Key ratios & quality
- PEG ratioi
- 6.60
- Altman Z-Scorei
- 62.27
PEG uses trailing P/E against the 3-year net income growth rate (12.40%/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.
✦ Quant Financial Health how this is computed
Good
- Altman Z-Score is 62.27, above the 3.0 "safe zone" threshold.
- Most reliable for industrial/manufacturing companies; less meaningful for banks, insurers and other financials.
