US cloud providers' 2Q26 results are positive for the Greater China technology hardware supply chain

Overview

This report conducts a cross-check of the Greater China technology hardware supply chain using the 2Q26 results and capex guidance of US hyperscale cloud providers. It notes that cloud providers' demand commentary was generally strong, and that capex increases primarily reflect rising component costs and continued capacity expansion rather than reduced server procurement, creating positive signals for AI servers, general-purpose servers, PCBs, ABF substrates, and rack assembly supply chains.

Core views

The core view is to maintain a positive stance on the server supply chain. Morgan Stanley continues to favor Wiwynn, Wistron, Gold Circuit, Unimicron, NYPCB, and Lenovo. Wiwynn is a major general-purpose server supplier to Microsoft, Meta, and Amazon and participates in Trainium server racks and AMD Helios racks; Wistron is a key L6 partner for Nvidia and AMD, with greater exposure to AI server L10/L11; Gold Circuit benefits from general-purpose server and ASIC PCB demand from US cloud providers; Unimicron and NYPCB are key ABF substrate suppliers for computing and networking chips in Greater China; Lenovo is a major general-purpose server supplier to Microsoft and Oracle.

Analysis framework

The report uses a read-across approach, mapping the 2Q26 capex guidance and 2027-2028 demand commentary from MSFT, Meta, GOOG, and AWS, together with the server supply chain, to covered Greater China technology hardware companies. The analysis focuses on whether cloud providers can absorb component price increases through capex, whether server procurement volumes are under pressure, and the degree of benefit across different supply chain segments.

Methodology notes

• Cross-company earnings mappingRead-across

  Infer the health of the Greater China hardware supply chain from US cloud providers' capex and demand commentary.

  Rather than reviewing the results of a single company, the report maps changes in capex and supply-demand commentary from MSFT, Meta, GOOG, and AWS to supply chain segments including server assembly, PCBs, ABF substrates, power supplies, thermal solutions, and interconnects.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Wiwynn

  Key beneficiary supply chain company

  Strengths

  A major general-purpose server supplier to Microsoft, Meta, and Amazon, and a participant in Trainium server racks and AMD Helios racks.

  Weaknesses

  Sensitive to the capex cycles and order timing of hyperscale cloud customers.

  Comparison

  Compared with general server assemblers, Wiwynn has more prominent exposure to key cloud customers and AI rack projects.

  Risks

  Order visibility could decline if cloud providers delay capex or new customer ramps fall short of expectations.

• Wistron

  Beneficiary of AI server assembly

  Strengths

  A key L6 partner for Nvidia and AMD, with greater exposure to AI server L10 and L11.

  Weaknesses

  Business performance is significantly affected by the ramp-up pace of Nvidia and AMD platforms.

  Comparison

  Compared with companies participating only in general-purpose servers, Wistron has more direct exposure to the AI server chain.

  Risks

  AI server platform transitions, yields, or changes in customer production schedules could affect revenue recognition.

• Gold Circuit

  PCB supply chain beneficiary

  Strengths

  Benefits from general-purpose server and ASIC PCB demand from US cloud providers.

  Weaknesses

  PCB demand may be affected by changes in server platform specifications and pricing pressure.

  Comparison

  Among the PCB supply chain companies listed in the report, Gold Circuit participates in key platforms alongside WUS PCB, TTM, and ISU.

  Risks

  Margins could come under pressure if component price increases cannot be passed through smoothly or customers demand price reductions.

• Unimicron

  Key ABF substrate supplier

  Strengths

  A key ABF substrate supplier for computing and networking chips in Greater China, and included in the supply chain maps for Amazon Trainium, Google TPU, and Meta MTIA.

  Weaknesses

  Sensitive to high-end substrate demand, capacity utilization, and customer qualification cycles.

  Comparison

  Alongside NYPCB, it is one of the key ABF substrate beneficiaries emphasized in the report.

  Risks

  Substrate orders could be affected if demand for high-end chips or networking chips slows.

• NYPCB

  Key ABF substrate supplier

  Strengths

  Identified by the report as a key ABF substrate supplier for computing and networking chips in Greater China.

  Weaknesses

  Affected by fluctuations in high-end substrate demand and customer concentration.

  Comparison

  Together with Unimicron, it is viewed as a major beneficiary of the ABF substrate chain.

  Risks

  Platform ramp timing, pricing competition, and capacity expansion risks could affect profitability.

• Lenovo

  General-purpose server supplier

  Strengths

  A major general-purpose server supplier to Microsoft and Oracle.

  Weaknesses

  Compared with AI-specific rack suppliers, it has less exposure to the AI accelerator platforms emphasized in the report.

  Comparison

  It stands to benefit when capex supports general-purpose server demand.

  Risks

  General-purpose server procurement cycles, enterprise IT demand, and changes in cloud customer orders could create volatility.

Key data

• MSFT F1Q27/C3Q26 capex>US$50BSignificantly higher than the US$41B in F4Q26/C2Q26.

• GOOG CY26 capexUS$195-205BGuidance was raised by US$15B, with CY27 expected to increase significantly year over year.
• AWS CY26 capexUS$220BRaised by US$20B due to higher memory costs; most 2027 computing capacity has been reserved, while 2028 demand was described as “striking”.
• Industry viewIn-LineAsia Pacific industry view for Greater China technology hardware.

Impact & implications

The upward revisions to capex indicate that cloud providers are inclined to absorb higher component costs to maintain the pace of expansion, supporting server unit procurement, AI server racks, PCB, and ABF substrate suppliers. If demand continues to exceed supply, suppliers with key customers, critical processes, or high-end server exposure may gain stronger order visibility.

Risks

• US cloud providers have not generally provided clear CY27-28 capex guidance, leaving uncertainty around longer-term demand.
• If component price increases exceed cloud providers' ability to absorb them within their budgets, concerns about downward revisions to server procurement volumes could resurface.
• Supply chain companies have relatively high dependence on a small number of hyperscale cloud customers, Nvidia, AMD, or proprietary ASIC platforms.
• Platform qualification, capacity expansion, yields, production schedule changes, and pricing competition could affect the actual degree of benefit to suppliers.
• Morgan Stanley disclosed investment banking or other service relationships with several covered companies; investors should be aware of potential conflicts of interest.

What to watch

• Subsequent CY27-28 capex guidance from MSFT, GOOG, AWS, and Meta.
• Whether AI server and general-purpose server orders continue to exceed supply capacity.
• Changes in memory, PCB, and ABF substrate prices and their impact on procurement volumes.
• New cloud customer ramps at Wiwynn and progress on Trainium racks and AMD Helios racks.
• Wistron's order share in Nvidia and AMD L6, L10, and L11 server chains.
• Qualification and capacity utilization of Gold Circuit, Unimicron, and NYPCB in ASIC, CPU, GPU, and networking chip supply chains.
