European Technology Hardware and Semiconductor Sector: UBS stays constructive on European semiconductors, with ASML, ASMI and STMicroelectronics preferred for AI-driven earnings upside.

Overview

This Q3 2026 preview assesses European technology hardware across semiconductor equipment, analog semiconductors and telecom equipment. UBS's central conclusion is that AI-led capacity expansion should sustain a strong multiyear equipment cycle, favoring ASML, ASM International and STMicroelectronics, while telecom equipment remains structurally less attractive.

Core views

UBS remains constructive on European semiconductors heading into Q3 2026 results despite volatile AI sentiment and de-grossing prompted by higher bond yields. Its preferred positioning is centered on clear AI exposure, potential earnings upgrades and visibility into medium-term growth. ASML is the top pick, followed by ASM International and STMicroelectronics; UBS forecasts 7-20% upside to consensus EPS for these preferred names in 2027-28. The principal sector argument is a stronger and longer wafer-fab equipment cycle driven by AI-related capacity expansion in advanced logic and memory. UBS raised its WFE forecasts for 2026-28 after supply-chain work, new cleanroom announcements, capacity-expansion evidence and supplier messaging indicated that spending could remain ahead of demand. It expects total WFE to rise from about $158bn in 2026 to about $226bn in 2027, or roughly 43% year-on-year, with memory up about 53%—DRAM up about 60% and NAND about 30%—and foundry/logic up about 34%. For 2028, UBS forecasts total WFE of at least about $275bn, with potential upside to $300bn if foundry spending exceeds its expectations; overall WFE would rise about 22%, led by foundry/logic growth above 30%, while memory rises about 10%. UBS argues consensus still underestimates both the persistence and breadth of AI spending and the company-specific drivers that can allow European equipment suppliers to outgrow the broader WFE market over the next two to three years. Its 2027-28 EPS forecasts are more than 10% above consensus for most covered equipment names. For ASMI, UBS forecasts revenue growth of 36% in FY27 and 33% in FY28, versus consensus expectations of 29% and 19%, respectively; this results in EPS estimates 10% above consensus in 2027 and 20% above in 2028. Further epitaxy and ALD share gains and leading-edge logic layer wins are identified as potential catalysts. ASML is the strongest expression of the equipment thesis. UBS expects low-NA and immersion capacity targets currently set at about 30% growth in both 2027 and 2028 to be raised above 30% as AI demand improves visibility. It believes ASML could guide for FY27 group revenue growth above 30%, versus consensus at 28% and UBS at 33%. Pricing is described as the largest earnings lever because EUV and immersion platforms account for about 80-85% of revenue; UBS expects customer negotiations to enable further price increases and sees 15-20% EPS upside to consensus by 2028. Accelerating High-NA adoption, supported by announcements from Samsung and TSMC and progress in 12-inch photomasks, could add upside, particularly in DRAM. The analog outlook is positive but selective. AI infrastructure, industrial automation and a prospective automotive inventory replenishment cycle support the recovery, yet UBS sees uneven end-market conditions, including weak China automotive demand, persistent oversupply and changing competition in China and AI-adjacent markets. Its automotive semiconductor forecast is broadly unchanged: about 10% revenue growth in 2026 and about 12% in 2027, revised down from 14% previously. Distributor data indicate a supportive pricing environment: average pricing rose 1% month-on-month and 16% year-on-year, while inventories fell 3% month-on-month and were generally stable. STMicroelectronics is UBS's preferred analog idea, with its 2027 EPS estimate about 20% above consensus. For STMicroelectronics, UBS expects Q4 revenue growth of about 10% quarter-on-quarter, ahead of normal seasonality of about 7%, driven by automotive demand from customers including Tesla and Mobileye, improving European OEM demand, datacenter ramp-up and industrial recovery. It forecasts silicon-photonics revenue of about $2.0bn in 2027 and about $2.5bn in 2028. Together with AI power products, UBS estimates datacenter revenue of about $2.5bn in 2027, or about 14% of group sales, rising to about $3.8bn and 19% of sales in 2028. Its 2026 adjusted EBIT estimate is 6% above consensus. Telecom equipment remains less favored than semiconductor equipment and analog semiconductors. UBS sees Ericsson facing gross-margin pressure from cost inflation, product mix and persistent pricing headwinds, and identifies geographic mix as downside risk to H2 2026 revenue and margins. Nokia faces similar industry pressures, although AI-driven optical-networking demand could support Q4; UBS estimates Q4 revenue of €6.4bn and EBIT margin of 19.8%, modestly above consensus. Overall, however, UBS considers telecom equipment's risk-reward less compelling and identifies Ericsson as its least preferred name. Across the Q3 preview, UBS also notes differentiated company-specific setups. Aixtron's optical-datacenter order demand is strong but power-market demand remains subdued, with UBS forecasting FY26 power sales down 44% year-on-year. ams-OSRAM's revenue outlook is broadly in line, but deleveraging progress and the scale and timing of its microarray interconnect and microVCSEL opportunities are key. Besi's possible upside hinges on China 2.5D activity, Apple content and large hybrid-bonding orders. SUSS has strong advanced-packaging orders, although it cited geopolitical and economic uncertainty. Technoprobe has raised 2026 guidance, but UBS expects custom-ASIC revenue to begin ramping only from Q4 2026 as 3nm volumes build through 2027.

Analysis framework

UBS combines bottom-up company forecasts and supply-chain work with evidence from cleanroom and capacity announcements, supplier commentary, distributor pricing and inventory data, company guidance, and comparisons with consensus estimates. It then evaluates earnings sensitivity, end-market demand, share gains, margins and valuation multiples for each covered company.

Impact & implications

UBS believes AI capital spending should continue to differentiate semiconductor equipment and selected analog companies from the broader European technology hardware universe. The report favors names with structural AI exposure, pricing power and share-gain potential, while treating weak China auto demand, uneven recovery and telecom margin pressure as reasons to remain selective.

Risks

• AI investor sentiment remains volatile, and higher bond yields have prompted de-grossing.
• Weak Chinese domestic automotive demand and continued oversupply could limit the analog-semiconductor recovery.
• Competitive dynamics in China and AI-adjacent markets may widen sector outcomes in H2.
• Telecom-equipment margins face continuing cost inflation, unfavorable product mix and pricing pressure.
• Technology-company results are difficult to forecast because operating models, competitor actions and delivery models can change rapidly.

What to watch

• Whether foundry spending supports the upper end of UBS's 2028 WFE forecast and whether ASML raises its 2027-28 capacity targets.
• ASML commentary on EUV and immersion pricing, High-NA shipment acceleration and DRAM demand.
• ASMI commentary on epitaxy and ALD share gains and additional leading-edge logic layer wins.
• China automotive demand, semiconductor inventory conditions and distributor pricing trends.
• STMicroelectronics Q4 automotive, industrial and datacenter demand, including silicon-photonics and AI-power progress.
• Ericsson gross-margin progression and Nokia optical-demand and AI-and-cloud order trends.
• Aixtron commentary on SiC and GaN demand; ams-OSRAM deleveraging and new-product opportunities; Besi hybrid-bonding orders; and SUSS geopolitical and economic conditions.
