“Third quarter and year-to-date 2013 earnings continue to be strong,” stated Richard M. Adams, United’s Chairman of the Board and Chief Executive Officer. “United also continues to be well capitalized based upon regulatory guidelines, and our asset quality outperforms our peers. United is one of only two major banking companies in the USA to have increased its dividend to shareholders for 39 consecutive years.”

Third quarter of 2013 results produced a return on average assets of 1.04% and a return on average equity of 8.64%, respectively. For the first nine months of 2013, United’s return on average assets was 1.05% while the return on average equity was 8.72%. United’s annualized returns on average assets and average equity were 0.92% and 7.76%, respectively, for the third quarter of 2012 while the returns on average assets and average equity was 0.97% and 8.32%, respectively, for the first nine months of 2012.

The results for the first nine months of 2013 included noncash, before-tax, other-than-temporary impairment charges of $971 thousand on certain investment securities. No noncash, before-tax, other-than-temporary impairment charges were recognized during the third quarter of 2013. Included in the results for the third quarter and first nine months of 2012 were noncash, before-tax, other-than-temporary impairment charges of $2.3 million and $5.4 million, respectively, on certain investment securities. The results for the third quarter and first nine months of 2012 also included an accrual of $3.3 million with respect to a settlement of claims asserted in class actions against United Bank, Inc. of West Virginia.

United’s asset quality continues to outperform its peers. United’s percentage of nonperforming loans to loans, net of unearned income of 1.26% at September 30, 2013 compares favorably to the most recently reported percentage of 2.13% at June 30, 2013 for United’s Federal Reserve peer group. At September 30, 2013, nonperforming loans were $83.1 million, down from nonperforming loans of $92.8 million or 1.43% of loans, net of unearned income, at December 31, 2012. As of September 30, 2013, the allowance for loan losses was $74.6 million or 1.13% of loans, net of unearned income, which was comparable to $73.9 million or 1.13% of loans, net of unearned income, at December 31, 2012. Total nonperforming assets of $125.7 million, including OREO of $42.5 million at September 30, 2013, represented 1.48% of total assets which also compares favorably to the most recently reported percentage of 1.73% at June 30, 2013 for United’s Federal Reserve peer group.

Noninterest income for the third quarter of 2013 was $18.3 million, which was an increase of $1.7 million from the third quarter of 2012. No noncash, before-tax, other-than-temporary impairment charges were recognized during the third quarter of 2013. Included in noninterest income for the third quarter of 2012 were noncash, before-tax, other-than-temporary impairment charges of $2.3 million on certain investment securities. Excluding the results of the noncash, other-than-temporary impairment charges as well as net gains and losses from sales and calls of investment securities, noninterest income for the third quarter of 2013 decreased $588 thousand or 3% from the third quarter of 2012. This decrease for the third quarter of 2013 was due primarily to small decreases in several noninterest income items, none of which were individually significant.

Noninterest income for the first nine months of 2013 was $55.8 million, which was an increase of $6.2 million from the first nine months of 2012. Included in noninterest income for the first nine months of 2013 were noncash, before-tax, other-than-temporary impairment charges of $971 thousand on certain investment securities as compared to noncash, before-tax other-than-temporary impairment charges of $5.4 million on certain investment securities for the first nine months of 2012. Excluding the results of the noncash, other-than-temporary impairment charges as well as net gains and losses from sales and calls of investment securities, noninterest income for the first nine months of 2013 increased $1.4 million or 3% from the first nine months of 2012. This increase for the first nine months of 2013 was due primarily to increases of $921 thousand in income from bank-owned life insurance policies due to a death benefit, $689 thousand in mortgage banking income due to increased sales of mortgage loans in the secondary market and $448 thousand in fees from bankcard services due to increased volume. Partially offsetting these increases was a decrease of $1.1 million in fees from deposit services due to lower overdraft fee income.

On a linked-quarter basis, noninterest income for the third quarter of 2013 decreased $764 thousand or 4% from the second quarter of 2013. This decrease for the third quarter of 2013 was due primarily to decreases of $364 thousand in income from trust and brokerage services due to a decrease in volume and the value of assets under management and $285 thousand in income from derivatives not in hedge relationships due to a change in the fair value. No significant noncash, other-than-temporary impairment charges or net gains from sales and calls of investment securities were included in the results for the third quarter and second quarter of 2013.

Noninterest expense for the third quarter of 2013 was $48.6 million, a decrease of $5.3 million or 10% from the third quarter of 2012. Included in the results for the third quarter of 2012 was the previously mentioned litigation settlement accrual of $3.3 million. In addition, data processing expense declined $795 thousand due to a change in servicers and other real estate owned (OREO) expense decreased $625 thousand as reductions to fair value declined.

