FORTERRA PLC

AGM RESOLUTION 13 - APPROVAL OF REMUNERATION POLICY

At the forthcoming Annual General Meeting ("AGM") of Forterra plc (the "Company") on 19 May 2026, shareholders will be asked to vote on a number of resolutions, including Resolution 13 relating to the approval of the Remuneration Policy (the "Policy").

In advance of the AGM, the Remuneration Committee wishes to provide further clarification in relation to Resolution 13.

The Policy proposes a hybrid long-term incentive structure for Executive Directors, comprising 50% performance shares and 50% restricted shares. No change is proposed to the current Policy maximum notional performance share award level of 200% of salary (250% in exceptional circumstances). For 2026, award levels will be 175% of base salary for the Chief Executive Officer and 150% of base salary for the Chief Financial Officer, on a notional performance share basis, with a 50% discount applied to the restricted share element.

If approved, the performance share element will be subject to the following measures over the period ending 31 December 2028:

Vesting will be calculated on a straight-line basis between the relevant performance points.

The notional share award level for both performance shares and restricted shares will be based on the average closing share price of the Company's shares over the six-month period ended 19 May 2026. The Remuneration Committee believes this provides a balanced basis for calculating awards by reducing the impact of short-term market volatility and external macroeconomic uncertainty on the number of shares granted.

The Board looks forward to the support of shareholders in approving Resolution 13 at the AGM on 19 May 2026.
