AEON Biopharma Inc

Our primary sources of capital have been debt financing (Predecessor) and equity financing (Successor). We have experienced recurring losses from operations and have a net capital deficiency and negative cash flows from operations since our inception. As of September 30, 2024 (Successor), we had reported cash and cash equivalents of $0.5 million and an accumulated deficit of $433.7 million.

On May 3, 2024, we announced preliminary top-line results from its planned interim analysis of the Phase 2 trial with ABP-450 in the preventative treatment of chronic migraine, which did not meet the primary or secondary endpoints. We originally intended to pursue submission of an Original BLA seeking one or more potential therapeutic indications for ABP-450. However, in May 2024, we announced the discontinuation of our Phase 2 clinical trials for episodic and chronic migraine in order to implement certain cash preservation measures. On July 9, 2024, we announced a strategic reprioritization to pursue a 351(k) biosimilar regulatory pathway for ABP-450, using AbbVie Inc.’s product Botox as a proposed reference product for all of the indications for which Botox is approved, other than the cosmetic uses. We are continuing to evaluate other cash preservation measures and will review all strategic options.

Prior to the Merger, Priveterra had entered into separate Forward Purchase Agreements with each of ACM and Polar. The Forward Purchase Agreements provided that each of Polar and ACM would separately be paid directly the Prepayment Amount, which was equal to an aggregate of $66.7 million based on the product of (i) 6,275,000 Additional Shares and (ii) the redemption price per share of $10.63. In satisfaction of the Prepayment Amount, on July 21, 2023, $66.7 million was obligated to be paid from the purchase of the Additional Shares by each of ACM and Polar pursuant to the terms of certain FPA Funding Amount PIPE Subscription Agreements between Priveterra and each of ACM and Polar.

On March 18, 2024, we entered into separate FPA Termination Agreements with each of ACM and Polar terminating their respective Forward Purchase Agreements. The FPA Termination Agreement with ACM provides that (i) ACM will retain 3,100,000 previously issued Additional Shares held by ACM pursuant to its respective Forward Purchase Agreement and subscription agreement and (ii) we will be subject to up to $1.5 million in liquidated damages, subject to certain conditions set forth in ACM’s respective FPA Termination Agreement. The Termination Agreement with Polar provides that (i) Polar will retain 3,175,000 previously issued Additional Shares held by Polar pursuant to its respective Forward Purchase Agreement and subscription agreement and (ii) we will be subject to up to $1.5 million in liquidated damages, subject to certain conditions set forth in Polar’s respective FPA Termination Agreement. We did not have access to the Prepayment Amount at any time following the Closing and, pursuant to the FPA Termination Agreements, ACM and Polar will retain the Prepayment Amount in full. The potential aggregate liquidated damages of up to $3.0 million was accrued as a liability in the first quarter of 2024. However, since each FPA provider elected to remove its respective shares from the registration statement, the Company released the liability in the second quarter of 2024. The terminated access to the Prepayment Amount may adversely affect our liquidity and capital needs.

On March 19, 2024, we entered into the Subscription Agreement with Daewoong relating to our sale and issuance of Convertible Notes in the principal amount of up to $15.0 million, which are convertible into shares of common stock, subject to certain conditions and limitations set forth in each Convertible Note. Each Convertible Note will contain customary events of default, will accrue interest at an annual rate of 15.79% and will have a maturity date that is three years from the funding date, unless earlier repurchased, converted or redeemed in accordance with its terms prior to such date. We will use the net proceeds from each Convertible Note to support the late-stage clinical development of ABP-450 and for general working capital purposes. Pursuant to the terms of the Subscription Agreement, on March 24, 2024, we issued and sold to Daewoong one Convertible Note in the principal amount of $5.0 million. The Subscription Agreement further provides that we will issue and sell to Daewoong a second Convertible Note in the

principal amount of $10.0 million no later than thirty (30) days following our compliance with certain conditions set forth in the Subscription Agreement, including our execution of an amendment to the License Agreement with Daewoong.

