Some of the information contained in this discussion and analysis contains forward-looking statements that involve risks and uncertainties. As a result of many factors, such as those set forth in the sections of this Report captioned "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements", actual results may differ materially from those anticipated in these forward-looking statements. Unless the context otherwise requires, references to "we", "us", "our," "AEON" and "the Company" refer to the business and operations of AEON Biopharma, Inc. and its consolidated subsidiaries.

Company Overview

We are a biopharmaceutical company seeking accelerated and full-label United States ("U.S.") market entry by developing our ABP-450 as a BOTOXÒbiosimilar for debilitating medical conditions. We plan to develop and seek regulatory approval of ABP-450 as a biosimilar product in the U.S. through submission of a Biologics License Application,("BLA"), under Section 351(k) of the Public Health Service Act, ("Section 351(k) BLA") with the ultimate goal of addressing the global therapeutic botulinum toxin market, which we estimate to be at least $3.3 billion based on AbbVie's reported global revenues for its therapeutic Botox segment for the fiscal year ended 2024.ABP-450 is manufactured by Daewoong Pharmaceutical in compliance with current Good Manufacturing Practice ("cGMP"), in a facility that has been approved by the U.S. Food and Drug Administration, Health Canada, and European Medicines Agency. ABP-450 is the same botulinum toxin complex that is currently approved as a biosimilar in Mexico, India and Philippines and, in the U.S., is approved to provide temporary improvement in the appearance of moderate to severe glabellar lines for certain adult patients and marketed by Evolus, Inc. under the name Jeuveau in the U.S. and Nuceiva in Canada and the European Union. We have exclusive development and distribution rights fortherapeutic uses of ABP-450 in the U.S., Canada, the European Union, the United Kingdom, and certain other international territories. We have built a highly experienced management team with specific experience in biopharmaceutical and botulinum toxin development and commercialization.

We originally intended to pursue a submission of a BLA under Section 351(a) of the Public Health Service Act, or an Original BLA, seeking one or more potential therapeutic indications for ABP-450. We had completed a Phase 2 study of ABP-450 for the treatment of cervical dystonia and completed enrollment and dosing of patients for a Phase 2 double blind study of ABP-450 for the treatment of both chronic and episodic migraine. However, our Phase 2 clinical trials for episodic and chronic migraine did not meet their respective primary endpoints. 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 for which we do not hold development or commercialization rights.

The FDA regulates biosimilars under the Public Health Service Act's 351(k) pathway, which requires developers to demonstrate that a proposed product is highly similar to an approved reference biologic with no clinically meaningful differences in safety, purity, or potency. Analytical similarity is the scientific foundation of this process, representing the most critical and data-intensive phase of development. Once analytical comparability across key quality attributes is established, subsequent FDA interactions focus on confirming whether any residual uncertainty requires limited clinical evaluation.

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 commenced analytical studies in the fourth quarter of 2024 to prepare for an anticipated, now confirmed BPD Type 2a meeting with the FDA on November 19, 2025 to review the results from the analytical studies, including comparative primary structure analysis and select functional analyses.

The initial results from our analytical studies indicate a 100% amino acid sequence match confirmed between ABP-450 and Botox, based on sequence coverage of 93% to 99% for the five proteins that comprise the 900kD botulinum toxin type A complex, using liquid chromatography/mass spectrometry ("LC/MS") analysis of more than 3,400 peptides across multiple lots of ABP-450 and Botox, without any sequence deviations observed. Additionally, ABP-450 also demonstrated highly similar potency across two distinct assays (LD₅₀- in vivo biological activity and CBPA - cell-based potency assay) to support clinical dose predictability, comparable vial to vial active ingredient composition using ELISA - further supporting dose similarity and reliability, and functional

cleavage of SNAP-25, consistent with the mechanism of action. The Company expects to perform additional analyses to seek regulatory approval of ABP-450 as a biosimilar to Botox for therapeutic indications.

