Plain-text annual report

2023 Annual ReportThe value we create If originality is the ability to do things differently, Origin was created with that in mind. We were the first energy company in Australia to span retail, power generation and upstream gas production. And, we’ve kept our eye on a low-carbon future.Since listing on the ASX in 2000, Origin has grown into a leading Australian energy company. It is a privilege to provide reliable energy to millions of homes and businesses every day and make a strong contribution to communities.We’ve come a long way, but we’ve got a long way to go. Energy generation is changing rapidly as the energy transition accelerates. And with this, the needs and preferences of our customers are changing. Our communities need our support as much as ever. We’re a company that embraces opportunities and leans into challenges. And that’s how we create value. Originality Originality in visionElise Head of Export & Infrastructure for Future Fuels“It’s in our DNA to question, innovate and optimise. It drives our pursuit to reimagine a better and more sustainable future.” Some of the key beliefs that shaped our vision in the early days remain similar today: renewables will meet an increasing share of energy needs; peaking generation is crucial to maintaining reliable supply given the variable output of renewables; and there will be a revolution in how people interact with energy, underpinned by trusted relationships with retailers.Gas has always been an important part of our business, and we believe in its continued role in the energy mix both to firm the grid and as a feedstock for industries where electrification is not a viable alternative.Origin has grown from a market capitalisation of ~$300 million in 2000 to more than $14.5 billion today and in the process established a business that, we believe, is ideally positioned for the energy transition. Originality in investmentMinh Group Manager, Broadband“What we do is less about products, and more about making energy easier and smarter – being endlessly curious, making discoveries and empowering each other to make a meaningful difference.” Key investments have shaped Origin’s business and strategic positioning. Australia Pacific LNG was established alongside ConocoPhillips, and was later joined by Sinopec, with a combined $24.5 billion investment creating a leading east coast gas producer, major LNG exporter and domestic supplier.The acquisition of Country Energy, Integral Energy, Sun Retail, Powerco and CitiPower helped create a market-leading retail business with more than 4.5 million customer accounts.In 2019, we purchased a 20 per cent stake in global energy and technology pioneer, Octopus Energy, and licensed its market-leading Kraken platform propose-built for energy retailing. This has accelerated our ambition to deliver superior customer service at lower cost and differentiate Origin.Contributing to communities and creating a lasting impact has always been important. We established the Origin Energy Foundation in 2010 to support powerful education programs aimed at breaking the cycle of disadvantage and helping young Australians reach their potential. Originality in innovationDaniel Product Development Manager“We take pride in thinking differently about how to turn emerging products into ones that will be in every customer’s home.” The world of energy is changing rapidly.We’re accelerating renewables and storage in our portfolio and have signalled our exit from coal-fired generation. We’ve cultivated a culture of innovation, combining Origin’s strengths and capabilities with great ideas from start-ups around the globe. This has helped shape the products and solutions we need to be successful in this increasingly distributed, decarbonised and digitised energy landscape.We’ve deepened our focus on technology and analytics, building Origin Loop, a virtual power plant using smart data and AI to aggregate and orchestrate thousands of distributed energy sources in homes and businesses to help balance supply and demand, and share benefits with customers. Origin Loop has scaled rapidly to 815 MW of capacity which exceeds the single largest generating unit in the national electricity market. We also continue to explore the potential of future fuels including green hydrogen and ammonia, which could play an important role in the future energy mix.Origin’s ongoing success will depend on our ability to evolve to meet the fast-changing preferences of our customers for cleaner and smarter energy solutions.

In November last year, Origin announced it had received an indicative, conditional and non-binding proposal from a consortium comprising Brookfield Asset Management and MidOcean Energy, to acquire all the issued shares in Origin by way of a scheme of arrangement. That offer was at a premium of almost 55 per cent to Origin’s share price on the prior trading day. The proposal confirmed that Origin represents a highly strategic platform and one ideally positioned to benefit from the energy transition. In March this year, Origin announced it had entered into a binding Scheme Implementation Deed with the Consortium, which implies a total consideration of $8.912 per share prior to dividend adjustments, based on an assumed AUD/USD exchange rate of 0.70.1 The proposed acquisition of Origin by the Consortium continues to progress through the necessary regulatory steps. The scheme and the Board’s recommendation is subject to an independent expert concluding the scheme is in the best interests of shareholders. The independent expert process is underway. While the timing of the shareholder vote is uncertain as it relates to the timing of regulatory approvals, Origin and the Consortium are moving expeditiously towards the target to implement the scheme by early in the 2024 calendar year. Financial performance Origin’s FY2023 financial performance reflected the strength of our business and the continued strategy. We recorded higher earnings from Energy Markets, Integrated Gas and from our 20 per cent interest in the UK-based Octopus Energy. On a statutory basis, Origin announced a profit of $1,055 million, compared to a loss of $1,429 million in the prior year. Underlying profit increased to $747 million, $340 million higher than the previous year due to improved earnings across all our operations. These earnings were partly offset by higher income tax expense associated with unfranked distributions from Australia Pacific LNG. Origin benefited from record revenues and cash dividends from Australia Pacific LNG of $1,783 million, as a result of higher commodity prices. Net of oil hedging, Origin received cash distributions of $1,489 million. This distribution contributed to a strong adjusted free cash flow position of $965 million. The Board has determined a fully franked final dividend of 20 cents per share. For the FY2023 year, shareholders will have received total dividends of 36.5 cents per share. 1 To comprise $5.78 per share and US$2.19 per share, to be reduced by any dividends paid by Origin, including the FY2023 Interim and Final Dividends and any subsequent dividends prior to the implementation of the Scheme. Refer to Origin’s ASX statement on 27 March 2023 for further details regarding the price per Origin share offered by the Consortium, www.originenergy.com.au. A message from Scott and Frank 3 Operational performance Underlying EBITDA for Energy Markets was $1,038 million, up $637 million on the prior year. Electricity profit rose as higher wholesale energy costs in previous periods were recovered in electricity tariffs, and through optimisation of the energy supply portfolio. Natural gas profit also rose, on higher sales revenue and trading benefits. Total customer accounts increased by 66,000 to 4.5 million primarily driven by growth in electricity, natural gas and broadband. The migration of customers to Kraken completed in May and stabilisation activities continue. Origin is expecting to deliver cost savings of $200 - $250 million from an FY2018 baseline, by 2025. Origin Zero doubled its share of business customers on solutions broader than electricity or natural gas, providing rooftop solar, batteries, electric vehicles and demand management. The team secured several key account wins, including a leading grocery retailer, a water utility and a data centre operator. Origin Loop, the company’s virtual power plant, more than tripled connected assets to 815 MW and is well on its way to achieve our target of 2 GW. Origin’s share of Octopus Energy (UK) Underlying EBITDA was $240 million, up from a loss of $36 million in the prior year. Octopus’ step change in earnings in FY2023 reflects an increase in customer accounts and the lag in the reset of tariffs. The acquisition of Bulb Energy added ~2.5 million customer accounts, making Octopus Energy the UK’s second-largest energy retailer, with continued growth in the licensing of Kraken to other retailers resulting in 32 million accounts contracted to be on the platform worldwide. Integrated Gas Underlying EBITDA was $1,919 million, $82 million higher than the prior year, mainly due to higher commodity prices. Persistent wet weather restricted access to well sites in the first half, contributing to a 3 per cent decline in production for the year. Improved conditions in the second half allowed more well workover and optimisation activities to occur, enabling a rebound in production in the second half. Outlook The following guidance is provided on the basis that market conditions and the regulatory environment do not materially change. Origin expects higher Energy Markets Underlying EBITDA in FY2024 of $1,300 - $1,700 million, excluding Octopus Energy. Electricity gross profit is expected to improve, reflecting higher tariffs and an increased contribution from Eraring and the peaking fleet, while natural gas gross profit is expected to moderate due to higher procurement costs as supply contracts reprice. Octopus is in a rapid growth phase and continues to invest in international growth, technology platform developments and services offerings. Origin's share of Octopus Energy EBITDA is expected to be lower with a wide range of possible outcomes reflecting stronger retail competition. Australia Pacific LNG production is expected to be 680 – 710 PJ (APLNG 100 per cent), with higher capital and operating expenditure expected, primarily due to higher power costs, increased well workover and optimisation programs. Our strategy, people and Board Over the past year, execution of Origin’s strategy has accelerated leading to increasing confidence as to our future prospects as the energy transition gathers momentum. We are rapidly building our pipeline of renewable and storage projects. We approved the first phase of a large-scale Eraring battery, acquired the Warrane prospective wind development site in the New England renewable energy zone and progressed several renewable and brownfield battery development options across the portfolio. We released our first Climate Transition Action Plan (CTAP) outlining the company’s strategy and ambition to lead the energy transition through cleaner energy and customer solutions. The CTAP includes new targets to accelerate emissions reduction across Origin and create value for shareholders, towards a long-term ambition to be net zero emissions by 2050. Our CTAP received overwhelming shareholder support of ~95 per cent at our 2022 Annual General Meeting. This year’s achievements are in no small part due to the dedication and commitment of the people who embody the culture and values of Origin every day. This past year, our safety performance improved with our Total Recordable Injury Frequency Rate (TRIFR) lowering to 3.8, compared to 4.0 at June 2022. Our employee engagement score was 7.7, placing us above the industry average, and the number of females in senior leader positions increased to 46 per cent, from 40.8 per cent in FY2022. We would like to acknowledge the service of Bruce Morgan, who retired from the Origin Board in October, after 10 years of dedicated service. Bruce has made a lasting contribution to Origin over his time as a director. We are pleased with Origin’s strong operational and financial performance this year. We remain confident that our customer base, portfolio of assets and management team position Origin advantageously as the energy transition progresses. This will allow us to capture value for shareholders and deliver benefits to our customers and communities. Thank you, and we look forward to welcoming you to the Annual General Meeting.

Origin understands the underlying fundamentals and is moving, creating and shaping what is required to support an orderly transition.” Operating and Financial Review 11 Operating and Financial Review For the full year ended 30 June 2023 This report forms part of the Directors’ Report. 1 Market Context and Outlook Market context Over the past 18 months, there has been unprecedented disruption and volatility in global and domestic energy markets. The transition to a low carbon future is bringing significant change and challenges to energy companies and consumers. Russia’s invasion of Ukraine exacerbated this volatility by restricting global energy supplies and constraining supply chains resulting in a spike in global energy costs. These global events combined with local factors including coal plant constraints due to outages and flooding which restricted coal supply to power stations, contributed to severe wholesale price spikes into the early part of FY2023. The structure of the regulated mass market tariff regime in Australia meant energy retailers were locked into customer tariffs set at prices substantially below wholesale procurement prices. As regulated tariffs adjust annually to reflect market prices, retailers suffered a period of depressed margins and significant cash flow volatility, with some smaller retailers going into administration. Regulators responded by intervening in coal and gas markets seeking to lower electricity prices for consumers. Origin’s Energy Markets' first half FY2023 earnings were adversely impacted by higher fuel costs and higher levels of energy price volatility. In the second half of FY2023, Energy Markets earnings began to recover as wholesale prices declined from their peak as coal deliveries recovered and coal costs declined following the government’s introduction of the coal price cap. During FY2023 mass market tariffs did not fully recover the wholesale cost of energy. Origin expects tariffs to more closely reflect wholesale prices in the future. At APLNG, higher global oil prices resulted in record revenue during the period. Our assets performed well during this period and our focus was to continue to reliably meet the energy needs of our domestic and offshore customers. The Australian economy experienced significant inflation during FY2023. Households faced higher interest rates and higher prices, including energy costs. Origin recognises the financial pressure some of our customers are experiencing and provided around $30 million in bill relief and pricing support to our most vulnerable customers, including holding prices flat for customers who are on the Power On program. We are targeting further support for customers in hardship in FY2024. The energy transition is both a great challenge and opportunity for society. For Australia to successfully transition to a lower carbon energy system, policy reform is required to both ensure the current emissions-intensive energy system performs reliably for as long as needed, and to encourage new investment in the cleaner energy infrastructure needed to replace it. As many of the nation’s ageing coal fired power stations approach the end of their economic and technical lives, significant investment in transmission infrastructure and firming generation is required to support reliable power supply under all future scenarios. Investors will require both a stable policy environment and adequate financial returns if they are to invest the significant capital to the build the required infrastructure. The energy transition presents many opportunities for Origin, and the company is well placed to compete and grow in this environment. Over the last year we have taken a final investment decision on a major battery as part of our plan to exit coal fired generation, and we have also expanded and matured our renewable and battery investment opportunities. As more renewable energy enters the Australian energy system to replace an ageing coal fired fleet, we see more opportunity for our gas peaking generation fleet to supply reliable power to support the variability in renewable supply. Our early-stage investments in green hydrogen are progressing and being met with strong customer interest and we believe hydrogen could play a role in the future energy mix, particularly as a substitute for gas in hard to abate sectors. Consortium proposal update In March 2023, Origin entered into a binding Scheme Implementation Deed with a consortium of investors to acquire all of the shares of the company with a consideration mix comprising $5.78 per share and US$2.19 per share (Scheme). Based on an assumed AUD/USD exchange rate of 0.70, this implies a total consideration of $8.912 per share. The total consideration payable will be reduced by any dividends paid by Origin prior to implementation of the Scheme, including the interim 16.5 cents per share fully franked dividend paid to shareholders on 24 March 2023 and the 20 cents per share final dividend determined by the Board to be paid 29 September 2023. Any reduction in the amount payable to shareholders due to the payment of dividends would reduce the Australian dollar component of the total consideration. A 4.5 cents per share per month ticking fee, accruing on a daily basis, will be added to the total consideration payable per share to shareholders if implementation of the Scheme is delayed beyond 30 November 2023. The Scheme is conditional upon the satisfaction of certain conditions, including: • Origin shareholders approving the Scheme at a meeting of shareholders (Scheme Meeting); • court and regulatory approvals including the Foreign Investment Review Board (FIRB), the Australian Competition and Consumer Commission (ACCC), the National Offshore Petroleum Titles Administrator and certain other foreign investment approvals; • the issue of an Independent Expert’s Report that concludes that the Scheme is in the best interests of Origin shareholders; and • customary other conditions, including that no material adverse change occurs prior to implementation. At this stage, shareholders do not need to take any action and Origin will continue to keep shareholders updated in accordance with its continuous disclosure obligations. 12 Annual Report 2023 2 Highlights Our purpose underpins everything we do: Getting energy right for our customers, communities and planet Getting energy right for our customers Our customers are at the heart of everything we do.

Earnings from Integrated Gas increased despite the sale of 10 per cent of APLNG during the prior period. Energy Markets’ Underlying EBITDA increased by $637 million to $1,038 million. This reflected the strong performance of our portfolio as the extreme market conditions of FY2022 eased, and the higher wholesale cost of energy flowing into customer tariffs. Our retail business performed strongly - we increased customer numbers, and recorded significant growth in our Community Energy Services business. All mass market electricity and natural gas customers have been successfully migrated to the Kraken platform. We continue to focus on growing our portfolio of renewables and our cleaner energy projects, commencing early works on the first stage of the Eraring battery and progressing other renewable and storage projects, and growing our Origin Zero business. APLNG continued to deliver strong cash flow in challenging operating conditions with the three year La Niña weather cycle restricting access to well sites during H1 FY2023, affecting production. APLNG benefited from a rebound in production in 2H FY2023 following drier weather and high global oil and LNG prices. Origin's share of Octopus Energy EBITDA increased to $240 million, reflecting an increase in customer accounts and the lag in reset of regulated tariffs in the UK retail business. The result includes a six month contribution from Bulb Energy earnings following the December 2022 acquisition, which added ~2.5 million customer accounts. See to Review of segment operations (see section 6) for further details. Adjusted Free Cash Flow was down $97 million to $965 million, driven by record cash distributions from APLNG of $1,783 million and lower cash flow from Energy Markets, with higher earnings more than offset by a higher working capital movement of $771 million reflecting a moderating working capital position following the extreme wholesale price environment of late FY2022. Origin continues to invest in growth initiatives, with $253 million spent on topping up our investment in Octopus Energy, implementation of the Kraken platform, and the Eraring battery project. The Board has determined to pay a 20.0 cent per share dividend, franked to 100% bringing total distributions for the year to 36.5 cents per share, fully franked.

This resulted in a ROCE3 of 6.7 per cent in the period, up from negative 0.3 per cent in the prior year Electricity Gross Profit increased by $366 million to $574 million, driven by higher wholesale prices flowing into business and retail customer tariffs, reflecting the recovery of higher costs associated with the current and prior periods. Fuel costs increased primarily due to higher coal procurement costs with greater volumes purchased at higher market prices during the first half of FY2023. Across the year the coal price impact was lessened by the introduction of the coal price cap implemented in December 2022. Natural Gas Gross Profit increased by $379 million to $943 million, driven by repricing of business and retail customer tariffs reflecting higher wholesale costs, partly offset by higher net JKM and oil supply costs and higher procurement costs. Portfolio strength is underpinned by fixed price4 supply contracts and transport flexibility. The JKM supply position is largely hedged through to the end of FY2024, and there is one gas supply counterparty that is subject to contract price review commencing July 2023. Electricity and Natural Gas cost to serve up $89 million, primarily driven by an increase in bad and doubtful debt expense due to higher bill sizes, cost of living pressures and slower aged debt collection. Under the current challenging market conditions with high inflation and cost of living pressure, we are committed to relieving the pricing impacts on customers where possible. We provided around $30 million in bill relief and pricing support to our most vulnerable customers, including holding prices flat for customers who are on the Power On program. Customer accounts increased by 66,000 of which our Broadband business grew by 35,000 to 96,000 customer accounts and won the 2023 Canstar Blue Best-Rated Bundled Energy and Telecommunications Provider award. Origin Loop (our in house VPP) more than tripled connected assets to 815 MW during the period. Our Origin Zero business is gaining momentum with new products, services and commercial models aimed at accelerating the decarbonisation journey for large business customers. There is now more than 200 MW of flexible large business demand enrolled in our VPP, more than 400 EVs under management through a range of E-mobility solutions and the number of large customers engaging in non-commodity products doubled to around 4 per cent during the year. Our generation fleet delivered exceptional performance, with over 98 per cent start reliability across our peaking fleet, and a forced outage at Eraring of less than 5 per cent. We made a final investment decision on the first phase of the Eraring battery, and we also acquired the 60 MW Yanco Solar Farm development in NSW and a 5 per cent equity interest in Newcastle based clean-tech company Allegro Energy, and entered an agreement to acquire around 7,500 hectare Warrane farm in the New England Renewable Energy Zone (REZ) as a prospective greenfield wind development opportunity. 2 Energy Markets segment now excludes Octopus Energy. 3 12-month average.

APLNG’s cash distributions to Origin amounted to $1,783 million. Origin's share of APLNG underlying EBITDA increased by $355 million, excluding the impact of the 10 per cent ownership change in December 2021. This was partly offset by Origin's hedging losses associated with the higher commodity prices, increasing from $189 million in FY2022 to $235 million in FY2023. APLNG production volumes decreased three per cent compared to the FY2022 reflecting the cumulative impact of the three consecutive years of La Niña weather into the first half of FY2023. Production rebounded strongly in the second half of FY2023, with drier weather allowing an increase in well workover activity and wells online. The Talinga Condabri North Pipeline ramped to full capacity in December 2022 and the Orana South Loop Line completed in April 2023, enabling field production uplift and greater operational flexibility. APLNG maintained a significant role as a key contributor to the east coast market. The average realised domestic gas price increased by 37 per cent to $8.54/GJ, primarily reflecting higher market linked short term contract prices. Average prices offered to domestic customers remained below those paid by international customers. Capital and operating expenditure5 increased by $0.7/GJ to $3.90/GJ reflecting both higher expenditure and lower production. Drier weather saw an increase in workover activity focused on reducing La Niña weather inventory backlog. Additionally, the commencement of planned multi-year upstream gas processing maintenance program and increased operated and non-operated well development activity led to higher costs. APLNG 2P (proven plus probable) reserves increased 175 PJ before production, representing a reserves replacement ratio of 26 per cent, primarily driven by non-operated 2P reserve replacement during FY2023. After production, 2P reserves decreased by 499 PJ.7 Other highlights across Integrated Gas during the period included: • Beetaloo Basin – In November 2022 Origin completed the sale of its interest in the Northern Territory’s Beetaloo Basin and received upfront consideration of $60 million and a royalty agreement covering future production. • Canning Basin – An agreement has been executed with Buru Energy Limited to exit Origin’s interest in the Canning Basin and the transaction is now expected to complete in the first half of FY2024, awaiting regulatory approval. • Cooper-Eromanga Basin – Origin executed an agreement to transfer its 75 per cent interest and operatorship of five permits back to Bridgeport, and has surrendered the remaining twelve permits in the Cooper-Eromanga Basin. • Hunter Valley Hydrogen Hub - Origin executed a $70 million grant Funding Agreement with the Commonwealth Government for the implementation of the Hunter Valley Hydrogen Hub project. 5 Opex excludes purchases, one-off write off and reflects royalties at the breakeven oil price. 6 Origin's interest is 27.5 per cent. Prior to 8 December 2021 it was 37.5 per cent. 7 Refer to Section 8 for disclosure relating to Tri-Star litigation associated with these CSG interests. Operating and Financial Review 17 3 Our strategy Our strategy During the year we made significant progress towards executing our strategy: • Progressed the transformation of our retail business with the migration of all of our mass market electricity and natural gas customer accounts to the Kraken platform • Took a final investment decision on the first stage of our Eraring battery project, committing to around $600 million of investment over the next two years. This first stage involves the construction of a 460 MW battery storage system with a dispatch duration of two hours • Grew our virtual power plant to 815 MW across 276,000 connected assets • Entered into joint venture arrangements with leading UK based renewable developer RES which applied for offshore wind feasibility licenses representing 3 GW of offshore development projects off the coast of Gippsland, Victoria • Progressed FEED for a Hunter Valley Hydrogen Hub, a green hydrogen project with a final investment decision targeted for FY2024 • Announced intention to exit our upstream exploration portfolio. We completed the sale of Beetaloo and plans to exit from the Canning and Cooper-Eromanga Basin are well advanced • Grew our broadband business by 35,000 accounts • Grew our Electric Vehicle business to more than 400 vehicles under management Our business drivers As a leading integrated energy company, Origin’s earnings drivers are spread across the energy value chain. Our electricity margin is driven by outperforming the market cost of energy through our supply portfolio (including our power stations and supply contracts). Our portfolio of coal and gas generation plants, renewable energy Power Purchase Agreements (PPAs) and market supply and hedge contracts gives us with the flexibility to manage energy procurement costs. As we sell more energy than we generate, we have the ability to build or contract renewable energy and storage. In natural gas, Origin’s wholesale margin is driven by a strong gas supply portfolio, with pipeline and storage flexibility enabling us to direct gas to where it is most needed. A large portion of supply is under long-term contracts that are either fixed-price8 or linked to oil and LNG spot prices. Some of our contracts reprice to market over time. Profitability in energy retailing is driven by managing retail margins through matching retail tariffs with energy procurement costs combined with an efficient, low cost operation, innovative products, and the ability to attract and retain customers through providing a superior customer experience. We implemented the Kraken retail system to further lower our cost base and enhance our customer experiences. We own 20 per cent of Octopus Energy9, a UK-based fast-growing energy technology company. Octopus owns the Kraken technology platform which has significant global licensing potential. Octopus is the second largest energy retailer by customer accounts in the UK. Origin is the upstream operator and has a 27.5 per cent interest in APLNG, which is Australia’s largest CSG to LNG project. It is a significant supplier to both domestic gas and international LNG markets, with the majority of volume contracted until around 2035. Profitability is underpinned by maintaining a low capital and operating cost base relative to revenues, much of which are linked to oil prices. In FY2023, around 77 per cent of APLNG gas volume was sold as LNG (of which 95 per cent was under long-term oil-linked contracts). 8 Subject to CPI adjustments. 9 Following CPPIB' investment in Octopus Energy during December 2021, Origin accounted for its interest in Octopus Energy at 18.7 per cent from 1 December 2021 (previously 20 per cent), with subsequent investment of $173 million during FY2023 to maintain its 20 per cent interest from August 2022. 19 March 20222022 Strategy PresentationOur strategic pillarsOur ambitionENABLEcustomers to decarboniseGROWour portfolio of renewables and cleaner energy REDUCE emissions of our existing operationsUnrivalled customer solutionsAccelerate renewable and cleaner energyDeliver reliable energy through the transitionOur decarbonisation prioritiesTo lead the energy transition through cleaner energy and customer solutionsOur purposeGetting energy right for our customers communities and planet 18 Annual Report 2023 Our strategic pillars We have three strategic pillars: Unrivalled customer solutions We have a leading retail business with 4.5 million customer accounts, delivering a superior customer experience at low cost and with churn lower than our Tier 1 competitors. Our strategy to increase the value of our retail business and enhance customer experience involves: • adopting a new operating model and migrating customers to the world class Kraken platform, delivering a superior customer experience, lower costs, a leaner operation and lower churn. We are targeting a $200 - 250 million cost reduction from FY2018 baseline by FY2025. As at FY2023 we have realised ~$150 million in cost savings, excluding the impact of rising bad and doubtful expenses • increasing the breadth of products offered including broadband, solar, batteries, connected solutions and E-mobility • using our strong data analytics capability to enable personalised and segmented offers and experiences for customers For our larger business customers, we are working to simplify the energy transition, providing tailored energy and decarbonisation solutions through Origin Zero. These solutions can include elements such as renewable energy, demand response, solar, batteries, energy management and EV fleet management. Through our Octopus Energy investment, we have access to an industry-leading retail platform to deliver the lowest cost and market-leading customer happiness, as well as exposure to Octopus’s global growth. Accelerate renewables and cleaner energy We will invest in cleaner energy positions to support our customers’ demand for energy and decarbonisation solutions. We will increase our renewable energy supply through new investments, partnerships, and projects, targeting multi-GW renewable growth opportunities through a staged and disciplined investment and/or contracting approach. In addition to our significant thermal peaking generation portfolio, we will invest in growing our 'firming capacity' such as batteries and our VPP to support the growth of renewables during periods of peak demand and lower renewable generation. We have developed a proprietary VPP platform to connect and use artificial intelligence to orchestrate distributed assets. We are growing our battery storage portfolio and took a final investment decision on the first stage of our battery project at Eraring. We are investigating opportunities to invest in cleaner fuels for harder-to-abate sectors, including domestic and export green hydrogen projects, targeting domestic hydrogen supply from the mid 2020s and export supply from the late 2020s. Deliver reliable energy through the transition We have a valuable portfolio of assets that play a critical role in providing customers with reliable and affordable energy as we transition to a low-carbon future. We believe gas will remain a key part of the energy mix during the transition. Through our 27.5 per cent interest in APLNG, we continue to be a low cost supplier of gas, for domestic and export customers. Our Eraring coal fired power station continues to support the reliability and security of the electricity market. We have announced the potential early retirement of Eraring as our portfolio and the market transitions to cleaner sources of energy and new sources of supply enter the market. Our existing thermal peaking generation will continue to play a critical role in providing capacity and firming as coal generators such as Eraring retire and are replaced by intermittent renewables. We have a leading domestic wholesale gas position with the ability to transport gas across the east coast to support our gas fired generation fleet as well as residential, business and wholesale customers. LPG Operating and Financial Review 19 4 Guidance The following guidance is based on current market conditions and the regulatory environment. Ongoing volatility in market conditions is likely and may adversely impact operations. Energy Markets FY2024 EBITDA is expected to be $1,300 - $1,700 million, excluding Octopus Energy. Electricity gross profit is expected to increase due to tariffs repricing reflecting higher energy procurement costs and capacity prices in recent periods, improving the contribution from Eraring and our thermal peaking fleet. Coal price caps are also expected to continue to 30 June 2024, reducing fuel costs to Eraring. Gas gross profit is expected to moderate as energy procurement costs increase from supply contracts repricing and higher JKM linked supply costs. Energy Markets’ cash flow is expected to improve compared to FY2023, driven by higher earnings and the first refund of LGC shortfall charge, partially offset by higher working capital requirements driven by higher customer tariffs. We anticipate a reduction in electricity gross profit in FY2025 as customer tariffs decline in line with wholesale costs following government intervention in late 2022. We expect to deliver on our commitment of $200 - $250 million cost reduction by FY2025, from an FY2018 baseline. Octopus Energy Octopus is in a rapid growth phase and continues to invest in international growth, technology platform developments and services offerings. Origin's share of Octopus Energy EBITDA is expected to be lower with a wide range of possible outcomes reflecting stronger retail competition. FY2024 will include a full year contribution from Bulb. Integrated Gas We estimate higher production in FY2024 of 680 - 710 PJ (APLNG 100 per cent), reflecting La Niña weather production recovery and continued cyclical upstream gas processing maintenance program. We estimate higher total APLNG capex and opex of $3.9 - $4.4/GJ, reflecting: • higher power costs; • increased workover and base production optimisation programs; and • higher non-operated development activity; partly offset by • lower cyclical maintenance. Unit capex and opex over FY2025 and FY2026 is expected to be lower at $3.6 - $4.1/GJ following delivery of production optimisation and cost of supply initiatives, completion of upstream cyclical maintenance program and expected lower power costs10. At 7 August 2023, Origin estimates that approximately 41 per cent of APLNG’s FY2024 JCC oil price exposure has been priced at US$84/bbl before hedging, based on the long-term LNG contract lags, and 23 per cent of APLNG's FY2024 JKM exposure has been priced at US$11/MMBtu. Based on forward market prices, we estimate losses in FY2024 on oil, gas and fx hedging of $27 million. We estimate a gain on LNG trading in FY2024 of $40 - $60 million, and across both FY2025 and FY2026, a gain of $450 - $650 million. This outlook remains subject to market prices on unhedged volumes, operational performance and delivery risk of physical cargoes, and shipping and regasification costs.

