PROSPECTUS SUPPLEMENT

(To Prospectus dated March 21, 2025)

Up to 12,035,866 Shares of Common Stock Issuable Upon the Redemption of SubCo Units

This prospectus supplement is a supplement to the accompanying prospectus, dated March 21, 2025, and relates to the issuance by us of up to 12,035,866 shares (the “Shares”) of our common stock, $0.01 par value per share (the “common stock”), to the holders of Class B-2 membership units (“SubCo Units”) of BlackRock Saturn Subco, LLC (“Subco”), a consolidated subsidiary of BlackRock (as defined herein), from time to time upon redemption of an equal number of such SubCo Units pursuant to the terms of the Amended and Restated Operating Agreement of Subco (the “LLC Agreement”). The Shares consist of (i) up to 7,606,927 shares of common stock issuable upon redemption of 7,606,927 SubCo Units (the “Closing Consideration Units”) that were issued as closing date consideration for BlackRock’s acquisition of 100% of the business and assets of HPS Investment Partners (the “HPS Transaction”) at the closing of the HPS Transaction on July 1, 2025 (the “Closing”) and (ii) up to 4,428,939 shares of common stock issuable upon redemption of up to an additional 4,428,939 SubCo Units (the “Deferred Consideration Units”) that may be issued in the future as deferred consideration for the HPS Transaction, subject to the achievement of certain post-Closing conditions and financial performance milestones. Pursuant to the LLC Agreement, the SubCo Units will be redeemable, at the option of the Subco members holding such SubCo Units, at certain times following the one-year anniversary of the Closing (or, in the case of the Deferred Consideration Units, upon issuance) for either (i) one share of common stock (subject to certain proportionate adjustments) or (ii) a cash settlement amount (solely at the option of Subco). Under the LLC Agreement, BlackRock may elect to assume and perform SubCo’s redemption obligations by effecting the exchange of SubCo Units for common stock (or the cash settlement amount) through a direct exchange of such common stock (or cash settlement amount) with a redeeming member of Subco in exchange for such member’s SubCo Units on a one-for-one basis (subject to certain proportionate adjustments) (a “Direct Exchange”). We expect to elect to assume and perform Subco’s redemption obligations by way of Direct Exchanges for common stock pursuant to which the Shares registered pursuant to this prospectus supplement may be issued from time to time.

We will not receive any cash proceeds from the issuance of the Shares if we assume and perform Subco’s redemption obligations by way of a Direct Exchange.

Our common stock is listed for trading on the New York Stock Exchange (“NYSE”) under the symbol “BLK.” The last reported sale price of our common stock on June 29, 2026 was $950.17 per share.

Investing in our common stock involves risks, including those described in the “Risk Factors” section beginning on page S-6 of this prospectus supplement and the section entitled “Risk Factors” beginning on page 20 of BlackRock’s Annual Report on Form 10-K for the year ended December 31, 2025, which is incorporated by reference into this prospectus supplement.

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.

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 HPS Transaction and the acquisitions of Global Infrastructure Management, LLC (the “GIP Transaction”) and Preqin Holding Limited (“Preqin” or the “Preqin Transaction,” 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) the unfavorable resolution of legal proceedings; (9) the extent and timing of any share repurchases; (10) the impact, extent and timing of technological changes and the adequacy of intellectual property, data, information and cybersecurity protection; (11) the failure to effectively manage the development and use of artificial intelligence; (12) attempts to circumvent BlackRock’s operational control environment or the potential for human error in connection with BlackRock’s operational systems; (13) the impact of legislative and regulatory actions and reforms, supervisory or enforcement actions of government agencies and governmental scrutiny relating to BlackRock; (14) changes in law and policy and uncertainty pending any such changes; (15) any failure to effectively manage conflicts of interest; (16) damage to BlackRock’s reputation; (17) increasing focus from stakeholders regarding environmental and social-related matters; (18) geopolitical unrest, terrorist activities, civil or international hostilities, and other events outside BlackRock’s control, including wars, global trade tensions, tariffs, natural disasters and health crises, which may adversely affect the general economy, domestic and local financial and capital markets, specific industries or BlackRock; (19) climate-related risks to BlackRock’s business, products, operations and clients; (20) the ability to attract, train and retain highly qualified professionals; (21) fluctuations in the carrying value of BlackRock’s economic investments; (22) 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; (23) BlackRock’s success in negotiating distribution arrangements and maintaining distribution channels for its products; (24) the failure by key third-party providers to fulfill their obligations to BlackRock; (25) operational, technological and regulatory risks associated with BlackRock’s major technology partnerships; (26) any disruption to the operations of third parties whose functions are integral to BlackRock’s exchange-traded products platform; (27) the impact of BlackRock electing to provide support to its products from time to

S-2

time and any potential liabilities related to securities lending or other indemnification obligations; and (28) 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 our common stock 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 our common stock. 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, 2025 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, 2025, 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 our Common Stock

Future sales of our common stock in the public market or the issuance of other equity or equity-linked securities could adversely affect the trading price of our common stock.

