Applied Optoelectronics (AAOI) experienced a significant intraday surge, with its stock price soaring 8.55% during Monday's trading session.

The sharp rebound appears driven by a key fundamental development. The company's Xinbei factory has received production approval from a hyperscale customer for its 800G optical transceiver capacity. This milestone is significant, with monthly output expected to exceed 100,000 units by year-end, representing an annualized capacity of over 1.2 million units.

This positive news provided strong support for the stock, helping it recover from recent selling pressure that had been fueled by concerns over a first-quarter earnings miss and a planned equity financing. The approval signals growing demand and execution capability in the high-speed optical module market, contributing to the notable intraday price movement.
