Hello, thank you for joining us to hear about BHP's results for the December 2022 half-year. I'm joined by our Chief Financial Officer, David Lamont. I want to start by acknowledging the tragic loss of life of one of our team members, Jody Byrne, in our rail operations at Port Hedland the week before last. My deepest sympathies go out to his family and friends, as well as his colleagues. We're supporting them in any way we can at this difficult time. We've commenced our investigation, the findings of which will be implemented thoroughly. Safety is our number one priority. Nothing matters more. We have been intensely focused on eliminating fatalities from BHP, but as this terrible incident so tragically reminds us, safety requires constant vigilance, and we are redoubling our efforts. We will not rest in our efforts to ensure no one gets harmed while at work at BHP. We continued to execute our strategy during the half and maintained operational rigor in the face of challenging external circumstances. We've again delivered steady and reliable operating performance, supporting our ability to consistently deliver attractive shareholder returns and to increase our investment in growth. We're also continuing to optimize our portfolio. We've added to and accelerated our exposure to future-facing commodities, the minerals critical to the energy transition, including through our offer for OZ Minerals. With our joint venture partner, we've started to pursue options to divest the Daunia and Blackwater mines. This will further concentrate our coal portfolio on only the highest quality metallurgical coals for steelmaking. These higher quality coals support more efficient blast furnace operations and lower relative emissions intensity. I'll ask David to speak about the financials in detail shortly, but first I'd like to share some highlights from the last six months. Our teams have delivered steady and reliable operational performance. We achieved record half-year production at Western Australian Iron Ore, supported by strong performance right across the supply chain. Copper production rose as Escondida accessed higher-grade ore, the Spence concentrator continued to ramp up, and Olympic Dam extended its recent track record of operational stability. BMA, while impacted by recent wet weather, demonstrated improvements in underlying productivity. Our continued focus on operational excellence and cost control has helped us to contain the impacts of inflation on our cost base, but we're far from complacent and are keeping a close eye on costs. Despite severe weather in Eastern Australia, commodity price and inflationary headwinds, and labor availability challenges, our continued resilient performance has delivered earnings of more than $13 billion and enabled us to announce a dividend of $0.90 per share for the half year. That's $4.6 billion that flows back to all of our investors. We've also continued to generate social value for and with those around us, governments, our workforce, our suppliers, our customers, and the communities where we operate. The creation of social value is essential to better business outcomes and long-term shareholder value because it supports stable operations and reduces risk to the business. It also opens the door to future opportunities, partnerships, capital, and talent. The value we create includes the taxes and royalties we've paid. This half, we paid $7.5 billion in taxes and royalties, which support government budgets and pay for essential infrastructure and services. In fact, last year in Australia, BHP paid close to 10% of all the nation's corporate tax, a figure that reflects the importance of our success to the national economy. We also made substantial contributions via wages, community contributions, and local procurement, contributions that are supporting lives, livelihoods, and regional development. Everything that BHP earns ultimately gets distributed to governments, to local businesses and suppliers, to employees, and to our shareholders, including around 70% of all Australians who benefit through their direct BHP shareholdings or superannuation funds. On operational greenhouse gas emissions, we're on track to meet our target of at least a 30% reduction by the 2030 financial year, including through our recent signings of power purchase agreements for renewable electricity at Olympic Dam and Port Hedland. We continue to focus on reducing our use of freshwater through innovation and investment in desalination. We've increased female representation across the group to more than 33%, a near doubling since we announced our aspirational goal to achieve a gender-balanced workforce back in 2016. Pleasingly, we also released our updated Indigenous Peoples Policy Statement during the half. This statement strengthens our commitment to working with indigenous peoples to support reconciliation and contribute to better social, economic, and environmental outcomes. Over the last six months, we've more than doubled our spend with Indigenous suppliers from the previous December half, including through an agreement with a Banjima owned and operated business to operate and maintain one of our semi-mobile crushers in the Pilbara. This agreement not only provides employment opportunities but helps build long-term business capacity. These efforts align with our social value framework, which we announced in June last year. We're using the framework to hardwire social value into every level of decision-making across our global operations. David will now take you through the financial results from the half year. Thanks, Mike. We have delivered another strong set of results despite a more challenging backdrop with lower prices and other external pressures. Underlying