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 Amplitude Healthcare Holdings LLC, listed on Nasdaq in November 2019.
What it's doing now
It agreed to buy Jasper Therapeutics, Inc., a clinical-stage biopharmaceutical company 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

AMHC 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

Amplitude Healthcare Acquisition Corp was a blank-check company assigned SEC CIK 0001788028 and SIC industry code 2836 (Biological Products, (No Diagnostic Substances)) that priced its initial public offering on November 21, 2019, under SEC file number 333-234324. The company's common stock traded on the Nasdaq Stock Market under the ticker AMHC, which is printed on the cover page of 10-Q 0001213900-21-043115 filed on August 16, 2021. The IPO was priced according to 424B4 0001213900-19-024239, filed under S-1 0001213900-19-021144. The company completed a business combination and no longer files, with its closed status established by 8-K 0001213900-21-050592 filed on September 29, 2021, reporting a change in shell company status under item 5.06. EDGAR now files this CIK as Jasper Therapeutics, 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.

  • Cash fell by $21.4 million over six months while the reported loss shrank by $44 million — the loss improvement is mostly a warrant revaluation and a four-fifths cut in R&D spend, not cash generation. Equity of $1.4 million sits against $7.8 million of current liabilities.

  • The $132 million closed in July, after the June 30 balance-sheet date, so the $7.3 million cash figure and the runway-to-2028 statement describe two different moments. The preferred stock is non-voting and its conversion requires a shareholder vote that has not happened, so the dilution it represents is contingent on that approval.

  • The CVRs are not transferable except in limited circumstances, are not certificated, and will not be registered with the SEC or listed on any exchange, so a holder cannot sell the claim. If the milestone is met by the Expiration Date but no Monetization Event has occurred, the CVRs do not expire and the payment falls due 90 days after that event; on a Change of Control the payment comes at the earlier of consummation or 90 days after monetization.

  • Two structural features stand out for a former AMHC holder. A Parent Net Cash calculation means the exchange ratio flexes with how much cash Jasper actually has at closing, so continued burn between signing and closing directly reduces what existing holders keep. A Contingent Value Right means part of the consideration is deferred and conditional rather than paid in shares up front. The excerpt is the agreement's structure rather than its numbers, so the ratio and ownership split must be read from the merger consideration section itself.

  • The financing is the operative fact: roughly $132 million of new preferred plus $12 million of upfront licensing cash is stated to fund the combined company through the second half of 2028, which converts a cash-constrained de-SPAC into one with a multi-year runway. The cost is dilution — an all-stock acquisition plus non-voting convertible preferred means existing JSPR holders are diluted twice, once by Kira's shareholders and again on conversion of the preferred at whatever terms the purchase agreement sets.

  • Four amendments in, the registered amounts have not moved, so the structure stated at the outset holds: a separate 1,000,000-share non-voting class for certain Jasper stockholders, and 3,055,975 of the 27,500,000 voting shares reserved for Jasper options and restricted stock awards that AMHC assumes on consummation rather than issued as consideration. The prices rest on $9.91, the Nasdaq Capital Market high-low average for AMHC's Class A Common Stock on June 1, 2021, well before this amendment.

Show 4 more material filings
  • The two-class structure is the substance: 1,000,000 shares of non-voting common stock go to certain Jasper stockholders alongside the voting stock, so part of the target's position carries economics without a vote. Inside the 27,500,000 voting shares sit 3,055,975 that may become issuable under options and restricted stock awards AMHC assumes on consummation. The $9.91 is a market average used only to compute the fee, so the $282,435,000 aggregate is not a valuation of Jasper.

  • A non-voting class is created for the deal: 1,000,000 shares of New Jasper Non-Voting Common Stock go to certain Jasper stockholders alongside the voting stock, so part of the target's holding carries economics without a vote. Within the 27,500,000 voting shares sit 3,055,975 that may become issuable under options and restricted stock awards AMHC assumes on consummation, so the target's employee equity is counted inside the ceiling rather than added to it.

  • A separate non-voting class is created for part of the consideration: 1,000,000 of the 28,500,000 registered shares are New Jasper Non-Voting Common Stock, so some holders take the economics without a vote. Within the voting class, 3,055,975 shares are described as the maximum aggregate number that may become issuable rather than shares issued at closing, so the 27,500,000 is a ceiling containing a contingent tranche rather than a settled count of what changes hands.

  • A separate non-voting class is created for certain Jasper stockholders: 1,000,000 shares of New Jasper Non-Voting Common Stock, priced in the fee table on the same basis as the voting stock but carrying no vote. The voting line is not all new consideration either — 3,055,975 of the 27,500,000 shares are the maximum that may become issuable under Jasper options and restricted stock awards that AMHC assumes on consummation, so the target's equity-award overhang sits inside the registered ceiling rather than on top of it.


