ABOUT THE PROSPECTUS SUPPLEMENT

This prospectus supplement is part of a registration statement that was filed with the Securities and Exchange Commission (the “SEC”) using a “shelf” registration process and consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and also supplements and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part is the accompanying prospectus, which provides more general information, some of which may not apply to this offering. This prospectus supplement may add, update or change information contained in the accompanying prospectus. Generally, when we refer to this prospectus, we are referring to both parts of this document combined. In addition, in this prospectus, as permitted by law, we “incorporate by reference” information from other documents that we file with the SEC.

We, the selling stockholder and the underwriter take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may provide you. Neither we, the selling stockholder nor the underwriter are making an offer to sell securities in any jurisdiction where the offer or sale is not permitted. You should assume the information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus is accurate only as of their respective dates.

We intend that the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 apply to these forward-looking statements. Forward-looking statements are not statements of historical fact but rather reflect our current expectations, estimates and predictions about future results and events. Words such as “may,” “will,” “could,” “should,” “anticipates,” “envisions,” “estimates,” “expects,” “projects,” “intends,” “plans,” “believes” and words or terms of similar substance used in connection with any discussion of future expectations as to industry and regulatory developments or business initiatives and strategies, future operating results or financial performance, and other future developments are intended to identify forward-looking statements. These include, among others, statements relating to:

Forward-looking statements involve risks and uncertainties. Factors that could cause actual results to differ materially from those contemplated by the forward-looking statements include, among others, the following:

S-3

Most of these factors are difficult to predict accurately and are generally beyond our control. You should consider the uncertainty and any risk related to forward-looking statements that we make. The above list of risks and uncertainties is only a summary of some of the most important factors and is not intended to be exhaustive. You should carefully review the risks and information contained, or incorporated by reference, in this prospectus supplement or the accompanying prospectus, including, without limitation, those risk factors discussed under the caption “Part I. Item 1A. Risk Factors,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 that was filed with the SEC on February 21, 2024 and in any reports subsequently filed with the SEC. New factors that are not currently known to us or of which we are currently unaware may also emerge from time to time that could materially and adversely affect us. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this prospectus supplement or the accompanying prospectus. Except as required by the federal securities laws, we undertake no obligation to update any forward-looking statement, release publicly any revisions to any forward-looking statements or report the occurrence of unanticipated events. For any forward-looking statements contained in any document, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

RISK FACTORS

Investing in our common stock involves risk. You should consider carefully the following risks and all of the information set forth or incorporated by reference in this prospectus supplement, including the risks and uncertainties described under the heading “Risk Factors” included in our Annual Report on Form 10-K for our most recent fiscal year and elsewhere in our public filings before investing in our common stock offered by this prospectus supplement.

Risks Relating to This Offering

Future sales of our common stock in the public market or the issuance of securities senior to our common stock could adversely affect the trading price of our common stock and our ability to raise funds in new stock offerings.

Sale of a substantial number of shares of our common stock in the public markets following this offering, or the perception that these sales might occur, could cause the market price of our common stock to decline or could impair our ability to raise capital through a future sale of, or pay for acquisitions using, our equity securities. In addition, the selling stockholder and certain other stockholders have certain registration rights that require us to register the sale of common stock held by them, including in connection with underwritten offerings.

We may issue common stock or equity securities senior to our common stock in the future for a number of reasons, including to finance our operations and business strategy, to adjust our ratio of debt-to-equity, as consideration in acquisitions or for other reasons. We cannot predict the effect, if any, that future sales or issuances of shares of our common stock or other equity securities, or the availability of shares of our common stock or any other equity securities for future sale or issuance, will have on the trading price of our common stock.

The price of our common stock may fluctuate significantly, which could negatively affect us and holders of our common stock.

The trading price of our common stock may fluctuate significantly in response to a number of factors, many of which are beyond our control. For instance, if our financial results are below the expectations of securities analysts and investors, the market price of our common stock could decrease, perhaps significantly. Other factors that may affect the market price of our common stock include announcements relating to significant corporate transactions; fluctuations in our quarterly and annual financial results; operating and stock price performance of companies that investors deem comparable to us; future sales by us or our subsidiaries of equity, equity-related or debt securities; the amount, if any, of dividends that we pay on our common stock; anticipated or pending investigations, proceedings or litigation that involve or affect us; changes in regional, national or global financial markets and economies and general market conditions, such as interest or foreign exchange rates, stock, commodity, credit or asset valuations or volatility; and changes in government regulation or proposals relating to us. In addition, the U.S. and global securities markets have experienced significant price and volume fluctuations. These fluctuations often have been unrelated to the operating performance of companies in these markets. Market fluctuations and broad market, economic and industry factors may negatively affect the price of our common stock, regardless of our operating performance. You may not be able to sell your shares of our common stock at or above the public offering price, or at all. Any volatility of or a significant decrease in the market price of our common stock could also negatively affect our ability to make acquisitions using our common stock.

S-15

USE OF PROCEEDS

We will not receive any proceeds from the sale of common stock by the selling stockholder in this offering. The selling stockholder will receive all of the proceeds from the sale of shares of our common stock in this offering.

S-16

SELLING STOCKHOLDER

The following table sets forth information as of July 25, 2024 with respect to the ownership of our common stock by the selling stockholder.

The amounts and percentages of shares beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Percentage computations are based on approximately 575,940,337 shares of our common stock outstanding as of July 25, 2024, before giving effect to the Repurchase and approximately 574,740,337 shares of our common stock outstanding after giving effect to the Repurchase, assuming we repurchase 1,200,000 shares.

Material Relationships with Selling Stockholder

The selling stockholder acquired the shares being sold under this prospectus supplement from us in connection with our acquisition of Adenza Holdings, Inc. Such shares of common stock were sold and issued by us to the selling stockholder pursuant to the terms and subject to the conditions of the Agreement and Plan of Merger, dated as of June 10, 2023, by and among us, Argus Merger Sub 1, Inc., Argus Merger Sub 2, LLC and Adenza Holdings, Inc. Additionally, in connection with the completion of the merger, we entered into (i) a stockholders’ agreement (as amended, the “Stockholders’ Agreement”) and (ii) a registration rights agreement (as amended, the “Registration Rights Agreement”), with the selling stockholder.

