Amphenol Corporation has emerged as a key beneficiary of AI infrastructure investment, with its stock gaining 51.77% over the past 52 weeks as data center revenue—now one-third of total revenue—surged 81% year-over-year in the March 2026 quarter.
The company manufactures connectors and sensors critical to AI data centers, which demand higher-performance components than conventional cloud infrastructure.
Investors remain focused on whether this exceptional growth trajectory can be sustained as market expectations remain elevated.
What happened
Aoris International Fund highlighted Amphenol Corporation (NYSE:APH), a manufacturer of electrical and fiber optic connectors, in its Q2 2026 investor letter. The stock closed at $165.75 per share on August 13, 2026, with a one-month return of 9.62% and a 52-week gain of 51.77%; the company has a market capitalization of $204.37 billion.
Why it matters
Data center infrastructure now accounts for one-third of Amphenol's revenue, and AI data centers require more high-performance connectors and cables than conventional cloud infrastructure. In the March 2026 quarter, the company's data center revenue grew 81% versus the prior year, positioning it as a direct beneficiary of the AI infrastructure buildout that drove international equity markets higher.
What to watch
Investors are concerned about the sustainability of Amphenol's current data center revenue growth. While major AI infrastructure companies continue to report demand exceeding supply, market expectations are high and the stock will be sensitive to any signs of slowing demand.

Amphenol's prominence in Aoris International Fund's Q2 2026 letter reflects a broader trend in international equity markets during that period: exceptional gains among AI infrastructure companies, particularly semiconductor producers and data center suppliers. The fund's portfolio underperformed its benchmark during the quarter—Class A (Unhedged) returned 5.7% after fees, 8.1% below its benchmark—partly due to exposure concerns in enterprise software and data companies challenged by AI. Yet Amphenol illustrates the other side of the AI opportunity: while the fund avoided cyclical sectors like banks and commodity producers due to low growth prospects, it identified companies with meaningful incremental AI-driven tailwinds.
The 81% year-over-year data center revenue growth in the March 2026 quarter is the concrete figure underpinning Amphenol's 51.77% stock gain over 52 weeks. The company's connectors and sensors are not discretionary add-ons but essential infrastructure for AI workloads, where power and data transfer constraints are far tighter than in conventional cloud deployments. This structural advantage has allowed Amphenol to capture pricing power and volume share simultaneously—a rare combination in infrastructure supply.
