ABOUT THIS PROSPECTUS SUPPLEMENT

When used in this prospectus supplement, the terms “BlackRock,” “Company,” “we,” “our” and “us” refer to BlackRock, Inc. and its subsidiaries, unless otherwise specified.

This document is in two parts. The first part is this prospectus supplement, which contains specific information about us and the terms on which we are offering and issuing notes. The second part is the accompanying prospectus dated April 9, 2021, which contains and incorporates by reference important business and financial information about us and other information about the offering.

This prospectus supplement and the accompanying prospectus are part of a registration statement that we filed with the SEC using a “shelf” registration process. Under this shelf process, we may, from time to time, sell notes in one or more offerings. This prospectus supplement also adds to, updates and changes information contained in the accompanying prospectus. You should read both this prospectus supplement and the accompanying prospectus as well as additional information described under “Where You Can Find More Information and Incorporation By Reference” beginning on page S-30 of this prospectus supplement before investing in our notes. Generally, when we refer to the prospectus, we are referring to both parts of this document combined together with additional information described under “Where You Can Find More Information and Incorporation By Reference” on page S-30.

Before you invest in our notes, you also should carefully read the registration statement (including the exhibits thereto) of which this prospectus supplement and the accompanying prospectus form a part, this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein.

We are responsible for the information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus or in any free writing prospectus. Neither we nor any of the underwriters have authorized anyone to provide you with different information. We are not, and the underwriters are not, making an offer to sell our notes in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein or therein is accurate only as of their respective dates. Our business, financial condition, results of operations and prospects may have changed since those dates.

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) a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended or superseded, “MiFID II”); (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”) and (b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes. 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) a retail investor in the United Kingdom means a person who is one (or more) of: (i) a retail client as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (“EUWA”); (ii) a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (as amended, the “FSMA”) and any rules or regulations made under the FSMA to implement the Insurance Distribution Directive, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; (iii) not a qualified investor as defined in Article 2 of the Prospectus Regulation as it forms part of domestic law by virtue of the EUWA (the “UK Prospectus Regulation”), and (b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes. Consequently, no key information document required by the PRIIPs Regulation as it forms part of UK domestic law by virtue of the EUWA (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 PRIPPs 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. This prospectus supplement and the accompanying prospectus are not a prospectus for the purposes of the UK Prospectus Regulation.

The Offering

Issuer BlackRock, Inc.

Securities Offered $1,000,000,000 aggregate principal amount of 2.10% Notes due 2032.

Maturity Date February 25, 2032.

Interest Rate 2.10% per year.

Interest Payment Dates February 25 and August 25 of each year, beginning February 25, 2022.

Redemption of the Notes Prior to November 25, 2031 (the date that is three (3) months prior to maturity), we may, at our option, redeem some or all of the notes at any time and from time to time a at a “make-whole” redemption price plus accrued and unpaid interest thereon to, but excluding, the redemption date.

On or after November 25, 2031 (the date that is three (3) months prior to maturity) we may, at our option, redeem some or all of the notes at any time and from time to time at a redemption price equal to 100% of the principal amount of the notes, plus accrued and unpaid interest thereon to, but excluding, the redemption date. For more detailed information on the calculation of the redemption price, see “Description of the Notes—Optional Redemption of the Notes.”

Priority The notes will be our unsecured and unsubordinated obligations and will rank equal in right of payment with each other and with all our existing and future unsubordinated indebtedness. We are a holding company and, accordingly, substantially all of our operations are conducted through our subsidiaries. As a result, our debt is “structurally subordinated” to all existing and future debt, trade creditors and other liabilities of our subsidiaries. Thus, our rights as a creditor would be effectively junior to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to that held by us. Our rights, and the rights of our creditors, to participate in any distribution of assets of any subsidiary upon its liquidation or reorganization or otherwise would be subject to the prior claims of that subsidiary’s creditors, except to the extent that our claims as a creditor of such subsidiary may be recognized. As of September 30, 2021, we had outstanding an aggregate principal amount of $6.51 billion of unsecured long-term indebtedness and no short-term indebtedness.

Covenants The indenture includes requirements that must be met if we consolidate or merge with, or sell all or substantially all of our assets to, another entity.

Trustee The Bank of New York Mellon under the Senior Indenture dated as of September 17, 2007.

S-7

Additional Notes From time to time, without the consent of the holders of the notes, we may 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 will constitute a single series of debt securities under the indenture with the previously issued notes; provided that if the additional debt securities are not fungible with the notes for U.S. federal income tax purposes, such additional debt securities will be issued with a separate CUSIP number.

Use of Proceeds The net proceeds from this offering will be $986,600,000 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 the repayment of all or a portion of our outstanding 3.375% Notes due 2022. See “Use of Proceeds” in this prospectus supplement.

Denominations and Form The notes will be book-entry only and registered in the name of a nominee of DTC. Investors may elect to hold interests in the notes through Clearstream or Euroclear, as operator of the Euroclear System, if they are participants in these systems, or indirectly through organizations that are participants in these systems. The notes will be issued only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Risk Factors Investing in the notes involves substantial risks. See “Risk Factors” beginning on page S-9 of this prospectus supplement, the section entitled “Risk Factors” beginning on page 19 of our Annual Report on Form 10-K for the year ended December 31, 2020 and the section entitled “Risk Factors” on page 78 of our Quarterly Report on Form 10-Q for the quarter ended September 30, 2021, each of which is incorporated by reference herein, for a description of certain risks that you should consider before investing in the notes.

S-8

RISK FACTORS

Any investment in our 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 our notes. In addition, you should carefully consider, among other things, the matters discussed under “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020 and in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2021, and other documents that we subsequently file with the SEC, all of which are incorporated by reference into this prospectus supplement. The risks and uncertainties described below, in our Annual Report on Form 10-K for the year ended December 31, 2020 and in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2021, 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 September 30, 2021, we had outstanding an aggregate principal amount of $6.51 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 are obligations exclusively of BlackRock, Inc. and not of our subsidiaries and payment to holders of the notes will be structurally subordinated to the claims of our subsidiaries’ creditors.

