Notes to Consolidated Financial Statements

(Unaudited)

1. Organization

Kosmos Energy Ltd. is incorporated in the State of Delaware as a holding company for Kosmos Energy Delaware Holdings, LLC, a Delaware limited liability company. As a holding company, Kosmos Energy Ltd.’s management operations are conducted through a wholly-owned subsidiary, Kosmos Energy, LLC. The terms “Kosmos,” the “Company,” “we,” “us,” “our,” “ours,” and similar terms refer to Kosmos Energy Ltd. and its wholly-owned subsidiaries, unless the context indicates otherwise.

Kosmos Energy is a leading deepwater exploration and production company focused on meeting the world’s growing demand for energy. We have diversified oil and gas production from assets offshore Ghana, Equatorial Guinea, Mauritania, Senegal and the Gulf of America. Additionally, in the proven basins where we operate we are advancing high-quality development opportunities, which have come from our exploration success. Kosmos is listed on the NYSE and LSE and is traded under the ticker symbol KOS.

Kosmos is engaged in a single line of business, which is the exploration, development, and production of oil and natural gas. Substantially all of our long-lived assets and all of our product sales are related to operations in four geographic areas: Ghana, Equatorial Guinea, Mauritania/Senegal and the Gulf of America.

2. Accounting Policies

General

The interim consolidated financial statements included in this report are unaudited and, in the opinion of management, include all adjustments of a normal recurring nature necessary for a fair presentation of the results for the interim periods. The results of the interim periods shown in this report are not necessarily indicative of the final results to be expected for the full year. The interim consolidated financial statements were prepared in accordance with the requirements of the SEC for interim reporting. As permitted under those rules, certain notes or other financial information that are normally required by GAAP have been condensed or omitted from these interim consolidated financial statements. These interim consolidated financial statements and the accompanying notes should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2025, included in our annual report on Form 10-K.

Reclassifications

Certain prior period amounts have been reclassified to conform with the current presentation. Such reclassifications had no significant impact on our reported net loss, current assets, total assets, current liabilities, total liabilities, stockholders’ equity or cash flows.

Cash, Cash Equivalents and Restricted Cash


	March 31, 2026		December 31, 2025
	(In thousands)
Cash and cash equivalents	$	129,957	$	91,518
Cash included in assets held for sale	7,960		—

Restricted cash - long-term	30,630		26,226
Total cash, cash equivalents and restricted cash in the consolidated statements of cash flows	$	168,547	$	117,744

Cash and cash equivalents include demand deposits and funds invested in highly liquid instruments with original maturities of three months or less at the date of purchase. Restricted cash – long-term primarily represents cash and cash equivalents collateralized, in accounts held by us, as required to support existing performance obligations in the GoA. When our debt cover ratio exceeds 2.50x, we are required under the Facility to maintain a restricted cash balance that is sufficient to meet the payment of interest and fees for the next six-month period on the 7.750% Senior Notes, the 7.500% Senior Notes, the

Table of Contents

8.750% Senior Notes and the 3.125% Convertible Senior Notes or the Facility, whichever is greater. During the first quarter of 2025, the Facility lenders waived the requirement to maintain a restricted cash balance until the March 31, 2026 financial covenant test date. Our debt cover ratio for the most recent March 31, 2026 financial covenant test date exceeded 2.50x and the estimated restricted cash funding requirement is approximately $47.0 million. We are currently in discussions with the Facility lenders seeking approval to extend the prior waiver, but if no approval is granted then we plan to start funding the debt service reserve account in the second quarter, as required under the terms of the Facility.

Joint Interest Billings

The Company’s joint interest billings consist of receivables from partners with interests in common oil and natural gas properties operated by the Company for shared costs. Joint interest billings are classified on the face of the consolidated balance sheets as current and long-term receivables based on when collection is expected to occur.

Inventories

Inventories consisted of $144.0 million and $144.9 million of materials and supplies and $38.7 million and $27.7 million of hydrocarbons as of March 31, 2026 and December 31, 2025, respectively. The Company’s materials and supplies inventory primarily consists of casing and wellheads and is stated at the lower of cost, using the weighted average cost method, or net realizable value.

Hydrocarbon inventory is carried at the lower of cost, using the weighted average cost method, or net realizable value. Hydrocarbon inventory costs include expenditures and other charges incurred in bringing the inventory to its existing condition. Selling expenses and general and administrative expenses are reported as period costs and excluded from inventory costs.

Assets and Liabilities Held for Sale

The Company classifies disposal groups as held for sale in the period in which all of the following criteria are met: (1) management, having the authority to approve the action, commits to a plan to sell the disposal group; (2) the disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such disposal groups; (3) an active program to locate a buyer or buyers and other actions required to complete the plan to sell the disposal group have been initiated; (4) the sale of the disposal group is probable, and the transfer of the disposal group is expected to qualify for recognition as a completed sale, within one year, except if events or circumstances beyond the Company’s control extended the period of time required to sell the disposal group beyond one year; (5) the disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and (6) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn.

A disposal group that is classified as held for sale is initially measured at the lower of its carrying amount or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Subsequent changes in fair value of a disposal group less any costs to sell are reported as an adjustment to the carrying amount of the disposal group, as long as the new carrying amount does not exceed the carrying amount of the assets at the time it was initially classified as held for sale. Depreciation, depletion and amortization expense is not recorded on assets to be divested once they are classified as held for sale. In the initial period in which the disposal group meets the criteria to be classified as held for sale, the assets and liabilities of the disposal group are separately presented as assets held for sale and liabilities held for sale, respectively, in the Consolidated Balance Sheets.

Revenue Recognition

Our oil and gas revenues are recognized when hydrocarbons have been sold to a purchaser at a fixed or determinable price, title has transferred and collection is probable. Certain revenues are based on contracts with provisional pricing and quantity optionality which contain a derivative that is separated from the host contract for accounting purposes. The host contract is the receivable from sales at the spot price on the date of sale. The derivative, which is not designated as a hedge, is marked to market through oil and gas revenue each period until the final settlement occurs, which generally is limited to the month of or month after the sale.

Table of Contents

Oil and gas revenue is composed of the following:


	Three Months Ended March 31,
	2026		2025
	(In thousands)
Revenues from contracts with customers:
Ghana	$	250,152	$	152,805

Provisional sales contracts	(50,980)		(827)
Oil and gas revenue	$	370,728	$	290,135

Concentration of Credit Risk

Our revenue can be materially affected by current economic conditions and the price of oil and natural gas. However, based on the current demand for crude oil and natural gas and the fact that alternative purchasers are readily available, we believe that the loss of our purchasers and/or of the purchasers identified by our marketing agents would not have a long‑term material adverse effect on our financial position or results of Ghana and Equatorial Guinea operations. Customers in our Gulf of America and Mauritania | Senegal business units that comprise 10% or more of our total consolidated oil and gas revenue for the three months ended March 31, 2026 and 2025, are shown below.

Recent Accounting Standards

Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”. The amendments in ASU 2024-03 require more detailed disclosures about specified categories of costs and expenses included in certain expense captions presented on the face of the income statement. This ASU is effective for fiscal years beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is currently assessing the impact of this standard on its financial statement disclosures.

In November 2024, the FASB issued ASU 2024-04, “Debt - Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments.” The amendments in ASU 2024-04 clarify the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion. The amendments in the ASU are effective for annual periods beginning after December 15, 2025. Early adoption is permitted, however, we do not plan to early adopt ASU 2024-04. The Company is currently assessing the impact this standard will have on its consolidated financial statements.

3. Acquisitions and Divestitures

Table of Contents

Management considers the assets and liabilities in the Ceiba Field and Okume Complex production assets located in Block G offshore Equatorial Guinea included in the Share Sale and Purchase Agreement as a disposal group. As of March 31, 2026, the assets and liabilities of the disposal group were classified as held for sale. The expected cash consideration of $180.0 million, subject to certain adjustments, and future contingent consideration of up to $39.5 million per the Share Sale and Purchase Agreement exceeds the carrying value of the disposal group, and thus, no adjustment to the carrying value of the disposal group was necessary. Upon classification of the disposal group as held for sale, the Company ceased recording depletion expense for long-lived assets of the disposal group. The divestiture does not meet the criteria to be reported as discontinued operations as it did not represent a strategic shift for the Company. Therefore, the Company continued to report operating results for the assets held for sale in the Company’s Consolidated Statement of Operations.

