The Weir Group PLC (the "Company" or the "Weir Group") announces that the Board of Directors of the Company (the "Board") has established a new Sustainability and Technology Committee.

The Sustainability and Technology Committee will be chaired by independent non-executive director Tracey Kerr, who will be joined by Dame Nicola Brewer, Penny Freer and Ben Magara. The Sustainability and Technology Committee will provide both strategic and governance oversight to explore the future of the mining industry and the implications for the Weir Group's fully integrated business model.

The Company also announces that, having served on the Board for nine years, non-executive director Sir Jim McDonald will be stepping down with effect from the conclusion of the Company's annual general meeting, which is due to be held on 25 April 2024. Dame Nicola Brewer will succeed Sir Jim as Senior Independent Director, and Ben Magara will succeed Dame Nicola as designated non-executive director for employee engagement with effect from the same date.

Commenting, Barbara Jeremiah, Chair of the Weir Group said:

"Sustainability and technology are both core to Weir's purpose to enable the sustainable and efficient delivery of the natural resources essential to create a better future for the world. The Board and I are delighted to dedicate additional time and resources to these strategic priorities through the establishment of the Sustainability and Technology Committee.

I would also like to thank Sir Jim for his many years of dedication to the Weir Group and the work of the Board since he joined us in 2015. Sir Jim's contribution to the Board during his tenure, including in his position of Senior Independent Director, has been both insightful and invaluable. On behalf of the Company and the Board, we wish Sir Jim all the best for the future and are delighted to see Dame Nicola succeed him in this role."

In light of the changes described above, the Board also has reviewed the membership of its existing Committees. With immediate effect, the membership of the Committees of the Board is as follows:
