株式会社イボキン（IBOKIN Co.,Ltd.）

研究原文：IBOKIN (5699) is a Hyogo-based demolition-and-recycling group whose three segments are one physical chain. Demolition wins and executes the dismantling, environment collects, treats and landfills the waste, and metals processes and sells the scrap. Each demolition mandate therefore produces three revenue events (the contract, the waste flow and the scrap flow), so chain capture is the unit of value, not segment share. FY12/25 sales were demolition JPY 3,461m, environment JPY 2,026m and metals JPY 4,519m.

内部研究类型：business_model_chain

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Earnings quality depends on chain capture rates and any internal transfer pricing, neither of which is disclosed. Segment profit is the only observable proxy.

不确定性（原始记录）：Inter-segment transfer pricing and chain-level economics are not disclosed.

研究原文：Demolition is the swing segment because its profit is made or lost in cost estimation on a few large projects, not in demand. FY12/25 revenue rose 36.7% while segment profit fell 43.7% to JPY 203m on estimate misses. In H1 FY12/26 segment profit moved from a JPY 56m loss to a JPY 192m profit as those projects rolled off, a swing of about JPY 248m, and this drove group operating profit up 135.2% to JPY 435m on sales of JPY 4,905m. Environment contributed JPY 116m and metals JPY 127m. H1 operating margin was 8.9%, up from 4.0%. The open question is whether the repair is a durable capability or the absence of last year's bad projects.

普通股东含义（原始记录）：This one variable drives group earnings volatility, the normalised band, the valuation discount and the verdict on the thesis.

不确定性（原始记录）：Project-level margin dispersion and win rates are undisclosed. One clean half cannot separate capability from roll-off arithmetic.

研究原文：Metals and environment are scrap-price takers earning a processing margin, and the same price also touches demolition through recovered-scrap value. In H1 FY12/26 a ferrous average about 19% higher lifted metals profit. Environment profit eased because the prior year held an unusually valuable one-off job. In FY12/25 the average fell and revenue dropped in both segments. A price reversal therefore hits two segments at once, so the diversification is operational, not economic. The H2 FY12/26 price path is unobservable at the freeze date.

内部研究类型：external_price_exposure

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Earnings should be capitalised at mid-band, not at a single print. Net cash, not hedging, is the defence.

不确定性（原始记录）：No external price series was used and no sensitivity table is published. Scrap pricing in H2 FY12/26 is unknown.

研究原文：FY12/25 net income rose 15.0% to JPY 598m while operating profit fell 19.5%, because about JPY 140m of special profits sat below the ordinary line. These were a JPY 62.6m negative-goodwill gain on the Mitsue acquisition and JPY 77.7m of insurance income. The FY12/26 forecast net decline of 12.4% is the mirror image. Printed net income overstates recurring power by roughly a fifth. The negative goodwill reflects a cheap acquisition and the insurance income is cash, but neither recurs.

研究原文：About half the votes sit in the founding bloc: HS Kosan 38.94% and founder-president Katsumi Takahashi 11.07%. The register below that is dispersed and has no institutional holder of consequence. Capital policy, succession and any re-rating event are decided inside the founding perimeter. Control and capital are one story: a flat dividend, small buybacks and expansion funded by debt, not distributions or equity. A directors' retirement allowance of about JPY 300m sits on the balance sheet, and no succession arrangement is disclosed. The group has 191 consolidated employees. The founder's programme (Mitsue, Suminoe) was executed fast, which brings key-man exposure with it.

研究原文：The 21 April 2026 Mitsui & Co. MOU has four workstreams: a stable scrap supply system to major steelmakers, material-balance and carbon data, IBOKIN's participation in Mitsui-group demolition projects (stated as already beginning), and soil-remediation expansion support. It attaches no volumes, prices, exclusivity or dates, and nothing in the FY12/26 forecast depends on it. It is an option on volume quality and scrap realisation, not current revenue, and the price does not appear to pay for it. Its conversion into disclosed transactions is the catalyst to verify.

研究原文：Kunitora Kogyo Co., Ltd. has been a wholly owned subsidiary since April 2017. It shows the group uses small acquisitions to internalise processing and works capacity, a template the Mitsue deal repeated at larger scale.

