Applied Optoelectronics books a record quarter and says AI optics demand will outrun its factories into 2027
The clearest read on how tight the AI networking supply chain has become this year did not come from a hyperscaler or a GPU vendor. It came from Applied Optoelectronics, the Texas-based maker of laser transceivers and cable-television optics, which reported second-quarter revenue of $191.9 million on August 6, up from $103.0 million in the same quarter of 2025, according to the company's results release.
The mix underneath that number is what matters for the AI trade. StockTitan's breakdown of the release put datacentre revenue at $107.7 million, more than double the $44.8 million booked a year earlier and roughly 56% of the quarterly total. The company's legacy cable-television business also grew, to $80.6 million from $56.0 million, helped by adoption of its 1.8 GHz products — an unusual position for a company that spent years being defined by CATV cyclicality and is now being repriced on optics for AI clusters.
Profitability tells a more complicated story. GAAP gross margin fell to 27.7% from 30.3% a year earlier, while the non-GAAP figure was 29.8% against 30.4%, per the results release. Operating expenses climbed to $77.9 million from $47.1 million as the company scaled up, StockTitan reported. The result was a GAAP net loss of $22.8 million, or $(0.28) a share, alongside non-GAAP net income of $5.5 million, or $0.06 a diluted share — a swing from a non-GAAP loss of $8.8 million in the year-ago quarter.
Management's guidance was the headline that moved the stock. For the third quarter, Applied Optoelectronics pointed to revenue of $255 million to $290 million, with non-GAAP gross margin of 29% to 30.5% and non-GAAP net income of $10.1 million to $24.0 million. That is a substantial step up from the June quarter, and it implies the company expects the datacentre ramp to accelerate rather than plateau.
Chief executive Thompson Lin framed the constraint as physical rather than commercial. He said the company forecasts demand continuing to outpace production capacity through the middle of 2027, and noted that volumes of its 800G products more than doubled sequentially in the quarter. In an industry where the bottleneck has repeatedly migrated — from GPUs to memory to power to interconnect — a supplier publicly saying it cannot build fast enough for another four quarters is a meaningful data point about where the strain currently sits.
The balance sheet gives the company room to chase that demand. Applied Optoelectronics reported $508.8 million in cash at June 30, 2026, a cushion that matters given how capital-intensive optical component manufacturing is and how quickly speed transitions can strand inventory.
Investors responded quickly. StockTitan noted the shares gained 9.19% on August 7, more than the stock's historical average earnings-day move. The stock closed at $134.33 on August 11, up 1.14% on the session, with a market capitalisation of about $11.36 billion and trailing twelve-month revenue of $595.97 million, according to StockAnalysis. That same page shows a 52-week range running from $18.50 to $233.67 — a spread that captures both how violently this name has re-rated and how little consensus there is on what it is worth.
The open questions from here are straightforward. Whether GAAP gross margin recovers as the capacity investments season, whether the third-quarter range is met at the top or the bottom, and whether the 800G ramp carries into 1.6T without a margin air pocket will determine how much of the re-rating holds. For now, the company has done something few AI-adjacent small and mid caps managed this quarter: it produced a non-GAAP profit and told the market its problem is making enough product, not selling it.
