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? $260M
  Net debt against an operating loss
  Cash $45M − debt $305M
  What this means

  Netting $45M of cash and short-term investments against $305M of debt leaves $260M 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? 120d
  Long (60+ days)
  DSO 55 + DIO 111 − DPO 45 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 5%
  Below average through the cycle
  10-yr median, range -3%–9%; -3% latest = NOPAT ($28M) ÷ invested capital $921M
  Industry peers: median 5%
  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 -3% 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 2%
  Thin through the cycle
  10-yr median margin, range -6%–5%; latest ($49M) = operating cash ($33M) − maintenance capex $15M
  Industry peers: median 0%
  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 -6% of revenue this year, a 2% median across 10 years. Treating stock comp as the real expense it is (less $28M of SBC) leaves ($77M).

• Are earnings backed by cash? ($33M)
  Loss, and burning cash
  Net income ($37M) · cash from operations ($33M)
  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.

How is the cash used?

• Where do the earnings go? —
  Not enough data
  What this means

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

• Investing or harvesting? 0.45×
  Harvesting
  Capex $15M ÷ depreciation & amortization as filed $34M
  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.

The promise and the pay packet

• How much of next year is already sold? 94%
  Next year is essentially contracted
  Contracted and not yet earned $1.1B, of which the filing expects 70% within twelve months = $774M against revenue of $825M
  What this means

  Remaining performance obligations are revenue the customer has committed to and the company has not yet earned — the nearest thing a software business has to an insurer's float. The headline total is a duration figure and can mislead badly on its own, because a contract signed for seven years counts the same as one signed for one. What matters is the part the filing itself expects to recognise within twelve months, shown here against a year of revenue. Where a company does not tag that band, both figures are withheld rather than shown half-told.

• Is the buyback buying ownership, or mopping up? 3.4%
  The count is rising
  Stock compensation $28M (fiscal 2025), 3.4% of revenue · no repurchases · diluted shares +20.8% 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 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 · $825M
  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× · 3.49×
  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 · $305M vs $447M 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 Near
  A profit every year (10-yr record) · 1 loss year
  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 Miss
  Earnings +33% over the record · −100%
  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 $0.01/share (latest year $-2.47), the averaged base the calculator's gate runs on, and book value is $43.81/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 9 of 10
  What this means

  Lost money in 1 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 4% → 2% (3-yr avg ends)
  What this means

  Through the cycle the operating margin slipped — about 4% early to 2% lately, median 5% — competition or costs are biting in.

• Reinvestment, incremental ROIC −2%
  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 2025 · −4.3% op. margin
  What this means

  Operations went underwater in 2025, understand why before trusting the good years.

• Share count +3.2%/yr
  What this means

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