On June 30, 2025, Integrated Rail and Resources Acquisition Corp.

At the Special Meeting, SPAC stockholders approved a proposal (a) to approve and adopt the Agreement and Plan of Merger (as amended by that certain Amendment to and Waiver of Agreement and Plan of Merger, dated November 8, 2024, as further amended by that certain Second Amendment to Agreement and Plan of Merger, dated December 31, 2024, as further amended by that certain Waiver to Agreement and Plan of Merger, dated April 30, 2025, and as further amended by that certain Third Amendment to Agreement and Plan of Merger, dated May 14, 2025, the “Merger Agreement”), by and among (i) Integrated Rail and Resources Acquisition Corp., (ii) Uinta Infrastructure Group Corp.
