CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

Some of the statements contained in this prospectus supplement and the accompany prospectus, including the documents incorporated by reference herein and therein, constitute forward-looking statements within the meaning of the federal securities laws. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. These forward-looking statements include statements about our future financial and operating results; statements about our plans, strategies and objectives of management for our future operations; statements regarding future performance; and other statements. In some cases, you can identify these forward-looking statements by the use of terminology such as “anticipate,” “believe,” “can,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “forecast,” “intends,” “may,” “might,” “outlook,” “plan,” “possible,” “potential,” “predict,” “project,” “seek,” “should,” “strive,” “target,” “will,” “would” and the negative version of these words or other comparable words or phrases, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements may include, but are not limited to, statements about:

• the success, cost, timing and potential indications of our cellular therapy candidate development activities and clinical trials, as well as our ability to expand our biomaterials business and leverage our core expertise in cellular therapeutic development and manufacturing to generate revenues by providing contract manufacturing and development services to third parties;

• the timing of the initiation, enrollment and completion of planned clinical trials in the United States and foreign countries;

• our ability to obtain and maintain regulatory approval of our therapeutic candidates in any of the indications for which we plan to develop them, and any related restrictions, limitations, and/or warnings in the label of any approved therapeutic;

• our ability to obtain funding for our operations, including funding necessary to complete the clinical trials of any of our therapeutic candidates;

• our ability and plans to research, develop, manufacture and commercialize our therapeutic candidates, as well as our degenerative disease products;

• our ability to attract and retain collaborators with development, regulatory and commercialization expertise;

• the size of the markets for our therapeutic candidates and biomaterials products, and our ability to serve those markets;

• our ability to successfully commercialize our therapeutic candidates and biomaterials products;

• our ability to develop and maintain sales and marketing capabilities, whether alone or with potential future collaborators;

• our expenses, future revenues, capital requirements and needs for additional financing;

• our use of cash and other resources; and

• our expectations regarding our ability to obtain and maintain intellectual property protection for our therapeutic candidates, degenerative disease products, and our ability to operate our business without infringing on the intellectual property rights of others.

These forward-looking statements are based on information available as of the date of this prospectus supplement, accompany prospectus or such document incorporated by reference, and involve a number of risks and uncertainties. Accordingly, forward-looking statements should not be relied upon as representing our views as of any subsequent date, and we do not undertake any obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

S-iii

As a result of a number of known and unknown risks and uncertainties, our actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include:

• We have incurred net losses in every period since our inception, have no cellular therapeutic candidates approved for commercial sale and we anticipate that we will incur substantial net losses in the future. There is substantial doubt about our ability to continue as a going concern, which may affect our ability to obtain future financing and may require us to curtail our operations. We will need to raise additional capital to support our operations. This additional funding may not be available on acceptable terms or at all. Failure to obtain this necessary capital or address our liquidity needs may force us to delay, limit or terminate our operations, make further reductions in our workforce, discontinue our commercialization efforts for our biomaterials products as well as other clinical trial programs, liquidate all or a portion of our assets or pursue other strategic alternatives, and/or seek protection under the provisions of the U.S. Bankruptcy Code.

• We are currently required to make cash payments under our pre-paid advance agreement with YA II PN, Ltd., or Yorkville, and may not have sufficient cash available when due. If we fail to pay Yorkville when due, Yorkville could deem such non-payment an event of default under our pre-paid advance agreement and accelerate repayment of amounts advanced under the agreement, which would impact our liquidity, require us to modify our operations to meet any prepayment obligations and could force us to seek protection under the provisions of the U.S. Bankruptcy Code.

• Our placental-derived cellular therapy candidates represent a novel approach to cancer, infectious and degenerative disease treatments that creates significant challenges.

• Our business is highly dependent on the success of our lead therapeutic candidates. If we are unable to obtain regulatory approval for our lead candidates and effectively commercialize our lead therapeutic candidates for the treatment of patients in approved indications, our business would be significantly harmed.

• We rely on distribution arrangements for the sale of our biomaterials products. We may incur costs to meet demand forecasts that do not materialize or we may be unable to meet demand if our distribution partners do not provide adequate forecasts.

• Our commercial biomaterials business may be impacted if regulatory authorities determine that certain of our products that are, or are derived from, human cells or tissues do not qualify for reimbursement. For example, during 2022, the Center for Medicare & Medicaid Services, or CMS, began rejecting claims for Interfyl submitted by one of our distribution partners, which has not yet been resolved.

• We rely on CAR-T viral vectors from Sorrento Therapeutics, Inc., or Sorrento, for our CYCART-19 therapeutic candidate and termination of this license, or any future licenses, could result in the loss of significant rights, which would harm our business. In February 2023, Sorrento announced that it commenced voluntary proceedings under Chapter 11 of the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the Southern District of Texas. At this time, we cannot predict what impact the bankruptcy will have on Sorrento’s continued ability to perform under the license agreement.

• We rely and will continue to rely on third parties to conduct our clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to obtain regulatory approval of, or commercialize, our therapeutic candidates.

• The U.S. Food and Drug Administration, or FDA, regulatory approval process is lengthy and time-consuming, and we may experience significant delays in the clinical development and regulatory of our therapeutic candidates.

• We may not be able to file Investigational New Drug, or IND, applications to commence additional clinical trials on the timelines we expect, and even if we are able to, the FDA may not permit us to proceed without additional information or at all, and if so, we may encounter substantial delays in our

S-iv

clinical trials or may not be able to conduct our trials on the timelines we expect. For example, we submitted an IND for CYCART-19 in the first quarter of 2022 and FDA requested additional information before we could proceed with the clinical trial, and we continue to respond to FDA information requests before being able to proceed.

• We operate our own manufacturing and storage facility, which requires significant resources; manufacturing or other failures could adversely affect our clinical trials and the commercial viability of our therapeutic candidates and our biobanking and degenerative diseases businesses. We may not be successful in our plan to leverage our core expertise in cellular therapeutic development and manufacturing to generate revenues by providing contract manufacturing and development services to third parties.

• We rely on donors of healthy human full-term post-partum placentas to manufacture our therapeutic candidates and biomaterials products, and if we do not obtain an adequate supply of such placentas from qualified donors, development of our placental-derived allogeneic cells may be adversely impacted.

• Our clinical trials may fail to demonstrate the safety and/or efficacy of any of our therapeutic candidates, which would prevent or delay regulatory approval and commercialization.

• If our effort to protect the proprietary nature of the intellectual property related to our technologies are inadequate, we may not be able to compete effectively in our market.

• We are, and in the future may be, party to agreements with third parties. Disputes may arise with such third parties regarding the terms of such agreements, including terms governing payment obligations, contractual interpretation, or related intellectual property ownership or use rights, which could materially adversely impact us, including by requiring the payment of additional amounts, or requiring us to invest time and money in litigation or arbitration.

• Our therapeutic candidates may cause undesirable side effects or have other properties that could halt their clinical development, prevent their regulatory approval, limit their commercial potential or result in significant negative consequences.

• We face significant competition from other biotechnology and pharmaceutical companies, and our operating results will suffer if we fail to compete effectively.

• Our relationship with customers, physicians, and third-party payors are subject to numerous laws and regulations. If we or our employees, independent contractors, consultants, commercial partners and vendors violate these laws, we could face substantial penalties.

• Our business could be materially adversely affected by the effects of health pandemics or epidemics, including the ongoing COVID-19 pandemic and future outbreaks of the disease, in regions where we or third parties on which we rely have concentrations of clinical trial sites or other business operations.

• We will continue to incur significant costs as a result of operating as a public company, and our management will be required to devote substantial time to various compliance initiatives.

In addition, statements that “Celularity believes” or “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this prospectus supplement or accompanying prospectus or the documents incorporated by reference herein or therein, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and such statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. Except to the extent required by applicable law, we are under no obligation (and expressly disclaim

S-v

any such obligation) to update or revise their forward-looking statements whether as a result of new information, future events, or otherwise. For a further discussion of these and other factors that could cause our future results, performance or transactions to differ significantly from those expressed in any forward-looking statement, please see the section titled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission, or SEC, on March 31, 2023, or the 2022 Form 10-K, and in the other documents filed with the SEC and incorporated by reference herein. You should not place undue reliance on any forward-looking statements, which are based only on information currently available to us (or to third parties making the forward-looking statements).

PROSPECTUS SUPPLEMENT SUMMARY

The following summary is qualified in its entirety by, and should be read together with, the more detailed information and financial statements and related notes thereto incorporated by reference in this prospectus supplement and the accompanying prospectus. Before you decide to invest in our Class A common stock, you should carefully read the entire prospectus supplement and the accompanying prospectus, including the risk factors and the financial statements and related notes included or incorporated by reference herein and therein.

Unless the context indicates otherwise, references in this prospectus supplement to the “Company,” “Celularity,” “we,” “us,” “our” and similar terms refer to Celularity Inc., f/k/a GX Acquisition Corp., and its consolidated subsidiaries (including Celularity LLC). References to “GX” refer to the predecessor company prior to the consummation of the initial business combination.

Overview

We are a clinical-stage biotechnology company leading the next evolution in cellular medicine by developing off-the-shelf placental-derived allogeneic cell therapies for the treatment of cancer and immune and infectious diseases. We are developing a pipeline of off-the-shelf placental-derived allogeneic cell therapy product candidates including T cells engineered with a chimeric antigen receptor, or CAR, natural killer, or NK, cells, mesenchymal-like adherent stromal cells, or MLASCs, and exosomes. These therapeutic candidates target indications across cancer, infectious and degenerative diseases. We believe that by harnessing the placenta’s unique biology and ready availability, we will be able to develop therapeutic solutions that address a significant unmet global need for effective, accessible and affordable therapeutics. We also actively develop and market biomaterial products derived from the placenta. Prior to 2023, we marketed those products domestically primarily serving the orthopedic and wound care markets. We now intend to market placental biomaterials outside of the United States with an initial focus on markets in the Middle East and North Africa. Our biomaterials business today is comprised primarily of the sale of our Biovance and Interfyl products, directly or through our distribution network. Biovance is decellularized, dehydrated human amniotic membrane derived from the placenta of a healthy, full-term pregnancy. It is an intact, natural extracellular matrix that provides a foundation for the wound regeneration process and acts as a scaffold for restoration of functional tissue. Interfyl is human connective tissue matrix derived from the placenta of a healthy, full-term pregnancy. It is used by a variety of medical specialists to fill soft tissue deficits resulting from wounds, trauma, or surgery. We are developing new placental biomaterial products to deepen the commercial pipeline beyond Biovance and Interfyl. We also plan to leverage our core expertise in cellular therapeutic development and manufacturing to generate revenues by providing contract manufacturing and development services to third parties. The initial focus of this new service offering will be to assist development stage cell therapy companies with the development and manufacturing of their therapeutic candidates for clinical trials. In January 2023, we announced reprioritization of efforts which resulted in a reduction of approximately one-third of our workforce as of March 2023.

