The world’s largest EV battery maker is struggling to win investor confidence after losing nearly $100 billion in market value in less than six months.

The market has cooled on China’s Contemporary Amperex Technology Co., or CATL, as higher raw material costs have slashed its profit margins. Over the long term, some investors and analysts question whether CATL’s growth could suffer as competitors rapidly expand and customers try to diversify their supply chains.
