Viant Technology Inc. (NASDAQ: DSP) saw its stock price surge 6.06% in after-hours trading on Monday following the release of its impressive third-quarter 2025 financial results. The company, which specializes in programmatic advertising technology, reported earnings that significantly exceeded analyst expectations.

Viant's Q3 adjusted earnings per share came in at $0.12, handily beating the analyst consensus estimate of $0.07 by 71.43%. The company's 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.

The strong performance was primarily driven by record connected TV (CTV) ad spend, which accounted for 46% of total ad spend. This growth in CTV, coupled with new brand partnerships and increased adoption of Viant's addressability solutions, 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, further boosting investor confidence. 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 the market, as reflected in the stock's after-hours rally.
