William Oplinger, CEO

Today is an exciting day for Alcoa. We are announcing a transaction that is a defining moment for Alcoa and our shareholders as it strengthens our leadership as a pure play upstream aluminum company. We have entered into a definitive agreement to acquire South32's interests in a portfolio of high-quality bauxite, alumina, and aluminum assets in Australia, Brazil, and South Africa for upfront consideration of $4.1 billion. I'll start by taking you through an overview of the transaction and its strategic and financial benefits. Molly and I will take questions at the end of the discussion. This is exactly the type of opportunity we've been preparing for. one that strengthens our portfolio, enhances our competitiveness, and creates long-term value for shareholders by unlocking synergies that are not available otherwise. The transaction includes South32's interest in the Boddington Bauxite Mine, Worsley Aluminum Refinery, Hillside Aluminum Smelter, the Alumar Refinery and Smelter, and MRN Bauxite Mine. Together, these are world-class operations that complement our existing footprint and enhance our ability to generate value through the cycle. They have strong operating histories, attractive cost positions, and limited integration risk. This transaction does not include the Moselle smelter in Mozambique, which was previously placed under care and maintenance by South32. The consideration consists of $3.1 billion of cash and 17 million newly issued Alcoa shares, or approximately 6% of Valcoa's outstanding shares post issuance. This represents total equity value of $4.1 billion. Including assumed lease-related liabilities, the implied enterprise value is approximately $4.7 billion. The transaction also includes a contingent value right of up to $750 million tied to future market conditions. We agreed to structure the transaction on a lockbox basis to ensure price certainty, avoid post-close adjustments, and enable a clean transition. While more frequently used in transactions outside the U.S., the lockbox structure allows Alcoa to benefit from the acquired asset's cash generation from March 31, 2026. We will have the risk of market price movements, but we will also have the benefit of a streamlined path to integration and combined value realization. We expect this transaction to generate approximately $900 million of net present value synergies, supported by portfolio optimization, procurement savings, and our proven operating capabilities. We also expect the transaction to be immediately accretive to earnings per share and free cash flow after closing. Turning to financing, we are taking a disciplined approach that is consistent with how we've managed the balance sheet over the last several years. We have secured bridge financing commitments, but fully expect to replace that bridge with a combination of balance sheet cash and permanent debt financing before closing. Regarding the equity component, upon closing, SOW32 will distribute at least half of the Alcoa shares provided as consideration to its shareholders via an in-specie distribution. SOW32 is able to sell the remaining shares in an orderly manner without a lockup period. Maintaining a strong balance sheet remains a priority, and we will continue to apply the same capital allocation discipline that investors have come to expect from Alcoa. Finally, on timing, the parties have signed transaction documentation, and there are no financing conditions remaining. We will pursue required various regulatory approvals, including in Australia, Brazil, the European Union, South Africa, and the United States. The transaction is subject to South32's shareholders' approval, which is expected later this year. The approvals process is anticipated to take up to 12 months from today's announcement, enabling the transaction to close during the first half of 2027. Stepping back, the transaction brings together three elements that matter most to create shareholder value. Strategic fit, actionable synergies, and stronger financial performance. First, we're bringing together highly complementary assets that are mostly in close geographic proximity to our existing portfolio. That combination creates opportunities to improve performance, enhance our cost competitiveness, and strengthen the resilience of our supply chain. It also enables us to better serve customers by leveraging a larger and more integrated operating footprint. Second, this transaction unlocks significant value through synergies. We have so far identified approximately $900 million of net present value synergies, including roughly $50 million of run rate cost savings that we expect to realize within the first year following closing. These synergies are driven by real industrial logic with opportunities to leverage the collective strength of the Australian operations, improve the Brazilian assets through sourcing optimization, and add the benefits of a large-scale, stable smelter in South Africa with proven operating performance. Importantly, these synergies are highly actionable and are based on areas where Alcoa has a demonstrated track record of execution. Third, the transaction delivers compelling financial results. We expect the acquisition to be accretive to our earnings per share and cash flow metrics immediately after close, with additional upside as synergies are captured over time. These assets enhance our ability to generate stronger cash flow through the cycle and further improve our position on the global alumina and aluminum cost curves. As we've consistently said, our strategy is not simply to get bigger. It is to build a stronger, more competitive Alcoa. This transaction advances that objective by increasing our exposure to high-quality, low-cost assets, improving the quality of our earnings and cash flow, and strengthening our ability to perform through the cycle. When you bring together the strategic fit, the actionable synergy opportunity, and the compelling financial benefits, The conclusion is clear. This acquisition strengthens Alcoa's position as the leading pure play upstream aluminum company, enhances our ability to capture long-term demand growth, and reinforces Alcoa's position as the aluminum investment of choice for investors seeking exposure to a high-quality, globally competitive upstream aluminum portfolio. Turning to the portfolio fit, we're acquiring high-quality assets in regions where we already have deep operating expertise, established relationships, proven track record of execution, as well as expanding our footprint in Africa. In Australia, the Boddington Mine and Worsley Refinery sit alongside our existing mining and refining system, creating opportunities to further strengthen one of the world's premier Illumina regions. in brazil we're increasing our ownership and assets we already know well which gives us a clear path to operational and commercial optimization and in south africa hillside complements our existing smelting portfolio and expands our participation in the aluminum value chain