First LNG at GTA

KOSMOS ENERGY ANNOUNCES FIRST LNG AT THE GREATER TORTUE AHMEYIM

PROJECT IN MAURITANIA AND SENEGAL

DALLAS, Texas, February 10, 2025 - Kosmos Energy (NYSE/LSE: KOS) today announces that first liquified natural gas (LNG) production has been achieved at the bp-operated Greater Tortue Ahmeyim (GTA) LNG project, offshore Mauritania & 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 as part of the commissioning process. At the FPSO, gas is being processed to remove any condensate, water and impurities ahead of delivery to the floating LNG vessel for liquefaction.

Gas has now been delivered to the floating LNG vessel and liquefaction has commenced. The liquefaction of gas into LNG is when Kosmos starts to recognize gas entitlement production from the project in its quarterly statements. In addition, bp has given notice to the offtaker (bp gas marketing ltd.) for an LNG carrier to arrive later this quarter to export the first LNG cargo. Lifting of the first LNG cargo is when Kosmos starts to recognize revenue and generate cash flow from the project.

Commenting on first LNG production at GTA, Chairman and Chief Executive Officer Andrew G. Inglis said: "First LNG is another major milestone for Kosmos, the GTA partnership and the governments of Mauritania and Senegal. We are looking forward to the accelerated ramp-up of LNG production and the first LNG cargo lifting during the first quarter."

Although Kosmos believes 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 Kosmos. 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. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of Kosmos, which may cause actual results to differ materially from those implied or expressed by the forward-looking statements. Further information on such assumptions, risks and uncertainties is available in Kosmos' Securities and Exchange Commission ("SEC") filings.

All forward-looking statements are qualified in their entirety by this cautionary statement.

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.
