Amphenol (APH) is back in focus after reporting record Q1 2026 results, issuing strong Q2 guidance on sales and EPS, and seeing analysts lift earnings estimates in response to these updates.

Despite the recent 7-day share price return of a 7.23% decline and a softer 1-day move, Amphenol’s 1-year total shareholder return of 70.75% and very large 5-year total shareholder return of 338.07% point to strong longer term momentum. The latest earnings beat, Q2 guidance, buybacks and euro senior notes offering are all feeding into how investors are reassessing growth potential and risk.

With Amphenol trading at $136.62, showing a 1-year total return of 70.75% and sitting roughly 33% below the average analyst price target of $181.72, is this still a compelling entry point, or is the stock already pricing in future growth?

Price-to-Earnings of 37.6x: Is it justified?

Amphenol’s shares last closed at $136.62, which equates to a P/E of 37.6x, leaving the stock priced above the broader US Electronic industry and above the level suggested by our DCF estimate of $117.86.

The P/E ratio compares today’s share price to the company’s earnings per share. A higher P/E often reflects higher expectations for future earnings growth. In Amphenol’s case, earnings are forecast to grow 18.3% per year and revenue 12.9% per year, and recent earnings growth of 70.9% over the past year has been much stronger than the Electronic industry’s 11.1%.

Relative to the US Electronic industry average P/E of 27.7x, Amphenol looks expensive. However, it sits below the peer average of 52.3x and below an estimated fair P/E of 43.8x that the market could gravitate toward if current growth and profitability expectations hold.

Result: Price-to-Earnings of 37.6x (ABOUT RIGHT)

However, there are still real risks to keep in mind, including any slowdown in key end markets and execution missteps across its three operating segments.

Another view using the SWS DCF model

While a 37.6x P/E looks roughly fair compared with the 43.8x fair ratio, the SWS DCF model tells a different story. On that view, Amphenol at $136.62 sits above an estimated fair value of $117.86, which can mean less margin for error if growth expectations change.
