Viant Technology Inc. (NASDAQ: DSP) saw its stock price surge 5.95% in after-hours trading on Monday 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 adjusted earnings of $0.12 per share, handily beating the analyst consensus estimate of $0.07 by 71.43%. Revenue for the quarter reached $85.582 million, slightly above the expected $85.517 million, representing a 7.08% increase compared to the same period last year. Notably, Viant's adjusted net income soared to $11.205 million, vastly outperforming the estimated $1.52 million.

Viant's strong performance was primarily attributed to record CTV ad spend, which accounted for 46% of total ad spend during the quarter. This growth in CTV, coupled with new brand partnerships, including a multi-year agreement with Molson Coors for programmatic advertising campaigns, contributed to the company's robust results. Additionally, Viant provided an optimistic outlook for Q4 2025, projecting revenue between $101.5 million and $104.5 million, with an adjusted EBITDA margin of 37%. The company's success in navigating the evolving digital advertising landscape and its strategic focus on high-growth areas like CTV appear to be resonating well with investors, as reflected in the stock's after-hours rally.
