GRANT OF SHARE PLAN AWARDS
Costain announces the following grants of share awards to Alex Vaughan, Chief Executive Officer, and Helen Willis, Chief Financial Officer.
SHARE DEFERRAL PLAN AWARDS
On 10 April 2026, awards have been made under The Costain 2023 Share Deferral Plan (Share Deferral Plan) over ordinary shares of 1p each in the Company in the form of options with a nil exercise price (SDP Awards). An SDP Award was granted to Alex Vaughan over 118,103 shares and Helen Willis over 97,615 shares, each representing deferral into shares of one third of their 2025 Annual Incentive Plan earned. No consideration was paid for the grant of the Awards.
The SDP Awards will normally become exercisable on the second anniversary of the grant date subject to the rules of the Share Deferral Plan. To the extent that all or any part of the SDP Awards become exercisable, they will remain exercisable until the tenth anniversary of the date of grant provided the individual remains an employee or officer of the Company.
The Notification of Dealing Forms for both directors, set out below, are provided in accordance with the requirements of the UK Market Abuse Regulation.
