Viant Technology Inc. (NASDAQ: DSP) saw its stock price surge 6.06% in after-hours trading following the release of its impressive third-quarter 2025 financial results. The advertising technology company significantly outperformed analyst expectations, driven by robust growth in Connected TV (CTV) advertising and strategic partnerships.

The company reported quarterly earnings of $0.12 per share, beating the analyst consensus estimate of $0.07 by 64.38%. Although this represents a 20% decrease from the same period last year, Viant's financial performance exceeded market expectations. Revenue for the quarter came in at $85.582 million, slightly above the analyst estimate of $85.517 million, marking a 7.08% increase year-over-year.

Viant's strong performance was largely attributed to its success in the CTV advertising space. The company reported record CTV ad spend, accounting for 46% of total ad spend during the quarter. This growth was further bolstered by new partnerships, including a multi-year agreement with Molson Coors for programmatic advertising campaigns. Additionally, the adoption of Viant's Household ID and IRIS_ID addressability solutions contributed to the revenue growth. Looking ahead, Viant provided an optimistic outlook for the fourth quarter, projecting revenue between $101.5 million and $104.5 million, with an adjusted EBITDA margin of 37%.
