Terry Roberts, Executive Chair of WhiteHawk, commented,

“The separation of the Chair and CEO role will enable me to focus more on the growth of the US business and is in keeping with corporate governance best practice for ASX listed companies. The new Chair will be fully independent such that the Board will then consist of a majority of independent Directors which also meets corporate governance best practice on ASX.

“In addition, having established the WHK APEC Office in November 2025, it is time to take our Regional growth to the next level under a new Australian based and regionally focused CEO. This is all about advancing the impact of our Cyber Risk Solutions at scale across the Asia Pacific sector and having a CEO based in Australia who can grow both business and investor interest in the Company.”
