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 MedTech Acquisition Sponsor LLC, listed on Nasdaq in December 2020.
What it's doing now
It agreed to buy TriSalus Life Sciences, Inc., an oncology drug delivery technology and immunotherapeutics 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 TriSalus Life Sciences, Inc. does — read from trisaluslifesci.com on 26 August 2026

    TriSalus Life Sciences is developing a transformative platform to address barriers to the treatment of liver and pancreatic tumors, specifically focusing on overcoming intratumoral pressure and immunosuppressive environments. Their approach combines nelitolimod (SD-101), a selective toll-like receptor agonist, with their Pressure-Enabled Drug Delivery (PEDD) method to enable systemic immunotherapies like checkpoint inhibitors.

The score

deterministic, from filed fields

MTAC 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

MedTech Acquisition Corp was a blank-check company that priced its initial public offering on December 21, 2020, and listed its common stock on the Nasdaq Stock Market under the ticker MTAC. The registrant operated under SEC SIC industry code 3841 for Surgical & Medical Instruments & Apparatus. It completed a business combination and ceased filing as a blank-check vehicle, reporting a change in shell company status on August 16, 2023. EDGAR now files the entity under SEC CIK 0001826667 as TriSalus Life Sciences, 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.

  • ...

  • This is one of the few amendments in this corpus that states exactly what moved and what did not: the exchange ratio disclosure was supplemented and the expiration confirmed, and the terms of the offer were otherwise unchanged. The deadline is precise and unusual in its wording — one minute after 11:59 p.m. EDT on July 23, 2025 — and withdrawal rights lapse at the same instant, so a preferred holder who has tendered cannot pull back afterwards. The transaction converts preferred stock into common, retiring a class that ranks ahead of the common rather than raising new money.

  • The formula is the whole economics: preferred holders are paid out at a fixed $4.00 exchange price for a value that includes dividends they have not yet earned — everything that would accrue through August 10, 2027 — so the offer pulls forward more than two years of future dividends into shares issued today. Against 3,594,002 preferred shares outstanding, up to 11,860,206 common shares would be issued, roughly 3.3 common shares per preferred share.

  • If the consent passes, the Company gains the option to force every warrant left outstanding after the offer to convert at 0.27 shares, a ratio 10% below the 0.3 offered for tendering, so declining to tender is not a way to preserve the better terms. The offer and withdrawal rights expire one minute after 11:59 p.m. Eastern Standard Time on June 25, 2024, and completion is not conditioned on any minimum number of warrants being tendered. The public warrants trade on the Nasdaq Global Market as TLSIW; the private placement and working capital warrants are not listed anywhere.

  • Nothing a holder votes on changed, and the prospectus is not in this document — a reader looking here for the TriSalus terms must go to the amendment that carries it. What the exhibit index does record is how often the deal was reworked: the Agreement and Plan of Merger dated November 11, 2022 has a First Amendment dated April 4, 2023, a Second dated May 13, 2023 and a Third dated July 5, 2023. MedTech's amended and restated certificate of incorporation was itself amended on December 19, 2022 and again on June 15, 2023.

  • Nothing a stockholder votes on changed here. A reader looking to this accession for the terms of the TriSalus transaction will not find them and must read the amendment that carries the proxy statement/prospectus. What the index does show is that the merger agreement has been amended three times — April 4, 2023, May 13, 2023 and July 5, 2023 — and that the Foley & Lardner LLP legality opinion was filed with the immediately preceding amendment, which is the mechanical step that precedes a registration statement being declared effective.

  • The exchange ratio is an equity value of $220 million divided by TriSalus's shares outstanding immediately before the effective time, then divided by $10.00 — so every share TriSalus issues before closing reduces what each holder receives, and the denominator is being enlarged deliberately: ten series of preferred stock convert into common, convertible notes convert, and in-the-money warrants are automatically exercised. Out-of-the-money TriSalus warrants are cancelled for no consideration, and fractional shares are rounded down rather than paid in cash.

