HOUSTON, March 05, 2026 - Occidental (NYSE: OXY) today announced the early tender results, as set forth in the table below, of its offers to purchase for cash (collectively, the "Tender Offers" and each a "Tender Offer") its Zero Coupon Senior Notes due 2036 (the "0.000% 2036 Notes"), 6.125% Senior Notes due 2031 (the "6.125% 2031 Notes"), 6.625% Senior Notes due 2030 (the "6.625% 2030 Notes"), 7.200% Debentures due 2029 (the "7.200% 2029 Debentures") and 7.950% Debentures due 2029 (the "7.950% 2029 Debentures" and, together with the 0.000% 2036 Notes, the 6.125% 2031 Notes, the 6.625% 2030 Notes and the 7.200% 2029 Debentures, the "Notes") and Consent Solicitations (as defined below). In connection therewith, Occidental further announced that it is increasing the maximum aggregate principal amount of Notes it will accept for purchase (as amended herein, the "Aggregate Cap"), from the previously announced amount of $700,000,000 to $1,200,000,000. The $58,000,000 maximum aggregate principal amount of the 0.000% 2036 Notes it will accept for purchase (the "Sub-Cap") has not been increased.

The Tender Offers and Consent Solicitations are being made pursuant to the terms and conditions described in Occidental's Offer to Purchase and Consent Solicitation Statement, dated February 19, 2026, as amended by this press release (the "Offer to Purchase"). As set forth in the Offer to Purchase, Occidental reserves the right, but is under no obligation, to further increase the Aggregate Cap or to increase the Sub-Cap at any time, subject to applicable law. Capitalized terms used but not defined herein have the meanings ascribed thereto in the Offer to Purchase.

According to the information received from Global Bondholder Services Corporation, the Tender Agent and Information Agent for the Tender Offers and Consent Solicitations, as of 5:00 p.m., New York City time, on March 4, 2026 (such date and time, the "Early Tender Time"), Occidental had received, and informed Global Bondholder Services Corporation it had accepted, valid tenders from holders of the Notes as outlined in the table below.

The purchase of all Notes validly tendered and not validly withdrawn in the Tender Offers as of the Early Tender Time would cause Occidental to purchase an aggregate principal amount of Notes that exceeds the Aggregate Cap. Accordingly, Occidental has accepted for purchase a portion of the tendered 6.625% 2030 Notes and all tendered Notes with a higher Acceptance Priority Level and has not accepted for purchase any of the tendered 7.200% 2029 Debentures or 7.950% 2029 Debentures in accordance with the proration procedures and other Acceptance Priority Procedures set forth in the Offer to Purchase.

As the Tender Offers were fully subscribed up to the Aggregate Cap as of the Early Tender Time, holders who validly tender Notes after the Early Tender Time, but before the Expiration Date, will not have any of such Notes accepted for payment unless Occidental further increases the Aggregate Cap. The early settlement date for Notes validly tendered and not validly withdrawn at or prior to the Early Tender Time and accepted for purchase will be March 9, 2026 (the "Early Settlement Date"), subject to the satisfaction or waiver of all conditions to the Tender Offers and Consent Solicitations described in the Offer to Purchase.

Holders of Notes that were validly tendered and not validly withdrawn at or prior to the Early Tender Time and have been accepted for purchase pursuant to the applicable Tender Offer will receive the applicable Total Consideration for the applicable series of Notes, which includes the applicable early tender premium for such series of Notes as set forth in the table above (the "Early Tender Premium"), together with accrued but unpaid interest, if any, on such Notes from the last interest payment date with respect to such Notes to, but not including, the Early Settlement Date. In accordance with the procedures set forth in the Offer to Purchase, the Total Consideration will be determined by reference to the applicable fixed spread specified in the table above plus the yield of the applicable U.S. Treasury security specified in the table above (the "Reference Treasury Security"), based on the bid-side price of such Reference Treasury Security as quoted on the applicable Bloomberg Reference Page set forth in the table above at 10:00 a.m., New York City time, on March 5, 2026, and will be announced by Occidental promptly thereafter. The Tender Offers and Consent Solicitations will expire at 5:00 p.m., New York City time, on March 19, 2026, unless earlier extended or terminated by Occidental.

As part of the Tender Offers, Occidental also solicited consents (the "Consent Solicitations") from the holders of the 6.125% 2031 Notes, the 6.625% 2030 Notes, the 7.200% 2029 Debentures and the 7.950% 2029 Debentures (collectively, the "Consent Notes") for certain proposed amendments (the "Proposed Amendments") described in the Offer to Purchase that would, among other things, eliminate certain of the covenants contained in the indenture governing the Consent Notes with respect to the applicable series of Consent Notes and change the minimum notice period for notice of redemption to holders in respect of such applicable series of Consent Notes to 5 business days prior to the applicable redemption date. Adoption of the Proposed Amendments with respect to each series of Consent Notes requires the requisite consent applicable to such series of Consent Notes as described in the Offer to Purchase (the "Requisite Consent"). As of the Early Tender Time, the Requisite Consent required to approve the Proposed Amendments with respect to the 6.125% 2031 Notes has been received, and the Company intends to execute a supplemental indenture to the indenture governing such series of Notes on the Early Settlement Date. As of the Early Tender Time, the Requisite Consent required to approve the Proposed Amendments with respect to the 6.625% 2030 Notes, the 7.200% 2029 Debentures and the 7.950% 2029 Debentures was not obtained by the Company and, therefore, the indenture governing such Notes will not be amended and will remain in effect in its present form.
