Will it survive?

• Can it pay its interest? —
  No meaningful interest burden
  Little or no interest expense reported
  What this means

  Little or no interest expense reported, the business isn't leaning on lenders to operate.

• How heavy is the debt, net of cash? +$263M
  Net cash, debt-free
  Cash $263M − debt $0
  What this means

  Cash and short-term investments exceed every dollar of debt by $263M, on net the company owes nothing, and can act from strength when others can't. 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? 151d
  Long (60+ days)
  DSO 54 + DIO 153 − DPO 56 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 —
  Not enough data
  Industry peers: median 8%
  What this means

  The filing data didn't include the inputs for this check.

• Owner-earnings margin 26%
  High through the cycle
  10-yr median margin, range 11%–32%; latest $237M = operating cash $246M − maintenance capex $9M
  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 24% of revenue this year, a 26% median across 10 years.

• Are earnings backed by cash? 2.15×
  Cash-backed
  Cash from ops $246M ÷ net income $114M
  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? 87%
  Returns about half
  Dividends + buybacks $206M ÷ Owner Earnings $237M — this fiscal year
  What this means

  Of $237M Owner Earnings, $206M (87%) went back to shareholders, $55M dividends, $151M 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. This year's proportion is 87%; across the record (2016–2025) it is 94%, the capital-allocation section below.

• Investing or harvesting? 0.28×
  Harvesting
  Capex $9M ÷ depreciation & amortization as filed $31M
  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 Miss
  Revenue ≥ $2B · $994M
  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× · 3.80×
  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.

• 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 Miss
  Earnings +33% over the record · −38%
  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 $0.66/share (latest year $0.68), the averaged base the calculator's gate runs on, and book value is $8.87/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.

• Operating margin 30% → 15% (3-yr avg ends)
  What this means

  Through the cycle the operating margin slipped — about 30% early to 15% lately, median 21% — competition or costs are biting in.

• Owner earnings growth −0%/yr
  What this means

  Owner earnings shrank about 0% a year over the record.

• Worst year 2024 · 12.6% op. margin
  What this means

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

• Share count −0.3%/yr
  What this means

  Roughly flat share count, little dilution, little buyback.

• Dividend record rising
  What this means

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