ジェコス株式会社（GECOSS Corporation）

研究原文：GECOSS Corporation (ジェコス株式会社, 9991, TSE Prime, EDINET E02782, operating since 1968, listed 1994) is a heavy-temporary-works company: rental and sale of temporary steel materials, temporary-works design and construction, steel fabrication and bridges, plus construction-machinery rental, with a small Singapore/Vietnam cluster. FY3/26 sales were JPY 115,680 million; heavy temporary works is about 90% of sales and about 96% of gross segment profit. It is an equity-method affiliate of the JFE group (39.49% of votes) with Mizuho Lease at 20.04%; no holder has a majority.

内部研究类型：ENTITY_IDENTITY_AND_PERIMETER

内部来源标记：OPEN_DISCOVERY

普通股东含义（原始记录）：Fixes the investable perimeter: affiliate-not-subsidiary status and a two-anchor register define governance, float and valuation for ordinary shareholders.

不确定性（原始记录）：Content of the February 2026 representative-director change was read only from filing headers (Nobusa continuous as president).

研究原文：The revenue decline was a choice: FY3/25 sales fell 13.0% because management cut low-margin distribution sales from about 40% to about 25% of steel-material revenue while operating profit still rose 9.7%. Gross margin then compounded 20.9% (FY3/25) to 22.9% (FY3/26) to 23.5% (H1 FY3/27) on mix and price-adequacy work (consideration matched to design and execution cost); SG&A rose in absolute terms in both years, so the operating leverage is revenue-quality, not cost-cutting. Screening on revenue growth inverts the story. Segment margin of heavy temporary works stepped from 6.6% to 8.3% on the ordinary-profit basis.

内部研究类型：CAUSAL_MECHANISM_STRATEGIC_CHOICE

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：This is the engine of record operating profit and of the re-rating; it is a management-controlled mechanism, not a market gift.

不确定性（原始记录）：Distribution-suppression is described as having run its course, so future growth must be mix-neutral; ceiling of the programme is an open question (see Research Debt).

研究原文：FY3/26 must be read on the operating line. Operating profit JPY 8,012 million (+16.9%, record) sits below ordinary profit JPY 8,709 million (+28.2%), which contains about JPY 547 million of identifiable non-operating supports (FX gain 196, compensation received 94, securities-sale gain 47, equity-method swing to +210); special items add a net JPY 203 million (negative goodwill 401 and securities sale 220 against a FUCHI step-acquisition loss of 418). The company guided FY3/27 ordinary profit down at inception while guiding operating profit up (initial: operating JPY 8,400 million, ordinary JPY 8,600 million). Segment profit is defined on the ordinary basis, so segment margins are not operating margins.

内部研究类型：EARNINGS_QUALITY_BRIDGE

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Readers screening on ordinary or net profit misread both FY3/26 growth and later quarters; the recurring layer must be built from the operating line before any multiple means anything.

不确定性（原始记录）：Tax allocation between earnings layers uses the year's effective rate (33.1%); layer-by-layer tax split not published.

研究原文：Standalone Q2 FY3/27 ordinary profit was about JPY 2,092 million versus about JPY 2,226 million a year earlier (about -6%), while H1 operating profit grew 12.3%. Differencing proves that the ordinary line, not the business, deteriorated in that quarter, because the prior-year quarter carried part of FY3/26's non-operating supports. Q1 had printed ordinary profit of JPY 2,290 million (+20.8%) on a similarly distorted base.

内部研究类型：BASE_EFFECT_ANOMALY

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Quarterly prints of this company must be read on the operating line; an ordinary-line reader sees deterioration where the business improved.

不确定性（原始记录）：Standalone Q2 is derived by differencing, not directly reported.

研究原文：H1 FY3/27 grew without special items: sales JPY 57,095 million (+4.0%), operating profit JPY 4,190 million (+12.3%), gross margin 23.5%, operating margin 7.3%. On 5 November 2026 the company raised FY3/27 guidance to sales JPY 118,000 million and operating profit JPY 9,200 million (+14.8%), ordinary JPY 9,600 million, net income JPY 6,300 million, EPS JPY 187.24, and lifted the annual dividend forecast from JPY 69 to JPY 75 (about 40.1% payout). Comprehensive income fell 22.0% on a securities valuation reserve decline, a balance-sheet market effect, not an earnings effect.

