— Termination of the Forward Purchase Agreements simplifies AEON’s capitalization structure — — AEON to expand its Board of Directors with appointment of candidate selected by its strategic partner following full funding of transaction — IRVINE, Calif., March 19, 2024 (GLOBE NEWSWIRE) — AEON Biopharma, Inc. (“AEON” or the “Company”) (NYSE AMEX: AEON, AEON WS), a clinical-stage biopharmaceutical company focused on developing a proprietary botulinum toxin complex for the treatment of multiple debilitating medical conditions, today announced it has entered definitive agreements relating to a private placement (the “Private Placement”) of $15 million (the “Investment Amount”) aggregate principal amount of senior secured convertible notes (the “Notes”) with Daewoong Pharmaceutical Co., LTD. Proceeds from the Private Placement will be paid in a first installment of $5 million and a second installment of $10 million, in each case subject to the closing conditions set forth in the agreements. The Company expects the first installment to close before the end of March 2024 and the second to close in April 2024. Proceeds from the Private Placement will be used to support the late-stage clinical development of ABP-450 and for general working capital purposes. Upon funding of the second installment of the Investment Amount, the Company will appoint one designee of Daewoong to the AEON Board of Directors, subject to a customary due diligence process by AEON. The Daewoong designee must be a member of Daewoong’s senior management team. The Company also announced today in a separate press release the successful outcome from a productive end-of-Phase 2 (EOP2) meeting with the U.S. Food and Drug Administration (FDA) following the Phase 2 data for ABP-450 in episodic migraine previously released in October 2023, which supports advancing ABP-450 (prabotulinumtoxinA) injection into the planned Phase 3 trials. In addition, the Company announced plans to conduct an interim analysis of the ongoing Phase 2 program for ABP-450 in chronic migraine in the second quarter. Concurrent with the execution of the agreements for the Private Placement, the Company terminated its forward purchase agreements (each an “FPA” and the counterparties thereto, together, the “FPA Providers”). Under the terms of the negotiated termination, the FPA Providers are entitled to keep the aggregate 6,275,000 shares of the common stock they currently hold as a result of the FPAs and will not be obligated to pay the Company any settlement amount or other fees otherwise due under the FPAs. The Company anticipates termination of the FPAs will help simplify and clarify the Company’s capitalization structure. Additional information about the Private Placement and the termination of the FPAs will be included in a Current Report on Form 8-K that the Company will file with the Securities Exchange Commission. This press release does not constitute an offer to sell or the solicitation of an offer to buy any security, nor shall there be any offer, solicitation or sale of any security, in any jurisdiction in which such offering, solicitation or sale would be unlawful. About ABP-450 (prabotulinumtoxinA) Injection ABP-450 contains a 900 kDa botulinum toxin type-A complex produced by the bacterium Clostridium botulinum. The active part of the botulinum toxin is the 150 kDa component, and the remaining 750 kDa of the complex is made up of accessory proteins that the Company believes help with the function of the active portion of the botulinum toxin. When injected at therapeutic levels, ABP-450 blocks peripheral acetylcholine release at presynaptic cholinergic nerve terminals by cleaving SNAP-25, a protein integral to the successful docking and release of acetylcholine from vesicles situated within the nerve endings leading to denervation and relaxation of the muscle.
