Extended-hours trading shows ASX at $42.77, down 2.62% from the regular-session close of $43.92. The regular session gained 4.42% ahead of the release, suggesting the strong results were partially priced in, with the after-hours dip potentially reflecting the elevated capex spend and rising leverage.
ASEH delivered its strongest YoY profit growth in recent memory, but the after-hours selloff suggests the market is weighing the capex intensity and rising leverage against the AI-driven revenue surge.
ASEH's 44.8% YoY revenue growth and ATM gross margin expansion to 30.6% reflect the ongoing AI-driven semiconductor assembly and test boom. The US$2.1B quarterly capex underscores the capital intensity required to capture advanced packaging demand, consistent with broader OSAT industry trends.