Filings

live EDGAR feed

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

  • What changed: Jasper Therapeutics, Inc. filed an 8-K on August 26, 2026, reporting that it received a notice from Nasdaq on August 21, 2026, stating the company no longer satisfies the minimum stockholders' equity requirement of $2,500,000 under Nasdaq Listing Rule 5550(b)(1), based on its Quarterly Report on Form 10-Q for the period ended June 30, 2026. The filing states the notice has no immediate effect on listing but requires the company to submit a compliance plan by October 5, 2026. The company anticipates regaining compliance through stockholder approval of the conversion of outstanding Non-Voting Convertible Preferred Stock at a special meeting. Why it matters: This filing signals a potential delisting risk for Jasper Therapeutics (JSPR) due to failing the $2.5 million stockholders' equity standard. While the SPAC AMHC is closed, this event impacts the post-merger entity's trading status and liquidity. The outcome depends on whether Nasdaq accepts the compliance plan and whether stockholders approve the preferred stock conversion; failure could lead to suspension or delisting, though the company expects to request a hearing if necessary.

  • What changed: The 10-Q filed under Commission file number 001-39138 is that of Jasper Therapeutics, Inc. (Nasdaq: JSPR, with ten warrants exercisable for one share at $115.00) for the quarter ended June 30, 2026. Cash and equivalents were $7,314 thousand against $28,692 thousand at December 31, 2025 and total assets $11,802 thousand against $35,779 thousand. Total liabilities fell to $10,389 thousand from $31,628 thousand, driven by the warrant liability dropping to $2,544 thousand from $16,164 thousand, and stockholders' equity was $1,413 thousand. Why it matters: Cash fell by $21.4 million over six months while the reported loss shrank by $44 million — the loss improvement is mostly a warrant revaluation and a four-fifths cut in R&D spend, not cash generation. Equity of $1.4 million sits against $7.8 million of current liabilities.

    Read from stored SEC filing text by a regex — no model is involved — and each side links to the filing it came from. “Not previously extracted” is a statement about our record, not about the company: the clause may be present in wording we do not match.

  • What changed: Jasper Therapeutics, Inc. issued a press release dated August 14, 2026 reporting second quarter 2026 results and a corporate update. It states that on July 16, 2026 Jasper completed the all-stock acquisition of Kira Pharmaceuticals and, concurrently, entered a securities purchase agreement for non-voting convertible preferred stock in a private placement co-led by Affinity Asset Advisors and Ikarian Capital that produced total gross proceeds of approximately $132 million. Why it matters: The $132 million closed in July, after the June 30 balance-sheet date, so the $7.3 million cash figure and the runway-to-2028 statement describe two different moments. The preferred stock is non-voting and its conversion requires a shareholder vote that has not happened, so the dilution it represents is contingent on that approval.

  • What changed: 8-K of Jasper Therapeutics, Inc. Item 5.07 (submission of matters to a vote): at the 2026 Annual Meeting on July 31, 2026, 21,121,396 shares, about 75% of the 28,009,802 voting common shares outstanding on the June 5, 2026 record date, were represented. Proposal 1 elected Class II directors Judith Shizuru (9,273,875 for, 419,763 withheld) and Tom Wiggans (9,280,610 for, 413,028 withheld), each with 11,427,758 broker non-votes. Proposal 2 ratified PricewaterhouseCoopers LLP 20,635,404 to 434,262. Proposal 3, advisory say-on-pay, passed 9,016,797 to 604,173. Why it matters: Routine annual-meeting results. The report says stockholders considered four proposals but the document gives voting results for three, so the fourth proposal's outcome is not stated in this filing. Broker non-votes of 11,427,758 exceed the votes cast for the directors, so the discretionary proposal drew far more shares than the contested ones.

  • What changed: 8-K of Jasper Therapeutics, Inc. Item 8.01 (other events): sets out the terms of the contingent value rights issued in the July 16, 2026 acquisition of Kira Pharmaceuticals under the merger agreement of the same date. Each holder of voting common stock of record immediately prior to the Effective Time receives one CVR per share. Each CVR entitles its holder to a pro rata portion of a $30.0 million Milestone Payment if the FDA issues a Priority Review Voucher in connection with briquilimab on or prior to December 31, 2028. The CVR record date was July 16, 2026, the closing date. Why it matters: The CVRs are not transferable except in limited circumstances, are not certificated, and will not be registered with the SEC or listed on any exchange, so a holder cannot sell the claim. If the milestone is met by the Expiration Date but no Monetization Event has occurred, the CVRs do not expire and the payment falls due 90 days after that event; on a Change of Control the payment comes at the earlier of consummation or 90 days after monetization.

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 2836 (Biological Products, (No Diagnostic Substances)). The screen found it by filing SHAPE instead — S-1 2019-10-25 → 8-A12B 2019-11-18 → 424B4 2019-11-21 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts.

The pricing prospectus was filed under SEC file number 333-234324, which belongs to S-1 0001213900-19-021144 (2019-10-25) — 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 2019-11-21). Ending PROVEN, not inferred: CLOSED per 8-K 0001213900-21-050592 (2021-09-29) — 8-K item 5.06 "Change in Shell Company Status" (EDGAR item index, items: 1.01,2.01,3.02,4.01,5.01,5.02,5.06,7.01,9.01). EDGAR now files this CIK as "Jasper Therapeutics, 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.
