All statements other than statements of historical facts contained in this prospectus, 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 prospectus 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 speak only as of the date of this prospectus and are subject to a number of important factors that could cause actual results to differ materially from those in the forward-looking statements, including the risks, uncertainties and assumptions described under the section in this prospectus titled “Risk Factors.” These forward-looking statements are subject to numerous risks, including, without limitation, the following:

the projected financial information, anticipated growth rate, and market opportunities of AEON;

the ability to maintain the listing of Common Stock and the Warrants on NYSE American;

AEON’s public securities’ potential liquidity and trading;

AEON’s ability to raise financing in the future;

AEON’s success in retaining or recruiting, or changes required in, officers, key employees or directors, or;

factors relating to the business, operations and financial performance of AEON, including:

AEON’s ability to identify, develop and commercialize its main product candidate, botulinum toxin complex, ABP-450 (prabotulinumtoxinA) injection, or ABP-450;

AEON’s ability to advance its current and potential future product candidates into, and successfully complete, preclinical studies and clinical trials;

AEON’s ability to obtain and maintain regulatory approval of its current and potential future product candidates, and any related restrictions, limitations and/or warnings in the label of an approved product candidate;

AEON’s ability to implement and maintain effective internal controls;

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 prospectus. 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 prospectus 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.

You should read this prospectus completely and with the understanding that our actual future results may be materially different from our expectations. We qualify all of our forward-looking statements by these cautionary statements. You should read this prospectus and the documents that have been filed as Exhibits hereto 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.

PROSPECTUS SUMMARY

This summary highlights, and is qualified in its entirety by, the more detailed information and financial statements included elsewhere in this prospectus. This summary does not contain all of the information that may be important to you in making your investment decision. You should read this entire prospectus carefully, especially the “Risk Factors” section beginning on page 8 and our consolidated financial statements and the related notes appearing at the end of this prospectus, before deciding to invest in our Common Stock or Warrants.

Overview

AEON is a clinical stage biopharmaceutical company focused on developing a proprietary botulinum toxin complex, or ABP-450, for debilitating medical conditions, with an initial focus on the neurology and gastroenterology markets. AEON plans to develop ABP-450 to address the estimated $3.0 billion global therapeutic botulinum toxin market, which is projected to grow to $4.4 billion in 2027. ABP-450 is the same botulinum toxin complex that is currently approved and marketed for cosmetic indications by Evolus, Inc. under the name Jeuveau. ABP-450 is manufactured by Daewoong (as defined in this prospectus) in compliance with current good manufacturing practices, or cGMP, in a facility that has been approved by the United States Food and Drug Administration, or the FDA, Health Canada, and the European Medicines Agency, or the EMA. AEON has exclusive development and distribution rights for therapeutic indications of ABP-450 in the United States, Canada, the European Union, the United Kingdom, and certain other international territories. AEON has built a highly experienced management team with specific experience in biopharmaceutical and botulinum toxin development and commercialization.

Botulinum toxins have proven to be a highly versatile therapeutic biologic, with over 230 therapeutic uses documented in published scientific literature and nine approved therapeutic indications in the United States. AEON’s initial development programs for ABP-450 are directed at migraine, cervical dystonia and gastroparesis. AEON selected these initial indications based on a comprehensive and proprietary product assessment screen designed to identify indications where AEON believes ABP-450 can deliver significant value to patients, physicians and payors and where its clinical, regulatory and commercial characteristics suggest viability. AEON believes that ABP-450 has application in a broad range of indications and we plan to continue to explore additional indications that satisfy AEON’s product assessment screens.

Background

We were incorporated as Priveterra Acquisition Corp. on November 17, 2020. On July 21, 2023, we closed the Business Combination with Old AEON, as a result of which Old AEON became a wholly-owned subsidiary of ours, and we changed our name to AEON Biopharma, Inc. We are the legal acquirer of Old AEON in the Business Combination, and have been deemed to be the accounting acquirer of Old AEON. Old AEON is considered a variable interest entity, or a VIE, and we will be considered the primary beneficiary as our ownership will provide the power to direct the activities that most significantly impact AEON’s performance and the obligation to absorb the losses and/or receive the benefits of AEON that could potentially be significant to AEON.

At the effective time of the Business Combination, or the Effective Time, (i) each outstanding share of Old AEON common stock (on an as-converted basis after taking into effect the conversion of the outstanding warrants of Old AEON exercisable for shares of Old AEON preferred stock, the conversion of the shares of Old AEON preferred stock into Old AEON common stock in accordance with the governing documents of Old AEON as of the Effective Time, the conversion of the outstanding convertible notes of Old AEON into Old AEON common stock in accordance with the terms of such convertible notes and after giving effect to the issuance of Old AEON common stock in connection with the merger of ABP Sub, Inc. with and into Old AEON, or the Subsidiary Merger) issued and outstanding immediately prior to the Effective Time converted into the right to receive approximately 2.328 shares of our Common Stock. In addition, each share of Priveterra Class B common stock, or the Founder Shares, par value $0.0001 per share, issued and outstanding immediately prior to the Effective Time converted into one share of Common Stock (of which 3,450,000 Founder Shares are subject to certain vesting and forfeiture conditions).

Committed Financing Agreements

On January 6, 2023, Old AEON and Priveterra entered into Committed Financing Agreements with each of Alphaeon 1 LLC (“A1”) and Daewoong Pharmaceutical Co., Ltd. (“Daewoong”, and together with A1, the “Committed Financing Investors” and such agreements, the “Original Committed Financing Agreements”), pursuant to which the Committed Financing Investors agreed to

purchase, and Priveterra and Old AEON agreed to sell to the Committed Financing Investors, $20 million aggregate principal of interim notes convertible into an aggregate of 2,857,143 shares of common stock of Priveterra, for a purchase price of $7.00 per share pursuant to the Original Committed Financing Agreements.

Pursuant to its Original Committed Financing Agreement, on March 9, 2023, A1 executed an Interim Note Subscription Agreement (the “Original A1 Note Subscription Agreement”) for the subscription of $15 million aggregate principal of interim notes issued by Old AEON. On June 23, 2023, A1 entered into an amendment to its Original A1 Note Subscription Agreement (the “Amended A1 Note Subscription Agreement”) to add the subscription of $20 million additional aggregate principal of interim notes convertible into 2,857,143 shares of Priveterra Class A Common Stock, for a purchase price of $7.00 per share pursuant to the Additional Committed Financing Agreement.

Pursuant to its Original Committed Financing Agreement, on June 27, 2023, Daewoong executed a Note Subscription Agreement (the “Daewoong Note Subscription Agreement” and together with the Amended A1 Note Subscription Agreement, the “Note Subscription Agreements”), pursuant to which Daewoong agreed to purchase, and Priveterra and Old AEON agreed to sell to Daewoong, an additional aggregate $5 million aggregate principal of interim notes convertible into 714,285 shares of Common Stock of Old AEON after the Closing, for a purchase price of $7.00 per share.

At the closing of the Business Combination, the interim notes held by A1, including interest accrued pursuant to the Original A1 Note Subscription Agreement, and Daewoong converted into an aggregate of 5,797,611 shares of Common Stock.

Forward Purchase Agreements

On June 29, 2023, Priveterra and Old AEON entered into separate agreements (each a “Forward Purchase Agreement”, and together, the “Forward Purchase Agreements”) with each of (i) ACM ARRT J LLC and (ii) Polar Multi-Strategy Master Fund (“Polar”, and each of ACM ARRT J LLC and Polar, individually, a “Seller”, and together, the “Sellers”) for OTC Equity Prepaid Forward Transactions. For purposes of each Forward Purchase Agreement, Priveterra is referred to as the “Counterparty” prior to the consummation of the Business Combination, while AEON is referred to as the “Counterparty” after the consummation of the Business Combination. Capitalized terms used herein but not otherwise defined shall have the meanings ascribed to such terms in the Forward Purchase Agreements.

Pursuant to the terms of the Forward Purchase Agreements, the Sellers intend, but are not obligated, to purchase up to 7,500,000 shares of Priveterra Class A Common Stock in the aggregate concurrently with the Closing pursuant to each Seller’s respective FPA Funding Amount PIPE Subscription Agreement (as defined below), less the number of shares of Priveterra Class A Common Stock purchased by each Seller separately from third parties through a broker in the open market (the “Recycled Shares”). No Seller shall be required to purchase an amount of shares of Priveterra Class A Common Stock such that following such purchase, that Seller’s ownership would exceed 9.9% of the total shares of Priveterra Class A Common Stock outstanding immediately after giving effect to such purchase, unless such Seller, at its sole discretion, waives such 9.9% ownership limitation. The Number of Shares subject to a Forward Purchase Agreement is subject to reduction following a termination of the Forward Purchase Agreements with respect to such shares as described under “Optional Early Termination” in the respective Forward Purchase Agreements.

PIPE Subscription Agreements

On June 29, 2023, Priveterra entered into separate subscription agreements (the “FPA Funding Amount PIPE Subscription Agreements”) with each of ACM ARRT J LLC and Polar (collectively, the “FPA Funding PIPE Investors”). Pursuant to the FPA Funding Amount PIPE Subscription Agreements, the FPA Funding PIPE Investors agreed to subscribe for and purchase, and Priveterra agreed to issue and sell to the FPA Funding PIPE Investors, on the Closing, an aggregate of 7,500,000 shares of Priveterra Class A Common Stock, less the Recycled Shares in connection with the Forward Purchase Agreements.

Also on June 29, 2023, Priveterra entered into separate subscription agreements (the “New Money PIPE Subscription Agreements” and together with the FPA Funding Amount PIPE Subscription Agreements, the “PIPE Subscription Agreements”) with each of ACM ASOF VIII Secondary-C LP and Polar (each, a “New Money PIPE Investor” and collectively, the “New Money PIPE Investors”). Pursuant to the New Money PIPE Subscription Agreements, the New Money PIPE Investors agreed to subscribe for and purchase, and Priveterra agreed to issue and sell to the New Money PIPE Investors, on the Closing Date, an aggregate of 1,000,000 shares of Priveterra Class A Common Stock for a purchase price of $7.00 per share, for aggregate gross proceeds of $7 million.

Table of Contents

Pursuant to its New Money PIPE Subscription Agreement, Priveterra issued 75,000 shares of Priveterra Class A Common Stock to Midtown Madison Management LLC, an affiliate of ACM ASOF VIII Secondary-C LP, which are subject to a lock-up period of 180 calendar days immediately following the Closing, as a structuring fee in consideration of certain services provided by it in the structuring of its Forward Purchase Agreement and the transactions described therein.

Letter Agreements

On June 29, 2023, Priveterra Sponsor, LLC (“Sponsor”) entered into separate letter agreements (each, a “Letter Agreement” and collectively, the “Letter Agreements”) with each of ACM ASOF VIII Secondary-C LP and Polar. Capitalized terms used herein but not otherwise defined shall have the meanings ascribed to such terms in the Letter Agreements.

Pursuant to the Letter Agreements, in the event that the Transfer VWAP (as defined in the Letter Agreements) for the shares of Priveterra Class A Common Stock purchased pursuant to the New Money PIPE Subscription Agreements that are Transferred during the Measurement Period (the “Transferred PIPE Shares”) is less than $7.00 per share, then (i) ACM ASOF VIII Secondary-C LP and Polar shall be entitled to receive a number of additional shares of Priveterra Class A Common Stock that have been registered for resale by the Company under an effective resale registration statement pursuant to the Securities Act, under which ACM ASOF VIII Secondary-C LP and Polar may sell or transfer such shares of Priveterra Class A Common Stock in an amount that is equal to the lesser of (A) a number of shares of Priveterra Class A Common Stock equal to the Make-Whole Amount divided by the VWAP (measured as of the date the Additional Shares are Transferred to ACM ASOF VIII Secondary-C LP or Polar, as applicable) and (B) 400,000 shares of Priveterra Class A Common Stock (the “Additional Shares”) and (ii) Sponsor shall promptly (but in any event within fifteen (15) business days) after the Measurement Date, transfer the Additional Shares to ACM ASOF VIII Secondary-C LP or Polar, as applicable. For the avoidance of doubt, in the event the Transfer VWAP for the Transferred PIPE Shares is equal to or more than $7.00 per share, then neither ACM ASOF VIII Secondary-C LP nor Polar shall be entitled to any Additional Shares. “Make-Whole Amount” means an amount equal to the product of (A) $7.00 minus the Transfer VWAP multiplied by (B) the number of Transferred PIPE Shares.

Additional PIPE Subscription Agreements

On June 28, 2023, Priveterra entered into 10 separate subscription agreements (the “Round Lot Holder Subscription Agreements” and, together with the PIPE Subscription Agreements, the “PIPE Investments”) with certain counterparties, each for the subscription of 100 shares of Priveterra Class A common stock at a purchase price of $7.00 per share, for an aggregate purchase price of $7,000.

Lock-Up Restrictions

We amended our bylaws in connection with the Business Combination to, among other things, provide that, subject to certain exceptions, each of the stockholders of Old AEON immediately prior to the Business Combination and the former directors, officers and employees of Old AEON as of the Closing that had restricted stock units, stock options or other equity awards outstanding as of immediately following the Closing (collectively, the “Lock-up Holders”) may not sell, assign, or transfer any shares (the “Lock-up”) of Common Stock issued to such Lock-up Holders as consideration in the Business Combination (the “Lock-up Shares”), subject to certain permitted transfers, until the earliest of (i) the one year anniversary of the Closing and (ii) the date upon which there occurs the completion of a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the public stockholders of AEON having the right to exchange their Common Stock for cash, securities or other property, except that (i) 50% of such shares held by certain stockholders of Old AEON that entered into support agreements with Old AEON (“Old AEON Supporting Stockholders”) are subject to early release from the Lock-up if the volume weighted average price of Common Stock exceeds $12.50 for 20 trading days within any 30-trading day period beginning 150 days following the Closing Date, and (ii) the remaining 50% of such shares held by the Old AEON Supporting Stockholders are subject to early release from the Lock-up if the volume weighted average price of Common Stock exceeds $15.00 for 20 trading days within any 30-trading day period beginning 150 days following the Closing Date. In addition, concurrently with the execution of the Business Combination Agreement, the Sponsor and certain Priveterra insiders party thereto entered into a sponsor agreement, or the Sponsor Agreement, pursuant to which fifty percent (50)% of the 6,900,000 Founder Shares, or the contingent founder shares, are subjected to certain time and performance-based vesting provisions.

We may take advantage of these provisions until the last day of our fiscal year following the fifth anniversary of the completion of Priveterra’s initial public offering. However, if (i) our annual gross revenue exceeds $1.235 billion, (ii) we issue more than $1.0 billion of non-convertible debt in any three-year period or (iii) we become a “large accelerated filer” (as defined in Rule 12b-2 under the Exchange Act of 1934, as amended, or the Exchange Act) prior to the end of such five-year period, we will cease to be an emerging growth company. We will be deemed to be a “large accelerated filer” at such time that we (a) have an aggregate worldwide market value of common equity securities held by non-affiliates of $700.0 million or more as of the last business day of our most recently completed second fiscal quarter, (b) have been required to file annual and quarterly reports under the Exchange Act, for a period of at least 12 months and (c) have filed at least one annual report pursuant to the Exchange Act.

We have elected to take advantage of certain of the reduced disclosure obligations in the registration statement of which this prospectus is a part and may elect to take advantage of other reduced reporting requirements in future filings. As a result, the information that we provide to our stockholders may be different than you might receive from other public reporting companies in which you hold equity interests.

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. We have elected to use the extended transition period for complying with new or revised accounting standards. As a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates.

RISK FACTORS

You should carefully consider the risks and uncertainties described below and the other information in this prospectus before making an investment in our Common Stock or Warrants. Our business, financial condition, results of operations, or prospects could be materially and adversely affected if any of these risks occurs, and as a result, the market price of our Common Stock and Warrants could decline and you could lose all or part of your investment. This prospectus also contains forward-looking statements that involve risks and uncertainties. See “Cautionary Statement Regarding Forward-Looking Statements.” Our actual results could differ materially and adversely from those anticipated in these forward-looking statements as a result of certain factors, including those set forth below.

Risks Related to Our Business Operations and Financial Position

We have a limited operating history and have incurred significant losses since our inception and anticipate that we will continue to incur losses for the foreseeable future. If we ever achieve profitability, we may not be able to sustain it.

