アルコア（AA）2026年第3四半期決算説明会：堅調な操業、キャッシュフロー、AliGroupの進捗

重要なポイント

• アルコアの2026年第3四半期売上高は37億ドル、アルコアに帰属する純利益は4億8300万ドル、普通株1株当たり利益は1.81ドルとなりました。
• 調整後EBITDAは7億8900万ドルとなりました。堅調な操業とアルミナ価格の上昇が、アルミニウム価格の下落、出荷量の減少、および炭素コストの増加を一部相殺しました。
• 操業モメンタムが改善しました。アルミニウム生産量は前四半期比で約1万5,000メトリックトン増加し、アルマール（Alumar）製錬所の再稼働が完了したほか、ピンジャラ（Pinjarra）精製所の安定性が回復しました。
• 当四半期のフリーキャッシュフローは4億7200万ドルに達しました。期末現金残高は44億ドルとなり、これにはアリグループ（AliGroup）の買収資金に充てることを目的とした9月の社債発行による26億ドルが含まれています。
• 経営陣は、精製所の安定化と製錬所の増産に支えられ、第4四半期はアルミナとアルミニウムの両部門で生産量および出荷量が増加すると見込んでいます。
• アルコアは、アリグループの買収を2027年前半に完了する予定です。買収完了後、経営陣は迅速なデレバレッジ（負債削減）を資本配分の最優先事項にすると述べています。

主要財務データ

事業および操業パフォーマンス

アルコアは年初来で6つの生産記録を達成し、アルミニウム生産量を前四半期比で約1万5,000メトリックトン増加させました。同社はアルマール製錬所の再稼働を完了したほか、ピンジャラ精製所の安定性向上により、アルミナ部門の調整後EBITDAが9,500万ドル増加しました。

アルミニウムの出荷量は前四半期比で減少しました。これは、第2四半期に第1四半期から再配置された約3万メトリックトンの在庫が含まれていたためです。経営陣は、これを除けば第3四半期の出荷量は堅調であったと述べています。

アルミナについては、アルミナ価格指数（API）が前四半期比で上昇し、1メトリックトン当たり約370ドルとなりました。経営陣は、公表された減産、プロジェクトの遅延、インドネシアでの新規供給を巡る不透明感により、中国以外の市場は第4四半期から2027年にかけてさらに逼迫すると予想しています。中国市場では、精製能力の増強に伴い生産量と在庫が増加し、引き続き十分な供給が行われました。

世界のアルミニウム在庫は消費量の約42日分と、歴史的な低水準にとどまりました。アルコアは、ほとんどの製品が完売しているか厳しい契約下にあるとし、前年同期と比べて利用可能な数量が大幅に減少していると述べています。需要は包装および電気市場が牽引し、輸送部門は堅調さを維持した一方、ヨーロッパの建設部門が最も弱い最終市場となりました。

アルコアは、マセナ・イースト（Massena East）敷地の一部を最大3億1,500万ドルで売却する正式契約を締結しました。同社は、条件を満たした上で6ヶ月以内と見込まれる売却完了時に5,000万〜6,500万ドルを受け取り、残りの対価は2020年代末までに支払われると予想しています。本取引は、2030年までに資産流動化によって5億〜10億ドルを調達するというアルコアの目標を支援する初の取引となります。

業績予想（ガイダンス）

経営陣は、第4四半期において両事業部門で生産量および出荷量が増加すると予想しています。アルミナ精製所の安定稼働は継続すると見込まれており、製錬ポートフォリオは増産とコスト規律の恩恵を受ける見通しです。

第4四半期のアルミナ事業パフォーマンスに関する横ばいとのガイダンスには、市場価格変動は含まれていません。地域間の保守作業の移動が出荷量の改善によって相殺される見込みであるため、アルミナ価格の上昇分は別途業績に反映されることになります。

アルミニウム部門について、経営陣は第4四半期のパフォーマンスコストが約1000万ドルの追加炭素コストを含め、約3000万ドル増加する見込みであることを明らかにしました。アルミナ部門のパフォーマンスコストは横ばいで推移する見通しです。

