Rambus Q2 Earnings Call Highlights

Rambus NASDAQ: RMBS reported record second-quarter fiscal 2026 revenue and non-GAAP earnings, supported by growth in its memory-interface chip business and contributions from royalties and silicon IP. The company’s revenue surpassed $200 million for the first time, while management said demand trends tied to AI infrastructure, CPU-based servers and rising memory requirements continue to support its outlook. Second-quarter revenue totaled $207.4 million, up 20% from a year earlier and 15% sequentially. Non-GAAP net income was $84.4 million, or $0.77 per diluted share, representing year-over-year growth of 24% and sequential growth of 21%. “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,” Chief Executive Officer Luc Seraphin said. He said the company’s results were driven by record product revenue and diversified revenue streams. Product revenue was $99.2 million, rising 22% year over year and 13% from the prior quarter. Royalties revenue was $84.2 million, while contract and other revenue was $24 million, consisting primarily of silicon IP. Rambus noted that some silicon IP revenue is included in royalties revenue rather than contract and other revenue. Seraphin attributed product growth to Rambus’ DDR5 registered clock driver, or RCD, business, along with traction in newer products. The company introduced complete chipsets for DDR5 9600 client and server memory modules during the quarter, including a DDR5 9600 RDIMM chipset built around its sixth-generation RCD and PMIC5030 power-management product. The company is also pursuing new memory-module architectures, including MRDIMM and LPDDR5X SOCAMM2. Seraphin said these products are intended to address differing performance, capacity and power requirements as AI infrastructure becomes more varied. Management expects MRDIMM’s contribution in the fourth quarter to be minimal, with a more material contribution expected in 2027 as CPU platforms ramp. Seraphin said Rambus is continuing to ship products for early customer system builds. On LPDDR-based server modules, Seraphin said the company views SOCAMM as complementary to DDR-based server memory rather than a replacement. DDR is expected to remain dominant in systems requiring server-grade scale, capacity, reliability and serviceability, while LPDDR may be used where power efficiency is particularly important, he said. Rambus said AI workloads are increasing demand for memory capacity, bandwidth, power efficiency and secure connectivity. Seraphin said agentic AI applications are helping drive demand for CPU-based servers used for orchestration, data management and real-time execution. In silicon IP, the company cited customer traction and design wins across hyperscalers, custom silicon comp...
