All statements other than statements of historical facts contained in this presentation, including statements concerning possible or assumed future actions, business strategies, events or results of operations, illustrative timelines and targets for financing and any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. These statements may involve known and unknown risks, uncertainties and other important factors that may cause the actual results, performance or achievements of AEON Biopharma, Inc. ("AEON") to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. These statements may be preceded by, followed by or include the words "believes", "estimates", "expects", "projects", "forecasts", "may", "will", "should", "seeks", "plans", "scheduled", "anticipates" or "intends" or similar expressions. The forward-looking statements in this presentation are only predictions. AEON has based these forward-looking statements largely on AEON's current expectations and projections about future events and financial trends that AEON believes may affect its business, financial condition and results of operations. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by AEON and its management, are inherently uncertain. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: (i) the outcome of any meetings with any regulatory authorities, including the FDA's review of the Company's biosimilar meetings and document submissions, (ii) the outcome of any legal proceedings that may be instituted against AEON or others; (iii) AEON's future capital requirements; (iv) AEON's ability to raise financing in the future; (v) AEON's ability to continue to meet continued stock exchange listing standards; (vi) the ability of AEON to implement its strategic initiatives, including the continued development of ABP-450 and potential submission of a Biologics License Application as a biosimilar for therapeutic uses of ABP-450; (vii) the ability of AEON to satisfy regulatory requirements; (viii) the ability of AEON to defend its intellectual property or avoid infringement of existing intellectual property; (ix) the possibility that AEON may be adversely affected by other economic, business, regulatory, and/or competitive factors; and (x) other risks and uncertainties set forth in the section entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements" in AEON's Annual Report on Form 10-K for the year ended December 31, 2024 and any current or periodic reports filed with the Securities and Exchange Commission (the "SEC"), which are available on the SEC's website at www.sec.gov. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond AEON's control, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in AEON's forward-looking statements may not be achieved or occur, and actual results could differ materially from those projected in the forward-looking statements. Moreover, AEON operates in an evolving environment and a competitive industry. New risks and uncertainties may emerge from time to time, and it is not possible for management to predict all risks and uncertainties, nor can AEON assess the impact of all factors on AEON's business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements AEON may make in this presentation. As a result of these factors, although AEON believes that the expectations reflected in its forward-looking statements are reasonable, AEON cannot assure you that the forward-looking statements in this presentation will prove to be accurate. Except as required by applicable law, AEON does not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances, or otherwise. AEON qualifies all of its forward-looking statements by these cautionary statements. You should view this presentation completely and with the understanding that the actual future results, levels of activity, performance, events and circumstances of AEON may be materially different from what is expected. This presentation concerns anticipated products that are under clinical and analytical investigation, and which have not yet been approved for marketing by the FDA. These anticipated products are currently limited by Federal law to investigational use, and no representation is made as to their safety or effectiveness for the purposes for which they are being investigated. Certain information contained in this presentation relates to or is based on studies, publications, surveys and other data obtained from third-party sources and AEON's own internal estimates and research. AEON has not independently verified, and makes no representation as to the adequacy, fairness, accuracy or completeness of, any information obtained from third-party sources. In addition, all of the market data included in this presentation involves a number of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions. Finally, AEON's own internal estimates and research have not been verified by any independent source. AEON Biopharma and the AEON Biopharma logo are trademarks of AEON Biopharma, Inc.
