Management Comments

• "We lose around $20-$30 per vial on average. Sometimes, if we're lucky we can make $5 per vial, but often we don't. My coffee costs $6, how could I be happy with $5?" Neurologist, 200+ BOTOX patients/yr.
• "Every toxin has different units and dilution. We try not to maintain multiple workflows. It's a huge operational headache and creates room for error." Neurologist, 300+ BOTOX patients/yr.
• "BOTOX is the only one that truly covers everything. Dysport, XEOMIN, DAXXIFY they're all missing some of the major indications, so we use them less." Neurologist, 200+ BOTOX patients/yr.
• "For us, BOTOX represents well over 65% of the total neurotoxin dollars and they're all clinically appropriate, so there really isn't anything we can do to slow the use." Medical Director, National Plan with 10M+ lives covered.
• "Non-BOTOX products really haven't shown any superiority over BOTOX. Clinically they don't differentiate, and total-dollar-wise they're sometimes even higher than BOTOX, so there isn't a reason for us to try to push providers toward them." Medical Director, National Plan with 10M+ lives covered.
• "What limits Dysport, XEOMIN is their label. If a product has the full BOTOX indications, and it's identical and cheaper, I'd consider switching entirely." Neurologist, 300+ BOTOX patients/year.
• "If it's basically the same as BOTOX in how we use it, same workflow, same mixing, same injection, then switching wouldn't be an issue, it'd be a no-brainer." Neurologist, 300+ BOTOX patients/yr.
• "If neurologists want to use BOTOX, we can't steer them away. But if FDA deems the biosimilar as identical to BOTOX, we have something comparable that we can point them to." Medical Director, National Plan with 10M+ lives covered.
• "If a biosimilar is cheaper and does the same thing as BOTOX and providers can use it in the exact same way, we'd absolutely move volume towards it." Medical Director, National Plan with 10M+ lives covered.
• "If the ASP is at least 20% lower, I can move a lot of share to the biosimilar." Medical Director, Regional Plan with 3M+ lives covered.

Industry Context

The U.S. therapeutic neurotoxin market, valued at over $3.5 billion in 2025 and projected to exceed $5 billion by 2030, is heavily monopolized by BOTOX, which holds over 92% market share. Existing competitors like Dysport, Xeomin, Daxxify, and Myobloc have collectively captured less than 8% due to narrower labels, lack of clinical differentiation, and sometimes higher total costs. This situation leaves neurologists and payers frustrated by limited alternatives, rising costs, and operational complexities. AEON Biopharma aims to disrupt this by offering a true biosimilar with full label parity, addressing these unmet needs and introducing meaningful competition.

Comparison to Industry Standards

• BOTOX (AbbVie Inc.): Dominates the market with >92% share and 12 FDA-approved therapeutic indications, being the only product covering all major indications, including chronic migraine.
• Dysport (Ipsen Group), XEOMIN (Merz Pharma), DAXXIFY (Revance Therapeutics), Myobloc (Supernus Pharmaceuticals): Collectively hold <8% of the market. Their labels are significantly narrower than BOTOX, missing key indications, which limits their adoption by neurologists and creates operational friction.
• ABP-450 (AEON Biopharma): Aims to be clinically indistinguishable from BOTOX, targeting full label extrapolation for all 12 therapeutic indications. It is designed for operational simplicity (same vial size, dosing, dilution) to minimize switching friction, unlike current competitors which often require different workflows.
• Pricing: Current competitors often do not offer significant cost advantages or clinical superiority over BOTOX, leading to minimal payer leverage. ABP-450 intends to offer a lower-cost alternative with a therapeutic-only Average Sales Price (ASP) insulated from aesthetic price discounting, aiming to protect provider margins and enable payers to apply brand-specific policies.
• Manufacturing: ABP-450 leverages the Daewoong 900 kD toxin platform, which is globally validated and already approved in 69+ countries for aesthetics (Jeuveau by Evolus), providing a unique head start on quality, safety, and supply reliability compared to developing a new toxin from scratch.

Legal Proceedings

• The company faces risks related to the outcome of any legal proceedings that may be instituted against AEON or others.
• The ability to defend intellectual property or avoid infringement of existing intellectual property is a stated risk.

Related Party Transactions

• The conversion of Daewoong convertible notes, totaling approximately $19.3 million, into common stock, warrants, and a new note. Daewoong is a key partner and the source of the toxin platform for ABP-450.

Stakeholder Impact

• Shareholders: Potential for significant value creation through market disruption and accelerated biosimilar approval, supported by recent financing and debt conversion strengthening the balance sheet.
• Physicians (Neurologists): ABP-450 is designed to offer clinical sameness, operational simplicity, and protection of cost recovery, addressing current financial losses and workflow complexities associated with BOTOX.
• Payers: ABP-450 is expected to unlock new leverage for payers, enabling them to curb rising neurotoxin costs and achieve meaningful savings by offering a lower-cost, comparable alternative to BOTOX.
• Patients: Potential for lower out-of-pocket costs while maintaining equivalent treatment effectiveness due to the biosimilar nature of ABP-450.

Next Steps

• FDA BPD Type 2a Meeting on January 21, 2026, to clarify remaining analytical expectations and align on the forward plan.
• Stockholder approval for the Second Closing of the PIPE and the Daewoong note exchange, scheduled for January 21, 2026.
• Potential follow-up PK/PD work and targeted comparative clinical trials if requested by the FDA.
• Submission of a Biologics License Application (BLA) as a biosimilar for therapeutic uses of ABP-450.
• Continued development of ABP-450 towards full-label biosimilarity and market entry.
