Tether Global Investments Acquires 9.99% Stake in Stablecoin Development Corp via Warrants

On May 22, 2026, Tether Global Investments Fund, S.I.C.A.F., S.A., along with its subsidiary Tether Investments, S.A. de C.V. and Giancarlo Devasini, filed a Schedule 13G disclosing a new 9.99% stake in Stablecoin Development Corp (Ticker: NBY). The reporting persons reported beneficial ownership of 3,009,502 shares of common stock, which are issuable upon the conversion of warrants held by Tether Investments. The filing specifies that the total number of shares issuable upon conversion is subject to an ownership limitation, which prevents the reporting persons from holding more than 9.99% of the issued and outstanding common stock. Consequently, they disclaimed beneficial ownership of an additional 5,740,498 shares that would otherwise be convertible under the warrants. Giancarlo Devasini, who holds a majority voting interest in the fund, is deemed to have shared voting and dispositive power over the securities. The acquisition was made for investment purposes and not to influence control of the issuer.