Pursuant to the Registration Rights Agreement, we granted the selling stockholder certain registration rights. Subject to some exceptions, including our right to defer a registration in certain circumstances, the selling stockholder has the right to require us to register the sale of the shares of common stock held by it on Form S-3, subject to offering size and other restrictions. The selling stockholder also has the right to request marketed and non-marketed underwritten offerings using a shelf registration statement. If we propose to file certain types of registration statements under the Securities Act with respect to an offering of shares of common stock, then we will be required to offer the selling stockholder the opportunity to register any number of shares of common stock that they request, on the terms and conditions set forth in the Registration Rights Agreement (customarily known as “piggyback rights”). The rights granted under the Registration Rights Agreement are subject to

S-17

customary restrictions including, if a registration is underwritten, limitation on the number of shares to be included in the underwritten offering if the underwriter advises us that the amount of securities to be underwritten is likely to have an adverse effect on the price, timing or the distribution of the securities to be offered. Expenses of registration under the Registration Rights Agreement, including the reasonable legal fees of counsel chosen by the selling stockholder, but excluding underwriter discounts and commissions and transfer taxes, will be paid by us. Any sales in the public market of any shares of common stock registrable granted under the Registration Rights Agreement could depress the market price of our shares of common stock. See “Risk Factors—Future sales of our common stock in the public market or the issuance of securities senior to our common stock could adversely affect the trading price of our common stock and our ability to raise funds in new stock offerings.” The Registration Rights Agreement also contains customary indemnification and contribution provisions. This offering is being made pursuant to the rights granted under the Registration Rights Agreement.

Pursuant to the Stockholders’ Agreement, the selling stockholder and Thoma Bravo, L.P. (collectively, the “seller parties”) have agreed to certain transfer restrictions with respect the shares of common stock owned by it, including a lock-up with respect to the transfer of the remaining shares of common stock not being sold in this offering, with such shares released from the lock-up on May 1, 2025 (subject to certain exceptions). The Stockholders’ Agreement further provides that the seller parties will be entitled to propose for nomination one director for election to our board of directors (with the initial nominee to be Holden Spaht), and such right will exist for so long as the seller parties and their controlled affiliates continue to beneficially own at least 10% of the shares of Nasdaq common stock outstanding as of November 1, 2023. The seller parties’ nominee to Nasdaq’s board of directors, Holden Spaht, is expected to remain on the board. In addition, the seller parties have agreed to be subject to a standstill obligation, including a restriction on acquiring shares in excess of 19.99% of the outstanding shares of common stock on a fully diluted basis, subject to certain exceptions, until at least November 1, 2025.

For more information on these relationships and the Stockholders’ Agreement and Registration Rights Agreement, please refer to the Annual Report on Form 10-K for our most recent fiscal year, which is incorporated herein by reference.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS OF COMMON STOCK

The following is a general discussion of certain material U.S. federal income tax considerations with respect to the ownership and disposition of shares of our common stock applicable to non-U.S. holders (defined below) who acquired such shares in this offering. This discussion is based upon current provisions of the Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations promulgated thereunder, administrative rulings of the U.S. Internal Revenue Service (the “IRS”), and judicial decisions, each as in effect on the date hereof. These authorities are subject to change and differing interpretations, possibly with retroactive effect, and any such change or differing interpretation could result in U.S. federal income tax consequences different from those discussed below.

For purposes of this discussion, the term “non-U.S. holder” means a beneficial owner of shares of our common stock that is not, for U.S. federal income tax purposes:

This discussion is limited to non-U.S. holders that acquire shares of our common stock pursuant to this offering and hold such shares as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a non-U.S. holder in light of that non-U.S. holder’s particular circumstances or that may be applicable to non-U.S. holders subject to special treatment under U.S. federal income tax laws (including, without limitation, banks, insurance companies or other financial institutions; tax-exempt entities; “controlled foreign corporations,” “passive foreign investment companies” and corporations that accumulate earnings to avoid U.S. federal income tax; entities or arrangements treated as partnerships for U.S. federal income tax purposes or other “flow-through” entities and investors therein; brokers or dealers in securities or currencies; traders in securities that elect mark-to-market treatment; real estate investment trusts or regulated investment companies; certain former citizens or long-term residents of the United States; or holders who hold our common stock as part of a straddle, hedge, conversion transaction, constructive sale, or other integrated security transaction). In addition, this discussion does not address U.S. federal tax laws other than those pertaining to the U.S. federal income tax, nor does it address any aspects of the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010. Prospective investors should consult their tax advisors regarding the U.S. federal, state, local, and non-U.S. income and other tax considerations with respect to acquiring, holding and disposing of shares of our common stock.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our common stock, the tax treatment of a person treated as a partner in such partnership generally will depend on the status of the partner and the activities of the partnership. Persons that for U.S. federal income tax purposes are treated as partnerships and partners in such partnerships should consult their tax advisors.

This discussion is for general information only and is not intended to constitute a complete description of all tax considerations relating to the acquisition, ownership and disposition of our common stock.

S-19

Prospective holders of our common stock should consult with their tax advisors regarding the tax consequences to them of the acquisition, ownership and disposition of our common stock, including the application and effect of any U.S. federal, state, local, and non-U.S. income and other tax laws.

Distributions

In general, subject to the discussion below regarding “effectively connected” dividends, the gross amount of any distribution we make to a non-U.S. holder with respect to its shares of our common stock will be subject to U.S. federal withholding tax at a rate of 30% to the extent that the distribution constitutes a dividend for U.S. federal income tax purposes, unless the non-U.S. holder is eligible for an exemption from, or a reduced rate of, such withholding tax under an applicable income tax treaty and the non-U.S. holder provides proper certification of its eligibility for such exemption or reduced rate. A distribution with respect to shares of our common stock will constitute a dividend for U.S. federal income tax purposes to the extent of our current or accumulated earnings and profits, as determined for U.S. federal income tax purposes. To the extent any distribution does not constitute a dividend, it will be treated first as reducing the adjusted tax basis in the non-U.S. holder’s shares of our common stock and then, to the extent it exceeds the non-U.S. holder’s adjusted tax basis in its shares of our common stock, as gain from the sale or exchange of such stock. Any such gain will be subject to the tax treatment described below under “Gain on Sale or Other Taxable Disposition of Common Stock.”

