Preliminary Prospectus Supplement

(to prospectus dated April 30, 2021)

€                    

        % Senior Notes due 20    

Nasdaq, Inc. (the “Company” or “we”) is offering €             million aggregate principal amount of    % Senior Notes due 20     (the “Notes”).

The Notes will bear interest at a rate of    % per year and will mature on                 , 20    . We will pay interest on the Notes annually in arrears on                 of each year, beginning on                 , 20    .

We may redeem the Notes in whole at any time, or in part, from time to time, at our option at any time prior to                 , 20     (     months before their maturity date), at the “make-whole” redemption price applicable to the Notes described under “Description of the Notes—Redemption—Optional Redemption.” At any time on or after                 , 20     (     months before their maturity date), the Notes will be redeemable, in whole at any time, or in part, from time to time, at our option, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

If a Change of Control Triggering Event (as defined in “Description of the Notes”) in respect of the Notes occurs, we will be required to offer to purchase the Notes from holders on terms described in this prospectus supplement.

If (x) the consummation of the Adenza Transaction (as defined herein) does not occur on or before the later of (i) the date that is five (5) business days after September 10, 2024 and (ii) the date that is five (5) business days after any later date to which Seller and we may agree to extend the “Outside Date” in the Adenza Transaction Agreement or (y) we notify the Trustee (as defined herein) that we will not pursue the consummation of the Adenza Transaction, we will be required to redeem the Notes at a redemption price equal to 101% of the aggregate principal amount of the Notes, plus accrued and unpaid interest, if any, to, but excluding the special mandatory redemption date (as defined herein). See “Description of the Notes—Redemption—Special Mandatory Redemption.”

The Notes will be issued in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof.

The Notes will be unsubordinated unsecured obligations of ours and will rank equally in right of payment with all of our existing and future unsubordinated unsecured obligations. The Notes will not be guaranteed by any of our subsidiaries.

Currently, there is no public market for the Notes. We intend to apply to list the Notes on The Nasdaq Global Market. There can be no assurance that this application will be accepted.

Investing in the Notes involves risks. See the “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022, which is incorporated by reference into this prospectus supplement and the accompanying prospectus and the risks beginning on page S-23 of this prospectus supplement.

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

The Notes will be ready for delivery in book-entry form only through the facilities of Euroclear Bank SA/NV (“Euroclear”) and Clearstream Banking, S.A., Luxembourg (“Clearstream”) on or about                 , 2023.

PROHIBITION OF SALES TO EEA RETAIL INVESTORS

The debt securities described in this prospectus supplement are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, a retail investor means a person who is one (or more) of (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, “MiFID II”), (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II or (iii) not a qualified investor as defined in the Regulation (EU) 2017/1129 (as amended, the “Prospectus Regulation”). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering, selling or distributing the debt securities described in this prospectus supplement or otherwise making them available to retail investors in the EEA has been prepared and therefore offering, selling or distributing such debt securities or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement has been prepared on the basis that any offer of such debt securities in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of such debt securities. This prospectus supplement is not a prospectus for the purposes of the Prospectus Regulation.

PROHIBITION OF SALES TO UK RETAIL INVESTORS

The debt securities described in this prospectus supplement are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom. For these purposes, a retail investor means a person who is one (or more) of (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (“EUWA”), (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, “FSMA”) and any rules or regulations made under the FSMA to implement the Insurance Distribution Directive, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA (the “UK Prospectus Regulation”). Consequently, no key information document required by PRIIPs Regulation as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering, selling or distributing the Notes or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering, selling or distributing the Notes or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the UK PRIIPs Regulation. This prospectus supplement has been prepared on the basis that any offer of such debt securities in the United Kingdom will be made pursuant to an exemption under the UK Prospectus Regulation from the requirement to publish a prospectus for offers of such debt securities.

MIFID II PRODUCT GOVERNANCE/PROFESSIONAL INVESTORS AND ELIGIBLE COUNTERPARTIES ONLY TARGET MARKET

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the debt securities described in this prospectus supplement has led to the conclusion that: (i) the target market for such debt securities is eligible counterparties and professional clients only, each as defined in MiFID II and (ii) all channels for distribution of such debt securities to eligible counterparties and professional clients are appropriate.

FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus 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:

S-4

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 supplement, 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, 2022 that was filed with the SEC on February 23, 2023 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 the Notes 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 the Notes offered by this prospectus supplement.

Risks Relating to the Notes

The Notes will be structurally junior to the indebtedness and other liabilities of our subsidiaries.

We are a holding company with minimal direct operating businesses other than the equity interests of our subsidiaries. We require dividends and other payments from our subsidiaries to meet cash requirements and to pay dividends on our common stock. Minimum capital requirements mandated by regulatory authorities having jurisdiction over some of our regulated subsidiaries indirectly restrict the amount of dividends paid upstream. If our subsidiaries are unable to pay dividends and make other payments to us when needed, we may be unable to satisfy our obligations, which would have a material adverse effect on our business, financial condition and operating results.

You will not have any claim as a creditor against our subsidiaries, and all existing and future indebtedness and other liabilities, including trade payables, whether secured or unsecured, of those subsidiaries will be structurally senior to the Notes. Furthermore, in the event of any bankruptcy, liquidation or reorganization of any of our subsidiaries, the rights of the holders of the Notes to participate in the assets of such subsidiary will rank behind the claims of that subsidiary’s creditors, including trade creditors (except to the extent we have a claim as a creditor of such subsidiary). As a result, the Notes will be structurally subordinated to the outstanding indebtedness and other liabilities, including trade payables, of our subsidiaries, which may be material.

