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 RedOne Investment Limited, listed on Nasdaq in June 2021.
- What it's doing now
- It agreed in November 2022 to buy ProSomnus Holdings Inc., a Medical device company developing precision intraoral sleep apnea treatment devices company. The deal valued that business at about $113M. 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.

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.
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 fieldsLAAA 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.
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 filingsRead the full profile
Lakeshore Acquisition I Corp. was a blank-check company whose common stock traded on Nasdaq under the ticker LAAA. The company priced its IPO on June 14, 2021, as reflected in 424B prospectus 0001104659-21-080641, and its SEC CIK is 0001848000. Its lifecycle is closed: on December 6, 2022, Form 25 0001354457-22-000685 was filed under 17 CFR 240.12d2-2(a)(3), indicating that its Ordinary Share, Warrant, and Unit had come to evidence other securities in substitution therefor. The successor registrant, ProSomnus, Inc. (CIK 0001934064), filed an 8-K with item 2.01 (Completion of Acquisition) naming Lakeshore Acquisition I Corp., confirming that the vehicle completed a business combination and no longer files.
Material findings
from the full read of every filingEvery 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.
Closing Net Indebtedness as of October 31, 2022 was $14.9 million, so on that measure the deduction is already live and the consideration is below the headline. Lakeshore must make at least $40,000,000 available to ProSomnus immediately after closing, but the document states ProSomnus has the right to waive the Minimum Cash Condition, so there is no guarantee PubCo holds some or all of it. Shares equal to 3.0% of the Merger Consideration are escrowed for post-closing adjustments, and up to 3.0 million earn-out shares vest in three tranches at VWAP thresholds of $12.50, $15.00 and $17.50.

What changed: Definitive proxy statement/prospectus of Lakeshore Acquisition I Corp., dated November 14, 2022 and first mailed on or about that date, for an extraordinary general meeting on December 2, 2022 at 10 a.m. Eastern Time. The merger agreement dated May 9, 2022 effects the ProSomnus Holdings Inc. business combination in two steps: Lakeshore reincorporates into Delaware by merging into LAAA Merger Corp. (PubCo), then LAAA Merger Sub Inc. merges into ProSomnus. The Merger Consideration is $113,000,000 in PubCo stock, less the amount by which Closing Net Indebtedness exceeds $12,000,000. Why it matters: Closing Net Indebtedness as of October 31, 2022 was $14.9 million, so on that measure the deduction is already live and the consideration is below the headline. Lakeshore must make at least $40,000,000 available to ProSomnus immediately after closing, but the document states ProSomnus has the right to waive the Minimum Cash Condition, so there is no guarantee PubCo holds some or all of it.

RedOne Investment Limitednamed as sponsor in this SPAC’s filings — but with no researched track record behind it yet.
A missing score, not a score of zero — why
A Sponsor Score is only published once the sponsor’s prior vehicles have been verified on EDGAR and their post-close outcomes priced. That record does not exist for this sponsor yet, so no number and no tier is shown. That is a missing score, not a score of zero — and not a neutral 50 either.
Coverage so far: 301 of 1282 tracked SPACs (23%) are attached to a scored sponsor. This card fills in by itself as the research lands.

In plain English
tap a term to open itEvery 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.
