Michigan seen among options for Rivian battery plant

Fresh off a $12 billion initial public offering, Rivian Automotive Inc. is investing in a dizzying array of expansion projects, pursuing a site for a stand-alone battery factory in addition to new vehicle-assembly plants already planned. Among the states seen as a possibility is Michigan.

The to-do list for the electric-vehicle maker will be funded in part by its IPO — the sixth-largest in U.S. history. Rivian shares soared 22% Thursday in their second day of trading, creating a stock-market value of more than $100 billion. Two months after delivering its first pickups, largely to employees, Rivian now has a market valuation exceeding that of General Motors Co.

The stock rose 3.1% to $126.81 at 9:45 a.m. Friday in New York.

Rivian’s top investment priority is a second EV manufacturing facility in the U.S., according to people familiar with the matter, followed by a plant in Europe that would start building vehicles by the end of 2023. A site in the U.K. has been under consideration, along with other locations on the Continent, the people said, asking not to be named discussing private information. The cost of the Europe factory would be in the billions of dollars, they said.

Besides Michigan, Arizona and Texas are among the states under consideration for the battery manufacturing site, some of the people said. Irvine, California-based Rivian assembles battery packs using cells from Samsung SDI Co. at the Normal, Illinois, factory where the automaker builds its R1T pickup.

No final decision has been made on any of the sites, the people said. New candidates for the second EV assembly plant in the U.S. have also emerged in recent weeks, some of the people said. Many states are vying for new battery plants as the auto industry shifts toward electrified vehicle lineups. Ford Motor Co. announced plans in September to spend $11.4 billion in Kentucky and Tennessee to build three battery factories and an EV facility. 

The investments add some flesh to Rivian’s bare bones plans outlined in previous statements, filings and news reports. The company had held talks with Forth Worth, Texas, to invest $5 billion in an EV assembly plant, Bloomberg News reported in August. And in an Oct. 1 filing, Rivian disclosed its long-term ambitions about expanding in-house expertise in battery cell production — without saying that included a stand-alone facility.
