Interest on the floating rate notes is payable quarterly in arrears on             ,            ,             and             of each year, commencing on                , 2016. Interest on the fixed rate notes is payable semi-annually in arrears on              and             of each year, commencing on                , 2016. State Street may not redeem the notes prior to their maturity. There is no sinking fund for the notes. The notes are unsecured and will rank equally with all other existing and future senior unsecured indebtedness of State Street.

RISK FACTORS

An investment in the notes 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 19, 2016, before deciding whether this investment is suited to your particular circumstances.

Risks Relating to the Notes

There are limited covenants in the indenture.

Neither we nor any of our subsidiaries are restricted from incurring additional indebtedness or other liabilities, including additional senior indebtedness, under the indenture governing the terms of the notes. If we incur additional indebtedness or liabilities, our ability to pay our obligations on the notes could be adversely affected. We expect that we will from time to time incur additional indebtedness and other liabilities. In addition, we are not restricted under the indenture from paying dividends or issuing or repurchasing our securities.

In addition, there are no financial covenants in the indenture. You are not protected under the indenture in the event of a highly leveraged transaction, reorganization, default under our existing indebtedness, restructuring, merger or similar transaction that may adversely affect you, except to the extent described under “Description of Debt Securities—Consolidation, Merger and Sale of Assets” included in the accompanying prospectus.

The notes will not be guaranteed by the FDIC, any other governmental agency or any of our subsidiaries. The notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries, which means that creditors of our subsidiaries generally will be paid from those subsidiaries’ assets before holders of the notes would have any claims to those assets.

The notes are not bank deposits and are not insured by the FDIC or any other governmental agency, nor are they obligations of, or guaranteed by, a bank. The notes will be obligations of State Street Corporation only and will not be guaranteed by any of our subsidiaries, including State Street Bank, which is our principal banking subsidiary. The notes will be structurally subordinated to all indebtedness and other liabilities of our subsidiaries (including liabilities to trade creditors), which means that creditors of our subsidiaries generally will be paid from those subsidiaries’ assets before holders of the notes would have any claims to those assets.

We and our subsidiaries have significant regulatory capital, leverage, liquidity and debt obligations; payments on the notes will depend on receipt of dividends and distributions from our subsidiaries.

We are a holding company and we conduct substantially all of our operations through subsidiaries, including State Street Bank, which is our principal banking subsidiary. We are also permitted, subject to certain restrictions under our existing indebtedness, to obtain additional long-term debt and working capital lines of credit to meet future financing needs. This would have the effect of increasing our total leverage. Furthermore, the indenture relating to the notes does not prohibit us or our subsidiaries from incurring additional secured or unsecured indebtedness. As of March 31, 2016, on a consolidated basis, our outstanding long-term indebtedness totaled approximately $10.00 billion (including approximately $7.08 billion of long-term senior indebtedness), and after giving effect to the issuance of the notes, would have totaled approximately $            billion.

We depend on dividends, distributions and other payments from our subsidiaries to fund payments on the notes. Further, the majority of our investments are held by our regulated subsidiaries. Our subsidiaries may be limited in their ability to make dividend payments or advance funds to us in the future because of the need to support their own capital levels. Federal banking laws regulate the amount of dividends that may be paid by State Street Bank, our principal banking subsidiary, without prior approval. In addition, the Dodd-Frank Act requires federal banking agencies to establish more stringent risk-based capital guidelines and leverage limits applicable

S-10

Table of Contents

to banks and bank holding companies, and especially those institutions, such as State Street Bank, with consolidated assets equal to or greater than $50 billion.

In July 2013, the Federal Reserve, the FDIC and the Office of the Comptroller of the Currency jointly approved the Basel III Final Rule. The Basel III Final Rule was published in the Federal Register by the Federal Reserve in October 2013. Among other things, the Basel III Final Rule (1) raises the minimum tier 1 risk-based capital ratio requirement applicable to State Street and State Street Bank, (2) adds a minimum common equity tier 1 capital ratio requirement applicable to State Street and State Street Bank, (3) adds a minimum supplementary tier 1 leverage ratio for advanced approaches banking organizations, such as State Street and State Street Bank, and (4) implements a capital conservation buffer and, for advanced approaches banking organizations including State Street and State Street Bank, a countercyclical capital buffer.

Provisions of the Basel III Final Rule become effective under a transition timetable which began on January 1, 2014. These provisions supersede or modify corresponding elements of the Basel I and Basel II risk-based and leverage capital requirements and prompt corrective action framework. The requirement for the capital conservation buffer began to be phased in on January 1, 2016, with full implementation by January 1, 2019. As it continues to be phased in, the Basel III Final Rule will change the manner in which our regulatory capital ratios are calculated, will reduce our calculated regulatory capital and will increase the minimum regulatory capital that we will be required to maintain.

On April 8, 2014, and September 3, 2014, U.S. banking regulators issued two final rules enhancing the supplementary leverage ratio, or SLR, standards for certain bank holding companies, like State Street, and their insured depository institution subsidiaries, like State Street Bank (the “SLR Final Rules”). Under the SLR Final Rules, upon implementation on January 1, 2018, State Street Bank must maintain an SLR of at least 6% to be well-capitalized under the U.S. banking regulators’ prompt corrective action provisions. The SLR Final Rules also provide that State Street must maintain an SLR of more than 5% to avoid certain limitations on distributions and discretionary bonus payments.

On September 3, 2014, U.S. banking regulators issued a final rule to implement the Basel Committee on Banking Supervision’s, or Basel Committee, liquidity coverage ratio, or LCR, in the U.S. (the “LCR Final Rule”). The LCR is intended to promote the short-term resilience of internationally active banking organizations, like State Street, to improve the banking industry’s ability to absorb shocks arising from idiosyncratic or market stress, and to improve the measurement and management of liquidity risk. The LCR Final Rule is largely similar to the proposed rule issued by U.S. banking regulators in October 2013, and maintains many of the more stringent requirements compared to the Basel Committee’s LCR. The LCR measures an institution’s high-quality liquid assets, or HQLA, against its net cash outflows. The LCR will be phased in, as originally proposed, beginning on January 1, 2015, at 80%, with full implementation beginning on January 1, 2017.

On April 26, 2016 and May 3, 2016, U.S. banking regulators proposed a rule to implement the Basel Committee’s net stable funding ratio (“NSFR”) requirement in the United States. The NSFR requirement is designed to further promote the measurement and management of liquidity risk at certain large, internationally active banking organizations and to reduce the likelihood that disruptions to those organizations’ funding sources would compromise their liquidity positions. If adopted as proposed, State Street would be required to maintain stable sources of funding, measured based on a weighted measure of the stability of its liabilities and equity over a one-year time horizon, in an amount at least equal to its minimum need for stable funding, calculated based on the liquidity characteristics of its assets and certain off-balance sheet exposures over the same one-year time horizon. Under the proposal, the NSFR requirement would apply beginning on January 1, 2018.

