Sompo chief financial officer Nicolas Burnet expressed his excitement at welcoming Leone to the company.

“The combination of his technical expertise, strategic vision and strong leadership skills makes him the perfect fit for this role. I am confident Tom will further advance our investment strategy to ensure the continued financial success of our organization,” said Burnet.

“Mark is leaving behind an exceptional legacy and I would like to thank him for his outstanding leadership and many contributions that built a market-leading investments function for Sompo,” said Burnet.

“I am very pleased that his journey with our organization does not end here. Instead, it transitions into a new phase where Mark has agreed to lead Sompo’s philanthropic efforts.”