Corporate costs increased by $2 million, primarily reflecting higher employee costs, and IT and People and Culture projects. These were partly offset by non-repeat of ERP implementation costs and lower foreign exchange loss. Underlying D&A increased by $78 million, driven primarily by accelerated depreciation following the reassessment of Eraring's useful life. Underlying share of ITDA increased $25 million, driven by increased ITDA from Origin’s equity share of Octopus Energy ($50 million), offset by lower ITDA from APLNG ($28 million), comprising lower net interest expense ($53 million) and depreciation and amortisation ($39 million), partly offset by higher tax expense ($64 million). Underlying MRCPS interest income decreased $48 million with the principal balance fully repaid during the prior year following buy-backs by APLNG. Underlying net interest expense decreased $40 million, reflecting higher interest income due to a higher cash balance and interest income on futures collateral positions. Underlying income tax expense increased $543 million, reflecting increased earnings from Energy Markets and unfranked dividends from APLNG. 22 Annual Report 2023 5.3 Cash flows Operating cash flow Underlying EBITDA Underlying equity accounted share of EBITDA (non-cash) Other non-cash items in Underlying EBITDA Underlying EBITDA adjusted for non cash items Change in working capital Futures exchange collateral Energy Markets Integrated Gas - excluding APLNG Corporate Other Tax paid Cash flow from operating activities FY23 ($m) 3,107 (2,487) 183 803 (1,061) (290) (671) (113) 13 (182) (193) (633) FY22 ($m) 2,114 (2,097) 118 135 590 471 68 48 3 (167) (27) 531 Change ($m) Change (%) 993 (390) 65 668 (1,651) (761) (739) (161) 10 (15) (166) (1,164) 47 19 55 n/a n/a n/a n/a n/a 333 9 n/a n/a Operating cash flow includes outflows from Integrated Gas hedging activities and the tax associated with increased unfranked dividends from APLNG, however excludes those dividends received from APLNG. Distributions from APLNG are included in investing activities, and increased $188 million from FY2022. Operating cash flow decreased $1,164 million, reflecting: • Unfavourable change in working capital cash flows ($1,651 million) reflecting an outflow of ($1,061 million) in FY2023, compared with an inflow of $590 million in the prior period. Current year cash outflow driven by: – Energy Markets working capital balances increased by $671 million driven by the unwind of higher priced net creditors for wholesale energy, following the extreme wholesale price environment in FY2022. A build up of the Eraring coal stockpile occurred during H1 FY2023, however the value of inventory has moderated in H2 FY2023 due to lower coal prices, following the implementation of the coal cap in December 2022 – Integrated Gas working capital balances increased by $113 million during the period primarily reflecting the cash settlement timing of LNG trading activities; – Futures collateral outflow of $290 million reflecting cash collateral paid associated with the mark to market valuation of gas and electricity hedge contracts • Other ($182 million), which primarily reflects the cash impact of items excluded from Underlying Profit, primarily restructuring costs excluded from Underlying Profit and the 2022 LGC shortfall charge (see Appendix 2 for further details) • Increased income tax paid ($166 million) reflecting the commencement of unfranked dividends received from APLNG • Lower earnings from Integrated Gas - Other ($30 million) • Partially offset by higher earnings from Energy Markets ($637 million) Underlying equity accounted share of EBITDA (non-cash) reflects share of APLNG ($2,246 million) and share of Octopus Energy ($240 million). Other non-cash expenses include provisions for bad and doubtful debts ($148 million), share-based remuneration ($25 million) exploration expense write-off ($23 million), partly offset by change in value of derivatives ($21 million).

Capital expenditure comprises: • generation maintenance and sustaining capital ($219 million), primarily at Eraring ($147 million) due to costs associated with the Ash Dam ($69 million) and maintenance activities, as well as Darling Downs Power Station capital spares and major outage ($32 million) • other sustaining capital ($66 million) including LPG ($33 million), and CES ($12 million); • productivity/growth ($180 million) including deferred and contingent licensing payment to Octopus Energy ($20 million), other Kraken implementation costs ($33 million), Eraring battery ($27 million) for which Origin reached FID on 460MW stage 1 during the year, early stage renewable and storage development projects ($29 million), and growth in CES ($17 million) and Origin Zero ($13 million); and • exploration and appraisal spend ($11 million) primarily related to the appraisal programs in the Beetaloo and Canning Basins. Cash distributions from APLNG amounted to $1,783 million comprising unfranked dividends, up from $1,595 million in FY2022, which comprised $433 million in unfranked dividends, $1,112 million of MRCPS buy backs and $50 million in MRCPS interest. Investments include deferred and contingent consideration for the equity interest in Octopus Energy ($173 million), Climate Asset Management Nature Based Carbon fund investment ($13 million) and the acquisition of Yanco Solar Farm ($6 million). Disposals relate primarily to the divestment of Origin's interest in Beetaloo.

Upon issuance of a bank guarantee to APLNG by Origin the cash was distributed to Origin by way of a loan. Operator cash call movements represent the movement in funds held and other balances relating to Origin's role as the upstream operator of APLNG. Australian Energy Market Operator (AEMO) cash deposits relate to cash security deposits placed with AEMO to support Origin's energy purchases from national electricity and gas markets. The obligation is typically satisfied by bank guarantees; however the obligation was partially met with cash in FY2022, and subsequently refunded to Origin in FY2023 On-market purchase of shares represents the purchase of shares connected with employee share remuneration schemes as well as a share buy back in FY2022. The employee share plan terminated in March 2023 due to the proposed acquisition of Origin by the Consortium. Settlement of foreign currency contracts represents the partial closure of contracts executed in prior periods to monetise the value in certain cross-currency interest rate swap contracts. These foreign currency contracts have now been settled in full. 24 Annual Report 2023 Free Cash Flow Free Cash Flow represents cash flow available to pay dividends, repay debt, invest in major growth projects or return surplus cash to shareholders. This is prepared on the basis of equity accounting of APLNG. Specific items may be excluded from Free Cash Flow, to better represent cashflows from the underlying business. In FY2023, consistent with previous years, cash payments associated with the Octopus Energy equity investment and Kraken licence implementation costs ($226 million) , as well as initial spend on the first stage of a large-scale battery at the Eraring Power Station ($27 million) were considered to be Major Growth and were excluded from FY2023 Free Cash Flow.

At 30 June 2023, these ratios were 1.2x and 24 per cent respectively. Our long-term credit profile is Baa2 (stable) from Moody’s. 11 Gearing is Adjusted Net Debt divided by Adjusted Net Debt plus Equity. 26 Annual Report 2023 Debt maturity profile - excluding lease liabilities (A$bn) Debt portfolio management Average term to maturity decreased from 4.4 years at 30 June 2022 to 3.6 years at 30 June 2023. The average interest rate on drawn debt increased from 4.3 per cent in FY2022 to 5.0 per cent in FY2023. As at 30 June 2023, Origin held $0.4 billion12in cash and $2.8 billion in committed undrawn debt facilities. This liquidity position of $3.2 billion is held to meet near-term debt and lease liability payment obligations of $0.2 billion and to maintain a sufficient liquidity buffer. 2.5 2.0 1.5 1.0 0.5 0 FY24 FY25 FY26 FY27 FY28 FY29 FY30 FY31 FY32 FY33+ Capital Markets Debt & Term Loan Loans and Bank Guarantees - Drawn Loans and Bank Guarantees - Undrawn APLNG funding During construction of APLNG, shareholders contributed capital via ordinary equity and the investment in preference shares (termed MRCPS) issued by APLNG, with the MRCPS fully redeemed prior to the end of FY2022. Subsequent distributions from APLNG have been received via unfranked dividends. APLNG also funded construction via US$8.5 billion (APLNG 100 per cent) in project finance facilities. These facilities were partially refinanced in FY2019. The outstanding balance at 30 June 2023 was US$4,888 million (A$7,374 million), net of unamortised debt fees of US$39 million (A$59 million).

This brings Origin’s total distributions to shareholders for FY2023 to 36.5 cents per share, representing 66 per cent of Adjusted Free Cash Flow. The final dividend will be paid on 29 September to shareholders registered as at 6 September 2023. Origin will seek to deliver sustainable shareholder returns through the business cycle and will typically target a payout range of 30 per cent to 50 per cent of Adjusted Free Cash Flow per annum in the form of ordinary dividends. Adjusted Free Cash Flow is defined as cash from operating activities and investing activities (excluding major growth projects), less interest paid. Remaining cash flow will be applied to further debt reduction, value accretive organic growth and acquisition opportunities, and/or additional capital management initiatives. The dividend payout ratio of 66 percent is above the target range, reflecting the improved earnings outlook, the company's strong balance sheet and the one-off increase in working capital. The Board maintains discretion to adjust shareholder distributions for economic and business conditions. Further capital management initiatives will be considered by the Board during FY2024 and beyond, taking into account franking balances, business conditions, growth opportunities, and the status of the Brookfield/EIG transaction. 12 Excludes $93 million cash held on behalf of APLNG as upstream operator. 13 Gearing is defined as project finance debt less cash, divided by project finance debt less cash plus equity.

Unit fuel costs increased from $68.2/MWh to $87.8/ MWh. Eraring generation was higher (+1.2 TWh) with improved coal deliveries from our key coal supplier via conveyor and from suppliers via rail, as Origin seeks to diversify its coal supply chain. Coal price was higher driven by greater volumes of coal purchased at higher market prices during the first half of FY2023 as long term contractual supply contracts approach their expiration date. Across the year the coal price impact was softened by the introduction of the coal price cap implemented in December 2022; -$91 million due to higher other electricity procurement costs, largely reflecting higher net pool costs due to higher pool prices on short positions and higher generation operating costs on increased maintenance activities as well as ash dam related costs. Bundled renewable PPA costs increased due to higher Stockyard Hill volumes, partly offset by lower Solar FiT costs driven by improved value management of Solar customers, as well as lower market contract volumes purchased due to improved Eraring output; and • Volumes increased 0.4 TWh, reflecting a 0.7 TWh increase in business volumes on net customer wins, partly offset by a 0.3 TWh decrease in retail volumes due to lower household usage. With the volume increase primarily related to customers on pool price pass-through arrangements, there was no material impact to Gross Profit. 40 30 20 10 0 FY22 $m 7,125 4,148 2,977 (6,918) (3,271) (3,647) 207 2.9% $/MWh 200.8 260.6 152.1 (194.9) (92.2) (102.8) 5.8 Change (%) Change ($/MWh) 8.8 5.8 13.0 (3.8) 3.5 (10.3) 176.6 154.1 15.6 20.7 14.1 (5.4) 4.1 (9.5) 10.2 Sources and uses of electricity (TWh) FY22 Sources FY23 Sources FY22 Uses FY23 Uses Solar FiT Renewables Coal (Eraring) Gas Other Swap contracts Short position Business Retail Losses Owned and contracted generation output of 19.0 TWh, was higher by 0.3 TWh on FY2022, primarily driven by higher Eraring generation output.

Higher labour costs have been incurred in our Retail business driven by compliance, regulatory and growth activities. The migration of mass market electricity and natural gas customers to the Kraken platform was successfully completed in early May 2023. We remain committed to target a $200 - $250 million reduction in operating and capital costs from a FY2018 baseline but with delayed realisation of remaining benefits into FY2025. The business is focussed on stabilisation post migration and supporting customers through a period of cost of living pressures. Around $150 million cost savings has been achieved as at the end of FY2023 from the FY2018 baseline, excluding the impact of rising bad and doubtful expenses. Bad debt expense as a percentage of total Electricity and Natural Gas revenue increased to 1.17 from 0.59 in FY2022.

This includes our wholly-owned operations in Vanuatu, American Samoa, Samoa and Cook Islands, and joint-venture operations in Fiji, Papua New Guinea and the Solomon Islands. The sale remains subject to fulfilment of conditions precedent and regulatory approvals. The LPG business in the Pacific contributed $27 million of EBITDA in FY2023. Gross Profit was higher in FY2023 largely driven by higher retail sales across both Australian and Pacific businesses. Volumes were up 5 per cent as a result of continued growth in large commercial segment and recovery in pacific economies post COVID-19 downturn. Operating costs increased $13 million with inflationary impacts and supply challenges partly mitigated through cost optimisation initiatives and price increases. 6.1.6 Solar and Energy Services Revenue and Other Income CES Gross Profit Solar Gross Profit Other Gross Profit Gross Profit Operating costs Underlying EBITDA FY23 ($m) 564 148 23 (1) 170 (115) 55 FY22 ($m) 405 98 33 2 133 (81) 52 Change ($m) 159 50 (9) (3) 37 (35) 3 Change (%) 39 51 (29) n/a 28 43 5 Origin provides installation of solar photovoltaic (PV) systems and batteries to residential and business customers, and ongoing support and maintenance services.

The result primarily reflects an increase in customer accounts and the lag in reset of regulated tariffs in the UK retail business. Tariffs are capped by the regulator Ofgem and reflect an allowance for wholesale, network, operating and other costs. The loss in the prior year resulted from incurring higher cost of energy, with an inability to pass this onto customers due to the lag in the reset of regulated tariffs. The current year saw these costs recouped. During FY2023 there was also a change in the reset frequency from six months to quarterly, enabling more rapid response to changing wholesale market prices. This allowed higher wholesale costs in HY2023 to be recouped in the second half. The majority of Octopus' customers are priced at a discount to the Ofgem price cap. FY2023 saw a six-month contribution from the customers acquired from Bulb Energy, which added 2.5 million customer accounts in December 2022. The contribution includes accounting fair value considerations as a result of the acquisition agreement and will continue to do so for the duration of the agreement. Following the Bulb acquisition, Octopus Energy is the second largest UK energy retailer by customer accounts and is continuing to grow organically. Customer accounts in the UK retail business have grown to around 9.7 million at the end of June 2023, a 61 per cent increase in the year. Octopus' software licensing business, Kraken, has achieved a 25 per cent growth in accounts contracted to the platform. Kraken earns recurring revenue from licencing the platform to utilities as well as one-off fees earned through the period of customer account migration. Recurring revenue will grow as accounts are migrated onto the platform. Total licensing revenue is down as FY2022 included higher one-off migration and performance payments. The Kraken platform is now contracted to serve over half of all UK households, with a strong global sales pipeline, driving towards a 100 million licensed customer account ambition by 2027. All of EON’s UK customers and Origin's mass-market electricity and natural gas customer accounts have been successfully migrated to the Kraken platform. Migration has begun for EDF’s UK customers. Kraken licensing has expanded into new utilities, with the first water and broadband deals signed in July 2023. Octopus' operating costs increased, driven by investment in people to scale up growth in licensing delivery, energy installation services and international retail businesses. 16 Following CPPIB' investment in Octopus Energy during December 2021, Origin accounted for its interest in Octopus Energy at 18.7 per cent from December 2021 (previously 20 per cent), with subsequent investment of $173 million during FY2023 to maintain its 20 per cent interest from August 2022.

Exploration and appraisal Drilling and gatheringProcessing andtransportation Domestic customersLiquefaction and export customers 36 Annual Report 2023 Origin’s share of APLNG Underlying EBITDA increased by $355 million excluding the impact from 10 per cent ownership change in December 2021, primarily due to higher realised oil prices. • Commodity revenue and other income increased by $516 million19, primarily reflecting a higher realised oil price of US$103/bbl (A$154/ bbl) compared to US$74/bbl (A$103/bbl) in FY2022, together with higher domestic revenue attributed to market linked short term contract prices. Seven spot cargoes were delivered in FY2023 down from fifteen cargoes in FY2022 reflecting the impact of La Niña weather on production and the prioritisation of domestic market sales. • Operating expenses increased by $16119 million, driven by increased gas purchases to manage the portfolio (primarily through operational time swaps with other major producers), increased workover activity focused on reducing La Niña weather inventory backlog, commencement of a planned multi-year upstream gas processing maintenance program, inflationary impacts, higher royalties as a consequence of higher revenue and exploration asset write off. Origin’s share of depreciation and amortisation decreased by of $39 million, mainly reflecting the impact from 10 per cent ownership change in December 2021 and reduced well amortisation as a result of lower production. MRCPS interest expense decreased by $48 million to nil as MRCPS were fully repaid in FY2022. See Section 5.4 for details relating to the APLNG funding. 19 Origin's interest is 27.5 per cent.

Prior to 8 December 2021 it was 37.5 per cent. APLNG production volumes decreased 3 per cent compared to FY2022 reflecting the cumulative impact of the three consecutive years of La Niña weather, which restricted access to fields for workovers, drilling and optimisation activities during the first half of FY2023. The commencement of a planned multi-year upstream gas processing maintenance program in addition to unplanned non-operated outages also contributing to the decline in production. Production rebounded strongly in the second half of FY2023 with favourable drier weather. This allowed an increase in well workover activity and increasing the rates of online wells, which, coupled with production optimisation projects, increased overall production. Talinga Condabri North Pipeline ramped to full capacity and Orana South Loop Line also completed, enabling additional field production uplift and greater operational flexibility. This led to multiple daily operated production records, peaking at 1,618 TJ/day in May 2023. APLNG sales volumes decreased 3 per cent, reflecting lower production volumes during FY2023. The average realised LNG price increased 22 per cent to A$20.01/GJ driven by higher realised oil prices. The average realised domestic gas price increased 37 per cent to $8.54/GJ, primarily driven by market-linked short-term contract prices. 38 Annual Report 2023 Cash flow – APLNG 100% Underlying EBITDA Non-cash items in underlying EBITDA Change in working capital Operating cash flow1 Capital expenditure1 Interest income1 Acquisitions/disposals1 Loans (advanced to)/paid by shareholders Investing cash flow Project finance interest and transaction costs1 Repayment of project finance1 Other financing activities1 Repayment of lease liabilities1 Interest on lease liabilities1 MRCPS interest MRCPS buy-back Ordinary dividends paid Financing cash flow Net increase/(decrease) in cash and cash equivalents Effect of exchange rate changes on cash1 Net increase/(decrease) in cash and cash equivalents including FX movement Distributable cash flow1 FY23 ($m) 8,168 (40) 56 8,184 (481) 82 1 - (398) (311) (813) - (64) (27) - - (6,483) (7,698) 88 88 176 6,659 FY22 ($m) 6,876 (89) 283 7,070 (415) 7 68 51 (289) (233) (694) (22) (55) (15) (145) (3,544) (1,573) (6,281) 500 139 639 5,850 Change ($m) Change (%) 1,292 49 (227) 1,114 (66) 75 (67) (51) (109) (78) (119) 22 (9) (12) 145 3,544 (4,910) (1,417) (412) (51) (463) 809 19 (55) (80) 16 16 1,071 (99) (100) 38 33 17 (100) 16 80 (100) (100) 312 23 (82) (37) (72) 14 1 Included in distributable cash flow. Distributable cash flow represents the net increase in cash, including foreign exchange movements before MRCPS interest and buy-backs, and transactions with shareholders. APLNG generated distributable cash flow of $6,659 million in FY2023 at an effective oil price of US$103/bbl, up from $5,850 million at an effective oil price of US$74/bbl in the prior year. Cash distributions to Origin were $1,783 million in FY2023, in the form of unfranked ordinary dividends, up from $1,595 million in the prior year. APLNG accumulated tax loss position was US$1,760 million (US$528 million tax effected) at 30 June 2023, down from US$5,600 million at 30 June 2022. Once the accumulated tax losses have been utilised, APLNG will move towards paying tax, and franking dividends. The project finance facility requires APLNG to hold an amount of cash to service near-term operational and project finance obligations. As at 30 June 2023, APLNG held $1,720 million of cash, up from $1,544 million at 30 June 2022 primarily reflecting FX revaluation of US dollar balances. Non-cash items reflects the reversal of a prior period provision net of write-off of an exploration asset.

Capital expenditure increased $100 million, primarily driven by a change to well scope and more complex completion activities and non-operated well development programs. Operated upstream - Sustain costs increased $78 million reflecting higher fracture stimulation activities, and La Niña weather impacts on surface scope requiring additional rig support, along with La Niña weather risk mitigations. Non-operated expenditure increased $18 million due to increased activities in Fairview well development programs, partially offset by a decrease in the Arcadia Phase 2 development program and material completion of Bellevue drilling program in the prior year. 40 Annual Report 2023 6.3.2 Integrated Gas – Other This segment comprises Origin Integrated Gas activities that are separate from APLNG, and includes exploration interests in Beetaloo, Cooper-Eromanga, Canning and Browse Basin, interest in Hunter Valley Hydrogen Hub Project on Kooragang Island. This segment also includes overhead costs (net of recoveries) incurred as upstream operator and corporate service provider to APLNG, costs associated with growth initiatives such as hydrogen, and costs incurred in managing Origin’s exposure to LNG pricing risk and impacts of its LNG trading positions. In September 2022, Origin announced it will undertake a strategic review of all remaining exploration permits (excluding its interests in Australia Pacific LNG) with a view to exiting those permits over time, as the company focuses on its strategy and ambition to lead the energy transition. Beetaloo Basin (Northern Territory) In November 2022 Origin completed the sale of its interest in the Northern Territory’s Beetaloo Basin and received upfront consideration of $60 million. Origin will also receive a 5.5 per cent royalty based on wellhead revenues produced from the three Beetaloo permits. A non-cash post tax loss of $75 million in relation to the transaction was recorded. Origin has also executed a gas sale agreement conditional on a final investment decision being made and future development occurring. Cooper-Eromanga Basin (Queensland) Origin executed an agreement to transfer its 75 per cent interest and operatorship of five permits back to Bridgeport, and has surrendered the twelve permits in the Cooper-Eromanga Basin. The transaction is expected to complete in the first half FY2024. Canning Basin (Western Australia) An agreement has been executed with Buru Energy Limited to exit Origin’s interest in the Canning Basin and the transaction is now expected to complete in the first half FY2024. The terms of the sale provide for Origin to provide Buru with up to $4 million to fund a seismic survey and for Buru to provide Origin with future reimbursement payments of up to $34 million, conditional on the achievement of key development and production milestones.

Operating and Financial Review 41 Commodity hedging and trading summary FY2023 hedge positions realised a $235 million net loss, compared to a $189 million loss in FY2022. The FY2023 net loss included a hedge loss of $271 million associated with 5.4 MMbbl of oil swaps and 1.6MMbbl of oil producer collars which realised a hedge price of US$99/bbl. These hedge contracts were established over October 2020 to August 2021 during the height of the COVID pandemic to protect the company’s investment grade credit rating. Based on current forward market prices20, we estimate a net loss on oil, gas and FX hedging in FY2024 of $27 million.

