Nidec

Phase A — Understand the business

Company Overview

Nidec Corporation (Kyoto; founded 1973 by Shigenobu Nagamori as "Nihon Densan") is the world's largest manufacturer of precision electric motors — anything "that spins and moves." It grew from a hard-disk-drive spindle-motor monopolist into a ¥2.6-trillion diversified motor conglomerate spanning appliances, industrial systems, automotive traction, machine tools, and, latterly, data-center power/cooling. It is a components company, not a brand company: it sells motors, actuators, reducers, inverters, generators and cooling units into OEMs, hyperscalers, appliance makers and automakers, mostly on multi-year supply contracts.

FY2024 (yr-end 31 Mar 2025): net sales ¥2,607,813M (~$17.4B), operating profit ¥237,837M (9.1% margin), net income ¥164,159M, EPS ¥142.88 (post 2-for-1 split Oct 2024). That was a record year on paper — a fact the accounting scandal now calls into question, because the restatement examines FY2020 through Q1 FY2025.

Reporting structure (FY2024 net sales by segment):

• Appliance, Commercial & Industrial (ACIM) — ¥1,052.7B — largest pillar; HVAC, water pumps, infrastructure/commercial motors, home appliances.
• Automotive (AMEC) — ¥664.6B — motors, actuators, e-Axle traction systems; ¥116.3B of that was BEV-related.
• Small Precision Motors (SPMS) — ¥487.9B — HDD spindle motors (¥100.2B, structurally declining) + other small motors (¥387.7B).
• Machinery / Electronic & Optical / Other — ~¥402.6B — machine tools, press machines, precision reducers (Nidec Drive Technology / ex-Shimpo), semiconductor-handling robots.

Under the new Conversion 2027 plan the business is being re-cut into five pillars: Better Life (appliances/commercial), Sustainable Infrastructure & Energy (generators, BESS, data-center power & cooling), Base of AI Society (semiconductor inspection / wafer-transfer robots), Efficient Manufacturing (machine tools, press, precision reducers), and Mobility Innovation (automotive).

Contract structure / concentration. No single customer dominates group revenue; concentration risk is by end-market — appliances (China/US housing & AC cycle), autos (EVEnterprise valueWhat it would cost to buy the whole company: its market value plus its debt, minus the cash you would get with it.

Often very different from market cap. price war (see Lens 5) — a payment-terms flaw that cost ¥36.5B in H1 FY2025 provisions alone.

Coverage-bucket correction. The index files Nidec under "robotics." That is a slice, not the company. Robotics-relevant revenue (precision reducers/harmonic drives via Nidec Drive Technology, semiconductor-handling robots) is a low-single-digit share of a ¥2.6T motor conglomerate. Analyze Nidec as a precision-motor industrial with an AI-infrastructure (data-center power/cooling) option and a robotics-components sleeve — not as a robotics pure-play.

Supply Chain

Map: upstream inputs → Nidec → end customer.

Upstream (into Nidec):

• Rare-earth permanent magnets (NdFeB) — sourced heavily from China; the core input for high-efficiency motors. This is Nidec's own single-biggest chokepoint (Chinese rare-earth export controls hit every motor maker).
• Electrical steel / silicon steel laminations, copper windings — commodity, multi-sourced.
• Power semiconductors (IGBTs/SiC) for inverters and e-Axle — from the likes of Infineon, STMicro, Rohm; SiC supply was a constraint in the EV build-out.
• Machined housings, gears, bearings — in-house plus regional suppliers (the Italian and Chinese plants at the centre of the customs/accounting probe sit here).

Nidec (transformation): motor/actuator/reducer/inverter/generator/CDU manufacturing across Japan, China, Southeast Asia, Eastern Europe (Serbia/Poland auto plants), Mexico, and the US.

