1. Basis of Presentation

The Merix Acquisition

     On February 16, 2010, Viasystems Group, Inc. (“Viasystems”) acquired Merix Corporation (“Merix”) in a transaction pursuant to which Merix became a wholly owned subsidiary of Viasystems (the “Merix Acquisition”). Merix was a leading manufacturer of technologically advanced, multi-layer printed circuit boards with operations in the United States and China. The total consideration paid by Viasystems in the merger was $111,203, and included cash of $35,326 and 3,877,304 shares of newly issued common stock of Viasystems representing approximately 19.4% of Viasystems’ common stock immediately following the Merix Acquisition. The Merix Acquisition was accounted for using the acquisition method of accounting.

The Recapitalization

     In connection with the Merix Acquisition, Viasystems undertook a recapitalization which, among a number of other related transactions, included the conversion of all outstanding shares of its preferred stock to newly issued common stock of Viasystems (the “Recapitalization”).

Accounting Periods

     The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2010, combines Viasystems’ audited consolidated statement of operations for the year ended December 31, 2010, and Merix’ historical unaudited condensed consolidated statement of operations for the period from January 1, 2010, through February 16, 2010.

Earnings Per Share

     The weighted average number of shares used to calculate basic and diluted earnings per share for the unaudited pro forma combined results for the year ended December 31, 2010, assumes that the Merix Acquisition and Recapitalization occurred on January 1, 2010. The weighted average number of shares used to calculate diluted earnings per share for the unaudited pro forma combined results for the year ended December 31, 2010, reflects the weighted average dilutive effect of restricted stock awards issued during the year.

2. Pro Forma Adjustments

     Adjustments included in the column under the heading “Pro Forma Adjustments” which are necessary to reflect the Merix Acquisition and related transactions include the following:

	A.		Reflects an adjustment to cost of goods sold of $933 for the year ended December 31, 2010, to reverse the effect of a purchase accounting adjustment that increased the book value of inventory acquired from Merix to its estimated fair value, which approximated its selling price less an estimated profit from the selling effort.
	B.		Reflects the elimination of Viasystems’ merger related transaction costs for the year ended December 31, 2010, of $4,711 and Merix’ merger related transaction costs for the period from January 1, 2010 to February 16, 2010, of $3,100.
	C.		Reflects the elimination of Merix’ historical depreciation expense for the period from January 1, 2010 to February 16, 2010, of $2,439, and the recognition of depreciation expense of $1,600 for the period from January 1, 2010 to February 16, 2010, associated with the property, plant and equipment acquired from Merix.
	D.		Reflects the elimination of Merix’ historical intangible asset amortization expense of $211 for the period from January 1, 2010, through February 16, 2010, and the recognition of amortization expense of $85 for the period from January 1, 2010 to February 16, 2010, related to amortizable intangible assets acquired from Merix. Identifiable intangible assets acquired included Merix’ customer list, manufacturer sales representative network, and trade name, and were valued at $4,100, $1,700 and $390, respectively. The values of the customer list and manufacturer sales representative network are being amortized over twelve years, and the value of the trade name is being amortized over two years.
	E.		Reflects the elimination of restructuring expense related to the Merix Acquisition and the Recapitalization for the year ended December 31, 2010, including $4,561 of severance and other costs related to the integration of the Merix business, and a $4,441 fee for the cancellation of a monitoring and oversight agreement in connection with the Recapitalization.
	F.		Reflects the elimination of interest expense of $1,315 associated with Viasystems’ Mandatory Redeemable Class A Junior preferred stock (the “Class A Preferred”) for the period from January 1, 2010 to February 16, 2010. The Class A Preferred was converted into common stock of Viasystems in connection with the Merix Acquisition.

	G.		Reflects the elimination of interest expense of $343 for the period from January 1, 2010 to February 16, 2010, associated with the $68,950 principal amount of Merix’ Senior Subordinated Convertible Notes due 2013 which were cancelled in connection with the Merix Acquisition.
	H.		Reflects forgone interest income of $9 for the year ended December 31, 2010, as a result of certain cash expenditures made in connection with the Merix Acquisition and related transactions including i) the payment of $35,326 cash consideration, ii) the payment of a $4,441 fee for the cancellation of a monitoring and oversight agreement in connection with the Recapitalization and iii) the payment of $2,342 of financing fees associated with a $75,000 senior secured revolving credit facility entered into in connection with the Merix Acquisition (the “Senior Secured 2010 Credit Facility”).
	I.		Reflects the net reduction to amortization of deferred financing costs of $24 for the year ended December 31, 2010, for the i) elimination of Merix’ historical deferred financing costs amortization for the period from January 1, 2010 to February 16, 2010, and ii) addition of amortization expense associated with capitalized costs related to the Senior Secured 2010 Credit Facility.
	J.		Reflects the elimination of $125 of fees incurred during the period from January 1, 2010 to February 16, 2010, under a monitoring and oversight agreement which was terminated in connection with the Recapitalization.
	K.		Reflects the income tax effect of $490 for the year ended December 31, 2010, related to the foregoing pro forma adjustments. As a result of Viasystems’ and Merix’ existing income tax loss carry-forwards in the United States, no income tax has been provided related to the pro forma adjustments related to that jurisdiction. The $490 pro forma adjustment primarily relates to the income tax effect of pro forma adjustments affecting Viasystems’ and Merix’ subsidiaries in China.
	L.		Reflects the elimination of the accretion of Redeemable Class B Senior Convertible preferred stock (the “Class B Preferred Stock”) of $1,053 for the period from January 1, 2010 to February 16, 2010. The Class B Preferred was converted into common stock of Viasystems in connection with the Recapitalization.
	M.		Reflects the elimination of non-cash adjustments to net income of $29,717 and $105,021 for the year ended December 31, 2010, related to the conversion of Viasystems’ Mandatory Redeemable Class A Junior preferred stock and the Class B Preferred Stock, respectively, to common stock of Viasystems in connection with the Recapitalization.
	N.		Reflects an adjustment to basic and diluted weighted average shares outstanding to reflect the common stock issuance and conversions related to the Merix Acquisition and the Recapitalization as if they had occurred on January 1, 2010.
