CEPL, Capstone Energy Plus Inc.
A capital-goods maker, whose demand swings with its customers' own spending.
The business
What it sells, where the money comes from, the kind of company it is.
The business in brief
What this business is and what moves its needle, from its own SEC filings.
- Situation
- Distress / turnaround. Thin interest coverage, or operating cash burned against real debt, across the record. The balance sheet carries this situation; the debt schedule sets the clock.
- What moves the needle
- Operating margin has run around −24% through the cycle on a 13% gross margin, the operating line deeply negative — so the lever is the path to a margin at all: revenue growth against the cost curve and the cash runway, not the level of a margin that isn't there yet. Inventory runs near 23% of sales, so how fast it turns back into cash — and the risk of writing it down when demand softens — sits alongside the margin. Read this kind of business on the capital-goods cycle and the aftermarket.
- Is it a good business?
- Return on capital has rarely cleared the cost of capital (median −74%, above 15% in 0 of 8 years). Owner earnings, the cash-based check, have been thin too. This is price-taker territory, where the balance sheet and the cycle matter more than any multiple; the rest is in the 10-K.
Every line is arithmetic on the company's filings, shown in full in the sections below.

Owner earnings vs. net income
Owner earningsNet incomeThe accountant's number, and the cash an owner can take; the gap is the tell.
Net income is the accountant's number; owner earnings is the cash an owner could take out. The walk between them, off the cash-flow statement, and whether the gap is widening or holding.
In fiscal 2026 the business reported $3M of profit but ($3M) of owner earnings: $6M less than the profit line, taken out by capital spending and the timing of cash.

Owner earnings is the cash an owner could pull out without starving the business: operating cash less the capital it must spend to hold its position . The cash-flow statement also adds stock comp back as non-cash, but it is a real cost paid in shares; counted as the expense it is (less $777K), owner earnings is nearer ($4M).
Much of fiscal 2026's profit didn't arrive as operating cash; it sits in “working capital & other” above. That can be a real inventory or timing swing, or profit that doesn't run through operating cash at all: a heavy tax year, equity-method earnings, or investment income booked through investing. For a year like this, owner earnings understates the cash earned; the full cash-flow statement carries the rest.
Maintenance capex is estimated as depreciation where a growing business invests above it; free cash flow is the figure the scorecard's free-cash margin reads.

Owner’s Scorecard
Will it survive?
- Does not cover its interestOperating income $3M ÷ interest expense $4M
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? $23M · 6.7× operating profitHeavy net debtCash $28M − debt $51M
What this means
Netting $28M of cash and short-term investments against $51M of debt leaves $23M owed, about 6.7× a year's operating profit (15.0× 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.
- Long (60+ days)DSO 44 + DIO 112 − DPO 89 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?
- Not meaningful hereInvested capital ($22M) = debt $51M + equity ($44M) − cashIndustry peers: median 3%
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.
- Consumes cash through the cycle10-yr median margin, range -46%–8%; latest ($3M) = operating cash ($3M) − maintenance capex $835KIndustry peers: median 0%
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 -3% of revenue this year, a -23% median across 10 years. Treating stock comp as the real expense it is (less $777K of SBC) leaves ($4M).
- Are earnings backed by cash? -0.90×Thinly cash-backedCash from ops ($3M) ÷ net income $3M
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?
- Not enough data
What this means
The filing data didn't include the inputs for this check.
- Investing or harvesting? 0.20×HarvestingCapex $835K ÷ depreciation $4M
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 · 0 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 MissRevenue ≥ $2B · $106M
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 MissCurrent ratio ≥ 2× · 0.96×
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 MissDebt ≤ working capital · $51M vs ($3M) 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 MissA profit every year (10-yr record) · 8 loss years
What this means
Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.
- Dividend record MissUninterrupted dividends · none paid
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 —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 $0.05/share (latest year $0.14), the averaged base the calculator's gate runs on, and book value is $-2.13/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, 2016–2026
Whether the record’s returns held, and what the capital reinvested earned.
- Profitable years 2 of 10
What this means
Lost money in 8 year(s), look at what happened there before trusting the average.
- Return on capital ≥ 15% 0 of 8 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 −19% → −9% (3-yr avg ends)
What this means
Through the cycle the operating margin widened — about −19% early to −9% lately, median −24% — pricing power intact or improving.
- Reinvestment, incremental ROIC —
What this means
The reinvested base moved too little against the change in profit to read a reliable return on it here — the figure would be a small-denominator artifact, not a moat. Judge this one on the owner-earnings record and the cash it returns instead.
- Worst year 2022 · −31.2% op. margin
What this means
Operations went underwater in 2022, understand why before trusting the good years.
- Share count +1.4%/yr
What this means
The share count is rising, dilution works against you on a per-share basis.
Does AI threaten the moat?
Low contestabilityThe moat is physical, regulated or balance-sheet-funded, the kind AI cuts costs within but does not contest.
AI is unlikely to contest a moat that is physical, regulated or balance-sheet-funded; here it reads more as a cost tool than a threat.

Management, ownership & pay
From the proxy: how much of the business the people running it own, and how they are paid.
- Stock-based compensation$777K
The slice of the business handed to employees in shares this year, 1% of revenue, equal to 23% of operating profit. Buffett's oldest accounting fight: this is compensation, compensation is an expense, real whether or not the headline earnings admit it. One trap: the cash-flow statement adds SBC back, so the operating cash, and the owner earnings drawn from it, are flattered by exactly this amount; counted as the cost it is, what an owner keeps is lower.
Inverting the record
Invert: instead of why Capstone Energy Plus Inc. is a good business, the question is what would make owning it a mistake, and whether those marks are in the record. Disconfirming tests across 2016–2026.
1 of the 3 tests turned up something to look into; the other 2 came back clean.
- Look hereDid debt outgrow the business?$74K → $51M
Debt rose from $74K to $51M while owner earnings went from about ($18M) to ($10M): the borrowing grew and the earnings that would carry it are not there now. Debt raised for buybacks or deals rather than growth is the kind that bites in a downturn.
- Is it less profitable than it was?
- Did receivables and inventory outpace sales?
Each test is read from the filings and is noisy alone; a flag can mark a cyclical trough or a year of heavy investment as easily as a problem. The filing says which.

The price
What a price has to assume.
What the price implies
reverse-DCFCapstone Energy Plus Inc. is profitable, but owner earnings are negative this year because capital spending currently outruns operating cash, a build-out, so the owner-earnings reverse-DCF has no positive base to grow. We read the price from both ends instead: type a price to see the steady-state profitability it demands, then set the mature margin you would believe and weigh the two against each other. Nothing leaves your browser unless you enter it in your notebook.

Two reads of one future. From your price: the owner earnings the company must reach, valued at a mature multiple and discounted back at your rate, expressed as the margin it implies on revenue grown at your rate. From your belief: the mature margin you would credit, set on the dial above. When the margin the price demands runs above the one you would believe, you are paying for a future taken on faith. For a deep cyclical at a trough, normalized through-cycle earnings are the better lens; this mode is for the genuinely unprofitable, and for the profitable business whose capital spending currently outruns its cash.