内部研究类型：CURRENT_CHANGE_EVENT

内部来源标记：OPEN_DISCOVERY

普通股东含义（原始记录）：Second consecutive record operating profit if delivered, with a dividend increase sized to the existing ratio.

不确定性（原始记录）：Delivery depends on the implied second half; the Q3 tanshin is the first check.

研究原文：Subtracting H1 actuals from the revised forecast requires a second half of JPY 60,905 million sales (+0.2% year on year) and JPY 5,010 million operating profit (+17.0%; ordinary +13.8%, net income +11.3%), an implied operating margin of 8.2% versus 7.0% in H2 FY3/26 and 7.3% in H1 FY3/27. Seasonality is normal (H1 delivered 45.5% of the revised full-year operating profit versus 46.6% a year earlier), so this is a margin promise, not a demand or phasing promise. Two quarters decide it; the first prints late January / early February 2027.

内部研究类型：FALSIFIABLE_FORECAST_ARITHMETIC

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Concentrates the year's verdict and management credibility in one checkable margin step.

不确定性（原始记录）：Error bars on embedded margins cannot be computed from primary sources because no order backlog is disclosed.

研究原文：The revised forecast's demand is specific and fragile: flat second-half sales with a 17% operating-profit increase requires the gross-margin programme to compound for two more quarters in an environment the filings describe as tight labour and high construction costs, with some projects revised, cancelled or postponed.

内部研究类型：RISK_CONDITION

内部来源标记：OPEN_DISCOVERY

普通股东含义（原始记录）：A miss would test whether the margin programme has a ceiling below the guided level and weaken the credibility behind the capital argument.

不确定性（原始记录）：Magnitude cannot be sized without backlog disclosure.

研究原文：Fixed-price exposure runs through the works book: revenue is contracted before costs are final, labour is tight and materials are dear, and no backlog is disclosed against which to stress embedded margins. The filings name both the headwind (labour and materials cost) and the countermeasure (obtaining consideration commensurate with design cost), so margin is a two-sided contest between realized prices and realized costs on work already contracted.

内部研究类型：RISK_CONDITION

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Margin timing risk between contract price and completion cost sits with shareholders.

不确定性（原始记录）：The fixed-price share of the contracted book is not disclosed.

研究原文：A first-time provision for loss on orders of JPY 314 million appeared on the FY3/26 balance sheet, proving at least one contract was priced below completion cost in the very years the pricing programme is the thesis. It is unexplained: it is not known whether it attaches to one contract or a class. If Q3 or full-year prints enlarge it, the premise that pricing discipline is now systematic weakens at its foundation.

内部研究类型：EARNINGS_QUALITY_CRACK

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Early-warning signal on the central pricing mechanism; small in yen, large in what it could falsify.

不确定性（原始记录）：Counterparty, contract history and direction of movement unknown.

研究原文：Contract liabilities (customer advances) rose 75.1% from JPY 3,285 million to JPY 5,751 million in FY3/26, about 5.0% of sales and about 19% of the receivables-and-contract-assets book, inside current liabilities that rose only 10.5%. With no order backlog disclosed, this is the closest forward-demand sensor in the filing set, consistent with works growth (+17.6%) and smooth project starts: forward demand is corroborated by prepayment behaviour but not quantified.

内部研究类型：DEMAND_SIGNAL

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Substitute for a backlog; a rising balance supports the second-half delivery, but advances are not recognized revenue or cash earned.

不确定性（原始记录）：Absence of a backlog series is a disclosure limitation, not negative evidence; advance terms by contract unknown.

研究原文：The balance sheet is close to debt-free and self-funded: at September 2026 cash JPY 12,404 million and investment securities JPY 4,861 million against borrowings JPY 3,280 million; equity ratio 59.2%; interest-bearing debt about 0.05 times equity (company-disclosed JPY 3.7 billion at FY3/26 including leases); interest paid only JPY 71 million. Total assets JPY 121,785 million include rental steel JPY 28,591 million, receivables and claims JPY 33,582 million and land JPY 13,165 million at cost. Receivables allowance is trivial (JPY 61 million).

