For further information, please contact: Christopher.laing@fticonsulting.com Website: www.drax.com Chair's statement Andrea Bertone Chair Introduction2025 was a strong year for the Group. Operationally, we produced large volumes of flexible and renewable energyto the UK, supporting energy security, and backed up by our North American supply chain. Financially, our earnings and cash flows were strong, supporting a strong balance sheet, investment in the business and returns toshareholders. StrategyBetween 2025 and 2031, we aim to deliver c.£3 billion of free cash flow from the business which can support investment in energy security, data centres, and flexible, renewable energy in the UK, underpinning long-termvalue creation and attractive returns for shareholders. Reflecting growing UK power demand, combined with an increased reliance on intermittent and inflexiblegeneration, Drax expects to grow its FlexGen portfolio which can support energy security and the continued deployment of renewables. We see battery energy storage systems (BESS) as an important new technology forour FlexGen portfolio and are developing a gigawatt (GW)-scale pipeline of opportunities. Since October 2025,Drax has signed an agreement to acquire three BESS projects which, when fully commissioned, will providecapacity totalling 260MW, and an asset optimisation platform. We also agreed long-term tolling agreements for a further 450MW. The Group is assessing options for other renewables, which can complement its FlexGen model. The Group is also focused on options to maximise value from the Drax Power Station site. This could utilisemultiple generation technologies - including its existing biomass generation as well as flexible, renewable energy,to continue to support energy security. This could also, potentially, meet the power demands of a large-scale data centre. In November 2025, we signed a low carbon dispatchable CfD with the UK Government to cover all four biomassunits at Drax Power Station over the period April 2027 to March 2031. This was a significant milestone for theGroup and will help support UK energy security into the 2030s and deliver a net saving for consumers compared to alternative sources of dispatchable generation. People and valuesThroughout the year I continued to engage with stakeholders, including shareholders and colleagues, regulatorsand suppliers. I would like to thank all colleagues for their hard work, dedication, and expertise in helping us deliver a strong result in 2025, and their continued commitment to our purpose and the delivery of our strategy. Will Gardiner and Icontinue to enjoy meeting colleagues and attending the employee MyVoice Forums, which always provide open,rich conversations on a wide range of topics and which help to inform Board discussions. Following the signing of the low carbon dispatchable CfD, we are working to put in place the right organisation and operating models, combined with a high-performance culture which can support growth and success in the future.As a result, during 2025, the Group commenced a reorganisation process on changes to roles in certain areas ofthe business. This process will continue in 2026. Governance, compliance and sustainability Good governance, compliance and sustainability are prerequisites for a well-run company and long-term success. We recognise the importance of these matters and over the last five years we have continued to invest ingovernance and compliance functions as the footprint of the business has grown. Progress is a journey and thereare always opportunities to evolve and improve. In August 2025, the UK's Financial Conduct Authority (FCA) commenced an investigation into the Company, covering the period January 2022 to March 2024, relating to certain historical statements regarding Drax's biomasssourcing and the compliance of Drax's 2021, 2022 and 2023 Annual Reports with the Listing Rules and Disclosure

Page 6

Guidance and Transparency Rules. This process is ongoing, and we will continue to co-operate with the FCA aspart of their investigation. In December 2025, the Group was awarded an A rating by CDP for its carbon and forestry reporting. This is a year-on-year improvement and reflects the Group's continued commitment to sustainability in its widest sense.This places Drax in the top 4% of those companies that the CDP reports on globally. Board changesIn December 2024, Andy Skelton, Chief Financial Officer (CFO), announced his intention to retire from the Board and his role as CFO. Andy continued to work until August 2025 and stepped down from the Board on 1 September2025 and retired from the Group in December 2025. I would like to thank Andy for his outstanding service to theGroup over the past six years. Throughout 2025, the Nomination Committee worked on the recruitment of Andy's replacement, and on 1 September 2025 we were delighted to welcome Frank Lemmink as the new CFO. Frank has held senior financeand risk management roles over a 20-year international career with Shell plc. Frank's experience includesupstream energy with responsibility for business performance, strategies for long-term, sustainable growth and performance, and he has also worked in renewables and energy solutions, M&A, and internal audit. Frank'sexperience is invaluable as we develop our plans for the Group. In February 2026, we were pleased to appoint Mark Clare as a Non-Executive Director. Finally, Nicola Hodson stepped down from the Board in May 2025. I would like to thank Nicola for her contributionto Drax. Summary In 2025, we generated a record level of renewable generation across our portfolio of flexible and renewablegeneration assets as we continue to play an important role in the UK energy system, supporting energy security.This has resulted in a strong financial performance and returns to shareholders. At the same time, we have made good progress with our strategy, which is well aligned with our purpose and thechallenge of energy security, affordability, and decarbonisation (the energy trilemma). We are excited for the opportunities that 2026 and beyond will bring, as we seek to deliver long-term value creation for stakeholders andrealise our purpose of enabling a zero carbon, lower cost energy future. Andrea BertoneChair 25 February 2026 CEO's review Will Gardiner CEO IntroductionEnergy security, affordability, and decarbonisation remained important themes in 2025 and at Drax - which sits atthe heart of the UK energy system - we are continuing to play our part in addressing these issues. In 2025, we delivered a strong operational and financial performance, providing the reliable renewable electricity, flexibility, and system support services that the grid needs. During 2025, Drax was the sixth largest source of power, the third largest source of dispatchable power, and thesecond largest source of renewable energy in the UK. Our dispatchable 24/7 generation portfolio, backed up byour resilient North American supply chain, enables us to supply large-scale reliable renewable power to the UK. And through our flexibility, we are an enabler of more renewables on the system, supporting lower overall systemcosts and decarbonisation. In 2025, we also celebrated 60 years of operations at Cruachan Power Station and 10 years of operations for ourPellet Production business in the US South. These milestones show our continuing long-term support for energy security and the advancement of renewable energy. I would like to thank all our dedicated colleagues in thesebusinesses and across the Group for their continued professionalism and commitment. The 'Future Energy Scenarios' report, published by NESO, shows a potential doubling of electricity demand overthe next 25 years as electrification supports decarbonisation and economic growth. Our four operational power stations are helping to meet this challenge and we are developing a further three Open Cycle Gas Turbine (OCGT)and three BESS projects, with additional tolling agreements. We also see more opportunities to meet this rise in demand and, to that end, we are continuing to develop optionsfor investment in flexible, renewable energy and for the utilisation of the 4GW Drax Power Station site. The latter could utilise multiple generation technologies - including its existing biomass generation, as well as other flexible,renewable energy - to continue to support energy security. Using multiple technologies also has the potential tomeet the power demands of a large-scale data centre and, in the long term, has the potential for carbon removals from bioenergy with carbon capture and storage (BECCS), subject to the right Government policies andcommercial arrangements. The Group is also assessing options for other renewables, which can complement its FlexGen model. These opportunities are built on a firm base. Our balance sheet is strong, and the business is generatingsignificant free cash flow. We stand ready to invest in our strategy and opportunities to create value from our asset base, and will be disciplined on capital allocation, as we seek to maximise shareholder value.

SafetySafety must always be a primary focus, and, in 2025, we have not performed at the level we expect. The Total Recordable Incident Rate (TRIR) was 0.33 (2024: 0.24). The increase is partly attributable to the disposal of theOpus Energy business, where a significant number of hours were worked with a very low incident rate. We alsocontinue to track leading indicators of near miss and hazard identification rates, where performance has been much stronger, in addition to the lagging TRIR indicator, and these both represent key targets for the Group. Summary of 2025Adjusted EBITDA of £947 million, represents an 11% decrease on 2024 (£1,064 million). This reflects a strongoperational and financial performance, with a continued high level of renewable power generation and system support services, partially offsetting lower average achieved power prices. Our balance sheet is strong, with total cash and committed facilities of £942 million and Net debt of £784 million.Net debt to Adjusted EBITDA is less than 1 times - significantly below the Group's target of around 2 times. In line with our policy to pay a sustainable and growing dividend, the Group plans to pay a total dividend for 2025of 29.0 pence per share. This is an increase of over 11% on 2024 (26.0 pence per share). Since the policy's inception in 2017, the annual average rate of dividend growth has been c.11%. Throughout the year, the Group has remained focused on shareholder value. In October 2025, the Groupcompleted a £300 million share buyback programme, which had commenced in August 2024. The Groupsubsequently began a £450 million share buyback programme (first announced in July 2025), with an initial £75 million tranche. In aggregate, during 2025, the share buyback programmes have purchased c.34 million shares forc.£221 million. When combined with dividend payments this represents total returns to shareholders of c.£317million during 2025. Low carbon dispatchable CfD In November 2025, Drax signed a low carbon dispatchable CfD with the UK Government to provide c.6TWh ofbiomass generation pa between April 2027 and March 2031 - equivalent to c.30% of baseload output - with a strikeprice of £109.90/ MWh (2012 real). In addition, we have the option to produce merchant generation above the cap,and provide system support and ancillary services. The agreement includes a mechanism for Drax to request up to 500MW to power a data centre during this period. This mechanism is subject to agreement with the UK Government, taking into account factors including value formoney for consumers, energy security, and sustainability. We expect the contract to provide increased visibility on EBITDA from the asset between 2027 and 2031. We alsobelieve that Drax Power Station will continue to play a long-term role in the UK energy system through the 2030s. Flexible Generation & Energy Solutions (FlexGen) Pumped Storage and HydroAdjusted EBITDA was £111 million (2024: £138 million). During 2025, we progressed a major programme ofplanned outage works at Cruachan Power Station. This included an upgrade to the main inlet valves on all four units, in addition to a programme of works to upgrade transformers that completed in January 2026. Taking into account this planned programme of outage we believe that this represents a good underlyingperformance, and reflects continued demand for dispatchable and renewable power generation and systemsupport services. Work continues on the £80 million investment to refurbish and upgrade units 3 and 4 through to 2027. This is underpinned by a 15-year Capacity Market agreement worth over £220 million in revenue. The work is expected toadd 40MW of additional capacity by 2027 and improve unit operations. OCGTsIn the first half of 2026, we expect to take control of Hirwaun Power, the first of three new OCGTs. The second and third sites are expected to commence commissioning in 2026, which is later than originally planned, primarily dueto delays in grid connection by the relevant authorities. The OCGTs will provide combined capacity of c.900MW and be remunerated under 15-year Capacity Marketagreements, worth over £260 million in revenue. This is in addition to revenues from peak power generation and system support services. We have previously considered divestment of these assets, once commissioned, but the changing generation mixin the UK means that flexible generation assets will become more important to the energy transition. Thisincreased value informs our decision to retain these grid-balancing assets in the portfolio once commissioned. Energy Solutions Adjusted EBITDA in Energy Solutions was £49 million (2024: £51 million) comprised of £54 million from ourIndustrial and Commercial (I&C) and renewables services business (2024: £81 million) partially offset by a loss of£5 million from our Small- and Medium-sized Enterprise (SME) business (Opus) (2024: a loss of £30 million). Alongside supplying renewable energy, our I&C business is increasingly active in the provision of value-adding services. These services include asset optimisation and a route-to-market for around 2,000 embedded third-partyrenewable assets with capacity of over 800MW. In May 2025, the Group completed the sale of the remaining non-core Opus Energy SME customer meter points.We expect the sale to be supportive of the Group's target for post-2027 Adjusted EBITDA, with a leaner and more focused I&C business better able to support customers' energy needs and decarbonisation objectives. Pellet ProductionAdjusted EBITDA of £129 million was a 10% decrease on 2024 (£143 million), although production increasedincrementally and included the full-year impact of the expansion of the Aliceville pellet plant (commissioned in H12024).