by integrating world-class operations and talent with our operating model technical and commercial capabilities we see meaningful opportunities to leverage our combined expertise to improve performance and sustainably lower our cost base. These competitive assets will strengthen Alcoa's portfolio. Starting with Worsley, a cornerstone of the transaction, it includes the Boddington bauxite mine and the Worsley refinery, providing full integrated mining and refining. This was the largest EBITDA contributor in 2025 of the acquired assets and represents a significant source of long-term value in the portfolio. In Brazil, the acquisition includes additional interest in the IMR refinery and smelter, which we already operate, and will result in Alcoa's 100% ownership in the IMR smelter. South32's interest in both assets generated approximately $1 billion of revenue and $100 million of EBITDA in 2025. The associated interest in MRN supplies bauxite into the IMR refinery. This is largely a consolidation of ownership and optimization of an existing system with limited operating risk. The acquired interest in MRN is subject to a right of first refusal of other shareholders, which if exercised will result in Alcoa not acquiring that interest in MRN. We have considered and planned management of bauxite supply and related operational manners under both the scenario where we acquire this interest in MRN and where we do not acquire this interest in MRN. With the hillside smelter, we are adding meaningful volume and cash flow generation. In 2025, Hillside generated approximately $2 billion of revenue and $200 million of EBITDA, and in the current pricing environment is delivering strong cash generation. This asset adds scale to our smelting portfolio in a way that is expected to be cash flow accretive immediately. Hillside does introduce a new geography for Alcoa, but from a technical standpoint, it uses the same AP30 smelting technology that we've operated for decades at two of our smelters. Across the full portfolio, production at these assets has been stable and predictable over the past five years, which we view as an important indicator of operational reliability and downside resilience. Simply put, these are high-quality, well-understood assets with strong operating histories, and we see a clear path to integration, all of which support our confidence in the value creation potential of this transaction. This deal is attractive today, and it becomes even more compelling as we capture the synergies. We expect to begin realizing benefits quickly, targeting approximately $50 million of annual run rate cost savings within the first 12 months after closing through procurement, logistics, and commercial optimization. In addition to the benefits of adding scale, we bring together the best of both organizations. By combining Alcoa's high-performance culture and commercial discipline with the deep asset knowledge, local expertise, and strong operating cultures of the South32 teams, we have an opportunity to build a stronger, more capable company for the long term. There is also meaningful value to be realized from applying the best of both concept across the portfolio. By leveraging best practices and technology and adding South32's expertise to our centers of excellence, we expect to improve productivity, lower costs, and enhance operational stability. The largest long-term opportunity comes from optimizing the Western Australia asset base. Combining mine planning and development creates opportunities to access higher quality ore, improve efficiency, and optimize capital deployment over many years. These synergies are actionable, beginning shortly after closing and building over time. They reinforce our conviction that this transaction can deliver substantial shareholder value. Over the coming months, we will work diligently and respectfully to prepare for integration. We recognize the strength of the South32 workforce and believe that our combined capabilities, shared values, and performance culture position us to build an even stronger Alcoa and create long-term value for employees, communities, customers, and stockholders alike. The acquired assets bring meaningful scale. On a calendar year 2025 pro forma basis, EBITDA would have been higher by approximately 45 percent, revenue by 28 percent, aluminum production by more than 50 percent, and aluminum production by nearly 40 percent. That scale strengthens our market position while improving the overall quality of our portfolio. Equally important, we're adding high-quality, low-cost assets that improve our position on both the alumina and aluminum cost curves, which translates into greater resilience and stronger free cash flow generation through the cycle. That cash generation gives us flexibility. It supports our commitment to maintaining a strong balance sheet, provides a clear path for deleveraging after completion of the acquisition, and ultimately enhances our ability to create value for shareholders over the long term. At the agreed consideration, the transaction implies an enterprise value of approximately $4.7 billion, including assumed liabilities but before the contingent value rate, or up to $5.4 billion, assuming the maximum CVR payout. Against 2025 EBITDA of the acquired assets of roughly $900 million, that translates into an acquisition multiple of approximately 5.2 to 6.1 times EBITDA, depending on the ultimate CVR outcome. Importantly, that's before giving credit for any of the synergy value we've identified. When we compare that valuation to Alcoa's own trading history, the transaction is being executed at or below our average through-cycle valuation. As the chart shows, our average enterprise value to EBITDA multiple over the last five years has been approximately 6.3 times, which is above the acquisition multiple we're paying today. We also structured the transaction so that a portion of the value is contingent on future commodity prices. The CVR aligns consideration with market outcomes and allows us to share upside with the seller while protecting value for Alcoa shareholders if commodity prices are lower than expected. The way we look at it is simple. We are acquiring an evaluation that is attractive relative to both our own trading history and the quality of the assets we're buying. To conclude, this is the right transaction for Alcoa and an important step forward in strengthening our position as the leading pure play upstream aluminum company. It brings together high quality assets, clear industrial logic, actionable synergies, and compelling financial benefits. Most importantly, it improves the quality, scale, and resilience of our portfolio and enhances our ability to create long-term value for Alcoa shareholders. We believe this transaction reinforces Alcoa's position as the investment of choice in aluminum for investors seeking exposure to a high-quality, globally competitive upstream portfolio. With that, let's open the floor for questions. Operator, please begin the Q&A session.

