Which company owns the semiconductor designer Arm Holdings after acquiring it in 2016?

SoftBank Group owns the semiconductor designer Arm Holdings after acquiring it in 2016.

SoftBank Group acquired Arm Holdings in 2016 for about £24 billion. Arm designs processor architectures and intellectual-property cores that other companies license for use in chips. Its technology is widely associated with smartphones, tablets, embedded systems, and increasingly data-center and artificial-intelligence applications.

Arm was founded in 1990 as a joint venture involving Acorn Computers, Apple, and VLSI Technology. It became a public company in 1998 before SoftBank took it private. Arm returned to the public markets in 2023, with SoftBank retaining a controlling stake after the initial public offering.

SoftBank Group is often confused with SoftBank Corp., a separately listed Japanese telecommunications company. The group is an investment and holding company with stakes in technology businesses, while SoftBank Corp. primarily operates communications and related services. Their names are related but their securities and corporate structures differ.
