BEIJING (Reuters) - Samsung Electronics <005930.KS> is to pay 3 billion yuan ($450 million) for a stake in Chinese automaker and rechargeable batteries firm BYD Co Ltd <002594.SZ> <1211.HK>, the Chinese company said in a stock exchange filing on Thursday.
Automakers and technology companies have formed a series of partnerships in recent years as the race to develop electric, self-driving, internet-connected vehicles has created demand for more electronics components and software.
The Samsung investment has been made through Chinese subsidiary Shanghai Samsung Semiconductor and gives the Korean firm a 1.92 percent stake in BYD, making it the ninth largest investor in the company.
Samsung Electronics said last week it was in talks to acquire a stake in BYD to boost its automotive chip business, after the Korea Economic Daily first reported that Samsung had agreed to buy a stake.
BYD, which also counts Warren Buffet's Berkshire Hathaway <BRKa.N> as a backer, began as a battery maker for personal electronics before launching its automotive business that focuses on electric and hybrid vehicles.
A total of six investors bought BYD shares in a placing at 57.40 yuan per share, a discount to Thursday's closing share price of 61.94 yuan.
The 14.5 billion yuan private placement also included investments by CCB Principal Asset Management, China Life AMP Asset Management, Aegon-Industrial Fund Management and Essence Fund.
