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:

• our operating results may be lower than expected;

• our ability to successfully integrate acquired businesses or divest sold businesses or assets, including the fact that any integration or transition may be more difficult, time consuming or costly than expected, and we may be unable to realize synergies from business combinations, acquisitions, divestitures or other transactional activities;

• loss of significant trading and clearing volumes or values, fees, market share, listed companies, market data customers or other customers;

• our ability to develop and grow our non-trading businesses;

• our ability to keep up with rapid technological advances, including our ability to effectively manage the development and use of artificial intelligence in certain of our products and offerings, and adequately address cybersecurity risks;

S-3

• the performance and reliability of our technology and technology of third parties on which we rely;

• any significant systems failures or errors in our operational processes;

• our ability to continue to generate cash and manage our indebtedness; and

• adverse changes that may occur in the litigation or regulatory areas, or in the securities markets generally, or increased regulatory oversight domestically or internationally.

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.

You should read the following summary together with the more detailed information and consolidated financial statements and the notes to those statements included elsewhere in this prospectus supplement and the accompanying prospectus and incorporated by reference herein.

Nasdaq, Inc.

Nasdaq is a global technology company serving corporate clients, investment managers, banks, brokers, and exchange operators as they navigate and interact with the global capital markets and the broader financial system. We aspire to deliver world-leading platforms that improve the liquidity, transparency, and integrity of the global economy. Our diverse offering of data, analytics, software, exchange capabilities, and client-centric services enables clients to optimize and execute their business vision with confidence.

We manage, operate and provide our products and services in three business segments: Capital Access Platforms, Financial Technology and Market Services.

Capital Access Platforms

Our Capital Access Platforms segment delivers liquidity, transparency and integrity to the corporate issuer and investment community by empowering our clients to effectively navigate the capital markets, achieve their sustainability goals, and drive governance excellence. We offer a suite of products to assist companies in managing corporate governance standards.

Our Capital Access Platforms segment includes Data & Listing Services, Index and Workflow & Insights.

Data & Listing Services

Our North American and European data products enhance transparency of market activity within our exchanges and provide critical information to professional and non-professional investors globally. Our Data business distributes historical and real-time market data to sell-side customers, the institutional investing community, retail online brokers, proprietary trading firms, and other venues, as well as internet portals and data distributors.

We collect, process, and create information and earn revenues as a distributor of our own, as well as select third-party, content. We provide varying levels of quote and trade information to market participants and to data distributors who in turn provide subscriptions for this information. Our systems enable distributors to gain access to our market depth, fund valuation, order imbalances, market sentiment and other analytical data.

We distribute this proprietary market information to both market participants and non-participants through a number of proprietary products, including Nasdaq TotalView, our flagship market depth quote product. We offer TotalView products for The Nasdaq Stock Market and our Nasdaq BX, Nasdaq PSX and Nordic markets.

Additionally, our Nasdaq Cloud Data Service provides a flexible and efficient method of delivery for real-time exchange data and other financial information. Data is made available through a suite of application programming interfaces, or APIs, allowing for the integration of data from disparate sources and a reduction in time to market for customer-designed applications. These APIs are highly scalable and can support the delivery of real-time exchange data.

We operate a variety of listing platforms around the world to provide multiple global capital raising solutions for public companies. Companies listed on our markets represent a diverse array of industries including, among others, healthcare, consumer products, telecommunication services, information technology, financial services, industrials and energy.

Companies seeking to list securities on The Nasdaq Stock Market may do so on one of the three market tiers: The Nasdaq Global Select Market, The Nasdaq Global Market, or The Nasdaq Capital Market.

Recent Developments

Cash Dividend to Holders of Common Stock

Certain Business and Financial Information Used by the Company

Nasdaq presents certain financial information, which includes non-GAAP measures, including, but not limited to, organic revenue growth, non-GAAP EBITDA, non-GAAP EBITDA margin, free cash flow and free cash flow conversion, that include certain adjustments or exclude certain charges and gains that are described in the reconciliation table of U.S. GAAP to non-GAAP information provided at the end of this section.

