Fabrinet stock plunges 19%: Why investors are selling after Q4 beat
Fabrinet plunged 19.4% on August 18, sharply underperforming the broader market after investors reacted negatively to the company’s fiscal Q4 results and outlook. The stock had closed at $598.58 on Monday before the sell-off. (Sources: The Motley Fool, Investing.com)
Fabrinet reported Q4 fiscal 2026 non-GAAP EPS of $4.10, up 54.7% year over year and above the Zacks consensus estimate by 6.49%. Revenue reached roughly $1.316 billion, up 45% year over year, also topping expectations.
The problem was less about the quarter just reported and more about what investors expected next. Despite the earnings beat, investors focused on the company's outlook, the pace of its HPC ramp and concerns surrounding Nvidia-related sales. The reaction suggests expectations for AI infrastructure growth had become extremely demanding.
Fabrinet's underlying AI and data-center opportunity remains significant. Earlier in fiscal 2026, data center interconnect revenue grew 90% year over year, while demand for datacom products exceeded the company's ability to ship because of component constraints.
One key concern is Fabrinet's high-performance computing program. The company had previously indicated that its current HPC program could exceed $150 million in quarterly revenue once fully ramped, but the transition to a customer's latest-generation product has pushed that milestone out.
For the first quarter of fiscal 2027, Fabrinet is expected to deliver continued growth, with reported guidance of approximately $1.375 billion-$1.425 billion in revenue and $4.10-$4.25 in non-GAAP EPS. Yet investors appear to have wanted a stronger outlook given the stock's elevated expectations.
The longer-term story hasn't necessarily broken. Fabrinet is expanding manufacturing capacity and adding new customer programs, while its optical communications and data-center businesses remain major growth engines. Previous company commentary indicated several new programs should contribute more meaningfully during fiscal 2027.
Can Fabrinet's fundamentals catch up with the expectations embedded in its stock price? The August 18 sell-off highlights the risk facing high-growth AI infrastructure stocks: even strong earnings can trigger sharp declines when investors expect exceptional growth to continue accelerating.
