Section role
This section answers who is GlobalFoundries, how did it get here, and who runs it today. GFS sits in a different corporate-form bucket than POET (Ontario FPI) or LWLG (Delaware domestic): it is a Cayman Islands-incorporated, US-headquartered foreign private issuer that files an annual Form 20-F plus interim Form 6-K rather than 10-K / 10-Q. The control structure (Mubadala holds a majority stake even after multiple secondary sell-downs) makes the corporate spine load-bearing for every downstream thesis claim — capacity allocation, related-party agreements, registration-rights mechanics, and the Mubadala-led capital-return cadence (2024 secondary sell-down, 2026 secondary sell-down + buyback) all flow through here.
Read this section first so that the technology / financial / market / thesis sections sit on top of a verified corporate frame.

Filing-regime quick reference
- Domicile: Cayman Islands (parent: GLOBALFOUNDRIES Inc.). Operating headquarters in Malta, NY (Fab 8 site).
- Annual report: Form 20-F (not 10-K). Most recent: filed 2025-03-20, accession 0001709048-25-000024, fiscal year ended 2024-12-31. ✓ SEC EDGAR — GFS 20-F 2025-03-20
- Interim reports: Form 6-K (not 10-Q) with quarterly press release + financial statements furnished.
- Beneficial-owner filings: Mubadala-affiliated entities file Schedule 13D / 13G/A as principal shareholder. Most recent 13G/A reports 423,042,773 shares = 77.05% of outstanding (post the 2026-03-13 secondary). ✓ Schedule 13G/A — Mubadala et al.
- Section 16 / Form 4: Historically NOT applicable to GFS as an FPI. The Holding Foreign Insiders Accountable Act (HFIAA), signed 2025-12-18 and effective 2026-03-18, ends the FPI carve-out from Section 16(a) — GFS officers/directors began filing initial Form 3s by 2026-03-18 and ongoing Form 4s thereafter. ✓ Harvard CorpGov — Section 16(a) Insider Reporting Legislation Ends FPI Exemption (2026-01-18)
- Domestic statutory tax rate: 0.0% at the Cayman parent level; substantive US, EU, Singapore, and Korean tax exposure flows through operating subsidiaries. ⚠ FY2024 20-F Item 5.A — confirm in next refresh.
Note on user-supplied scope brief: The original scope brief described GFS as a “domestic 10-K filer” with Form 4 reporting in effect. The accurate position is: 20-F filer (FPI) with Form 4 only newly applicable post-HFIAA (effective 2026-03-18). This is a meaningful divergence from POET (still FPI; HFIAA also applies to POET on the same effective date) and from LWLG (always domestic, always Form 4). All three KBs converge on Form 4 reporting from 2026-03-18 onward; the historical record before that date differs by issuer type.

Foundry positioning vs peers
GFS is a specialty / differentiated foundry competing in the merchant pure-play tier alongside TSMC, Samsung Foundry, UMC, and SMIC — but its strategic position is structurally different. Following the 2018 7nm pivot, GFS does not compete on bleeding-edge logic (TSMC N3/N2, Samsung 3GAP, Intel 18A); instead it leverages mature-node specialty processes (12LP FinFET, 22FDX FD-SOI, 90WG / 45CLO silicon photonics, RF SOI for handsets, BCD power for automotive). 2025 share: TSMC ~70% of pure-play foundry revenue, Samsung ~7%, SMIC ~5%, UMC ~5%, GFS ~4%. ◐ Counterpoint Research — Q1 2025 foundry share data
For the photonics scope, the load-bearing positioning is: GFS Fotonix is the leading merchant silicon-photonics foundry by revenue post-AMF acquisition (TrendForce, 2025-11-18 — “becoming largest pure-play silicon photonics foundry”). The merchant alternatives are Tower Semiconductor PH18 (200mm, with 300mm migration announced 2024-11-26) and TSMC’s internal SiPh process (largely captive for Nvidia / Marvell / Broadcom hyperscaler customers). Intel’s silicon-photonics business was divested to Jabil in 2024.

Discipline reminder
Every fact in this section must cite a primary source — the most recent Form 20-F (for fiscal-2024, filed 2025-03-20, accession 0001709048-25-000024), a 6-K, the original IPO Form F-1 (filed 2021-10-04, accession 0001193125-21-290644), or a press release on gf.com. GFS has had material recent C-suite turnover (Caulfield → Breen 2025-04-28; Hollister departure 2025-10-27 → Franklin interim → Franklin permanent 2025-12; Anderskouv resignation announced 2026-02-11 effective 2026-03-02), so leadership snapshots have a short half-life — date-stamp every officer claim and re-pull at each refresh.
When a Q&A entry surfaces a new primary-source fact, append it here in the same edit (per the project KB-update-on-validation rule).
