– 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.
