Stock Soars 1200% on First Day, 80s Sales Engineer's Reversal: From Selling FRP to a Fortune of 29 Billion
On its first day of listing, Zhenbao Technology (stock code "N Zhenbao") surged by 1207%, marking itself as the second "ten-bagger" new stock of the year on the STAR Market. The closing price of 585 yuan propelled it into the top 20 of the A-share market by stock price. Dubbed the "first share of semiconductor consumables," the company is backed by a comprehensive shareholder list including National Integrated Circuit Industry Investment Fund Phase II, SMIC, BOE, and YMTC. Zhenbao's business model focuses on supplying critical consumable components like silicon rings and quartz parts to semiconductor fabs. Unlike expensive core equipment with low repurchase rates, these consumables require frequent replacement as long as production lines are running, generating stable recurring revenue—a key reason for its high market valuation.
Founder Wang Bing, an 80s-born former sales engineer, built the company by identifying a supply chain vulnerability: foreign monopolies on high-purity materials led to high costs and unstable deliveries for domestic fabs. Zhenbao's strategy emphasized reliability and speed over absolute top-tier performance, offering products at about 50% of the price with 80% of the performance but 100% on delivery and responsiveness. To achieve this, the company vertically integrated its operations across "raw materials + components + surface treatment," ensuring supply chain control and cost reduction. Its clientele now spans major domestic fabs like BOE and Huahong, as well as international players like SK Hynix and Texas Instruments.
However, risks accompany its rapid expansion. The IPO raised approximately 1.605 billion yuan primarily for capacity expansion, which will bring significant annual depreciation costs, potentially impacting future profitability. The company's growth is heavily reliant on sustained high levels of fab expansion, making it vulnerable to the semiconductor industry's cyclical downturns. Other concerns include high accounts receivable (70.83% of revenue at one point in 2025), heavy reliance on its top five customers (over 70% of sales), and questions about the stability and authenticity of its R&D investments, evidenced by volatile R&D headcount and unusual spikes in R&D energy consumption. While the "consumables story" commands a premium, long-term valuation will depend on maintaining high capacity utilization and healthy cash flow conversion.
