AXT Inc (AXTI) experienced a sharp decline of 30.47% in after-hours trading following the release of its Q4 2025 revenue guidance. The company expects revenue to fall between $22.5 million and $23.5 million, which appears to have disappointed investors.

The significant drop reflects market concerns over the company's financial performance, as the guidance suggests weaker-than-anticipated results. The announcement was accompanied by the scheduling of an earnings call for February 19, 2026, where further details will be discussed.