アルコアは、第4四半期に運転資本が少なくとも約10日分回収されると見込んでいますが、キャッシュへの影響は年末のコモディティ価格に依存します。

アリグループの買収は、予定通り2027年前半に完了する見込みです。アルコアは26億ドルの負債による資金調達を完了し、その調達資金と手元資金を組み合わせて31億ドルの現金対価を支払う計画です。経営陣は、当四半期末時点のロックボックス（Locked-Box）価値を3億ドル以上と見積もっています。

リスクと注目点

• アルコアは9月16日にアルマール製錬所で死亡事故が発生したと報告しました。経営陣は、安全管理、リーダーシップの振る舞い、および説明責任の強化を進めていると述べています。
• 西オーストラリア州における採掘許認可の取得プロセスは想定以上に時間を要しており、2027年までずれ込む見通しとなっています。経営陣は、2027年半ばまでに承認が得られればボーキサイトの供給、品質、コストにこれ以上の重大な影響は生じないとみていますが、予備期間として設けた6ヶ月を超えて遅延が続いた場合、より厳しい操業上の意思決定が必要になる可能性があります。
• 中東におけるアルミニウム生産の回復時期は依然として不透明です。経営陣はまた、ホルムズ海峡を経由するアルミニウム輸送の継続的な混乱を挙げました。
• インドネシアは2027年に約150万メトリックトンの製錬能力を追加する可能性があります。経営陣は、約7,500万メトリックトンの世界市場はこの増加分を吸収できると考えているものの、その規模は無視できない大きさであるとしています。
• 2026年の中国のアルミニウム生産量は約4,580万メトリックトンと推定され、当局が限定的な生産上限超えを容認していると見られることから、公称上限を約40万メトリックトン上回りました。
• アリグループの買収完了は引き続き規制当局の承認を条件としています。アルコアは現時点で懸念材料（レッドフラグ）は見当たらないとし、中国当局の承認は不要であることを確認しました。

アナリスト質疑応答のハイライト

資本配分：経営陣は自社株買いが当面の最優先事項ではないと述べました。アルコアはまずアリグループの買収を完了させ、その後、フリーキャッシュフロー、ロックボックスの現金、資産売却益、およびマーデン（Ma’aden）株式の流動化の可能性を活用して、迅速なデレバレッジに注力する方針です。

アリグループの統合：アルコアは統合管理オフィスを設置し、買収した資産を初日から運用できるよう準備を進めています。法的な買収完了後は、サウス32（South32）との18ヶ月間の移行サービス協定によりサポートが提供されます。

マセナ・イーストの採算性：初期プロジェクトには少なくとも180メガワットの許認可が必要であり、300メガワットおよび200メガワットの容量拡張の可能性があります。同敷地は最終的に635メガワットに達する可能性があります。アルコアは修復義務を維持しますが、売却される土地は環境修復作業をすでに完了しています。

北米の関税：経営陣は米加間の協議の状況を把握していないと述べました。カナダ産アルミニウムが免税または低関税の適用を受けたとしても、米国の限界需要分（マージナルトン）は引き続き北米域外から供給され、中西部プレミアムを支えることになるとアルコアは考えていますが、経営陣はこれを推測の域を出ないとしています。

Good afternoon, and welcome to the Alcoa Corporation Third Quarter 2026 Earnings Presentation and Conference Call. [Operator Instructions] Please note, this event is being recorded.

I would now like to turn the conference over to Louis Langlois, Senior Vice President of Treasury and Capital Markets. Please go ahead.

Louis Langlois

Thank you, and good day, everyone. I'm joined today by William Oplinger, Alcoa Corporation President and Chief Executive Officer; and Molly Beerman, Executive Vice President and Chief Financial Officer. We will take your questions after comments by Bill and Molly.

As a reminder, today's discussion will contain forward-looking statements relating to future events and expectations that are subject to various assumptions and caveats. Factors that may cause the company's actual results to differ materially from these statements are included in today's presentation and in our SEC filings. In addition, we have included some non-GAAP financial measures in this presentation. For historical non-GAAP financial measures, reconciliation to the most directly comparable GAAP financial measures can be found in the appendix to today's presentation. We have not presented quantitative reconciliations of certain forward-looking non-GAAP financial measures for reasons noted on this slide.

Any reference in our discussion today to EBITDA means adjusted EBITDA. Finally, as previously announced, the earnings press release and slide presentation are available on our website.

Now I'd like to turn over the call to Bill.

