AXT Inc's stock fell 5.10% during the overnight session on Friday, extending a recent pullback from elevated levels.

The decline is attributed to significant profit-taking pressure, as investors locked in gains after the stock surged to a 52-week high earlier in the week. The move was amplified by broad weakness in the semiconductor equipment sector, with several major peers also trading lower during the session.

This profit-taking follows the company's recent report of better-than-expected first-quarter results, which included a swing to gross profit and a 39.1% revenue increase. However, ongoing uncertainty regarding the timing of additional export permit approvals for key materials like indium phosphide may have contributed to investor caution at current price levels.
