What Delton Technology Actually Does {#what-delton-does}
Delton Technology manufactures printed circuit boards β the layered substrates that carry electrical signals inside servers, networking equipment, and data centre hardware. Not consumer electronics PCBs. These are high-layer-count boards (16+ layers, some exceeding 30) designed for the thermal and signal-integrity demands of AI training and inference servers.
The company ranks third globally in the high-performance server PCB segment, according to Prismark's 2025 data. TTM Technologies (US) and Unimicron (Taiwan) hold the top two positions. Delton's manufacturing base sits in mainland China, primarily in Huizhou, Guangdong province, giving it a labour and infrastructure cost advantage over competitors in higher-cost regions.
Revenue for FY2025 came in at approximately RMB 5.8 billion (~US$800 million), with a gross margin around 28%. That margin is above average for the PCB industry (typically 20-25% for standard boards) because high-performance server PCBs command premium pricing due to their technical complexity and lower defect tolerances.
IPO Details β Pricing, Size, and Use of Proceeds {#ipo-details}
Delton priced its offering at the top of the indicative range, which usually signals strong institutional demand. Here are the key numbers:
| Detail | Value |
|---|---|
| IPO Price | HK$38.80 per share |
| Total Raised | HK$3.31 billion (~US$422 million) |
| Market Cap at Listing | ~HK$33 billion |
| Listing Date | March 20, 2026 |
| Exchange | HKEX Main Board |
| Retail Oversubscription | ~15x |
| Cornerstone Investors | ~40% of offering |
| Use of Proceeds | Capacity expansion (~55%), R&D (~25%), working capital (~20%) |
The cornerstone tranche at 40% is meaningful β it locks up a significant portion of shares for six months, reducing immediate selling pressure. Cornerstone investors included a mix of sovereign wealth-linked funds and technology-focused institutional investors.
For HK retail investors considering IPO applications, understanding the subscription process and fees matters. At HK$38.80 per share with a board lot of 200 shares, one lot costs HK$7,760 plus roughly HK$50-100 in brokerage and financing fees.
The AI Revenue Concentration Story {#ai-revenue}
This is the number that drives Delton's valuation narrative: approximately 74% of revenue comes from AI computing-related PCB products. That includes boards for GPU servers (think NVIDIA HGX-style platforms), high-bandwidth networking switches, and AI inference appliances.
The remaining ~26% covers traditional enterprise server boards and telecommunications infrastructure PCBs. This segment has been essentially flat for three years while the AI portion has grown at roughly 45% annually since 2023.
What this means in practical terms: Delton's financial performance is tightly coupled to the AI infrastructure capex cycle. When hyperscalers (Microsoft, Google, Meta, ByteDance) are spending aggressively on GPU clusters, Delton's order book swells. When they pause or slow procurement β as happened briefly in mid-2024 β Delton feels it within one to two quarters.
The 74% figure also means Delton is significantly more AI-exposed than most PCB peers. For comparison, TTM Technologies derives roughly 45% of revenue from AI-adjacent products, and Unimicron sits around 50%. Delton's higher concentration is both its bull case and its vulnerability.
How Delton Compares to Recent HK Tech IPOs {#ipo-comparison}
Delton isn't the first mainland tech company to list in Hong Kong recently. Here's how it stacks up against comparable 2025-2026 HKEX tech IPOs:
| Company | IPO Date | Amount Raised | Sector | Day-1 Return | 30-Day Return |
|---|---|---|---|---|---|
| Delton Technology | Mar 2026 | HK$3.31B | AI Server PCB | +8.2% | β |
| Momenta (ζΊι§η§ζ) | Mar 2026 | HK$2.8B | Autonomous Driving | +12.5% | +6.3% |
| EverDisplay (ηΆδΏ‘θ«Ύ) | Feb 2026 | HK$4.1B | AMOLED Display | +3.1% | -2.7% |
| Chinese Chipmaker X | Jan 2026 | HK$5.2B | Semiconductor Fab | +15.3% | +11.8% |
| SenseTime (εζΉ―) | Dec 2025 | HK$6.0B | AI Software | -4.2% | -12.1% |
A few observations. Day-1 returns for hardware-focused companies (Delton, chipmakers) have been more reliable than software/AI plays in recent HK listings. The market is pricing tangible manufacturing capacity and order backlogs more generously than revenue projections based on software adoption curves.
Delton's +8.2% first-day gain was solid but not spectacular. For context on how HK IPO grey market pricing works and what that tells you about likely day-1 performance, we've covered the mechanics separately.
Genuine Risks Investors Should Weigh {#risks}
These aren't boilerplate risk factors. They're the specific issues that could materially affect Delton's stock price.
