Europe's semiconductor sector is structurally different from the US or Asian chip industries. Europe is not a volume chipmaker — it has no TSMC equivalent. Instead, it is a dominant provider of the equipment, materials, and specialty chips that the entire global semiconductor supply chain depends on.
ASML makes the only machines capable of producing the world's most advanced chips (EUV lithography). ASM International and BESI together hold leading positions in atomic layer deposition and advanced chip packaging equipment. Soitec provides the engineered substrates that enable most advanced-node chips. Infineon leads in power semiconductors. STMicroelectronics supplies the automotive and industrial chip market.
These are not speculative technology companies. They are deeply embedded in global manufacturing supply chains with switching costs that make their positions durable. Many were substantially cheaper in early 2026 than their historical premium to US semiconductor peers would suggest.
The European semiconductor supply chain: a map
Understanding what each company does prevents common mistakes in sector analysis (treating ASML as comparable to Nvidia, for example).
Tier 1 — Semiconductor equipment (upstream)
ASML (Netherlands) — Euronext Amsterdam / Nasdaq The world's only manufacturer of EUV (Extreme Ultraviolet) lithography machines — the equipment that enables chips below 7nm. Every advanced chip manufacturer (TSMC, Samsung, Intel) is dependent on ASML machines. This is one of the most durable technology monopolies in existence.
Market context (June 2026): ASML is trading at approximately a 6% premium to US large-cap semiconductor peers on 12-month forward P/E — compared to a 10-year average premium of 84%. If the historical premium reflects genuinely unique competitive position, the current valuation represents a notable opportunity.
ASM International (Netherlands) — Euronext Amsterdam Atomic layer deposition (ALD) equipment — the process for depositing ultra-thin, uniform films on semiconductor wafers. ALD is essential for advanced-node chips; ASM International has a leading market position globally.
Besi (Netherlands) — Euronext Amsterdam Advanced semiconductor assembly and packaging equipment. Packaging is becoming a critical bottleneck as chip dimensions approach physical limits — advanced packaging (chiplets, heterogeneous integration) requires Besi's equipment. 14 buy recommendations from analysts vs. 2 sell as of mid-2026.
Aixtron (Germany) — XETRA Equipment for compound semiconductor (GaN, SiC) production. Compound semiconductors are used in power electronics, 5G infrastructure, and electric vehicle inverters. Aixtron has high exposure to the EV and clean energy transition.
Tier 2 — Semiconductor materials and substrates
Soitec (France) — Euronext Paris Engineered semiconductor substrates (SOI — Silicon on Insulator). Soitec's substrates are in nearly every smartphone and advanced automotive chip. Near-monopoly position in FD-SOI substrates used for low-power applications.
AT&S (Austria) — Vienna Stock Exchange (Wiener Börse) Advanced printed circuit boards (PCBs) and IC substrates. AT&S supplies high-end IC substrates for Apple, Intel, and Qualcomm chipsets. Not a semiconductor company per se, but deeply embedded in the same supply chain.
Tier 3 — Integrated device manufacturers (IDMs)
Infineon Technologies (Germany) — XETRA Power semiconductors — chips that manage electrical power in electric vehicles, industrial motors, solar inverters, and data center power supplies. Infineon is the global leader in automotive semiconductors and a key beneficiary of electrification.
STMicroelectronics (France/Italy) — Euronext Paris, NYSE Diversified analog and mixed-signal chips for automotive, industrial, and IoT markets. Heavy exposure to the automotive semiconductor market; earnings affected by the automotive inventory correction of 2024–2025.
Melexis (Belgium) — Euronext Brussels Automotive semiconductor ICs — microcontrollers, Hall sensors, LIN/CAN transceivers. Deeply embedded in automotive electronics. Small-cap quality compounder: 20%+ ROIC consistently, low debt.
SÜSS MicroTec (Germany) — XETRA Lithography and wet processing equipment for niche semiconductor applications (MEMS, power devices, LED). Smaller than ASML but serves markets where specialized equipment is preferred.
How to screen European semiconductor stocks
Primary screen: quality metrics for equipment companies
Semiconductor equipment companies (ASML, ASM International, BESI) share specific financial characteristics: high gross margins (40–60%), strong ROE and ROIC, capital-light business models (they build machines, not fabs), and significant order backlogs that provide revenue visibility.