Operator

We will now begin the question and answer session. To ask a question, you may press star, then 1 on your phone. If you're using a speakerphone, please pick up your handset before pressing the keys. To withdraw your question, please press star, then 2. When called upon, please limit yourself to two questions. And the first question comes from Alex Hacking at Citi. Please go ahead.

Alex Hacking, Analyst — Citi

Yeah, thanks, Bill, and congratulations on the transaction. So you mentioned that you expect the transaction to be cash flow accretive. You mentioned that the Hillsdale smelter is generating positive free cash in the current environment. How about the other assets? Thank you.

William Oplinger, CEO

Thanks, Alex. Hillside is generating significant free cash flow currently. The Alumar refinery is our most EBITDA positive refinery that we have in the system currently. So, Alumar is currently EBITDA positive. Alumar smelting is significantly EBITDA positive under the current scenario. And what am I missing? Worsley, when we look at Worsley's numbers, they're around break even at a lower 300. So, let's say a 310, a 315. We believe they're around break even. At a 330, they would be EBITDA positive. And Alex, just to be clear, and if I could add on to it, you know, when we step back and look at this transaction, we think that we are acquiring fantastic long-term assets at a really reasonable price. So if you do the math, there's a variety of different ways to cut it, but we're acquiring smelting capacity at about $1,850 per ton. We're acquiring refining capacity at $600 per ton. I would tell you both of those numbers are below what the Chinese build in Indonesia at today. Western world smelting capacity, new capacity, probably goes for $7,000 to $8,000 a ton, and we're acquiring at $1,850. Illumina refining around the world, Western world Illumina refining, probably costing between $1,500 and $2,000 a ton. We're acquiring at $600 a ton. So while in the Illumina space, near-term cash flows have been constricted, if you look at the history of this business, over the history of the business, there's been significant value created in the bauxite and Illumina side of the business.

