Item 8.01 Other Events.

RYVYL Inc. ("RYVYL" or the "Company") announced that the Special Meeting of Shareholders (the "Special Meeting") to vote on the Company's planned merger with RTB Digital, Inc. ("Roundtable"), which was convened on March 18, 2026, has been adjourned.

The Special Meeting is now scheduled to reconvene virtually on March 25, 2026, starting at 4pm EST. Shareholders interested in participating in the reconvened Special Meeting should use the following link:

http://www.virtualshareholdermeeting.com/RVYL2026SM

The record date for the Special Meeting, February 6, 2026, is unchanged and applies to the reconvened Special Meeting.

To date, approximately 99% of the votes cast, voted in favor of the proposed merger, with 43% of the entitled to vote submitted, therefore only 7% additional votes in favor are needed to confirm the merger. The Company is in recess to complete collection of the additional votes. For shareholders who are yet to cast their votes, we urge them to vote their shares now, so they can be tabulated prior to the reconvened Special Meeting.

For questions or voting assistance, please contact Kingsdale Advisors at 888-518-6812 or [email protected].
