Alcoa (AA) Business Profile

What it does

Alcoa is a vertically integrated aluminum company: it mines bauxite, refines it into alumina, and smelts alumina into aluminum metal. It also casts that metal into shapes customers can use. Bauxite is the raw material for alumina, while alumina is the main raw material for aluminum smelters.

The company sells bauxite and alumina to customers around the world and uses some of its alumina in its own smelters. It also sells primary aluminum as standard metal or as products made in particular shapes and alloys. Customers use those products to make goods for transportation, construction, packaging, electrical and other industrial markets.

Alcoa operates through two segments. Alumina contains its mines and refineries; Aluminum contains its smelters, casting operations and most of its energy assets. Some of its power facilities supply Alcoa’s operations, while others also sell electricity to outside customers.

Alcoa was founded in 1888 and is headquartered in New York City. It became an independent, publicly traded company in 2016. William F. Oplinger is its president and chief executive officer.

How it makes money

Alcoa earns money by selling bauxite, alumina, aluminum products and some electricity. The Alumina segment mines bauxite and refines it into both smelter-grade and non-metallurgical alumina. Its own smelters use a portion of that output; outside customers buy alumina for smelting or for processing into industrial chemicals. Alcoa also sells bauxite to third parties.

Alumina contracts generally use a market-based Alumina Price Index, adjusted through negotiation for factors such as freight, quality, customer location and market conditions. Alcoa also makes fixed-price spot sales. In 2025, its own smelters accounted for approximately 34 percent of total alumina shipments.

The Aluminum segment smelts metal and casts it into commodity-grade ingot and products such as billet, rod and slab. Aluminum contract prices typically combine the London Metal Exchange price, a regional delivery premium and a negotiated product premium reflecting characteristics such as shape and alloy. Contracts range from spot purchases to multiyear supply agreements. Energy assets provide power to Alcoa facilities and external customers.

Alcoa’s sales depend partly on recurring industrial demand and supply relationships, but market prices change. Both aluminum and alumina prices can be volatile and affect operating results. In Q3 2026, Alcoa reported revenue of $3.7 billion, with the change from the previous quarter primarily reflecting lower metal prices.

For Q3 2026, company-wide adjusted EBITDA was $789 million.

Customers and how it sells

Alcoa sells alumina globally to aluminum smelters and to customers that turn non-metallurgical alumina into industrial chemicals. It also uses alumina in its own smelters. Some third-party alumina sales go through traders, and the company sells bauxite to outside customers as well.

Aluminum customers include fabricators making products for transportation, building and construction, packaging, wire and other industrial markets. Alcoa sells metal directly to external customers and traders, using contracts that range from spot purchases to multiyear arrangements. In Q3 2026, the company said packaging and electrical markets continued to lead demand, while construction, particularly in Europe, remained its softest end market.

Through direct and indirect ownership, Alcoa has 25 operating locations across eight countries on five continents. Its facilities are situated primarily in Australia, Brazil, Canada, Iceland, Norway, Spain and the United States. It serves markets in North and South America, Europe, the Middle East, Australia, China and other parts of Asia. Its operations also include an interest in a bauxite mine in Guinea.

Suppliers and costs

Alcoa obtains bauxite from its own resources as well as contracts and mining leases. Its refining process turns bauxite into alumina; smelters then use alumina and electricity to produce aluminum. The company also buys inputs such as natural gas and coal. It generally procures natural gas through competitive bids from producers and independent marketers.

Energy is a component of production costs. In 2025, energy comprised approximately 24 percent of total alumina refining production costs, and electric power comprised approximately 24 percent of primary aluminum production costs. Alcoa generated approximately 11 percent of the power used at its smelters worldwide in 2025 and generally purchased the remainder under long-term arrangements.

Power contracts vary by location, duration and pricing structure. For example, Alcoa’s Québec smelters purchase electricity under contracts with Hydro-Québec, alongside a separate supply arrangement for Baie-Comeau. Alcoa’s Warrick power plant uses coal purchased from third parties. Raw material costs also matter: higher caustic soda and lime prices contributed to unfavorable Alumina segment costs in 2025.

