Released on June 19, 2024 in Kyoto, Japan

Nidec Corporation (TSE: 6594; OTC US: NJDCY) (the “Company”) announces today that the Company has stated in the internal control report for the fiscal year ended March 31, 2024, submitted on June 19, 2024 to the Kanto Local Finance Bureau in accordance with Article 24-4-4(1) of the Financial Instruments and Exchange Act, that the Company has identified a material weakness and that the Company’s internal control over financial reporting is not effective, as described below. The contents of Section 1, “Details of the material weakness” below are the same as the amended internal control report issued on May 24, 2024 for the fiscal year ended March 31, 2023; however, as the measures have been afterwards implemented to correct and prevent the recurrence of the material weakness, the aforementioned measures are described in Section 3, “Correction policy for the material weakness,” herein.

1. Details of the material weakness
It became clear that, at Nidec Drive Technology, a consolidated subsidiary of the Company, the wrong data was identified for part of the adjustment, such as sales accompanied by transactions between consolidated subsidiaries of the Company’s business group in its consolidated account closing procedure, resulting in sales recorded in an inflated manner. As it became necessary to cancel the sales amount recorded in an inflated manner, the Company came to the conclusion that it should correct the financial results of the fiscal year ended March 31, 2023. The Company’s rules on internal control over its account closing and financial reporting processes are that journals prepared by their issuers must be approved by someone with approval authority. Nonetheless, this error occurred because of insufficient communications among concerned organizations, which led to an insufficient understanding of the proper and comprehensive information that is necessary when identifying cases that require adjustments, and also to an insufficient system to monitor book closing. As a result, the Company was unable to discover this material misrepresentation. This is how the Company decided that this error is a material weakness in the internal control over its account closing and financial reporting processes.

2. Reasons as to why corrections could not be made by the end of the consolidated fiscal year
Corrections could not be made by the end of the consolidated fiscal year because the aforementioned fact became evident after the end of the consolidated fiscal year ended March 31, 2024.

3. Correction policy for the material weakness
The Company sufficiently understands the importance of internal control over financial reporting. Therefore, to correct the material weakness, the Nidec Group decided to promptly design and implement recurrence prevention measures such as a multiple viewpoints-based verification of the book-closing process and having the person with approval authority introduce a stricter approval procedure, to secure the reliability of its financial reporting. Based on this policy, during the period from the end of the fiscal year ended March 31, 2024 to the date of the internal control report, the Company launched the following recurrence prevention measures to correct material weaknesses. 

(1) Thoroughly review consolidated closing entries included in documents disclosed in past fiscal years and in corrected consolidated financial statements, to identify other related issues, and to better process and present accounts.
- The Company conducted a trend analysis of past consolidated closing entries, and a thorough review of the past and current fiscal years’ consolidated closing entries, that have similar features as those with the aforementioned material weakness.

(2) Update the Company’s policy on its consolidated account closing procedure, enhance the system to understand the proper and comprehensive information when identifying adjustment-requiring cases that are related to transactions between consolidated subsidiaries, and hold lectures focused on the verification of consolidated book closing and on the approval process by those with approval authority.
- The Company made a consolidation adjustment manual, and updated its policy for consolidation procedure.
- The Company changed its structure to establish a system where organizations including those other than the accounting department gather information comprehensively.
- The Company held lectures on consolidation procedure.

(3) Enhance the comprehensive monitoring function of the Company’s and its subsidiaries’ accounting and financial managers over the
consolidated account closing procedure, and enhance the reviewing and approval procedures on the coordination of transactions between
consolidated subsidiaries in account closing and financial reporting processes.
- The Company designed a system to comprehensively monitor the consolidated account closing procedure by the Company’s and its
subsidiaries’ accounting and financial managers, and improved its approval procedure.

4. Impact of the material weakness on the Company’s consolidated financial statements
All the necessary corrections attributed to the aforementioned material weakness are reflected in the Company’s consolidated financial statements.
