The increase in revenue in 2025 is primarily attributable to higher distribution, transportation, green credit, and gas revenues. This growth was driven by increased consumption, higher electricity and gas prices across existing operating entities, and the acquisition of three new operating entities. The increase in expenses is driven by higher personnel, repair and maintenance, depreciation and amortisation, and fuel expenses.

Income tax expense for the year was $88 million (2024: $123 million) which represents an effective tax rate of 32.2% (2024: 45.7%). The decrease in the effective tax rate is due to thin cap denial on shareholder loan interest expense in the previous year not being applicable in the current year.

Profit after income tax expense for the year was $185 million (2024: $146 million). The increase is primarily due to the lower effective tax rate as documented above.

* Operating profit represents profit before income tax expense and finance expenses.

AGIH

AGIH's revenue decreased by $103 million, mainly due to lower transportation, distribution and gas revenues. Operating profit decreased by $104 million due to the decreased revenue.

EDL

EDL revenue decreased marginally by $34 million compared to prior year mainly due to unfavourable volume and pricing of green credits , and a decrease in gas revenue. Operating profit decreased by $91 million driven by lower revenue, higher depreciation on new assets, higher personnel expenses, repair and maintenance and other expenses.

UE

UE's revenue increased by $169 million mainly due to higher consumption in 2025. Operating profit increased by $129 million due to higher revenue.

PEGL

PEGL's revenue increased by $86 million due to a full year of the business being part of the group compared to 8 months in the previous year. Operating profit increased by $46 million due to a full year of the business being part of the group compared to 8 months in the previous year.

The consolidated entity continues to invest significantly in replacement and growth capital assets in each operating business to maintain strong operating results.

CK William UK Holdings Limited

Strategic report

31 December 2025

Safety management

Safety is our number one priority across the consolidated entity. This is measured using multiple KPIs across the consolidated entity. Each operating group implements policies and procedures to ensure safety and well-being of employees.



AGIH, MG and UKREG use lost time injuries to employees and contractors as a key KPI. During the year, the number of lost time injuries incurred was 4 against a target of 2 (2024: 4 lost time injuries against a target of 2).



AGIH and UE use significant health and safety incidents or potential fatal risk incidents as a key KPI. During the year, the number of potential fatal risk incidents incurred was 0, less than the target of 3 (2024: 11 potential fatal risk incidents against a target of 3).

Programs are in place to focus on continuing to improve safety performance across the consolidated entity. Further details on the Environmental, social and governance activities of the group have been documented in the ESG Report.

Reliability

Given the differences in operations across the CK William Group, there is no consistent reliability metric that is applied to each group, rather each group has a specific reliability KPI.



AGIH uses a variety of measures for the different types of gas businesses. DBP uses available hours for measuring reliability. UKREG uses wind turbine availability for measuring reliability. In 2025, DBP did meet their target reliability KPIs, and MG met two of their three reliability KPIs. The actual reliability performance is:

UE uses Service Target Performance Incentive Scheme results, which includes a financial impact from reliability of supply. UE achieved $17 million against a target of $10 million (2024: $16 million achieved against a target of $10 million).

Financial performance

Financial performance is discussed above on page 3.

Principal risks and uncertainties

Regulatory environment

The gas transmission, gas distribution and electricity distribution businesses within the group are subject to extensive legal and regulatory obligations, which the businesses must comply with. The possible changes in laws and regulatory standards could have an adverse effect on the operations and financial position of these businesses.

The consolidated entity mitigates this risk by having dedicated regulatory teams in each operating business which work closely with the regulator. In addition, dedicated compliance functions exist to ensure compliance obligations are performed.

Health and Safety

There is a risk that an incident within the operating businesses could lead to injury to an employee, contractor or member of the general public. Any such incident could have an adverse effect on the reputation of the operating business or lead to potential prosecution.

6

CK William UK Holdings Limited

Strategic report

31 December 2025

As Health and Safety is our number one priority, there are dedicated Health, Safety and Environment teams in the operating businesses who manage and monitor the safety systems and processes and adopts safety KPIs to monitor this. Each of the operating entities will roll out specific training to address key safety initiatives within their businesses.

Network Performance

If transmission or distribution network assets fail, it could result in a loss of supply to customers and associated adverse publicity. Significant outages can result in Guaranteed Service Level (GSL) payments to customers and in some cases, Service Target Performance Incentive Scheme (STPIS) penalties will apply.



This risk is mitigated by asset management procedures and network planning activities.

Macroeconomic environment

The consolidated entity provides essential services in gas transmission, gas distribution, electricity distribution and electricity generation. The regulated businesses are not materially impacted by the macroeconomic environment in the year marked by high inflation, high commodity prices and rising interest rates. The consolidated entity benefited from strong electricity prices in the electricity generation business in 2025.

High inflation risk

Inflation was high in 2025 in Australia, North America and Europe. In 2025 the largest inflationary increases were experienced in materials, parts and fuel expenses. The impact of high inflation on the consolidated entity's profitability is limited as inflation linked regulated revenue offsets the increase in expenses.

Transition to renewable energy

Our plan for transition to renewable energy is disclosed under Climate-related financial disclosures (CFD) which are included within the ESG report below.

Financial risk management

The consolidated entity's activities expose it to a variety of financial risks. The consolidated entity's overall risk management program focuses on the unpredictability of financial markets and seeks to minimise potential adverse effects on the financial performance of the consolidated entity. The consolidated entity uses derivative financial instruments to hedge interest rate, foreign exchange and commodity price risk exposures. Derivatives are exclusively used for hedging purposes, i.e. not as trading or other speculative instruments. Financial risk management is carried out by the operational entities' treasury functions under policies approved by the respective boards of directors. See note 33 for detailed disclosure around financial risk mitigation and hedging.

Interest rate risk

The consolidated entity is exposed to interest rate risk as it invests and borrows funds at both fixed and floating interest rates. The risks are managed by maintaining an appropriate mix between fixed and floating rate borrowings and through the use of interest rate swap contracts and forward interest rate contracts. Hedging activities are evaluated regularly to confirm alignment with the debt and liquidity management policies and ensure that the operating entities are not exposed to excess risk from interest rate volatility.



The impact of increasing interest rates in 2025 has been limited due to high level of interest rate hedging for external borrowings with variable rates.

Foreign exchange risk

The consolidated entity enters into borrowings denominated in foreign currencies and has overseas operations in foreign currencies. Risk of foreign borrowings are managed by taking out cross currency swaps.

Commodity price risk

The consolidated entity is exposed to unregulated market price fluctuations and enters into fixed price electricity contracts to reduce the volatility attributable to price fluctuations.

Streamlined Energy and Carbon Reporting (SECR)



PEGL is required to disclose their energy consumption and greenhouse gas (GHG) emissions, along with energy efficiency actions and the methodology used for calculations. This is disclosed in their financial statements which are publicly available on Companies House and available on their website: www.phoenixenergyni.com.

Climate-related financial disclosures

CK William UK Holdings Limited

Climate-related Financial Disclosures

For the year ended 31 December 2025

Basis of preparation

These disclosures have been prepared to address the UK climate-related financial disclosure requirements applicable to the strategic report. They focus on the information necessary to understand the Group’s exposure to climate-related risks and opportunities, rather than reproducing the full sustainability reports prepared by the business units.

CK William UK Holdings Limited “the Company” is a holding company. It does not have operational assets, employees or a standalone climate strategy. Substantially all climate-related risks and opportunities, greenhouse gas emissions, targets and related management actions arise in the underlying operating groups. Accordingly, detailed operating group disclosures are summarised and cross-referenced rather than repeated in full.

Management has reviewed the climate-related disclosures prepared by each qualifying subsidiary and operating group to assess whether the matters disclosed are relevant to the Company’s consolidated climate-related financial disclosures. This review considered the nature of the Company as a holding company, the location of operational control, the material climate-related risks and opportunities identified by each operating group, the metrics and targets reported at subsidiary level, and the extent to which those matters could affect the consolidated financial statements. On this basis, management concluded that a consolidated and condensed approach is appropriate because the Company’s climate-related risks, opportunities, metrics, targets and financial statement impacts arise through its investments in the operating groups, rather than through standalone holding company activities.

In preparing these disclosures, management summarised the subsidiary and operating group sustainability reports into a holding company-level climate-related financial disclosure by identifying common themes relevant to the consolidated group, retaining disaggregated information where necessary to avoid obscuring differences between sectors, geographies and regulatory regimes, and cross-referring to the underlying reports for detailed operating information. The condensed presentation is intended to provide sufficient information for users of the Company’s annual report to understand the Group’s exposure to climate-related risks and opportunities without duplicating detailed subsidiary disclosures that are more appropriately presented at operating group level.

The full sustainability report for each of the qualifying business units can be found through the following links:

Governance and risk management

Climate-related governance, risk identification, monitoring and management are delegated to the boards and management teams of the operating groups, where the relevant assets, operations, data and management actions reside. At holding company level, the Company Board retains oversight of climate-related matters to the extent they are relevant to the Company’s role as a holding company, including approval of the annual report and consideration of climate-related matters where they may affect investment, financing, impairment, going concern, capital allocation or the consolidated financial statements. The Board does not duplicate operating company governance structures and no director has a separate executive responsibility for managing climate-related risks and opportunities at holding company level.

The Directors review climate-related information as part of the annual reporting process and when climate matters are expected to have a material effect on the Company’s financial position, performance, strategy or prospects. This includes information summarised from operating group sustainability reports, climate-related risks and opportunities identified by operating group management, emissions metrics and targets, progress against material targets, and any climate-related assumptions relevant to impairment assessments, asset lives, capital expenditure, financing, going concern and other financial statement judgements. Climate-related matters are escalated to the Company Board where they are considered material to the holding company, the consolidated group or the financial statements, or where they require Board-level judgement or approval.

Area

Area

Description

Governance

The Company does not maintain a dedicated sustainability committee or receive routine operational climate reporting at holding company level. Oversight and management of operational climate-related matters sit with the operating group boards, committees and executive teams. The Company Board exercises oversight through the annual report approval process and by considering climate information where relevant to investment, financing, impairment, going concern, capital allocation and other matters requiring Board judgement. No director has been allocated separate day-to-day responsibility for managing climate-related risks and opportunities at holding company level, reflecting that such matters arise and are managed within the operating groups.

Risk management

Climate-related risks are identified, assessed, monitored and managed within each operating group’s enterprise risk management framework. The output of those processes informs operating group strategy, financial planning and disclosures.

Remuneration

There are no employees or executive remuneration arrangements at the Company level. Any linkage between climate-related performance and remuneration is determined at operating group level, where applicable.

Strategy and climate resilience

The Company’s business model is to hold investments in independently governed operating groups. It does not set a standalone consolidated climate transition plan or operational climate strategy, because climate-related strategy, scenario analysis and resilience assessments are performed by the operating groups, where the relevant assets, operations, customers, regulatory frameworks, geographies and management responses reside. Management has therefore considered the operating group scenario analysis and resilience assessments when assessing the resilience of the Company’s consolidated business model and strategy. Separate holding company-level scenario analysis has not been prepared because management considers that it would not provide additional information necessary for an understanding of the Company’s business, given that climate-related risks and opportunities arise through the underlying operating groups rather than through standalone holding company activities.

The operating groups considered scenarios relevant to their respective activities, including scenarios reflecting a faster transition to a lower-carbon economy, a more gradual or delayed transition, and increased exposure to acute and chronic physical climate risks. The assumptions considered included changes in energy demand, decarbonisation policy, carbon pricing and emissions regulation, customer behaviour, electrification, technology adoption, renewable and low-emissions gas development, asset utilisation, physical asset resilience, weather patterns, capital expenditure requirements and the recoverability of climate-related investment through regulatory or contractual mechanisms. Management reviewed the outputs of these assessments to identify whether climate-related risks or opportunities could materially affect the Company’s consolidated strategy, business model, financial position or financial statements, including through asset lives, impairment assumptions, forecast cash flows, regulatory recoverability, financing assumptions, going concern or the valuation of investments. On this basis, the Directors consider that the consolidated business model and strategy remain resilient across the short, medium and long term, reflecting the diversified nature of the operating groups, the regulated or contracted characteristics of significant parts of the portfolio, established operating group risk management processes, and the opportunities associated with decarbonisation, electrification, renewable energy and low-emissions energy solutions. The principal climate-related risks and opportunities are summarised below.

Mitigation includes investment in network integrity and resilience, consideration of renewable and carbon-neutral gas pathways, management of Safeguard Mechanism obligations, use of offsets where required for compliance, and assessment of capital expenditure and asset lives through regulatory and financial planning.

