What is Proto Labs worth?

On an owner-earnings DCF, Proto Labs's most-likely value is about $45 versus a recent price near $94 (52% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$23) with a margin of safety — so the honest verdict here is “Fairly priced — no edge.” Fair value earns its keep only at the extremes, not in the wide middle.

Verdict: Fairly priced — no edge

Owner-earnings fair value · recent price ≈ $94

Fair value (most likely)

$45

Range

$32–$78

No-growth floor

Price

~$94

Price sits in the normal range — fair value isn't actionable here; it earns its keep only when price drops below the no-growth floor, or runs to roughly double the optimistic case.

Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
