Explanatory Note

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

As previously disclosed in the Original Report, on March 20, 2026, Inscobee Inc. (“Inscobee”) and Apimeds, Inc. (“Apimeds Korea”), provided the Company with an action by written consent of the majority stockholders of the Company (the “Stockholder Consent”), which, among other things, purported to remove Elona Kogan, Jakap Koo, Carol O’Donnell, and Dr. Bennett Weintraub as members of the Company’s board of directors (the “Board Removals”), and also purported to remove Dr. Vin Menon and Erick Frim as Chief Executive Officer and Chief Financial Officer of the Company, respectively (the “Officer Removals”).

The Stockholder Consent, including the Board Removals, the Officer Removals, and the purported appointment of replacement directors, is null and void, having been taken in direct violation of binding contractual obligations under the Support Agreement (as defined below) and applicable Delaware law.

As previously announced, the Company entered into that certain Agreement and Plan of Merger, signed and closed on December 1, 2025 (the “Merger Agreement”), with Apimeds Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of the Company, MindWave Innovations Inc., a Delaware corporation (“MindWave”), and other parties signatory thereto. Pursuant to the Merger Agreement, MindWave became a wholly owned subsidiary of the Company by virtue of a merger (the “Merger”). In connection with the Merger, Inscobee and Apimeds Korea each entered into a Stockholder Support and Lock-Up Agreement (the “Support Agreement”) with the Company and MindWave.

The Stockholder Consent violated at least three independent provisions of the Support Agreement:

Irrevocable Proxy (Section 4(a)(4)). Under the Support Agreement, Inscobee and Apimeds Korea each unconditionally and irrevocably granted to the Company a proxy and power of attorney to vote their shares of common stock in a manner consistent with the Support Agreement. The Support Agreement expressly provides that this irrevocable proxy is “coupled with an interest” and “may under no circumstances be revoked.” The Stockholder Consent used 6,416,365 shares of common stock that were subject to this irrevocable proxy. The Company, as proxy holder, did not authorize the use of these shares for the Stockholder Consent. Any vote or consent action taken using shares subject to an irrevocable proxy without the proxy holder’s authorization is void and without legal effect.

Waiver of Consent Rights (Section 7). Under the Support Agreement, Inscobee and Apimeds Korea each agreed to refrain from exercising any consent right that would impede, disrupt, or adversely affect the consummation of the Merger or any other transaction contemplated by the Merger Agreement. In addition, each expressly waived any and all individual approval or consent rights it may have under the Company’s organizational documents or the Delaware General Corporation Law with respect to the Merger Agreement, the Merger, or any other transaction contemplated thereby. The Stockholder Consent, which purported to remove the directors and officers responsible for implementing the transactions contemplated by the Merger Agreement, was taken in direct violation of this waiver.

Anti-Frustration Covenant (Section 4(a)(2)). Under the Support Agreement, Inscobee and Apimeds Korea each agreed to vote their shares against any action that would in any material respect impede, interfere with, delay, or frustrate the purposes of the Merger Agreement or any ancillary document thereto. The Stockholder Consent directly contravenes this covenant.

Section 4(b) of the Support Agreement expressly provides that any action attempted to be taken in violation of the foregoing provisions “will be null and void.” The Stockholder Consent is therefore void ab initio by the express terms of the contract to which Inscobee and Apimeds Korea are signatories.

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

As previously discussed in Item 5.02 of this Amendment, the Company has determined that the Stockholder Consent is invalid and of no force or effect. Accordingly, the amendment to the Company’s Amended and Restated Bylaws purportedly effected pursuant to the Stockholder Consent is likewise invalid and of no force or effect.

Item 8.01. Other Events.

As a result of the Company’s determination that the actions purportedly taken by Inscobee and Apimeds Korea in the Stockholder Consent are invalid and of no force or effect, the Company intends to proceed with effecting the actions described in its Information Statement on Schedule 14C, originally filed with the SEC on February 27, 2026, and first mailed to the Company’s stockholders on March 5, 2026.
