Analog Devices to Acquire Empower Semiconductor for $1.5 Billion to Strengthen AI Power Management

Deal aims to tackle power delivery constraints in AI processors; closing expected in second half of 2026 pending regulatory sign-off

By Caleb Monroe ADI

Analog Devices said it will buy Empower Semiconductor for about $1.5 billion in cash to bolster its portfolio in AI-focused power management. The transaction, which is subject to regulatory approvals, is slated to close in the second half of 2026. Empower’s leadership will remain in place to continue work on integrated voltage regulator technology within Analog Devices.

Key Points

  • Analog Devices will acquire Empower Semiconductor for about $1.5 billion in cash to expand its AI-focused power management offerings.
  • The deal is expected to close in the second half of 2026 and is subject to regulatory approvals, creating a defined timeline and approval risk for realization of benefits.
  • Post-closing, Empower CEO Tim Phillips will continue to lead integrated voltage regulator technology efforts at Analog Devices; PJT Partners and Barclays are financial advisors to Analog Devices and Empower, respectively.

Analog Devices announced plans to acquire Empower Semiconductor for approximately $1.5 billion in cash, a move the company says will expand its suite of power management products aimed at AI and other compute-intensive workloads.

Company statements describe the transaction as a strategic addition to Analog Devices' AI-oriented power delivery capabilities, addressing what Empower has characterized as a limiting factor for high-performance AI processors.

Empower's stated mission

Empower CEO Tim Phillips described the firm's founding purpose as targeting "the hardest problem in AI power delivery" - the power bottleneck that can constrain AI throughput. According to Phillips, Empower's technology is intended to provide the power density, speed and efficiency necessary for AI processors to operate at full capacity.

Timing and approvals

The companies said the acquisition is expected to close in the second half of 2026 and remains subject to regulatory approvals. That timeline establishes a multi-year horizon before the deal is finalized and before combined operations are fully integrated.

Leadership and advisory roles

Following completion of the transaction, Tim Phillips will continue to lead efforts on integrated voltage regulator technology at Analog Devices. Financial advisers on the deal include PJT Partners advising Analog Devices and Barclays advising Empower Semiconductor.

Market reaction

Shares of Analog Devices were reported to be up 1.2% after the bell following the announcement.


This transaction is positioned as a targeted expansion of Analog Devices' power management capabilities for AI and heavy compute applications, with an emphasis on resolving limits created by power delivery constraints.

Given the stated timeline and the need for regulatory clearances, the full impact of the acquisition will depend on the completion of approvals and the subsequent integration of Empower's technology into Analog Devices' product roadmap.

Risks

  • Regulatory approval is required for the transaction to close, introducing uncertainty about timing and completion - this affects the semiconductor and AI infrastructure sectors.
  • The expected close in the second half of 2026 delays when combined technologies and capabilities would be available to customers and markets - impacting AI compute and power management adoption timelines.
  • Power delivery constraints remain a core challenge for AI throughput; the extent to which the acquired technology mitigates that bottleneck is a stated objective but will depend on execution.
