Fabrinet’s customer list says AI is everywhere

Not just an Nvidia side hustle

Fabrinet’s fiscal Q4 earnings came with a very useful plot twist: the optical manufacturing specialist is getting more of its growth from a cluster of tech heavyweights, not just one shiny AI kingpin.

CFO Csaba Vedres said four customers each accounted for at least 10% of total revenue in fiscal 2026: Cisco at 20%, Nvidia at 16%, Nokia at 11%, and Amazon at 11%. That’s a pretty loud hint that Fabrinet isn’t just riding the Nvidia wave — it’s surfacing across networking, cloud, communications and AI infrastructure all at once.

Why investors should care

This is the kind of disclosure Wall Street loves because it tells you where the demand is actually coming from. If you’re looking at Fabrinet as a contract manufacturer, this customer mix says the company is plugged into:

• data center interconnect and transceivers
• high-performance computing
• broader AI networking buildouts

In other words, the story is less “one customer saved the quarter” and more “the whole buffet is open.”

The bigger AI picture

Management sounded pretty amped about demand, saying it sees no end in sight from these markets. That’s encouraging, sure — but the real takeaway is diversification. If multiple tech giants are pulling on the same optical supply chain, Fabrinet gets to act like the plumber in a gold rush: not glamorous, but very much paid.

Big picture: if AI infrastructure spending keeps spreading across hyperscalers and networking gear, Fabrinet’s growth may have more staying power than the usual one-client wonder story.