Downstream (Nidec → end customer), named:

• HDD spindle motors → Seagate, Western Digital, Toshiba (a shrinking but still cash-generative near-duopoly position; Nidec has historically held ~80%+ of the HDD spindle-motor market).
• Appliance/commercial motors → global AC/appliance OEMs (Whirlpool relationship via the 2018 Embraco compressor acquisition), HVAC and pump OEMs.
• e-Axle / auto → Chinese EV OEMs (Geely/Zeekr adopted the 200kW e-Axle), plus other BEV programs — the customer base that just blew up.
• Data-center power & cooling → hyperscalers and colo operators via Coolant Distribution Units (CDUs) — Nidec's "Project Deschutes 5 CDU" is an Open Compute Project contribution, and BESS power units (e.g. Lithuania's largest BESS project).
• Robotics → industrial/collaborative/humanoid robot makers buy Nidec Drive Technology (ex-Shimpo) FLEXWAVE harmonic reducers and precision gearboxes.

Chokepoints / single-source dependencies:

1. Rare-earth magnets — the structural upstream vulnerability; Chinese export policy is an exogenous kill-switch on motor margins.
2. Its own manufacturing integrity — the quality scandal (96.7% of 1,000+ cases = unauthorised material substitutions) means Nidec is a chokepoint risk to its own customers: an OEM that discovers unapproved material changes may requalify a competitor. This is the rare case where the company itself is the weak link in its customers' supply chains.

Names or it didn't happen — done. This lens is web-derived (no supply-chain.md on disk); treat customer-share splits as directional, not audited.

Competitive Advantages (moats)

Where the moat is real:

• Scale + breadth in precision motors. Nidec is the volume leader across an enormous SKU range; the "all that spins and moves" strategy gives genuine manufacturing scale, process know-how, and a global footprint few can match. In HDD spindle motors it has a near-monopoly (very high share) — a declining but defensible cash cow with extreme switching costs (drives are qualified around the motor).
• Precision reducers / harmonic drives (Nidec Drive Technology). Here Nidec is one of a small oligopoly — alongside Harmonic Drive Systems, Nabtesco, Sumitomo Heavy — that controls the strain-wave/cycloidal reducer supply feeding every articulated robot. High-torque, zero-backlash reducers are a real process moat with long qualification cycles; the harmonic-reducer-for-humanoids sub-market is tiny today (~$39M in 2024) but modelled at ~46% CAGR. This is the genuine "robotics" moat, but it is a rounding error on group revenue.
• M&A integration machine. For two decades the durable edge was operational: buy struggling motor businesses (Sankyo Seiki 2003, Valeo motors, Embraco 2018 at $1.1B, ~70+ deals) and fix them. That was a real, repeatable capability.

Where the moat is weaker than bulls think:

• e-Axle had NO moat. Traction motors for Chinese EVs commoditised almost instantly — "all motor suppliers to Chinese EV manufacturers are currently making losses". Nidec's own CEO branded it a "red ocean." A business you exit at a multi-hundred-billion-yen loss was never a moat; it was a scale trap.
• The integration machine just seized. The scandal is being suspended as a strategy — CEO Kishida says Nidec will halt business acquisitions. If M&A was the moat, pausing it is removing the moat.
• Trust is a component-supplier's moat, and Nidec just spent it. Unapproved material changes are precisely the sin that makes OEM quality teams rip out an incumbent. A precision-components franchise runs on qualification trust; the quality scandal attacks the moat at its root.

Bargaining power: strong over small appliance OEMs and in HDD; weak-to-negative in Chinese EV (buyers held all the cards, hence onerous contracts); improving in data-center cooling if Nidec can establish itself against Vertiv/Schneider (see Lens 7). Over suppliers, Nidec is price-taker on rare earths.

