Key Q&A
Q:Will there be a catch-up in revenue in Q2 to make up for the revenue lost in Q1 due to the supply chain issue?
A:The supply chain issue has been resolved, and the company expects strong recovery in Q2 and for the full year. The lower Q1 product revenue does not change the business trajectory, and the company expects to grow faster than the market in 2026.
Q:Can you quantify the revenue impact of the supply chain issue?
A:The revenue impact is estimated to be in the low double-digit million range in what is already a seasonally soft quarter. The company expects to build inventory by the end of Q1 and return to strong growth in Q2.
Q:How did the RCD market share finish for 2025?
A:The company ended 2025 with a mid-40% share for DDR5. The DDR5 market grew in importance, while DDR4 decreased in share. The company expects to continue growing faster than the market in 2026.
Q:Has the timeline and opportunity for MRDIMM changed with the Intel Diamond Rapids and AMD Venice platforms?
A:The timeline has not changed. The company expects MRDIMM to ramp towards the end of the year, depending on the rollout of platforms from Intel and AMD. The company is ready for the rollout.
Q:How does the company define the growth rate of the market, particularly for servers?
A:The company aligns with Gartner's view of 8% market growth for servers, though other sources suggest double-digit growth. The company remains prudent due to potential memory shortages and expects to grow faster than the market.
Q:What is the growth expectation for PMICs and new products?
A:New products grew from low single-digit contribution in early 2025 to upper single digits in Q4. In Q1 2026, new products are expected to contribute double digits to total product revenue, with PMICs being the largest contributor.
Q:What are the expectations for DIMMs per CPU in 2027?
A:The number of DIMMs per CPU is expected to grow on average, but the dynamic is complex and depends on application needs (e.g., high bandwidth vs. capacity). Supply constraints in memory make it difficult to predict exact numbers.
Q:What is the expected contribution of DDR5 Gen 3 RCD relative to Gen 1 and 2 in 2026?
A:Gen 3 is expected to grow and become the predominant version of DDR5 in 2026. Gen 4 will have limited adoption, and Gen 5 will depend on the introduction of next-generation platforms from Intel and AMD.
Q:Is there any reputational harm from the supply chain issue, and can the supply chain recover quickly?
A:There is no reputational harm as the issue was resolved quickly in collaboration with suppliers and customers. The supply chain is expected to recover by the end of Q1, enabling strong growth in Q2.
Q:Will there be material revenue contribution from MRDIMMs by the end of the calendar year?
A:Initial contribution from MRDIMMs is expected towards the end of the year, with the main contribution happening in 2027.
Q:What is the company's market share prospect for RCD and companionships?
A:The company has a mid-40% market share for DDR5 RCDs, with room to grow. Companionships are ramping steadily and provide additional revenue, with interoperability between RCD and PMIC being a key advantage.
Q:What is the company's position on SOCAMM2 opportunities?
A:The company is monitoring SOCAMM2 dynamics and sees an SPD opportunity. It aims to have solutions for every JEDEC standard module and will continue to develop chips to support this market.
Q:How much of the product business is not related to the server market?
A:The client market contribution is minimal, limited to the high-end client space. The vast majority of the business is in the data center space.
Q:Are there signs of a slowdown in new chip design starts that could impact the IP business?
A:No signs of a slowdown. The company is bullish on its IP portfolio, which is well-positioned for AI solutions and expected to grow in 2026.
Q:What is the company's approach to custom hardware for AI infrastructure?
A:The company focuses on a narrow portfolio (e.g., PCIe, CXL, HBM, GDDR, and security IP) tailored for high-end data center applications. It supports a large number of customers developing custom chips for AI and server infrastructure.
Q:Are there memory supply constraints impacting customers' ability to fulfill demand?
A:The company hears from customers that server demand is solid but constrained by memory supply. Lead times are lengthening, and the company remains prudent in its market potential estimates.
Q:What are the expectations for product gross margins in 2026?
A:Product gross margins are expected to remain in the 60-65% range, consistent with the past three years. The company will continue disciplined pricing and manufacturing cost savings.
Q:Review of Unclear Management Responses
A:Management avoided providing specific numbers or clear details on the exact number of DIMMs per CPU expected in 2027, citing the complexity of the dynamic and supply constraints. Additionally, they did not provide a precise timeline for SOCAMM2 opportunities beyond general monitoring and potential SPD contributions.

Rambus Inc. (RMBS) Q1 2026 Earnings Call Transcript
Unknown4-27
The earnings call reveals a mixed outlook. Positive aspects include a 10% YoY revenue increase and improved gross margins. However, geopolitical and macroeconomic risks, along with ASC 606 complexities, present uncertainties. EPS growth is strong, but the absence of discussions on operational updates and returns limits clarity. With no new partnerships or guidance changes, and considering the lack of market cap data, the stock reaction is likely neutral.