The lower level of EBITDA reflects the cost-plus transfer pricing methodology used for biomass supplied fromoperations in the US South to Drax Power Station. Under this established arrangement, if the Pellet Production business reduces its cost base, its sales revenues to the UK business also reduce, resulting in lower AdjustedEBITDA. The offset to this is a lower cost of biomass for Drax Power Station, which results in higher EBITDA at theGroup level. This situation illustrates the benefit of the integrated value chain between operations in the US South and Drax Power Station, and our ongoing focus on opportunities to reduce cost. The Group's Canadian business, which primarily sells pellets into Asia under legacy contracts, is more challenged,and we continue to assess options to improve its financial performance. This contributed to the decision,announced in December 2025, to close the pellet plant in Williams Lake, British Columbia. In addition, we closed two small satellite plants in the US, with volumes consolidated into larger plants in the region. Separately, reflecting lower biomass requirements under the low carbon dispatchable CfD, the Group does notcurrently expect to invest in additional capacity - including the paused Longview project in Washington State (US) -in the short to medium term. Drax Power Station Adjusted EBITDA of £725 million was a decrease of 11% on 2024 (£814 million). This reflects a combination oflower forward contracted prices compared to 2024, partially offset by a continued high level of generation andvalue from renewable certificates. In addition, there were no major planned outages in 2025. Between October 2024 and September 2025 (the most recent period for which data is available), Drax Power Station generated over 5% of the UK's electricity and around 10% of its renewable power. During this period, itproduced, on average, 19% of the UK's renewable power at times of peak demand and on certain days over 50%. During 2025, low wind speeds led to lower proportions of wind generation and higher demand for electricity fromDrax Power Station, illustrating its ongoing importance to security of supply in the UK. The Group remains focused on opportunities to maximise value from its existing asset base. In March 2025, weentered into a 20-year joint venture agreement with Power Minerals Limited that will allow for the development of a facility adjacent to Drax Power Station. This facility which will process pulverised fuel ash into a material which canbe sold to the construction industry and used in the production of cement with a lower carbon footprint. The new facility is expected to begin operations by the end of 2026, and we believe the project could generateincremental Adjusted EBITDA of c.£5 million pa for Drax post-2027 through to 2046. There is no capital investment required by Drax. Development expenditureDevelopment expenditure of £74 million in 2025 was a reduction of 5% on 2024 (£78 million). This reflects asignificant reduction in the Elimini business, following one-off costs during its establishment in 2024 and minimal spend on BECCS, partially offset by additional OCGT commissioning costs. The current regulatory environment in the UK and US makes the risk-return profile on carbon removal projects lessattractive in the short term. Through its Elimini business, the Group continues to see carbon removals via biomassand other technologies as a cost-effective way to deliver both energy security and high integrity carbon removals at scale. Accordingly, the Group will maintain its options for long-term development in the carbon removals marketbut expects to commit limited resources for the foreseeable future. Elimini will also support the development ofnew biomass markets. Reflecting these considerations, the Group expects future development costs to increasingly focus on more short- and medium-term opportunities in FlexGen and Drax Power Station. Adjusted EBITDA and free cash flow targets from the existing businessThe Group continues to target post-2027 Adjusted EBITDA of £600-700 million pa before developmentexpenditure. Reflecting growing UK power demand, combined with an increased system reliance on intermittent and inflexible generation, Drax expects to grow its FlexGen portfolio to comprise a greater proportion of total Adjusted EBITDAover time. Drax is targeting free cash flow of c.£3 billion (2025-2031), based on strong cash flows from the current business(2025-2026), together with targeted Adjusted EBITDA (2027-2031), plus working capital, less maintenance capital expenditure, interest and tax. The Group's capital allocation policy is unchanged. Drax expects to initially allocate more than £1 billion of freecash flow to shareholder returns (2025-2031). This is inclusive of the ongoing £450 million three-year sharebuyback programme, and the continuation of its long-standing policy to pay a sustainable and growing dividend. Drax expects to allocate up to c.£2 billion to incremental investment, primarily in the flexible and renewable energy the UK needs, as well as opportunities to maximise value from the Drax Power Station site. Returns to shareholders and investment for growth follow a capital ranking process which aims to maximise riskadjusted returns to shareholders. Putting in place the structures to allow the Group to succeed and growDelivery of the Group's targets and strategy is underpinned by disciplined cost management and an operating model adapted to reflect the structure of the new low carbon dispatchable CfD, combined with a high-performanceculture. Options to invest in growth - FlexGen - flexible and renewable energyThe continued decarbonisation of the UK power system and new sources of demand, are leading to a greaterreliance on intermittent renewables. The system is becoming cleaner but more volatile, driving a growing need for dispatchable power and system support services. This creates long-term earnings opportunities for, and value

from, the Group's FlexGen assets. While the trend is clear, it is hard to forecast from year-to-year, beingdependent on weather and associated renewable activity as much as underlying commodity prices. This position informs the Group's view on the value of its FlexGen portfolio and opportunities for growth, which can support energy security and the continued deployment of renewables. Since acquiring the pumped storage andhydro assets in 2018, utilisation of these assets has increased significantly, delivering a five-year payback oninvestment. In addition to its existing operational assets and developments, the Group sees BESS as an important new technology for its FlexGen portfolio. Adding fast response capabilities to existing long-duration pumped storageand OCGT assets, BESS could allow the portfolio to provide a wider range of system support services to the grid. Drax is developing a GW-scale pipeline of BESS opportunities. These comprise both physical assets and thecapabilities to optimise third-party assets by providing route-to-market, floor, and tolling structures. These can complement its existing route-to-market offering for renewable assets in Energy Solutions. In October 2025, Drax signed an agreement with Apatura to acquire three BESS projects for £157.2 million which,when fully commissioned, will provide capacity totalling 260MW. In January 2026, Drax announced the acquisitionof Flexitricity for £36 million, providing an optimisation platform for the development of the Group's FlexGen portfolio, including BESS. Also in January 2026, Drax agreed a 10-year tolling agreement with Fidra, which givesthe Group operational control and dispatch rights over 250MW of new BESS capacity from 2028, and a 15-yeartolling agreement with Zenobē, which gives the Group operational control and dispatch rights over 200MW of new BESS capacity from 2028. The Group is also assessing options for other renewables projects to complement its FlexGen model. Options to invest in growth - Drax Power Station siteThe Drax Power Station site comprises over 1,000 acres and 4GW of capacity and grid access, with 2.6GW ofactive dispatchable generation, cooling systems, and proximity to the UK fibre network. The Group is actively evaluating options to utilise inactive legacy units to provide system support services. Forexample, by using power from the system to spin these inactive turbines we can synchronise them to the system and use their physical mass to provide inertia, thereby helping to stabilise the system. Drax is also considering a range of options for the site which could utilise its existing land, grid access, activegeneration, cooling solutions, site security, location, and skilled workforce to meet the needs of data centredevelopers. Drax is preparing a planning application to support the potential option for a first phase data centre of c.100MW on land identified at Drax Power Station. This could use the existing infrastructure and transformers previously usedto support coal generation to import power directly from the grid (front-of-the-meter). This could support theoperation of a data centre at Drax Power Station as soon as 2027, subject to the necessary consents and agreements. In the long term, Drax is developing options for over 1GW of data centre capacity. This could utilise existinggeneration capabilities at Drax Power Station to provide a distributed (behind-the-meter) energy solution witharound-the-clock renewable power directly to a data centre under a long-term Power Purchase Agreement, subject to necessary consents and agreements. Any decision to develop data centres at Drax Power Station will require a full assessment of the capital cost andinvestment case, as well as establishing the commercial and development structures. Pellet ProductionAs a part of the Group's post-2027 targets, the low carbon dispatchable CfD at Drax Power Station is expected to utilise c.2Mt of own-use pellets from the US South (in addition to third-party volumes). This, together with existingsales to third parties, primarily in Asia, provides a good underpin to the current level of value generated for theGroup from Pellet Production. Long-term development of biomass and carbon markets In the long term, Drax remains positive on the role of biomass in industrial decarbonisation and carbon removalsvia its Elimini business. Drax continues to assess options for own-use and third-party sales, from existing and newmarkets, including Sustainable Aviation Fuel (SAF), which could represent a new market opportunity through the 2030s. SustainabilityIn addition to delivering a strong operational and financial performance and value for shareholders, the Group hasremained focused on the development of its sustainability programme. In 2025, we launched a new Sustainability Framework, Biomass Sourcing Policy, and a Climate Transition Plan. As a purpose-led organisation, our growth should lead to positive outcomes for climate, nature, and people. Ouroperations can help sustain more healthy, safe, and economically viable working forests that continue to providejobs and opportunities in communities where we operate. Working in partnership with industry, communities, scientists, and civil society organisations will be vital to achieving our ambitions. We aim to work openly and constructively with these groups to help deliverimprovements. We are fully aligned with the Task Force on Climate-related Financial Disclosures (TCFD). We are also an early-adopter of the Taskforce on Nature-related Financial Disclosures (TNFD). In addition, we are members of the Taskforce on Inequality and Social-related Financial Disclosures (TISFD) Alliance. These independent taskforcesalign directly with the three pillars of our new Sustainability Framework; Climate, Nature, and People. We are alsoa signatory to the UN Global Compact (UNGC) and we are committed to promoting the UNGC principlesconcerning respect for human rights, labour rights, the environment, and anti-corruption.

Drax is one of the world's largest users of sustainable biomass for energy generation. We are committed toensuring the woody biomass we source comes from forests managed in accordance with standards designed to support their health and growth over the long term. Forests in the areas where Drax sources material are subjectto national and regional regulation and are typically supported, and independently monitored for compliance, byforest certification schemes. These include the Forestry Stewardship Council® (FSC®) (FSC C123692), the Sustainable Forestry Initiative (SFI) (SFI marks are registered marks owned by the Sustainable Forestry InitiativeInc.), and the Programme for the Endorsement of Forest Certification® (PEFC) (PEFC/29-31-286). We supplement this regulation through our own Biomass Sourcing Policy and supply chain checks. This includesthird-party verification under the Sustainable Biomass Program (SBP), in respect of woody biomass used at Drax Power Station, which is also fully compliant with the UK Government's rule on the use of sustainable biomass. OutlookWe are continuing to target post-2027 Adjusted EBITDA of £600-700 million pa from our FlexGen, PelletProduction, and Biomass Generation businesses, maximising value from the business today, while continuing to identify opportunities for growth across our strategies for flexible, renewable energy. We will continue to apply our capital allocation policy with a focus on balance sheet strength, investment in thecore business, and a sustainable and growing dividend. To the extent there are residual cash flows beyond thecurrent needs of the Group, we will also consider additional returns to shareholders. Through a disciplined approach to capital allocation and development costs, we expect to create opportunities for investment in growth and value creation, underpinned by strong cash generation and attractive returns forshareholders. Will GardinerCEO 25 February 2026 CFO's financial review Frank Lemmink CFO Year end 31 December 2025 2024 Financial performance (£m) Total gross profit 1,513 1,877 Operating expenses (641) (761) Depreciation, amortisation and impairment of non-currentassets (621) (256) Other (10) (10) Total operating profit 241 850 Exceptional items and certain remeasurements 430 (50) Adjusted operating profit 671 800 Adjusted depreciation, amortisation and similar charges andshare of losses from associates 275 264 Adjusted EBITDA 947 1,064 Capital expenditure (£m) Capital expenditure 202 321 Cash and Net debt (£m unlessotherwise stated) Cash generated from operations 1,000 1,135 Net debt 784 992 Net debt to Adjusted EBITDA (times) 0.8 0.9 Cash and committed facilities 942 806 Earnings (pence per share) Adjusted basic 137.7 128.4 Total basic 20.7 137.5 Distributions (pence per share)Interim dividend 11.6 10.4 Proposed final dividend 17.4 15.6 Total dividend 29.0 26.0 Throughout this document we distinguish between Adjusted measures and Total measures, which are calculated in accordance withInternational Financial Reporting Standards (IFRS). We calculate Adjusted financial performance measures, which exclude income statementvolatility from derivative financial instruments and the impact of exceptional items. This allows management and stakeholders to better compare the performance of the Group between the current and previous period without the effects of this volatility and one-off or non-operational items.Adjusted financial performance measures are described in more detail in the APMs glossary, with a reconciliation to their closest IFRSequivalents in note 4. Return on Capital Employed (ROCE) is calculated as Adjusted operating profit divided by the average of opening andclosing capital employed (capital employed is gross assets less current liabilities). Tables in this financial review may not add down or across due to rounding. IntroductionAdjusted EBITDA of £947 million represents strong operational and underlying financial performance across allsegments of our business. The decrease compared to £1,064 million in 2024 primarily reflects a lower achieved power price. Total operating profit was impacted by impairments, as discussed in the 'Total operating profit' section.During the period, we generated cash from operations of £1,000 million (2024: £1,135 million). Our Net debt:Adjusted EBITDA ratio of 0.8 times (2024: 0.9 times) remains significantly below our long-term target of around 2

