Silver Lake completes 51% acquisition stake in FPGA firm Altera

17 September 2025

Investment firm Silver Lake has completed its 51% acquisition of field programmable gate array (FPGA) vendor Altera Corp.

The deal, which former parent company Intel Corp. announced in April of 2025, establishes Altera (once again) as the largest pure-play FPGA player globally. Before getting acquired by Intel in 2015, Altera was one of two FPGA companies that led the globe in programmable logic. Xilinx, the other FPGA firm, was acquired by Intel rival AMD in 2020.

Intel will retain a 49% stake in Altera.

Altera said it will continue to provide:

  • System-on-chips
  • FPGA semiconductors
  • Software tools
  • Development kits
  • IP and design services

Altera said after the acquisition, Silver Lake’s resources will help the company expand into sectors like industrial automation, audio/video, robotics, aerospace, defense, data centers, telecom and edge AI.
