Soitec secures multi-year deals as AI wafer demand drives photonics revenue to triple

Soitec Capitalizes on Surging AI Wafer Demand

French chip materials maker Soitec is securing multi-year supply agreements with over 10 customers as AI wafer demand accelerates across the semiconductor industry1

1

. The company's CEO Laurent Remont told Reuters that around 80% of capacity reservation agreements with photonics customers should be signed within a week or two, with the remainder expected within a month2

2

. These multi-year supply agreements include deposits and fixed pricing, marking a strategic shift as Soitec uses market dynamics to balance value delivery with pricing power.

Silicon Photonics Revenue Set to Triple

Soitec's photonics-SOI revenue trajectory demonstrates the explosive growth in AI data center optics. The company told investors last month that photonics-SOI revenue would more than double this financial year from slightly above $100 million1

1

. Remont now calls $200 million "absolutely a floor" for current expectations3

3

. Even more remarkably, for the full 2026-2027 fiscal year, photonics-SOI revenue is expected to be 2.5 to 3 times that of fiscal 2025-2026, potentially reaching $750 million according to New Street Research4

4

. This acceleration reflects structural rather than cyclical factors, positioning Soitec for sustained growth.

Dominant Market Share in Critical AI Infrastructure

Soitec supplies the substrate underpinning almost all silicon photonics chips, with UBS estimating the company holds a 95% market share2

2

. Demand for silicon photonics has surged as hyperscalers increasingly use optical connections to move data inside AI infrastructure, where copper links are becoming less attractive because of power and performance constraints1

1

. Silicon photonics replaces electrical interconnects with optical networking that radically speeds data transfer speeds while delivering better energy efficiency4

4

. The company's stock has almost quadrupled this year as demand for AI-related optical networking has accelerated, with shares jumping 12.4% to 125.9 following the latest announcements4

Strategic Contract Terms Ensure Customer Commitment

The contracts fix a price and require a deposit tied to committed demand. Customers that take the agreed volume get the deposit back; those that fall short forfeit it1

1

. Volumes above the agreed level trigger new pricing discussions. "That's a way for us to have our customer with skin in the game," Remont said3

3

. Customers must also share inventory data, a requirement aimed at preventing companies from over-ordering capacity to keep wafers away from competitors2

2

. The cash deposits have not yet been paid and will arrive in stages as customers ramp production.

Capacity Expansion Without New Fabrication Plants

Soitec does not expect to need a new plant until around 2029, according to Remont1

1

. The company is pursuing capacity expansion through three levers: shifting output between businesses using shared underutilized facilities, installing additional tools in existing cleanroom space, and equipping an unequipped building in Singapore that could add capacity within six to 12 months if required2

2

. The cleanroom capacity includes part of a French facility originally built for silicon carbide production, which was written down by 41 million euros ($47.7 million) last year1

1

. Soitec produced photonics-SOI only in France until five months ago but has since qualified customers at a facility in Singapore. Remont sees no need for a U.S. plant "at this stage," noting that customers are "more desperate to get wafers than being too picky about where the location for production is"2

Analyst Outlook and Market Implications

New Street Research maintains a buy recommendation, arguing that the upward revision highlights underlying structural factors rather than cyclical ones4

4

. Emmanuel Mathot at Oddo BHF upgraded his rating to "outperform" from neutral, raising the price target from 150 to 175, citing impressive acceleration in demand and strong industrial adaptation capability4

4

. Berenberg analysts note that thanks to favorable pricing and operating leverage, the rise in activity should feed through strongly into profitability4

4

. Watch for how Soitec's contract strategy influences pricing power across semiconductor materials suppliers and whether other wafer manufacturers adopt similar deposit-based agreements to manage surging demand for AI infrastructure components.
