Nachi-Fujikoshi

Phase A — Understand the business

Lens 1 · Company Overview

Nachi-Fujikoshi ("NACHI") was founded in December 1928 in Toyama by Kohki Imura, on the credo that domestic machine-tool capability is the foundation of an industrial nation. A decade in, it added a steel mill to build a fully integrated materials → tools → machines chain — the structural DNA that still defines it. The "NACHI" brand dates to a 1929 Imperial inspection of a Fujikoshi hacksaw blade.

Today it is a ~¥236B-revenue ($1.6B) diversified industrial organized into three reporting segments that management brands as "a comprehensive machinery manufacturer with its robotics business at its core" — a positioning statement the numbers do not support (robots are the smallest of its major product lines).

Three reporting segments (FY2025 net sales, ¥M):

• Machinery & Tools — 73,407 (31%): Cutting Tools 34,158 · Machine Tools 13,998 · Robots 25,250
• Components (Parts) — 147,255 (62%): Bearings 85,419 · Hydraulic Equipment 39,742 · Automotive Hydraulics 22,093
• Other — 15,240 (6%): Special Steel 13,143 · Others 2,097

Business model. A classic Japanese monozukuri parts-and-capital-goods maker: it sells (a) consumable/OEM components — bearings, hydraulic valves/pumps/motors, cutting tools — into automotive, construction machinery, machine tools and industrial equipment (recurring, replacement-driven, price-competitive); and (b) capital equipment — industrial robots, machine tools — which is cyclical, project-based, and tied to customers' capex cycles. Contracts are conventional OEM supply and equipment sales; no take-or-pay, no meaningful recurring-software layer disclosed. There is real vertical integration: its own special steel (high-speed tool steel) feeds its cutting tools and bearings — a cost/quality moat in the components business, not the robot business.

Customers / suppliers / competitors.

• Customers: automotive OEMs and tier-1s (the dominant end-market across bearings, hydraulics, robots, tools), construction-machinery makers, machine-tool builders, electronics/semiconductor equipment. Toyota is both a top customer AND a 5.29% shareholder — the single most important relationship in the file.
• Suppliers: steel/alloy inputs (partly self-supplied), and — critically — precision reducers (RV / strain-wave gears) for its robots, which it buys from Nabtesco and Harmonic Drive rather than making (see Lens 2/3).
• Competitors: in robots — Fanuc, Yaskawa, ABB, KUKA, Kawasaki, Mitsubishi Electric, Denso above it and Estun/Efort/Inovance/Siasun (China) below it; in bearings — NSK, NTN, JTEKT (Koyo), SKF, Schaeffler, Timken, THK; in cutting tools — Sandvik, Mitsubishi Materials, OSG, Kyocera.

Chokepoints & single-source dependencies:

1. Reducers are the binding constraint on the robot business. Nachi does not own the RV/strain-wave reducer — the highest-value, highest-margin part of an industrial robot. It buys from Nabtesco and Harmonic Drive, the very suppliers who sell to every Big-Four competitor too. Nachi is therefore a price-taker on its own most-critical input and has no cost moat versus Fanuc/Yaskawa in arms. This is the structural reason its robot segment is sub-scale and low-margin.
2. Special-steel self-supply is a genuine advantage in components — vertical integration into high-speed tool steel differentiates its cutting tools and bearing steels on cost and quality. The moat runs the opposite direction from the robot story.
3. End-market concentration in automotive across nearly every product line — one cyclical exposure amplified through bearings, hydraulics, robots and tools simultaneously. An auto-capex downturn hits all four at once (as FY2025 showed).
4. China as both a demand market (15%) and a competitive threat — Nachi famously sold robot know-how/technical documents to China and Korea pre-2010, seeding the very domestic champions (Estun/Efort) now undercutting it 20–30%.

