Amphenol Corp - Class A (APH) Valuation

GoodMoat Analysis

Based on data as of March 26, 2026

Amphenol appears unfavourable from a strict value investing perspective, trading at a minimal discount to its fair value estimate with a high P/E multiple. The stock lacks a meaningful margin of safety and is priced for near-perfect execution of its recent high growth rate.

Read full analysis
Based on the GoodMoat framework, the valuation assessment for Amphenol is unfavourable. The current price of $128.73 is essentially at parity with the GoodMoat Target of $129.88, resulting in a negligible margin of safety of less than 1%. This falls far short of the framework's 'Favourable' threshold of a 20-40% margin of safety and is even below the 'Marginal' band of 10-20%. The stock's P/E of 36.9x is significantly elevated, especially when considering the sector's average P/E is typically in the 20-30x range. While the company's impressive 49.1% YoY revenue growth can partially justify a premium, the P/E is high relative to its own historical norms and demands sustained, exceptional growth to be reasonable. The low Free Cash Flow Yield of 2.8% (implying a high P/FCF multiple) further supports the view that the stock is fully valued. For a value investor seeking a margin of safety, the current price offers no discount to the estimated intrinsic value and embeds high growth expectations, making the risk/reward profile unattractive.
