The business in brief
read the 10-K →What this business is and what moves its needle, from its own SEC filings.
- What it is
- Revenue is Products (65%) and Software and other services (35%).
- Situation
- Unprofitable. No sustained operating profit across the record; an earnings multiple has nothing to rest on. What the record does show is revenue, the gross-margin trajectory, and the burn against the cash on hand. Net current asset value. Current assets alone exceed every liability combined, and the surplus is most of the balance sheet: the shape Graham called a net-net.
- What moves the needle
- Operating margin has run around −263% through the cycle on a 27% 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 63% 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 installed base and what follows it. On its own account, the filing leans hardest on customer concentration, set against the numbers in what the filing emphasizes, below.
- Is it a good business?
- Return on capital has rarely cleared the cost of capital (median −134%, above 15% in 0 of 5 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.

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 2025 the business turned a $77M loss into ($16M) of owner earnings: more cash than the profit line showed, after the non-cash charges and the capital it put back in.

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 $23M), owner earnings is nearer ($39M).
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.

FY2025 10-K · source on SEC EDGAR →
Will it survive?
- Can it pay its interest? -58.0×Does not cover its interestOperating income ($86M) ÷ interest expense $1M
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.
- Net cash, debt-freeCash $150M + ST investments $75M − debt $0
What this means
Cash and short-term investments exceed every dollar of debt by $226M, 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.
- Long (60+ days)DSO 100 + DIO 432 − DPO 38 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 enough dataIndustry peers: median -28%
What this means
The filing data didn't include the inputs for this check.
- Owner-earnings margin -179%Consumes cash through the cycle7-yr median margin, range -439%–-16%; latest ($16M) = operating cash ($13M) − maintenance capex $3MIndustry peers: median -25%
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 -16% of revenue this year, a -179% median across 7 years. Treating stock comp as the real expense it is (less $23M of SBC) leaves ($39M).
- Are earnings backed by cash? ($13M)Loss, and burning cashNet income ($77M) · cash from operations ($13M)
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?
- Not enough data
What this means
The filing data didn't include the inputs for this check.
- Investing or harvesting? 0.50×HarvestingCapex $3M ÷ depreciation $7M
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 · 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 MissRevenue ≥ $2B · $98M
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 PassCurrent ratio ≥ 2× · 3.83×
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.
- Earnings stability MissA profit every year (7-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 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 $-0.37/share (latest year $-0.30), the averaged base the calculator's gate runs on, and book value is $0.76/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, 2019–2025
Whether the record’s returns held, and what the capital reinvested earned.
- Profitable years 0 of 7
What this means
Lost money in 7 year(s), look at what happened there before trusting the average.
- Operating margin −343% → −133% (3-yr avg ends)
In the filing’s words The words confirm the number: the filing says price increases held their volume, and the margin widened with them — Buffett’s strongest mark of pricing power.
What this means
Through the cycle the operating margin widened — about −343% early to −133% lately, median −263% — pricing power intact or improving.
- Worst year 2019 · −370.9% op. margin
What this means
Operations went underwater in 2019, understand why before trusting the good years.
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.
In its own filing Raised, but not as a competitor
The filing raises AI among its risks, but in other terms (security, regulation, energy or the like), not as a competitor to its product; it frames AI mainly as a capability.
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, and the company is using it that way.

Management, ownership & pay
read the proxy →From the proxy: how much of the business the people running it own, and how they are paid, beside what the business earned for its owners in the same years.
| Fiscal year | Pay, as filed | “Actually paid” | Owner earnings |
|---|---|---|---|
| 2023 | $10.8M | $6.5M | ($105M) |
| 2023 | $217k | $127k | ($105M) |
| 2024 | $5.5M | $16.3M | ($44M) |
| 2025 | $6.4M | $8.4M | ($16M) |
Both pay figures are the company’s own, from the pay-versus-performance table its proxy statement files. “As filed” is the Summary Compensation Table total: salary, bonus, and equity awards at their value on the day of grant. “Actually paid” is the SEC’s prescribed recalculation, which re-marks those equity awards to what they became as they vested; it can swing far above or below the filed figure in either direction, and negative years occur. Owner earnings are the whole business's, from the record above, for the same fiscal years.
- Stock-based compensation$23M
The slice of the business handed to employees in shares this year, 24% of revenue. 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.

The price
What a price has to assume.
What the price implies
reverse-DCFButterfly Network 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.

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.
