Approach 1: Amphenol Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company might be worth by projecting its future cash flows and then discounting those amounts back to today. It is essentially asking what all those future dollars are worth in present terms.

For Amphenol, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flow projections in US$. The latest twelve month free cash flow is about $4.69b. Analyst estimates and subsequent extrapolations point to projected free cash flow of $11.70b in 2035, with interim years such as 2030 projected at $8.80b. Simply Wall St only uses direct analyst inputs for the earlier years, then extends the series using its own assumptions for later years.

Pulling all of those discounted cash flows together, the DCF model arrives at an estimated intrinsic value of about $126.81 per share. Compared with the recent share price of $147.27, this implies the stock is around 16.1% overvalued based on this single framework.

Result: OVERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Amphenol may be overvalued by 16.1%. Discover 51 high quality undervalued stocks or create your own screener to find better value opportunities.

Approach 2: Amphenol Price vs Earnings

For a profitable company like Amphenol, the P/E ratio is a useful way to think about what you are paying for each dollar of earnings. Higher growth expectations or lower perceived risk can justify a higher P/E, while slower expected growth or higher risk usually line up with a lower, more conservative multiple.

Amphenol currently trades on a P/E of 40.55x. That sits above the Electronic industry average P/E of 28.20x, but below the peer group average of 53.69x. To put this into context, Simply Wall St also calculates a proprietary “Fair Ratio” of 35.02x. This is the P/E level that might be expected given factors such as Amphenol’s earnings profile, industry, profit margins, market cap and identified risks.

This Fair Ratio can be more informative than a simple comparison with peers or the broader industry because it adjusts for company specific attributes like growth, risk and profitability, rather than assuming one size fits all. Comparing Amphenol’s current P/E of 40.55x with the Fair Ratio of 35.02x indicates that the shares are pricing in a richer multiple than this framework implies.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Amphenol Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives on Simply Wall St let you attach your own story about Amphenol to the numbers by linking assumptions about future revenue, earnings and margins to a fair value, then comparing that fair value with the current share price to decide whether the stock looks attractive or expensive. All of this happens within an easy Community tool that millions of investors use. Each Narrative updates automatically as new earnings or news arrive. One investor might back a higher fair value such as US$205.24 based on confidence in AI data center content and acquisitions, while another might anchor to a lower fair value like US$135.68 that places more weight on margin pressure, competition and execution risk.

For Amphenol however we'll make it really easy for you with previews of two leading Amphenol Narratives:

These give you two clear, numbers based stories, one leaning optimistic on AI and margin strength, the other more cautious on technology shifts and competition. Reading both side by side can help you decide which assumptions feel closer to your own view.

Fair value: US$178.39

Implied discount to this fair value based on the last close of US$147.27: about 17%.

Analyst revenue growth assumption used in this narrative: 17.22% a year.

• Supports a view that AI driven data centers, greater electronic content in autos and industrials, and acquisitions across RF, aerospace and defense contribute to a larger revenue base and higher margins over time.
• Assumes profit margins move from 17.2% to 20.8%, with pricing power and a higher value product mix helping earnings reach about US$8.7b, and a P/E of 34x on those earnings.
• Highlights risks around heavy capex for AI capacity, acquisition integration, and exposure to fast moving tech end markets, so the case rests on those investments continuing to pay off.

Fair value: US$135.68

Implied premium to this fair value based on the last close of US$147.27: about 9%.

Bear case revenue growth assumption used in this narrative: 16.99% a year.

• Describes a scenario where wireless and contactless technologies, commoditisation of connectors and cables, and tougher pricing from lower cost rivals reduce Amphenol's margins and pricing power.
• Incorporates higher costs from supply chain reshoring, regulation and ESG requirements, along with heavy ongoing R&D and capex that weigh on free cash flow.
• Still recognises exposure to long term tech trends, but assumes that by 2029 earnings of about US$6.9b and a 32.3x P/E multiple support a fair value closer to US$135.68 rather than current pricing.

If you want to see how other investors are joining the dots between these numbers and their own expectations, you can read the full narratives, compare the inputs, then adjust the sliders to match your view of Amphenol's growth, margins and risk profile before deciding what feels reasonable for you.
