愛知製鋼株式会社（Aichi Steel Corporation）

研究原文：Aichi Steel is the Toyota Group's only steel materials maker: the steelmaking division inside Toyoda Automatic Loom Works (1934) was spun off as Toyoda Steel in 1940 and renamed Aichi Steel in 1945. It is listed on TSE Prime and Nagoya (5482), headquartered in Tokai City, with JPY 25,016m of capital, 4,427 consolidated employees, 64,520,820 post-split shares issued of which 263,301 are treasury shares. Stated business: steel, forgings, and electronic functional materials/components/magnet applications. The investable entity is a group-captive materials maker, not an independent merchant steelmaker.

内部研究类型：EconomicIdentity

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Valuation and governance analysis must begin from captive-supplier status inside the Toyota system; demand, register and governance all run through that fact.

不确定性（原始记录）：Post-privatisation register and group perimeter changes are still moving (see register-motion node); minority/JV attribution of economics is only partly disclosed.

研究原文：Revenue is earned by converting purchased scrap, billets and ferroalloys into special-steel bars (HAGANE), stainless shapes, forged/machined automotive components (KITAERU) and smart electronic components (MI sensors, bonded magnets, dental magnetic attachments, metal fibres, iron supplements), sold mainly into the Toyota production system. An internal flow of JPY 21,702m in H1 FY3/27 moved steel-segment output into forging, so margin per tonne rises downstream and group profit is made where material production, forging and machining are integrated. H1 FY3/27 external revenue mix: steel 34.0%, forgings 44.4%, stainless 12.8%, smart electronics 8.0%, other 0.8%.

内部研究类型：BusinessModelMechanism

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Shareholders are exposed mainly to forging economics with a geared steel-spread overlay rather than to steel tonnage alone.

不确定性（原始记录）：Transfer pricing between steel and forging steps and the profitability of the six smart-segment sub-businesses are undisclosed; segment profit is the company's own pre-adjustment presentation.

研究原文：The profit pool sits downstream. In H1 FY3/27 forgings earned JPY 4,417m of segment profit on JPY 72,217m of external revenue (about 44% of revenue, roughly 60% of segment profit; profit +35% from JPY 3,267m), while steel segment profit fell about 71% to JPY 1,099m from JPY 3,832m as the scrap spread reversed. Stainless earned JPY 456m (from 416m), smart electronics JPY 1,120m (from 984m), other JPY 330m, with -JPY 88m of adjustments reconciling to operating profit of JPY 7,336m. The spread pain lands in steel; the resilience sits in forgings.

内部研究类型：ProfitPoolFinding

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Group profit quality depends more on forging mix and volume than on steel tonnage; cycle risk is localised in steel rather than eliminated.

不确定性（原始记录）：Segment profit is company-defined and transfer pricing is undisclosed, so the steel/forging split partly reflects internal pricing.

研究原文：The stated moat is integration: because the group develops steel, forges and machines it in one chain, material properties can be designed for the finished component (including non-heat-treated steels and e-Axle parts), which pure forgers buying merchant bar cannot replicate without a captive steel source. Stainless small-lot breadth adds a service moat. The empirical evidence is indirect: forging profit grew 35% in a half when steel profit fell 71%.

内部研究类型：MoatMechanism

内部来源标记：COVERAGE35

普通股东含义（原始记录）：The moat protects the forging margin, not the steel spread; it localises cycle risk and supports through-cycle returns.

不确定性（原始记录）：Capability-based evidence only; no measured switching-cost study, qualification specifics or contract durations are disclosed. Forging margins through the next downturn are the real test.

研究原文：Japan's leading maker of stainless steel shapes competes on variety and responsiveness rather than tonnage, with more than 4,000 shape-and-grade combinations in small lots. Its H1 FY3/27 profit rose to JPY 456m from JPY 416m even as commodity steel margins collapsed, though it is only about 12.8% of external revenue.

内部研究类型：NicheStructuralAsset

内部来源标记：COVERAGE35

普通股东含义（原始记录）：A meaningful minority of the portfolio earns niche economics, tempering through-cycle margin volatility.

不确定性（原始记录）：Leadership is the company's self-description; verified market shares are not available. Stainless furnace renewal return is unresolved.

