VIASYSTEMS ANNOUNCES FIRST QUARTER 2012 RESULTS

ST. LOUIS, May 9, 2012 – Viasystems Group, Inc. (NASDAQ:VIAS), a leading provider of complex multi-layer printed circuit boards and electro-mechanical solutions, today announced results for the first quarter ended March 31, 2012.

Highlights

“As I noted in my preliminary comments last month, I am encouraged by our solid start to the new year,” stated David M. Sindelar, Chief Executive Officer. “Excluding the first-quarter expense effects of special items including acquisitions and factory consolidations, we generated year-over-year growth both in net sales and in earnings. Strong overall bookings in our first quarter have us positioned for sequential and year-over-year net sales growth in the coming quarter as well.”

“I am very excited about the prospects of expanding the scope of our product and service offerings to U.S. and global customers through the combination of DDi Corp.’s business with ours,” continued Sindelar. “And, the added benefit of locking in a complementary long-term debt structure, at an historically low rate, makes the combination even more attractive to all of our stakeholders. Annual interest expense savings from re-financing our previous senior secured notes should be approximately $8.3 million, and even before considering cost synergies, DDi’s adjusted net income in 2011 would have exceeded by approximately $1.0 million the interest cost of the funds we have borrowed to finance the acquisition.”

Financial Results

The company reported net sales of $262.1 million for the three months ended March 31, 2012, a 9.8% year-over-year increase compared with net sales during the first quarter of 2011. Year-over-year increases in net sales to the company’s automotive, industrial & instrumentation, computer and datacommunications, and military and aerospace end market customers were partially offset by declines in net sales to telecommunications end market customers. Compared with the three months ended December 31, 2011, net sales declined by 2.6% for the quarter ended March 31, 2012. Sequentially, net sales increased in both industrial & instrumentation, and military and aerospace end markets, but declined in automotive, telecommunications, and computer and datacommunications end markets.

Cost of goods sold (excluding items shown separately in the income statement) as a percent of net sales improved to 80.5% for the quarter ended March 31, 2012, compared to 80.9% in the corresponding quarter a year ago. As compared to the immediately preceding quarter ended December 31, 2011, cost of goods sold increased as a percentage of net sales as a result of i) seasonal costs associated with the Chinese New Year holiday period and ii) a reduction of premium pricing opportunities experienced in the final quarter of 2011 related to PCB supply disruption in Thailand.

Operating income was $5.2 million or 2.0% of net sales for the three months ended March 31, 2012, compared with $11.2 million or 4.7% of net sales for the first quarter of 2011, and compared with $23.1 million or 8.6% of net sales for the three months ended December 31, 2011. Compared to the first quarter of 2011, increases in sales and gross profit margin were more than offset by expense increases for restructuring, depreciation and amortization, acquisitions and equity registrations, and cash and non-cash incentive compensation. Compared to the immediately preceding three months ended December 31, 2011, the decline in operating income resulted from the combination of seasonal decline in net sales and gross profit margin, reduced premium pricing opportunities, increased restructuring costs, and increased costs related to acquisitions and equity registrations.

Adjusted EBITDA, on a non-GAAP basis, was $33.1 million or 12.6% of net sales for the three months ended March 31, 2012, compared with $29.3 million or 12.3% of net sales for the first quarter of 2011, and compared with $44.1 million or 16.4% of net sales for the three months ended December 31, 2011. A reconciliation of operating income to Adjusted EBITDA is provided at the end of this news release.

For the three months ended March 31, 2012, net loss was $(5.1) million, of which $(4.6) million was attributable to common stockholders, and resulted in $(0.23) of loss per basic and diluted share. Adjusted EPS, on a non-GAAP basis, for the three months ended March 31, 2012 was $0.32. A reconciliation of GAAP diluted earnings per share to Adjusted EPS is provided at the end of this news release.

Segment Information

Net sales and operating income in the company’s Printed Circuit Boards segment for the first quarter of 2012 were $213.1 million and $7.0 million, respectively, compared with Printed Circuit Boards segment net sales and operating income of $192.7 million and $10.0 million, respectively, for the first quarter of 2011 and compared with Printed Circuit Boards segment net sales and operating income of $224.0 million and $22.3 million, respectively, for the quarter ended December 31, 2011. Approximately $6.4 million of the reported $7.0 million restructuring costs for the quarter ended March 31, 2012 were related to the previously announced closure of the company’s Huizhou, China printed circuit board manufacturing facility. Compared to the first quarter of 2011, increased net sales of printed circuit boards to customers in the automotive, computer and datacommunications, and military and aerospace end markets were partly offset by decreases in net sales to telecommunications customers and industrial & instrumentation customers. Compared to the immediately preceding three months ended December 31, 2011, an increase in net sales of printed circuit boards to customers in the military and aerospace end market was more than offset by decreases in each of the company’s other end markets, which reflected seasonal declines as well as reduced quantities of premium-priced products.

