As previously disclosed in our Current Report on Form 8-K filed with the Securities and Exchange Commission on October 14, 2025, on October 7, 2025, Propanc Biopharma., Inc. (the “Company”) entered into a Securities Purchase Agreement (the “SPA”) with Hexstone Capital LLC (“Hexstone”) in connection with a private placement shares of Series C Preferred Stock (“Series C Preferred Stock”), subject to certain closing conditions. On November 4, 2025 the closing conditions under the SPA were completed and the company closed the transaction under the SPA, pursuant to which Hexstone purchased 100 shares of Series C Preferred Stock of the Company and a Warrant to purchase up to an additional 9,900 shares of Series C Preferred Stock, at an exercise price of $10,000 per Warrant share in exchange for cash payment of $1,000,099.00 to the Company. The shares of Series C Preferred Stock and the Warrant were issued pursuant to the private placement exemption from registration provided by Section 4(a)(2) of the Securities Act and/or by Rule 506 of Regulation D promulgated thereunder.

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

On November 4, 2025, the Company amended its Certificate of Incorporation and filed a Certificate of Designation with the Delaware Secretary of State that authorized the issuance of up to 9,900 shares of a new series of preferred stock, par value $0.01 per share, designated as “Series C Preferred Stock” for which the Board established the rights, preferences and limitations thereof. The Board authorized the Series C Preferred Stock pursuant to the authority given to the board of directors under the Certificate of Incorporation, which authorizes the issuance of up to ten million (10,000,000) shares of preferred stock, par value $0.01 per share, and authorizes the Board, by resolution, to establish any or all of the unissued shares of preferred stock, not then allocated to any series into one or more series and to fix and determine the designation of each such shares, the number of shares which shall constitute such series and certain preferences, limitations and relative rights of the shares of each series so established. The Certificate of Designation was filed as an amendment to the Company’s Certificate of Incorporation, as amended.

At any time after the initial issuance date, each share of Series C Preferred Stock shall be convertible into shares of common stock of the Company by the holder thereof by dividing the stated amount of each share of Series C Preferred Stock of $10,000 by the conversion price. The conversion price shall be the lesser of the fixed conversion price of $5.00 per share or 85% of the of the lowest trading price of the Common Stock during the period beginning on the day the holder sends a conversion notice to the Company and ending on the trading day on which the aggregate dollar volume of the Company’s common stock exceeds the product of the conversion amount set forth on the applicable conversion notice multiplied by seven (7) after the applicable holder receives the shares of common stock issuable upon conversion of the Series C Preferred Stock, subject to a five (5) trading day minimum.

The summary of the rights, privileges and preferences of the Series C Preferred Stock described above is qualified in its entirety by reference to the Certificate of Designation, a copy of which is attached as Exhibit 4.1 to this report and is incorporated herein by reference.
