Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On July 10, 2026, the Board of Directors (the "Board") of Fermi Inc. (the "Company") received a letter from Mr. Miles Everson, a director designee of Toby Neugebauer, pursuant to which Mr. Everson resigned as a director of the Company, effective immediately (the "Resignation Letter"). At the time of his resignation, Mr. Everson did not serve on any committee of the Board.

In the Resignation Letter, Mr. Everson stated that his resignation was due to a disagreement with the Company over his access to certain books and records of the Company and the Board's decision to delegate to the Finance Committee of the Board (the "Finance Committee") responsibility for overseeing the negotiation and approval of certain financing transactions.

The Company believes that Mr. Everson was granted full access to the Company's books and records, except for materials relating to pending litigation involving Mr. Neugebauer, for whom Mr. Everson served as a Board representative. Mr. Everson also approved the Board's establishment of the Finance Committee and the delegation of responsibility to the Finance Committee for overseeing the negotiation and approval of certain financing transactions.

A full and complete copy of the Resignation Letter is attached hereto as Exhibit 17.1 to this Current Report on Form 8-K (this "Form 8-K"). All descriptions of the contents of the Resignation Letter set forth in this Form 8-K are qualified in their entireties by reference to the full text of the Resignation Letter.
