Will it survive?

• Can it pay its interest? -1095.7×
  Does not cover its interest
  Operating income ($28M) ÷ interest expense $26K
  What this means

  A full year of operating profit didn't cover the interest bill. This is the zombie zone: the business depends on refinancing, asset sales, or forbearance to service its debt.

• How heavy is the debt, net of cash? +$17M
  Net cash
  Cash $18M − debt $690K
  What this means

  Cash and short-term investments exceed every dollar of debt by $17M, 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? 168d
  Long (60+ days)
  DSO 91 + DIO 131 − DPO 54 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 -1%
  Below average through the cycle
  10-yr median, range -63%–31%; -62% latest = NOPAT ($23M) ÷ invested capital $36M
  Industry peers: median -3%
  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 -62% 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 9%
  Positive this year, negative across the cycle
  latest $7M = operating cash $8M − maintenance capex $950K (positive this year), after an earlier loss stretch (10-yr median -7%)
  Industry peers: median 6%
  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 9% of revenue this year, a -7% median across 10 years. Treating stock comp as the real expense it is (less $1M of SBC) leaves $6M.

• Are earnings backed by cash? $8M
  Loss, but cash-generative
  Net income ($30M) · cash from operations $8M
  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? 59%
  Returns about half
  Dividends + buybacks $4M ÷ Owner Earnings $7M
  What this means

  Of $7M Owner Earnings, $4M (59%) went back to shareholders, $0 dividends, $4M buybacks. Net of $1M stock comp, the real buyback was about $3M. 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? 0.35×
  Harvesting
  Capex $950K ÷ depreciation $3M
  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 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 · $79M
  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× · 2.94×
  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 · $690K vs $40M 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) · 6 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 · −792%
  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 $-1.18/share (latest year $-2.09), the averaged base the calculator's gate runs on, and book value is $3.68/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 4 of 10
  What this means

  Lost money in 6 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 1 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 1% → −19% (3-yr avg ends)

  In the filing’s words The words explain the slip: the filing names price competition rather than pricing actions of its own — a business that looks to take its price, not set it.

  What this means

  Through the cycle the operating margin slipped — about 1% early to −19% lately, median −1% — competition or costs are biting in.

• 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 −7%/yr
  What this means

  Owner earnings shrank about 7% a year over the record.

• Worst year 2025 · −35.9% op. margin
  What this means

  Operations went underwater in 2025, understand why before trusting the good years.

• Share count +0.9%/yr
  What this means

  Roughly flat share count, little dilution, little buyback.
