RISK FACTORS

An investment in our common stock is subject to certain risks. You should carefully consider the following risk factors and other information contained in this prospectus supplement, in the documents incorporated by reference in this prospectus supplement and in the accompanying prospectus, including our Annual Report on Form 10-K filed with the SEC on February 26, 2018 and our Quarterly Report on Form 10-Q filed with the SEC on July 25, 2018, as supplemented or updated by our other filings with the SEC, before deciding whether this investment is suited to your particular circumstances.

Risks Relating to Our Common Stock

Our stock price will fluctuate.

Significant fluctuations in the market price and trading volume of our common stock may result not only from general stock market conditions but also from a change in sentiment in the market regarding our operations, business prospects, future funding or this offering. In addition to the risk factors discussed above, the price and volume volatility of our common stock may be affected by:

There may be future sales or other dilution of our equity, which may adversely affect the market price of our common stock.

Except as described under the heading “Underwriting,” we are not restricted from issuing additional common stock, including any securities that are convertible into or exchangeable for, or that represent the right to receive, common stock. The market price of our common stock could decline as a result of sales of shares of our common stock made after this offering or the perception that such sales could occur.

Our board of directors is authorized to issue additional classes or series of preferred stock without any action on the part of the stockholders. The board of directors also has the power, without stockholder approval, to set the terms of any such classes or series of preferred stock that may be issued, including voting rights, dividend rights, and preferences over our common stock with respect to dividends or upon our dissolution, winding-up and liquidation and other terms. If we issue preferred stock in the future that has a preference over our common stock with respect to the payment of dividends or upon our liquidation, dissolution, or winding up, or if we issue preferred stock with voting rights that dilute the voting power of our common stock, the rights of holders of our common stock or the market price of our common stock could be adversely affected.

S-9

Anti-takeover provisions of applicable law could negatively impact our stockholders.

The Bank Holding Company Act requires any “bank holding company” as defined in the Bank Holding Company Act, to obtain the approval of the Federal Reserve Board prior to the acquisition of 5% or more of our common stock. Any person, other than a bank holding company, is required to obtain prior approval of the Federal Reserve Board to acquire 10% or more of our common stock under the Change in Bank Control Act. Any holder of 25% or more of our common stock, or a holder of 5% or more if such holder otherwise exercises a “controlling influence” over us, is subject to regulation as a bank holding company under the Bank Holding Company Act. Chapter 167A of the General Laws of Massachusetts requires any “bank holding company,” as defined in Chapter 167A, to obtain prior approval of the board of bank incorporation before (1) acquiring 5% or more of our common stock, (2) acquiring all or substantially all of our assets or (3) merging or consolidating with us.

S-10

USE OF PROCEEDS

The net proceeds from this offering are expected to be approximately $1.15 billion, after deducting estimated offering expenses and underwriting discount.

We intend to use the net proceeds of this offering to fund a portion of the cash consideration payable for, and certain costs associated with, the Charles River Acquisition, which we expect will occur in the fourth quarter of 2018. Pending completion of the acquisition, we may invest the net proceeds of the offering in short-term bank deposits or invest them in interest-bearing, investment-grade securities. Completion of this offering is not contingent upon completion of the Charles River Acquisition.

If the Charles River Acquisition is not completed, we will use the net proceeds of the offering for general corporate purposes, which may include, without limitation, working capital, capital expenditures, investments in or loans to our subsidiaries, refinancing of outstanding indebtedness, refinancing of outstanding capital securities, share repurchases (including, but not limited to, repurchases of our common stock), dividends, funding potential future acquisitions and satisfaction of other obligations. The precise amounts and timing of these uses of proceeds will depend on the funding requirements of us and our subsidiaries.

S-11

PRICE RANGE OF COMMON STOCK AND DIVIDENDS

As of July 20, 2018, there were approximately 2,554 shareholders of record. The following table provides the high and low sales price per share during the periods indicated, as reported on the New York Stock Exchange, and dividends declared per share of our common stock during such periods.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS FOR NON-U.S. HOLDERS OF COMMON STOCK

The following is a discussion of material U.S. federal income tax considerations relating to the ownership and disposition of our common stock by a non-U.S. holder. For purposes of this discussion, the term “non-U.S. holder” means a beneficial owner (other than a partnership or other pass-through entity) of our common stock that is not, for U.S. federal income tax purposes:

This discussion is based on current provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) existing and proposed U.S. Treasury Regulations promulgated thereunder, current administrative rulings and judicial decisions, all as in effect as of the date of this prospectus supplement and all of which are subject to change or to differing interpretation, possibly with retroactive effect. Any change or differing interpretation could alter the tax consequences to non-U.S. holders described in this prospectus supplement. In addition, the Internal Revenue Service, or the IRS, could challenge one or more of the tax consequences described in this prospectus supplement.

We assume in this discussion that each non-U.S. holder holds shares of our common stock as a capital asset (generally, property held for investment). This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular non-U.S. holder in light of that non-U.S. holder’s individual circumstances nor does it address the alternative minimum tax, the Medicare tax on net investment income, any U.S. federal non-income taxes, such as the estate tax, or any aspects of U.S. state, local or non-U.S. taxes. This discussion also does not consider any specific facts or circumstances that may apply to a non-U.S. holder and does not address the special tax rules applicable to particular non-U.S. holders, such as:

In addition, this discussion does not address the tax treatment of partnerships or other entities that are pass-through entities for U.S. federal income tax purposes or persons who hold their common stock through partnerships or other pass-through entities. A partner in a partnership or other pass-through entity that will hold our common stock should consult his, her or its own tax advisor regarding the tax consequences of the acquisition, ownership and disposition of our common stock through a partnership or other pass-through entity, as applicable.

S-13

Prospective non-U.S. holders of our common stock should consult their own tax advisors regarding the U.S. federal, state, local and non-U.S. income and other tax considerations of acquiring, holding and disposing of our common stock.

Distributions on our Common Stock

Distributions on our common stock generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated as a tax-free return of the non-U.S. holder’s investment, up to such holder’s tax basis in the common stock. Any remaining excess will be treated as capital gain, subject to the tax treatment described below under the heading “Gain on Disposition of Common Stock.” Any distributions will also be subject to the discussions below under the headings “Information Reporting and Backup Withholding” and “FATCA.”

Dividends paid to a non-U.S. holder generally will be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence.

Dividends that are treated as effectively connected with a trade or business conducted by a non-U.S. holder within the United States, and, if an applicable income tax treaty so provides, that are attributable to a permanent establishment or a fixed base maintained by the non-U.S. holder within the United States, are generally exempt from the 30% withholding tax if the non-U.S. holder satisfies applicable certification and disclosure requirements. However, such U.S. effectively connected income is taxed on a net income basis at the same U.S. federal income tax rates applicable to U.S. persons (as defined in the Code). Any U.S. effectively connected income received by a non-U.S. holder that is classified as a corporation for U.S. federal income tax purposes may also, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence.

A non-U.S. holder of our common stock who claims the benefit of an applicable income tax treaty between the United States and such holder’s country of residence generally will be required to provide a properly executed IRS Form W-8BEN or W-8BEN-E (or successor form) and satisfy applicable certification and other requirements. Non-U.S. holders are urged to consult their own tax advisors regarding their entitlement to benefits under a relevant income tax treaty and the specific methods available to them to satisfy these requirements.

A non-U.S. holder that is eligible for a reduced rate of U.S. withholding tax under an income tax treaty may obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim with the IRS.

Gain on Disposition of Common Stock

In general (subject to the discussion below under the headings “Information Reporting and Backup Withholding” and “FATCA”), a non-U.S. holder will not be subject to U.S. federal income tax on gain recognized upon such holder’s sale, exchange or other disposition of shares of our common stock unless:

S-14

Information Reporting and Backup Withholding

We must report the gross amount of the distributions on our common stock paid to each non-U.S. holder and the tax withheld, if any, with respect to such distributions annually to the IRS and to each non-U.S. holder. Non-U.S. holders may have to comply with specific certification procedures to establish that the holder is not a U.S. person (as defined in the Code) in order to avoid backup withholding at the applicable rate with respect to dividends on our common stock. Generally, a non-U.S. holder will comply with such procedures if it provides a properly executed IRS Form W-8BEN or W-8BEN-E (or other applicable Form W-8) or otherwise meets documentary evidence requirements for establishing that it is a non-U.S. holder, or otherwise establishes an exemption. Dividends paid to non-U.S. holders subject to withholding of U.S. federal income tax, as described above under the heading “Distributions on our Common Stock,” will generally be exempt from U.S. backup withholding.

