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 Public Offering. B. Riley Principal Sponsor Co., LLC, listed on NYSE in April 2019.
What it's doing now
It agreed to buy ALTA EQUIPMENT GROUP INC., an equipment dealership and rental services 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.

Cash held per sharenot filed for this window

This vehicle has finished, so there is no window to file a cash-per-share figure for and none will follow. No estimate is shown in its place.

Next date that mattersno dated event on file

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).

The score

deterministic, from filed fields

ALTG 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

B. Riley Principal Merger Corp. was a blank-check company whose common stock traded on the New York Stock Exchange under the ticker ALTG and was assigned SEC CIK 0001759824 and SIC industry code 5084. The company priced its initial public offering on April 9, 2019, as reflected in a 424B4 prospectus filed under SEC file number 333-230286, which corresponded to the S-1 registration statement filed on March 14, 2019. The vehicle completed a business combination and no longer files, with the closing evidenced by a Form 25 filed on April 12, 2021, under which the company's warrants—each exercisable for one share of Class A common stock at $11.50 per share—came to evidence other securities in substitution therefor. The successor registrant, Eos Energy Enterprises, Inc. (EOSE, EOSEW; CIK 0001805077), filed an 8-K carrying Item 2.01 (Completion of Acquisition) naming B. Riley Principal Merger Corp., and EDGAR now lists the original CIK under the name ALTA EQUIPMENT GROUP INC.

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.

  • DEF 14A15 April 20260001193125-26-157108opens on sec.gov in a new tab

    An amendment to the omnibus plan asks holders to enlarge an equity pool that already carries nearly a million units for two executives alone, at a $5.24 share price where each dollar of award value buys far more shares than it did at issue. Director RSUs are also struck off a trailing VWAP, so the share count expands faster as the price falls - the dilution mechanism compounds weakness rather than rewarding recovery.

  • DEFM14A23 January 20200001213900-20-001644opens on sec.gov in a new tab

    Three conditions must all be met: debt financing, Alta EBITDA of at least $72.5 million, and at least $143 million of cash available from the trust account and equity financing sources — so redemptions can break this deal outright. Against that, $25,000,000 of forward purchase units at $10.00 is committed by a sponsor affiliate regardless of redemptions, plus $35,000,000 of PIPE shares. The inducement is paid by the sponsor: PIPE investors receive 178,947 extra shares and 1,275,000 warrants, and the Sponsor forfeits matching founder shares plus a further 1,470,855.

  • PREM14A13 December 20190001213900-19-026160opens on sec.gov in a new tab

    Closing turns on three conditions rather than the vote alone: BRPM must obtain the debt financing, must have at least $143 million of cash available from the trust account and equity financing sources, and Alta's EBITDA must be at least $72.5 million. Alta's equityholders receive $119 million — $43 million in cash and $76 million of stock, or 7,600,000 shares valued at $10.00 per share — while roughly $295 million of Alta's gross debt is repaid. The cash test is supported by a $25,000,000 forward purchase at $10.00 per unit and $35,000,000 of PIPE subscriptions at $10.00 per share.

Everything this company has filed with the SEC recently, newest first, each with a plain summary of what changed and why it matters.

  • 314 August 20260001193125-26-352539opens on sec.gov in a new tab
  • 8-K6 August 20260001193125-26-338061opens on sec.gov in a new tab

    What changed: Alta Equipment Group (ALTG) reported Q2 2026 results: total revenues of $475.5M (down $5.7M YoY), Adjusted EBITDA of $48.6M (up $0.1M YoY), and net loss of $(8.2)M. The company tightened full-year 2026 Adjusted EBITDA guidance to $167.5M–$177.5M and reduced interest expense by $2.8M YoY to $19.5M. Why it matters: This is a routine post-combination earnings release for a closed SPAC; no redemption, extension, or trust-related events are involved. Operating performance shows modest sequential improvement but continued net losses and negative stockholders' equity of $(36.2)M.

  • 10-Q6 August 20260001193125-26-338075opens on sec.gov in a new tab

    What changed: Alta Equipment Group (ALTG) filed a routine 10-Q for Q2 2026, reporting a net loss of $7.5 million on $475.5 million in revenue. The company completed a small divestiture of a New England battery shop for $1.5 million and its related party OneH2 entered an assignment for the benefit of creditors on June 24, 2026. Why it matters: This is a standard quarterly report for an operating company with no SPAC trust, redemption deadline, or extension mechanics involved. The OneH2 assignment for the benefit of creditors and the $5.3 million Hydrogen Plant investment are notable but immaterial to the overall financials.

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.

UNIVERSE-IPO-INDEX2026-08-17

admitted from EDGAR's QUARTERLY FORM INDEX, walked without any SIC filter. The SIC 6770 census could not reach this registrant: EDGAR reassigns a shell's SIC the day it stops being one, and this CIK now files under 5084 (Wholesale-Industrial Machinery & Equipment). The screen found it by filing SHAPE instead — S-1 2019-03-14 → 8-A12B 2019-04-05 → 424B4 2019-04-09 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts. SIC 5084 + self-described blank check in 424B4 0001615774-19-005543; 424B 0001615774-19-005543 priced 2019-04-09 under S-1 0001615774-19-004062 (file 333-230286, an offering for cash); common ticker ALTG off 8-K 0001564590-21-017555 (2021-04-05); lifecycle EXITED. The pricing prospectus was filed under SEC file number 333-230286, which belongs to S-1 0001615774-19-004062 (2019-03-14) — a registration of shares sold for CASH, which is what makes it an IPO rather than merger consideration. Blank-check status from the registrant's own first-person sentence in that prospectus (EDGAR full-text search, 424B4 2019-04-09). Ending PROVEN, not inferred: CLOSED per Form 25 0000876661-21-000536 (2021-04-12) — Form 25 filed under 17 CFR 240.12d2-2(a)(3) — the rule for securities that "have come to evidence other securities in substitution therefor", i.e. the shares became the successor's (class: Warrants, each whole warrant exercisable for one share of Class A common stock, each at an exercise price of $11.50 per share); the successor registrant Eos Energy Enterprises, Inc. (EOSE, EOSEW) (CIK 0001805077) filed an 8-K carrying item 2.01 (Completion of Acquisition) naming "B. Riley Principal Merger Corp." — the SPAC merged into a new registrant and so filed no closing report of its own. EDGAR now files this CIK as "ALTA EQUIPMENT GROUP INC." — the SPAC's own name is kept here and the successor is the target. ipoSizeM and deadline left NULL: gross-proceeds prose conflates the over-allotment with the offering, and a charter deadline belonging to a vehicle that has ended is a date nobody can act on. ipoDate is the 424B pricing date.