Lens 3 · Competitive Advantages (moats)

Where the moat is real (Components):

• Vertical integration into special steel — self-supplied tool steel gives durable cost/quality edge in cutting tools and bearing steels. Hard to replicate; ~a-century of metallurgy know-how.
• Bearings scale + OEM lock-in — bearings (¥85B) is a top-tier Japanese franchise alongside NSK/NTN/JTEKT; designed-in to auto/construction platforms with high switching costs and multi-year qualification cycles. This is the crown jewel.
• Toyota relationship — customer + 5.29% owner; a stabilizer and a distribution moat in Japanese auto.
• Hydraulics — strong niche in construction-machinery and machine-tool hydraulics; steady, if cyclical.

Where the "moat" is thin or absent (Robots):

• ~3% global robot market share — sub-scale versus Fanuc/Yaskawa/ABB/KUKA, who each dwarf it on installed base, service network and R&D.
• No reducer ownership (Lens 2) — the part that confers pricing power in robotics is bought in. Nachi competes on application niches (heavy spot-welding SRA, compact MZ, CZ cobots) and Japanese-domestic service, not on a technology moat.
• Squeezed from below by Chinese arms at 20–30% lower price — a structural margin vice with no obvious escape.

Bargaining power. Weak-to-neutral. Over reducer suppliers (Nabtesco/Harmonic): weak — commoditized buyer. Over auto OEM customers: weak (Toyota et al. dictate terms; auto purchasing is brutal). The one place it has power is where its steel integration + bearings qualification create switching costs. Net: this is a good components company and a below-average robot company wearing a robot company's brand. The 0.5× book multiple (Lens 7) is the market pricing exactly that gap.

Lens 4 · Segments

FY2025 vs FY2024 (net sales / operating profit, ¥M) — all ``:

Geography (FY2025 sales, ¥M): Japan 115,965 (49.2%) · Overseas 119,938 (50.8%) — of which China 35,713 (15.1%, −3.9% YoY) · Americas 34,912 (14.8%, −3.1%) · ASEAN+other 31,721 (13.4%) · Europe 11,102 (4.7%) · India 6,489 (2.8%, +12.6%).

Reading the trend.

• Robots collapsed −18.3% — the headline story. Global auto/electronics capex pause + Chinese price war. The segment management calls its "core" is the one that shrank hardest.
• Components is the ballast — flat sales (+0.6%) but the segment carried the group; the operating-profit swing came here (Components OP 1,664 → 4,998, +200%) on cost reduction and price hikes, not volume.
• Machinery & Tools OP actually rose (3,879 → 4,279, +10.3%) despite the robot revenue drop — cutting tools and machine tools offset it.
• India is the only growth geography (+12.6%); China is now a drag.
• FY2026 guidance leans on a robot rebound (Robots guided +24% to 31,400) — the swing factor for the year (see Lens 5/11). Whether that materializes against China is the whole bull/bear.

Phase B — Measure performance

Lens 5 · Earnings Result

FY2025 full-year (ended 30-Nov-2025), consolidated, ¥M:

The tape's key tension: revenue fell, profit surged. This is a margin-and-cost story, not a growth story. The OP bridge FY2024→FY2025 (+¥3,137M) breaks down as: price increases +23 · cost reduction +13 · lower fixed costs/SG&A +32 (total +68), partly offset by material prices −11 · FX −6 · lower operating rate −20 (total −37). Translation: management cut its way to higher profit while volumes softened — classic late-cycle Japanese self-help.

Which lines drove it: Components OP +¥3.3B (+200%) did the heavy lifting; Machinery & Tools +¥0.4B; Other −¥0.6B. Robots were a volume drag, not a profit driver.

Balance-sheet flags (FY2025): Total assets ¥331,295M · Stockholders' equity ¥170,597M · equity ratio 51.5% (healthy) · interest-bearing debt ¥83,214M · Net D/E 0.32 (conservative) · ROE just 3.2% (the core problem — see Lens 7). Facility investment ¥9,911M vs D&A ¥18,707M — capex running at ~half depreciation, i.e. the company is not reinvesting heavily; it is harvesting. Employees 6,532 (down from 6,826) — headcount cut.

