TALOS ENERGY INC.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

QuarterNorth Acquisition

On January 13, 2024, we entered into a definitive agreement to acquire QuarterNorth, a private operator in the Deepwater U.S. Gulf of Mexico, for consideration consisting of (i) $1,273.9 million in cash and (ii) 24.8 million shares of our common stock (the “QuarterNorth Acquisition,” and such agreement the “QuarterNorth Merger Agreement”). We expect to fund the cash portion of the purchase price for the QuarterNorth Acquisition via borrowings under the Talos Production bank credit facility (the “Bank Credit Facility”), the proceeds from an underwritten equity offering, available cash on hand and, opportunistically to the extent market conditions warrant, other capital markets offerings or other debt financings, as appropriate. The QuarterNorth Acquisition is expected to close in the first quarter of 2024, subject to customary closing conditions.

EnVen Acquisition

On February 13, 2023, we completed the acquisition (the “EnVen Acquisition”) of EnVen, a private operator in the Deepwater U.S. Gulf of Mexico, for consideration consisting of (i) $207.3 million in cash, (ii) 43.8 million shares of the Company’s common stock valued at $832.2 million and (iii) the effective settlement of an accounts receivable balance of $8.4 million.

Other Transaction Accounting Adjustments

The transaction accounting adjustments in the pro forma financial statements for the QuarterNorth Acquisition and EnVen Acquisition consists of those necessary to account for the transactions. Separately, we expect to generate gross proceeds of $300.0 million by issuing shares of our common stock in an underwritten equity offering to partially fund the cash consideration in the QuarterNorth Acquisition. The adjustments related to the issuance of common stock are shown in a separate column as “Equity Financing.”

Pro Forma Presentation

The following unaudited pro forma combined financial statements (which we refer to as the “pro forma financial statements”) have been prepared from the respective historical consolidated financial statements of Talos, EnVen, and QuarterNorth adjusted to give effect to the EnVen Acquisition and QuarterNorth Acquisition and related financing consisting of borrowings under the Bank Credit Facility and planned proceeds from the underwritten equity offering. The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2023, and the year ended December 31, 2022, combine the historical consolidated statement of operations of Talos, EnVen, and QuarterNorth, giving effect to the EnVen Acquisition and QuarterNorth Acquisition and related financing as if the transactions had been consummated on January 1, 2022. The unaudited pro forma condensed combined balance sheet combines the historical consolidated balance sheets of Talos and QuarterNorth as of September 30, 2023, giving effect to the QuarterNorth Acquisition and related financing as if the transactions had been consummated on September 30, 2023. The pro forma financial statements contain certain reclassification adjustments to conform the historical EnVen and QuarterNorth financial statement presentation to Talos’s financial statement presentation.

The pro forma financial statements are presented to reflect the EnVen Acquisition and QuarterNorth Acquisition and related financing and do not represent what Talos’s financial position or results of operations would have been had these acquisitions occurred on the dates noted above, nor do they project the financial position or results of operations of the combined company following these acquisitions. The pro forma financial statements are intended to provide information about the continuing impact of the acquisitions and related financing as if the transaction had been consummated earlier. The pro forma adjustments are based on available information and certain assumptions that management believes are factually supportable and are expected to have a continuing impact on Talos’s results of operations. In the opinion of management, all adjustments necessary to present fairly the pro forma financial statements have been made.

Talos used currently available information to determine preliminary fair value estimates for the consideration and its allocation to the QuarterNorth assets acquired and liabilities assumed. The estimates of fair value of QuarterNorth’s assets and liabilities are based on reviews of QuarterNorth’s internally generated financial statements and other due diligence procedures. The assumptions and estimates used to determine the preliminary purchase price allocation and fair value adjustments are described in the notes accompanying the pro forma financial statements.

2

The preliminary purchase price allocation is subject to change due to changes in the estimated fair value of QuarterNorth’s identifiable assets acquired and liabilities assumed as of the closing date, which could result from Talos’s additional valuation analysis, reserves estimates, discount rates and other factors.

As a result of the foregoing, the pro forma adjustments are preliminary and subject to change as additional information becomes available and additional analysis is performed. The preliminary pro forma adjustments have been made solely for the purpose of providing the pro forma financial statements presented below. Any increases or decreases in the fair value of assets acquired and liabilities assumed upon completion of the final valuation will result in adjustments to the pro forma balance sheet and if applicable, the pro forma statement of operations. The final purchase price allocation may be materially different than that reflected in the preliminary purchase price allocation presented herein.

The pro forma financial statements have been developed from and should be read in conjunction with the separate historical consolidated financial statements and related notes thereto in Talos’s SEC filings, EnVen’s historical consolidated financial statements and related notes thereto included in the April 12, 2023 current report on Form 8-K, and QuarterNorth’s historical consolidated financial statements and related notes thereto included in this current report on Form 8-K.

Talos historical general and administrative (“G&A”) expense above includes approximately $9.0 million of nonrecurring acquisition-related costs in connection with the EnVen Acquisition. EnVen historical G&A expense above includes $7.3 million of nonrecurring transaction costs associated with the EnVen merger with Talos.

The following adjustments and assumptions were made in the preparation of the unaudited pro forma financial statements:

(a) Reflects reclassifications to the EnVen historical financial statements to conform to Talos’ financial statement presentation.

(b) Reflects changes in depletion that would have been recorded with respect to the allocated fair values attributable to proved oil and natural gas properties acquired as a result of the application of the full cost method of accounting for oil and natural gas activities following the EnVen Acquisition. The pro forma depletion rate for the year ended December 31, 2022 was estimated using the proved property amounts based on the preliminary purchase price allocation and estimates of reserves at December 31, 2022, adjusted for actual production. The pro forma depletion rates were applied to production volumes for the Talos properties and EnVen properties for the respective period. Depreciation, depletion and amortization increased by $132.5 million for the year ended December 31, 2022 and $3.9 for the period from January 1, 2023 to February 12, 2023.

(c) Reflects changes in accretion expense that would have been recorded with respect to the allocated fair values attributable to asset retirement obligations assumed with a decrease to accretion expense of $3.3 million for the year ended December 31, 2022 and a decrease to accretion expense of $0.6 million for the period from January 1, 2023 to February 12, 2023.

10

(d) Reflects amortization of the premium associated with senior notes assumed as a reduction to interest expense of $2.6 million for the year ended December 31, 2022 and $0.2 for the period from January 1, 2023 to February 12, 2023.

(e) Reflects an increase in interest expense assuming additional borrowings of $163.2 million under the Bank Credit Facility to fund a portion of the cash consideration. For the year ended December 31, 2022, pro forma interest expense was based on a weighted-average interest rate of 5.47%. For the period from January 1, 2023 to February 12, 2023, pro forma interest expense was based on a weighted-average interest rate of 7.94%. The table below represents the effects of a one-eighth percentage point change in the interest rate on the pro forma interest associated with the additional borrowings (dollars in thousands):

		Nine Months Ended September 30, 2023				Year Ended December 31, 2022
Weighted-average interest rate			7.94	%			5.47	%
Interest expense		$	1,526			$	8,929
Weighted-average interest rate—increase 0.125%			8.07	%			5.60	%
Interest expense		$	1,550			$	9,133
Weighted-average interest rate—decrease 0.125%			7.82	%			5.35	%
Interest expense		$	1,502			$	8,725

(f) Reflects accretion of the discount as an increase to interest expense of $0.4 million and less than $0.1 million for the year ended December 31, 2022 and period from January 1, 2023 to February 12, 2023, respectively, associated with a consent solicitation fee of $3.1 million related to Talos Production’s senior notes.

(g) Reflects accretion of discount as an increase to other income (expense) of $1.5 million and $0.1 million for the year ended December 31, 2022 and period from January 1, 2023 to February 12, 2023, respectively, associated with acquired notes receivable.

(h) Reflects the income tax effect of the transaction accounting adjustments presented using the statutory tax rate in effect during the period. Because the tax rates used for these unaudited pro forma condensed combined statement of operations are an estimate, the blended rate will vary from the actual effective rate in periods subsequent to completion of the EnVen Acquisition.

(i) Reflects the increase in shares of Talos common stock resulting from the issuance of shares of Talos common stock to EnVen stockholders to effect the EnVen Acquisition.

Note 3—QuarterNorth Preliminary Acquisition Accounting

Talos has determined it is the accounting acquirer for the QuarterNorth Acquisition which will be accounted for under the acquisition method of accounting for business combinations in accordance with Accounting Standards Codification 805, Business Combinations (“ASC 805”). The allocation of the preliminary estimated purchase price with respect to the QuarterNorth Acquisition is based upon management’s estimates of and assumptions related to the fair values of assets to be acquired and liabilities to be assumed as of September 30, 2023 using currently available information. Due to the fact that the unaudited pro forma combined financial statements have been prepared based on these preliminary estimates, the final purchase price allocation and the resulting effect on Talos’s financial position and results of operations may differ significantly from the pro forma amounts included herein.

The final purchase price allocation for the business combination will be performed subsequent to closing and adjustments to estimated amounts or recognition of additional assets acquired or liabilities assumed may occur as more detailed analyses are completed and additional information is obtained about the facts and circumstances that existed as of the closing date of the QuarterNorth Acquisition. Talos expects to finalize the purchase price allocation as soon as practicable after completing the QuarterNorth Acquisition.

The preliminary purchase price allocation is subject to change due to changes in the estimated fair value of QuarterNorth’s identifiable assets acquired and liabilities assumed as of the closing date of the QuarterNorth Acquisition, which could result from Talos’s additional valuation analysis, reserves estimates, discount rates and other factors.

Note 4—QuarterNorth Transaction Accounting Adjustments

The following adjustments and assumptions were made in the preparation of the unaudited pro forma financial statements:

(a) Reflects reclassifications to the QuarterNorth historical financial statements to conform to Talos’s financial statement presentation.

(b) Reflects an increase of $584.7 million in long-term debt and associated interest expense attributable to additional borrowings under the Bank Credit Facility to fund a portion of the cash consideration. The increase in interest expense assumes the borrowing occurred on January 1, 2022 and was outstanding for both the year ended December 31, 2022 and nine months ended September 30, 2023. For the year ended December 31, 2022 and nine months ended September 30, 2023, pro forma interest expense was based on a weighted-average interest rate of 5.47% and 8.10%, respectively. The table below represents the effects of a one-eighth percentage point change in the interest rate on the pro forma interest associated with the additional borrowings (dollars in thousands):

		Nine Months Ended September 30, 2023				Year Ended December 31, 2022
Weighted-average interest rate			8.10	%			5.47	%
Interest expense		$	35,507			$	31,998
Weighted-average interest rate—increase 0.125%			8.22	%			5.60	%
Interest expense		$	36,055			$	32,729
Weighted-average interest rate—decrease 0.125%			7.97	%			5.35	%
Interest expense		$	34,958			$	31,267

(c) Reflects the accrual for transaction costs of $14.6 million related to the QuarterNorth Acquisition including, among others, fees paid for financial advisors, legal services and professional accounting services. The costs are not reflected in the historical September 30, 2023 consolidated balance sheet of Talos, but are reflected in the Talos combined pro forma balance sheet as of September 30, 2023, as an increase to Accrued liabilities and increase to Accumulated deficit. The Talos combined pro forma statement of operations for the year ended December 31, 2022, reflects a $14.6 million expense to General and administrative expense as the transaction costs will be expensed by Talos as incurred. These amounts and their corresponding tax effect have not been reflected in the pro forma statement of operations for the nine months ended September 30, 2023, due to their nonrecurring nature. These costs are not expected to be incurred in any period beyond 12 months from the closing date of the QuarterNorth Acquisition.

(d) Reflects the cash consideration paid to QuarterNorth stockholders to effect the QuarterNorth Acquisition.

(e) Reflects the increase in shares of Talos common stock and additional paid-in capital in excess of par resulting from the issuance of shares of Talos common stock to QuarterNorth stockholders to effect the QuarterNorth Acquisition based on the Talos closing share price of $13.51 on January 12, 2024.

(f) Reflects the elimination of QuarterNorth’s historical equity balances in accordance with the acquisition method of accounting.

(g) Reflect the income tax effects of the transaction accounting adjustments presented using the statutory tax rate in effect during the period. Because the tax rates used for these unaudited pro forma condensed combined statement of operations are an estimate, the blended rate will vary from the actual effective rate in periods subsequent to completion of the QuarterNorth Acquisition.

(h) Reflects the write-off of QuarterNorth’s historical unamortized and deferred financing costs.

13

(i) Reflects the adjustments to reflect the preliminary estimated fair value of Talos common stock of $335.0 million and cash consideration of $1,273.9 million allocated to the estimated fair values of the assets acquired and liabilities assumed.

Reflects a $663.5 million increase to Total Property and Equipment, net calculated as the difference between the estimated fair value and QuarterNorth’s historical net book value. The change is primarily a result of (i) a decrease in Proved properties as a result of QuarterNorths’s partial depletion of proved oil and natural gas reserves which is presented in Accumulated depreciation, depletion and amortization offset by the increase in estimated fair value of the remaining proved reserves over historical cost, (ii) increase in Unproved properties, not subject to amortization due to higher fair values of properties compared to historical value and (iii) the elimination of the historical QuarterNorth Accumulated depreciation, depletion and amortization. The fair value of oil and natural gas properties were measured using a discounted cash flow technique of valuation. Inputs to the valuation of oil and natural gas properties include estimates of: (i) reserves, (ii) future operating and development costs, (iii) future commodity prices, (iv) future plugging and abandonment costs, (v) estimated cash flows and (vi) a market-based weighted average cost of capital rate. These estimates require significant judgment and may vary due to many factors, such as, but not limited to, the inputs to the fair value measure described above.

