Grant under Performance Share Plan

Forterra plc (the "Company") announces that on 17 March 2022 awards over ordinary shares of £0.01 each in the capital of the Company were granted to certain Directors and persons discharging managerial responsibility ("PDMRs") under the Forterra plc Performance Share Plan ("PSP") as follows:

No consideration was paid for the grant of the awards which are structured as nominal cost options at an option exercise price of £0.01 per Ordinary Share. The number of Ordinary Shares granted under the award has been calculated using a share price of £2.31 being an average mid-market quotation as derived from the London Stock Exchange Daily Official List for the last 5 days of trading.

The vesting of an award is subject to the satisfaction of performance conditions which have been set by the Remuneration Committee of the Board of Directors of the Company. Half of the awards are subject to TSR and EPS performance measures respectively. The awards will normally vest on 17 March 2025, subject to the achievement of the performance conditions and the participant being a director or employee within the Company's group at that time.

Further information regarding the PSP is set out in the Annual Report and Accounts.

The above notification is intended to satisfy the Company's obligations under Article 19 of the Market Abuse Regulations.