Botulinum toxins represent a well-characterized class of biologic therapeutics with over 230 potential therapeutic uses documented in the published scientific literature and twelve FDA-approved indications in the United States. ABP-450 has been previously evaluated in multiple clinical and preclinical programs, including Phase 2 studies in cervical dystonia and migraine and preclinical work in gastroparesis and neuropsychiatric models. The Phase 2 cervical dystonia program met its primary and key secondary endpoints and, together with its open-label safety extension, provides human clinical data supporting the safety and efficacy of ABP-450. We are not currently pursuing additional 351(a) indication-specific development programs, but we retain related intellectual property and know-how that could support future collaborations or lifecycle opportunities.

We license ABP-450 from Daewoong, a South Korean pharmaceutical manufacturer, and have exclusive development and distribution rights for therapeutic indications in the U.S., Canada, the European Union, the United Kingdom, and certain other international territories. Daewoong licenses the same 900 kDa botulinum toxin to Evolus for cosmetic indications, which Evolus markets and sells under the name Jeuveau in the United States and Nuceiva in Canada and the European Union. Prior to licensing the botulinum toxin complex to Evolus, Daewoong conducted a broad preclinical development program for ABP-450 that was primarily focused on safety to support any clinical indication. Subsequently, Evolus completed a comprehensive clinical development program of the same botulinum toxin complex and has received approval from regulatory authorities in the United States, the European Union and Canada to market and sell Jeuveau in the United States and Nuceiva in Canada and the European Union for the temporary improvement in the appearance of moderate to severe glabellar, or frown, lines in adults. Over 2,100 adult subjects with moderate to severe glabellar lines at maximum frown participated in Evolus' clinical development program, and each of Evolus' Phase 3 clinical studies successfully met their respective primary safety and efficacy endpoints. While none of these preclinical or clinical programs specifically contemplated any therapeutic use of ABP-450, given that the FDA's regulatory requirements are generally the same for the cosmetic or therapeutic use of a toxin, we believe that the positive data derived from these preclinical and clinical studies will support the clinical development and anticipated future safety labeling of ABP-450 for our 351(k) biosimilar program, across all labeled dose ranges.

We plan to pursue approval of a BLA under Section 351(k) that exclusively contemplates therapeutic indications for ABP-450, which we believe could improve provider reimbursement for ABP-450, if approved. Existing botulinum toxins, including Botox, are approved under a single BLA for both therapeutic and cosmetic indications. As a result, other botulinum toxins are required to include the sales prices of both therapeutic and cosmetic botulinum toxin sales when calculating the average selling price, or ASP, that is used to determine the reimbursement amount physicians receive for therapeutic usage. The inclusion of a lower cosmetic sales price in the calculation of ASP can cause physicians that inject for therapeutic applications 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. If we are successful in obtaining a BLA under Section 351(k) for therapeutic indications of ABP-450, the ASP for ABP-450 would be calculated using only therapeutic sales, which we believe would facilitate consistent and favorable product reimbursement to physicians when they choose to use ABP-450 for therapeutic treatments, as well as the ability to provide payors and/or providers with rebates and other financial incentives. This pricing model would be unique to us within the current therapeutic neurotoxin market, and we believe it would allow physicians to provide treatment with ABP-450 at a more competitive or the same net price as the market leader after rebates and discounts.

We have never been profitable from operations and, as of September 30, 2025, we had an accumulated deficit of $433.7 million. We have never generated revenue from ABP-450. We have concluded that we do not have sufficient cash to fund our operations for 12 months from the date of our financial statements without additional financing, and as a result, there is substantial doubt about our ability to continue as a going concern. As of the date of this Report, we expect to have sufficient cash to fund our operating plan into the second quarter of 2026, including funds anticipated to be received from the first and second closings of the PIPE Financing in November 2025. Any further development of ABP-450 for any indication, including the biosimilar pathway and any additional studies, will require additional funding, which may not be available to us on reasonable terms, or at all.

We do not expect to receive any revenue from ABP-450 or any future product candidates that we develop unless and until we obtain regulatory approval and commercialize ABP-450 or any future product candidates. We expect to continue to incur significant expenses and increasing net operating losses for the foreseeable future as we seek regulatory approval, prepare for and, if approved, proceed to commercialization of ABP-450.

