ASE Technology Holding (NYSE:ASX) reported a significant surge in fourth-quarter profit on Thursday, bolstered by the rapid expansion of artificial intelligence (AI) applications and high-performance computing (HPC) demand.
The Kaohsiung, Taiwan-based company, the world’s largest outsourced semiconductor assembly and test (OSAT) provider, reported fourth-quarter net income of $474.1 million (NT$14.71 billion), a substantial jump from the $283 million (NT$9.31 billion) reported in the same period a year prior.
Quarterly revenue reached $5.73 billion, as the company’s Assembly, Testing, and Material (ATM) business outpaced broader market growth with a 24.2% year-over-year revenue increase.
Management highlighted that gross margins for the quarter improved to 19.5%, driven by higher utilization rates in advanced packaging lines.
The company’s focus on "LEAP" (Leading-edge Advanced Packaging) technologies—including Fan-out, 2.5D/3D IC, and System-in-Package (SiP)—has allowed it to capture a larger share of the booming AI accelerator market.
For the full year 2025, ASE reported a total profit of $1.31 billion on revenue of $20.73 billion, reflecting a resilient recovery from the previous year’s cyclical downturn.
