The filing for an offering of this size suggests that Nuwellis is seeking to raise capital, which could be used for various corporate purposes including operations, expansion, and debt repayment. However, such an offering typically dilutes existing shareholders' equity, which can lead to a negative short-term impact on the stock price. The confidence level is high due to the direct nature of the news, but not absolute as market conditions and investor sentiment can also influence the stock's reaction.
