FOR IMMEDIATE RELEASE: 1:00 PM October 21, 2011

Subject: United Bancorp, Inc. Reports a 12.7% increase in Earnings for the Three Months Ended September 30, 2011

MARTINS FERRY, OHIO ¿¿¿ United Bancorp, Inc. (NASDAQ: UBCP), headquartered in Martins Ferry, Ohio reported net earnings for the three months ended September 30, 2011 of $801,056, compared to $710,956 for the three months ended September 30, 2010, an increase of 12.7%. On a per share basis, the Company’s three months diluted earnings per share were $0.16 for 2011, as compared to $0.15 for 2010, an increase of 6.7%. For the nine months ended September 30, 2011, the Company reported $2,291,301 compared to $2,094,334, an increase of 9.4%. On a per share basis, the Company’s nine month diluted earnings per share were $0.46 for 2011, as compared to $0.43 for 2010, an increase of 7.0%.

Randall M. Greenwood, Senior Vice President, CFO and Treasurer remarked, “The Company’s earnings for the nine months ended September 30, 2011 generated an annualized 0.72% return on average assets (“ROA”) and a 8.39% return on average equity (“ROE”), compared to 0.69% ROA and 8.47% ROE for the nine months ended September 30, 2010. Comparing the nine months ended September 30, 2011 to 2010, the Company’s net interest margin was 4.25% compared to 3.94%, an increase of 31 basis points. This increase in the margin resulted in a $360,000 increase in net interest income for the nine months ended September 30, 2011 as compared to the same period in 2010. Comparing the same periods, Customer Service Fees on deposits decreased $144,000. As the Company continues to implement government imposed regulations from the Dodd-Frank Act regarding its courtesy overdraft program, we will continue to experience regulatory requirements that may result in a decrease in customer service fees. In anticipation of these challenges and their potential impact on non-interest income, a variety of cost savings initiatives have been implemented in 2011 to reduce the non-interest expense of the Company. Year-to-date non-interest expense (with certain exclusions) decreased by $189,000. The majority of the decrease in non-interest expense is due to the Company’s cost savings initiatives implemented during the second and third quarters of 2011. As we move forward, these cost saving initiatives will have a positive impact on earnings and help offset some of the anticipated decline in non-interest income. The Company recognized a gain on sale of securities of $370,000 for the nine months ended September 30, 2011 and the Company received $100,000 of a BOLI benefit in excess of surrender value. The securities gain was the result of the Company selling its government sponsored mortgage–backed securities portfolio to take advantage of the favorable rate environment on these short term investments and provide liquidity to restructure the Company’s balance sheet to shift towards higher yielding loan relationships. On the expense side, the Company’s 2011 earnings were affected by a period over period increase of $493,000 in our provision for loan losses. The increase in the provision for loan losses was predicated primarily upon the economic challenges facing the banking industry. While net loans charged off did increase for the nine months ended September 30, 2011 as compared to the same period in 2010, the Company was able to move those charged off credits through the collection process and into Other Real Estate for Sale and begin to market these properties for sale. This resulted in an increase in Other Real Estate and resulted in comparable decrease in Non-Accrual Loans. Nonaccrual Loans to Total Loans decreased by nearly 22 basis points, going from 1.75% in 2010 to 1.53% for the same period in 2011. A declining trend in this area is very positive and the present level of nonaccrual loans to total loans is nearly half of that of our peer group.”

James W. Everson, UBCP’s Chairman, President and CEO stated, “Our focus continues on improving asset quality and reducing operating expenses of our Company. We have reduced our non-performing loans by 12.2%, mostly through charge offs. To compensate for this, our provision for loan losses year over year is up 46.9% while posting this reported earnings increase. Our asset quality has stabilized as we continue to curtail our asset growth to maintain our regulatory “Well Capitalized” status. With the Federal Reserve’s present control on interest rates, it would be easy for us to over pay and add growth at the risk of earnings and capital adequacy. In addition, we are keenly focused on making our Company more operationally efficient by taking advantage of opportunities presented through the recent implementation of our new core operating technologies allowing several cost savings initiatives which will lead to continued cost savings going forward.” Everson concluded, “We continue to project Earnings per Share of $0.62 this year-end 2011, up 19.2% from last year’s $0.52 EPS.”
