He is currently the company’s president and CEO, roles he assumed in January 2023 after David Long stepped down as CEO.
He will now also succeed Long as chairman and director upon Long’s retirement.
Sweeney said: “David’s tenure has been defined by his unwavering commitment to excellence and the well-being of our employees. His leadership has transformed challenges into opportunities, ensuring that our core values remain at the centre of everything we do.
“On behalf of our board of directors and the entire organisation, I would like to thank David for a remarkable four decades at the company and wish him and his family the very best in the years to come.”
Long’s career at Liberty Mutual spans four decades.
He became president in 2010, was named CEO in 2011, and took on the role of chairman in 2013.
Founded in 1912 and based in Boston, Liberty Mutual is said to be the ninth-largest global P&C insurer based on gross written premium for 2024.
As of 31 December 2024, the company recorded $50.2bn in annual consolidated revenue.
Liberty Mutual employs more than 40,000 people across 29 countries.
Its offerings include a broad range of insurance products and services such as commercial automobile, commercial multiple-peril, commercial property insurance, general liability, homeowners, personal automobile, reinsurance, specialty lines, surety and workers compensation.
Last month, the company announced plans to market and sell all personal lines products under the Liberty Mutual brand by 2026.
This will result in the retirement of the Safeco Insurance brand, part of the company’s independent agent channel since its acquisition in 2008.
