Amphenol (APH)
Industrial / Componentes electrónicos
Amphenol is the global leader in connectors and electronic interconnection, with a proven growth model (recurring M&A + structural AI demand in data centers) that took TTM revenue to $29,000 million (+54% year over year) and operating margin to 27%; at $158 the market already recognizes part of this quality but It trades at a real discount to value, though short of the required margin of safety., with an expected 5-year annual return of +13%.

The essentials
- TTM revenue of $29,012 million (+54.2% year over year), driven by AI demand in data centers (IT/datacom segment +$4,594 million in 2025) and by an active acquisition program (Andrew in 2025, CommScope for $10,500 million in January 2026)
- TTM operating margin of 27.0% (vs 20.7% in FY2024), with return on invested capital of ~20.9% —exceptional band— on a capital base of $29,000 million that already incorporates the goodwill from recent acquisitions
- More leveraged balance sheet after CommScope: total debt of $18,811 million against cash and equivalents of $5,419 million (net debt/TTM EBITDA ≈1.4×); projected net interest nearly doubles in 2026 versus 2025
Intrinsic value — two valuation methods
Total return at 5 years: 13.1%/year = 12.4% appreciation + 0.7% dividend. The target price ($284) is ex-dividend; the $7 in dividends collected over 5 years are added separately.
By both methods, the value today (DCF $210 · Multiples $234) exceeds the market price ($158).
Pillars of the analysis
The verdict — today vs 5 years
Today — fairly valued: at $158 trades ~32.5% below its value discounted to today (~$234); the discount is positive but does not reach the margin of safety we require (≥38%).
At 5 years — Infravalorado: the target price ($284) plus dividends yield above the required average return (10%) — the business compounds.
The bridge: the return at 5 years exceeds the risk-free rate (4.5%) — but the discount does not reach the required margin of safety (≥38%). To require a 15% annual return, it would need to be bought at ~$146.
Thesis
The business
Amphenol is a compounder of proven quality: return on invested capital of ~20.9% (exceptional band), a wide and stable moat (design-in, scale, certifications), and an M&A machine that has historically been the growth engine. AI demand in data centers adds an additional structural tailwind on top of that already solid business.
The valuation
It is valued by EV/EBIT on the consolidated business (industrial archetype, 12×-18× band). With a terminal EBIT projected over a five-year deceleration path from the current 54% toward a durable ~10%, and an exit multiple of 15.5× reflecting the quality of the business, the base-case 5-year value is approximately $284 per share, implying a +13% annual return at the market price.
The margin of safety
At $158 per share, It trades at a real discount to value, though short of the required margin of safety.. The verdict arises from the expected total return (+13%) against the method's thresholds (4%/10%/15%), and the Undervalued reflects that a good part —not all— of the business's quality is already in the price after the strong rally driven by the AI narrative.
What to watch
The key disconfirmer is CommScope integration: if net interest (which nearly doubles in 2026) or integration costs erode margin more than modeled, or if AI demand in data centers slows sooner than expected, the base case loses support. Also watch the tax dispute in China (a $100 million charge already recorded, exposure range up to $300 million) and the concentration of long-lived assets in that country.
