In the volatile world of Chinese semiconductors, few stories capture the industry’s boom-or-bust nature as vividly as Shenzhen Demingli. By May 2026, the company’s share price had reached staggering heights, marking a multi-year surge that has left market veterans breathless. This meteoric rise is the result of a high-stakes gamble on the cyclical nature of the global storage market and the sudden explosion of artificial intelligence demand.
The company’s first-quarter earnings for 2026 reveal a financial miracle: revenue jumped fivefold to 7.5 billion RMB, while profits skyrocketed by 50 times to 3.3 billion RMB. Remarkably, the firm generated more profit in these three months than it had in the preceding decade combined. This performance has catapulted founders Li Hu and Tian Hua into the ranks of China’s multi-billionaires, with a combined stake valued at over 50 billion RMB.
Li Hu’s path began in the trenches of Shenzhen’s Huaqiangbei electronics market, a district often dismissed as a hub for mere assemblers and traders. Unlike many of his peers, Li transitioned from trading flash drives to developing proprietary controller chips, a move that required six years of grueling R&D and significant personal financial risk. This technical foundation eventually provided the defensive skill necessary to survive the industry’s brutal downturns.
During the memory industry’s winter of 2023 and 2024, when prices for DRAM and NAND flash plummeted, Li adopted a contrarian philosophy. While global giants like Samsung and Micron cut production to stem losses, Li utilized his firm’s cash flow to stockpile wafers aggressively. By early 2026, Demingli’s inventory had ballooned to over 12 billion RMB, representing more than two-thirds of the company’s total assets.
This hoarding strategy coincided perfectly with the global artificial intelligence explosion. As demand for AI servers surged, manufacturers redirected production toward high-bandwidth memory (HBM), causing a severe supply squeeze for standard memory components. Demingli, sitting on a massive, low-cost stockpile, saw its profit margins swell to nearly 60% as market prices for DRAM nearly doubled in a single quarter.
Despite the current celebration, Demingli’s model remains a high-wire act. With a debt-to-asset ratio nearing 70% and a business model heavily dependent on the price fluctuations of a few global suppliers, the company remains vulnerable. Should the AI frenzy cool or the next cyclical downturn arrive prematurely, the very inventory that made them billionaires could become a liability capable of wiping out their gains overnight.
