What changed: Integrated Rail and Resources Acquisition Corp. called a special meeting for September 15, 2025 at 10:00 a.m. Eastern Time by live webcast to extend the date to complete an initial business combination from the September 15, 2025 Termination Date to December 31, 2025, by depositing $1.00 into the Trust Account for that extension on or prior to September 15, 2025. The IPO closed November 16, 2021 and the charter originally required completion by November 15, 2022, with extensions approved at meetings on February 8, 2023 and February 8, 2024. Why it matters: The extension payment is one dollar in total - not per share - so holders are being asked to grant three and a half more months for no economic consideration whatsoever, the least accretive extension structure possible. Nearly four years past its IPO with a merger agreement signed thirteen months earlier and still unclosed, the risk is that the trust simply erodes through taxes and expenses. Redemption at trust remains the only certain outcome.

What changed: Integrated Rail and Resources Acquisition Corp. called a special meeting for July 15, 2025 at 10:00 a.m. Eastern Time by live webcast to extend the date to complete an initial business combination from the July 15, 2025 Termination Date to August 15, 2025 by depositing $1.00 into the Trust Account, and to allow further monthly extensions without another stockholder vote. The IPO closed November 16, 2021 and the charter originally required completion by November 15, 2022, with prior extensions approved at meetings on February 8, 2023 and February 8, 2024. Why it matters: An extension payment of one dollar in total, plus authority for the board to keep extending monthly without returning to shareholders, effectively removes the deadline as a protection - holders lose the periodic redemption vote that gives a SPAC its discipline. Excluding sponsor Class A shares from the redemption calculation does at least preserve the full trust for public holders. Redemption at this meeting is the last guaranteed exit before that discretion begins.

What changed: Integrated Rail and Resources Acquisition Corp. called a special meeting for Tuesday, May 13, 2025 at 10:00 a.m. Eastern Time, virtual, on an Extension Amendment moving the Termination Date from May 15, 2025 to June 15, 2025 in exchange for depositing $5,000 into the Trust Account on or before May 15, 2025, and permitting further monthly extensions without another stockholder vote. A separate NTA Amendment would remove the restriction barring redemptions that leave net tangible assets below $5,000,001. A Merger Agreement with Uinta Integrated Infrastructure was signed August 12, 2024. Why it matters: A $5,000 monthly extension payment is nominal — it adds essentially nothing per share to trust, so unlike a real deposit-funded extension this one shifts time to the sponsor at no cost to them and no benefit to holders. Removing the $5,000,001 net tangible asset floor eliminates the backstop that would otherwise stop redemptions from hollowing the company out, clearing the way for the Uinta deal to close with almost no cash. Redemption remains the safe election.

In plain English
Redemption deadlinethe last day to hand shares back for cash
Set by the filing that calls the meeting. Tender after it and the company is under no obligation to pay you the trust value.
Cash in trust / trust per sharethe cash the company is holding for each public share
Filed quarterly in the 10-Q's XBRL. It earns interest between filings, so the figure on a given day is slightly higher than the last filed one — where we show that we label it an estimate.
Accession numberthe SEC's unique id for one filing
Every figure on this page carries the accession of the filing that states it, so you can open the primary document rather than trust us.