Segments

FY2024 net-sales split (from Lens 1) with direction:

Operating profit by segment is not cleanly sourceable in the web results, and — critically — segment operating income for FY2020–Q1 FY2025 is under restatement (the accounting misconduct specifically inflated inventory/fixed-asset values and deferred costs, which flatters segment operating profit). So: segment operating margins n/a AND under restatement. Group-level tells us enough:

• Group operating margin collapsed intra-year. FY2024 full-year OP was ¥237.8B (9.1%). H1 FY2025 (6 months to Sep 2025) OP was only ¥120.5B, −82.5% YoY on the comparable measure, dragged by ¥87.7B of e-Axle-related significant losses (provision for contract loss ¥36.5B + impairment ¥31.7B + supplier-reimbursement claims ¥19.5B). (Note the −82.5% framing compares against a restated/one-off-heavy base; the level — ¥120.5B in H1 — is the reliable read.)
• The auto segment is the wound; the rest of the portfolio (appliances, HDD cash cow, machinery) remains the ballast keeping the group profitable.

Phase B — Measure performance

Earnings Result (latest print + the forecast the market is watching)

There is no clean "latest print." The FY2026 (yr-end 31 Mar 2026) annual result was postponed while Nidec corrects prior-year statements, and PwC Japan issued a disclaimer of opinion on the FY2025 securities report. This is the single most important line in the earnings picture: the auditor will not opine on the numbers.

What is sourceable:

• FY2024 (record, now suspect): net sales ¥2,607,813M, OP ¥237,837M (9.1%), net income ¥164,159M.
• H1 FY2025 (6M to Sep 2025): net sales ¥1,293.8B; OP ¥120.5B; the ¥87.7B e-Axle hit inside it.
• FY2025 full-year guidance (as maintained): net sales ¥2,600B, OP ¥260B, profit attributable ¥200B. Treat this guidance as aspirational and pre-restatement — it predates the full ¥250B impairment sizing and the quality-scandal fallout.
• Impairment still to land: up to ¥250B (~$1.6B), mainly auto goodwill + fixed assets.
• Balance-sheet / capital-return flags: year-end FY2026 dividend set to ZERO; ¥20M-share buyback cancelled (Oct 2025); net assets down ~¥160.7B as of Q1 FY2025 from the restatement.
• Market reaction (the paradox): despite all of the above, 6594.T is up ~+30.7% YTD 2026 and trades ~¥2,610–2,728 (late Jun/early Jul 2026). The market has, so far, chosen to price a turnaround (exit e-Axle, Conversion 2027, cleaner post-scandal governance) over the tail risk (delisting, deeper restatement). That divergence is itself the trade.

Unusual vs. its own history: a "record" year immediately followed by a disclaimer of opinion, a founder exodus, a suspended dividend and a cancelled buyback is a regime break, not a quarter.

Earnings Calls (sentiment trend)

No transcripts on the shelf; sentiment is reconstructed from public commentary.

• Early/mid FY2023–FY2024 (Nagamori era): aggressive, target-driven — record sales/profit messaging, EV/e-Axle as the growth engine, ROE ≥18% ambition. In hindsight this is the tone the third-party committee blamed for the fraud ("losses are unacceptable" entrenched over years).
• Q1 FY2025 (Jun 2025 quarter, Kishida): pivot language — "Conversion 2027," "convert to a high-profit structure," profitability over growth, cost-cutting. Tone shifts from expansion to repair.
• H1 FY2025 / May 2026 (Kishida): damage-control — "withdraw from the e-axle business, which has become a red ocean"; "suspend business acquisitions"; apology framing around accounting and quality.

The trajectory of what they stopped saying is the signal: the ROE-18%/record-growth/e-Axle-flagship narrative has been fully retired inside ~12 months and replaced by exit, cut, atone. Management credibility is the swing variable — every optimistic statement now carries a governance discount.

Comps

Peer set = global motion/motor/reducer names.

Read: on headline multiples Nidec looks cheap (fwd P/E ~10–14x vs Regal Rexnord ~20x, Nabtesco ~28x; EV/EBITDA ~10.75x vs RRX ~15.5x) — but the "E" is under a disclaimer of opinion. A low P/E on unaudited, about-to-be-restated earnings is not a value signal; it is a governance-risk discount the market is applying correctly. The clean comparison is: peers earn a full multiple on trustworthy books; Nidec earns a haircut because its books are, by the auditor's own admission, not yet trustworthy. EV/Sales ~1.2x is the least-corruptible line and screens reasonable for the asset base — but sales, too, included grants-booked-as-revenue.

