Following 13 years on the Board, Ann Budge has informed the Board that she will be retiring as a Non-executive Director with effect from 28 February 2023. Ann was an early-stage investor in Calnex and was pivotal in bringing the Discovery Investment Fund syndicate as investors when the Group raised seed investment in 2007. Since this time, Ann has made a significant contribution to Calnex, in particular by supporting Tommy Cook, CEO and Founder, as he sought to establish Calnex as a leader in the test and measurement sector.

Stephen Davidson, Non-Executive Chairman of Calnex, commented:

"We are excited to welcome Helen to the Board. Her experience across the cloud and data centre world will undoubtedly be of immense value to Calnex as we exploit the growth in the testing market, with the need for greater efficiency and performance in data centre operations.