UE

Acute and chronic physical risks from adverse weather, including heat, flood, bushfire and wind, which can affect reliability, restoration costs and customer outcomes. Long-term risk arises if climate projections are not incorporated into network planning.

Customer electrification, network capacity investment, grid flexibility, resilience investment and strengthening of network performance in support of energy transition.

UE incorporates climate resilience and electrification requirements into network planning and regulatory submissions. Mitigating actions include reliability and resilience investment, vegetation management, emergency response planning, consideration of climate projections in asset management, initiatives to reduce operational emissions, and assessment of future offset or abatement options where residual emissions cannot be eliminated.

EDL

Transition risks from changes in green credit schemes, policy incentives, customer demand and reputation. Physical risks from temperature extremes, rainfall patterns, bushfires/wildfires and storms affecting selected sites and supply chains.

Revenue growth from green credits, landfill gas, renewable natural gas, anaerobic digestion, renewable energy, hybrid remote energy solutions and increased demand for low-emissions energy.

Sales revenue, green credit revenue and assets, property plant and equipment, operating costs, finance costs, inventories/credits, capital expenditure and cash flows.

EDL’s strategy is influenced by demand for lower-emissions distributed energy and green credit and renewable fuel markets. Mitigation includes maintaining a diversified portfolio of landfill gas, renewable natural gas, anaerobic digestion, renewables and remote energy assets, monitoring changes in credit schemes and policy settings, embedding physical climate risk considerations into site-level operations, and prioritising offsets only as a final recourse for hard-to-abate emissions.

PEGL

The key climate-related risks relate to the potential for asset stranding or reduced utilisation if the gas network is not supported as part of Northern Ireland’s long-term net zero pathway. These risks are compounded by uncertainty around biomethane, hydrogen and other green gas solutions, and by physical risks from extreme weather that could affect network resilience and continuity of supply.

The principal opportunities arise from the development of a biomethane and green gas transition pathway that uses existing network infrastructure. There are also opportunities to support low-carbon heating, hybrid heat pump services, transport and agricultural decarbonisation solutions, alongside targeted resilience investment.

PEGL considers the role of its gas distribution network in Northern Ireland’s decarbonisation pathway, including biomethane, green gas and hybrid heating solutions. Mitigating actions include continued operational emissions reduction, energy efficiency measures, waste reduction, targeted resilience investment, monitoring of policy and technology developments, and assessment of asset lives and recoverability as transition pathways become clearer.

UKREG

The principal risks relate to power price volatility, physical risks from extreme weather, asset maturation, geopolitical exposure and regulatory change. Increased renewable generation may place downward pressure on forecast power prices, while extreme weather could affect turbine performance, site infrastructure and transmission systems. Ageing assets may increase operational risk and exposure to market-based revenues as subsidies mature.

Opportunities arise from the transition to a low-carbon energy system and UK Government support for renewable generation. The portfolio provides opportunities to assess repowering, life extension and hybrid sites, including battery storage or solar generation. Newer renewable technologies, including storage and green hydrogen, may create additional revenue streams and improve grid flexibility.

Power price forecasts, generation assumptions, asset availability, useful economic lives, operating costs, discount rates, impairment assessments, carrying value of property, plant and equipment, provisions, maintenance expenditure, insurance recoverability, capital expenditure plans and future cash flow forecasts.

UKREG’s strategic response is to optimise the existing renewables portfolio while evaluating life extension, repowering and co-location opportunities where commercially and technically viable. Mitigating actions include active asset management, preventative maintenance, insurance arrangements, monitoring of power price and regulatory developments, assessment of storage or hybrid site opportunities, and continued consideration of climate-related assumptions in impairment, asset life and cash flow assessments.

Accordingly, the Group’s material climate‑related risks and opportunities include those identified within the operating groups, which (by category) include:

Climate-related transition risks — including policy/legal, market, technology and reputational risks relevant to regulated energy networks, energy generation and broader energy transition dynamics.

Climate-related physical risks — including acute and chronic weather‑related impacts relevant to infrastructure resilience, safety, reliability, and, in some cases, insurance and supply chain disruption.

Climate-related opportunities — including opportunities associated with energy transition investment, system resilience, decarbonisation solutions and related products/services within the operating groups.

While the specific financial effects of climate‑related risks and opportunities differ across the operating groups due to differing business models, regulatory frameworks and geographies, the Group expects that these matters will most directly influence the consolidated financial statements through:

Detailed descriptions of the nature, timing and magnitude of these current and anticipated financial effects are disclosed in the sustainability reports of the operating groups, with the principal risks and opportunities noted below:

Risk / Opportunity description

Adaption or Mitigation efforts

AGIH

Climate-related transition risk: Renewable and carbon-neutral gas policy.

Time horizon: medium-to-long term.

The risk relates to declining future gas demand as Commonwealth and State Governments focus on renewable electricity to deliver emissions targets.

Despite steady connection growth historically, distribution network risks include declining gas use per connection driven by behavioural change, appliance switching and warmer climates. In addition, the Victorian Government has announced a ban on new household and most new commercial building connections and end-of-life gas hot water appliance replacement from 2027 onwards, with several exemptions.

Our transmission infrastructure risk is assessed to be low in the short term (to 2030) due to length of time to develop alternative energy required for hard-to-abate and industrial customers as well as the requirement for gas fired power generation to be available for standard and peak periods, as coal fired generators are phased out and renewable power technologies require back up for 24/7 reliable power generation.

As Government policies are often state based, adverse policies will not necessarily impact all of AGIH’s assets which are spread across Western Australia, Northern Territory and Victoria. AGIH also has diversified operations of distribution and transmission which can protect against specific behavioural and policy trends.

AGIH advocate for enhanced policy certainty and investor confidence in the role of renewable and carbon-neutral gas to support our diverse customer base, enabling customer choice on their preferred pathway to reach net zero.

Through submissions to various government-led processes as well as more general stakeholder engagement, we highlight the diversity of customer needs and how existing gas infrastructure can be used to meet carbon reduction goals including through the transport of renewable and carbon-neutral gas. AGIH submissions emphasise the need for policy frameworks that facilitate this future, facilitating customer choice.

Key recent Australian Government measures include the Future Made in Australia policy2 and related Federal Budget3 items as well as the 2024 Future Gas Strategy4 which reaffirmed the necessity of natural gas in Australia’s energy mix through 2050 and beyond, albeit with an evolving role including renewable and carbon-neutral gases and the integration of CCS technologies to reduce emissions.

The Victorian Government’s Gas Substitution Roadmap Update (2024) also recognises the need to secure natural gas supplies whilst scaling up renewable and carbon-neutral gas.

Risk / Opportunity description

Adaption or Mitigation efforts

Climate-related transition opportunity: Natural gas replacement including hydrogen and biomethane for gas distribution infrastructure.

Time horizon: medium-to-long term.

Renewable and carbon-neutral gas production would increase to meet increasing demand, delivered via existing gas infrastructure.

The opportunity is for increased revenue from new projects associated with sales of renewable and carbon-neutral gas or related products.

AGIH advocates for enhanced policy certainty and investor confidence in the role of renewable and carbon-neutral gas to support our diverse customer base, enabling customer choice on their preferred pathway to reach net zero.

Renewable and carbon-neutral gases, including biomethane and renewable hydrogen have been formally recognised under the NGER Act as a decarbonisation benefit. This may result in more demand from customers for renewable and carbon-neutral gas to mitigate emissions.

The Australian Government’s 2024 Future Gas Strategy sets out that under all credible net zero scenarios, natural gas is needed through to 2050 and beyond. It also sets out as a guiding principle that “Householders will continue to have a choice over how their energy needs are met”. In addition to this the ECMC are looking to set a renewable and carbon-neutral gas target for all States and Territories. Victoria is engaging on a Renewable and carbon-neutral gas Target.

We are investing in projects that demonstrate the pathways to a low carbon future. This includes preparing new and existing assets for future fuel and carbon transport and storage.

We are also working closely with existing and emerging gas suppliers, including those providing hydrogen and biomethane at scale, to deliver these options to customers via our networks. By connecting with these suppliers, we aim to integrate renewable and carbon-neutral gases seamlessly into our infrastructure, ensuring that customers have access to cleaner energy choices.

Additional information on these projects can be found at the Metrics and Targets section.

AGIH

Climate-related physical risk: Physical resilience of gas infrastructure assets.

Time horizon: medium-to-long term.

The majority of AGIH gas infrastructure is buried underground, protecting it against the physical impact of extreme weather.

The opportunity is for the gas we transport to be seen as reliable, and a valued energy alternative under circumstances where electricity supply is interrupted, increasing demand for our services.

There is also an opportunity for increased gas delivery along the Dampier Bunbury Pipeline to supply gas peaking generation to support increased intermittent renewable electricity generation.

Climate scenario analysis illustrated the resilience of our assets to the physical impact of extreme weather, primarily based on the inherent protection of the majority of our assets being located underground.

This resilience enables us to continue to provide reliable energy as needed, safely to our customers, even under future extreme climate scenarios.

EDL

Climate-related transition risk: Changing government regulations, incentives and penalties related to decarbonization.

Time horizon: short-term

Various green credit schemes and methodologies will be under review in the coming years presenting a risk to the Group if Governments decide to wind back or amend existing schemes or methodologies, which may negatively influence revenue drivers such as per unit pricing and eligibility.

Green credit revenue ($137M) represented ~19% of the Group’s total sales revenue in the reporting year and green credits on hand were valued at $99M at 31 December 2025; the Group forecasts continued growth and earnings from green credits in the short term. A decline in the market value and/or volume of green credits produced by the Group could negatively impact the Group’s financial performance, however, the timing and extent of this impact is highly uncertain given the mitigation measures, external influences and key uncertainties described above. It is also unlikely that this risk will simultaneously manifest under all methods, schemes and jurisdictions. Furthermore, commercial mechanisms are available to the Group to partially offset or recover potential losses.

• Active engagement with government stakeholders to extend existing methods and schemes, to optimise the value and quantity of green credits produced.

• Commercial mechanisms to recover potential green revenue losses.

• Diverse portfolio of energy generation assets and products, with options to offset revenue losses through other business activities.

PEGL

Climate-related transition risk and opportunity: long-term net zero policies.

Time horizon: medium-to-long term

PEGL 's gas distribution network may not form part of Northern Ireland’s long-term net zero solution, potentially resulting in premature asset stranding and constrained investment opportunities due to absence of clear government policy supporting the gas network's role in achieving net zero.

Establish a progressive biomethane transition pathway as a cost-effective alternative to electrification of heat, securing the network's role in Northern Ireland's net zero future whilst leveraging existing infrastructure.

Additionally, deliver immediate carbon reductions (up to 50%) by connecting oil heating customers to the gas network.

PEGL actively engages with government and the Utility Regulator to influence policy frameworks and secure regulatory support for green gas investment.

Detailed technical feasibility assessments of network biomethane readiness are being conducted (including the recently completed Network Constraints project), alongside the development of commercial partnerships with biomethane producers.

Network expansion continues to connect oil heating customers whilst building the foundation for future biomethane transition.

Climate-related physical risk: extreme weather events.

Time horizon: medium-to-long term.

Increased risk to turbines and other infrastructure assets causing physical damage to on-site infrastructure and transmission systems, as well as the safety of employees and suppliers.

UKREG manage a diversified geographical portfolio, which reduces the potential impact of localised extreme weather events leading to physical damage or downtime at specific locations. There is also comprehensive insurance in place to mitigate against such risks.

UKREG is looking to invest in other renewable infrastructure assets, for example solar, that will diversify the portfolio to weather events that impact a specific type of generation.

UE

Climate-related physical risk: extreme weather events.

Time horizon: medium-term

Climate change is expected to increase the frequency and severity of extreme weather events such as heatwaves, flooding, extreme wind and bushfires which may disrupt electricity supply and increase restoration costs for the Group. These disruptions can affect customer satisfaction, regulatory compliance and financial performance.Prolonged outages may trigger Guaranteed Service Level (GSL) penalties and compensation obligations, while emergency response and fault restoration costs are likely to rise.

Reliability performance incentives under regulatory frameworks could also be adversely impacted. Furthermore, these events may require increased investment in network resilience and emergency preparedness to maintain service standards. In addition, widespread service disruptions can create negative public sentiment and may lead to interventionist policies from regulators and government.

The Group has implemented a range of measures to reduce the likelihood and impact of supply disruptions caused by adverse weather events. These measures include compliance with the Electric Line Clearance Management Plan, which ensures effective management of vegetation clearance and hazard tree removal to minimise the risk of faults caused by high wind gust events.

