Basis of preparation	1. Basis of preparation This general purpose Financial Report for the half year ended 31 December 2022 is unaudited and has been prepared in accordance with IAS 34 ‘Interim Financial Reporting’ as issued by the International Accounting Standards Board (IASB) and AASB 134 ‘Interim Financial Reporting’ as issued by the Australian Accounting Standards Board (AASB) and the Australian Corporations Act 2001 as applicable to interim financial reporting. The general purpose Financial Report for the half year ended 31 December 2022 does not include all of the notes of the type normally included in an annual report. Accordingly, this report Segment Reporting disclosures from IAS 34/AASB 134 ‘Interim Financial Reporting’ have been disclosed within the Segment summary on page 15 outside of this Financial Report. The half year Financial Statements have been prepared on a basis of accounting policies and methods of computation consistent with those applied in the 30 June 2022 annual consolidated Financial Statements contained within the Annual Report of the Group with the exception of the adoption of an All amounts are expressed in US dollars unless otherwise stated. The Group’s presentation currency and the functional currency of the majority of its operations is US dollars as this is the principal currency of the economic environment in which it operates. Amounts in this Financial Report have, unless otherwise indicated, been rounded to the nearest million dollars. The Directors Impact of new and amended standards and interpretations On 1 July 2022, the Group adopted an amendment to IAS 16/AASB 116 ‘Property, Plant and Equipment’ that requires an entity to recognise the sales proceeds from selling items produced while preparing property, plant and equipment for its intended use, and the related cost, in profit or loss, instead of deducting the amounts received from the cost of the asset. The amendment applies retrospectively to items of property, plant and equipment made available for use on or after 1 July 2020. However, no significant impacts have been identified in respect of the years ended 30 June 2021 and 30 June 2022 and, as such, comparative period financial information has not been restated.

Effective from 31 January 2022, the aggregate of the weighted average number of ordinary shares of only BHP Group Limited is considered in the computation of basic earnings per share. 3 For the purposes of calculating diluted earnings per share, the effect of 9 million dilutive shares has been taken into account for the half year ended 31 December 2022 (31 December 2021: 11 million shares; 30 June 2022: 10 million shares). The Group’s only potential dilutive ordinary shares are share awards granted under employee share ownership plans. Diluted earnings per share calculation excludes instruments which are considered antidilutive. At 31 December 2022, there are no instruments which are considered antidilutive (31 December 2021: nil; 30 June 2022: nil). 4 Each American Depositary Share (ADS) represents twice the earnings for BHP Group Limited ordinary shares. 5 Headline earnings is a Johannesburg Stock Exchange defined performance measure and is reconciled from earnings attributable to ordinary shareholders as follows: Half year ended 31 Dec 2022 US$M Half year ended 31 Dec 2021 US$M Year ended 30 June 2022 US$M Earnings attributable to BHP shareholders 6,457 9,443 30,900 Adjusted for: Loss/(gain) on sales of PP&E, Investments and Operations i 2 (110 ) (95 ) Impairments of property, plant and equipment, financial assets and intangibles 21 38 515 Gain on disposal of BHP Mitsui Coal – – (840 ) Gain on merger of Petroleum – – (8,167 ) Tax effect of above adjustments (1 ) 23 (97 ) Subtotal of adjustments 22 (49 ) (8,684 ) Headline earnings 6,479 9,394 22,216 Diluted headline earnings 6,479 9,394 22,216 i Included in other income.