William Oplinger

Thank you, Louis, and welcome to our third quarter 2026 earnings conference call. Before discussing our results, I want to address the tragic fatality that occurred on September 16 at our Alumar smelter in Brazil. The loss of one of our colleagues has deeply affected all of us at Alcoa, and our thoughts remain with his family, friends and coworkers. We are a company grounded in our values, act with integrity, operate with excellence, care for people and lead with courage. Safety is fundamental to our values, and it guides how we run our business. There is no production target, financial results or business objective that is more important than ensuring every employee and contractor returns home safely every day.

Over many years, we have strengthened our safety systems and dedicated significant resources to improving safety performance. Those efforts have resulted in meaningful progress in many areas of our business. But when we lose a colleague, progress is not enough. I am personally committed to ensuring we learn from this event and take the actions necessary to strengthen our safety culture, reduce risk across our operations and hold ourselves accountable to the highest safety standards. This tragedy reinforces that safety requires relentless focus, constant vigilance and an unwavering commitment from every one of us every day.

With that commitment firmly in mind, I'll now turn to our third quarter results. We continue to build operational momentum and delivered strong third quarter performance. We achieved 6 year-to-date production records, increased aluminum production by approximately 15,000 metric tons sequentially, completed the Alumar smelter restart and delivered a significant performance recovery at the Pinjarra refinery. Together, these results demonstrate improving stability and disciplined execution across the portfolio.

We reached a definitive agreement for the sale of a portion of the Massena East site with potential cash proceeds of up to $315 million. We expect to receive the first $50 million to $65 million at closing, which is anticipated within 6 months, subject to customary permitting, regulatory approvals, key development and closing conditions. We expect to receive the remaining cash consideration before the end of the decade, although the agreement provides up to 7 years for commissioning. This is the first transaction supporting our target to generate $500 million to $1 billion from asset monetization by 2030.

The AliGroup acquisition continues to advance. The asset's strong first half 2026 performance reinforces our confidence in the strategic and financial rationale for the transaction. South32 shareholders approved the transaction, bringing us another step closer to our expected closing in the first half of 2027.

Let me now provide an update on our progress toward transaction closing. Since announcing the AliGroup acquisition on June 30, we have made meaningful progress towards closing. In September, we completed the $2.6 billion debt financing and canceled the bridge facility. Completing the financing early reduced execution risk and provides certainty around funding the cash consideration. We estimate that the locked box value was more than $300 million at the end of the quarter based on publicly available information, including production guidance provided by South32.

The regulatory approval process is progressing well across the relevant jurisdictions. Earlier this month, I met with President Ramaphosa and other key stakeholders in South Africa. Our engagement with stakeholders has been positive, and we remain confident in securing the required approvals to meet our expected first half of 2027 closing time line.

Our transition and integration teams are actively preparing for ownership of the assets. This work spans the organization and is focused on maintaining operational continuity, positioning us to capture the value of the combined portfolio and ensuring we are ready to execute following closing and beginning delivering synergies and broader benefits of the transaction. Until then, the businesses will continue to operate independently.

Now I'll turn it over to Molly to review the financial results.

Molly Beerman

Thank you, Bill. Third quarter revenue was $3.7 billion, with a sequential change primarily reflecting lower metal prices. In the Alumina segment, third-party revenue increased by 7% to $680 million, resulting from higher realized alumina prices and higher alumina shipping volumes.

In the Aluminum segment, third-party revenue was $3 billion, primarily reflecting lower metal prices and normalized shipment levels following the second quarter's inventory repositioning, partially offset by higher value-add product premiums. Third quarter net income attributable to Alcoa was $483 million versus the prior quarter of $407 million, with earnings per common share increasing to $1.81 per share. On an adjusted basis, net income attributable to Alcoa remained strong at $485 million compared with $562 million in the second quarter.

Let's discuss the factors affecting adjusted EBITDA. Adjusted EBITDA was $789 million as strong operational performance and higher alumina prices partially offset lower metal prices. The Alumina segment adjusted EBITDA increased $95 million on higher realized alumina prices and improved operational performance at Pinjarra as we regained stability in the third quarter.

The Aluminum segment continued to deliver productivity gains, including higher molten production, improved stability and disciplined cost performance. These benefits were more than offset by the impact of lower metal prices, lower shipments and higher carbon costs, resulting in segment adjusted EBITDA of $862 million.

