NAND flash memory inventory, primarily consisting of solid-state drives (SSD), has been declining since the second half of last year and is currently at a level comparable to DRAM. The company is fully committed to expanding HBM4 production, aiming to capture an "overwhelming" market share, and admitted that even with full capacity, it is still difficult to meet demand SK Hynix released a clear signal during its latest earnings call: the supply tightness in the memory market will continue, and the company is fully committed to expanding production of high-end products but still cannot fully meet customer demand. This supply-demand pattern is expected to persist in the second half of this year. SK Hynix stated that **the DRAM inventory in the fourth quarter has significantly decreased year-on-year, with products being shipped to customers immediately after production, leaving almost no room for inventory accumulation.** The company expects that as time progresses into the second half of this year, DRAM inventory will further shrink, and the supply tightness for customers may continue for some time. In terms of high bandwidth memory (HBM) business, SK Hynix revealed that **despite currently maximizing production of HBM4, it is still difficult to fully meet customer demand.** The company's goal is to gain an overwhelming market share in the HBM4 market, continuing its dominance in HBM3 and HBM3E products. Additionally, the company holds a cautious attitude towards large-scale manufacturing expansion in the United States but has announced an investment of $10 billion to establish an AI solutions company in the U.S., utilizing advanced chip technologies, including HBM, to provide optimized AI systems for data center customers. ## Continued Tight Supply of Memory SK Hynix elaborated on the current supply situation during the conference call. The company's DRAM inventory saw a significant year-on-year decline in the fourth quarter, with produced products being shipped immediately to customers, leaving little room for inventory accumulation. The company further pointed out that DRAM inventory is expected to further contract in the second half of this year, which means that the supply tightness for customers may continue for quite some time. **In terms of NAND flash memory, SK Hynix stated that inventory, primarily consisting of solid-state drives (SSD), has been declining since the second half of last year and is currently at a level comparable to DRAM.** ## HBM4 Strategy: Targeting Overwhelming Market Share SK Hynix's HBM4 supply strategy became the focus of the conference call. The company stated its goal is to gain an overwhelming market share in the HBM4 market, continuing its dominance achieved in HBM3 and HBM3E products. The company emphasized that its competitiveness in the HBM market is not limited to technological leadership; since the HBM2E era, it has helped shape the market through close collaboration with customers and infrastructure partners. SK Hynix stated that its accumulated mass production experience and the trust earned in product quality represent advantages that are difficult to replicate in the short term. To achieve the goal of obtaining an overwhelming market share, SK Hynix is focusing on improving yield rates to levels comparable to the previous 12-layer HBM3E, striving to occupy a leading position in the HBM4 market. ## Full Capacity Still Cannot Meet Demand Despite fully expanding production, SK Hynix admitted that supply remains tight. **The company stated that it is currently maximizing production but still finds it difficult to fully meet customer demand,** and expects some competitors to enter the market. However, SK Hynix emphasized that its market leadership and position as a leading supplier will continue. Regarding HBM4 technology, SK Hynix stated that the fifth-generation (1b) process at the 10nm level used in existing products has met customer performance requirements. The company added that its goal is to capture demand by leveraging its proprietary packaging technology **SK Hynix has shown a cautious attitude towards overseas expansion.** Regarding the anticipated U.S. semiconductor tariffs, the company stated that it is currently monitoring discussions between the South Korean and U.S. governments. The company mentioned that investments in overseas semiconductor fabs involve numerous internal and external variables that must be carefully assessed, and it will share future directions at a later stage. It is noteworthy that despite its cautious stance on large-scale manufacturing expansion in the U.S., SK Hynix has developed a selective investment plan. The company announced that it will establish an AI solutions company in the U.S., tentatively named AI Company (AI Co.), utilizing advanced chip technologies, including HBM, to provide optimized AI systems for data center customers. SK Hynix stated that it will invest $10 billion in this enterprise, deploying it through capital calls ### Related Stocks - [159516.CN - Guotai CSI Semiconductor Material Equipment Theme ETF](https://longbridge.com/en/quote/159516.CN.md) - [512480.CN - GTJA Allianz CSI All Share Semiconductors & Semiconductor Equipment ETF](https://longbridge.com/en/quote/512480.CN.md) - [512760.CN - Guotai CES Semiconductor Chip Industry ETF](https://longbridge.com/en/quote/512760.CN.md) - [588780.CN - GTJA Allianz SSE STAR Chip Design Thematic ETF](https://longbridge.com/en/quote/588780.CN.md) - [07709.HK - XL2CSOPHYNIX](https://longbridge.com/en/quote/07709.HK.md) - [588170.CN - ChinaAMC SSE STAR Semiconductor Material & Equipment Thematic ETF](https://longbridge.com/en/quote/588170.CN.md) ## Related News & Research | Title | Description | URL | |-------|-------------|-----| | 三星、海力士 “调整战略”：新存储工厂生产计划提前 | SK 海力士计划将其龙仁一期晶圆厂的试运行时间提前至明年 2-3 月，三星电子将平泽 P4 工厂的投产时间从明年一季度提前至今年四季度，生产规划前移约三个月。调整源于 AI 数据中心扩张导致供应严重短缺，主要客户需求满足率仅 60%。市场普 | [Link](https://longbridge.com/en/news/276302716.md) | | 存储巨头四季报 “五大关键点”：当前周期强度超越 2017-18“云繁荣周期” | 美银美林指出，SK 海力士库存周转天数降至 127 天的低位，成品库存仅剩 2-3 周。三星 DRAM 售价环比大涨 40%，现货价格创 25 年新高。行业高管认为，本轮周期强度已超越 2017-18 年的云繁荣期，若短缺持续至 2027 | [Link](https://longbridge.com/en/news/276035827.md) | | “这很难，但我相信你们”！黄仁勋上周宴请 SK 海力士工程师，亲自敬酒，敦促 “无延迟交付 HBM4” | 英伟达 CEO 黄仁勋罕见 “亲自出马”，在硅谷韩式餐厅宴请 30 多名工程师，敦促 SK 海力士按时交付第六代 HBM4。随着三星率先出货搅动战局，这场关乎下一代 AI 芯片 Vera Rubin 成败的供应链争夺战已进入白热化，SK 海 | [Link](https://longbridge.com/en/news/276298764.md) | | 美光 CFO 对 HBM 有信心，存储股全线走高 | 美光 CFO 表示，公司已开始 HBM4 芯片的量产和出货。这一表态了缓解了市场对其在 HBM4 领域落后竞争对手的担忧。大摩大幅上调美光目标价，并表示 SK 海力士虽将在第一季度向英伟达供应 HBM4，但美光从第二季度开始也能实现供货，时 | [Link](https://longbridge.com/en/news/275688469.md) | | 铠侠翻身仗：打破定价枷锁，NAND 价格 1 季度有望暴涨 50% | Daishin Securities 估计，从 2026 年第一季度开始，针对北美客户的修订定价政策将生效，ASP 预计环比提升约 50%。这标志着铠侠摆脱历史遗留约束的关键时刻，也是移动 NAND 价格正常化的拐点。摩根士丹利更为激进地预 | [Link](https://longbridge.com/en/news/275842502.md) | --- > **Disclaimer**: This article is for reference only and does not constitute any investment advice.
