Exhibit 99.1

Unaudited Pro Forma Condensed Consolidated Financial Information

On May 29, 2024, eBay Inc. (“eBay”) completed the sale of (1) 227,115,592 shares of Adevinta ASA (“Adevinta”) to Aurelia BidCo 1 Norway AS (“BidCo 1”) in exchange for approximately $2.4 billion in cash and (2) 177,115,591 shares of Adevinta to Aurelia Netherlands TopCo B.V. (“TopCo”) in exchange for the issuance of 177,115,591 shares in TopCo (collectively, the “Transactions”).

The following unaudited pro forma condensed consolidated financial information has been derived from the historical financial statements of eBay Inc., adjusted to give effect to the consummation of the Transactions pursuant to the Bid Conduct Agreement and the Transaction Completion Agreement, each dated as of November 21, 2023 and amended as of May 10, 2024, by and among eBay, eBay International Holding GmbH, a wholly owned subsidiary of eBay ("eBay GmbH"), eBay International Management B.V., a wholly owned subsidiary of eBay (together with eBay and eBay GmbH, the "eBay Parties"), BCP Aurelia Luxco S.à r.l., Aurelia UK Feederco Limited (the "Equity Investor"), TopCo, Aurelia BidCo Norway AS (“BidCo”) and BidCo 1. BidCo 1 is a wholly owned subsidiary of BidCo incorporated under the laws of Norway, BidCo is a wholly owned subsidiary of TopCo incorporated under the laws of Norway, and TopCo is a private limited company incorporated under the laws of the Netherlands. In connection with the Transactions, the eBay Parties also granted the Equity Investor a six-month option to purchase TopCo shares from the eBay Parties (the "Purchase Option"), which, if exercised, would reduce eBay's ownership in TopCo to approximately 8.3%. This unaudited pro forma condensed consolidated financial information should be read in conjunction with the accompanying notes and tax rate assumption as well as the historical consolidated financial statements and related notes of eBay.

The unaudited pro forma condensed consolidated financial statements as of and for the three months ended March 31, 2024 are based on eBay's historical unaudited consolidated financial statements. The unaudited pro forma consolidated statement of income for the year ended December 31, 2023 is based on eBay's historical audited consolidated financial statements. eBay's historical audited consolidated financial statements were filed on February 28, 2024 with its Annual Report on Form 10-K for the year ended December 31, 2023, and its historical unaudited financial statements as of and for the three months ended March 31, 2024 were filed on May 2, 2024 with its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2024.

The unaudited pro forma condensed consolidated statements of income for the year ended December 31, 2023 and the three months ended March 31, 2024 assume that the Transactions occurred on January 1, 2023. The unaudited pro forma condensed consolidated balance sheet as of March 31, 2024 assumes that the Transactions occurred on March 31, 2024. The unaudited pro forma condensed consolidated financial information and transaction accounting adjustments are preliminary and have been made solely for informational purposes, are not intended to be a complete presentation of eBay's financial position or results of operations had the Transactions occurred as of and for the periods presented and are not necessarily indicative of the condensed consolidated financial position or results of operations that would have been realized had the Transactions occurred as of the dates indicated, nor are they meant to be indicative of any anticipated condensed consolidated financial position or future results of operations that eBay will experience. For example, the accompanying unaudited pro forma condensed consolidated statements of income do not include the gain on disposition of Adevinta shares by eBay. The adjustments presented are based on currently available information and certain preliminary estimates and assumptions, including preliminary estimates of the fair value of the Purchase Option. Therefore, actual results may differ from the pro forma adjustments.
