On this page we presented the OI Historical PE Ratio information for O-I Glass' stock. The average OI 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 14.6. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average OI historical PE based on this TTM earnings result method is 8.9. Note: any PE calculations involving negative earnings were discarded as not meaningful.

Let's now compare this OI historical PE result, against the recent PE: when this page was posted on 10/8/2026, the most recent closing price for OI had been 6.17, and the most recent quarterly earnings result, annualized, was 0.36. Meanwhile, the most recent TTM earnings summed to 0.82. From these numbers, we calculate the recent OI PE on 10/8/2026 based on annualized quarterly EPS was 17.1. Based on OI'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 O-I Glass. Looking at the recent OI PE on 10/8/2026 based on TTM EPS, we calculate the ratio at 7.5. Based on OI's history, that recent PE is low relative to the historical average, with the recent PE 15.7% lower than the average PE across our O-I Glass data set with TTM EPS used in the calculation at each period.

Another interesting OI historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for OI, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for OI, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.05, 0.09, 0.20, and 0.48. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.09 and 0.20 — which gives us the median of 0.15. Basically the way to think about this 0.15 number is this: for the trailing four earnings reports, 0.15 marks the "middle ground" number where OI has reported a value higher than 0.15 half the time, and has reported a value lower than 0.15 half the time. Annualizing that median value then gets us to 0.6/share, which we use as the denominator in our next PE calculation. With 6.17 as the numerator (as of 10/8/2026), the calculation is then 6.17 / 0.6 = 10.3 as the OI PE ratio as of 10/8/2026, based on that annualized median value we calculated.

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