TWIN, Twin Disc Incorporated

Will it survive?

• Can it pay its interest? 5.8×
  Comfortable
  Operating income $18M ÷ interest expense $3M
  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? $30M · 1.7× operating profit
  Modest net debt
  Cash $0 − debt $30M
  What this means

  Netting $0 of cash and short-term investments against $30M of debt leaves $30M owed, about 1.7× a year's operating profit. 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? 257d
  Long (60+ days)
  DSO 64 + DIO 233 − DPO 40 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 6%
  Below average through the cycle
  9-yr median, range -17%–7%; 7% latest = NOPAT $18M ÷ invested capital $249M
  Industry peers: median 6%
  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 9 years (it ran 7% 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, recently turned positive
  latest $9M = operating cash $23M − maintenance capex $14M; positive each of the last 3 years, after an earlier loss stretch (10-yr median 1%)
  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 2% of revenue this year, a 1% median across 10 years.

• Are earnings backed by cash? 0.85×
  Mostly cash-backed
  Cash from ops $23M ÷ net income $27M
  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? 25%
  Reinvests most of it
  Dividends + buybacks $2M ÷ Owner Earnings $9M — this fiscal year
  What this means

  Of $9M Owner Earnings, $2M (25%) went back to shareholders, $2M 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. This year's proportion is 25%; across the record (2017–2026) it is 20%, the capital-allocation section below.

• Investing or harvesting? 1.00×
  Maintaining
  Capex $14M ÷ depreciation & amortization as filed $14M
  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 · 3 of 6 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 · $381M
  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× · 2.35×
  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 · $30M vs $160M 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 (10-yr record) · 4 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 · 3 of 10 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.

• Earnings growth Pass
  Earnings +33% over the record · +169%
  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 $0.86/share (latest year $1.86), the averaged base the calculator's gate runs on, and book value is $15.11/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, 2017–2026

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

• Profitable years 6 of 10
  What this means

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

  Through the cycle the operating margin widened — about 2% early to 4% lately, median 4% — pricing power intact or improving.

• Reinvestment, incremental ROIC 9%
  What this means

  Reinvested capital came back at only a modest incremental return — near the cost of capital, where extra growth adds little per dollar. The record shows whether it is a soft stretch or a thinning moat.

• Owner earnings growth +62%/yr
  What this means

  Owner earnings grew about 62% a year over the record.

• Worst year 2020 · −16.3% op. margin
  What this means

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

• Share count +2.9%/yr
  What this means

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

• Dividend record rising
  What this means

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