Micron Technology reported fiscal fourth-quarter revenue of $54.23 billion, up 379.3% from a year earlier, as demand for memory used in artificial-intelligence infrastructure lifted revenue, profitability and earnings to records. GAAP operating profit reached $43.75 billion, with an 80.7% operating margin, while non-GAAP net income was $38.40 billion, or $33.42 per diluted share. Revenue exceeded the $51.07 billion LSEG consensus estimate, and adjusted earnings surpassed the $31.61 estimate. Micron forecast first-quarter fiscal 2027 revenue of $61.5 billion, plus or minus $1.5 billion, and non-GAAP earnings of $38.15 per share, both above market expectations. The company is mass-producing 36GB 12-layer HBM4 for NVIDIA's next-generation AI platforms, while expanding HBM output has tightened general DRAM supply and supported broader memory pricing.
