Jabil Inc. — AI supply-chain exposure

Jabil is a contract electronics manufacturer — it does not design chips or systems, it builds them for other people. In the AI build-out it has climbed from generic device assembly into the physical guts of the data centre: whole AI servers, the liquid-cooling loops that stop dense racks from cooking themselves, and the optical transceiver modules that shuttle traffic between them. Its purchase of a pluggable-transceiver business gave it a silicon-photonics foothold in 800G optics, one of the links that stitch racks together inside an AI factory.

Its structural hook is breadth without capital intensity — an asset-light model that lets it ride whichever part of the rack hyperscalers over-invest in next, be it cooling, optics, or the server itself. It captures none of the scarcity pricing of a bottleneck component; it earns on execution and scale as a build-partner. The model weights it heavily because it sits across so many physical build steps at once, but as a producer-for-hire its margins are set by its customers, not by a chokepoint it owns.
