On September 14, AXT Inc fell 8.06% in pre-market trading, trading at $59.52/share, with turnover of $11.6575 million.

On the news front, three major AI giants called for slowing AI model development, triggering a broad sell-off across optical communication concept stocks. AXT Inc, as a key supplier of indium phosphide and gallium arsenide substrates used in data center connectivity and fiber optic applications, was directly impacted. Peers MaxLinear fell over 7%, while Corning, Coherent, and Applied Optoelectronics each dropped over 6%, with Lumentum and Marvell Technology declining over 5%.

Simultaneously, the semiconductor equipment sector faced systemic pressure as escalating US-China trade friction and tightened semiconductor export controls weighed heavily on valuations. Within the Semiconductor Equipment sector, Lam Research fell 8.54%, KLA Corporation fell 7.82%, Applied Materials fell 7.51%, Teradyne fell 7.34%, and ASML Holding fell 5.99%, reflecting significant industry-wide linkage effects that amplified the decline in AXT Inc shares.
