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, listed on Nasdaq in August 2021.
What it's doing now
It agreed to buy TIGO ENERGY, INC., a solar power electronics and smart energy management 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.

The score

deterministic, from filed fields

ROCG 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 — 294 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

Roth CH Acquisition IV Co. was a blank-check company whose common stock traded on the Nasdaq Stock Market under the ticker ROCG. The company priced its initial public offering on August 6, 2021, under SEC file number 333-257779, with shares registered for cash on S-1 accession 0001104659-21-090357 and a pricing prospectus filed as 424B4 accession 0001104659-21-101571. The registrant self-described itself as a blank-check company in that prospectus and carried SEC SIC industry code 3674 (Semiconductors & Related Devices). On May 22, 2023, the ticker ROCG appeared on the cover page of 8-K accession 0001104659-23-063152. The vehicle completed a business combination and no longer files, with its closed status established by 8-K accession 0001213900-23-044099 filed on May 30, 2023, reporting a change in shell company status under item 5.06; EDGAR now files SEC CIK 0001855447 under the name Tigo Energy, Inc.

    This summary is drawn from the cover page and cautionary note of the report; the financial statements are not covered here.

  • S-4/A20 April 20230001104659-23-047874opens on sec.gov in a new tab

    Those 60,000,000 shares are stated to be approximately 86.2% of the combined company's issued and outstanding shares immediately after closing on a fully diluted basis, leaving ROCG's own holders and sponsor with the remainder — and that figure assumes no public stockholder redeems and that L1 Energy does not convert the Convertible Note. The filing values the consideration at approximately $600.0 million using $10.00 per ROCG share, which it identifies as the price at which ROCG completed its initial public offering in August 2021, not a current market price.

  • S-4/A7 April 20230001104659-23-043194opens on sec.gov in a new tab

    The consideration is not fixed at 60,000,000: it is subject to a dollar-for-dollar upward or downward adjustment if Tigo raises or obtains a commitment to raise capital before the closing, excluding capital raised through convertible notes or similar debt instruments. The 86.2% fully diluted share of the combined company those shares are said to represent assumes no ROCG public stockholder redeems and that L1 Energy does not convert the Convertible Note. The $600.0 million equity value quoted rests on $10.00 per ROCG share, its stated August 2021 initial public offering price.

  • S-4/A14 February 20230001104659-23-020202opens on sec.gov in a new tab

    The 86.1% figure carries two assumptions on its face: that no ROCG public stockholder exercises redemption rights, and that L1 Energy does not exercise its right to convert the Convertible Note before the Closing. The consideration is also subject to a dollar-for-dollar upward or downward adjustment if Tigo raises or obtains a commitment to raise capital, excluding convertible notes and similar debt instruments. The $600.0 million equity value quoted for Tigo rests on $10.00 per ROCG share, the price at which ROCG completed its initial public offering in August 2021.

  • S-430 December 20220001104659-22-131415opens on sec.gov in a new tab

    At this first version the 86.2% fully diluted share those 60,000,000 shares are said to represent carries a single stated assumption on its face: that no ROCG public stockholder exercises its redemption rights. The $600.0 million equity value quoted for Tigo rests on $10.00 per ROCG share, which the filing identifies as the price at which ROCG completed its initial public offering in August 2021 rather than a current market price. Immediately before the effective time Tigo's preferred stock converts into common in accordance with its charter.

A stake with no amendment since is the filer’s last word on it, not proof it is still held — and percentages filed in different years are percentages of different floats, because this vehicle’s share count collapses at every redemption.

One line per filer, not per reporting person: a joint schedule names the management company, its funds and often the individual who controls them, and all of them report the same shares. Click a name for that filer’s whole footprint across every SPAC it has declared a stake in.

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 3674 (Semiconductors & Related Devices). The screen found it by filing SHAPE instead — S-1 2021-07-09 → 8-A12B 2021-08-04 → 424B4 2021-08-06 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts. SIC 3674 + self-described blank check in 424B4 0001104659-21-101571; 424B 0001104659-21-101571 priced 2021-08-06 under S-1 0001104659-21-090357 (file 333-257779, an offering for cash); common ticker ROCG off 10-Q 0001410578-22-003382 (2022-11-14); lifecycle EXITED. The pricing prospectus was filed under SEC file number 333-257779, which belongs to S-1 0001104659-21-090357 (2021-07-09) — 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 2021-08-06). Ending PROVEN, not inferred: CLOSED per 8-K 0001213900-23-044099 (2023-05-30) — 8-K item 5.06 "Change in Shell Company Status" (EDGAR item index, items: 1.01,2.01,3.03,5.01,5.02,5.03,5.05,5.06,7.01,9.01). EDGAR now files this CIK as "TIGO ENERGY, 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.

Deal — TIGO ENERGY, INC.
UNTAGGED

[CLOSED-RENAME] EDGAR CIK 0001855447 records "Roth CH Acquisition IV Co." ending 2023-05-30; the registrant continues as "TIGO ENERGY, INC.". The rename is the SEC's own record of what the vehicle became, keyed by CIK. Closed 2023-05-30. No deal value is set — a rename says what was acquired, never for how much. No date column is set: Deal has announcedAt, voteDate and expectedCloseAt and nowhere to record an actual close, so the SEC's date is kept here until that column exists.
