On this page we presented the O PE Ratio History information for Realty Income' stock. The average O PE ratio history 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 17.8. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average O PE ratio history based on this TTM earnings result method is 18.2.

Let's now compare this O PE ratio history result, against the recent PE: when this page was posted on 1/21/2025, the most recent closing price for O had been 55.26, and the most recent quarterly earnings result, annualized, was 4.2. Meanwhile, the most recent TTM earnings summed to 4.15. From these numbers, we calculate the recent O PE on 1/21/2025 based on annualized quarterly EPS was 13.2. Based on O's history, that recent PE is low relative to the historical average, with the recent PE 25.8% lower than the historical average PE across our data set for Realty Income. Looking at the recent O PE on 1/21/2025 based on TTM EPS, we calculate the ratio at 13.3. Based on O's history, that recent PE is low relative to the historical average, with the recent PE 26.9% lower than the average PE across our Realty Income data set with TTM EPS used in the calculation at each period.

Another interesting O PE ratio history calculation we look at is to take the median earnings per share of the last four quarters for O, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for O, we start with the past four EPS numbers and we first sort them from lowest to highest: 1.01, 1.03, 1.05, and 1.06. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 1.03 and 1.05 — which gives us the median of 1.04. Basically the way to think about this 1.04 number is this: for the trailing four earnings reports, 1.04 marks the "middle ground" number where O has reported a value higher than 1.04 half the time, and has reported a value lower than 1.04 half the time. Annualizing that median value then gets us to 4.16/share, which we use as the denominator in our next PE calculation. With 55.26 as the numerator (as of 1/21/2025), the calculation is then 55.26 / 4.16 = 13.3 as the O PE ratio as of 1/21/2025, based on that annualized median value we calculated.