Page 11

times and during the year we further strengthened our balance sheet, extending the average maturity of our debtand extending the Revolving Credit Facility (RCF) by a year to 2028. Financial performance Adjusted EBITDA by businessFlexible Generation & Energy Solutions (FlexGen)Adjusted EBITDA in our Hydro business of £111 million reduced compared to 2024 (£138 million), reflecting planned outage work at Cruachan Power Station as part of refurbishment and upgrade works. Adjusted EBITDA in Energy Solutions of £49 million (2024: £51 million) comprised £54 million from our I&C andrenewables services business (2024: £81 million) partially offset by a loss of £5 million from our Small andMedium-sized Enterprise (SME) business (Opus) (2024: a loss of £30 million). I&C and renewables services earnings reflect a similar margin on contracted power prices to 2024. The sale of the remaining meter points in theSME business completed in May 2025. The wind down of this business is now substantially complete. Pellet ProductionAdjusted EBITDA of £129 million was below 2024 (£143 million). The reduction reflects the cost-plus transfer pricing methodology for shipments to Drax Power Station. This means that cost savings in the Pellet Productionbusiness lead to a lower transfer price, impacting Adjusted EBITDA. Production in the period totalled 4.2Mt, arecord volume for the business (2024: 4.0Mt). Shipments totalled 5.1Mt (2024: 5.1Mt). Of the 5.1Mt shipped, 3.1Mt was to Drax Power Station (2024: 3.0Mt). During the period, 1.0Mt of pellets were acquired from third parties(2024: 1.1Mt). The US business has performed well, with record production volumes and margins commensurate with our long-term targets. The legacy contracts in the Canadian business mean profitability here is lower, and this is an area of focus for the Group, as discussed in the CEO review. Impairments in relation to the Pellet Production business are documented in the 'Total operating profit' section. Biomass Generation Adjusted EBITDA from Biomass Generation was £725 million (2024: £814 million), partially offset by a continuedhigh level of generation and value from renewable certificates. In addition, there were no major planned outagesin 2025. Drax Power Station produced 15.0TWh (2024: 14.6TWh) of electricity, a record year for biomass generation and making it the UK's largest single source of renewable energy during the period. Options for Growth (Innovation, Capital Projects, and Other)Development expenditure in 2025 totalled £74 million (2024: £78 million). The reduction reflects the timing of largecapital projects, as described in the CEO review, and therefore a reduction in the associated spend. We will continue to be disciplined in the capital and development expenditure deployed to these projects. In Other, intra-group eliminations moved to a credit of £7 million in 2025 from a charge of £3 million in 2024,predominantly due to a reduction in the volume of pellets in transit compared to the previous year end. Total operating profitTotal operating profit was £241 million, compared to £850 million in 2024. In addition to the factors discussed above, Exceptional items and certain remeasurements also reduced, from a credit of £50 million in 2024 to acharge of £430 million in 2025. This was attributable to impairments, gas prices, and foreign exchangemovements. Impairments were recognised for certain pellet assets and UK BECCS, whilst continuing depreciation and amortisation was similar year-on-year. In Pellet Production, impairment and related charges in Northern Pellets (Canadian business) were £198 million.Charges in relation to the Longview project were £138 million and UK BECCS impairments were £48 million. All ofthese were classed as exceptional items. The impairment to Northern Pellets was driven by a lower growth outlook for the global pellet market after 2027, particularly in Europe. Linked to this, the development project at Longviewwas paused and no development is expected in the near term. Whilst UK BECCS is still an attractive option for theGroup in the long term, the current political environment and absence of an appropriate regulatory framework has led to a reduction in the likelihood of the project proceeding in the short- to medium-term. Accordingly, thecapitalised value has been impaired. Further information on other Exceptional items and certain remeasurements can be found in note 4. Profit after tax and Earnings per shareTotal net finance and foreign exchange costs for 2025 were £52 million, a reduction from 2024 (£97 million). Of the reduction, £24 million was attributable to capitalisation of interest, £15 million in foreign exchange, and £7 millionas a result of lower costs in relation to the Energy Solutions receivables monetisation facility. This was partiallyoffset by a £2 million reduction in interest received. At 31 December 2025, the weighted average interest rate payable on the Group's borrowings was 5.4% (31 December 2024: 5.4%). The Adjusted effective tax rate for 2025 of 22% is lower than 2024 (30%), with a key factor being a £nil charge forEGL in the current year (2024: £161 million) reflecting lower achieved power prices. EGL is not allowable forcorporation tax purposes and the corporation tax impact of this reduction in EGL was 6%. The Adjusted effective tax rate is below the headline corporation tax rate in the UK of 25% because of benefits from the UK Patent BoxRegime, partially offset by non-deductible expenses. The exceptional items and certain remeasurements tax creditof £16 million all related to deferred tax and was the net of deferred tax on all non-Canadian exceptional items and certain remeasurements partially offset by the non-allowable Canadian impairment charge and derecognition ofCanadian deferred tax assets. Adjusted basic EPS was 137.7 pence (2024: 128.4 pence) and Total basic EPS was 20.7 pence (2024: 137.5pence). The average number of shares used in these calculations was 352.8 million (2024: 383.2 million). The number of outstanding shares at 31 December 2025 was 340.4 million, an 8% reduction on 31 December 2024(369.9 million), reflecting the ongoing share buyback programme.

Capital allocationOur capital allocation policy remains unchanged and focused on balance sheet strength, investment in the core business, a sustainable and growing dividend and, to the extent there are residual cash flows beyond the currentneeds of the Group, additional returns to shareholders. Maintain credit ratingDuring the first half of 2025 the Group extended the maturity of the undrawn £450 million RCF and in July two term loans totalling c.£171 million were extended from 2027 to 2028. During December the Group signed a £190 millionterm loan with an interest rate of Sterling Overnight Index Average (SONIA) plus a customary margin. The facilityhas an option at Drax's discretion to extend by two six-month periods. The facility was undrawn at 31 December 2025 but was subsequently fully drawn in January 2026. In August 2025 the CAD term-loan of £109 million was repaid. In October 2025 the remaining £125 million of the2025 Euro bond was repaid. In January 2026, term loans totalling £62 million were repaid. During the second quarter of 2025, the Group's Issuer Credit Ratings were reaffirmed as 'BB+' by Fitch and S&Pand as 'BBB (low)' by DBRS, with a Stable Outlook in each case. Invest in core business - capital expenditure Capital expenditure of £202 million (2024: £321 million) consists of £98 million of growth expenditure, £72 millionof maintenance, and £32 million of Other (including HSE and IT). Of the £98 million growth expenditure, £26million related to BESS assets (2024: £nil) and £23 million related to the OCGTs (2024: £90 million). The first of the three OCGTs, Hirwaun, is expected to be under the Group's commercial control shortly and the other two unitsare expected to commence commissioning during 2026. Growth expenditure also included £15 million in relation tothe ongoing upgrade of Cruachan units 3 and 4 (2024: £34 million). In October 2025 we announced we had signed an agreement with Apatura to acquire three BESS projects for £157.2 million. Completion of the acquisition of the first two projects occurred in 2025 and completion of the thirdproject is expected soon. Sustainable and growing dividendThe Board expects to pay a dividend for the 2025 financial year of 29.0 pence per ordinary share, an 11.5%increase on 2024, consistent with our policy to pay a dividend which is sustainable and expected to grow. As has been our practice, 40% of the expected full year dividend, or 11.6 pence per ordinary share was paid as an interimdividend. Subject to approval at the 2026 Annual General Meeting, the final dividend will be paid on 15 May 2026. Return surplus capital beyond current investment requirementsIn October 2025, the Group completed a £300 million share buyback programme which had commenced in August 2024. The Group subsequently began a £450 million share buyback programme (first announced in July 2025),with an initial £75 million tranche. In aggregate, during 2025, the share buyback programmes have purchased c.34million shares for c.£221 million. When combined with dividend payments this represents total returns to shareholders of c.£317 million during 2025. During 2026, to 24 February 2026, the Group has repurchased £22 million. We expect the 2025 programme toconclude by the end of 2028. Cash and Net debtNet cash movements Cash generated from operations, inclusive of working capital, was £1,000 million (2024: £1,135 million). The networking capital inflow of £86 million (2024: £122 million) predominantly reflects a reduction in inventory andreceivables, partially offset by a decrease in payables. Cash outflows on purchases of property, plant and equipment and intangibles include repayments of deferred letters of credit from previous periods. This led to a cash outflow of £294 million, more than the amount capitalisedin the period of £202 million. LiquidityCash and committed facilities of £942 million at 31 December 2025 (31 December 2024: £806 million) provided substantial headroom over our short-term liquidity requirements.

The Group refreshes its business plan and forecasts throughout the year, including scenario modelling designed totest the resilience of the Group's financial position and performance to several possible downside cases. Based on its review of the latest forecast, the Board is satisfied that the Group has sufficient headroom in its cash andcommitted facilities and covenants, combined with available mitigating actions, to be able to meet its liabilities asthey fall due across a range of scenarios. Consequently, the Directors have a reasonable expectation that the Group will continue to be in existence for a period of at least twelve months from the date of the approval of the financial statements and have thereforeadopted the going concern basis. Further, the Directors have a reasonable expectation that the Group will be ableto continue in operation over the five-year period of the viability assessment, as documented in the Viability Statement. Other mattersIn January 2026, the Group announced the acquisition of Flexitricity, an asset optimisation platform, for c.£36million. Completion is expected in Q1 2026 and is conditional on completion of regulatory approvals and processes. In January 2026, the Group announced a 10-year tolling agreement with Fidra for 250MW (500MWh) of BESS,expected to commence in 2028. In February 2026, the Group announced a 15-year tolling agreement with Zenobē for 200MW (800MWh) of BESS,expected to commence in 2028.

