MedImmune Named One of Maryland's Fastest Growing Technology Companies in Deloitte Technology Fast 50 Program

GAITHERSBURG, Md., Oct. 11 /PRNewswire-FirstCall/ -- MedImmune, Inc. (Nasdaq: MEDI) has been named to Maryland's Technology Fast 50 Program for the 8th year in a row. The Technology Fast 50 is a ranking of the 50 fastest growing technology companies in the area by Deloitte & Touche LLP. This year's rankings are based on the percentage of growth in fiscal year revenues for the five year period of 1999-2003. Wilmer, Cutler, Pickering, Hale and Dorr is the sponsor for this year's Maryland Technology Fast 50 program and PR Newswire is the official media partner.

"MedImmune's total revenues surpassed the billion-dollar mark for the first time in 2003," said Lota S. Zoth, MedImmune's chief financial officer. "Exciting accomplishments also included receiving regulatory approval for FluMist(R), the first innovation in influenza vaccine technology in more than 50 years, and substantially advancing our development pipeline."

"In today's economy, double-digit percentage revenue growth is an exceptional accomplishment," said Gary H. Tabach of Deloitte's Technology, Media Telecommunications Practice and Office Managing Partner for Deloitte's McLean, Virginia office. "We commend MedImmune for making the commitment to technology and delivering on the promise of market longevity. We are proud to once again honor MedImmune as a Deloitte Technology Fast 50 winner."

To qualify for the Technology Fast 50, companies must have had operating revenues of at least $50,000 in 1999 and $1,000,000 in 2003, must be public or private companies headquartered in North America, and be a "technology company" defined as owning proprietary technology that contributes to a significant portion of the company's operating revenues (using other companies' technology in a unique way does not qualify); and/or devoting a significant proportion of revenues to research and development of technology.

Winners of the 19 regional Technology Fast 50 programs in the United States and Canada are automatically entered in the Deloitte Technology Fast 500 program, which ranks North America's top 500 fastest growing technology companies.
