Sony Music Entertainment (Japan) and Sony Pictures Entertainment Announce the Completion of the Acquisition of Additional Equity Interest in Peanuts Holdings LLC

March 3, 2026

Sony Group Corporation

Sony Music Entertainment (Japan) and Sony Pictures Entertainment

Announce the Completion of the Acquisition of Additional Equity Interest

in Peanuts Holdings LLC

Sony Music Entertainment (Japan) Inc. (“SMEJ”) and Sony Pictures Entertainment Inc. (“SPE”), wholly-owned subsidiaries of Sony Group Corporation (“Sony”), today announced that they have indirectly acquired all of the approximately 41% equity interest indirectly held by WildBrain Ltd., a publicly listed Canadian company, in Peanuts Holdings LLC (“Peanuts”), according to the executed definitive agreement previously announced on December 19, 2025. The total purchase price of this acquisition is approximately 630 million Canadian dollars (approximately 460 million U.S. dollars*), subject to customary working capital and other adjustments. As a result of this transaction, together with SMEJ’s previously existing approximately 39% equity interest, SMEJ and SPE now indirectly own an 80% equity interest in Peanuts, and Peanuts has become a consolidated subsidiary of Sony. For details, please refer to the attached press release.

In connection with the completion of this transaction, Sony expects to record a remeasurement gain as operating income in the fourth quarter of the fiscal year ending March 31, 2026, based on the fair value of SMEJ’s previously existing approximately 39% equity interest in Peanuts. Although Sony has included the estimated amount of such gain, approximately 45 billion yen, in its consolidated financial results forecast for the fiscal year ending March 31, 2026, which was announced on February 5, 2026, Sony continues to evaluate the final amount.

* Reference figures calculated based on a rate of 1 Canadian dollar = 0.73 U.S. dollars.
