Forward-Looking Statements This presentation contains forward-looking statements as defined by United States securities laws, including statements relating to our goals and expectations regarding our business, financial and capital condition (including without limitation, our capital ratios under Basel III), results of operations, investment portfolio performance and strategies, the financial and market outlook, governmental and regulatory initiatives and developments, and the business environment. Forward-looking statements are often, but not always, identified by such forward-looking terminology as "plan," "expect," “intend,” “forecast,” "look," "believe," "anticipate," "estimate," "seek,“ "may," "will," "trend," "target,” and "goal," or similar statements or variations of 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 March 6, 2013. Important factors that may affect future results and outcomes include, but are not limited to: 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 current sovereign-debt risks in Europe and other regions; financial market disruptions or economic recession, whether in the U.S., Europe, Asia or other regions; increases in the volatility of, or declines in the level of, our net interest revenue, changes in the composition 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 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, 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 the Dodd-Frank Act, the Basel II and Basel III capital and liquidity standards, and European legislation with respect to the levels of regulatory capital we must maintain, our credit exposure to third parties, margin requirements applicable to derivatives, banking and financial activities and other regulatory initiatives in the U.S. and internationally, including regulatory developments that result in changes to our structure or operating model, increased costs or other changes to how we provide services; adverse changes in the regulatory capital ratios that we are required to meet, whether arising under the Dodd-Frank Act, the Basel II or Basel III capital and liquidity standards 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 calculating 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 regulators for the use, allocation or distribution of our capital or other specific capital actions or programs, including acquisitions, dividends and equity purchases, without which our growth plans, distributions to shareholders, equity purchase programs or other capital initiatives may be restricted; changes in 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; our ability to promote a strong culture of risk management, operating controls, compliance oversight and governance that meet our expectations or those of our clients and our regulators; the credit agency ratings of our debt and depository obligations and investor and client perceptions of our financial strength; delays or difficulties in the execution of our previously announced Business Operations and Information Technology Transformation program, which could lead to changes in our estimates of the charges, expenses or savings associated with the planned program and may cause volatility of our earnings; the results of, and costs associated with, government investigations, litigation, and similar claims, disputes, or proceedings; 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 valuation of assets underlying those pools; adverse publicity or other reputational harm; dependencies on information technology, complexities and costs of protecting the security of our systems and difficulties with protecting our intellectual property rights; our ability to grow revenue, control expenses, attract and retain highly skilled people and raise the capital necessary to achieve our business goals and comply with regulatory requirements; 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; potential changes in how and in what amounts clients compensate us for our services, and the mix of services provided by us that clients choose; the 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 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 disynergies 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; our ability to anticipate and manage the level and timing of redemptions and withdrawals from our collateral pools and other collective investment products; our ability to control operating risks, data security breach risks, information technology systems risks and outsourcing risks, and 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; 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 differ materially from those indicated by any forward-looking statements are set forth in our 2012 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 news release speak only as of the date hereof, March 6, 2013, and we do not undertake efforts to revise those forward-looking statements to reflect events after that date. 2

Outlook for 2013: Revenue Drivers Revenue • $551BN in 2012 wins scheduled to be installed in 2013 • Early signs of re-risking by investors, if continued, is expected to benefit servicing and asset management fee revenues • Decline expected in NIR, with an operating-basis1 NIM of 130-140 bps, assuming interest rates and pre-payment speeds remain at current levels with modest balance sheet growth • Expect foreign exchange and securities finance revenues to be constrained 18 1 Results presented on an operating basis, a non-GAAP presentation. See Appendix for explanations of our non-GAAP financial measures.

Outlook for 2013: Expense Drivers Expenses • Expect to achieve incremental pre-tax expense savings from Business Operations and IT program of $220MN1 • Expect information systems and communications expenses to increase modestly from Q4 run rate as Business Operations and IT Transformation program continues • Estimated cost of accounting treatment of equity compensation for retirement-eligible employees, as well as payroll taxes, to be about $125MN in Q1 ’13 • Impact of the recent reduction in force expected to be $90MN annualized and realized over the next 18 months 19 Target Positive Operating Leverage2 on an Annual Basis for 2013 1 The full effect of the annual pre-tax, run-rate savings is not expected to be experienced until 2015.

Estimated annual pre-tax expense savings relate only to the Business Operations and Information Technology Transformation program, and are based on the projected improvement from 2010 operating expenses. Actual total expenses of the Company have increased since 2010, and may increase or decrease in the future, due to other factors. 2 Operating leverage is defined as the rate of growth of total revenue less the rate of growth of total expenses, each as determined on an operating basis.

Outlook for 2013: Balance Sheet Strategy Invest in High-Quality Assets • Invest through the cycle • Solid credit profile: ~90% AAA/AA-rated • Diversified by asset class and geography Manage Investment Portfolio Within Risk Appetite • Portfolio duration: ~1.5 years • Fixed-rate securities: ~45% of total investment portfolio • Target duration gap of between 0.25 and 0.50 years Maintain a Strong Capital Position • Manage the investment portfolio for capital efficiency, risk appetite and appropriate return Ongoing Management Expected Growth • 1% to 4% growth in earning assets Implications of Basel III • Given potential changes in Basel III rules, we continue to explore balance sheet and risk-management optimization, including investing in asset classes closely adjacent to our core business 20

Outlook for 2013: Operating-Basis1 (Non-GAAP) NIM Interest-Rate Assumptions • Worldwide administered rates remain unchanged through 2013 • Yield curves retain current shapes Investment Portfolio • To be managed in line with our balance sheet strategy Reinvestment Strategy • Expect about $20BN to mature or pay down for full-year 2013 • Reinvestment concentrated in capital-efficient asset classes, including mortgage-backed securities, U.S. and foreign asset-backed securities • NIM expected to be in range of 130 to 140 basis points NIR/NIM Sensitivities to Interest Rates • Lower interest rates: If interest rates decline 25 bps, NIR is expected to decline ~$50MN annually • Higher interest rates: Slowly rising rates modestly positive (~$39MN) assuming no change in client deposit behavior; if client deposit levels decline, the impact could be modestly negative, during the period of rising rates • “Normalized” interest rates: Structural NIM2 (3% Fed Funds, 5% 10-year U.S. Treasury) expected to be around 1.75% to 1.85% 21 2013 Operating-Basis NIM Expected to be in Range of 130 to 140 bps 1 Estimate presented on an operating basis, a non-GAAP presentation. Refer to the appendix included with this presentation for explanations of our non-GAAP financial measures. 2 Structural NIM assumes a normalized balance sheet.

Summary: 2013 Expectations 22 1 Operating leverage is defined as the rate of growth of total revenue less the rate of growth of total expenses, each as determined on an operating basis. • Grow servicing and management fee revenue • Assume continued softness in market-driven revenue • Work through low interest-rate environment • Continue to execute Business Operations and IT Transformation program and manage expenses diligently • Achieve positive operating leverage1 on an annual basis for 2013 • Return capital to shareholders in a plan consistent with State Street’s strong capital and earnings capacity

Appendix The foregoing presentation includes financial information presented on a GAAP basis as well as on a non-GAAP, or “operating basis.” Management measures and compares certain financial information on an operating basis, as it believes that 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 the 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 accordance with GAAP. Non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, financial measures determined in accordance with GAAP. 25
