Is BBNX undervalued? Our fair value estimate
Beta Bionics, Inc. · Healthcare · NGM
How we got here
The estimate is computed from BBNX's reported fundamentals, with a growth assumption that is deliberately capped: small changes to an uncapped growth or terminal assumption can justify any price, and a number that can justify anything means nothing. These are the inputs the model holds for BBNX today; the exact method, and where it goes wrong, is on the methodology page.
The trailing growth rate informs the growth assumption, which the model caps deliberately: uncapped growth assumptions can justify any price.
Wall Street's published earnings growth forecast, used as context for the capped growth assumption, never swallowed whole.
Margins tell the model how much of each unit of revenue survives as profit, and how much room there is for that to erode.
Persistent high returns on capital are what a moat looks like in the accounts, and they feed the moat score alongside the valuation.
A volatility measure against the wider market. A jumpier share earns a larger discount for risk, which lowers the estimate.
Leverage haircuts the estimate: debt claims cash before shareholders do, and it turns bad years into dangerous ones.
Wall Street's number, next to ours
The mean analyst price target for BBNX is USD19.80 across 10 analysts, which implies +11.1% from the current price. Our estimate is USD6.92. They answer different questions: an analyst target is a 12-month price prediction averaged across banks; ours is a model's view of what the business is worth, with every assumption published. When they disagree, at least one of us is wrong.
The belief gap: what growth this price asks you to believe
Run our DCF backwards and every price becomes a growth assumption. One axis compares them: today's market price, the entry prices implied by super investors' 13F filings, the mean analyst target, and the growth our own model funds. The gap between the market's marker and the cohort's markers is the growth you are being asked to believe that informed buyers did not need.
Today's price asks you to believe about 28.9% annual cash-flow growth. Farallon Capital Management's Q1 2026 entry only needed about 13.9%. Our model funds 5.0%.
Farallon Capital Management's Q1 2026 filing implies an average entry near $10.02, which implied about 13.9% annual growth under our model.
Point72 Asset Management's Q1 2026 filing implies an average entry near $10.02, which implied about 13.9% annual growth under our model.
Millennium Management's Q4 2025 filing implies an average entry near $30.47, which implied a growth rate outside our model's 0-30% band under our model (low confidence).
Two Sigma Investments's Q4 2025 filing implies an average entry near $30.47, which implied a growth rate outside our model's 0-30% band under our model (low confidence).
Entry prices are filing-implied averages (reported position value divided by reported shares for the quarter a position was opened or materially increased), not actual cost bases; 13Fs lag by up to 45 days. How the Belief Gap is computed.

The same model, run on the highest-rated names in the same sector. A gap to fair value is only comparable when the method behind it is identical, which here it is.
