存储芯片制造商们交出了耀眼的成绩单。SK海力士第二季度营收达79.32万亿韩元，同比增长257%，营业利润60.54万亿韩元同比暴增557%，净利润更是飙升至93.92万亿韩元，同比增长1242%[1]。三星电子的表现同样亮眼，销售额171.50万亿韩元，同比增长130%，营业利润89.49万亿韩元同比激增1813.83%，净利润71.27万亿韩元同比增长1344.46%[1]。然而股市的反应却截然相反——SK海力士股价单日暴跌11%-13%，市值蒸发约20万亿韩元[1]。
存储产业链的上游企业也在这波盈利狂潮中获益。国内企业江波龙上半年净利润同比增长62204%-74394%，佰维存储增长3200%-3422%，德明利增长近50倍[1]。但这些巨大的利润增幅并未惠及下游产业。2026年二季度手机DRAM内存价格环比涨幅突破80%，旗舰机型BOM成本同比涨幅接近50%[1]，这给手机和PC厂商带来了沉重的成本压力。
面对存储芯片价格的大幅上涨，下游厂商开启了集体抵抗。OPPO与vivo正式拒绝了三星电子2026年第三季度存储产品的报价，国内TOP6手机厂商中多家明确拒绝涨价要求[1]。此外，存储产业链已出现分化迹象，华强北16G DDR4内存条单月跌去约35%，从700多元跌至450元[1]。与此同时，SK海力士已完成与10余家企业的长期供货协议签署，2026年HBM产能售罄，2027年大部分产能已被预订[1]，显示上游厂商正在通过长期合约锁定高价。
SK Hynix and Samsung Electronics have reported blockbuster financial results, with their memory chip divisions reaching historic profitability levels. SK Hynix posted second-quarter revenue of 793.2 billion Korean won, up 257% year-over-year, with operating profit surging 557% to 605.4 billion won and net profit skyrocketing 1,242% to 939.2 billion won [1]. Samsung Electronics reported sales of 1.715 trillion won, up 130% annually, while operating profit jumped 1,813.83% to 894.9 billion won and net profit climbed 1,344.46% to 712.7 billion won [1]. However, despite these record earnings, SK Hynix shares plummeted 11–13% in a single trading session, wiping approximately 200 trillion won from its market value [1].
The surge in memory chip profits has extended across the industry supply chain. Domestic storage companies have also achieved explosive growth, with Longsys reporting net profit increases of 62,204% to 74,394% in the first half of the year; Biwin Memory saw growth of 3,200% to 3,422%; and Deming Profit increased nearly 50-fold [1]. Meanwhile, handset manufacturers face mounting pressure from soaring component costs. DRAM prices for smartphones jumped more than 80% sequentially in the second quarter of 2026, and memory costs for flagship device models have climbed roughly 50% year-over-year in bill-of-materials expenses [1]. In response, multiple top Chinese smartphone brands, including OPPO and vivo, have formally rejected Samsung's pricing for storage products scheduled for the third quarter of 2026 [1]. The broader handset sector has coalesced around resistance to price increases, setting the stage for intensified negotiations within the industry supply chain [1].
SK Hynix has completed long-term supply agreements with over ten enterprises, with its 2026 HBM production capacity already sold out and most of its 2027 output pre-booked [1]. Spot market pressures are also evident: 16GB DDR4 memory modules in Huaqiangbei dropped roughly 35% month-over-month, falling from above 700 yuan to 450 yuan [1].
