YSS · US
Fair value as of: Jul 14, 2026
From 1 valuation models · updated 27 days ago
Share price −45.7% over the past month.
Below-average quality, and screening another 62% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case ($6.54). The favourable scenario is already priced in.
- Weak quality (42/100) and above fair value at the same time, the margin of safety is missing on both counts.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- A fairly wide model range ($3.27 to $6.54) leaves room in how you read the outcome.

Analysis
York Space Systems, Inc (YSS) currently trades at $11.41, while our model-based Fair Value estimate is $4.38, implying the stock looks roughly 61.6% overvalued today. The Quality Score stands at 42/100 (below-average quality), in the Industrials sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: low).
Over the trailing twelve months, York Space Systems, Inc generated revenue of $396M at a net margin of -47.4%. Revenue grew 9.5% year over year. It earns a return on equity of -9.1%. Net debt stands at $12.6M. Fundamentals as of Jul 14, 2026
Our scenario range runs from $3.27 (bear case) to $6.54 (bull case); at $11.41, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 74% below its 52-week high, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -59% fair-value upside, at -62%, YSS screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
