Will it survive?

• Can it pay its interest? 3.8×
  Adequate
  Operating income $212M ÷ interest expense $57M
  What this means

  Comfortable in a normal year, but below the margin of safety Graham looked for. Worth checking how stable the coverage has been across a full cycle.

• How heavy is the debt, net of cash? $269M · 1.3× operating profit
  Modest net debt
  Cash $164M − debt $433M
  What this means

  Netting $164M of cash and short-term investments against $433M of debt leaves $269M owed, about 1.3× a year's operating profit (2.0× 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? 80d
  Long (60+ days)
  DSO 13 + DIO 91 − DPO 23 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
  5-yr median, range -1%–10%; 10% latest = NOPAT $155M ÷ invested capital $1.6B
  Industry peers: median 11%
  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 10% 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 4%
  Thin through the cycle
  7-yr median margin, range -1%–20%; latest $147M = operating cash $224M − maintenance capex $77M
  Industry peers: median 8%
  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 10% of revenue this year, a 4% median across 7 years.

• Are earnings backed by cash? 1.46×
  Cash-backed
  Cash from ops $224M ÷ net income $153M

  In the filing’s words The filing discloses a material weakness in its financial controls — the reported numbers here, and the record built on them, are only as reliable as the controls that produced them.

  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? 165%
  Returned more than it generated
  Dividends + buybacks $243M ÷ Owner Earnings $147M — this fiscal year
  What this means

  The company returned more than it generated: against $147M of Owner Earnings, $243M (165%) went back to shareholders, $0 dividends, $243M buybacks — the excess came from the balance sheet or borrowing, not the year's operations. Sustained, that pattern draws down cash or adds debt; the net-debt line above shows where it stands. This year's proportion is 165%; across the record (2018–2024) it is 77%, the capital-allocation section below.

• Investing or harvesting? 0.60×
  Harvesting
  Capex $77M ÷ depreciation & amortization as filed $129M
  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? 1.8%
  The count is genuinely shrinking
  Stock compensation $26M (fiscal 2024), 1.8% of revenue · repurchases $243M · diluted shares -5.9% since 2021
  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 · 1 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 · $1.4B
  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× · 2.17×
  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 Miss
  Debt ≤ working capital · $433M vs $254M 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) · 2 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 $0.66/share (latest year $1.07), the averaged base the calculator's gate runs on, and book value is $9.45/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, 2018–2024

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

• Profitable years 5 of 7
  What this means

  Lost money in 2 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 of 6 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% → 11% (3-yr avg ends)

  In the filing’s words The margin widened even though the filing names price competition — the gain came from volume or cost, not pricing power. Read where.

  What this means

  Through the cycle the operating margin widened — about 4% early to 11% lately, median 9% — pricing power intact or improving.

• 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.

• Owner earnings growth +40%/yr
  What this means

  Owner earnings grew about 40% a year over the record.

• Worst year 2020 · −2.4% op. margin
  What this means

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

• Share count +5.3%/yr
  What this means

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