EXHIBIT 99.1 [DYAX LOGO AND LOGOTYPE] CONTACT: Stephen S. Galliker EVP, Finance and Administration, CFO Dyax Corp. (617) 250-5733 sgalliker@dyax.com DYAX CORP. ANNOUNCES FOURTH QUARTER AND YEAR END 2002 FINANCIAL RESULTS AND 2003 GUIDANCE CAMBRIDGE, MA, FEBRUARY 19, 2003 - Dyax Corp. (Nasdaq: DYAX) today announced financial results for the fourth quarter and year ended December 31, 2002. FINANCIAL RESULTS: For the quarter ended December 31, 2002, the Company reported a net loss of $6,377,000 or $0.32 per share as compared to a net loss of $5,933,000 or $0.31 per share in the comparable quarter of 2001. For the fourth quarter of 2002, the Company reported revenues of $10,864,000 as compared to $8,717,000 for the same period in 2001. For the year ended December 31, 2002, the Company reported a net loss of $26,818,000 or $1.36 per share as compared to a net loss of $17,165,000 or $0.89 per share for the year ended December 31, 2001. Revenue for the year ended December 31, 2002 increased 23.8% to $40,908,000 as compared to $33,040,000 for the year ended December 31, 2001. The growth in revenue for fiscal year 2002 was due primarily to increased sales of separations systems and products by Biotage, the Company's chromatography subsidiary, as well as to new and expanded biopharmaceutical research and product collaborations. Dyax ended the fourth quarter and year 2002 with $28,199,000 in cash and cash equivalents, exclusive of restricted cash. Research and development expenses for the fourth quarter of 2002 increased 50.0% to $8,036,000 from $5,356,000 for the fourth quarter of 2001. Research and development expenses for the year ending December 31, 2002 increased 64.3% to $31,920,000 from $19,432,000 for the year 2001. These increases were primarily due to increases in external research and development costs associated with prospective and ongoing clinical trials involving DX-88 and DX-890, the Company's lead product candidates. More specifically, increased costs were incurred due to the initiation of a phase I/II clinical trial of DX-88 for patients undergoing cardiopulmonary bypass (CPB), costs associated with U.S. enrollment into EDEMA1, a phase II 48-patient clinical study of DX-88 for the treatment of hereditary angioedema (HAE), and manufacturing costs associated with the ongoing Phase II trial in Europe for DX-890 in cystic fibrosis (CF). Commenting on Dyax's results, Henry E. Blair, Chairman and CEO said, "We are greatly encouraged by the progress made during 2002. In particular, the advances made in the area of clinical development for DX-88 and DX-890 demonstrate our transition to a biopharmaceutical company from a technology platform company. For DX-88, we reported interim phase II results from our European study in HAE, and as planned, we initiated a phase I/II study of DX-88 in a second indication, CPB. Since year end, we have initiated a larger U.S.-based 48-patient study of DX-88 in HAE, referred to as the EDEMA1 trial, and have begun patient treatment. Notably, both the United States and European regulatory authorities granted orphan drug designation to DX-88 early in 2003 for the treatment of angioedema. Regarding DX-890, we reported initial results of a phase IIa European study in adult CF patients, and have also initiated a second phase IIa' study in Europe for children with CF." Added Mr. Blair, "I'm also very proud of Dyax's success in achieving effective freedom to operate in the important arena of phage display discovery of human antibodies. We concluded a series of cross-licensing agreements with Biosite, Genentech, XOMA and most recently extended our agreement with Cambridge Antibody Technology. These new arrangements should set the stage for a number of new therapeutic antibody collaborations. I believe that Dyax has state-of-the-art libraries and capabilities in this important discovery technology." With respect to the financial results, Mr. Galliker said, "We are pleased that our results are in line with our most recent forecast for the year. We are particularly pleased with the progress made by Biotage, our now self-sufficient separations subsidiary located in Charlottesville, Virginia, that has become a significant financial asset of Dyax. During 2002, Biotage continued its revenue growth and began generating positive operating cash flow in the last two quarters of the year." Mr. Galliker continued with the following guidance for 2003: 2003 GUIDANCE: FINANCIAL OUTLOOK "Overall, our revenues are expected to increase from 20% to 30% in 2003. This growth is composed of a 15% to 20% increase in Biotage revenues and a 25% to 50% increase in the biopharmaceutical segment. We expect continued strength from Biotage's products in its discovery segment, including several new product launches scheduled for early 2003. Projected growth from the biopharmaceutical segment reflects additional anticipated funded research opportunities based on our antibody discovery technology and capacity. We will continue to carefully monitor and manage our cash position. With the cost reduction measures implemented in 2002, we would expect net cash consumption for operations in 2003 in the range of $15 to $20 million, down from $22.8 million in 2002. The Company will also be considering its available alternatives for additional working capital, including selling additional equity or debt securities or selling or leveraging other assets. CLINICAL MILESTONES We expect to report initial results from all four of our active clinical trials during 2003: the European phase II DX-88 study in HAE, the U.S.-based phase II EDEMA1 study of DX-88 in HAE, the U.S. phase I/II study of DX-88 in CPB, and the phase IIa1 study of DX-890 in children with CF. Notably, Dyax is presenting clinical data for the first time at a major medical meeting in March 2003. This data from the European trial of DX-88 in hereditary angioedema will be presented in an oral abstract at the annual meeting of the American Academy of Allergy, Asthma and Immunology (AAAAI)."
