Fabrinet (FN) Beat Every Estimate. Its Stock Still Fell 11%
On August 18, 2026, Fabrinet (NYSE: FN ) shares fell 11% in premarket trading even after the data-center component supplier posted fiscal fourth-quarter adjusted earnings of $4.10 a share, up from $2.65 a year earlier and above Wall Street's $3.81 estimate. Revenue grew by 45% to $1.32 billion.
Fabrinet's own CEO says there's "no end in sight" to data-center demand, yet the stock fell anyway on the same day the company guided next quarter's numbers above expectations. Is this a sign that even genuinely strong AI-infrastructure earnings can't satisfy an overheated market, or are investors correctly spotting real cracks in specific parts of Fabrinet's business?
CEO Seamus Grady said, "There looks to be no end in sight to the demand from the customers," and Fabrinet (NYSE:FN) guided first-quarter profit of $4.10 to $4.25 a share, well above the $3.98 Wall Street guess. The high-performance computing business grew 11% from the prior quarter to $118 million. Both Barclays and J.P. Morgan raised their price targets to $739 and $695, even during the stock's drop. That guidance also lines up with what Nvidia itself reported for its most recent quarter, with Data Center revenue up by 75%. It simply means the broader AI infrastructure spending Fabrinet depends on is still genuinely accelerating at the top of the supply chain, even if Fabrinet's own relationship with that one customer has cooled.
Revenue from Nvidia, one of Fabrinet (NYSE:FN)'s biggest customers, actually fell 21% in fiscal 2026 to $742 million, according to B. Riley, which lowered its price target to $598 from $635, pointing to a "weak" data-communications segment. That segment's revenue dropped 1% from the prior quarter to $258 million, extending recent softness, and even though the high-performance computing business grew 11%, that wasn't enough to fully offset the weaker Nvidia tie. Shares had already gained entering the report, leaving little room for anything short of a flawless quarter. So even a genuinely strong beat triggered a sell-off once investors saw the customer risk underneath it.
Fabrinet's headline numbers were genuinely strong. Nonetheless, a declining Nvidia relationship and a weak datacom segment show the AI infrastructure boom isn't lifting every part of even its most exposed suppliers equally.