内部研究类型：FINANCIAL_STRUCTURE

内部来源标记：COVERAGE35 / OPEN_DISCOVERY

普通股东含义（原始记录）：Solvency is not a research question here; the constraint is the return earned on the asset pile.

不确定性（原始记录）：Receivable ageing, committed lines and covenants not disclosed.

研究原文：Net financial assets were about JPY 14.0 billion at September 2026 (cash 12,404 plus securities 4,861 less borrowings 3,280), about 24% of the roughly JPY 59.3 billion market capitalisation and about 19% of book equity (FY3/26: JPY 13,259 million). The securities portfolio moves with markets (valuation reserve fell JPY 554 million in H1). A retirement-benefit asset of JPY 6,336 million against a JPY 445 million liability is real but not distributable and is excluded; land is at historical cost with no appraisal.

内部研究类型：HIDDEN_ASSET_VALUATION_COMPONENT

内部来源标记：COVERAGE35

普通股东含义（原始记录）：The financial sleeve is downside ballast and the natural funder of buybacks, special dividends or acquisitions; it belongs in valuation as an additive piece, not as earnings.

不确定性（原始记录）：Net financial assets here count securities at market and exclude pension and land; the EV in the valuation snapshot nets cash only, so the two EV bases differ.

研究原文：Cash conversion is structural: FY3/26 operating cash flow JPY 10,661 million was 1.8 times net income (depreciation 3,288, receivables decrease 2,979, inventory decrease 945, less payables decrease 4,124 and tax 2,365); H1 FY3/27 added JPY 4,705 million. The FUCHI and JS Tan acquisitions, rising dividends and the transformation were all funded without net borrowing. Payables and receivables swing JPY 3-4 billion between prints on project timing, so single-year conversion should not be annualized.

内部研究类型：CASH_MECHANISM

内部来源标记：COVERAGE35

普通股东含义（原始记录）：The model self-funds its growth and distribution; cash-based valuation must use multi-year sums.

不确定性（原始记录）：FY3/27 full-year operating cash flow against revised profit is not yet known.

研究原文：The return contract is a de facto rule, not a stated one: payout ratios of 40.1% (JPY 54), 39.7% (JPY 69) and a forecast 40.1% (JPY 75) across three years; year-end dividends raised at earnings prints (January 2026; November 2026 interim JPY 27, year-end JPY 48). Buybacks were effectively nil in FY3/26 despite net financial assets of about JPY 14.0 billion; treasury shares are 0.44% of issued; the last buyback was a 2023 ToSTNeT-3 purchase with cancellation. The board treats the ratio as the commitment and the yen amount as the residual; formalisation is a free catalyst not yet used. Forecast yield is 4.27%, covered about 1.9 times by recurring earnings.

内部研究类型：CAPITAL_RETURN_RULE

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Income holders can underwrite the dividend; the buyback is unpriced optionality on top. No formal payout target was found.

不确定性（原始记录）：Rule is behavioural; dividend per share is not affected by the recurring/reported distinction except through the formula.

研究原文：The board is managing the register as deliberately as the P&L: two dividend raises in 2026, a revived shareholder-benefit scheme (introduced May 2026, a predecessor having been abolished in 2016), an audit-and-supervisory-committee transition with voluntary nomination and compensation committees (effective June 2026), and repeated individual-investor seminars. It is a coherent programme to broaden the marginal buyer base of a stock whose float cannot broaden by itself; if it works, a liquidity discount compresses independently of ROE.

内部研究类型：MANAGEMENT_BEHAVIOUR

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Spending effort on the register's composition, not only its returns, is evidence of intent toward re-rating.

不确定性（原始记录）：Instruments are small in yen terms; effect on liquidity unproven.

