Kosmos Energy Ltd. reports a detailed annual update as a deepwater oil and gas producer with assets in Ghana, Equatorial Guinea, Mauritania, Senegal, and the Gulf of America. For 2025, total sales volumes were 22.4 MMBoe with revenue of $1,288,352 thousand and average realized oil price of $66.89 per barrel.
The company achieved first LNG from the Greater Tortue Ahmeyim project in early 2025, exporting 18.5 gross LNG cargos and one condensate cargo during the year, and the Gimi FLNG reached nameplate capacity around 3.0 million tonnes per annum in December. Proved reserves at year-end 2025 were 249 MMBoe, including 120 MMBbl of liquids and 770 Bcf of natural gas.
Kosmos extended its key Ghana licenses for the Jubilee and TEN fields to 2040, enabling additional drilling, and continued to develop Gulf of America discoveries such as Winterfell and Tiberius. Liquidity was approximately $342 million as of December 31, 2025, supported by an active hedging program and a focus on leverage reduction and ESG targets, including maintaining operated Scope 1 and 2 carbon neutrality and reducing Scope 1 equity emissions.
Kosmos Energy Ltd. reported weak fourth quarter and full-year 2025 results, driven by large non-cash charges and higher costs. For Q4 2025, the company posted a net loss of $377 million, or $0.79 per diluted share, and an adjusted net loss of $78 million, or $0.16 per share. Full-year 2025 net loss was $699.8 million, or $1.47 per share, compared with net income of $189.9 million in 2024, as revenues fell to $1.29 billion from $1.68 billion and impairments and exploration costs rose sharply. Q4 net production averaged about 67,900 boepd, with strong contributions from the Greater Tortue Ahmeyim LNG project and Ghana’s Jubilee field, and year-end 1P and 2P reserves were roughly 250 mmboe and 500 mmboe, implying reserve lives of around 10 and 20 years. Kosmos exited 2025 with approximately $3.0 billion of net debt and liquidity of about $342 million, but it has refinanced near-term notes, added oil price hedges, agreed to sell its Equatorial Guinea interests for up to $220 million, and guided to 2026 production growth of around 15%, operating cost reductions of about 20%, and at least 10% debt reduction by year-end.
Kosmos Energy Ltd. has agreed to sell its 40.375% non-operating working interest in the Ceiba Field and Okume Complex offshore Equatorial Guinea to Panoro Energy for up to $219.5 million. The consideration includes an upfront $180 million cash payment, subject to adjustments, plus contingent payments of up to $39.5 million tied to production and oil price thresholds through 2029.
The deal monetizes later-life, non-core production assets and is intended to strengthen the balance sheet. Kosmos plans to use the proceeds to reduce borrowings under its reserves-based lending credit facility and expects about $100 million in capital and administrative cost savings over the two years following completion. The transaction has Government of Equatorial Guinea approval and is expected to close around mid-2026, pending CEMAC customary approval.
