(b) Pro Forma Financial Information The unaudited pro forma combined condensed balance sheet and statement of operations included as Exhibit 99.4 are presented for illustrative purposes only and are not necessarily indicative of the combined financial position or results of operations for future periods or the results that actually would have been realized had Advanced Energy Industries, Inc. and its consolidated subsidiaries and Aera been a combined company as of December 31, 2001 and during the specified periods. The pro forma statements, including the notes thereto, are qualified in their entirety by reference to, and should be read together with, the historical consolidated financial statements of Advanced Energy included in Advanced Energy's Form 10-K for the year ended December 31, 2001, and together with the historical consolidated financial statements of Aera, included elsewhere in this Form 8-K/A. The following pro forma statements give effect to the acquisition of Aera using the purchase method of accounting. The purchase price (cash paid and liabilities assumed) was allocated based upon the estimated fair value of assets acquired. The preliminary purchase price allocation is based on Advanced Energy's estimates of fair value, and is subject to change based upon final determination and appraisal of fair values. Accordingly, the accompanying pro forma financial statements do not reflect the actual liabilities assumed and goodwill or other intangible assets that will result from the transaction. The unaudited pro forma combined condensed balance sheet assumes that the business combination took place on December 31, 2001, and combined Aera's unaudited condensed consolidated balance sheet as of December 31, 2001 with Advanced Energy's audited condensed consolidated balance sheet as of December 31, 2001. The unaudited pro forma combined condensed statement of operations assumes the business combination took place as of January 1, 2001, and combined Aera's unaudited condensed consolidated statement of operations for the twelve-month period ended December 31, 2001 with Advanced Energy's audited condensed consolidated statement of operations for the twelve-month period ended December 31, 2001.