Alex Hacking, Analyst — Citi

Thanks for the call, Bill. Super helpful. Could you maybe discuss the power contract in South Africa? Thank you.

William Oplinger, CEO

Our contract runs through, I believe, 2032 or early 2030s. So it's got a strong power contract today. You may have seen that some of the ferrochrome smelters have been able to negotiate really good power contracts in South Africa recently. We're confident that we'll be able to repower the hillside smelter, and clearly we'll start working on that towards the end of the decade.

Operator

The next question comes from Timna Tanners at Wells Fargo. Please go ahead. Yeah, hey, good evening.

Timna Tanners, Analyst — Wells Fargo

I want to take a step back and look at this deal as a bit more of an Illumina transaction. It does acquire more Illumina volumes, even adjusted. And, you know, Illumina has been a challenging market. You've been pointing that out in your last several decks that the cost curve is in the red for about 50 percent of production. So why is this the right time to add more aluminum capacity, Illumina capacity? What do you seem to support that decision?

William Oplinger, CEO

Two things, Timna. You need to step back and take a long term view of these assets. But if you go back probably two years ago, I think most of our investors were saying to us, you need to invest more in the bauxite and alumina business because it's your best returning business. Over time, the value shifts in the value chain between mining, refining, smelting. You never quite know where the value will occur because you don't know where the constraint will be. Right now, the constraint is in smelting capacity. Hence, the values accruing to smelting. If you look back over history, 2018, 2024, significant value created in accruing to the bauxite and Illumina business. So we don't look at this as necessarily as a near term acquisition, even though it's going to be accretive both on cash and earnings. It is a long-term acquisition, and on top of that, so all the numbers that I just quoted, $1,800 a ton for smelting, $600 a ton for refining, none of that includes the synergies that will be created. We're unlocking synergies that if you're a South32 owner or an Alcoa owner, you can't unlock yourself. We're going to unlock $900 million of synergies, and those synergies are going to come in really three areas. The first is the near term. It's going to be procurement, logistics, commercial. The second is going to be applying our expertise to these assets. We have 130 people in centers of excellence that are largely based in Western Australia that all they do is work on improving of our assets. We'll be able to do that now with more assets. But thirdly, the most compelling is when you look at mine planning specifically in Western Australia, the Worsley and Boddington site is co-located with, I should say, adjoining our existing sites. So if you look at the map, their bauxite lease is right next to our bauxite lease. We think over the next decade, we're going to be able to unlock significant value, both at Worsley, but at Pinjera and Wagerup as we optimize the mine plan. So that's the exciting thing about this transaction. I ran through the mine plan two weeks ago with the team in detail. We have a clear mine plan with or without these assets. Now that we're able to announce these assets, the mine plan is that much stronger.

Timna Tanners, Analyst — Wells Fargo

So appreciate that. And just a follow-up, though, on the Illumina market, you know, irrespective of those positives and the ability to capitalize on those assets, there are some irrational behaviors we've seen in Illumina over the year. Is that something that you're expecting to continue and do all the assets fit? Because you also mentioned optimizing portfolios and rationalizing, perhaps, or am I misunderstanding? Do all the assets fit, and how do you think about some of the irrational behavior outside of your footprint?

William Oplinger, CEO

So when you say irrational behavior in Illumina, I would suggest to you that the Illumina market has been very rational over the last five to ten years. What you see in the aluminum market when prices dip, you see curtailments. And to some extent, you've seen some of those curtailments in China already. The aluminum pricing just recently has stabilized and recovered. So we're now looking at aluminum prices that are $330 a ton up from $305. Nice thing about the aluminum market is that it's not storable. Unlike the aluminum business where you can have inventories that will overhang for quarters or years, Illumina reacts quickly to supply and demand changes. So where you saw real fly-ups in Illumina in 2024 as there was significant supply deficits, recall at those times we saw Illumina prices $700, $800, $900 a ton, and that's where a significant value was created. These assets, combined with Panjera and Wagerup, which will be getting back to a first quartile style assets, will generate significant value for the shareholders over the long term. Panjera and Wagerup are in a little bit of an odd situation currently because of the box site quality, but I've been in Australia for the last month. I'm convinced that we're going to get through our permitting process, and we will be back into strong bauxite quality for the end of the decade.

