OZ MINERALS BOARD INTENDS TO RECOMMEND BHP'S REVISED PROPOSAL

BHP has submitted a revised non-binding indicative proposal to the Board of OZ Minerals Limited (OZL) to acquire 100% of OZL by way of a scheme of arrangement for a cash price of A$28.25 per OZL share (the Revised Proposal). This offer price represents the best and final price BHP is willing to offer under the Revised Proposal, in the absence of a competing proposal.

The OZL Board has confirmed to BHP that it intends to unanimously recommend the Revised Proposal to OZL shareholders as being in the best interests of OZL shareholders in the absence of a superior proposal subject to the parties entering into a binding scheme implementation agreement (SIA) following completion of BHP's confirmatory due diligence and an independent expert concluding that the Revised Proposal is in the best interests of OZL shareholders.

The Revised Proposal price of A$28.25 per share corresponds to an enterprise value of A$9.6 billion¹ for OZL and represents a significant and attractive premium of:

•     49.3% to OZL's closing price of A$18.92 per share on 5 August 2022, being the last trading day prior to the initial proposal by BHP;

•     59.8% to OZL's 30-day VWAP of A$17.67 per share up to and including 5 August; and

•     a 13.0% increase to BHP's original offer price of A$25.00 per share.

OZL may pay a franked dividend to OZL shareholders prior to the transaction being implemented. The cash consideration price under the Revised Proposal will be reduced by the cash component of any dividends or return of capital paid by OZL before the date of the implementation of the Revised Proposal.

BHP has entered into a Confidentiality and Exclusivity Deed with OZL in relation to the Revised Proposal. Under the Confidentiality and Exclusivity Deed, OZL has granted BHP 4 weeks to undertake exclusive confirmatory due diligence and negotiate a binding SIA reflecting the key terms of the Revised Proposal. The 4 week period is expected to commence on or around Monday 21 November 2022.

BHP Chair, Ken MacKenzie said:

"BHP's proposal would provide value to BHP shareholders by increasing exposure to future facing commodities, attractive synergies and adding to our pipeline of growth options."

BHP CEO Mike Henry said:

"BHP's proposal represents a highly compelling offer for OZL shareholders, providing certainty at a time of macroeconomic uncertainty and market volatility, and increasing risks for the industry.

"The combination of BHP and OZL's assets, skills and technical expertise provides a unique opportunity not available under separate ownership, with complementary resources including the Oak Dam exploration prospect and existing facilities within close proximity, backed by BHP's strong balance sheet, capital discipline and commitment to sustainable development."

Attractive Strategic Rationale

The proposed transaction is expected to deliver significant value creation for both BHP and OZL shareholders.

Benefits to OZL shareholders and other stakeholders include:

• Significant and attractive premium: OZL shareholders would receive an offer price significantly above trading levels and average broker price targets, prior to BHP's initial proposal on 5 August 2022;
• Value: the Revised Proposal delivers full and fair value at a level that rewards OZL shareholders for the attractive long term market fundamentals for copper and nickel, OZL's growth pipeline and the unique synergy value available to BHP;
• Cash certainty: the Revised Proposal provides cash certainty at a time of increased market volatility in the global base metals industry; and
• Workforce: BHP expects to retain the vast majority of the OZL team who would become part of a much larger organisation with access to industry-leading employee benefits including training programs, flexible work options and career progression opportunities both domestically and internationally across a suite of commodities.

Benefits to BHP shareholders include:

• Increased exposure to future facing commodities: The acquisition would add copper and nickel resources that are essential to support the global megatrends of decarbonisation and electrification. This is consistent with BHP's strategy to deliver long term value and returns through owning a portfolio of world class assets with exposure to highly attractive commodities that benefit from global mega-trends.
• Attractive synergies: Creation of a South Australian copper basin which could unlock potential operational synergies due to the proximity of OZL's Carrapateena and Prominent Hill operations with BHP's existing Olympic Dam asset and Oak Dam development resource.
• Growth options: OZL brings attractive brownfield copper expansion projects at Prominent Hill and Carrapateena in South Australia. The West Musgrave project will add a large greenfield nickel option to BHP's Nickel West premier nickel sulphide resource position in Western Australia.

Conditions to the Revised Proposal

The Revised Proposal is subject to certain conditions including completion of due diligence to the satisfaction of BHP, entry into an SIA, and a unanimous recommendation from the OZL Board that shareholders vote in favour of the Revised Proposal in the absence of a superior proposal and an independent expert concluding that the Revised Proposal is in the best interests of OZL shareholders. If the conditions are satisfied and the Revised Proposal proceeds, completion of the transaction will also be subject to conditions expected to include receipt of approvals from regulators in relevant jurisdictions, OZL shareholder approval, Australian court approval of the scheme of arrangement, no material adverse change in relation to OZL, no prescribed occurrences and other conditions customary for a transaction of this nature.

There is no guarantee that any transaction will eventuate or proceed at this stage. BHP will continue to focus on its pipeline of organic development opportunities and demonstrate a capital disciplined approach in relation to acquisition opportunities.

BHP will continue to update the market on the Revised Proposal in accordance with its continuous disclosure obligations.