研究原文：Non-controlling interests rose from JPY 5 million to JPY 4,403 million in FY3/26 (JPY 4,462 million at September 2026) on the FUCHI consolidation (30% minority) and the Rental System allotment (JPY 1,580 million paid in), and took JPY 107 million of FY3/26 and JPY 114 million of H1 FY3/27 net income, about 4% of group profit. Minorities sit in the two growth vehicles (Singapore, machinery).

内部研究类型：PER_SHARE_ATTRIBUTION

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Parent per-share growth will lag group growth while overseas and machinery vehicles outperform.

不确定性（原始记录）：Future minority share depends on the growth vehicles' relative profit.

研究原文：The mid-term plan's PBR target (at least 0.8 times by FY3/28) has effectively been met two years early: just under 0.5 times (September 2024), about 0.7 times (November 2025), 0.82 times (November 2026 aggregator snapshot). Book value per share rose from JPY 1,970 to JPY 2,119 to about JPY 2,144, so roughly half the re-rating was earned in the book and half in the price. The debate shifts from whether re-rating happens to whether ROE can be carried high enough to argue for parity (1.0 times); an early-met target raises the evidentiary weight, and the cost of missing, of the next target.

内部研究类型：CAPITAL_TARGET_DELIVERY

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Defines how much of the re-rating is behind the holder and what must now come from ROE evidence instead of multiple expansion.

不确定性（原始记录）：Attribution between book growth and price is arithmetic from per-share book at different dates; 0.82 versus 0.83 reflects book basis.

研究原文：Recurring ROE is lower than reported and rising into the forecast: about 7.8% for FY3/26 after removing one-off layers from the reported 8.5% (numerator from operating profit JPY 8,012 million taxed at 33.1%, about JPY 5.36 billion, on average equity of about JPY 68.8 billion), against 7.0% reported for FY3/25 and a forecast 8.73% for FY3/27. Segment returns on assets are 7.2% (heavy temporary) and 4.1% (machinery) on the ordinary basis. The level that decides the PBR argument is the high single digits, approached but not yet reached.

内部研究类型：CAPITAL_EFFICIENCY

内部来源标记：COVERAGE35

普通股东含义（原始记录）：The discount to book is the market's verdict that recurring returns still trail the cost of equity; closing it requires ROE evidence.

不确定性（原始记录）：Reported ROE (8.5%) vs recurring (7.8%) vs forecast (8.73%) are on different bases; ROIC by field and the cost of equity are not disclosed or estimated.

研究原文：The valuation discount is a register and ROE discount, not an earnings-quality discount: at 9.4 times forecast earnings, 0.82 times book and an enterprise value of about JPY 45.3 billion (about 4.9 times forecast operating profit; net of net financial assets of about JPY 14.0 billion), the market pays single-digit multiples for itemised earnings from a net-cash issuer because 60% of votes are anchored, float is thin and ROE still trails the return the market demands for parity. Value resolves into three additive pieces: the operating engine at a single-digit multiple, the financial sleeve at face value, and the optionality of capital formalisation and the next plan; the price pays for the first and part of the second.

内部研究类型：VALUATION_JUDGMENT

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Risk-reward is balanced-to-favourable for holders who can wait for two verdict prints; the discount has a mechanical expiry if recurring ROE reaches double digits or the sleeve is returned.

不确定性（原始记录）：No target price or DCF is asserted; the multiple the market applies to FY3/27 and FY3/28 guidance is unknown.

研究原文：Valuation snapshot (price at the 6 November 2026 close; research cut-off 9 November 2026): price JPY 1,755; market capitalisation JPY 59.31 billion (x 33,795,746 issued shares); forecast PER 9.4x on revised FY3/27 EPS JPY 187.24; actual PBR 0.83x on FY3/26-end net assets per share JPY 2,118.51; ROE 8.5% (FY3/26 reported); forecast dividend yield 4.27% on JPY 75; EV/EBITDA 4.4x (EV JPY 50.19 billion = market cap less net cash JPY 9,124 million, i.e. cash and deposits 12,404 less borrowings 3,280 at 30 September 2026; EBITDA JPY 11,300 million = FY3/26 operating profit 8,012 plus depreciation 3,288).