Organic revenue growth is a non-GAAP measure that reflects adjustments for: (i) the impact of period-over-period changes in foreign currency exchange rates, and (ii) the revenues, expenses and operating income associated with acquisitions and divestitures for the twelve-month period following the date of the acquisition or divestiture. Non-GAAP EBITDA is defined as non-GAAP net income plus interest, taxes, depreciation and amortization and non-GAAP EBITDA margin reflects non-GAAP net income plus interest, taxes, depreciation and amortization expenses. Free cash flow is defined as cash flow from operations less capital expenditures excluding Section 31 fees, net, and for 2021 excludes certain Verafin structuring items. Free cash flow conversion is calculated by dividing free cash flow by non-GAAP net income attributable to Nasdaq.

S-9

Management uses this non-GAAP information internally, along with U.S. GAAP information, in evaluating our performance and in making financial and operational decisions. We believe our presentation of these measures provides investors with greater transparency and supplemental data relating to our financial condition and results of operations. In addition, we believe the presentation of these measures is useful to investors for period-to-period comparisons of results as the items described below in the reconciliation tables do not reflect ongoing operating performance.

These measures are not in accordance with, or an alternative to, U.S. GAAP, and may be different from non-GAAP measures used by other companies. In addition, other companies, including companies in our industry, may calculate such measures differently, which reduces its usefulness as a comparative measure. Investors should not rely on any single financial measure when evaluating our business. This information should be considered as supplemental in nature and is not meant as a substitute for our operating results in accordance with U.S. GAAP. We recommend investors review the U.S. GAAP financial measures included in this prospectus supplement. When viewed in conjunction with our U.S. GAAP results and the accompanying reconciliations, we believe these non-GAAP measures provide greater transparency and a more complete understanding of factors affecting our business than U.S. GAAP measures alone.

We understand that analysts and investors regularly rely on non-GAAP financial measures to assess operating performance. We use these measures because they highlight trends more clearly in our business that may not otherwise be apparent when relying solely on U.S. GAAP financial measures, since these measures eliminate from our results specific financial items that have less bearing on our ongoing operating performance.

Foreign exchange impact: In countries with currencies other than the U.S. dollar, revenues and expenses are translated using monthly average exchange rates. Certain discussions in this prospectus supplement isolate the impact of year-over-year foreign currency fluctuations to better measure the comparability of operating results between periods. Operating results excluding the impact of foreign currency fluctuations are calculated by translating the current period’s results by the prior period’s exchange rates.

(1) Amortization expense of acquired intangible assets: We amortize intangible assets acquired in connection with various acquisitions. Intangible asset amortization expense can vary from period to period due to episodic acquisitions completed, rather than from our ongoing business operations.

(2) Merger and strategic initiatives expense: We have pursued various strategic initiatives and completed acquisitions and divestitures in recent years that have resulted in expenses which would not have otherwise been incurred. The frequency and the amount of such expenses vary significantly based on the size, timing and complexity of the transaction. These expenses primarily include integration costs, as well as legal, due diligence and other third-party transaction costs.

S-12

(3) Restructuring charges: In the fourth quarter of 2023, following the closing of the acquisition of Adenza Holdings, Inc. (the “Adenza transaction”), our management approved, committed to and initiated a restructuring program, to optimize our efficiencies as a combined organization. In connection with this program, we expect to incur pre-tax charges principally related to employee-related costs, contract terminations, real estate impairments and other related costs. The 2023 and 2022 charges also relate to our divisional alignment program that was initiated in October 2022, following our September 2022 announcement to realign our segments and leadership, with a focus on realizing the full potential of this structure. In connection with the program, we expect to incur pre-tax charges principally related to employee-related costs, consulting, asset impairments and contract terminations over a two-year period. The charges in 2019, 2020 and 2021 are associated with our restructuring program initiated in September 2019 with the goal of transitioning certain technology platforms to advance Nasdaq’s strategic opportunities as a technology and analytics provider and continuing our re-alignment of certain business areas. The 2019 program was completed as of June 30, 2021.

(4) Lease asset Impairments: During 2023, we initiated a review of our real estate and facility capacity requirements due to our new and evolving work models. As a result, we recorded impairment charges related to our operating lease assets and leasehold improvements associated with vacating certain leased office space, which are recorded in occupancy expense and depreciation and amortization expense in our Consolidated Statements of Income. We fully impaired our lease assets for locations we vacated, with no intention to sublease. Substantially all the property, equipment and leasehold improvements associated with the vacated lease office space was fully impaired as there are no expected future cash flows for these items.

