Corporate Presentation October 2023
2 Forward Looking Statements This presentation includes forward - looking statements . 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, 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 our actual results, performance or achievements 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 . We have based these forward - looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our 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 legal proceedings that may be instituted against AEON or others following the announcement of the business combination and any definitive agreements with respect thereto ; (ii) the ability to meet continued stock exchange listing standards following the consummation of the business combination ; (iii) the risk that the business combination disrupts current plans and operations of AEON as a result of the announcement and consummation of the business combination ; (iv) the ability to recognize the anticipated benefits of the business combination, which may be affected by, among other things, competition, the ability of AEON to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees ; (v) costs related to the business combination and being a public company ; (vi) changes in applicable laws or regulations ; ( vii) the possibility that AEON may be adversely affected by other economic, business, regulatory, and/or competitive factors ; (viii) AEON’s estimates of expenses and profitability ; (ix) the evolution of the markets in which AEON competes ; (x) the ability of AEON to implement its strategic initiatives, including the continued development of ABP - 450 ; (xi) the ability of AEON to defend its intellectual property ; (xii) the ability of AEON to satisfy regulatory requirements ; (xiii) the impact of adverse geopolitical and macroeconomic developments, such as the COVID - 19 pandemic, the Israel - Hamas conflict, the Ukraine - Russia conflict and related sanctions, actual and anticipated changes in interest rates, economic inflation and the responses by central banking authorities to control such inflation on AEON’s business ; (xiv) AEON’s expected capital resources and liquidity needs ; and (xv) other risks and uncertainties set forth in the section entitled "Risk Factors" and "Cautionary Note Regarding Forward - Looking Statements" in the company’s final proxy statement/prospectus relating to the business combination . 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 our control, you should not rely on these forward - looking statements as predictions of future events . The events and circumstances reflected in our forward - looking statements may not be achieved or occur, and actual results could differ materially from those projected in the forward - looking statements . Moreover, we operate 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 we assess the impact of all factors on our 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 we may make in this presentation . As a result of these factors, although we believe that the expectations reflected in our forward - looking statements are reasonable, we cannot assure you that the forward - looking statements in this presentation will prove to be accurate . Except as required by applicable law, we do 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 . We qualify all of our 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 .
3 Investment Highlights Botulinum toxin has demonstrated utility across dozens of published uses expected to be accessible to ABP - 450; accelerated and simplified commercialization timeline due to existing aesthetic BLA (separately held by Evolus) and manufacturing site approved by FDA, EMA and Health Canada Episodic migraine approval would nearly triple the current addressable patient population (Botox ® indicated for chronic migraine only); ABP - 450 Phase 2 migraine study includes chronic and episodic migraine patients with a streamlined injection protocol with potential to enhance safety and tolerability Potential to pursue traditional pharma pricing model currently not pursued by therapeutic toxin competition with a 900 kDa botulinum toxin expected to facilitate physician adoption Significant neurotoxin commercial and clinical development experience among management team translating to approximately $162M invested in AEON since 2019 Strong Potential Episodic Migraine Market Expansion Business Model Advantage Strong Leadership & Sponsorship Market Ripe for Competition Single existing competitor for key target markets (episodic & chronic migraine); unlike in aesthetic market, ABP - 450’s therapeutic focus will compete with market leader on a product - to - product basis, not against a portfolio of products PTSD Opportunity Ongoing pre - clinical program utilizing proprietary injection paradigm in a novel part of the anatomy is designed to provide IND supporting safety and efficacy data; this innovative approach has the potential for utility across a broad Neuro/Psych portfolio including PTSD

Posttraumatic Stress Disorder (PTSD)
23 Posttraumatic Stress Disorder (PTSD) • PTSD is well defined with broad disease awareness • A psychiatric disorder that may occur in people who experience or witness a traumatic event or events • Categories of symptoms include intrusion (involuntary memories), avoidance, alterations in cognition and mood (negative thoughts and feelings), and alterations in arousal and reactivity (angry outbursts) The Disorder 1 • Current t reatments include cognitive behavioral therapy, medication (e.g., SSRIs, SNRIs), and other alternative therapies • Established FDA regulatory pathway for clinical development with several medications approved for use, including Zoloft and Paxil • Numerous validated scales are already widely accepted (e.g., CAPS, PCL - 5, BDI) Current Treatments & Regulatory Pathway 1.

