Will it survive?

• Can it pay its interest? 0.1×
  Does not cover its interest
  Operating income $259M ÷ interest expense $1.8B
  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? $42.2B · 163.0× operating profit
  Heavy net debt
  Cash $1.4B − debt $43.6B
  What this means

  Netting $1.4B of cash and short-term investments against $43.6B of debt leaves $42.2B owed, about 163.0× a year's operating profit (168.3× 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? 52d
  Tight
  DSO 0 + DIO 52 − DPO 0 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 6%
  Below average through the cycle
  6-yr median, range 3%–8%; 0% latest = NOPAT $225M ÷ invested capital $60.5B
  Industry peers: median 6%
  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 6 years (it ran 0% 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 42%
  High
  Owner earnings $3.6B = operating cash $5.4B − maintenance capex $1.8B
  Industry peers: median 15%
  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 42% of revenue this year.

• Are earnings backed by cash? 1.44×
  Cash-backed
  Cash from ops $5.4B ÷ net income $3.8B
  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? 5%
  Reinvests most of it
  Dividends + buybacks $192M ÷ Owner Earnings $3.6B
  What this means

  Of $3.6B Owner Earnings, $192M (5%) went back to shareholders, $192M dividends, $0 buybacks. 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? 0.67×
  Harvesting
  Capex $1.8B ÷ depreciation $2.6B
  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 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 Pass
  Revenue ≥ $2B · $8.5B
  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 —
  Current ratio ≥ 2× · —
  What this means

  Current assets / liabilities not in the data yet.

• Earnings stability Miss
  A profit every year (10-yr record) · 2 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 · 2 of 10 yrs
  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 Pass
  Earnings +33% over the record · +187%
  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 $17.97/share (latest year $22.48), the averaged base the calculator's gate runs on, and book value is $109.80/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 8 of 10
  What this means

  Lost money in 2 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 of 8 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 47% → 42% (3-yr avg ends)
  What this means

  The recent-years average (42%) sits below the early years (47%), but the latest year (69%) is back near the early level: a cyclical trough dragging the window down, not a one-way slide. The through-cycle median is 46% — read it across the cycle, not on the dip.

• Reinvestment, incremental ROIC 2%
  What this means

  Reinvested capital came back at only a modest incremental return — near the cost of capital, where extra growth adds little per dollar. The record shows whether it is a soft stretch or a thinning moat.

• Worst year 2022 · 10.1% op. margin
  What this means

  Stayed profitable even in its hardest year, the resilience that survives recessions.

• Share count −0.8%/yr
  What this means

  The share count is shrinking, buybacks are quietly growing your slice of the business.

• Dividend record rising
  What this means

  Paid and raised the dividend across the record, the continuity Graham prized.
