Ducommun Incorporated

Pro Forma Financial Information

(Unaudited)

The following unaudited pro forma financial statements reflect the acquisition by Ducommun on January 6, 2006, for $50,000,000 (including assumed indebtedness) plus contingent payments not to exceed $3,000,000. The purchase price is subject to adjustment based on a closing balance sheet and certain tax refunds. The acquisition was accounted for under the purchase method of accounting.

The unaudited pro forma condensed combined balance sheet at December 31, 2005 gives effect to the acquisition of Miltec assuming the transaction was consummated as of December 31, 2005. The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2005 for Ducommun and the year ended September 30, 2005 for Miltec gives effect to the acquisition of Miltec assuming the transaction was consummated as of the beginning of the period presented. The unaudited pro forma condensed combined statement of operations combined the historical statement of operations of Ducommun and Miltec for the year ended December 31, 2005 for Ducommun and September 30, 2005 for Miltec.

The Miltec acquisition will be accounted for using the purchase method of accounting. The purchase price will be allocated to acquired assets and liabilities based on their estimated fair values at the date of acquisition, and any excess is allocated to goodwill. The amount and allocation of the purchase price is subject to revision, which is not expected to be material, based on the final determination of the tangible net book value of Miltec on the closing date and the fair value of certain acquired assets and liabilities. The Miltec acquisition will be included in the Ducommun Incorporated Form 10-Q for the period ended April 1, 2006.

The unaudited pro forma condensed combined statements of operations are not necessarily indicative of the operating results that would have been achieved had the acquisition been consummated at the beginning of the periods presented and should not be construed as representative of future operating results. The pro forma financial statements should also be read in conjunction with Ducommun’s consolidated financial statements and notes set forth in the Report on Form 10-K for the year ended December 31, 2005.
