AXT Inc's stock soared 5.07% in pre-market trading, marking a significant rebound from recent declines. The semiconductor equipment company's shares have been volatile, with this pre-market surge following two consecutive trading sessions of sharp declines exceeding 5% each.

The rebound appears driven by several fundamental factors. AXT Inc reported better-than-expected Q1 earnings with revenue growing 38.7% year-over-year and losses narrowing substantially. Additionally, long-term demand expectations for AI optical communications remain intact, with orders for the company's indium phosphide (InP) substrates — critical base material for high-speed 800G/1.6T optical modules — reportedly booked through 2027.

Following the recent profit-taking selloff that pulled the stock back from its all-time high, investors appear to be returning to the stock based on unchanged fundamental support and attractive valuation after the sharp declines. The combination of strong earnings performance and sustained demand in the AI optical communications sector has provided the catalyst for this pre-market rebound.
