    ABOUT THE COMPANY
    This summary description about us and our business highlights selected information contained elsewhere in this prospectus or incorporated by reference into this prospectus. It does not contain all the information you should consider before investing in our securities. You should carefully read the entire prospectus, any applicable prospectus supplement and any related free writing prospectus, including the risks of investing in our common stock discussed under the heading “Risk Factors” contained in this prospectus, any applicable prospectus supplement and any related free writing prospectus, and under similar headings in the other documents that are incorporated by reference into this prospectus. You should also carefully read the information incorporated by reference into this prospectus, including our financial statements, and the exhibits to the registration statement of which this prospectus forms a part.
    The Company
    We are an innovative biotechnology company harnessing the power of adult stem cells to develop curative cell therapy products for cancer and autoimmune diseases that we believe will allow us to overcome the limitations of first-generation cell therapies. We have created a comprehensive, genetically engineered allogeneic cell therapy platform that includes:
    •
    Industry-leading induced pluripotent stem cells, or iPSCs, and differentiated know-how to generate immune effector cells from iPSCs, or iPSC- derived cells;
    ​
    •
    Clustered regularly interspaced short palindromic repeats, or CRISPR, mediated precision gene editing that allows us to incorporate multiple transgenes and remove target genes intended to optimize cell product performance;
    ​
    •
    Sophisticated protein engineering capabilities to develop proprietary next generation chimeric antigen receptors, or CARs;
    ​
    •
    Our proprietary Allo-Evasion™ technology intended to prevent rejection of our cell products by the host immune system; and
    ​
    •
    Cutting edge manufacturing capabilities intended to minimize product development risk and supply risk.
    ​
    We are leveraging our expertise in cellular reprogramming, genetic engineering, and manufacturing to develop therapies with the potential to overcome many of the challenges inherent to cell therapy and provide a significant advantage over existing cell therapy technologies. We believe that these vertically integrated capabilities will allow us to further expand our existing pipeline and develop therapeutics from iNK cells and iT cells that may provide enhanced clinical outcomes compared to available therapeutic options. We believe our commitment to developing off-the-shelf cell therapies will expand patient access and provide an unparalleled opportunity to advance the course of treatment. Our vision is to become a premier fully integrated biotechnology company by developing and ultimately commercializing off-the-shelf allogeneic cell therapies that dramatically and positively transform the lives of patients suffering from life-threatening cancers, as well as autoimmune diseases. To achieve our vision, we have assembled a world-class team whose members collectively have decades of experience in cell therapy and drug development, manufacturing, and commercialization.
    The field of cell therapy is rapidly evolving, with autologous and allogeneic technologies demonstrating the strong potential of this therapeutic modality. We believe that our industry leading, end-to-end iPSC-derived allogeneic cell therapy platform will allow us to overcome technical and biological limitations of other donor-derived cell therapies. The unlimited replication capacity of iPSCs allows us to incorporate multiple genetic modifications at precise sites, or loci, in the genome of iPSCs that are designed to improve cell function using a CRISPR-mediated approach targeting a DNA repair pathway called homology directed repair, or HDR. The precision of our CRISPR-HDR gene editing technology and clonal selection eliminates random integration events and allows more controlled expression of transgenes of interest compared to other gene editing methodologies. The self-renewal capacity of iPSCs also enables the generation of master cell banks derived from single genetically engineered clones thus allowing the implementation of cost-efficient manufacturing of drug product that can be made available on demand at any clinical site. We have assembled a unique and powerful combination
     
    4

    TABLE OF CONTENTS
     
    of technologies that bring together a preeminent iPSC-derived allogeneic cell therapy platform with highly advanced cell engineering and manufacturing capabilities. We believe this unique combination puts us in a position to change the oncology and autoimmune and inflammatory treatment paradigm and market.
    The Merger
    On April 11, 2024, we entered into the Merger Agreement, pursuant to which Merger Sub merged with and into Clade, with Clade continuing as the surviving corporation in the Merger and our wholly owned indirect subsidiary. Pursuant to the terms of the Merger Agreement, the aggregate upfront consideration was approximately $35 million, consisting of (i) approximately $15 million in cash and (ii) 4,535,333 shares of common stock. 793,687 shares of common stock, representing approximately 10% of the aggregate purchase price, were held back at the closing of the Merger as recourse to satisfy certain indemnification obligations of the Clade securityholders under the Merger Agreement and, subject to any forfeiture of Merger Shares as a result of indemnification claims made prior to the 18-month anniversary of the closing of the Merger, will be issued pursuant to the terms of the Merger Agreement following the 18-month anniversary of the closing of the Merger.
    Following the closing of the Merger, the Merger Agreement provides for one potential clinical development milestone payment of $10 million (which may be paid by us in cash, shares of its common stock or a combination thereof) to be made to Clade securityholders upon the achievement of the milestone.
    Pursuant to the Merger Agreement, we agreed to file a registration statement on Form S-3 to register for resale the Merger Shares no later than 90 days following the closing of the Merger. We agreed to use commercially reasonable efforts to have the registration statement declared effective as soon as practicable after the filing. This prospectus is part of that registration statement.
    Under the Merger Agreement, we also agreed to maintain the effectiveness of the registration statement until the earliest to occur of: (i) April 11, 2029, and (ii) the date that all Merger Shares covered by the registration statement are sold or are able to be sold by the holders thereof by relying on Rule 144 under the Securities Act without any restriction, including volume limitation.
    The description of the Merger Agreement is qualified in its entirety by reference to the Merger Agreement, which has been filed as an exhibit to our Current Report on Form 8-K filed on April 11, 2024. See “Where You Can Find More Information” and “Information Incorporated by Reference.” The representations, warranties and covenants made by us in the Merger Agreement were made solely for the benefit of the parties to such agreements, including, in some cases, for the purpose of allocating risk among the parties thereto, and should not be deemed to be a representation, warranty or covenant to you. Moreover, such representations, warranties or covenants were made as of an earlier date. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.
    Corporate Information
    Our primary executive offices are located at 25 North 38th Street, 11th Floor, Philadelphia, Pennsylvania 19104, and our telephone number is (267) 817-5790. Our corporate website is www.centurytx.com.

