Notice Regarding Final Estimate of Proportion of Distributed Assets Related to Spin-off of Financial Services Business

September 17, 2025

Sony Group Corporation

Notice Regarding Final Estimate of Proportion of Distributed Assets

Related to Spin-off of Financial Services Business

As disclosed in the announcement entitled “Resolution for Execution of Partial Spin-off of Financial Services Business” on September 3, 2025, Sony Group Corporation (“Sony”) resolved at a meeting of Sony’s Board of Directors held on the same date to execute a partial spin-off (the “Spin-off”) of Sony Financial Group Inc. (“SFGI”), a wholly-owned subsidiary of Sony, which operates the Financial Services business, effective October 1, 2025. The proportion of distributed assets pertaining to the Spin-off, by way of distribution of dividends in kind, for Japanese tax purposes is expected to be finalized as follows.

Proportion of distributed assets (final estimate): “0.206”

The proportion of distributed assets is a factor necessary for calculating the acquisition cost per share for common stock of Sony (“Sony share(s)”) and common stock of SFGI applicable to shareholders for Japanese tax purposes immediately after the Spin-off. The proportion of distributed assets will be finalized when the dividends in kind become effective. However, because Sony currently does not expect any changes to the above proportion until the dividends in kind become effective, Sony hereby announces the final estimate. For the finalized proportion, please refer to the notification expected to be sent around early November 2025 to Sony’s shareholders as of the record date for the dividends in kind, September 30, 2025. For details about the proportion of distributed assets, please refer to the “Q&A for the Partial Spin-off of the Financial Services Business (Updated version)” dated August 28, 2025.

For details of the Spin-off, including tax treatment related to the dividends in kind and treatment for holders of American Depositary Receipts of Sony shares, please refer to the following materials available on Sony’s website.
