Micron (MU) Earnings Date: When Q4 FY2026 Reports and What to Watch

Micron Technology (MU) has not yet announced the date of its Q4 FY2026 earnings report as of August 26, 2026. Micron's recent cadence puts its prints on Wednesdays (FY2026: Q1 on December 17, Q2 on March 18, Q3 on June 24), and last year's Q4 report landed on September 23, 2025. On that pattern, late September 2026 (around September 22–23 US time) is the working expectation. Some calendar sites list September 29; none of these are company announcements. This article will be updated the same day Micron confirms the date.

Company guidance: the benchmark for the print

Micron's own guidance for fiscal Q4 2026, issued with its Q3 results on June 24, 2026, is the baseline the reported figures should be read against. This article does not carry analyst consensus or price targets.

• Revenue: US$50.0 billion ± $1.0 billion (GAAP and non-GAAP)
• Gross margin: approximately 86% (GAAP and non-GAAP)
• Operating expenses: about $1.86 billion GAAP / $1.65 billion non-GAAP
• Diluted EPS: $30.73 ± $1.00 GAAP / $31.00 ± $1.00 non-GAAP

The comparison base: fiscal Q3 2026 (ended May 28, 2026) revenue was $41.46 billion (versus $23.86 billion in Q2 and $9.30 billion a year earlier), with GAAP net income of $28.24 billion ($24.67 per diluted share), non-GAAP net income of $28.86 billion ($25.11), and operating cash flow of $25.39 billion. All figures are from Micron's own press release filed with the SEC.

What to watch

• Actuals versus the company's own plan — where revenue lands inside the $50.0B ± $1.0B band and whether gross margin holds near 86%.
• A 14-week quarter — Micron's fiscal year ends on the Thursday closest to August 31 (September 3, 2026 this year), and FY2026 is a 53-week year, so Q4 contains an extra week versus a normal quarter. Sequential comparisons carry that extra week.
• HBM progress — as of the Q3 report, Micron said HBM4 built on its 1-beta DRAM technology was in high-volume shipment for its lead customer's platform.
