Rambus NASDAQ: RMBS reported record third-quarter revenue, non-GAAP earnings and operating cash flow, as demand for its memory-interface products and intellectual property continued to benefit from AI infrastructure investment. Third-quarter revenue rose 22% year over year and 5% sequentially to $218 million. Product revenue reached a record $114 million, increasing 22% from a year earlier and 15% from the prior quarter. The company said its DDR5 registered clock driver, or RCD, products and adoption of newer-generation offerings supported the performance. Non-GAAP net income was $91.7 million, producing non-GAAP earnings per share of $0.84, up 35% year over year and 10% sequentially. Rambus also generated a record $102 million in cash flow from operations during the quarter. Fourth-Quarter outlook calls for further product growth. For the fourth quarter, Rambus expects revenue of $227 million to $233 million. Product revenue is projected at $127 million to $133 million, which would represent a 34% year-over-year increase and a 14% sequential increase at the midpoint of the range. The company forecast fourth-quarter royalties revenue of $68 million to $74 million and contract and other revenue of $26 million to $32 million. Contract and other revenue is primarily Silicon IP revenue, though Rambus noted that some Silicon IP revenue is included in royalties. Rambus expects non-GAAP earnings per share of $0.84 to $0.92 for the fourth quarter, based on a 16% non-GAAP tax rate and 109 million diluted shares outstanding. At the midpoint, that outlook would represent 30% year-over-year EPS growth and 5% sequential growth. Chief Financial Officer Sumeet Gagneja said the midpoint of the company's fourth-quarter outlook implies revenue growth of about 18% for 2026 compared with 2025, including approximately 24% growth in product revenue. Rambus also expects full-year non-GAAP earnings per share to grow about 24%. AI demand drives memory and IP investments. CEO Luc Seraphin said AI training, inference and agentic AI are increasing demand for more sophisticated memory and infrastructure architectures. He said always-on workloads are placing additional demands on CPUs, raising CPU-to-GPU ratios and increasing requirements for main-memory bandwidth and capacity across data centers.

The company said its sixth-generation RCD supporting DDR5 9600 is now broadly sampling with customers. Rambus also introduced a power-management integrated circuit for upcoming LPDDR6 SOCAMM2 memory modules, extending its server-memory roadmap into LPDDR6. Seraphin said the LPDDR6 SOCAMM2 product is expected to reach the market around 2028. He characterized SOCAMM as targeting a smaller portion of AI infrastructure, while saying conventional CPU systems using standard DIMM memory configurations will remain the majority of the market. During the question-and-answer session, Seraphin said Rambus's companion-chip business represented a low-double-digit percentage of product revenue at the start of the year and has continued to grow sequentially. MRDIMM shipments remain modest, he said, consisting of qualification and preproduction activity, though the company still sees a $600 million total opportunity over time. Rambus also reported design wins in its Silicon IP portfolio, including next-generation high-bandwidth memory, or HBM, programs. The company cited growing interest in PCIe controller and switch IP for AI scale-up and scale-out connectivity, as well as demand for hardware-based security products. The company introduced a root-of-trust security solution designed for AI and data-center deployments that supports the Caliptra specification. Rambus also announced a strategic investment and collaboration with ChipAgents, which Seraphin said could help accelerate chip and IP development through AI-native design flows. Capital returns and supply planning. Rambus completed a $100 million accelerated share repurchase during the quarter. Total share repurchases were $135 million, which, along with the repurchases, more than offset operating cash flow and reduced cash, cash equivalents and marketable securities to $777 million at quarter-end from $825 million in the prior quarter. Gagneja said Rambus intends over time to return 40% to 50% of free cash flow to shareholders while continuing to invest in growth initiatives. The company increased inventory by $12 million in the third quarter to support future product ramps and provide customers with supply assurance. Executives said supplier lead times have increased, but the company's third-quarter results and fourth-quarter guidance were not affected by supply constraints. Seraphin said Rambus has used its balance sheet and supplier relationships to prepare for tighter supply conditions. While Rambus has not increased customer lead times, he said customers are placing backlog orders earlier than they did several quarters ago, improving the company's visibility into demand. For 2027, Rambus expects demand to strengthen, although executives said seasonality between the first and second halves of the year is likely to continue. The company expects supply to remain tight and said it is working closely with suppliers to support anticipated customer demand. About Rambus (NASDAQ:RMBS).
