2026-09-21 — GlobalFoundries and SMART Photonics launch an open-access foundry service combining silicon and indium-phosphide photonics

• GlobalFoundries and Dutch chipmaker SMART Photonics launched what they call the industry’s first commercial open-access foundry service combining silicon photonics with indium-phosphide lasers, modulators and amplifiers, targeting AI data centers, optical transceivers and lidar, with general availability planned for the second half of 2027. The active indium-phosphide parts are flip-chip mounted into cavities in GlobalFoundries’ silicon photonics chips after more than a year of joint engineering, so designers get both technologies through a foundry rather than building the integration themselves. It adds a customer-facing product to the silicon-photonics strand this thread tracks through the $300M photonics CHIPS award and the Marvell optical-capacity expansion. (Bits&Chips)

2026-09-17 — Marvell deal expands, and Japan floats GF as operator of a new US chip plant

• GlobalFoundries and Marvell Technology expanded their multi-year manufacturing agreement to increase capacity for silicon-germanium (SiGe) chips used in high-speed AI-data-center optical connections, at GlobalFoundries’ Burlington, Vermont fab. The expanded deal is meant to meet Marvell’s demand for advanced optical-networking products — pluggable optical transceivers, near-packaged and co-packaged optics — driven by AI data centers’ growing data-volume needs. GlobalFoundries shares rose about 4% and Marvell about 6.3% the same session. (Reuters via Yahoo Finance)
• Separately, Japan and the US are in working-level talks for GlobalFoundries to operate a new US logic-chip plant, funded as part of Japan’s $550 billion tariff-linked investment pledge to Washington — the first time that pledge has been directed at semiconductor manufacturing rather than the energy and industrial-materials projects announced so far. The project is estimated at 2-3 trillion yen (roughly $12.8-19.3 billion); officials are still discussing how the investment would be recouped. Talks were held 2026-09-14/15 and first reported 2026-09-17. (Yahoo Finance/Benzinga, citing Nikkei)

2026-09-08 — $375m Commerce Department award finalised, but for quantum tech, not AI silicon

• GlobalFoundries finalised a $375m Commerce Department award for quantum technology. Adjacent to this thread rather than inside it — quantum hardware, not AI silicon — but it is the same industrial-policy instrument (a direct federal award) this thread already tracks on the AI-capex side, now pointed at a different technology. ⚠️ No source link located for this item; recorded from the digest text alone.

2026-08-10 — GlobalFoundries hands its factory data to Redpanda to run AI agents across every fab

• GlobalFoundries selected Redpanda’s streaming-data platform to unify real-time manufacturing, engineering, supply-chain and business data across its global fab network and to power AI agents on top of it, announced 2026-08-10. The deal replaces legacy change-data-capture infrastructure with a system streaming live equipment, process, and scientific data; Redpanda’s own engineers are embedded with GF teams, and “Tier-0” mission-critical systems are already live. This is a concrete data point on the thread’s open question of whether GlobalFoundries’ “AI-centric markets” strategy (declared at its 2026 Investor Day) is being executed internally, not just sold to customers as a foundry service — it sits alongside, not inside, the capex/margin story the thread otherwise tracks. ⚠️ No dollar figure was disclosed for the deal.

2026-08-05 — Q2 2026 print: the capex reversal widens further, stock falls on margin skepticism anyway

• GlobalFoundries beat its own Q2 guide — revenue $1.786B (above the $1.76B ± $25M guide, +9% sequentially, +6% YoY), non-IFRS EPS $0.46 (vs. ~$0.44-0.45 consensus), non-IFRS gross margin 29.9% (up from 25.2% a year ago). Filed as an SEC 6-K same day; call held 8:30am ET. (SEC EDGAR 6-K · GlobeNewswire via Manila Times)
• The capex/depreciation reversal this thread opened on is now wider, not narrower: capex $411M vs. $159M a year ago (+158% YoY), while depreciation kept falling to $307M from $335M — a bigger gap than Q1’s already-flagged $312M-capex/$311M-D&A near-parity. Adjusted free cash flow went negative (-$3M vs. +$277M a year ago). Communications infrastructure & data-center revenue (silicon photonics, SiGe) rose 62% YoY to $277M; management raised full-year guidance for that segment to 50-60% growth (from 30-40%). Q3 guide: $1.885B ± $25M revenue, $0.51 ± $0.05 non-IFRS EPS. Despite the beat, shares fell ~4-5% at the open — coverage attributes it to skepticism on the 30%-by-end-2026/40%-by- end-2028 gross-margin targets and lingering smartphone-segment weakness (smart mobile -6% YoY, automotive -10% YoY), not to anything in the print itself.

