Applied Optoelectronics sees AI demand outrun capacity through 2027

By Elena Vasquez

After the close on Thursday, November 5, 2026, CFO Stefan Murry said Applied Optoelectronics’ demand for 800G and 1.6T data center transceivers will “exceed our production capacity throughout 2027.”

The warning came on the company’s third-quarter earnings call. 24/7 Wall St. reported that Applied Optoelectronics (NASDAQ:AAOI) already has more orders than it can build.

Here, “AI demand” means demand for those high-speed optical modules. 24/7 Wall St. linked the optical shortage to the wider AI data-center buildout, where power and cooling face similar constraints.

Coherent (NYSE:COHR), Lumentum (NASDAQ:LITE), InnoLight and Eoptolink compete for the same orders, according to 24/7 Wall St. The report places AAOI’s production problem inside a broader supply chain for new AI capacity.

24/7 Wall St. says the investor question is no longer whether demand exists. It is how quickly constrained factories can convert that demand into revenue.

What did the third quarter show?

Applied Optoelectronics reported:

• Revenue of $269.9 million, about 128% above the $118.6 million recorded a year earlier.
• GAAP net income of $6.3 million.
• Non-GAAP earnings per share of $0.17 and a non-GAAP gross margin of 28.7%.

CEO Thompson Lin called it the sixth straight quarter of record revenue. He said AI revenue reached $47.5 million and nearly quadrupled from the prior quarter.

In 24/7 Wall St.’s reading, the combination of 128% revenue growth, six record quarters and rapidly rising AI revenue shows demand arriving faster than usable production. That makes the capacity warning a test of execution, not sales.

What does the hyperscaler agreement guarantee?

Applied Optoelectronics signed the agreement in October with an existing Tier 1 hyperscale customer that it did not name. The customer will buy at least 10% of its 1.6T transceiver needs from AOI between June 2026 and May 2029.

The purchase is conditional, including on AOI’s ability to supply. 24/7 Wall St. said that condition matters because the agreement underpins management’s revenue estimate while the company lacks 1.6T materials.

Management expects $1 billion to $1.5 billion in revenue from the deal, but 24/7 Wall St. called that an estimate that could vary significantly with the customer’s actual demand. Prices are fixed, with some cuts built in over the term. The customer committed no capital, so AOI pays for the factories and loses out if market prices rise.

The agreement’s $1 billion-to-$1.5 billion estimate depends on actual demand, while fixed prices, embedded cuts and the absence of customer capital leave AOI carrying much of the financial risk. According to 24/7 Wall St., the contract offers volume rather than pricing protection.

In 24/7 Wall St.’s analysis, the deal’s size depends on the same two variables behind the fourth-quarter miss: customer demand and AOI’s ability to deliver 1.6T products.

Can new Texas capacity catch up?

Applied Optoelectronics said monthly capacity is nearing 330,000 units. That compares with about 200,000 units at the end of the second quarter.

The company then changed its targets in opposite directions:

• End-of-2026 capacity: more than 500,000 units a month, down from 650,000.
• End-of-2027 capacity: more than 1 million units a month, up from 930,000.

24/7 Wall St. said the revised schedule slows revenue growth at first but points to a higher monthly run rate by the end of 2027. The company is accepting a slower near-term ramp in exchange for more capacity later.

Management said Phase 1 of the Sugar Land, Texas plant will start operating in December 2026. Phase 2 has slipped about seven months, mainly because securing electrical power took longer. 24/7 Wall St. said that delay pushes a $471 million monthly revenue run-rate goal toward the end of 2027.

Why did fourth-quarter guidance miss consensus?

Applied Optoelectronics guided to:

• Fourth-quarter revenue of $385 million to $420 million, about 200% growth at the midpoint.
• Data-center revenue of $270 million to $300 million.
• Non-GAAP EPS of $0.48 to $0.63.

The $402.5 million revenue midpoint sits below the $427.26 million consensus estimate. The EPS range brackets the 56-cent estimate.

Murry said the shortfall came from the deal customer moving from 800G to 1.6T faster than expected, leaving AOI short of 1.6T materials. Lin said the company held about $450 million in 1.6T orders but could ship only $50 million to $70 million of them in the fourth quarter.

Management has more 1.6T demand than it can serve, a shortage Lin said extends across the industry and could leave suppliers meeting less than 80% of customer demand. 24/7 Wall St. noted that the warning arrives after AOI completed a $600 million stock sale in October.

24/7 Wall St. framed the central tension: record revenue can coexist with quarterly guidance below consensus when the limiting factor is components rather than customer demand.

How did investors and analysts react?

Before the report, AAOI stock fell 20.89% to $46.89 on Thursday during a sector-wide selloff. On Friday, November 6, it gained 6.87% to $50.11 after the earnings report.

That close remained about 79% below the 52-week high of $233.67. Coherent rose 13.57% and Lumentum gained 5.63% on Friday.

Friday’s analyst revisions produced a wider split:

• B. Riley cut its target to $45 from $92, below AAOI’s $50.11 close.
• Rosenblatt set its target at $115, down from $220.
• Raymond James set its target at $165, down from $178.

The first target implied a lower share price, while the other two remained far above the market price. 24/7 Wall St. said the bullish case around $50.11 depends on the fourth-quarter shortfall coming from missing parts for booked orders and on the higher 2027 capacity target.

The source listed three main risks: a GAAP operating loss, more dilution and fixed contract prices. It also framed the central question as whether the capacity limit is temporary or the reason the growth story keeps disappointing.

What happens next?

Management is scheduled to present at the Raymond James TMT and Consumer Conference on December 9, 2026. The next earnings call is February 25, 2027.

24/7 Wall St. set two numerical warning signs. If fourth-quarter revenue comes in below $385 million, or the stock closes under $45, the source said the constraint has likely become the bigger problem and the bull case weakens.

The next test is whether AOI can turn roughly $450 million in booked 1.6T orders into shipments while Phase 1 starts on time and power delays stop Phase 2 from slipping again. Those shipments will show whether Thursday’s record demand becomes revenue or remains an order-book bottleneck.
