Insights

Director received time-based RSU grant with potential accelerated vesting.

Director Walters Happy David was awarded 58,917 restricted stock units in HYPERION DEFI, INC. stock. The grant is compensation-related, not an open-market purchase, and therefore carries limited signaling value about the director’s view of the stock price.

The RSUs vest fully on the earlier of June 30, 2027 or the 2027 annual stockholder meeting, which ties the award to continued Board service. Vesting accelerates if a defined corporate transaction occurs or if Board service ends other than by the director’s own decision to step down, providing change-in-control and involuntary departure protection.
