PROSPECTUS SUPPLEMENT

(To Prospectus dated March 21, 2025)

BlackRock, Inc.

Guaranteed on a senior unsecured basis by BlackRock Finance, Inc.

€1,000,000,000 3.750% NOTES DUE 2035

The €1,000,000,000 aggregate principal amount of 3.750% Notes due 2035 (the “notes”) will bear interest at the rate of 3.750% per year and mature on July 18, 2035.

Interest on the notes is payable annually in arrears on July 18 of each year, beginning on July 18, 2025 (short first coupon).

The notes will be unsecured and unsubordinated debt obligations of BlackRock, Inc. (“BlackRock”) and will be fully and unconditionally guaranteed (the “note guarantee”), on a senior unsecured basis by BlackRock Finance, Inc., a direct wholly owned subsidiary of BlackRock (“BlackRock Finance”). The notes and the note guarantee will rank equally in right of payment with all of BlackRock and BlackRock Finance’s other unsubordinated indebtedness, respectively, from time to time outstanding.

We may redeem the notes, in whole or in part, at any time at the redemption price described under “Description of the Notes—Optional Redemption of the Notes.”

Investing in the notes involves risks, including those described in the “Risk Factors” section beginning on page S-14 of this prospectus supplement and the section entitled “Risk Factors” beginning on page 19 of BlackRock’s Annual Report on Form 10-K for the year ended December 31, 2024, which is incorporated by reference into this prospectus supplement.

Interest on the notes will accrue from April 3, 2025.

Currently there is no public market for the notes. We intend to apply to list the notes on the New York Stock Exchange (“NYSE”). The listing application will be subject to approval by the NYSE. We expect trading in the notes on the NYSE to begin within 30 days after the original issue date. If such a listing is obtained, we have no obligation to monitor such listing, and we may delist the notes at any time.

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

The underwriters expect to deliver the notes to purchasers in book-entry form only through the facilities of Clearstream Banking, S.A. (“Clearstream”), and Euroclear Bank, SA/NV (“Euroclear”), on or about April 3, 2025 which is the seventh business day following the date of this prospectus supplement.

PRIIPs Regulation/Prohibition of Sales to EEA Retail Investors

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

PRIIPs Regulation/Prohibition of Sales to United Kingdom Retail Investors

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom. For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018 (as amended, the “EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the “FSMA”) and any rules or regulations made under the FSMA to implement the Directive (EU) 2016/97, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of UK domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of the Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA (the “UK Prospectus Regulation”). Consequently, no key information document required by the PRIIPs Regulation (EU) No 1286/2014 as it forms part of UK domestic law by virtue of the EUWA (as amended, the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in the United Kingdom will be made pursuant to an exemption under the UK Prospectus Regulation from the requirement to publish a prospectus for offers of the notes.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus, including the documents incorporated by reference herein and therein, and other statements that BlackRock may make, may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act, with respect to BlackRock’s future financial or business performance, strategies or expectations. Forward-looking statements are typically identified by words or phrases such as “trend,” “potential,” “opportunity,” “pipeline,” “believe,” “comfortable,” “expect,” “anticipate,” “current,” “intention,” “estimate,” “position,” “assume,” “outlook,” “continue,” “remain,” “maintain,” “sustain,” “seek,” “achieve,” and similar expressions, or future or conditional verbs such as “will,” “would,” “should,” “could,” “may” and similar expressions.

BlackRock cautions that forward-looking statements are subject to numerous assumptions, risks and uncertainties, which change over time and may contain information that is not purely historical in nature. Such information may include, among other things, projections and forecasts. There is no guarantee that any forecasts made will come to pass. Forward-looking statements speak only as of the date they are made, and BlackRock assumes no duty to and does not undertake to update forward-looking statements. Actual results could differ materially from those anticipated in forward-looking statements and future results could differ materially from historical performance.

BlackRock has previously disclosed risk factors in its SEC reports. These risk factors and those identified elsewhere in this prospectus supplement, among others, could cause actual results to differ materially from forward-looking statements or historical performance and include: (1) the introduction, withdrawal, success and timing of business initiatives and strategies; (2) changes and volatility in political, economic or industry conditions, the interest rate environment, foreign exchange rates or financial and capital markets, which could result in changes in demand for products or services or in the value of assets under management (“AUM”); (3) the relative and absolute investment performance of BlackRock’s investment products; (4) BlackRock’s ability to develop new products and services that address client preferences; (5) the impact of increased competition; (6) the impact of recent or future acquisitions or divestitures, including the planned acquisition of HPS Investment Partners (“HPS” or the “HPS Transaction”) and the acquisitions of Global Infrastructure Management, LLC (“GIP” or the “GIP Transaction”) and Preqin Holdings Limited (and together with the HPS Transaction and the GIP Transaction, the “Transactions”); (7) BlackRock’s ability to integrate acquired businesses successfully, including the Transactions; (8) risks related to the HPS Transaction, including delays in the expected closing date of the HPS Transaction, the possibility that the HPS Transaction does not close, including, but not limited to, due to the failure to satisfy the closing conditions; the possibility that expected synergies and value creation from the Transactions will not be realized, or will not be realized within the expected time period; and the risk of impacts to business and operational relationships related to disruptions from the Transactions; (9) the unfavorable resolution of legal proceedings; (10) the extent and timing of any share repurchases; (11) the impact, extent and timing of technological changes and the adequacy of intellectual property, data, information and cybersecurity protection; (12) the failure to effectively manage the development and use of artificial intelligence; (13) attempts to circumvent BlackRock’s operational control environment or the potential for human error in connection with BlackRock’s operational systems; (14) the impact of legislative and regulatory actions and reforms, regulatory, supervisory or enforcement actions of government agencies and governmental scrutiny relating to BlackRock; (15) changes in law and policy and uncertainty pending any such changes; (16) any failure to effectively manage conflicts of interest; (17) damage to BlackRock’s reputation; (18) increasing focus from stakeholders regarding environmental and social-related matters; (19) geopolitical unrest, terrorist activities, civil or international hostilities, and other events outside BlackRock’s control, including wars, natural disasters and health crises, which may adversely affect the general economy, domestic and local financial and capital markets, specific industries or BlackRock; (20) climate-related risks to BlackRock’s business, products, operations and clients; (21) the ability to attract, train and retain highly qualified professionals; (22) fluctuations in the carrying value of BlackRock’s economic investments; (23) the impact of changes to tax legislation, including income, payroll and transaction taxes, and taxation on products, which could affect the value proposition to clients and, generally, the tax position of BlackRock; (24) BlackRock’s success in

S-4

negotiating distribution arrangements and maintaining distribution channels for its products; (25) the failure by key third-party providers to fulfill their obligations to BlackRock; (26) operational, technological and regulatory risks associated with BlackRock’s major technology partnerships; (27) any disruption to the operations of third parties whose functions are integral to BlackRock’s exchange-traded funds (“ETFs”) platform; (28) the impact of BlackRock electing to provide support to its products from time to time and any potential liabilities related to securities lending or other indemnification obligations; and (29) the impact of problems, instability or failure of other financial institutions or the failure or negative performance of products offered by other financial institutions.

You should carefully read the risk factors described in “Risk Factors” including in this prospectus supplement and in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus for a description of certain risks that could, among other things, cause our actual results to differ from these forward-looking statements.

RISK FACTORS

Any investment in the notes involves a high degree of risk. You should carefully consider the risks described below and all of the information contained in this prospectus supplement and the accompanying prospectus before deciding whether to purchase the notes. In addition, you should carefully consider, among other things, the matters discussed under “Risk Factors” in BlackRock’s Annual Report on Form 10-K for the year ended December 31, 2024, and other documents that BlackRock subsequently files with the SEC, all of which are incorporated by reference into this prospectus supplement. The risks and uncertainties described below, and in BlackRock’s Annual Report on Form 10-K for the year ended December 31, 2024, are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. If any such risks actually occur, our business, financial condition and results of operations would suffer.

Risks Related to the Offering

Our indebtedness could limit cash flow available for our operations, could adversely affect our ability to service debt or obtain additional financing if necessary, or reduce our flexibility in planning for, or reacting to, changes in the market.

As of December 31, 2024, we had outstanding an aggregate carrying value of $12.3 billion of unsecured long-term indebtedness. Our indebtedness could limit our flexibility in planning for, or reacting to, changes in the market in which we compete. Although we believe we have adequate sources of liquidity to meet our anticipated requirements for working capital, debt service, capital expenditures and cash dividend payments, there can be no assurance that our cash flow from operations will be sufficient to service our debt, which may require us to borrow additional funds for that purpose, restructure or otherwise refinance our debt.

The notes and the note guarantee are obligations of BlackRock and BlackRock Finance, respectively, and not of our other subsidiaries and payment to holders of the notes will be structurally subordinated to the claims of such other subsidiaries’ creditors.

The notes are not guaranteed by any other subsidiary of BlackRock or BlackRock Finance. As a result, liabilities, including indebtedness or guarantees of indebtedness, of such subsidiaries will be structurally senior to the indebtedness represented by the notes and the note guarantee, respectively, to the extent of such subsidiary’s assets. In addition, the indenture governing the notes will not restrict the future incurrence of liabilities or issuances of preferred stock, including unsecured indebtedness or guarantees of indebtedness, by our other subsidiaries.

The notes and the note guarantee will be effectively junior to secured indebtedness that BlackRock or BlackRock Finance may issue in the future.

The notes and the note guarantee are unsecured. Holders of any secured debt that BlackRock or BlackRock Finance, respectively, may issue in the future may foreclose on the assets securing such debt, reducing the cash flow from the foreclosed property available for payment of unsecured debt, including the notes and the note guarantee. Holders of BlackRock’s and BlackRock Finance’s secured debt also would have priority over unsecured creditors in the event of the bankruptcy, liquidation or similar proceeding of BlackRock or BlackRock Finance, as applicable. As a result, the notes and the note guarantee will be effectively junior to any secured debt that BlackRock and BlackRock Finance, respectively, may issue in the future.

