IRVINE, Calif., Dec. 15, 2025 (GLOBE NEWSWIRE) -- AEON Biopharma, Inc. (“AEON” or the “Company”) (NYSE American: AEON), a biopharmaceutical company seeking accelerated and full-label U.S. market entry by developing ABP-450 (prabotulinumtoxinA) as a BOTOX (onabotulinumtoxinA) biosimilar, today announced that the Company and Daewoong Pharmaceutical (“Daewoong”) have entered into a definitive agreement to exchange the Company’s $15 million of convertible notes plus accrued interest into new equity, $1.5 million of new notes due 2030, and a cash-exercise warrant for 8 million shares of common stock, on the same terms as the warrants in the private placement financing announced in November 2025 (the “Exchange”). The cash-exercise warrants, if exercised, represent over $8 million in potential additional cash proceeds to AEON.

“We are pleased to report the signing of definitive documentation for our exchange of Daewoong’s existing AEON-issued debt,” said Rob Bancroft, President & Chief Executive Officer of AEON. “While the transaction remains subject to a shareholder vote, this is an impotant step forward in deleveraging the company and we believe sets the stage for continued progress for our ABP-450 biosimiliar strategy in 2026.”

Previously, AEON and Daewoong entered into a binding term sheet contemplating the Exchange. The parties have now completed the definitive documentation for the Exchange, which documentation aligns with the terms agreed upon in the binding term sheet. The consummation of the Exchange remains subject to stockholder approval.

The Exchange will result in the elimination of more than 90% of AEON’s outstanding debt, strengthen Daewoong’s long-term strategic alignment with the Company and the Company’s stockholders, and transform AEON’s capital structure.

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.
