11:13 AM ET) SAN FRANCISCO (MarketWatch) -- Sourcefire Inc. FIRE +8.21% shares climbed 9%, to $52.09 Wednesday, in the wake of the cybersecurity company's first-quarter results. Late Tuesday, Sourcefire reported earnings excluding one-time items of 11 cents a share, on $56.2 million in revenue, compared with a profit of 11 cents a share on sales of $46.3 million in the same period a year ago. Analysts had forecast Sourcefire to earn 12 cents a share on $57.4 million in sales. The company attributed its weaker-than-expected results to the effects of the government sequestration, that delayed federal contracts being finalized in March. Analysts Dan Cummins, of B. Riley, said that despite the disappointing federal business, Sourcefire still had "good deal metrics overall" and raised his rating on the stock to buy from neutral.
