Item 1. Legal Proceedings.

United Dogecoin Inc., an entity wholly owned by the Company, has been sued by a former consultant, One Eyed Jack Enterprises LLC (“OEJE”), in connection with OEJE’s alleged work with United Dogecoin’s acquisition by our company in a case captioned, One Eyed Jack Enterprises LLC v. United Doge Coin Inc., pending in the Supreme Court of the State of New York, New York County, Index No. 653395/2026. OEJE seeks approximately $250,000 and 2.99% of United Dogecoin Inc.’s common stock or the equivalent in convertible preferred stock. United Dogecoin has moved to dismiss the complaint and is awaiting a decision. Based on its initial assessment, United Dogecoin believes the allegations lack merit and intend to defend against them; however, the matter is in the early stages of litigation and United Dogecoin can express no opinion as to the likely outcome of this matter. Other than as described above, we are not party to, and our properties and assets are not the subject of, any material legal proceedings.
