Source: SEC Financial Statement Data Sets, quarterly period, tagged by the issuer. Segment names are the company’s own labels and are not comparable with another filer’s. Shares are of consolidated revenue and need not sum to 100%: overlapping cuts are reported, and segment×geography cross-tabs are dropped rather than counted twice.
GLEIF has an ISSUED LEI record for Alcoa Corporation but reports no parent (parent_reported: false) — the company has not filed optional relationship data, which for a US public company of this size means no filed parent, not necessarily independence, so a web check was done. Aggregated institutional-ownership data (Nasdaq/WallStreetZen/fintel) shows ~75-84% institutional ownership spread across ~1,280 institutions, with the top 15 holders combined at ~51% and no single holder above ~12% — consistent with a widely-held public company, not a controlled one. No majority/controlling shareholder found.
Named counterparties identified by open-source research and written only where a primary source states the relationship — never inferred from sector or co-mention. 4 customer-side. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.

Alcoa press release: 8-year smelter-grade alumina supply agreement from Western Australia, up to 15.6 million tonnes total volume; release states this makes Alcoa EGA's largest third-party alumina supplier. No % share of Alcoa's total alumina sales disclosed.

Scope. Absence of a counterparty here is not evidence that none exists — most commercial sourcing is confidential and never becomes public. Rows without a share figure mean no share was disclosed, not that the relationship is small.
3 other tracked dossiers name this company as a counterparty in its own sourced disclosure — this platform never wrote these rows on this company's own page, they are read here inverted from the dossier that disclosed them. This is a partial view: 1008 additional named-counterparty rows across the corpus could not be matched to a tracked dossier by name at all (mostly non-Latin legal names), so the true count is higher than what renders here.
Alcoa 10-K: 'The amount of bauxite Alcoa purchases from its minority-owned joint venture, Compagnie des Bauxites de Guinée (CBG), differs from its proportional equity in the mine.' Alcoa holds 45% of Halco (Mining) Inc., which owns CBG's 51% shareholder (Rio Tinto operations page), so the offtake is related-party. The 10-K gives no refinery-level destination for the CBG tonnage.
Marubeni's own page: Marubeni Aluminium Australia 'Has 67,000 tpa equity aluminium ingot from Portland Aluminium smelters ... All ingots are exported to mainly Japan and Asian countries.' Portland smelter (Victoria, AU) is 55% Alcoa (operator) / 22.5% CITIC / 22.5% MAA. Equity-linked offtake, not a stake alone: MAA lifts its share of metal. Origin AU (Portland, VIC); destination 'mainly Japan' per Marubeni, so AU>JP is the stated principal flow, some tonnage goes to other Asian countries.
Nexans press release (2024-02-01): low-carbon primary aluminium incl. ELYSIS-process metal for several Nexans facilities in Western Europe and Scandinavia; duration, volume and share_pct not disclosed. Re-checked 2026-09-29: the release names no Alcoa smelter or origin country (ELYSIS metal is R&D-scale; EcoLum is produced at several Alcoa smelters) and names destination only as Western Europe and Scandinavia, so the route is recorded as unstated rather than guessed from Alcoa's US HQ.
Scope. This section is inverted evidence: each linked dossier wrote the original row about itself, describing its own relationship to this company. It is never a claim this company itself disclosed. Absence here is not evidence of no relationship — most of the corpus has no named-counterparty block at all yet.
This company sits on the supply side for 2 of its 2 materials — a restriction on those is a tailwind, not a headwind.
As a producer, policy pressure across its produced materials is flat.
Descriptive trend in official policy actions on this company’s materials — a policy-pressure trend, not a price or trading signal. No forward probability is implied. Direction is measured on actions we have discovered, and discovery lags events: where the recent window is too thin to support a calm reading, the row says coverage-limited instead of easing.
No actions in the register have named or swept this company in the last 24 months.
