Kosmos Energy Ltd. ("Kosmos" or the "Company,") announced that its wholly-owned subsidiary, Kosmos Energy GTA Holdings (the "Issuer"), intends to offer, subject to market conditions and other factors, $350 million aggregate principal amount of senior secured bonds in the Nordic bond market. The senior bonds will be due in 2031 and will be 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 senior bonds will also be guaranteed on an unsecured basis by certain of the Company's subsidiaries that also guarantee the Company's existing senior unsecured notes.

Kosmos intends to use the net proceeds from the offering to fund the tender offer for $250 million aggregate principal amount of its 7.750% Senior Notes due 2027 (including paying any related premiums, fees and expenses), to repay certain borrowings under its reserve-based lending facility and for general corporate purposes.

The senior bonds to be offered have not been and will not be registered under the Securities Act of 1933, as amended (the "Securities Act"), or any state securities laws, and the securities may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities or blue sky laws. The senior bonds will be offered only to persons reasonably believed to be qualified institutional buyers in reliance on the exemption from registration set forth in Rule 144A under the Securities Act and, outside the United States, to non-U.S. persons in reliance on the exemption from registration set forth in Regulation S under the Securities Act.

This press release is being issued pursuant to, and in accordance with, Rule 135c under the Securities Act, and is neither an offer to sell nor a solicitation of an offer to buy the senior bonds or any other securities and it does not constitute an offer to purchase or a solicitation to sell any notes subject to the tender offer. This press release shall not constitute an offer to sell or a solicitation of an offer to buy, or a sale of, the senior bonds or any other securities in any jurisdiction in which such offer, solicitation or sale is unlawful.