Oil, gas and fx hedging FY23 actual (22) (271) 58 (235) FY22 actual (28) (137) (23) (189) FY24 estimate1 (2) (25) Origin has entered into oil and gas hedging instruments for the FY2024 and FY2025 periods to manage its share of APLNG oil and gas price risk based on the primary principle of protecting the Company’s investment grade credit rating and cash flows during volatile market periods and to satisfy conditions outlined in the Consortium's proposal. For FY2024, Origin’s share of APLNG related Japan Customs-cleared Crude (JCC) oil and Japan Korea Marker (JKM) gas price exposure is estimated to be approximately 17 MMboe and 18 tBtu respectively. As at 7 August 2023, we estimate that 41 per cent of JCC and 23 per cent of JKM have been priced (based on LNG contract lags) at approximately US$84/bbl and US$11/MMBtu respectively, before any hedging. As at 7 August 2023, Origin has separately hedged to provide downside protection for FY2024 using the following instruments: • 2.0 MMbbl of Brent USD swaps hedged at a fixed price of A$137/bbl; • 0.8 MMbbl of Brent producer collars struck between US$35/bbl and US$90/bbl; • 6.2 MMbbl of JCC USD swaps hedged at a fixed price of US$81/bbl • 4.2 tBtu of JKM futures hedged at a fixed price of US$16/MMBtu; and • US$205 million FX forwards hedged at a fixed rate of 0.70. As at 7 August 2023, 3.7 MMbbl of oil hedging and 0.4 tBtu JKM hedging have been priced at US$86/bbl and US$15/MMBtu respectively. Based on a forward oil price of US$87/bbl and forward JKM price of US$15/MMBtu, the effective prices of the remaining 4.5 MMbbl of oil hedging and 3.8 tBtu JKM hedging are US$82/bbl and US$16/MMBtu respectively. This would result in an effective oil price on the company's FY2024 approximate 17 MMboe oil exposure and 18 tBtu JKM exposure of US$85/bbl and US$15/MMBtu including hedges. Premium spend for this hedge position is A$2 million. The FY2025 hedge position consists of: • 6.2 MMbbl oil swaps hedged at a fixed price of US$76/bbl; • 3.5 tBtu JKM futures hedged at a fixed price of US$14/MMBtu; and • US$162m FX forwards hedged at a fixed price of 0.69. LNG hedging and trading In 2013, Origin established a Henry Hub linked contract to purchase 0.25 mtpa from Cameron LNG for a period of 20 years, with the first cargo delivered to Origin in June 2020. In 2016, Origin established a medium term contract with ENN LNG Trading Company Limited to sell ~0.28 mtpa commencing in FY2019. As at 30 June 2022, a non-cash onerous provision of $397 million was held in relation to this contract, reflecting stronger LNG prices relative to Brent oil prices. In FY2023, a reduction in the non-cash onerous provision of $335 million was recognised, with the provision revalued to $62 million as at 30 June 2023, reflecting a decline in near-term LNG price assumptions relative to Brent oil prices. These contracts and derivative hedge contracts that manage the price risk associated with the physical LNG contracts form part of an LNG trading portfolio. Based on market forward prices as at 7 August 2023, the FY2024 LNG trading EBITDA is expected to be between $40 - 60 million. Across both FY2025 and FY2026, the total LNG trading EBITDA is expected to be between $450 - 650 million. This outlook remains subject to market prices on unhedged volumes, operational performance and delivery risk of physical cargoes, and shipping and regasification costs. 20 As at 7 August 2023. 42 Annual Report 2023 7 Risks related to Origin’s future financial prospects The scope of operations and activities means that Origin is exposed to risks that can have a material impact on our future financial prospects. Material risks, and the Company’s approach to managing them, are summarised below. Risk management framework Overseen by the Board and the Board Risk Committee, Origin’s risk management framework supports the identification, management and reporting of material risks. Risks are identified that have the potential to impact the delivery of business plans and objectives. Risks are assessed using a risk toolkit that considers the level of consequence and likelihood of occurrence using consistent risk assessment criteria. The risk framework incorporates a "three lines of defence" model for managing risks and controls in areas such as health and safety, environment, climate change, financial, reputation and brand, legal and compliance and social impacts. All employees are responsible for making risk-based decisions and managing risk within approved risk appetite and specific limits. The Board reviews Origin’s material risks each quarter and assesses the effectiveness of the Company’s risk management framework annually in accordance with the ASX Corporate Governance Principles and Recommendations. Three lines of defence Line of defence First line Lines of business Second line Oversight functions Third line Internal audit Responsibility Primary accountability Identifies, assesses, records, prioritises, manages and monitors risks. Management Provides the risk management framework, tools and systems to support effective risk management. Management Provides assurance on the effectiveness of governance, risk management and internal controls. Board, Board Committees and Management Origin's risk framework supports the identification and management of emerging risks and escalating threats. During FY2023, the accelerating energy transition, as well as ongoing geopolitical risks, inflationary pressures, and supply chain disruptions were key threats to operational and financial performance. These threats required ongoing response and management across many of our existing material risks to minimise impacts. Our priorities remain ensuring the continuity of operations and supporting activities to provide essential services to our customers, and maintaining our financial resilience to respond to changes in global markets. Material risks The risks identified in this section have the potential to materially affect Origin’s ability to meet our business objectives and impact its future financial prospects. These risks are not exhaustive and are not arranged in order of significance. Strategic risks Strategic risks arise from uncertainties that may emerge in the medium to longer term and, while they may not necessarily impact on short-term profits, can have an immediate impact on the value of the Company. These strategic risks are managed through continuous monitoring and reviewing of emerging and escalating risks, ongoing planning and the allocation of resources, and evaluation by Management and the Board. Risk Consequences Management Competition Origin operates in a highly competitive retail environment which can result in pressure on margins and customer losses. Competition also impacts Origin’s wholesale business, with generators competing for capacity and fuel and the potential for gas markets to be impacted by new domestic gas resources, LNG imports and the volume of gas exports. Origin is well placed to respond to prevailing headwinds due to the diversified nature of our business, however we are exposed to coal supply challenges relative to vertically integrated organisations with coal businesses or those with long term legacy coal contracts. • Our strategy to mitigate the impact of this risk on our retail business is to provide customers with value for money and exceptional service, while continuously focusing on maintaining our cost leadership and innovation. The migration of our business to Octopus Energy’s Kraken platform should see us maintain our churn advantage over competitors through extending leadership in cost, products and service. • We endeavour to mitigate the impact of this risk on our wholesale business by sourcing competitively priced fuel to operate our generation fleet and through efficient operations to optimise flexibility in our fuel, transportation and generation portfolio. Operating and Financial Review 43 Risk Consequences Management Technological developments / disruption Changes in demand for energy Origin is exposed to risks and opportunities relating to new digital and low-carbon technologies. Distributed generation is empowering consumers to own, generate and store electricity, which results in less energy consumption from the grid. Technology is allowing consumers to understand and manage their power usage through smart appliances, which could potentially disrupt the existing utility relationship with consumers. Technology also allows customers to have increased awareness of the impact of when they consume energy and the source of that energy. Advances in technology and the abundance of low-cost data acquisition, communication and control has the potential to create new business models and introduce new competitors. The volume or source of energy demanded by customers could change due to price, consumer behaviour, community expectations, mandatory energy efficiency schemes, Government policy, weather and other factors. Demand for the energy is also expected to grow due to increased electrification; for example, hydrogen, e-mobility and distributed infrastructure as a service, providing new market opportunities. The current global energy market environment may impact the supply and cost of energy to our customers, and this could have an adverse impact on our reputation with customers and the community. Any change in demand for energy could impact Origin’s revenues and future financial performance. Regulatory policy Origin has broad exposure to regulatory policy change and other government interventions. Changes to policy and other government interventions can impact financial outcomes and, in some cases, change the commercial viability of existing or proposed projects or operations. Specific areas subject to review and development include government subsidies for building new generation or transmission capacity, direct government investment in generation, energy market design, domestic and international climate change policies, domestic gas market interventions, wholesale and retail price, consumer protection regulation, and royalties and taxation policy. • Origin actively participates and invests in technological developments through local and global start-up accelerator programs, trialling new energy technology and new products and business models. • In parallel, we are growing our distributed generation and home energy services businesses and endeavouring to mitigate the impact of this risk on our core energy businesses by offering superior service and innovative products and reducing cost to serve. • Origin is pursuing opportunities in low-carbon technologies such as hydrogen, e-mobility and carbon management. • Our strategy of increasing renewable energy in our portfolio and investing in new technology and products, such as storage, the virtual power plant (VPP) and lower carbon customer solutions, supports Origin’s ability to meet future increases in energy demand. • We use the flexibility in our gas supply and peaking generation capacity, as well as the flexibility of Eraring Power Station, to manage the intermittency of renewables and maintain reliable supply for customers. • Origin is partially mitigating the impact of this risk by developing data-based customer propositions and better predicting customer demand through our artificial intelligence orchestration platform, or VPP, which connects and controls distributed assets and Internet of Things (IoT) devices, and by applying advanced data analytics capability. • Origin contributes to the policy process with federal, state and territory governments by actively participating in public policy debate, proactively engaging with policy makers and participating in public forums, industry associations, think tanks and research. • We advocate directly with key members of governments, opposition parties and bureaucrats to achieve sound policy outcomes that align with our strategy, purpose and commercial objectives. Origin also makes formal submissions to relevant government policy inquiries. • Origin actively and publicly promotes the customer and economic benefits that flow from our activities in deregulated energy markets. 44 Annual Report 2023 Climate risks Climate change risk is considered a strategic risk for Origin. Under the Task Force on Climate-related Financial Disclosures (TCFD) framework, Origin’s climate-related risks can be classified as transitional or physical. Many of our climate-related risks are managed within our existing risks and the table below provides a summary of our climate-related risks under the TCFD's categories. TCFD Risk Type Consequences Management Transition Risks Policy and Legal Risk time horizon: Short – Medium Changes to government policy and regulation in relation to, and resulting from, climate change may present risks and opportunities for Origin, including: • regulatory intervention in the national electricity and gas markets; • carbon pricing (including carbon markets, border adjustment and taxes); • the emergence of new climate-related legislation or reporting requirements; • government investment in energy infrastructure and generation including partnerships; • government grants and subsidies to innovate and incentivise market development; and • development approvals and planning and zoning laws. These changes may impact Origin's asset values, operating costs, or investment decisions. There is an increased risk of climate change-related litigation globally and in Australia. Any litigation would incur legal costs and potential penalties, compensation payments or settlement costs and may directly or indirectly influence future operational strategy. • Origin continues to advocate for coordinated and long- term energy policy at the national level to give industry the confidence to invest in new electricity generation and gas supply. • We engage proactively with all levels of government and regulatory bodies on energy and climate policy, including through policy submissions, participating in think tanks, research and various industry associations. This consultation helps to support government responses in a rapidly evolving landscape. • Climate-related commitments and disclosures are regularly reviewed and updated to take into consideration up to date science, regulatory requirements and stakeholder expectations. • Origin carries out scenario based planning and portfolio assessment that consider potential changes to government policy and regulation. Technology Risk time horizon: Short – Long The development of new technologies may be required to assist Origin to meet its medium to long-term emissions reduction targets and ambitions, however there is uncertainty regarding the efficacy, timing, cost and availability of those technologies. The growth of low emissions technologies, distributed generation, and demand management enabled by technologies could result in lower demand (and revenue) for existing products, however these also present new market opportunities and potential revenue streams. Market Risk time horizon: Short - Medium The energy transition represents a period of significant change and volatility which presents both risks and opportunities for Origin. The ongoing decarbonisation of energy markets and lower demand for fossil fuels in some markets could result in: • • the reduced lifespan of existing carbon-intensive assets and potential for stranded assets; the continued electrification of some sectors that currently depend on fossil fuels, with potential to increase overall demand for electricity; • a change in the competitive landscape and the development of new markets and business models that Origin can participate in, as cleaner fuels, renewables, storage, and distributed generation markets evolve; and • energy market price volatility, as both the volume and source of energy supply and demand shift. Origin's response to these market changes may have a positive or negative influence on our future financial prospects including our earnings, asset values, and investments. Origin's financial performance during the energy transition will also be influenced by the timely and affordable access to: • capital to support our strategy and growth aspirations; • land and infrastructure, including the necessary network transmission capacity to enable investment in renewables and other third-party infrastructure; and • Origin participates in local and global start-up accelerator programs, trialling new energy technology and exploring investments in new products or business models. • We are growing our offerings in emerging technologies and markets. • More details can be found in the ‘Technological developments / disruption’ strategic risk above. • Our ambition is to lead the energy transition through cleaner energy and customer solutions, and we are strategically positioned to benefit from the energy transition. • We are focused on growing our offering of lower carbon solutions, including solar and batteries, electric vehicles and demand management, to help our customers decarbonise. We are also accelerating growth in renewables and cleaner energy. We have an ambition to grow our portfolio of renewables and storage to 4 GW by 2030, and in April 2023 we took a final investment decision on the first stage of a large-scale battery at the Eraring Power Station. We are also exploring both domestic and export market opportunities for hydrogen and ammonia. • We believe there will continue to be a long-term role for natural gas to maintain energy security and support the energy transition. Our portfolio of gas-fired peaking plants will continue to have an important role to play in Australia’s energy transition to support intermittent renewable output and maintain reliable electricity supply. • We intend to ensure that our capital expenditure portfolio is consistent with our emissions reduction targets. Relevant investments in growth projects will be evaluated against our emissions reduction targets and our ambition to be net zero emissions by 2050. Climate change scenario analysis plays a role in our assessment of the assets we should hold, invest in, dispose of and acquire. Operating and Financial Review 45 TCFD Risk Type Consequences Transition Risks Management • the necessary inputs (including skills, commodities, and other supplies) to develop renewable and cleaner energy assets in an ethical manner. • Origin aims to deploy capital in areas that deliver value to shareholders and are consistent with our strategy, targets and ambitions. • Origin is investing in new technology to support our ability to manage the supply / demand balance in the electricity market. This includes scaling an artificial intelligence orchestration platform, or VPP, which connects, and controls distributed assets and IoT devices, and applies advanced data analytics capability to smart meter data to better predict customer demand and develop data-based customer propositions. The VPP provides Origin with an important tool to manage the supply/demand balance in the electricity market. • We released our Climate Transition Action Plan in 2022, outlining our ambition to lead the energy transition through cleaner energy and customer solutions. Included in the plan are short and medium-term targets for increased emissions reduction across Origin, towards our long-term ambition to be net zero in Scope 1, 2 and 3 emissions by 2050. We believe our updated medium-term emissions intensity target and our long-term net zero emissions ambition are consistent with the goals of the Paris Agreement to limit the increase in the average global temperature to 1.5°C above pre-industrial levels.1 • Origin has been using the TCFD as the framework for our external climate disclosures since 2018. • Origin proactively engages with our capital providers and other financial stakeholders to ensure they are well informed of our climate change strategy, targets and ambitions. • We engage with communities to understand, mitigate and report on environmental risks associated with our projects and operations, including those relating to climate change. • We have put in place principles for a just energy transition which guide our approach and are underpinned by open, inclusive and transparent engagement. • Origin is applying advanced data analytics capability to better predict customer demand and to increase our supply of renewables and flexible capacity to meet changes in demand. • More details are in the ‘Changes in demand for energy’ strategic risk above. Reputation Risk time horizon: Short Our strategy, emissions reduction targets and ambitions may fail to meet stakeholder expectations. This includes the timing and alignment of our portfolio decisions, and how we set, measure and report on climate change targets. This could result in: • increased cost of, or restricted access to, debt and equity capital and insurance; • adverse impacts to our social licence to operate and our reputation among our communities, customers, suppliers and other stakeholders; and • challenges attracting and retaining talent. Our path through the energy transition will have an impact on our people, communities and customers as our business changes, including the planned closure of the Eraring coal-fired power station as early as August 2025. There is a risk we fail to meet stakeholder expectations in relation to a 'just energy transition'. Changing weather patterns may influence the demand for energy, which could impact Origin’s revenues and future financial performance. Physical Risks Chronic Risk time horizon: Short – Long Acute Risk time horizon: Short – Long Changing and more frequent and severe weather conditions, including floods, droughts, bushfires, and extreme temperature events could disrupt our operations or impact the efficacy of our assets, and supporting distribution and transmission infrastructure. This could lead to increased operating costs, increased maintenance and capital expenditure, the risk of environmental incidents and higher insurance costs or restrictions on accessing insurance. • Origin has extreme weather event preparation processes including comprehensive seasonal readiness activities and emergency response plans. • Our operational planning and design processes incorporate extreme weather events, while investment decisions for major growth projects. incorporate potential financial losses from natural disasters. 1 Pursuant to the methodology outlined in the Climate Transition Action Plan. Time horizons: Short-term: up to three years; Medium-term: three to 10 years; Long-term: beyond 10 years 46 Annual Report 2023 Financial risks Financial risks are the risks that directly impact the financial performance and resilience of Origin. Consequences Management Risk Commodity Foreign exchange and interest rates We have a long-term exposure to international oil, LNG and gas prices through the sale and purchase of domestic gas, LNG and LPG, and our investment in Australia Pacific LNG. Pricing can be volatile and driven by global macroeconomic events. Downward price movements can impact cash flow, financial performance, reserves and asset carrying values. Some of Origin’s long-term domestic gas purchase agreements and Australia Pacific LNG's LNG sale agreements contain periodic price reviews. Following each review, pricing may be adjusted upwards or downwards, or remain unchanged. The prices and volumes for wholesale electricity that Origin sources to on-sell to customers are volatile and influenced by many factors, including generation availability, the pricing of generation fuels (coal and gas), and weather. Fluctuations in coal and gas prices also impact the margins of Origin's own generation portfolio. Energy Markets also has exposures to contracted volumes of coal not being delivered which could result in lower output or higher costs to meet customer demand. Different commodity prices that have historically moved in a correlated fashion may see that correlation break down. It would be disadvantageous for Origin if the domestic wholesale energy costs incurred by Energy Markets were high, but the international oil and LNG prices obtained by Australia Pacific LNG were low. Origin has exposures through principal debt and interest payments associated with foreign currency and Australian dollar borrowings, through the sale and purchase of gas, LNG and LPG, and through its investments in Australia Pacific LNG and Octopus Energy. Interest rate and foreign exchange movements could lead to a decrease in revenues or an increase in payments in Australian dollar terms. Liquidity and access to capital markets Our business, prospects and financial flexibility could be adversely affected by a failure to appropriately manage our liquidity position, or if markets are not available at the time of any financing or refinancing requirement. Credit and counterparty Some counterparties may fail to fulfil their obligations (in whole or part) under major contracts. • Commodity exposure limits are set by the Board to manage the overall financial exposure that Origin is prepared to take. • Origin's commodity risk management process monitors and reports performance against defined limits in accordance with our ‘Commodity Risk Management System’. • Commodity price risk is managed using various controls, most notably financial hedging contracts (derivatives), which are widely available for Origin’s international commodity exposures and wholesale electricity exposures. • For each periodic price and supply review, a negotiation strategy is developed that considers external market advice and utilises both external and in-house expertise. • Risk limits are set by the Board to manage the overall exposure. • Origin's treasury risk management process monitors and reports performance against defined limits. • Foreign exchange and interest rate risks are managed through a combination of physical positions and derivatives. • We actively manage our liquidity position through cash flow forecasting and maintenance of minimum levels of liquidity as determined under Board approved limits. • Counterparty risk assessments are regularly undertaken and where appropriate, credit support is obtained to manage counterparty risk. • AEMO credit is managed daily to ensure compliance with the market rules, ensuring management forecasts the collateral required to continue to meet spot market obligations for all AEMO markets. Operating and Financial Review 47 Operational risks Operational risks arise from inadequate or failed internal processes, people or systems or from external events. Risk Consequences Management Safe and reliable operations Environmental and social We are exposure to reliability or major accident events that may impact our assets, our licence to operate or financial prospects. This includes loss of containment, cyber-attack and security incidents, unsafe operations, and natural hazards and events that may result in harm to our people, environmental damage, additional costs, production loss, property damage, third party impacts, and reputational impacts. A production outage or constraint, network or IT systems outage, would affect Origin's ability to deliver electricity and gas to customers. A serious incident or a prolonged outage may also damage Origin’s financial prospects and reputation. • Core operations are subject to a comprehensive framework of controls, management systems and operational performance monitoring to manage the design, operational and technical integrity of our assets and associated operational activities. Origin’s standards and controls are designed to meet regulatory and industry standards in all operations. • Origin personnel are appropriately trained and licensed to perform their operational activities. • We maintain an extensive insurance program to mitigate consequences by partially transferring financial risk exposure to third parties where commercially appropriate. An environmental incident or failing to consider and adequately mitigate environmental, social and socio-economic impacts on communities and the environment has the potential to cause environmental impact, community action, regulatory intervention, legal action, reduced access to resources and markets, impacts to our licence to operate and reputation and increased operating costs. Community concerns regarding environmental and social impacts associated with our activities may also give rise to unrest amongst community stakeholder groups and activism which may impact the company's reputation. A third party’s actions may also result in delay in Origin carrying out its approved development and operational activities. NGOs, landholders, community members and other affected parties can seek to prevent or delay Origin’s activities through court litigation, preventing access to land and extending approval pathway time frames. • Core operations are subject to a comprehensive framework of environmental controls, management systems and operational performance monitoring to manage operational exposure to the environment. Origin’s standards and controls are designed to meet regulatory and industry standards in all operations. • Origin personnel are appropriately trained and licensed to perform their operational activities. • We engage with communities to understand, mitigate and report on environmental and social risks associated with our projects and operations. • At a minimum, the management of environmental and social risks meets regulatory requirements. Where practical, our management extends to the improvement of environmental values and the creation of socio- economic benefits. • Origin has a cultural awareness learning framework to build awareness of Aboriginal and Torres Strait Islander cultures, histories and achievements. Origin maintains and implements Native Title Agreements and Cultural Heritage Management Plans with Traditional Owners where appropriate. We engage with impacted groups and consider cultural heritage protection as part of ongoing operations and at project stage gates. • A dedicated Board committee oversees safety and sustainability. The committee receives regular reporting on the highest rated environmental risks and mitigants, and reviews significant incidents and near misses. The committee also receives updates on our engagement with Traditional Owners. • We engage with stakeholders before seeking relevant approvals for our development and operational activities. This engagement continues through the life of the project and during operations. • A cyber security strategy is in place and is regularly updated to cater for emerging threats, security regulation and stakeholder expectations. • A robust security monitoring and incident response process exists and is tested on a regular basis. In the event of an incident, Origin is supported by an external incident response and forensics firm. • We undertake regular independent security assurance to assess the resilience of our digital channels and internal security controls. • Employees undertake compulsory cyber awareness training, including how to identify phishing emails and hoe to keep data safe, and are subject to a regular program of random testing. Cyber security A cyber security incident could lead to a breach of privacy, loss of and/or corruption of commercially sensitive data, and/or a disruption of critical business processes. This may adversely impact customers, the Company’s business activities and reputation and brand. 48 Annual Report 2023 Risk Consequences Management APLNG gas reserves, resources and deliverability There is uncertainty about the productivity, and therefore economic viability, of resources and developed and undeveloped reserves. As a result, there is a risk that actual production may vary from that estimated, and in the longer term, that there will be insufficient reserves to supply the full duration and volumes to meet contractual commitments. As at 30 June 2023 Australia Pacific LNG’s identified reserves and resources are estimated to be greater than its contractual supply commitments on a volume basis. However, given the inherent uncertainty in forecasting future production rates, there is a risk that the rate of gas delivery required to meet Australia Pacific LNG’s committed gas supply agreements may not be able to be met for the later years in the life of existing contracts. Conduct and compliance Unlawful, unethical or inappropriate conduct that falls short of community expectations could result in penalties, reputational/ brand damage, loss of customers and adverse financial impacts. Origin’s financial prospects and operations are underpinned by our licence to operate which requires compliance with stakeholder commitments, regulations, and laws. For example, requirements for dealing with vulnerable customers, privacy, and insider trading. Joint venture Third party joint venture operators may have economic or other business interests that are inconsistent with Origin’s own and may take actions contrary to the Company’s objectives, interests or standards. This may lead to potential financial, reputational and environmental damage in the event of a serious incident. • Australia Pacific LNG integrates all available subsurface data to develop insights into regional prospectivity allowing identification and prioritisation of plays and prospects for exploration to mature contingent and prospective resources. • Australia Pacific LNG monitors reservoir performance and adjusts development plans accordingly. Australia Pacific LNG continually takes steps to further strengthen the supply base such as lowering costs and identifying new plays. • Australia Pacific LNG is progressing an exploration campaign that if successful, could increase long term supply. • Australia Pacific LNG continues to review business development opportunities for long term gas supply, and has the ability to substitute gas or LNG to meet contractual requirements if required. • Origin’s people are trained on the key laws and regulations that apply to their activities and operations or on the processes that underpin compliance with laws and regulations. • Origin’s Purpose, Values, Behaviours and Code of Conduct guide conduct and decision making across the Company. • All our people are trained in our Code of Conduct, and we conduct training for insider trading, privacy and competition and consumer law every year. • Conduct risk and Compliance are identified as material risks within Origin’s risk management framework and are a continuing area of focus for regulators. These risks are regularly reported to the Board Risk Committee. Controls specific to the different parts of Origin’s business are the accountability of Business Units and are subject to assurance activities, including internal audits. • We apply a number of governance and management standards across our various joint venture interests to provide a consistent approach to managing them. • Origin actively monitors and participates in its joint ventures through participation in their respective boards and governance committees. Operating and Financial Review 49 8 APLNG reversion In 2002, APLNG acquired various CSG interests from Tri-Star that are subject to reversionary rights and an ongoing royalty in favour of Tri-Star. If triggered, the reversionary rights require APLNG to transfer back to Tri-Star a 45 per cent interest in those CSG interests for no additional consideration. The reversion trigger will occur when a calculation of the revenue from the sale of petroleum from those CSG interests, plus any other revenue derived from or in connection with those CSG interests, exceeds the aggregate of all expenditure relating to those CSG interests plus interest on that expenditure, royalty payments and the original acquisition price. The affected CSG interests represent approximately 18 per cent of APLNG’s 3P CSG reserves (as at 30 June 2023), and approximately 19 per cent of APLNG’s 2P CSG reserves (as at 30 June 2023). Tri-Star served proceedings on APLNG in 2015 (‘2015 proceeding’) claiming that reversion occurred as early as 1 November 2008 following ConocoPhillips’ investment in APLNG, on the assertion that the equity subscription monies paid by ConocoPhillips, or a portion of them, were revenue for purposes of the reversion trigger (the ConocoPhillips reversion claim). Tri-Star has also claimed in the alternative that reversion occurred in 2011 or 2012 following Sinopec’s investment in APLNG (the Sinopec reversion claim). These claims are referred to in this document as Tri-Star’s "past reversion" claims. Tri-Star has made other claims in the 2015 proceeding against APLNG relating to other aspects of the reversion trigger calculation (including as to the calculation of interest, calculation of revenue and the nature and quantum of APLNG’s expenditures that can be included), the calculation of the royalty payable by APLNG to Tri-Star, rights in respect of infrastructure, and claims relating to gas sold by APLNG following the alleged reversion dates. APLNG denies these claims and is defending the proceedings. If Tri-Star’s past reversion claims are successful, then Tri-Star may be entitled to an order that reversion occurred as early as 1 November 2008. If the court determines that reversion has occurred, then APLNG may no longer have access to the reserves and resources that are subject to Tri-Star’s reversionary interests and may need to source alternative supplies of gas (including from third parties) to meet its contracted commitments. There are also likely to be a number of further complex issues that would need to be resolved as a consequence of any such finding in favour of Tri-Star. These matters will need to be determined by the court (either in the current or in separate proceedings) or by agreement between the parties, and they include: • • • the terms under which some of the affected CSG interests will be operated where currently there are no joint operating agreements in place; the amount of Tri-Star’s contribution to the costs incurred by APLNG in exploring and developing the affected CSG interests between the date of reversion and the date of judgment, which APLNG has stated in its defence and counter-claim are in the order of $4.56 billion (as at 31 December 2019) if reversion occurred on 1 November 2008; and the consequences of APLNG having dealt with Tri-Star’s reversionary interests between the date of past reversion and the date of judgment, including the gas produced from them. Tri-Star has: – estimated the value of such gas which it has been unable to take since the alleged reversion, calculated by reference to the sale of gas as LNG and gas to domestic customers, to be approximately $3.37 billion (as at 31 March 2019) and approximately $1.3 billion per annum thereafter. Tri- Star claims that the value of gas sold as LNG should be assessed by reference to the revenue derived by APLNG or its affiliates from LNG sales since the alleged reversion, being approximately $2.5 billion (as at March 2019), or $2.4 billion (as at March 2019) if the proceeds from the sale of LNG is determined to be calculated net of liquefaction costs; – conceded in its claim that certain costs for processing and transportation of that gas would need to be deducted from the value of gas to calculate the quantum of its claim, but has not quantified those costs; and – alleged that it should be paid the value of such gas after deduction of those costs or is otherwise entitled to set-off the value of such gas from any amount owing to APLNG arising from APLNG’s counter-claim for contribution to the costs incurred by APLNG in exploring and developing the affected CSG interests between the date of reversion and the date of judgement; and • if reversion occurred: – the extent of the reversionary interests principally with respect to Tri-Star’s ownership and/or rights to use or access certain project infrastructure; and – the repayment by Tri-Star of the ongoing royalty which has been paid by APLNG since reversion, resulting from its mistake as to the occurrence of the reversion trigger. If APLNG is successful in defending Tri-Star’s past reversion claims in the 2015 proceeding, the potential for reversion to otherwise occur in the future in accordance with the reversion trigger will remain. In 2017, Tri-Star commenced separate proceedings against APLNG (‘2017 proceeding’) which allege that APLNG breached three CSG joint operating agreements by failing to offer Tri-Star (and the other minority participants in those agreements) an opportunity to participate in the “markets” alleged to be constituted by certain of APLNG’s LNG and domestic gas sales agreements, including the Sinopec and Kansai LNG sale agreements entered into by APLNG in 2011 and 2012. Tri-Star has alleged that it should have been offered participation in those sales agreements for its share of production from those three CSG joint ventures referable to both its small participating interests and its reversionary interests in those joint ventures (the markets claim). In that regard, Tri-Star is claiming, amongst other things, damages and/or an order that APLNG offer Tri-Star (and the other minority participants in those CSG joint operating agreements) the opportunity to participate in those sales agreements for their proportionate share of production from those three CSG joint ventures. APLNG denies these claims and is defending these proceedings. In September 2019, Tri-Star made further claims in the 2017 proceeding relating to: • the nature and scope of the obligations of APLNG as operator pursuant to the CSG joint operating agreements; • Tri-Star’s ownership and/or rights to use or access certain project infrastructure; and • APLNG’s entitlement as operator to charge (both historically and in the future) certain categories of costs under the relevant CSG joint operating agreements. APLNG filed defences and counterclaims in both proceedings in April and May 2020. In December 2020, Tri-Star filed replies and answers in both proceedings. APLNG filed its rejoinders in the 2015 proceeding and the 2017 proceeding in February and April 2021 respectively. APLNG filed a further amended defence and counterclaim in the 2015 proceeding in December 2021. In September 2021, Tri-Star filed and served an application in both proceedings for questions to be determined separately (or further or alternatively referred to a referee to conduct an inquiry into and prepare a report to the court on those questions). The questions proposed for separate determination in those applications included 50 Annual Report 2023 the issue of whether the 2008 ConocoPhillips subscription monies are revenue for the purposes of the calculation of the reversion trigger. APLNG opposed those applications. The applications were heard in April 2022 and both were ultimately dismissed by the Court. Tri-Star recently notified APLNG that it intends to seek to amend its claims in both proceedings. In relation to the 2017 proceedings, Tri-Star’s proposed amendments include it not continuing with the markets claim. In relation to the 2015 proceedings, Tri-Star’s proposed amendments include: • not continuing with the Sinopec reversion claim (that is, the claim that reversion occurred in 2011 or 2012, following Sinopec’s investment in APLNG); • • the addition of an alternative claim that if the ConocoPhillips reversion claim is not successful, the reversion trigger nevertheless occurred by no later than 1 August 2022; the addition of alternative bases for Tri-Star’s claims for compensation or damages relevant to the consequences of the alleged past reversion, including as: – compensation calculated on the basis of loss of opportunity to sell the affected CSG interests in 2008 or 2009; – equitable compensation calculated on the basis of the ‘market value’ of the gas produced from the affected CSG interests since the alleged reversion on 1 November 2008); or – an account of the profits earned by APLNG or its affiliates from the affected CSG interests since 1 November 2008 with Tri-Star asserting that the revenue received by APLNG for that gas is to be calculated in a similar manner to the existing claim. As to the proposed claim for equitable compensation, Tri-Star asserts that the “market value” of the gas should be determined by reference to the wholesale spot price for domestic gas on the East coast of Australia as at the date of trial or, alternatively, by reference to the wholesale gas market prices for the East coast of Australia as at the relevant date the gas was sold plus compound interest. Tri-Star concedes that certain processing and transportation costs (which have not been quantified by Tri-Star) will also need to be deducted to determine the quantum of this claim. There are presently a number of uncertainties as to the quantum of this claim, if it were able to be established by Tri-Star, including details of Tri-Star’s calculations as to the market value of the gas, the amount of costs to be deducted, changes to the amount claimed to account for sales of gas up to the date of trial and the prevailing relevant prices at, and ahead, of that date. Tri-Star has not yet served a final version of its proposed amended pleadings and will need the leave of the Court to file any such amendments. If leave is granted, once Tri-Star files its amended claims and statements of claim, APLNG will prepare and file amended defences and counterclaims in response to defend the amended claims. The parties may also need to prepare replies and rejoinders. Once that process is finalised, the Court will make further orders for the conduct of the two proceedings. Before the proceedings are set down for trial, the Court would ordinarily order a number of procedural steps to be completed by the parties, including document disclosure, evidence preparation and exchange and pre-trial mediation. The process that will be followed in the 2015 and 2017 proceedings (and the procedural timetable) will depend on the decisions of the Court and is difficult to predict at this stage. If APLNG is not successful in defending all or some of the claims being made in the proceedings by Tri-Star, APLNG’s financial performance may be materially adversely impacted and the amount and timing of cash flows from APLNG to its shareholders, including Origin, may be significantly affected. Operating and Financial Review 51 Statutory Profit and Underlying Profit is provided in Section 5.1 of this OFR. Certain other non-IFRS financial measures are also included in this OFR. These non-IFRS financial measures are used internally by management to assess the performance of Origin’s business and make decisions on allocation of resources. Further information regarding the non-IFRS financial measures is included in the Glossary of this OFR. Non-IFRS financial measures have not been subject to audit or review. Certain comparative amounts from the prior corresponding period have been re-presented to conform to the current period's presentation. Emissions data Origin reports its Scope 1 and Scope 2 emissions under the National Greenhouse and Energy Reporting Act, 2007 (NGER)21. Origin calculates Scope 3 emissions based on the Greenhouse Gas Protocol’s Corporate Value Chain (Scope 3) Accounting and Reporting Standard22 and Scope 3 guidance documents23. Due to the inherent uncertainty and limitations in measuring emissions under the calculation methodologies used in the preparation of such data, all emissions data or references to emissions volumes (including ratios or percentages) in this presentation are estimates. Where data is not available due to timing, Origin applies a reasonable estimation methodology. Where applicable, Origin revises prior year data to update prior estimates and align with external reporting requirements such as NGER. Enforceable Undertaking with SafeWork NSW In March 2020 an explosion and fire occurred at Origin Energy’s Minto LPG Terminal, New South Wales while a worker was filling LPG cylinders. No injuries were sustained. On 10 August 2023, SafeWork NSW accepted an Enforceable Undertaking (EU) from Origin Energy LPG Limited (ACN 000 508 369) (Origin Energy LPG) in accordance with Part 11 of the Work Health and Safety Act 2011. The EU requires Origin Energy LPG to carry out the following key actions to deliver benefits to the workplace, industry and the community: • hosting a series of workplace and community events which will seek to prevent and reduce psychosocial risks in the workplace and the community, promoting awareness of mental health and early preventative measures; • developing guidance materials for industry and community regarding safely working with or in the vicinity of gas cylinders, tanks, gas systems and gas appliances that may be affected by major flood or storm events; and • engaging subject matter experts to develop updated industry guidance on hazards, risks and control measures in relation to electrostatic discharge as a potential ignition source for LPG or LPG vapour. This disclosure has been made under the terms of the EU and acknowledges acceptance of the EU by Origin Energy LPG . 9 Important information Forward looking statements This Operating and Financial Review (OFR) contains forward looking statements, including statements of current intention, statements of opinion and predictions as to possible future events and future financial prospects. Such statements are not statements of fact and there can be no certainty of outcome in relation to the matters to which the statements relate. Forward looking statements involve known and unknown risks, uncertainties, assumptions and other important factors that could cause the actual outcomes to be materially different from the events or results expressed or implied by such statements, and the outcomes are not all within the control of Origin. Statements about past performance are not necessarily indicative of future performance. This OFR also contains forward looking statements in the form of scenario analysis. These are based on management’s current expectations and reflect judgments, assumptions, estimates and other information available as at the date of this OFR and/or the date of Origin’s planning processes or scenarios analysis processes. There are inherent limitations with scenario analysis and it is difficult to predict which, if any, of the scenarios might eventuate. Scenarios do not constitute definitive outcomes or probabilities, and scenario analysis relies on assumptions that may or may not be, or prove to be, correct and may or may not eventuate. Scenarios may also be impacted by additional factors to the assumptions disclosed. Neither the Company nor any of its subsidiaries, affiliates and associated companies (or any of their respective officers, employees or agents) (the ‘Relevant Persons’) makes any representation, assurance or guarantee as to the accuracy, completeness or likelihood of fulfilment of any forward looking statement any assumption on which a forward looking statement is based. The forward looking statements in this OFR reflect views held only at the date of this report and except as required by applicable law, the Relevant Persons disclaim any obligation or undertaking to publicly update any forward looking statements whether as a result of new information or future events. Information on likely developments in the Company’s business strategies, prospects and operations for future financial years and the expected results that could result in unreasonable prejudice to the Company (for example, information that is commercially sensitive, confidential or could give a third party a commercial advantage) has not been included in this OFR. The categories of information omitted include forward-looking estimates and projections prepared for internal management purposes, information regarding the Company’s operations and projects, which are developing and susceptible to change, and information relating to commercial contracts. Non-IFRS financial measures This OFR and Directors’ Report refers to Origin’s financial results, including Origin’s Statutory Profit and Underlying Profit. Origin’s Statutory Profit contains a number of items that when excluded provide a different perspective on the financial and operational performance of the business. Income Statement amounts, presented on an underlying basis such as Underlying Profit, are non-IFRS financial measures, and exclude the impact of these items consistent with the manner in which senior management reviews the financial and operating performance of the business. Each underlying measure disclosed has been adjusted to remove the impact of these items on a consistent basis. A reconciliation and description of the items that contribute to the difference between 21 National Greenhouse and Energy Reporting NGER (cleanenergyregulator.gov.au) 22 Corporate Value Chain (Scope 3) Standard | Greenhouse Gas Protocol (ghgprotocol.org) 23 Scope 3 Calculation Guidance | Greenhouse Gas Protocol (ghgprotocol.org) 52 Annual Report 2023 Appendix 1 Deferred Tax Liability - investment in APLNG There is an unrecognised deferred tax liability in respect of our investment in APLNG because the accounting cost base of the investment is higher than the tax cost base. The accounting carrying value has been augmented, primarily as a result of our equity accounted share of retained profits to date, while the tax cost base reflects only the cash outlaid. Consistent with accounting standards, the deferred tax liability has not been recognised historically because 1. Origin is able to control the timing of distributions from APLNG which would reverse the temporary difference; and 2. It has not been probable that the temporary difference will reverse in the foreseeable future via dividends paid from current retained earnings, capital returns or a disposal. As it had become probable in FY2021 that APLNG would begin to distribute cash to shareholders via dividends in the coming years, Origin recognised a deferred tax liability. Recognition of the deferred tax liability only impacts the timing of accounting for the tax expense and has no impact on the underlying economics or cash flows. During the year, the unfranked ordinary dividends of $1,783 million were received from APLNG. The unfranked dividends received during the year were higher than our share of equity accounted income of $1,184 million, which means the excess has been paid out of prior year profits. The proportion paid from current year earnings gave rise to a tax expense of $355 million and the balance paid out of prior year profits resulted in the partial utilisation of previously recognised deferred tax liability of $180 million. As at 30 June 2023, we have a deferred tax liability on the balance sheet of $528 million, representing 30 per cent of the dividends expected to be paid by APLNG in the foreseeable future from the carried forward equity accounted earnings based on current market assumptions, including future oil prices, in respect of our interest of 27.5 per cent. There is a remaining unrecognised deferred tax liability at 30 June 2023 of $759 million which may be partly or fully recognised in the future. 2 Accounting for large-scale generation certificate trading strategy Supply and demand for large-scale generation certificates (LGCs) is driven by the rate of new renewable projects coming online, voluntary demand for carbon offsets as well as the compliance obligations under the Large-scale Renewable Energy Target (LRET). Renewable project delays and generation curtailments have led to a near-term tightening of the LGC market. However, it is expected that the 33 TWh legislated target will be exceeded and longer term the market will be oversupplied. The Clean Energy Regulator has acknowledged this and provides the option for parties to shift demand from periods of tight supply by deferring the surrender of certificates to later years. Under the scheme, parties can defer up to 10 per cent of their obligation at no additional cost and can defer more than 10 per cent by incurring a shortfall charge of $65 per certificate that is refundable provided the LGCs are surrendered within three years. Refunds are now non-assessable for tax following legislative change and aligns with the non-deductible treatment of the shortfall charge. This presents an economic opportunity with the LGC forward curve in backwardation and Origin has elected to defer surrender of 2.5 million CY2020 certificates in February 2021, 3.6 million CY2021 certificates in February 2022, and 3.2 million CY2022 certificates in February 2023. During FY2023, a shortfall charge of $206 million was paid in relation to CY2022 certificates of which $92 million was accrued in FY2022. Included in the FY2023 Underlying Profit is a cost of $38 million, reflecting the estimated future surrender cost, based on a weighted average of the current forward price and purchases to date, comprising: • • 1.4 million CY2022 certificates recorded in FY2022 repriced from $14 to $18; 1.8 million CY2022 certificates at $18 per certificate. The balance of $76 million is excluded from Underlying Profit. Over FY2024 to FY2026 we will receive a net cash refund of $425 million, representing the shortfall charge paid less the actual cost of the certificates: • $114 million in FY2024; • $163 million in FY2025; • $148 million in FY2026.

