SoftBank-backed Arm’s long march to $54.5 billion US listing

(Reuters) – Arm Holdings secured a $54.5 billion valuation in its U.S. initial public offering (IPO) on Wednesday, seven years after its owner SoftBank Group took the chip designer private for $32 billion.

The Japanese investment giant sold 95.5 million American Depositary shares of Arm at $51 apiece to raise $4.87 billion in the listing.

Last month, SoftBank signed a deal to buy the 25% stake it did not already own in Arm from its $100 billion Vision Fund, enabling it to sell fewer Arm shares in the IPO.
