NEW YORK (Reuters) - SoftBank Group Corp's chip designer Arm Holdings Plc priced its U.S. initial public offering (IPO) at $51 per share on Wednesday afternoon at the top end of its indicated price range, people familiar with the matter said.
The IPO raised $4.87 billion for SoftBank based on 95.5 million shares sold. It infers a valuation on Arm on a fully diluted basis of $54.5 billion, making it the largest stock market debut since electric car maker Rivian Automotive Inc (NASDAQ:RIVN) in 2021.
The sources requested anonymity ahead of an official announcement. Arm did not immediately respond to a request for comment.
