Micron is due to report fiscal third-quarter results after the U.S. market close on July 24, with investors focused on two headline figures: revenue of $34.5 billion to $35.6 billion and gross margin of 81% to 81.6%. If those estimates hold, Micron would post another sharp step up in profitability as AI-driven memory demand keeps reshaping expectations for the sector. In the options market, traders are already pricing in a post-earnings move of about 14%.
The stock has surged more than sevenfold over the past year, helped by strong demand for high-bandwidth memory used in AI infrastructure. That rally pushed Micron’s market value above $1 trillion and turned the company into one of the most closely watched names in the AI memory trade. The setup is simple. Expectations are now extremely high.
Revenue growth and margins are the main numbers to watch
Consensus estimates put Micron’s fiscal Q3 revenue growth at 270% to 283% year over year, above the company’s prior midpoint guidance of $33.5 billion. Non-GAAP earnings per share are expected to come in between $19.6 and $20.8, roughly ten times the level from a year earlier.
Margins may draw even more attention than revenue. Micron posted a 74.4% gross margin in fiscal Q2, and analysts now expect another jump this quarter as tight supply supports pricing power. The report also points to strength in both DRAM and NAND, with DRAM projected to contribute about 77% of total revenue. That mix remains central to the earnings story.
HBM4 output and 2027 supply deals are key questions
On the earnings call, Wall Street is likely to press management on HBM4 production and customer allocation. Micron has started mass production of HBM4 for next-generation platforms including Nvidia Vera Rubin, and the company’s entire 2026 HBM4 supply has already been sold out. Investors now want more than confirmation of shipments. They want to know how much that product is adding to revenue.
Attention is also shifting to 2027. The market is looking for signals on future supply agreements and whether pricing in non-HBM DRAM can stay firm. If Micron can show that strength extends beyond HBM, the case for sustained high margins becomes easier to support.
Q4 guidance may matter more than the reported quarter
For a stock that has already climbed so sharply, reported numbers alone may not settle the debate. Analysts currently expect fiscal Q4 revenue of about $42.5 billion and earnings per share of roughly $24.80. Those figures have become the next benchmark.
If management issues guidance similar to the upside surprise seen after fiscal Q2, the stock could keep pushing higher. If gross margin momentum slows or demand commentary comes in below market expectations, the reaction could turn quickly. That risk was visible before the report: Micron shares fell 13% in a single session on Tuesday.
Why the options market is bracing for a sharp reaction
Based on current options pricing, the implied post-earnings move of 14% points to a swing of more than $150 billion in market value. That is a sign of how split the market has become. On one side, Micron said last quarter that tight supply for data center and AI memory could persist beyond 2026, and that it could meet only 50% to two-thirds of demand from some key customers. On the other, memory remains a deeply cyclical business.
The debate now is less about whether AI demand is real and more about how much of that strength is already reflected in the stock. HBM4 execution, Q4 guidance, and pricing trends in non-HBM DRAM are likely to shape the next move.
