Analysis · WPP · Trade & Services
WPP's CFO is leaving for the same role at Diageo, a major FTSE 100 peer. The departure comes as WPP is mid-way through its Elevate28 restructuring, with H1 2026 revenue down 4.4% and the company trying to return to growth. A 12-month notice period gives WPP time for an orderly handover, but losing the CFO during a transformation adds execution risk. The company reaffirmed its 2026 guidance, which limits near-term uncertainty.
