SpacBrain’s read

Trust settled

The deal closed — SPAC shares became the target's shares, so there is no trust left to redeem (nobody missed a window; holders who wanted cash elected it at the vote).


In plain terms

What it is
A SPAC from DHIP Natural Resources Investments, LLC, listed on OTC in November 2021.
What it's doing now
It agreed to buy Uinta Infrastructure Group Corp., an Infrastructure company. That purchase completed, and it stopped being a SPAC — the shares became shares in the business it bought.
What you should know
This SPAC has finished. The purchase completed, and the shares became shares in the company it bought — anyone who wanted the cash instead asked for it at the vote, so there is no cash left here to claim and no deadline left to miss.

Nothing dated is on file. That is an absence in the record, not a statement that nothing is coming.

Yield to redemption

Nothing left to redeem — no yield to compute.

This SPAC has finished — its trust was paid back or used to close the deal, so there is nothing left to redeem and no yield to compute. A yield to redemption is a claim that you can hand these shares back for the trust cash. That account is closed, so this page will not print a number here.


What happened to the cash

The reasoning behind the verdict above, in the order the filings establish it.

  1. The deal closed — SPAC shares became the target's shares, so there is no trust left to redeem (nobody missed a window; holders who wanted cash elected it at the vote).

Each time shareholders were offered their cash back, some took it. Heavy cash-outs drain the account and shrink the number of shares left — whatever remains has to carry the deal.

The score

deterministic, from filed fields

IRRX is not in the scored universe, so no score is shown. A withheld score is a fact about the record, not a verdict about the company.

Asymmetric return scoreNeither a price nor a cash-per-share figure is on file for this vehicle, and the score is a ratio between the two. Nothing is estimated to fill the gap.

The score is only published for names that carry both a price and a filed cash-per-share figure — 292 of the tracked fleet today. The rest keep an empty dial rather than a modelled one, and fill in by themselves as the fields land.

The company

from SEC filings
Read the full profile

INTEGRATED RAIL & RESOURCES ACQUISITION CORP was a blank-check company (SEC SIC code 6770) whose common stock traded under the ticker IRRX on the OTC market.

(CIK 0002044112) carried item 2.01 (Completion of Acquisition) naming INTEGRATED RAIL & RESOURCES ACQUISITION CORP.


Material findings

from the full read of every filing

Every document this company files gets read whole — body and exhibits. These are the ones the read flagged as material, newest first, each citing its filing.

  • 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.

  • 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.

  • 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.

  • This SPAC is two full years past its original November 15, 2022 deadline and is now extending one month at a time, which is the profile of a vehicle kept alive for the sponsor's option rather than a deal about to close. The $50,000 monthly deposit spread across the remaining public shares adds little per share. Delegating further extensions to the board removes the recurring shareholder vote, and with it the recurring redemption window that has been holders' main protection.

  • Retaining the $5,000,001 net tangible asset limitation rather than amending it away, as most 2023 extension proxies do, gives holders a real protection: heavy redemptions abort the extension and trigger liquidation at trust value instead of leaving a hollowed shell. Redemption proceeds are calculated as the trust balance including interest not yet released for taxes, less up to $100,000 of net interest for dissolution expenses, divided by the outstanding public shares. This is a second extension for a vehicle already nine months past its original November 2022 deadline.

In plain English

tap a term to open it

Every piece of jargon this page could have used, and what it actually means.

Open the plain-English guide
No floor / floorlessthe cash guarantee is gone — the price is unprotected

A SPAC's downside protection is not the cash in trust; it is your right to demand that cash. Once the redemption window closes, the cash stays with the company and the share can trade anywhere.

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.

Broker action datethe day your broker needs the instruction — earlier than the official date

Brokers batch redemption instructions to the transfer agent, so the practical cutoff is roughly two business days before the published deadline. This is the date that actually costs people the floor.

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.

Trust discountbuying below the cash held for you

Only meaningful while a redemption right exists. On a floorless name the same arithmetic is not a discount, it is the market pricing distress, and this product will not call it a yield.

Dilutionhow much of the company new shares take from you

Sponsor promote, PIPE shares, warrants and rights all issue stock that did not pay $10 for it. The headline deal value is before that; the effective value is after.

Pro-forma equitywhat the company is valued at once the deal closes

The combined company's equity value assuming the announced terms and the redemptions that have actually happened.

ARShow much upside you get per unit of downside

SpacBrain's asymmetric-return score. It is deterministic — the same inputs always produce the same number — and it is capped, not zeroed, when the floor is gone.

De-SPACthe day the SPAC becomes the real company

The shares stop being a claim on a pot of cash and start being equity in an operating business. Roughly 80% of recent de-SPACs traded below $10 within a year.

Outside datethe contractual long-stop for closing the deal

A deadline between the SPAC and its target, not between the SPAC and you. It confers no right to cash, which is exactly why it must never be counted as a redemption window.

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.

Accreted NAV (estimate)the last filed cash figure, plus the interest it should have earned since

A model, not a filing: last filed value compounded at the 3-month T-bill for the days elapsed. Always shown in italic with the word estimate, and never printed beside a filed number without it.
