GlobalFoundries (GFS) Q3 2026 earnings review
GlobalFoundries lifts margins on AI chips, but share count rises
GlobalFoundries, the contract chipmaker, is lifting its factory margins on data center demand while paying for government backing with new shares. Revenue rose 13% from a year ago, and gross margin excluding one-offs reached 31.4% as chief executive Tim Breen pointed to data center growth. However, issuing 9.9 million shares to the US government caused a $441 million charge and a net loss, while working capital drained cash flow.
| Revenue | $1,899M +12.5% from a year ago |
|---|---|
| Gross margin, excluding one-offs | 31.4% +5.4 percentage points from a year ago |
| Profit per share (IFRS) | $(0.49) includes $441M US government share charge |
| Fourth-quarter revenue outlook | $2,000M middle of the range: +9.3% from a year ago |
⚖️ Verdict: 🟢 Bullish
The story got better because the margin expansion is holding and the company locked in a $2 billion packaging deal with rival TSMC. The fourth-quarter outlook puts operating margin excluding one-offs at 19.8% in the middle of the range as operating expenses step down. One caution: the government deals bring real dilution, lifting the fourth-quarter share count to 575 million with more share issuances still to come.
The question now is whether data center optical demand stays strong through 2027 and outweighs the rising share count and weak cash conversion. Bulls see multi-year capacity wins with TSMC and Marvell, while sceptics see a concentrated build cycle and heavy capital needs that leave little free cash flow for shareholders. The full segment tables in the quarterly filing and the first-quarter 2027 outlook will test both views.
🐂 Bull Case
Data Center Demand Lifted Gross Margin Past 31%
"We delivered strong results in the third quarter, with record non-IFRS gross margin reflecting a richer mix of business across high-value, high-growth AI applications," chief executive Tim Breen said. GlobalFoundries makes semiconductors for chip designers, and it is shifting factory space toward optical networking and data center chips. Breen noted "record year-over-year revenue growth in Communications Infrastructure and Data Center" during the quarter.
- Gross margin, excluding one-offs: 31.4%, up 5.4 percentage points from a year ago
- Cost of making the chips: 69.9% of revenue, down 5.3 percentage points from a year ago by our math
- Revenue per wafer: $2,935 by our math, up 4.7% from a year ago as prices and product mix improved
That shift matters because data center and optical chips carry higher margins than smartphone parts. Even with wafer volume up 7.5%, revenue grew 12.5%, ending a stretch of falling revenue per wafer. The fourth-quarter outlook puts gross margin excluding one-offs at 31.5% at the middle of the range, showing the gain is holding.
What to watch: the exact dollar revenue for Communications Infrastructure and Data Center in the quarterly filing. A figure above $300 million would keep the segment on track for the company's full-year growth plan.
TSMC and Marvell Deals Back Optical Packaging
GlobalFoundries makes silicon photonics (chips that move data using light) and silicon germanium (high-speed signal chips) for data centers. Critics worried that as data centers move to co-packaged optics, where optical and compute chips sit inside one package, rival TSMC would capture the work. In October, GlobalFoundries signed a multi-year, $2 billion manufacturing agreement with TSMC to build silicon interposers, the base layer that connects chips inside an advanced package.
The company will make these parts at its Malta, New York plant "for TSMC’s CoWoS advanced packaging ecosystem", with volume production starting in the first half of 2028. It also expanded a multi-year deal with Marvell in Vermont for silicon germanium chips used in optical transceivers and co-packaged optics. Working as TSMC's US supply partner turns a packaging rival into a customer, though TSMC revenue will not start until 2028.
What to watch: commentary on the earnings call about whether the second design win for SCALE, its optical packaging platform, completed design work in the third quarter. A completed design would show direct packaging wins alongside the TSMC deal.
Positives this quarter didn't test
Two standing drivers had no new numbers in the preliminary release because they depend on future periods or detailed segment tables.
- Chip design and licensing revenue: the company bought processor designer MIPS and Synopsys's ARC business to sell more intellectual property, and the quarterly filing will show whether Technology Services revenue rebounded from $201 million last quarter.
- Customer price increases: management agreed on higher wafer prices across several chip lines last quarter, and the first quarter of 2027 will show their effect on revenue.
🐻 Bear Case
US Deals Bring Funding, But Dilute Shareholders
Breen highlighted "the significant customer and government partnerships announced during the quarter" as a pillar of the company's strategy. In October, a US-Japan initiative selected the chipmaker to run two new New York plants backed by up to $21 billion in funding, where it will be "compensated through management and technology fees over the life of the project". It also amended its US CHIPS Act award to direct $955 million toward advanced packaging and
"the first U.S.-based source of silicon interposers". That government backing came with an equity cost for existing owners. In September, GlobalFoundries issued 9.9 million shares to the US government, booking a $441 million non-cash charge that pushed the quarter to a $270 million net loss. Even before that charge, research and administrative costs jumped to 18.0% of revenue from 13.3% a year ago on acquisition and workforce charges.
More dilution is coming because the fourth-quarter outlook lifts the diluted share count to 575 million from 558 million, and notes that charges for "additional common share issuances to the USG based on recent announcements" are not yet included.
