Will it survive?

• Can it pay its interest? 1.4×
  Thin
  Operating income $7M ÷ interest expense $5M
  What this means

  Operating profit covers interest, but with little room. A bad year, a refinancing at higher rates, or a revenue wobble closes the gap fast.

• How heavy is the debt, net of cash? +$29M
  Net cash
  Cash $38M + ST investments $535K − debt $10M
  What this means

  Cash and short-term investments exceed every dollar of debt by $29M, 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? 92d
  Long (60+ days)
  DSO 107 + DIO 100 − DPO 115 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 19%
  High through the cycle
  7-yr median, range -9%–26%; the latest year is left out — large non-operating charges put its operating line well above pretax profit
  Industry peers: median -8%
  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 7 years, 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%
  Solid, recently turned positive
  latest $18M = operating cash $32M − maintenance capex $14M; positive each of the last 3 years, after an earlier loss stretch (10-yr median 3%)
  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 5% of revenue this year, a 3% median across 10 years.

• Are earnings backed by cash? $32M
  Loss, but cash-generative
  Net income ($2M) · cash from operations $32M
  What this means

  The company reported a net loss, so a conversion ratio isn't meaningful. What matters then is whether operations still threw off cash, here, they did.

How is the cash used?

• Where do the earnings go? —
  Not enough data
  What this means

  The filing data didn't include the inputs for this check.

• Investing or harvesting? 0.95×
  Maintaining
  Capex $14M ÷ depreciation $14M
  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 · 1 of 6 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 · $339M
  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 Near
  Current ratio ≥ 2× · 1.87×
  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 · $10M vs $105M 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) · 5 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 · none paid
  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 · −44%
  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 $0.11/share (latest year $-0.02), the averaged base the calculator's gate runs on, and book value is $1.95/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 5 of 10
  What this means

  Lost money in 5 year(s), look at what happened there before trusting the average.

• Operating margin 7% → 6% (3-yr avg ends)

  In the filing’s words The margin has held, but the filing names price competition — the pressure is present even where the margin has absorbed it so far.

  What this means

  Through the cycle the operating margin slipped — about 7% early to 6% lately, median 3% — competition or costs are biting in.

• Owner earnings growth +1%/yr
  What this means

  Owner earnings grew about 1% a year over the record.

• Worst year 2022 · −3.7% op. margin
  What this means

  Operations went underwater in 2022, understand why before trusting the good years.

• Share count +1.5%/yr
  What this means

  The share count is rising, dilution works against you on a per-share basis.

• How management talks about it Promotional
  What this means

  Results have held roughly flat while the filing leans on a promoter’s vocabulary — watch whether the words are doing work the numbers are not.
