IRVINE, Calif., August 12, 2024 – AEON Biopharma, Inc. (“AEON” or the “Company”) (NYSE: AEON), a clinical-stage biopharmaceutical company focused on developing a botulinum toxin complex for the treatment of multiple therapeutic indications, announced financial results for the second quarter ended June 30, 2024, and provided a business update.

“We are excited by the significant opportunity to advance our development of ABP-450 under the planned biosimilar strategy. Once we host and receive the minutes from our FDA meeting, which is being held later this quarter, we expect to have a clear path forward to initiate a single pivotal study directly comparing ABP-450 to BOTOX in the treatment of CD,” commented Marc Forth, AEON’s President and Chief Executive Officer. “The biosimilar approach may offer a potential regulatory pathway for us to bring ABP-450 differentiated economic model to the U.S. market for all of BOTOX’s currently approved and future therapeutic indications under a single approval.”

Recent Clinical and Corporate Highlights

●Development plan for ABP-450 utilizing 351(k) regulatory pathway for biosimilars - announced plans to initiate, subject to securing funding, a single pivotal clinical development study in cervical dystonia (“CD”) for the Company’s lead candidate, ABP-450 (prabotulinumtoxinA), utilizing the 351(k) regulatory pathway for biosimilars with the market leader, BOTOX® (onabotulinumtoxinA), as the reference product.

oSubmitted a briefing package to the FDA that provided extensive data from analytical, pharmacological, and animal studies that could contribute to a Biologics License Application (“BLA”) filing.

oScheduled to hold a biosimilar initial advisory meeting with FDA in 3Q 2024.

oExpect to initiate a planned Phase 3 CD study in approximately 400 patients to compare ABP-450 to BOTOX with a goal to demonstrate non-inferiority to BOTOX.

oA successful Phase 3 comparative study in CD could potentially provide the necessary clinical data to support a determination that ABP-450 is highly similar to Botox for all currently approved and future therapeutic indications.

The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The condensed 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 three and six months ended June 30, 2023, and Successor periods for the three and six months ended June 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.
