SigmaTron International, Inc. Reports Second Quarter Financial Results for Fiscal 2011

ELK GROVE VILLAGE, Ill., Dec. 13, 2010 (GLOBE NEWSWIRE) -- SigmaTron International, Inc. (Nasdaq:SGMA), an electronic manufacturing services company, today reported revenues and earnings for the second quarter ended October 31, 2010.

Revenues increased to $38.2 million for the second quarter fiscal 2011 from $30.6 million for the same quarter in the prior year. Net income increased to $586,050 in the fiscal 2011 period compared to $517,298 for the same period in the prior year. Basic and diluted earnings per share were $0.15 for the quarter ended October 31, 2010, compared to $0.14 and $0.13, respectively, for the same quarter in fiscal 2010.

For the six months ended October 31, 2010, revenues increased to $76.3 million compared to $56.9 million for the same period ended October 31, 2009. Net income for the same period in fiscal 2011 was $1,444,039, compared to $114,823 for the same period in the prior year. Basic and diluted earnings per share for the six months ended October 31, 2010, were $0.37 compared to $0.03 and $0.02, respectively, for the six months ending October 31, 2009.

Commenting on SigmaTron's second quarter and six month results, Gary R. Fairhead, President and Chief Executive Officer, said, "I am pleased to report positive results for our second quarter of fiscal 2011.  As indicated in the first quarter press release, the relocation from Hayward to Union City, California, would negatively impact our results in both the first and second quarters of fiscal 2011.  Net income adjusted on a pro-forma basis to exclude relocation expenses for the three and six month periods ended October 31, 2010 was $1,007,763 and $1,999,627, respectively.  The non-GAAP basic and diluted earnings per share, as adjusted, for the first and second quarters of fiscal 2011 equated to $0.26 and $0.51, respectively. Our team in California did an exceptional job of relocating our operations from Hayward to Union City during the second quarter. The relocation was executed as planned and all customer commitments were met.  The Union City facility is fully operational for both existing and new customers as all audits were passed. The one-time relocation expenses are almost entirely behind us and starting in the third quarter, we expect that lease expenses for Union City, California will decrease by $40,000 per month, which was one of the drivers of the move.

"Our revenue for the second quarter was essentially the same as the first quarter, which hopefully indicates some level of stability in the general economy. Our earnings were lower compared to the first quarter, but primarily due to relocation expenses in California.  Our backlog remains stable. Our revenue run-rate over the first two quarters of fiscal 2011 is at the strongest revenue level for two consecutive quarters since the 2008 downturn in the economy.  Revenue has rebounded nicely and is slightly below the revenue level for the first two quarters of fiscal 2009. This is a positive development.

"Going forward, many challenges remain. While it appears that our customers have stabilized their businesses, the continued uncertainty in the economy forces us to remain cautious. Pricing pressures remain with both customers and vendors. We continue to have lead-time issues with several raw material classes.

"However, we continue to have an operations footprint that is attractive to our current and prospective customers, which can help us counter some of the pricing pressures. We continue to work on new programs with existing customers and bid on programs for new customers.

"In closing, I want to thank all of our stakeholders for their continuing support and wish all of you a happy holiday season and a healthy and successful 2011."
