CATL, whose clients include Tesla, Volkswagen and BMW, booked a net profit of 9.4 billion yuan ($1.30 billion) from July to September, according to a company filing to the Shenzhen stock exchange.

Revenue increased 232.5% in the three-month period to 97.4 billion yuan from a year before, the company said.

The result is largely in line with an estimate provided by the company last week.