Further details of the cash flow impact of exceptional items can be foundin note 4. 1. Segmental reportingReportable segments are presented in a manner consistent with internal reporting provided to the chief operating decision maker which is considered to be the Executive Committee. The Group is organised into four businesses.The Executive Committee reviews the performance of each of these businesses separately, and each represents areportable segment: - Pellet Production: production and subsequent sale of biomass pellets from the Group's processing facilities in North America- Biomass Generation: generation and sale of electricity from the Group's biomass assets in the UK - Flexible Generation: generation and sale of electricity from pumped storage, run-of-river hydro and OCGT assets, and the processing and sale of waste-derived pellets, in the UK- Energy Solutions: supply of electricity to non-domestic customers in the UK Operating costs that can be reasonably allocated to the activities of a reportable segment are included within theresults of that reportable segment. Central corporate and commercial functions provide certain specialist and shared services, including optimisation of the Group's positions. Central corporate and commercial function coststhat cannot be reasonably allocated to the activities of a reportable segment are included within Innovation, capitalprojects and other. Innovation, capital projects and other is not a reportable segment as it provides central support function activities to the Group, however it is included in the information presented below to enable reconciliationof the segmental amounts presented to the consolidated IFRS results recognised in these Consolidated financialstatements. Given the principal activity of the Group is a generator and seller of electricity, the Consolidated income statement includes all revenue from sales of electricity during the period. Where the Group is acting as the principal in asales transaction and electricity is purchased rather than generated to fulfil that sale, either due to operational orother requirements, the cost of this purchase is recorded within cost of sales. When defining gross profit within the Consolidated financial statements, the Group follows the principal trading considerations applied by its Pellet Production, Biomass Generation, Flexible Generation and Energy Solutionsbusinesses when making a sale. In respect of the Pellet Production business, this reflects the direct costs ofproduction, being fibre, fuel and drying costs, direct freight and port costs, or third-party pellet purchases. In respect of the Biomass Generation and Flexible Generation businesses, this reflects the direct costs of thecommodities required to generate power or the direct cost of purchasing power, the relevant grid connection coststhat arise, and the Electricity Generator Levy (EGL) arising on applicable renewable and low-carbon generation. In respect of the Energy Solutions business, this reflects the direct costs of supply, being the costs of the power orgas supplied, together with costs levied on suppliers such as network costs, broker costs and renewablesincentive mechanisms. Accordingly, cost of sales excludes indirect overheads and staff costs (presented within operating and administrative expenses), and depreciation (presented separately on the face of the Consolidated incomestatement). The accounting policies applied for the purpose of measuring the reportable segments' profits or losses, assetsand liabilities are the same as those used in measuring the corresponding amounts in the Consolidated financialstatements. EGL applies to the Group's three biomass units operating under the Renewables Obligation (RO) scheme and its run-of-river hydro operations. It does not apply to the Group's Contract for Difference (CfD) biomass unit or itspumped storage hydro operations. The EGL applies at a rate of 45% to receipts from in-scope forms of wholesaleelectricity generation that exceed a defined benchmark level, after the deduction of certain allowable costs, from 1 January 2023 to 31 March 2028. The Group determined that EGL should be treated as a levy under IFRIC 21 'Levies', rather than as a tax underIAS 12 'Income taxes'. Therefore, the cost is recognised above gross profit. A liability for a levy is recognised oncethe obligating event, being the activity that triggers the payment of the levy, has occurred. EGL is triggered based on average generation receipts for in-scope revenue schemes over a reporting period being higher than thethreshold set in the legislation. A liability is recognised if the average actual generation receipts to date in afinancial period are above the threshold. The threshold rises annually in April, in line with the UK Consumer Price Index (CPI). The threshold at 31 December 2025 was £79.95 per MWh (2024: £77.94 per MWh). The assessmentis based on receipts above this threshold after adjusting for allowable costs. No expense for EGL has beenrecognised in the current period due to the average actual generation receipts in the period being below the threshold. Seasonality of tradingThe primary activities of the Group are affected by seasonality. Demand in the UK for electricity is typically higherin the winter period (October to March) when temperatures are lower, which drives higher prices and higher levels of generation. Conversely, demand is typically lower in the summer months (April to September) whentemperatures are milder, and therefore prices and levels of generation are generally lower. This trend is experienced by all of the Group's UK-based businesses, as they operate within the UK electricitymarket. It is most notable within the Biomass Generation business due to its scale and the flexible operation of its

Page 19

thermal generation plant. The Pellet Production business incurs certain costs that are higher in winter months due to the impact of weatherconditions, such as fibre drying costs and heating costs. Production volumes and margins are typically higher in the summer months. The business is protected from demand fluctuations due to seasonality by regular productionand dispatch schedules under its contracts with customers, both intra-group and externally. Segment revenues and resultsThe following is an analysis of the Group's performance by reportable segment and any other information necessary to enable reconciliation to the Group's total IFRS results recognised for the year ended 31 December2025. Revenue for each segment is split between sales to external parties and inter-segment sales. Inter-segmentsales are eliminated in the intra-group eliminations column along with any adjustments required for unrealised profits (primarily inventory purchased by the Biomass Generation segment from the Pellet Production segment thatis still held as inventory at the reporting date). Adjusted EBITDA by reportable segment is presented in note 4.

Capitalised interest and plant spares are now excluded from the definition of capital expenditure. In the year ended31 December 2024 there was £1.7 million of capitalised interest (Pellet Production £0.1 million and Flexible Generation £1.6 million) and £9.9 million of capitalised plant spares (Pellet Production £4.5 million, Biomass Generation £4.6 million and Flexible Generation £0.8million) that were included in the amounts presented in the 2024 Consolidated financial statements. Comparative amounts in the tableabove have been restated to exclude capitalised interest and capitalised plant spares. Total cash outflows in relation to capital expenditure during the year were £294.2 million (2024: £387.5 million). Inthe current year, the cash outflow in relation to property, plant and equipment is higher than the cost capitalised, predominantly as a result of a decrease in creditors relating to capital expenditure within the year. Intra-group tradingIntra-group transactions are carried out at management's best estimate of arm's-length, commercial terms that,where possible, equate to market prices. The impact of all intra-group transactions, including any unrealised profit arising, is eliminated on consolidation.

RevenueAccounting policy Revenue represents amounts receivable for goods or services provided to customers in the normal course ofbusiness, net of trade discounts, VAT and other sales-related taxes and excludes transactions between Groupcompanies. Revenue is presented gross in the Consolidated income statement when the Group controls the specified good or service prior to the transfer to the customer. When the Group is acting primarily as an agent,revenue is recognised on a net basis. A summary of the Group's principal revenue streams, along with the nature and timing of performance obligations,payment terms, methods of recognising revenue, and any estimation uncertainties, is given in the table below. The majority of the Group's revenue is within the scope of IFRS 15. The other sources of the Group's revenue outside the scope of IFRS 15 comprise gains and losses on certain non-hedge accounted derivatives, theineffective portion of certain hedge accounted derivatives, amounts reclassified to revenue for gains and losses onhedge accounted UK inflation swaps, Contract for Difference (CfD) income, and income from the UK Government's Energy Bills Discount Scheme (EBDS). See note 4 for further details on gains and losses onderivatives. Gains and losses recognised in the Consolidated income statement on derivative contracts that areentered to hedge a revenue item are presented within the same revenue stream line as the revenue item they are intending to hedge.

Customers generallyobtain control of the pellets at the point thepellets are loaded onto the shipping vessel. Where freight is also arranged for thecustomer, these sales are known as cost, insurance and freight (CIF) sales. The freightcomponent is considered a separateperformance obligation. Invoices are raised in line with contractualterms and are usually payable within 4-10 days. Revenue is recognised at the point thatthe pellets are loaded onto the shipping vessel. The amount of revenue recognised isbased on the contracted price and volume ofthe pellets. For CIF sales, revenue for the freight portionis recognised over the period the vessel sails. Electricity sales(Biomass Generation andFlexible Generation) The Group's Biomass Generation and FlexibleGeneration businesses have contracts for wholesale electricity sales. Performanceobligations, being the supply of electricity, aremet either via generation or through the procurement of electricity from counterparties.The performance obligations for thesecontracts are deemed to be a series of distinct goods that are substantially the sameand transfer consecutively. Control is deemedto have transferred to the customer at the point that the electricity has been supplied inaccordance with the contractual terms. Invoices for electricity are typically raised onthe fifth banking day following the month ofsupply, in line with the Grid Trade MasterAgreement (GTMA) contractual terms, and are payable on the fifth banking day following thedate of invoice. Revenues from sales contracts fulfilledthrough generation are recognised at a point in time based upon metered output at ratesspecified under contractual terms. Revenue from sales contracts fulfilledthrough procured electricity is recognised atthe point at which this electricity or gas is supplied to the counterparty in accordancewith the contractual terms at rates specifiedunder the contract. These are recognised under the outputmethod, whereby revenue is recognised based on the value transferred to thecustomer. Renewable certificate sales(BiomassGeneration, Flexible Generation andEnergy Solutions) Renewables Obligation Certificates (ROCs) and Renewable Energy Guarantees of Origin(REGOs) are sold to counterparties at a pointin time. ROCs sold are invoiced in line with contractualterms and are usually payable within two to five days. Invoices for REGOs are raised in line with contractual terms and are usually payablewithin 7-30 days. External ROC and REGO sales are recognised at the point the relevantrenewable certificates are transferred to thecounterparty. CfD income (BiomassGeneration) The Group's Biomass Generation business is party to a CfD with the Low Carbon ContractsCompany (LCCC), a UK Government-ownedentity responsible for delivering elements of the UK Government's Electricity MarketReform programme. Under the contract, theGroup receives income in respect of electricity dispatched from a specific biomass-fuelledgenerating unit. Invoices are raised 7-10 days following thedate of supply and are settled within 28 days. The Group recognises the income arising from the CfD in the Consolidated incomestatement as a component of revenue at thepoint the Group meets its performance obligation under the CfD agreement. This isconsidered to be the point at which therelevant generation is delivered. See CfD income section below for furtherdetails. Ancillary services(Biomass Generationand FlexibleGeneration) Ancillary services refer to the provision of arange of system support services to National Grid. Most contracts are for the delivery of aspecific service either continually or on an ad-hoc basis over a period of time. Invoices are raised and subsequently settled inline with the National Grid company ancillary services settlement calendar, typically monthly. Revenue is recognised over time for ancillaryservices as the Group provides the service of either being available and ready to supportthe UK Electricity Grid or providing a servicewhen called upon to support the UK Electricity Grid.

Revenue stream(Segment) Nature and timing of performance obligations,including significant payment terms Method of recognising revenue, including anyestimation uncertainties obligations are calculated by reference tothe amount of the contract term that has elapsed. Revenue recognised for providing services when called upon are recognised over thetime the service is being provided to supportthe UK Electricity Grid. Depending on contract terms, this approachmay require judgement in estimating probable future outcomes when the amountof consideration the Group is entitled to isvariable based on its performance over a period of time. Electricity and gassales (Energy Solutions) The Group's Energy Solutions business sellselectricity and gas directly to non-domestic customers. Energy supplied is measuredbased upon metered consumption andcontractual rates. The Energy Solutions business also has long-term contracts for the sale of electricity and gas, which are a series of distinct goods orservices that are substantially the same andhave the same pattern of transfer and are a performance obligation that is deemed asbeing satisfied over time in line withthe progress of the contracts. Invoices are raised in line with contractualterms which for most customers is monthly. Payment is generally due between 28-90 days. Revenue is recognised on the supply ofelectricity or gas when a contract exists, supply has taken place, a quantifiable pricehas been established or can be determined,and the amounts receivable are expected to be recovered. Where supply has taken place but has not yet been measured or billed, revenueis estimated based on consumption statisticsand selling price estimates and is recognised as accrued income. This estimate is notconsidered to be a key source of estimationuncertainty because historical experience has demonstrated that these estimates arematerially accurate based on the subsequentbillings and settlements. Where contracts for the sale of electricity andgas are held, revenue is recognised in line with the progress of the contracts. Revenue recognised for fixed price contractsis based on the input method. Revenue is recognised based on the costs incurred andthe estimated margin to be obtained over thelife of the contract. For variable price contracts revenue is recognised based onthe output method. Revenue is recognisedbased on the volume supplied and the contracted price. Assumptions are appliedconsistently but third-party costs can vary,therefore actual outcomes may vary from initial estimates. EBDS income(Energy Solutions) The UK Government introduced the EBDSrunning from 1 April 2023 to 31 March 2024. Under this scheme, energy supplied to eligiblenon-domestic customers had a discountapplied to each unit of electricity and gas. Certain customers were eligible for higherlevels of support dependent on the sector inwhich they operated. The discount provided was then able to be claimed back from theUK Government by the supplier. Payment was due 10 days post submission ofa claim, which typically occurred monthly. The discounted price of electricity and gassupplied under EBDS was recognised in revenue as it was supplied. The amountclaimed back from the UK Governmentwas recognised within revenue over the same period as the underlying discountedrevenue it related to was recognised. The revenue received from the UKGovernment is included in the EBDS incomeline in the table below. The Group did not recognise any additional revenue from thescheme than it would have done had it notbeen introduced. Other income(All segments) Other income is derived from the sale ofgoods. The customer obtains control typicallyat the point of delivery to their premises or upon collection. Invoices are raised in line with contractual terms. The majority of invoices are raisedquarterly and are payable within 30 days. Revenue is recognised at the point thecontrol of the goods is transferred to thecustomer. Renewable certificate salesThe generation and sale of renewable certificates, primarily ROCs and REGOs, is a key driver of the Group's financial performance.

