Hyperion DeFi CEO Jung Hyunsu Withholds 40,000 Shares for Taxes

What Happened

• Jung Hyunsu, Chief Executive Officer and Chief Investment Officer of Hyperion DeFi, Inc. (HYPD), had 40,000 shares reported as disposed on Aug 16, 2026 through share withholding to satisfy tax withholding obligations related to the vesting and settlement of restricted stock units (RSUs).
