Exhibit 99.1
ALLIED WORLD REAFFIRMS ITS SUPERIOR BID AND COMMENTS ON
NATIONAL INDEMNITY PROPOSAL TO ACQUIRE TRANSATLANTIC
Zug, Switzerland — August 7, 2011— Allied World Assurance Company Holdings, AG (NYSE: AWH) today
issued the following statement in response to National Indemnity Company’s proposal to acquire
Transatlantic Holdings, Inc.:
President and Chief Executive Officer Scott Carmilani said, “We reaffirm our full commitment to the
terms of the Allied World/Transatlantic Holdings merger agreement. We believe this combination
provides superior financial and strategic benefits and the opportunity for shareholders of both of
our companies to participate in the considerable upside potential of the combined company. In
contrast, National Indemnity’s proposal is, at best, opportunistic and seeks to acquire
Transatlantic for cash at a significant discount to book value, leaving Transatlantic shareholders
no upside potential.
“We are on target to close our merger of equals transaction as quickly as possible in the fourth
quarter and look forward to, together, generating attractive long term returns for our
shareholders.”
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.
MacKenzie Partners, Inc. is acting as proxy advisor to Allied World.