Effective asset maintenance strategies reduce asset failures during escalation events including heat waves and storms.

Effective maintenance ensures network switching devices can be utilised to sectionalise the network and restore supply to undamaged network infrastructure following major events.

Network reliability projects and initiatives identify and harden vulnerable parts of the distribution network from foreseeable major events and mitigate the consequences when they occur.

Well established fault and emergency response procedures ensure effective mobilisation of resources, assessment of damage, stakeholder management including effective coordination with emergency services and restoration of customers to minimize the consequences to the community and critical infrastructure following major events.

Improvements and adherence to design and construction standards ensure network assets are able to withstand foreseeable extreme weather conditions.

Progress against targets

AGIH

In 2025, AGIH has contributed to the reduction of Scope 1 and Scope 2 emissions by 5% when compared to the 2020 baseline, on track to reduce emissions by 30% by 2030.

When considering AGIG and third-party projects that are operational, under construction or in development, as well as potential sources of renewable and carbon-neutral gas adjacent to AGIG networks (including AGIH) renewable and carbon-neutral gas production able to meet this 10% (by volume) target is evident.

The Group acknowledges that to meet this target, supportive policy is required to be in place in 2026, and construction of new projects must commence no later than 2027.

In respect of supportive policy and regulatory enablers, the Group notes the following key activities during 2025:

• The Clean Energy Regulator launched the Guarantee of Origin certification framework for hydrogen from electrolysis with the scheme to be expanded to biomethane in the future.

• The Commonwealth Government established the Hydrogen Production Tax Incentive through the Future Made in Australia (Production Tax Credits and Other Measures) Act 2025.

• The Energy and Climate Change Ministerial Council committed to exploring a nationally consistent approach to renewable gas targets with consultation expected to occur in 2026.

• Following consultation in late 2024, the Victorian Government reaffirmed its commitment to establishing a Renewable Gas Target.

Targeting 100% renewable and carbon-neutral gas in the distribution networks by 2050 is at an early stage of delivery. Work in delivering the interim target of 10% renewable and carbon-neutral gas in the distribution network by 2030 is a key enabler of this target. This target was developed in line with our Net Zero Ambition to reduce the carbon intensity of the gas transported by replacing natural gas with renewable gas.

The target aligns with the net zero commitments of the states and territories in which AGIH operate, and it acknowledges that supportive policy and legislation will be critical to enable the new production projects required for delivery.

AGIH has two Safeguard Facilities, the Victorian gas distribution network and the Western Australian transmission pipeline.

Whilst safeguard emissions related to the AGIH gas distribution network decreased by 4% for the 2025 reporting year (1 July 2024 to 30 June 2025) compared to the 2024 reporting year, they were above the Safeguard Baseline.

The Group will purchase carbon offsets to clear the over baseline position by March 2026 to comply to legislation.

The AGIH transmission business has committed to a Multi-Year Monitoring Plan (MYMP) that allows the netting of emissions over the five-year period from 1 July 2023 to 30 June 2027, with a view to the net actual emissions over this period being below the calculated Safeguard Baseline. The group is on track to meet the MYMP net baseline position at the end of the MYMP period.

UE

Scope 1 and Scope 2 emissions were 6,347 and 254,065 respectively. This performance reflects sustained emissions reduction initiatives across our operations, including fleet electrification, renewable electricity procurement and energy efficiency measures in network operations.

To achieve the long-term net zero 2050 target, the Group intends to purchase and participate in carbon offset trading schemes. This is due to the inherent nature of the Group operations, asset lifespans and types and limited technological options to meet reliability requirements as a lifeline utility. The Group does not currently participate in any carbon offset trading schemes; however, will likely investigate and participate in the long-term time horizon to meet this target commitment.

EDL

The voluntary targets cover the Group’s entire operations, under an equity control basis, and includes the GHG gases covered under the GHG Protocol (carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride).

The Group’s ability to meet its GHG reduction targets is subject to a number of key assumptions and external dependencies. These include, for example, the treatment of CO2 emissions from the combustion of LFG as biogenic, which results in their exclusion from Scope 1 emissions calculations. In addition, progress toward these targets depends on factors beyond the Group’s direct control, such as the availability and effectiveness of policy instruments, evolving customer requirements, and the pace of technology development and commercialisation.

In line with the GHG Protocol and Science Based Targets Initiative (SBTi), the Group regards offsets as the final recourse for hard-to-abate emissions. The Group does not anticipate using offsets towards achieving its targets in the short- to medium-term.

PEGL

Scope 1 and Scope 2 emissions total 1,442 compared to a baseline of 2,401 in 2019, being a 40% reduction in 6 years, on track to meet the 60% reduction by 2030. Energy consumed in 2025 was 7,015MWhs compared to 11,627 in 2019, being a 40% reduction in 6 years, on track to meet the 50% reduction by 2030. Waste sent to landfill was 10,020 tonnes in 2025 compared to 46,104 in 2019, being a 78% reduction in 6 years, already surpassing the target of a 75% reduction by 2030.

UKREG

Electricity generation for 2025 was 233 GWhs compared to a target of 259 GWhs. This was due to the lower wind speeds in 2025. Community benefit spend was £594k compared to a target of £590k.

(a) Recognising revenue from major business activities

(i) Distribution and Transmission Use of System revenue

Timing of recognition: Distribution and Transmission Use of System revenue represents the revenue from electricity and gas retailers for the transportation and delivery of electricity or gasthrough the distribution system to their customers. Revenue is calculated on a per energy retailer customer basis for electricity or gas consumed, time connected to the distribution network and/or demand based charges.

TheUse of Systemcontract includes one performance obligation, which is to provide distribution or haulage services. This performance obligation is satisfied when the end customer receives electricity or gas. The company promises to provide transport and deliver electricity or gasthrough the Distribution System to their customers are performance obligations that are satisfied over time as the customer is able to simultaneously consume the electricity or gas transmitted and distributed to the customer's location.

Transaction price: Rates per quantity unit and customer tariff type are approved by the Australian Energy Regulatory (AER) each year. The method utilised to recognise revenue for theUse of Systemcontract is an output method, which is based on actual volume of electricity distributed or gas transported and actual number of customers serviced each period.

(ii) Transportation revenue

Timing of recognition: Transportation revenue is brought to account when gas is transported for a shipper in accordance with the terms and conditions of the haulage contract.

The performance obligation is satisfied when the end customer injects or withdrawsgas from the pipeline. The performance obligationis satisfiedat a point intime as the obligation is satisfied when the gas haulage contract has been met.

Transaction price: Revenueiscalculated in accordance with terms and conditions of the haulage contract.

(iii) Electricity revenue

Timing of recognition: Electricity revenue generated is recognised or accrued when control of the goods is transferred to a customer.

28

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

This performance obligation is satisfied when the electricity is generated and enters the transmission or distribution network. Performance obligations are satisfied over time as the customer is able to simultaneously consume the electricity transmitted and distributed to the customer's location. Revenue is recognised at an amount that reflects the consideration expected to be received.

Transaction price: Revenue is calculated in accordance with spot price or contracted price.

29

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

(iv) Gas revenue

Timing of recognition: Gas revenue is recognised or accrued at the time of supply.



Revenue from the sale of gas is recognised over time when control of the commodity has been transferred to the customer, which generally occurs when the product is physically transferred into a pipe or other delivery mechanism. Revenue is recognised at an amount that reflects the consideration expected to be received.

Transaction price: Revenue is calculated in accordance with the spot price or contracted price.

(v) Metering revenue

Timing of recognition: Metering revenue comprises charges to cover the cost of maintaining, operating and replacing the meter. A per annum charge varies depending on the meter type installed. The Distribution Businesses promise to provide metering maintenance services to their customers are performance obligations that are satisfied over time as there is a stand-ready obligation to provide metering maintenance services on an on-going basis.

Transaction price: Metering revenue is based on a metering charge set by meter type as approved by the AER each year.

(vi) Customer contributions - cash

Timing of recognition: Customer contributions - cash represent the revenue recorded from construction of network augmentation assets where the customer was required to fund a portion of construction towards their network augmentation.



The rendering of a customer contribution service contract includes one performance obligation, which is to either maintain customer's assets or to develop an asset. This performance obligation is satisfied over time either because the customer simultaneously benefit from the maintenance services completed and the work performed enhances the customer's assets; or the new assets are highly specific for the customer and the company has the right to receive payment for all the services performed at the end of each reporting period.



The method utilised to recognise revenue for the customer contributions contract is an input method, which is based on actual labour cost and materials consumed to perform the required service during each reporting period.



Transaction price: Revenue is calculated in accordance with terms and conditions of relevant customer contracts.

(vii) Alternative Control Services revenue

Timing of recognition: Alternative Control Services (ACS) revenue relates to a set of customer specific activities, primarily on behalf of Electricity Retailers, that fall under a particular area of regulation due to their monopoly or semi-monopoly nature.



ACS activities are of short duration and are recognised either when performed over time or if the charge is based on duration of the service, such as public lighting.



Transaction price: Rates per activity are based on either a fixed fee approved by the AER or hourly labour rates approved by the AER and recovery of materials at cost.

(viii) Other revenue from contracts with customers

Timing of recognition: Other revenue from contracts with customers comprises primarily unregulated other services and activities including unregulated revenue for rental of regulated assets, recoverable works and construction and maintenance revenue.



The delivery of a construction contract includes one performance obligation, which is to develop an asset for a customer. This performance obligation is satisfied over time either because the customer simultaneously benefit from the maintenance services completed and the work performed enhances the customer's assets; or the new assets are highly specific for the customer and the company has the right to receive payment for all the services performed at the end of each reporting period.



Transaction price: Revenue is recognised in line with contracted amounts.

30

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

(ix) Green Credit revenue

Timing of recognition: Green credit revenue is recognised at the point of generation.



Transaction price: Green credit revenue is recognised at the lower of spot and net realisable value and adjusted for changes in market value when sold. Where the market is inactive or thin trades are noted, management uses best estimates based on expert advice to determine the fair value recognised at the point of generation.



Green certificates areconsidered outside the scope ofIFRS 15 Revenue.

The unsatisfied performance obligations as at 31 December 2025 are $323.0m (2024: $297.4m) and relate to other revenue from contracts with customers. The unsatisfied contracts will be recognised progressively through to 2034.

(b) Critical accounting policies, estimates and assumptions

There is a certain level of estimation involved in the measurement of the consolidated entity's revenue, which includes:

•

In relation to Distribution & Transmission Use of System revenue an estimation of the amount of electricity or gas consumed but not billed at period end; and

•

In relation to customer contributions an estimate of the stage of completion.

As the basis of estimation for distribution revenue is based on actual electricity or gas consumption and in the case of pass through revenue the actual and accrued cost incurred, the directors do not envisage significant uncertainty risk with respect to amounts recorded in relation to applying the revenue recognition accounting policies.

As the operations of the consolidated entity are primarily based in Australia, the consolidated entity's income tax expense for the period is calculated under Australian tax laws, based on the Australian Federal income tax rate adjusted by changes in deferred tax assets and liabilities attributable to temporary differences between the tax bases of assets and liabilities and their carrying amounts in the Financial Statements, and for unused tax losses.

35

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

Current tax



Current tax is calculated by reference to the amount of income taxes payable or recoverable in respect of the taxable profit or tax loss for the year. It is calculated using tax rates and tax laws that have been enacted or substantively enacted by the reporting date. Current tax for the current and prior years is recognised as a liability (or asset) to the extent that it is unpaid (or refundable).



Deferred tax



Deferred tax is accounted for using the comprehensive statement of financial position liability method in respect of temporary differences arising from differences between the carrying amount of assets and liabilities in the financial statements and the corresponding tax base of those items. In principle, deferred tax liabilities are recognised for all taxable temporary differences. Deferred tax assets are recognised to the extent that it is probable that sufficient taxable amounts will be available against which deductible temporary differences or unused tax losses and tax offsets can be utilised. However, deferred tax assets and liabilities are not recognised if the temporary differences giving rise to them arise from the initial recognition of assets and liabilities (other than as a result of a business combination) which affects neither taxable income or accounting profit. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period(s) when the asset and liability giving rise to them are realised or settled, based on the tax rates (and tax laws) that have been enacted or substantively enacted by reporting date. The measurement of deferred tax liabilities and assets reflects the tax consequences that would follow from the manner in which the consolidated entity expects, at the reporting date, to recover or settle the carrying amount of its assets and liabilities. Deferred tax assets and liabilities are offset when they relate to income taxes levied by the same taxation authority and the consolidated entity intends to settle its current tax assets and liabilities on a net basis.



