Century Aluminum Company (CENX)

Century is Alcoa's closest listed US pure-play primary-aluminum smelter: both sell primary metal priced off the LME plus the Midwest premium, both benefit from Section 232 import tariffs, and Century's new-smelter ambitions (an Oklahoma project with EGA) and Mt. Holly restart directly expand the domestic smelting capacity Alcoa also operates in.

Century's stated US market position and the scale of its planned 750,000-tonne Oklahoma smelter (a joint venture with Emirates Global Aluminium), measured against total US aluminum production.

Jesse Gary (President and Chief Executive Officer): At 750,000 metric tons, the new smelter will more than double total U.S. aluminum production and will restore domestic production of military-grade high-purity aluminum. […] No company is investing more to restore U.S. aluminum production than Century. Century is already the largest producer of aluminum in the United States, employing more American primary aluminum workers than any other company.

On its Q2 2025 call, Century frames a planned new US smelter and its Mt. Holly restart as large additions to domestic primary-aluminum capacity enabled by US trade policy.

Jesse Gary (President and Chief Executive Officer): It will represent the first new smelter built in the U.S. in 50 years and will double the size of the existing U.S. industry, creating over 1,000 fulltime direct jobs and over 5,500 construction jobs. […] we are very pleased to announce today that we've made the decision to restart the last 50,000 metric tonnes of capacity at Mt. Holly and return the plant to full production. […] Century's Mt. Holly expansion will increase total U.S. primary aluminum production by nearly 10%, replacing imported metal.

Century's FY2025 annual report describes the Section 232 aluminum-tariff regime and its February 2025 escalation to 25% with all country exemptions ended — the same import-tariff structure that shapes Alcoa's US metal pricing.

In March 2018, the U.S. implemented a 10% tariff on imported primary aluminum products into the U.S. These tariffs are intended to protect U.S. national security and incentivize primary aluminum production in the U.S., reducing reliance on imports and ensuring that domestic producers, like Century, can supply all the aluminum necessary for critical industries and national defense. […] All imports that directly compete with our products are covered by the tariff. In February 2025, President Trump issued a new Presidential Proclamation directing the tariff rate on imported primary aluminum to be increased from 10% to 25% and for all existing country exemptions or product exclusion to be ended, in each case effective March 12, 2025.

Norsk Hydro ASA (NHY)

Norsk Hydro spans the same value chain as Alcoa — bauxite mining, alumina refining, primary-aluminum smelting, recycling and captive renewable power — and competes directly in alumina supply, primary metal, and low-carbon/recycled aluminum products; its own shareholder-return peer group names Alcoa.

Hydro's stated position in primary aluminum — the ex-China sixth-largest producer with about 2.1 million tonnes of annual capacity — the segment that competes head-on with Alcoa's Aluminum business.

Hydro Aluminium Metal is the world's (excluding China) sixth largest producer and supplier of primary aluminium and value added casthouse products. […] Hydro's total annual primary aluminium capacity is about 2.1 million tonnes.

Hydro's stated view of the 2025 alumina market: a rebalancing (production growth of 3.1% against demand growth of 1.8%) and a Platts alumina index falling from USD 672 to USD 306 per tonne — the shared alumina market Alcoa also sells into.

Following very tight alumina markets and all time high nominal prices in 2024, the global metallurgical alumina market rebalanced in 2025: production growth of 3.1 percent exceeded demand growth of 1.8 percent, driving prices lower throughout the year. The Platts alumina price index started the year at USD 672 per mt and decreased throughout the year, ending the year at the annual low of USD 306 per mt.

Rio Tinto (RIO)

Rio Tinto's Aluminium division is a vertically integrated bauxite, alumina and primary-aluminium producer competing directly with Alcoa across the same value chain — and the two co-own the ELYSIS inert-anode smelting joint venture, making Rio simultaneously a rival and a partner in low-carbon aluminum.

Rio Tinto describes ELYSIS — its inert-anode, zero-direct-emissions smelting joint venture with Alcoa — and a 2024 decision to build a 10-pot, 2,500-tonne-per-year demonstration plant at its Arvida smelter.

Our ELYSIS joint venture with Alcoa is progressing the development of a breakthrough inert anode technology that eliminates all direct greenhouse gas (GHG) emissions from the aluminium smelting process. In 2024, we announced […] a demonstration plant equipped with 10 ELYSIS pots at our Arvida smelter. […] The demonstration plant will have the capacity to produce up to 2,500 tonnes of aluminium per year, with first production targeted by 2027.

Rio Tinto reports a 61% rise in its Aluminium segment's 2024 underlying EBITDA (a 30% margin) and cites record bauxite output at Gove and Amrun, sizing the integrated bauxite-alumina-aluminium business that overlaps Alcoa's.

Overall we delivered a significant uplift in profitability for our Aluminium business with a 61% increase in underlying EBITDA […] underlying EBITDA margin rising nine percentage points to 30% and underlying ROCE of 10%. […] Higher bauxite volumes from record annual production at Gove and Amrun and increased bauxite pricing were partially offset by lower alumina production following the breakage of a third-party gas pipeline in Queensland.

Rio Tinto's self-description as a "global leader in low-carbon aluminium" and its sizing of aluminium demand drivers — a market-framing claim that overlaps Alcoa's own low-carbon positioning (Rio's own framing).

As a global leader in low-carbon aluminium, we are uniquely positioned to further decarbonise our business and support the world's transition towards a lower carbon footprint. […] World semi-fabricated demand rose 2% year-on-year. Primary aluminium demand increased at a similar rate. […] Global aluminium demand will continue to be driven by the energy transition, particularly electric vehicles, and renewable energy.
