Item 1.01 Entry Into a Material Definitive Agreement.

Merger Agreement

As previously disclosed, on December 1, 2025, Apimeds Pharmaceuticals US, Inc, a Delaware corporation (the “Acquiror”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with (i) Apimeds Merger Sub, Inc., a Delaware corporation, (ii) MindWave Innovations Inc, a Delaware corporation (the “Company”), (iii) Lokahi Therapeutics, Inc., a Nevada corporation, and (iv) Erik Emerson, solely in his capacity as representative for the Bio Business. Unless otherwise defined herein, the capitalized terms used below are defined in the Merger Agreement.

The Acquiror subsequently determined that the Merger Agreement contained a scrivener’s error with respect to the inclusion of Sections 2.05(b) and 2.05(d), and the language in Section 3.01(b), which did not accurately reflect the agreement of the parties.

Sections 2.05(b) and 2.05(d) and any cross references to such sections were incorrectly included in the Merger Agreement, since the Company did not have the right to appoint directors in connection with the Merger Agreement. Sections 2.05(b) and 2.05(d) have been removed together with all cross references to such sections.

In Section 3.01(b) of the Merger Agreement, (i) the Common Stock Cap was incorrectly listed as 29.9% of the total number of shares of Acquiror Common Stock issued and outstanding as of the date of the Merger Agreement, and (ii) the Acquiror Preferred Stock issuable to the holders of Existing Company Common Stock was incorrectly listed as equal to 61% of the total issued and outstanding equity securities of the Acquiror (exclusive of the Acquiror Common Stock issued and calculated on a fully diluted basis). Section 3.01(b) of the Merger Agreement now states that (i) the Common Stock Cap is equal to 0% of the total number of shares of Acquiror Common Stock issued and outstanding as of the date of the Merger Agreement, and (ii) the Acquiror Preferred Stock issuable to holders of Existing Company Common Stock is equal to 90.9% of the total issued and outstanding equity securities of the Acquiror (calculated on a fully diluted basis).

The Acquiror is filing the corrected Merger Agreement as Exhibit 2.1 to this Amendment. No other material terms of the Merger Agreement are amended or modified.

Amendment to Securities Purchase Agreement

As previously disclosed, on December 1, 2025, the Acquiror entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with an institutional investor (the “Investor”), pursuant to which the Acquiror agreed to issue senior convertible notes in an aggregate principal amount of up to $120,900,000 at an 8% original issue discount over a 24-month period.

On December 8, 2025, the Acquiror and the Investor entered into Amendment No. 1 to the Securities Purchase Agreement (“Amendment No. 1”), under which the parties (i) clarified how long the Acquiror is prohibited from entering into a variable rate transaction, (ii) expanded the notification rights of the Investor if another funding event occurs, and (iii) extended the date for the Acquiror to complete the Initial Closing (as such term is defined in the Securities Purchase Agreement).

The foregoing summary of Amendment No. 1 does not purport to be complete and is qualified in its entirety by reference to the complete text of the agreement, which is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by this reference.

Item 3.03 Material Modification to Rights of Security Holders.

The information set forth in Item 5.03 of this Amendment is hereby incorporated by reference into this Item 3.03.

Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

The Company also determined that the Certificate of Designation filed with the Secretary of State of the State of Delaware on December 1, 2025, in connection with the Merger Agreement contained a scrivener’s error regarding the number of shares of Acquiror Preferred Stock designated as “Series A Convertible Preferred Stock.”

The Certificate of Designation previously stated that there were 7,263,865 shares of Acquiror Preferred Stock designated as “Series A Convertible Preferred Stock”. The correct number of shares of Acquiror Preferred Stock designated as “Series A Convertible Preferred Stock” is 7,477,017.

A corrected Certificate of Designation has been filed with the Secretary of State of the State of Delaware and is also being filed as Exhibit 3.1 to this Amendment.
