GEVO, Gevo Inc.

Will it survive?

• Can it pay its interest? -1.2×
  Does not cover its interest
  Operating income ($20M) ÷ interest expense $18M
  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? $84M
  Net debt against an operating loss
  Cash $81M − debt $165M
  What this means

  Netting $81M of cash and short-term investments against $165M of debt leaves $84M owed, with no operating profit this year to measure it against — understand that combination before anything else about the company. 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 -22%
  Below average through the cycle
  10-yr median, range -37%–-3%; -3% latest = NOPAT ($16M) ÷ invested capital $550M
  Industry peers: median 9%
  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 10 years (it ran -3% 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 -104%
  Consumes cash through the cycle
  8-yr median margin, range -462%–-27%; latest ($44M) = operating cash ($13M) − maintenance capex $30M
  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 -27% of revenue this year, a -104% median across 8 years. Treating stock comp as the real expense it is (less $9M of SBC) leaves ($53M).

• Are earnings backed by cash? ($13M)
  Loss, and burning cash
  Net income ($34M) · cash from operations ($13M)

  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

  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? —
  Not enough data
  What this means

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

• Investing or harvesting? 1.19×
  Maintaining
  Capex $30M ÷ depreciation & amortization as filed $25M
  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? 5.7%
  The count is rising
  Stock compensation $9M (fiscal 2025), 5.7% of revenue · no repurchases · diluted shares +5.6% 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 · 0 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 · $161M
  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 Near
  Current ratio ≥ 2× · 1.82×
  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 · $165M vs $65M 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) · 10 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 $-0.24/share (latest year $-0.14), the averaged base the calculator's gate runs on, and book value is $1.89/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, 2016–2025

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

• Profitable years 0 of 10
  What this means

  Lost money in 10 year(s), look at what happened there before trusting the average.

• Return on capital ≥ 15% 0 of 9 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 −80% → −342% (3-yr avg ends)
  What this means

  The recent-years average (−342%) sits below the early years (−80%), but the latest year (−13%) is back near the early level: a cyclical trough dragging the window down, not a one-way slide. The through-cycle median is −476% — read it across the cycle, not on the dip.

• Reinvestment, incremental ROIC −9%
  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 2021 · −11307.3% op. margin
  What this means

  Operations went underwater in 2021, understand why before trusting the good years.

• Share count +2.2%/yr
  What this means

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