Micron Technology, Inc. (MU) reported a significant 196% increase in revenues year-over-year, totaling $23.86 billion for the second quarter of fiscal 2026. Additionally, non-GAAP earnings per share (EPS) surged 682% to $12.20, exceeding Zacks Consensus Estimates by 21.67% for revenue and 38.57% for EPS. The company’s strong performance is attributed to its focus on memory solutions for AI and data centers, alongside a diversification strategy away from volatile consumer electronics.

Marvell Technology, Inc. (MRVL) also reported growth, with a 22% year-over-year increase in revenues to $2.22 billion in the fourth quarter of fiscal 2026. Custom silicon revenues reached $1.5 billion, supported by rising demand from hyperscalers and high-performance computing clients. The company forecasts over 50% growth in its interconnect business for fiscal 2027, driven by increased reliance on high-speed connectivity for AI workloads.

In terms of growth outlook, Micron’s fiscal 2026 estimates predict a 194.5% revenue growth and a 604% EPS increase, significantly outpacing Marvell’s projected 32.3% revenue growth and 34.2% EPS increase in fiscal 2027. While Micron trades at a forward P/E ratio of 5.42, Marvell’s stands at 36.39, suggesting investors may pay a premium for MRVL despite its lower growth profile. Micron has also outperformed with a 516.2% stock price increase over the past year compared to Marvell’s 181.4% gain.