We are a clinical stage biopharmaceutical company with a limited operating history. Pharmaceutical product development is a highly speculative undertaking and involves a substantial degree of risk. Old AEON was originally incorporated in 2012 but did not begin focusing its efforts and financial resources on the clinical development and regulatory approval of ABP-450 for therapeutic indications until 2019. The operating history upon which investors must evaluate our business and prospects is limited. Consequently, any predictions about our future success, performance or viability may not be as accurate as they could be if we had a longer operating history or a history of commercial operations. In addition, as an organization, we have limited experience and have not yet demonstrated an ability to successfully overcome many of the risks and uncertainties frequently encountered by companies in the biopharmaceutical market. To date, we have not obtained any regulatory approvals for ABP-450 or generated any revenue from product sales relating to therapeutic uses of ABP-450.

Because we have not yet received regulatory approvals, we are not permitted to market ABP-450 for therapeutic use in the United States or in any other territory, and as such, we have not generated any revenue from sales of ABP-450 to date. We have recorded losses from operations of $48.4 million and $65.8 million for the years ended December 31, 2022 and 2021, respectively, and we recorded net losses of $27.0 million and $23.5 million for the six months ended June 30, 2023 and 2022, respectively. As a result of our ongoing losses, as of June 30, 2023, we had an accumulated deficit of 507.9 million. We expect to continue to incur losses for the foreseeable future, and we anticipate these losses will increase as we continue to seek regulatory approval for, and begin to commercialize, ABP-450, if approved. We may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenues. Our prior losses and expected future losses have had and will continue to have an adverse effect on our stockholders’ equity (deficit) and working capital. Because of the numerous risks and uncertainties associated with drug development, we are unable to accurately predict the timing or amount of increased expenses, or when, if at all, we will be able to achieve profitability. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our prior losses, combined with expected future losses, may adversely affect the market price of Common Stock and our ability to raise capital and continue operations.

Our management has concluded that uncertainties around our ability to raise additional capital raise substantial doubt about our ability to continue as a going concern. We will require additional financing to fund our future operations. Any failure to obtain additional capital when needed on acceptable terms, or at all, could force us to delay, limit, reduce or terminate our operations.

We have concluded that we do not have sufficient cash to fund our operations and to meet our obligations as they become due within one year from the date that our consolidated financial statements are issued and as a result, there is substantial doubt about our ability to continue as a going concern.

Our ability to continue as a going concern is an issue raised as a result of ongoing operating losses and a lack of financing commitments to meet cash requirements, and is subject to our ability to generate a profit or obtain appropriate financing from outside sources, including obtaining additional funding from the sale of our securities or obtaining loans from third parties where possible. While the Business Combination provided some capital, it is unlikely to be sufficient to remove the doubt about our ability to continue as a going concern and we will need to raise additional capital to fund our operations. We cannot assure you that we will be able to raise additional capital on commercially reasonable terms or at all. If we cannot continue as a going concern, we may have to liquidate

8

Table of Contents

our assets and may receive less than the value at which those assets are carried on our financial statements, and it is likely that our stockholders may lose some or all of their investment in us.

We expect that we will continue to expend substantial resources for the foreseeable future in order to complete development of and seek regulatory approval for ABP-450 for the treatment of migraine, cervical dystonia and gastroparesis, identify future potential therapeutic applications for ABP-450 and establish sales and marketing capabilities to commercialize ABP-450 across any approved indications.

The net proceeds from the Business Combination, along with our cash and committed financings, are sufficient to fund our operating plan through at least June 30, 2024. We have based these estimates, however, on assumptions that may prove to be wrong, and we could spend our available capital resources much faster than we currently expect or require more capital to fund our operations than we currently expect. Our future capital requirements depend on many factors, including:

If we raise additional capital through marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish certain valuable rights to our product candidate(s), technologies, future revenue streams or research programs or may have to grant licenses on terms that may not be favorable to us. If we raise additional capital through public or private equity offerings or offerings of securities convertible into our equity, the ownership interest of stockholders will be diluted and the terms of any such securities may have a preference over our Common Stock. Debt financing, receivables financing and royalty financing may also be coupled with an equity component, such as warrants to purchase our capital stock, which could also result in dilution of our existing stockholders’ ownership, and such dilution may be material. Additionally, if we raise additional capital through debt financing, we will have increased fixed payment obligations and may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt or making capital expenditures to meet specified financial ratios, and other operational restrictions, any of which could restrict our ability to commercialize ABP-450 in our proposed therapeutic indications or to operate as a business and may result in liens being placed on our assets. If we were to default on any of our indebtedness, we could lose such assets. Additional funding may not be available on acceptable terms, or at all. The global credit and financial markets have experienced volatility and disruptions recently, including diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates, and uncertainty about economic stability. If the equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly or more dilutive.

Our future success currently depends entirely on the successful and timely regulatory approval and commercialization of our only product candidate, ABP-450. The development and commercialization of pharmaceutical products is subject to extensive regulation, and we may not obtain regulatory approvals for ABP-450 in any of the indications for which we plan to develop it on a timely basis or at all.

Marketing approval of biologics in the United States requires the submission of a BLA to the FDA. A BLA must be supported by extensive clinical and preclinical data, as well as extensive information regarding pharmacology, chemistry, manufacturing and controls. FDA approval of a BLA is not guaranteed, and the review and approval process is an expensive and uncertain process that may take several years. The FDA also has substantial discretion in the approval process. The number and types of preclinical studies and clinical studies that will be required for BLA approval varies depending on the product candidate, the disease or the condition that the product candidate is designed to treat and the regulations applicable to any particular product candidate.

The FDA, the EMA, and other regulatory authorities can delay, limit or deny approval of a product candidate for many reasons, including the following:

a product candidate may not be deemed safe, effective, pure or potent;

the data from preclinical studies and clinical studies may not be deemed sufficient;

the FDA, the EMA and other regulatory agencies might not approve our third-party manufacturers’ processes or facilities;

deficiencies in the formulation, quality control, labeling, or specifications of a product candidate or in response to citizen petitions or similar documents filed in connection with the product candidate;

a general requirement intended to address risks associated with a class of drugs, such as a new risk evaluation and mitigation strategy, or REMS, requirement for botulinum toxins;

the enactment of new laws or promulgation of new regulations that change the approval requirements; or

the FDA, the EMA and other regulatory agencies may change their approval policies or adopt new regulations.

If ABP-450 fails to demonstrate safety and efficacy in our clinical studies or does not gain approval in any of our proposed therapeutic indications, our business and results of operations will be materially and adversely harmed.

We are currently pursuing three main therapeutic indications for ABP-450, and our business presently depends entirely on our ability to obtain regulatory approvals for ABP-450 for our planned indications and to successfully commercialize it in a timely manner. To date, as an organization, we have completed one clinical study related to the therapeutic use of ABP-450 for the treatment of cervical dystonia. We have no biological products currently approved for sale and we may never be able to develop marketable products. We are not permitted to market ABP-450 in the United States until we receive approval of a BLA from the FDA, in the European Union until we receive approval of a marketing authorization application, or MAA, from the EMA, in Canada until we receive approval of a new drug submission, or NDS, from Health Canada or in any other countries permitted under the Daewoong Agreement, until we receive the requisite approval from the applicable regulatory authorities in such countries. We will need to conduct a significant amount of clinical testing before we receive regulatory approval for any of our planned indications, and we do not know if or when we will receive any such approvals or whether we will need to make modifications or significant additional expenditures to obtain any such approvals. We can provide no assurances that ABP-450 will be successful in clinical studies or will ultimately receive regulatory approval in any therapeutic indication. Even if ABP-450 demonstrates efficacy, our injection protocols, including the selection of injection sites and amount of product injected at each injection site, may produce negative or inconclusive results or may result in the occurrence of serious adverse events. In addition, if we receive approval in one country for an indication, we may not receive a similar approval in any other jurisdiction, or in the same country for a different indication.

Even if regulatory approvals for one or more of our therapeutic indications are obtained, we may never be able to successfully commercialize ABP-450. We will need to transition at some point from a company with a development focus to a company capable of supporting commercial activities, including by obtaining approval for coverage and adequate reimbursement from third-party and

10

Table of Contents

government payors, but we may not be successful in such a transition. Accordingly, we may not be able to generate sufficient revenue through the sale of ABP-450 in each of our therapeutic indications to continue our business.

Clinical product development involves a lengthy, expensive and uncertain process. We may incur greater costs than we anticipate or encounter substantial delays or difficulties in our clinical studies.

We may not commercialize, market, promote or sell any product candidate without obtaining marketing approval from the FDA, the EMA or other regulatory agencies, and we may never receive such approvals. Clinical testing is expensive, is difficult to design and implement, can take many years to complete and is uncertain as to outcome. As a company, we are conducting and overseeing the conduct of preclinical and clinical studies of ABP-450 through contracts with CROs. We cannot guarantee that any clinical studies will be conducted as planned or completed on schedule, if at all. A failure of one or more clinical studies can occur at any stage of testing. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their product candidates performed satisfactorily in preclinical studies and clinical studies have nonetheless failed to obtain marketing approval of their products.

We may experience numerous unforeseen events prior to, during, or as a result of, clinical studies that could delay or prevent our ability to receive marketing approval or to commercialize ABP-450 in our proposed therapeutic indications, including the following:

Any inability to successfully complete preclinical and clinical development could result in additional costs to us or impair our ability to generate revenue from future product sales or other sources. In addition, if we make manufacturing or formulation changes to ABP-450, we may need to conduct additional testing to bridge our modified product candidate to earlier versions. Clinical study delays could also shorten any periods during which we may have the exclusive right to commercialize ABP-450, if approved in any currently proposed or future therapeutic indications, or allow our competitors to bring competing products to market before we do,

11

Table of Contents

which could impair our ability to successfully commercialize ABP-450 and may harm our business, financial condition, results of operations and prospects.

Additionally, if the results of our clinical studies are inconclusive or if there are safety concerns or serious adverse events associated with ABP-450 in any of our proposed therapeutic indications, we may:

Our product development costs will also increase if we experience delays in testing or obtaining marketing approvals. We do not know whether any of our preclinical studies or clinical studies will begin as planned, need to be restructured or be completed on schedule, if at all. Additionally, the COVID-19 pandemic’s impact on our projected milestones is uncertain and cannot be predicted with confidence.

Further, we, the FDA, a foreign regulatory authority, an ethics committee or an institutional review board may suspend our clinical studies at any time if it appears that we or our collaborators are failing to conduct a study in accordance with regulatory requirements, including the FDA’s current Good Clinical Practice, or GCP, regulations, that we are exposing participants to unacceptable health risks, or if the FDA, the EMA or other regulatory agency finds deficiencies in our investigational new drug applications, or INDs, or clinical study applications, respectively, or the conduct of these studies. Moreover, to the extent our filing schedule for a new IND is dependent on further preclinical or manufacturing progress, we may not be able to file such INDs on the timelines we expect. Therefore, we cannot predict with any certainty the schedule for commencement and completion of future clinical studies. If we experience delays in the commencement or completion of our clinical studies, or if we terminate a clinical study prior to completion, the commercial prospects of ABP-450 could be negatively impacted, and our ability to generate revenue from ABP-450 may be delayed.

Additionally, certain of our scientific advisors or consultants who receive compensation from us are likely to be investigators for our future clinical studies. Under certain circumstances, we may be required to report some of these relationships to the FDA. The FDA may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected interpretation of the study. The FDA may therefore question the integrity of the data generated at the applicable clinical study site and the utility of the clinical study itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA and may ultimately lead to the denial of marketing approval of ABP-450 in one or more indications. If we experience delays in the completion of, or termination of, any clinical study of ABP-450, the commercial prospects of ABP-450 will be harmed, and our ability to generate product revenue will be delayed. Moreover, any delays in completing our clinical studies will increase our costs, slow down our development and approval process and jeopardize our ability to commence product sales and generate revenues which may harm our business, financial condition and prospects significantly.

Enrollment and retention of patients in clinical studies is an expensive and time-consuming process and could be delayed, made more difficult or rendered impossible by multiple factors outside our control. If we experience delays or difficulties in enrolling patients in clinical studies, our receipt of necessary regulatory approval could be delayed or prevented.

Identifying and qualifying patients to participate in our clinical studies is critical to our success. The number of patients suffering from cervical dystonia is small and other indications we may pursue may have similarly small patient populations. We may encounter difficulties in enrolling patients in our clinical studies and may compete against other clinical studies for the same pool of potential patients, thereby delaying or preventing development and approval of ABP-450 in any of our proposed therapeutic indications. For example, the activation of investigators and sites for our migraine prevention Phase 2 clinical study was initially slower than we expected. Even once enrolled, we may be unable to retain a sufficient number of patients to complete any of our studies on a timely basis or at all. Patient enrollment and retention in clinical studies depends on many factors, including the size of the patient population, the nature of the study protocol, the existing body of safety and efficacy data, the number and nature of competing treatments and ongoing clinical studies of competing therapies for the same indication, the proximity of patients to clinical study sites, the eligibility criteria for the study and other factors we may not be able to control that may limit patients, principal investigators or staff or clinical site availability, including the COVID-19 pandemic.

Our clinical studies were, and may in the future be, affected by the COVID-19 pandemic or similar occurrences. For example, the COVID-19 pandemic caused us to delay enrollment to institute new procedures for the safety of patients and investigators and may in the future further impact patient enrollment in our ongoing clinical studies.

Further, if patients drop out of our clinical studies, miss scheduled doses or follow-up visits, or otherwise fail to follow clinical study protocols, whether as a result of the COVID-19 pandemic or otherwise, the integrity of data from our clinical studies may be compromised or not accepted by the FDA or other regulatory authorities, which would represent a significant setback for the applicable program.

Our efforts to build relationships with patient communities may not succeed, which could result in delays in patient enrollment in our clinical studies. Any negative results we may report in clinical studies of ABP-450 in any of our proposed therapeutic indications may make it difficult or impossible to recruit and retain patients in other clinical studies of that same product candidate. Delays or failures in planned patient enrollment or retention, whether as a result of the COVID-19 pandemic or otherwise, may result in increased costs, program delays or both, which could have a harmful effect on our ability to develop ABP-450 in any of our proposed therapeutic indications or could render further development impossible. In addition, we may rely on CROs and clinical study sites to ensure proper and timely conduct of our future clinical studies and, while we intend to enter into agreements governing their services, we will be limited in our ability to ensure their actual performance.

ABP-450 may cause undesirable side effects or have other properties that could delay or prevent its regulatory approval in any of our proposed therapeutic indications, limit its commercial potential or result in significant negative consequences following any potential marketing approval.

During the conduct of clinical studies, patients report changes in their health, including illnesses, injuries and discomforts, to their doctor. Often, it is not possible to determine whether or not the product candidate being studied caused or contributed to these conditions and regulatory authorities may draw different conclusions from us and require additional testing to confirm these determinations, if they occur. We are collecting data about ABP-450 from ongoing clinical and toxicology studies and any adverse events or undesirable side effects caused by, or other unexpected properties of, ABP-450 could cause us, any future collaborators, an Institutional Review Board, or IRB, or ethics committee or regulatory authorities to interrupt, delay or halt clinical studies of ABP-450 and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other regulatory authorities.

In addition, it is possible that as we test ABP-450 in larger, longer and more extensive clinical studies, or as use of ABP-450 becomes more widespread if it receives regulatory approval for any of our proposed indications, that illnesses, injuries, discomforts and other adverse events that were not observed in earlier studies conducted by us, or, in the case of ABP-450, by others using the same botulinum toxin, as well as conditions that did not occur or went undetected in previous studies, will be reported by subjects or patients. Many times, side effects are only detectable after investigational products are tested in large-scale pivotal studies or, in some cases, after they are made available to patients on a commercial scale after approval. If additional clinical experience indicates that ABP-450 has side effects or causes serious or life-threatening side effects in any of our proposed therapeutic indications, the development of ABP-450 in that indication may fail or be delayed. Additionally, there is the risk that as botulinum toxins other than

13

Table of Contents

ABP-450 are approved for and studied in connection with a broader range of diseases and conditions and across a more diverse population, additional safety signals and other adverse events may be identified. All botulinum toxin products are required to include a class labeling that contains a boxed warning related to safety and we could be required to include additional warnings on our product labeling, if approved.

If ABP-450 receives regulatory approval, and we or others identify undesirable side effects of ABP-450, a number of potentially significant negative consequences could result, such as regulatory authorities revoking such approval or imposing additional restrictions on the marketing and promotion of the product, or we may be required to recall the product or implement changes to the way the product is administered.

We could also be sued and held liable for harm caused to patients, which could hinder commercial acceptance of ABP-450 and adversely affect our business, financial condition, results of operations and prospects.