(5) Net gain on divestiture of businesses: Represents the net gain on sale of our U.S. Fixed Income business in the second quarter of 2021, the net gain on the sale of the BWise enterprise governance, risk and compliance software platform in 2019 and the net gain on the sale of our Public Relations Solutions and Digital Media Services businesses in 2018.

(6) Net (income) loss from unconsolidated investees: We exclude our share of the earnings and losses of our equity method investments, primarily our equity interest in the Options Clearing Corporation, or OCC and Nasdaq Private Market, LLC. This provides a more meaningful analysis of Nasdaq’s ongoing operating performance or comparisons in Nasdaq’s performance between periods.

(7) Extinguishment of debt: These charges relate to premiums paid for the early extinguishment of previously outstanding debt.

(8) Legal and regulatory matters: For the year ended 2023 legal accruals were offset by insurance recoveries related to legal matters recorded in general, administrative and other expense and professional and contract services expense in our Consolidated Statements of Income. In December 2021, we recorded a $33 million charge related to a decision made by the Swedish Administrative court rejecting an appeal by Nasdaq Clearing to dismiss an administrative fine imposed by the Swedish Financial Supervisory Authority (SFSA) associated with the default of a member of the Nasdaq Clearing commodities market that occurred in 2018. Nasdaq Clearing has appealed the court’s recent decision and firmly believes in the merits of its appeal. For the year ended December 31, 2020, we recorded a $6 million reversal of a regulatory fine issued by the SFSA. Both charges were recorded to regulatory expense in our Consolidated Statements of Income.

(9) Gain on the sale of investment security: Represents a pre-tax gain on the sale of our 5.0% ownership interest in LCH Group Holdings Limited.

(10) Pension settlement charge: In 2023 we recognized a settlement charge relating to the termination and partial settlement of our U.S. pension plan related to the lump sum distributions. The charge was recorded in Compensation and Benefits expense in our Consolidated Statements of Income.

(11) Clearing default: Charges associated with the clearing default which occurred in 2018.

(12) Charitable donations: Donations made to the Nasdaq Foundation, COVID-19 response and relief efforts, and social justice charities.

(13) Provision for notes receivable: These charges are associated with the funding of technology development for the consolidated audit trail.

S-13

(14) Other significant items include certain other charges or gains, including certain tax items, that are the result of other non-comparable events to measure operating performance. For the year ended 2023, these items primarily included certain financing costs related to the Adenza transaction; for 2022, net gains and losses from strategic investments entered into through our corporate venture program; for 2021, gains from sales of strategic investments entered into through our corporate venture program; for 2020, charges associated with duplicative rent and impairment of leasehold assets related to our global headquarters move; for 2019, a tax reserve for certain prior year examinations and certain litigation costs; for 2018, certain litigation costs, certain charges related to a sales and use tax audit and VAT reserves.

(15) The non-GAAP adjustment to the income tax provision primarily includes the tax impact of each non-GAAP adjustment. For the year ended December 31, 2020, we also recorded a tax benefit on compensation related deductions determined to be allowable. For the year ended 2018, we recorded a reversal of previously recognized Swedish tax benefits. For the year ended 2017, we recorded a decrease to tax expense primarily related to the remeasurement of our net U.S. deferred tax liability at the lower U.S. federal corporate income tax rate which reflected the provisional impact associated with the enactment of this act. Also in 2017, we recorded excess tax benefits related to employee share-based compensation as a result of the adoption of accounting guidance on January 1, 2017.

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.

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-17

SELLING STOCKHOLDER

The following table sets forth information as of March 15, 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 575,758,581 shares of our common stock outstanding as of March 15, 2024.

Shares Beneficially Owned Before and After the Offering, Assuming the Underwriters’ Option is Not Exercised													Shares Beneficially Owned After the Offering, Assuming the Underwriters’ Option is Exercised in Full

(1) Borse Dubai Limited (“Borse Dubai”) is a wholly-owned subsidiary of the Investment Corporation of Dubai (“ICD”). As such, ICD is deemed to have beneficial ownership of all shares of common stock held by Borse Dubai and share in whatever voting power and dispositive power Borse Dubai has over the shares of common stock it holds. The address of ICD’s principal business and principal office is One Za’abeel The Offices, Tower A, Za’abeel First, Dubai, United Arab Emirates. The address of Borse Dubai’s principal business and principal office is P.O. Box 506690, Level 8, The Exchange, Dubai International Financial Centre, Dubai, United Arab Emirates. Borse Dubai has granted a first-priority security interest in the shares of common stock held by it to certain financial institutions in connection with its obligations under pledge agreements.

