       Risk Factors  Investing in our securities includes a high degree of risk. You should consider carefully the specific factors discussed below, together with all of the other information contained in our SEC filings. If any of the following risks actually occurs, our business, financial condition, results of operations and future prospects would likely be materially and adversely affected. This could cause the market price of our securities to decline and could cause you to lose all or part of your investment. Risks include but are not limited to:We have a limited history of operations and limited experience in sales and marketing, and we might be unsuccessful in increasing our sales and cannot assure you that we will ever generate substantial revenue or be profitable. We have incurred operating losses since our inception and anticipate that we will continue to incur operating losses in the near-term.Our near-term prospects are highly dependent on revenues from a single product, the Aquadex system. We face significant challenges in expanding market acceptance of the Aquadex system, whichcould adversely affect our potential revenues.We have limited commercial manufacturing experience and could experience difficulties in producing commercial volumes of the Aquadex system and related components or may need to depend on third parties for manufacturing.We believe that we will need to raise additional capital to fund our operations. If additional capital is not available, we will have to delay, reduce or cease operations.We depend upon third-party suppliers, including single-source suppliers, making us vulnerable to supply problems and price fluctuations.If we cannot develop adequate distribution, customer service and technical support networks, then we may not be able to market and distribute the Aquadex system effectively and our sales will suffer.We may face significant risks associated with international operations, which could have a material adverse effect on business, financial conditions and results of operations.The COVID-19 pandemic and other public health threats or outbreaks of communicable diseases could have a material adverse effect on our operations and overall financial performanceWe are a “smaller reporting company” under federal securities laws and the company cannot be certain whether the reduced reporting requirements applicable to such companies will make the common stock less attractive to investors.  FOR INVESTOR PURPOSES ONLY: NOT FOR PRODUCT PROMOTION ©2021 Nuwellis, Inc.  3