Amendment to IAS 12 - The Consolidated Entity is within the scope of the Pillar Two top up tax that that has been substantively enacted in the UK for income years beginning on or after 1 January 2025. The first period for which a Pillar Two return will be required is the income year ending on 31 December 2025. The Consolidated Entity has applied the mandatory exception to recognising and disclosing information about deferred tax assets and liabilities related to Pillar Two income taxes. The Consolidated Entity is in the process of the necessary analysis in preparation for complying with the Pillar Two model rules for the income year ending on 31 December 2025. Based on preliminary analysis derived from information in respect of 31 December 2024, the Group does not expect any potential exposure to Pillar Two top up taxes.

Notes to the financial statements

31 December 2025

(a) Critical accounting judgements, estimates and assumptions

(i) Income taxes



The consolidated entity applies the criteria outlined in IAS 12 with regards to the calculation and recognition of deferred tax assets. The application of the IAS 12 criteria involves the exercise of judgement regarding the calculation of accounting and tax bases for the consolidated entity’s assets and liabilities. Furthermore, the potential reversal of temporary differences also requires the use of estimates of future profitability, availability of taxable profits on both revenue and capital account and potential future changes in accounting and tax bases.



In particular, the expectation of the availability of future taxable profits against which deferred tax assets arising in respect of revenue losses is subject to estimation and judgement.



(ii) Recovery of deferred tax assets



Deferred tax assets are recognised for deductible temporary differences only if the consolidated entity considers it is probable that future taxable amounts will be available to utilise those temporary differences and losses.



(iii) Uncertain tax matters



Management uses best estimates based on expert advice on transfer pricing and arm’s length debt under the thin capitalisation rules to estimate the uncertain tax amount.

(a) Trade and other receivables accounting policies

(i)Trade receivables

Trade receivables are primarily for electricity sold by generators, transportation services provided and network fees. The network fees are governed by a Use of System Agreement which stipulates that all payments are to be made on the tenth day after monthly invoicing.



Trade receivables are generally due for settlement within 30 days. They are presented as current assets unless collection is not expected for more than 12 months after the reporting date.

(iii) Fair value

Due to the short-term nature of the current receivables, their fair value is considered the same as their carrying value.

(iv) Impairment and risk exposure

Trade receivables and other receivables are recognised initially at the amount of consideration that is unconditional unless they contain significant financing components, when they are recognised at fair value. The consolidated entity holds the trade receivables with the objective to collect the contractual cash flows and therefore measures them subsequently at amortised cost using the effective interest method. Details about the consolidated entity's impairment policies, the consolidated entity's exposure to credit risk, foreign currency risk and interest rate risk and the calculation of the loss allowance are provided in note 33.

(b) Critical accounting judgments, estimates and assumptions

Allowance for expected credit losses

The allowance for expected credit losses assessment requires a degree of estimation and judgement. It is based on the lifetime expected credit loss, grouped based on days overdue, and makes assumptions to allocate an overall expected credit loss rate for each group. These assumptions include recent contract performance and historical collection rates.

(a) Accounting policies

(i) Green credits held for sale

Green credits held for sale are recognised at the point of generation at the lower of spot and net realisable value (NRV) where an active market exists without thin trading. Where the market is inactive or thin trades are noted, management uses best estimates based on expert advice to recognise revenue at the point of generation. Green credits that are not expected to be realised within 12 months of the reporting date are recognised as a Non-Current Asset. NRV is the estimated selling price in the ordinary course of business, less estimated costs necessary to make the sale.

(ii) Finance lease receivable

The finance lease receivable relates to contracts between the AGI Development Group (AGID) to Fortescue Metals Group (FMG) and Newmont Tanami. Management concluded these contracts contained a lease on the basis that risks and rewards were transferred, mainly due to:



• The customer has the ability to direct the operations of the asset;

• The customer has the right to control other shippers using the pipeline;

• The customer has first right of refusal for spare capacity; and

• The customer has a buy-out option.

(iii) Leases accounting policies

Leases of property, plant and equipment where the consolidated entity, as lessee, has substantially all the risks and rewards of ownership are classified as finance leases. Finance leases are capitalised at the lease's inception at the fair value of the leased property or, if lower, the present value of the minimum lease payments. The corresponding rental obligations, net of finance charges, are included in other short-term and long-term payables. Each lease payment is allocated between the liability and finance cost. The finance cost is charged to profit or loss over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. The property, plant and equipment acquired under finance leases is depreciated over the asset's useful life or over the shorter of the asset's useful life and the lease term if there is no reasonable certainty that the consolidated entity will obtain ownership at the end of the lease term.

Leases in which a significant portion of the risks and rewards of ownership are not transferred to the consolidated entity as lessee are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are charged to profit or loss on a straight-line basis over the period of the lease.

40

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

Lease income from operating leases where the consolidated entity is a lessor is recognised in income on a straight-line basis over the lease term. The respective leased assets are included in the balance sheet based on their nature.

Notes to the financial statements

31 December 2025

(a) Property, plant and equipment accounting policies

Property, plant and equipment are stated as cost less accumulated depreciation and impairment (if any).



(i) Cost

The purchase method of accounting is used for all acquisition of assets. Cost is determined as the fair value of the assets given up, or liabilities undertaken at the date of acquisition plus incidental costs directly attributable to the acquisition.



Construction work in progress is stated at cost plus attributable overheads. Cost includes all costs directly related to specific projects including materials, labour and an allocation of overhead expenses.



Additions through business combinations are valued at fair value.



(ii) Depreciation

Depreciation is provided on property, plant and equipment, including freehold buildings but excluding land and gas stock on hand. The value of land not depreciated is $227.4m (2024: $222.8m).



The contents of the pipeline (linepack) are recorded at the value of the normal operating level for linepack, at the lower of cost and net realisable value. Linepack is recorded as part of Distribution / Generation / Pipeline. The balance is not depreciated over the life of the pipeline, as the directors believe the recoverable value of linepack will exceed the historical cost at the time the pipeline is closed down.



Depreciation is calculated on a straight line basis so as to write off the net cost or other revalued amount of each asset over its useful life to its estimated residual value. The estimated useful lives, residual values and depreciation method are reviewed at the end of each reporting period. The following estimated useful lives are used in the calculation of depreciation in current and prior periods.

Freehold buildings

15 - 68 years

Plant and equipment

3 - 40 years

Distribution / Pipeline system

3 - 120 years

(iii) Impairment

Other assets, including property, plant and equipment, are tested for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised for the amount by which the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of the assets' fair value less costs of disposal and its value in use. No impairment of other assets including property, plant and equipment has been recognised during the period.



(iv) Asset sales

The net proceeds on disposal of assets are brought to account at the date when control passes to the purchaser, usually when an unconditional contract of sale is signed.

(b) Critical accounting judgements, estimates and assumptions

Estimation of useful lives of assets

The consolidated entity determines the estimated useful lives and related depreciation and amortisation charges for its property, plant and equipment and finite life intangible assets. The useful lives could change significantly as a result of technical innovations or some other event. The depreciation and amortisation charge will increase where the useful lives are less than previously estimated lives, or technically obsolete or non-strategic assets that have been abandoned or sold will be written off or written down.

At this stage, there is no anticipation of shortened useful lives of distribution assets due to climate change, as electricity and gas distributions still require the grid of networks. EDL is currently converting a number of energy generation plants in the United States to renewal sources which is taken into consideration when assessing useful lives of assets.

Notes to the financial statements

31 December 2025

(a) Intangible assets accounting policies

(i) Goodwill

Goodwill is not amortised but it is tested for impairment annually, or more frequently if events or changes in circumstances indicate that it might be impaired, and is carried at cost less accumulated impairment losses. Gains and losses on the disposal of an entity include the carrying amount of goodwill relating to the entity sold.

(ii) Software

The value of software assets are recorded at cost. Software assets are amortised on a straight line basis over the life of the asset.

(iii) Development Approvals

Development approval (DA) arises from a legal right to realise future economic benefits through development or sale and legal ability to prevent others from doing so. The value is recorded at cost. DAs are not amortised but they are tested for impairment annually, or more frequently if events or changes in circumstances indicate that they might be impaired, and are carried at cost less accumulated impairment losses. DAs were previously recognised as WIP.

(iv) Customer Contracts

Customer contracts acquired as part of a business combination are recognised separately from goodwill. Customer contracts are carried at their fair value at the date of acquisition less accumulated amortisation and impairment losses. Customer contracts are amortised on a straight line basis over the life of the asset.

(v) Amortisation methods and useful lives

Amortisation is provided on intellectual property and software. Amortisation is amortised on a straight line basis so as to write off the net cost over the periods benefits are expected to arise. Amortisation is included within expenses from ordinary activities on the statement of Profit and Loss. The amortisation periods are as follows:

Customer contract

1 - 30 years

Software

1 - 10 years

(b) Critical accounting judgements, estimates and assumptions

Determining cash generating units

A cash generating unit (CGU) is the smallest identifiable group of assets that generate cash inflows independently of the cashflows from other assets or groups of assets.



The following CGUs have been identified for impairment testing:

•

Australia Gas Infrastructure Holdings Pty Ltd and its controlled entities (AGIH), including Dampier Bunbury Natural Gas Pipeline Trust and its controlled entities (DBP) and Multinet Gas Holdings Pty Limited (MG)

•

Energy Developments Pty Limited and its controlled entities (EDL)

•

United Energy Distribution Holdings Limited and its controlled entities (UE)

•

CKW Energy UK and its controlled entities

•

Each of the individual wind farms controlled by UK Renewables Energy Group *

•

N-Gen Energy Solutions and its controlled entities

* In relation to UK Renewables Energy Group Limited, impairment testing of intangible assets, property plant and equipment and right of use assets, the Group treats each wind farm as a separate CGU. Generation revenue is allocated to the wind farm that has generated the relevant electricity, direct costs related to the operation, maintenance and connectivity is allocated on a wind farm basis.



Goodwill generated from the acquisition is allocated to the group of CGUs at an operating segment level as shown in the table above as it represents the lowest level at which goodwill is monitored by management.

Goodwill includes amounts denominated in currencies other than AUD and is therefore subject to revaluation resulting in the above change.



No goodwill is recognised in N-GEN Energy Solutions Limited.

Critical estimates

The basis on which these cash-generating units' recoverable amounts have been determined is their fair value less costs of disposal. A discounted cash flow analysis has been used to determine fair value less costs of disposal. The key assumptions on which management have based their assessment of future cash-flows and the approach to determining values for each were:

Management monitors risks on an ongoing basis including recent market transactions for changes in Regulatory Asset Base (RAB) multiples or other changes in assumptions that may impact future cash flows or discount rates.

Cash flows are based on the CGUs business plans and range from 5 to 10 years for regulated businesses and up to26 years for unregulated businesses. Regulated revenues and expenditures for the regulated businesses are primarily based on the Australian Energy Regulator's approved regulatory determinations plus a forecast on the current business plan for subsequent years. Non-regulated revenue and expenditure were based on management's best estimates with reference to historic performance.

Theperpetual growth is estimated based on the long-term inflationary target of each region of operation and weighted based on net present value.

Notes to the financial statements

31 December 2025

The consolidated entity continues to develop its assessment of the impact that climate change may have on the amounts recognised in the financial statements. The natural environment in which the consolidated entity operates is continually changing and being monitored by management.



We have considered the impact of the climate change related risks on the value of goodwill held. The risks are long term in nature, and whilst they will provide a need for investment in the future, we conclude that there is no material impact on the carrying amount of goodwill at the date of these financial statements, nor do they lead to any additional key sources of estimation or judgment.



Management are continuously monitoring the impact of climate change on all businesses within the group. Short term actions to meet our response to climate change are within our estimated cashflows for the regulatory cycles which have been used for our impairment review. Whilst the long term impact of climate change results in uncertainty around future cash flows of the business and financial assumptions, such as discount rate, the valuation at the balance sheet date is supported by current industry performance.

Reasonably possible changes in key assumptions

Discount rate



The discount rate has been identified as a key assumption for all CGU’s. For AGIH, an increase in discount rate of 1.0% would result in breakeven in the impairment assessment. For EDL, an increase in the discount rate of 0.9% would result in breakeven in the impairment assessment.



Terminal value assumption



The RAB multiple used in the terminal value calculation has been identified as a key assumption for the UED and AGIH regulated business CGU’s. This assumption is based on an assessment of recent transaction multiples. If there were a change in the market that resulted in a decrease in the observable transaction multiples of 0.25x for UE, 1.2x for AGIH and 0.28x for PEGL, this is likely to result in impairment of these CGU’s.



