Record Revenue and a New CFO: Rambus Leans Into the AI Inference Wave Even as the Tape Caves
Q2 2026 revenue cracks $200M for the first time; product revenue jumps 22% on memory-interface strength, but the stock sits 46% below its June peak.

Record Quarter, New Face, Simpler Metric
Rambus turned in something genuinely new this quarter: a $207.4 million revenue print that nudges past the symbolic $200 million mark for the first time. More notable than the number itself is the way it arrived — record product revenue of $99.2 million, up 22% year-over-year, alongside a healthy royalty and silicon IP mix. The company is leaning into AI infrastructure and inference at a moment when CPUs are regaining prominence in agentic workloads. And it did this while welcoming a new CFO, Sumeet Gagneja, who used his first call to drop a 2-decade-old disclosure metric — licensing billings — in favor of a simpler ASC 606 revenue basis.The Agentic Engine
Revenue crossed the $200M bar for the first time in Q2 2026. Non-GAAP EPS of $0.77 was up 24% year-over-year and 21% sequentially, and the company guided Q3 revenue to $210–216M with product revenue growing another 14% sequentially. Luc Seraphin’s opening line set the tone: “Rambus had an excellent second quarter. Delivering a new all-time high in revenue and non-GAAP earnings, and beating the high-end of our guidance ranges.” — Luc Seraphin, Chief Executive Officer · 2026-07-27 The 10-Q shows the trend clearly: Total revenue has climbed from $167M in Q1 2025 to $207M in Q2 2026, a 20% year-over-year gain. Importantly, the mix is shifting — product revenue is now the largest line, with royalties and silicon IP diversifying the base. Luc linked the better-than-expected demand to the shift from training to inference and agentic workloads: “AI continues to drive a fundamental evolution in computing, as inference and agentic use cases scale workloads are becoming more diverse, more persistent, and more memory intensive.” — Luc Seraphin, Chief Executive Officer · 2026-07-27 That framing dovetails with a first-time keyword this quarter: key value cache. Agentic AI requires low-latency memory for state management, which is exactly why Rambus sees CPU-based servers running at higher channel counts and, increasingly, MRDIMMs. The company also reiterated its view on CXL: it’s an interconnect protocol, not a near-term product, and Rambus will play through silicon IP rather than a memory-expansion chip. That stance hasn’t changed from prior quarters, but the emphasis on AI scale as the demand driver is sharper. It’s a continuation of a thesis Luc voiced three months earlier: “We do see demand continue to grow for standard servers, which is good for us with agentic AI in particular.” — Luc Seraphin, Chief Executive Officer · 2026-04-27Silicon IP, Hyperscaler Wins, and the MRDIMM Swing Factor
Rambus also highlighted a new design win with a Tier 1 U.S. hyperscaler for next-generation HBM controllers. In Q&A, Luc clarified it is an IP win, not a product win: “it is an IP design win for a company that designs a product.” — Luc Seraphin, Chief Executive Officer · 2026-07-27 That’s exactly the kind of design win that compounds as AI custom silicon proliferates. The company also expanded its PCIe 7.0 switch IP portfolio—a signal that it wants a seat at the scale-up and scale-out table. Combined with the companion chip ramp, which Luc said should exit the year in the mid-double-digit percentage of product revenue, this points to a broadening product story. The biggest swing factor remains MRDIMM. Management has been consistent about timing—material contributions begin in 2027, when the next-gen AMD and Intel platforms ramp. In February, Luc said: “Our MRDIMM to ramp towards the very end of the year at this point in time.” — Luc Seraphin, Chief Executive Officer · 2026-02-02 This quarter he added that Q4 contribution will be minimal: “The contribution for Q4 is going to be minimal. We continue to ship to our customers, you know, for these early system buildups and a more material contribution is going to happen in 2027 when both platforms from the CPU guys ramp in the market.” — Luc Seraphin, Chief Executive Officer · 2026-07-27 The supply chain is the other side of that equation. Management is building strategic inventory in anticipation of tightness that extends into 2027. On the demand side, the company is confident, but prudence on platform timing and supply is the watchword. Sumeet Gagneja, on his first call, framed the financial priority this way:As CFO, my focus is straightforward. Drive profitable growth through disciplined financial execution, allocate capital thoughtfully and provide shareholders with transparent and consistent communication.
