Aluminum earnings point to risk, not disruption

First-quarter earnings are beginning to provide some clarity.

Across results from Alcoa, Rio Tinto, Kaiser Aluminum and Steel Dynamics, there is little evidence of direct operational disruption. Production has been broadly stable. Shipments have increased modestly.

It would be more dramatic to say operations have been upended, but so far the data does not support that view. These results are now nearly a month old, though recent commentary from executives during earnings calls in the past several days has pointed in the same direction.

From a US standpoint, that consistency is not entirely surprising. The same concentrated supply chain that has limited sourcing flexibility for years has also provided a degree of insulation, even as other regions may be experiencing a different set of conditions.

Primary aluminum

Alcoa reported higher aluminum production and shipments year over year. Rio Tinto’s output followed a similar pattern. Neither company indicated meaningful aluminum constraints tied to the Middle East, although alumina supply is a separate issue.

At the same time, Rio Tinto’s share of production from its Matalco joint venture declined year over year, suggesting recycled billet supply did not increase during the period. That detail becomes more relevant when viewed alongside broader market expectations for substitution.

Preempting exposure

Producers have started to quantify exposure to value-added products in more detail. Alcoa broke out the share of Middle East-origin imports into North America by billet, primary foundry alloy, rod, and slab, and pointed to increased customer outreach.

That breakdown shows a clear split between North America and Europe. In North America, imports are weighted toward billet, which accounted for 55% of value-added product imports from the region in 2025, followed by primary foundry alloy at 32%. In Europe, the mix is more evenly distributed, with billet at 39% and both slab and primary foundry alloy at 27%.

At the same time, Alcoa referenced increased customer outreach and spot order requests but did not explicitly link those inquiries to value-added products. Given Western Europe’s smaller P1020 ingot production base and greater reliance on primary aluminum imports compared with North America, a more cautious reading is at least some of those inquiries may be tied to primary metal, while the extent to which they are directed toward value-added products remains unclear.

Even so, the underlying data makes it harder to identify where a material imbalance has emerged.

Western Europe shows greater reliance on imported slab despite a larger domestic production base. In billet, the picture is more mixed. Western Europe is expected to produce more than twice the volume of primary billet as North America in 2026, according to CRU estimates, while North America holds a larger secondary billet capacity base by nearly 700,000 metric tons.

While that secondary system provides some flexibility substitution is not universal across end markets. It tends to be more feasible in automotive and building and construction applications, wherever alloy tolerances are broader, but remains limited in more tightly specified uses.

Rio Tinto reported lower secondary billet production at its Matalco joint ventures. Steel Dynamics’ nonferrous scrap shipments declined, suggesting weaker demand and reduced feedstock pull across the secondary system. That does not point to an increase in secondary billet output in the US. There will be little indication of any meaningful change until Norsk Hydro reports its results.

Semi-fabricated products

Further downstream, results show variation across product categories rather than a uniform response.

Kaiser reported higher shipments in aerospace and packaging, following subdued output tied to a coating line upgrade at its Warrick facility in prior periods. Meanwhile, general engineering products increased at a slower pace, while automotive extrusion shipments declined year over year.

Kaiser’s general engineering segment includes plate, rod and bar, and extruded products, while its automotive extrusion segment consists of extruded components. Together, these offerings rely on both slab and billet as feedstock.

General engineering and automotive extrusion products provide a clearer test case. Both rely, at least in part, on billet and slab, and include applications where substitution is more feasible. At the same time, North America is less exposed to Middle East slab imports than Europe and maintains a sizable secondary billet base. Even so, those segments did not show a meaningful acceleration in demand.

By contrast, aerospace and packaging shipments increased, though part of that reflects recent facility upgrades and a ramp in aircraft production. In aerospace, where substitution is limited and material specifications are tight, the US remains highly dependent on imported high-purity aluminum, with about 97% sourced from the United Arab Emirates in 2025. That concentration suggests that if a disruption were beginning to affect supply, it would likely show up in this segment or be noted in company commentary.

Process of elimination

Narrowing the focus on value-added products further, primary foundry alloys emerge as one of the more plausible areas of exposure.

North America does not produce a large share of global foundry alloy output, and US production remains limited, largely confined to Century Aluminum’s Mt. Holly facility, which is in the process of ramping previously idled capacity.

At the same time, the Middle East represents one of the largest producing regions outside of Asia, while Western Europe maintains a larger primary foundry alloy base than North America. In applications where substitution is limited, such as aerospace castings and safety-critical automotive components, that imbalance leaves North America more exposed to imported supply.

Secondary alloys provide a partial offset. The US has one of the largest secondary alloy capacity bases globally, following China. However, that flexibility is not universal across end uses.

Where substitution is not feasible, the US remains heavily reliant on imported primary foundry alloy. Even so, recent trade data suggests imports of primary foundry alloy into the US remain modest relative to global production.

Canada accounted for 68% of primary foundry alloy imports in 2025. Those volumes were around half of Canada’s output that year, according to CRU Group data. Even when combined with Middle East-origin supply, total imports barely exceed 50% of Canada’s anticipated output for 2026, which itself represents a relatively small share of global primary foundry alloy production.

In that context, primary foundry alloys may represent a point of US exposure within the value-added market, but not one that has yet translated into a clear supply constraint in the data.

Final thoughts

The earnings results do not point to a market under strain. Instead, they point to a market identifying where strain could emerge.

Billet remains the most visible point of exposure in the US. Primary foundry alloys present a more limited risk. Yet neither has translated into a clear supply disruption for now.

In other words, it seems as though the market is reacting to the possibility of disruption faster than the physical system is confirming it.
