Cambridge, MA, Monday, March 15, 2010 -  Molecular Insight Pharmaceuticals, Inc. (NASDAQ: MIPI), a biopharmaceutical company discovering and developing targeted therapeutic and imaging radiopharmaceuticals for use in oncology, announced today the Company received a letter from The NASDAQ Stock Market on March 9, 2010 notifying the Company that for the 30 consecutive business days preceding the date of the letter the Company's listed securities did not meet the minimum $50 million Market Value of Listed Securities requirement for continued listing on the NASDAQ Global Market pursuant to Listing Rule 5450(b)(2)(A).  In accordance with NASDAQ Marketplace Rules, Molecular Insight has a grace period of 180 calendar days to regain compliance.  NASDAQ will deem the Company to have regained compliance with such requirement if the Company's market value of listed securities ("MVLS") closes at $50 million or more for at least ten consecutive business days prior to September 7, 2010.  This notification does not impact the listing of Molecular Insight's common stock at this time.  The Company's common stock will continue to trade on the NASDAQ Global Market under the symbol "MIPI" during this period.     

Molecular Insight intends to actively monitor its MVLS between now and September 7, 2010, and will consider available options to resolve the deficiency and regain compliance with the MVLS Rule.  In the event that the Company is unable to regain compliance with the MVLS Rule prior to September 7, 2010, the Company plans to apply to transfer its common stock to the NASDAQ Capital Market provided that it satisfies the requirement for continued listing on that market.  There can be no assurance that the Company will be able to reestablish or maintain compliance with listing criteria on either NASDAQ market.