内部研究类型：VALUATION_SNAPSHOT_WITH_BASIS

内部来源标记：OPEN_DISCOVERY

普通股东含义（原始记录）：Reference multiples at the review cut-off; each is a derived value whose basis must travel with it.

不确定性（原始记录）：Bases differ across the map: PBR 0.83x uses FY3/26 book (JPY 2,118.51) while 0.82x uses September book (about JPY 2,144); EV/EBITDA 4.4x nets cash only and uses trailing EBITDA, whereas the EV of about JPY 45.3 billion nets securities too; share denominator is issued shares including 149,533 treasury shares (0.44%); PER is on a company forecast, not actual or consensus.

研究原文：Control is anchored but not held: JFE Steel directly holds 27.63% and JFE Holdings 39.49% in aggregate, making GECOSS an equity-method affiliate, not a subsidiary; Mizuho Lease holds 20.04% as shareholder and capital-and-business alliance partner; positions are essentially unchanged since June 2024 (27.62% / 39.47% / 20.03%). Together the anchors hold about 60% of votes, leaving a free float of about 40% (roughly 13.6 million shares) and average daily traded value of only about JPY 92 million; margin short interest is effectively absent and beta is 0.53. Position entry and exit are multi-day exercises, and the price record's smoothness is partly a liquidity artefact.

内部研究类型：OWNERSHIP_REGISTER

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Liquidity, not control contests, is the ownership issue for outside holders until the day it is control.

不确定性（原始记录）：Trust-bank and institutional holdings behind the anchors were not extracted; large-shareholding filings not read.

研究原文：The two anchors pull in different directions: JFE seeks a stable steel-value-chain affiliate (four secondees, shared steel customer and supplier relations); Mizuho Lease seeks a leasing partnership monetised through the machinery business and Rental System (one director, one secondee). The company says it consults and reports to both in advance on risk matters but decides independently, with no material transactions noted. The record since 2024 - a margin-first strategy neither anchor would naturally impose, executed without disclosed objection - supports that operating management is genuinely setting the agenda: a negotiated autonomy.

内部研究类型：GOVERNANCE_MECHANISM

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Governance is a tailwind for the capital thesis and the register's defining risk at once.

不确定性（原始记录）：Inference from behavioural timing, not from board minutes; attribution of the capital turn to either anchor is not proven.

研究原文：Mizuho Lease is the register's plausible change agent: a leasing specialist holding 20.04%, co-invested inside Rental System and partnered in the machinery segment, has both incentive and vocabulary to press the capital questions (formalised payout, fleet returns, the unused buyback). The capital programme's acceleration dates from its April 2024 entry.

内部研究类型：CAUSAL_HYPOTHESIS

内部来源标记：COVERAGE35

普通股东含义（原始记录）：If correct, the next phase of capital discipline has an identifiable sponsor on the register.

不确定性（原始记录）：Timing correlation only; the counter-reading is that operating management originated the programme (see anchor tension). Alliance terms beyond disclosed structures are not public.

研究原文：Anchor risk is low-probability and total: a JFE decision to consolidate or sell, or a Mizuho decision to exit, would re-rate the stock violently in one disclosure, and the same thin float that smooths ordinary trading would make any anchor-sized flow disorderly. Nothing in the record suggests movement and nothing would precede it but a disclosure.

内部研究类型：REGISTER_REGIME_RISK

内部来源标记：COVERAGE35

普通股东含义（原始记录）：A regime event rather than a trade, in either direction.

不确定性（原始记录）：Probability cannot be estimated from public information.

研究原文：Profit concentration is extreme and disclosed: heavy temporary works supplies about 95.7% (FY3/26) and 95.2% (H1 FY3/27) of gross segment profit (ordinary basis: JPY 8,604 million and JPY 4,403 million versus machinery JPY 391 million and JPY 220 million), and holds JPY 119,607 million of JPY 122,537 million of total assets. The machinery segment's H1 improvement leaned partly on used-asset sales, and the overseas cluster's contribution is undisclosed. Diversification is by field (materials 62,039 flat; works 30,039 +17.6%; fabrication 11,565 -5.2%) and geography inside one segment, not across segments: the group is for profit purposes a single segment's pricing discipline.

