Will it survive?

• Can it pay its interest? —
  Interest expense not tagged in the data
  What this means

  No usable interest-expense line was tagged in the filing data, but the balance sheet carries real net debt — so the interest burden here is unknown, not absent. Read the debt on the net-debt check below.

• How heavy is the debt, net of cash? $749M
  Net debt against an operating loss
  Cash $347M − debt $1.1B
  What this means

  Netting $347M of cash and short-term investments against $1.1B of debt leaves $749M owed, with no operating profit this year to measure it against — understand that combination before anything else about the company. 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? 97d
  Long (60+ days)
  DSO 122 + DIO 0 − DPO 25 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. (Little or no inventory, a services / asset-light model, so the inventory leg is ~0.)

Is it a good business?

• Return on invested capital -24%
  Below average through the cycle
  5-yr median, range -48%–-16%; -16% latest = NOPAT ($300M) ÷ invested capital $1.9B
  Industry peers: median -1%
  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 -16% 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 5%
  Positive this year, negative across the cycle
  latest $61M = operating cash $64M − maintenance capex $4M (positive this year), after an earlier loss stretch (7-yr median -28%)
  Industry peers: median 18%
  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 5% of revenue this year, a -28% median across 7 years. Treating stock comp as the real expense it is (less $397M of SBC) leaves ($337M).

• Are earnings backed by cash? $64M
  Loss, but cash-generative
  Net income ($295M) · cash from operations $64M
  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.

How is the cash used?

• Where do the earnings go? 0%
  Reinvests most of it
  Dividends + buybacks $255K ÷ Owner Earnings $61M
  What this means

  Of $61M Owner Earnings, $255K (0%) went back to shareholders, $0 dividends, $255K buybacks. But the buybacks barely exceed stock issued to employees ($397M SBC), net of dilution, little was truly returned. 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? 0.12×
  Harvesting
  Capex $4M ÷ depreciation $30M
  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 · 2 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 Near
  Revenue ≥ $2B · $1.2B
  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× · 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 · $1.1B vs $1.9B 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 (7-yr record) · 7 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 $-1.05/share (latest year $-0.86), the averaged base the calculator's gate runs on, and book value is $3.40/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, 2019–2025

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

• Profitable years 0 of 7
  What this means

  Lost money in 7 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 of 5 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 −84% → −46% (3-yr avg ends)
  What this means

  Through the cycle the operating margin widened — about −84% early to −46% lately, median −65% — pricing power intact or improving.

• Reinvestment, incremental ROIC −30%
  What this means

  Reinvested capital came back at a negative incremental return over this window — the invested base grew while operating profit did not. The filings show where it went.

• Worst year 2020 · −98.6% op. margin
  What this means

  Operations went underwater in 2020, understand why before trusting the good years.
