GAITHERSBURG, Md., Oct 21, 2004 (PRNewswire-FirstCall via COMTEX) -- MedImmune, Inc. today announced that product sales for the 2004 third quarter increased 12 percent over the 2003 third quarter to $92 million, primarily due to a 25-percent increase in sales of Synagis (palivizumab) to $61 million. Sales of Ethyol(R) (amifostine) increased four percent to $21 million. Total revenues for the 2004 third quarter were $93 million versus $99 million in the 2003 third quarter. The 2003 quarter included $17 million in other revenues, comprised primarily of milestone and other payments for FluMist (Influenza Virus Vaccine Live, Intranasal) from Wyeth, the company's former co-promotion partner for the vaccine.

Product sales for the first nine months of 2004 grew 12 percent to $666 million, driven primarily by a 10-percent increase in sales of Synagis to $539 million. In the first nine months of 2004, sales of Ethyol were $71 million. Through September 30, 2004, FluMist revenues totaled $33 million, mostly from sales recognized in the first and second quarters of 2004 for vaccine sold in the 2003/2004 flu season. Total revenues for the 2004 nine-month period increased four percent to $675 million from $647 million in the 2003 nine-month period.

"We continue to make significant progress advancing our development-stage candidates," stated David M. Mott, president and chief executive officer. "We are particularly pleased to have initiated our Phase 3 studies for CAIV-T, which if successfully developed, could begin to contribute meaningfully to our revenues and earnings in 2007. We look forward to further expansion in our pipeline in the near future as we strive to introduce three new products to market by 2009."

In connection with the dissolution of MedImmune's relationship with Wyeth for the development and marketing of the company's influenza vaccine technology in the second quarter of 2004, MedImmune identified certain charges that would affect its results for the remainder of 2004. These included estimated costs associated with the impairment of intangible assets and acquired in-process research and development (IPR&D), as well as technology transfer and transition expenses. In the discussion below, MedImmune has provided the overall results for both the third quarter and first nine months of 2004 with and without the impact of these charges, as well as a reconciliation in the accompanying schedules so that the underlying trends in the operations of the business can more readily be identified.

Additional Results for the 2004 Third Quarter

For the third quarter of 2004, MedImmune reported a net loss of $65 million, or $0.26 per share, compared to a net loss of $16 million, or $0.07 per share, for the third quarter of 2003. Excluding the charges associated with the termination of the Wyeth agreements, the net loss for the 2004 third quarter was $55 million, or $0.22 per share.

Gross margins on product sales were 56 percent in the 2004 quarter and 63 percent in the 2003 quarter. The decrease in gross margins is primarily due to the permanent write downs of 2004/2005 FluMist seasonal inventory produced in the 2004 third quarter.

Research and development (R&D) expenses increased to $73 million in the 2004 quarter from $54 million in the 2003 quarter. The increase in R&D expenses is related to a large number of new and ongoing clinical and preclinical studies, particularly for CAIV-T, Numax and Vitaxin.

Selling, general and administrative (SG&A) costs increased to $68 million in the 2004 third quarter from $52 million in the 2003 quarter. The increase is due primarily to increases in programs associated with the reacquisition of the influenza vaccines franchise from Wyeth, including the expansion of the pediatric commercial organization, as well as new marketing and medical education programs related to Synagis and FluMist.

Additional Results for Nine-Month Period Ended September 30, 2004

For the first nine months of 2004, MedImmune reported a net loss of $54 million, or $0.22 per share, compared to net income of $107 million, or $0.42 per diluted share in the first nine months of 2003. Excluding the charges associated with the termination of the Wyeth agreements, MedImmune's net earnings in the first nine months of 2004 were $27 million, or $0.11 per diluted share.

Gross margins on product sales for the 2004 nine-month period were 65 percent compared to 73 percent for the 2003 nine-month period. The decline in gross margins is primarily related to the cost of sales for 2003/2004 seasonal sales of FluMist in the first quarter of 2004 and the permanent write downs of 2004/2005 FluMist inventory produced in the first nine months of 2004.

R&D expenses for the first nine months of 2004 were $179 million versus $115 million in the 2003 period. The increase in R&D expenses is related to a large number of new and ongoing clinical and preclinical studies, particularly for CAIV-T, Numax and Vitaxin.

SG&A expenses in the 2004 nine-month period increased to $250 million from $216 million in the 2003 nine-month period, due primarily to costs associated with expanding the pediatric commercial organization and increased marketing activities, as well as increased legal costs.

Other operating expenses in the 2004 nine-month period decreased to $6 million from $25 million in the 2003 nine-month period due to the shift in costs of FluMist manufacturing that are included in inventory and cost of goods sold this year, but were expensed as other operating costs in the first quarter of 2003.

Cash and marketable securities at September 30, 2004 were $1.6 billion, down from $1.9 billion at December 31, 2003, primarily due to the redemption of $169 million in MedImmune Vaccines convertible debt in the 2004 first quarter, payments associated with the reacquisition and transition of the influenza vaccines franchise, capital expenditures, and the repurchase of approximately $15 million of our common stock during the 2004 third quarter.

DISCLOSURE NOTICE: The information contained in this document is as of September 30, 2004 and will not be updated as a result of new information or future events. This document contains forward-looking statements regarding MedImmune's future financial performance and business prospects. Those statements involve substantial risks and uncertainties. You can identify those statements by the fact that they contain words such as "anticipate," "believe," "estimate," "expect," "intend," "project" or other terms of similar meaning. Those statements reflect management's current beliefs and are based on numerous assumptions, which MedImmune cannot control and which may not develop as MedImmune expects. Consequently, actual results may differ materially from those projected in the forward-looking statements. Among the factors that could cause actual results to differ materially are: seasonal demand for and supply of Synagis and FluMist; the commercial viability of FluMist; availability of competitive products in the market; availability of third-party reimbursement for the cost of our products; effectiveness and safety of our products; exposure to product liability, intellectual property or other types of litigation; foreign currency exchange rate and interest rate fluctuations; changes in generally accepted accounting principles; growth in costs and expenses; the impact of acquisitions, divestitures and other unusual items; and the risks, uncertainties and other matters discussed in MedImmune's Annual Report on Form 10-K, as amended, for the year ended December 31, 2003, its quarterly reports on Form 10-Q, its current reports on Form 8-K and other filings with the U.S. Securities and Exchange Commission. MedImmune cautions that respiratory syncytial virus (RSV) disease and influenza occur primarily during the fall and winter months; MedImmune believes its operating results will reflect that seasonality for the foreseeable future. MedImmune is also developing several products for potential future marketing. There can be no assurance that such development efforts will succeed, that such products will receive required regulatory clearance or that, even if such regulatory clearance is received, such products will ultimately achieve commercial success.

  (1) Certain prior period amounts have been reclassified to conform to the
      current presentation.
  (2) Income tax expense (benefit) is recognized using the company's
      projected effective tax rate, which is based on projections of income
      and expense for the entire year.  As required by GAAP, the tax effect
      of separately reported discrete items is recognized in the period in
      which they occur.  Approximately $6.9 million of the acquired IPR&D
      recognized in the second quarter of 2004 is not deductible for income
      tax purposes causing the year-to-date effective rate to differ from
      the projected annual effective rate.  All remaining IPR&D charges
      during 2004 are expected to be deductible.  Depending upon the
      company's reported earnings before taxes for the remainder of 2004,
      the impact of the nondeductible IPR&D may cause the company's year-to-
      date effective tax rate to fluctuate.  The chart below details the
      company's quarterly and year-to-date tax rates for 2004 (in millions):
