AI Infrastructure Demand Drives Growth for Semiconductor and Assembly Firms

The expansion of artificial intelligence infrastructure is driving significant stock and revenue growth for several key semiconductor and hardware firms. Micron Technology reported blowout fiscal 2026 third-quarter earnings, projecting over 20% sequential growth for the fourth quarter. While Micron's second-quarter revenue grew 196% year-over-year, Sandisk outpaced this growth with a 251% year-over-year increase in its fiscal 2026 third quarter.

This surge is fueled by high demand for memory components, specifically Micron's DRAM and high-bandwidth memory and Sandisk's NAND flash memory. Supporting this long-term trend, Nvidia expects global data center capital expenditures to reach between $3 trillion and $4 trillion annually by 2030.

Parallel to memory growth, specialized infrastructure and assembly providers are scaling operations. Benchmark Electronics saw its Advanced Computing & Communications segment revenue rise 41% year-over-year to $105 million in Q1 2026, leading the company to raise its full-year revenue growth guidance to 9-10%. Meanwhile, Amkor Technology is addressing AI chip packaging bottlenecks by developing a new advanced packaging and test campus in Arizona, intended to capture volume from AI silicon providers such as Broadcom Inc.
