Shares of Analog Devices (ADI) fell sharply on Wednesday despite the semiconductor company reporting stronger-than-expected fiscal second-quarter results and announcing a $1.5 billion acquisition aimed at expanding its artificial-intelligence power management business.
The stock dropped more than 4% during the session after rallying roughly 53% so far in 2026 amid growing investor optimism around AI-related semiconductor demand.
Analog Devices reported adjusted earnings of $3.09 per share for the quarter ended in April, well above Wall Street expectations of roughly $2.90 per share.
Revenue climbed 37% year over year to $3.62 billion, also topping analyst forecasts of approximately $3.51 billion.
The company pointed to strong momentum in its data-center business, where revenue surged more than 90% compared with a year earlier.
Analog Devices said demand was driven by both its optical and power chip portfolios, which are increasingly used in AI infrastructure.
Industrial and communications segments drive growth
The company’s industrial business, which accounted for about half of total quarterly revenue, rose 56% year over year.
Meanwhile, the communications segment, representing roughly 15% of sales, jumped 79%.
Analog Devices credited strong customer demand and operational execution for the stronger-than-expected performance.
“Our innovation-led value creation strategy targets our customers’ most complex and consequential challenges with a goal of delivering substantial and sustained business impact,” said CEO Vincent Roche.
Chief Financial Officer Richard Puccio said the company continued to see improving demand trends across several key end markets, including industrial, automotive, and communications.
The company also issued an upbeat outlook for its fiscal third quarter.
Analog Devices forecast revenue of $3.9 billion, plus or minus $100 million, ahead of analysts’ consensus estimate of roughly $3.6 billion.
It also projected adjusted earnings per share of approximately $3.30, plus or minus $0.15, compared with Wall Street expectations of around $3.01 per share.
Management said booking trends remained strong and indicated that positive demand conditions are expected to continue into the current quarter.
Empower acquisition targets AI power demand
The earnings report followed Analog Devices’ announcement late Tuesday that it would acquire privately held Empower Semiconductor in a $1.5 billion all-cash transaction.
Empower develops power delivery technologies used in AI computing systems, an increasingly important area as rising compute density in data centers drives demand for more efficient energy management solutions.
The companies said the acquisition would allow power conversion systems to move closer to processors, improving efficiency, power density, and system-level performance for AI workloads.
“[Analog Devices] already delivers some of the highest-performance power management solutions in the industry,” Roche said. “With Empower we are further expanding our portfolio to help customers rearchitect their power systems and achieve the compute densities next-generation AI demands.”
Semiconductor peers trade mixed
Despite the strong earnings report and optimistic guidance, investors appeared to take profits following the stock’s substantial rally this year.
Among other analog semiconductor companies, Texas Instruments rose slightly on Wednesday, while Microchip Technology gained 1.92% and ON Semiconductor advanced more than 3%.
Analog Devices’ results reinforced continued strength in AI-related semiconductor demand, particularly in data centers and industrial applications, even as the stock reacted negatively in the short term.