研究原文：Earnings are an integration machine geared to the scrap-to-selling-price spread. Volume growth is real and repeatable (+28kt in FY3/26, +5.2% in H1 FY3/27, 1,030kt planned for FY3/27 versus 980kt achieved), but inputs are market-priced commodities while outputs are negotiated periodically, so the input side reprices first. The same tonne can swing from record profit to a 71% steel-segment profit decline within a year; margin is a timing artefact around a mid-single-digit structural level, and earnings quality is set more by spread management than by demand.

内部研究类型：CoreEarningsMechanism

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Reported profit will keep oscillating around normalised earning power by several billion yen per half; valuation must use through-cycle earnings.

不确定性（原始记录）：Contract terms, scrap inventory policy, hedging and the agreed H2 price-revision schedule are undisclosed; no external scrap series was used.

研究原文：FY3/26 was a record year: revenue JPY 304,341m (+1.7%, fifth consecutive record), operating profit JPY 17,371m (+44.6%), pre-tax JPY 18,485m, attributable profit JPY 11,248m (EPS JPY 170.63), driven by +28kt of volume, falling iron scrap prices, plant cost reductions and stronger subsidiaries. Against plan final-year targets, revenue reached 89.5% of JPY 340,000m while operating profit reached 115.3% of JPY 15,000m; ROE of 4.8% cleared the at-least-4% target. Operating cash flow was JPY 65,028m against capex of JPY 16,928m. The year enjoyed a favourable spread.

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Shows what the model earns when spread, volume and cost all help; it is a favourable-spread data point, not a normalised base.

不确定性（原始记录）：The part of the profit step attributable to scrap prices versus structural cost work is not separately quantified.

研究原文：H1 FY3/27 shows the same machine against a reversed spread: revenue +8.5% to JPY 162,572m, operating profit -16.5% to JPY 7,336m (margin 4.5% versus 5.7% in FY3/26), pre-tax JPY 8,071m (-13.3%), attributable profit JPY 5,299m (-5.5%), EPS JPY 82.78, comprehensive income -39.7% to JPY 7,229m. Operating-profit bridge (JPY 100m units): volume +19, selling prices +32 (incl. FX +3), plant cost reductions +8, inventory and other +24, subsidiaries +9 (about +JPY 9.2bn) against purchased inputs of about -JPY 10.6bn (raw materials -100: iron scrap -54, purchased billets -14, ferroalloys and others -32; energy -6), netting from JPY 8,784m. Parent volume 506kt (+5.2%). Quarterly profit in Q2 fell to about JPY 2,971m.

内部研究类型：PeriodResult

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Demonstrates that growth in units does not convert into profit when input inflation outruns price revisions (about JPY 3.2bn added by price revisions).

不确定性（原始记录）：Price-versus-mix split inside the selling-price line is not disclosed beyond the currency component.

研究原文：If iron scrap and energy prices keep rising faster than selling-price revisions - the pattern already visible in Q2 FY3/27 - even the cut JPY 15,000m full-year operating-profit guidance could prove optimistic, because the H1 bridge shows input prices can move profit by more than JPY 10bn in a half.

内部研究类型：RiskMechanism

内部来源标记：OPEN_DISCOVERY

普通股东含义（原始记录）：A second guidance cut would confirm that pass-through lag is structural and would delay the profit leg of the ROE bridge.

不确定性（原始记录）：Current scrap level and embedded price assumptions in guidance are not public.

研究原文：Currency moves pass through both sides of the spread: in H1 FY3/27 exchange rates added +3 (JPY 100m units) via selling prices and subtracted -15 via purchased inputs, a net negative. Macro shocks arrive filtered through Toyota-group production schedules and the scrap/alloy import basket rather than as a separate cycle.

内部研究类型：MacroTransmission

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Macro risk is second-order relative to spread management; it amplifies or relieves the main cycle.

不确定性（原始记录）：No FX hedging disclosure or scenario quantification; tariff exposure by destination undisclosed.

研究原文：On 29 October 2026 FY3/27 guidance was revised in opposite directions: revenue up to a record JPY 330,000m (+8.4%) on volume and price; operating profit down to JPY 15,000m (-13.7%), pre-tax JPY 16,000m and net profit JPY 10,000m (EPS JPY 156.18), because raw-material and energy inflation is expected to intensify in H2. H1 landed above the initial half-year plan (revenue JPY 151,900m, operating profit JPY 6,000m). Capex was trimmed from JPY 20,000m to JPY 19,000m with depreciation guided at JPY 18,000m.

