British chip designer Arm, owned by SoftBank Group, is embarking on a major initial public offering (IPO) in the U.S., targeting a valuation exceeding $52 billion. The IPO includes the offering of 95.5 million American depository shares with a price range of $47 to $51 each, potentially raising up to $4.87 billion. SoftBank will retain 90.6% of Arm's ordinary shares post-offering, with proceeds not going to the Japanese conglomerate. Arm has secured key clients, including Apple, Nvidia, Alphabet, Advanced Micro Devices, Intel, and Samsung Electronics, as investors in its IPO.
