Will it survive?

• Can it pay its interest? 32.6×
  Comfortable
  Operating income $34M ÷ interest expense $1M
  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? $323M · 9.5× operating profit
  Heavy net debt
  Cash $38M − debt $361M
  What this means

  Netting $38M of cash and short-term investments against $361M of debt leaves $323M owed, about 9.5× a year's operating profit (10.6× 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.

• How long is cash tied up? -37d
  Negative, funded by others
  DSO 162 + DIO 0 − DPO 199 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. (Little or no inventory, a services / asset-light model, so the inventory leg is ~0.)

Is it a good business?

• Return on invested capital -8%
  Below average through the cycle
  8-yr median, range -52%–46%; the latest year is left out — large non-operating charges put its operating line well above pretax profit
  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 8 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 2%
  Positive this year, negative across the cycle
  latest $11M = operating cash $42M − maintenance capex $31M (positive this year), after an earlier loss stretch (4-yr median -3%)
  Industry peers: median 45%
  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 2% of revenue this year, a -3% median across 4 years. Treating stock comp as the real expense it is (less $16M of SBC) leaves ($5M).

• Are earnings backed by cash? $42M
  Loss, but cash-generative
  Net income ($38M) · cash from operations $42M
  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? 0.43×
  Harvesting
  Capex $31M ÷ depreciation $71M
  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 · 0 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 Miss
  Revenue ≥ $2B · $565M
  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 Miss
  Current ratio ≥ 2× · 1.16×
  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 Miss
  Debt ≤ working capital · $361M vs $44M 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 —
  Earnings +33% over the record · —
  What this means

  Earnings were negative early in the record, a growth rate isn't meaningful.

• 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 $-1.52/share (latest year $-0.31), the averaged base the calculator's gate runs on, and book value is $1.59/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, 2017–2026

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% 2 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 −16% → −25% (3-yr avg ends)
  What this means

  The recent-years average (−25%) sits below the early years (−16%), but the latest year (6%) is back near the early level: a cyclical trough dragging the window down, not a one-way slide. The through-cycle median is 3% — read it across the cycle, not on the dip.

• Reinvestment, incremental ROIC −20%
  What this means

  Reinvested capital came back at a negative incremental return over this window — the invested base grew while operating profit did not. The filings show where it went.

• Worst year 2024 · −68.8% op. margin
  What this means

  Operations went underwater in 2024, understand why before trusting the good years.

• Share count +6.1%/yr
  What this means

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