Vanderhook Christopher 4

What Happened

• Christopher Vanderhook, COO of Viant Technology Inc. (DSP), reported conversions/exercises of derivative units and multiple open‑market sales. On 2026-02-17 he converted/exercised 12,500 Class B Units into Class A common stock (no cash consideration reported) and a related cancellation/redemption occurred. Separately, Vanderhook (pro rata through Capital V LLC) sold a total of 12,080 Class A shares in open‑market transactions: 4,079 shares at $9.26 (≈ $37,790) on 2026-02-17; 4,722 shares at $9.19 (≈ $43,373) on 2026-02-18; and 3,279 shares at $9.17 (≈ $30,074) on 2026-02-19 — total proceeds ≈ $111,237. The filing also reports a derivative-related disposition tied to the conversion/redemption process.

Key Details

• Transaction dates and prices: 2/17/2026 (conversion of 12,500 units; open‑market sale 4,079 @ $9.26), 2/18/2026 (sale 4,722 @ $9.19), 2/19/2026 (sale 3,279 @ $9.17).
• Total open‑market proceeds reported ≈ $111,237.
• The conversions involve Class B Units that are exchangeable one‑for‑one into Class A shares; certain Class B common stock shares were cancelled for no consideration in connection with a redemption by Capital V LLC (footnotes F1, F3).
• Several sales were effected pro rata on behalf of Capital V LLC under a 10b5‑1 plan adopted March 18, 2025 (amended Sept 17, 2025); Vanderhook holds a one‑third interest in Capital V LLC and may be deemed to have an indirect pecuniary interest in one‑third of its holdings (F2, F4).
• Reported prices include weighted averages based on larger block sales by Capital V LLC, with price ranges across tranches of $9.02–$9.56 (F5–F7); Vanderhook offers to provide breakdowns on request.
• Shares owned after the transactions were not specified in the provided data. The Form 4 was filed on 2026-02-19 for transactions beginning 2026-02-17 (filed within the typical Form 4 reporting window; not indicated as late).

Context

• The filing shows both a conversion/exchange of derivative units and routine open‑market sales (some made pursuant to a 10b5‑1 plan). The conversions/cancellations involved no cash proceeds; the cash received reflects only the open‑market sales. These are factual disclosures of insider activity and do not, by themselves, indicate the Reporting Person’s motivations.