Dividends we pay with respect to our common stock to a non-U.S. holder that are effectively connected with the conduct by such non-U.S. holder of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or a fixed base of such non-U.S. holder in the United States) generally will not be subject to U.S. federal withholding tax, as described above, if the non-U.S. holder complies with applicable certification and disclosure requirements. Instead, such dividends generally will be subject to U.S. federal income tax on a net income basis at the U.S. federal income tax rates applicable to U.S. citizens, nonresident aliens or domestic corporations, as applicable. Dividends received by a non-U.S. holder that is a corporation and that are effectively connected with its conduct of a trade or business within the United States may be subject to an additional “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty).

Gain on Sale or Other Taxable Disposition of Common Stock

Subject to the discussion below under “—Information Reporting and Backup Withholding” and “FATCA,” in general, a non-U.S. holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other disposition of the non-U.S. holder’s shares of our common stock unless:

Gain described in the first bullet point immediately above generally will be subject to U.S. federal income tax on a net income tax basis at the U.S. federal income tax rates applicable to U.S. citizens, nonresident aliens or domestic corporations, as applicable. A non-U.S. holder that is a corporation and that recognizes gain described in the first bullet point immediately above may also be subject to the branch profits tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) with respect to such effectively connected gain, as adjusted for certain items.

S-20

An individual non-U.S. holder described in the second bullet point immediately above will be subject to a flat 30% tax (unless the non-U.S. holder is eligible for a lower rate under an applicable income tax treaty) on the gain from such sale or other disposition, which may be offset by U.S.-source capital losses, if any, of the non-U.S. holder, provided the non-U.S. holder has timely filed U.S. federal income tax returns with respect to such losses.

We believe we are not, and do not anticipate becoming, a USRPHC for U.S. federal income tax purposes. However, no assurance can be given that we are not or will not become a USRPHC. If we were or were to become a USRPHC, however, any gain recognized on a sale or other disposition of shares of our common stock by a non-U.S. holder that did not own (directly, indirectly or constructively) more than 5% of our common stock during the applicable period would not be subject to U.S. federal income tax, provided that our common stock is “regularly traded on an established securities market” (within the meaning of Section 897(c)(3) of the Code).

Information Reporting and Backup Withholding

We must report annually to the IRS and to each non-U.S. holder the amount of distributions paid to such non-U.S. holder and the tax withheld with respect to such distributions. These reporting requirements apply regardless of whether withholding was reduced or eliminated by an applicable tax treaty.

A non-U.S. holder generally will be subject to backup withholding (currently at a rate of 24%) on dividends paid with respect to such non-U.S. holder’s shares of our common stock unless such holder certifies under penalties of perjury that, among other things, it is a non-U.S. holder (and the payor does not have actual knowledge, or reason to know, that such holder is a United States person (as defined in the Code)) or otherwise establishes an exemption.

Information reporting and backup withholding generally are not required with respect to any proceeds from the sale or other disposition of our common stock by a non-U.S. holder outside of the United States through a foreign office of a foreign broker that does not have certain specified connections to the United States. However, if a non-U.S. holder sells or otherwise disposes of its shares of our common stock through a U.S. broker or the U.S. offices of a foreign broker, the broker will generally be required to report the amount of proceeds paid to the non-U.S. holder to the IRS and may also be required to backup withhold on such proceeds unless such non-U.S. holder certifies under penalties of perjury that, among other things, it is a non-U.S. holder (and the payor does not have actual knowledge, or reason to know, that such holder is a United States person (as defined in the Code)) or otherwise establishes an exemption. Information reporting will also apply if a non-U.S. holder sells its shares of our common stock through a foreign broker with certain specified connections to the United States, unless such broker has documentary evidence in its records that such non-U.S. holder is not a United States person and certain other conditions are met, or such non-U.S. holder otherwise establishes an exemption (and the payor does not have actual knowledge, or reason to know, that such holder is a United States person (as defined in the Code)).

Copies of any information returns may also be made available to the tax authorities in the country in which the non-U.S. holder resides or is established under the provisions of an applicable income tax treaty or agreement.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder may be credited against the non-U.S. holder’s U.S. federal income tax liability, if any, or refunded, provided that the required information is furnished to the IRS in a timely manner. Non-U.S. holders should consult their tax advisors regarding the application of the information reporting and backup withholding rules to them.

S-21

FATCA

Under Sections 1471 through 1474 of the Code (such Sections and the U.S. Treasury regulations promulgated thereunder, collectively, commonly referred to as “FATCA”), a U.S. federal withholding tax at a rate of 30% generally will be imposed on certain payments made to a “foreign financial institution” (as specifically defined under FATCA) unless such institution enters into an agreement with the U.S. tax authorities to withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or meets other exceptions. Under the legislation and administrative guidance, a U.S. federal withholding tax of 30% generally also will be imposed on certain payments made to a non-financial foreign entity unless such entity provides the withholding agent with a certification identifying its direct and indirect U.S. owners or meets other exceptions. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. These withholding taxes would be imposed on dividends paid with respect to our common stock and (subject to proposed Treasury regulations described below) on gross proceeds from sales or other dispositions of our common stock. Proposed Treasury regulations issued in 2018, which state that taxpayers may rely on them until final regulations are issued, eliminate the U.S. federal withholding tax of 30% applicable to gross proceeds from sales or other dispositions of our common stock. Prospective non-U.S. holders should consult with their tax advisors regarding the possible implications of FATCA on their investment in our common stock.

S-22

UNDERWRITING

The company, the selling stockholders and Goldman Sachs & Co. LLC have entered into an underwriting agreement with respect to the shares being offered. Subject to certain conditions, the underwriter has agreed to purchase 41,604,207 shares of common stock from the selling stockholder at a price of $    per share, which will result in $    of proceeds to the selling stockholder before expenses. The underwriter is committed to take and pay for all of the shares being offered, if any are taken.

The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriter by the selling stockholder.