Sale of a substantial number of shares of our common stock in the public markets, or the perception that these sales might occur, could cause the market price of our common stock to decline or could impair our ability to raise capital through a future sale of, or pay for acquisitions using, our equity or equity-linked securities.

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

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

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

S-6

Additional issuances of equity or equity-linked securities would dilute the ownership of existing stockholders and could reduce our earnings per share.

We may issue equity or equity-linked securities in the future in connection with capital raisings, acquisitions, strategic transactions or for other purposes. To the extent we issue additional equity or equity-linked securities, the ownership of our existing stockholders would be diluted and our earnings per share could be reduced.

S-7

USE OF PROCEEDS

BlackRock expects to assume and perform all redemption obligations of Subco with respect to SubCo Units by way of Direct Exchanges. We will not receive any cash proceeds from the issuance of any Shares as described herein.

S-8

U.S. FEDERAL INCOME TAX CONSIDERATIONS TO NON-U.S. HOLDERS

The following is a discussion of certain material U.S. federal income tax consequences of the purchase, ownership and disposition of SubCo Units and our common stock by a non-U.S. holder (as defined herein) as of the date hereof. This summary deals only with SubCo Units and our common stock that are held as a capital asset by a non-U.S. holder.

A “non-U.S. holder” means a person (other than a partnership or any other entity treated as a partnership for United States federal income tax purposes) that is not for United States federal income tax purposes any of the following:

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income tax consequences different from those summarized below. This summary does not address all aspects of United States federal income taxes, nor does it address any other U.S. federal tax consequences (e.g., estate or gift tax or the Medicare tax on net investment income) or any foreign, state, local or other tax considerations that may be relevant to non-U.S. holders in light of their personal circumstances. In addition, this summary does not represent a detailed description of the United States federal income tax consequences applicable to holders that are subject to special treatment under the United States federal income tax laws (including a holder that is a United States expatriate, a “controlled foreign corporation,” a “passive foreign investment company,” or a partnership or other pass-through entity for United States federal income tax purposes). We cannot provide assurance that a change in law will not alter significantly the tax considerations that are described in this summary.

If a partnership holds SubCo Units or our common stock, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. Non-U.S. holders that are partners of a partnership holding SubCo Units or our common stock should consult their tax advisors.

Non-U.S. holders considering exchanging SubCo Units for our common stock should consult their own tax advisors concerning the particular United States federal income tax consequences of the exchange and ownership of our common stock, as well as the consequences arising under the laws of any other taxing jurisdiction.

Tax Treatment of the Sale of SubCo Units

Given that we will elect to assume and perform the redemption obligation by way of a Direct Exchange, the exchange will be treated by us as a sale of such units by the redeeming holder to us in a fully taxable transaction, wherein the redeeming holder will be treated as realizing for tax purposes an amount equal to the sum of the cash or the value of our common stock received in the exchange.

S-9

Any gain realized on the disposition of SubCo Units by a non-U.S. holder generally will not be subject to United States federal income tax unless:

A non-U.S. holder described in the first bullet point immediately above will be subject to tax on the net gain derived from the sale in the same manner as if it were a United States person as defined under the Code. A non-U.S. holder described in the first bullet point immediately above that is a foreign corporation and may also be subject to a branch profits tax equal to 30% of its effectively connected earnings and profits (with certain adjustments) or at such lower rate as may be specified by an applicable income tax treaty. An individual non-U.S. holder described in the second bullet point immediately above will be subject to a flat 30% tax on the gain derived from the sale, which may be offset by United States-source capital losses, even though the individual is not considered a resident of the United States.

We believe Subco has not been and is not currently a “United States real property holding corporation” for United States federal income tax purposes; however, no assurance can be given that Subco will not become one in the future. Non-U.S. holders should consult their own tax advisors about the consequences that could result if Subco is, or becomes, a “United States real property holding corporation.”

