The next major AI supply-chain bottleneck is data center construction and skilled labor. In the US, Sterling Infrastructure is uniquely positioned because it is the only company that has successfully internalized its construction workforce, while 40% of the construction labor pool is expected to retire by 2031. Its data center contracts are structured so that hyperscalers buy materials directly, and savings from accelerated schedules or reduced material use are split 70-30 with the builder, creating powerful profit momentum. This gives Sterling an exceptional edge as the data center buildout accelerates.