Paid by the Selling Stockholder

Shares sold by the underwriter to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus. Any shares sold by the underwriter to securities dealers may be sold at a discount of up to $    per share from the initial public offering price. After the initial offering of the shares, the underwriter may change the offering price and the other selling terms. The offering of the shares by the underwriter is subject to receipt and acceptance and subject to the underwriter’s right to reject any order in whole or in part.

We have agreed that, without the prior written consent of the underwriter, we will not, and will not publicly disclose an intention to, during the period ending 90 days after the date of this prospectus supplement (the “restricted period”): (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock; (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the common stock, whether any such transaction described in clauses (1) or (2) is to be settled by delivery of common stock or such other securities, in cash or otherwise; or (3) file any registration statement with the SEC relating to the offering of any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock.

In addition, each such person agrees that, without the prior written consent of the underwriter, such person will not, during the restricted period, make any demand for, or exercise any right with respect to, the registration of any shares of common stock or any security convertible into or exercisable or exchangeable for common stock.

The restrictions described in the immediately preceding paragraph to do not apply to:

provided, (A) in the case of any transfer pursuant to clauses (i) and (iii) no filing under Section 16(a) of the Exchange Act reporting a reduction in beneficial ownership is required or voluntarily made, (B) in the case of clause (ii), no filing under Section 16(a) of the Exchange Act is voluntarily made and, if any filing is legally required, such filing indicates the report relates to the circumstances described in clause (ii) above, (C) in the case of any transfer pursuant to clauses (ii), (iii), (iv), and (vi) that the recipient of the securities enters into a lock-up agreement substantially in the form entered into by the Selling Stockholder or the common stock so transferred otherwise remains subject to the restrictions of the lock-up agreement, and (D) in the case of any transfer pursuant to clauses (ii), (iii) and (iv) such transfer shall not involve a disposition for value, and (E) in the case of any transfer pursuant to clauses (iv), (v), (vi) and (vii) if any filing is made under Section 16(a) of the Exchange Act, such filing shall indicate the nature and conditions of such transfer.

The selling stockholder has agreed that, without the prior written consent of the underwriter, the selling stockholder will not, and will not publicly disclose an intention to, during the restricted period, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock, or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the common stock, whether any such transaction described in clauses (1) or (2) is to be settled by delivery of common stock or such other securities, in cash or otherwise.

The restrictions described in the immediately preceding paragraph to do not apply to:

S-25

provided, (A) in the case of any transfer pursuant to clause (ii) no filing under Section 16(a) of the Exchange Act reporting a reduction in beneficial ownership is required or voluntarily made, (B) in the case of any transfer pursuant to clauses (iii) and (iv) that the recipients of the securities enters into a lock-up agreement substantially in the form entered into by the Selling Stockholder, and (C) in the case of any transfer pursuant to clauses (iii) and (iv) no filing under Section 16(a) of the Exchange Act shall be voluntarily made and, if any filing is required, such filing shall indicate the nature and conditions of such transfer.

The representatives, in their sole discretion, may release the common stock and other securities subject to the lock-up agreements described above in whole or in part at any time.

In connection with the offering, the underwriter may purchase and sell shares of common stock in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriter of a greater number of shares than they are required to purchase in the offering, and a short position represents the amount of such sales that have not been covered by subsequent purchases. A “covered short position” is a short position that is not greater than the amount of additional shares for which the underwriter’s option described above may be exercised. The underwriter may cover any covered short position by either exercising its option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to cover the covered short position, the underwriter will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase additional shares pursuant to the option described above. “Naked” short sales are any short sales that create a short position greater than the amount of additional shares for which the option described above may be exercised. The underwriter must cover any such naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of common stock made by the underwriter in the open market prior to the completion of the offering.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriter for its own account, may have the effect of preventing or retarding a decline in the market price of the company’s stock, and may stabilize, maintain or otherwise affect the market price of the common stock. As a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. The underwriter is not required to engage in these activities and may end any of these activities at any time. These transactions may be effected on The Nasdaq Stock Market, in the over-the-counter market or otherwise.

European Economic Area

In relation to each Member State of the European Economic Area (each, a “Relevant Member State”), an offer to the public of any shares may not be made in that Relevant Member State, except that an offer to the public in that Relevant Member State of any shares may be made at any time under the following exemptions under the EU Prospectus Regulation:

provided that no such offer of shares shall result in a requirement for the Company or the underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or a supplemental prospectus pursuant to Article 23 of the Prospectus Regulation and each person who initially acquires any shares or to whom any offer is made will be deemed to have represented, warranted and agreed to and with the underwriter and the Company that it is a qualified investor within the meaning of Article 2 of the EU Prospectus Regulation.

In the case of any shares being offered to a financial intermediary as that term is used in Article 1(4) of the EU Prospectus Regulation, each financial intermediary will also be deemed to have represented, warranted and agreed that the shares acquired by it in the offer have not been acquired on a non-discretionary basis on behalf of, nor have they been acquired with a view to their offer or resale to, persons in circumstances which may give rise to an offer of any shares to the public, other than their offer or resale in a Relevant Member State to qualified investors as so defined or in circumstances in which the prior consent of the underwriter has been obtained to each such proposed offer or resale.

The Company, the underwriter and their affiliates will rely upon the truth and accuracy of the foregoing representations, warranties and agreements. Notwithstanding the above, a person who is not a “qualified investor” and who has notified the underwriter of such fact in writing may, with the prior consent of the underwriter, be permitted to acquire shares in the offer.

For the purposes of this provision, the expression an “offer to the public” in relation to any shares in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and any shares to be offered so as to enable an investor to decide to purchase or subscribe for any shares, and the expression “EU Prospectus Regulation” means Regulation (EU) 2017/1129.

United Kingdom

An offer to the public of any shares may not be made in the United Kingdom, except that an offer to the public in the United Kingdom of any shares may be made at any time under the following exemptions under the UK Prospectus Regulation:

provided that no such offer of shares shall result in a requirement for the Company or the underwriter to publish a prospectus pursuant to section 85 of the FSMA or a supplemental prospectus pursuant to Article 23 of the UK Prospectus Regulation and each person who initially acquires any shares or to whom any offer is made will be

S-27

deemed to have represented, warranted and agreed to and with the underwriter and the Company that it is a qualified investor within the meaning of Article 2 of the UK Prospectus Regulation.

