The business in brief

read the 10-K →

What this business is and what moves its needle, from its own SEC filings.

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 −72% through the cycle on a 55% gross margin, the operating line in the red even at its best — so the lever is whether the spending below the gross line can come down enough to clear a profit: revenue growth against the cost curve, and the cash runway until it does. Inventory runs near 20% 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 pricing power & competition, set against the numbers in what the filing emphasizes, below.

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 earned ($52M) of owner earnings, the operating cash left after the $2M it takes just to hold its position. It put $4M more into growth; free cash flow, after that spending, was ($56M).

Owner-earnings marginowner earnings ÷ revenue-52%-76%-274%

Owner earnings is the cash an owner could pull out without starving the business: operating cash less the maintenance capital it must spend to hold its position (here about $2M, roughly its depreciation, the rate its assets wear out). The other $4M of its capital spending is growth it chose, not upkeep it owed; charged only with the maintenance it must do, the business earns well more than the year's free cash flow shows. 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 $16M), owner earnings is nearer ($69M).

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

FY2025 10-K · source on SEC EDGAR →

Will it survive?

  • No meaningful interest burden
    Little or no interest expense reported
    What this means

    Little or no interest expense reported, the business isn't leaning on lenders to operate.

  • Net cash, debt-free
    Cash $32M + ST investments $188M − debt $0
    What this means

    Cash and short-term investments exceed every dollar of debt by $219M, 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 62 + DIO 177 − DPO 41 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 data
    Industry peers: median -32%
    What this means

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

  • Consumes cash through the cycle
    3-yr median margin, range -274%–-52%; latest ($52M) = operating cash ($51M) − maintenance capex $2M
    Industry peers: median -51%
    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 -52% of revenue this year, a -76% median across 3 years. Treating stock comp as the real expense it is (less $16M of SBC) leaves ($69M).

  • Loss, and burning cash
    Net income ($73M) · cash from operations ($51M)
    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? 3.37×
    Expanding
    Capex $5M ÷ property depreciation $2M
    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

  • Growth is being bought
    Selling and marketing $61M ÷ revenue $100M
    What this means

    Sales and marketing as a share of revenue, kept apart from administrative overhead because it answers a different question: how much a business must spend to win the next customer. A company whose product pulls customers in spends little here and keeps the difference; one that must buy its growth is running to stand still, and the spending has to keep rising for revenue to keep rising. Read it beside the growth rate, not alone.

  • Is the buyback buying ownership, or mopping up? 16.3%
    Stock pay, share count unread
    Stock compensation $16M (fiscal 2025), 16.3% of revenue · no repurchases · 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 2 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 · $100M
    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× · 8.66×
    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.

  • 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 $-1.27/share (latest year $-1.63), the averaged base the calculator's gate runs on, and book value is $6.39/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.

Management, ownership & pay

read the proxy →

From the proxy: how much of the business the people running it own, and how they are paid.

  • Insider ownership5.3%

    The stake all directors and executive officers hold together, per the 2026 proxy: skin in the game, the first thing Munger reads.

  • Stock-based compensation$16M

    The slice of the business handed to employees in shares in fiscal 2025, 16.3% 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-DCF

Beta Bionics 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.

The assumptions

Enter a price to run it.

Owner earnings it must reach
Margin the price demands
Owner-earnings margin today−52%

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.
