United Bankshares, Inc. Announces Earnings

for the Third Quarter and First Nine Months of 2011

WASHINGTON, D.C. and CHARLESTON, WV — United Bankshares, Inc. (NASDAQ: UBSI), today reported earnings for the third quarter and the first nine months of 2011. Earnings for the third quarter of 2011 were $20.0 million or $0.40 per diluted share while earnings for the first nine months of 2011 were $55.4 million or $1.21 per diluted share.

Third quarter of 2011 results produced a return on average assets of 0.95% and a return on average equity of 8.26%, respectively. For the first nine months of 2011, United’s return on average assets was 0.98% while the return on average equity was 8.62%. These returns compare favorably to United’s most recently reported Federal Reserve peer group’s (bank holding companies with total assets between $3 and $10 billion) average return on assets of 0.72% and average return on equity of 6.56% for the first six months of 2011.

The results for the third quarter and first nine months of 2011 included before-tax, other-than-temporary impairment charges of $7.9 million and $14.1 million, respectively, on certain investment securities. In addition, on July 8, 2011, United completed its acquisition of Centra Financial Holdings, Inc. (Centra) of Morgantown, West Virginia. The results of operations of Centra are included in the consolidated results of operations from the date of acquisition. As a result, comparisons for the third quarter and first nine months of 2011 to the same time periods of 2010 are impacted by increased levels of average balances, income, expense, and asset quality results due to the acquisition. At consummation, Centra had assets of approximately $1.3 billion, loans of $1.0 billion, deposits of $1.1 billion and shareholders’ equity of $131 million.

Earnings for the third quarter of 2010 were $17.3 million or $0.40 per diluted share while earnings for the first nine months of 2010 were $52.7 million or $1.21 per diluted share. The results for the third quarter and first nine months of 2010 included before-tax, other-than-temporary impairment charges of $1.9 million and $4.4 million, respectively, on certain investment securities. United’s annualized returns on average assets and average equity were 0.91% and 8.73%, respectively, for the third quarter of 2010 while the returns on average assets and average equity was 0.93% and 9.04%, respectively, for the first nine months of 2010.

United’s asset quality also continues to outperform its peers. United’s percentage of nonperforming loans to loans, net of unearned income of 1.18% at September 30, 2011 compares favorably to the most recently reported percentage of 3.83% at June 30, 2011 for United’s Federal Reserve peer group. At September 30, 2011, nonperforming loans were $73.7 million as compared to nonperforming loans of $67.2 million or 1.28% of

loans, net of unearned income, at December 31, 2010. As of September 30, 2011, the allowance for loan losses was $73.5 million or 1.17% of loans, net of unearned income, as compared to $73.0 million or 1.39% of loans, net of unearned income, at December 31, 2010. United’s coverage ratio of its allowance for loan losses to nonperforming loans also compares favorably to its peers. The coverage ratio for United was 99.7% and 108.6% at September 30, 2011 and December 31, 2010, respectively. The coverage ratio for United’s Federal Reserve peer group was 83.6% at June 30, 2011. The declines in the ratios at September 30, 2011 of the allowance for loan losses as a percentage of loans, net of unearned income and of nonperforming loans was because United was unable to carry-over Centra’s previously established allowance for loan losses in accordance with accounting rules. United recorded a downward fair value adjustment of approximately $36.7 million on the loans acquired from Centra. Total nonperforming assets of $126.4 million, including OREO of $52.7 million at September 30, 2011, represented 1.47% of total assets which also compares favorably to the most recently reported percentage of 3.24% at June 30, 2011 for United’s Federal Reserve peer group.

United continues to be well-capitalized based upon regulatory guidelines. United’s estimated risk-based capital ratio is 13.6% at September 30, 2011 while its Tier I capital and leverage ratios are 12.4% and 10.4%, respectively. The regulatory requirements for a well-capitalized financial institution are a risk-based capital ratio of 10%, a Tier I capital ratio of 6% and a leverage ratio of 5%.

During the third quarter of 2011, United’s Board of Directors declared a cash dividend of $0.30 per share. United has increased its dividend to shareholders for 37 consecutive years. The annualized 2011 dividend of $1.20 equates to a yield of approximately 5% based on recent UBSI market prices.