attributable profit was $6.6 billion or $1.30 per share, one of our top half year results. This incorporates an effective tax rate, including royalties, of 40%. Underlying EBITDA remained very healthy at $13.2 billion, and our margin at 54% and return on capital employed at 29% remained strong, reflecting the quality and resilience of our assets and consistent operating performance. Over the half, we spent $3 billion on capital and exploration expenditure. Our full year guidance remains unchanged at $7.6 billion. As always, we remain disciplined and guided by our Capital Allocation Framework. Our shareholders continue to benefit from our consistent and reliable performance. As Mike mentioned, our interim dividend is $0.90 per share, fully franked, which is the fifth highest ordinary dividend ever. Digging into the details, the EBITDA waterfall highlights the significant impact of lower commodity prices, by far the biggest driver of the period on period decline in earnings. Iron ore and copper, our two largest segments, saw prices down 25% and 19% respectively from the December 2021 half. As expected, we continue to see the lag effect of inflation. This had a - $1 billion impact this half, which equates to around an effective rate of 12%. The most significant impact was in diesel, although we do see some relief in the second half as prices have recently come off their peak. The favorable impact of the weaker Australian dollar and Chilean peso against the U.S. dollar were only a partial offset to inflation. Beyond these external pressures, I am pleased that we have delivered well against the areas within our control. Due to strong performance at our iron ore and copper assets, higher volumes delivered an increase of $700 million. We managed controllable costs well, with inventory movements accounting for the majority of the $500 million increase. These inventory movements were mainly driven by the planned drawdown of stocks at Olympic Dam as we processed stocks built during the prior period ahead of the major smelter maintenance campaign. Inventory also reduced at Western Australian Iron Ore, Nickel West, and BMA, largely as a consequence of wet weather and labor availability challenges. The $400 million sitting in the other category largely reflects lower recovery of freight costs caused by movements in the freight index and the lower profit at Antamina, mainly due to lower copper price. Over the past five years, we have consistently delivered EBITDA margins above 50%, with iron ore above 60% and copper above 45%. Underpinned by record production, Western Australia Iron Ore delivered an EBITDA of $7.6 billion at a 65% margin. We delivered strong performance across the supply chain, and the ongoing ramp up at South Flank is increasing the average quality of our product. With C1 costs of $15.50 per tonne, up only 5%, we have extended our lead as the lowest cost major producer. In copper, our EBITDA margin remains very healthy at 44%. Escondida's production increased by 5% with concentrator feed grade up 7 percentage points from the prior December half. While unit costs increase, reflecting the inflationary environment, these increases are below what others in the industry are experiencing. Our other copper assets also performed well. Olympic Dam's ongoing strong performance saw near record materials process and record gold production, while the Spence concentrator continued to ramp up. At BMA, coal production was up 5%. Despite significantly more rain, higher productivity on dry days allowed us to do almost the same amount of stripping as last year. The increase in unit costs largely reflects inflationary pressures and significant drawdown on mine inventories, partly in order to capture the higher price environment in the period rather than the traditional build in the half. In nickel, our EBITDA margin was lower, largely due to unfavorable inventory movements, inflationary pressures, and the downtime at the refinery following planned maintenance. At New South Wales Energy Coal, while benefiting from record prices, conditions remained very challenging. Volumes were down significantly due to the wettest half in six decades. This, plus inflation, contributed to sharply higher unit costs to just over $100 or around AUD 150 per tonne in the half. At Jansen, stage one is now 16% complete and is progressing on time and on budget. We now expect capital expenditure this financial year of around $860 million, up $120 million, largely due to the accelerated production schedule. Stepping back, we continue to perform well, both operationally and on the cost front. As expected, we are seeing the impact of inflation across our global supply chains, as well as labor availability challenges, particularly in the Australian operation. That said, our ongoing focus on productivity and controllable costs, we are managing these external headwinds extremely well. Thank you. I'll now hand back over to Mike. Thank you, David. I'd like now to take you through how we see the outlook for the commodities we produce and what we're doing to position and grow our portfolio. Over the course of this calendar year, we expect three key themes to play out. We expect to see a slowing of growth in Europe and the U.S. as the lagged impacts of last year's anti-inflation policies and the energy crisis continue to flow through. Conversely, China's reopening is progressing well, with positive social and economic signposts emerging. Bank lending, mobility data, new home prices, and business surveys are all showing solid signs of improvement in early calendar 2023. The pent-up demand being released as China opens back up from the COVID lockdowns, coupled with growth-promoting policies such as the