EXHIBIT 99.1 PRO FORMA FINANCIAL INFORMATION (UNAUDITED) The following Unaudited Pro Forma Condensed Combined Statement of Operations for the six months ended June 30, 2001 gives effect to the Company's March 1, 2001 acquisition (the "Acquisition") of Avis Group Holdings, Inc. ("Avis"), which has been accounted for under the purchase method of accounting. The Unaudited Pro Forma Condensed Combined Statement of Operations assumes the Acquisition occurred on January 1, 2001. The unaudited pro forma financial information is based on the historical consolidated financial statements of the Company and Avis under the assumptions and adjustments set forth in the accompanying explanatory notes. Since Avis was consolidated with the Company as of March 1, 2001, the results of operations of Avis between January 1, 2001 and February 28, 2001 were combined with the Company's results of operations to report the combined pro forma results of operations for the six month period ended June 30, 2001. All intercompany transactions were eliminated on a pro forma basis. Historically, Avis paid the Company for services the Company provided related to call centers and information technology and for the use of the Company's trademarks. As a result of the Acquisition, the Company made payments totaling approximately $994 million, including payments of $937 million to Avis stockholders, direct expenses of $40 million related to the transaction and the net cash obligation of $17 million related to Avis stock options settled prior to consummation. The purchase price also included the fair value of CD common stock options exchanged with certain fully-vested Avis stock options. The Unaudited Pro Forma Condensed Combined Statement of Operations reflects interest expense resulting from a portion of the purchase price being funded by the issuance of $600 million in debt, with the remaining amount provided by cash. The unaudited pro forma financial information excludes any benefits that might result from the Acquisition due to synergies that may be derived or from the elimination of duplicate efforts. The Company's management believes that the assumptions used provide a reasonable basis on which to present the unaudited pro forma financial information. The Company has completed other acquisitions and dispositions which are not significant and, accordingly, have not been included in the accompanying unaudited pro forma financial information. The unaudited pro forma financial information may not be indicative of the results of operations that would have occurred if the Acquisition had been in effect on the dates indicated or which might be obtained in the future. The unaudited pro forma financial information should be read in conjunction with the historical consolidated financial statements and accompanying notes for the Company and Avis. <Page> CENDANT CORPORATION AND SUBSIDIARIES UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 2001 (IN MILLIONS, EXCEPT PER SHARE AMOUNTS) <Table> <Caption> HISTORICAL HISTORICAL AVIS PURCHASE COMBINED CENDANT JAN 1- FEB 28, 2001 ADJUSTMENTS PRO FORMA ---------- ------------------- ----------- --------- REVENUES Membership and service fees, net $ 2,431 $ 27 $ (34)(a) $ 2,424 Vehicle-related 1,433 594 -- 2,027 Other 25 20 -- (b) 45 ---------- ------------------- ----------- --------- Net revenues 3,889 641 (34) 4,496 EXPENSES Operating 1,239 174 (34)(a) 1,379 Vehicle depreciation, lease charges and interest, net 725 350 -- 1,075 Selling, general and administrative 895 115 -- 1,010 Non-vehicle depreciation and amortization 222 23 2 (d) 247 Other charges, net 212 - -- 212 Non-vehicle interest, net 122 12 1 (c) 135 ---------- ------------------- ----------- --------- Total expenses 3,415 674 (31) 4,058 Net gain on dispositions of businesses 435 -- -- 435 ---------- ------------------- ----------- --------- INCOME (LOSS) BEFORE INCOME TAXES, MINORITY INTEREST AND EQUITY IN HOMESTORE.COM 909 (33) (3) 873 Provision (benefit) for income taxes 336 (10) (2)(e) 324 Minority interest, net of tax 18 -- -- 18 Losses related to equity in Homestore.com, net of tax 36 -- -- 36 ---------- ------------------- ----------- --------- INCOME (LOSS) BEFORE CUMULATIVE EFFECT OF ACCOUNTING CHANGE $ 519 $ (23) $ (1) $ 495 ========== ================= =========== ========= CD COMMON STOCK INCOME PER SHARE INCOME BEFORE CUMULATIVE EFFECT OF ACCOUNTING CHANGE Basic $ 0.61 $ 0.58 Diluted 0.58 0.55 WEIGHTED AVERAGE SHARES OUTSTANDING Basic 820 820 Diluted 868 868 MOVE.COM COMMON STOCK INCOME PER SHARE INCOME BEFORE CUMULATIVE EFFECT OF ACCOUNTING CHANGE Basic $ 9.94 $ 9.94 Diluted 9.81 9.81 WEIGHTED AVERAGE SHARES OUTSTANDING Basic 2 2 Diluted 2 2 </Table> SEE ACCOMPANYING NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS. <Page> CENDANT CORPORATION AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENT OF OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 2001 (DOLLARS IN MILLIONS) (a) Represents the elimination of amounts paid by Avis to the Company for services provided by the Company related to call centers and information technology and for the use of trademarks.
