Notice of Partial Amendment

to the “Notice Concerning Equity-Method Affiliates (Transfer to Consolidated Subsidiary)”

As announced in the news release of “Notice Concerning Equity-Method Affiliates (Transfer to Consolidated Subsidiary)” on December 16, 2025, Honda Motor Co., Ltd. (“Honda”) resolved to acquire an additional 21% equity interest in Astemo, Ltd. (“Astemo”), an equity-method affiliate, from Hitachi, Ltd. (“Hitachi”) and to make Astemo a consolidated subsidiary (the “Transaction”), where Honda, Hitachi and JIC Capital Ltd. have agreed on the change in the shareholding structure of Astemo through the Transaction.

Since not all countries’ procedures and measures for approvals from relevant authorities regarding the Transaction have not been completed as of today, Honda changed the scheduled closing date of the Transaction from during the first quarter of the fiscal year ending March 31, 2027 to by the end of the third quarter of the fiscal year ending March 31, 2027.

The Transaction is not anticipated to have a material impact on Honda’s consolidated financial results for the fiscal year ending March 31, 2027.