The following is a summary of the carrying amounts of the major classes of assets and liabilities that were classified as held for sale:

The Company’s joint interest billings consist of receivables from partners with interests in common oil and gas properties operated by the Company for shared costs. Joint interest billings are classified as current and long-term receivables based on when collection is expected to occur.

Long-term receivables

In February 2019, Kosmos and BP signed Carry Advance Agreements with the national oil companies of Mauritania and Senegal obligating us to finance a portion of the respective national oil company’s share of certain development and production costs incurred for the GTA Phase 1 project through the Commercial Operations Date of the Gimi FLNG vessel. The Commercial Operations Date of the Gimi FLNG vessel was achieved in June 2025. As of March 31, 2026 and December 31, 2025, the balance due from the national oil companies including accrued interest was $443.9 million and $437.1 million, respectively, which is classified as Long-term receivables in our consolidated balance sheets. Interest income on the long-term notes receivable was $6.8 million and $5.4 million for the three months ended March 31, 2026 and 2025, respectively.

We recorded depletion expense of $111.6 million and $111.3 million for the three months ended March 31, 2026 and 2025, respectively. During the three months ended March 31, 2026, the decrease in oil and gas properties is primarily due to oil and gas properties in the Ceiba and Okume Complex production assets located in Block G offshore Equatorial Guinea that are classified as held for sale. See Note 3 - Acquisitions and Divestitures. Additions to our proved properties during the three months ended March 31, 2026 primarily related to infill development costs in the Jubilee Field in Ghana. Additionally, in February 2026, Tullow Oil plc, as Operator of the TEN partnership, executed the final Sale and Purchase Agreement enabling the partnership to acquire the TEN FPSO from MODEC, Inc. at the end of its current lease in 2027 for a gross purchase price of $205.0 million. As a result, Kosmos recognized non-cash proved property additions of $85.4 million for our proportionate share of the finance lease asset with a corresponding finance lease liability in accrued liabilities. These non-cash impacts are excluded from the statement of cash flows.

As of March 31, 2026, the projects with exploratory well costs capitalized for more than one year since the completion of drilling are related to the Tiberius discovery in Keathley Canyon Block 964 in the Outer Wilcox play in the Gulf of America.

Tiberius Discovery — In July 2023, we spud the Tiberius infrastructure-led exploration prospect located in Block 964 of Keathley Canyon in the Gulf of America, which encountered hydrocarbon pay. Initial fluid and core analysis supports the production potential of the well, with characteristics analogous with similar nearby discoveries in the Wilcox trend. In March 2024, we completed the acquisition of an additional 16.7% participating interest in the Keathley Canyon Blocks 920 and 964, offshore Gulf of America. As a result of the transaction, Kosmos’ participating interest in the Tiberius discovery area increased from 33.3% to 50.0%. The Tiberius project is being progressed as a phased development with a final investment decision for the development achieved in March 2026.

Facility

The Facility supports our oil and gas exploration, appraisal and development programs and corporate activities. The amount of funds available to be borrowed under the Facility, also known as the borrowing base amount, is determined every March and September. In April 2026, during the Spring 2026 redetermination, the Company’s lending syndicate approved a borrowing base at approximately $1.25 billion. The borrowing base amount is based on the sum of the net present values of net cash flows and relevant capital expenditures reduced by certain percentages as well as value attributable to certain assets’ reserves and/or resources in the Company’s production assets in Ghana and Equatorial Guinea. Following closing of the sale of all our participating interest in the Ceiba Field and Okume Complex production assets located in Block G offshore Equatorial Guinea, the Company’s production assets in Equatorial Guinea will no longer be included in the borrowing base amount, and we have agreed with the lending syndicate to further reduce the borrowing base to approximately $1.2 billion. As of March 31, 2026, borrowings under the Facility totaled approximately $1.0 billion and the undrawn availability under the Facility was $350.0 million. Final maturity of the Facility is December 31, 2029.

Interest on the Facility is the aggregate of the applicable margin (4.00% to 5.50%, depending on the length of time that has passed from the date the Facility was entered into), plus the term SOFR reference rate administered by CME Group Benchmark Administration Limited for the relevant period published. Interest is payable on the last day of each interest period (and, if the interest period is longer than six months, on the dates falling at six-month intervals after the first day of the interest period). We pay commitment fees on the undrawn and unavailable portion of the total commitments, if any. Commitment fees are equal to 30% per annum of the then-applicable respective margin when a commitment is available for utilization and, equal to 20% per annum of the then-applicable respective margin when a commitment is not available for utilization. We recognize interest expense in accordance with ASC 835 — Interest, which requires interest expense to be recognized using the effective interest method. We determined the effective interest rate based on the estimated level of borrowings under the Facility.

The Facility provides a revolving credit and letter of credit facility. As of March 31, 2026, we had no letters of credit issued under the Facility.

When our debt cover ratio exceeds 2.50x, we are required under the Facility to maintain a restricted cash balance that is sufficient to meet the payment of interest and fees for the next six-month period on the 7.750% Senior Notes, the 7.500% Senior Notes, the 8.750% Senior Notes and the 3.125% Convertible Senior Notes or the Facility, whichever is greater. During the first quarter of 2025, the Facility lenders waived the requirement to maintain a restricted cash balance until the financial covenant test date to be calculated on March 31, 2026. Our debt cover ratio for the most recent March 31, 2026 financial covenant test date exceeded 2.50x and the estimated restricted cash funding requirement is approximately $47.0 million. We are

Table of Contents

currently in discussions with the Facility lenders seeking approval to extend the prior waiver, but if no approval is granted then we plan to start funding the debt service reserve account in the second quarter, as required under the terms of the Facility.

In July 2025, the Company and the Facility lenders agreed to amend the debt cover ratio required under the Facility. The amendment made this covenant less restrictive for the following two scheduled financial covenant assessment dates, up to a maximum of 4.0x and 4.25x, respectively, and thereafter returned to the originally agreed upon ratio of 3.50x for assessment dates thereafter. In February 2026, we further amended the debt cover ratio calculation through September 2026. This most recent amendment makes the covenant less restrictive for the following two scheduled financial covenant assessment dates, up to a maximum of 4.5x and 4.25x respectively, and for purposes of the financial covenant assessment date in March 2026, the calculation was made excluding the Company’s Mauritania and Senegal business unit. The debt cover ratio returns to the originally agreed upon ratio of 3.5x for assessment dates thereafter. The change was intended to align the covenant calculation with recent business operations, lower oil prices and the impact of operating costs during the ramp-up of the GTA Phase 1 project on our results of operations.

We were in compliance with the financial covenants, as amended, contained in the Facility as of the most recent assessment date. The Facility contains customary cross default provisions.

In March 2024, the Company issued $400.0 million of 3.125% Convertible Senior Notes (the “3.125% Convertible Senior Notes”) and received net proceeds of $390.4 million after deducting fees. The 3.125% Convertible Senior Notes mature on March 15, 2030, unless earlier converted, redeemed or repurchased.

The 3.125% Convertible Senior Notes are guaranteed on a subordinated, unsecured basis by certain of our existing subsidiaries that borrow under or guarantee the Facility and guarantee on a subordinated basis the 7.750% Senior Notes, the 7.500% Senior Notes and the 8.750% Senior Notes, and, in certain circumstances, certain of our other existing or future subsidiaries.

The 3.125% Convertible Senior Notes indenture contains customary terms and covenants and cross default provisions.