Page 24

During the year, the Group made sales and related purchases of ROCs to help optimise its working capitalposition. External sales of ROCs in the table below includes £237.5 million of such sales (2024: £50.8 million), with a similar value reflected in cost of sales. The renewable certificate sales revenue in the Biomass Generationbusiness of £931.0 million has increased compared to the prior year (2024: £739.3 million) primarily as a result ofthe increase in these ROC sales. CfD income The income is calculated by reference to a strike price per MWh. The base year for the strike price was 2012 and itincreases each year in line with the UK Consumer Price Index (CPI) and changes in system balancing costs. Thestrike price at 31 December 2025 was £142.24 per MWh (2024: £138.16 per MWh). When market prices (based on average traded prices in the preceding season) are above or below the strike price, the Group makes an additional payment to or receives additional income from LCCC equivalent to the differencebetween that market power price and the strike price, for each MWh produced from the relevant generating unit.Such payments or receipts are in addition to amounts received from the sale of the associated power in the wholesale market.

See note 4 forfurther details on certain remeasurements included within revenue. Revenue recognised in the period that was included within contract liabilities at the start of the year was £23.1million (2024: £16.8 million). Revenue recognised in the period from performance obligations satisfied or partly satisfied in the previous period was £nil (2024: £nil).

The Group's Biomass Generation and Flexible Generation segments have contracts for wholesale electricity sales.Performance obligations, being the supply of electricity, are met either via electricity generation or through the procurement of electricity from counterparties. Where electricity is procured from counterparties to meet thisobligation, the electricity sale is presented on a gross basis with the cost of buying the electricity presented in costof sales and the sale of this electricity presented in revenue. If external purchases of power were presented net within external revenue this would have reduced external revenue by £1,044.8 million to £4,345.9 million(2024: by £1,072.9 million to £5,089.6 million) with a corresponding decrease in external cost of sales. For most customer contracts the Group is eligible for, and applies, the practical expedient available under IFRS 15and has not disclosed information related to the transaction price allocated to remaining performance obligations. This applies to revenue where either the right to receive consideration from the customers is at an amount thatcorresponds directly with the value transferred to the customer for the Group's performance completed to date, orthe contract's original expected duration is less than one year. For the Group's fixed price energy supply contracts that have an original expected duration of more than one year, the aggregate amount of the transaction priceallocated to performance obligations that are unsatisfied at the end of the reporting period is shown in the tablebelow.

Impairment review of non-current assets Accounting policyGoodwill is tested for impairment at least annually. For the purpose of impairment testing, goodwill is allocated toeach of the Group's cash-generating units (CGUs) or group of CGUs expected to benefit from the synergies of the business combination. A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of thecash inflows from other assets or groups of assets. CGUs are identified consistently from period to period unlessthere is a change in the period that would impact the Group's CGUs. The Group's CGUs are reassessed should any such changes occur. The Group reviews its non-current assets (and, where appropriate, groups of assets combined into a CGU)whenever there is an indication that an impairment loss may have been suffered. The Group assesses theexistence of indicators of impairment at the end of each reporting period. If an indication of potential impairment exists, the recoverable amount of the asset or CGU in question is assessed with reference to the present value of the future cash flows expected to be derived from the continuing use of theasset or CGU (value in use), or the expected price that would be received if the asset or CGU were sold to amarket participant (fair value less costs of disposal). The recoverable amount of an asset or CGU is the higher of its fair value less costs of disposal (FVLCD) and its value in use (ViU). The initial assessment of the recoverableamount is normally based on ViU unless FVLCD is considered more appropriate. The future cash flows used in ViU calculations are based on the approved long-term forecasts that support theBoard and executive management's strategic planning process and include all expected costs necessary togenerate the cash inflows from the CGU's assets in their current state and condition, including an allocation of centrally managed costs. Future cash flows include, where relevant, contracted cash flows arising from theGroup's forward hedging activities and as a result the carrying amount of each CGU includes the fair value ofthose hedges. Assessments of future cash flows consider relevant environmental and climate change factors. In particular, macro-economic, commodity price and third-party cost assumptions reflect considerations in respect of the impactof climate change, growth in renewable technologies, electrification and the impact of relevant policies on longer-term supply and demand profiles. As required by IAS 36, the additional value that could be obtained from enhancing the Group's assets and the potential benefit of any future restructuring or reorganisation that the Group is not yet committed to, is not reflectedin the ViU calculation. In determining ViU, the estimated future cash flows are discounted to present value using a pre-tax nominaldiscount rate reflecting the specific risks attributable to the asset or CGU in question. When calculating FVLCD, the method most appropriate for an individual asset or CGU is considered. This is generally either based on available market information on prices or comparable transactions, or a discounted cashflow method, similar to ViU, but including the impact of all relevant factors a market participant would consider. If the recoverable amount is less than the carrying amount in the Consolidated financial statements, an impairmentcharge is recognised to reduce the carrying amount of the asset or CGU to the estimated recoverable amount. Any impairment loss is recognised immediately in the Consolidated income statement. Individual assets are considered for impairment where possible. If individual assets do not generate cash inflowsthat are largely independent, the recoverable amount is determined for the CGU to which the asset belongs.Where possible, corporate assets are allocated to an individual CGU on a reasonable and consistent basis. Where

Page 26

corporate assets cannot be allocated to an individual CGU on a reasonable and consistent basis, they areincluded in the carrying amount of the smallest group of CGUs to which they can be allocated on a reasonable and consistent basis. An impairment loss relating to a CGU is allocated first to the carrying amount of any goodwill allocated to the CGUand then to the other assets pro-rata on the basis of the carrying amount of each asset. When allocating animpairment loss to the other assets in the CGU, if the recoverable amount of an individual asset within that CGU is determinable, the impairment loss allocated to the individual asset is limited to reducing the asset's carrying valueto its individual recoverable amount. If this results in the impairment loss allocated to an asset being less than itspro-rata share, the excess is allocated on a pro-rata basis to the remaining assets in the CGU. An impairment loss recognised for goodwill is not reversed in a subsequent period. Non-financial assets other than goodwill that havean impairment loss recognised are reviewed in subsequent reporting periods for possible reversal of theimpairment. Where an impairment reversal is identified, this is reversed immediately in the Consolidated income statement. The table below details the Group's reportable segments, the CGUs within those segments and the value of anygoodwill allocated to them. CGUs Segment name CGUs contained within segment As at 31 December 2025 Goodwill£m Pellet Production Northern Pellets - Biomass (Southern Pellets) 156.7 Biomass Generation Biomass (Drax Power Station) - Flexible Generation Lanark 11.3 Galloway 40.1 Cruachan 26.9 Hirwaun - Millbrook - Progress - Daldowie - Energy Solutions Drax Energy Solutions 161.2 Opus Energy - 396.2 Previously, the Group's pellet production activities in Canada and the US formed a single CGU (Pellet Operations),reflecting management's integration of the Group's Canadian and US pellet plants into one combined businessfollowing the Pinnacle acquisition in 2021, with pellets from the Canadian pellet plants (Northern Pellets) and the US pellet plants (Southern Pellets) being used interchangeably to fulfil third-party customer contracts and internallyat Drax Power Station, with biomass generation forming a separate CGU (Drax Power Station). During 2025,market conditions changed significantly. Expected future demand for biomass pellets declined following changes to the UK support schemes, with reduced volumes under the low carbon dispatchable CfD agreed in November2025, despite this agreement providing greater certainty over the future of Drax Power Station. At the same time,global pellet supply increased, particularly from Southeast Asia, and Canadian fibre availability was affected by tariffs. In the second half of 2025, the Group restructured its pellet operations, with its US pellet plants nowdedicated to supplying Drax Power Station and its Canadian pellet plants focused on third-party customers. Thisoperational change required a reassessment of the Groups CGUs and resulted in Northern Pellets and Southern Pellets being assessed separately, as their cash flows are now independent. The Group's US pellet plants now operate solely to supply Drax Power Station, and therefore do not generate cashinflows independently from Drax Power Station. Due to their whole output being used internally, and the absenceof an active external market for their output, from 2025, the US pellet plants and the biomass generation activities at Drax Power Station are assessed together as a single Biomass CGU. Goodwill arising from the 2021 Pinnacle acquisition was previously allocated to the Pellet Operations CGU.Following the change in CGU structure, this goodwill has been reallocated between Northern Pellets and SouthernPellets using a relative fair value approach, in accordance with IAS 36. This resulted in C$15.7 million (£8.4 million based on exchange rates at the time of reallocation) being allocated to Northern Pellets and US$210.8 million(£156.7 million based on exchange rates at the time of reallocation) being allocated to Southern Pellets. AsSouthern Pellets is within the Pellet Production segment but forms part of the Biomass CGU, goodwill allocated to Southern Pellets is also tested at the Southern Pellets level to ensure allocation and testing of goodwill does nottake place at a level higher than an operating segment. There are no changes to any other CGUs from the prior year. In respect of the Flexible Generation segment, the Group generally considers the smallest groups of assets thatgenerate independent cash inflows to be the individual sites that share common infrastructure and control functions. In respect of the Energy Solutions segment, the smallest groups of assets that generate independent cash inflowsare the operating entities within the business, Drax Energy Solutions and Opus Energy.

The Group's Innovation, capital projects and other operations provides central support functions to the Group'smain business activities and does not earn revenues and therefore does not meet the definition of a CGU. However, as explained above, corporate assets are considered for impairment individually where possible or aspart of a CGU, and relevant centrally managed costs are allocated to each CGU on a reasonable and consistentbasis. Assessment of indicators of impairment for CGUs to which no goodwill is allocated Full impairment reviews were performed on all CGUs to which goodwill had been allocated (see Impairment reviewsection below). For CGUs to which no goodwill is allocated, impairment reviews are only performed if impairmentindicators are identified. In determining whether impairment indicators existed in respect of these CGUs, the Group considered changes in market prices for commodities, foreign currency exchange rates, changes in macro-economic conditions, potentialimpacts of climate change and regulatory requirements since the previous reporting date, and their potentialimpact on the Group's long-term planning models and future forecast cash flows. Given the relatively consistent macro-economic conditions compared to the prior year end, as well as falling interest rates, these are notconsidered to be impairment indicators. Commodity prices have been relatively stable (e.g. power and gas) sincethe prior year end. The Group's generation activities in CGUs to which no goodwill is allocated are less sensitive to power price changes due to generation activities being more dependent on the spread between gas and powerprices. Further, a high proportion of the Group's income is not linked to power prices, such as income fromrenewable certificates, system support and ancillary services. From the factors considered above, no impairment indicators were noted. Whilst the commissioning date for the assets in the Hirwaun, Millbrook and Progress CGUs have been delayed,this was not considered an impairment indicator as the cash flow impact of these delays is not significant. There were no impairment indicators present for the Opus Energy, Hirwaun, Millbrook, Progress or DaldowieCGUs and accordingly no impairment review was performed for these CGUs in the current year. Impairment reviewFor the purpose of impairment reviews, the recoverable amounts of the CGUs, or groups of CGUs, are measured using ViU or FVLCD. ViU is calculated based on a discounted cash flow method using the Group's establishedplanning models. FVLCD uses a market price or comparable recent market transaction where possible. Where thisinformation is not available FVLCD is also based on a discounted cash flow method using the Group's established planning models as a base, but adjusting for impacts or changes that a market participant would factor in. Thesecalculations depend on a broad range of assumptions, the most significant of which are outlined below for eachCGU, or group of CGUs, to which an impairment test has been performed in the current year. The bases of these estimates are outlined below.

