CEG Historical PE Ratio Notes

— Constellation Energy (ticker symbol CEG) is one of the leading energy companies in the United States, specializing in the generation and supply of clean energy, including nuclear, solar, wind, and natural gas sources. CEG operates the nation’s largest fleet of zero-carbon nuclear plants, and its business model is focused on providing wholesale and retail electricity to commercial, industrial, and residential customers. This heavy emphasis on stable, long-term contracted sales & regulated market segments tends to make CEG’s earnings relatively steady compared to more volatile, commodity-exposed energy peers. When you review CEG’s historical price, earnings per share, and P/E ratio charts, keep in mind that the market often rewards or penalizes the company based on trends in electricity demand, regulatory changes, carbon reduction policies, & energy price movements. Periods of regulatory support for clean energy initiatives, for example, can fuel higher valuations, as reflected in an expanding P/E ratio, while unexpected changes in power prices, fuel costs, or policy uncertainty may compress this ratio. Understanding CEG’s business fundamentals can therefore provide you useful context as you analyze how investor sentiment and earnings expectations have shaped its historical P/E ratio over time.

On this page we presented the Constellation Energy Historical PE Ratio information for Constellation Energy' stock. The average CEG 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 46.3. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average CEG historical PE based on this TTM earnings result method is 34.1. Note: any PE calculations involving negative earnings were discarded as not meaningful.

Let's now compare this CEG historical PE result, against the recent PE: when this page was posted on 4/2/2026, the most recent closing price for CEG had been 272.82, and the most recent quarterly earnings result, annualized, was 9.2. Meanwhile, the most recent TTM earnings summed to 9.39. From these numbers, we calculate the recent CEG PE on 4/2/2026 based on annualized quarterly EPS was 29.7. Based on CEG's history, that recent PE is low relative to the historical average, with the recent PE 35.9% lower than the historical average PE across our data set for Constellation Energy. Looking at the recent CEG PE on 4/2/2026 based on TTM EPS, we calculate the ratio at 29.1. Based on CEG's history, that recent PE is low relative to the historical average, with the recent PE 14.7% lower than the average PE across our Constellation Energy data set with TTM EPS used in the calculation at each period.

Another interesting CEG historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for CEG, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for CEG, we start with the past four EPS numbers and we first sort them from lowest to highest: 1.91, 2.14, 2.30, and 3.04. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 2.14 and 2.30 — which gives us the median of 2.22. Basically the way to think about this 2.22 number is this: for the trailing four earnings reports, 2.22 marks the "middle ground" number where CEG has reported a value higher than 2.22 half the time, and has reported a value lower than 2.22 half the time. Annualizing that median value then gets us to 8.88/share, which we use as the denominator in our next PE calculation. With 272.82 as the numerator (as of 4/2/2026), the calculation is then 272.82 / 8.88 = 30.7 as the CEG PE ratio as of 4/2/2026, based on that annualized median value we calculated.

For self directed investors doing their due diligence on CEG or any other given stock, valuation analysis for CEG can greatly benefit from studying the past earnings and resulting PE calculations.
