Will it survive?

• Can it pay its interest? 3.8×
  Adequate
  Operating income $22M ÷ interest expense $6M
  What this means

  Comfortable in a normal year, but below the margin of safety Graham looked for. Worth checking how stable the coverage has been across a full cycle.

• How heavy is the debt, net of cash? $85M · 3.9× operating profit
  Meaningful net debt
  Cash $50M − debt $135M
  What this means

  Netting $50M of cash and short-term investments against $135M of debt leaves $85M owed, about 3.9× a year's operating profit (6.1× 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? 129d
  Long (60+ days)
  DSO 50 + DIO 97 − DPO 18 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 8%
  Solid through the cycle
  10-yr median, range -17%–21%; 4% latest = NOPAT $22M ÷ invested capital $514M
  Industry peers: median 15%
  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 4% 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 17%
  High through the cycle
  10-yr median margin, range -16%–75%; latest $26M = operating cash $51M − maintenance capex $25M
  Industry peers: median 14%
  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 17% median across 10 years. It chose to put $23M more into growth, so free cash flow this year was $2M — the gap is investment, not weakness. Treating stock comp as the real expense it is (less $8M of SBC) leaves $17M.

• Are earnings backed by cash? 2.90×
  Cash-backed
  Cash from ops $51M ÷ net income $18M
  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? 39%
  Reinvests most of it
  Dividends + buybacks $10M ÷ Owner Earnings $26M
  What this means

  Of $26M Owner Earnings, $10M (39%) went back to shareholders, $7M dividends, $3M buybacks. But the buybacks barely exceed stock issued to employees ($8M SBC), net of dilution, little was truly returned. 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? 1.92×
  Expanding
  Capex $49M ÷ depreciation $25M
  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 · 3 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 · $277M
  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× · 3.09×
  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 · $135M vs $145M 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 Near
  A profit every year (10-yr record) · 1 loss year
  What this means

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

• Dividend record Pass
  Uninterrupted dividends · paid every year (10)
  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 · −88%
  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 $0.52/share (latest year $2.35), the averaged base the calculator's gate runs on, and book value is $57.37/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 9 of 10
  What this means

  Lost money in 1 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 5 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 21% → −3% (3-yr avg ends)

  In the filing’s words Input costs rose and the filing says it could not fully pass them on — which is where this margin compressed.

  What this means

  Through the cycle the operating margin slipped — about 21% early to −3% lately, median 15% — competition or costs are biting in.

• Reinvestment, incremental ROIC −10%
  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.

• Owner earnings growth −16%/yr
  What this means

  Owner earnings shrank about 16% a year over the record.

• Worst year 2023 · −32.7% op. margin
  What this means

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

• Share count +1.0%/yr
  What this means

  Roughly flat share count, little dilution, little buyback.

• Dividend record paid
  What this means

  Paid a dividend in 10 of the years on record.
