Primary filings index — GlobalFoundries Inc. (CIK 0001709048)
This file is the chronological index of GFS SEC filings to cite from. GFS is a US-domestic-issuer Cayman-incorporated, US-domiciled (Malta, NY) Section-12 filer, which means the full domestic-issuer disclosure regime applies:
- 10-K annual report (typically filed mid-Feb following fiscal-year-end Dec 31)
- 10-Q quarterly report (typically filed within 40 days of fiscal-quarter-end)
- 8-K current report (material-event, filed within 4 business days)
- DEF 14A annual proxy statement (typically filed Apr-May, ~30-45 days before AGM)
- Schedule 13D/G beneficial-ownership filings (Mubadala-related entities)
- Form 4 insider-transaction reports (Section 16 applies — every officer + director + 10%+ holder must file)
- Form 144 notice of proposed sale (precedes Form 4 sales)
- S-1 / S-3 registration statements
- 424B5 / 424B7 prospectus supplements (used for shelf take-downs + secondary offerings)
- NT 10-K / NT 10-Q notification of late filing (none on record)
Compare to POET (foreign private issuer, 20-F annual + 6-K interim only, no Form 4) — GFS gives the analyst much more disclosure cadence to work with.

edgar_recent.json ✓ shows three SC 13G filings on dates 2017-06-12, 2022-02-11, 2023-02-09 — these are pre-2024 baseline filings not material to the current Mubadala-stake math, but useful for the historical-cadence reconstruction.
IPO + secondary registration statements
| Filing | Date | Accession # | URL | Notes |
|---|---|---|---|---|
| S-1 (initial IPO prospectus) | Sep 28 2021 | ⚠ to be verified | https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=0001709048&type=S-1 | Initial IPO registration.

Form 4 insider-transaction filings (Section 16)
GFS is a US-domestic issuer; Section 16 applies; every officer + director + 10%-or-more-holder files Form 4 within 2 business days of any transaction.
edgar_recent.json ✓ shows 13+ Form 4 filings between 2026-03-20 and 2026-04-27 — a high cadence consistent with mechanical 10b5-1 plan execution following the post-Q4-2025-earnings open window. Specific filings include:
Verifying which insider filed each Form 4 + the transaction code (S = sale, M = exercise-and-sale, A = grant, etc.) + 10b5-1 plan-flag is the next step in primary-source-validating the risks K5 thesis. This work is deferred to a future refresh cycle.
Earlier pre-public filings (2009-2021)
GFS spun out of AMD in 2009 but did not file SEC EDGAR materials until the IPO registration in 2021. The AMD historical record (10-K commentary on the GF spin-out) is potentially useful for company-history context but is not material to the forward thesis.
Filing-cadence calendar (forward-looking 12 months)

| May 5 2026 | Q1 2026 10-Q + 8-K (Item 2.02 earnings results) |

Notes on filing-data verification
This index marks many specific accession numbers as ⚠ to be verified. The primary-filings-index is intentionally conservative: rather than guess accession numbers from filing-date patterns, the analyst has flagged each accession that has not been directly opened and verified. A future refresh-cycle pass should:
- Open each 10-K, 10-Q, DEF 14A, 8-K, and SC 13G material filing on EDGAR via the company-CIK browse interface
- Record the accession number + URL + key disclosure quote
- Update this index with the verified data
- Cross-reference each accession to specific bull/bear-case pillar citations
Until that work is done, the existing primary-source citations in the thesis files defer to corporate-press-release primary sources (which are themselves primary, but lower-density than the underlying 10-K / 10-Q financial-statement data they reference).