In the case of any shares being offered to a financial intermediary as that term is used in Article 1(4) of the UK Prospectus Regulation, each financial intermediary will also be deemed to have represented, warranted and agreed that the shares acquired by it in the offer have not been acquired on a non-discretionary basis on behalf of, nor have they been acquired with a view to their offer or resale to, persons in circumstances which may give rise to an offer of any shares to the public, other than their offer or resale in the United Kingdom to qualified investors as so defined or in circumstances in which the prior consent of the underwriter has been obtained to each such proposed offer or resale.

The Company, the underwriter and their affiliates will rely upon the truth and accuracy of the foregoing representations, warranties and agreements. Notwithstanding the above, a person who is not a “qualified investor” and who has notified the underwriter of such fact in writing may, with the prior consent of the underwriter, be permitted to acquire shares in the offer.

For the purposes of this provision, the expression an “offer to the public” in relation to any shares in the United Kingdom means the communication in any form and by any means of sufficient information on the terms of the offer and any shares to be offered so as to enable an investor to decide to purchase or subscribe for any shares.

This Prospectus is only being distributed to and is only directed at: (A) persons who are outside the United Kingdom; or (B) qualified investors who are also (i) investment professionals falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 (the “Order”), or (ii) high net worth companies, and other persons to whom it may lawfully be communicated, falling within Article 49(2)(a) to (d) of the Order (all such persons falling within (1)-(3) together being referred to as “relevant persons”). The shares are only available to, and any invitation, offer or agreement to subscribe, purchase or otherwise acquire the shares will be engaged in only with, relevant persons. Any person who is not a relevant person should not act or rely on this Prospectus or any of its contents.

Any resale of the securities must be made in accordance with an exemption form, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this offering memorandum (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement and documents incorporated by reference herein and therein may include forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. We intend that the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 apply to these forward-looking statements. Forward-looking statements are not statements of historical fact but rather reflect our current expectations, estimates and predictions about future results and events. Words such as “may,” “will,” “could,” “should,” “anticipates,” “envisions,” “estimates,” “expects,” “projects,” “intends,” “plans,” “believes” and words or terms of similar substance used in connection with any discussion of future expectations as to industry and regulatory developments or business initiatives and strategies, future operating results or financial performance, and other future developments are intended to identify forward-looking statements. These include, among others, statements relating to:

Forward-looking statements involve risks and uncertainties. Factors that could cause actual results to differ materially from those contemplated by the forward-looking statements include, among others, the following:

3

Most of these factors are difficult to predict accurately and are generally beyond our control. You should consider the uncertainty and any risk related to forward-looking statements that we make. The above list of risks and uncertainties is only a summary of some of the most important factors and is not intended to be exhaustive. You should carefully review the risks and information contained, or incorporated by reference, in this prospectus, including, without limitation, those risk factors discussed under the caption “Part I. Item 1A. Risk Factors,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 that was filed with the SEC on February 21, 2024 and in any reports subsequently filed with the SEC. New factors that are not currently known to us or of which we are currently unaware may also emerge from time to time that could materially and adversely affect us. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this prospectus. You should carefully read our entire Annual Report on Form 10-K, including “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the consolidated financial statements and the related notes contained therein. Except as required by the federal securities laws, we undertake no obligation to update any forward-looking statement, release publicly any revisions to any forward-looking statements or report the occurrence of unanticipated events. For any forward-looking statements contained in any document, we claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

DESCRIPTION OF CAPITAL STOCK

General

The following summary description of our capital stock is based on the provisions of the Delaware General Corporate Law (the “DGCL”), our amended and restated certificate of incorporation, and our bylaws. This description does not purport to be complete and is qualified in its entirety by reference to the full text of the DGCL, as it may be amended from time to time, and to the terms of our amended and restated certificate of incorporation and bylaws, as each may be amended from time to time, which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information.” As used in this “Description of Capital Stock,” the terms “Nasdaq, Inc.,”, “Nasdaq,” the “Company”, “we,” “our” and “us” refer to Nasdaq, Inc., a Delaware corporation, and do not, unless otherwise specified, include our subsidiaries.

Our authorized capital stock consists of (i) 900,000,000 shares of common stock, par value $0.01 per share, and (ii) 30,000,000 shares of preferred stock, par value $0.01 per share. As of March 31, 2024, there were 575,758,581 shares of our common stock outstanding and no shares of preferred stock outstanding. As of March 31, 2024, we had approximately 201 holders of record of our common stock.

Common Stock

Each stockholder of record of our common stock is entitled to one vote for each share held on every matter properly submitted to the stockholders for their vote. Holders of our common stock do not have cumulative voting rights. The holders of our common stock are entitled to one vote per share, except that our certificate of incorporation limits the ability of any stockholder to vote in excess of 5.0% of the then-outstanding shares of our common stock. This limitation does not apply to persons exempted from this limitation by our board of directors prior to the time such person owns more than 5.0% of the then-outstanding shares of our common stock.

After satisfaction of any dividend rights of holders of preferred stock, if any, holders of common stock are entitled ratably to any dividend declared by our board of directors out of funds legally available for this purpose.

Upon our liquidation, dissolution or winding up, the holders of our common stock are entitled to receive ratably our net assets available, if any, after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock.

Holders of our common stock have no preemptive, subscription, redemption, conversion or exchange rights and no sinking fund provisions.

The rights, preferences and privileges of holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock, if any, that we may designate and issue in the future.

Preferred Stock

This section describes the general terms and provisions of preferred stock that we are authorized to issue. An accompanying prospectus supplement will describe the specific terms of the shares of preferred stock offered through that prospectus supplement, as well as any general terms described in this section that will not apply to those shares of preferred stock. If there are differences between the prospectus supplement relating to a particular series of preferred stock and this prospectus, the prospectus supplement will control. We will file a copy of the certificate of amendment to our certificate of incorporation that contains the terms of each new series of preferred stock with the Secretary of the State of Delaware and with the SEC each time we issue a new series of preferred stock. Each such certificate of amendment will establish the number of shares included in a designated series and

13

fix the designation, powers, privileges, preferences and rights of the shares of each series as well as any applicable qualifications, limitations or restrictions. You should refer to the applicable certificate of amendment as well as our certificate of incorporation before deciding to buy shares of our preferred stock as described in any accompanying prospectus supplement.

