Summary Performance Discussion

“We are pleased with the quarter’s financial results which reflect steady growth in a number of key strategic areas including loans, deposits, and customer relationships. This demonstrates the continued benefits from successfully executing our strategic plan. This quarter was negatively impacted by an increase in healthcare and regulatory costs,” said Stephen D. Steinour, chairman, president and chief executive officer. “At the core of our strategic plan remains a differentiated approach to banking, coupled with investing in products and services that are driving growth and improvement in the stability of our long-term profitability.”

Net income in the third quarter was $167.8 million, up $15.1 million, or 10%, from $152.7 million in the prior quarter. The primary drivers of the increase were a $21.0 million, or 43%, decrease in provision for income taxes and a $7.2 million, or 3%, increase in noninterest income that were partially offset by a $14.0 million, or 3%, increase in noninterest expense. The decrease in provision for income taxes reflected the only significant item for the quarter, a $19.5 million state deferred tax valuation allowance benefit.

Net interest income increased $0.8 million, or less than 1%, from the prior quarter. This reflected a $0.3 billion, or 1% (2% annualized), increase in average earning assets and a 4 basis point decrease in the fully-taxable equivalent net interest margin (NIM) to 3.38%. The linked-quarter decrease in the NIM reflected the negative impact of a 10 basis point decline of the yield on earnings assets, 6 basis points of which were related to the yield on loans. This was partially offset by the benefit of a 6 basis point reduction in total funding costs. Average noninterest bearing deposits increased $0.3 billion, or 8% annualized, and represented 27% of total deposits.

The $0.3 billion increase in average earning assets was driven by the $1.4 billion increase in average loans held for sale and a $0.2 billon, 6% annualized, increase in average commercial and industrial loans (C&I). That was partially offset by the $0.9 billion decrease in average automobile loans, reflecting the prior quarter’s reclassification of $1.3 billion of automobile loans into held for sale, and a $0.4 billion decrease in commercial real estate loans.

Average total core deposits increased $1.0 billion, or 9% annualized, reflecting a $1.3 billion, or 40% annualized, increase in money market deposits and a $0.3 billion, or 9% annualized, increase in noninterest bearing demand deposits. These were partially offset by the $0.5 billion, or 29% annualized, decrease in core certificates of deposit (CDs) as customers were actively transitioned from CDs into more flexible money market accounts or other investment based solutions. Through our strategic focus on growing consumer households and commercial relationships by earning their primary checking (demand deposit) accounts, we continue to improve our overall funding mix. As previously disclosed, there remains over $1.0 billion of demand deposits from several larger relationships that are considered nonpermanent in nature.

Total noninterest income increased $7.2 million, or 3%, from the prior quarter. This included a $6.3 million, or 16%, increase in mortgage banking income and a $3.8 million increase in securities gains. Gain on sale of loans increased $2.5 million, or 60%, due to the sale of $0.2 billion of automobile loans that we classified as held for sale at the end of the prior quarter. These positive impacts were partially offset by a $4.4 million, or 16%, decrease in other income as the prior quarter included a gain on the sale of affordable housing investments.

Commenting on revenue trends, Steinour said, “The third quarter results clearly showed the continued benefit of the investment we have made over the preceding three years. Adding over 250,000 consumer households, a 27% increase, and 26,000 commercial relationships, or 21% increase, since the first quarter of 2010 has allowed Huntington to grow quarterly total revenue by more than $59 million even with the negative impacts from the low absolute level of interest rates, the flat shape of the yield curve, and the reduction of over $25 million of revenue per quarter due to the Durbin amendment and implementation of changes to Regulation E. Not only are we gaining customers, we are selling deeper with 76% of consumer checking account households and 33% of commercial relationships now with 4 or more products or services. Strategic investments have a maximum of two years to break even with many reaching that level in the first year. A portion of our strategic investments remain in the early stages, such as our strategy to build over 180 in-store full service branches. The in-store branches are on target with the estimated aggregate impact to operating income negligible next year and positive in 2014.”

Noninterest expense increased $14.0 million, or 3%, from the prior quarter. This included a $4.7 million, or 2%, increase in personnel costs primarily reflecting higher healthcare costs and a $4.4 million increase in the cost associated with early extinguishment of debt including the trust preferred securities (TruPS) that were redeemed during the quarter. Noninterest expense included $4.5 million of expense related to the development of infrastructure and systems to support the Federal Reserve CCAR process.

The provision for credit losses increased $0.5 million, or 1%, from the prior quarter. This reflected a $20.9 million, or 25%, increase in net charge-offs (NCOs) to $105.1 million, or an annualized 1.05% of average total loans and leases, from $84.2 million, or an annualized 0.82%, in the prior quarter. Of this quarter’s NCOs, $33.0 million related to regulatory guidance requiring consumer loans discharged under Chapter 7 bankruptcy to be charged down to collateral value. Approximately 90% continue to make payments as scheduled. Partially offsetting the increase in NCOs were significant improvement in asset quality trends, resulting in lower calculated reserves. Criticized commercial loans declined by $223 million, or 11%, in the quarter, and specific reserves associated with impaired commercial loans also declined.

The period-end allowance for credit losses (ACL) as a percentage of total loans and leases decreased to 2.09% from 2.28% in the prior quarter. The ACL as a percentage of period end total nonaccrual loans (NALs) was essentially unchanged, decreasing 3 percentage points to 189%. NALs declined by $29.1 million, or 6%, to $445.0 million, or 1.11% of total loans, during the quarter despite a $63 million increase associated with the revised treatment of Chapter 7 bankruptcy consumer loans.

Capital, our Tier 1 common risk-based capital ratio at September 30, 2012, was 10.28%, up from 10.08% at June 30, 2012, and our tangible common equity ratio increased to 8.74% from 8.41% over this same period. The regulatory Tier 1 risk-based capital ratio at September 30, 2012, was 11.88%, down from 11.93%, at June 30, 2012. This decline reflected the capital actions taken throughout the quarter, which are discussed below.

Over the quarter, and consistent with planned capital actions, redemption of $150 million of trust preferred securities (TruPS) was announced and 3.7 million common shares were repurchased at an average price of $6.68 per share. The weighted average coupon of the remaining $300 million of TruPS is LIBOR + 1.02%. Commenting on capital, Steinour said, “Reinvesting excess capital to grow the business organically remains our first priority. Importantly, through dividends and share repurchases, we have the flexibility, subject to market conditions, to return a meaningful amount of our earnings to the owners of the company.”

Expectations

“We continue to see positive trends within our Midwest markets relative to the broader United States. Nevertheless, broad based customer sentiment began to change late in the quarter. Customers have increased concerns, in the near term, regarding the US economy as we approach the election and scheduled impacts of the Budget Control Act of 2011. We are optimistic that once permanent solutions are in place, the strength of the Midwest and the soundness of our strategy will continue to drive growth and improved profitability,” said Steinour.

For the next several quarters, average net interest income is expected to be relatively stable from the third quarter’s level as we anticipate an increase in total loans, excluding the impacts of any future loan securitizations. Those benefits to net interest income are expected to be mostly offset, however, by downward NIM pressure due to the anticipated competitive pressures on loan pricing, as well as lower rate securities through reinvestment, and declining positive impacts from deposit repricing. The C&I portfolio is expected to continue to show growth. Although, given the most recent trend, we are expecting near-term growth to be slower than the strong growth we experienced earlier this year. Our C&I sales pipeline remains robust with much of this reflecting the positive impact from our strategic initiatives, focused OCR sales process, and continued support of middle market and small business lending in the Midwest. We will continue to evaluate the use of automobile loan securitizations to limit total on-balance sheet exposure due to our expectation of continued strong levels of originations. On October 11, a $1.0 billion automobile loan securitization, with an approximate $17 million gain, was completed. Residential mortgages and home equity loan balances are expected to be relatively stable in response to the proposed capital rules recently released by our regulators. CRE loans likely will experience declines from current levels.

Excluding potential future automobile loan securitizations, we anticipate the increase in total loans will modestly outpace growth in total deposits. This reflects our continued focus on our overall cost of funds and the continued shift towards low- and no-cost demand deposits and money market deposit accounts.

Noninterest income, excluding the impact of any automobile loan sale or security gains and any net MSR impact, is expected to be relatively stable at current levels. Continued growth in new customers and increased contribution from higher cross-sell are expected to be offset by a slowdown in mortgage banking activity.

Noninterest expense is expected to modestly increase above the 2012 third quarter level. For the full year, we continue to anticipate positive operating leverage and modest improvement in our expense efficiency ratio. Additional regulatory costs and expenses associated with strategic actions, including the planned opening of over 80 in-store branches this year, are expected to be partially offset by our focus on improving expense efficiencies throughout the company.

Credit quality is expected to experience improvement. The level of provision for credit losses in the first three quarters of the year was at the low end of our long-term expectation, and we expect some quarterly volatility given the absolute low level of the provision for credit losses and the uncertain and uneven nature of the economic recovery.

We anticipate the effective tax rate for the 2012 fourth quarter to approximate 24% to 26%, which includes permanent tax benefits primarily related to tax-exempt income, tax-advantaged investments, and general business credits.

Basis of Presentation

Use of Non-GAAP Financial Measures

This document may contain GAAP financial measures and non-GAAP financial measures where management believes it to be helpful in understanding Huntington’s results of operations or financial position. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found in this document, the 2012 Third Quarter Performance Discussion and Quarterly Financial Review supplements to this document, the third quarter earnings conference call slides, or the Form 8-K related to this document, all of which can be found on Huntington’s website at www.huntington-ir.com.

Annualized data

Certain returns, yields, performance ratios, or quarterly growth rates are presented on an “annualized” basis. This is done for analytical and decision-making purposes to better discern underlying performance trends when compared to full year or year-over-year amounts. For example, loan and deposit growth rates, as well as net charge-off percentages, are most often expressed in terms of an annual rate like 8%. As such, a 2% growth rate for a quarter would represent an annualized 8% growth rate.

Fully-taxable equivalent interest income and net interest margin

Income from tax-exempt earning assets is increased by an amount equivalent to the taxes that would have been paid if this income had been taxable at statutory rates. This adjustment puts all earning assets, most notably tax-exempt municipal securities and certain lease assets, on a common basis that facilitates comparison of results to results of competitors.

Earnings per share equivalent data

Significant income or expense items may be expressed on a per common share basis. This is done for analytical and decision-making purposes to better discern underlying trends in total corporate earnings per share performance excluding the impact of such items. Investors may also find this information helpful in their evaluation of the company’s financial performance against published earnings per share mean estimate amounts, which typically exclude the impact of Significant Items. Earnings per share equivalents are usually calculated by applying a 35% effective tax rate to a pre-tax amount to derive an after-tax amount, which is divided by the average shares outstanding during the respective reporting period. Occasionally, when the item involves special tax treatment, the after-tax amount is disclosed separately, with this then being the amount used to calculate the earnings per share equivalent.
