SECカーボン株式会社（SEC Carbon, Ltd.）

研究原文：Completed Research upgrades the opening question. SEC Carbon is not simply a value trap versus a trough purchase: the share price is best read as a forecast about whether a debt-free balance sheet holding about JPY 45.7 billion of cash and securities (108% of market capitalisation) will be converted into per-share value, with the cathode-block replacement cycle acting as a second, partly independent option. The operative question is which of two dated processes (cathode volume with operating leverage in FY3/27 H2, or measurable capital-policy conversion under the 2030 framework) delivers first, and whether the carry (4.9% forecast yield) is adequate while waiting.

普通股东含义（原始记录）：Defines what the ordinary shareholder is actually underwriting: governance-and-cycle optionality funded by a yield, not a franchise recovery alone.

不确定性（原始记录）：The capital-conversion leg has no deadline and bloc intent is undisclosed; the cycle leg is tested only by prints after the review date.

研究原文：SEC Carbon, Ltd. (TSE Standard 5304, founded 1934, Amagasaki; Kyoto/Fukuchiyama and Okayama works) is an independent carbon-products maker with one reported segment. FY3/26 sales by product: graphitized cathode blocks for aluminium smelting 67.5%, graphite electrodes 17.9%, carbon specialties 11.5%, fine powder 3.1%. It sells qualified consumables into other industries' maintenance and operating calendars, about 73% overseas, with 57.8% of sales through one Sumitomo-group trading channel. About 270 staff produce roughly JPY 93 million of sales each: a capital- and process-intensive materials maker.

内部研究类型：COMPANY_IDENTITY_AND_BUSINESS_MODEL

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Two thirds of the investment case is one product's installed-base mathematics; the shareholder owns a claim on a two-cycle business (aluminium maintenance, steel operation).

不确定性（原始记录）：Product-level profit is not disclosed; model is described at revenue and group-margin level. Registered English name rests on Nikkei profile and EDINET header.

研究原文：The consolidated group is economically the parent plus small subsidiaries: parent-only sales are JPY 24,522 million (97.7% of consolidated) and minority interest is about JPY 14 million, so there is no hidden subsidiary profit pool. In FY3/26 the company acquired shares of Nippon Denkyoku, a small electrode-industry affiliate brought into the equity method; it lost JPY 16 million in FY3/26 and JPY 47 million in Q1 FY3/27, bought into the group in the same year the group's own electrode plant was written down.

内部研究类型：GROUP_PERIMETER_FACT

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Valuation can treat the listed entity as the operating enterprise; no SOTP uplift from subsidiaries and no minority leakage.

不确定性（原始记录）：Nippon Denkyoku's strategic purpose is not stated in the sources read; size is immaterial today.

研究原文：The earnings engine is the cathode-block replacement cycle. Cathode blocks (67.5% of sales) are consumed when aluminium smelter pots are relined and when smelters are built; demand is lumpy and project-sized, concentrated in the Middle East, Canada, Brazil and Asia. FY3/26 cathode sales fell 23.0% on slower smelter renewal and a customer inventory adjustment that took longer than expected, and group operating profit fell 41.3%. Q1 FY3/27 cathode sales rose 51.8%, with management saying the adjustment has turned toward resolution and some Middle East shipments slipped in from the prior quarter, so part of the rebound is shipment timing.

内部研究类型：CORE_EARNINGS_MECHANISM

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：The cycle verdict, and therefore operating earnings power, depends on this one product's volume slope into the second half of FY3/27.

不确定性（原始记录）：Order intake, backlog and smelter relining schedules are not disclosed; Q1 timing effects blur the true slope.

研究原文：Cathode revenue is recurring in kind: relining cannot be deferred indefinitely, so FY3/26's decline is partly postponed rather than lost revenue, a timing debt the cycle owes back. The 2024-2026 downturn was an inventory event layered on the relining calendar, so manufacturer volume fell more than end demand and a recovery would overshoot the same way. Revenue is nevertheless concentrated by product (67.5%) and channel (57.8%, down from 66.6% only because cathode volume fell), and is translated at a weak yen.

内部研究类型：REVENUE_QUALITY_JUDGEMENT

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Postponed revenue returns with interest if the installed smelter base keeps running, which supports a higher-than-trough valuation of the franchise.

不确定性（原始记录）：Smelter closures (as opposed to deferrals) would convert postponed revenue into lost revenue; no closure evidence in the record. Channel-level inventory is unobservable.

