Rhea-AI Filing Summary

Atossa Therapeutics, Inc. released an updated corporate presentation that includes a preliminary estimate of its cash and cash equivalents. The company estimates it held approximately $40 million in cash and cash equivalents as of December 31, 2025.

This cash figure is unaudited, based on internal closing procedures for the fourth quarter and full year 2025, and may change once final results are completed. Atossa stresses that this estimate alone does not provide a full picture of its financial condition or results of operations and cautions investors not to place undue reliance on it.

The presentation also discusses forward-looking expectations for the development and potential regulatory path of the company’s lead program, (Z)-Endoxifen, including possible indications, approval prospects and market opportunities, all of which are subject to significant clinical, regulatory, financing and Nasdaq listing-compliance risks.
