The increase in net sales reflects a one-time spike in sales from an industrial sector customer that was expected and strong demand from semiconductor equipment sector customers.

Gross profit for the first quarter of 2006 improved to $8.0 million compared to $0.5 million in the first quarter of 2005 and $7.0 million in the fourth quarter of 2005. Gross profit as a percentage of net sales improved to 8.4% for the first quarter of 2006, compared to 0.6% on net sales of $82.7 million in the first quarter of 2005 and 8.3% on net sales of $83.9 million in the fourth quarter of 2005. The improvement in gross profit for the first quarter of 2006 compared with the first quarter of 2005 was primarily attributable to the cumulative impact of restructuring and cost containment actions that were initiated throughout 2005 and supplemented by higher net sales.

Operating income for the first quarter of 2006 was $1.7 million, an improvement of $7.1 million as compared to an operating loss of $5.4 million for the first quarter of 2005. Sequentially, operating income improved $0.4 million compared to the fourth quarter of 2005.

As previously announced, on March 30, 2006 Suntron entered into a new $50.0 million credit agreement that matures in March 2009, and a $10.0 million secured subordinated note purchase agreement with an affiliate of Suntron's majority stockholder. On March 30, 2006, Suntron also sold a building and land in Sugar Land, Texas, which generated net proceeds of approximately $16.5 million that was used to repay outstanding debt. Suntron leased back approximately 50% of the building under a seven-year lease.

Due to the repayment of Suntron's previous credit facility, a non-cash charge to interest expense of $1.4 million was incurred in the first quarter of 2006 for the write-off of unamortized debt issuance costs associated with the previous credit agreement. In addition to this $1.4 million charge, results for the first quarter of 2006 include restructuring costs of $0.2 million and stock compensation expense of $0.2 million. Suntron reported a net loss for the first quarter of 2006 of $1.1 million (a loss per share of $0.04), compared to net income of $0.1 million for the fourth quarter of 2005 (breakeven earnings per share), and a net loss of $6.2 million (a loss per share of $0.23) in the first quarter of 2005. Excluding the aforementioned charges, non-GAAP net income for the first quarter of 2006 was $0.7 million, or $0.03 per share.

"During 2005, we took cost reduction actions and achieved positive operating earnings for the fourth quarter on essentially a flat revenue base," stated Paul Singh, Suntron's president and chief executive officer. "With the first quarter results, we have now had four consecutive quarters of improved operating performance and two consecutive quarters of positive operating income," added Mr. Singh.

"In 2006, our goal is to further improve the utilization of our assets and right-size our U.S. footprint, continued Mr. Singh. "In the first quarter of 2006, we completed the sale of our largest facility, located in Sugar Land, Texas, and leased back half of the space. This transaction along with our refinancing improved our balance sheet by reducing overall company debt while enhancing our borrowing availability to support future growth. We continue to evaluate additional actions we need to take in 2006 to further improve our financial performance," added Mr. Singh.

"As we look ahead to the second quarter of 2006, we expect net sales to be in the range of $83 million to $86 million," continued Mr. Singh. "We are continuing to invest in our sales and marketing efforts, and we have already begun to see benefits as evidenced by the addition of six new customers in the first quarter. In addition, our management team remains focused on improving operating performance and exceeding customer expectations," concluded Mr. Singh.

Non-GAAP Information
In addition to disclosing results determined in accordance with generally accepted accounting principles (GAAP), Suntron also discloses certain non-GAAP results of operations that exclude certain items. These non-GAAP financial data are provided to facilitate meaningful period-to-period comparisons of underlying operational performance by eliminating infrequent or unusual charges. The primary measure of our operating performance is net income (loss). However, the Company's lenders, internal management and many investment analysts believe that other measures provide additional information to further analyze the company's financial performance. Additionally, in evaluating alternative measures of operating performance, it is important to understand that there are no standards for these calculations. Accordingly, the lack of standards can result in subjective determinations by management about which items may be excluded from the calculations, as well as the potential for inconsistencies between different companies that have similarly titled alternative measures. See the tables to this press release for a reconciliation of GAAP amounts to non-GAAP amounts.