The Company recorded the 3.125% Convertible Senior Notes, including the debt itself and all embedded derivatives, at cost less debt issuance costs of $9.6 million and has presented the 3.125% Convertible Senior Notes as a single financial instrument in Long-term debt, net in our consolidated balance sheet. No portion of the embedded derivatives required bifurcation from the host debt contract. As of March 31, 2026, the effective annual interest rate on the 3.125% Convertible Senior Notes is approximately 3.70%, including amortization of debt issuance costs.

The conversion rate for the 3.125% Convertible Senior Notes is initially 142.4501 shares of our common stock per $1,000 principal amount of 3.125% Convertible Senior Notes (which is the equivalent to an initial conversion price of approximately $7.02 per share of our common stock), subject to adjustments. As of March 31, 2026, no shares have been converted.

Capped Call Transactions

In connection with the issuance of the 3.125% Convertible Senior Notes, the Company used $49.8 million of the net proceeds from the issuance of the 3.125% Convertible Senior Notes to enter into capped call transactions (the “Capped Call Transactions”). The Capped Call Transactions are generally expected to reduce potential dilution to holders of our common stock upon any conversion of the 3.125% Convertible Senior Notes and/or offset any cash payments that we are required to make in excess of the principal amount of any 3.125% Convertible Senior Notes that are converted, as the case may be, with such reduction and/or offset subject to a cap.

The Capped Call Transactions qualify for a derivative scope exception as they are indexed to our common stock and are not required to be accounted for as a separate derivative. Consequently, the Capped Call Transactions have been included as a net reduction to additional-paid-in-capital within stockholders’ equity in our consolidated balance sheet and do not require subsequent remeasurement.

GoA Term Loan Facility

Table of Contents

The net proceeds were used, together with cash on hand, to fund the redemption of $250.0 million in aggregate of the 7.125% Senior Notes due 2026. On March 24, 2026, we made a voluntary prepayment of $53.6 million against the GoA Term Loan. On May 1, 2026, the GoA Term Loan Facility was amended to apply this prepayment in full satisfaction of the scheduled principal amount due on the first scheduled amortization payment date on June 30, 2026, and then ratably to all remaining scheduled principal payments of the outstanding loans. The amendment also deferred all future scheduled amortization payment dates in 2026, 2027 and 2028 such that they will now be due on October 1, January 1, April 1 and July 1 in each of 2026, 2027 and 2028. As a result of the amendment, there is only one remaining scheduled amortization payment in 2026 to be paid on October 1, 2026.

Interest on outstanding loans under the GoA Term Loan Facility is payable quarterly in arrears at a rate per annum equal to 3.75% plus the term SOFR reference rate administered by CME Group Benchmark Administration Limited for the relevant period published. The GoA Term Loan Facility matures in 2029, with principal payments beginning June 30, 2026.

The GoA Term Loan Facility contains customary affirmative and negative covenants, including covenants that affect our ability to incur additional indebtedness, create liens, merge, dispose of assets, and make distributions, dividends, investments or capital expenditures, among other things. The GoA Term Loan Facility requires the Company to maintain certain financial covenants including:

•the GoA field life coverage ratio (as defined in the glossary), not less than 1.50x; and

•the GoA net leverage ratio (as defined in the glossary), not more than 3.50x.

The GoA Term Loan Facility also includes certain representations and warranties, indemnities and events of default that, subject to materiality thresholds and grace periods, arise as a result of a payment of default, failure to comply with covenants, material inaccuracy of representation or warranty, and certain bankruptcy or insolvency proceedings. If there is an event of default, all or any portion of the outstanding indebtedness may be immediately due and payable and other rights may be exercised including against the collateral. We were in compliance with the covenants, representations and warranties contained in the GoA Term Loan Facility as of the most recent assessment date.

GTA Nordic bonds

In January 2026 the Company issued $350.0 million of 11.250% senior secured bonds due 2031 in the Nordic market (the “GTA Nordic bonds”). In the first quarter of 2026, the Company used the net proceeds from the Nordic bond offering to fund the repurchase of an aggregate principal amount of $249.8 million of the 7.750% Senior Notes pursuant to the Company’s cash tender offer announced on January 12, 2026 and open market repurchases, and to make a voluntary early principal repayment of $100.0 million on outstanding borrowings under the Facility.

The GTA Nordic bonds mature in January 2031. Interest is payable semi-annually in arrears each July 29 and January 29, commencing on July 29, 2026.

The GTA Nordic bonds are also guaranteed on an unsecured basis by certain of the Company’s subsidiaries that also guarantee the Company’s existing senior unsecured notes.

At any time prior to July 29, 2028, the Company may, on any one or more occasions, redeem all or part of the GTA Nordic bonds at a redemption price equal to 100%, plus any accrued and unpaid interest, and plus a “make-whole” premium.

If more than 90% of the outstanding GTA Nordic bonds have been repurchased as a result of the exercise of the Put Option, the Company will be entitled to repurchase all the remaining GTA Nordic bonds at a price equal to 101% of the principal amount.

The Bond Terms governing the GTA Nordic bonds restrict the ability of Kosmos Energy GTA Holdings, Kosmos Energy Tortue Finance, Kosmos Energy Senegal, Kosmos Energy Investments Senegal Limited and Kosmos Energy Mauritania to, among other things: incur or guarantee additional indebtedness, create liens, sell assets, enter into transactions with affiliates, or effect certain consolidations, mergers or amalgamations.

9. Derivative Financial Instruments

We use financial derivative contracts to manage exposures to commodity price and interest rate fluctuations. We do not hold or issue derivative financial instruments for trading purposes.

We manage market and counterparty credit risk in accordance with our policies and guidelines. In accordance with these policies and guidelines, our management determines the appropriate timing and extent of derivative transactions. We have included an estimate of non-performance risk in the fair value measurement of our derivative contracts as required by ASC 820 — Fair Value Measurement.

Offsetting of Derivative Assets and Derivative Liabilities

Our derivative instruments which are subject to master netting arrangements with our counterparties only have the right of offset when there is an event of default. As of March 31, 2026 and December 31, 2025, there was not an event of default and, therefore, the associated gross asset or gross liability amounts related to these arrangements are presented on the consolidated balance sheets.

10. Fair Value Measurements

In accordance with ASC 820 — Fair Value Measurement, fair value measurements are based upon inputs that market participants use in pricing an asset or liability, which are classified into two categories: observable inputs and unobservable inputs. Observable inputs represent market data obtained from independent sources, whereas unobservable inputs reflect a company’s own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. We prioritize the inputs used in measuring fair value into the following fair value hierarchy:

•Level 1 — quoted prices for identical assets or liabilities in active markets.

•Level 2 — quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs derived principally from or corroborated by observable market data by correlation or other means.

•Level 3 — unobservable inputs for the asset or liability. The fair value input hierarchy level to which an asset or liability measurement in its entirety falls is determined based on the lowest level input that is significant to the measurement in its entirety.

The following tables present the Company’s assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2026 and December 31, 2025, for each fair value hierarchy level:


	Fair Value Measurements Using:
	Quoted Prices in

The book values of cash and cash equivalents and restricted cash approximate fair value based on Level 1 inputs. Joint interest billings, oil and gas sales and other receivables, and accounts payable and accrued liabilities approximate fair value due to the short-term nature of these instruments. Our long-term receivables, after any allowances for credit losses, and other long-term assets approximate fair value. The estimates of fair value of these items are based on Level 2 inputs.

Table of Contents

Commodity Derivatives

Our commodity derivatives represent swaps, crude oil collars, put options and call options for notional barrels of oil at fixed Dated Brent and NYMEX WTI oil prices. The values attributable to our oil derivatives are based on (i) the contracted notional volumes, (ii) independent active futures price quotes for the respective index, (iii) a credit-adjusted yield curve applicable to each counterparty by reference to the credit default swap (“CDS”) market and (iv) an independently sourced estimate of volatility for the respective index. The volatility estimate was provided by certain independent brokers who are active in buying and selling oil options and was corroborated by market-quoted volatility factors. The deferred premium is included in the fair market value of the commodity derivatives. See Note 9 — Derivative Financial Instruments for additional information regarding the Company’s derivative instruments.

