COHR Historical PE Ratio Notes

— Coherent Corp. (COHR), formerly known as II-VI Incorporated, is a global leader in engineered materials, lasers, and photonic solutions used across numerous industries, including communications, industrial manufacturing, precision instrumentation, aerospace & defense, and life sciences. The company's product portfolio features photonic devices, laser systems, and optical components that enable innovation in fast-growing tech areas like 5G, electric vehicles, cloud computing, and medical imaging. Because Coherent is deeply tied to leading-edge technology cycles and broad macro trends, its earnings can be influenced by fluctuating demand from these end markets, changes in capital expenditure by major customers, and overall global economic conditions. Investors should note that the company's price/earnings (PE) ratio historically reflects both the volatility of its earnings due to these cyclical dynamics, and the market's assessment of its future growth prospects. Periods of high PE ratios may indicate optimism about anticipated growth tied to new tech cycles or product launches, while lower PE ratios could reflect either weaker earnings or skepticism about near-term demand. As you review COHR's historical PE ratio charts & tables, consider how these broader themes and specific industry cycles have driven investor sentiment and valuation over time.

On this page we presented the Coherent Historical PE Ratio information for Coherent' stock. The average COHR 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 12.2. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average COHR historical PE based on this TTM earnings result method is 12.6.

Let's now compare this COHR historical PE result, against the recent PE: when this page was posted on 3/6/2026, the most recent closing price for COHR had been 235.72, and the most recent quarterly earnings result, annualized, was 5.16. Meanwhile, the most recent TTM earnings summed to 4.36. From these numbers, we calculate the recent COHR PE on 3/6/2026 based on annualized quarterly EPS was 45.7. Based on COHR's history, that recent PE is elevated relative to the historical average, with the recent PE 274.6% higher than the historical average PE across our data set for Coherent. Looking at the recent COHR PE on 3/6/2026 based on TTM EPS, we calculate the ratio at 54.1. Based on COHR's history, that recent PE is elevated relative to the historical average, with the recent PE 329.4% higher than the historical average PE across our Coherent data set with TTM EPS used in the calculation at each period.

Another interesting COHR historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for COHR, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for COHR, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.91, 1.00, 1.16, and 1.29. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 1.00 and 1.16 — which gives us the median of 1.08. Basically the way to think about this 1.08 number is this: for the trailing four earnings reports, 1.08 marks the "middle ground" number where COHR has reported a value higher than 1.08 half the time, and has reported a value lower than 1.08 half the time. Annualizing that median value then gets us to 4.32/share, which we use as the denominator in our next PE calculation. With 235.72 as the numerator (as of 3/6/2026), the calculation is then 235.72 / 4.32 = 54.6 as the COHR PE ratio as of 3/6/2026, based on that annualized median value we calculated.

For self directed investors doing their due diligence on COHR or any other given stock, valuation analysis for COHR can greatly benefit from studying the past earnings and resulting PE calculations.