Our Celularity IMPACT platform capitalizes on the benefits of placenta-derived cells to target multiple diseases, and provides seamless integration, from bio sourcing through manufacturing cryopreserved and packaged allogeneic cells, in our purpose-built U.S.-based 147,215 square foot facility. We believe the use of placental-derived cells, sourced from the placentas of full-term healthy informed consent donors, has potential inherent advantages, from a scientific and an economic perspective. First, relative to adult-derived cells, placental-derived cells demonstrate greater stemness, meaning the ability to expand and persist. Second, placental-derived cells are immunologically naïve, meaning the cells have never been exposed to a specific antigen, and suggesting the potential for less toxicity and for low or no graft-versus-host disease, or GvHD, in transplant. Third, our placental-derived cells are allogeneic, meaning they are intended for use in any patient, as compared to autologous cells, which are derived from an individual patient for that patient’s sole use. We believe this is a key difference that will enable readily available off-the-shelf treatments that can be delivered faster, more reliably, at greater scale and to more patients.

S-1

On March 14, 2023, we received a notice from the Nasdaq notifying us that we no longer comply with the minimum bid price requirement for continued listing on the Nasdaq Capital Market because the closing bid price for our Class A common stock has fallen below $1.00 per share for the last 30 consecutive business days. We have a period of 180 calendar days, or until September 11, 2023, to regain compliance with the minimum bid price requirement. We intend to actively monitor the closing bid price of our Class A common stock and will evaluate available options to regain compliance with the minimum bid requirement. However, management can provide no assurance that we will be able to regain compliance with the minimum bid requirement during the 180-day compliance period, secure a second period of 180 days to regain compliance, or maintain compliance with the other Nasdaq listing requirements. In the event we are unable to regain or maintain compliance with the Nasdaq listing requirements, the liquidity of our publicly traded securities will be adversely affected and our ability to secure additional outside capital through public markets will be adversely affected.

Corporate Information

We were originally formed as a blank check company incorporated in Delaware in August 2018 for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses. In July 2021, we consummated our initial business combination with the entity now known as Celularity LLC through a two-step merger that ultimately resulted in Celularity LLC becoming our wholly-owned direct subsidiary. On the closing date, we changed our name from GX Acquisition Corp. to Celularity Inc. Our principal executive offices are located at 170 Park Avenue, Florham Park, New Jersey 07932, and our telephone number is (908) 768-2170. Our corporate website address is www.celularity.com. Information contained on or accessible through our website is not a part of this prospectus supplement, and the inclusion of our website address in this prospectus supplement is an inactive textual reference only.

RISK FACTORS

Investing in our Class A common stock involves a high degree of risk. Prior to making a decision about investing in our Class A common stock, you should carefully consider the specific risk factors discussed below, as well as in the sections entitled “Risk Factors” contained in the 2022 Form 10-K under the heading “Item 1A. Risk Factors” as well as in any applicable prospectus supplement and contained or to be contained in our filings with the SEC and incorporated by reference in this prospectus supplement and accompanying prospectus, together with all of the other information contained in this prospectus supplement and the accompanying prospectus. For a description of these reports and documents, and information about where you can find them, see “Where You Can Find More Information” and “Incorporation of Certain Information by Reference.” If any of the risks or uncertainties described in our SEC filings, any prospectus supplement or the accompanying prospectus or any additional risks and uncertainties actually occur, our business, financial condition and results of operations could be materially and adversely affected.

Additional Risks Related to This Offering and Our Class A Common Stock

We have incurred net losses in every period since our inception, have no cellular therapeutics approved for commercial sale and anticipate that we will incur substantial net losses in the future.

We are a clinical-stage biopharmaceutical company, have no cellular therapeutics approved for commercial sale, have not generated any revenue from cellular therapeutic sales to date, generate limited revenues from our degenerative disease and biobanking businesses, and will continue to incur significant research and development and other expenses related to our ongoing operations. Investment in biopharmaceutical product development is highly speculative because it entails substantial upfront capital expenditures and significant risk that any potential therapeutic candidate will fail to demonstrate adequate efficacy or an acceptable safety profile, gain regulatory approval and become commercially viable. As a result, we are not profitable and have incurred net losses in each period since our inception. We reported net income of $14.2 million and a net loss of $100.1 million for the years ended December 31, 2022 and 2021, respectively. We had an accumulated deficit of $645.5 million at December 31, 2022.

We expect to incur significant expenditures for the foreseeable future, and we expect these expenditures to increase as we continue our research and development of, and seeks regulatory approvals for, cellular therapeutic candidates based on our four placental-derived allogeneic cell types: CAR-T cells, unmodified NK cells, genetically modified NK cells, and MLASCs. Even if we succeed in commercializing one or more of our therapeutic candidates, we will continue to incur substantial research and development and other expenditures to develop and market additional therapeutic candidates. In addition, we expect to incur costs in relation to our anticipated biomaterials product ramp-up to support our expansion outside of the United States with an initial focus on markets in the Middle East and North Africa. We may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenue from our cellular therapeutic candidates. Our prior losses and expected future losses have had and will continue to have an adverse effect on our stockholders’ equity and working capital.

Our historical operating results indicate substantial doubt exists related to our ability to continue as a going concern.

We have incurred net losses and used significant cash in operating activities since inception, have no cellular therapeutic candidates approved for commercial sale and we anticipate that we will incur substantial net losses in the future. We have an accumulated deficit of $645.5 million and have cash and cash equivalents of $14.0 million as of December 31, 2022. Additionally, we are currently required to make monthly cash payments under our pre-paid advance agreement with Yorkville and do not have sufficient cash to meet such obligations. Unless our stock price improves or Yorkville waives the cash payment obligation, we could default under our obligation to Yorkville and it

S-5

could accelerate the maturity of our repayment obligations, which would impact our liquidity and require us to cease or severely modify our operations or seek protection under the U.S. Bankruptcy Code. Accordingly, there is substantial doubt about our ability to continue as a going concern, which may affect our ability to obtain future financing and may require us to further curtail our operations. For additional details, see the discussion under “Overview—Going Concern” in Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the 2022 Form 10-K. We will need to raise additional capital to support our operations. This additional funding may not be available on acceptable terms or at all. Failure to obtain this necessary capital or address our liquidity needs may force us to delay, limit or terminate our operations, make further reductions in our workforce, discontinue our commercialization efforts for our biomaterials products as well as other clinical trial programs, liquidate all or a portion of our assets or pursue other strategic alternatives, and/or seek protection under the provisions of the U.S. Bankruptcy Code.

We will need substantial additional financing to develop our therapeutics and implement our operating plans. If we fail to obtain additional financing, we may be unable to complete the development and commercialization of our therapeutic candidates.

We expect to spend a substantial amount of capital in the development and manufacture of our therapeutic candidates. We will need substantial additional financing to develop our therapeutics and implement our operating plans. In particular, we will require substantial additional financing to enable commercial production of our therapeutics and initiate and complete registration trials for multiple cellular therapeutics. Further, if approved, we will require significant additional amounts in order to launch and commercialize our therapeutic candidates.

As of December 31, 2022, we had $14.0 million in cash and cash equivalents. We will need to raise additional capital to implement our plans. Further, changing circumstances may cause us to consume capital significantly faster than we currently anticipate, and we may need to spend more money than currently expected because of circumstances beyond our control. We may also need to raise a large amount of capital sooner than currently anticipated if we choose to expand more rapidly than our present plans. In any event, we will require additional capital for the further development and commercialization of our therapeutic candidates, including funding our internal manufacturing capabilities and growth of our degenerative disease business.

We cannot be certain that additional funding will be available on acceptable terms, or at all. We have no committed source of additional capital and if we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the development or commercialization of our therapeutic candidates or other research and development initiatives. Our license agreements may also be terminated if we are unable to meet the payment obligations under the agreements, including our license from Sorrento. We could be required to seek collaborators for our therapeutic candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available or relinquish or license on unfavorable terms our rights to our therapeutic candidates in markets where we otherwise would seek to pursue development or commercialization ourself. Any of the above events could significantly harm our business, prospects, financial condition and results of operations and cause the price of our securities to decline.

Our stock price may be volatile or may decline regardless of our operating performance, and you may not be able to resell your shares at or above the price at which you purchase it.

The stock market generally, and our stock in particular, has experienced price and volume fluctuations. As a result of this volatility, you might not be able to sell your common stock at or above the price at which you purchase it. The market price for our common stock might continue to fluctuate significantly in response to various factors, some of which are beyond our control. These factors include:

• changes to the electric car industry, including demand and regulations;

• our ability to compete successfully against current and future competitors;

S-6

• competitive pricing pressures;

• our ability to obtain working capital financing;

• additions or departures of key personnel;

• sales of our common stock;

• our ability to execute our growth strategy;

• operating results that fall below expectations;

• loss of any strategic relationship;

• regulatory developments; and

• economic and other external factors.

In addition, the stock market in general has experienced significant price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of particular companies. These fluctuations might be even more pronounced in the new trading market for our stock. Additionally, securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. This litigation, if instituted against us, could result in substantial costs, divert our management’s attention and resources, and harm our business, operating results, and financial condition.

You will experience immediate and substantial dilution in the net tangible book value per share of the Class A common stock you purchase. You may also experience future dilution as a result of future equity offerings.