Information reporting and backup withholding generally will apply to the proceeds of a disposition of our common stock by a non-U.S. holder effected by or through the U.S. office of any broker, U.S. or foreign, unless the holder certifies its status as a non-U.S. holder and satisfies certain other requirements, or otherwise establishes an exemption. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds to a non-U.S. holder where the transaction is effected outside the United States through a non-U.S. office of a broker. However, for information reporting purposes, dispositions effected through a non-U.S. office of a broker with substantial U.S. ownership or operations generally will be treated in a manner similar to dispositions effected through a U.S. office of a broker. Non-U.S. holders should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.

Copies of information returns may be made available to the tax authorities of the country in which the non-U.S. holder resides or is incorporated under the provisions of a specific treaty or agreement.

Backup withholding is not an additional tax. Rather, any amounts withheld under the backup withholding rules from a payment to a non-U.S. holder can be refunded or credited against the non-U.S. holder’s U.S. federal income tax liability, if any, provided that an appropriate claim is timely filed with the IRS.

FATCA

Provisions of the Code commonly known as the Foreign Account Tax Compliance Act, or FATCA, generally impose a U.S. federal withholding tax at a rate of 30% on dividends, and, after December 31, 2018, on gross proceeds from the sale or other disposition of, our common stock if paid to a foreign entity unless: (i) if the foreign entity is a “foreign financial institution,” the foreign entity undertakes certain due diligence, reporting, withholding, and certification obligations, (ii) if the foreign entity is not a “foreign financial institution,” the foreign entity identifies certain of its U.S. investors, if any, or (iii) the foreign entity is otherwise exempt under FATCA.

S-15

If withholding under FATCA is required on any payment related to our common stock, investors not otherwise subject to withholding (or that otherwise would be entitled to a reduced rate of withholding) on such payment may be required to seek a refund or credit from the IRS. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this section. Non-U.S. holders should consult their own tax advisors regarding the possible implications of FATCA on their investment in our common stock.

The preceding discussion of material U.S. federal income tax considerations is for prospective investors’ information only. It is not legal or tax advice. Prospective investors should consult their own tax advisors regarding the particular U.S. federal, state, local and non-U.S. tax consequences of purchasing, holding and disposing of our common stock, including the consequences of any proposed changes in applicable laws.

S-16

UNDERWRITING

Under the terms and subject to the conditions contained in an underwriting agreement dated July 26, 2018, we have agreed to sell to the underwriter named below, the following number of shares of common stock:

The underwriting agreement provides that, subject to certain conditions, the underwriter is obligated to purchase all the shares of common stock in the offering if any are purchased.

The underwriter proposes to offer the shares of common stock initially at the public offering price on the cover page of this prospectus supplement and to selling group members at that price less a selling concession of up to $0.10 per share. If all the shares are not sold at the price initially offered to the public, the underwriter may change the public offering price and concession and may offer shares from time to time for sale in negotiated transactions or otherwise, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices, subject to receipt and acceptance by the underwriter and subject to its right to reject any order in whole or in part.

The following table summarizes the compensation to the underwriter:

We estimate that the total expenses of this offering, including registration, filing fees, printing fees, legal and accounting expenses, transfer agent and registrar expenses, will be approximately $800,000.

We have agreed not to offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any shares of our common stock or other securities that are substantially similar to the shares, including but not limited to any options or warrants to purchase any shares of our common stock, or any securities convertible into, exchangeable for or that represent the right to receive shares of our common stock or any such substantially similar securities without the prior written consent of the underwriter for a period of 60 days after the date of this prospectus supplement (the “Lock-Up Period”), other than (i) pursuant to equity incentive or stock option plans reported on our proxy statement filed with the SEC on April 5, 2018 or annual report on Form 10-K for the year ended December 31, 2017 or (ii) upon the exercise of an option or a warrant or the conversion or exchange of convertible or exchangeable securities outstanding as of the date of the underwriting agreement. Our officers and directors have agreed to substantially similar restrictions, with exceptions for transfers made (i) pursuant to Rule 10b5-1 trading plans existing on the date of this prospectus supplement, (ii) to pay withholding tax obligations incurred upon the vesting of certain shares or to deliver forfeited shares, (iii) pursuant to any contractual arrangement in effect on the date of this prospectus supplement that provides for our repurchase of certain shares or in connection with termination of employment and (iv) with the prior written consent of the underwriter, among others. We expect a limited number of filings on Form 4 to be made with the SEC pursuant to these exemptions during the Lock-Up Period.

We have agreed to indemnify the underwriter against liabilities under the Securities Act of 1933, as amended (the “Securities Act”), or contribute to payments that the underwriter may be required to make in that respect.

The underwriter and its affiliates may have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They may have received, or may in the future receive, customary fees and commissions for these transactions.

S-17

In addition, in the ordinary course of their business activities, the underwriter and its 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. The underwriter or its affiliates may have a lending relationship with us and may routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, the underwriter or its affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the shares offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the shares offered hereby. The underwriter and its 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 connection with the offering, the underwriter may engage in stabilizing transactions, short sales, covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934 (the “Exchange Act”). Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed specified maximum prices. Short sales involve sales by the underwriter of shares in excess of the number of shares the underwriter is obligated to purchase, which creates a short position. The underwriter may close out any covered short position by purchasing shares in the open market. A short position is more likely to be created if the underwriter is concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering. The underwriter may also impose a penalty bid. This occurs when a broker or dealer repays to the underwriter a portion of the underwriting discount received by it because the underwriter has repurchased shares sold by or for the account of such broker or dealer in short covering transactions.

These stabilizing transactions, short sales, covering transactions and penalty bids may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of the common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. These transactions may be effected on The New York Stock Exchange market or otherwise and, if commenced, may be discontinued at any time.

A prospectus in electronic format may be made available on the web sites maintained by the underwriter and the underwriter may distribute prospectuses electronically. The underwriter may agree to allocate a number of shares for sale to its online brokerage account holders. Internet distributions will be allocated by the underwriter on the same basis as other allocations.

We expect that the shares will be delivered to investors on or about July 31, 2018, which will be the third business day following the date of pricing of the shares (this settlement cycle is being referred to as “T+3”). Under Rule 15c6-1 of the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the shares on the date of pricing will be required to specify an alternative settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the shares who wish to make such trades should consult their own advisors.

The shares are offered for sale in those jurisdictions in the United States, Europe, Asia and elsewhere where it is lawful to make such offers.

Canada

The shares may be sold in Canada 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 shares must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

S-18

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus (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 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 underwriter is not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

European Economic Area

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”) an offer to the public of our common stock may not be made in that Relevant Member State, except that an offer to the public in that Relevant Member State of our common stock may be made at any time under the following exemptions under the Prospectus Directive:

provided that no such offer of shares of our common stock shall result in a requirement for the publication by us or the underwriter of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression an “offer to the public” in relation to our common stock in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and our common shares to be offered so as to enable an investor to decide to purchase our common shares, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression “Prospectus Directive” means Directive 2003/71/EC (as amended), including by Directive 2010/73/EU, and includes any relevant implementing measure in the Relevant Member State.

This European Economic Area selling restriction is in addition to any other selling restrictions set out below.

LEGAL MATTERS

Certain legal matters in connection with the offering of our common stock will be passed upon for us by Wilmer Cutler Pickering Hale and Dorr LLP. The underwriter has been represented by Cravath, Swaine & Moore LLP.

EXPERTS

The consolidated financial statements of State Street Corporation appearing in State Street Corporation’s Annual Report on Form 10-K for the year ended December 31, 2017, and the effectiveness of State Street Corporation’s internal control over financial reporting as of December 31, 2017, have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

With respect to the unaudited condensed consolidated interim financial information of State Street Corporation for the three-month periods ended March 31, 2018 and March 31, 2017 and the three- and six-month periods ended June 30, 2018 and June 30, 2017, incorporated by reference herein, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated May 3, 2018 and July 25, 2018, included in State Street Corporation’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2018 and June 30, 2018, respectively, incorporated by reference herein, state that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act for their report on the unaudited interim financial information because that report is not a “report” or a “part” of the Registration Statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Securities Act.