Executive Overview

On April 19, 2025, the board of directors (the "Board") appointed Robert Bancroft as the Company's Principal Executive Officer, President, Chief Executive Officer and member of the Board, effective as of April 29, 2025, in connection with Marc Forth's resignation as the Company's President and Chief Executive Officer. Mr. Bancroft reports directly to the Board. Mr. Forth continues to serve as a member of the Board.

Liquidity and Capital Resources and Going Concern

As disclosed further below in the section titled "Liquidity and Capital Resources", 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. As of September 30, 2025, we had reported cash and cash equivalents of $5.9 million and an accumulated deficit of $433.7 million. 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 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.

Notice of Noncompliance

​

On February 3, 2025, the Company received a written notice of non-compliance (the "Notice") from NYSE American stating that the Company is not in compliance with continued listing standards of Section 1003(a)(i) of the NYSE American Company Guide (the "Company Guide"), which requires stockholders' equity of $2.0 million or more if the listed company has reported losses from continuing operations and/or net losses in two of its three most recent fiscal years (the "Minimum Requirement"), as defined in Section 1003(a)(i) of the Company Guide. Pursuant to the Notice, the Company reported a stockholders' deficit of $32.1 million at September 30, 2024 and has had losses in the two most recent fiscal years ended December 31, 2023 based on the Company's Annual Report on Form 10-K/A filed with the U.S. Securities and Exchange Commission on May 14, 2024, and the Company is not currently eligible for any exemption from the stockholders' equity requirement in Section 1003(a) of the Company Guide, and as such, NYSE American deems the Company below compliance with the Minimum Requirement. As required by the Notice, the Company submitted a plan to regain compliance with the continued listings standards of the Company Guide (the "Plan").

On April 22, 2025, the Company received a notification (the "Acceptance Letter") from NYSE American that the Plan was accepted. In the Acceptance Letter, NYSE American granted the Company until August 3, 2026 (the "Plan Period") to regain compliance with the continued listing standards. During the Plan Period, the Company will be subject to periodic review by NYSE American on its progress with the goals and initiatives outlined in the Plan. The Company intends to take all reasonable measures available to regain compliance with Sections 1003(a)(i), (ii) and (iii) of the Company Guide during the Plan Period. If the Company does not regain compliance with NYSE American listing standards by August 3, 2026, or if the Company does not make sufficient progress consistent with the Plan during the Plan Period, then NYSE American may initiate delisting proceedings.

The Acceptance Letter has no immediate impact on the listing of the Company's shares of Class A common stock, par value $0.0001 per share (the "Common Stock"), which will continue to be listed and traded on NYSE American during the Plan Period, subject to the Company's compliance with the other listing requirements of NYSE American. The Common Stock will continue to trade under the symbol "AEON". The Acceptance Letter does not affect the Company's ongoing business operations or its reporting requirements with the Securities and Exchange Commission. The Company intends to consider available options to resolve the non-compliance with the Minimum Requirement by August 3, 2026. However, there can be no assurance that the Company will be able to regain compliance with the Minimum Requirement.

Convertible Note Subscription

On March 19, 2024, we entered into the Subscription Agreement with Daewoong relating to our sale and issuance of the 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 contains customary events of default, accrues interest at an annual rate of 15.79% and has a maturity date that is three years from the funding date (the "Maturity 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 and, on April 12, 2024, we issued and sold to Daewoong an additional Convertible Note in the principal amount of $10.0 million.

On March 19, 2024, we entered into a Fourth Amendment to the License Agreement (the "License Agreement Amendment") with Daewoong, which amends that certain License and Supply Agreement, by and between us and Daewoong, dated December 20, 2019, as amended on July 29, 2022, January 8, 2023 and April 24, 2023 (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"). 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 below).