The notes are not guaranteed by any of our subsidiaries. As a result, liabilities, including indebtedness or guarantees of indebtedness, of each of our subsidiaries will rank effectively senior to the indebtedness represented by the notes, to the extent of such subsidiary’s assets. In addition, the indenture governing the notes does not restrict the future incurrence of liabilities or issuances of preferred stock, including unsecured indebtedness or guarantees of indebtedness, by our subsidiaries.

The notes will be effectively junior to secured indebtedness that we may issue in the future.

The notes are unsecured. Holders of any secured debt that we 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. Holders of our secured debt also would have priority over unsecured creditors in the event of our bankruptcy, liquidation or similar proceeding. As a result, the notes will be effectively junior to any secured debt that we may issue in the future.

There is no public market for the notes, which could limit their market price or your ability to sell them.

We can give no assurances concerning the liquidity of any market that may develop for the notes offered hereby, the ability of 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.

DESCRIPTION OF THE NOTES

Set forth below is a description of the specific terms of the notes. This description supplements, and should be read together with, the description of the general terms and provisions of the debt securities set forth in the accompanying prospectus under the caption “Description of Debt Securities.” In addition to reading the description of the notes in this prospectus supplement and in the accompanying prospectus, you should also read the senior indenture referred to in the accompanying prospectus under which the notes are to be issued (the “indenture”). 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. When used in this section, the terms “BlackRock,” “we,” “our” and “us” refer solely to BlackRock, Inc. and not to its subsidiaries.

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 $2,000 and integral multiples of $1,000 in excess thereof. The notes will mature on February 25, 2032.

The notes will be issued as a separate series of senior debt securities under the indenture. The indenture does not limit the amount of other debt that we may incur. We 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. We 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 for U.S. federal income tax purposes, such additional debt securities will be issued with a separate CUSIP number.

The notes will bear interest from December 10, 2021, at the annual rate of 2.10%. Interest on the notes will be payable semi-annually on February 25 and August 25 of each year, commencing February 25, 2022, to the persons in whose names the notes are registered at the close of business on the immediately preceding February 15 and August 15, respectively (whether or not a business day), subject to certain exceptions.

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

The notes do not provide for any sinking fund.

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

Optional Redemption of the Notes

Prior to November 25, 2031 (the date that is three (3) months prior to maturity (the “Par Call Date”)), we may, at our option, redeem some or all of the notes at any time and from time to time at a redemption price equal to the greater of (i) 100% of the principal amount of the notes being redeemed and (ii) the Make-Whole Redemption Amount, plus, in each case, accrued and unpaid interest thereon to, but excluding, the redemption date. Definitions related to this paragraph are found below, at the end of this subsection (“Optional Redemption of the Notes”).

On or after the Par Call Date, we may, at our option, redeem some or all of the notes 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.

S-14

“Make-Whole Redemption Amount” means, with respect to any redemption date, the sum of the present values of the remaining scheduled payments of principal and interest on the notes being redeemed (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, assuming that the notes being redeemed matured on, and that accrued and unpaid interest on such notes was payable through, the Par Call Date.

“Treasury Rate” means, the arithmetic mean (rounded to the nearest one-hundredth of one percent) of the yields displayed for each of the five most recent days published in the most recent Statistical Release under the caption “Treasury constant maturities” for the maturity (rounded to the nearest month) corresponding to the remaining life to maturity of the notes (assuming the notes mature on the Par Call Date) as of the date of redemption. If no maturity exactly corresponds to such remaining life to maturity, yields for the two published maturities most closely corresponding to such remaining life to maturity shall be calculated pursuant to the immediately preceding sentence and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month. The Treasury Rate will be calculated by us on the third business day preceding the date the applicable notice of redemption is given. For the purpose of calculating the Treasury Rate, the most recent Statistical Release published prior to the date of calculation of the Treasury Rate shall be used.

“Statistical Release” means that statistical release designated “H. 15” or any successor publication published daily by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity, or, if such release (or any successor publication) is no longer published at the time of any calculation under the Indenture, then such other reasonably comparable index the Company designates.

Notice of any redemption will be sent 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 notes will be selected for redemption as follows:

• if the notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the notes are listed; or

• if the notes are not listed on any national securities exchange, in accordance with the applicable procedures of the depositary or, in the case of definitive notes, by lot or otherwise by such method as the trustee shall deem fair and appropriate; provided that partial redemptions must be in an amount not less than $1,000 principal amount of notes if the trustee selects for redemption portions of the principal amount of notes with a denomination larger than the minimum authorized denomination for the notes or of the principal amount of the global notes, if such selection is in accordance with the applicable procedures of the depositary.

Any redemption notice may, at our 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 our 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, 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 Company in its sole discretion) by the date of redemption, or by the date of redemption as so delayed.

Unless we default 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 are our obligations exclusively, and are not obligations of our subsidiaries. We are a holding company and, accordingly, substantially all of our operations are conducted through our subsidiaries. As a result,

S-15

our cash flow and our ability to service our debt, including the notes, depend upon the earnings of our subsidiaries. In addition, we depend on the distribution of earnings, loans or other payments by our subsidiaries to us.

Our subsidiaries are separate and distinct legal entities. Our subsidiaries have no obligation to pay any amounts due on the notes or to provide us with funds for our payment obligations. In addition, any payment of dividends, distributions, loans or advances by our subsidiaries to us could be subject to statutory or contractual restrictions. Payments due to us by our subsidiaries will also be contingent upon our subsidiaries’ earnings and business considerations.

Our right to receive any assets of any of our 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 we were a creditor of any of our subsidiaries, our rights as a creditor would be effectively junior to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to that held by us.

