MDU Historical PE Ratio Notes

— MDU Resources Group, Inc. (MDU) is a diversified energy and infrastructure company with primary operations in regulated utility services, construction materials, and construction services. The company's segments include electric & natural gas utilities, pipeline & midstream operations, and a substantial construction materials & services business, which has made MDU one of the leading suppliers of construction aggregates in the U.S. Over time, the company's business mix has evolved, influencing its risk profile and growth prospects—factors that the stock market incorporates when assigning MDU its historical price/earnings (PE) ratio. Regulatory stability in its utility units typically supports more predictable earnings, leading to higher PE ratios in certain periods, while more cyclical construction segments can add volatility, potentially depressing the PE ratio during economic downturns or industry headwinds. Major corporate actions, such as the 2023 spinoff of its Knife River construction materials business, can also impact both earnings and perceived risk, causing shifts in the company's valuation multiples. As you review historical PE charts & tables, note how changes in MDU's earnings mix, macroeconomic cycles, and strategic initiatives have influenced both investor expectations and the company's relative valuation over time.

On this page we presented the MDU Historical PE Ratio information for MDU Resources Gr' stock. The average MDU 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 MDU historical PE based on this TTM earnings result method is 8.6.

Let's now compare this MDU historical PE result, against the recent PE: when this page was posted on 9/11/2026, the most recent closing price for MDU had been 19.20, and the most recent quarterly earnings result, annualized, was 0.4. Meanwhile, the most recent TTM earnings summed to 0.95. From these numbers, we calculate the recent MDU PE on 9/11/2026 based on annualized quarterly EPS was 48.0. Based on MDU's history, that recent PE is elevated relative to the historical average, with the recent PE 332.4% higher than the historical average PE across our data set for MDU Resources Gr. Looking at the recent MDU PE on 9/11/2026 based on TTM EPS, we calculate the ratio at 20.2. Based on MDU's history, that recent PE is elevated relative to the historical average, with the recent PE 134.9% higher than the historical average PE across our MDU Resources Gr data set with TTM EPS used in the calculation at each period.

Another interesting MDU historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for MDU, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for MDU, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.09, 0.10, 0.37, and 0.39. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.10 and 0.37 — which gives us the median of 0.23. Basically the way to think about this 0.23 number is this: for the trailing four earnings reports, 0.23 marks the "middle ground" number where MDU has reported a value higher than 0.23 half the time, and has reported a value lower than 0.23 half the time. Annualizing that median value then gets us to 0.92/share, which we use as the denominator in our next PE calculation. With 19.20 as the numerator (as of 9/11/2026), the calculation is then 19.20 / 0.92 = 20.9 as the MDU PE ratio as of 9/11/2026, based on that annualized median value we calculated.

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