Material accounting policies, judgements and estimation uncertainty Basis of measurement The consolidated financial statements have been prepared on a going concern basis using the historical cost convention, except for the revaluation of certain financial assets and financial liabilities, under International Financial Reporting Standards (IFRS), to fair value, including derivative instruments. Historical cost is generally based on the fair value consideration given in exchange for the assets and liabilities. Going concern Management closely monitor the funding position of the Group, including monitoring compliance with covenants and available facilities to ensure sufficient headroom is maintained to fund operations. Management have considered a number of risks applicable to the Group that impact on the Group\u2019s ability, and the Parent Company's ability, to continue as a going concern. Short-term and long-term cash forecasts are prepared on a weekly and quarterly basis respectively, along with any related sensitivity analysis. This allows proactive management of any business risk including liquidity risk. The Directors consider the preparation of the financial statements on a going concern basis to be appropriate. This is due to the following key factors: \u2022 A well-hedged portfolio over the next 12 months; \u2022 Reserves Based Lending (RBL) is undrawn providing liquidity headroom of $1,300 million, plus $214 million of cash at the end of February 2026; and \u2022 Robust operational performance and a well-diversified portfolio.

The oil and gas price assumptions used in the going concern and viability assessments represent management's current best estimates of future commodity prices at the date of approval of the Annual Report and Accounts, as supported by data from third-party analysis, whereas the commodity prices used in impairment testing (see note 19) are based on market conditions at 31 December 2025. Owing to the ongoing fluctuations in commodity demand and price volatility, management prepared sensitivity analyses to the forecasts and applied a number of plausible downside scenarios, including decreases in production of 10%, reduced sales prices of 20% and increases in operating and capital expenditures of 10%. Management aggregated these scenarios to create a reasonable combined worst-case scenario. The sensitivity analysis showed that, without any consideration of the mitigation strategies within management\u2019s control, there was no reasonably possible scenario that would result in the business being unable to meet its liabilities as they fell due. In addition, reverse stress tests have been performed reflecting further reductions in commodity prices, prior to any mitigating actions, to determine at what levels prices would have to reach such that there is no liquidity headroom left. The stress tests demonstrated that the likelihood of the fall in prices required to cause a liquidity issue is considered sufficiently remote in the context of the mitigation strategies available to management. The mitigation strategies within the control of management include a reduction in uncommitted capital expenditure and variable opex savings in the low production scenario. The analysis demonstrated that the Group would still continue to comply with financial covenants and have sufficient liquidity throughout the period to 30 June 2027 to continue trading. Notwithstanding the Group having net current liabilities at 31 December 2025 of $303.9 million (31 December 2024: $456.5 million), there are sufficient undrawn facilities available to enable current liabilities to be settled as they fall due. Based on their assessment of the Group\u2019s financial position in the period to 30 June 2027, the Directors believe that the Group will be able to continue in operational existence for the foreseeable future. Accordingly, they continue to adopt the going concern basis of accounting in preparing the financial statements. Basis of consolidation The consolidated financial statements of the Group includes the financial information of Ithaca Energy plc and all wholly- owned subsidiaries as set out in note 32. All intergroup transactions and balances have been eliminated on consolidation. Subsidiaries are all entities over which the Group has control. The plc controls an entity when the Group is exposed to or has rights to variable returns from its investments with the entity and has the ability to affect those returns through its power over the investee. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated on the date that control ceases. Impact of climate change on the financial statements and related notes Judgements in respect of exploration and evaluation assets and estimates made for all other areas in assessing the impact of climate change and the energy transition Climate change and the transition to a lower-carbon system were considered in preparing the consolidated financial statements. These may have the potential for significant impacts on the carrying values of the Group\u2019s assets and liabilities discussed below as well as on assets and liabilities that may be reflected in the future. There is also the potential for significant impact on future cash flows. There is generally a high level of uncertainty about the speed and magnitude of impacts of climate change which, together with limited historical data, provides significant challenges in the preparation of forecasts and financial plans with a wide range of potential future outcomes. The Group\u2019s ambition is to have one of the lowest carbon emission portfolios in the UK North Sea and to achieve Net Zero (whereby the amount of CO 2 added by the Group\u2019s activities is no greater than the amount taken away), on a net equity basis (by applying the Group\u2019s working interest in each respective asset to the total emissions of that asset), and in respect of Scope 1 and 2 emissions, by 2040, ten years ahead of the North Sea Transition Deal commitment. This will be achieved by optimising the Group\u2019s current portfolio in the short term and fundamentally transitioning the Group\u2019s portfolio over the medium to long term whilst maintaining forecast levels of production. Initiatives include, but are not limited to, operational improvements, offshore electrification, acquisition and investment into lower carbon intensity assets and the eventual cessation of production of mature fields which have higher carbon intensity. In addition, the Eni UK business combination in 2024 and the Seagull and Cygnus acquisitions in 2025 have added relatively low emission assets, thereby reducing the carbon footprint of the Group. Where the Group cannot reduce Scope 1 and Scope 2 emissions, Ithaca Energy will invest in carbon offsets to achieve the Group\u2019s goal of Net Zero. All new economic investment decisions include estimated costs of the energy transition based on existing technology and estimated costs of carbon and these opportunities are assessed on their climate impact potential and alignment with Ithaca Energy\u2019s Net Zero target, taking into account both greenhouse gas volumes and emissions intensity. Specific considerations of the potential impacts of climate change on significant judgements and estimates used in the consolidated financial statements are considered below. The items outlined below are likely to manifest themselves over a number of years and are, therefore, not generally considered to represent 'key sources of estimation uncertainty' as required by IAS 1 (being those which could have a material impact on the Group\u2019s results in the 12 months following the date of the consolidated statement of financial position) which are separately disclosed later in this note. Impairment of goodwill and property, plant and equipment The energy transition has the potential to significantly impact future commodity and carbon prices in that as the UK and global energy system decarbonises, reduced demand for oil and gas products in favour of low carbon alternatives could cause oil and gas prices to fall which would, in turn, affect the recoverable amount of goodwill and property, plant and equipment. In the current period management\u2019s estimate of the long-term commodity price assumptions are, in nominal terms from 2032, $80/bbl for Brent Crude and 79p/therm for UK NBP gas. Further details of climate change, including a sensitivity in this area are provided in note 19. Recoverable values used for impairment testing for all cash-generating units (CGUs) include the estimated cost of UK carbon emissions allowances in real terms for CO 2 e of \u00a345/tonne, \u00a365/tonne and \u00a380/tonne for 2026, 2027 and 2028 respectively. The recoverable value of CGU\u2019s may be impacted by future carbon pricing legislation changes, which could increase operating costs through higher emissions allowances or the introduction of other carbon pricing mechanisms. Electrification of offshore operations for specific assets is planned in line with the Group\u2019s 2040 Net Zero ambitions and where feasible based on existing technology and economic value, estimated electrification costs of a market participant are included within the assessment of the recoverable value of the relevant CGU. Property, plant and equipment \u2013 depreciation and useful economic lives The energy transition has the potential to reduce the expected useful economic lives of assets and hence accelerate depreciation charges. Although no changes have been identified or recognised to date, as noted in the Strategic Report on page 58, it is anticipated that certain higher emission-intensity assets such as FPF-1 and Alba will cease production in the short to medium term and will be replaced by new lower-emission intensity assets. Management does not currently expect the useful economic lives of the Group\u2019s reported property, plant and equipment to significantly change solely as a result of the energy transition. However, significant capital expenditure is still required for ongoing projects and therefore, the useful lives of future capital expenditure may be different. Intangible assets \u2013 exploration and evaluation assets The impacts of climate change and the energy transition may affect the viability of exploration prospects, for example, due to the impact on future commodity and carbon prices (as explained above) or due to the increased risk of regulatory challenge as prospects progress through to development. The recoverability of the existing intangibles was considered during 2025, however, no significant write-offs were identified as a result of climate change considerations. Viability of these assets will continue to be assessed on a regular basis. Decommissioning provisions Most of the Group\u2019s existing decommissioning obligations are estimated to be completed over the course of the next 20 years. The impacts of climate change and the energy transition may bring forward the expected timing of decommissioning activity, increasing the present value of the associated decommissioning provisions. The potential impact of a reasonably possible acceleration of estimated decommissioning dates, which considers the potential impact of the energy transition, is considered to be two years. The impact of such an acceleration of cessation of production across the Group\u2019s producing assets with estimated cessation of production dates from 2028 onwards, would result in an increase in the decommissioning provision of approximately $109 million (2024: $93 million). The risk in this area may increase if key assets within the Group\u2019s existing exploration, appraisal and development portfolio proceed to the production stage, as this is likely to significantly extend the life of the Group\u2019s portfolio, in some cases to 2050 or beyond. While the pace of the transition to a lower-carbon economy is uncertain, oil and gas demand is expected to remain a key element of the energy mix for many years based on stated policies, commitments and announced pledges to reduce emissions. Therefore, given the estimated useful lives of the Group\u2019s oil and gas portfolio, a material adverse change is not anticipated to the carrying value of the Group\u2019s assets and liabilities in the short term as a result of climate change and the transition to a lower-carbon economy. Business combinations Business combinations are accounted for using the acquisition method. The cost of a business combination is measured as the fair value of the consideration given for the assets acquired, equity instruments issued and liabilities incurred or assumed at the date of completion of the business combination. Transaction costs incurred are expensed and included in administrative expenses. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the date of the business combination. The excess of the cost of the business combination over the fair value of the Group\u2019s share of the identifiable net assets acquired is recorded as goodwill. If the cost of the business combination is less than the Group\u2019s share of the net assets acquired, the difference is recognised directly in the consolidated statement of profit or loss as a gain on bargain purchase. Goodwill Capitalisation Goodwill is initially recognised and measured as set out above. Following initial recognition, goodwill is measured at cost less any accumulated impairment losses. In the event of a business combination or acquisition of an interest in a joint operation in which the activity constitutes a business, as defined in IFRS 3 Business Combinations, the acquisition method of accounting is applied. Goodwill represents the difference between the aggregate of the fair value of purchase consideration transferred at the acquisition date and the fair value of the identifiable assets, liabilities and contingent liabilities acquired, less any non-controlling interest. If, however, the fair value of the purchase consideration transferred is lower than the fair value of the identifiable assets and liabilities acquired, less non-controlling interest, the difference is recognised in the income statement as negative goodwill. The Group\u2019s goodwill is related to the requirement to recognise deferred tax for the difference between the assigned fair values and the related tax base (technical goodwill). The fair value of the Group\u2019s licences are based on post-tax cash flows or benchmarked multiples. In accordance with IAS 12 paragraphs 15 and 24, a provision is made for deferred tax corresponding to the difference between the acquisition cost and the transferred tax depreciation basis. The offsetting entry to this deferred tax is goodwill. Hence, goodwill arises as a technical effect of deferred tax. Impairments are expected to arise as the deferred tax liability naturally unwinds in the normal course of business. Goodwill is initially measured at cost. Following initial recognition, goodwill is measured at cost less any accumulated impairment. Goodwill acquired in a business combination is, from the acquisition date, allocated to each of the Group\u2019s operating segments. This is subsequently tested for impairment at the Group\u2019s operating segment level based on the aggregation of any headroom arising from asset impairment tests. Impairment Goodwill is tested annually for impairment and also when circumstances indicate that the carrying value may be at risk of being impaired. Impairment is determined for goodwill by assessing the recoverable amount of each CGU or Group of CGUs to which the goodwill relates. If the recoverable amount of a CGU is less than its carrying amount, the impairment loss is allocated first to reduce the carrying amount of goodwill allocated to the unit and then to the other assets of the unit pro-rata based on the carrying amount of each asset in the unit. Any impairment loss is recognised in the consolidated statement of profit or loss. Impairment losses relating to goodwill cannot be reversed in future periods. The CGU for the purposes of the goodwill test is the North Sea, i.e. the entire Group portfolio of oil and gas assets (including E&E assets) which is consistent with the operating segment view of the business. Investments Investments in listed oil and gas shares are initially recorded at cost and are subsequently remeasured on a fair value through other comprehensive income basis due to an irrevocable designation having been made in this respect. Interest in joint ventures Under IFRS 11, joint arrangements are those that convey joint control which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control. Investments in joint arrangements are classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor. The Group\u2019s interest in joint operations (e.g. exploration and production arrangements) are accounted for by recognising its assets (including its proportionate share of assets held jointly), its liabilities (including its proportionate share of liabilities incurred jointly), its revenue from the sale of its proportionate share of the output arising from the joint operation and its expenses (including its proportionate share of any expenses incurred jointly). Revenue The sale of crude oil, gas or condensate represents a single performance obligation, being the sale of barrels equivalent on collection of a cargo or on delivery of commodity into an infrastructure. Revenue is accordingly recognised for this performance obligation when control over the corresponding commodity is transferred to the customer. Revenue is recognised at a point in time and is measured based on the consideration to which the Group expects to be entitled in a contract with a customer and excludes amounts collected for third parties. Details of hedging gains and losses presented in revenue are discussed in the hedging accounting policy set out below. Tariff income is recognised as the underlying commodity is shipped through the pipeline network based on established tariff rates. Foreign currency translation Items included in these consolidated financial statements are measured using the currency of the primary economic environment in which the Group and its subsidiaries operate (the functional currency). The consolidated financial statements are presented in US Dollars, which is the Group\u2019s presentation currency as well as the functional currency of the Parent Company and each of its subsidiaries. In preparing the financial statements of the Parent and its subsidiaries, transactions in currencies other than the entity\u2019s functional currency (foreign currencies) are recognised at the rates of exchange prevailing on the dates of the transactions. At each reporting date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing at that date. Non-monetary items carried at fair value that are denominated in foreign currencies are translated at the rates prevailing at the date when the fair value was determined. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the statement of profit or loss. Exchange differences are recognised in profit or loss in the period in which they arise except for: \u2022 Exchange differences on foreign currency borrowings relating to assets under construction for future productive use, which are included in the cost of those assets when they are regarded as an adjustment to interest costs on those foreign currency borrowings; and \u2022 Exchange differences on transactions entered into to hedge certain foreign currency risks (see below under financial instruments/hedge accounting). Dividend distribution Dividend distribution to the Company\u2019s shareholders is recognised as a liability in the Company\u2019s financial statements in the period in which the dividends are approved by the Company\u2019s shareholders. Details of dividends paid and declared are set out in note 34. Financial instruments All financial instruments are initially recognised at fair value on the statement of financial position. Measurement in subsequent periods is dependent on the classification of the respective financial instrument. The Group derecognises a financial asset only when the contractual rights to the cash flows from the asset expire, or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another entity. The difference between the carrying amount of the financial asset derecognised and the consideration received/ receivable is recognised in profit or loss. The Group derecognises financial liabilities when, and only when, the Group\u2019s obligations are discharged, cancelled or have expired. The Group considers whether refinancing arrangements represent settlement of the existing debt and issuance of a new debt or an exchange or modification of the previous debt. In making this assessment, the Group considers, amongst other factors, pre-existing early redemption options in the original agreement, the group of lenders to which the new debt is offered and any preferential terms or rights given to the original lenders. Where the new debt is considered to represent an arms-length market offering, the issuance of the new debt is viewed as separate from the extinguishment of the old debt and is treated as the derecognition of the original liability and the recognition of a new liability. The difference between the carrying amount of the financial liability derecognised and the consideration paid/payable (excluding consideration payable for fees incurred on the new liability or accrued interest) is recognised in profit or loss. IFRS 9 classifications Cash and cash equivalents are classified at amortised cost which equates to its fair value. Accounts receivable and long-term receivables are classified and carried at amortised cost less expected credit losses. These items have a business model of held to collect and the terms of the financial instrument meet the classification of solely payments of interest on principle outstanding. Accounts payable, accrued liabilities, certain other long-term liabilities and borrowings are classified as other financial liabilities and carried at amortised cost using the effective interest method. Amortised cost is calculated by taking into account any issue costs, discount or premium. Contingent consideration is measured at fair value though profit or loss. Although the Group does not intend to trade its derivative financial instruments, they are required to be carried at fair value with the treatment of fair value movements explained further below. Transaction costs, presentation and cash flows Transaction costs that are directly attributable to the acquisition or issue of a financial asset or liability (excluding the costs directly attributable to the new loan commitment facilities) have been included in the carrying value of the related financial asset or liability and are amortised to consolidated net earnings over the life of the financial instrument using the effective interest method. Directly attributable fees paid on the establishment of new loan commitment facilities are capitalised to the extent that it is probable that some or all of the facility will be drawn down. These costs are recognised on a systematic basis over the period the Group is able to draw down. Fees that are calculated based on the usage of the facility (including letter of credit fees) are expensed as incurred. Borrowings are presented as non-current when they are not due to be settled within 12 months after the reporting period or where the Group has the right at the end of the reporting period to defer settlement for at least 12 months after the reporting period. Cash flows relating to refinancing are presented in the statement of cash flows on a net basis where that reflects the actual cash flows received by the Group. The refinancing proceeds in the statement of cash flows are stated after deduction of fees which were deducted from the amount paid to the Group. Other fees paid on refinancing are presented as a separate line item within financing activities or within Interest and charges paid in the statement of cash flows. Impairment of financial assets For trade receivables and accrued income, the Group applies a simplified approach in calculating expected credit losses (ECLs). Therefore, the Group does not track changes in credit risk, but instead recognises any material loss allowance based on lifetime ECLs at each reporting date. For all other financial assets, the Group measures the loss allowance using 12-month expected credit losses unless there was a significant increase in credit risk since initial recognition in which case the loss allowance is measured using lifetime expected credit losses. In making this assessment whether the credit risk increased significantly since initial recognition, the Group considers both quantitative and qualitative information that is reasonable and supportable, including historical experience and forward-looking information that is available without undue cost or effort. The Group considers that the credit risk increased significantly since initial recognition when the credit rating changes, the debtor has significant financial difficulty or if there was a breach of contract. For balances that are beyond 30 days overdue it is presumed to be an indicator of a significant increase in credit risk. The Group considers a financial asset in default when contractual payments are 90 days past due. However, in certain cases, the Group may also consider a financial asset to be in default when internal or external information indicates that the Group is unlikely to receive the outstanding contractual amounts in full before taking into account any credit enhancements held by the Group. A financial asset is written off when there is no reasonable expectation of recovering the contractual cash flows. Financial assets written off may still be subject to enforcement activities under the Group\u2019s recovery procedures, taking into account legal advice where appropriate. Any recoveries made are recognised in profit or loss. Derivative financial instruments The Group enters into a variety of derivative financial instruments to manage its exposure to commodity risks, interest rate and foreign exchange rate risks. These instruments include: commodity swaps, collars and options; foreign exchange forward contracts and collars; and interest rate swaps. Further details of derivative financial instruments are disclosed in notes 30 and 31. Derivatives are recognised initially at fair value at the date a derivative contract is entered into and are subsequently remeasured to their fair value at each reporting date. The resulting gain or loss on remeasurement of derivatives is recognised in profit or loss immediately unless the derivative is designated in a hedge relationship and effective as a hedging instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship. A derivative with a positive fair value is recognised as a financial asset whereas a derivative with a negative fair value is recognised as a financial liability. Derivatives are not offset in the financial statements unless the Group has both a legally enforceable right and intention to offset. A derivative is presented as a non-current asset or a non-current liability if the remaining maturity of the instrument is more than 12 months and it is not due to be realised or settled within 12 months. Other derivatives maturing in less than 12 months and expected to be realised or settled in less than 12 months are presented as current assets or current liabilities. Hedge accounting The Group designates certain derivatives as hedging instruments in respect of commodity risks in cash flow hedges. At the inception of the hedge relationship, the Group documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Group documents whether the hedging instrument is highly effective in offsetting changes in fair values or cash flows of the hedged item attributable to the hedged risk. If a hedging relationship ceases to meet the hedge effectiveness requirement relating to the hedge ratio, but the risk management objective for that designated hedging relationship remains the same, the Group adjusts the hedge ratio of the hedging relationship (i.e. rebalances the hedge) so that it meets the qualifying criteria again. The Group designates only the intrinsic value of option contracts as a hedging instrument, i.e. excluding the time value of the option. The changes in the fair value of the aligned time value of the option are recognised in other comprehensive income and accumulated in the cost of hedging reserve. If the hedged item is transaction-related, the time value is reclassified to profit or loss when the hedged item affects profit or loss. If the hedged item is time period-related, then the amount accumulated in the cost of hedging reserve is reclassified to profit or loss on a rational basis \u2013 the Group applies straight-line amortisation. Those reclassified amounts are recognised in profit or loss in the same line as the hedged item. If the Group expects that some or all of the loss accumulated in the cost of hedging reserve will not be recovered in the future, that amount is immediately reclassified to profit or loss. The effective portion of changes in the fair value of derivatives and other qualifying hedging instruments that are designated and qualify as cash flow hedges is recognised in other comprehensive income and accumulated under the heading of cash flow hedge reserve, limited to the cumulative change in fair value of the hedged item from inception of the hedge. The gain or loss relating to the ineffective portion is recognised immediately in profit or loss, and is included in the 'other gains and losses' line item. Amounts previously recognised in other comprehensive income and accumulated in equity are reclassified to profit or loss in the periods when the hedged item affects profit or loss, in the same revenue line as the recognised hedged item. However, when the hedged forecast transaction results in the recognition of a non-financial asset or a non-financial liability, the gains and losses previously recognised in other comprehensive income and accumulated in equity are removed from equity and included in the initial measurement of the cost of the non-financial asset or non-financial liability. This transfer does not affect other comprehensive income. Furthermore, if the Group expects that some or all of the loss accumulated in the cash flow hedge reserve will not be recovered in the future, that amount is immediately reclassified to profit or loss. The Group discontinues hedge accounting only when the hedging relationship (or a part thereof) ceases to meet the qualifying criteria (after rebalancing, if applicable). This includes instances when the hedging instrument expires or is sold, terminated or exercised. The discontinuation is accounted for prospectively. Any gain or loss recognised in other comprehensive income and accumulated in cash flow hedge reserve at that time remains in equity and is reclassified to profit or loss when the forecast transaction occurs. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in the cash flow hedge reserve is reclassified immediately to profit or loss. If a hedge of a transaction-related item is discontinued part way through the life of the hedge (e.g. due to early termination of the swap, hedging resets), but the hedged item is still expected to occur, the amounts deferred in equity would remain in equity until the earlier of: (i) the hedged transaction occurring; or (ii) expectation that the amount deferred in equity will not be recovered in the future periods. Notes 30 and 31 set out details of the fair values of the derivative instruments used for hedging purposes, and movements in the cash flow hedge reserve and cost of hedging reserve in equity are detailed in note 30. Contingent and deferred consideration Contingent consideration in relation to a business combination or asset acquisition is accounted for as a financial liability and measured at fair value at the date of acquisition with any subsequent remeasurements recognised in profit or loss in accordance with IFRS 9. These fair values are generally based on risk-adjusted future cash flows discounted using appropriate discount rates. Changes in fair value of the contingent consideration that qualify as measurement period adjustments are adjusted retrospectively, with corresponding adjustments against goodwill. Measurement period adjustments are adjustments that arise from additional information obtained during the 'measurement period' (which cannot exceed one year from the date of the business combination) about facts and circumstances that existed at the date of the business combination. The subsequent accounting for changes in the fair value of the contingent consideration that do not qualify as measurement period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified as equity is not remeasured at subsequent reporting dates and its subsequent settlement is accounted for within equity. Other contingent consideration is remeasured to fair value at subsequent reporting dates with changes in fair value recognised in profit or loss. Deferred consideration is measured at amortised cost because the amount payable in the future is fixed. Settlement of contingent consideration is recorded as investing outflows in the cash flow statement to the extent that cumulative amounts paid do not exceed the amount recognised at the date of acquisition, with any excess recorded as an operating cash outflow. Settlement of deferred consideration is recorded as either an investing or financing outflow in the cash flow statement, depending on the substance of the arrangement at inception. Key considerations in forming this judgement will include the extent of inferred financing costs included in the overall consideration arrangements at acquisition, the period of time over which the payments are made, the rationale for agreeing to defer elements of the consideration and the general level of funding resources available to the Group at the time of acquisition. Cash and cash equivalents For the purpose of the statement of cash flows, cash and cash equivalents include investments with an original maturity of three months or less. In the statement of financial position, cash and bank balances comprise cash (i.e. cash on hand and demand deposits) and cash equivalents. Cash equivalents are short-term (generally with original maturity of three months or less), highly-liquid investments that are readily convertible to a known amount of cash and which are subject to an insignificant risk of changes in value. Cash equivalents are held for the purpose of meeting short-term cash commitments rather than for investment or other purposes. Inventories \u2013 hydrocarbon and materials Inventories of materials are stated at the lower of cost and net realisable value. Cost comprises direct materials and, where applicable, direct labour costs and those overheads that have been incurred in bringing the inventories to their present location and condition. Cost is determined on the first-in, first-out method. Current hydrocarbon inventories are stated at net realisable value, which is based on estimated selling price less any further costs expected to be incurred to completion and disposal/sale. Non-current oil and gas inventories are stated at historic cost. Provision is made for obsolete, slow-moving and defective items where appropriate. Lifting or offtake arrangements Lifting or offtake arrangements for oil and gas produced in certain of the Group\u2019s oil and gas properties are such that each participant may not receive and sell its precise share of the overall production in each period. The resulting imbalance between cumulative entitlement and cumulative volume sold is an \u2018underlift\u2019 included within inventories, or an \u2018overlift\u2019 included within trade and other payables in the statement of financial position. Both are stated at net realisable value using an observable year-end oil or gas market price. Movements during an accounting period are adjusted through cost of sales in the consolidated statement of profit or loss. Exploration and evaluation assets Oil and gas expenditure \u2013 exploration and evaluation (E&E) assets Geological and geophysical costs and costs incurred pre-licence are expensed as incurred. Costs directly associated with an exploration well are initially capitalised as an intangible asset until the drilling of the well is complete and the results have been evaluated. These costs include employee remuneration, materials and fuel used, freight costs and payments made to contractors. If potentially commercial quantities of hydrocarbons are not found, the exploration well costs are written off. If hydrocarbons are found and, subject to further appraisal activity, are likely to be capable of commercial development, the costs continue to be carried as an asset. If it is determined that development will not occur, that is, the efforts are not successful, then the costs are expensed. Costs directly associated with appraisal activity undertaken to determine the size, characteristics and commercial potential of a reservoir following the initial discovery of hydrocarbons, including the costs of appraisal wells where hydrocarbons were not found, are initially capitalised as an intangible asset. Upon external approval for development and recognition of proved or sanctioned probable reserves, the relevant expenditure is first assessed for impairment and, if required, an impairment loss is recognised. The remaining balance is then transferred to development and production (D&P) assets. If development is not approved and no further activity is expected to occur, then the costs are expensed. The determination of whether potentially economic oil and natural gas reserves have been discovered by an exploration well is usually made within one year of well completion, but can take longer, depending on the complexity of the geological structure. Exploration wells that discover potentially economic quantities of oil and natural gas in areas where major capital expenditure (e.g. an offshore platform or a pipeline) would be required before production could begin and where the economic viability of that major capital expenditure depends on the successful completion of further exploitation or appraisal work in the area remain capitalised on the balance sheet as long as such work is under way or firmly planned. Property, plant and equipment Oil and gas expenditure \u2013 D&P assets Capitalisation Costs of bringing a field into production, including the cost of facilities, wells and subsea equipment, direct costs including staff costs together with E&E assets reclassified in accordance with the above policy, are capitalised as a D&P asset. Normally each individual field development will form an individual D&P asset but there may be cases, such as phased developments, or multiple fields around a single production facility when fields are grouped together to form a single D&P asset. Depreciation All costs relating to a development are accumulated and not depreciated until the commencement of production. Depreciation is calculated on a unit of production basis based on the proved and probable reserves of the asset generally on a field-by-field basis. Any re-assessment of reserves affects the depreciation rate prospectively. Significant items of plant and equipment will normally be fully depreciated over the life of the field. However, these items are assessed to consider if their useful lives differ from the expected life of the D&P asset. Non-oil and natural gas operations Non-oil and gas assets are initially recorded at cost and depreciated over their estimated useful lives on a straight-line basis as follows: buildings 10 years, computers and office equipment 3 years and furniture and fittings 5 years. Impairment For impairment review purposes the Group\u2019s oil and gas assets are aggregated into CGUs typically on a field-by-field basis for development and production assets in accordance with IAS 36, and on a North Sea segment basis for exploration and evaluation assets in accordance with IFRS 6. A review is carried out at each reporting date for any indicators that the carrying value of the Group\u2019s assets may be impaired. Such reviews are carried out on a field-by-field basis for both development and production assets and exploration and evaluation assets. For assets where there are such indicators, an impairment test is carried out on the CGU. The impairment test involves comparing the carrying value with the recoverable value of an asset. The recoverable amount of an asset is determined as the higher of its fair value less costs to sell and value in use. If the recoverable amount of an asset is estimated to be less than its carrying amount, the carrying amount of the asset is reduced to the recoverable amount. The resulting impairment losses are written off to the consolidated statement of profit or loss. Previously impaired assets (excluding goodwill) are reviewed for possible reversal of previous impairment at each reporting date. The maximum possible reversal is capped at the net book value had the asset not been impaired in the past. Where an exploration and evaluation licence is relinquished, amounts capitalised in respect of the licence are written off to profit or loss in the period in which the licence is relinquished. Borrowing costs Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those assets until such time as the assets are substantially ready for their intended use or sale. All other borrowing costs are expensed as incurred. Borrowing costs directly attributable to E&E assets are not capitalised and are expensed directly to profit or loss when incurred. Decommissioning liabilities The Group records the present value of legal obligations associated with the retirement of long-term tangible assets, such as producing well sites and processing plants, in the period in which they are incurred with a corresponding increase in the carrying amount of the related long-term asset. Liabilities for decommissioning are recognised when the Group has an obligation to plug and abandon a well, dismantle and remove a facility or an item of plant and restore the site on which it is located, and when a reliable estimate can be made. Where the obligation exists for a new facility or well, such as oil and gas production or transportation facilities, the obligation generally arises when the asset is installed or the ground/environment is disturbed at the field location. In subsequent periods, the asset is adjusted for any changes in the estimated amount or timing of the settlement of the obligations. The amount recognised is the present value of the estimated future expenditure determined in accordance with local conditions and requirements. Changes in decommissioning cost estimates for assets that have either been fully written off or have ceased production are expensed as impairment charges in the period the change occurs. The carrying amounts of the associated decommissioning assets are depleted using the unit of production method in accordance with the depreciation policy for development and production assets. Actual costs to retire tangible assets are deducted from the liability as incurred. The unwinding of discount in the net present value of the total expected cost is treated as an interest expense. Changes in the estimates are reflected prospectively over the remaining life of the field. Where some or all of the expenditure required to settle a provision is expected to be reimbursed by another party, a reimbursement asset is recognised when, and only when, it is virtually certain that reimbursement will be received if the entity settles the obligation. The amount recognised for the reimbursement may not exceed the amount of the provision. Taxation Current tax Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amounts are those that are enacted or substantively enacted by the reporting date. Taxable profit differs from net profit, as reported in the consolidated statement of profit or loss, because it excludes items of income or expense that are taxable or deductible in other accounting periods and it further excludes items of income or expenses that are never taxable or deductible. Deferred tax Deferred tax is recognised using the liability method, providing for temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred tax is measured at the tax rates that are expected to be applied to the temporary differences when they are forecast to reverse, based on the laws that have been enacted or substantively enacted at each balance sheet date. Details of changes in EPL and other tax matters are set out in note 28. Deferred tax liabilities are not recognised if they arise from the initial recognition of goodwill and deferred tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred tax assets are recognised only to the extent that it is probable that future taxable profits will be available against which the temporary differences can be utilised. The carrying amount of deferred tax assets is reviewed at each balance sheet date and all available evidence is considered in evaluating the recoverability of these deferred tax assets. Deferred tax assets and liabilities are offset where there is a legally enforceable right to offset current tax assets and liabilities relating to taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balances on a net basis. Deferred Petroleum Revenue Tax (PRT) assets are recognised where PRT relief on future decommissioning costs is probable. Leases The Group assesses at contract inception all arrangements to determine whether it is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Group is not a lessor in any transactions, it is only a lessee. The Group recognises a right-of-use asset and a corresponding lease liability with respect to all lease arrangements in which it is the lessee. The Group has elected to apply Paragraph 6 of IFRS 16 to short-term leases (defined as leases with a lease term of 12 months or less) and leases of low-value assets (such as tablets and personal computers, small items of office furniture and telephones). Lease payments associated with these leases are expensed over the relevant lease term. Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognised, initial direct costs incurred and lease payments made at or before the commencement date less any lease incentives received. The right-of-use asset is depreciated over the useful life of the asset. The Group\u2019s right-of-use assets are included in property, plant and equipment (note 15). At the commencement date of the lease, the Group recognises lease liabilities measured at the present value of lease payments to be made over the lease term. In calculating the present value of lease payments, the Group uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is generally not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the lease payments (e.g. changes to future payments resulting from a change in an index or rate used to determine such lease payments) or a change in the assessment of an option to purchase the underlying asset. The Group has elected to apply the practical expedient under IFRS 16.15 to account for lease and associated non-lease components as a single lease component on a class-of-asset basis. Maintenance expenditure Expenditure on major maintenance refits or repairs is capitalised where it enhances the life or performance of an asset above its originally assessed standard of performance, replaces an asset or part of an asset which was separately depreciated and which is then written off, or restores the economic benefits of an asset which has been fully depreciated. All other maintenance expenditure is charged to the statement of profit or loss as incurred. Share-based payments The Group issues equity-settled share-based payments to certain employees. Equity-settled share-based payments are measured at fair value at the date of grant. The fair value is expensed over the vesting term either on a straight-line basis or as specified in the vesting terms, based on the Group\u2019s estimate of shares that will eventually vest and is adjusted for the effects of non-market-based vesting conditions. Fair value is measured by using a Black-Scholes or other appropriate valuation model. The expected life used in the model is adjusted based on management\u2019s best estimate for the effects of non-transferability, exercise restrictions and behavioural considerations. Retirement benefit costs The Group operates a defined contribution pension scheme and payments into this plan are charged as an expense as they fall due. There is no further obligation to pay contributions into the plan once the contributions specified in the plan rules have been paid. Short-term employee benefits A charge or liability is recognised for benefits accruing to employees in respect of salaries, bonuses, annual leave and sick leave in the period the related service is rendered at the undiscounted amount of the benefits expected to be paid for that service. Charges or liabilities recognised in respect of short-term employee benefits are measured at the undiscounted amount of the benefits expected to be paid in exchange for the related service. Segmental reporting The Group operates a single class of business being oil and gas exploration, development and production and related activities in a single geographical area, presently being the North Sea. The Group\u2019s segmental reporting structure remained in place for all periods presented and is consistent with the way in which the Group\u2019s activities are reported to the Board and Chief Decision Making Officer. The Group\u2019s activities are considered to be an individual operating segment due to the nature of the Group\u2019s operations being consistent, and such operations existing in a single geographical region that is covered by the same regulations. Changes in accounting pronouncements The Group has adopted all new and amended IFRS Standards effective in the consolidated financial statements for the period 1 January 2024 to 31 December 2025. There was no material impact from these or from any of the amendments to existing standards and interpretations which were effective from 1 January 2025. The Group has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective. New and revised IFRS Standards in issue but not yet effective As at 31 December 2025, the Group had not applied the following new Standards or revisions to existing IFRS Standards, that have been issued but were not yet effective at that date. Amendments to the SASB standards Amendments to the SASB standards to enhance their international applicability Revised IFRS Practice Statement 1 Management Commentary Revised IFRS Practice Statement 1 Management Commentary Amendments to IFRS 9 and IFRS 7 Amendments to the classification and measurement of financial instruments Amendments to IFRS 9 and IFRS 7 Contracts referencing nature-dependent electricity Annual improvements to IFRS Annual improvements to IFRS Accounting Standards \u2013 volume 11 IFRS 18 Presentation and disclosures in financial statements IFRS 19 Subsidiaries without public accountability: disclosures Amendments to IFRS 19 Amendments to IFRS 19 Subsidiaries without public accountability: disclosures Translation to a Hyperinflationary Amendments to IAS 21 Presentation Currency With the exception of IFRS 18, the Group does not expect that the adoption of the new Standards or amendments to existing Standards, listed above, will have a material impact on the consolidated financial statements of the Group in future periods. IFRS 18 \u2018Presentation and Disclosure in Financial Statements\u2019 will supersede IAS 1 \u2018Presentation of Financial Statements\u2019 and is effective for annual periods beginning on or after 1 January 2027 subject to endorsement by the UK Endorsement Board. IFRS 18 (and consequential amendments made to IAS 7 \u2018Statement of Cash Flows\u2019, IAS 8 \u2018Accounting Policies: Changes in Accounting Estimates and Errors\u2019, IAS 33 \u2018Earnings per share\u2019 and IFRS 7 \u2018Financial Instruments: Disclosures\u2019) introduces several new requirements that are expected to impact the presentation and disclosure of the Group\u2019s consolidated financial statements. These new requirements include: \u2022 Requirements to classify all income and expenses included in the statement of profit or loss into one of five categories and to present two new mandatory subtotals. \u2022 Requirement to use the operating profit subtotal as the starting point for the indirect method of reporting cash flows from operating activities in the statement of cash flows. \u2022 Specific classification requirements for interest paid/received and dividends received in the statement of cash flows such that interest and dividend receipts are included as investing cash flows and interest paid as financing cash flows. \u2022 Required disclosures about certain non-GAAP measures (\u2018management defined performance measures\u2019) in a single note to the financial statements. \u2022 Enhanced guidance on the aggregation of information across all the primary financial statements and the notes. The Group\u2019s evaluation of the effect of adopting IFRS 18 is ongoing but it is not currently anticipated that IFRS 18 will have any material quantitative impact but will have a significant impact on the presentation of the Group\u2019s financial statements and related disclosures. Non-GAAP measures In measuring the Group\u2019s adjusted operating performance, additional financial measures derived from the reported results have been used by management in order to eliminate factors which distort year-on-year comparisons. The Group\u2019s adjusted performance is used to explain year-on-year changes when the effect of certain items is significant, including impairment charges on oil and gas assets, restructuring costs, business combination costs, one-off finance charges related to refinancing, the tax effect of these items where applicable and non-cash deferred tax charges on changes to EPL. Adjusted EBITDAX, adjusted net income, adjusted EPS, unit operating expenditure, leverage ratio, adjusted net debt and certain other reported metrics are non-GAAP measures that are not specifically defined under IFRS or other generally accepted accounting principles. Further details are set out on pages 220 to 221. Critical judgements and key sources of estimation uncertainties Key sources of estimation uncertainty The key assumptions concerning the future, and other key sources of estimation uncertainty at the reporting period that may have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are discussed below. Estimates in oil and gas reserves and contingent resources The Group\u2019s estimates of oil and gas reserves and contingent resources, and the associated production forecasts, are used in the impairment testing of property, plant and equipment and goodwill, in the measurement of depletion and decommissioning provisions, the measurement of certain elements of contingent consideration, the going concern assessment, the viability assessment and in the determination of whether deferred tax assets are recoverable. The business of the Group is to enhance hydrocarbon recovery and extend the useful lives of mature and underdeveloped assets and associated infrastructure in a profitable and responsible manner. Estimates of oil and gas reserves and contingent resources require significant judgement. Factors such as the availability of geological and engineering data, reservoir performance data, drilling of new wells and estimates of future oil and gas prices all impact on the determination of the Group\u2019s estimates of its oil and gas reserves, which could result in different future production profiles affecting prospectively the discounted cash flows used in impairment testing. The Group\u2019s estimates of reserves and resource volumes used for accounting purposes are built up from historically-matched models for operated assets and principally from operators\u2019 estimates for non-operated assets. A review process is undertaken to compare the results of the Group\u2019s internal estimates to those of an independent consultant to understand any differences in underlying assumptions to ensure there are no significant unreconciled differences between the estimates. For the purposes of depletion and decommissioning estimates, the Group uses proved and probable reserves; and for the purposes of the impairment tests performed and deferred tax asset recoverability, the Group considers the same proved and probable reserves as well as risked resource volumes. These risking adjustments are reflective of management\u2019s assessment of technical and commercial factors that reflect the value considerations of a market participant. Changes in estimates of oil and gas reserves and resources resulting in different future production profiles will affect the discounted cash flows used in impairment testing, the anticipated date of decommissioning, the depletion charges in accordance with the unit of production method and the recoverability of deferred tax assets. The sensitivity of the Group\u2019s impairment tests and deferred tax recoverability assessments to key sources of estimation uncertainty, including reserves and resources, is discussed below. Estimates in impairment of oil and gas assets and goodwill Determination of whether the Group\u2019s oil and gas assets (note 15) or goodwill (note 18) have suffered any impairment requires an estimation of the recoverable amount of the CGU to which oil and gas assets and goodwill have been allocated. Projected future cash flows are used to determine a fair value less cost to sell to establish the recoverable amount. Key assumptions and estimates in the impairment models relate to: commodity prices that are based on an external view of forward curve prices that are considered to be a best estimate of what a market participant would use; discount rates which reflect management\u2019s estimate of a market participant post-tax weighted average cost of capital; and oil and gas reserves and resources on a risked basis as described above. Management\u2019s estimates of a market participant\u2019s view of pricing and discount rates are supplied by an independent consultant. The sensitivity of the Group\u2019s carrying amounts to these assumptions is illustrated by the impairments and reversals disclosed in note 19, and by the sensitivity disclosures in note 19. Sensitivity disclosures include, in particular, the impact of a 20% reduction in forecast revenues. Contingent consideration Liabilities for contingent consideration have been recognised on certain business combinations, which are measured at fair value at acquisition and remeasured at fair value through profit and loss at each reporting date. The amounts of contingent consideration ultimately payable depend on several factors, including the progress of certain of the oil and gas properties acquired and the achievement of certain production and commodity price thresholds. Management has estimated the fair value as the aggregate value of each element of the contingent consideration in each case using an appropriate valuation technique, taking into account the likelihood of occurrence of each contingent event and the net present value of the amount potentially payable. Where applicable, risking assumptions applied in the measurement of contingent consideration were consistent with those applied in the fair valuation of the related oil and gas properties. A 20% decrease in the probability of a trigger event occurring and hence a payment being due, with all other assumptions held constant, would result in a decrease in contingent consideration of $81.8 million (2024: $84.2 million). Whereas a 20% increase in probability of a trigger event occurring, with all other assumptions held constant, would result in an increase in contingent consideration of $64.1 million (2024: $77.1 million). Decommissioning provision estimates Amounts used in recording a provision for decommissioning are estimates based on current legal and constructive requirements and current technology and price levels for the removal of facilities and plugging and abandoning of wells. Due to changes in relation to these items, the future actual cash outflows in relation to decommissioning are likely to differ in practice. To reflect the effects due to changes in legislation, requirements, technology and price levels, the carrying amounts of decommissioning provisions are reviewed on a regular basis. The effects of changes in estimates do not give rise to prior year adjustments and are dealt with prospectively. For operated assets, cost estimates are based on management\u2019s assessment of work programmes (including durations) and supply chain conditions including, amongst other factors, applicable vessel and rig rates and durations. For non-operated assets, cost estimates are arrived at by management\u2019s review of the basis of estimates as provided by the respective operators. While the Group uses its best estimates and judgement, actual results could differ from these estimates. Expected timing of expenditure can also change, for example, in response to changes in laws and regulations or their interpretation, and/ or due to changes in commodity prices. The payment dates are uncertain and depend on the production lives of the respective fields. Management does not expect any reasonable change in the expected timing of decommissioning to have a material effect on the decommissioning provisions, assuming cash flows remain unchanged. Decommissioning costs are expected to be incurred over the next 40 years. The Group uses a nominal discount rate of 3.74% for the first five years and 4.75% thereafter (31 December 2024: 4.38% for the first five years and 4.86% thereafter), based on the average risk-free rate over the second half of 2025, to discount the estimated costs. The inflation rate applied to estimated costs is 2.0% (2024: 2.0%). A reduction or an increase in this discount rate of 1% would increase or reduce the decommissioning liabilities by approximately $300 million or $260 million, respectively (2024: $288 million or $247 million, respectively), and is not expected to have a material impact on the corresponding decommissioning reimbursement asset. For further details regarding the estimated value, inputs and assumptions refer to note 23. Given the large number of variables involved, management consider that it is not practical to provide sensitivities for the various other individual assumptions but the aggregated impact of related changes in the next 12 months could be material. Taxation estimates The Group\u2019s operations are subject to a number of specific tax rules which apply to exploration, development and production companies such as the Energy Profits Levy (EPL) at 38%, ring-fenced Corporation Tax at 30%, the Supplementary Charge of 10% and the application of investment allowances. In addition, the tax provision is prepared before the relevant companies have filed their tax returns with the relevant tax authorities and, significantly, before these have been agreed. As a result of these factors, the tax provision process necessarily involves the use of a number of judgements and estimates, including those required in calculating the effective tax rate. The Group recognises deferred tax assets on unused tax losses where it is probable that future taxable profits will be available for utilisation. This requires management to make judgements and assumptions regarding the likelihood of future taxable profits and the amount of deferred tax that can be recognised. Further details regarding the estimated value and related inputs are set out in note 28. The Group\u2019s deferred tax assets are recognised to the extent that taxable profits are expected to arise in the future against which tax losses and allowances in the UK can be utilised, including as a result of Group re-organisations and asset transfers. In accordance with IAS 12 Income Taxes, the Group assesses the recoverability of its deferred tax assets at each period end. Consistent with the impairment sensitivity described above, as at 31 December 2025, a 20% reduction in future revenues, with all other assumptions held constant, would eliminate current headroom and result in deferred tax asset derecognition of $145 million (2024: $284 million). In such a scenario, the Group would also expect the Energy Security Investment Mechanism to be triggered thereby causing the EPL to be switched off early resulting in a reduction in the associated EPL deferred tax liability. The $145 million (2024: $284 million) derecognition assume that cash flows are equivalent to taxable profits and that any reorganisation required to utilise certain deferred tax asset does not result in a displacement of other balances. As disclosed in note 28, there are unrecognised allowances of up to circa $64 million (2024: circa $147 million) that have no expiry date and could be recognised in future periods if future revenue from oil and gas activities increases and/or further actions are undertaken. Other areas of estimation The key assumptions concerning the future, and other sources of estimation uncertainty at the reporting period, that are not expected to cause a material adjustment to the carrying amounts of assets and liabilities within the next financi year, are discussed below: Business combinations During both 2024 and 2025, the Group has made material business combinations \u2013 see note 17 for further details of the provisional purchase price allocations, including the assets and liabilities acquired and the goodwill arising on the transactions These have been accounted for as business combinations under IFRS 3. The assets and liabilities identified in the purchase price allocations include oil and gas assets, decommissioning liabilities, deferred tax assets and liabilities, and working capital. The calculations of the fair value of the oil and gas assets acquired requires the Group to estimate the future cash flows expected to arise from the assets of the acquired businesses using discounted cash flow models. Key assumptions and estimates include: commodity prices, discount rates, and oil and gas reserves estimates. See above estimates in the impairment of oil and gas assets and goodwill section and estimates in oil and gas reserves and contingent resources section for further details regarding these assumptions. In addition, the Group has considered the value that a market participant would prescribe to prospective resources in determining the fair value of the oil and gas assets acquired. The fair value of decommissioning provisions reflects historical events that have occurred up to and including the date of the business combination for which a decommissioning obligation exists and future decommissioning expenditure is expected to be incurred. Where the Group acquires a further interest in a field for which it already holds a working interest, the fair value of the decommissioning liabilities would typically be the existing decommissioning provision for that field proportionately adjusted for the change in working interest. In determining the values of the deferred tax assets recognised on business combinations, the Group has also made assumptions in respect of the amount of tax losses brought forward, which will be available to offset against future taxable profits of the Group. Critical accounting judgements The following is the only critical judgement, apart from those involving estimation (which are presented separately above), that the Directors have made in applying the Group\u2019s accounting policies and that has the most significant effect on the amounts recognised in the financial statements. Rosebank carrying value Management has reviewed the pre-tax carrying value of the Rosebank field of $872 million or post-tax $566 million (31 December 2024: pre-tax $617 million or post-tax $304 million). Although the first phase of the Rosebank development had been sanctioned by the NSTA, it was subject to Judicial Review proceedings. On 30 January 2025, the Court of Session ruled that this consent had been unlawfully given in relation to the sanctioning of the Rosebank field development and that a new consent application would be required, which included Scope 3 emissions. It did, however, permit the project to progress as planned whilst this new consent is sought from the Regulators but that no oil could be extracted without this new consent. The revised Environmental Statement has been submitted and we await the next stage of the process. Whilst the outcome of the Judicial Review could be construed as an indicator of impairment, management has no reason to believe that this further consent will not be forthcoming, and further management believe that the most likely outcome will be that the further consent will be granted and that the project will continue progressing as planned with first oil anticipated in the first half of 2027. As a result no impairment charge is required.", "dimensions": { "concept": "ifrs-full:DisclosureOfMaterialAccountingPolicyInformationExplanatory", "language": "en", "entity": "scheme:21380057TNFLXPXBIP34", "period": "2025-01-01T00:00:00/2026-01-01T00:00:00" } }, "fact-442": { "value": "
Basis of measurement
The consolidated financial statements have been prepared on a going concern basis using the historical cost convention,
except for the revaluation of certain financial assets and financial liabilities, under International Financial Reporting
Standards (IFRS), to fair value, including derivative instruments. Historical cost is generally based on the fair value
consideration given in exchange for the assets and liabilities.

