01—Abstract
Summary
Summary of the 8-K filed May 19, 2026. Cited figures are marked; the original filing is the authoritative source.
Analog Devices (ADI) has entered into a definitive agreement to acquire Empower Semiconductor, a provider of integrated voltage regulators (IVRs) and silicon capacitor power management technology, in an all-cash transaction valued at $1.5 billiona.
The deal was announced on May 19, 2026 via an 8-K filed under Item 7.01 (Regulation FD Disclosure) with the joint press release furnished as Exhibit 99.1. The filing itself is a disclosure rather than a financial statement filing, so it contains no pro forma financials, purchase price allocation, or Empower revenue and earnings data. Strategically, the acquisition targets a bottleneck in AI infrastructure: power density at the point of compute.
ADI positions the combination as a grid-to-core power partner for hyperscalers and AI silicon developers, and says it expands ADI's addressable market in AI compute power delivery. Empower's silicon capacitors are described as already in production, with IVR programs in advanced collaboration with leading hyperscalers and AI silicon providers. Empower CEO Tim Phillips will continue leading IVR technology efforts within ADI after closing.
The transaction is expected to close in the second half of calendar 2026, subject to customary conditions and expiration or termination of the HSR waiting period. Key risks include regulatory review, integration of the acquired business, retention of key personnel, and whether the expected benefits materialize on schedule. Investors should look to future disclosures for Empower's financial profile, the funding source for the $1.5 billionb cash payment, and the expected accretion or dilution impact.

03—Questions
Frequently Asked Questions
How large is the acquisition and how will it be paid for?
The purchase price is $1.5 billion, paid entirely in cash to Empower's stockholders. The filing does not state how ADI will fund the payment, such as cash on hand or new debt, which investors should watch for in subsequent filings.
What does Empower Semiconductor do?
Empower develops integrated voltage regulators and silicon capacitor technology, using its FinFast technology to deliver high-density, efficient power directly at the processor. The company says its products reduce energy footprint and total cost of ownership in data centers.
When is the deal expected to close and what could delay it?
Closing is expected in the second half of calendar 2026. It is subject to customary closing conditions and the expiration or termination of the Hart-Scott-Rodino waiting period, including any extension. Regulatory approval risk and integration risk are the main factors that could delay or prevent closing.
Why is ADI making this acquisition?
ADI says power density has become a limiting factor in AI compute, and that moving power conversion closer to the processor improves efficiency and system density. The acquisition adds IVR and silicon capacitor technology to ADI's power portfolio and expands its addressable market in AI data center power delivery.
Will the deal affect ADI's financial results?
The filing provides no financial projections, revenue or earnings data for Empower, or accretion/dilution estimates. Investors should await disclosures in ADI's earnings releases or subsequent SEC filings for details on the financial impact.
