Hubei Dinglong Cofounders Become Billionaires as Shares Rise

Shares of Hubei Dinglong more than doubled in the past year. The increase made cofounders Zhu Shuangquan and Zhu Shunquan billionaires.

Dinglong supplies chemicals used in semiconductor manufacturing. The Wuhan-based company reported first-quarter 2026 net profit of 251 million yuan, up 78 percent from a year earlier. Revenue rose 24 percent to 1 billion yuan. The company said its CMP materials business drove the gains. 7 billion yuan revenue came from semiconductor-related products.

The brothers previously worked at state-owned enterprises before founding the company in 2000. They started with printer chemicals and later moved into semiconductor materials. Hubei Dinglong listed on the Shenzhen stock exchange in 2010. It began supplying CMP materials in 2012 and later added products for advanced packaging and lithography.

The company stated that its photoresist and advanced packaging materials have reached stable small-batch supply. About 70 percent of revenue came from domestic sales.