普通股东含义（原始记录）：Evidence of a repeated capacity-by-acquisition pattern.

不确定性（原始记录）：Standalone economics are not disclosed.

研究原文：Mitsue Co., Ltd. has been consolidated since January 2025 (90.9% held). It brought asbestos removal, demolition construction and large heavy machinery in-house. It was acquired below net asset value, producing the JPY 62.6m negative-goodwill gain, and it created the group's first minority interest (about JPY 30m). Consolidated FY12/25 ordinary profit exceeded the parent's by about JPY 101m on JPY 451m more sales, so subsidiaries are net contributors and the FY12/25 profit decline was a parent demolition-estimation event. In-house capability widens the biddable project set and removes a subcontractor margin layer on the high-difficulty work whose pricing caused the overruns.

内部研究类型：acquisition_capability

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：It mechanically supports the margin-repair thesis. The low purchase price signals a thin seller's market for such capacity.

不确定性（原始记录）：Mitsue's full-year contribution to the earnings band is not yet observable.

研究原文：Demolition demand is a stock-turnover flow set by the age of Japan's building and plant stock. The plan frames over JPY 3,000 trillion of cumulative construction stock reaching renewal age, so the pool grows for decades. The environment waste volume leg is flat or shrinking at this company. Backlog cover is only about one quarter of segment run-rate (JPY 618m at June 2026; JPY 829m at FY12/25), so visibility is good at industry level and weak at company level.

内部研究类型：end_market

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Capacity, not order demand, is the growth constraint. Environment volume growth should be discounted.

不确定性（原始记录）：Independent market-size data for Japanese demolition was not obtained, and the framing is the company's own plan.

研究原文：The FY12/26 forecast was left unchanged at the interim print (sales JPY 10,500m, operating profit JPY 800m, ordinary JPY 778m, net JPY 524m, EPS JPY 159.42). H1 delivered JPY 435m of operating profit, so the implied H2 is JPY 365m of operating profit on JPY 5,595m of sales and JPY 237m of net income, about 16% below H1. The reading that fits the post-overrun experience is prudence: guide to what the project book can certainly deliver and let completions surprise upward. The alternatives are a known softer project mix, or costs at Suminoe and in hiring.

内部研究类型：forecast_arithmetic

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Delivery at merely the implied level validates prudence. A second forecast cut would reopen the estimation-credibility question.

不确定性（原始记录）：Management's reason is not disclosed. Prudence versus a soft patch is unresolved until the Q3 and annual prints.

研究原文：Quarterly profit is project-completion driven. Q1 FY12/26 produced JPY 269m of operating profit (about 62% of H1) and the implied Q2 about JPY 166m. This is the reverse of the prior year, when a weak H1 became a strong H2. Half-year and full-year prints are the smallest units that carry signal, and quarters should not be annualised.

研究原文：The 2024-2026 medium-term plan will miss its final-year headline targets. FY12/26 guidance (sales JPY 10.5bn, operating profit JPY 800m) concedes the JPY 11.5bn and JPY 900m targets, and it was conceded in February, before any quarter of the year. KPIs are mixed: the scrap-mix shift is achieved (74,484 tonnes handled against a 77,000 target), environment intake is behind its 2023 start (21,395 against 22,000), and supervisors are far behind (against 56). The miss is a capacity story, not a demand story. The plan stages 2024-2028 as investment and recovery from 2029, with a 2033 vision of JPY 30bn sales and JPY 2.5bn operating profit, about triple FY12/25 sales. The five-year consolidated operating-profit path (486/584/799/643, 800 forecast) shows step-like growth. The next plan, expected around the February 2027 results, will show whether the 2033 vision and capital policy survive the 2024-2026 delivery record.

研究原文：Licensed site supervisors are the binding constraint on demolition capacity. The count went 26 (2023), 41 (FY12/25 year-end), 38 (June 2026) against a target of 56 for end-2026. The target now needs about eighteen net additions in six months. Two Indonesian trainees were hired in April 2026, with fourteen more planned, but the licensed layer that legally gates project execution is not growing. The question is attrition, reclassification or hiring failure.

