LONDON, Sept. 17, 2026 /CourierPR/ -- Sompo International Holdings Ltd. has appointed Nicolas Berg as the new CEO of its UK Insurance business, effective October 1, 2026. Berg will succeed Sarah Stanford, who has led the UK Insurance business through its initial integration period following Sompo’s acquisition of Aspen. Stanford will step down on September 30.
Berg brings extensive experience in the insurance industry, having spent the majority of his 25-year career at AIG. He held various global and regional executive roles, including serving as Head of Liability and Financial Lines for the UK, Lloyd's, and EMEA. Berg also chaired the Insurance Risk Committee and was AIG’s Chief Claims Officer for North America.
Alessa Quane, CEO of International Markets at Sompo, praised Berg's appointment, stating, "As an established insurance executive with deep industry knowledge and significant UK and global market experience, Nic brings a dynamic and forward-looking approach to leadership. He will play a critical role in advancing our strategy, accelerating our momentum, and positioning Sompo as a leading commercial insurer in the UK market."
Berg joins Sompo from SCOR Group, where he was most recently CEO of SCOR US and Head of P&C North America. His experience in managing large-scale claims operations and his leadership in the US and North America will be valuable as Sompo seeks to strengthen its position in the UK market.
Stanford, who has been at the helm of the UK Insurance business since the acquisition, will be stepping down after leading the integration period. Her contributions and commitment to the business are acknowledged and appreciated.