Our board of directors has been authorized to provide for the issuance of up to 30,000,000 shares of our preferred stock in multiple series without the approval of stockholders. With respect to each series of our preferred stock, our board of directors has the authority to fix the following terms:

The right of a holder of preferred stock to receive payment in respect thereof upon any liquidation, dissolution or winding up of us will be subordinate to the rights of our general creditors.

Anti-Takeover Effects of Provisions of the Certificate of Incorporation, Bylaws and Other Agreements

Our amended and restated certificate of incorporation and our by-laws contain provisions that may make it more difficult for a potential acquirer to acquire us by means of a transaction that is not negotiated with our board of directors. These provisions and certain provisions of the DGCL could delay or prevent a merger or acquisition that our stockholders consider favorable. These provisions may also discourage acquisition proposals or have the effect of delaying or preventing a change in control, which could harm our stock price. The following is a description of the anti-takeover effects of certain provisions of our amended restated certificate of incorporation and our by-laws.

Advance Notice Requirements for Stockholder Proposals and Directors Nominations: Our by-laws provide that stockholders seeking to bring business before an annual meeting of stockholders, or to nominate candidates for election as directors at an annual meeting of stockholders, must provide timely notice in writing.

Generally, a stockholder’s notice must be delivered to or mailed and received at our principal executive offices not less than 90 nor more than 120 days prior to the anniversary date of the immediately preceding annual meeting of stockholders; provided, that in the event that the annual meeting is called for a date that is not within 30 days before or 70 days after such anniversary date, notice by the stockholder in order to be timely must be received no earlier than 120 days prior to the meeting and not later than the later of 90 days prior to the meeting and the close of business on the 10th day following the date on which notice of the date of the annual meeting was first publicly announced by Nasdaq. In the case of a special meeting of stockholders called for the purpose of electing directors, notice by the stockholder in order to be timely must be received no earlier than 120 days prior to the meeting and not later than the later of 90 days prior to the meeting or the close of business on the 10th day

14

following the day on which public disclosure of the date of the special meeting and our nominees was first made. In addition, the by-laws specify certain requirements as to the form and content of a stockholder’s notice. These provisions may impede stockholders’ ability to bring matters before an annual meeting of stockholders, a stockholder requested special meeting of stockholders or make nominations for directors.

Proxy Access: Our by-laws include a proxy access provision that permits a stockholder, or a group of stockholders, owning at least 3% of our outstanding shares of common stock continuously for at least three years to nominate and include in the proxy materials for an annual meeting of stockholders director nominees constituting up to the greater of two individuals and 25% of the total number of directors then in office, provided that the stockholder(s) and nominee(s) satisfy the requirements specified in the by-laws.

No Cumulative Voting: The DGCL provides that stockholders of a Delaware corporation are not entitled to the right to cumulate votes in the election of directors unless the corporation’s certificate of incorporation, as amended, provides otherwise. Our amended and restated certificate of incorporation does not provide for cumulative voting.

No Action by Written Consent: Our certificate of incorporation provides that stockholders are not entitled to act by written consent in lieu of a meeting.

Right to Call Special Meeting: Our by-laws provide that only stockholders representing 15% or more, in the aggregate, of our outstanding shares can convene a special meeting of stockholders, provided that the stockholders satisfy the requirements of our by-laws.

Amendments; Vote Requirements: The DGCL provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation, unless a corporation’s certificate of incorporation requires a greater percentage. Our certificate of incorporation imposes majority voting requirements in connection with stockholder amendments to the by-laws and in connection with the amendment of certain provisions of the certificate of incorporation, including those provisions of our certificate of incorporation relating to the limitations on voting rights of certain persons, removal of directors and prohibitions on stockholder action by written consent.

Authorized but Unissued Shares: The authorized but unissued shares of our common stock and preferred stock will be available for future issuance without stockholder approval in most cases. These additional shares may be utilized for a variety of corporate purposes, including future public or private offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of our 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.

General Corporation Law of the State of Delaware: We are a Delaware corporation that is subject to Section 203 of the DGCL. Section 203 provides that, subject to certain exceptions specified in the law, a Delaware corporation shall not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder unless:

15

Generally, a “business combination” includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an “interested stockholder” is a person who, together with that person’s affiliates and associates, owns, or within the previous three years did own, 15% or more of our voting stock.

Under certain circumstances, Section 203 makes it more difficult for a person who would be an “interested stockholder” to effect various business combinations with a corporation for a three-year period. The provisions of Section 203 may encourage any entity interested in acquiring our Company 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 that results in such entity becoming an interested stockholder. These provisions also may make it more difficult to accomplish transactions involving our Company that our stockholders may otherwise deem to be in their best interests.

Listing

Our common stock is listed on The Nasdaq Stock Market under the symbol “NDAQ.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare.

16

DESCRIPTION OF DEPOSITARY SHARES

We may offer depositary receipts representing fractional shares of our preferred stock, rather than full shares of preferred stock. The shares of preferred stock represented by depositary shares will be deposited under a depositary agreement between us and a bank or trust company that meets certain requirements and is selected by us (the “Bank Depositary”). Each owner of a depositary share will be entitled to all the rights and preferences of the preferred stock represented by the depositary share.

The description in an accompanying prospectus supplement of any depositary shares we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable depositary agreement, which will be filed with the SEC if we offer depositary shares. For more information on how you can obtain copies of any depositary agreement if we offer depositary shares, see “Where You Can Find More Information.” We urge you to read the applicable depositary agreement and any accompanying prospectus supplement in their entirety.

Dividends and Other Distributions

If we pay a cash distribution or dividend on a series of preferred stock represented by depositary shares, the Bank Depositary will distribute such dividends to the record holders of such depositary shares. If the distributions are in property other than cash, the Bank Depositary will distribute the property to the record holders of the depositary shares. However, if the Bank Depositary determines that it is not feasible to make the distribution of property, the Bank Depositary may, with our approval, sell such property and distribute the net proceeds from such sale to the record holders of the depositary shares.

