RICHMOND, Va.--(BUSINESS WIRE)--March 22, 2006--Insmed Incorporated (NASDAQ: INSM): Under NASDAQ Marketplace Rule 4350(b) any Company listed on the NASDAQ Market which receives a going concern opinion is required to press release this information to the public. In compliance with this market rule Insmed announces that in its 10K filed for the year ended December 31, 2005 the Company’s auditor had modified their audit opinion due to a going concern uncertainty, as the Company’s ability to continue as a going concern at the time was dependent upon its ability to raise capital through securities offerings, debt financing, and partnerships and use these sources of capital to fund operations.