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 OMX AB. 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 OMX Transaction Agreement, dated November 15, 2007. 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.

Registration Rights Agreement

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

S-18

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 customary restrictions including, if a registration is underwritten, limitation on the number of shares to be included in the underwritten offering if the managing 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.

Stockholders’ Agreement and Proposed Amendment

Pursuant to the Stockholders’ Agreement, the selling stockholder is subject to certain specified transfer restrictions and has certain rights, including rights to indemnification in respect of claims arising out of the selling stockholder’s actual, alleged or deemed control or ability to influence us or any of our subsidiaries.

In addition, in connection with the pricing of this offering, we and the selling stockholder entered into an amendment to the Stockholders’ Agreement. The amendment provides that (i) for a period of 18 months from the date of this prospectus supplement, the selling stockholder will not, subject to certain exceptions, transfer, sell, assign or otherwise dispose of any shares of common stock beneficially owned by it, and (ii) so long as the selling stockholder continues to beneficially own at least 10% of the shares outstanding as of the date of this prospectus supplement, the selling stockholder will be entitled to nominate one person as a director on our board of directors (which person will initially be Essa Kazim, who has been a director on our board since March 1, 2008) and we will recommend such nominee for election and otherwise use our reasonable best efforts to cause such nominee to be elected to our board of directors. The foregoing description of the amendment to the Stockholders’ Agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, such amendment, which will be filed as an exhibit to a Current Report on Form 8-K.

Other Relationships

The selling stockholder has provided the following information: The selling stockholder is conducting this offering to enhance the capital structure and liquidity within the Borse Dubai Group. As of the date hereof, the selling stockholder continues to be a long-term stockholder in the Company and is invested in the success of the Company. The relationship between the Company and selling stockholder is multifaceted and has spanned many years. The selling stockholder has not only been a shareholder in the Company for the past 16 years, but the Company is also a key technology and brand partner for the selling stockholder’s exchange group. The selling stockholder believes in the strategic vision for the Company. The selling stockholder also looks forward to a continued relationship as a partner.

We are party to several commercial agreements with the selling stockholder and/or its affiliates that were negotiated on an arms-length basis and entered into in the ordinary course of business. Under these agreements, the selling stockholder or its affiliates paid Nasdaq approximately $1.7 million in 2023, primarily for marketplace technology and products and services.

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:

• a partnership;

• an individual who is a citizen or resident of the United States;

• a corporation created or organized in the United States or under the laws of the United States, any state thereof, or the District of Columbia;

• an estate, the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source; or

• a trust if (1) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more “United States persons” (as defined in the Code) have the authority to control all substantial decisions of such trust or (2) the trust has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person 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-20

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 share 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:

• the gain is effectively connected with a trade or business carried on by the non-U.S. holder within the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment or a fixed base of such non-U.S. holder in the United States);

• the non-U.S. holder is an individual who is present in the United States for a period or periods aggregating 183 or more days in the taxable year of the disposition and certain other conditions are met; or

• we are or have been a “United States real property holding corporation” within the meaning of Section 897(c)(2) of the Code (a “USRPHC”) for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of such disposition or such non-U.S. holder’s holding period of such shares of our common stock.

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-21

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.

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

S-22

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.

UNDERWRITING

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus supplement, the underwriters named below, for whom Morgan Stanley & Co. LLC and Goldman Sachs & Co. LLC are acting as representatives, have severally agreed to purchase, and the selling stockholder has agreed to sell to them, severally, the number of shares indicated below:

Name	Number of Shares
Morgan Stanley & Co. LLC		16,173,913
Goldman Sachs & Co. LLC		10,782,609
Total		26,956,522

The underwriters and the representatives are collectively referred to as the “underwriters” and the “representatives,” respectively. The underwriters are offering the shares of common stock subject to their acceptance of the shares from the selling stockholder and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of common stock offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of common stock offered by this prospectus supplement if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters’ option to purchase additional shares described below.