Going concern
Management closely monitor the funding position of the Group, including monitoring compliance with covenants and
available facilities to ensure sufficient headroom is maintained to fund operations. Management have considered a
number of risks applicable to the Group that impact on the Group\u2019s ability, and the Parent Company's ability, to continue
as a going concern. Short-term and long-term cash forecasts are prepared on a weekly and quarterly basis respectively,
along with any related sensitivity analysis. This allows proactive management of any business risk including liquidity risk.
The Directors consider the preparation of the financial statements on a going concern basis to be appropriate. This is
due to the following key factors:
\u2022 A well-hedged portfolio over the next 12 months;
\u2022 Reserves Based Lending (RBL) is undrawn providing liquidity headroom of $1,300 million, plus $214 million of cash
at the end of February 2026; and
\u2022 Robust operational performance and a well-diversified portfolio.

The oil and gas price assumptions used in the going concern and viability assessments represent management's current
best estimates of future commodity prices at the date of approval of the Annual Report and Accounts, as supported
by data from third-party analysis, whereas the commodity prices used in impairment testing (see note 19) are based on
market conditions at 31 December 2025.
Owing to the ongoing fluctuations in commodity demand and price volatility, management prepared sensitivity analyses
to the forecasts and applied a number of plausible downside scenarios, including decreases in production of 10%, reduced
sales prices of 20% and increases in operating and capital expenditures of 10%. Management aggregated these scenarios
to create a reasonable combined worst-case scenario. The sensitivity analysis showed that, without any consideration
of the mitigation strategies within management\u2019s control, there was no reasonably possible scenario that would result
in the business being unable to meet its liabilities as they fell due. In addition, reverse stress tests have been performed
reflecting further reductions in commodity prices, prior to any mitigating actions, to determine at what levels prices
would have to reach such that there is no liquidity headroom left. The stress tests demonstrated that the likelihood of
the fall in prices required to cause a liquidity issue is considered sufficiently remote in the context of the mitigation
strategies available to management. The mitigation strategies within the control of management include a reduction in
uncommitted capital expenditure and variable opex savings in the low production scenario. The analysis demonstrated
that the Group would still continue to comply with financial covenants and have sufficient liquidity throughout the
period to 30 June 2027 to continue trading.
Notwithstanding the Group having net current liabilities at 31 December 2025 of $303.9 million (31 December 2024:
$456.5 million), there are sufficient undrawn facilities available to enable current liabilities to be settled as they fall due.
Based on their assessment of the Group\u2019s financial position in the period to 30 June 2027, the Directors believe that
the Group will be able to continue in operational existence for the foreseeable future. Accordingly, they continue to
adopt the going concern basis of accounting in preparing the financial statements.

Impact of climate change on the financial statements and related notes
Judgements in respect of exploration and evaluation assets and estimates made for all other areas in assessing the impact of
climate change and the energy transition
Climate change and the transition to a lower-carbon system were considered in preparing the consolidated financial
statements. These may have the potential for significant impacts on the carrying values of the Group\u2019s assets and liabilities
discussed below as well as on assets and liabilities that may be reflected in the future. There is also the potential for
significant impact on future cash flows. There is generally a high level of uncertainty about the speed and magnitude of
impacts of climate change which, together with limited historical data, provides significant challenges in the preparation
of forecasts and financial plans with a wide range of potential future outcomes.
The Group\u2019s ambition is to have one of the lowest carbon emission portfolios in the UK North Sea and to achieve Net Zero
(whereby the amount of CO
2
added by the Group\u2019s activities is no greater than the amount taken away), on a net equity basis
(by applying the Group\u2019s working interest in each respective asset to the total emissions of that asset), and in respect of Scope
1 and 2 emissions, by 2040, ten years ahead of the North Sea Transition Deal commitment. This will be achieved by optimising
the Group\u2019s current portfolio in the short term and fundamentally transitioning the Group\u2019s portfolio over the medium to long
term whilst maintaining forecast levels of production. Initiatives include, but are not limited to, operational improvements,
offshore electrification, acquisition and investment into lower carbon intensity assets and the eventual cessation of production
of mature fields which have higher carbon intensity. In addition, the Eni UK business combination in 2024 and the Seagull and
Cygnus acquisitions in 2025 have added relatively low emission assets, thereby reducing the carbon footprint of the Group.
Where the Group cannot reduce Scope 1 and Scope 2 emissions, Ithaca Energy will invest in carbon offsets to achieve the
Group\u2019s goal of Net Zero. All new economic investment decisions include estimated costs of the energy transition based on
existing technology and estimated costs of carbon and these opportunities are assessed on their climate impact potential and
alignment with Ithaca Energy\u2019s Net Zero target, taking into account both greenhouse gas volumes and emissions intensity.
Specific considerations of the potential impacts of climate change on significant judgements and estimates used in the
consolidated financial statements are considered below. The items outlined below are likely to manifest themselves over
a number of years and are, therefore, not generally considered to represent 'key sources of estimation uncertainty' as
required by IAS 1 (being those which could have a material impact on the Group\u2019s results in the 12 months following the
date of the consolidated statement of financial position) which are separately disclosed later in this note.
Impairment of goodwill and property, plant and equipment
The energy transition has the potential to significantly impact future commodity and carbon prices in that as the UK and
global energy system decarbonises, reduced demand for oil and gas products in favour of low carbon alternatives could cause
oil and gas prices to fall which would, in turn, affect the recoverable amount of goodwill and property, plant and equipment.
In the current period management\u2019s estimate of the long-term commodity price assumptions are, in nominal terms from
2032, $80/bbl for Brent Crude and 79p/therm for UK NBP gas. Further details of climate change, including a sensitivity
in this area are provided in note 19.
Recoverable values used for impairment testing for all cash-generating units (CGUs) include the estimated cost of UK carbon
emissions allowances in real terms for CO
2
e of \u00a345/tonne, \u00a365/tonne and \u00a380/tonne for 2026, 2027 and 2028 respectively.
The recoverable value of CGU\u2019s may be impacted by future carbon pricing legislation changes, which could increase operating
costs through higher emissions allowances or the introduction of other carbon pricing mechanisms. Electrification of offshore
operations for specific assets is planned in line with the Group\u2019s 2040 Net Zero ambitions and where feasible based on
existing technology and economic value, estimated electrification costs of a market participant are included within the
assessment of the recoverable value of the relevant CGU.
Property, plant and equipment \u2013 depreciation and useful economic lives
The energy transition has the potential to reduce the expected useful economic lives of assets and hence accelerate
depreciation charges. Although no changes have been identified or recognised to date, as noted in the Strategic Report
on page 58, it is anticipated that certain higher emission-intensity assets such as FPF-1 and Alba will cease production
in the short to medium term and will be replaced by new lower-emission intensity assets. Management does not currently
expect the useful economic lives of the Group\u2019s reported property, plant and equipment to significantly change solely as a
result of the energy transition. However, significant capital expenditure is still required for ongoing projects and therefore,
the useful lives of future capital expenditure may be different.
Intangible assets \u2013 exploration and evaluation assets
The impacts of climate change and the energy transition may affect the viability of exploration prospects, for example, due to
the impact on future commodity and carbon prices (as explained above) or due to the increased risk of regulatory challenge
as prospects progress through to development. The recoverability of the existing intangibles was considered during 2025,
however, no significant write-offs were identified as a result of climate change considerations. Viability of these assets will
continue to be assessed on a regular basis.
Decommissioning provisions
Most of the Group\u2019s existing decommissioning obligations are estimated to be completed over the course of the
next 20 years. The impacts of climate change and the energy transition may bring forward the expected timing of
decommissioning activity, increasing the present value of the associated decommissioning provisions. The potential
impact of a reasonably possible acceleration of estimated decommissioning dates, which considers the potential impact
of the energy transition, is considered to be two years. The impact of such an acceleration of cessation of production
across the Group\u2019s producing assets with estimated cessation of production dates from 2028 onwards, would result in
an increase in the decommissioning provision of approximately $109 million (2024: $93 million). The risk in this area
may increase if key assets within the Group\u2019s existing exploration, appraisal and development portfolio proceed to the
production stage, as this is likely to significantly extend the life of the Group\u2019s portfolio, in some cases to 2050 or beyond.
While the pace of the transition to a lower-carbon economy is uncertain, oil and gas demand is expected to remain a key
element of the energy mix for many years based on stated policies, commitments and announced pledges to reduce
emissions. Therefore, given the estimated useful lives of the Group\u2019s oil and gas portfolio, a material adverse change is
not anticipated to the carrying value of the Group\u2019s assets and liabilities in the short term as a result of climate change
and the transition to a lower-carbon economy.

Business combinations
Business combinations are accounted for using the acquisition method. The cost of a business combination is measured
as the fair value of the consideration given for the assets acquired, equity instruments issued and liabilities incurred or
assumed at the date of completion of the business combination. Transaction costs incurred are expensed and included
in administrative expenses. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business
combination are measured initially at their fair values at the date of the business combination. The excess of the cost of
the business combination over the fair value of the Group\u2019s share of the identifiable net assets acquired is recorded as
goodwill. If the cost of the business combination is less than the Group\u2019s share of the net assets acquired, the difference
is recognised directly in the consolidated statement of profit or loss as a gain on bargain purchase.
Goodwill
Capitalisation
Goodwill is initially recognised and measured as set out above. Following initial recognition, goodwill is measured at cost
less any accumulated impairment losses.
In the event of a business combination or acquisition of an interest in a joint operation in which the activity constitutes a
business, as defined in IFRS 3 Business Combinations, the acquisition method of accounting is applied. Goodwill represents
the difference between the aggregate of the fair value of purchase consideration transferred at the acquisition date and
the fair value of the identifiable assets, liabilities and contingent liabilities acquired, less any non-controlling interest.
If, however, the fair value of the purchase consideration transferred is lower than the fair value of the identifiable assets and
liabilities acquired, less non-controlling interest, the difference is recognised in the income statement as negative goodwill.
The Group\u2019s goodwill is related to the requirement to recognise deferred tax for the difference between the assigned fair
values and the related tax base (technical goodwill). The fair value of the Group\u2019s licences are based on post-tax cash flows or
benchmarked multiples. In accordance with IAS 12 paragraphs 15 and 24, a provision is made for deferred tax corresponding
to the difference between the acquisition cost and the transferred tax depreciation basis. The offsetting entry to this
deferred tax is goodwill. Hence, goodwill arises as a technical effect of deferred tax. Impairments are expected to arise as the
deferred tax liability naturally unwinds in the normal course of business. Goodwill is initially measured at cost. Following initial
recognition, goodwill is measured at cost less any accumulated impairment. Goodwill acquired in a business combination is,
from the acquisition date, allocated to each of the Group\u2019s operating segments. This is subsequently tested for impairment
at the Group\u2019s operating segment level based on the aggregation of any headroom arising from asset impairment tests.
Impairment
Goodwill is tested annually for impairment and also when circumstances indicate that the carrying value may be at risk
of being impaired. Impairment is determined for goodwill by assessing the recoverable amount of each CGU or Group of
CGUs to which the goodwill relates. If the recoverable amount of a CGU is less than its carrying amount, the impairment
loss is allocated first to reduce the carrying amount of goodwill allocated to the unit and then to the other assets of the
unit pro-rata based on the carrying amount of each asset in the unit. Any impairment loss is recognised in the consolidated
statement of profit or loss. Impairment losses relating to goodwill cannot be reversed in future periods. The CGU for the
purposes of the goodwill test is the North Sea, i.e. the entire Group portfolio of oil and gas assets (including E&E assets)
which is consistent with the operating segment view of the business.

Impairment
For impairment review purposes the Group\u2019s oil and gas assets are aggregated into CGUs typically on a field-by-field basis
for development and production assets in accordance with IAS 36, and on a North Sea segment basis for exploration
and evaluation assets in accordance with IFRS 6. A review is carried out at each reporting date for any indicators that
the carrying value of the Group\u2019s assets may be impaired.
Such reviews are carried out on a field-by-field basis for both development and production assets and exploration
and evaluation assets. For assets where there are such indicators, an impairment test is carried out on the CGU. The
impairment test involves comparing the carrying value with the recoverable value of an asset. The recoverable amount of
an asset is determined as the higher of its fair value less costs to sell and value in use. If the recoverable amount of an asset
is estimated to be less than its carrying amount, the carrying amount of the asset is reduced to the recoverable amount.
The resulting impairment losses are written off to the consolidated statement of profit or loss. Previously impaired assets
(excluding goodwill) are reviewed for possible reversal of previous impairment at each reporting date. The maximum
possible reversal is capped at the net book value had the asset not been impaired in the past. Where an exploration and
evaluation licence is relinquished, amounts capitalised in respect of the licence are written off to profit or loss in the
period in which the licence is relinquished.

Impairment of financial assets For trade receivables and accrued income, the Group applies a simplified approach in calculating expected credit losses (ECLs). Therefore, the Group does not track changes in credit risk, but instead recognises any material loss allowance based on lifetime ECLs at each reporting date. For all other financial assets, the Group measures the loss allowance using 12-month expected credit losses unless there was a significant increase in credit risk since initial recognition in which case the loss allowance is measured using lifetime expected credit losses. In making this assessment whether the credit risk increased significantly since initial recognition, the Group considers both quantitative and qualitative information that is reasonable and supportable, including historical experience and forward-looking information that is available without undue cost or effort. The Group considers that the credit risk increased significantly since initial recognition when the credit rating changes, the debtor has significant financial difficulty or if there was a breach of contract. For balances that are beyond 30 days overdue it is presumed to be an indicator of a significant increase in credit risk. The Group considers a financial asset in default when contractual payments are 90 days past due. However, in certain cases, the Group may also consider a financial asset to be in default when internal or external information indicates that the Group is unlikely to receive the outstanding contractual amounts in full before taking into account any credit enhancements held by the Group. A financial asset is written off when there is no reasonable expectation of recovering the contractual cash flows. Financial assets written off may still be subject to enforcement activities under the Group\u2019s recovery procedures, taking into account legal advice where appropriate. Any recoveries made are recognised in profit or loss. Impairment For impairment review purposes the Group\u2019s oil and gas assets are aggregated into CGUs typically on a field-by-field basis for development and production assets in accordance with IAS 36, and on a North Sea segment basis for exploration and evaluation assets in accordance with IFRS 6.

