Confidence legend: ✓ verified-primary (20-F Item 6, GF leadership page, GF press release) · ◐ partial / aggregator · ⚠ inferred / estimate.
This page is the canonical reference for any thesis claim that turns on GFS’s executive bench. The official GF leadership team page at gf.com/about-us/leadership-team/ is the authoritative current-state list; bios are sourced from individual GF leadership profiles, the FY2024 Form 20-F Item 6.A (filed 2025-03-20), and recent GF press releases. Directors who are not concurrent management are listed in ./governance rather than duplicated here.
The headline operating fact is that GFS has had material executive turnover in the 13 months since the 2025-02-05 leadership-transition announcement: Caulfield → Executive Chair, Breen → CEO, Hollister out → Franklin in (CFO), Anderskouv out → vacancy (President / COO). For an analyst, this means the operating bench has refreshed at the top three layers in a short period — the implication is to weight the 2026-Q2 and 2026-Q3 earnings cycles as execution-stress-tests.
Chief Executive Officer
Tim Breen — Chief Executive Officer (since 2025-04-28); Director (since 2018-01)
- Tenure: ~1 year as CEO; ~8 years on the board; ~7 years at GF in operating / executive roles.
- Prior role at GF: Chief Operating Officer 2023 → April 2025; before that, executive roles spanning strategy, business transformation, and finance since joining GF in 2018.
- Board role: Elected to GF’s board January 2018; serves as Strategy & Investment Committee Member.
- Pre-GF career: Senior leadership team member at Mubadala Investment Company (GF’s founding shareholder); Partner at McKinsey & Company in Abu Dhabi.
- Education: Master of Business Administration, London Business School.
- Location: Based in New York. ✓ GF leadership bio — Tim Breen
Key context: Breen’s direct lineage from Mubadala (he was on the Mubadala leadership team before joining GF) makes him a structurally Mubadala-aligned operating leader — the inverse of the typical post-IPO “professional CEO recruited from outside the sponsor” model. This is consistent with GFS’s controlled-company posture, where alignment between the board’s Mubadala bloc and the operating CEO reduces principal-agent friction. The investor-facing implication: Breen’s strategic decisions are likely to track Mubadala’s longer-term semiconductor-strategic-value calculus, which leans toward differentiated-specialty foundry positioning, geographic diversification (US + EU + Singapore), and CHIPS / EU Chips Act funding capture.
Chief Financial Officer
Sam Franklin — Chief Financial Officer (interim 2025-10-27 → permanent 2025-12)
- Tenure: At GF since 2022 in senior finance roles; ~6 months as CFO (interim → permanent).
- Prior role at GF: Senior Vice President of Business Finance, Operations, and Investor Relations.
- Pre-GF career: Senior finance roles at Mubadala Investment Company, MUFG Bank, and Barclays. 18+ years in finance.
- Appointed Interim CFO: 2025-10-27, on the immediate departure of John Hollister (“personal reasons”). ✓ GFS press release — CFO Transition
- Confirmed permanent CFO: ~2025-12 mid-month, following CFO-search process. ◐ StartupNews — GF names Sam Franklin as CFO
Key context: Franklin’s Mubadala alumni background (combined with Breen’s Mubadala alumni background and the multiple Mubadala-affiliated directors on the board) signals a deep operating-and-strategic alignment between GFS senior leadership and the majority shareholder. There is no public indication of independence concerns — Franklin’s CFO-track career through Barclays / MUFG / Mubadala is conventional finance-leader resume building for a $7B revenue specialty foundry — but the concentration of Mubadala-trained leaders in the operating bench is worth flagging as a corporate-cultural fact. ⚠ analyst observation, not a primary-source claim.
John Hollister — Former Chief Financial Officer (2024 to 2025-10-27)
- Tenure: <2 years.
- Departure: Effective immediately 2025-10-27, “personal reasons.” No specific operating-decision or financial-control issue cited in the 6-K filing.
- Q3 2025 earnings: Released shortly after the Hollister departure announcement; financial guidance reaffirmed. ⚠ confirm in 6-K whether internal controls disclosure was flagged.
President & Chief Operating Officer (vacancy)
Niels Anderskouv — Former President & Chief Operating Officer (2025-04-28 to 2026-03-02)
- Resignation announcement: 2026-02-11, in the same 6-K as the Q4’25 / FY25 earnings release; effective date 2026-03-02. Stated reason: “to pursue another professional opportunity.” ✓ StreetInsider — Anderskouv resignation
- Prior role at GF: Chief Business Officer 2023 → April 2025; before joining GF, ~25 years in semiconductor industry, including SVP at Texas Instruments overseeing the Analog Power business.
- Successor: None named. Tim Breen and other members of the executive leadership team are absorbing P/COO responsibilities — i.e., GFS is operating in 2026-Q2 with no #2 operating-leader.
Key context: Anderskouv’s “to pursue another professional opportunity” framing — combined with the press release’s explicit “not due to any dispute or disagreement” language — is the standard executive-departure boilerplate. The substantive fact is that GFS lost its operating #2 just 10 months after he was promoted into the role from CBO; on the same day Q4’25 results were released. The risk-flag is operating-bandwidth strain on Breen: in his first full year as CEO, he is now also operating as effective COO with no announced succession plan. The 6-K language suggests the board considered the absorbed-responsibilities structure preferable to a rapid external-search process. ⚠ analyst inference; will be re-evaluated as 2026-Q2 / Q3 earnings disclose operating-execution metrics.

