ATRC Historical PE Ratio Notes

— AtriCure, Inc. (ATRC) is a medical device company focused on developing innovative technologies for the treatment of atrial fibrillation (“AF”) and related conditions. The company specializes in cardiac ablation devices and surgical solutions that help physicians reduce or eliminate irregular heart rhythms, with its products used in minimally invasive as well as open-heart procedures. When analyzing ATRC’s historical P/E ratio, it’s important to remember that as a growth-oriented medtech company, AtriCure has historically reinvested heavily in research, development, and global expansion. This often results in limited or negative net earnings, leading to high or even undefined P/E ratios during periods of aggressive growth or major investments. Market participants may have given AtriCure a premium valuation, betting on future profitability driven by a large addressable market and strong revenue growth. When reviewing historical price, earnings, and P/E ratio data, consider the context: spikes or drops in P/E often reflect swings in reported earnings tied to clinical trial expenses, regulatory milestones, or shifts in investor expectations about long-term growth, rather than short-term changes in fundamental earning power.

On this page we presented the ATRC Historical PE Ratio information for AtriCure' stock. The average ATRC 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 62.9. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average ATRC historical PE based on this TTM earnings result method is 143.5. 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 ATRC historical PE result, against the recent PE: when this page was posted on 7/31/2026, the most recent closing price for ATRC had been 37.76, and the most recent quarterly earnings result, annualized, was 0.72. Meanwhile, the most recent TTM earnings summed to 0.23. From these numbers, we calculate the recent ATRC PE on 7/31/2026 based on annualized quarterly EPS was 52.4. Based on ATRC's history, that recent PE is low relative to the historical average, with the recent PE 16.7% lower than the historical average PE across our data set for AtriCure. Looking at the recent ATRC PE on 7/31/2026 based on TTM EPS, we calculate the ratio at 164.2. Based on ATRC's history, that recent PE is elevated relative to the historical average, with the recent PE 14.4% higher than the historical average PE across our AtriCure data set with TTM EPS used in the calculation at each period.

Another interesting ATRC historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for ATRC, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for ATRC, we start with the past four EPS numbers and we first sort them from lowest to highest: -0.01, 0.00, 0.06, and 0.18. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.00 and 0.06 — which gives us the median of 0.03. Basically the way to think about this 0.03 number is this: for the trailing four earnings reports, 0.03 marks the "middle ground" number where ATRC has reported a value higher than 0.03 half the time, and has reported a value lower than 0.03 half the time. Annualizing that median value then gets us to 0.12/share, which we use as the denominator in our next PE calculation. With 37.76 as the numerator (as of 7/31/2026), the calculation is then 37.76 / 0.12 = 314.7 as the ATRC PE ratio as of 7/31/2026, based on that annualized median value we calculated.

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