Book-Entry System; Delivery and Form

The notes will be issued in the form of one or more fully registered global securities which will be deposited with, or on behalf of, DTC, New York, New York, and registered in the name of Cede & Co., DTC’s nominee. We will not issue notes in certificated form. Beneficial interests in the global securities will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the global securities through either DTC in the United States, or Clearstream Banking, société anonyme, or Euroclear Bank S.A./N.V., as operator of the Euroclear System in Europe, referred to as Clearstream and Euroclear, if they are participants of those systems, or, indirectly, through organizations that are participants in those systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositories, which in turn will hold such interests in customers’ securities accounts in the depositories’ names on the books of DTC. Beneficial interests in the global securities will be held in denominations of $2,000 and integral multiples of $1,000 in excess thereof. Except as set forth below, the global securities may be transferred, in whole but not in part, only to another nominee of DTC or to a successor to DTC or its nominee.

DTC is a limited-purpose trust company organized under the New York Banking Law, a banking organization within the meaning of the New York Banking Law, a member of the Federal Reserve System, a clearing corporation within the meaning of the New York Uniform Commercial Code, and a clearing agency registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). DTC holds and provides asset servicing for issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments that DTC’s participants, which we refer to as direct participants, deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between direct participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. Access to the DTC system also is available to others, such as U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. We refer to those entities as indirect participants.

Purchases of notes under the DTC system must be made by or through direct participants, who receive a credit for the notes on DTC’s records. The ownership interest of each actual purchaser of each note, who we refer

S-16

to as a beneficial owner, is in turn recorded on the direct and indirect participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participants through whom the beneficial owner entered into the transaction. Transfers of ownership interests in the notes will be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the notes, except in the event that use of the book-entry system for the notes is discontinued.

To facilitate subsequent transfers, all notes deposited by direct participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of notes with DTC and their registration in the name of Cede & Co. or another DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the notes. DTC’s records reflect only the identity of the direct participants to whose accounts the notes are credited, which may or may not be the beneficial owners. The direct and indirect participants remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct 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.

Redemption notices will be sent to DTC. If less than all of the notes are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in the notes to be redeemed.

Neither DTC, Cede & Co. nor any other DTC nominee will consent or vote with respect to the notes unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts notes are credited on the record date.

Redemption proceeds, distributions and interest payments on the notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us on the payable date in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in street name, and will be the responsibility of such participant and not of DTC or its nominee, us or the trustee, subject to any statutory or regulatory requirements in effect from time to time. Payment of redemption proceeds, distributions, and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is the responsibility of us. Disbursement of such payments to direct participants will be the responsibility of DTC, and disbursement of such payments to the beneficial owners will be the responsibility of direct and indirect participants.

DTC may discontinue providing its services as depository with respect to the notes at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depository is not obtained, certificates representing the affected notes are required to be printed and delivered. In addition, we may decide to discontinue use of the system of book-entry transfers through DTC or a successor securities depository with respect to the notes (subject to DTC’s or such successor securities depository’s procedures). In that event, certificates representing the notes will be printed and delivered. In the event that individual certificates are issued, holders of the notes will be able to receive payments, including principal and interest on the notes, and effect transfer of the notes at the offices of our paying and transfer agent.

S-17

Similar to DTC, Euroclear and Clearstream hold securities for participating organizations. They also facilitate the clearance and settlement of securities transactions between their respective participants through electronic book-entry changes in the accounts of such participants. Euroclear and Clearstream provide various services to their participants, including the safekeeping, administration, clearance, settlement, lending and borrowing of internationally traded securities. Euroclear and Clearstream interface with domestic securities markets. Euroclear and Clearstream participants are financial institutions such as underwriters, securities brokers and dealers, banks, trust companies and certain other organizations. Indirect access to Euroclear and Clearstream is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Euroclear and Clearstream participant, either directly or indirectly.

Distributions with respect to notes held beneficially through Euroclear or Clearstream will be credited to the cash accounts of participants in Euroclear or Clearstream, as the case may be, in accordance with their respective procedures, to the extent received by the common depositary for Euroclear or Clearstream.

The information in this section concerning DTC, Euroclear and Clearstream have been obtained from sources that we believe to be reliable, but neither we nor the trustee take any responsibility for the accuracy of the information.

Global Clearance and Settlement Procedures

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between participants will occur in the ordinary way in accordance with DTC’s rules and will be settled in immediately available funds using DTC’s Same-Day Funds Settlement System. Secondary market trading between Clearstream participants and Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC on the one hand, and directly or indirectly through Clearstream or Euroclear participants, on the other, will be effected within DTC in accordance with DTC’s rules on behalf of the relevant European international clearing system by its U.S. depository; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the participant in such system in accordance with its rules and procedures and within its established deadlines. The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depository to take action to effect final settlement on its behalf by delivering or receiving notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream participants and Euroclear participants may not deliver instructions directly to their respective U.S. depositories. Because of time-zone differences, credits of notes received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits, or any transactions in the notes settled during such processing, will be reported to the relevant Euroclear participants or Clearstream participants on that business day. Cash received in Clearstream or Euroclear as a result of sales of notes by or through a Clearstream participant or a Euroclear participant to a DTC participant will be received with value on the business day of settlement in DTC but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following DTC settlement in DTC.

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

S-18

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

The following discussion is a summary of U.S. federal income tax considerations generally applicable to the ownership and disposition of the notes by Non-U.S. Holders (as defined below) that purchase the notes for cash pursuant to this offering at the initial sale price. This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), U.S. 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 all of the tax considerations that may be relevant to Non-U.S. Holders subject to special tax treatment, such as insurance companies, 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,” persons who participate in a contemporaneous redemption of our outstanding indebtedness, 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).

