✦ Quant Financial Health how this is computed

Good

Altman Z-Score is 6.14, above the 3.0 "safe zone" threshold.
Most reliable for industrial/manufacturing companies; less meaningful for banks, insurers and other financials.

Revenue annual, last 8 years

Latest year +19.14% YoY

Margins

Gross margin: 35.97%
Operating margin: 14.58%
Net margin: 10.21%

Key ratios & quality

Enterprise value: 147.63B
PEG ratio: 11.33
Altman Z-Score: 6.14

PEG uses trailing P/E against the 3-year net income growth rate (6.64%/yr) since forward earnings estimates aren't available here, so this is not a "forward PEG." Altman Z-Score below ~1.8 suggests financial distress risk, above ~3.0 suggests low risk; the model is most reliable for industrial/manufacturing companies and less meaningful for banks and other financial firms.