研究原文：The cathode franchise is protected by qualification incumbency: a failed cathode block costs a smelter a pot, so incumbent qualified suppliers keep the relining calendar and competition runs on proven life and delivery reliability rather than yen per tonne. Evidence is margin behaviour: gross margins of 31-36% and a 16% operating margin through a severe volume downturn. Know-how is embodied in process, plant and people. Competition is fought on different fields by line: qualification in cathode blocks, outright price in electrodes, which is why one line earned a write-down and the other did not. Erosion would arrive slowly, through a rival's multi-year qualification success or a smelting-technology change.

内部研究类型：MOAT_AND_COMPETITIVE_POSITION

内部来源标记：COVERAGE35

普通股东含义（原始记录）：The moat is what makes the trough survivable and the recovery option credible; it is capped because the same conservatism slows adoption of new products.

不确定性（原始记录）：No contract-level or independent share evidence was read; the moat is inferred from margin behaviour and failure-cost asymmetry. Evidence of share loss at a major relining programme would be the falsifier.

研究原文：Sumisho CRM, the Sumitomo Corporation group's carbon raw-materials company, carried JPY 14,514 million (57.8%) of FY3/26 sales (66.6% in FY3/25), and Sumitomo Corporation also holds 5.02% of the shares. The concentration is cyclical in degree but structural in kind: at a cathode peak, two thirds of revenue would again move through one counterparty's book. Share ownership aligns incentives but does not remove the exposure to a change in the Sumitomo group's carbon strategy, credit terms or channel economics.

内部研究类型：CONCENTRATION_RISK

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：A single-counterparty shock reaches most revenue at once; the same relationship also supports register stability.

不确定性（原始记录）：Commercial terms and the channel's margin share are undisclosed; resilience to a change in Sumitomo strategy is untestable from filings.

研究原文：Earnings have fallen two consecutive years from the FY3/24 peak. Ordinary profit went from about JPY 11.6 billion (FY3/24) to JPY 7,716 million (FY3/25) to JPY 5,683 million (FY3/26). FY3/26 sales were JPY 25,101 million (-19.5%), operating profit JPY 4,008 million (-41.3%) and the year closed with a net loss of JPY 74 million after a JPY 6,063 million impairment. Comprehensive income was JPY 5,831 million because securities valuation gains carried it.

内部研究类型：OBSERVED_PROFIT_TRAJECTORY

内部来源标记：OPEN_DISCOVERY

普通股东含义（原始记录）：Reported headline loss overstates operating weakness yet the underlying decline in operating profit is real and cycle-driven.

不确定性（原始记录）：Peak-year figures are derived from year-on-year rates in the FY3/25 filing.

研究原文：FY3/24 was the peak of the current cycle (derived sales about JPY 37.3 billion, operating profit about JPY 10.2 billion): two years of decline removed about a third of sales and half of ordinary profit. Ordinary profit swung by a factor of five trough-to-peak twice in a decade (FY3/19 JPY 17,109 million, FY3/21 JPY 3,493 million, FY3/24 JPY 11,555 million, FY3/26 JPY 5,683 million). Inside the trough the shape was sequential recovery: Q1 FY3/26 operating profit JPY 609 million (13.9% margin), Q2 JPY 970 million (16.4%), which is the basis for management calling Q1 FY3/26 the bottom. The cycle is split: cathode orders have turned while electrodes keep falling. By pattern (three to five years trough to peak) the position is early-recovery, but the last two years of decline show troughs here can last two full years.

内部研究类型：CYCLE_POSITION_JUDGEMENT

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Buying the trough is the historical trade; the historical risk is that the trough lasts longer than a holder expects.

不确定性（原始记录）：Whether Q2 FY3/27 cathode volume confirms the turn or shows Q1 as shipment timing; no industry-wide volume series was read.

研究原文：The FY3/26 margin decline was a volume event, not a cost event: gross margin fell from 35.6% to 31.2% as fixed production costs were absorbed over 19.5% less revenue, while SG&A was cut JPY 456 million to JPY 3,813 million, so operating margin fell from 21.9% to 16.0%. In Q1 FY3/27 gross margin recovered only to 32.1% despite the volume rebound because raw-material and fuel inflation (calcined coke, anthracite, pitch, electricity) offset the gain. Pass-through of price recovery will be visible only in gross margin.

内部研究类型：MARGIN_MECHANISM

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Operating leverage into a volume recovery is real; part of it is absorbed by commodity and energy costs the holder cannot hedge.

不确定性（原始记录）：Product-level margins and supplier contracts are undisclosed; commodity spread effect is not isolated.