Tax Treatment to Non-U.S. Holders of Owning and Disposing of Our Common Stock

Dividends

Distributions paid on our common stock will be taxable as dividends to the extent paid out of current or accumulated earnings and profits, as determined under United States federal income tax principles. Dividends paid to a non-U.S. holder of our common stock generally will be subject to withholding of United States federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. However, dividends that are effectively connected with the conduct of a trade or business by the non-U.S. holder within the United States (and, if required by an applicable income tax treaty, are attributable to a United States permanent establishment of the non-U.S. holder) are not subject to withholding tax, provided certain certification and disclosure requirements are satisfied. Instead, such dividends are subject to United States federal income tax on a net income basis in the same manner as if the non-U.S. holder were a United States person as defined under the Code. In addition, any such effectively connected dividends received by a foreign corporation may be subject to a branch profits tax equal to 30% of its effectively connected earnings and profits (with certain adjustments) or such lower rate as may be specified by an applicable income tax treaty.

A non-U.S. holder of our common stock who wishes to claim the benefit of an applicable treaty rate for dividends will generally be required (i) to complete Internal Revenue Service (“IRS”) Form W-8BEN or W-8BEN-E and certify under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (ii) if our common stock is held through certain foreign intermediaries, to satisfy certain relevant certification requirements set forth under applicable Treasury Regulations. Special certification and other requirements apply to certain non-U.S. holders that are pass-through entities rather than corporations or individuals.

S-10

A non-U.S. holder of our common stock eligible for a reduced rate of United States withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS.

Gain on Disposition of Common Stock

Any gain realized on the disposition of our common stock by a non-U.S. holder generally will not be subject to United States federal income tax unless:

A non-U.S. holder described in the first bullet point immediately above will be subject to tax on the net gain derived from the sale in the same manner as if it were a United States person as defined under the Code. A non-U.S. holder described in the first bullet point immediately above that is a foreign corporation and may also be subject to a branch profits tax equal to 30% of its effectively connected earnings and profits (with certain adjustments) or at such lower rate as may be specified by an applicable income tax treaty. An individual non-U.S. holder described in the second bullet point immediately above will be subject to a flat 30% tax on the gain derived from the sale, which may be offset by United States-source capital losses, even though the individual is not considered a resident of the United States.

We believe we have not been and are not currently a “United States real property holding corporation” for United States federal income tax purposes; however, no assurance can be given that we will not become one in the future. Non-U.S. holders should consult their own tax advisors about the consequences that could result if we are, or become, a “United States real property holding corporation.”

Information Reporting and Backup Withholding

We must report annually to the IRS and to each non-U.S. holder the amount of dividends paid to such holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty.

A non-U.S. holder will be subject to backup withholding for dividends paid to such holder unless such holder certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that such holder is a United States person as defined under the Code), or such holder otherwise establishes an exemption.

Information reporting and, depending on the circumstances, backup withholding will apply to the proceeds of a sale of our common stock within the United States or conducted through certain United States-related financial intermediaries, unless the beneficial owner certifies under penalty of perjury that it is a non-U.S. holder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person as defined under the Code), or such owner otherwise establishes an exemption.

S-11

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a non-U.S. holder’s United States federal income tax liability provided the required information is furnished to the IRS.

Foreign Account Tax Compliance Act

Withholding at a rate of 30% will generally be required in certain circumstances on dividends in respect of shares of our common stock held by or through certain foreign 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, or 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 our common stock is held will affect the determination of whether such withholding is required. Similarly, dividends in respect of our common stock held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exceptions 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 the payer will in turn be required to provide to the U.S. Department of the Treasury. Prospective investors are urged to consult their tax advisers regarding the possible implications of these rules on their investment in our common stock.

S-12

PLAN OF DISTRIBUTION

This prospectus supplement relates to the issuance by us of up to 12,035,866 Shares if, and to the extent that, holders of SubCo Units exercise their right to have their SubCo Units redeemed. Pursuant to the LLC Agreement, the SubCo Units will be redeemable, at the option of the Subco members holding such SubCo Units, at certain times following the one-year anniversary of the Closing (or, in the case of the Deferred Consideration Units, upon issuance) for either (i) one share of common stock (subject to certain proportionate adjustments) or (ii) a cash settlement amount (solely at the option of Subco). Under the LLC Agreement, BlackRock may elect to assume and perform SubCo’s redemption obligations by effecting a Direct Exchange. We expect to elect to assume and perform Subco’s redemption obligations by way of Direct Exchanges for common stock pursuant to which the Shares registered pursuant to this prospectus supplement may be issued from time to time. The registration of the issuance of such shares of our common stock will permit the holders of SubCo Units to sell such shares of our common stock received in a Direct Exchange without restriction in the open market (or otherwise), subject to certain contractual lock-up restrictions; however, such registration does not necessarily mean that any of the holders of SubCo Units will exercise their right to have their SubCo Units redeemed. We will not receive any cash proceeds from the issuance of Shares if we elect to effect Direct Exchanges of such SubCo Units for our common stock.

We have agreed to pay certain expenses for the registration of the Shares, including:

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.
