Fabrinet's 45% revenue surge masks a 30bps gross margin drop and rising customer concentration. The Q4 beat is real, but the Q&A reveals dodges on pricing and supply. Can the optical king defend its premium valuation, or is the hyperscaler squeezing the life out of it? Read the full breakdown.
The Lede & The Real Story
Fabrinet’s fiscal fourth-quarter report was a masterpiece of optics — literally. The company, a contract manufacturer for optical and electronic components, posted revenue of $1.316 billion, up 45% year-over-year, and non-GAAP EPS of $4.10, both above the high end of guidance. CEO Seamus Grady called it an “outstanding fourth quarter” and promised “an even stronger fiscal 2027.” The stock jumped 4.97% in after-hours trading. But beneath the headline numbers, a more uncomfortable story is unfolding: the company’s core optical segment — the engine of its growth — is showing signs of margin compression and customer concentration that management is reluctant to address directly.
In the prior quarter (Q3 FY2026), revenue was $1.214 billion (up 39% YoY) and EPS was $3.72. The sequential revenue increase of 8.4% is solid, but the EPS jump of 10.2% is less impressive when you consider that the company’s non-GAAP operating margin actually declined sequentially — from 17.8% in Q3 to 17.5% in Q4. That’s a red flag: revenue is growing faster than profit, and management’s explanation — “product mix” — is a euphemism for lower-margin datacom products dominating the mix.
The real story is that Fabrinet is becoming a one-trick pony, increasingly reliant on a single hyperscale customer for its datacom revenue, while its traditional telecom business — once a stable cash cow — is stagnating. The company’s own investor presentation shows that datacom revenue grew 78% YoY in Q4, but telecom grew only 12%. That divergence is not a sign of health; it’s a concentration risk that management is downplaying.
