WULF, TeraWulf Inc.

Will it survive?

• Can it pay its interest? -2.3×
  Does not cover its interest
  Operating income ($186M) ÷ interest expense $80M
  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? +$168M
  Net cash
  Cash $3.3B − debt $3.1B
  What this means

  Cash and short-term investments exceed every dollar of debt by $168M, on net the company owes nothing, and can act from strength when others can't. 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 meaningful here
  Invested capital ($27M) = debt $3.1B + equity $140M − cash
  Industry peers: median -34%
  What this means

  Invested capital is near zero or negative, usually years of buybacks pulling equity down. ROIC explodes or flips sign and stops meaning anything. Judge this one on Owner Earnings instead.

• Owner-earnings margin -5%
  Consumes cash through the cycle
  8-yr median margin, range -231%–4%; latest ($130M) = operating cash ($123M) − maintenance capex $7M
  Industry peers: median -45%
  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 -77% of revenue this year, a -5% median across 8 years. It chose to put $1.1B more into growth, so free cash flow this year was ($1.2B) — the gap is investment, not weakness. Treating stock comp as the real expense it is (less $51M of SBC) leaves ($181M).

• Are earnings backed by cash? ($123M)
  Loss, and burning cash
  Net income ($661M) · cash from operations ($123M)
  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? —
  No surplus to allocate
  What this means

  The business didn't generate positive Owner Earnings this year, so any distributions came from the balance sheet or borrowing, not from operations.

• Investing or harvesting? —
  Not enough data
  What this means

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

The promise and the pay packet

• Is the buyback buying ownership, or mopping up? 30.2%
  Stock pay, share count unread
  Stock compensation $51M (fiscal 2025), 30.2% of revenue · repurchases $33M · the share count is not comparable across these years (a split or a first listing sits in the record), so the drift is withheld
  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 Miss
  Revenue ≥ $2B · $168M
  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× · 2.00×
  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 · $3.1B vs $1.7B 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 (8-yr record) · 7 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 $-0.54/share (latest year $-1.33), the averaged base the calculator's gate runs on, and book value is $0.28/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, 2017–2025

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

• Profitable years 1 of 8
  What this means

  Lost money in 7 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 of 7 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% → −69% (3-yr avg ends)
  What this means

  Through the cycle the operating margin slipped — about −2% early to −69% lately, median −42% — competition or costs are biting in.

• Reinvestment, incremental ROIC −24%
  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 2022 · −291.0% op. margin
  What this means

  Operations went underwater in 2022, understand why before trusting the good years.