  • Ten separate series of TriSalus preferred stock — series A-1 through A-6 and series B, B-1, B-2 and B-3 — convert into common immediately before the effective time, along with any convertible notes, so the denominator of the exchange ratio is set by that whole capital structure rather than by the common stock alone. In-the-money TriSalus warrants are automatically exercised while out-of-the-money warrants are cancelled for no consideration. Fractional shares are rounded down rather than paid in cash, and MTAC intends to continue its Nasdaq listing as TLSI.

  • The meeting is held in lieu of the 2023 annual meeting and its date and time are blank, so no redemption deadline can be read from this version. Ten series of TriSalus preferred stock — A-1 through A-6 and B, B-1, B-2 and B-3 — plus any convertible notes convert into common immediately before the effective time, so the denominator of the ratio is the whole capital structure rather than the common stock alone. In-the-money warrants are automatically exercised and out-of-the-money warrants cancelled for no consideration, and fractional shares are rounded down rather than paid in cash.

  • The exchange ratio is anchored to a fixed equity value of $220 million divided by the target's share count, so what a TriSalus holder receives moves with that count rather than with any negotiated per-share price. The meeting is a special meeting in lieu of the 2023 annual meeting, conducted exclusively over the Internet by live video webcast, and both its date and its time are left blank in this version, so no redemption deadline can be read from it. The merger agreement was itself amended on April 4, 2023, shortly before this filing.

  • The denominator is assembled immediately before the closing from a long list: ten series of TriSalus preferred — A-1 through A-6 and B, B-1, B-2 and B-3 — convert into common at their then-applicable rates, convertible notes convert, and in-the-money warrants are automatically exercised into common. Out-of-the-money TriSalus warrants are cancelled for no consideration rather than rolled over. Fractional shares are rounded down to the nearest whole share, so each holder's entitlement is trimmed rather than paid out in cash.

  • The denominator is assembled immediately before the closing: ten series of TriSalus preferred — A-1 through A-6 and B, B-1, B-2 and B-3 — convert into common at their then-applicable rates, and any convertible notes convert under their own terms. Fractional shares are rounded down to the nearest whole share rather than paid out in cash. The meeting is held in lieu of the 2023 annual meeting, exclusively by live video webcast, on a date and at a time both left blank, so no redemption deadline can be read from this first version.

  • The surviving public issuer is Memic, not MTAC: each share of MTAC Class A and Class B stock converts into the right to receive one Memic ordinary share, MTAC warrants become Memic warrants, and shares held by MTAC, Merger Sub or Memic are cancelled without consideration. The $10.00 figure is engineered rather than assumed — it is the output of the reverse split ratio the agreement prescribes, not a trust value. Immediately after closing MTAC must contribute at least 50% of its total cash and liquid assets, net of redemptions and expenses.

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.

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 3841 (Surgical & Medical Instruments & Apparatus). The screen found it by filing SHAPE instead — S-1 2020-11-30 → 8-A12B 2020-12-16 → 424B4 2020-12-21 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts. SIC 3841 + self-described blank check in 424B4 0001104659-20-138083; 424B 0001104659-20-138083 priced 2020-12-21 under S-1 0001104659-20-130568 (file 333-251037, an offering for cash); common ticker MTAC off 10-K 0001104659-21-044719 (2021-03-31); lifecycle EXITED. The pricing prospectus was filed under SEC file number 333-251037, which belongs to S-1 0001104659-20-130568 (2020-11-30) — 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 2020-12-21). Ending PROVEN, not inferred: CLOSED per 8-K 0001104659-23-092586 (2023-08-16) — 8-K item 5.06 "Change in Shell Company Status" (EDGAR item index, items: 1.01,2.01,3.02,3.03,4.01,5.01,5.02,5.03,5.05,5.06,7.01,9.01). EDGAR now files this CIK as "TriSalus Life Sciences, 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.
