AI summary card

U.S. cloud providers' capex remains strong, Greater China server supply chain continues to benefit

Capex guidance and demand commentary from Microsoft, Meta, Google, and AWS are broadly positive, showing that customers are absorbing component price increases while maintaining server procurement volumes, benefiting server assembly, printed circuit board, and package substrate suppliers.

The Greater China technology hardware industry view remains In-Line; the report maintains a positive view on key suppliers in server assembly, printed circuit boards, and ABF package substrates.

  • Microsoft's next-quarter capex guidance exceeds US$50B, a clear increase from US$41B in the prior quarter.
  • Google raised its 2026 capex guidance by US$15B to US$195-205B and expects significant year-on-year growth in 2027.
  • AWS increased 2026 capex by US$20B to US$220B, with most 2027 compute capacity already booked.
  • The report highlights Wiwynn, Wistron, Gold Circuit, Unimicron, NYPCB, and Lenovo as key preferred names.
  • Part of the capex increase stems from rising component and memory costs, but customers have not reduced server procurement volumes as a result.

Report interpretation

Overview

The report assesses the impact on the Greater China technology hardware supply chain by interpreting 2Q 2026 results, capex guidance, and supply-demand commentary from major U.S. hyperscale cloud providers. Statements from Microsoft, Meta, Google, and AWS are broadly consistent: AI and general compute demand remains strong, supply remains tight, and capex is staying elevated or being further raised. Morgan Stanley believes this helps alleviate market concerns that component price increases could depress server procurement volumes.

Core views

The core view is that cloud providers are choosing to increase spending to absorb component costs rather than reduce server procurement quantities, so server and rack assembly, printed circuit boards, ABF package substrates, power supplies, thermal solutions, and interconnect segments may all benefit. The report continues to prefer Wiwynn, Wistron, Gold Circuit, Unimicron, NYPCB, and Lenovo. Wiwynn benefits from multiple cloud providers as well as Trainium and AMD Helios rack projects; Wistron benefits from AI server partnerships with Nvidia and AMD; Gold Circuit benefits from general server and custom chip printed circuit board demand; and Unimicron and NYPCB benefit from ABF package substrate demand for compute and networking chips.

Analysis framework

The report uses a combination of earnings read-through and supply chain mapping: first comparing capex changes and forward demand commentary from Microsoft, Meta, Google, and AWS; then assessing the impact of cost increases on procurement quantities; and finally mapping potential beneficiaries of Amazon Trainium, Google TPU, Meta MTIA, Nvidia accelerated platforms, and AMD Helios across package substrates, printed circuit boards, chassis, server and rack assembly, power supplies, thermal solutions, slide rails, and interconnect solutions.

    Strengths
    An important general server supplier to Microsoft, Meta, and Amazon, and participates in Trainium server racks and AMD Helios racks for Meta.
    Weaknesses
    Customer concentration is relatively high, and there is still uncertainty around new cloud provider assembly partnerships.
    Comparison
    Compared with general assembly firms, it has broader coverage across multiple cloud providers and custom acceleration platforms.
    Risks
    Changes in customer project share, platform mass production progress, and supply chain execution falling short of expectations.
  • Wistron
    Beneficiary in AI server manufacturing
    Strengths
    An important L6 partner for Nvidia and AMD, with greater exposure to AI server L10 and L11 stages.
    Weaknesses
    The report does not provide detailed data on order share, profitability, or valuation.
    Comparison
    Compared with vendors providing only basic assembly, its exposure to higher-level AI server integration is more prominent.
    Risks
    AI platform transitions, customer order volatility, and mass production ramp-up risks.
  • Gold Circuit
    Beneficiary in server printed circuit boards
    Strengths
    Benefits from U.S. cloud providers' demand for printed circuit boards in general servers and custom chips.
    Weaknesses

Key data

  • Microsoft 2026 capexUS$190BApproximately US$175B after accounting for changes in lease treatment.
  • Microsoft next-quarter capex guidanceOver US$50BThe prior quarter was US$41B, representing a clear quarter-on-quarter increase.
  • Meta 2026 capex guidanceUS$130-145BThe original range was US$125-145B; the lower end was raised, but 2027 guidance has not yet been provided.
  • Google 2026 capex guidanceUS$195-205BRaised by US$15B, and the company again stated that 2027 capex will increase significantly year on year.
  • AWS 2026 capexUS$220BIncreased by US$20B due to rising memory costs.
  • AWS forward demandMost 2027 compute capacity has already been bookedThe company described 2028 demand as very strong.

Impact & implications

The capex increases and forward capacity bookings indicate strong continuity in AI and general server demand. If cloud providers continue to absorb component costs by raising budgets, the pressure on server procurement volumes may be limited, and server assembly, printed circuit board, ABF package substrate, and supporting component suppliers in Greater China are expected to benefit from orders and product mix improvement. However, the overall industry view remains In-Line, meaning supply chain positives do not necessarily imply comprehensive outperformance of the entire industry versus the broader market.

Risks

  • Part of the capex increase comes from rising memory and other component prices, so nominal spending growth may not fully translate into growth in server procurement volumes.
  • Except for Google, most cloud providers have not yet provided clear 2027 to 2028 capex guidance, and visibility into forward demand remains insufficient.
  • Demand continuing to exceed supply may lead to delivery delays, cost increases, and supply chain execution risks.
  • There is uncertainty around supplier share, customer certification, platform mass production progress, and new customer partnerships.
  • Morgan Stanley has shareholding, underwriting, investment banking, or other service relationships with many covered companies, which may create potential conflicts of interest.

What to watch

  • Whether Microsoft's next-quarter capex of over US$50B can smoothly translate into server and rack orders.
  • When Meta will announce 2027 capex guidance and the pace of its AI infrastructure investment.
  • The magnitude of Google's significant 2027 capex growth and its TPU deployment plans.
  • AWS's booked 2027 compute capacity and the realization of its stated strong 2028 demand.
  • Mass production progress and supplier share changes for Trainium, TPU, MTIA, Nvidia accelerated platforms, and AMD Helios.
  • Whether rising memory and key component prices begin to compress procurement volumes or supply chain margins.
