AI Summary

6.0
Neutral

PRLB's record growth and expanding CNC/digital-manufacturing adoption support a scalable-margin upside case, but at ~22x EBITDA and 59–67x earnings, investors should wait for sustained margin and earnings upgrades—or a better entry point—rather than underwrite revenue growth alone.
