Amphenol (APH)

Connectors + interconnect (Amphenol) — high-speed connectors/cables for AI servers/networking

AI exposure 30% — derived from reported segment revenue, not asserted.

Where it sits

Connectivity → Electronics Connectors · figures rebased to Q2 2026, reported 2026-07-29

IT datacom + mobile networks connectors (AI data-center interconnect) + CCS copper/fiber connectivity leads 2 businesses in this sub-tier that together are 78% of revenue, so Electronics Connectors is effectively the whole company rather than one leg of it. The rest is tagged separately: Defense & Government AI at 11%.

Also tagged: emerging in Frontier & Emerging Bets → Defense & Government AI.

Reported segments

• Communications Solutions — 61% of revenue
• Harsh Environment Solutions — 22% of revenue
• Interconnect & Sensor Systems — 17% of revenue

Amphenol (H1 2026 $16.4B sales, +~55% YoY; ~$35B FY2026 run-rate incl. CCS) — connectors/interconnect/sensors. Communications Solutions ~61% (IT datacom = AI data-center interconnect + the CCS copper/fiber acquisition = primary B3 Electronics Connectors; mix jumped from ~45% on AI-datacom growth + CCS). Harsh Environment ~22% (mil-spec/defense connectors = purpose-built B7 Defense tag kept; + industrial). Interconnect & Sensors ~17%. Primary B3 Connectors (the AI-datacom connectors are the growth core).

How the 30% is built

• Communications Solutions — 61% of revenue × 46% AI-driven (disclosed). Mgmt Q2 2026: AI-related revenue at a $10.5-11B annual run rate against ~$35B annualized sales (Q2 $8.76B; Q3 guide $9.3-9.4B) = ~30% of total. IT datacom — which sits inside this segment — was 43% of Q2 sales, +89% USD / +63% organic, with virtually all of the sequential growth from AI products. Putting essentially…
• Harsh Environment Solutions — 22% of revenue × 3% AI-driven (estimate). Estimate — mil-aero/defense and industrial connectors; management attributed this segment's Q2 growth to defense and industrial drivers, not AI
• Interconnect & Sensor Systems — 17% of revenue × 8% AI-driven (estimate). Estimate — sensors and interconnects for industrial/mobile/EV with a modest data-center power and busbar slice; lowered from 10 so the three rows reconcile to the ~30% of total that management actually disclosed

Investment read

Moat. Interconnect breadth, design-win execution and a serial M&A machine, now extended across both copper and optical inside the rack by CCS (FY2026 contribution raised to ~$4.6B sales and $0.30 EPS accretion, from $4.1B and $0.15 at close). Amphenol is one of several qualified suppliers on any given socket — the durability sits in the decentralized operating model and the design-win base, not in per-product exclusivity.

Bottleneck / pricing power. Strong pricing power via design-win lock-in and rising interconnect content per AI server: record 29.8% adjusted operating margin (~28.9% excluding the $80M IEEPA tariff recovery) on 30% organic growth, with two consecutive quarters of record orders at 1.23-1.24x book-to-bill. No longer a quiet compounder — at ~$185B it is a consensus AI holding.
