Insights

Financial Analyst

ASE Technology's March and Q1 2025 revenue figures demonstrate impressive growth trajectories across multiple metrics. March revenues of US$1,638 million show a substantial 19.2% sequential increase and 13.1% year-over-year growth, signaling strong business momentum in their semiconductor packaging and testing operations.

The company's core Assembly, Testing and Material (ATM) business segment is performing exceptionally well, with March revenues increasing by 16.5% year-over-year and Q1 revenues up 11.9% compared to Q1 2024. This outperformance of the ATM segment relative to overall company results indicates strength in ASE's fundamental operations.

A critical observation is the divergence between NT$ and US$ results. While Q1 2025 shows an 8.7% sequential decline from Q4 2024 in NT$ terms, it actually represents a 10.5% increase when measured in US dollars. This discrepancy highlights significant currency effects benefiting dollar-denominated performance metrics.

The 19.2% acceleration in March revenue compared to February suggests building momentum entering Q2 2025. This follows consistent year-over-year growth patterns across both monthly and quarterly metrics, with Q1 2025 overall revenue reaching US$4,518 million—a 6.5% increase from Q1 2024.

The double-digit growth rates in core business segments and strong March performance provide clear evidence of robust business fundamentals at ASE Technology, positioning the company well in the semiconductor services market.
