What happened
On September 6, CATL announced via its official WeChat account that it had signed a strategic cooperation agreement with Taijin New Energy (688813). The next day, Taijin's stock price rose sharply, closing at the daily limit of 122.77 yuan per share, a 20% increase for the day.
On the evening of September 7, Taijin New Energy disclosed a trading risk warning, noting that its stock saw a turnover of 1.01 billion yuan and a turnover rate of 28.9% that day, due to its relatively small float. The company highlighted the agreement is framework-based and non-binding, with no specific transaction amounts or mandatory purchase obligations.
Taijin New Energy also reported a decline in its 2026 half-year revenue by 11.5% year-on-year and a 16.44% drop in net profit attributable to shareholders, attributing the downturn to industry overcapacity and reduced order intake.
Why it matters
The partnership with CATL, a major battery maker, could signal strategic collaboration in equipment supply and technology upgrades, but the lack of concrete orders means the financial impact remains uncertain.
The stock's sharp rise and high turnover rate indicate speculative trading, especially given the company's small float and valuation metrics significantly above industry averages, posing potential risks for investors.
