TTM Technologies, Inc. — AI supply-chain exposure

TTM Technologies is the largest North American maker of printed circuit boards — the layered substrates onto which chips, connectors and components are mounted. The brief places it as a supplier into host compute, furnishing advanced boards for data-center networking and AI compute alongside a substantial aerospace and defense business. As accelerators and high-speed switches proliferate, the boards carrying their signals have to get denser, faster and lower-loss.

The structural hook is signal integrity. AI systems push data between chips at speeds where the board itself becomes a bottleneck, demanding high-layer-count, low-loss PCBs that few suppliers can make reliably at volume. That pulls TTM up the complexity curve into higher-value work, while its defense franchise adds a stable, less cyclical base. The model assigns a modest weight because a PCB is one enabling component among many, but its exposure sharpens as data-center interconnect gets harder and more content-rich.
