Results for the three months ended March 31, 2011

Total revenue rose to $2.7 million in the second quarter of fiscal 2011, an increase of 154% compared to $1.1 million in the second quarter of fiscal 2010.

Net loss for the second quarter of fiscal 2011 was $1.2 million, or $(0.02) per basic and diluted common share, unchanged from the second quarter of fiscal 2010. GAAP results for the second quarter of fiscal 2011 included non-cash items such as stock-based compensation expense, financing costs, amortization expense and foreign exchange losses.

On a non-GAAP basis, net income in the second quarter of fiscal 2011 was $64,000, compared to a non-GAAP net loss of $(666,000) in the second quarter of fiscal 2010. Non-GAAP net income from operations for these periods excluded the impact of non-cash stock-based compensation expense, non-cash financing costs and the interest expense incurred on long-term debt.

Current assets, primarily accounts receivable related to our PHEV battery packs, increased by approximately $1.5 million.

"During the quarter, we produced more battery packs for the Ram PHEV and the second PHEV for an iconic large automotive North American platform, as well as our large-scale energy storage market customer." commented Dr. Sankar Das Gupta, Chief Executive Officer. "We believe that the demand for our clean non-NMP manufacturing process technology will grow, and as a result of the re-purchase of our manufacturing license to the Nordic countries, we have now positioned ourselves to sell unfettered licensing rights to all of Europe."

Business Highlights:

• Plug-in Hybrid Electric Vehicles ("PHEV's"): As North America moves toward a target of one million PHEV's, Electrovaya continues to deliver on the Ram platform as well as another iconic large OEM platform.

• Energy Storage for a Large US Utility: Good progress continues on the design and build, with delivery slated for late summer of 2011. Energy storage opportunities with several other utilities for similar MWh scale energy storage systems are now under discussion.

• Joint venture opportunities: Discussions continue concerning joint venture opportunities globally. There is increasing interest in building low-cost, nimble, green manufacturing facilities.