Moving to cash flow activities for the third quarter of 2026. We ended the third quarter with a cash balance of $4.4 billion, which includes $2.6 billion of cash proceeds from the bond issue completed in September. Together with cash on hand, the net proceeds from the bond issue will be used to fund a $3.1 billion cash consideration to the AliGroup acquisition at closing.

Securing the financing now avoids access and pricing risks in a volatile bond market. The quantum issue also reflects the strength of our balance sheet and cash position resulting from consecutive quarters of robust free cash flow generation. In the third quarter, cash from operations was $643 million, and free cash flow was $472 million, supported by strong EBITDA in the Aluminum segment, where the company was able to deliver metal prices to the bottom line.

Turning to our key financial metrics for the third quarter and year-to-date 2026. Return on equity through the first 9 months of 2026 was 25.3%. Year-to-date, we have returned $80 million in cash to shareholders through our regular quarterly dividend. The company generated free cash flow of approximately $600 million in the first 9 months of the year.

As we look toward closing the AliGroup acquisition, our strengthened balance sheet, secured financing and substantial cash position provide ample capacity to fund the transaction. This is the result of disciplined capital allocation, strong cash generation and consistent operating performance.

Moving on to the outlook. For the full year outlook shown here, we have made only minor adjustments for transformation expenses, depreciation, interest expense and capital expenditures. For the fourth quarter, we continue to expect strong operating performance across both segments, continuing the momentum from the third quarter. We are expecting higher production and shipments in both segments as the improved refining system stability is maintained and the smelting portfolio continues to deliver productivity through incremental output and cost discipline. While we expect some higher direct input costs from elevated market prices and planned maintenance to support continued operational stability, the underlying performance remains very strong headed into the final quarter of the year. Please refer to the business considerations on Slide 34 of this presentation for additional details on the fourth quarter outlook.

Now I'll turn it back to Bill.

William Oplinger

Thanks, Molly. In alumina, the market tightened outside China during the quarter, with the API increasing sequentially to approximately $370 per metric ton. We expect further tightening in the fourth quarter and into 2027, driven by announced curtailments and project delays and uncertainty in Indonesia around new supply additions. At the same time, recovering alumina production in the Middle East and continued smelter ramp-ups in Indonesia should support additional alumina demand.

While the timing of some capacity coming online remains uncertain, the overall market condition is constructive. China remains well supplied from within the region as new refinery capacity has increased production and inventories. This continues to create a clear divergence between softer market conditions in China and tightening fundamentals outside China. Bauxite prices also increased sequentially, with CIF China pricing reaching approximately $73 per dry metric ton. The increase was driven primarily by higher freight costs.

For Alcoa, strengthening alumina market conditions and improved operational execution create meaningful upside. Our focus remains on operating our refineries safely and reliably, sustaining the recent performance improvement at Pinjarra and maintaining disciplined cost management.

Moving on to aluminum. Aluminum prices moderated from recent highs, but remain supported by constructive market fundamentals. On the supply side, production is gradually recovering as Middle East smelters restart and Indonesian capacity ramps up. The timing of a full recovery to pre-conflict production levels in the Middle East remains uncertain.

Global aluminum inventories remained historically low at approximately 42 days of consumption, leaving the market with limited capacity to absorb further supply disruptions or stronger-than-expected demand. The Midwest, Rotterdam and Japan regional premiums have moderated from elevated levels, but remain supported by low inventories and regional deficits. This tightness is particularly relevant in North America and Europe, both of which remain structurally short of metal.

For Alcoa, our regional presence, reliable supply and differentiated product portfolio are important elements of our commercial value proposition. Our order book remains solid, with significantly less volume available for sale than at this point last year. Most products are sold out or tightly committed.

Packaging and electrical markets continued to lead demand. Transportation remains resilient, and construction, particularly in Europe, remains the softest end market. Customer sentiment is cautious, but constructive with continued interest in secure supply and long-term agreements.

Before we wrap up, I'd like to return to the 3 priorities we set at Investor Day nearly a year ago. First, operational excellence. As I stated at the top of our call, safety remains our top priority and the foundation of operational excellence. We are strengthening critical risk controls, leadership behaviors and accountability. We are delivering greater stability across the portfolio, setting production records and improving productivity.

