Five cornerstone investors hold about 45.7% of Denglin's offering under a six-month lock-up, so the free float is thin while two new 2026 customers drive most revenue.
Suzhou Denglin Technology, a designer of general-purpose graphics processors (GPUs) for AI, closed its first day of trading in Hong Kong at HK$213, 7.8% below its HK$231 offer price, Sing Tao Daily reported in its November 10 market wrap. Jiangsu Xinde Semiconductor Technology, a chip packaging and testing company that listed the same morning, finished at HK$11.40, 28.4% above its HK$8.88 offer price. Together the two companies raised HK$2.36 billion, Reuters reported, according to a copy published by The Standard.
Denglin, which trades under the code 9917, had already priced at the bottom of its HK$231 to HK$288 range. It sold 6,125,000 H shares for gross proceeds of HK$1.4149 billion and net proceeds of HK$1.3124 billion, according to the allotment results reported by China Economic Net. The stock opened at HK$229, touched HK$211 and never regained its offer price during the session.
The split result came on a firm day for the wider market. The Hang Seng Index rose 108 points to 24,557 and the Hang Seng Tech Index gained 1.1%, Sing Tao reported.
Retail demand for Denglin was among the weakest of the year
Hong Kong retail investors subscribed for 2.11 times the shares on offer to them, and the international tranche was covered 1.34 times, Sing Tao reported in a separate story. It said the retail multiple ranked third-lowest among Hong Kong listings in 2026, and that Denglin had closed 4.3% down in grey-market trading the evening before the debut. Turnover on the first day was HK$143 million, according to on.cc.
Xinde drew far stronger interest. Its shares opened at HK$10.70, 20.5% above the offer price, and rose as high as HK$12.65 during the day, on.cc reported. The packaging firm raised HK$946.3 million, pricing near the bottom of its range, and plans to spend most of the money on capacity and advanced packaging technology, Reuters reported.
Cornerstone investors took a large share of Denglin’s offering. Five of them were allotted 2,798,025 shares, about 45.7% of the initial offering, with a six-month lock-up, according to the allotment figures and 21st Century Business Herald. The biggest allocations went to Hua Yuan (华圆), with 1,516,450 shares, and Sky Giant (钜天投资), an indirect subsidiary of chip packager Tongfu Microelectronics, with 1,000,875 shares. Everbright Wealth Management (光大理财), ZGD Capital and a Chinese consortium (中方财团) took smaller amounts.
Fast revenue growth rests on a few new customers
Denglin’s revenue rose from RMB27.9 million in 2023 to RMB171.3 million in 2025, and reached RMB200.4 million in the first four months of 2026 alone. Its loss narrowed from RMB332.0 million in 2023 to RMB16.5 million in the four months to April 30, China Economic Net reported from the allotment announcement. EastFrontier reported on that trajectory when Denglin passed its listing hearing in October.
The growth is concentrated. Denglin’s two largest customers in the first four months of 2026 were both new that year and together provided 63.7% of revenue, Sing Tao reported. 21st Century Business Herald added that the top five customers accounted for 90.4% of revenue in that period, and that only 40.7% of the RMB267.2 million in receivables outstanding at April 30 had been collected by October 14.
Denglin is still a small player in its market. Citing Frost & Sullivan, a report by Red Star Capital Bureau (红星资本局) carried by The Paper said Denglin ranked third among sellers of AI general-purpose GPUs in China by 2025 revenue, with a 1.0% share. Nvidia and AMD together held 95.4% of that market, Sing Tao reported.
The next test is the lock-up and the 2026 order book
Denglin plans to spend about 35% of its net proceeds on upgrading its existing GPU lines, 25% on new products and 20% on its software toolchain, according to the offering notice reported by Gelonghui when books opened on October 30. TechNode put the expected net proceeds at HK$1.31 billion.
Denglin joins a growing group of listed Chinese GPU designers. Biren and Iluvatar CoreX trade in Hong Kong, while Moore Threads, MetaX and Enflame are listed on Shanghai’s STAR Market, The Paper noted. EastFrontier covered Biren’s planned HK$4 billion placement in October.
With nearly half the shares locked up with cornerstones, trading in the coming weeks will rest on a thin float. The clearest signal of whether the 2026 revenue jump holds will be Denglin’s first results as a listed company, and whether its two new customers keep ordering and paying.