Non-executive Directors are eligible to participate in the Non-executive Director Share Plan (NEDSP) which is a fee sacrifice plan. During the year, one allocation and vesting of Rights occurred as a result of a Non-executive Director electing to participate in the NEDSP in FY22. No new participants entered the NEDSP and no further fees sacrifice was made by the existing participant in FY23. The following securities were granted to the five most highly remunerated officers (other than Directors) of the Company during the year ended 30 June 2023: J Briskin G Jarvis A Lucas A Thornton L Tremaine Performance Share Rights (PSR) over ordinary shares Restricted Share Rights (RSR) over ordinary shares 65,002 65,748 61,067 61,883 73,281 65,004 65,751 61,068 61,881 73,281 Restricted Shares 90,819 93,268 61,348 100,836 110,146 Matching Share Plan Rights1 Employee Share Plan Shares 367 367 - 367 367 - - 161 - - 1 Matching Share Plan Rights were granted in accordance with the Employee Share Plan rules and disclosed to the ASX at the time of grant. The Employee Share Plan is available to all eligible Origin employees. The Managing Director and Chief Executive Officer is not eligible to participate in the Employee Share Plan. The Employee Share Plan was suspended from 1 April 2023. Refer to Section 3.7 of the Remuneration Report for further details. The awards of Restricted Shares, Performance Share Rights, and Restricted Share Rights were made in accordance with the Company’s Equity Incentive Plan as part of the relevant Executive’s remuneration. Further details on Rights granted during the financial year, and unissued shares under Rights, are included in Section 7 of the Remuneration Report. No Options or Rights were granted since the end of the financial year. Origin shares issued on the exercise of Options and Rights Options No Options granted under the Equity Incentive Plan were exercised during or since the year ended 30 June 2023, so no ordinary shares in Origin were issued as a result. Rights 814,297 ordinary shares of Origin were allocated from the Origin Energy Limited Employee Share Trust during the year ended 30 June 2023 on the vesting and exercise of PSRs under the Equity Incentive Plan, vesting and exercise of Matching Share Plan Rights granted under the Employee Share Plan and vesting and exercising of Rights under the Non-executive Director Share Plan. No amounts were payable on the vesting of these PSRs and Matching Share Plan Rights and, accordingly, no amounts remain unpaid in respect of any of those shares. Since 30 June 2023, 3,389 ordinary shares were allocated from the Origin Energy Limited Employee Share Trust on the vesting of Matching Share Plan Rights granted under the Employee Share Plan. All shares in the Origin Energy Limited Employee Share Trust were purchased on market. 7 Environmental regulation and performance The Company’s operations are subject to environmental regulation under Commonwealth, State and Territory legislation. For the year ended 30 June 2023, the Company notified 24 environmental reportable incidents to the relevant regulators (Integrated Gas: 13 and Energy Supply and Operations: 11). All of these incidents resulted in minor environmental consequences with the appropriate level of investigation undertaken. All incidents are investigated, and lessons learned captured and shared across the Company. Integrated Gas received one Formal Warning Letter and three Compliance Notices because of these incidents. During the year ended 30 June 2023, Integrated Gas received two Prosecutions, one Penalty Infringement Notice, one Formal Warning Letter and three Compliance Notices from the Department of Environmental Science and Department of Resources in Queensland for previous incidents and other compliance related matters. Within Energy Supply and Operations there was one Formal Warning Letter received. Directors’ Report 57 8 Indemnities and insurance for 10 Non-audit services Directors and Officers Under its Constitution, the Company may indemnify current and past Directors and Officers for losses or liabilities incurred by them as a Director or Officer of the Company or its related bodies corporate to the extent allowed under law. The Constitution also permits the Company to purchase and maintain a Directors’ and Officers’ insurance policy. No indemnity has been granted to an auditor of the Company in their capacity as auditor of the Company. The Company has entered into agreements with current Directors and certain former Directors whereby it will indemnify those Directors from all losses or liabilities in accordance with the terms of, and subject to the limits set by, the Constitution. The agreements stipulate that the Company will meet the full amount of any such liability, including costs and expenses to the extent allowed under law. The Company is not aware of any liability having arisen, and no claim has been made against the Company during or since the year ended 30 June 2023 under these agreements. During the year, the Company has paid insurance premiums in respect of Directors’ and Officers’ liability, and legal expense insurance contracts for the year ended 30 June 2023. The insurance contracts insure against certain liability (subject to exclusions) of persons who are or have been Directors or Officers of the Company and its controlled entities. A condition of the contracts is that the nature of the liability indemnified and the premium payable not be disclosed. 9 Auditor independence There is no former partner or director of EY, the Company’s auditors, who is or was at any time during the year ended 30 June 2023 an officer of the Origin Energy Group. The auditor’s independence declaration for the financial year (made under section 307C of the Corporations Act 2001 (Cth)) is attached to and forms part of this Report. The amounts paid or payable to EY for non-audit services provided during the year was $840,000 (shown to the nearest thousand dollars). Amounts paid to EY are included in note G7 to the full financial statements. Based on written advice received from the Audit Committee Chair pursuant to a resolution passed by the Audit Committee, the Board has formed the view that the provision of those non-audit services by EY is compatible with, and did not compromise, the general standards of independence for auditors imposed by the Corporations Act 2001 (Cth). The Board’s reasons for concluding that the non-audit services provided by EY did not compromise its independence are: • all non-audit services provided were subjected to the Company’s corporate governance procedures and were either below the pre- approved limits imposed by the Audit Committee or separately approved by the Audit Committee; • all non-audit services provided did not, and do not, undermine the general principles relating to auditor independence as they did not involve reviewing or auditing the auditor’s own work, acting in a management or decision making capacity for the Company, acting as an advocate for the Company or jointly sharing risks and rewards; and • there were no known conflict of interest situations nor any other circumstance arising out of a relationship between Origin (including its Directors and Officers) and EY which may impact on auditor independence. 11 Proceedings on behalf of the Company The Company is not aware of any proceedings being brought on behalf of the Company, nor any applications having been made in respect of the Company under section 237 of the Corporations Act 2001 (Cth). 12 Rounding of amounts The Company is of a kind referred to in ASIC Corporations (Rounding in Financial/ Directors’ Reports) Instrument 2016/191 dated 24 March 2016 and, in accordance with that class order, amounts in the financial report and Directors’ Report have been rounded off to the nearest million dollars unless otherwise stated. 13 Remuneration The Remuneration Report forms part of this Directors’ Report. 58 Annual Report 2023 Remuneration Report For the year ended 30 June 2023 The Remuneration Report for the year ended 30 June 2023 (FY2023) forms part of the Directors’ Report. It has been prepared in accordance with the Corporations Act 2001 (Cth) (the Act) and Accounting Standards, audited as required by section 308(3C) of the Act. Letter from the Chairman of the Remuneration, People and Culture Committee Dear Shareholder On behalf of the Remuneration, People and Culture Committee (RPCC) and the Board, I am pleased to present the Remuneration Report for FY2023. The Company has delivered strong results in a year characterised by extraordinary volatility of commodity prices in the early part of the year and a changing regulatory environment. The results were driven by a recovery in earnings from Energy Markets and higher contributions from Octopus Energy and Integrated Gas. Energy Markets earnings increased as higher wholesale prices flowed into customer tariffs. Octopus Energy earnings increased due to the growth in retail customer accounts and the reset of regulated tariffs in the UK. In Integrated Gas, higher global oil prices resulted in record revenue for Australia Pacific LNG during the period. Throughout the year, the management team maintained its focus on executing the clear strategies to lead the energy transition, managing risks and ensuring reliable supply. FY2023 remuneration outcomes As foreshadowed in the FY2022 Remuneration Report, following comprehensive benchmarking the Fixed Remuneration (FR) of the CEO was increased by 4.0 per cent at the start of FY2023. The FR of other Executive Key Management Personnel (KMP) increased by an average of 3.5 per cent, which is slightly less than adjustments applied to staff across the organisation more generally. There were no changes to the variable pay structure or opportunity levels for executives in FY2023. Details regarding the Short Term Incentive Plan (STIP) and Long Term Incentive Plan (LTIP) variable pay arrangements are provided in Sections 3.4 and 3.5 respectively. Remuneration outcomes reflected the strength of operational and financial performance. In summary: • Scorecard outcomes for the Short Term Incentive Plan (STIP) were 75.3 per cent of the maximum for the CEO, and ranged from 74.0 per cent to 90.2 per cent of the maximum for Other Executive KMP. The aggregate Executive KMP outcome was 79.3 per cent of the maximum, reflecting the solid results for the year. Further details are provided in Sections 4.2.1 to 4.2.3. • Long Term Incentive (LTI) awards tested during the year vested partially (16.0 per cent), based on the outcomes of four separate tests on awards that were granted in the calendar years 2017 and 2019. Full details are provided in Section 4.2.4. Partial vests for each of the last three years (following eight years of consecutive zero vests) reflect recent improvements in Return on Capital Employed (ROCE) performance, and (as noted below) recent improvements in Total Shareholder Return (TSR) will be reflected in full LTIP vesting during FY2024. These trends reflect consistent and strong improvements in long-term performance over the last four years. On 9 November 2022, the Company received an indicative, conditional and non-binding proposal from a Consortium consisting of Brookfield and MidOcean Energy (an LNG company managed by EIG) to acquire all the issued shares in the Company by way of a scheme of arrangement and on 27 March 2023 executed a binding Scheme Implementation Deed (SID) in relation to the proposed scheme of arrangement (Scheme). The Scheme remains subject to various conditions, including that Origin shareholders approve it at a meeting of shareholders and that it receives court and regulatory approvals. Following receipt of the proposal, targeted retention arrangements were put in place during December 2022 that covered 232 employees (at a conditional total value of $17 million) deemed critical to continuing safe operations, including one member of the Executive KMP. See Section 3.7 for more details. Remuneration for FY2024 Each year, the RPCC considers the remuneration framework’s continuing appropriateness in terms of Origin’s strategies and priorities. It also considers the framework’s effectiveness and capacity to provide realisable remuneration that attracts and keeps the right people, drives their focus and rewards execution. While the Board concluded this year that the current framework and policy settings remain balanced and appropriate, the operation of the equity components of the STIP and LTIP has been impacted by the execution of the SID. Remuneration arrangements relating to the Scheme will be set out in a separate scheme booklet that will be provided to shareholders at the appropriate time. However, some changes to Origin’s remuneration approach for FY2024 were also necessary because of the proposed Scheme. Since the proposal was announced, Origin’s share price has become reflective of the proposed bid price. This impacts the assessment of performance, particularly in relation to the use of a Relative TSR hurdle, which has been used historically within Origin’s LTIP. Further, the Scheme requires that no equity incentives (including share rights and restricted shares) remain on foot after implementation of the Scheme, and the usual performance and deferral periods associated with Origin’s equity incentives are beyond the likely timing of the proposed Scheme. Accordingly, the Board has approved the following changes: • Deferred STI – the FY2023 Deferred STI award (to be granted in September 2023) will be made in the form of Deferred Cash, subject to the usual deferral periods. See Section 3.4 for further details. • LTIP – the LTIP award (also to be granted in September 2023) will be made in the form of Deferred Cash, subject to a three-year deferral. Further, it will be granted at a level equivalent to 75 per cent of the current opportunity level. It will also be subject to financial and non-financial underpin conditions. See Section 3.5 for more details. There are no other changes planned to the remuneration framework for FY2024. Remuneration Report 59 There will be no changes to the structure or level of Non-executive Directors (NED) fees for FY2024. Increases to FR in FY2024 for Executive KMP will be around 4.0 per cent, which is in line with employees from the wider organisation who participate in annual market reviews. This includes the legislated increase to the Superannuation Guarantee Levy effective from 1 July 2023 and is consistent with prevailing market movements, economic conditions and benchmarks. LTI vests that will occur during FY2024 include those for awards granted in November 2020. These awards will vest in full commencing at the end of August 2023. Further details are provided in Section 4.2.4. The Board’s view is that the remuneration outcomes over the last few years have appropriately aligned with business performance and shareholder experience, as intended by the remuneration framework design.

Remuneration Report 61 2 Remuneration link with Company performance and strategy 2.1 Overview of remuneration framework Our remuneration framework is designed to support the Company’s strategy and to reward our people for its successful execution. It is designed around three principles, which are summarised in the following table. Principles and purpose Process Delivery and timeline Remuneration component Fixed Remuneration (FR) Short Term Incentive Plan (STIP) To attract and retain the right people and pay fairly and competitively. Takes into account the size and complexity of the role, and the skills and experience required for success in the role. All market-remunerated roles are benchmarked at least annually to the median (between P40 and P60) of corresponding roles in organisations with comparable activity and scale, and with which Origin competes for talent. To drive focus and discretionary effort. Performance is tested at the end of a one-year performance period. It is measured and assessed against a balanced scorecard, usually comprising up to 10 metrics (accounting for 60% financial and 40% strategic priorities), each with targets set at threshold, expected (target) and stretch (maximum) levels. The overall scorecard outcome for each participant determines the proportion of the opportunity that will be paid (up to a maximum of 100% of the executive’s opportunity level). Threshold performance scores 20% of stretch, and target is defined as 60% of stretch (i.e. stretch is 167% of target). For Executive KMP, the maximum opportunity level is equivalent to 167% of FR (or 100% FR at target). For other members of the ELT, the maximum is 125% FR (or 75% FR at target). Results are subject to Board overview and discretion to adjust formulaic outcomes up (but no higher than the opportunity level) or down (including to zero). Annual grants are made to executives based on their capacity to influence long-term outcomes. The awards are granted at the beginning of a three- year performance period, and may be deferred for up to five years (inclusive of the three-year performance period). For the CEO, the unrisked face value of the grant is equivalent to 120% FR, with a risked value1 of 90% FR. For Other Executive KMP and other members of the ELT, the unrisked face value is 80% (risked value 60% FR). Cash salaries, employer contributions to superannuation and salary sacrifice benefits paid continuously throughout each year. Awarded annually; 50% in cash payable in September following the end of the financial year, and 50% deferred for two years following the cash payment. Deferred elements awarded in August– September 2022 (in respect of FY2022 performance) were in the form of Restricted Shares (restricted for two years). The whole of the STI award is forfeited for resignation/cause prior to payment, the deferred element is forfeited for resignation/cause prior to release, and both elements are subject to clawback. For FY2024 only: Deferred elements to be granted in August–September 2023 (in respect of FY2023 performance) will be in the form of Deferred Cash to be paid in August 2025. For awards made in August–October 2022, the award was made at the unrisked face value (120% FR for the CEO and 80% FR for Other Executive KMP). One half was made conditional on Relative TSR performance (delivered in the form of Performance Share Rights (PSRs), vesting at the end of the performance period) and the other half on a suite of underpinning metrics (delivered in the form of Restricted Share Rights, vesting over three to five years). Vested rights were allocated into Restricted Shares, with total deferrals (including performance period) of five years. Awards are forfeited for pre-vest resignation/cause and subject to post-vest clawback. For FY2024 only: For awards to be made in August–September 2023, the award will be made at the risked value1 (90% FR for the CEO and 60% FR for other executives), conditional on a suite of underpinning metrics over FY2024, FY2025 and FY2026, and is to be paid in the form of Deferred Cash in August 2026. n o i t a r e n u m e R e b a i r a V l Long Term Incentive Plan (LTIP) ) R V ( To encourage focus on long-term performance and sustainability, and to build executive share ownership in the business. 1 See Section 3.2 for an explanation of risked value. 62 Annual Report 2023 2.2 Board oversight Remuneration outcomes are subject to Board oversight and strong governance controls, as set out in Section 5.3. Origin believes that observance of its values and leadership behaviours, and the quality of its relationships with its customers and the community, are inextricably linked to the creation of shareholder value. Prior to making remuneration determinations, the full Board conducts formal reviews of management that incorporate individual performance, risk management and leadership behaviours. The Board may adjust variable outcomes up or down. 2.3 Minimum Shareholding Requirement for Executive Key Management Personnel A key objective of the remuneration framework is to promote employee share ownership and to encourage employees to think and act as owners. Equity is therefore a key element of remuneration, representing half of STI awards and the whole of LTI awards. This is supplemented by other share plan arrangements, including salary sacrifice, share purchase and matching plans (see Section 3.7). Executive KMP are required to build and maintain a substantial shareholding in the Company (that is, the Minimum Shareholding Requirement (MSR)). Executives are not expected to purchase shares to meet the requirement. The MSR operates as an additional trading restriction, which prevents the disposal of shares that have been generated from executive share plans (other than to cover arising tax liabilities) until the MSR has been achieved and maintained. The requirement would normally be achieved within four years of the first equity grant following appointment. The MSR is referenced to one of two nominal multiples of FR, one for the CEO and one applicable to all Other Executive KMP. Following changes to the LTIP in August 2020, the reference multiples are scheduled to increase from 200 per cent of the FR to 250 per cent of the FR for the CEO, and from 100 per cent to 150 per cent of the FR for Other Executive KMP. The scheduled increase will be effective after August 2023, which is the earliest date the new plan can begin to impact vesting patterns. For transparency, simplicity and practicability,1 the MSR is expressed as a number of shares rather than a dollar value. From time to time, the Board changes this number, which is determined by taking into account changes in FR, changes to STI deferral or LTI opportunity levels, and the medium-term share price trend. The current determinations of 620,000 shares (CEO) and 130,000 shares (Other Executive KMP) are scheduled to increase to 720,000 and 160,000, respectively, in 2024. Share rights awarded under incentive plans do not count towards the MSR obligation. Table 7.4 (a) shows that the CEO and Executive KMP exceed both the current and FY2024 MSR requirements. 1 A practical consideration is that Executives periodically need to sell shares to meet Employee Share Scheme tax obligations. Any process of tagging shares for MSR according to the share price of specific shares at grant or allocation (for example) would become exceedingly complex to track when parcels are disposed of according to other tags (such as cost bases for capital gains tax purposes). Remuneration Report 63 3 Remuneration framework details 3.1 Fixed Remuneration FR comprises cash salary, employer contributions to superannuation and salary sacrifice benefits. It takes into account the size and complexity of the role, and the skills and experience required for success in the role. FR is reviewed annually, but increases are not guaranteed. Roles are benchmarked to the median of corresponding roles in organisations with comparable activity and scale, and with which Origin competes for talent.2 In the absence of special factors, new or newly promoted incumbents generally commence below this reference point and move to the median over time. FR may be positioned above this reference point where it is appropriate to reward sustained high performance, for key talent retention or where it is necessary to attract and secure key skills to fill a business-critical role. Accordingly, the individual positioning may vary between approximately the 40th and 60th percentile of the reference market. 3.2 Variable Remuneration Variable Remuneration (VR) enables pay to be adjusted upwards or downwards, depending on whether performance outcomes exceed or fall short of expectations. Unlike bonus systems that pay for performance above expectations but do not reduce pay where performance falls short, VR does both. It is important to note that the total of FR plus VR is set and benchmarked such that the at target outcome represents the satisfaction of expected performance. VR comprises the total of STI and LTI: • The minimum VR is zero, where no STI or LTI is awarded, or where the STI scorecard outcome is zero and LTI is not awarded or all of it fails to vest, or where discretion is exercised to reduce such awards or vesting outcomes to zero. • The target VR represents the total of STI when it is awarded at the target level (60 per cent of maximum), plus the risked value of LTI of the share rights awarded at face value3 (the present-day value of the probabilistic vesting outcome). The risked value of the Performance Share Rights (PSRs) subject to a Relative TSR performance condition is 50 per cent of face value (supported by actuarial grant date valuations over time). The risked value of Restricted Share Rights (RSRs) is considered for this purpose to be 100 per cent of face value. With the same number of rights awarded equally, the overall risked value is therefore 75 per cent of the face value. Accordingly, Target VR = (STI at 60 per cent of maximum) + (LTI at 75 per cent of face value allocation). • The maximum VR is the total of STI awarded at the maximum level, plus the full face value of all LTI assuming 100 per cent vesting. VR outcomes are subject to Board oversight and discretionary adjustment, as summarised in Sections 4.2 and 5.3. For LTI grants in FY2024 only, the LTI allocation will be granted in Deferred Cash rather than share rights. Accordingly it will be granted at 75 per cent of the level at which it would have been made had it been granted in the form of share rights. In this instance, the maximum LTI value is reduced to, and is the same as, the target LTI value. 3.3 Total Remuneration Total Remuneration (TR) is the sum of FR and VR. TR at target (TRT) TR maximum (TRM) = = FR FR + + target VR maximum VR TRT is benchmarked to the median of equivalent TRT in the reference market, with the intention that when Origin’s outcomes are at their maximum possible (that is, TRM), they will be comparable to the top quartile of the reference TRT. 2 The prime reference is to ASX-listed organisations ranked between seven and 70 by average two-year market capitalisation (excluding foreign domiciles, listed investment companies or similar), always including AGL, APA Group, Santos and Woodside. 3 The face value at the date of grant is represented by the share price on the date of grant. The face value of deferred equity elements (Deferred STI and LTI) is represented by the current share price (present-day value) because it is not possible to predict future share prices. 64 Annual Report 2023 3.4 FY2023 Short Term Incentive Plan details The following is a detailed description of the operation of the STIP. Parameter Award basis Details The annual performance cycle is 1 July to 30 June. Individual balanced scorecards are agreed, with shared Group objectives and targeted divisional objectives. Objectives are set across financial categories (generally 60 per cent of the weightings) and non-financial categories (generally 40 per cent). The CEO’s FY2023 scorecard details and outcomes are shown in Section 4.2. Scorecard operation Individual objectives on the scorecard are referenced to three performance levels: threshold, target and stretch (with pro-rating between each). Threshold performance represents the lower limit of rewardable outcome for an individual objective – one that represents a satisfactory outcome, often achieving year-on-year improvement and contribution towards delivery of annual plans, but falling short of the target level. Threshold performance yields 20 per cent of the maximum (33 per cent of target). Target represents the expectation for achieving robust annual plans, yielding 60 per cent of the maximum. Stretch performance represents the delivery of exceptional outcomes well above expectations, yielding the maximum payout (corresponding to 167 per cent of target). Opportunity level Award calculation and assessment Delivery and timing RS allocation Service conditions and cessation of employment The opportunity level for FY2023 for all Executive KMP was unchanged at 100 per cent FR at target, with a capped maximum of 167 per cent of FR. Achievement and performance against each Executive’s balanced scorecard is assessed annually as part of the Company’s broader performance review process and is subject to Board oversight and adjustment as detailed in Sections 2.2 and 5.3. The STI award is delivered in two parts, a cash element and a deferred element, each representing half of the award. Both elements are delivered shortly after the end of the financial year to which they relate. The deferred element is delivered in the form of Restricted Shares (RSs), that are restricted for two years. The award is subject to forfeiture if the service conditions are not met (as set out below). For deferred awards to be granted in FY2024 only (noting that these awards relate to FY2023 performance), the deferred element will be delivered in the form of Deferred Cash, deferred for two years (until July 2025). Where the deferred element is granted in the form of RSs, the number of RSs = Deferred STI amount divided by the 30-day volume-weighted average price (VWAP) to 30 June of the performance year just completed, rounded to the nearest whole number. Unless the Board determines otherwise: • For resignation or dismissal with cause, the whole of an STI award is forfeited. Deferred elements from prior awards that are within their restriction or deferral period are also forfeited. • In cases of death, disability, redundancy or genuine retirement (good leaver circumstances), to the extent that an STI award is payable, it is delivered wholly in cash. Deferred elements from prior awards that are within their restriction or deferral period remain on foot until the end of their restriction or deferral period. Dividends As the STI has been earned and awarded, RSs carry dividend entitlements and voting rights. Remuneration Report 65 Parameter Sourcing of RSs Details The Board’s practice is to purchase shares on market, but it may issue shares or make the award in alternative forms, including Deferred Cash. Governance and MSR After restrictions on RSs are lifted, trading is subject to the MSR (see Section 2.3), the Company’s Dealing in Securities Policy, and to the malus and clawback provisions in Section 5.3. 3.5 FY2023 Long Term Incentive Plan details The following is a detailed description of the operation of the LTIP. Parameter Award basis Opportunity and value range Details LTIP awards are conditional grants of equity that may vest in the future, subject to the meeting of performance conditions and/or underpinning criteria, and subject also to the Executive meeting service and personal conduct and performance requirements. Awards are considered annually for approximately 75 senior roles that have significant influence on long-term company performance. The LTIP opportunity level reflects the capacity of the role to influence long-term sustainable growth and performance, and is set with reference to market benchmarks (see Section 3.2). Opportunity levels are expressed as a percentage of FR (at the commencement of the financial year in which the grant is to be made) and in terms of the total face value of the awards (that is, not discounted for risk). LTIP opportunity (percentage of FR) Executive KMP Minimum Maximum CEO Other 0 0 120 80 Awards are granted at face value. The Board may determine that the allocation should be varied up or down; however, in the normal course of events awards are granted at the maximum opportunity level (given that they are subject to future performance and underpinning conditions, and are also subject to malus and clawback processes). The value of an award is as follows: • The minimum value is zero (which will be the case if the award fails to vest, is forfeited or is not awarded). • The target value represents the risked or expected value of the maximum grant, taking into account the likelihood of vesting (see Section 3.2). • The maximum value represents the present-day face value of the maximum grant, assuming that 100 per cent of the grant vests, ignoring the risks of achieving performance conditions and of the service requirements. The actual or realised value of an LTIP award depends on the level of vesting and the share price at the time of vesting, neither of which can be determined in advance. LTIP awards are delivered in the form of share rights. The share rights do not carry any dividend or voting entitlements. Each vested share right represents a right to a fully paid ordinary share (as an RS) in the Company and such additional shares equal to the value of dividends (as determined by the Board) in the period from grant to exercise on the underlying share on a reinvested basis. The terms and conditions applying to the share rights or RSs also apply to the dividend-equivalent amounts and shares. The Board retains a discretion to make a cash equivalent payment to settle the dividend-equivalent amount in lieu of an allocation of shares. The share rights are granted at no cost because they are awarded as remuneration. No dividend or dividend-equivalents are received by participants on share rights during a vesting period, and none are received on share rights that do not vest. Shares allocated upon vesting of rights (including rights to a dividend- equivalent amount) carry the same dividend and voting rights as other shares (including while they are subject to a holding lock). Vehicle, dividends and voting rights Number and type of share rights The total number of share rights to be granted is calculated by taking the face value of the award being made and dividing it by the 30-day VWAP of Origin shares to 30 June preceding the grant, rounded to the nearest whole number. The award is divided into two halves, each with its own vesting conditions. One half of the share rights is awarded as PSRs that are subject to a Relative TSR (RTSR) performance condition with a conventional vesting scale. The other half of the share rights is awarded as RSRs where vesting is subject to Board discretion with reference to a suite of underpinning conditions as described below. The number of RSRs will be divisible by three because this tranche is further divided into three equal parts, which vest progressively as described below. 66 Annual Report 2023 Parameter Details Vesting and release All of the share rights are deferred for five years. PSR tranche RSR tranche The PSR tranche vests (subject to achievement against the RTSR vesting scale) into RSs at the end of the three-year performance period, remaining under a holding lock for a further two years. The RSR tranche vests (subject to Board discretion) progressively after three, four and five years. The part that vests after three years is into RSs that remain under a two-year holding lock; the part vesting after four years is locked for a further year; and the final part vests after five years into unrestricted shares. The vesting dates corresponding to the three-year, four-year and five-year periods are determined as the second trading day after the release of the respective full-year results. For awards granted in September and October 2022, these are expected to be 26 August 2025, 25 August 2026 and 24 August 2027 (Release Date). At all times before and after vesting, and after release from a holding lock, the share rights and shares remain subject to malus and clawback provisions (Section 5.3). They may also be subject to trading restrictions arising from the MSR (see Section 2.3) and from the Company’s Dealing in Securities Policy. RTSR measures the Company’s TSR performance relative to a reference group of companies, assuming reinvestment of dividends, measured over three financial years with vesting deferred for a further two years. It has been chosen because it aligns Executive reward with shareholder returns. It rewards only when Origin outperforms the reference group; it does not reward overall market uplifts. The market reference group is the S&P/ASX 50,1 representing a transparent and widely understood group of companies with which Origin competes for investors, skills and talent. Narrower comparator groups have not been chosen due to the small number of companies with investment profiles and operations similar to those of Origin. In calculating RTSR, share prices are determined using three-month VWAPs to the start and end of the performance period. Vesting occurs only if Origin’s TSR over the performance period ranks it higher than the 50th percentile of the group. Half of the PSRs vest on satisfying that condition, and all of the PSRs vest if Origin ranks at or above the 75th percentile. Straight-line pro-rata vesting applies between these two points. In contrast to the PSR tranche, which is conditional on performance against a single external financial metric, the RSR tranche is designed to vest in full unless there is a material deviation from Board expectations of performance across approximately 30 key metrics. These metrics reflect the underlying health, performance and sustainability of the Company and, since FY2021, are reported annually as the Key Sustainability Performance Measures in the Company's annual Sustainability Report. They cover the four dimensions of Customer, Community, Planet (climate change and environment) and People. If, at the review date for vesting, the Board considers management’s performance against the totality of these underpinning indicators has not met its expectations, then it may reduce or cancel vesting accordingly. Together, the PSR and RSR tranches provide a balance that incorporates a hard, single financial test with a holistic assessment across the full range of performance areas that will position the Company for ongoing success. This approach aligns management interests with those of shareholders and stakeholders by building Executive share ownership and driving focus across the full range of key measures that align operations with long-term strategy. The RSR vesting review process incorporates outcomes from the Executive Performance Review (described in Section 5.3) and overall performance with reference to the underpinning indicators, in addition to risk and reputation matters. Vesting decisions will be disclosed in the relevant Remuneration Report accompanied by a rationale for the Board’s determinations. Service conditions and cessation of employment Unless the Board determines otherwise: • For resignation or dismissal with cause, all share rights are forfeited. Sourcing Arrangements for FY2024 only • In cases of death, disability, redundancy or genuine retirement (good leaver circumstances), share rights remain on foot subject to their original terms and conditions (other than the continuing service condition). The Board’s preferred approach is to satisfy the vesting of share rights through the purchase of shares on market, but it may issue shares or make the award in alternative forms, including cash or deferred cash. LTI awards to be made in August–October 2023 will be in the form of Deferred Cash, as noted in the RPCC Chairman’s introductory letter to this report. As noted in Section 3.2, the allocations will be at the target (risked) opportunity level. For the CEO, this will be at 90% FR (instead of 120%), and for Other Executive KMP at 60% FR (instead of 80% FR). The previous financial metric (Relative TSR) is not practicable in the current market circumstances. Accordingly, for FY2024 only, the underpin arrangements that have previously applied to non-financial metrics will be extended to apply to financial metrics. These awards will have a simple three-year vesting period, recognising that the rationale for further exposure to long-term share price movement has been altered, and that the FY2024 award focus is on retention in the early post-transaction phase. 1 The TSR reference group is set at the commencement of the performance period. For FY2023, it comprised: Aristocrat Leisure Ltd, Amcor Plc, Australia and New Zealand Banking Group Ltd, APA Group, ASX Ltd, BHP Group Ltd, Bluescope Steel Ltd, Brambles Ltd, Commonwealth Bank Of Australia, Cochlear Ltd, Coles Group Ltd, Computershare Limited, CSL Ltd, Dexus, Endeavour Group Ltd, Fortescue Metals Group Ltd, Goodman Group, GPT Group, Insurance Australia Group Ltd, James Hardie Industries Plc, Lendlease Group, Mirvac Group, Mineral Resources Ltd, Medibank Private Ltd, Macquarie Group Ltd, National Australia Bank Ltd, Newcrest Mining Ltd, Northern Star Resources Ltd, Qantas Airways Ltd, QBE Insurance Group Ltd, Ramsay Health Care Ltd, Rio Tinto Ltd, Resmed Inc, South32 Ltd, Scentre Group, Seek Ltd, Stockland Corporation Ltd, Sonic Healthcare Ltd, Santos Ltd, Suncorp Group Ltd, Transurban Group, Lottery Corporation Ltd, Telstra Corporation Ltd, Treasury Wine Estates Ltd, Westpac Banking Corp, Woodside Energy Group Ltd, Wesfarmers Ltd, Woolworths Group Ltd, and Xero Ltd. Remuneration Report 67 3.6 Remuneration range and mix The potential range for the CEO’s total remuneration in FY2023 was between a minimum of $1.95 million (his FR) to a target of $5.671 million and a maximum of $7.565 million (FY2022: $7.276 million). The remuneration mix at target and at maximum is shown in the table below, which shows the significant proportion of variable or performance-based pay and delivery in equity. Variable or performance-based pay represents 65.5 per cent of the CEO’s package at target outcomes, and 74.2 per cent at maximum outcomes. Forfeitable equity represents 48.3 per cent at target outcomes and 52.6 per cent at maximum outcomes.

