Applied Optoelectronics, Inc. (NASDAQ: AAOI) closed at $46.89 (down -20.89% on the day) following its Q3 2026 earnings report released on November 5, 2026, and dropped further in after-hours trading.
Key Financial & Earnings Highlights (Q3 2026)
• Revenue: Reached $269.9 million, beating the analyst consensus of $268.11 million and surging 128% year-over-year (representing the sixth consecutive quarter of record revenue).
• Adjusted EPS: Reported $0.17 per share, beating the expected $0.14 per share.
• GAAP Net Income: Returned to profitability at $6.3 million ($0.07 per share), a sharp turnaround from a net loss of $17.9 million in Q3 2025.
• Gross Margin: GAAP gross margin stood at 28.2% (up from 28.0% a year ago).
Why the Stock Tumbled
Despite beating Q3 estimates on both top and bottom lines, AAOI shares plummeted ~10% to over 20% due to a disappointing outlook:
• Q4 2026 Revenue Guidance: Projected at $385 million to $420 million (midpoint $402.5 million), which missed the Wall Street consensus of $427.26 million.
• Q4 Adjusted EPS Guidance: Guided to $0.48 to $0.63 per share (midpoint $0.56), which aligned closely with expectations, failing to offset the top-line guidance miss.
• Capacity & Infrastructure Delays: Management noted that planned 2027 U.S. manufacturing capacity expansions in Sugar Land, Texas, are facing delays due to electrical power availability and construction hurdles.
Growth Drivers & Risks
• Bullish Catalysts:
• Scaling production of 800G and 1.6T optical transceivers riding on high-bandwidth AI infrastructure demand.
• Secured a multi-year strategic agreement with a Tier 1 hyperscale datacenter customer, improving long-term visibility.
• Continued software and hardware footprint expansion (such as QuantumLink remote network management with Spectrum).
• Key Risks:
• Extreme customer concentration (heavy reliance on major hyperscalers and key accounts like Microsoft and Digicom).
• Cyclicality and sentiment swings regarding AI capital expenditure budgets by major tech companies.
• Dilution and balance sheet pressures, including prior at-the-market equity programs and outstanding warrants.
