CLEVELAND, Jan. 11, 2013 (GLOBE NEWSWIRE) -- Athersys, Inc. (Nasdaq:ATHX) announced today that it has filed a shelf registration statement with the Securities and Exchange Commission (“SEC”). The new shelf registration statement will replace a similar registration filed in 2010 that will expire later this month. Athersys currently does not have any immediate plans to offer or sell the securities under this registration statement. As with the previous shelf registration that is due to expire, the replacement registration statement is intended to provide Athersys with financial flexibility to raise capital from the offering of up to 20,000,000 shares of common stock and/or warrants to purchase common stock, which could occur in multiple transactions conducted over an extended period of time. When declared effective, a shelf registration statement gives a company advance regulatory approval to sell securities in one or more separate offerings in amounts and at prices and terms to be determined at the time of the sale.