An active trading market for the notes may not develop, which could limit their market price or your ability to sell them.

The notes are a new issue of securities for which there is currently no public trading market. We can give no assurances concerning the liquidity of any market that may develop for the notes offered hereby, the ability of

S-14

any investor to sell the notes, or the price at which investors would be able to sell them. If a market for the notes does not develop, investors may be unable to resell the notes for an extended period of time, if at all. If a market for the notes does develop, it may not continue or it may not be sufficiently liquid to allow holders to resell any of the notes. Consequently, investors may not be able to liquidate their investment readily, and lenders may not readily accept the notes as collateral for loans.

Although we intend to apply for listing of the notes for trading on the NYSE, no assurance can be given that the notes will become or will remain listed or that an active trading market for the notes will develop or, if developed, that it will continue. The listing application will be subject to approval by the NYSE. If such a listing is obtained, we have no obligation to maintain such listing, and we may delist the notes at any time.

Holders of the notes will receive payments in euros.

All payments of interest on and the principal of the notes and any redemption price for the notes will be made in euros, subject to certain limited exceptions. We, the underwriters, the trustee and the paying agent with respect to the notes will not be obligated to convert, or to assist any registered owner or beneficial owner of notes in converting, payments of interest, principal, any redemption price or any additional amount in euros made with respect to the notes into U.S. dollars or any other currency.

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

The initial investors in the notes will be required to pay for the notes in euros. Neither we nor the underwriters will be obligated to assist the initial investors in obtaining euros or in converting other currencies into euros to facilitate the payment of the purchase price for the notes.

An investment in any security denominated in, and all payments with respect to which are to be made in, a currency other than the currency of the country in which an investor in the notes resides or the currency in which an investor conducts its business or activities (the “investor’s home currency”), entails significant risks not associated with a similar investment in a security denominated in the investor’s home currency. In the case of the notes offered hereby, these risks may include the possibility of:

In addition, if one or more member states of the European Monetary Union were to withdraw from the European Monetary Union and cease to use the euro as their currency, the value of the euro could be materially adversely affected.

We have no control over a number of factors affecting the notes offered hereby and foreign exchange rates, including economic, financial and political events that are important in determining the existence, magnitude and longevity of these risks and their effects. Changes in foreign currency exchange rates between two currencies result from the interaction over time of many factors directly or indirectly affecting economic and political conditions in the countries issuing such currencies, and economic and political developments globally and in other relevant countries. Foreign currency exchange rates may be affected by, among other factors, existing and expected rates of inflation, existing and expected interest rate levels, the balance of payments between countries, and the extent of the governmental surpluses or deficits in various countries. All of these factors are, in turn, sensitive to the monetary, fiscal and trade policies pursued by the governments of various countries important to international trade and finance. Moreover, the recent global economic volatility and the actions taken or to be taken by various national governments in response to the volatility could significantly affect the exchange rates between the euro and the investor’s home currency.

S-15

The exchange rates of an investor’s home currency for euros and the fluctuations in those exchange rates that have occurred in the past are not necessarily indicative of the exchange rates or the fluctuations therein that may occur in the future. Depreciation of the euro against the investor’s home currency would result in a decrease in the investor’s home currency equivalent yield on a note, in the investor’s home currency equivalent of the principal payable at the maturity of that note and generally in the investor’s home currency equivalent market value of that note. Appreciation of the euro in relation to the investor’s home currency would have the opposite effects.

The European Union or one or more of its member states (a “Member State”) may, in the future, impose exchange controls and modify any exchange controls imposed, which controls could affect exchange rates, as well as the availability of euros at the time of payment of principal of, interest on, or any redemption or additional amounts with respect to, the notes.

This description of foreign exchange risks does not describe all the risks of an investment in securities, including, in particular, the notes, that are denominated or payable in a currency other than an investor’s home currency. You should consult your own financial and legal advisors as to the risks involved in an investment in the notes.

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

We will pay the principal of and interest on each note to the registered holder in euros in immediately available funds; provided that, if on or after the issuance of the notes, the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us or so used. In such circumstances, the amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board at the close of business on the second business day prior to the relevant payment date or, in the event that the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the then-most recent U.S. dollar/euro exchange rate available on or prior to the second business day prior to the relevant payment date as determined by us in our sole discretion. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture governing the notes. This exchange rate may be materially less favorable than the rate in effect at the time the notes were issued or as would be determined by applicable law. Such developments, or market perceptions concerning these and related issues, could materially adversely affect the value of the notes and you may lose a significant amount of your investment in the notes.

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

The indenture and the notes will be governed by the laws of the State of New York. Under New York law, a New York state court rendering a judgment on the notes would be required to render the judgment in euros. However, the judgment would be converted into U.S. dollars at the exchange rate prevailing on the date of entry of the judgment. Consequently, in a lawsuit for payment on the notes, investors would bear currency exchange risk until a New York state court judgment is entered, which could be a significant amount of time. A federal court sitting in New York with diversity jurisdiction over a dispute arising in connection with the notes would apply New York law.

In courts outside of New York, investors may not be able to obtain a judgment in a currency other than U.S. dollars. For example, a judgment for money in an action based on the notes in many other U.S. federal or state courts ordinarily would be enforced in the United States only in U.S. dollars. The date used to determine the rate of conversion of euros into U.S. dollars will depend upon various factors, including which court renders the judgment and when the judgment is rendered.

S-16

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

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

The notes will initially be held in book-entry form and therefore investors must rely on the procedures of the relevant clearing systems to exercise any rights and remedies.

The notes will initially only be issued in global certificated form and held through Euroclear and Clearstream. Interests in the global notes (as such term is defined in “Description of the Notes—Global Settlement and Clearance”) will trade in book-entry form only. Unless and until the notes in definitive registered form are issued in exchange for book-entry interests, owners of book-entry interests will not be considered owners or holders of the notes. The common depositary (or its nominee) for the accounts of Euroclear and Clearstream will be the registered holder of the global notes. Payments in respect of the global notes representing the notes (including principal, premium, interest and additional amounts, if any) will be made to the paying agent. The paying agent will then make such payments to the common depositary (or its nominee) for Euroclear and Clearstream. The common depositary (or its nominee) will in turn distribute such payments to participants in accordance with its procedures. After payment to the common depositary (or its nominee), we, the trustee and the paying agent will have no responsibility or liability for the payment of interest, principal or other amounts to the owners of book-entry interests. Accordingly, if you own a book-entry interest, you must rely on the procedures of Euroclear or Clearstream, as applicable, and if you are not a participant in Euroclear or Clearstream, on the procedures of the participant through which you own your interest, to exercise any rights and obligations of a holder of notes under the indenture. See “Description of the Notes—Global Settlement and Clearance.” Payments in respect of the global notes representing the notes (including principal, premium, interest and additional amounts, if any) will be made to the paying agent one business day prior to the date such payment is due.

Unlike the holders of the notes themselves, owners of book-entry interests will not have the direct right to act upon our solicitations for consents, requests for waivers or other actions from holders of the notes. Instead, if you own a book-entry interest, you will be permitted to act only to the extent you have received appropriate proxies to do so from Euroclear or Clearstream or, if applicable, a participant. There can be no assurance that procedures implemented for the granting of such proxies will be sufficient to enable you to vote on any request actions on a timely basis.

Similarly, upon the occurrence of an event of default under the indenture, unless and until notes in definitive registered form are issued in respect of all book-entry interests, if you own a book-entry interest, you will be restricted to acting through Euroclear or Clearstream. We, the trustee and the paying agent cannot assure you that the procedures to be implemented through Euroclear or Clearstream will be adequate to ensure the timely exercise of rights under the notes. See “Description of the Notes—Global Settlement and Clearance.”

BLACKROCK’S SELECTED CONSOLIDATED HISTORICAL FINANCIAL DATA

The selected consolidated historical income statement data for the years ended December 31, 2024, 2023 and 2022, and the selected consolidated historical balance sheet data as of December 31, 2024 and 2023, presented below have been derived from BlackRock’s audited consolidated financial statements. Historical results are not necessarily indicative of results to be expected for any future period. All financial data presented in this prospectus supplement has been prepared in accordance with United States generally accepted accounting principles.

On October 1, 2024, we completed the GIP Transaction. As a result of the closing of the GIP Transaction, (1) BlackRock, Inc. (formerly known as BlackRock Funding, Inc.) (“New BlackRock”) became the ultimate parent company of BlackRock Finance, Inc. (formerly known as BlackRock, Inc.)

CURRENCY CONVERSION

All payments of interest and principal, including payments made upon any redemption of the notes, will be payable in euros. If the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us and so used. In such circumstances, the amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second business day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. dollar/euro exchange rate published in The Wall Street Journal on or prior to the second business day prior to the relevant payment date. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture governing the notes.

Investors will be subject to foreign exchange risks as to payments of principal and interest, including payments made upon any redemption of the notes, that may have important economic and tax consequences to them. See “Risk Factors” in this prospectus supplement.

Unless otherwise specified, the euro / U.S. dollar rate of exchange with respect to the notes used in this prospectus supplement is €1.00 = $1.08, as of noon, New York City time on March 25, 2025, on the Bloomberg page “BFIX.”

USE OF PROCEEDS

We estimate the net proceeds from this offering will be approximately €995.0 million, after deducting the underwriting discount and before deducting other estimated offering expenses payable by us.

We intend to use the net proceeds from this offering for general corporate purposes, which may include repayment of any or all of our outstanding 1.25% Notes due 2025. This prospectus supplement does not constitute a notice of redemption with respect to our outstanding 1.250% Notes due 2025 nor an obligation to issue a notice of redemption for such notes or any other outstanding series of notes. Any such notice, if given, will only be given in accordance with the provisions of such notes.

