金吾财讯 | 中国银河证券发研报指,AI需求驱动的存储芯片市场回暖,美光业绩大超市场预期。美光近期公布了FY26Q1财报,业绩和指引均超市场预期,从业绩来看,单季度实现收入136亿美元,yoy:+57%,qoq:+21%,毛利率57%,qoq:+11pct;净利润55亿美元,yoy:+169%,qoq:+58%,净利率40%。分产品来看,DRAM营收108亿美元,占比79%,yoy:+69%,qoq:+20%,出货量环比略有上升,ASP环比增长约20%;NAND营收27亿美元,占比20%,yoy:+22%,qoq:+22%,出货量环比增长中高个位数,ASP环比增长约15%。其中AI服务器增长是公司的核心业绩驱动,云存储业务收入55亿美元,yoy:+100%,qoq:+16%,需求端来看,单台AI服务器配备的SSD容量快速向上,叠加HDD供给偏紧、交期拉长,使得部分“冷数据”被动向QLC eSSD迁移,AI服务器需求持续提升。存储受益于AI需求,持续看好这轮存储行业上行周期。根据TrendForce集邦咨询最新调查,2025年第四季Server DRAM合约价受惠于全球云端供应商(CSP)扩充数据中心规模,涨势转强,并带动整体DRAM价格上扬,预计DRAM价格环比增长18-23%,HBM的ASP增长23%-28%。我们认为,随着服务器整机出货量年增幅度持续扩大,且因各CSP积极导入高效能运算架构以支援大型模型运算,Server单机DRAM搭载容量将随之提高,推升整体DRAM位元需求优于预期,导致供给短缺情况延续,持续看好本轮存储行业上行周期。该机构认为,当前时点是存储芯片赛道下一轮周期的新起点,在AI服务器需求高速增长叠加国产替代,看好国内存储产业链相关上市公司的投资机遇。
