WUS Printed Circuit Suzhou survey: AI datacom PCB remains the core growth engine

Overview

This report is based on Citi's survey of WUS Printed Circuit in Suzhou on July 3, 2026, focusing on the company's AI datacom PCB product progress, 1.6T/3.2T technology roadmap, efforts to catch up in CoWoP R&D, capacity footprint, pricing strategy, and power stability advantages. The report takes an overall positive view, believing that GenAI-related PCB demand, product mix improvement, and delivery capabilities can support strong earnings growth.

Core views

The core views include: first, AI datacom products are the company's highest priority, and WUS is already a major supplier of 1.6T switches for multiple customers; second, 3.2T technology development is progressing, but the company still needs to await the 2028 standard; third, AI PCB prices are not being forced down by customers, and the competitive landscape and supplier negotiations are more important; fourth, Mainland China remains the primary area for capacity expansion, while Thailand's power stability limits large-scale capacity migration; fifth, the company reduces supply chain risks by procuring high-end raw materials in advance, promoting certification of domestic materials, and jointly developing standards with material and equipment suppliers.

Analysis framework

The report combines company research notes, management interviews, product technology roadmap analysis, capacity project tracking, pricing strategy analysis, and a valuation framework. The valuation section derives a Rmb189.0 target price using 30x 2027E P/E and explains the reasonableness of the valuation through 2026-2028E earnings CAGR, AI PCB demand, ASP/gross margin improvement, and execution capabilities.

  Core covered stock

  Strengths

  High priority on AI datacom PCBs and a major supplier of 1.6T switches for multiple customers; stable headquarters power supply and ongoing major capacity projects; high-margin AI PCBs can buffer raw material costs.

  Weaknesses

  Competitors have a first-mover advantage in CoWoP; an unstable Thai power grid limits large-scale overseas expansion; low-end automotive PCB products require customer acceptance of price increases amid rising costs.

  Comparison

  Compared with competitors already leading in CoWoP, WUS remains in an active catch-up phase; compared with Thai capacity, the company is more dependent in the short term on Mainland China capacity and power supply stability.

  Risks

  Lower-than-expected GenAI-related PCB allocation, pricing and competitive pressure in the automotive supply chain, CSP capital expenditure cuts, weak macro demand, rising material costs, and US-China geopolitical risks.

Impact & implications

If the report's assessment is realized, the investment thesis for WUS Printed Circuit will be driven primarily by AI datacom PCB demand, its share of 1.6T switch supply, future 3.2T standards, cost reductions from domestic materials, and Mainland China capacity expansion. The company's high margins on high-end AI PCBs and stable power resources should help offset raw material volatility, but pricing pressure in automotive PCBs, changes in CSP capital expenditure, and geopolitical risks could still constrain valuation.

Risks

• Lower-than-expected allocation of GenAI-related PCB share.
• Pricing pressure and intensifying competition in the automotive supply chain.
• CSP capital expenditure cuts or weaker demand caused by economic weakness.
• Tight supply of high-end raw materials or rising material costs.
• US-China geopolitical risks.
• An unstable Thai power grid could affect the pace of local capacity expansion.
• Competitors have a first-mover advantage in CoWoP, creating uncertainty around WUS's R&D catch-up.

What to watch

• Progress toward implementing the 3.2T standard in 2028 and WUS's technology readiness.
• Customer share and order sustainability for 1.6T switches.
• Ramp-up progress for the 3.3bn infrastructure project, Phase I of the 5.5bn project, Phase III of the Huangshi plant, and Phase II of Thailand Datacom.
• AI PCB pricing competition, customer price reduction pressure, and domestic material certification progress.
• CSP capital expenditure and the strength of GenAI-related PCB demand.
• Whether the company can sustain ASP and gross margin improvement in high-end AI PCBs.
