Macrophage Therapeutics, a Subsidiary of Navidea Biopharmaceuticals, Executes Securities Purchase Agreement for $2.5 Million Financing and Receives Initial Funding

DUBLIN, Ohio--(BUSINESS WIRE)-- Macrophage Therapeutics, Inc., a subsidiary of Navidea Biopharmaceuticals, Inc. (NYSE MKT: NAVB), today announced definitive agreements have been executed for its previously announced $2.5 million round of standalone financing and the funding process is underway. The proceeds will be used for pipeline development, general working capital and recruitment of a scientific advisory board that will counsel and recommend the initial therapeutic applications of Navidea’s Manocept™ platform technology.

“This financing provides the capital that enables us to work with some of the best scientific and medical experts in macrophage mediated-diseases and to prioritize and more aggressively advance important therapeutic applications with the Manocept platform,” stated Michael Goldberg, M.D., Macrophage Therapeutics Chief Executive Officer. “These funds will allow us to generate additional foundational data and secure the relevant intellectual property so we can establish the partnerships necessary to advance the large number of potential therapeutics expeditiously.”

The transaction was led by Platinum-Montaur Life Sciences and Dr. Goldberg. The first draw of $500,000 has been initiated. Should the entire $2.5 million be funded, there will be issued and outstanding a total of 50 shares of preferred stock and warrants to purchase 1,500 shares of common stock, representing a 1% interest in Macrophage Therapeutics on a fully converted and exercised basis. In the event that Macrophage Therapeutics has not completed a public offering of in excess of $50 million by March 11, 2017, each share of preferred stock in Macrophage Therapeutics will become exchangeable for common stock of Navidea based on the stock price of Navidea at 80% of the then-current volume weighted average price per share of Navidea stock, but not less than $3. If the investors do not timely exercise their exchange option, Macrophage Therapeutics can redeem the preferred stock for a price equal to 1.1664 times the initial issue price. Based on the expected enterprise valuation of $500 million, shareholders of Navidea will retain 99.0% ownership of Macrophage Therapeutics assuming full conversion of the preferred stock and exercise of the warrants.

“This funding will put us in a favorable position to more rapidly drive the Manocept platform towards its ultimate value, while ensuring that existing Navidea shareholders retain the vast majority of the ownership,” said Rick Gonzalez, Navidea Chief Executive Officer. “We believe the work being done with the Manocept technology opens the door to important new diagnostic opportunities for Navidea as well as therapeutics to be developed by Macrophage Therapeutics.”