Results of other parties’ clinical studies involving the same or a nearly identical botulinum toxin complex as ABP-450, or results in any preclinical studies we conduct, may not be predictive of future results of our clinical studies.

Success in clinical studies conducted by Daewoong and Evolus, Inc., or Evolus, involving a botulinum toxin that is identical or nearly identical to ABP-450 does not ensure that any clinical studies we conduct using ABP-450 will be successful and we will still need to submit our independently generated data to applicable regulatory agencies to support regulatory approval of ABP-450 in any of our proposed therapeutic indications. Similarly, success in any preclinical studies or clinical studies that we conduct will not ensure that later clinical studies will be successful. A number of companies in the biotechnology and pharmaceutical industries have suffered significant setbacks in clinical studies, even after positive results in earlier preclinical studies and earlier clinical studies. These setbacks have been caused by, among other things, preclinical findings made while clinical studies were underway and safety or efficacy observations made in clinical studies, including previously unreported adverse events. Notwithstanding any potential promising results in earlier studies, we cannot be certain that we will not face similar setbacks.

Additionally, our clinical studies may utilize an “open-label” trial design. An “open-label” clinical trial is one where both the patient and investigator know whether the patient is receiving the investigational product candidate for either an existing approved drug or placebo. Most typically, open-label clinical studies test only the investigational product candidate and may do so at different dose levels. Open-label clinical studies are subject to various limitations that may exaggerate any therapeutic effect as patients in open-label clinical studies are aware when they are receiving treatment. Open-label clinical studies may be subject to a “patient bias” where patients perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. In addition, open-label clinical studies may be subject to an “investigator bias” where those assessing and reviewing the physiological outcomes of the clinical studies are aware of which patients have received treatment and may interpret the information of the treated group more favorably given this knowledge. The results from an open-label trial may not be predictive of future clinical trial results with any of our product candidates when studied in a controlled environment with a placebo or active control.

Interim, topline or preliminary data from our clinical studies that we may announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose interim, topline or preliminary data from our clinical studies, which are based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a full analysis of all data related to the particular study. Interim and preliminary data for the studies we may complete are subject to the risk that one or more clinical outcomes may materially change as patient enrollment continues or more patient data become available. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. Interim, topline and preliminary data also remains subject to audit and verification procedures that may result in the final data being materially different from the preliminary data previously published. As a result, the interim, topline, or preliminary results that we report may differ from future results of the same trials, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated, and any interim, topline or preliminary data should be viewed with caution until final data is available. Material adverse changes in the final data could result in significant harm to our business prospects.

14

Table of Contents

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of our product candidate or product and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical study is based on what is typically extensive information, and you or others may not agree with what we determine is the material or otherwise appropriate information to include in our disclosure, and any information we determine not to disclose may ultimately be deemed significant with respect to future decisions, conclusions, views, activities or otherwise regarding a particular pharmaceutical or biological product, pharmaceutical or biological product candidate or our business. If the interim, topline or preliminary data that we report differ from actual results, or if others, including regulatory authorities, disagree with the conclusions reached, our ability to obtain approval for and commercialize our product candidate in any currently proposed or future therapeutic indications may be harmed, which could harm our business, operating results, prospects or financial condition.

Due to our limited resources and access to capital, we must prioritize development of certain therapeutic uses of ABP-450; these decisions may prove to be wrong and may adversely affect our business.

While our initial focus is on the development and approval of ABP-450 for the treatment of migraine, cervical dystonia and gastroparesis, a key element of our strategy is to identify additional conditions for which ABP-450 may be an effective therapy. However, there can be no assurances that we will be successful in identifying such conditions. Even if we are successful in identifying such conditions, we may experience difficulties in identifying a proper treatment regimen, or we may fail to secure regulatory approval for a particular indication. If we are unable to gain regulatory approval for indications in addition to the indications for the treatment of migraine, cervical dystonia and gastroparesis on which we are currently focused, or if FDA or other regulatory agencies require us to pursue a narrower indication than we have currently identified, we may be limited in our ability to grow our business.

Efforts to identify and pursue additional therapeutic uses of ABP-450 require substantial technical, financial and human resources, regardless of whether they are ultimately successful. Because we have limited financial and personnel resources, we may forgo or delay pursuit of opportunities with potential target indications that later prove to have greater commercial potential or a greater likelihood of success. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. We may focus our efforts and resources on potential therapeutic uses of ABP-450 that ultimately prove to be unsuccessful.

We may not be successful in obtaining an original BLA that contemplates exclusively therapeutic uses of ABP-450.

In order to market a biological product, an entity must submit and receive approval of a BLA. When a BLA application is approved in the first instance, it is an “original BLA” which is assigned a BLA number by the FDA. An approved “original BLA” may be supplemented, or amended, to incorporate changes, such as new indications, which the FDA must also approve. A BLA holder is legally responsible for all regulatory obligations associated with the BLA, including each supplement thereto, and is the only party that is authorized to submit a supplement. The form of BLA, original versus a supplement, is important because payors will generally consider the pricing for all products falling under the same BLA together when calculating reimbursement rates. Existing botulinum toxins, including Botox, are approved under a single BLA for both therapeutic and cosmetic indications. As a result, when payors calculate the average selling price, or ASP, of other botulinum toxins they include the sales prices of both therapeutic and cosmetic sales. The inclusion of a lower cosmetic sales price in the calculation of the ASP can cause physicians to lose money when treating patients with existing botulinum toxins and also creates a deterrent to providing payors and/or providers with rebates or other financial incentives.

Part of our regulatory strategy includes pursuing an original BLA that contemplates exclusively therapeutic uses of ABP-450. We are aware that Evolus has obtained a BLA for cosmetic indications of its Jeuveau product, which is substantially similar to ABP-450. However, given we are a separate legal entity from Evolus, we do not hold a BLA that could be supplemented to add our target indications. As such, we believe the filing of an original BLA for ABP-450 is the appropriate path for approval and, by filing an original BLA, we can limit it to exclusively therapeutic uses. If we are successful in obtaining an original BLA for therapeutic indications of ABP-450, we believe the ASP for ABP-450 would be calculated using only therapeutic sales, which should facilitate consistent and favorable reimbursement to physicians when they choose to use ABP-450 for therapeutic treatments, as well as our ability to provide payors and/or providers with rebates and other financial incentives. However, we cannot assure you that we will be able to obtain such a BLA, and we are aware of other companies that sell botulinum toxins for both therapeutic and aesthetic indications that have experienced regulatory issues and denials by the FDA that led them to abandon the approach of applying for

15

Table of Contents

separate original BLAs that would cover the separate markets. We believe these denials occurred, in part, because in those instances the applicant already possessed a BLA for the product in a different indication. In the event we are not able to obtain an original BLA, we may not be able to ensure the consistent pricing that we believe an original BLA would offer, and the anticipated ASP of our products could be adversely affected.

Even if ABP-450 receives regulatory approval for any of our proposed indications, it may fail to achieve the broad degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success.

Even if ABP-450 receives marketing approval for one or more therapeutic indications, it may nonetheless fail to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community for those indications. The commercial success of ABP-450, if approved in any currently proposed or future therapeutic indications, will depend significantly on the broad adoption and use of the resulting product by physicians for approved indications. The degree of market acceptance of any product candidate, if approved for commercial sale, will depend on a number of factors, including but not limited to:

Our efforts to educate physicians, patients, third party payors and others in the medical community on the benefits of our product candidates, if approved, may require significant resources and may never be successful.

If ABP-450 fails to gain market acceptance, this will have a material adverse impact on our ability to generate revenues to provide a satisfactory, or any, return on our investments. Even if some therapeutic indications achieve market acceptance, the market may prove not to be large enough to allow us to generate significant revenues.

16

Table of Contents

Even if we receive regulatory approval for ABP-450 in any therapeutic indication, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense, limit or delay additional regulatory approvals, limit or prohibit commercial distribution, prevent continued investigation and research and subject us to penalties if we fail to comply with applicable regulatory requirements. Additionally, ABP-450, if approved in any therapeutic indication, could be subject to labeling and other restrictions and market withdrawal and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with our products.

If regulatory approval is granted, ABP-450 will be subject to continual regulatory review by the FDA, the EMA and other similar regulatory authorities. Any regulatory approvals that we or our current or future collaborators receive for ABP-450 in any currently proposed or future therapeutic indication may also be subject to limitations on the approved indications for which the product may be marketed or to the conditions of approval, or such approvals may contain requirements for potentially costly post-marketing testing, including Phase IV clinical studies, and surveillance to monitor the safety and efficacy of the product. In addition, if the applicable regulatory agency approves ABP-450 in any therapeutic indication, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports and registration, as well as continued compliance with cGMP requirements and GCPs, for any clinical studies that we conduct post-approval. Later discovery of previously unknown problems with ABP-450, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

Additionally, if ABP-450 receives marketing approval for any of our proposed indications, the FDA could require us to adopt a REMS to ensure that the benefits of the therapy outweigh its risks, which may include, among other things, a medication guide outlining the risks for distribution to patients and a communication plan to health care practitioners. Authorities in other jurisdictions

also may take similar actions. Any of these events could prevent us from achieving or maintaining market acceptance of ABP-450 in the proposed therapeutic indications and could significantly harm our business, prospects, financial condition and results of operations.

Regulatory policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of ABP-450 in any of our proposed therapeutic indications. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow to or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained and we may not achieve or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations.

In addition, given the similarity of ABP-450 to Jeuveau, any adverse developments with respect to Jeuveau, including adverse events or changes in regulatory status, may also directly impact the development, commercialization or regulation of ABP-450, if approved.

Even if we receive marketing approval, coverage and adequate reimbursement may not be available for ABP-450 in any currently proposed or future therapeutic indications, which could make it difficult for us to sell the product profitably.

Market acceptance and sales of ABP-450, if approved, will depend in part on the extent to which reimbursement for the product and related treatments will be available from third-party payors, including government health administration authorities, managed care organizations and other private health insurers.

Obtaining coverage and adequate reimbursement approval for a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide supporting scientific, clinical and cost-effectiveness data for the use of our products to the payor.

Third-party payors decide which therapies they will pay for and establish reimbursement levels. While no uniform policy for coverage and reimbursement exists in the United States, third-party payors often rely upon Medicare coverage policy and payment limitations in setting their own coverage and reimbursement policies. However, decisions regarding the extent of coverage and amount of reimbursement to be provided for ABP-450 will be made on a payor-by-payor basis. Therefore, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage, and adequate reimbursement, for the product or any related treatments. Additionally, a third-party payor’s decision to provide coverage for a therapy does not imply that an adequate reimbursement rate will be approved. Each payor determines whether or not it will provide coverage for a therapy, what amount it will pay the manufacturer for the therapy and on what tier of its formulary it will be placed. The position on a payor’s list of covered drugs and biological products, or formulary, generally determines the co-payment that a patient will need to make to obtain the therapy and can strongly influence the adoption of such therapy by patients and physicians. Patients who are prescribed treatments for their conditions and providers prescribing such services generally rely on third-party payors to reimburse all or part of the associated healthcare costs. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our products. In addition, because certain of our proposed indications of ABP-450 will require the product to be physician-administered, separate reimbursement for the product itself may or may not be available. Instead, the administering physician may only be reimbursed for providing the treatment or procedure in which our product is used.

There may be significant delays in obtaining such coverage and reimbursement for newly approved products, and coverage may be more limited than the purposes for which the product is approved by the FDA. Moreover, eligibility for coverage and reimbursement does not imply that a product will be paid for in all cases or at a rate that covers our costs, including research, development, intellectual property, manufacture, sale and distribution expenses. Interim reimbursement levels for new products, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the product and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost products and may be incorporated into existing payments for other services. Net prices for products may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors, by any future laws limiting pharmaceutical prices and by any future relaxation of laws that presently restrict imports of product from countries where they may be sold at lower prices than in the United States.

Third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. We cannot be sure that coverage and reimbursement will be available for any product that we commercialize and, if reimbursement is available, what the level of reimbursement will be. Inadequate coverage and reimbursement may impact the demand for, or the price of, any product for which we obtain marketing approval. If coverage and adequate reimbursement are not available, or are available only at limited levels, we may not be able to successfully commercialize ABP-450.

Outside the United States, international operations are generally subject to extensive governmental price controls and other market regulations, and we believe a continued emphasis on cost containment initiatives in Europe, Canada and other countries could continue to put pressure on the pricing and usage of our product candidates. In many countries, the prices of medical products are subject to varying price control mechanisms as part of national health systems. Other countries allow companies to fix their own prices for medical products, but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for our product candidates. Accordingly, in markets outside the United States, the reimbursement for our products may be reduced compared with the United States and may be insufficient to generate commercially reasonable revenue and profits.

The delivery of health care in the European Union, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than European Union, law and policy. National governments and health service providers have different priorities and approaches to the delivery of healthcare and the pricing and reimbursement of products in that context. In general, however, the health care budgetary constraints in most European Union member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Coupled with ever increasing European Union and national regulatory burdens on those wishing to develop and market products, this could prevent or delay marketing approval of our product candidates, restrict or regulate post approval activities and affect our ability to commercialize any products for which we obtain marketing approval.

Moreover, increasing efforts by governmental and third party payors in the European Union, the United States and other jurisdictions to cap or reduce health care costs may cause such organizations to limit both coverage and the level of reimbursement for newly approved products and, as a result, they may not cover or provide adequate payment for our product candidates. We expect to experience pricing pressures in connection with the sale of any of our product candidates due to the trend toward managed health care, the increasing influence of health maintenance organizations and additional legislative changes. The downward pressure on health care costs in general, particularly prescription drugs and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products.

ABP-450, if approved in any currently proposed or future therapeutic indications, will face significant competition and our failure to effectively compete may prevent us from achieving significant market penetration and expansion.

The pharmaceutical industry is highly competitive and requires an ongoing, extensive search for technological innovation. It also requires, among other things, the ability to effectively discover, develop, test and obtain regulatory approvals for novel products, as well as the ability to effectively commercialize, market and promote approved products, including communicating the effectiveness, safety and value of products to actual and prospective customers and medical professionals. Numerous companies are engaged in the development, manufacture and marketing of products competitive with those that we are developing.

Our primary competitors for ABP-450 in the injectable botulinum toxin pharmaceutical market for therapeutic use are:

19

Table of Contents

We are also aware of competing botulinum toxins currently being developed or commercialized in the United States, European Union, Asia, South America and other markets. While some of these products may not meet United States regulatory standards, the companies operating in these markets may be able to produce products at a lower cost than United States and European manufacturers. In addition to the injectable botulinum toxin dose forms, we are aware that other companies are developing topical botulinum toxins for therapeutic indications.

We will also face competition in our target therapeutic markets from other pharmaceutical products.

For the treatment of cervical dystonia, in addition to other injectable botulinum toxins, we will face competition from orally administered anticholinergic, GABA receptor agonist, benzodiazepine, dopaminergic and anticonvulsant pharmaceuticals. For the treatment of migraine, we will face competition from calcitonin gene-related peptide agonists, or CGRPs, including Aimovig (erenumab) marketed by Amgen Inc., Ajovy (fremenezumab) marketed by Teva Pharmaceutical Industries Ltd., and Emgality (galcenezumab) marketed by Eli Lilly and Company, as well as certain orally administered anti-epileptic, beta-blocker and triptan pharmaceuticals. The FDA has also accepted a New Drug Application for vazegepant, marketed by Pfizer Inc., to be used as an intranasal formulation for both the acute treatment and prevention of migraine. For the treatment of gastroparesis, we will face competition from prokinetic agents, including REGLAN (metoclopramide), which is the only medication currently approved by FDA for the treatment of gastroparesis.

Many of our competitors have greater financial and other resources than we have. This enables them, among other things, to leverage their financial resources to make greater R&D, marketing and promotion investments than us. Our competitors may also have more experience and expertise in obtaining marketing approvals from the FDA and other regulatory authorities. Our technologies and products may be rendered obsolete or uneconomical by technological advances or entirely different approaches developed by one or more of our competitors. For example, Revance has published data related to the treatment of cervical dystonia that indicates that its botulinum toxin may have a duration of effect of at least 24 weeks, which may compare favorably to the duration of effect of ABP-450. As more companies develop new intellectual property in our markets, the possibility of a competitor acquiring patent or other rights that may limit our products or potential products increases, which could lead to litigation. In addition to product development, testing, approval and promotion, other competitive factors in the pharmaceutical industry include industry consolidation, product quality and price, product technology, reputation, customer service and access to technical information.

