Forward-Looking Statements

In connection with the provisions of the Private Securities Litigation Reform Act of 1995 (the “Reform Act”), WPP plc and its subsidiaries (the “Company”) may include forward-looking statements (as defined in the Reform Act) in oral or written public statements issued by or on behalf of the Company. These forward-looking statements may include, among other things, plans, objectives, projections and anticipated future economic performance based on assumptions and the like that are subject to risks and uncertainties. As such, actual results or outcomes may differ materially from those discussed in the forward-looking statements. Important factors that may cause actual results to differ include but are not limited to: the unanticipated loss of a material client or key personnel, delays or reductions in client advertising budgets, shifts in industry rates of compensation, regulatory compliance costs or litigation, natural disasters or acts of terrorism, the Company’s exposure to changes in the values of major currencies other than the UK pound sterling (because a substantial portion of its revenues are derived and costs incurred outside of the United Kingdom) and the overall level of economic activity in the Company’s major markets (which varies depending on, among other things, regional, national and international political and economic conditions and government regulations in the world’s advertising markets). In addition, you should consider the risks described in Item 3D, captioned “Risk Factors” in the Company’s Form 20-F for the year ended 31 December 2019, which could also cause actual results to differ from forward-looking information. In light of these and other uncertainties, the forward-looking statements included in the oral or written public statements should not be regarded as a representation by the Company that the Company’s plans and objectives will be achieved.

The Company undertakes no obligation to update or revise any such forward-looking statements, whether as a result of new information, future events or otherwise.
