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? +$38M
  Net cash
  Cash $43M − debt $5M
  What this means

  Cash and short-term investments exceed every dollar of debt by $38M, 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? 285d
  Long (60+ days)
  DSO 50 + DIO 317 − DPO 82 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?

• Return on invested capital -127%
  Below average through the cycle
  4-yr median, range -1239%–1%; 1% latest = NOPAT $508K ÷ invested capital $73M
  Industry peers: median -32%
  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 1% 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 26%
  Positive this year, negative across the cycle
  latest $22M = operating cash $23M − maintenance capex $238K (positive this year), after an earlier loss stretch (3-yr median -51%)
  Industry peers: median -56%
  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 26% of revenue this year, a -51% median across 3 years.

• Are earnings backed by cash? 8.34×
  Cash-backed
  Cash from ops $23M ÷ net income $3M
  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? 27%
  Reinvests most of it
  Dividends + buybacks $6M ÷ Owner Earnings $22M — this fiscal year
  What this means

  Of $22M Owner Earnings, $6M (27%) went back to shareholders, $0 dividends, $6M 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? 6.50×
  Expanding
  Capex $2M ÷ property depreciation $238K
  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 4 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 Miss
  Revenue ≥ $2B · $85M
  What this means

  Big enough to weather a storm. Graham's 1972 floor was ~$100M of sales (≈ $700M today); we use a $2B revenue line as a conservative modern stand-in.

• Strong liquidity Pass
  Current ratio ≥ 2× · 10.92×
  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 · $5M vs $109M 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 (5-yr record) · 4 loss years
  What this means

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

• Dividend record —
  Uninterrupted dividends · no dividend line tagged in the data
  What this means

  An unbroken dividend was Graham's mark of durability. This record carries no dividends-paid line in any year — common for partnerships, whose distributions file under tags the chain doesn't read — so the criterion is withheld rather than judged on silence.

• 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 $-0.69/share (latest year $0.08), the averaged base the calculator's gate runs on, and book value is $3.21/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, 2021–2025

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

• Profitable years 1 of 5
  What this means

  Lost money in 4 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 of 3 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 −968% → −16% (2-yr avg ends)
  What this means

  Through the cycle the operating margin widened — about −968% early to −16% lately, median −690% — 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.

• Worst year 2023 · −1849.0% op. margin
  What this means

  Operations went underwater in 2023, understand why before trusting the good years.
