Micron to Report Q4 Earnings: Buy, Hold, or Take Profits Now?

Micron Technology (MU) is anticipated to report robust fiscal Q4 2025 results on Sept. 23, with management forecasting $10.7 billion in sales (up 38% YoY) and $2.50 EPS (up 112% YoY), attributing growth to low inventory and strong demand. This positive outlook is significantly underpinned by escalating AI infrastructure capital expenditure from major tech firms, driving critical demand for Micron's high-bandwidth memory (HBM) solutions, which are supplied to key players like NVIDIA for its Blackwell chips and also to AMD, positioning Micron favorably across the competitive AI chip market.

Analysis

Micron Technology is positioned for significant growth ahead of its fiscal fourth-quarter 2025 earnings report, underpinned by strong management guidance and powerful secular tailwinds in the artificial intelligence sector. The company projects Q4 revenue of $10.7 billion, representing a 38% year-over-year increase, and an earnings per share (EPS) of $2.50, a 112% rise. This forecast builds upon a robust third quarter that saw a 37% YoY revenue jump to $9.3 billion and a 208% EPS surge to $1.91, driven by a nearly 50% sequential increase in high-bandwidth memory (HBM) sales. Management attributes the optimistic outlook to low inventory levels and high demand, which are expected to enable favorable pricing and an improved product mix, consequently boosting operating margins. The core driver of this demand is a surge in AI infrastructure capital expenditures from tech leaders including Alphabet, Meta, and Amazon. Micron holds a critical and strategically advantageous position within this ecosystem, supplying its HBM3E memory not only to NVIDIA for its market-leading Blackwell GPUs but also to its primary competitor, AMD, for the MI350 series. This dual-supplier role mitigates customer concentration risk and ensures Micron's growth is tied to the broader expansion of the AI accelerator market, with future prospects reinforced by the planned launch of its HBM4 solution next year.

Key Decisions for Investors

• Given the strong management guidance for 38% YoY revenue growth and a 112% YoY EPS increase, investors should evaluate the potential for Micron to meet or exceed these targets, as confirmation would validate the bullish thesis driven by the AI demand cycle.
• Monitor management's commentary on the HBM market, specifically its supply agreements with both NVIDIA and AMD, as Micron's ability to serve both of these key AI chipmakers is a significant competitive advantage that de-risks its growth outlook.
• Investors should look beyond the headline Q4 numbers for any updates on the HBM4 product roadmap and the company's forward-looking perspective on AI-related capital expenditure trends, as these are critical indicators for sustained momentum into 2026.