As of March 31, 2023, after giving effect to this offering and incurrences of debt under the Bridge Facility or anticipated replacements thereof (including the Dollar Offering and the new term loan facility) and any other debt incurred to finance the Adenza Transaction, our direct and indirect subsidiaries had no indebtedness outstanding to which the Notes would have been structurally subordinated. Our subsidiaries generate substantially all of our revenues and net income and own substantially all of our assets. As of March 31, 2023, giving effect to the Adenza Transaction, our subsidiaries held approximately 97% of our consolidated assets. In addition, the indenture will not restrict these subsidiaries from incurring additional indebtedness and will not contain any limitation on the amount of other liabilities, such as trade payables, that may be incurred by these subsidiaries.

The Notes will be effectively subordinated to all of our existing and future secured indebtedness and other secured obligations.

The Notes will not be secured by any of our assets. As a result, the indebtedness represented by the Notes will be effectively subordinated to any existing and future secured indebtedness we have incurred or may incur, as well as to other secured obligations, in each case to the extent of the value of the assets securing such indebtedness. The terms of the indenture will permit us to incur secured debt subject to certain limitations, and the amount of such secured debt could be significant. In addition, the indenture will not contain any limitation on our ability to incur secured obligations that do not constitute indebtedness. In the event of any distribution or payment of our assets in any foreclosure, dissolution, winding up, liquidation or reorganization, or other bankruptcy proceeding, any secured creditors would have a claim to their collateral superior to that of the Notes. See “Description of the Notes—Certain Covenants—Limitations on Liens.”

S-23

Downgrades or other changes in our credit ratings could affect our financial results and reduce the market value of the Notes.

The credit ratings assigned to the Notes may not reflect the potential impact of all risks related to trading markets, if any, for, or trading value of, the Notes. A rating is not a recommendation to purchase, hold or sell our debt securities, since a rating does not predict the market price of a particular security or its suitability for a particular investor. Any rating organization may lower our rating or decide not to rate our securities in its sole discretion. The rating of our debt securities is based primarily on the rating organization’s assessment of the likelihood of timely payment of interest when due on our debt securities and the ultimate payment of principal of our debt securities on the final maturity date. Any ratings downgrade could decrease the value of the Notes, increase our cost of borrowing or require certain actions to be performed to rectify such a situation. The reduction, suspension or withdrawal of the ratings of our debt securities will not, in and of itself, constitute an event of default under the indenture governing the Notes.

We may choose to redeem the Notes when prevailing interest rates are relatively low.

The Notes are redeemable at any time at our option, and we may choose to redeem some or all of the Notes from time to time, especially when prevailing interest rates are lower than the rates borne by the Notes. If prevailing rates are lower at the time of redemption, you may not be able to reinvest the redemption proceeds in a comparable investment at an effective interest rate as high as the interest rates on the Notes being redeemed. See “Description of the Notes—Redemption—Optional Redemption.”

There is no current public market for the Notes and a market may not develop.

The Notes are new securities for which there is currently no established market. We cannot guarantee:

Liquidity of any market for the Notes and future trading prices of the Notes will depend on many factors, including:

The underwriters have advised us that they currently intend to make markets in the Notes, but they are not obligated to do so and may cease any market-making at any time without notice. Although we intend to apply for listing of the Notes for trading on The Nasdaq Global Market, we cannot assure you that the Notes will become or remain traded. Although no assurance is made as to the liquidity of the Notes as a result of the admission to trading on The Nasdaq Global Market, failure to be approved for listing or the delisting of the Notes, as applicable, may have a material effect on a holder’s ability to resell the Notes in the secondary market.

The indenture governing the Notes will not limit our ability to incur future indebtedness, pay dividends, repurchase securities, engage in transactions with affiliates or engage in other activities, which could adversely affect our ability to pay our obligations under the Notes.

The indenture governing the Notes will not contain any financial maintenance covenants and will contain only limited restrictive covenants. The indenture will not limit our or our subsidiaries’ ability to

S-24

incur additional indebtedness, issue or repurchase securities, pay dividends or engage in transactions with affiliates. We, therefore, may pay dividends, incur additional debt, including secured indebtedness in certain circumstances or indebtedness by, or other obligations of, our subsidiaries to which the Notes would be structurally subordinated, repurchase securities, engage in transactions with affiliates or engage in other activities, which would adversely affect our ability to pay our obligations under the Notes. Our ability to incur additional indebtedness and use our funds for numerous purposes may limit the funds available to pay our obligations under the Notes. See “Description of the Notes—Certain Covenants.”

If (x) the consummation of the Adenza Transaction does not occur on or before the later of (i) the date that is five (5) business days after September 10, 2024 and (ii) the date that is five (5) business days after any later date to which Seller and we may agree to extend the “Outside Date” in the Adenza Transaction Agreement or (y) we notify the Trustee that we will not pursue the consummation of the Adenza Transaction, we will be required to redeem the Notes and may not have or be able to obtain all the funds necessary to redeem the Notes. In addition, if we are required to redeem the Notes, you may not obtain your expected return on the Notes.

We may not be able to consummate the Adenza Transaction within the timeframe specified under “Description of the Notes—Redemption—Special Mandatory Redemption.” Our ability to consummate the Adenza Transaction is subject to various closing conditions, many of which are beyond our control, and we may not be able to consummate the Adenza Transaction. If (x) the consummation of the Adenza Transaction (as defined herein) does not occur on or before the later of (i) the date that is five (5) business days after September 10, 2024 and (ii) the date that is five (5) business days after any later date to which Seller and we may agree to extend the “Outside Date” in the Adenza Transaction Agreement or (y) we notify the Trustee that we will not pursue the consummation of the Adenza Transaction, we will be required to redeem all Notes at a redemption price equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the special mandatory redemption date. However, there is no escrow account or security interest for the benefit of the noteholders and it is possible that we will not have sufficient financial resources available to satisfy our obligations to redeem the Notes. This could be the case, for example, if we or any of our subsidiaries commence a bankruptcy or reorganization case, or such a case is commenced against us or one of our subsidiaries, before we redeem the Notes. In addition, even if we are able to redeem the Notes pursuant to the special mandatory redemption provisions you may not obtain your expected return on the Notes and may not be able to reinvest the proceeds from a special mandatory redemption in an investment that results in a comparable return. Your decision to invest in the Notes is made at the time of the offering of the Notes. You will have no rights under the special mandatory redemption provisions as long as the Adenza Transaction is consummated on or prior to the later of (i) the date that is five (5) business days after September 10, 2024 and (ii) the date that is five (5) business days after any later date to which Seller and we may agree to extend the “Outside Date” in the Adenza Transaction Agreement nor will you have any right to require us to repurchase your Notes if, between the closing of the Notes offering and the closing of the Adenza Transaction, we experience any changes in our business or financial condition, or if the terms of the Adenza Transaction or the financing thereof change.