Investments
Investments in listed oil and gas shares are initially recorded at cost and are subsequently remeasured on a fair value
through other comprehensive income basis due to an irrevocable designation having been made in this respect.
Interest in joint ventures
Under IFRS 11, joint arrangements are those that convey joint control which exists only when decisions about the
relevant activities require the unanimous consent of the parties sharing control. Investments in joint arrangements are
classified as either joint operations or joint ventures depending on the contractual rights and obligations of each investor.
The Group\u2019s interest in joint operations (e.g. exploration and production arrangements) are accounted for by recognising
its assets (including its proportionate share of assets held jointly), its liabilities (including its proportionate share of liabilities
incurred jointly), its revenue from the sale of its proportionate share of the output arising from the joint operation and
its expenses (including its proportionate share of any expenses incurred jointly).

Revenue
The sale of crude oil, gas or condensate represents a single performance obligation, being the sale of barrels equivalent
on collection of a cargo or on delivery of commodity into an infrastructure. Revenue is accordingly recognised for this
performance obligation when control over the corresponding commodity is transferred to the customer. Revenue is
recognised at a point in time and is measured based on the consideration to which the Group expects to be entitled in a
contract with a customer and excludes amounts collected for third parties. Details of hedging gains and losses presented
in revenue are discussed in the hedging accounting policy set out below.

Foreign currency translation
Items included in these consolidated financial statements are measured using the currency of the primary economic
environment in which the Group and its subsidiaries operate (the functional currency). The consolidated financial
statements are presented in US Dollars, which is the Group\u2019s presentation currency as well as the functional currency of
the Parent Company and each of its subsidiaries. In preparing the financial statements of the Parent and its subsidiaries,
transactions in currencies other than the entity\u2019s functional currency (foreign currencies) are recognised at the rates
of exchange prevailing on the dates of the transactions. At each reporting date, monetary assets and liabilities that are
denominated in foreign currencies are retranslated at the rates prevailing at that date. Non-monetary items carried at fair
value that are denominated in foreign currencies are translated at the rates prevailing at the date when the fair value was
determined. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated.
Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end
exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the statement of
profit or loss.
Exchange differences are recognised in profit or loss in the period in which they arise except for:
\u2022 Exchange differences on foreign currency borrowings relating to assets under construction for future productive
use, which are included in the cost of those assets when they are regarded as an adjustment to interest costs on those
foreign currency borrowings; and

Financial instruments
All financial instruments are initially recognised at fair value on the statement of financial position. Measurement in
subsequent periods is dependent on the classification of the respective financial instrument.
The Group derecognises a financial asset only when the contractual rights to the cash flows from the asset expire,
or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another
entity. The difference between the carrying amount of the financial asset derecognised and the consideration received/
receivable is recognised in profit or loss.
The Group derecognises financial liabilities when, and only when, the Group\u2019s obligations are discharged, cancelled or have
expired. The Group considers whether refinancing arrangements represent settlement of the existing debt and issuance of
a new debt or an exchange or modification of the previous debt. In making this assessment, the Group considers, amongst
other factors, pre-existing early redemption options in the original agreement, the group of lenders to which the new debt
is offered and any preferential terms or rights given to the original lenders. Where the new debt is considered to represent
an arms-length market offering, the issuance of the new debt is viewed as separate from the extinguishment of the old debt
and is treated as the derecognition of the original liability and the recognition of a new liability. The difference between
the carrying amount of the financial liability derecognised and the consideration paid/payable (excluding consideration
payable for fees incurred on the new liability or accrued interest) is recognised in profit or loss.
IFRS 9 classifications
Cash and cash equivalents are classified at amortised cost which equates to its fair value. Accounts receivable and long-term
receivables are classified and carried at amortised cost less expected credit losses. These items have a business model of held to
collect and the terms of the financial instrument meet the classification of solely payments of interest on principle outstanding.
Accounts payable, accrued liabilities, certain other long-term liabilities and borrowings are classified as other financial
liabilities and carried at amortised cost using the effective interest method. Amortised cost is calculated by taking into
account any issue costs, discount or premium. Contingent consideration is measured at fair value though profit or loss.
Although the Group does not intend to trade its derivative financial instruments, they are required to be carried at fair
value with the treatment of fair value movements explained further below.
Transaction costs, presentation and cash flows
Transaction costs that are directly attributable to the acquisition or issue of a financial asset or liability (excluding the
costs directly attributable to the new loan commitment facilities) have been included in the carrying value of the related
financial asset or liability and are amortised to consolidated net earnings over the life of the financial instrument using
the effective interest method.
Directly attributable fees paid on the establishment of new loan commitment facilities are capitalised to the extent that
it is probable that some or all of the facility will be drawn down. These costs are recognised on a systematic basis over
the period the Group is able to draw down. Fees that are calculated based on the usage of the facility (including letter of
credit fees) are expensed as incurred.
Borrowings are presented as non-current when they are not due to be settled within 12 months after the reporting
period or where the Group has the right at the end of the reporting period to defer settlement for at least 12 months
after the reporting period.
Cash flows relating to refinancing are presented in the statement of cash flows on a net basis where that reflects the actual
cash flows received by the Group. The refinancing proceeds in the statement of cash flows are stated after deduction
of fees which were deducted from the amount paid to the Group. Other fees paid on refinancing are presented as a
separate line item within financing activities or within Interest and charges paid in the statement of cash flows.
Impairment of financial assets
For trade receivables and accrued income, the Group applies a simplified approach in calculating expected credit losses
(ECLs). Therefore, the Group does not track changes in credit risk, but instead recognises any material loss allowance
based on lifetime ECLs at each reporting date. For all other financial assets, the Group measures the loss allowance
using 12-month expected credit losses unless there was a significant increase in credit risk since initial recognition in
which case the loss allowance is measured using lifetime expected credit losses.
In making this assessment whether the credit risk increased significantly since initial recognition, the Group considers
both quantitative and qualitative information that is reasonable and supportable, including historical experience and
forward-looking information that is available without undue cost or effort. The Group considers that the credit risk
increased significantly since initial recognition when the credit rating changes, the debtor has significant financial
difficulty or if there was a breach of contract. For balances that are beyond 30 days overdue it is presumed to be an
indicator of a significant increase in credit risk.
The Group considers a financial asset in default when contractual payments are 90 days past due. However, in certain
cases, the Group may also consider a financial asset to be in default when internal or external information indicates
that the Group is unlikely to receive the outstanding contractual amounts in full before taking into account any credit
enhancements held by the Group.
A financial asset is written off when there is no reasonable expectation of recovering the contractual cash flows.
Financial assets written off may still be subject to enforcement activities under the Group\u2019s recovery procedures,
taking into account legal advice where appropriate. Any recoveries made are recognised in profit or loss.
Derivative financial instruments
The Group enters into a variety of derivative financial instruments to manage its exposure to commodity risks, interest
rate and foreign exchange rate risks. These instruments include: commodity swaps, collars and options; foreign exchange
forward contracts and collars; and interest rate swaps. Further details of derivative financial instruments are disclosed in
notes 30 and 31.
Derivatives are recognised initially at fair value at the date a derivative contract is entered into and are subsequently
remeasured to their fair value at each reporting date. The resulting gain or loss on remeasurement of derivatives is
recognised in profit or loss immediately unless the derivative is designated in a hedge relationship and effective as a hedging
instrument, in which event the timing of the recognition in profit or loss depends on the nature of the hedge relationship.
A derivative with a positive fair value is recognised as a financial asset whereas a derivative with a negative fair value is
recognised as a financial liability. Derivatives are not offset in the financial statements unless the Group has both a legally
enforceable right and intention to offset. A derivative is presented as a non-current asset or a non-current liability if the
remaining maturity of the instrument is more than 12 months and it is not due to be realised or settled within 12 months.
Other derivatives maturing in less than 12 months and expected to be realised or settled in less than 12 months are
presented as current assets or current liabilities.
Hedge accounting
The Group designates certain derivatives as hedging instruments in respect of commodity risks in cash flow hedges.
At the inception of the hedge relationship, the Group documents the relationship between the hedging instrument and
the hedged item, along with its risk management objectives and its strategy for undertaking various hedge transactions.
Furthermore, at the inception of the hedge and on an ongoing basis, the Group documents whether the hedging instrument
is highly effective in offsetting changes in fair values or cash flows of the hedged item attributable to the hedged risk.
If a hedging relationship ceases to meet the hedge effectiveness requirement relating to the hedge ratio, but the risk
management objective for that designated hedging relationship remains the same, the Group adjusts the hedge ratio of
the hedging relationship (i.e. rebalances the hedge) so that it meets the qualifying criteria again.
The Group designates only the intrinsic value of option contracts as a hedging instrument, i.e. excluding the time value
of the option. The changes in the fair value of the aligned time value of the option are recognised in other comprehensive
income and accumulated in the cost of hedging reserve. If the hedged item is transaction-related, the time value is
reclassified to profit or loss when the hedged item affects profit or loss. If the hedged item is time period-related, then
the amount accumulated in the cost of hedging reserve is reclassified to profit or loss on a rational basis \u2013 the Group
applies straight-line amortisation. Those reclassified amounts are recognised in profit or loss in the same line as the
hedged item. If the Group expects that some or all of the loss accumulated in the cost of hedging reserve will not be
recovered in the future, that amount is immediately reclassified to profit or loss.
The effective portion of changes in the fair value of derivatives and other qualifying hedging instruments that are designated
and qualify as cash flow hedges is recognised in other comprehensive income and accumulated under the heading of
cash flow hedge reserve, limited to the cumulative change in fair value of the hedged item from inception of the hedge.
The gain or loss relating to the ineffective portion is recognised immediately in profit or loss, and is included in the
'other gains and losses' line item.
Amounts previously recognised in other comprehensive income and accumulated in equity are reclassified to profit or loss in
the periods when the hedged item affects profit or loss, in the same revenue line as the recognised hedged item. However,
when the hedged forecast transaction results in the recognition of a non-financial asset or a non-financial liability, the gains
and losses previously recognised in other comprehensive income and accumulated in equity are removed from equity and
included in the initial measurement of the cost of the non-financial asset or non-financial liability. This transfer does not
affect other comprehensive income. Furthermore, if the Group expects that some or all of the loss accumulated in the
cash flow hedge reserve will not be recovered in the future, that amount is immediately reclassified to profit or loss.
The Group discontinues hedge accounting only when the hedging relationship (or a part thereof) ceases to meet the
qualifying criteria (after rebalancing, if applicable). This includes instances when the hedging instrument expires or is
sold, terminated or exercised. The discontinuation is accounted for prospectively. Any gain or loss recognised in other
comprehensive income and accumulated in cash flow hedge reserve at that time remains in equity and is reclassified
to profit or loss when the forecast transaction occurs. When a forecast transaction is no longer expected to occur,
the gain or loss accumulated in the cash flow hedge reserve is reclassified immediately to profit or loss.
If a hedge of a transaction-related item is discontinued part way through the life of the hedge (e.g. due to early termination
of the swap, hedging resets), but the hedged item is still expected to occur, the amounts deferred in equity would remain
in equity until the earlier of: (i) the hedged transaction occurring; or (ii) expectation that the amount deferred in equity
will not be recovered in the future periods.
Notes 30 and 31 set out details of the fair values of the derivative instruments used for hedging purposes, and movements
in the cash flow hedge reserve and cost of hedging reserve in equity are detailed in note 30.
Borrowing costs
Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, which are assets
that necessarily take a substantial period of time to get ready for their intended use or sale, are added to the cost of those
assets until such time as the assets are substantially ready for their intended use or sale. All other borrowing costs are
expensed as incurred. Borrowing costs directly attributable to E&E assets are not capitalised and are expensed directly
to profit or loss when incurred.

The effective portion of changes in the fair value of derivatives and other qualifying hedging instruments that are designated and qualify as cash flow hedges is recognised in other comprehensive income and accumulated under the heading of cash flow hedge reserve, limited to the cumulative change in fair value of the hedged item from inception of the hedge. The gain or loss relating to the ineffective portion is recognised immediately in profit or loss, and is included in the 'other gains and losses' line item. Amounts previously recognised in other comprehensive income and accumulated in equity are reclassified to profit or loss in the periods when the hedged item affects profit or loss, in the same revenue line as the recognised hedged item. However, when the hedged forecast transaction results in the recognition of a non-financial asset or a non-financial liability, the gains and losses previously recognised in other comprehensive income and accumulated in equity are removed from equity and included in the initial measurement of the cost of the non-financial asset or non-financial liability. This transfer does not affect other comprehensive income. Furthermore, if the Group expects that some or all of the loss accumulated in the cash flow hedge reserve will not be recovered in the future, that amount is immediately reclassified to profit or loss. The Group discontinues hedge accounting only when the hedging relationship (or a part thereof) ceases to meet the qualifying criteria (after rebalancing, if applicable). This includes instances when the hedging instrument expires or is sold, terminated or exercised. The discontinuation is accounted for prospectively. Any gain or loss recognised in other comprehensive income and accumulated in cash flow hedge reserve at that time remains in equity and is reclassified to profit or loss when the forecast transaction occurs. When a forecast transaction is no longer expected to occur, the gain or loss accumulated in the cash flow hedge reserve is reclassified immediately to profit or loss. If a hedge of a transaction-related item is discontinued part way through the life of the hedge (e.g. due to early termination of the swap, hedging resets), but the hedged item is still expected to occur, the amounts deferred in equity would remain in equity until the earlier of: (i) the hedged transaction occurring; or (ii) expectation that the amount deferred in equity will not be recovered in the future periods.

Contingent and deferred consideration
Contingent consideration in relation to a business combination or asset acquisition is accounted for as a financial liability
and measured at fair value at the date of acquisition with any subsequent remeasurements recognised in profit or loss in
accordance with IFRS 9. These fair values are generally based on risk-adjusted future cash flows discounted using appropriate
discount rates. Changes in fair value of the contingent consideration that qualify as measurement period adjustments are
adjusted retrospectively, with corresponding adjustments against goodwill. Measurement period adjustments are adjustments
that arise from additional information obtained during the 'measurement period' (which cannot exceed one year from the
date of the business combination) about facts and circumstances that existed at the date of the business combination.
The subsequent accounting for changes in the fair value of the contingent consideration that do not qualify as measurement
period adjustments depends on how the contingent consideration is classified. Contingent consideration that is classified
as equity is not remeasured at subsequent reporting dates and its subsequent settlement is accounted for within equity.
Other contingent consideration is remeasured to fair value at subsequent reporting dates with changes in fair value
recognised in profit or loss.
Deferred consideration is measured at amortised cost because the amount payable in the future is fixed.
Settlement of contingent consideration is recorded as investing outflows in the cash flow statement to the extent that
cumulative amounts paid do not exceed the amount recognised at the date of acquisition, with any excess recorded as
an operating cash outflow. Settlement of deferred consideration is recorded as either an investing or financing outflow
in the cash flow statement, depending on the substance of the arrangement at inception. Key considerations in forming
this judgement will include the extent of inferred financing costs included in the overall consideration arrangements at
acquisition, the period of time over which the payments are made, the rationale for agreeing to defer elements of the
consideration and the general level of funding resources available to the Group at the time of acquisition.

Exploration and evaluation assets
Oil and gas expenditure \u2013 exploration and evaluation (E&E) assets
Geological and geophysical costs and costs incurred pre-licence are expensed as incurred. Costs directly associated
with an exploration well are initially capitalised as an intangible asset until the drilling of the well is complete and the
results have been evaluated. These costs include employee remuneration, materials and fuel used, freight costs and
payments made to contractors. If potentially commercial quantities of hydrocarbons are not found, the exploration
well costs are written off. If hydrocarbons are found and, subject to further appraisal activity, are likely to be capable
of commercial development, the costs continue to be carried as an asset. If it is determined that development will not
occur, that is, the efforts are not successful, then the costs are expensed.
Costs directly associated with appraisal activity undertaken to determine the size, characteristics and commercial
potential of a reservoir following the initial discovery of hydrocarbons, including the costs of appraisal wells where
hydrocarbons were not found, are initially capitalised as an intangible asset. Upon external approval for development and
recognition of proved or sanctioned probable reserves, the relevant expenditure is first assessed for impairment and, if
required, an impairment loss is recognised. The remaining balance is then transferred to development and production
(D&P) assets. If development is not approved and no further activity is expected to occur, then the costs are expensed.
The determination of whether potentially economic oil and natural gas reserves have been discovered by an exploration
well is usually made within one year of well completion, but can take longer, depending on the complexity of the geological
structure. Exploration wells that discover potentially economic quantities of oil and natural gas in areas where major
capital expenditure (e.g. an offshore platform or a pipeline) would be required before production could begin and where
the economic viability of that major capital expenditure depends on the successful completion of further exploitation or
appraisal work in the area remain capitalised on the balance sheet as long as such work is under way or firmly planned.

Capitalisation
Costs of bringing a field into production, including the cost of facilities, wells and subsea equipment, direct costs including
staff costs together with E&E assets reclassified in accordance with the above policy, are capitalised as a D&P asset.
Normally each individual field development will form an individual D&P asset but there may be cases, such as phased
developments, or multiple fields around a single production facility when fields are grouped together to form a single
D&P asset.
Depreciation
All costs relating to a development are accumulated and not depreciated until the commencement of production.
Depreciation is calculated on a unit of production basis based on the proved and probable reserves of the asset generally
on a field-by-field basis. Any re-assessment of reserves affects the depreciation rate prospectively. Significant items of
plant and equipment will normally be fully depreciated over the life of the field. However, these items are assessed to

Decommissioning liabilities
The Group records the present value of legal obligations associated with the retirement of long-term tangible assets,
such as producing well sites and processing plants, in the period in which they are incurred with a corresponding increase
in the carrying amount of the related long-term asset. Liabilities for decommissioning are recognised when the Group
has an obligation to plug and abandon a well, dismantle and remove a facility or an item of plant and restore the site
on which it is located, and when a reliable estimate can be made. Where the obligation exists for a new facility or well,
such as oil and gas production or transportation facilities, the obligation generally arises when the asset is installed or
the ground/environment is disturbed at the field location. In subsequent periods, the asset is adjusted for any changes
in the estimated amount or timing of the settlement of the obligations. The amount recognised is the present value
of the estimated future expenditure determined in accordance with local conditions and requirements. Changes in
decommissioning cost estimates for assets that have either been fully written off or have ceased production are expensed
as impairment charges in the period the change occurs. The carrying amounts of the associated decommissioning assets
are depleted using the unit of production method in accordance with the depreciation policy for development and
production assets. Actual costs to retire tangible assets are deducted from the liability as incurred. The unwinding of
discount in the net present value of the total expected cost is treated as an interest expense. Changes in the estimates
are reflected prospectively over the remaining life of the field.
Where some or all of the expenditure required to settle a provision is expected to be reimbursed by another party, a
reimbursement asset is recognised when, and only when, it is virtually certain that reimbursement will be received if the
entity settles the obligation. The amount recognised for the reimbursement may not exceed the amount of the provision.

Taxation
Current tax
Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the
taxation authorities. The tax rates and tax laws used to compute the amounts are those that are enacted or substantively
enacted by the reporting date. Taxable profit differs from net profit, as reported in the consolidated statement of profit
or loss, because it excludes items of income or expense that are taxable or deductible in other accounting periods and it
further excludes items of income or expenses that are never taxable or deductible.
Deferred tax
Deferred tax is recognised using the liability method, providing for temporary differences arising between the tax bases
of assets and liabilities and their carrying amounts in the financial statements. Deferred tax is measured at the tax rates
that are expected to be applied to the temporary differences when they are forecast to reverse, based on the laws that
have been enacted or substantively enacted at each balance sheet date. Details of changes in EPL and other tax matters
are set out in note 28. Deferred tax liabilities are not recognised if they arise from the initial recognition of goodwill and
deferred tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than
business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred
tax assets are recognised only to the extent that it is probable that future taxable profits will be available against which
the temporary differences can be utilised. The carrying amount of deferred tax assets is reviewed at each balance sheet
date and all available evidence is considered in evaluating the recoverability of these deferred tax assets. Deferred tax
assets and liabilities are offset where there is a legally enforceable right to offset current tax assets and liabilities relating
to taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there
is an intention to settle the balances on a net basis.
Deferred Petroleum Revenue Tax (PRT) assets are recognised where PRT relief on future decommissioning costs is probable.

Leases
The Group assesses at contract inception all arrangements to determine whether it is, or contains, a lease. That is, if the
contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.
The Group is not a lessor in any transactions, it is only a lessee. The Group recognises a right-of-use asset and a
corresponding lease liability with respect to all lease arrangements in which it is the lessee. The Group has elected
to apply Paragraph 6 of IFRS 16 to short-term leases (defined as leases with a lease term of 12 months or less) and
leases of low-value assets (such as tablets and personal computers, small items of office furniture and telephones).
Lease payments associated with these leases are expensed over the relevant lease term.
Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for
any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognised,
initial direct costs incurred and lease payments made at or before the commencement date less any lease incentives
received. The right-of-use asset is depreciated over the useful life of the asset.
The Group\u2019s right-of-use assets are included in property, plant and equipment (note 15).
At the commencement date of the lease, the Group recognises lease liabilities measured at the present value of lease payments
to be made over the lease term. In calculating the present value of lease payments, the Group uses its incremental borrowing
rate at the lease commencement date because the interest rate implicit in the lease is generally not readily determinable. After
the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the
lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change
in the lease term, a change in the lease payments (e.g. changes to future payments resulting from a change in an index or
rate used to determine such lease payments) or a change in the assessment of an option to purchase the underlying asset.
The Group has elected to apply the practical expedient under IFRS 16.15 to account for lease and associated non-lease
components as a single lease component on a class-of-asset basis.