Net sales and operating loss in the company’s Assembly segment for the first quarter were $49.0 million and $(0.8) million, respectively, compared with Assembly segment net sales and operating income of $46.0 million and $1.5 million, respectively, for the first quarter of 2011 and compared with Assembly segment net sales and operating income of $45.0 million and $1.6 million, respectively, for the quarter ended December 31, 2011. Approximately $0.6 million of the reported $7.0 million restructuring costs for the quarter ended March 31, 2012 were related to the previously announced closure of the company’s Qingdao, China electro-mechanical solutions assembly facility. Compared to the first quarter of 2011, Assembly segment net sales increased in all end markets with the exception of telecommunications. Compared to the immediately preceding three months ended December 31, 2011, increased Assembly segment net sales to customers in the telecommunications and the industrial & instrumentation end markets were partly offset by decreases in the automotive and the computer and datacommunications end markets.

Cash and Working Capital

Cash and cash equivalents at March 31, 2012, were $57.8 million, compared with $80.4 million at March 31, 2011, and compared with $71.3 million at December 31, 2011. Cash provided by operating activities was $10.3 million during the quarter ended March 31, 2012, compared to cash provided by operating activities of $0.9 million for the quarter ended March 31, 2011. The company’s cash cycle metric of 32.0 days at the end of March 31, 2012 was slightly above the average for that metric during the year ended December 31, 2011, primarily related to a reduction of accounts payable.

Capital expenditures during the three months ended March 31, 2012 were $22.4 million, compared to capital expenditures of $24.0 million during the quarter ended March 31, 2011, and compared to capital expenditures of $26.5 million during the three months ended December 31, 2011. During the quarter ended March 31, 2012, approximately $9.1 million of capital expenditures were incurred in connection with capacity expansion, relocation of facilities and other special projects. In addition, during the quarter ended March 31, 2012, the company paid a deposit of $1.1 million against the agreed-upon $10.0 million purchase price for the remaining noncontrolling interest in the company’s joint venture company in Huizhou, China.

On April 30, 2012, a wholly-owned subsidiary of the company completed the private sale of $550.0 million principal amount of 7.875% senior secured notes due 2019 (“2019 Notes”). Proceeds of the 2019 Notes will be used i) to redeem all of the company’s currently outstanding $220.0 million principal amount of 12.0% senior secured notes due 2015 (“2015 Notes”), together with early termination premiums and accrued interest thereon, and ii) to fund the previously announced acquisition of DDi Corp., which is expected to be completed during the quarter ending June 30, 2012, together with related fees and expenses, and iii) to fund fees and expenses of the offering of the 2019 Notes. Interest on the 2019 Notes will be payable semi-annually in May and November, beginning November 2012. Cash used for payment of interest during the quarter ended March 31, 2012 was $13.4 million, including the semi-annual $13.2 million interest payment in January 2012 related to the 2015 Notes. Cash used for payment of income taxes during the quarter ended March 31, 2012 was $5.6 million. Cash used for payment of interest and income taxes during the quarter ended March 31, 2011 was $13.4 million and $2.8 million, respectively.

Use of Non-GAAP Financial Measures

In addition to the condensed consolidated financial statements presented in accordance with U.S. GAAP, management uses certain non-GAAP financial measures, including “Adjusted EBITDA” and “Adjusted EPS”.

Adjusted EBITDA is not a recognized financial measure under U.S. GAAP, and does not purport to be an alternative to operating income or an indicator of operating performance. Adjusted EBITDA is presented to enhance an understanding of operating results and is not intended to represent cash flows or results of operations. The Board of Directors, lenders and management use Adjusted EBITDA primarily as an additional measure of operating performance for matters including executive compensation and competitor comparisons. The use of this non-GAAP measure provides an indication of the company’s ability to service debt, and management considers it an appropriate measure to use because of the company’s leveraged position.

Adjusted EBITDA has certain material limitations, primarily due to the exclusion of certain amounts that are material to the company’s consolidated results of operations, such as interest expense, income tax expense, and depreciation and amortization. In addition, Adjusted EBITDA may differ from the Adjusted EBITDA calculations reported by other companies in the industry, limiting its usefulness as a comparative measure.

The company uses Adjusted EBITDA to provide meaningful supplemental information regarding operating performance and profitability by excluding from EBITDA certain items that the company believes are not indicative of its ongoing operating results or will not impact future operating cash flows, which include restructuring and impairment charges, loss on early extinguishment of debt, stock compensation, costs associated with acquisitions and equity registrations, and other, net.

Adjusted EPS is not a recognized financial measure under U.S. GAAP, does not purport to be an indicator of the company’s financial performance, and might not be consistent with measures used by other companies. The company’s management believes this supplemental measure is useful in understanding underlying trends of the business and analyzing the effects of certain events that are infrequent or unusual for the company.

Adjusted EPS has certain material limitations, primarily due to the exclusion of certain amounts from earnings that are material to the company’s consolidated results of operations, such as costs associated with acquisitions and equity registrations, restructuring and impairment charges, certain interest and other expenses, and certain adjustments to net income to arrive at net income available to common stockholders. As a result, Adjusted EPS differs materially from the earnings per share calculations reported by other companies in the industry, limiting its usefulness as a comparative measure.
