The consolidated financial statements include the accounts of the Company and its controlled subsidiaries. On July 21, 2023, AEON completed the Merger with AEON Biopharma Sub, Inc. (“Old AEON”), with Old AEON surviving the merger as a wholly-owned subsidiary of the Company, the accounting acquirer. The transaction has been accounted for as a forward merger asset acquisition. Unless the context otherwise requires, the “Company,” for periods prior to the close of the Merger, refers to Old AEON, currently AEON Biopharma Sub, Inc. (“Predecessor”), and for the periods after the close of the Merger, refers to AEON Biopharma, Inc., including AEON Biopharma Sub, Inc. (“Successor”). As a result of the Merger, the results of operations, financial position and cash flows of the Predecessor and Successor are not directly comparable. AEON Biopharma Sub, Inc. was deemed to be the Predecessor entity. Accordingly, the historical financial statements of AEON Biopharma Sub, Inc. became the historical financial statements of the combined Company, upon the consummation of the Merger. As a result, the financial statements included in this release reflect (i) the historical operating results of AEON Biopharma Sub, Inc. prior to the Merger and (ii) the combined results of the Company, including AEON Biopharma Sub, Inc., following the closing of the Merger. The accompanying financial statements include Predecessor periods for the period from January 1, 2023 to July 21, 2023 and July 1, 2023 to July 21, 2023, and Successor periods for the three and nine months ended September 30, 2024. A black line between the Successor and Predecessor periods has been placed in the condensed consolidated financial statements and in the tables to the notes to the condensed consolidated financial statements to highlight the lack of comparability between these periods.
