KOSMOS ENERGY ANNOUNCES FIRST GAS AT THE GREATER TORTUE AHMEYIM

LNG PROJECT IN MAURITANIA AND SENEGAL

DALLAS, Texas, January 2, 2025 - Kosmos Energy (NYSE/LSE: KOS) notes the announcement today from bp plc (operator) that first gas production has been achieved at the Greater Tortue Ahmeyim (GTA) liquefied natural gas (LNG) project offshore Mauritania and Senegal.  

On December 31, 2024, gas from the first phase of GTA started to flow from wells to the floating production storage and offloading (FPSO) vessel ahead of delivery to the floating LNG vessel for liquefaction. Once fully commissioned, GTA Phase 1 is expected to produce around 2.3 million tonnes of LNG per annum (mtpa) with the floating LNG vessel nameplate capacity of approximately 2.7 mtpa.

First gas is a key milestone for the partnership and the governments of Mauritania and Senegal and an important step for the countries to become a strategic LNG production hub in West Africa. First LNG production is expected to follow shortly with the first LNG cargo expected in the first quarter of 2025, which is when we start to recognize revenue from the project.

Commenting on first gas production at GTA, Chairman and Chief Executive Officer Andrew G. Inglis said: "Achieving first gas sets the stage for us to ramp up production and reach the ~90,000 boepd production target we set two years ago. With our key growth projects largely delivered and capex falling, Kosmos is well positioned going into 2025. The company remains focused on disciplined capital allocation and the generation of free cash flow that enables us to pay down debt, reduce leverage to less than 1.5x, and enhance the financial resilience of the company."

When used in this press release, the words "anticipate," "believe," "intend," "expect," "plan," "will" or other similar words are intended to identify forward-looking statements.

Management does not provide a reconciliation for forward looking non GAAP financial measures where it is unable to provide a meaningful or accurate calculation or estimation of reconciling items and the information is not available without unreasonable effort. This is due to the inherent difficulty of forecasting the occurrence and the financial impact of various items that have not yet occurred, are out of our control or cannot be reasonably predicted. For the same reasons, management is unable to address the probable significance of the unavailable information. Forward looking non GAAP financial measures provided without the most directly comparable GAAP financial measures may vary materially from the corresponding GAAP financial measures.
