The company said, "Rentech has made significant progress on agreements for the licensing and commercialization of certain of its energy technologies. As those discussions progress, Rentech is evaluating alternatives for its technology portfolio, with the assistance of advisors. The prospective benefits of a licensing and commercialization partnership are being assessed in comparison to any incremental costs required by such a partnership, and in comparison to the prospective benefits and costs of alternatives for the technology portfolio. Rentech is currently planning for R&D spending for 2013 in the range of $10M. Successful licensing and commercialization agreements may require R&D spending in excess of that amount, if such expense is justified by the estimated benefits. Rentech expects to choose and implement the highest-value alternative during the first half of 2013."
