In the latest reporting period of Q1'26, Amphenol (APH) reported a Sales Margin (ROS) of 24.19%. This represents a sequential decrease from the 27.47% recorded in Q4'25, following a period of peak profitability. The overall trend from Q2'23 to Q1'26 reflects a general expansion in profitability, with the ROS rising from an initial 20.50% to a high of 27.64% in Q3'25. While the data shows a notable dip in Q2'24 to 19.84%, the subsequent recovery was robust, although the recent decline in Q1'26 suggests a potential cooling of margins after the strong growth seen throughout FY2025.
