Rambus Initiates $100 Million Accelerated Share Repurchase Program

SAN JOSE, Calif.-- August 5, 2026 -- Rambus Inc. (NASDAQ: RMBS), a premier chip and silicon IP provider making data faster and safer, today announced that it initiated an accelerated share repurchase program with Mizuho Markets Americas LLC, through its agent Mizuho Securities USA LLC (“Dealer”) to repurchase an aggregate of approximately $100 million of its common stock.

“This accelerated share repurchase reflects our confidence in the business and reinforces our commitment to disciplined capital allocation,” said Luc Seraphin, president and chief executive officer at Rambus. “Supported by the strength of our balance sheet and continued cash generation, we remain focused on increasing stockholder value while investing in the long-term growth of the company.”

Under the accelerated share repurchase program, Rambus will pre-pay $100 million to Dealer and receive an initial delivery of approximately 796,000 shares of its common stock. The final number of shares to be repurchased will be determined based on the volume-weighted average price of Rambus common stock during the term of the transaction, less a discount. The program is expected to be completed by the end of the third quarter of 2026.

The accelerated share repurchase program is part of the broader share repurchase program previously authorized by the Rambus Board of Directors.
