Micron posts record $41.5B revenue as AI memory demand surges

Micron Technology reported fiscal third-quarter revenue of $41.46 billion, up 346 percent from a year earlier, as high-bandwidth memory demand from AI data centers drove the largest quarterly sales figure in the company's history.

"Micron's record fiscal Q3 financial results and even stronger outlook for Q4 reflect the strategic value of memory in the AI era," Chief Executive Officer Sanjay Mehrotra said.

Non-GAAP earnings per share reached $25.11, up from $1.91 in the year-ago period, as net income climbed to $28.2 billion. The company guided fiscal Q4 revenue to approximately $50 billion and non-GAAP EPS approaching $31 per share, both of which would represent records by wide margins. According to Goldman Sachs, Micron accounted for roughly 51 percent of all S&P 500 earnings-per-share revisions during the measured period.

The stock has fallen more than 20 percent from its recent high amid a broader semiconductor pullback, even as the company's underlying business accelerated. Micron's shares have still gained more than 600 percent over the past 12 months, making it one of the best performers in the iShares Semiconductor ETF, where it now represents 7.73 percent of assets.

Memory cycle durability is the key question for investors

The central debate around Micron centers on whether high-bandwidth memory pricing and margins can persist as competitors expand production. Supply eventually responds to high prices, and customers can adjust spending, but for now, demand continues to outpace available capacity. The company's Q4 guidance implies sequential revenue growth of roughly 21 percent, suggesting management sees no near-term easing in AI-driven demand.

Guidance raise signals confidence in AI demand trajectory

The Q4 outlook of $50 billion in revenue and $31 in non-GAAP EPS represents a significant acceleration from already elevated levels. Micron's earnings revisions have been the single largest contributor to S&P 500 estimate changes, according to Goldman Sachs, reflecting how aggressively expectations have been repriced around memory demand. The guidance raise signals management expects AI infrastructure spending to sustain its current pace through at least the end of the fiscal year.

The company's position in high-bandwidth memory, a critical component for AI inference workloads, has given it pricing power in what was historically one of the most commoditized segments of the semiconductor industry. Rival SK Hynix controls 56 percent of the HBM market, according to the company, while Micron's share is estimated at 21 percent. SK Hynix began trading on the Nasdaq on July 10 after raising about $26.5 billion in the largest U.S. IPO ever by a foreign company.

For holders, the guidance raise provides a strong directional signal that AI memory demand remains intact despite the broader chip sector selloff. Investors will watch for any signs of supply normalization or pricing pressure in the quarters ahead, with the next key catalyst being the company's Q4 earnings report expected in late September.
