[6][7] In November 2018, it was announced that Geoff Drabble would retire as CEO after twelve years on 1 May 2019, and would be succeeded by Brendan Horgan, the Group Chief Operations Officer and chief executive of Sunbelt Rentals, Ashtead's North American business.

[8] In June 2022, Sunbelt Rentals, Ashtead's main operating subsidiary, was announced as an investor in lithium-ion battery developer Britishvolt.

[10] In December 2024, Ashtead announced plans (to be discussed with shareholders) to move its primary stock market listing from London to the US.

It said the US was a "natural long term listing venue" because most of the group's profit came from North America, and its leadership, most of its 25,000 employees and its headquarters were all in the US.

[12] The company's non-executive directors are Paul Walker, Angus Cockburn, Jill Easterbrook, Tanya Fratto, Reneta Ribeiro, Lucinda Riches and Lindsley Ruth.
