Key Highlights

  • Record Revenue for a sixth consecutive quarter, according to management.
  • GAAP Net Income of $6.3 million, compared with a net loss of $17.9 million a year earlier.
  • GAAP gross Margin of 28.2 percent, up from 28.0 percent in the third quarter of 2025.
  • Fourth quarter 2026 revenue is expected between $385 million and $420 million.

Applied Optoelectronics, Inc. (NASDAQ:AAOI) reported results for the third quarter ended September 30, 2026, a period in which the Sugar Land, Texas company said it returned to GAAP profitability. GAAP net income reached $6.3 million, or $0.07 per basic share, compared with a net loss of $17.9 million, or $0.28 per share, a year earlier. The company described the quarter as its sixth consecutive period of record revenue, with Demand concentrated in optical connectivity products used in artificial intelligence datacenters and cable television networks.

Revenue Momentum and Product Focus

Management pointed to Manufacturing progress for 800G and 1.6T optical products as a central driver of recent growth. Those product generations support the higher data transfer speeds that AI infrastructure requires, and the company said it has been scaling output to meet that demand. The release also described a multi-year strategic agreement with a Tier 1 hyperscale datacenter customer, which management said should improve long-term visibility into orders.

The company's datacenter and cable television businesses both contributed to the quarter's results, according to management commentary. Total manufacturing equipment capacity was described as approaching 330,000 units per month. The CFO also said the 2027 capacity expansion plan in the United States is expected to take longer than planned, citing delays in obtaining electrical power and other construction issues.

The company's capacity figure of approximately 330,000 units per month gives a sense of current output scale. The timetable for the 2027 US expansion, which management said will take longer than expected, means that additional capacity arrives later than initially planned, so the company's ability to convert existing capacity into shipments will shape how much of the guided growth is realized.

Margins and Profitability

GAAP gross margin was 28.2 percent, compared with 28.0 percent in the third quarter of 2025 and 27.7 percent in the second quarter of 2026. Non-GAAP gross margin, however, was 28.7 percent, below the 31.0 percent recorded a year earlier and the 29.8 percent of the prior quarter. The difference between the two measures and the year-over-year pattern shows that margin movement depends on which cost items are included.

Scaling production has not yet produced large margin gains. Gross margin moved only modestly over the year despite faster revenue growth and expanded manufacturing capacity, which indicates that Volume gains are being offset by mix, input costs and the build-out of new facilities.

Non-GAAP net income was $14.8 million, or $0.17 per diluted share, compared with a non-GAAP net loss of $5.4 million a year earlier and non-GAAP net income of $5.5 million, or $0.06 per diluted share, in the second quarter. Over the same sequential period, GAAP net income improved by more than non-GAAP net income, which reflects the items the company excludes from its non-GAAP measure.

Fourth Quarter Outlook and Capacity Plans

For the fourth quarter of 2026, the company expects revenue between $385 million and $420 million. Founder and CEO Thompson Lin said the company believes demand for AI-related optical technologies is accelerating.

The capacity build-out remains a central planning item. Management acknowledged that power availability and construction timing could push completion of the 2027 US expansion beyond earlier assumptions, a Factor that could affect how quickly the company can meet further demand.

The midpoint of the $385 million to $420 million fourth quarter range is $402.5 million. The range is wide, so the reported outcome could fall anywhere within it depending on shipment timing and customer demand.

Final Takeaways

The third quarter shows Applied Optoelectronics returning to GAAP net income while continuing to grow revenue in its AI-linked product lines. Gross margin remained in a narrow range, and the non-GAAP margin declined from a year earlier. The fourth quarter guidance and the progress of the US capacity expansion will show whether the revenue trend and profitability move together in the coming period.
