Ascent Solar Announces Completion of Conversion to Streamlined Form S-3

Business Wire, Oct 29, 2007

LITTLETON, Colo. -- Ascent Solar Technologies, Inc. (Nasdaq: ASTI) today announced that the two post-effective amendments it filed last week have been declared effective by the Securities and Exchange Commission. As a result, the exercise of Ascent Solar's outstanding Class B warrants may now resume. Matthew Foster, Ascent Solar's President and Chief Executive Officer, stated: "We are pleased that the post-effective amendments have been declared effective, and we expect that the conversion from 'long form' registrations on Form SB-2 into 'short form' registrations on Form S-3 will result in additional cost savings in the future." Ascent Solar had filed with the Securities and Exchange Commission post-effective amendments to two Form SB-2 registration statements that covered, among other things, the shares of common stock issuable upon exercise of outstanding Class B warrants. The filings did not register additional securities for sale by Ascent Solar, but were intended solely to convert existing registrations on Form SB-2 into less burdensome and less costly registrations on Form S-3.