We meet the criteria of a large bank holding company subject to enhanced supervision and prudential standards, commonly referred to as a “systemically important financial institution,” or SIFI, and we are one among a group of 30 institutions worldwide that have been identified by the Financial Stability Board, or FSB, and the Basel Committee as “global systemically important banks,” or G-SIBs. Our designation as a G-SIB will

S-11

Table of Contents

require us to maintain additional capital buffers, including a G-SIB surcharge, determined based on one of two methods prescribed by final rules issued by the Federal Reserve on August 14, 2015. Furthermore, on October 30, 2015, the Federal Reserve released its proposed regulations for external total loss-absorbing capacity (“TLAC”) and long-term debt requirements that, among other things, would require U.S. domiciled G-SIBs (“covered BHCs”), like State Street, to hold an external TLAC buffer of 2.5% plus its G-SIB surcharge (as determined under the first of the two methods) and any applicable countercyclical buffer. In addition, on March 4, 2016, the Federal Reserve reproposed rules that would establish single-counterparty credit limit (“SCCL”) requirements for certain U.S. bank holding companies and other companies, including heightened requirements for G-SIBs such as State Street. If adopted as proposed, State Street’s net credit exposures to unaffiliated counterparties would be limited to 25 percent or 15 percent of its tier 1 capital, depending on the counterparty. See “Risk Factors—Our business and capital-related activities, including our ability to return capital to shareholders and purchase our capital stock, may be adversely affected by our implementation of the revised regulatory capital and liquidity standards that we must meet under the Basel III final rule, the Dodd-Frank Act and other regulatory initiatives, or in the event our capital plan or post-stress capital ratios are determined to be insufficient as a result of regulatory capital stress testing” in our Annual Report on Form 10-K for the year ended December 31, 2015.

Maintaining the higher capital and liquidity levels required by the Basel III Final Rule, meeting the requirements of the SLR Final Rules and the LCR Final Rule, and complying with any future regulatory requirements, including the proposed TLAC, SCCL and NSFR requirements, may reduce our profitability and performance measures and adversely affect the ability of State Street Bank to make distributions or pay dividends to State Street. As a result, our ability to make payments on the notes when due could be adversely affected.

In addition, State Street Corporation maintains a substantial portion of its available liquidity as cash deposits or other short term placements with State Street Bank. Our single point of entry resolution strategy contemplates that, under certain circumstances, we may contribute all or some portion of such deposits or other short term placements to the capital of State Street Bank. To the extent State Street Bank were to experience financial difficulties and State Street Corporation made such a capital contribution or such deposits were otherwise unavailable to State Street Corporation, State Street Corporation may not have sufficient liquidity to pay its own creditors, including the holders of the notes.

Active trading markets for the notes may not develop.

The notes constitute new issues of securities, for which there are no existing markets. We do not intend to apply for listing of the notes on any securities exchange or for quotation of the notes on any automated dealer quotation system. We cannot provide you with any assurance regarding whether trading markets for the notes will develop, the ability of holders of the notes to sell their notes or the prices at which holders may be able to sell their notes. The underwriters have advised us that they currently intend to make markets in the notes. The underwriters, however, are not obligated to do so, and any market-making with respect to the notes may be discontinued at any time without notice. If no active trading markets develop, you may be unable to resell the notes at any price or at their fair market value.

Government regulation may affect the priority of the notes in the case of a bankruptcy or liquidation.

In the event that State Street enters into resolution proceedings, your ability to recover the full amount that would otherwise be payable on the notes in a proceeding under the U.S. Bankruptcy Code may be impaired pursuant to the FDIC’s “orderly liquidation authority” under Title II of the Dodd-Frank Act or in connection with, when finalized, the Federal Reserve’s proposed rules on TLAC and long-term debt.

Title II of the Dodd-Frank Act created a new resolution regime known as “orderly liquidation authority” to which financial companies, including bank holding companies such as State Street, can be subjected. Under the orderly liquidation authority, the FDIC may be appointed as receiver for a financial company for purposes of

S-12

Table of Contents

liquidating the entity if the Secretary of the Treasury determines that the entity is in severe financial distress and that the entity’s failure would have serious adverse effects on the U.S. financial system. Absent any such determinations, State Street as a bank holding company would remain subject to the U.S. Bankruptcy Code.

If the FDIC is appointed as receiver under the orderly liquidation authority, then provisions of the Dodd-Frank Act, rather than the U.S. Bankruptcy Code, would determine the powers of the receiver, and the rights and obligations of creditors and other parties who have dealt with the institution. There are substantial differences in the possible treatment of creditors under the orderly liquidation authority compared to that under the U.S. Bankruptcy Code, including the right of the FDIC to treat similarly situated creditors differently in some circumstances, the use of an administrative claims procedure to determine creditors’ claims (as opposed to the judicial procedure utilized in bankruptcy proceedings) and the right of the FDIC to transfer claims to a third party or “bridge” entity. In certain circumstances under the orderly liquidation authority, the FDIC could elect to pay certain claims in full, transfer certain claims to a third party or “bridge” entity and leave other claims behind in a receivership, even if these claims all rank pari passu, if the FDIC determines such actions are necessary to facilitate a smooth and orderly liquidation of the institution. In such circumstances, the various claimants may receive different recoveries with respect to their respective claims. The only statutory requirement that relates to such discrimination as between similarly situated creditors is that no creditor shall be worse off than if the institution had been liquidated under the bankruptcy code or similar insolvency law. There is no requirement that the FDIC obtain creditors’ consent to, or seek prior court review of, its actions. A receivership under the orderly liquidation authority could also lead to a large reduction or total elimination of the value of the financial company’s outstanding equity. For example, the FDIC could follow a “single point of entry” approach and transfer the assets of a financial company in receivership to a newly created “bridge” entity, the equity of which could be distributed to certain of the financial company’s creditors in satisfaction of their claims, with pre-existing equity holders receiving nothing. The orderly liquidation authority provides the FDIC with authority to cause shareholders and creditors of the financial company in receivership to bear losses before taxpayers are exposed to such losses, and amounts owed to the U.S. government would generally receive a statutory payment priority over the claims of private creditors, including senior creditors.

While the FDIC has issued regulations to implement the orderly liquidation authority, not all aspects of how the FDIC might exercise this authority are known and additional rulemakings are likely. Further, it is uncertain how the FDIC might exercise its discretion under the orderly liquidation authority in a particular case.

In addition, the Federal Reserve’s proposed TLAC and long-term debt requirements for covered BHCs, like State Street, would impose: (1) TLAC requirements (i.e., combined eligible Tier 1 regulatory capital and eligible long-term debt); (2) separate eligible long-term debt requirements; and (3) clean holding company requirements designed to make short-term unsecured debt (including deposits) and most other ineligible liabilities structurally senior to eligible long-term debt. The proposed rule would also require banking organizations subject to the Federal Reserve’s Basel III capital rules to deduct from regulatory capital any investments in unsecured debt issued by a G-SIB.

If adopted as proposed, the rule would, among other things, require State Street to hold (1) qualifying equity and long-term debt in at least equal to the greater of 21.5% of total risk-weighted assets (using the capital conservation buffer of 2.5% and an estimated G-SIB method 1 surcharge of 1%) and 9.5% of total leverage exposure, as defined by the SLR Final Rule, and (2) qualifying external long-term debt at least equal to the greater of 7.5% of risk weighted assets (using an estimated G-SIB method 2 surcharge of 1.5%) and 4.5% of total leverage exposure, as defined by the SLR Final Rule.

If adopted as proposed, the rule would not allow debt securities that permit acceleration for reasons other than the insolvency of or payment default by the covered BHC to qualify as eligible long-term debt counting towards the minimum TLAC and long-term debt requirements. The current outstanding long-term debt of State Street typically permits acceleration for reasons other than insolvency of, and payment default by, State Street, and, as a result, none of such outstanding long-term debt securities, or long-term debt securities containing such

S-13

Table of Contents

acceleration provisions issued in the future, including the notes, will qualify as eligible long-term debt under the proposed rule. The Federal Reserve requested comment on whether outstanding long-term debt should be “grandfathered” despite containing features that would be prohibited under the proposed rule, although we cannot assure you as to the nature of any such “grandfathering” that may be included in the final rule or if the final rule will include any “grandfathering”. Any steps that State Street may need to undertake to comply with the final rule, including liability management exercises or new issuances, will depend in substantial part upon any “grandfathering” or modification of the eligibility requirements provided by the final rule.

A downgrade in our credit ratings, changes in the debt markets or other developments could limit our ability to obtain future financing, increase our borrowing costs and adversely affect the trading prices and liquidity of the notes.

The trading prices for the notes will depend on many factors, including:

The condition of the financial markets and prevailing interest rates have fluctuated significantly in the past and are likely to fluctuate in the future. Such fluctuations could have an adverse effect on the prices of the notes.

In addition, we are subject to periodic review by independent credit rating agencies. An increase in the level of our outstanding indebtedness, or other events that could have an adverse impact on our financial condition or results of operations, may cause the rating agencies to downgrade, place on negative watch or change their outlook on our debt credit rating generally, and the ratings on the notes, which could adversely impact the trading prices, or the liquidity, of the notes. Any such downgrade, placement on negative watch or change in outlook could also adversely affect our cost of borrowing, limit our access to the capital markets or result in restrictive covenants in future debt agreements. The ratings on the notes may not reflect the potential impact of all risks related to structure, market, additional factors discussed above and other factors that may affect the value of the notes. A credit rating is not a recommendation to buy, sell or hold securities and may be revised, suspended or withdrawn by the rating agency at any time.

A State Street Bank bankruptcy, insolvency or reorganization event, or the appointment of a custodian, receiver or other similar official of the State Street Bank or all or substantially all of its property, will not constitute an event of default under the notes.

The terms of the notes will provide that an event of bankruptcy, insolvency or reorganization event with respect to State Street Bank, or the appointment of a custodian, receiver or other similar official of State Street Bank or all or substantially all of its property, will not constitute an event of default under the notes. As a result, if there is a bankruptcy, insolvency or reorganization event, or a receivership, with respect to State Street Bank but not State Street, and if there is not a payment default or other default under the notes, holders of the notes will not be entitled to accelerate the principal amount of their notes.

The amount of interest payable on the floating rate notes is set only once per interest period based on the three-month U.S. dollar LIBOR rate on the interest determination date, which rate may fluctuate substantially.

In the past, the level of the three-month U.S. dollar LIBOR rate has experienced significant fluctuations. You should note that historical levels, fluctuations and trends of the three-month U.S. dollar LIBOR rate are not necessarily indicative of future levels. Any historical upward or downward trend in the three-month U.S. dollar LIBOR rate is not an indication that the three-month U.S. dollar LIBOR rate is more or less likely to increase or

S-14

Table of Contents

decrease at any time during a floating rate interest period, and you should not take the historical levels of the three-month U.S. dollar LIBOR rate as an indication of its future performance. You should further note that although the actual three-month U.S. dollar LIBOR rate on an interest payment date or at other times during an interest period may be higher than the three-month U.S. dollar LIBOR rate on the applicable interest determination date, you will not benefit from the three-month U.S. dollar LIBOR rate at any time other than on the interest determination date for such interest period. As a result, changes in the three-month U.S dollar LIBOR rate may not result in a comparable change in the market value of the floating rate notes.

DESCRIPTION OF THE NOTES

Each series of notes offered by this prospectus supplement will be issued by State Street Corporation under an indenture dated as of October 31, 2014, between State Street Corporation and U.S. Bank National Association, as senior trustee (the “Indenture”). The accompanying prospectus provides a more complete description of the Indenture. The notes will be senior debt securities, as such term is used in the accompanying prospectus. The following description of the particular terms of the notes supplements and, to the extent inconsistent therewith, replaces the description of the general terms and provisions of the senior debt securities in the accompanying prospectus, to which description we refer you.

General

The floating rate notes issued in this offering initially will be limited to $            aggregate principal amount, the 2021 notes issued in this offering initially will be limited to $            aggregate principal amount and the 2026 notes issued in this offering initially will be limited to $            aggregate principal amount. The floating rate notes will mature on                 , 2021, the 2021 notes will mature on                 , 2021 and the 2026 notes will mature on                 , 2026.

We will not pay any additional amounts on the notes to compensate any beneficial owner for any United States tax withheld from payments of principal or interest on the notes. We may not redeem the notes prior to their maturity. There is no sinking fund for the notes. The notes are not convertible into, or exchangeable for, equity securities of State Street. The notes are subject to defeasance in the manner described under the heading “Description of Debt Securities—Defeasance” in the accompanying prospectus.

The notes will rank equally with all of State Street’s other existing and future senior unsecured indebtedness. As of March 31, 2016, on a consolidated basis, our outstanding long-term senior indebtedness totaled approximately $7.08 billion, and after giving effect to the issuance of the notes, would have totaled approximately $            billion.

Interest

Floating Rate Notes

Interest on the floating rate notes will accrue from and including                 , 2016. The initial interest period for the floating rating notes is the period from and including                 , 2016 to, but excluding, the next interest reset date (as defined below), and subsequent interest periods will be the periods from and including an interest reset date to, but excluding, the next interest reset date.

Interest on the floating rate notes will be payable quarterly in arrears on                 ,                 ,                 and                  of each year, commencing on                 , 2016 (each a “floating rate interest payment date”), and on the maturity date of the floating rate notes. If a floating rate interest payment date for the floating rate notes falls on a day that is not a business day and a London business day, then such date will be postponed to the next day that is both a business day and a London business day, except that, if the next such date falls in the next calendar month, then such date will be advanced to the immediately preceding day that is both a business day and a London business day. If the maturity date of the floating rate notes is not a business day and a London business day, any payment of principal and interest otherwise due on such day will be made on the next succeeding date that is a business day and a London business day, and no interest on such payment shall accrue for the period from and after such maturity date.

The interest payable on the floating rate notes on any floating rate interest payment date, subject to certain exceptions, will be paid to the person in whose name such floating rate notes are registered at the close of business on                 ,                 ,                 and                 , whether or not a London business day or a business day, next preceding the applicable floating rate interest payment date. However, interest that we pay on the maturity date of the floating rate notes will be paid to the person to whom the principal will be payable.

S-17

Table of Contents

The floating rate notes will bear interest at a per annum rate equal to the applicable LIBOR rate plus     %, reset quarterly. Interest on the floating rate notes will be computed on the basis of a 360-day year for the actual number of days elapsed. Interest will be reset on                 ,                 ,                 and                 of each year, commencing on                , 2016 (each, an “interest reset date”). If an interest reset date for the floating rate notes falls on a day that is not a business day and a London business day, then such date will be postponed to the next day that is both a business day and a London business day, except that, if the next such date falls in the next calendar month, then such date will be advanced to the immediately preceding day that is both a business day and a London business day. The LIBOR rate in effect for the initial interest period will be     %. For subsequent interest periods, LIBOR will be determined by the calculation agent on the second London business day immediately preceding the first day of such interest period (each, an “interest determination date”) in the following manner:

The calculation agent is State Street Bank unless and until such time as a successor is appointed. State Street may appoint a different institution to serve as calculation agent from time to time after the original issue date of the floating rate notes without the consent of holders of the floating rate notes and without notice. The calculation agent’s determination of any interest rate, and its calculation of the amount of interest for any interest period, will be on file at our principal offices, will be made available to any noteholder upon request and will be final and binding in the absence of manifest error.

In this subsection, we use several terms that have special meanings relevant to calculating LIBOR. We define these terms as follows:

The term “London business day” means each Monday, Tuesday, Wednesday, Thursday and Friday that is not a day on which banking institutions in London generally are authorized or obligated by law, regulation or

S-18

Table of Contents

executive order to close and, in the case of any debt security for which LIBOR is an interest rate basis, is also a day on which dealings in the applicable index currency are transacted in the London interbank market.

The term “Representative Amount” means an amount that, in the calculation agent’s judgment, is representative of a single transaction in the relevant market at the relevant time.

The term “Reuters screen” means the display on the Reuters 3000 Xtra service, or any successor or replacement service.

All percentages resulting from any calculation of the interest rate on the floating rate notes will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)), and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

The interest rate on the floating rate notes will in no event be higher than the maximum rate permitted by New York law as the same may be modified by United States law of general application.

Fixed Rate Notes

The 2021 notes will bear interest at a rate of     % per annum and the 2026 notes will bear interest at a rate of     % per annum. Interest on each series of fixed rate notes will accrue from and including                 , 2016 and will be payable semi-annually in arrears on                 and                 of each year, commencing on                 , 2016 (each a “fixed rate interest payment date”), and on the maturity date of such series. Interest on the fixed rate notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

If a fixed rate interest payment date or the maturity date for a series of fixed rate notes falls on a day that is not a business day, we will postpone the interest payment or the payment of principal and interest at maturity to the next succeeding business day, but the payments made on such dates will be treated as having been made on the date that the payment was first due and the holders of such series of fixed rate notes will not be entitled to any further interest or other payments with respect to such postponements.

The interest payable on a series of fixed rate notes on any interest payment date, subject to certain exceptions, will be paid to the person in whose name the notes of such series are registered at the close of business on                 and                 , whether or not a business day, next preceding the applicable interest payment date. However, interest that we pay on the maturity date of the fixed rate notes of such series will be paid to the person to whom the principal will be payable.

General

Interest will be payable by wire transfer in immediately available funds in U.S. dollars at the office of the paying agent or, in the event the notes are not represented by Global Notes (as defined below), at the office or agency of State Street maintained for such purpose in The City of Boston.

When we use the term “business day” in this “—Interest” section, we mean any day other than a Saturday, Sunday or other day on which banking institutions in The City of New York or The City of Boston are authorized or required by law or executive order to remain closed.

Events of Default

The following are “events of default” with respect to each series of notes:

S-19

Table of Contents

If an event of default occurs and is continuing with respect to a series of notes, other than an event of default resulting from voluntary bankruptcy, insolvency or reorganization of State Street, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding notes of such series may declare the principal amount of all notes of such series to be due and payable or deliverable immediately. The notes will automatically be accelerated upon the occurrence of an event of default resulting from voluntary bankruptcy, insolvency or reorganization of State Street.

Notwithstanding any provision to the contrary in the Indenture, 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 with respect to the notes. By purchasing these notes an investor hereby agrees, for itself and any and all successors and assigns, that the events described in clauses (5) and (6) of Section 501 of the Indenture, insofar as they relate to State Street Bank, shall not constitute an event of default with respect to either series of notes offered by this prospectus supplement.

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

Waiver and Termination of Rights With Respect to State Street Replacement Capital Covenant

In 2007, we caused the issuance of $800 million of floating rate capital securities (“Capital Securities”) of State Street Capital Trust IV, a Delaware statutory trust formed by us (the “Trust”), and issued $800 million of our floating rate junior subordinated debentures to the Trust (the “Underlying Securities” and, together with the Capital Securities, the “Securities”). In connection with these issuances, on April 30, 2007 we entered into a replacement capital covenant, which we subsequently amended on May 13, 2016 (as amended, the “Replacement Capital Covenant”). The Replacement Capital Covenant benefits persons that buy, hold or sell specified series of long-term indebtedness of our company, or our depository institution subsidiaries (the “Covered Debt”). The current Covered Debt under the Replacement Capital Covenant is our floating rate junior subordinated debentures due in 2028 (the “Debentures”), issued to State Street Capital Trust I, a Delaware statutory trust formed by us, underlying the floating rate capital securities of State Street Capital Trust.

The Replacement Capital Covenant provides that we may not repay, redeem or purchase any of the Securities, and no subsidiary of ours (including the Trust) may purchase, any of the Securities, on or before the date specified in the Replacement Capital Covenant, with certain limited exceptions, except to the extent that (i) we have obtained the prior approval of the Federal Reserve Board, if such approval is then required, and (ii) we have received proceeds, up to specified percentages of the aggregate principal amount repaid or the applicable redemption or purchase price, from the sale or issuance of qualifying securities with characteristics that are the same as, or more equity-like than, the applicable characteristics of the Securities during the 180 days prior to the date of that repayment, redemption or purchase (which period is shortened under certain specified circumstances).

In the event that we elect to redeem the securities that serve as the Covered Debt (currently the Debentures), either in full or in part and, as a result thereof, the principal amount thereof is reduced below a specified threshold, we are required to identify another series of eligible debt to serve as the Covered Debt entitled to the benefits of the Replacement Capital Covenant. The floating rate notes, the 2021 notes and the 2026 notes would each qualify as Covered Debt if we designated them as such and, therefore, if we redeem the Debentures we may designate any of the floating rate notes, the 2021 notes or the 2026 notes as the Covered Debt. If we designate

S-20

Table of Contents

any of the floating rate notes, the 2021 notes or the 2026 notes as the Covered Debt, we expect that we would thereafter terminate the Replacement Capital Covenant in accordance with the terms of the applicable series of notes as described below.

The floating rate notes, 2021 notes and 2026 notes will each provide that, in the event they are designated as the Covered Debt, each purchaser of such notes, for itself and any and all successors and assigns, waives all rights under, and irrevocably authorizes us to terminate, without further action by or payment to any holders of such notes, the Replacement Capital Covenant. This feature of the floating rate notes, 2021 notes and 2026 notes will effectively allow us to unilaterally terminate the Replacement Capital Covenant, if we so choose, in the event the floating rate notes, 2021 notes or 2026 notes are designated as the Covered Debt. This will provide us with flexibility, if and when we repay, redeem or purchase the Debentures, to redeem the Securities without issuing qualifying securities under the Replacement Capital Covenant.

By purchasing floating rate notes, 2021 notes or 2026 notes, an investor shall be deemed to have waived, for itself and any and all successors and assigns, all rights with respect to, and to have irrevocably authorized us to terminate, the Replacement Capital Covenant upon such notes becoming the Covered Debt as described above.

Further Issuances

We may from time to time, without the consent of the holders of the applicable series of notes, create and issue additional notes of such series on terms and conditions substantially identical to those of such series of notes offered by this prospectus supplement (except for the issue date, public offering price and amount and date of the first payment of interest thereon), which additional notes shall increase the aggregate principal amount of, and shall be consolidated and form a single series with, the notes of such series.

Modification and Waiver

The Indenture may, with certain exceptions as provided therein, be modified and amended with respect to a series of notes by us and the trustee with the consent of holders of at least a majority in aggregate principal amount of the outstanding notes of such series. In addition, the holders of at least a majority in aggregate principal amount of the outstanding notes of a series may waive certain covenants and past defaults under the Indenture relating to such series, except as described under the heading “Description of Debt Securities—Events of Default” in the accompanying prospectus.

Delivery and Form

The notes will be represented by permanent global certificates (each a “Global Note” and collectively, the “Global Notes”) deposited with, or on behalf of, The Depository Trust Company (“DTC”) and registered in the name of Cede & Co. (DTC’s partnership nominee). Each series of notes will be available for purchase in denominations of $2,000 and integral multiples of $1,000 in excess thereof in book-entry form only. Unless and until certificated notes are issued under the limited circumstances described in the accompanying prospectus, no beneficial owner of a note shall be entitled to receive a definitive certificate representing the notes. So long as DTC or any successor depositary (collectively, the “Depositary”) or its nominee is the registered owner of the Global Notes, the Depositary, or such nominee, as the case may be, will be considered to be the sole owner or holder of the notes for all purposes of the Indenture. Beneficial interests in the Global Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the Global Notes through DTC either directly if they are participants in DTC or indirectly through organizations that are participants in DTC.

S-21

Table of Contents

Clearance and Settlement Procedures

Initial settlement of the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds.

Trustee

U.S. Bank National Association will act as trustee for the notes, which will be issued under the Indenture. The Indenture is described in the accompanying prospectus. You should read the accompanying prospectus for a general discussion of the terms and provisions of the Indenture.

MATERIAL U.S. FEDERAL TAX CONSEQUENCES

The following is a summary of material U.S. federal income and estate tax considerations related to the purchase, ownership and disposition of the notes. This summary is based upon provisions of the Internal Revenue Code of 1986, as amended ( the “Code”), U.S. Treasury Regulations, administrative rulings and judicial decisions in effect as of the date of this prospectus supplement, any of which may subsequently be changed, possibly retroactively, or interpreted differently by the Internal Revenue Service (the “IRS”), so as to result in U.S. federal income and estate tax consequences different from those discussed below. Except where noted, this summary deals only with notes held as capital assets (generally for investment purposes) by a beneficial owner who purchases notes on original issuance at the initial offering price at which a substantial amount of the notes are sold for cash to persons other than bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers, which we refer to as the “issue price.” This summary does not address all aspects of U.S. federal income and estate taxes related to the purchase, ownership and disposition of the notes and does not address all tax consequences that may be relevant to holders in light of their personal circumstances or particular situations, such as:

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds notes, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. A beneficial owner that is a partnership and partners in such a partnership should consult their tax advisors.

This summary of material U.S. federal income and estate tax considerations is for general information only and is not tax advice for any particular investor. This summary does not address the tax considerations arising under the laws of any foreign, state, or local jurisdiction. If you are considering the purchase of notes, you should consult your tax advisors concerning the U.S. federal income and estate tax consequences to you in light of your own specific situation, as well as consequences arising under the laws of any other taxing jurisdiction.

In this discussion, we use the term “U.S. holder” to refer to a beneficial owner of notes, that is, for U.S. federal income tax purposes:

S-23

Table of Contents

We use the term “non-U.S. holder” to describe a beneficial owner (other than a partnership or other pass- through entity) of notes that is not a U.S. holder. Non-U.S. holders should consult their tax advisors to determine the U.S. federal, state, local and other tax consequences that may be relevant to them.

Consequences to U.S. Holders

Payments of Interest

It is anticipated, and this discussion assumes, that the issue price of each series of notes will be equal to the stated principal amount or if the issue price is less than the stated principal amount, the difference will be a de minimis amount (as set forth in the applicable U.S. Treasury Regulations). In such case, interest on a note generally will be taxable to a U.S. holder as ordinary income at the time it is received or accrued in accordance with the U.S. holder’s usual method of accounting for tax purposes. If, however, the issue price of a series of notes is less than the stated principal amount and the difference is more than a de minimis amount (as set forth in the applicable U.S. Treasury Regulations), a U.S. holder will be required to include the difference in income as original issue discount as it accrues in accordance with a constant yield method.

Sale, Redemption or Other Taxable Disposition of Notes

A U.S. holder generally will recognize gain or loss upon the sale, redemption or other taxable disposition of a note equal to the difference between the amount realized (except to the extent any amount realized is attributable to accrued but unpaid interest, which will be taxable as ordinary interest income to the extent not previously included in income) and such U.S. holder’s adjusted tax basis in the note. A U.S. holder’s adjusted tax basis in a note will generally be equal to the amount that such U.S. holder paid for the note decreased by the amount of any principal payments received by the U.S. holder with respect to such note. Any gain or loss recognized on a taxable disposition of the note will be capital gain or loss. If, at the time of the sale, redemption or other taxable disposition of the note, a U.S. holder is treated as holding the note for more than one year, such capital gain or loss will be a long-term capital gain or loss. Otherwise, such capital gain or loss will be a short- term capital gain or loss. In the case of certain non-corporate U.S. holders (including individuals), long-term capital gain generally is subject to U.S. federal income tax at a lower rate than short-term capital gain, which is taxed at ordinary income rates. A U.S. holder’s ability to deduct capital losses may be limited.

Assumption of our Obligations under the Notes

Under certain circumstances described in the accompanying prospectus under the heading “Description of Debt Securities—Consolidation, Merger and Sale of Assets,” our obligations under the notes and the Indenture may be assumed by another person. An assumption by another person of our obligations under the notes and the Indenture might be deemed for U.S. federal income tax purposes to be an exchange by a holder of the notes for new notes, resulting in recognition of gain or loss for such purposes and possibly other adverse tax consequences to the holder. In certain circumstances, such an assumption might not be deemed an exchange for U.S. federal income tax purposes. Holders should consult their own tax advisors regarding the tax consequences of such an assumption.

Information Reporting and Backup Withholding

Information reporting requirements generally will apply to payments of interest on the notes and to the proceeds of a sale of a note paid to a U.S. holder unless the U.S. holder is an exempt recipient (such as a corporation). Backup withholding will apply to those payments if the U.S. holder fails to provide its correct taxpayer identification number, or certification of exempt status, generally by providing an IRS Form W-9 or an

S-24

Table of Contents

approved substitute, or if the U.S. holder is notified by the IRS that the U.S. holder has failed to report in full payments of interest and dividend income. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a U.S. holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

Consequences to Non-U.S. Holders

Payments of Interest

In general, payments of interest on the notes to, or on behalf of, a non-U.S. holder will be considered “portfolio interest” and, subject to the discussions below of income effectively connected with a U.S. trade or business, backup withholding, and FATCA, will not be subject to U.S. federal income or withholding tax, provided that:

If a non-U.S. holder cannot satisfy the requirements described above, payments of interest generally will be subject to the 30% U.S. federal withholding tax, unless the non-U.S. holder provides us with a properly executed (i) IRS Form W-8BEN or W-8BEN-E (or other applicable form) claiming an exemption from or reduction in withholding under an applicable income tax treaty or (ii) IRS Form W-8ECI (or other applicable form) stating that interest paid on the notes is not subject to withholding tax because it is effectively connected with the non- U.S. holder’s conduct of a trade or business in the United States and includable in the non-U.S. holder’s gross income.

If a non-U.S. holder is engaged in a trade or business in the United States and interest on the notes is effectively connected with the conduct of that trade or business and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base, then, although the non-U.S. holder will be exempt from the 30% withholding tax (provided the certification requirements discussed above are satisfied), the non-U.S. holder will be subject to U.S. federal income tax on that interest on a net income basis at regular graduated U.S. federal income tax rates, generally in the same manner as if the non-U.S. holder were a U.S. holder. In addition, if a non-U.S. holder is a foreign corporation, it may be subject to a branch profits tax equal to 30% (or lesser rate under an applicable income tax treaty) of its effectively connected earnings and profits for the taxable year, subject to certain adjustments.

S-25

Table of Contents

Sale, Redemption, or Other Taxable Disposition of Notes

Subject to the discussion below regarding FATCA, gain realized by a non-U.S. holder on the sale, redemption or other taxable disposition of a note will not be subject to U.S. income tax unless:

If a non-U.S. holder is described in the first bullet point above, it will be subject to tax on the net gain derived from the sale, redemption, or other taxable disposition of the notes at regular graduated U.S. federal income tax rates, generally in the same manner as if the non-U.S. holder were a U.S. holder. In addition, if a non- U.S. holder is a foreign corporation, it may be subject to the branch profits tax equal to 30% (or lesser rate under an applicable income tax treaty) of its effectively connected earnings and profits for the taxable year, subject to certain adjustments. If a non-U.S. holder is an individual described in the second bullet point above, such holder will be subject to a flat 30% tax (unless an applicable income tax treaty provides otherwise) on the gain derived from the sale, redemption, or other taxable disposition, which may be offset by certain U.S. source capital losses, even though such holder is not considered a resident of the United States.

Information Reporting and Backup Withholding

Generally, we must report annually to the IRS and to non-U.S. holders the amount of interest paid to non- U.S. holders and the amount of tax, if any, withheld with respect to those payments. Copies of the information returns reporting such interest payments and withholding may also be made available to the tax authorities in the country in which a non-U.S. holder resides under the provisions of an applicable income tax treaty.

In general, a non-U.S. holder will not be subject to backup withholding with respect to payments of interest that we make, provided the certification described above in the last bullet point under “Consequences to Non- U.S. Holders—Payments of Interest” has been received and we do not have actual knowledge or reason to know that the holder is a U.S. person, as defined under the Code, who is not an exempt recipient. In addition, a non- U.S. holder will be subject to information reporting and, depending on the circumstances, backup withholding with respect to payments of the proceeds of the sale of a note within the United States or conducted through certain U.S.-related financial intermediaries, unless the certification described above has been received, and we do not have actual knowledge or reason to know that a holder is a U.S. person, as defined under the Code, who is not an exempt recipient, or the non-U.S. holder otherwise establishes an exemption. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against a non-U.S. holder’s U.S. federal income tax liability provided the required information is furnished timely to the IRS. The backup withholding and information reporting rules are complex, and non-U.S. holders are urged to consult their own tax advisors regarding application of these rules to their particular circumstances.

FATCA

Provisions of the Code commonly referred to as the Foreign Account Tax Compliance Act, or FATCA, generally impose a 30% withholding tax on payments of interest on the notes and, after December 31, 2018, gross proceeds from the sale or other disposition of the notes (including settlement of the notes at maturity) 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, or (iii) the foreign entity is otherwise exempt from FATCA. If withholding under FATCA is required on any payment related to the notes, investors not otherwise subject to withholding (or that otherwise would be entitled to a reduced rate of

S-26

Table of Contents

withholding) on such payment may be required to seek a refund or credit from the IRS to obtain the benefit of such exemption (or reduction). Prospective investors are encouraged to consult their own tax advisors regarding the possible implications of FATCA on their investment in the notes.

U.S. Federal Estate Taxes

A note beneficially owned by an individual who is not a citizen or resident of the U.S. (as specially defined for U.S. federal estate tax purposes) at the time of his or her death generally will not be subject to U.S. federal estate tax as a result of the individual’s death, provided that:

UNDERWRITING

Under the terms and subject to the conditions contained in an underwriting agreement dated                     , 2016, we have agreed to sell to the underwriters named below, for whom Merrill Lynch, Pierce, Fenner & Smith Incorporated, Goldman, Sachs & Co., Deutsche Bank Securities Inc., J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC are acting as representatives, the following respective principal amounts of the notes:

The underwriting agreement provides that, subject to certain conditions, the underwriters are obligated to purchase all of the notes in the offering if they purchase any notes. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering may be terminated. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The underwriters propose to offer the notes initially at the public offering prices on the cover page of this prospectus supplement and to selling group members at those prices less selling concessions of up to    % of the principal amount per floating rate note, up to    % of the principal amount per 2021 note and up to    % of the principal amount per 2026 note. Any underwriter may allow, and any such dealer may reallow, concessions of up to    % of the principal amount per floating rate note, up to    % of the principal amount per 2021 note and up to    % of the principal amount per 2026 note to certain other dealers. After the initial public offering of the notes, the underwriters may change the public offering prices and concessions and discounts to dealers.

The following table summarizes the compensation we will pay:

We estimate that we will pay expenses of approximately $        .

The notes are new issues of securities with no established trading markets. In addition, we have not applied and do not intend to list the notes on any securities exchange or to have the notes quoted on a quotation system. One or more of the underwriters intends to make secondary markets for the notes. However, they are not obligated to do so and may discontinue making secondary markets for the notes at any time without notice. No assurance can be given as to how liquid the trading markets for the notes will be.

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

S-28

Table of Contents

Some of the underwriters and their affiliates 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 have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their 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 notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

In connection with the offering, the underwriters may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934 (the “Exchange Act”).

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result, the price of the notes may be higher than the price that might otherwise exist in the open market. These transactions, if commenced, may be discontinued at any time.

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

S-29

Table of Contents

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 for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 (or, in the case of securities issued or guaranteed by the government of a non Canadian jurisdiction, section 3A.4) of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

European Economic Area

In relation to each Member State of the European Economic Area no offer of notes which are the subject of the offering has been or will be made to the public in that Member State other than under the following exemptions under the Prospectus Directive:

A. to any legal entity which is a qualified investor as defined in the Prospectus Directive;

B. to fewer than 150 natural or legal persons (other than qualified investors as defined in the Prospectus Directive), subject to obtaining the prior consent of the representatives for any such offer; or

C. in any other circumstances falling within Article 3(2) of the Prospectus Directive,

provided that no such offer of notes shall require us or the representatives to publish a prospectus pursuant to Article 3 of the Prospectus Directive or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.

This prospectus has been prepared on the basis that any offer of notes in any Member State will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of notes. Accordingly any person making or intending to make an offer in that Member State of notes which are the subject of the offering contemplated in this prospectus may only do so in circumstances in which no obligation arises for us or any of the underwriters to publish a prospectus pursuant to Article 3 of the Prospectus Directive in relation to such offer. Neither State Street nor the underwriters have authorized, nor do they authorize, the making of any offer of notes in circumstances in which an obligation arises for us or the underwriters to publish a prospectus for such offer.

For the purpose of the above provisions, the expression an “offer of notes to the public” in relation to any notes in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe the notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression “Prospectus Directive” means Directive 2003/71/EC (as amended) and includes any relevant implementing measure in each Member State.

Hong Kong

The notes may not be offered or sold by means of any document other than (i) in circumstances which do not constitute an offer to the public within the meaning of the Companies Ordinance (Cap.32, Laws of Hong Kong), or (ii) to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap.571, Laws of Hong Kong) and any rules made thereunder, or (iii) in other circumstances which do not result in the document being a “prospectus” within the meaning of the Companies Ordinance (Cap.32, Laws of Hong Kong), and no advertisement, invitation or document relating to the notes may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the

LEGAL MATTERS

Certain legal matters in connection with the offering of the notes will be passed upon for us by Wilmer Cutler Pickering Hale and Dorr LLP. The underwriters have 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, 2015, and the effectiveness of State Street Corporation’s internal control over financial reporting as of December 31, 2015, 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, 2016 and 2015 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 report dated May 6, 2016, included in State Street Corporation’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2016, 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 for their report on the unaudited interim financial information because their 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.

FORWARD-LOOKING STATEMENTS

This prospectus and the documents incorporated by reference herein, and other public statements we may make, 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, market growth, acquisitions, joint ventures and divestitures, new technologies, services and opportunities, and expected outcomes of legal proceedings, as well as regarding 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,” “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, 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:

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 date subsequent to the time this prospectus is filed with the SEC. Unless specifically required by law, we undertake no obligation to revise our forward-looking statements after the time they are made. The factors discussed above 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 or financial condition.

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

Our senior debt securities will be issued under an indenture dated as of October 31, 2014, as amended or supplemented from time to time, between us and U.S. Bank National Association, as senior trustee, which we refer to as the senior indenture. The subordinated debt securities will be issued under an indenture dated as of October 31, 2014, as amended or supplemented from time to time, between us and Wells Fargo Bank, National Association, as subordinated trustee, which we refer to as the subordinated indenture. Each indenture is incorporated by reference as an exhibit to the registration statement that contains this prospectus. For purposes of this section, 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, all provisions 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 17. 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:

10

Table of Contents

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.

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.

11

Table of Contents

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

The following are “events of default” under the senior indenture and “defaults” under the subordinated indenture with respect to any series of debt securities:

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 or State Street Bank, the senior trustee or the holders of at least 25% in aggregate principal amount or issue price 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 or State Street Bank. At any time after the senior trustee or the holders have accelerated any series of debt securities, but before the senior trustee has obtained a judgment or decree for payment of money due or delivery of the maturity consideration, the holders of a majority in aggregate principal amount or issue price 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.

In the case of a default in the payment of interest or principal, or premium, if any, 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,

12

Table of Contents

the whole amount then due and payable on such senior 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 with respect to the senior debt securities, the trustee may in its discretion proceed to protect and enforce its rights and the rights of the holders of the senior 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 senior indenture, or to enforce any other proper remedy.

Under the subordinated indenture, an event of default is limited to certain events involving the bankruptcy, insolvency or reorganization of State Street. The subordinated 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. In the case of a default (which, for clarity is different than 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 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, including any sinking fund payment or analogous obligations, 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. In the case of any default with respect to the subordinated debt securities, the 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.

The holders of a majority in principal amount or aggregate issue price of the outstanding debt securities of any series may waive an event of default with respect to that series, except a default:

The holders of a majority in principal amount or issue price 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 debt security of any series will have the right to institute a proceeding with respect to the indenture or for any remedy thereunder, unless:

13

Table of Contents

However, any holder of a 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 trustees annually a statement as to the performance of our obligations under the indentures and as to any default in such performance.

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 or issue price 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:

14

Table of Contents

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:

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.

Such debt securities may be issued in bearer form and will be described in the applicable prospectus supplement. In connection with any offering outside the United States, we will designate paying agents, registrars or other agents with respect to the debt securities, as specified in the applicable prospectus supplement.

Offerings of debt securities to be issued or sold outside the United States may be subject to certain selling restrictions that will be described in the applicable prospectus supplement. These debt securities may be listed on one or more foreign stock exchanges as described in the applicable prospectus supplement. Special United States tax and other considerations, if any, applicable to an offering outside the United States will be described in the applicable prospectus supplement.

Limitation Upon Disposition of Voting Stock of State Street Bank

The senior indenture prohibits us and any of our 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 in each case, to us or to one or more of our wholly-owned U.S. subsidiaries, referred to as our intermediate subsidiaries.

This restriction does not apply to dispositions made by us or any subsidiary:

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.”

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

16

Table of Contents

respect to covenants relating to the debt securities of such series. Thereafter, any failure to comply with those obligations will not constitute a default or event of default 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 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

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.

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.

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:

17

Table of Contents

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) our 3.10% Senior Subordinated Notes Due 2023; 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 which will be filed with the SEC in connection with the offering of a particular series of preferred stock.

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, 5,001 shares have been designated as Non-Cumulative Perpetual Preferred Stock, Series A, or the series A preferred stock, 20,000 shares have been designated as Fixed Rate Cumulative Preferred Stock, Series B, or the series B preferred stock, 5,000 shares have been designated as Non-Cumulative Perpetual Preferred Stock, Series C, or the series C preferred stock and 7,500 shares have been designated as Fixed-to-Floating Rate Non-Cumulative Perpetual Preferred Stock, Series D, or the series D 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 and 7,500 shares of our series D preferred stock were outstanding as of September 30, 2014. We redeemed 20,000 shares of our series B preferred stock in 2009 and 5,001 shares of our series A preferred stock in 2012, and therefore none of our preferred stock other than the series C preferred stock and series D preferred stock is outstanding as of September 30, 2014.

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 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.

20

Table of Contents

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

Our series C preferred stock and series D 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. 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 or our series D preferred stock, the series C preferred stock and series D 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 and the series D 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 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.

21

Table of Contents

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, 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 subject to policies established by the Federal Reserve Board.

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 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 the preferred stock may be redeemable, in whole or in part, at our option with prior Federal Reserve Board approval. In addition, a series of preferred stock may be subject to mandatory redemption pursuant to a sinking fund or otherwise. The 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.

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.

22

Table of Contents

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 Board.

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 and series D preferred stock, or any preferred stock designated as ranking equally with the series C preferred stock and series D 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 and series D 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 and series D 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 and series D 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 the series C preferred stock and series D 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 and series D 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 Board, 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 5% or more if it 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 Board under the BHC Act to acquire or retain more than 5% of that series.

23

Table of Contents

Any other person (other than a bank holding company) will be required to obtain the non-objection of the Federal Reserve Board 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.

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.

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 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

25

Table of Contents

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

26

Table of Contents

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 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 419,931,585 shares were outstanding as of September 30, 2014.

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 and series D 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 and series D 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. 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 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 (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.

DESCRIPTION OF PURCHASE CONTRACTS AND UNITS

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.

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.

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

Table of Contents

FORMS OF SECURITIES

Each debt security, depositary share, purchase contract, unit and warrant, and each capital security of the trusts will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Unless otherwise specified, 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, or capital securities of the trusts represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Global Securities

Registered Global Securities. We may issue the registered debt securities, depositary shares, purchase contracts, units and warrants, and capital securities 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 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, trust 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, trust 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 capital 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 Securities Exchange Act of 1934, and a successor depositary registered as a clearing agency under the Securities Exchange Act of 1934 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 and the selling security holders 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.

If any securities are sold pursuant to this prospectus by any persons other than us, we will, in a prospectus supplement, name the selling securityholders, indicate the nature of any relationship such holders have had with us or any of our affiliates during the three years preceding such offering, state the amount of securities of the class owned by such securityholder prior to the offering and the amount to be offered for the security holder’s account, and state the amount and (if one percent or more) the percentage of the class to be owned by such security holder after completion of the offering.

We or any selling securityholder 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 of 1933 and describe any commissions that we or any selling security holder 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:

Table of Contents

If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we and, if applicable, any selling securityholder 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.

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 and by any selling securityholder against certain civil liabilities, including liabilities under the Securities Act of 1933, and may be customers of, engage in transactions with or perform services for us or any selling securityholder 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 and/or the selling securityholders 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 Securities and Exchange Act of 1934, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. The applicable prospectus supplement may provide that the original issue date for your securities may be more than three 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 third business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than three 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.

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, 2013, and the effectiveness of State Street Corporation’s internal control over financial reporting as of December 31, 2013, 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, 2014 and March 31, 2013, for the three and six-month periods ended June 30, 2014 and June 30, 2013, and for the three and nine-month periods ended September 30, 2014 and September 30, 2013, 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 9, 2014, August 8, 2014 and November 7, 2014, included in State Street Corporation’s Quarterly Report on Form 10-Q for the quarters ended March 31, 2014, June 30, 2014 and September 30, 2014, respectively, and 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 reports 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 reports 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.