Non-U.S. Holders should consult their tax advisors as to the particular tax consequences to them of purchasing, owning, and disposing of the notes, including the application and effect of U.S. federal, state, local and foreign tax laws.

For purposes of this summary, a Non-U.S. Holder is a beneficial owner of the notes that is not, for U.S. federal income tax purposes, (1) an individual who is a citizen or resident of the United States, (2) a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) an estate, the income of which is subject to U.S. federal income taxation regardless of its source, or (4) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or (b) the trust has in effect a valid election to be treated as a domestic trust 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.

Payments of Interest on the Notes

Subject to the discussions below concerning backup withholding and 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:

• the Non-U.S. Holder does not actually or constructively own 10% or more of our voting stock;

• the Non-U.S. Holder is not a controlled foreign corporation that is related to us (actually or constructively) through stock ownership; and

• the Non-U.S. Holder provides its name, address, and certain other information on an IRS Form W-8BEN or W-8BEN-E (or other applicable form), and certifies, under penalties of perjury, that it is not a United States person and neither we nor the paying agent (or other withholding agent) have actual knowledge or reason to know that the beneficial owner of the note is a United States person.

S-19

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 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.

Sale, Exchange, Retirement, or Other Disposition of the Notes

Subject to the discussions below concerning backup withholding, a Non-U.S. Holder will generally not be subject to U.S. federal income or withholding tax on the receipt of payments of principal on a note, or on any gain realized on the sale, exchange, retirement, or other taxable disposition (each, 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 on the Notes”), unless:

• such gain or income is effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States (and, if required under an applicable income tax treaty, is attributable to the Non-U.S. Holder’s permanent establishment or fixed base in the United States); or

• the Non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met.

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.

Information Reporting and Backup Withholding

Payments of interest made by us or our paying agent on, and the proceeds from the sale or other disposition of, the notes will generally be subject to information reporting and U.S. federal backup withholding if a Non-U.S. Holder receiving such payment fails to comply with applicable United States information reporting or certification requirements. Such requirements are generally satisfied by providing a properly executed IRS Form W-8BEN or W-8BEN-E (or appropriate substitute form) as described above. Backup withholding is not an additional tax and any amount withheld under the backup withholding rules is generally allowable as a credit against the Non-U.S. Holder’s U.S. federal income tax liability; provided that the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act

Withholding at a rate of 30% will generally be required in certain circumstances on interest payable on notes held by or through certain financial institutions (including investment funds), unless such institution

S-20

(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 United States persons or by certain non-U.S. entities that are wholly or partially owned by United States persons and to withhold on certain payments, (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 United States authorities, or (iii) otherwise qualifies for an exemption. Accordingly, the entity through which the 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. An intergovernmental agreement between the United States and the applicable foreign country may modify these requirements. We will not pay additional amounts to Non-U.S. Holders in respect of any amounts withheld. Prospective investors should consult their tax advisors regarding the possible implications of these rules on an investment in the notes.

Mischler Financial Group, Inc.	$	24,363,000
Siebert Williams Shank & Co., LLC	$	8,000,000
Total	$	1,000,000,000

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 nondefaulting 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 of 1933, as amended (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.

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 price less a concession 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.

S-22

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

	Per Note			Total
Public Offering Price(1)		99.110	%	$	991,100,000
Underwriting Discount		0.450	%	$	4,500,000
Proceeds, before Expenses, to BlackRock		98.660	%	$	986,600,000

(1) Plus accrued interest, if any, from December 10, 2021.

The expenses of the offering, not including the underwriting discount, are estimated at $1.9 million and are payable by us.

Price Stabilization and Penalty Bids

In connection with the offering of the notes, the underwriters (or persons acting on behalf of any underwriter(s)) may purchase and sell the notes in the open market. These transactions may include overallotment, syndicate covering transactions and stabilizing transactions. Over-allotment 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 underwriter(s) (or persons acting on behalf of any underwriter) 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 relevant underwriter(s) (or person(s) acting on behalf of any underwriter(s)) 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 underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

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 our commercial paper program. In addition, certain of the underwriters and/or their affiliates are lenders under our $4.4 billion revolving credit facility maturing in 2026.

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

S-23

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.

In addition, certain underwriters and/or their affiliates may hold positions in the 3.375% Notes due 2022, which may be repaid with the net proceeds of this offering, and accordingly, such underwriters may receive a portion of the net proceeds of the offering in connection with such repayment.

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 two business days, unless the parties to a trade expressly agree otherwise. Accordingly, investors who wish to trade notes prior to two business days 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 two business days before their date of delivery hereunder should consult their advisors.

Selling Restrictions

ICBC Standard Bank Plc

ICBC Standard Bank Plc is restricted in its U.S. securities dealings under the United States Bank Holding Company Act and is not a U.S.-registered broker-dealer. All sales of securities in the U.S. will be made by or through U.S.-registered broker-dealers. ICBC Standard Bank Plc may not underwrite, subscribe, agree to purchase or procure purchasers to purchase notes that are offered or sold in the United States. Accordingly, ICBC Standard Bank Plc shall not be obligated to, and shall not, underwrite, subscribe, agree to purchase or procure purchasers to purchase notes that may be offered or sold by other underwriters in the United States. ICBC Standard Bank Plc shall offer and sell notes constituting part of its allotment solely outside the United States.

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.

S-24

European Economic Area

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

(a) 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 MiFID II; or

(ii) a customer within the meaning of the Insurance Distribution Directive, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or

(iii) not a qualified investor as defined in the Prospectus Regulation, and

(b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes.

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:

(a) a retail investor means a person who is one (or more) of the following:

(i) a retail client as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the EUWA; or

(ii) a customer within the meaning of the provisions of the FSMA and any rules or regulations made under the FSMA to implement the Insurance Distribution Directive, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or

(iii) not a qualified investor as defined in Article 2 of the Prospectus Regulation as it forms part of domestic law by virtue of the EUWA; and

(b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes.

