DALLAS, Nov. 02, 2026 (GLOBE NEWSWIRE) -- Kosmos Energy Ltd. (“Kosmos” or the “Company”) (NYSE/LSE: KOS) announced today its financial and operating results for the third quarter of 2026. For the quarter, the Company generated a net loss of $43 million, or $0.07 per diluted share. When adjusted for certain items that impact the comparability of results, the Company generated an adjusted net income⁽¹⁾ of $35 million, or $0.06 per diluted share for the third quarter of 2026.

THIRD QUARTER 2026 AND POST QUARTER END HIGHLIGHTS

• Net Production⁽²⁾: ~69,200 barrels of oil equivalent per day (boepd), up ~6% versus third quarter 2025 (~17% excluding Equatorial Guinea)
  
  
• Revenues: $410 million, or $71.39 per barrel of oil equivalent (boe) (excluding the impact of derivative cash settlements)
  
  
• Production expense: $102 million (or $17.72 per boe), a reduction in absolute production expenses of ~31% compared to third quarter 2025
  
  
• Capital expenditures: $85 million
  
  
• Jubilee 2025/26 drilling campaign completed with seven wells successfully drilled during the program
  
  
• Completed the Tiberius farm-down, securing a mix of upfront cash consideration, carry for future capital expenditure and future milestone payments
  
  
• Reduced net debt⁽¹⁾ by over $500 million through the end of the third quarter and are on track to achieve our 20% debt reduction target in 2026
  
  
• Successfully completed the $1.2 billion reserve-based lending (RBL) facility amendment and extension, further addressing near-term maturities
  
  

Commenting on the Company’s third quarter 2026 performance, Chairman and Chief Executive Officer Andrew G. Inglis said: “Kosmos continued to make meaningful progress during the third quarter against the four objectives we established at the beginning of the year: increase production, lower costs, reduce debt and advance our quality growth opportunities. Through a combination of strong operational execution, reduced costs, disciplined capital allocation and proactive financing, we continue to strengthen our business.

In Ghana, the 2025/26 Jubilee drilling campaign successfully delivered seven wells and demonstrated the continued quality of the infill opportunities of this midlife asset. At GTA, production continues to be strong with solid reservoir performance. Across the portfolio, we remain focused on maximizing value from our existing assets while investing selectively in growth opportunities with attractive returns.

Financially, 2026 continues to represent a year of significant progress for Kosmos. Since the beginning of the year, we have materially improved liquidity, reduced debt, extended maturities, lowered leverage and strengthened the overall credit profile of the company. With the RBL re-financing complete, we have further increased our financial resilience and will now look to address our 2028 bond maturities.

Looking ahead, our focus remains clear and we expect to make continued progress against our four strategic priorities, entering 2027 in a much stronger position with multiple catalysts across the portfolio to create additional value.”

FINANCIAL UPDATE

The Company generated net cash provided by operating activities of approximately $164 million and free cash flow⁽¹⁾ of approximately $90 million in the third quarter. Kosmos has now delivered three consecutive quarters of positive free cash flow with year-to-date free cash flow of $193 million, reflecting continued operational performance, higher realized pricing and disciplined capital spending. Kosmos exited the third quarter of 2026 with approximately $2.47 billion of net debt⁽¹⁾ and approximately $570 million of liquidity.

In October, Kosmos completed the amendment and extension of the RBL with a facility size and total commitments of $1.2 billion. The final maturity has been extended to April 2033. Following the significant reduction in debt year-to-date and $750 million currently drawn on the facility, there are no planned amortization payments until 2031.

With strong operational performance for the year and continued debt reduction, we are on track to achieve our ~20% net debt reduction target for 2026 with year-end net debt expected to be below $2.4 billion and leverage expected to fall towards 2.0x.

Net capital expenditure for the third quarter of 2026 was $85 million, in line with guidance. Full year 2026 capital expenditure guidance of approximately $350 million is unchanged.

Kosmos has continued to take advantage of higher oil prices to add further hedges for 2027. The Company has 8 million barrels of oil hedged for 2027 with an average floor of approximately $68/barrel and an average ceiling of approximately $84/barrel.

OPERATIONAL UPDATE

Production

Total net production⁽²⁾ in the third quarter of 2026 averaged approximately 69,200 boepd, in line with guidance. Sales for the third quarter of 2026 were approximately 62,400 boepd.

The Company exited the quarter in a net underlift position of approximately 1.1 mmboe.

Ghana

Production in Ghana averaged approximately 40,500 boepd net in the third quarter of 2026, which included gas production of approximately 6,800 boepd. 2.75 Jubilee cargo liftings took place in the third quarter, in line with guidance.

At Jubilee (38.6% working interest), oil production in the third quarter averaged approximately 84,500 bopd gross, approximately 17% higher than the second quarter. During the quarter, Kosmos and its partners completed the 2025/26 drilling campaign, which delivered seven successful infill wells. The final well in the program, a water injector, was drilled and completed during the third quarter. With the drilling activity in 2026 now concluded, the Company continues to work closely with the operator to drive operational excellence to mitigate decline ahead of the 2027/28 drilling campaign, including improved water injection performance, adding gas lift to the west side of the field, production system optimization and high FPSO uptime. Importantly, in September, the partnership secured the Noble Faye Kozack rig for the 2027/28 drilling program of up to 10 wells, which is expected to start in mid-2027.