Noninterest expense for the first nine months of 2013 was $145.4 million, a decrease of $10.0 million or 6% from the first nine months of 2012. Included in the results for the first nine months of 2012 was the litigation settlement accrual of $3.3 million. Otherwise, employee compensation for the first nine months of 2013 declined $2.3 million due to a reduction in employees from a merger of banking subsidiaries in 2012. In addition, other real estate owned (OREO) expense decreased $1.5 million as reductions to fair value and losses

on sales declined, data processing expense declined $1.1 million due to a change in servicers, equipment expense decreased $1.0 million due mainly to a decline in maintenance costs from the first nine months of 2012. Partially offsetting these decreases was an increase of $1.2 million in employee benefits expense due mainly to higher pension costs. Also included in noninterest expense for the first nine months of 2013 was an increase in merger expenses of $805 thousand.

On a linked-quarter basis, noninterest expense for the third quarter of 2013 was flat from the second quarter of 2013, increasing $38 thousand or less than 1%. This slight increase was due primarily to increases of $312 thousand and $249 thousand in employee compensation and equipment expense, respectively. In addition, merger expenses increased $187 thousand from the second quarter of 2013. Virtually offsetting these increases was a decline of $795 thousand in other real estate owned (OREO) expense as reductions to fair value declined.

During the third quarter of 2013, United’s Board of Directors declared a cash dividend of $0.31 per share. United has increased its dividend to shareholders for 39 consecutive years. The annualized 2013 dividend of $1.24 equates to a yield above 4% based on recent UBSI market prices.

Use of non-GAAP Financial Measures

This press release contains certain financial measures that are not recognized under U.S. generally accepted accounting principles (“GAAP”). Generally, United has presented these “non-GAAP” financial measures because it believes that these measures provide meaningful additional information to assist in the evaluation of United’s results of operations or financial position. Presentation of these non-GAAP financial measures is consistent with how United’s management evaluates its performance internally and these non-GAAP financial measures are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in the banking industry.

Specifically, this press release contains certain references to financial measures identified as tax-equivalent (FTE) net interest income, noninterest income excluding the results of the noncash, other-than-temporary impairment charges as well as net gains and losses from sales and calls of investment securities, tangible equity and tangible book value per share. Management believes these non-GAAP financial measures to be helpful in understanding United’s results of operations or financial position.

Net interest income is presented in this press release on a tax-equivalent basis. The tax-equivalent basis adjusts for the tax-favored status of income from certain loans and investments. Although this is a non-GAAP measure, United’s management believes this measure is more widely used within the financial services industry and provides better comparability of net interest income arising from taxable and tax-exempt sources. United uses this measure to monitor net interest income performance and to manage its balance sheet composition. The tax-equivalent adjustment combines amounts of interest income on federally nontaxable loans and investment securities using the statutory federal income tax rate of 35%.

GAAP total non-interest income results are adjusted for other-than-temporary impairment charges (OTTI) on certain investment securities and net gains or losses on the sale of securities. Management believes noninterest income without OTTI charges and net securities gains or losses is more indicative of United’s performance because it isolates income that is primarily customer relationship driven and is more indicative of normalized operations. In addition, these items can fluctuate greatly from quarter to quarter and are difficult to predict.

Tangible common equity is calculated as GAAP total shareholders’ equity minus total intangible assets. Tangible common equity can thus be considered the most conservative valuation of the company. Tangible common equity is also presented on a per common share basis. Management provides these amounts to facilitate the understanding of as well as to assess the quality and composition of United’s capital structure. By removing the effect of intangible assets that result from merger and acquisition activity, the “permanent” items of common equity are presented. These two measures, along with others, are used by management to analyze capital adequacy.

Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as reconciliation to that comparable GAAP financial measure can be found in the attached financial information tables to this press release. Investors should recognize that United’s presentation of these non-GAAP financial measures might not be comparable to similarly titled measures at other companies. These non-GAAP financial measures should not be considered a substitute for GAAP basis measures and United strongly encourages a review of its condensed consolidated financial statements in their entirety.

Forward-Looking Statements

This press release contains certain forward-looking statements, including certain plans, expectations, goals and projections, which are subject to numerous assumptions, risks and uncertainties. Actual results could differ materially from those contained in or implied by such statements for a variety of factors including: changes in economic conditions; movements in interest rates; competitive pressures on product pricing and services; success and timing of business strategies; the nature and extent of governmental actions and reforms; and rapidly changing technology and evolving banking industry standards.
