SIG plc

("SIG" or the "Company")

Publication of Circular convening a General Meeting

LEI: 213800VDC1BKJEZ8PV53

The Company has today published a circular convening a General Meeting seeking shareholder approval for certain changes to incentive arrangements for the Executive Directors and other Key Executives of the Company (the "Circular").

As noted in the Remuneration Committee Report contained in the Company's Annual Report and Accounts for the financial year ended 31 December 2017 (the "Annual Report"), at the time of publication of the Annual Report, the Remuneration Committee was conducting a review of the incentive arrangements for the Executive Directors and other Key Executives of the Company and was consulting extensively with the Company's main shareholders and the main shareholder representative bodies in order to agree the appropriate remuneration approach to support the strategy of the Company. This dialogue was ongoing at the time of the 2018 Annual General Meeting and therefore it was inappropriate to bring a new Remuneration Policy and incentive plans to a shareholder vote at this meeting. The Remuneration Committee has now completed its consultation exercise and is keen to ensure that the new remuneration strategy is in place as soon as possible to support the business strategy given that no Long Term Incentive Plan ("LTIP") award has been made this year.

The Circular contains further details on the background to, and the reasons for, the proposals. The Circular also contains a notice convening a General Meeting of the Company to be held at the offices of Herbert Smith Freehills LLP at Exchange House, Primrose Street, London EC2A 2EG at 12 noon on Wednesday 7 November 2018. A summary of the resolutions to be proposed at the General Meeting is set out below.

Resolution 1 - Approval of Directors' Remuneration Policy (ordinary resolution)

Resolution 1 seeks approval of the Company's future Directors' Remuneration Policy which if approved will take effect from the conclusion of the General Meeting.

Resolution 2 - Approval of the SIG plc Bonus Plan (ordinary resolution)

Resolution 2 seeks approval of the SIG plc Bonus Plan.

Resolution 3 - Approval of the SIG plc 2018 Long Term Incentive Plan (ordinary resolution)

Resolution 3 seeks approval of the SIG plc 2018 Long Term Incentive Plan.
