On this page we presented the ORLY Historical PE Ratio information for O'Reilly Automotive' stock. The average ORLY 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 1.5. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average ORLY historical PE based on this TTM earnings result method is 1.6.

Let's now compare this ORLY historical PE result, against the recent PE: when this page was posted on 6/17/2025, the most recent closing price for ORLY had been 88.80, and the most recent quarterly earnings result, annualized, was 37.4. Meanwhile, the most recent TTM earnings summed to 40.81. From these numbers, we calculate the recent ORLY PE on 6/17/2025 based on annualized quarterly EPS was 2.4. Based on ORLY's history, that recent PE is elevated relative to the historical average, with the recent PE 60.0% higher than the historical average PE across our data set for O'Reilly Automotive. Looking at the recent ORLY PE on 6/17/2025 based on TTM EPS, we calculate the ratio at 2.2. Based on ORLY's history, that recent PE is elevated relative to the historical average, with the recent PE 37.5% higher than the historical average PE across our O'Reilly Automotive data set with TTM EPS used in the calculation at each period.

Another interesting ORLY historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for ORLY, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for ORLY, we start with the past four EPS numbers and we first sort them from lowest to highest: 9.35, 9.50, 10.55, and 11.41. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 9.50 and 10.55 — which gives us the median of 10.03. Basically the way to think about this 10.03 number is this: for the trailing four earnings reports, 10.03 marks the "middle ground" number where ORLY has reported a value higher than 10.03 half the time, and has reported a value lower than 10.03 half the time. Annualizing that median value then gets us to 40.12/share, which we use as the denominator in our next PE calculation. With 88.80 as the numerator (as of 6/17/2025), the calculation is then 88.80 / 40.12 = 2.2 as the ORLY PE ratio as of 6/17/2025, based on that annualized median value we calculated.
