Cereplast Reports Second Quarter 2011 Results
- Grew Second Quarter Net Sales to $7.6 Million vs. $646,000 a Year Ago -
- Reiterates 2011 Annual Revenue Guidance Ranging from $28.0 Million to $34.0 Million -

EL SEGUNDO, Calif. — Aug. 15, 2011 (GLOBE NEWSWIRE) — Cereplast, Inc. (NASDAQ: CERP), a leading manufacturer of proprietary biobased, compostable and sustainable plastics, reported financial results for its second quarter ended June 30, 2011.

Frederic Scheer, Chairman and CEO of Cereplast, said, “For the second quarter of 2011, we grew net sales more than ten-fold over the same period a year ago reaching $7.6 million. This marks the second consecutive quarter we posted net sales greater than the $6.3 million reported for all of 2010. As such, we are well on track to achieve our annual revenue guidance ranging from $28.0 million to $34.0 million. Worldwide regulation is fueling demand for bioplastics, and we are gaining traction. We are focused on executing supply and distribution agreements to build critical mass. After the close of the quarter, we secured another distributor in Europe, bringing the total number of supplier and distribution agreements announced in 2011 to six.”

“Governing bodies all over the world are demanding the use of biodegradable/compostable products. The movement has started with bags and is expanding to include flexible and rigid packaging. Near-term, we expect the majority of growth to come from Europe, which is already facing a shortage of compostable bags. To capture this opportunity, in addition to aligning with distributors, we are working to increase capacity. Planning has begun for a 100,000 ton manufacturing plant in Italy. We remain on track to begin phase one production of 50,000 tons in late 2012.”

Recent Operating Highlights

•

Raised $12.5 million gross proceeds in May through the issuance of 7% senior subordinated convertible notes due June 1, 2016.

•

Announced plans, in May, to secure an Italy-based bioplastic manufacturing plant to create efficiencies and to continue expansion in the European market and, in July, gained access to the facility to begin preliminary improvements. Management expects to fund the Italian operations investment via a mix of European bank debt financing and local government subsidies, and to close the transaction late in the third quarter.

•

Signed distribution agreement with Polimernet Plastik Ltd., in July, to supply Cereplast bioplastic resins to the Turkish market.

•

Introduced the Bioplastics Icon:

•

Established, in April, a new trademarked icon with Cereplast’s “Make Your Mark” competition. Similar to the use of the recycling symbol, the icon is intended to designate and identify bioplastic material.

•

Launched online forum in July enabling the public to interactively discuss the symbol’s proposed usage guidelines and licensing requirements.

Financial Results Second Quarter 2011

For the second quarter of 2011, net sales grew to $7.6 million, compared to $646,000 for the second quarter of 2010. This increase reflects the anticipated growth in order flow. Gross profit for the second quarter of 2011 was $923,000, or 12.1% of net sales, compared to 30.8% for the second quarter of 2010 and 9.7% in the first quarter of 2011. The expected year-over-year gross margin decrease reflects the company’s stated strategy to offer introductory pricing to certain key customers while Cereplast strives to gain critical mass, and the sequential gross margin improvement reflects operational efficiencies, and positive pricing trends. Second quarter 2011 net loss was $2.4 million, or $0.15 per share, compared to a net loss of $1.7 million, or $0.15 per share in the same period a year ago.

Six Months Ended June 30, 2011 Financial Results

Net sales for the first six months of 2011 were $14.9 million, compared to $936,000 for the same period a year ago. Gross profit was $1.6 million, or 10.9% of net sales, compared to $291,000, or 31.1% for the same period a year ago. Net loss was $4.1 million, or $0.27 per share, compared to a net loss of $3.4 million, or $0.32 per share in the same period a year ago.

In May, the company raised $12.5 million gross proceeds through the issuance of senior subordinated convertible notes. Net cash used in operating activities for the second quarter of 2011 was $13.7 million, compared to $3.2 million for the same period in 2010, reflecting the expected increase in accounts receivable amounts due to sales growth.

At June 30, 2011, total cash and cash equivalents were $13.1 million, compared to $2.4 million at December 31, 2010. At June 30, 2011, working capital reached $26.0 million, compared to $5.2 million at December 31, 2010. Shareholders’ equity at June 30, 2011 was $14.8 million, compared to $6.9 million at December 31, 2010.

Outlook

“The demand for compostable bioplastics continues to rise globally based on regulation and independent of oil prices. In fact, European Bioplastics estimates the largest bioplastics market, Europe, is growing at roughly 20% each year. With our current manufacturing plant, we are well positioned to capture demand today. Nonetheless, we are preparing for the future and believe our Italian operations will increase our foothold in Europe,” concluded Scheer.

The company expects to exit the fourth quarter of 2011 with gross margins of 20% or higher. In addition, management reiterated its annual 2011 revenue guidance of $28.0 million to $34.0 million, representing a significant increase over its 2010 net sales of $6.3 million.
