In the six months ended June 30, 2025, and through the date of this filing, Occidental sold non-core proved and unproved U.S. onshore oil and gas working interests for a total of approximately $730 million. In addition, in the first quarter of 2025, Occidental sold non-operated proved and unproved royalty and mineral interests in the DJ Basin for approximately $900 million. The difference in the assets' net book value and adjusted purchase price was treated as a normal retirement, and as a result no gain or loss was recognized.

In July 2025, Occidental entered into an agreement to sell certain gas gathering assets in the Permian Basin for approximately $580 million. The agreement is subject to customary closing conditions and the receipt of regulatory approval, including the expiration or termination of the waiting period (and any extensions thereof) under the HSR Act.