内部研究类型：STRUCTURAL_FRAGILITY

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：The thesis is a single engine; monitoring belongs at segment level, not group level.

不确定性（原始记录）：Shares are on the ordinary-profit basis and gross of the consolidation adjustment; no finer revenue split of the materials field (rental versus sale).

研究原文：Heavy temporary works earns a 7.2% ordinary return on segment assets of JPY 119,607 million, while construction machinery earns 4.1% on JPY 9,534 million (2.6% margin on JPY 14,765 million of sales) and consumes JPY 1,746 million, over half, of group depreciation of JPY 3,288 million. The fleet (JPY 4,065 million net at FY3/26, JPY 3,715 million at September 2026) is being optimised by replacement and used-asset sales; machinery is where capital productivity, not demand, is the constraint, and the Mizuho / Rental System alliance (September 2025) is aimed at exactly this.

内部研究类型：CAPITAL_PRODUCTIVITY_PROBLEM

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Small segment (about 4% of gross segment profit) but the one place the group admitted an outside co-owner; improvement would lift group ROE at the margin.

不确定性（原始记录）：End-state fleet size, utilisation and alliance economics undisclosed; segment returns are ordinary-basis.

研究原文：GECOSS is a margin transformation compounding inside an anchored register: a company that deliberately shrank revenue to clean its mix now converts it into record operating profit (JPY 8,012 million, then JPY 9,200 million forecast), funds a 40%-payout dividend yielding 4.27% from a near-debt-free balance sheet, and has just crossed the 0.8-times-book target at 0.82 times. It works if the implied second half is delivered (operating profit JPY 5,010 million, +17%, flat sales), the FY3/28 guidance in May 2027 carries the margin programme and capital questions into the plan's final year, and the price holds its 2025-2026 breakout. It fails if the margin programme stalls (cost inflation outpacing price adequacy), or if either anchor's stance changes the company's status. Risk-reward at the review date is balanced-to-favourable for patient holders and is not a momentum proposition.

内部研究类型：THESIS

内部来源标记：OPEN_DISCOVERY / TECHNICAL

普通股东含义（原始记录）：The adjudicated investment judgment; conditional on dated verdicts, not a forecast of the construction cycle.

不确定性（原始记录）：Counter-evidence: the loss-order provision, fixed-price exposure and the unproven overseas contribution; the thesis's technical clause refers to the protected Technical structure and does not alter it.

研究原文：Fundamental kill set: the implied second half misses widely (margin-programme ceiling), the loss-order provision grows, the FY3/28 framework abandons the capital programme, or an anchor changes the company's status. Confirm set: FY3/27 delivered at or above JPY 9,200 million operating profit and a successor framework with numeric ROE and return commitments. Early warning signs: two consecutive quarters of field contraction, a growing loss-order provision, or an anchor-shareholder filing. Confirmation is provisional: delivery re-opens the question at FY3/28's mix and costs. Price-structure confirmation and failure levels live in the protected Technical structure and are not restated here. Excluded upsides: fleet utilisation economics, land value; unsized: the overseas cluster's profit. The falsification window closes with the May 2027 print.

内部研究类型：FALSIFICATION_AND_CONFIRMATION_SET

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Lets the Thesis be held to its own standard: two prints decide it.

不确定性（原始记录）：The first failing signpost, if any, is unknown.

研究原文：Nearest dated verdicts: the JPY 27 interim dividend payable from 1 December 2026; the Q3 FY3/27 tanshin (late January to early February 2027; Q3 FY3/26 was 29 January 2026, external calendars point to 2 February 2027), which prints the first quarter of the implied second half against the 8.2% margin requirement, shows whether contract liabilities and the works field keep building, and may carry a year-end dividend adjustment on the January 2026 precedent; the FY3/27 full-year print in May 2027, which delivers the plan's second-year score, FY3/28 guidance for the plan's final year and the JPY 48 year-end dividend; the June 2027 AGM. Between this review and May there is exactly one earnings verdict.

内部研究类型：CATALYST_CALENDAR

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Position timing should be built around the two prints rather than the tape of a thin-float stock.