No other reasonable possible changes in key assumptions would result in impairment for any of the CGUs.

Defined benefit superannuation plans - APA Group



The APA Group Superannuation Plan is a sub-fund within the MLC Superannuation Fund. The MLC Superannuation Fund is a regulated fund under the Superannuation Industry (Supervision) Act.



The defined benefit section of the Plan consists of defined benefit and defined contribution liabilities. The defined benefits are lump sum benefits calculated on years of service and final average salary. The defined benefit section of the Plan is closed to new members. The defined contribution section of the Plan is open to new members and receive accumulation benefits only.



The Plan benefit design means that the risks most commonly affecting the reported financial results are expected to be:

- Investment risk (strong investment returns tending to improve the balance sheet position, whilst poor or negative investment returns tending to weaken the position)

- Interest rate risk (the defined benefit obligation calculated under AASB 119 uses a discount rate based on bond yields. If bond yields fall, the defined benefit obligation will tend to increase);

- Salary inflation risk (higher than expected increases in salary will increase the defined benefit obligation); and

- Price inflation risk (higher than expected increases in price inflation will increase the defined benefit obligation in respect of Pension benefits).

Defined benefit superannuation plans - UE & Multinet Pty Ltd





UE & Multinet Pty Ltd (entity within the consolidated entity) operates a defined benefit superannuation plan for qualifying employees within the UE and MG businesses. Under the plan, the employees are entitled to retirement benefits based on their final salary at the time of retirement or resignation. No other post-retirement benefits are provided to these employees.



The defined benefit superannuation plan is a funded plan. The Equipsuper Contribution and Funding Policy provides for a review of the financial position of the Plan each six months, as at 30 June and 31 December, with the employer contribution rate comprising a long term contribution rate and an adjustment to meet the financing objective of a Funding Ratio of 105%.



The Funding Ratio is the ratio of assets to accrued liabilities, being the greater of vested benefits and the present value of past membership benefits. Where the Funding Ratio is greater than 100% the primary financing objective is to achieve 105% over five years. Where the Funding Ratio is less than 100% the primary financing objective is to achieve 100% over three years and 105% over five years.

The defined benefit superannuation plans are funded plans. The Equipsuper Contribution and Funding Policy provides for a review of the financial position of the Plans each six months, as at 30 June and 31 December, with the company contribution rate comprising a long term contribution rate and an adjustment to meet the financing objective of a funding ratio of 105%.

The following sets out details in respect of the defined benefit section only. The expense recognised in relation to the defined contribution plan is disclosed in note .

The funding ratio is the ratio of assets to accrued liabilities, being the greater of vested benefits and the present value of past membership benefits. Where the funding ratio is greater than 100% the primary financing objective is to achieve 105% over five years. Where the funding ratio is less than 100% the primary financing objective is to achieve 100% over three years and 105% over five years.

In the most recent review of the financial position as at 31 December 2025 the actuary recommended the employing entities contribute at a nil rate of defined benefit members’ salaries. The next review of the financial position and employer contribution rate is due as at 30 June 2026, to be completed by 30 September 2026.

The Superannuation Industry (Supervision) (SIS) legislation governs the superannuation industry and provides the framework within which superannuation plans operate. The SIS regulations require an actuarial valuation to be performed for each defined benefit superannuation plan every three years or every year if the plan pays defined benefit pensions.

The Plan’s Trustee is responsible for the governance of the Plan. The Trustee has a legal obligation to act solely in the best interests of Plan beneficiaries. The Trustee has the following roles:

•

Administration of the plan and payment to the beneficiaries from plan assets when required in accordance with the plan rules;

•

Management and investment of the plan assets; and

•

Compliance with superannuation law and other applicable regulations.

The prudential regulator, the Australian Prudential Regulation Authority (APRA), licences and supervises regulated superannuation plans.

The expected return on plan assets assumption is determined by weighting the expected long-term return for each asset class by the target allocation of assets to each asset class and allowing for correlations of the investment returns between asset classes. The expected long-term returns for each asset class are determined by investment specialists based on their long term forecasts for each asset class. The returns used for each asset class are net of investment tax and investment fees. An allowance for administration expenses has been deducted from the expected return.

Risk exposure

There are a number of risks to which the Plan exposes the consolidated entity. The more significant risks relating to the defined benefits are:

53

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

•

Investment risk - the risk that investment returns will be lower than the assumed and the consolidated entity will need to increase contributions to offset this shortfall.

•

Salary growth risk - the risk that wages or salaries (on which future benefit amounts will be based) will rise more rapidly than assumed, increasing defined benefit amounts and thereby requiring additional employer contributions.

•

Legislative risk - the risk is that legislative changes could be made which increase the cost of providing the defined benefits.

•

Pension risks - the risk is firstly that pensioner mortality will be lighter than expected, resulting in pensions being paid for a longer period. Secondly, that a greater proportion of eligible members will elect to take a pension benefit, which is generally more valuable than the corresponding lump sum benefit.

•

Inflation risk - the risk that inflation is higher than anticipated, increasing pension payments, and thereby requiring additional employer contributions.

The defined benefit asset recognised in the Statements of Financial Position represents the present value of the defined benefit obligation adjusted for unrecognised past service cost, net of the fair value of plan assets.

Any asset resulting from this calculation is limited to the past service cost, plus the present value of available refunds and reductions in future contributions to the plan.

The plan assets are invested by the trustee in a pool of assets with plans providing defined benefits for other employers. The assets have a benchmark weighting to equities of 50% and therefore the plan has a significant concentration of equity market risk. However within the equity investments, the allocation both globally and across the sectors is diversified.

Critical accounting estimates and judgements

(i) Discount Rate applied to Defined Benefits

As discussed above, defined benefit plan obligations are discounted to present value. The discount rate is determined by reference to the market yield on high quality corporate bonds from observable yield curves.

(ii) Assumptions used in actuarial valuation

The consolidated entity relies on valuations performed by suitably qualified actuaries in recognising the defined benefit superannuation plan accounting. Disclosures regarding the outcomes of such valuations and the key assumptions used have been outlined above.

Trade and other payables accounting policies

(i) Trade and other payables

These amounts represent liabilities for goods and services provided to the consolidated entity prior to the end of the financialyear which are unpaid. Trade and other payables are presented as current liabilities unless payment is not due within 12 months from the reporting date. They are recognised initially at their fair value and subsequently measured at amortised cost using the effective interest method.



(ii) Accrued interest

Accrued interest is the amount of interest that has accumulated on a borrowing since the last interest payment date which is still unpaid at the end of the reporting period.

Notes to the financial statements

31 December 2025

The total cash outflow for leases in 2025 was $18,180 thousand (2024: $10,080 thousand).

(a) Accounting policies for leases

A lease liability is recognised at the commencement date of a lease and measured at amortised cost using the effective interest method. The lease liability is initially measured as the net present value of:

•

fixed payments less any lease incentives receivable;

•

variable lease payments that depend on an index or a rate; and

•

amounts expected to be paid under residual value guarantees, exercise price of a purchase option when the exercise of the option is reasonably certain to occur, and any anticipated termination penalties.

The lease payments are discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the consolidated entity's incremental borrowing rate.

A right-of-use asset is recognised at the commencement date of a lease. The right-of-use asset is measured at cost, which comprises:

•

the initial amount of the lease liability;

•

any lease payments made at or before the commencement date net of any lease incentives received;

•

any initial direct costs incurred; and

•

an estimate of costs expected to be incurred for dismantling and removing the underlying asset, and restoring the site or asset.

Right-of-use assets are depreciated on a straight-line basis over the shorter of the lease term or the estimated useful life of the asset.

The carrying amounts are remeasured if there is a change in the following:

•

future lease payments arising from a change in an index or a rate used;

•

residual guarantee;

•

lease term;

•

certainty of a purchase option and termination penalties.

When a lease liability is remeasured, an adjustment is made to the corresponding right-of use asset, or to profit or loss if the carrying amount of the right-of-use asset is fully written down.

Burrup extension pipeline

The consolidated entity entered into a lease agreement with EPIC Energy (Pilbara Pipeline) Pty Ltd to lease a portion of the Burrup Extension Pipeline (“BEP”). The lease agreement specifies an initial base rent of $1.7 million per annum (calculated as at 1 January 2008 and escalated by CPI annually on 1 January) over an initial lease term of 20 years. The fair value of the lease at the start of the lease term (18 December 2010) was determined at $22.8 million and equates to an implicit interest rate of 6.8% pa.

(b) Critical accounting judgements, estimates and assumptions

Incremental borrowing rate

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be readily determined, which is generally the case for leases in the consolidated entity, the lessee’s incremental borrowing rate is used, being the rate that the individual lessee would have to pay to borrow the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment with similar terms, security and conditions.

To determine the incremental borrowing rate, the consolidated entity:

57

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

•

where possible, uses recent third-party financing received by the individual lessee as a starting point, adjusted to reflect changes in financing conditions since third party financing was received;

•

uses a build-up approach that starts with a risk-free interest rate adjusted for credit risk for leases held by the consolidated entity, which does not have recent third party financing; and

•

makes adjustments specific to the lease, e.g. term, currency and security.

A lease liability is recognised at the commencement date of a lease. The lease liability is initially recognised at the present value of the lease payments to be made over the term of the lease, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the consolidated entity's incremental borrowing rate. Lease payments comprise of fixed payments less any lease incentives receivable, variable lease payments that depend on an index or a rate, amounts expected to be paid under residual value guarantees, exercise price of a purchase option when the exercise of the option is reasonably certain to occur, and any anticipated termination penalties. The variable lease payments that do not depend on an index or a rate are expensed in the period in which they are incurred.

Lease liabilities are measured at amortised cost using the effective interest method. The carrying amounts are remeasured if there is a change in the following: future lease payments arising from a change in an index or a rate used; residual guarantee; lease term; certainty of a purchase option and termination penalties. When a lease liability is remeasured, an adjustment is made to the corresponding right-of use asset, or to profit or loss if the carrying amount of the right-of-use asset is fully written down.

(ii) Compliance with loan covenants

CK William Australia Holdings Pty Ltd and its subsidiary entities have complied with the financial covenants of its borrowing facilities during the 2025 and 2024 reporting periods.

(iii) Risk exposures

Details of the consolidated entity’s exposure to risks arising from current and non-current borrowings are set out in note 33.

(iv) Borrowings accounting policies

Borrowings are initially recognised at fair value, net of transaction costs incurred. Borrowings are subsequently measured at amortised cost. Any difference between the proceeds (net of transaction costs) and the redemption amount is recognised in profit or loss over the period of the borrowings using the effective interest method. Fees paid on the establishment of loan facilities are recognised as transaction costs of the loan to the extent that it is probable that some or all of the facility will be drawn down. In this case, the fee is deferred until the draw down occurs.



Borrowings are classified as current liabilities unless the consolidated entity has an unconditional right to defer settlement of the liability for at least 12 months after the reporting period.

Where the facility is denominated in currencies other than AUD, these have been translated to AUD equivalent.

(a) Information about individual provisions and significant estimates

Employee benefits

The provision for employee benefits relates to the consolidated entity's liability for long service leave and annual leave. Provision has been calculated by discounting obligations to present value. The timing of the utilisation of the provision is uncertain and will occur in periods beyond balance date.

66

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

Environment provision

Provisions for future environmental remediation are recognised where sites subject to the Environment Protection Act 1970 of Victoria, are known to be contaminated and it is probable that an outflow of economic benefits will be required to remediate the site. The estimated future outflows are the best estimate of the expenditure required to remediate the sites using third party costing estimates discounted. Future remediation costs are reviewed annually and any changes in estimates are reflected the income statement.



The timing of the utilisation of the provision is expected to occur primarily after one year from balance date.

Unfavourable Contracts

Unfavourable contracts have been recognised as an acquisition adjustment of the DUET Group. These contracts have been determined based on discounted cash flows and the forecast revenue, discounted over the contract period. One contract relates to provision of pipeline capacity. The actual reservation charge per the contract is lower than forecast regulated tariffs. The provision will be utilised over the contract period of 40 years.

Unaccounted for Gas

The provision relates to the cost that is incurred to reimburse gas retailers for the loss of gas between the point that the gas enters the network and the consumption read at the meter, in excess of the allowed benchmark. The provision will be utilised over the next two years.

Site rehabilitation

The consolidated entity has provisions for removal and remediation costs that include the dismantling and demolition of infrastructure,

the removal of residual materials and the remediation of disturbed areas for the power generating facilities. Although the ultimate cost to

be incurred is uncertain, the consolidated entity’s businesses estimate their costs using current restoration standards and techniques.

