XOM Historical PE Ratio Notes

— Exxon Mobil Corporation (XOM) is one of the world’s largest publicly traded oil & gas companies, operating across the entire energy value chain, including exploration, production, refining, and marketing of petroleum & petrochemical products. The company’s business is highly sensitive to global commodity prices, chiefly crude oil & natural gas, which fluctuate due to factors like supply & demand dynamics, geopolitical events, and macroeconomic trends. This volatility in earnings makes Exxon Mobil’s historical price-to-earnings (PE) ratio quite variable over different market cycles. During periods of high oil prices, earnings typically surge, which can cause the PE ratio to fall, assuming share price rises more modestly. Conversely, during oil price downturns or global recessions, earnings may contract sharply, often driving the PE ratio higher even if the stock price falls, since “E” in the PE equation can become unusually low. It’s important to contextualize XOM's historical PE ratios within these broader sector & macroeconomic trends as you review charts & tables, recognizing that valuation may reflect not only company-specific performance but also the cyclical nature of the energy sector.

On this page we presented the XOM Historical PE Ratio information for Exxon Mobil' stock. The average XOM 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 25.2. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average XOM historical PE based on this TTM earnings result method is 18.4. Note: any PE calculations resulting in a value exceeding 500 were discarded as not meaningful. Note: any PE calculations involving negative earnings were discarded as not meaningful.

Let's now compare this XOM historical PE result, against the recent PE: when this page was posted on 7/2/2026, the most recent closing price for XOM had been 137.09, and the most recent quarterly earnings result, annualized, was 4.64. Meanwhile, the most recent TTM earnings summed to 6.39. From these numbers, we calculate the recent XOM PE on 7/2/2026 based on annualized quarterly EPS was 29.5. Based on XOM's history, that recent PE is elevated relative to the historical average, with the recent PE 17.1% higher than the historical average PE across our data set for Exxon Mobil. Looking at the recent XOM PE on 7/2/2026 based on TTM EPS, we calculate the ratio at 21.5. Based on XOM's history, that recent PE is elevated relative to the historical average, with the recent PE 16.8% higher than the historical average PE across our Exxon Mobil data set with TTM EPS used in the calculation at each period.

Another interesting XOM historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for XOM, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for XOM, we start with the past four EPS numbers and we first sort them from lowest to highest: 1.16, 1.64, 1.71, and 1.88. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 1.64 and 1.71 — which gives us the median of 1.68. Basically the way to think about this 1.68 number is this: for the trailing four earnings reports, 1.68 marks the "middle ground" number where XOM has reported a value higher than 1.68 half the time, and has reported a value lower than 1.68 half the time. Annualizing that median value then gets us to 6.72/share, which we use as the denominator in our next PE calculation. With 137.09 as the numerator (as of 7/2/2026), the calculation is then 137.09 / 6.72 = 20.4 as the XOM PE ratio as of 7/2/2026, based on that annualized median value we calculated.

For self directed investors doing their due diligence on XOM or any other given stock, valuation analysis for XOM can greatly benefit from studying the past earnings and resulting PE calculations. This exercise can help inform an analysis as to whether the past earnings trajectory and current versus historical PE ratios justify the current stock value.
