Nidec Corporation (TOKYO: 6594; OTC US: NJDCY) (the “Company”) hereby announces that the scheduled disclosure date of the financial results for the third quarter of the fiscal year ending March 31, 2026, will exceed 45 days after the quarter-end, as detailed below.

We sincerely apologize for any inconvenience and concern caused to our shareholders, investors, and other stakeholders.

1. Reason for the Delay in the Disclosure of the Financial Results

As announced in the press release dated September 3, 2025, “Notice Regarding Establishment of Third Party Committee,” suspected improper accounting practices involving or recognized by the management of the Company or its group companies were found, and these practices, including arbitrarily adjusting the timing of write-downs of certain assets with risk in terms of their asset value, may impose a material impact on the Company’s overall consolidated financial statements. Thus, the Company determined that it would need to launch an objective investigation by an independent third-party committee, and established such a committee on September 3, 2025, in accordance with the “Guidelines for Third-Party Committees in Cases of Corporate Misconduct” established by the Japan Federation of Bar Associations. The Company commissioned to the thirdparty committee: fact-finding investigations into suspected improper accounting practices; calculation of the amount of impact if improper accounting is found; root cause investigations and recommendation of recurrence prevention measures if improper accounting is found; and other matters deemed necessary by the third-party committee. The Company fully cooperates with the Third-Party Committee’s investigations and as part of the third-party committee’s investigation, gathers information via voluntary inspection under the management and supervision of the third-party committee and collaborates with it. In addition, the Company has been conducting internal investigations to the various issues concerning trade transactions and customs.

The investigations by the Third-Party Committee and other internal investigations are ongoing. If any misstatements are identified as a result of the investigations, they could have a material and pervasive impact on the condensed quarterly consolidated financial statements.

The Company has been informed by the Third-Party Committee about (1) The results of the investigation as of that point in time, including cause investigations and recommendation of recurrence prevention measures will be submitted by around the end of February 2026, and (2) The results of final calculation of the amount of impact etc., will be resubmitted thereafter.

In light of the progress of the investigation, the disclosure of the financial results for the third quarter of the fiscal year ending March 31, 2026, will be postponed. The Company believes that finalizing the figures of financial statements upon the completion of the investigation by the Third-Party Committee and other internal investigations, receiving interim review by the Accounting Auditor and providing proper and high-reliability information contribute to the decisions made by our shareholders. As a result, the scheduled disclosure date of the financial results for the third quarter of the fiscal year ending March 31, 2026, will exceed 45 days after the quarter-end.

2. Future Disclosure Schedule

The new disclosure date for the financial results for the third quarter of the fiscal year ending March 31, 2026, will be announced promptly once determined.

The Company will promptly proceed with the procedures for the financial results upon receiving the investigation report from the Third-Party Committee and the completion of other internal investigations.
