| Item 1.01. | Entry into a Material Definitive Agreement. |
On August 4, 2026, Rambus Inc. (NASDAQ: RMBS) (the “Company”) entered into a Supplemental Confirmation under the Master Confirmation (the “Master Agreement,” and together with the Supplemental Confirmation, the “ASR Agreement”) with Mizuho Markets Americas LLC, through its agent Mizuho Securities USA LLC (“Dealer”), pursuant to an accelerated share repurchase program (the “ASR Program”) under which the Company will repurchase shares of the Company’s common stock for an aggregate purchase price of approximately $100 million (the “Shares”). The ASR Program is part of a broader share repurchase program previously authorized by the board of directors of the Company.
Under the ASR Agreement, the Company will pre-pay $100 million to Dealer and will receive an initial delivery of approximately 796,000 of the Shares. The final number of Shares to be repurchased by the Company under the ASR Program will be determined based on the volume-weighted average price of the Company’s common stock during the term of the transaction, less a discount. The ASR Program is expected to be completed by the end of the third quarter of 2026.