On March 19, 2024, we entered into the License Agreement Amendment with Daewoong, which amends the License Agreement. Pursuant to the terms of the License Agreement Amendment, the License Agreement will terminate if, over any six-month period, (a) we cease to commercialize ABP-450 in certain territories specified in the License Agreement and (b) we cease to advance any clinical studies of ABP-450 in such territories. The License Agreement Amendment also provides that, in the event that the License Agreement is terminated for the foregoing reasons, Daewoong will have the right to purchase all Know- How (as defined in the License Agreement) related to ABP-450 for a price of $1.00. The Termination Purchase Right will terminate and expire upon Daewoong’s sale of 50% of its common stock, including common stock held by its affiliates and common stock that would be issued upon an Automatic Conversion or Optional Conversion (as defined in the Convertible Notes).

On July 9, 2024, we announced a strategic reprioritization to pursue a Section 351(k) biosimilar regulatory pathway for ABP-450, using AbbVie Inc.’s product Botox as a proposed reference product. We held an initial meeting with the FDA in the third quarter of 2024 during which we aligned with the FDA on next steps to develop a Botox biosimilar. We anticipate commencing comparative analytic studies in the fourth quarter of 2024 and preparing for a potential Biosimilar Biological Product Development (“BPD”) meeting with the FDA in 2025 to review the results from the studies. However, the commencement of studies, preparation for the potential BPD meeting and any further development of ABP-450 would require additional funding in the form of equity financings or debt. There can be no assurance that such efforts will be successful or that, in the event that they are successful, the terms and conditions of such financing will be commercially acceptable. Furthermore, the use of equity as a source of financing would dilute existing shareholders.

As of the date of this Report, we expect to have sufficient cash to fund our operating plan into the fourth quarter of 2024. We are actively attempting to secure additional capital to fund our operations. However, we cannot assure you that we will be able to raise additional capital on commercially reasonable terms or at all.

We have incurred operating losses and negative cash flows from operating activities since inception and expect to continue to incur significant operating losses for the foreseeable future and may never become profitable. Our primary use of cash is to fund operating expenses, which consist of R&D expenditures, including clinical trials, as well as SG&A expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay or prepay these expenses. We expect to continue to incur substantial costs in order to conduct R&D activities necessary to develop and commercialize our product candidates. Until such time, if ever, as we can generate substantial product revenue from sales of ABP-450, we will need additional capital to undertake these activities and commercialization efforts, and, therefore, we intend to raise such capital through the issuance of additional equity, borrowings, and potentially strategic alliances with other companies. However, if such financing is not available at adequate levels or on acceptable terms, we could be required to reduce the scope of or eliminate some of our development programs or commercialization efforts, out-license intellectual property rights to our product candidates or sell unsecured assets, or a combination of the above, any of which may have a material adverse effect on our business, results of operations, financial condition and/or our ability to fund our scheduled obligations on a timely basis or at all. Our ability to continue as a going concern is dependent upon our ability to successfully accomplish these plans and secure sources of financing and ultimately attain profitable operations.

We may also seek to raise additional capital through the sale of public or private equity or convertible debt securities. If we incur additional debt, the debt holders would have rights senior to holders of common stock to make claims on our assets, and the terms of any debt could restrict our operations, including our ability to pay dividends to holders of our common stock. If we undertake discretionary financing by issuing equity securities or convertible debt securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at a price per share that is less than the price per share paid by current public stockholders. If we sell common stock, convertible securities, or other equity securities in more than one transaction, stockholders may be further diluted by subsequent sales. Additionally, future equity financings may result in new investors receiving rights superior to our existing stockholders. Because our decision to issue securities in the future will depend on numerous considerations, including factors beyond our control, we cannot predict or estimate the amount, timing, or nature of any future issuances of debt or equity securities. As a result, our stockholders bear the risk of future issuances of debt or equity securities reducing the value of our common stock and diluting their interests.