We have now completed the restarts of both the San Ciprian and Alumar smelters. While the Western Australia EPA's review of our mine plan continues to advance, we are preparing our teams to execute the upcoming mine moves. The mining approvals are taking longer than expected. Several steps remain, including the appeals process and final ministerial decisions, and we now expect the process to extend into 2027.

Our confidence in ultimately securing the approvals has not changed. We have incorporated an additional 6 months of mining in current areas into our plans, and approvals by mid-2027 are not expected to further materially affect supply, quality or cost. We also have contingency plans available if needed.

Second, value-creating growth. At Investor Day, we were clear that we would pursue growth only where we see a compelling path to long-term shareholder value. The AliGroup acquisition reflects that discipline, and we will apply the same standard to any future opportunities. We will not pursue growth for growth's sake.

Third, disciplined capital allocation. We ended the third quarter with a strong balance sheet supported by a robust year-to-date free cash flow. We structured the AliGroup considerations such that pro forma leverage approximates a manageable 1.5x.

Following closing of the acquisition, delevering will be our priority. We expect to use various sources of cash such as free cash flow generation, locked box cash from the transaction, proceeds from additional transformation asset sales and the monetization of our Ma'aden shares to reduce debt over time. Given the stronger through-cycle cash flow generation of the combined portfolio, we will update our adjusted net debt target at the transaction closing.

The Massena East agreement also represents meaningful progress against our asset monetization strategy. These actions demonstrate that we are executing the strategy we presented at Investor Day and strengthening Alcoa for long-term value creation. To wrap up, we are proud of what we accomplished in the third quarter, excited about the opportunities ahead and confident in our ability to deliver value for our shareholders.

With that, operator, please begin the Q&A session.

Operator

[Operator Instructions] And our first question comes from Carlos De Alba with Morgan Stanley.

質疑応答

Carlos de Alba

So the first question that I have is on the guidance. So maybe flat alumina, it's a little bit surprising to us given what we believe has been higher spot prices in recent months. And I know there is some lagging effects there, but that was a little bit of a surprise to us. Maybe could you explain, is there any cost pressures that may be behind this, offsetting some of the improved top line?

Molly Beerman

So Carlos, our guidance of flat refers just to our performance elements and not the market. If you look at our Alumina segment, there are a couple of puts and takes. We have some maintenance moving between regions, but that is completely covered by our improved shipment performance. So overall, the performance elements are a net of nothing, so flat and consistent with the strong performance in the third quarter.

Carlos de Alba

And then...

William Oplinger

Just so it's clear, Carlos, it doesn't include the -- the guidance doesn't include pricing, right? So if prices get better during the course of the quarter and they're better today than they were a quarter ago, it will flow through.

Carlos de Alba

Right. Okay. Yes. I don't confuse them. We're not looking at the consensus and our estimates, this will happen. But okay, that makes sense. Then just I was curious to see aluminum production higher in the third quarter, but your aluminum shipments being a little bit lower. Was there any inventory build up, any delays in shipments, and maybe you will catch up a little bit more in this current quarter? Any color there would be great.

Molly Beerman

So Carlos, remember in the second quarter, we sold the inventory that we had repositioned in the first quarter. So that was about 30,000 metric tons. So that did not repeat in the third quarter. But we had a strong third quarter in terms of shipment other than that repositioning that did not recur.

Operator

The next question will come from Timna Tanners with Wells Fargo.

Timna Tanners

I think it's appropriate to touch base about the potential carve-out on aluminum prices or aluminum tariffs for Canada because that happened during the quarter. And it would be great to get your take on anything you know about whether or not that's still in discussions and what that could mean for Alcoa.

William Oplinger

Thanks, Timna. We don't know what discussions are going on between the U.S. and Canada. We've offered support to both governments to provide data and information to help them come to a conclusion on any discussion that may be going on.

What really matters is whether the U.S. will remain short, right? And if Canada were completely carved out or if Canada had a lower tariff, we believe that still, the marginal ton will come outside, from outside of North America. And therefore, the Midwest premium still should remain strong. But at this point, it's just speculation.

