Revenue Acceleration/Inflection
Guidance Update
- Rambus operates three main businesses: patent licensing (generating $210 million annually with a 100% margin), Silicon IP (which was $120 million last year and is growing 10%-15% annually with a 95% gross margin), and a fabless IC business (expected to reach $340 million this year, growing 40% over last year with a 61%-63% gross margin).
- The company anticipates significant market expansion in memory interface chips, with the total addressable market (TAM) growing from an $800 million base to $1.4 billion with DDR5 companion chips, and further expansion from high-end client systems and MRDIMM technology.
- MRDIMM technology is projected to multiply Rambus's content by a factor of four per module and is expected to ramp with new Intel and AMD platforms by the end of 2026 or beginning of 2027.
- Rambus maintains a strong financial model, generating $300 million in cash from operations over the last 12 months, with an expected operating margin of 40%-45%, and aims to return 40%-50% of free cash flow to investors.
- The Silicon IP business is strategically focused on security (comprising half of the business) and high-speed interfaces, with minimal exposure to China, representing less than 5% of revenue.

Guidance Update
- Rambus's business is comprised of three segments: Patent Licensing ($210 million annual revenue, 100% gross margin), Silicon IP ($120 million last year, 95% gross margin, growing 10-15% annually), and ICs (projected $340 million this year, 61-63% gross margin, growing 40% over last year).
- The company sees significant growth in its IC business, fueled by data center demand and the transition to DDR5 memory, expanding the total addressable market (TAM) for interface and companion chips to $1.4 billion.
- Future growth is anticipated from MRDIMM solutions, which are expected to multiply Rambus's content per module by four and add an additional $600 million to the TAM, with platform ramps projected for late 2026 or early 2027.
- Rambus maintains a strong financial model, generating $300 million in cash from operations over the last 12 months, targeting a 40-45% operating margin, and committing to return 40-50% of free cash flow to investors.

- The company identifies significant market expansion opportunities, including the DDR5 transition adding $600 million in companion chips to the base $800 million interface chip market, and the upcoming MRDIMM technology which could add another $600 million to the total addressable market and is expected to ramp by late 2026/early 2027.
- AI is a catalyst for high-end traditional servers and AI inference is a growth driver for Rambus, as its interface technology is agnostic to processor types. The Silicon IP business is strategically focused on security and high-speed interfaces, with security representing half of that business.
- Rambus's financial model is characterized by strong cash generation, with $300 million in cash from operations over the last 12 months and an expected operating margin of 40%-45%. Capital allocation priorities include organic growth, strategic acquisitions, and returning 40%-50% of free cash flow to investors.
