RAMBUS INC Q3 FY2026 earnings call

• Record Financial Performance: Delivered record quarterly product revenue ($114M) and non-GAAP earnings ($0.84 EPS), exceeding guidance ranges driven by strong AI infrastructure demand.
• Product Roadmap Execution: Achieved broad sampling of the sixth-generation RCD supporting DDR5-9600; expanded portfolio with industry-leading PMIC for LPDDR6 SoCAM2 to enhance power efficiency for AI workloads.
• Silicon IP Growth: Secured key design wins in next-gen HBM, PCIe controller/switch IP, and hardware security solutions (Eliptra/Root of Trust); deepening engagement with hyperscalers on custom silicon architectures.
• Strategic Partnership: Announced collaboration with ChipAgents to leverage agentic AI design platforms, accelerating chip/IP development speed and engineering productivity.
• Capital Allocation: Completed a $100 million accelerated share repurchase; committed to returning 40-50% of free cash flow to shareholders while investing in growth.
• Supply Chain Management: Leveraged strong balance sheet to increase inventory by $12 million to mitigate tightening supply chain lead times and ensure customer supply assurance.

Total Revenue: $218 million (up 22% YoY, 5% sequentially). Product Revenue: $114 million (up 22% YoY, 15% sequentially), representing approximately 52.3% of total revenue. Royalty Revenue: $77 million, representing approximately 35.3% of total revenue. Contract and Other Revenue (primarily Silicon IP): $27 million (up 35% YoY, 13% sequentially), representing approximately 12.4% of total revenue.

• Q4 Total Revenue: Expected between $227 million and $233 million (midpoint implies ~34% YoY growth).
• Q4 Product Revenue: Expected between $127 million and $133 million (midpoint implies >30% YoY growth).
• Q4 Royalty Revenue: Expected between $68 million and $74 million.
• Q4 Contract & Other Revenue: Expected between $26 million and $32 million.
• Q4 Non-GAAP Operating Profit: Expected between $103 million and $113 million.
• Q4 Non-GAAP EPS: Expected between $0.84 and $0.92 (midpoint implies ~30% YoY growth).
• Full Year Outlook: Expects 2026 full-year revenue to grow ~18% over 2025, with product revenue growing ~24% and non-GAAP EPS growing ~24%.

• Supply Chain Constraints: Lead times from suppliers are increasing; tight foundry capacity requires proactive inventory building and balance sheet leverage to mitigate risks.
• Technology Adoption Pace: MRDIMM ramp is expected to be shallower than previous generations due to single-platform dependency and initial market stumbles.
• Memory Economics: Customers may decrease module capacity per unit (despecking) despite increasing module counts, impacting content dynamics.
• Security Threats: Agentic AI deployments expand the attack surface, necessitating robust hardware-based security foundations like Eliptra.

Q: Kevin Corrigan asked about the drivers of the strong Q4 product revenue guidance (34% YoY midpoint) and the outlook for MRDIMM adoption compared to competitors.

A: Luc Seraphin attributed the growth primarily to new generation RCDs and companionship ramps, noting MRDIMM shipments remain modest. He explained that MRDIMM’s ramp will be shallower than standard DIMMs because it relies on a single platform launch and involves initial technology adoption hurdles. However, he remains confident in the long-term $600 million opportunity as customers navigate memory economics and platform transitions.

Q: Gary Mobley inquired about the visibility into 2027 seasonality and the potential for long-term development arrangements with hyperscalers developing custom silicon via Silicon IP.

A: Luc Seraphin stated that demand is strengthening for 2027 with better backlog visibility, expecting continued H2 seasonality but overall healthy growth. Regarding Silicon IP, he highlighted deepening architectural engagements with hyperscalers on complex chips (e.g., PCIe7, HBM4), suggesting future growth could come from organic expansion, acquisitions, or system-level partnerships enabled by agentic AI tools.

Q: Sebastien Naji requested details on the dollar content increase of the new LPDDR6 PMIC versus the earlier SoCAM2 announcement and its expected revenue timeline.

A: Luc Seraphin noted that exact content figures are withheld until final specs are released but confirmed that SoCAM2’s power management complexity increases dollar content per module compared to Gen 1. He clarified that SoCAM2 targets a niche AI infrastructure segment and will likely hit the market around 2028, serving as a strategic complement to standard memory rather than a cannibalizer.

Q: Mark Lipacis asked about supplier lead times, customer lead times, and whether downstream customers are increasing inventories given tight supply.

A: Luc Seraphin confirmed that supplier lead times are increasing, prompting Rambus to build inventory using its balance sheet. Customer lead times have not increased yet, though the company monitors this closely. He clarified that they do not see customers building significant inventory themselves; instead, customers are placing backlogs earlier, which improves Rambus’s visibility and allows for closer coordination to meet demand.

Q: Tristan Jara questioned the sustainability of accelerating demand into 2027 amidst supply constraints and asked about the relative content opportunity between x86 CPUs and ARM-based TPUs.

A: Luc Seraphin affirmed that demand is strong going into 2027 and supply will remain tight, requiring weekly engagement with supply partners to fulfill orders. Regarding architecture, he emphasized an aggregate view: while head nodes offer SoCAM opportunities, the majority of growth comes from standard CPU servers with traditional memory subsystems. He views SoCAM as complementary to standard DIMMs, ensuring Rambus serves heterogeneous systems as AI infrastructure expands.