Timna Tanners

Okay. Fair. And then I also wanted to get your take on how you get comfortable with the Indonesia ramp-up that you alluded to. Some of the forecast is for some pretty aggressive volume increases. Does Indonesian government seem to be aware of the risk to the aluminum price, like what they saw with the nickel price in the last several years? What's your take on the additional supply and how much could come on in Indonesia and what time frame? And that would be great to get also your latest thinking on China producing over it's self-imposed cap on aluminum as well.

William Oplinger

Okay. Yes. So a lot of questions baked in there. When I look at the rest of this year, 2026, we've actually seen strength of alumina pricing due to the ramp-up of the smelters and the return of some of the capacity in the Middle East. So that's actually a positive for us.

In January, we'll give you a better view of what our full year supply/demand picture looks like. But to give you a little bit of a highlight, we are thinking that we are going to see probably 1.5 million metric tons of smelting capacity come online in Indonesia next year. On a 75 million metric ton market, that's -- it's a material number. But we think that the market will be able to absorb it.

And then you asked about the China cap. Hey, the Chinese smelters, it feels as if the China cap is more of a policy tool to set a limit than a firm cap in that they're allowing some of the Chinese smelters to creep a little bit. But not a massive jump in capacity. So for instance, we're seeing China capacity being -- or production being around 45.8 million metric tons in 2026. That's 400,000 tons over than the nominal cap level. But it seems that they're holding from a capacity side and allowing maybe a little bit of production creep.

Timna Tanners

Thanks. I always appreciate your perspective.

Operator

The next question will come from Nick Giles with B. Riley.

Nick Giles

Yes. Thanks, operator. The aluminum equities as a whole have been under significant pressure. So Bill, just curious where in terms of capital allocation, share repurchases would stand at this point?

William Oplinger

So we're going to -- and Nick, thanks for the question. We're pursuing the closure of the South32 AliGroup transaction in the first half of next year. Clearly, we went out and raised debt in order to be able to pay the cash component of that. Recognize the fact that cash component of that is $3.1 billion. We only raised $2.6 billion because we're going to use some of the cash from the balance sheet.

We will get that deal -- we anticipate getting that deal closed in the first half. And then the priority after that closure will be rapid delevering. And clearly, the cash generation that we are seeing today will allow us to delever rather quickly. We alluded to the fact that we think there's $300 million of cash in the lockbox. That will certainly go into the cash consideration. But at this point, the target is delevering.

Nick Giles

Understood. No, I appreciate that perspective, Bill. My second question was, you made a comment about the WA EPA approvals being pushed out by 6 months and that there were some contingencies baked in there. I was hoping you could expand on what those contingencies were? And what you would do in case that drags on further?

William Oplinger

So the contingencies are clearly that we are resequencing and modifying our mining activities. We're looking at different production schedules and really going to continue to dig in the mines that we're in. And we feel confident that will not have a negative impact or, I should say, a further negative impact on the bauxite supply or quality. Beyond the first 6 months, we'll have to make some harder decisions, and we're confident that we will get those approvals within the first 6 months of next year.

Nick Giles

Okay. Good to hear. I appreciate the color, and continued best of luck.

Operator

The next question will come from Katja Jancic with BMO Capital Markets.

Katja Jancic

Maybe starting on the contingency value as part of the acquisition. Is it fair to assume that, that is starting to accrue on the alumina side since the alumina price is now above the strike? Or how should we think about that?

Molly Beerman

Yes. Katja, if the current -- the third quarter average was about [ 32 20s ]. I can't remember the exact number, but that would yield about a $13 million payment for the first period, so not substantial.

William Oplinger

What, Katja was referencing alumina prices?

Molly Beerman

The alumina price. Sorry, there's nothing new on alumina. We've not reached that strike price.

William Oplinger

At today's level, Katja, [ 370 ] -- I'm sorry, [ 387 ] today, we're not at the strike price yet.

Katja Jancic

Okay. And then maybe on the asset monetization, I think in the past, you said that there are 2 other assets that could quickly follow Massena East. Can you provide an update on that?

William Oplinger

There's 2 other assets that could quickly follow Massena East. Yes. I'm just joking around, Katja. We just got we're pleased to be able to announce the Massena East transaction. And you can see from the way it's structured, it's somewhat of a complex transaction. It gives us some cash upfront, but it will give us cash further over the next 5 years as that data center first gets built and then gets increased in size. So it gives us a lot of upside.

There are 2 other ones that we believe that could happen quickly after that. We've not named those publicly. But now that we at least have an agreement and we have to get it closed, at least we have an agreement on Massena East, we're going to focus on those next 2. So more to come.

Operator

The next question will come from Bill Peterson with JPMorgan.

William Peterson

Maybe actually taking you back on the Massena East agreement. Will you know the, I guess, the final amount upon the approval of the capacity? Or is this something that as it grows the potential for, I guess, up to the $250 million additional? I'm just trying to get a sense of when we'll know -- or when we'll know what kind of value you get.

And I guess, maybe more importantly, is this going to be kind of a similar template for these future agreements? Or is this maybe viewed as more of a one-off?

Molly Beerman

Bill, I'll start with the -- on the size, we do have a -- the permitting, initially, the minimum will be 180 megawatts. And then we have 2 step-ups potentially, another 300, and then another 200. So the site could be up to 635 megawatts. So depending on how the permitting and approvals go, then we will know the size. But the first payment at closing will be based on the initial permitting and will be at that minimum level initially.

William Oplinger

And as far as your question goes on whether this is a template, I think the answer, Bill, is a resounding now that there is not a particular template for data center sales. What we are finding is that in order to maximize value out of each site, you have to really negotiate particular parts of the agreement on each site. And so there may be out of 1 of those 2 that are coming up, similar structures, but we would also be pushing structures that would be more cash upfront and less future value. So there's not a single template for these transactions because each site has its own complexity.

William Peterson

Okay. Well understood. Appreciate that. And then I want to kind of understand some of the cost guidance for alumina and aluminum. And I think it's around $30 million for each, but I'm trying to get a sense for how sticky they are? And I guess 1 -- in the case of aluminum, turned unpack, what higher the raw materials costs are. And then similarly with alumina with presumably caustic and how sticky that may be?

Molly Beerman

Bill, if you think back, I'll start with caustic. In the second quarter, early after the war began, we saw the caustic price shoot up. That didn't stay though. It moderated pretty quickly. And so as I look at now caustic rolling through the P&L from those high purchase prices, we are not seeing a material sequential impact from that.

On the carbon prices, though, we are seeing elevation. When we guided in the third -- sorry, in the second quarter for the third, we thought it would only be about a $15 million impact. It ended up being just over $20 million. So carbon prices rolling through the P&L perspective, just over $20 million in the third quarter, and I have about $10 million more in carbon prices coming up further in the fourth quarter. Now fourth quarter purchase prices are still coming up, but very slightly. So we're not seeing the price escalation.

William Oplinger

And I just wanted to make sure I'm following back up. I thought your comment was something to the effect that $30 million increase in each segment. That's not the case. It's flat in Alumina and a $30 million increase in Aluminum. So I just wanted to make sure that, that's clear.

Molly Beerman

And of that 30 in Aluminum -- of that 30 in Aluminum, the 10 is the carbon.

Operator

The next question will come from Lawson Winder with Bank of America.

Lawson Winder

Thank you, operator, and Bill and Molly. If I could just follow up on the Massena East sale. One thing that wasn't clear is after closing, are there any environmental remediation or demolation or any sort of other legacy liabilities that sit with Alcoa? Or does that just pass on to the buyer?

Molly Beerman

No, we will keep the remediation responsibilities. We're continuing to remediate at the site. We are selling the part of the land that has already completed all of our environmental remediation work.

Okay. Fantastic. And then just 1 additional question. Again, of course, quite a bit of talk about the AliGroup opportunity and what an opportunity it is. When you look at the potential M&A opportunity set globally, I mean, do you continue to see other unique opportunities like AliGroup? And what sort of appetite does Alcoa have for further acquisitions post the closing of AliGroup?

William Oplinger

AliGroup is a big acquisition for us. Let us get this one closed before we start talking about other opportunities. What I really want to prove to the world through this acquisition is that, number one, we can grow this company. And number two, we can successfully integrate an acquisition. We have a pretty large team that's already in place that's working toward the integration so that when we close on day 1, we're going to be ready to integrate this.

