– FDA Type 2a meeting scheduled for November 19, 2025, to review AEON’s analytical development plan and initial data – – Positive biosimilarity data for ABP-450 confirming identical amino-acid sequencing and highly similar functional characteristics submitted to FDA ahead of scheduled Type 2a meeting – – Two complementary financing transactions announced in November 2025 - $6 million PIPE financing and a proposed Daewoong note exchange - are expected to strengthen AEON’s balance sheet, reduce outstanding debt by more than 90%, accelerate the ABP-450 biosimilar program by up to six months, and extend cash runway into the second quarter of 2026 – IRVINE, Calif., Nov. 14, 2025 (GLOBE NEWSWIRE) -- AEON Biopharma, Inc. (“AEON” or the “Company”) (NYSE American: AEON), a biopharmaceutical company seeking an accelerated and full-label U.S. market entry by developing ABP-450 (prabotulinumtoxinA) as a BOTOX® (onabotulinumtoxinA) biosimilar, today announced its financial results for the quarter ended September 30, 2025, and provided a business update. “The foundation of AEON’s progress lies in our science and is underscored by years of market validation”, said Rob Bancroft, AEON’s President and Chief Executive Officer. “Our recently released analytical results confirm both ABP-450’s identical amino-acid sequencing of all visible portions and highly similar functional characteristics to BOTOX®. These results are supported by a globally approved and fully scaled manufacturing platform with approvals in 69 countries. Together, these scientific and global data points validate our biosimilar strategy and instill confidence in AEON’s path forward.” “On the strength of this foundation, we announced two complementary financing transactions with Daewoong Pharmaceutical and institutional investors that are expected to eliminate over 90% of our outstanding debt, strengthen our balance sheet, and extend our cash runway into the second quarter of 2026 while accelerating the ABP-450 program by up to six months. With our FDA Type 2a meeting scheduled later this month, we are entering the next phase of development from a position of scientific and financial strength.” Recent Clinical and Corporate Highlights Positive Biosimilarity Results In November 2025, AEON reported positive biosimilarity data for ABP-450, its proposed biosimilar to BOTOX®. Analytical results confirmed identical amino-acid sequencing and highly similar functional characteristics to BOTOX®. The analytical package has been submitted to the FDA ahead of AEON’s Type 2a meeting scheduled for November 19, 2025. LC-MS analysis demonstrated that the primary structure of ABP-450 exhibited a 100% amino-acid sequence match to BOTOX®, with sequence coverage of 93–99% across all five proteins comprising the 900 kDa botulinum toxin type A complex. Strategic Financing and Note Exchange Also in November 2025, AEON announced two complementary transactions - a $6 million PIPE financing and a proposed Daewoong Pharmaceutical note exchange - which, together, are expected to strengthen AEON’s balance sheet, reduce outstanding debt by more than 90% and extend cash runway into the second quarter of 2026 while accelerating the ABP-450 program by up to six months.

Liquidity and Capital Resources The Company reported cash and cash equivalents of $5.9 million as of September 30, 2025, which does not include expected proceeds from the November 2025 PIPE financing. Including the recent financing, the company’s cash and cash equivalents are expected to be sufficient to fund the Company’s operating plan through into the second quarter of 2026, well beyond its Type 2a meeting with the FDA scheduled for this month. Expected Upcoming Milestones November 19, 2025 – Expected results and path forward from Biosimilar Biological Product Development (BPD) Type 2a FDA meeting. About the U.S. Biosimilar Pathway The U.S. Food and Drug Administration (“FDA”) regulates biosimilars under the Public Health Service Act’s 351(k) pathway, which require 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. About AEON Biopharma AEON Biopharma is a biopharmaceutical company seeking accelerated and full-label access to the U.S. therapeutic neurotoxin market via biosimilarity to BOTOX. The U.S. therapeutic neurotoxin market exceeds $3.0 billion annually, representing a major opportunity for biosimilar entry. The Company’s lead asset is ABP-450 injection for debilitating medical conditions. ABP-450 is the same botulinum toxin complex currently approved and marketed for cosmetic indications by Evolus, Inc. under the name Jeuveau®. ABP-450 is manufactured by Daewoong Pharmaceutical in compliance with current Good Manufacturing Practice, or cGMP, in a facility that has been approved by the U.S. Food and Drug Administration, Health Canada, and European Medicines Agency. The product is approved as a biosimilar in India, Mexico, and the Philippines. 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.

With positive analytical data now submitted to the FDA and in anticipation of alignment with the FDA coming from our scheduled Type 2a meeting, AEON enters the next phase of its biosimilar development with strong alignment and a clear path toward value creation. The proceeds from today’s PIPE financing, excluding any potential warrant exercise, extends our cash runway into the second quarter of 2026, and through the receipt of the FDA Type 2a meeting minutes.” $6 Million PIPE Financing with Potential to Raise Over $7 Million in Additional Capital AEON entered into a securities purchase agreement for a private placement (“PIPE”) with two existing investors providing 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 total 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 notes, for a number of shares not to exceed 6,581,829 shares (the “anti-dilutive Warrants”).

The second closing of the PIPE will be subject to stockholder approval, the closing of the exchange of the Daewoong notes, and other customary closing conditions. The PIPE Warrants and anti-dilutive Warrants will be issued only at the second closing. Proceeds from the financing will enable uninterrupted execution of AEON’s analytical program and are expected to accelerate biosimilar development by up to six months. Daewoong Convertible Note Exchange AEON and Daewoong Pharmaceutical (“Daewoong”) have entered into a binding term sheet contemplating the exchange (the “Exchange”) of $15 million of existing convertible note principal plus accrued interest for an estimated 23,103,694 shares of AEON common stock (or pre-funded warrants in lieu of shares), a $1.5 million new convertible note due 2030, and 8 million cash-exercise warrants on the same terms as the PIPE Warrants, representing over $8 million in potential additional cash proceeds to AEON. The parties expect to enter into definitive documentation for the Exchange in the coming weeks. The consummation of the Exchange will be subject to stockholder approval. The Exchange will result in the elimination of more than 90% of AEON’s outstanding debt, strengthening of Daewoong’s long-term strategic alignment with the Company and transformation of AEON’s capital structure.