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 PRIPPs 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

S-25

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 FSMA does not apply to BlackRock; and (b) it has complied and will comply with all applicable provisions of FSMA with respect to anything done by it in relation to the notes in, from or otherwise involving the United Kingdom.

Each of the risks described in these documents could materially and adversely affect our business, financial condition, results of operations and prospects, and could result in a partial or complete loss of your investment. See “Where You Can Find More Information” in this prospectus. You should also carefully review the cautionary statement in this prospectus referred to under “Special Note Regarding Forward-Looking Statements.”

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, 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. 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, including in any accompanying prospectus supplement, among others, could cause actual results to differ materially from forward-looking statements or historical performance and include: (1) a pandemic or health crisis, including the COVID-19 pandemic, and its continued impact on financial institutions, the global economy or capital markets, as well as BlackRock’s products, clients, vendors and employees, and BlackRock’s results of operations, the full extent of which may be unknown; (2) the introduction, withdrawal, success and timing of business initiatives and strategies; (3) 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 AUM; (4) the relative and absolute investment performance of BlackRock’s investment products; (5) BlackRock’s ability to develop new products and services that address client preferences; (6) the impact of increased competition; (7) the impact of future acquisitions or divestitures; (8) BlackRock’s ability to integrate acquired businesses successfully; (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, information and cyber security protection; (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 and regulatory, supervisory or enforcement actions of government agencies 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) terrorist activities, civil unrest, international hostilities and natural disasters, which may adversely affect the general economy, domestic and local financial and capital markets, specific industries or BlackRock; (18) the ability to attract and retain highly talented professionals; (19) fluctuations in the carrying value of BlackRock’s economic investments; (20) the impact of changes to tax legislation, including income, payroll and transaction taxes, and taxation on products or transactions, which could affect the value proposition to clients and, generally, the tax position of the Company; (21) BlackRock’s success in negotiating distribution arrangements and maintaining distribution channels for its products; (22) the failure by a key vendor of BlackRock to fulfill its obligations to the Company; (23) operational, technological and regulatory risks associated with BlackRock’s major technology partnerships; (24) any disruption to the operations of third parties whose functions are integral to BlackRock’s exchange-traded funds (“ETF”) platform; (25) 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 (26) the impact of problems at other financial institutions or the failure or negative performance of products at other financial institutions.

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

DESCRIPTION OF DEBT SECURITIES

This prospectus describes certain general terms and provisions of the debt securities. The debt securities will constitute either unsecured senior debt or unsecured subordinated debt. We will issue debt securities that will be senior debt under an indenture between us and The Bank of New York Mellon, as trustee (the “senior indenture”), dated September 17, 2007. We will issue debt securities that will be subordinated debt under an indenture between us and The Bank of New York Mellon, as trustee (“subordinated indenture”). This prospectus refers to the senior indenture and the subordinated indenture individually as the “indenture” and collectively as the “indentures.” The term “trustee” refers to the trustee under each indenture, as appropriate.

The indentures are subject to and governed by the Trust Indenture Act of 1939, as amended. The indentures are substantially identical, except for the provisions relating to subordination, which are included only in the subordinated indenture. The following summary of the material provisions of the indentures and the debt securities is not complete and is subject to, and is qualified in its entirety by reference to, all of the provisions of the indentures, each of which has been filed as an exhibit to the registration statement of which this prospectus is a part. We urge you to read the indenture that is applicable to you because it, and not the summary below, defines your rights as a holder of debt securities. You can obtain copies of the indentures by following the directions described under the heading “Where You Can Find More Information” on page 4.

General

The senior debt securities will rank equally with all of our other unsubordinated debt. The subordinated debt securities will be subordinated in right of payment to our “Senior Indebtedness.” For additional information, see “—Subordination” below. As of December 31, 2020, approximately $7.264 billion aggregate principal amount of debt securities was outstanding under the senior indenture and no other senior indebtedness was outstanding. As of December 31, 2020, none of BlackRock’s existing debt would have been subordinated to the senior debt securities and none of such debt would have ranked equally with any subordinated debt securities offered pursuant to this registration statement. The indentures do not limit the amount of debt, either secured or unsecured, which may be issued by us under the indentures or otherwise. The debt securities may be issued in one or more series with the same or various maturities and may be sold at par, a premium or an original issue discount. Debt securities sold at an original issue discount may bear no interest or interest at a rate which is below market rates. Since BlackRock is a holding company, the right of BlackRock, and hence the rights of the creditors and securityholders of BlackRock, to participate in any distribution of assets of any subsidiary upon its liquidation or reorganization or otherwise is accordingly subject to prior claims of creditors of the subsidiary, except to the extent that claims of BlackRock itself as a creditor of the subsidiary may be recognized. The indentures do not prohibit us or our subsidiaries from incurring debt or agreeing to limitations on their ability to pay dividends or make other distributions to us.

Each prospectus supplement will describe the terms relating to the specific series of debt securities being offered. These terms will include some or all of the following:

• the title of debt securities and whether they are subordinated debt securities or senior debt securities;

• any limit on the aggregate principal amount of the debt securities;

• the ability to issue additional debt securities of the same series;

• the price or prices at which we will sell the debt securities;

• the maturity date or dates of the debt securities;

• the rate or rates of interest, if any, which may be fixed or variable, at which the debt securities will bear interest, or the method of determining such rate or rates, if any;

• the date or dates from which any interest will accrue or the method by which such date or dates will be determined;

6

• the right, if any, to extend the interest payment periods and the duration of any such deferral period, including the maximum consecutive periods during which interest payment periods may be extended;

• whether the amount of payments of principal of (and premium, if any) or interest on the debt securities may be determined with reference to any index, formula or other method, such as one or more currencies, commodities, equity indices or other indices, and the manner of determining the amount of such payments;

• the dates on which we will pay interest on the debt securities and the regular record date for determining who is entitled to the interest payable on any interest payment date;