“Considering the current economic environment, United’s earnings continue to be strong with asset quality favorable to peers,” 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.”

Tax-equivalent net interest income for the third quarter of 2011 was $72.5 million, an increase of $12.1 million or 20% from the third quarter of 2010. This increase in tax-equivalent net interest income was primarily attributable to an increase in average earning assets from the Centra acquisition. Average earning assets increased $770.9 million or 12% from the third quarter of 2010. Average net loans increased $777.0 million or 15% for the third quarter of 2011. In addition, the average cost of funds declined 55 basis points from the third quarter of 2010. Partially offsetting the increases to tax-equivalent net interest income for the third quarter of 2011 was a decline of 23 basis points in the average yield on earning assets for the third quarter of 2011 as compared to the same quarter in 2010. The net interest margin for the third quarter of 2011 was 3.87%, which was an increase of 27 basis points from a net interest margin of 3.60% for the third quarter of 2010.

Tax-equivalent net interest income for the first nine months of 2011 was $193.6 million, an increase of $9.5 million or 5% from the first nine months of 2010. This increase in tax-equivalent net interest income was primarily attributable to a decrease in average interest-bearing liabilities of $421.7 million or 7% due mainly to the net repayment of approximately $360 million in Federal Home Loan Bank advances since September 30, 2010. Average earning assets were relatively flat, decreasing $65.2 million or less than 1% from the first nine months of 2010. Average net loans were also flat, increasing $13.1 million or less than 1% for the first nine months of 2011 while average investments decreased $111.3 million or 12%. In addition, the average cost of funds declined 50 basis points from the first nine months of 2010. Partially offsetting the increases to tax-equivalent

net interest income for the first nine months of 2011 was a decline of 25 basis points in the average yield on earning assets for the first nine months of 2011 as compared to the first nine months of 2010. The net interest margin for the first nine months of 2011 was 3.87%, which was an increase of 22 basis points from a net interest margin of 3.65% for the first nine months of 2010.

On a linked-quarter basis, United’s tax-equivalent net interest income for the third quarter of 2011 increased $12.3 million or 20% from the second quarter of 2011 due mainly to an increase in average earning assets as a result of the Centra merger. Average earning assets increased $1.2 billion or 18% from the second quarter of 2011 as average investment securities and average net loans increased $45.7 million or 6% and $952.9 million or 19% for the quarter, respectively. In addition, the average cost of funds declined 18 basis points from the second quarter of 2011. Partially offsetting the increases to tax-equivalent net interest income for the third quarter of 2011 was a decrease of 10 basis points in the average yield on earning assets from the second quarter of 2011. The net interest margin of 3.87% for the third quarter of 2011 was an increase of 4 basis points from the net interest margin of 3.83% for the second quarter of 2011.

For the quarters ended September 30, 2011 and 2010, the provision for loan losses was $3.6 million and $6.1 million, respectively, while the provision for the first nine months of 2011 was $12.9 million as compared to $19.4 million for the first nine months of 2010. Net charge-offs were $3.3 million and $4.7 million for the third quarter of 2011 and 2010, respectively, as compared to $12.4 million and $16.6 million for the first nine months of 2011 and 2010. Annualized net charge-offs as a percentage of average loans were 0.21% and 0.27% for the third quarter and first nine months of 2011, respectively. United’s most recently reported Federal Reserve peer group’s net charge-offs to average loans percentage was 1.01% for the second quarter of 2011.

Noninterest income for the third quarter of 2011 was $11.0 million, which was a decrease of $4.7 million from the third quarter of 2010. Included in noninterest income for the third quarter of 2011 were before-tax, other-than-temporary impairment charges of $7.9 million on certain investment securities. Included in noninterest income for the third quarter of 2010 were before-tax, other-than-temporary impairment charges of $1.9 million on certain investment securities. Excluding the results of the other-than-temporary impairment charges as well as net gains and losses from sales and calls of investment securities, noninterest income would have increased $1.0 million or 6% from the third quarter of 2010. This increase for the third quarter of 2011 was due primarily to increases of $364 thousand in fees from deposit services and $262 thousand in income from bank-owned life insurance policies. These increases were primarily due to the Centra merger.

