NWE Historical PE Ratio Notes
— NorthWestern Energy Group (ticker: NWE) is a regulated utility serving electric & natural gas customers across Montana, South Dakota, and Nebraska. The company generates, transmits, and distributes electricity, while also supplying and delivering natural gas. NWE's revenues primarily depend on regulated rates set by state utility commissions, providing a measure of stability but also limiting the potential for rapid earnings growth. This regulatory environment and focus on essential services mean that NorthWestern's historical price-to-earnings (PE) ratio often reflects its perceived safety & predictability compared to less-regulated energy companies. As you review NWE's historical PE ratio charts & tables, you'll notice that during periods of economic uncertainty or market stress, investors may gravitate towards defensive stocks like NWE, potentially supporting a higher PE ratio. Conversely, in times of heightened risk appetite or changing regulatory landscapes, the PE ratio may contract. It's important to consider that NWE's earnings growth is typically modest due to regulatory constraints, and the stock is often valued for its dividend & stable cash flows rather than aggressive expansion. This overall profile drives the patterns you'll see in the historical PE ratio data.
How should the NWE historical PE ratio be determined?
Realizing that PE stands for Price to Earnings ratio, we need two values to compute it: stock price and earnings per share. The stock price at any given date is a known historical value, but what about the earnings number to use?
✔️Accepted answer:
There are a number of different approaches when it comes to calculating a historical PE ratio for a company like NorthWestern Energy Group. We like to take our measurements on each of the past quarterly earnings reports. That only leaves the question of whether the earnings number at that quarterly report should be used on an annualized basis, or some other method. We approach this question using three different methods, on this NWE Historical PE Ratio page.
What is the average historical PE for NWE based on annualized quarterly earnings?
As we look back through earnings history, what is the resulting PE calculation if at each measurement period we use that quarter's earnings result annualized?
✔️Accepted answer:
The NWE historical PE ratio using the annualized quarterly earnings method works out to 20.6.
What is the average historical PE for NWE based on trailing twelve month earnings?
As we look back through earnings history, what is the resulting PE calculation if at each measurement period we use the trailing twelve months combined earnings result in the calculation?
✔️Accepted answer:
The NWE historical PE ratio using the TTM earnings method works out to 17.5.
What is the average historical PE for NWE based on median TTM earnings?
As we look back through earnings history, what is the resulting PE calculation if at each measurement period we use the median earnings over the trailing twelve months and annualize that median result in the calculation?
✔️Accepted answer:
The NWE historical PE ratio using the annualized median TTM earnings method works out to 3.92.
On this page we presented the
NWE Historical PE Ratio information for NorthWestern Energy Group' stock.
The average NWE 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 20.6. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average NWE historical PE based on this TTM earnings result method is 17.5. Note: any PE calculations involving negative earnings were discarded as not meaningful.
Let's now compare this NWE historical PE result, against the recent PE: when this page was posted on 10/5/2026, the most recent closing price for NWE had been 68.76, and the most recent quarterly earnings result, annualized, was 2. Meanwhile, the most recent TTM earnings summed to 3.77. From these numbers, we calculate the recent NWE PE on 10/5/2026 based on annualized quarterly EPS was 34.4. Based on NWE's history, that recent PE is elevated relative to the historical average, with the recent PE 67.0% higher than the historical average PE across our data set for NorthWestern Energy Group. Looking at the recent NWE PE on 10/5/2026 based on TTM EPS, we calculate the ratio at 18.2. Based on NWE's history, that recent PE is elevated relative to the historical average, with the recent PE 4.0% higher than the historical average PE across our NorthWestern Energy Group data set with TTM EPS used in the calculation at each period.
Another interesting NWE historical PE Ratio calculation we look at is to take the
median earnings per share of the last four quarters for NWE, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for NWE, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.50, 0.79, 1.17, and 1.31. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.79 and 1.17 — which gives us the median of 0.98. Basically the way to think about this 0.98 number is this: for the trailing four earnings reports, 0.98 marks the "middle ground" number where NWE has reported a value
higher than 0.98 half the time, and has reported a value
lower than 0.98 half the time. Annualizing that median value then gets us to 3.92/share, which we use as the denominator in our next PE calculation. With 68.76 as the numerator (as of 10/5/2026), the calculation is then 68.76 / 3.92 =
17.5 as the NWE PE ratio as of 10/5/2026, based on that annualized median value we calculated.
