Rambus posts record Q3 revenue of $218M, guides Q4 product revenue +34% YoY as DDR5 RCD ramp and AI server demand accelerate into 2027
Rambus delivered record Q3 2026 revenue of $218 million (+22% YoY) and record non-GAAP EPS of $0.84 (+35% YoY), driven by a new all-time high in product revenue of $114 million as DDR5 RCD adoption and companion chip shipments accelerated. Q4 guidance at the midpoint implies product revenue growth of 34% YoY and total 2026 revenue growth of approximately 18% over FY2025, with non-GAAP EPS growth of approximately 24%. Management flagged supply chain lead time extension as a structural constraint entering 2027 but confirmed it did not impact Q3 or Q4 results, and is pre-building inventory against a strengthening backlog.

Rambus is a global semiconductor company providing industry-leading chips and silicon IP for data-intensive computing systems, focusing on data center and artificial intelligence ('AI') infrastructure. As a pioneer with over three decades of advanced semiconductor design experience, Rambus is at the forefront of enabling the next era of AI-driven computing, addressing the critical challenges of signal and power integrity at increasingly extreme data rates in the data center, edge and client markets. We are a leader in high-performance memory subsystems, offering a balanced and diverse portfolio of products, IP and patents that maximize performance and security in computationally intensive systems. The ongoing proliferation of AI is placing unprecedented demands on computing infrastructure, requiring massive amounts of processor performance and extremely high memory bandwidth. As workloads grow in size and diversity, system performance becomes memory bound, making the memory interface technology a critical determinant of overall throughput. This persistent gap between processor performance and memory subsystem capabilities remains one of the largest bottlenecks in high performance compute systems. Rambus is well positioned to address these challenges. Leveraging our deep expertise in memory technology and innovative architectures, we provide industry-leading memory interface chips that enable the highest bandwidth, capacity and power efficient server memory modules, maximizing memory performance and reliability for the most demanding data-intensive workloads. Beyond the data center, server-class technologies are migrating into client devices to bring these same benefits to end-user systems, such as AI personal computers ('PCs'). Furthermore, the growing adoption of AI and heterogenous computing across diverse applications is creating significant opportunities for our silicon IP portfolio.