This prospectus and the documents incorporated by reference herein, and other public statements we may make, may contain statements that are considered “forward-looking statements” within the meaning of U.S. securities laws, including statements about our goals and expectations regarding our business, financial and capital condition, results of operations, strategies, financial portfolio performance, dividend and stock purchase programs, outcomes of legal proceedings, market growth, acquisitions, joint ventures and divestitures, cost savings and transformation initiatives, client growth and new technologies, services and opportunities, as well as industry, regulatory, economic and market trends, initiatives and developments, the business environment and other matters that do not relate strictly to historical facts. Terminology such as “plan,” “expect,” “intend,” “objective,” “forecast,” “outlook,” “believe,” “priority,” “anticipate,” “estimate,” “seek,” “may,” “will,” “trend,” “target,” “strategy” and “goal,” or similar statements or variations of such terms, are intended to identify forward-looking statements, although not all forward-looking statements contain such terms.

Forward-looking statements are subject to various risks and uncertainties, which change over time, are based on management’s expectations and assumptions at the time the statements are made, and are not guarantees of future results. Management’s expectations and assumptions, and the continued validity of the forward-looking statements, are subject to change due to a broad range of factors affecting the national and global economies, regulatory environment and the equity, debt, currency and other financial markets, as well as factors specific to State Street and its subsidiaries, including State Street Bank. Factors that could cause changes in the expectations or assumptions on which forward-looking statements are based cannot be foreseen with certainty and include, but are not limited to:

Actual outcomes and results may differ materially from what is expressed in our forward-looking statements and from our historical financial results due to the factors discussed in this section and elsewhere in this prospectus and documents incorporated herein by reference or disclosed in our other SEC filings, including the risk factors discussed in the 2016 Form 10-K. Forward-looking statements in this prospectus and the documents incorporated herein by reference should not be relied on as representing our expectations or beliefs as of any time subsequent to the time this prospectus is filed with the SEC. We undertake no obligation to revise our forward-looking statements after the time they are made. The factors discussed herein are not intended to be a complete statement of all risks and uncertainties that may affect our businesses. We cannot anticipate all developments that may adversely affect our business or operations or our consolidated results of operations, financial condition or cash flows.

Forward-looking statements should not be viewed as predictions, and should not be the primary basis on which investors evaluate State Street. Any investor in State Street should consider all risks and uncertainties disclosed in our SEC filings, described above under “Where You Can Find More Information,” all of which are accessible on the SEC’s website at www.sec.gov or on the “Investor Relations” section of our corporate website at www.statestreet.com.

DESCRIPTION OF DEBT SECURITIES

The senior debt securities will be issued under an indenture dated as of October 31, 2014, between us and U.S. Bank National Association, as senior trustee, which we refer to as the original senior indenture, as supplemented by the first supplemental indenture, dated as of May 8, 2017 between us and the senior trustee, which we refer to as the first senior supplemental indenture. We refer to the original senior indenture as amended by the first senior supplemental indenture as the senior indenture. The original senior indenture and the first senior supplemental indenture are filed as exhibits to and incorporated by reference into the registration statement of which this prospectus forms a part.

The subordinated debt securities will be issued under an indenture dated as of October 31, 2014, between us and Wells Fargo Bank, National Association, as subordinated trustee, which we refer to as the original subordinated indenture, as amended by the first supplemental indenture, dated as of November 2, 2017 between us and the subordinated trustee, which we refer to as the first subordinated supplemental indenture. We refer to the original subordinated indenture as amended by the first subordinated supplemental indenture as the subordinated indenture. We refer to the senior indenture and the subordinated indenture, as each may be amended or supplemented from time to time, individually as an indenture and collectively as the indentures. The original subordinated indenture and the first subordinated supplemental indenture are filed as exhibits to and, in the case of the original subordinated indenture, incorporated by reference into the registration statement of which this prospectus forms a part. For purposes of this section entitled “Description of Debt Securities,” references to “State Street,” “we,” “our,” “ours” and “us” relate only to State Street Corporation and not its subsidiaries.

The following summaries of the material terms of the indentures are not complete and are subject to, and are qualified in their entirety by reference to, the specific text of the respective indentures, including the definitions of terms. The following summaries describe the general terms and provisions of the debt securities to be offered by prospectus supplement. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which these general provisions may apply to the debt securities so offered, will be described in the prospectus supplement relating to such offered securities.

The senior debt securities will be unsecured and will rank equally with all other unsecured and unsubordinated indebtedness of State Street. The subordinated debt securities will be unsecured and will be subordinated to all existing and future senior indebtedness as described under “Subordinated Debt Securities—Subordination” beginning on page 19. We are a holding company and conduct substantially all of our operations through subsidiaries. As a result, claims of holders of the debt securities will generally have a junior position to claims of creditors of our subsidiaries, except to the extent that we may be recognized as a creditor of those subsidiaries. In addition, our right to participate as a shareholder in any distribution of assets of any subsidiary (and thus the ability of holders of the debt securities to benefit as our creditors from such distribution) is junior to the rights of creditors of that subsidiary. In addition, dividends, loans and advances from certain of our banking subsidiaries, including State Street Bank, to us and our non-banking subsidiaries are restricted by law.

General

We may issue the debt securities from time to time, without limitation as to aggregate principal amount and in one or more series. We also may, from time to time, incur additional indebtedness that is senior to the debt securities. Neither the indentures nor the debt securities will limit or otherwise restrict the amount of other indebtedness which may be incurred or other securities that may be issued by us or our subsidiaries, including indebtedness that may rank senior to the debt securities.

We may issue debt securities upon the satisfaction of conditions contained in the indentures. The applicable prospectus supplement will include the terms of each series of debt securities being offered, including:

-11-

We may issue debt securities under the indentures upon the exercise of warrants to purchase debt securities. Please see “Description of Warrants.” Nothing in the indentures or in the terms of the debt securities will prohibit the issuance of securities representing subordinated indebtedness that is senior or junior to the subordinated debt securities.

-12-

Debt securities may be issued as original issue discount securities that bear no interest or interest at a rate which at the time of issuance is below market rates and which will be sold at a substantial discount below their principal amount. In the event that the maturity of any original issue discount security is accelerated, the amount payable to the holder of the original issue discount security upon acceleration will be determined in accordance with the applicable prospectus supplement, the terms of such security and the relevant indenture, but will be an amount less than the amount payable at the maturity of the principal of such original issue discount security. Special federal income tax and other considerations relating to original issue discount securities will be described in the applicable prospectus supplement.

In the event any sinking fund is established for the retirement of debt securities of any series, we may satisfy all or any part of the sinking fund payments with debt securities of such series under certain circumstances and to the extent provided for by the terms of such debt securities.

We will have the ability under the indentures to reopen a previously issued series of debt securities and issue additional debt securities of that series or establish additional terms of the series. We are also permitted to issue additional series of debt securities with the same terms as the previously issued series.

Unless otherwise indicated in the applicable prospectus supplement, the covenants contained in the indentures and the debt securities will not protect holders in the event of a sudden decline in our creditworthiness that might result from a recapitalization, restructuring or other highly leveraged transaction.

Registration and Transfer

Unless otherwise indicated in the applicable prospectus supplement, we will issue each series of debt securities in registered form only, without coupons and in denominations of $1,000 or integral multiples thereof. Holders may present debt securities in registered form for transfer or exchange for other debt securities of the same series at the office or agency of State Street maintained for such purpose.

No service charge will be made for any transfer or exchange of the debt securities but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection with any transfer or exchange.

Payment and Place of Payment

Unless otherwise indicated in the applicable prospectus supplement, we will pay principal of and any premium and interest on the debt securities to the holders of record at the office or agency of State Street maintained for such purpose. However, at our option, we may pay any interest by check mailed to the holders of record of registered debt securities at their registered addresses.

