GNTX Historical PE Ratio Notes

— Gentex Corporation (GNTX) is a technology-driven company primarily known for designing & manufacturing high-tech auto-dimming rearview mirrors, as well as electronic features for the global automotive industry. GNTX is also involved in commercial smoke alarms and dimmable windows for aerospace customers, but its core business is focused on supplying automakers with advanced vision & electronics systems that improve driver safety and convenience. When assessing GNTX's historical price-to-earnings (PE) ratio, it's important to understand that the company has historically benefited from long-term supply agreements, innovation-driven demand, and strong relationships with automakers worldwide. Because automotive cycles and consumer technology adoption affect earnings, periods of rapid technological deployment (such as mirror-integrated cameras or sensors) may result in higher market expectations, which can expand the PE ratio. Conversely, during automotive downturns or tech slowdowns, GNTX's earnings can be pressured, often compressing the PE. Historically, Gentex has maintained solid profitability & margins, supporting higher-than-average PE ratios compared to cyclical automakers or lower-tech suppliers, reflecting the market's confidence in ongoing innovation and recurring revenue streams. As you review GNTX's historical price, earnings, and PE charts, keep in mind how new product cycles & auto industry trends have shaped market sentiment and valuations over time.

On this page we presented the GNTX Historical PE Ratio information for Gentex' stock. The average GNTX 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 21.8. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average GNTX historical PE based on this TTM earnings result method is 17.2.

Let's now compare this GNTX historical PE result, against the recent PE: when this page was posted on 5/19/2026, the most recent closing price for GNTX had been 22.67, and the most recent quarterly earnings result, annualized, was 1.92. Meanwhile, the most recent TTM earnings summed to 1.84. From these numbers, we calculate the recent GNTX PE on 5/19/2026 based on annualized quarterly EPS was 11.8. Based on GNTX's history, that recent PE is low relative to the historical average, with the recent PE 45.9% lower than the historical average PE across our data set for Gentex. Looking at the recent GNTX PE on 5/19/2026 based on TTM EPS, we calculate the ratio at 12.3. Based on GNTX's history, that recent PE is low relative to the historical average, with the recent PE 28.5% lower than the average PE across our Gentex data set with TTM EPS used in the calculation at each period.

Another interesting GNTX historical PE Ratio calculation we look at is to take the median earnings per share of the last four quarters for GNTX, and then annualize the resulting value... with that annualized number then being used in the PE calculation. To walk through this math for GNTX, we start with the past four EPS numbers and we first sort them from lowest to highest: 0.43, 0.46, 0.47, and 0.48. We then toss out the highest and lowest result, and then take the average of those two middle numbers — 0.46 and 0.47 — which gives us the median of 0.46. Basically the way to think about this 0.46 number is this: for the trailing four earnings reports, 0.46 marks the "middle ground" number where GNTX has reported a value higher than 0.46 half the time, and has reported a value lower than 0.46 half the time. Annualizing that median value then gets us to 1.84/share, which we use as the denominator in our next PE calculation. With 22.67 as the numerator (as of 5/19/2026), the calculation is then 22.67 / 1.84 = 12.3 as the GNTX PE ratio as of 5/19/2026, based on that annualized median value we calculated.