For the Northern Pellets CGU, FVLCD was higher than ViU. FVLCD was determined by discounting the post-taxcash flows that a third-party market participant would be expected to be able to generate from the CGU, less any costs of disposal. The cash flows used in calculating the FVLCD were based on management's detailed cash flowsin the Group's established planning models, but adjusted for changes, primarily to reduce central costs, that amarket participant with a different structure and requirements would be able to achieve. For the Drax Energy Solutions CGU, management has projected detailed cash flows based on a period of five years, with cash flows beyond the five-year period taken into perpetuity using a long-term growth rate of 2%. Forall other CGUs, management has projected detailed cash flows based on a period of 15 years, except for theBiomass CGU whose cash flows are forecast for 14 years in line with the useful economic life of Drax Power Station, which is to 2039. Whilst these periods are longer than the five-year period specified by IAS 36, and theperiod the Group assesses viability over in the Viability statement, they align with the Group's long-term strategicplanning and takes into account future structural changes forecast within the generation and pellet production industries, as well as expected developments in the pellet production industry. These longer-term structuralchanges are mainly linked to climate change and the impact of changing weather patterns (including increasedrain fall from storms and drier summer months for the run-of-river hydro CGUs and the impact on plant downtime and supply chains due to extreme weather events for the Northern Pellets and Biomass CGUs), the impact ofdecarbonisation and the transition to more renewable forms of energy and Net Zero, the impact of subsidy andsupport regimes, and the impact of repairs and maintenance expenditure which is not uniform across the lives of assets. Using a period of only five years for detailed cash flow forecasts could materially overstate or understatethe recoverable amounts of these CGUs as the impact of these factors in periods after five years can besignificant. The Northern Pellets CGU also has long term contracts that can be in excess of 10 years which further supports using a period greater than five years. Where possible, for relevant commodities, forecasts are based on either contracted prices, particularly for theNorthern Pellets and Biomass CGUs where the Group has a number of longer-term contracts to support the pricesused, or observable market curves. Beyond the liquid portion of forward curves, internally constructed price curves are benchmarked against third-party market analysis to validate the reasonableness of the assumptions used.Management continually reassesses forecasting accuracy, considering changes in circumstances and whetherforecasting differences were as a result of events that could not reasonably be foreseen at the date of the forecast. These reviews support the accuracy of management's forecasts. This supports the use of detailed forecast periodsof longer than five years. Where management has projected detailed cash flows based on a period of 15 years (Northern Pellets, Lanark,Galloway and Cruachan), cash flows beyond the 15-year period are taken into perpetuity using a long-term growthrate of 2%. The long-term growth rate is based on prudent expectations of market share and profitability along with more general macro-economic factors which were obtained from the Group's established planning model alongwith external macro-economic forecasts. The long-term growth rate does not exceed the relevant long-termaverage growth rate for each of the industries in which the Group operates. The discount rates used for each CGU are calculated with input from third-party experts and reflect the weighted average cost of capital derived using the Capital Asset Pricing Model (CAPM). The estimations use a risk-free ratebased on Government bonds, market participant capital structures and beta estimates adjusted for the specificcircumstances and risk factors affecting the industry and markets in which the CGU operates (taking into account relevant peer data sets). The CAPM calculates a post-tax discount rate which is applied to post-tax cash flows. Aniterative computation using pre-tax cash flows is then performed to derive an equivalent pre-tax discount rate. Further details on the assessments for each group of CGU as well as sensitivities for reasonably possible changesin key assumptions at the date of the impairment test are given below. Where reasonably possible changes in key assumptions would result in a material adjustment to the carrying value of a CGU, these are disclosed as a keysource of estimation uncertainty. The carrying amount, length of detailed cash flows, pre-tax discount rate and the perpetuity growth rate, whereapplicable, used in the calculation of each CGU's recoverable amount are set out in the table below: CGU Carryingamountincludingallocatedgoodwill£m Length ofdetailedcash flows£m Pre-taxdiscountrate Perpetuitygrowth rate Northern Pellets 84.2 15 years 19.3% 2.0% Biomass 1,412.3 14 years 11.5% n/a Drax Energy Solutions 178.2 5 years 9.2% 2.0% Lanark 44.3 15 years 8.0% 2.0% Galloway 174.2 15 years 8.0% 2.0% Cruachan 298.6 15 years 8.0% 2.0% Northern PelletsThe Northern Pellets CGU produces and sells biomass pellets to third-party customers. Market conditions during2025 significantly reduced expected future demand, driven by changes and expiries in UK and Dutch support schemes, including lower contracted volumes under the low carbon dispatchable CfD effective from April 2027.Global supply has also increased, particularly from Southeast Asia, and fibre availability in Canada has beenaffected by tariffs. As a result, Northern Pellets has refocused on third-party sales, and expectations for its future growth have reduced. The recoverable amount of the CGU, based on FVLCD, was less than its carrying value of £278.3 million, resultingin an impairment charge of £194.1 million. Assets for which ViU is determinable or FVLCD is measurable have notbeen impaired below these values. Goodwill was written down to £nil, with the remaining impairment allocated

Page 30

across other assets on a pro-rata basis. This resulted in an impairment of £8.5 million being allocated to goodwilland £185.6 million to other assets. Following the impairment, the CGU's carrying value equals its recoverable amount. Assets with determinable fair values above their carrying value were not impaired, while assets without a measurable recoverable amount werewritten down to £nil. The carrying value remains sensitive to key assumptions in the FVLCD model. Reasonably possible downside changes in assumptions from those used in the FVLCD calculation include a 50%reduction in assumed central cost savings, combined with a 7% decrease in pellet sales contract renewal prices, an increase in the pre-tax discount rate from 19.3% to 30.8% (equivalent to an increase in the post-tax discountrate from 15.0% to 18.0%), and a reasonably possible 30% decrease in the fair value determined for the individualassets that were not allocated an impairment loss. This combination of reasonably possible changes would result in an increase in the impairment recognised of £27.1 million and a corresponding reduction in the carrying value ofthe Northern Pellets CGU. Reasonably possible upside changes in assumptions from those used in the FVLCD calculation include a 7%increase in pellet sales contract renewal prices, combined with a decrease in the pre-tax discount rate from 19.3% to 15.0% (equivalent to a decrease in the post-tax discount rate from 15.0% to 12.0%). This combination ofreasonably possible changes would result in a reduction in the impairment recognised of £72.6 million and acorresponding increase in the carrying value of the Northern Pellets CGU. Accordingly, the FVLCD assumptions for this CGU have been identified as a key source of estimation uncertainty. Biomass The Biomass CGU is principally focused on renewable biomass electricity generation, including its integratedpellet supply chain. Given the allocated goodwill, a full impairment assessment has been performed. The cashflows between April 2027 and March 2031 reflect management's best estimate of earnings based on the terms of the low carbon dispatchable CfD agreement signed in November 2025. The expected income beyond March 2031to the cessation of operations in 2039, in line with the current end of station life of Drax Power Station, is based onthe assumption that earnings will continue at a similar level to those under the low carbon dispatchable CfD. Novalue has currently been included in the ViU calculation for disposing of the site and assets in 2039 due to the uncertainty over the value that could be achieved as a result of a lack of comparable transactions for a large-scalegeneration site with a live grid connection. If a value was included this would further increase the headroom. The ViU of the Biomass CGU was in excess of its carrying amount. The ViU of Southern Pellets was also inexcess of its carrying amount when testing the goodwill allocated to Southern Pellets at a segment level or below. The Biomass CGU has a carrying value at 31 December 2025 of £1,412.3 million. A combination of reasonably possible changes in certain assumptions used in the value in use model could lead to a material adjustment to thiscarrying value. These include: an average 27% decrease in power prices over the period of the low carbon dispatchable CfDagreement from April 2027 to March 2031, combined with a 90-day outage of one of the units under the Renewables Obligation scheme in 2026, an increase in biomass production costs of US$7 per tonne, an increasein the pre-tax discount rate from 11.5% to 23.7% (equivalent to an increase in the post-tax discount rate from 7.5%to 8.3%), and operations to cease in March 2031 at the end of the low carbon dispatchable CfD agreement. This combination of reasonably possible changes in the key inputs to the value in use model would lead to animpairment of £650.1 million. Therefore, reasonably possible assumptions in the ViU calculation of the BiomassCGU have been identified as a key source of estimation uncertainty. Drax Energy Solutions This segment is principally focused on renewable electricity sales to industrial and commercial (I&C) customersand providing other renewables services. The ViU of the Drax Energy Solutions CGU was in excess of its carrying amount. A reasonably possible increasein the pre-tax discount rate to 12.5% combined with factoring in a reduction in forecast gross margin by 10%, 0% perpetuity growth rate and a reduction in growth of forecast income from the electric vehicles business, equivalentto a 50% reduction in future forecast earnings, would reduce the headroom by £331.0 million. This would not resultin an impairment. Whilst reasonably possible changes in assumptions would reduce the headroom, they would not result in the recoverable amount being lower than the carrying value. As such management does not believe thatany reasonably possible changes in the key assumptions would result in an adjustment to the carrying value of theDrax Energy Solutions CGU. Lanark, Galloway and Cruachan These CGUs are engaged in run-of-river hydro and pumped storage power generation. The ViU for all three CGUs(Lanark, Galloway and Cruachan) were in excess of their carrying amounts. For the Cruachan CGU, a reasonably possible 25% average power price reduction combined with an increase inthe pre-tax discount rate to 8.7%, and less favourable weather patterns, resulting in a reduction in value from market volatility, would reduce the headroom by £758.2 million. This would not result in an impairment. For theLanark CGU, a reasonably possible 25% average power price reduction combined with an increase in the pre-taxdiscount rate to 8.7% and a low rainfall year, based on historical lows, every one in three years, would reduce the headroom by £26.3 million. This would not result in an impairment. Whilst reasonably possible changes inassumptions for the Lanark and Cruachan CGUs would reduce the headroom, they would not result in therecoverable amounts being lower than the carrying values. As such the Group does not believe that any reasonably possible changes in the key assumptions would result in an adjustment to the carrying values of eitherthe Lanark or Cruachan CGUs. For the Galloway CGU, a reasonably possible 25% average power price reduction combined with an increase inthe pre-tax discount rate to 8.7% and a low rainfall year, based on historical lows, every one in three years, would result in an impairment of £5.9 million. The Galloway CGU is sensitive to reasonably possible changes in the keyassumptions. Whilst reasonably possible changes to assumptions would result in an adjustment to the carrying

Page 31

value of the Galloway CGU, they would not result in a material adjustment to its carrying value and so it is notconsidered a key source of estimation uncertainty as defined by IAS 1. Impairment of non-current assets LongviewDuring 2025, an impairment loss of £108.8 million has been recognised relating to the Group's Longview pelletplant development project (Longview). Due to reduced expectations around global pellet demand in the short to medium term, in part as a result of the reduced volumes of biomass generation agreed under the low carbondispatchable CfD contract, the decision has been taken to pause this development and no development of the siteis expected in the near term. The capitalised Longview assets have been impaired to their recoverable amount of £13.7 million (principally the value of the land at the site). This recoverable amount has been estimated after considering the level ofcustomisation and general market conditions. If the Group is able to return assets to suppliers; or achieve third-party sales; or find internal use for parts and spares at the Group's other pellet plants; or if any scrap value achieved exceeds the costs of disposal, then the recovery value could be higher. If an average recovery value of40% on plant and equipment had been assumed, this would result in a decrease in the impairment recognised of£29.5 million and a corresponding increase in the carrying value of the Longview assets. As such the assumptions regarding the recoverable amount of Longview plant and equipment have been identified as a key source of estimation uncertainty. A separate onerous contract provision for the Longview fibre purchase contracts has been recognised. UK BECCSGiven the current political environment and the lack of development of an appropriate regulatory framework tosupport the investment required for UK BECCS, the Group has refocused its investment priorities on nearer term opportunities with more balanced risk-return profiles and therefore has rationalised its level of investment in carboncapture opportunities. Whilst UK BECCS is still an attractive option for the Group long term and management stillbelieves that the development of BECCS at Drax Power Station is important to the UK's Net Zero strategy, the fullcarrying amount of the development project of £47.6 million has been impaired due to the reduced likelihood of the project proceeding in the short to medium term. Although not expected in the near term, if an appropriateregulatory framework were to be developed and the political environment was to become more supportive of large-scale capital investment in UK BECCS, increasing the likelihood of the project progressing, a reversal of the impairment of certain UK BECCS costs may be required.

