ASE Technology's stock surged 6.98% during intraday trading on Friday. The significant rally was driven by a combination of the company's robust first-quarter financial performance and its aggressive strategic expansion initiatives.

The company reported strong preliminary results for March, with consolidated net revenue reaching NT$61.58 billion, marking a 14.6% increase year-over-year and an 18.2% rise sequentially. Its core Assembly, Testing, and Material (ATM) business posted first-quarter revenue of NT$112.43 billion, surging 29.7% from the previous year, reflecting persistently strong demand in the downstream packaging and testing sector.

Furthermore, market sentiment was bolstered by ASE's capacity expansion plans. The company announced the planned acquisition of Innolux's Tainan Science Park Fab5 facility for NT$14.85 billion to address advanced packaging capacity gaps. Concurrently, it has broken ground on a new multi-billion-dollar facility at the Kaohsiung Renwu Industrial Park, targeting growth areas like AI, high-performance computing, and automotive electronics testing services. The company is scheduled to release its full quarterly earnings on April 29, with analysts maintaining an optimistic outlook.
