Blaize (BZAI) CRO Stephen Patak Receives 2,500 Shares (RSU Vesting)

What Happened

  • Stephen Paul Patak, Chief Revenue Officer of Blaize Holdings, had 2,500 restricted stock units (RSUs) convert into common shares on July 12, 2026. The reported exercise/conversion price was $0.00 (no cash exercise).
  • To cover tax withholding, 609 shares were surrendered at $1.23 per share for a withholding value of $749. After withholding, Patak received a net 1,891 shares (2,500 vested − 609 withheld).
  • This was a vesting/award event (not an open-market purchase or sale).

Key Details

  • Transaction date: July 12, 2026; filing date: July 13, 2026 (timely).
  • Conversion/exercise code: M (exercise/conversion of derivative); tax withholding code: F.
  • Withholding: 609 shares at $1.23 = $749.
  • Net shares delivered to insider: 1,891 (based on the reported vesting and withholding).
  • Footnotes: F1–F3 confirm these were vested restricted stock units (each RSU = one share) and that these RSUs vest in quarterly installments beginning April 12, 2026. F4 notes separate stock options vest 25% on Jan 12, 2027 and quarterly thereafter.
  • Shares owned after the transaction were not specified in the provided summary of the filing.

Context

  • This was a routine vesting and tax-withholding event (award received), not an open-market sale or purchase; withholding of shares to cover taxes is common and does not necessarily indicate a change in insider sentiment.
  • The Form 4 shows both the RSU/derivative conversion (M) and the F withholding entry; in plain terms, RSUs converted to shares and a portion was withheld to satisfy tax obligations.