DESCRIPTION OF THE NOTES

Set forth below is a description of the specific terms of the notes. Reference should be made to the accompanying prospectus under the caption “Description of Debt Securities” for a detailed summary of additional provisions of the notes, the Guarantee (as defined herein) and the indenture, to be dated as of April 3, 2025, among BlackRock, BlackRock Finance and The Bank of New York Mellon, as trustee, which we refer to in this prospectus supplement as the “base indenture” (a form of which is filed as an exhibit to the registration statement of which this prospectus supplement forms a part), as supplemented by the first supplemental indenture, to be dated as of April 3, 2025, among BlackRock, BlackRock Finance, the trustee and The Bank of New York Mellon, London Branch, as paying agent, which we refer to as the “first supplemental indenture.” When we refer to the “indenture,” we mean the base indenture, as supplemented by the first supplemental indenture. The following description is a summary of selected portions of the base indenture and the first supplemental indenture. It does not restate the base indenture or the first supplemental indenture, and those documents, not this description, define your rights as a holder of the notes. If the description of the notes in this prospectus supplement differs from the description of debt securities in the accompanying prospectus, the description of the notes in this prospectus supplement supersedes the description of debt securities in the accompanying prospectus.

References in this “Description of the Notes” section to “we,” “our,” “ours,” and “us” refer to BlackRock, Inc. and its consolidated subsidiaries, including BlackRock Finance, Inc. References to “BlackRock” refer to BlackRock, Inc. and its successors, as the issuer of the notes offered hereby. References to “BlackRock Finance” refer to BlackRock Finance, Inc. and its successors, as the guarantor of the notes offered hereby.

General

The notes will initially be limited to €1,000,000,000 in aggregate principal amount. The notes will be issued in fully registered form only, in denominations of €100,000 and integral multiples of €1,000 in excess thereof. The notes will mature on July 18, 2035.

The notes will be issued as a separate series of senior debt securities under the indenture. The indenture will not limit the amount of other debt that we may incur. BlackRock may, from time to time, without the consent of the holders of the notes, issue other debt securities under the indenture in addition to the notes. BlackRock may also, from time to time, without the consent of the holders of the notes, issue additional debt securities having the same priority and the same interest rate, maturity and other terms (except for the issue date, public offering price and, in some cases, the first interest payment date and the initial interest accrual date) as the notes. Any such additional debt securities, together with the previously issued notes, will constitute a single series of debt securities under the indenture, provided that if the additional debt securities are not fungible with the notes of such series for U.S. federal income tax purposes, such additional debt securities will be issued with a separate CUSIP, ISIN or other identifying number.

The notes will bear interest from April 3, 2025, at the annual rate of 3.750%. Interest on the notes will be payable annually in arrears on July 18 of each year, commencing July 18, 2025 (short first coupon) to the persons in whose names the notes are registered at the close of business on the Clearing System Business Day prior to the date for payment, where “Clearing System Business Day” means every Monday to Friday, inclusive, except December 25^th and January 1^st, subject to certain exceptions. Interest on the notes will be computed by us, on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the notes (or from and including April 3, 2025 if no interest has been paid on the notes), to, but excluding, the next scheduled interest payment date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Market Association.

If any interest payment date, maturity date or redemption date is not a business day, then the related payment for such interest payment date, maturity date or redemption date will be made on the next succeeding

S-22

business day with the same force and effect as if made on such interest payment date, maturity date or redemption date, as the case may be, and no further interest will accrue as a result of such delay. The term “business day” means any day, other than a Saturday or Sunday, (1) which is not a day on which banking institutions in the City of New York or the City of London are authorized or required by law or executive order to close and (2) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates. The rights of holders of beneficial interests of notes to receive the payments of interest on such notes are subject to the applicable procedures of Euroclear and Clearstream.

The notes will be unsecured and unsubordinated obligations of BlackRock and will rank equal in right of payment to each other and to all of BlackRock’s other unsubordinated indebtedness.

The notes do not provide for any sinking fund.

Guarantee of Notes

BlackRock Finance will fully and unconditionally guarantee the payment of the notes offered hereby pursuant to a guarantee (the “Guarantee”) to be included in the indenture governing the notes. If BlackRock defaults in the payment of the principal of, or premium, if any, or interest on, such notes when and as the same shall become due, whether upon maturity, acceleration, or otherwise, without the necessity of action by the trustee or any holder of such notes, BlackRock Finance shall be required to promptly and fully make such payment.

Except as provided below, BlackRock Finance’s guarantee will be a continuing guarantee and will inure to the benefit of and be enforceable by the trustee, the holders of the notes and their successors, transferees and assigns.

Anything to the contrary notwithstanding, the Guarantee will be automatically and unconditionally released and discharged, and BlackRock Finance will be released from all obligations under the indenture in its capacity as guarantor, and no further action of BlackRock, BlackRock Finance or the trustee will be required for the release of the Guarantee:

The Guarantee will not be subject to release or revocation otherwise than as set forth above and as set forth in the accompanying prospectus under the caption “Description of Debt Securities—Modification of Indenture.”

S-23

For purposes of the foregoing discussion, the following definition applies:

“BlackRock Finance Notes” means as of any time of determination, the (i) 1.250% Notes due 2025, (ii) 3.200% Notes due 2027, (iii) 3.250% Notes due 2029, (iv) 2.400% Notes due 2030, (v) 1.900% Notes due 2031, (vi) 2.10% Notes due 2032 and (vii) the 4.750% Notes due 2033, in each case, previously issued by BlackRock Finance, and outstanding as of such time. BlackRock currently guarantees the BlackRock Finance Notes.

Issuance in Euros; Payment on the Notes

Initial holders will be required to pay for the notes in euros, and all payments on the notes will be payable in euros; provided that if on or after the date of this prospectus supplement the euro is unavailable to us due to the imposition of exchange controls or other circumstances beyond our control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the notes will be made in U.S. dollars until the euro is again available to us or so used. The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second business day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. dollar/euro exchange rate published in The Wall Street Journal on or prior to the second business day prior to the relevant payment date. Any payment in respect of the notes so made in U.S. dollars will not constitute an event of default under the notes or the indenture. Neither the trustee nor the paying agent will have any responsibility for any calculation or conversion in connection with the foregoing.

Investors will be subject to foreign exchange risks as to payments on the notes that may have important economic and tax consequences to them. See “Risk Factors” in this prospectus supplement.

Paying Agent and Registrar

The Bank of New York Mellon, London Branch, will initially act as paying agent for the notes. The Bank of New York Mellon, will initially act as security registrar for the notes. Upon notice to the trustee, we may change any paying agent or security registrar.

Optional Redemption of the Notes

At its option, BlackRock may redeem the notes, in whole, at any time, or in part, from time to time, prior to April 18, 2035 (three months prior to the maturity date for the notes) (the “Par Call Date”) at a redemption price equal to the greater of (i) 100% of the principal amount of the notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the notes to be redeemed (exclusive of interest accrued to the date of redemption), discounted to the redemption date on an annual basis (ACTUAL/ACTUAL (ICMA)), at the applicable Comparable Government Bond Rate described below plus 15 basis points, plus, in each case, accrued and unpaid interest on the notes to be redeemed to, but excluding, the date of redemption. BlackRock will calculate the redemption price.

On or after the Par Call Date, BlackRock may redeem the notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

“Comparable Government Bond Rate” means, with respect to any redemption date, the rate per annum equal to the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third business day prior to the date fixed for redemption, calculated in accordance with customary financial practice in pricing new issues of comparable corporate debt securities paying interest on an

S-24

annual basis (ACTUAL/ACTUAL (ICMA)) of the Comparable Government Bond (as defined herein), assuming a price for the Comparable Government Bond (expressed as a percentage of its principal amount) equal to the Comparable Government Bond Price for such redemption date.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, the German government bond (Bundesanleihe) selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities of a comparable maturity to the remaining term of such notes.

“Independent Investment Banker” means one of the Reference Government Bond Dealers selected by us.

“Comparable Government Bond Price” means, with respect to any redemption date, (1) the arithmetic average of the Reference Government Bond Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Government Bond Dealer Quotations, or (2) if we obtain fewer than four such Reference Government Bond Dealer Quotations, the arithmetic average of all such quotations.

“Reference Government Bond Dealer Quotations” means, with respect to each Reference Government Bond Dealer and any redemption date, the arithmetic average, as determined by us, of the bid and asked prices for the Comparable Government Bond (expressed in each case as a percentage of its principal amount) quoted in writing to us by such Reference Government Bond Dealer at 11:00 a.m., Central European Time (CET), on the third business day preceding such redemption date.

“Reference Government Bond Dealer” means each of (i) BNP PARIBAS, Deutsche Bank AG, London Branch and J.P. Morgan Securities plc or any of their affiliates that are primary European government securities dealers, and their respective successors; provided that if any of the foregoing or any of their affiliates shall cease to be a primary European government securities dealer (“Primary Dealer”), we shall substitute therefor another Primary Dealer and (ii) two other Primary Dealers selected by us.

BlackRock’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. BlackRock will notify the trustee of the redemption price promptly after the calculation thereof and the trustee shall have no duty to determine, or verify the calculation of, the redemption price.

Notice of any redemption will be mailed at least 10 days but not more than 60 days before the redemption date to each holder of notes to be redeemed. If we elect to redeem fewer than all the notes, the trustee will select the particular notes to be redeemed by such method that the trustee deems fair and appropriate; provided that if the notes are represented by one or more global securities, beneficial interests therein will be selected for redemption by Clearstream and Euroclear in accordance with their respective applicable procedures therefor; and provided, further, that no notes of a principal amount of €100,000 or less will be redeemed in part.

