Key Details
- Transaction date: 2026-06-09; Form 4 filed 2026-06-10 (timely filing).
- Transaction types: eight Gifts (G) and eight Grants/Awards (A); eight of the entries are marked as derivative transactions.
- Shares per entry: 52,096; total shares transacted: 833,536; reported dollar value: $0.
- Holdings after transaction: not specified in the provided excerpt of the filing.
- Notable footnotes:
- F1: GRAT annuity payments to the reporting person were made and are exempt from reporting under Rule 16a-13.
- F2–F5: Securities are held by four separate grantor retained annuity trusts (Hayden, Carter, Clay, Colbie Vanderhook 2024 GRATs).
- F6: Reporting person holds a one-third interest in Capital V LLC and may have an indirect pecuniary interest in one-third of its holdings.
- F7: Class B units of Viant Technology LLC are exchangeable one-for-one into Class A common stock (derivative exchangeability).
- No indication in the filing that these were open-market sales or purchases; gifts and awards do not necessarily signal market sentiment.
Context
- Gifts generally reflect estate-planning or family transfers and are not direct indicators of insider bullish/bearish views. Grants/awards may reflect internal equity plan actions or reclassifications, especially when reported at $0 and tied to trusts.
- Several entries are labeled as derivative transactions; per the filing, those may involve exchangeable Class B units (one-for-one exchange into Class A shares), so some items reflect derivative interests rather than direct open-market activity.
- The filing appears timely (filed one day after the transaction date), and the footnotes clarify trust holdings and annuity treatment rather than trading under a 10b5-1 plan.
