See Note 9 for additional details regarding the recapitalization.

Redomestication and Name Change

In February 2026, the Company completed a statutory conversion and redomestication from the State of Delaware to the State of Texas. The redomestication became effective on February 10, 2026, upon the filing of the applicable conversion and formation documents with the Texas Secretary of State, at which time the Company ceased to be a Delaware corporation and continued its existence as a Texas corporation. The redomestication did not result in any change to the Company’s business, operations, assets, liabilities, or stockholders’ equity.

Effective March 19, 2026, the Company completed its corporate name change from Renewal Fuels, Inc. to American Fusion, Inc. and FINRA processed the related ticker symbol change from RNWF to AMFN.
