As announced in the “Notice regarding consideration of an application for approval of an extension of the filing deadline of Annual Securities Report for the 53rd Fiscal Year (Ended March 31, 2026)” dated June 16, 2026, Nidec Corporation (TOKYO: 6594; OTC US: NJDCY) (the “Company”) had been considering filing to the Kanto Local Finance Bureau an application for approval of an extension of the filing deadline for Annual Securities Report for the 53rd Fiscal Year (Ended March 31, 2026) prescribed in Article 15-2, Paragraph (1) of the Cabinet Office Ordinance on Disclosure of Corporate Affairs. Accordingly, at the Board of Directors meeting held today, the Company resolved to file an application for approval of an extension of filling deadline of Annual Securities Report for the 53rd Fiscal Year (Ended March 31, 2026) and has completed the filing of an application for such extension to the Kanto Local Finance Bureau. Details are as follows:

1. Annual Securities Report covered
   Annual Securities Report for the 53rd Fiscal Year (Ended March 31, 2026)
   (From April 1, 2025, to March 31, 2026)
   
   
2. Deadline for filing before an extension
   June 30, 2026
   
   
3. Deadline for filing if an extension is approved
   September 30, 2026
   
   
4. Reasons for an extension of the filing deadline
   As announced in the “Notice regarding consideration of an application for approval of an extension of the filing deadline of Annual Securities Report for the 53rd Fiscal Year (Ended March 31, 2026)” dated June 16, 2026, based on the investigation by the third-party committee, the Company is proceeding to finalize prior consolidated financial statements and the impact on prior financial statements, considering various factors, including whether to recognize additional impairment losses on goodwill and fixed assets and currently conducting verification regarding tax expenses and other related impacts for corrections to past fiscal years’ financial results and financial closing for the fiscal year ended March 31, 2026.
   In addition, as announced in the “Notice Regarding Potential Quality Issues and Establishment of an Investigation Committee Composed of External Experts,” dated May 13, 2026, it was identified that there were suspicions of inappropriate conduct by the Company and its group companies, including changes to materials, processes, and designs for certain products without customer approval, improper handling of testing and inspection data, and improper labeling of production locations. As of the same date, the Company established an Investigation Committee composed of external experts. The investigation by the Investigation Committee is expected to be completed by the end of August 2026. Based on the results, the Company is required to examine the impact of potential product quality issues on its financial performance.
   Furthermore, regarding the unpaid customs duties at the Company’s consolidated subsidiary, NIDEC FIR INTERNATIONAL S.R.L. (hereinafter, "FIR"), the Company has continued to expand the scope of the investigation into transactions with the U.S. within the group companies, excluding FIR and has also been conducting a review of non-U.S. transactions in parallel. If the investigation reveals any further additional customs duties, the Company will need to evaluate the financial impact of such customs duties.
   These investigations and related matters are still ongoing, and it is expected that they will require a considerable amount of time to be completed. In addition, after completion of the investigations, the Company’s closing related procedures based on the results thereof and the audit procedures by the accounting auditor are also expected to require a considerable amount of time. Accordingly, the Company has determined that it is difficult to file Annual Securities Report for the 53rd Fiscal Year (Ended March 31, 2026) after receiving the audit report by the statutory filing deadline, and has therefore decided to apply for approval of an extension of the filing deadline for Annual Securities Report for the 53rd Fiscal Year (Ended March 31, 2026).
   
   
5. Future outlook
   If an application for approval of an extension of the filing deadline of Annual Securities Report for the 53rd Fiscal Year (Ended March 31, 2026) is approved, the Company will promptly disclose this information.
