Section 5 – Corporate Governance and Management

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

ALT5 Sigma Corporation (the “Company”, “we”, “our”, or “us”) changed its corporate name from ALT5 Sigma Corporation to AI Financial Corporation on April 28, 2026, as of 11:59 pm PDT. We also changed our Nasdaq common stock ticker symbol from “ALTS” to “AIFC” as of the opening of the market on April 29, 2026. The name change was effected through a parent/subsidiary short-form merger of AI Financial Corporation, our wholly-owned Nevada subsidiary formed solely for the purpose of effectuating the name change (the “Name Change Subsidiary”), whereby it merged with and into the Company, with the Company being the surviving entity. In preparation for the name-change merger, we filed Articles of Incorporation of the Name Change Subsidiary with the Secretary of State of the State of Nevada on April 24, 2026. A copy of those Articles of Incorporation is attached hereto as Exhibit 3.23. Then, on April 28, 2026, to effectuate the name change, we filed Articles of Merger between the Name Change Subsidiary and us with the Secretary of State of the State of Nevada. A copy of the Articles of Merger is attached hereto as Exhibit 3.24. Our Board of Directors approved the name-change merger and, in accordance with Section 92A.180 of the Nevada Revised Statutes, approval by our stockholders was not required . Further, our website address changed from “alt5sigma.com” to “aifi.co.” No action by our stockholders was required with respect to the ticker symbol change. Our CUSIP number and transfer agent remain unchanged.

7.01. Regulation FD Disclosure.

On April 29, 2026, we issued a press release announcing our name and ticker symbol change. A copy of the press release is furnished as Exhibit 99.1 hereto.
