Key Q&A
Q:How will ASE's LEAP and testing segment scale by 2026, and what is the outlook for the ramp of the business?
A:ASE expects leading-edge advanced packaging to grow by more than $1 billion next year. The ramp will be led by traditional LEAP services, including substrate and testing. A more pronounced ramp-up in full-service applications is expected in the latter half of the year.
Q:What is the technology readiness for FOCoS-Bridge, and how does it impact customer engagement?
A:FOCoS-Bridge is considered important for AI system architecture, providing increased performance between processing units and memory dies. ASE has not disclosed yield details but expects different customer products to ramp in the latter half of 2026.
Q:What is the margin outlook for the LEAP and testing segment going into 2026?
A:Leading-edge advanced packaging is accretive to structural margins, which range from 24% at 70% utilization to 30% at 85% utilization. ASE expects a more favorable margin environment in 2026, with continued margin recovery and improvement.
Q:What is ASE's readiness for panel-level packaging for HPC applications, and when is the first wave of product migration expected?
A:ASE is progressing with equipment and qualification for panel-level packaging, with minor revenue expected by the end of next year. A mass migration has not yet occurred, and readiness depends on the overall ecosystem, including machinery and standards.
Q:How does ASE position itself in the migration to panel-level packaging for HPC?
A:ASE prefers to scale up when technology and standards are well-developed, ensuring optimal returns. The company is prepared to scale with foundry partners if market demand arises.
Q:What role does ASE play in HVDC (High Voltage Direct Current) power delivery for data centers?
A:ASE focuses on voltage conversion closer to the die, which is critical for power efficiency. The company sees high opportunities in this area as power efficiency becomes increasingly important for AI and data centers.
Q:What are the types of products or clients ASE is ramping for full process in late 2026?
A:ASE has not provided specific details about products or clients for 2026 but highlights opportunities due to industry-wide resource constraints and its broad exposure.
Q:What is ASE's business model for CPO (Co-Packaged Optics), and how does it position itself?
A:ASE remains agnostic to standards and methodologies, aiming to be part of the endgame solution when volumes and returns are viable. Silicon photonics is not a major revenue contributor for 2026.
Q:What is ASE's progress in ramping final test for A accelerators?
A:ASE is progressing in final test capabilities but is currently focused on wafer probe expansion for 2026. Final test exposure for AI is expected to increase in the latter half of the year.
Q:How does ASE view the wafer probe market and its competitive dynamics?
A:ASE, as the largest packager, is well-positioned for wafer probe opportunities. The company expects continued expansion and benefits from its labor-free solutions, with no significant competitive impact anticipated.
Q:What is ASE's approach to power delivery modules and voltage regulators?
A:ASE manufactures the power delivery module in-house, while the PMIC (Power Management IC) is typically customer-specified or custom silicon.
Q:Review of Unclear Management Responses
A:Management avoided providing specific details on several topics, including the exact makeup of 2026 revenue, specific customer products or clients for the full process ramp, and detailed yield information for FOCoS-Bridge. Responses often lacked clarity or were generalized, particularly regarding future product and client specifics, silicon photonics revenue, and competitive dynamics in wafer probe.