See note 4 for further details. 4. Alternative performance measures This note provides details of all APMs used, each APM's closest IFRS equivalent, the reason why the APM is usedby the Group and a definition of how each APM is calculated. The Group presents Adjusted results in the Consolidated income statement. Management believes that thisapproach is useful as it provides a clear and consistent view of underlying trading performance. Exceptional items and certain remeasurements are excluded from Adjusted results and are presented in a separate column in theConsolidated income statement. The Group believes that this presentation provides useful information about thefinancial performance of the business and is consistent with the way the Board and executive management assess the performance of the business. The Group has a policy and framework for the determination of transactions to be presented as exceptional.Exceptional items are excluded from Adjusted results as they are transactions that are deemed to be one-off orunlikely to reoccur in future years due to their nature, size, the expected frequency of similar events, or the commercial context. By excluding these amounts, this provides users of the Consolidated financial statements witha more representative view of the results of the Group and enables comparisons with other reporting periods as itexcludes amounts from activities or transactions that are not likely to reoccur. All transactions presented as exceptional are approved by the Audit Committee. In these Consolidated financial statements, the following transactions have been designated as exceptional itemsand presented separately:

- Opus Energy sale of meter points and restructuring: Costs and credits arising as a result of the transaction to sellthe majority of the non-core Opus Energy SME customer meter points and related strategic restructuring to reflect the reduced size of the Opus Energy SME business and Energy Solutions' focus on core I&C customersand renewables services (Energy Solutions, 2024 and 2025). See below for further details.- Impairment of Longview and related costs: Asset impairment charges of £108.8 million (see note 3), the recognition of provisions for onerous fibre contracts of £22.0 million and £8.1 million of other costs relating to theGroup's decision to pause the Longview development project (Pellet Production, 2025).- Impairment of UK BECCS: Impairment of capitalised development costs relating to the Group's UK BECCS development project (Biomass Generation, 2025). See note 3 for further details.- Impairment of Northern Pellets CGU and related costs: Asset impairment charges of £194.1 million (see note 3)and related costs of £3.7 million within the Group's Northern Pellets business (Pellet Production, 2025). See note 3 for further details on the impairment of the Northern Pellets CGU.- Change in the fair value of contingent consideration (Flexible Generation, 2025).- Transformation and restructuring (all segments, 2025). See below for further details. Certain remeasurements comprise fair value gains and losses on derivative contracts to the extent that those contracts do not qualify for hedge accounting, or hedge accounting is not effective, and those gains or losses areeither i) unrealised and relate to derivative contracts with a maturity in future periods, or ii) are realised in relationto the maturity of derivative contracts in the current period. Management believes adjusting for fair value gains and losses recognised on derivative contracts provides users of the Consolidated financial statements with usefulinformation, as this removes volatility caused by movements in market prices over the life of the derivativecontracts. Gains and losses on derivative contracts prior to maturity generally reflect the difference between the contracted price and the current market price, which management does not believe provides meaningfulinformation as the Group is not entering contracts with the intention of creating value from changes in marketprices. The Group regards all of its forward contracting activity to represent economic hedges to secure prices and rates, and lock in value for its future expected pellet production, generation or energy supply activities. The contractedprice is therefore deemed relevant and representative of the Group and its performance, rather than how thecontracted price compares to prevailing market prices, as the Group is not seeking to make trading profits on these derivative contracts through market price movements. The effect of excluding certain remeasurements fromAdjusted results is that commodity sales and purchases are recognised in Adjusted results in the period they areintended to hedge at their contracted prices i.e. at the all-in-hedged amount paid or received in respect of thedelivery of the commodity in question. It also results in the total impact of financial contracts being recognised in Adjusted results on maturity, being the period they are intended to hedge. Management believes this better reflectsthe performance of the business as it more accurately represents the intention for entering derivative contracts. Movements on derivative financial instruments which do not qualify for hedge accounting, or where hedgeaccounting is ineffective, are shown in the table below. During 2025 the amounts recognised were predominantly due to fair value gains recognised on foreign exchange contracts on matured trades, due to GBP weakeningagainst USD when compared to the original trade dates, and the realisation of losses on maturity of inflation andcommodity hedges. Further details on the Group's derivative financial instruments are provided in Section 7. The effective tax rate on exceptional items of 2.2% during the current year is lower than the standard corporation tax rate applicable in the relevant jurisdictions as a result of the non-deductibility of the impairment of non-currentassets within the Northern Pellets CGU, and the related derecognition of deferred tax assets in Canada as a resultof this. The Group does not believe tax deductions will be recognised for these items in the future.

All SME supply meter points have now been disposed of. An employee consultationprocess has also been completed resulting in a reduction in headcount to reflect a focus on core industrial andcommercial (I&C) and renewables services. The Group incurred costs of redundancies in order to reduce the headcount in the Opus Energy business and holds a redundancy provision at 31 December 2025 in respect of inscope colleagues who had not yet left the Group. The gains and losses described above that have been recognised in the period on the transaction and relatedrestructuring have been classified as exceptional.

The cash flows relating to the transaction havebeen recognised within operating cash flows in the Consolidated cash flow statement. Transformation and restructuringThe Group has commenced a significant transformation programme ("Future Focus") centred around growth, efficiency and performance culture. As part of this programme, the organisational structure has been redesigned inorder to deliver an appropriate cost base under the low carbon dispatchable CfD agreement from April 2027. Thistransformation programme commenced in 2025 and is expected to run through to the end of 2026. The costs incurred in the year primarily relate to employee severance costs and related consultancy costs.

APM Closest IFRSequivalent measurePurpose Definition Adjustedresults Total results The Group's Adjusted results areconsistent with the way the Board andexecutive management assess theperformance of the Group. Adjustedresults are intended to reflect theunderlying trading performance of theGroup's businesses and are presentedto assist users of the Consolidatedfinancial statements in evaluating theGroup's trading performance andperformance against strategic objectiveson a consistent basis. Adjusted results excludes exceptionalitems and certain remeasurements. Exceptional items are those transactionsthat, by their nature, do not reflect thetrading performance of the Group in theperiod. Certain remeasurements comprise fairvalue gains and losses that do notqualify for hedge accounting (or hedgeaccounting is not effective). The Groupregards all of its forward contractingactivity to represent economic hedgesand therefore by excluding the volatilitycaused by recognising fair value gainsand losses prior to maturity of thecontracts, the Group can reflect thesecontracts at the contracted prices onmaturity, reflecting the intended purposeof entering these contracts and theGroup's underlying performance. Adjusted results are the metrics used inthe calculation of Adjusted basic EPSand Adjusted diluted EPS. Total results measured in accordance withIFRS excluding the impact of exceptionalitems and certain remeasurements. Exceptional items and certainremeasurements are defined above. AdjustedEBITDA Operating profit(1) Adjusted EBITDA is the primarymeasure used by the Board andexecutive management to assess thefinancial performance of the Group as itprovides a more comparableassessment of the Group's year-on-yeartrading performance. It is also a keymetric used by the investor communityto assess the performance of theGroup's operations. Earnings before interest, tax, depreciation,amortisation, other gains and losses andimpairment of non-current assets,excluding the impact of exceptional itemsand certain remeasurements. Adjusted EBITDA excludes any earningsfrom associates or attributable tonon ‑ controlling interests. Adjustedbasic EPS Basic EPS Adjusted basic EPS represents theamount of Adjusted earnings (Adjustedprofit after tax) attributable to eachordinary share outstanding. Adjusted basic EPS is calculated bydividing the Group's Adjusted earningsattributable to owners of the parentcompany (Adjusted profit after tax) by theweighted average number of ordinaryshares outstanding during the period. Adjusteddiluted EPS Diluted EPS Adjusted diluted EPS demonstrates theimpact upon the Adjusted basic EPS ifall outstanding share options, that areexpected to vest on their future maturitydates and where the shares areconsidered to be dilutive, were exercisedand treated as ordinary shares as at thereporting date. Adjusted diluted EPS is calculated bydividing the Group's Adjusted earnings(Adjusted profit after tax) attributableto owners of the parent company by theweighted average number of ordinaryshares outstanding during the period anddilutive potential ordinary sharesoutstanding under share plans during theperiod. Borrowings n/a(2) Borrowings provides information relatingto the Group's use of debt. It is a keymeasure of leverage and providesinformation on the sources of liquidity forthe Group. Borrowings includes external financialdebt, such as loan notes, term loans andamounts drawn in cash under revolvingcredit facilities (RCFs). Borrowings doesnot include other financial liabilities suchas pension obligations, trade and otherpayables including supply chain finance,lease liabilities calculated in accordancewith IFRS 16, and working capital facilitieslinked directly to specific payables (suchas credit cards and deferred letters ofcredit) that provide a short extension ofpayment terms of less than 12 months(see note 5).

APM Closest IFRSequivalent measurePurpose Definition Net debt Borrowingsand leaseliabilities lesscash andcashequivalents Net debt is a key measure of theGroup's liquidity and its ability tomanage its financial obligations. Net debt is used as a basis by debtrating agencies to assess credit risk, andin the calculation of the Group's financialcovenant requirements. The impact of hedging instrumentsincluded within Net debt shows theeconomic substance of the Net debtposition, in terms of actual expectedfuture cash flows to settle that debt. Borrowings (as defined above) includingthe impact of hedging instruments, andlease liabilities calculated in accordancewith IFRS 16 less cash and cashequivalents. Net debt excludes the proportion of cash,lease liabilities and borrowings in non-wholly owned entities that would beattributable to the non-controllinginterests. Net debt includes the impact of foreigncurrency hedging instruments, meaningthat any borrowings that have associatedhedging instruments in place are adjustedto reflect those borrowings at the hedgedrate. Net debt includes the impact of any cashcollateral receipts from counterparties orcash collateral posted to counterparties. Net debt toAdjustedEBITDA ratio Borrowingsand leaseliabilities lesscash andcashequivalentsdivided byoperating profit(1) The Net debt to Adjusted EBITDA ratio isa debt ratio that gives an indication ofhow many years it would take the Groupto pay back its debt if Net debt andAdjusted EBITDA are held constant. The Group has a long-term target forNet debt to Adjusted EBITDA of around2.0 times. Net debt divided by Adjusted EBITDA forthe last twelve months expressed as amultiple.

