Revenue and Profitability Outlook - Revenue for FY2025 is projected at US$36,766 million, with a growth rate of 46%, while FY2026 revenue is expected to reach US$49,992 million, reflecting a growth rate of 36% [10][19]. - The report indicates that the market's expectations for Micron's revenue and net profit in FY2026-27 are too high, with projected net profits lower than market consensus by 10.1-48.2% [10][12][20]. Market Comparison and Price Trends - The report compares Micron's revenue forecasts with market predictions, noting a slight positive deviation for FY2025 but a negative deviation for FY2026 [5][18]. - The report highlights significant price increases in DRAM products, particularly due to supply constraints and production cuts by major manufacturers [7][11]. Valuation Methodology - The report employs a sum-of-the-parts (SOTP) valuation approach, assigning a P/E multiple of 10x for the DRAM segment and 5x for the NAND segment, leading to a total valuation of US$116.83 billion [19][21].

Core Viewpoint - The DDR4 memory market is experiencing a significant price surge due to major manufacturers exiting the DDR4 market, leading to a buying frenzy among OEM/ODM companies to secure DDR4 supplies. The current prices have exceeded those of DDR5, marking a notable shift in the market dynamics [1][2]. Price Surge - DDR4 spot prices have seen a dramatic increase, with daily price hikes nearing 8%, a level not observed in the past decade. The latest prices for DDR4 8Gb and 16Gb modules have surged significantly, with 8Gb modules reaching an average price of $3.775 and 16Gb modules at $8.2 [2][3]. Historical Price Comparison - Since June, the price of DDR4 8Gb modules has risen from an average of $2.73 to $3.775, marking a 38.27% increase in just half a month. Over the current quarter, prices have increased by approximately 132% from $1.63 [3][4]. Profitability Outlook - Current DDR4 prices are approaching levels seen in the first quarter of 2022, where companies like Nanya Technology and Winbond reported substantial profits, with gross margins of 43.9% and 48.6%, respectively [5][6]. Supply Constraints - Major manufacturers are gradually ceasing DDR4 production, leading to limited supply. This has resulted in a rush to purchase DDR4, particularly for industrial control applications where redesigning is challenging. Nanya Technology and Winbond are positioned to benefit from this price surge, with Nanya's DDR3 and DDR4 products accounting for over 80% of its revenue [7][8]. Future Prospects - Nanya Technology's DDR4 products have received positive feedback from several module manufacturers, and there is an expectation of increased shipments, which could help reduce inventory and potentially turn losses into profits by the fourth quarter [8][9].