内部研究类型：capacity_constraint

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Growth, plan credibility and the capacity to take large projects all scale with licensed headcount, so a hiring disclosure is a strategy disclosure.

不确定性（原始记录）：The cause of the decline is undisclosed. The trainee pipeline has a long lag.

研究原文：Interest paid rose roughly twelvefold to JPY 19.4m in H1 FY12/26 from JPY 1.6m while borrowings fell from JPY 1,096m to JPY 860m. The company attributes it generally to borrowing accompanying capital investment. The amount is small against JPY 431m of ordinary profit. If it is fees or a rate reset it is a one-off, but if marginal funding cost has structurally risen, the debt-funded capacity model carries a higher hurdle.

普通股东含义（原始记录）：Absolute materiality is capped by size. It matters as a signal of funding-cost structure.

不确定性（原始记录）：Whether rates are fixed or floating, and the facility terms, are undisclosed. It is recorded as a fact to clarify, not interpret.

研究原文：FY12/25 operating cash flow was only JPY 72m (JPY 932m the prior year) on JPY 796m of pre-tax profit, because receivables and contract assets rose 57% (JPY 1,093m to JPY 1,722m, a JPY 615m cash absorption) on 3.6% sales growth, with JPY 342m of tax also paid. H1 FY12/26 reversed part of this: operating cash flow was JPY 1,043m, with a JPY 228m receivable decrease and a JPY 150m rise in contract liabilities. In completion-heavy periods profit runs ahead of cash, and one large project's billing can move annual cash by hundreds of millions of yen. A completion-heavy H2 FY12/26 could repeat the pattern even if the profit forecast is met.

内部研究类型：cash_conversion_risk

普通股东含义（原始记录）：Cash conversion must be judged over two-year windows. A weak cash print alongside a met profit forecast would not alone break the thesis.

不确定性（原始记录）：Receivable ageing, disputes or retention balances and customer concentration are undisclosed.

研究原文：The balance sheet funds the growth programme without equity dilution. FY12/25 was the expansion year: land rose JPY 870m to JPY 1,950m on the Suminoe acquisition, lease assets rose JPY 98m to JPY 461m, long-term borrowings rose to JPY 802m on JPY 900m of new facilities, total assets grew 28% to JPY 8,105m, and capex was JPY 1,437m against depreciation of JPY 344m. Capital has been unchanged since incorporation and growth is funded by retained earnings, bank debt and leases. At June 2026 the equity ratio was 63.9%, cash and deposits were JPY 2,275m against JPY 860m of borrowings, and the group was net cash. Slow growth and no dilution are two sides of one policy.

研究原文：Downside protection is concrete for a company this size. Net cash is about JPY 1.4bn, the equity ratio is 63.9%, and land is carried at JPY 1,828m. Parent equity is JPY 5,362m, about 116% of the roughly JPY 4.6bn market capitalisation at the 6 November 2026 close. The dividend was held through the FY12/25 profit fall. Protection limits the severity of loss, not its duration, so the downside case is a long stay at a discount, not insolvency.

内部研究类型：downside_protection

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：The protection argues for patience capital, and exit would be at a discount on thin volume.

不确定性（原始记录）：Protection is measured on book values. Realisable values in a stress sale are not disclosed.

研究原文：Normalised earnings power is anchored on ordinary profit. The parent's five-year ordinary profit has oscillated between JPY 545m and JPY 824m with no trend. Consolidated ordinary profit was JPY 824m in FY12/24 and JPY 666m in FY12/25, and the FY12/26 forecast is JPY 778m. The normalised centre is near JPY 650-750m, with a band width of about plus or minus 20%. FY12/25 printed net income is flattered by about JPY 140m of non-recurring items. The FY12/26 forecast only just exceeds the FY12/24 peak operating profit on about 9% more sales.

内部研究类型：normalised_economics

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Band width is the key valuation parameter, and the margin of safety rests on the band's stability.

不确定性（原始记录）：This is research's own construction, since the company publishes no underlying-profit measure. Whether Mitsue lifts the centre is not observable yet.

