Vaxart (VXRT) CFO Jeroen Grasman Receives Equity Awards

What Happened

Jeroen N. Grasman, Chief Financial Officer of Vaxart, Inc. (VXRT), received two equity awards on 2026-03-16: 227,000 restricted stock units (RSUs) and a 455,000-share derivative award (stock option). Both were reported as acquired at $0.00 per share on the Form 4 filing.
These were grants/awards (compensation), not open-market purchases or sales. No cash changed hands at grant.

Key Details

Transaction date: March 16, 2026; Form 4 filed March 18, 2026 (filed two days after the transaction).
Reported prices: $0.00 for both the RSU award and the derivative award (standard for grants).
Shares owned after transaction: not specified in the filing.
Footnotes:
- F1 (RSUs): 25% of the 227,000 RSUs vest on each anniversary starting March 16, 2026; fully vested after four years.
- F2 (Option): 25% of the 455,000-share option vests on March 16, 2027, then vests in 36 equal monthly installments, fully vested March 16, 2030.
No indication of a 10b5-1 plan, tax-withholding sale, or immediate cashless exercise in the filing.

Context

These grants appear to be standard compensation awards rather than purchases — common when companies grant RSUs and options to executives. RSUs deliver actual shares as they vest; the derivative award is a stock option subject to multi-year vesting.
Because no shares were sold or bought in the open market and the awards vest over time, this filing alone shouldn’t be read as a near-term trading signal.
