Will it survive?

• Can it pay its interest? -14.9×
  Does not cover its interest
  Operating income ($1.2B) ÷ interest expense $84M
  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? +$889M
  Net cash
  Cash $510M + ST investments $920M − debt $541M
  What this means

  Cash and short-term investments exceed every dollar of debt by $889M, 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? 240d
  Long (60+ days)
  DSO 85 + DIO 392 − DPO 237 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 -138%
  Below average through the cycle
  10-yr median, range -421%–-83%; -128% latest = NOPAT ($985M) ÷ invested capital $769M
  Industry peers: median -16%
  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 -128% 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 -178%
  Consumes cash through the cycle
  7-yr median margin, range -197%–-137%; latest ($958M) = operating cash ($935M) − maintenance capex $23M
  Industry peers: median -13%
  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 -158% of revenue this year, a -178% median across 7 years. Treating stock comp as the real expense it is (less $153M of SBC) leaves ($1.1B).

• Are earnings backed by cash? ($935M)
  Loss, and burning cash
  Net income ($1.3B) · cash from operations ($935M)
  What this means

  The company reported a net loss, so a conversion ratio isn't meaningful. What matters then is whether operations still threw off cash, here, they did not.

The promise and the pay packet

• Is the buyback buying ownership, or mopping up? 25.2%
  The count is rising
  Stock compensation $153M (fiscal 2025), 25.2% of revenue · no repurchases · diluted shares +61.8% 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 · 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 Miss
  Revenue ≥ $2B · $606M
  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× · 3.83×
  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 Pass
  Debt ≤ working capital · $541M vs $1.3B 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 Miss
  A profit every year (10-yr record) · 10 loss years
  What this means

  Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.

• Dividend record —
  Uninterrupted dividends · no dividend line tagged in the data
  What this means

  An unbroken dividend was Graham's mark of durability. This record carries no dividends-paid line in any year — common for partnerships, whose distributions file under tags the chain doesn't read — so the criterion is withheld rather than judged on silence.

• 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 $-4.49/share (latest year $-5.85), the averaged base the calculator's gate runs on, and book value is $3.38/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 0 of 10
  What this means

  Lost money in 10 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 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 −1153% → −227% (3-yr avg ends)
  What this means

  Through the cycle the operating margin widened — about −1153% early to −227% lately, median −206% — pricing power intact or improving.

• Reinvestment, incremental ROIC —
  What this means

  The reinvested base moved too little against the change in profit to read a reliable return on it here — the figure would be a small-denominator artifact, not a moat. Judge this one on the owner-earnings record and the cash it returns instead.

• Worst year 2018 · −3124.9% op. margin
  What this means

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