Removal and remediation costs are provided for based on the net present value of the estimated future costs of removal and

remediation to be incurred in the accounting period when the obligation arises, which usually corresponds to the period when the

consolidated entity will commence remediation operations at a particular site. The costs are estimated on the basis of an estimated site

exit date, and are reviewed at each reporting period during the life of the operation to reflect known developments.



Rehabilitation of power generating facilities comprises 88 sites with final remediation expected in 2071. Other remediation activities relating to pipeline infrastructure are expected to occur by 2085.

Other

The consolidated entity is currently subject to audit by the ATO on two tax matters. The ATO had issued an amended income tax assessment notice for one matter in the previous financial year and issued an amended income tax assessment notice for the second matter in the current financial year. Management has disputed the ATO’s position and is following the ATO’s dispute resolution process in respect of both matters. Management uses best estimates based on expert advice on transfer pricing and arm’s length debt under the thin capitalisation rules to estimate the uncertain tax amount. Management has determined the amount provided for as at 31 December 2025is a reasonable estimate.

(b) Accounting policies for provisions

Provisions are recognised when the consolidated entity has a present obligation (legal or constructive) as a result of a past event, the future sacrifice of economic benefits is probable, and the amount of the provision can be measured reliably.



The amount recognised as a provision is the best estimate of the consideration required to settle the present obligation at reporting date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows.

Notes to the financial statements

(c) Critical accounting judgements, estimates and assumptions

Employee Benefits

The consolidated entity relies on valuations performed by suitably qualified actuaries in recognising the defined benefit superannuation plan accounting. Refer to note 18 for disclosure regarding the outcomes of such valuations and the key assumptions used.



Discount Rate applied to Employee Entitlements and Defined Benefits

Long term employee benefits balances and defined benefit plan obligations are discounted to present value. The discount rate is determined by reference to the market yield on high quality corporate bonds from observable yield curves.



Environment provision

The consolidated entity relies on valuations performed by Environmental Specialists to estimate the clean-up cost of EPA notices.



Site rehabilitation

Site rehabilitation liabilities are discounted to present value. The key assumptions in the estimation process are the expected exit date of the site, the cost estimate and the discount rate. These assumptions may change in response to changes in generation, operating licences or other economic conditions.

(i) Classification of derivatives

Derivatives are classified as held for trading and accounted for at fair value through profit or loss unless they are designated as hedges. They are presented as current assets or liabilities if they are expected to mature within 12 months after the end of the reporting period.



For hedged forecast transactions that result in the recognition of a non-financial asset, theconsolidated entityhas elected to include related hedging gains and losses in the initial measurement of the cost of the asset.

(ii) Accounting for load following swaps

Electricity and Gas Contracts for difference are accounted for as cash flow hedges only when they are firm commitments and not load following swaps. Non-firm commitments are not accounted for as cash flow hedges.

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

Note 33. Financial instruments

(a) Financial risk management objectives

The consolidated entity’s activities expose it to a variety of financial risks: market risk (including foreign exchange, and interest rate), credit risk, liquidity risk and commodity price risk. Our major exposure to interest rate risk and foreign currency risk arises from our long-term borrowings. We have also translation foreign currency risk associated with transactional foreign currency exposures, such as purchases made in foreign currencies.



The consolidated entity’s overall risk management strategy focuses on monitoring and managing these financial risks such that potential adverse effects on the consolidated entity’s financial performance are minimised. Financial risk management is carried out by the four operating groups' Treasury functions under policies approved by the board of directors. Written policies exist covering specific areas such as foreign exchange risk, interest rate risk, credit risk, liquidity risk, use of derivative and non-derivative financial instruments and the investment of excess liquidity.

The consolidated entity uses the following type of derivative financial instruments to hedge these risk exposures:

•

Interest rate swap contracts: the consolidated entity agrees to exchange the difference between fixed and floating interest amounts calculated on agreed notional principal amounts. Such contracts enable the consolidated entity to mitigate the risk of changing interest rates on the fair value of fixed rate debt held and the cash flow exposures of floating rate debt held.

•

Cross-currency swap contracts: the consolidated entity agrees to exchange specified principal and interest foreign currency amounts at an agreed future date at a specified exchange rate. Such contracts enable the consolidated entity to mitigate the risk of adverse movements in foreign exchange rates.

•

Foreign currency forward contracts: the consolidated entity undertakes certain transactions denominated in foreign currencies, primarily USD, from which exposure to exchange rate fluctuations arise. Such contracts enable the consolidated entity to lock in the exchange rate at the future date for the payment or receipt.

•

Fixed price electricity contracts: the consolidated entity earns income from electricity markets from which exposure to commodity pricing risk arise. Such contracts enable the consolidated entity to reduce the variability of income from certain electricity generation sites.

•

Fixed price gas contracts: the consolidated entity income from the sale of natural gas from which exposure to commodity pricing risk arise. Such contracts enable the consolidated entity to reduce the variability of income from certain gas generation sites.

Hedge accounting is a technique that enables the matching of the gains and losses on designated hedging instruments and hedged items in the same accounting period to minimise volatility in Profit or Loss. To the extent permitted byIFRS 9, we formally designate and document these financial instruments as fair value and cash flow hedges for accounting purposes. In order to qualify for hedge accounting,IFRS 9 requires that prospective hedge effectiveness testing meets all of the following criteria:

•

an economic relationship exists between the hedged item and hedging instrument;

•

the effect of credit risk does not dominate the value changes resulting from the economic relationship; and

•

the hedge ratio is the same as that resulting from amounts of hedged items and hedging instruments for risk management.

Notes to the financial statements

(b) Derivatives

Theconsolidatedentityuses derivative financial instruments for two types of hedges:

Fair value hedges

Cash flow hedges

Objective

To convert fixed interest rate borrowings to floating interest rate borrowings.

To hedge the exposure arising from variability in future interest and foreign currency cash flows arising from borrowings that bear interest at variable rates, or are denominated in foreign currency. Cash flow hedging is also used to mitigate the foreign currency exposure arising from anticipated future transactions

Recognition date

At the date the instrument is entered into.

At the date the instrument is entered into.

Measurement

Measured at fair value.

Measured at fair value.

Changes in fair value

Changes in the fair value of the hedging instrument and changes in the fair value of the hedged item that is attributable to the hedged risk (fair value hedge adjustment) are recognised in Profit or Loss.



Ineffectiveness reflects the extent to which the fair value movements do not offset and is primarily driven by movements in credit of the hedging instrument.



Fair value hedges have an economic relationship on the basis that the critical terms of the hedging instrument and hedged item (including face value, cash flows and maturity date) are aligned. The relationship between the hedged risk and the corresponding value of the hedging derivatives results in a hedge ratio of one.

Ineffectiveness is recognised in the Profit or Loss if the change in the fair value of the hedging instrument exceeds the change in fair value of the underlying hedged item for the hedged risk. The portion of fair value movement qualifying as effective movement is recognised in the cash flow hedge reserve in equity.



All cash flow hedges are in effective hedge relationships on the basis that the critical terms of the hedging instrument and hedged item are aligned (including face values, cash flows and currency). During the year, there has been no material ineffectiveness attributable to the cash flow hedges.

Fair value hedges have an economic relationship on the basis that the critical terms of the hedging instrument and hedged item (including face value, cash flows and maturity date) are aligned. The relationship between the hedged risk and the corresponding value of the hedging derivatives results in a hedge ratio of one.

For fixed rate instruments, face value represents the face value in the underlying currency converted at the spot exchange rate as at reporting date. Revaluation impacts since inception of the borrowings due to foreign exchange movements are reflected in the amortised cost balance.

(i) Fair value measurements

The consolidated entity measures and recognises the following assets and liabilities at fair value on a recurring basis:

•

Financial assets and financial liabilities at fair value through profit or loss (FVTPL); and

•

Derivative financial instruments.

Foreign currency forward contracts are measured using the discounted cash flow method. Future cash flows are estimated based on forward exchange rates (from observable forward exchange rates at the end of the reporting period) and contract forward rates, discounted at a rate that reflects the credit risk of various counterparties. These are classified as level 2 instruments.



Interest rate swaps are measured using the discounted cash flow method. Future cash flows are estimated based on forward interest rates (from observable yield curves at the end of the reporting period), discounted at a rate that reflects the credit risk of various counterparties. These are classified as level 2 instruments.

Cross-currency interest rate swaps are measured using the discounted cash flow method. Future cash flows are estimated based on forward currency rates (from observable yield curves at the end of the reporting period) and contract currency rates, discounted at a rate that reflects the credit risk of various counterparties. These are classified as level 2 instruments.



Electricity contracts for difference are measured using the discounted cash flow method. Future cash flows are estimated based on forward market prices and contract prices, discounted at a rate that reflects the credit risk of various counterparties. These are classified as level 2 instruments.

Accounting policy for fair value measurement

When an asset or liability, financial or non-financial, is measured at fair value for recognition or disclosure purposes, the fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date; and assumes that the transaction will take place either: in the principal market; or in the absence of a principal market, in the most advantageous market.



Fair value is measured using the assumptions that market participants would use when pricing the asset or liability, assuming they act in their economic best interests. Valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, are used, maximising the use of relevant observable inputs and minimising the use of unobservable inputs.

The table below provides an analysis of financial instruments that are measured subsequent to initial recognition at fair value, grouped into Levels 1 to 3 based on the degree to which fair value is observable.

•

Level 1 fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or liabilities.

•

Level 2 fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices) and applied within a valuation technique.

•

Level 3 fair value measurements are those derived from inputs that are not based on observable market data (unobservable inputs) and applied within a valuation technique.

(d) Market risk

(i) Foreign exchange risk

The consolidated entity’s activities expose it primarily to the financial risks of changes in foreign exchange rates and interest rates. The consolidated entity measures the market risk exposures using sensitivity analysis and cash flow forecasting. There has been no change from the prior year to the types of market risks the consolidated entity is exposed to or manner in which the risks are managed and measured.

Foreign exchange risk arises from recognised assets and liabilities that are denominated in a currency that is not the entity’s functional currency. The consolidated entity undertakes certain transactions denominated in foreign currencies, primarily US Dollars (USD), from which exposure to exchange rate fluctuations arise. Exchange rate exposures are managed within approved policy parameters.

The consolidated entity’s exposure to foreign currency risk (prior to hedging contracts and excluding balances of overseas entities that operate with the same functional currency as the exposure) at the reporting period, expressed in the foreign currency, was as follows:

The following table details the consolidated entity’s sensitivity to a 10% increase and decrease in the value of the Australian Dollar (AUD) against the relevant foreign currencies. The sensitivity analysis includes outstanding foreign currency denominated financial assets and liabilities (including derivatives) and adjusts their translation at period end for a 10% change in foreign exchange rates on a total portfolio basis with all other variables held constant.

(ii) Interest Rate Risk

The consolidated entity is exposed to interest rate risk as it invests and borrows funds at both fixed and floating interest rates. The risks are managed by maintaining an appropriate mix between fixed and floating rate borrowings and through the use of interest rate swap contracts. Hedging activities are evaluated regularly to confirm alignment with the debt and liquidity management policy and ensure that the consolidated entity is not exposed to excess risk from interest rate volatility.

The sensitivity analysis contained in the table below has been determined based on the exposure to interest rates for both derivative and non-derivative instruments at the reporting date with the stipulated change taking place at the start of the financial year and held constant for the reporting period. A sensitivity of 1% (100 basis points) has been selected as this is considered reasonable given the current level of both short and long term interest rates.

*Changes in market rates under this scenario are assumed to have a nil impact on derivative hedge ineffectiveness as the consolidated entity has highly effective hedges in place.

Profit would have been affected mainly as a result of the ineffective portion of cash flow and fair value hedge transactions and floating rate financial assets and liabilities that are not in a cash flow hedge relationship. Equity, through the cash flow hedge reserve, would have been affected mainly as a result of an increase/decrease in the fair value of interest rate swaps which qualify for cash flow hedge accounting.

(iii) Commodity Price Risk

Green Credits

As at 31 December 2025, the consolidated entity held $98.7 million green credits for sale (2024: $96.3 million). The consolidated entity has a policy of entering into forward sales contracts for a proportion of green credits to manage its exposure to price risk on its green credit holdings.

Electricity Prices

The consolidated entity entered into fixed price electricity contracts to reduce the volatility attributable to price fluctuations of electricity. These contracts are for 100% of the electricity generated at certain sites for periods ranging from 1 to 3 years. Hedging the price volatility of electricity is in accordance with the operating entities risk management strategy.

