Analogue Devices to Acquire Empower Semiconductor for AI Data Centres
The AI chip market has landed another major deal. Analogue Devices has agreed to acquire Empower Semiconductor in a $1.5 billion all-cash transaction. PJT Partners is advising Analogue Devices, while Barclays is advising Empower. The companies expect the deal to close in the second half of 2026.
Empower Semiconductor operates in the fast-growing AI chip ecosystem, and this acquisition comes at a time when investment in data centre infrastructure is surging. As generative AI workloads expand, data centres need denser, faster, and more power-hungry hardware. Because of that, power management has moved from a background function to a critical competitive advantage.
Empower specialises in power management semiconductors, the chips responsible for regulating and delivering power inside servers and data centres. In other words, it focuses on the layer that keeps AI infrastructure running efficiently. As energy demand rises across GPU clusters, this capability becomes increasingly valuable. That is exactly the gap Empower is designed to fill.
For Analogue Devices, this acquisition strengthens its position in the AI infrastructure supply chain. More importantly, it adds a capability that fits directly into its existing portfolio across industrial, automotive, and communications chips. Instead of building this expertise from scratch, Analogue Devices is buying speed and technical depth.
The timing also supports the move. Analogue Devices reports its second-quarter earnings on May 20, and analysts expect record revenue of about $3.5 billion, based on Bloomberg-compiled data. That strong performance gives the company more confidence to proceed with a deal of this size.
Interestingly, sources had suggested the transaction could be announced as early as Tuesday. The company confirmed the deal on May 19, matching that timeline.
The Bigger Picture in Chip M&A
This is not an isolated transaction. Semiconductor consolidation is accelerating as companies race to control larger parts of the AI infrastructure stack. At the same time, power management chips are gaining new importance. AI clusters consume massive energy, and even small efficiency gains can translate into major savings at scale.
That is why Empower’s technology matters. By acquiring the company, Analogue Devices secures a stronger role in the infrastructure conversation, not just in chip performance but in power efficiency. Ultimately, the $1.5 billion price tag reflects both the strategic value of Empower’s work and the urgency driving AI-driven data centre investment. Analogue Devices is buying positioning, not just product.