研究原文：On 14 May 2026 the company booked a JPY 6,063 million impairment on the artificial graphite electrode manufacturing equipment because market-environment changes pushed its recoverable amount below book value. The write-down is specific: management is signalling which of its two historic franchises it no longer believes can carry its book value, and it is not the cathode franchise. Electrodes are structurally favoured by scrap-based electric-arc-furnace steelmaking but cyclically crushed because low-cost Chinese and Indian imports set the marginal price against weak crude steel output. Electrode sales were nearly flat in FY3/26 (-0.9%) as a price/mix defence the write-down says cannot continue at book values; Q1 FY3/27 electrode sales fell 18.9%.

内部研究类型：ASSET_IMPAIRMENT_AND_FRANCHISE_ADMISSION

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Management has conceded part of the asset base cannot earn its carrying value; the sub-franchise is exposed to import pricing the company cannot influence.

不确定性（原始记录）：The electrode endgame (capacity cut, grade retreat or continued operation) is not stated; import price trends and overseas capacity exits are unobserved.

研究原文：JPY 6,063 million of book value removed from the electrode equipment mechanically lowers future depreciation on that line, so smaller reported losses or small profits from electrodes are expected arithmetic. The write-down changes the cost denominator, not the market; only price or volume evidence should be read as recovery.

内部研究类型：ACCOUNTING_ARTEFACT_QUALIFIER

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Prevents mistaking accounting relief for operating recovery in the electrode line.

不确定性（原始记录）：Depreciation saving amount is not disclosed by line.

研究原文：The headline loss is an accounting admission, not a cash event. The JPY 6,063 million impairment turned a JPY 4,008 million operating profit into a JPY 74 million net loss, yet FY3/26 operating cash flow rose 71% to JPY 7,766 million because the impairment and JPY 2,048 million of depreciation are non-cash and cash taxes fell to JPY 1,073 million. Receivables of about JPY 9.4 billion and inventories of JPY 18.3 billion unwind when volume falls, so operating cash flow is countercyclical: it undershot ordinary profit in the FY3/25 upcycle (JPY 4,548 million versus JPY 7,716 million) and overshot it in the FY3/26 downcycle (JPY 7,766 million versus JPY 5,683 million). The company got cash-richer in its loss year; Q1 FY3/27 shows the reverse starting, with every inventory layer stocked while receivables fell JPY 2,388 million.

内部研究类型：CASH_VS_ACCOUNTING_DIVERGENCE

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：The shareholder's company is richer in cash after its worst earnings year than before it, and cash will deteriorate as earnings recover; a headline reader can misread both signals.

不确定性（原始记录）：Whether FY3/27 recovery re-absorbs cash at the FY3/25 rate; no quarterly cash-flow statements for Q1.

研究原文：Tokai Carbon (5301), the larger listed peer, printed Q3 FY12/26 cumulative ordinary profit up 27.0% on 5 November 2026, driven by carbon black and fine carbon. The comparison removes carbon industry weakness as an excuse: SEC Carbon's weakness is specific to electrodes and the cathode relining calendar, both company-level exposures, though product mixes differ.

内部研究类型：EXTERNAL_COUNTER_EVIDENCE

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Attributes the earnings drop to company-specific exposure rather than industry weather, which both raises the credit for a cathode turn and removes macro cover for misses.

不确定性（原始记录）：Peer mix is broader (carbon black, industrial furnaces); comparability is partial and no independent share series was read.

研究原文：At 31 March 2026 total assets were JPY 87,016 million, net assets JPY 77,628 million, equity ratio 89.2%, no borrowings, and interest-bearing debt to operating cash flow 0.0 years for five years. Cash and deposits of JPY 17,533 million plus investment securities of JPY 27,813 million (valuation reserve JPY 14,924 million) are 52% of total assets, against net tangible fixed assets of only JPY 13,316 million. At the Q1 FY3/27 balance sheet, cash plus securities of JPY 45,668 million were 108% of the 6 November market capitalisation of JPY 42.26 billion: on market pricing the operating business, plant, land and inventory are free. The same structure is why forecast ROE is 3.9% and PBR 0.52-0.53: downside protection and ROE dilution are one fact. The equity ratio dipped to 83.0% in FY3/24 during heavy investment and has since been restored by retained earnings and valuation gains, not new equity.

内部研究类型：BALANCE_SHEET_STRUCTURE

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Guarantees survival through any customer-imposed cycle and caps returns with the same yen.

