Nyxoah SA (the “Company”) mistakenly filed with the Securities and Exchange Commission (the “SEC”) a Form 6-K
for the month of September 2025 (the “Unauthorized Original Form 6-K”). The filing of the Unauthorized Original Form
6-K was not approved by the Company or the Company’s outside counsel and should be disregarded. The Company is filing this

Unauthorized Original Form 6-K contained drafts of disclosure and documents referencing a potential transaction. No transaction
was launched or consummated and none of the documents referenced were entered into or issued. The Company continues to evaluate
market conditions, its cash needs and business outlook and, as disclosed in the Company’s Annual Report on Form 20-F for fiscal
year ended December 31, 2024, and in subsequent filings with the SEC, will continue to seek additional capital, including through equity
and debt financing.

The information included under the heading “Nyxoah SA” shall be deemed to be incorporated by reference into the Company’s registration statements on Form S-8 (Registration Numbers 333-261233, 333-269410, 333-283103 and 333-285960) and Form F-3 (Registration Numbers 333-268955 and 333-285982) (including any prospectuses forming a part of such registration statements) and is a part thereof from the date on which this report is filed, to the extent not superseded by documents or reports subsequently filed or furnished.
