Gentex Corp.'s net profit margin has exhibited variability over the past eight quarters, ranging from 16.18% to 18.36%. Generally, the company has maintained a healthy net profit margin above 16%, indicating efficient cost management and profitability. However, there was a slight downward trend in the net profit margin from Q1 2022 to Q4 2023, with a peak in Q1 2022 at 19.21% followed by a gradual decline. This trend may suggest potential challenges in maintaining profitability or increasing costs relative to revenue in recent quarters. Further analysis of operating expenses and revenue trends is warranted to understand the factors influencing the fluctuations in Gentex Corp.'s net profit margin.
