CATL Shares Fall as Automakers Diversify Battery Suppliers

Shares of Contemporary Amperex Technology Co Ltd (CATL) declined 3.5% in Hong Kong trading on Wednesday, extending a recent selloff fueled by investor concerns that key electric vehicle automakers are actively reducing their reliance on the battery giant.

The drop to HK$498 per share reflects a structural shift in the EV market, where major Chinese carmakers are diversifying their supply chains, potentially eroding CATL's dominant market position and pricing power.

Automakers Seek Alternatives

The immediate trigger for the selloff appears to be strategic moves by several of CATL's major customers to secure alternative battery sources and develop their own technology. This signals a transition from relying on CATL as an exclusive supplier to viewing it as one of several options.

Key developments worrying investors include:

• Li Auto invested RMB 2.65 billion in rival supplier Sunwoda Power. The automaker also announced plans to deploy its own self-developed batteries across its entire vehicle lineup.
• Xiaomi Auto has also moved to diversify by partnering with CALB and Sunwoda on a co-developed battery project.

Implications for CATL

This trend of supply chain diversification among China's fastest-growing EV brands poses a long-term threat to CATL. As customers cultivate relationships with competitors and build in-house capabilities, CATL's ability to command premium prices could diminish.

The growing uncertainty has led to market speculation about potential cuts to CATL's September production schedule and a possible negative impact on its third-quarter net profit. CATL's slide on Wednesday occurred even as the broader Hong Kong market showed strength, with the Hang Seng Index rising 0.5%, indicating the selling pressure was specific to the company.