Quality-of-earnings flag (important). FY2025 net profit was flattered by one-off gains from selling policy-holding cross-shareholdings (~¥1.9B of investment-securities sale gains), which offset ~¥1.2B of structural-reform charges (≈¥0.6B overseas-plant impairment + ¥0.4B special severance). So the +56.7% net-income jump is partly non-operating and non-recurring; the cleaner read is the operating recovery (+47%) and the cost-out. This shows up in FY2026 Q1: operating profit +26.9% but net profit −21.7% — because the prior-year quarter had the securities gain that this year's didn't.

FY2026 Q1 (Dec-2025–Feb-2026): Net sales ¥60.2B (+6.2%) · OP ¥2.7B (+26.9%) · Ordinary ¥2.1B (+45.8%) · Net ¥1.1B (−21.7%, one-off comp effect).

Market reaction / what's priced. The stock ran from a ¥2,640 low (Apr-2025) to ¥6,150 (Jul-2026) — roughly a double — as the operating recovery, the cross-shareholding unwind and the TSE capital-efficiency push re-rated a sub-book stock. The market has already paid for the turn; the question (Lens 12/13) is whether the robot rebound and ROE improvement in guidance are real.

Lens 6 · Earnings Calls (sentiment trend)

No transcripts on the research shelf and NACHI does not publish English earnings-call transcripts; management commentary is reconstructed from IR documents and Nikkei coverage.

What management keeps saying (FY2024→FY2025 arc):

• "Structural reform" is the dominant theme — overseas plant consolidation, headcount reduction, fixed-cost cuts. The tone across FY2025 was defensive/restructuring, not expansionary. Management is managing a downcycle, not riding a boom.
• "Robotics at the core" branding persists even as the segment shrank — a stated aspiration (2018 policy: "Innovate in manufacturing worldwide with advanced FA systems and mechatronics") increasingly at odds with the P&L. Watch for whether the FY2026 robot-rebound guidance is delivered or quietly walked back.
• Capital-efficiency / shareholder-return language is new and rising — selling policy shareholdings, holding the ¥100 dividend, and (implicitly) responding to the TSE "PBR<1" reform. This is the genuinely new, share-price-relevant shift in tone.

What they stopped emphasizing: aggressive robot-volume/market-share growth talk — replaced by margin, cost and mix discipline. Sentiment trajectory: from cyclical-growth optimism (2022-23) → restructuring realism (2024-25) → cautious cyclical-recovery + self-help (FY2026 guidance). Falsifiable tell to track: does the FY2026 robot-revenue guide (+24%) survive the next two quarterly prints?

Lens 7 · Comps

Peer set = the Japanese robotics/reducer/bearings complex. Multiples are `` with source/date; where not sourced, n/a (never fabricated).

Sources:;;;;;.

Reading the comps.

• Nachi is by far the cheapest on book (PBR ~0.5× vs peers well above 1×) — the market values it at half its net assets, the signature of a low-ROE (3.2%) Japanese industrial with a structurally challenged growth segment. The trailing P/E (29×) is optically high only because earnings are depressed; on normalized/forward earnings (20.8×) it is cheaper than every listed peer.
• The "arms dealers" (Nabtesco, Harmonic) and the Big Four (Fanuc, Yaskawa) command premium multiples precisely because they own the technology chokepoint or the scale Nachi lacks. Nachi trades where it does because of the Lens 2/3 structural gaps — the discount is earned, not an anomaly.
• The bull case is a re-rating of the discount, not multiple-expansion to peer level — a bearings/components value stock at 0.5× book with a self-help + TSE-reform catalyst, not a robotics growth re-rate. Comparing it to Fanuc is a category error.