Provisional Sales Contracts

The value attributable to provisional sales contracts derivative is based on (i) the sales volumes and (ii) the difference in the independent active futures price quotes for the respective index over the term of the pricing period designated in the sales contract and the spot price on the date of sale.

Decommissioning Trust Fund

In April 2024, a decommissioning trust agreement with the Jubilee unit partners to cash fund future retirement costs associated with the Jubilee Field was finalized. Each partner will contribute annually to the trust in proportion to its respective paying interest of the estimated future dismantlement, abandonment and restoration costs associated with the decommissioning of the Jubilee Field. Contributions to the trust are used by the trustee of the fund, the Bank of Ghana, to purchase and sell authorized securities at the direction of the Jubilee unit partners.

As of March 31, 2026, the investments held in the decommissioning trust fund are US Treasury debt securities. We have classified the investments as trading securities and recorded such investments at fair market value as a long-term investment in our consolidated balance sheet using observable inputs including Kosmos’ share of the fund and broker/dealer bid/ask prices of the investments held by the fund at March 31, 2026. Contributions made to the decommissioning trust are reported as investing activities in our consolidated cash flows. All realized and unrealized gains and losses resulting from the sales and maturities or changes in fair value of the securities are recognized in Other income, net. During the three months ended March 31, 2026 and 2025, we contributed $11.6 million and $11.5 million to the decommissioning trust fund, respectively.

The following table summarizes the cost and fair value, purchases, proceeds from the sale and maturities, and the unrealized gains (losses) for Kosmos’ portion of the investments in debt securities held by the decommissioning trust during the three months ended March 31, 2026 and 2025:

Total	$	2,934,126	$	2,801,408	$	3,085,786	$	2,497,101

The carrying values of our 7.125% Senior Notes, 7.750% Senior Notes, 7.500% Senior Notes, 8.750% Senior Notes and 3.125% Convertible Senior Notes represent the principal amounts outstanding less unamortized discounts. The fair values of our 7.125% Senior Notes, 7.750% Senior Notes, 7.500% Senior Notes, 8.750% Senior Notes, 3.125% Convertible Senior Notes and 11.250% Senior Secured Bonds are based on quoted market prices, which results in a Level 1 fair value measurement. The carrying value of the GoA Term Loan Facility and Facility approximates fair value since they are subject to short-term floating interest rates that approximate the rates available to us for those periods.

Nonrecurring Fair Value Measurements - Long-lived assets

Certain long-lived assets are reported at fair value on a non-recurring basis on the Company's consolidated balance sheet. These long-lived assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. Our long-lived assets are reviewed for impairment when changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

The Company calculates the estimated fair values of its long-lived assets using the income approach described in the ASC 820 — Fair Value Measurements. Significant inputs associated with the calculation of estimated discounted future net cash flows include anticipated future production, pricing estimates, capital and operating costs, market-based weighted average cost of capital, and risk adjustment factors applied to reserves. These are classified as Level 3 fair value assumptions. The Company utilizes an average of third-party industry forecasts of Dated Brent, adjusted for location and quality differentials, to determine our pricing assumptions. In order to evaluate the sensitivity of the assumptions, we analyze sensitivities to prices, production, and risk adjustment factors.

During the three months ended March 31, 2026 and 2025, the Company did not recognize impairment of proved oil and gas properties. If we experience material declines in oil pricing expectations in the future, significant increases in our estimated future expenditures or a significant decrease in our estimated production profile, our long-lived assets could be at risk of impairment.

11. Equity-based Compensation

Restricted Stock Units

We record equity-based compensation expense equal to the fair value of share-based payments over the vesting periods of the LTIP awards. We recorded compensation expense from awards granted under our LTIP of $6.0 million and $8.4 million during the three months ended March 31, 2026 and 2025, respectively. The total tax benefit for the three months ended March 31, 2026 and 2025 was $1.0 million and $1.4 million, respectively. Additionally, we recorded a net tax shortfall (windfall) related to equity-based compensation of $7.7 million and $3.1 million for the three months ended March 31, 2026 and 2025, respectively. The fair value of awards vested during the three months ended March 31, 2026 and 2025 was $3.7 million and $19.1 million, respectively. The Company granted restricted stock units with service vesting criteria and a combination of market and service vesting criteria under the LTIP. Substantially all of these grants vest over three years. Upon vesting, restricted stock units become issued and outstanding stock.

For restricted stock units with a combination of market and service vesting criteria, the number of common shares to be issued is determined by comparing the Company’s total shareholder return with the total shareholder return of a predetermined group of peer companies over the performance period and can vest in up to 200% of the awards granted. The grant date fair value ranged from $1.94 to $13.06 per award. The Monte Carlo simulation model utilized multiple input variables that determined the probability of satisfying the market condition stipulated in the award grant and calculated the fair value of the award. The expected volatility utilized in the model was estimated using our historical volatility and the historical volatilities of our peer companies and ranged from 58.0% to 105.0%. The risk-free interest rate was based on the U.S. treasury rate for a term commensurate with the expected life of the grant and ranged from 1.3% to 4.2%.

The following table reflects the outstanding restricted stock units as of March 31, 2026:


		Weighted-		Market / Service	Weighted-
	Service Vesting	Average		Vesting	Average
	Restricted Stock	Grant-Date		Restricted Stock	Grant-Date
	Units	Fair Value		Units	Fair Value

Outstanding at March 31, 2026	5,355	$	2.69	11,515	$	4.27

__________________________________

(1)The restricted stock units with a combination of market and service vesting criteria may vest between 0% and 200% of the originally granted units depending upon market performance conditions. Awards vesting over or under target shares of 100% results in additional shares granted or forfeited, respectively, in the period the market vesting criteria is determined.

As of March 31, 2026, total equity-based compensation to be recognized on unvested restricted stock units is $25.7 million over a weighted average period of 1.93 years. At March 31, 2026, the Company had approximately 2.1 million shares that remain available for issuance under the LTIP.

12. Income Taxes

We evaluate our estimated annual effective income tax rate each quarter, based on current and forecasted business results and enacted tax laws, and apply this tax rate to our ordinary income or loss to calculate our estimated tax expense or benefit. The Company excludes zero statutory tax rate and tax-exempt jurisdictions from our evaluation of the estimated annual effective income tax rate. The tax effect of discrete items are recognized in the period in which they occur at the applicable statutory tax rate.

Income before income taxes is composed of the following:


	Three Months Ended March 31,
	2026		2025
	(In thousands)
United States	$	(51,596)	$	(60,770)
Foreign (1)	(189,491)		(33,261)

(1) Foreign tax expense includes amounts related to Ceiba and Okume Complex located in Block G offshore Equatorial Guinea, which has been classified as assets held for sale. See Note 3 - Acquisitions and Divestitures for additional information.

For the three months ended March 31, 2026 and 2025, our effective tax rate was 6% and (18)%, respectively. For the three months ended March 31, 2026 and March 31, 2025, our overall effective tax rate was impacted by:

•The difference in our 21% U.S. income tax reporting rate and the statutory income tax rates applicable to our foreign operations, primarily in Ghana and Equatorial Guinea,

•Jurisdictions that have a 0% statutory tax rate or that are exempt,

•Jurisdictions where we have incurred losses and have recorded valuation allowances against the corresponding deferred tax assets, and

•Other non-deductible expenses

13. Net Loss Per Share

The following table is a reconciliation between net loss and the amounts used to compute basic and diluted net loss per share and the weighted average shares outstanding used to compute basic and diluted net loss per share. Potentially dilutive securities include shares issuable upon conversion of our 3.125% Convertible Senior Notes using the if-converted method and restricted stock units awards under our equity-based compensation plan.

__________________________________

(1)We excluded restricted stock units of 14.2 million and 7.9 million for the three months ended March 31, 2026 and 2025, respectively, from the computations of diluted net loss per share because the effect would have been anti-dilutive.

