GridAI Technologies Corp. 8-K filed 2026-09-11

GridAI Technologies Corp. filed a Form 8-K on 2026-09-11 under Item 1.01, Entry into a Material Definitive Agreement. The company trades as GRDX on Nasdaq, is classified under Electric & Other Services Combined, and is listed as a non-accelerated filer and smaller reporting company. Its former names include Entero Therapeutics, Inc., First Wave BioPharma, Inc., AzurRx BioPharma, Inc. and BioPharma d'Azur, Inc. The filing updates a loan GridAI made to Pronghorn Resources, LLC, a Delaware limited liability company, which the company first reported in an 8-K filed on July 23, 2026. That original loan was made under a Secured Convertible Promissory Note with a principal sum of $2,000,000. On September 4, 2026, the two parties entered into an Amended and Restated Secured Convertible Promissory Note to reflect a second loan of an additional $964,000. On the same date they signed a First Amendment to the Security Agreement, which updates the Security Agreement dated July 17, 2026 so that it covers the amended note. The amended note, attached as Exhibit 10.1, states a Principal Amount of $2,964,000. It is due on the earlier of December 31, 2026 or the consummation of a Change of Control Transaction. One of the events that counts as a change of control is someone acquiring effective control of in excess of 50% of Pronghorn's voting securities. The note is secured, and it carries a legend stating that neither it nor the securities it converts into have been registered under the Securities Act of 1933. The filing is signed by Jason D. Sawyer, Chief Executive Officer. For an analyst or journalist, the main point is that GridAI has increased its secured, convertible lending to a single counterparty to $2,964,000, with a short maturity. The interest rate, the conversion price and terms, the collateral, the purpose of the loans, Pronghorn's business, and any relationship between the parties beyond this note are not in the filing excerpt provided here.
