Micron Q3 Earnings Preview: Gross Margin 81%, Surpassing Nvidia! Will the AI Memory Super Cycle Trigger a 14% Stock Price Volatility?

Benefiting from the AI boom driving explosive demand for memory chips, Micron Technology (MU.O) will announce its fiscal third-quarter results after the US stock market closes today (24th). Market consensus expects Micron’s Q3 revenue to increase nearly 280% year-over-year, surpassing $34.5 billion, with gross margin reaching a record high of 81%. However, after Micron’s market capitalization officially broke the $1 trillion mark, options markets estimate that stock price volatility after the earnings report could reach as high as 14%. Investors are closely watching its HBM4 progress and subsequent guidance.

• Revenue nearly tripled, gross margin expected to reach a record high of 81%
• HBM4 capacity sold out, Q4 guidance becomes the biggest market variable
• Options warning: 14% intense volatility, has the AI cycle peaked?

US memory chip giant Micron Technology is set to release its fiscal third-quarter (Q3 FY2026) earnings report after the US stock market closes on Wednesday (24th) Taipei time. Over the past year, driven by the huge demand for high-bandwidth memory (HBM) in AI infrastructure, Micron’s stock price has skyrocketed more than 7 times, with market value successfully surpassing $1 trillion, rivaling Korean giants Samsung and SK Hynix.

Revenue nearly tripled, gross margin expected to reach a record high of 81%

This AI-driven memory supercycle has led to explosive growth in Micron’s performance. According to market consensus, Micron’s Q3 revenue is estimated to be between $34.5 billion and $35.6 billion (a year-over-year increase of 270% to 283%), far exceeding the company’s previous guidance of a median of $33.5 billion. Additionally, non-GAAP EPS is expected to reach $19.6 to $20.8, nearly 10 times higher than the same period last year.

What’s most shocking to the market is its incredible profitability. Due to severe supply shortages pushing up memory chip prices, Micron’s gross margin in Q2 reached 74.4%, and market expectations for Q3 gross margin are further climbing to a record high of 81% to 81.6%, surpassing even NVIDIA, the AI chip leader. Besides HBM contributions, the DRAM, which accounts for about 77% of total revenue, and strong NAND business are key drivers of gross margin expansion.

HBM4 capacity sold out, Q4 guidance becomes the biggest market variable

In the upcoming earnings call, Wall Street analysts will focus on Micron’s HBM progress and capacity allocation. Currently, Micron’s HBM4, developed for next-generation platforms like NVIDIA’s Vera Rubin, has begun mass production, and the entire supply for 2026 has been confirmed sold out. Investors are eager to learn about the actual revenue contribution from HBM4, the status of supply contracts for 2027, and whether prices for non-HBM DRAM can continue to stay strong.

However, the market’s high expectations also bring significant concerns. Due to the company’s rapid growth, the guidance for the fourth quarter (Q4) will be more important than the already achieved Q3 figures. Currently, analysts estimate Micron’s Q4 revenue at $42.5 billion and EPS at $24.80. If Micron provides guidance similar to Q2, significantly exceeding expectations, the stock could hit new highs; but if any key indicator (such as gross margin growth) underperforms, the current near-trillion-dollar valuation could trigger a “sell the news” sell-off.

Options warning: 14% intense volatility, has the AI cycle peaked?

In fact, high valuation and high volatility have become recent market themes for Micron. Just before the earnings release on Tuesday, Micron’s stock price plunged 13% in a single day, mainly due to concerns that leverage ETFs linked to Samsung and SK Hynix might intensify selling pressure in related sectors. According to current options pricing data, traders expect stock price swings of about 14% after the earnings announcement, corresponding to a dramatic reshuffling of over $150 billion in market value.

Micron management previously expressed optimism that data center and AI-related memory supply shortages would persist beyond 2026, with some key customers only able to meet 50% to two-thirds of their demand. Although AI chip demand currently shows no signs of slowing, and new capacity takes years to build, structurally this is a positive for Micron; however, the memory industry is highly cyclical in the long term. Analysts warn that stock prices often lead profit peaks. For investors who have already gained over 7 times their investment, taking profits at the historic high of a $1 trillion market cap might be the most realistic reflection of market psychology amid this 14% turbulence.
