Advertising company WPP PLC is set to exit London's premier FTSE 100 index after more than 27 years, according to a quarterly review from FTSE Russell.

WPP will be replaced by British Land Co., with the change to be implemented at the close of business on Dec. 19 and effective from the start of trading on Dec. 22.

The FTSE 100 is a share index of the 100 most highly-capitalized companies listed on the London Stock Exchange. Any company that falls to 111th and below is automatically ejected from the top-flight index, while any that rises to 90 or above is automatically promoted.

WPP--which owns agencies such as Ogilvy and VML--cut its guidance for the second time in October, and its new Chief Executive Officer Cindy Rose said she expected the company's turnaround to take time. WPP stock is down 65% year-to-date.

Shares of British Land, which owns retail sites and office-led campuses in Central London and throughout the U.K., have risen nearly 17% over the year to date. It recently reported improved earnings for the first half of the year on the back of strong occupancy rates and leasing activity.

British Land was last in the index between October 2024 and March of this year. WPP has been in the index since June 1998.
