Micron Guidance Fuels Memory-Stock Rally
Micron guidance on Oct. 19, 2026 lifted memory shares as banks forecast stronger DRAM and NAND pricing through 2027, heightening focus on supply risk.
KEY TAKEAWAYS
- Micron guided fiscal Q1 revenue to $60-$63 billion and GAAP gross margin to 86.0%.
- J.P. Morgan raised Q4 DRAM growth to 10%-15% and NAND to 15%-20%.
- Micron's Idaho output and CXMT's projected 77% wafer capacity growth could pressure memory pricing.

Micron guidance sent memory-chip stocks higher in U.S. premarket trading on Oct. 19, 2026, after the company projected fiscal‑Q1 revenue and an elevated gross‑margin outlook. Broker forecasts for stronger DRAM and NAND prices through 2027 reinforced the move.
Micron Results and Outlook
Micron Technology (MU) reported record quarterly revenue of $54.2 billion for the quarter ended Sept. 3, 2026. The company guided fiscal Q1 2027 revenue to $60 billion–$63 billion and forecast GAAP gross margins of 86.0%.
This outlook followed a sharp selloff the prior week, attributed to concerns about AI data-center financing, capital spending durability, and competition from Chinese memory manufacturers. Executives said more than 75% of fiscal 2027 shipments were already committed, with most revenue governed by pricing frameworks that include floors and ceilings.
Management also said they lacked clear visibility on when memory supply and demand would balance. Micron’s Idaho facility is expected to begin wafer production in mid-calendar 2027, potentially adding supply after a period of tight conditions.
Pricing and Capacity Outlook
Broker forecasts for higher DRAM and NAND pricing through 2027 supported investor sentiment. J.P. Morgan raised its Q4 2026 DRAM contract-price growth forecast to 10%–15% and its NAND forecast to 15%–20%.
Market data showed SK hynix (SKHY) increased third-quarter selling prices about 22% for DRAM and 15% for NAND. Counterpoint Research estimated SK hynix held roughly 50% of global high-bandwidth-memory (HBM) revenue in Q2 2026, compared with 33% for Samsung Electronics and 18% for Micron. Analysts projected HBM4 average selling prices could rise about 121% year-over-year through next year, with prices near $3–$5 per gigabyte, supporting demand for premium memory products.
A market forecast projected China’s ChangXin Memory Technologies (CXMT) wafer capacity could expand from about 290,000 wafers at the end of 2026 to roughly 513,000 at the end of 2028, a 77% increase. This growth could create a supply overhang if demand softens.
Bank of America expected strong selling prices, revenue, and margins from late 2026 through 2028 but projected limited sequential growth in 2027 and a single-digit annual EPS decline in 2028. The bank cited replacement demand for AI-related data-center memory such as LPDDR5, SOCAMM, HBM, and enterprise solid-state drives, and noted AI workloads would support server DDR5 orders through 2027.
Investors will watch SanDisk (SNDK) when it reports on Oct. 29, 2026, for additional insight on NAND pricing, margins, and guidance. Recent memory-stock moves reflected operating results, pricing forecasts, and investor positioning rather than merger or regulatory developments.
