Will it survive?

• Can it pay its interest? 9.0×
  Comfortable
  Operating income $299M ÷ interest expense $33M
  What this means

  Operating profit covers interest with the kind of margin Graham wanted for a defensive holding. Necessary, not sufficient, it says solvent, not cheap.

• How heavy is the debt, net of cash? $334M · 1.1× operating profit
  Modest net debt
  Cash $236M − debt $570M
  What this means

  Netting $236M of cash and short-term investments against $570M of debt leaves $334M owed, about 1.1× a year's operating profit (1.9× 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? 89d
  Long (60+ days)
  DSO 66 + DIO 81 − DPO 58 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 36%
  Very high (≥25%) through the cycle
  5-yr median, range 33%–39%; 33% latest = NOPAT $233M ÷ invested capital $712M
  Industry peers: median 12%
  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 33% 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 8%
  Solid through the cycle
  5-yr median margin, range 3%–12%; latest $149M = operating cash $203M − maintenance capex $54M
  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 8% of revenue this year, a 8% median across 5 years. Treating stock comp as the real expense it is (less $12M of SBC) leaves $136M.

• Are earnings backed by cash? 0.98×
  Mostly cash-backed
  Cash from ops $203M ÷ net income $207M
  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? 52%
  Returns about half
  Dividends + buybacks $78M ÷ Owner Earnings $149M — this fiscal year
  What this means

  Of $149M Owner Earnings, $78M (52%) went back to shareholders, $17M dividends, $61M buybacks. Net of $12M stock comp, the real buyback was about $48M. 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. This year's proportion is 52%; across the record (2021–2025) it is 16%, the capital-allocation section below.

• Investing or harvesting? 1.80×
  Expanding
  Capex $54M ÷ depreciation & amortization as filed $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.

The promise and the pay packet

• Is the buyback buying ownership, or mopping up? 0.7%
  The buyback only stands still
  Stock compensation $12M (fiscal 2025), 0.7% of revenue · repurchases $61M · diluted shares -0.6% 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 Near
  Revenue ≥ $2B · $1.8B
  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× · 2.42×
  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 Near
  Debt ≤ working capital · $570M vs $524M 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 Pass
  A profit every year (5-yr record) · no losses
  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 · 2 of 5 yrs
  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.

• 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 $2.31/share (latest year $2.54), the averaged base the calculator's gate runs on, and book value is $4.64/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 5 of 5
  What this means

  Never lost money over the record, the earnings stability Graham insisted on.

• Return on capital ≥ 15% 4 of 4 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 14% → 16% (2-yr avg ends)

  In the filing’s words The filing ties gains to its own pricing, but names price competition too — pricing power that is real yet contested, not unopposed. The margin shows who is winning.

  What this means

  Through the cycle the operating margin widened — about 14% early to 16% lately, median 15% — 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 −9%/yr
  What this means

  Owner earnings shrank about 9% a year over the record.

• Worst year 2022 · 13.1% op. margin
  What this means

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

• Share count −0.2%/yr
  What this means

  Roughly flat share count, little dilution, little buyback.

• Dividend record rising
  What this means

  Paid and raised the dividend across the record, the continuity Graham prized.

• How management talks about it Owner’s terms
  What this means

  Returns have thinned, but the filing discusses it in an owner’s vocabulary rather than selling past it — candor about a hard stretch counts for more than an adjective.
