On this page we presented the PTLO Historical PE Ratio information for Portillos' stock. The average PTLO 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 43.7. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average PTLO historical PE based on this TTM earnings result method is 40.7. Note: any PE calculations resulting in a value exceeding 500 were discarded as not meaningful. Note: any PE calculations involving negative earnings were discarded as not meaningful.

Let's now compare this PTLO historical PE result, against the recent PE: when this page was posted on 9/11/2026, the most recent closing price for PTLO had been 4.09, and the most recent quarterly earnings result, annualized, was 0.36. Meanwhile, the most recent TTM earnings summed to 0.18. From these numbers, we calculate the recent PTLO PE on 9/11/2026 based on annualized quarterly EPS was 11.4. Based on PTLO's history, that recent PE is low relative to the historical average, with the recent PE 73.9% lower than the historical average PE across our data set for Portillos. Looking at the recent PTLO PE on 9/11/2026 based on TTM EPS, we calculate the ratio at 22.7. Based on PTLO's history, that recent PE is low relative to the historical average, with the recent PE 44.2% lower than the average PE across our Portillos data set with TTM EPS used in the calculation at each period.

Another interesting PTLO historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for PTLO, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for PTLO, we start with the past four EPS numbers and we first sort them from lowest to highest: -0.01, 0.02, 0.08, and 0.09. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.02 and 0.08 — which gives us the median of 0.05. Basically the way to think about this 0.05 number is this: for the trailing four earnings reports, 0.05 marks the "middle ground" number where PTLO has reported a value higher than 0.05 half the time, and has reported a value lower than 0.05 half the time. Annualizing that median value then gets us to 0.2/share, which we use as the denominator in our next PE calculation. With 4.09 as the numerator (as of 9/11/2026), the calculation is then 4.09 / 0.2 = 20.4 as the PTLO PE ratio as of 9/11/2026, based on that annualized median value we calculated.

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