(j) Reflects changes in depletion that would have been recorded with respect to the allocated fair values attributable to proved oil and natural gas properties acquired as a result of the application of the full cost method of accounting for oil and natural gas activities following the QuarterNorth Acquisition. The pro forma depletion rate for the year ended December 31, 2022 was estimated using the proved property amounts based on the preliminary purchase price allocation and estimates of reserves at December 31, 2022, adjusted for actual production. The pro forma depletion rate for the nine months ended September 30, 2023 was estimated using the proved property amounts based on the preliminary purchase price allocation and estimates of reserves at September 30, 2023, adjusted for actual production. The pro forma depletion rates were applied to production volumes for the Talos properties, the EnVen properties and QuarterNorth properties for the respective periods. Depreciation, depletion and amortization decreased by $2.5 million for the year ended December 31, 2022 and $0.4 million for the nine months ended September 30, 2023.

(k) Reflects purchase accounting adjustment to the Historical QuarterNorth Deferred tax liability of $68.0 million to record the estimated deferred income tax effects of $144.0 million to reflect the QuarterNorth Acquisition. Because the tax rates used for these unaudited pro forma condensed balance sheet are an estimate, the blended rate will vary from the actual effective rate in periods subsequent to completion of the QuarterNorth Acquisition.

(l) Reflects the elimination of revenues and costs of good sold associated with the disposition of QuarterNorth’s decommissioning services business under turnkey agreements. The revenues and costs are not expected to be incurred in any period beyond 12 months from the closing date of the QuarterNorth Acquisition.

(m) In the event that additional financing is needed to fund the cash consideration for the QuarterNorth Acquisition, we received a $650.0 million commitment under a bridge credit facility from a syndicate of lenders, including some lenders under our Bank Credit Facility. For pro forma purposes, the bridge loan was unused and the adjustment reflects the amortization of debt issuance costs associated with the unused bridge facility. If the bridge loan were fully utilized to partially fund the cash consideration for the QuarterNorth Acquisition, the incremental interest expense in the pro forma financial statements would be $59.2 million and $37.5 million for the year ended December 31, 2022 and nine months ended September 30, 2023, respectively.

(n) Reflects the accrual of contractual severance and other separation benefits associated with existing QuarterNorth employment agreements in connection with the termination of certain executive officers of QuarterNorth that will occur immediately after the consummation of the QuarterNorth Acquisition. The post-combination expense is reflected in the Talos combined pro forma balance sheet as of September 30, 2023, as an increase to Accrued liabilities and to Accumulated deficit, and in the Talos combined pro forma statement of operations for the year ended December 31, 2022, within General and administrative expense.

Note 5—Equity Financing

We expect to generate gross proceeds of $300.0 million (before underwriting discounts and commissions and offering expenses) in an underwritten offering of our common stock to partially fund the cash consideration in the QuarterNorth Acquisition. After deducting the underwriting discounts and commissions and offering expenses payable by us, the total net proceeds are expected to be approximately $287.8 million. Based on the closing price of Talos common stock on January 12, 2024 of $13.51, we expect to issue approximately 22.2 million shares of common stock (assuming no exercise of underwriters’ option to purchase additional shares). The following table summarizes the estimated common stock to be issued resulting from a 10% fluctuation in the market price of Talos common stock (in thousands, except per share amounts):

		Talos share price				Common stock issued
As presented		$	13.51				22,206
10% increase			14.86				20,187
10% decrease			12.16				24,673

The following table presents the estimated pro forma discounted future net cash flows at December 31, 2022. The pro forma standardized measure information set forth below gives effect to the EnVen Acquisition and QuarterNorth Acquisition as if these acquisitions had been completed on January 1, 2022. The disclosures below were determined by referencing the “Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil, Natural Gas and NGL Reserves” reported in Talos’s Annual Report on Form 10-K for the year ended December 31, 2022, the “Standardized Measure of Discounted Future Net Cash Flows” reported in EnVen’s Annual Report for the year ended December 31, 2022 and the “Standardized Measure of Discounted Future Net Cash Flows” reported in QuarterNorth’s Annual Report for the year ended December 31, 2022. An explanation of the underlying methodology applied, as required by SEC regulations, can be found within the Talos Annual Report on Form 10-K, EnVen Annual Report and QuarterNorth Annual Report. The calculations assume the continuation of existing economic, operating and contractual conditions at December 31, 2022.

Therefore, the following estimated pro forma standardized measure is not necessarily indicative of the results that might have occurred had these acquisitions been completed on January 1, 2022 and is not intended to be a projection of future results.