The price per share, together with the number of shares of our Class A common stock we propose to issue and ultimately will issue if this offering is completed, may result in an immediate decrease in the market price of our Class A common stock. Our historical net tangible book value as of December 31, 2022 was $(41.8) million, or approximately $(0.28) per share of our Class A common stock. After giving effect to the 9,230,770 shares of our Class A common stock to be sold in this offering at an offering price of $0.65 per share, our as adjusted net tangible book value as of December 31, 2022 would have been $(36.4) million, or approximately $(0.23) per share of our Class A common stock. This represents an immediate increase in the net tangible book value of $0.05 per share of our Class A common stock to our existing stockholders and an immediate dilution in net tangible book value of approximately $(0.88) per share of our Class A common stock to new investors, representing the difference between the offering price and our as adjusted net tangible book value as of December 31, 2022, after giving effect to this offering, and the offering price per share. Furthermore, if outstanding options or warrants are exercised, you could experience further dilution.

In addition, we have a significant number of stock options, RSUs and warrants outstanding, and, in order to raise additional capital, we may in the future offer additional shares of our Class A common stock or other securities convertible into or exchangeable for our Class A common stock at prices that may not be the same as the price per share in this offering. In the event that the outstanding options or warrants are exercised or settled, or that we make additional issuances of Class A common stock or other convertible or exchangeable securities, you could experience additional dilution. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders, including investors who purchase shares of Class A common stock in this offering. The price per share at which we sell additional shares of our Class A common stock or securities convertible into Class A common stock in future transactions, may be higher or lower than the price per share in this offering. As a result, purchasers of the shares we sell, as well as our existing stockholders, will experience significant dilution if we sell at prices significantly below the price at which they invested. See the section entitled “Dilution” below for a more detailed illustration of the dilution you would incur if you participate in this offering.

S-7

Resales of our Class A common stock in the public market during this offering by our stockholders may cause the market price of our Class A common stock to fall.

Sales of a substantial number of shares of our Class A common stock could occur at any time. The issuance of new shares of our Class A common stock could result in resales of Class A common stock by our current stockholders concerned about the potential ownership dilution of their holdings. In turn, these resales could have the effect of depressing the market price for our Class A common stock.

We will have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

We currently intend to use the net proceeds from the offering of securities under this prospectus supplement for working capital and general corporate purposes, as described in the section of this prospectus supplement entitled “Use of Proceeds.” We will have broad discretion in the application of the net proceeds in the category of general corporate purposes and investors will be relying on the judgment of our management regarding the application of the proceeds of this offering.

The precise amount and timing of the application of these proceeds, if any, will depend upon a number of factors, such as our funding requirements and the availability and costs of other funds. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. Depending on the outcome of our efforts and other unforeseen events, our plans and priorities may change and we may apply the net proceeds of this offering in different manners than we currently anticipate.

The failure by our management to apply these funds effectively could harm our business, financial condition and results of operations. Pending their use, we may invest the net proceeds from this offering in short-term, interest-bearing instruments. These investments may not yield a favorable return to our stockholders.

This offering may cause the trading price of our Class A common stock to decrease.

The price per share, together with the number of shares of Class A common stock we propose to issue and ultimately will issue if this offering is completed, may result in an immediate decrease in the market price of our Class A common stock. This decrease may continue after the completion of this offering.

There is no public market for the Warrants being offered in this offering.

There is no established public trading market for the Warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the Warrants on any securities exchange or nationally recognized trading system. Without an active market, the liquidity of the Warrants will be limited.

Holders of our Warrants will have no rights as common stockholders until they acquire our Class A common stock.

Until you acquire shares of our Class A common stock upon exercise of your Warrants, you will have no rights with respect to shares of our Class A common stock issuable upon exercise of your Warrants. Upon exercise of your Warrants, you will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

If we do not maintain a current and effective prospectus relating to the Class A common stock issuable upon exercise of the Warrants, holders will only be able to exercise such Warrants on a “cashless basis.”

If we do not maintain a current and effective prospectus relating to the shares of Common Stock issuable upon exercise of the Warrants at the time that holders wish to exercise such warrants, they will only be able to

S-8

exercise them on a “cashless basis,” and under no circumstances would we be required to make any cash payments or net cash settle such warrants to the holders. As a result, the number of shares of Class A common stock that holders will receive upon exercise of the Warrants will be fewer than it would have been had such holders exercised their Warrants for cash. Under the terms of the Warrants, we have agreed to use our best efforts to maintain a current and effective prospectus relating to the shares of Class A common stock issuable upon exercise of such warrants until the expiration of such warrants. However, we cannot assure you that we will be able to do so. If we are unable to do so, the potential “upside” of the holder’s investment in our company may be reduced.

The Warrants are speculative in nature.

The Warrants offered hereby do not confer any rights of Class A common stock ownership on their holders, such as voting rights or the right to receive dividends, but rather merely represent the right to acquire shares of Class A common stock at a fixed price. Specifically, commencing on the date of issuance, holders of the Warrants may acquire the Class A common stock issuable upon exercise of such warrants at an exercise price of $0.75 per share. Moreover, following this offering, the market value of the Warrants is uncertain, and there can be no assurance that the market value of the Warrants will equal or exceed the offering price.

The Warrants may not have any value.

The Warrants have an exercise price of $0.75 per share. The Warrants will be exercisable at any time on or after the six month anniversary of the date of issuance and will expire on the fifth anniversary of the date on which the Warrants become exercisable. In the event our Class A common stock price does not exceed the exercise price of the Warrants during the period when the Warrants are exercisable, the Warrants will expire worthless.

This offering is being conducted on a “best efforts” basis.

The Placement Agent is offering the shares on a “best efforts” basis, and the Placement Agent is under no obligation to purchase any shares for its own account. The Placement Agent is not required to sell any specific number or dollar amount of shares of Class A common stock in this offering but will use its best efforts to sell the securities offered in this prospectus supplement. As a “best efforts” offering, there can be no assurance that the offering contemplated hereby will ultimately be consummated.

Certain provisions of the Warrants could discourage an acquisition of us by a third party.

Certain provisions of the Warrants offered by this prospectus supplement could make it more difficult or expensive for a third party to acquire us. The Warrants prohibit us from engaging in certain transactions constituting “fundamental transactions” unless, among other things, the surviving entity assumes our obligations under the Warrants. Further, the Warrants provide that, in the event of certain transactions constituting “fundamental transactions,” with some exception, holders of such warrants will have the right, at their option, to require us to repurchase such Warrants at a price described in such Warrants. These and other provisions of the Warrants offered by this prospectus supplement could prevent or deter a third party from acquiring us even where the acquisition could be beneficial to you.

S-9

USE OF PROCEEDS

We intend to use the net proceeds from this offering, if any, for working capital and general corporate purposes, including in satisfaction of our obligations under our pre-paid advance agreement, or PPA, with Yorkville if we are required to make monthly cash payments under the PPA. We estimate that the net proceeds from this offering, after deducting the Placement Agent’s fees and estimated offering expenses payable by us, will be approximately $5.4 million.

We had approximately $37.0 million of borrowings outstanding under the PPA as of December 31, 2022, which are scheduled to mature in September 2023 absent Yorkville’s election to purchase shares of our Class A common stock pursuant to the PPA. On February 22, 2023, as a result of a triggering event in the PPA, we are currently required to make repayments of $6.0 million per month plus a payment premium of 5% of the principal amount being paid and all outstanding accrued and unpaid interest. The timing and amount of our actual expenditures will be based on many factors, including cash flows from operations and the anticipated growth of our business. As of the date of this prospectus supplement, we cannot specify with certainty all of the particular uses for the net proceeds to us from this offering. As a result, our management will have broad discretion regarding the timing and application of the net proceeds from this offering. Pending their ultimate use, we intend to invest the net proceeds in money market funds and short-term, investment-grade, interest-bearing instruments.

S-10

DILUTION

If you purchase shares of our Class A common stock in this offering, your interest will be diluted to the extent of the difference between the public offering price per share and the net tangible book value per share of our Class A common stock after this offering. We calculate net tangible book value per share by dividing our net tangible assets (tangible assets less total liabilities) by the number of shares of our Class A common stock issued and outstanding as of December 31, 2022.

Our historical net tangible book value at December 31, 2022 was approximately $(41.8) million or $(0.28) per share of our Class A common stock. After giving effect to the sale of our Class A common stock in the aggregate amount of approximately $5.4 million in this offering, at an offering price of $0.65 per share, and after deducting estimated offering expenses and discounts payable by us, our adjusted net tangible book value as of December 31, 2022 would have been approximately $(36.4) million, or $(0.23) per share of our Class A common stock. This represents an immediate increase in the net tangible book value of $0.05 per share of our Class A common stock to our existing stockholders and an immediate dilution in net tangible book value of $(0.88) per share of our Class A common stock to new investors. The following table illustrates per share dilution:

Public offering price per share				$	0.65
Net tangible book value per share as of December 31, 2022	$	(0.28	)
Increase in net tangible book value per share attributable to this offering		0.05
Adjusted net tangible book value per share as of December 31, 2022, after giving effect to this offering					(0.23	)
Dilution per share to new investors purchasing shares in this offering				$	(0.88	)

The information above is based on 148,921,187 shares of our Class A common stock outstanding as of December 31, 2022, and excludes:

• 9,381,841 shares of common stock and warrants to acquire an aggregate 10,131,841 shares of common stock issued subsequent to December 31, 2022 for $9.0 million;

• 26,109,409 shares of common stock issuable upon exercise of stock options outstanding as of December 31, 2022, at a weighted average exercise price of $4.82 per share;

• 2,274,029 shares of common stock issuable upon vesting of RSUs outstanding as of December 31, 2022;

• 15,115,658 shares of our Class A common stock available for future issuance as of December 31, 2022 under our equity compensation plans;

• 3,382,298 shares of our Class A common stock available for future issuance as of December 31, 2022 under our employee stock purchase plan; and

• 33,458,360 shares of Class A common stock issuable upon the exercise of outstanding warrants as of December 31, 2022, at a weighted average exercise price of $10.18 per share.

To the extent that outstanding options or warrants are exercised, or RSUs are settled, or we issue other shares, including under our at-the-market facility, investors purchasing shares in this offering could experience further dilution. In addition, to the extent that we raise additional capital through the sale of equity or convertible debt securities, the issuance of those securities could result in further dilution to our stockholders. We may also choose to request additional pre-paid advances or raise additional capital due to market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans.

