Record Q2, South32 deal, but downgrade and tariffs weigh

Record Q2 results and debt paydown Alcoa posted record Q2 revenue of $4B, EPS of $2.12, EBITDA of $901M, and $608M cash, while paying off its 2028 notes. Strong profits and lower debt support the stock.
This is new positive financial performance that drove sentiment in Q3.
Morgan Stanley downgrade on aluminum surplus Morgan Stanley downgraded Alcoa due to an expected aluminum surplus, cutting 2027–28 price forecasts by 11–13%. Lower expected prices hurt future earnings outlook.
This is a new negative analyst action that pressured the stock in Q3.
Canada's 15% retaliatory tariffs on U.S. aluminum Canada imposed 15% retaliatory tariffs on U.S. aluminum, adding cross-border costs for Alcoa. This raises expenses and could disrupt trade flows between the two countries.
This is a new regulatory/trade headwind that emerged in Q3.
South32 acquisition funded with $2.6B debt Alcoa agreed to buy South32 assets for ~$4.1B, expecting ~$900M synergies, but borrowed $2.6B to fund it. The deal adds growth but also debt and fixed interest obligations.
This is a major strategic move with both positive synergies and negative debt impact, new in Q3.

Alcoa funds South32 buy, adds gallium, tariff fight drags on

U.S. pays Alcoa $174M to build gallium plant in Australia Washington gave Alcoa $174 million to build a gallium plant at its Western Australia refinery, making a semiconductor metal China mostly controls. It is new, non-aluminum revenue tied to defense demand, a small but real plus for Alcoa's long-term earnings.
New government funding for a new product line is a fresh positive driver for AA.
Canada hits U.S. aluminum with retaliatory tariffs Canada put 15% duties on U.S. aluminum, answering America's 50% tariff on Canadian metal. Alcoa sells Canadian-made aluminum into the U.S., so this adds cost and friction to its cross-border trade, a headwind on top of the existing tariff fight.
A new retaliatory tariff directly raises costs for Alcoa's Canadian-to-U.S. flows.
Alcoa borrows $2.6B and closes financing for South32 assets Alcoa raised $2.6 billion in bonds and closed the package funding its roughly $3.1 billion purchase of South32's bauxite, alumina and aluminum assets. It gains scale in raw materials, but adds debt and fixed interest bills that must be paid even if prices or tariffs turn against it.
The debt-funded acquisition is a major new capital event that reshapes Alcoa's balance sheet and risk.
Alcoa says Midwest Premium holds up even if Canada tariffs are halved Alcoa's CFO said the U.S. still needs about 1 million tons of aluminum Canada cannot supply, so the Midwest Premium should not fall sharply if Canadian tariffs are cut. Alcoa recovers over $1 billion in tariffs through that premium and profits from tight supply.
Management's new guidance says a feared tariff cut would not badly hurt Alcoa's pricing.

Alcoa's record quarter and gallium bet offset by surplus-driven downgrade

Morgan Stanley downgrade on aluminum surplus Morgan Stanley cut Alcoa to Equal Weight, warning that new aluminum supply from Indonesia, Saudi Arabia, India and Angola will create a surplus and push prices down. It slashed its 2027-28 aluminum price forecast by 11-13%, a direct hit to Alcoa's future earnings.
This is the main new force pushing AA down: analysts expect oversupply to weaken the aluminum prices Alcoa sells at.
Record Q2 revenue and profit beat Alcoa posted record quarterly revenue of $4 billion, up 24% from the prior quarter, with adjusted earnings of $2.12 per share and $901 million in adjusted EBITDA. It generated $608 million in cash and paid off its remaining 2028 notes, strengthening the balance sheet.
Strong results and cash generation show the business is currently earning well, supporting the stock even as analysts worry about future prices.
South32 asset deal with $900M synergies Alcoa agreed to buy South32's bauxite, alumina and aluminum assets for about $4.1 billion, its largest-ever deal, and expects roughly $900 million in net-present-value synergies plus immediate earnings and cash-flow growth. It also trimmed 2026 alumina output guidance after refinery problems.
The acquisition expands Alcoa's scale and is expected to boost earnings per share right away, a key reason investors see value beyond today's prices.
Gallium plant and Canadian tariff relief Alcoa approved a gallium plant at Wagerup, Australia, backed by the US, Japan and Australia, that could supply 10% of world demand for the semiconductor and defense metal. Separately, a tentative US-Canada deal would halve aluminum tariffs to 25%, helping Alcoa's Canadian output.
Both are new, concrete positives: a higher-value critical-minerals business and lower trade costs on over a million tons of Canadian aluminum.

Alcoa's $4.1B South32 buy and new power deals reshape its future

Long-term power secured for Norwegian smelter Alcoa signed two power deals with Statkraft for 4.8 TWh of electricity through 2031, covering its Lista aluminium plant in Norway. This locks in stable, predictable energy for years, lowering the risk of costly shutdowns and supporting steady production.
It shows Alcoa is securing a key input for its operations, which supports future earnings and reduces uncertainty.
Gas supply deal for Western Australia refineries Woodside will supply 31.1 petajoules of natural gas to Alcoa's Western Australian refineries from 2027 to 2030. This ensures a steady feedstock for alumina production, helping avoid supply disruptions and keeping costs in check.
It secures a critical input for Alcoa's alumina refineries, which is essential for reliable and cost-effective production.
Alcoa to acquire South32's aluminum assets for up to $5.6B Alcoa agreed to buy South32's bauxite, alumina, and aluminum operations for about $4.1 billion upfront plus up to $750 million more if prices rise. The deal adds assets in Australia, Brazil, and South Africa and is expected to create $900 million in synergies. The stock fell on the news as investors weighed the large cash outlay and new shares.
This is the biggest strategic move this period, reshaping Alcoa's portfolio and driving the stock's sharp reaction.