Operator

The next question comes from Bill Peterson and J.P. Morgan. Please go ahead.

Bill Peterson, Analyst — J.P. Morgan

Yeah, good evening, and thanks for taking the question, and congrats on the deal. On the synergies, for the $50 million in annualized the first year, is there a way to break it down between COGS and OPEX? I mean, I think you said procurement, logistics, and commercial. And then for the full 900 million in synergies, I guess is there a way to break it out by region or set in other ways or particular assets or regions that carry more weight or offer more synergies? Just trying to get a sense for the crown jewels, if you will.

William Oplinger, CEO

The 50 million we've already identified, we're going to be able to attain it very quickly and it's going to flow through COGS. So you're going to get it in COGS. Over the long term, the biggest opportunities for the synergies are in Western Australia. Be clear, these are not job synergies. We're not looking at massive rationalization of jobs. What we're looking at is applying our expertise to running Worsley in a way that we can create capacity and make it more efficient. In addition to that, the other big opportunity in the six- to ten-year timeframe is that mine planning, being able to utilize the three mines that we have, that we will have in Western Australia. So remember, we have Huntley, Willowdale, and now we'll be able to have Boddington. If you simply look at the Australia and ML1SA and the bauxite lease of South 32, they are adjoining each other. There are tremendous opportunities to optimize the mine plan with those. So that's where the lion's share of the synergies. Not a lot of synergies in Brazil. We are so small synergies there, maybe some opportunities to creep hillside. But the big lion's share of the synergies is in Western Australia. And I should come back to just remembered, Timna specifically asked me about rationalization of assets. There's no rationalization of the portfolio considered at this point.

Bill Peterson, Analyst — J.P. Morgan

Yeah, and maybe to follow up directly on the point about Western Australia, this still would mean that you would be pursuing the new mine regions in Mayara, North, and Holyoke. Is that right, or would these be – are they part of that mine plan you spoke of, or would they be deprived?

William Oplinger, CEO

No, in the short term, we will continue to pursue our Part 4 permits and the new mine moves into Mayor North and Holyoke. That's what gets us into the Better Box site. This transaction does not impact that. As we look forward, you know, six to ten years out into the future, we will be able to optimize the three mines. But this has no impact on our permitting and short-term box site opportunities.

Operator

The next question comes from Chris LaFemina at Jefferies. Please go ahead.

Chris Lafemina, Analyst — Jefferies

Hey, Bill. Congrats, and thanks for taking my questions. So the first one I have is in the press release, you note that you have the $3.1 billion bridge loan, which you intend to replace with cash from the balance sheet and permanent debt financing prior to the transaction close. So you're adding on 2025 numbers $900 million of EBITDA and taking on $3.1 billion of debt, and that doesn't include the contingent payments that you might have to make later. And I'm just wondering first whether an equity issuance at some point might be part of the strategy to recapitalize the balance sheet, or is that simply not the base case at the moment?

Molly Beerman, CFO

So, Chris, that's Molly. The base case does include the $1 billion value of equity. As we think about the, we'll have the bridge loan commitment in the near term, but when we replace that, we will look at the mix of cash from the balance sheet, as well as long-term unsecured notes for the balance of the debt portion of the consideration.

Chris Lafemina, Analyst — Jefferies

Okay, so the $3.1 billion, we should just look at that as being, you know, it's going to be debt, not equity, basically.

Molly Beerman, CFO

with a mix of cash on the balance sheet. We've got great projections for cash generation through the end of this year, even into 27. So we will optimize cash from the balance sheet as well in that mix.

William Oplinger, CEO

And Chris, if I could jump in on that one also. So when you think about the 3.1, we are going to be significantly cash flow generative in the second half of this year. You know that with the higher prices, we built up significant working capital. If prices remain where they are, we should see that working capital flow out in the second half of the year. In addition to that, if you then extend your time horizon and think about the future a little bit, we've talked about $500 million to $1 billion of cash from our asset sales in the data center area. On top of that, we're right around the corner in mid-2028 being able to monetize the modern shares. So the first tranche of modern shares is worth about $500 million. first. That is in mid-2028. So this 3.1, which will be a mix of cash from the balance sheet and some borrowing, is very manageable for the company. I think that when we consider the earnings power, and then on top of that, we didn't really talk about the lockbox, but depending on what metal prices look like, the lockbox could have significant cash in it. So very manageable at the $3.1 billion level. Molly and I are completely comfortable with that leverage level. We've also run through the RAS-RAS process with the rating agencies,

Operator

and we feel good there. The next question comes from John Tomazos at John Tomazos Very Independent Research. Please go ahead. Thank you for taking my question.