(2)Represents the dilutive impact for the Company’s 3.125% Convertible Senior Notes due 2030. As of March 31, 2026, the if-converted value is less than the outstanding principal of the 3.125% Convertible Senior Notes and therefore anti-dilutive. The 3.125% Convertible Senior Notes are subject to a capped call arrangement that potentially reduces the dilutive effect. Any potential impact of the capped call arrangement is excluded from this table as any proceeds under the capped call arrangement are considered anti-dilutive.

On March 10, 2026 the Company launched and priced a registered underwritten public offering of 112.1 million shares of common stock, par value $0.01, resulting in net proceeds to Kosmos of approximately $206.4 million. The offering closed on March 12, 2026.

14. Commitments and Contingencies

From time to time, we are involved in litigation, regulatory examinations and administrative proceedings primarily arising in the ordinary course of our business in jurisdictions in which we do business. Although the outcome of these matters cannot be predicted with certainty, management believes that the likelihood of an unfavorable outcome having a material impact is neither reasonably possible nor probable of occurring.

As of March 31, 2026, we have a commitment to drill one development well related to our assets held for sale in Equatorial Guinea. As part of the license extensions of WCTP and DT Petroleum Agreements in Ghana, we have a commitment to drill a minimum of ten development wells under the amended Jubilee plan of development.

In April 2024, a decommissioning trust agreement with the Jubilee unit partners to cash fund future retirement costs associated with the Jubilee Field was finalized. The operator currently estimates the total remaining commitment to be approximately $111.0 million as of March 31, 2026, net to Kosmos, which will be funded annually by Kosmos over an estimated fourteen year period.

Performance Obligations

As of March 31, 2026 and December 31, 2025, the Company had performance and supplemental bonds totaling $150.5 million and $151.6 million, respectively, related to bonding requirements stipulated by the BOEM and other third parties for anticipated plugging and abandonment costs of certain wells and the removal of certain facilities in our Gulf of America fields.

Once the Tortue Phase 1 SPA Commercial Operations Date was achieved in February 2026, we have a commitment to our buyer under the Tortue Phase 1 SPA, BP Gas Marketing Limited, to deliver our proportionate share of a minimum annual contract quantity of LNG of 127,951,000 MMBtu, which is equivalent to approximately 2.45 million tonnes per annum, subject to certain downward adjustments by the sellers. Under certain circumstances, in the event the annual quantities provided are lower than the minimum annual contract quantity, Kosmos may be obligated to credit or pay a portion of the Contract Price to BP Gas Marketing Limited for the shortfall volumes.

In February 2026, Tullow, as Operator of the TEN partnership, executed the final Sale and Purchase Agreement enabling the partnership to acquire the TEN FPSO from MODEC, Inc. at the end of its current lease in 2027 for a gross purchase price of $205.0 million. We have a commitment to Tullow for our proportionate share of the gross purchase price.

16. Business Segment Information

Kosmos is engaged in a single line of business, which is the exploration, development and production of oil and gas. At March 31, 2026, the Company had operations in four geographic reporting segments: Ghana, Equatorial Guinea, Mauritania/Senegal and the Gulf of America. The Company’s Chief Operating Decision Maker (“CODM”) is the Chief Executive Officer, who makes decisions about allocating resources and assessing performance for the entire company. To assess performance of the reporting segments, the CODM regularly reviews oil and gas revenues, oil and gas production costs, exploration expenses and capital expenditures by reporting segment in deciding how to allocate resources and in assessing performance. Capital expenditures, as defined by the Company, may not be comparable to similarly titled measures used by other companies and should be considered in conjunction with our consolidated financial statements and notes thereto.

Overview

Recent Developments

Corporate

On January 12, 2026, we received net proceeds of $98.5 million from the funding of the second tranche of the GoA Term Loan after deducting fees and expenses. On January 13, 2026, the net proceeds were used, together with cash on hand, to complete the redemption of the remaining outstanding balance of $100.0 million of the 7.125% Senior Notes due 2026. On March 24, 2026, we made a voluntary prepayment of $53.6 million against the GoA Term Loan. On May 1, 2026, the GoA Term Loan Facility was amended to apply this prepayment in full satisfaction of the scheduled principal amount due on the first scheduled amortization payment date on June 30, 2026, and then ratably to all remaining scheduled principal payments of the outstanding loans. The amendment also deferred all future scheduled amortization payment dates in 2026, 2027 and 2028 such that they will now be due on October 1, January 1, April 1 and July 1 in each of 2026, 2027 and 2028. As a result of the amendment, there is only one remaining scheduled amortization payment in 2026 to be paid on October 1, 2026.

On January 16, 2026, the Company announced the pricing of $350.0 million aggregate principal amount of 11.250% senior secured bonds due 2031 in the Nordic market (the “GTA Nordic bonds”). In the first quarter of 2026, the Company used the net proceeds from the Nordic bond offering to fund the repurchase of an aggregate principal amount of $249.8 million of the 7.750% Senior Notes due 2027 pursuant to the Company’s cash tender offer announced on January 12, 2026 and open market repurchases, and to make a voluntary early principal repayment of $100.0 million on outstanding borrowings under the Facility.

On March 10, 2026, the Company launched and priced a registered underwritten public offering of 112.1 million shares of common stock, resulting in net proceeds to Kosmos of approximately $206.4 million. The offering closed on March 12, 2026.

In April 2026, during the Spring 2026 redetermination, the Company’s lending syndicate approved a borrowing base at approximately $1.25 billion for the Facility, and a further reduction to approximately $1.2 billion upon the close of the sale of all our participating interest in the Ceiba Field and Okume Complex production assets located in Block G offshore Equatorial Guinea.

Ghana

During the first quarter of 2026, Ghana production averaged approximately 103,300 Boepd gross (35,400 Boepd net).

Jubilee development drilling progressed in the first quarter of 2026 bringing two producer wells successfully online during the first quarter of 2026. The remaining development drilling campaign in 2026 is planned to include three additional producer wells and one additional water injector well.

In December 2025, the Jubilee and TEN partnerships received approval from the Government of Ghana to extend to 2040 the WCTP and the DT licenses, which cover the Jubilee and TEN fields offshore Ghana. Additionally, starting from July 2036, Ghana National Petroleum Corporation’s share in the fields will increase by an additional 10% interest and the joint venture partners’ shares will decrease pro rata. As part of the extension of the Petroleum Agreements, the Jubilee plan of

development is amended to include up to twenty additional wells in the fields. Additionally, in December 2025, as part of the extension of the WCTP and DT Petroleum Agreements, the Ghana partners and Government of Ghana have approved an amended gas sales agreement at a price of $2.50 per MMBtu through the extended expiration date of 2040 for the WCTP and DT licenses.

In February 2026, Tullow Oil plc, as Operator of the TEN partnership, executed the final Sale and Purchase Agreement enabling the partnership to acquire the TEN FPSO from MODEC, Inc. at the end of its current lease in 2027 for a gross purchase price of $205.0 million.

Gulf of America

Production from the Gulf of America averaged approximately 16,800 Boepd net (~84% oil) for the first quarter of 2026.

On Tiberius, Kosmos (operator, 50% working interest) continues to progress the development with our partner Occidental Petroleum Corporation (“Oxy”) (50% working interest). A production handling agreement for the Oxy-operated Lucius platform was signed in the third quarter of 2025. We achieved a final investment decision in March 2026 with first oil targeted in the second half of 2028. We are also working on a potential farm down to reduce Kosmos’ working interest to approximately 33%, which is expected around the middle of 2026.

At Winterfell, the partnership spud Winterfell-5 in April 2026. Winterfell-5 is designed as a twin well to Winterfell-3 and is expected to restore production from the Winterfell-3 fault block. Winterfell-5 is expected online in the third quarter of 2026. In April 2026, Winterfell-2 was shut-in pending a future intervention.

