Prepared Metrics

Q&A Batch (1-5 of 13)

Q1 — Ruplu Bhattacharya

• Topic: Guidance slowdown in H2 FY2026 and free cash flow risk
• Key points:
  • Revenue guidance: Q1 YoY growth 51%, full-year 37%, implying slower growth in remaining three quarters.
  • EPS guidance: Q1 YoY growth 71%, full-year 45%, indicating some operating leverage decline in later quarters.
  • CapEx increased to $1 billion; free cash flow maintained at $500 million.
  • Bookings in 2025 were record; build-out is based on booked business with low program materialization risk.
• Mgmt stance: Bullish — confident in FY2026 outlook; customer forecasts exceed $17B guide; pragmatic view beyond two quarters; strong cash generation track record (positive FCF every quarter for ~7 years).

Q2 — Samik Chatterjee

• Topic: CapEx investment timeline and CCS growth trajectory into 2027
• Key points:
  • CapEx investments are based on booked business; enable capacity for 2027 and 2028.
  • CCS growth updated: 2026 CCS growth now ~$4.5B (vs. ~$3.5B three months ago); 2027 CCS growth now ~$7B (vs. ~$5B previously).
  • Digital native customer progressing as expected; meaningful contribution in 2027, included in numbers.
• Mgmt stance: Bullish — accelerating CCS growth; demand outlook robust; capacity can support beyond current heightened confidence outlook.

Q3 — Thanos Moschopoulos

• Topic: Margin trajectory amid enterprise mix shift
• Key points:
  • Enterprise business growing strongly; next-generation program already won, ramping into 2027.
  • Networking (400G, 800G, 1.6T) also strong in 2026 and 2027, helping operating leverage and mix.
  • FY2026 margin outlook: 30 bps expansion, considered a floor; management expects to do better.
• Mgmt stance: Bullish — strong operating leverage from enterprise; no large fixed headwind; networking programs running concurrently support margins.

Q4 — Michael Ng

• Topic: Capital intensity and CapEx sustainability
• Key points:
  • Majority of CapEx is growth CapEx; maintenance CapEx ~$70M–$80M, predictable as % of revenue.
  • $1B CapEx tied to specific won programs generating material revenue in 2027 and 2028.
  • CapEx expected to moderate when growth investments return to maintenance levels.
• Mgmt stance: Neutral — no explicit revenue-to-CapEx ratio; CapEx will increase if wins continue; eventual moderation expected.

Q5 — Karl Ackerman

• Topic: Opportunities in scale-up XPU networks and co-packaged optics
• Key points:
  • Increasing R&D in AI/ML networking for scale-up and scale-out fabrics; digital native and other early engagements are growth drivers.
  • 1.6T wins already used for both scale-up and scale-in; funnel of opportunities diversifying.
  • Co-packaged optics conversations increasing; mass adoption expected more toward 3.2T, not yet for CPO.
• Mgmt stance: Bullish — major growth opportunity in scale-up; well underway capturing it; CPO still early-stage.

Q&A Batch (6-10 of 13)

Q6 — Tim Long

• Topic: New program wins and long-term outlook
• Key points:
  • Visibility is "unprecedented," extending fully into 2027 and with many customers into 2028.
  • Future products include fully integrated rack systems (scale-up and scale-out) and leading-edge switching (3.2T samples due late 2026, with co-packaged optics proof-of-concepts already underway).
  • Customers now view CLS as a technology leader, not just a supply chain partner.
• Mgmt stance: Bullish — strong backlog and technology roadmap alignment driving investment decisions.

Q7 — David Vogt

• Topic: Digital native customer scope and CapEx allocation
• Key points:
  • For the digital native customer, 2026 will be largely samples, with a ramp starting in early 2027; the program is on track.
  • CapEx of $1 billion is allocated geographically (Thailand, Richardson TX, Fort Worth) to support multiple customers.
  • The "vast majority" of CapEx is tied to programs with existing hyperscalers; some investment is for the digital native ramp in 2027.
• Mgmt stance: Neutral — solid relationship with digital native, but most spending is on high-confidence hyperscaler programs.

Q8 — Paul Treiber

• Topic: Returns on new programs and competitive intensity
• Key points:
  • CLS is ROIC-driven, focusing on strong profitability and disciplined investment; business cases must hold.
  • Programs are becoming more complex; some business CLS chose not to compete on price in 2025 returned in 2026 because competitors could not execute.
  • Competitive moat: engineering for complex products plus ability to produce at scale, providing tailwinds in 2026 and into 2027.
• Mgmt stance: Bullish — disciplined approach and execution capability are driving returns and market position.

Q9 — Ruben Roy

• Topic: Shift to HPS design-led solutions and margin impact
• Key points:
  • At 1.6T and moving to 3.2T, engineering complexity is driving more HPS engagement on the networking side.
  • On AIML compute, CLS focuses on HPS and JDM design-oriented engagements, with several projects in the pipeline to improve HPS involvement.
• Mgmt stance: Bullish — increasing complexity creates more opportunities for design-led, higher-margin engagements.

Q10 — Steven Fox

• Topic: CLS position with largest customer (Google) on AIML compute
• Key points:
  • Partnership with Google is "never been stronger or more integrated"; no indication of new entrants into that market.
  • CLS is a preferred partner on leading-edge compute programs (TPUs), with joint commitment for current and future generations.
  • Capacity expansions support Google as well as growth from other hyperscale and digital native customers.
• Mgmt stance: Bullish — strong, long-standing relationship and no competitive disruption.

Q&A Batch (11-13 of 13)

Q11 — John Chao

• Topic: 成本通胀与利润率影响
• Key points:
  • 管理层已将通胀和定价因素纳入已公布的指引数字中。
  • 网络业务采用交钥匙模式（包含硅片），价格通胀可转嫁给客户；计算业务则通常不包含硅片。
  • 目前未看到利润率压缩，但如果硅片未来成为填充材料中更大的组成部分，则可能产生影响，但目前不在视野内。
  • 收入同比增长有小部分来自平均售价（ASP）上涨，但绝大多数增长来自出货量（units）增加。
• Mgmt stance: 谨慎乐观。目前通胀可控且成本可转嫁，未对利润率产生实际冲击，但提示了未来潜在风险。

Q12 — Todd Coupland

• Topic: 1.6T项目进展与需求前景
• Key points:
  • 目前有10个活跃的1.6T项目在管道中；其中约5个将在2026年下半年开始爬坡，并延续至2027年；其余仍在开发中，将在2027年晚些时候至2028年爬坡。
  • 关键制约因素是按时完成开发周期，目前硅片和整体进度均符合预期。
  • 800G需求在2025年大幅增长，并将持续至2026年；400G需求在2026年仍保持强劲贡献；1.6T将在年底加入。
• Mgmt stance: 乐观。强调下一代技术并未替代上一代，多代技术并行增长带来对网络业务的强烈信心。

Q13 — Atif Malik

• Topic: TPU合作关系与第三方市场机遇
• Key points:
  • 管理层澄清，公司并非TPU项目的独家供应商，历来也不是。出于业务连续性计划，大多数超大规模客户都有第二供应商，但公司是TPU项目的首选合作伙伴。
  • 份额主要根据绩效授予，公司的绩效非常强劲。
  • 如果谷歌TPU被其他客户采用，需求增长将通过谷歌的供应链流动。作为其首选制造合作伙伴，公司预期能够支持该增长。
• Mgmt stance: 自信/乐观。否认了新的披露信息，强调首选合作伙伴地位稳固，并预期能受益于TPU更广泛的市场采用。
