EXHIBIT 99.1 Contact: Justin Cressall Treasurer (441) 298-0753 PLATINUM UNDERWRITERS HOLDINGS, LTD. REPORTS THIRD QUARTER 2004 FINANCIAL RESULTS HAMILTON, BERMUDA, NOVEMBER 8, 2004 - Platinum Underwriters Holdings, Ltd. (NYSE: PTP) today reported results for the third quarter ended September 30, 2004. Summary of the results for the quarter are as follows: - Net loss was $69.8 million. - Basic net loss per common share was $1.62. - GAAP combined ratio was 124.8%. - Net premiums written were $440.5 million. Net premiums written for Platinum's Property and Marine, Casualty and Finite Risk segments for the quarter ended September 30, 2004 were $120.6 million, $172.0 million and $147.9 million, respectively, representing 27.4%, 39.0% and 33.6%, respectively, of our total net premiums written. Combined ratios for these segments were 164.2%, 95.9% and 116.1%, respectively. During the quarter the Company recorded an estimated after-tax negative impact from hurricanes Charley, Frances, Ivan and Jeanne of approximately $145 million. The impact of the hurricanes for both the quarter and nine months ended September 30, 2004 was as follows: gross losses of $186 million, additional premiums earned of $20 million and reduction in profit commissions of $10 million. Hurricane losses adversely impacted the quarterly combined ratio by approximately 41.6 percentage points. Due to the unusual size and frequency of the recent hurricanes, the Company has received relatively few claims advices from its brokers and clients. As a result, the estimated impact is based on reported losses to date, commercial and proprietary catastrophe modeling and industry losses of approximately $28 billion. Consequently, the ultimate impact on the Company's results arising from these events may differ materially from the current estimate. The Company recently evaluated the negative impact of the hurricanes in light of an excess-of-loss retrocessional contract which provided aggregate coverage to the Company. Based on results of operations for the quarter ended September 30, 2004 a cession to the contract was indicated; however, that cession was unlikely to produce a significant economic benefit to the Company and accordingly the Company commuted the contract effective November 8, 2004. Results for the quarter ended September 30, 2004 reflect no benefit from this contract. 2 As of September 30, 2004 total assets were $3,294.3 million, of which cash and fixed maturity investments were $2,374.3 million, an increase of $812.5 million and $583.8 million from their respective balances as of December 31, 2003. Net investment income was $21.4 million for the quarter ended September 30, 2004. As of September 30, 2004 shareholders' equity was $1,088.5 million and book value per share was $25.30. Shareholders' equity increased $21.3 million or $0.51 per share from their respective balances as of December 31, 2003. Steven H. Newman, Chairman of the Board, commented: "Despite our hurricane losses, Platinum distinguished itself by achieving a modest underwriting profit on a year to date basis. This serves to confirm the quality and diversity of our underwriting commitments." Gregory Morrison, Chief Executive Officer, commented: "While our results this quarter were dominated by the losses arising from the hurricanes, these losses were consistent with the size of our portfolio and our position in the market. We are encouraged by the underlying growth of our business and the opportunities we see for the future. Market conditions should provide us with a strong upcoming January reinsurance renewal season." The results for the quarter ended September 30, 2004, compared to the quarter ended September 30, 2003 are as follows: - Net income decreased $107.6 million and the combined ratio increased 39.4 percentage points, largely as a result of the significant catastrophe losses incurred in the current period. - Net premiums written increased $159.2 million, or 56.6%, driven by an increase in all three segments. Net premiums earned rose $110.8 million or 40.7%. - Net investment income increased $6.6 million or 45.0%. Summary of the results for the nine months ended September 30, 2004 are as follows: - Net income was $34.9 million. - Basic and diluted net income per common share was $0.81 and $0.78, respectively. - GAAP combined ratio was 99.6%. - Net premiums written were $1.3 billion. The results for the nine months ended September 30, 2004, compared to the nine months ended September 30, 2003 were as follows: - Net income decreased $60.1 million and the combined ratio increased 13.9 percentage points, largely as a result of the significant catastrophe losses incurred in the current period. - Net premiums written increased $302.5 million, or 31.9%, driven by an increase in all three segments. Net premiums earned rose $225.3 million or 28.5%. 3 - Net investment income increased $15.9 million or 37.4%. Updated Guidance Based on the third quarter results, the current industry environment, the mix of business underwritten and in the absence of any unusual catastrophe activity, Platinum estimates that net premiums written for 2004 will be approximately $1.6 billion, and its GAAP combined ratio for 2004 will be approximately 97%. Platinum expects its combined portfolio of cash and fixed maturity investments to be approximately $2.5 billion at year-end 2004. On this basis Platinum now projects that earnings for 2004 will be approximately $1.75 per diluted common share based on an estimate of 51,000,000 diluted shares.