If, prior to the Maturity Date, the Company consummates a bona-fide third-party financing in the form of Common Stock or any securities convertible into, or exchangeable or exercisable for, Common Stock (subject to certain exceptions as described in each Convertible Note), in one or more transactions or a series of related and substantially similar and simultaneous transactions at the same purchase price from third parties unaffiliated with Daewoong and its affiliates, for aggregate gross cash proceeds to the Company of at least $30.0 million (a "Qualified Financing"), then, upon written notice thereof to Daewoong by the Company, on the closing date of such Qualified Financing, each Convertible Note will automatically convert in whole (the "Automatic Conversion") (subject to any limitations under the rules and regulations of NYSE American), without any further action by Daewoong, into a number of shares equal to: (i) one and three tenths (1.3) multiplied by (ii) the quotient of (a) the principal amount of each Convertible Note and all accrued and unpaid interest to be converted divided by (b) the per share price of the common stock sold in the Qualified Financing, provided that such per share price of common stock is at least $1.00 per share.

If, prior to the Maturity Date, the Company provides (i) written notice to Daewoong that it has publicly announced topline clinical data regarding its Phase 3 clinical study of ABP-450 for the treatment of chronic or episodic migraine, and such data indicates achievement of all primary endpoints or (ii) a written notice that the Company has consummated a Change of Control (as defined in each Convertible Note), Daewoong will have the right for thirty (30) days following receipt of either such notice, at Daewoong's option (the "Optional Conversion"), to convert all (but not less than all) of the remaining outstanding portion of each Convertible Note (subject to any limitations under the rules of NYSE American) into an amount of shares of common stock equal to: (i) one and three tenths (1.3) multiplied by (ii) the quotient of (a) the principal amount of each Convertible Note and all accrued and unpaid interest to be converted divided by (b) the volume weighted average trading per share price of common stock over the five (5) trading days prior to the Company's receipt of Daewoong's written notice of exercise of the Optional Conversion, provided that such per share price of common stock is at least $1.00 per share.

On November 13, 2025, the Company announced that it has entered into a binding term sheet with Daewoong contemplating the exchange of the 2024 Convertible Notes of $15.0 million in principal plus accrued interest for approximately 23,103,694 shares of Class A common stock (or pre-funded warrants in lieu of shares), a $1.5 million new convertible note due 2030 with interest rate of 15.79%, and approximately 8 million cash-exercise warrants on the same term as the PIPE Warrants (the "Exchange"). The parties expect to enter into definitive documentation for the Exchange in the coming weeks following execution of definitive documentation. The consummation of the Exchange will be subject to stockholder approval.

Public Offering

On January 6, 2025, we entered into an underwriting agreement with Aegis Capital Corp. ("Aegis" or the "Underwriter") pursuant to which the Company agreed to sell and issue, in an underwritten public offering (the "Offering") 555,571 Common Units, each consisting of (i) one (1) share of Common Stock, (ii) one (1) Series A Registered Common Warrant to purchase one (1) share of Common Stock per warrant at an exercise price of $45.00 (the "Series A Warrants") and (iii) one (1) Series B Registered Common Warrant to purchase one (1) share of Common Stock per warrant at an exercise price of $45.00 (the "Series B Warrants" and together with the Series A Warrants, the "Warrants"). Additionally, the Company granted Aegis a 45-day option to purchase additional shares of Common Stock and/or Warrants of (i) up to 15.0% of the number of shares of Common Stock sold in the offering, (ii) up to 15.0% of the number of Series A Warrants sold in the offering and (iii) up to 15.0% of the number of Series B Warrants sold in the offering. The purchase price per additional share of Common Stock is equal to the public offering price of one Common Unit (less $0.01 allocated to each full Warrant), less the underwriting discount. The purchase price per additional Warrant is $0.01. On January 7, 2025, Aegis exercised its over-allotment option with respect to 83,334 Series A Warrants and 83,334 Series B Warrants.

The closing of the Offering occurred on January 7, 2025. The Company received net proceeds of approximately $18.3 million from the Offering, after deducting the offering expenses payable by the Company, including the Underwriter's fees and expenses. The Company intends to use the net proceeds from the Offering for general corporate purposes, including working capital.