• the place or places where the principal of (and premium, if any) and interest on the debt securities will be payable, where any debt securities may be surrendered for registration of transfer, exchange or conversion, as applicable, and notices and demands may be delivered to or upon us pursuant to the indenture;

• if we possess the option to do so, the periods within which and the prices at which we may redeem the debt securities, in whole or in part, pursuant to optional redemption provisions, and the other terms and conditions of any such provisions;

• our obligation, if any, to redeem, repay or purchase debt securities by making periodic payments to a sinking fund or through an analogous provision or at the option of holders of the debt securities, and the period or periods within which and the price or prices at which we will redeem, repay or purchase the debt securities, in whole or in part, pursuant to such obligation, and the other terms and conditions of such obligation;

• the denominations in which the debt securities will be issued, if other than denominations of $1,000 and integral multiples of $1,000;

• the portion, or methods of determining the portion, of the principal amount of the debt securities which we must pay upon the acceleration of the maturity of the debt securities in connection with an Event of Default (as described below), if other than the full principal amount;

• the currency, currencies or currency unit in which we will pay the principal of (and premium, if any) or interest, if any, on the debt securities, if not United States dollars;

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

• any deletions from, modifications of or additions to the Events of Default or our covenants with respect to the applicable series of debt securities, and whether or not such Events of Default or covenants are consistent with those contained in the applicable indenture;

• any limitation on our ability to incur debt, redeem stock, sell our assets or other restrictions;

• the application, if any, of the terms of the indenture relating to defeasance and covenant defeasance (which terms are described below) to the debt securities;

• whether the subordination provisions summarized below or different subordination provisions will apply to the debt securities;

• the terms, if any, upon which the holders may convert or exchange the debt securities into or for our common stock, preferred stock or property;

• whether any of the debt securities will be issued in global form and, if so, the terms and conditions upon which global debt securities may be exchanged for certificated debt securities;

• any change in the right of the trustee or the requisite holders of debt securities to declare the principal amount thereof due and payable because of an Event of Default;

• the depositary for global or certificated debt securities;

7

• any special tax implications of the debt securities;

• any trustees, authenticating or paying agents, transfer agents or registrars or other agents with respect to the debt securities;

• any other terms of the debt securities not inconsistent with the provisions of the indentures, as amended or supplemented;

• to whom any interest on any debt security shall be payable, if other than the person in whose name the security is registered, on the record date for such interest, the extent to which, or the manner in which, any interest payable on a temporary global debt security will be paid if other than in the manner provided in the applicable indenture;

• if the principal of or any premium or interest on any debt securities of the series is to be payable in one or more currencies or currency units other than as stated, the currency, currencies or currency units in which it shall be paid and the periods within and terms and conditions upon which such election is to be made and the amounts payable (or the manner in which such amount shall be determined); and

• if the principal amount payable at the stated maturity of any debt security of the series will not be determinable as of any one or more dates prior to the stated maturity, the amount which shall be deemed to be the principal amount of such securities as of any such date for any purpose, including the principal amount thereof which shall be due and payable upon any maturity other than the stated maturity or which shall be deemed to be outstanding as of any date prior to the stated maturity (or, in any such case, the manner in which such amount deemed to be the principal amount shall be determined). Unless otherwise specified in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange. Unless otherwise specified in the applicable prospectus supplement, debt securities will be issued in fully-registered form without coupons.

Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. The applicable prospectus supplement will describe the federal income tax consequences and special considerations applicable to any such debt securities. The debt securities may also be issued as indexed securities or securities denominated in foreign currencies, currency units or composite currencies, as described in more detail in the prospectus supplement relating to any of the particular debt securities. The prospectus supplement relating to specific debt securities will also describe any special considerations and certain additional tax considerations applicable to such debt securities.

Subordination

The prospectus supplement relating to any offering of subordinated debt securities will describe the specific subordination provisions. However, unless otherwise noted in the prospectus supplement, subordinated debt securities will be subordinate and junior in right of payment to any existing Senior Indebtedness.

Under the subordinated indenture, “Senior Indebtedness” means all amounts due on obligations in connection with any of the following, whether outstanding at the date of execution of the subordinated indenture or thereafter incurred or created:

• the principal of (and premium, if any) and interest due on our indebtedness for borrowed money and indebtedness evidenced by securities, debentures, bonds or other similar instruments issued by us;

• all of our capital lease obligations;

• any of our obligations as lessee under leases required to be capitalized on the statement of financial condition of the lessee under generally accepted accounting principles;

• all of our obligations for the reimbursement on any letter of credit, banker’s acceptance, security purchase facility or similar credit transaction;

8

• all of our obligations in respect of interest rate swap, cap or other agreements, interest rate future or options contracts, currency swap agreements, currency future or option contracts and other similar agreements;

• all obligations of the types referred to above of other persons for the payment of which we are responsible or liable as obligor, guarantor or otherwise; and

• all obligations of the types referred to above of other persons secured by any lien on any property or asset of ours (whether or not such obligation is assumed by us).

However, Senior Indebtedness does not include:

• any indebtedness which expressly provides that such indebtedness shall not be senior in right of payment to the subordinated debt securities, or that such indebtedness shall be subordinated to any other of our indebtedness, unless such indebtedness expressly provides that such indebtedness shall be senior in right of payment to the subordinated debt securities;

• any of our indebtedness in respect of the subordinated debt securities;

• any indebtedness or liability for compensation to employees, for goods or materials purchased in the ordinary course of business or for services;

• any of our indebtedness to any subsidiary; and

• any liability for federal, state, local or other taxes owed or owing by us.

Senior Indebtedness shall continue to be Senior Indebtedness and be entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of such Senior Indebtedness.