support for the housing market, are expected to drive stronger economic growth and increase demand for the commodities we produce. We said in August that we believe that China will be a stabilizing force for global growth over the remainder of this year, and we now have even greater conviction in this view. Finally, while it varies by region, an easing of global inflation may allow central banks to end their rate tightening cycles in the coming quarters. As such, we expect world growth will strengthen in 2024. As always, there are many moving parts in the near term. However, it's fair to say that the economic picture is clearer now than it was six-12 months ago. We remain very confident in the long-term demand for commodities driven by the global trends playing out around us. The fundamentals that underpin our strategy are unchanged, supplying metals and minerals the world will need for a growing population, increasing standards of living, and the energy transition. We have world-class assets and commodities we confidently expect to be in strong demand for decades to come. By 2050, the world is projected to be home to around 10 billion people. That's 2 billion more than today. Those 10 billion people will need more efficient food production from less arable land, supporting demand for potash for fertilizer. On current estimates, more than 2 billion of them will drive electric cars. That's about 100 x current figures, so that means more copper and nickel. 7 billion will likely live in urban areas, 2.5 billion more than today, which means steel for construction and infrastructure. That takes iron ore and higher quality metallurgical coal. To power it all with lower carbon emissions, an enormous increase in global energy production from wind and solar will be needed, meaning more copper, more steel. I've talked before about the magnitude of the increase in key commodities, copper, nickel, and steel, that both traditional demand drivers and decarbonization will require. We believe the long-term demand outlook is clear and enduring. There will be significant challenges in meeting it. The lack of new discoveries of attractive large-scale deposits, land and water scarcity, changing societal expectations, and difficulty in securing permits to operate or expand in some jurisdictions. Our portfolio is built to compete in this complex but opportunity-rich environment. We have the largest copper endowment and the second-largest nickel sulfide resource globally. We are a leading producer of both iron ore and higher quality metallurgical coal for steelmaking, and we have plans to be a globally significant potash supplier. As demand for these essential commodities rises, BHP, as an incumbent large-scale producer and with the size and quality of our assets, balance sheet, and proven operational excellence, has an embedded advantage. We're ready to do our part to supply the world with the commodities it needs. In turn, we are seeing a growing understanding of these needs globally. Indeed, over the past two years, there's been a growing awareness of the essential nature of these minerals to the energy transition. With that, we've seen an increase in policies that will support responsible and sustainable mining to meet the growth and demand. Governments around the world are seeking to work with business to speed up approvals processes and ensure attractive investment settings. We're a global company with numerous options to deploy our capital. Every project has to compete against other proposals from all of our global assets on a range of metrics: resource quality, technical risk, commodity outlook, capital expenditure, expected returns, as well as the fiscal competitiveness and stability and sovereign risk of the regions in which we are looking to invest. We continue to allocate our capital accordingly. I'd like to mention two projects in regions where we are investing for growth, Western Australia Iron Ore and the Jansen potash project in Canada. WAIO is an incredible asset. Over many years, we've been removing bottlenecks so we can get more of our iron ore onto more ships at Port Hedland and do it safely, reliably, and cost-effectively. We have plans in place to grow production to more than 300 million tons per year in the medium term. This is low capital intensity, highly efficient growth. We're studying options to grow beyond this to 330 million tons per annum. As always, we prioritize the pursuit of valuable growth. At Jansen, the $5.7 billion stage one project is running to plan. We've awarded $2.5 billion in contracts. Engineering is now over 80% complete, and 85% of procurement orders have been placed, giving us confidence in our plans and schedule. We now expect first production in late calendar year 2026, as progress to date has enabled us to accelerate procurement contracts and bring forward mobilization of key contractors to site. We've also poured first concrete ahead of schedule and advanced the foundations for our Stage 1 mill, thanks to an extended summer season last year. We've also accelerated Jansen Stage 2 studies. We now expect to complete the feasibility study in the 2024 financial year, a year earlier than we've said previously, giving us additional optionality on when we bring these tons to market. We're always looking at how we can grow further value from our assets, and we've got a number of organic options across our portfolio, including in future-facing commodities. That's important because we're aiming to have half of our portfolio made up of future-facing commodities by 2030. In the near term, we're accelerating studies across our copper assets. At Escondida and Pampa Norte in Chile, we're looking at options to add to production, including through