Soitec’s share price has climbed almost sevenfold this year, rising from roughly €23 in January to €154 on Monday afternoon in Paris. The surge points to where Europe’s technology strategy must focus if the continent hopes to compete in artificial intelligence. Bank of America upgraded the stock from Neutral to Buy on Friday and lifted its price target to €300, implying more than 90% additional upside. The wager isn’t on flashy chip design. It’s on a French company’s command of an essential, unglamorous technology: engineered silicon wafers that help AI infrastructure run faster while using less power.
Europe has lost the race to design processors for AI systems. Nvidia dominates, while China and the United States have cornered the market. Yet Soitec, based in Bernin near Grenoble and employing more than 2,000 people, controls another essential piece: silicon photonics wafers. These components use light rather than electrical signals to connect processors, providing faster, more energy-efficient alternatives to traditional copper connections.
Why This Is European Competition
The French research institute CEA-Leti spun Soitec out 34 years ago. The company holds more than 4,700 patents and supplies the specialised wafers used to manufacture silicon photonics chips. Bank of America analysts estimate Soitec currently holds approximately 95% market share in supplying Photonics-SOI wafers. Taiwan’s GlobalWafers and other competitors are trying to enter the market, but the bank expects Soitec’s technological expertise and decades of manufacturing experience to shield its position.
Chief Technology Officer Christophe Maleville told Euronews: “Our job is to run faster than the competition.” His words capture Europe’s central challenge. We can’t outspend the Americans or match China’s labour costs. We must outthink them through precision manufacturing and engineering depth. Soitec is doing exactly that, and the market is rewarding it.
The company’s recent performance tells two stories. Annual revenue fell 34% to €592 million in fiscal 2026, while its smartphone business, which accounted for roughly half of revenue last fiscal year, contracted 43%. Mobile communications sales plunged again in the June quarter as customers reduced inventories. Bank of America expects the mobile business to hit its lowest point this fiscal year, though recovery isn’t guaranteed.
The photonics story looks entirely different. In September, Soitec projected that photonics revenue in the financial year ending March 2027 would reach between 2.5 and three times the previous year’s level. The company also forecast approximately 50% growth in total revenue for the September quarter. Edge & Cloud AI generated 57% of sales in the June quarter alone.
The Fiscal Picture
Bank of America projects photonics revenue will grow from €92 million in fiscal 2026 to approximately €680 million in fiscal 2029. That would amount to almost half of projected group revenue of €1.43 billion, compared with just 16% last fiscal year. More critically, the bank estimates photonics wafers retain about 80 cents per euro of sales after raw material costs, against 56 cents for Soitec’s other products. It expects the company’s gross profit margin to climb from 16% to 44% by fiscal 2029.
That margin expansion matters for European industrial strategy. High-margin manufacturing creates sustainable employment, funds research and development, and generates tax revenue. It’s the opposite of China’s low-cost, high-volume model. Soitec’s approach—technological dominance in a niche market with pricing power—is the template Europe needs.
Soitec expects multi-year capacity agreements with eight of its roughly ten largest photonics customers. Those deals could make future demand more predictable and support investment in production capacity. Bank of America expects the company to announce an extension of its Singapore manufacturing plant in the coming months, potentially costing around €700 million. Governments and investors alike will closely watch that decision on where to place European manufacturing capacity.
The Demand Forecast
Bank of America analysts Oliver Wong and colleagues estimate the wafer area needed for photonic chips will expand by approximately 60% annually between 2026 and 2030. The rate reflects the enormous infrastructure buildout needed to train and run AI models. It also reflects one stark fact: silicon photonics technology is becoming essential, not optional, for data centre efficiency.
At approximately €154 per share, the stock trades at nearly 96 times Bank of America’s projected earnings for the financial year ending March 2027. That valuation could leave investors exposed if AI infrastructure spending slows or competing technologies gain ground. Soitec is scheduled to publish first-half results on 18 November.
The stock surge coincides with a broader shift in European technology priorities. For years, Brussels focused on regulating Big Tech and protecting legacy industries. Soitec’s rise points to another path: identify where European manufacturing expertise is genuinely irreplaceable, protect it from acquisition by strategic competitors, and let companies compete globally without the regulatory friction that slows innovation elsewhere.
Why This Matters:
Soitec’s trajectory shows Europe can compete in critical technology sectors—not by copying American or Chinese strategies, but by mastering precision manufacturing and engineering depth where others can’t easily follow. A single French company now holds 95% global market share in a technology that will be essential to AI infrastructure for the next decade. That’s not luck. It reflects sustained investment in research institutes like CEA-Leti, patent protection, and manufacturing discipline. The question for European policymakers is whether they’ll recognize and encourage this model, or keep regulating and taxing companies like Soitec as though they were the problem rather than the solution. The €700 million Singapore expansion decision suggests the answer may already be clear.
