        SigmaTron International, Inc. Reports Year End Results

    ELK GROVE VILLAGE, Ill.--(BUSINESS WIRE)--July 12, 2004--SigmaTron
International, Inc. (NASDAQ:SGMA) today reported revenues and earnings
for the fiscal year ended April 30, 2004. Revenues were $100,494,122,
a 5.0% decrease from the prior fiscal year revenues of $105,824,257.
Net income for fiscal 2004 was $5,405,732 compared to $5,714,924 for
fiscal 2003. Diluted earnings per share for fiscal 2004 were $1.53
compared to $1.70 in the prior year.
    Diluted earnings per share for the fourth quarter 2004 were $0.29
per share as compared to $0.69 per share for the fourth quarter of
fiscal 2003. Revenues decreased to $25,227,270 for the fourth quarter
of fiscal 2004 compared to $28,813,611 for the same quarter in the
prior year.
    During fiscal 2004 SigmaTron was required to adopt Financial
Interpretation No. 46 ("FIN46R"), "Consolidation of Variable Interest
Entities" and as a result was required to consolidate the results of
its 42.5% owned affiliate, SMT Unlimited L.P. ("SMTU") for financial
reporting purposes. The consolidation has caused previously reported
periods to be restated for comparison purposes. Because of this
requirement, the usefulness of comparisons between results contained
herein and results published before the third quarter of fiscal 2004
is significantly reduced.
    Gary R. Fairhead, SigmaTron's President and Chief Executive
Officer, observed: "SigmaTron is pleased to report excellent results
for another fiscal year. In fact our Income Before Taxes and Minority
Interest in our affiliate actually increased over our results for
fiscal 2003 in spite of increasing costs from many areas such as
insurance and regulatory requirements.
    "During fiscal 2004 we were successful in completing the
construction of and opening a new plant in Wujiang, China. We have
started limited pilot and production runs and are in the middle of
gaining customer and agency approvals. We believe that the addition of
the China operation uniquely positions SigmaTron for a public company
our size by having wholly owned operations in China, Mexico and North
America plus an established international procurement office in Taiwan
and an affiliate in Silicon Valley. This affords us the ability to
offer customers a unique solution for volume requirements that are too
small for the larger companies in our industry.
    "During the year our Mexican operations successfully consolidated
into one location and continued to perform well. Our Elk Grove Village
operation continued its turnaround, producing an operating profit for
the first time in several years while adding several new customers.
Las Vegas had a down year but remained profitable. Las Vegas is
growing its box-build capabilities and recently expanded its
operations in order to accommodate this effort. Our affiliate, SMTU,
remained profitable. It appears that the Silicon Valley economy
including the telecom segment is starting to recover and this is
encouraging for our affiliate.
    "We face several significant issues going forward. The first is
the requirements put on public companies by the Sarbanes-Oxley Act.
The second is the requirement by Europe to move to a lead-free solder
process. Both issues will impose significant costs on SigmaTron.
However, we remain optimistic about our industry, and the
opportunities we feel we have. We appreciate the continued support
from our stockholders, customers, banks, vendors and employees."
