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.

Valuation

Is the stock price reasonable? Yes, about fair

P/E21.4×
Fair P/E for its growth25×
Forward P/E19.3×
EV / EBITDA13.3×

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.