Except as otherwise indicated, all information in this prospectus supplement assumes no exercise or forfeiture of the outstanding options or warrants after December 31, 2022, including, for the avoidance of doubt, any Warrants offered in this offering.

DESCRIPTION OF SECURITIES WE ARE OFFERING

We are offering (i) 9,230,770 shares of our Class A common stock and (ii) Warrants to purchase up to 9,230,770 shares of our Class A common stock. Each share of Class A common stock is being sold together with an accompanying Warrant. Each Warrant is exercisable for one share of our Class A common stock. The shares of Class A common stock and accompanying Warrants are immediately separable and will be issued separately. We are also offering the shares of our Class A common stock issuable from time to time upon exercise of the Warrants offered hereby.

Common Stock

The material terms and provisions of our Class A common stock and each other class of our securities that qualifies or limits our Class A common stock are described in the section entitled “Description of Capital Stock” beginning on page 9 of the accompanying prospectus.

We are authorized to issue 730,000,000 shares of Class A common stock, $0.0001 par value per share, and 10,000,000 shares of preferred stock, $0.0001 par value per share, all of which shares of preferred stock are undesignated.

Warrants

The following summary of certain terms and provisions of the Warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the Warrants, the form of which will be included as an exhibit to a Current Report on Form 8-K filed with the SEC in connection with this offering and incorporated by reference herein. Prospective investors should carefully review the terms and provisions of the form of Warrant for a complete description of the terms and conditions of the Warrants.

Duration and Exercise Price

Each Warrant offered will have an initial exercise price of $0.75 per share. The Warrants will be exercisable at any time on or after the six month anniversary of the date of issuance and will expire on the fifth anniversary of the date on which the Warrants become exercisable. The exercise price and number of shares of our Class A common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our Class A common stock and the exercise price. Warrants will be issued separately from our shares of Class A common stock and may be transferred separately immediately thereafter. For each share of Class A common stock purchased in this offering, one Warrant will be issued. Each Warrant is exercisable for one share of our Class A common stock.

Exercisability

The Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering a duly executed exercise notice accompanied by payment in full for the number of purchased upon such exercise (except in the case of a cashless exercise as discussed below). A holder (together with its affiliates) may not exercise any portion of the Warrant to the extent that the holder would own more than 4.99% (or, upon election by a holder prior to the issuance of any Warrants, 9.99%) of our outstanding Class A common stock immediately after exercise, except that upon at least 61 days’ prior notice from the holder to us, the holder may increase the amount of ownership of outstanding stock after exercising the holder’s Warrants up to 9.99% of the number of shares of our Class A common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the Warrants. No fractional shares of our Class A common stock will be issued in connection with the exercise of a Warrant. In lieu of fractional shares, we, at our election, will pay the holder an amount in cash equal to the fractional amount multiplied by the exercise price or round up to the next whole share.

S-12

Cashless Exercise

If, at the time a holder exercises its Warrants, a registration statement registering the issuance of the shares of our Class A common stock underlying the Warrants under the Securities Act is not then effective or available, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of our Class A common stock determined according to a formula set forth in the Warrants.

Fundamental Transaction

In the event of a fundamental transaction, as described in the Warrants and generally including any reorganization, recapitalization or reclassification of our Class A common stock, the sale, transfer or other disposition of all or substantially all of our properties or assets, our consolidation or merger with or into another person, the acquisition of more than 50% of our outstanding voting securities, the holders of the Warrants will be entitled to receive upon exercise of the Warrants the kind and amount of securities, cash or other property that the holders would have received had they exercised the Warrants immediately prior to such fundamental transaction. In addition, the holders of the Warrants have the right, under certain circumstances, to require us or a successor entity to redeem the Warrants for the cash paid in the fundamental transaction in the amount of the Black Scholes value of the unexercised portion of the Warrant on the date of the consummation of the fundamental transaction.

Transferability

Subject to applicable laws, a Warrant may be transferred at the option of the holder upon surrender of the Warrant together with the appropriate instruments of transfer.

Exchange Listing

We do not intend to list the Warrants on any securities exchange or nationally recognized trading system.

Right as a Stockholder

Except as otherwise provided in the Warrants or by virtue of such holder’s ownership of, the holders of the Warrants do not have the rights or privileges of holders of our Class A common stock, including any voting rights, until they exercise their Warrants.

The Placement Agent and its affiliates may hedge such exposure by entering into transactions that consist of either the purchase of credit default swaps or the creation of short positions in our securities or the securities of our affiliates, including potentially the Class A common stock offered hereby.

RISK FACTORS

Investing in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should carefully consider the risks and uncertainties described under the heading “Risk Factors” contained in the applicable prospectus supplement, and described under the section titled “Risk Factors” contained in our most recent annual report on Form 10-K and in our most recent quarterly report on Form 10-Q, as well as any subsequent filings with the SEC, which are incorporated by reference into this prospectus, together with other information in this prospectus and the documents incorporated by reference. The risks described in these documents are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial condition, results of operations or cash flow could be materially adversely affected. This could cause the trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also carefully read the section titled “Special Note Regarding Forward-Looking Statements.”

2

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, including the documents that we incorporate by reference, includes forward-looking statements within the meaning of the federal securities laws. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. These forward-looking statements include statements about our future financial and operating results; statements about our plans, strategies and objectives of management for future operations; statements regarding future performance; and other statements. In some cases, you can identify these forward-looking statements by the use of terminology such as “anticipate,” “believe,” “can,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “forecast,” “intends,” “may,” “might,” “outlook,” “plan,” “possible,” “potential,” “predict,” “project,” “seek,” “should,” “strive,” “target,” “will,” “would” and the negative version of these words or other comparable words or phrases, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements may include, but are not limited to, statements about:

• the success, cost, timing and potential indications of our cellular therapy candidate development activities and clinical trials;

• the timing of the initiation, enrollment and completion of planned clinical trials in the United States and foreign countries;

• our ability to obtain and maintain regulatory approval of our therapeutic candidates in any of the indications for which we plan to develop them, and any related restrictions, limitations, and/or warnings in the label of any approved therapeutic;

• our ability to obtain funding for our operations, including funding necessary to complete the clinical trials of any of our therapeutic candidates;

• our ability and plans to research, develop, manufacture and commercialize our therapeutic candidates, as well as our degenerative disease products;

• our ability to attract and retain collaborators with development, regulatory and commercialization expertise;

• the size of the markets for our therapeutic candidates, and our ability to serve those markets;

• our ability to successfully commercialize our therapeutic candidates;

• our ability to develop and maintain sales and marketing capabilities, whether alone or with potential future collaborators;

• our expenses, future revenues, capital requirements and needs for additional financing;

• our use of cash and other resources; and

• our expectations regarding our ability to obtain and maintain intellectual property protection for our therapeutic candidates, degenerative disease products, and our ability to operate our business without infringing on the intellectual property rights of others.

These forward-looking statements are based on information available as of the date of this prospectus, and current expectations, forecasts and assumptions, and involve a number of risks and uncertainties. Accordingly, forward-looking statements in this prospectus and in any document incorporated herein by reference should not be relied upon as representing our views as of any subsequent date, and we do not undertake any obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws. Our actual results or performance may be materially different from those expressed or implied by these forward-looking statements as a result of a number of known and unknown risks and uncertainties. Some factors that could cause actual results to differ include:

• risks inherent in developing cellular therapy candidates, such as substantial delays in clinical trials and ability to obtain regulatory approvals;

3

• risks associated with ongoing and planned clinical trials, such as unexpected data or clinical site activation rates or clinical trial enrollment rates that are lower than expected;

• our ability to obtain adequate financing to fund planned clinical trials and other expenses;

• competition and the ability to grow and manage growth profitably;

• changes in applicable laws or regulations;

• risks of undesirable side effects or other properties that could halt clinical development, prevent regulatory approval, limit commercial potential or result in significant negative consequences;

• difficulties arising from reliance on third-party licenses, or supply-chain or manufacturing challenges;

• risks from any strategic alliances or licensing arrangements entered into in the future and not being able to realize the benefits of such alliances or licensing arrangements;

• trends in the industry, changes in the competitive landscape, delays or disruptions due to the ongoing COVID-19 pandemic, as well as changes in the legal and regulatory framework for the industry or unexpected litigation or disputes and future expenditures; and

• risk of adverse effects of other economic, business and/or competitive factors, including geopolitical factors, such as the recent Russian invasion of Ukraine.

In addition, statements that “Celularity believes” or “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this prospectus, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and such statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. Except to the extent required by applicable law, we are under no obligation (and expressly disclaim any such obligation) to update or revise their forward-looking statements whether as a result of new information, future events, or otherwise. You should read this prospectus, any applicable prospectus supplement and any related free writing prospectus and the documents that we reference therein and have filed with the SEC as exhibits thereto completely and with the understanding that our actual future results may be materially different from any future results expressed or implied by these forward-looking statements. These estimates involve numerous assumptions, are subject to risks and uncertainties and are subject to change based on various factors, including those discussed under “Item 1A: Risk Factors” and elsewhere in our most recent Annual Report on Form 10-K, our subsequent Quarterly Reports on Form 10-Q and our Current Reports on Form 8-K, and the section of any accompanying prospectus supplement entitled “Risk Factors.”

OUR COMPANY

Overview

We are a clinical-stage biotechnology company leading the next evolution in cellular medicine by developing off-the-shelf placental-derived allogeneic cell therapies for the treatment of cancer and immune and infectious diseases. We are developing a pipeline of off-the-shelf placental-derived allogeneic cell therapy product candidates including T cells engineered with a chimeric antigen receptor, or CAR, unmodified and genetically modified natural killer, or NK cells, and mesenchymal-like adherent stromal cells, or ASCs. These therapeutic candidates target indications across cancer, infectious and degenerative diseases. We believe that by harnessing the placenta’s unique biology and ready availability, we will be able to develop therapeutic solutions that address a significant unmet global need for effective, accessible and affordable therapeutics. We currently have three active clinical trials and intend to work with the U.S. Food and Drug Administration, or FDA, to resolve its questions on an Investigational New Drug, or IND, application we submitted in the first quarter of 2022 before commencing an additional clinical trial.

