Is Amphenol Corporation stock undervalued or overvalued?
Valuing Amphenol Corporation stock is incredibly difficult, and any metric has to be viewed as part of a bigger picture of Amphenol Corporation's overall performance. However, analysts commonly use some key metrics to help gauge the value of a stock.
Amphenol Corporation's P/E ratio
Amphenol Corporation's current share price divided by its per-share earnings (EPS) over a 12-month period gives a "trailing price/earnings ratio" of roughly 47x. In other words, Amphenol Corporation shares trade at around 47x recent earnings.
That's relatively high compared to, say, the trailing 12-month P/E ratio for the NASDAQ 100 at the end of 2019 (27.29). The high P/E ratio could mean that investors are optimistic about the outlook for the shares or simply that they're over-valued.
Amphenol Corporation's PEG ratio

The PEG ratio provides a broader view than just the P/E ratio, as it gives more insight into Amphenol Corporation's future profitability. By accounting for growth, it could also help you if you're comparing the share prices of multiple high-growth companies.

Amphenol Corporation share dividends
Dividend payout ratio: 25.51% of net profits
Recently Amphenol Corporation has paid out, on average, around 0% of net profits as dividends. That has enabled analysts to estimate a "forward annual dividend yield" of 0% of the current stock value. This means that over a year, based on recent payouts (which are sadly no guarantee of future payouts), Amphenol Corporation shareholders could enjoy a 0% return on their shares, in the form of dividend payments. In Amphenol Corporation's case, that would currently equate to about $0.66 per share.
While Amphenol Corporation's payout ratio might seem fairly standard, it's worth remembering that Amphenol Corporation may be investing much of the rest of its net profits in future growth.
Amphenol Corporation's most recent dividend payout was on 6 January 2026. The latest dividend was paid out to all shareholders who bought their shares by 15 December 2025 (the "ex-dividend date").
Have Amphenol Corporation's shares ever split?
Amphenol Corporation's shares were
split on a 2:1 basis on 11 June 2024
. So if you had owned 1 share the day before before the split, the next day you'd have owned 2 shares. This wouldn't directly have changed the overall worth of your Amphenol Corporation shares – just the quantity. However, indirectly, the new 50% lower share price could have impacted the market appetite for Amphenol Corporation shares which in turn could have impacted Amphenol Corporation's share price.
Amphenol Corporation share price volatility
