Analog Devices (ADI) had a pretty good quarter. Actually, a really good quarter. The chipmaker reported fiscal second-quarter 2026 results that beat Wall Street expectations on both revenue and earnings, and also announced a $1.5 billion acquisition of Empower Semiconductor to further its push into AI infrastructure. But the stock fell nearly 6% on Wednesday, because markets are markets.
Let's start with the numbers. ADI reported Q2 revenue of $3.62 billion, up 37% from a year ago and above the analyst consensus of $3.51 billion. Adjusted earnings came in at $3.09 per share, topping the $2.90 estimate. That's a clean beat, and the kind of quarter that usually sends a stock higher. But ADI shares were down 5.97% at $390.26 at the time of publication, according to market data. The likely explanation: investors were taking profits after a strong run, because the earnings beat was already priced in.
The real story here is the AI boom. ADI's communications revenue — which includes data center — jumped 79% to $554.73 million, and the company said data center now accounts for more than 75% of that segment, growing over 90% year over year. That's being driven by demand for optical and power products that are essential for AI data centers. Industrial revenue, ADI's largest segment, rose 56% to $1.8 billion, representing 50% of total revenue. Automotive revenue grew 2% to $871.57 million, and consumer revenue was up 23% to $397.76 million.
Margins are expanding nicely, too. Adjusted gross margin expanded 360 basis points to 73%, and adjusted operating margin jumped 780 basis points to 49%. That's impressive operating leverage. Cash flow remains strong: ADI generated $872 million in operating cash flow during the quarter and $734 million in free cash flow. Over the trailing 12 months, free cash flow was $4.6 billion. The company returned $1.3 billion to shareholders through dividends and buybacks in the quarter. As of May 2, it held $2.44 billion in cash and equivalents.
CEO Vincent Roche said Q2 revenue, profitability, and EPS all exceeded the high end of the company's guidance, despite geopolitical and macroeconomic pressures. He noted that ADI is seeing record demand across its product portfolio, supported by its hybrid manufacturing model and supply-chain flexibility. The company identified AI-driven computing and connectivity, autonomy, healthcare, energy transition, and immersive consumer technologies as major long-term growth drivers.
Management added that ADI's data center and automated test equipment businesses continue to benefit from strong AI infrastructure spending and are positioned for further growth heading into 2027. Industrial markets — including automation, healthcare, energy, and electronic test and measurement — grew more than 40% during the first half of fiscal 2026. Factory automation, robotics adoption, and reshoring trends are key demand drivers for ADI's sensing, connectivity, and power-management technologies.
Now, about that acquisition. ADI is buying Empower Semiconductor for $1.5 billion. Empower makes integrated voltage regulator and silicon capacitor technologies used in AI data centers and high-performance computing systems. The deal is expected to close in the second half of 2026, pending regulatory approvals. ADI said Empower's technologies could reduce power footprints, improve compute density, and lower energy consumption in AI data centers, while broadening ADI's exposure to AI accelerator infrastructure.
CFO Richard Puccio said industrial and communications growth was driven by demand for data center, optical, and power products. He added that automotive growth benefited from gains in advanced driver-assistance systems, infotainment platforms, and battery-management systems for electric vehicles.
Looking ahead, ADI issued a strong Q3 outlook. The company forecast revenue of $3.80 billion to $4.00 billion, above analyst estimates of $3.62 billion. It also projected adjusted earnings of $3.15 to $3.45 per share, ahead of the Street consensus of $3.00 per share. That's a solid guide, suggesting the momentum is continuing.
So why did the stock fall? Sometimes a good quarter isn't enough. The market may have been expecting even more, or investors simply decided to take some chips off the table. Either way, ADI's underlying business looks strong, and the AI infrastructure theme is clearly driving growth. The Empower acquisition should only add to that story.