As at 31 December 2025, the fair value of these full effective hedges amounted to a net asset of $6.7 million (2024liability of $6.8 million). The change in fair value was recognised in other comprehensive income.

Gas Prices

86

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

The consolidated entity entered into a fixed price gas contract to reduce the volatility attributable to price fluctuations of gas. This contract is for approximately 50% of the gas generated at one site for 20 years. Hedging the price volatility of gas is in accordance with the operating entities risk management strategy.



As at 31 December 2025, the fair value of these full effective hedges amounted to a net liability of $8.2 million (2024: $7.9 million). The change in fair value was recognised in other comprehensive income.

(e) Credit risk



Credit risk refers to the risk that counterparty will default on its contractual obligations resulting in financial loss. Default occurs when the counterparty fails to make a contractually obligated payment to us. The consolidated entity has adopted a policy of only dealing with creditworthy counterparties and obtaining sufficient collateral where appropriate as a means of mitigating the risk of financial loss from defaults. The consolidated entity's exposure and the credit ratings of its counterparties are continuously monitored and the aggregate value of transactions contracted is spread amongst approved counterparties. Credit exposure is controlled by counterparty limits that are reviewed and approved by the risk management committee annually.

The consolidated entity has adopted a lifetime expected loss allowance in estimating expected credit losses to trade receivables through the use of a provisions matrix using fixed rates of credit loss provisioning. These provisions are considered representative across all customers of the consolidated entity based on recent sales experience, historical collection rates and forward-looking information that is available.

Generally, trade receivables are written off when there is no reasonable expectation of recovery. Indicators of this include the failure of a debtor to engage in a repayment plan, no active enforcement activity and a failure to make contractual payments for a period greater than 12 months.

Trade receivables consist of a large number of customers with ongoing credit evaluation performed on their financial condition. Where appropriate, additional collateral credit support is obtained to mitigate the risk of loss.

The consolidated entity does not have significant credit risk exposure to any single counterparty. The credit risk on liquid funds and derivative financial instruments is limited because the counterparties are banks with high credit ratings assigned by international credit rating agencies.

The carrying amount of financial assets recorded in the financial statements, net of any allowance for losses, represents the consolidated entity’s maximum exposure to credit risk without taking account of the value of any collateral obtained.

Impaired trade receivables

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

Theconsolidated entityapplies theIFRS 9 simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade receivables and contract assets.



To measure expected credit losses, trade receivables and contract assets have been grouped based on shared credit risk characteristics and the days past due. The contract assets relate to unbilled work in progress and have substantially the same risk characteristics as the trade receivables for the same types of contracts. Theconsolidated entitytherefore concluded that the expected loss rates for trade receivables are a reasonable approximation of the loss rates for the contract assets.

Indicators that there is no reasonable expectation of recovery include, amongst others, the failure of a debtor to engage in a repayment plan with the group, and a failure to make contractual payments for a period of greater than 90 days past due. Impairment losses on trade receivables and contract assets are presented as net impairment losses within operating profit. Subsequent recoveries of amounts previously written off are credited against the same line item.

1(a) Summary of acquisition by Energy Developments Pty Limited



GWE Biogas Newco 2 Ltd ("GWE")



On 31 October 2025, Bio Energy (UK) Limited acquired 100% of the ordinary shares in GWE and all entities under its control.



GWE's operating business comprises of an anaerobic digestion facility in East Yorkshire UK, with a total generating capacity of 15.5MWe. The facility includes a combined heat and power plant, the production of biomethane which is injected into a pipeline, and CO2 capturing equipment. The business was acquired with 33 employees and includes key contracts to sell electricity, gas and CO2.

1(c) Contingent Consideration

Under the Share Purchase Agreement, there are contingent consideration payments to be made upon the completion of various milestones/ performance targets. These include the practical completion of an expansion project and associated performance uplift as well as an earnout for the improved performance of CO2 equipment (including a volume and pricing component).



A probability factor of 100% has been used to determine the contingent consideration payments being made on the basis that the installation and performance improvement of the expansion project is considered largely business as usual for GWE (7th expansion for the company) and as at acquisition date, there is no indication that the expected generation uplift won't be met. The CO2 volume uplift is also expected to reach the milestone in the contract on the basis of the trending increase in performance of the equipment to date. The pricing component was met prior to acquisition date. It is noted no discounting has been applied as the payments are all within 12 months of acquisition.



The contingent consideration outcomes range from a minimum payment of $0.1m to a maximum payment of $10m.

1(d) lntercompany Loan

The Consolidated Entity provided $22.0m of funding to GWE prior to acquisition for the repayment of its debt facilities. This payment has been treated as an intercompany loan upon acquisition.

The goodwill has been determined to have an indefinite useful life and is not subject to amortisation.



(ii) Acquired receivables

The acquired receivables relate to services rendered under Operating & Maintenance Agreements and are recognised at fair value. They are expected to be collected under normal terms and conditions.



(iii) Contingent liabilities

Contingent liabilities of $1.8m have been recognised as part of the acquisition. These relate to ongoing litigations with customers.

Accounting policy for business combinations

The acquisition method of accounting is used to account for business combinations regardless of whether equity instruments or other assets are acquired.

The consideration transferred is the sum of the acquisition-date fair values of the assets transferred, equity instruments issued or liabilities incurred by the acquirer to former owners of the acquiree and the amount of any non-controlling interest in the acquiree. For each business combination, the non-controlling interest in the acquiree is measured at either fair value or at the proportionate share of the acquiree's identifiable net assets. All acquisition costs are expensed as incurred to profit or loss.

On the acquisition of a business, the consolidated entity assesses the financial assets acquired and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic conditions, the consolidated entity's operating or accounting policies and other pertinent conditions in existence at the acquisition-date.

Where the business combination is achieved in stages, the consolidated entity remeasures its previously held equity interest in the acquiree at the acquisition-date fair value and the difference between the fair value and the previous carrying amount is recognised in profit or loss.

Contingent consideration to be transferred by the acquirer is recognised at the acquisition-date fair value. Subsequent changes in the fair value of the contingent consideration classified as an asset or liability is recognised in profit or loss. Contingent consideration classified as equity is not remeasured and its subsequent settlement is accounted for within equity.

The difference between the acquisition-date fair value of assets acquired, liabilities assumed and any non-controlling interest in the acquiree and the fair value of the consideration transferred and the fair value of any pre-existing investment in the acquiree is recognised as goodwill. If the consideration transferred and the pre-existing fair value is less than the fair value of the identifiable net assets acquired, being a bargain purchase to the acquirer, the difference is recognised as a gain directly in profit or loss by the acquirer on the acquisition-date, but only after a reassessment of the identification and measurement of the net assets acquired, the non-controlling interest in the acquiree, if any, the consideration transferred and the acquirer's previously held equity interest in the acquirer.

Business combinations are initially accounted for on a provisional basis. The acquirer retrospectively adjusts the provisional amounts recognised and also recognises additional assets or liabilities during the measurement period, based on new information obtained about the facts and circumstances that existed at the acquisition-date. The measurement period ends on either the earlier of (i) 12 months from the date of the acquisition or (ii) when the acquirer receives all the information possible to determine fair value.

Provisional accounting

Both business combinations during the period are both accounted for provisionally, details of the provisional accounting are provided below:

96

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

GWE Biogas Newco 2 Ltd: The initial accounting for the business combination is provisional subject to finalisation of fair values for plant and equipment and intangibles. Therefore, the fair value of plant and equipment, intangibles and deferred tax liabilities are to be confirmed.

The Goodwill of $45.7m comprises the future economic benefits arising from other assets acquired that are not individually identified and separately recognised.

The UK businesses functional currency is the Great British Pound (GBP) and as such, the value of Goodwill recorded in the Consolidated Entity's consolidated financial statements impacted by fluctuations in the AUD/GBP exchange rates. The net exchange rate differences arising during the period resulted in a decrease of $0.83m in goodwill, resulting in goodwill of $44.9m at year end.

APT AM Holdings Pty Ltd: The initial accounting for the business combination is incomplete because under the terms of the agreement, the APA Group must provide a Final Completion Balance Sheet within 40 working days of the acquistion date, which extends beyond the reporting date. As such, the balances recognised are provisional and are expected to be finalised in the following financial year.

Whilst all reported balances may be impacted, the change is not expected to be material. The deferred tax balance will be impacted by the resetting of tax bases. The Group will retrospectively adjust these provisional amounts to reflect the final acquired balance sheet within the maximum one year measurement period.

97

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

(a) Critical accounting judgements, estimates and assumptions

As noted above, business combinations are initially accounted for on a provisional basis. The fair value of assets acquired, liabilities and contingent liabilities assumed (if any) are initially estimated by the consolidated entity taking into consideration all available information at the reporting date. Expert valuers are engaged to assist with the valuation of Plant and Equipment and Customer contracts and the values reflect the most current determination of the value of these assets.



Fair value adjustments on the finalisation of the business combination accounting is retrospective, where applicable, to the period the combination occurred and may have an impact on the assets and liabilities, depreciation and amortisation reported.



It is deemed that there are no critical judgements or estamation uncertainty for the company only.

Significant restrictions

There are no significant restrictions applied to members of the consolidated entity.

Subsidiaries accounting policies

Subsidiaries are all entities (including structured entities) over which the consolidated entity has control. The consolidated entity controls an entity when the consolidated entity is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the consolidated entity. They are deconsolidated from the date that control ceases.

The acquisition method of accounting is used to account for business combinations by the consolidated entity.

Intercompany transactions, balances and unrealised gains on transactions between consolidated entity companies are eliminated. Unrealised losses are also eliminated unless the transaction provides evidence of the impairment of the asset transferred. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the consolidated entity.



Non-controlling interests in the results and equity of subsidiaries are shown separately in the consolidated income statement, statement of comprehensive income, statement of changes in equity and balance sheet respectively.

Interests in associates and joint ventures

Investments in associates are accounted for in the consolidated financial statements using the equity method of accounting. For consolidation purposes the results of the associates are immaterial and are therefore not disclosed separately.

117

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

Note 39. Material accounting policy information

The accounting policies that are material to the consolidated entity are set out either in the respective notes or below. The accounting policies adopted are consistent with those of the previous financial year, unless otherwise stated.

Basis of preparation

The financial statements have been prepared in accordance with the requirements of the Companies Act 2006 and International Financial Reporting Standards as issued by the IASB.

The separate financial statements of the company are presented as required by the Companies Act 2006. The Company meets the definition of a qualifying entity under FRS 100 ‘Application of Financial Reporting Requirements’ issued by the FRC. Accordingly, these financial statements were prepared in accordance with Financial Reporting Standard 101 ‘Reduced Disclosure Framework’.

As permitted by FRS 101, the company has taken advantage of the disclosure exemptions available under that standard in relation to share-based payment, financial instruments, capital management, presentation of comparative information in respect of certain assets, presentation of a cash-flow statement, standards not yet effective and certain related party transactions.

Where required, equivalent disclosures are given in the consolidated financial statements.

Historical cost convention

The financial statements have been prepared under the historical cost convention, except for, where applicable, the revaluation of financial assets and liabilities at fair value through profit or loss, financial assets at fair value through other comprehensive income, certain classes of property, plant and equipment and derivative financial instruments.

Principles of consolidation

The consolidated financial statements incorporate the assets and liabilities of all subsidiaries of CK William UK Holdings Limited ('Company' or 'parent entity') as at 31 December 2025 and the results of all subsidiaries for the year then ended. CK William UK Holdings Limited and its subsidiaries together are referred to in these financial statements as the 'consolidated entity'.

Subsidiaries are all those entities over which the consolidated entity has control. The consolidated entity controls an entity when the consolidated entity is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the consolidated entity. They are de-consolidated from the date that control ceases.

Intercompany transactions, balances and unrealised gains on transactions between entities in the consolidated entity are eliminated. Unrealised losses are also eliminated unless the transaction provides evidence of the impairment of the asset transferred. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the consolidated entity.

The acquisition of subsidiaries is accounted for using the acquisition method of accounting. A change in ownership interest, without the loss of control, is accounted for as an equity transaction, where the difference between the consideration transferred and the book value of the share of the non-controlling interest acquired is recognised directly in equity attributable to the parent.

Non-controlling interest in the results and equity of subsidiaries are shown separately in the statement of profit or loss and other comprehensive income, statement of financial position and statement of changes in equity of the consolidated entity. Losses incurred by the consolidated entity are attributed to the non-controlling interest in full, even if that results in a deficit balance.

Where the consolidated entity loses control over a subsidiary, it derecognises the assets including goodwill, liabilities and non-controlling interest in the subsidiary together with any cumulative translation differences recognised in equity. The consolidated entity recognises the fair value of the consideration received and the fair value of any investment retained together with any gain or loss in profit or loss.

118

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

Interests in subsidiaries are accounted for at cost, less any impairment, in the parent entity. Dividends received from subsidiaries are recognised as other income by the parent entity and its receipt may be an indicator of an impairment of the investment.

Foreign currency translation

The financial statements are presented in Australian Dollar, which is CK William UK Holdings Limited's functional and presentation currency.

Foreign currency transactions

Foreign currency transactions are translated into Australian Dollar using the exchange rates prevailing at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at financial year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss.

Foreign operations

The assets and liabilities of foreign operations are translated into Australian Dollar using the exchange rates at the reporting date. The revenues and expenses of foreign operations are translated into Australian Dollar using the average exchange rates, which approximate the rates at the dates of the transactions, for the period. All resulting foreign exchange differences are recognised in other comprehensive income through the foreign currency reserve in equity.

The foreign currency reserve is recognised in profit or loss when the foreign operation or net investment is disposed of.

Current and non-current classification

Assets and liabilities are presented in the Statement of Financial Position based on current and non-current classification.

An asset is classified as current when:

•

it is either expected to be realised or intended to be sold or consumed in the consolidated entity's normal operating cycle;

•

it is held primarily for the purpose of trading;

•

it is expected to be realised within 12 months after the reporting period; or

•

the asset is cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least 12 months after the reporting period.

A liability is classified as current when:

•

it is either expected to be settled in the consolidated entity's normal operating cycle;

•

it is held primarily for the purpose of trading;

•

it is due to be settled within 12 months after the reporting period; or

•

there is no unconditional right to defer the settlement of the liability for at least 12 months after the reporting period.

Deferred tax assets and liabilities are always classified as non-current.

Associates

Associates are entities over which the consolidated entity has significant influence but not control or joint control. Investments in associates are accounted for using the equity method. Under the equity method, the share of the profits or losses of the associate is recognised in profit or loss and the share of the movements in equity is recognised in other comprehensive income. Investments in associates are carried in the statement of financial position at cost plus post-acquisition changes in the consolidated entity's share of net assets of the associate. Goodwill relating to the associate is included in the carrying amount of the investment and is neither amortised nor individually tested for impairment. Dividends received or receivable from associates reduce the carrying amount of the investment.

When the consolidated entity's share of losses in an associate equals or exceeds its interest in the associate, including any unsecured long-term receivables, the consolidated entity does not recognise further losses, unless it has incurred obligations or made payments on behalf of the associate.

119

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

The consolidated entity discontinues the use of the equity method upon the loss of significant influence over the associate and recognises any retained investment at its fair value. Any difference between the associate's carrying amount, fair value of the retained investment and proceeds from disposal is recognised in profit or loss.

Joint ventures

A joint venture is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the arrangement. Investments in joint ventures are accounted for using the equity method. Under the equity method, the share of the profits or losses of the joint venture is recognised in profit or loss and the share of the movements in equity is recognised in other comprehensive income. Investments in joint ventures are carried in the statement of financial position at cost plus post-acquisition changes in the consolidated entity's share of net assets of the joint venture. Goodwill relating to the joint venture is included in the carrying amount of the investment and is neither amortised nor individually tested for impairment. Income earned from joint venture entities reduce the carrying amount of the investment.

Investments and other financial assets

Investments and other financial assets, other than interests in subsidiaries or associates, are initially measured at fair value. Transaction costs are included as part of the initial measurement, except for financial assets at fair value through profit or loss. Such assets are subsequently measured at either amortised cost or fair value depending on their classification. Classification is determined based on both the business model within which such assets are held and the contractual cash flow characteristics of the financial asset unless an accounting mismatch is being avoided.

Financial assets are derecognised when the rights to receive cash flows have expired or have been transferred and the consolidated entity has transferred substantially all the risks and rewards of ownership. When there is no reasonable expectation of recovering part or all of a financial asset, its carrying value is written off.

Financial assets at amortised cost

A financial asset is measured at amortised cost only if both of the following conditions are met: (i) it is held within a business model whose objective is to hold assets in order to collect contractual cash flows; and (ii) the contractual terms of the financial asset represent contractual cash flows that are solely payments of principal and interest.

Financial assets at fair value through other comprehensive income

Financial assets at fair value through other comprehensive income include equity investments which the consolidated entity intends to hold for the foreseeable future and has irrevocably elected to classify them as such upon initial recognition.

Investments

Investments includes non-derivative financial assets with fixed or determinable payments and fixed maturities where the consolidated entity has the positive intention and ability to hold the financial asset to maturity. This category excludes financial assets that are held for an undefined period. Investments are carried at amortised cost using the effective interest rate method adjusted for any principal repayments. Gains and losses are recognised in profit or loss when the asset is derecognised or impaired.

Foreign currency transactions

All foreign currency transactions during the financial period are brought to account using the exchange rate in effect at the date of the transaction. Foreign currency monetary items at reporting date are translated using the exchange rate at that date.

Exchange rate differences are brought to account in the Statement of Profit or Loss and Other Comprehensive Income in the period in which they arise except that:



(i) exchange differences which related to assets under construction for future productive use are included in the cost of those assets where they are regarded as an adjustment to interest costs on foreign currency borrowings; and



(ii) exchange differences on transactions entered into in order to hedge certain foreign currency risks (refer note 33).

120

CK William UK Holdings Limited

Notes to the financial statements

31 December 2025

Value-Added Tax ('VAT') and other similar taxes

Revenues, expenses and assets are recognised net of the amount of associated VAT, unless the VAT incurred is not recoverable from the tax authority. In this case it is recognised as part of the cost of the acquisition of the asset or as part of the expense.

Receivables and payables are stated inclusive of the amount of VAT receivable or payable. The net amount of VAT recoverable from, or payable to, the tax authority is included in other receivables or other payables in the statement of financial position.

Cash flows are presented on a gross basis. The VAT components of cash flows arising from investing or financing activities which are recoverable from, or payable to the tax authority, are presented as operating cash flows.

Commitments and contingencies are disclosed net of the amount of VAT recoverable from, or payable to, the tax authority.

New Accounting Standards and Interpretations not yet mandatory or early adopted

Accounting Standards that have recently been issued or amended but are not yet mandatory, have not been early adopted by the consolidated entity for the annual reporting period ended 31 December 2025. The consolidated entity has not yet assessed the impact of these new or amended Accounting Standards and Interpretations.



IAS 1 - Amendments to International Accounting Standards - Non-current Liabilities with Covenants

Clarifies when liabilities should be presented as current or non-current in the statement of financial position, including the impact of covenants on that classification. The amendments may impact the classification of the Group’s financial liabilities in future periods as certain of those liabilities are subject to covenants.

Going Concern

The group's business activities, performance and position, together with its principal risks and uncertainties likely to affect its future development and performance are set out in the strategic report and above. As at 31 December 2025, the group's current liabilities exceed its current assets by $1,926 million (2024: $788 million). The directors have made enquiries and reviewed the forecasts, including sensitivity analysis, and in light of the facilities available to the group, have a reasonable expectation that the company and group have adequate resources to continue in operational existence for the foreseeable future. Accordingly, they continue to adopt the going concern basis in preparing the Annual Report and accounts.



Notwithstanding the working capital deficiency, the directors believe that the going concern assumption is appropriate and that the consolidated entity will be able to pay its debts as and when they fall due given:

•

The consolidated entity has access to $1,145 million (2024: $770 million) in unused finance facilities as at 31 December 2025;

•

The consolidated entity has forecasted to generate operating cash flows and profits in 2026;

•

The operating entities of the consolidated entity have a history of refinancing expiring debt facilities;

•

The external borrowings of $2,225 million (2024: $1,095 million) are expected to be renewed on or before their maturity date.

Note 40. Contingencies

During 2024, CK William UK Holdings Limited put in place a guarantee over the bank loan taken out by UK Renewables Energy Group Limited. At 31 December 2025, the total amount of the loan under guaranteed was £219.6m (2024 - £226.9m).

Note 41. Events after the reporting period

Subsequent to the balance sheet date, the Group repaid a total of AUD101.75 million of shareholder loan to intermediary companies. The repayments were made in accordance with the scheduled repayment profile outlined below:

These repayments represent the settlement of existing shareholder loan arrangements and do not give rise to any adjustment to the amounts recognised in the financial statements as at the reporting date. Management has assessed the repayments as a non-adjusting subsequent event.

Subsequent to 31 December 2025, the Group commenced a process to dispose of its investment in Energy Developments Pty Limited and its controlled entities ("EDL"). The directors consider this to be a non-adjusting post balance sheet event as the decision to pursue the disposal arose after the reporting date. Accordingly, no adjustments have been made to the carrying amounts of the assets and liabilities included in these financial statements. At the date of authorisation of the financial statements, the disposal process remained ongoing.

No other matter or circumstance has arisen since 31 December 2025 that has significantly affected, or may significantly affect the consolidated entity's operations, the results of those operations, or the consolidated entity's state of affairs in future financial years.

Independent auditor's report to the members of CK William UK Holdings Limited

31 December 2025

Independent auditor’s report to the members of CK William UK Holdings Limited

Report on the audit of the financial statements

Opinion

In our opinion:

We have audited the financial statements which comprise:

[Policies]

The financial reporting framework that has been applied in the preparation of the group financial statements is applicable law, United Kingdom adopted international accounting standards and IFRS Accounting Standards as issued by the IASB. The financial reporting framework that has been applied in the preparation of the parent company financial statements is applicable law and United Kingdom adopted international accounting standards and as applied in accordance with the provisions of the Companies Act 2006​​.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (‘ISAs (UK)’) and applicable law. Our responsibilities under those standards are further described in the auditor’s responsibilities for the audit of the financial statements section of our report.

We are independent of the group and the parent company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the Financial Reporting Council’s (the ‘FRC’s’) Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

In auditing the financial statements, we have concluded that the directors’ use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

Click or tap here to enter text.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the group’s and the parent company’s ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

123

CK William UK Holdings Limited

Independent auditor's report to the members of CK William UK Holdings Limited

31 December 2025

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.

Other information

The other information comprises the information included in the annual report, other than the financial statements and our auditor’s report thereon. The directors are responsible for the other information contained within the annual report.

Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon.

Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.

We have nothing to report in this regard.

Responsibilities of the directors

As explained more fully in the directors’ responsibilities statement, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the directors are responsible for assessing the group’s and the parent company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the group or the parent company or to cease operations, or have no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

A further description of our responsibilities for the audit of the financial statements is located on the FRC’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.

Extent to which the audit was considered capable of detecting irregularities, including fraud

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below.

124

CK William UK Holdings Limited

Independent auditor's report to the members of CK William UK Holdings Limited

31 December 2025

We considered the nature of the group’s industry and its control environment, and reviewed the group’s documentation of their policies and procedures relating to fraud and compliance with laws and regulations. We also enquired of management and the directors about their own identification and assessment of the risks of irregularities, including those that are specific to the group’s business sector.

We obtained an understanding of the legal and regulatory frameworks that the group operates in, and identified the key laws and regulations that:

We discussed among the audit engagement team, including component audit teams and relevant internal specialists such as tax, valuations, pensions and IT, regarding the opportunities and incentives that may exist within the organisation for fraud and how and where fraud might occur in the financial statements.

As a result of performing the above, we identified the greatest potential for fraud in the following area, and our procedures performed to address it are below:

Click or tap here to enter text.

In common with all audits under ISAs (UK), we are also required to perform specific procedures to respond to the risk of management override. In addressing the risk of fraud through management override of controls, we tested the appropriateness of journal entries and other adjustments; assessed whether the judgements made in making accounting estimates are indicative of a potential bias; and evaluated the business rationale of any significant transactions that are unusual or outside the normal course of business.

In addition to the above, our procedures to respond to the risks identified included the following:

Report on other legal and regulatory requirements

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of the audit:

125

CK William UK Holdings Limited

Independent auditor's report to the members of CK William UK Holdings Limited

31 December 2025

In the light of the knowledge and understanding of the group and of the parent company and their environment obtained in the course of the audit, we have not identified any material misstatements in the strategic report or the directors’ report.

Matters on which we are required to report by exception

Under the Companies Act 2006 we are required to report in respect of the following matters if, in our opinion:

We have nothing to report in respect of these matters.

Use of our report

This report is made solely to the company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the company’s members those matters we are required to state to them in an auditor’s report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company’s members as a body, for our audit work, for this report, or for the opinions we have formed.
