The call

The motors and customer relationships still work; the open accounting scandal and delisting risk are what make Nidec hard to read right now.

Nidec is a Japanese manufacturer of small motors, gearboxes, and mechanical parts used in cars, robots, and appliances across dozens of countries. The company's real strength is 50 years of engineering skill and deep relationships with major automakers, which makes it hard for rivals to replace but not impossible as electric vehicles need fewer parts. The immediate problem is not competition: it is an accounting scandal that forced out the founder and chairman, a massive $2.5 billion accounting loss, and operating profits that crashed 82.5% in the first half of this year, putting the stock on watch for delisting from Japan's stock exchange. Until audited financial results are released in 2026 and the company fixes its internal accounting controls, no one can reliably guess what the company is actually worth.

Why
01
AI pressure: None apparent. AI mostly feeds Nidec here: humanoid robots and data-center cooling need its motors, not the other way around. Could AI do the core job? Unlikely.
02
Bigger players: Automakers and Chinese EV supply chains insourcing e-axle and motor production. Q1 FY2025 alone brought ¥87.6 billion in lost automotive contracts as carmakers pull motor work in-house or to cheaper suppliers. Could a giant copy it? Probably.
03
What protects it. Fifty years of precision motor engineering and Tier-1 relationships across 300+ subsidiaries, hard to replicate fast.
What would change this call
Nidec files audited FY2026 results after repeated postponements. Shows whether the ¥250B writedown is bounded and internal controls are fixed.
Tokyo Stock Exchange lifts or escalates Nidec's special-alert designation. Indicates whether delisting risk is resolved or worsening.
Nidec's quarterly automotive-segment contract losses shrink or keep growing. Shows whether customer defections in automotive are stabilizing or accelerating.
Key numbers
  • Automotive contract losses hit ¥87.6 billion in one quarter (2025-11-14)
  • Operating profit fell 82.5% in H1 FY2025 (2025-09-30)
  • Accounting writedown flagged at roughly ¥250 billion (2026-03-03)
Named risks
  • TSE special-alert status could lead to delisting if internal controls are not remediated. Severity: high
  • Second accounting writedown could materially exceed the Y250 billion warned amount. Severity: high
  • Automotive segment contract losses and impairments continuing quarter over quarter. Severity: high
  • Executive Responsibility Investigation Committee could trigger shareholder or legal claims for FY2020-2025. Severity: medium
  • Activist investor Oasis Management could force breakup or restructuring of core segments. Severity: medium

Questions people ask
Is Nidec Corporation in financial trouble in 2026?
Yes. Nidec postponed its FY2026 results on April 27, 2026 pending accounting corrections, warned of a roughly Y250 billion writedown on March 3, 2026, and saw H1 FY2025 operating profit collapse 82.5% to Y21.1 billion amid an unresolved accounting scandal.
Could AI replace Nidec's motor and gearbox business?
Unlikely directly. Nidec makes physical hardware like motors and gearboxes; AI-driven robotics such as Nvidia's Isaac and GR00T platforms are a demand tailwind for Nidec's precision components rather than a software substitute, per EE Times reporting from July 15, 2026.
Who is Nidec's biggest competitor in robotics gearing?
Harmonic Drive Systems leads strain-wave gearing and Nabtesco leads cycloidal gearing for industrial robots as of 2026, both established specialists that Nidec's newer FLEXWAVE and KINEX gearbox lines are contesting rather than displacing.
Why was Nidec removed from the Nikkei 225 in 2025?
Nidec was expelled from the Nikkei 225 and given Tokyo Stock Exchange special-alert status on October 28, 2025 after an accounting scandal emerged, with a Third-Party Committee investigation launched September 3, 2025 into Group-wide inappropriate accounting.
What caused Nidec's accounting scandal and who was blamed?
A Third-Party Committee report delivered March 3, 2026 found widespread accounting misconduct blamed on founder Shigenobu Nagamori's 'excessive pressure to achieve targets,' leading to his full resignation and the departure of Chairman Hiroshi Kobe and the CFO.
Is Nidec stock a good buy after the 2026 scandal?
Unclear until FY2026 audited results are filed. Nidec's market cap was about Y2.93 trillion on July 24, 2026, with shares trading between Y1,797 and Y3,296 over the prior 52 weeks versus an all-time high of Y7,587.5.
