Will it survive?

• Can it pay its interest? 0.3×
  Does not cover its interest
  Operating income $7M ÷ interest expense $28M
  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? $337M · 45.4× operating profit
  Heavy net debt
  Cash $24M − debt $361M
  What this means

  Netting $24M of cash and short-term investments against $361M of debt leaves $337M owed, about 45.4× a year's operating profit (48.7× on the gross debt, before the cash). 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? —
  Not enough data
  What this means

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

Is it a good business?

• Return on invested capital —
  Not enough data
  Industry peers: median 4%
  What this means

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

• Owner-earnings margin 4%
  Thin, recently turned positive
  latest $14M = operating cash $36M − maintenance capex $22M; positive each of the last 3 years, after an earlier loss stretch (5-yr median 5%)
  Industry peers: median 6%
  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 4% of revenue this year, a 5% median across 5 years. It chose to put $48M more into growth, so free cash flow this year was ($34M) — the gap is investment, not weakness. Treating stock comp as the real expense it is (less $6M of SBC) leaves $8M.

• Are earnings backed by cash? 8.52×
  Cash-backed
  Cash from ops $36M ÷ net income $4M
  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? —
  Not enough data
  What this means

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

• Investing or harvesting? 3.15×
  Expanding
  Capex $71M ÷ depreciation & amortization as filed $22M
  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

• Is the buyback buying ownership, or mopping up? 1.9%
  The count is rising
  Stock compensation $6M (fiscal 2025), 1.9% of revenue · no repurchases · diluted shares +12.2% 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 · 0 of 2 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 · $349M
  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 —
  Current ratio ≥ 2× (waived for utilities) · exempt
  What this means

  Graham exempted public utilities from this test: their working capital “takes care of itself” through the continuous bond-and-share financing of growth, so a thin current ratio is the industry's structure, not a warning. His substitute test — debt no more than twice book equity — is the next line.

• Conservative debt —
  Debt ≤ 2× equity (Graham's utility test) · —
  What this means

  Equity or total debt is not readable in the structured data this year, so Graham's utility debt test can't be run honestly.

• Earnings stability Near
  A profit every year (5-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.

• 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 $0.27/share (latest year $0.15), the averaged base the calculator's gate runs on, and book value is $-0.45/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, 2021–2025

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

• Profitable years 4 of 5
  What this means

  Lost money in 1 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 of 3 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 5% → 5% (2-yr avg ends)

  In the filing’s words The margin has held, but the filing names price competition — the pressure is present even where the margin has absorbed it so far.

  What this means

  Through the cycle the operating margin held roughly steady — about 5% early, 5% lately, median 3%.

• Reinvestment, incremental ROIC returns capital
  What this means

  The capital base barely grew: this business returns cash through dividends and buybacks rather than reinvesting. Judge it on the cash returned, not on compounding.

• Worst year 2025 · 2.1% op. margin
  What this means

  Stayed profitable even in its hardest year, the resilience that survives recessions.
