A123 Systems (AONE +12%), crushed over the last 12 months due to a litany of problems (I, II, III), is rallying post-earnings. Though A123's numbers badly missed estimates and the company reported cash burn of $73M, it also said it has fixed the battery defect that led to a massive recall, and that a federal grant with $120M in remaining proceeds has been extended by 2 years. A123 slashed its 2012 guidance last Friday.