Events of Default under the Senior Indenture

Unless otherwise indicated in the applicable prospectus supplement, the following are events of default under the senior indenture:

No other defaults under or breaches of the senior indenture or any senior debt securities will result in an event of default, whether after notice, the passage of time or otherwise. For example and for the avoidance of

-13-

doubt, the bankruptcy, insolvency or reorganization of State Street Bank, whether in a voluntary or involuntary proceeding, will not constitute a default or event of default under the senior indenture. However, certain events may give rise to a covenant breach, as described below under “—Covenant Breaches.”

Senior debt securities issued by us prior to the date of the first supplemental indenture (the “Pre-2017 Senior Debt”) contain events of default that are different from those set forth above. In particular:

Accordingly, if we fail to pay the principal of, or premium on, any series of Pre-2017 Senior Debt when due, the holders of such senior debt securities would be entitled to declare their securities due and payable immediately, whereas holders of the senior debt securities issued under the senior indenture and offered pursuant to this prospectus would not be entitled to accelerate the senior debt securities offered hereby until 30 days after our failure to pay the principal of, or premium on, the senior debt securities issued under the senior indenture that we are offering pursuant to this prospectus. In addition, holders of the senior debt securities offered pursuant to this prospectus will not have the benefit of the additional events of default described above that are applicable to the Pre-2017 Senior Debt.

Covenant Breaches under the Senior Indenture

Unless otherwise indicated in the applicable prospectus supplement, a “covenant breach” would occur under the senior indenture with respect to a series of senior debt securities upon:

A covenant breach is not an event of default with respect to any senior debt security issued under the senior indenture.

Remedies if an Event of Default or Covenant Breach under the Senior Indenture Occurs

If an event of default under the senior indenture occurs and is continuing for any series of senior debt securities, other than an event of default resulting from a voluntary bankruptcy, insolvency or reorganization of State Street Corporation, the senior trustee or the holders of at least 25% in aggregate principal amount of the outstanding securities of that series may declare the principal amount of all the securities of that series, or any lesser amount provided for in the debt securities of that series, to be due and payable or deliverable immediately. The senior debt securities will automatically be accelerated upon the occurrence of an event of default resulting from a voluntary bankruptcy, insolvency or reorganization of State Street Corporation.

For senior debt securities issued under the senior indenture, acceleration will not be permitted for reasons other than a specified payment default or insolvency event that constitutes an event of default in respect of such

-14-

securities. Except as described below, neither the senior trustee nor any holders of such securities will have any enforcement right or other remedy in respect of covenant breaches (including covenant breaches with respect to the covenant described below under “—Consolidation, Merger and Sale of Assets”).

At any time after the trustee or the holders have accelerated any series of senior debt securities, but before the senior trustee has obtained a judgment or decree for payment of money due, the holders of a majority in aggregate principal amount of outstanding debt securities of that series may, under certain circumstances, rescind and annul such acceleration and any event of default giving rise to such declaration shall not be deemed to have occurred.

The holders of a majority in principal amount of the outstanding senior debt securities of any series may waive a default with respect to that series, except a default:

For the purpose of this paragraph, the term “default” means any event which is, or after notice or lapse of time or both would become, an event of default or a covenant breach in respect of the relevant securities.

In the case of a default in the payment of interest or principal, or premium, if any, that continues for 30 days, State Street will be required, upon the demand of the trustee, to pay to it, for the benefit of the holders of the senior debt securities, the whole amount then due and payable on such debt securities for principal and premium, if any, and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal, and premium, if any, and on any overdue interest, at the rate or rates prescribed in such senior debt securities.

In the case of any event of default or a covenant breach, the trustee may in its discretion proceed to protect and enforce its rights and the rights of the holders of such debt securities by such appropriate judicial proceedings as the trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any such covenant or agreement or in aid of the exercise of any power granted in the indenture, or to enforce any other proper remedy. However, in the case of a covenant breach or any other default that does not constitute an event of default, neither the trustee nor the holders of senior debt securities will be entitled to accelerate the maturity of such senior debt securities—that is, they will not be entitled to declare the principal of such securities to be immediately due and payable because of such covenant breach or other default.

The holders of a majority in principal amount of the outstanding debt securities of a series may direct the time, method and place of conducting any proceeding for any remedy available to the applicable trustee or exercising any trust or power conferred on the trustee with respect to debt securities of that series, provided that any such direction is not in conflict with any rule of law or the indenture and the trustee may take any other action deemed proper by the trustee that is not inconsistent with such direction. Subject to the provisions of the indenture relating to the duties of the trustee, before proceeding to exercise any right or power under the indenture at the direction of the holders, the trustee is entitled to receive from those holders reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in complying with any direction.

No holder of any senior debt security of any series will have the right to institute a proceeding with respect to the indenture or for any remedy thereunder, unless:

-15-

However, any holder of a senior debt security has the absolute right to institute suit for any defaulted payment after the due dates for payment under that debt security.

We are required to furnish to the senior trustee annually a statement as to the performance of our obligations under the senior indenture and as to any default in such performance. For the purpose of this paragraph, the term “default” means any event which is, or after notice or lapse of time or both would become, an event of default or a covenant breach in respect of the relevant securities.

Modification and Waiver

Each indenture may be modified and amended by us and the applicable trustee with the consent of holders of at least a majority in principal amount of each series of debt securities affected. However, without the consent of each holder of any debt security affected, we may not amend or modify any indenture to:

From time to time we and the applicable trustee may, without the consent of the holders of the debt securities, waive or supplement each indenture for specified purposes, including, among other things:

-16-

Consolidation, Merger and Sale of Assets

Unless otherwise indicated in the applicable prospectus supplement, we may consolidate or merge with or into any other corporation, partnership, trust company or trust, and we may convey, transfer or lease all or substantially all of our assets to any corporation, partnership, trust company or trust, provided that (other than in the case of the conveyance, transfer or lease of our properties and assets substantially as an entirety to one or more of our subsidiaries):

-17-

The surviving business entity will succeed to, and be substituted for, us under the senior indenture and, except in the case of a lease, we shall be released from all obligations under the senior indenture and the senior debt securities.

Regarding the Trustees

U.S. Bank National Association is the trustee under the senior indenture. Wells Fargo Bank, National Association is the trustee under the subordinated indenture. We and certain of our subsidiaries, including State Street Bank, maintain banking relations with the trustees in the ordinary course of business.

Limitation Upon Disposition of Voting Stock of State Street Bank

The senior indenture prohibits us and any subsidiary of ours that owns voting stock in State Street Bank, so long as any of the senior debt securities are outstanding, from selling or otherwise disposing of, or granting a security interest in or permitting the issuance of, any voting stock or any security convertible or exercisable into voting stock of State Street Bank or any of our subsidiaries that owns voting stock, or any security convertible or exercisable into voting stock, of State Street Bank, except that this restriction does not apply to dispositions made by us or any subsidiary or issuances if after giving effect to such disposition or issuance and any potential dilution, we (directly or indirectly through one or more subsidiaries) will own in the aggregate at least 80% of the voting stock of State Street Bank free and clear of any security interest.

In addition, the restriction does not apply to:

The subordinated indenture does not contain a similar restriction on our ability to engage in or permit such transactions to occur.

Defeasance

If the prospectus supplement relating to the debt securities of a series so specifies, we may, at our option and at any time, elect to have all of the obligations discharged with respect to the outstanding debt securities of a particular series, except for:

A discharge of this type is referred to as “legal defeasance.”

-18-

In addition, other than our covenant to pay the amounts due and owing with respect to the debt securities of a particular series, we may elect to have our obligations as the issuer of debt securities of any series released with respect to certain covenants, including in the case of the senior indenture, the limitation on the disposition of voting stock of State Street Bank described above, applicable to the debt securities of such series. Thereafter, any failure to comply with those obligations will not constitute a default or event of default (or, with respect to any series of senior debt securities, a covenant breach) with respect to the debt securities of such series. If such a release of our covenants occurs, our failure to perform or a breach of the covenants or warranties defeased will no longer constitute an event of default (or, with respect to any series of senior debt securities, a covenant breach) with respect to those debt securities. A discharge of this type is referred to as “covenant defeasance.”