内部研究类型：GuidanceRevision

内部来源标记：OPEN_DISCOVERY

普通股东含义（原始记录）：Official expectation is now volume-led growth with an H2 margin squeeze; the year-end print tests whether that framing is sufficiently conservative.

不确定性（原始记录）：The scrap and input assumptions behind guidance and the coverage by agreed price revisions are undisclosed.

研究原文：Guidance arithmetic implies H2 FY3/27 operating profit of about JPY 7,664m (JPY 15,000m less H1 JPY 7,336m), roughly a third below the about JPY 11,500m implied by the original forecast. The reset was delivered together with a first-half beat, so expectations are anchored low with evidence of conservatism; delivery at guidance would be a positive surprise against the reset, a second cut would confirm structural pass-through lag. Expectations are read from guidance and price only.

内部研究类型：ExpectationReset

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Risk/reward around the next print is unusually well defined because the implied H2 number is explicit.

不确定性（原始记录）：No analyst consensus or positioning data in the admitted sources; the 'original' H2 figure is derived by arithmetic from the prior forecast.

研究原文：H1 FY3/27 operating cash flow was -JPY 6,935m (versus +JPY 27,741m a year earlier) despite pre-tax profit of JPY 8,071m and depreciation of JPY 9,001m, because income-tax payments of JPY 16,294m (on the record FY3/26 result), a JPY 7,251m inventory build and a JPY 2,733m receivables increase absorbed it. Investing outflow was JPY 3,847m (JPY 5,635m investment-security sales against JPY 7,830m plant purchases); financing inflow was JPY 11,411m on JPY 26,000m of new long-term borrowing, JPY 8,052m repayments and JPY 4,875m dividends. Cash ended at JPY 32,878m. Best read as timing and working capital after a JPY 65,028m cash year, not a reversal of conversion capacity.

内部研究类型：CashConversionMechanism

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Weak halves are timing provided the full year converts; free cash flow funds returns in normal years without asset sales.

不确定性（原始记录）：Full-year FY3/27 conversion is not yet observable; the rationale for debt-funding the cash trough is inferred from sequence, not stated by the company.

研究原文：Growth costs cash in this model: inventories rose JPY 7,054m from March to JPY 60,818m and receivables stood at JPY 64,765m at September 2026; higher input prices inflate the yen value of the same physical stock, so a faster volume ramp or further scrap rally would consume cash even if reported profit held.

内部研究类型：WorkingCapitalMechanism

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Fast-growth or high-price years will show weaker cash conversion than profit years - structural, not a warning sign by itself.

不确定性（原始记录）：Inventory composition (raw versus finished), ownership/realisability, costing basis, ageing and supply-chain finance are undisclosed at interim level; inventory build is not treated as demand evidence.

研究原文：FY3/26 returns were funded substantially by balance-sheet conversion: about JPY 45.2bn was raised by selling nine listed policy shareholdings across FY3/25-FY3/26 plus shares in the retirement-benefit trust, funding about JPY 26.2bn of buybacks, about JPY 5.0bn of special dividend and about JPY 4.3bn of ordinary dividends. Retained earnings still fell in FY3/26 (JPY 137,666m to JPY 131,178m) because treasury-share cancellation charges exceeded net profit - a mechanical effect of the return programme, not an operating loss. Stated ordinary payout target is at least 40%.

内部研究类型：CapitalFundingMechanism

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Per-share value is advantaged over aggregate profit growth, but the funding stock shrinks with each sale.

不确定性（原始记录）：Remaining holdings by name and unrealised gains are annual-report detail; the buyback split between market and ToSTNeT-3 is not restated; tax leakage on sales is not analysed in sources.