In February 2026, Kosmos entered into a strategic alliance with Shell, exchanging interests in five exploration blocks in the Norphlet trend. Shell and Kosmos now have alignment covering ten blocks in the Gulf of America to explore multiple prospects, including Trailblazer. Drilling of the Trailblazer exploration well is planned for the first half of 2027, with Kosmos designated as development operator.

Equatorial Guinea

Production in Equatorial Guinea averaged approximately 16,000 Bopd gross (5,600 Bopd net) in the first quarter of 2026, with remediation work on the failed subsea multiphase flow pump (MPP) at Ceiba progressing.

On February 24, 2026, we entered into a Share Sale and Purchase Agreement with a subsidiary of Panoro Energy ASA for the sale of all our 40.4% participating interest in the Ceiba Field and Okume Complex production assets located in Block G offshore Equatorial Guinea for upfront cash consideration of $180.0 million, subject to certain adjustments and future contingent consideration of up to $39.5 million, comprised of $12.5 million linked to future production performance at the Ceiba field and $9.0 million payable in each of the years 2027, 2028 and 2029, subject to certain production and oil price thresholds. The transaction has an effective date of January 1, 2025, has received approval from the Government of Equatorial Guinea and completion only remains subject to CEMAC customary approval. While we expect to close the transaction around the middle of 2026, there can be no assurances that closing will ultimately occur or that it may not be delayed. Operating results throughout this Form 10-Q continue to include the operating results of the EG business on the basis that the transaction has not yet closed and that the Company continues to own all of the participating interest in the Ceiba Field and Okume Complex production assets located in Block G offshore Equatorial Guinea. All such references to the Company’s future plans and expectations for the Equatorial Guinea business unit should therefore be read in light of the ongoing transaction.

In the first quarter of 2026, we withdrew from Block EG-01 offshore Equatorial Guinea.

Mauritania and Senegal

Greater Tortue Ahmeyim (GTA) Field

Production in Mauritania and Senegal from GTA averaged approximately 69,800 Boepd gross (17,000 Boepd net) in the first quarter of 2026, approximately 2.85 million tonnes per annum, or 5% above FLNG nameplate capacity.

Sao Tome and Principe

Block 5 offshore Sao Tome and Principe is scheduled to expire during the second quarter of 2026 and, accordingly, we wrote off related leasehold costs.

Oil and gas revenue. Oil and gas revenue increased by $80.6 million during the three months ended March 31, 2026 as compared to the three months ended March 31, 2025 primarily as a result of higher production and sales volumes at Jubilee and GTA, with GTA producing at 5% above FLNG nameplate capacity offset by lower average realized oil and gas prices. We

Table of Contents

sold 6,643 MBoe at an average realized price per barrel equivalent of $55.81 during the three months ended March 31, 2026 and 4,445 MBoe at an average realized price per barrel equivalent of $65.27 during the three months ended March 31, 2025.

Oil and gas production. Oil and gas production costs decreased by $36.7 million during the three months ended March 31, 2026 as compared to the three months ended March 31, 2025 primarily as a result of lower routine operating costs across all of our business units and decreased workover expense in our Gulf of America business unit.

Exploration expenses. Exploration expenses increased by $10.1 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025 primarily as a result of the write-off of exploration leasehold costs during the first quarter of 2026, partially offset by decreased seismic, geological and geophysical studies and related costs in the first quarter of 2026 as part of the Company’s focus on managing costs across our portfolio.

General and administrative expenses. General and administrative expenses increased $1.5 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025 primarily as a result of lower technical rate fees in the first quarter of 2026, partially offset by lower gross general and administrative costs.

Depletion, depreciation and amortization. Depletion, depreciation and amortization decreased by $0.8 million during the three months ended March 31, 2026, as compared with the three months ended March 31, 2025 primarily as a result lower depletion rates per boe across our portfolio offset by higher sales volumes at Jubilee and GTA.

Interest and other financing costs, net. Interest and other financing costs, net increased by $7.0 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025 primarily as a result of increased debt and lower capitalized interest as a result of the Yakaar and Teranga write-off in December 2025.

Derivatives, net. During the three months ended March 31, 2026 and 2025, we recorded a loss of $252.0 million and a loss of $6.7 million, respectively, on our outstanding hedge positions. The amounts recorded were a result of changes in the forward oil price curve during the respective periods.

Income tax expense. For the three months ended March 31, 2026 and 2025, changes to our effective tax rates are driven by which tax jurisdictions our income (loss) before income taxes is generated. The jurisdictions in which we operate have statutory tax rates ranging from 0% to 35%.

Liquidity and Capital Resources

We are actively engaged in an ongoing process of anticipating and meeting our funding requirements related to our strategy as a deepwater exploration and production company. We have historically met our funding requirements through cash flows generated from our operating activities and obtained additional funding from issuances of equity and debt, as well as partner carries.

Oil prices are historically volatile and could negatively impact our ability to generate sufficient operating cash flows to meet our funding requirements. This oil price volatility could impact our ability to comply with our financial covenants. To partially mitigate this price volatility, we maintain an active hedging program and review our capital spending program on a regular basis. Our investment decisions are based on longer-term commodity prices based on the nature of our projects and development plans. Current commodity prices, combined with our hedging program and our current liquidity position is expected to support our remaining capital program for 2026.

As such, our 2026 capital budget is based on our exploitation plans for our producing assets in Ghana, Equatorial Guinea, Mauritania, Senegal and the Gulf of America, and our development activities in the Gulf of America and in Mauritania and Senegal.

Our future financial condition and liquidity can be impacted by, among other factors, the success of our exploration, appraisal and exploitation drilling programs, the number of commercially viable oil and natural gas discoveries made and the quantities of oil and natural gas discovered, the speed with which we can bring such discoveries to production, the reliability of our oil and gas production facilities, our ability to continuously export oil, natural gas and LNG and our ability to secure and maintain partners and their alignment with respect to capital plans, the actual cost of exploration, appraisal, exploitation and development of our oil and natural gas assets, and coverage of any claims under our insurance policies.

Net cash provided by (used in) operating activities. Net cash provided by operating activities for the three months ended March 31, 2026 was $106.6 million compared with net cash used in operating activities for the three months ended March 31, 2025 of $0.9 million. The increase in cash provided by operating activities in the three months ended March 31, 2026 when compared to the same period in 2025 is primarily a result of higher production and sales volumes at Jubilee and GTA, lower routine oil and gas production costs across all of our business units and decreased workover expense in our Gulf of America business unit, partially offset by lower average realized oil and gas prices for the three months ended March 31, 2026.

(1) When our debt cover ratio exceeds 2.50x, we are required under the Facility to maintain a restricted cash balance that is sufficient to meet the payment of interest and fees for the next six-month period on the 7.750% Senior Notes, the 7.500% Senior Notes, the 8.750% Senior Notes and the 3.125% Convertible Senior Notes or the Facility, whichever is greater. During the first quarter of 2025, the Facility lenders waived the requirement to maintain a restricted cash balance until the March 31, 2026 financial covenant test date. Our debt cover ratio for the most recent March 31, 2026 financial covenant test date exceeded 2.50x and the estimated restricted cash funding requirement is approximately $47.0 million. We are currently in discussions with the Facility lenders seeking approval to extend the prior waiver, but if no approval is granted then we plan to start funding the debt service reserve account in the second quarter, as required under the terms of the Facility.

(2) Excludes $80.1 million TEN FPSO finance lease liability. For purposes of the debt cover ratio calculation under the Facility, the finance lease liability is included in net debt.

Capital Expenditures and Investments

For our 2026 capital expenditure budget, we expect to incur capital costs as we:

• drill additional infill wells in Ghana and the Gulf of America;

• advance development efforts in the Gulf of America and in Mauritania and Senegal; and

• execute facilities integrity activities in Equatorial Guinea.