The underwriters initially propose to offer part of the shares of common stock directly to the public at the offering price listed on the cover page of this prospectus supplement and part to certain dealers at a price that represents a concession not in excess of $0.6018 per share under the public offering price. After the initial offering of the shares of common stock, the offering price and other selling terms may from time to time be varied by the representatives.

The selling stockholder has granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 4,043,478 additional shares of common stock at the public offering price listed on the cover page of this prospectus supplement, less the underwriting discount. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional shares of common stock as the number listed next to the underwriter’s name in the preceding table bears to the total number of shares of common stock listed next to the names of all underwriters in the preceding table.

The following table shows the per share and total public offering price, underwriting discount, and proceeds before expenses to the selling stockholder. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase up to an additional 4,043,478 shares of common stock.

	Per Share		Total
			No Exercise		Full Exercise
Public offering price	$	59.000	$	1,590,434,798	$	1,829,000,000
Underwriting discount to be paid by the selling stockholder	$	1.003	$	27,037,392	$	31,093,000
Proceeds, before expenses, to selling stockholder	$	57.997	$	1,563,397,406	$	1,797,907,000

The estimated offering expenses payable by us are approximately $2,000,000. Certain expenses are being reimbursed by the underwriters.

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

Pursuant to a stockholders’ agreement between us, Adenza Parent, LP and Thoma Bravo, L.P.

iv. transfers made pursuant to a bona fide third-party tender offer, merger, consolidation or other similar transaction that is approved by our board of directors and made to all holders of our capital stock involving a Change of Control (as defined in the lock-up agreement);

v. facilitating the establishment of a trading plan on behalf of one of our shareholders, officers or directors pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of common stock; provided that (i) such plan does not provide for the transfer of common stock during the restricted period, and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of Thoma Bravo or us regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of common stock may be made under such plan during the restricted period;

If the representatives waive or terminate any restrictions with respect to shares of common stock held by a lock-up party that has entered into a lock-up agreement substantially in the form entered into by Thoma Bravo (a “Triggering Release”), the restrictions on any shares of common stock held by Thoma Bravo will be automatically and concurrently waived or terminated to the same extent, on the same terms and in the same proportion as such lock-up party; provided, the Triggering Release will not apply with respect to any waivers or terminations of the restrictions relating to shares of common stock held by our directors or officers that have executed a lock-up agreement if the aggregate amount of such released shares does not exceed 1% of our total outstanding shares of common stock as determined on the closing date of this offering.

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

In order to facilitate the offering of the common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under the option. The underwriters can close out a covered short sale by exercising the option or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the option. The underwriters may also sell shares in excess of the option, creating a naked short position. The underwriters must close out any naked short position by purchasing shares 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 common stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of common stock in the open market to stabilize the price of the common stock. These activities may raise or maintain the market price of the common stock above independent market levels or prevent or retard a decline in the market price of the common stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

We, the selling stockholder and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

A prospectus in electronic format may be made available on websites maintained by one or more underwriters, or selling group members, if any, participating in this offering. The representatives may agree to allocate a number of shares of common stock to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters that may make Internet distributions on the same basis as other allocations.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they received or will receive customary fees and expenses. In addition, affiliates of certain underwriters act as agents and/or lenders under our existing revolving credit facility.

S-29

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

CAUTIONARY NOTE REGARDING 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:

• our strategic direction;

• the integration of acquired businesses, including accounting decisions relating thereto;

• the scope, nature or impact of acquisitions, divestitures, investments, joint ventures or other transactional activities;

• the effective dates for, and expected benefits of, ongoing initiatives, including transactional activities and other strategic, restructuring, technology, de-leveraging and capital return initiatives;

• our products and services;

• the impact of pricing changes;

• tax matters;

• the cost and availability of liquidity and capital;

• any litigation, or any regulatory or government investigation or action, to which we are or could become a party or which may affect us; and

• the potential impact of the COVID-19 pandemic and the response of governments and other third parties on our business, operations, results of operations, financial condition, workforce or the operations or decisions of our customers, suppliers or business partners.

