Vanderhook Christopher 4

What Happened

• Christopher Vanderhook, Chief Operating Officer of Viant Technology (DSP), sold a total of 12,500 shares of Class A common stock in open‑market transactions executed Jan 20–22, 2026, receiving about $153,130 in aggregate (5,000 @ $11.94 = $59,702; 4,926 @ $12.24 = $60,297; 2,574 @ $12.87 = $33,131).
• The filing also reports conversion/exchange-type derivative activity (12,500 shares acquired via exercise/conversion at $0 and related cancellations/dispositions to the issuer). Footnotes explain these involve exchangeable Class B Units being converted into Class A shares and certain Class B common stock being cancelled for no consideration.
• These open‑market sales were made as the reporting person’s pro rata portion of share sales by Capital V LLC and were effected pursuant to a 10b5‑1 plan.

Key Details

• Transaction dates and prices: Jan 20, 2026 — 5,000 shares at $11.94; Jan 21, 2026 — 4,926 shares at $12.24; Jan 22, 2026 — 2,574 shares at $12.87. Reported totals: ~$153,130.
• Some reported prices are weighted averages of larger blocks sold on behalf of Capital V LLC; disclosed price ranges for those blocks span approximately $11.615–$13.195 (see footnotes F5–F7). The filer can provide per‑trade breakdowns upon request.
• Sales were made pursuant to a 10b5‑1 plan adopted by Capital V LLC (originally March 18, 2025; amended Sept 17, 2025) (F4). The reporting person holds a one‑third interest in Capital V LLC and therefore has an indirect pecuniary interest in one‑third of those holdings (F2).
• Derivative detail: Class B Units are exchangeable one‑for‑one into Class A shares; upon exchange the related Class B common stock is cancelled (F1, F3). The $0 exercise/conversion reflects this exchange/cancellation process, not a cash purchase price.
• Shares owned after the transactions are not specified in the provided excerpt. The Form 4 was filed Jan 22, 2026 reporting trades through Jan 22, 2026.

Context

• These filings show sales (not purchases). The use of a 10b5‑1 plan and the fact that some sales were made via Capital V LLC indicate the trades were part of prearranged dispositions rather than one‑off open‑market timing by the insider. Derivative entries reflect conversion/exchange of Class B Units into Class A shares and related cancellations, not a cash exercise payment.
