Jeroen Nicolaas Grasman: trading record in brief
Jeroen Nicolaas Grasman is a declared insider of Vaxart, Inc., with filings sourced from SEC (Form 4). Over a trading history stretching from 19 May 2025 to 19 May 2026, the count stands at 3 filings.
None of the filings is a plain purchase or sale on the open market; they cover grants, option exercises and other movements. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
On 21 May 2026 came the latest disclosure, a share grant for €16k in Vaxart, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
