Arm, the U.K.-based chipmaker owned by Japan’s SoftBank since 2016, has filed for a Nasdaq listing five months after announcing it had filed confidential, preliminary IPO paperwork with U.S. regulators.

The outfit didn’t provide a projected share price in its F-1 paperwork, but SoftBank recently bought the 24.99% stake in Arm that it didn’t own outright from its Vision Fund unit, reportedly at a valuation of more than $64 billion. That’s twice the $32 billion SoftBank paid for Arm seven years ago.