PIPE Financing

On November 12, 2025, the Company entered into a securities purchase agreement for a private placement ("PIPE") financing for: (i) the sale of 6,581,829 shares of the Company's Class A common stock (or pre-funded warrants in lieu of shares) at a price per share of $0.9116, for gross proceeds of $6 million; (ii) five-year warrants to purchase up to 6,581,829 shares of Class A common stock at an exercise price of $1.094 per share (the "PIPE Warrants"); and (iii) the investors' rights to receive anti-dilutive warrants following the exchange of the Daewoong 2024 Convertible Notes, for a number of shares not to exceed 6,581,829 shares (the "anti-dilutive Warrants"). The PIPE financing will close in two stages. The first closing is expected to occur in November 2025, subject to the satisfaction of customary closing conditions, and result in $1.79 million in gross proceeds to the Company. The second closing will be subject to stockholder approval, the closing of the exchange of the Daewoong 2024 Convertible Notes, and other customary closing conditions. The PIPE Warrants and anti-dilutive Warrants will be issued only at the second closing. The Company plans to use net proceeds to further advance analytical work for its ABP-450 biosimilar program, and for general corporate purposes.

Components of Our Results of Operations

Revenue

We have generated no revenue from the sale of products and do not anticipate deriving any product revenue unless and until we receive regulatory approval for, and are able to successfully commercialize, ABP-450.

Operating Expenses

Selling, General and Administrative Expenses

Selling, general and administrative ("SG&A") expenses, consist primarily of compensation for personnel, including stock-based compensation, management, finance, legal, and regulatory functions. Other SG&A expenses include travel expenses, market research and analysis, conferences and trade shows, professional services fees, including legal, audit and tax fees, insurance costs, general corporate expenses, and allocated facilities-related expenses. As we pivot to our biosimilar strategy, we anticipate that our SG&A expenses will decrease in the near-future to focus our resources to research and development ("R&D") activities. Additionally, we anticipate increased costs associated with being a public company, including expenses related to services associated with maintaining compliance with the requirements of NYSE American and the SEC, insurance, and investor relations costs. We expect to incur increased costs associated with establishing sales, marketing, and commercialization functions in advance of potential future regulatory approvals and commercialization of our product candidates. If ABP-450 obtains United States regulatory approval for any

indication, we expect that we would incur significantly increased expenses associated with building a sales and marketing team and funding commercial activities.

Research and Development Expenses

Our R&D expenses are primarily attributed to the development of ABP-450 as a biosimilar product in the United States through a Section 351(k) BLA, 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 for which we do not hold development or commercialization rights, which may include initiating a comparability study of ABP-450 in one or more of the indications currently approved for use by the proposed reference product.Due to the stage of our development and our ability to use resources across all of our programs, most of our R&D costs are not recorded on a program-specific basis. We expect our R&D expenses to increase as we, subject to raising additional capital, develop and seek regulatory approval of ABP-450. R&D expenses associated with these activities may include third-party costs such as expenses incurred under agreements with clinical research organizations, the cost of consultants who assist with the development of ABP-450 on a program-specific basis, investigator grants, sponsored research, product costs in connection with acquiring ABP-450 from Daewoong and Botox for use in conducting preclinical and clinical studies, and other third-party expenses attributable to the development of our product candidates.

R&D activities will be critical to achieving our business strategy. The biosimilar pathway will require significant costs in order to design, execute and complete the primary structural analysis and any additional analyses. Any clinical studies, such as a comparability study in any of the indications currently approved for use by the proposed reference product, will generally incur greater development costs than those programs incurred in the earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical studies. We expect our R&D expenses to be significant over the next years as we pursue the development of ABP-450 as a biosimilar and seek regulatory approval using Botox as the reference product. As a result, we are unable to determine the duration and completion costs of our programs or when and to what extent we will generate revenue from commercialization and sale of any of our product candidates. Our R&D activities may be subject to change from time to time as we evaluate our strategic plan, priorities and available resources.

Change in Fair Value of Contingent Consideration

The Company determined that the Contingent Consideration would be classified as a liability on the consolidated balance sheets and remeasured at each reporting period with changes to fair value recorded to the consolidated statements of operations and comprehensive (loss) income.

Other (Loss) Income, Net

Other (loss) income, net primarily consists of gains and losses resulting from the remeasurement of the fair value of our convertible notes, warrant liabilities, forward purchase agreements, and loss on issuance of warrants, each described below, at each balance sheet date.

