Rhea-AI Filing Summary

Viant Technology Inc. CEO and Chairman Timothy Vanderhook reported a series of estate-planning transactions involving Class B Common Stock and Class B Units tied to Class A common stock.

grantor retained annuity trust financial
"Securities held by the Eve Vanderhook 2024 grantor retained annuity trust."
A grantor retained annuity trust (GRAT) is an estate-planning tool where the person who creates the trust transfers assets into it but receives fixed cash payments (an annuity) from the trust for a set number of years; whatever remains after that term passes to designated beneficiaries. It matters to investors because it can shift future appreciation of assets out of the creator’s taxable estate—like putting an asset into a timed vending machine that pays you fixed amounts while any extra value that grows inside the machine goes to heirs with reduced gift or estate tax consequences.
Class B Units financial
"The Class B Units of Viant Technology LLC ("Class B Units") are exchangeable..."
Class A common stock financial
"exchangeable, at the holder's option, on a one-for-one basis into shares of Class A common stock of the Issuer."
Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.
pecuniary interest financial
"may therefore be deemed to have an indirect pecuniary interest in one-third of Capital V LLC's total holdings."
Rule 16a-13 regulatory
"annuity payments by the GRATs to the Reporting Person... were exempt from reporting pursuant to Rule 16a-13."
