Micron Beats Earnings Estimates Amid Surge in AI Chip Demand

Micron Technology announced on Wednesday that it surpassed its fourth-quarter earnings estimates, as robust demand for artificial intelligence (AI) infrastructure continues to bolster the company's business. Revenue for the fourth quarter reached $54.23 billion, exceeding the $51.07 billion expected by LSEG consensus estimates. This marks a nearly fourfold increase from the $11.32 billion reported in the same quarter last year. The company's stock saw a slight increase in extended trading following the announcement. A key driver for Micron's performance is the soaring demand for high-bandwidth memory (HBM), a critical component for AI. Micron is the sole U.S.-based manufacturer of HBM, which consists of stacked DRAM chips. Fourth-quarter DRAM revenue surged 343% year-over-year to $39.8 billion, representing 73% of total sales. Looking ahead, Micron projects first-quarter revenue of approximately $61.5 billion and adjusted earnings per share of $38.15. This outlook surpasses analyst expectations of $57 billion in revenue and $35.40 per share. The company's stock has experienced a remarkable rally, increasing by over 500% in the past year, driven by the AI chip shortage. To meet this escalating demand, Micron is undertaking significant investments to expand its production capacity, including the construction of two new HBM manufacturing campuses in New York and Idaho. Competitors, such as SK Hynix and Samsung, are also increasing their HBM production in South Korea. Micron CEO Sanjay Mehrotra recently participated in a White House summit focused on AI regulation.
