Shares of Fabrinet plunged 8.6% to $546.88 in Tuesday trading, erasing a 5% rally from the prior session, after investors looked past a blowout earnings report and zeroed in on a cash-flow hole created by aggressive factory expansion. The Thailand-based optical manufacturer posted record Q4 revenue of $1.316 billion, up 45% year-over-year, with non-GAAP EPS of $4.10 — both above guidance. The message from Wall Street: beating numbers isn't enough when the bill for growth is this steep.

  • Revenue Crushed Estimates, but Cash Practically Vanished

Fabrinet generated just $256.7 million in operating cash flow for fiscal 2026, down from $328.4 million a year earlier, even as profits grew. Capital spending more than doubled to $252.5 million.

The result: full-year free cash flow — the money left after building factories — collapsed from $207.3 million to just $4.2 million.

Q4 alone was cash-flow negative, with $91.9 million in capital spending overwhelming $55 million in operating cash. For a stock that traded near 59 times earnings before this report, that's a jarring reality check.

  • Next-Quarter Guidance Beat Consensus but Couldn't Stop the Selling

Fabrinet guided Q1 fiscal 2027 adjusted EPS of $4.10–$4.25, above the $3.96 consensus, with revenue of $1.375–$1.425 billion versus the $1.321 billion estimate.

The company is building new facilities in Thailand and Santa Clara, targeting revenue capacity of $12.5–$14 billion over the coming years. That's a bet the AI infrastructure wave will last — but it means heavy spending won't ease soon.

  • Customer Concentration Adds a Layer of Risk

Four customers — Cisco (20%), NVIDIA (16%), Nokia (11%), and Amazon (11%) — accounted for the majority of fiscal 2026 revenue.

Management acknowledged that component supply constraints could limit near-term growth. Any shift in orders from a single hyperscaler could ripple through earnings disproportionately.

  • Today's AI Summit Puts Management on the Spot

Fabrinet's fireside chat at the Rosenblatt AI Technology Summit is scheduled for 1:00 p.m. EDT today. Investors will be listening for clarity on when capital spending peaks and free cash flow recovers — the one question last night's earnings call left unanswered.