研究原文：The balance sheet can carry the programme: at 30 September 2026 total assets JPY 405,646m, attributable equity JPY 238,497m (58.8% ratio; 59.2% in March), cash JPY 32,878m, borrowings JPY 67,415m (short-term JPY 41,403m, long-term JPY 26,012m, up from JPY 47,470m because funding was raised around tax and dividend dates), other financial assets JPY 66,625m and retirement-benefit assets JPY 25,886m. The ratio remains above the plan's 50-55% FY3/26 band and the roughly 50% 2030 level, so by the company's own framework excess capital remains after two years of enlarged returns; the constraint on returns is policy choice, not capacity.

内部研究类型：BalanceSheetStructure

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：A heavy equity base depresses ROE arithmetically; the programme treats the balance sheet itself as the funding source for per-share value.

不确定性（原始记录）：Maturity ladder of the enlarged borrowing and parent-available versus consolidated cash are annual-report matters; stress liquidity of listed holdings is assumed, not tested; pension assets are not freely distributable.

研究原文：A severe spread downturn would hit earnings and the share rating long before solvency: the loss-absorbing layer (58.8% equity ratio, JPY 32,878m cash, JPY 66,625m financial assets, JPY 25,886m pension assets) is several times the largest observed half-year spread swing of about JPY 10bn, and the forging franchise grew profit through the latest spread downturn. The cushion shrinks deliberately toward a ~50% ratio as returns are paid.

内部研究类型：DownsideProtection

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Permanent capital impairment is unlikely on any evidenced scenario; the realistic downside is years of low ROE and a persistent discount.

不确定性（原始记录）：Asset liquidity in stress, encumbrances and transfer frictions for listed holdings and pension assets are not publicly testable.

研究原文：Reported equity is unusually sensitive to securities and pension revaluation: total comprehensive income swung from -JPY 10,644m in FY3/25 to +JPY 39,006m in FY3/26 (roughly JPY 50bn) while net profit rose from JPY 7,820m to JPY 11,248m, and H1 FY3/27 comprehensive income fell 39.7% to JPY 7,229m despite positive net profit. Book value and PBR denominators therefore move with holdings' share prices, not operations (IFRS, voluntarily adopted from FY3/23).

内部研究类型：AccountingDistortion

不确定性（原始记录）：The securities versus pension split of FY3/26 comprehensive income is annual-report detail. No restatement or audit qualification seen.

研究原文：In H1 FY3/27 the company spent JPY 1,982m buying out minority interests in subsidiaries, reducing non-controlling interests from JPY 12,661m to JPY 9,658m, while equity-method investments stood at JPY 10,841m. The group is simplifying its structure while returning capital.

研究原文：Investment is maintenance-plus: FY3/27 capex is planned at JPY 19,000m (trimmed from JPY 20,000m) against depreciation of JPY 18,000m, and FY3/26 actual capex of JPY 16,928m was below depreciation of JPY 18,039m. The base is maintained and selectively extended (stainless furnace renewal announced March 2023, electrification lines), not aggressively expanded.

内部研究类型：InvestmentDiscipline

内部来源标记：COVERAGE35

普通股东含义（原始记录）：No growth-capex surge is funded that could surprise on returns; maintenance of the integration moat is preserved while the equity base shrinks.

不确定性（原始记录）：Project-level returns and decarbonisation capex schedule are undisclosed.

研究原文：The dividend is explicitly two-layered. FY3/26 paid JPY 145 per share (ordinary JPY 69 plus special JPY 76); FY3/27 is guided to JPY 142 (ordinary JPY 64 plus special JPY 78) after the year-end ordinary forecast was cut from JPY 75 to JPY 67 (ordinary 28 plus special 39) against an original FY3/27 plan of JPY 150; the interim was JPY 75 (36 plus 39). The special layer is a distribution of asset-recycling proceeds, not a claim on recurring earnings, and the stock of saleable policy shareholdings shrinks with each sale (nine issues already sold), so the forecast yield of about 5.9% steps down when recycling ends unless the ordinary payout rises. Headline yield overstates recurring yield by roughly the special layer's share - about half.

内部研究类型：ShareholderReturnStructure

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Only the ordinary layer should be capitalised as recurring yield; the special layer compensates part of the wait but is finite.

不确定性（原始记录）：The successor framework after the special layer is the key unknown; per-share figures are post-split basis.

研究原文：The share count is already shrinking: average shares fell about 5.2% year on year in H1 FY3/27 to 64,026,024 after FY3/26 buybacks and cancellations, following the 1-for-4 split of 1 July 2025 and buyback rounds in February and May 2025. EPS therefore rises mechanically even where net profit falls (H1 attributable profit -5.5%).

