Navidea Biopharmaceuticals, Inc. (NYSE:NAVB) ("Navidea" or the "Company"), a company focused on the development of precision immunodiagnostic agents and immunotherapeutics, today announced its continued and steadfast focus on moving the Company forward and leveraging its Fix Fund Propel approach while also intending to appeal potential delisting from the NYSE American Exchange.

Change Creates Opportunity

While the traditional exchange has been an integral part of Navidea's history, and the Company intends to appeal the potential delisting, its Fix, Fund Propel approach and focus would not change as a result of a transition from the Exchange. Instead, the Company may embrace potential new opportunities to deliver exceptional value to our stakeholders, including:

• Diverse Sources of Capital - The Company now has the unique advantage of exploring and more quickly tapping into a broader spectrum of capital sources tailored to Navidea's specific growth needs, ensuring the financial resources required to achieve its strategic objectives.
• Strategic Agility - As Navidea continues pursuing its ambitious Fix, Fund, Propel, approach, this transition allows the Company to operate with increased agility, removed from the constraints of short-term pressure, enabling focus on executing initiatives that drive growth in the market.

Company Studies and Trials Update
