Arm Holdings under US antitrust investigation for chip technology: Bloomberg

• The FTC notified Arm of the investigation earlier this year and demanded the company preserve documents related to its licensing agreements
• A significant portion of Arm's revenue comes from licensing its chip technology to major companies like Nvidia and Apple, plus collecting royalty payments on design use
• Regulators outside the U.S., including South Korea's antitrust regulator, are also investigating Arm's licensing practices as part of broader global scrutiny

SUMMARY

Arm Holdings is under antitrust investigation by the U.S. Federal Trade Commission (FTC) over potential anticompetitive practices in its semiconductor technology licensing business, Bloomberg News reported on May 15.

Key Investigation Details:

The FTC is examining whether Arm is attempting to illegally monopolize segments of the semiconductor market. Specifically, regulators are assessing if the British chip designer plans to reject or downgrade licensing agreements for its chip blueprints used in central processing unit (CPU) design. The FTC notified Arm of the investigation earlier this year and has demanded the company preserve relevant documents.

Business Model Impact:

A significant portion of Arm's revenue derives from licensing its technology to major companies including Nvidia and Apple, along with collecting royalty payments on design usage. This investigation could potentially affect these critical business relationships and revenue streams.

Global Regulatory Scrutiny:

The U.S. probe is part of broader international scrutiny of Arm's business practices. South Korean antitrust regulators investigated Arm's Seoul offices in November, also focusing on the company's licensing practices.

Market Implications:

This investigation poses significant risks to Arm's business model, which relies heavily on licensing agreements with major semiconductor companies. Any regulatory action could force changes to Arm's licensing terms or practices, potentially impacting revenue and relationships with key clients. The investigation adds regulatory uncertainty for investors in both Arm and companies dependent on its technology.

Neither Arm nor the FTC provided immediate comment on the report, which Reuters could not independently verify.
