Why did WPP leave the FTSE 100?

Its share price decline dropped its market capitalization below the index threshold, and it was demoted from the FTSE 100 in December 2024 after 26 years in the index.

The corporate shell dates to 1971 as Wire and Plastic Products plc, a UK manufacturer of wire shopping baskets. Martin Sorrell bought a stake in 1985 and took control, using the listed shell as the vehicle for the most aggressive acquisition spree in advertising history.

Sorrell's insight was that advertising agencies were undervalued assets that could be assembled into a global services group. He bought small agencies first, then moved on to the industry's landmark takeovers: J. Walter Thompson in 1987 for $566 million and Ogilvy in 1989 for $864 million, both hostile, both transformative.

Through the 1990s and 2000s WPP absorbed the famous names of advertising: Young & Rubicam, Grey, Bates, Hill & Knowlton, Burson-Marsteller, and media networks that became GroupM. Sorrell built it into the world's largest communications group by 2013.

The 2016 merger attempt with Publicis collapsed at the altar, leaving the two groups as permanent rivals for the global crown. Sorrell's own 2018 exit after a personal conduct investigation ended his 33-year run and passed the group to Mark Read.

Read simplified the structure through mergers: Wunderman Thompson combined Wunderman and JWT in 2018, VMLY&R joined VML and Y&R in 2018, BCW merged Burson-Marsteller and Cohn & Wolfe in 2018, and the 2023 VML merger combined VMLY&R and Wunderman Thompson into one network.

The recent years have been the group's hardest. WPP lost its revenue crown to Publicis, dropped from the FTSE 100 in December 2024, and reported 2025 revenue of 13.6 billion pounds, down 8.1 percent on a like-for-like basis excluding currency and acquisitions. Cindy Rose replaced Mark Read as CEO in September 2025, inheriting a restructuring aimed at AI-driven services and simplified operations.

WPP's ethics questions are the advertising industry's own: its work for fossil fuel clients has drawn sustained criticism from climate campaigners and internal staff, putting it at the center of the debate over agencies' role in promoting carbon-intensive products.

The group publishes sustainability reporting covering its own footprint and the contested territory of client work ethics, including commitments to net zero in operations while facing pressure over high-carbon client relationships.

As an employer of nearly 100,000 people, it also reports on diversity, labor practices, and the mental health pressures of agency work that industry surveys document.

Martin Sorrell's 2018 exit after a personal conduct investigation was the group's defining governance scandal, ending the founder era amid boardroom acrimony and press coverage of the circumstances.

The fossil fuel client work has generated sustained activist pressure, including shareholder resolutions and staff petitions calling on the group to drop oil and gas clients, a debate it continues to navigate.

Recent financial decline has drawn its own scrutiny: the FTSE 100 demotion, revenue losses, and executive turnover are covered as evidence of the traditional agency model's structural problems.
