Kosmos Energy Posts Q4 Loss but Targets 15% Production Growth and Debt Reduction in 2026

Kosmos Energy’s Q4 2025 in focus – loss-heavy quarter, but 2026 growth engines are revving

Kosmos Energy has posted a bruising GAAP net loss for Q4 2025, but the operational story looks better than the headline. The company is leaning on Ghana’s Jubilee field and the Greater Tortue Ahmeyim (GTA) LNG project to drive a forecast 15% production uplift in 2026, alongside a plan to trim operating costs by around 20% and reduce debt by at least 10% by year-end.

Below I break down what happened, why the loss is not as scary as it looks, and what to watch in 2026.

Quarterly results – what the numbers say

Jargon check: boe stands for barrels of oil equivalent, a way to bundle oil, gas and NGLs into one number. Underlift means Kosmos sold less than it produced, creating a timing benefit for future sales.

Why the big GAAP loss – and why adjusted results matter here

The $377 million net loss was driven by non-cash items and clean-up costs rather than core operations. In Q4, Kosmos wrote off $144 million of suspended well costs at Yakaar-Teranga in Senegal and booked ~$178 million of impairments in the Gulf of America, largely related to Winterfell. Interest expense also remains chunky at $58.8 million in the quarter.

On an adjusted basis, which removes these one-off items, the loss narrows to $78 million. That still reflects start-up costs at GTA and softer realised prices versus last year, but it paints a more representative picture of the underlying business.

Operations – Jubilee and GTA are doing the heavy lifting

Ghana – Jubilee growth is back on track

• Jubilee oil averaged ~59,100 bopd gross in Q4, with a planned slowdown in base decline.
• The J74 producer well came online in January at ~13,000 bopd gross, lifting current Jubilee output to above 70,000 bopd.
• J75 is drilled with ~40 metres of net pay and due online around end Q1. Four further wells are slated for 2026 – three producers and one water injector.
• Ghana production averaged ~31,100 boepd net in Q4, with two cargos lifted in the quarter and a third in early 2026.

Significantly, Ghana’s Jubilee and TEN licences have been extended to 2040. That underpins up to $2 billion of incremental investment and increases Kosmos’ 1P and 2P reserves at Jubilee.

Mauritania & Senegal – GTA ramp-up and costs coming down

• GTA Phase 1 averaged ~14,200 boepd net in Q4, reaching nameplate of ~2.7 mtpa equivalent in December. Year-to-date 2026 production is ~2.9 mtpa equivalent.
• ~8.0 gross LNG cargos lifted in Q4, 18.5 in 2025, plus the first condensate cargo sold at a small discount to Brent. 2026 gross LNG cargos are expected to roughly double year-on-year.
• Net operating costs per boe at GTA are expected to fall by more than 50% in 2026, helped by the FPSO refinancing and a lower-cost operating model.

Jargon check: mtpa is million tonnes per annum for LNG. FPSO is a floating production, storage and offloading vessel.

Strategically, the partnership is now turning to GTA Phase 1+ to use existing kit for domestic gas sales in Senegal and Mauritania, with heads of terms expected in 2026. Kosmos is also working with Petrosen to withdraw from Yakaar-Teranga after failing to land a partner on attractive terms.

Gulf of America and Equatorial Guinea – portfolio shaping

• Gulf of America averaged ~16,900 boepd net in Q4, slightly below guidance after facility downtime. Tiberius is progressing towards FID in H1 2026 with a farm-down planned. A new exploration alliance with Shell covers ten Norphlet trend blocks, including the 2027 Trailblazer prospect.
• Equatorial Guinea averaged ~16,200 bopd gross and ~5,700 bopd net in Q4. Kosmos has agreed to sell its 40.375% interest in Ceiba and Okume to Panoro Energy for up to $220 million, with close targeted mid-2026.

Reserves and reliability – longer runway, but mixed replacement

• Year-end 1P reserves ~250 mmboe – around a 10-year reserve life – with ~90% replacement in 2025, or ~120% excluding Equatorial Guinea disposal assets.
• 2P reserves ~500 mmboe – roughly a 20-year reserve life – but a replacement rate of approximately (18)% due to minor downward revisions including in Equatorial Guinea.