Noninterest income for the first nine months of 2011 was $39.0 million, which was a decrease of $9.9 million from the first nine months of 2010. Included in noninterest income for the first nine months of 2011 was a before-tax, net gain of $1.6 million on the sales and calls of investment securities and before-tax, other-than-temporary impairment charges of $14.1 million on certain investment securities. Included in noninterest income for the first nine months of 2010 was a before-tax, net gain of $2.0 million on the sale of investment securities and before-tax, other-than-temporary impairment charges of $4.4 million on certain investment securities. Excluding the results of the other-than-temporary impairment charges as well as the net gains from the sales and calls of investment securities, noninterest income would have been relatively flat, increasing $208 thousand or less than 1%. This slight increase for the first nine months of 2011 was due primarily to increases of $995 thousand in fees from deposit services and $452 thousand in income from bank-owned life insurance policies

due to the Centra merger. Partially offsetting these increases was a decrease of $1.1 million in income from derivatives not in hedge relationships due to a change in the fair value and a decrease of $738 thousand in fees from bankcard services due mainly to the sale of United’s merchant business in the fourth quarter of 2010. A similar amount of expense related to the change in the fair value of other derivative financial instruments as well as a reduction in bankcard processing costs as a result of the sale of United’s merchant business is included in other expense in the income statement.

On a linked-quarter basis, noninterest income for the third quarter of 2011 decreased $2.4 million from the second quarter of 2011. Included in the results for the third quarter and second quarter of 2011 were before-tax, other-than-temporary impairment charges of $7.9 million and $4.1 million, respectively. Excluding the results of the other-than-temporary impairment charges as well as net gains and losses from sales and calls of investment securities, noninterest income would have increased $1.7 million or 10% on a linked-quarter basis due primarily to increases of $554 thousand in fees from bankcard services, $316 thousand in income from bank-owned life insurance policies, $268 thousand in income from derivatives not in hedge relationships due to a change in the fair value, and $121 thousand in fees from deposit services. A similar amount of expense related to the change in the fair value of other derivative financial instruments is included in other expense in the income statement.

Noninterest expense for the third quarter of 2011 was $48.9 million, an increase of $5.0 million or 11% from the third quarter of 2010 due primarily to increases of $2.4 million in employee compensation, $864 thousand in net occupancy expenses, $713 thousand in equipment expenses and $347 thousand in data processing fees. These increases were due mainly to the additional employees, offices, equipment and data processing from the Centra merger.

Noninterest expense for the first nine months of 2011 was $134.0 million which was relatively flat from the first nine months of 2010, increasing $1.2 million or less than 1%. The slight increase was due mainly to increases of $2.5 million in employee compensation, $446 thousand in net occupancy expenses, $1.0 million in equipment expenses and $457 thousand in data processing fees. These increases were due mainly to the additional employees, offices, equipment and data processing from the Centra merger. Virtually offsetting these increases were decreases of $1.6 million in bankcard processing expense due mainly to the sale of United’s merchant business in the fourth quarter of 2010, $1.1 million in OREO costs due mainly to fewer declines in the fair value of OREO properties and $1.1 million in the expense from derivatives not in hedge relationships due to a change in the fair value. As previously mentioned, a similar amount of income related to the change in the fair value of other derivative financial instruments as well as a reduction in bankcard servicing fees as a result of the sale of United’s merchant business is included in other income in the income statement.

On a linked-quarter basis, noninterest expense for the third quarter of 2011 increased $7.2 million or 17% from the second quarter of 2011 due mainly to the Centra merger. Accordingly, most major categories of noninterest expense showed increases. In particular, employee compensation expense increased $2.0 million, employee benefits expense increased $230 thousand, net occupancy expense increased $911 thousand, equipment expense increased $771 thousand, core deposit amortization increased $506 thousand and data processing fees increased $189 thousand mainly the result of the Centra merger. In addition, OREO expense increased $896 thousand due to a decline in the fair values of OREO properties and expense from derivatives not in hedge relationships increased $268 thousand due to a change in the fair value.