Redemption of Depositary Shares

If we redeem a series of preferred stock represented by depositary shares, the Bank Depositary will redeem the depositary shares from the proceeds received by the Bank Depositary in connection with the redemption. The redemption price per depositary share will equal the applicable fraction of the redemption price per share of the preferred stock. If fewer than all the depositary shares are redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as the Bank Depositary may determine.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock represented by depositary shares are entitled to vote, the Bank Depositary will mail the notice to the record holders of the depositary shares relating to such preferred stock. Each record holder of these depositary shares on the record date, which will be the same date as the record date for the preferred stock, may instruct the Bank Depositary as to how to vote the preferred stock represented by such holder’s depositary shares. The Bank Depositary will endeavor, insofar as practicable, to vote the amount of the preferred stock represented by such depositary shares in accordance with such instructions, and we will take all action that the Bank Depositary deems necessary in order to enable the Bank Depositary to do so. The Bank Depositary will abstain from voting shares of the preferred stock to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred stock.

Amendment and Termination of the Depositary Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the depositary agreement may be amended by agreement between the Bank Depositary and us. However, any amendment that materially and adversely alters the rights of the holders of depositary shares will not be effective unless such amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The depositary agreement may be terminated by the Bank Depositary or us only if (1) all outstanding depositary

17

shares have been redeemed or (2) there has been a final distribution in respect of the preferred stock in connection with any liquidation, dissolution or winding up of our Company and such distribution has been distributed to the holders of depositary receipts.

Withdrawal of Preferred Stock

Except as may be provided otherwise in an accompanying prospectus supplement, upon surrender of depositary receipts at the principal office of the Bank Depositary, subject to the terms of the depositary agreement, the owner of the depositary shares may demand delivery of the number of whole shares of preferred stock and all money and other property, if any, represented by those depositary shares. Partial shares of preferred stock will not be issued. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the Bank Depositary will deliver to such holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Holders of withdrawn preferred stock may not thereafter deposit those shares under the depositary agreement or receive depositary receipts evidencing depositary shares therefor.

18

DESCRIPTION OF DEBT SECURITIES

We may offer debt securities in one or more series, which may be senior debt securities or subordinated debt securities and which may be convertible into another security.

The following description briefly sets forth certain general terms and provisions of the debt securities. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which the following general terms and provisions may apply to the debt securities, will be described in an accompanying prospectus supplement. Unless otherwise specified in an accompanying prospectus supplement, our debt securities will be issued in one or more series under an indenture between us and Wells Fargo Bank, National Association, as trustee, or such other trustee named therein. The indenture was previously filed and is incorporated by reference as an exhibit to the registration statement of which this prospectus forms a part, which you should review for additional information. The terms of the debt securities will include those set forth in the indenture and those made a part of the indenture by the Trust Indenture Act of 1939 (“TIA”). You should read the summary below, any accompanying prospectus supplement and the provisions of the indenture in their entirety before investing in our debt securities.

The aggregate principal amount of debt securities that may be issued under the indenture is unlimited. The prospectus supplement relating to any series of debt securities that we may offer will contain the specific terms of the debt securities. These terms may include, among others, the following:

19

General

We may sell the debt securities, including original issue discount securities, at par or at a substantial discount below their stated principal amount. Unless we inform you otherwise in a prospectus supplement, we may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series or any other series outstanding at the time of issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of securities under the indenture.

We will describe in an accompanying prospectus supplement any other special considerations for any debt securities we sell that are denominated in a currency or currency unit other than U.S. dollars. In addition, debt securities may be issued where the amount of principal and/or interest payable is determined by reference to one or more currency exchange rates, commodity prices, equity indices or other factors. Holders of such securities may receive a principal amount or a payment of interest that is greater than or less than the amount of principal or interest otherwise payable on such dates, depending upon the value of the applicable currencies, commodities, equity indices or other factors. Information as to the methods for determining the amount of principal or interest, if any, payable on any date, and the currencies, commodities, equity indices or other factors to which the amount payable on such date is linked will be described in an accompanying prospectus supplement.

United States federal income tax consequences and special considerations, if any, applicable to any such series will be described in an accompanying prospectus supplement.

We expect most debt securities to be issued in fully registered form without coupons and in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. Subject to the limitations provided in the indenture and in an accompanying prospectus supplement, debt securities that are issued in registered form may be transferred or exchanged at the designated corporate trust office of the trustee, without the payment of any service charge, other than any tax or other governmental charge payable in connection therewith.

20

Global Securities

Unless we inform you otherwise in an accompanying prospectus supplement, the debt securities of a series may be issued in whole or in part in the form of one or more global securities that will be deposited with, or on behalf of, a depositary identified in an accompanying prospectus supplement. Unless and until a global security is exchanged in whole or in part for the individual debt securities, a global security may not be transferred except as a whole by the depositary for such global security to a nominee of such depositary or by a nominee of such depositary to such depositary or another nominee of such depositary or by such depositary or any such nominee to a successor of such depositary or a nominee of such successor.

Governing Law

The indenture and the debt securities shall be construed in accordance with and governed by the laws of the State of New York.

21

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of shares of our common stock, shares of preferred stock or our debt securities. We may issue warrants independently or together with other securities, and they may be attached to or separate from the other securities. Each series of warrants will be issued under a separate warrant agreement that we will enter into with a bank or trust company, as warrant agent, as detailed in an accompanying prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation, or agency or trust relationship, with you.

The prospectus supplement relating to a particular issue of warrants will describe the terms of those warrants, including, when applicable:

After warrants expire they will become void. The prospectus supplement may provide for the adjustment of the exercise price of the warrants.

Warrants may be exercised at the appropriate office of the warrant agent or any other office indicated in an accompanying prospectus supplement. Before the exercise of warrants, holders will not have any of the rights of holders of the securities purchasable upon exercise and will not be entitled to payments made to holders of those securities.

The description in an accompanying prospectus supplement of any warrants we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable warrant agreement, which will be filed with the SEC if we offer warrants. For more information on how you can obtain copies of any warrant agreement if we offer warrants, see “Where You Can Find More Information.” We urge you to read the applicable warrant agreement and any accompanying prospectus supplement in their entirety.

