Industrial loan and low cost deposit growth drive solid core business performance

Earnings Highlights

Customer focus drives solid core business performance while credit trends continue to improve

Regions’ first quarter 2011 earnings available to common shareholders of $17 million, or 1 cent per diluted share, marks the company’s second consecutive quarterly profit and included solid core business performance and improving credit trends. As pre-tax pre-provision net revenue on an adjusted basis rose by 16 percent over the first quarter of 2010, the company continued its progress toward sustainable profitability. Additionally this quarter, the net interest margin continued to expand, low-cost deposits increased, middle market commercial and industrial lending continued to grow and regulatory capital increased.

“We’re making solid headway towards sustainable profitability and key credit metrics continue to improve,” said Grayson Hall, president and chief executive officer. “The economic recovery is slow—especially in our southeastern markets—but our focus on customers is paying off. We’re taking market share, gaining new customers and expanding existing relationships. At the same time, we are improving productivity and efficiency and taking steps to expediently and prudently deal with credit problems and more stressed credit portfolios.”

The company’s inflows of non-performing loans declined 23 percent versus the previous quarter, as the main driver was a $168 million or 64 percent decline in inflows of land, condo, and single family loans. A substantial portion of the company’s non-performing loans continues to be current and paying as agreed. As of March 31, 2011, consistent with the previous quarter, 38 percent of Business Services’ non-performing loans were current and paying as agreed compared to 28 percent a year ago. Loans paying current have cash flow and therefore the company expects these will result in less costly resolution versus non-income producing properties.

During the first quarter, net charge-offs declined $201 million, or 29 percent linked quarter, to $481 million or an annualized 2.37 percent of average loans and the provision for loan losses essentially matched net charge-offs. The current allowance for loan losses to loans ratio increased 8 basis points to 3.92 percent, while the loan loss allowance coverage of non-performing loans increased to 1.03x at March 31, 2011.

Focus on customers remains a strategic priority; C&I lending continues to grow

Retaining and profitably growing customers and core businesses is a key factor in returning the company to sustainable profitability. According to a recent report issued by the Temkin Group, Regions ranked as the top bank for customer experience, and as one of the top companies in America for customer service across all industries. The company has also received national awards from Greenwich & Associates for overall client satisfaction in middle market and for relationship manager performance in the company’s small business lending.

Overall, both ending and average loans declined 2 percent. Ending commercial and industrial grew 3 percent, offset by the company’s continued de-risking of its Investor Real Estate portfolio. The company is still targeting to reduce this portfolio to no more than 100 percent of the bank’s total regulatory capital, which approximates $14 billion today.

In the first quarter growth in lending to the middle market commercial and industrial customer segment continued, as average loans increased 4 percent linked-quarter in this segment and the company experienced increases in 65 percent of its markets. This was driven by customers’ increasing their investments in capital expenditures and inventory as well as mergers and acquisitions; both new client acquisition and line utilization are contributing to this growth. Total commercial and industrial outstandings have now grown for nine consecutive months. Line utilization rose to 41.7 percent as of March 31—up from year-end 2010’s 40.3 percent, the highest since September 2009; however, utilization still remains well below Regions’ historical normal rate.

The company also continues to execute on its plans to grow consumer loans, which includes an increased emphasis on indirect lending, cash banking product solutions, and continuing to leverage our customer loyalty and extensive branch network to retain and attract new customers.

Regions has remained an active lender in the current environment, having made new or renewed loan commitments totaling $13.3 billion during the first quarter, primarily driven by residential first mortgage production and lending to commercial customers, including those operating small businesses.

Net interest margin expansion driven by improving funding mix and slower prepayments resulting in lower investment portfolio premium amortization

Regions’ funding mix continued to improve during the quarter, as average low-cost deposits grew $1 billion or 1 percent linked quarter, driving a 7 basis point gain in net interest margin to 3.07 percent. During the first quarter, deposit costs declined 5 basis points to 0.59 percent. Slower prepayment rates and the resulting decrease in premium amortization on mortgage-backed securities and lower average cash balances at the Federal Reserve were also drivers of the increase. Overall, net interest income declined 2 percent linked quarter, but was 4 percent higher on a year-over-year basis at $863 million.

While some deposit re-pricing opportunity is available, the company believes that future margin expansion depends primarily on continued improvement in loan spreads and change in loan mix. The company remains disciplined with pricing on new loans, ensuring the company is being appropriately paid on a risk-adjusted basis. The company’s balance sheet is modestly asset sensitive and accordingly net interest income and net interest margin would increase with rising interest rates.

Modest decline in non-interest revenues

Non-interest revenue totaled $843 million and included $82 million in securities gains. On an adjusted basis, non-interest revenues declined 4 percent linked quarter, primarily driven by a 14 percent decline in brokerage and investment banking revenue, which benefited from several sizable investment banking transactions in the prior quarter, as well as other seasonal factors (see non-GAAP reconciliation in Financial Supplement). Income from service charges of $287 million was down slightly on both a linked quarter and a year-over-year basis. However, the company continues to see strong debit card volume and fee-based account growth, which is serving to offset the negative impact of Regulation E. Although mortgage originations were down on a linked quarter basis, resulting in a $6 million decline in mortgage income, they remain strong compared to historical standards, increasing 13 percent compared to the same period a year ago.

