Ducommun Incorporated
Pro Forma Financial Information
(Unaudited)

The following unaudited pro forma financial statements reflect the acquisition by Ducommun Incorporated (“Ducommun”) on June 6, 2001 of substantially all of the assets and assumption of certain liabilities of Composite Structures, LLC (“Composite”). The purchase price for Composite was approximately $53,584,000, subject to adjustments following the closing. The acquisition will be accounted for under the purchase method of accounting.

The unaudited pro forma condensed combined balance sheet at March 31, 2001 gives effect to the acquisition of Composite assuming the transaction was consummated as of March 31, 2001. The unaudited pro forma condensed combined statements of operations for the year ended December 31, 2000 and the three months ended March 31, 2001 give effect to the acquisition of Composite assuming the transaction was consummated as of the beginning of the periods presented. The unaudited pro forma condensed combined statements of operations combine the historical statements of operations of Ducommun and Composite for the three months ended March 31, 2001 and the year ended December 31, 2000.

The Composite acquisition will be accounted for using the purchase method of accounting. The purchase price is allocated to acquired assets and liabilities based on their estimated fair values at the date of the 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 Composite on the closing date and the fair value of certain acquired assets and liabilities. The Composite acquisition was included in the Ducommun Incorporated Form 10-Q for the period ended June 30, 2001.

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, 2000 and the Form 10-Q for the quarter ended June 30, 2001.
