WLDN Historical PE Ratio Notes

— Willdan Group, Inc. (WLDN) is an engineering & consulting firm that provides comprehensive energy, engineering, and sustainability services primarily to public agencies, utilities, and private industry clients in the United States. The company is known for its expertise in energy efficiency, infrastructure improvements, and smart city solutions, often managing large-scale projects aimed at increasing energy savings and operational efficiencies for municipalities and utilities. When reviewing historical PE (price-to-earnings) ratios for WLDN, it’s important to understand that the company's earnings can be influenced by cyclical trends in public spending, government infrastructure funding, and the pace of energy transition initiatives. Periods of strong legislative support for energy efficiency or infrastructure modernization may result in higher earnings visibility, often leading to a higher PE ratio assigned by the market. Conversely, delays in government contracts or unpredictable shifts in funding can lead to earnings volatility, which typically pushes the historical PE ratio higher as the company trades at a premium to current earnings in anticipation of future growth or at a discount as earnings drop. As you examine charts of price, earnings, and PE ratios, consider how these external and internal business drivers may have shaped market sentiment about Willdan's growth prospects through different periods.

On this page we presented the WLDN Historical PE Ratio information for Willdan Group' stock. The average WLDN 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 19.6. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average WLDN historical PE based on this TTM earnings result method is 18.5. Note: any PE calculations involving negative earnings were discarded as not meaningful.

Let's now compare this WLDN historical PE result, against the recent PE: when this page was posted on 5/22/2026, the most recent closing price for WLDN had been 93.55, and the most recent quarterly earnings result, annualized, was 3.64. Meanwhile, the most recent TTM earnings summed to 5.19. From these numbers, we calculate the recent WLDN PE on 5/22/2026 based on annualized quarterly EPS was 25.7. Based on WLDN's history, that recent PE is elevated relative to the historical average, with the recent PE 31.1% higher than the historical average PE across our data set for Willdan Group. Looking at the recent WLDN PE on 5/22/2026 based on TTM EPS, we calculate the ratio at 18.0. Based on WLDN's history, that recent PE is low relative to the historical average, with the recent PE 2.7% lower than the average PE across our Willdan Group data set with TTM EPS used in the calculation at each period.

Another interesting WLDN historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for WLDN, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for WLDN, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.91, 1.21, 1.50, and 1.57. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 1.21 and 1.50 — which gives us the median of 1.35. Basically the way to think about this 1.35 number is this: for the trailing four earnings reports, 1.35 marks the "middle ground" number where WLDN has reported a value higher than 1.35 half the time, and has reported a value lower than 1.35 half the time. Annualizing that median value then gets us to 5.4/share, which we use as the denominator in our next PE calculation. With 93.55 as the numerator (as of 5/22/2026), the calculation is then 93.55 / 5.4 = 17.3 as the WLDN PE ratio as of 5/22/2026, based on that annualized median value we calculated.
