What the score is made of
Each factor is half a curve over reported figures and half a rank among the other Utilities companies (momentum is judged against fixed thresholds only), and the five are blended by weight. The score is where that blend places it in the S&P 500. It describes the last filing and the current price. It is not a forecast.

The financials
Revenue growth
Is the business growing? Yes
| Last 12 months | +8.2% |
|---|---|
| Over 5 years | +7.5% a year |
| FY2025 revenue | $29.6B (+10%) |
Free cash flow
Is it generating real cash? No, it is burning cash
| FY2025 free cash flow | −$2.9B |
|---|---|
| Of revenue | −10% |
| Of profit | −68% |
Profit margins
Is profitability improving? Holding steady
| Gross margin | 40% |
|---|---|
| Operating margin | 26% |
| Net margin, FY24 → FY25 → now | 16.4% → 14.7% → 16.7% |
Debt vs. cash
Is the balance sheet healthy? Stretched
| Cash | $1.6B |
|---|---|
| Long-term debt | $65.6B |
| Net debt | $64.0B |
| Years to repay | 6.7 yrs |
Valuation
Is the stock price reasonable? Yes, about fair
| P/E | 21.4× |
|---|---|
| Fair P/E for its growth | 25× |
| Forward P/E | 19.3× |
| EV / EBITDA | 13.3× |
At 21.4× earnings it trades close to the 25× that 7% a year of growth plus a 4.0% dividend would justify. As a utility it is judged on earnings alone: it borrows to build, so its free cash flow says little about its price.
