First 2025 Jubilee well onstream with better net pay than expected
Strong strategic momentum with realisation of $300 million Gabon proceeds
Focused on delivering our key strategic priority of refinancing our capital structure
Tullow Oil plc ("Tullow"), the independent oil and gas exploration and production group ("Group"), announces its Half Year Results for the six months ended 30 June 2025. Details of a management presentation and webcast that will be held at 9:00 BST today are available on the last page of this announcement or visit the Group's website: www.tullowoil.com
Richard Miller, Chief Financial Officer and Interim Chief Executive Officer, Tullow Oil plc, commented:
"Our 2025 strategic priorities remain clear: refinancing our capital structure, optimising production, increasing reserves, and completing the sale of our Kenyan assets, having already realised $300 million proceeds from the sale of our portfolio of assets in Gabon.
"In Ghana we have already taken actions to address the recent underperformance at Jubilee, with further optimisation potential identified. We have recommenced drilling and have successfully completed and brought onstream the first of two planned 2025 production wells at Jubilee, with better than expected net pay during drilling. The high quality 4D seismic data acquired at the start of the year is now being used to generate improved models that will directly inform the well-planning process and will be further supported with the capture of an Ocean Bottom Node (OBN) seismic survey in the fourth quarter this year.
"We achieved a key milestone by signing a MoU in Ghana to extend our production licences for both Jubilee and TEN to 2040, which is expected to increase reserves and unlock significant value from these fields.
"In the second half of the year we are focussed on refinancing our capital structure, production optimisation activities and continuing to optimise our cost base, which combined with the progress in the first half of the year will help unlock Tullow's intrinsic value."
2025 FIRST HALF RESULTS
· First half Group working interest oil and gas production 50.0 kboepd (1H24: 63.7 kboepd). Excluding Gabon, 40.6 kboepd (1H24: 53.5 kboepd).

· Free cash flow1 of $(188) million in 1H25 (1H24: $(126) million), in line with expectations based on timing of tax payments, lifting schedule and costs associated with Jubilee maintenance in 1H25.
· Net debt1 at 30 June 2025 of $1.6 billion (30 June 2024: $1.7 billion); cash gearing of 1.9x net debt/EBITDAX1 (30 June 2024: 1.4x); liquidity headroom of $0.2 billion (30 June 2024: $0.7 billion). Excluding Gabon, cash gearing of 2.1x net debt/EBITDAX (30 June 2024: 1.6x).
strategic priorities
· The first half of 2025 has seen significant progress towards delivery of our strategic priorities for the year to realise Tullow's potential, including:
- On 29 July, Tullow completed the sale of Tullow Oil Gabon SA for a total cash consideration of $300 million net of tax.
- On 21 July, Tullow entered into a sale and purchase agreement for the sale of Tullow Kenya BV for a cash consideration of at least $120 million. Completion and receipt of the first two milestone payments, totalling $80 million, are expected during 2025.
- On 4 June, Tullow and its JV partners announced a Memorandum of Understanding (MoU) with the Government of Ghana to extend the West Cape Three Points (WCTP) and Deep Water Tano (DWT) licences to 2040; the MoU includes a commitment to work to increase gas supply to c.130 mmscf/d and a guaranteed reimbursement mechanism for gas sales. As a result of the licence extensions the JV partners expect to realise a material increase in gross 2P reserves.
- In January the International Chamber of Commerce Tribunal determined that Branch Profit Remittance Tax (BPRT) in Ghana is not appliable to Tullow Ghana and therefore it is not liable to pay the $320 million assessment.
2025 FULL YEAR OUTLOOK
· 2025 Group working interest production guidance is expected to average 40-45 kboepd, including c.6 kboepd of gas, reflecting the sale of the Gabonese assets effective from the start of the year.
· Full year capex and decommissioning guidance, both updated to reflect the Gabonese sale, of c.$185 million and c.$20 million, respectively.
· Ghana drilling campaign recommenced with the J72-P well, the first of two Jubilee production wells in 2025, which was brought onstream at the end of July having encountered better than expected net pay during drilling operations.
