Director Victor Peng awarded 168 RSUs in Rambus (RMBS) stock compensation

Rhea-AI Filing Summary

Rambus Inc. director Victor Peng reported an equity award of 168 shares of common stock. The award is structured as restricted stock units granted at a price of $0.00 per share, reflecting a compensatory grant rather than an open-market purchase.

All 168 RSUs are scheduled to vest on April 1, 2026, or the first business day thereafter. Each RSU converts into one share of Rambus common stock at vesting, so Peng’s ownership will increase as the units vest, assuming continued service and satisfaction of the vesting conditions.
