“Accelerating global deployment of AI-driven data centers and adoption of next-generation IT architecture is driving strong, sustained demand for Amphenol's high-speed, high-value interconnect solutions.

Another View: What Do Market Multiples Suggest?

While the narrative method paints Amphenol as undervalued, our look at its price-to-earnings ratio tells a different story. Amphenol trades at 41.8x earnings, well above both the US Electronic industry average (22.6x) and its fair ratio estimate of 38.8x. Compared to peer averages, however, it still looks less expensive. This wide spread suggests valuation risk and less room for error. Is the share price running ahead of fundamentals, or does the growth story justify the premium?
