The News: Micron Technology, Inc. (NASDAQ: MU) reported Q4 FY 2025 revenue of $11.32 billion (consensus: $11.15 billion), up 46% year-on-year (YoY) from $7.75 billion. Non-GAAP gross margin expanded to 45.7% (consensus: 44.3%), versus 36.5% in Q4 FY 2024. Non-GAAP net income rose to $3.47 billion, compared with $1.34 billion in the year-ago period.
Micron Q4 FY 2025 Earnings Top Estimates on DRAM and HBM Strength
Analyst Take: Micron’s Q4 FY 2025 results capped a record-breaking year, with revenue, gross margin, and EPS all coming in above expectations. The company’s performance was powered by DRAM strength, HBM ramp, and broader AI-driven demand across data center, PC, and mobile segments. With more than half of its revenue now tied to data centers, Micron has firmly positioned itself as a central beneficiary of AI infrastructure spending. The setup for FY 2026 is supported by tight supply/demand, favorable pricing trends, and an aggressive technology roadmap spanning 1-gamma DRAM, HBM4, and G9 NAND.
That said, while management commentary was broadly positive, investors should keep a close memory cycle—especially in NAND and DRAM—given how quickly momentum can shift. On HBM, Micron struck a confident tone around HBM4’s technical capabilities and production timeline, but the recent specification changes and ongoing ASP risks remain watch points.
Data Center and HBM Momentum
Micron’s data center business accounted for 56% of its company revenue in FY 2025, with HBM alone reaching nearly $2 billion in Q4 FY 2025. HBM demand has been driven by AI server growth, and Micron’s share is expected to align with its broader DRAM share in the coming quarters. The company shipped HBM4 samples with bandwidth above 2.8 TB/s and pin speeds exceeding 11 Gbps, claiming industry leadership in performance and efficiency. Its six-customer HBM base, with most FY 2026 supply already under pricing agreements, underscores visibility and pricing discipline. Tight DRAM supply across the industry enhances profitability for HBM and mainstream DRAM, strengthening Micron’s competitive position.
DRAM Pricing Power and Technology Roadmap
Micron’s data center business accounted for 56% of revenue in FY 2025, with HBM alone reaching nearly $2B in Q4. Demand has been driven by hyperscaler AI server growth, and Micron’s HBM share is expected to converge with its broader DRAM share over time.
Micron shipped HBM4 samples with pin speeds exceeding 11Gb/s and bandwidth above 2.8TB/s, claiming leadership on performance and efficiency. Management also announced HBM4E collaboration with TSMC, including customized logic die options—an important step for deepening customer stickiness and raising gross margins. Its six-customer HBM base provides near-term visibility, though the company acknowledged that the FY26 supply is not yet fully sold out. While this may raise concerns, we view the more material risk as pricing pressure in HBM3E and HBM4 as Samsung ramps and NVIDIA continues pushing for lower HBM costs.
The DDR4 supply environment has tightened as memory makers shift capacity to DDR5 and HBM, with even CXMT pivoting toward DDR5. DDR5 supply is also constrained as hyperscalers prioritize HBM capacity. These dynamics underpin Micron’s pricing strength into 2026.
The rollout of 1-gamma DRAM—achieving mature yields 50% faster than prior nodes—provides both cost and performance leverage. Micron is also the sole LPDRAM supplier in NVIDIA’s GB family, strengthening its foothold in AI servers. With inventories lean across suppliers and customers, and server demand expected to grow ~10% YoY in 2025, the company is structurally positioned for a favorable DRAM cycle extending into 2026.
NAND and Client Market Recovery
NAND revenue came in at $2.2B (-5% YoY, +4.5% QoQ), supported by high-single-digit ASP gains and improving industry conditions. The stronger backdrop is underpinned by:
- Hyperscaler demand for eSSDs in data centers.
- Structural HDD shortages are tightening the overall storage market.
- AI inference workloads drive exponential KV cache offload into persistent SSD/HDD storage.
- The ongoing token explosion from models like OpenAI’s Sora and Google’s Veo3, which will only accelerate as image/video inference scales.
Micron’s G9 NAND and PCIe Gen6 SSD launches underscore its ability to lead in next-gen performance storage. Visibility for eSSD orders now stretches through 2026, and rising SSD ASPs should provide sustained tailwinds.
In PCs, Windows 10 end-of-life and AI PC adoption are boosting shipments (mid-single-digit growth expected in 2025). DRAM content continues to rise in mobile, with one-third of flagship smartphones shipping with 12GB+ of DRAM. Together, these factors give NAND demand breadth beyond the data center.
Automotive and Embedded Strength
The automotive and Embedded segment posted 27% sequential growth in Q4, with margins benefiting from pricing and a richer mix. Demand is being driven by ADAS systems and AI-enabled in-cabin experiences, which require higher DRAM and NAND content. Embedded markets—robotics, drones, AR/VR—are also emerging as longer-term growth drivers, supported by Micron’s LP5 and D5 adoption.
Guidance and Final Thoughts
Micron guided Q1 FY 2026 revenue of $12.2B–$12.8B (consensus: $11.9B), with non-GAAP gross margin expected at 50.5%–52.5% (consensus: 45.7%). The ~600 bps sequential margin expansion underscores a constructive backdrop—tight DRAM supply, improving NAND pricing, and lean customer inventories all working in Micron’s favor.
On capex, Micron raised its FY26 budget to $18B, up ~30% YoY from $13.8B in FY25. The bulk of this spend is earmarked for:
- 1-gamma DRAM ramps, where Micron aims to accelerate yield maturity and secure cost/performance leadership.
- HBM assembly and test capacity support the company’s transition from HBM3E to HBM4/HBM4E and deepen integration with TSMC’s logic die roadmap.
- New fab construction under the U.S. CHIPS program, positioning Micron to expand domestic capacity while benefiting from government incentives.
This step-up in investment highlights Micron’s long-term confidence in memory demand growth—not just from AI data centers but also from structural shifts in PCs, mobile, and automotive.
