Analog Devices is in advanced talks to acquire closely held Empower Semiconductor for roughly $1.5 billion in cash, with an announcement possible as soon as Tuesday, Bloomberg reported on May 19. The Milpitas, California company designs integrated voltage regulators that mount directly beneath GPUs and other AI accelerators and deliver more than 3,000 amps of current per package — a power-delivery layer that hyperscalers have spent the last 18 months trying to secure as accelerator current draw has run past what board-level VRMs can supply.
What ADI is actually buying
Empower's flagship is the Crescendo platform, unveiled in October 2024, which the company markets as vertical power delivery (VPD): the regulator sits underneath the silicon instead of out on the motherboard, shortening the path between switcher and load. Empower says the architecture enables over 10% reduction in power delivery losses versus traditional power delivery architectures at multi-thousand-amp current draws. In February 2026 the company added embedded silicon capacitors (ECAPs) targeted at next-generation AI processors — a complementary part of the same in-package power story.
The company was founded in 2014 and closed a Series D of more than $140 million in September 2025, led by Fidelity Management & Research. Bloomberg's report does not name customers, though Empower's published positioning is squarely at hyperscalers and GPU vendors' reference designs.
Strategic fit for a $200B chipmaker
For Analog Devices — market cap around $205 billion, with shares trading near 52-week highs heading into Wednesday's Q2 print — Empower slots into its power-management franchise and gives it a credible answer to the in-package power roadmap Monolithic Power Systems, Infineon, and Vicor are all chasing. ADI is paying for VPD intellectual property and a power-design team, not fab capacity. The bet is that the next two generations of AI accelerators are gated by how many amps can be pushed through how few millimeters of copper, and that the regulator vendor sitting directly under the die collects rent on every socket.
What it means for the AI infrastructure stack
Big Tech capex above $650 billion in 2026 across Microsoft, Alphabet, Amazon, Meta, and Apple has moved the bottleneck twice in twelve months — first from GPU allocation to data-center power, and now from rack-level power to in-package current delivery. A consolidation move on Empower locks one of the credible independent VPD vendors inside a $200B+ incumbent with the distribution and supply commitments hyperscalers prefer, and likely pulls forward similar M&A interest in the remaining specialists.
For builders shipping anything that runs on rented Blackwell, MI400, or TPU capacity, the immediate read is that the per-watt economics of inference are about to depend less on the accelerator vendor's roadmap and more on whose voltage regulator is bonded to it. Pricing power in 2027 sits with whoever owns that interposer-adjacent real estate.
