Explanatory Note

On August 20, 2025, Sanuwave Health, Inc. (the “Company”) filed a Current Report on Form 8-K (the “Form 8-K”) disclosing the voting results at the Company’s 2025 annual meeting of stockholders held on August 19, 2025 (the “Annual Meeting”). The sole purpose of this amendment (this “Amendment”) to the Form 8-K is to disclose, in accordance with Item 5.07(d) of Form 8-K, the Company’s decision as to how frequently the Company will conduct future stockholder advisory votes on the compensation paid to the Company’s named executive officers. No changes are being made to the Form 8-K, other than to add the disclosure set forth in this Amendment.

Item 5.07    Submission of Matters to a Vote of Security Holders.

At the Annual Meeting, the Company’s stockholders voted on, among other matters, an advisory vote regarding the frequency of future votes on the compensation paid to the Company’s named executive officers. The frequency of every one year received the highest number of votes cast by stockholders, consistent with the recommendation of the Company’s Board of Directors. On January 7, 2026, the Company’s Board of Directors determined that the Company will hold a stockholder advisory vote on the compensation paid to the Company’s named executive officers every one year, until the next stockholder advisory vote on the frequency of future votes on the compensation paid to the Company’s named executive officers, which will occur no later than the Company’s 2031 annual meeting of stockholders.
