- Rambus dropped 7.6% on Friday, closing at $115.31, then held steady in after-hours trading
- The decline came after a sharp rally fueled by new bullish sell-side coverage
- Attention shifts to Rambus’ results on Feb. 2 and its forecast for AI-driven memory demand
Rambus Inc shares fell 7.6% Friday, closing at $115.31 after swinging between $113.13 and $123.50 during the session. In after-hours trading, the stock edged slightly lower to $114.96, while the Nasdaq managed a modest gain heading into the weekend. 1
The pullback halted a rally that had driven RMBS up more than 22% over the past week, pushing it close to a 52-week high of $131.12, per InvestingPro data. On Thursday, William Blair kicked off coverage with an “Outperform” rating, spotlighting Rambus as a top player in DRAM memory solutions and emphasizing its role in DRAM interface chips for server memory modules. 2
Why it matters now: the stock is currently priced as if a strong quarter is guaranteed, but Friday’s drop revealed how fast that optimism can evaporate. With U.S. markets closed on Saturday, investors face Monday wondering if buyers will step back in or pull away ahead of the earnings report.
Rambus plans to release its fourth-quarter and full-year earnings on Feb. 2, according to its investor relations page. A webcast will follow at 5:00 p.m. EST. 3
William Blair analyst Sebastien Naji linked the broader memory sector to rising AI demand. “Advancements in AI compute are increasingly hindered by memory bottlenecks,” he noted in a firm statement unveiling the initiations, which also covered Micron Technology and Silicon Motion. 4
Bulls on Rambus are banking on two key factors: increased memory content in servers and data centers, plus consistent licensing revenue from high-bandwidth memory and security IP. William Blair’s latest note echoed this view, highlighting that rising average selling prices and strong data-center demand might drive growth.
That next catalyst, however, could swing either way. Any sign of weaker server builds, cooling licensing growth, or customers pushing out purchases might hit especially hard after a run that’s left barely any margin for mistakes.
For traders, the focus this week boils down to a single date. On Feb. 2, Rambus must back its AI-memory narrative with solid numbers — and sustain it through guidance.
