KISZKA ROBERT 4

What Happened

• Robert Kiszka, Executive Vice President of Operations at Smart Sand (SND), had 2,591 shares withheld on 2026-03-17 to cover tax obligations triggered by the vesting of restricted stock. The shares were valued at $4.08 each for a total of $10,571. This is a tax-withholding disposition (code F), not an open-market sale.

Key Details

• Shares withheld/disposed: 2,591 at $4.08 per share; total value ~$10,571.
• Shares owned after the transaction: not specified in the provided filing excerpt.
• Footnotes of note:
  • F1: Withholding was done to satisfy tax liabilities upon vesting of restricted stock tied to continued service.
  • F2: Some holdings are held by an LLC of which Kiszka is the sole member; he disclaims beneficial ownership of LLC assets except to the extent of his pecuniary interest.
• Transaction code: F (tax withholding on vesting).

Context

• This action is a routine tax-withholding event tied to equity vesting and does not necessarily signal a personal decision to sell shares on the open market. For investors, purchases or open-market sales by insiders can be more informative about sentiment than withholding transactions like this one.