To exercise either a legal defeasance or a covenant defeasance, certain conditions must be met, including, among other things:

Subordinated Debt Securities

Other than the terms of the subordinated indenture and the subordinated debt securities relating to subordination and events of default, absence of restrictive covenants applicable with respect to subordinated debt securities, and as otherwise described in the prospectus supplement relating to a particular series of subordinated debt securities, the terms of the subordinated indenture and the subordinated debt securities are identical in all material respects to the terms of the senior indenture and senior debt securities.

The subordinated debt securities will be our direct, unsecured obligations. Unless otherwise specified in the applicable prospectus supplement, the subordinated debt securities will rank equally with all of our outstanding subordinated indebtedness that is not specifically stated to be junior to the subordinated debt securities. As of the date of this prospectus, our 3.10% Senior Subordinated Notes Due 2023 (the “2023 Subordinated Notes”) are our only outstanding subordinated debt securities under the subordinated indenture.

Subordination

The subordinated debt securities will be subordinated in right of payment to all senior indebtedness (as defined below). In certain circumstances relating to our liquidation, dissolution, winding up, reorganization, insolvency or similar proceedings, the holders of all senior indebtedness will first be entitled to receive payment in full before the holders of the subordinated debt securities will be entitled to receive any payment on the subordinated debt securities.

-19-

Events of Default under the Subordinated Indenture

Unless otherwise indicated in the applicable prospectus supplement, an event of default with respect to subordinated debt securities under the subordinated indenture is limited to certain events involving the bankruptcy, insolvency or reorganization of State Street Corporation.

Defaults under the Subordinated Indenture

Unless otherwise indicated in the applicable prospectus supplement, the following are “defaults” with respect to subordinated debt securities under the subordinated indenture:

For the avoidance of doubt, the bankruptcy, insolvency or reorganization of State Street Bank, whether in a voluntary or involuntary proceeding, will not constitute a default or event of default under the subordinated indenture although the bankruptcy, insolvency or reorganization of State Street Bank will constitute a default (but not an event of default) with respect to the 2023 Subordinated Notes.

Remedies if an Event of Default or Default under the Subordinated Indenture Occurs

The subordinated debt securities will automatically be accelerated only upon the occurrence of an “event of default” resulting from a voluntary bankruptcy, insolvency or reorganization of State Street Corporation or the consent by State Street Corporation to relief under, or the taking of certain actions by State Street with respect to, certain insolvency laws. If an event of default resulting from the involuntary bankruptcy, insolvency or reorganization of State Street Corporation occurs and is continuing, the subordinated trustee or the holders of at least 25% in aggregate principal amount of the outstanding securities of that series may declare the principal amount of all the securities of that series, or any lesser amount provided for in the debt securities of that series, to be due and payable or deliverable immediately. There will be no right of acceleration of the payment of principal upon any other default, including payment defaults under the subordinated indenture or in the performance of any covenant or agreement in the subordinated indenture or subordinated securities.

In the case of a default (which, for clarity, is different from an “event of default” for the subordinated debt securities) in the payment of interest or principal, or premium, if any, State Street will be required, upon the demand of the subordinated trustee, to pay to it, for the benefit of the holders of the subordinated debt securities, the whole amount then due and payable on such subordinated debt securities for principal, and premium, if any, and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal, and premium, if any, and on any overdue interest, at the rate or rates prescribed in such subordinated debt securities. If we fail to pay such amounts, upon demand, the subordinated trustee may institute a judicial proceeding for the collection of the amounts due and unpaid, to collect such amounts payable. In the case of any default with respect to the subordinated debt securities, the subordinated trustee may in its discretion proceed to protect and enforce its rights and the rights of the holders of the subordinated debt securities by such appropriate judicial proceedings as the trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any such covenant or in aid of the exercise of any power granted in the subordinated indenture, or to enforce any other proper remedy.

-20-

In the event of the acceleration of the maturity of any subordinated debt securities, all senior indebtedness will have to be repaid before any payment can be made on the subordinated debt securities.

In addition, during the continuance of any default in the payment of principal, premium or interest on senior indebtedness, no payment may be made on the subordinated debt securities if notice of such default has been given and certain judicial proceedings commenced or if judicial proceedings are pending in respect of such default.

By reason of this subordination in favor of the holders of senior indebtedness, in the event of an insolvency, our creditors who are not holders of senior indebtedness or the subordinated debt securities may recover proportionately less than holders of senior indebtedness and may recover proportionately more than holders of the subordinated debt securities.

Unless otherwise specified in the prospectus supplement relating to the particular series of subordinated debt securities, senior indebtedness is defined in the subordinated indenture as the principal of, premium, if any, and interest on:

in each case, whether outstanding on the date of this prospectus or thereafter created, assumed or incurred, provided that in each case senior indebtedness shall not include (a) the subordinated debt securities; (b) the 2023 Subordinated Notes; and (c) such other indebtedness of ours as is by its terms expressly stated not to be senior in right of payment to, or to rank pari passu with, the subordinated debt securities or the other securities referred to in clause (b).

The term “indebtedness for money borrowed” means any obligation of ours, or any obligation guaranteed by, us for the repayment of money borrowed, whether or not evidenced by bonds, debentures, notes or other written instruments, and any deferred obligation for the payment of the purchase price of property or assets.

The subordinated indenture does not limit or prohibit the incurrence by us or any of our subsidiaries, including State Street Bank, of additional senior indebtedness or other financial obligations, which may include indebtedness that is senior to the subordinated debt securities, but subordinate to our other obligations.

The subordinated debt securities shall rank equal in right of payment with each other.

The prospectus supplement may further describe or alter the provisions, if any, which may apply to the subordination of the subordinated debt securities of a particular series.

Restrictive Covenants

The subordinated indenture does not contain any significant restrictive covenants. The prospectus supplement relating to a series of subordinated debt securities may describe certain restrictive covenants, if any, to which we may be bound under the subordinated indenture.

Governing Law

Both indentures are, and the senior debt securities and subordinated debt securities will be, governed by and construed in accordance with the laws of the State of New York.

DESCRIPTION OF PREFERRED STOCK

The following summary contains a description of the general terms and provisions of the preferred stock that we may issue. Other terms of any series of preferred stock will be described in the prospectus supplement relating to that series of preferred stock. The terms of any series of preferred stock may differ from the terms described below. Certain provisions of the preferred stock described below and in any prospectus supplement are not complete. You should refer to our Restated Articles of Organization, as amended, and the certificate of designation that will be filed with the SEC in connection with the offering of a particular series of preferred stock. For purposes of this section entitled “Description of Preferred Stock,” references to “State Street,” “we,” “our,” “ours” and “us” relate only to State Street Corporation and not its subsidiaries.

General

Our articles of organization permit our board of directors to authorize the issuance of up to 3,500,000 shares of preferred stock, without par value, in one or more series, without shareholder action. Of such number of shares of preferred stock, 5,000 shares have been designated as Non-Cumulative Perpetual Preferred Stock, Series C, or the series C preferred stock, 7,500 shares have been designated as Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series D, or the series D preferred stock, 7,500 shares have been designated as Non-Cumulative Perpetual Preferred Stock, Series E, or the series E preferred stock, 7,500 shares have been designated as Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series F, or the series F preferred stock, and 5,000 shares have been designated as Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series G, or the series G preferred stock. The board of directors can determine the rights, preferences and limitations of each series. Therefore, without shareholder approval, our board of directors can authorize the issuance of preferred stock with voting, conversion and other rights that could dilute the voting power and other rights of our common stockholders. 5,000 shares of our series C preferred stock, 7,500 shares of our series D preferred stock, 7,500 shares of our series E preferred stock, 7,500 shares of our series F preferred stock and 5,000 shares of our series G preferred stock were outstanding as of September 30, 2017. We redeemed all of the issued and outstanding shares of our series B preferred stock in 2009 and all of the issued and outstanding shares of our series A preferred stock in 2012.

The preferred stock will have the terms described below unless otherwise provided in the prospectus supplement relating to a particular series of the preferred stock. You should read the prospectus supplement relating to the particular series of the preferred stock being offered for specific terms, including:

The preferred stock will, when issued, be fully paid and nonassessable. Unless otherwise specified in the prospectus supplement, each series of the preferred stock will rank equally as to dividends and liquidation rights

-22-

in all respects with each other series of preferred stock. The rights of holders of shares of each series of preferred stock will be subordinate to those of our general creditors.

