Will it survive?

• Can it pay its interest? 9.1×
  Comfortable
  Operating income $404M ÷ interest expense $44M
  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? $1.5B · 3.7× operating profit
  Meaningful net debt
  Cash $500M − debt $2.0B
  What this means

  Netting $500M of cash and short-term investments against $2.0B of debt leaves $1.5B owed, about 3.7× a year's operating profit (5.0× 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? 11d
  Tight
  DSO 25 + DIO 7 − DPO 21 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 17%
  High through the cycle
  10-yr median, range 12%–30%; 12% latest = NOPAT $335M ÷ invested capital $2.7B
  Industry peers: median 8%
  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 12% 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 11%
  Solid through the cycle
  10-yr median margin, range 6%–15%; latest $371M = operating cash $480M − maintenance capex $109M
  Industry peers: median 8%
  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 12% of revenue this year, a 11% median across 10 years. It chose to put $75M more into growth, so free cash flow this year was $295M — the gap is investment, not weakness. Treating stock comp as the real expense it is (less $26M of SBC) leaves $345M.

• Are earnings backed by cash? 1.46×
  Cash-backed
  Cash from ops $480M ÷ net income $329M
  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? 33%
  Reinvests most of it
  Dividends + buybacks $122M ÷ Owner Earnings $371M — this fiscal year
  What this means

  Of $371M Owner Earnings, $122M (33%) went back to shareholders, $92M dividends, $30M buybacks. Net of $26M stock comp, the real buyback was about $4M. 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. This year's proportion is 33%; across the record (2016–2025) it is 68%, the capital-allocation section below.

• Investing or harvesting? 1.69×
  Expanding
  Capex $185M ÷ depreciation & amortization as filed $109M
  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? 0.8%
  The buyback only stands still
  Stock compensation $26M (fiscal 2025), 0.8% of revenue · repurchases $30M · diluted shares +0.2% since 2022
  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 · 5 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 Pass
  Revenue ≥ $2B · $3.2B
  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× · 2.32×
  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 · $2.0B vs $888M 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 Pass
  A profit every year (10-yr record) · no losses
  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 Pass
  Earnings +33% over the record · +54%
  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 $3.12/share (latest year $3.59), the averaged base the calculator's gate runs on, and book value is $13.45/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 10 of 10
  What this means

  Never lost money over the record, the earnings stability Graham insisted on.

• 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 16% → 14% (3-yr avg ends)

  In the filing’s words The words explain the slip: the filing names price competition rather than pricing actions of its own — a business that looks to take its price, not set it.

  What this means

  Through the cycle the operating margin slipped — about 16% early to 14% lately, median 16% — competition or costs are biting in.

• Reinvestment, incremental ROIC 8%
  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 +8%/yr
  What this means

  Owner earnings grew about 8% a year over the record.

• Worst year 2025 · 12.6% op. margin
  What this means

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

• Share count −1.4%/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.