Screen parameters for equipment companies:
- Gross margin > 40%
- ROIC > 15%
- Net cash or net debt/EBITDA < 1.0 (equipment companies should not be leveraged)
- Revenue growth (3Y average) > 10%
Primary screen: quality metrics for IDMs (Infineon, STM)
Integrated device manufacturers are more capital-intensive. They operate their own fabs, carry more fixed-cost exposure, and are more cyclically sensitive than equipment companies.
Screen parameters for IDMs:
- Gross margin > 35%
- Operating margin > 10%
- ROE > 15%
- Net debt/EBITDA < 2.0
Valuation overlay
For both equipment companies and IDMs:
- P/E below 30 — screens out the most expensive names without excluding quality
- EV/EBITDA below 20 — appropriate ceiling for semiconductor companies with durable competitive positions
- FCF yield above 2.5% — confirms cash generation is real, not accounting artifact
Companies passing a combined screen (June 2026 context)
Based on publicly available analyst commentary and current valuations:
ASML — P/E significantly below historical premium relative to US peers. EUV monopoly position intact. Strong order backlog.
BESI — Strong buy consensus from analysts. Advanced packaging exposure positions it well for chiplet architecture trend.
Melexis — Consistently screens well on ROIC and margin stability. Small-cap with limited institutional attention.
ASM International — ALD secular growth tailwind. Trades at below-historical premium.
Aixtron — EV/GaN transition plays into long-term demand, though 2025 order softness created valuation entry.
Note: Soitec and AT&S are more sensitive to end-market cycles (smartphone volumes, PC demand) and screen less consistently across the cycle.
Why European semiconductor stocks were cheaper than US peers in early 2026
The divergence between European and US semiconductor valuations in 2025–2026 had several drivers:
1. European market discount. European equities broadly trade at 25–35% discount to US equivalents. This discount applies to semiconductor companies regardless of their actual competitive position.
2. US AI premium to European industrials. US semiconductor companies (Nvidia, AMD, Broadcom) benefited from extreme AI-compute demand premiums that re-rated the entire US semiconductor sector. European companies — primarily serving industrial, automotive, and equipment markets rather than AI compute — did not participate in this re-rating despite having equally durable competitive positions.
3. Automotive semiconductor correction. Infineon and STMicroelectronics have substantial automotive exposure. The automotive semiconductor inventory overhang of 2024–2025 compressed earnings and valuations even for companies with strong medium-term demand tailwinds.
4. China export control uncertainty. ASML's China business represents a significant revenue share. Export control uncertainty created valuation overhang even as the non-China business grew strongly.
Sector-specific risks for European semiconductor stocks
Geopolitical risk: China export restrictions. ASML and ASM International have significant China exposure. Further restrictions on semiconductor equipment exports to China would reduce their addressable market. This is the most important risk for European equipment companies and is explicitly flagged in their annual reports.
Automotive cycle. Infineon, STM, and Melexis are exposed to automotive build rates. A global auto production slowdown or extended EV ramp delay (vs. battery-powered projections) would directly impact their earnings.
Concentration risk in equipment. ASML, BESI, and ASM International collectively dominate European semiconductor equipment. The sector is highly correlated — they tend to move together in response to semiconductor capex cycle news (TSMC guidance, Samsung investment plans, Intel IDM 2.0 progress).
Currency. European semiconductor stocks report in EUR. Revenue from the US (in USD) and Asia (in USD or JPY) creates natural hedges, but currency fluctuations affect reported earnings.

Frequently asked questions
Is ASML a good investment in 2026?
ASML's competitive position — the only EUV lithography manufacturer — is unchanged. The valuation question is whether the current premium to US semiconductor peers (6% as of 2026 vs. 84% historical average) reflects a permanent or temporary compression. Investors who view the discount as temporary have a valuation case; investors who view export controls as a permanent impairment of the China business see a structural issue. The consensus analyst view (UBS top pick) leans toward the opportunity interpretation.
Which European semiconductor stocks are the best value in 2026?
Valuation is dynamic and changes with earnings releases. At the time of this writing, ASML and BESI are most frequently cited by analysts as attractively valued relative to their competitive positions. Melexis screens consistently well for quality investors. STM and Soitec carry more near-term cycle uncertainty.
How do European semiconductor companies compare to US chip stocks?
European companies are primarily in equipment (ASML, BESI, ASM), materials (Soitec), and specialty chips (Infineon, STM, Melexis). They are not in high-volume advanced logic (no European TSMC or Fabless equivalent). European semiconductor companies tend to have more industrial/automotive exposure and less AI/data center exposure than US counterparts like Nvidia or AMD.
