Amendment Description This Amendment No. 1 on Form 10-K (“Amendment No. 1”) amends the Annual Report of BioSig Technologies, Inc. (the “Company”) on Form 10-K for the fiscal year ended December 31, 2021, as filed with the Securities and Exchange Commission on March 31, 2022 (the “Original Filing”). We are filing this Amendment to present the information required by Part III of Form 10-K that was previously omitted from the Form 10-K in reliance on General Instruction G(3) to Form 10-K because a definitive proxy statement containing such information will not be filed within 120 days after the end of the fiscal year covered by the Form 10-K. Accordingly, the reference on the cover page of the Form 10-K to the incorporation by reference of our definitive proxy statement into Part III of the Form 10-K has been removed.