Jargon check: 1P reserves are proved reserves with high confidence. 2P adds probable reserves. The increases tied to the Ghana licence extension are a tangible positive for long-term value.

Costs, capex and hedging – levers for cash flow in 2026

• Production costs were $26.04/boe in Q4, or $22.24/boe excluding GTA’s $50.9 million of start-up-heavy costs. Management targets a ~20% year-on-year reduction in total operating costs in 2026, with GTA unit costs down by more than 50%.
• FY25 capex was $292 million, about 25% below the initial plan. FY26 capex is guided at around $350 million, with roughly two thirds going to fast-payback Jubilee drilling.
• Hedging provides a floor – 8.5 million barrels in 2026 at roughly $66/bbl and 2.0 million barrels in 2027 at ~$60/bbl. Note there are sold calls and sold puts in 2026 that can cap some upside and add obligations if prices fall sharply.

Balance sheet – refinancing done, debt reduction next

Kosmos has been active on the liability side. The company redeemed its 2026 notes using a Shell-backed term facility, then issued $350 million of senior secured bonds in the Nordic market to repurchase part of the 2027 notes and repay $100 million on the RBL. RBL lenders also amended the debt cover ratio for the next two tests to accommodate GTA start-up costs.

Net debt sat at approximately $3.0 billion at year-end with liquidity of around $342 million. Management says it has raised $600 million in new capital in recent months and is targeting at least 10% debt reduction by end-2026, helped by free cash flow and the Equatorial Guinea sale proceeds.

Jargon check: RBL is a reserve-based lending facility secured on producing assets.

2026 guidance – what to expect

• Production: 70,000 – 78,000 boepd for FY26, with Q1 at 72,000 – 76,000 boepd. Management expects around 15% year-on-year growth, driven by Jubilee wells and a full year of GTA.
• Opex: $20.00 – $22.00 per boe for FY26.
• DD&A: $18.00 – $20.00 per boe.
• G&A: ~£75 million equivalent in USD terms per guidance of ~$75 million, ~65% cash.
• Net interest expense: ~$240 – $260 million.
• Exploration expense: $10 – $30 million, excluding leasehold impairments and dry holes.
• Capex: around $350 million.

My take – the good, the bad, and the swing factors

Positives

• Operational momentum is clear – Jubilee back above 70,000 bopd gross and GTA at or above nameplate with more cargos coming in 2026.
• Material cost-down in flight, especially at GTA, should improve margins as volumes rise.
• Ghana licence extensions to 2040 add longevity and support reserve growth and future drilling.
• Balance sheet risk is better managed after refinancing, with a credible plan to cut absolute debt in 2026 and monetisation of non-core Equatorial Guinea.
• Hedging provides downside protection in a choppy oil market.

Watch-outs

• Q4 loss underlines that interest costs and impairments are a real drag – FY25 interest and other financing costs were $223.4 million, and FY26 interest is guided even higher.
• GTA execution on cost reduction is essential – the unit cost step-down needs to land to hit the ~20% opex reduction target.
• Reserves replacement is mixed – 1P strong, 2P softer at approximately (18)% – and the Equatorial Guinea sale removes some producing barrels pending reinvestment.
• Sold options in the hedge book can limit upside and add obligations at certain price points.

Bottom line – set up for a better 2026 if delivery continues

The quarter’s GAAP loss is ugly, but largely about clearing the decks. The investment case for 2026 rests on higher production from Jubilee and a full-year GTA, lower unit costs, and steady deleveraging. If Kosmos delivers on the plan – 15% production growth, ~20% opex down, at least 10% debt reduction – the equity story should improve from here.

Key catalysts to watch: Jubilee well delivery through 2026, evidence of GTA cost reductions flowing through the P&L, closing of the Equatorial Guinea sale mid-year, and progress on Tiberius FID and the Ghana drilling campaign.