Any notice of redemption may, at BlackRock’s discretion, be subject to one or more conditions precedent, including completion of a corporate transaction. In such event, the related notice of redemption shall describe each such condition and, if applicable, shall state that, at BlackRock’s discretion, the date of redemption may be delayed until such time (including more than 60 days after the notice of redemption was given) as any or all such conditions shall be satisfied (or waived by BlackRock in its sole discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the date of redemption, or by the date of redemption so delayed.

The notes are also subject to redemption prior to maturity if certain changes in U.S. tax law occur. If such changes occur, the notes may be redeemed at a redemption price of 100% of their principal amount plus accrued and unpaid interest to the date of redemption. See “—Redemption for Tax Reasons.”

S-25

Unless BlackRock defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.

Priority

The notes and the Guarantee are obligations of BlackRock and BlackRock Finance, respectively, and not of their other subsidiaries. BlackRock is currently a holding company and, accordingly, substantially all of our operations are, or will be, conducted through our subsidiaries. As a result, our cash flow and ability to service debt, including the notes, depends upon the earnings of our subsidiaries. In addition, BlackRock and BlackRock Finance depend, or will depend, on the distribution of earnings, loans or other payments by their respective subsidiaries.

The other subsidiaries of BlackRock and BlackRock Finance are separate and distinct legal entities and have no obligation to pay any amounts due on the notes or to provide BlackRock or BlackRock Finance, as applicable, with funds for their payment obligations. In addition, any payment of dividends, distributions, loans or advances by BlackRock’s or BlackRock Finance’s subsidiaries to BlackRock or BlackRock Finance, as applicable, could be subject to statutory or contractual restrictions. Payments due to BlackRock or BlackRock Finance by their respective subsidiaries will also be contingent upon such subsidiaries’ earnings and business considerations.

The right of BlackRock or BlackRock Finance to receive any assets of any of their respective subsidiaries, as an equity holder of such subsidiaries, upon their liquidation or reorganization, and therefore the right of the holders of the notes to participate in those assets, would be structurally subordinated to the claims of that subsidiary’s creditors, including trade creditors. The notes do not restrict the ability of our subsidiaries to incur additional indebtedness. In addition, the notes are unsecured. Thus, even if BlackRock or BlackRock Finance were a creditor of any of their subsidiaries, their rights as a creditor would be effectively junior to any security interest in the assets of such subsidiaries and any indebtedness of such subsidiaries senior to that held by BlackRock or BlackRock Finance.

Payment of Additional Amounts

BlackRock will, subject to the exceptions and limitations set forth below, pay as additional interest on the notes such additional amounts as are necessary in order that the net payment by BlackRock or a paying agent of the principal, premium and interest with respect to the notes to a holder that is not a United States person (as defined herein), after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in the notes to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts will not apply:

S-26

Except as specifically provided under this heading “—Payment of Additional Amounts,” BlackRock will not be required to pay additional amounts in respect of any tax, assessment or other governmental charge. References in this prospectus supplement and the accompanying prospectus to any payment on the notes include the related payment of additional amounts, as applicable.

S-27

As used under this heading “—Payment of Additional Amounts” and under the heading “—Redemption for Tax Reasons,” the term “United States” means the United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S. federal income tax purposes), (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S. court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person.

Redemption for Tax Reasons

If, as a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after the date of this prospectus supplement, BlackRock becomes or, based upon a written opinion of independent counsel selected by BlackRock, will become obligated to pay additional amounts as described herein under the heading “—Payment of Additional Amounts” with respect to the notes, then BlackRock may at any time at its option redeem, in whole, but not in part, the notes on not less than 10 nor more than 60 days’ prior notice, at a redemption price equal to 100% of their principal amount, plus accrued and unpaid interest on the notes to be redeemed to, but excluding, the date of redemption.

Discharge, Defeasance and Covenant Defeasance

The provisions of the indenture described under “Description of Debt Securities—Discharge, Defeasance and Covenant Defeasance” in the accompanying prospectus apply to the notes.

However, any reference to “money and/or government obligations” shall refer to “money (in euros) and Federal Republic of Germany obligations.” “Federal Republic of Germany obligations” means (1) securities that are direct obligations of the Federal Republic of Germany for the payment of which its full faith and credit is pledged or (2) obligations of a person controlled or supervised by and acting as an agency or instrumentality of the Federal Republic of Germany, the payment of which is unconditionally guaranteed as a full faith and credit obligation by the Federal Republic of Germany, which, in either case under clauses (1) or (2) are not callable or redeemable at the option of the issuer thereof.

Book-Entry System; Delivery and Form

We have obtained the information in this section concerning Euroclear and Clearstream and their book-entry systems and procedures from sources we believe to be reliable. The description of the clearing systems in this section reflects our understanding of the rules and procedures of Euroclear and Clearstream as they are currently in effect. Those systems could change their rules and procedures at any time.

Global Clearance and Settlement

The notes will be issued in the form of one or more fully registered global notes (the “global notes”) and will be deposited with a common depositary for, and in respect of interests held through, Euroclear Bank SA/ NV (“Euroclear”) and Clearstream Banking, S.A. (“Clearstream”). Except as described herein, certificates will not be issued in exchange for beneficial interests in the global notes.

Except as set forth below, the global notes may be transferred, in whole and not in part, only to Euroclear or Clearstream or their respective nominees.

Beneficial interests in the global notes will be represented, and transfers of such beneficial interests will be effected, through accounts of financial institutions acting on behalf of beneficial owners as direct or indirect

S-28

participants in Euroclear or Clearstream. Those beneficial interests will be held in denominations of €100,000 and additional multiples of €1,000 in excess thereof. Investors may hold notes directly through Euroclear or Clearstream, if they are participants in such systems, or indirectly through organizations that are participants in such systems.

Owners of beneficial interests in the global notes will not be entitled to have notes registered in their names, and will not receive or be entitled to receive physical delivery of notes in definitive form. Except as provided below, beneficial owners will not be considered the owners or holders of the notes under the indenture, including for purposes of receiving any reports delivered by BlackRock or the trustee pursuant to the indenture. Accordingly, each beneficial owner must rely on the procedures of the clearing systems and, if such person is not a participant of the clearing systems, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the indenture. Under existing industry practices, if BlackRock requests any action of holders or a beneficial owner desires to give or take any action a holder is entitled to give or take under the indenture, the clearing systems would authorize their participants holding the relevant beneficial interests to give or take action and the participants would authorize beneficial owners owning through the participants to give or take such action or would otherwise act upon the instructions of beneficial owners. Conveyance of notices and other communications by the clearing systems to their participants, by the participants to indirect participants and by the participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in certificated form. These limits and laws may impair the ability to transfer beneficial interests in global notes.

Persons that are not Euroclear or Clearstream participants may beneficially own notes held by the common depositary for Euroclear and Clearstream only through direct or indirect participants in Euroclear and Clearstream. So long as the common depositary for Euroclear and Clearstream is the registered owner of the global note, the common depositary for all purposes will be considered the sole holder of the notes represented by the global note under the indenture and the global note.

The policies of Clearstream and Euroclear will govern payments, transfers, exchanges and other matters relating to an investor’s interest in the notes held by them. We have no responsibility for any aspect of the records kept by Clearstream or Euroclear or any of their direct or indirect participants. We also do not supervise these systems in any way.

Euroclear

Euroclear advises that it was created in 1968 to hold securities for its participants (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing, and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.A. (the “Euroclear Operator”), under contract with Euroclear Clearance Systems, S.C., a Belgian cooperative corporation (the “Cooperative”).

All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of the Euroclear System, and

S-29

applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants and has no record of or relationship with persons holding through Euroclear Participants.

Distributions with respect to the notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions, to the extent received by its depositary.

Euroclear further advises that investors that acquire, hold and transfer interests in the notes by book-entry through accounts with the Euroclear Operator or any other securities intermediary are subject to the laws and contractual provisions governing their relationship with their intermediary, as well as the laws and contractual provisions governing the relationship between such an intermediary and each other intermediary, if any, standing between themselves and the global notes.

The Euroclear Operator advises as follows: under Belgian law, investors that are credited with securities on the records of the Euroclear Operator have a co-property right in the fungible pool of interests in securities on deposit with the Euroclear Operator in an amount equal to the amount of interests in securities credited to their accounts. In the event of the insolvency of the Euroclear Operator, Euroclear Participants would have a right under Belgian law to the return of the amount and type of interests in securities credited to their accounts with the Euroclear Operator. If the Euroclear Operator did not have a sufficient amount of interests in securities on deposit of a particular type to cover the claims of all Participants credited with such interests in securities on the Euroclear Operator’s records, all Participants having an amount of interests in securities of such type credited to their accounts with the Euroclear Operator would have the right under Belgian law to the return of their pro rata share of the amount of interests in securities actually on deposit.

Under Belgian law, the Euroclear Operator is required to pass on the benefits of ownership in any interests in securities on deposit with it (such as dividends, voting rights and other entitlements) to any person credited with such interests in securities on its records.

Clearstream

Clearstream advises that it is incorporated under the laws of Luxembourg and licensed as a bank and professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Customers”) and facilitates the clearance and settlement of securities transactions between Clearstream Customers through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Customers, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic securities markets in over 30 countries through established depository and custodial relationships. Clearstream has established an electronic bridge with the Euroclear Operator to facilitate the settlement of trades between Euroclear and Clearstream. As a registered bank in Luxembourg, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters. Clearstream’s U.S. customers are limited to securities brokers and dealers and banks. Indirect access to Clearstream is also available to other institutions, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Customer, either directly or indirectly.

Distributions with respect to the notes held through Clearstream will be credited to cash accounts of Clearstream Customers in accordance with its rules and procedures.