Financial risk management – Fair values	8. Financial risk management – Fair values Recognition and measurement All financial assets and financial liabilities, other than derivatives and trade receivables, are initially recognised at the fair value of consideration paid or received, net of transaction costs as appropriate. Financial assets are initially recognised on their trade date. Financial assets are subsequently carried at fair value or amortised cost based on: - the Group’s purpose, or business model, for holding the financial asset; - whether the financial asset’s contractual terms give rise to cash flows that are solely payments of principal and interest. The resulting Financial Statements classifications of financial assets can be summarised as follows: Contractual cash flows Business model Category Solely principal and interest Hold in order to collect contractual cash flows Amortised cost Solely principal and interest Hold in order to collect contractual cash flows and sell Fair value through other comprehensive income Solely principal and interest Hold in order to sell Fair value through profit or loss Other Any of those mentioned above Fair value through profit or loss Solely principal and interest refers to the Group receiving returns only for the time value of money and the credit risk of the counterparty for financial assets held. The main exceptions for the Group are provisionally priced receivables and derivatives which are measured at fair value through the profit or loss under IFRS 9/AASB 9 ‘Financial Instruments’. The Group has the intention of collecting payment directly from its customers in most cases, however the Group also participates in receivables financing programs in respect of selected customers. Receivables in these portfolios which are classified as ‘hold in order to sell’, are provisionally priced receivables and are therefore held at fair value through profit or loss prior to sale to the financial institution. With the exception of derivative contracts and provisionally priced trade payables which are carried at fair value through profit or loss, the Group’s financial liabilities are classified as subsequently measured at amortised cost. The Group may in addition elect to designate certain financial assets or liabilities at fair value through profit or loss or to apply hedge accounting where they are not mandatorily held at fair value through profit or loss. Fair value measurement The carrying amount of financial assets and liabilities measured at fair value is principally calculated based on inputs other than quoted prices that are observable for these financial assets or liabilities, either directly (i.e. as unquoted prices) or indirectly (i.e. derived from prices). Where no price information is available from a quoted market source, alternative market mechanisms or recent comparable transactions, fair value is estimated based on the Group’s views on relevant future prices, net of valuation allowances to accommodate liquidity, modelling and other risks implicit in such estimates. The inputs used in fair value calculations are determined by the Group’s relevant subject matter experts, who operate under a defined set of accountabilities authorised by the Executive Leadership Team. Movements in the fair value of financial assets and liabilities may be recognised through the income statement or in other comprehensive income according to the designation of the underlying instrument. For financial assets and liabilities carried at fair value, the Group uses the following to categorise the inputs to the valuation method used based on the lowest level input that is significant to the fair value measurement as a whole: IFRS 13 Fair value hierarchy Level 1 Level 2 Level 3 Valuation inputs Based on quoted prices (unadjusted) in active markets for identical financial assets and liabilities. Based on inputs other than quoted prices included within Level 1 that are observable for the financial asset or liability, either directly (i.e. as unquoted prices) or indirectly (i.e. derived from prices). Based on inputs not observable in the market using appropriate valuation models, including discounted cash flow modelling. Financial assets and liabilities The financial assets and liabilities are presented by class in the table below at their carrying amounts.

A discounted cash flow approach is used to derive the fair value of cross currency and interest rate swaps at the reporting date. 3 Includes investments held by BHP Foundation which are restricted and not available for general use by the Group of US of which other investments (mainly US Treasury Notes) of US$135 million is categorised as Level 1 (30 June 2022: US$119 million). 4 Includes receivables contingent on outcome of future events relating to mining and regulatory approvals of . 5 Excludes input taxes of US$412 million (30 June 2022: US$427 million) included in other receivables. 6 Includes the discounted settlement liability in relation to the cancellation of power contracts at the Group’s Escondida operations. 7 Excludes input taxes of US$81 million (30 June 2022: US$79 million) included in other payables. 