Executive summary

Alcoa Q3 FY26 — Operational Momentum and Strategic Acquisition Progress

Alcoa delivered strong Q3 FY26 results, marked by significant operational improvements, including production records and smelter restarts, alongside continued progress on the strategic AliGroup acquisition. The company secured financing for the acquisition and advanced asset monetization efforts with the Massena East sale. While navigating market price moderation and a tragic safety incident, Alcoa is prioritizing deleveraging post-acquisition close and maintaining disciplined capital allocation to strengthen its long-term value creation.

Segment performance

SegmentRevenueYoYQoQMargin
Alumina
Third-party revenue increased due to higher realized alumina prices and higher alumina shipping volumes. Adjusted EBITDA increased $95 million on higher realized alumina prices and improved operational performance at Pinjarra.
$680 million—7%—
Aluminum
Third-party revenue primarily reflected lower metal prices and normalized shipment levels (following Q2 inventory repositioning), partially offset by higher value-add product premiums. Adjusted EBITDA was $862 million, with productivity gains (higher molten production, improved stability, cost discipline) more than offset by lower metal prices, lower shipments, and higher carbon costs.

Deals & partnerships

South32 Acquisition of AliGroup assets (alumina refineries and aluminum smelters) $3.1 billion cash consideration

Alcoa completed $2.6 billion debt financing for the cash consideration. South32 shareholders approved the transaction. Regulatory approval process is progressing well across relevant jurisdictions.

Undisclosed buyer (data center developer) Sale of a portion of the Massena East site for data center development Up to $315 million (potential cash proceeds); $50M-$65M at closing; remaining $250M before end of decade Up to 7 years for commissioning of full capacity

The agreement is subject to customary permitting, regulatory approvals, key development, and closing conditions. The site could be developed up to 635 megawatts (initial minimum 180 MW, then two step-ups of 300 MW and 200 MW). Alcoa will retain environmental remediation responsibilities.

Risks & headwinds

Tragic fatality at Alumar smelter Q3 FY26

One colleague lost on September 16

Mitigation:Committed to learning from the event, strengthening safety culture, reducing risk, and holding accountable to highest safety standards.

Western Australia EPA mine plan approval delays Through CY27

Process expected to extend into 2027

Mitigation:Incorporated additional 6 months of mining in current areas; approvals by mid-2027 not expected to materially affect supply, quality, or cost; contingency plans available (resequencing/modifying mining activities).

Lower metal prices Q3 FY26

Primary driver for sequential change in Q3 revenue; offset Aluminum segment productivity gains

Mitigation:Focus on operational performance, productivity gains, and cost discipline to mitigate impact.

Higher carbon costs Q3-Q4 FY26

$20M impact in Q3, $10M additional expected in Q4

Mitigation:Underlying performance remains strong to absorb these costs.

Softness in construction end market Ongoing

Construction, particularly in Europe, remains the softest end market for aluminum demand

Mitigation:Focus on resilient markets like packaging, electrical, and transportation; secure supply and long-term agreements.

Uncertainty in Middle East aluminum supply recovery Ongoing

Timing of a full recovery to pre-conflict production levels remains uncertain

Mitigation:Global aluminum inventories remain historically low, supporting prices despite supply recovery efforts.

What to watch in Q4 FY26

Why it matters

Critical for long-term bauxite supply and operational stability in Western Australia.

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.

Q&A highlights

Why is alumina performance guidance flat despite higher spot prices, and why were Q3 aluminum shipments lower than production?

Alumina guidance refers to performance elements, not market pricing; flat performance reflects maintenance shifts offset by improved shipments. Q3 aluminum shipments were lower because Q2 included a one-time inventory repositioning of 30,000 metric tons that did not recur.

“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.”

Detailed narrative

AliGroup Acquisition Progress

Alcoa has made significant strides towards closing the AliGroup acquisition, including completing a $2.6 billion debt financing in September, which eliminated execution risk and provided funding certainty. The locked box value was estimated at over $300 million at the end of Q3. Regulatory approval processes are progressing well across jurisdictions, with positive stakeholder engagement in South Africa, reinforcing confidence in a first-half 2027 closing timeline. Integration teams are actively preparing for ownership to ensure operational continuity and value capture.

Asset Monetization Strategy

The company reached a definitive agreement for the sale of a portion of the Massena East site, with potential cash proceeds of up to $315 million. An initial $50 million to $65 million is expected at closing within 6 months, with the remainder by the end of the decade. This transaction marks the first step towards Alcoa's target of generating $500 million to $1 billion from asset monetization by 2030. Management indicated that two other asset sales could follow Massena East relatively quickly.

Operational Performance and Safety

Alcoa delivered strong operational performance in Q3, achieving 6 year-to-date production records and increasing aluminum production by approximately 15,000 metric tons sequentially. The Alumar smelter restart was completed, and the Pinjarra refinery showed significant recovery. However, the quarter was marked by a tragic fatality at the Alumar smelter on September 16, which reinforced the company's commitment to strengthening safety culture and accountability, making safety the top priority above all business objectives.

Alumina Market Outlook

The alumina market tightened outside China in Q3, with the API increasing sequentially to approximately $370 per metric ton. Further tightening is expected into Q4 and 2027 due to announced curtailments, project delays, and Indonesian supply uncertainty. Recovering Middle East production and Indonesian smelter ramp-ups are expected to support demand. China remains well-supplied, creating a divergence between tightening ex-China fundamentals and softer conditions within China. Bauxite prices also increased sequentially to $73 per dry metric ton CIF China, driven by higher freight costs.

Aluminum Market Outlook

Aluminum prices moderated but remain supported by constructive fundamentals. Supply is gradually recovering from Middle East restarts and Indonesian ramp-ups, though full recovery timing is uncertain. Global aluminum inventories remain historically low at approximately 42 days of consumption, leaving the market vulnerable to disruptions. Regional premiums (Midwest, Rotterdam, Japan) have moderated but are supported by low inventories and regional deficits, particularly in North America and Europe. Packaging and electrical markets lead demand, transportation is resilient, while European construction remains soft. Customer sentiment is cautious but constructive, with interest in secure supply and long-term agreements.

Capital Allocation and Deleveraging

Alcoa ended Q3 with a strong balance sheet and robust year-to-date free cash flow. The AliGroup acquisition is structured to result in pro forma leverage of approximately 1.5x. Following the acquisition's closing, deleveraging will be the company's priority, utilizing free cash flow, locked box cash from the transaction, proceeds from additional asset sales, and monetization of Ma'aden shares. The company plans to update its adjusted net debt target post-acquisition close, reflecting the combined portfolio's stronger through-cycle cash flow generation.

Western Australia Mine Plan Approvals

The Western Australia EPA's review of Alcoa's mine plan is taking longer than expected, with the process now anticipated to extend into 2027, including appeals and ministerial decisions. Alcoa has incorporated an additional 6 months of mining in current areas into its plans, and approvals by mid-2027 are not expected to materially affect supply, quality, or cost. The company maintains confidence in ultimately securing the approvals and has contingency plans available if needed, including resequencing and modifying mining activities.