One of the effects of authorized but unissued and unreserved shares of capital stock may be to make it more difficult or to discourage an attempt by a potential acquirer to obtain control of our company by means of a merger, tender offer, proxy contest or otherwise. The issuance of these shares of capital stock may defer or prevent a change in control of our company without any further shareholder action.

As described under “Description of Depositary Shares,” we may, at our option, with respect to any series of the preferred stock, elect to offer fractional interests in shares of preferred stock, and provide for the issuance of depositary receipts representing depositary shares, each of which will represent a fractional interest in a share of the series of the preferred stock. The fractional interest will be specified in the prospectus supplement relating to a particular series of the preferred stock.

Rank

All series of our outstanding preferred stock have, and any other series of preferred stock that we may issue in the future will have, preference over our common stock with respect to the payment of dividends and the distribution of assets in the event of our liquidation, winding up or dissolution. In particular, unless otherwise specified in the prospectus supplement, the preferred stock will, with respect to the priority of the payment of dividends and the distribution of assets upon voluntary or involuntary liquidation, dissolution or winding up, rank:

Unless the terms of any preferred stock specifically provide that it will rank junior or senior to our series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock or series G preferred stock, each such series of preferred stock will be parity securities with respect to such preferred stock. The consent of at least two-thirds of the outstanding shares of each of our series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock and series G preferred stock, voting separately as separate classes, is required for us to authorize any class or series of capital stock that would rank senior to such series of preferred stock with respect to the payment of dividends or the distribution of assets on our liquidation, winding up or dissolution.

Dividends

Holders of the preferred stock of each series will be entitled to receive, when, as and if declared by our board of directors, cash dividends at such rates and on such dates described in the prospectus supplement. Different series of preferred stock may be entitled to dividends at different rates or based on different methods of calculation. The dividend rate may be fixed or variable or both. Dividends will be payable to the holders of record as they appear on our stock books on record dates fixed by our board of directors, as specified in the applicable prospectus supplement.

Dividends on any series of the preferred stock may be cumulative or non-cumulative, as described in the applicable prospectus supplement. If our board of directors does not declare a dividend payable on a dividend payment date on any series of non-cumulative preferred stock, then the holders of that non-cumulative preferred

-23-

stock will have no right to receive a dividend for that dividend payment date, and we will have no obligation to pay the dividend accrued for that period, whether or not dividends on that series are declared payable on any future dividend payment dates. Dividends on any series of cumulative preferred stock will accrue from the date we initially issue shares of such series or such other date specified in the applicable prospectus supplement.

No dividends may be declared or paid or funds set apart for the payment of any dividends on any parity securities unless dividends have been paid or set apart for payment on the preferred stock. If full dividends are not paid, the preferred stock will share dividends pro rata with the parity securities. No dividends may be declared or paid or funds set apart for the payment of dividends on any junior securities unless full dividends will have been paid or declared and a sum sufficient for the payment set apart for payment on the preferred stock (i) in the case of a series of preferred stock with cumulative dividend rights, for all dividend periods, (ii) in the case of the series C preferred stock, for the then current dividend period and (iii) in the case of the series D preferred stock, series E preferred stock, series F preferred stock, series G preferred stock, and any other series of preferred stock without cumulative dividend rights, for the then most recently completed dividend period.

Our ability to pay dividends on our preferred stock is also subject to regulations and policies established by the Federal Reserve, including its capital planning requirements.

Rights Upon Liquidation

If we dissolve, liquidate or wind up our affairs, either voluntarily or involuntarily, the holders of each series of preferred stock, including any parity securities, will be entitled to receive, before any payment or distribution of assets is made to holders of junior securities, liquidating distributions in the amount described in the prospectus supplement relating to that series of the preferred stock, plus an amount equal to accrued and unpaid dividends and, if the series of the preferred stock is cumulative, for all dividend periods prior to that point in time. If the amounts payable with respect to the preferred stock of any series and any other parity securities are not paid in full, the holders of the preferred stock of that series and of the parity securities will share proportionately in the distribution of our assets in proportion to the full liquidation preferences to which they are entitled. After the holders of preferred stock and the parity securities are paid in full, they will have no right or claim to any of our remaining assets.

Because we are a bank holding company, our rights, the rights of our creditors and the rights of our stockholders, including the holders of any series of preferred stock offered by this prospectus, to participate in the assets of any subsidiary upon the subsidiary’s liquidation or recapitalization may be subject to the prior claims of the subsidiary’s creditors except to the extent that we may ourselves be a creditor with recognized claims against the subsidiary.

Redemption

A series of preferred stock may be redeemable, in whole or in part, at our option with prior Federal Reserve approval. In addition, a series of preferred stock may be subject to mandatory redemption pursuant to a sinking fund or otherwise. Any redemption provisions that may apply to a series of preferred stock, including the redemption dates and the redemption prices for that series, will be described in the prospectus supplement.

In the event of partial redemptions of preferred stock, whether by mandatory or optional redemption, our board of directors will determine the method for selecting the shares to be redeemed, which may be by lot or pro rata or by any other method determined to be equitable.

On or after a redemption date, unless we default in the payment of the redemption price, dividends will cease to accrue on shares of preferred stock called for redemption. In addition, all rights of holders of the shares will terminate except for the right to receive the redemption price.

-24-

Unless otherwise specified in the applicable prospectus supplement for any series of preferred stock, if any dividends on any other series of preferred stock ranking equally as to payment of dividends and liquidation rights with such series of preferred stock are in arrears, no shares of any such series of preferred stock may be redeemed, whether by mandatory or optional redemption, unless all shares of preferred stock are redeemed, and we will not purchase any shares of such series of preferred stock. This requirement, however, will not prevent us from acquiring such shares pursuant to a purchase or exchange offer made on the same terms to holders of all such shares outstanding.

Under current regulations, bank holding companies generally may not exercise any option to redeem shares of preferred stock included as Tier 1 capital without the prior approval of the Federal Reserve. The factors the Federal Reserve currently considers in evaluating a proposed redemption by a bank holding company include, among other things, the capital plans and stress tests submitted by the bank holding company, the bank holding company’s ability to meet and exceed minimum regulatory capital ratios under stressed scenarios, its expected sources and uses of capital over the planning horizon (generally a period of two years) under baseline and stressed scenarios, and any potential impact of changes to its business plan and activities on its capital adequacy and liquidity, although the Federal Reserve may change these factors at any time.

Voting Rights

Unless otherwise described in the applicable prospectus supplement, holders of the preferred stock will have no voting rights except as set forth below or as otherwise required by law or in our articles of organization.

In addition, if the dividends on the series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock, series G preferred stock or any preferred stock designated as ranking equally with each such series of preferred stock as to the payment of dividends (whether non-cumulative or cumulative) and with like voting rights, referred to as voting parity securities, have not been paid,

then the authorized number of directors then constituting our board of directors will be increased by two. Holders of the series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock and series G preferred stock, together with the holders of voting parity securities, voting as a single class, will be entitled to elect the two additional members of our board of directors, referred to as the preferred stock directors. The election of any preferred stock director is subject to the qualification that the election would not cause us to violate the corporate governance requirement of the New York Stock Exchange (or any other exchange on which our securities may be listed) that listed companies must have a majority of independent directors. The election of any preferred stock director is also subject to the qualification that at no time shall our board of directors include more than two preferred stock directors (including all directors that holders of any series of voting parity securities are entitled to elect pursuant to like voting rights). In the event the holders of the series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock and series G preferred stock, and the holders of voting parity securities are entitled to elect preferred stock directors, such directors shall be initially elected following a nonpayment event described above only at a special meeting called at the request of the holders of series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock and series G preferred stock, and each other series of voting parity securities then outstanding (unless the request for a special meeting is received less than 90 days before the date fixed for the next annual or special meeting of shareholders, in which event the election shall be held only at such next annual or special meeting of shareholders), and at each subsequent annual meeting of shareholders. When dividends have been paid in full on

-25-

the series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock and series G preferred stock, and any non-cumulative voting parity securities for dividend periods, whether or not consecutive, equivalent to at least one year after a nonpayment event and all dividends on any cumulative voting parity securities have been paid in full, then the right of the holders of the series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock and series G preferred stock to elect the preferred stock directors shall cease (subject to revesting of such voting rights in the case of any future nonpayment event). Upon the termination of these rights of the holders of preferred stock and voting parity securities to vote for preferred stock directors, the terms of office of the preferred stock directors shall forthwith terminate and the number of authorized directors of State Street will be reduced by the number of preferred stock directors that the holders of preferred stock and voting parity securities had been entitled to elect.

