A little-known Chinese tape maker that supplies Apple, Tesla and BYD ripped as much as 787% on its first day of trading, underscoring the white-hot appetite for new listings in China’s industrial supply chain and instantly minting two billionaires in the process.
Crown New Materials surges 787% in China IPO debut
Crown New Materials Technology raised 956 million yuan, or about $144 million, in late October after selling 56.3 million shares, and the stock’s explosive debut turned founder Mai Michael and sister Mai Huixia into paper billionaires. The surge shows how investors are rewarding companies tied to global consumer electronics and electric vehicles, even when they are far from household names.
The company makes protective films and adhesive materials used in products linked to Apple, Tesla and BYD, giving it exposure to some of the world’s highest-profile technology and auto brands. That customer base matters because it ties Crown’s growth prospects to demand across premium smartphones, EVs and related manufacturing ecosystems, areas that continue to attract capital despite a slower broader Chinese economy.
Crown, founded in 2000, is also betting its IPO proceeds will help fund a research center in China, according to Forbes. The listing comes as Beijing tightens scrutiny of capital outflows and wealthy families’ offshore structures, while domestic demand remains weak and policymakers are trying to stabilize growth.
The stock’s violent move highlights both the liquidity chasing China’s new issues and the risk of sharp reversals once the first-day excitement fades. For investors, the debut is a reminder that China’s IPO market can still deliver outsize gains, but it also raises the bar for evaluating whether such valuations can hold beyond the initial trading frenzy.
With competition from Japan’s Nitto Denko and 3M abroad and domestic peers such as Shanghai-listed Smith Adhesive New Material and Shenzhen-listed Jiangsu Sidike New Materials Science, Crown will need to prove it can turn its IPO windfall into durable earnings growth. The next test will be whether the share price can stay elevated as the market shifts from debut euphoria to fundamentals.