S-30

Euroclear and Clearstream Arrangements

So long as Euroclear or Clearstream or their nominee or their common depositary is the registered holder of the global notes, Euroclear, Clearstream or such nominee, as the case may be, will be considered the sole owner or holder of the notes represented by such global notes for all purposes under the indenture and the notes. Payments of principal, premium and interest in respect of the global notes will be made to Euroclear, Clearstream or such nominee, as the case may be, as registered holder thereof. None of BlackRock, BlackRock Finance, the trustee, any underwriter and any affiliate of any of the above or any person by whom any of the above is controlled (as such term is defined in the Securities Act of 1933, as amended (the “Securities Act”)) will have any responsibility or liability for any records relating to or payments made on account of beneficial ownership interests in the global notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

Distributions of principal, premium and interest with respect to the global notes will be credited in euro to the extent received by Euroclear or Clearstream from the paying agent to the cash accounts of Euroclear or Clearstream customers in accordance with the relevant system’s rules and procedures.

Because Euroclear and Clearstream can only act on behalf of participants, who in turn act on behalf of indirect participants, the ability of a person having an interest in the global notes to pledge such interest to persons or entities that do not participate in the relevant clearing system, or otherwise take actions in respect of such interest, may be affected by the lack of a physical certificate in respect of such interest.

Initial Settlement

We understand that investors that hold their notes through Euroclear or Clearstream accounts will follow the settlement procedures that are applicable to conventional eurobonds in registered form. Subject to applicable procedures of Euroclear and Clearstream, notes will be credited to the securities custody accounts of Clearstream and Euroclear participants on the business day following the settlement date, for value on the settlement date.

Secondary Market Trading

Because the purchaser determines the place of delivery, it is important to establish at the time of trading of any notes where both the purchaser’s and seller’s accounts are located to ensure that settlement can be made on the desired value date.

We understand that secondary market trading between Euroclear and/or Clearstream participants will occur in the ordinary way following the applicable rules and operating procedures of Euroclear and Clearstream. Secondary market trading will be settled using procedures applicable to conventional eurobonds in registered form.

You should be aware that investors will only be able to make and receive deliveries, payments and other communications involving the notes through Euroclear and Clearstream on days when those systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States.

In addition, because of time-zone differences, there may be problems with completing transactions involving Euroclear and Clearstream on the same business day as in the United States. U.S. investors who wish to transfer their interests in the notes, or to make or receive a payment or delivery of the notes, on a particular day, may find that the transactions will not be performed until the next business day in Brussels or Luxembourg, depending on whether Euroclear or Clearstream is used.

Euroclear or Clearstream will credit payments to the cash accounts of Euroclear Participants or Clearstream Customers, as applicable, in accordance with the relevant system’s rules and procedures, to the extent received by its depositary. The Euroclear Operator or Clearstream, as the case may be, will take any other action permitted to be taken by a holder under the indenture on behalf of a Euroclear Participant or Clearstream Customer only in accordance with its relevant rules and procedures.

S-31

Euroclear and Clearstream have agreed to the foregoing procedures in order to facilitate transfers of the notes among participants of Euroclear and Clearstream. However, they are under no obligation to perform or continue to perform those procedures, and they may discontinue those procedures at any time.

Certificated Notes

Subject to certain conditions, the notes represented by the global notes are exchangeable for certificated notes in definitive form of like tenor in minimum denominations of €100,000 principal amount and multiples of €1,000 in excess thereof if:

In all cases, certificated notes delivered in exchange for any global note will be registered in the names, and issued in any approved denominations, requested by or on behalf of the depositary (in accordance with its customary procedures).

Payments (including principal, premium and interest) and transfers with respect to notes in certificated form may be executed at the office or agency maintained for such purpose in London (initially the office of the paying agent maintained for such purpose) or, with respect to payments of interest, at BlackRock’s option, by check mailed to the holders thereof at the respective addresses set forth in the register of holders of the notes, provided that all payments of interest on notes in certificated form, for which the holders thereof have given wire transfer instructions to the paying agent at least 15 calendar days prior to the applicable interest payment date, will be required to be made by wire transfer of immediately available funds to the accounts specified by the holders thereof. No service charge will be made for any registration of transfer, but payment of a sum sufficient to cover any tax or governmental charge payable in connection with that registration may be required.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of U.S. federal income tax considerations generally applicable to the ownership and disposition of the notes. This summary is based on the Code, U.S. Treasury Regulations promulgated thereunder (“Treasury Regulations”), judicial decisions, published positions of the Internal Revenue Service (the “IRS”) and other applicable authorities, all as in effect as of the date hereof and all of which are subject to change or differing interpretations (possibly with retroactive effect). This summary does not address specific tax consequences to particular persons in light of their individual circumstances, such as insurance companies, banks or other financial institutions, broker-dealers, tax-exempt organizations, regulated investment companies, persons holding the notes as part of a straddle, hedge, conversion transaction or other integrated investment, partnerships (or other entities or arrangements treated as partnerships for U.S. federal income tax purposes) and their partners, “controlled foreign corporations,” “passive foreign investment companies,” certain former citizens and former long-term residents of the United States. In addition, this summary does not address any aspects of the Medicare contribution tax on net investment income, alternative minimum taxes, U.S. federal estate or gift tax considerations, state, local, or foreign tax laws or special timing rules prescribed under section 451(b) of the Code. This summary deals only with notes held as capital assets (generally, assets held for investment) by a holder that acquires the notes upon original issuance at their initial offering price.

Prospective purchasers of the notes should consult their tax advisors concerning the U.S. federal income tax consequences to them of acquiring, owning and disposing of the notes, as well as the application of other U.S. federal tax laws and state, local and foreign tax laws.

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of notes who, for U.S. federal income tax purposes, is (1) a citizen or individual resident of the United States, (2) a corporation, or other entity that is treated as a corporation for U.S. federal income tax purposes, that is created or organized in or under the laws of the United States, or any state thereof or the District of Columbia, (3) an estate whose income is subject to U.S. federal income taxation regardless of its source, or (4) a trust (i) if a U.S. court can exercise primary supervision over the trust’s administration and one or more U.S. persons are authorized to control all substantial decisions of the trust, or (ii) that validly elects to be treated as a United States person for U.S. federal income tax purposes.

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of notes that is not a U.S. Holder and is not a partnership for U.S. federal income tax purposes.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) beneficially owns the notes, the treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. A holder of the notes that is a partnership and partners in such partnership should consult their tax advisors as to the tax consequences to them of purchasing, owning and disposing of the notes.

Consequences to U.S. Holders

Payments of Interest

A U.S. Holder that uses the cash method of tax accounting will be required to include in ordinary income the U.S. dollar value of the euro-denominated interest payment on a note based on the spot rate of exchange on the date of receipt. No foreign currency exchange gain or loss will be recognized with respect to the receipt of such payment (other than foreign currency exchange gain or loss realized on the disposition of the euros so received; see “—Transactions in Euros,” below). It is anticipated, and this discussion assumes, that the notes will be issued with less than a de minimis amount of original issue discount.

A U.S. Holder that uses the accrual method of tax accounting will accrue interest income on a note in euros and translate the amount accrued into U.S. dollars based on:

S-33

Such election must be applied consistently by the U.S. Holder to all debt instruments from year to year and can be changed only with the consent of the IRS. A U.S. Holder that uses the accrual method of tax accounting will recognize foreign currency exchange gain or loss on the receipt of an interest payment equal to the difference between (i) the value of the euros received as interest, as translated into U.S. dollars using the spot rate of exchange on the date of receipt and (ii) the U.S. dollar amount previously included in income with respect to such payment. Such foreign currency exchange gain or loss will be treated as ordinary income or loss but will generally not be treated as an adjustment to interest income received on the notes.

Disposition

Upon the sale, exchange, retirement at maturity, redemption or other taxable disposition of a note (collectively, a “Disposition”), except as noted below with respect to foreign currency exchange gain or loss, a U.S. Holder will generally recognize capital gain or loss equal to the difference between the amount realized by such U.S. Holder (except to the extent such amount is attributable to accrued but unpaid interest, which will be treated as ordinary interest income if such interest has not been previously included in income) and such U.S. Holder’s adjusted tax basis in the note.

Subject to the discussion below regarding notes that are traded on an established securities market, the adjusted tax basis of a note to a U.S. Holder will generally be the U.S. dollar value of the euro purchase price calculated at the spot rate of exchange on the date of purchase, and the amount realized by a U.S. Holder upon the Disposition of a note will generally be the U.S. dollar value of the euros received calculated at the spot rate of exchange on the date of Disposition. If the notes are traded on an established securities market, a U.S. Holder that uses the cash method of tax accounting, and a U.S. Holder that uses the accrual method of tax accounting if it so elects, will determine the U.S. dollar values of its adjusted tax basis in the note and the amount realized on the Disposition of a note by translating euro amounts at the spot rate of exchange on the settlement date of the purchase or the Disposition, respectively. The election available to accrual basis U.S. Holders discussed above must be applied consistently by the U.S. Holder to all debt instruments from year to year and can be changed only with the consent of the IRS.

Any capital gain or loss will be long-term capital gain or loss if the U.S. Holder’s holding period for the notes exceeds one year on the date of Disposition. Long-term capital gains recognized by non-corporate U.S. Holders are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Gain or loss recognized by a U.S. Holder on a Disposition of a note will generally be treated as ordinary income or loss to the extent that the gain or loss is attributable to changes in the euro to U.S. dollar exchange rate during the period in which the U.S. Holder held such note. Such foreign currency exchange gain or loss will equal the difference between the U.S. dollar value of the euro purchase price calculated at the spot rate of exchange on the date (1) the note is disposed of (or the spot rate on the settlement date, if applicable) and (2) of purchase (or the spot rate on the settlement date, if applicable). The recognition of such foreign currency exchange gain or loss will be limited to the amount of overall gain or loss realized on the Disposition of a note.

