On this page we presented the ALRM Historical PE Ratio information for Alarm.com Holdings' stock. The average ALRM 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 35.6. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average ALRM historical PE based on this TTM earnings result method is 36.2.

Let's now compare this ALRM historical PE result, against the recent PE: when this page was posted on 4/21/2025, the most recent closing price for ALRM had been 49.34, and the most recent quarterly earnings result, annualized, was 2.32. Meanwhile, the most recent TTM earnings summed to 2.28. From these numbers, we calculate the recent ALRM PE on 4/21/2025 based on annualized quarterly EPS was 21.3. Based on ALRM's history, that recent PE is low relative to the historical average, with the recent PE 40.2% lower than the historical average PE across our data set for Alarm.com Holdings. Looking at the recent ALRM PE on 4/21/2025 based on TTM EPS, we calculate the ratio at 21.6. Based on ALRM's history, that recent PE is low relative to the historical average, with the recent PE 40.3% lower than the average PE across our Alarm.com Holdings data set with TTM EPS used in the calculation at each period.

Another interesting ALRM historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for ALRM, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for ALRM, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.50, 0.58, 0.58, and 0.62. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.58 and 0.58 — which gives us the median of 0.58. Basically the way to think about this 0.58 number is this: for the trailing four earnings reports, 0.58 marks the "middle ground" number where ALRM has reported a value higher than 0.58 half the time, and has reported a value lower than 0.58 half the time. Annualizing that median value then gets us to 2.32/share, which we use as the denominator in our next PE calculation. With 49.34 as the numerator (as of 4/21/2025), the calculation is then 49.34 / 2.32 = 21.3 as the ALRM PE ratio as of 4/21/2025, based on that annualized median value we calculated.