不确定性（原始记录）：Securities are marked, land and plant are at historical cost; portfolio name-level composition and cost base (hence tax and relationship cost of unwinding) sit in securities-report schedules; Q1 securities valuation partly reflects relationship holdings that may not be freely saleable. Treasury shares are 4.1% of issued shares, so the market-capitalisation denominator includes treasury shares.

研究原文：Land for the Amagasaki head office and the Kyoto (Fukuchiyama) and Okayama works is carried at JPY 1,262 million at historical cost, unchanged across balance sheets read, with no appraisal disclosed; the fixed-asset base is stated far below replacement cost. Machinery gross of JPY 48,159 million is 90% depreciated.

内部研究类型：UNMARKED_ASSET

内部来源标记：COVERAGE35

普通股东含义（原始记录）：A hidden reserve of unknown size and a reminder that earnings power, not the asset register, must justify equity value; it is also not distributable without disrupting production.

不确定性（原始记录）：Land market value is unknown and not estimated.

研究原文：The register and the portfolio mirror each other: Nippon Carbon (listed peer) holds 4.06%, Yamato Kogyo (steelmaker) 2.38%, banks and trading houses throughout, while the company's own JPY 27.8 billion securities portfolio is more than half unrealised gain on long-held relationship shares. The web is the register's shock absorber and its discount engine at once: it prevents hostile pressure for change and guarantees the float cannot price one in. The Q1 FY3/27 sale (JPY 527 million gain) is the first evidence in this research of the portfolio being actively trimmed.

内部研究类型：CROSS_HOLDING_WEB

普通股东含义（原始记录）：Stabilises operations and the register but supports the discount; unwinding would be the clearest sign capital policy is real.

不确定性（原始记录）：Name-level composition and cost base are unread; which holdings are reciprocal commitments is unknown.

研究原文：The register is the discount. Otani Steel Corporation holds 19.85% and is the subject of annual controlling-shareholder filings, with Otani-family entities filing alongside; Mitsubishi Corporation holds 9.78% and Sumitomo Corporation 5.02% (the latter also intermediates 58% of sales); Master Trust 4.89%, Nippon Carbon 4.06%, MUFG Bank 2.66%, Yamato Kogyo 2.38%, Nippon Steel Engineering 2.09%; 4,922 shareholders. The effective float is thin: five-day average volume to 6 November was about 59,000 shares a day, margin buying was 20.96 times margin selling in the 17 July snapshot, and a 6 November session on 134,900 shares (+75% on trend) moved the price 4.18% without earnings news. Stability cuts both ways: no internal mechanism closes a discount and no forced seller exists.

内部研究类型：OWNERSHIP_AND_FLOAT_STRUCTURE

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Minorities are junior partners in someone else's ecosystem: protected from disruption, excluded from forcing change; entry and exit both run through a thin float so position size is a binding constraint.

不确定性（原始记录）：Bloc intentions are undisclosed; holdings are as of 31 March 2026 and intra-year changes are visible only through large-holding reports. Margin snapshot is dated 17 July.

研究原文：The valuation discount is a capital-governance discount, not a franchise or solvency discount. With a 19.85% controlling shareholder from the founding family's steel company, about a tenth of the register in two trading houses, a sales channel concentrated in one Sumitomo-group company, and about JPY 45 billion of financial assets compounding at deposit-and-dividend yields, the market prices the probability that the pile is never converted into per-share value. The market has never in FY3/22-FY3/26 valued the company above about three fifths of book equity (market-value equity ratio 38.1% to 60.9%). The market pays trough operating earnings at a full multiple while valuing the balance sheet at half, a combination that only makes sense if the discount is expected to be permanent.

内部研究类型：VALUATION_MECHANISM

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：The holder is paid in yield and discount to wait for governance or cycle change; re-rating is led by register events or prints, not abstract multiple expansion.

不确定性（原始记录）：Opposing evidence: the 2026 buyback and first securities sale show the bloc is unblocked; the discount may narrow without a declared programme. Timing is undeterminable.

研究原文：Valuation at the 6 November 2026 close (review date 9 November 2026): share price JPY 2,042 (-4.18% on the day); market capitalisation JPY 42.26 billion on 20,694,340 issued shares; forecast PER 13.6x on FY3/27 company-forecast EPS of JPY 149.64 (unchanged at Q1); actual PBR 0.53x on FY3/26 net assets per share of JPY 3,871.46 (IRBANK shows 0.52x); FY3/26 ROE -0.1% as reported (net-loss year); forecast dividend yield 4.90% on JPY 100; EV/EBITDA 4.1x (EV JPY 24.65 billion after net cash of JPY 17.60 billion at 30 June 2026; EBITDA JPY 6.06 billion = FY3/26 operating profit JPY 4,008 million plus depreciation JPY 2,048 million). About 14 times FY3/27 forecast net income, but under 6 times the five-year average ordinary profit (about JPY 7,269 million, pre-tax): the gap is the price of cyclicality. Forecast ROE is 3.87%.

