Kosmos Energy Ltd. Prices Upsized Offering of $350 Million 3.125% Convertible Senior Notes Due 2030

March 6, 2024

Dallas, March 6, 2024 - Kosmos Energy Ltd. (NYSE/LSE: KOS) ("Kosmos" or the "Company"), announced today that it has priced a private offering of $350 million aggregate principal amount of its 3.125% convertible senior notes due 2030 (the "notes"), which represents a $50 million increase in principal amount from the previously announced offering size. The Company also granted the initial purchasers an option to purchase up to an additional $50 million aggregate principal amount of notes, for settlement within a 13-day period beginning on, and including, the date on which the notes are first issued. The offering is expected to close on March 8, 2024, subject to customary closing conditions.

The notes will be senior, unsecured obligations of the Company. The notes will rank pari passu with the Company's existing senior notes and the Company's revolving credit facility. The notes will be guaranteed (i) on a senior, unsecured basis by certain of the Company's existing subsidiaries that guarantee on a senior basis the Company's revolving credit facility and the Company's existing senior notes, and (ii) on a subordinated, unsecured basis by certain of the Company's existing subsidiaries that borrow under or guarantee the Company's commercial debt facility and guarantee on a subordinated basis the Company's revolving credit facility and the Company's existing senior notes. Upon conversions of the notes, the Company will satisfy its conversion obligation by paying cash up to the aggregate principal amount of the notes to be converted, and paying or delivering, as the case may be, cash, shares of the Company's common stock or a combination of cash and shares of the Company's common stock, at the Company's election, in respect of the remainder, if any, of its conversion obligation in excess of the aggregate principal amount of the notes to be converted. The notes will have an initial conversion rate of 142.4501 shares of the Company's common stock per $1,000 principal amount of notes (which is subject to adjustment in certain circumstances). This is equivalent to an initial conversion price of approximately $7.02 per share. The initial conversion price represents a premium of approximately 30.0% to the $5.40 per share closing price of the Company's common stock on The New York Stock Exchange on March 5, 2024.

The notes will accrue interest at an annual rate of 3.125%, payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2024. The notes will mature on March 15, 2030, unless earlier repurchased, redeemed or converted. Prior to December 15, 2029, the notes will be convertible at the option of the holders only upon the occurrence of specified events, and thereafter until the close of business on the second scheduled trading day immediately preceding the maturity date, the notes will be convertible at any time. In the event of certain tax law changes, the Company may redeem the notes in whole, but not in part. In addition, the Company may redeem for cash all or any portion of the notes (subject to a partial redemption limitation), at the Company's option, on or after March 22, 2027 and prior to the 41st scheduled trading day immediately preceding the maturity date, if the last reported sale price per share of the Company's common stock has been at least 130% of the conversion price for a specified period of time. The redemption price will be equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

The Company estimates that the net proceeds from this offering will be approximately $340.4 million (or approximately $389.0 million if the initial purchasers exercise in full their option to purchase additional notes), after deducting discounts payable to the initial purchasers. The Company intends to use the net proceeds from the sale of the notes to (i) repay a portion of outstanding indebtedness under the Company's commercial debt facility; (ii) pay the cost of the capped call transactions described below, using net proceeds of approximately $43.6 million; and (iii) pay fees and expenses related to the offering.

In connection with the pricing of the notes, the Company entered into privately negotiated capped call transactions with certain of the initial purchasers of the notes or their respective affiliates and certain other financial institutions (the "option counterparties"). The capped call transactions are expected generally to reduce potential dilution to the Company's common stock upon any conversion of the notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted notes, as the case may be, with such reduction and/or offset subject to a cap. The cap price of the capped call transactions will initially be $10.80, which represents a premium of 100.0% above the last reported sale price of the Company's common stock on The New York Stock Exchange on March 5, 2024, and is subject to customary anti-dilution adjustments. If the initial purchasers of the notes exercise their option to purchase additional notes, the Company expects to enter into additional capped call transactions with the option counterparties and use a portion of the net proceeds from the sale of the additional notes to pay the cost of such additional capped call transactions.

In connection with establishing their initial hedges of the capped call transactions, the Company expects the option counterparties or their respective affiliates to enter into various derivative transactions with respect to the Company's common stock concurrently with or shortly after the pricing of the notes, and may unwind these various derivative transactions and purchase the Company's common stock in open market transactions shortly after the pricing of the notes. This activity could increase (or reduce the size of any decrease in) the market price of the Company's common stock or the notes at that time.

In addition, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to the Company's common stock and/or purchasing or selling the Company's common stock or other securities of the Company in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are likely to do so during any observation period related to a conversion of notes). This activity could also cause or avoid an increase or a decrease in the market price of the Company's common stock or the notes, which could affect the ability of noteholders to convert the notes and, to the extent the activity occurs during any observation period related to a conversion of the notes, it could affect the number of shares and value of the consideration that noteholders will receive upon conversion of the notes.

The offering is being made to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"). The offer and sale of the notes, the guarantees and any shares of the Company's common stock issuable upon conversion of the notes have not been and will not be registered under the Securities Act, or under any state securities laws, and the notes and such shares may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws.

This announcement does not constitute an offer to sell or the solicitation of an offer to buy the notes in the offering, nor shall there be any sale of such notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
