The diluted share count moved ×1.43 into 2020 — shares issued, not a split the totals corroborate — and the per-share figures carry the counts as filed.

Share counts before 2024 are restated ×5 for a stock split, so per-share figures sit on one basis.

Net income is the accountant's number; owner earnings is the cash an owner could take out. The walk between them, off the cash-flow statement, and whether the gap is widening or holding.

In fiscal 2026 the business earned ¥296.5B of owner earnings, the operating cash left after the ¥96.0B it takes just to hold its position. It put ¥58.9B more into growth; free cash flow, after that spending, was ¥237.6B.

Owner earnings is the cash an owner could pull out without starving the business: operating cash less the maintenance capital it must spend to hold its position (here about ¥96.0B, roughly its depreciation, the rate its assets wear out). The other ¥58.9B of its capital spending is growth it chose, not upkeep it owed; charged only with the maintenance it must do, the business earns well more than the year's free cash flow shows.

Maintenance capex is estimated as depreciation where a growing business invests above it; free cash flow is the figure the scorecard's free-cash margin reads.

Owner’s Scorecard

FY2026 Annual securities report · source on EDINET →

Will it survive?

  • Comfortable
    Operating income ¥212.2B ÷ interest expense ¥18.1B
    What this means

    Operating profit covers interest with the kind of margin Graham wanted for a defensive holding. Necessary, not sufficient, it says solvent, not cheap.

  • How heavy is the debt, net of cash? ¥1.21T · 5.7× operating profit
    Heavy net debt
    Cash ¥157.1B − debt ¥1.36T
    What this means

    Netting ¥157.1B of cash and short-term investments against ¥1.36T of debt leaves ¥1.21T owed, about 5.7× a year's operating profit (6.4× on the gross debt, before the cash). Net debt is the leverage figure that matters: the cash is already set against the debt. Strategic or illiquid investments aren't counted here.

  • Long (60+ days)
    DSO 38 + DIO 68 − DPO 42 days
    What this means

    Days cash is tied up between paying suppliers and collecting from customers. Lower is better; a long cycle means growth itself eats cash.

Is it a good business?

  • Below average through the cycle
    10-yr median, range -0%–13%; 6% latest = NOPAT ¥167.6B ÷ invested capital ¥2.83T
    Industry peers: median 10%
    What this means

    The rate the business earns on the money tied up in it, Buffett's north star, because over time a stock tracks the ROIC beneath it. Above ~15% sustained hints at a moat; a return below the cost of capital (~8%) erodes value as a business grows rather than building it — the test Buffett weighs most. The headline is the median of the last 10 years (it ran 6% most recently), so one peak or trough year doesn't set the verdict. Asset-light businesses (R&D expensed, little capital) read artificially high, pair this with Owner Earnings.

  • Thin, recently turned positive
    latest ¥296.5B = operating cash ¥392.4B − maintenance capex ¥96.0B; positive each of the last 3 years, after an earlier loss stretch (10-yr median 1%)
    Industry peers: median 2%
    What this means

    What an owner could take out without starving the business: operating cash less the maintenance capital it must spend to hold its position — Buffett's owner earnings. That's 4% of revenue this year, a 1% median across 10 years.

  • Cash-backed
    Cash from ops ¥392.4B ÷ net income ¥171.9B
    What this means

    How much of reported profit showed up as operating cash. Above 1× is reassuring; well below suggests earnings lean on accruals. One year is noisy, growth and working-capital swings distort it, and this is operating cash, not free cash. Watch the multi-year trend.

How is the cash used?

  • Reinvests most of it
    Dividends + buybacks ¥46.5B ÷ Owner Earnings ¥296.5B — this fiscal year
    What this means

    Of ¥296.5B Owner Earnings, ¥46.5B (16%) went back to shareholders, ¥44.2B dividends, ¥2.3B buybacks. Returning most of it is the mark of a mature business with little left to reinvest at a high return; reinvesting most could mean a long runway, or empire-building. The split doesn't say which; the return earned on it (see ROIC) does. This year's proportion is 16%; across the record (2017–2026) it is 65%, the capital-allocation section below.

  • Investing or harvesting? 1.61×
    Expanding
    Capex ¥154.9B ÷ depreciation ¥96.0B
    What this means

    Descriptive, not a grade. Above ~1× means investing faster than assets wear out (growth, or, sustained for years, today's earnings carrying less depreciation than tomorrow's will). Below means spending less than it's wearing out (efficiency, or a melting asset base). The ratio won't tell you which; the filings will.

Durability & moat, 2017–2026

Whether the record’s returns held, and what the capital reinvested earned.

  • Profitable years 9 of 10
    What this means

    Lost money in 1 year(s), look at what happened there before trusting the average.

  • Return on capital ≥ 15% 0 of 10 yrs
    What this means

    A moat shows up as a high return on invested capital that holds year after year, not one good vintage.

  • Operating margin 5% → 3% (3-yr avg ends)
    What this means

    Through the cycle the operating margin slipped — about 5% early to 3% lately, median 3% — competition or costs are biting in.

  • Reinvestment, incremental ROIC 5%
    What this means

    Reinvested capital came back at only a modest incremental return — near the cost of capital, where extra growth adds little per dollar. The record shows whether it is a soft stretch or a thinning moat.

  • Owner earnings growth +25%/yr
    What this means

    Owner earnings grew about 25% a year over the record.

  • Worst year 2020 · −0.1% op. margin
    What this means

    Operations went underwater in 2020, understand why before trusting the good years.

  • Dividend record rising
    What this means

    Paid and raised the dividend across the record, the continuity Graham prized.

All figures as filed; the source filing is linked above.

How the cash was used, 2017–2026

Over the record, the business generated ¥1.84T of operating cash; how management split it reads as a balanced allocator, splitting cash between the business, owners, and the balance sheet.

  • Reinvested¥908.1B · 49%
  • Dividends¥331.4B · 18%
  • Buybacks¥307.2B · 17%
  • Retained (debt / cash)¥292.2B · 16%
  • Returned to owners¥638.6B

    65% of the owner earnings the business produced over the span, ¥331.4B as dividends and ¥307.2B as buybacks.

  • Source of fundingOperating cash

    Operating cash covered reinvestment and returns; over the span debt rose ¥311.6B and cash and short-term investments rose ¥67.0B.

  • Average price paid for buybacks

    Buybacks ran ¥307.2B over the span, but the filings don't tag the share count needed to deduce the average price paid.

  • Net change in share count61.1%

    The diluted count rose from 800M to 1289M: issuance (stock pay, deals) outran any buybacks, so owners were diluted on net.

  • Dividend record¥34.30/sh

    Paid in 10 of the years on record, the per-share dividend growing about 15% a year. It was cut at least once along the way.

  • Return on what it retained37%

    Of the earnings it kept rather than paid out (¥742.9B over the span), annual owner earnings (first three years vs last three) grew ¥275.9B, so each retained ¥1 added about 0.37 of yearly owner earnings. Buffett's test, run on owner earnings instead of market value.

Buybacks are gross of stock issued to staff; the share-count line above is the net of that, the figure that decides whether owners gained. The average price paid blends a year of purchases (and any accelerated repurchase), so it is close, not exact. The record of where the cash went and on what terms.

The price

What a price would have to assume, set against the record above.

What the price implies

reverse-DCF

Type today's close and see the owner-earnings growth you'd have to believe to justify it, beside what Idemitsu Kosan has delivered.

Idemitsu Kosan’s latest year runs above its own through-cycle margin — the reported figure may flatter a peak. So the tool opens on the through-cycle base, Graham’s averaging cutting both ways; clear the toggle below to read the latest year exactly as reported.

¥

Through the cycle, Idemitsu Kosan earns about ¥112.4B on its 1.4% median owner-earnings margin. This year’s 3.7% margin runs above that; the reported figure may flatter a peak you'd be paying on. Normalize, below, values the price on that through-cycle figure rather than the latest year. It comes pre-checked here for that reason, the same rule that already normalizes a trough; clear it to price the year as filed.

The base opens on the through-cycle figure (the latest year sits above the record’s own median, and Graham’s averaging cuts both ways); clear Normalize to use the year as filed. Net of stock comp treats option pay as the expense it is. Capex (¥154.9B) runs well above depreciation (¥96.0B), so this is a build-out; Steady-state swaps total capex for maintenance (≈ depreciation), lifting the base to about ¥296.5B, the cash it would throw off if it stopped expanding.
