Chinese auto maker BYD Co. reported a 27.5% decline in net profit in the third quarter, alongside a jump in operating income.

The Shenzhen-based electric-vehicle and battery maker said in a filing to the Hong Kong bourse Thursday that net profit declined to 1.27 billion Chinese yuan (US$198.7 million) from CNY1.75 billion a year ago.

Operating income rose 22% to CNY54.31 billion.

BYD, backed by Warren Buffet's Berkshire Hathaway, said that in the first three quarters of the year, revenue from operations rose 38% to CNY145.19 billion, largely due to increases in its auto and mobile phone businesses. Net profit through September was CNY2.44 billion, down from CNY3.41 billion a year ago.

BYD is a major player and Tesla rival in China, one of the world's largest markets for electric vehicles.