Transactions in Euros

Euros received as interest on, or on a Disposition of, a note will have a tax basis equal to their U.S. dollar value determined using the spot rate of exchange on the date such interest or such proceeds from Disposition are received. The amount of gain or loss recognized on a subsequent sale or other disposition of such euros will be equal to the difference between (1) the amount of U.S. dollars, or the fair market value in U.S. dollars of the

S-34

other property received in such sale or other disposition, and (2) the U.S. Holder’s adjusted tax basis in such euros. As discussed above, if the notes are traded on an established securities market, a cash basis U.S. Holder (or an electing accrual basis U.S. Holder) will determine the U.S. dollar value of the euros by translating the euros received at the spot rate of exchange on the settlement date of the purchase or the Disposition. A U.S. Holder that purchases a note with previously owned euros will generally recognize gain or loss in an amount equal to the difference, if any, between such U.S. Holder’s adjusted tax basis in such euros and the U.S. dollar fair market value of such note on the date of purchase.

Any such gain or loss will generally be ordinary income or loss and will not be treated as interest income or expense. The conversion of U.S. dollars to euros and the immediate use of such euros to purchase a note will generally not result in any exchange gain or loss for a U.S. Holder.

Reportable Transactions

Treasury Regulations require the reporting to the IRS of certain foreign currency transactions (such as the receipt or accrual of interest on, or the disposition of, a note or foreign currency received in respect of a note) if such transactions give rise to losses in excess of a certain minimum amount. Each U.S. Holder should consult its tax advisor to determine its reporting obligations, if any, with respect to an investment in the notes, including any requirement to file IRS Form 8886 (Reportable Transaction Disclosure Statement).

Consequences to Non-U.S. Holders

Payments of Interest

Subject to the discussions below concerning the Foreign Account Tax Compliance Act, a Non-U.S. Holder will generally not be subject to U.S. federal income or withholding tax on the receipt of payments of interest on the notes; provided that such interest is not effectively connected with the conduct of a trade or business within the United States by the Non-U.S. Holder (or, if required under an applicable treaty, such interest is not attributable to a permanent establishment or fixed base maintained within the United States by the Non-U.S. Holder) and:

Alternatively, a Non-U.S. Holder that cannot satisfy the above requirements will generally be exempt from U.S. federal withholding tax with respect to interest on the notes if the holder establishes that such interest is not subject to withholding tax because it is effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States (generally, by providing an IRS Form W-8ECI). To the extent that such interest is effectively connected with the Non-U.S. holder’s conduct of a trade or business (and, in the case of certain tax treaties, is attributable to a permanent establishment or fixed base within the United States), the Non-U.S. Holder will be subject to U.S. federal income tax on a net basis and, if it is a foreign corporation, may be subject to a 30% U.S. branch profits tax (or lower applicable treaty rate).

If a Non-U.S. Holder does not qualify for any of the exemptions described above, the Non-U.S. Holder will generally be subject to U.S. federal withholding tax on payments of stated interest, currently imposed at 30%. Under certain income tax treaties, the U.S. federal withholding rate on payments of interest may be reduced or

S-35

eliminated, provided the Non-U.S. Holder complies with the applicable certification requirements (generally, by providing a properly completed IRS Form W-8BEN-E or W-8BEN). We will not pay additional amounts to Non-U.S. Holders in respect of any amounts withheld.

Disposition

A Non-U.S. Holder will generally not be subject to U.S. federal income or withholding tax on a Disposition of a note (other than any amount attributable to accrued but unpaid interest, which will be taxable in the manner described above under “—Payments of Interest”), unless:

If the first exception applies, the Non-U.S. Holder will generally be subject to U.S. federal income tax on a net basis and, if it is a foreign corporation, may be subject to a 30% U.S. branch profits tax (or lower applicable treaty rate). If the second exception applies, the Non-U.S. Holder will generally be subject to U.S. federal income tax at a rate of 30% (or at a reduced rate under an applicable income tax treaty) on the amount by which capital gains allocable to U.S. sources (including gains from the sale, exchange, retirement or other disposition of the notes) exceed capital losses allocable to U.S. sources.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code and the Treasury regulations and administrative guidance promulgated thereunder (commonly referred to as the “Foreign Account Tax Compliance Act” or “FATCA”) generally impose withholding at a rate of 30% in certain circumstances on interest payable on notes held by or through certain financial institutions (including investment funds), unless such institution (i) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons or by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, or (ii) if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which notes are held will affect the determination of whether such withholding is required. Similarly, interest payable on notes held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exemptions will generally be subject to withholding at a rate of 30%, unless such entity either (i) certifies that such entity does not have any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners,” which we or the withholding agent will in turn provide to the United States Department of the Treasury. We will not pay additional amounts to Non-U.S. Holders in respect of any amounts withheld. Each prospective investor should consult its tax advisor regarding the possible implications of these rules on an investment in the notes.

S-36

CERTAIN EUROPEAN UNION TAX CONSIDERATIONS

The Proposed Financial Transactions Tax (‘‘FTT’’)

Ten Member States are proposing to implement a financial transaction tax (“FTT”). In its proposed form, the FTT applies to certain transactions in financial instruments involving financial institutions where at least one party to which is located in a participating Member State, or where the financial instrument is issued in a participating Member State. The FTT is currently set to be levied at a minimum rate of 0.1% on all transactions other than derivatives which are to be taxed at a minimum rate of 0.01%. The FTT can be charged on both counterparties, depending on the nature of their activities, their location, and the subject matter of the transaction. The current proposals therefore do impact on certain financial institutions located outside the ten participating Member States, as well as certain financial institutions located outside the European Union.

Any changes to the current framework of the taxation of financial transactions within the European Union, including changes contemplated by the proposed FTT, could apply to certain dealings in the notes. Additionally, the proposed FTT contains certain anti-avoidance rules which may restrict our and a holder of the notes’ ability to mitigate the impact of these charges. It should be noted that a similar tax has already been introduced in France and Italy and other Member States may introduce a similar tax. Participating Member States which implement the FTT, such as France and Italy, are expected to repeal any similar taxes with effect from the implementation of the FTT.

The FTT proposal remains subject to negotiation between the participating Member States and the scope of such tax is uncertain. Such proposal remains subject to change until a final approval and it may therefore be altered prior to any implementation, the timing of which remains unclear. Additional Member States may decide to participate and/or certain of the participating Member States may decide to withdraw.

You should consult your own tax advisor regarding the consequences of the FTT that could be associated with subscribing for, purchasing, holding and disposing of the notes.

UNDERWRITING

BNP PARIBAS, Deutsche Bank AG, London Branch and J.P. Morgan Securities plc are acting as the representatives of each of the underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among BlackRock, BlackRock Finance and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from BlackRock, the principal amount of notes set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the notes sold under the underwriting agreement if any of these notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriter may be increased or the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters and their controlling persons against certain liabilities in connection with this offering, including liabilities under the Securities Act or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the notes, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

To the extent that any underwriters that are not U.S. registered broker-dealers intend to effect any sales of the notes in the United States, they will only do so through one or more U.S. registered broker dealer affiliates in compliance with applicable law.

S-38

Commissions and Discounts

The representatives have advised us that the underwriters propose initially to offer the notes to the public at the public offering price set forth on the cover page of this prospectus supplement and may offer the notes to certain dealers at such prices less concessions not in excess of 0.250% of the principal amount of the notes. The underwriters may allow, and the dealers may reallow, a discount on the notes to other dealers not in excess of 0.125% the principal amount of the notes. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The following table shows the public offering price, underwriting discount and proceeds before expenses to BlackRock.

The expenses of the offering, not including the underwriting discount, are estimated at $2.3 million and are payable by us.

Price Stabilization and Penalty Bids

In connection with the offering of the notes, the Stabilizing Manager (or persons acting on behalf the Stabilizing Manager) may purchase and sell the notes in the open market. These transactions may include overallotment, syndicate covering transactions and stabilizing transactions. Overallotment involves syndicate sales of notes in excess of the principal amount of notes to be purchased by the underwriters in the offering, which creates a syndicate short position. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing transactions consist of certain bids or purchases of notes made for the purpose of preventing or retarding a decline in the market prices of the notes while the offering is in progress. There is no assurance that the Stabilizing Manager (or persons acting on behalf of the Stabilizing Manager) will undertake stabilization action. Such stabilization, if begun, must be brought to an end after a limited period. Any stabilization action or overallotment must be conducted by the Stabilizing Manager (or person(s) acting on behalf of the Stabilizing Manager) in accordance with all applicable laws and rules.

The underwriters also may impose a penalty bid. Penalty bids permit the underwriters to reclaim a selling concession from a syndicate member when the underwriters, in covering syndicate short positions or making stabilizing purchases, repurchase notes originally sold by that syndicate member.

Any of these activities may have the effect of preventing or retarding a decline in the market prices of the notes. They may also cause the prices of the notes to be higher than the prices that otherwise would exist in the open market in the absence of these transactions. The Stabilizing Manager may conduct these transactions in the over-the-counter market or otherwise. If the Stabilizing Manager commences any of these transactions, they may discontinue them at any time.

The notes are a new issue of securities, and there is currently no established trading market. We intend to apply to list the notes on the NYSE to begin within 30 days after the original issue date. Currently there is no public market for the notes. The listing application will be subject to approval by the NYSE. If such a listing is obtained, we have no obligation to maintain such listing, and we may delist the notes at any time. Although the underwriters have advised us that certain of them intend to make a market in the notes, they are not obligated to

S-39

do so. The underwriters may discontinue any market making in the notes at any time without notice in their sole discretion. Therefore, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

Other Relationships

The underwriters and their affiliates have provided, and may in the future provide, investment banking, commercial lending, financial advisory and other services for us. The underwriters have received customary fees and expenses for these services. In particular, certain of the underwriters and/or their affiliates are dealers under BlackRock’s commercial paper program. Certain of the underwriters or their affiliates may own a portion of our outstanding 1.25% Notes due 2025, which may be repaid using a portion of the net proceeds from this offering. In addition, certain of the underwriters and/or their affiliates are lenders under BlackRock’s $5.4 billion revolving credit facility maturing in March 2029.