不确定性（原始记录）：Dates are patterned expectations, not confirmed; unscheduled catalysts (anchor filings, large orders, M&A) cannot be calendared.

研究原文：Formalisation is the cheapest available catalyst: a stated payout ratio or DOE floor, a first buyback authorisation or treasury cancellation, or publication of the mid-term plan's final-year numerical targets would each convert observed behaviour into commitment; the May 2027 print, which sets FY3/28 guidance for the plan's last year, is the natural venue for all three.

内部研究类型：CATALYST_OPTION

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Unpriced upside in the board's gift that does not require better operating numbers.

不确定性（原始记录）：The board may choose not to formalise; absence of numbers would itself be the answer.

研究原文：Downside is built from asset and income absorbers, not leverage: book equity JPY 72,128 million against about JPY 59.3 billion market capitalisation; net financial assets about JPY 14.0 billion; JPY 75 dividend covered about 1.9 times by recurring earnings and raised at each of the last two revision points; and a demand base that carried the worst recent year (FY3/23 ordinary profit JPY 4,903 million) to a smaller profit, not a loss. A digestion year at trough multiples of trough recurring earnings could plausibly cost about a third of the price, but not the position on observed precedent. There is effectively no debt to amplify a downturn.

不确定性（原始记录）：Scenario probabilities are not asserted; inventory and land are carried at book/cost with no haircut analysis, and the fleet's realisable value is unknown.

研究原文：Three price-structure Claims are retained as stated by Research without restating the Technical Synthesis: (a) the June 2026 retracement low of JPY 1,443 landed on the 2015-2024 residence top that the 2025 close of JPY 1,451 first exceeded, read as the ceiling retested as a floor, unlike 2014's first pullback which was never stopped; (b) the 2026 advance's heaviest month (March 2026, 1,998,900 shares) was about 59% of the April 2015 distribution climax (3,391,600) with twelve-month volume up 14.8%, so the advance has not yet printed a distribution signature; (c) at 88.8% of life range, above 97.4% of monthly closes and all three averages but only 9.0% below the highest close, the chart reads as a held verdict awaiting the earnings prints.

研究原文：Durable business portrait and structural durability of GECOSS｜A rental-steel fleet plus engineering niche attached to every construction project in the capital region and public sector, earning about 96% of gross segment profit in one segment, self-funded with an equity ratio near 59% and effectively no debt, distributing about 40% of earnings, with a financial sleeve of about JPY 14.0 billion. Durable: temporary-works demand, fleet availability and engineering references, balance sheet, and demonstrated management behaviour (a revenue sacrifice accepted to fix mix, dividend raises sized to a ratio, bargain-priced expansion). Fragile in two specific ways: profit concentration in one engine's pricing discipline, and a register where two anchors hold about 60% of votes, which stabilises everything until one moves. Confidence rests on observable dated mechanisms (gross-margin line, payout ratio, advances balance, anchors' filings), not on a forecast of the construction cycle. Current change (record operating profit, raised forecast) is overlaid on this foundation, not substituted for it.

研究原文：Chosen revenue sacrifice to clean mix to margin to record operating profit to a checkable second-half promise｜Volume-first selling pushed ordinary profit down two years; management cut distribution sales, accepted a 13.0% revenue fall, and compounded price-adequacy on the cleaned mix. Gross margin 20.9% to 22.9% to 23.5% produced record operating profit and a raised forecast whose implied second half (8.2% operating margin on flat sales) is a pure margin promise. The chain is read on the operating line because one-offs distort the ordinary line and standalone quarters. Counter-evidence: tight labour and high costs, fixed-price contracting without disclosed backlog, and an unexplained JPY 314 million loss-order provision.

研究原文：Exchange pressure, anchored register and the capital programme｜A dated external commitment (PBR at least 0.8 times) converted an anchored register into margin, dividend, engagement and governance actions; the target was met two years early, half through book growth and half through price. The next stage is an ROE argument for parity with book, with a 40% informal payout, an unused buyback and a net financial sleeve as the unpriced capital instruments, and Mizuho Lease as the plausible financial-owner sponsor. Policy support is rented, not owned.
