Shares of optical communications company Applied Optoelectronics (AAOI.US) experienced a significant rise on Friday, climbing more than 38% to $74.49 at the time of reporting. The surge followed the company's first-quarter performance guidance, which exceeded market expectations. Applied Optoelectronics raised its revenue target for 2026 to over $1 billion and projected revenue of approximately $4 billion for 2027. Although the growth in 800G revenue has been delayed until the second quarter of 2026 due to firmware customization issues with Amazon (AMZN.US), analysts believe that data center demand continues to provide support. Over the past year, the stock has accumulated a gain of 123%, and the company's current market capitalization stands at around $4 billion.
