Knox David R. 4

What Happened

• David R. Knox, Chief Financial Officer of Hyperion DeFi, Inc. (HYPD), disposed of 20,831 shares on 2026-03-30 as part of a tax withholding arrangement. The Form 4 reports the shares at $0.00 (no cash proceeds shown) and lists the transaction type/code as F (payment of exercise price or tax liability).
• This was not an open-market sale but shares withheld to satisfy tax obligations arising from the vesting and settlement of previously granted restricted stock units (RSUs), a routine administrative action rather than a directional trade.

Key Details

• Transaction date: 2026-03-30
• Reported price: $0.00 per share; total cash proceeds reported: $0
• Shares involved: 20,831 shares withheld/disposed

Context

• Withholding shares to cover taxes on vested RSUs is a common administrative practice and does not necessarily reflect the insider’s view of the company’s stock. For retail investors, purchases or open-market sales tend to be more informative signals of insider sentiment than routine tax-withholding dispositions.
