•Generated $5.1 billion of operating cash flow from continuing operations and $4.6 billion of operating cash flow before working capital

•Produced 1,433 Mboed globally, exceeding the high end of guidance

•Midstream and marketing pre-tax adjusted income exceeded the high end of guidance

•Reported EPS of $2.75; adjusted EPS from continuing operations of $2.40

HOUSTON — August 5, 2026 — Occidental (NYSE: OXY) today announced results for the second quarter of 2026, including net income attributable to common stockholders of $2.8 billion, or earnings per diluted share (EPS) of $2.75, and adjusted income attributable to common stockholders of $2.4 billion, or adjusted EPS from continuing operations of $2.40.

"Our second quarter results demonstrate the strength of Oxy's resources and the competitive advantages that position us for continued value creation,” said Richard Jackson, President and Chief Executive Officer. “We are unlocking more from our assets through our industry-leading advanced recovery capabilities and differentiated value-based development approach. At the same time, we remain focused on executing from a strong balance sheet, organically improving our resources and continuing to deliver cost efficiencies. Through consistent execution on these priorities, we expect to generate significant free cash flow growth by 2030 and sustainable long-term value for our shareholders."

QUARTERLY RESULTS

Oil and Gas

Pre-tax income from oil and gas totaled $2.8 billion for the second quarter of 2026, compared to $1.0 billion for the first quarter of 2026. Excluding items affecting comparability, the increase was primarily driven by higher realized crude oil prices, partially offset by lower domestic natural gas prices. Second quarter average WTI and Brent marker prices were $92.79 per barrel and $97.06 per barrel, respectively. Average worldwide realized crude oil prices increased 38% from the previous quarter to $96.78 per barrel. Average worldwide realized natural gas liquids prices increased 30% to $24.64 per barrel. Average domestic realized gas prices were negative $1.48 per thousand cubic feet (Mcf).

Total global production averaged 1,433 thousand barrels of oil equivalent per day (Mboed) for the second quarter of 2026, exceeding the high end of guidance, with the Permian and Gulf of America business units outperforming.

Midstream and Marketing

Midstream and marketing reported pre-tax income of $1.3 billion for the second quarter of 2026, compared to a pre-tax loss of $87 million in the previous quarter. Excluding items affecting comparability, midstream and marketing results exceeded the high end of guidance. Quarter-over-quarter improvement was driven by higher crude margins related to the timing of crude sales and higher gas margins from transportation capacity optimizations. WES equity method investment income for the second quarter was $149 million.

Supplemental Non-GAAP Measures

This press release refers to adjusted income - continuing operations, operating cash flow before working capital - continuing operations, capital expenditures, net of noncontrolling interest - continuing operations, free cash flow before working capital - continuing operations and adjusted general and administrative (G&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 - continuing operations and a reconciliation to net income (loss), along with operating cash flow before working capital - continuing operations, capital expenditures, net of noncontrolling interest - continuing operations, free cash flow before working capital - continuing operations and adjusted G&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 - continuing operations, operating cash flow before working capital - continuing operations, capital expenditures, net of noncontrolling interest - continuing operations, free cash flow before working capital - continuing operations and adjusted G&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 - continuing operations is a non-GAAP measure. Occidental defines adjusted income - continuing operations 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 - continuing operations is not considered to be an alternative to net income reported in accordance with GAAP.

Non-GAAP Measures. Operating cash flow before working capital - continuing operations, capital expenditures, net of noncontrolling interest - continuing operations and free cash flow before working capital - continuing operations are non-GAAP measures. Occidental defines operating cash flow before working capital - continuing operations as operating cash flow less working capital from continuing operations. Capital expenditures, net of noncontrolling interest - continuing operations is defined as capital expenditures from continuing operations less contributions from noncontrolling interest. Free cash flow before working capital - continuing operations is defined as operating cash flow before working capital - continuing operations less capital expenditures, net of noncontrolling interest - continuing operations. 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 and capital expenditures are considered representative of management's performance over the long term, and operating cash flow before working capital - continuing operations, capital expenditures, net of noncontrolling interest - continuing operations and free cash flow before working capital - continuing operations are not considered to be alternatives to reported operating cash flow and capital expenditures in accordance with GAAP.
