Amphenol
Summary
What they do:
World's second-largest manufacturer of interconnect products — the high-speed connectors, cable assemblies, and power connectors that physically link GPUs, servers, switches, and power distribution systems inside data centers. Also serves automotive, defense, mobile devices, and industrial markets.
Why they matter:
Every AI server rack requires hundreds of high-speed connectors operating at 112Gbps+ per lane for GPU-to-GPU, server-to-switch, and power distribution connections. Amphenol's IT Datacom segment grew 110% organically in FY2025 on AI-related demand — one of the highest growth rates anywhere in the AI supply chain.
Recent performance:
FY2025 revenue $23.1B (+52% YoY, record). Q4 revenue $6.4B (+49% YoY). IT Datacom 38% of sales with 110% organic growth. Q1 2026 guided $6.9-7.0B (+43-45% YoY). Stock ~$151, market cap ~$186B.
Our Verdict
The interconnect backbone of the AI data center — 110% organic IT Datacom growth confirms Amphenol is a direct, high-conviction beneficiary of every dollar spent on AI infrastructure, and the diversified end-market portfolio provides downside protection that pure-play AI infrastructure companies lack.

If NVIDIA makes the brain of the AI data center and Arista makes the nervous system, Amphenol makes the connective tissue — the physical connectors and cable assemblies that link every component inside a data center. Every GPU connects to a motherboard through a high-speed connector. Every server connects to a network switch through a cable assembly. Every power distribution unit connects to a rack through a power connector. Amphenol manufactures all of these.
The company operates through two segments: Harsh Environment Solutions (~35% of revenue) serving defense, automotive, industrial, and mobile networks; and Communications Solutions (~65% of revenue) serving IT Datacom, broadband, and mobile devices. The IT Datacom sub-segment within Communications Solutions is where the AI growth lives — and it's been extraordinary. IT Datacom represented 38% of total company sales in Q4 2025, growing 110% organically (excluding acquisitions), driven by insatiable demand for high-speed and power interconnect products in AI data centers.
Amphenol's growth in FY2025 was amplified by the acquisition of CommScope's Connectivity and Cable Solutions (CCS) business, which closed in early 2025 and added approximately $3.5B in annual revenue plus copper and fiber cable capabilities. Including CCS, FY2025 revenue reached $23.1B — up 52% from FY2024's $15.2B. Even excluding acquisitions, organic growth was approximately 25%+, driven by AI-related IT Datacom demand.
The company is headquartered in Wallingford, Connecticut, with approximately 95,000 employees and over 130 manufacturing locations globally. Amphenol's operational model is distinctive: highly decentralized with each business unit operating semi-autonomously, which enables rapid product development and customer responsiveness. The company has a long history of disciplined capital allocation — free cash flow of $4.4B in FY2025 represented 103% of net income.
Q4 2025 was a record quarter: revenue $6.4B (+49% YoY), beating consensus of $6.15B. Adjusted EPS $0.97, beating consensus of $0.92. Management guided Q1 2026 to $6.9-7.0B (+43-45% YoY), including $900M from CCS, and adjusted EPS of $0.91-$0.93.
Supply Chain Dependencies
The Catch
Amphenol's IT Datacom segment grew 110% organically in FY2025 — one of the most extraordinary growth rates in the AI supply chain. But 110% growth from a $8-9B annual run-rate business cannot sustain indefinitely. The inevitable deceleration — even to a still-impressive 30-40% — will cause the market to question whether Amphenol deserves its 38x forward P/E, which is 40-50% above its historical 25-30x range. The CCS acquisition adds revenue but at lower margins than Amphenol's core, creating a dilution risk to the profitability profile. And connectors, while critical, follow industry standards that enable multi-sourcing — TE Connectivity, Molex, and Foxconn can all supply alternatives, limiting Amphenol's pricing power in the highest-volume categories.
If They Win
If AI data center buildout sustains through 2028, connector content per rack continues growing with each networking speed generation (112G → 224G → next), CCS integration creates a complete interconnect platform that hyperscalers prefer for supply chain simplicity, and defense + automotive provide parallel growth engines, then Amphenol becomes the wiring of the AI economy — the company whose connectors are inside every server rack, every network switch, every power distribution unit in every AI data center on earth. Revenue compounds to $40B+ by 2028, margins improve as manufacturing scale and CCS synergies compound, and the current $186B market cap looks reasonable against a $5B+ annual earnings power scenario.