Our Celularity IMPACT platform capitalizes on the benefits of placenta-derived cells to target multiple diseases, and provides seamless integration, from bio sourcing through manufacturing cryopreserved and packaged allogeneic cells, in our purpose-built U.S.-based 147,215 square foot facility. We believe the use of placental-derived cells, sourced from the placentas of full-term healthy informed consent donors, has potential inherent advantages, from a scientific and an economic perspective. First, relative to adult-derived cells, placental-derived cells demonstrate greater stemness, meaning the ability to expand and persist. Second, placental-derived cells are immunologically naïve, meaning the cells have never been exposed to a specific antigen, and suggesting the potential for less toxicity and for low or no graft-versus-host disease, or GvHD, in transplant. Third, our placental-derived cells are allogeneic, meaning they are intended for use in any patient, as compared to autologous cells, which are derived from an individual patient for that patient’s sole use. We believe this a key difference that will enable readily available off-the-shelf treatments that can be delivered faster, more reliably, at greater scale and to more patients. In addition, we also have non-core legacy operations that are complementary to our work in placenta-derived cell therapeutics, including our biobanking and degenerative disease operations, for which we commercialize biomaterial products directly and through our network of distribution partners.

Corporate Information

We were originally formed as a blank check company incorporated in Delaware in August 2018 for the purpose of effectuating a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or other similar business combination with one or more businesses. In July 2021, we consummated our initial business combination with the entity now known as Celularity LLC through a two-step merger that ultimately resulted in Celularity LLC becoming our wholly-owned direct subsidiary. On the closing date, we changed our name from GX Acquisition Corp. to Celularity Inc. Our principal executive offices are located at 170 Park Avenue, Florham Park, New Jersey 07932, and our telephone number is (908) 768-2170. Our corporate website address is www.celularity.com. Information contained on or accessible through our website is not a part of this prospectus, and the inclusion of our website address in this prospectus is an inactive textual reference only.

Implications of Being an Emerging Growth Company and a Smaller Reporting Company

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012, as amended, and therefore we intend to take advantage of certain exemptions from various public company reporting requirements, including not being required to have our internal control over financial reporting audited by our independent registered public accounting firm pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in this prospectus, our periodic reports and our proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and any golden parachute payments not previously approved. We will remain an

5

emerging growth company until the earliest of (i) the last day of the fiscal year in which the market value of our Class A common stock that is held by non-affiliates equals or exceeds $700 million as of the end of that year’s second fiscal quarter, (ii) the last day of the fiscal year in which we have total annual gross revenue of $1.07 billion or more during such fiscal year (as indexed for inflation), (iii) the date on which we have issued more than $1 billion in non-convertible debt in the prior three-year period or (iv) December 31, 2026.

We are also a “smaller reporting company” as defined in the Exchange Act. We may continue to be a smaller reporting company even after we are no longer an emerging growth company. We may take advantage of certain of the scaled disclosures available to smaller reporting companies and will be able to take advantage of these scaled disclosures for so long as the market value of the Class A common stock held by non-affiliates is less than $250.0 million measured on the last business day of our second fiscal quarter, or our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of the Class A common stock held by non-affiliates is less than $700.0 million measured on the last business day of our second fiscal quarter.

As a result, the information in this prospectus and that we provide to our investors in the future may be different than what you might receive from other public reporting companies.

USE OF PROCEEDS

Except as described in any applicable prospectus supplement, we intend to use the net proceeds from the sale of the securities under this prospectus for working capital and other general corporate purposes. General corporate purposes may include research and development and clinical development costs to support the development of our cellular therapy candidates and the expansion of our research and development programs, as well as costs associated with our commercial businesses; working capital; capital expenditures and other general corporate purposes. We may also use any net proceeds from this offering for acquisitions of complementary products, technologies or businesses, but we do not have any agreements or commitments for any specific acquisitions at this time. We have not determined the amount of net proceeds to be used specifically for such purposes. As a result, our management will retain broad discretion over the allocation of net proceeds. We will set forth in the applicable prospectus supplement our intended use for the net proceeds received from the sale of any securities. Pending the use of the net proceeds, we may temporarily invest the net proceeds in a variety of capital preservation instruments, including investment grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government, or may hold such proceeds as cash, until they are used for their stated purpose.

DESCRIPTION OF CAPITAL STOCK

The following is a summary of the rights and preferences of our capital stock. While we believe that the following description covers the material terms of our capital stock, the description may not contain all of the information that is important to you. We encourage you to read carefully this entire prospectus, any future related prospectus supplement and certificates of designation relating to the securities, as applicable, our amended and restated certificate of incorporation and amended and restated bylaws and the other documents we refer to for a more complete understanding of our capital stock. Copies of our certificate of incorporation and bylaws are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information” and “Information Incorporated by Reference.”

Authorized Capital

Our authorized share capital consists of 730,000,000 shares of Class A common stock, $0.0001 par value per share and 10,000,000 shares of preferred stock, $0.0001 par value, all of which shares of preferred stock are undesignated.

Class A Common Stock

Voting Rights

Except as otherwise required by law or as otherwise provided in any certificate of designation for any series of preferred stock, the holders of Class A common stock possess all voting power for the election of our directors and all other matters requiring stockholder action. Holders of Class A common stock are entitled to one vote per share on matters to be voted on by stockholders.

Dividends

Holders of Class A common stock will be entitled to receive such dividends, if any, as may be declared from time to time by our board of directors in its discretion out of funds legally available therefor. In no event will any stock dividends or stock splits or combinations of stock be declared or made on Class A common stock unless the shares of Class A common stock at the time outstanding are treated equally and identically.

Liquidation, Dissolution and Winding Up

In the event of our voluntary or involuntary liquidation, dissolution, distribution of assets or winding-up, the holders of the Class A common stock will be entitled to receive an equal amount per share of all of our assets of whatever kind available for distribution to stockholders, after the rights of the holders of the preferred stock have been satisfied.

Preemptive or Other Rights

Our stockholders have no preemptive or other subscription rights and there are no sinking fund or redemption provisions applicable to Class A common stock.

Election of Directors

Our board of directors is divided into three classes, Class I, Class II and Class III, with only one class of directors being elected in each year and each class serving a three-year term, except with respect to the election of directors at the special meeting held in connection with our initial business combination, Class I directors were elected to an initial one-year term (and three-year terms subsequently), the Class II directors were elected to an initial two-year term (and three-year terms subsequently) and the Class III directors were elected to an initial

9

three-year term (and three-year terms subsequently). There is no cumulative voting with respect to the election of directors, with the result that the holders of more than 50% of the shares voted for the election of directors can elect all of the directors.

Preferred Stock

Our certificate of incorporation provides that shares of preferred stock may be issued from time to time in one or more series. Our board of directors is authorized to fix the voting rights, if any, designations, powers and preferences, the relative, participating, optional or other special rights, and any qualifications, limitations and restrictions thereof, applicable to the shares of each series of preferred stock. The board of directors is able to, without stockholder approval, issue preferred stock with voting and other rights that could adversely affect the voting power and other rights of the holders of Class A common stock and could have anti-takeover effects. The ability of our board of directors to issue preferred stock without stockholder approval could have the effect of delaying, deferring or preventing a change of control or the removal of existing management. There are no shares of preferred stock outstanding.

Public Warrants

Our public warrants are issued under that certain warrant agreement dated May 20, 2019, by and between us and Continental Stock Transfer & Trust Company, as warrant agent. Pursuant to the warrant agreement, each whole public warrant entitles the registered holder to purchase one whole share of our Class A common stock at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing after August 15, 2021, which is the later of (a) 30 days after the consummation of our business combination or (b) 12 months from the effective date of the registration statement relating to our initial public offering. The public warrants will expire on July 15, 2026, which is five years after completion of our initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

We will not be obligated to deliver any shares of Class A common stock pursuant to the exercise of a public warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the shares of Class A common stock underlying the warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described below with respect to registration. No public warrant will be exercisable and we will not be obligated to issue shares of Class A common stock upon exercise of a public warrant unless Class A common stock issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the public warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a public warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will we be required to net cash settle any public warrant.

We filed a registration statement covering the shares of Class A common stock issuable upon exercise of the public warrants, and such registration statement was declared effective on August 12, 2021. As specified in the warrant agreement, we are obligated to maintain a current prospectus relating to those shares of Class A common stock until the warrants expire or are redeemed. During any period when we will have failed to maintain an effective registration statement, warrantholders may exercise public warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. If that exemption, or another exemption, is not available, holders will not be able to exercise their public warrants on a cashless basis.

Once the public warrants become exercisable, we may call the warrants for redemption:

• in whole and not in part;

• at a price of $0.01 per warrant;

• upon not less than 30 days’ prior written notice of redemption (the “30-day redemption period”) to each warrantholder; and

10

• if, and only if, the reported last sale price of Class A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending three business days before we send the notice of redemption to the warrantholders.

If and when the public warrants become redeemable by us, we may not exercise our redemption right if the issuance of shares of Class A common stock upon exercise of the public warrants is not exempt from registration or qualification under applicable state blue sky laws or we are unable to effect such registration or qualification.

We have established the last of the redemption criteria discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the public warrants, each warrantholder will be entitled to exercise its public warrants prior to the scheduled redemption date. However, the price of Class A common stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) as well as the $11.50 warrant exercise price after the redemption notice is issued.

If we call the public warrants for redemption as described above, our management will have the option to require any holder that wishes to exercise its warrant to do so on a “cashless basis.” In determining whether to require all holders to exercise their public warrants on a “cashless basis,” our management will consider, among other factors, our cash position, the number of public warrants that are outstanding and the dilutive effect on our stockholders of issuing the maximum number of shares of Class A common stock issuable upon the exercise of our public warrants. If our management takes advantage of this option, all holders of public warrants would pay the exercise price by surrendering their public warrants for that number of shares of Class A common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A common stock underlying the public warrants, multiplied by the difference between the exercise price of the public warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” shall mean the average last reported sale price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. If our management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of Class A common stock to be received upon exercise of the public warrants, including the “fair market value” in such case. Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption. We believe this feature is an attractive option to us if we do not need the cash from the exercise of the public warrants. If we call our warrants for redemption and our management does not take advantage of this option, our former sponsor, GX Sponsor LLC, and its permitted transferees would still be entitled to exercise their private placement warrants for cash or on a cashless basis using the same formula described above that other warrantholders would have been required to use had all warrantholders been required to exercise their warrants on a cashless basis, as described in more detail below.