8 All interest bearing liabilities, excluding lease liabilities, are unsecured. The carrying amounts in the table above generally approximate to fair value. In the case of US$534 million (30 June 2022: US$3,018 million) of fixed rate debt not swapped to floating rate, the fair value at 31 December 2022 was US$548 million (30 June 2022: US$3,126 million). The fair value is determined using a method that can be categorised as Level 2 and uses inputs based on benchmark interest rates, alternative market mechanisms or recent comparable transactions. For financial instruments that are carried at fair value on a recurring basis, the Group determines whether transfers have occurred between levels in the fair value hierarchy by reassessing categorisation at the end of each reporting period. Interest Rate Benchmark Reform The London Interbank Offered Rate (LIBOR) and other benchmark interest rates are being replaced by alternative risk-free rates (ARR) as part of inter-bank offer rate (IBOR) reform. Sterling LIBOR ceased to be published on 1 January 2022 and USD LIBOR will no longer be published after 30 June 2023. Amendments to IFRS 9/AASB 9 ‘Financial Instruments’, IFRS 7/AASB 7 ‘Financial Instruments: Disclosures’ and IFRS 16/AASB 16 ‘Leases’ in relation to IBOR reform early adopted by the Group in previous periods impact the Group’s cross currency and interest rate swaps, which prior to IBOR reform referenced the US LIBOR benchmark, and the associated hedge accounting. These amendments provide relief from applying certain hedge accounting requirements to hedging arrangements directly impacted by IBOR reform. In particular, where changes to the Group’s instruments arise solely as a result of IBOR reform and do not change the economic substance of the Group’s arrangements, the Group is able to maintain its existing hedge relationships and accounting. During the half year ended 31 December 2022, the Group actively transitioned all impacted cross currency and interest rate swaps from US LIBOR to the alternative, widely adopted Secured Overnight Financing Rate (SOFR) benchmark. As the transition resulted solely from IBOR reform, the Group has applied the relief available in IFRS 9/AASB 9 ‘Financial Instruments’ and continues to apply hedge accounting to its hedging arrangements, including accounting for ineffectiveness. The Group does not hold any material lease arrangements that contain reference to existing benchmarks and as a result there is no material impact on lease liabilities or right-of-use

Key Programs include those for financial assistance and compensation of impacted persons, including fisherfolk impacted by the dam failure, and those for remediation of impacted areas and resettlement of impacted communities. A committee (the Interfederative Committee) comprising representatives from the Brazilian Federal and State Governments, local municipalities, environmental agencies, impacted communities and Public Defence Office oversees the activities of the Fundação Renova in order to monitor, guide and assess the progress of the actions agreed in the Framework Agreement. In addition, the To the extent that Samarco does not meet its Renova funding obligations during the 15 year term of the Framework Agreement, each of BHP Brasil and Vale have secondary funding obligations under the Framework Agreement in proportion to its 50 per cent shareholding in Samarco. Samarco began to gradually recommence operations in December 2020, however, there remains significant uncertainty regarding Samarco’s future cash flow generation and the outcome of the Judicial Reorganisation (outlined below). In light of these uncertainties and based on currently available information, BHP Brasil’s provision for its obligations under the Framework Agreement Programs is US$3.1 billion before tax and after discounting at 31 December 2022 (30 June 2022: US$3.2 billion). Under a Governance Agreement ratified on 8 August 2018, BHP Brasil, Samarco and Vale were to establish a process to renegotiate the Programs over two Pre-requisites re-negotiation BHP Brasil, Samarco, Vale and Federal and State prosecutors have been engaging in negotiations to seek a definitive and substantive settlement of the obligations under the Framework Agreement and the R$ billion (approximately US$ billion) Federal Public Prosecution Office claim. The negotiations are currently ongoing. Outcomes of the negotiations are highly uncertain and, until any revisions to the Programs are agreed, Fundação Renova will continue to implement the Programs in accordance with the terms of the Framework Agreement and the Governance Agreement. BHP Brasil, Samarco and Vale maintain security, as required by the Governance Agreement, with the security currently comprising insurance bonds and a charge over Samarco’s assets. Samarco Germano dam decommissioning Samarco is currently progressing plans for the accelerated decommissioning of its upstream tailings dams (the Germano dam complex). Given the uncertainties surrounding Samarco’s long-term cash flow generation, BHP Brasil’s provision for a 50 per cent share of the expected Germano decommissioning costs is US$164 million at 31 December 2022 (30 June 2022: US$184 million). While the decommissioning is progressing well, further engineering work may be necessary and required validation by Brazilian authorities