Thiel-Backed Lithium Miner Is Said to Prepare Nasdaq Listing

Rock Tech Lithium Inc. is preparing a Nasdaq listing to broaden its investor base and help finance a $545 million battery-metals smelter in Germany near sites of key suppliers and customers including Tesla Inc. and BASF SE, according to people familiar with the matter.

The U.S. stock market presence would complement Rock Tech’s listings on the Toronto and Frankfurt exchanges and is linked to a planned equity raise next year, said the people, who asked not to be identified because the talks are private.
