Why Is Amkor Technology Stock Soaring Wednesday?

Amkor Technology (AMKR) jumped nearly 6% in premarket trading Wednesday after announcing a 10-year partnership with Taiwan Semiconductor Manufacturing Co. to expand advanced semiconductor packaging and testing capacity in Arizona. The collaboration targets U.S. supply chain strengthening for AI and high-performance computing chips.

The move comes as AMKR trades near its 52-week high following a 325.94% gain over the past year. Despite the rally, analysts hold a consensus Hold rating on the stock with an average price target of $69.

The Arizona expansion represents a significant commitment to domestic semiconductor infrastructure, pairing Amkor's packaging and testing expertise with TSMC's manufacturing capabilities. The partnership addresses growing demand for advanced chip packaging required by AI workloads and HPC applications.
