Artisan Mid Cap Fund on Lattice Semiconductor Corporation

Thesis

Lattice specializes in low-power field-programmable gate arrays for data centers, communications and industrial systems. FPGA revenue increased 62% year over year, reflecting broad strength in these end markets. Its acquisition of AMI adds platform firmware and data center management software to its hardware, positioning Lattice as a fuller AI infrastructure management-and-control supplier. The manager expects an accelerated profit cycle and added shares following a market rotation out of data center hardware.

“We expect the acquisition to accelerate Lattice’s profit cycle”
Artisan Mid Cap Fund — September 2026 Monthly Commentary

Key risks

  • Investor rotation away from data center hardware enablers has already hurt the shares.
  • Integration of AMI and delivery of an expanded management platform may fall short of expectations.
  • The exceptionally strong recent FPGA growth rate may not persist across end markets.
