Prepared Metrics

Q&A Batch (1-5 of 7)

Q1 — Jonathan Dorsheimer

• Topic: 功率业务细分动态及关税影响
• Key points:
  • 功率整体：2025年下半年略好于上半年；中国客户对SiC增加产能，非中国客户做节点转换；硅功率（非SiC）为最大TAM，包含薄片、质子注入等差异化应用。
  • 关于关税：2025年通过全球制造布局管理，但并非免疫；2026年关税成本可能从库存进入P&L，团队正在寻求缓解，具体量化待后续模型提供。
• Mgmt stance: 中性偏谨慎，因关税环境动态且2026年影响可能加大。

Q2 — Craig Ellis

• Topic: 中国市场需求展望及存储器复苏信号
• Key points:
  • 中国：2026年需求取决于终端环境及芯片自给自足进展，目前仍低于目标；中国客户积极对接技术路线图。
  • 存储器：需求来自DRAM和HBM，部分供应商2026年已售罄，高利用率及升级活跃；NAND仍低迷；韩国制造商份额50%为历史情况，期望在复苏时延续。
• Mgmt stance: 对中国中性偏积极（客户行为正常）；对存储器市场偏乐观（明确为 bright spot）。

Q3 — Christian Schwab

• Topic: 存储器产能周期收入弹性及成熟市场复苏判断
• Key points:
  • 每新增10万片晶圆产能（100k wafer starts），需45–55台离子注入机（NAND和DRAM强度相同）。
  • 通用成熟市场（General Mature）取决于宏观（消费、汽车、工业），目前仍“bouncing along the bottom”，部分客户高利用率，部分仍有过剩产能。
• Mgmt stance: 对存储器中性偏积极（提供具体资本强度数据）；对成熟市场谨慎，认为尚未确认整体回暖。

Q4 — Jack Egan

• Topic: CS&I收入可持续性及第四季度订单增长假设
• Key points:
  • CS&I收入创新高（$71M），部分来自客户补库存和消耗品略增（导致当季毛利率下降），升级业务在存储器市场持续强劲。
  • 第四季度订单预计环比增长，跨所有客户；存储器通常按预测生产，订单与出货可能同季实现。
• Mgmt stance: 谨慎乐观，强调存储器为亮点，但整体复苏尚未全面确认。

Q5 — Mark Miller

• Topic: 碳化硅（SiC）在电动汽车中的渗透趋势及2026年展望
• Key points:
  • SiC：2025年下半年略好于上半年，价格下降推动更多渗透（如AC压缩机、数据中心）；汽车设计周期多年，当前SiC在纯电中渗透率约低双位数（low teens），仍有空间。
  • 中国EV市场全球最大（约3000万辆/年），竞争激烈且政府支持有效，国内厂商正向海外市场拓展；美国及全球EV增长难以精确预测。
• Mgmt stance: 长期看多SiC（“还有很长的路”），但短期需求具体数字不确定。