    Implications of Being an Emerging Growth Company and Smaller Reporting Company
    We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, or the Jobs Act. We will remain an emerging growth company until the earliest of (1) December 31, 2026, (2) the beginning of the first fiscal year after our annual gross revenue is $1.235 billion or more, (3) the date on which we have, during the previous three-year period, issued more than $1.0 billion in non-convertible debt securities and (4) as of the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeded $700 million as of the end of the second quarter of that fiscal year.
     
    5

    TABLE OF CONTENTS
     
    For as long as we remain an “emerging growth company,” we may take advantage of certain exemptions from various reporting requirements that are applicable to public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation and financial statements in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote to approve executive compensation and shareholder approval of any golden parachute payments not previously approved. We will take advantage of these reporting exemptions until we are no longer an “emerging growth company.”
    The JOBS Act provides that an “emerging growth company” can take advantage of an extended transition period for complying with new or revised accounting standards. We have irrevocably elected not to avail ourselves of this exemption and, therefore, we are subject to the same new or revised accounting standards as other public companies that are not “emerging growth companies.”
    We are also a “smaller reporting company,” as defined in Item 10(f)(1) of Regulation S-K. We will remain a smaller reporting company until the last day of the fiscal year in which (i) the market value of our common stock held by non-affiliates exceeds $250 million as of the end of that year’s second fiscal quarter, or (ii) our annual revenues exceeded $100 million during such completed fiscal year and the market value of our common stock held by non-affiliates exceeds $700 million as of the end of that year’s second fiscal quarter. If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

    PLAN OF DISTRIBUTION
    The selling stockholders, which as used herein includes donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from a selling stockholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.
    The selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:
    •
    ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;
    ​
    •
    block trades in which the broker-dealer will attempt to sell the shares as agent, but may position and resell a portion of the block as principal to facilitate the transaction;
    ​
    •
    purchases by a broker-dealer as principal and resale by the broker-dealer for its account;
    ​
    •
    an exchange distribution in accordance with the rules of the applicable exchange;
    ​
    •
    privately negotiated transactions;
    ​
    •
    short sales and settlement of short sales;
    ​
    •
    through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;
    ​
    •
    broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
    ​
    •
    a combination of any such methods of sale; and
    ​
    •
    any other method permitted by applicable law.
    ​
    The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act of 1933, as amended, or the Securities Act, amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of common stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.
    In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
    The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the purchase price of the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

    The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that rule.
    The selling stockholders and any underwriters, broker-dealers or agents that participate in the sale of the common stock or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act.