Lens 8 · Stock-Price Catalysts

Move-drivers over the last ~5 years (mostly ``):

• Apr-2025 low ¥2,640 → Jul-2026 ¥6,150 (~+130%): the dominant move. Drivers: (1) operating recovery (OP +47% FY2025) off a depressed FY2024 base; (2) cross-shareholding sell-down crystallizing value and signaling capital-efficiency reform; (3) TSE "PBR below 1×" pressure on management to improve returns — a market-wide re-rating of cheap Japanese industrials that Nachi rode; (4) broader Japan-value / weak-yen (¥149–150/$) export-earnings tailwind.
• 2022–2024 de-rate: OP fell from ¥17.0B (FY2022) to ¥6.6B (FY2024) as the post-COVID capex boom faded, auto/electronics investment paused, and China turned from growth market to price-war battleground — the stock and earnings both compressed (sales peaked ¥265.5B FY2023).
• Quarterly prints move it, but the reaction is earnings-quality-sensitive: FY2026 Q1 showed +27% OP yet −22% net (one-off comp), a setup that can whipsaw a headline-reading tape.

What the pattern reveals: the market reacts to (a) the operating/margin cycle (cost-out + price + auto capex), (b) capital-return / governance signals (buyback, dividend, cross-shareholding unwind, PBR reform), and (c) the yen. It reacts far less to "robotics/humanoid" narrative than a casual observer would expect — because robots are 11% of sales and shrinking. This is a cyclical-value stock that trades on margins, capital allocation and FX — not a thematic robotics stock.

Phase C — Judge people & books

Lens 9 · Management

CEO / Chairman: Hiroo Honma (Representative Director; listed variously as President and Chairman). Deep NACHI-lifer profile typical of Japanese industrials; granular English biography and precise tenure are thin in public sources — flag as an information gap.

1. Track record. The verifiable recent record is a restructuring/margin turnaround: OP +47% (FY2025), Components OP tripled, fixed costs and headcount cut (6,826→6,532), overseas plants consolidated. Competently managed a downcycle. What is NOT in the record: growing the robot business — it shrank 18% on their watch, and the "robotics at the core" strategy has not translated into share gains against Fanuc/Yaskawa or the Chinese.
2. Tenure & skin in the game. Long-tenured insiders (Japanese norm). Insider ownership is low (again the Japanese norm); the anchoring large holder is Toyota at 5.29% — customer-shareholder alignment rather than management equity alignment. No insider-transactions.csv on the shelf — treat insider-ownership specifics as n/a.
3. Capital allocation. This is where the story is turning. Historically a reinvest-and-harvest industrial (capex now ~½ of D&A — deliberately under-reinvesting the mature businesses). Recently selling policy cross-shareholdings and holding the dividend — a governance-improvement, capital-efficiency posture consistent with TSE pressure. But ROE is only 3.2% and the equity ratio (51.5%) with net D/E 0.32 leaves an over-capitalized balance sheet — the classic Japanese setup where a buyback/return program is the obvious next value lever and its presence/absence is the swing factor.
4. Red flags. (a) Historical bearings price-fixing cartel participation (JFTC/EU/US/China — Lens 10) — a governance/culture stain, though a decade old and largely resolved. (b) Persistent gap between the "robotics core" narrative and the P&L — mild promotional/aspirational framing. (c) Low insider equity / cross-shareholding legacy — being unwound. No evidence of self-dealing or aggressive accounting beyond the (disclosed, normal) one-off securities gains.
5. Archetype. Professional-manager / salaryman stewards of a century-old conglomerate, not founder-owners. Implication: expect steady, incremental, consensus-driven capital discipline and restructuring — and expect them to be slow to exit or radically restructure the sub-scale robot business even when the numbers argue for it. The value case rests on the TSE/governance ratchet forcing returns up, not on visionary reinvention.

