SMTC Reports First Quarter Results

TORONTO – May 5, 2011 — SMTC Corporation (Nasdaq: SMTX, TSX: SMX), a global electronics manufacturing services provider, today reported 2011 first quarter unaudited results. Revenue for the quarter was $56.3 million; $5.1 million or 8% lower than the first quarter of 2010. Revenues declined as the Company experienced revenue reductions from customers driven by end market reductions. One of the Company’s larger customers experienced sharply reduced end market demand. The net income for the quarter of $0.7 million compares with net income of $2.1 million for the comparable period last year. Net income includes $364 thousand in restructuring charges related to severance in Canada and Mexico. On an EBITDA basis, earnings were $2.3 million for the quarter compared to $3.2 million a year earlier.

Gross profit for the first quarter was $5.1 million or 9.1% of revenue compared to $6.4 million or 10.4% for the first quarter of 2010 due to the reduction and mix of revenue. Bank debt net of cash increased by $7.1 million in the quarter.

Jane Todd, Senior Vice President, Finance and Chief Financial Officer, commented, “Lower revenues resulted in carrying higher inventory levels which, in turn, drove debt levels temporarily higher in the quarter. We continue to target cash generation and elimination of debt and expect to generate cash through the remainder of 2011.”

“The Board of Directors has actively continued the Chief Executive Office search that commenced at the end of 2010. While doing so, the Interim Office of the Chief Executive Officer is fully engaged in continuing to drive initiatives that we believe will result in increased value for our customers and shareholders”, stated Alex Walker, Chairman of the Board of Directors and

Chairman of the Interim Office of the Chief Executive Officer. “The results this quarter are disappointing and we are committed to aggressively manage costs and restructure to improve financial performance as well as launching several additional initiatives to drive improved results.”

Claude Germain, Member of the Office of the Chief Executive Officer, added, “We intend to focus on continuing to improve the level of service and support we provide to our customers and invest in customer facing activities, while streamlining costs, improving processes and reducing working capital. We are targeting approximately $5 million in annual cost savings and $10 million in working capital improvement by the end of the year as a result of these initiatives.”

Alex Walker concluded, “We believe SMTC will end 2011 with a leaner, more customer focused cost structure, a nearly debt free balance sheet, and improved margins and profitability. With a healthier balance sheet, SMTC will be in a position to consider strategic acquisition opportunities which would leverage our assets and take advantage of the Company’s approximately $100 million in tax loss carry-forwards. Although current results are unsatisfactory, we believe the Company has significant opportunities to create meaningful shareholder value going forward.”

The Company is holding an earnings call today at 5:00 p.m. EDT. Those wishing to listen to the teleconference should access the webcast at the investor relations section of SMTC’s website www.smtc.com. A rebroadcast of the webcast will be available on SMTC’s website following the teleconference.
