Nidec Corporation said Nov. 14, 2026, it is considering applying to extend the statutory filing deadline for its 54th fiscal semi-annual securities report by one month to Dec. 16.

The Kyoto-based manufacturer was originally required to submit the financial report covering April 1 through Sept. 30 by Nov. 16 under Japanese corporate disclosure regulations, according to the regulatory filing.

The planned delay follows historical accounting corrections that reduced Nidec's net assets by 476.9 billion yen ($3.1 billion) for past periods through March 31, 2025.

The company is preparing an application under Article 18-2 of the Cabinet Office Order on Disclosure of Corporate Affairs, Nidec Representative Director and Senior Managing Executive Officer Masayuki Minai said in the statement.

The filing cited ongoing administrative bottlenecks in finalizing amended accounting figures across several of its operating locations in North America.

Those unfinalized figures have prevented independent auditor PricewaterhouseCoopers Japan LLC from concluding its interim review procedures within the statutory schedule, the company said.

Nidec filed its annual securities report for the 53rd fiscal year on Sept. 30, 2026, under an auditor disclaimer of opinion from PwC Japan.

A disclaimer of opinion indicates that an independent auditor was unable to obtain sufficient appropriate audit evidence to form an opinion on corporate accounts.

The ongoing review requires Nidec to incorporate complex retroactive revisions from prior fiscal periods into its current semi-annual consolidated financial statements.

Nidec must reconcile multiple overseas ledgers with internal controls established under its business transformation plan, the company said.

The audit firm requested expanded personnel evaluations and internal communications reviews involving dozens of managers and operational executives, extending the timeline for clearance.

The Tokyo Stock Exchange designated Nidec shares as a Security on Special Alert on Oct. 28, 2025, citing internal control deficiencies.

The special alert designation places Nidec under heightened regulatory scrutiny and requires comprehensive proof of internal control improvements to maintain its listing.

Nidec manufactures precision electric motors, automotive drive axles and robotic actuators used across factory automation, hard disk drives and electric vehicles.

Global robot builders and industrial equipment makers maintain long-term supply arrangements with Nidec for harmonic speed reducers and precision joint drives.

The disclosure filing does not state whether the accounting delay will cause shipment disruptions across Nidec's motor manufacturing lines, and the company has not published figures on customer delivery schedules.

The company has not disclosed any cancellation of customer contracts or supplier payment halts resulting from the pending semi-annual report extension.

Automotive components and industrial robotics hardware segments accounted for more than half of Nidec's consolidated net sales in recent annual reporting periods.

Procurement officers at industrial robotics manufacturers track supplier governance closely because regulatory sanctions can complicate vendor certification and financing.

Nidec said its finance departments are working with external accounting advisers to finalize consolidated balance sheets and income statements for the six-month period.

The company plans to submit the formal extension application to the Kanto Local Finance Bureau once internal review procedures conclude.

If the regulatory bureau approves the request, the revised submission deadline for the semi-annual securities report will fall on Dec. 16, 2026.
