Indenture and the 2034 Notes

On July 13, 2026, Talos Energy Inc., a Delaware corporation (the “Company”), Talos Production Inc., a Delaware corporation and a wholly owned subsidiary of the Company (the “Issuer”), certain of the Issuer’s subsidiaries (the “Subsidiary Guarantors” and, together with the Company, the “Guarantors”) and Wilmington Trust, National Association, as trustee and as collateral agent, entered into an indenture (the “Indenture”), pursuant to which the Issuer issued $800,000,000 in aggregate principal amount of the Issuer’s 8.000% Second-Priority Senior Secured Notes due 2034 (the “2034 Notes”). The 2034 Notes are unconditionally guaranteed on a senior unsecured basis by the Company and on a second-priority senior secured basis by each of the Subsidiary Guarantors and will be unconditionally guaranteed on the same basis by certain of the Issuer’s future subsidiaries. The 2034 Notes are secured on a second-priority basis by liens on substantially the same collateral (the “Collateral”) as the Issuer’s existing first-priority obligations under its senior reserve-based revolving credit facility. Those security interests are subject to intercreditor agreements governing the rights and priorities of the secured parties under the Indenture and the holders of certain other indebtedness outstanding on July 13, 2026 and that may be incurred in the future.

The Issuer has used, or intends to use, the net proceeds from the sale of the 2034 Notes to (i) fund a portion of the cash consideration for the Company’s pending acquisition of certain oil and gas properties and related assets located in the Outer Continental Shelf in the Mississippi Canyon area of the Gulf of America, including interests in the Na Kika and Coulomb deepwater producing assets (the “Gulf of America Acquisition”), pursuant to that certain purchase and sale agreement, dated as of June 30, 2026 (the “Purchase Agreement”), by and among Talos Ocho Energy LLC, a Delaware limited liability company and a direct wholly owned subsidiary of the Issuer, RE Fund V Holdco II Infrastructure, LLC, a Delaware limited liability company and an affiliate of Ridgewood Energy Corporation, and Shell Offshore Inc., a Delaware corporation (“Seller”), (ii) fund the redemption of all of the Issuer’s outstanding 9.000% Second-Priority Senior Secured Notes due 2029 (the “9.000% Notes”), and (iii) pay related fees and expenses. The Issuer intends to use any remaining net proceeds for general corporate purposes.

If (i) the consummation of the Gulf of America Acquisition does not occur on or before the “Outside Date,” as such term is defined in the Purchase Agreement as in effect as of July 1, 2026, (ii) prior thereto, the Issuer notifies the trustee that it will not pursue the consummation of the Gulf of America Acquisition, or (iii) the preferential right to purchase in favor of BP (the “Preferential Right”) with respect to Seller’s 50% working interests in the Na Kika platform and related Kepler, Ariel, Fourier and Herschel fields comprising a portion of the assets to be acquired pursuant to the Purchase Agreement is exercised, the Issuer will be required to redeem $175,000,000 aggregate principal amount of the 2034 Notes then outstanding (such redemption, the “Special Mandatory Redemption”) at a redemption price equal to 100% of the principal amount of the 2034 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the date upon which such 2034 Notes will be redeemed; provided that the Issuer will not be required to effect more than one Special Mandatory Redemption. The “Outside Date” under the Purchase Agreement is December 31, 2026.

Interest and Maturity

The 2034 Notes will mature on July 15, 2034, and interest on the 2034 Notes is payable semi-annually in arrears on each January 15 and July 15, commencing January 15, 2027, to holders of record on the January 1 and July 1 immediately preceding the related interest payment date, at a rate of 8.000% per annum.

In addition, prior to July 15, 2029, the Issuer may redeem the 2034 Notes, in whole at any time or in part from time to time, upon not less than 10 or more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the 2034 Notes redeemed, plus an applicable make-whole premium and accrued and unpaid interest, if any, to, but excluding, the redemption date.