We have relied on a number of assumptions in budgeting for our future activities. These include the number of wells we plan to drill, our paying interests in our operations including disproportionate payment amounts, the costs involved in developing or participating in the development of a prospect, the timing of third‑party projects, the availability of suitable equipment and qualified personnel and our cash flows from operations. We also evaluate potential corporate and asset acquisition opportunities to support and expand our asset portfolio which may impact our budget assumptions. These assumptions are inherently subject to significant business, political, economic, regulatory, health, environmental and competitive uncertainties, contingencies and risks, all of which are difficult to predict and many of which are beyond our control. We may need to raise additional funds more quickly if market conditions deteriorate, or one or more of our assumptions proves to be incorrect, or if we choose to expand our acquisition, exploration, appraisal, development efforts or any other activity more rapidly than we presently anticipate. We may decide to raise additional funds before we need them if the conditions for raising capital are favorable. We may seek to sell assets, equity or debt securities or obtain additional bank

credit facilities. The sale of equity securities could result in dilution to our shareholders. The incurrence of additional indebtedness could result in increased fixed obligations and additional covenants that could restrict our operations.

2026 Capital Program

We estimate we will spend in aggregate around $350 million of capital for the year ending December 31, 2026, excluding any acquisitions or divestiture of oil and gas properties during the year. This capital expenditure budget consists of:

•Approximately $275 million related to maintenance activities across our producing Ghana and Gulf of America assets, including infill development drilling and TEN FPSO purchase payments;

•Approximately $60 million related to progressing our development programs in the Gulf of America and in Mauritania and Senegal;

•Approximately $15 million related to facilities integrity activities in Equatorial Guinea.

The ultimate amount of capital we will spend may fluctuate materially based on market conditions and the success of our exploitation and drilling results among other factors. Our future financial condition and liquidity will be impacted by, among other factors, our level of production of oil, natural gas and LNG and the prices we receive from the sale of oil, natural gas and LNG, and our ability to effectively hedge future production volumes, the success of our multi-faceted infrastructure-led exploration, appraisal and development drilling programs, the number of commercially viable oil and natural gas discoveries made and the quantities of oil and natural gas discovered, the speed with which we can bring such discoveries to production, our partners’ alignment with respect to capital plans, and the actual cost of exploration, appraisal, exploitation and development of our oil and natural gas assets, and coverage of any claims under our insurance policies.

Significant Sources of Capital

Facility

In April 2026 during the Spring 2026 redetermination, the Company’s lending syndicate approved a borrowing base at approximately $1.25 billion. Following closing of the sale of all our participating interest in the Ceiba Field and Okume Complex production assets located in Block G offshore Equatorial Guinea, the Company’s production assets in Equatorial Guinea will no longer be included in the borrowing base amount, and we have agreed with the lending syndicate to further reduce the borrowing base to approximately $1.2 billion.

The Facility provides a revolving credit and letter of credit facility. The availability period for the revolving credit facility expires one month prior to the final maturity date. The letter of credit facility expires on the final maturity date. The available facility amount is subject to borrowing base constraints and, beginning on April 1, 2027, outstanding borrowings will be constrained by an amortization schedule. The Facility has a final maturity date of December 31, 2029. As of March 31, 2026, we had no letters of credit issued under the Facility. We have the right to cancel all the undrawn commitments under the amended and restated Facility.

If an event of default exists under the Facility, the lenders can accelerate the maturity and exercise other rights and remedies, including the enforcement of security granted pursuant to the Facility over certain assets. Leverage was elevated in 2025 given lower oil prices and the impact of operation costs during the ramp-up of the GTA Phase 1 project combined with lower company production. As a result, in July 2025, the Company and the Facility lenders agreed to amend the debt cover ratio required under the Facility. The amendment made this covenant less restrictive for the following two scheduled financial covenant assessment dates, up to a maximum of 4.0x and 4.25x, respectively, and thereafter returned to the originally agreed upon ratio of 3.50x for assessment dates thereafter. In February 2026, we further amended the debt cover ratio calculation through September 2026. This most recent amendment makes the covenant less restrictive for the following two scheduled financial covenant assessment dates, up to a maximum of 4.5x and 4.25x respectively, and for purposes of the financial covenant assessment date in March 2026, the calculation was made excluding the Company’s Mauritania and Senegal business

Table of Contents

unit. The debt cover ratio returns to the originally agreed upon ratio of 3.5x for assessment dates thereafter. The change was intended to align the covenant calculation with recent business operations, lower oil prices and the impact of operating costs during the ramp-up of the GTA Phase 1 project on our results of operations. The Facility contains customary cross default provisions.

The U.S. and many foreign economies continue to experience uncertainty driven by varying macroeconomic conditions. Although some of these economies have shown signs of improvement, macroeconomic recovery remains uneven. Uncertainty in the macroeconomic environment and associated global economic conditions have resulted in extreme volatility in credit, equity, and foreign currency markets, including the European sovereign debt markets and volatility in various other markets. If any of the financial institutions within our Facility are unable to perform on their commitments, our liquidity could be impacted. We actively monitor all of the financial institutions participating in our Facility. None of the financial institutions have indicated to us that they may be unable to perform on their commitments. In addition, we periodically review our banking and financing relationships, considering the stability of the institutions and other aspects of the relationships. Based on our monitoring activities, we currently believe our banks will be able to perform on their commitments.

Senior Notes

We have three series of senior notes outstanding as of March 31, 2026, which we collectively refer to as the “Senior Notes.” In January 2026, we used the net proceeds of $98.5 million from funding the second tranche of the GoA Term Loan Facility, together with cash on hand, to fund the redemption of the remaining $100.0 million of the 7.125% Senior Notes due 2026. Our 7.750% Senior Notes have an outstanding balance of $100.2 million and mature on May 1, 2027. Interest is payable on the 7.750% Senior Notes each May 1 and November 1. Our 7.500% Senior Notes have an outstanding balance of approximately $400.3 million and mature on March 1, 2028. Interest is payable on the 7.500% Senior Notes each March 1 and September 1. Our 8.750% Senior Notes have an outstanding balance of $500.0 million and mature on October 1, 2031. Interest is payable on the 8.750% Senior Notes each April 1 and October 1.

The Senior Notes are senior, unsecured obligations of Kosmos Energy Ltd. and rank equally in right of payment with all of its existing and future senior indebtedness (including the 3.125% Convertible Senior Notes) and rank effectively junior in right of payment to all of its existing and future secured indebtedness (including all borrowings under the Facility, the GoA Term Loan Facility and, with respect to certain of our subsidiaries that own our assets in Mauritania and Senegal, the GTA Nordic bonds). The GTA Nordic bonds are fully and unconditionally guaranteed by the Company, as well as the Company’s wholly-owned subsidiaries, Kosmos Energy Tortue Finance, Kosmos Energy Senegal, Kosmos Energy Investments Senegal Limited and Kosmos Energy Mauritania. The GTA Nordic bonds are also guaranteed on an unsecured basis by certain of the Company’s subsidiaries that also guarantee the Senior Notes on a senior, unsecured basis. The Senior Notes are jointly and severally guaranteed on a senior, unsecured basis by certain subsidiaries owning the Company’s Gulf of America assets, and on a subordinated, unsecured basis by entities that borrow under, or guarantee, our Facility.

3.125% Convertible Senior Notes due 2030

We have one series of senior convertible notes outstanding. Our 3.125% Convertible Senior Notes mature on March 15, 2030, unless earlier converted, redeemed or repurchased. Interest is payable in arrears each March 15 and September 15, commencing September 15, 2024.

The 3.125% Convertible Senior Notes are senior, unsecured obligations of Kosmos Energy Ltd. and rank equal in right of payment with all of its existing and future senior indebtedness (including all borrowings under the Senior Notes) and rank effectively junior in right of payment to all of its existing and future secured indebtedness (including all borrowings under the Facility, to the extent of the value of the assets securing such indebtedness). The 3.125% Convertible Senior Notes are guaranteed on a senior, unsecured basis by certain of our existing subsidiaries that guarantee on a senior basis the Senior Notes, and, in certain circumstances, certain of our other existing or future subsidiaries. The 3.125% Convertible Senior Notes are guaranteed on a subordinated, unsecured basis by certain of our existing subsidiaries that borrow under or guarantee the Facility and guarantee on a subordinated basis the Senior Notes, and, in certain circumstances, certain of our other existing or future subsidiaries.

