Soitec Secures Multi-Year AI Photonics Wafer Contracts, Raises Photonics SOI Revenue Target to Over $200 Million

How do these contracts actually "lock in" demand?
The deals use a deposit-plus-fixed-pricing mechanism: customers pay deposits up front; if they take the agreed volume, deposits are fully refunded; if they fall short, deposits are forfeited; if they exceed the volume, repricing talks are triggered.
This means → customers put real money on the table before a single wafer ships — both sides share the risk, with Soitec locking revenue and customers locking supply.
Contracts also require customers to share inventory data, preventing firms from over-booking capacity just to keep wafers away from rivals.
Remont says roughly 80% of capacity-reservation agreements will be signed within one to two weeks, with the rest closing within a month.
"Over $200 million" — why does that number matter?
Last month Soitec told investors that photonic SOI — a chip substrate material designed specifically for carrying optical signals — would more than double from just over $100 million this fiscal year, but left unclear whether that figure was a base case or a ceiling.
This time, the CEO was explicit: over $200 million is "absolutely a floor." In plain terms = last month the message was "we could reach $200 million"; this month it is "$200 million is just the starting point."
This reflects a shift from forecast-based guidance to contract-backed certainty, now that deals are landing in bulk.
What gives Soitec the power to lock customers in?
UBS estimates Soitec holds roughly 95% of the silicon-photonics substrate market — it is virtually the sole supplier.
This means → customers have no real alternative, and pricing power sits naturally with Soitec; the deposit-and-lock-price terms work because supply is extremely concentrated.
The demand driver is equally clear: hyperscale cloud providers are replacing copper cables with optical interconnects inside AI infrastructure, because copper is hitting limits on power consumption and performance. Soitec's stock has risen nearly threefold this year.
Is there enough capacity? What does the expansion plan look like?
The CEO says Soitec will not need a new factory until around 2029. Before then, three levers are available:
Lever one: reallocating output across shared idle facilities — including a French site originally built for silicon-carbide production (written down by €41 million last year, now repurposable). Lever two: adding equipment inside existing cleanrooms. Together these "cover this year and next."
Lever three: an as-yet-unequipped building in Singapore that could come online in 6–12 months if needed. Soitec also completed customer qualification at its Singapore plant about five months ago, meaning production no longer depends on a single country.
Asked whether a U.S. factory is necessary, Remont was blunt: "Customers' desire to get wafers far outweighs any pickiness about where they are made."
What can't a lock-price contract lock?
Multi-year lock-price deals sharply raise revenue visibility, but they have not fully capped the upside: volumes exceeding the agreed amount trigger repricing negotiations.
In plain terms = if demand keeps overshooting, Soitec can negotiate higher prices on top of the guaranteed floor.
Whether this structure holds beyond 2027, however, depends on the staying power of hyperscaler capital spending — if AI infrastructure investment slows, the "floor" itself becomes the ceiling.