Stock-Price Catalysts (moves >5%, ~last 2 yrs — the scandal window)

Web-sourced, directional dates:

• Jan 2024 — profit-forecast cut on China EV price war / e-Axle demand collapse; shipment assumption slashed (from ~949k to ~350k EV motors) — down.
• Sep 2025 — accounting irregularities surface; third-party committee established (3 Sep 2025) — the fuse is lit.
• 28 Oct 2025 — TSE "security on special alert" designation; delisting-risk headlines; buyback cancelled — down.
• Dec 2025 — founder Nagamori resigns as chairman (19–20 Dec 2025) — governance-reset bounce in places.
• 3–4 Mar 2026 — ¥250B / $1.6B impairment warning; yet shares surged on the day ("Nidec Shares Surge Even as Accounting Scandal Fallout Spreads") — the market treating the sizing as clearing air.
• 12–13 May 2026 — quality scandal breaks (unapproved material/process/design changes; 1,000+ cases); shares −18% intraday, steepest in six months — down hard.
• 18 May 2026 — e-Axle withdrawal confirmed.
• 31 May 2026 — CEO signals M&A suspension.
• Also May 2025 — −12% on tariff-evasion (mislabelled motors / customs) disclosure.

What the tape reveals: for the last two years, governance and scandal headlines — not operations — set the price. Impairment sizing is treated as air-clearing (shares can rise on it); new categories of misconduct (quality after accounting) are treated as fresh, unbounded risk (−18%). The market is trading the shape of the scandal, and it re-rates violently on each new revelation. Until the auditor signs, this is an event-driven, headline-whipsawed name — not an earnings-compounder.

Phase C — Judge people & books

Management

• Track record (mixed → tarnished). Founder Shigenobu Nagamori (b. 1944) built Nidec from a garage start-up into a ~$15–20B global motor leader via ~70+ acquisitions over 50 years — a genuinely great industrial builder. But the same drive is now named by the third-party committee as the root cause of the fraud: "excessive pressure to meet performance targets," the belief that "losses are unacceptable" entrenched over years, pushing units to "creative accounting".
• Tenure & succession (a chronic failure). Nagamori spent a decade failing to hand over, repeatedly criticising and reclaiming power from designated successors — most visibly retaking control in 2022 after ~one year under ex-Nissan executive Jun Seki. Mitsuya Kishida became President/CEO in Jun 2024 and, post-scandal, Chairman in Dec 2025; Nagamori exited to chairman-emeritus then resigned that too (Dec 2025). The founder-dependency the market long worried about resolved in the worst possible way — via crisis, not plan.
• Capital-allocation history (deteriorating). The M&A machine created value for two decades, but the auto/e-Axle build-out destroyed it — multi-hundred-billion-yen impairments and onerous contracts. ROE has collapsed from a stated ≥18% target to ~6.3%; ROIC ~3.4%. Buyback cancelled, dividend suspended — capital return frozen by the crisis.
• Red flags (severe, confirmed). This is not a "watch for" — it is realised: CFO Akinobu Samura, VP Yoshihisa Kitao, Chairman Hiroshi Kobe, and founder Nagamori all departed; an Executive Responsibility Investigation Committee is determining directors'/auditors' legal liability for FY2020–Q1 FY2025. CEO base-pay cut until the internal-management confirmation is filed (~end-Oct 2026).
• Archetype. A founder-dominant company mid-forced-transition to professional management, under a governance regime imposed from outside (TSE). For this stage that implies elevated execution risk and the possibility of a genuine culture reset — the bull and bear both live here.

Forensic Red Flags ← read this lens first

Acting as a forensic equity analyst. Nidec is a live forensic case study; the irregularities are found and admitted, not hypothesised.

