NYMAGIC® News - NYMAGIC, INC. Announces Management Succession

New York, March 12, 2010. NYMAGIC, INC. (NYSE:NYM) announced today that its Chief Executive Officer, A. George Kallop, intends to retire on April 2, 2010. He will be succeeded by George R. Trumbull, currently a Director of the Company, and formerly the Company’s Chairman and Chief Executive Officer, who was elected to the position of Senior Executive Vice President of the Company, effective today, and President and Chief Executive Officer of the Company, effective April 2, 2010.

Mr. Kallop commented, “I will be 65 years of age this coming June and had been planning to retire sometime in the near future. My plans, however, were accelerated after a family member became severely ill several weeks ago. George Trumbull, a good friend and loyal business associate was gracious to step in on short notice to assume my duties and facilitate this transition.”

“NYMAGIC has just completed the most profitable year in its history, achieving Net Income of $45.5 million for 2009, and during the fourth quarter of 2009 gross premiums written and net premiums written increased by 8% and 17%, respectively over the prior year. I am leaving the Company in a strong financial condition, with a very professional management team, and well positioned for the future. George Trumbull and I have maintained close contact over these past years, and I am confident that the transition will be a smooth one. I wish George every success.”

Robert G. Simses, the Company’s Chairman said that “Over his almost five years as Chief Executive Officer, George Kallop diversified our product line, successfully navigated the Company through a period of global economic dislocation and served during a period of unprecedented earnings for the Company in 2009. We are sorry to see George leave, but we certainly understand that his family is his first priority.”