In addition, in the ordinary course of their business activities, the underwriters and their 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. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or

their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions that consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Conflicts of Interest

Certain of the underwriters or their affiliates hold some of our outstanding 1.25% Notes due 2025, which we may repay using the net proceeds of this offering. See “Use of Proceeds” in this prospectus supplement. In such event, it is possible that one or more of the underwriters or their affiliates could receive 5% or more of the net proceeds of this offering, and, in that case, such underwriter would be deemed to have a conflict of interest under FINRA Rule 5121 (Public Offerings of Securities with Conflicts of Interest). Accordingly, this offering is being made in compliance with FINRA Rule 5121 and no underwriter with a conflict of interest under FINRA Rule 5121 will make sales in this offering to any discretionary account without the prior written approval of the customer. The appointment of a “qualified independent underwriter” is not required in connection with this offering because the notes are “investment grade rated” (as defined in FINRA Rule 5121).

Delayed Settlement

We expect that delivery of the notes will be made to investors on or about the seventh business day following the date of the pricing of the notes (“T+7”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to a trade expressly agree otherwise. Accordingly, investors who wish to trade notes prior to one business day before delivery may be required, by virtue of the fact that the notes initially will settle in T+7, to specify alternative settlement arrangements to prevent a failed settlement. Investors who wish to trade the notes prior to one business day before their date of delivery hereunder should consult their advisors.

S-40

Selling Restrictions

Canada

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement (including any amendment thereto) contains a misrepresentation; provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (“NI 33-105”), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

European Economic Area

The notes may not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes:

Consequently, no key information document required by the PRIIPs Regulation for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of notes in any member state of the EEA or the United Kingdom will be made pursuant to an exemption under the Prospectus Regulation from the requirement to publish a prospectus for offers of the notes. This prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the Prospectus Regulation.

United Kingdom

The notes may not be offered, sold or otherwise made available to any retail investor in the United Kingdom. For the purposes of this provision:

S-41

Consequently, no key information document required by the UK PRIIPs Regulation for offering or selling the notes or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the UK PRIIPs Regulation.

The communication of this prospectus supplement and the accompanying prospectus is only being distributed to and is only directed at (i) persons who are outside the United Kingdom or (ii) investment professionals falling within Article 19(5) of the Order or (iii) high net worth companies, and other persons to whom it may lawfully be communicated, falling within Article 49(2)(a) to (e) of the Order (all such persons falling within (i)-(iii) together being referred to as “relevant persons”). The notes will only be available to, and any invitation, offer or agreement to subscribe, purchase or otherwise acquire such notes will be engaged in only with, relevant persons. Any person who is not a relevant person should not act or rely on this prospectus supplement and the accompanying prospectus, or any of their contents.

Each underwriter has represented, warranted and agreed that: (a) it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the FSMA) received by it in connection with the issue or sale of the notes which are the subject of the offering contemplated in this prospectus supplement and the accompanying prospectus in circumstances in which Section 21(1) of the FSMA does not apply to BlackRock; and (b) it has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the notes in, from or otherwise involving the United Kingdom.

The notes have not been and will not be offered or sold in Hong Kong by means of any document other than (i) in circumstances which do not constitute an offer to the public within the meaning of the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32 of the Laws of Hong Kong) (the “C(WUMP)O”), or (ii) to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571 of the Laws of Hong Kong) (the “SFO”) and any rules made thereunder, or (iii) in other circumstances which do not result in the document being a “prospectus” within the meaning of the C(WUMP)O. No advertisement, invitation or document relating to the notes have been or will be issued or may be in the possession of any person for the purpose of issue (in each case, whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public of Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” within the meaning of the SFO and any rules made thereunder.

S-42

offered by this prospectus supplement have not been and will not be offered or sold, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan (meaning any person resident in Japan, including any corporation or other entity organized under the laws of Japan), or to others for re-offering or resale, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the FIEA and any other applicable laws, regulations and ministerial guidelines of Japan in effect at the relevant time.

DESCRIPTION OF DEBT SECURITIES

In this “Description of Debt Securities.” section, references to “BlackRock” refer to BlackRock, Inc. and its successors, as the issuer of debt securities that may be offered hereunder. References to the “BlackRock Finance” refer to BlackRock Finance, Inc. and its successors.

BlackRock 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. BlackRock Finance may, from time to time, fully and unconditionally guarantee the debt securities of BlackRock. See “—Guarantee of Debt Securities.”

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, BlackRock’s debt securities will be issued in one or more series under the indenture (the “indenture”) to be entered into by BlackRock, BlackRock Finance and The Bank of New York Mellon, as trustee. A form of indenture is filed as an exhibit to the registration statement of which this prospectus forms a part, and any supplemental indenture will be filed as an exhibit to a document incorporated by reference herein, in connection with the issuance of any new series of debt securities offered and sold hereunder. In this “Description of Debt Securities” section, we refer to the indenture, as amended and supplemented by each supplemental indenture applicable to a series of debt securities issued thereunder and offered hereby, as an “indenture.” We urge you to read the indenture and relevant supplemental indentures because these documents, and not the summary below, will define your rights as a holder of debt securities. Capitalized terms used in the summary will have the meanings specified in the indenture. The terms of the debt securities will include those that will be set forth in the indenture and those made a part of the indenture by the Trust Indenture Act of 1939 (the “TIA”). You should read the summary below, any accompanying prospectus supplement and the provisions of the indenture in their entirety before investing in BlackRock’s debt securities. The indenture will be governed by the laws of the State of New York.

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 BlackRock may offer will contain the specific terms of the debt securities. These terms may include, among others, the following:

8

General

BlackRock may issue the debt securities in one or more series with the same or various maturities, at par or at a premium or with original issue discount. Unless we inform you otherwise in a prospectus supplement, BlackRock 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.

9

We will describe in an accompanying prospectus supplement any other special considerations for any debt securities 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.

Unless otherwise specified in an accompanying prospectus supplement, the debt securities will be issued in fully registered form without coupons and in 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.

Guarantee of Debt Securities

To the extent specified in an accompanying prospectus supplement, BlackRock Finance may provide a full and unconditional guarantee of any debt securities issued by BlackRock (in each case, a “Guarantee”) pursuant to the indenture. Where BlackRock Finance has provided a Guarantee, if BlackRock defaults in the payment of the principal of, or premium, if any, or interest on, such debt securities when and as the same shall become due, whether upon maturity, acceleration, or otherwise, or any other amounts owed under the indenture, without the necessity of action by the trustee or any holder of such debt securities, BlackRock Finance shall be required promptly and fully to make such payment.

Upon the occurrence of the below events, any such Guarantee will be automatically and unconditionally released and discharged, BlackRock Finance will be released from all obligations under the indenture in its capacity as guarantor, and no further action of BlackRock, BlackRock Finance or the trustee will be required for the release of the Guarantee:

10

“BlackRock Finance Notes” means as of any time of determination, the (i) 1.250% Notes due 2025, (ii) 3.200% Notes due 2027, (iii) 3.250% Notes due 2029, (iv) 2.400% Notes due 2030, (v) 1.900% Notes due 2031, (vi) 2.10% Notes due 2032 and (vii) the 4.750% Notes due 2033, in each case, previously issued by BlackRock Finance, and outstanding as of such time. BlackRock currently guarantees the BlackRock Finance Notes.

BlackRock Finance currently guarantees BlackRock’s (i) 4.60% Notes due 2027, (ii) 4.70% Notes due 2029, (iii) 5.00% Notes due 2034, (iv) 4.90% Notes due 2035, (v) 5.25% Notes due 2054 and (vi) 5.35% Notes due 2055.

Consolidation, Merger, Sale of Assets and Other Transactions

Neither BlackRock nor BlackRock Finance may consolidate with or merge into another person or convey, transfer or lease their respective properties and assets substantially as an entirety to any other person (other than a direct or indirect wholly owned subsidiary of BlackRock or BlackRock Finance), and neither BlackRock nor BlackRock Finance may permit any person (other than a direct or indirect wholly owned subsidiary of BlackRock or BlackRock Finance) consolidate with or merge into BlackRock or BlackRock Finance or convey, transfer or lease its properties substantially as an entirety to BlackRock or BlackRock Finance, as the case may be, unless:

Modification of Indenture

Under the indenture, BlackRock and the trustee may supplement the indenture for certain purposes which would not adversely affect the interests of the holders of debt securities of a series in any material respect without the consent of those holders. Under the indenture, the rights of the holders may be modified through a supplemental indenture if the holders of at least a majority in aggregate principal amount of the outstanding debt securities of all series affected by the modification (voting as one class) consent to it; provided that any such supplemental indenture that releases (other than in accordance with the terms of the indenture or any series of debt securities) the Guarantee shall require the consent of the holders of at least 66²⁄₃% in aggregate principal amount of the debt securities of each series affected by such supplemental indenture. However, no modification of the maturity date, principal or interest payment terms or premium payable on redemption, no modification of the currency for payment, no impairment of the right to sue for the enforcement of payment at the maturity of the debt security, no modification of any conversion rights, no modification reducing the percentage required for any such supplemental indenture or the percentage required for the waiver of compliance with certain provisions of the

11

indenture or certain defaults and no modification of the foregoing provisions or any other provisions relating to the waiver of past defaults or the waiver of certain covenants, is effective against any holder without its consent.