Change in fair value of convertible notes - The Company elected the fair value option to account for its convertible notes, with the subsequent changes in fair value recorded in the consolidated statement of operations and comprehensive (loss) income.

Change in fair value of warrants - Changes in the estimated fair value of our warrant liabilities are recognized as a non-cash gain or loss on the consolidated statements of operations and comprehensive (loss) income.

Loss on embedded forward purchase agreement and make whole derivative - the Company has determined that each of its forward purchase agreements entered in connection with the Merger is a freestanding hybrid financial instrument comprising a subscription receivable and embedded features, which were bifurcated and accounted for separately as derivative instruments. The Company recorded the derivatives as liabilities and measured them at fair value. Subsequent changes in the bifurcated derivatives are recorded in the consolidated statements of operations and comprehensive (loss) income. Upon termination of the forward purchase agreements in the first quarter of fiscal 2024, the Company recorded a charge to the consolidated statement of operations of $20.3 million to reverse the related subscription receivable and derivative liability on the accompanying consolidated balance sheet.

Loss on issuance of warrants - the Company's issued Warrants in the first quarter of 2025 had grant date fair values of $94.0 million on January 7, 2025 and was recorded as a liability as of grant date. Proceeds were allocated to the warrant liability based on

the fair value as of grant date of the warrants of $94.0 million. As the fair value of the warrants issued were greater than the proceeds received, the Company recognized a loss on issuance of warrants of $75.6 million.

Results of Operations

The following table summarizes our results of operations for the periods indicated (in thousands):

Comparison of the three and nine months ended September 30, 2025 and 2024

Operating Expenses

Selling, General and Administrative (SG&A) Expenses

SG&A expenses were $1.9 million for the three months ended September 30, 2025, resulting in a decrease of $1.1 million, or 36%, compared to $3.0 million during the three months ended September 30, 2024. The decrease in SG&A expenses was primarily attributable to a decrease of $1.0 million related to reversal of share-based compensation expense related to restricted stock units ("RSU") with earnout criteria determined to be improbable in the third quarter of 2025, $0.4 million gain on the settlement with Odeon in the third quarter of 2025 and a $0.1 million decrease in business insurance costs due to lower renewal premiums, offset by $0.5 million of expense related to cash-settled restricted stock units ("RSU") that were issued in the second quarter of 2025.

SG&A expenses were $8.3 million for the nine months ended September 30, 2025, resulting in a decrease of $2.7 million, or 25%, compared to $11.0 million during the nine months ended September 30, 2024. The decrease in SG&A expenses was primarily attributable to a decrease of $1.0 million related to reversal of share-based compensation expense related to RSU with earnout criteria determined to be improbable in the third quarter of 2025, $1.2 million decrease in legal expenses and professional fees for the Company's registration statement filings in the prior year, $0.4 million gain on the settlement with Odeon in the third quarter of 2025, $0.4 million decrease in business insurance costs due to lower renewal premiums and a $0.3 million decrease in salaries due to headcount reduction in the prior year to preserve cash, offset by $0.7 million of expense related to cash-settled RSU that were issued in the second quarter of 2025.

Research and Development (R&D) Expenses

R&D expenses were $0.6 million for the three months ended September 30, 2025, a decrease of $0.4 million, or 40%, compared to $1.0 million for the three months ended September 30, 2024. The decrease was primarily attributable to $1.1 million decrease in R&D expenses due to wind down of Phase 2 clinical trials related to chronic and episodic migraine and cervical dystonia, including $0.6 million gain related to settlement of outstanding liabilities with the Company's clinical research organization related to its cervical dystonia and migraine programs, offset by an increase of $0.7 million for biosimilar consulting.

R&D expenses were $2.5 million for the nine months ended September 30, 2025, a decrease of $8.7 million, or 80%, compared to $11.1 million for the nine months ended September 30, 2024. The decrease was primarily attributable to a $9.4 million decrease in R&D expenses due to wind down of Phase 2 clinical trials related to chronic and episodic migraine and cervical dystonia, including $0.6 million related to settlement of outstanding liabilities with the Company's clinical research organization related to its cervical dystonia and migraine programs, and $0.3 million decrease in salaries due to headcount reduction in the prior year to preserve cash, offset by an increase of $1.1 million for biosimilar consulting.