Effect of Stellate Ganglion Block Treatment on Posttraumatic Stress Disorder Symptoms A Randomized Clinical Trial Kristine L. Rae Olmsted, MSPH; Michael Bartoszek, MD; Sean Mulvaney, MD; et al JAMA Psychiatry. 2020;77(2):130 - 138. Key Points Question : How does stellate ganglion block compare with sham treatment in reducing the severity of posttraumatic stress disorder symptoms over 8 weeks? Findings : In this sham - controlled randomized clinical trial, 2 stellate ganglion block treatments 2 weeks apart were effective in reducing Clinician - Administered PTSD Scale for DSM - 5 total symptom severity scores over 8 weeks . The adjusted mean symptom change was − 12 . 6 points for the group receiving stellate ganglion blocks, compared with − 6 . 1 points for those receiving sham treatment, a significant difference . Meaning : Stellate ganglion block treatment warrants further study as a posttraumatic stress disorder treatment adjunct . A Sobering Look at Treatment Effectiveness of Military - Related Posttraumatic Stress Disorder A Randomized Clinical Trial Ofir Levi, Ariel Ben Yehuda, Yair Bar - Haim; et al Clinical Psychological Science. 2021; 10 , no.4 Abstract Approximately two thirds of veterans with posttraumatic stress disorder (PTSD) remain with the disorder following treatment . Pinpointing the per - symptom effectiveness of treatments in real - world clinical settings can highlight relevant domains for treatment augmentation and development . Baseline and posttreatment assessments of PTSD and depression were performed in 709 veterans with PTSD . PTSD remission was 39 . 4 % . Treatment was least effective for intrusion symptoms and had no effect on flashbacks or on poor recall of traumatic features . Of veterans who remitted, 72 . 8 % still met diagnostic criteria for at least one cluster . Poor clinical effectiveness was noted for depression ; only 4 . 1 % of the patients remitted following treatment . Treatments for veterans with PTSD show limited overall effectiveness in real - world settings . Enhancing treatment response may require enhancing provider fidelity and patient compliance with extant treatments or the development of new treatments that specifically target the symptoms of PTSD that do not respond well to extant treatments .

Please refer to “ Forward - Looking Statements” in th e slide titled "Disclaimer" for important information you should consider regarding the timing of earn - out milestone achievement, as no assurance can be given that any such indicated earn - out milestone will be achieved on the timeline indicated or at all. 1. If BLA acceptance for episodic migraine occurs prior to BLA acceptance for chronic migraine, earnout for episodic migraine BL A a cceptance will increase from 4M shares to 11M shares and there shall be no further earnout issuance for chronic migraine. In the event that AEON licenses any of its products (except for Migraine or CD indications) to a third - party licensor for distribution in the U.S. market prior to the time that the 11M shares have been issued upon achievement of either the BLA acceptance for episodic migraine or chronic migraine (as described above), then 2M shares shall be issued upon the entry int o such license agreement and the remaining shares to be issued for achievement of the BLA acceptance for episodic migraine or chronic migraine, as applicable, will be correspondingly reduced. 2. 1.45M founder shares shall vest upon the earlier to occur of (i) BLA acceptance for chronic migraine or (ii) BLA acceptance f or episodic migraine, subject to potential forfeiture of sponsor shares pursuant to the Business Combination Agreement. 7M shares - upon BLA acceptance for CM prior to 06/30/28 4M shares 1 - upon BLA acceptance for EM prior to 06/30/29 1.45M shares – upon earlier of: 1) BLA acceptance for CM prior to 06/30/28 or 2) BLA acceptance for EM prior to 06/30/29 2 5M shares - upon BLA acceptance for CD prior to 11/30/26
33 Investment Highlights Botulinum toxin has demonstrated utility across dozens of published uses expected to be accessible to ABP - 450; accelerated and simplified commercialization timeline due to existing aesthetic BLA (separately held by Evolus) and manufacturing site approved by FDA, EMA and Health Canada Episodic migraine approval would nearly triple the current addressable patient population (Botox ® indicated for chronic migraine only); ABP - 450 Phase 2 migraine study includes chronic and episodic migraine patients with a streamlined injection protocol with potential to enhance safety and tolerability Potential to pursue traditional pharma pricing model currently not pursued by therapeutic toxin competition with a 900 kDa botulinum toxin expected to facilitate physician adoption Significant neurotoxin commercial and clinical development experience among management team translating to approximately $162M invested in AEON since 2019 Strong Potential Episodic Migraine Market Expansion Business Model Advantage Strong Leadership & Sponsorship Market Ripe for Competition Single existing competitor for key target markets (episodic & chronic migraine); unlike in aesthetic market, ABP - 450’s therapeutic focus will compete with market leader on a product - to - product basis, not against a portfolio of products PTSD Opportunity Ongoing pre - clinical program utilizing proprietary injection paradigm in a novel part of the anatomy is designed to provide IND supporting safety and efficacy data; this innovative approach has the potential for utility across a broad Neuro/Psych portfolio including PTSD