· Interpretation of the 4D seismic data acquired in the first quarter continues, with a further four firm Jubilee wells planned for 2026.
· Cost base optimisation savings of c.$10 million expected to reduce 2025 annual net G&A to $40 million, with Group targeted savings of c.$50 million over the next three years compared to 2024.
· Full year free cash flow guidance is adjusted to $300 million at $65/bbl, reflecting 1H25 Jubilee production performance resulting in one lifting moving into 2026. Guidance is inclusive of $380 million of disposal proceeds, $35 million of 2024 Gabonese cash taxes paid in 1H25 which are not reimbursed through the transaction and c.$50 million of overdue gas payments in Ghana.
· Year-end net debt guidance is unchanged at c.$1.1 billion with gearing of c.1.3x (net debt/EBITDAX1).
· Following completion of the sale of Tullow Oil Gabon SA, Tullow applied part of the proceeds to repay in full and simultaneously cancel the $150 million Revolving Credit Facility (RCF).
· Tullow remains focused on further deleveraging and reaching net debt of less than $1 billion and cash gearing of less than 1x in the near term.
Operational update
Production
In the first six months of 2025, Group production averaged 50.0 kboepd (40.6 kboepd excluding Gabon), including 7.1 kboepd of gas. 2025 Group production guidance is expected to be at the lower end of the 40-45 kboepd range (previously 50-55 kboepd), reflecting the removal of Gabonese production from the start of the year and including c.6 kboepd of gas.
Ghana
During the first six months of the year, operational efficiency remained high, with average facility uptime across the Ghana FPSOs at 97% and a combined average oil production rate of c.32.8 kbopd net and an average gas production rate of 6.2 kboepd net.
Gross oil production from the Jubilee field averaged 60.9 kbopd (net: 23.7 kbopd) in the first half of the year, inclusive of a 15 day planned maintenance shutdown conducted safely and on budget. During the first half of 2025, Jubilee has been affected by higher than expected water cut from certain wells, which has impacted riser stability on the eastern side of Jubilee. Riser base gas lift has now been introduced on the east side of the field, which restored and stabilised production in June. Riser base gas lift for the western side of Jubilee, which will provide further uplift to production and reserves, has been sanctioned and will be implemented in the coming years.
Voidage replacement was greater than 100% in the first half of the year, but water injection levels were lower than expected due to planned maintenance taking longer than expected and a fault with the sea water lift system. Tullow anticipates being able to restore water injection rates closer to capacity of 300 kbw/d in the second half of 2025 to provide increased pressure support and reduce declines. Additionally, we expect a further uplift in production from the J72-P well, which encountered better than expected net pay and was brought onstream in July.
When the rig recommences drilling in the fourth quarter of the year, after a break for maintenance, the next well is planned to be a Jubilee producer (J73-P), to come onstream around the end of the year. A further four firm Jubilee wells are then planned for 2026. Processing of the 4D seismic, shot in the first quarter, is currently ongoing and will help validate the locations for the later wells in the campaign. Tullow will further enhance this data set with the capture of an Ocean Bottom Node (OBN) seismic survey in the fourth quarter of 2025, which will underpin infill drilling across Jubilee and TEN.
Gross oil production from the TEN fields averaged 16.4 kbopd (net: 9.0 kbopd) in the first half of the year. This was above expectations supported by opening a previously shut-in production interval in Enyenra and water injection optimisation activities. The TEN FPSO flare tip was replaced in May, which has allowed a further c.50% reduction in routine flaring from July 2025 onwards.
As part of the Memorandum of Understanding (MoU) relating to the extension of the WCTP and DWT licences in Ghana, a number of principles are included that underpin the continued development of both TEN and Jubilee. These include a commitment to work to increase the supply of gas to c.130 mmscf/d (from current level of c.100 mmscf/d), a reduced gas price for Jubilee associated gas, and a guaranteed reimbursement mechanism for gas sales. The MoU describes the intended further development plans for Jubilee, which includes the right to drill up to 20 additional wells in the Jubilee field, representing investment of up to $2 billion in Ghana over the life of the licences. As a result of the licence extensions to 2040 the JV partnership expects to realise a material increase in gross 2P reserves.