And I mentioned in my prepared remarks that I was already over in South Africa, met with the President of South Africa, President Ramaphosa. Got a very good greeting introduction from him to the country and impressed on him that we're an aluminum company. We want to own Hillside. We want to be in Hillside for the long term, and we're committed to the aluminum industry. So we're going to focus on getting this one done first before we talk about other opportunities.

The next question will come from [ Richard Dutra ] with Barclays.

Unknown Analyst

Great. First question was basically, when you think about the acquisition and you've gotten approvals from South32 shareholders. Looking ahead, is there anything -- what are you doing right now in terms of potentially getting -- preparing for the eventual integration? Can you do some pre-planning? Or do you have to wait for any country approvals, the contracts on the procurement side? Anything that you can sort of do to help accelerate the capture synergies?

William Oplinger

Right. So we're really focused on 2 things currently between now and closing. One is gaining the required regulatory approvals. And there's about a dozen of those, and we have gotten some of those. And at this point, we do not see any red flags associated with getting the regulatory approvals.

Secondly, we have taken the last 60 days or so to stand up a significant integration management office, and they are preparing to be able to run those assets from day 1. And you think about the complexity of buying assets of these size, it's not a small undertaking. And so they're focused on being able to sell, make, account for bauxite, alumina and aluminum. And so it's not a small undertaking, and we're very focused on it. Molly, I know you're very close to this also. Do you want to make any other comments?

Molly Beerman

I'll just stand that we do have an 18-month transition service agreement with South32. So we will have coverage past legal day 1, but we're preparing now for all that work ahead so that we can. As soon as we close, start working closely with the teams on integrating the organization, the systems, processes and leveraging all of the synergies that we have identified.

William Oplinger

And I should have made it clear. Even pre-close, the 2 companies are working together to make sure that it's a successful, in their case, disposition, in our case, acquisition.

Unknown Analyst

That's very helpful. And then maybe if I could ask a question on the industry in general. You talked about the Middle East looking at ramping up [ sorting ] capacity. My question is, is there any constraints to that? Do they have adequate levels of raw materials to run those smelters at full capacity by -- what you're targeting in the first quarter of next year? Is the ongoing impact on shipping through the Hormuz? How does that impact their ability to get to those levels?

William Oplinger

I don't have a good answer for that question. You really are going to have to ask them how they plan to be able to do that. I think the one thing -- if I wax philosophically just for a second, I think the world has changed when it comes to aluminum within the Strait of Hormuz. And I think it's going to be a while before that completely gets normalized of flows in and out.

And so I think it is a big impact. You see it in pricing today. Even though prices are off from where they were, we're still sitting at close to $3,000 a ton. And so it has had a big impact, and I think it will still have a big impact going forward.

The next question is a follow-up from Timna Tanners of Wells Fargo.

Timna Tanners

I just wanted to follow up, if I could, on working capital. There was a big seasonal use in Q1. We really haven't seen much released. If we see aluminum prices stay at this level, the math and you could see, pretty nice release. So I just wondered, to the extent possible, if you could give us any color about what you might expect at these prices, prices hold into the fourth quarter?

Molly Beerman

Timna, if you look at on a days working capital basis and look back in history, we traditionally stepped down from like that 50-day level down into the 35 to 40 level. So I would expect we'll release about 10 days at least going into the fourth quarter. And obviously, the quantum there will depend on the pricing at the end of the year. But that's our expectation.

The next question is a follow-up from Carlos De Alba with Morgan Stanley.

Carlos de Alba

Yes. Just on the approval for the AliGroup transaction. Do you require China approval?

William Oplinger

No.

Carlos de Alba

All right. And then on the Massena East transaction, the step-up in capacity, is that solely based on regulatory approval? Or is -- or how do you make sure that it is not a decision of the data center? Maybe the economics change and they don't want to do the step 1 or step 2 of the increased capacity.

William Oplinger

Carlos, in my view, they are very interested in putting the maximum capacity within Massena East. The economics for them work much better as the facility gets larger. So it will be based on how quickly, I guess, a couple of things, how much demand there is, how much regulatory approvals that they get. So those are the 2 real big issues. And I guess how much capital they ultimately have. But my view is they want to see this as large as it possibly can be because I believe their economics get significantly better as it gets larger.

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

William Oplinger

Thanks, operator, and thank you all for joining our call. Molly and I look forward to sharing further progress when we speak again in January. This concludes the call. Thank you.

Operator

The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