Non-GAAP measures
In measuring the Group\u2019s adjusted operating performance, additional financial measures derived from the reported
results have been used by management in order to eliminate factors which distort year-on-year comparisons. The Group\u2019s
adjusted performance is used to explain year-on-year changes when the effect of certain items is significant, including
impairment charges on oil and gas assets, restructuring costs, business combination costs, one-off finance charges related
to refinancing, the tax effect of these items where applicable and non-cash deferred tax charges on changes to EPL.
Adjusted EBITDAX, adjusted net income, adjusted EPS, unit operating expenditure, leverage ratio, adjusted net debt
and certain other reported metrics are non-GAAP measures that are not specifically defined under IFRS or other
generally accepted accounting principles. Further details are set out on pages 220 to 221.

Critical judgements and key sources of estimation uncertainties
Key sources of estimation uncertainty
The key assumptions concerning the future, and other key sources of estimation uncertainty at the reporting period
that may have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within
the next financial year, are discussed below.
Estimates in oil and gas reserves and contingent resources
The Group\u2019s estimates of oil and gas reserves and contingent resources, and the associated production forecasts, are
used in the impairment testing of property, plant and equipment and goodwill, in the measurement of depletion and
decommissioning provisions, the measurement of certain elements of contingent consideration, the going concern
assessment, the viability assessment and in the determination of whether deferred tax assets are recoverable. The
business of the Group is to enhance hydrocarbon recovery and extend the useful lives of mature and underdeveloped
assets and associated infrastructure in a profitable and responsible manner. Estimates of oil and gas reserves and
contingent resources require significant judgement. Factors such as the availability of geological and engineering
data, reservoir performance data, drilling of new wells and estimates of future oil and gas prices all impact on the
determination of the Group\u2019s estimates of its oil and gas reserves, which could result in different future production
profiles affecting prospectively the discounted cash flows used in impairment testing.
The Group\u2019s estimates of reserves and resource volumes used for accounting purposes are built up from historically-matched
models for operated assets and principally from operators\u2019 estimates for non-operated assets. A review process is undertaken
to compare the results of the Group\u2019s internal estimates to those of an independent consultant to understand any
differences in underlying assumptions to ensure there are no significant unreconciled differences between the estimates.
For the purposes of depletion and decommissioning estimates, the Group uses proved and probable reserves; and
for the purposes of the impairment tests performed and deferred tax asset recoverability, the Group considers the
same proved and probable reserves as well as risked resource volumes. These risking adjustments are reflective of
management\u2019s assessment of technical and commercial factors that reflect the value considerations of a market
participant. Changes in estimates of oil and gas reserves and resources resulting in different future production profiles
will affect the discounted cash flows used in impairment testing, the anticipated date of decommissioning, the depletion
charges in accordance with the unit of production method and the recoverability of deferred tax assets. The sensitivity
of the Group\u2019s impairment tests and deferred tax recoverability assessments to key sources of estimation uncertainty,
including reserves and resources, is discussed below.
Estimates in impairment of oil and gas assets and goodwill
Determination of whether the Group\u2019s oil and gas assets (note 15) or goodwill (note 18) have suffered any impairment
requires an estimation of the recoverable amount of the CGU to which oil and gas assets and goodwill have been
allocated. Projected future cash flows are used to determine a fair value less cost to sell to establish the recoverable
amount. Key assumptions and estimates in the impairment models relate to: commodity prices that are based on an
external view of forward curve prices that are considered to be a best estimate of what a market participant would use;
discount rates which reflect management\u2019s estimate of a market participant post-tax weighted average cost of capital;
and oil and gas reserves and resources on a risked basis as described above. Management\u2019s estimates of a market
participant\u2019s view of pricing and discount rates are supplied by an independent consultant.
The sensitivity of the Group\u2019s carrying amounts to these assumptions is illustrated by the impairments and reversals
disclosed in note 19, and by the sensitivity disclosures in note 19. Sensitivity disclosures include, in particular, the impact
of a 20% reduction in forecast revenues.
Contingent consideration
Liabilities for contingent consideration have been recognised on certain business combinations, which are measured
at fair value at acquisition and remeasured at fair value through profit and loss at each reporting date. The amounts of
contingent consideration ultimately payable depend on several factors, including the progress of certain of the oil and
gas properties acquired and the achievement of certain production and commodity price thresholds. Management has
estimated the fair value as the aggregate value of each element of the contingent consideration in each case using an
appropriate valuation technique, taking into account the likelihood of occurrence of each contingent event and the net
present value of the amount potentially payable.
Where applicable, risking assumptions applied in the measurement of contingent consideration were consistent with
those applied in the fair valuation of the related oil and gas properties. A 20% decrease in the probability of a trigger
event occurring and hence a payment being due, with all other assumptions held constant, would result in a decrease
in contingent consideration of $81.8 million (2024: $84.2 million). Whereas a 20% increase in probability of a trigger
event occurring, with all other assumptions held constant, would result in an increase in contingent consideration of
$64.1 million (2024: $77.1 million).
Decommissioning provision estimates
Amounts used in recording a provision for decommissioning are estimates based on current legal and constructive
requirements and current technology and price levels for the removal of facilities and plugging and abandoning of wells.
Due to changes in relation to these items, the future actual cash outflows in relation to decommissioning are likely to
differ in practice. To reflect the effects due to changes in legislation, requirements, technology and price levels, the
carrying amounts of decommissioning provisions are reviewed on a regular basis. The effects of changes in estimates do
not give rise to prior year adjustments and are dealt with prospectively. For operated assets, cost estimates are based on
management\u2019s assessment of work programmes (including durations) and supply chain conditions including, amongst
other factors, applicable vessel and rig rates and durations. For non-operated assets, cost estimates are arrived at by
management\u2019s review of the basis of estimates as provided by the respective operators.
While the Group uses its best estimates and judgement, actual results could differ from these estimates. Expected timing
of expenditure can also change, for example, in response to changes in laws and regulations or their interpretation, and/
or due to changes in commodity prices. The payment dates are uncertain and depend on the production lives of the
respective fields. Management does not expect any reasonable change in the expected timing of decommissioning to
have a material effect on the decommissioning provisions, assuming cash flows remain unchanged. Decommissioning
costs are expected to be incurred over the next 40 years. The Group uses a nominal discount rate of 3.74% for the
first five years and 4.75% thereafter (31 December 2024: 4.38% for the first five years and 4.86% thereafter), based
on the average risk-free rate over the second half of 2025, to discount the estimated costs. The inflation rate applied to
estimated costs is 2.0% (2024: 2.0%). A reduction or an increase in this discount rate of 1% would increase or reduce
the decommissioning liabilities by approximately $300 million or $260 million, respectively (2024: $288 million or
$247 million, respectively), and is not expected to have a material impact on the corresponding decommissioning
reimbursement asset. For further details regarding the estimated value, inputs and assumptions refer to note 23.
Given the large number of variables involved, management consider that it is not practical to provide sensitivities for the
various other individual assumptions but the aggregated impact of related changes in the next 12 months could be material.
Taxation estimates
The Group\u2019s operations are subject to a number of specific tax rules which apply to exploration, development and
production companies such as the Energy Profits Levy (EPL) at 38%, ring-fenced Corporation Tax at 30%, the
Supplementary Charge of 10% and the application of investment allowances. In addition, the tax provision is prepared
before the relevant companies have filed their tax returns with the relevant tax authorities and, significantly, before
these have been agreed. As a result of these factors, the tax provision process necessarily involves the use of a number
of judgements and estimates, including those required in calculating the effective tax rate. The Group recognises
deferred tax assets on unused tax losses where it is probable that future taxable profits will be available for utilisation.
This requires management to make judgements and assumptions regarding the likelihood of future taxable profits and
the amount of deferred tax that can be recognised. Further details regarding the estimated value and related inputs are
set out in note 28.
The Group\u2019s deferred tax assets are recognised to the extent that taxable profits are expected to arise in the future against which tax losses and allowances in the UK can be utilised, including as a result of Group re-organisations and asset transfers. In accordance with IAS 12 Income Taxes, the Group assesses the recoverability of its deferred tax assets at each period end. Consistent with the impairment sensitivity described above, as at 31 December 2025, a 20% reduction in future revenues, with all other assumptions held constant, would eliminate current headroom and result in a deferred tax asset derecognition of $145 million (2024: $284 million). In such a scenario, the Group would also expect the Energy Security Investment Mechanism to be triggered thereby causing the EPL to be switched off early resulting in a reduction in the associated EPL deferred tax liability. The $145 million (2024: $284 million) derecognition assume s that cash flows are equivalent to taxable profits and that any reorganisation required to utilise certain deferred tax asset s does not result in a displacement of other balances. As disclosed in note 28, there are unrecognised allowances of up to circa $64 million (2024: circa $147 million) that have no expiry date and could be recognised in future periods if future revenue from oil and gas activities increases and/or further actions are undertaken. Other areas of estimation The key assumptions concerning the future, and other sources of estimation uncertainty at the reporting period, that are not expected to cause a material adjustment to the carrying amounts of assets and liabilities within the next financi al year, are discussed below: Business combinations During both 2024 and 2025, the Group has made material business combinations \u2013 see note 17 for further details of the provisional purchase price allocations, including the assets and liabilities acquired and the goodwill arising on the transactions . These have been accounted for as business combinations under IFRS 3. The assets and liabilities identified in the purchase price allocations include oil and gas assets, decommissioning liabilities, deferred tax assets and liabilities, and working capital. The calculations of the fair value of the oil and gas assets acquired requires the Group to estimate the future cash flows expected to arise from the assets of the acquired businesses using discounted cash flow models. Key assumptions and estimates include: commodity prices, discount rates, and oil and gas reserves estimates. See above estimates in the impairment of oil and gas assets and goodwill section and estimates in oil and gas reserves and contingent resources section for further details regarding these assumptions. In addition, the Group has considered the value that a market participant would prescribe to prospective resources in determining the fair value of the oil and gas assets acquired. The fair value of decommissioning provisions reflects historical events that have occurred up to and including the date of the business combination for which a decommissioning obligation exists and future decommissioning expenditure is expected to be incurred. Where the Group acquires a further interest in a field for which it already holds a working interest, the fair value of the decommissioning liabilities would typically be the existing decommissioning provision for that field proportionately adjusted for the change in working interest. In determining the values of the deferred tax assets recognised on business combinations, the Group has also made assumptions in respect of the amount of tax losses brought forward, which will be available to offset against future taxable profits of the Group.
Critical accounting judgements
The following is the only critical judgement, apart from those involving estimation (which are presented separately
above), that the Directors have made in applying the Group\u2019s accounting policies and that has the most significant
effect on the amounts recognised in the financial statements.
Rosebank carrying value
Management has reviewed the pre-tax carrying value of the Rosebank field of $872 million or post-tax $566 million
(31 December 2024: pre-tax $617 million or post-tax $304 million). Although the first phase of the Rosebank
development had been sanctioned by the NSTA, it was subject to Judicial Review proceedings. On 30 January 2025,
the Court of Session ruled that this consent had been unlawfully given in relation to the sanctioning of the Rosebank field
development and that a new consent application would be required, which included Scope 3 emissions. It did, however,
permit the project to progress as planned whilst this new consent is sought from the Regulators but that no oil could
be extracted without this new consent. The revised Environmental Statement has been submitted and we await the
next stage of the process. Whilst the outcome of the Judicial Review could be construed as an indicator of impairment,
management has no reason to believe that this further consent will not be forthcoming, and further management believe
that the most likely outcome will be that the further consent will be granted and that the project will continue progressing
as planned with first oil anticipated in the first half of 2027. As a result no impairment charge is required.

Estimates in oil and gas reserves and contingent resources The Group\u2019s estimates of oil and gas reserves and contingent resources, and the associated production forecasts, are used in the impairment testing of property, plant and equipment and goodwill, in the measurement of depletion and decommissioning provisions, the measurement of certain elements of contingent consideration, the going concern assessment, the viability assessment and in the determination of whether deferred tax assets are recoverable. The business of the Group is to enhance hydrocarbon recovery and extend the useful lives of mature and underdeveloped assets and associated infrastructure in a profitable and responsible manner.

For the purposes of depletion and decommissioning estimates, the Group uses proved and probable reserves; and for the purposes of the impairment tests performed and deferred tax asset recoverability, the Group considers the same proved and probable reserves as well as risked resource volumes. These risking adjustments are reflective of management\u2019s assessment of technical and commercial factors that reflect the value considerations of a market participant. Changes in estimates of oil and gas reserves and resources resulting in different future production profiles will affect the discounted cash flows used in impairment testing, the anticipated date of decommissioning, the depletion charges in accordance with the unit of production method and the recoverability of deferred tax assets. The sensitivity of the Group\u2019s impairment tests and deferred tax recoverability assessments to key sources of estimation uncertainty, including reserves and resources, is discussed below. Estimates in impairment of oil and gas assets and goodwill Determination of whether the Group\u2019s oil and gas assets (note 15) or goodwill (note 18) have suffered any impairment requires an estimation of the recoverable amount of the CGU to which oil and gas assets and goodwill have been allocated. Projected future cash flows are used to determine a fair value less cost to sell to establish the recoverable amount. Key assumptions and estimates in the impairment models relate to: commodity prices that are based on an external view of forward curve prices that are considered to be a best estimate of what a market participant would use; discount rates which reflect management\u2019s estimate of a market participant post-tax weighted average cost of capital; and oil and gas reserves and resources on a risked basis as described above. Management\u2019s estimates of a market participant\u2019s view of pricing and discount rates are supplied by an independent consultant. The sensitivity of the Group\u2019s carrying amounts to these assumptions is illustrated by the impairments and reversals disclosed in note 19, and by the sensitivity disclosures in note 19. Sensitivity disclosures include, in particular, the impact of a 20% reduction in forecast revenues.

A 20% decrease in the probability of a trigger event occurring and hence a payment being due, with all other assumptions held constant, would result in a decrease in contingent consideration of $81.8 million (2024: $84.2 million). Whereas a 20% increase in probability of a trigger event occurring, with all other assumptions held constant, would result in an increase in contingent consideration of $64.1 million (2024: $77.1 million).

5. Revenue and other income
The majority of payment terms are on a specified monthly date, as detailed in the initial contract. Otherwise, payment
is due within 30 days of the invoice date. No significant judgements have been made in determining the timing of
satisfaction of performance obligations, the transaction prices and the amounts allocated to performance obligations.
Other income relates to tariff income receivable in the year.
Revenue from two customers exceeded 10% of the Group\u2019s consolidated revenue arising from hydrocarbon sales for
the year ended 31 December 2025, representing $1,642 million and $1,039 million of revenue, respectively (2024: two
customers representing $1,284 million and $420 million of revenue, respectively). It should be noted that the second largest
customer in both 2025 and 2024 is a related party and further details of related party transactions are set out in note 32.
Revenue from contracts with customers derives largely from customers within a single geographical region, being
the United Kingdom. Revenue from contracts with customers outside of the United Kingdom is immaterial and is,
therefore, not disclosed separately.

The reduction in FV of exploration and evaluation assets relates to the Constellation South and Peach prospects. The increase in the FV of trade and other payables relates to an increase in Non-Operated Joint Venture payables. The reduction in current tax payable is principally due to a reclassification of a deferred tax asset to a current tax asset. The increase in decommissioning provisions is in relation to cost estimate changes for decommissioning work required at the date of acquisition and the increase in other provisions relates to a mismeasurement that existed at the acquisition date. The reductions in deferred tax liabilities and deferred tax assets reflects both the reclassification to current tax described above as well as the reassessment of the tax attributes of the business combination. The acquisition of 100% of JAPEX UK completed on 7 July 2025 for a total consideration of $156.4 million thereby increasing the Group's interest in the Seagull asset from 35.0% to 50.0% and the acquisition of 46.25% of Spirit Energy's interest in the Cygnus field completed on 1 October 2025 for a total consideration of $163.6 million thereby increasing the Group's working interest in the Cygnus field from 38.75% to 85.0%. The business combination in 2024 comprised 100% of each of Eni Elgin/ Franklin Limited, Eni UKCS Limited, Eni Energy E&P Limited and Eni Energy E&P UKCS Limited. From the date of acquisition, JAPEX UK contributed $44.5 million of revenue and $27.7 million of profit before tax and the additional Cygnus interest contributed $57.4 million of revenue and $26.5 million of profit before tax. Had these acquisitions completed 1 January 2025, the JAPEX UK acquisition would have contributed $86.7 million of revenue and $45.6 million of profit before tax and the Cygnus acquisition would have contributed $282.7 million of revenue and $173.4 million of profit before tax for the 2025 financial year. In the year to 31 December 2024, from the date of the business combination, the Eni UK businesses contributed $290.1 million of revenue and $195.0 million of profit before tax. Had this business combination completed on 1 January 2024, the Eni UK businesses would have contributed $1,014.0 million of revenue and $598.4 million of profit before tax for the 2024 financial year. Business combination-related costs of $0.3 million (2024: $16.3 million), comprising professional fees and other direct costs, were incurred in the year to 31 December 2025 and are included within 'administrative expenses' in note 7. The fair values of the oil and gas assets and the intangible assets of the business combinations have been determined using valuation techniques based on discounted cash flows using forward curve commodity prices and estimates of long-term commodity prices reflective of market conditions at the completion dates, a discount rate based on observable market data and cost and production profiles generally consistent with the proved and probable reserves acquired with each asset. The decommissioning liabilities recognised have been estimated based on internal engineering estimates for operated assets and operator cost estimates for non-operated assets, with reference to observable market data. The goodwill of $152.2 million in the year to 31 December 2025 (2024: $402.7 million) arises principally from the requirement to recognise deferred tax assets and liabilities for the difference between the assigned fair values and the tax bases of the acquired assets and liabilities assumed in a business combination including, where applicable, capital allowance recognition between the effective date and the completion date under the terms of the SPA. The assessment of fair values of oil and gas assets acquired is based on cash flows after tax. Nevertheless, in accordance with IAS 12 Income Taxes, paragraphs 15 and 19, a provision is made for deferred tax corresponding to the tax rate multiplied by the difference between the acquisition cost and the tax base. The offsetting entry to this deferred tax is goodwill. Hence, goodwill arises as a technical effect of deferred tax (technical goodwill). There are no specific IFRS guidelines pertaining to the allocation of technical goodwill and management has therefore applied the general guidelines for allocating goodwill. Technical goodwill is allocated by segment, in line with where it arises, and none is expected to be deductible for income tax purposes.", "dimensions": { "concept": "ifrs-full:DisclosureOfBusinessCombinationsExplanatory", "language": "en", "entity": "scheme:21380057TNFLXPXBIP34", "period": "2025-01-01T00:00:00/2026-01-01T00:00:00" } }, "fact-517": { "value": "

The goodwill of $784 million at 1 January 2024 relates to historic business combinations comprising principally Chevron
in 2019 and Summit in 2022.
The goodwill on business combinations in 2025 relates to JAPEX UK and Cygnus and in 2024 it relates to the Eni UK
businesses, as detailed in note 17.
The goodwill is not tax deductible on either the JAPEX UK, Cygnus or the Eni UK business combinations.
Goodwill is monitored, and tested for impairment, at the operating segment level, being the North Sea (the entire Group
portfolio of oil and gas assets). This is consistent with the operating segment view of the business, which is presented to the
Board and the Chief Decision Making Officer. The Group\u2019s activities are considered to be an individual operating segment
due to the uniform nature of the Group\u2019s operations within a single geographical area, overseen by the same management and
subject to the same regulations. The fair value estimate is categorised as level 3 in the fair value hierarchy.
Annual impairment tests were performed at both 31 December 2025 and 31 December 2024. These reviews were
carried out on a fair value less cost of disposal basis using risk-adjusted post-tax cash flow projections from the
approved business plans, including the same commodity prices, life of field cost profiles and production volumes
used for impairment of oil and gas assets (see note 19), discounted at a post-tax discount rate of 9.7% (2024: 10.0%).
Assumptions and estimates in the Group impairment models are detailed in note 3. The recoverable amount of the
North Sea CGU at 31 December 2025 was $125 million (2024: $419 million) higher than its carrying amount,
including goodwill, and hence no impairment was recorded (2024: $nil). An increase of 1% in the discount rate would
result in an impairment of $108 million (2024: $nil) to goodwill. Details of further sensitivities are provided in note 19.