Non-operated and exploration portfolios
Tullow completed the $300 million sale of its non-core Gabon assets to the Gabon Oil Company on 29 July 2025.
In Côte d'Ivoire, Tullow continues to work with the operator of the Espoir field to optimise the strategy for the asset point forwards.
As part of continued portfolio rationalisation, the Group has taken the decision to exit exploration licences in Cote d'Ivoire (CI-524 and CI-803) and the MLO 114 and MLO 119 licences in Argentina. Tullow continues to focus efforts on infrastructure-led exploration activities in Ghana.
Kenya
Tullow entered into a sale and purchase agreement for the sale of its Kenya assets to Auron Energy E&P Limited, an affiliate of Gulf Energy Limited on 21 July 2025 for a total consideration of at least $120 million. In addition, Tullow will be entitled to royalty payments subject to certain conditions and retains a no-cost back-in right for a 30% participation in future development phases. The company expects completion with receipt of the first two payments, totalling $80 million, during 2025.
Reserves and resources
Tullow will publish its 1H25 reserves report in September and expects a reduction based on the incorporation of first half production data and field underperformance at Jubilee. The recent sanction of riser base gas lift, the potential uplift associated with new incremental drilling targets and licence extensions are expected to offset the reduction in due course.
Sustainability
Our sustainability approach focuses on three core themes - People, Climate and Nature - which are aligned with the issues that are most significant to our business, our stakeholders and the relevant broader UN Sustainable Development Goals (SDGs). These sustainability themes are underpinned by robust corporate governance and responsible business conduct, both of which continued to be deemed material from an impact and financial standpoint.
Care for people
Tullow continues to prioritise safe operations and finished the first half 2025 with four medical treatment cases.
Tullow continues to work closely with local suppliers to drive local content and strengthen human rights due diligence through increased engagement, support, and training.
Achieve Net Zero
Tullow continued to make progress on its Net Zero by 2030 (Scope 1 and 2) target during the first half of 2025. Tullow completed engineering works in the first six months of 2025 to progress workstreams to eliminate routine flaring. To address hard-to-abate residual emissions, Tullow is progressing its nature based carbon offset project with the Ghana Forestry Commission (FC) that is expected to deliver first offsets by the end of 2026. The FC has conducted extensive community engagement, begun tree planting and initiated an environmental and social impact assessment in the first half of 2025.
Respect the environment
In April 2025, Tullow published its inaugural nature disclosure which aligns with the recommendations of the Taskforce on Nature-related Financial Disclosures (TNFD). The report is based on the outcomes of the assessment of the biodiversity baseline completed in 2024 and focused on Ghana.
Governance
As previously announced, Sheila Khama, Independent Non-Executive Director has stepped down from the Board with effect from 1 August 2025, to focus on her other professional commitments and roles outside of Tullow.
Revenue
Sales oil volumes
During the period, there were 30,200 boepd (1H 2024: 45,300 boepd) of liftings. The decrease is mainly due to fewer liftings in Ghana with 5 in Jubilee (1H 2024: 7) and 1 in TEN (1H 2024: 2).
Realised oil price ($/bbl)
The Group's realised oil price after hedging for the period was $69.7/bbl (1H 2024: $77.0/bbl) and before hedging $71.4/bbl (1H 2024: $84.0/bbl). Lower oil prices and lower hedged volumes compared to 1H 2024 have resulted in a lower hedge loss which decreased total revenue by $10 million in 1H 2025 (1H 2024: decrease of $58 million).
Gas sales
Included in Total Revenue of $411 million is gas sales of $30 million (1H 2024: $29 million) of which $27 million (1H 2024: $25 million) relates to Ghana. During the period, Tullow exported 17,342 mmscf (gross) of gas at an average price of $3.04/mmbtu in Ghana (1H 2024: 18,148 mmscf, $2.95/mmbtu).
Cost of Sales
Underlying cash operating costs
Underlying cash operating costs amounted to $108 million; $14.6/boe (1H 2024: $87 million; $8.9/boe). This consists of Ghana $88 million ($12.4/boe), Cote d'Ivoire $11 million ($48.1/boe) and Corporate $8 million. The increase is primarily driven by Jubilee shutdown and FPSO Class related maintenance costs in the current period. Routine operating costs are largely consistent with prior period.
