On this page we presented the TDG Historical PE Ratio information for TransDigm Gr' stock. The average TDG 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 29.7. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average TDG historical PE based on this TTM earnings result method is 31.1.

Let's now compare this TDG historical PE result, against the recent PE: when this page was posted on 1/21/2025, the most recent closing price for TDG had been 1358.01, and the most recent quarterly earnings result, annualized, was 39.32. Meanwhile, the most recent TTM earnings summed to 33.98. From these numbers, we calculate the recent TDG PE on 1/21/2025 based on annualized quarterly EPS was 34.5. Based on TDG's history, that recent PE is elevated relative to the historical average, with the recent PE 16.2% higher than the historical average PE across our data set for TransDigm Gr. Looking at the recent TDG PE on 1/21/2025 based on TTM EPS, we calculate the ratio at 40.0. Based on TDG's history, that recent PE is elevated relative to the historical average, with the recent PE 28.6% higher than the historical average PE across our TransDigm Gr data set with TTM EPS used in the calculation at each period.

Another interesting TDG historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for TDG, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for TDG, we start with the past four EPS numbers and we first sort them from lowest to highest: 7.16, 7.99, 9.00, and 9.83. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 7.99 and 9.00 — which gives us the median of 8.50. Basically the way to think about this 8.50 number is this: for the trailing four earnings reports, 8.50 marks the "middle ground" number where TDG has reported a value higher than 8.50 half the time, and has reported a value lower than 8.50 half the time. Annualizing that median value then gets us to 34/share, which we use as the denominator in our next PE calculation. With 1358.01 as the numerator (as of 1/21/2025), the calculation is then 1358.01 / 34 = 39.9 as the TDG PE ratio as of 1/21/2025, based on that annualized median value we calculated.