If approved, ABP-450 may face competition sooner than anticipated.

With the enactment of the Biologics Price Competition and Innovation Act of 2009, or the BPCIA, as part of the Patient Protection and Affordable Care Act, an abbreviated pathway for the approval of biological products that are biosimilar to or interchangeable with an FDA-licensed reference biological product was created. The abbreviated regulatory pathway establishes legal authority for the FDA to review and approve biosimilar biologics. Under the BPCIA, an application for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDA until twelve years from the date on which the reference product was first licensed. During this twelve-year period of exclusivity, another company may still market a competing version of the reference product if the FDA approves a full BLA for the competing product containing the sponsor’s own preclinical data and data from adequate and well-controlled clinical studies to demonstrate the safety, purity and potency of their product. The law is complex and is still being interpreted and implemented by the FDA. As a result, its ultimate impact, implementation, and meaning are subject to uncertainty. While it is uncertain when such processes intended to implement the BPCIA may be fully adopted by the FDA, any such processes could have a material adverse effect on the future commercial prospects for our biological products.

We have not determined whether ABP-450 would qualify for the twelve-year period of exclusivity based on submission of an original BLA, a shorter period or any exclusivity at all. Even if we are able to obtain separate twelve-year exclusivity, or a shorter exclusivity period, there is a risk that any exclusivity could be shortened due to congressional action or otherwise, that the FDA attempts to adopt an alternate interpretation of law that precludes exclusivity, or that the FDA will not consider ABP-450 to be a reference product for competing products, potentially creating the opportunity for competition sooner than anticipated. Moreover, the

20

Table of Contents

extent to which a biosimilar product, once approved, will be substituted for any one of our reference products in a way that is similar to traditional generic substitution for non-biological products is not yet clear and will depend on a number of marketplace and regulatory factors that are still developing. If we are unable to obtain an original BLA, and ABP-450 receives a supplemental BLA, we would not qualify for the exclusivity period.

If we are unable to establish sales and marketing capabilities on our own or through third parties, we will be unable to successfully commercialize ABP-450, if approved in any proposed therapeutic indication, or generate product revenue.

We do not have a sales or marketing infrastructure and have little experience in the sale, marketing, or distribution of pharmaceutical products. To successfully commercialize ABP-450, if approved in any proposed therapeutic indication, in the United States, the European Union, Canada and other jurisdictions we may seek to enter, we will need to build out our sales and marketing capabilities, either on our own or with others. The establishment and development of our own commercial team or the establishment of a contract sales force to market ABP-450 will be expensive and time-consuming and may divert significant management focus and resources, potentially delaying any product launch. Moreover, we cannot be certain that we will be able to successfully develop this capability, given that we have no experience as a company in commercializing products. We may seek to enter into collaborations with other entities to utilize their established marketing and distribution capabilities, but we may be unable to enter into or maintain such agreements on favorable terms or at all. We can provide no assurance that any future collaborators will provide effective sales forces or marketing and distribution capabilities. We compete with many companies that currently have extensive, experienced and well-funded marketing and sales operations to recruit, hire, train and retain marketing and sales personnel, and will have to compete with those companies to recruit, hire, train and retain any of our own marketing and sales personnel. We will likely also face competition if we seek third parties to assist us with the sales and marketing efforts of ABP-450 in our proposed therapeutic indications. Without an internal team or the support of a third party to perform marketing and sales functions, we may be unable to compete successfully against these more established companies.

We will need to grow the size of our organization, and we may experience difficulties in managing this growth.

As of June 30, 2023, we had nine employees. As the clinical development of ABP-450 progresses, we also expect to experience significant growth in the number of our employees and the scope of our operations, particularly in the areas of research, development, regulatory affairs and, if ABP-450 receives marketing approval for any of our proposed indications, sales, marketing and distribution. In addition, we also expect to hire additional personnel in order to operate as a public company. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities, and continue to recruit and train additional qualified personnel. In addition, we must effectively integrate, develop and motivate a growing number of new employees, and maintain the beneficial aspects of our corporate culture. The expansion of our operations may lead to significant costs and may divert our management and business development resources. We may not be able to effectively manage the expansion of our operations or recruit and train additional qualified personnel. Any inability to manage growth could delay the execution of our development and strategic objectives or disrupt our operations.

We currently rely, and for the foreseeable future will continue to rely, in substantial part on third parties, including independent organizations, advisors and consultants, and CROs to provide certain services to support and perform our operations. There can be no assurance that the services of these third parties will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage our outsourced activities or if the quality, accuracy or quantity of the services provided, in particular the services provided by our CROs, is compromised for any reason, our clinical studies may be delayed or terminated, and we may not be able to obtain, or may be substantially delayed in obtaining, regulatory approval of ABP-450 in any of our proposed therapeutic indications or otherwise advance our business. There can be no assurance that we will be able to manage our existing consultants or find other suitable outside contractors and consultants on economically reasonable terms, or at all.

Our employees, independent contractors, consultants, commercial collaborators, principal investigators, vendors and other agents may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements.

We are exposed to the risk that our employees, independent contractors, consultants, commercial collaborators, principal investigators, vendors and other agents may engage in fraudulent conduct or other illegal activity. Misconduct by these parties could include intentional, reckless or negligent conduct or disclosure of unauthorized activities to us that violates applicable regulations, including those laws requiring the reporting of true, complete and accurate information to regulatory agencies, manufacturing

standards, and federal and state healthcare laws and regulations. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. We could face liability under the federal Anti-Kickback Statute and similar state laws. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, referrals, customer incentive programs and other business arrangements. Misconduct by these parties could also involve the improper use of individually identifiable information, including, without limitation, information obtained in the course of clinical studies, which could result in significant regulatory sanctions and serious harm to our reputation. Further, should violations include promotion of unapproved (off-label) uses of one or more of our products, we could face significant regulatory sanctions for unlawful promotion, as well as substantial penalties under the federal False Claims Act, or FCA, and similar state laws. Similar concerns could exist in jurisdictions outside of the United States as well. We adopted, in connection with the completion of the Business Combination, a code of conduct applicable to all of our employees, but it is not always possible to identify and deter misconduct by employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. The precautions we take to detect and prevent misconduct may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, imprisonment, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations of noncompliance with these laws, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business, financial condition and results of operations.

Our proposed international operations will expose us to risks, and failure to manage these risks may adversely affect our operating results and financial condition.

We expect to have operations both inside and outside the United States if ABP-450 is approved for commercial sale in multiple jurisdictions. International operations are subject to a number of inherent risks, and our future results could be adversely affected by a number of factors if we seek and obtain the necessary approvals, including:

22

Table of Contents

These and other factors associated with international operations could harm our ability to gain future revenue and, consequently, materially impact our business, results of operations and financial condition.

If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of ABP-450.

We face an inherent risk of product liability as a result of the clinical testing of ABP-450 and will face an even greater risk if we commercialize any products. For example, we may be sued if any product we develop allegedly causes injury or is found to be otherwise unsuitable during product testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability and a breach of warranties. Claims could also be asserted under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our products. Even a successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:

23

Table of Contents

Our inability to obtain and maintain sufficient product liability insurance at an acceptable cost and scope of coverage to protect against potential product liability claims could prevent or inhibit the commercialization of ABP-450 in any current or future proposed therapeutic indication. We currently carry product liability insurance covering our clinical studies. Although we maintain such insurance, any claim that may be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance policies also have various exclusions and deductibles, and we may be subject to a product liability claim for which we have no coverage. We will have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts. Moreover, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses. If and when we obtain approval for marketing ABP-450, we intend to expand our insurance coverage to include the sale of ABP-450; however, we may be unable to obtain this liability insurance on commercially reasonable terms.

If we fail to attract and keep senior management and key scientific personnel, we may be unable to successfully develop ABP-450 in any of our proposed therapeutic indications, conduct our clinical studies and commercialize ABP-450.

Our success depends in part on our continued ability to attract, retain and motivate highly qualified management. We believe that our future success is highly dependent upon the contributions of our senior management, particularly Marc Forth, our Chief Executive Officer, as well as other members of our senior management team. The loss of services of any of these individuals could delay or prevent the successful development of our product pipeline, completion of our planned clinical studies or the commercialization of ABP-450 in each of our therapeutic indications or any future products we develop.

In addition, we could experience difficulties attracting and retaining qualified employees in the future. For example, competition for qualified personnel in the pharmaceuticals field is intense due to the limited number of individuals who possess the skills and experience required by our industry. We may not be able to attract and retain quality personnel on acceptable terms, or at all. In addition, to the extent we hire personnel from competitors, we may be subject to allegations that they have been improperly solicited or that they have divulged proprietary or other confidential information or that their former employers own their research output.

Our business involves the use of hazardous materials, and we and our third-party manufacturer and supplier must comply with environmental laws and regulations, which can be expensive and restrict how we do business.

Our R&D and manufacturing activities in the future may, and Daewoong’s manufacturing and supplying activities presently do, involve the controlled storage, use and disposal of hazardous materials, including botulinum toxin type-A, a key component of ABP-450, and other hazardous compounds. We and Daewoong are subject to laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. In some cases, these hazardous materials and various wastes resulting from their use are stored at Daewoong’s facilities pending their use and disposal. We and Daewoong cannot eliminate the risk of contamination, which could cause an interruption of Daewoong’s manufacturing processes, our commercialization efforts or our business operations and could cause environmental damage resulting in costly clean-up and liabilities under applicable laws and regulations governing the use, storage, handling and disposal of these materials and specified waste products. Although we believe that the safety procedures utilized by Daewoong for handling and disposing of these materials generally comply with the standards prescribed by these laws and regulations, this may not eliminate the risk of accidental contamination or injury from these materials. In such an event, we may be held liable for any resulting damages and such liability could exceed our resources, and state or federal or other applicable authorities may curtail our use of certain materials and interrupt our business operations. Furthermore, environmental laws and regulations are complex, change frequently and have tended to become more stringent.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

Under Sections 382 and 383 of the Code, if a corporation undergoes an “ownership change,” generally defined as a greater than 50 percentage point change (by value) in its equity ownership by one or more 5% shareholders over a rolling three-year period, the corporation’s ability to use its pre-change net operating loss carryforwards, or NOLs, and other pre-change tax attributes, such as research tax credits, to offset its post- change taxable income or income tax liabilities, as applicable, may be limited. As of December 31, 2021, Old AEON had $54.3 million of federal NOLs available to offset our future federal taxable income, if any, and federal research and development tax credit carryforwards of $1.6 million. These federal research and development tax credit carryforwards and $54.3 million of our federal NOLs expire at various dates in 2036 or 2037. We may experience ownership changes in the future as a result of subsequent shifts in our stock ownership. As a result, if we earn net taxable income, our ability to use our

24

Table of Contents

pre-change NOLs to offset federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. Similar rules may apply under state tax laws. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. Old AEON had $24.0 million of state NOLs as of December 31, 2021.

Changes in tax laws may impact our future financial position and results of operations.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, or interpreted, changed, modified or applied adversely to us, any of which could adversely affect our business operations and financial performance. We are currently unable to predict whether such changes will occur and, if so, the ultimate impact on our business. To the extent that such changes have a negative impact on us or our suppliers, including as a result of related uncertainty, these changes may materially and adversely impact our business, financial condition, results of operations and cash flows.

Risks Related to our Reliance on Third Parties

We rely on the Daewoong Agreement to provide us exclusive rights to commercialize and distribute ABP-450 in certain territories. Any termination or loss of significant rights, including exclusivity, under the Daewoong Agreement would materially and adversely affect our development or commercialization of ABP-450.

Pursuant to the Daewoong Agreement, we have secured an exclusive license from Daewoong, a South Korean pharmaceutical manufacturer, to import, distribute, promote, market, develop, offer for sale and otherwise commercialize and exploit ABP-450 for therapeutic indications in certain territories including the United States, the European Union, the United Kingdom, Canada, Australia, Russia, Commonwealth of Independent States and South Africa. The Daewoong Agreement imposes on us obligations relating to exclusivity, territorial rights, development, regulatory approval, commercialization, payment, diligence, sublicensing, intellectual property protection and other matters. For example, we are obligated to use commercially reasonable efforts to obtain regulatory approval of ABP-450 and obtain from Daewoong all of our product supply requirements for ABP-450. In addition, under the Daewoong Agreement, we are required to submit our commercialization plan to a Joint Steering Committee, or JSC, comprised of an equal number of development and commercial representatives from Daewoong and us, for review and input. Although the Daewoong Agreement provides us with final decision-making power regarding the marketing, promotion, sale and/or distribution of ABP-450, any disagreement among the JSC would be referred to Daewoong’s and our respective senior management for resolution if the JSC is unable to reach a decision within thirty days, which may result in a delay in our ability to implement our commercialization plan or harm our working relationship with Daewoong. Further, under the Daewoong Agreement, we may not purchase, sell or distribute any injectable botulinum toxin that is launched in the covered territories after the effective date of the Daewoong Agreement other than ABP-450 in a covered territory or sell ABP-450 outside a covered territory.

The initial term of the Daewoong Agreement will expire on the later of December 20, 2029 or the fifth anniversary of our receipt of approval from the relevant governmental authority necessary to market and sell ABP-450 in any of the aforementioned territories. The Daewoong Agreement will renew for unlimited additional three-year terms after the expiration of the initial term. We or Daewoong may terminate the Daewoong Agreement if the other party breaches any of its duties or obligations and such breach continues without cure for ninety days, or thirty days in the case of a payment default, or, if such breach is not capable of being cured, immediately by delivery of written notice. The Daewoong Agreement will terminate without notice upon our bankruptcy or insolvency or if we assign our business or the Daewoong Agreement in whole or in part for the benefit of creditors.

We will be the sole owner of any marketing authorization we pursue related to therapeutic indications of ABP-450 in a covered territory. This will include ownership of any BLA that we may submit to the FDA, MAA that we may submit to the EMA, NDS that we may submit to Health Canada, and any other approvals that we may receive in a covered territory. However, if we do not renew the Daewoong Agreement following any initial or renewal term, or if Daewoong terminates the Daewoong Agreement due to a breach by us, we are obligated to transfer our rights in such marketing authorizations to Daewoong.

If we breach any material obligations, or use the intellectual property licensed to us in an unauthorized manner, we may be required to pay damages to Daewoong and Daewoong may have the right to terminate our license. Any termination or loss of rights under the Daewoong Agreement would materially and adversely affect our ability to develop and commercialize ABP-450, which in turn would have a material adverse effect on our business, operating results and prospects. If we were to lose our rights under the Daewoong Agreement, we believe it would be difficult or impossible for us to find an alternative supplier of a botulinum toxin type-A

25

Table of Contents

complex. In addition, to the extent the alternative supplier has not secured regulatory approvals in a jurisdiction, we would have to expend significant resources, including performing additional clinical studies, to obtain regulatory approvals that may never be obtained or require several years to obtain, which could significantly delay commercialization. We may be unable to raise additional capital to fund our operations during this extended time on terms acceptable to us or at all. If we were to commercialize ABP-450 and later experience delays as a result of a dispute with Daewoong, the demand for ABP-450 could be materially and adversely affected.

For more information on the Daewoong Agreement, including a further explanation of our obligations, please see “Information About AEON — Daewoong License and Supply Agreement.”

We currently rely solely on Daewoong to manufacture ABP-450, and as such, any production or other problems with Daewoong could adversely affect us. The manufacture of biologics is complex and Daewoong may encounter difficulties in production that may impact our ability to provide supply of ABP-450 for clinical studies, our ability to obtain marketing approval, or our ability to obtain commercial supply of our products, which, if approved, could be delayed or stopped.

We have no experience in biologic manufacturing and do not own or operate, and we do not expect to own or operate, facilities for product manufacturing, storage and distribution, or testing. We depend solely upon Daewoong to manufacture ABP-450. Any failure or refusal by Daewoong to supply ABP-450 could delay, prevent or impair our clinical development or commercialization efforts. The Daewoong Agreement also provides for a fixed price related to the supply of ABP-450 for ten years or for five years after the receipt of regulatory approvals, and if a change in price were to occur, it could impair our ability to obtain necessary quantities of ABP-450. Although alternative sources of supply may exist, the number of third-party suppliers with the necessary manufacturing and regulatory expertise and facilities is limited, and it could be expensive and take a significant amount of time to arrange for alternative suppliers, which could have a material adverse effect on our business. New suppliers of any product candidate would be required to qualify under applicable regulatory requirements and would need to have sufficient rights under applicable intellectual property laws to the method of manufacturing the product candidate. Obtaining the necessary FDA approvals or other qualifications under applicable regulatory requirements and ensuring non-infringement of third-party intellectual property rights could result in a significant interruption of supply and could require the new manufacturer to bear significant additional costs which may be passed on to us. We will also need to verify, such as through a manufacturing comparability study, that any new contract manufacturing organization or manufacturing process will produce our product candidate according to the specifications previously submitted to the FDA or another regulatory authority. We may be unsuccessful in demonstrating the comparability of clinical suppliers which could require conducting additional clinical studies.

