Analog Devices (ADI) has announced a definitive agreement to acquire Empower Semiconductor for $1.5 billion in cash, marking one of the largest acquisitions in the chipmaker's recent history. The deal, unveiled on Monday, underscores ADI's strategic push into power management solutions tailored for the insatiable energy demands of artificial intelligence data centers.
Empower Semiconductor, based in Milpitas, California, specializes in integrated voltage regulators (IVRs) that sit directly beneath AI accelerators like GPUs and TPUs. Unlike traditional power delivery architectures that route current laterally across the circuit board, Empower's technology feeds current vertically through the substrate, significantly reducing parasitic losses. According to the company, this design can cut total system power consumption by roughly 20%—a critical gain when a single hyperscale data center can draw hundreds of megawatts.
"AI infrastructure is fundamentally reshaping how power must be delivered, with energy now the most persistent constraint to scaling next-generation systems," said Vincent Roche, chief executive and chair of Analog Devices. "Empower's differentiated integrated voltage regulator technology will expand our portfolio and help customers achieve the compute densities that next-generation AI demands."
The acquisition comes at a time when AI workloads are exploding in complexity and scale. Training large language models like GPT-4 or running inference on thousands of accelerators requires enormous electrical power, and data center operators are increasingly focused on efficiency as a competitive differentiator. Startups and established players alike are racing to develop new power architectures that can deliver cleaner, more stable voltage to processors while minimizing waste heat. Empower's solution is one of the few that has demonstrated tangible, measurable improvements in field deployments.
Founded in 2014, Empower has been on a rapid growth trajectory. In September 2025, the company closed a Series D funding round of more than $140 million led by Fidelity Management & Research, with participation from Maverick Silicon, CapitalG (Alphabet's growth fund), Atreides Management, and others. That round brought total funding to approximately $236 million across multiple rounds. Empower also opened a new corporate headquarters in Milpitas and a dedicated research and development center in Munich, Germany, signaling ambitions to serve a global customer base.
Analog Devices, headquartered in Wilmington, Massachusetts, designs and manufactures chips for industrial, automotive, communications, and consumer-electronics markets. It is the third-largest U.S.-listed chipmaker not primarily focused on processors, with a market capitalization now exceeding $200 billion. The company's shares have gained more than 52% this year, driven by strong demand in the AI data center supply chain. ADI is expected to report second-quarter earnings on Tuesday, with analysts forecasting record revenue of roughly $3.5 billion.
The Empower deal marks ADI's largest acquisition in years, reflecting its determination to capture more value in the fast-growing power management segment. The combined portfolio will integrate Empower's FinFast technology and Crescendo power platform into ADI's existing "grid-to-core" power delivery chain, which spans everything from AC/DC converters to point-of-load regulators. The goal is to offer customers a complete, optimized solution that can handle the most demanding AI workloads.
The broader AI infrastructure market is awash with capital. Nvidia alone has committed more than $40 billion in AI equity investments so far in 2026, while Meta recently signed a $27 billion data center deal with cloud infrastructure company Nebius. Energy costs have become a central bottleneck, with operators scrambling to secure enough power and cooling capacity to bring new facilities online. Startups like Empower that can reduce power consumption or improve thermal management are attracting premium valuations.
Tim Phillips, co-founder and chief executive of Empower, will remain with ADI to lead the development of integrated voltage regulators within the larger company. The transaction is expected to close in the second half of 2026, subject to regulatory clearance under the Hart-Scott-Rodino Act. PJT Partners advised Analog Devices on the transaction, while Barclays acted for Empower.
With this acquisition, Analog Devices is betting that the chips closest to the processor—those that manage voltage and power delivery—will play an increasingly vital role in enabling the next wave of AI innovation. As energy costs continue to escalate, the ability to deliver power efficiently and reliably at the point of load is becoming a defining competitive advantage for data center operators and chipmakers alike.
