Applied Optoelectronics Is Up 205% This Year. Is It Too Late to Buy AAOI Stock Now?

Few hardware names have kept pace with Applied Optoelectronics (NASDAQ:AAOI) stock this year. Shares of the optical transceiver maker have outrun its closest industry rivals and the chip sector, driven by demand from data centers built for artificial intelligence (AI). Applied Optoelectronics stock is up 205% this year to $106.25.

Additionally, Applied Optoelectronics shares are up 8.7% in afternoon trading, extending its run this year. Lumentum (NASDAQ:LITE | LITE Price Prediction) stock, which rides the same data center optics buildout, is up 180% this year to $1,032.30. Notably, Coherent (NYSE:COHR) stock is up 71% this year to $316.05, a more measured climb for another supplier tied to the same theme.

For comparison, the iShares Semiconductor ETF (NASDAQ:SOXX) is up 91% this year. That fund holds chip designers and foundries, so its gain works as sector context for the optics move involving Applied Optoelectronics. The broad market has moved at a far slower pace, with the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) up 12% this year.

Record Revenue Meets a Capacity Ceiling

Applied Optoelectronics laid the groundwork for this run on its most recent quarterly earnings call, held in early August. On that call, the company reported its fifth consecutive quarter of record revenue and a return to profitability on a non-GAAP (generally accepted accounting principles) basis, a measure that excludes items such as stock-based compensation. Chief financial officer Stefan Murry stated that the company’s revenue rose 86% from a year earlier.

Thompson Lin, founder, chairman and chief executive of Applied Optoelectronics, described the bottleneck in direct terms: “Demand to support next-generation AI infrastructure remains so robust that our near-term revenue is bounded almost entirely by production capacity and key component availability.” Stefan Murry added that “we believe our 2026 revenue will be around $1.1 billion,” a level he tied to the company’s production capacity and supply chain. In management’s view, demand for the company’s products runs much larger than that.

One Rerating, Three Different Magnitudes

Applied Optoelectronics’ upside hinges on capacity: customers are already waiting, and the company is expanding its Texas manufacturing operations, including a new facility dedicated to high-speed transceivers, to close that gap.

However, that framing has been public since the August earnings call, so a buyer at $106.25 is paying for a capacity ramp the market has already heard about. Lumentum and Coherent carry a version of the same outlook, yet Applied Optoelectronics stock has run the most while its expansion is still being built. That leaves less room for error if new lines come up more slowly than planned.

Is It Too Late for Applied Optoelectronics?

The revenue ramp tied to the company’s new capacity is still ahead, so the move in Applied Optoelectronics stock may have further to run. What a buyer accepts at this level is execution risk, since management already describes demand as strong (we rounded up seven non-chipmaker suppliers riding the same AI infrastructure buildout in a free report here). The open question is how fast new production lines reach full output.

Whether the new Texas facility lifts output is worth tracking, and the next earnings call may help answer that. Any delay could weigh on Applied Optoelectronics stock, and Lumentum and Coherent could feel similar pressure if enthusiasm for optics cools.

Given that Applied Optoelectronics stock has climbed 205% this year while capacity is still under construction, moderate positions let investors stay with the demand story without depending on a smooth ramp.
