Approach 1: Amphenol Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what Amphenol might be worth today by projecting its future cash flows and then discounting those back to a present value. It is essentially a way to turn a stream of expected future cash into a single current figure.

For Amphenol, the model uses a 2 Stage Free Cash Flow to Equity approach. The most recent last twelve months Free Cash Flow is about $4.69b. Analyst estimates and subsequent extrapolations suggest Free Cash Flow projections that reach $8.80b by 2030, with specific forecasts and extensions provided for each year in between.

Simply Wall St aggregates these projected cash flows, discounts them using its own assumptions, and arrives at an estimated intrinsic value of $116.27 per share for Amphenol. Compared with the recent share price of $165.15, the DCF output suggests the stock is around 42.0% above this model’s estimate of fair value.

Approach 2: Amphenol Price vs Earnings

For a profitable company like Amphenol, the P/E ratio is a useful way to relate what you pay for the stock to the earnings it generates. It helps you see how many dollars investors are currently willing to pay for each dollar of earnings.

What counts as a “normal” or “fair” P/E ratio usually depends on how fast earnings are expected to grow and how risky those earnings are. Higher expected growth or lower perceived risk can support a higher P/E, while lower growth expectations or higher risk often line up with a lower P/E.

Amphenol currently trades on a P/E of 45.50x. That sits above the Electronic industry average P/E of 31.32x and below the peer group average of 99.12x. Simply Wall St’s Fair Ratio for Amphenol is 45.84x, which is its proprietary view of what the P/E “should” be after considering factors such as earnings growth profile, industry, profit margin, market cap and company specific risks.

This Fair Ratio can be more informative than a simple industry or peer comparison because it adjusts for those company specific characteristics rather than assuming all stocks deserve similar multiples. With Amphenol’s actual P/E of 45.50x sitting very close to the Fair Ratio of 45.84x, the stock appears broadly in line with this metric.
