Micron Q3 2025 slides: Record revenue driven by AI demand, strong FQ4 outlook

Micron Technology (MU) reported record fiscal Q3 2025 results, with revenue reaching $9.3 billion and diluted EPS of $1.91, significantly driven by robust demand for AI memory, particularly high-bandwidth memory (HBM) and data center products. The company provided strong Q4 2025 guidance, projecting $10.7 billion in revenue and $2.50 EPS, and announced plans for $200 billion in US investments over 20 years to expand manufacturing and R&D. While Micron subsequently exceeded its Q4 guidance with actual revenue of $11.32 billion and EPS of $3.03, the stock experienced a slight after-hours decline, potentially reflecting investor concerns over increased capital expenditures planned for 2026, despite the company's strong positioning to capitalize on AI-driven memory growth.

Analysis

Micron Technology (MU) reported record fiscal Q3 2025 revenue of $9.3 billion, a 37% year-over-year increase, significantly driven by robust demand in the artificial intelligence (AI) memory market, particularly high-bandwidth memory (HBM) and data center products. Diluted EPS reached $1.91, supported by a 39.0% non-GAAP gross margin, showcasing strong operational execution.

DRAM revenue, comprising 76% of total, surged 51% year-over-year, with the Compute and Networking Business Unit experiencing a nearly 50% sequential increase in HBM revenue. Micron's strategic $200 billion investment plan in the US, including new fabs and R&D, aims to bolster its leadership in advanced memory technologies like the 1-gamma DRAM node.

Micron subsequently exceeded its strong fiscal Q4 2025 guidance, achieving $11.32 billion in revenue and $3.03 EPS, with gross margin surpassing 50% for the first time since 2018. Despite this significant outperformance, MU's stock declined 1.77% after-hours, potentially reflecting investor concerns over increased capital expenditures planned for 2026. The company's market outlook projects favorable supply-demand dynamics for both DRAM and NAND, with bit supply growth expected below industry bit demand.

Key Decisions for Investors

• Monitor Micron's execution on its $200 billion strategic investment plan and the associated capital expenditure ramp-up for 2026, as this appears to be a key driver of recent market reaction.
• Evaluate the sustainability of Micron's HBM and data center segment growth, given its strong market positioning and the projected favorable supply-demand balance in DRAM and NAND.
• Consider the long-term implications of Micron's technological advancements, such as the 1-gamma DRAM node, for its competitive advantage and future profitability in the evolving AI memory landscape.
