Applied Optoelectronics is a hyper-growth optical components maker (86% YoY revenue growth) with a large analyst upside, but it burns cash, depends on a few customers and sits 70% off its high, making it speculative.

About Applied Optoelectronics, Inc.
About Applied Optoelectronics, Inc.
Digicomm and Microsoft together represented 81.9% of Applied Optoelectronics' $455.7 million in 2025 revenue, with Digicomm's share rising from 34.1% in 2024 to 53.1%. The top ten customers accounted for 96.6% of 2025 revenue. CATV generated 53.8% and the internet data center market 42.9% of 2025 revenue; revenue nearly doubled from $249.4 million in 2024.
The company sells fiber-optic products at three integration levels — components, modules, and turn-key equipment — to CATV equipment vendors, MSOs directly under the Quantum Bandwidth brand, and hyperscale data center operators. In the CATV market, DOCSIS 4.0 equipment upgrades drove nearly all 2025 CATV product sales. In data center, demand for 800 Gbps and above transceivers was propelled by AI workloads from hyperscale operators. Applied Optoelectronics vertically integrates laser fabrication using both MBE and MOCVD processes — a capability the company believes is unique in high-volume communications laser production. The high fixed cost base associated with this vertical integration means gross margin is sensitive to volume shifts; gross margin was 30.0% in 2025 versus 24.8% in 2024 as revenue rose sharply.
Show full overview
Digicomm represented 53.1% of Applied Optoelectronics' revenue in 2025, a concentration that rose from 11.3% in 2023, creating an outsized dependency on a single CATV market customer. The company does not maintain long-term contracts, relying instead on recurring purchase orders that customers may increase, decrease, cancel or delay without significant penalty per the 10-K. The top ten customers together represented 96.6% of 2025 revenue, leaving virtually no revenue base outside a handful of named accounts.
