U.S. Optical Tech Giant's Stock Soars 57% on Expansion
Recently, Applied Optoelectronics, a U.S.-based optical communication technology company, released its fiscal Q4 2025 results, and the report, along with its guidance for the next quarter and full year, exceeded market expectations. Coupled with the announcement of an expansion plan, the company's stock surged 56.88% on February 27, closing at $84.23 per share—a record high since August 3, 2017. Since the start of the year, its shares have climbed 141.62%.
The Q4 revenue reached $134.3 million, a 34% increase year-over-year and above analysts' forecast of $132.3 million. Adjusted non-GAAP earnings per share showed a slight loss of $0.01, improving from a $0.02 loss in the prior year and beating analysts' expectation of a $0.11 loss. Looking ahead to Q1 2026, the company expects revenue between $150 million and $165 million, surpassing the prior analyst estimate of $145.7 million.
Management noted that revenue from 800G modules fell below initial projections of $4–8 million due to ongoing firmware optimization. While exact Q4 figures were not disclosed, executives confirmed that 800G module revenue was below $4 million, with some sales deferred to Q1. Despite this shortfall, strong demand for 400G modules from the same customer compensated for the gap. Applied Optoelectronics anticipates robust 400G demand to continue, with 800G modules becoming a major revenue driver starting in Q2. Executives projected that 800G module sales could exceed $25 million in the second quarter, with potential for even higher revenue depending on production capacity.
The company also highlighted that another existing hyperscale cloud client has signaled plans to begin ordering 800G products soon, while a new hyperscale customer has recently engaged in discussions around 800G and 1.6T product validation. To support this growth, Applied Optoelectronics has started expanding production at its Texas and Taiwan facilities, targeting monthly output of over 500,000 units for 800G and 1.6T modules by the end of 2026. Despite current capacity limits, the company expects full-year 2026 revenue to exceed $1 billion, with non-GAAP operating income surpassing $120 million.
Raymond James analyst Simon Leopold commented that, based on current supply-demand projections, the company's data center monthly revenue could reach $378 million by mid-2027, translating to an annualized $4.5 billion—a notably ambitious target.