Change in Fair Value of Contingent Consideration

The Company recognized gains of de minimus and $3.5 million for the three and nine months ended September 30, 2025, respectively, related to the change in the fair value of the contingent consideration related to certain contingent provisions, restrictions and forfeiture provisions for Founder Shares and certain Participating Stockholders shares. The gain was primarily due to a decrease in the Company's stock price from $38.88 to $0.81 as of December 31, 2024 and September 30, 2025, respectively. For the three and nine months ended September 30, 2024, the Company recognized gains of $0 and $97.5 million, respectively, primarily due to changes in the milestone probabilities in the second quarter of 2024 following the announcement of the Company's topline Phase 2 migraine results and fluctuations in the Company's stock price from $518.40 to $75.60 as of December 31, 2023 and September 30, 2024, respectively.

Loss on Issuance of Warrants

The Company's issued Warrants in the first quarter of 2025 had grant date fair values of $94.0 million on January 7, 2025 and was recorded as a liability as of grant date. Proceeds were allocated to the warrant liability based on the fair value as of grant date of the warrants of $94.0 million. As the fair value of the warrants issued were greater than the proceeds received, the Company recognized a loss on issuance of warrants of $75.6 million.

Other Income, Net

For the three and nine months ended September 30, 2025 and September 30, 2024, the Company recognized losses of $1.9 million, $5.4 million, $1.9 million, and $0.2 million related to change in fair value of convertible notes due to changes in stock price and conversion probabilities of the Daewoong convertible notes.

For the three months ended September 30, 2025 and 2024, the Company recognized losses of $0.2 million and $0.4 million, respectively, related to the change in fair value of warrants.

For the nine months ended September 30, 2025 and September 30, 2024, the Company recognized income of $86.0 million, offset by $75.6 million from fair value loss at issuance related to Series A and Series B warrants issued in the first quarter of fiscal 2025, compared to a loss of $15.4 million in the prior year, related to warrants issued at the Closing.

For the nine months ended September 30, 2024, the Company recognized a loss of $19.9 million related to the termination of the forward purchase agreements in 2024.

Liquidity and Capital Resources

Our primary sources of capital have been debt and equity financing. 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, 2025, we had reported cash and cash equivalents of $5.9 million and an accumulated deficit of $433.7 million.

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, the Company issued and sold to Daewoong one Convertible Note in the principal amount of $5.0 million, and on April 12, 2024, the Company issued and sold to Daewoong one Convertible Note in the principal amount of $10.0 million.

​

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 November 13, 2025, the Company announced that it has entered into a binding term sheet with Daewoong contemplating the exchange of the 2024 Convertible Notes of $15.0 million in principal plus accrued interest for approximately 23,103,694 shares of Class A common stock (or pre-funded warrants in lieu of shares), a $1.5 million new convertible note due 2030 with interest rate of 15.79%, and approximately 8 million cash-exercise warrants on the same term as the PIPE Warrants (the "Exchange"). The parties expect to enter into definitive documentation for the Exchange in the coming weeks following execution of definitive documentation. The consummation of the Exchange will be subject to stockholder approval.

​

On May 3, 2024, we announced preliminary top-line results from a 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 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 commenced analytical studies in the fourth quarter of 2024 to prepare for an anticipated, now confirmed BPD Type 2a meeting with the FDA on November 19, 2025 to review the results from the studies. However, the commencement of studies, preparation for an expected 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.