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:

• our operating results may be lower than expected;

• our ability to successfully integrate acquired businesses or divest sold businesses or assets, including the fact that any integration or transition may be more difficult, time consuming or costly than expected, and we may be unable to realize synergies from business combinations, acquisitions, divestitures or other transactional activities;

• loss of significant trading and clearing volumes or values, fees, market share, listed companies, market data customers or other customers;

• our ability to develop and grow our non-trading businesses, including our technology and analytics offerings;

• our ability to keep up with rapid technological advances and adequately address cybersecurity risks;

• economic, political and market conditions and fluctuations, including interest rate and foreign currency risk, inherent in U.S. and international operations;

• the performance and reliability of our technology and technology of third parties on which we rely;

3

• any significant error in our operational processes;

• our ability to continue to generate cash and manage our indebtedness; and

• adverse changes that may occur in the litigation or regulatory areas, or in the securities markets generally, or increased regulatory oversight domestically or internationally.

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. These risk factors are discussed under the caption “Item 1A. Risk Factors,” in our Annual Report on Form 10-K. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this report. 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.

THE COMPANY

In January 2020, we commenced an orderly wind-down of our Nordic broker services operations business. We expect this wind-down to continue through 2021. Also, in February 2021, we announced that we entered into a purchase agreement to sell our U.S. fixed income business, Nasdaq Fixed Income, which transaction is expected to close later in 2021.

The platforms allow the routing and execution of buy and sell orders as well as the reporting of transactions, providing fee-based revenues.

RISK FACTORS

Investing in our securities involves risk. See the risk factors described in our most recent Annual Report on Form 10-K (together with any material changes thereto contained in subsequently filed Quarterly Reports on Form 10-Q) and those contained in our other filings with the SEC that are incorporated by reference in this prospectus and any accompanying prospectus supplement. Before making an investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus and any accompanying prospectus supplement. These risks could materially affect our business, financial condition or results of operations and cause the value of our securities to decline. You could lose all or part of your investment.

USE OF PROCEEDS

Except as otherwise set forth in any accompanying prospectus supplement, we expect to use the net proceeds from the sale of securities for general corporate purposes, including the financing of our operations, the possible repayment of indebtedness, and possible business acquisitions.

Unless set forth in an accompanying prospectus supplement, we will not receive any proceeds in the event that securities are sold by a selling securityholder.

DESCRIPTION OF SECURITIES

This prospectus contains summary descriptions of the common stock, preferred stock, depositary shares, debt securities, warrants, subscription rights, purchase contracts and purchase units that may be offered and sold from time to time. These summary descriptions are not meant to be complete descriptions of each security. However, at the time of an offering and sale, this prospectus together with the accompanying prospectus supplement, and if applicable, any free writing prospectus, will contain the material terms of the securities being offered.

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

6

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) 300,000,000 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, 2021, there were 164,242,583 shares of our common stock outstanding and no shares of preferred stock outstanding. As of March 31, 2021, we had approximately 225 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 shareholder 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 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 designation of the series, which may be by distinguishing number, letter or title;

7

• the number of shares within the series;

• whether dividends are cumulative and, if cumulative, the dates from which dividends are cumulative;

• the rate of any dividends, any conditions upon which dividends are payable, and the dates of payment of dividends;

• whether the shares are redeemable, the redemption price and the terms of redemption;

• the amount payable for each share if we dissolve or liquidate;

• whether the shares are convertible or exchangeable, the price or rate of conversion or exchange, and the applicable terms and conditions;

• any restrictions on issuance of shares in the same series or any other series;

• voting rights applicable to the series of preferred stock; and

• any other rights, priorities, preferences, restrictions or limitations of such series.

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 shareholder 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 10^th 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 10^th day 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 shareholders, 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:

• prior to such time, the board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

• upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the corporation’s voting stock outstanding at the time the transaction commenced, excluding certain shares; or

• at or subsequent to that time, the business combination is approved by the board of directors of the corporation and by the affirmative vote of holders of at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.

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.

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.

10

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 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.