In addition, there are risks associated with large scale manufacturing for clinical studies or commercial scale including, among others, cost overruns, potential problems with process scale-up, process reproducibility, stability issues, compliance with good manufacturing practices, lot consistency and timely availability of raw materials. Even if we obtain marketing approval for ABP-450, there is no assurance that Daewoong will be able to manufacture the approved product to specifications acceptable to the FDA or other comparable foreign regulatory authorities, to produce it in sufficient quantities to meet the requirements for the potential commercial launch of the product or to meet potential future demand. If Daewoong is unable to produce sufficient quantities for clinical studies, including preclinical studies, or for commercialization, our development and commercialization efforts would be impaired, which would have an adverse effect on our business, financial condition, results of operations and growth prospects.

Our reliance on Daewoong entails additional risks, including reliance on Daewoong for regulatory compliance and quality assurance, the possible breach of the Daewoong Agreement by Daewoong, and the possible termination or nonrenewal of the Daewoong Agreement at a time that is costly or inconvenient for us. Our failure, or the failure of Daewoong, to comply with applicable regulations, such as cGMP, which includes, among other things, quality control, quality assurance and the maintenance of records and documentation, could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of the product candidate or drugs, import alerts or detentions preventing import of product into the United States or other territories, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of ABP-450. Our dependence on Daewoong also subjects us to all of the risks related to Daewoong’s business, which are all generally beyond our control. Daewoong’s ability to perform its obligations under the Daewoong Agreement is dependent on its operational and financial health, which could be negatively impacted by several factors, including changes in the economic, political and legislative conditions in South Korea and the broader region in general and the ability of Daewoong to continue to successfully attract customers and compete in its market. Daewoong’s lack of familiarity with, or inability to effectively operate, the facility and produce products of consistent quality, may harm our ability to compete in our market.

In addition, we are ultimately responsible for distribution of products under any authorization or approval we hold to investigate or market ABP-450. We do not own a manufacturing facility and we have never supervised manufacturing operations, but we have regulatory obligations to review batch records and release of the investigational product for our clinical studies. Further, we will have similar regulatory obligations if the product is marketed and could be held responsible for any distribution of adulterated or misbranded ABP-450, even if caused by Daewoong’s noncompliance.

The FDA conducted a cGMP and pre-approval inspection of Daewoong’s manufacturing facility in South Korea related to Evolus’ BLA for Jeuveau from November 8, 2017 to November 17, 2017. At the end of the inspection, the FDA issued an FDA Form 483 with ten inspectional observations of regulatory noncompliance to Daewoong. The Form 483 included observations relating to the need for adherence to improved procedures, processes and documentation relating to investigations of and corrective actions for non-compliance with specifications for batches and components, environmental monitoring, drug substance testing, computer system access, material handling and staff training. Daewoong timely responded to the FDA with a plan for implementing corrective actions related to these observations. Daewoong provided complete responses to the Form 483; however, the time to correct the observations, submit the complete response and FDA review and acceptance of the responses delayed approval of Evolus’ BLA. None of the FDA, Health Canada or the EMA have conducted a repeat inspection of Daewoong manufacturing facility per usual FDA Quality Review Practices to confirm continued compliance with cGMP regulations. A separate pre-licensure inspection may be required for any BLA we submit for any of our product candidates. Should the repeat inspection find serious deviation from cGMP manufacturing regulations, or repeated observations, Daewoong may be required to expend significant time and resources to correct any observations, which could cause delays and adversely affect availability of drug product to support our R&D operations. For example, the FDA is permitted to deny entry of any imported product that “appears” to be adulterated or misbranded, meaning it does not actually need to be violative to be prohibited from entry, just that the FDA believes it might be violative. FDA-483 observations, particularly if eventually escalated into an FDA untitled or warning letter, could result in an import alert, which bans entry of a product into the United States until issues are resolved to the FDA’s satisfaction, and until the FDA has reinspected the facility to confirm all corrections have been implemented, which could potentially take a considerable amount of time. In addition, failure to have an observation-free inspection during a pre-approval inspection can result in delay or denial or FDA approval. Similar issues could occur in other jurisdictions as well.

Additionally, if Daewoong’s facility were to be damaged, destroyed or otherwise unable to operate or comply with regulatory requirements, whether due to earthquakes, fire, floods, hurricanes, storms, tornadoes, other natural disasters, employee malfeasance, terrorist acts, political unrest, power outages or otherwise, or if operations at the facility were disrupted for any other reason, such an event could negatively affect our ongoing preclinical studies and clinical studies and, if ABP-450 is approved, jeopardize Daewoong’s ability to manufacture ABP-450 as promptly as we or our customers expect or possibly at all. If an event occurred that prevented Daewoong from using all or a significant portion of its manufacturing facility due to damaged critical infrastructure, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for Daewoong to supply enough ABP-450 to continue our business for a substantial period of time.

A material breach by us of the terms of our license and settlement agreement with Medytox, Inc. could have a material adverse effect on our business.

In May 2021, Medytox, Inc., or Medytox, brought a case against Old AEON in the United States District Court for the Central District of California, or the Medytox Litigation, alleging, among other things, that Daewoong stole Medytox’s botulinum toxin bacterial strain, or the BTX strain, and misappropriated certain trade secrets of Medytox, including the process used to manufacture ABP-450 using the BTX strain, and that our and Daewoong’s activities conducted in the United States gave rise to liability for misappropriation of trade secrets. Medytox sought, among other things, (i) actual, consequential and punitive damages, (ii) a reasonable royalty, as appropriate, (iii) disgorgement of any proceeds or profits, (iv) injunctive relief prohibiting us from using Medytox’s trade secrets to manufacture, offer to sell, or sell therapeutic BTX products, including ABP-450, and (v) attorneys’ fees and costs.

The Medytox Litigation was another step in an ongoing dispute involving Medytox and Allergan, on the one side, and Evolus, Daewoong and us on the other side. In June 2017, Medytox brought a civil lawsuit of a similar nature against Evolus, Daewoong and us in the Superior Court of the State of California, which we refer to as the Superior Court Litigation, and a separate lawsuit in October 2017 against Daewoong in South Korea, which we refer to as the Korea Litigation. The lawsuit filed in the Superior Court of the State of California alleged claims substantially similar to the Medytox Litigation and was subsequently stayed on grounds of forum non conveniens, because the underlying facts that gave rise to the complaint occurred in South Korea, among other reasons. We

27

Table of Contents

are not a party to the Korea Litigation. In April 2018, the Superior Court of the State of California dismissed Medytox’s suit against Daewoong without prejudice on the basis that Medytox had brought a substantially similar proceeding against Daewoong in South Korea, and continued a stay of the case as to us and Evolus. In February 2021, the Superior Court of the State of California dismissed Medytox’s suit against us without prejudice, following Medytox’s filing of a notice of settlement of the case based on a settlement it entered with Evolus.

Additionally, in January 2019, Allergan and Medytox filed a complaint against Daewoong and Evolus with the United States International Trade Commission, or the United States ITC, alleging that the BTX strain used in Evolus’ Jeuveau product is manufactured based on misappropriated trade secrets of Medytox and therefore its importation is an unfair act. The Administrative Law Judge issued a final determination in December 2020. The final determination concluded that a violation of Section 337 of the Tariff Act of 1930 had occurred, and the United States ITC issued a limited exclusion order forbidding entry of Jeuveau into the United States for 21 months and a cease and desist order prohibiting Daewoong and Evolus from engaging in the importations, sale for importation, marketing, distribution, offering for sale, the sale after the importation of, or other transfers of Jeuveau within the United States for 21 months. The 21-month ban was stayed as a result of a settlement agreement between Evolus and Medytox in February 2021.

Effective June 21, 2021, we entered into a settlement and license agreement with Medytox, or the Medytox Settlement Agreement, pursuant to which, among other things, Medytox agreed (a) to dismiss all claims against us in the Medytox Litigation, (b) to pursue dismissal of the appeals related to the December 2020 final determination of the United States ITC and agreed that as a result of such dismissal the final determination would be vacated, (c) to file appropriate documents in the Korea Litigation and related actions in support of the terms of the settlement, and (d) not to revive or otherwise pursue the Superior Court Litigation with respect to us. In addition, Medytox granted us a non-exclusive, royalty bearing license to Medytox’s botulinum toxin strain and specific trade secrets alleged to have been misappropriated in the litigation to commercialize and manufacture specific botulinum neurotoxin products including ABP-450 worldwide, with the exception of South Korea. In exchange for the license, we issued Medytox 26,680,511 shares of Old AEON common stock, par value $0.0001 per share, and agreed to pay Medytox single-digit royalties on the net sales of licensed products for 15 years following our first $1.0 million in commercial sales of neurotoxin products.

Medytox can terminate the Medytox Settlement Agreement if we materially breach any material provision of the agreement, either immediately upon written notice if the breach is incurable or after 60 days if capable of remedy. Additionally, Medytox may terminate the Medytox Settlement Agreement with 15 days of written notice if we or our affiliates or sublicensees challenge the validity, enforceability, scope, or protected status of Medytox’s botulinum strain and specific trade secrets alleged to have been misappropriated in the litigation. If the Medytox Settlement Agreement were terminated, Medytox would be able to revive the Medytox Litigation and other claims against us, and may seek an injunction or other ruling against us in the Korea Litigation, any one of which could result in us losing access to ABP-450 and the manufacturing process and require us to negotiate a new license with Medytox for continued access to ABP-450. We may not be able to successfully negotiate such license on terms acceptable to us or at all. If we are unable to license ABP-450, we may not be able to find a replacement product candidate on a timeline favorable to us, if at all, without expending significant resources and being required to seek additional regulatory approvals, which would be uncertain, time consuming and costly.

We rely, and will continue to rely, on third parties and consultants to conduct all of our preclinical studies and clinical studies. If these third parties or consultants do not successfully carry out their contractual duties or meet expected deadlines, we may be unable to obtain regulatory approval for ABP-450.

We do not currently have the ability to independently conduct any preclinical studies or clinical studies.

We rely, and will continue to rely, on medical institutions, clinical investigators, contract laboratories, collaborative partners and other third parties, such as CROs, to conduct preclinical studies and clinical studies on ABP-450. The third parties with whom we currently or may in the future contract for execution of any of our preclinical studies and clinical studies play a significant role in the conduct of these studies and the subsequent collection and analysis of data. However, these third parties are not our employees, and except for contractual duties and obligations, we have limited ability to control the amount or timing of resources that they devote to any of our current or future programs. Although we rely on these third parties to conduct our preclinical studies and clinical studies, we remain responsible for ensuring that each of our preclinical studies and clinical studies is conducted in accordance with the investigational plan and protocol. Moreover, the FDA and other similar regulatory authorities require us to observe both good laboratory practices, or GLP, and animal welfare requirements for preclinical studies, and to comply with GCPs for conducting,

28

Table of Contents

monitoring, recording and reporting the results of clinical studies to ensure that the data and results are scientifically credible and accurate, and that the study subjects are adequately informed of the potential risks of participating in clinical studies. We also rely, and will continue to rely, on consultants to assist in the execution, including data collection and analysis, of any of our future clinical studies.

In addition, the execution of preclinical studies and clinical studies, and the subsequent compilation and analysis of the data produced, requires coordination among various parties. In order for these functions to be carried out effectively and efficiently, it is imperative that these parties communicate and coordinate with one another. Moreover, these third parties may also have relationships with other commercial entities, some of which may compete with us. If the third parties or consultants conducting our clinical studies do not perform their contractual duties or obligations, experience work stoppages, do not meet expected deadlines, terminate their agreements with us or need to be replaced, or if the quality or accuracy of the preclinical or clinical data they obtain is compromised due to the failure to adhere to GLPs, or our clinical study protocols or GCPs, or for any other reason, we may need to conduct additional clinical studies or enter into new arrangements with alternative third parties, which could be difficult, costly or impossible, and our preclinical studies and clinical studies may be extended, delayed or terminated or may need to be repeated. Further, any noncompliance that results in data integrity issues could put any regulatory approval we receive at risk of withdrawal, and could subject us to regulatory sanctions due to failure to adequately oversee the third parties we rely upon. If any of the foregoing were to occur, we may not be able to obtain, or may be delayed in obtaining, regulatory approval for and will not be able to, or may be delayed in our efforts to, successfully commercialize ABP-450 in any of our proposed therapeutic indications.

The COVID-19 pandemic has had, and may continue to have, an adverse effect on our operations, as well as the business or operations of our manufacturers, CROs or other third parties with whom we conduct business.

Our business has been and could continue to be adversely affected by the evolving COVID-19 pandemic. As a result of COVID-19, we may experience ongoing disruptions that could severely impact our business, preclinical studies and clinical studies.

Our clinical studies have been, and may in the future be, affected by the COVID-19 pandemic. For example, if patient enrollment is delayed for an extended period of time, our ongoing and planned clinical studies could be delayed or otherwise adversely affected. Similarly, our ability to recruit and retain principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19, may be adversely impacted. The extent to which the COVID-19 pandemic may impact our business, preclinical studies and clinical studies will depend on future developments, which are uncertain and cannot be predicted with confidence. There could be, and has been, a significant disruption of global financial markets, which could reduce our ability to access capital, which could in the future negatively affect our liquidity and financial position.

In addition, to the extent the ongoing COVID-19 pandemic adversely affects our business and results of operations, it may also have the effect of heightening many of the other risks and uncertainties described in this “Risk Factors” section.

We may use third-party collaborators to help us develop, validate or commercialize any new products, and our ability to commercialize such products could be impaired or delayed if these collaborations are unsuccessful.

We may license or selectively pursue strategic collaborations for the development, validation and commercialization of ABP-450 in any current or future proposed therapeutic indications. In any third-party collaboration, we would be dependent upon the success of the collaborators in performing their responsibilities and their continued cooperation, and we would have limited control over the amount and timing of resources and effort that our collaborators would dedicate to the development or commercialization of our product candidates. Our collaborators may not cooperate with us or perform their obligations under our agreements with them at all or as expected. Our collaborators may choose to pursue alternative technologies in preference to those being developed in collaboration with us. The development, validation and commercialization of our current and future product candidates may be delayed if collaborators fail to conduct their responsibilities in a timely manner or in accordance with applicable regulatory requirements or if they breach or terminate their collaboration agreements with us. Our collaborators could also independently develop, or develop with third parties, products that compete directly or indirectly with our product candidates, fail to properly maintain or defend our intellectual property rights or infringe the intellectual property rights of third parties, exposing us to litigation. Disputes with our collaborators could also impair our reputation or result in development and commercialization delays, decreased revenues and could cause litigation expenses.

29

Table of Contents

In addition, we may face significant competition in seeking appropriate collaborators. Whether we reach a definitive agreement for a collaboration will depend, among other things, upon our assessment of the collaborator’s resources and expertise, the terms and conditions of the proposed collaboration and the proposed collaborator’s evaluation of a number of factors. Those factors may include the design or results of clinical studies, the likelihood of approval by the FDA or similar regulatory authorities outside the United States, the potential market for ABP-450 or our future product candidates in our proposed therapeutic indications, the costs and complexities of manufacturing and delivering ABP-450 or our future product candidates to patients, the potential of competing products, the existence of uncertainty with respect to our ownership of technology, which can exist if there is a challenge to such ownership without regard to the merits of the challenge, and industry and market conditions generally. The collaborator may also consider alternative product candidates or technologies for similar indications that may be available to collaborate on and whether such a collaboration could be more attractive than the one with us for our product candidate. Collaborations are complex and time-consuming to negotiate and document.

We may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of ABP-450 or our future product candidates in any of our proposed therapeutic indications, reduce or delay development programs, delay potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or commercialization activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop and commercialize ABP-450 or our future product candidates in any of our proposed therapeutic indications or bring them to market and generate revenue.

Risks Related to Intellectual Property

If we or any of our current or future licensors, including Daewoong, are unable to maintain, obtain or protect intellectual property rights related to ABP-450 and any future product candidates we may develop, or if the scope of any protection obtained is not sufficiently broad, we may not be able to compete effectively in our market.