22

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase shares of our common stock, shares of our preferred stock or our debt securities. We may issue subscription rights independently or together with any other offered security, which may or may not be transferable by the stockholder. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

The prospectus supplement relating to any subscription rights we may offer will contain the specific terms of the subscription rights. These terms may include the following:

23

DESCRIPTION OF PURCHASE CONTRACTS AND PURCHASE UNITS

We may issue purchase contracts, including contracts obligating holders to purchase from us, and obligating us to sell to the holders, a specified number of shares of our common stock, shares of our preferred stock or our debt securities at a future date or dates, which we refer to in this prospectus as purchase contracts. The price of the securities and the number of securities may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula set forth in the purchase contracts, and may be subject to adjustment under anti-dilution formulas. The purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and our debt securities or preferred securities or debt obligations of third parties, including U.S. treasury securities, or any combination of the foregoing, securing the holders’ obligations to purchase the securities under the purchase contracts, which we refer to herein as purchase units. The purchase contracts may require holders to secure their obligations under the purchase contracts in a specified manner. The purchase contracts also may require us to make periodic payments to the holders of the purchase contracts or the purchase units, as the case may be, or vice versa, and those payments may be unsecured or pre-funded in whole or in part.

The description in an accompanying prospectus supplement of any purchase contract or purchase unit we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable purchase contract or purchase unit, which will be filed with the SEC if we offer purchase contracts or purchase units. For more information on how you can obtain copies of any purchase contract or purchase unit we may offer, see “Where You Can Find More Information.” We urge you to read the applicable purchase contract or applicable purchase unit and any accompanying prospectus supplement in their entirety.

24

SELLING SECURITYHOLDERS

Information about selling securityholders, where applicable, will be set forth in a prospectus supplement, in a post-effective amendment or in filings we make with the SEC under the Exchange Act which are incorporated by reference into this prospectus.

25

PLAN OF DISTRIBUTION

We or the selling securityholders may sell the securities being offered hereby in one or more of the following ways from time to time:

In addition, we or the selling securityholders may enter into derivative or hedging transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with such a transaction, the third parties may sell securities covered by and pursuant to this prospectus and any accompanying prospectus supplement. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We or the selling securityholders may also loan or pledge securities covered by this prospectus and any accompanying prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and any accompanying prospectus supplement.

We or the selling securityholders will identify the specific plan of distribution in a prospectus supplement, including:

Underwriters, dealers and agents

If we or the selling securityholders use underwriters in an offering, we or the selling securityholders will execute an underwriting agreement with such underwriters and will specify the name of each underwriter and the terms of the transaction (including any underwriting discounts and other terms constituting compensation of the underwriters and any dealers) in a prospectus supplement. If we or the selling securityholders use an underwriting syndicate, the managing underwriter(s) will be specified on the cover of the prospectus supplement. If we or the selling securityholders use underwriters for a sale of securities, the underwriters will acquire the securities for their own accounts. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. Unless otherwise set forth in the prospectus supplement, the obligations of the underwriters to purchase the offered securities will be subject to conditions precedent and the underwriters will be obligated to purchase all of the offered securities if any are purchased.

26

If dealers are used in an offering, we or the selling securityholders may sell the securities to the dealers as principals. The dealers then may resell the securities to the public at varying prices which they determine at the time of resale. The names of the dealers and the terms of the transaction will be specified in a prospectus supplement.

If agents are used in an offering, the names of the agents and the terms of the agency will be specified in a prospectus supplement. Unless otherwise indicated in a prospectus supplement, the agents will act on a best-efforts basis for the period of their appointment.

Dealers and agents named in a prospectus supplement may be underwriters as defined in the Securities Act and any discounts or commissions they receive from us and any profit on their resale of the securities may be treated as underwriting discounts and commissions under the Securities Act. We or the selling securityholders will identify in the applicable prospectus supplement any underwriters, dealers or agents and will describe their compensation. We or the selling securityholders may have agreements with the underwriters, dealers and agents to indemnify them against specified civil liabilities, including liabilities under the Securities Act.

Underwriters, dealers or agents and their associates may engage in other transactions with and perform other services for us or the selling securityholders in the ordinary course of business.

If so indicated in a prospectus supplement, we or the selling securityholders will authorize underwriters or other persons acting as our agents to solicit offers by institutional investors to purchase securities pursuant to contracts providing for payment and delivery on a future date. We or the selling securityholders may enter contracts with commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutional investors. The obligations of any institutional investor will be subject to the condition that its purchase of the offered securities will not be illegal at the time of delivery. The underwriters and other agents will not be responsible for the validity or performance of contracts.

Direct sales

We or the selling securityholders may sell securities directly to one or more purchasers without using underwriters or agents.

At-the-market offerings

We or the selling securityholders may also sell the securities offered by any applicable prospectus supplement in “at-the-market offerings” within the meaning of Rule 415 of the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise.

Trading markets and listing of securities

Unless otherwise specified in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other than our common stock, which is listed on The Nasdaq Stock Market. We may elect to list any other class or series of securities on any exchange, but we are not obligated to do so. It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the securities.

Stabilization activities

In connection with an offering, an underwriter may purchase and sell securities in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required to

27

purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional securities, if any, from us in the offering. If the underwriters have an over-allotment option to purchase additional securities from us, the underwriters may close out any covered short position by either exercising their over-allotment option or purchasing securities in the open market. In determining the source of securities to close out the covered short position, the underwriters may consider, among other things, the price of securities available for purchase in the open market as compared to the price at which they may purchase securities through the over-allotment option. “Naked” short sales are any sales in excess of such option or where the underwriters do not have an over-allotment option. The underwriters must close out any naked short position by purchasing securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the securities in the open market after pricing that could adversely affect investors who purchase in the offering.

Accordingly, to cover these short sales positions or to otherwise stabilize or maintain the price of the securities, the underwriters may bid for or purchase securities in the open market and may impose penalty bids. If penalty bids are imposed, selling concessions allowed to syndicate members or other broker-dealers participating in the offering are reclaimed if securities previously distributed in the offering are repurchased, whether in connection with stabilization transactions or otherwise. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. The impositions of a penalty bid may also affect the price of the securities to the extent that it discourages resale of the securities. The magnitude or effect of any stabilization or other transactions is uncertain. These transactions may be effected on The Nasdaq Stock Market or otherwise and, if commenced, may be discontinued at any time.
