TTM’s 91% Q2 rise came as investors sought AI bottlenecks, fund says

Granahan’s Focused Growth Strategy said TTM Technologies shares rose 91% in Q2 2026 as investors sought AI bottlenecks beyond chipmakers. It cited TTM’s high-layer-count AI-networking boards and rising results and estimates, but cut its holding to below-average size.

TTM makes advanced printed circuit boards for data-center networking, aerospace and defense. The company added 211 basis points to the portfolio in Q2; the strategy returned 37.3%, versus 25.7% for the Russell 2000 Growth benchmark.