We may not be able to repurchase the Notes upon a change of control triggering event.

Unless we have exercised our right to redeem the Notes as described in the indenture, upon a change of control triggering event, we will be required to make an offer to each holder of the Notes to repurchase all or any part of such holder’s Notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase. A “change of control triggering event” will occur when there is (i) a change of control involving Nasdaq and (ii) within a specified period in relation to the change of control, the ratings of the Notes are decreased from an

S-25

investment grade rating by each of Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services to below an investment grade rating by each of Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services. If we experience a change of control triggering event, there can be no assurance that we will have sufficient financial resources available at such time to satisfy our obligations to repurchase the Notes. Our failure to purchase the Notes as required under the indenture governing the Notes would result in a default under the indenture, which could have material adverse consequences for us and the holders of the Notes. See “Description of the Notes—Repurchase upon Change of Control Triggering Event.”

Holders of the Notes may be subject to the effects of foreign currency exchange rate fluctuations, as well as possible exchange controls, relating to the euro.

Investors will have to pay for the Notes in euro. Payments of principal, interest and Additional Amounts, if any, in respect of the Notes are payable by us in euro. An investment in the Notes which are denominated in, and all payments in respect of which are to be made in, a currency other than the currency of the country in which the purchaser is resident or the currency in which the purchaser conducts its business activities (the “home currency”) entails significant risks not associated with a similar investment in a security denominated in the home currency.

These include the possibility of:

We have no control over a number of factors affecting notes denominated in a currency other than an investor’s home currency, including economic, financial and political events that are important in determining the existence, magnitude and longevity of these risks and their results. In recent years, rates of exchange for certain currencies, including the euro, have been highly volatile and this volatility may continue in the future.

Despite measures taken to alleviate credit risk, concerns persist regarding the debt burden of certain member states of the European Monetary Union and their ability to meet future financial obligations, the overall stability of the euro and the suitability of the euro as a single currency given the diverse economic and political circumstances in individual member states. These and other concerns could lead to the reintroduction of individual currencies in one or more member states, or, in more extreme circumstances, the possible dissolution of the euro entirely. Should the euro dissolve entirely, the legal and contractual consequences for holders of euro-denominated obligations would be determined by laws in effect at such time. The official exchange rate at which the Notes may be redenominated may not accurately reflect their value in euro. These potential developments, or market perceptions concerning these developments and related issues, could adversely affect the value of the Notes.

Fluctuations in any particular exchange rate that have occurred in the past are not necessarily indicative of fluctuations in the rate that may occur during the term of the Notes. Depreciation of the euro against the home currency could result in a decrease in the effective yield of the Notes below the coupon rate, in the investor’s home currency equivalent of the principal payable at the maturity of the Notes and generally in the investor’s home currency equivalent market value of the Notes. Appreciation of the euro in relation to the investor’s home currency would have the opposite effect.

The United Kingdom, the European Union or one or more of its member states may, in the future, impose exchange controls and modify any exchange controls imposed, which controls could affect

S-26

exchange rates as well as the availability of the euro at the time of payment of principal of, interest on, or any redemption payment or Additional Amounts with respect to, the Notes.

This description of foreign currency risks does not describe all the risks of an investment in securities denominated in a currency other than an investor’s home currency. You should consult your own financial and legal advisors as to the risks involved in an investment in the Notes.

On June     , 2023, the closing euro/U.S. dollar rate of exchange was U.S. $             per €1.00, as reported by Bloomberg L.P.

The Notes permit us to make payments in U.S. dollars if we are unable to obtain euro.

If the euro is unavailable due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then in such circumstances, all payments in respect of the Notes will be made in U.S. dollars until the euro is again available to us or so used. The amount payable on any date in euro will be converted into U.S. dollars on the basis of the then most recently available market exchange rate for euro as determined by us in our sole discretion. There can be no assurance that this exchange rate will be as favorable to holders of notes as the exchange rate otherwise determined by applicable law. These potential developments, or market perceptions concerning these and related issues, could adversely affect the value of the notes. Any payment in respect of the Notes so made in U.S. dollars will not constitute an event of default under the Notes or the indenture governing the Notes. See “Description of the Notes—Euro Notes—Issuance in Euros”.

In a lawsuit for payment on the notes, an investor may bear currency exchange risk.

The indenture is, and the Notes will be, governed by the laws of the State of New York. Under New York law, a New York state court rendering a judgment on the Notes would be required to render the judgment in euros. However, the judgment would be converted into U.S. dollars at the market exchange rate prevailing on the date of entry of the judgment. Consequently, in a lawsuit for payment on the Notes, investors would bear currency exchange risk until a New York state court judgment is entered, which could be a significant amount of time. A federal court sitting in New York with diversity jurisdiction over a dispute arising in connection with the Notes would apply New York law. In courts outside of New York, investors may not be able to obtain a judgment in a currency other than U.S. dollars. For example, a judgment for money in an action based on the notes in many other U.S. federal or state courts ordinarily would be enforced in the United States only in U.S. dollars. The date used to determine the rate of conversion of euros into U.S. dollars would depend upon various factors, including which court renders the judgment and when the judgment is rendered.