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:

• the title and aggregate principal amount of the debt securities and any limit on the aggregate principal amount of such series;

• any applicable subordination provisions for any subordinated debt securities;

• the maturity date(s) or method for determining same;

• the interest rate(s) or the method for determining same;

11

• the dates on which interest will accrue or the method for determining dates on which interest will accrue and dates on which interest will be payable and whether interest will be payable in cash, additional securities or some combination thereof;

• whether the debt securities are convertible or exchangeable into other securities and any related terms and conditions;

• redemption or early repayment provisions;

• authorized denominations;

• if other than the principal amount, the principal amount of debt securities payable upon acceleration;

• place(s) where payment of principal and interest may be made, where debt securities may be presented and where notices or demands upon the company may be made;

• the form or forms of the debt securities of the series including such legends as may be required by applicable law;

• whether the debt securities will be issued in whole or in part in the form of one or more global securities and the date as of which the securities are dated if other than the date of original issuance;

• whether the debt securities are secured and the terms of such security;

• the amount of discount or premium, if any, with which the debt securities will be issued;

• any covenants applicable to the particular debt securities being issued;

• any additions or changes in the defaults and events of default applicable to the particular debt securities being issued;

• the guarantors of each series, if any, and the extent of the guarantees (including provisions relating to seniority, subordination and release of the guarantees), if any;

• the currency, currencies or currency units in which the purchase price for, the principal of and any premium and any interest on, the debt securities will be payable;

• the time period within which, the manner in which and the terms and conditions upon which we or the holders of the debt securities can select the payment currency;

• our obligation or right to redeem, purchase or repay debt securities under a sinking fund, amortization or analogous provision;

• any restriction or conditions on the transferability of the debt securities;

• provisions granting special rights to holders of the debt securities upon occurrence of specified events;

• additions or changes relating to compensation or reimbursement of the trustee of the series of debt securities;

• provisions relating to the modification of the indenture both with and without the consent of holders of debt securities issued under the indenture and the execution of supplemental indentures for such series; and

• any other terms of the debt securities (which terms shall not be inconsistent with the provisions of the TIA, but may modify, amend, supplement or delete any of the terms of the indenture with respect to such series of debt securities).

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.

12

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.

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.

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:

• the offering price;

• the currency or currencies, including composite currencies, in which the purchase price and/or exercise price of the warrants may be payable;

• the number of warrants offered;

13

• the exercise price and the amount of securities you will receive upon exercise;

• the procedure for exercise of the warrants and the circumstances, if any, that will cause the warrants to be automatically exercised;

• the rights, if any, we have to redeem the warrants;

• the date on which the right to exercise the warrants will commence and the date on which the warrants will expire;

• the name of the warrant agent; and

• any other material terms of the warrants.

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.

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:

• the price, if any, for the subscription rights;

• the number and terms of each share of common stock or preferred stock or debt securities which may be purchased per each subscription right;

• the exercise price payable for each share of common stock or preferred stock or debt securities upon the exercise of the subscription rights;

• the extent to which the subscription rights are transferable;

• any provisions for adjustment of the number or amount of securities receivable upon exercise of the subscription rights or the exercise price of the subscription rights;

• any other terms of the subscription rights, including the terms, procedures and limitations relating to the exchange and exercise of the subscription rights;

• the date on which the right to exercise the subscription rights shall commence, and the date on which the subscription rights shall expire;

14

• the extent to which the subscription rights may include an over-subscription privilege with respect to unsubscribed securities; and

• if applicable, the material terms of any standby underwriting or purchase arrangement entered into by us in connection with the offering of subscription rights.

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

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.

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.

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:

• to underwriters for resale to purchasers;

• directly to purchasers;

15

• through agents or dealers to purchasers;

• in “at-the market” offerings (as defined in Rule 415 under the Securities Act);

• through a combination of any of these methods; or

• through any other method permitted by applicable law and described in a prospectus supplement.

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:

• the terms of the offering;

• the names of the underwriters, dealers, agents or direct purchasers and their compensation;

• the purchase price of the securities and the net proceeds we will receive from the sale;

• any delayed delivery obligations to take the securities;

• the nature of the underwriters’ obligations to take the securities;

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

• other facts material to the transaction.

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.

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.

16

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 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 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.

17

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.

LEGAL MATTERS

Unless otherwise indicated in any accompanying prospectus supplement, Skadden, Arps, Slate, Meagher & Flom LLP will provide opinions regarding the authorization and validity of the securities. Skadden, Arps, Slate, Meagher & Flom LLP may also provide opinions regarding certain other matters. Any underwriters will be advised about legal matters by their own counsel, which will be named in an accompanying prospectus supplement.
