Improving Our Internal Management and Other Systems

On April 17, 20206, Nidec Corporation (the “Company” or “we”) received from the Third-Party Committee, an independent organization, the final version of its investigation report on the suspicion over inappropriate accounting practices at the Company and other Nidec Group companies. The report revealed multiple cases of accounting misconducts, including aversion of recoding expenses and overstatement of profit, at a number of business bases across the Nidec Group.

After receiving the final report, the Company sincerely accepted identified facts, the results of the cause analysis, and suggestions on recurrence prevention, and on April 27, 2026 released a revised, more effective version of its previously-issued improvement plan. Based on this revised plan, we will secure our Company’s organizational diversity and transparency in a comprehensive manner and completely eliminate our old system to strongly launch drastic improvement measures to be reborn as a new Nidec.

To regain trust as quickly as possible, all Nidec Group executives and other employees intend to complete the implementation of this revised improvement plan successfully and dedicate all our strength to having the special-alert status lifted and reviving ourselves in the most expeditious way.
