On June 23, Amkor Technology fell 8.54% in regular trading, trading at $84.07/share, with turnover of $80.37 million.

On the news front, the semiconductor equipment sector experienced a sweeping selloff, with major peers posting near double-digit declines. Lam Research fell 10.71%, Teradyne dropped 10.34%, Applied Materials declined 10.15%, KLA-Tencor lost 9.0%, and ASML Holding fell 7.34%. The broad-based industry downturn and strong sector correlation effects served as the primary driver behind Amkor's sharp pullback.

Notably, Amkor had previously rallied on the back of a ten-year strategic partnership agreement with TSMC announced on June 16, which involves deepening collaboration on advanced semiconductor packaging capabilities in Arizona to serve global high-performance computing and AI chip mass production demand. The company had also been considering a 1 trillion Korean won expansion of its Gwangju, South Korea facility. Today's decline partially reverses those gains amid prevailing industry-wide headwinds.
