operating cost reductions from the original guidance

HOUSTON — August 6, 2025 — Occidental (NYSE: OXY) today announced net income attributable to common stockholders of $288 million, or $0.26 per diluted share, and adjusted income attributable to common stockholders of $396 million, or $0.39 per diluted share, for the second quarter of 2025.

"Continued well performance leadership and a focus on enhanced operational efficiencies enabled us to generate strong financial results in the second quarter," said President and Chief Executive Officer Vicki Hollub. "By unlocking lower cost resources, accelerating our deleveraging efforts and advancing our strategic growth projects, we have positioned our portfolio to deliver long-term value."


QUARTERLY RESULTS
Oil and Gas
Oil and gas pre-tax income was $934 million for the second quarter of 2025. Excluding items affecting comparability, the decrease in second quarter oil and gas income, compared to the first quarter of 2025, was due to lower commodity prices, partially offset by higher crude oil volumes and lower lease operating expense. For the second quarter of 2025, average WTI and Brent marker prices were $63.74 per barrel and $66.59 per barrel, respectively. Average worldwide realized crude oil prices decreased by 10% from the prior quarter to $63.76 per barrel. Average worldwide realized natural gas liquids prices decreased by 20% from the prior quarter to $20.71 per barrel. Average domestic realized gas prices decreased by 45% from the prior quarter to $1.33 per thousand cubic feet (Mcf).

Total average global production for the second quarter of 2025 was 1,400 thousand barrels of oil equivalent per day (Mboed). Average production for Permian, Rockies & Other Domestic, Gulf of America and International were 770 Mboed, 272 Mboed, 125 Mboed and 233 Mboed, respectively.



OxyChem
OxyChem pre-tax income was $213 million for the second quarter of 2025. Excluding items affecting comparability, second quarter OxyChem income was relatively unchanged compared to the first quarter of 2025 and reflected negative inventory adjustments, offset by improved export demand for caustic soda and polyvinyl chloride (PVC).

Midstream and Marketing
Midstream and marketing pre-tax income was $49 million for the second quarter of 2025. Excluding items affecting comparability, the second quarter midstream and marketing results exceeded the high end of guidance. Compared to the first quarter of 2025, the increase in second quarter midstream and marketing results reflected higher gas marketing margins from transportation capacity optimization in the Permian and higher sulfur prices at Al Hosn. WES equity method investment income for the second quarter was $150 million.

Supplemental Non-GAAP Measures
This press release refers to adjusted income (loss), operating cash flow before working capital, capital expenditures, net of noncontrolling interest, free cash flow before working capital and adjusted selling, general and administrative (SG&A), other operating and non-operating expenses, which are supplemental measures not calculated in accordance with generally accepted accounting principles in the United States (GAAP). These non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as an alternative to the comparable GAAP financial measures. Definitions of adjusted income (loss) and a reconciliation to net income (loss), along with operating cash flow from continuing operations before working capital, capital expenditures, net of noncontrolling interest, free cash flow before working capital and adjusted SG&A, other operating and non-operating expenses and a reconciliation to the comparable GAAP financial measures, are included in the financial schedules of this press release. Occidental’s definition of adjusted income (loss), operating cash flow from continuing operations before working capital, capital expenditures, net of noncontrolling interest, free cash flow before working capital and adjusted SG&A, other operating and non-operating expenses may differ from similarly titled measures provided by other companies in our industry and as a result may not be comparable.

(a) Non-GAAP Measure. Adjusted income is a non-GAAP measure. Occidental defines adjusted income as net income excluding the effects of significant transactions and events that affect earnings but vary widely and unpredictably in nature, timing and amount. These events may recur, even across successive reporting periods. This non-GAAP measure is not meant to disassociate those items from management’s performance, but rather is meant to provide useful information to investors interested in comparing Occidental’s earnings performance between periods. Reported net income is considered representative of management’s performance over the long term, and adjusted income is not considered to be an alternative to net income reported in accordance with GAAP.

Reported net income is considered representative of management’s performance over the long term, and adjusted income is not considered to be an alternative to net income reported in accordance with GAAP. The reported EPS (GAAP) calculations do not include dilutive effect of potential issuance of common stocks as their effect is anti-dilutive since Occidental generated net losses from continuing operations.

(a) Non-GAAP Measures. Operating cash flow from continuing operations before working capital, capital expenditures, net of noncontrolling interest and free cash flow before working capital are non-GAAP measures. Occidental defines operating cash flow from continuing operations before working capital as operating cash flow from continuing operations less working capital. Capital expenditures, net of noncontrolling interest is defined as capital expenditures less contributions from noncontrolling interest. Free cash flow before working capital is defined as operating cash flow from continuing operations 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 from continuing operations and capital expenditures are considered representative of management's performance over the long term, and operating cash flow from continuing operations 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 from continuing operations and capital expenditures in accordance with GAAP.
