Micron's DRAM Revenues Hit $28.6B: Can the Momentum Continue?

Micron Technology (MU) reported record fiscal 2025 DRAM revenues of $28.6 billion, a 62% year-over-year increase, significantly driven by nearly $2 billion in Q4 High-Bandwidth Memory (HBM) sales, establishing an $8 billion annualized run rate from this AI-driven segment. Gross margins expanded to 41% in FY2025, with Q1 FY2026 revenue guided to $12.5 billion and gross margins projected above 51%, reflecting robust demand across data centers, AI PCs, and automotives amid tight industry supply conditions expected to drive continued price and margin expansion. This strong performance and positive outlook have contributed to an 86.1% year-to-date stock rally and upward revisions in fiscal 2026 earnings estimates.

Analysis

Micron Technology (MU) has reported exceptional fiscal 2025 results, primarily driven by its Dynamic Random Access Memory (DRAM) business. The company posted $28.6 billion in DRAM revenues, a significant 62% year-over-year increase, with fourth-quarter DRAM sales of $9 billion accounting for approximately 80% of total quarterly revenue. A critical growth catalyst is the high-bandwidth memory (HBM) segment, which is integral to AI servers; HBM sales reached nearly $2 billion in Q4, establishing an impressive $8 billion annualized run rate. This performance reflects strong, broad-based demand from data centers, PCs, and automotive sectors, compounded by favorable pricing from tight industry supply. The financial impact is evident in the substantial gross margin expansion to 41% in fiscal 2025, a notable increase from 24% in the prior year. The outlook remains robust, with Q1 fiscal 2026 revenue guided to approximately $12.5 billion, surpassing the consensus estimate of $12.14 billion, and gross margins are projected to exceed 51%. This forward-looking strength is underpinned by expectations of continued high-teens percentage growth in industry DRAM demand against Micron's disciplined supply growth, suggesting sustained pricing power and margin expansion. Despite an 86.1% year-to-date share price rally, the stock trades at a forward price-to-sales ratio of 3.43, slightly below its industry's average of 3.86, while fiscal 2026 earnings estimates have been revised upwards.

Key Decisions for Investors

• Given the strong earnings beat, upwardly revised guidance that exceeds consensus, and powerful tailwinds from the AI-driven HBM market, investors could view the current momentum as a strong signal to maintain or add to long positions.
• Investors should closely monitor gross margin performance, with the company's Q1 guidance of over 51% serving as a key benchmark for sustained profitability and pricing power in the tight DRAM supply environment.
• Despite the significant 86.1% year-to-date rally, the forward P/S valuation remains slightly below the industry average, suggesting that the stock may not be overvalued relative to its growth prospects and could have further room for appreciation if execution continues.
