Micron reported fiscal Q4 2026 revenue of $54.23 billion, up 379% year-over-year from $11.32 billion, driven by record AI-driven demand across cloud and data-center segments. GAAP net income reached $37.70 billion, or $32.87 per diluted share, compared to $3.20 billion ($2.83 per share) in Q4 2025. Full-year 2026 revenue totaled $133.19 billion versus $37.38 billion in FY2025. Gross margin expanded to 86.8% GAAP (87.0% adjusted) in Q4 from 44.7% year-ago. Operating margin reached 80.7% GAAP (82.3% adjusted). All four business units—Cloud Memory, Core Data Center, Mobile and Client, and Automotive and Embedded—posted double-digit gross margins, with Core Data Center achieving 90% gross margin. Management launched multiple advanced memory products, including 512GB DDR5 modules and industry-leading server LPDDR offerings. For Q1 2027, Micron guided revenue of $61.5 billion ± $1.5 billion with ~86% adjusted gross margin and $38.15 adjusted EPS, signaling continued AI-driven momentum and "even stronger" fiscal 2027 performance.

Micron's stock rises even as Chinese rival CXMT increases pressure on commodity DRAM pricing.
Micron's stacked high-bandwidth memory for AI accelerators, the core of its AI growth story. Its 12-high HBM3E (36GB) is among the industry's most power-efficient, with ~30% lower power than rivals, and ships into Nvidia's Hopper/Blackwell platforms. Micron is now in high-volume production of HBM4 36GB 12-high, hitting 11+ Gb/s pin speeds and 2.8+ TB/s bandwidth, designed into Nvidia's Vera Rubin generation. Micron's entire 2026 HBM output is sold out under signed agreements.
Micron's mainstream DRAM in module form for servers, PCs, and AI systems: high-capacity DDR5 RDIMMs/MRDIMMs for data centers, low-power LPDDR5X for mobile and AI inference, and SOCAMM, a compact, swappable low-power module co-developed for Nvidia's AI servers. These products carry Micron's leading-edge 1-beta and 1-gamma DRAM process nodes into the broad memory market alongside its HBM franchise.
Micron's graphics DRAM for GPUs and accelerators, shipping on Nvidia's Blackwell RTX 50-series cards. GDDR7 pushes pin speeds toward and beyond 40 Gbps, delivering the bandwidth needed for high-end gaming, workstation, and AI-inference GPUs. It is a key piece of Micron's portfolio for accelerated computing outside the HBM stack.
Micron's flagship enterprise NAND storage. The PCIe Gen5 9550 NVMe targets AI training and data-center workloads with high throughput and power efficiency, while the newer 9650 is among the first PCIe Gen6 data-center SSDs, reaching up to 28 GB/s sequential reads and 5.5M random-read IOPS in liquid-cooled environments. These drives anchor Micron's storage business built on its vertically integrated 3D NAND.
