Nidec hit by accounting crisis, delisting risk; robot demand offers brief lift

Humanoid robot supply-chain optimism Nidec shares briefly rallied on hopes that demand from humanoid robot makers would boost sales, as Nidec supplies many robot companies. But the lift was speculative and faded with AI-related valuations.
This was the only positive force during the quarter, though temporary.
Accounting and governance crisis Nidec delayed its annual securities report, missed its April–June earnings deadline, and disclosed 844 quality misconduct cases, including 60 serious ones. An external panel blamed weak controls and short-term target pressure.
This was the core negative event that dominated the quarter and damaged investor trust.
Shareholder lawsuit and leadership turmoil A shareholder derivative suit seeks ¥28.7 billion from founder Shigenobu Nagamori and former directors. Later, Nidec confirmed the president’s resignation, adding to leadership uncertainty.
These events deepened the governance crisis and raised concerns about management stability.
Massive impairment, loss, and delisting risk Nidec confirmed a possible ¥1 trillion impairment, a ¥496 billion pretax loss, weak FY2027 guidance, and a second auditor disclaimer from PwC Japan. Delisting risk intensified, and shares fell sharply.
These financial and regulatory blows directly caused the stock’s sharp decline and heightened delisting fears.

Nidec's ¥632B fraud loss, auditor disclaimer, and delisting risk crush shares

¥1 trillion impairment and president's dismissal confirmed Nidec admitted it is considering a massive write-down of about ¥1 trillion and executive changes, including removing its president. A write-down that size would erase roughly a decade of profits, so investors sold the stock hard, with shares falling as much as 18%.
This is the first concrete confirmation of the scale of the financial damage and the leadership shake-up, directly driving the sell-off.
President resigns; EV business impairment balloons President Kishida resigned immediately, and the EV-related impairment is now expected to far exceed the earlier ¥250 billion estimate. A sudden leadership exit and a much larger loss than guided add uncertainty and weigh on the shares.
The resignation and the ballooning EV loss are new events that increase uncertainty and confirm deeper problems than previously disclosed.
FY2026 pretax loss of ¥496 billion; weak FY2027 guidance Nidec reported a ¥496 billion pretax loss for the year ended March 2026, far worse than analysts expected, and guided next year's profit 23% below consensus. The huge loss and weak outlook show the damage is not contained and future earnings will suffer.
The actual loss and disappointing guidance quantify the financial hit and signal a slow recovery, pushing the stock down.
Auditor disclaimer and delisting risk hit year-to-date low PwC Japan refused to give an opinion on Nidec's financial statements for a second straight year, saying it lacked enough evidence. With the Tokyo Stock Exchange reviewing whether to delist the company, shares fell nearly 20% to a year-to-date low as investors fear the stock could be removed from the exchange.
The auditor's disclaimer and the imminent delisting review are the most severe regulatory threats, directly causing the stock's plunge to a new low.

Nidec's governance crisis deepens: delayed filings, 844 quality cases, derivative suit

Annual report filing delayed to September 30 Nidec asked regulators to push its annual securities report deadline from June 30 to September 30 because investigations into past financial statements, product quality and unpaid customs duties are taking too long. A delayed report signals serious compliance problems and keeps investors in the dark about the company's true finances.
This is the first sign this period that governance problems are delaying required disclosures, a core negative force on the stock.
Humanoid robot supply-chain optimism lifts motor makers Component suppliers like Nidec rallied as investors bet on faster humanoid robot production, since these suppliers sell to many robot makers at once. But the same report warned AI-related valuations may be overextended, so this lift is speculative and could fade.
It is the only positive price driver this period and shows a real demand-side counterweight to the governance news.
April–June earnings release missed Nidec failed to publish its April–June 2026 results within the Tokyo Stock Exchange's 45-day limit because it is still investigating accounting irregularities and quality misconduct. Missing a required deadline adds to the picture of a company whose basic reporting cannot be trusted, weighing on the shares.
It shows the governance problems are now disrupting routine financial reporting, not just past statements.
844 quality misconduct cases and delisting risk An external panel found 844 cases of quality misconduct, including 60 serious ones, blaming pressure for short-term targets and weak quality controls. Nidec is already a special attention stock and could be delisted if it fails to fix internal management within one year, a direct threat to shareholders.
This is the biggest new negative: confirmed widespread misconduct plus an explicit delisting risk that directly threatens the investment.
Derivative suit seeks 28.7 billion yen from founder An individual shareholder sued founder Shigenobu Nagamori and two former directors for about 28.7 billion yen, alleging illegal buybacks and dividends beyond the legal limit. It is the first such suit since the accounting fraud surfaced, raising the risk of more legal claims and further management distraction.
It is a new legal front that could cost the company and its former leaders money and keep governance concerns in the headlines.

ABB raises outlook on record orders, buys Rotork, invests in grid capacity

Q2 orders surge 30%, profit up 7%, 2026 revenue outlook raised ABB's second-quarter orders jumped 30% to $12.0 billion and net income rose 7% to $1.23 billion. Management raised full-year 2026 revenue growth guidance to low double-digit to low-teens, a direct sign that demand for ABB's electrification and automation products is stronger than expected, which supports a higher share price.
This is the single biggest new fundamental driver of ABB's value this period.
ABB to buy Rotork for $5.5 billion, funded partly by Robotics sale ABB agreed to acquire UK actuator maker Rotork for about $5.5 billion, a 60% premium, to expand its automation business. The deal will be paid for with cash and roughly $4.8 billion from selling its Robotics unit to SoftBank. Buying a quality business at a high price is a long-term positive, but the premium and integration risk create some uncertainty for the share price.
This is a major strategic move that reshapes ABB's portfolio and affects its balance sheet.
ABB invests $200 million to expand European medium-voltage manufacturing ABB announced a $200 million investment across Europe, including a new $100 million plant in Italy, to boost production of medium-voltage electrical equipment. This capacity expansion positions ABB to capture rising demand from battery storage and grid projects across Europe, supporting future revenue growth.
It shows ABB is investing to meet the electrification demand that is driving its orders.
ABB invests in Gridcog to scale energy project modeling software ABB made a minority investment in UK startup Gridcog, whose software helps design and compare renewable and microgrid projects. This strengthens ABB's advisory and digital services for commercial and industrial customers, adding a higher-margin software layer to its electrification offerings and supporting long-term growth.
It highlights ABB's push into digital and software services that complement its hardware business.