The impairment charge on D&P assets of $8.2 million (2024: $148.8 million) relates to an impairment on Alder which ceased production during the year. In the year to 31 December 2024, the $148.8 million impairment comprised a charge for the Greater Stella Area (GSA) of $116.4 million due to a downward revision of reserves, lower gas prices than previously forecast and EPL changes together with a charge of $32.4 million in respect of Pierce due to lower oil prices than previously forecast and EPL changes. Estimated production volumes, supported by third-party analysis, and cash flows used in impairment reviews are considered up to the date of cessation of production on a field-by-field basis, including operating and capital expenditure and are derived from management approved business plans. An impairment review was carried out at the end of 2025 on the Group\u2019s producing assets with the main triggers being lower oil and gas prices. The review was carried out on a fair value less cost of disposal basis using post-tax risk adjusted cash flow projections discounted at a post-tax discount rate of 9.7%, and represents level 3 in the fair value hierarchy. The post-tax recoverable amount for Alder was $nil. The following assumptions were used at Q4 2025 in developing the cash flow model and applied over the expected life of the respective fields:

1 Post-2032, an annual 2% increase is applied to the price assumptions. With all other assumptions held constant, including the cessation of EPL in March 2030, a 20% decrease in the forecast revenues, illustrating a 20% decrease in commodity prices, would result in an additional post-tax impairment to development and production assets of $434 million (2024: $303 million) and a post-tax impairment to exploration and evaluation assets of $nil million (2024: $nil) at 31 December 2025. In addition, under this scenario, goodwill would be impaired in its entirety (2024: goodwill impairment of $929 million). A 20% increase in forecast revenues would not result in any change to the impairment charge in the year ended 31 December 2025 (2024: $24 million post-tax reduction in the impairment charge). An increase or decrease of 1% in the discount rate assumption would not result in a material additional post-tax impairment or reversal of impairment of PP&E. Due to declines in future commodity prices, goodwill headroom reduced to $125 million (2024: $419 million). Commodity prices would have to be 2% lower than the base case scenario for there to be no goodwill headroom left. The Group has also conducted a sensitivity scenario on the climate-related risk of a reduction in demand for oil and gas commodity prices due to changing consumer preferences and/or government regulations. Utilising the Climate Scenario average oil price while maintaining all other parameters in line with the base case, would result in an additional post-tax impairment of PP&E of $nil (2024: $63 million). To calculate the Climate Scenario average oil and gas prices, the Group used data from the International Energy Agency (IEA) climate scenarios (NZ, STEPS, CPS) price assumptions. An impairment review was carried out at the end of 2024 on the Group\u2019s producing assets with the main triggers being lower forward oil and gas prices and changes in EPL legislation. The review was carried out on a fair value less cost of disposal basis using risk adjusted cash flow projections discounted at a post-tax discount rate of 10.0%, and represents level 3 in the fair value hierarchy. The post-tax recoverable amounts for GSA and Pierce were $2 million and $25 million, respectively.

Reserves Based Lending (RBL) facility
During 2024, the Group completed a refinancing of the RBL facility. The RBL facility amount at 31 December 2025
was $1.8 billion (2024: $1.5 billion), consisting of a loan facility of $1,300 million (2024: $1,000 million) and a letter
of credit facility of $500 million (2024: $500 million), with a maturity to 2029, and subject to interest at a reference
rate of SOFR plus 4.0% in years one to four and SOFR plus 4.25% thereafter. At 31 December 2025, the total loan
availability was $1,300 million (2024: $1,000 million), of which $nil (2024: $150 million) was drawn, leaving the full
$1,300 million (2024: $850 million) being available for drawdown. In addition, under the RBL facility, there is an
accordion facility of up to $1,000 million, of which $565 million was committed at 31 December 2025 (2024: $265
million).
Loan fees of $32.4 million relating to the refinancing of the RBL facility were capitalised in the year to 31 December
2024 and are being amortised over the term of the loan. As at 31 December 2025, $27.9 million (2024: $31.2 million)
remains to be amortised.
The obligations of the borrower under the RBL facility are secured by the assets of the guarantor members of the
Group, such as security including share pledges, floating charges and/or debentures. Total assets pledged as security at
31 December 2025 was $8,447 million (2024: $8,275 million).
Covenants under the RBL are detailed below.
Senior notes due 2029
In 2024, the Group completed the refinancing of its senior unsecured notes with the issuance of $750 million 8.125%
senior unsecured notes due October 2029 and repayment in full of the $625 million 9.0% 2026 notes issued during
2021. Loan fees of $17.8 million relating to the senior notes 2029 were capitalised in the year to 31 December 2024
and are being amortised over the life of the loan. Of this amount, $13.8 million (2024: $17.1 million) remains to be
amortised as at 31 December 2025.
In the year to 31 December 2024, the Group received a net cash inflow of $86.8 million from the refinancing of the
senior notes 2029, reflecting senior notes 2029 proceeds of $750.0 million less repayment of senior notes 2026 of
$625.0 million less fees and interest of $38.2 million comprising $14.1 million of early repayment charges and $15.1
million interest on the senior notes due 2026 and $9.0 million of fees in relation to the senior notes due 2029. Fees of
$7.8 million in relation to the new senior notes were paid separately and $1.0 million was accrued at 31 December 2024.
Senior notes due 2031
In 2025, the Group issued \u20ac450 million of 5.50% senior unsecured notes due September 2031. These senior
unsecured notes were swapped to US Dollars at an all-in effective interest rate of approximately 6.7%. Loan fees of
$11.0 million relating to the senior notes 2031 were capitalised and are being amortised over the life of the loan. Of this
amount, $10.5 million (2024: $nil) remains to be amortised as at 31 December 2025.
Project capital expenditure facility
The project capital expenditure facility of up to $150 million relates to a field development. The full amount of this
facility was drawn at 31 December 2025 (2024: $150 million) and it is repayable by instalment expected to be from
2027. Under the terms of the arrangement, interest is payable at a rate of SOFR (subject to a minimum of 5%) plus a
commercially agreed margin.
Covenants
The Group is subject to covenants related to the RBL facility. Failure to meet the terms of one or more of these
covenants may constitute an event of default as defined in the facility agreements, potentially resulting in accelerated
repayment of the debt obligations. The Group was in compliance with all its relevant quarterly financial and operating
covenants during all periods shown for the RBL facility. There are no ongoing maintenance or financial covenant tests
associated with either the 2029 or 2031 senior unsecured notes.
In addition to the below financial covenants, the Group is subject to restrictive covenants under the RBL facility and the
2029 and 2031 notes. These restrictive covenants include restrictions on: making certain payments (including, subject
to certain exceptions, dividends and other distributions); certain activities with respect to outstanding share capital;
repaying or redeeming subordinated debt or share capital; creating or incurring certain liens; making certain acquisitions
and investments or loans; selling, leasing or transferring certain assets including shares of any of the Group\u2019s restricted
subsidiaries; incurring expenditure on exploration and appraisal activities in excess of approved levels; guaranteeing
certain types of the Group\u2019s other indebtedness; expanding into unrelated businesses; merging or consolidating with
other entities; or entering into certain transactions with affiliates.
The key financial covenant and other conditions in the RBL which, if not met, could trigger repayment within 12 months of the reporting date include:
\u2022 As at the end of each 12 month period ending 30 June and 31 December, the ratio of adjusted net debt to adjusted EBITDAX shall be less than 3.5:1. 'Adjusted net debt' referred to is not an IFRS measure. The Group uses adjusted net debt
as a measure to assess its financial position. Adjusted net debt comprises amounts outstanding under the Group\u2019s RBL facility, project capital expenditure facility and senior notes, less cash and cash equivalents;
\u2022 On submission of Corporate Cashflow Projections, total projected sources of funds must exceed the total projected uses of funds for the following 12-month period, or if tested prior to first oil from Rosebank, a period of up to
24 months. Corporate Cashflow Projections must be submitted in June and December each year and on the occurrence of certain events (including on refinancing, when an interest in a petroleum asset is acquired or when certain
distributions are made);
\u2022 The ratio of the net present value of cash flows secured under the RBL for the economic life of the fields to the amount drawn under the facility must not fall below 1.15:1; and
\u2022 The ratio of the net present value of cash flows secured under the RBL for the life of the debt facility to the amount drawn under the facility must not fall below 1.05:1.

Reserves Based Lending (RBL) facility During 2024, the Group completed a refinancing of the RBL facility. The RBL facility amount at 31 December 2025 was $1.8 billion (2024: $1.5 billion), consisting of a loan facility of $1,300 million (2024: $1,000 million) and a letter of credit facility of $500 million (2024: $500 million), with a maturity to 2029, and subject to interest at a reference rate of SOFR plus 4.0% in years one to four and SOFR plus 4.25% thereafter. At 31 December 2025, the total loan availability was $1,300 million (2024: $1,000 million), of which $nil (2024: $150 million) was drawn, leaving the full $1,300 million (2024: $850 million) being available for drawdown. In addition, under the RBL facility, there is an accordion facility of up to $1,000 million, of which $565 million was committed at 31 December 2025 (2024: $265 million). Loan fees of $32.4 million relating to the refinancing of the RBL facility were capitalised in the year to 31 December 2024 and are being amortised over the term of the loan. As at 31 December 2025, $27.9 million (2024: $31.2 million) remains to be amortised. The obligations of the borrower under the RBL facility are secured by the assets of the guarantor members of the Group, such as security including share pledges, floating charges and/or debentures. Total assets pledged as security at 31 December 2025 was $8,447 million (2024: $8,275 million). Covenants under the RBL are detailed below. Senior notes due 2029 In 2024, the Group completed the refinancing of its senior unsecured notes with the issuance of $750 million 8.125% senior unsecured notes due October 2029 and repayment in full of the $625 million 9.0% 2026 notes issued during 2021. Loan fees of $17.8 million relating to the senior notes 2029 were capitalised in the year to 31 December 2024 and are being amortised over the life of the loan. Of this amount, $13.8 million (2024: $17.1 million) remains to be amortised as at 31 December 2025. In the year to 31 December 2024, the Group received a net cash inflow of $86.8 million from the refinancing of the senior notes 2029, reflecting senior notes 2029 proceeds of $750.0 million less repayment of senior notes 2026 of $625.0 million less fees and interest of $38.2 million comprising $14.1 million of early repayment charges and $15.1 million interest on the senior notes due 2026 and $9.0 million of fees in relation to the senior notes due 2029. Fees of $7.8 million in relation to the new senior notes were paid separately and $1.0 million was accrued at 31 December 2024. Senior notes due 2031 In 2025, the Group issued \u20ac450 million of 5.50% senior unsecured notes due September 2031. These senior unsecured notes were swapped to US Dollars at an all-in effective interest rate of approximately 6.7%. Loan fees of $11.0 million relating to the senior notes 2031 were capitalised and are being amortised over the life of the loan. Of this amount, $10.5 million (2024: $nil) remains to be amortised as at 31 December 2025. Project capital expenditure facility The project capital expenditure facility of up to $150 million relates to a field development. The full amount of this facility was drawn at 31 December 2025 (2024: $150 million) and it is repayable by instalment expected to be from 2027. Under the terms of the arrangement, interest is payable at a rate of SOFR (subject to a minimum of 5%) plus a commercially agreed margin. Covenants The Group is subject to covenants related to the RBL facility. Failure to meet the terms of one or more of these covenants may constitute an event of default as defined in the facility agreements, potentially resulting in accelerated repayment of the debt obligations. The Group was in compliance with all its relevant quarterly financial and operating covenants during all periods shown for the RBL facility. There are no ongoing maintenance or financial covenant tests associated with either the 2029 or 2031 senior unsecured notes. In addition to the below financial covenants, the Group is subject to restrictive covenants under the RBL facility and the 2029 and 2031 notes. These restrictive covenants include restrictions on: making certain payments (including, subject to certain exceptions, dividends and other distributions); certain activities with respect to outstanding share capital; repaying or redeeming subordinated debt or share capital; creating or incurring certain liens; making certain acquisitions and investments or loans; selling, leasing or transferring certain assets including shares of any of the Group\u2019s restricted subsidiaries; incurring expenditure on exploration and appraisal activities in excess of approved levels; guaranteeing certain types of the Group\u2019s other indebtedness; expanding into unrelated businesses; merging or consolidating with other entities; or entering into certain transactions with affiliates. The key financial covenant and other conditions in the RBL which, if not met, could trigger repayment within 12 months of the reporting date include: \u2022 As at the end of each 12 month period ending 30 June and 31 December, the ratio of adjusted net debt to adjusted EBITDAX shall be less than 3.5:1. 'Adjusted net debt' referred to is not an IFRS measure. The Group uses adjusted net debt as a measure to assess its financial position. Adjusted net debt comprises amounts outstanding under the Group\u2019s RBL facility, project capital expenditure facility and senior notes, less cash and cash equivalents; \u2022 On submission of Corporate Cashflow Projections, total projected sources of funds must exceed the total projected uses of funds for the following 12-month period, or if tested prior to first oil from Rosebank, a period of up to 24 months. Corporate Cashflow Projections must be submitted in June and December each year and on the occurrence of certain events (including on refinancing, when an interest in a petroleum asset is acquired or when certain distributions are made); \u2022 The ratio of the net present value of cash flows secured under the RBL for the economic life of the fields to the amount drawn under the facility must not fall below 1.15:1; and \u2022 The ratio of the net present value of cash flows secured under the RBL for the life of the debt facility to the amount drawn under the facility must not fall below 1.05:1. 30. Financial instruments To estimate the fair value of financial instruments, the Group uses quoted market prices when available, or industry accepted third-party models and valuation methodologies that utilise observable market data. In addition to market information, the Group incorporates transaction specific details that market participants would utilise in a fair value measurement, including the impact of non-performance risk. The Group characterises inputs used in determining fair value using a hierarchy that prioritises inputs depending on the degree to which they are observable. However, these fai r value estimates may not necessarily be indicative of the amounts that could be realised or settled in a current market transaction. The three levels of the fair value hierarchy are as follows: \u2022 Level 1 \u2013 inputs represent quoted prices in active markets for identical assets or liabilities (for example, exchange- traded commodity derivatives). Active markets are those in which transactions occur in sufficient frequency and volume to provide pricing information on an ongoing basis. \u2022 Level 2 \u2013 inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, as of the reporting date. Level 2 valuations are based on inputs, including quoted forward prices for commodities, market interest rates and volatility factors, which can be observed or corroborated in the marketplace. The Group obtains information from sources such as the New York Mercantile Exchange and independent price publications. \u2022 Level 3 \u2013 inputs that are less observable, unavailable or where the observable data does not support the majority of the instrument\u2019s fair value. In forming estimates, the Group utilises the most observable inputs available for valuation purposes. If a fair value measurement reflects inputs of different levels within the hierarchy, the measurement is categorised based upon the lowest level of input that is significant to the fair value measurement. The valuation of over-the-counter financial swaps and collars is based on similar transactions observable in active markets or industry standard models that primarily rely on market observable inputs. Substantially all of the assumptions for industry standard models are observable in active markets throughout the full term of the instrument. These are categorised as Level 2. Gains or losses on financial instruments, that are not hedge accounted for, are recorded through the 'other gains\u2019 line in the consolidated statement of profit or loss. Credit valuation adjustments (CVA) and debit valuation adjustments (DVA) are calculated for each trade using two key inputs, being future exposures and credit spreads (incorporating both probability of default and loss given default). Future exposures have been estimated using an expected exposure-based approach over the lifetime of the trades. For the risk associated with counterparties, the credit spread is calculated using market observable credit default spreads. For the own credit risk, the credit spread is calculated using reference to a senior unsecured quoted publicly traded bond of the Group using appropriate tenor adjustments, except for out- of-the-money derivatives with counterparties which are in the Group\u2019s RBL. These derivatives rank higher than those with other counterparties as they are fully secured as part of the RBL agreement. Therefore, for the own risk credit risk adjustment (DVA) it has been estimated that the loss given default is zero and hence there is no DVA recognised for those derivatives which are with counterparties of the RBL. All of the Group\u2019s assets are pledged as security against borrowings.

Level 3 contingent consideration is valued on a discounted cash flow basis with the key inputs being commodity prices, the probability of certain future events occurring (\u2018trigger events\u2019) and the discount rate. The forecast cash flows are discounted at a rate of 6.53% (31 December 2024: 6.33%). Management has considered alternative scenarios to assess the valuation of the contingent consideration including, but not limited to, the key accounting estimate relating to the oil price. A reduction or increase in the price assumptions of 20% are considered to be reasonably possible changes. A 20% reduction in the oil price would result in a decrease in contingent consideration of $nil (31 December 2024: $nil) as the forecast price is already at a level which is lower than the trigger price. A 20% increase in the oil price would lead to an increase in contingent consideration of $nil (31 December 2024: $21.7 million). The following table summarises the sensitivity of the Group\u2019s profit before tax due to changes in the carrying value of level 3 financial instruments at the reporting date resulting from a 20% change in the probability of a trigger event occurring, risking of project and conditions being met for payment of contingent consideration, with all other variables held constant. The impact on equity is the same as the impact on profit before tax.

A 1% increase in discount rate would have the equal but opposite effect to the amounts shown above, on the basis that all other variables remain constant. Financial instruments of the Group consist mainly of cash and cash equivalents, receivables, payables, loans and financial derivative contracts, all of which are included in the financial statements. At 31 December 2025 and 31 December 2024, financial instruments and the carrying amounts reported on the balance sheet approximates the fair values with the exception of borrowings. The carrying amount of borrowing is at amortised cost of $1,421.8 million (2024: $1,024.9 million) and the equivalent fair value is $1,438.3 million (2024: $1,025.5 million) that was categorised as level 3 in the fair value hierarchy level. Equivalent fair value was calculated using discounted cash flow method. The unobservable input is adjustment due to credit risk to risk free rates.

The Group has identified that it is exposed principally to these areas of market risk. i) Commodity risk Commodity price risk related to crude oil prices is the Group\u2019s most significant market risk exposure. Crude oil prices and quality differentials are influenced by worldwide factors such as OPEC actions, political events and supply and demand fundamentals. The Group is also exposed to natural gas price movements on uncontracted gas sales. Natural gas prices, in addition to the worldwide factors noted above, can also be influenced by local market conditions. The Group\u2019s expenditures are subject to the effects of inflation and prices received for the product sold are not readily adjustable to cover any increase in expenses from inflation. The Group may periodically use different types of derivative instruments to manage its exposure to price volatility, thus mitigating fluctuations in commodity-related cash flows. In all periods presented, the Group has designated certain commodity options as a cash flow hedge of highly probable sales. Because the critical terms (i.e. the quantity, maturity and underlying price) of the commodity option and their corresponding hedged items are the same, the Group performs a qualitative assessment of effectiveness and it is expected that the intrinsic value of the commodity option and the value of the corresponding hedged items will systematically change in opposite direction in response to movements in the price of underlying commodity if the price of the commodity increases above the strike price of the derivative. The main source of hedge ineffectiveness in these hedge relationships is the effect of the counterparty and the Group\u2019s own credit risk on the fair value of the option contracts, which is not reflected in the fair value of the hedged item and if the forecast transaction will happen earlier or later than originally expected. There was no hedge ineffectiveness in the current or prior year. The Group\u2019s target is to hedge oil and gas prices up to a maximum of 75% of the next 12 months\u2019 production on a rolling annual basis, up to 50% in the following 12-month period and 25% in the subsequent 12-month period. On a rolling basis, the Group has minimum and maximum hedging requirements under the RBL. The minimum requirements depend on levels of utilisation with reference to the latest borrowing base amount, as follows: \u2022 If drawn amounts under the loan tranche of the RBL are below 10%, no hedging is required; \u2022 If drawn amounts are above 10% but below 50%, the Group is required to hedge no less than 35% for the first 12 months and no less than 20% for the following 12 month period; and \u2022 If drawn amounts are equal to or greater than 50%, the Group is required to hedge no less than 50% for the first 12 months and no less than 30% for the following 12 month period. Maximum hedging volumes are set, on a rolling basis, at 85% for year one, 65% for year two, 50% for year three, 30% for year four and 0% thereafter.

The following table summarises the sensitivity of a 20% decrease in realised commodity prices, with all other variables held constant, of the Group\u2019s profit before tax due to changes in the realised price of reported revenues in the year.

A 20% increase in realised commodity prices would have the equal but opposite effect to the amounts shown above, on the basis that all other variables remain constant. ii) Interest risk The calculation of interest payments for the RBL facility and the optional project capital expenditure facility incorporate SOFR. The Group is, therefore, exposed to interest rate risk to the extent that SOFR may fluctuate. The Group mitigates the risk of SOFR fluctuations by entering into interest rate swaps on floating rates. There were no interest rate financial instruments in place at either 31 December 2025 or 31 December 2024. The following table summarises the sensitivity of an increase of 250 basis points in SOFR, with all other variables held constant, of the Group\u2019s profit before tax due to changes in the carrying value of monetary liabilities at the reporting date.

A decrease in 250 basis points in interest rates would have the equal but opposite effect to the amounts shown above, on the basis that all other variables remain constant. iii) Foreign exchange rate risk The Group is exposed to foreign exchange risks to the extent it transacts in various currencies, while measuring and reporting its results in US Dollars. Since time passes between the recording of a receivable or payable transaction and its collection or payment, the Group is exposed to gains or losses on non-US Dollar amounts and on balance sheet translation of monetary accounts denominated in non-US Dollar amounts due to spot rate fluctuations from year-to-year. As at 31 December 2025, the Group had an average of \u00a325.0 million per quarter hedged at an average forward rate of $1.238:\u00a31 for the period January to December 2026. As at 31 December 2025, the Group had an average of \u00a370.1 million per quarter hedged at an average collar floor of $1.221:\u00a31 and average collar ceiling of $1.267:\u00a31 for the period January 2026 to December 2027. As at 31 December 2024, the Group had an average of \u00a321.3 million per quarter hedged at an average forward rate of $1.273:\u00a31 for the period January to December 2025. As at 31 December 2024, the Group had an average of \u00a349.5 million per quarter hedged at an average collar floor of $1.268:\u00a31 and average collar ceiling of $1.298:\u00a31 for the period January to December 2025. The following table summarises the sensitivity to a reasonably possible change in the US Dollar to Pound Sterling foreign exchange rate, with all other variables held constant, of the Group\u2019s profit before tax due to changes in the carrying value of monetary assets and liabilities at the reporting date. The impact on equity is the same as the impact on profit before tax. The Group\u2019s exposure to foreign currency changes for all other currencies is less significant.