Competitive position

Alcoa competes throughout the aluminum supply chain with bauxite miners, alumina suppliers, commodity traders and aluminum producers. It also faces competition from producers of alternative materials, including steel, copper, composites, plastic and glass.

Rio Tinto and South32 have interests in aluminum-chain assets alongside Alcoa. Rio Tinto is a partner in the Bécancour smelter and the Alumar refinery; South32 has interests in the Alumar refinery, smelter and casthouse. It was reported on 30 October 2026 that Alcoa had agreed to buy South32’s bauxite, alumina and aluminum assets and that South32 shareholders had approved the deal.

Alcoa sells recycled-content and lower-carbon products under its Sustana brand. It also participates in ELYSIS, a venture developing patent-protected smelting technology that eliminates direct greenhouse gas emissions from the traditional process. Development-scale quantities of ELYSIS metal have been sold for commercial uses, while the technology continues toward larger-scale development.

Our reading: Alcoa’s mines, refineries, smelters and energy assets provide an integrated operating position, but commodity-linked pricing and competition across the supply chain limit the protection that integration provides. Our reading: lower-carbon products and ELYSIS offer potential differentiation, although the technology is still being developed for larger-scale commercialization.

Growth opportunities

Alcoa pursues growth projects that build on its existing operations and serve customer demand, including projects developed internally and acquisitions. It evaluates growth spending against other uses of capital, including maintaining assets, reducing debt and returning cash to shareholders.

It was reported on 30 October 2026 that Alcoa had agreed to purchase South32’s bauxite, alumina and aluminum assets and that South32 shareholders had approved the deal. Alcoa expects the acquisition to close in the first half of 2027, subject to required approvals. It completed $2.6 billion of debt financing for the transaction in September 2026 and canceled its bridge facility. Alcoa plans to prioritize reducing debt after closing.

Alcoa has also restarted smelting capacity. In Q3 2026, it reported that the San Ciprián and Brazilian smelter restarts were complete. The company is preparing for mine moves in Western Australia, although it expects the approvals process to extend into 2027.

Separately, ELYSIS is developing technology for aluminum smelting without direct greenhouse gas emissions from the traditional process. Alcoa has a right to purchase a portion of the metal from an industrial-scale demonstration. Alcoa also agreed to sell part of the Messina East site, with potential cash proceeds of up to $315 million, subject to conditions.

Structural risks

• Commodity cycles: Aluminum end markets are cyclical, and aluminum and alumina prices can move substantially. Lower demand or prices, and changes in commodity-linked production costs, can affect results.
• Energy supply and cost: Alcoa relies on third parties for much of its energy. Higher prices, interruptions, or an inability to renew contracts on cost-effective terms can make refineries or smelters uneconomic and lead to curtailments.
• Mining approvals: Alcoa must obtain and maintain permits for mining. Western Australia approvals are taking longer than the company expected; Alcoa expects the process to extend into 2027 and is modifying mining activities as a contingency.
• Global operations and regulation: Operations in multiple countries expose Alcoa to political instability, trade restrictions, tariffs and changes to leases, permits or mining rules. Environmental and other compliance requirements can also increase costs.
• Execution and financing: Portfolio changes, capital projects and developing technologies may incur costs without delivering their anticipated benefits. The planned acquisition adds debt financing, and Alcoa’s access to future financing depends on credit, capital-market and commodity-market conditions.
• Operational disruption: Accidents, environmental incidents, cyberattacks, system failures and labor disputes can interrupt operations or create liabilities. Alcoa reported a fatality at its Brazilian smelter in September 2026.

Bottom line

Our reading

Our reading: Alcoa is an integrated producer whose results depend on both the prices it receives for alumina and aluminum and the cost and reliability of mining, refining, smelting and power. Its assets and customer relationships support a presence across the supply chain, but do not remove commodity or operating risk. The proposed acquisition adds a route to scale while making successful integration and debt reduction important to the business.