内部研究类型：VALUATION_SNAPSHOT

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Provides the point-in-time pricing frame; trough earnings look full while assets look cheap.

不确定性（原始记录）：Mixed bases: EV uses a 30 June 2026 net cash figure with FY3/26 EBITDA; PER uses company forecast; market capitalisation uses issued shares including treasury shares (4.1% of issued at Q1, possibly higher after the buyback completed in September); ex-treasury capitalisation would be modestly lower. Net cash includes relationship securities excluded from the EV cash figure. Price is the 6 November close; later November price action is not captured.

研究原文：Five-year ordinary profit (FY3/22-FY3/26: JPY 3,779 / 7,610 / 11,555 / 7,716 / 5,683 million) averages about JPY 7,269 million; the three-year mean is about JPY 8,318 million. Because the financial-income layer (JPY 1.3-1.7 billion a year of dividends, subsidies and FX) is embedded, operating-level mid-cycle pre-tax earning power sits nearer JPY 5.5-6.0 billion, against which the market capitalisation is about 7 times. Earning power has been durable in range (JPY 3.5-17 billion of ordinary profit across a decade with no loss year at the ordinary level), but the five-year window contains one supercycle descent and one trough, so its mean is a fair mid-cycle estimate only if FY3/19-style peaks and FY3/21-style troughs remain equally possible.

内部研究类型：NORMALIZED_EARNINGS_JUDGEMENT

内部来源标记：COVERAGE35

普通股东含义（原始记录）：On normalised numbers the shares are cheap but not absurd; on trough numbers they are full: the decision is the cycle judgement plus the governance option.

不确定性（原始记录）：Pre-FY3/25 operating profit history is not fully disclosed, so the operating-level range is derived from ordinary profit and FY3/26 non-operating detail, not a precise series.

研究原文：Reported ordinary profit overstates the operating franchise in the trough. FY3/26 non-operating income of JPY 1,716 million (dividends JPY 845 million, subsidies JPY 445 million against JPY 26 million a year earlier, FX gains JPY 189 million, interest JPY 131 million) lifts ordinary profit 42% above operating profit. About a third of ordinary profit is not from selling carbon products, so the carbon businesses earned closer to JPY 4.0-4.4 billion of recurring operating-level profit. Three layers with three durabilities sit in one number: cathode operating margin (cyclical, real), electrode margin (impaired, contested) and financial income (stable, unrelated to operations). Any normalisation that starts from ordinary profit inherits the flattery.

内部研究类型：PROFIT_QUALITY_STRUCTURE

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：The same reported ordinary profit is worth less per yen than in FY3/24 because its mix shifted toward financial income; capitalise the layers separately.

不确定性（原始记录）：Subsidy recurrence is unexplained in the sources read; the equity-method loss is small.

研究原文：Four disclosed items sit between operating reality and reported profit: the JPY 6,063 million electrode impairment (an economic admission, not cosmetic); a JPY 1,852 million deferred-tax adjustment gain generated by the impairment (net tax credit JPY 349 million on a JPY 423 million pre-tax loss, non-repeatable, flattering FY3/26's bottom line versus FY3/27's normal tax charge on JPY 3,000 million); subsidy income of JPY 445 million inside ordinary profit; and a partial numerical correction to the FY3/26 tanshin published 19 June 2026. None signals concealment; accounting reads as conservative-with-explanations.

内部研究类型：ACCOUNTING_ITEMS_REGISTER

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Adjusted for the four items the company is cleaner and less dramatic than headlines show in both directions; deferred tax assets are not cash.

不确定性（原始记录）：The correction notice figures and the tax and subsidy notes were not read line by line; the securities report notes (filed 19 June 2026) are the reference.

