Alcoa (AA) Q3 2026 earnings review

Alcoa's smelters set records, but lower metal prices cut profit

Alcoa's smelters ran better than ever, but a lower aluminum price took back more than the plants delivered. Revenue rose 24% from a year ago, yet profit before depreciation fell 12% from last quarter. Chief executive William Oplinger credited the refineries and smelters; by our math the plan has aluminum output falling next quarter.

At a glance
Revenue$3.7B +24% from a year ago
Operating profit before depreciation, excluding one-offs$789M −$112 million from last quarter
Realized aluminum price$4,527 a tonne −5% from last quarter
Full-year volume outlookUnchanged Q4 smelting profit planned $30M lower before prices

⚖️ Verdict: 🔴 Bearish

The story got worse, because metal prices fell before the South32 deal closes and Alcoa has no spare volume to offset them. The aluminum segment gave up a fifth of its profit, and the fourth-quarter outlook calls for a further decline before any price move. Still, alumina refining returned to break-even and the deal financing is done.

The question now is whether the enlarged company earns enough at a lower aluminum price to carry twice the debt. Either premiums and the alumina recovery hold, or the London price keeps sliding and the interest bill arrives before the extra earnings. The fourth-quarter aluminum segment result will tell.

Alumina Refining Climbs Back to Break-Even

Alcoa's refineries turn bauxite into alumina, the white powder that smelters melt into metal. For three quarters this business lost money, because the alumina it sold fetched less than it cost to make. That changed: the segment lost just $1 million in the third quarter, against $96 million in the spring.

Output at the Pinjarra refinery in Australia recovered after a cyclone and gas disruptions earlier in the year. Alumina production rose 11% from the spring, the company said, "primarily due to improved stability at the Pinjarra, Australia refinery". A higher alumina price helped too, because most third-party alumina sells at the spot index.

  • Realized alumina price: $353 a tonne, up 6% from last quarter
  • Cost per tonne produced and shipped: $354, down 4% from last quarter
  • Segment profit change: +$95 million, against a plan for +$10 million
  • Alumina price index on October 9: $372 a tonne

One quarter at break-even does not settle the risk, but the outlook does more. Alcoa expects fourth-quarter refining performance to "remain consistent with the strong third quarter performance", and the spot index already sits above the cost per tonne. So refining should stop diluting smelting, just as the South32 purchase lifts refining output from 9.1 to 14.2 million tonnes a year.

What to watch: the alumina segment profit for the fourth quarter, due in January. A positive number would confirm the loss-making stretch has ended, because it would arrive while maintenance and raw-material costs are rising.

Smelters Made More Metal for a Sixth Quarter

Alcoa's smelters produced 649,000 tonnes of aluminum, 2% more than in the spring. It was the sixth quarterly increase in a row, after the Alumar smelter in Brazil finished its restart. Five smelters and one refinery set year-to-date output records. Only 66,000 tonnes of smelting capacity remain idle, most of it at Warrick in Indiana.

Better-run plants showed up in costs: lower production costs added $119 million against the spring quarter, the largest positive item in the profit bridge. That covered half of the $235 million lower metal prices took away. Chief executive William Oplinger said Alcoa "increased production across our smelting portfolio" and wants to keep "sustaining operational stability".

What to watch: fourth-quarter aluminum production. By our math the unchanged full-year plan points to about 608,000 tonnes, below this quarter, so a figure near 649,000 would mean the plan was cautious rather than the smelters slowing.

🟢 strengthening CAPITAL ALLOCATION

Alcoa Shows What the South32 Assets Earn

Alcoa agreed in June to buy South32's bauxite, alumina and aluminum interests, a group it calls AliGroup, for $4.1 billion plus a price-linked payment of up to $750 million. Until now it had shown no figures for what it was buying. This quarter the company published a pro forma view for the first half of 2026.

  • Pro forma profit per share: $3.55, against $3.13 for Alcoa alone
  • Pro forma annualized operating profit before depreciation: $4.0 billion, against $3.0 billion alone
  • Implied AliGroup earnings, by our math: about $1.0 billion a year, or about four times the purchase price
  • South32 shareholders approved the deal on October 15; closing still expected in the first half of 2027

At that rate the purchase looks cheap, which supports the slide's claim that the deal is "accretive on pro forma basis". But the first half of 2026 held the highest metal prices in years, so the same assets earn less at today's price. The pro forma figures also exclude integration costs and come from South32's own reports.

What to watch: AliGroup's earnings for the second half of 2026, due when South32 reports in February. A number well below half of the implied $1.0 billion would mean the four-times figure was a peak-price snapshot.

🟢 persistent COMPETITION

Positives This Quarter Didn't Test

Two parts of the case for Alcoa got no new numbers in the release or the slides this quarter, so they stand where they were, neither stronger nor weaker.

  • Supply security as a selling point: the slides repeat that North America and Europe stay short of metal and that the order book is strong, without a volume or price figure; the next regional premium disclosure will show whether customers pay for it.
  • Locked-in inputs: labor agreements to 2030 and power contracts with little spot exposure got no update; the annual report's energy table will show whether that still holds.

