Soitec (
$SOI /
$SLOIF) just reminded the market why photonics remains one of the most important AI infrastructure themes.
Q1 revenue beat expectations, and Q2 guidance came in at 30%+ growth versus 4% consensus, sending the stock up 22%.
The biggest takeaway:
Photonics-SOI sales doubled YoY and now account for more than half of its Edge & Cloud AI business.
According to BofA, Soitec's engineered wafers are now becoming essential in AI data centers as networking moves beyond 800G, with companies like:
$AAOI
$COHR
positioned further downstream in the same optical ecosystem.
Even more bullish:
• Singapore 300mm fab qualified ahead of schedule
• 10+ customers have reserved capacity through FY2027+
• CPO requires several times more Photonics-SOI wafer area than traditional pluggables
While margins are still recovering due to fab utilization, demand continues to strengthen.
The AI networking buildout isn't slowing—it's becoming increasingly optical.