Unless otherwise noted in the accompanying prospectus supplement, if we default in the payment of any principal of (or premium, if any) or interest on any Senior Indebtedness when it becomes due and payable, whether at maturity or at a date fixed for prepayment or by declaration or otherwise, then, unless and until such default is cured or waived or ceases to exist, we will make no direct or indirect payment (in cash, property, securities, by set-off or otherwise) in respect of the principal of or interest on the subordinated debt securities or in respect of any redemption, retirement, purchase or other requisition of any of the subordinated debt securities.

In the event of the acceleration of the maturity of any subordinated debt securities, the holders of all senior debt securities outstanding at the time of such acceleration, subject to any security interest, will first be entitled to receive payment in full of all amounts due on the senior debt securities before the holders of the subordinated debt securities will be entitled to receive any payment of principal (and premium, if any) or interest on the subordinated debt securities.

If any of the following events occurs, we will pay in full all Senior Indebtedness before we make any payment or distribution under the subordinated debt securities, whether in cash, securities or other property, to any holder of subordinated debt securities:

• any dissolution or winding-up or liquidation or reorganization of BlackRock, whether voluntary or involuntary or in bankruptcy, insolvency or receivership;

• any general assignment by us for the benefit of creditors; or

• any other marshaling of our assets or liabilities.

In such event, any payment or distribution under the subordinated debt securities, whether in cash, securities or other property, which would otherwise (but for the subordination provisions) be payable or deliverable in respect of the subordinated debt securities, will be paid or delivered directly to the holders of Senior Indebtedness in accordance with the priorities then existing among such holders until all Senior Indebtedness has been paid in

9

full. If any payment or distribution under the subordinated debt securities is received by the trustee of any subordinated debt securities in contravention of any of the terms of the subordinated indenture and before all the Senior Indebtedness has been paid in full, such payment or distribution or security will be received in trust for the benefit of, and paid over or delivered and transferred to, the holders of the Senior Indebtedness at the time outstanding in accordance with the priorities then existing among such holders for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all such Senior Indebtedness in full.

The subordinated indenture does not limit the issuance of additional Senior Indebtedness.

Consolidation, Merger, Sale of Assets and Other Transactions

We may not (i) merge with or into or consolidate with another corporation or sell, assign, transfer, lease or convey all or substantially all of our properties and assets to, any other corporation other than a direct or indirect wholly owned subsidiary of ours, and (ii) no corporation may merge with or into or consolidate with us or, except for any direct or indirect wholly owned subsidiary of ours, sell, assign, transfer, lease or convey all or substantially all of its properties and assets to us, unless:

• we are the surviving corporation or the corporation, partnership or trust formed by or surviving such merger or consolidation or to which such sale, assignment, transfer, lease or conveyance has been made, if other than us, is organized under the laws of the United States, any state of the United States or the District of Columbia and has expressly assumed by supplemental indenture all of our obligations under the indentures;

• immediately after giving effect to such transaction and treating any indebtedness which becomes an obligation of the Company or any subsidiary as a result of such transaction as having been incurred by the Company or such Subsidiary at the time of such transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing;

• if properties or assets of the Company would become subject to a mortgage, pledge, lien, security interest or other encumbrance not permitted by the indentures, we take such steps as shall be necessary effectively to secure the debt securities equally and ratably with (or prior to) all indebtedness secured thereby; and

• we deliver to the trustee an officers’ certificate stating that such consolidation, merger, conveyance, transfer or lease comply with the indentures and that all conditions precedent herein provided for relating to such transaction have been complied with and, if a supplemental indenture is required in connection with such transaction, an officers’ certificate and an opinion of counsel stating that such supplemental indenture complies with the indentures.

Events of Default, Notice and Waiver

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

• our failure to pay any interest on any debt security of such series when due and payable, continued for 30 days;

• our failure to pay principal (or premium, if any) on any debt security of such series when due, regardless of whether such payment became due because of maturity, redemption, acceleration or otherwise, or is required by any sinking fund established with respect to such series;

• our failure to observe or perform any other of our covenants or agreements with respect to such debt securities for 60 days after we receive notice of such failure;

• certain events of bankruptcy, insolvency or reorganization of BlackRock; and

• any other Event of Default provided with respect to securities of that series.

10

If an Event of Default with respect to any debt securities of any series outstanding under either of the indentures shall occur and be continuing, the trustee under such indenture or the holders of at least 25% in aggregate principal amount of the debt securities of that series outstanding may declare, by notice as provided in the applicable 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 either 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 such 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 is required within 90 days after the occurrence of a default (which is known to the trustee and is continuing), with respect to the debt securities of any series (without regard to any grace period or notice requirements), to give to the holders of the debt securities of such series notice of such default.

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 indentures at the request of the holders of the debt 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 either 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 applicable 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 either of the indentures (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 applicable indenture, (ii) the holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding under such indenture shall have requested the trustee to institute such action and offered to the trustee reasonable indemnity 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.

We are required to furnish annually to the trustee statements as to our compliance with all conditions and covenants under each indenture.

11

Discharge, Defeasance and Covenant Defeasance

We may discharge or defease our obligations under the indentures as set forth below, unless otherwise indicated in the applicable prospectus supplement.

We may discharge certain obligations to holders of any series of debt securities issued under either the senior indenture or the subordinated indenture that have not already been delivered to the trustee for cancellation and which have either become due and payable or are by their terms due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the trustee money in an amount sufficient to pay and discharge the entire indebtedness on such debt securities not previously delivered to the trustee for cancellation, for principal and any premium 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 we have paid all other sums payable under the applicable indenture.