Non-interest expenses improve

Non-interest expense totaled $1.2 billion for the quarter. Non-interest expenses decreased 8 percent linked quarter, driven by declines in professional and legal fees, salaries and benefits

expense, other real estate owned and loans held for sale expenses and a $55 million debt extinguishment cost in the prior quarter. Credit-related expenses are a significant component of non-interest expenses, ranging between $300 million and $400 million annually, and are expected to subside as the credit cycle eases. The company remains committed to targeting all areas of staffing, occupancy, discretionary spending, incentives, and credit-related expenses. Customers will continue to be at the center of every decision, and any changes will maintain focus on service quality and meeting their needs.

Regulatory reform

Depending on ultimate regulatory changes related to interchange fees and the timing of their implementation, the company faces additional fee income challenges in 2011. Regions derived $346 million from this revenue stream in 2010 and while it is premature to assess the proposals’ impact on these fees, the potential effect could be significant.

The company is encouraged by the Federal Reserve’s announcement of a delay in issuing a final rule on interchange fees. The company is also encouraged by the bills introduced in both the House and Senate with bipartisan support that would delay implementation of proposed reductions in interchange fees proposed by the Durbin Amendment, giving the industry more time to analyze pricing and consequences of the proposal. The company is hopeful that the review process and outcome will be more rational than the plan currently proposed. The desired approach is one that takes into account the banking industry’s total costs of delivering debit cards, such as losses related to fraud, and also considers the potential negative effect to the consumer on debit card availability.

Regardless of the outcome, the company is working to develop mitigation strategies to rationalize its business under the proposed rule changes. For instance, Regions began migrating accounts from free to fee eligible last May, and now all checking accounts are fee eligible. Also, the company continues to see a record level of penetration with its new checking account customers, who are electing to have a debit card 90 percent of the time.

Strong capital and liquidity

Tier 1 common and Tier 1 ratios remained solid, ending the quarter at an estimated 7.9 and 12.5 percent, respectively, and on a Basel III pro-forma basis were 7.5 and 11.1 percent, above the respective 7 percent and 8.5 percent minimum requirements. The company’s liquidity position at both the bank and the holding company remains strong as well. As of March 31, 2011, the company’s loan-to-deposit ratio was 84.4 percent.

Use of non-GAAP financial measures

Page two of this earnings release presents Tier 1 common risk-based ratio and tangible common equity (non-GAAP). Page five of the financial supplement shows additional ratios based on return on average assets, tangible common stockholders’ equity, efficiency ratio, as well as the Tier 1 common risk-based ratio and computations of earnings and certain other financial measures excluding the regulatory charge (non-GAAP). Tangible common stockholders’ equity ratios have become a focus of some investors, and management believes they may assist investors in analyzing the capital position of the company absent the effects of intangible assets and preferred stock. 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 Supervisory Capital Assessment Program, these regulators began 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 tangible common stockholders’ equity and/or the Tier 1 common equity measure. Because tangible common stockholders’ equity and Tier 1 common equity are not formally defined by GAAP or codified in the federal banking regulations, these measures are considered to be non-GAAP financial measures and other entities may calculate them differently than Regions’ disclosed calculations. Since analysts and banking regulators may assess Regions’ capital adequacy using tangible common stockholders’ equity and 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 bank’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 financial measures have inherent limitations, are not required to be uniformly applied and are not audited. To mitigate these limitations, Regions has policies and procedures in place to identify and address expenses that qualify for non-GAAP presentation, including authorization and system controls to ensure accurate period to period comparisons. 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 earnings that excludes the regulatory charge does not represent the amount that effectively accrues directly to stockholders (i.e. the regulatory charge is a reduction in earnings and stockholders’ equity).

See page 8 of the supplement to this earnings release for the computation of pre-tax pre-provision net revenue (GAAP) to adjusted pre-tax pre-provision net revenue (non-GAAP). See pages 25 and 26 of the supplement to this earnings release for 1) computation of GAAP net income (loss) available to common shareholders, earnings (loss) per common share and return on average assets to non-GAAP financial measures, 2) a reconciliation of average and ending stockholders’ equity (GAAP) to average and ending

tangible common stockholders’ equity (non-GAAP), 3) a reconciliation of stockholders’ equity (GAAP) to Tier 1 capital (regulatory) and to Tier 1 common equity (non-GAAP), 4) a reconciliation of non-interest expense (GAAP) to adjusted non-interest expense (non-GAAP) 5) a reconciliation of non-interest revenue (GAAP) to adjusted non-interest revenue (non-GAAP) and 6) a computation of the efficiency ratio (non-GAAP).
