Did RMBS Beat Earnings? Q4 2025 Results
Rambus closed out fiscal 2025 with a notably strong fourth quarter, posting non-GAAP diluted EPS of $0.68 against a consensus estimate of $0.55, a beat of 24.77%, while revenue of $190.24 million edged ahead of the $188.06 million estimate and grew 18.1% year over year. The primary engine behind the outperformance was a record quarter for product revenue at $96.78 million, fueled by the company's continued leadership in DDR5 Registered Clock Drivers and expanding contributions from newer products, alongside royalty revenue climbing to $71.68 million from $58.21 million a year ago. Full-year operating cash flow reached $360.00 million, with the balance sheet ending the period at $761.80 million in cash and marketable securities. Looking into Q1 2026, Rambus guided product revenue of $84.00 to $90.00 million and royalty revenue of $61.00 to $67.00 million, though the outlook was tempered somewhat by a disclosed supply chain disruption and the announced resignation of CFO Desmond Lynch, with John Allen stepping in as interim chief financial officer.
