VIASYSTEMS ESTIMATES FIRST QUARTER NET SALES AND OPERATING INCOME

ST. LOUIS, April 16, 2012 – Viasystems Group, Inc. (NASDAQ:VIAS), a leading provider of complex multi-layer printed circuit boards and electro-mechanical solutions, today announced estimates of the company’s first quarter sales and operating income. The company also announced plans for an upcoming presentation to investors.

Highlights

“We are off to a good start in 2012,” stated Chief Executive Officer David M. Sindelar. “Compared to the first quarter of 2011, we achieved double-digit sales growth in our automotive and our computer and datacommunications end markets, while we saw more modest single-digit increases in our industrial & instrumentation and our military and aerospace end markets. Net sales to our telecommunications customers declined, as we expected. Compared to the fourth quarter of 2011, a combination of factors led to a slight 3% decline in our net sales, including fewer opportunities for premium pricing of our printed circuit boards, together with the seasonal effects of factory shut-downs during the Chinese New Year holiday period in mid-January.”

The estimated results in this release are preliminary and subject to completion and review of our full first quarter financial statements by our independent registered public accounting firm in conjunction with our 2012 first quarter Form 10-Q filing.

Use of Non-GAAP Financial Measures

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 of the company 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 its 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.
