Global outsourced semiconductor assembly and test (OSAT) leader ASE Technology Holding (ASEH) held an earnings call on April 29, reporting a robust first quarter of 2026 that broke from the traditional seasonal slowdown. Growth was driven primarily by sustained strong demand for leading-edge advanced packaging (LEAP) technologies, alongside a simultaneous rebound in wire bonding orders — together fueling an 87% year-on-year surge in quarterly net profit after tax, the second highest on record for the period.
