Sema4 Holdings Corp.

1,847,920 Shares of Class A Common Stock

This reoffer prospectus (“Reoffer Prospectus”) relates to the offer and sale from time to time by the selling stockholders named in this Reoffer Prospectus (the “Selling Stockholders”), or their permitted transferees, of up to 1,847,920 shares of Class A common stock, par value $0.0001 per share (“Class A Common Stock”), of Sema4 Holdings Corp., a Delaware corporation. This Reoffer Prospectus covers 1,847,920 shares of Class A Common Stock issuable to each Selling Stockholder upon the vesting of the Earn-Out RSUs that are expected to be granted by us to the Selling Stockholders pursuant to the earn-out provisions of the Merger Agreement (as defined below) and outside the Sema4 Holdings Corp. 2021 Equity Incentive Plan (the “Equity Incentive Plan”). We are not offering any shares of Class A Common Stock and will not receive any proceeds from the sale of the shares of Class A Common Stock by the Selling Stockholders pursuant to this Reoffer Prospectus. The Selling Stockholders are certain of our directors and executive and other officers, each of whom is an “affiliate” of our company (as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”)).

Subject to the satisfaction of any conditions to vesting of the shares of Class A Common Stock offered hereby pursuant to the terms of the relevant Earn-Out RSU agreements, and subject to the expiration of any lock-up agreements described herein, the Selling Stockholders may from time to time sell, transfer or otherwise dispose of any or all of the shares of Class A Common Stock covered by this Reoffer Prospectus through underwriters or dealers, directly to purchasers (or a single purchaser) or through broker-dealers or agents. If underwriters or dealers are used to sell the shares of Class A Common Stock, we will name them and describe their compensation in a prospectus supplement. The shares of Class A Common Stock may be sold in one or more transactions at fixed prices, prevailing market prices at the time of sale, prices related to the prevailing market prices, varying prices determined at the time of sale or negotiated prices. We do not know when or in what amount the Selling Stockholders may offer the shares of Class A Common Stock for sale. The Selling Stockholders may sell any, all or none of the shares of Class A Common Stock offered by this Reoffer Prospectus. See “Plan of Distribution” beginning on page 14 for more information about how the Selling Stockholders may sell or dispose of the shares of Class A Common Stock covered by this Reoffer Prospectus. The Selling Stockholders will bear all sales commissions and similar expenses. We will bear all expenses of registration incurred in connection with this offering, including any other expenses incurred by us in connection with the registration and offering that are not borne by the Selling Stockholders.

Shares of Class A Common Stock that will be issued pursuant to the Earn-Out RSUs that are expected to be granted to Selling Stockholders will be “control securities” under the Securities Act before their sale under this Reoffer Prospectus. This Reoffer Prospectus has been prepared for the purposes of registering the shares of Class A Common Stock under the Securities Act to allow for future sales by Selling Stockholders on a continuous or delayed basis to the public without restriction, provided that the amount of shares of Class A Common Stock to be offered or resold under this Reoffer Prospectus by each Selling Stockholder or other person with whom he or she is acting in concert for the purpose of selling shares of Class A Common Stock, may not exceed, during any three-month period, the amount specified in Rule 144(e) under the Securities Act.

On July 22, 2021, we consummated the transactions contemplated by that certain Agreement and Plan of Merger, dated as of February 9, 2021 (as amended, the “Merger Agreement”), by and among CM Life Sciences, Inc. (“CMLS” and, after the consummation of the Business Combination (as defined below), “Sema4 Holdings Corp.”), S-IV Sub, Inc. (“Merger Sub”) and Mount Sinai Genomics, Inc. d/b/a Sema4 (“Sema4”). In particular, on July 22, 2021, we consummated the merger contemplated by the Merger Agreement, whereby Merger Sub merged with and into Sema4, with Sema4 surviving the merger as a wholly-owned subsidiary of CMLS (the “Merger” and, together

with the other transactions contemplated by the Merger Agreement, the “Business Combination”). In connection with the consummation of the Business Combination, CMLS changed its name to “Sema4 Holdings Corp.” and Sema4 changed its name to “Sema4 OpCo, Inc.”

Our Class A Common Stock and public warrants are listed on the Nasdaq Global Select Market (the “Nasdaq”) under the symbols “SMFR” and “SMFRW”, respectively.

