Introduction

WPP’s EPSP was approved by shareowners in June 2013 and today’s announcement is the first five-year outcome under the EPSP. The arithmetic application of the EPSP metrics has resulted in a vesting of 72.8% of the maximum.

The outcome results in the vesting of 858,730 shares for Sir Martin Sorrell, CEO, which were valued at £10.0m at the vesting price of £11.655435 per share on 13 March 2018.

This covers a five-year performance period in which the FTSE 100 rose 30.3% while WPP’s shares rose 51.0%. £1,000 invested in WPP at the start of the period increased to £1,510 by the end of 2017 compared with £1,303 if invested in the FTSE 100. WPP’s market capitalisation increased by 51.6% to £17.03 billion ($23.0 billion). The decline in WPP’s share price since the end of the 2013-17 performance period has been reflected in the value received by executives in the current awards vesting and will be in future cycles of the EPSP.
