Applied Optoelectronics returns to profit but warns AI demand will exceed capacity through 2027

Applied Optoelectronics returned to profit in its third-quarter 2026 results, earning $6.3 million on record sales of $269.9 million. But its next stage of growth is running into production limits: management says demand for high-speed data-center optical modules will exceed what it can manufacture throughout 2027, even as it builds more capacity.

The November 5 earnings release showed revenue rising about 128% from $118.6 million a year earlier. CEO Thompson Lin called it the sixth consecutive quarter of record revenue. The company also moved back into profitability under generally accepted accounting principles, or GAAP, after a loss in the same period last year.

Lin said AI revenue reached $47.5 million, nearly quadrupling from the previous quarter. That is a narrower measure than company-wide sales: the full revenue total should not be read as AI revenue. The production warning concerns the company's 800G and 1.6T transceivers—high-speed optical modules used in data centers.

A customer moves faster than the supply chain

On the earnings call, CFO Stefan Murry tied the near-term shortfall to a large customer switching from 800G to 1.6T products faster than expected. That transition left Applied Optoelectronics short of materials for the newer modules, according to 24/7 Wall St.'s account of the call. Stronger demand did not translate directly into more shippable products.

Lin put the gap in dollar terms: the company held about $450 million in 1.6T orders, but expected to ship only $50 million to $70 million of them in the fourth quarter. Those figures distinguish customer orders from the smaller amount management believes it can deliver during the period.

The resulting fourth-quarter revenue forecast is $385 million to $420 million, including $270 million to $300 million from data centers. Even the top of the company-wide range falls below the $427.26 million analyst consensus cited by 24/7 Wall St., despite management's forecast of roughly 200% annual growth at the midpoint.

A large contract, not guaranteed revenue

The customer transition also puts an October agreement into focus. An unnamed existing hyperscale customer agreed to buy at least 10% of its 1.6T transceiver needs from Applied Optoelectronics for a period running from June 2026 through May 2029. The arrangement has conditions, including the supplier's ability to provide the products.

Management estimates that agreement could generate $1 billion to $1.5 billion in revenue. It is not a guaranteed dollar commitment: the outcome could vary significantly with the customer's actual demand. Prices are fixed, with some reductions built into the term, while the customer has committed no capital toward manufacturing.

The factory timetable moves back

Applied Optoelectronics is increasing output, but has changed the pace of its expansion. Monthly capacity is nearing 330,000 units, compared with about 200,000 at the end of the second quarter. Its revised targets put less capacity in place this year, followed by a larger manufacturing base at the end of 2027.

Revised monthly capacity targets

End of 2026

650,000→More than 500,000

units per month

The company lowered its year-end target from 650,000 to more than 500,000 units a month.

End of 2027

930,000→More than 1 million

units per month

The following year's target increased from 930,000 to more than 1 million units a month.

Phase 1 of its Sugar Land, Texas, factory is scheduled to begin operating in December 2026. Phase 2 has slipped about seven months, mainly because of the time needed to secure electrical power. That delay pushes the company's $471 million monthly revenue run-rate goal toward the end of 2027—a future operating target, not revenue already earned.