Under regulations adopted by the Federal Reserve, if the holders of one or more series of preferred stock are or become entitled to vote for the election of directors, such series entitled to vote for the same director(s) will be deemed a class of voting securities and a company holding 25% or more of the series, or that otherwise exercises a “controlling influence” over us, will be subject to regulation as a bank holding company under the Bank Holding Company Act of 1956, as amended (the “BHC Act”). In addition, if the series is/are deemed to be a class of voting securities, any other bank holding company will be required to obtain the prior approval of the Federal Reserve under the BHC Act to acquire or retain 5% or more of that series, and any other person (other than a bank holding company) will be required to obtain the non-objection of the Federal Reserve under the Change in Bank Control Act of 1978, as amended, to acquire or retain 10% or more of that series.

While we do not believe the preferred stock are considered “voting securities” currently, holders of the preferred stock should consult their own counsel with regard to regulatory implications. A holder or group of holders may also be deemed to control us if they own more than one-third of our total equity, both voting and non-voting, aggregating all shares held by the holders across all classes of stock.

Exchangeability

The holders of shares of preferred stock of any series may be required at any time or at maturity to exchange those shares for our debt securities. The applicable prospectus supplement will specify the terms of any such exchange.

Transfer Agent and Registrar

Unless otherwise indicated in the applicable prospectus supplement, American Stock Transfer & Trust Company, LLC will be the transfer agent, dividend and redemption price disbursement agent and registrar for shares of each series of the preferred stock.

-26-

DESCRIPTION OF DEPOSITARY SHARES

General

We may, at our option, elect to offer fractional shares of preferred stock, which we call depositary shares, rather than full shares of preferred stock. If we do, we will issue to the public receipts, called depositary receipts, for depositary shares, each of which will represent a fraction, to be described in the applicable prospectus supplement, of a share of a particular series of preferred stock. Unless otherwise provided in the prospectus supplement, each owner of a depositary share will be entitled, in proportion to the applicable fractional interest in a share of preferred stock represented by the depositary share, to all the rights and preferences of the preferred stock represented by the depositary share. Those rights include dividend, voting, redemption, conversion and liquidation rights. For purposes of this section entitled “Description of Depositary Shares,” references to “State Street,” “we,” “our,” “ours” and “us” relate only to State Street Corporation and not its subsidiaries.

The shares of preferred stock underlying the depositary shares will be deposited with a bank or trust company selected by us to act as depositary under a deposit agreement between us, the depositary and the holders of the depositary receipts. The depositary will be the transfer agent, registrar and dividend disbursing agent for the depositary shares.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Holders of depositary receipts agree to be bound by the deposit agreement, which requires holders to take certain actions such as filing proof of residence and paying certain charges.

The summary of terms of the depositary shares contained in this prospectus is not complete. You should refer to the form of the deposit agreement, our articles of organization and the certificate of designation for the applicable series of preferred stock that are, or will be, filed with the SEC.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions, if any, received in respect of the preferred stock underlying the depositary shares to the record holders of depositary shares in proportion to the numbers of depositary shares owned by those holders on the relevant record date. The relevant record date for depositary shares will be the same date as the record date for the underlying preferred stock.

If there is a distribution other than in cash, the depositary will distribute property (including securities) received by it to the record holders of depositary shares, unless the depositary determines that it is not feasible to make the distribution. If this occurs, the depositary may, with our approval, adopt another method for the distribution, including selling the property and distributing the net proceeds from the sale to the holders.

Liquidation Preference

If a series of preferred stock underlying the depositary shares has a liquidation preference, in the event of the voluntary or involuntary liquidation, dissolution or winding up of State Street, holders of depositary shares will be entitled to receive the fraction of the liquidation preference accorded each share of the applicable series of preferred stock, as set forth in the applicable prospectus supplement.

Withdrawal of Stock

Unless the related depositary shares have been previously called for redemption, upon surrender of the depositary receipts at the office of the depositary, the holder of the depositary shares will be entitled to delivery, at the office of the depositary to or upon his or her order, of the number of whole shares of the preferred stock and any money or other property represented by the depositary shares. If the depositary receipts delivered by the

-27-

holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred stock to be withdrawn, the depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. In no event will the depositary deliver fractional shares of preferred stock upon surrender of depositary receipts. Holders of preferred stock thus withdrawn may not thereafter deposit those shares under the deposit agreement or receive depositary receipts evidencing depositary shares therefor.

Redemption of Depositary Shares

Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing shares of the preferred stock so redeemed, so long as we have paid in full to the depositary the redemption price of the preferred stock to be redeemed plus an amount equal to any accumulated and unpaid dividends on the preferred stock to the date fixed for redemption. The redemption price per depositary share will be equal to the redemption price and any other amounts per share payable on the preferred stock multiplied by the fraction of a share of preferred stock represented by one depositary share. If less than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata or by any other equitable method as may be determined by the depositary.

After the date fixed for redemption, depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of depositary shares will cease, except the right to receive the monies payable upon redemption and any money or other property to which the holders of the depositary shares were entitled upon redemption upon surrender to the depositary of the depositary receipts evidencing the depositary shares.

Voting the Preferred Stock

Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in the notice of meeting to the record holders of the depositary receipts relating to that preferred stock. The record date for the depositary receipts relating to the preferred stock will be the same date as the record date for the preferred stock. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the number of shares of preferred stock represented by that holder’s depositary shares. The depositary will endeavor, insofar as practicable, to vote the number of shares of preferred stock represented by the depositary shares in accordance with those instructions, and we will agree to take all action that may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will not vote any shares of preferred stock except to the extent it receives specific instructions from the holders of depositary shares representing that number of shares of preferred stock.

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of the preferred stock and any redemption of the preferred stock. Holders of depositary receipts will pay transfer, income and other taxes and governmental charges and such other charges (including those in connection with the receipt and distribution of dividends, the sale or exercise of rights, the withdrawal of the preferred stock and the transferring, splitting or grouping of depositary receipts) as are expressly provided in the deposit agreement to be for their accounts. If these charges have not been paid by the holders of depositary receipts, the depositary may refuse to transfer depositary shares, withhold dividends and distributions and sell the depositary shares evidenced by the depositary receipt.

Amendment and Termination of the Deposit Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may be amended by agreement between us and the depositary. However, any amendment that materially and

-28-

adversely alters the rights of the holders of depositary shares, other than fee changes, will not be effective unless the amendment has been approved by the holders of at least a majority of the outstanding depositary shares. The deposit agreement may be terminated by the depositary or us only if:

Resignation and Removal of Depositary

The depositary may resign at any time by delivering to us notice of its election to do so, and we may remove the depositary at any time. Any resignation or removal of the depositary will take effect upon our appointment of a successor depositary and its acceptance of such appointment. The successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having the requisite combined capital and surplus as set forth in the applicable agreement.

Notices

The depositary will forward to holders of depositary receipts all notices, reports and other communications, including proxy solicitation materials received from us, that are delivered to the depositary and that we are required to furnish to the holders of the preferred stock. In addition, the depositary will make available for inspection by holders of depositary receipts at the principal office of the depositary, and at such other places as it may from time to time deem advisable, any reports and communications we deliver to the depositary as the holder of preferred stock.

Limitation of Liability

Neither we nor the depositary will be liable if either of us is prevented or delayed by law or any circumstance beyond its control in performing its obligations. Our obligations and those of the depositary will be limited to performance in good faith of our and their duties thereunder. We and the depositary will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. We and the depositary may rely upon written advice of counsel or accountants, on information provided by persons presenting preferred stock for deposit, holders of depositary receipts or other persons believed to be competent to give such information and on documents believed to be genuine and to have been signed or presented by the proper party or parties.