We are an “emerging growth company” under federal securities laws and are subject to reduced public company reporting requirements. Investing in our Class A Common Stock involves a high degree of risk. You should review carefully the risks and uncertainties described under the heading “Risk Factors” on page 12 of this Reoffer Prospectus and under similar headings in the documents that are incorporated by reference into this Reoffer Prospectus, as well as “Cautionary Note Regarding Forward-Looking Statements” on page 8 of this Reoffer Prospectus.

Neither the U.S. Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this Reoffer Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this Reoffer Prospectus is September 27, 2021.

Company Overview

We are a patient-centered, health intelligence company with a mission to use artificial intelligence, or AI, and machine learning to enable personalized medicine for all. Our integrated information platform leverages longitudinal patient data, AI-driven predictive modeling, and genomics in combination with other molecular and high-dimensional data in our efforts both to deliver better outcomes for patients and to transform the practice of medicine, including how disease is diagnosed, treated, and prevented.

We have established one of the largest, most comprehensive, and fastest growing integrated health information platforms, collecting and leveraging genomic and clinical data in partnership with patients, healthcare providers and an extensive ecosystem of life science industry contributors. We are now generating and processing over 35 petabytes of data per month, growing by almost 1.2 petabyte per month, and maintain a database that includes more than 11.7 million de-identified clinical records, many with genomic profiles, integrated in a way that enables physicians to proactively diagnose and manage disease. This expanding database is a virtuous cycle of data: new data enables us to further develop, train, and refine predictive models and drive differentiated insights, which models and insights we deploy through our next generation diagnostic and research solutions and portals to support clinicians and researchers and engage patients, all of which interactions generate more data to continue the cycle.

Today, by providing differentiated insights through diagnostic testing solutions to physicians and patients across the United States in areas such as reproductive health, or Women’s Health, population health, and oncology, or Oncology, we are reimbursed by payors, providers, and patients for providing these services. In collaboration with pharmaceutical and biotech, or Biopharma, companies, we receive payments for a broad range of services relating to the aggregated data on our information platform, such as consenting and recontacting patients, the development and implementation of a wide range of predictive models, including drug discovery programs, conducting real-world evidence studies, and aiding in the identification and recruitment of patients into clinical trials. Over the next several years, we expect to focus on expanding the revenue from our health system and Biopharma partners, while also working to continue to grow the volumes and revenues from our diagnostics test solutions.

While there are many companies seeking to harness the potential of “big data” to address the challenges within the healthcare ecosystem, we believe that few have the scale of our company combined with our revenue-generating diagnostics testing business and origins as a company conceived and nurtured within a world-class health system. These characteristics have enabled us to build a significant and highly differentiated technological and informational asset positioned to drive precision medicine solutions into the standard of care in an unparalleled way.

The mailing address of our principal executive office is located at 333 Ludlow Street, North Tower, 8th Floor Stamford, Connecticut 06902, and can be reached by telephone at (800) 298-6470.

Recent Developments

On July 22, 2021, we consummated the Business Combination. In particular, on July 22, 2021, we consummated the Merger, whereby Merger Sub merged with and into Sema4, with Sema4 surviving the Merger as a wholly-owned

subsidiary of CMLS. In connection with the consummation of the Business Combination, CMLS changed its name to “Sema4 Holdings Corp.” and Sema4 changed its name to “Sema4 OpCo, Inc.”

The Offering

This Reoffer Prospectus relates to the public offering by the Selling Stockholders listed in this Reoffer Prospectus of up to 1,847,920 shares of Class A Common Stock issuable to each Selling Stockholder pursuant to the Earn-Out RSUs that are expected to be granted by the Company to the Selling Stockholders pursuant to the earn-out provisions of the Merger Agreement and outside of the Equity Incentive Plan. Subject to the satisfaction of any conditions to vesting of the shares of Class A Common Stock offered hereby pursuant to the terms of the relevant Earn-Out RSU agreements, and subject to the expiration of any lock-up agreements described herein, the Selling Stockholders may from time to time sell, transfer or otherwise dispose of any or all of the shares of Class A Common Stock covered by this Reoffer Prospectus through underwriters or dealers, directly to purchasers (or a single purchaser) or through broker-dealers or agents. We will receive none of the proceeds from the sale of the shares of Class A Common Stock by the Selling Stockholders. The Selling Stockholders will bear all sales commissions and similar expenses in connection with this offering. We will bear all expenses of registration incurred in connection with this offering, as well as any other expenses incurred by us in connection with the registration and offering that are not borne by the Selling Stockholders.

