Losers

Energy Conversion Devices, Inc. (ENER) stock plunged 22.47 percent to $2.45 in the after-market trading, as it cut third quarter production of thin-film solar products on changes in solar incentive regime in France and Italy. The company reduced its third quarter production to 25 megawatts, and is also aggressively pulling back on its cost structure.

The dramatic and abrupt shift in the French and Italian solar incentive structures has impacted our business and forced us to reconsider our near-term financial outlook. Recent events have injected disruptive uncertainty into the markets which is causing financing sources to put projects on hold and may impact as much as 50 percent of this quarter's forecasted revenue, said Mark Morelli, Chief Executive of Energy Conversion Devices.

We expect better visibility on the timing of our projects after the announcement of the new Italian feed-in-tariff program and the French tender process. Nevertheless, for the March quarter, we are reducing production to 25 megawatts and are also aggressively pulling back on our cost structure. Thus our financial results will be affected due to restructuring and factory under-utilization charges, said Morelli.
