Other Events.

As previously reported, on December 9, 2010, Molecular Insight Pharmaceuticals, Inc. (the “Company”) filed a voluntary petition in the United States Bankruptcy Court for the District of Massachusetts seeking relief under the provisions of Chapter 11 of the United States Bankruptcy Code, Case No. 10-23355. The Company continues to operate its business and manage its properties as a debtor in possession pursuant to sections 1107(a) and 1108 of the Bankruptcy Code. The Company’s Chapter 11 Case is pending before the Honorable Frank J. Bailey.

On April 14, 2011, the Company submitted its unaudited monthly operating report for the period March 1, 2011 through March 31, 2011 (the “Monthly Operating Report”). Exhibit 99.1 to this Current Report on Form 8-K contains a copy of the unaudited Monthly Operating Report as submitted to the Office of the United States Trustee.

The Monthly Operating Report is limited in scope, covers a limited time period and has been prepared solely for the purpose of complying with reporting requirements of the Operating Guidelines and Reporting Requirements for Chapter 11 Cases promulgated by the Office of the United States Trustee. The financial information contained in the Monthly Operating Report is preliminary and unaudited and does not purport to show the financial statements of the Company in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and, therefore, may exclude items required by GAAP. The Monthly Operating Report also does not include footnotes that would ordinarily be contained in the financial statements in the Company’s quarterly and annual reports filed pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Monthly Operating Report contains information for periods that may be shorter or otherwise different from those contained in reports required pursuant to the Exchange Act. The financial information has not been reviewed or otherwise verified for accuracy or completeness by the Company’s independent registered public accountants, and there can be no assurance that the Monthly Operating Report is complete. The Company cautions readers not to place undue reliance on the Monthly Operating Report. The Monthly Operating Report may be subject to revision. The Monthly Operating Report is in a format required by the Office of the United States Trustee and should not be used for investment purposes. The information in the Monthly Operating Report should not be viewed as indicative of future results. The Monthly Operating Report is being furnished for informational purposes only.

Limitation on Incorporation by Reference

Exhibit 99.1 to this Current Report on Form 8-K shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall they be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in the filing.

Forward-Looking Statements

Statements in this Current Report on Form 8-K that are not strictly historical in nature are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements about our pending Chapter 11 filing and those factors identified in our filings with the SEC. Such forward-looking statements involve known and unknown risks, uncertainties, and other factors that may cause the actual results of the Company to be materially different from historical results or from any results expressed or implied by such forward-looking statements. The risks and uncertainties and the terms of any reorganization plan ultimately confirmed can affect the value of our various pre-petition liabilities, common stock and/or other securities. No assurance can be given as to what values, if any, will be ascribed in the bankruptcy

proceedings to each of these constituencies. A plan of reorganization could result in holders of our liabilities and/or securities receiving no value for their interests. All forward-looking statements are qualified in their entirety by this cautionary statement.
