State Street Corporation Third-Quarter 2015 Financial Highlights October 23, 2015

2 Forward-Looking Statements This presentation includes certain highlights of, and also material supplemental to, State Street Corporation’s (State Street’s) news release announcing its third-quarter 2015 financial results. That news release contains a more detailed discussion of many of the matters described in this presentation and is accompanied by detailed financial tables. This presentation is designed to be reviewed together with that news release, which is available on State Street’s website, at www.statestreet.com/stockholder, and is incorporated herein by reference. This presentation contains 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, investment portfolio performance and strategies, financial portfolio performance, dividend and stock purchase programs, expected outcomes of legal proceedings, market growth, acquisitions, joint ventures and divestitures and new technologies, services and opportunities, as well as regarding industry, regulatory, economic and market trends, initiatives and developments, the business environment and other matters. Terminology such as “outlook,” “expect,” “objective,” “intend,” “plan,” “forecast,” “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. These statements are not guarantees of future performance, are inherently uncertain, are based on current assumptions that are difficult to predict and involve a number of risks and uncertainties. Therefore, actual outcomes and results may differ materially from what is expressed in those statements, and those statements should not be relied upon as representing our expectations or beliefs as of any date subsequent to October 23, 2015. Important factors that may also affect future results and outcomes include, but are not limited to: The development, finalization and execution of our plan to accelerate the next phase of our transformation program to create cost efficiencies and to further digitize our interfaces with our clients in order to deliver more value, including identifying and implementing significant reductions in our cost structure and related restructuring and investment initiatives; the financial strength and continuing viability of the counterparties with which we or our clients do business and to which we have investment, credit or financial exposure, including, for example, the direct and indirect effects on counterparties of the sovereign- debt risks in the U.S., Europe and other regions; increases in the volatility of, or declines in the level of, our net interest revenue, changes in the composition or valuation of the assets recorded in our consolidated statement of condition (and our ability to measure the fair value of investment securities) and the possibility that we may change the manner in which we fund those assets; the liquidity of the U.S. and international securities markets, particularly the markets for fixed- income securities and inter-bank credits, and the liquidity requirements of our clients; the level and volatility of interest rates, the valuation of the U.S. dollar relative to other currencies in which we record revenue or accrue expenses and the performance and volatility of securities, credit, currency and other markets in the U.S. and internationally; the credit quality, credit-agency ratings and fair values of the securities in our investment securities portfolio, a deterioration or downgrade of which could lead to other-than-temporary impairment of the respective securities and the recognition of an impairment loss in our consolidated statement of income; our ability to attract deposits and other low-cost, short-term funding, our ability to manage levels of such deposits and the relative portion of our deposits that are determined to be operational under regulatory guidelines and our ability to deploy deposits in a profitable manner consistent with our liquidity requirements and risk profile; the manner and timing with which the Federal Reserve and other U.S. and foreign regulators implement changes to the regulatory framework applicable to our operations, including implementation of the Dodd-Frank Act, the Basel III final rule and European legislation (such as the Alternative Investment Fund Managers Directive, Undertakings for Collective Investment in Transferable Securities Directives and Markets in Financial Instruments Directive II); among other consequences, these regulatory changes impact the levels of regulatory capital we must maintain, acceptable levels of credit exposure to third parties, margin requirements applicable to derivatives, and restrictions on banking and financial activities. In addition, our regulatory posture and related expenses have been and wil l continue to be affected by changes in regulatory expectations for global systemically important financial institutions applicable to, among other things, risk management, liquidity and capital planning and compliance programs, and changes in governmental enforcement approaches to perceived failures to comply with regulatory or legal obligations; adverse changes in the regulatory ratios that we are required or will be required to meet, whether arising under the Dodd-Frank Act or the Basel III final rule, or due to changes in regulatory positions, practices or regulations in jurisdictions in which we engage in banking activities, including changes in internal or external data, formulae, models, assumptions or other advanced systems used in the calculation of our capital ratios that cause changes in those ratios as they are measured from period to period; increasing requirements to obtain the prior approval of the Federal Reserve or our other U.S. and non-U.S. regulators for the use, allocation or distribution of our capital or other specific capital actions or programs, including acquisitions, dividends and stock purchases, without which our growth plans, distributions to shareholders, share repurchase programs or other capital initiatives may be restricted; changes in law or regulation, or the enforcement of law or regulation, that may adversely affect our business activities or those of our clients or our counterparties, and the products or services that we sell, including additional or increased taxes or assessments thereon, capital adequacy requirements, margin requirements and changes that expose us to risks related to the adequacy of our controls or compliance programs; financial market disruptions or economic recession, whether in the U.S., Europe, Asia or other regions; our ability to promote a strong culture of risk management, operating controls, compliance oversight and governance that meet our expectations and those of our clients and our regulators; the results of, and costs associated with, governmental or regulatory inquiries and investigations, litigation and similar claims, disputes, or proceedings; the potential for losses arising from our investments in sponsored investment funds; the possibility that our clients will incur substantial losses in investment pools for which we act as agent, and the possibility of significant reductions in the liquidity or valuation of assets underlying those pools; our ability to anticipate and manage the level and timing of redemptions and withdrawals from our collateral pools and other collective investment products; the credit agency ratings of our debt and depository obligations and investor and client perceptions of our financial strength; adverse publicity, whether specific to State Street or regarding other industry participants or industry-wide factors, or other reputational harm; our ability to control operational risks, data security breach risks and outsourcing risks, our ability to protect our intellectual property rights, the possibility of errors in the quantitative models we use to manage our business and the possibility that our controls will prove insufficient, fail or be circumvented; our ability to expand our use of technology to enhance the efficiency, accuracy and reliability of our operations and our dependencies on information technology and our ability to control related risks, including cyber-crime and other threats to our information technology infrastructure and systems and their effective operation both independently and with external systems, and complexities and costs of protecting the security of our systems and data; our ability to grow revenue, manage expenses, attract and retain highly skilled people and raise the capital necessary to achieve our business goals and comply with regulatory requirements and expectations; changes or potential changes to the competitive environment, including changes due to regulatory and technological changes, the effects of industry consolidation and perceptions of State Street as a suitable service provider or counterparty; changes or potential changes in the amount of compensation we receive from clients for our services, and the mix of services provided by us that clients choose; our ability to complete acquisitions, joint ventures and divestitures, including the ability to obtain regulatory approvals, the ability to arrange financing as required and the ability to satisfy closing conditions; the risks that our acquired businesses and joint ventures will not achieve their anticipated financial and operational benefits or will not be integrated successfully, or that the integration will take longer than anticipated, that expected synergies will not be achieved or unexpected negative synergies or liabilities will be experienced, that client and deposit retention goals will not be met, that other regulatory or operational challenges will be experienced, and that disruptions from the transaction will harm our relationships with our clients, our employees or regulators; our ability to recognize emerging needs of our clients and to develop products that are responsive to such trends and profitable to us, the performance of and demand for the products and services we offer, and the potential for new products and services to impose additional costs on us and expose us to increased operational risk; changes in accounting standards and practices; and changes in tax legislation and in the interpretation of existing tax laws by U.S. and non-U.S. tax authorities that affect the amount of taxes due. Other important factors that could cause actual results to defer materially from those indicated by any forward-looking statements are set forth in our 2014 Annual Report on Form 10-K and our subsequent SEC filings. We encourage investors to read these filings, particularly the sections on risk factors, for additional information with respect to any forward-looking statements and prior to making any investment decision. The forward-looking statements contained in this presentation speak only as of the date hereof, October 23, 2015, and we do not undertake efforts to revise those forward-looking statements to reflect events after that date.

Operating-basis fee revenue growth outlook for 2015 compared to 2014 now likely lower than the previously communicated 4%-7% due to the recent drop in equity markets, particularly in emerging markets1 • Operating-basis fee revenue growth outlook for 2015 compared to 2014 now likely lower than the previously communicated 4%-7%: – Rapid decline in equity valuations globally, particularly in emerging markets, exacerbated impacts on revenue during 3Q15; average equity market levels are now lower than the average equity market assumptions communicated on January 23, 2015 – Stronger than anticipated US dollar: 2015 YTD average USD v Euro was 1.12 versus the 1.16 2015 full-year assumption communicated on January 23, 2015 – Multiple factors, including market conditions, equity market levels, foreign exchange rates, trading volumes and volatilities, investment flows and net new business, could impact our 4Q15 operating-basis fee revenue results relative to prior expectations • Previously communicated outlook for 2015 operating-basis total fee revenue growth outpacing operating-basis expense growth, each relative to 2014, by 200bps will be more challenging to achieve: – Our original assumption for achieving this outlook depended on total fee revenue growth of at least 4% in 2015, compared to 2014 • Expect full year 2015 operating-basis NIR to be near the lower end of $2.16B to $2.22B primarily reflecting our successful effort in reducing deposits and continued low market interest rates • Continue to expect an operating- basis effective tax rate of 30%-32% for full year 2015: – Operating-basis effective tax rate was 30.0% for the first nine months of 2015 – Expect an operating-basis effective tax rate of 33%-34% for 4Q15

16 Continue to focus on 2015 goals to deliver shareholder value in a challenging environment • While lower equity markets impacted 3Q15 results, we continue to focus on key priorities: – Delivering value-added solutions to our clients – Investing in growth initiatives – Diligently managing expenses – Returning capital to shareholders • Pleased with significant progress in reducing deposits in 3Q15

22 Footnote to Slide 14

23 Footnotes to slide 14 1Unless otherwise specified, all capital ratios referenced on slide 14 and elsewhere in this presentation refer to State Street Corporation, or State Street, and not State Street Bank and Trust Company, or State Street Bank. Refer to elsewhere in the Appendix to this presentation for a further description of these ratios and for reconciliations applicable to State Street’s estimated pro forma fully phased-in Basel III ratios. All capital ratios are presented as of quarter-end. The advanced approaches-based ratios (actual and estimated) presented in this presentation reflect calculations and determinations with respect to our capital and related matters, based on State Street and external data, quantitative formulae, statistical models, historical correlations and assumptions, collectively referred to as “advanced systems,” in effect and used by us for those purposes as of the respective date of each ratio’s first public announcement. Significant components of these advanced systems involve the exercise of judgment by us and our regulators, and these advanced systems may not, individually or collectively, precisely represent or calculate the scenarios, circumstances, outputs or other results for which they are designed or intended. Due to the influence of changes in these advanced systems, whether resulting from changes in data inputs, regulation or regulatory supervision or interpretation, State Street-specific or market activities or experiences or other updates or factors, we expect that our advanced systems and our capital ratios calculated in conformity with the Basel III framework will change and may be volatile over time, and that those latter changes or volatility could be material as calculated and measured from period to period. 2Provisions of the Basel III final rule, issued by U.S. banking regulators in July 2013, become effective under a transition t imetable which began on January 1, 2014. We have used the advanced approaches provided in the Basel III final rule to calculate our regulatory capital ratios beginning with the second quarter of 2014. Beginning with the first quarter of 2015, we began to also use the standardized approach provided in the Basel III final rule to calculate our regulatory capital ratios. The lower of our regulatory capital ratios calculated under the Basel III advanced approaches and those ratios calculated under the standard approach applied in the assessment of our capital adequacy for regulatory purposes. 3In 2014, U.S. banking regulators issued final rules implementing a supplementary leverage ratio, or SLR, for certain bank holding companies, like State Street, and their insured depository institution subsidiaries, like State Street Bank. We refer to these final rules as the SLR final rule. Under the SLR final rule, upon implementation as of January 1, 2018, (i) State Street Bank must maintain an SLR of at least 6% to be well capitalized under the U.S. banking regulators’ Prompt Corrective Action framework and (ii) if State Street maintains an SLR of at least 5%, it is not subject to limitations on distribution and discretionary bonus payments under the SLR final rule. Beginning with reporting for March 31, 2015, State Street is required to include SLR disclosures with its other Basel disclosures. 4The estimated pro forma fully phased-in Basel III common equity tier 1 ratios (advanced approaches and standardized approach) and the estimated pro forma fully phased-in supplementary leverage ratios as of June 30, 2015 and September 30, 2015 (as the case may be) are preliminary estimates by State Street, calculated, as applicable, in conformity with the advanced approaches or standardized approach, as the case may be, in the Basel III final rule, based on our interpretations of the Basel III final rule and the SLR final rule, as of July 24, 2015 and October 23, 2015, respectively, and as applied to our businesses and operations as of June 30, 2015 and September 30, 2015, respectively. The Basel III advanced approaches used both in the calculation of the common equity tier 1 ratio and the SLR will be fully phased in as of January 1, 2019 and January 1, 2018, respectively, as per Basel III phase-in requirements for capital. Refer to the addendum linked to this presentation for reconciliations of these ratios.

35 Non-GAAP Measures, Regulatory Capital Ratios and Reconciliations

36 Non-GAAP measures, regulatory capital ratios and reconciliations In addition to presenting State Street’s financial results in conformity with U.S. generally accepted accounting principles, referred to as GAAP, and used in the calculation of identified capital ratios, management also presents results on a non- GAAP, or “operating” basis, as it believes this presentation supports meaningful comparisons from period to period and the analysis of comparable financial trends with respect to State Street’s normal ongoing business operations. Management believes that operating-basis financial information, which reports revenue from non-taxable sources, such as interest revenue from tax-exempt investment securities and processing fees and other revenue associated with tax- advantaged investments, on a fully taxable-equivalent basis and excludes the impact of revenue and expenses outside of State Street’s normal course of business, facilitates an investor’s understanding and analysis of State Street’s underlying financial performance and trends in addition to financial information prepared and reported in conformity to GAAP. Management also believes that the use of other non-GAAP financial measures in the calculation of identified capital ratios is useful to understanding State Street’s capital position and is of interest to investors. Non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, financial measures determined in conformity with GAAP.
