[Form 3] Salarius Pharmaceuticals, Inc. Initial Statement of Beneficial Ownership

Rhea-AI Filing Summary

Salarius Pharmaceuticals, Inc. (SLRX) filed an initial Form 3 for its Chief Scientific Officer, reporting only derivative securities. The reporting person holds Series A Preferred Stock that is convertible into 141,734 shares of common stock. The Series A Preferred has no expiration date and will convert automatically into common shares after stockholder approval and satisfaction of specified Nasdaq listing standards.

The filing also reports two stock options for common stock: one covering 5,061 shares with an exercise price of $4.9369 per share and another covering 8,318 shares with an exercise price of $50.2579 per share. Both option grants become exercisable only after stockholder approval and satisfaction of certain Nasdaq listing standards, so their potential value depends on these conditions being met.
