GLOSSARY

As used in this offering memorandum, unless the context indicates or otherwise requires, the following terms have the following meanings.

“Coulomb Interest” means Seller’s 100% working interest and operatorship in the Coulomb field.

“Gulf of America Acquisition” means the transactions contemplated by the Purchase Agreement.

“Na Kika Interests” means Seller’s 50% working interests in the BP-operated Na Kika platform and related Kepler, Ariel, Fourier and Herschel fields comprising a portion of the PSA Assets.

“Preferential Right” means the preferential right to purchase the Na Kika Interests in favor of BP.

“PSA Assets” means certain oil and gas properties and related assets located in the Outer Continental Shelf in the Mississippi Canyon area of the Gulf of America to be acquired by the Buyers (as defined below, in the definition of “Purchase Agreement”) pursuant to the Purchase Agreement, including the Coulomb Interest and the Na Kika Interests.

“Purchase Agreement” means that certain purchase and sale agreement, dated as of June 30, 2026, by and among Talos Ocho Energy LLC, a Delaware limited liability company and a direct wholly owned subsidiary of the Issuer (“Talos Ocho”), RE Fund V Holdco II Infrastructure, LLC, a Delaware limited liability company and an affiliate of Ridgewood Energy Corporation (together with Talos Ocho, the “Buyers”), and Shell Offshore Inc., a Delaware corporation (“Seller”), pursuant to which the Buyers will each acquire an undivided 50% interest in the PSA Assets and Talos Ocho will become operator of the Coulomb field.

“Talos Target Assets” means the undivided 50% interest in the PSA Assets to be acquired by our wholly owned subsidiary, Talos Ocho, pursuant to the Purchase Agreement, comprised of the Talos Target Coulomb Interest and the Talos Target Na Kika Interests.

“Talos Target Coulomb Interest” means the 50% working interest and operatorship in the Coulomb field to be acquired by our wholly owned subsidiary, Talos Ocho, pursuant to the Purchase Agreement.

“Talos Target Na Kika Interests” means the undivided 25% working interest in the Na Kika Interests to be acquired by our wholly owned subsidiary, Talos Ocho, pursuant to the Purchase Agreement.

Ongoing Acquisition and Investment Activities

Consistent with our business strategy, we regularly engage in the evaluation of potential acquisitions, investment opportunities, and capital projects. As a part of these efforts, we often engage in discussions with potential sellers, partners or other counterparties regarding the possible purchase of or investment in assets and operations that are strategic and complementary to our existing operations in accordance with our stated strategy to become a leading pure-play offshore E&P. Any such transactions in non-U.S. jurisdictions may be undertaken by one or more current or future foreign subsidiaries which are not, or will not be, guarantors under the Indenture.

We are currently focused on pursuing additional exploration and development opportunities that will further expand our deepwater scale in offshore Gulf of America, Gulf of Mexico, and conventional offshore basins with similar geologic characteristics. In particular, we are in current negotiations with a seller in connection with a potential long-term, non-operated opportunity. To the extent that an agreement with respect to the acquisition is reached, we would expect any initial capital outlay to be limited in nature. Talos’ share of capital expenditures as partner in the project would be expected to be weighted heavily towards the end of the decade, and would be expected to be in line with Talos’ long-term investment and capital allocation strategy. We would anticipate the funding of these investments to include a combination of cash generated from operations, cash on hand, borrowings under our Bank Credit Facility, and/or project financing.

The timeline required to negotiate and close on any one or more opportunities is at times unpredictable and can vary greatly. We typically do not announce a transaction until after we have executed a definitive agreement. In certain cases, in order to protect our business interests or for other reasons, we may defer public announcement of a transaction until closing or a later date. Past experience has demonstrated that discussions and negotiations regarding a potential transaction can advance or terminate in a short period of time. Moreover, the closing of any transaction for which we have entered into a definitive agreement may be subject to customary and other closing conditions, which may not ultimately be satisfied or waived. Such transactions may involve material investments and result in a reallocation of capital. Accordingly, we can give no assurance that our current or future acquisition or investment efforts will be successful.

Summary Historical and Pro Forma Reserve, Production and Operating Data

The following table presents our estimated proved oil, natural gas and NGLs reserves and the reserves associated with the Talos Target Coulomb Interest and the Talos Target Na Kika Interests as of December 31, 2025, individually and on a pro forma combined basis. The reserve estimates as of December 31, 2025 presented with respect to Talos were estimated by Netherland, Sewell & Associates, Inc. (“NSAI”) based on pricing guidelines established by the SEC (“SEC Pricing”). The reserve estimates as of December 31, 2025 presented with respect to the Talos Target Coulomb Interest and the Talos Target Na Kika Interests are based on separate reserve reports prepared by NSAI with respect to the Coulomb Interest and the Na Kika Interests, respectively, in each case based on SEC Pricing, and represent 50% of the reserve estimates with respect to the Coulomb Interest and the Na Kika Interests, as applicable, that were included in such reports. Unless otherwise indicated, the references to the estimated reserves in this section give pro forma effect to the Gulf of America Acquisition as it had been completed on December 31, 2025. The summary pro forma combined production data set forth below gives effect to the Gulf of America Acquisition as if it had been completed on January 1, 2025. The following summary pro forma combined reserve and production data have been prepared for illustrative purposes only and are not intended to be a projection of future results of the Company.

SEC Pricing adjusted by lease for market differentials (quality, transportation, fees, energy content and regional price differentials) as of December 31, 2025 for Talos was $65.37 per Bbl of oil, $3.61 per Mcf of natural gas and $19.22 per Bbl of NGLs. SEC Pricing adjusted by lease for market differentials as of December 31, 2025 for the Talos Target Assets was $64.41 per Bbl of oil and $4.18 per Mcf of natural gas.

PV-10 is a non-GAAP financial measure and differs from the standardized measure of discounted future net cash flows, which is the most directly comparable GAAP financial measure. PV-10 is a computation of the standardized measure of discounted future net cash flows on a pre-tax basis. PV-10 is equal to the standardized measure of discounted future net cash flows at the applicable date, before deducting future income taxes, discounted at 10%. We believe that the presentation of PV-10 is relevant and useful to investors because it presents the discounted future net cash flows attributable to our estimated net proved reserves prior to taking into account future corporate income taxes, and it is a useful measure for evaluating the relative monetary significance of our oil and natural gas properties. Further, investors may utilize the measure as a basis for comparison of the relative size and value of our reserves to other companies without regard to the specific tax characteristics of such entities. We use this measure when assessing the potential return on investment related to our oil and natural gas properties. PV-10, however, is not a substitute for the standardized measure of discounted future net cash flows. Our PV-10 measure and the standardized measure of discounted future net cash flows do not purport to represent the fair value of our oil and natural gas reserves.