Trading in the clearing systems is subject to minimum denomination requirements.

The Notes will be issued only in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. It is possible that the clearing systems may process trades which could result in amounts being held in denominations smaller than the minimum denominations. If definitive notes are required to be issued in relation to such Notes in accordance with the provisions of the relevant global notes, a holder who does not have the minimum denomination or an integral multiple of €1,000 in excess thereof in its account with the relevant clearing system at the relevant time may not receive all of its entitlement in the form of definitive notes unless and until such time as its holding satisfies the minimum denomination requirement.

S-27

USE OF PROCEEDS

The net proceeds from the offering of the Notes, after deducting the underwriting discount and our estimated offering expenses, will be approximately €            . We expect to use the net proceeds from the offering of the Notes, together with cash on hand and proceeds of other incurrences of indebtedness (which may include, among other things, commercial paper, the Bridge Facility or replacements thereof, including the new term loan facility and/or the Dollar Offering), to fund the cash consideration payable by us pursuant to the Adenza Transaction Agreement, to repay certain outstanding indebtedness of Adenza and its subsidiaries and to pay related fees and expenses in connection with the Adenza Transaction and for general corporate purposes, which may include, without limitation, the repayment of indebtedness or the funding of other future acquisitions.

DESCRIPTION OF THE NOTES

The                 % Senior Notes due 20         (the “Notes”) offered hereby will be issued under an indenture, dated as of June 7, 2013 (the “base indenture”) between Nasdaq, Inc. and Computershare Trust Company, N.A., as trustee (as successor to Wells Fargo Bank, National Association, the “Trustee”) and an eighteenth supplemental indenture, to be dated as of June    , 2023 (together with the base indenture, the “indenture”). In this Description of the Notes section, “we,” “us,” “our,” “Nasdaq” or the “Company” and similar words refer to Nasdaq, Inc. and not to any of its subsidiaries.

Because this section is a summary, it does not describe every aspect of the Notes and the indenture. This summary is subject to, and qualified in its entirety by reference to, all the provisions of the Notes and the indenture, including definitions of certain terms used therein. The terms of the Notes will include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended, or the “TIA.” You may obtain copies of the Notes and the indenture by requesting them from us or the Trustee.

General

The Notes:

Principal, Maturity and Interest of Notes

The Notes will initially be limited to €             million aggregate principal amount. The Notes will be issued in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof.

The Notes will bear interest at a rate of    % per year. Interest on the Notes will be payable annually in arrears on                of each year, beginning on                , 20    , and will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or the settlement date if no interest has been paid or duly provided for on the Notes), to but excluding the next date on which interest is paid or duly provided for. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association. Interest on the Notes will accrue from and including the settlement date and will be paid to holders of record on the day immediately prior to the applicable interest payment date.

The Notes will mature on , 20 . On the maturity date of the Notes, the holders will be entitled to receive 100% of the principal amount of such Notes. The Notes will not have the benefit of any sinking fund.

S-29

If any interest payment date, redemption date or maturity date falls on a day that is not a business day, then the relevant payment may be made on the next succeeding business day and no interest will accrue because of such delayed payment. With respect to the Notes, when we use the term “business day” we mean any day except a Saturday, a Sunday or a day on which banking institutions in the applicable place of payment are authorized or required by law, regulation or executive order to close.

Claims against the Company for payment of principal, interest and Additional Amounts (as defined below), if any, on the Notes will become void unless presentment for payment is made (where so required under the indenture) within, in the case of principal and Additional Amounts, if any, a period of ten years or, in the case of interest, a period of five years, in each case from the applicable original date of payment therefor.

Euro Notes—Issuance in Euros

Initial holders of the Notes will be required to pay for the Notes in euros, and principal, premium, if any, and interest payments and additional amounts, if any, in respect of the Notes will be payable in euros.

If, on or after the date of this prospectus supplement, the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or the euro is no longer used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions within the international banking community, then all payments in respect of the Notes will be made in U.S. dollars until the euro is again available to us or so used. The amount payable on any date in euros will be converted to U.S. dollars on the basis of the most recently available market exchange rate for euros as determined by us in our sole discretion. Any payment in respect of the Notes so made in U.S. dollars will not constitute an event of default under the indenture or the Notes. Neither the Trustee nor the paying agent will be responsible for obtaining exchange rates, effecting conversions or otherwise handling redenominations.

Priority

The Notes will be general unsecured obligations of ours and will rank equally in right of payment with all of our existing and future unsubordinated unsecured obligations.

Holders of any secured indebtedness and other secured obligations of the Company will have claims that are prior to your claims as holders of the Notes, to the extent of the value of the assets securing such indebtedness and other obligations, in the event of any bankruptcy, liquidation or similar proceeding.

As of December 31, 2022, after giving effect to this offering and incurrences of debt under the Bridge Facility or anticipated replacements thereof and any other debt incurred to finance the Adenza Transaction, we would have had approximately $11.0 billion aggregate principal amount of unsubordinated unsecured indebtedness outstanding and no material secured indebtedness or other secured obligations outstanding.

We conduct our operations through subsidiaries. As a result, distributions or advances from our subsidiaries are a major source of funds necessary to meet our debt service and other obligations. Contractual provisions, laws or regulations, as well as our subsidiaries’ financial condition and operating requirements, may limit our ability to obtain cash required to pay our debt service obligations, including payments on the Notes. The Notes will not be guaranteed by any of our subsidiaries, and will therefore

S-30

be “structurally” subordinated to all indebtedness and other obligations of our subsidiaries, including claims with respect to trade payables, which may be material. This means that in the event of bankruptcy, liquidation or reorganization of any of our subsidiaries, the holders of Notes will have no direct claim to participate in the assets of such subsidiary but may only recover by virtue of our equity interest in our subsidiaries (except to the extent we have a claim as a creditor of such subsidiary). Holders of all existing and future indebtedness and other liabilities of our subsidiaries, including trade payables and claims of lessors under leases, have the right to be satisfied in full prior to our receipt of any payment as any equity owner of our subsidiaries. As of December 31, 2022, after giving effect to this offering and incurrences of debt under the Bridge Facility or anticipated replacements thereof and any other debt incurred to finance the Adenza Transaction, our direct and indirect subsidiaries would have had approximately no indebtedness outstanding to which the Notes would have been structurally subordinated.

