Micron Technology to report fiscal Q4 earnings amid market downturn

Micron Technology is preparing to deliver its fiscal fourth-quarter 2026 earnings on September 30, and the timing could hardly be more dramatic. The company’s shares have slid from a post-Q3 peak above $1,200 to around $933 in late August, a roughly 22% haircut courtesy of a broader equity market selloff.

The results will land during what has historically been the market’s roughest stretch, but Micron’s underlying business tells a different story than the stock chart. The company is guiding for approximately $50 billion in quarterly revenue and non-GAAP earnings per share of about $31, numbers that would represent yet another step-change in a fiscal year already defined by explosive growth.

A Q3 that rewrote the playbook

To understand why the upcoming report matters, rewind to Micron’s fiscal Q3. Revenue came in at $41.46 billion, a jaw-dropping 346% year-over-year increase that blew past consensus estimates in the $35-36 billion range.

Non-GAAP EPS hit $25.11, also comfortably above expectations. The driver behind those numbers was demand for DRAM and high-bandwidth memory, the specialized chips that power AI training and inference workloads, which has turned Micron from a cyclical commodity supplier into something closer to an AI infrastructure play. The company’s gross margins reflect that transformation. Q4 guidance puts gross margin at approximately 86%.

For context, Micron posted a $5.8 billion loss in its fiscal 2023, when the memory pricing cycle swung violently downward.

What the guidance signals

Micron’s Q4 guidance of $50 billion in revenue (plus or minus $1 billion) would represent a meaningful sequential acceleration from the $41.46 billion posted in Q3. Capital expenditure is expected to land around $10 billion for the quarter, a signal that management sees enough demand runway to justify pouring money back into capacity expansion.

That level of investment is notable because Micron has simultaneously acknowledged persistent supply constraints that it expects will extend into 2027 and beyond. CEO Sanjay Mehrotra has highlighted strategic agreements with customers that include price floors and sustainable supply commitments, positioning Micron advantageously against the volatility historically seen in the memory sector.

The stock versus the story

The disconnect between Micron’s operational momentum and its recent share price performance is the central tension heading into the report. Shares trading around $933 represent a steep discount from the $1,200-plus levels reached after Q3 results landed.

Historical analysis of Micron’s post-earnings stock performance shows mixed results, often driven more by the prevailing macroeconomic mood than by the numbers themselves.

Investors will want to hear how Micron characterizes demand trends heading into fiscal 2027, particularly around AI-related memory products. If Micron’s Q4 results align with or exceed its $50 billion revenue target and $31 EPS guidance, it could signal the health of the AI-related memory sector and potentially lead to stock price stabilization or growth, reversing the recent downward trend.
