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? +$709M
  Net cash, debt-free
  Cash $709M − debt $0
  What this means

  Cash and short-term investments exceed every dollar of debt by $709M, 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? 187d
  Long (60+ days)
  DSO 78 + DIO 155 − DPO 47 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 -77%
  What this means

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

• Owner-earnings margin 36%
  High through the cycle
  8-yr median margin, range -5237%–54%; latest $209M = operating cash $209M − maintenance capex $58K
  Industry peers: median -44%
  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 35% of revenue this year, a 36% median across 8 years. Treating stock comp as the real expense it is (less $25M of SBC) leaves $184M.

• Are earnings backed by cash? 0.97×
  Mostly cash-backed
  Cash from ops $209M ÷ net income $214M
  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? 12%
  Reinvests most of it
  Dividends + buybacks $25M ÷ Owner Earnings $209M
  What this means

  Of $209M Owner Earnings, $25M (12%) went back to shareholders, $0 dividends, $25M buybacks. Net of $25M stock comp, the real buyback was about $522K. 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? 0.15×
  Harvesting
  Capex $58K ÷ depreciation $375K
  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 · 1 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 Miss
  Revenue ≥ $2B · $589M
  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× · 6.08×
  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 Miss
  A profit every year (10-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 Miss
  Uninterrupted dividends · none paid
  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 —
  Earnings +33% over the record · —
  What this means

  Earnings were negative early in the record, a growth rate isn't meaningful.

• 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 $1.22/share (latest year $1.75), the averaged base the calculator's gate runs on, and book value is $7.80/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 7 of 10
  What this means

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

• Operating margin −2331% → 35% (3-yr avg ends)

  In the filing’s words The filing ties gains to its own pricing, but names price competition too — pricing power that is real yet contested, not unopposed. The margin shows who is winning.

  What this means

  Through the cycle the operating margin widened — about −2331% early to 35% lately, median 35% — pricing power intact or improving.

• Worst year 2018 · −7059.0% op. margin
  What this means

  Operations went underwater in 2018, understand why before trusting the good years.

• Share count +4.9%/yr
  What this means

  The share count is rising, dilution works against you on a per-share basis.
