GlobalFoundries (Nasdaq: GFS) is the world's largest fully independent semiconductor foundry by revenue outside of TSMC and Samsung.
Group exposure score is 77 including 2 tracked subsidiary — standalone is 75.
Named counterparties identified by open-source research and written only where a primary source states the relationship — never inferred from sector or co-mention. 11 suppliers, 5 customer-side. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.
Wafer Supply Agreement; GF's spin-off parent. The amended WSA gave AMD full flexibility to buy at 7nm or beyond from any foundry, with committed pricing/volume at 12nm through 2019-2021 — a named customer whose lock-in was contractually loosened.
Exclusive-supplier agreement announced Feb 2023 for US-produced chips as GM shifts to EVs. Volume and value undisclosed.
10-year contract with a $3.1bn spending ceiling, announced Sept 2023. A ceiling is not a committed spend. Ties directly to the Malta NY Trusted Foundry / DHS-designated status.
GF anonymises its >10% customers in the 20-F, so the audited figure is disclosable but the identity is not. `single-vintage-only` because nothing in the filing binds the letter A to the same entity across filings — the FY2023 17.0% / FY2024 15.7% series is carried in prose and must NOT be joined to this row as one counterparty. Do not map A onto the AMD/GM/DoD list above; the disclosure deliberately withholds that mapping.
Second >10% customer in FY2025, crossing the threshold from <10% in FY2023 and FY2024. Same identity caveat as Customer A: the letter is defined inside one filing only, so this is a size claim, not an entity claim.
Single-supplier share of all SOI wafers. GF states it is 'in the process of developing relationships with alternate suppliers' but does 'not expect to be able to acquire a significant amount of SOI wafers from those suppliers in the near term'. $68m net due to this supplier at 2025 year-end vs $9m at 2024.
Prior vintage. The multi-vintage delta is the finding — dependence rose ~10pp in one year while the mitigation sentence stayed on the page.
Earliest disclosed vintage. Only a limited number of companies worldwide can produce SOI wafers at all, so this is a genuine chokepoint, not a procurement preference.
Named principal silicon-wafer supplier in the FY2024 20-F (filed 2025-03-20), one of only three still named that year. Named in FY2022 and FY2023 as well. No share disclosed. The 20-F names neither the S.E.H. wafer plant (Japan, US, Malaysia, Taiwan) nor the receiving GF fab (US, Germany, Singapore), so no route can be pinned; JP>US is not evidenced.
New to the FY2024 named list, replacing GlobalWafers Singapore Pte. Ltd. MEMC is GlobalWafers' US subsidiary at St. Peters, Missouri — read as a Singapore-entity to US-entity shift on one corporate parent (an onshoring signal), which is interpretation, not GF's own statement.
Named principal wafer supplier in the FY2022 and FY2023 20-Fs; absent from FY2024 onward. No share disclosed.
Named principal wafer supplier in FY2022/FY2023, dropped from the FY2024 list. GF does not say whether this is consolidation or a drafting change — do not present either read as GF's.
Named principal wafer supplier in FY2022/FY2023, dropped from the FY2024 list.
Named principal wafer supplier in FY2022/FY2023, dropped from the FY2024 list. In the FY2025 20-F the supplier-naming sentence was removed entirely — six named suppliers to three to none across four vintages.
High-purity industrial gases under a renewed 15-year partnership at Malta, New York, plus a new Singapore plant supplying high-purity nitrogen from 2026; over EUR 50m across both. Announced 2024-02-19 by Air Liquide. Re-checked 2026-09-27 (wake-minerals-buyers, step 0.5): press release still live verbatim, no retraction or superseding announcement found. An existing Dresden cooperation is referenced with no terms disclosed. This is the named counterparty behind the helium/process-gas exposure.
Multi-year photomask supply agreement (Aug 2019) under which Toppan acquired GF's Burlington, VT photomask facility. Photomasks are a physical fab input, so unlike the licensing partners this is a genuine supply relationship.
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.
Another tracked dossier names 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: 990 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.
GF FY2025 20-F: 'If we are unable to obtain 300mm SOI wafers from Soitec S.A. (Soitec), our primary supplier ... In 2025, Soitec accounted for approximately 71% of our SOI wafer spend' (61% in 2024). Exhibit 4.13, 2024-2025 Mixed Product Addendum effective 2024-10-09, between GlobalFoundries U.S. Inc. (Malta, NY) and Soitec S.A. (Bernin, FR), with Soitec Microelectronics Singapore Pte. Ltd (Pasir Ris, SG) also supplying as part of the Supplier Group; separate purchase addenda cover GF Dresden. The filings do not say which Soitec plant ships to which GF fab, so the route is not pinned. Volumes and prices redacted.
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.
Every exposure is read as a buyer dependency; the top 3 are its binding chokepoints.
As a buyer, policy pressure across its consumed materials is rising.
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.