Confirmed misconduct (third-party committee, final report 17 Apr 2026):

• >1,000 instances of improper accounting across multiple bases, FY2020–Q1 FY2025.
• Types: (1) avoiding inventory impairment to defer cost; (2) avoiding fixed-asset impairment; (3) capitalising labour costs as fixed assets to defer expense; (4) government grants/subsidy reserves booked as profit/revenue; (5) understated bad-debt/credit reserves; (6) misreported customs values (country-of-origin / tariff evasion — Italian plant) and a ¥200M Zhejiang subsidiary payment issue.
• Geographies/units named: Italy, Switzerland, China (Zhejiang); the automotive inverter business central.
• Every one of these flatters the exact lines an analyst trusts: inventory, PP&E, gross margin, operating profit, receivables quality. The FY2024 "record" is contaminated by construction.

Cash-flow vs earnings divergence: with grants booked as profit and costs capitalised/deferred, reported earnings overstated economic cash generation — the classic accrual-inflation pattern. Exact reconciliation is impossible pre-restatement (n/a — under restatement).

Auditor & regulator:

• PwC Japan: disclaimer of opinion on the FY2025 securities report (insufficient audit evidence). An auditor refusing to opine is the most serious possible flag short of an adverse opinion.
• TSE: "security on special alert" from 28 Oct 2025; improvement plan submitted 28 Jan 2026, revised 27 Apr 2026; internal-management confirmation due ~end-Oct 2026; delisting possible if TSE sees inadequate remediation after follow-up.
• Reported Japan securities-commission (SESC) interest.
• FY2026 annual result postponed pending restatement.

Second scandal — product quality (May 2026): >1,000 suspected cases of unapproved changes to materials (96.7%), processes and designs, in appliances + auto; "no immediate safety/functionality issue" claimed; outside-expert committee due to report ~end-Aug 2026. Surfaced by the accounting internal inspection — i.e. the controls failure is systemic, not confined to the finance function.

Regulatory findings (required sub-section):

• SEC (EDGAR EFTS — LR, AAER): none — Nidec has no CIK and is not an SEC registrant, so no SEC enforcement search is applicable. This is a coverage gap, not a clean bill.
• Non-SEC / Japan & other: the TSE special-alert designation, PwC disclaimer, reported SESC attention, and customs/tariff-evasion findings (Italy) are the material actions — all ``. An Executive Responsibility Investigation Committee is live on director/auditor liability.
• Item-3 / legal-proceedings equivalent: no 10-KForm 10-KA company’s audited annual report to the US regulator. The most complete thing it publishes. on the shelf (foreign filer); the analogous disclosure is Nidec's own internal-control-improvement statements, quoted above.
• Verdict on this lens: material adverse regulatory and forensic findings CONFIRMED — twin misconduct (accounting + quality), disclaimer of opinion, TSE special-alert/delisting track. This is the opposite of "no findings."

---

Phase D — Project & stress-test

Forward Projection

Honest position: a credible bottom-up EPS model is not possible for Nidec today, and pretending otherwise would violate provenance discipline. The base actuals (FY2024, and FY2020–Q1 FY2025) are under restatement; FY2025 guidance predates the full ¥250B impairment; FY2026 is postponed; the auditor won't opine. Any three-year EPS path built on those inputs would be stacked on corrupted — a plausible-looking fabrication of exactly the kind the SKILL forbids. So:

• FY2025 (yr-end Mar 2026): likely a loss or near-breakeven year once the ¥250B impairment and e-Axle exit costs land against a ~¥260B "clean" OP guide — i.e. the impairment can consume most-to-all of the year's operating profit. Reported EPS: n/a — under restatement / result postponed.
• FY2026–FY2027 (the Conversion 2027 window): if (big if) the books are restated cleanly, e-Axle is fully exited, and data-center power/cooling + appliances + HDD carry the group, a normalised operating margin back toward high-single/low-double digits on a ~¥2.4–2.6T sales base is the bull's arithmetic — but this is a scenario, not a forecast, and gated entirely on the audit. ``.

