WINTER PARK, Fla., Dec. 12, 2025 (GLOBE NEWSWIRE) -- Integrated Rail and Resources Acquisition Corp., a Delaware corporation (“IRRX”) today announced the completion of its previously announced business combination with Tar Sands Holdings II, LLC, a Utah limited liability company (“TSII”). Upon closing, the combined company will operate under a new parent entity, Uinta Infrastructure Group Corp., a Delaware corporation (“UIGC”), marking the next step in advancing a long-planned infrastructure platform in the Uinta Basin. With the completion of the transaction, IRRX public shareholders who chose not to redeem their shares will become shareholders of UIGC. Outstanding IRRX warrants will be exchanged for UIGC warrants at a one-to one ratio under the terms of the parties’ Agreement and Plan of Merger. The business combination was approved at a special meeting of IRRX’s stockholders on June 30, 2025. Upon the closing of the business combination, trading of IRRX’s Class A common stock, warrants, and units will cease. UIGC, which will be led by Brian Feldott as Chief Executive Officer, is preparing to file an S-1 registration statement with the U.S. Securities and Exchange Commission to enable UIGC’s shares and warrants to list on a national stock exchange. The company intends to move through the filing and review process as efficiently as possible. In the period between closing and the effectiveness of the S-1, UIGC’s shares and warrants may not be eligible for trading on the OTC markets or any other exchange. UIGC is working to complete all necessary steps to list on a national stock exchange as soon as practicable. “We are pleased to reach this milestone and look forward to building on the platform established through this transaction,” said Mark Michel, Chairman of the Board of Directors. “Our focus now shifts to finalizing the registration statement and positioning the company for a new public listing.” Additional information will be provided by UIGC as the registration and listing process progresses.
