Navidea Biopharmaceuticals Regains Commercialization and Distributions Rights in Europe for LYMPHOSEEK®

Navidea Biopharmaceuticals, Inc. (NYSE American: NAVB) ("Navidea” or the "Company”), a company focused on the development of precision immunodiagnostic agents and immunotherapeutics, is pleased to announce that the Company has regained the commercialization and distribution rights in Europe for LYMPHOSEEK® (technetium Tc99m tilmanocept) injection from Norgine B.V. ("Norgine”). Navidea and Norgine have decided, by mutual agreement, to end the existing license agreement ("Agreement”) between the two companies.

The Agreement was originally entered in March 2015, and provided Norgine with the exclusive rights in Europe for LYMPHOSEEK. As a result of today’s transaction, Navidea has regained all the rights, economics, and intellectual property of LYMPHOSEEK in Europe.

Per this new agreement, both companies will cooperate to complete a seamless transfer of regulatory marketing authorizations back to Navidea. Through the transition, Norgine will remain responsible for the continued commercialization and distribution of LYMPHOSEEK in Europe for a period of six months.

Jed Latkin, CEO of Navidea, commented, "We would like to thank Norgine for our legacy partnership and initiating the commercialization and distribution in Europe. I am delighted that LYMPHOSEEK’s European rights and economics are now fully in the hands of Navidea. We are excited about the potential for this asset in Europe and will work to mirror the product’s successful and broad-based commercial adoption in the United States.”

Management plans to address the new agreement during the Company’s First Quarter 2020 Earnings Conference Call, scheduled for Thursday, May 14, 2020 at 5:00 p.m. (EDT). Conference call and webcast details can be found below.

Additionally, the Company has finalized the previously announced $4.2 million financing related to the judgement by the Ohio Court of Common Pleas (the "Judgement”). Navidea has agreed to issue Keystone Capital Partners, LLC, an existing shareholder, up to $4.2 million of mandatory redeemable preferred shares. These preferred shares are guaranteed by a portion of the proceeds of the Judgement.
