Analog Devices in talks to buy Empower Semiconductor for $US1.5b

Analog Devices (Nasdaq: ADI) is in advanced talks to buy Empower Semiconductor for about US$1.5 billion in cash, Reuters reported. The deal would add a specialist in on-chip voltage regulation to one of the largest analogue chipmakers at a moment when power delivery has become a bottleneck in AI data centres.

Empower Semiconductor makes integrated voltage regulators and power-management chips for AI, high-performance computing and other dense workloads. Its silicon sits between the board-level power supply and the processor, converting and regulating voltage directly on the chip package.

For Analog Devices — whose own catalogue spans analogue, mixed-signal and power products across data centres, communications gear and industrial systems — the acquisition would deepen its reach into a layer of the semiconductor stack that only grows more important as processors pull more current.

The talks are advanced, according to the Reuters report, but neither company had announced a transaction as of 19 May. At US$1.5 billion, the price is large enough to register yet small enough for ADI to absorb comfortably against a market capitalisation of US$204.35 billion, according to Yahoo Finance. The question for investors is whether controlling more of the power stack helps ADI win a larger slice of AI server spending.

ADI shares last traded at US$418.58. A US$1.5 billion acquisition would equal less than 1 per cent of its market value. It is a bolt-on, not a balance-sheet event.

Analog Devices approaches the reported talks with improving momentum behind it. Revenue in the fiscal first quarter of 2026 rose 30 per cent year on year to US$3.16 billion. Chief executive Vincent Roche said the quarter built on existing momentum. Chief financial officer Richard Puccio attributed bookings growth to broad industrial demand and record orders from the data-centre segment. ADI would not be buying from weakness; it would be layering new capability onto markets that are already recovering.

The AI hardware build-out has squeezed not just the processors doing the computation but the supporting components that supply them with clean, efficient power. Empower has aimed itself at that exact constraint. On its company site, it describes its products as power delivery for AI and high-performance computing — a niche that sits squarely inside the spending surge around accelerated servers and networking equipment.

Empower has been scaling its own capital base too. A Series D round raised more than US$140 million, and founder Tim Phillips said the syndicate backing the company showed the strength of its technology, market opportunity and customer adoption. That level of private funding does not prove a sale was inevitable, but it signalled a company arriving at a juncture where further private expansion or an exit to a larger chip group both looked plausible. Buying rather than partnering would give Analog Devices tighter control over a technology layer its customers increasingly care about.

The reported talks slot into a familiar semiconductor-sector pattern. Large analogue and mixed-signal chipmakers have used acquisitions for years to plug product gaps, deepen customer ties and reach higher-margin end markets. What distinguishes this one is the target’s narrowness. It is not a broad microcontroller or sensor deal. It is a wager that power efficiency and power density for AI and data-centre infrastructure will stay scarce enough to make specialist IP worth paying for. For chip companies chasing data-centre budgets, that layer now sits closer to the buying decision than it did a cycle ago.

The Australian read-across is indirect but not abstract. Local enterprise buyers and data-centre operators do not source chips from takeover headlines, but the vendors serving them are being reshaped by the same race to support AI infrastructure with lower losses, tighter thermal envelopes and more reliable power conversion. A completed Empower deal would hand Analog Devices another lever with hyperscale and industrial customers. Even if the talks fall apart, they broadcast the same message: power delivery, once a background detail of board design, is becoming one of the more valuable pieces of the semiconductor stack.
