AGEN Historical PE Ratio Notes

— Agenus Inc. (ticker: AGEN) is a biotechnology company specializing in the discovery & development of immuno-oncology therapies, including next-generation checkpoint inhibitors and cancer vaccines. The company's business model is centered around high-risk, high-reward research & development, with revenue often tied to milestone payments, collaborations, and potential future product sales rather than established, consistent earnings streams. This unique situation frequently leads to highly variable—even negative—earnings, which directly impacts the price-to-earnings (PE) ratio when you examine historical data. Unlike mature companies that exhibit steady earnings and more stable PE ratios, Agenus' historical PE ratio may be erratic or, at times, not meaningful (such as when earnings are negative and the ratio is undefined or not calculable at all). As you analyze charts and tables of AGEN's historical price, earnings, and PE ratios, keep in mind that fluctuations often reflect the inherent uncertainty of biotech development cycles, clinical trial news, and investor sentiment regarding future breakthroughs, rather than predictable profit trends. Understanding this context will help you interpret AGEN's historical valuation properly.

On this page we presented the Agenus Historical PE Ratio information for Agenus' stock. The average AGEN 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 2.2. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average AGEN historical PE based on this TTM earnings result method is 13.6. Note: any PE calculations involving negative earnings were discarded as not meaningful.

Let's now compare this AGEN historical PE result, against the recent PE: when this page was posted on 8/14/2026, the most recent closing price for AGEN had been 7.32, and the most recent quarterly earnings result, annualized, was 4.08. Meanwhile, the most recent TTM earnings summed to 2.576. From these numbers, we calculate the recent AGEN PE on 8/14/2026 based on annualized quarterly EPS was 1.8. Based on AGEN's history, that recent PE is low relative to the historical average, with the recent PE 18.2% lower than the historical average PE across our data set for Agenus. Looking at the recent AGEN PE on 8/14/2026 based on TTM EPS, we calculate the ratio at 2.8. Based on AGEN's history, that recent PE is low relative to the historical average, with the recent PE 79.4% lower than the average PE across our Agenus data set with TTM EPS used in the calculation at each period.

Another interesting AGEN historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for AGEN, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for AGEN, we start with the past four EPS numbers and we first sort them from lowest to highest: -0.37, -0.01, 1.02, and 1.94. We then toss out the highest and lowest result, and then take the average of those two middle numbers — -0.01 and 1.02 — which gives us the median of 0.51. Basically the way to think about this 0.51 number is this: for the trailing four earnings reports, 0.51 marks the "middle ground" number where AGEN has reported a value higher than 0.51 half the time, and has reported a value lower than 0.51 half the time. Annualizing that median value then gets us to 2.04/share, which we use as the denominator in our next PE calculation. With 7.32 as the numerator (as of 8/14/2026), the calculation is then 7.32 / 2.04 = 3.6 as the AGEN PE ratio as of 8/14/2026, based on that annualized median value we calculated.

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