Depreciation, depletion, and amortisation
DD&A charges before impairment on production and development assets amounted to $159 million; $21.6/boe (1H 2024: $186 million: $19.1/boe). This decrease in DD&A is mainly attributable to lower Jubilee field production compared to 1H 2024.
Underlift/Overlift and oil stock movements
The Group had an underlift compared to an overlift expense in the comparative period. The change was due to fewer liftings in Ghana in the current period resulting from lower oil production volumes.
Administrative expenses
Administrative expenses of $23 million (1H 2024: $31 million) have decreased against the comparative period mainly due to reduction in employee related expenses and professional fees, partially offset by an adverse movement in the foreign exchange rate. Full year forecast administrative costs are expected to be lower than prior year at c.$40 million. With continued focus on reducing G&A costs and rationalisation of the organisation following the simplification of the business, the Group is targeting savings of c.$50 million over the next three years compared to 2024.
Impairment of property, plant and equipment
The Group recognised a net impairment charge on PP&E of $39 million in the first half of 2025 (1H 2024: Net impairment reversal of $2 million), mainly driven by a $35 million impairment charge on TEN field from lower oil price assumptions.
Net financing costs
Net financing costs for the period were $139 million (1H 2024: $140 million). Lower net interest expense on obligations under leases was offset by debt arrangement fees incurred in 2025 and a reduced interest income. Interest on borrowings was in line with prior period as savings due to bond repayments were offset by interest on additional drawdown of borrowings.
A reconciliation of net financing costs is included in note 9.
Taxation
The overall adjusted net tax expense of $30 million (1H 2024: $148 million) primarily relates to tax charges in respect of the Group's production activities in West Africa, reduced by deferred tax credits associated with UK decommissioning assets, exploration write-offs and impairments.
Based on a loss before tax for the first half of the year of $50 million (1H 2024: profit before tax of $254 million), the effective tax rate (ETR) is (60.9)% (1H 2024: 58.4%). After adjusting for non-recurring amounts related to exploration write-offs, disposals and impairments, the Group's adjusted tax rate is 7,088.6% (1H 2024: 58.8%). In the UK, there is net interest and hedging expenses of $77 million (1H 2024: $123 million), however, there is no UK tax benefit as in previous periods.
The Group has applied the exception to recognising and disclosing information about deferred tax assets and liabilities relating to Pillar Two income taxes. The Group has not recorded any exposure to Pillar Two income taxes in those jurisdictions where the safe harbour thresholds are not met based on the latest available forecast data.
Adjusted EBITDAX
Adjusted EBITDAX for the year was $768 million (1H 2024: $1,083 million). The decrease in the period was mainly driven by lower revenue.
(Loss)/Profit for the year from continuing activities and (loss)/earnings per share
The loss for the year after tax from continuing activities amounted to $80 million (1H 2024: $106 million profit). The loss after tax was driven mainly by lower revenue, higher impairment charge and restructuring costs, offset by lower income tax expense in the current year. Basic loss per share was 5.5 cents (1H 2024: 7.3 cents earnings per share).
Capital Investment
Capital expenditure amounted to $103 million (1H 2024: $157 million) out of which $100 million was invested in production and development activities with a $63 million spend in Ghana (1H 2024: $117 million), $24 million in Gabon (1H 2024: $25 million), $11 million in Cote d'Ivoire (1H 2024: $5 million) and $2 million in Kenya (1H 2024: $4 million). $53 million of capital investment related to Jubilee (1H 2024: $108 million), mainly comprising $34 million of drilling costs (1H 2024: $96 million). Investment in exploration and appraisal activities was $3 million (1H 2024: $6 million).
The Group's 2025 capital expenditure guidance excluding Gabon is c.$185 million which will comprise Ghana of c.$160 million, Cote d'Ivoire of c.$15 million, Kenya and exploration spend of c.$10 million.
