Analog Devices to Acquire Empower Semiconductor, Expanding its Next-Generation High-Density Power Portfolio for the AI Era
- Addresses a critical challenge in AI – delivering high-density, energy-efficient compute as power and thermal demands limit system scale
- Further advances ADI's position as a leading strategic, system-level grid-to-core power partner for hyperscalers and AI silicon developers
- Expands ADI's total addressable market in AI compute power delivery with Integrated Voltage Regulator (IVR) and Silicon Capacitor technology solutions
WILMINGTON, Mass. and MILPITAS, Calif., May 19, 2026 /PRNewswire/ -- Analog Devices, Inc. (NASDAQ:ADI) and Empower Semiconductor today announced that they have entered into a definitive agreement under which ADI will acquire Empower in an all-cash transaction for $1.5 billion.
As AI compute scales, power density – not just total watts – has become the limiting factor. Delivering high-density, high-efficiency power at the point of compute, while responding to fast-changing demands, is now one of the most critical challenges in system design.
Together, ADI and Empower will help shape the power delivery architecture for AI and other compute-intensive applications. By enabling power conversion closer to the processor, the combined solution shortens the power delivery path and improves efficiency to support higher-performance, higher-density systems. Building on its leadership in high-performance power management, ADI is investing in its system-level platform to deliver a step-change in performance, density, and efficiency from grid to core.
Commentary
- "AI infrastructure is fundamentally reshaping how power must be delivered, with energy now the most persistent constraint to scaling next-generation systems. ADI already delivers some of the highest-performance power management solutions in the industry, and with Empower we are further expanding our portfolio to help customers rearchitect their power systems and achieve the compute densities next-generation AI demands. The impact of this technology extends well beyond AI data centers to any domain where energy constrains what is possible," said Vincent Roche, CEO and Chair at ADI.
- "Empower was founded to solve the hardest problem in AI power delivery – the power bottleneck that is limiting AI throughput. Our technology enables the power density, speed and efficiency required by AI processors to reach their full potential, unleashing generations of performance improvements. The combination of ADI's power management platform, scale and operational excellence, along with the system level benefits our merger enables, will accelerate our adoption with customers," said Tim Phillips, CEO of Empower Semiconductor.
Empower's silicon capacitors are already in production, and IVR programs are advancing in close collaboration with leading hyperscalers and AI silicon providers – capabilities ADI will accelerate through its scale, manufacturing, and customer reach.
Transaction Details
Under the terms of the agreement, which has been approved by the Boards of Directors of both companies, ADI will pay Empower's stockholders $1.5 billion in an all-cash purchase price. The transaction is expected to close in the second half of calendar year 2026, subject to customary closing conditions and the expiration of the applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. Following the closing of the Transaction, Mr. Phillips will continue leading IVR technology efforts as part of ADI.
