China’s drive toward semiconductor self-sufficiency has created massive opportunities for homegrown chip material suppliers. Hubei Dinglong is one company riding that wave, with its Shenzhen-listed shares skyrocketing over 116% in the past year. That stunning rally has officially made its two co-founding brothers billionaires.
Who Are the Brothers Behind Hubei Dinglong?
Zhu Shuangquan, 61, serves as chairman, while his younger brother Zhu Shunquan, 57, leads the company as CEO. Each brother holds roughly a 15% stake in the business. Forbes puts their individual net worth at approximately $1.3 billion based on recent share prices.
The Business That Built Their Billion-Dollar Fortune
Hubei Dinglong has built its reputation as China’s go-to provider of chemical mechanical polishing materials. This process smooths silicon wafer surfaces so circuits can be printed and chips can be stacked efficiently. The company claims to be the only Chinese supplier offering the complete range of these specialized materials.
Expanding Into New Semiconductor Territories
After the U.S. tightened chip-related export controls on China in 2022, Dinglong wasted no time expanding into lithography materials. It now manufactures photoresist, a key chemical used to imprint circuit designs onto silicon wafers. The company has also moved into advanced semiconductor packaging materials, broadening its footprint across the chip supply chain.
Impressive Financial Growth Powering the Stock Rally
In early 2026, the company’s net profit jumped 78% year-on-year to around $36.9 million on revenues of $147 million. Semiconductor-related businesses now account for more than half of total annual revenue. Those numbers have given investors plenty of reasons to keep pushing the stock higher.
From State Employees to Self-Made Billionaires
The brothers didn’t start in semiconductors — they previously managed state-owned enterprises before co-founding Dinglong back in 2000. Their original goal was reducing China’s dependence on foreign chemical imports, starting with printer toner chemicals dominated by Japanese and Western giants. That same competitive hunger eventually steered them toward the far more lucrative semiconductor materials market.
A ‘Burn the Boats’ Mentality That Paid Off
Their journey is a powerful reminder that bold vision and relentless execution can build empires. Shuangquan once described their early days as running purely on drive, courage, and market instinct with very little else to lean on. Dinglong never lost that spirit — and today, it is paying off in billions.