Base / Bull / Bear (qualitative, because the inputs aren't clean):

• Bull: clean restatement by ~end-2026; delisting avoided; e-Axle exit stops the bleeding; data-center cooling + BESS become a real 3rd growth leg; margins normalise; the stock re-rates from a governance discount toward peer multiples. Continuation of the +30% YTD move.
• Base: protracted remediation through 2026–2027; the operating turnaround is real but slow; the stock stays a headline-whipsawed, discount-rated recovery play; no delisting but no clean multiple either.
• Bear: the restatement deepens (more units, bigger numbers); the quality scandal triggers customer requalifications/lost programs; SESC action or a further disclaimer; delisting risk crystallises; equity impaired.

Brier forecast: not logged. Per --watchlist rules, skip our model create in the loop; and here the honest binary is governance, not EPS. If Connor wants one later, the scoreable question is: "Nidec (6594.T) receives an unqualified/clean audit opinion on restated FY2025 accounts AND avoids TSE delisting by 31 Dec 2027" — a p worth pricing once he forms a view. (No forecast created, per instructions.)

Bull vs Bear

Bull case. Nidec is a genuinely world-class motor franchise — #1 globally, near-monopoly in HDD spindle motors (declining but cash-rich), an oligopoly seat in precision reducers, and the largest appliance/industrial motor base on earth — now shedding its worst business (e-Axle) and re-pointing at the best secular demand (AI data-center power & cooling, BESS). The scandal, brutal as it is, is arguably cathartic: it forced out an 81-year-old founder who couldn't let go, is installing external-governance discipline, cleared a toxic profit-at-any-cost culture, and is sizing the impairment in one hit. On headline multiples (~10–14x fwd P/E, ~1.2x EV/Sales) the equity is cheap versus Regal Rexnord (~20x) and Nabtesco (~28x). The market seems to agree — +30% YTD. The contrarian bull is: this is a great asset temporarily un-ownable for governance reasons, and the un-ownability is exactly why it's cheap; when the auditor signs, the discount closes.

Bear case (2–3 permanent-impairment risks).

1. The books can't be trusted, and might get worse. A disclaimer of opinion + 1,000+ instances across six irregularity types + still-unsized restatement means the reported franchise economics may be materially worse than the "record" FY2024 implied. You are buying a black box the auditor won't sign.
2. The moat was M&A and quality-trust — both are impaired. Pausing acquisitions removes the historic value-creation engine; the quality scandal (unapproved material swaps) attacks the component-supplier's core asset — customer trust — and risks requalifications/lost programs that permanently shrink the served market.
3. Delisting / regulatory tail. TSE special-alert is a real delisting track; SESC action is possible; a second audit failure would be terminal for the equity.

Pre-mortem (18 months out, thesis broke): It's early 2028. The restatement came back bigger than ¥250B and reached into the appliance segment; PwC issued a second qualified opinion; a major appliance OEM pulled programs after the quality report; TSE extended the special-alert and the stock got hit on delisting fear. The e-Axle exit costs ran over. The "+30% YTD 2026" bounce was a bull trap — a market that priced air-clearing before the air was actually clear.

Are multiples too high? Optically no (cheap vs peers) but effectively unknowable — a low P/E on unauditable earnings isn't cheap, it's a warning. The honest statement: you cannot value Nidec on multiples until the earnings are re-audited.

Contrarian view (what the market refuses to see): The market is trading the scandal as a governance event with a clean-up date (hence the +30% bounce). What it may be under-weighting is that the accounting fraud and the quality fraud share a single root cause — a controls-and-culture failure that spanned finance AND manufacturing across multiple countries for five+ years. That is not a "one-off charge"; it is evidence the system was compromised. The bounce assumes the disease is bounded; the two-scandal pattern says it might not be.

Devil's Advocate (short-seller)

You are a skeptical short-seller dismantling the bull case.

