Registered Public Offering

On June 26, 2025, Reviva Pharmaceuticals Holdings, Inc. (the “Company”) entered into agreements, including a securities purchase agreement (the “Purchase Agreement”) with certain institutional investors, pursuant to which the Company agreed to sell and issue, in a registered public offering (the “Offering”), (i) an aggregate of 20,000,000 shares (the “Shares”) of the Company’s common stock, par value $0.0001 per share (“Common Stock”), (ii) Series C warrants (the “Series C Warrants”) exercisable for an aggregate of up to 20,000,000 shares of Common Stock (the “Series C Warrant Shares”) and (iii) Series D warrants (the “Series D Warrants” and together with the Series C Warrants, the “Warrants”) exercisable for an aggregate of up to 20,000,000 shares of Common Stock (the “Series D Warrant Shares” and together with the Series C Warrant Shares, the “Warrant Shares”), for aggregate gross proceeds of $10.0 million. Each share of Common Stock is being sold together with (i) a Series C Warrant to purchase one share of Common Stock and (ii) a Series D Warrant to purchase one share of Common Stock, at a combined public offering price of $0.50 per share of Common Stock and accompanying Warrants. The Series C Warrants are exercisable immediately, have a term of five years and have an exercise price of $0.50 per share. The Series D Warrants are exercisable immediately, have a term of 12 months and have an exercise price of $0.50 per share. The Warrants may only be exercised on a cashless basis if there is no registration statement registering, or the prospectus contained therein in not available for, the issuance of shares of Common Stock underlying the respective Warrants to the holder. The Company is prohibited from effecting an exercise of any Warrants to the extent that such exercise would result in the number of shares of Common Stock beneficially owned by such holder and its affiliates exceeding 4.99% (or 9.99% at election of the holder) of the total number of shares of Common Stock outstanding immediately after giving effect to the exercise, which percentage may be increased or decreased at the holder’s election not to exceed 9.99%. In the event of certain fundamental transactions, holders of the Warrants will have the right to receive the Black Scholes Value of their Warrants calculated pursuant to a formula set forth in the Warrants, payable either in cash or in the same type or form of consideration that is being offered and being paid to the holders of Common Stock in such fundamental transaction.

The net proceeds to the Company from the Offering are expected to be approximately $9.0 million, after deducting placement agent fees and expenses and other estimated offering expenses payable by the Company. The Company currently intends to use the net proceeds from the Offering, together with its existing cash and cash equivalents, to fund research and development activities and for working capital and other general corporate purposes.

The Offering is expected to close on or about June 27, 2025, subject to the satisfaction of customary closing conditions.

The Shares, Series C Warrants, Series D Warrants, Series C Warrant Shares and Series D Warrant Shares are being offered pursuant to the Company’s effective registration statement on Form S-3 (File No. 333-276848) filed on February 2, 2024 and declared effective on February 13, 2024 by the Securities and Exchange Commission (the “SEC”) and a prospectus supplement and accompanying prospectus filed with the SEC.

The Purchase Agreement contains customary representations, warranties and agreements by the Company, conditions to closing, indemnification obligations of the Company and the investors party thereto, other obligations of the parties and termination provisions. Pursuant to the terms of the Purchase Agreement, the Company has agreed to certain restrictions on the issuance and sale of its Common Stock and securities convertible into shares of Common Stock during the 60-day period following the closing of the Offering. In addition, the Company has agreed not to effect or enter into an agreement to effect any issuance of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock involving a Variable Rate Transaction (as defined in the Purchase Agreement) until one year following the closing of the Offering; provided that after 60 days following the closing of the Offering, the issuance of shares of Common Stock pursuant to the At Market Issuance Sales Agreement entered into by the Company and the Placement Agent (as defined below) and B. Riley Securities, Inc. on May 30, 2025 shall not be deemed a Variable Rate Transaction. The representations, warranties and covenants contained in the Purchase Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties.

Placement Agency Agreement

In connection with the Offering, the Company entered into a placement agency agreement (the “Placement Agency Agreement”), dated June 26, 2025, with A.G.P./Alliance Global Partners (the “Placement Agent”) pursuant to which the Company agreed to pay the Placement Agent a total cash fee equal to 7.0% of the aggregate gross proceeds of the Offering (with the exception of a 3.5% cash fee for gross proceeds raised from certain investors as mutually agreed upon by the Placement Agent and the Company) and to reimburse the Placement Agent for (i) up to $15,000 for non-accountable expenses and (ii) up to $75,000 for the out-of-pocket accountable legal expenses incurred by the Placement Agent in connection with the Offering.
