Fundamentals
Valuation and ratings
Butler National Corporation trades at $4.03, which is 164% below the $10.65 our fair value estimate puts on the business. On that measure alone it screens as undervalued, though a valuation model is an argument rather than a measurement, and the market is frequently right about why something is cheap.
Our moat model scores it 75 out of 100, which is a wide moat. A moat is a structural reason competitors cannot take the profits away, and it matters more to a long holding period than any single quarter's numbers do.
It changes hands at 14.2 times earnings. Be careful reading that in isolation: for a cyclical business a low P/E arrives at the top of the cycle, when profits are peaking and about to fall, which is exactly when the shares look cheapest and are not.

Common questions
Is Butler National Corporation (BUKS) undervalued?
Against our fair value estimate of $10.65, BUKS at $4.03 is 164% below fair value. That is one model's answer, not a recommendation. It is built from normalized earning power with growth capped deliberately low, which understates companies whose value is mostly future growth.
What is BUKS's P/E ratio?
BUKS trades at 14.2 times earnings. A low P/E is not automatically cheap: on a cyclical company it is usually a warning that earnings are at a peak.
