Management Commentary "It is clear that 2012 was a challenging year for the company," said Real Goods Solar CEO Kam Mofid. "In the first half of 2012, we struggled to meet our financial objectives due to challenges with the Alteris integration, while also managing a number of key organizational and process changes. However, by the end of the second half, we overcame these challenges and achieved major improvements in Q4 that set the stage for a strong 2013. "I am proud of what our employees have achieved, as well as the passion and dedication everyone has demonstrated in driving this turnaround. In the fourth quarter, we not only reduced SG&A significantly, but improved the topline, achieved major wins in the commercial sector, and ended the quarter in a much stronger cash position than the prior quarter. We also developed and began to deploy a well-defined and clear roadmap toward sustainable and profitable growth both in residential and commercial markets.
