Analog Devices completes $1.35 billion purchase of Pleasanton’s Alif Semiconductor
The all-cash deal, with up to $200 million more contingent, adds AI-native microcontrollers for on-device “physical intelligence.”
Analog Devices said Tuesday it finished buying Alif Semiconductor, a Pleasanton company that makes AI-ready microcontrollers — tiny computers that sit inside gadgets and run on-device AI without sending data to the cloud.
ADI agreed Sept. 9 to pay $1.35 billion in cash up front, and may pay up to $200 million more in contingent payments, subject to the deal terms. No stock swap was part of the announced price. The boards of both companies approved the deal; it closed after customary conditions, including U.S. antitrust waiting-period rules.
Alif, founded to build “fusion processors” that mix neural chips with radios and power control, already ships to consumer and industrial customers. ADI, based in Wilmington, Massachusetts, with more than $11 billion in fiscal 2025 revenue, said Alif extends its sensing and signal chips into edge AI for robots, wearables, factories and data centers.
Neither company disclosed layoffs or a per-share breakdown for Alif’s private holders in the close notice.
