✦ Quant Financial Health how this is computed

Good

Altman Z-Score is 3.55, 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 +11.78% YoY

Margins

Gross margin: 33.21%
Operating margin: 14.10%
Net margin: 8.95%

Key ratios & quality

Enterprise value: 30.69B
PEG ratio: 15.11
Altman Z-Score: 3.55

PEG uses trailing P/E against the 3-year net income growth rate (1.60%/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.
