Rentech Files Shelf Registration Statement

LOS ANGELES--(BUSINESS WIRE)--Rentech, Inc. (NYSE AMEX:RTK) today announced it has filed a shelf registration statement on Form S-3, to replace its existing shelf registration which expires on March 31, 2009. The new registration statement, filed with the Securities and Exchange Commission (SEC), if declared effective by the SEC, would allow the Company to sell, from time to time, up to $100 million of various types of securities in one or more offerings. Rentech is not required to offer or sell all or any portion of the securities in the future under the shelf registration statement and will do so only if market conditions warrant, and if Rentech’s needs for capital require such sales of securities. The terms of any offering under the shelf registration statement would be established at the time of any such offering.

The recently filed Form S-3 is intended to give Rentech flexibility to take advantage of financing opportunities when market conditions are favorable to the Company. The use of potential future proceeds from the sale of securities under the shelf registration statement could enable Rentech to accelerate the development of the Company’s planned renewable and fossil synthetic fuels facilities. Rentech has no current agreements, plans or discussions to offer any of the shares covered under the Form S-3 for sale.

The shelf registration statement that has been filed is not yet effective. No securities pursuant to this registration statement may be sold, nor may offers to buy any such securities be accepted prior to the time the registration statement becomes effective. This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. Any offering may be made only by means of a prospectus and a related prospectus supplement which will describe any offered securities and the use of proceeds from the sale of any such securities.