内部研究类型：PerShareMechanism

普通股东含义（原始记录）：Per-share metrics compound faster than aggregate profit; the denominator lever of the ROE bridge is demonstrably working.

不确定性（原始记录）：Weighted-average versus period-end basis matters for per-share conclusions; buybacks paused in H1 and resumption is unannounced.

研究原文：The February 2025 update of the 2024-26 mid-term plan sets FY3/26 targets of JPY 340,000m revenue, JPY 15,000m operating profit, ROE at least 4% and equity ratio 50-55%, and 2030 targets of JPY 400,000m revenue, JPY 28,000m operating profit (raised from JPY 20,000m mid-plan), ROE at least 8% and equity ratio about 50%, with ROE 8% and PBR 1.0 to be reached as early as possible; long-term ambition JPY 500,000m revenue and JPY 40,000m operating profit by 2040. FY3/26 operating profit already beat the plan's final-year target a year early, while ROE of 4.8% (FY3/27 forecast about 4.2%) is roughly halfway to the 2030 commitment.

内部研究类型：PlanTargets

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：The plan defines both levers of the equity story and the yardstick against which delivery will be judged.

不确定性（原始记录）：Segment bridges, structural spread assumptions, cost of capital and the year-by-year ROE path are undisclosed; 2030 elements are management targets.

研究原文：Normalised operating earning power is best read in the mid-teens of billions of yen: FY3/26's JPY 17,371m (favourable spread) and the cut FY3/27 guidance of JPY 15,000m (adverse spread) land in the same zone, but the JPY 28,000m 2030 target implies about a 7% operating margin on JPY 400,000m of revenue versus 5.7% in FY3/26, requiring both volume growth and structural margin work rather than spread luck.

内部研究类型：NormalisedEarningsJudgment

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Capitalising peak or trough earnings would misprice the shares; the mid-teens range is the valuation input and the numerator of the ROE bridge.

不确定性（原始记录）：Analytical construction from two observed spread regimes; the FY3/27 full year will tighten the range; the 7% margin is a derived figure.

研究原文：At the 6 November 2026 close the price was JPY 2,390, market capitalisation about JPY 154.2bn, trailing PBR 0.64x (observed range 0.18-1.07x since 2010; roughly 0.18-0.24x at the FY3/23 trough), forecast PER 15.36x and forecast dividend yield 5.94%. The market prices the shares below book despite record FY3/26 operating profit with JPY 66,625m of financial assets and JPY 25,886m of pension assets on balance sheet: the discount is a judgement that ROE stays near 4-5% rather than reaching 8%, i.e. a referendum on programme execution rather than asset value. The multiple has narrowed from the 0.2x era as delivery accumulated.

内部研究类型：ValuationState

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Upside is back-loaded into programme delivery; about half of the carrying yield is finite.

不确定性（原始记录）：IRBANK summary multiples at stated close; forecast multiples use revised guidance; no consensus; PBR denominator is sensitive to securities revaluation.

研究原文：The equity story is the compounding of two deliberate programmes: operating profit growing from the FY3/25 base of JPY 12,016m toward the 2030 target of JPY 28,000m, and an over-capitalised balance sheet converted into per-share value through asset sales, buybacks and cancellations. If both run, ROE rises toward 8% from both directions (numerator growth and denominator shrinkage), which a re-rating from 0.64x toward 1.0x book requires. Arithmetically, if operating profit compounds toward JPY 28,000m while the equity ratio converges from 58.8% toward about 50%, ROE approaches 8%; if either leg stalls the shares remain a low-multiple spread cyclical with a generous but finite special dividend.

内部研究类型：InvestmentThesis

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Per-share value compounds faster than aggregate profit when both levers move; the thesis is a programme, not a moment.

不确定性（原始记录）：Medium confidence; the successor return framework and 2030 segment bridges are the decisive unknowns; 2030 numbers are management targets.