John Tomazos, Analyst — John Tumazos Very Independent Research

Could you explain the duration of the Hillside electricity contract and update us on the duration of the Alumar electricity contract, please?

William Oplinger, CEO

I'll take Hillside first. Molly will take Alumar because I would be guessing. But Hillside is through 2032. And, John, as I said to a prior question, ferrochrome smelters in South Africa recently got some pretty strong power contracts. With the strategic importance of Hillside to South Africa, I am confident that we will be able to repower Hillside very effectively. And then when you look at the valuations that we are paying for these assets, we have a very conservative estimate of what power pricing would be in Hillside post-2032 that I think we will be able to beat. Alumar, Molly, when does Alumar expire?

Molly Beerman, CFO

Yeah, I'm going to correct you on Hillside. It's through 31. And then on Alumar, it's through 2038. We signed a 15-year contract there when we started the restart.

John Tomazos, Analyst — John Tumazos Very Independent Research

The South 32 release mentions the assumption of $1.2 billion of reclamation liabilities. Would that be accurate on Alcoa's books too?

Molly Beerman, CFO

So, John, the $1.2 billion on South32's books is both asset retirement obligations as well as environmental reserves. Now, they're on IFRS accounting, so they do have different estimation techniques. They have to include conditional AROs, which assumes that a closure date is known and their estimates have to include that. U.S. GAAP does not require that, so they will come onto our books at about $400 million.

Operator

Once again, to ask a question, please press star then 1, and our next question comes from Nick Giles at B-Riley Securities.

Nick Giles, Analyst — B. Riley Securities

Yeah, thanks, Operator. Guys, congrats on the deal here. Just back to the synergies, the life of asset planning, the benefits are fairly long dated, so how do we set the baseline, or what are the ways in which we can track progress on this front? You know, where does that sustaining CAPEX and operating cost profile really stand today?

Molly Beerman, CFO

So on the long-term mine plans, we are looking at a 40-year life of mine plan. So you look at the savings over that, obviously the NPV on that comes back to today at a smaller number. But we have considerable spend expected in the early to mid-2030s for a mine move that we believe we'll be able to modify and have as much lower costs. So remember, mine moves are hundreds of millions of dollars at a time. And as we look at the plan, we believe that we'll be able to optimize those mine moves.

Nick Giles, Analyst — B. Riley Securities

Thanks, Maui. And then maybe just to follow up, I think, Bill, you said that you're not ready for any rationalization of supply today. But I was curious if you are ready for optimization and specifically as it relates to San Ciprian, how this deal could kind of impact the outlook there.

William Oplinger, CEO

There's no impact from this deal on San Ciprian. You've heard me talk pretty extensively and Molly on San Ciprian. We have the viability agreement on the smelter that we continue to live up to. At this point, the smelter is cash flow generating. The refinery negatively impacts that. The refinery at these levels is. So the target is to have a cash neutralization program for 2027. And so this deal does not have an impact on SanSifrin.

Operator

The next question comes from Richard Burke at Bloomberg Intelligence. Please go ahead.

Richard Bourke, Analyst — Bloomberg Intelligence

Yes, thank you for taking my question. On the slide, you gave production of the assets that you're acquiring over the last five years. I was wondering if you had a range of EBITDA for those same assets that, you know, in 2025 that produced $900 million?

Molly Beerman, CFO

It is approximately $900 million. Actually, maybe rounding down to $800 million. And South32 actually included that in their release. They have the average for 2021 to 2025. They're using it to calculate their multiple.

William Oplinger, CEO

And just remember, 2021 included a COVID year, and the world's not expecting a COVID year to repeat.

Richard Bourke, Analyst — Bloomberg Intelligence

Okay. Also, is there a floor ceiling on the stock price that has to be maintained?