2026-07-29/31 — Second CHIPS award of the year: $300M for AI-datacenter photonics, another government equity stake

• The US Commerce Department signed a letter of intent for up to $300M in CHIPS Act funding to GlobalFoundries — the largest single award in an $874M package spread across seven companies for AI/HPC-adjacent semiconductor technology. Targets “SCALE” (Silicon-photonics Co-packaged Advanced Light Engine), aimed at 400 Gb/s optical interconnects for AI datacenters — not leading-edge logic, but infrastructure built around AI compute. The government takes a 1% equity stake in GlobalFoundries, reported worth ~$269M — explicitly compared in coverage to the Intel August-2025 CHIPS-to-equity precedent. (The Register · Benzinga)

2026-07-28/29 — AGM: board shrinks from 13 to 11, one director’s approval margin stands out

• GlobalFoundries’ 2026-07-28 AGM elected three Class II directors (Kerko 99.53%, Lazar 94.44%, Obeid 82.35% — the gap versus the other two is unexplained in any source found) and ratified PwC as auditor (99.98%). Elissa Murphy resigned (filing states no disagreement with the company); Martin Edelman did not seek re-election — board size fell from 13 to 11. (SEC 6-K)

2026-07-17/30 — Stock falls ~45% from the Mubadala sale price, no clear single cause

• GFS fell from $89.96 (the day of Mubadala’s May share sale) to $49.89 by 2026-07-30 — roughly 45% in two months, including a 5-7-day red streak in mid-to-late July that alone erased ~$5.8B of market value. Coverage attributes it to valuation compression (P/E ~41 vs. an S&P median ~24), profit-taking, and a broader semiconductor-sector selloff — not a company-specific miss. Three directors filed routine, small Form 4 sales July 20/29, read as scheduled pre-blackout trades rather than a distress signal. This is the weakest-sourced item in the crawl (single aggregator’s synthesis) but the magnitude of the move itself is well-corroborated. (Trefis / GuruFocus / Motley Fool, convergent)

2026-05-21/22 — First CHIPS award of the year: $375M quantum foundry, also structured as equity

• A letter of intent for up to $375M in CHIPS funding to build a domestic quantum-computing foundry — part of $2.013B across nine quantum-sector LOIs, each carrying a ~1% non-controlling government equity stake. GlobalFoundries launched a new Quantum Technology Solutions business unit the same day, with named partners PsiQuantum, Quantinuum, Diraq, Equal1, and Microsoft Quantum. This is the board’s existing “$375M quantum” figure, now dated and sourced precisely. (The Quantum Insider)

2026-05-26 — Mubadala trims its stake to 73%, while deepening board influence

• Mubadala sold 22M GlobalFoundries shares at $89.96/share (~$1.98B raised), cutting its stake from the board’s carried 82% to 73% — even as its own Chief Legal Officer, Samer Halawa, had joined GlobalFoundries’ board three months earlier (2026-02-03, Class III director, Strategy & Investment Committee). Less economic exposure, more direct strategic influence, at the same time. (AGBI)

2026-05-05 — Q1 2026 filing: the capex/depreciation gap nearly closes

• GlobalFoundries’ own SEC filing shows Q1 2026 capex nearly doubled year-over-year ($166M → $312M) while depreciation fell ($352M → $311M) — the two lines are now essentially at parity ($312M vs. $311M), a sharp reversal from Q1 2025’s $186M gap. The board’s carried “genuinely negative” thrust figure (capex $0.87B/yr vs. dep $1.27B/yr) describes a trailing-year state; this is the freshest primary data point, and it points the other way. Full-year 2026 capex is guided to 15-20% of revenue, raised year-over-year on oversubscribed capacity in silicon photonics, FDX, SiGe, and advanced packaging — demand-driven, not idle capacity. (SEC 6-K)

2026-02-03 — Mubadala’s own legal chief joins the board

• Samer Halawa, Mubadala’s Chief Legal Officer, elected to GlobalFoundries’ board as a Class III director and member of the Strategy & Investment Committee — three months before Mubadala trimmed its economic stake (above). (TipRanks)

2026 Investor Day — first-ever dividend, formal capital-return framework

• GlobalFoundries declared its first-ever dividend ($0.12/share, paid 2026-07-14) and a new framework targeting return of up to 50% of trailing-12-month non-IFRS adjusted free cash flow via dividends and buybacks (a $500M buyback was separately authorized in February 2026). CEO Tim Breen framed the growth strategy around “AI-centric markets” — AI datacenters plus “physical world” (auto/industrial/defense) applications — explicitly not a leading-edge-logic pivot. (GlobalFoundries IR)

2026-03-08 — Renesas deal deepens the automotive lane

• A multi-billion-dollar manufacturing agreement with Renesas for automotive-grade microcontrollers, production starting at US facilities mid-2026 and expanding internationally — reinforcing, not abandoning, GlobalFoundries’ “higher-value, long-life chips for autos/industrials” positioning against the leading-edge foundries. (Sahm Capital)

2025-06-04 — The $16B reshoring pledge (predates this crawl’s window, foundational context)

• GlobalFoundries pledged $16B to modernize its Malta, NY and Essex Junction, VT fabs — $13B for plant modernization, $3B for R&D (packaging, silicon photonics, gallium nitride) — naming Apple, SpaceX, AMD, Qualcomm, NXP, and GM as working customers. The base the 2026 CHIPS awards and Investor Day strategy build on. (Vermont Business Magazine)

Next to watch

• 2026-08-05, Q2 2026 earnings (before market open) — the first hard test of whether the Q1 capex/depreciation near-parity holds, reverses, or was a one-quarter anomaly, and whether it explains or is unrelated to the ~45% stock decline since late May.
