EXHIBIT 99.1 PMA CAPITAL [LOGO] Mellon Bank Center Suite 2800 1735 Market Street Philadelphia, PA 19103-7590 PRESS RELEASE - -------------------------------------------------------------------------------- For Release: Immediate Contact: William Hitselberger (215) 665-5070 PMA Capital Announces Reserve Charge and Suspension of Common Stock Dividend Philadelphia, PA, November 4, 2003- Following a comprehensive review of its loss reserves, PMA Capital (NASDAQ: PMACA) announced today that it will record a pre-tax charge of approximately $150 million primarily to strengthen PMA Re's loss reserves at September 30, 2003. As a result of this charge, the Company has decided to suspend its common stock dividends at the current time. The Company is exploring strategic alternatives and has announced that it has engaged Banc of America Securities LLC to assist it in this activity. During the third quarter, the Company's internal actuaries conducted their periodic comprehensive reserve review, which included an extensive review of carried reserves for accident years 1997-2000. The Company also had an independent actuarial firm conduct an evaluation of PMA Re's traditional property and casualty loss reserves, which supported the Company's conclusion. PMA Re's reserve charge relates to higher than expected underwriting losses in the reinsurance operations, primarily from casualty business written in accident years 1997 through 2000. The Company also completed its review of the loss reserves at The PMA Insurance Group, and determined that no reserve adjustments were necessary. The statutory capital of The PMA Insurance Group will not be affected by the charge. As a result of this charge, the Company will evaluate the recoverability of its deferred tax asset at September 30, 2003. The Company will also be evaluating the effect of this action, including any ratings actions, on its ongoing businesses, liquidity and capital resources. The Company is currently engaged in discussions with the Pennsylvania Insurance Department regarding the operations of its insurance subsidiaries.
