1. Business Organization, Nature of Operations and Basis of Presentation

Provectus Biopharmaceuticals, Inc., a Delaware corporation (together with its subsidiaries, “Provectus” or “the Company”), is a clinical-stage biotechnology company developing immunotherapy medicines for different diseases. Our drug product candidates are based on bioactive, synthetic, small molecule rose bengal sodium (“RBS”), which is a member of a class of molecules called halogenated xanthenes (“HXs”).

The Company’s proprietary, patented, pharmaceutical-grade RBS is the active pharmaceutical ingredient (“API”) in all our clinical development and non-clinical research programs. The Company is the first entity to advance RBS into clinical trials for the treatment of disease. The Company is also the first entity, and currently the only one, to date to make pharmaceutical-grade RBS API consistently at a purity of nearly 100%.

RBS can be delivered by different routes of administration. RBS may concurrently display stimulatory and inhibitory effects and may target disease in a bifunctional multi-modal manner. Direct contact by RBS with disease may lead to cell death or repair by one or more targeting mechanisms, depending on the disease being treated and the concentration of RBS being utilized in the formulation. Multivariate innate and adaptive immune activation, signaling, and response may follow.

The Company’s RBS drug platform and pipeline comprise drug product candidates and non-clinical formulations that use different amounts of RBS and are delivered by different routes of administration specific to each disease area, including:

Risks and Uncertainties

The Company’s activities are subject to significant risks and uncertainties, including failing to successfully develop and license or commercialize the Company’s prescription drug candidates.

Changes in U.S. Trade Policies Could Adversely Affect Our Operations

Ongoing uncertainty around U.S. trade policies, tariffs, and international agreements may impact the cost and availability of materials, supplies, and equipment used in our operations or those of our partners. Any disruptions or increased costs resulting from these changes could negatively affect our business, financial condition, results of operations, and the market price of our common stock.