研究原文：FY3/27 guidance (14 May 2026) is built as a trough: sales JPY 26,500 million (+5.6%), operating profit JPY 3,400 million (-15.2%, a third straight annual decline), ordinary profit JPY 4,400 million, net income JPY 3,000 million, EPS JPY 149.64, at USD/JPY 155 with the Middle East explicitly excluded. The interim plan (sales JPY 10,600 million, operating profit JPY 1,100 million, net income JPY 1,300 million) was held at Q1. Subtracting Q1 actuals leaves an implied Q2 of sales about JPY 5,057 million and operating profit only about JPY 336 million (6.6% margin). Q1 delivered 52% of planned sales, 69% of operating profit, 74% of ordinary profit and 94% of net income, but the last only because of a JPY 527 million securities-sale gain. The interim verdict therefore turns on second-quarter cathode volume, the one number one-offs cannot fake; the plan embeds either deliberate conservatism or a genuinely weak expected Q2.

内部研究类型：GUIDANCE_CONSTRUCTION

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：A 'guidance held' headline can hide either a volume beat or a volume miss; one quarter and one product line decide whether guidance credibility is rebuilt.

不确定性（原始记录）：H1 results had not been published at the review date; implied Q2 is arithmetic on an unchanged plan, not company guidance.

研究原文：Expectations are set by the company itself: no sell-side chorus was read, so guidance credibility is the expectations mechanism and the April plan break has already taxed it once. The bar is low, one-off flattery is disclosed and the volume line cannot be dressed up, so the asymmetry favours the sceptic about headlines. Traded multiples (about 13.5-13.6 times forecast) price guidance as roughly honest.

普通股东含义（原始记录）：A print-day move depends less on the headline than on cathode volume versus the implied weak Q2.

不确定性（原始记录）：No analyst consensus series was read; whether 'within the expected range' language survives the H1 print is unknown.

研究原文：Capacity is being rotated. Electrode assets were written down by JPY 6,063 million in the same year a large facility completed (construction in progress fell from JPY 8,505 million to JPY 1,552 million, machinery gross up JPY 2,956 million, buildings up JPY 1,090 million) and a new build cycle began (JPY 2,674 million by Q1 FY3/27, +JPY 1,121 million in the quarter). Depreciation stepped up from JPY 1,304 million to JPY 2,048 million and reached JPY 430 million in Q1 alone. Capital is being re-pointed away from commodity electrodes, but the filings do not say toward what, at what return. The higher fixed-cost floor arrives ahead of the recovery: operating leverage will be sharp if cathode volume delivers and the trough gets more expensive to sit in if it disappoints.

内部研究类型：CAPITAL_ALLOCATION_ROTATION

普通股东含义（原始记录）：The shareholder has already paid for the next decade's capacity; what remains is utilisation risk and whether it earns above the cost of capital.

不确定性（原始记录）：Product, purpose and budget of the completed facility and of the new construction are undisclosed; capex return and cost of capital are not stated.

研究原文：Distribution policy is the higher of JPY 100 per share or a 30% consolidated payout. JPY 2,004 million was paid in both FY3/25 and FY3/26 (through a loss year, formula unchanged), with JPY 100 forecast for FY3/27 (interim 50, final 50), a 66.8% payout on forecast EPS of JPY 149.64: the floor clause, not the ratio clause, does the work. Against equity it is a dividend-on-equity floor of about 2.6% (FY3/26) to 2.8% (FY3/25); at the November price it is a 4.9% yield. The payout ratio absorbs earnings volatility while the dividend and therefore the yield floor stay stable.

研究原文：Capital conversion has begun at walking pace. A buyback authorised on 14 May 2026, the day results were announced, bought 207,500 shares for JPY 529 million in Q1 (average about JPY 2,549) and was completed on 16 September 2026; off-auction buybacks also occurred in June and September 2024. Treasury shares rose from 646,695 to 854,195 (4.1% of issued); issuance has been frozen at 20,694,340 and the weighted-average count fell from 20,135,249 to 19,975,434. Retiring shares near JPY 2,549 against book value per share of JPY 3,871 transfers value to remaining holders, but the pace of about JPY 0.5-1.0 billion a year moves a JPY 77.6 billion equity base by about 1% a year. In Q1 FY3/27 net assets eased JPY 52 million despite JPY 1,224 million of net income: profits are returned about as fast as earned, and the pile does not shrink. The first securities sale (JPY 527 million gain) accompanied it. No treasury-share cancellation appears.

The 12% FY3/31 target cannot be reached by the profit leg alone on any guided trajectory: on unchanged equity of about JPY 77.6 billion it needs roughly JPY 9.3 billion of net income, three times the FY3/27 forecast. It is therefore silently a joint promise about earnings recovery and equity shrinkage, and only the first half has numbers attached. The abandoned plan had staged ROE at 8% for FY3/30, implying management expected the profit leg to do most of the work; the new policy adds capital-policy advancement as a pillar without quantifying the split.

