ASE Advanced Packaging Quotes Surge 20%+ Amid AI-Driven Demand Crunch

ASE Technology, a primary provider of advanced packaging services including CoWoS-adjacent SiP and substrate solutions, has reportedly raised quotes for advanced packaging by more than 20%, directly driven by surging AI hardware demand. This pricing action crosses the Critical threshold and represents a material BOM cost increase for AI accelerator integrators reliant on advanced packaging capacity.

Analysis

A 20%+ price hike from ASE — the world's largest OSAT — signals that advanced packaging capacity is now a hard constraint in the AI hardware supply chain, not merely a bottleneck. Integrators sourcing CoWoS or related advanced packaging for Nvidia H200/B100 builds should expect margin compression or pass-through pricing pressure in H2 2026, with limited short-term relief given ASE's dominant market position and the absence of near-term capacity additions at scale.
