The explosive demand for artificial intelligence computing power is creating an unprecedented boom cycle for printed circuit boards (PCB), a core hardware foundation. Wus Printed Circuit(Kunshan)Co.,Ltd. (SHE: 002463), a leading PCB firm with an A-share market value exceeding 260 billion yuan, has once again submitted a listing application to the Hong Kong Stock Exchange after a six-month interval.
Strategic Rationale for the Hong Kong Listing Journey
The company's pursuit of a Hong Kong IPO began last year, with this application representing a swift second attempt following the lapse of its initial filing after six months. Notably, the bullish narrative around PCBs has fueled a valuation surge. The company's A-share price has surged 88.78% year-to-date. In comparison, its domestic rival Shennan Circuits (002916.SZ) rose 60.79%, while Dongshan Precision (002384.SZ) jumped 151.62%, highlighting an opportune time for a Hong Kong listing. Another competitor, Victory Giant Technology (300476.SZ), successfully achieved an A+H listing this year, becoming the largest IPO by fundraising size. Despite recent price fluctuations, its Hong Kong share price of HK$338.40 remains about 61% above its April offering price of HK$209.88, underscoring strong market appetite. Dongshan Precision has also filed for a Hong Kong listing, aiming to capitalize on this favorable market trend for an A+H structure.
The company's listing documents indicate that proceeds from the Hong Kong IPO will fund capacity expansion, R&D for high-performance PCBs in data communications and smart automotive sectors, forward-looking technological innovation, strategic investments and acquisitions, and working capital supplementation. The company operates five major production bases, four in China (Kunshan, Huangshi, Jintan) and one in Thailand. According to its application, as of March 31, 2026, capacity utilization rates at its two Kunshan plants exceeded 99%, with rates in Huangshi, Thailand, and Jintan reaching 99.7%, 99.1%, and 92.5% respectively, indicating near-full operation.
In March, the company announced plans to invest 5.5 billion yuan to build new PCB production projects and supporting facilities for high-layer-count, high-frequency, high-speed, high-density interconnect, and high-current PCBs. On April 1, it announced another planned investment of 6.8 billion yuan for PCB production projects. These combined 12.3 billion yuan in planned investments within a month represent about 38% of its total assets of 32.72 billion yuan as of March 31, 2026. This substantial capital need underscores the rationale for raising funds via a Hong Kong listing to support expansion, likely for projects in Kunshan, Huangshi, and Jintan.
Furthermore, a significant portion of its revenue comes from overseas markets. Financial data shows revenue from outside mainland China, including bonded zones, accounted for 82.1% and 84.3% of its total for the 2025 fiscal year and Q1 2026, respectively. Its core clients include international leaders like NVIDIA and Canadian EMS giant Celestica. An A+H structure is often viewed more favorably by such global clients. A Hong Kong listing would facilitate access to global sovereign wealth funds and long-term overseas capital, enhance its international brand, enable direct foreign currency investments, mitigate forex volatility, and support its global strategy.
Growth Drivers: Acceleration from AI Computing Demand
While PCBs for standard servers are low-margin, high-end backplanes for AI training servers and next-generation AI cabinets represent a highly lucrative segment. The company is a dominant leader in the AI computing PCB space. According to research it commissioned, the company ranked first globally by data center PCB sales revenue in 2025, with a 10.2% market share. It also ranked first globally for sales revenue of 22-layer and above multi-layer PCBs in 2025, with a 14.9% share.
Sales revenue for its 22-layer and above PCB products grew strongly in 2025 and Q1 2026, increasing their contribution to total revenue from 38.4% in 2023 to 54.9% in 2025 and 59.4% in Q1 2026. This product mix upgrade has steadily driven gross margin higher, from 28.4% in 2023 to 33.8% in 2025, with Q1 2026 gross margin expanding to 34.8% from 31.3% a year earlier. Consequently, despite ongoing R&D investment, its net profit margin attributable to shareholders expanded from 16.9% in 2023 to 20.2% in 2025, and improved by 1.1 percentage points year-on-year to 20% in Q1 2026.
The core barrier in the PCB industry is not machinery, but customer certification. Top-tier computing and automotive client certifications can take 1-3 years, leading to long-term, sticky relationships with high switching costs. The company boasts a portfolio of global top-tier clients, covering four of the world's top five communications equipment makers, four of the top five listed AI computing infrastructure firms, and four of the top five automotive Tier-1 suppliers. Although revenue concentration from its top five clients rose to 58.4% in Q1 2026, these are all industry leaders with stable capital expenditure and high-quality orders.
Potential Challenges: The Flip Side of the High-Growth Story
The company is in a strategic phase of expansion for growth, but the significant capital expenditure brings notable cash flow pressure. As noted, the 12.3 billion yuan in planned investments announced within a month exceeds one-third of its total assets. Its debt-to-asset ratio has increased from 38.7% at the end of 2023 to 46.5% at the end of 2025, and further to 48.6% as of March 31, 2026.
The exceptionally high demand in the AI computing PCB segment has attracted numerous global PCB manufacturers. The capital market enthusiasm for AI also allows peers like Dongshan Precision and Victory Giant Technology to fund their expansions through elevated valuations and expanded financing channels, all racing to boost high-end PCB capacity. Capital influx could likely lead to industry overcapacity within 1-2 years, potentially triggering price wars that compress product gross margins and significantly increase profitability challenges.
The company's current high valuation is heavily reliant on the AI computing boom. If commercialization of large language models falls short of expectations or cloud providers cut spending, the industry's high-growth phase could end abruptly, leading to a significant valuation correction. Concurrently, ongoing technological evolution, such as substrate-like PCBs and micro-assembly, may gradually replace traditional high-end PCBs. If the company's progress in forward-looking technologies like CoWoP lags behind peers, its long-term growth potential could be constrained. Additionally, geopolitical and trade uncertainties, particularly between the US and China, pose a persistent risk of order diversion.
Concluding Assessment
Leveraging its leading position in high-end computing PCBs, global top-client barriers, and improving profitability, the company currently possesses strong growth momentum. Fundraising from a Hong Kong listing should help alleviate capital expenditure pressure from expansion and R&D, establish dual domestic and international financing platforms, and further solidify its global leadership in high-layer-count boards for data centers. However, risks are evident beneath the prosperous surface: collective industry capacity expansion could easily trigger supply-demand imbalance and price competition; the rising debt ratio reduces its financial buffer; its valuation is closely tied to AI capital expenditure cycles, making it vulnerable to correction if commercialization disappoints; and long-term variables like substrate substitution and geopolitical trade volatility add uncertainty. High-speed growth is not without potential pitfalls.
Overall, AI computing demand has opened a long-term value re-rating opportunity for the PCB industry, with a clear trend of leading players strengthening their positions. The company holds three core advantages: technology, clients, and global production capacity. An A+H structure will provide crucial support for navigating cycles. Moving forward, its ability to efficiently absorb massive investments, defend gross margins, and outpace industry technological shifts will be the key tests determining its medium-to-long-term growth quality. Investors should rationally differentiate between the sector's long-term potential and short-term valuation froth, carefully weighing the balance between cyclical tailwinds and multiple underlying risks.
