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.

AI demand lifts Delta, but bond overhang and rotation cap gains

AI data-center demand and product ramp Analysts raised 2027 AI spending forecasts, and Delta is ramping its 800-volt power system for NVIDIA's Vera Rubin, positioning it to capture more of the AI infrastructure buildout.
This is the main growth driver behind Delta's business and stock appeal.
Easing shortages and peak Q3 profit Component shortages are easing, and Q3 profit is expected to peak, which supports earnings momentum and gives investors confidence in near-term results.
It explains the improved operational backdrop and profit outlook.
Broker upgrades and improved sentiment Krungsri upgraded the sector and named Delta a top pick, while Bualuang kept a 330 baht target. US-China AI talks and an extended trade truce also lifted sentiment.
These events boosted investor confidence and buying interest.
Exchangeable bond overhang and sector rotation A $1.5 billion exchangeable bond creates a share overhang, capping the stock, which fell 6% on the news. Investors also rotated into KCE and HANA, limiting Delta's rebound.
This is the main counterweight that held back the stock despite positive drivers.

Delta's AI power and cooling orders strengthen as trade tensions ease

US-China AI talks and extended trade truce lift sentiment Trump and Xi held their first talks on AI and extended the trade truce to January 2027. Less chip and trade tension is good for Delta, because its AI data-center power and cooling gear sells into a global build-out that depends on open trade.
New geopolitical de-escalation directly improves the outlook for Delta's AI-linked demand.
AI racks need far more power, raising Delta's content per rack Morgan Stanley raised its power estimate for NVIDIA's next racks, and Bualuang kept a 330 baht target, seeing Q3 sales up 34% year on year. More power and cooling per rack means Delta sells more valuable equipment in each AI data center.
This is the core demand driver behind Delta's earnings growth and stock price.
Delta launches 800 VDC AI data-center system for NVIDIA Vera Rubin Delta unveiled a modular AI data center with 800-volt in-row power and liquid cooling built for NVIDIA's Vera Rubin. Winning a place in the next-generation AI architecture supports future orders and shows Delta's technology is central to the build-out.
A concrete new product tied to NVIDIA's roadmap strengthens Delta's competitive position.
Brokers turn more bullish, naming Delta a top pick Krungsri upgraded electronics to Bullish and picked Delta with a 320 baht target, expecting 51% profit growth in FY27. Kasikorn also named Delta a stock to accumulate on market dips, citing strong AI demand and recovering margins.
Upgraded recommendations and higher targets can pull investor money back into the stock.

Delta's AI power demand stays strong, but bond overhang and rotation cap the stock

AI data-center demand keeps building Delta is ramping raw materials for its new 800-volt AI data-center power system, and analysts say big tech's 2027 AI spending plans are being revised sharply higher. More AI factories mean more orders for Delta's power gear, supporting revenue and prices.
This is the core growth engine behind Delta's earnings and the main reason analysts stay positive.
Supply shortages ease, profit seen peaking in Q3 The component shortages that squeezed Delta earlier in 2026 are easing, and analysts expect third-quarter sales and profit to be the year's best, helped by orders pushed from the second quarter and better margins. That points to a profit recovery.
It explains why earnings are expected to improve after a weak first half, a key support for the share price.
$1.5 billion exchangeable bond creates a share overhang Delta's Singapore unit is issuing $1.5 billion of bonds that can later be swapped into Delta shares at 267-302 baht. No new shares are issued now, but hedging and future selling pressure can cap the stock, which fell about 6% on the news.
This is the clearest new negative force weighing on the share price this period.
Money rotates out of Delta into other electronics names Some investors moved money out of Delta into KCE and HANA, which are seen as having stronger near-term profit prospects, and Delta also tracked its weaker Taiwan parent. This competition for investor money limits how fast Delta can rebound.
It shows a real counterweight: even with good AI news, investor money is choosing other stocks.
