Omnicom Group's stock soared 6.31% during intraday trading on Thursday, following the release of its fourth-quarter 2025 financial results.

The advertising giant reported quarterly revenue of $5.53 billion, a significant 27.9% increase year-over-year that surpassed analyst expectations. This strong top-line growth was driven primarily by the company's recent acquisition of Interpublic Group.

Investors also responded positively to the announcement of a new $5 billion share repurchase program, which includes $2.5 billion in accelerated share repurchases. This substantial capital return initiative signals management's confidence in the company's financial strength and future prospects.
