On November 3, 2022, AGL Energy announced that it is facing the escalating threat of another clash with investors as support builds behind a push to defy the board and elect new company directors put forward by billionaire climate activist Mike Cannon-Brookes. However, AGL's board has told investors it would support only Twidell's candidacy, saying it did not believe the three other nominees would provide the additional experience and skills necessary to ensure the successful implementation of the board's strategy. The board has also argued Grok was seeking too much board representation and has cast doubts over the candidates' independence.

A growing number of influential proxy advisers - firms that guide institutional investors on how to vote on board appointments, executive pay and other corporate matters - have backed most or all of Grok's candidates. Institutional Shareholder Services (ISS) recommended backing all four nominees of Grok's and the reasons for support include that they are independent directors, they have relevant and appropriate skills and experience which shareholders may consider will benefit board deliberations, and the company and shareholders as a whole. In addition, two other prominent proxy advisers, Ownership Matters and CGI Glass Lewis, recommend backing three of Grok's candidates - Twidell, Schott and Holman - but not Pollaers.

The Australian Shareholders Association, representing smaller retail investors, said it would vote undirected proxies in favor of Twidell and Schott, but was undecided on Holman and Pollaers.
