On February 29, 2012, the Company announced its financial results for the fourth quarter and year ended December 31, 2011. Specifically, First Solar reported a decrease of $345 million in net sales for the fourth quarter, as compared to the previous quarter, “primarily due to the timing of revenue recognition in our systems business and lower for module-only sales.” In addition, the Company disclosed various charges including a charge of $164 million for warranty payments to replace equipment that caused premature power loss in certain panels. The Company spent $125.8 million in the fourth quarter on warranty claims and has put aside $37.5 million to cover future claims.

On these revelations, First Solar shares declined $4.10 per share or 11%, to close at $32.30 per share, on February 29, 2012.
