Item 1.01. Entry into a Material Definitive Agreement.

On April 3, 2020, Inovio Pharmaceuticals, Inc. (the “Company”) entered into an At-The-Market Equity Offering Sales Agreement (the “Sales Agreement”) with Stifel, Nicolaus & Company, Incorporated (“Stifel”) under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, par value $0.001 per share (the “Common Stock”), through Stifel as its sales agent. The Company has filed a prospectus supplement pursuant to the Sales Agreement for the offer and sale of its Common Stock having an aggregate offering price of up to $150,000,000.

Pursuant to the Sales Agreement, sales of the Common Stock, if any, will be made under the Company’s previously filed and effective Registration Statement on Form S-3 (File No. 333-237172) and an applicable prospectus supplement, by any method that is deemed to be an “at the market offering” as defined in Rule 415(a)(4) under the Securities Act of 1933, as amended. Subject to the terms and conditions of the Sales Agreement, Stifel may sell the Common Stock by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415(a)(4) of the Securities Act of 1933, as amended. Stifel will use commercially reasonable efforts to sell the Common Stock from time to time, based upon instructions from the Company (including any price, time or size limits or other customary parameters or conditions the Company may impose). The Company will pay Stifel a commission of up to three percent (3.0%) of the gross sales proceeds of any Common Stock sold through Stifel under the Sales Agreement, and also has provided Stifel with certain indemnification rights.

The foregoing description of the Sales Agreement is not complete and is qualified in its entirety by reference to the full text of the Sales Agreement, a copy of which is filed herewith as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy the securities discussed herein, nor shall there be any offer, solicitation, or sale of the securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

Item 8.01. Other Events.

On March 12, 2020, a purported shareholder class action complaint, McDermid v. Inovio Pharmaceuticals, Inc. and J. Joseph Kim, was filed in the United States District Court for the Eastern District of Pennsylvania, naming the Company and J. Joseph Kim, the Company’s Chief Executive Officer, as defendants. The lawsuit alleges that the Company made materially false and misleading statements regarding the Company’s development of a vaccine for COVID-19, also known as coronavirus, in its public disclosures in violation of certain federal securities laws. The plaintiff seeks unspecified monetary damages on behalf of the putative class and an award of costs and expenses, including reasonable attorneys’ fees. The Company intends to defend this action vigorously.
