Fundamentals
Valuation and ratings
York Space Systems, Inc. trades at $8.65, which is 101% below the $17.36 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 25 out of 100, which is little in the way of a 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.

Estimates are the published analyst consensus and move often. An earnings date is scheduled, not certain, and a share tends to reprice most violently on the day itself.

Common questions
Is York Space Systems, Inc. (YSS) undervalued?
Against our fair value estimate of $17.36, YSS at $8.65 is 101% 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.
Which funds own YSS?
9 of the institutions we track reported a position in YSS in their most recent SEC 13F filing. A 13F is filed up to 45 days after quarter end, so it tells you what a fund held then, not what it holds now.
