Item 3.03. Material Modification to Rights of Security Holders.

To the extent required by Item 3.03 of Form 8-K, the information regarding the Reverse Stock Split and Charter Amendment set forth in Item 5.03 of this Current Report on Form 8-K is incorporated by reference herein.

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

On July 23, 2026, Apimeds Pharmaceuticals US, Inc., a Delaware corporation (the “Company”), filed a Certificate of Amendment (the “Charter Amendment”) to the Company’s Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware to (i) effect a one-for-ten (1-for-10) reverse stock split (the “Reverse Stock Split”) of the Company’s issued and outstanding shares of common stock, and (ii) reduce the par value of the Company’s common stock from $0.01 per share to $0.001 per share. The Reverse Stock Split became effective as of 12:01 a.m. Eastern Time on July 24, 2026 (the “Effective Date”).

As previously disclosed, on December 1, 2025, the Company obtained approval of its stockholders holding a majority of the voting power of the Company’s outstanding capital stock, by written consent, to effect the Reverse Stock Split and the Charter Amendment. In connection with the stockholder approval, the Company filed and mailed an information statement to its stockholders pursuant to Rule 14c-2 under the Securities Exchange Act of 1934, as amended.

As a result of the Reverse Stock Split, at the Effective Date, every ten (10) shares of the Company’s issued and outstanding common stock were automatically combined into one (1) share of common stock, par value $0.001 per share. No fractional shares were issued in connection with the Reverse Stock Split. Stockholders who would otherwise have been entitled to receive a fractional share received one whole share of common stock in lieu thereof.

Immediately prior to the Reverse Stock Split, there were 15,091,180 shares of common stock issued and outstanding. Immediately following the Reverse Stock Split, there were 1,509,118 shares of common stock issued and outstanding. An additional 33,506 shares of common stock were subsequently issued to accommodate the rounding up of fractional shares at the beneficial holder level through the Depository Trust Company. The Reverse Stock Split did not change the number of authorized shares of common stock, which remains at 100,000,000 shares, or the number of authorized shares of preferred stock, which remains at 10,000,000 shares.

The Company’s common stock began trading on a split-adjusted basis on the NYSE American LLC under the symbol “APUS” at the open of trading on July 24, 2026. The new CUSIP number for the Company’s common stock following the Reverse Stock Split is 03771D201.

Proportionate adjustments were made to the number of shares of common stock underlying the Company’s outstanding equity awards and warrants, and to the exercise prices thereof.

The foregoing description of the Charter Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Charter Amendment, which is incorporated by reference as Exhibit 3.1 to this Current Report on Form 8-K.
