As a blank check company, IRRX used reports on Forms 8-K and other filings to disclose material events such as merger agreements, charter amendments, financing arrangements, and changes in management.
Among the notable filings are Current Reports on Form 8-K describing the Agreement and Plan of Merger among IRRX, Uinta Integrated Infrastructure Inc., Uinta Infrastructure Group Corp., Tar Sands Holdings II, LLC, and related parties, along with multiple amendments that extended the termination date of the merger agreement.
