ASE Industrial Holding Co LtdStrong AI-related advanced packaging demand driving margin expansion and raised LEAP revenue outlook.

ASE Technology's first-quarter 2026 gross margin expanded to 20.1% from 16.8% a year ago, while operating margin improved to 10.1% from 6.5%, driven by a richer mix of Assembly, Testing and Materials revenue and growing demand for advanced packaging services. The company raised its 2026 LEAP revenue outlook by about 10% to more than $3.5 billion and expects second-quarter consolidated gross margin to improve another 20 to 100 basis points sequentially. Management reiterated that ATM margins should continue rising through 2026 and reach the upper end of the company's structural margin range by year-end as AI-related packaging demand remains strong. However, accelerated investments in new LEAP production lines could temporarily weigh on quarterly profitability before new capacity begins contributing in the fourth quarter. ASE Technology's stock has surged 151.9% year to date, and the Zacks Consensus Estimate for its 2026 earnings per share has increased to 82 cents from 77 cents over the past 60 days.