Our success depends, in large part, on our ability to seek, obtain and maintain intellectual property protection in the United States and other countries with respect to our technologies. We and Daewoong currently rely upon a combination of trademarks, trade secret protection, confidentiality agreements and proprietary know-how. Additionally, Daewoong has obtained a United States patent related to its proprietary botulinum toxin manufacturing process. We also intend to protect our proprietary technology and methods by, among other things, filing for and obtaining United States and foreign patent applications related to our proprietary technology, inventions, methods of use, and improvements that are important to the development and implementation of our business. However, due to existing patent eligibility laws, we do not expect to obtain patent protection for the composition of matter for botulinum toxin, as it is produced by Clostridium botulinum, a gram-positive, rod-shaped, anaerobic, spore-forming, motile bacterium with the ability to produce the botulinum toxin. Although we do not own any issued patents, we have filed certain provisional and non-provisional patent applications with the United States Patent and Trademark Office, or USPTO, related to certain novel and proprietary methods of utilizing ABP-450 for therapeutic purposes. These patent applications may fail to result in any issued patents with claims that cover ABP-450 in any currently proposed or future therapeutic indications, in the United States or in other foreign countries, and the patents, if issued, may be declared invalid or unenforceable.

The patent prosecution process is expensive, time-consuming and complex, and we may not be able to file, prosecute, maintain, enforce or license all necessary or desirable patent applications at a reasonable cost or in a timely manner. We may not be able to obtain or maintain patent applications and patents due to the subject matter claimed in such patent applications and patents being in disclosures in the public domain. In addition, it is possible that we will fail to identify patentable aspects of our R&D output before it is too late to obtain patent protection. Although we enter into confidentiality agreements with parties who have access to confidential or patentable aspects of our R&D output, such as our employees and third-party consultants, any of these parties may breach these agreements and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. Consequently, we may not be able to prevent any third party from using any of our technology that is in the public domain to compete with ABP-450 and any future product candidates.

Other parties have developed technologies that may be related to or competitive to our own technologies and such parties may have filed or may file patent applications, or may have obtained or may obtain patents, claiming inventions that may overlap or conflict with those claimed in our patent applications or any future issued patents. We may not be aware of all third-party intellectual

30

Table of Contents

property rights potentially relating to ABP-450 and any future product candidates. Publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the United States and in other jurisdictions are typically not published until 18 months after filing, or, in some cases, not at all. Therefore, we cannot know with certainty whether the inventors of our pending patent applications were the first to make the inventions claimed in those patent applications, or that they were the first to file for patent protection of such inventions. If a third party can establish that we were not the first to make or the first to file for patent protection of such inventions, our patent applications may not issue and any patents, if issued, may be challenged and invalidated or rendered unenforceable.

Even in the event our non-provisional patent applications are granted, or if we in-license issued patent rights from third parties, the issuance of a patent is not conclusive as to its inventorship, scope, validity or enforceability and any such patents may be challenged in courts or patent offices in the United States and abroad and later declared invalid or unenforceable. For example, we may be subject to a third-party submission of prior art to the USPTO challenging the validity of one or more claims of any such patents. A third party may also claim that any such patents are invalid or unenforceable in a litigation. The outcome following legal assertions of invalidity and unenforceability is unpredictable. An adverse result in any legal proceeding could put any such patents at risk of being invalidated or interpreted narrowly and could allow third parties to commercialize our products and compete directly with us, without payment to us, or result in our inability to manufacture or commercialize products without infringing third-party patent rights. In addition, we may become involved in derivation, reexamination, inter partes review, post-grant review or interference proceedings and other similar proceedings in foreign jurisdictions (e.g., opposition proceedings) challenging the validity, priority or other features of patentability of any such patent rights. Challenges to our patent rights may result in loss of patent rights, exclusivity, or in patent claims being narrowed, invalidated, or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit the scope and duration of the patent protection of ABP-450 or future product candidates. Such challenges also may result in substantial cost and require significant time from our scientists and management, even if the eventual outcome is favorable to us. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

Furthermore, patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after it is filed. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited. Given the amount of time required for the development, testing and regulatory review of botulinum toxins, patents protecting such product candidates might expire before or shortly after they are commercialized. As a result, our patent applications, even if issued, may not provide us with adequate and continuing patent protection sufficient to exclude others from commercializing products similar to ABP-450 or future product candidates, including biosimilar versions of such products.

Even if they are unchallenged, our pending patent applications, if issued, may not provide us with any meaningful protection or prevent competitors from designing around our patent claims to circumvent our patents by developing similar or alternative technologies or therapeutics in a non-infringing manner. If the patent protection provided by our patent applications, if issued, is not sufficiently broad to impede such competition, our ability to successfully commercialize ABP-450 and future product candidates could be negatively affected, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Under the Daewoong Agreement, we license the trademark for Nabota associated with ABP-450 from Daewoong; however, we may ultimately pursue alternative trademarks and branding for ABP-450. Our or Daewoong’s trade secrets and other confidential proprietary information and those of our future licensors could be disclosed or competitors could otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Further, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the United States. As a result, we or any of our current or future licensors may encounter significant problems in protecting and defending our or their intellectual property both in the United States and internationally. If we or any of our current or future licensors are unable to prevent material disclosure of the non-patented intellectual property related to ABP-450 to third parties, we may not be able to establish or maintain a competitive advantage in our market, which could adversely affect our business.

In addition to the protection afforded by patents, trademarks, confidentiality agreements and proprietary know-how, we may in the future rely upon in-licensed or acquired patents or proprietary technology for the development of ABP-450 in any currently proposed or future therapeutic indications. We may not be able to in-license third party patents necessary to commercialize ABP-450 on commercially reasonable terms, or at all, which could materially harm our business. Even if we are able to in-license any such necessary intellectual property, it could be on nonexclusive terms, thereby giving our competitors and other third parties access to the

31

Table of Contents

same intellectual property licensed to us, and it could require us to make substantial licensing and royalty payments. The licensing or acquisition of third-party intellectual property rights is a competitive area, and several more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. These established companies may have a competitive advantage over us due to their size, capital resources and greater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party intellectual property rights on terms that would allow us to make an appropriate return on our investment. If we are unable to successfully obtain rights to required third-party intellectual property or maintain the existing intellectual property rights we have licensed, we may be required to expend significant time and resources to redesign ABP-450 or future product candidates, or to develop or license replacement technology, all of which may not be feasible on a technical or commercial basis, and we may have to abandon development of ABP-450 or future product candidates which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Additionally, the strength of any patents that issue from our non-provisional patent applications or that we may in-license from third parties in the technology and healthcare fields involves complex legal and factual questions and has, in recent years, been the subject of much litigation. As a result, the issuance, scope, validity, enforceability and commercial value of any patent rights in such fields can be uncertain. Our pending patent applications and any patent applications that we may in-license may fail to result in issued patents with claims that cover ABP-450 in any currently proposed or future therapeutic indications, in the United States or in other foreign countries, and the issued patents that we may in-license may be declared invalid or unenforceable.

We are reliant on the ability of Daewoong, as the licensor of our only product candidate, to maintain its intellectual property and protect its intellectual property against misappropriation, infringement or other violation. We may not have primary control over Daewoong’s or our future licensors’ patent prosecution activities. Furthermore, we may not be allowed to comment on prosecution strategies, and patent applications currently being prosecuted may be abandoned by the patent owner without our knowledge or consent.

With respect to patents that are issued to our licensors, or patents that may issue on patent applications, third parties may challenge their validity, enforceability or scope, which may result in such patents being narrowed or invalidated. As a licensee, we are reliant on Daewoong and our future licensors to defend any third-party claims. Our licensors may not defend or prosecute such actions as vigorously or in the manner that we would have if entitled to do so, and we may be impacted by any judgment or settlement resulting from such actions. Also, a third party may challenge the validity of our in-licensing transactions. Furthermore, even if they are unchallenged, any of our future in-licensed patents and patent applications may not adequately protect the licensors or our intellectual property or prevent others from designing around their or our claims.

Third-party claims of intellectual property infringement, misappropriation or violation, or challenges related to the invalidity or unenforceability of any issued patents we may obtain or in-license may prevent or delay our development and commercialization efforts or otherwise adversely affect our results of operations.

Our commercial success depends in part on our and any of our future collaborators avoiding infringement, misappropriation or other violation of the intellectual property and related proprietary rights of third parties. Competitors and other entities that possess intellectual property rights related to the use of botulinum toxins in the fields of neurology and gastroenterology have developed large portfolios of patents and patent applications in fields relating to our business. In particular, there are patents held by third parties that relate to the treatment with botulinum toxin-based products. There may also be patent applications that have been filed but not published that, when issued as patents, could be asserted against us. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the technology, medical device and pharmaceutical industries, including patent infringement lawsuits, interferences, oppositions and inter partes reexamination proceedings before the USPTO. Numerous United States and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we plan to develop ABP-450. As the technology, medical device and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidate may be subject to claims of infringement of the patent rights of third parties, regardless of their merit.

There may be third-party patents or patent applications with claims to materials, methods of manufacture or methods for treatment related to the use or manufacture of ABP-450. Because patent applications can take many years to issue, may be confidential for 18 months or more after filing and can be revised before issuance, there may be currently pending patent applications that may later result in issued patents that ABP-450 or any future product candidates may infringe. It is difficult for industry participants, including

32

Table of Contents

us, to identify all third-party patent rights that may be relevant to ABP-450 and future product candidates because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the difficulty in assessing the meaning of patent claims. We may fail to identify relevant patents or patent applications or may identify pending patent applications of potential interest but incorrectly predict the likelihood that such patent applications may issue with claims of relevance to our technology or incorrectly conclude their invalidity or unenforceability. In addition, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover ABP-450 or future product candidates and third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents. Even if we believe claims brought against us are without merit, a court of competent jurisdiction could hold that these third-party patents are valid, enforceable and infringed. In order to successfully challenge the validity of any such United States patent in federal court, we would need to overcome a presumption of validity. As this burden is a high one requiring us to present clear and convincing evidence as to the invalidity of any such United States patent claim, there is no assurance that a court of competent jurisdiction would invalidate the claims of any such United States patent or find that ABP-450 or future product candidates did not infringe any such claims. If any third-party patents were held by a court of competent jurisdiction to cover the manufacturing process of ABP-450, the holders of any such patents may be able to block our ability to commercialize ABP-450 in any proposed therapeutic indication unless we obtain a license under the applicable patents or until such patents expire. Similarly, if any third-party patent were held by a court of competent jurisdiction to cover aspects of our methods of use, the holders of any such patent may be able to block our ability to develop and commercialize ABP-450 unless we obtain a license or until such patent expires. In either case, such a license may not be available on commercially reasonable terms or at all.

In addition to claims of patent infringement, third parties may bring claims against us asserting misappropriation or other violations of proprietary technology or other information in the development, manufacture and commercialization of ABP-450. Defense of such a claim would require dedicated time and resources, which time and resources could otherwise be used by us toward the maintenance of our own intellectual property and the development and commercialization of ABP-450 in any current or future proposed therapeutic indication or for operational upkeep and manufacturing of our product. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our Common Stock. We have been, and may in the future become, party to, or be threatened with, adversarial proceedings or litigation where our competitors or other third parties may assert claims against us, alleging that our therapeutics, manufacturing methods, formulations, administration methods or delivery devices infringe, misappropriate or otherwise violate their intellectual property rights, including patents and trade secrets. For example, in the past, Medytox asserted that we and Daewoong were employing their proprietary technology without authorization, and other third parties may make similar assertions about us or any of our current or future licensors, including Daewoong, in the future. For more information regarding our litigation with Medytox, please see “Risk Factors — Risks Related to Our Reliance on Third Parties — A material breach by us of the terms of our license and settlement agreement with Medytox, Inc. could have a material adverse effect on our business.”

Likewise, any patents that may issue from our pending patent applications or any future in-licensed patents and pending patent applications may also be subject to priority, validity, inventorship and enforceability disputes in court or before administrative bodies in the United States or abroad. If we or any of our licensors are unsuccessful in any of these proceedings, such patents and patent applications may be narrowed, invalidated or held unenforceable, we may be required to obtain licenses from third parties, which may not be available on commercially reasonable terms or at all, or we may be required to cease the development, manufacture and commercialization of ABP-450 or future product candidates. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

Parties making claims against us or any of our current or future licensors may request and obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize ABP-450. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business which time and resources could otherwise be used by us toward the maintenance of our own intellectual property and the development and commercialization of ABP-450 in any current or future proposed therapeutic indication or for operational upkeep and manufacturing of our product. In the event of a successful claim of infringement, misappropriation or other violation of a third party’s intellectual property, we or any of our current or future licensors may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties which may not be commercially available, or pay royalties or redesign our infringing products or manufacturing processes, which may be impossible or require substantial time and monetary expenditure. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research, manufacture clinical study supplies or allow commercialization of ABP-450 in any current or future proposed therapeutic

33

Table of Contents

indication. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In that event, we would be unable to further develop and commercialize ABP-450 in one or more of our proposed therapeutic indications, which could harm our business significantly. Similarly, third-party patents could exist that might be enforced against our products, resulting in either an injunction prohibiting our sales, or with respect to our sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties.

We may become involved in lawsuits to protect or enforce our intellectual property or the patents and other intellectual property of our licensors, which could be expensive and time-consuming.

Competitors may infringe our intellectual property, including any future patents we may acquire, or any future patents or other intellectual property licensed to us by our licensors, including Daewoong. As a result, we or any of our current or future licensors may be required to file infringement claims to stop third-party infringement or unauthorized use. Even if resolved in our favor, this can be unpredictable, expensive, particularly for a company of our size, and time-consuming and may cause us to incur significant expenses and distract our scientific and management personnel from their normal responsibilities. In addition, in an infringement proceeding, a court may decide that a patent of ours or any of our current or future licensors is not valid or is unenforceable, or may refuse to stop the other party from using the technology at issue on the grounds that our patent claims do not cover its technology or that the factors necessary to grant an injunction against an infringer are not satisfied.

An adverse determination of any litigation or other proceedings could put one or more of such patents at risk of being invalidated or interpreted narrowly. Interference, derivation or other proceedings brought at the USPTO may be necessary to determine the priority or patentability of inventions with respect to any of our future patent applications or those of our licensors or collaborators. Litigation or USPTO proceedings brought by us or any of our current or future licensors may fail or may be invoked against us or our licensors by third parties. Even if we are successful, domestic or foreign litigation or USPTO or foreign patent office proceedings may result in substantial costs and distraction to our management or the management of any of our current or future licensors, including Daewoong. We may not be able, alone or with any of our current or future licensors or collaborators, to prevent misappropriation of our proprietary rights, particularly in countries where the laws may not protect such rights as fully as in the United States.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation or other proceedings, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation or proceedings. In addition, during the course of this kind of litigation or proceedings, there could be public announcements of the results of hearings, motions or other interim proceedings or developments or public access to related documents. If securities analysts or investors perceive these results to be negative, the market price for our Common Stock could be significantly harmed. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities.

Most of our competitors are larger than we are and have substantially greater resources. They are, therefore, likely to be able to sustain the costs of complex patent litigation or other intellectual property proceedings longer than we could. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. In addition, the uncertainties associated with the initiation and continuation of litigation or other intellectual property proceedings could compromise our ability to raise the funds necessary to continue our clinical studies, continue our internal research programs, or in-license needed technology, or otherwise have a material adverse effect on our business, financial condition, results of operations and prospects.

Our rights to develop and commercialize ABP-450 and future product candidates are subject, in part, to the terms and conditions of licenses granted to us by others, including Daewoong. If we fail to comply with our obligations in the agreements under which we license intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we could lose license rights that are important to our business.

We are heavily reliant upon our license from Daewoong to certain proprietary technology that is important or necessary to the development of ABP-450 and future product candidates. Additionally, further development and commercialization of ABP-450 and future product candidates may require us to enter into additional license or collaboration agreements. For more information regarding our reliance on Daewoong and future collaboration agreements, please see “Risk Factors — Reliance on Third Parties.”

Our current and any future licenses may not provide us with exclusive rights to use the licensed intellectual property and technology or may not provide us with exclusive rights to use such intellectual property and technology in all relevant fields of use

34

Table of Contents

and in all territories in which we may wish to develop or commercialize ABP-450 and future product candidates. As a result, we may not be able to prevent competitors or other third parties from developing and commercializing competitive products, including in territories covered by our licenses.

