On this page we presented the AAMI Historical PE Ratio information for Acadian Asset Management' stock. The average AAMI 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 11.1. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average AAMI historical PE based on this TTM earnings result method is 10.6.

Let's now compare this AAMI historical PE result, against the recent PE: when this page was posted on 12/2/2025, the most recent closing price for AAMI had been 43.65, and the most recent quarterly earnings result, annualized, was 3.04. Meanwhile, the most recent TTM earnings summed to 3.24. From these numbers, we calculate the recent AAMI PE on 12/2/2025 based on annualized quarterly EPS was 14.4. Based on AAMI's history, that recent PE is elevated relative to the historical average, with the recent PE 29.7% higher than the historical average PE across our data set for Acadian Asset Management. Looking at the recent AAMI PE on 12/2/2025 based on TTM EPS, we calculate the ratio at 13.5. Based on AAMI's history, that recent PE is elevated relative to the historical average, with the recent PE 27.4% higher than the historical average PE across our Acadian Asset Management data set with TTM EPS used in the calculation at each period.

Another interesting AAMI historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for AAMI, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for AAMI, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.54, 0.64, 0.76, and 1.30. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.64 and 0.76 — which gives us the median of 0.70. Basically the way to think about this 0.70 number is this: for the trailing four earnings reports, 0.70 marks the "middle ground" number where AAMI has reported a value higher than 0.70 half the time, and has reported a value lower than 0.70 half the time. Annualizing that median value then gets us to 2.8/share, which we use as the denominator in our next PE calculation. With 43.65 as the numerator (as of 12/2/2025), the calculation is then 43.65 / 2.8 = 15.6 as the AAMI PE ratio as of 12/2/2025, based on that annualized median value we calculated.
