- Q2 2025 Product Revenue: $81M (+43% YoY)

Are They Coming Off a Tough Comparable?
- Yes, but not the toughest: FY2025 was a record year (+41% product revenue YoY), but Q1 2026 was impacted by a supply chain issue, making Q2 2026 a more normalized comp. Q2 2025 was a strong quarter, but the company is guiding for another double-digit YoY increase in Q2 2026.
Management Commentary — Key Themes
- On Product Revenue: "We expect to deliver double-digit product revenue growth in the second quarter."
- On Supply Chain: "Supply chain issue is behind us...revenue for Q2 is guided at 11% over Q1...continue to expect to grow sequentially after that."
- On Market Share: "We exited '25, we were mid-40% share. There's no indication that we are not going to continue on that trajectory."
- On MRDIMM: "Ramp starting in 2027 in earnest...SAM at this point in time, which we still value at about $600 million."
- On Companion Chips: "Newer products...contributing low double-digit percent of our total product revenue during the first quarter. We would expect it to be roughly the same in the second quarter...expect maybe to exit the year mid-double-digit of product revenues on -- coming from our new chips."
- On Silicon IP: "Very good traction...continue to expect this business to grow 10% to 15% a year based on that."
- On Seasonality: "Typically, our second half is stronger than our first half."

Conclusion
Rambus enters Q2 2026 with strong momentum, guiding for double-digit sequential and YoY growth in product revenue, continued market share gains, and increasing contribution from new companion chips. The company is coming off a record FY2025 but had a Q1 2026 supply chain headwind, making Q2 a more normalized comp. Key factors to watch are the pace of product revenue recovery, supply chain normalization, MRDIMM/Gen 5 ramp timing, and ongoing strength in the silicon IP business. Management expects a stronger H2, with new platform launches and further content expansion driving growth.