could lead to changes to estimates in future reporting periods. Contingent liabilities The following matters are disclosed as contingent liabilities and given the status of proceedings it is not possible to provide a range of possible outcomes or a reliable estimate of potential future exposures for BHP, unless otherwise stated. Ultimately, all the legal matters disclosed as contingent liabilities could have a material adverse impact on BHP’s business, competitive position, cash flows, prospects, liquidity and shareholder returns. Federal Public Prosecution Office claim BHP Brasil is among the defendants named in a claim brought by the Federal Public Prosecution Office on 3 May 2016, seeking R$155 billion (approximately US$30 billion) for reparation, compensation and moral damages in relation to the Samarco dam failure. The BHP Brasil, Samarco, Vale and Federal and State prosecutors have been engaging in negotiations to seek a definitive and substantive settlement of the obligations under the Framework Agreemen t and the R$ billion (approximately US$ Australian class action complaints BHP Group Ltd is named as a defendant in a shareholder class action filed in the Federal Court of Australia on behalf of persons who acquired shares in BHP Group Ltd on the Australian Securities Exchange or shares in BHP Group Plc on the London Stock Exchange and Johannesburg Stock Exchange in periods prior to the Samarco dam failure. The amount of damages sought is unspecified. United Kingdom group action complaint BHP Group (UK) Ltd (former BHP Group Plc) and BHP Group Ltd were named as defendants in group action claims for damages filed in the courts of England. These claims were filed on behalf of certain individuals, governments, businesses and communities in Brazil allegedly impacted by the Samarco dam failure. The amount of damages sought in these claims is unspecified. In August 2019, the BHP parties filed a preliminary application to strike out or stay this action on jurisdictional and other procedural grounds. That application was successful before the High Court and the action was dismissed. However, on 8 July 2022, the Court of Appeal reversed the dismissal decision and allowed the action to proceed in England. The BHP defendants have sought permission to appeal to the Supreme Court of the United Kingdom and await a decision from the Supreme Court on their permission application. On 2 December 2022, the BHP defendants filed their defence and a contribution claim against Vale. The contribution claim contends that if BHP’s defence is not successful and they are ordered to pay damages to the claimants, Vale should contribute to any amount payable. Criminal charges The Federal Prosecutors’ Office has filed criminal charges against BHP Brasil, Samarco and Vale and certain employees and former employees of BHP Brasil (Affected Individuals) in the Federal Court of Ponte Nova, Minas Gerais. On 3 March 2017, BHP Brasil filed its preliminary defences. The Federal Court terminated the charges against eight of the Affected Individuals. The Federal Prosecutors’ Office has appealed seven of those decisions with hearings of the appeals still pending. BHP Brasil rejects outright the charges against the company and the Affected Individuals and is defending itself from all charges while fully supporting each of the Affected Individuals in their defence of the charges. Civil public action commenced by Associations concerning the use of Tanfloc for water treatment The Vila Lenira Residents Association, State of Espirito Santo Rural Producers and Artisans Association, Colatina Velha Neighbourhood Residents Association, and United for the Progress of Palmeiras Neighbourhood Association have filed a lawsuit against Samarco, BHP Brasil and Vale and others, including the State of Minas Gerais, the State of Espirito Santo and the Federal Government. The plaintiffs allege that the defendants carried out a clandestine study on the citizens of the locations affected by the Fundão’s Dam Failure, using TANFLOC – a tannin-based flocculant/coagulant – that is currently used for wastewater treatment applications. The plaintiffs claim that this product allegedly put the population at risk due to its alleged experimental qualities. The plaintiffs are seeking multiple kinds of relief – material damages, moral damages, loss of profits – and that the defendants should pay for water supply in all locations where there is no water source other than the Doce River. On 25 July 2022, Samarco, BHP Brasil and Vale presented their defences individually, as well as the State of Minas Gerais, the State of Espirito Santo and the Federal Government. The Court’s decision is still pending. Other claims BHP Brasil is among the companies named as defendants in a number of legal proceedings initiated by individuals, non-governmental Additional lawsuits and government investigations relating to the Samarco dam failure could be brought against BHP Brasil and possibly other BHP entities in Brazil or other jurisdictions. BHP insurance BHP has various third party general liability and directors and officers insurances for claims related to the Samarco dam failure made directly against BHP Brasil or other BHP entities, their directors and officers, including