    Charlie Chan's questions to ASE Technology Holding Co Ltd (ASX) leadership

    Charlie Chan's questions to ASE Technology Holding Co Ltd (ASX) leadership • Q2 2025

    Question

    Charlie Chan asked for a reconciliation between ASE's strong second-half guidance and the perceived market weakness in PCs, smartphones, and automotive. He also questioned why ASE maintained its advanced packaging revenue growth target of $1 billion, while foundry partners like TSMC revised their forecasts upward due to AI strength.

    Answer

    COO Tien Wu explained that the strong outlook is based on firm customer orders covering AI, wireless, industrial, and automotive sectors. He clarified that the company is capacity-constrained in advanced packaging, and expansion is limited by execution factors like facility readiness, human talent, and machine delivery lead times, not a lack of demand or unwillingness to invest. CFO Joseph Tung added that a healthy recovery is also visible in the general market, with double-digit quarter-over-quarter growth in all segments.

    Charlie Chan's questions to United Microelectronics Corp (UMC) leadership • Q1 2025

    Question

    Charlie Chan of Morgan Stanley asked for more color on the drivers behind the Q2 gross margin guidance of 30%. He also questioned if customers are requesting an acceleration of the U.S. partnership with Intel and whether UMC would consider migrating to more advanced nodes. Finally, he asked about the implied second-half seasonality based on the full-year outlook.

    Answer

    CFO Chi-Tung Liu attributed the margin performance to proactive cost reduction efforts offsetting headwinds, but cautioned that the better-than-expected first half only provides a buffer for second-half uncertainty. He confirmed customers wish to accelerate the 12nm U.S. project, but the current timeline is already aggressive and on track. While open to future opportunities, the current contract is limited to 12nm. For the full year, Liu reiterated the goal to outperform the addressable market's low-single-digit growth.

    Charlie Chan's questions to United Microelectronics Corp (UMC) leadership • Q2 2024

    Question

    Charlie Chan of Morgan Stanley sought clarification on the FX impact on Q2 gross margin, questioned how UMC achieved strong revenue guidance with firm pricing amid a slow market recovery, and asked about the risk to its interposer business from next-gen GPUs. He also inquired about the progress of the Intel partnership and the reason for UMC's strong outlook when a key customer's inventory was rising.

    Answer

    CFO Chi-Tung Liu quantified that a 3% TWD depreciation contributed about 1.2-1.3 percentage points to Q2 gross margin. President Jason Wang explained that revenue strength comes from disciplined portfolio management and seeing some segments exit inventory correction. He addressed interposer risk by highlighting a continuous product pipeline and development of wafer-to-wafer hybrid bonding. Wang confirmed the Intel partnership is on track for 2027 and unaffected by leadership changes, and that overall inventory levels (excluding auto) are improving and returning to seasonal patterns.
