ANN ARBOR, Mich., May 5, 2008 (PRIME NEWSWIRE) -- Aastrom Biosciences, Inc. (Nasdaq:ASTM), a leading regenerative medicine company, today announced that its Board of Directors will withdraw its proposal to shareholders for approval of the grant of discretionary authority to Aastrom’s Board of Directors to amend the Company’s Restated Articles of Incorporation to effect a reverse stock split. A Special Meeting of Shareholders had been convened on April 8, 2008 and adjourned until May 6, 2008 to allow more time for shareholders to cast their votes on the proposal. More than seventy-five percent (75%) of the shares that were actually voted were cast in favor of the reverse stock split proposal. However, approval of two-thirds (or 66-2/3%) of all outstanding shares was required by Aastrom’s charter for this proposal. Due to the high number of outstanding shares that were not voted at all, the two-thirds requirement was not obtained.