Events of Default, Notice and Waiver

Unless an accompanying prospectus supplement states otherwise, the following shall constitute “Events of Default” under the indenture with respect to each series of debt securities:

If an Event of Default with respect to any debt securities of any series outstanding under the indenture shall occur and be continuing, the trustee or the holders of at least 33% in aggregate principal amount of the debt securities of that series outstanding may declare, by notice as provided in the indenture, the principal amount (or such lesser amount as may be provided for in the debt securities of that series) of all the debt securities of that series outstanding to be due and payable immediately; provided that, in the case of an Event of Default involving certain events of bankruptcy, insolvency or reorganization, acceleration is automatic; and, provided further, that after such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal, have been cured or waived. Upon the acceleration of the maturity of original issue discount securities, an amount less than the principal amount thereof will become due and payable. Reference is made to the prospectus supplement relating to any original issue discount securities for the particular provisions relating to acceleration of maturity thereof.

Any past default under the indenture with respect to debt securities of any series, and any Event of Default arising therefrom, may be waived by the holders of a majority in principal amount of all debt securities of such series outstanding under the indenture, except in the case of (i) default in the payment of the principal of (or premium, if any) or interest on any debt securities of such series or (ii) default in respect of a covenant or provision which may not be amended or modified without the consent of the holder of each outstanding debt security of such series affected.

The trustee, subject to its duties during default to act with the required standard of care, may require indemnification by the holders of the debt securities of any series with respect to which a default has occurred before proceeding to exercise any right or power under the indenture at the request of the holders of the debt

12

securities of such series. Subject to such right of indemnification and to certain other limitations, the holders of a majority in principal amount of the outstanding debt securities of any series under the indenture may direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee with respect to the debt securities of such series, provided that such direction shall not be in conflict with any rule of law or with the indenture or result in the incurrence of liability by the trustee and the trustee may take any other action deemed proper by the trustee which is not inconsistent with such direction.

No holder of a debt security of any series may institute any action against us under the indenture (except actions for payment of overdue principal of (and premium, if any) or interest on such debt security or for the conversion or exchange of such debt security in accordance with its terms) unless (i) the holder has given to the trustee written notice of an Event of Default and of the continuance thereof with respect to the debt securities of such series specifying an Event of Default, as required under the indenture, (ii) the holders of at least 33% in aggregate principal amount of the debt securities of that series then outstanding under the indenture shall have requested the trustee to institute such action and offered to the trustee reasonable indemnity or security satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request, (iii) the trustee shall not have instituted such action within 60 days of such request and (iv) no direction inconsistent with such written request has been given to the trustee during such 60-day period by the holders of a majority in principal amount of the debt securities of that series.

BlackRock is required to furnish annually to the trustee statements as to BlackRock’s compliance with all conditions and covenants under the indenture.

Payment and Transfer and Exchange

BlackRock will pay principal, interest and any premium on fully registered securities at the place or places designated by BlackRock for such purposes. BlackRock will make payment to the persons in whose names the debt securities are registered on the close of business on the record date for such interest. Any other payments will be made as set forth in the applicable prospectus supplement.

Holders may transfer or exchange fully registered securities at any office or agency maintained by BlackRock for such purposes, without the payment of any service charge except for any tax or governmental charge BlackRock is required to pay in connection with a transfer or exchange.

Upon surrender for registration of transfer of any security of any series in accordance with the terms of the indenture, BlackRock shall execute, and the trustee shall authenticate and deliver or make available for delivery, in the name of the designated transferee or transferees, one or more new securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount.

If the securities of any series are to be redeemed, BlackRock is not required to:

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

13

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.

Discharge, Defeasance and Covenant Defeasance

BlackRock may discharge or defease BlackRock’s and BlackRock Finance’s, as the case may be, obligations under the indenture (and the related Guarantee) as set forth below, unless otherwise indicated in the applicable prospectus supplement.

BlackRock may discharge certain obligations to holders of any series of debt securities issued under the indenture that have not already been delivered to the trustee for cancellation or which have either become due and payable or by their terms will become due and payable within one year (or are scheduled for redemption within one year) by irrevocably depositing with the trustee money and/or government obligations which through the payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay and discharge the entire indebtedness on such debt securities for principal (and premium, if any) and interest to the date of such deposit (in the case of debt securities which have become due and payable) or to the stated maturity or redemption date, as the case may be, and BlackRock has paid all other sums payable under the applicable indenture.

BlackRock may elect either (i) to defease and be discharged from any and all obligations of BlackRock and BlackRock Finance with respect to the debt securities of or within any series and any related obligations under the Guarantee (except as otherwise provided in the indenture) (“defeasance”) or (ii) to be released from BlackRock’s and BlackRock Finance’s obligations with respect to certain covenants applicable to the debt securities of or within any series (“covenant defeasance”), upon the deposit with the trustee, in trust for such purpose, of money and/or government obligations which through the payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay the principal of (and premium, if any) or interest on such debt securities to maturity or redemption, as the case may be, and any mandatory sinking fund or analogous payments thereon. As a condition to defeasance or covenant defeasance, BlackRock must deliver to the trustee an officer’s certificate and an opinion of counsel, each stating that all conditions precedent with respect to such defeasance or covenant defeasance have been complied with.

BlackRock may exercise its defeasance option with respect to such debt securities notwithstanding BlackRock’s prior exercise of its covenant defeasance option.

Conversion or Exchange Rights

The applicable prospectus supplement will describe the terms, if any, on which a series of debt securities may be convertible into or exchangeable for securities or property of another person. These terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at BlackRock’s option. These provisions may allow or require the number or amount of securities to be received by the holders of such series of debt securities to be adjusted.

Concerning the Trustee

The trustee, The Bank of New York Mellon, has provided banking and investment services to us in the past and may do so in the future as a part of its regular business.

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.

Anti-Takeover Considerations

The Delaware General Corporation Law, BlackRock’s restated certificate of incorporation and BlackRock’s amended and restated bylaws contain provisions which could serve to discourage or to make more difficult a change in control of BlackRock without the support of BlackRock’s board of directors or without meeting various other conditions.

Extraordinary Corporate Transactions

Delaware law provides that the holders of a majority of the shares entitled to vote must approve any fundamental corporate transactions such as mergers, sales of all or substantially all of a corporation’s assets, dissolutions, etc.

State Takeover Legislation

Section 203 of the Delaware General Corporation Law, in general, prohibits a business combination between a corporation and an interested stockholder within three years of the time such stockholder became an interested stockholder, unless (a) prior to such time, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder, (b) upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, exclusive of shares owned by directors who are also officers and by certain employee stock plans or (c) at or subsequent to such time, the business combination is approved by the board of directors and authorized by the affirmative vote at a stockholders’ meeting, and not by written consent, of at least 66 2/3% of the outstanding voting stock which is not owned by the interested stockholder. The restrictions of Section 203 of the Delaware General Corporation Law do not apply to certain business combinations or to corporations that have elected, in the manner provided therein, not to be subject to Section 203 of the Delaware General Corporation Law or, with certain exceptions, which do not have a class of voting stock that is listed on a national securities exchange or held of record by more than 2,000 stockholders. We have elected to be governed by Section 203 of the Delaware General Corporation Law.

Rights of Dissenting Stockholders

Delaware law does not afford appraisal rights in a merger transaction to holders of shares that are either listed on a national securities exchange or held of record by more than 2,000 stockholders, provided that such shares are

17

converted into stock of the surviving corporation or another corporation, which corporation in either case must also be listed on a national securities exchange or held of record by more than 2,000 stockholders. In addition, Delaware law denies appraisal rights to stockholders of the surviving corporation in a merger if the surviving corporation’s stockholders were not required to approve the merger.

Stockholder Action

Delaware law provides that, unless otherwise stated in BlackRock’s restated certificate of incorporation, any action which may be taken at an annual meeting or special meeting of stockholders may be taken without a meeting, if a consent in writing is signed by the holders of the outstanding stock having the minimum number of votes necessary to authorize the action at a meeting of stockholders. BlackRock’s restated certificate of incorporation provides that stockholders may take action by written consent if such action has been approved in advance by the majority vote of BlackRock’s board of directors.

Meetings of Stockholders

BlackRock’s restated certificate of incorporation provides that special meetings of the stockholders may be called at any time by the chairman of the board of directors, the president, a majority of the board of directors, any committee of the board of directors that has the power to call such meetings, or the chairman of the board of directors, the president or the corporate secretary upon a written request of one or more record holders of shares of BlackRock’s stock representing ownership of not less than 15 percent of the voting power of all outstanding shares of BlackRock’s stock, which request complies with the procedures for calling a special meeting of stockholders as set forth in BlackRock’s amended and restated bylaws, as they may be further amended from time to time.

Cumulative Voting

Delaware law permits stockholders to cumulate their votes and either cast them for one candidate or distribute them among two or more candidates in the election of directors only if expressly authorized in a corporation’s certificate of incorporation. BlackRock’s restated certificate of incorporation does not authorize cumulative voting.

Removal of Directors

Delaware law provides that, except in the case of a classified board of directors or where cumulative voting applies, a director, or the entire board of directors, of a corporation may be removed, with or without cause, by the affirmative vote of a majority of the shares of the corporation entitled to vote at an election of directors.

BlackRock’s restated certificate of incorporation provides that any or all of the directors may be removed, with or without cause, by the holders of a majority of the votes of capital stock then entitled to vote in the election of directors at a meeting of stockholders called for that purpose.

Vacancies

Delaware law provides that vacancies and newly created directorships resulting from a resignation or any increase in the authorized number of directors elected by all of the stockholders having the right to vote as a single class may be filled by a majority of the directors then in office, unless the governing documents of a corporation provide otherwise.

BlackRock’s amended and restated bylaws provide that newly created directorships resulting from an increase in the number of directors and vacancies occurring in the board of directors for any reason, may be filled by vote of a majority of the directors then in office, although less than a quorum, or by a sole remaining director or by the stockholders if the vacancy resulted from the action of stockholders.

18

No Preemptive Rights

Holders of common stock do not have any preemptive rights to subscribe for any additional shares of capital stock or other obligations convertible into or exercisable for shares of capital stock that we may issue in the future.

Board Term

BlackRock’s directors are elected annually for terms of one year.
