(1) Represents shares of Class B common stock, par value $0.001 per share ("Class B common stock"), of
Viant Technology Inc. (the "Issuer") held directly by Mr. Vanderhook.

(2) Does not account for shares of Class B common stock held directly by Four Brothers 2 LLC ("Four
Brothers"). Mr. Vanderhook also holds a one-third interest in Four Brothers, representing an economic interest in an additional 9,483,701 shares of Class B common stock and 9,483,701 Class B Common Units of Viant
Technology LLC ("Class B Units"). Voting and investment decisions by Four Brothers require approval of a majority-in-interest of the members of Four Brothers, and accordingly no individual has voting or investment control
over the shares held by Four Brothers.

(3) Pursuant to the Second Amended and Restated Limited Liability Company Agreement of Viant Technology LLC, dated
as of February 9, 2021 (the "Viant Technology LLC Agreement") and an exchange policy adopted by Viant Technology LLC, holders of Class B common stock may surrender Class B Units, along with an equivalent number of shares
of Class B common stock, to the Issuer (the Managing Member of Viant Technology LLC) or Viant Technology LLC in exchange for an equivalent number of shares of the Issuer's Class A common stock, par value $0.001 per share
("Class A common stock") or, at the Issuer's election, for cash. Each share of Class A common stock and Class B common stock is entitled to one vote.

(4) Percent of Class A common stock is calculated based on a denominator of 22,477,542, consisting of (i)
14,643,798 shares of Class A common stock outstanding as of December 31, 2022 and (ii) an additional 7,833,744 shares of Class A common stock, which assumes the surrender of all shares of Class B common stock and
Class B Units held by Mr. Vanderhook as of December 31, 2022 for an equivalent number of shares of Class A common stock pursuant to the Viant Technology LLC Agreement and Viant Technology LLC's exchange policy, and deemed as
outstanding Class A common stock for purposes of computing this percentage in accordance with Rule 13d-3(d) of the Securities Exchange Act of 1934, as amended.

(5) Percent of outstanding common stock and voting power is calculated based on a denominator of 61,726,058,
consisting of (i) 14,643,798 shares of Class A common stock and (ii) 47,082,260 shares of Class B common stock, in each case outstanding as of December 31, 2022.
