WTRG Historical PE Ratio Notes

— Essential Utilities (NYSE: WTRG) is one of the largest publicly traded water, wastewater, and natural gas providers in the U.S., serving residential, commercial, and industrial customers primarily in Pennsylvania, Ohio, North Carolina, and a handful of other states. The company's primary business is highly regulated, with revenues and profits largely determined by rate structures approved by state utility commissions. This regulatory stability, combined with the essential nature of water & gas services, generally leads to steady, predictable earnings that support relatively higher historical P/E ratios compared to less stable sectors. When reviewing historical P/E ratio charts and tables for WTRG, it’s important to consider external factors such as changes in interest rates, the broader market valuation of utility stocks, and one-time adjustments due to acquisitions or regulatory decisions. Periods with lower P/E ratios may reflect market concerns about regulatory challenges or potential earnings headwinds, while higher P/E ratios often correspond to periods of strong, stable earnings or investor preference for defensive sectors. Understanding this relationship between WTRG's regulated business model and its historical P/E trends provides a foundation for assessing valuation over time.

On this page we presented the WTRG Historical PE Ratio information for Essential Utilities' stock. The average WTRG historical PE based on using the annualized quarterly earnings result at each measurement period (for the "E" in the PE calculation; and the closing price on earnings date as the "P") is 26.0. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average WTRG historical PE based on this TTM earnings result method is 23.7.

Let's now compare this WTRG historical PE result, against the recent PE: when this page was posted on 8/10/2026, the most recent closing price for WTRG had been 39.78, and the most recent quarterly earnings result, annualized, was 1.48. Meanwhile, the most recent TTM earnings summed to 1.96. From these numbers, we calculate the recent WTRG PE on 8/10/2026 based on annualized quarterly EPS was 26.9. Based on WTRG's history, that recent PE is elevated relative to the historical average, with the recent PE 3.5% higher than the historical average PE across our data set for Essential Utilities. Looking at the recent WTRG PE on 8/10/2026 based on TTM EPS, we calculate the ratio at 20.3. Based on WTRG's history, that recent PE is low relative to the historical average, with the recent PE 14.3% lower than the average PE across our Essential Utilities data set with TTM EPS used in the calculation at each period.

Another interesting WTRG historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for WTRG, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for WTRG, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.33, 0.37, 0.47, and 0.79. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.37 and 0.47 — which gives us the median of 0.42. Basically the way to think about this 0.42 number is this: for the trailing four earnings reports, 0.42 marks the "middle ground" number where WTRG has reported a value higher than 0.42 half the time, and has reported a value lower than 0.42 half the time. Annualizing that median value then gets us to 1.68/share, which we use as the denominator in our next PE calculation. With 39.78 as the numerator (as of 8/10/2026), the calculation is then 39.78 / 1.68 = 23.7 as the WTRG PE ratio as of 8/10/2026, based on that annualized median value we calculated.
