ASE Technology May revenue climbs 29% on surging backend chip demand

ASE Technology Holding (NYSE:ASX) reported a sharp acceleration in its monthly sales, driven by strong global momentum for its outsourced semiconductor backend services.

The Kaohsiung, Taiwan-based provider of chip packaging and testing infrastructure recorded unaudited consolidated net revenues of NT$63,033 million ($2,001 million) for May 2026.

The monthly performance represents a 1.3% sequential growth compared to April and a 28.6% increase year-over-year when measured in New Taiwan dollar terms.

Growth was predominantly anchored by the company's core Assembly, Testing, and Material (ATM) segment, which has continued to see high capacity utilization as global chip designers scale up production volumes.

Net revenues from ATM operations reached NT$42,162 million ($1,338 million) during May.

The standalone segment’s output marks a 4.1% sequential uptick from the prior month and a substantial 37.9% jump over the same period in 2025.
