Navidea Biopharmaceuticals Reports Second Quarter and Year-to-Date 2020 Financial Results

Navidea Biopharmaceuticals, Inc. (NYSE American:NAVB) ("Navidea" or the "Company"), a company focused on the development of precision immunodiagnostic agents and immunotherapeutics, today announced its financial results for the second quarter and year-to-date for the period ended June 30, 2020.

"The past four months have been truly momentous for the company. The successful second interim look showed how valuable our diagnostic agent will be for the effective management of Rheumatoid Arthritis," said Mr. Jed A. Latkin, Chief Executive Officer of Navidea. "The signing of the binding MOU with Jubilant is a transformational event for the future of Navidea. Partnering with the second largest radiopharmaceutical company in the United States and a global leader in pharmaceuticals is something we have worked hard to achieve for many years. Furthermore, the $25 million in growth capital pledged by a top-notch syndicate of investors has assured the company's non-RA related growth funding for years to come."

Second Quarter 2020 Highlights and Subsequent Events

• Executed a binding memorandum of understanding ("MOU") on August 9, 2020 with Jubilant Draximage Inc. dba Jubilant Radiopharma, Radiopharmaceuticals Division ("Jubilant"). The MOU outlines the terms and framework for an Exclusive License and Distribution Agreement for Navidea's Rheumatoid Arthritis Diagnostic in the United States, Canada, Mexico, and Latin America. In connection with the MOU, Jubilant made a $1 million equity investment in exchange for a limited exclusivity period while final due diligence efforts are completed.
• Signed a binding commitment letter on August 9, 2020 with Mastiff Group LLC, for a private placement financing of up to $25 million in aggregate gross proceeds of shares of Navidea's common stock, to be priced either "at the market" or at a premium to Navidea's closing price on the date of execution. Navidea expects to sign definitive documents for a common stock only transaction, with an investor syndicate comprised of Mastiff Group LLC, John Kim Scott, Jr. and other fundamental biotech focused investors no later than August 18, 2020, with the closing to take place within 15 business days thereafter.
• Regained the commercialization and distribution rights for Lymphoseek^® (Tc99m tilmanocept) injection in Europe through the mutually agreed upon termination of the perpetual license agreement with SpePharm AG, a subsidiary of Norgine B.V.
• Finalized the previously announced $4.2 million financing related to the judgment by the Ohio Court of Common Pleas (the "Judgment"). Navidea agreed to issue Keystone Capital Partners, LLC, up to $4.2 million of convertible preferred shares, which will be guaranteed by a portion of the proceeds of the Judgment.
• Announced positive preliminary results from the Company's second interim analysis of its ongoing NAV3-31 Phase 2b study. Analysis demonstrated that these interim data further corroborate Navidea's hypotheses that Tc99m tilmanocept imaging can provide robust, quantitative imaging in healthy controls and in patients with active rheumatoid arthritis ("RA"), and that this imaging can provide an early indicator of treatment efficacy in patients with active RA.
• Achieved full enrollment in its ongoing NAV3-31 Phase 2b study titled "Evaluation of the Precision and Sensitivity of Tilmanocept Uptake Value (TUV) on Tc99m Tilmanocept Planar Imaging." All of the subjects have been enrolled in the three-arm trial, with the protocol-specified longitudinal imaging events on track.
• Presented results from the Company's first interim analysis of its ongoing NAV3-31 phase 2b clinical study, titled, A Phase 2b Study of Intravenously Administered Tc 99m Tilmanocept to Determine Differential Uptake, Reproducibility Over Time and Image Stability in Healthy Subjects and in Patients with Rheumatoid Arthritis ("RA") on Stable Treatment, at the European League Against Rheumatism ("EULAR") Congress 2020.
• Continued enrollment in the Investigator Initiated Phase 2 trial being run at the Massachusetts General Hospital evaluating Tc99m tilmanocept uptake in atherosclerotic plaques of HIV-infected individuals.
• Filed a provisional patent on improved synthesis of Tilmanocept.
• Received a one-year extension on its NIH phase 1 Small Business Technology Transfer grant (1R41HL147640-01A1) entitled Gallium 68 Tilmanocept for PET Imaging of Atherosclerosis Plaques, due to COVID-19 related shutdown of the research facility at the University of Alabama Birmingham. The site has reopened and these preclinical studies are ongoing.

Michael Rosol, Ph.D., Chief Medical Officer for Navidea, said, "The clinical research team continues to work diligently to advance the technology in key disease areas, with an emphasis on our RA program. Our currently running Phase 2b trial in RA is proceeding well and, building upon the interim analysis results, we are preparing to discuss the upcoming Phase 3 with the FDA. We are also preparing for the start of our second Phase 2b trial comparing tilmanocept imaging to synovial tissue biopsy samples of RA patients."

Financial Results

• Total revenues for the second quarter 2020 were $271,000, compared to $260,000 for the same period in 2019. Total revenues for the first half of 2020 were $427,000, compared to $302,000 for the same period in 2019. The increases were primarily due to increased grant revenue related to Small Business Innovation Research grants from the National Institutes of Health supporting Manocept development.
• Research and development ("R&D") expenses for the second quarter of 2020 were $1.3 million, compared to $1.1 million in the same period in 2019. R&D expenses for the first half of 2020 were $2.3 million, compared to $1.8 million in the same period in 2019. The increases were primarily due to net increases in drug project expenses, including increased Manocepttm diagnostic development costs offset by decreased Manocept therapeutic development costs, coupled with increased employee compensation.
• Selling, general and administrative ("SG&A") expenses for the second quarter of 2020 were $1.3 million, compared to $1.9 million in the same period in 2019. SG&A expenses for the first half of 2020 were $3.2 million, compared to $3.6 million in the same period in 2019.