RISK FACTORS

Investing in shares of our Class A Common Stock involves a high degree of risk. Investors should carefully consider the risks we have described as set forth under the caption “Risk Factors” in our Annual Report on Form 10-K/A for the fiscal year ended December 31, 2020, filed with the Commission on May 5, 2021, and our Current Report on Form 8-K filed with the Commission on July 28, 2021, as amended on August 16, 2021 (the “Super 8-K”), which are incorporated by reference herein, and subsequent reports filed with the Commission, together with the financial and other information contained or incorporated by reference in this prospectus. If any of the events or developments we have described occur, our business, financial condition, or results of operations could be materially or adversely affected. As a result, the market price of our Class A Common Stock could decline, and investors could lose all or part of their investment. The risks and uncertainties we have described are not the only risks and uncertainties that we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. The risks we have described also include forward-looking statements, and our actual results may differ substantially from those discussed in these forward-looking statements. See “Cautionary Note Regarding Forward-Looking Statements.”

DETERMINATION OF OFFERING PRICE

The Selling Stockholders will determine at what price they may sell the offered shares of Class A Common Stock, and such sales may be made at prevailing market prices or at privately negotiated prices. See “Plan of Distribution” below for more information.

We will not receive any proceeds from the sale of shares of our Class A Common Stock by the Selling Stockholders.

DESCRIPTION OF SECURITIES

The information set forth under the caption “Description of Securities” in the Super 8-K is incorporated herein by reference.

SELLING STOCKHOLDERS

The table below sets forth information concerning the resale of the shares by the Selling Stockholders. We will not receive any proceeds from the resale of the shares by the Selling Stockholders.

The table below sets forth, as of September 13, 2021 (the “Determination Date”), (i) the name of each person who is offering the resale of shares by this Reoffer Prospectus; (ii) the number of shares (and the percentage, if 1% or more) of Class A Common Stock beneficially owned (determined in the manner described in footnote (1) to the table below) by each person; (iii) the number of shares that each Selling Stockholder may offer for sale from time to time pursuant to this Reoffer Prospectus, whether or not such Selling Stockholder has a present intention to do so; and (iv) the number of shares (and the percentage, if 1% or more) of Class A Common Stock each person will own after the offering, assuming they sell all of the shares offered. Unless otherwise indicated, beneficial ownership is direct and the person indicated has sole voting and investment power. The address for each Selling Stockholder listed in the table below is c/o Sema4 Holdings Corp., 333 Ludlow Street, North Tower, 8th Floor Stamford, Connecticut 06902.

Pursuant to the earn-out provisions of the Merger Agreement, we may issue an aggregate of up to 19,021,576 shares of Class A Common Stock upon the occurrence of certain triggering events provided for in the Merger Agreement, which shares are comprised of an initial allocation of up to 16,331,812 shares of Class A Common Stock (the “Earn-Out Shares”) issuable to certain former stockholders of Sema4 and up to 2,689,764 shares of Class A Common Stock (the “Earn-Out RSU Shares”) issuable upon the vesting of certain RSU awards (“Earn-Out RSUs”) that are expected to be granted to certain former equity award holders of Sema4 and certain employees of our company. We expect to grant the Earn-Out RSUs on or after October 1, 2021. In the event any Earn-Out RSUs are forfeited following the Closing (for example, as a result of an Earn-Out RSU recipient no longer being an employee of our company), the Merger Agreement provides for a forfeiture pool in respect of the Earn-Out RSU Shares that were

originally allocated to such forfeited Earn-Out RSUs, with such Earn-Out RSU Shares becoming available for issuance to the other recipients of Earn-Out Shares and Earn-Out RSUs. In the case of each Selling Stockholder, the table below includes the Earn-Out RSU Shares underlying the Earn-Out RSU such Selling Stockholder is expected to be granted in respect of the initial allocation of Earn-Out RSU Shares (such Selling Stockholder’s “Allocated Earn-Out RSU Shares” and such Selling Stockholder’s “Allocated Earn-Out RSU”, respectively), as well as such Selling Stockholder’s pro rata portion of the reallocated Earn-Out RSU Shares underlying an Earn-Out RSU granted to such Selling Stockholder (such Selling Stockholder’s “Reallocated Earn-Out RSU Shares”), assuming that 100% of the Allocated Earn-Out RSUs (other than such Selling Stockholder’s Allocated Earn-Out RSU) are forfeited after the Closing.

