Revenues increased to $52.7 million for the second quarter of fiscal 2013 from $39.9 million for the same quarter in the prior year. Net income increased to $482,834 in the second fiscal quarter compared to $158,267 for the same period in the prior year. Basic and diluted earnings per share were $0.12 for the quarter ended October 31, 2012, compared to $0.04 for the same quarter in fiscal 2012.

For the six months ended October 31, 2012, revenues increased to $100.4 million compared to $78.8 million for the same period ended October 31, 2011. Net income for the same period in fiscal 2013 was $389,690, compared to $399,228 for the same period in the prior year.  Basic and diluted earnings per share for the six months ended October 31, 2012, were $0.10 compared to $0.10 for the six months ended October 31, 2011.

Commenting on SigmaTron's second quarter fiscal 2013 results, Gary R. Fairhead, President, Chief Executive Officer and Chairman of the Board, said, "I am pleased to report that SigmaTron was profitable for the second quarter of fiscal 2013, tripling our earnings per share from the same quarter in fiscal 2012.  These results are after incurring an additional $179,156 in one-time transaction costs related to the Spitfire acquisition.  We expect these costs to end during the third quarter of this fiscal year.

"Speaking of the Spitfire acquisition, we are pleased with the results to date. Customers have accepted and welcomed our combined structure, and we continue to believe that we will have more opportunities in the electronic appliance control market because of the acquisition.  The assimilation of Spitfire into SigmaTron continues on schedule, and we expect that all operations will be fully assimilated by the end of fiscal 2013.

"Going forward, the uncertainty of the election is now behind us but the potential fiscal cliff still looms.  The short-term economic outlook remains status quo, which I would describe as volatile, with continuing pricing and margin pressures and no established long-term economic trends.  As previously disclosed we will continue to manage accordingly and hope for a clearer trend for the economy next year. With all of that said, there is positive news to report.  Several new customers have selected us as their electronic manufacturing services provider of choice. Coupling that good news with the synergy created by the Spitfire acquisition, we continue to believe that we are well positioned for when the economy does start to grow again at a significant rate."