What to watch: the total number of shares promised to the US government in the quarterly filing. A higher share grant reduces each current shareholder's slice of future earnings.
Working Capital and Factory Spending Drained Cash
GlobalFoundries has maintained a full-year outlook for adjusted free cash flow (operating cash flow minus factory spending, plus government grant cash) of about 10% of revenue. In the third quarter, adjusted free cash flow fell 70% from a year ago to $136 million, or 7.2% of revenue. Operating cash flow dropped 43% to $341 million because working capital tied up $272 million, while factory spending net of grants rose to $205 million.
Through the first nine months of 2026, the chipmaker generated $366 million of adjusted free cash flow, which is 6.9% of sales by our math. To reach its 10% full-year plan, by our math the company must generate about $366 million in the fourth quarter alone, or 18.3% of guided revenue. Uncollected customer bills and prepayments on the balance sheet have climbed $344 million since December.
What to watch: whether management holds the 10% full-year free cash flow margin target on the conference call. Holding it would require fourth-quarter cash generation to double the first nine months' pace.
Risks this quarter didn't answer
Four standing concerns could not be checked in the preliminary release because end-market tables and balance-sheet footnotes arrive in the quarterly filing.
- Smart Mobile Devices slump: phones made up 36% of sales last quarter, and the quarterly filing's segment table will show whether handset cuts kept dragging on revenue.
- Customer prepayments: contract liabilities fell by $276 million in the first half of the year, and the filing's footnote will show how much deposit cash rolled off in the third quarter.
- Back-end-loaded Automotive and IoT plans: Breen cited growth in both markets, and the segment table will show if they hit the steep second-half pace needed for their full-year targets.
- 2027 optical demand digestion: whether data center customers slow their optical chip orders after the 2026 build-out will be tested by the first-quarter 2027 outlook.
👓 Other Themes
Singapore Power Deal and Steady Dividend
In September, GlobalFoundries signed a long-term manufacturing agreement with Monolithic Power Systems to run that customer's power-management chip technology at its 300mm factory in Singapore. Volume production is planned for early 2027, targeting automotive systems, industrial robotics and AI data center power stages. Separately, the board approved a quarterly dividend of $0.12 per share payable in January 2027, after spending $100 million on share buybacks in the third quarter.
💲 Other KPIs
Shipments of 300mm-equivalent silicon wafers rose 7.5% from a year ago and 3.5% from last quarter. Volume has grown between 6.6% and 7.6% from a year ago in each quarter of 2026, showing steady factory utilization alongside better product mix.
Receivables, prepayments and other current assets — money owed by customers plus advance payments made by the company — climbed 21.8% from $1,578 million at the end of 2025. That buildup contributed to the $272 million working capital cash drain in the third quarter.
Total cash and marketable securities fell from $3,303 million last quarter and $3,989 million at the end of 2025. The chipmaker spent $100 million on share buybacks, $66 million on dividends and $46 million on acquisitions during the quarter, while total debt excluding leases stood at $1,136 million.
🔮 Guidance
New. The plan calls for $2.0 billion at the middle of the range, up 5.3% from this quarter and 9.3% from a year ago by our math. Growth slows from 12.5% in the third quarter because the fourth quarter compares against a stronger $1,830 million period last year. The company has beaten its revenue midpoint in every quarter of the past year by an average of 1.1%.
New. The middle of the range is 31.5%, up 0.1 percentage points from the third quarter and 2.5 points above a year ago. Including share-based pay, the IFRS gross margin outlook is 29.7% to 31.7% (30.7% in the middle, up from 30.1% this quarter).
Cut. Management previously indicated fourth-quarter operating expenses would stay near the third quarter's $260 million plan, so the $235 million middle of the range lowers spending by $22 million from this quarter's $257 million actual. Including $52 million of share-based pay, IFRS operating expenses are planned at $277 million to $297 million.
New. The outlook steps up to 19.8% in the middle of the range from 17.9% this quarter and 18.3% a year ago, helped by higher revenue and lower operating expenses. On an IFRS basis, operating margin is planned at 14.7% to 18.1% (16.4% in the middle).
New. At the $0.59 middle of the range, profit per share rises 11.3% from this quarter and 7.3% from a year ago by our math. Per-share growth lags operating profit growth because the planned diluted share count rises 3.0% to about 575 million shares. IFRS diluted EPS is planned at $0.42 to $0.52, before any further US government share charges.
❓ Key Questions
How many more shares will go to the US government?
The company issued 9.9 million shares to the US government in September for a $441 million charge, guided fourth-quarter diluted shares up by 17 million to 575 million, and warned of additional share issuances ahead.
What were the third-quarter revenues by end market?
The preliminary release omitted the end-market revenue table. Investors need the exact figures for Communications Infrastructure and Data Center, Smart Mobile Devices, Automotive and IoT to check the second-half growth targets.
How will fourth-quarter free cash flow reach $366 million?
Nine-month adjusted free cash flow is $366 million after a $272 million third-quarter working capital outflow. Hitting the full-year 10% margin target requires matching that nine-month total in a single quarter.
Did customer prepayments keep shrinking in the third quarter?
The condensed balance sheet combines contract liabilities into other liabilities. After customer deposits fell by $276 million in the first half, the footnote is needed to see if new advance payments have started.
