Is JBI undervalued? Our fair value estimate
Janus International Group, Inc. · Industrials · NYQ
How we got here
The estimate is computed from JBI'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 JBI today; the exact method, and where it goes wrong, is on the methodology page.
The starting point is earnings power: what the business earns per share, and what the market currently pays for each unit of it.
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 JBI is USD7.70 across 5 analysts, which implies +46.1% from the current price. Our estimate is USD4.11. 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 10.9% annual cash-flow growth. First Eagle Investment Management's Q4 2025 entry underwrote a higher 16.2%. Our model funds 5.0%. The mean analyst target implies 20.4%.
First Eagle Investment Management's Q4 2025 filing implies an average entry near $6.54, which implied about 16.2% annual growth under our model (low confidence).
Aqr Capital Management's Q1 2026 filing implies an average entry near $5.15, which implied about 10.3% annual growth under our model.
Citadel Advisors's Q4 2025 filing implies an average entry near $6.54, which implied about 16.2% annual growth under our model (low confidence).
D. E. Shaw &'s Q1 2026 filing implies an average entry near $5.15, which implied about 10.3% annual growth under our model.
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.