William Oplinger, CEO

No.

Richard Bourke, Analyst — Bloomberg Intelligence

And the synergy program, what's your cash cost to implement the synergy program?

Molly Beerman, CFO

There are minimal cash costs. We will in the middle category on slide six where we have the process technology. We have savings there, and that's about 30% of the total NPV. We will have some CapEx spend to get those process technology benefits, but it's not hugely significant.

William Oplinger, CEO

And as far as one-time integration costs associated with the systems, we've netted the one-time integration costs $1,000 of Synergy. So that is baked into our Synergy's estimate.

Molly Beerman, CFO

Bill, there was a slight gap in the line. I just want to fill in that the integration costs are netted against the $900 million in synergies.

William Oplinger, CEO

Thank you. And I'm joining you from Australia today. So if there are any breaks in the line, we've got Pittsburgh on the line and Australia on the line. So we apologize if there are any technical issues.

Operator

The next question comes from Jacob Lee at Bear and Joey. Please go ahead.

Jacob Lee, Analyst — Bear and Joey

Happy Omoly and team. Thanks for the question. I think you talked to Bigger Synergy being in WA just now, just trying to dig into that a bit more. Boxite from Bonington, are they complementary to Ocoa's needs at Pajara and Whizra, or sort of different quality of boxite? Is there early benefits you could pick up from sort of early access to boxite in Bonington? For example, I think you previously talked about whether or not cost benefits from picking up better quality of boxite. Thanks.

William Oplinger, CEO

Yes. So, to be clear, Worsley and Pinjera use different types of bauxite. We use what's called a granitic bauxite in Pinjera. Worsley uses what's called a greenstone bauxite. Our mining lease has greenstone bauxite in it. Their mining lease has granitic bauxite in it. We will be managing the blending of those bauxites to maximize and optimize the output of Worsley and Pinjera. So there are tremendous opportunities to be able to blend the bauxite grades to achieve a very favorable outcome at both Pinjera and Worsley.

Jacob Lee, Analyst — Bear and Joey

Thanks, Bill. Just to follow up on that. So does this deal somewhat simplifying your business in WA from other perspectives, such as permitting of new money areas in Mearnal North, if any? Thanks.

William Oplinger, CEO

What it does is, first and foremost, and I've already made some phone calls this morning with senior leaders in Australia, is it strengthens the Australian business significantly. Having these assets together in Australia will make them more competitive globally, and that's a positive for Australia. So the permitting process for our existing assets will continue to run. We have a Part 4 permit that we're working on to be able to move our mines to Meijer North and Holyoke. The permitting process is largely completed for South 32. That's one of the big positives, that these assets have gone through their permitting process. So I think that the majority of our stakeholders really understand the rationale for this deal and are excited about the opportunity to make a stronger Western Australian bauxite and alumina business.

The next question comes from Mitch Ryan at Jefferies. Please go ahead.

Mitch Ryan, Analyst — Jefferies

Morning all. Thank you for taking my question. I know that the deal is structured so that there is no Alcoa shareholder vote. Can you just talk me through that process and the rationale for that?

Molly Beerman, CFO

So the shares that we will be issuing is about 6% of Alcoa's outstanding share, so that does not cause us to require a vote.

William Oplinger, CEO

And in the case of South32, they will be going to a shareholder vote. We expect that in the October-November timeframe. And their board has recommended this transaction to their shareholders. So that's one of the milestones that will occur between now and closing.

Bill Peterson, Analyst — J.P. Morgan

Okay. Thank you.

This concludes our question and answer session. I would like to turn the conference over to Mr. Opplinger for closing remarks.

William Oplinger, CEO

Thanks to everybody for joining us so quickly to discuss this transaction. If you can hear it in our voices, Molly and I are extremely excited about the opportunity that this brings. We think that this is the right transaction. It is a great strategic fit. It provides compelling financial returns immediately. And on top of those financial returns, we've got $900 million of synergies that we've identified. We've spent a decade putting the company in a position to be able to execute upon this type of a transaction. And in our view, we're able to capture upside value for our shareholders that we wouldn't be able to capture on our own. That's why it's such a critical transaction. I appreciate your time today, and we'll be talking to you over the next few days, I'm sure.
