Will it survive?

• Can it pay its interest? 1.8×
  Thin
  Operating income $505M ÷ interest expense $283M
  What this means

  Operating profit covers interest, but with little room. A bad year, a refinancing at higher rates, or a revenue wobble closes the gap fast.

• How heavy is the debt, net of cash? $6.5B · 12.9× operating profit
  Heavy net debt
  Cash $33M − debt $6.5B
  What this means

  Netting $33M of cash and short-term investments against $6.5B of debt leaves $6.5B owed, about 12.9× a year's operating profit. 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 49 + DIO 0 − DPO 85 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 4%
  Below average through the cycle
  5-yr median, range 3%–4%; 3% latest = NOPAT $315M ÷ invested capital $11.1B
  Industry peers: median 2%
  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 5 years (it ran 3% 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 through the cycle
  9-yr median margin, range -11%–20%; latest $155M = operating cash $594M − maintenance capex $438M
  Industry peers: median 11%
  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 6% of revenue this year, a 8% median across 9 years.

• Are earnings backed by cash? 5.48×
  Cash-backed
  Cash from ops $594M ÷ net income $108M
  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? 129%
  Returned more than it generated
  Dividends + buybacks $201M ÷ Owner Earnings $155M — this fiscal year
  What this means

  The company returned more than it generated: against $155M of Owner Earnings, $201M (129%) went back to shareholders, $201M dividends, $0 buybacks — the excess came from the balance sheet or borrowing, not the year's operations. Sustained, that pattern draws down cash or adds debt; the net-debt line above shows where it stands. This year's proportion is 129%; across the record (2017–2025) it is 168%, the capital-allocation section below.

• Investing or harvesting? 1.09×
  Maintaining
  Capex $438M ÷ depreciation $400M
  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 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 Pass
  Revenue ≥ $2B · $2.4B
  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× (waived for utilities) · exempt
  What this means

  Graham exempted public utilities from this test: their working capital “takes care of itself” through the continuous bond-and-share financing of growth, so a thin current ratio is the industry's structure, not a warning. His substitute test — debt no more than twice book equity — is the next line.

• Conservative debt Pass
  Debt ≤ 2× equity (Graham's utility test) · $6.5B vs $4.6B equity
  What this means

  Graham's own substitution for public utilities: debt not exceeding twice the stock equity at book value, in place of the working-capital tests an industrial faces. A utility finances its plant with bonds by design; the question is whether the borrowing stays inside the equity behind it.

• Earnings stability Miss
  A profit every year (9-yr record) · 3 loss years
  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 (9)
  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 · −316%
  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 $-0.63/share (latest year $0.14), the averaged base the calculator's gate runs on, and book value is $6.04/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, 2017–2025

Whether the record’s returns held, and what the capital reinvested earned.

• Profitable years 6 of 9
  What this means

  Lost money in 3 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 of 9 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 23% → 20% (3-yr avg ends)
  What this means

  Through the cycle the operating margin slipped — about 23% early to 20% lately, median 21% — competition or costs are biting in.

• 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.

• Owner earnings growth −3%/yr
  What this means

  Owner earnings shrank about 3% a year over the record.

• Worst year 2022 · 14.5% op. margin
  What this means

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

• Dividend record rising
  What this means

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