Management Comments

• Tim Vanderhook, Co-Founder and CEO: "Viant delivered record third quarter results, with revenue, contribution ex-TAC and adjusted EBITDA all exceeding the midpoint of our guidance. We believe we are well-positioned to accelerate top-line growth, fueled by strengthening CTV demand, broader adoption of our proprietary addressability solutions, Household ID and IRIS_ID, and new brand partnerships enabled by ViantAI. We are thrilled to partner with a number of major brand advertisers, including Molson Coors Beverage Company, who collectively share our vision of achieving outcomes through autonomous advertising, powered exclusively by ViantAI."
• Larry Madden, CFO: "We are pleased to deliver third-quarter results that exceeded expectations. Contribution ex-TAC grew 12%, reaching the high-end of our guidance range. When excluding political spend and the impact of a seasonal advertiser transitioning off platform due to a recent corporate merger, revenue increased 19% and contribution ex-TAC increased 22%, reflecting strong underlying business performance. Our disciplined expense management also enabled us to increase adjusted EBITDA by nearly 10% in the quarter. Looking ahead to the fourth quarter, excluding these same headwinds, we expect revenue and contribution ex-TAC growth of 20% and 21%, respectively, at the midpoint of our guidance, underscoring continued momentum in our business. In addition, we expect to achieve an adjusted EBITDA margin of 37% as a percentage of contribution ex-TAC at the midpoint of our guidance, representing more than 500 basis points of improvement over the prior year period at the midpoint. We believe we are poised to meaningfully accelerate both top and bottom-line growth, attributable to a number of newly acquired brand and agency clients seeking to utilize our unique CTV product offering, industry-leading addressability solutions and ViantAI product suite."