内部研究类型：CAPITAL_EFFICIENCY_ARITHMETIC

内部来源标记：COVERAGE35

普通股东含义（原始记录）：Without a denominator policy ROE mean-reverts to mid-single digits; with one the target is arithmetic, not hope. Current return is dividend yield plus slow book compounding.

不确定性（原始记录）：No company cost-of-capital estimate or quantified capital-efficiency milestone was read.

研究原文：On 10 April 2026 the company abolished its ninth three-year mid-term plan rather than miss it quietly and replaced it with the '2030 Make Real' policy: FY3/31 targets of sales JPY 54,000 million, operating profit JPY 10,000 million and ROE 12%, via strengthening the growth strategy and advancing capital policy. The abandoned plan targeted FY3/27 sales of JPY 44,000 million and operating profit of JPY 8,000 million, against FY3/27 guidance a month later of JPY 26,500 million and JPY 3,400 million (40% and 58% short). Even the plan document's FY3/26 outlook (sales JPY 29,200 million) overshot the actual result (JPY 25,101 million) by 14% five weeks before printing, exposing a near-term optimism bias. The FY3/31 sales target is more than double FY3/26 in a mature, slow-growth market, so it arithmetically requires share gain, a supercycle, or both; it should be treated as an aspiration to be re-earned through prints, not a path.

内部研究类型：PLAN_CREDIBILITY_JUDGEMENT

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：Credibility has to be rebuilt print by print starting with the H1 FY3/27 tanshin; candid abolition is mildly positive governance behaviour but removes any quantified roadmap.

不确定性（原始记录）：Which growth sources management names and funds is unknown.

研究原文：The 2026 governance calendar was active: mid-term plan abolished 10 April, controlling-shareholder filing 24 April, FY3/26 results with impairment, buyback authorisation and dividend decision on 14 May, representative-director change announced 8 June ahead of the 26 June AGM, a partial numerical correction to the tanshin on 19 June, monthly buyback notices, and completion on 16 September. The board is managing toward credibility inside a perimeter the controlling bloc defines, conceding failures in print rather than promoting. No specific agenda for the leadership change is stated in any source read.

不确定性（原始记录）：Board composition and the governance report were not re-read; the new leadership's first full-year print is outstanding.

研究原文：Historically every turn in this name was delivered by the product cycle (FY3/19 supercycle and give-back; FY3/24 second peak). 2026 is the first year in which management and register actions (plan abolition, impairment, buyback, securities sale, leadership change) outnumber cycle events. Reading A: a regime change toward capital and governance, meaning today's price is a trough multiple on a re-rating asset. Reading B: a cluster of one-offs, meaning a fair price on a cyclical. The H1 and full-year prints and capital-policy follow-through discriminate between them.

不确定性（原始记录）：Unresolved by design; follow-through in FY3/27-FY3/28 disclosure, more instruments or silence, is required.

研究原文：The trough reading fails if the cathode inventory adjustment relapses or smelters defer relining again, a risk management itself flags alongside cheap electrode imports. Inventory is the relapse sensor: work in process is 47% of annual sales (JPY 11,766 million) and total inventories 73% (JPY 18,252 million), so renewed destocking would show up first as inventory build and margin compression, and the FY3/26 pattern, a recovery that took longer than expected, is the documented precedent. Management's outlook still describes every product line as facing a harsh environment.

内部研究类型：PRINCIPAL_RISK

内部来源标记：OPEN_DISCOVERY / COVERAGE35

普通股东含义（原始记录）：A relapse would compound the cost of the new fixed-cost floor and delay both Thesis legs.

不确定性（原始记录）：Order intake and relining schedules are not disclosed; inventory book value is not treated as liquid downside value (no evidence on saleability or haircut).

研究原文：About 73% of sales (JPY 18,356 million) are exported and the forecast is struck at USD/JPY 155. FY3/26 booked JPY 189 million of FX gains, and ordinary profit beat forecast on a weaker yen and larger dividends; Q1 FY3/27 credits yen weakness for part of the recovery. A yen reversal is the fastest route to a guidance miss and would expose how deep the volume trough still is. No hedge policy is described. Management excluded the Middle East situation from guidance as unquantifiable, and the largest regional sales block (Asia and Middle East, JPY 7,631 million) contains the unmeasured exposure. Policy transmission is second order: decarbonisation supports customers' processes and taxes the company's own energy-intensive graphitisation.

