Analysis
Proto Labs Inc (PRLB) currently trades at $79.53, while our model-based Fair Value estimate is $26.42, implying the stock looks roughly 201.0% overvalued today. The Quality Score stands at 74/100 (solid quality), in the Industrials sector. Bull case: the DCF Models group reads highest at a median of $30.60 per share, and 0 of the 26 models we run sit above the $79.53 price. Bear case: the Earnings-Based group reads lowest at $7.79, and 26 of the 26 models stay below the price. Evidence for this calculation is high.
Over the trailing twelve months, Proto Labs Inc generated revenue of $546M at a net margin of 4.7%. Revenue grew 10.4% year over year. It earns a return on equity of 3.8%. The balance sheet holds a net cash position of $106M. Fundamentals as of Sep 5, 2026
Our scenario range runs from $19.81 (bear case) to $33.01 (bull case); at $79.53, 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 4% below its 52-week high and 107% above its 52-week low, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at −58% fair-value upside, at −67%, PRLB screens richer than that median.
Fair Value models
This estimate rests on fiscal year 2025 figures, and about 8 months have passed since. In that time the company retained roughly $0.7202 per share, which is 2.7 % of the fair value. The fair value deliberately does not add this in: the models value reported figures, not a projection.
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted, family-balanced 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. Every input is real reported data, nothing guessed.
All 26 models by family
Widest divergence: DCF Models ($30.60) versus Dividend Discount ($2.06). Highest evidence: FCF DCF (80).

Quality Score breakdown
Of which business quality 72 · Market factors (momentum, volatility) 69
Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