The 3.125% Convertible Senior Notes indenture contains customary terms and covenants.

In connection with the issuance of the 3.125% Convertible Senior Notes, the Company entered into capped call transactions (the “Capped Call Transactions”). The Capped Call Transactions are generally expected to reduce potential dilution to holders of our common stock upon any conversion of the 3.125% Convertible Senior Notes and/or offset any cash payments that we are required to make in excess of the principal amount of any 3.125% Convertible Senior Notes that are converted, as the case may be, with such reduction and/or offset subject to a cap.

GoA Term Loan Facility

On September 24, 2025, the Company entered into a senior secured term loan credit agreement secured by first priority liens on all of the Company’s Gulf of America assets (as defined in the credit agreement). The GoA Term Loan Facility is structured in two tranches, with the first tranche consisting of a four-year term loan in an aggregate principal amount of $150.0 million, which was funded on October 1, 2025, and a second tranche of an additional $100.0 million, which was funded in January 2026. The net proceeds were used, together with cash on hand, to fund the redemption of $250.0 million in aggregate of the 7.125% Senior Notes due in 2026. On March 24, 2026, we made a voluntary prepayment of $53.6 million against the GoA Term Loan. On May 1, 2026, the GoA Term Loan Facility was amended to apply this prepayment in full satisfaction of the scheduled principal amount due on the first scheduled amortization payment date on June 30, 2026, and then ratably to all remaining scheduled principal payments of the outstanding loans. The amendment also deferred all future scheduled amortization payment dates in 2026, 2027 and 2028 such that they will now be due on October 1, January 1, April 1 and July 1 in each of 2026, 2027 and 2028. As a result of the amendment, there is only one remaining scheduled amortization payment in 2026 to be paid on October 1, 2026.

GTA Nordic Bonds

In January 2026, we issued one series of senior secured GTA Nordic bonds totaling $350.0 million. Our 11.250% senior secured GTA Nordic bonds mature in January 2031, unless earlier redeemed or repurchased. Interest is payable semi-annually in arrears each July 29 and January 29, commencing July 29, 2026.

The GTA Nordic bonds were issued by Kosmos Energy GTA Holdings, a wholly-owned subsidiary of Kosmos Energy Ltd., and are fully and unconditionally guaranteed by the Company, as well as the Company’s wholly-owned subsidiaries, Kosmos Energy Tortue Finance, Kosmos Energy Senegal, Kosmos Energy Investments Senegal Limited and Kosmos Energy Mauritania. The GTA Nordic bonds are also guaranteed on an unsecured basis by certain of the Company’s subsidiaries that also guarantee the Company’s existing senior unsecured notes.

The Bond Terms governing the GTA Nordic bonds also require Kosmos Energy GTA Holdings to maintain certain financial covenants including:

•Minimum Liquidity (as defined in the Bond Terms) of not less than $17.5 million or 5% of the outstanding GTA Nordic bonds, whichever is greater; and

•an Asset Coverage Ratio (as defined in the Bond Terms) of at least 1.25x.

(1)The amounts included in the table represent principal maturities only. The scheduled maturities of debt related to the Facility are based on the level of borrowings and the available borrowing base as of March 31, 2026. Any increases or decreases in the level of borrowings or increases or decreases in the available borrowing base would impact the scheduled maturities of debt during the next five years and thereafter.

(2)Represents the period April 1, 2026 through December 31, 2026.

(3)Primarily relates to corporate and foreign office leases.

(4)Represents gross contractual obligations to execute planned future capital projects. Other joint owners in the properties operated by Kosmos will be billed for their working interest share of such costs. Does not include our share of operator’s purchase commitments for jointly owned fields and facilities where we are not the operator and excludes commitments for exploration activities, including well commitments and seismic obligations, in our petroleum contracts. The Company’s liabilities for asset retirement obligations associated with the dismantlement, abandonment and restoration costs of oil and gas properties are not included. See Note 15 - Additional Financial Information for additional information regarding these liabilities.

(5)In April 2024, a decommissioning trust agreement with the Jubilee unit partners to cash fund future retirement costs associated with the Jubilee Field was finalized. The operator currently estimates the total commitment to be approximately $111.0 million as of March 31, 2026, net to Kosmos, which will be funded annually by Kosmos over an estimated fourteen year period. It is possible that our funding requirements could change based on future changes in the decommissioning plan or estimates.

Critical Accounting Policies

We consider accounting policies related to our revenue recognition, exploration and development costs, income taxes, estimates of proved oil and gas reserves, asset retirement obligations, impairment of long-lived assets, and acquisition accounting as critical accounting policies. The policies include significant estimates made by management using information available at the time the estimates are made. However, these estimates could change materially if different information or assumptions were used. Other than items discussed in Note 2 — Accounting Policies, there have been no changes to our critical accounting policies which are summarized in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” section in our annual report on Form 10-K, for the year ended December 31, 2025.

Cautionary Note Regarding Forward-looking Statements

This quarterly report on Form 10-Q contains estimates and forward-looking statements, principally in “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Our estimates and forward-looking statements are mainly based on our current expectations and estimates of future events and trends, which affect or may affect our businesses and operations. Although we believe that these estimates and forward-looking statements are based upon reasonable assumptions, they are subject to several risks and uncertainties and are made in light of information currently available to us.

The words “believe,” “may,” “will,” “aim,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “plan” and similar words are intended to identify estimates and forward-looking statements. Estimates and forward-looking statements speak only as of the date they were made, and, except to the extent required by law, we undertake no obligation to update or to review any estimate and/or forward-looking statement because of new information, future events or other factors. Estimates and forward-looking statements involve risks and uncertainties and are not guarantees of future performance. As a result of the risks and uncertainties described above, the estimates and forward-looking statements discussed in this quarterly report on Form 10-Q might not occur, and our future results and our performance may differ materially from those expressed in these forward-looking statements due to, including, but not limited to, the factors mentioned above. Because of these uncertainties, you should not place undue reliance on these forward-looking statements.

Item 3. Qualitative and Quantitative Disclosures About Market Risk

The primary objective of the following information is to provide forward-looking quantitative and qualitative information about our potential exposure to market risks. The term “market risks” as it relates to our currently anticipated transactions refers to the risk of loss arising from changes in commodity prices and interest rates. These disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonably possible losses. This forward-looking information provides indicators of how we view and manage ongoing market risk exposures. We enter into market-risk sensitive instruments for purposes other than to speculate.

We manage market and counterparty credit risk in accordance with our policies. In accordance with these policies and guidelines, our management determines the appropriate timing and extent of derivative transactions. See “Item 8. Financial Statements and Supplementary Data — Note 2 — Accounting Policies, Note 9 — Derivative Financial Instruments and Note 10 — Fair Value Measurements” section of our annual report on Form 10-K for a description of the accounting procedures we follow relative to our derivative financial instruments.

The following table reconciles the changes that occurred in fair values of our open derivative contracts during the three months ended March 31, 2026:

Commodity Price Risk

The Company’s revenues, earnings, cash flows, capital investments, debt capacity and, ultimately, future rate of growth are highly dependent on the prices we receive for our crude oil, which have historically been very volatile. Substantially all of our oil sales are indexed against Dated Brent, and Heavy Louisiana Sweet. Oil prices in the first three months of 2026 ranged between $60.98 and $127.24 per Bbl for Dated Brent, with Heavy Louisiana Sweet experiencing similar volatility during the first three months of 2026.

Commodity Derivative Instruments

We enter into various oil derivative contracts to mitigate our exposure to commodity price risk associated with anticipated future oil production. These contracts currently consist of swaps, collars, put options and call options. In regards to our obligations under our various commodity derivative instruments, if our production does not exceed our existing hedged positions, our exposure to our commodity derivative instruments would increase. In addition, a reduction in our ability to access credit could reduce our ability to implement derivative contracts on commercially reasonable terms.
