SigmaTron International, Inc. Reports First Quarter Financial Results for Fiscal 2012

ELK GROVE VILLAGE, Ill., Sept. 13, 2011 (GLOBE NEWSWIRE) -- SigmaTron International, Inc. (Nasdaq:SGMA), an electronic manufacturing services company, today reported revenues and earnings for the fiscal quarter ended July 31, 2011.

Revenues increased to $38.9 million in first quarter of fiscal 2012 from $38.1 million for the same quarter in the prior year. Net income decreased to $240,961 for the period ended July 31, 2011 compared to $857,989 for the same period in the prior year. Basic and diluted earnings per share for the quarter ended July 31, 2011, were both $0.06, compared to $0.22 for both for the same quarter ended July 31, 2010.

Commenting on SigmaTron's first quarter fiscal 2012 results, Gary R. Fairhead, President, Chief Executive Officer and Chairman of the Board, said, "The first quarter continued the trend of weak but profitable quarters. Both the revenue and net income results for the fourth quarter of fiscal 2011 and the first quarter of fiscal 2012 were roughly the same. The pricing pressures from both customers and vendors remain and going forward we have started to see a general softening in demand. It would appear that the slowing economy we have been reading and hearing about is reality.

"As we did during the last economic downturn, we will continue to monitor the situation and adjust our cost structure consistent with the short-term pressures and our long-term objectives. We continue to see new opportunities for all of our locations and the hope is that some of those will provide new revenue to help offset the general softening we are seeing. Several of those opportunities have been awarded to SigmaTron, and we believe we are in an excellent position to capture others.

"Since our last press release, both John Chen and Carl Zemenick decided to resign from our Board of Directors for personal reasons. John was on our Board since we went public in 1994 and Carl joined our Board in 2001. I want to thank both of them on behalf of my fellow directors and stockholders for their many years of service and dedication to SigmaTron.

"In light of John's and Carl's decisions to resign, the Board has decided to increase the number of directors of the Company from five to seven, effective immediately. We have announced the addition of Barry Horek, Paul Plante, Bruce Mantia and Linda Frauendorfer to SigmaTron's Board. Their bios are available as part of our August 22, 2011 8-K filing. Linda is also SigmaTron's CFO. Also, as part of the changes to the Company's Board of Directors, I was elected Chairman of the Board. I believe that all of the new Board members bring experience and skill sets to the Board that will serve the Company well and I am pleased that we were able to attract such a qualified group.

"While it appears that volatile and difficult times will continue for at least the short-term, I continue to be optimistic about SigmaTron's long-term prospects. We remain well positioned with a competitive cost structure, which I believe will benefit all stockholders long-term."
