Not an AI company.
It sells AI its
plumbing.
Every AI data center needs optical transceivers to move data. Applied Optoelectronics makes them.

✦ The bottom line
Applied Optoelectronics sold $456M in 2025, and the most recent quarter grew ~51% year-over-year. The driver: AI data centers need enormous numbers of optical transceivers — the devices that shuttle data between servers and chips at light speed — and AAOI makes them. It's a 'picks and shovels' play on the AI buildout.

The 'picks and shovels' idea
In a gold rush, the people who reliably made money weren't the prospectors — they were the ones selling picks, shovels, and jeans. Investing in infrastructure suppliers instead of betting on which AI company wins is the modern version.
AAOI sells optical transceivers — pluggable modules that convert electrical signals to light and back, so data can race through fiber between machines. As AI data centers multiply and get faster (400G, 800G and beyond), they need more and faster transceivers.

Revenue / picks-and-shovels
A supplier can grow with the whole industry instead of one winner — but it's also exposed to the industry's *cycles* and to the *power* of a few huge buyers, which is the rest of this story.
Revenue · most recent quarter vs. a year earlier
Q1 2026 revenue of $151M, up from $100M a year earlier — pulled along by data-center demand for higher-speed optical transceivers.

Total revenue · fiscal year 2025
Growing as the AI buildout accelerates. Alongside data center, AAOI also sells into cable-broadband and telecom — but data center is the growth engine.
