French semiconductor materials manufacturer Soitec is locking customers into multi-year supply agreements with deposits and fixed pricing as surging demand for AI-driven silicon photonics wafers pushes photonics-SOI revenue past $200 million. The company holds a 95% market share in wafers critical for AI data center optics.

Soitec Capitalizes on Surging AI Wafer Demand with Strategic Contracts

Soitec, a French semiconductor materials manufacturer, is securing its position in the booming AI infrastructure market by locking customers into multi-year supply agreements for silicon photonics wafers. Chief Executive Laurent Remont told Reuters that the company is "using the current situation to find the right balance between the value we bring and the price we can ask."

The strategic move comes as AI wafer demand has driven the company's stock to nearly quadruple this year, reflecting investor confidence in its market dominance.

Photonics-SOI Revenue Exceeds $200 Million Floor

The company revealed that photonics-SOI revenue would more than double this financial year from slightly above $100 million. Remont now characterizes the $200 million mark as "absolutely a floor," signaling expectations for substantially higher revenues.

This dramatic growth reflects the surging demand for AI data center optics, where hyperscalers increasingly rely on optical connections for AI infrastructure instead of copper links, which face power and performance constraints.

2

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

3

This near-monopoly position enables the company to dictate favorable terms as demand for silicon photonics substrates accelerates.

Multi-Year Supply Agreements Feature Deposits and Fixed Pricing

Around 80% of Soitec's capacity reservation agreements with more than 10 photonics customers should be signed within a week or two, with the remainder expected within a month, according to Laurent Remont.

These contracts establish fixed pricing and require cash deposits tied to committed demand, creating a binding commitment structure.

Under the agreement terms, customers who meet their committed volume receive their deposits back, while those falling short forfeit the funds. Volumes exceeding agreed levels trigger new pricing discussions.

"That's a way for us to have our customer with skin in the game," Remont explained.

Customers must also share inventory data, a requirement designed to prevent companies from over-ordering capacity to keep wafers away from competitors.

The cash deposits will arrive in stages as customers ramp production, providing Soitec with predictable revenue streams.

Capacity Expansion Strategy Delays New Fab Until 2029

Soitec does not expect to need a new plant until around 2029, as the company pursues three capacity expansion levers.

1

The first two approaches involve shifting output between businesses using shared underutilized facilities and installing additional tools in existing cleanroom space. "With that we will cover easily this year and next year," Remont stated.

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 year.

1

Until five months ago, Soitec produced photonics-SOI only in France, but has since qualified customers at its Singapore site.

2

A third lever involves an unequipped building in Singapore that could add capacity within six to 12 months if required. "We can increase quickly without building a completely new fab, just equipping a building," Remont noted.

1

He sees no need for a U.S. plant "at this stage," observing that customers are "more desperate to get wafers than being too picky about where the location for production is."

Market Response and Future Outlook

Soitec shares climbed approximately 6% following the Reuters report on the multi-year supply agreements.

3

The positive market response reflects investor confidence in the company's ability to capitalize on optical connections for AI infrastructure, a market segment experiencing rapid expansion as hyperscalers build out data centers optimized for artificial intelligence workloads.

The strategic positioning suggests Soitec will maintain pricing power through 2029 while competitors face significant barriers to entry given the company's technological lead and established customer relationships. Watch for how competitors respond to Soitec's market dominance and whether new entrants can challenge its 95% market share in silicon photonics wafers as AI infrastructure demands continue accelerating.
