The chip and semiconductor IP company reported revenue of $180.19 million, edging past the $179.94 million consensus estimate by 0.14% and representing 8.1% growth from the year-ago period, with product revenue climbing 15% year over year to $88.00 million on sustained demand for memory interface chips tied to AI infrastructure buildouts. Non-GAAP diluted EPS of $0.63 came in 0.99% below the $0.64 consensus, as research and development expenses climbed to $50.23 million from $42.62 million a year ago, compressing non-GAAP operating margin to 42% from 46%. An analyst downgrade citing tightening DRAM supply conditions added pressure on the stock following the report. Looking ahead, Rambus guided Q2 total revenue of $186.00 million to $204.00 million, with product revenue of $95.00 million to $101.00 million reflecting continued confidence in AI server demand driving its expanding chipset portfolio.

Key Takeaways

  • • 15% year-over-year growth in product revenue driven by AI infrastructure demand
  • • Growth of AI inference and agentic workloads in data centers driving demand for higher memory bandwidth
  • • Strong cash generation of $83.2 million from operating activities
  • • Contract and other revenue increased to $22.6 million from $16.4 million year over year

RMBS Forward Guidance & Outlook

For Q2 2026, Rambus expects licensing billings of $76–$82 million, royalty revenue of $72–$78 million, product revenue of $95–$101 million, and contract and other revenue of $19–$25 million. GAAP operating costs and expenses are expected between $127–$131 million, and non-GAAP operating costs and expenses between $110–$114 million. The outlook assumes a non-GAAP tax rate of 16%, a diluted share count of 110 million, and excludes stock-based compensation expense of $15.7 million and amortization of acquired intangible assets of $1.5 million. Interest and other income is expected to be approximately $7 million.
