Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

Insights
ATM capacity set at $18.88M; proceeds to issuer, 3% fee.
Clene updated its at‑the‑market facility, allowing issuance of common stock up to a maximum aggregate gross sales price of $18,880,000 through Canaccord as sales agent. This excludes $6,119,859 already sold under earlier supplements, indicating remaining capacity within the program.
Sales, if made, would deliver cash directly to the issuer, with Canaccord earning up to 3.0% per share sold. The company states it is no longer constrained by General Instruction I.B.6 for this S‑3, which can affect how much may be sold relative to public float.
Actual use of the ATM depends on market conditions and management decisions. Reference pricing in the excerpt shows CLNN at $8.89 on October 15, 2025, but execution levels will vary by trade.

Accordingly, we may offer and sell shares of our common stock having a maximum aggregate gross sales price of up to $18,880,000 from time to time through Canaccord, which does not include the shares of our common stock having a maximum aggregate gross sales price of $6,119,859 that were sold pursuant to the Prior Supplements to date.
