Will it survive?

• Can it pay its interest? 26.9×
  Comfortable
  Operating income $191M ÷ interest expense $7M
  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? $12M · 0.1× operating profit
  Modest net debt
  Cash $88M − debt $100M
  What this means

  Netting $88M of cash and short-term investments against $100M of debt leaves $12M owed, about 0.1× a year's operating profit (0.5× 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? 422d
  Long (60+ days)
  DSO 113 + DIO 347 − DPO 38 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 -39%
  Below average through the cycle
  9-yr median, range -243%–44%; 31% latest = NOPAT $154M ÷ invested capital $490M
  Industry peers: median -46%
  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 9 years (it ran 31% 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 8%
  Solid, recently turned positive
  latest $42M = operating cash $50M − maintenance capex $8M; positive each of the last 3 years, after an earlier loss stretch (10-yr median -158%)
  Industry peers: median -46%
  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 8% of revenue this year, a -158% median across 10 years. It chose to put $15M more into growth, so free cash flow this year was $28M — the gap is investment, not weakness. Treating stock comp as the real expense it is (less $20M of SBC) leaves $22M.

• Are earnings backed by cash? 0.34×
  Thinly cash-backed
  Cash from ops $50M ÷ net income $147M
  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? 75%
  Returns about half
  Dividends + buybacks $32M ÷ Owner Earnings $42M — this fiscal year
  What this means

  Of $42M Owner Earnings, $32M (75%) went back to shareholders, $0 dividends, $32M buybacks. Net of $20M stock comp, the real buyback was about $12M. 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? 2.82×
  Expanding
  Capex $23M ÷ depreciation & amortization as filed $8M
  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.

The promise and the pay packet

• Is the buyback buying ownership, or mopping up? 3.9%
  Stock pay, share count unread
  Stock compensation $20M (fiscal 2025), 3.9% of revenue · repurchases $32M · the share count is not comparable across these years (a split or a first listing sits in the record), so the drift is withheld
  What this means

  Stock handed to employees is a real cost paid in the owner's own currency: it is charged against profit, but the shares it creates are permanent. Many companies repurchase stock at the same time, which looks like a return of capital and often is not — if the count barely moves, the cash merely cancelled the pay packet and bought the owner nothing. The three states worth telling apart are a count genuinely shrinking, a count standing still despite large repurchases, and a count rising because the issuance was never offset at all.

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 · $510M
  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× · 6.71×
  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 · $100M vs $397M 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) · 8 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.

• 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 $0.47/share (latest year $0.66), the averaged base the calculator's gate runs on, and book value is $2.13/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 2 of 10
  What this means

  Lost money in 8 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 −230% → 26% (3-yr avg ends)

  In the filing’s words The record and the words agree: the margin widened and the filing attributes the gain to its own pricing, not volume alone.

  What this means

  Through the cycle the operating margin widened — about −230% early to 26% lately, median −141% — pricing power intact or improving.

• Reinvestment, incremental ROIC 43%
  What this means

  Every extra dollar the business reinvested came back at a high incremental return — the lens GBM read for a moat that reinvests rather than merely harvests. The record and the 10-K are where you check whether the rate holds.

• Worst year 2018 · −354.9% op. margin
  What this means

  Operations went underwater in 2018, understand why before trusting the good years.