Decommissioning
Decommissioning expenditure was $1 million in the first half of 2025 (1H 2024: $9 million), and $12 million of cash provisioning for future decommissioning in Ghana (1H 2024: $nil). The Group's decommissioning guidance for 2025 is revised to c.$20 million, with expenditure in the second half of the year relating to the UK and Mauritania.
Derivative financial instruments
Tullow has a material hedge portfolio in place to protect against commodity price volatility and to ensure the availability of cash flow for re-investment in capital programmes that are driving business delivery.
At 30 June 2025, Tullow's hedge portfolio provides downside protection for c.70% of forecast production entitlements in the second half of 2025 with c.$60/bbl weighted average floors across all hedging instruments; for the same period, c.20% of forecast production entitlements is capped at weighted average sold calls of c.$89/bbl. A second tier of capped upside exists through three-way collars on c.25% of the total hedged volume with weighted average sold calls of $84/bbl, however, potential hedging losses on three-way collars are limited to a $10/bbl range due to the presence of purchased calls, allowing re-participation in the upside if oil prices rise above $94/bbl on a weighted average basis. Hedging ratios reflect the portfolio post-Gabon asset sale.
For 1H 2026, Tullow's hedge portfolio provides downside protection for c.15% of forecast production entitlements with c.$57/bbl weighted average floors, while c.10% is capped predominately with collars with weighted average sold calls at c.$76/bbl.
No hedges were in place for 2H 2026 as at 30 June 2025. All financial instruments that are initially recognised and subsequently measured at fair value have been classified in accordance with the hierarchy described in IFRS 13 Fair Value Measurement. Fair value is the amount for which the asset or liability could be exchanged in an arm's length transaction at the relevant date. Where available, fair values are determined using quoted prices in active markets (Level 1). To the extent that market prices are not available, fair values are estimated by reference to market-based transactions or using standard valuation techniques for the applicable instruments and commodities involved (Level 2).
All of the Group's derivatives are Level 2 (2024: Level 2). There were no transfers between fair value levels during the year.
At 30 June 2025, the Group's derivative instruments had a net negative fair value of $4 million (1H 2024: net negative $32 million).
Borrowings
On 1 March 2025, the Group repaid in full its Senior Notes. The principal repayment of $493 million and accrued interest to maturity were funded from a combination of drawing down the remaining balance of $270 million under the Glencore Facility and cash on balance sheet.
On 29 April 2025, the Group made a drawdown under its Revolving Credit Facility (RCF) to manage near-term working capital.
On 15 May 2025, the Group made the annual prepayment of $100 million of the Senior Secured Notes due 2026.
On 21 May 2025, the Group entered into an extension of its RCF to 31 October 2025 at reduced commitments of $150 million. On 29 July 2025, the Group repaid and cancelled in full the $150 million RCF, see note 24.
As at 30 June 2025, the Group's total drawn debt reduced to $1,835 million, consisting of $1,285 million nominal value Senior Secured Notes due in May 2026, $400 million outstanding under the Glencore facility and $150 million outstanding under the RCF.
Management regularly reviews options for optimising the Group's capital structure and may seek to refinance, retire or purchase any of its outstanding debt from time to time through new debt financings and/or cash purchases or exchanges in the open market, privately negotiated transactions or otherwise.
Credit Ratings
The Group maintains credit ratings with Standard & Poor's (S&P's) and Moody's Investors Service (Moody's).
On 17 April 2025, S&P revised the Group's corporate credit rating and the rating of the 2026 Notes to CCC+ with negative outlook from B-.
On 13 May 2025, Moody's revised the Group's corporate credit rating and the rating of the 2026 Notes to Caa2 with negative outlook from Caa1.
Underlying Operating Cash Flow and Free Cash Flow
Underlying operating cash flow amounted to $34 million (1H 2024: $169 million). This decrease was primarily driven by a $263 million decline in cash revenue due to lower sales volumes and reduced oil prices, and higher cash operating costs and working capital of $78 million. This was offset by $201 million lower cash taxes in the current period.
Free cash flow has decreased to $(188) million (1H 2024: $(126) million) primarily due to the decrease in underlying operating cash flow of $136 million as explained above. There was also contribution to decommissioning escrow fund of $12 million in the current period. The decrease was partially offset by a reduction in net cash used in investing activities of $62 million and reduced lease payments related to capital activities of $22 million.
Ghana tax assessments
Tullow has two ongoing disputed tax assessments that relate to the disallowance of loan interest deductions for the fiscal years 2010 - 2020 and proceeds received by Tullow Oil plc under Tullow's corporate Business Interruption Insurance policy. Both were referred to international arbitration in 2023, with first hearings scheduled for 2025. The parties have agreed a procedural timetable for the loan interest arbitration under which the first Tribunal hearing was due to have been held in the week commencing 30th June 2025. This was postponed to allow more time to continue settlement negotiations. The hearing on the Business Interruption Insurance proceeds remains scheduled for November 2025. Tullow continues to engage with the Government of Ghana, including the GRA, with the aim of resolving the assessments on a mutually acceptable basis.
Liquidity Risk Management and Going concern
The Directors consider the going concern assessment period to be up to 30 September 2026. The Group closely monitors and manages its liquidity headroom. Cash forecasts are regularly produced, and sensitivities run for different scenarios covering key judgements and assumptions including, but not limited to, changes in commodity prices, different production rates from the Group's producing assets and different outcomes on ongoing disputes or litigations and the timing of any associated cash outflows.
Management has applied the following oil price assumptions for the going concern assessment based on forward prices and market forecasts:
Base Case: $66/bbl for 2025; $65/bbl for 2026.
Low Case: $60/bbl for 2025; $60/bbl for 2026.
To consider the principal risks to the cash flow projections, a sensitivity analysis has been performed which is represented in the Low Case which management considers to be severe, but plausible, given the cumulative impact of the sensitivities applied. The most significant risk would be a sustained decline in oil prices. The analysis has been tested by including a 10% production decrease and a 5% increase in operating costs compared to the Base Case. Management has also considered additional outflows in respect of all ongoing disputes and litigations within the Low Case, with an additional $68 million outflow included for the cases expected to progress in the going concern period. Based on the legal opinions received by management, the remaining disputes and litigations are not expected to conclude within the going concern period or have remote outcomes, therefore no outflows have been included in that respect in the Low Case. In the event of negative outcomes after the going concern period, management would use all available court processes to appeal such rulings which, based on observable court timelines, would likely take in excess of a further year.
The Group is reliant on the continued provision of external financing. The c.$1.3 billion 2026 Notes fall due within the going concern period in May 2026 and will require refinancing to ensure the Group has sufficient liquidity to meet its financial obligations. The Directors intend to complete a holistic refinancing of the existing debt capital structure, consisting of c.$1.3 billion 2026 Notes and a $400m Secured Notes Facility, in advance of this date. The $150 million RCF facility was repaid and cancelled in full on 29 July 2025.
A fundamental assumption in concluding that the Group is a going concern is a successful execution of a holistic refinancing in advance of the 2026 Notes falling due for payment. Management is evaluating a range of refinancing options and is in ongoing discussions with banks, commodity traders and other private sources of funding to secure financial commitments towards the refinancing, supported by the underlying value of the Group's assets and cash generation from the Group's producing fields to support future debt service and repayment. Completion of the Gabon sale transaction and associated receipt of $307 million proceeds on 29 July 2025 has materially reduced the Group's net debt and reduced the risk associated with the holistic debt refinancing. The successful execution of a holistic refinancing is subject to agreement of terms with a range of stakeholders including bondholders and favourable macroeconomic and market conditions including but not limited to oil price, credit ratings and accessibility of High Yield Bond markets and is therefore outside the control of management.
In addition, a sale and purchase agreement for the sale of Tullow Kenya BV, which holds Tullow's entire working interests in Kenya, for a total consideration of at least $120 million has been entered into with Auron Energy E&P Limited, an affiliate of Gulf Energy Limited. Completion of the transaction, which is subject to regulatory approvals, and receipt of a $40 million completion payment are assumed in Q3 2025, with a further $40 million payment due on approval of a field development plan assumed in Q4 2025 in the Base Case; in the Low Case, receipt of the second $40 million instalment payment is assumed in June 2026. Completion of this transaction and associated payments due on completion and field development plan approval will further reduce the Group's net debt and are therefore expected to reduce the risk associated with the holistic debt refinancing.
