How HBM Makes Micron Unstoppable

Micron (NASDAQ:MU) is undergoing a significant structural transformation driven by its High-Bandwidth Memory (HBM) segment, which saw nearly 50% sequential revenue growth and propelled gross margins into the high-30% range, with data center DRAM now comprising the majority of sales. This HBM-led shift, bolstered by co-design ties with hyperscalers and next-gen HBM4 sampling, secures multi-year supply contracts and stabilizes ASPs, yet the market appears to undervalue this durability, reflected in a forward P/E under 16x despite projected 50% EPS growth from FY25 to FY26.

Analysis

Micron is demonstrating a significant structural transformation, pivoting from cyclical memory dynamics to a more stable, high-margin business driven by its High-Bandwidth Memory (HBM) segment. This shift is evidenced by a near 50% sequential surge in HBM revenue, which has propelled data center DRAM to represent the majority of total DRAM sales and expanded gross margins into the high-30% range. Operationally, the company is executing with discipline, reducing inventory days-on-hand while simultaneously increasing bit shipments by double digits. Despite this fundamental improvement, valuation metrics suggest the market has not fully recognized this change. The stock trades at a forward P/E below 16x, which appears disconnected from strong earnings projections forecasting 50% EPS growth from approximately $7.80 in FY25 to $12 in FY26. Furthermore, strategic co-design partnerships with hyperscalers and the sampling of next-generation HBM4 are securing multi-year supply contracts, which should stabilize average selling prices (ASPs) and insulate the company from broader industry oversupply risks.

Key Decisions for Investors

• Given the disconnect between the forward P/E of under 16x and a projected 50% EPS growth, investors should evaluate whether the market is undervaluing Micron's structural shift to higher-margin HBM products.
• Consider the company's long-term revenue visibility, enhanced by multi-year supply contracts with hyperscalers, as a key factor that mitigates traditional cyclical risks associated with the DRAM market.
• Investors should monitor upcoming quarterly results for sustained gross margin performance in the high-30% range and continued momentum in data center sales to confirm the durability of this HBM-driven business transformation.
