Nucleus Names New Deputy CEO

The new deputy CEO is an "exceptional leader" with real commercial and strategic expertise that will help the firm drive its next phase of growth.

UK-based Nucleus Financial Platforms, an independent advisor platform group, has promoted Mike Regan to the newly-created role of deputy CEO, effective immediately.

Regan, who joined Nucleus in 2022 initially as CFO, now acting as chief commercial officer, will retain his current responsibilities. As deputy CEO, he will provide support to CEO Richard Rowney, working with the executive team to lead the business and develop the group strategy.

The creation of this role reflects the ambition and continued growth of Nucleus as “one of the leaders in the sector,” it said in a statement.

Since joining, Regan has helped to transform Nucleus. It has acquired and integrated Curtis Banks and, more recently, Third Financial. He has also led the commercial team in securing new client wins and driving better customer outcomes, leading the group’s ongoing investment in proposition development, the firm said. 

“As we grow and become more complex, promoting Mike to support me as deputy CEO was the obvious choice,” Rowney said. “He’s an exceptional leader who has real commercial and strategic expertise that will help us drive the next phase of our growth, whilst remaining firmly focused on delivering the best possible service for advisors and their customers.”

Regan's promotion follows the appointment in August of Andrew Ring as chief financial officer.
