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 January 2021.
What it's doing now
It agreed to buy SeaStar Medical Holding Corp. 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

LMAO 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

LMF Acquisition Opportunities Inc was a blank-check company whose common stock traded on the Nasdaq Stock Market under the ticker LMAO. The company priced its initial public offering on January 27, 2021, under SEC file number 333-251962, following an S-1 registration filed on January 8, 2021. The SEC assigned the company CIK 0001831868 and SIC industry code 3841 for Surgical & Medical Instruments & Apparatus. The company completed a business combination and no longer files, with its closure established by Form 25 0001354457-22-000608 filed on October 28, 2022. EDGAR now files this CIK as SeaStar Medical Holding 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.

  • Revenue nearly doubled but remains under $0.7 million a quarter against a $3.8 million operating loss, and cash fell 42% over the half-year to $6.96 million.

  • The adult indication that the company describes as the larger market is gated on completing enrollment of 116 more patients and on a positive trial outcome, with a PMA filing no earlier than late 2027. Cash of $7.0 million stands against a $3.7 million quarterly loss.

  • A float of 3,997,002 shares after a January 2026 1-for-10 reverse split leaves the company with almost no equity base, so any financing is severely dilutive in percentage terms and the stock is structurally illiquid. Running the finance function through a part-time fractional CFO after terminating the incumbent, while losing two directors in the same year, points to a company operating on minimal infrastructure. The LMF trust was released at the de-SPAC.

  • The company links its going-concern status directly to shareholder approval of a reverse split - a rare and explicit admission that the listing and the business survive together. Approval came, and the 1-for-10 split executed January 5, 2026 cut the count from 35.9 million to 4.0 million shares. Holders kept the Nasdaq listing at the cost of an equity base so small that any subsequent raise is severely dilutive. No trust or floor remains from the LMF SPAC.

  • The two items pull in opposite directions on dilution. Removing the evergreen ends automatic annual additions to the plan, but the one-time increase from 570,457 to 2,070,457 shares is 1,500,000 new shares against 10,494,639 outstanding — roughly 14% — taken up front instead. The Lincoln Park proposal then authorizes open-ended sales into that facility at the agreed pricing terms. The company already effected a 1-for-25 reverse stock split on June 7, 2024, so today's share count is post-consolidation.

  • The vote is contractual rather than discretionary — the offering's terms obliged the company to convene it, and approval extends the January 2024 Series B Warrants to January 30, 2029, adding four years of overhang against only 6,570,789 shares outstanding. Placement Agent Warrants carry an exercise price of $2.125, representing 125% of the offering price per share and accompanying common warrant, and run to February 3, 2030, so the dilution stack extends well past the current decade's midpoint.

  • The notes convert at 125% of the Nasdaq closing price on the trading day before announcement or the applicable closing date — a premium conversion, which is unusual and favourable to existing holders compared with the discounted structures elsewhere in this backlog. The accompanying warrants carry a $14.00 exercise price, as do Additional Warrants for up to 15,832 shares issued under a letter agreement, so the equity only arrives if the stock recovers substantially from the level implied by 4,363,031 shares outstanding.

  • Tripling the equity plan to 9,778,457 shares and clearing 10,840,761 shares of Series A warrants plus the Series B tranche together represent a very large expansion against a base implied by the 25,137,306-share quorum threshold — roughly 75 million shares outstanding. Every one of those instruments predates the reverse split the company would carry out weeks later, so the eventual per-share economics depend on a ratio holders had not yet been asked to approve.

  • The vote arithmetic is now stated too: 2,587,500 shares, about 20% of the outstanding, are committed under the Letter Agreement and the Sponsor Support Agreement, leaving only 3,933,001 shares. Closing still requires Available Closing Acquiror Cash of at least $15,000,000 and $5,000,001 of net tangible assets after redemptions, against a PIPE of $7,000,000 — 700,000 Class A shares at $10.00 plus warrants over 700,000 shares at $11.50. Assuming no redemptions, SeaStar Medical's stockholders take about 35.9% of the combined company and the PIPE investors about 3.2%.

  • Closing needs $15,000,000 of Available Closing Acquiror Cash and a $5,000,001 net-tangible-asset floor, against a PIPE of only $7,000,000 — 700,000 Class A shares at $10.00 plus warrants over 700,000 shares at $11.50, subscribed August 23, 2022. The sponsor has already paid $1,035,000 into trust to move the deadline from July 29 to October 29, 2022, and it holds 2,587,500 founder shares bought for $25,000, about $0.012 each, which the filing values at roughly $26.5 million on the August 18, 2022 close, plus $5,738,000 of private placement warrants at about $1.00 each.

  • The Exchange Ratio is defined off $85,000,000, less SeaStar Medical's indebtedness and less its transaction expenses in excess of $800,000 — a cap that does not apply to transaction bonuses payable to executives or to the financial advisory fee payable to Maxim Group LLC. Immediately before the effective time SeaStar Medical's convertible notes convert into its common stock and its Series A-1, Series A-2 and Series B preferred then converts at the then-applicable rates, so the ratio is applied to a fully converted share count.

  • The capital structure is unwound in a fixed order before any exchange ratio applies: SeaStar Medical's convertible notes convert into common stock first, and only immediately after that, and immediately before the effective time, do the Series A-1, Series A-2 and Series B convertible preferred shares convert. Anyone modelling dilution has to apply those two steps before the merger consideration. The meeting is entirely unfixed — location, address, hour, meridiem and date are all bracketed placeholders — so no meeting date is recorded.

  • The capital structure unwinds in a fixed order before any consideration is measured: every SeaStar Medical convertible note converts into common stock first, then the preferred converts immediately after that and immediately before the effective time, so the share count depends on the sequence rather than on a single snapshot. The vote is at a special meeting held in lieu of the 2022 annual meeting, and its notice leaves location, address, time and date as bracketed placeholders. The combined company would trade on Nasdaq as ICU and ICUW.

  • What changed: Exhibit 99.1 to an 8-K of SeaStar Medical Holding Corporation (Nasdaq: ICU): the August 12, 2026 press release reporting Q2 2026 results.

R&D rose to $2.5 million from $1.0 million on clinical trial and personnel costs and G&A to $1.8 million from $1.0 million. Why it matters: The adult indication that the company describes as the larger market is gated on completing enrollment of 116 more patients and on a positive trial outcome, with a PMA filing no earlier than late 2027. Cash of $7.0 million stands against a $3.7 million quarterly loss.

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

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 3841 (Surgical & Medical Instruments & Apparatus). The screen found it by filing SHAPE instead — S-1 2021-01-08 → 8-A12B 2021-01-22 → 424B4 2021-01-27 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts.

The pricing prospectus was filed under SEC file number 333-251962, which belongs to S-1 0001564590-21-000649 (2021-01-08) — 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 2021-01-27). Ending PROVEN, not inferred: CLOSED per Form 25 0001354457-22-000608 (2022-10-28) — 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: LMF Acquisition Opportunities Inc. Unit). EDGAR now files this CIK as "SeaStar Medical Holding Corp" — 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.
