Omnicom Group Inc. has agreed to acquire Interpublic Group of Companies Inc. in a stock-for-stock transaction, creating the world's largest advertising company. The deal, which has been confirmed by both companies, is expected to close in the second half of 2025. The merger will combine two Madison Avenue giants, reshaping the advertising industry as it faces pressures from digital transformation and the dominance of tech companies in ad revenues. The transaction values Interpublic between $13 billion and $14 billion, excluding debt, according to sources cited by the Wall Street Journal. This move comes at a time when the global advertising industry is projected to hit $1 trillion in revenue for the first time in 2024, with digital advertising accounting for 73% of the total.
