The Omnicom–IPG Merger: Why the acquired company always pays the higher price

The news of the Omnicom–IPG merger has triggered a wave of speculation across the global advertising industry. But beneath the financial engineering, the shareholder excitement, and the “synergy” decks is a truth anyone who has lived through a merger already knows: the acquired company always bears the deeper scars.

In this case, Omnicom is the buyer. IPG is the acquired. And that automatically sets the direction of cultural impact, structural consolidation, and unfortunately, the human cost.

Advertising has seen this movie before. When WPP began collapsing its agency networks into singular holding identities, we watched legendary brands disappear almost overnight. We lost JWT, the world’s oldest advertising agency. Y&R, once the benchmark of Madison Avenue influence. Bates, a pioneer of global expansion. And even Grey, a network that produced some of the most iconic global campaigns and cultivated decades of creative heritage. Names that shaped the craft, nurtured generations of creative talent, and built some of the world’s most iconic campaigns simply vanished because the spreadsheets said so.

The Omnicom–IPG merger will likely follow a similar script.

Brand rationalisation will be the first domino to fall. Two holding companies don’t need two of everything :two creative networks, two media networks, two healthcare groups, two PR powerhouses. And history tells us which brands survive: the buyer’s. That means several well-known IPG agencies may be wound down or folded into Omnicom structures. Iconic brands that advertisers and talent grew up with may not exist a year from now.

Job losses will follow. Not because people aren’t adding value, but because consolidation always demands “efficiency.” Duplicate roles are the first targets :finance, HR, strategy, creative redundancies, regional leadership layers. Thousands of people who built IPG’s legacy will suddenly find themselves on the wrong side of a merger they didn’t choose.

And then there is the cultural displacement, the part no press release ever acknowledges. The acquired company’s ways of working, decision frameworks, and leadership philosophies gradually get overwritten. It’s never malicious; it’s structural. The acquirer’s templates, processes, and priorities naturally become the default operating system.

The tragedy is that advertising isn’t a widget business. It’s a business built on identity, culture, and the magic of teams. When you erase brands, you erase legacies. When you flatten structures, you flatten the very diversity of thought that made this industry vibrant.

It’s easy to herald mergers as “the future of integrated, scaled creativity.” But for those who have witnessed the dismantling of great agencies in earlier consolidations, this moment feels less like evolution and more like déjà vu.

We will adapt. The industry will reinvent itself. New players will rise. But let’s not pretend nothing was lost along the way.

Because every time a merger happens, it is the acquired company that loses more :its brands, its people, and often, its voice.

And this time, that company is IPG.
