Recent Company Highlights:

• The Company entered into a 3-year Preferred Provider Agreement (PPA) agreement with KDC Solar LLC to serve as their preferred provider of EPC and operations and

maintenance (“O&M”) services. The agreement establishes a minimum commitment for KDC Solar to offer 150 megawatts of SEF projects for SPI’s consideration, and sets as a goal for KDC Solar and SPI to potentially develop a total of 300 megawatts in SEF projects across New Jersey and New York. Under the PPA, SPI and LDK have agreed to provide construction financing and facilitate long-term financing, supported by LDK, of up to $750 million for projects subject to the PPA.

• The Company began construction of an 8 megawatt, single-axis tracker utility-scale solar energy facility near Palm Springs, California

• The Company announced that it had been awarded a 1.69 megawatt project in New Jersey

Management Comments:

The second quarter 2011 results continue to reflect the build out of projects awarded prior to the LDK transaction being finalized. While revenues continue to grow the second quarter gross project margins reflect legacy build costs that should improve as the benefits of the LDK supply chain and capital start to be reflected in our operations. Our pipeline of projects is strong and the Company remains well positioned to grow substantially over the remainder of 2011 and well into 2012.

2011 Outlook:

The Company previously provided guidance for the fiscal 2011 of $70 million in net sales. Based on the first half of fiscal 2011 results and the outlook for the balance of the year, the Company reaffirms its guidance.
