Cereplast Reports Preliminary First Quarter 2013 Revenue Results: Exceeds Revenue for Entire 2012 Fiscal Year

EL SEGUNDO, Calif., Apr. 17, 2013 — Cereplast, Inc. (OTCQB: CERP) (the “Company”), a leading manufacturer of proprietary biobased, compostable and sustainable bioplastics, today announced preliminary revenue for the first quarter ended March 31, 2013. Cereplast expects to report 2013 first quarter revenue of approximately $900,000 to $1 million, exceeding total revenue for the entire 2012 fiscal year.

According to management, approximately 65% of this revenue was generated in Italy due to the demand created by the recently published Application Decree, which requires merchants to discontinue the use of traditional single-use plastic bags in favor of bioplastic bags or other alternatives. Sanctions for non-compliance will be enforced beginning the end of May 2013 and management estimates that as a result, the Company will experience an increase in demand for its Cereplast Compostables^® blown film resins during the second half of 2013 as merchants are forced to transition to bioplastic alternatives.

Based on certain provisions, including current competition, current production capacity, a full production staff and sufficient working capital, management estimates that the Company’s total addressable opportunity for Italy alone exceeds $50 million annually out of a total addressable market for compostable blown film grades in the country that exceeds $500 million per year.

Cereplast Chairman and CEO Mr. Frederic Scheer commented, “We are pleased with our encouraging preliminary revenue results during the first quarter of 2013 and are optimistic for the remainder of 2013. In Italy alone, we conservatively estimate our market opportunity to be approximately $50 million. Additionally, we expect other European nations to enact similar mandates which will exponentially increase our opportunity in Europe. We are excited about these favorable trends and will provide future updates as significant events occur.
