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 CM Life Sciences, Inc. / EQRx, Inc. / SomaLogic, Inc. (Casdin Eli), listed on Nasdaq in September 2020.
What it's doing now
It agreed to buy GeneDx Holdings Corp., a rare disease genomic diagnostics 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

CMLF 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

CM Life Sciences, Inc. was a blank-check company whose common stock traded on the Nasdaq Stock Market under the ticker CMLF. The company priced its initial public offering on September 3, 2020, under SEC file number 333-246251, as detailed in a 424B prospectus. The registrant self-described as a blank check company in this prospectus, which was part of an S-1 registration for shares sold for cash. CM Life Sciences, Inc. was classified under SEC SIC industry code 8000 and filed a 10-Q on July 21, 2021. The company's lifecycle is closed following a business combination, a status established by an 8-K filed on July 28, 2021, reporting a change in shell company status.


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 a routine annual meeting for a company that came public via a SPAC, and every proposal passed. The one substantive data point is the say-on-pay vote: 1,471,593 against out of roughly 24.2 million votes cast on that proposal is about 6% opposition, which is modest but higher than the near-unanimous auditor ratification, and shareholders chose annual rather than triennial future votes. No financial results, transactions or capital changes are disclosed.

  • This is not a SPAC business combination and carries no redemption right. The document states plainly that the issuance proposals are put to stockholders only to comply with listing rule 5635 of the Nasdaq Stock Market, and that stockholders are not being asked to approve the acquisition or the private placement financing themselves. A reader who treats a tier-1 filing under a SPAC's CIK as that SPAC's own deal will mis-attribute this one: the vehicle had already completed its combination and is here acting as an operating company buying a target.

  • The consideration to OPKO is $150 million in cash at closing, subject to adjustment, plus 80 million shares of Class A common stock, plus up to $150 million more payable in cash or shares if revenue-based milestones are met for the fiscal years ending December 31, 2022 and December 31, 2023. No trust and no redemption right stands behind it: the cash is funded in part from a PIPE of 50 million shares of Class A common stock at $4.00 per share, $200 million gross before fees and expenses. Goldman Sachs's written opinion is dated January 14, 2022.

  • The consideration is an election with a hard cap and a fixed conversion price: a Sema4 stockholder electing cash takes a pro rata share of Closing Available Cash but never more than its total outstanding shares multiplied by the Per Share Amount, and whatever is not taken in cash converts into Company Class A common stock at that same Per Share Amount divided by $10.00. Sema4 Class B stock first converts into one one-hundredth of a share of Class A. The earnout includes Earnout RSUs, which vest and are not outstanding shares at the closing.

  • The stock leg is computed off a fixed $10.00 divisor rather than a market price: each Sema4 stockholder receives shares equal to its total shares times the Per Share Amount, less any cash it elects, divided by $10.00 — so electing cash reduces the share count at that fixed rate. On top sits an earnout capped in aggregate at 11% of the Earn-Out Total Outstanding Shares, released as 3.66%, 3.67% and 3.67% on three Triggering Events, each of which may occur only once. Sema4 Class B shares first convert into one one-hundredth of a Class A share each.

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: 8-K of GeneDx Holdings Corp. Item 2.02 (results of operations and financial condition): on August 3, 2026 the Company issued a press release and will hold a conference call announcing its financial results for the quarter ended June 30, 2026. The press release and an earnings presentation are furnished as Exhibits 99.1 and 99.2. The information furnished with Item 2.02, including both exhibits, shall not be deemed filed for Section 18 purposes nor incorporated by reference. Signed by CEO Katherine Stueland. Why it matters: Routine quarterly earnings furnishing; the report states no figure. Item 9.01 lists no cover-page Inline XBRL exhibit, unlike the other earnings 8-Ks filed the same week.

  • What changed: The successor to CM Life Sciences, Inc. filed its Q2 2026 10-Q reporting cash, cash equivalents and available-for-sale marketable securities of $132.5 million at June 30, 2026, which it says gives at least twelve months of liquidity. Class A shares outstanding rose to 29,803,164 from 29,245,296 at December 31, 2025 and total liabilities to $237.3 million from $215.5 million. Operating activities used $61.4 million of cash in the six months, driven by a net loss of $81.1 million. Contingent consideration of up to $10.5 million is payable if Fabric Genomics reaches $6.0 million of gross revenue. Why it matters: Routine quarterly reporting for a completed de-SPAC — no trust, redemption right or deadline remains. The number that matters is runway: $132.5 million on hand against $61.4 million of operating cash burn in six months is roughly a year of cover on the current rate, which is why management flags possible future sales of common or preferred equity or convertible debt. Any of those routes dilutes the 29.8 million shares outstanding, and the Fabric Genomics earnout adds up to $10.5 million payable in cash or stock on top.

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.

CMLF — company record
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 8000 (Services-Health Services). The screen found it by filing SHAPE instead — S-1 2020-08-14 → 8-A12B 2020-08-31 → 424B4 2020-09-03 — which nothing rewrites. Admission rule: src/lib/universe-admit.ts. SIC 8000 + self-described blank check in 424B4 0001213900-20-025225; 424B 0001213900-20-025225 priced 2020-09-03 under S-1 0001213900-20-022185 (file 333-246251, an offering for cash); common ticker CMLF off 10-Q 0001213900-21-037929 (2021-07-21); lifecycle EXITED. The pricing prospectus was filed under SEC file number 333-246251, which belongs to S-1 0001213900-20-022185 (2020-08-14) — 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 2020-09-03). Ending PROVEN, not inferred: CLOSED per 8-K 0001628280-21-014760 (2021-07-28) — 8-K item 5.06 "Change in Shell Company Status" (EDGAR item index, items: 1.01,2.01,3.02,4.01,5.01,5.02,5.03,5.06,9.01). 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.

NAME REPAIR2026-08-18

name "GeneDx Holdings Corp." -> "CM Life Sciences, Inc.". The stored name was the entity that SURVIVED the combination: EDGAR renames a registrant in place when the merger sub survives, so submissions.json answers with the survivor's name while the vehicle's own sits in formerNames, and a bulk ingest reads the former. The name written here is COMPANY CONFORMED NAME in the SEC header of this registrant's OWN pricing prospectus — 424B4 acc 0001213900-20-025225, filed 2020-09-03, the same date as this row's ipoDate — and it agrees with EDGAR's separate rename record. Nothing else on the row was touched.
