On August 18, AXT Inc fell 5.18% in after-hours trading, trading at $90.81/share, with turnover of $15.254 million. The decline came after the stock surged approximately 14.86% during regular trading earlier in the session, suggesting profit-taking pressures emerged overnight.

The pullback coincided with broad weakness across the semiconductor equipment sector. Among peers, Applied Materials fell 2.5%, Lam Research fell 2.02%, Teradyne fell 1.75%, ASML fell 1.37%, and KLA Corporation fell 1.2%. AXT's decline notably exceeded that of its sector peers, likely reflecting heightened volatility following its sharp intraday gains driven by continued market digestion of its Q2 earnings inflection point and indium phosphide supply-demand tightness.

For context, AXT reported Q2 revenue of $47.6 million versus consensus of $34.1 million, with adjusted EPS of $0.19 beating the $0.07 estimate by over 171%. Indium phosphide substrate revenue reached a record $30.7 million in the quarter, with adjusted gross margin surging to 45.0% from 8.2% a year earlier.
