Viasystems Group, Inc. (NASDAQ: VIAS), and DDi Corp. (NASDAQ: DDIC) announced today that they have entered into a definitive merger agreement pursuant to which Viasystems will acquire DDi for $13.00 per share in cash, which represents a 20% premium to the volume weighted average price of DDi's common stock over the last three months. The total transaction value is approximately $282 million, or $268 million net of DDi's cash plus debt assumed.

With this acquisition, Viasystems will combine its large, high volume footprint in China and North America with DDi's high mix, low volume footprint in North America to create a clear leader in the printed circuit board ("PCB") industry with global capabilities and scale. The transaction allows Viasystems, already a leading market player in the automotive segment, to increase its market share in the technically demanding military and aerospace market and the growing industrial & instrumentation market while broadening its customer base. In addition, the acquisition of DDi expands Viasystems' quick-turn manufacturing capability and adds flex and rigid-flex product offerings, which will provide additional sales opportunities through Viasystems' existing customer base.

DDi's customers, meanwhile, will continue to have access to state of the art, higher technology quick-turn manufacturing services and gain seamless access to a higher volume, lower cost complex PCB manufacturing source off shore.

Based on the results for the twelve months ended December 31, 2011 for Viasystems and DDi, on a pro forma basis, the combined operation would have had approximately $1,320 million of revenue, and, excluding any cost synergies, pro forma Adjusted EBITDA would have been approximately $183 million. Viasystems expects the transaction to be immediately accretive to Adjusted EPS, even without the impact of anticipated cost synergies, which Viasystems expects to be at least $10 million annually, before income tax effects, and realizable within 6 months after closing. Adjusted EBITDA and Adjusted EPS are defined below.

Following the closing of the transaction, the combined company will have approximately 15,650 employees and manufacturing floor space exceeding 4.3 million square feet in China and 1.0 million square feet in North America.

David Sindelar, Chief Executive Officer of Viasystems, said, "This transaction combines two market leaders and strengthens Viasystems' position as a world-class leader in PCB and related electro-mechanical solutions by expanding our technology and manufacturing capabilities, diversifying our end markets and broadening our customer base and product portfolio. Ultimately, this transaction creates a larger platform which Viasystems can better leverage to serve our customers and to generate attractive returns for our shareholders. Further, the addition of DDi strengthens Viasystems' financial model and enables us to achieve even higher levels of profitability and cash generation."

Mikel Williams, Chief Executive Officer of DDi, said, "We believe that this transaction is an excellent opportunity to realize value for DDi shareholders and creates new opportunities for our customers and employees. Viasystems provides the opportunity for our customers to expand with the combined company into the Asian-based high volume market while also having the ability to offer our leading quick-turn and prototyping capabilities to Viasystems' customers. Like DDi, Viasystems has an excellent reputation as a trusted provider of PCBs to customers whose products demand high reliability, and we look forward to continuing to address the ever-changing needs of the PCB industry as part of the Viasystems team."

Transaction Details

The terms of the agreement were unanimously approved by the boards of directors of both Viasystems and DDi. The acquisition is subject to customary closing conditions, including the receipt of regulatory approvals and adoption of the merger agreement by DDi shareholders, and is expected to be completed late in the second quarter or early in the third quarter of calendar 2012. All members of DDi's board of directors and certain members of management have agreed to vote a number of common shares representing approximately 23% of the outstanding shares of DDi in favor of the merger.

The transaction is not subject to a financing condition as Viasystems has received a financing commitment from Goldman Sachs Bank USA, an affiliate of Wells Fargo Securities, LLC and Stifel Financial in connection with the acquisition. Stifel Nicolaus Weisel is acting as exclusive financial advisor and Jones Day is acting as legal counsel to Viasystems. Jefferies & Company and Mooreland Partners LLC are acting as financial advisors and Paul Hastings LLP is acting as legal counsel to DDi. Jefferies & Company has also provided a Fairness Opinion to the board of directors of DDi.

Use of Non-GAAP Financial Measures

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

Adjusted EBITDA is defined as net income adjusted to exclude charges for depreciation, amortization, net interest expense, income taxes, restructuring and impairment, non cash stock compensation, costs related to acquisitions and equity registrations and other expense, net. For reconciliation of adjusted EBITDA to net income please see Appendix A to our presentation filed as Exhibit 99.2 to our Current Report on Form 8-K filed on April 4, 2012.

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.

Viasystems 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 defined as net income, adjusted to exclude restructuring and impairment, amortization, non cash interest, non cash stock compensation, costs related to acquisitions and equity registrations, special income tax items and other nonrecurring items (all of these adjustments net of tax) divided by diluted weighted shares outstanding.

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. Viasystems' 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 Viasystems' 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.