    TABLE OF CONTENTS​
     
    DESCRIPTION OF CAPITAL STOCK
    The following description of our capital stock is not complete and may not contain all the information you should consider before investing in our capital stock. This description is summarized from, and qualified in its entirety by reference to, our second amended and restated certificate of incorporation, which has been publicly filed with the SEC. See “Where You Can Find More Information.” For a complete description, you should refer to our second amended and restated certificate of incorporation, as amended from time to time, and second amended and restated bylaws, as amended from time to time, copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part.
    Common Stock
    Under our second amended and restated certificate of incorporation, or the Certificate of Incorporation, our authorized capital stock consists of 300,000,000 shares of common stock, par value $0.0001 per share, and 10,000,000 shares of preferred stock, par value $0.0001 per share. As of June 13, 2024, we had 84,500,780 shares of common stock outstanding.
    Voting.   Each holder of common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting shares are able to elect all of the directors. In addition, the affirmative vote of holders of two-thirds of the voting power of all of the then outstanding voting stock will be required to take certain actions, including amending certain provisions of our Certificate of Incorporation, such as the provisions relating to amending our second amended and restated bylaws, or the Bylaws, procedures for our stockholder meetings, the classified board, director liability, and exclusive forum for proceedings.
    Dividends.   Subject to preferences that may be applicable to any then outstanding preferred stock, holders of our common stock are entitled to receive dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.
    Liquidation and Dissolution.   In the event of our liquidation, dissolution or winding up, holders of our common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.
    Other Rights and Restrictions.   Holders of our common stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to our common stock. The rights, preferences and privileges of the holders of our common stock are subject to and may be adversely affected by the rights of the holders of shares of any series of our preferred stock that we may designated in the future.
    Listing.   Our common stock is listed on the Nasdaq Global Select Market under the symbol “IPSC.”
    Transfer Agent and Registrar.   The transfer agent and registrar for our common stock is Equiniti Trust Company, LLC.
    Preferred Stock
    The authorized shares of preferred stock are available for issuance without further action by our stockholders unless required by law or by the rules and regulations of any stock exchange on which our common stock may be listed. Our Certificate of Incorporation authorizes our board of directors to establish, from time to time, the number of shares to be included in each series of preferred stock, and to fix the designation, powers, privileges, preferences, and relative participating, optional or other rights, if any, of the shares of each series of preferred stock, and any of its qualifications, limitations or restrictions. Our board of directors is authorized to increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series of preferred stock then outstanding, without any further vote or action by the stockholders.
     
    16

    TABLE OF CONTENTS
     
    The issuance of preferred stock could adversely affect the voting power of holders of common stock and the likelihood that such holders will receive dividend payments and payments upon liquidation. In addition, the existence of unissued and unreserved common stock or preferred stock may enable our board of directors to issue shares to persons friendly to current management, which could render more difficult or discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise, and could thereby protect the continuity of our management and possibly deprive stockholders of opportunities to sell their shares of common stock at prices higher than prevailing market prices.
    As of June 13, 2024, we had no shares of preferred stock outstanding.
    Anti-Takeover Provisions of Delaware Law and Our Charter Documents
    Some provisions of Delaware law and our Certificate of Incorporation and our Bylaws contain provisions that could make the following transactions more difficult: acquisition of us by means of a tender offer; acquisition of us by means of a proxy contest or otherwise; or removal of our incumbent officers and directors. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in our best interests, including transactions that might result in a premium over the market price for our shares.
    These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.
    Section 203 of the Delaware General Corporation Law.   We are subject to Section 203 of the Delaware General Corporation Law, or the DGCL, which prohibits persons deemed “interested stockholders” from engaging in a “business combination” with a publicly-held Delaware corporation for three years following the date these persons become interested stockholders unless the business combination is, or the transaction in which the person became an interested stockholder was, approved in a prescribed manner or another prescribed exception applies. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation’s voting stock. Generally, a “business combination” includes a merger, asset, or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the board of directors, such as discouraging takeover attempts that might result in a premium over the market price of our common stock.
    Elimination of Stockholder Action by Written Consent.   Our Certificate of Incorporation provides that all stockholder actions must be effected at a duly called meeting of stockholders and not by consent in writing. A special meeting of stockholders may be called only by a majority of our board of directors, the chair of our board of directors, or our chief executive officer.
    Undesignated Preferred Stock.   The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of us. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of our company.
    Amendment of Charter Provisions.   Our Certificate of Incorporation provides that the affirmative vote of holders of at least 662∕3% of the voting power of all of the then outstanding shares of voting stock, voting as a single class, will be required to amend certain provisions of our Certificate of Incorporation, including provisions relating to the size of the board, removal of directors, special meetings, actions by written consent, and cumulative voting. The affirmative vote of holders of at least 662∕3% of the voting power of all of the then outstanding shares of voting stock, voting as a single class, will be required to amend or repeal our Bylaws unless such action is recommended by our board of directors at an annual or special meeting of stockholders, which would then require the affirmative vote of a majority

    TABLE OF CONTENTS
     
    of the voting power of all of the then outstanding shares of voting stock, voting as a single class. Additionally, our Bylaws may be amended by a simple majority vote of our board of directors.
    Classified Board; Election and Removal of Directors.   Our Certificate of Incorporation provides that our board of directors is divided into three classes, Class I, Class II, and Class III, with each class serving staggered terms, and will give our board of directors the exclusive right to expand the size of our board of directors and to elect directors to fill a vacancy created by the expansion of the board of directors or the resignation, death, or removal of a director.
    Choice of Forum.   Our Certificate of Incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, another state court located within the State of Delaware or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware) will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, stockholder, employee, or agent of ours to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, our Certificate of Incorporation or our Bylaws (in each case, as may be amended from time to time), (iv) any action asserting a claim governed by the internal affairs doctrine of the State of Delaware, or (v) any other action asserting an “internal corporate claim,” as defined in Section 115 of the DGCL, in all cases subject to the court having personal jurisdiction over all indispensable parties named as defendants.
    Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. In addition, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Securities Act or any other claim for which the federal and state courts have concurrent jurisdiction.
