WPP Plc is targeting £500 million ($678 million) in annual cost savings by 2028 as part of a sweeping restructuring that the embattled British advertising group hopes will help it to return to growth next year. The announcement signals a major strategic shift for the advertising conglomerate, which has faced significant challenges in recent years. This ambitious savings target represents a substantial portion of its current operational budget and underscores the scale of the cost-cutting drive required to stabilize the company.
