Tucker Sean 4

What Happened Sean Tucker, Senior Vice President and Chief Scientific Officer of Vaxart, had 9,265 restricted stock units (RSU) shares withheld by the company to satisfy income tax withholding tied to vested RSUs. The withholding was reported as a disposition at $0.61 per share, resulting in $5,638 withheld/remitted on February 2, 2026. This was a tax-withholding/net settlement of vested RSUs, not an open-market sale or purchase.

Context This was a routine tax-withholding event associated with RSU vesting (a net settlement), not a discretionary sale or market purchase by the insider. Such withholdings reduce the insider’s share count but are common and do not necessarily indicate a change in the insider’s view of the company.
