Strong Momentum in DRAM and NAND to Propel MU's Q4 Earnings

Micron Technology has significantly raised its fourth-quarter fiscal 2025 guidance, now forecasting revenues of $11.2 billion (+/-$100 million), non-GAAP gross margins of 44.5% (+/- 0.5%), and non-GAAP EPS of $2.85 (+/- $0.07). This substantial upward revision is driven by soaring demand for high-performance DRAM and NAND solutions, primarily fueled by the AI revolution and improved memory market pricing dynamics. The company's strategic role as a key supplier of HBM3E for NVIDIA's next-generation AI chips and strong momentum in data center SSDs underscore its enhanced market position amid the accelerating AI-driven memory and storage requirements.

Analysis

Micron Technology (MU) has issued a significant upward revision to its fourth-quarter fiscal 2025 guidance, signaling strong operational momentum and favorable market conditions. The company now anticipates revenues of $11.2 billion (+/- $100 million), a non-GAAP gross margin of 44.5% (+/- 0.5%), and non-GAAP EPS of $2.85 (+/- $0.07). This represents a substantial increase from prior guidance of $10.7 billion in revenue, 42.0% gross margin, and $2.50 in EPS. The primary catalyst for this improved outlook is the surging demand for high-performance memory driven by the artificial intelligence sector. Micron's DRAM segment is benefiting from both increased volume for AI applications and improved pricing dynamics, as the broader memory market stabilizes after prior oversupply issues. Critically, Micron is now in mass production of its HBM3E memory for NVIDIA's next-generation H200 AI GPUs, cementing its position as a key supplier in the AI hardware ecosystem. The company's NAND business is also showing strength, particularly from data center SSDs, where Micron achieved the #2 supplier position in the previous quarter, and from new design wins in the mobile sector.

Key Decisions for Investors

• Given the significant upward revision in revenue, gross margin, and EPS guidance, investors should reassess their financial models to reflect Micron's accelerated earnings power ahead of the Sept. 23 report.
• The strategic supplier relationship with NVIDIA for HBM3E memory is a core pillar of the bullish thesis; monitor the upcoming earnings call for commentary on production ramp, future demand signals from NVIDIA, and competitive positioning in the high-bandwidth memory market.
• Beyond the AI narrative, the noted stabilization and improved pricing in the broader DRAM and NAND markets are critical for margin expansion, making the durability of this pricing power a key factor to watch.
• Micron's ascendance to the #2 position in data center NAND SSDs indicates strong execution and market share gains, suggesting investors should track its competitive standing in both memory segments as a key performance indicator.