​

On January 6, 2025, we entered into an underwriting agreement with Aegis pursuant to which we agreed to sell and issue, in an underwritten public offering (the "Offering") 555,571 Common Units, each consisting of (i) one (1) share of Common Stock, (ii) one (1) Series A Registered Common Warrant to purchase one (1) share of Common Stock per warrant at an exercise price of $45.00 (the "Series A Warrants") and (iii) one (1) Series B Registered Common Warrant to purchase one (1) share of Common Stock per warrant at an exercise price of $45.00 (the "Series B Warrants" and together with the Series A Warrants, the "Warrants"). Additionally, the Company granted Aegis a 45-day option to purchase additional shares of Common Stock and/or Warrants of (i) up to 15.0% of the number of shares of Common Stock sold in the offering, (ii) up to 15.0% of the number of Series A Warrants sold in the offering and (iii) up to 15.0% of the number of Series B Warrants sold in the offering. The purchase price per additional share of Common Stock is equal to the public offering price of one Common Unit (less $0.01 allocated to each full Warrant), less the underwriting discount. The purchase price per additional Warrant is $0.01. On January 7, 2025, Aegis exercised its over-allotment option with respect to 83,334 Series A Warrants and 83,334 Series B Warrants. The Offering closed on January 7, 2025, and the Company received net proceeds of

approximately $18.3 million from the Offering, after deducting the offering expenses payable by the Company, including the Underwriter's fees and expenses.

​

On November 12, 2025, the Company entered into a securities purchase agreement for a private placement ("PIPE") financing for: (i) the sale of 6,581,829 shares of the Company's Class A common stock (or pre-funded warrants in lieu of shares) at a price per share of $0.9116, for gross proceeds of $6 million; (ii) five-year warrants to purchase up to 6,581,829 shares of Class A common stock at an exercise price of $1.094 per share (the "PIPE Warrants"); and (iii) the investors' rights to receive anti-dilutive warrants following the exchange of the Daewoong 2024 Convertible Notes, for a number of shares not to exceed 6,581,829 shares (the "anti-dilutive Warrants"). The PIPE financing will close in two stages. The first closing is expected to occur in November 2025, subject to the satisfaction of customary closing conditions, and result in $1.79 million in gross proceeds to the Company. The second closing will be subject to stockholder approval, the closing of the exchange of the Daewoong 2024 Convertible Notes, and other customary closing conditions. The PIPE Warrants and anti-dilutive Warrants will be issued only at the second closing. The Company plans to use net proceeds to further advance analytical work for its ABP-450 biosimilar program, and for general corporate purposes.

​

As of the date of this Report, we expect to have sufficient cash to fund our operating plan into the second quarter of 2026, including funds anticipated to be received from the first and second closings of the PIPE Financing in November 2025. We will actively attempt 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 $828.00 per warrant and the last reported sales price of our common stock on November 10, 2025 was $0.935. 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 $828.00 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.

Net Cash Used in Operating Activities

Net cash used in operating activities for the nine months ended September 30, 2025 was $12.6 million, consisting of a net loss of $2.1 million, non-cash gain of $4.7 million and changes in operating assets and liabilities of $5.8 million. Non-cash gain primarily consists of $86.0 million decrease related to change in fair value of warrants and $3.5 million decrease related to change in fair value of contingent consideration, offset by $75.6 million loss on issuance of warrants, $3.7 million related to stock-based compensation for our executives and directors and $5.4 million related to the change in fair value of the convertible notes. Decrease in cash used in operating activities of $7.1 million is primarily attributable to timing of clinical trial payments.

Net cash used in operating activities for the nine months ended September 30, 2024 was $19.7 million, consisting primarily of a net income of $39.9 million and non-cash charges of $(57.0) million, consisting primarily of $4.9 million non-cash expense related to stock-based compensation for our executives and directors, $0.2 million related to the change in fair value of the convertible notes, $15.4 million related to change in fair value of warrants, $19.9 million related to loss on forward purchase agreement and derivative liabilities, and $(97.5) million related to change in fair value of contingent consideration.

Cash Flows from Investing Activities

Net cash used in investing activities for the nine months ended September 30, 2025 and 2024 were a de minimus amount and zero, respectively, related to the purchase of property and equipment.

Cash Flows from Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2025 and 2024 were $18.5 million and $15.1 million, respectively, primarily related to the public offering in the first quarter of fiscal 2025 and proceeds from issuance of convertible notes in the first and second quarters of fiscal 2024, respectively.

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 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, 2025, 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 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 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.