The Selling Stockholders identified below may have sold, transferred or otherwise disposed of some or all of their shares since the date on which the information in the following table is presented in transactions exempt from or not subject to the registration requirements of the Securities Act. Information concerning the Selling Stockholders may change from time to time and, if necessary, we will amend or supplement this prospectus accordingly. We cannot give an estimate as to the number of shares of Class A Common Stock that will actually be held by the Selling Stockholders upon termination of this offering because the Selling Stockholders may offer some or all of their Class A Common Stock under the offering contemplated by this prospectus or acquire additional shares of Class A Common Stock. The total number of shares that may be sold hereunder will not exceed the number of shares offered hereby. Please read the section entitled “Plan of Distribution” in this Reoffer Prospectus.

Our amended and restated certificate of incorporation (the “Certificate of Incorporation”) contains provisions limiting the liability of directors, and our restated bylaws (the “Bylaws”) provide that we will indemnify each of our directors to the fullest extent permitted under Delaware law. The Certificate of Incorporation and Bylaws also provide the board of directors with discretion to indemnify officers and employees when determined appropriate by our board of directors.

We have entered into indemnification agreements with each of our directors and executive officers and certain other key employees.

PLAN OF DISTRIBUTION

The shares of Class A Common Stock covered by this Reoffer Prospectus are being registered by the Company for the account of the Selling Stockholders. The shares of Class A Common Stock offered may be sold from time to time directly by or on behalf of each Selling Stockholder in one or more transactions on the Nasdaq or any other stock exchange on which the Class A Common Stock may be listed at the time of sale, in privately negotiated transactions, or through a combination of such methods, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at fixed prices (which may be changed) or at negotiated prices. The Selling Stockholders may sell shares through one or more agents, brokers or dealers or directly to purchasers. Such brokers or dealers may receive compensation in the form of commissions, discounts or concessions from the Selling Stockholders and/or purchasers of the shares or both. Such compensation as to a particular broker or dealer may be in excess of customary commissions. The amount of shares of Class A Common Stock to be reoffered or resold under the Reoffer Prospectus by each Selling Stockholder and any other person with whom he or she is acting in concert for the purpose of selling shares of Class A Common Stock, may not exceed, during any three-month period, the amount specified in Rule 144(e) under the Securities Act.

In connection with their sales, a Selling Stockholder and any participating broker or dealer may be deemed to be “underwriters” within the meaning of the Securities Act, and any commissions they receive and the proceeds of any sale of shares may be deemed to be underwriting discounts and commissions under the Securities Act. We are bearing all costs relating to the registration of the shares of Class A Common Stock. Any commissions or other fees payable to brokers or dealers in connection with any sale of the shares will be borne by the Selling Stockholders or other party selling such shares. Sales of the shares must be made by the Selling Stockholders in compliance with all

applicable state and federal securities laws and regulations, including the Securities Act. In addition to any shares sold hereunder, Selling Stockholders may sell shares of Class A Common Stock in compliance with Rule 144. There is no assurance that the Selling Stockholders will sell all or a portion of the shares of Class A Common Stock offered hereby. The Selling Stockholders may agree to indemnify any broker, dealer or agent that participates in transactions involving sales of the shares against certain liabilities in connection with the offering of the shares arising under the Securities Act. We have notified the Selling Stockholders of the need to deliver a copy of this Reoffer Prospectus in connection with any sale of the shares of Class A Common Stock.

The anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares of Class A Common Stock and activities of the Selling Stockholders, which may limit the timing of purchases and sales of any of the shares of Common Stock by the Selling Stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of Class A Common Stock to engage in passive market-making activities with respect to the shares of Class A Common Stock. Passive market making involves transactions in which a market maker acts as both our underwriter and as a purchaser of shares of Class A Common Stock in the secondary market. All of the foregoing may affect the marketability of the shares of Class A Common Stock and the ability of any person or entity to engage in market-making activities with respect to the shares of Class A Common Stock.

