Inovio Pharmaceuticals, Inc. (the “Company”) is providing the following financial information. As of June 30, 2026, the Company estimates that its cash and cash equivalents were approximately $36.7 million.

The cash and cash equivalents information above is based on preliminary unaudited information and management estimates for the quarter ended June 30, 2026, is not a comprehensive statement of our financial results as of and for the quarter ended June 30, 2026, and is subject to completion of the Company’s financial closing procedures.

The preliminary financial data included in this current report has been prepared by, and is the responsibility of, the Company’s management. Ernst & Young LLP has not audited, reviewed, examined, compiled, nor applied agreed-upon procedures with respect to the preliminary financial data. Accordingly, Ernst & Young LLP does not express an opinion or any other form of assurance with respect thereto.

The information in this Current Report on Form 8-K is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section. The information in this Current Report on Form 8-K shall not be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.