研究原文：The H1 FY3/27 interim tanshin, expected around 12-13 November 2026 on the prior-year pattern (13 November in 2024 and 2025, with a same-day revision notice in 2025) and not published at the review date, is the nearest verdict: whether guidance survives a quarter the plan built to be weak, and whether cathode volume confirms the Q1 turn. The FY3/27 full-year print and year-end dividend decision (May 2027) and the securities-report register (June 2027) follow.

不确定性（原始记录）：Date inferred from pattern; outcome not knowable at the cut-off.

研究原文：The capital-policy pillar becomes a catalyst only when it acquires numbers: a treasury cancellation, a quantified securities-unwind programme, a raised dividend floor, or a buyback sized in billions rather than hundreds of millions. The 2026 record (completed buyback, first portfolio sale, ROE pledge) shows the instruments are unblocked, so the next disclosure on any of them reprices the discount directly. None of the three 2026 facts yet moves the equity base materially, which is the gap the valuation prices.

普通股东含义（原始记录）：The most direct path from the financial pile to per-share value.

不确定性（原始记录）：No timetable, no bloc intent statement.

研究原文：The shares price a permanent mid-cycle discount on a debt-free balance sheet whose financial assets alone exceed the market capitalisation. The position re-rates only if one of two dated processes delivers: the cathode-block replacement cycle printing rising volume and operating leverage through FY3/27's second half, or the capital-policy pillar of the 2030 framework converting the securities-and-cash pile into buybacks, cancellations or distributions at a pace minorities can measure. Absent both, the JPY 100 dividend floor and slow buybacks are carry, not catalyst. The thesis is a conjunction (trough and conversion option), so it degrades gracefully: each falsifier removes one leg and reprices the other, except a cathode-asset impairment, which attacks the franchise itself.

内部研究类型：INVESTMENT_THESIS

内部来源标记：OPEN_DISCOVERY

普通股东含义（原始记录）：Instruction set: hold while falsifiers stay unprinted and the carry pays; re-underwrite on the first falsifier; exit on the franchise-level one.

不确定性（原始记录）：Counter-evidence: the 2026 sequence may be a cluster of one-offs rather than a regime change; capital conversion has no deadline so discipline must come from the dated falsifiers, not patience alone.

研究原文：Dated, observable falsifiers: a guidance cut with cathode volume falling at H1; a second impairment, or any impairment of cathode assets (franchise-level); the dividend formula amended downward; the securities pile untouched and buybacks stopped through FY3/28; and evidence of share loss at a major relining programme. Falsification is defined on company disclosures and prints, not on price levels: price can falsify timing but not the thesis.

Each layer (asset coverage, income floor, register stability) fails independently. The realistic downside is duration, years of about 5% carry while the discount persists, an opportunity-cost loss rather than a capital loss. Three events would break it: a bloc sale, a formula repeal, or a catastrophic capex error. Asset coverage grows by retained earnings each year the formula holds.

不确定性（原始记录）：Forced-liquidation value and land market value are not estimated; securities are partly relationship holdings that may be hard to monetise without cost.

研究原文：The durable core is a qualified consumable franchise wrapped in an over-capitalised shell. The franchise (SK-B cathode blocks qualified into the world's aluminium smelters, produced by a 92-year-old graphitisation process) survived the 2008 crisis, the electrode supercycle's rise and collapse and a two-year customer inventory strike, earning a 16% operating margin in its worst recent year. The shell (89% equity, no debt, JPY 45 billion of financial assets) lets the franchise wait out any customer cycle. Fragilities are equally structural: two thirds of revenue rides one product's maintenance calendar; the second franchise is formally impaired; three quarters of sales are exported through one channel; and the controlling register has not yet converted the shell into per-share value at a measurable pace. Durability is total for the enterprise and conditional for the share.

Normalised operating-level earning power is nearer JPY 5.5-6.0 billion pre-tax than the ordinary-profit mean; the discount is a governance forecast with the cycle as a second option.

研究原文：Research Dividend produced by the current FIRST_COMPLETE Review｜Non-obvious gains from deeper research: loss year as a cash-richer year; ordinary profit flattered by a financial layer; guidance whose profit is front-loaded into a one-off-assisted Q1; financial assets exceeding the entire market value; an ROE target that silently needs equity shrinkage; post-impairment arithmetic that can mimic recovery; peer divergence that removes industry excuses. No prior Review exists, so all are current-Review discoveries.

研究原文：Carried Research Debt and next-evidence boundaries｜Ten open questions remain; none has a reasonable current public path (H1 results are a future disclosure after the information set; others depend on company disclosure not yet issued). They condition confidence in cycle timing, capex return and capital-policy pace rather than reopening Research.