In some circumstances, we may not have the right to control the maintenance, prosecution, preparation, filing, enforcement, defense or litigation of patents and patent applications that we license from or license to third parties and are reliant on our licensors or licensees to do so. We thus cannot be certain that activities such as patent maintenance and prosecution by our licensors have been or will be conducted consistent with our best interests or in compliance with applicable laws and regulations, or will result in valid and enforceable patents and other intellectual property rights. It is possible that our licensors’ infringement proceedings or defense activities may be less vigorous than had we conducted them ourselves or may not be conducted in accordance with our best interests. If our licensors fail to maintain such patents or patent applications, or lose rights to those patents or patent applications, the rights we have licensed may be reduced or eliminated, and our right to develop and commercialize future product candidates that are the subject of such licensed rights and our right to exclude third parties from commercializing competing products could be adversely affected. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

In spite of our efforts, our current and future licensors might conclude that we have materially breached our obligations under our license agreements and might therefore terminate such license agreements, thereby removing or limiting our ability to develop and commercialize products and technology covered by these license agreements. Disputes may arise with respect to our current or future licensing agreements, including disputes relating to:

For example, the Daewoong Agreement does not contain provisions regarding the ownership of any intellectual property that results from inventions or improvements related to ABP-450. There could be disputes in the future related to the inventorship or ownership of inventions and know-how resulting from our improvements to ABP-450 and future related product candidates, although we believe we are the sole owner of our intellectual property and have developed it independently of Daewoong.

If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize ABP-450 and future product candidates. If our licenses are terminated, we may lose our rights to develop and market ABP-450 and future product candidates, lose patent protection for ABP-450 and future product candidates, experience significant delays in the development and commercialization of ABP-450 and future product candidates, or incur liability for damages. In addition, we may seek to obtain additional licenses from our licensors and, in connection with obtaining such licenses, we may agree to amend our existing licenses in a manner that may be more favorable to the licensors, including by agreeing to terms that could enable third parties, including our competitors, to receive licenses to a portion of the intellectual property that is subject to our existing licenses and to compete with ABP-450 and future product candidates.

Furthermore, if the Daewoong Agreement or any future licenses are terminated, or if the underlying patents or other intellectual property rights fail to provide the intended exclusivity, competitors or other third parties would have the freedom to seek regulatory

35

Table of Contents

approval of, and to market, products identical or competitive to ours and we may be required to cease our development and commercialization of ABP-450 and future product candidates. Moreover, if disputes over intellectual property that we license prevent or impair our ability to maintain other licensing arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize ABP-450 and future product candidates. In addition, certain of these license agreements may not be assignable by us without the consent of the respective licensor, which may have an adverse effect on our ability to engage in certain transactions. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our license agreements are, and future license agreements are likely to be, complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents relating to ABP-450 and any future product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States; a patent owner may have limited remedies, and in some cases foreign authorities may even force us to grant a compulsory license to competitors or other third parties. As such, we or our licensors may not be able to obtain patent protection for ABP-450 and future product candidates outside the United States. Consequently, we may not be able to prevent third parties from using our inventions in all countries outside the United States or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and further, may export otherwise infringing products to territories where we have patent protection, but enforcement is not as strong as that in the United States. These products may compete with our products and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biopharmaceuticals, which could make it difficult for us to stop the infringement any of our patents that may issue from our pending patent applications, or the marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly, could put our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We or our licensors may not prevail in any lawsuits that we or our licensors initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

In addition, our ability to protect and enforce our intellectual property rights may be adversely affected by unforeseen changes in domestic and foreign intellectual property laws.

If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patent protection for our product candidates, including ABP-450, we and our licensors also rely on trade secrets protection to protect our and their unpatented know-how, technology and other proprietary information, in order to maintain our and their competitive positions.

We and our licensors seek to protect our trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, collaborators, consultants, advisors and other third parties. We have entered into invention assignment agreements with our current employees. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies

36

Table of Contents

for such breaches. Monitoring unauthorized uses and disclosures is difficult, and we do not know whether the steps we or our licensors have taken to protect our respective proprietary technologies will be effective.

Additionally, we cannot guarantee that we or our licensors have entered into such agreements with each party that may have or has had access to our respective trade secrets. We also seek to preserve the integrity and confidentiality of our data and trade secrets by taking security measures with respect to our information technology systems; however, our or our licensors’ systems and security measures may be breached, and we may not have adequate remedies for any breach. As a result, we or our licensors could lose our trade secrets and third parties could use our or our licensors’ trade secrets to compete with ABP-450 or future product candidates.

Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. Competitors or third parties could purchase ABP-450 and future product candidates and attempt to replicate or reverse engineer some or all of the competitive advantages we derive from our development efforts, willfully infringe our intellectual property rights, design around our protected technology or develop their own competitive technologies that fall outside the scope of our intellectual property rights. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or third party, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed by a competitor, our competitive position would be harmed.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed confidential information of third parties or asserting ownership of what we regard as our own intellectual property.

We employ individuals who were previously employed at other pharmaceutical companies including certain of our anticipated competitors. We may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed confidential information, including intellectual property and other proprietary information, of our employees’ former employers or other third parties. Litigation may be necessary to defend against these claims. We may not be successful in defending these claims, and even if we are successful, litigation could result in substantial cost and be a distraction to our management and other employees. Any litigation or the threat thereof may adversely affect our ability to hire or retain employees. A loss of key personnel or their work product could diminish or prevent our ability to commercialize ABP-450, which could have an adverse effect on our business, results of operations and financial condition.

In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may also be subject to claims that former employers or other third parties have an ownership interest in our patents or other intellectual property. Moreover, even when we obtain agreements assigning intellectual property to us, the assignment of intellectual property rights may not be self-executing or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Furthermore, individuals executing agreements with us may have preexisting or competing obligations to a third party, such as an academic institution, and thus an agreement with us may be ineffective in perfecting ownership of inventions developed by that individual. We or our licensors may in the future be subject to claims by former employees, consultants or other third parties asserting an ownership right in our owned or licensed patents or patent applications. An adverse determination in any such submission or proceeding may result in loss of exclusivity or freedom to operate or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar technology and therapeutics, without payment to us, or could limit the duration of any patent protection covering ABP-450 and future product candidates. Disputes about the ownership of intellectual property may have a material adverse effect on our business, financial condition, results of operations and prospects.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.

Although we have filed applications to register trademarks in the United States, we currently do not own any registered trademarks and our current and future trademark applications in the United States and in foreign jurisdictions may not be allowed or may subsequently be opposed. Further, our unregistered or future registered trademarks or trade names may be challenged, infringed, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition by potential partners or customers in our markets of interest. At

37

Table of Contents

times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected.

Third parties may assert that we are using trademarks or trade names that are confusingly similar to their marks. If any third-party were able to establish that our trademarks or trade names were infringing their marks, that third-party may be able to block our ability to use the infringing trademark or trade name. In addition, if a third-party were to bring such a claim, we would be required to dedicate time and resources to fight the claim, which time and resources could otherwise be used toward the maintenance of our own intellectual property.

Parties making claims against us may request and obtain injunctive or other equitable relief, which could prevent our ability to use the subject trademarks or trade names. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee and management resources from our business, and their time and resources could otherwise be used toward the maintenance of our own intellectual property and may otherwise be expensive and time-consuming, particularly for a company of our size. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement. We may be required to re-brand one or more of our products or services offered under the infringing trademark or trade name, which may require substantial time and monetary expenditure. Third parties could claim senior rights in marks which might be enforced against our use of trademarks or trade names, resulting in an injunction prohibiting our sales under those trademarks or trade names.

Our efforts to enforce or protect our proprietary rights related to trademarks may be ineffective and could result in substantial costs and diversion of resources. Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

Intellectual property rights do not necessarily address all potential threats.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

Any of the foregoing could have a material adverse effect on our business, financial condition, results of operations and prospects.

Risks Related to Government Regulation

Our business and products are subject to extensive government regulation.

We are subject to extensive, complex, costly and evolving regulation by federal and state governmental authorities in the United States, the European Union, Canada and other countries, principally by the FDA, the EMA, Health Canada and other similar regulatory authorities. Daewoong is also subject to extensive regulation by the FDA and the South Korean regulatory authorities as well as other regulatory authorities. Our failure to comply with all applicable regulatory requirements, or Daewoong’s or any future collaborator’s failure to comply with applicable regulatory requirements, including those promulgated under the Federal Food, Drug, and Cosmetic Act, the Public Health Service Act, and other laws may subject us to operating restrictions and criminal prosecution, monetary penalties and other enforcement or administrative actions, including sanctions, warning letters, import alerts, product seizures, recalls, fines, injunctions, suspension, revocation of approvals, or exclusion from future participation in the Medicare and Medicaid programs.

In the event our products receive regulatory approval, we and our direct and indirect suppliers, including Daewoong, will remain subject to the periodic inspection of our plants and facilities, review of production processes, and testing of our products to confirm that we are in compliance with all applicable regulations. Adverse findings during regulatory inspections may result in requirements that we implement REMS programs, requirements that we complete government mandated clinical studies, and government enforcement actions, including those relating to labeling, advertising, marketing and promotion, as well as regulations governing manufacturing controls.

If we experience delays in obtaining approval or if we fail to obtain approval of ABP-450 in any of our proposed therapeutic indications, the commercial prospects for ABP-450 may be harmed and our ability to generate revenue will be materially impaired.

In addition, in the course of our activities we may collect information from clinical study subjects or other individuals that subjects us to a variety of rapidly evolving laws regarding privacy, data protection and data security, including those related to the collection, storage, handling, use, disclosure, transfer and security of personal data. Data breaches or other violations of these laws could subject our business to significant penalties and reputational harm. For more information on data security and privacy, see “Risk Factors — Risks Related to Government Regulation — We are subject to stringent and often unsettled privacy laws, information security laws, regulations, policies and contractual obligations related to data privacy and security and changes in such laws, regulations, policies and contractual obligations could adversely affect our business.”

If we fail to obtain regulatory approvals in foreign jurisdictions for ABP-450, we will be unable to market our products outside of the United States.

In addition to regulations in the United States, we are and will be subject to a variety of foreign regulations governing manufacturing, clinical studies, commercial sales and distribution of our future products. Whether or not we obtain FDA approval for a product candidate, we must obtain approval of the product by the comparable regulatory authorities of foreign countries before commencing clinical studies or marketing in those countries. The approval procedures vary among countries and can involve additional clinical testing, and the time required to obtain approval may differ from that required to obtain FDA approval. Clinical studies conducted in one country may not be accepted by regulatory authorities in other countries. Approval by the FDA does not ensure approval by regulatory authorities in other countries, and approval by one or more foreign regulatory authorities does not

39

Table of Contents

ensure approval by regulatory authorities in other foreign countries or by the FDA. The foreign regulatory approval process may include all of the risks associated with obtaining FDA approval. We may not be able to file for regulatory approvals or to do so on a timely basis, and even if we do file, we may not receive necessary approvals to commercialize our products in markets outside of the United States.

The misuse or off-label use of our approved products, if any, may harm our reputation in the marketplace, result in injuries that lead to product liability suits or result in costly investigations, fines or sanctions by regulatory bodies if we are deemed to have engaged in the promotion of these uses, any of which could be costly to our business.

The FDA and other regulatory agencies strictly regulate the marketing and promotional claims that are made about pharmaceutical products. In particular, a product may not be promoted for uses or indications that are not specifically approved by the FDA, the EMA or other regulatory agencies as reflected in the product’s approved labeling. For example, if we receive marketing approval for ABP-450 in any therapeutic indication, physicians could use ABP-450 on their patients in a manner that is inconsistent with the approved label, such as for the treatment of other aesthetic or therapeutic indications for which other similar botulinum toxins are approved. Although ABP-450, if approved, will be similar to Jeuveau, we will not be able to market ABP-450 as being interchangeable with Jeuveau. If we are found to have promoted uses that are not part of ABP-450’s approved labeling, we may be subject to enforcement action from the FDA, the EMA and other regulatory agencies, as applicable, and become subject to significant liability, which would materially harm our business. The federal government has levied large civil and criminal fines against companies for alleged improper promotion and has enjoined several companies from engaging in off-label promotion. If we become the target of such an investigation or prosecution based on our marketing and promotional practices, we could face similar sanctions, which would materially harm our business. In addition, management’s attention could be diverted from our business operations, significant legal expenses could be incurred, and our reputation could be damaged. The FDA has also required that companies enter into consent decrees or permanent injunctions under which specified promotional conduct is changed or curtailed in order to resolve FDA enforcement actions. If we are deemed by the FDA to have engaged in the promotion of our products for off-label use, we could be subject to FDA prohibitions or other restrictions on the sale or marketing of our products and other operations or significant fines and penalties, and the imposition of these sanctions could also affect our reputation and position within the industry. In addition, off-label promotion could expose us to liability under the FCA, as well as similar state laws.

Physicians may also misuse ABP-450, if approved, or use improper techniques, potentially leading to adverse results, side effects or injury, which may lead to product liability claims. If ABP-450 is misused or used with improper techniques or is determined to cause or contribute to patient harm, we may become subject to costly litigation by our customers or their patients. Product liability claims could divert management’s attention from our core business, be expensive to defend, result in sizable damage awards against us that may not be covered by insurance and subject us to negative publicity resulting in reduced sales of our products. Furthermore, the use of ABP-450, if approved, for indications other than those cleared by the FDA, may not effectively treat such conditions, which could harm our reputation in the marketplace among physicians and patients. Any of these events could harm our business and results of operations and cause the price of our Common Stock to decline.

Our relationships with healthcare providers and physicians and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.

We are subject to applicable fraud and abuse and other healthcare laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the FCA, which may constrain the business or financial arrangements and relationships through which we sell, market and distribute our products. In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the healthcare industry (e.g., healthcare providers, physicians and third party payors), are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commission(s), certain customer incentive programs and other business arrangements generally. We also may be subject to patient information and privacy and security regulation by both the federal government and the states and foreign jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws and regulations that may affect our ability to operate include, but are not limited to:

40

Table of Contents

41

Table of Contents

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulatory guidance. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies, healthcare providers and other third parties, including charitable foundations, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Responding to investigations can be time- and resource-consuming and can divert management’s attention from the business. Any such investigation or settlement could increase our costs or otherwise have an adverse effect on our business.

If our marketing or other arrangements were determined to violate anti-kickback or related laws, including the FCA or an all-payor law, then we could be subject to penalties, including administrative, civil and criminal penalties, damages, fines, disgorgement, the exclusion from participation in federal and state healthcare programs, individual imprisonment, reputational harm and the curtailment or restructuring of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws. Any action for violation of these laws, even if successfully defended, could cause us to incur significant legal expenses and divert management’s attention from the operation of the business. Prohibitions or restrictions on sales or withdrawal of future marketed products could materially affect our business in an adverse way. Efforts to ensure that our business arrangements will comply with applicable healthcare laws may involve substantial costs.

State and federal authorities have aggressively targeted pharmaceutical companies for alleged violations of these anti-fraud statutes, based on improper research or consulting contracts with doctors, certain marketing arrangements with pharmacies and other healthcare providers that rely on volume-based pricing, off-label marketing schemes, and other improper promotional practices. Companies targeted in such prosecutions have paid substantial fines, have been ordered to implement extensive corrective action plans, and have in many cases become subject to consent decrees severely restricting the manner in which they conduct their business, among other consequences. Additionally, federal and state regulators have brought criminal actions against individual employees responsible for alleged violations. If we become the target of such an investigation or prosecution based on our contractual relationships with providers or institutions or our marketing and promotional practices, we could face similar sanctions, which would materially harm our business.

Also, the FCPA and similar worldwide anti-bribery laws generally prohibit companies and their intermediaries from making improper payments to non-United States officials for the purpose of obtaining or retaining business. Our internal control policies and procedures may not protect us from reckless or negligent acts committed by our employees, future distributors, partners, collaborators or agents. Violations of these laws, or allegations of such violations, could result in fines, penalties or prosecution and have a negative impact on our business, results of operations and reputation.

Legislative or regulatory healthcare reforms in the United States and other countries may make it more difficult and costly for us to obtain regulatory clearance or approval of ABP-450 and to produce, market, and distribute our products after clearance or approval is obtained.

From time to time, legislation is drafted and introduced in the United States Congress or other countries that could significantly change the statutory provisions governing the regulatory clearance or approval, manufacture, and marketing of regulated products or the reimbursement thereof. In addition, regulations and guidance are often revised or reinterpreted by the FDA and other regulatory authorities in ways that may significantly affect our business and our products. Any new regulations, revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of ABP-450. Such changes could, among other things, require:

42

Table of Contents

Each of these would likely entail substantial time and cost and could materially harm our business and our financial results. In addition, delays in receipt of or failure to receive regulatory clearances or approvals for any future products would harm our business, financial condition, and results of operations.