Lens 10 · Forensic Red Flags

Accounting-risk scan (web-only; no filings on shelf — all /):

• Earnings quality: FY2025 net income inflated by ~¥1.9B non-recurring securities-sale gains, offsetting ~¥1.2B restructuring charges — so headline net (+56.7%) overstates the underlying run-rate; operating profit (+47%) is the cleaner number. The FY2026 Q1 net −21.7% (vs OP +27%) confirms the prior-year one-off. Watch for continued reliance on cross-shareholding disposals to pad net income.
• Capex vs D&A: facility investment ¥9,911M vs D&A ¥18,707M — capex ~53% of depreciation. Flatters near-term free cash flow but signals under-investment in mature assets; not fraud, but a quality-of-FCF caveat and a longevity question for the robot/machine-tool lines.
• Segment reporting: clean and detailed (product-level sales + segment OP disclosed). No obvious segment-masking. Robot losses/thin margins are not separately disclosed at the product level (only the Machinery & Tools segment OP is given) — the ¥25.3B robot line's true profitability is opaque and plausibly break-even-to-loss given the price war; treat robot-segment profitability as n/a — not disclosed.
• Balance sheet: conservative (equity ratio 51.5%, net D/E 0.32). Inventory/receivables did not visibly outrun (declining) sales. No goodwill-heavy acquisition risk evident. Over-capitalization is the "flag" — in the Japanese value sense (idle capital), not a solvency risk.
• SBC: immaterial (Japanese industrial; not a stock-comp-flattered non-GAAP story).

Regulatory findings (required sub-section — read from regulatory/regulatory-findings.md + web):

• SEC (EDGAR EFTS — LR + AAER): 0 findings. Nachi has no CIK and is not an SEC registrant, so no EDGAR enforcement search is possible.
• Bearings price-fixing cartel — MATERIAL, multi-jurisdiction (historical):
• Japan (JFTC), 2012: criminal charges for price-fixing on industrial/automotive bearings; NACHI among the manufacturers penalized.
• EU Commission, 19-Mar-2014 (Case COMP/39922 – Bearings, Art. 101 TFEU): decision addressed to Nachi-Fujikoshi Corporation and Nachi Europe GmbH.
• China (NDRC), 2014: part of the record ¥1.24B-yuan Japanese auto-parts/bearings fine wave; Nachi was exempted as a leniency/first-reporter applicant (cooperated, provided proof).
• US: named in the In re Automotive Parts / Bearings antitrust class actions; settlements covered direct purchases of bearings 2000–2014.
• Assessment: a genuine governance/culture red flag, but decade-old, disclosed, and substantially resolved (fines paid, settlements closed); Nachi's leniency posture in China mitigates. Not an ongoing solvency or going-concern issue — a character-of-the-franchise data point that supports the "old-economy, price-competitive commodity components" read.
• Non-SEC current enforcement (FTC/DOJ/recall) web scan: no material recent (post-2015) enforcement or product-recall hits surfaced.
• 10-K Item 3: n/a — no US filing exists.

Net Lens-10 verdict: No modern fraud/going-concern signal. Two real caveats: (1) one-off-gain reliance flattering net income, and (2) a historical cartel record consistent with a mature, commoditized bearings franchise. Robot-segment profitability is undisclosed and probably weak.

Phase D — Project & stress-test

Lens 11 · Forward Projection

Anchor: FY2025 actuals + management FY2026 guidance (their own numbers):

• FY2026 guide: Net sales ¥243,000M (+3.0%) · OP ¥12,100M (+23.8%, margin 5.0%) · Net profit ¥6,400M · EPS ~¥294 · dividend ¥100.
• The guide leans hard on a robot rebound (Robots guided +24% to ¥31,400M) and continued Components strength (OP ¥5,770M) — plus a big step-up in facility investment to ¥22,000M (from ¥9,911M), i.e. management is finally reinvesting.

Three-year EPS path (FY2026–FY2028), ¥/share — all ``, arithmetic shown, base anchored to guidance:

The number that actually decides the stock is ROE, not EPS. At ~0.5× book, a re-rate to ~0.7–0.8× book requires ROE moving from 3.2% toward ~6%+ — achievable via (a) margin recovery (in train) and (b) balance-sheet return (buyback of the over-capitalized equity). The EPS path matters less than whether management deploys the idle capital.