We may receive additional capital from the cash exercise of the Private Placement Warrants. However, the exercise price of our Private Placement Warrants is $11.50 per warrant and the last reported sales price of our common stock on November 11, 2024 was

$0.82. The likelihood that holders of the Private Placement Warrants will exercise their Private Placement Warrants, and therefore the likelihood of any amount of cash proceeds that we may receive, is dependent upon the trading price of our common stock after effectiveness of the registration statement related thereto registering the issuance of common stock underlying the Private Placement Warrants. If the trading price for our common stock does not maintain a price above $11.50 per share, we do not expect holders to exercise their Warrants for cash. We will have broad discretion over the use of any proceeds from the exercise of such securities. Any proceeds from the exercise of such securities would increase our liquidity, but we are not currently budgeting for any cash proceeds from the exercise of the Private Placement Warrants when planning for our operational funding needs. The Private Placement Warrants may be exercised on a cashless basis at any time and we will not receive any proceeds from such exercise, even if the Private Placement Warrants are in-the-money.

To the extent that 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 valuable rights to our product candidates, future revenue streams, research programs or product licenses on terms that may not be favorable to us. If these sources are insufficient to satisfy our liquidity requirements, we will seek to raise additional funds through future equity or debt financings. If we raise additional funds by issuing equity securities, our stockholders would experience dilution. Additional debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. There can be no assurance that our efforts to procure additional financing will be successful or that, if they are successful, the terms and conditions of such financing will be favorable to us or our stockholders. If we are unable to raise additional financing when needed, we may be required to delay, reduce, or terminate the development, commercialization and marketing of our products and scale back our business and operations.

As a result of these conditions, management has concluded that substantial doubt about our ability to continue as a going concern exists as conditions and events, considered in the aggregate, indicate that it is probable that we will be unable to meet our obligations as they become due within one year after the date that the financial statements included in this Report are issued. Our financial information throughout this Report and our financial statements included elsewhere in this Report have been prepared on a basis that assumes that we will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. This financial information and our consolidated financial statements do not include any adjustments that may result from an unfavorable outcome of this uncertainty. Our ability to continue as a going concern is dependent upon our ability to successfully accomplish our business plans and secure sources of financing and ultimately attain profitable operations.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with United States generally accepted accounting principles (“GAAP”). The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and related disclosure of contingent assets and liabilities, revenue and expenses at the date of the financial statements as well as the expenses incurred during the reporting period. Generally, we base our estimates on historical experience and on various other assumptions in accordance with United States GAAP that we believe to be reasonable under the circumstances. Actual results may differ materially from these estimates under different assumptions or conditions and such differences could be material to the financial position and results of operations. On an ongoing basis, we evaluate our judgments and estimates in light of changes in circumstances, facts and experience. As of September 30, 2024, there have been no changes to our critical accounting policies from those reported on our Annual Report Form 10-K.

JOBS Act; Smaller Reporting Company

We are an emerging growth company, as defined in the Securities Act, as modified by the JOBS Act. For so long as we remain an emerging growth company, we are permitted and intend to rely on certain exemptions from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and any golden parachute payments not previously approved. In particular, in this Report, we have provided only two years of audited financial statements and unaudited financial statements and have not included all of the executive compensation- related information that would be required if we were not an emerging growth company. Section 102(b)(2) of the JOBS Act allows us to delay adoption of the new or revised accounting standards until those standards apply to non-public business entities. Accordingly, the information contained herein may be different than the information you receive from other public companies in which you hold stock.

We will remain an emerging growth company until the earliest of (i) the last day of the fiscal year following the fifth anniversary of Priveterra’s initial public offering (December 31, 2026), (ii) the last day of the fiscal year in which we have total annual gross revenue of at least $1.235 billion, (iii) the last day of the fiscal year in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Exchange Act, which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year, or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

We are also a “smaller reporting company,” as such term is defined in 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. We will continue to be a smaller reporting company if either (i) the market value of our common stock held by non-affiliates is less than $250 million or (ii) our annual revenue is less than $100 million during the most recently completed fiscal year and the market value of our common stock held by non-affiliates is less than $700 million. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies.

Specifically, as a smaller reporting company, we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation. Investors could find our common stock less attractive to the extent we 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.
