Hammond Power Solutions Inc. — AI supply-chain exposure

Hammond Power Solutions makes dry-type transformers and power-quality equipment, the gear that steps voltage up and down and conditions power as it moves from the grid into buildings and machines. It sits in the infrastructure layer as a supplier tied to transformer availability, a North American manufacturer positioned directly in the path of data-center electrification.

Its hook is a genuine bottleneck. Transformers have become one of the scarcest links in the build-out, with long lead times and limited manufacturing capacity, and every data-center campus needs many of them before it can energize a single rack. That scarcity hands makers like Hammond unusual pricing power and a long order backlog. The model places its centrality at moderate: not glamorous, but structurally exposed to the same electrification wave driving grid and data-center demand, a picks-and-shovels position on power rather than compute.
