Item 1.01. Entry into a Material Definitive Agreement.

On August 19, 2026, Apimeds Pharmaceuticals US, Inc., a Delaware corporation (the “Company”), entered into an Assignment and Transfer Agreement of Certain Apitox Rights (the “Assignment Agreement”) with FreeT Inc., a company organized under the laws of the Republic of Korea (“FreeT”). FreeT is the successor to CNP Roen Co., Ltd., which subsequently changed its corporate name to Inscobee Co., Ltd. and is currently known as FreeT Inc.

Pursuant to the Assignment Agreement, FreeT irrevocably assigned, transferred, conveyed and delivered to the Company all of FreeT’s right, title and interest in and to certain Apitox-related rights (the “Assigned Rights”) that were originally acquired by CNP Roen Co., Ltd. under an Apitox Rights Transfer Agreement dated June 16, 2015 (the “2015 Agreement”).

The Assigned Rights include: (i) one hundred percent (100%) of the rights relating to the Apitox market for Korean medicine clinics in the Republic of Korea; (ii) a twenty-five percent (25%) royalty entitlement on the economic proceeds arising from the development, licensing, sale or other commercialization of Apitox in the United States; (iii) a twenty-five percent (25%) revenue participation right on the net proceeds from overseas rights agreements; (iv) the right to receive quarterly information regarding the progress and status of the Apitox clinical program; (v) the right to receive quarterly information concerning the status and progress of overseas rights transactions involving Apitox; (vi) certain contractual benefits relating to data and technology for third-party manufacturing or rights agreements; and (vii) other ancillary contractual rights.

The Assigned Rights are limited to rights actually held by FreeT as of the effective date and only to the extent legally assignable. The Assignment Agreement expressly excludes any global rights not held by FreeT, any underlying intellectual property ownership in Apitox, and any indication-specific, territorial, manufacturing, regulatory or commercialization rights not granted to FreeT.

The Company has confirmed that the Assigned Rights are free and clear of any claims, encumbrances or obligations associated with any prior side letter arrangements, including those involving Lokahi Therapeutics Inc.

The Company assumed only those obligations, if any, that arise after the effective date and are directly related to the lawful exercise of the Assigned Rights. The Company does not assume any payment obligation, breach, liability, debt, claim or other obligation of FreeT arising before the effective date under the 2015 Agreement.

FreeT confirmed its intention to support the continued development, indication expansion and global commercialization of Apitox through the Company and to use commercially reasonable efforts to facilitate future transactions pursuant to which additional Apitox rights for territories worldwide outside the United States may be granted to the Company, subject to separate definitive agreements.

The Assignment Agreement is governed by the laws of the Republic of Korea, with exclusive jurisdiction in the Seoul Central District Court.

The foregoing summary of the Assignment Agreement does not purport to be a complete description and is qualified in its entirety by reference to the full text of the Assignment Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
