Denglin Falls 7% in Hong Kong Debut as Chip Packager Xinde Jumps 22%

Two mainland Chinese chip companies raised a combined HK$2.36 billion (about US$301 million) on their Hong Kong trading debuts on Tuesday, and the market immediately split them apart. GPU designer Suzhou Denglin Technology fell as much as 6.9% by the midday break, while chip packager Jiangsu Xinde Semiconductor Technology jumped 22.5% over its offer price.

The numbers were blunt. Denglin, which designs graphics processing units for AI computing, opened at HK$229, 0.9% below its HK$231 offer price, and traded at HK$215 at midday, down 6.9%. Xinde, which packages and tests chips, opened at HK$10.70, 20.5% above its HK$8.88 offer price, and stood at HK$10.88 by midday, up 22.5%, Reuters reported. The broader market was calm: the Hang Seng Index rose 0.3% and the Hang Seng Tech Index 0.7% during the session.

Why did the two IPOs diverge so sharply?

The answer sits in the subscription books, which showed very different demand before either stock traded. Denglin's retail tranche drew 2.11 times its offered shares and its international tranche 1.34 times. Xinde's retail tranche was 9.84 times subscribed, with the international offering 1.13 times covered.

Denglin raised HK$1.41 billion after pricing at the very bottom of its HK$231 to HK$288 range — a signal that institutional buyers would not stretch for the stock. Xinde sold 106.56 million shares near the bottom of its HK$8.60 to HK$9.60 range, raising HK$946.3 million. Pricing at the low end is a common outcome when demand is thin, but Xinde's heavy retail oversubscription carried its shares up on the first day where Denglin's modest coverage could not.

What makes Denglin's listing unusual?

Denglin listed under Chapter 18C, Hong Kong's route for specialist technology companies, and carries a "-P" marker that flags a company which has not yet reached the exchange's commercialization revenue threshold. It is only the third such pre-commercial 18C issuer, according to Phoenix Finance.

The company's financials explain the marker. Revenue was about 170 million yuan in 2025, and its five largest customers accounted for 83% of sales. Denglin says it ranks third in China's enterprise AI GPGPU market by 2025 revenue, holding a 1.0% share — behind two U.S. chipmakers that together control about 95% of that market. In plain terms, the design side of China's AI chip effort remains a distant challenger to the two dominant American suppliers.

Most of Denglin's proceeds will go toward upgrading its GPU products and building new products and software tools. Xinde plans to spend most of its money on production capacity and advanced packaging technology.

What does this say about Hong Kong's chip pipeline?

Chinese chip listings have been a steady part of Hong Kong's IPO pipeline this year, and the flow looks set to continue. Alibaba's chip unit T-Head plans a Hong Kong IPO next year that could raise $2 billion to $3 billion, IFR reported.

The takeaway from Tuesday is that investors are applying real selectivity within the sector. A pre-commercial GPU designer with a 1% market share and concentrated customers was left to sink, while a packaging and test firm with visible capacity plans and heavy retail demand rose sharply — a pattern that will matter to every mainland chip firm now queuing for a Hong Kong listing.
