Micron Earnings Preview: Five Key Things Memory Investors Need to Watch
AI Podcast
Micron Technology will report its fourth-quarter fiscal 2026 financial results after market close on September 30, Eastern Time. Driven by robust AI server demand and rising memory prices, the company projects revenue between $49 billion and $51 billion, Non-GAAP EPS of $30 to $32, and an 86% gross margin. Key investor focuses include fiscal Q1 2027 guidance, sustainability of tight DRAM supply, HBM4 customer validation and order conversion, enterprise SSD expansion in data centers, and 2027 capital expenditure and capacity plans. These metrics will critically influence Micron's earnings outlook and broader memory industry trends.
TradingKey - Micron Technology (MU) will report its fourth-quarter fiscal 2026 financial results after the market close on September 30, Eastern Time, and host an earnings conference call at 16:30 on the same day.
Growing demand for AI servers, rising memory prices, and an improved product mix drove up Micron's revenue and gross margin in the third fiscal quarter, with operating cash flow also increasing significantly.
The company expects fourth-quarter fiscal revenue to be $49 billion to $51 billion, Non-GAAP earnings per share to be $30 to $32, and gross margin to be approximately 86%. Market focus will be on the first-quarter fiscal 2027 guidance and whether tight memory supply can persist.
Here are five key points for investors to watch regarding Micron's earnings report:
Will Fourth-Quarter Results and Next-Quarter Guidance Beat Expectations?
Micron's third-quarter results showed significant improvement, while market expectations for the fourth quarter fall in the upper-middle range of company guidance.
Metric | Q3 FY2026 | Q4 FY2026 Guidance | Recent Market Expectations |
Revenue | $41.456 billion | $49 billion–$51 billion | Approximately $50.4 billion |
Non-GAAP EPS | $25.11 | $30–$32 | Approximately $30.90 |
Non-GAAP Gross Margin | 84.90% | Approximately 86% | Close to 86% |
Net Capital Expenditures | $7.1 billion | Not Disclosed | — |
Adjusted Free Cash Flow | $18.3 billion | Not Disclosed | — |
In the third fiscal quarter, combined revenue from the cloud storage and core data center businesses reached $25.293 billion, accounting for approximately 61% of total revenue. If fourth-quarter revenue reaches only the guidance midpoint of $50 billion, it will fall short of recent market expectations.
Post-earnings stock performance will depend more heavily on the Q1 FY2027 guidance. The outlook for revenue, gross margin, and DRAM average selling price will reflect whether AI server demand and memory prices can continue driving earnings growth.
Can DRAM Prices and High Gross Margins Be Sustained?
AI servers continue to boost demand for HBM, high-capacity DDR5, and server DRAM, with major manufacturers also allocating more wafer and packaging resources to high-end products. As major expansion projects remain under construction or in the capacity ramp-up phase, server memory supply stays tight.
Micron's third-fiscal-quarter Non-GAAP gross margin rose to 84.9% from 74.9% in the previous quarter, and the company expects it to further reach approximately 86% in the fourth fiscal quarter. The market will closely focus on whether the gross margin can remain at a high level in the next quarter.
Demand for mobile phone and PC memory is weaker than that of the AI server market. TrendForce expects that AI and server products will continue to see demand support, but a slowdown in consumer electronics procurement may limit price increases for certain consumer DRAM and NAND products. The revenue share of server products will affect Micron's future profit margins.
Can HBM4 Customer Verification Translate Into Orders?
While Micron, SK Hynix (SKHY), and Samsung continue to supply HBM3E, their competitive focus is shifting toward HBM4 and HBM4E.
Company | HBM4 Progress | HBM4E Progress | Key Points to Watch |
Micron | High-volume shipments to major customer platforms have begun, with qualification samples provided to multiple end customers | Utilizes 1γ process, with mass production planned for 2027 | New customer qualification, HBM4 capacity, and 2027 shipment schedules |
SK Hynix | Volume shipments to begin in Q2 2026, with plans to expand output in the second half of the year | Sample deliveries completed | M15X capacity ramp-up and customer procurement scale |
Samsung | Commercial shipments achieved, with continued capacity expansion | Samples provided to major customers | Customer qualification, product yield, and output expansion |
Whether Micron can convert more qualification customers into volume purchasing customers will impact its HBM revenue growth rate and customer structure in 2027. On the earnings call, key points to watch include customer qualification progress, capacity arrangements, and management's latest outlook on 2027 shipments.
Can Enterprise SSDs Expand Data Center Revenue?
AI storage demand is expanding from model training to inference, real-time retrieval, vector databases, and KV caching. TrendForce stated that North American cloud service providers recently raised their enterprise SSD demand forecasts, with fourth-quarter orders potentially exceeding those of the third quarter, supporting demand for both TLC and QLC products.
Micron has begun shipping its 245TB QLC SSD, and its high-performance PCIe 6.0 SSDs featuring G9 NAND have also entered mass production. Growing enterprise SSD demand helps increase the share of data center products in Micron's NAND business.
Investors can monitor enterprise SSD shipments, NAND average selling prices, and product mix. If growth in server products fails to offset slowing demand for mobile and consumer storage, NAND prices and profit margins may remain under pressure.
How Will Capital Expenditures and New Capacity Be Planned for 2027?
Micron's net capital expenditures for the third fiscal quarter were $7.1 billion, with adjusted free cash flow reaching $18.3 billion. The company is increasing investments in advanced processes, fabs, and packaging capacity, while enhancing demand, supply, and pricing visibility through long-term customer agreements.
Competitors are also expanding capacity. SK Hynix is accelerating mass production at M15X and plans to open its Yongin Phase 1 cleanroom in early 2027; Samsung continues to expand HBM4 capacity and prioritizes the supply of server products such as HBM4 and DDR5.
The capital expenditures, equipment installation, and timing of new capacity ramp-ups across the three manufacturers will shape memory supply and demand in 2027. If demand growth continues to outpace supply, DRAM and HBM prices will remain supported; if the release of new capacity accelerates, memory prices and manufacturers' gross margins may face downward pressure.
The focus of this earnings report extends beyond whether fourth-fiscal-quarter revenue can hit $50 billion to include guidance for the first quarter of fiscal 2027, HBM4 customer qualification, DRAM pricing, and capital expenditure plans. These metrics will impact Micron's earnings outlook and provide a reference point for gauging the trajectory of SK Hynix, Samsung, and the memory industry as a whole.