Senior Vice Presidents — Business Units & Operations
The SVP / business-unit bench is unusually deep relative to peer foundries (POET, LWLG) because GFS is a multi-fab, multi-segment operating company with $6.79B revenue. Key SVPs whose roles feed directly into the photonics thesis:
Kevin Soukup — SVP of Silicon Photonics Business
- Role scope: P&L ownership of the Fotonix silicon-photonics business unit. Leads customer-facing PDK strategy, capacity allocation across Malta + Singapore (post-AMF) sites, and competitive positioning vs Tower / TSMC / Intel-Jabil.
- Strategic centrality: For LWLG / POET / NLM-style photonics-thesis investors, Soukup is the single most operationally important non-CEO leader at GFS because he owns the Fotonix franchise. ⚠ analyst characterization.
Yew Kong Tan — SVP and General Manager, GF APAC Manufacturing & Singapore Site
- Role scope: P&L ownership of the Singapore manufacturing footprint, including the legacy ex-Chartered fabs and (post-Nov 2025) the integration of the AMF site. The AMF integration is one of the year’s major operating priorities and runs through Tan’s organization.
Hui Peng Koh — SVP and General Manager, New York Fab
- Role scope: P&L ownership of Fab 8 (Malta, NY). Functional owner of the CHIPS Act award execution and the Fotonix capacity-expansion build-out at the Malta campus.
Manfred Horstmann — SVP of Global Fab Engineering Services and General Manager, European Fabs
- Role scope: P&L and engineering ownership of the Dresden Module 1 / Module 2 facilities. Functional owner of Project SPRINT — the €1.1B Dresden expansion announced 2025-10-28 with €495M EU Chips Act state-aid backing.
Ken McAvey — SVP and General Manager, Vermont Fab
- Role scope: P&L ownership of Fab 9 (Burlington / Essex Junction, VT), including the GaN-on-Si CHIPS-Act-supported capacity expansion.

- Tom Caulfield (then CEO; FY2024 compensation)
- John Hollister (then CFO; FY2024 compensation)
- Niels Anderskouv (then CBO; FY2024 compensation)

Form 4 Cadence (Post-HFIAA)
Effective 2026-03-18 under the Holding Foreign Insiders Accountable Act, GFS officers / directors / 10%+ holders began filing Section 16(a) reports. The site’s daily-refresh pipeline now captures these via the standard Form 3 / Form 4 / Form 5 ingest path:
- Form 3 (initial holdings): due within 90 days of 2026-03-18 = by 2026-06-16.
- Form 4 (transactions): due within 2 business days of any beneficial-ownership change.
- Form 5 (annual): due 45 days after fiscal year-end (2026-02-15 first deadline).
Already-observed Form 4 transactions:
- Mike Hogan (CBO): 2026-03-18 sale of 1,800 shares at $43.25 + 150-share gift.
- Saam Azar (CLO): pre-2026-04-23 sale of 500 shares at $48.71; 2026-04-23 sale of 500 shares at $59.66.
The Azar sequence shows ~22% appreciation from one Rule 10b5-1 plan tranche to the next, consistent with GFS’s price recovery from the post-secondary-offering pullback. Pattern to monitor in the next refresh: whether C-suite Form 4 transactions cluster pre- or post- the Q1 2026 earnings release (expected May 2026).