Further Issues

The Notes will constitute a separate series of debt securities under the indenture, initially limited to €                . Under the indenture, we may, without the consent of the holders of the Notes, issue additional notes of the same or a different series from time to time in the future in an unlimited aggregate principal amount; provided that if any such additional notes are not fungible with the Notes offered hereby (or any other tranche of additional notes) for U.S. federal income tax purposes, then such additional notes will have different ISIN and/or Common Code numbers than the Notes offered hereby (and any such other tranche of additional notes, as applicable). The Notes offered hereby and any additional notes of the same series would rank equally and ratably and would be treated as a single class for all purposes under the indenture. This means that, in circumstances where the indenture provides for the holders of debt securities of any series to vote or take any action, any of the outstanding Notes, as well as any additional notes that we may issue by reopening such series, will vote or take action as a single class.

Payment of Additional Amounts by a Foreign Successor Issuer

A Foreign Successor Issuer is any entity that is organized in a jurisdiction other than the United States, any state thereof or the District of Columbia and becomes a successor of Nasdaq, Inc. as a result of a merger of Nasdaq, Inc. with and into such entity after the date hereof in accordance with the provisions set forth in “Certain Covenants—Merger, Consolidation or Sale of Assets.”

All payments made under or with respect to the Notes by any Foreign Successor Issuer will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including, without limitation, penalties, interest and other similar liabilities related thereto) of whatever nature (collectively, “Taxes”) imposed or levied by or on behalf of any jurisdiction in which such Foreign Successor Issuer is organized, resident or doing business for tax purposes or from or through which such Foreign Successor Issuer makes any payment on the Notes, in each case, or any department or political subdivision thereof (each, a “Relevant Taxing Jurisdiction”), unless such Foreign Successor Issuer or any other applicable withholding agent is required to withhold or deduct Taxes by law. For the avoidance of doubt a Relevant Taxing Jurisdiction shall not include the United States, any state thereof or the District of Columbia. If a Foreign Successor Issuer or any other applicable withholding agent is required by law to make any such withholding or deduction, the Foreign Successor Issuer, subject to the exceptions listed below, will pay such additional amounts (“Additional Amounts”) as may be necessary to ensure that the net amount received by each beneficial owner of the Notes after such withholding or deduction (including withholding or deduction attributable to Additional Amounts payable hereunder) will not be less than the amount the beneficial owner would have received if such Taxes had not been withheld or deducted (provided that if the applicable withholding agent is a person other

S-31

than a Foreign Successor Issuer, the Additional Amounts payable by the Foreign Successor Issuer under “—Payment of Additional Amounts by a Foreign Successor Issuer” shall not exceed the Additional Amounts that would have been payable by the Foreign Successor Issuer under “—Payment of Additional Amounts by a Foreign Successor Issuer” had the Foreign Successor Issuer been the applicable withholding agent (i.e., had the Foreign Successor Issuer made payments directly to the applicable beneficial owner of the Notes)).

A Foreign Successor Issuer will not, however, pay Additional Amounts to a holder or beneficial owner of Notes:

S-32

A Foreign Successor Issuer will (i) make any such withholding or deduction required by applicable law and (ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Foreign Successor Issuer will make reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Relevant Taxing Jurisdiction imposing such Taxes and the Foreign Successor Issuer will provide to the Trustee, within a reasonable time after the date the payment of any Taxes so deducted or withheld are due pursuant to applicable law, either a certified copy of tax receipts evidencing such payment, or, if such tax receipts are not reasonably available to the Foreign Successor Issuer, such other documentation that provides reasonable evidence of such payment by the Foreign Successor Issuer.

At least 30 calendar days prior to each date on which any payment under or with respect to the Notes is due and payable, if the Foreign Successor Issuer will be obligated to pay Additional Amounts with respect to such payment (unless such obligation to pay Additional Amounts arises after the 35th day prior to the date on which payment under or with respect to the Notes is due and payable, in which case it will be promptly thereafter), the Foreign Successor Issuer will deliver to the Trustee an officers’ certificate stating that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the Trustee to pay such Additional Amounts to holders on the payment date. The Foreign Successor Issuer will promptly publish a notice in accordance with the provisions set forth in “—Notices” stating that such Additional Amounts will be payable and describing the obligation to pay such amounts.

In addition, a Foreign Successor Issuer will pay any stamp, issue, registration, court, documentation, excise or other similar taxes, charges and duties, including interest, penalties and other similar liabilities with respect thereto, imposed by any Relevant Taxing Jurisdiction at any time after the merger described above in respect of the execution, issuance, registration or delivery of the Notes or any other document or instrument referred to thereunder and any such taxes, charges or duties imposed by any Relevant Taxing Jurisdiction at any time after the merger described above as a result of, or in connection with, any payments made pursuant to the Notes and/or the enforcement of the Notes and/or any other such document or instrument.

The obligations described under this heading will survive any termination, defeasance or discharge of the indenture and will apply mutatis mutandis to any successor Person to any Foreign Successor Issuer (other than a Person organized under the laws of the United States, any state thereof or the District of Columbia) and to any jurisdiction in which such successor is organized, resident or doing business for tax purposes or any jurisdiction from or through which payment is made by such successor or its respective agents, or, in each case, any department or political subdivision thereof.

Whenever the applicable indenture or this “Description of the Notes” refers to, in any context, the payment of principal, premium, if any, interest or any other amount payable under or with respect to any Note, such reference includes the payment of Additional Amounts as described hereunder, if applicable.

Redemption

Optional Redemption

The Notes will be redeemable, in whole, at any time, or in part, from time to time, at our option, prior to                 , 20    (the “Par Call Date”) at a redemption price (the “make-whole redemption price”) equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed and (ii) as determined by the Quotation Agent (as defined below), the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (assuming the Notes matured on the Par Call Date and exclusive of interest accrued and unpaid as of the date of

S-33

redemption), discounted to the date of redemption on an annual basis (ACTUAL/ACTUAL (ICMA)) at the Bund Rate (as defined below), plus                basis points, plus accrued and unpaid interest thereon to the date of redemption. However, if the redemption date is after a record date and on or prior to a corresponding interest payment date, the interest will be paid on the redemption date to the holder of record on the record date.

Notwithstanding the foregoing, at any time on or after the Par Call Date, the Notes will be redeemable, in whole at any time, or in part, from time to time, at our option, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the date of redemption.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days, but not more than 60 days, before the redemption date to each registered holder of Notes to be redeemed. Any notice of redemption may, at our discretion, be subject to one or more conditions precedent, including, but not limited to, completion of securities offerings or other corporate transactions. Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes (or portion thereof) to be redeemed on such redemption date.

“Bund Rate” means, with respect to any redemption date, the rate per annum equal to the annual equivalent yield to maturity of the Comparable German Bund Issue, assuming a price for the Comparable German Bund Issue (expressed as a percentage of its principal amount) equal to the Comparable German Bund Price for such redemption date.

“Comparable German Bund Issue” means that German Bundesanleihe security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate notes of comparable maturity to the remaining term of the Notes.

“Comparable German Bund Price” means, with respect to any redemption date, (i) the average of four Reference German Bund Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference German Bund Dealer Quotations or (ii) if the Quotation Agent obtains fewer than four such Reference German Bund Dealer Quotations, the average of all such quotations.

“Quotation Agent” means a Reference German Bund Dealer appointed by us.

“Reference German Bund Dealer” means any dealer of German Bundesanleihe securities selected by us in good faith.

“Reference German Bund Dealer Quotations” means, with respect to each Reference German Bund Dealer and any redemption date, the average, as determined by us, of the bid and asked prices for the Comparable German Bund Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference German Bund Dealer at 3:30 p.m., Frankfurt, Germany time, on the third business day preceding such redemption date.

If we elect to redeem less than all of the Notes, and such Notes are at the time represented by a global note, then the Trustee will select pro rata or by lot or by a method the Trustee deems to be fair and appropriate, in accordance with the depositary’s procedures, the particular interests to be redeemed. If we elect to redeem less than all of the Notes, and any of such Notes are not represented by a global note, then the Trustee will select the particular Notes to be redeemed in a manner it deems appropriate and fair (and the depositary will select by lot the particular interests in any global note to be redeemed).

S-34

We may at any time, and from time to time, purchase the Notes at any price or prices in the open market or otherwise.

Special Mandatory Redemption

If (x) the consummation of the Adenza Transaction does not occur on or before the later of (i) the date that is five (5) business days after September 10, 2024 and (ii) the date that is five (5) business days after any later date to which Seller and we may agree to extend the “Outside Date” in the Adenza Transaction Agreement (such later date, the “Extended Termination Date”) or (y) we notify the Trustee that we will not pursue the consummation of the Adenza Transaction (the earlier of the date of delivery of such notice described in clause (y) and the Extended Termination Date, the “special mandatory redemption trigger date”), we will be required to redeem all and not less than all of the Notes then outstanding by a date no later than 10 business days after the special mandatory redemption trigger date (the “special mandatory redemption end date”) at a redemption price equal to 101% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the special mandatory redemption date (the “special mandatory redemption price”).

In the event that we become obligated to redeem the Notes pursuant to the foregoing paragraph, we will promptly, and in any event not more than five business days after the special mandatory redemption trigger date, deliver notice to the Trustee of the special mandatory redemption and the date upon which the Notes will be redeemed (the “special mandatory redemption date,” which date shall be no later than the special mandatory redemption end date). The Trustee will then promptly deliver such notice to each holder of Notes at its registered address. Unless we default in payment of the special mandatory redemption price, on and after such special mandatory redemption date, interest will cease to accrue on the Notes and the indenture will be discharged and cease to be of further effect as to all Notes.

“Adenza Transaction” means the Company’s acquisition of Adenza.

“Adenza Transaction Agreement” means that certain Agreement and Plan of Merger, dated as of June 10, 2023, among the Company, Argus Merger Sub 1, Inc., Argus Merger Sub 2, LLC, Adenza Holdings, Inc. (“Adenza”) and Adenza Parent, LP (“Seller”).

Tax Redemption

If, as a result of:

such Foreign Successor Issuer would be obligated to pay, on the next date for any payment, Additional Amounts as described above under “—Payment of Additional Amounts by a Foreign Successor Issuer” with respect to the Relevant Taxing Jurisdiction, which such Foreign Successor

S-35

Issuer reasonably determines it cannot avoid by the use of reasonable measures available to it, then such Foreign Successor Issuer may redeem all, but not less than all, of the Notes, at any time thereafter, upon not less than 30 nor more than 60 days’ notice, at a redemption price of 100% of their principal amount, plus accrued and unpaid interest, if any, to the redemption date. Prior to the giving of any notice of redemption described in this paragraph, a Foreign Successor Issuer will deliver to the Trustee:

A Foreign Successor Issuer will deliver a notice of any optional redemption of the Notes described above to each registered holder of the Notes in accordance with the provisions of the indenture described under “—Notices.” No such notice of redemption may be given more than 60 days before or 365 days after the Foreign Successor Issuer first becomes liable to pay any Additional Amounts.

