Welcome to the Grant Thornton 2023 Transparency Report. It is a privilege to take on the role of Chief Executive Officer (’CEO’) from 1 January 2024. I am passionate about driving the firm forward with an enhanced focus on innovation, sustainability, and quality.

2023 has been another year of growth and development for our firm. It has been a positive year from a quality perspective in particular, and this demonstrates the effect of our continued focus on and investment in quality.

While it is encouraging to see these results through periods of profound change and disruption – including e.g. geopolitical challenges, the cost of living crisis, the pace of Artificial Intelligence advancement – our firm needs to continue to adapt and evolve to effectively manage the heightened risks and challenges that we face. This will also allow us to continue to support our people, our clients, and our communities.