At TEN (20.4% working interest), oil production averaged approximately 14,600 bopd gross for the third quarter, in line with expectations. Preparations continue for the ownership and operational transition of the FPSO to the partnership, scheduled for the first quarter of 2027, which is expected to drive a further reduction in operating costs for TEN production thereafter.

Mauritania and Senegal

Greater Tortue Ahmeyim ("GTA") continued to demonstrate stable operations during the third quarter, delivering cargos slightly ahead of guidance, while maintaining strong reservoir performance.

GTA production averaged approximately 14,600 boepd net during the quarter, or approximately 2.44 mtpa of LNG equivalent gross, reflecting warmer seasonal temperatures as previously guided. The partnership lifted 8.5 gross LNG cargos in the third quarter, slightly above guidance, bringing the total number of gross LNG cargos for the nine months ended September 30 to 27. Full year gross LNG cargo liftings are expected to be at the upper end of the 32-36 guidance range. The third gross condensate cargo of the year was lifted by Kosmos and the national oil companies of Mauritania and Senegal at the beginning of the fourth quarter, with timing slightly impacted by weather.

Work continues to advance domestic gas initiatives and Phase 1+ development planning, with several positive engagements with our host governments and partners in recent weeks regarding the future development of the resource.

In Senegal, Réseau Gazier du Sénégal, the operator of the gas pipeline, reported that the first phase of the onshore pipeline (the "Northern Segment") to connect the GTA hub to the 230 megawatt Gandon power plant is over 25% complete as of October 2026.

Gulf of America

Production in the Gulf of America averaged approximately 14,100 boepd net (~83% oil) during the third quarter, in line with guidance, reflecting continued strong performance from the Company's operated assets, partially offset by host facility downtime.

In the fourth quarter, Gulf of America production is expected to be impacted by planned Delta House platform maintenance (Odd Job host facility), a workover on the Kodiak-1 well and downtime associated with Hurricane Isaias, and has been reflected in the Company's fourth quarter guidance.

On the Kosmos-operated Tiberius project, Kosmos successfully completed a highly competitive farm out process in July, with Navitas becoming a 33.33% partner in the project alongside Kosmos (33.34%) and Occidental (33.33%, as well as an owner and operator of the host facility, Lucius). The consideration for the farm down was a mix of upfront cash, carry for future development capital expenditure, and future milestone payments, preserving significant future upside and reducing near-term capital requirements. The carry is expected to cover Kosmos' spend on the project through 2026 and the first half of 2027.

Kosmos continues to mature several high-return growth opportunities, including Trailblazer, while maintaining a disciplined approach to capital allocation. Trailblazer (~200 mmboe gross resource) is the first exploration well to be drilled through the exploration alliance with Shell announced earlier in the year. Drilling is expected to commence in the first half of 2027. In the event of success, Trailblazer could be tied back into Shell's nearby Appomattox platform with Kosmos designated as development operator.

(1) A Non-GAAP measure, see attached reconciliation of non-GAAP measure. Net debt excludes $63.9 million TEN FPSO finance lease liability. For purposes of the debt cover ratio calculation under the RBL Facility, the finance lease liability is included in net debt.
(2) Production means net entitlement volumes. In Ghana and Mauritania and Senegal this means those volumes net to Kosmos' working interest or participating interest and net of royalty or production sharing contract effect. In the Gulf of America, this means those volumes net to Kosmos' working interest and net of royalty.

Non-GAAP Financial Measures

EBITDAX, Adjusted net income (loss), Adjusted net income (loss) per share, free cash flow, and net debt are supplemental non-GAAP financial measures used by management and external users of the Company's consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines EBITDAX as Net income (loss) plus (i) exploration expense, (ii) depletion, depreciation and amortization expense, (iii) equity based compensation expense, (iv) unrealized (gain) loss on commodity derivatives (realized losses are deducted and realized gains are added back), (v) (gain) loss on sale of oil and gas properties, (vi) interest (income) expense, (vii) income taxes, (viii) debt modifications and extinguishments, (ix) doubtful accounts expense and (x) similar other material items which management believes affect the comparability of operating results. The Company defines Adjusted net income (loss) as Net income (loss) adjusted for certain items that impact the comparability of results. The Company defines free cash flow as net cash provided by operating activities less Oil and gas assets, Other property, and certain other items that may affect the comparability of results and excludes non-recurring activity such as acquisitions, divestitures and National Oil Company ("NOC") financing. NOC financing refers to the amounts funded by Kosmos under the Carry Advance Agreements that the Company has in place with the national oil companies of each of Mauritania and Senegal related to the financing of the respective national oil companies’ share of certain development costs at Greater Tortue Ahmeyim. The Company defines net debt as total long-term debt less cash and cash equivalents and total restricted cash.

We believe that EBITDAX, Adjusted net income (loss), Adjusted net income (loss) per share, free cash flow, Net debt and other similar measures are useful to investors because they are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in the oil and gas sector and will provide investors with a useful tool for assessing the comparability between periods, among securities analysts, as well as company by company. EBITDAX, Adjusted net income (loss), Adjusted net income (loss) per share, free cash flow, and net debt as presented by us may not be comparable to similarly titled measures of other companies.

This release also contains certain forward-looking non-GAAP financial measures, including free cash flow. Due to the forward-looking nature of the aforementioned non-GAAP financial measures, management cannot reliably or reasonably predict certain of the necessary components of the most directly comparable forward-looking GAAP measures, such as future impairments and future changes in working capital. Accordingly, we are unable to present a quantitative reconciliation of such forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures. Amounts excluded from these non-GAAP measures in future periods could be significant.