If indicated in the applicable prospectus supplement, we may elect either (i) to defease and be discharged from any and all obligations with respect to the debt securities of or within any series (except as otherwise provided in the relevant indenture) (“defeasance”) or (ii) to be released from our obligations with respect to certain covenants applicable to the debt securities of or within any series (“covenant defeasance”), upon the deposit with the relevant indenture 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, we must deliver to the trustee an opinion of counsel to the effect that the holders of such debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of defeasance under clause (i) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable federal income tax law occurring after the date of the relevant indenture. In addition, in the case of either defeasance or covenant defeasance, we shall have delivered to the trustee (i) an officers’ certificate to the effect that the relevant debt securities exchange(s) have informed us that neither such debt securities nor any other debt securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit and (ii) an officers’ certificate and an opinion of counsel, each stating that all conditions precedent with respect to such defeasance or covenant defeasance have been complied with.

We may exercise our defeasance option with respect to such debt securities notwithstanding our prior exercise of our covenant defeasance option.

Modification and Waiver

Under the indentures, we and the applicable trustee may supplement the indentures for certain purposes which would not materially adversely affect the interests or rights of the holders of debt securities of a series without the consent of those holders. We and the applicable trustee may also modify the indentures or any supplemental indenture in a manner that affects the interests or rights of the holders of debt securities with the consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each affected series issued under the indenture. However, the indentures require the consent of each holder of debt securities that would be affected by any modification which would:

• change the fixed maturity of any debt securities of any series, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof;

• reduce the amount of principal of an original issue discount debt security or any other debt security payable upon acceleration of the maturity thereof;

12

• change the currency in which any debt security or any premium or interest is payable;

• impair the right to enforce any payment on or with respect to any debt security;

• impair the right to enforce any payment on or with respect to any debt security;

• reduce the percentage in principal amount of outstanding debt securities of any series, the consent of whose holders is required for modification or amendment of the indentures or for waiver of compliance with certain provisions of the indentures or for waiver of certain defaults; or

• modify any of the above provisions.

The indentures permit the holders of at least a majority in aggregate principal amount of the outstanding debt securities of any series issued under the indenture which is affected by the modification or amendment to waive our compliance with certain covenants contained in the indentures.

Payment and Paying Agents

Unless otherwise indicated in the applicable prospectus supplement, payment of interest on a debt security on any interest payment date will be made to the person in whose name a debt security is registered at the close of business on the record date for the interest.

Unless otherwise indicated in the applicable prospectus supplement, principal, interest and premium on the debt securities of a particular series will be payable at the office of such paying agent or paying agents as we may designate for such purpose from time to time. Notwithstanding the foregoing, at our option, payment of any interest may be made by check mailed to the address of the person entitled thereto as such address appears in the security register.

Unless otherwise indicated in the applicable prospectus supplement, a paying agent designated by us will act as paying agent for payments with respect to debt securities of each series. All paying agents initially designated by us for the debt securities of a particular series will be named in the applicable prospectus supplement. We may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, except that we will be required to maintain a paying agent in each place of payment for the debt securities of a particular series.

All moneys paid by us to a paying agent or held by us in trust for the payment of the principal, interest or premium on any debt security which remain unclaimed at the end of two years after such principal, interest or premium has become due and payable will be repaid to us upon request, and the holder of such debt security thereafter may look only to us for payment thereof.

Denominations, Registrations and Transfer

Unless an accompanying prospectus supplement states otherwise, debt securities will be represented by one or more global certificates registered in the name of a nominee for The Depository Trust Company, or DTC. In such case, each holder’s beneficial interest in the global securities will be shown on the records of DTC and transfers of beneficial interests will only be effected through DTC’s records.

A holder of debt securities may only exchange a beneficial interest in a global security for certificated securities registered in the holder’s name if:

• DTC notifies us that it is unwilling or unable to continue serving as the depositary for the relevant global securities or DTC ceases to maintain certain qualifications under the Exchange Act and no successor depositary has been appointed for 90 days; or

• we determine, in our sole discretion, that the global security shall be exchangeable.

13

If debt securities are issued in certificated form, they will only be issued in the minimum denomination specified in the accompanying prospectus supplement and integral multiples of such denomination. Transfers and exchanges of such debt securities will only be permitted in such minimum denomination. Transfers of debt securities in certificated form may be registered at the trustee’s corporate office or at the offices of any paying agent or trustee appointed by us under the indentures. Exchanges of debt securities for an equal aggregate principal amount of debt securities in different denominations may also be made at such locations.

Governing Law

The indentures and debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York, without regard to its principles of conflicts of laws.

Trustee

The trustee under the indentures is The Bank of New York Mellon.

Conversion or Exchange Rights

The prospectus supplement will describe the terms, if any, on which a series of debt securities may be convertible into or exchangeable for our common stock, preferred stock or other debt securities issued by us. These terms will include provisions as to whether conversion or exchange is mandatory, at the option of the holder or at our option. These provisions may allow or require the number of shares of our common stock, shares of preferred stock or debt securities to be received by the holders of such series of debt securities to be adjusted.

If so indicated in the prospectus supplement, the terms of any such series may differ from the terms set forth below.

General. The board of directors is authorized to provide for the issuance of shares of preferred stock in one or more classes or series, to establish from time to time the number of shares to be included in such class or series, and to fix the designations, voting powers (if any), privileges, preferences and relative participating, optional or other special rights of the shares of each such class or series and the qualifications, limitations and restrictions thereon.

• the rate of any dividends (or method of determining the dividends) payable to the holders of the shares of such class or series, any conditions upon which such dividends are payable, the form of payment thereof (whether cash, our securities, securities of another person or other assets) and the date or dates or the method for determining the date or dates upon which such dividends shall be payable;

Anti-Takeover Considerations

The Delaware General Corporation Law, our certificate of incorporation and our bylaws contain provisions which could serve to discourage or to make more difficult a change in control of us without the support of our 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.

17

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 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 the 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. Our 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 our board of directors.

Meetings of Stockholders

Our amended and 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, or any committee of the board of directors that has the power to call such meetings. No stockholder may call a special meeting.

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. Our 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.

Our amended and 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.

Our 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

Our directors are elected annually for terms of one year.

19