A 10% strengthening of Pounds Sterling against the US Dollar would have had the equal but opposite effect to the amounts shown above, on the basis that all other variables remain constant. The Group\u2019s Pound-Sterling denominated monetary net liabilities at 31 December 2025 were \u00a3107 million (2024: \u00a355 million). iv) Credit risk The majority of the Group\u2019s trade and other receivables are with customers in the oil and gas industry and are subject to normal industry credit risks and are unsecured. Customers of the Group are mainly oil and gas majors with good credit ratings and low credit risk, including bp, Eni and Shell. The Group assesses partners\u2019 creditworthiness before entering into farm-in or joint venture agreements. In the past, the Group has not experienced credit loss in the collection of accounts receivable. As the Group\u2019s exploration, drilling and development activities expand with existing and new joint venture partners, the Group will assess and continuously update its management of associated credit risk and related procedures. The Group regularly monitors all customer receivable balances outstanding in excess of 90 days for ECLs. As at 31 December 2025, substantially all accounts receivables are current, being defined as less than 90 days. The Group has no allowance for doubtful accounts as at 31 December 2025 (31 December 2024: $nil). The Group may be exposed to certain losses in the event that counterparties to derivative financial instruments are unable to meet the terms of the contracts. The Group\u2019s exposure is limited to those counterparties holding derivative contracts with positive fair values at the reporting date and these counterparties represent a very low risk of default. As at 31 December 2025, the Group\u2019s exposure is $nil (31 December 2024: $nil). Credit valuation adjustments (CVA) and debit valuation adjustments (DVA) are calculated for each trade using two key inputs, being future exposures and credit spreads (incorporating both probability of default and loss-given default). Future exposures have been estimated using an expected exposure-based approach over the lifetime of the trades. For the risk associated with counterparties, the credit spread is calculated using market observable credit default spreads. For the own credit risk, the credit spread is calculated using reference to a senior unsecured quoted publicly traded bond of the Group using appropriate tenor adjustments, except for out-of-the-money derivatives with counterparties which are in the Group\u2019s RBL. These derivatives rank higher than those with other counterparties as they are fully secured as part of the RBL agreement. Therefore for the own risk credit risk adjustment (DVA) it has been estimated that the loss given default is zero and hence there is no DVA recognised for those derivatives which are with counterparties of the RBL. The Group also has credit risk arising from cash and cash equivalents held with banks and financial institutions. The maximum credit exposure associated with financial assets is the carrying values. v) Liquidity risk Liquidity risk includes the risk that as a result of its operational liquidity requirements, the Group will not have sufficient funds to settle a transaction on the due date. The Group manages liquidity risk by maintaining adequate cash reserves, banking facilities, and by considering medium and future requirements by continuously monitoring forecast and actual cash flows. The Group considers the maturity profiles of its financial assets and liabilities. As at 31 December 2024 and 2025, substantially all accounts payable are current. As borrowings are linked to SOFR, a spot rate at 31 December 2025 was used to calculate future borrowings cash flows. The following table shows the timing of cash outflows, including future interest, relating to financial liabilities, excluding derivatives, at 31 December 2025:

The following tables set out the details of the Group\u2019s liquidity analysis for its derivative financial instruments based on contractual maturities. The tables have been drawn up based on the undiscounted net cash inflows and outflows on derivative instruments that settle on a net basis, and the undiscounted gross inflows and outflows on those derivatives that require gross settlement. When the amount payable or receivable is not fixed, the amount disclosed has been determined by reference to the projected interest rates as illustrated by the yield curves existing at the reporting date.

vi) Capital management The Group\u2019s objectives when managing capital are to safeguard the Group\u2019s ability to continue as a going concern in order to provide returns to shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital. The Group regularly monitors the capital requirements of the business over the short, medium and long term, in order to enable it to foresee when additional capital will be required. The Group has approval from management to hedge external risks, commodity prices, interest rates and foreign exchange risk. This is designed to reduce the risk of adverse movements in market prices, interest rates and exchange rates eroding the Group\u2019s financial results. 31.

The fair value of commodity derivatives is estimated using a net present value model (commodity swaps) or an appropriate option valuation model (options and collars). These contracts are valued using observable market pricing data including volatilities. A 20% reduction in future commodity prices, with all other assumptions held constant, would result in a decrease in the fair value of derivatives of $353 million (2024: $260 million). A 20% increase in future commodity prices, with all other assumptions held constant, would result in an increase in the intrinsic value of option derivative instruments at 31 December 2025 of $124 million (2024: $113 million). Derivative financial instruments that are with counterparties included within the RBL are subject to Master Netting Agreements, this includes the majority of the Group\u2019s derivative financial instruments as at 31 December 2025 and 2024. The terms of the Master Netting Arrangements create a legally enforceable right of offset that comes into effect only on the occurrence of a specified event of default or termination event or other events not expected to happen in the normal course of business. Although the Group has the ability to net settle certain transactions with certain counterparties where an election has been made, this is not considered to be significant at either 31 December 2025 or 31 December 2024. Accordingly, the Group has not offset any derivatives balances in the statement of financial position in any of the periods presented.

The total future decommissioning liability represents the estimated cost to decommission, in situ or by removal, the Group\u2019s net ownership interest in all wells, infrastructure and facilities, based upon forecast timing in future periods. The Group uses a nominal discount rate of 3.74% for the first five years and 4.75% thereafter (31 December 2024: 4.38% for the first five years and 4.86% thereafter) and an inflation rate of 2.0% (31 December 2024: 2.0%) over the varying lives of the assets to calculate the present value of the decommissioning liabilities. The impact of a change in discount rate is considered in note 3. Revisions to estimates in the years ended 31 December 2025 comprised principally Elgin Franklin, Captain, Heather and Strathspey, J-block and Cygnus. In both 2025 and 2024 revisions to estimates were due to changes in both cost estimates and discount rate assumptions. Additions and revisions to estimates comprise:

Although the Group currently expects to incur decommissioning costs over the next 40 years, it is estimated that approximately 36% (2024: 40%) of the decommissioning liability relates to assets which are expected to cease production in the next five years and includes spend for assets that will be reimbursed (see note 11 for further details). The principal assets where decommissioning activity was ongoing at 31 December 2025 were Alba, Anglia, CMS 111, Elgin Franklin, Greater Stella Area, Heather and Strathspey.", "dimensions": { "concept": "ithacaenergyplc:DisclosureOfDecommissioningLiabilities", "language": "en", "entity": "scheme:21380057TNFLXPXBIP34", "period": "2025-01-01T00:00:00/2026-01-01T00:00:00" } }, "fact-521": { "value": "

sales agreements.
At 31 December 2024, other provisions reflected principally estimated liabilities taken on through the Eni UK
business combination in respect of certain historic gas sales agreements along with the ongoing cost of such gas sales
agreements. It was not anticipated at that time that any part of the liability would be settled within 12 months of the

Cash outflows in the year ended 31 December 2025 of $235.6 million (2024: $23.0 million) are principally in relation to the consideration payable on the Eni UK business combination and the Marubeni deferred consideration. Eni UK Business Combination The deferred consideration at 31 December 2025 was $48.2 million (2024: $204.4 million) discounted at 4.33% (2024: 4.33%). Cygnus acquisition The deferred consideration at 31 December 2025 was $10.5 million (2024: $nil). As this payment is expected to be made early in 2026, this amount has not been discounted. Marubeni The contingent consideration arrangement relating to the Marubeni acquisition depends on whether various milestones in the Sale and Purchase Agreement (SPA) are met as follows: set gross export production volume from Montrose Infill Project Phase 1, set cumulative gross export production volume following Arbroath well reinstatements, set gross export production volume from next new well in the Shaw Field and, an amount payable during the Value Sharing Period (1 January 2022 to 31 December 2024) in relation to sales in excess of a set oil trigger price. The amount payable in relation to sales in excess of a set oil trigger price is capped under the terms of the SPA. The carrying amount at 31 December 2025, discounted at 6.53%, was $84 million (2024: $78 million using a discount rate of 6.33%). The total undiscounted potential consideration as at 31 December 2025 was $225 million (2024: $228 million). Siccar The Siccar acquisition included elements of consideration that are payable depending on whether various milestones of the SPA are met as follows: Final Investment Decision and the associated reserves in respect of the Cambo and Rosebank fields and, an amount paid in relation to sales in excess of a set floor oil price between 1 January 2023 and 31 December 2025. The amount payable in relation to sales in excess of a set oil trigger price is capped under the terms of the SPA. The carrying amount at 31 December 2025, discounted at 6.53% was $130 million (2024: $118 million using a discount rate of 6.33%). The total undiscounted potential consideration as at 31 December 2025 was $285 million (2024: $343 million). Others During the year ended 31 December 2023, the Group acquired a further 30% equity in the Cambo field from Shell. The acquisition included elements of consideration that are payable upon certain events occurring and contingent consideration has been recognised to reflect this. The consideration value equates to $1.50 per barrel of oil equivalent of the P50 resource volumes of the field, and is payable on the earlier of receipt of proceeds of any subsequent sale of a working interest in Cambo by the Group, or first oil. The carrying amount at 31 December 2025, discounted at 6.53%, was $13.8 million (2024: $11.7 million discounted at 6.33%). During the year ended 31 December 2023, the Group acquired 40% equity in the Fotla field from Spirit. The acquisition included elements of consideration that are payable upon certain events occurring and contingent consideration has been recognised to reflect this. The consideration comprises two capped amounts with approximately two-thirds payable on final investment decision and one-third on first production. The carrying amount at 31 December 2025, discounted at 6.53%, was $10.2 million (2024: $9.0 million discounted at 6.33%). During the year ended 31 December 2025, the contingent consideration liability in relation to Strathspey, in accordance with the Sale and Purchase Agreement with Chevron, has reduced by $8.9 million to $14.8 million as a result of changes in variables in the calculation of the liability. The total undiscounted potential consideration of other liabilities as at 31 December 2025 was $80 million (2024: $98 million). Revaluation of contingent consideration in the year to 31 December 2025 resulted in a increase of $13.4 million (2024: decrease of $32.9 million). Details of the valuation of contingent consideration and sensitivities are set out in notes 3 and 30.", "dimensions": { "concept": "ithacaenergyplc:DisclosureOfContingentAndDeferredConsideration", "language": "en", "entity": "scheme:21380057TNFLXPXBIP34", "period": "2025-01-01T00:00:00/2026-01-01T00:00:00" } }, "fact-490": { "value": "27.

The Company is UK tax resident. The effective rate of tax applicable for UK ring fence oil and gas activities in both 2025
and 2024 was 40% (excluding the Energy Profits Levy), consisting of a Ring Fence Corporation Tax rate of 30% and the
supplementary charge of 10%. Items affecting the tax charge include interest income taxed at non-oil and gas tax rate of
25%, true-ups in respect of prior years resulting from filing of prior year tax returns, a 10% uplift on ring fence losses, Ring
Fence Expenditure Supplement increasing the losses available to offset future profits subject to Ring Fence Corporation
Tax and Supplementary Charge. In addition, investment allowance, a 62.5% uplift on capital expenditure, is available reducing
the profits subject to the supplementary charge only. Petroleum Revenue Tax (PRT) is applied at 0% on certain oil and gas fields
in the UK, however, adjustments to recognised deferred PRT assets are made to reflect updated expectations of reversal against
profits subject to the 0% PRT rate. The Energy Profits Levy of 35% originally applied up to 31 March 2028. On 6 March
2024, it was announced that EPL would be extended by one year to 31 March 2029 and on 29 July 2024, it was announced
that there would be a further extension to March 2030 and that the rate would increase from 35% to 38% from 1 November
2024. The impact of this rate increase was a charge to the consolidated statement of profit or loss of $58.1 million in the year to
31 December 2024. The extension to 31 March 2030 was substantively enacted on 3 March 2025 and resulted in a deferred
tax charge of $327.6 million in the year to 31 December 2025. As part of the Autumn 2025 Budget, it was announced that the
EPL would be replaced by a permanent revenue-based oil and gas price mechanism (OGPM). The OGPM will only apply during
periods of high prices and the amount that will be chargeable to the OGPM will be the part of the realised revenue that exceeds
the respective oil and gas thresholds (announced as $90 per barrel for oil and 90p per therm for gas, which are to be adjusted
annually in line with CPI inflation). The mechanism will be implemented in a future Finance Bill and will come into force
on 1 April 2030 or earlier if the energy security investment mechanism is triggered. If the OGPM had been substantively
enacted by the balance sheet date, there would have been no material impact on the financial statements of the Group.
The tax on the Group\u2019s profit before tax differs from the theoretical amount that would arise using the 40% statutory

Deferred tax assets primarily relate to decommissioning liabilities, brought forward tax losses and accumulated losses
and profits related to derivative contracts. Deferred tax liabilities primarily relate to accelerated capital allowances on
property, plant and equipment and accumulated losses and profits related to derivative contracts. Deferred tax balances
are presented net as they arise in the same jurisdiction and the Group has a legally-enforceable right to offset as well as an
intention to settle on a net basis. There are unrecognised deferred tax assets in relation to allowances of up to circa $64
million (2024: circa $147 million) that have no expiry date and could be recognised in future periods if future revenue
from oil and gas activities increases and/or further actions are undertaken. A deferred tax asset of $72 million (2024:
$63 million) associated with non-oil and gas losses, of which there is no expiry date, has not been recognised for deferred
tax purposes as it is not sufficiently certain that there will be future non-oil and gas profits to offset these losses.

The carrying value of the net deferred tax asset (DTA) and the deferred PRT asset at 31 December 2025 of $222
million and $140 million, respectively (2024: $1,082 million and $142 million, respectively), are supported by estimates
of the Group\u2019s future taxable income, based on the same price and cost assumptions as used for impairment testing.
The Group has undertaken and will undertake further restructuring exercises to move certain assets between Group
entities. Existing restructuring exercises have now been substantially completed. The recoverability of the deferred
corporation tax asset is supported by this restructuring. The DTA relating to losses within the Group are expected to
unwind against taxable profits before the end of 2031.
On 20 June 2023, Finance (No. 2) Act 2023 was substantially enacted in the UK, introducing a global minimum
effective tax rate of 15%. The legislation implements a domestic top-up tax and a multinational top-up tax, effective for
all accounting periods starting on or after 31 December 2023. The adoption of this has not had a material impact as the
prevailing rate of tax in the United Kingdom is in excess of the 15% minimum rate. The Group has applied the exemption
under IAS 12 to recognising and disclosing information about deferred tax assets and liabilities related to top-up income
taxes and, therefore, there is no impact on the tax values reported.

The Company is UK tax resident. The effective rate of tax applicable for UK ring fence oil and gas activities in both 2025 and 2024 was 40% (excluding the Energy Profits Levy), consisting of a Ring Fence Corporation Tax rate of 30% and the supplementary charge of 10%. Items affecting the tax charge include interest income taxed at non-oil and gas tax rate of 25%, true-ups in respect of prior years resulting from filing of prior year tax returns, a 10% uplift on ring fence losses, Ring Fence Expenditure Supplement increasing the losses available to offset future profits subject to Ring Fence Corporation Tax and Supplementary Charge. In addition, investment allowance, a 62.5% uplift on capital expenditure, is available reducing the profits subject to the supplementary charge only. Petroleum Revenue Tax (PRT) is applied at 0% on certain oil and gas fields in the UK, however, adjustments to recognised deferred PRT assets are made to reflect updated expectations of reversal against profits subject to the 0% PRT rate. The Energy Profits Levy of 35% originally applied up to 31 March 2028. On 6 March 2024, it was announced that EPL would be extended by one year to 31 March 2029 and on 29 July 2024, it was announced that there would be a further extension to March 2030 and that the rate would increase from 35% to 38% from 1 November 2024. The impact of this rate increase was a charge to the consolidated statement of profit or loss of $58.1 million in the year to 31 December 2024. The extension to 31 March 2030 was substantively enacted on 3 March 2025 and resulted in a deferred tax charge of $327.6 million in the year to 31 December 2025. As part of the Autumn 2025 Budget, it was announced that the EPL would be replaced by a permanent revenue-based oil and gas price mechanism (OGPM). The OGPM will only apply during periods of high prices and the amount that will be chargeable to the OGPM will be the part of the realised revenue that exceeds the respective oil and gas thresholds (announced as $90 per barrel for oil and 90p per therm for gas, which are to be adjusted annually in line with CPI inflation). The mechanism will be implemented in a future Finance Bill and will come into force on 1 April 2030 or earlier if the energy security investment mechanism is triggered. If the OGPM had been substantively enacted by the balance sheet date, there would have been no material impact on the financial statements of the Group. The tax on the Group\u2019s profit before tax differs from the theoretical amount that would arise using the 40% statutory rate of tax applicable for UK ring fence oil and gas activities as follows:

Deferred tax assets primarily relate to decommissioning liabilities, brought forward tax losses and accumulated losses and profits related to derivative contracts. Deferred tax liabilities primarily relate to accelerated capital allowances on property, plant and equipment and accumulated losses and profits related to derivative contracts. Deferred tax balances are presented net as they arise in the same jurisdiction and the Group has a legally-enforceable right to offset as well as an intention to settle on a net basis. There are unrecognised deferred tax assets in relation to allowances of up to circa $64 million (2024: circa $147 million) that have no expiry date and could be recognised in future periods if future revenue from oil and gas activities increases and/or further actions are undertaken. A deferred tax asset of $72 million (2024: $63 million) associated with non-oil and gas losses, of which there is no expiry date, has not been recognised for deferred tax purposes as it is not sufficiently certain that there will be future non-oil and gas profits to offset these losses.

commitments for future capital expenditure amounting to $309 million (2024: $400 million). The key component of
this relates to the Rosebank development at both dates. There are also commitments in relation to AFEs (authorisations
for expenditure) signed for activities on Captain enhanced oil extraction at both dates and commitments for Cygnus
drilling activities at 31 December 2025.
Contingencies
The Group enters into letters of credit and surety bonds to provide security for the Group\u2019s obligations under certain
field and bi-lateral decommissioning security agreements, or equivalent, Sullom Voe Terminal Tariff Agreements
and deferred payment obligations. The instruments are either held by the Law Debenture Trust Corporation P.L.C.
under a trust deed or EnQuest Heather Limited, as SVT Terminal Operator. At 31 December 2025, the Group had
$963 million (31 December 2024: $822 million) in letters of credit and surety bonds outstanding relating to security
obligations under certain decommissioning and security agreements.

30. Financial instruments
To estimate the fair value of financial instruments, the Group uses quoted market prices when available, or industry
accepted third-party models and valuation methodologies that utilise observable market data. In addition to market
information, the Group incorporates transaction specific details that market participants would utilise in a fair value
measurement, including the impact of non-performance risk. The Group characterises inputs used in determining fair
value using a hierarchy that prioritises inputs depending on the degree to which they are observable. However, these fai r
value estimates may not necessarily be indicative of the amounts that could be realised or settled in a current market
transaction. The three levels of the fair value hierarchy are as follows:
\u2022 Level 1 \u2013 inputs represent quoted prices in active markets for identical assets or liabilities (for example, exchange-
traded commodity derivatives). Active markets are those in which transactions occur in sufficient frequency and
volume to provide pricing information on an ongoing basis.
\u2022 Level 2 \u2013 inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, as of the
reporting date. Level 2 valuations are based on inputs, including quoted forward prices for commodities, market interest
rates and volatility factors, which can be observed or corroborated in the marketplace. The Group obtains information
from sources such as the New York Mercantile Exchange and independent price publications.
\u2022 Level 3 \u2013 inputs that are less observable, unavailable or where the observable data does not support the majority of
the instrument\u2019s fair value.
In forming estimates, the Group utilises the most observable inputs available for valuation purposes. If a fair value
measurement reflects inputs of different levels within the hierarchy, the measurement is categorised based upon the
lowest level of input that is significant to the fair value measurement. The valuation of over-the-counter financial swaps
and collars is based on similar transactions observable in active markets or industry standard models that primarily rely
on market observable inputs. Substantially all of the assumptions for industry standard models are observable in active
markets throughout the full term of the instrument. These are categorised as Level 2.
Gains or losses on financial instruments, that are not hedge accounted for, are recorded through the 'other gains\u2019 line
in the consolidated statement of profit or loss. Credit valuation adjustments (CVA) and debit valuation adjustments
(DVA) are calculated for each trade using two key inputs, being future exposures and credit spreads (incorporating both
probability of default and loss given default). Future exposures have been estimated using an expected exposure-based
approach over the lifetime of the trades. For the risk associated with counterparties, the credit spread is calculated
using market observable credit default spreads. For the own credit risk, the credit spread is calculated using reference
to a senior unsecured quoted publicly traded bond of the Group using appropriate tenor adjustments, except for out-
of-the-money derivatives with counterparties which are in the Group\u2019s RBL. These derivatives rank higher than those
with other counterparties as they are fully secured as part of the RBL agreement. Therefore, for the own risk credit risk
adjustment (DVA) it has been estimated that the loss given default is zero and hence there is no DVA recognised for
those derivatives which are with counterparties of the RBL.
All of the Group\u2019s assets are pledged as security against borrowings.