• "Cheap" is a trap. ~10–14x fwd P/E is on numbers the auditor refused to sign and management is actively restating downward. Strip the grants-as-revenue, the deferred inventory/fixed-asset impairments, and the capitalised labour, and true normalised earnings are lower — the "cheap" multiple inflates.
• Revenue concentration shift = auto blows a hole. The e-Axle exit removes a large-revenue (if unprofitable) line; the served-market story now leans on data-center cooling, where Nidec is a challenger, not a leader — Vertiv (~11.3%) and the top-5 (~35%) own the CDU market. Betting the growth pivot on a market others dominate is not derisking; it's swapping a red ocean (EV) for a contested one (cooling).
• The moat is weaker than bulls think because two of its pillars — the M&A machine and manufacturing-trust — are impaired by management's own actions (M&A suspended; quality misconduct admitted).
• Most dangerous competitor bulls underestimate: in the growth pillar, Vertiv/Schneider (thermal scale + hyperscaler relationships) can out-execute a scandal-distracted challenger; in reducers, Harmonic Drive Systems/Nabtesco are cleaner, focused pure-plays for the robotics narrative.
• Worst capital-allocation / governance: the entire scandal — grants booked as profit, customs mislabelling, a founder who created a "losses are unacceptable" culture and wouldn't cede control, a decade of failed succession, a cancelled buyback and suspended dividend.
• Assumptions that must hold for today's price: (a) restatement is bounded at ~¥250B and doesn't spread; (b) no delisting; (c) PwC signs restated books; (d) quality scandal costs are containable with no major program losses; (e) data-center cooling scales into a real margin engine. Break any one and the recovery thesis fails.
• If growth disappoints 20–30% and a further impairment lands, the equity could be down materially from here — and the option value is asymmetric to the downside because of the delisting tail.
• Single scenario that permanently impairs: delisting from the TSE, or a second disclaimer/qualified opinion that severs institutional ownership. Plausibility: non-trivial while on special alert — this is the line that keeps Nidec off the buy list.

Management Questions (ordered by information value)

1. Will PwC Japan issue an unqualified opinion on the restated FY2025 accounts, and on what date do you expect the FY2026 result to be published?
2. Is the ¥250B impairment the ceiling, or can the restatement extend to segments (appliance, machinery) or years beyond FY2020–Q1 FY2025?
3. What is your base-case probability and timeline for exiting TSE special-alert status without delisting, and what specifically must the internal-management confirmation (due ~Oct 2026) demonstrate?
4. The accounting and quality failures span finance and manufacturing across Italy, Switzerland and China. What convinces you this is a bounded controls failure and not a systemic culture problem that could surface elsewhere?
5. What are the total cash and P&L costs of the e-Axle withdrawal (contract break fees, impairments, restructuring, supplier claims), and when is the auto segment cash-flow neutral?
6. With M&A suspended, what is the organic growth engine — and how large/what-margin can data-center power & cooling realistically become by FY2027 given Vertiv/Schneider incumbency?
7. On the quality scandal: how many customer programs are at risk of requalification or loss, and what is the worst-case revenue exposure?
8. What is the new capital-return policy — when do dividend and buyback resume, and under what leverage/coverage conditions?
9. How do you restructure incentives so that "hit the number at any cost" cannot recur — specifically, how is executive comp now tied to audited (not reported) results?
10. What is Nidec's rare-earth-magnet exposure and mitigation (recycling, non-rare-earth motor designs, supply diversification) given Chinese export controls?
11. What is the structural decline curve for HDD spindle motors, and how much cash does that cash cow still throw off through FY2028?
12. Which executives/directors will bear legal or financial liability from the Executive Responsibility Investigation, and will there be clawbacks?
13. Post-Nagamori, describe the board's independence and the new decision-rights — who can now veto an aggressive target or an acquisition?
14. In precision reducers (Nidec Drive Technology), what is your realistic humanoid-robot content-per-unit and share versus Harmonic Drive Systems/Nabtesco over the next 3–5 years?
15. What single leading indicator should investors watch to know the turnaround is working before the audited numbers arrive?
