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? +$319M
  Net cash, debt-free
  Cash $319M − debt $0
  What this means

  Cash and short-term investments exceed every dollar of debt by $319M, 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? 73d
  Long (60+ days)
  DSO 72 + DIO 47 − DPO 46 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 2%
  What this means

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

• Owner-earnings margin 13%
  Positive this year, negative across the cycle
  latest $207M = operating cash $236M − maintenance capex $29M (positive this year), after an earlier loss stretch (6-yr median -18%)
  Industry peers: median 16%
  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 13% of revenue this year, a -18% median across 6 years. Treating stock comp as the real expense it is (less $315M of SBC) leaves ($108M).

• Are earnings backed by cash? $236M
  Loss, but cash-generative
  Net income ($9M) · cash from operations $236M

  In the filing’s words And the filing leans heavily on adjusted, non-GAAP earnings — steering you off the GAAP figure just where the cash is not backing it. Read the reconciliation in the notes before taking the adjusted number.

  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 $0 ÷ Owner Earnings $207M
  What this means

  Of $207M Owner Earnings, $0 (0%) went back to shareholders, $0 dividends, $0 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.

• Investing or harvesting? 1.20×
  Maintaining
  Capex $29M ÷ depreciation $24M
  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 · 0 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 Near
  Revenue ≥ $2B · $1.6B
  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 Near
  Current ratio ≥ 2× · 1.64×
  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 (6-yr record) · 6 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 $-0.26/share (latest year $-0.02), the averaged base the calculator's gate runs on, and book value is $2.44/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, 2021–2026

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

• Profitable years 0 of 6
  What this means

  Lost money in 6 year(s), look at what happened there before trusting the average.

• Operating margin −69% → −18% (3-yr avg ends)
  What this means

  Through the cycle the operating margin widened — about −69% early to −18% lately, median −40% — pricing power intact or improving.

• Worst year 2021 · −83.8% op. margin
  What this means

  Operations went underwater in 2021, understand why before trusting the good years.