PPE additions plus intangible assetadditions, excluding capitalised borrowingcosts and capital plant spare additions. (1) Operating profit is presented in the Group's Consolidated income statement; however, it is not defined per IFRS. It is a generally acceptedmeasure of profit.(2) Borrowings are presented in the Group's Consolidated balance sheet; they are a commonly used balance sheet line item heading; however, borrowings are not defined by IFRS, therefore the Group's borrowings may not be comparable to borrowings presented by othercompanies.(3) During 2025, the definition of Capital expenditure has been updated to align with the way the information is currently presented to theBoard and executive management. The definition now excludes capitalised borrowing costs and capital plant spare additions. See the capital expenditure by segment table in note 1 for further details of this change. 5. Notes to the Consolidated cash flow statementAccounting policyIn accordance with IAS 7 the Group has elected to classify cash flows from interest paid and interest received ascash flows from operating activities, dividends paid as cash flows from financing activities, and dividends received as cash flows from investing activities. The interest repayments on lease liabilities are included within interest paid,and the lease principal repayments are presented within cash flows from financing activities. Payments for short-term and low value leases are included within cash flows from operating activities. Cash generated from operations Cash generated from operations is the starting point of the Group's Consolidated cash flow statement.

These costs are presented within staff costs within operating and administrative expenses in the Consolidated income statement.(2) Certain remeasurements of derivative contracts includes the effect of non-cash unrealised gains and losses recognised in theConsolidated income statement and their subsequent cash realisation. It also includes the cash and non-cash impact of deferring and recycling gains and losses on derivative contracts designated into hedge relationships under IFRS 9, where the gain or loss is held in thehedge reserve and then released to the Consolidated income statement in the period the hedged transaction occurs. The most significant factors contributing to cash generated from operations are explained in further detail below. The £23.4 million inflow due to the adjustment for certain remeasurements for derivative contracts in the currentyear (2024: £89.3 million outflow) mainly relates to unrealised fair value losses (2024: unrealised fair value gains)on open derivative contracts offset by cash payments on maturing trades. Cash collateral is sometimes paid or received in relation to the Group's commodity and treasury trading activities. When derivative positions are out of the money for the Group, collateral may be required to be paid to thecounterparty. When derivative positions are in the money, collateral may be received from counterparties. Thesepositions reverse when mark-to-market positions reduce, or contracts are settled, and the collateral is returned. The Group has had a net cash outflow of £24.5 million from derivative-related collateral during the year, as trades have matured and mark-to-market positions have reduced (2024: £83.7 million inflow). As at 31 December 2025,the Group held £nil (2024: £9.8 million) in cash collateral receipts recognised in payables, and had posted £19.4million (2024: £4.7 million) of cash collateral payments recognised in receivables. The Group actively manages its liquidity requirements. This includes managing collateral associated with the hedging of power and other commodities, as well as other contractual arrangements. Under certain arrangementsthe Group is able to use non-cash collateral, such as letters of credit and surety bonds, that may otherwise haverequired cash collateral. The Group utilised £14.5 million (2024: £14.5 million) of letters of credit and £20.0 million (2024: £30.0 million) of surety bonds to cover commodity trading collateral requirements. Letters of credit andsurety bonds utilised at the reporting date have reduced the requirement for cash collateral payments, which hasincreased the amount by which receivables have decreased. The Group has a strong focus on cash flow discipline and managing liquidity. The Group enhances its working capital position by managing payables, receivables, inventories and renewable certificate assets to make sure theworking capital committed is closely aligned with operational requirements. The impact of these actions on thecash flows of the Group is included within the further detail explained below. The table below sets out the key arrangements utilised by the Group to manage elements of its working capital: As at31 December2025£m As at31 December2024£m Inflow/(outflow)£m Receivables monetisation 348.4(1) 400.0 (51.6) ROC monetisation sales 50.0 - 50.0

Deferred letters of credit (73.2) (150.3) (77.1) (1) As at 31 December 2025 the Group had sold £275.6 million (2024: £386.3 million) of receivables under this facility. At 31 December 2025 the Group had recognised an amount payable to the facility provider of £72.8 million (2024: £13.7 million), being the movement in thereceivables sold compared to the prior month. This amount was paid to the facility provider in January 2026, so as at 31 December 2025the utilisation of the facility was £348.4 million (2024: £400.0 million). None of the balances in the table above are included within the Group's definition of Net debt or borrowings (seenote 4 for further details on Net debt). The receivables monetisation facility is non-recourse in nature and therefore there is no future liability associated with these amounts. Through standard ROC sales and ROC purchasearrangements the Group is able to manage the working capital cycle of inflows and outflows of these assets. Thesupply chain finance and deferred letters of credit facilities are linked directly to specific payables. The deferred letters of credit facilities provide a short extension of payment terms of less than 12 months. The impact of thesefacilities on the cash flows of the Group is explained further below. The cash inflow of £76.5 million (2024: £25.2 million) as a result of the decrease in inventories primarily resultsfrom higher generation in December at Drax Power Station and the timing of shipments. The overall cash inflow of £136.2 million (2024: £392.2 million) due to lower receivables in the current year is primarily a result of a reduction in energy prices compared to the prior year. The Energy Solutions segment has access to a receivables monetisation facility which enables it to acceleratecash flows associated with amounts receivable from energy supply customers on a non-recourse basis. During theyear the maturity of the facility was extended to March 2030, from March 2027. The Group now has the option to set the facility limit between £300.0 million and £400.0 million, subject to lender approval. Upon the Group'srequest, the lender agreed to reduce the facility limit to £350.0 million from August 2025 in line with the lowerreceivables balances in the Energy Solutions business. The limit was £350.0 million as at 31 December 2025 (31 December 2024: £400.0 million). Payables have decreased from the prior year, with a cash outflow of £110.2 million (2024: £142.7 million). This isdue to a reduction in other payables as the deferred letters of credit have reduced in relation to OCGT capitalexpenditure now that the assets are nearing completion. The decrease in payables is also due to the reduction in energy supply accruals compared to the prior year as the value of REGOs has reduced year-on-year. Certain ofthe Group's suppliers are able to access a supply chain finance facility provided by a bank, for which funds can beaccelerated in advance of normal payment terms. At 31 December 2025, the Group had trade payables of £62.6 million (2024: £38.4 million) related to this. The facility does not directly impact the Group's working capital, aspayment terms remain unaltered with the Group and would remain the same should the facility fall away. The Group also has access to deferred letters of credit facilities under which the Group benefits from an extensionto payment terms of less than 12 months for a fee. The amount outstanding under these facilities at 31 December 2025 was £73.2 million (2024: £150.3 million). Of the total deferred letters of credit, £42.4 million (2024: £92.8million) were utilised for capital expenditure and £30.8 million (2024: £57.5 million) were utilised for trade payables.Utilisation of these payment facilities impacted the purchases of property, plant and equipment line in the Consolidated cash flow statement and the movement in payables line above. The movement in renewable certificate assets during the year includes a combination of generation, utilisation,purchases and sales. Cash from renewable certificates, and in particular ROCs, is typically realised severalmonths after they are earned; however, through standard ROC sales and ROC purchase arrangements the Group is able to manage the working capital cycle of inflows and outflows of these assets. At 31 December 2025, theGroup had cash inflows of £50.0 million (2024: £nil) from using these standard renewable certificate sales.

(1) Hedging instruments include both financial assets and financial liabilities used to hedge liabilities arising from financing activities. At 31December 2025 hedging instruments include £4.9 million (2024: £nil) of financial assets and £10.7 million (2024: £41.0 million) of financial liabilities. Other movements on borrowings principally relate to interest. Other movements on lease liabilities principally relate to discounting and additions in the year. Other movements on hedging instruments include cross-currencyinterest rate swaps that are hedging both principal and interest payments on borrowings. Interest payments areclassified as operating cash flows in the Consolidated cash flow statement. As such, fair value movements and cash settlements relating to the interest payments on these hedges are recognised within the other movementsline above. Other movements on obligation to purchase own shares represent an initial liability of £7.2 million and£0.1 million of interest charged in relation to this liability. 6. Equity and reserves The Group's ordinary share capital reflects the total number of shares in issue, which are publicly traded on theLondon Stock Exchange. Accounting policyOrdinary shares are classified as equity as evidenced by their residual interest in the assets of the Company after deducting its liabilities. Incremental costs directly attributable to the issue of new shares or options are shown inequity as a deduction, net of tax, from the proceeds. Issued equity As at 31 December 2025 £m 2024£m Issued and fully paid: 432,171,763 ordinary shares of 11 pence each(2024: 427,770,766) 49.9 49.4 The movement in allotted and fully paid share capital of the Company during the year was as follows: Year ended 31 December 2025(number) 2024(number) At 1 January 427,770,766 424,923,406 Issued in respect of employee share schemes 4,400,997 2,847,360 At 31 December 432,171,763 427,770,766 The Company has only one class of shares, which are ordinary shares of 11 pence each, carrying no right to fixed income. Throughout the year, shares were issued in satisfaction of options vesting in accordance with the rules of the Group's employee share schemes. During the year 2,611,059 shares were issued at a weighted average exercise price of 190.2 pence per share inrespect of options vesting on employee share purchase schemes and 1,789,938 shares were issued in respect ofshare options vesting on share awards with no exercise price. Own shares reserveThe own shares reserve represents shares of Drax Group plc purchased under share buyback programmes and held by the Company as Treasury shares, or shares of Drax Group plc held by the EBT for the purpose ofsatisfying employee share plan awards. The EBT is treated as an extension of the Company and therefore theGroup, in accordance with IFRS 10. The cost of the shares held by the EBT or the Company are recognised as a deduction from equity until the shares are issued to employees under share awards, cancelled, reissued or disposed of. The amount deducted fromequity includes any incremental directly attributable costs. No gain or loss is recognised in the Consolidatedincome statement on the purchase, sale, issue or cancellation of the Company's own equity instruments. Where the Company has entered into a forward contract and has an obligation to purchase a fixed amount of its ownshares for a fixed price, the present value of this obligation is recognised as a deduction to equity, within retainedearnings, and a corresponding liability is recognised. The unwinding of the discount is included in interest payable and similar charges in the Consolidated income statement. Once the shares have been received under thisforward contract, the deduction to equity within retained earnings is transferred to the own shares reserve. As at 31 December 2025, the own shares reserve comprises 91.8 million (2024: 57.8 million) shares at a value of£534.6 million (2024: £314.2 million) held in treasury, and nil (2024: nil) shares held by the EBT. During the year, the EBT subscribed for 1.8 million of new shares at nominal value for a total of £0.2 million, which were subsequently issued to employees to satisfy share plan awards during the year. Share buyback programmeOn 31 July 2025, the Group announced a £450 million share buyback programme, to commence immediatelyfollowing the completion of the £300 million share buyback programme that took place between 2024 and 2025.

Shares purchased under these share buyback programmes are held in treasury within the own shares reserveawaiting reissue or cancellation and have no voting rights attached to them. The shares purchased by the Group have not been cancelled and so continue to be included in the issued shares in the above table. Share premiumThe share premium account reflects amounts received in respect of issued share capital that exceeds the nominalvalue of the shares issued, net of incremental transaction costs and tax, that are directly attributable to the issue ofnew shares. Movements in the share premium reserve during the year reflect amounts received above the nominal value on the issue of shares under employee share schemes.

Dispatchable power An electricity generator produces dispatchable power when the power can be ramped up and down, or switchedon or off, at short notice to provide (or dispatch) a flexible response to changes in electricity demand. Biomass,pumped storage, coal, oil, and gas electricity generation can meet these criteria and hence can be dispatchable power sources. Nuclear can be dispatched against an agreed schedule but is not flexible. Wind and solarelectricity cannot be scheduled and hence are not dispatchable.
