Nidec Audit Delay Extends Restatement and Earnings Uncertainty

Nidec Delays Restated Financial Reports as Audit Procedures Continue

Nidec Corporation provided an update on October 28 regarding its efforts to resolve the disclaimer of opinion issued by its independent auditor. The company had intended to submit restated financial reports, including its annual securities report for the fiscal year ended March 31, 2026, accompanied by audit reports expressing an opinion, by that date. However, additional verification procedures and audit work remained incomplete, preventing submission. The company has not determined when the audit will be completed or when the restated reports will be filed. The delay leaves the timing of the company's revised financial disclosures uncertain while outstanding accounting and internal management issues continue to be examined.

Accounting Misconduct and Insufficient Audit Evidence

During the audit for the fiscal year ended March 31, 2026, some officers and employees involved in improper accounting practices continued to occupy positions of responsibility in financial reporting. Evaluations of their involvement and remedial measures, including reassignment, were also incomplete. Separately, the independent auditor could not obtain sufficient appropriate audit evidence regarding the amounts of impairment losses and the periods in which those losses should have been recognized. These unresolved matters contributed to the disclaimer of opinion. The issues involve both the company's handling of personnel connected with accounting misconduct and the auditor's ability to verify material financial reporting judgments, leaving further work necessary before the restated reports can be submitted with an audit opinion.

Expanded Personnel Verification and Additional Audit Procedures

To address the outstanding concerns, Nidec has been evaluating and reassigning personnel involved in accounting misconduct while checking the eligibility of their successors. However, the independent auditor's review of emails and other information identified additional matters requiring verification concerning officers and employees in key positions. Consequently, Nidec expanded the scope of its checks. The company plans to complete its currently planned additional procedures by the end of November and report the results to the auditor, provided no further or modified procedures become necessary. Nidec explicitly clarified that this target concerns completion of the planned additional procedures only; it does not mean the audit itself will be completed or the restated financial reports will be submitted in November.

Impairment Losses to Be Reassessed Across Earlier Fiscal Years

Nidec also plans to revise the timing of certain impairment losses recorded in the fiscal year ended March 31, 2026. Some of those losses are expected to be recognized in the fiscal year ended March 31, 2025, or in even earlier periods, rather than remaining entirely in the 2026 fiscal year. The company has completed its restatement work for the fiscal year ended March 31, 2026, and the resulting revisions are undergoing an audit. However, verification and discussions about the amounts attributable to each earlier fiscal year remain ongoing. The final allocation of impairment losses across reporting periods therefore remains subject to further examination, and the company has not established a definitive completion date for the overall audit and reporting process.

Tokyo Stock Exchange Submission and Special Alert Review

Nidec plans to submit a Written Confirmation of Internal Management System to the Tokyo Stock Exchange on October 30. The submission is intended to disclose the status of the development and operation of the company's improvement measures. Following the submission, Nidec will undergo the exchange's review, with the aim of having its Security on Special Alert designation lifted. The planned filing and subsequent review represent a separate but related element of the company's response to its internal management issues. The designation will not be lifted automatically upon submission, because the exchange's review remains necessary. The outcome and timing of that review have not been established in the company's update.

Fiscal 2027 Financial Results Release Date Remains Undecided

Nidec is also preparing its first- and second-quarter financial results for the fiscal year ending March 31, 2027. However, the company has not determined when those results will be released. The unresolved audit procedures, planned financial restatements, and continuing verification of impairment losses remain important elements of its broader financial reporting situation, although the company has not specified a release date for the quarterly results. Investors and other stakeholders must therefore distinguish between the company's stated targets for completing additional verification and its separate, still-undecided reporting milestones. The end-of-November target applies to the currently planned additional procedures, subject to possible changes, and should not be interpreted as a confirmed deadline for the audit or financial disclosures.

Key Dates and Outstanding Reporting Milestones

Industry Impact & Outlook

Nidec's unresolved audit and financial restatements underscore how accounting-control weaknesses and insufficient audit evidence can delay corporate disclosures, complicate assessments of financial performance, and prolong uncertainty for investors, creditors, and business partners. The planned reassessment of impairment losses across earlier fiscal years may also change how stakeholders interpret the company's reported results for individual reporting periods, although the final amounts remain under review. The next important developments are the planned October 30 internal management submission, the Tokyo Stock Exchange's subsequent assessment, and the results of additional verification targeted for completion by the end of November. These milestones may clarify progress toward remediation, but neither the audit completion date nor the timing of revised and quarterly financial disclosures has been confirmed.

Frequently Asked Questions

Why has Nidec delayed its restated financial reports?
Nidec delayed its restated financial reports because additional verification procedures and audit work were incomplete as of October 28, 2026. The company had planned to submit its revised reports, including its annual securities report for the fiscal year ended March 31, 2026, with audit reports expressing an opinion. However, unresolved questions about personnel involved in improper accounting practices and insufficient audit evidence concerning impairment losses prevented submission. Nidec has not announced a confirmed date for completing the audit or filing the restated reports.

What caused the independent auditor to issue a disclaimer of opinion?
The disclaimer of opinion arose from unresolved accounting-control concerns and insufficient appropriate audit evidence regarding impairment losses. Some officers and employees associated with improper accounting practices continued to hold financial reporting responsibilities while assessments of their involvement and remedial measures remained incomplete. The auditor also could not obtain sufficient evidence to verify the amounts of impairment losses and the periods in which they should have been recognized. These issues required additional verification and audit work before the company could proceed with its planned restated financial disclosures.

Will Nidec complete its audit by the end of November 2026?
Nidec has targeted the end of November 2026 for completing its currently planned additional verification procedures, provided no further or modified procedures become necessary. This target does not represent a confirmed deadline for completing the audit. After the planned procedures, the company intends to report the results to its independent auditor, while outstanding audit requirements may still affect the overall timeline. Nidec has specifically clarified that the November target does not mean the audit will be completed or the restated financial reports will be submitted during that month.

How will Nidec revise its impairment losses?
Nidec plans to restate certain impairment losses recorded in the fiscal year ended March 31, 2026, so that they are recognized in the fiscal year ended March 31, 2025, or earlier periods. The company has completed its restatement work for the 2026 fiscal year, and the revisions are being audited. However, verification and discussions concerning the amounts attributable to each earlier fiscal year are continuing. The final allocation of these impairment losses across reporting periods therefore remains subject to further review, and the company has not announced a definitive completion date for the broader reporting process.

What is Nidec submitting to the Tokyo Stock Exchange on October 30?
Nidec plans to submit a Written Confirmation of Internal Management System to the Tokyo Stock Exchange on October 30, 2026. The document is intended to disclose the status of the development and operation of the company's improvement measures. After submission, Nidec will undergo the exchange's review as it seeks to have its Security on Special Alert designation lifted. The planned filing is an important procedural step, but it does not guarantee that the designation will be removed. The exchange's review must take place, and the outcome and timing have not been confirmed.

When will Nidec release its first- and second-quarter fiscal 2027 results?
Nidec has not determined the release dates for its first- and second-quarter financial results for the fiscal year ending March 31, 2027. The company has stated that it is preparing these results, but it has not provided a confirmed publication schedule. Its ongoing audit procedures, financial restatements, and impairment-loss verification remain important parts of its broader reporting situation, although Nidec has not specified a definitive connection between these matters and the quarterly release dates. Stakeholders should therefore treat the timing of both quarterly disclosures as undecided until the company announces further information.
