SigmaTron International, Inc. Reports Year End Financial Results for Fiscal Year 2011

ELK GROVE VILLAGE, Ill., July 13, 2011 (GLOBE NEWSWIRE) -- SigmaTron International, Inc. (Nasdaq:SGMA), an electronic manufacturing services company, today reported revenues and earnings for the fiscal year ended April 30, 2011. Revenues increased 23.9% to $151.7 million in fiscal year 2011 from $122.5 million in the prior year. Net income decreased to $1.98 million in fiscal year 2011 compared to $2.24 million in fiscal 2010. Diluted earnings per share for the fiscal year ended April 30, 2011 were $0.51 compared to $0.58 in fiscal 2010.

For the fourth quarter of fiscal year 2011, revenues increased to $38.5 million compared to $35.0 million for the same quarter in the prior year. Diluted earnings per share for the fiscal year 2011 fourth quarter were $0.07 per share compared to $0.44 per share for the same period of fiscal 2010.

Commenting on SigmaTron's results, Gary R. Fairhead, President and Chief Executive Officer, said, "While I am pleased to report a profit for the fourth quarter of fiscal 2011, I must also report that the current income trend for the Company is not what we would like to see. While our revenue for the fourth quarter versus the third quarter was modestly up, fully diluted earnings were flat. As I have mentioned in prior press releases, we have seen pricing pressures from both customers and vendors that have continued to squeeze our margins. Our fourth quarter results are continuing evidence of those pressures that we expect to see for at least the balance of this calendar year.

"The results for fiscal 2011 compare favorably to fiscal 2010 after elimination of the gain recorded in 2010 for an insurance settlement. However, our sequential performance dipped from the first six months of this year to the second half of fiscal 2011 with fully diluted earnings at $0.37 and $0.14, respectively, due to the margin pressures described above.

"During the year we achieved several objectives that are worth repeating. We successfully relocated our California operation from Hayward to Union City. The relocation was done efficiently and without any disruption in support of our customers. The new plant layout has increased our productivity and has assisted in attracting interest from many new customers including some in the aviation, defense, and medical markets. These markets continue to be target markets for the Company going forward.

"We have gained new customers at all locations and in most cases, we have started production for them. Most production launches were later than expected, but all show great promise and we currently believe that they will help us in terms of increasing revenue and profits in fiscal 2012. We are continuing to work on methods to reduce our inventory levels and we expect to start seeing positive results from that in the second quarter of fiscal 2012.

"While the recent income trend is disappointing, I do believe that SigmaTron has continued to make progress at all of its operations and remains well positioned when the economy ultimately recovers. Once again, I want to thank our customers, supply chain, banks, our employees and our Board of Directors for their support and efforts during fiscal 2011."