Inadequate funding for the FDA, the SEC and other government agencies, including from government shut downs, or other disruptions to these agencies’ operations, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result. Disruptions at the FDA and other agencies may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund R&D activities, is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years the United States government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Since March 2020 when foreign and domestic inspections of facilities were largely placed on hold, the FDA has been working to resume routine surveillance, bioresearch monitoring and pre-approval inspections on a prioritized basis. The FDA has developed a rating system to assist in determining when and where it is safest to conduct prioritized domestic inspections. As of May 2021, certain inspections, such as foreign preapproval, surveillance, and for-cause inspections that are not deemed mission-critical, remain temporarily postponed. In April 2021, the FDA issued guidance for industry formally announcing plans to employ remote interactive evaluations, using risk management methods, to meet user fee commitments and goal dates and in May 2021 announced plans to continue progress toward resuming standard operational levels. In July 2022, the FDA released a draft guidance document on use of mandatory and voluntary Remote Regulatory Assessments, or RRAs, which, among other things, addressed the use of remote assessments as a means of reducing delays in approvals, but did not in any way commit the FDA to using RRAs in lieu of on-site inspections. Should the FDA determine that an inspection is necessary for approval and an inspection cannot be completed during the review cycle due to restrictions on travel, and the FDA does not determine a remote interactive evaluation to be adequate, the agency has stated that it generally intends to issue a complete response letter or defer action on the application until an inspection can be completed. In 2020, 2021 and 2022 a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in response to the COVID-19 pandemic and may experience delays in their regulatory activities. If a prolonged government shutdown or other disruption occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Future shutdowns or other disruptions could also affect other government agencies such as the SEC, whichh may also impact our business by delaying review of our public filings, to the extent such review is necessary, and our ability to access the public markets.

We are subject to stringent and often unsettled privacy laws, information security laws, regulations, policies and contractual obligations related to data privacy and security and changes in such laws, regulations, policies and contractual obligations could adversely affect our business.

We are subject to data privacy and protection laws and regulations that apply to the collection, transmission, storage and use of personally identifying information or personal data, which among other things, impose certain requirements relating to the privacy, security and transmission of personal information. The legislative and regulatory landscape for privacy and data protection continues to evolve in jurisdictions worldwide, and there has been an increasing focus on privacy and data protection issues with the potential to

affect our business. Failure to comply with any of these laws and regulations could result in enforcement action against us, including fines, imprisonment of company officials and public censure, claims for damages by affected individuals, damage to our reputation and loss of goodwill, any of which could have a material adverse effect on our business, financial condition, results of operations or prospects.

There are numerous United States federal and state laws and regulations relating to privacy and security of personal information. Data privacy remains an evolving landscape at both the domestic and international level, with new regulations coming into effect. For example, the State of California enacted the California Consumer Privacy Act of 2018, or CCPA, which went into effect on January 1, 2020 and requires companies that process information on California residents to make new disclosures to consumers about their data collection, use and sharing practices, allow consumers to opt out of certain data sharing with third parties and provide a new cause of action for data breaches. Additionally, California voters approved a new privacy law, the California Privacy Rights Act, or CPRA, in the November 3, 2020 election. Effective starting on January 1, 2023, the CPRA significantly modifies the CCPA, including by expanding consumers’ rights with respect to certain sensitive personal information. The CPRA also created a new state agency that is vested with authority to implement and enforce the CCPA and the CPRA. New legislation proposed or enacted in various other states will continue to shape the data privacy environment nationally. Certain state laws may be more stringent or broader in scope, or offer greater individual rights, with respect to confidential, sensitive and personal information than federal, international or other state laws, and such laws may differ from each other, which may complicate compliance efforts.

In addition, all 50 states and the District of Columbia have enacted breach notification laws that may require us to notify patients, employees or regulators in the event of unauthorized access to or disclosure of personal or confidential information experienced by us or our service providers. These laws are not consistent, and compliance in the event of a widespread data breach is difficult and may be costly. Moreover, states have been frequently amending existing laws, requiring attention to changing regulatory requirements. We also may be contractually required to notify patients or other counterparties of a security breach.

Although we may have contractual protections with our service providers, any actual or perceived security breach could harm our reputation and brand, expose us to potential liability or require us to expend significant resources on data security and in responding to any such actual or perceived breach. Any contractual protections we may have from our service providers may not be sufficient to adequately protect us from any such liabilities and losses, and we may be unable to enforce any such contractual protections.

In addition, the GDPR became applicable on May 25, 2018 in respect of processing operations carried out in the context of the activities of an establishment in the European Economic Area, or EEA, and any processing relating to the offering of goods or services to individuals in the EEA and/or the monitoring of their behavior in the EEA.

While we do not at this time collect, store, use or process data on behalf of existing customers or for anyone residing in the United Kingdom or Europe, if we do so in the future, we will be subject to the rigorous and time-intensive policies of the GDPR. There is no assurance that our own limited privacy and security-related safeguards will protect us from all risks associated with data privacy and information security.

Risks Related to Being a Public Company

The price of our Common Stock may be volatile.

The price of our Common Stock has been and is likely to continue to be volatile. The market price for our Common Stock may be influenced by many factors, including the other risks described in this section of the prospectus entitled “Risk Factors” and the following:

Table of Contents

In addition, the stock markets in general, and the markets for SPAC post-business combination businesses, pharmaceutical, biopharmaceutical and biotechnology stocks in particular, have experienced extreme volatility, including since the Closing. This volatility can often be unrelated to the operating performance of the underlying business. These broad market and industry factors may seriously harm the market price of our Common Stock, regardless of AEON’s operating performance.

We may incur significant costs from class action litigation due to the expected stock volatility.

The price of Common Stock may fluctuate for many reasons, including as a result of public announcements regarding the progress of development efforts for our main product candidate, ABP-450, the development efforts of competitors, the addition or departure of key personnel, variations in quarterly operating results and changes in market valuations of biopharmaceutical and biotechnology companies. This risk is especially relevant to us because biopharmaceutical and biotechnology companies have experienced significant stock price volatility in recent years, including since the Closing. In addition, recently there has been significant stock price volatility involving the shares of companies that have recently completed a business combination with a SPAC. When the market price of a stock has been volatile as our Common Stock’s price may be, holders of that stock have occasionally brought securities class action litigation against the company that issued the stock. Additionally, there has recently been a general increase in litigation against companies that have recently completed a business combination with a SPAC alleging fraud and other claims based on inaccurate or misleading disclosures. If any of our stockholders were to bring a lawsuit of this type against us, even if the lawsuit is without merit, we could incur substantial costs defending the lawsuit. Any such lawsuit could also divert the time and attention of management.

Any failure to meet the continued listing requirements of NYSE American could result in a delisting of our Common Stock and our Warrants.

If we fail to satisfy the continued listing requirements of NYSE American, such as failing to satisfy any applicable corporate governance requirements or the minimum closing bid price requirement, NYSE American may take steps to delist our securities. Such a delisting would likely have a negative effect on the price of our securities and would impair your ability to sell or purchase the securities when you wish to do so. In the event of a delisting, we can provide no assurance that any action taken by us to restore compliance with listing requirements would allow our securities to become listed again, stabilize the market price or improve the liquidity of our securities, prevent our securities from dropping below the NYSE American minimum bid price requirement or prevent future non-compliance with NYSE American’s listing requirements. Additionally, if our securities are not listed on, or become delisted from, NYSE American for any reason, and are quoted on the OTC Bulletin Board, an inter-dealer automated quotation system for equity securities that is not a national securities exchange, the liquidity and price of our securities may be more limited than if our securities were quoted or listed on NYSE American or another national securities exchange. You may be unable to sell your securities unless a market can be established or sustained.

We are an “emerging growth company” and it cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our Common Stock less attractive to investors, which may make it more difficult to compare our performance with other public companies.

We are an emerging growth company as defined in the JOBS Act, and we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies for up to five years following the completion of this offering, including not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. To the extent we continue to take advantage of any of these exemptions, the information that we provide stockholders may be different than what is available with respect to other public companies. Investors may find the our Common Stock less attractive because we will continue to rely on these exemptions. If some

46

Table of Contents

investors find the our Common Stock less attractive as a result, there may be a less active trading market for the Common Stock, and the stock price may be more volatile.

An emerging growth company may elect to delay the adoption of new or revised accounting standards. Because we have made this election, Section 102(b)(2) of the JOBS Act allows us to delay adoption of new or revised accounting standards until those standards apply to non-public business entities. As a result, the financial statements contained in this prospectus and those that we will file in the future may not be comparable to companies that comply with public business entities revised accounting standards effective dates.

We are also a “smaller reporting company” as such term is defined in the Rule 12b-2 of the Exchange Act, meaning that the market value of our common stock held by non-affiliates plus the proposed aggregate amount of gross proceeds to us as a result of this offering is less than $700 million and our annual revenue is less than $100 million during the most recently completed fiscal year. Even after we no longer qualify as an emerging growth company, we may still qualify as a “smaller reporting company” which would allow us to take advantage of many of the same exemptions from disclosure requirements, including exemption from compliance with the auditor attestation requirements of Section 404 and reduced disclosure obligations regarding executive compensation in periodic reports and proxy statements. Investors could find our Common Stock less attractive because it may rely on these exemptions. If some investors find our Common Stock less attractive as a result, there may be a less active trading market for our Common Stock and the trading price may be more volatile.

Future sales and issuances of our Common Stock or rights to purchase our Common Stock could result in additional dilution of the percentage ownership of our stockholders and could cause our Common Stock price to fall.

The net proceeds from the Business Combination, along with our cash, are sufficient to fund our operating plans through at least June 30, 2024. However, we have based these estimates on numerous assumptions that may prove to be wrong, and we could spend our available capital resources much faster than we currently expect or require more capital to fund our operations than we currently expect. Significant additional capital will be needed in the future to continue our planned operations, including further development of our product candidate ABP-450, preparing INDs or equivalent filings, conducting preclinical studies and clinical trials, commercialization efforts, expanded R&D activities and costs associated with operating a public company. To raise capital, we may sell Common Stock, convertible securities or other equity securities in one or more transactions at prices and in a manner as determined from time to time. If we sell Common Stock, convertible securities or other equity securities, existing investors may be materially diluted by subsequent sales. New investors could gain rights, preferences and privileges senior to the holders of our Common Stock.

Pursuant to the 2023 Incentive Award Plan, or “the 2023 Plan”, our Board or Compensation Committee is authorized to grant equity-based awards to our employees, directors and consultants. Initially, the aggregate number of shares of our Common Stock that may be issued pursuant to stock awards under the 2023 Plan is 3,839,892 shares. Additionally, the number of shares of our Common Stock reserved for issuance under the 2023 Plan will automatically increase on January 1 of each year, beginning in 2024 and ending in 2033, by an amount equal to the lesser of (i) 4% of the number of fully-diluted number of shares outstanding (as calculated pursuant to the terms of the 2023 Plan) on the final day of the immediately preceding calendar year or (ii) such lesser number of shares as is determined by our Board.

Pursuant to the Employee Stock Purchase Program, or ESPP, our employees will have the opportunity to purchase shares of our Common Stock at a discount through accumulated payroll deductions. Initially, the aggregate number of shares of Common Stock that may be issued under the ESPP is 488,146 shares. In addition, the number of shares of Common Stock available for issuance under the ESPP will be annually increased on January 1 of each calendar year beginning in 2024 and ending in 2033 by an amount equal to the lesser of (a) 1% of the fully-diluted number of shares outstanding (as calculated pursuant to the terms of the ESPP) on the final day of the immediately preceding calendar year or (b) such lesser number of shares as is determined by our Board. Unless our Board elects not to increase the number of shares available for future grant each year, our stockholders may experience additional dilution, which could cause the price of our Common Stock to fall.

Our issuance of additional shares of Common Stock or other equity securities of equal or senior rank would, all else being equal, have the following effects:

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

We must design its disclosure controls and procedures to reasonably assure that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. For example, our directors or executive officers could inadvertently fail to disclose a new relationship or arrangement causing us to fail to make a required related party transaction disclosure. Additionally, controls and procedures can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of the inherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

Reports published by analysts, including projections in those reports that differ from our actual results, could adversely affect the price and trading volume of our Common Stock.

We currently expect that securities research analysts will establish and publish their own periodic financial projections for the business of AEON. These projections may vary widely and may not accurately predict the results AEON actually achieves. AEON’s stock price may decline if its actual results do not match the projections of these securities research analysts. Similarly, if one or more of the analysts who write reports on AEON downgrades its stock or publishes inaccurate or unfavorable research about its business, AEON’s stock price could decline. If one or more of these analysts ceases coverage of AEON or fails to publish reports on AEON regularly, its stock price or trading volume could decline. While we expect research analyst coverage, if no analysts commence coverage of AEON, the trading price and volume for AEON common stock could be adversely affected.

The obligations associated with being a public company involve significant expenses and require significant Resources and management attention, which may divert from AEON’s business operations.

As a public company, AEON is subject to the reporting requirements of the Exchange Act and the Sarbanes-Oxley Act. The Exchange Act requires the filing of annual, quarterly and current reports with respect to a public company’s business and financial condition. The Sarbanes-Oxley Act requires, among other things, that a public company establish and maintain effective internal control over financial reporting. The listing requirements of NYSE American also require that we satisfy certain corporate governance requirements. As a result, AEON will incur significant legal, accounting and other expenses that AEON did not previously incur. AEON’s entire management team and many of its other employees will need to devote substantial time to compliance, and may not effectively or efficiently manage its transition into a public company.

These rules and regulations will result in AEON incurring substantial legal, financial and accounting compliance costs in addition to other expenses and will make some activities more time-consuming and costly. The increased costs will decrease our net income or increase our consolidated net loss, and may require us to reduce costs in other areas of our business or increase the prices of our products or services. For example, these rules and regulations will likely make it more difficult and more expensive for AEON to obtain director and officer liability insurance, and it may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. As a result, it may be difficult for AEON to attract and retain qualified people to serve on its Board, its Board committees or as executive officers.

Provisions in AEON’s certificate of incorporation, AEON’s bylaws and Delaware law have anti-takeover effects that discourage an acquisition of AEON by others, even if an acquisition would be beneficial to our stockholders, and may prevent attempts by our stockholders to replace or remove our current management, which could depress the trading price of our Common Stock.

AEON’s certificate of incorporation, bylaws, and Delaware law contain provisions that may have the effect of discouraging, delaying or preventing a change in control of us or changes in our management that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares. AEON’s certificate of incorporation and bylaws include provisions that:

In addition, because we are incorporated in the State of Delaware, we are governed by the provisions of Section 203 of the DGCL, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

Any provision of our certificate of incorporation, bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our Common Stock, and could also affect the price that some investors are willing to pay for our Common Stock.

AEON’s certificate of incorporation and bylaws designate the Court of Chancery of the State of Delaware as the exclusive forum for certain state law litigation that may be initiated by our stockholders and the United States federal district courts as the exclusive forum for certain securities law actions, which could limit our stockholders’ ability to litigate disputes with us in a different judicial forum and increase the costs for our stockholders to pursue certain claims against us.

Pursuant to AEON’s bylaws and certificate of incorporation, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers or employees to us or our stockholders; (iii) any action asserting a claim arising pursuant to any provision of the DGCL, AEON’s certificate of incorporation and bylaws (including their interpretation, validity or enforceability); or (iv) any action asserting a claim governed by the internal affairs doctrine. This exclusive forum provision will not apply to any causes of action arising under the Securities Act or the Exchange Act or any

49

Table of Contents

other claim for which the federal courts have exclusive jurisdiction. Stockholders cannot waive compliance with the Securities Act, the Exchange Act or any other federal securities laws or the rules and regulations thereunder.

Unless we consent in writing to the selection of an alternate forum, the United States federal district courts shall be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. In addition, our bylaws provide that any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have notice of and consented to these exclusive forum provisions. The forum selection provisions in our bylaws may limit our stockholders’ ability to litigate disputes with us in a judicial forum that they find favorable for disputes with us or our directors, officers or employees, which may discourage the filing of lawsuits against us and our directors, officers and employees, even though an action, if successful, might benefit our stockholders. In addition, these forum selection provisions may impose additional litigation costs for stockholders who determine to pursue any such lawsuits against us.
