Leadership Transition — Sean O'Connor's 22-Year Run and Philip Smith's New Era

StoneX completed a generational leadership change in December 2024, when Philip Smith succeeded founder Sean O'Connor as Group CEO. O'Connor remains as Executive Vice-Chairman of the Board. Understanding both leaders' philosophies — O'Connor's compounding-and-acquisitions doctrine and Smith's commercial-and-payments operator background — is essential context for any candidate trying to understand "where StoneX is headed" in their interview answers.