Level 3 contingent consideration is valued on a discounted cash flow basis with the key inputs being commodity prices, the probability of certain future events occurring (\u2018trigger events\u2019) and the discount rate. The forecast cash flows are discounted at a rate of 6.53% (31 December 2024: 6.33%). Management has considered alternative scenarios to assess the valuation of the contingent consideration including, but not limited to, the key accounting estimate relating to the oil price. A reduction or increase in the price assumptions of 20% are considered to be reasonably possible changes. A 20% reduction in the oil price would result in a decrease in contingent consideration of $nil (31 December 2024: $nil) as the forecast price is already at a level which is lower than the trigger price. A 20% increase in the oil price would lead to an increase in contingent consideration of $nil (31 December 2024: $21.7 million). The following table summarises the sensitivity of the Group\u2019s profit before tax due to changes in the carrying value of level 3 financial instruments at the reporting date resulting from a 20% change in the probability of a trigger event occurring, risking of project and conditions being met for payment of contingent consideration, with all other variables held constant. The impact on equity is the same as the impact on profit before tax.

Financial instruments of the Group consist mainly of cash and cash equivalents, receivables, payables, loans and financial derivative contracts, all of which are included in the financial statements. At 31 December 2025 and 31 December 2024, financial instruments and the carrying amounts reported on the balance sheet approximates the fair values with the exception of borrowings. The carrying amount of borrowing is at amortised cost of $1,421.8 million (2024: $1,024.9 million) and the equivalent fair value is $1,438.3 million (2024: $1,025.5 million) that was categorised as level 3 in the fair value hierarchy level. Equivalent fair value was calculated using discounted cash flow method. The unobservable input is adjustment due to credit risk to risk free rates.

(2024: $1,024.9 million) and the equivalent fair value is $1,438.3 million (2024: $1,025.5 million) that was categorised
as level 3 in the fair value hierarchy level. Equivalent fair value was calculated using discounted cash flow method. The
unobservable input is adjustment due to credit risk to risk free rates.

The fair value of commodity derivatives is estimated using a net present value model (commodity swaps) or an
appropriate option valuation model (options and collars). These contracts are valued using observable market pricing
data including volatilities. A 20% reduction in future commodity prices, with all other assumptions held constant, would
result in a decrease in the fair value of derivatives of $353 million (2024: $260 million). A 20% increase in future commodity
prices, with all other assumptions held constant, would result in an increase in the intrinsic value of option derivative
instruments at 31 December 2025 of $124 million (2024: $113 million).
Derivative financial instruments that are with counterparties included within the RBL are subject to Master Netting
Agreements, this includes the majority of the Group\u2019s derivative financial instruments as at 31 December 2025 and 2024.
The terms of the Master Netting Arrangements create a legally enforceable right of offset that comes into effect only on the
occurrence of a specified event of default or termination event or other events not expected to happen in the normal course
of business. Although the Group has the ability to net settle certain transactions with certain counterparties where an election
has been made, this is not considered to be significant at either 31 December 2025 or 31 December 2024. Accordingly, the
Group has not offset any derivatives balances in the statement of financial position in any of the periods presented.

i) Commodity risk
Commodity price risk related to crude oil prices is the Group\u2019s most significant market risk exposure. Crude oil prices
and quality differentials are influenced by worldwide factors such as OPEC actions, political events and supply and
demand fundamentals. The Group is also exposed to natural gas price movements on uncontracted gas sales. Natural
gas prices, in addition to the worldwide factors noted above, can also be influenced by local market conditions. The
Group\u2019s expenditures are subject to the effects of inflation and prices received for the product sold are not readily
adjustable to cover any increase in expenses from inflation. The Group may periodically use different types of derivative
instruments to manage its exposure to price volatility, thus mitigating fluctuations in commodity-related cash flows.
In all periods presented, the Group has designated certain commodity options as a cash flow hedge of highly probable
sales. Because the critical terms (i.e. the quantity, maturity and underlying price) of the commodity option and
their corresponding hedged items are the same, the Group performs a qualitative assessment of effectiveness and
it is expected that the intrinsic value of the commodity option and the value of the corresponding hedged items will
systematically change in opposite direction in response to movements in the price of underlying commodity if the price
of the commodity increases above the strike price of the derivative. The main source of hedge ineffectiveness in these
hedge relationships is the effect of the counterparty and the Group\u2019s own credit risk on the fair value of the option
contracts, which is not reflected in the fair value of the hedged item and if the forecast transaction will happen earlier or
later than originally expected. There was no hedge ineffectiveness in the current or prior year.
The Group\u2019s target is to hedge oil and gas prices up to a maximum of 75% of the next 12 months\u2019 production on a rolling
annual basis, up to 50% in the following 12-month period and 25% in the subsequent 12-month period. On a rolling
basis, the Group has minimum and maximum hedging requirements under the RBL. The minimum requirements
depend on levels of utilisation with reference to the latest borrowing base amount, as follows:
\u2022 If drawn amounts under the loan tranche of the RBL are below 10%, no hedging is required;
\u2022 If drawn amounts are above 10% but below 50%, the Group is required to hedge no less than 35% for the first 12
months and no less than 20% for the following 12 month period; and
\u2022 If drawn amounts are equal to or greater than 50%, the Group is required to hedge no less than 50% for the first 12
months and no less than 30% for the following 12 month period.
Maximum hedging volumes are set, on a rolling basis, at 85% for year one, 65% for year two, 50% for year three, 30%
for year four and 0% thereafter.

The following table summarises the sensitivity of a 20% decrease in realised commodity prices, with all other variables
held constant, of the Group\u2019s profit before tax due to changes in the realised price of reported revenues in the year. The
impact on equity is the same as the impact on profit before tax.

(223.4)
(119.8)
A 20% increase in realised commodity prices would have the equal but opposite effect to the amounts shown above, on
the basis that all other variables remain constant.
ii) Interest risk
The calculation of interest payments for the RBL facility and the optional project capital expenditure facility incorporate
SOFR. The Group is, therefore, exposed to interest rate risk to the extent that SOFR may fluctuate. The Group
mitigates the risk of SOFR fluctuations by entering into interest rate swaps on floating rates.
There were no interest rate financial instruments in place at either 31 December 2025 or 31 December 2024.
The following table summarises the sensitivity of an increase of 250 basis points in SOFR, with all other variables held
constant, of the Group\u2019s profit before tax due to changes in the carrying value of monetary liabilities at the reporting date.
2025 2024

Increase of 250 basis points
(8.4)
(8.4)
A decrease in 250 basis points in interest rates would have the equal but opposite effect to the amounts shown above,
on the basis that all other variables remain constant.
iii) Foreign exchange rate risk
The Group is exposed to foreign exchange risks to the extent it transacts in various currencies, while measuring and reporting
its results in US Dollars. Since time passes between the recording of a receivable or payable transaction and its collection or
payment, the Group is exposed to gains or losses on non-US Dollar amounts and on balance sheet translation of monetary
accounts denominated in non-US Dollar amounts due to spot rate fluctuations from year-to-year.
As at 31 December 2025, the Group had an average of \u00a325.0 million per quarter hedged at an average forward rate
of $1.238:\u00a31 for the period January to December 2026. As at 31 December 2025, the Group had an average of
\u00a370.1 million per quarter hedged at an average collar floor of $1.221:\u00a31 and average collar ceiling of $1.267:\u00a31 for the
period January 2026 to December 2027.
As at 31 December 2024, the Group had an average of \u00a321.3 million per quarter hedged at an average forward rate of
$1.273:\u00a31 for the period January to December 2025. As at 31 December 2024, the Group had an average of \u00a349.5
million per quarter hedged at an average collar floor of $1.268:\u00a31 and average collar ceiling of $1.298:\u00a31 for the period
January to December 2025.
The following table summarises the sensitivity to a reasonably possible change in the US Dollar to Pound Sterling
foreign exchange rate, with all other variables held constant, of the Group\u2019s profit before tax due to changes in the
carrying value of monetary assets and liabilities at the reporting date. The impact on equity is the same as the impact on
profit before tax. The Group\u2019s exposure to foreign currency changes for all other currencies is less significant.
2025 2024
Change in Pounds Sterling foreign exchange rate $m $m
10% weakening of Pounds Sterling against the US Dollar
(14.1)
(6.9)
A 10% strengthening of Pounds Sterling against the US Dollar would have had the equal but opposite effect to the
amounts shown above, on the basis that all other variables remain constant.
The Group\u2019s Pound-Sterling denominated monetary net liabilities at 31 December 2025 were \u00a3107 million
(2024: \u00a355 million).
iv) Credit risk
The majority of the Group\u2019s trade and other receivables are with customers in the oil and gas industry and are subject to
normal industry credit risks and are unsecured. Customers of the Group are mainly oil and gas majors with good credit
ratings and low credit risk, including bp, Eni and Shell.
The Group assesses partners\u2019 creditworthiness before entering into farm-in or joint venture agreements. In the past,
the Group has not experienced credit loss in the collection of accounts receivable. As the Group\u2019s exploration, drilling
and development activities expand with existing and new joint venture partners, the Group will assess and continuously
update its management of associated credit risk and related procedures.
The Group regularly monitors all customer receivable balances outstanding in excess of 90 days for ECLs. As at
31 December 2025, substantially all accounts receivables are current, being defined as less than 90 days. The Group
has no allowance for doubtful accounts as at 31 December 2025 (31 December 2024: $nil).
The Group may be exposed to certain losses in the event that counterparties to derivative financial instruments are
unable to meet the terms of the contracts. The Group\u2019s exposure is limited to those counterparties holding derivative
contracts with positive fair values at the reporting date and these counterparties represent a very low risk of default. As
at 31 December 2025, the Group\u2019s exposure is $nil (31 December 2024: $nil).
Credit valuation adjustments (CVA) and debit valuation adjustments (DVA) are calculated for each trade using two key
inputs, being future exposures and credit spreads (incorporating both probability of default and loss-given default).
Future exposures have been estimated using an expected exposure-based approach over the lifetime of the trades. For
the risk associated with counterparties, the credit spread is calculated using market observable credit default spreads. For
the own credit risk, the credit spread is calculated using reference to a senior unsecured quoted publicly traded bond of the
Group using appropriate tenor adjustments, except for out-of-the-money derivatives with counterparties which are in the
Group\u2019s RBL. These derivatives rank higher than those with other counterparties as they are fully secured as part of the
RBL agreement. Therefore for the own risk credit risk adjustment (DVA) it has been estimated that the loss given default is
zero and hence there is no DVA recognised for those derivatives which are with counterparties of the RBL. The Group also
has credit risk arising from cash and cash equivalents held with banks and financial institutions. The maximum credit
exposure associated with financial assets is the carrying values.
v) Liquidity risk
Liquidity risk includes the risk that as a result of its operational liquidity requirements, the Group will not have sufficient
funds to settle a transaction on the due date. The Group manages liquidity risk by maintaining adequate cash reserves,
banking facilities, and by considering medium and future requirements by continuously monitoring forecast and actual
cash flows. The Group considers the maturity profiles of its financial assets and liabilities. As at 31 December 2024 and
2025, substantially all accounts payable are current. As borrowings are linked to SOFR, a spot rate at 31 December
2025 was used to calculate future borrowings cash flows.

The following tables set out the details of the Group\u2019s liquidity analysis for its derivative financial instruments based on
contractual maturities. The tables have been drawn up based on the undiscounted net cash inflows and outflows on
derivative instruments that settle on a net basis, and the undiscounted gross inflows and outflows on those derivatives
that require gross settlement. When the amount payable or receivable is not fixed, the amount disclosed has been
determined by reference to the projected interest rates as illustrated by the yield curves existing at the reporting date.

vi) Capital management
The Group\u2019s objectives when managing capital are to safeguard the Group\u2019s ability to continue as a going concern in
order to provide returns to shareholders and benefits for other stakeholders and to maintain an optimal capital structure
to reduce the cost of capital. The Group regularly monitors the capital requirements of the business over the short,
medium and long term, in order to enable it to foresee when additional capital will be required.
The Group has approval from management to hedge external risks, commodity prices, interest rates and foreign
exchange risk. This is designed to reduce the risk of adverse movements in market prices, interest rates and exchange
rates eroding the Group\u2019s financial results.

Because the critical terms (i.e. the quantity, maturity and underlying price) of the commodity option and their corresponding hedged items are the same, the Group performs a qualitative assessment of effectiveness and it is expected that the intrinsic value of the commodity option and the value of the corresponding hedged items will systematically change in opposite direction in response to movements in the price of underlying commodity if the price of the commodity increases above the strike price of the derivative. The main source of hedge ineffectiveness in these hedge relationships is the effect of the counterparty and the Group\u2019s own credit risk on the fair value of the option contracts, which is not reflected in the fair value of the hedged item and if the forecast transaction will happen earlier or later than originally expected. There was no hedge ineffectiveness in the current or prior year. The Group\u2019s target is to hedge oil and gas prices up to a maximum of 75% of the next 12 months\u2019 production on a rolling annual basis, up to 50% in the following 12-month period and 25% in the subsequent 12-month period. On a rolling basis, the Group has minimum and maximum hedging requirements under the RBL. The minimum requirements depend on levels of utilisation with reference to the latest borrowing base amount, as follows: \u2022 If drawn amounts under the loan tranche of the RBL are below 10%, no hedging is required; \u2022 If drawn amounts are above 10% but below 50%, the Group is required to hedge no less than 35% for the first 12 months and no less than 20% for the following 12 month period; and \u2022 If drawn amounts are equal to or greater than 50%, the Group is required to hedge no less than 50% for the first 12 months and no less than 30% for the following 12 month period. Maximum hedging volumes are set, on a rolling basis, at 85% for year one, 65% for year two, 50% for year three, 30% for year four and 0% thereafter.

The following table summarises the sensitivity of a 20% decrease in realised commodity prices, with all other variables held constant, of the Group\u2019s profit before tax due to changes in the realised price of reported revenues in the year. The impact on equity is the same as the impact on profit before tax.

A 20% increase in realised commodity prices would have the equal but opposite effect to the amounts shown above, on the basis that all other variables remain constant. ii) Interest risk The calculation of interest payments for the RBL facility and the optional project capital expenditure facility incorporate SOFR. The Group is, therefore, exposed to interest rate risk to the extent that SOFR may fluctuate. The Group mitigates the risk of SOFR fluctuations by entering into interest rate swaps on floating rates. There were no interest rate financial instruments in place at either 31 December 2025 or 31 December 2024. The following table summarises the sensitivity of an increase of 250 basis points in SOFR, with all other variables held constant, of the Group\u2019s profit before tax due to changes in the carrying value of monetary liabilities at the reporting date.

Since time passes between the recording of a receivable or payable transaction and its collection or payment, the Group is exposed to gains or losses on non-US Dollar amounts and on balance sheet translation of monetary accounts denominated in non-US Dollar amounts due to spot rate fluctuations from year-to-year. As at 31 December 2025, the Group had an average of \u00a325.0 million per quarter hedged at an average forward rate of $1.238:\u00a31 for the period January to December 2026. As at 31 December 2025, the Group had an average of \u00a370.1 million per quarter hedged at an average collar floor of $1.221:\u00a31 and average collar ceiling of $1.267:\u00a31 for the period January 2026 to December 2027. As at 31 December 2024, the Group had an average of \u00a321.3 million per quarter hedged at an average forward rate of $1.273:\u00a31 for the period January to December 2025. As at 31 December 2024, the Group had an average of \u00a349.5 million per quarter hedged at an average collar floor of $1.268:\u00a31 and average collar ceiling of $1.298:\u00a31 for the period January to December 2025.

Customers of the Group are mainly oil and gas majors with good credit ratings and low credit risk, including bp, Eni and Shell. The Group assesses partners\u2019 creditworthiness before entering into farm-in or joint venture agreements. In the past, the Group has not experienced credit loss in the collection of accounts receivable. As the Group\u2019s exploration, drilling and development activities expand with existing and new joint venture partners, the Group will assess and continuously update its management of associated credit risk and related procedures. The Group regularly monitors all customer receivable balances outstanding in excess of 90 days for ECLs. As at 31 December 2025, substantially all accounts receivables are current, being defined as less than 90 days. The Group has no allowance for doubtful accounts as at 31 December 2025 (31 December 2024: $nil). The Group may be exposed to certain losses in the event that counterparties to derivative financial instruments are unable to meet the terms of the contracts. The Group\u2019s exposure is limited to those counterparties holding derivative contracts with positive fair values at the reporting date and these counterparties represent a very low risk of default. As at 31 December 2025, the Group\u2019s exposure is $nil (31 December 2024: $nil). Credit valuation adjustments (CVA) and debit valuation adjustments (DVA) are calculated for each trade using two key inputs, being future exposures and credit spreads (incorporating both probability of default and loss-given default). Future exposures have been estimated using an expected exposure-based approach over the lifetime of the trades. For the risk associated with counterparties, the credit spread is calculated using market observable credit default spreads. For the own credit risk, the credit spread is calculated using reference to a senior unsecured quoted publicly traded bond of the Group using appropriate tenor adjustments, except for out-of-the-money derivatives with counterparties which are in the Group\u2019s RBL. These derivatives rank higher than those with other counterparties as they are fully secured as part of the RBL agreement. Therefore for the own risk credit risk adjustment (DVA) it has been estimated that the loss given default is zero and hence there is no DVA recognised for those derivatives which are with counterparties of the RBL. The Group also has credit risk arising from cash and cash equivalents held with banks and financial institutions. The maximum credit exposure associated with financial assets is the carrying values.

The Group manages liquidity risk by maintaining adequate cash reserves, banking facilities, and by considering medium and future requirements by continuously monitoring forecast and actual cash flows. The Group considers the maturity profiles of its financial assets and liabilities. As at 31 December 2024 and 2025, substantially all accounts payable are current. As borrowings are linked to SOFR, a spot rate at 31 December 2025 was used to calculate future borrowings cash flows.

The following tables set out the details of the Group\u2019s liquidity analysis for its derivative financial instruments based on contractual maturities. The tables have been drawn up based on the undiscounted net cash inflows and outflows on derivative instruments that settle on a net basis, and the undiscounted gross inflows and outflows on those derivatives that require gross settlement. When the amount payable or receivable is not fixed, the amount disclosed has been determined by reference to the projected interest rates as illustrated by the yield curves existing at the reporting date.

The fair value of commodity derivatives is estimated using a net present value model (commodity swaps) or an appropriate option valuation model (options and collars). These contracts are valued using observable market pricing data including volatilities. A 20% reduction in future commodity prices, with all other assumptions held constant, would result in a decrease in the fair value of derivatives of $353 million (2024: $260 million). A 20% increase in future commodity prices, with all other assumptions held constant, would result in an increase in the intrinsic value of option derivative instruments at 31 December 2025 of $124 million (2024: $113 million). Derivative financial instruments that are with counterparties included within the RBL are subject to Master Netting Agreements, this includes the majority of the Group\u2019s derivative financial instruments as at 31 December 2025 and 2024. The terms of the Master Netting Arrangements create a legally enforceable right of offset that comes into effect only on the occurrence of a specified event of default or termination event or other events not expected to happen in the normal course of business. Although the Group has the ability to net settle certain transactions with certain counterparties where an election has been made, this is not considered to be significant at either 31 December 2025 or 31 December 2024. Accordingly, the Group has not offset any derivatives balances in the statement of financial position in any of the periods presented.

Share-based payments The charge for share-based payment transactions in the year to 31 December 2025 was $7.4 million (2024: $6.1 million). Like other elements of compensation, this charge is processed through the time-writing system which allocates costs, based on time spent by individuals, to various activities within the Ithaca Energy plc Group. Part of this cost is, therefore, capitalised as directly attributable to capital projects and part is charged to the statement of profit or loss as operating costs of hydrocarbon activities, pre-licence exploration costs or administrative expenses.

All LTIP, DBS and RSU awards are nil-cost options. There are no performance conditions attaching to the Heritage, At-IPO, DBS or RSU awards. Details of the performance conditions of the 2022 LTIP, the 2024 LTIP and the 2025 LTIP are set out in the Remuneration Committee report. The fair values of all awards were determined based on the share price on date of award. The Heritage awards vested over the period to 14 November 2023, the At-IPO awards vested in three equal tranches over the period to 14 November 2025, the 2022 LTIP awards vest over the period to 1 April 2026, the 2024 LTIP awards vest over the periods to 4 July 2027 and 11 October 2027, the 2024 DBS awards vest over the period to 5 July 2027, the 2024 RSU awards vest in three equal tranches over the period to 4 July 2027, the 2025 DBS awards vest over the period to 16 April 2028 and the 2025 LTIP awards vest over the period to 31 March 2028. It is anticipated that future exercises of LTIP, DBS and RSU awards will be settled by equity. The total charge for LTIP share options, DBS awards and RSU awards in the year to 31 December 2025 was $7.4 million (2024: $6.1 million). The share-based payment reserve of $21.3 million (2024: $18.8 million) reflects the opening balance of $18.8 million (2024: $15.5 million) plus the charge of $7.4 million (2024: $6.1 million) for LTIPs, DBSs and RSUs less the cost of satisfying exercises during the year of $4.9 million (2024: $2.8 million).", "dimensions": { "concept": "ifrs-full:DisclosureOfSharebasedPaymentArrangementsExplanatory", "language": "en", "entity": "scheme:21380057TNFLXPXBIP34", "period": "2025-01-01T00:00:00/2026-01-01T00:00:00" } }, "fact-495": { "value": "34.
