ABB — AI supply-chain exposure

ABB is a Swiss electrification and automation giant whose switchgear, uninterruptible power supplies and medium-voltage equipment sit inside the power rooms of data centers worldwide. It makes neither chips nor servers; it makes the gear that takes grid power and delivers it, cleanly and reliably, to the racks. The model classes it as a Producer across the power-delivery chain.

Its structural hook is that every GPU cluster is only as usable as the electrical infrastructure feeding it, and AI's rising power density strains exactly the equipment ABB supplies. As campuses scale, demand for switchgear, transformers and UPS systems tightens and lead times stretch. The model places it here because this gear is unglamorous but hard to substitute and slow to manufacture — a quiet chokepoint between the grid and the accelerator that only a handful of electrical majors can dominate.