Under the $1,000 scheme (the General Employee Share Plan (GESP)), shares are restricted for three years or until cessation of employment, whichever occurs first. Under the Matching Share Plan (MSP), shares purchased under the sacrifice scheme are restricted for two years or until cessation of employment, whichever occurs first. For every two shares purchased under the salary sacrifice scheme within a 12-month cycle, participants are granted one Matching Right (MR) at no cost. The MRs vest two years after the cycle began, provided that the participant remains employed by the Company at this time. Each MR entitles the participant to one fully paid ordinary share in the Company, or in certain limited circumstances a cash equivalent payment. The MRs do not have any performance hurdles as they have been granted to encourage broad participation in the scheme across the Company, and to encourage employee share ownership. All shares are currently purchased on market. Directors are not eligible to participate in the above schemes, but may participate in the NED Share Plan (NEDSP) by sacrificing Board fees. This plan is intended to facilitate share acquisition, enabling new Directors to meet their MSR obligations. All NEDs currently meet their MSR or are recently appointed. In FY2023, there was one participant who received an allocation of shares under the plan. Directors regularly assess the risk of the Company losing high-performing key people who manage core activities or have skills that are being actively solicited in the market. Where appropriate, the Board may consider the selected use of deferred payment arrangements to reduce the risk of such critical loss. From time to time, it may be necessary to offer sign-on equity to offset or mirror unvested equity, which a prospective executive must forfeit to take up employment with Origin. Following the receipt on 9 November 2022 of an indicative, conditional and non-binding proposal from the Consortium consisting of Brookfield and MidOcean Energy to acquire all the issued shares in Origin by way of a scheme of arrangement, targeted retention arrangements (valued at $17 million) were put in place in December 2022 that covered 232 employees who were deemed critical to continuing safe operations. These arrangements focused on operational roles, especially those ineligible for Deferred STI and LTI participation, which afford ongoing retention value. However, one member of the Executive KMP (Executive General Manager, Integrated Gas) was included due to the unique characteristics of the proposed transaction and the criticality of stewardship in the period ahead (refer to the disclosure in statutory table 7-2 (a)). The operation of the share plans has been suspended and no awards are expected to be made under them during FY2024. 68 Annual Report 2023 4 Company performance and remuneration outcomes This section summarises remuneration outcomes for FY2023 and provides commentary on their alignment with Company outcomes. 4.1 Five-year Company performance and remuneration outcomes The table below summarises key financial and non-financial performance for the Company from FY2019 to FY2023, grouped and compared with short-term and long-term remuneration outcomes.

In line with market practice, it includes the CEO. CEO-2 includes roles directly reporting to CEO-1. ‘Senior leadership roles’ captures the three reporting levels below CEO and includes roles with base salaries exceeding approximately $200,000 per annum. 6 Until FY2022, employee engagement was measured as an annual score obtained from a single independent survey conducted externally. Commencing in FY2023, employee engagement is measured continuously through the year through the OfficeVibe online tool. 7 New methodology using OfficeVibe from FY2023. The score is out of 10. 8 This is the total dollar value of STI awarded for Executive KMP as a percentage of their total maximum STI. The percentage of STI forfeited is this amount subtracted from 100 per cent. 9 The opening share price for FY2019 was $10.03. 10 Dividends represent the interim plus final dividends determined for each financial year. For FY2023, this includes the final dividend determined on 17 August 2023 to be paid on 29 September 2023. The amounts physically paid within each financial year are 10.0 cents, 30.0 cents, 22.5 cents, 20.0 cents, and 33.0 cents respectively. 11 TSR calculations use the three-month VWAP share price to 30 June, reflecting the testing methodology for Relative TSR ranking. 12 Underlying ROCE is defined in the ‘Glossary and Interpretation’ section. Underlying ROCE has been adjusted to exclude the impact of FY2022 $2.2 billion impairment of goodwill. Remuneration Report 69 4.2 Variable remuneration outcomes 4.2.1 Assessment process The Board has adopted governing principles to apply when considering adjustments to measures that are used for remuneration purposes. The starting points for setting STI scorecard targets are the relevant underlying measures from the financial accounts. Targets set at the beginning of the year may be subject to events materially outside the course of business and outside the control of the current management, in which case discretion may be required to vary targets or outcomes to reflect the intended purpose and/or actual results and achievements. The principles provide a structured process for the consideration of adjustments and the exercise of discretion, and a decision framework that seeks fairness (to both Executives and shareholders) and balance between favourable and unfavourable events. 70 Annual Report 2023 4.2.2 Short-term performance and Short Term Incentive outcomes STI awards are calculated on the basis of a balanced scorecard, with requirements set at threshold, target and stretch achievement levels. The CEO’s FY2023 scorecard, showing measures, outcomes and results, is summarised below.4 CEO FY2023 STI scorecard Measure, rationale and performance Origin Net Profit Before Tax (Origin NPBT) ($m) Measure of earnings and profitability The stretch result was driven by higher earnings from Energy Markets, Octopus Energy and Integrated Gas. Earnings from Energy Markets increased as higher wholesale prices flowed into customer tariffs. Earnings from Octopus Energy increased due to higher customer accounts and the reset of regulated tariffs in the UK. Earnings from Integrated Gas increased on higher commodity prices. Origin NCOIA ex Futures Collateral (Origin NCOIA) ($m) Measure of effective cashflow generation Higher earnings yielded stretch outcomes, notwithstanding unfavourable working capital movement. Energy Markets EBITDA (EM EBITDA) ($m)  Measure of operating performance of the Energy Markets business The same factors that contributed to the Origin NPBT outcome (without the Integrated Gas factors) drove the stretch result for the Energy Markets business. APLNG Lowest Cost of Supply ($m) Measure of capital and operating cost in the APLNG business  Financial measures Cumulative Scope 1 Emissions Reduction (CO2-e)(%) FY2021–2023 against 2017 SBTi Baseline Measure of progress against our decarbonisation strategy Shared key priorities To ensure alignment to strategic outcomes in the operational business the 'Shared key priorities' measure was introduced for FY2023. Shared key priorities includes measures, targets and outcomes connected to Retail X delivery, renewables, storage, Virtual Power Plant (VPP) and carbon objectives.

In addition, it reflects performance against the non-financial strategic priorities defined for the year (66.7 per cent of the maximum), accounting for the remaining 40 per cent of the STI award. The overall scorecard outcome was 75.3 per cent of the maximum (125.8 per cent of target). 4 The value for each of the three levels are shown along the top of the achievement bar and correspond to results of 20 per cent, 60 per cent or 100 per cent of the maximum, respectively. The actual achievement is represented by the darker shading along the bar, while the achievement value is recorded below the bar. Remuneration Report 71 Application of the principles described in Section 4.2.1 included the following: • The one-off and unplanned financial impacts of the sale of Beetaloo and Canning were excluded. • Penalties and legal costs associated with regulatory action excluded from underlying financial measures, were included for the purposes of calculating the relevant metrics. • The extremity of the La Niña weather events experienced during FY2023 had material impacts to the performance of APLNG beyond the control of management, adversely impacting the upstream operator’s ability to access well sites to perform drilling, workover and maintenance activities. The normal practice is not to make adjustments to remuneration metrics for weather events that are within the forecastable or experiential range; however, the extremity of the impacts this year was well outside that range. The Board determined that it would be appropriate to adjust for the atypical impact on this occasion. This affected the APLNG Production and Lowest Cost of Supply metrics. In making the determination the Board noted management’s exceptional responses to achieve rapid recovery. 4.2.3 Executive Key Management Personnel Short Term Incentive outcomes Origin’s NPBT and NCOIA targets, and therefore results, represent half of the financial metrics for all Executive KMP. The remaining financial metrics for divisional Executive General Managers are based on divisional targets. Accordingly, scorecard outcomes ranged between 74.0 per cent to 90.2 per cent of the maximum.

The strong operational annual performance is complemented by stabilisation and growth over the last five years, reflected in the return to partial LTI vesting in FY2021 following eight consecutive years of nil vesting. LTI awards partially vested (16.0 per cent) during FY2023. Testing involved four different performance measures. Options granted in the 2017 calendar year were conditional on Relative TSR (RTSR) performance over five years – as measured against a peer group of ‘ten-up/ten-down’ companies in terms of market capitalisation. Origin’s TSR performance over that period failed to exceed the 50th percentile ranking, therefore these awards lapsed. Half of the PSRs granted in the 2019 calendar year were conditional on RTSR performance over three years, as measured against the S&P/ASX 50 peer group. This award also failed to exceed the 50th percentile ranking in the peer group, therefore it also lapsed. The other half of the 2019 calendar year PSRs was conditional on ROCE performance over three years, measured separately in the Energy Markets and Integrated Gas business units (equally weighted). The target for Energy Markets was a three-year average ROCE (measured on an LTIP basis) of 9.24 per cent. With an actual average outcome of 4.32 per cent this component failed to vest and lapsed. The target for Integrated Gas was a three-year average ROCE of 7.09 per cent. The actual achieved was 9.03 per cent, which approached the stretch target of 9.09 per cent. Accordingly, this component vested at 98.5 per cent. The overall vesting outcome for executives depended on the relative levels of individual awards received by executives in the 2017 and 2019 calendar years. The overall average was 16.0 per cent. Awards that vested were settled in Restricted Shares (RSs) subject to an additional year of deferral (trading restriction). As identified in the Letter from the Chairman of the Remuneration, People and Culture Committee, LTI vests that will occur during FY2024 include those for awards granted in November 2020. These awards will vest in full commencing at the end of August 2023. Half of that grant was awarded as Performance Share Rights (PSRs) subject to a financial market condition (Relative TSR) vesting between 0 per cent and 100 per cent depending on Origin’s TSR over three years relative to the peer group (S&P/ASX-50). Origin’s TSR over the period was determined independently to be 74.04 per cent and at the 82.9th percentile of the peer group, resulting in 100 per cent vesting. The other half of the grant was awarded as RSRs which vest subject to the review process described in Section 3.5. At the end of the year the Board conducted an Executive Performance Review (summarised in Section 5.3), considering business and individual performance, risk assessment, together with a three-year lookback (FY2021–FY2023 inclusive) over a holistic suite of metrics reflecting the underlying health, performance and sustainability of its businesses and the Company overall. Following those reviews the Board determined that performance was strong and without material deviation from its expectations. Specific reference was made to the Key Sustainability Performance Measures reported in the Company’s Sustainability Reports. Following those reviews the Board determined full vesting for the RSRs. The PSRs vest into Restricted Shares with a two-year trading restriction, and the RSRs vest progressively (one third in August 2023, with a two-year holding lock, the next one-third in August 2024 with a one-year holding lock, and the final one-third is scheduled to vest in August 2025). The trend in long-term performance outcomes aligns with the long-term performance of the business and with shareholder experience. 72 Annual Report 2023 4.3 Total pay received in FY2023 In line with general market practice, a non-AASB presentation of actual pay received in FY2023 is provided below as a summary of real or take-home pay.

The value is determined as the number of shares vested or released multiplied by the five-day VWAP immediately prior to the date of vest/release. The amounts shown above relate to Restricted Share releases on 22 August 2022, arising from Deferred STI arrangements, plus GESP shares released on 5 September 2022 and Matching Share Plan Rights vested on 21 October 2022. 4 Long-term equity represents the value of previously awarded equity from long-term arrangements (LTIP and other arrangements with deferral periods of three or more years) that were released during FY2023. The value is determined in the same way as described in Note 3 above. The amounts shown all relate to releases on 22 August 2022 and 1 May 2023 (being three-year ROCE LTI awards and three-year restricted shares, respectively). Remuneration Report 73 5 Governance 5.1 The role of the Remuneration, People and Culture Committee The RPCC supports the Board by overseeing Origin’s remuneration policies and practices. It operates under a Charter (published on the Company’s website at originenergy.com.au). The RPCC met formally five times during the reporting period. Including its Chairman, the RPCC has four members, all of whom are independent NEDs (see Section 1 for details). The RPCC’s Charter requires a minimum of three NEDs. In addition, there is a standing invitation to all Board members to attend the RPCC’s meetings. Management may attend RPCC meetings by invitation, but a member of management will not be present when their own remuneration is under discussion. The following diagram sets out the role of the RPCC and its operational relationships with the Board, management, stakeholders and external advisors. 5.2 Remuneration advisors The RPCC engages external advisors from time to time to conduct benchmarking, advise on regulatory and market developments, and review proposals and reports. Protocols have been established for engaging and dealing with external advisors, including those defined as remuneration consultants for the purposes of the Act. These protocols are to ensure independence and avoid conflicts of interest. The protocols require that remuneration advisors are directly engaged by the RPCC and act on instruction from its Chairman. Reports must be delivered directly to the RPCC Chairman. The advisor is prohibited from communicating with Company management, except as authorised by the Chairman, and even then, this is limited to the provision or validation of factual and policy data. The advisor must furnish a statement confirming the absence of any undue influence from management. The RPCC generally seeks information rather than specific remuneration recommendations within the definition of the Act, and this was the case during FY2023. Guerdon Associates was appointed for this period – no remuneration recommendations as defined under the Act were provided. In addition, the RPCC makes use of general market trend information from a variety of commercial and industry sources, and has access to in-house remuneration professionals who provide it with guidance and analysis on request. The recommendations that the RPCC makes to the Board are based on its own independent assessment of the advice and information received from these multiple sources, using its experience and having careful regard to the principles and objectives of the remuneration framework, Company's performance, shareholder and community expectations, and good governance. 74 Annual Report 2023 5.3 Remuneration governance and oversight The Board’s oversight of executive performance and remuneration outcomes is rigorous and multi-phased. Its processes in overseeing performance and remuneration can be divided into the stages set out below, which are designed to ensure that outcomes are fair to executives and stakeholders, consistent in approach, and governed by documented principles. 5.3.1 Through the performance period Throughout the STI performance year and LTI vesting periods, the Board monitors and reviews management performance against financial and non-financial targets, including factors affecting the original assumptions underlying the setting of targets at the beginning of the relevant performance periods. Potential adjustments that may be required are considered under a set of protocols that cover materiality, symmetry of treatment for favourable and unfavourable events, the degree to which events are foreseeable and controllable by management, and the impact of Board decisions (for example, mergers and acquisitions). Any adjustments are subject to Board approval at the end of the performance period. The outcome from this stage comprises preliminary STI outcomes and preliminary LTI vesting outcomes. 5.3.2 At the end of the financial year At the end of each financial year, the full Board conducts a formal Executive Performance Review of the CEO and each member of the ELT, including the preliminary remuneration outcomes. The review is a formal and holistic process that considers: • risk, audit, compliance and reputation matters (including whistle-blowing, discrimination, bullying or harassment complaints, and safety and employee relations matters); • enterprise and business strategy contribution; and • leadership habits and behaviours. The process includes taking feedback from the: • Chair of the Health, Safety and Environment Committee; • Chair of the Audit Committee; • Internal Auditor; • General Counsel and EGM Company Secretariat, Risk and Governance; and • Executive General Manager, People and Culture.5 As a performance review process, the output includes performance feedback and identifies specifically whether there are any matters that warrant the exercise of downward discretion to modify individual executives’ preliminary remuneration outcomes. In exceptional circumstances, the Board may exercise upward discretion, within the capped opportunity level. During this stage, the Board will also consider whether any exercises of discretion are appropriate on a collective basis, and in the overall context of ensuring that the outcomes represent a reasonable and fair reflection of the Company’s performance from the perspective of all stakeholders. The output from this stage comprises final STI outcomes and final LTI vesting decisions. 5.3.3 Beyond the performance period Issues may emerge after final results have been notified where the Board deems that those results are no longer appropriate, or that the results would give rise to receiving an inappropriate benefit. Where such issues emerge before payment has been made or before rights have vested or shares have been released from trading locks, the Board may reduce or cancel the award or the vesting level, and/or extend the period of a trading lock under the Company’s malus provisions. The deferral period for equity (two years for STI and five years for all tranches of LTI) means that the exercise of malus is available for significant periods of time. Where benefits have been paid, vested or released, the Company’s clawback provisions give the Board further powers to recover cash proceeds from the sale of shares and to recover cash awards. These powers may be limited by statute or regulation. Of course, fraud, dishonesty, gross misconduct, negligence, breach of duties and other serious matters would have consequences additional to the remuneration impacts described above. Downward discretions have been exercised by the Board from time to time, both to STI outcomes and to LTI allocations or vesting outcomes, to provide better alignment of variable pay outcomes with the broader context and overall circumstances of the Company. There have been no circumstances to date in which the Board has sought to apply the clawback provisions. 5.4 Change of control and capital reorganisation If a change of control event occurs, the Board may determine that all or a specified number of unvested or restricted deferred incentives will vest or cease to be subject to restrictions. On a capital reorganisation, the Board may determine the manner of adjustment of the number of unvested Share Rights and Options held by participants to minimise or eliminate any material advantage or disadvantage to the participant. If new awards are granted, they will, unless the Board determines otherwise, be subject to the same terms and conditions as the original awards. 5 For the Executive General Manager, People and Culture, the feedback is from the CEO and/or the Chair of the RPCC. Remuneration Report 75 6 Non-executive Director fees 6.1 Remuneration policy and structure for Non-executive Directors NED remuneration comprises fixed fees with no incentive-based payments. This ensures that NEDs can independently and objectively assess both Executive and Company performance. Board and committee fees take into account market rates for similar positions at relevant Australian organisations (of comparable size and complexity) and fairly reflect the time commitments and responsibilities involved. The aggregate cap for overall NED remuneration remains at $3.2 million pa, as approved by shareholders in 2017. The Origin Chairman receives a single fee that includes committee activities, while other NEDs receive a NED Base Fee and separate fees for their role on specific committees (other than the Nomination Committee, which is considered within the NED Base Fee). All fees include superannuation contributions. The table below summarises the structure and level of NED fees. No change to the fee structure or quantum is proposed for FY2024. Office Board Audit Committee RPCC, Safety and Sustainability Committee, and Risk Committee Nomination Committee 1 The Chairman fee is inclusive of committee fees. Chairman 6771 57 47 nil FY2022 and FY2023 ($’000) Member 196 29 23.5 nil 6.2 Minimum Shareholding Requirement for Non-executive Directors To align the interests of the Board with those of shareholders, NEDs are required to build and maintain a substantive shareholding in the Company (the MSR). NEDs may purchase shares directly or through the NEDSP that was last approved by shareholders in 2022. The NEDSP is a fee sacrifice plan that allows NEDs to acquire share rights (rights to acquire fully paid ordinary shares in the Company) subject to the terms of the grant. The NEDSP is intended to facilitate the acquisition of shares for new Directors to meet their MSR obligation while recognising that opportunities for direct purchases by Directors may be limited. NEDs are expected to reach their MSR within three years of their appointment. During FY2023, one NED received a share allocation under the NEDSP in respect of the fees sacrificed during FY2022. The NED MSR is determined from time to time as a number of shares referenced to a nominal multiple of fees. The determination takes into account changes in fees and share prices over time. The nominal reference multiple is 100 per cent of the annual base NED fee for all NEDs except for the Chairman of the Board, where it is 200 per cent of the annual base NED fee. The current share determinations of 28,000 shares for NEDs and 56,000 shares for the Chairman are to be increased to 36,000 and 72,000, respectively, from August 2024. Share rights held by NEDs under the NEDSP will count towards the satisfaction of NED MSR obligations because they are funded through sacrifice of fees by the participating Director. The shares allocated on vesting of the share rights are bought on market on behalf of the Director and are not subject to forfeiture. Table 7-4 (b) shows that all NEDs meet the current MSR obligation. 76 Annual Report 2023 7 Statutory tables and disclosures Table 7-1 Executive service agreements The main terms of service agreements for Executive KMP as at 30 June 2023 are set out in the table below.

STI cash is paid after the end of the financial year to which it relates but is allocated to the earning year. The balance of the STI award is Deferred STI. 3 Movement in leave provision over the reporting period. Negative movement indicates that leave taken during the year exceeded leave accrued during the current year. 4 For FY2023 Deferred STI is delivered in the form of deferred cash arrangements. 5 Share-based incentives include Restricted Shares, PSR and RSRs granted as Deferred STI or LTI respectively. Share-based remuneration is that portion of the accounting value of equity granted or to be granted for the current and prior periods attributable to the reporting period. Where vesting of the equity is conditional on a non-market hurdle (for example, ROCE, or the underpinning metrics in the LTI RSR tranche) in following reporting periods, the accumulated expense is adjusted for the number of instruments then expected to be released or vested. In good leaver circumstances, a bring-forward of future-period accounting expense may occur where a cessation of employment occurs before the normal vesting date. See Note G3 for details on share-based remuneration accounting. 6 For FY2023, Cash STI also includes the value of the deferred remuneration retention arrangement ($450,000 conditionally payable after three years) attributable to the period. For FY2022, the pro-rata period for KMP office was from 1 November 2021 to 30 June 2022.

These were provided at no cost to the recipients. 3 All rights currently listed in this table are automatically exercised upon vesting. 4 Forfeited Options and PSRs were granted on 30 August 2017, 18 October 2017, 30 August 2019 and 18 October 2019. 5 Other than rights and shares disclosed elsewhere in this Remuneration Report, no other equity instruments, including shares in the Company, were granted to KMP during the period. 6 After vesting and after payment of any exercise price. The value of rights exercised is calculated as the closing market price of the Company’s shares on the ASX on the date of exercise, after deducting any exercise price. The exercise price for all of the rights referenced in this table is nil. 7 Shares include purchases and transfers in, and shares received upon the vesting and exercise of share rights (F Calabria: 111,375; J Briskin: 31,465; G Jarvis: 33,528; A Thornton: 11,253; L Tremaine: 41,778). It includes allotments of fully paid ordinary shares purchased by the Executive under the MSP (number of shares acquired: G Jarvis 734; J Briskin 734; A Thornton: 734; L Tremaine: 734). The value of shares shown relates to the value of restricted shares granted (as set out in Table 7-3). No value is attributed to the balance of shares acquired, as they represent shares arising from the exercise of share rights (the value of which is shown in the relevant share rights line of this table) or shares purchased by the Executive under the MSP. 80 Annual Report 2023 Table 7-4 (b) Details of, and movements in, ordinary shares of the Company – NEDs NEDs — current5 I Atlas M Brenner G Lalicker M McCormack S Perkins S Sargent N Scheinkestel J Withers6 NEDs — former B Morgan7 Type Shares Shares Shares Shares Shares Shares Shares Shares Shares Held at start1 Acquired2 Disposed3 Held at end1,4 50,000 28,367 100,000 100,000 80,000 41,429 33,365 26,000 0 0 0 0 0 0 0 3,980 47,143 0 0 0 0 0 0 0 0 0 0 50,000 28,367 100,000 100,000 80,000 41,429 33,365 29,980 47,143 1 The number of instruments held at the start/end of the reporting period. 2 Purchases and transfers in. 3 Sales and transfers out. 4 Other than shares disclosed elsewhere in this Remuneration Report, no other equity instruments, including shares in the Company, were granted to KMP during the period. 5 NEDs are not issued shares under any incentive or equity plans.

On 2 September 2022, J Withers was granted 3,980 NEDSP share rights pursuant to a salary sacrifice arrangement under the NEDSP. Each NEDSP share right had a value of $6.28, being the VWAP of Origin shares traded on the ASX over the five trading days period ending the day before the grant date (total value of $24,994). On 23 February 2023, all the NEDSP share rights vested and were automatically exercised into 3,980 fully paid ordinary shares, subject to a disposal restriction in accordance with the terms of the NEDSP. The value of the NEDSP share rights exercised was $31,840 and is calculated as the closing market price of the Company’s shares on the ASX on the date of exercise ($8.00). 7 B Morgan retired on 19 October 2022. As such, the ‘held at end’ balance is at this date.

Financial Statements 89 Overview Origin Energy Limited (the Company) is a for-profit company domiciled in Australia. The address of the Company’s registered office is Level 32, Tower 1, 100 Barangaroo Avenue, Barangaroo NSW 2000. The nature of the operations and principal activities of the Company and its controlled entities (the Group or Origin) are described in the segment information in note A1. On 17 August 2023, the Directors resolved to authorise the issue of these consolidated general purpose financial statements for the year ended 30 June 2023. Basis of preparation The financial statements have been prepared: • in accordance with the requirements of the Corporations Act 2001 (Cth), Australian Accounting Standards and other authoritative pronouncements of the Australian Accounting Standards Board (AASB), and International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board; • on a historical cost basis, except for derivatives and other financial assets and liabilities that are measured at fair value; and On 27 June 2023, the AASB issued amendments to AASB 112 Income Taxes. The amendments to AASB 112 give companies temporary relief from accounting for deferred taxes arising from the Organisation for Economic Co- operation and Development’s international tax reform (Pillar Two income taxes) and also introduce qualitative and quantitative disclosures to assist the users of financial statements to better understand a company’s exposure to income taxes arising from the reform, particularly before legislation implementing the rules is in effect. The temporary relief from accounting for deferred taxes was applicable immediately and retrospectively upon issue of the amendments while the disclosure requirements are effective for the Group for reporting periods beginning 1 July 2023. The Group has applied the temporary relief from accounting for and disclosing information about deferred tax assets and liabilities related to Pillar Two income taxes. As at the reporting date, the Group continues to monitor the developments around the implementation and enactment of Pillar Two income taxes in the jurisdictions it operates in and the detailed impact assessment of the amendments to AASB 112 is ongoing. • on a going concern basis. Use of judgements and estimates The financial statements: • are presented in Australian dollars; • are rounded to the nearest million dollars, unless otherwise stated, in accordance with Australian Securities and Investments Commission (ASIC) Corporations (Rounding in Financial/ Directors' Reports) Instrument 2016/191; • do not early adopt any Accounting Standards and Interpretations that have been issued or amended but are not yet effective; and • present reclassified comparative information where required for consistency with the current period's presentation. New standards and interpretations not yet adopted A number of new standards, amendments to standards and interpretations are effective for annual periods beginning after 1 July 2023, which have not been applied in preparing the Group’s financial statements. None of these are expected to have a significant effect on the Group with the exception of AASB 2023-2 Amendments to Australian Accounting Standards – International Tax Reform – Pillar Two Model Rules. Preparing the financial statements in conformity with Australian Accounting Standards requires management to make judgements and apply estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses. The estimates and associated assumptions, which are based on historical experience and various other factors believed to be reasonable under the circumstances, form the basis of judgements about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. Throughout the notes to the financial statements, further information is provided about key management judgements and estimates that we consider material to the financial statements. The Group's operating environment In the prior year, the Group's operating environment experienced very challenging energy market conditions, with high prices and periods of supply constraints. This was most evident with the Ukraine war and the move by many countries away from importing energy from Russia. This drove higher global energy prices and caused countries to place greater national importance on energy security. These factors have had wider impacts on consumers, businesses and the overall economy. The Group’s operating environment has become less volatile with a lower commodity price environment in the current year. The economic impacts of the changes in the Group's operating environment due to market conditions have implications for various line items in the financial statements. Binding Scheme Implementation Deed On 27 March 2023 the Company entered into a binding Scheme Implementation Deed (the Scheme) with the Consortium comprising affiliates of Brookfield Renewable Partners L.P. (Brookfield Renewable), together with its institutional partners and certain other global institutional investors, and MidOcean Energy, an entity managed by EIG Partners, for the acquisition of all the issued shares in the Company (the Scheme Transaction). Subject to the conditions of the Scheme, Brookfield Renewable and its institutional partners and investors will own the Energy Markets business and Corporate functions and MidOcean Energy will acquire the Integrated Gas business which includes Origin’s investment in APLNG. The Company and the Consortium are targeting implementation of the Scheme by early in the 2024 calendar year. The actual timing for implementation of the Scheme will depend on the timing for satisfaction of the required regulatory and shareholder approvals. The Consortium lodged an application with the Australian Competition and Consumer Commission on 5 June 2023, in accordance with the terms of the Scheme. Climate change Origin’s ambition is to lead the energy transition through cleaner energy and customer solutions. With a long-term ambition to achieve net-zero emissions by 2050, the Group is committed to progressively decarbonising its business and providing the solutions to help customers transition to a low-carbon future. The Group has identified certain key physical and transition risks relating to climate change. These include potential changes in market supply and demand for energy, government policy and regulation in relation to climate change, extreme weather events and other 90 Annual Report 2023 Overview (continued) technological advancements that might occur as the transition to a low-carbon economy unfolds. The Group continues to monitor climate- related legislation and policies that impact the financial statements and will incorporate any required changes as they arise. We recognise that there is significant uncertainty around the pace of decarbonisation and differing pathways to net zero across the global economy. Future changes to the Group’s ambition or realisation of global decarbonisation ambitions quicker or more slowly than currently anticipated may impact some of the Group’s significant judgements and key estimates. In preparing the financial statements, the key judgements and estimates consider a range of economic conditions that are forecast to exist over the remaining useful lives of the Group's assets, including expectations about future operations, the current outlook for commodity prices, discount rates, capital expenditure requirements and market supply and demand profiles. Climate change-related risks will impact those areas of the financial statements that are subject to estimation uncertainties and can also introduce more volatility in assets and liabilities carried at fair value. Climate change-related risks impact the significant judgements and estimates in the following notes to the financial statements: • B2 - Investment in APLNG • C3 - Property, plant and equipment • C4 - Intangible assets • C5 - Provisions - restoration • C7 - Impairment of non-current assets • D5 - Fair value of financial assets and liabilities In February 2022, the Group announced plans to accelerate its exit from coal-fired power generation submitting notice to the Australian Energy Market Operator (AEMO) of its intention to bring forward the closure of the Eraring Power Station (Eraring) to as early as August 2025. Prevailing market conditions will continue to be assessed which will help inform the final timing for closure of all four units at Eraring. As at 30 June 2023 and consistent with the prior year, a closure date of August 2025, the end of the required three and a half year notice period to AEMO, remains the Group’s best estimate of useful life and has been used in the accounting assessments presented within these financial statements; namely, the recoverable amount estimates in the Energy Markets Generation CGU (note C7), useful life assumptions of Eraring in calculating depreciation expense (note C3) and timing of associated restoration activities recognised in the provision balance (note C5). The Group recognises the increase in legislative momentum to address climate change-related risks and opportunities, including the Australian Government’s emissions reduction target legislated in September 2022 and the amendments to the Safeguard Mechanism which have come into force mid-2023. The Group has considered the impact of these legislative requirements in line with accounting standard requirements, with no impairment required as at 30 June 2023 due to the introduction of the Safeguard Mechanism. Paris Agreement and climate scenarios The Group unequivocally supports the goal of the Paris Agreement and believes the world must pursue efforts to limit global average temperature rise to 1.5°C above preindustrial levels. The Group recognises that there are a range of possible energy transition scenarios that align to this goal. In line with our commitment at the 2022 Annual General Meeting, we have disclosed the estimates and judgements used in presenting a quantified climate analysis. The Group’s climate scenarios disclosed are based on the following: • International Energy Agency (IEA) Net Zero Emissions by 2050 scenario (NZE) as presented in their World Energy Outlook 2022 (WEO 2022) (November 2022) publication. • Wood Mackenzie1 (Woodmac) 2022 Accelerated energy transition 1.5- degree scenario (2022 AET-1.5°C). • IEA Announced Pledges scenario (APS) (WEO 2022). Both the IEA NZE and Woodmac 2022 AET-1.5°C scenarios are intended to be consistent with the goal of the Paris Agreement to limit average temperature rise to 1.5°C. However, the Group recognises that globally we may not be on a trajectory consistent with the IEA NZE 1.5°C pathway and therefore have also included the IEA APS scenario. The APS scenario considers the impact of all pledges announced as of September 2022 by governments to meet net zero goals, and is estimated to limit the global average temperature rise to 1.7°C. Climate scenarios – assumptions and methodology Although all potential financial reporting consequences under any climate scenario are impracticable to fully assess, the Group has used the following assumptions in order to assess the impact of a climate scenario to the financial statements. IEA APS and IEA NZE Scenarios The IEA APS and IEA NZE scenarios released in the WEO 2022 present commodity pricing starting from historical market balances in 2021. To reflect the economic challenges the business will face in the energy transition, the Group has used the oil, LNG and carbon prices from the Group’s FY2024 base case assumptions used for impairment assessment and assumed a straight-line interpolation to the earliest subsequent period provided by the IEA APS and IEA NZE scenarios. A straight- line interpolation is then assumed between each of the IEA price points provided up to 2050, where prices are held flat for any subsequent periods. As all prices presented in the IEA WEO 2022 are 2021 real unit pricing, the Group has adjusted these prices by an assumed 2.5% per annum inflation factor to reflect 2023 real unit pricing. Woodmac 2022 AET-1.5°C Scenario The Woodmac 2022 AET-1.5°C scenario presents commodity pricing for each year through to 2050 based on 2022 real unit pricing. For use in the Group’s scenario analysis, these prices have been uplifted by an assumed 2.5% inflation factor to reflect 2023 real unit pricing. No other adjustments have been made to the Woodmac 2022 AET-1.5°C commodity pricing. Limitations of scenario analysis Scenarios do not constitute definitive outcomes or probabilities, and scenario analysis relies on assumptions that may or may not be, or prove to be, correct and may or may not eventuate. Scenarios may also be impacted by additional factors to the assumptions disclosed. While each of the climate scenarios presented are founded on differing assumptions, central themes across each of these scenarios include the need for swift policy action, technological uplift, and investment in the energy transition on an unprecedented global scale. It is difficult to predict, which if any, of these assumptions and scenarios may eventuate. Furthermore, the IEA has recognised that the transition is extremely challenging and that globally we are not on the IEA NZE pathway. 1 The data and information were obtained from the Accelerated Energy Transition 1.5-degree scenario 2022, a product of Wood Mackenzie.

Therefore in its design, the Group’s base case assumptions used for impairment differ to the key assumptions used in the scenarios presented in the climate analysis. Notwithstanding, the Group will continue to take action across the business both now and beyond 2030 with the ambition of reaching net zero Scope 1, 2 and 3 emissions across our value chain by 2050. Commodity price assumptions 2 The commodity prices used in the climate scenarios are as follows (presented in 2023 real unit pricing): Brent Oil USD/bbl 100 75 50 25 0 2025 2030 2040 2050 IEA APS scenario IEA NZE scenario Woodmac 2022 AET-1.5°C scenario USD/mmbtu LNG 40 30 20 10 0 2025 2030 2040 2050 IEA APS scenario IEA NZE scenario Woodmac 2022 AET-1.5°C scenario Carbon USD/t 320 240 160 80 0 2025 2030 2040 2050 IEA APS scenario IEA NZE scenario Woodmac 2022 AET-1.5°C scenario The AEMO “Strong Electrification” scenario per their 2022 Electricity Statement of Opportunities (August 2022) (ESOO) publication provides supply and demand forecasts for both the gas and electricity sector that are aligned with the IEA NZE scenario. The AEMO “Strong Electrification” forecasts are used in conjunction with the IEA NZE commodity assumptions in the graphs above to develop relevant energy market pricing. In presenting the quantified climate analyses, we have assumed in all climate scenarios that carbon pricing has been applied to Scope 1 emissions above the estimated Safeguard Mechanism facility baseline and all Scope 2 emissions. For the IEA NZE and Woodmac 2022 AET-1.5°C scenarios, the Group has also assumed a net zero grid by 2035 and therefore has no Scope 2 emissions beyond 2035. This is intended to be consistent with the economic principles that support the AEMO “Strong Electrification” scenario and has therefore been applied when modelling these selected 1.5°C scenarios. The quantified impact of applying the climate scenarios to the financial statements are as follows: Energy Markets For Energy Markets, the application of the IEA NZE and AEMO “Strong Electrification” climate scenarios result in a net favourable position compared to the outlook from the base case assumptions used for impairment, benefiting existing assets such as the peaking generation fleet and Power Purchase Agreements (PPAs). Increased electrification of the National Electricity Market (NEM) and other growth areas such as electric vehicle penetration and an increase in connected services as customers decarbonise their homes will provide further opportunities for the retail business. The climate scenario valuation assumes closure of Eraring in August 2025, which therefore limits the exposure of the carrying value of assets in the Energy Markets segment to long-term commodity price movements. There is no expected impact to the useful lives of the remaining assets or restoration and rehabilitation provisions under the IEA NZE scenario. Accounting standards require any decision as to impairments or reversals to be based on management’s best estimate of economic conditions over the assets remaining useful life. Given the IEA NZE scenario is not viewed as the most likely economic outcome, it is not an appropriate basis on which to determine or quantify impairment or potential impairment reversals. Historical impairments within the Energy Markets segment have largely pertained to goodwill, which, in accordance with accounting standards, cannot be reversed. Investment in APLNG For the Group’s investment in APLNG, the outcomes of the climate scenarios are as follows: Carrying value as at 30 June 2023 5,469 $m Impairment arising in selected scenarios: IEA APS Woodmac 2022 AET-1.5°C IEA NZE nil nil 2,440 The climate analysis disclosed is presented based on the adjustment of pricing assumptions alone, the exception being the IEA NZE and Woodmac 2022 AET-1.5°C scenarios where no scope 2 emissions are assumed from 2035 onwards. This is intended to be consistent with the assumption of the net zero grid by 2035 applied in the AEMO “Strong Electrification” scenario. No other adjustments or mitigating actions have been applied and all modelling is conducted in accordance with AASB and IFRS measurement requirements. In practice these valuations do not reflect any actions management may take in order to reduce negative outcomes and further grow the business. If presented with such a sustained low-price environment, APLNG would adjust future long-term expenditure, production and operations in order to reduce the overall unfavourable impact, therefore the illustrative impairments presented under the climate scenarios above are likely higher than what would transpire. 2 The data presented in the graphs as the Woodmac 2022 AET-1.5 °C scenario was obtained from the Accelerated Energy Transition 1.5-degree scenario 2022, a product of Wood Mackenzie.

These items are determined after consideration of the nature of the item, the significance of the amount and the consistency in treatment from period to period. The nature of items excluded from underlying profit and underlying EBITDA are shown below. • Changes in the fair value of financial instruments not in accounting hedge relationships, to remove the significant volatility caused by timing mismatches in valuing financial instruments and the related underlying transactions. The valuation changes are subsequently recognised in underlying earnings when the underlying transactions are settled; • Realised and unrealised foreign exchange gains/losses on debt held to hedge USD-denominated investment in APLNG; • Significant redundancies and other costs in relation to business restructuring, transformation or integration activities; • Gains/losses on the sale or acquisition of an asset/entity; • Transaction costs incurred in relation to the sale or acquisition of an entity; • Impairments of assets; • Significant onerous contracts; • Deferred tax liability recognition/ utilisation relating to the APLNG investment; • Large-scale Generation Certificates (LGCs) net shortfall charge; and • Other significant non-recurring items. A Results for the year This section highlights the performance of the Group for the year, including results by operating segment, income and expenses, results of equity accounted investees, earnings per share and dividends. A1 Segments The Group's operating segments are presented on a basis that is consistent with the information provided internally to the Managing Director, who is the chief operating decision maker. This reflects the way the Group's businesses are managed, rather than the legal structure of the Group. The reporting segments are organised according to the nature of the activities undertaken and are detailed below. • Energy Markets: Energy retailing and wholesaling, power generation and LPG operations predominantly in Australia. • Share of Octopus Energy: Origin's • investment in Octopus Energy Holdings (Octopus Energy). This investment was previously included in the Energy Markets segment. Integrated Gas: Origin's investment in APLNG, exploration interest in the Cooper-Eromanga Basin and costs associated with growth initiatives such as hydrogen. It also includes overhead costs (net of recoveries from APLNG) and costs incurred in managing Origin’s exposure to LNG pricing risk and impacts of its LNG trading positions. For greater transparency, the investment in APLNG is presented separately from the residual component of the segment. • Corporate: Various business development and support activities that are not allocated to operating segments, including corporate treasury and tax items. Underlying profit and underlying EBITDA are non-statutory (non-IFRS) measures. The objective of measuring and reporting underlying profit and underlying EBITDA is to provide a more meaningful and consistent representation of financial performance by removing items that distort performance or are non-recurring in nature.

Key judgements and estimates The Group recognises revenue from electricity and gas sales once the energy has been consumed by the customer. When determining revenue for the financial period, management estimates the volume of energy supplied since a customer's last bill. The estimation of unbilled consumption requires judgement and is based on various assumptions including: • volume and timing of energy consumed by customers; • allocation of estimated electricity and gas volumes to various pricing plans; • discounts linked to customer payment patterns; and • loss factors. Management also uses unbilled consumption volumes to accrue network expenses incurred by the Group for unread customer electricity and gas meters. The calculation of unbilled revenue requires significant judgement in estimating the level of energy consumption by customers during the unbilled period to 30 June 2023. The Group uses a backcasting model and volume-matching process to provide a reliable estimate of unbilled revenue as at 30 June 2023. Retail contracts Retail electricity is generally marketed through standard service offers that provide customers with discounts on published tariff rates. Contract duration can vary with some contracts providing a discount on published rates for a limited term, while other contracts have no fixed duration. Contracts generally require no minimum consumption, and can be terminated by the customer at any time without significant penalty. The supply of energy is considered a single performance obligation for which revenue is recognised upon delivery to customers at the offered rate. Where customers are eligible to receive additional behavioural discounts, Origin considers this to be variable consideration. Business and wholesale contracts Contracts with business and wholesale customers are generally medium to long-term, higher-volume arrangements with fixed or index-linked energy rates that have been commercially negotiated. The nature and accounting treatment of this revenue stream is largely consistent with retail sales. Some business and wholesale sales arrangements also include the transfer of renewable energy certificates (RECs), which represent an additional performance obligation. Revenue is recognised for these contracts when Origin has the 'right to invoice' the customer for consideration that corresponds directly with the value of units of energy delivered to the customer. Pool revenue relates to sales by Origin generation assets into the NEM, as well as revenue associated with gross settled PPAs. Origin has assessed it is acting as the principal in relation to transactions with the NEM and therefore recognises pool sales on a gross basis. Revenue from these sales is recognised at the spot price achieved when control of the electricity passes to the grid. Financial Statements 97 A2 Revenue (continued) Solar and Energy services Solar and Energy Services revenue primarily relates to sales of solar, batteries and Community Energy Services. Solar and batteries revenue includes the sale, installation, repairs and maintenance services of solar photovoltaic systems, and battery solutions, to residential and business customers. Revenue is recognised at the point in time that the system is installed, or the service provided is complete. Community Energy Services supplies electricity and gas within embedded network sites. Similar to retail contracts, the supply of energy is considered a single performance obligation for which revenue is recognised upon delivery to the customers at the offered rate. LPG and Integrated Gas Revenue from the sale of LPG (Energy Markets segment) and LNG (Integrated Gas segment) is recognised at the point in time that the customer takes physical possession of the commodity. Revenue is recognised at an amount that reflects the consideration expected to be received.

At the same time, when APLNG paid interest to the Group on MRCPS, the amount was capitalised by APLNG. Therefore, these capitalised interest amounts form part of the cost of APLNG's assets, and these assets have been depreciated since commencement of operations. The proportion attributable to the Group’s own interest (37.5 per cent prior to 8 December 2021 and 27.5 per cent thereafter) is eliminated through the equity accounted investment balance. 3 Includes an increase of $245 million due to foreign exchange that has been recognised in the foreign currency translation reserve. Also included is a reduction of A$1,783 million (US$1,198 million) relating to unfranked dividends received from APLNG. Reporting date balances are converted from USD to AUD using an end-of-period exchange rate of 0.6629 (2022: 0.6891). Key judgements and estimates The carrying amount of the Group's equity accounted investment in APLNG is reviewed at each reporting date to determine whether there is any indication of impairment or reversal of impairment. Where an indicator of impairment exists, a formal estimate of the recoverable amount is made. The Group’s assessment of the recoverable amount uses a discounted cash flow methodology and considers a range of macroeconomic and project assumptions, including oil and LNG price, AUD/USD exchange rates, discount rates and costs over the asset's life. No impairment loss or reversal of impairment was recognised during the year. Climate change is a material risk that can affect the Group’s operations through current and future climate-related legislation and policies and climate related scenarios. Future climate related conditions, legislation and policies may have an impact on future commodity prices, foreign exchange rates, discount rates, inflation, global market supply and demand conditions and whether reserve quantities are capable of economic extraction.

The Group incurs costs in providing these services and charges APLNG for them in accordance with the terms of the contracts governing those services. Commodity transactions Separately, the Group has entered agreements to purchase gas from APLNG (2023: $636 million; 2022: $401 million) and sell gas to APLNG (2023: $40 million; 2022: $17 million). At 30 June 2023, the Group's outstanding payable balance for purchases from APLNG was $59 million (2022: $25 million) and outstanding receivable balance for sales to APLNG was nil (2022: $7 million). Funding transactions The Group received unfranked dividends of $1,783 million (2022: $433 million.) On 18 July 2023 the directors of APLNG determined unfranked dividends to be paid to shareholders. The Group received unfranked dividends of US$65 million (A$98 million) on 26 July 2023. On 15 August 2023 the directors of APLNG determined further unfranked dividends to be paid to shareholders. The Group expects to receive US$115 million on 29 August 2023. In the prior year, Origin repaid $51 million of the DSRA loan from APLNG under the APLNG project finance debt service reserve account requirements. In the prior year the Group received A$1,162 million of MRCPS buy-backs and reflected a reduction in the MRCPS non-current financial asset. Related MRCPS dividends of A$50 million were recognised as interest income. The APLNG MRCPS were fully bought back as at 30 June 2022. Octopus Energy Additional equity transactions On 9 August 2022 an additional investment of £94 million (A$163 million) was paid by the Group to Octopus Energy to restore its 20 per cent equity interest. In January 2023 the Group invested a further £5.6 million (A$10 million), following further investments by other shareholders, to maintain its 20 per cent equity interest. Financial guarantee The Group provided a financial guarantee to Octopus Energy’s financiers and during the year, $6 million (2022: $9 million) was recognised within other income in respect of the financial guarantee income. The financial guarantee expired in March 2023. Kraken technology platform milestone payment The £10 million (A$20 million) final milestone payment was paid in May 2023. Financial Statements 105 C Operating assets and liabilities This section provides information on the assets used to generate the Group's trading performance and the liabilities incurred as a result. C1 Trade and other receivables The following balances are amounts due from the Group's customers and other parties. Current Trade receivables net of allowance for impairment Unbilled revenue net of allowance for impairment Other receivables Total current Non-current Trade receivables Total non-current 2023 $m 867 1,457 224 2,548 60 60 2022 $m 724 2,107 540 3,371 45 45 Trade and other receivables are initially recorded at the amount billed to customers or other counterparties. Unbilled receivables represent estimated gas and electricity supplied to customers since their previous bill was issued. The carrying value of all receivables, including unbilled revenue, reflects the amount anticipated to be collected. Key judgements and estimates Recoverability of trade receivables: Judgement is required in determining the level of provisioning for customer debts. Impairment allowances take into account the age of the debt, historic collection trends and expectations about future economic conditions. Unbilled revenue: Unbilled gas and electricity revenue is not collectable until customers' meters are read and invoices issued. Refer to note A2 for judgement applied in determining the amount of unbilled energy revenue to recognise. Credit risk and collectability The Group minimises the concentration of credit risk by undertaking transactions with a large number of customers from across a broad range of industries. Credit approval processes are in place for large customers and all customers are required to pay in accordance with agreed payment terms. Depending on the customer segment, settlement terms are generally 14 to 30 days from the date of the invoice. For some debtors, the Group may also obtain security in the form of deposits, guarantees, deeds of undertaking or letters of credit, which can be called upon if the counterparty defaults. Debtor collectability is assessed on an ongoing basis and any resulting impairment losses are recognised in the income statement. The Group applies the simplified approach to providing for trade receivable and unbilled revenue impairment, which requires the expected lifetime credit losses to be recognised when the receivable is initially recognised. To measure expected lifetime credit losses, trade receivables and unbilled revenue balances have been grouped based on shared credit risk characteristics and ageing profiles. A debtor balance is written off when recovery is assessed to be no longer possible. 106 Annual Report 2023 C1 Trade and other receivables (continued) As at 30 June 2023, the allowance for impairment in respect of trade receivables and unbilled revenue is $238 million (2022: $186 million). The average age of trade receivables is 22 days (2022: 18 days). Other receivables are neither past due nor impaired and relate principally to generation and hedge contract receivables. The ageing of current trade receivables and unbilled revenue at the reporting date is detailed below. $m Unbilled revenue Not yet due Less than 30 days 31-60 days past due 61-90 days past due Greater than 91 days Total 2023 2022 Gross 1,473 629 114 50 36 260 2,562 Impairment allowance (16) (35) (4) (7) (7) (169) (238) Gross 2,120 539 86 49 30 193 3,017 The movement in the allowance for impairment in respect of trade receivables and unbilled revenue during the year is shown below.

Refer to note F4. The Group holds a number of exploration permits that are grouped into areas of interest according to geographical and geological attributes. Expenditure incurred in each area of interest is accounted for using the successful efforts method. Under this method, all general exploration and evaluation costs are expensed as incurred except the direct costs of acquiring the rights to explore, drilling exploratory wells and evaluating the results of drilling. These direct costs are capitalised as exploration and evaluation assets pending the determination of the success of the well. If a well does not result in a successful discovery, the previously capitalised costs are immediately expensed. The carrying amounts of exploration and evaluation assets are reviewed at each reporting date to determine whether any of the following indicators of impairment are present: • • • • the right to explore has expired, or will expire in the near future, and is not expected to be renewed; further exploration for and evaluation of resources in the specific area is not budgeted or planned for; the Group has decided to discontinue activities in the area; or there is sufficient data to indicate the carrying value is unlikely to be recovered in full from successful development or by sale. Where an indicator of impairment exists, the asset's recoverable amount is estimated. If it is concluded that the carrying value of an exploration and evaluation asset is unlikely to be recovered by future exploitation or sale, an impairment is recognised in the income statement for the difference. Key judgement Recoverability of exploration and evaluation assets Assessment of the recoverability of capitalised exploration and evaluation expenditure requires certain estimates and assumptions to be made as to future events and circumstances, particularly in relation to whether economic quantities of reserves have been discovered. Such estimates and assumptions may change as new information becomes available. Additionally, future climate-related conditions, legislation and policies may impact whether reserve quantities are capable of economic extraction. The recoverability of these assets continues to be monitored by the Group. Such estimates and assumptions may change as new information becomes available. Upon approval of the commercial development of a project, the exploration and evaluation asset is classified as a development asset. Once production commences, development assets are transferred to PP&E. 108 Annual Report 2023 C3 Property, plant and equipment Owned Right-of-use (ROU) Total Plant and equipment Land and buildings Capital work in progress Plant and equipment Land and buildings $m 2023 Cost Less: Accumulated depreciation and impairment losses Total Balance as at 1 July 2022 Additions Net restoration movement Disposals Modifications to lease terms Depreciation/amortisation Transfers within PP&E Transfers to assets held for sale 6,030 (3,852) 2,178 2,303 72 13 (26) - (316) 164 (32) 185 (78) 107 115 - - - - (2) - (6) 107 Balance as at 30 June 2023 2,178 2022 Cost Less: Accumulated depreciation and impairment losses Total Balance as at 1 July 2021 Additions Net restoration movement Disposals Modifications to lease terms Depreciation/amortisation Transfers within PP&E Transfers to intangibles Effect of movements in foreign exchange rates Balance as at 30 June 2022 5,952 194 (3,649) 2,303 2,458 41 (31) (9) - (216) 60 (3) 3 2,303 (79) 115 112 6 - - - (3) - - - 115 420 - 420 371 213 - - - - (164) - 420 371 - 371 317 114 - - - - (60) - - 371 287 400 7,322 (92) 195 169 35 - - 43 (46) - (6) 195 (131) 269 297 - - (5) 9 (32) - - 269 (4,153) 3,169 3,255 320 13 (31) 52 (396) - (44) 3,169 266 397 7,180 (97) 169 84 127 - - 12 (54) - - - (100) 297 320 1 - (78) 85 (31) - - - (3,925) 3,255 3,291 289 (31) (87) 97 (304) - (3) 3 169 297 3,255 Owned PP&E PP&E is recorded at cost less accumulated depreciation, amortisation and impairment charges. Cost includes the estimated future cost of required closure and rehabilitation. The carrying amounts of assets are reviewed to determine if there is any indication of impairment. If any such indication exists, the asset's recoverable amount is estimated and if required, an impairment is recognised in the income statement. Depreciation is calculated on a straight-line basis so as to write off the cost of each asset over its expected useful life. Leasehold improvements are amortised over the period of the relevant lease or estimated useful life, whichever is shorter. Land and capital work in progress are not depreciated. The estimated useful lives used in the calculation of depreciation are shown below. • Buildings, including leasehold improvements 10 to 50 years • Plant and equipment 3 to 30 years Financial Statements 109 C3 Property, plant and equipment (continued) Leased PP&E The Group's leased assets include commercial offices, power stations, LPG terminals and shipping vessels, motor vehicles and other items of equipment. ROU assets are recognised at the commencement of a lease. ROU assets are initially valued at the corresponding lease liability amount adjusted for any payments already made, lease incentives received, or initial direct costs incurred when entering into the lease. Where the Group is required to restore the ROU asset at the end of the lease, the cost of restoration is also included in the value of the ROU asset. ROU assets are depreciated on a straight-line basis over the shorter of the lease term or the useful life of the ROU asset. The carrying amounts of ROU assets are reviewed to determine if there is any indication of impairment. If any such indication exists, the asset's recoverable amount is estimated, and if required, an impairment is recognised in the income statement. Refer to note D2 for discussion of the recognition and measurement of associated lease liability balances. Key judgements and estimates Recoverability of carrying values: Estimates of recoverable amounts are based on an asset’s value-in-use or fair value less costs to sell, whichever is higher. The recoverable amount of these assets is sensitive to changes in key assumptions. Estimation of useful economic lives: A technical assessment of the operating life of an asset requires significant judgement. Useful lives are amended prospectively when a change in the operating life is determined. The estimated useful lives of our assets align with our climate change strategy commitments. Eraring Power Station useful life: The useful life of Eraring remains unchanged at August 2025 for the purpose of accounting assessments presented within these financial statements. Prevailing market conditions will continue to be assessed which will help inform the final timing of closure of all four units at Eraring. Refer to the Strategy and climate change risks section in the Overview. Restoration provisions: An asset's carrying value includes the estimated future cost of required closure and rehabilitation activities. Refer to note C5 for the judgement related to restoration provisions. Climate change risks: Future climate-related conditions, legislation and policies may have an impact on these estimates and continues to be monitored. Lease term: Where lease arrangements contain options to extend the term or terminate the contract, the Group assesses whether it is 'reasonably certain' that the option to extend or terminate will be exercised. Consideration is given to all facts and circumstances that create an economic incentive to extend or terminate the contract. Lease liabilities and ROU assets are measured using the reasonably certain contract term. 110 Annual Report 2023 C4 Intangible assets Goodwill net of impairment losses Software and other intangible assets Accumulated amortisation Total Reconciliations of the carrying amounts of each class of intangible asset are set out below. $m Balance as at 1 July 2022 Additions1 Transfers to assets held for sale Amortisation expense Balance as at 30 June 2023 Balance as at 1 July 2021 Additions2 Transfers from PP&E Impairment3 Amortisation expense Balance as at 30 June 2022 2023 $m 1,964 1,786 (1,257) 2,493 Goodwill Software and other intangibles 1,965 - (1) - 1,964 4,136 25 - (2,196) - 1,965 558 103 (1) (131) 529 522 183 3 - (150) 558 2022 $m 1,965 1,684 (1,126) 2,523 Total 2,523 103 (2) (131) 2,493 4,658 208 3 (2,196) (150) 2,523 1 Additions include amounts relating to the build of the Kraken technology platform and $6 million of other intangibles related to the acquisition of Yanco Solar Farm. 2 Includes $77 million of software and other intangibles related to the acquisition of WINconnect Pty Ltd and $25 million of goodwill. Additions also include $15 million related to the acquisition of Yarrabee Solar Farm and $12 million related to the acquisition of the Carisbrook Solar Farm. 3 Relates to the impairment of Energy Markets segment goodwill. Refer to note C7. Goodwill is stated at cost less any accumulated impairment losses and is not amortised. Software and other intangible assets are stated at cost less any accumulated impairment losses and accumulated amortisation. Amortisation is recognised as an expense on a straight-line basis over the estimated useful lives of the intangible assets. The average amortisation rate for software and other intangibles (excluding capital work in progress) was 9 per cent (2022: 11 per cent).

Also included within this balance are rehabilitation provisions for contamination at existing and legacy operating sites. 2 All material contracts in which the unavoidable costs of meeting the obligations exceed the economic benefits are deemed onerous and require a provision to be recognised upfront. This balance relates to an onerous contract provision of $62 million (US$41 million) (2022: $397 million (US$273 million)) for the LNG sales contract with ENN. 3 The closing balance of other provisions primarily relates to costs for compliance with safety standard requirements relating to the Eraring ash dam wall, costs associated with the new Myuna Bay Recreation Centre facility, costs associated with the Eraring Power Station closure and a make good provision relating to existing property leases. Restoration provisions are initially recognised at the best estimate of the costs to be incurred in settling the obligation. Where restoration activities are expected to occur more than 12 months from the reporting period, the provision is discounted using a risk-free rate that reflects current market assessments of the time value of money. The unwinding of the discount is recognised in each period as interest expense. At each reporting date, the restoration provision is remeasured in line with changes in discount rates, and changes to the timing or amount of costs to be incurred, based on current legal requirements and technology. Any changes in the estimated future costs associated with: • Restoration and dismantling are added to or deducted from the related asset; and • Environmental rehabilitation are expensed in the current period. Key estimate Restoration, rehabilitation and dismantling costs The Group estimates the cost of future site restoration activities at the time of installation or construction of an asset, or when an obligation arises. Restoration often does not occur for many years and thus significant judgement is required as to the extent of work, cost and timing of future activities. Future social, regulatory and climate-related conditions and policies may have an impact on these estimates and will continue to be monitored. The useful life of Eraring remains unchanged at August 2025 for the purpose of accounting assessments presented within these financial statements. Prevailing market conditions will continue to be assessed which will help inform the final timing of closure of all four units at Eraring.

The prior year financial guarantee related to the working capital facility entered into by Octopus Energy with its financiers, as referred to in note B4, for which the Group had provided a guarantee. C7 Impairment of non-current assets Cash-generating units Assets are grouped together into the smallest group of individual assets that generate largely independent cash inflows (cash-generating unit or (CGU)). The Energy Markets segment consists of the following materially distinct CGUs: • Retail CGU: incorporates Mass Market customers, Commercial & Industrial customers and the Wholesale & Trading businesses for electricity and natural gas commodities. The Wholesale & Trading business includes various electricity power purchase agreements and major wholesale gas supply contracts. • Generation CGU: incorporates cash flows from Origin's power stations. • LPG CGU: supplies and distributes LPG to residential and business locations across Australia and the Pacific. The carrying amounts of the CGUs are reviewed at each reporting date to determine whether there is any indication of impairment. Where an indicator of impairment exists, or where goodwill is present, a formal estimate of the recoverable amount is made. Only the Retail CGU contains a material goodwill balance and an impairment assessment of the recoverable amount was performed in the current and prior year. Financial Statements 113 C7 Impairment of non-current assets (continued) Recoverable amount The recoverable amount of the Retail CGU has been determined using value-in-use models that include an appropriate terminal value. The value-in-use calculations are sensitive to a number of key assumptions requiring management judgement, including future commodity prices, regulatory policies, and the outlook for the market supply-and-demand conditions. The key assumptions used by the Group in its impairment assessment are shown in the table below. Key assumptions Energy Markets Commodity prices Future commodity price assumptions impact the recoverability of carrying values and are reviewed at least twice annually. The Group's estimate of future commodity prices is made with reference to internally derived forecast data, current spot prices, external market analysts' forecasts and forward curves. Where volumes are contracted, future prices reflect the contracted price. Long-term growth rates Cash flows are projected for the term of electricity PPAs and major wholesale supply contracts in the Retail CGU. Other Retail CGU cash flows are projected for five years. The growth rate used to extrapolate Retail cash flows beyond the initial period projected averages 2.3 per cent, analogous to long term Consumer Price Index. Customer numbers This is based on a review of actual customer numbers and historical data regarding levels of customer churn. The historical analysis is considered against current and expected market trends and competition for customers. Gross margin and operating cost This is based on a review of actual gross margins and cost per customer, and consideration of current and expected market movements and impacts. Discount rate Discount rates used are the pre-tax equivalent of a post-tax discount rate of 7.5 per cent (2022: 7.2 per cent). Climate risk The Group continues to develop its assessment of the potential impacts of climate change and the transition to a low-carbon economy and this has been considered in the assumptions used as part of the recoverable amount assessment. No impairment loss was recognised during the year (2022: $2,196 million). The impairment loss in the prior year was allocated to goodwill in the Retail CGU and cannot be reversed in future periods. Refer to the Strategy and climate change risks section in the Overview for further analysis of the recoverable amount of non-current assets applying the Group’s climate scenario analysis. 114 Annual Report 2023 D Capital, funding and risk management This section focuses on the Group's capital structure and related financing costs. Information is also presented about how the Group manages capital, and the various financial risks to which the Group is exposed through its operating and financing activities. D1 Capital management The Group’s objective when managing capital is to make disciplined capital allocation decisions between investment in growth, distributions to shareholders and to maintain an optimal capital structure while maintaining access to capital. Management believes that a strong investment-grade credit rating (Baa2) and an appropriate level of net debt are required to meet these objectives. The Group's current credit rating is Baa2 (stable outlook) from Moody's. Key factors considered in determining the Group's capital structure and funding strategy at any point in time include expected operating cash flows, capital expenditure plans, the maturity profile of existing debt facilities, the dividend policy, and the ability to access funding from banks, capital markets and other sources. The Group monitors its capital requirements through a number of metrics including the gearing ratio (target range of approximately 20 to 30 per cent) and an adjusted net debt to adjusted underlying EBITDA ratio (target range of 2.0x to 3.0x). These targets are consistent with attaining a strong investment-grade rating. Underlying EBITDA is a non-statutory (non-IFRS) measure. The gearing ratio is calculated as adjusted net debt divided by adjusted net debt plus total equity. Net debt, which excludes cash held by Origin to fund APLNG-related operations, is adjusted to take into account the effect of FX hedging transactions on the Group’s foreign currency debt obligations. The adjusted net debt to adjusted underlying EBITDA ratio is calculated as adjusted net debt divided by adjusted underlying EBITDA (Origin's underlying EBITDA less Origin's share of APLNG underlying EBITDA and Origin’s share of Octopus Energy underlying EBITDA plus net cash flow from APLNG) over the relevant rolling 12-month period. The Group monitors its current and future funding requirements for at least the next five years and regularly assesses a range of funding alternatives to meet these requirements in advance of when the funds are required.

After that date, the liability is amortised to face value at maturity using an effective interest rate method. Lease liabilities are initially measured at the present value of future lease payments discounted at the Group's incremental borrowing rate. Where a lease includes termination and/or extension options, the impact of these options on the amount of future payments is included where exercise of such options is considered reasonably certain to occur. Interest expense is charged on outstanding lease liabilities that reduce over time as periodic payments are made. The lease liability is remeasured when certain events occur, including changes in the lease term or changes in future lease payments such as those resulting from inflation-linked indexation or market rate rent reviews. On remeasurement of lease liabilities, a corresponding adjustment is made to the ROU asset. The contractual maturity of lease liabilities is disclosed within the liquidity table in note D4.

The Group does not have authorised capital or par value in respect of its issued shares. Treasury shares Where the Group or other members of the Group purchase shares in the Company, the consideration paid is deducted from the total shareholders' equity and the shares are treated as treasury shares until they are subsequently sold, reissued or cancelled. Treasury shares are purchased primarily for use on vesting of employee share schemes and the DRP. Shares are accounted for at a weighted average cost. D4 Financial risk management Overview The Group's day-to-day operations, new investment opportunities and funding activities introduce financial risks, which are actively managed by the Board Risk Committee. These risks are grouped into the following categories: • Credit: The risk that a counterparty will not fulfil its financial obligations under a contract or other arrangement. • Market: The risk that fluctuations in commodity prices, foreign exchange rates and interest rates will adversely impact the Group's result. • Liquidity: The risk that the Group will not be able to meet its financial obligations as they fall due. Risk Credit Market Liquidity Sources Risk management framework Financial exposure Sale of goods and services and hedging activities The Board approves credit risk management policies that determine the level of exposures it is prepared to accept. Credit limits are allocated to counterparties based on publicly available credit information from recognised providers where available. Notes C1, C6 and D4 disclose the carrying amounts of financial assets, which represent the Group's maximum exposure to credit risk at the reporting date. The Group utilises International Swaps and Derivative Association (ISDA) agreements to limit exposure to credit risk by netting amounts receivable from and payable to individual counterparties (refer to note G8). Purchase and sale of commodities and funding risks Ongoing business obligations and new investment opportunities The Board approves policies that ensure the Group is not exposed to excess risk from market volatility. These policies include active hedging of price and volume exposures within prescribed cash flow at risk and value at risk limits. The Group centrally manages its liquidity position through cash flow forecasting and maintenance of minimum levels of liquidity determined by the Board. The debt portfolio is periodically reviewed to ensure there is funding flexibility and an appropriate maturity profile. See below for further discussion of market risk. Analysis of the Group's liquidity profile as at the reporting date is presented at the end of this section. Financial Statements 117 D4 Financial risk management (continued) Market risk The scope of the Group's operations and activities exposes it to multiple markets risks. The table below summarises these risks by nature of exposure and provides information about the risk mitigation strategies being applied. Nature Sources of financial exposure Risk management strategy Commodity price Future commercial transactions and recognised assets and liabilities exposed to changes in electricity, oil, gas, coal or environmental scheme certificate prices Foreign exchange Foreign-denominated borrowings and investments and future foreign currency denominated commercial transactions Interest rate Variable-rate borrowings (cash flow risk) and fixed-rate borrowings (fair value risk) Due to vertical integration, a significant portion of the Group's spot electricity purchases from the NEM are naturally hedged by generation sales into the NEM at spot prices. The Group manages its remaining exposure to commodity price fluctuations within Board-approved limits using a mix of commercial contracts (such as fixed-price purchase contracts) and derivative instruments (described below). The Group limits its exposure to changes in foreign exchange rates through forward foreign exchange contracts and cross-currency interest rate swaps. In certain circumstances, borrowings are left in a foreign currency, or swapped from one foreign currency to another, to hedge expected future business cash flows in that currency. Significant foreign-denominated transactions undertaken in the normal course of operations are managed on a case-by-case basis. Interest rate exposures are kept within an acceptable range as determined by the Board. Risk limits are managed through a combination of fixed-rate and fixed-to-floating interest rate swaps. Derivatives to manage market risks Derivative instruments are contracts with values that are derived from an underlying price index (or other variable) that require little or no initial net investment, and that are settled at a future date. The Group uses the following types of derivative instruments to mitigate market risk. Forwards Futures Swaps Options A contract documenting the underlying reference rate (such as benchmark price or exchange rate) to be paid or received on a notional principal obligation at a future date. An exchange-traded contract to buy or sell an asset for an agreed price at a future date. Futures are net-settled in cash without physical delivery of the underlying asset. A contract in which two parties exchange a series of cash flows for another (such as fixed-for-floating interest rate). A contract in which the buyer has the right, but not the obligation, to buy (a call option) or sell (a put option) an instrument at a fixed price in the future. The seller has the corresponding obligation to fulfil the transaction if the buyer exercises the option. Structured electricity products A non-standardised contract, generally with an energy market participant, to acquire long-term capacity. These contracts typically contain features similar to swaps and call options. Derivatives are carried on the balance sheet at fair value. Movements in the price of the underlying variables, which cause the value of the contract to fluctuate, are reflected in the fair value of the derivative. The method of recognising changes in fair value depends on whether the derivative is designated in an 'accounting' hedge relationship. Derivatives not designated as accounting hedges are referred to as 'economic' hedges. Fair value gains and losses attributable to economic hedges are recognised in the income statement and resulted in a $270 million gain (2022: $1,153 million gain) for the year. Fair value gains and losses attributable to accounting hedges are discussed in the Hedge Accounting section. 118 Annual Report 2023 D4 Financial risk management (continued) $m 2023 Economic hedges Commodity contracts Foreign exchange and interest rate contracts Total economic hedges Accounting hedges Commodity contracts Foreign exchange and interest rate contracts Total accounting hedges Total 2022 Economic hedges Commodity contracts Foreign exchange and interest rate contracts Total economic hedges Accounting hedges Commodity contracts Foreign exchange and interest rate contracts Total accounting hedges Total Hedge accounting Assets Liabilities Current Non-current Current Non-current 751 27 778 322 - 322 1,100 1,112 5 1,117 2,016 41 2,057 3,174 1,183 2 1,185 391 - 391 1,576 1,766 - 1,766 1,309 - 1,309 3,075 (706) (10) (716) (185) - (185) (901) (1,417) (48) (1,465) (125) - (125) (1,590) (1,051) (10) (1,061) (82) (31) (113) (1,174) (1,526) (3) (1,529) (161) (54) (215) (1,744) The Group uses two types of hedge accounting relationships, as detailed below. Fair value hedge Cash flow hedge Objective of hedging arrangement To hedge our exposure to changes in the fair value of a recognised asset or liability or unrecognised firm commitment, caused by interest rate or foreign currency movements. To hedge our exposure to variability in the cash flows of a recognised asset or liability, or a highly probable forecast transaction caused by commodity price, interest rate and foreign currency movements. Effective hedge portion Hedge ineffectiveness All changes in the fair value of the underlying item relating to the hedged risk and the change in fair value of derivatives are recognised in profit and loss at the same time. The effective portion of changes in the fair value of derivatives designated as cash flow hedges are recognised in the hedge reserve. Certain determinants of fair value, such as credit charges included in derivatives, or mismatches between the timing of the instrument and the underlying item in the hedge relationship, can cause hedge ineffectiveness. Any ineffectiveness is recognised immediately in profit or loss as a change in the fair value of derivatives. Hedged item sold or repaid The unamortised fair value adjustment is recognised immediately in profit or loss. Amounts accumulated in the hedge reserve are transferred immediately to profit or loss. Hedging instrument expires, is sold, is terminated or no longer qualifies for hedge accounting The unamortised fair value adjustment is recognised in profit or loss when the hedged item is recognised in profit or loss. This may occur over time if the hedged item is amortised over the period to maturity. The amount previously deferred in the hedge reserve is only transferred to profit or loss when the hedged item is also recognised in profit or loss. At 30 June 2022 and 30 June 2023 all derivatives designated in hedge accounting relationships are cash flow hedges. Financial Statements 119 D4 Financial risk management (continued) Cash flow hedges A number of derivative contracts have been designated as cash flow hedges of the Group's exposure to foreign exchange, interest rate and commodity price fluctuations. Designated derivatives include swaps, options, futures and forwards. The Group's structured electricity products, though important to the overall risk management strategy, do not qualify for hedge accounting. As such, they are not represented in the summary information below. 2023 Nominal hedge volumes FX and interest EUR 600m Electricity 13.1 TWh Hedge rates AUD/EUR 0.62; Fixed 3.2% $22-$300/MWh Propane 104k mt US$490-US$620/mt Crude oil & gas 1,406k barrels (crude oil); 11.9 tBtu (gas) US$53-US$94/bbl (ICE Brent); US$6.5-US$37.2/ MMBtu (JKM) Timing of cash flows – up to Sep 2029 Dec 2026 Oct 2024 (ICE Brent); Dec 2025 (JKM) Dec 2026 Carrying amounts - $m FX and interest Electricity Crude oil & gas Propane Hedging instrument – assets1 Hedging instrument – liabilities1 Hedge reserve2 Fair value increase/(decrease) - $m Hedging instrument Hedged item Hedge ineffectiveness3 Reconciliation of hedge reserve - $m Effective portion of hedge gains/(losses) Transfer of deferred losses/(gains) to: – Cost of sales – Finance costs Tax on above items Change in hedge reserve (post-tax) - (31) 45 (18) 18 - (19) - (30) 15 (34) 564 (198) (366) (1,918) 1,918 - 149 (59) (99) (656) 645 (11) (215) (186) (1,704) - 575 (1,344) (484) - 201 (469) - (10) 10 (19) 19 - (13) (6) - 6 (13) 1 Hedging instruments are included in the derivatives balance on the statement of financial position. 2 No hedges have been discontinued or de-designated in the current year. 3 Hedge ineffectiveness is recognised within expenses in the income statement as a change in fair value of derivatives.

Financial Statements 121 D5 Fair value of financial assets and liabilities Financial assets and liabilities measured at fair value are grouped into the following categories based on the level of observable market data used in determining that fair value: • Level 1: The fair value of financial instruments traded in active markets (such as exchange-traded derivatives and RECs) is the quoted market price at the end of the reporting period. These instruments are included in level 1. • Level 2: The fair value of financial instruments that are not traded in an active market (such as over-the-counter derivatives) is determined using valuation techniques that maximise the use of observable market data. If all significant inputs required to fair value an instrument are observable, either directly (as prices) or indirectly (derived from prices), the instrument is included in level 2. • Level 3: If one or more of the significant inputs required to fair value an instrument is not based on observable market data, the instrument is included in level 3. 2023 Derivative financial assets Other financial assets at fair value Financial assets carried at fair value Derivative financial liabilities Other financial liabilities at fair value Financial liabilities carried at fair value 2022 Derivative financial assets Other financial assets at fair value Financial assets carried at fair value Derivative financial liabilities Other financial liabilities at fair value Financial liabilities carried at fair value Note D4 C6 D4 C6 D4 C6 D4 C6 Level 1 $m 1,044 478 1,522 (592) (369) (961) Level 1 $m 1,917 623 2,540 (471) (417) (888) Level 2 $m 1,310 69 1,379 (883) - (883) Level 2 $m 3,382 73 3,455 (2,294) - (2,294) Level 3 $m 322 170 492 (600) - (600) Level 3 $m 950 74 1,024 (569) - (569) The following table shows a reconciliation of movements in the fair value of level 3 instruments during the year.

To the maximum extent possible, valuations are based on assumptions that are supported by independent and observable market data. For instruments that settle more than 12 months from the reporting date, cash flows are discounted at the applicable market yield, adjusted to reflect the credit risk of the specific counterparty. Instrument Fair value methodology Financial instruments traded in active markets Interest rate swaps and CCIRS Forward foreign exchange contracts Quoted market prices at reporting date. Present value of expected future cash flows based on observable yield curves and forward exchange rates at reporting date. Present value of future cash flows based on observable forward exchange rates at reporting date. Electricity, oil and other commodity derivatives (not traded in active markets) Present value of expected future cash flows based on observable forward commodity price curves (where available). The majority of the Group's level 3 instruments are commodity contracts for which further detail on the significant unobservable inputs is included below. Other financial instruments Discounted cash flow analysis. Long-term borrowings Present value of future contract cash flows. Future climate-related conditions, legislation and policies may have an impact on market prices. Refer to the Strategy and climate change risks section in the Overview for further analysis of the Group’s climate scenario analysis. Fair value measurements using significant unobservable inputs (level 3) The following is a summary of the Group's level 3 financial instruments, the significant inputs for which market observable data is unavailable, and the sensitivity of the estimated fair values to the assumptions applied by management. Instrument Electricity derivatives Unobservable inputs Relationship to fair value Forward electricity swap price curve Forward electricity cap price curve Forecast REC prices A 10 per cent increase/decrease in the unobservable inputs would increase/decrease fair value by $201 million (2022: $256 million). Day 1 fair value adjustments For certain complex financial instruments, such as the structured electricity products, the fair value that is determined at inception of the contract using unobservable inputs does not equal the transaction price. When this occurs, the difference is deferred to the statement of financial position and recognised in the income statement over the life of the contract in a manner consistent with the valuation methodology initially applied.

The table below reflects debt instruments reported within non-current interest-bearing liabilities on the balance sheet. Non-current lease liabilities, which are also reported within non-current interest-bearing liabilities are excluded. The fair value of these financial instruments reflects the present value of expected future cash flows based on market pricing data for the relevant underlying interest and foreign exchange rates.

The head entity within the tax-consolidated group is Origin Energy Limited. Tax funding arrangement amounts are recognised as inter-entity amounts. Income tax expense is made up of current tax expense and deferred tax expense. Current tax expense represents the expected tax payable on the taxable income for the year, using current tax rates and any adjustment to tax payable in respect of previous years. Deferred tax expense reflects the temporary differences between the accounting carrying amount of an asset or liability in the statement of financial position and its tax base. Financial Statements 125 E1 Income tax expense (continued) Key judgements and estimates Tax balances: Tax balances reflect a current understanding and interpretation of existing tax laws. Uncertainty arises due to the possibility that changes in tax law or other future circumstances can impact the tax balances recognised in the financial statements. Ultimate outcomes may vary. Deferred taxes: The recognition of deferred tax balances requires judgement as to whether it is probable such balances will be utilised and/or reversed in the foreseeable future and there will be sufficient future taxable profits against which the benefits can be utilised. A deferred tax liability is recognised for taxable temporary differences associated with investments in joint ventures unless the Group is able to control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. The deferred tax liability in respect of the investment in APLNG represents carried forward equity accounted earnings that are expected to be distributed to Origin via dividends from APLNG in the foreseeable future. In determining the forecast distributions from APLNG, the Group’s assessment of future cash flows considers a range of macroeconomic and project assumptions, including oil and LNG prices, AUD/USD exchange rates, discount rates and costs over the asset's life. At 30 June 2023, the Group has recognised a deferred tax liability of $528 million. The remaining unbooked balance is not expected to reverse in the foreseeable future through the payment of future dividends, through sale or through a capital return. The unrecognised portion is disclosed in note E2.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the year when the asset is realised or the liability is settled, based on tax rates and tax laws that have been enacted or substantively enacted at the balance sheet date. A deferred tax asset is recognised only to the extent that it is probable that future taxable profits will be available against which the asset can be utilised. Deferred tax assets are reduced if it is no longer probable that the related tax benefit will be realised. 126 Annual Report 2023 E2 Deferred tax (continued) Movement in temporary differences during the year 1 July 2021 Recognised in income Recognised in equity Acquisition of subsidiary 30 June 2022 Recognised in income Recognised in equity Recognised in current tax liability Asset/(liability) $m Employee benefits Provisions Tax value of carry-forward tax losses recognised PP&E Exploration and evaluation assets Financial instruments at fair value Investment in APLNG APLNG MRCPS elimination (refer to note B2.2) Business-related costs (deductible under s.40-880 ITAA97) ROU assets Lease liabilities Intangibles Other items Net deferred tax liabilities 80 430 1 (215) (67) 347 (669) 4 (17) - 36 (13) (397) (39) 48 (15) 26 (121) 139 1 (5) (5) (20) (18) 22 1 3 - 10 - - - (886) - - - - - - - - - - - - - - - - - - (25) - 84 423 1 (179) (80) (936) (708) 33 6 (139) 161 (23) (2) 14 (114) - 41 78 (40) 180 - 4 (1) 3 1 (2) (453) (876) (25) (1,359) 164 30 June 2023 98 314 1 (138) (2) (179) (528) 33 10 (140) 164 (22) 3 (386) - 5 - - - 797 - - - - - - 3 805 - - - - - - - - - - - - 4 4 Unrecognised deferred tax assets and liabilities Deferred tax assets have not been recognised in respect of the following items: Revenue losses - non-Australian Petroleum resource rent tax, net of income tax Acquisition transaction costs Intangible assets Deferred tax liabilities have not been recognised in respect of the following items: Investment in APLNG1 2023 $m 2022 $m 4 119 57 8 188 5 119 57 8 189 (759) (759) (685) (685) 1 The deferred tax liability in respect of the investment in APLNG has not been recognised in full during the year as not all of the temporary difference is expected to reverse in the foreseeable future.

F2 Business combinations There were no significant business combinations during the year. F3 Joint arrangements and investments in associates Joint arrangements are entities over whose activities the Group has joint control, established by contractual agreement and requiring the consent of two or more parties for strategic, financial and operating decisions. The Group classifies its interests in joint arrangements as either joint operations or joint ventures, depending on its rights to the assets and obligations for the liabilities of the arrangements. Associates are entities, other than partnerships, for which the Group exercises significant influence, but no control, over the financial and operating policies, and which are not intended for sale in the near future. Of the Group's interests in joint arrangements and associates, only APLNG and Octopus Energy have a material impact on the Group at 30 June 2023 (refer to Section B). Interests in unincorporated joint operations The Group's interests in unincorporated joint operations are brought to account on a line-by-line basis in the income statement and statement of financial position. These interests are held on the following assets whose principal activities are oil and/or gas exploration, development and production; power generation; and geothermal power technology: • Browse Basin • Innamincka Deeps Geothermal • Cooper-Eromanga Basin 130 Annual Report 2023 F4 Assets and liabilities held for sale and disposals Assets and liabilities held for sale LPG Pacific On 8 November 2022 the Group entered into an agreement to sell Origin’s LPG business in the Pacific. This includes the Group's wholly-owned entities in Vanuatu, American Samoa, Samoa and Cook Islands, and controlled entities in Fiji, Papua New Guinea and the Solomon Islands. There are a number of conditions and regulatory approvals required before the sale can be completed and the assets and liabilities relating to the sale have been classified as held for sale as at 30 June 2023. Canning Basin On 10 February 2023 Origin executed an agreement with Buru Energy Limited (Buru) to exit from its participating interests in the seven Exploration Permits in the Canning Basin, the respective Joint Operating Agreements and the Farm-in Agreements. The terms of the sale provide for Origin to provide Buru with up to $4 million to fund a seismic survey and for Buru to provide Origin with future reimbursement payments of up to $34 million, conditional on the achievement of key development and production milestones. Settlement of the transaction remains subject to regulatory approvals.

