RAMBUS INC Q1 FY2025 earnings call

Management Statement and Operational Highlights

• Rambus had an excellent start to FY 2025, achieving record product revenue in memory interface chips.
• The company is aggressively driving its product development roadmap for signal and power integrity solutions in data center memory architectures.
• The patent licensing business is predictable, providing financial stability. The robust balance sheet and strong cash from operations ($77 million in Q1) enable navigation of macroeconomic uncertainty.
• Progress on new products: Server PMICs and MRDIMM 12800 chipset are in development, with early shipments for server and client applications.
• AI drives demand for chips and IP, with new crypto manager security IP introduced in March to address expanded customer needs and security requirements.

Segment Performance

• Memory Interface Chips: In Q1, memory interface chips drove top-line growth with record revenue of $76 million, up 52% year-over-year. This segment contributes significantly to the overall revenue.
• Silicon IP: AI drives design win momentum. Royalty revenue was $74 million, licensing billings were $73.3 million, and contract and other revenue was $16.4 million in Q1. The silicon IP business is lumpy due to customer program timing, but AI and data center evolution continue to drive demand.

Guidance

• Q2 revenue is expected to be between $167 million and $173 million.
• Royalty revenue is projected to be between $67 million and $73 million, and licensing billings between $64 million and $70 million.
• Q2 non-GAAP total operating costs (including COGS) are expected to be between $90 million and $94 million.
• Non-GAAP operating results for Q2 are expected to be between a profit of $73 million and $83 million.
• Anticipated Q2 non-GAAP earnings per share range between $0.57 and $0.64.

Risks

• Geopolitical and macroeconomic uncertainties, including potential impacts of tariffs. There is limited visibility on the potential impacts of tariffs beyond the current quarter, and the company is actively monitoring and discussing with customers and suppliers.

Question and Answer

• Q: Gary Mobley on market trends and ASC 606 impact A: Luc Seraphin discussed that the market for memory interface chips is expected to grow mid to high single-digit this year, considering factors like socket configurations and AI vs standard servers. Desmond Lynch mentioned a patent agreement renewal led to upfront revenue recognition under ASC 606, with billings to follow in later quarters.
• Q: Aaron Rakers on tariffs and product growth A: Luc Seraphin stated there is no direct impact of tariffs on operations currently, but they are monitoring indirect impacts. Desmond Lynch noted the order backlog is over 90% covered and no pull-forward of demand from customers has been observed.
• Q: Blayne Curtis on tariff order momentum A: Desmond Lynch said the order backlog is well-covered, with normal shipping patterns expected through the quarter, and no pull-forward of demand is seen.
• Q: Mehdi Hosseini on gross margin and Silicon IP A: Desmond Lynch expected gross margin to improve in the second half due to better product mix and manufacturing cost savings. On Silicon IP, the business is lumpy as it depends on design starts and tape-outs, with HBM4 activity starting months ago for future chip rollouts.
• Q: Natalia Winkler on ARM vs x86 and client products A: Luc Seraphin said Rambus is agnostic to processor type, with the product line unchanged regardless of x86 vs ARM shift. On client products, the Client Clock Driver is sampling to customers with availability end of this year/beginning next year in low volumes.
• Q: Kevin Cassidy on Silicon IP and MRDIMM A: Desmond Lynch expected Silicon IP revenue to be relatively flat in Q2. Luc Seraphin discussed MRDIMM adoption is driven by capacity and bandwidth needs, used in high-end systems like AI deployments.
• Q: Tristan Gerr on operating margin and pricing A: Desmond Lynch expected operating margin to improve with product mix and cost savings. Price renegotiation is normal mid-single-digit erosion, in line with historical cycles.