A holder of a public warrants may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such public warrants, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the warrant agent’s actual knowledge, would beneficially own in excess of 4.9% or 9.8% (or such other amount as a holder may specify) of the shares of Class A common stock outstanding immediately after giving effect to such exercise.

If the number of outstanding shares of Class A common stock is increased by a stock dividend payable in shares of Class A common stock, or by a split-up of shares of Class A common stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Class A common stock issuable on exercise of each public warrant will be increased in proportion to such increase in the outstanding shares of Class A common stock. A rights offering to holders of Class A common stock entitling holders to purchase shares of Class A common stock at a price less than the fair market value will be deemed a stock dividend of a number of shares of Class A common stock equal to the product of (i) the number of shares of Class A common stock actually sold in such rights offering (or issuable under any other equity securities sold in

11

such rights offering that are convertible into or exercisable for Class A common stock) and (ii) one (1) minus the quotient of (x) the price per share of Class A common stock paid in such rights offering divided by (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for Class A common stock, in determining the price payable for Class A common stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) fair market value means the volume weighted-average price of Class A common stock as reported during the ten (10) trading day period ending on the trading day prior to the first date on which the shares of Class A common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if we, at any time while the public warrants are outstanding and unexpired, pay a dividend or make a distribution in cash, securities or other assets to the holders of Class A common stock on account of such shares of Class A common stock (or other shares of our capital stock into which the public warrants are convertible), other than in certain circumstances as described in the warrant agreement, then the warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each share of Class A common stock in respect of such event.

If the number of outstanding shares of our Class A common stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Class A common stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Class A common stock issuable on exercise of each public warrant will be decreased in proportion to such decrease in outstanding shares of Class A common stock.

Whenever the number of shares of Class A common stock purchasable upon the exercise of the public warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of shares of Class A common stock purchasable upon the exercise of the public warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of shares of Class A common stock so purchasable immediately thereafter.

In case of any reclassification or reorganization of the outstanding shares of Class A common stock (other than those described above or that solely affects the par value of such shares of Class A common stock), or in the case of any merger or consolidation of us with or into another corporation (other than a consolidation or merger in which we are the continuing corporation and that does not result in any reclassification or reorganization of our outstanding shares of Class A common stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety in connection with which we are dissolved, the holders of the public warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the public warrants and in lieu of the shares of our Class A common stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the public warrants would have received if such holder had exercised their public warrants immediately prior to such event. If less than 70% of the consideration receivable by the holders of Class A common stock in such a transaction is payable in the form of Class A common stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the public warrant properly exercises the public warrant within thirty days following public disclosure of such transaction, the warrant exercise price will be reduced as specified in the warrant agreement based on the Black-Scholes value (as defined in the warrant agreement) of the public warrant. The purpose of such exercise price reduction is to provide additional value to holders of the public warrants when an extraordinary transaction occurs during the exercise period of the public warrants pursuant to which the holders

12

of the public warrants otherwise do not receive the full potential value of the public warrants in order to determine and realize the option value component of the public warrant. This formula is to compensate the public warrant holder for the loss of the option value portion of the public warrant due to the requirement that the public warrant holder exercise the public warrant within 30 days of the event. The Black-Scholes model is an accepted pricing model for estimating fair market value where no quoted market price for an instrument is available.

The public warrants have been issued in registered form under the warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. You should review a copy of the warrant agreement, which is an exhibit to this registration statement, for a complete description of the terms and conditions applicable to the public warrants. The warrant agreement provides that the terms of the public warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 65% of the then outstanding public warrants to make any change that adversely affects the interests of the registered holders of public warrants.

The public warrants may be exercised upon surrender of the public warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified or official bank check payable to us, for the number of public warrants being exercised. The warrantholders do not have the rights or privileges of holders of Class A common stock and any voting rights until they exercise their public warrants and receive shares of Class A common stock. After the issuance of shares of Class A common stock upon exercise of the public warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

No fractional shares will be issued upon exercise of the public warrants. If, upon exercise of the public warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number the number of shares of Class A common stock to be issued to the warrantholder.

Anti-Takeover Provisions

Special Meetings of Stockholders

Our bylaws provide that special meetings of our stockholders may be called only by a majority vote of the board of directors, by the Chairperson of the board of directors, or by the chief executive officer.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

Our bylaws provide that stockholders seeking to bring business before our annual meeting of stockholders, or to nominate candidates for election as directors at our annual meeting of stockholders, must provide timely notice of their intent in writing. To be timely under our current bylaws and the bylaws, a stockholder’s notice will need to be received by the company secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the open of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting. Pursuant to Rule 14a-8 of the Exchange Act, proposals seeking inclusion in our annual proxy statement must comply with the notice periods contained therein. Our bylaws also specify certain requirements as to the form and content of a stockholders’ meeting. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders.

Authorized but Unissued Shares

Our authorized but unissued Class A common stock and preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, acquisitions and employee benefit plans. The existence of authorized but unissued and unreserved Class A common stock and preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

13

Exclusive Forum Selection

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 (subject to certain limited exceptions) shall be the sole and exclusive forum for any of the following claims (i) any derivative claim or cause of action brought on our behalf, (ii) any claim or cause of action asserting a claim of breach of a fiduciary duty owed by any of our director, officer or other employee or our stockholders, (iii) any claim or cause of action against us, our directors, officers or employees arising pursuant to any provision of the DGCL our certificate of incorporation or the bylaws, (iv) any claim or cause of action seeking to interpret, apply, enforce or determine the validity of the certificate of incorporation or the bylaws, (v) any claim or cause of action as to which the DGCL confers jurisdiction to the Court of Chancery of the State of Delaware; and (vi) any claim or cause of action against us or any of our current or former director, officer or other employee governed by the internal affairs doctrine, in all cases to the fullest extent permitted by law and subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. Any person or entity holding, owning or otherwise acquiring any interest in our shares of capital stock shall be deemed to have notice of and to have consented to such provisions.

Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law in the types of lawsuits to which they apply, a court may determine that these provisions are unenforceable, and to the extent they are enforceable, the provisions may have the effect of discouraging lawsuits against our directors and officers, although our stockholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. Additionally, we cannot be certain that a court will decide that these provisions are either applicable or enforceable, and if a court were to find the choice of forum provisions contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition.

Our certificate of incorporation provides that the exclusive forum provision will be applicable to the fullest extent permitted by applicable law. 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. Furthermore, Section 22 of the Securities Act of 1933, as amended, or 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. Accordingly, both state and federal courts have jurisdiction to entertain such claims. To prevent having to litigate claims in multiple jurisdictions and the threat of inconsistent or contrary rulings by different courts, among other considerations, the Proposed Charter provides that the federal district courts of the United States will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act.

We are subject to provisions of Section 203 of the DGCL regulating corporate takeovers under our certificate of incorporation. This statute prevents certain Delaware corporations, under certain circumstances, from engaging in a “business combination” with:

• a stockholder who owns 15% or more of our outstanding voting stock (otherwise known as an “interested stockholder”);

• an affiliate of an interested stockholder; or

• an associate of an interested stockholder, for three years following the date that the stockholder became an interested stockholder.

A “business combination” includes a merger or sale of more than 10% of our assets. However, the above provisions of Section 203 do not apply if:

• our board of directors approves the transaction that made the stockholder an “interested stockholder,” prior to the date of the transaction;

14

• after the completion of the transaction that resulted in the stockholder becoming an interested stockholder, that stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, other than statutorily excluded shares of common stock; or

on or subsequent to the date of the transaction, our initial business combination is approved by our board of directors and authorized at a meeting of our stockholders, and not by written consent, by an affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

Under certain circumstances, this provision will make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with us for a three-year period. This provision may encourage companies interested in acquiring us to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board of directors approves either the business combination or the transaction which results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

Limitation on Liability and Indemnification of Directors and Officers

Our certificate of incorporation eliminates directors’ liability for monetary damages to the fullest extent permitted by applicable law. Our certificate of incorporation requires us to indemnify and advance expenses to, to the fullest extent permitted by applicable law, our directors, officers and agents and prohibit any retroactive changes to the rights or protections or increase the liability of any director in effect at the time of the alleged occurrence of any act or omission to act giving rise to liability or indemnification. We believe these provisions in our certificate of incorporation are necessary to attract and retain qualified persons as directors and officers. However, these provisions may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

Transfer Agent and Registrar

The transfer agent for our Class A common stock and our public warrants is Continental Stock Transfer & Trust Company. The transfer agent’s address is One State Street Plaza, 30th Floor New York, New York 10004.

Listing

Shares of our Class A common stock have traded on the Nasdaq Global Select Market under the ticker symbol “CELU”. Our ticker symbol for our warrants exercisable for one share of Class A common stock at an exercise price of $11.50 per share is “CELUW”.

DESCRIPTION OF DEBT SECURITIES

This section describes the general terms and provisions of our debt securities that we may issue from time to time. We may issue debt securities, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any future debt securities we may offer under this prospectus, the applicable prospectus supplement will describe the specific terms of any debt securities offered through that prospectus supplement. The terms of any debt securities we offer under a prospectus supplement may differ from the terms we describe below. Unless the context requires otherwise, whenever we refer to the “indentures,” we are also referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue any senior debt securities under the senior indenture that we will enter into with the trustee named in the senior indenture. We will issue any subordinated debt securities under the subordinated indenture that we will enter into with the trustee named in the subordinated indenture. We have filed forms of these documents as exhibits to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The indentures will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We use the term “trustee” to refer to either the trustee under the senior indenture or the trustee under the subordinated indenture, as applicable.