研究原文：Valuation at the 6 November 2026 close: share price JPY 1,349; market capitalisation JPY 4.62bn on 3,427,200 issued shares (an issued-share basis that includes the 140,292 treasury shares); forecast PER 8.46x on FY12/26 forecast EPS of JPY 159.42; actual PBR 0.87x on FY12/25-end net assets per share of JPY 1,558.34; FY12/25 ROE 12.4% (flattered by special gains); forecast dividend yield 2.37% on JPY 32; EV/EBITDA 3.3x (EV JPY 3.21bn after net cash of JPY 1.42bn at 30 June 2026; EBITDA JPY 0.99bn = FY12/25 operating profit plus depreciation). The market capitalisation is below parent equity of JPY 5,362m, and the discount is read as pricing normalised earnings near the bottom of the band, with zero value for the Mitsui channel, Suminoe and any capital-policy change.

普通股东含义（原始记录）：Entry pays for asset cover and a 2.4% yield while waiting. Re-rating must come from prints and catalysts, not distribution growth.

不确定性（原始记录）：Multiples come from one thin-market print, with no analyst consensus. PBR, ROE and PER bases differ across sources and the derived values depend on those dates and denominators.

研究原文：Trading is extremely thin. Monthly volume runs 60,000-200,000 shares, and the 6 November 2026 session fell 4.8% on 17,300 shares with no disclosure. A margin long balance of 217,200 shares (about 6.6% of the roughly 3.29m free float, exceeding a typical month's volume) sits against zero shorts. The price can gap on no information and single prints carry little signal. Position sizing and entry patience matter more than timing precision.

不确定性（原始记录）：The margin balance is dated mid-July 2026.

研究原文：The environment segment is quietly off-plan. H1 FY12/26 intake was 10,748 tonnes, about 21,500 annualised, below the 2023 starting point of 22,000 and far below the 27,000-tonne target. Segment profit eased from JPY 126m to JPY 116m. Profit stability comes from mix and prices, not volume. Suminoe is the designated fix, so its opening date is a segment-level verification point.

普通股东含义（原始记录）：Discount any expectation of environment volume growth until the new yard converts.

不确定性（原始记录）：Why intake is flat is not disclosed. It could be capacity-limited or demand-limited.

研究原文：The Suminoe yard in Osaka (about 900 tsubo, acquired December 2025, opening targeted in FY2027) is the highest-certainty growth item. The Hanshin (Amagasaki) operation is at its capacity limit, so the yard converts existing unmet throughput in the densest demolition market into environment and metals volume without needing new demand. The FY12/25-27 investment stage depresses free cash flow, and returns must appear in FY12/27-28 segment profit.

研究原文：Per-project CO2 and material-balance data is a genuine differentiator in winning work. It is the service layer the Mitsui alliance is built around. It matches the GX League participation (2023), the RE Action commitment and the EcoVadis Silver credentials that large owners screen for, and it attaches to demolition mandates feeding all three segments. Regulation raises the fixed cost of being a credible venous operator, which taxes small rivals.

Remote-operation and AI-sorting themes (with Fukushima Daiichi method-study contracts in 2023) target labour shortage and hazardous work, not near-term revenue. The fleet gates the high-difficulty, high-margin project class and widens biddable scope.

研究原文：The Q3 FY12/26 tanshin is the nearest verification event. It was published on 14 November in each of 2023-2025, and the entry was blank at 9 November 2026, so a print is expected on 13-14 November 2026, immediately before the review date. It will show whether demolition margins held through nine months (the H1 level of roughly JPY 190m of half-year segment profit broadly held). Dated sequels follow: the FY12/26 annual results and next plan (February-March 2027), the Suminoe opening (FY2027), the first disclosed Mitsui-channel transactions, and any dividend or buyback reset. Each maps to one thesis variable, so the calendar is a verification schedule.

不确定性（原始记录）：The date is inferred from cadence. The Q3 print was unpublished when research was frozen, so the nine-month result is unknown here.

