AAP Historical PE Ratio Notes

— Advance Auto Parts (ticker: AAP) is one of the largest automotive aftermarket parts providers in the U.S., serving both professional repair shops & DIY customers. The company operates thousands of stores under several banners, supplying replacement parts, accessories, batteries, & maintenance items for cars and light trucks. When researching AAP's historical price-to-earnings (PE) ratio, keep in mind that this ratio is heavily influenced by two main factors: the stock price and the company's reported earnings. In years when Advance Auto Parts grew earnings steadily or benefited from industry tailwinds (such as higher vehicle age & increased demand for repairs), its PE ratio often rose as investors anticipated further growth. However, periods of operational challenges, increased competition, or supply chain issues may have led to stagnating or declining earnings, pressuring the PE ratio downward even if the stock price was steady. Broader economic cycles can also impact AAP's earnings and thus its historical PE, as can management's strategic moves (like acquisitions or changes in store count). As you analyze historical data, consider these industry & company-specific factors for context on why the market valued AAP a certain way at different points in time.

On this page we presented the AAP Historical PE Ratio information for Advance Auto Parts' stock. The average AAP 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 19.5. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average AAP historical PE based on this TTM earnings result method is 29.6. 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 AAP historical PE result, against the recent PE: when this page was posted on 9/8/2026, the most recent closing price for AAP had been 42.56, and the most recent quarterly earnings result, annualized, was 4.12. Meanwhile, the most recent TTM earnings summed to 3.58. From these numbers, we calculate the recent AAP PE on 9/8/2026 based on annualized quarterly EPS was 10.3. Based on AAP's history, that recent PE is low relative to the historical average, with the recent PE 47.2% lower than the historical average PE across our data set for Advance Auto Parts. Looking at the recent AAP PE on 9/8/2026 based on TTM EPS, we calculate the ratio at 11.9. Based on AAP's history, that recent PE is low relative to the historical average, with the recent PE 59.8% lower than the average PE across our Advance Auto Parts data set with TTM EPS used in the calculation at each period.

Another interesting AAP historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for AAP, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for AAP, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.77, 0.86, 0.92, and 1.03. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.86 and 0.92 — which gives us the median of 0.89. Basically the way to think about this 0.89 number is this: for the trailing four earnings reports, 0.89 marks the "middle ground" number where AAP has reported a value higher than 0.89 half the time, and has reported a value lower than 0.89 half the time. Annualizing that median value then gets us to 3.56/share, which we use as the denominator in our next PE calculation. With 42.56 as the numerator (as of 9/8/2026), the calculation is then 42.56 / 3.56 = 12.0 as the AAP PE ratio as of 9/8/2026, based on that annualized median value we calculated.

For self directed investors doing their due diligence on AAP or any other given stock, valuation analysis for AAP 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.