DESCRIPTION OF COMMON STOCK

General

We have 750,000,000 shares of authorized common stock, $1.00 par value per share, of which 370,836,680 shares were outstanding as of October 31, 2017. For purposes of this section entitled “Description of Common Stock,” references to “State Street,” “we,” “our,” “ours” and “us” relate only to State Street Corporation and not its subsidiaries.

Holders of our common stock are entitled to receive dividends if, as and when declared by our board of directors out of any funds legally available for dividends. Holders of our common stock are also entitled, upon our liquidation, and after claims of creditors and the preferences of the series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock and series G preferred stock and any other class or series of preferred stock outstanding at the time of liquidation, to receive pro rata our net assets. We pay dividends on our common stock only if we have paid or provided for all dividends on our outstanding classes and series of preferred stock, for the then current period and, in the case of any cumulative preferred stock, all prior periods. Our ability to declare and pay dividends on our common stock is subject to certain restrictions. See “Business—Supervision and Regulation—Capital Planning, Stress Tests and Dividends” in our most recently filed Annual Report on Form 10-K. We generally are not permitted to purchase shares of our common stock unless full dividends are paid (or declared, with funds set aside for payment) on all outstanding shares of preferred stock.

Our series C preferred stock, series D preferred stock, series E preferred stock, series F preferred stock and series G preferred stock have, and any other series of preferred stock upon issuance will have, preference over our common stock with respect to the payment of dividends and the distribution of assets in the event of our liquidation, winding up or dissolution. Our preferred stock also has such other preferences as may be fixed by our board of directors.

Holders of our common stock are entitled to one vote for each share that they hold and are vested with all of the voting power except as our board of directors has provided, or may provide in the future, with respect to preferred stock or any other class or series of preferred stock that the board of directors may hereafter authorize. See “Description of Preferred Stock.” Shares of our common stock are not redeemable, and have no subscription, conversion or preemptive rights.

Our common stock is listed on the New York Stock Exchange under the ticker symbol “STT”. Outstanding shares of our common stock are validly issued, fully paid and non-assessable. Holders of our common stock are not, and will not be, subject to any liability as stockholders.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is American Stock Transfer and Trust Company.

Restrictions on Ownership

The BHC Act requires any “bank holding company,” as defined in the BHC Act, to obtain the approval of the Federal Reserve prior to the acquisition of 5% or more of our common stock. Any person, other than a bank holding company, is required to obtain prior approval of the Federal Reserve to acquire 10% or more of our common stock under the Change in Bank Control Act. Any holder of 25% or more of our common stock, or that otherwise exercises a “controlling influence” over us, is subject to regulation as a bank holding company under the BHC Act. Chapter 167A of the General Laws of Massachusetts requires any “bank holding company,” as defined in Chapter 167A, to obtain prior approval of the board of bank incorporation before (i) acquiring 5% or more of our common stock, (ii) acquiring all or substantially all of our assets or (iii) merging or consolidating with us.

We may issue purchase contracts, including contracts obligating holders to purchase from or sell to us, and obligating us to sell to or purchase from the holders, a specified number of shares of our common stock, preferred stock or depositary shares at a future date or dates, which we refer to in this prospectus as purchase contracts. The price per share of common stock, preferred stock or depositary shares and the number of shares of each may be fixed at the time the purchase contracts are issued or may be determined by reference to a specific formula set forth in the purchase contracts. The purchase contracts may be issued separately or as part of units consisting of one or more purchase contracts and beneficial interests in:

The purchase contracts may require us to make periodic payments to the holders of the units or vice versa, and these payments may be unsecured or prefunded on some basis. The purchase contracts may require holders to secure their obligations under those contracts in a specified manner, including without limitation by pledging their interest in another purchase contract. For purposes of this section entitled “Description of Purchase Contracts and Units,” references to “State Street,” “we,” “our,” “ours” and “us” relate only to State Street Corporation and not its subsidiaries.

The applicable prospectus supplement will describe the terms of the purchase contracts and units, including, if applicable, collateral or depositary arrangements.

DESCRIPTION OF WARRANTS

We may issue warrants to purchase debt securities, preferred stock, depositary shares or common stock. We may offer warrants separately or together with one or more additional warrants, debt securities, preferred stock, depositary shares or common stock, or any combination of those securities in the form of units, as described in the applicable prospectus supplement. If we issue warrants as part of a unit, the accompanying prospectus supplement will specify whether those warrants may be separated from the other securities in the unit prior to the expiration date of the warrants. For purposes of this section entitled “Description of Warrants,” references to “State Street,” “we,” “our,” “ours” and “us” relate only to State Street Corporation and not its subsidiaries.

The applicable prospectus supplement will also describe the following terms of any warrants:

FORMS OF SECURITIES

Each debt security, depositary share, purchase contract, unit and warrant will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities issued in book-entry form representing the entire issuance of securities. Unless otherwise specified in the applicable prospectus supplement, certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, depositary shares, purchase contracts, units or warrants represented by these global securities. Those who own beneficial interests in a global security will do so through participants in the depositary’s securities clearing system, and the rights of these indirect owners will be governed solely by the applicable procedures of the depositary and its participants, as we explain more fully below.

Global Securities

We may issue the debt securities, depositary shares, purchase contracts, units and warrants in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

Any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, deposit agreement, purchase contract, unit agreement or warrant agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, deposit agreement, purchase contract, unit agreement or warrant agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the

-33-

participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, deposit agreement, purchase contract, unit agreement or warrant agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, deposit agreement, purchase contract, unit agreement or warrant agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal or premium, if any, and interest payments on debt securities, and any payments to holders with respect to depositary shares, warrants, purchase contracts or units, represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of State Street, the trustees, any warrant agent, unit agent or any other agent of State Street, agent of the trustee or agent of such warrant agent or unit agent will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders of that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based on directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

PLAN OF DISTRIBUTION

We may sell securities:

In addition, we may issue the securities as a dividend or distribution or in a subscription rights offering to our existing security holders. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

We may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act and describe any commissions that we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis.

The distribution of the securities may be effected from time to time in one or more transactions:

Each prospectus supplement will describe the method of distribution of the securities and any applicable restrictions.

The prospectus supplement with respect to the securities of a particular series will describe the terms of the offering of the securities, including the following:

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

-35-

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

Remarketing firms, agents, underwriters and dealers may be entitled under agreements which they may enter into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

If so indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

Certain agents, underwriters and dealers and their associates and affiliates may be customers of, have borrowing relationships with, engage in other transactions with, and/or perform services, including investment banking services, for, us or one or more of our respective affiliates in the ordinary course of business.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

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 any such trade expressly agree otherwise or the securities are sold by us to an underwriter in a firm commitment underwritten offering. The applicable prospectus supplement may provide that the original issue date for your securities may be more than two scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the second business day before the original issue date for your securities, you will be required, by virtue of the fact

-36-

that your securities initially are expected to settle in more than two scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

The securities may be new issues of securities and may have no established trading market. The securities may or may not be listed on a national securities exchange. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

LEGAL MATTERS

Unless the applicable prospectus supplement indicates otherwise, the validity of the securities in respect of which this prospectus is being delivered will be passed upon by Wilmer Cutler Pickering Hale and Dorr LLP.

EXPERTS

The consolidated financial statements of State Street Corporation appearing in State Street Corporation’s Annual Report (Form 10-K/A) for the year ended December 31, 2016, and the effectiveness of State Street Corporation’s internal control over financial reporting as of December 31, 2016, have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

With respect to the unaudited condensed consolidated interim financial information of State Street Corporation for the three-month periods ended March 31, 2017 and March 31, 2016, for the three and six-month periods ended June 30, 2017 and June 30, 2016, and for the three and nine-month periods ended September 30, 2017 and September 30, 2016, incorporated by reference herein, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated May 4, 2017, August 4, 2017 and November 1, 2017 included in State Street Corporation’s Quarterly Report on Form 10-Q for the quarters ended March 31, 2017, June 30, 2017 and September 30, 2017, respectively, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act of 1933 (the “Act”) for their report on the unaudited interim financial information because that report is not a “report” or a “part” of the Registration Statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Act.
