Taiwan Semiconductor stock surged almost 17% year-to-date, topping the PHLX Semiconductor Index’s over 14% (whose components include Nvidia NVDA and Taiwan Semiconductor. The company reported second-quarter 2025 revenue of 933.79 billion New Taiwan dollars (about $31.9 billion), up from 839.25 billion ($25.5 billion) New Taiwan dollars in the first quarter. This marks a 38.6% year-over-year increase, surpassing the company’s guidance of $28.4 billion to $29.2 billion issued in April.

Bloomberg analyst Charles Shum credited the strong results to surging AI-related demand from chipmakers like Nvidia and growing outsourcing orders from Intel INTC. He noted that this momentum is helping offset weakness in the mobile and consumer electronics sectors, keeping Taiwan Semiconductor on track to achieve its 25% annual sales-growth target in U.S. dollars.

Shum added that operating margins may land near the lower end of guidance, around 47%, due to a weaker U.S. dollar.

Meanwhile, Taiwan Semiconductor is accelerating its U.S. expansion plans, reportedly shifting focus to American operations amid potential chip import tariffs from Washington.