class actions. External insurers have been notified of the Samarco dam failure along with the third party claims and class actions referred to above. Recoveries related to general liability insurance are now considered complete. As at 31 December 2022, an insurance receivable has not been recognised for any potential recoveries in respect of ongoing matters. Commitments Under the terms of the Samarco joint venture agreement, BHP Brasil does not have an existing obligation to fund Samarco. BHP has agreed to fund a total of up to US$915 million for the Fundação Renova programs during calendar year 2023. Any additional requests for funding or future investment provided would be subject to a future decision by BHP, accounted for at that time. To the extent that Samarco does not meet its Fundação funding obligations, each of BHP Brasil and Vale has funding obligations under the Framework Agreement in proportion to its 50 per cent shareholding in Samarco. Samarco judicial reorganisation Samarco filed for Judicial Reorganisation (JR) in April 2021, with the Commercial Courts of Belo Horizonte, State of Minas Gerais, Brazil (JR Court), after multiple enforcement actions taken by certain financial creditors of Samarco which threatened Samarco’s operations. The JR is an insolvency proceeding with a means for Samarco to seek to restructure its financial debts and establish a sustainable financial position that allows Samarco to continue to rebuild its operations and strengthen its ability to meet its Fundação Renova related funding obligations. Samarco’s operations have continued during the JR proceeding. According to the list of creditors filed with the JR Court by the Judicial Administrators (who are in charge of a first review of the list of creditors filed by Samarco), Fundação Renova’s funding obligations undertaken by Samarco are not subject to the JR, although some financial creditors of Samarco have objected to this position. Some of such creditors filed challenges to the list of creditors filed by the Judicial Administrators, in order to, among other things, prevent Samarco from funding Fundação Renova. In December 2021, the Federal Court granted BHP Brasil’s request that Samarco be able to fund Fundação Renova obligations, overturning a temporary injunction against such funding previously granted by the State Court of Appeals of Minas Gerais (State Court) in October 2021. BHP Brasil also obtained a preliminary injunction from the Superior Court of Justice supporting the jurisdiction of the Federal Court, and not the State Court, in this specific matter. An appeal on the merits against this ruling by certain financial creditors is still to be ruled upon. Samarco has, with the support of BHP Brasil and Vale, continued to meet its Fundação Renova funding obligations. In April 2022, Samarco presented a restructure proposal for voting at a meeting of its creditors (GMC) under the JR proceeding, which was rejected by certain of the Samarco financial creditors. Samarco, BHP Brasil and Vale subsequently each filed objections with the JR Court against the voting process regarding the rejection of the Samarco proposal. The Samarco financial creditors and Samarco’s employee unions then proposed alternative restructure proposals, which remain subject to ongoing consideration, including a legality check from the Judicial Administrators and the JR Court. In August 2022, Samarco, BHP Brasil, Vale and certain financial creditors took part in a court sanctioned mediation process, however an agreement was unable to be reached. In October 2022, the JR Court issued a ruling that extended the so-called stay period until April 2023, which provides Samarco with protection from enforcement actions by its creditors. In November 2022, the JR Court issued rulings regarding various legal matters in the JR process. One ruling rejected the claims by certain financial creditors and the State Prosecutors of Minas Gerais (MPMG) that the corporate veil of Samarco should be pierced and that BHP Brasil and Vale should be held liable for the debts of Samarco that are subject to the JR. The MPMG has appealed this JR Court ruling. The JR Court also held that BHP Brasil and Vale are unable to vote their claims at a GMC and that employees unions and certain financial creditors are also unable to vote their claims at a GMC in relation to the respective restructure plans that they each proposed. Certain financial creditors have appealed this JR Court ruling. In addition, the JR Court dismissed certain It is expected that there will be continuing litigation from financial creditors against Samarco and its shareholders over the course of the JR proceeding, including with respect to the treatment of Samarco’s Fundação Renova-related obligations and continued attempts to pierce Samarco’s corporate veil to hold BHP Brasil and Vale liable for Samarco’s debts. The duration and outcome of the JR remains uncertain with the potential for protracted litigation and appeals because, among other things, the Samarco JR is occurring under new and untested Brazilian bankruptcy legislation. While the JR is not expected to affect Samarco’s obligation or commitment to make full redress for the 2015 Fundão dam failure, and is not expected to