Micron Technology reported a significant surge in earnings growth for its second quarter of fiscal year 2026, surpassing Nvidia’s contribution to the S&P 500’s overall profit expansion. The Idaho-based memory manufacturer’s profit growth in Q2 2026 was reported to be over 1,200% year-over-year, positioning it as a leading driver of the index’s earnings.
Further demonstrating its robust performance, Micron Technology announced fiscal third quarter 2026 results that included $41.46 billion in revenue, a substantial increase of 346% compared to the same quarter in the previous year. The company also posted a net income of $28.24 billion and achieved a gross margin of 84.9% for the quarter. Micron is forecasting approximately $50 billion in revenue and an 86% gross margin for its fiscal fourth quarter of 2026.
Analysts project that Micron’s operating income could climb from an estimated $130.4 billion in 2026 to $200.8 billion in 2027, representing a projected increase of 54%. Together, Micron and Nvidia accounted for up to 40% of the S&P 500 index’s earnings growth in the most recent quarter, underscoring the significant impact of these semiconductor giants on the broader market.
Despite this impressive financial performance and growth trajectory, Micron’s stock is trading at a forward price-to-earnings ratio of approximately 9.2x. This valuation is notably lower than the S&P 500’s weighted average forward P/E of around 20.2x and the information technology sector’s average of 22.8x. This suggests that Micron is trading at less than half the multiple of its own sector, even as it demonstrates faster growth than many of its peers.
Micron’s growth is reportedly running ahead of the broader memory market, indicating that the company is capturing a disproportionate share of the highest-margin artificial intelligence memory products. Industry-wide DRAM growth rates are guided in the low-to-mid 20s percent for calendar 2026, while NAND growth rates are guided at roughly 20%. Supply constraints in High Bandwidth Memory (HBM) are expected to persist beyond 2027, potentially supporting continued demand for Micron’s specialized products.
Micron has also secured long-term supply agreements with key customers, including Nvidia itself, which provides a degree of revenue visibility. However, uncertainties remain regarding the precise extent of the combined contribution of Micron and Nvidia to S&P 500 earnings growth and the exact resolution timeline for HBM supply constraints beyond 2027.
The company’s performance highlights its strategic position in the AI-driven semiconductor market, while its current valuation presents a point of interest for investors and market observers evaluating its future potential.