(Per --watchlist rules: no forecast.ts create logged in this unattended sweep.)

Lens 12 · Bull vs Bear

Bull case. A 0.5×-book, net-cash-ish (net D/E 0.32) Japanese industrial with a genuine, defensible components franchise (bearings + hydraulics + special-steel integration, 62% of sales) that just proved it can expand margins in a down-volume year (Components OP +200%, group OP +47%). Layer on the TSE capital-efficiency reform ratchet: management is already selling cross-shareholdings and can return the over-capitalized balance sheet, dragging ROE (3.2%) up and the PBR discount closed. Optional upside: an actual robot-cycle rebound (auto capex normalizes, humanoid/automation secular demand lifts the whole reducer/robot complex) turns the worst segment from drag to tailwind. It's a self-help + cheap-cyclical value story with a free call option on robotics. Target framing: re-rate to ~0.7–0.8× book on ~¥170B+ equity ≈ ¥5,400–6,300/share of asset value alone; ~15–18× a normalized ~¥350 EPS ≈ ¥5,300–6,300 — i.e. fair-ish around today's ¥6,150, cheap on any ROE improvement.

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

1. The robot business is structurally, not cyclically, impaired — no reducer moat, sub-scale vs the Big Four, undercut 20–30% by Chinese champions it helped create. If robots keep shrinking, the "robotics core" thesis is dead and the segment is a perennial value-drag that management is culturally too slow to exit.
2. Bearings/hydraulics are commodity-cyclical and China-exposed — the profit engine is late-cycle auto/construction components in a market where Chinese domestic supply is climbing the value chain (same story as robots, one product tier behind). Margin recovery could prove a cost-out ceiling, not a growth floor.
3. Earnings quality / capital-return execution risk — strip the one-off securities gains and net income is thinner; if the TSE-reform capital return doesn't come (salaryman inertia), the stock stays a 0.5×-book value trap indefinitely, as many Japanese industrials have for decades.

Pre-mortem (18 months out, thesis broke — what happened?). Auto OEMs cut capex into a 2026–27 EV-transition air-pocket; robot revenue misses the +24% guide badly and Components margins give back the cost-out gains; China both shrinks as a market and floods bearings; management holds the dividend but announces no buyback, so ROE stays ~3% and the PBR discount widens back toward 0.4×. The stock round-trips to the ¥3,000s. The "humanoid reducer" bulls learn Nachi doesn't own the reducer.

Are multiples too high? No — 0.5× book / 20.8× forward is cheap; the risk is a value trap (cheap forever), not overvaluation. The one place it's "expensive" is the optical trailing 29× P/E on depressed earnings.

Contrarian view (what the market refuses to see). Two-sided. Bulls refuse to see that this is not a robotics stock — it's a cheap bearings company with a bad robot arm, and the reducer bottleneck means the humanoid/automation boom accrues to Nabtesco/Harmonic, not Nachi. Bears refuse to see that being a 0.5×-book, over-capitalized, cash-generative components maker in the middle of Japan's forced governance re-rating is exactly the setup that mechanically re-rates — the value unlock doesn't need the robot business to work at all.

Lens 13 · Devil's Advocate (short-seller)

Dismantling the bull case:

• What structurally breaks the money-making? The components profit engine is commodity bearings/hydraulics into a single cyclical end-market (auto) increasingly contested by Chinese domestic suppliers. The FY2025 profit jump was cost-cutting + price + one-off gains against falling volume — you cannot cost-cut to growth forever, and the operating-rate drag (−¥20 in the OP bridge) shows volume is the enemy.
• Where is revenue concentrated / what if it shifts? Automotive across all four product lines + China 15% and falling. An EV-transition capex pause or Chinese import-substitution in bearings hits everything at once. India (+12.6%) is too small to offset.
• Why is the moat weaker than bulls think? In robots there is no moat (bought-in reducers, 3% share, price war). In bearings the moat is relative — real vs new entrants, thin vs NSK/NTN/Schaeffler who out-scale it. Special-steel integration is nice but it's a cost edge on commodities, not pricing power.
• Most dangerous competitor bulls underestimate: Chinese domestic makers moving up-market — Estun/Inovance in robots today, Chinese bearing makers tomorrow — plus the fact that Nabtesco/Harmonic capture the robotics value Nachi's story implies it should.
• Worst capital-allocation history: decades of under-earning (3.2% ROE) on an over-capitalized balance sheet and legacy cross-shareholdings — value trapped for years. And the cartel record (JFTC/EU/US) says the culture historically competed on collusion, not innovation.
• What must hold for today's ¥6,150? That the FY2026 guide (OP +24%, robots +24%) is delivered, that margin gains stick, and — the load-bearing assumption — that management actually returns the excess capital to lift ROE. Miss any and it's a value trap.
• If growth disappoints 20–30%: robots back to ~¥20B, Components flat-to-down, OP margin to ~3.5% → net toward ¥3.5–4B, EPS ~¥170, and at 0.4–0.5× book the stock revisits the ¥3,000s (−45–50%).
• Single permanent-impairment scenario, plausibility: Chinese import-substitution + Big-Four scale permanently compress both robots and bearings margins while management fails to restructure the robot business or return capital → a shrinking, low-return conglomerate stuck at 0.4× book. Plausibility: moderate — the components franchise and Toyota anchor make outright impairment less likely than a long, dull value-trap grind, which is the base short thesis.

Lens 14 · Management Questions (ordered by information value)

1. Is the robot segment profitable at the operating line, and if not, what is the concrete plan and deadline to fix or exit it? (The undisclosed number that most changes the thesis.)
2. Will you commit to a share buyback to bring the equity ratio (51.5%) and net D/E (0.32) to a target that lifts ROE toward a stated goal — and what is that ROE target and date?
3. FY2026 guides robots +24% after a −18% year — what specifically underwrites that (orders, customer, geography), and what is your visibility today?
4. On reducers (RV/strain-wave): you buy from Nabtesco/Harmonic who supply your competitors — do you have any plan to insource, co-develop, or otherwise close the cost gap that caps robot margins?
5. How do you defend bearings and hydraulics margins against Chinese domestic suppliers moving up the value chain, given China is now a declining 15% of sales?
6. Capex is guided to more than double (¥9.9B→¥22B) — where is it going, and what return threshold must it clear? Is this maintenance catch-up or growth?
7. How much of FY2025 net income was non-recurring (securities-sale gains net of restructuring), and how many cross-shareholdings remain to be sold — i.e. how long can this cushion last?
8. What is the normalized through-cycle operating margin you believe each of the three segments can sustain, and what gets Components above its current ~3.4%?
9. Given "robotics at the core," why does the capital and the profit sit in Components — is the branding a strategy or an aspiration, and would you consider reorganizing/reporting around where value actually is?
10. What is the Toyota relationship worth commercially (as customer), and does the 5.29% stake constrain strategic options (M&A, restructuring, capital return)?
11. Where do you see humanoid/embodied-AI robotics demand, and can NACHI participate given you don't own the reducer — or is the opportunity actually in your steel/bearings/components feeding others' humanoids?
12. What are the structural-reform end-state targets (plants, headcount, fixed cost) and how much benefit is still to come vs. already booked?
13. How exposed is the FY2026 plan to FX (guided ¥145/$ vs ¥149 realized) and to a further auto-capex downturn — what's the downside sensitivity?
14. What is your M&A posture — bolt-on to scale bearings/tools, or divest the sub-scale robot business — and would you sell a business that dilutes group ROE?
15. Longer term, what does NACHI look like in five years — a focused components leader, or a diversified machinery conglomerate — and how are incentives aligned to that outcome?
