Applied Optoelectronics Delivers Record Revenue and Margin Gains as Manufacturing Expansion Fuels Outlook
Strong Revenue and Margin Improvements Highlight Best Year in Company History
Applied Optoelectronics, Inc. (NASDAQ: AAOI) has turned in its strongest year to date, announcing a sharp surge in both quarterly and annual revenues for 2025. The company posted fourth-quarter revenue of $134.3 million, up from $100.3 million a year earlier, while full-year 2025 revenue reached $455.7 million—an 83% jump from 2024.
Operationally, margins have also strengthened. The Q4 GAAP gross margin improved to 31.2% (from 28.7% in Q4 2024), and full-year margins climbed to 30.0% versus 24.8% last year. On a non-GAAP basis, the full-year gross margin hit 30.9%, indicating underlying profitability is improving alongside top-line momentum.
Key Drivers: Broad-Based Demand and Scaling Up for Datacenter Growth
Leadership credited the company’s record quarter and year to rising demand across both the CATV and the datacenter segment—critical infrastructure sectors as digital transformation deepens globally. Investments to expand manufacturing capacity made notable headway in Q4, positioning AAOI to ramp up new, next-generation optoelectronic products for the datacenter market in 2026 and beyond.
"We have considerable momentum entering 2026, and we believe we are well positioned to accelerate our growth this year," said Dr. Thompson Lin, founder and CEO. Dr. Stefan Murry, CFO and CSO, added that these capital investments are a foundation for both volume growth and improved operational strength going forward.