研究原文：Shareholder return in practice is the dividend alone. It is a flat JPY 32 year-end payment (about JPY 105m a year) held across FY12/24, FY12/25 and the FY12/26 forecast, with no interim dividend. The payout ratio was 20.3%, 17.6% and about 20.1% (dividend on equity about 2.1-2.3%). It moved neither on the FY12/25 profit fall nor on the H1 rebound. Buybacks were small (JPY 24.7m in FY12/24 and JPY 3.1m in FY12/25), so treasury shares stayed at 4.1% (140,292). A buyback round decided on 9 August 2024 was completed on 2 May 2025, and an earlier round was completed on 28 April 2023. A capital-cost response was disclosed on 14 December 2023, though its content was not re-read. Distribution debate is concentrated in the February results announcement.

内部研究类型：shareholder_return

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：A yield of about 2.4% is bond-like income. Returns must come from re-rating, and a step-up or buyback at scale would be a capital-policy signal.

不确定性（原始记录）：The board's hurdle for a rise is undisclosed. The open question text refers to a February 2023 capital-cost response, while the disclosure index dates it 14 December 2023, so the exact date is carried as inconsistent across source texts.

研究原文：The investment question is whether demolition's H1 FY12/26 margin repair is a durable cost-estimation capability (supervisors, machinery, in-house asbestos and heavy-lift) or merely the absence of last year's bad projects. If durable, a net-cash group earning a normalised ordinary profit of JPY 600-800m and paying a stable dividend is mispriced below book, with the Mitsui channel and Suminoe as unpriced options. The thesis fails in an observable way. Demolition margins would collapse again on new cost overruns in the Q3 or annual prints, supervisors would fall further, the next plan would cut the 2033 vision without a capital-policy offset, or receivables would absorb cash for a second year. In that case the repair was roll-off arithmetic, the band drops toward its bottom, and the below-book price is fair.

不确定性（原始记录）：Unresolved until the dated prints arrive.

研究原文：Protection against replication is a bundle, not a single barrier: site-specific waste and landfill permits (the purposes clause maps the permit perimeter), owned processing yards in a land-constrained region, super-large machinery, licensed supervisors and customer documentation that embeds the group in owners' compliance processes. Each element is replicable alone, and the value is the time a rival needs to assemble the chain in the same region. Competition is local and capability-tiered, so pricing power exists only in the top project-difficulty tier. The moat does nothing for the metals price exposure. A permit or compliance failure at one site would be disproportionately costly.

不确定性（原始记录）：Win rates, bid margins, permit renewal history and any regulatory action are undisclosed. No competitor data was obtained.

研究原文：Revenue quality differs by segment. Metals revenue is tonnage times market price (28,178 tonnes in H1 FY12/26, 88% through own plants versus 79% in FY12/25). Environment mixes contracted treatment with price-linked resource sales. Demolition is project-completion revenue with short backlog cover. Repeatability ranks environment highest, metals next and demolition lowest, while profit reliability ranks almost inversely. The decline in metals tonnage from 100,000 to 74,484 is partly deliberate, a shift to own-plant processing where margin is made, so tonnage alone misreads the segment.

研究原文：Demand is the sequential ageing of over JPY 3,000 trillion of construction stock reaching renewal age. This makes it a stock-turnover flow, so the plan treats supervisor capacity, not order demand, as the constraint.

研究原文：Durable business portrait: durable enterprise, conditional earnings stream｜The durable core is the assembly beneath the earnings, not the earnings, which oscillate in a JPY 545-824m ordinary-profit band. The assembly comprises site-specific permits, owned yards in a land-constrained region, super-large machinery, a licensed supervisor corps, and net cash with a 63.9% equity ratio and no post-IPO dilution. It has survived a scrap cycle, a profit halving and recovery, and a market-segment change, and is being thickened by Mitsue, Suminoe and the Mitsui framework. The fragilities are structural: earnings depend on cost estimation in a handful of large contracts, growth depends on a supervisor pipeline that shrank in the latest half, and control rests on one family with no disclosed succession. Durability is high for the enterprise and conditional for the earnings stream.

普通股东含义（原始记录）：The enterprise likely persists, but the shareholder return depends on whether earnings sit at the band's centre or bottom, which the next two prints discipline.