both our concentrator strategy and leaching technologies, which would help us extract more copper, either through reprocessing ore or unlocking ore that can't be recovered using conventional methods. In South Australia, we are studying the optimal growth pathway for Olympic Dam, including a two-stage smelter, which would deconstrain mining operations. Oak Dam is feeding into this thinking as well. After a further 40 km of drilling since May 2021, we have been able to better define the extent of the mineralization, and we continue to see encouraging results. Of course, the OZ Minerals assets would provide access to additional production and growth options. While organic growth will always be a clear focus, we have additional growth levers at our disposal. Exploration, which is about finding new deposits, early-stage entry, where we get in on the ground floor with smaller miners and bring our skills and scale to bear on a project to help it grow, as well as technology and innovation, which we use to get better and more efficient at what we do and to unlock more of our incredible resources. We're taking active steps to create and accelerate long-term options. I'll highlight three of those today where we are taking innovative approaches: exploration, BHP Ventures, and BHP Xplor. While in the context of BHP, these are relatively small investments, they are highly strategic, and in time, we hope that they will become meaningful contributors. Firstly, exploration. We're increasing exploration efforts, building our team, and increasing our spend. This is a significant focus area for us. We're seeking new targets in mature terrains through applying new technologies, prioritizing greenfield exploration for both copper and nickel, and we're actively growing and expanding into new jurisdictions, as we've shown with our recent agreement with Mundoro, covering three exploration projects in Serbia. Secondly, BHP Ventures, our own venture capital arm, where we've screened more than 1,200 opportunities and built a high-quality global portfolio of over 20 holdings in just three years, five of those in the last half. Ventures is focused on emerging technologies that can help grow and improve our existing operations, our resource base, and our value chain. This includes via new subsurface exploration techniques using artificial intelligence through KoBold Metals. We're supporting the potential to reduce Scope 3 emissions from steelmaking through electrolysis companies like Boston Metal and Electra. Third, through BHP Xplor, which merges concepts from venture capital and early-stage accelerators. We announced Xplor in August 2022 and had hundreds of applications from all around the world focused on exploration and discovery of copper, nickel, and other critical minerals. We've now selected seven companies, and we'll provide funding and support to accelerate their growth and potentially to partner with them. Our approach is innovative, fast-paced, and disruptive. We have to be. The industry must be willing to take more risks in deploying innovative technologies to supply the needs of the energy transition. Before I conclude, I'll touch just briefly on progress on our proposed acquisition of OZ Minerals. We only pursue acquisitions where we believe we can create value for our shareholders. We believe the proposal we put to OZ Minerals represents highly compelling value for shareholders on both sides. The OZ Minerals board has recommended it unanimously. OZ Minerals will increase our exposure to copper, uranium, and nickel, all of which are important for the energy transition. It has a compelling growth pipeline, and there are attractive potential synergies, including through the proximity to our existing assets. This is a good company run by good management, and they've unlocked substantial value so far. We intend to retain the vast majority of OZ Minerals' workforce and bring together the best from both companies in terms of culture and approach. While their recent results demonstrate that OZ is under the same inflationary pressures as everyone else, this is no surprise, and we believe BHP can, over time, unlock even greater value. OZ Minerals expects to distribute more information to its shareholders in a scheme booklet in early March, to hold their scheme meeting for their shareholders to vote on the scheme in April, with implementation in either late April or early May. We think the OZ Minerals assets are a good fit for BHP, and we look forward to reporting further on the transaction as it progresses. In summary, BHP continues to deliver the strong and consistent performance and attractive returns that our stakeholders have come to expect, and the future couldn't be more exciting. Our strategy is simple. We have built a portfolio of world-class assets, low cost with options to expand, and we operate them very well. We are disciplined on cost and capital, and we have a long-standing commitment to social value. As the global population grows, as urbanization increases, and as the world pursues a low emissions energy transition, our portfolio is set up for success. Copper, nickel, potash, iron ore, and higher quality metallurgical coal for steelmaking, all vital to the future. While what we produce is essential, how we manage our business has never been more important, more sustainably, and in a way that creates enduring mutual benefit for those that support and rely on us, our people, partners, the economy, the environment, Indigenous partners, local communities, and shareholders. To do this, we remain focused on operational excellence, cost and capital discipline, and delivering value and returns. BHP remains strongly positioned to create value now and into the future. Thank you.