Completion of the transaction occurred on 9 November 2022 for upfront consideration of $60 million and a royalty based on wellhead revenues produced from the three Beetaloo permits. This resulted in a pre-tax loss on disposal of $106 million. Origin Energy Hydro Bermuda Pty Limited On 10 January 2023 Origin Energy Hydro Bermuda Pty Limited was wound up. A net gain on disposal of $62 million was recycled to the income statement from the foreign currency translation reserve on wind up. Financial Statements 131 G Other information This section includes other information to assist in understanding the financial performance and position of the Group, and items required to be disclosed to comply with accounting standards and other pronouncements. G1 Contingent liabilities Discussed below are items where there is a possible obligation whose existence will be confirmed only by uncertain future events not wholly within the Group’s control, or where a present obligation exists, it is either not probable that the Group will have to make future payments, or the amount of future payments is not capable of reliable measurement. Joint arrangements and associates As a participant in certain joint arrangements, the Group is liable for its share of liabilities incurred by these arrangements. In some circumstances, the Group may incur more than its proportionate share of such liabilities but will have the right to recover the excess liability from the other joint arrangement participants. In October 2018, Origin and the other APLNG shareholders agreed to indemnify one of APLNG’s long-term LNG customers (following that customer's election to defer delivery of 30 cargoes over six years (2019-24)) should APLNG fail to supply make-up cargoes to that customer prior to the expiry of the LNG supply contract. The customer will pay APLNG for the deferred cargoes and APLNG expects to resell the gas to other customers and deliver the deferred cargoes to the long-term LNG customer between 2025 and the end of the LNG supply contract. The indemnity was provided severally in accordance with each shareholder’s proportionate shareholding in APLNG. At the inception of the agreement, any obligation or liability on the part of the shareholders will only be confirmed by the occurrence or non-occurrence of future events. Legal and regulatory Certain entities within the Group (and joint venture entities, such as APLNG) are subject to various lawsuits and claims as well as audits and reviews by government, regulatory bodies or other joint venture partners. In most instances, it is not possible to reasonably predict the outcome of these matters or their impact on the Group and accordingly is not probable that future payments will be made. Where outcomes can be reasonably predicted, provisions are recorded. A number of sites owned/operated (or previously owned/operated) by the Group have been identified as potentially contaminated. For sites where it is likely that a present obligation exists, and it is probable that an outflow of resource will be required to settle the obligation, such costs have been expensed or provided for. Warranties and indemnities have also been given and/or received by entities in the Group in relation to environmental liabilities for certain properties divested and/or acquired. Capital expenditure As part of the acquisition of Browse Basin exploration permits in 2015, the Group agreed to pay cash consideration of US$75 million contingent upon a project Final Investment Decision (FID), and US$75 million contingent upon first production. The Group will pay further contingent consideration of up to US$50 million upon first production if 2P reserves, at the time of the FID, reach certain thresholds. These obligations have not been provided for at the reporting date as they are possible obligations that are dependent upon uncertain future events not wholly within the Group’s control. Bank guarantees There are no contingent liabilities arising from bank guarantees held by the Group that are required to be disclosed as at the reporting date, as these have either been provided for, or an outflow of economic benefits is considered remote. The Group's share of guarantees for certain contractual commitments of its joint ventures is shown at note G2. 132 Annual Report 2023 G2 Commitments Detailed below are the Group's contractual commitments that are not recognised as liabilities as there is no present obligation. Capital expenditure commitments Joint venture commitments1 2023 $m 786 183 2022 $m 108 237 1 Includes $180 million (2022: $121 million) in relation to the Group's share of APLNG’s capital and joint venture commitments. G3 Share-based payments This section sets out details of the Group's share-based remuneration arrangements, including details of the Company's Equity Incentive Plan and Employee Share Plan (ESP). The table below shows share-based remuneration expenses that were recognised during the year. Equity Incentive Plan Employee Share Plan Total 2023 $m 25 1 26 2022 $m 29 4 33 Equity Incentive Plan Eligible employees are granted share-based remuneration under the Origin Energy Limited Equity Incentive Plan. Participation in the plan is at the Board’s discretion and no individual has a contractual right to participate or to receive any guaranteed benefits. Equity incentives granted prior to FY2018 were offered in the form of Options and/or Share Rights. From FY2019 onwards, equity incentives are granted in the form of Share Rights and/or Restricted Shares (RSs). Only RSs carry dividend and voting entitlements. To the extent that Share Rights ultimately vest, a dividend equivalent mechanism operates. (i) Short Term Incentive Short Term Incentive (STI) includes the award of RSs, which are subject to trading restrictions for a set period of time (generally up to two years), after which they become unrestricted, provided that the employee remains employed with satisfactory performance. Once unrestricted, the shares are transferred into the employee's name at no cost. The face value of RSs measured at grant date is recognised as an employee expense over the related service period. RSs are forfeited if the service and performance conditions are not met.3 (ii) Long Term Incentive The Long Term Incentive (LTI) awards include the award of Share Rights, which vest subject to performance conditions. Generally, half of each LTI award is made in the form of Performance Share Rights (PSRs) and is subject to a market hurdle, namely Origin’s Total Shareholder Return (TSR) relative to a Reference Group of ASX-listed companies, as identified in the 2023 Remuneration Report. The remaining half of each LTI award is made in the form of Restricted Share Rights (RSRs), where vesting is subject to Board assessment with reference to a suite of underpinning conditions, as set out in the 2023 Remuneration Report. The number of awards that may vest are considered separately for PSRs and RSRs. For the PSR awards, which are subject to the relative TSR hurdle, vesting only occurs if Origin’s TSR over the performance period ranks higher than the 50th percentile of the Reference Group. Half of the PSRs vest if that condition is satisfied. All the PSRs vest if Origin ranks at or above the 75th percentile of the Reference Group. Straight-line pro-rata vesting applies in between these two points. The PSR grants made in FY2023 have a performance period of three years. Vesting is into RSs with a trading restriction for a further two years (total deferral five years). For the RSR awards, the Board will determine the vesting outcome shortly before each of three progressive vesting dates at years three, four and five by reference to a broad range of performance indicators. Vesting is into RSs which all have trading restrictions until the end of the fifth year. Prior to FY2021, the LTI awards include the award of PSRs, such that half of the award is subject to the TSR hurdle, and the remaining half of each LTI award is subject to an internal hurdle, namely Return on Capital Employed (ROCE), as set out in the relevant remuneration report. For awards granted in FY2020 that are subject to the ROCE hurdle, half of the ROCE tranche is allocated to Energy Markets and the other half to Integrated Gas. Each tranche is tested separately and vest separately. Vesting for each tranche only occurs if the average actual annual ROCE outcomes over the performance period for the relevant business meets or exceeds the average of the annual ROCE targets, which are reflective of delivering WACC for the relevant business. Half of the relevant PSRs will vest if the ROCE target is met. All the relevant PSRs vest if the ROCE target is exceeded by two percentage points or more. Straight-line pro-rata vesting applies in between. The last tranche of these PSRs that were subject to the ROCE hurdle, vested in FY2023. The LTI awards granted after FY2020 are no longer subject to the ROCE hurdle. Vested share rights are automatically exercised upon vesting, and there is no exercise price. Upon exercise, a vested award is converted into one fully paid ordinary share that is subject to a post-vesting holding lock for a set period (generally up to two years) and carries voting and dividend entitlements. 3 The Equity Incentive Plan Rules set out exceptional circumstances, such as death, disability, redundancy or genuine retirement, (‘good leaver’ circumstances) under which RSs are released at cessation unless the Board determines otherwise. Financial Statements 133 G3 Share-based payments (continued) In relation to Share Rights awarded since FY2021, upon vest, a dividend equivalent amount will be delivered in the form of additional shares equal in value (as determined by the Board) to the amount of dividends that would have been paid and re-invested had the participant held the underlying shares during the period from the grant date through to the relevant vesting date. The fair value of the awards granted is recognised as an employee expense, with a corresponding increase in equity, over the vesting period. In exceptional circumstances4, unvested Share Rights may be held ‘on foot’ subject to the specified performance hurdles and other plan conditions being met, or dealt with in an appropriate manner determined by the Board. For PSRs subject to the relative TSR condition, fair value is measured at grant date using a Monte Carlo simulation model that takes into account the exercise price, share price at grant date, price volatility, dividend yield, risk-free interest rate for the term of the security, and the likelihood of meeting the TSR market condition. The expected volatility reflects the assumption that the historical volatility over a period similar to the life of the options is indicative of future trends, which may not necessarily be the actual outcome. The amount recognised as an expense is adjusted to reflect the actual number of awards that vest except where due to non-achievement of the TSR market condition. Set out below are the inputs used to determine the fair value of the PSRs granted during the year. For RSRs subject to the underpinning conditions, the initial fair value at grant date is the market value of an Origin share, and the recognised expense is trued up at each reporting period to the expected outcome as assessed at that time. Set out below is a summary of RSRs and PSRs issued during the financial year. Grant date Grant date share price Exercise price Volatility Risk-free rate1 RSRs RSRs PSRs PSRs 05 Sep 2022 19 Oct 2022 05 Sep 2022 19 Oct 2022 $6.13 Nil - - $5.64 Nil - - $6.13 Nil 38% 3.29% $3.63 $5.64 Nil 38% 3.48% $3.17 Grant date fair value (per award) $6.13 $5.64 1 Where the risk-free rate is nil, these RSR tranches are subject to a number of underpinning conditions to be assessed by the Board; therefore, the risk-free rate is not relevant to their valuation.

The options outstanding as at 30 June 2023 were tested on 30 June 2023; they did not satisfy the vesting conditions and lapsed on 22 August 2023 in accordance with the Equity Incentive Plan rules. For more information on these share plans and performance rights issued to key management personnel, refer to the Remuneration Report. 4 The Equity Incentive Plan Rules provide that Share Rights, and RSs arising from STI arrangements, are forfeited on cessation of employment, except in ‘good leaver’ circumstances or unless the Board determines otherwise. The offer terms provide guidance for the exercise of that discretion, specifically that the Share Rights and RSs will not normally be forfeited in cases of 'good leavers' (such as those ceasing employment due to death, disability, redundancy or genuine retirement). 134 Annual Report 2023 G3 Share-based payments (continued) Employee Share Plan Under the ESP, all eligible employees have a choice of either participating in the $1,000 General Employee Share Plan (GESP) or the Matching Share Plan (MSP). As a result of entering into the binding Scheme Implementation Deed with the Consortium, the operation of the ESP has been suspended from 31 March 2023 and no awards under the ESP are expected to be made during FY2024. Under the GESP, all employees of the Company who are based in Australia and have been continuously employed as at 1 March of the performance year, are granted up to $1,000 of fully paid Origin shares conditional on Board approval. The shares are granted for no consideration. Shares awarded under the GESP are purchased on market, registered in the name of the employee, and are restricted for three years, or until cessation of employment, whichever occurs first. Under the MSP, all eligible employees may elect to purchase shares via a salary sacrifice arrangement, which commences on 1 October of the performance year. The shares under this plan are allotted quarterly and are subject to a trading restriction for a set period (generally two years) or until cessation of employment. The Company matches the purchased shares on a one-for-two basis with allocation of additional Matching Rights (MRs) which vest at the same time as the restriction is lifted for the purchased shares. Vesting of MRs is conditional on the employee remaining in continuous employment at that time. MRs are forfeited if the service conditions are not met.5 Details of the shares awarded under the GESP during the year are set out below. The cost per share represents the weighted average market price of the Company's shares on the grant date. 2023 2022 Grant date 29 Aug 2022 6 Sep 2021 Shares granted 587,972 587,972 813,637 813,637 Cost per share $6.18 $4.36 Total Total Set out below is a summary of MRs outstanding at the beginning and end of the financial year.

In general, under such agreements the amounts owed by each counterparty on a single day in respect of all transactions outstanding in the same currency are aggregated into a net amount payable by one party to the other. Financial assets and liabilities are offset, and the net amount reported in the statement of financial position, where the Group has a legally enforceable right to offset recognised amounts and there is an intention to settle on a net basis or realise the asset and settle the liability simultaneously. The Group has also entered into arrangements that do not meet the criteria for offsetting, but still allow for the related amounts to be offset in certain circumstances, such as a loan default or the termination of a contract. The following table presents the recognised financial instruments that are offset, or subject to master netting arrangements but not offset, as at the reporting date. The net amount column shows the impact on the Group's statement of financial position if all set-off rights were exercised. 2023 Derivative assets Derivative liabilities 2022 Derivative assets Derivative liabilities Amount offset in the statement of financial position $m Amount in the statement of financial position $m Related amount not offset $m Gross amount $m 4,109 (3,508) 9,855 (6,940) (1,433) 1,433 (3,606) 3,606 2,676 (2,075) 6,249 (3,334) (1,041) 1,041 (2,070) 2,070 Net amount $m 1,635 (1,034) 4,179 (1,264) G9 Deed of Cross Guarantee The parent entity has entered into a Deed of Cross Guarantee through which the Group guarantees the debts of certain controlled entities in the event that one of those entities is wound up.

Signed in accordance with a resolution of the Directors: Scott Perkins Chairman Frank Calabria Managing Director and Chief Executive Officer Sydney, 17 August 2023 Sydney, 17 August 2023 142 Annual Report 2023 Independent Auditor’s Report A member firm of Ernst & Young Global Limited Liability limited by a scheme approved under Professional Standards Legislation Ernst & Young 200 George Street Sydney NSW 2000 Australia GPO Box 2646 Sydney NSW 2001 Tel: +61 2 9248 5555 Fax: +61 2 9248 5959 ey.com/au Independent Auditor’s Report to the Members of Origin Energy Limited Report on the Audit of the Financial Report Opinion We have audited the financial report of Origin Energy Limited (the Company) and its subsidiaries (collectively the Group), which comprises the consolidated statement of financial position as at 30 June 2023, the consolidated income statement, the consolidated statement of comprehensive income, consolidated statement of changes in equity and consolidated statement of cash flows for the year then ended, notes to the financial statements, including a summary of significant accounting policies, and the directors’ declaration. In our opinion, the accompanying financial report of the Group is in accordance with the Corporations Act 2001, including: a. Giving a true and fair view of the consolidated financial position of the Group as at 30 June 2023 and of its consolidated financial performance for the year ended on that date; and b. Complying with Australian Accounting Standards and the Corporations Regulations 2001. Basis for Opinion We conducted our audit in accordance with Australian Auditing Standards. Our responsibilities under those standards are further described in the Auditor’s responsibilities for the audit of the financial report section of our report. We are independent of the Group in accordance with the auditor independence requirements of the Corporations Act 2001 and the ethical requirements of the Accounting Professional and Ethical Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) that are relevant to our audit of the financial report in Australia. We have also fulfilled our other ethical responsibilities in accordance with the Code. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. Key Audit Matters Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the financial report of the current year. These matters were addressed in the context of our audit of the financial report as a whole, and in forming our opinion thereon, but we do not provide a separate opinion on these matters. For each matter below, our description of how our audit addressed the matter is provided in that context. We have fulfilled the responsibilities described in the Auditor’s responsibilities for the audit of the financial report section of our report, including in relation to these matters. Accordingly, our audit included the performance of procedures designed to respond to our assessment of the risks of material misstatement of the financial report. The results of our audit procedures, including the procedures performed to address the matters below, provide the basis for our audit opinion on the accompanying financial report. Financial Statements 143 A member firm of Ernst & Young Global Limited Liability limited by a scheme approved under Professional Standards Legislation Carrying Value of the Energy Markets Group of Cash Generating Units (CGUs) Why significant How our audit addressed the key audit matter In accordance with the requirements of Australian Accounting Standards, the Group is required to test all CGUs annually for impairment where goodwill is present. Where no goodwill is present, the Group must assess for indicators of impairment and impairment reversal each reporting period. The Group assesses the recoverable amount of each CGU using a discounted cash flow forecast to determine value in use. No impairment loss or reversal of impairment across any of the Energy Market CGUs was recognised during the year. The carrying value of the Energy Markets Group of CGUs is significant at 30 June 2023. As disclosed in Note C7, assumptions used in the forecasting of cash flows require significant judgment. In particular the forecasting of long-term energy and commodity price assumptions is subjective and complex in nature. As a result of the significance of the carrying value and inherent judgment and complexity in the cash flow forecasts we considered the recoverability of the carrying value of the Energy Markets group of CGUs and the related disclosures in the financial report to be significant to our audit. Our audit procedures included the following: • Considered whether indicators of impairment or impairment reversal were present for each of the three CGUs within the Energy Markets Group of CGUs. • Assessed whether the methodology applied by the Group in testing the recoverable amount of each CGU met the requirements of Australian Accounting Standards. • Assessed the basis for the determination of the Group’s CGUs based on our understanding of the nature of the Group’s business, the interdependence of cash flows, and the economic environment in which it operates. • Tested the mathematical accuracy of the discounted cash flow models. • Assessed the cash flow forecasts with reference to historical budgeting accuracy and current trading performance, historical growth rates, historical operating results, market data and forecasts, ratio analysis, and discussions with management and senior executives. • Where long term supply or sales contracts are in place, agreed the forecast revenue and costs to the contract terms and rates. • For the Generation CGU within the Energy Markets Group of CGUs, compared the useful lives of assets assumed in the impairment model to the Australian Energy Market Operator (“AEMO”) closure dates. • Involved our energy market modelling specialists to assess the conclusions reached by the Group’s internal specialists in respect of forecast energy prices, forecast generation volumes, forecast capacity prices and marginal loss factors. • Involved our valuation specialists to: o Assess the discount rates and terminal growth rates with reference to publicly available information on comparable companies in the industry and markets in which the Group operates; and o Perform sensitivity analyses and evaluate the impact of reasonably possible changes in assumptions on the recoverable amount. • Cross checked the Group’s net assets to other available information including market capitalisation and the Binding Scheme Implementation Deed signed on 27 March 2023. • Considered the potential impacts of climate risk on the recoverable amount by analysing the forecast energy price assumptions applied by management, asset useful lives and the possible changes to commodity prices resulting from the transition to a low carbon future. • Evaluated the adequacy of the related disclosure in the financial report. 144 Annual Report 2023 A member firm of Ernst & Young Global Limited Liability limited by a scheme approved under Professional Standards Legislation Carrying Value of APLNG Equity Accounted Investment Why significant How our audit addressed the key audit matter At 30 June 2023, the Group’s equity accounted investment in Australia Pacific LNG Pty Limited (APLNG) had a carrying value of $5,469 million. No impairment or impairment reversal was recorded. As disclosed in Note B2.2, the carrying amount of the Group's equity accounted investment in APLNG is reviewed at each reporting date to determine whether there is any indicators of impairment or impairment reversal. Where an indicator of impairment or impairment reversal exists, a formal estimate of the recoverable amount is made. Oil price is a significant assumption used in this assessment and is inherently subjective. Changes in this assumption can lead to significant changes in the recoverable amount. Due to the significance of this investment relative to total assets and the inherent complexity in forecasting commodity prices and future market outlooks, we considered the carrying value of this investment to be a key audit matter. In fulfilling our responsibilities as Group auditor, we considered the work performed by the EY Component Auditor responsible for auditing APLNG, which includes auditing the carrying value of APLNG’s assets at the Joint Venture level. These oversight procedures included: • Sending instructions to the EY Component Auditor detailing the scope to be covered for the purposes of our audit of the Group. This included the risk associated with impairment or impairment reversal. • The Component Auditor confirmed compliance with the instructions provided and reported the results of their procedures to us. • To ensure sufficient oversight, we, as the Group audit team: o Held frequent meetings with the Component Auditor to discuss the outcome and extent of their procedures. o Reviewed underlying working papers and documentation of the Component Auditor for selected areas of audit focus. In addition, we undertook the following additional procedures with the assistance of our valuations specialists: • Considered whether information existed that was contrary to the EY Component auditor’s conclusion in respect of the existence of impairment or impairment reversal for APLNG at 30 June 2023 and may represent objective evidence of a significant or prolonged change in value of the investment, including: o Considered changes to market conditions during the period including changes and volatility in key macro-economic assumptions such as oil price and gas price with reference to broker and analyst data and publicly available peer company information. o Evaluated possible changes to the APLNG discount rate with reference to external market data including government bond rates and comparable company data. o Considered the impact of climate risk on the asset life and key macro-economic assumptions. o Undertook sensitivity analysis for reasonably possible changes in key assumptions which included price sensitivity analysis using scenarios developed by the International Energy Agency. • Considered available market information including trading and reserve multiples as a cross check of the carrying value of the Group’s equity accounted investment. • Assessed the climate related disclosures in respect of APLNG for accuracy and consistency with other publicly disclosed information. Financial Statements 145 A member firm of Ernst & Young Global Limited Liability limited by a scheme approved under Professional Standards Legislation Unbilled Revenue Why significant How our audit addressed the key audit matter At 30 June 2023, the Group recognised unbilled revenue net of an allowance for impairment of $1,457 million as disclosed in Note A2 and C1. Unbilled revenue represents the value of energy supplied to customers between the date of the last meter read and the reporting date where no bill has been issued to the customer at the end of the reporting period. The estimation of unbilled revenue is considered a key audit matter due to the complex estimation process and significant audit effort required to address the estimation uncertainty. Key factors that require consideration impacting the complex estimation process include: • Estimation of customer demand and energy consumption, which is impacted by weather, an individual customer’s circumstances and market volatility. • Application of different customer rates across different regulated and unregulated markets. The Group’s disclosures in respect of the unbilled revenue estimation process are included in Notes A2 and C1 of the financial report. Our audit procedures included the following: • Assessed whether the methodology used to recognise unbilled revenue met the requirements of Australian Accounting Standards. • Assessed the effectiveness of the Group’s controls governing energy purchased, energy sold and the customer pricing process. • Evaluated the unbilled revenue calculation as follows: o With the assistance of our data analytics specialists, assessed the calculation methodology of the unbilled revenue model. o Compared inputs used in the calculation to supporting data such as historical temperature data, volume data provided by the Australian Energy Market Operator (AEMO) and solar-feed-in data. o Tested the reasonableness of the Group’s allocation of energy consumed to residential and small and medium enterprises (“SME”) with reference to historical billing data. o Compared the prices applied to unbilled customer consumption with historical and current billing data. o Reviewed the Group’s reconciliation of volumes acquired from AEMO against volumes sold and volumes purchased as used by the Group in their analysis. o Compared the historical accuracy of the unbilled revenue accrual by comparing the historical accrual to final billing data and performing a trend analysis of the accrual year on year. o Tested the accuracy of the unbilled revenue accrual for business customers by comparing the unbilled revenue accrual to subsequent invoices. • Evaluated the adequacy of the related disclosures in the financial report including those made with respect to judgements and estimates Information Other than the Financial Report and Auditor’s Report Thereon The directors are responsible for the other information. The other information comprises the information included in the Company’s 2023 annual report, but does not include the financial report and our auditor’s report thereon. Our opinion on the financial report does not cover the other information and accordingly we do not express any form of assurance conclusion thereon. 146 Annual Report 2023 A member firm of Ernst & Young Global Limited Liability limited by a scheme approved under Professional Standards Legislation In connection with our audit of the financial report, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial report or our knowledge obtained in the audit or otherwise appears to be materially misstated. 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 for the Financial Report The directors of the Company are responsible for the preparation of the financial report that gives a true and fair view in accordance with Australian Accounting Standards and the Corporations Act 2001 and for such internal control as the directors determine is necessary to enable the preparation of the financial report that gives a true and fair view and is free from material misstatement, whether due to fraud or error. In preparing the financial report, the directors are responsible for assessing the Group’s ability to continue as a going concern, disclosing, as applicable, matters relating to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the Group or to cease operations, or have no realistic alternative but to do so. Auditor’s responsibilities for the audit of the financial report Our objectives are to obtain reasonable assurance about whether the financial report as a whole is 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 the Australian Auditing Standards 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 this financial report. As part of an audit in accordance with the Australian Auditing Standards, we exercise professional judgment and maintain professional scepticism throughout the audit. We also: ► Identify and assess the risks of material misstatement of the financial report, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. ► Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s internal control. ► Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the directors. ► Conclude on the appropriateness of the directors’ use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the financial report or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s Financial Statements 147 A member firm of Ernst & Young Global Limited Liability limited by a scheme approved under Professional Standards Legislation report. However, future events or conditions may cause the Group to cease to continue as a going concern. ► Evaluate the overall presentation, structure and content of the financial report, including the disclosures, and whether the financial report represents the underlying transactions and events in a manner that achieves fair presentation. ► Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the financial report. We are responsible for the direction, supervision and performance of the Group audit. We remain solely responsible for our audit opinion. We communicate with the directors regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit. We also provide the directors with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, actions taken to eliminate threats or safeguards applied. From the matters communicated to the directors, we determine those matters that were of most significance in the audit of the financial report of the current year and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication. Report on the Audit of the Remuneration Report Opinion on the Remuneration Report We have audited the Remuneration Report included in the directors’ report for the year ended 30 June 2023. In our opinion, the Remuneration Report of Origin Energy Limited for the year ended 30 June 2023, complies with section 300A of the Corporations Act 2001. Responsibilities The directors of the Company are responsible for the preparation and presentation of the Remuneration Report in accordance with section 300A of the Corporations Act 2001. Our responsibility is to express an opinion on the Remuneration Report, based on our audit conducted in accordance with Australian Auditing Standards.

Origin does maintain an override royalty over the permits. Refer to ASX Announcement, dated 9 November 2022. Origin completes sale of Beetaloo interest - Origin Energy Annual Reserves Report 155 Appendix A: APLNG reserves and resources Origin, as APLNG upstream operator, has prepared estimates of the reserves and resources held by APLNG for operated assets detailed in this report. Netherland, Sewell & Associates, Inc. (NSAI) has prepared a consolidated report of the reserves and resources held by APLNG for non-operated assets. The reserves and resources estimates for the non-operated properties in their report have been independently estimated by NSAI. The tables below provide 1P, 2P and 3P reserves and 2C resources for APLNG (100 per cent) and Origin’s 27.5 per cent interest in these APLNG (operated and non-operated) reserves and resources. Reserves and resources held by APLNG (100 per cent share) Reserves/resource classification 30 June 2022 1P (proven) 2P (proven plus probable) 3P (proven plus probable plus possible) 2C (best estimate contingent resource) 7,265 11,448 12,408 3,683 Acquisition/ divestment New booking/ discovery Revisions/ extensions Production 30 June 2023 - - - - - - - - 370 175 256 46 (674) (674) (674) - 6,961 10,949 11,991 3,729 Reserves and resources held by Origin (27.5 per cent in APLNG) Reserves/resource classification 30 June 2022 Acquisition/ divestment New booking/ discovery Revisions/ extensions Production 30 June 2023 1P (proven) 2P (proven plus probable) 3P (proven plus probable plus possible) 2C (best estimate contingent resource) 1,998 3,148 3,412 1,013 - - - - - - - - 102 48 70 13 (185) (185) (185) - 1,914 3,011 3,297 1,025 See details above for movements in 1P and 2P reserves. The 256 PJ increase in APLNG (100 per cent share) 3P reserves, excluding production is primarily due to improved recovery estimates in the non-operated Kenya field due to strong field performance. Various other adjustments to other operated and non-operated field recovery estimates have a minor impact on the overall 3P reserves position. 156 Annual Report 2023 Appendix B: Notes relating to this report for downstream transport and processing. This price is exposed to changes in the supply/demand balance in the market through oil price-linked LNG contracts. a. Methodology regarding reserves c. Reversionary rights and resources The Reserves Report has been prepared to be consistent with the Petroleum Resources Management System (PRMS) 2018 published by the Society of Petroleum Engineers (SPE). This document may be downloaded from the SPE website: https://www.spe.org/en/industry/ reserves/. Additionally, this Reserves Report has been prepared to be consistent with the ASX reporting guidelines. For all assets, Origin reports reserves and resources consistent with SPE guidelines as follows: proved reserves (1P); proved plus probable reserves (2P); proved plus probable plus possible reserves (3P) and best estimate contingent resource (2C). Reserves must be discovered, recoverable, commercial and remaining. The CSG reserves and resources held within APLNG’s properties have either been independently prepared by NSAI or prepared by Origin. The reserves and resources estimates contained in this report have been prepared in accordance with the standards, definitions and guidelines contained within the PRMS and generally accepted petroleum engineering and evaluation principles as set out in the SPE Reserves Auditing Standards. Origin does not intend to report prospective or undiscovered resources as defined by the SPE in any of its areas of interest on an ongoing basis. b. Economic test for reserves The assessment of reserves requires a commercial test to establish that reserves can be economically recovered. Within the commercial test, operating cost and capital cost estimates are combined with fiscal regimes and product pricing to confirm the economic viability of producing the reserves. Gas reserves are assessed against existing contractual arrangements and local market conditions, as appropriate. In the case of gas reserves where contracts are not in place, a forward price scenario based on monetisation of the reserves through domestic markets has been used, including power generation opportunities, direct sales to LNG and other end users, and utilisation of Origin’s wholesale and retail channels to market. For CSG reserves that are intended to supply the APLNG CSG to LNG project, the economic test is based on a weighted average price across domestic, spot and LNG contracts, less short run marginal costs e. Rounding Information on reserves is quoted in this report rounded to the nearest whole number. Some totals in tables in this report may not add due to rounding. Items that round to zero are represented by the number 0, while items that are actually zero are represented with a dash "-". f. Abbreviations bbl Tscf CSG kbbls barrel trillion standard cubic feet coal seam gas kilo barrels = 1,000 barrels ktonnes kilo tonnes = 1,000 tonnes mmboe million barrels of oil equivalent PJ PJe petajoule = 1 x 1015 joules petajoule equivalent g. Conversion factors for PJe CSG 1.038 PJ/Bscf The CSG interests that APLNG acquired from Tri-Star in 2002 are subject to reversionary rights. If triggered, these rights will require APLNG to transfer back to Tri-Star a 45 per cent interest in those CSG interests for no additional consideration. Origin has assessed the potential impact of these reversionary rights, based on economic tests consistent with the reserves and resources referable to the CSG interests, and based on that assessment does not consider that the existence of these reversionary rights impacts the reserves and resources quoted in this report. Tri-Star has commenced proceedings against APLNG claiming that reversion has occurred. APLNG denies that reversion has occurred and is defending the claim.1 d. Information regarding the preparation of this Reserves Report h. Reference point The CSG reserves and resources held within APLNG’s properties have either been independently prepared by NSAI or by Origin. All assessments are based on technical, commercial and operational data provided by Origin on behalf of APLNG. The statements in this Report relating to reserves and resources as at 30 June 2023 for APLNG’s interests in non-operated assets are based on information in the NSAI report dated 3 August 2023. The data has been compiled by Mr John Hattner, a full- time employee of NSAI. Mr Hattner has consented to the statements based on this information, and to the form and context in which these statements appear. The statements in this Report relating to reserves and resources for other assets are based on, and fairly represent, information and supporting documentation prepared by, or under the supervision of qualified petroleum reserves and resource evaluators who are employees of Origin. This Reserves Statement as a whole has been approved by Mr Alistair Jones CPEng NER MIEAust who is a full-time employee of Origin. Mr Alistair Jones is Chief Reservoir Engineer, a qualified petroleum reserves and resources evaluator and a member of the Society of Petroleum Engineers, has consented to the form and context in which these statements appear. Reference points for Origin’s petroleum reserves and contingent resources are defined points within Origin’s operations where normal exploration and production business ceases, and quantities of the produced product are measured under defined conditions prior to custody transfer. Fuel, flare and vent consumed to the reference points are excluded. i. Preparing and aggregating petroleum resources Petroleum reserves and contingent resources are typically prepared by deterministic methods with support from probabilistic methods. Petroleum reserves and contingent resources are aggregated by arithmetic summation by category and as a result, proved reserves may be a conservative estimate due to the portfolio effects of the arithmetic summation. Proved plus probable plus possible may be an optimistic estimate due to the same aforementioned reasons. j. Methodology and internal controls The reserves estimates undergo an assurance process to ensure that they are technically reasonable given the available data and have been prepared according to our reserves and resources process, which includes adherence to the PRMS Guidelines. The assurance process includes peer reviews of the technical and commercial assumptions.
