STMicroelectronics
Franco-Italian chipmaker building automotive, industrial, and power semiconductors in its own fabs.
On the record
Checkpoint: Q3 2026 earnings report, watch gross margin trend and photonics ramp against $1B 2026 target
The call
ST is recovering from a deep cyclical trough with a real AI-photonics tailwind, while Chinese rivals chip away at its automotive and power business and margins stay well below peer levels.
STMicroelectronics designs and manufactures computer chips, including semiconductors for cars, data centers, and other electronics. It is somewhat hard to replace quickly because it owns its own factories (which take years and billions to build), has long-standing relationships with car makers who trust its safety track record, and is now producing special chips for AI data centers with companies like Amazon and Nvidia. The one thing that could change everything: if the company cannot keep its profit margins healthy while ramping up these new AI chips, or if Chinese competitors keep stealing ground in automotive chips and silicon carbide products, then the recovery story falls apart and the restructuring (laying off 5,000 workers through 2028) could become a sign of deeper trouble rather than a cleanup.
Why
01
AI pressure: None apparent. AI datacenter buildout feeds ST directly: PIC100 silicon photonics for AWS and NVIDIA now in high-volume production. Could AI do the core job? Unlikely.
02
Bigger players: Chinese chipmakers (Horizon Robotics, SiEngine, Black Sesame in ADAS; SICC in SiC substrates). Chinese rivals are gaining ground in ADAS chips and SiC substrates, areas that fed ST's 24% automotive revenue drop in FY2025. Could a giant copy it? No, they are blocked.
03
What protects it. ST owns its 300mm silicon and 200mm SiC fabs and holds automotive safety qualifications built over years, which locks it into long OEM design-in cycles.
What would change this call
STMicroelectronics Q3 2026 earnings report in October 2026 shows gross margin below 35%. would indicate margin compression is durable, not a temporary trough.
STMicroelectronics automotive or SiC revenue share loss to Chinese chipmakers accelerates in 2026-2027 filings. would confirm Chinese rivals are displacing it in core franchises, not just probing.
Silicon photonics data-center revenue reported below the $1 billion 2026 target. would show the AI-datacenter growth thesis is faltering.

Key numbers
- FY2025 revenue $11.8B, down 11.1% year over year
- Q2 2026 net income $222M, swinging from a year-ago loss
- Data-center revenue guided above $1B in 2026, $2B in 2027
Named risks
- Gross margin near 37%, below top-tier analog/power IDM peers like TI.
- Chinese competitors gaining share in automotive ADAS and SiC substrates.
- French/Italian government friction over 5,000-job restructuring site allocation.
- Silicon-photonics growth concentrated in a small number of hyperscaler customers.
- Automotive and industrial cyclicality (FY2025 auto revenue down 24%).
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Infineon Technologies | contesting | Infineon had >$8B automotive sales in 2024 and is first NVIDIA HVDC power partner, per Sep 2025 comparison |
| Horizon Robotics, SiEngine, Black Sesame | losing to | Chinese ADAS chipmakers gaining ground per Yole Group analysis, Aug 21, 2025 |
| SICC (via Wolfspeed comparison) | gaining on | Reported overtaking Wolfspeed on 8-inch SiC yield/cost, single-source claim, May 3, 2026 |
| Texas Instruments | losing to | ST margin 'well below' TI-class analog/power IDM peers, per Jul 23, 2026 earnings commentary |
Questions people ask
- Is STMicroelectronics profitable in 2026?
- Yes. STMicroelectronics returned to profit in Q2 2026 with net income of $222 million, versus a loss a year earlier, on net revenues of $3.49 billion, up 26.0% year over year, as of June 30, 2026.
- Is STMicroelectronics laying off workers?
- Yes. ST expanded restructuring in June 2025 to cut about 5,000 jobs over three years, mostly voluntary, building on an April 10, 2025 plan for up to 2,800 cuts including roughly 1,000 in France.
- Who owns STMicroelectronics?
- No single private owner controls it. About 27-28% of capital and votes are held via STMicroelectronics Holding N.V./B.V., split roughly 50/50 between French and Italian state-linked entities, as of January 26, 2026; the rest is free float.
- Could AI replace STMicroelectronics?
- No. AI cannot replicate ST's owned 300mm silicon and 200mm SiC fabs or automotive-safety qualification history. AI is a tailwind instead: its PIC100 silicon-photonics platform entered high-volume production for AI data centers on March 9, 2026, co-developed with AWS.
- Who is STMicroelectronics' biggest competitor?
- Infineon Technologies is ST's closest rival in automotive and power semiconductors. Chinese entrants Horizon Robotics, SiEngine, and Black Sesame were reported gaining ground in automotive ADAS chips as of August 21, 2025, per Yole Group analysis.
- Is STMicroelectronics losing ground in silicon carbide?
- Partly. A single-source industry newsletter reported Chinese supplier SICC overtook Wolfspeed on 8-inch SiC yield and cost as of May 3, 2026, even as ST expands its own SiC fab capacity at Catania and Agrate, Italy.
