Exhibit 99.1
ALLIED WORLD REMAINS FULLY COMMITTED TO TERMS OF MERGER
OF EQUALS WITH TRANSATLANTIC
Zug, Switzerland July 18, 2011 Allied World Assurance Company Holdings, AG (NYSE: AWH) today
affirmed that it remains fully committed to the terms of the merger with Transatlantic Holdings,
Inc. (NYSE: TRH), which it believes provides the best value for all shareholders and the best
prospects for long-term growth.
Allied World Chairman, President & Chief Executive Officer, Scott Carmilani, stated, The
TransAllied merger provides significant financial and strategic benefits and the best long-term
value for shareholders of both of our companies. Our transaction fully satisfies the key strategic
goals outlined by Transatlantic with greater certainty. We believe that Validus proposal is
inferior. It cannot provide Transatlantics shareholders with the same value that our merger of
equals can. Validus unsolicited proposal is an attempt to acquire Transatlantic at a significant
discount to book value. In addition, the needed reduction to Transatlantics property catastrophe
business in the inferior Validus takeover to a level compliant with Transatlantics enterprise risk
management risk tolerances would lead to limited property catastrophe writing flexibility.
Allied World noted that both Standard & Poors (A excellent) and Moodys (A2) have made positive
indications relating to Allied Worlds financial strength ratings, and A.M. Best has affirmed our A
Excellent financial strength rating.
Mr. Carmilani continued, The rating agencies have reacted favorably to our superior transaction
indicating that Transatlantics operating companies financial strength ratings will remain
unchanged after the transaction. These stronger indicative ratings (as compared to the indicative
ratings direction under the Validus proposal) will benefit the combined company. With a month of
productive integration planning and Hart-Scott-Rodino clearance already in hand, Transatlantic and
Allied World have established considerable momentum together. We look forward to completing our
merger.
Deutsche Bank Securities Inc. is acting as financial advisor and Willkie Farr & Gallagher LLP and
Baker & McKenzie are acting as U.S. and Swiss legal counsel, respectively, to Allied World.