Repurchase upon Change of Control Triggering Event

If a Change of Control Triggering Event (as defined below) occurs with respect to the Notes, unless we have exercised our right to redeem the Notes as described under “—Optional Redemption,” “—Special Mandatory Redemption” or “—Tax Redemption,” we will be required to make an offer to repurchase all or, at the holder’s option, any part (equal to €100,000 or any integral multiple of €1,000 in excess thereof) of each holder’s Notes pursuant to the offer described below (the “Change of Control Offer”).

In the Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of purchase (the “Change of Control Payment”).

Within 30 days following any Change of Control Triggering Event with respect to the Notes or, at our option, prior to any Change of Control (as defined below) but after the public announcement of the transaction or transactions that constitutes or may constitute a Change of Control, we will be required to mail a notice to holders of the Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date will be no earlier than 30 and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by such Notes and described in such notice. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. We will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of such Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes or the indenture, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the Notes or the indenture by virtue of such conflict.

S-36

On the Change of Control Payment Date, we will be required, to the extent lawful, to:

The paying agent for the Notes will be required to promptly mail, to each holder who properly tendered Notes, the purchase price for such Notes, and the Trustee will be required to promptly authenticate and mail (or cause to be transferred by book entry) to each such holder a new note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new note will be in a principal amount of €100,000 or an integral multiple of €1,000 in excess thereof.

We will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all Notes properly tendered and not withdrawn under its offer. In the event that such third party terminates or defaults on its offer, we will be required to make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event. In addition, we will not purchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the indenture, other than a default in the payment of the Change of Control Payment.

“Below Investment Grade Rating Event” with respect to the Notes means the ratings of the Notes are decreased from an Investment Grade Rating by each of the Rating Agencies to below an Investment Grade Rating by each of the Rating Agencies on any date during the period commencing upon the first public notice of the occurrence of a Change of Control or our intention to effect a Change of Control and ending 60 days following public notice of the occurrence of the related Change of Control (which 60-day period shall be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of “Change of Control Triggering Event” hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the holders of the Notes in writing at their request that the reduction was the result, in whole or in part, of any event or circumstance comprising or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the occurrence of any of the following: (1) the direct or indirect sale, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of us and our Subsidiaries taken as a whole to any Person or group of related Persons for purposes of Section 13(d) of the Exchange Act (a “Group”) other than us or one of our Subsidiaries; (2) the approval by the holders of our common stock of any plan or proposal for our liquidation or dissolution; (3) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any Person or Group becomes the beneficial owner, directly or indirectly, of more than 50% of the then outstanding number of shares of our Voting Stock; or (4) the first day on which a majority of the members of our board of directors are not Continuing Directors.

S-37

Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control if (1) we become a direct or indirect wholly owned Subsidiary of a holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of our Voting Stock immediately prior to that transaction or (B) immediately following that transaction no Person or Group (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event occurring in respect of that Change of Control.

“Continuing Directors” means, as of any date of determination, any member of our board of directors who (1) was a member of our board of directors on the date of the issuance of the Notes; or (2) was nominated or approved for election, elected or appointed to our board of directors with the approval of a majority of the Continuing Directors who were members of our board of directors at the time of such nomination, approval, election or appointment (either by a specific vote or by approval of the proxy statement issued by us in which such member was named as a nominee for election as a director). “Investment Grade Rating” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s and BBB- (or the equivalent) by S&P or the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by us.

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors.

“Person” means any individual, firm, limited liability company, corporation, partnership, association, joint venture, tribunal, trust, government or political subdivision or agency or instrumentality thereof, or any other entity or organization and includes a “person” as used in Section 13(d)(3) of the Exchange Act.

“Rating Agencies” means (1) each of Moody’s and S&P; and (2) if any of Moody’s or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” within the meaning of Section 3(a) (62) of the Exchange Act, that we select (as certified by an executive officer of ours) as a replacement agency for Moody’s or S&P, or both of them, as the case may be.

“S&P” means S&P Global Ratings Services (a division of S&P Global Inc.) or any successor to the rating agency business thereof.

“Voting Stock” of any specified Person as of any date means the capital stock of such Person that is at the time entitled to vote generally in the election of the board of directors of such Person.

The definition of “Change of Control” and the merger, consolidation or sale of assets covenant each include a phrase relating to the sale, transfer, conveyance or other disposition of “all or substantially all” of our consolidated assets. There is no precise, established definition of the phrase “substantially all” under applicable law. Accordingly, your ability to require us to purchase your Notes, or whether the merger, consolidation or sale of assets covenant would apply to a particular transaction, as a result of the sale, transfer, conveyance or other disposition of less than all of our assets may be uncertain.

S-38

Certain Covenants

The indenture will contain, among others, the following covenants:

“Indebtedness” means any indebtedness (whether being principal, premium, interest or other amounts) for or in respect of any notes, bonds, debentures or other instruments for money borrowed or any borrowed money or any liability under or in respect of any banker’s acceptance (other than a daylight overdraft).

With respect to any Sale and Lease-Back Transaction (as defined below) or series of related Sale and Lease-Back Transactions, the determination of whether any property is a Principal Property shall be determined by reference to all properties affected by such transaction or series of transactions.

