FORWARD-LOOKING STATEMENTS

This presentation may include forward-looking statements which reflect Regions’ current views with respect to future events and financial performance. The Private Securities Litigation Reform Act of 1995 (“the Act”) provides a “safe harbor” for forward-looking statements which are identified as such and are accompanied by the identification of important factors that could cause actual results to differ materially from the forward-looking statements. For these statements, we, together with our subsidiaries, claim the protection afforded by the safe harbor in the Act. Forward-looking statements are not based on historical information, but rather are related to future operations, strategies, financial results or other developments. Forward-looking statements are based on management’s expectations as well as certain assumptions and estimates made by, and information available to, management at the time the statements are made. Those statements are based on general assumptions and are subject to various risks, uncertainties and other factors that may cause actual results to differ materially from the views, beliefs and projections expressed in such statements. These risks, uncertainties and other factors include, but are not limited to, those described below:

› The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) became law on July 21, 2010, and a number of legislative, regulatory and tax proposals remain pending. Additionally, the U.S. Treasury and federal banking regulators continue to implement, but are also beginning to wind down, a number of programs to address capital and liquidity in the banking system. Future and proposed rules, including those that are part of the Basel III process, could require banking institutions to increase levels of capital. All of the foregoing may have significant effects on Regions and the financial services industry, the exact nature of which cannot be determined at this time.

› Regions’ ability to mitigate the impact of the Dodd-Frank Act on debit interchange fees through revenue enhancements and other revenue measures, which will depend on various factors, including the acceptance by our customers of modified fee structures for Regions’ products and services.

› Possible additional loan losses, impairment of goodwill and other intangibles, and adjustment of valuation allowances on deferred tax assets and the impact on earnings and capital.

› Possible changes in interest rates may increase funding costs and reduce earning asset yields, thus reducing margins. Increases in benchmark interest rates would also increase debt service requirements for customers whose terms include a variable interest rate, which may negatively impact the ability of borrowers to pay as contractually obligated.

› Possible changes in general economic and business conditions in the United States in general and in the communities Regions serves in particular, including any prolonging or worsening of the current unfavorable economic conditions including unemployment levels.

› Possible changes in the creditworthiness of customers and the possible impairment of the collectability of loans.

› Possible changes in trade, monetary and fiscal policies, laws and regulations and other activities of governments, agencies, and similar organizations, may have an adverse effect on business.

› Possible stresses in the financial and real estate markets, including possible continued deterioration in property values.

› Regions’ ability to manage fluctuations in the value of assets and liabilities and off-balance sheet exposure so as to maintain sufficient capital and liquidity to support Regions’ business.

› Regions’ ability to expand into new markets and to maintain profit margins in the face of competitive pressures.

› Regions’ ability to develop competitive new products and services in a timely manner and the acceptance of such products and services by Regions’ customers and potential customers.

› Regions’ ability to keep pace with technological changes.

› Regions’ ability to effectively manage credit risk, interest rate risk, market risk, operational risk, legal risk, liquidity risk, and regulatory and compliance risk.

› Regions’ ability to ensure adequate capitalization which is impacted by inherent uncertainties in forecasting credit losses.

› The cost and other effects of material contingencies, including litigation contingencies, and any adverse judicial, administrative or arbitral rulings or proceedings.

› The effects of increased competition from both banks and non-banks.

› The effects of geopolitical instability and risks such as terrorist attacks.

› Possible changes in consumer and business spending and saving habits could affect Regions’ ability to increase assets and to attract deposits.

› The effects of weather and natural disasters such as floods, droughts, wind, tornados and hurricanes, and the effects of man-made disasters.

› Possible downgrades in ratings issued by rating agencies.

› Potential dilution of holders of shares of Regions’ common stock resulting from the U.S. Treasury’s ownership of a warrant to purchase up to 48,253,677 shares of common stock.

› Potential dilution of holders of shares of common stock resulting from any future efforts by Regions to raise additional capital.

› Possible changes in the speed of loan prepayments by Regions’ customers and loan origination or sales volumes.

› Possible acceleration of prepayments on mortgage-backed securities due to low interest rates and the related acceleration of premium amortization on those securities.

› The effects of problems encountered by larger or similar financial institutions that adversely affect Regions or the banking industry generally.

› Regions’ ability to receive dividends from its subsidiaries.

› The effects of the failure of any component of Regions’ business infrastructure which is provided by a third party.

› Changes in accounting policies or procedures as may be required by the Financial Accounting Standards Board or other regulatory agencies.

› With regard to the sale of Morgan Keegan the possibility of business disruption following the transaction; reputational risks and the reaction of customers and counterparties to the transaction; and occurrences which could cause post-closing adjustments to the purchase price.

› The effects of any damage to Regions’ reputation resulting from developments related to any of the items identified above.

› The foregoing list of factors is not exhaustive. For discussion of these and other factors that may cause actual results to differ from expectations, look under the captions “Forward-Looking Statements” and “Risk Factors” in Regions’ Annual Report on Form 10-K for the year ended December 31, 2011.

› The words “believe,” “expect,” “anticipate,” “project,” and similar expressions often signify forward-looking statements. You should not place undue reliance on any forward-looking statements, which speak only as of the date made. We assume no obligation to update or revise any forward-looking statements that are made from time to time.

NON-GAAP RECONCILIATION: NET INCOME / (LOSS) AND EARNINGS PER SHARE

The tables below and on the next slide present computations of earnings (loss) and certain other financial measures, excluding goodwill impairment and regulatory charge and related tax benefit (non-GAAP). The goodwill impairment charge and the regulatory charge and related tax benefit are included in financial results presented in accordance with generally accepted accounting principles (GAAP). A table also presents computations of full year and quarterly pre-tax pre-provision income (non-GAAP). Regions believes that the exclusion of the goodwill impairment and the regulatory charge and related tax benefit in expressing earnings (loss) and certain other financial measures, including “earnings (loss) per common share, excluding goodwill impairment and regulatory charge and related tax benefit” provides a meaningful base for period-to-period comparisons, which management believes will assist investors in analyzing the operating results of the Company and predicting future performance. These non-GAAP financial measures are also used by management to assess the performance of Regions’ business because management does not consider the goodwill impairment and regulatory charge and related tax benefit to be relevant to ongoing operating results. Management and the Board of Directors utilize these non-GAAP financial measures for the following purposes: preparation of Regions’ operating budgets; monthly financial performance reporting; monthly close-out “flash” reporting of consolidated results (management only); and presentations to investors of company performance. Management uses these measures to monitor performance and believes these measures provide meaningful information to investors.

(1) There are no preferred shares allocable to discontinued operations.

(2) In the second quarter of 2010, Regions recorded a $200 million charge to account for a probable, reasonably estimable loss related to a pending settlement of regulatory matters. At that time, Regions assumed that the entire charge would be non-deductible for income tax purposes. $75 million of the regulatory charge relates to continuing operations. The settlement was finalized during the second quarter of 2011. At the time of settlement, Regions had better information related to tax implications. Approximately $125 million of the settlement charge will be deductible for federal income tax purposes. Accordingly, during the second quarter of 2011, Regions adjusted federal income taxes to account for the impact of the deduction. The adjustment reduced Regions’ provision for income taxes by approximately $44 million for the second quarter of 2011, of which approximately $17 million relates to continuing operations.

REGIONS 13

NON-GAAP RECONCILIATION: PRE-TAX PRE-PROVISION INCOME

The Pre-Tax Pre-Provision Income from Continuing Operations table above presents computations of pre-tax pre-provision income from continuing operations excluding certain adjustments (non-GAAP). Regions believes that the exclusion of these adjustments provides a meaningful base for period-to-period comparisons, which management believes will assist investors in analyzing the operating results of the Company and predicting future performance. These non-GAAP financial measures are also used by management to assess the performance of Regions’ business. It is possible that the activities related to the adjustments may recur; however, management does not consider the activities related to the adjustments to be indications of ongoing operations. Regions believes that presentation of these non-GAAP financial measures will permit investors to assess the performance of the Company on the same basis as that applied by management. Non-GAAP financial measures have inherent limitations, are not required to be uniformly applied and are not audited. Although these non-GAAP financial measures are frequently used by stakeholders in the evaluation of a company, they have limitations as analytical tools, and should not be considered in isolation, or as a substitute for analyses of results as reported under GAAP. In particular, a measure of income that excludes certain adjustments does not represent the amount that effectively accrues directly to stockholders.

In the table below non-interest expense (GAAP) and non-interest income (GAAP) are presented excluding certain adjustments to arrive at adjusted non-interest expense (non-GAAP) and non-interest income (non-GAAP). Net interest income on a fully taxable-equivalent basis (GAAP) and non-interest income are added together to arrive at total revenue (GAAP).

NON-GAAP RECONCILIATION: TIER 1 COMMON

The following table provides a reconciliation of stockholder’s equity to “Tier 1 common equity” (non-GAAP). Traditionally, the Federal Reserve and other banking regulatory bodies have assessed a bank’s capital adequacy based on Tier 1 capital, the calculation of which is codified in federal banking regulations. In connection with the Company’s Comprehensive Capital Assessment and Review (“CCAR”), these regulators are supplementing their assessment of the capital adequacy of a bank based on a variation of Tier 1 capital, known as Tier 1 common equity. While not codified, analysts and banking regulators have assessed Regions’ capital adequacy using the Tier 1 common equity measure. Because Tier 1 common equity is not formally defined by GAAP or codified in the federal banking regulations, this measure is considered to be non-GAAP and other entities may calculate it differently than Regions’ disclosed calculations. Since analysts and banking regulators may assess Regions’ capital adequacy using TIer 1 common equity, we believe that it is useful to provide investors the ability to assess Regions’ capital adequacy on these same bases.

Tier 1 common equity is often expressed as a percentage of risk-weighted assets. Under the risk-based capital framework, a company’s balance sheet assets and credit equivalent amounts of off-balance sheet items are assigned to one of four broad risk categories. The aggregated dollar amount in each category is then multiplied by the risk-weighted category. The resulting weighted values from each of the four categories are added together and this sum is the risk-weighted assets total that, as adjusted, comprises the denominator of certain risk-based capital ratios. Tier 1 capital is then divided by this denominator (risk-weighted assets) to determine the Tier 1 capital ratio. Adjustments are made to Tier 1 capital to arrive at Tier 1 common equity. Tier 1 common equity is also divided by the risk-weighted assets to determine the Tier 1 common equity ratio. The amounts disclosed as risk-weighted assets are calculated consistent with banking regulatory requirements.

NON-GAAP RECONCILIATION: BASEL III

The following table provides calculations of Tier 1 capital and Tier 1 common, based on Regions’ current understanding of Basel III requirements. Regions currently calculates its risk-based capital ratios under guidelines adopted by the Federal Reserve based on the 1988 Capital Accord (“Basel I”) of the Basel Committee on Banking Supervision (the “Basel Committee”). In December 2010, the Basel Committee released its final framework for Basel III, which will strengthen international capital and liquidity regulation. When implemented by U.S. bank regulatory agencies and fully phased-in, Basel III will change capital requirements and place greater emphasis on common equity. Implementation of Basel III will begin on January 1, 2013, and will be phased in over a multi-year period. The U.S. bank regulatory agencies have not yet finalized regulations governing the implementation of Basel III. Accordingly, the calculations provided below are estimates, based on Regions’ current understanding of the framework, including the Company’s reading of the requirements, and informal feedback received through the regulatory process. Regions’ understanding of the framework is evolving and will likely change as the regulations are finalized. Because the Basel III implementation regulations are not formally defined by GAAP and have not yet been finalized and codified, these measures are considered to be non-GAAP financial measures, and other entities may calculate them differently from Regions’ disclosed calculations. Since analysts and banking regulators may assess Regions’ capital adequacy using the Basel III framework, we believe that it is useful to provide investors the ability to assess Regions’ capital adequacy on the same basis.

(1) Under Basel III, regulatory capital must be reduced by purchased credit card relationship intangible assets. These assets are partially allowed in Basel I capital.

(2) Regions continues to develop systems and internal controls to precisely calculate risk-weighted assets as required by Basel III. The amount included above is a reasonable approximation, based on our understanding of the requirements.

NON-GAAP RECONCILIATION: TIER 1 CAPITAL

Regions Series A preferred stock was retired on April 4, 2012. The following tables present the calculations of Tier 1 capital and the Tier 1 capital ratio, adjusted as if the retirement occurred on the last day of the quarter for each period presented. The amount retired includes the Series A preferred stock plus the remaining balance of the related discount. The tables do not include an adjustment for the retirement of the warrant to purchase 48.3 million shares of Regions common stock at $10.88 as this amount cannot be estimated at this time.