Implications and material uncertainty
The Base Case and the Low Case scenarios forecast a liquidity shortfall in May 2026 when the c.$1.3 billion 2026 Notes become due for payment, unless the Directors execute a holistic refinancing of the Group's debt capital structure in advance of that date. The completion of the sale of Tullow Oil Gabon SA has removed the material uncertainty in relation to obtaining sufficient liquidity to cover the expiration of the RCF at the end of June 2025 which had been identified at year-end 2024.
The Directors have initiated a process to execute a holistic refinancing following discussions with banks, commodity traders and other private sources of funding. The Directors believe this is achievable before May 2026, noting the risks associated with wider market conditions and agreement on terms with a range of stakeholders including bondholders.
The Directors note that despite expressions of interest from private as well as public parties for participation in the holistic refinancing, executing a holistic refinancing is outside the control of the Group. If the Directors were unable to execute a holistic refinancing, the ability of the Group to continue trading would depend upon the Group being able to negotiate a financial restructuring proposal with its creditors and, if necessary, that proposal being approved by shareholders. Whilst the Board would seek to negotiate such a financial restructuring proposal with its creditors, it is possible that the creditors would not engage with the Board in those circumstances. There would therefore be a possible risk of the Group entering into insolvency proceedings, which the Directors consider would likely result in limited or no value being returned to shareholders.
The Directors have concluded that executing a holistic refinancing of the Group's debt capital structure by May 2026 at the latest is outside the control of the Group. This is therefore a material uncertainty that may cast significant doubt over the Group's ability to continue as a going concern. Notwithstanding this material uncertainty, the Board has confidence in the Group's ability to execute a holistic refinancing by May 2026. This is based on the plans in place to execute a holistic refinancing and ongoing discussions with banks, traders, and other private sources of funding which are supported by the underlying value of the Group's assets and cash generation from the Group's producing fields to support future debt service and repayment. On this basis, the Board have prepared the Financial Statements on a going concern basis. The Financial Statements do not include the adjustments that would result if the Group was unable to continue as a going concern.
2025 principal risks and uncertainties
The Company risk profile has been closely monitored throughout the year, with consideration given to the risks to delivering the Business Plan, as well as whether external factors such as geo-political factors, global pandemics and oil price volatility have resulted in any new risks or changes to existing risks. The impact of these factors has been considered and managed across all principal risks. The Directors have reviewed the principal risks and uncertainties facing the Company and concluded that for the remaining six months of the financial year are substantially unchanged from those disclosed in the 2024 Annual Report and are listed below.
1. Business plan not delivered
2. Asset integrity breach

Events since 30 June 2025
On 21 July 2025, Tullow announced that it had signed a sale and purchase agreement with Auron Energy E&P Limited, an affiliate of Gulf Energy Limited, for the sale and purchase of 100% of the shares in Tullow Kenya BV (refer to note 10 for the details of the transaction).
On 29 July 2025, following satisfaction of all conditions precedent under the sale and purchase agreement, Tullow completed the sale of its 100% interest in Tullow Oil Gabon SA, which holds all of Tullow's non-operated working interests in Gabon (discussed in note 10 Held for sale and discontinued operations), to the Gabon Oil Company for a total cash consideration of $307 million, net of tax and customary adjustments. This is a non-adjusting event as at 30 June 2025 under IAS 10 Events after the Reporting Period. The financial impact of the disposal cannot be disclosed in the 2025 half-year results as completion accounting is still underway, and the relevant disclosures will be made in the Group's 2025 annual financial statements. The transaction is subject to a capital gains tax of $52 million as agreed with the Gabon Tax Authority, which will be paid by Gabon Oil Company. On completion, this will be recorded as an income tax expense with a corresponding pre-tax gain on disposal and no deferred tax recognised.
On 29 July 2025, the RCF of $150 million was repaid and cancelled in full.
There have not been any other events since 30 June 2025 that have resulted in a material impact on the half-year results.