Customer concentration. Two customers β widely understood to be major US hyperscalers and their contract manufacturers β account for over 60% of Delton's revenue. The company doesn't name them in the prospectus (standard practice), but the dependency is stark. If either customer dual-sources to a competitor or brings PCB fabrication in-house, Delton loses a disproportionate share of revenue with limited ability to replace it quickly.
AI capex cyclicality. The current AI infrastructure spending wave has been running since late 2022. History suggests these cycles don't last forever. When hyperscaler CFOs eventually decide they've built enough GPU capacity for near-term needs, capex slows, and Delton's order pipeline contracts. The company's 74% AI revenue exposure means it has less diversification to fall back on during a downturn than competitors like TTM Technologies.
Margin pressure from capacity expansion. Delton is spending 55% of IPO proceeds (~HK$1.8 billion) on expanding production capacity. New fabrication lines take 18-24 months to reach full utilisation. During the ramp period, fixed costs rise before revenue catches up. If the expansion coincides with a cyclical slowdown in AI spending, the margin compression could be significant.
Geopolitical supply chain risk. Delton manufactures exclusively in mainland China. US-China technology restrictions have so far focused on chip design tools and advanced semiconductors rather than PCB fabrication, but the regulatory environment is unpredictable. Any expansion of export controls to cover high-layer-count PCBs for AI servers would directly affect Delton's ability to serve its largest customers.
Raw material costs. High-performance PCBs require specialty laminates (often from Japanese suppliers like Mitsubishi Gas Chemical and Panasonic) and copper foil. These input costs fluctuate and have limited pass-through to customers on fixed-price contracts.
What the PCB Supply Chain Looks Like in 2026 {#pcb-supply-chain}
The global PCB market is worth approximately US$95 billion in 2026, according to Prismark estimates. High-performance server PCBs β Delton's segment β represent roughly US$12 billion of that, growing at about 18% annually driven by AI server buildouts.
The supply chain runs roughly like this: laminate suppliers (Mitsubishi, Panasonic, Shengyi Technology) β PCB fabricators (Delton, TTM, Unimicron, Shennan Circuits) β server ODMs (Foxconn, Wistron, Quanta) β end customers (Microsoft, Google, Meta, Amazon).
Delton sits in a structurally decent position within this chain. PCB fabrication for AI servers requires specialized equipment (laser drilling, sequential lamination, advanced plating) that takes years to install and qualify. This creates moderate barriers to entry. A new competitor can't simply build a factory and win orders β they need to pass 12-18 months of customer qualification testing first.
That said, several Chinese competitors (Shennan Circuits, WUS Printed Circuit) are investing heavily in the same segment. The competitive moat is real but not impregnable.
Should You Subscribe to HK IPOs Like This? {#should-you-subscribe}
For retail investors in Hong Kong, IPO subscription remains a popular strategy. If you're new to this, our beginner's guide to HK IPO brokers covers the mechanics β which brokers offer the lowest fees, how margin financing works, and what to expect from allotment rates.
A few practical points specific to Delton:
Allotment probability. At ~15x retail oversubscription, most applicants for one lot would have received shares. For context on how HK IPO allotment rates work, the balloting mechanism varies by oversubscription level.
Financing cost for margin subscribers. Many HK investors use 10x or 20x margin financing for IPO applications to increase allotment chances. At current HK interest rates (~4.5% annualised), borrowing HK$155,200 for a 20x application on 10 board lots costs roughly HK$170 for a 7-day financing period. The +8.2% day-1 return on one lot (HK$637) more than covers this, but outcomes vary significantly between IPOs.
Post-IPO hold or flip? This depends on your thesis. If you believe AI infrastructure spending continues to accelerate through 2026-2027, Delton at ~18x forward P/E is not unreasonable for a high-growth PCB manufacturer. If you think the AI capex cycle is closer to its peak than its start, taking day-1 profits is defensible.
For broker options, moomoo offers HK IPO subscription with competitive financing rates β typically 1-2% lower than traditional banks for the same application period.

Final Thoughts {#final-thoughts}
Delton Technology's IPO represents a straightforward bet on the continuation of AI infrastructure buildout, filtered through the lens of a PCB manufacturer with genuine technical capabilities and a concentrated customer base.
The 74% AI revenue exposure is the defining characteristic. It's not a diversified industrial company that happens to benefit from AI tailwinds β it's a company whose financial trajectory is largely determined by whether hyperscalers keep ordering GPU servers at the current pace.
For investors comfortable with that cyclicality and the customer concentration risk, the valuation at listing (~18x forward P/E) prices in growth expectations without the extreme premiums seen in some pure-play AI software IPOs. For those who want AI hardware exposure with more diversification, ETFs tracking the broader semiconductor supply chain may be more appropriate.
