Chinese EV battery giant CATL and Guoxin Micro set up new automotive chip firm
The two companies expect to launch Tongxin Micro Technology as a developer of automotive domain controller chips

With its 153 million yuan investment, Tongxin Micro holds a controlling 51 per cent stake in the new firm, while Wending Investment’s 15 million yuan outlay gave it a 5 per cent shareholding, according to the filing.
The newly formed entity was set to acquire the automotive domain controller chip business from Tongxin Micro for 193 million yuan. Based on the asset’s book value, that price represented an appraised appreciation rate of 3,723 per cent.
The automotive domain controller chip business would require significant capital investment and a long investment cycle, Guoxin Micro said in its filing. “By introducing external investors, the company will only bear losses in proportion to its equity stake.”