研究原文：Fundamental falsifiers of the thesis: (1) operating profit stuck in the mid-teens with no path beyond, or the 2030 target abandoned or missed by a wide margin; (2) the return programme ending without a successor framework - special layer lapses, buybacks stay paused, equity ratio stuck near 59%; (3) a delivery miss at the FY3/27 year end (a second guidance cut would confirm structural pass-through lag). Coverage-35 Domain 35 also names a price-structure falsifier (a monthly close below the pre-2025 ceiling of about JPY 2,040), which is carried here as thesis context only; its technical meaning belongs to the independent Technical lane.

研究原文：The next hard catalyst is the FY3/27 year-end print against the cut JPY 15,000m operating-profit guidance: delivery would validate the 'one-off input wave' framing and the Q3 profit bridge will first show whether pass-through is catching up; a second cut would confirm structural pass-through lag behind scrap.

An anchor tightening, financial holders exiting and possible activists arriving can coexist in the same year. Jointly-held ratios are a different basis from the securities-report table percentages.

不确定性（原始记录）：Joint-holding basis versus register basis not reconciled; current activist stakes unconfirmed.

研究原文：Demand is a derived variable of Toyota-group vehicle production: H1 FY3/27 commentary ties volume growth to the recovery in finished-vehicle production at customers (forgings revenue +8.4%), while flagging US tariff measures as a headwind. Customer-level splits are not disclosed; the Toyota linkage is established through register, group identity and commentary.

内部研究类型：DemandMechanism

普通股东含义（原始记录）：Volume risk is effectively Toyota production risk, concentrated and correlated with the anchor shareholder's own cycle.

不确定性（原始记录）：Share of sales to Toyota Motor versus other makers and tariff exposure by destination are undisclosed.

研究原文：US tariff measures transmit through the customer: management flags them as a headwind to the production environment, and because forgings demand is derived from Toyota-group vehicle output, a tariff-driven production cut would arrive as a volume shock on top of the current spread squeeze, and tariffs also act through input prices.

Management's growth frame (electrified components plus Global South supply) underpins the path from JPY 304bn toward JPY 400bn of 2030 revenue.

内部研究类型：UnquantifiedOption

研究原文：Competition runs on two fields: special-steel supply against integrated makers such as the Nippon Steel group and electric-furnace makers such as Tokyo Steel and Yamato Kogyo, and input-side rivalry for the same domestic scrap pool. Competitors cap selling prices and bid up scrap, squeezing the spread from both sides, while Nippon Steel is simultaneously a 6.19% shareholder. Large-EAF capacity additions by integrated makers are a known future pressure.

普通股东含义（原始记录）：Margin ceilings in steel are set by rivals' capacity and scrap bidding, limiting how much of a demand recovery the steel segment keeps.

不确定性（原始记录）：Market shares by product and rivals' capacity schedules are not quantified.

研究原文：As an electric-furnace maker melting scrap, the process route is structurally aligned with carbon-reduction policy, and furnace renewal (stainless, announced March 2023) is the main regulatory-cycle investment; but decarbonisation also raises energy prices, which cost about JPY 0.6bn in H1 FY3/27.

研究原文：Cross-lane relationship, formed after both lanes were independently mature: the fundamental thesis and the price structure hinge on the same programme events - the February 2025 plan update, buybacks and cancellations, the share split, the record FY3/26 print and the October 2026 guidance reset. The fundamental view reads these as a spread-geared engine plus a capital programme; the price lane records its own response to them. Fundamental positivity (record profit, thesis arithmetic) is not used to upgrade the Technical State, which is a retention test and is not confirmed on its own evidence; likewise Technical weakness is not used to alter fundamental adjudication. The main joint observation points are the FY3/27 year-end print and the successor mid-term plan.

研究原文：Durable Business Portrait: integration chain inside the Toyota system with spread-geared earnings and an over-capitalised balance sheet｜The structure beneath the equity is more durable than its earnings line: an integrated material-to-component chain operating inside the Toyota system for eight decades, a stainless niche, equity at 58.8% with tens of billions of yen of saleable financial assets, and a modernised governance form. What is not durable by itself is any single year's profit: the scrap spread can move operating profit by more than JPY 10bn in a half, comprehensive income swings with the securities portfolio, and the special-dividend layer expires with the asset stock that funds it. The case rests on a programme - profit compounding toward 2030 while equity converges toward 50% - not a moment; self-repair capacity is strong in solvency terms and weak in earnings smoothness.
