Amphenol's demand can experience some seasonality, particularly in certain markets. The company anticipates a potential seasonal decline in the communications networks market, with sales expected to decrease in the low teens range in Q4 2025 due to normal seasonality patterns. However, the company's diversified presence across various end markets helps to mitigate the impact of seasonality in any single market. The revolution in electronics continues to accelerate, creating long-term growth opportunities for Amphenol's high-speed and power interconnect products.