The following summaries of material provisions of the senior debt securities, the subordinated debt securities and the indentures are subject to, and qualified in their entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplement related to the debt securities that we may offer under this prospectus, as well as the complete applicable indenture that contains the terms of the debt securities. Except as we may otherwise indicate, the terms of the senior indenture and the subordinated indenture are identical.

General

We will describe in the applicable prospectus supplement the terms of the series of debt securities being offered, including:

• the title;

• the principal amount being offered, and if a series, the total amount authorized and the total amount outstanding;

• any limit on the amount that may be issued;

• whether or not we will issue the series of debt securities in global form, and, if so, the terms and who the depository will be;

• the maturity date;

• whether and under what circumstances, if any, we will pay additional amounts on any debt securities held by a person who is not a United States person for tax purposes, and whether we can redeem the debt securities if we have to pay such additional amounts;

• the annual interest rate, which may be fixed or variable, or the method for determining the rate and the date interest will begin to accrue, the dates interest will be payable and the regular record dates for interest payment dates or the method for determining such dates;

• whether or not the debt securities will be secured or unsecured, and the terms of any secured debt;

16

• the terms of the subordination of any series of subordinated debt;

• the place where payments will be payable;

• restrictions on transfer, sale or other assignment, if any;

• our right, if any, to defer payment of interest and the maximum length of any such deferral period;

• the date, if any, after which, the conditions upon which, and the price at which, we may, at our option, redeem the series of debt securities pursuant to any optional or provisional redemption provisions and the terms of those redemption provisions;

• the date, if any, on which, and the price at which we are obligated, pursuant to any mandatory sinking fund or analogous fund provisions or otherwise, to redeem, or at the holder’s option, to purchase, the series of debt securities and the currency or currency unit in which the debt securities are payable;

• whether the indenture will restrict our ability or the ability of our subsidiaries, if any at such time, to:

• incur additional indebtedness;

• issue additional securities;

• create liens;

• pay dividends or make distributions in respect of our capital stock or the capital stock of our subsidiaries;

• redeem capital stock;

• place restrictions on our subsidiaries’ ability to pay dividends, make distributions or transfer assets;

• sell or otherwise dispose of assets;

• enter into sale-leaseback transactions;

• information describing any book-entry features;

• provisions for a sinking fund purchase or other analogous fund, if any;

• the applicability of the provisions in the indenture on discharge;

• whether the debt securities are to be offered at a price such that they will be deemed to be offered at an “original issue discount” as defined in paragraph (a) of Section 1273 of the Internal Revenue Code, as amended;

• the denominations in which we will issue the series of debt securities, if other than denominations of $1,000 and any integral multiple thereof;

• the currency of payment of debt securities if other than U.S. dollars and the manner of determining the equivalent amount in U.S. dollars; and

17

• any other specific terms, preferences, rights or limitations of, or restrictions on, the debt securities, including any additional events of default or covenants provided with respect to the debt securities, and any terms that may be required by us or advisable under applicable laws or regulations or advisable in connection with the marketing of the debt securities.

Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our Class A common stock, our preferred stock or other securities (including securities of a third party). We will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our Class A common stock, our preferred stock or other securities (including securities of a third-party) that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger or Sale

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indentures will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of all or substantially all of our assets. However, any successor to or acquirer of such assets must assume all of our obligations under the indentures or the debt securities, as appropriate. If the debt securities are convertible into or exchangeable for other securities of ours or securities of other entities, the person with whom we consolidate or merge or to whom we sell all of our property must make provisions for the conversion of the debt securities into securities that the holders of the debt securities would have received if they had converted the debt securities before the consolidation, merger or sale.

Events of Default Under the Indenture

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indentures with respect to any series of debt securities that we may issue:

• if we fail to pay interest when due and payable and our failure continues for 90 days and the time for payment has not been extended;

• if we fail to pay the principal, premium or sinking fund payment, if any, when due and payable at maturity, upon redemption or repurchase or otherwise, and the time for payment has not been extended;

• if we fail to observe or perform any other covenant contained in the debt securities or the indentures, other than a covenant specifically relating to another series of debt securities, and our failure continues for 90 days after we receive notice from the trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of the applicable series; and

• if specified events of bankruptcy, insolvency or reorganization occur.

We will describe in each applicable prospectus supplement any additional events of default relating to the relevant series of debt securities.

If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the trustee if notice is given by such holders, may declare the unpaid principal, premium, if any, and accrued interest, if any, due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the unpaid principal, premium, if any, and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the trustee or any holder.

18

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

Subject to the terms of the indentures, if an event of default under an indenture shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the trustee reasonable indemnity or security satisfactory to it against any loss, liability or expense. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series, provided that:

• the direction so given by the holder is not in conflict with any law or the applicable indenture; and

• subject to its duties under the Trust Indenture Act, the trustee need not take any action that might involve it in personal liability or might be unduly prejudicial to the holders not involved in the proceeding.

A holder of the debt securities of any series will have the right to institute a proceeding under the indentures or to appoint a receiver or trustee, or to seek other remedies if:

• the holder has given written notice to the trustee of a continuing event of default with respect to that series;

• the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have made written request, and such holders have offered reasonable indemnity to the trustee or security satisfactory to it against any loss, liability or expense or to be incurred in compliance with instituting the proceeding as trustee; and

• the trustee does not institute the proceeding, and does not receive from the holders of a majority in aggregate principal amount of the outstanding debt securities of that series other conflicting directions within 90 days after the notice, request and offer.

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities, or other defaults that may be specified in the applicable prospectus supplement.

We will periodically file statements with the trustee regarding our compliance with specified covenants in the indentures.

Modification of Indenture; Waiver

Subject to the terms of the indenture for any series of debt securities that we may issue, we and the trustee may change an indenture without the consent of any holders with respect to the following specific matters:

• to fix any ambiguity, defect or inconsistency in the indenture;

• to comply with the provisions described above under “—Consolidation, Merger or Sale”;

• to comply with any requirements of the SEC in connection with the qualification of any indenture under the Trust Indenture Act;

• to add to, delete from or revise the conditions, limitations, and restrictions on the authorized amount, terms, or purposes of issue, authentication and delivery of debt securities, as set forth in the indenture;

• to provide for the issuance of and establish the form and terms and conditions of the debt securities of any series as provided under “Description of Debt Securities—General,” to establish the form of any

19

certifications required to be furnished pursuant to the terms of the indenture or any series of debt securities, or to add to the rights of the holders of any series of debt securities;

• to evidence and provide for the acceptance of appointment hereunder by a successor trustee;

• to provide for uncertificated debt securities and to make all appropriate changes for such purpose;

• to add to our covenants such new covenants, restrictions, conditions or provisions for the benefit of the holders, to make the occurrence, or the occurrence and the continuance, of a default in any such additional covenants, restrictions, conditions or provisions an event of default or to surrender any right or power conferred to us in the indenture; or

• to change anything that does not materially adversely affect the interests of any holder of debt securities of any series.

In addition, under the indentures, the rights of holders of a series of debt securities may be changed by us and the trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, subject to the terms of the indenture for any series of debt securities that we may issue or as otherwise provided in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:

• extending the stated maturity of the series of debt securities;

• reducing the principal amount, reducing the rate of or extending the time of payment of interest, or reducing any premium payable upon the redemption or repurchase of any debt securities; or

• reducing the percentage of debt securities, the holders of which are required to consent to any amendment, supplement, modification or waiver.

Discharge

Each indenture provides that, subject to the terms of the indenture and any limitation otherwise provided in the prospectus supplement applicable to a particular series of debt securities, we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

• register the transfer or exchange of debt securities of the series;

• replace stolen, lost or mutilated debt securities of the series;

• maintain paying agencies;

• hold monies for payment in trust;

• recover excess money held by the trustee;

• compensate and indemnify the trustee; and

• appoint any successor trustee.

In order to exercise our rights to be discharged, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, any premium, and interest on, the debt securities of the series on the dates payments are due.

Form, Exchange and Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we otherwise specify in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indentures provide that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, The Depository Trust Company or another depository named by us and identified in a prospectus supplement with respect to that series.

20

At the option of the holder, subject to the terms of the indentures and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indentures and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will make no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series. If we elect to redeem the debt securities of any series, we will not be required to:

• issue, register the transfer of, or exchange any debt securities of that series during a period beginning at the opening of business 15 days before the day of mailing of a notice of redemption of any debt securities that may be selected for redemption and ending at the close of business on the day of the mailing; or

• register the transfer of or exchange any debt securities so selected for redemption, in whole or in part, except the unredeemed portion of any debt securities we are redeeming in part.

Information Concerning the Trustee

The trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs.

Subject to this provision, the trustee is under no obligation to exercise any of the powers given it by the indentures at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the trustee as our sole paying agent for payments any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

21

All money we pay to a paying agent or the trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

Governing Law

The indentures and the debt securities will be governed by and construed in accordance with the laws of the State of New York, except to the extent that the Trust Indenture Act is applicable.

Ranking of Debt Securities

The subordinated debt securities will be subordinate and junior in priority of payment to certain of our other indebtedness to the extent described in a prospectus supplement. The subordinated indenture does not limit the amount of subordinated debt securities that we may issue. It also does not limit us from issuing any other secured or unsecured debt.

The senior debt securities will rank equally in right of payment to all our other senior unsecured debt. The senior indenture does not limit the amount of senior debt securities that we may issue. It also does not limit us from issuing any other secured or unsecured debt.

22

DESCRIPTION OF WARRANTS

The following description, together with the additional information we may include in any applicable prospectus supplements, summarizes the material terms and provisions of the warrants that we may offer under this prospectus and the related warrant agreements and warrant certificates. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. If we indicate in the prospectus supplement, the terms of any warrants offered under that prospectus supplement may differ from the terms described below. Specific warrant agreements will contain additional important terms and provisions and will be incorporated by reference as an exhibit to the registration statement, which includes this prospectus.

General

We may issue warrants for the purchase of Class A common stock, preferred stock and/or debt securities in one or more series. We may issue warrants independently or together with Class A common stock, preferred stock and/or debt securities, and the warrants may be attached to or separate from these securities.

We plan to evidence each series of warrants by warrant certificates that we will issue under a separate warrant agreement. We will enter into the warrant agreement with a warrant agent. We will indicate the name and address of the warrant agent in the applicable prospectus supplement relating to a particular series of warrants.

