Kosmos Energy Announces Secondary Public Offering of Common Shares and Share Repurchase

DALLAS - November 27, 2018, Kosmos Energy Ltd. ("Kosmos") (NYSE/LSE: KOS) announced post US-market close on November 26, 2018 that funds affiliated with Warburg Pincus LLC ("Warburg Pincus" or the "Selling Shareholder"), have agreed to sell an aggregate of 15 million of Kosmos's common shares in a registered underwritten public offering (the "Offering"). The Selling Shareholder expects to grant the underwriter an option to purchase up to an additional 2.25 million common shares on the same terms and conditions, exercisable within 30 days. Kosmos will not receive any of the proceeds from the sale of the common shares. Barclays is acting as the underwriter of the Offering.

In addition, Kosmos announced that it has agreed to repurchase 35 million of Kosmos's common shares from Warburg Pincus in a separate, privately negotiated Share Repurchase Agreement (the "Share Repurchase") at a price equal to the price per share that the Selling Shareholder will receive from its sale of Kosmos's common stock to the underwriter of the Offering. The Company intends to fund the Share Repurchase with cash on hand and other available sources of liquidity. Although the Share Repurchase will be conditioned upon, among other things, the closing of the Offering, the closing of the Offering will not be conditioned upon the closing of the Share Repurchase. The Share Repurchase has been unanimously approved by disinterested members of the Company's Board of Directors who are not affiliated with the Selling Shareholder.

Andrew G. Inglis, chairman and chief executive officer, said: "We are very pleased to come to an agreement with Warburg to help facilitate and accelerate a significant reduction in their position. We were able to take advantage of this unique opportunity and our strong balance sheet to re-purchase shares at an attractive price. In addition, this transaction further broadens our shareholder register and increases the company's free float."

The Offering is being made pursuant to an effective shelf registration statement, including a prospectus, filed by Kosmos with the U.S. Securities and Exchange Commission (the "SEC") on August 28, 2018. Before you invest, you should read the prospectus in that registration statement and other documents Kosmos has filed with the SEC for more complete information about Kosmos and the Offering.
