Amphenol (APH) is back in focus after the company approved its third quarter 2026 dividend of $0.25 per share, or $0.125 post split. This has reinforced attention on its recent share price gains.

At a share price of $159.57, Amphenol has slipped 6.61% on a 1-day basis and 4.58% over the past week. Its 90-day share price return of 29.68% and 1-year total shareholder return of 46.08% point to momentum that investors are now weighing against richer expectations as growth in revenue, earnings, free cash flow and AI or data center exposure attracts more attention.

If Amphenol’s recent move has you thinking about other potential opportunities linked to digital infrastructure, it may be worth checking a screener of 56 AI infrastructure stocks. These stocks can help you broaden your watchlist beyond a single sector focus.

Amphenol’s sharp run and recent pullback can look like a clean read on strong revenue, earnings and cash flow. It can also reflect investors crowding into an AI and data center story. Which is the bigger driver of today’s valuation?

Most Popular Narrative: 19.4% Undervalued

Compared with Amphenol’s last close at $159.57, the most widely followed narrative sets a higher fair value and leans heavily on its AI and data center exposure to justify the gap.

Accelerating global deployment of AI-driven data centers and adoption of next-generation IT architecture is driving strong, sustained demand for Amphenol's high-speed, high-value interconnect solutions, as evidenced by exceptional growth in IT datacom revenue and continued multi-quarter customer engagement, this is expected to support further top-line growth and maintain higher incremental margins.

Want to see what this narrative assumes about Amphenol’s revenue mix, earnings trajectory and future margin structure? The fair value hinges on a specific growth and profitability path that is very different to a typical hardware supplier story.

Result: Fair Value of $198.06 (UNDERVALUED)

However, the bullish Amphenol story could be tested if AI and data center demand proves more volatile than expected or if ongoing high capex squeezes future free cash flow.