We will describe in the applicable prospectus supplement the terms of the series of warrants, including:

DESCRIPTION OF UNITS

We may issue units comprised of shares of Class A common stock, shares of preferred stock, debt securities and warrants to purchase Class A common stock in any combination. We may issue units in such amounts and in as many distinct series as we wish. This section outlines certain provisions of the units that we may issue. If we issue units, they will be issued under one or more unit agreements to be entered into between us and a bank or other financial institution, as unit agent. The information described in this section may not be complete in all respects and is qualified entirely by reference to the unit agreement with respect to the units of any particular series. The specific terms of any series of units offered will be described in the applicable prospectus supplement. If so described in a particular supplement, the specific terms of any series of units may differ from the general description of terms presented below. We urge you to read any prospectus supplement related to any series of units we may offer, as well as the complete unit agreement and unit certificate that contain the terms of the units. If we issue units, forms of unit agreements and unit certificates relating to such units will be incorporated by reference as exhibits to the registration statement, which includes this prospectus.

Each unit that we may issue will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

The applicable prospectus supplement may describe:

• the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

• any provisions of the governing unit agreement;

• the price or prices at which such units will be issued;

• the applicable U.S. federal income tax considerations relating to the units;

• any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units; and

• any other terms of the units and of the securities comprising the units.

The provisions described in this section, as well as those described under “Description of Capital Stock,” “Description of Debt Securities” and “Description of Warrants” will apply to the securities included in each unit, to the extent relevant and as may be updated in any prospectus supplements. We may issue units in such amounts and in as many distinct series as we wish. This section summarizes terms of the units that apply generally to all series. Most of the financial and other specific terms of a particular series of units will be described in the applicable prospectus supplement.

Unit Agreements

We will issue the units under one or more unit agreements to be entered into between us and a bank or other financial institution, as unit agent. We may add, replace or terminate unit agents from time to time. We will identify the unit agreement under which each series of units will be issued and the unit agent under that agreement in the applicable prospectus supplement.

24

The following provisions will generally apply to all unit agreements unless otherwise stated in the applicable prospectus supplement:

Modification Without Consent

We and the applicable unit agent may amend any unit or unit agreement without the consent of any holder:

• to cure any ambiguity in any provisions of the governing unit agreement that differ from those described below;

• to correct or supplement any defective or inconsistent provision; or

• to make any other change that we believe is necessary or desirable and will not adversely affect the interests of the affected holders in any material respect.

We do not need any approval to make changes that affect only units to be issued after the changes take effect. We may also make changes that do not adversely affect a particular unit in any material respect, even if they adversely affect other units in a material respect. In those cases, we do not need to obtain the approval of the holder of the unaffected unit; we need only obtain any required approvals from the holders of the affected units.

Modification With Consent

We may not amend any particular unit or a unit agreement with respect to any particular unit unless we obtain the consent of the holder of that unit, if the amendment would:

• impair any right of the holder to exercise or enforce any right under a security included in the unit if the terms of that security require the consent of the holder to any changes that would impair the exercise or enforcement of that right; or

• reduce the percentage of outstanding units or any series or class the consent of whose holders is required to amend that series or class, or the applicable unit agreement with respect to that series or class, as described below.

Any other change to a particular unit agreement and the units issued under that agreement would require the following approval:

• if the change affects only the units of a particular series issued under that agreement, the change must be approved by the holders of a majority of the outstanding units of that series; or

• if the change affects the units of more than one series issued under that agreement, it must be approved by the holders of a majority of all outstanding units of all series affected by the change, with the units of all the affected series voting together as one class for this purpose.

These provisions regarding changes with majority approval also apply to changes affecting any securities issued under a unit agreement, as the governing document.

In each case, the required approval must be given by written consent.

Unit Agreements Will Not be Qualified Under Trust Indenture Act

No unit agreement will be qualified as an indenture, and no unit agent will be required to qualify as a trustee, under the Trust Indenture Act. Therefore, holders of units issued under unit agreements will not have the protections of the Trust Indenture Act with respect to their units.

Mergers and Similar Transactions Permitted; No Restrictive Covenants or Events of Default

The unit agreements will not restrict our ability to merge or consolidate with, or sell our assets to, another corporation or other entity or to engage in any other transactions. If at any time we merge or consolidate with, or

25

sell our assets substantially as an entirety to, another corporation or other entity, the successor entity will succeed to and assume our obligations under the unit agreements. We will then be relieved of any further obligation under these agreements.

The unit agreements will not include any restrictions on our ability to put liens on our assets, nor will they restrict our ability to sell our assets. The unit agreements also will not provide for any events of default or remedies upon the occurrence of any events of default.

Form, Exchange and Transfer

We will issue each unit in global (i.e., book-entry) form only. Units in book-entry form will be represented by a global security registered in the name of a depositary, which will be the holder of all the units represented by the global security. Those who own beneficial interests in a unit will do so through participants in the depositary’s system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depositary and its participants. We will describe book-entry securities, and other terms regarding the issuance and registration of the units in the applicable prospectus supplement.

Each unit and all securities comprising the unit will be issued in the same form.

If we issue any units in registered, non-global form, the following will apply to them:

• The units will be issued in the denominations stated in the applicable prospectus supplement. Holders may exchange their units for units of smaller denominations or combined into fewer units of larger denominations, as long as the total amount is not changed.

• Holders may exchange or transfer their units at the office of the unit agent. Holders may also replace lost, stolen, destroyed or mutilated units at that office. We may appoint another entity to perform these functions or perform them ourselves.

• Holders will not be required to pay a service charge to transfer or exchange their units, but they may be required to pay for any tax or other governmental charge associated with the transfer or exchange. The transfer or exchange, and any replacement, will be made only if our transfer agent is satisfied with the holder’s proof of legal ownership. The transfer agent may also require an indemnity before replacing any units.

• If we have the right to redeem, accelerate or settle any units before their maturity, and we exercise our right as to less than all those units or other securities, we may block the exchange or transfer of those units during the period beginning 15 days before the day we mail the notice of exercise and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers of or exchange any unit selected for early settlement, except that we will continue to permit transfers and exchanges of the unsettled portion of any unit being partially settled. We may also block the transfer or exchange of any unit in this manner if the unit includes securities that are or may be selected for early settlement.

Only the depositary will be entitled to transfer or exchange a unit in global form, since it will be the sole holder of the unit.

Payments and Notices

In making payments and giving notices with respect to our units, we will follow the procedures as described in the applicable prospectus supplement.

26

PLAN OF DISTRIBUTION

We may sell the securities from time to time pursuant to underwritten public offerings, “at the market offerings,” negotiated transactions, block trades or a combination of these methods. We may sell the securities to or through one or more underwriters or dealers (acting as principal or agent), through agents, or directly to one or more purchasers. We may distribute securities from time to time in one or more transactions:

• at a fixed price or prices, which may be changed;

• at market prices prevailing at the time of sale;

• at prices related to such prevailing market prices; or

• at negotiated prices.

A prospectus supplement or supplements will describe the terms of the offering of the securities, including, to the extent applicable:

• the name or names of the underwriters, dealers or agents, if any;

• the purchase price of the securities or other consideration therefor, and the proceeds, if any, we will receive from the sale;

• any over-allotment or other options under which underwriters may purchase additional securities from us;

• any agency fees or underwriting discounts and other items constituting agents’ or underwriters’ compensation;

• any public offering price;

• any discounts or concessions allowed or reallowed or paid to dealers; and

• any securities exchange or market on which the securities may be listed.

At-the-Market Offerings

If we reach an agreement with an underwriter on a placement, including the number of shares of stock to be offered in the placement and any minimum price below which sales may not be made, such underwriter would agree to use its commercially reasonable efforts, consistent with its normal trading and sales practices, to try to sell such shares on such terms. Underwriters could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an “at-the-market” offering as defined in Rule 415 promulgated under the Securities Act, sales made directly on the Nasdaq Stock Market, the existing trading market for our stock, or sales made to or through a market maker other than on an exchange. The name of any such underwriter or agent involved in the offer and sale of our stock, the amounts underwritten, and the nature of its obligations to take our stock will be described in the applicable prospectus supplement.

Underwriters and Agents

Only underwriters named in the prospectus supplement will be underwriters of the securities offered by the prospectus supplement. Dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and compensation received by them on resale of the securities may be deemed to be underwriting discounts. If such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act.

If underwriters are used in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions at a fixed public offering price or at varying prices

27

determined at the time of sale. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities offered by the prospectus supplement, other than securities covered by any over-allotment option. If a dealer is used in the sale of securities, we or an underwriter will sell the securities to the dealer, as principal. The dealer may then resell the securities to the public at varying prices to be determined by the dealer at the time of resale. To the extent required, we will set forth in the prospectus supplement the name of the dealer and the terms of the transaction. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may change from time to time.

We may use underwriters, dealers or agents with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, dealer or agent, the nature of any such relationship.

We may sell securities directly or through agents we designate from time to time. We may also designate agents to solicit offers to purchase the securities from time to time and may enter into arrangements for “at-the-market,” equity line or similar transactions. We will name any agent involved in the offering and sale of securities and we will describe any commissions payable to the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, the agent will act on a best-efforts basis for the period of its appointment.

We may provide agents, underwriters and dealers with indemnification against civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents, underwriters or dealers may make with respect to these liabilities. Agents, underwriters and dealers, or their affiliates, may engage in transactions with, or perform services for, us in the ordinary course of business.

All securities we may offer, other than Class A common stock, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any securities.

Any underwriter may engage in over-allotment, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price. Syndicate-covering or other short-covering transactions involve purchases of the securities, either through exercise of the over-allotment option or in the open market after the distribution is completed, to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a stabilizing or covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

Any underwriters that are qualified market makers on the Nasdaq Stock Market may engage in passive market making transactions in the Class A common stock on the Nasdaq Stock Market in accordance with Regulation M under the Exchange Act, during the business day prior to the pricing of the offering, before the commencement of offers or sales of the Class A common stock. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded. Passive market making may stabilize the market price of the securities at a level above that which might otherwise prevail in the open market and, if commenced, may be discontinued at any time.

28