Once sold under the registration statement of which this Reoffer Prospectus forms a part, the shares of Class A Common Stock will be freely tradable in the hands of persons other than our affiliates.

PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference.

The following documents filed by Sema4 Holdings Corp. (the “Registrant”) with the Commission pursuant to the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), are incorporated herein by reference:

(b)the Registrant’s Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2021 and June 30, 2021, filed with the Commission on May 24, 2021 and July 21, 2021, respectively;

All documents subsequently filed by the Registrant with the Commission pursuant to Sections 13(a), 13(c), 14, or 15(d) of the Exchange Act, prior to the filing of a post-effective amendment to the Registration Statement which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference into this Registration Statement and to be a part hereof from the date of the filing of such documents, except that information furnished to the Commission under Item 2.02 or Item 7.01 in Current Reports on Form 8-K and any exhibit relating to such information, shall not be deemed to be incorporated by reference in this Registration Statement.

Any statement contained herein or in a document incorporated or deemed to be incorporated by reference in this Registration Statement shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained in this Registration Statement, or in any other subsequently filed document which also is or is deemed to be incorporated by reference in this Registration Statement, modifies or supersedes such earlier statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Item 4. Description of Securities.

Not applicable.

Item 5. Interests of Named Experts and Counsel.

Not applicable.

Item 6. Indemnification of Directors and Officers.

Section 145 of the General Corporation Law of the State of Delaware (the “DGCL”), authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers under certain circumstances and subject to certain limitations. The terms of Section 145 of the DGCL are sufficiently broad to permit indemnification under certain circumstances for liabilities, including reimbursement of expenses incurred, arising under the Securities Act.

As permitted by the DGCL, the Amended and Restated Certificate of Incorporation of the Registrant contains provisions that eliminate the personal liability of its directors for monetary damages for any breach of fiduciary duties as a director, except liability for the following:

•any breach of a director’s duty of loyalty to the Registrant or the Registrant’s stockholders;

•acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;

•under Section 174 of the DGCL (regarding unlawful dividends and stock purchases); or

•any transaction from which the director derived an improper personal benefit.

As permitted by the DGCL, the Restated Bylaws of the Registrant provide that:

•the Registrant is required to indemnify its directors and executive officers to the fullest extent permitted by the DGCL, subject to very limited exceptions;

•the Registrant may indemnify its other employees and agents as set forth in the DGCL;

•the Registrant is required to advance expenses, as incurred, to its directors and executive officers in connection with a legal proceeding to the fullest extent permitted by the DGCL, subject to very limited exceptions; and

•the rights conferred in the Restated Bylaws of the Registrant are not exclusive.

The Registrant has entered into indemnification agreements with each of its directors and executive officers to provide these directors and executive officers additional contractual assurances regarding the scope of the indemnification set forth in the Amended and Restated Certificate of Incorporation and Restated Bylaws of the Registrant and to provide additional procedural protections. At present, there is no pending litigation or proceeding involving one of the Registrant’s directors or executive officers for which indemnification is sought. The indemnification provisions in the Amended and Restated Certificate of Incorporation, Restated Bylaws, and the indemnification agreements entered into between the Registrant and each of the Registrant’s directors and executive officers may be sufficiently broad to permit indemnification of the Registrant’s directors and executive officers for liabilities arising under the Securities Act. The Registrant carries liability insurance for the Registrant’s directors and officers. Certain of the Registrant’s directors are also indemnified by their employers with regard to service on the Registrant’s board of directors.

Item 9. Undertakings.

A.The undersigned Registrant hereby undertakes:

(1)To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

(i)To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement.

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed

with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement;

(iii)To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

provided, however, that clauses (1)(i) and (1)(ii) shall not apply if the information required to be included in a post-effective amendment by those clauses is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement;

(2)That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and

(3)To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering.

B.The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference into this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

C.Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the indemnification provisions summarized in Item 6, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES

Pursuant to the requirements of the Securities Act, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Stamford, State of Connecticut, on the 27th day of September, 2021.
