‘Take Back Control’: The implications of Brexit uncertainty on investor perception of ESG reputational events

This study examines the impact of Brexit on investor reactions to Environmental, Social and Governance (ESG) events in UK companies. Post‐Brexit, investors show reduced sensitivity to ESG incidents, suggesting relaxed corporate accountability for ESG disasters. We observe varied investor responses to different ESG events, with most having less financial influence after Brexit. This research informs regulators, stakeholders and policymakers in the post‐Brexit era, emphasising the need for strong ESG regulations and communication in influencing investor behaviour. It contributes to understanding the relationship between regulatory changes, corporate reputation and investor reactions post‐Brexit.