🐻 Bear Case

🔴🔴 strengthening GROWTH contradicts narrative

Lower Metal Prices Took $235 Million of Profit

Smelting earns almost all of Alcoa's profit, and its earnings follow the London Metal Exchange (LME) price with a 15-day lag, plus regional premiums. Alcoa's slides describe a market that remains "fundamentally supported". The numbers say the price reversal that was the main risk to the case has started.

  • Realized aluminum price: $4,527 a tonne, down 5% from last quarter
  • Metal prices: −$235 million against the spring quarter, the largest item in the profit bridge
  • Aluminum segment profit: $862 million, down 20% from the spring record
  • LME price on October 9: $3,056 a tonne, with each $100 move worth $237 million a year by the company's sensitivity
  • Shipments: 693,000 tonnes, down 5%, so volume took another $44 million

There is no spare volume to offset a lower price, because the restart programme is nearly done and by our math the unchanged full-year shipment plan points to fewer tonnes in the fourth quarter than in the third. Alcoa also expects raw-material costs and planned maintenance to cost the segment about $30 million more next quarter, before any price change.

The company says "Most value add production remains sold out or operating near capacity", which supports the premium story. But premiums in the Midwest, Rotterdam and Japan "eased sequentially from elevated levels" anyway, so the premium cushion is thinning at the same time as the base price.

What to watch: the realized aluminum price for the fourth quarter. A drop larger than this quarter's would mean the record spring quarter was the top of the cycle, with the acquisition and its interest bill still ahead.

Debt Doubled Before the Deal Closes

To pay the cash portion of the AliGroup price, Alcoa sold $2.6 billion of notes in September at interest rates of 6.625% and 6.875%. Total debt rose to $4.8 billion from $2.2 billion three months earlier, while the cash sits idle until closing, expected in the first half of 2027.

  • Annual coupon on the new notes, by our math: about $175 million
  • Full-year interest expense outlook: about $185 million, up from about $135 million at the start of the year
  • Fourth-quarter interest expense implied by the full-year outlook: about $79 million, against $42 million this quarter
  • Partial offset: about $20 million more interest income on the cash pile in the fourth quarter
  • Leverage after the deal: 1.5 times on a pro forma basis, the slides say

The interest bill arrives now and the acquired earnings arrive after closing, and the gap widens if metal prices keep falling. Chief executive William Oplinger told investors in July that a 5% annual fee on the cash consideration starts once South32 shareholders approve, which they did on October 15. So carrying the deal costs money through at least two more quarters.

What to watch: the updated adjusted net debt target Alcoa has promised for closing. A target well above the current $1.0 to $1.5 billion range would mean the balance sheet stays stretched through the next price cycle.

🔴 persistent DISCLOSURE

Risks This Quarter Didn't Answer

Four standing concerns got no new numbers in the release or the slides, and each still bears on what the enlarged company will earn once the South32 assets arrive next year.

  • Western Australia mine approvals: the slides say only that environmental assessments continue; the quarterly filing's mine-approvals section will show whether the end-2026 ministerial decision still stands.
  • Power contracts tied to the metal price: in July the filing expected $376 million of losses to run through sales over twelve months; the amount booked this quarter is not in the release.
  • San Ciprián in Spain: the refinery still has 800,000 of its 1.6 million tonnes of capacity idle, and cash use at the site was not disclosed.
  • Tariffs and premiums: the plan called for tariff costs on Canadian metal to fall $10 million this quarter; the release does not say where they landed.

Massena East Sale Signed for Up to $315 Million

Alcoa signed definitive agreements to sell parts of its closed Massena East site in New York for data-center development. It expects $50 million to $65 million at closing, due within six months. Up to $250 million more can follow over seven years as the buyer commissions approved capacity. The company said the deal "creates the potential for meaningful cash proceeds" and counts it as the first toward its $0.5 billion to $1 billion site-sale target.

Alumina Market Tightens While Aluminum Softens

Alcoa's two markets moved in opposite directions. The alumina price index rose to $372 a tonne by early October, which the company attributed to expected curtailments outside China and recovering demand from Middle East smelter restarts. Over the same period the LME aluminum price fell to $3,056, while global inventories stood at about 42 days of consumption, a level the slides call a historical low "limiting the market's ability to absorb further supply disruptions".

💲 Other KPIs

Free cash flow (26Q3) $472 million
⇗ accelerating

Cash from operations was $643 million and free cash flow $472 million, the second strong quarter in a row after an outflow in the first quarter. Year-to-date free cash flow stands at $596 million, already more than all of 2025. Capital spending of $171 million ran inside the full-year plan of about $750 million.

Adjusted net debt (26Q3) $969 million
⇘ decelerating

Adjusted net debt, which is debt less cash plus pension and retiree obligations, fell to $969 million from $1.45 billion three months earlier, below Alcoa's $1.0 to $1.5 billion target. The fall comes from cash generation, not repayment: borrowing more than doubled and the proceeds sit in cash until the acquisition closes.

Days working capital (26Q3) 50 days
⇒ stable

Working capital tied up 50 days of sales, four more than in the spring and the same as a year ago. Inventories rose to $2.6 billion, up 17% from a year ago, because the smelters now hold more metal, while receivables fell with lower sales.

