26% of the score, 28% here after data gaps
Proto Labs, Inc. is valued at 49x its operating profit before acquisition amortisation (EBITA), including debt: past the 25 times where this criterion gives nothing.
18% of the score, 20% here after data gaps
Over 7 years the business earned 2.3% a year after tax on the capital it uses.
16% of the score, 17% here after data gaps
No operating profit over the period, so nothing was earned to reinvest.
14% of the score, 15% here after data gaps
How management spends the money: shares bought back or issued, and whether assets grow faster than the business they serve.
12% of the score, 13% here after data gaps
Today's operating margin of 6.6% is 0.83x its normal 7.9%: below its usual level, with room to recover. Normal is half the 10 year median, half the last four years, so a margin that has held is not taken for a peak.
Taken out: its 8% is shared by the others
No debt or interest figures on file.
6% of the score, 7% here after data gaps
Whether the reported profit arrives as cash, and whether the accounts show the usual signs of stretching.
Each criterion earns 0 to 100 points on the scale drawn under it, and the RyuScore is their average weighted 26, 18, 16, 14, 12, 8 and 6. Scales bend in the company's favour between their ends, so an ordinary figure is never already near zero. For PRLB, balance sheet could not be measured from the filings, so it is taken out and the remaining weights scale up.
Built from the company's annual and quarterly filings with the SEC and today's share price. Banks, insurers and property trusts are not scored: their debt is their raw material, so these yardsticks mean something else there. Figures as of 2026-06-30, latest annual report FY2025.