Limitations on Sale and Lease-Back Transactions

We will not, nor will we permit any of our Significant Subsidiaries to, enter into any Sale and Lease-Back Transaction (as defined below) with respect to any Principal Property, other than (x) any such Sale and Lease-Back Transaction involving a lease for a term of not more than three years or (y) any such Sale and Lease-Back Transaction between us and one of our Subsidiaries or between our Subsidiaries, unless: (a) we or such Significant Subsidiary would be entitled to incur Indebtedness secured by a lien on the Principal Property involved in such Sale and Lease-Back Transaction at least equal in amount to the Attributable Debt (as defined below) with respect to such Sale and Lease-Back Transaction, without equally and ratably securing the Notes, pursuant to the covenant described above under the caption “—Limitations on Liens”; or (b) the proceeds of such Sale and Lease-Back Transaction are at least equal to the fair market value of the affected Principal Property (as determined in good faith by our board of directors) and we apply an amount equal to the net proceeds of such Sale and Lease-Back Transaction within 365 days of such Sale and Lease-Back Transaction to any (or a

combination) of (i) the prepayment or retirement of the Notes, (ii) the prepayment or retirement (other than any mandatory retirement, mandatory prepayment or sinking fund payment or by payment at maturity) of other Indebtedness of us or of one of our Subsidiaries (other than Indebtedness that is subordinated to the Notes or Indebtedness owed to us or one of our Subsidiaries) that matures more than 12 months after its creation (including any such Indebtedness that by its terms is renewable or extendible beyond 12 months from the date of its creation, at the option of the borrower) or (iii) the purchase, construction, development, expansion or improvement of other comparable property.

“Attributable Debt” with regard to a Sale and Lease-Back Transaction with respect to any Principal Property means, at the time of determination, the present value of the total net amount of rent required to be paid under such lease during the remaining term thereof (including any period for which such lease has been extended), discounted at the rate of interest set forth or implicit in the terms of such lease (or, if not practicable to determine such rate, the weighted average interest rate per annum borne by the securities of all series then outstanding under the indenture) compounded semi-annually. In the case of any lease which is terminable by the lessee upon the payment of a penalty, such net amount shall be the lesser of (x) the net amount determined assuming termination upon the first date such lease may be terminated (in which case the net amount shall also include the amount of the penalty, but shall not include any rent that would be required to be paid under such lease subsequent to the first date upon which it may be so terminated) or (y) the net amount determined assuming no such termination.

“Sale and Lease-Back Transaction” means any arrangement with any person providing for the leasing by us or any of our Significant Subsidiaries of any Principal Property, whether now owned or hereafter acquired, which Principal Property has been or is to be sold or transferred by us or such Significant Subsidiary to such person.

Excepted Indebtedness

Notwithstanding the limitations on Liens and Sale and Lease-Back Transactions described above, and without limiting our or any Significant Subsidiary’s ability to issue, incur, create, assume or guarantee Indebtedness secured by Permitted Liens, we and any Significant Subsidiary will be permitted to incur Indebtedness secured by a Lien or may enter into a Sale and Lease-Back Transaction, in either case, without regard to the restrictions contained in the preceding two sections entitled “Certain Covenants—Limitations on Liens” and “Certain Covenants—Limitations on Sale and Lease-Back Transactions,” if at the time the Indebtedness is incurred and after giving effect to this Indebtedness and to the retirement of Indebtedness which is being retired substantially concurrently therewith, the sum of (a) the aggregate principal amount of all Indebtedness secured by Subject Liens other than Permitted Liens and (b) the Attributable Debt of all our Sale and Lease-Back Transactions not otherwise permitted by the provisions described under “Certain Covenants—Limitations on Sale and Lease-Back Transactions,” does not exceed 15% of Consolidated Net Tangible Assets (as defined below).

“Consolidated Net Tangible Assets” means, at any date, the aggregate amount of assets (less applicable reserves) of the Company and its Subsidiaries after deducting therefrom (a) all goodwill, tradenames, trademarks, patents, unamortized debt discount and expense and other like intangibles and (b) all current liabilities (excluding any current liabilities for money borrowed having a maturity of less than 12 months but by its terms is renewable or extendible beyond 12 months from such date at the option of the borrower), all as reflected in the Company’s most recent consolidated balance sheet as at the end of its fiscal quarter ending not more than 135 days prior to such date, prepared in accordance with United States generally accepted accounting principles.

Events of Default

Holders of the Notes will have specified rights if an Event of Default (as defined below) occurs.

The term “Event of Default” in respect of the Notes means any of the following:

If an Event of Default (other than an Event of Default specified in clause (5) above) with respect to the Notes has occurred, the Trustee or the holders of at least 25% in principal amount of the Notes may declare the entire unpaid principal amount of (and premium, if any), and all the accrued interest on, the Notes to be due and immediately payable. This is called a declaration of acceleration of maturity. There is no action on the part of the Trustee or any holder of the Notes required for such declaration if the Event of Default is the Company’s bankruptcy, insolvency or reorganization. Holders of a majority in principal amount of the Notes may also waive certain past defaults under the indenture with respect to the Notes on behalf of all of the holders of the Notes. A declaration of acceleration of maturity may be canceled, under specified circumstances, by the holders of at least a majority in principal amount of the Notes and the Trustee.

Except in cases of default, where the Trustee has special duties, the Trustee is not required to take any action under the indenture at the request of holders unless the holders offer the Trustee protection from expenses and liability satisfactory to the Trustee. If an indemnity satisfactory to the Trustee is provided, the holders of a majority in principal amount of Notes may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the Trustee. The Trustee may refuse to follow those directions in certain circumstances specified in the indenture. No delay or omission in exercising any right or remedy will be treated as a waiver of the right, remedy or Event of Default.

S-43

Before holders of the Notes are allowed to bypass the Trustee and bring a lawsuit or other formal legal action or take other steps to enforce their rights or protect their interests relating to the Notes, the following must occur:

Holders are, however, entitled at any time to bring a lawsuit for the payment of money due on the Notes on or after the due date.

Modification of the Indenture and Waiver of Rights of Holders

Under certain circumstances, we can make changes to the indenture and the Notes. Some types of changes require the approval of each holder of Notes, some require approval by a vote of a majority of the holders of the Notes, and some changes do not require any approval at all.

Changes Requiring Approval of All Holders

First, there are changes that cannot be made to the Notes without the approval of holders of all Notes. These include changes that:
