AMKR

In the past six months, Amkor Technology, Inc. (AMKR) stock increased by 15.61%, and over the past year, it rose by 80.26%. Key events impacting the stock include the announcement in September 2026 of Phase 2 of its Arizona advanced packaging and test campus expansion, increasing the total planned investment to approximately $12 billion due to customer demand, which positively impacted the stock. Earnings reports also played a role: in July 2026, Amkor reported Q2 2026 earnings that beat consensus estimates for both EPS and revenue, though the stock tumbled later that month following weak Q3 revenue guidance. Q1 2026 also saw record net sales and EPS, exceeding analyst expectations. Furthermore, an executive vice president notified their intention to sell 1,000 shares in September 2026.
