Suspension of ATM Offering; Termination of At The Market Offering Agreement

As previously reported, on June 23, 2025, EUDA Health Holdings Limited (“EUDA” or the “Company”) entered into an At The Market Offering Agreement (the “ATM Agreement”) with Chardan Capital Markets LLC (“Chardan”). The Company filed a prospectus supplement on each of June 24, 2025 and January 23, 2026 (each, the “Filed Prospectus Supplement”) relating to the offer and sale of up to $10,000,000 ordinary shares (the “Shares”) in an “at-the-market” offering (the “ATM Offering”) pursuant to the ATM Agreement. Each Filed Prospectus Supplement formed a part of the Company’s Registration Statement on Form F-3 (File No. 333-282723), which was filed with the Securities and Exchange Commission on October 18, 2024 and declared effective on November 4, 2024. On June 5, 2026, the Company sent Chardan a written notice to terminate the ATM Agreement. Pursuant to the terms of the ATM Agreement, this termination will take effect on July 22, 2026 (i.e., after thirty (30) business days from the date of the termination notice). In the meantime, the Company has suspended the ATM Offering, effective as of June 10, 2026. The Company will file a prospectus supplement reducing the number of Shares to be offered under the Filed Prospectus Supplements to zero. As of the date of this report, no ordinary shares have been sold under the ATM Agreement or the Filed Prospectus Supplements.
