Prepared Metrics

Q&A Batch (1-5 of 8)

Q1 — Charles Shi

• Topic: 欢迎新任CFO Kevin Engel
• Key points: 无具体财务数据或指引内容。
• Mgmt stance: 中性（仅为礼节性问候，未涉及业务判断）。

Q2 — Kevin Engel & Megan Faust

• Topic: 2026年资本支出结构、美国工厂投资节奏及政府补贴处理
• Key points:
  • 2026年CapEx中65%-70%用于设施，30%-35%用于设备；设备支出同比增约40%，主要用于韩国HDFO/测试及台湾300mm产能扩张。
  • 美国亚利桑那项目总投资70亿美元，分两阶段：第一阶段约35亿美元，其中60%为建筑支出；建筑预计2027年中完工，因此2026年至2027年上半年为资本支出高峰期。
  • 政府激励（35%投资税收抵免+直接拨款）将滞后于投资发生，2026年指引中“净CapEx”几乎未包含这些抵免；未来将净额列示。
• Mgmt stance: 中性偏积极（强调设备支出大增反映先进封装强劲需求；客户承诺（预付款/装载协议）已部分执行，另有在谈，将贡献资金；债务容量充足（债务/EBITDA仅1.2倍），可灵活融资）。

Q3 — Craig Ellis

• Topic: 计算业务增长驱动、数据中心HDFO项目进展及融资补充
• Key points:
  • 2026年计算业务同比增20%，其中PC市场偏软，数据中心为增长主力；2.5D和HDFO平台全年预计几乎翻三倍。
  • 两个数据中心HDFO项目：一个将实现非常陡峭的爬坡并达到高产量；另一个也在强劲爬坡，年底可能达到满产，但不确定，贡献将显著。
  • 亚利桑那项目总融资中，政府激励可达约28.5亿美元；客户承诺已有部分执行、其余在谈；公司债务容量充足（债务/EBITDA 1.2倍），正评估多种债务工具以优化股东回报。
• Mgmt stance: 积极（数据中心HDFO需求强劲，客户承诺和政府激励提供资金保障，财务灵活性高）。

Q4 — Kevin Engel & Megan Faust

• Topic: 各终端市场展望及利润率指引
• Key points:
  • 通信：手机销量大致持平，但向高端机型转移有利于Amkor（更高单机价值）；计算：PC销量略降，但AI应用和ARM架构迁移利好；汽车/工业：汽车销量持平，混动/电动化提升半导体含量，主流市场缓慢复苏（已连续三个季度环比改善），先进领域（车载计算、ADAS、信息娱乐）增长强劲；消费：取决于消费者情绪和新品发布；非AI/非先进汽车领域为个位数增长。
  • Q1毛利率指引中点13%，受Q4资产出售影响；剔除该一次性项目后，增量利润率符合30%模型；全年有望实现30%增量利润率（剔除资产出售影响），受益于利润改善举措。
• Mgmt stance: 积极（各市场结构性利好，先进封装驱动利润率改善，全年利润率目标可达成）。

Q5 — Ben Reitzes

• Topic: 通信业务季度/年度展望及亚利桑那项目与台积电合作进展
• Key points:
  • Q1通信：iOS方面，手机发布周期强劲，展望积极；Android方面，相对稳健，略有下降但无担忧，可能与向高端机型转移有关（Amkor参与度更高）。
  • 亚利桑那项目：与台积电的技术和制造需求讨论持续进行，合作延伸至终端客户；自2025年10月破土动工以来，客户兴趣持续上升，涵盖通信、汽车、消费等所有市场。
• Mgmt stance: 积极（通信业务受高端机型支撑；美国制造项目客户兴趣广泛且增强，与台积电合作进展良好）。

Q&A Batch (6-8 of 8)

Q6 — Megan Faust

• Topic: CapEx funding, balance sheet, and revenue ramp profile
• Key points:
  • No update on timing or magnitude of funding; evaluating customer discussions and balance sheet options in parallel.
  • Can operate comfortably with $500 million cash on balance sheet.
  • Expects decrease in interest expense even if debt increases, due to capitalizing interest on construction.
  • Revenue ramp is back-end second half loaded: PC-related products ramping early (one already in production), CPU data center devices step up in H2.
• Mgmt stance: Neutral on funding (no decisions yet); bullish on ramp profile (expects accretive outcome from H2 efficiencies).

Q7 — Steve Barger

• Topic: Gross margin recovery and AI-related packaging revenue
• Key points:
  • Vietnam reached breakeven in Q4 2025 and expects to continue in Q1 2026 (typically lowest quarter).
  • Gross margin impact from Vietnam not meaningful going forward; product mix (SiP) is the main driver.
  • AI-related advanced packaging revenue exited 2025 at about 20% of total revenue; expects accelerated growth in AI data center and PC areas.
• Mgmt stance: Bullish on Vietnam ramp (foundation for improvement); cautious on providing more AI revenue detail (limited additional color).

Q8 — Peter Peng

• Topic: Capacity constraints and new program qualifications
• Key points:
  • Constraints: NPI prioritization (focusing on larger opportunities in Korea); space freed up by migrating SiP to Vietnam and converting existing building to clean room in 2025.
  • New building (groundbreaking in 2025) will come online as exiting 2026, increasing Korea space ~20% since start of 2025.
  • Equipment delivery front-end loaded in 2026 to support H2 launches.
  • Two additional programs in final qualification: both CPU-related, one is new to HDFO platform; both with existing customers.
• Mgmt stance: Bullish on capacity expansion (space increasing, equipment on track); positive on new program momentum (next-gen technology rollout).
