- SummaryPhysical bottlenecks in power and cooling are expanding capex allocations beyond merchant silicon to hardware specialists. Modine, Astera Labs, and Vertiv provide thermal management, high-speed connectivity, and electrical infrastructure. Equipment suppliers have experienced valuation pullbacks from 2026 highs despite sustained hyperscale buildouts.
