Rio Tinto has made changes its board after the size of its board peaked at 14 directors during a transitional period.
Simon Henry and Martina Merz recently stepped down as directors.
Henry has served on the board since April 2017 and has completed the handover to Sharon Thorne, who has succeeded him as chair of the audit and risk committee.
Meanwhile, Merz decided to step down to dedicate more time to building innovation ecosystems.
Ben Wyatt has been appointed as senior independent director, while Susan Lloyd-Hurwitz joined the sustainability committee of the board, to replace Martina Merz.
Lloyd-Hurwitz will continue in her existing role as designated non-executive director for workforce engagement.
The changes took effect on 23 October.
Sam Laidlaw and Kaisa Hietala stepped down from the board at the conclusion of the company’s 2025 annual general meetings, in May.
