Viant (DSP) COO Christopher Vanderhook Sells 8,636 Shares

What Happened

• Christopher Vanderhook, Chief Operating Officer of Viant Technology Inc. (DSP), had 8,636 shares disposed of to the issuer on September 10, 2026 at $12.74 per share, for a total of $110,023. This disposition was an issuer repurchase to cover estimated taxes tied to the vesting of restricted stock units (RSUs), not an open-market sale.

Key Details

• Transaction date and price: September 10, 2026 — 8,636 shares at $12.74 each (total $110,023).
• Nature of transaction: Disposition to issuer (repurchase for tax withholding tied to RSU vesting), not a market sale.
• Vesting context: The repurchase covered estimated taxes on 16,198 RSUs that vested on September 10, 2026; 8,636 shares were withheld, implying roughly 7,562 net vested shares delivered to the reporting person.
• Footnote: “Repurchased by the Issuer … in the amount of estimated taxes to be paid … in connection with the vesting of 16,198 restricted stock units on September 10, 2026.”
• Filing date and timeliness: Form 4 filed September 14, 2026; given the Sept. 10 transaction, this filing appears to be within the standard two business-day window and therefore timely.

Context

• This was a routine tax-withholding action commonly used when RSUs vest (a “sell to cover” or issuer repurchase). Such transactions are administrative and do not necessarily indicate the insider’s view of the company’s stock.
• For retail investors, direct open-market purchases by insiders tend to be more informative about sentiment than withholding sales tied to compensation events.