impact Fundação Renova’s ability to undertake that remediation and compensation, it is not possible to determine the outcomes of the JR or reliably estimate any impact that the reorganisation may have for BHP Brasil, including its share of the Samarco dam failure provisions. Key judgements and estimates Judgements The outcomes of litigation are inherently difficult to predict and significant judgement has been applied in assessing the likely outcome of legal claims and determining which legal claims require recognition of a provision or disclosure of a contingent liability. The facts and circumstances relating to these cases are regularly evaluated in determining whether a provision for any specific claim is required. Management has determined that a provision can only be recognised for obligations under the Framework Agreement and Samarco Germano dam decommissioning as at 31 December 2022. It is not yet possible to provide a range of possible outcomes or a reliable estimate of potential future exposures to BHP in connection to the contingent liabilities noted above, given their status. Estimates The provision for the Samarco dam failure currently only reflects the Group’s estimate of the remaining costs to complete Programs under the Framework Agreement and requires the use of significant judgements, estimates and assumptions. Based on current estimates, it is expected that approximately per cent of remaining costs for Programs under the Framework Agreement will be incurred by December . While the provisions have been measured based on the latest information available as at 31 December 2022, changes in facts and circumstances are likely in future reporting periods and may lead to revisions to these estimates. However, it is currently not possible to determine what facts and circumstances may change, therefore revisions in future reporting periods due to the key estimates and factors outlined below cannot be reliably measured. The key estimates that may have a material impact upon the provisions in the next and future reporting periods include the: • number of people eligible for financial assistance and compensation and the corresponding amount of expected compensation; and • costs to complete key infrastructure programs. The provision may also be affected by factors including but not limited to: • potential changes in scope of work and funding amounts required under the Framework Agreement including the impact of the decisions of the Interfederative Committee along with further technical analysis, community participation required under the Governance Agreement and rulings made by the • the outcome of ongoing negotiations with State and Federal Prosecutors, including review of Fundação Renova’s Programs as provided in the Governance Agreement; • actual costs incurred; • resolution of uncertainty in respect of the nature and extent of Samarco’s long term cash generation; • updates to discount and foreign exchange rates; and • the outcomes of Samarco’s judicial reorganisation. In addition, the provision may be impacted by decisions in, or resolution of, existing and potential legal claims in Brazil and other jurisdictions, including the outcome of the United Kingdom group action complaint and the negotiations seeking a definitive and substantive settlement of the obligations under the Framework Agreement and the R$155 billion (approximately US$30 billion) Federal Public Prosecution Office claim. Outcomes of the negotiations are highly uncertain and it is therefore not possible to provide a reliable estimate of potential outcomes. Given these factors, future actual cash outflows may differ from the amounts currently provided and changes to any of the key assumptions and estimates outlined above could result in a material impact to the provision in the next and future reporting periods.

Outcomes of the negotiations are highly uncertain and it is therefore not possible to provide a reliable estimate of potential outcomes. Given these factors, future actual cash outflows may differ from the amounts currently provided and changes to any of the key assumptions and estimates outlined above could result in a material impact to the provision in the next and future reporting periods.

Effective from 31 January 2022, the aggregate of the weighted average number of ordinary shares of only BHP Group Limited is considered in the computation of basic earnings per share. 3 For the purposes of calculating diluted earnings per share, the effect of 9 million dilutive shares has been taken into account for the half year ended 31 December 2022 (31 December 2021: 11 million shares; 30 June 2022: 10 million shares). The Group’s only potential dilutive ordinary shares are share awards granted under employee share ownership plans. Diluted earnings per share calculation excludes instruments which are considered antidilutive. At 31 December 2022, there are no instruments which are considered antidilutive (31 December 2021: nil; 30 June 2022: nil). 4 Each American Depositary Share (ADS) represents twice the earnings for BHP Group Limited ordinary shares. 5 Headline earnings is a Johannesburg Stock Exchange defined performance measure and is reconciled from earnings attributable to ordinary shareholders as follows:
