Will it survive?

• Can it pay its interest? —
  No meaningful interest burden
  Little or no interest expense reported
  What this means

  Little or no interest expense reported, the business isn't leaning on lenders to operate.

• How heavy is the debt, net of cash? +CN¥812M
  Net cash
  Cash CN¥807M + ST investments CN¥83M − debt CN¥77M
  What this means

  Cash and short-term investments exceed every dollar of debt by CN¥812M, on net the company owes nothing, and can act from strength when others can't. Net debt is the leverage figure that matters: the cash is already set against the debt. Strategic or illiquid investments aren't counted here.

• How long is cash tied up? -42d
  Negative, funded by others
  DSO 36 + DIO 26 − DPO 104 days
  What this means

  Days cash is tied up between paying suppliers and collecting from customers. A negative cycle is a quiet moat: suppliers and customers fund the operation (Buffett's “float”), the company grows on other people's money.

Is it a good business?

• Return on invested capital 7%
  Below average through the cycle
  4-yr median, range 4%–23%; 15% latest = NOPAT CN¥118M ÷ invested capital CN¥797M
  Industry peers: median 14%
  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 4 years (it ran 15% 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.

• Owner-earnings margin 5%
  Thin through the cycle
  10-yr median margin, range -18%–32%; latest CN¥113M = operating cash CN¥155M − maintenance capex CN¥41M
  Industry peers: median 12%
  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 5% of revenue this year, a 5% median across 10 years.

• Are earnings backed by cash? 1.09×
  Cash-backed
  Cash from ops CN¥155M ÷ net income CN¥142M

  In the filing’s words The filing discloses a material weakness in its financial controls — the reported numbers here, and the record built on them, are only as reliable as the controls that produced them.

  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?

• Where do the earnings go? 16%
  Reinvests most of it
  Dividends + buybacks CN¥18M ÷ Owner Earnings CN¥113M
  What this means

  Of CN¥113M Owner Earnings, CN¥18M (16%) went back to shareholders, CN¥0 dividends, CN¥18M 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.

• Investing or harvesting? 0.98×
  Maintaining
  Capex CN¥41M ÷ depreciation CN¥42M
  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.

Graham’s defensive tests · 2 of 5 met

Graham’s numerical criteria for the defensive investor (The Intelligent Investor, ch. 14), run on the filings. A floor of safety, not a buy signal; many fine modern businesses fail his strictest liquidity rules by design.

• Adequate size —
  Revenue ≥ $2B (a dollar floor) · CN¥2.4B
  What this means

  Big enough to weather a storm. Graham's floor is a dollar figure — about $2B of revenue as a conservative modern stand-in. This company reports in its home currency and we carry no exchange rate, so we show the figure and leave the size bar for you to apply rather than convert it with a number we don't have.

• Strong liquidity Pass
  Current ratio ≥ 2× · 2.60×
  What this means

  Current assets at least twice current liabilities, near-term bills covered without touching the business. Strict by design: many cash-rich modern firms run leaner and miss it, holding their cushion in longer-dated securities.

• Conservative debt Pass
  Debt ≤ working capital · CN¥77M vs CN¥1.2B WC
  What this means

  Graham's rule that borrowings not exceed net current assets. Capital-heavy and buyback-heavy firms routinely fail it, read it next to interest coverage, not alone.

• Earnings stability Miss
  A profit every year (10-yr record) · 2 loss years
  What this means

  Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.

• Dividend record Miss
  Uninterrupted dividends · 1 of 10 yrs
  What this means

  An unbroken dividend was Graham's mark of durability. He wanted twenty years; the filings show about ten, and a single suspension breaks the streak. Non-payers, many fine modern compounders, fall outside his defensive net by design.

• Earnings growth Miss
  Earnings +33% over the record · −34%
  What this means

  At least a third more earnings than a decade ago, averaging three years at each end. Net income (not per-share), so stock splits don't distort it, buybacks and dilution show up in the share-count line instead.

• Moderate price —
  P/E ≤ 15 and P/E × P/B ≤ 22.5 · decided by the price
  What this means

  Graham's valuation gate, the wall he kept between a sound business and a sound investment. Three-year average earnings are CN¥0.18/share (latest year CN¥0.67), the averaged base the calculator's gate runs on, and book value is CN¥7.24/share. Enter a price in “What the price implies” just below for the P/E, P/B, and whether it clears. But this is the rule Buffett outgrew: there's no hard P/E law, and a wonderful business can deserve a far richer multiple if the thesis holds, treat it as the bargain-hunter's floor, not a verdict on the price.

Durability & moat, 2016–2025

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

• Profitable years 8 of 10
  What this means

  Lost money in 2 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 1 of 4 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% → 6% (2-yr avg ends)
  What this means

  Through the cycle the operating margin widened — about 5% early to 6% lately, median 5% — pricing power intact or improving.

• Reinvestment, incremental ROIC returns capital
  What this means

  The capital base barely grew: this business returns cash through dividends and buybacks rather than reinvesting. Judge it on the cash returned, not on compounding.

• Owner earnings growth +22%/yr
  What this means

  Owner earnings grew about 22% a year over the record.

• Worst year 2022 · 3.1% op. margin
  What this means

  Stayed profitable even in its hardest year, the resilience that survives recessions.

• Dividend record paid
  What this means

  Paid a dividend in 1 of the years on record.