🔮 Guidance

FY26 Alumina production 9.5–9.6 million metric tons
🠆 unchanged from 9.5–9.6 million metric tons
⇒ stable

Unchanged. The plan still calls for a small rise in refinery output this year. By our math it leaves 2.46 to 2.56 million tonnes for the fourth quarter, about 2% above the third quarter at the middle of the range. That looks reachable, because the third quarter already matched the pace the plan requires.

FY26 Alumina shipments 11.5–11.6 million metric tons
🠆 unchanged from 11.5–11.6 million metric tons
⇒ stable

Unchanged. Shipments include traded and externally sourced tonnes, which carry no refining margin. By our math the fourth quarter needs 2.98 to 3.08 million tonnes, roughly the third quarter's level, so the year rests on holding output rather than raising it.

FY26 Aluminum production 2.4–2.6 million metric tons
🠆 unchanged from 2.4–2.6 million metric tons
⇘ decelerating

Unchanged. Nine-month output of 1.9 million tonnes already covers most of the range. By our math the middle of the range leaves about 608,000 tonnes for the fourth quarter, below the 649,000 just produced, even though Alcoa expects higher output in both segments. Either the plan is cautious or the year lands near the top of the range.

FY26 Aluminum shipments 2.6–2.8 million metric tons
🠆 unchanged from 2.6–2.8 million metric tons
⇘ decelerating

Unchanged. By our math the fourth quarter needs 568,000 to 768,000 tonnes, and the middle of that range sits below this quarter's 693,000. Lower shipments are the volume term in a quarter where the price term is also moving down.

Q4 Alumina segment profit, change from Q3 Consistent with Q3, before index prices and currency
⇒ stable

New. Alcoa expects refining performance to hold at the third-quarter level before index prices and currency. Because about 95% of third-party alumina sells at the spot index, each $10 a tonne adds about $91 million a year by the company's sensitivity. The index reached $372 in early October against a realized $353 in the quarter.

Q4 Aluminum segment profit, change from Q3 About $30 million unfavorable, before index prices and currency
⇘ decelerating

New. Alcoa expects "higher raw material costs and planned maintenance intended to support continued operational stability" to cut smelting profit by about $30 million from the third quarter, before any metal price change. The third quarter beat its own flat plan on the same basis by about $37 million by our math, so the fourth quarter starts from a higher base than planned.

Q4 Alumina costs within the Aluminum segment About $30 million unfavorable
⇘ decelerating

New. Smelters buy alumina at index prices on a six-to-eight-month average, so the higher alumina price now flows into smelting costs. The company adds that each $10 a tonne rise in the index removes $7 million to $9 million through intersegment profit elimination. This is the cost side of the alumina recovery.

Q4 Other income About $20 million favorable
⇗ accelerating

New. Interest earned on the $4.4 billion of cash held for the acquisition lifts other income by about $20 million. By our math that covers roughly half of the extra interest expense the new notes add each quarter.

FY26 Interest expense About $185 million
🠅 raised from About $135 million
⇗ accelerating

Raised. The year's interest bill rises by about $50 million because of the $2.6 billion of notes sold in September. By our math that leaves about $79 million for the fourth quarter, nearly double the $42 million just booked, and the run rate stays until the acquired assets contribute after closing.

Q4 Operational tax expense $65–75 million
⇘ decelerating

New. Lower than the $85 million booked this quarter, because Alcoa expects lower prices and a different mix of countries where it earns profit. The third quarter landed at the middle of its $80 to $90 million range; the quarter before landed at the bottom.

FY26 Depreciation, depletion and amortization About $680 million
🠅 raised from About $660 million
⇒ stable

Raised. Depreciation rises another $20 million, after a $30 million increase in July that the company attributed to currency and changes in asset lives. By our math the fourth quarter carries about $169 million, slightly below the $176 million just booked.

❓ Key Questions

What does AliGroup earn at today's aluminum price?

The pro forma figures cover the first half of 2026, when the realized price peaked. Alcoa has not said what the assets earn at an LME price near $3,000, or which price its 1.5 times leverage figure assumes.

How much power-contract loss ran through sales this quarter?

In July the filing expected $376 million of losses from metal-linked power contracts to hit sales over twelve months. The release shows only a $32 million mark-to-market gain as a special item, leaving the realized amount unreported.

Is the Western Australia mine approval still due this year?

Approval for the Myara North and Holyoake mine regions has slipped before, and the slides say only that assessments continue. A slip past mid-2027 would force changes to mining and refinery rates, by Alcoa's own earlier account.

What will the new net debt target be after closing?

Alcoa says it will update the $1.0 to $1.5 billion adjusted net debt target at closing to reflect "stronger through-cycle cash flow generation". A higher target changes how much pro forma profit goes to debt reduction.

What LME price does the fourth-quarter outlook assume?

The $30 million smelting headwind and the flat refining outlook exclude index prices and currency. The LME fell to $3,056 by October 9, and each $100 a tonne moves annual profit by $237 million.
