PRESS RELEASE

Subject: United Bancorp, Inc. Reports Earnings of $2.398 Million for the Year Ended December 31, 2012

MARTINS FERRY, OHIO ¿¿¿ United Bancorp, Inc. (NASDAQ: UBCP), headquartered in Martins Ferry, Ohio reported net income of $2,398,000 for the year ended December 31, 2012 compared to $3,091,000 for the year ended December 31, 2011. On a per share basis, the Company’s diluted earnings were down 22.58% at $0.48 for the year ended December 31, 2012 as compared to $0.62 for the year ended December 31, 2011.

Randall M. Greenwood, Senior Vice President, CFO and Treasurer remarked, “The Company’s net income realized in 2012 generated an annualized 0.55% return on average assets (“ROA”) and a 6.74% return on average equity (“ROE”) compared to 0.73% ROA and 8.53% ROE for 2011. Comparing the year ended 2012 to 2011, the Company’s net interest margin was 3.89% compared to 4.18%, a decrease of 29 basis points. This decrease in the margin resulted in a $903,000 drop in net interest income which was primarily driven by shrinkage in the company’s investment portfolio. Implementation of the government mandated regulations from the Dodd-Frank Act regarding our Courtesy Overdraft Program caused a reduction in customer service fees of approximately $134,000. This was offset by an increase in other service fees which resulted in a net reduction of $42,000 in service fee income for the year ended December 31, 2012. During this current period, the Company did not have the substantial gains that it had in 2011 resulting from receiving a $100,000 BOLI benefit in excess of its surrender value and by recognizing a gain on sale of securities of $370,000 through liquidating its government sponsored mortgage-backed securities portfolio to take advantage of the favorable rate environment on these short term investments. The Company’s 2012 earnings were positively impacted by a period over period decrease of $840,000 in its provision for loan losses. This decrease in the provision for loan losses is directly attributed to the overall improvement in the credit quality of the loan portfolio. Net loans of $1,341,000 were charged off during 2012, a decrease of $445,000 or 24.9% from 2011. During 2012, a single out of area loan relationship accounted for $1,032,000 of the net loan amount charged off. Excluding this individual loan loss, the net loan amounts charged off during 2012 were $309,000. Other real estate owned decreased $236,000 or 11.6% from December 31, 2011 to December 31, 2012 and nonaccrual loans to total loans decreased by 61 basis points or $1,595,000, going from 1.71% in 2011 to 1.10%. These improving trends relating to credit quality are very positive considering that the present level of nonaccrual loans to total loans is nearly half of that of our peer group. Another area trending in a positive direction is core funding. Total deposits increased $21.9 million from December 31, 2011 to December 31, 2012 with most of this growth occurring in low cost funding. As a result of the booming activity of the oil and gas industry within our market areas, the Company has experienced a higher than normal influx of funds. Some of these funds may be temporary in nature and it is projected that a portion of these funds will flow back out of the Company within the next three to six months. These deposit fluctuations are closely monitored and are incorporated into our monthly asset/liability and funds management strategy. Also, in order to capitalize on its opportunities, the Company has implemented a marketing strategy in June 2012 focusing on attracting a larger percentage of low cost funding at each of its banking locations, while continuing to allow higher cost term funding to flow out. This will help lower the cost of funding in future periods. The Company has a significant present liquid position in cash-type investments which can be leveraged in future periods at higher yields when market conditions improve. Each of these opportunities has the potential to lead to higher levels of profitability.”

James W. Everson, Chairman, President & CEO stated, “During this time of economic uncertainty, we continue to pursue a conservative posture in managing our assets and liabilities. Our current short term objective is to cover our overhead, maintain our generous dividend payment which has a current yield of 4.4% and earn a limited return to our equity accounts until we see better opportunities to make sound investments without taking on excessive market risk due to the present interest rate environment being driven by the monetary policy of the Federal Reserve. Not wanting to take undue interest rate risk, we are keeping a higher level of liquidity in short term low yielding funds as Cash and due from the Federal Reserve Bank which has increased during the past twelve months 379% to $75.1 million. The 25 basis point return that we are presently receiving on these funds on the short term is having a limiting effect on our earnings. At present we believe it is imprudent to stretch investment maturities for higher yields. As an alternative, we continue to aggressively yet selectively make loans in the markets that we serve and continue to see this to be our only prudent and viable opportunity to generate an acceptable yield on our funds without adding to the risk position of our company. We are pleased to report that gross loans are up $12.0 million or 4.2%, year over year with continued improvement in the credit quality of our loan portfolio. The recent trend of exceptionally strong loan growth during the fourth quarter of 2012 is highly encouraging and it is anticipated that this positive trend will continue in the coming year with the additional resources that we have dedicated to our lending function this past year.” Everson concluded, “Community banking is under siege by current monetary policies and regulations which have the potential to shrink the number of banks in our country. We firmly believe that a community banking company as ours with strong and conservative practices will be positioned to weather this present storm and will be in a very sound position in future periods to grow and prosper. This structural soundness could lead to positive growth opportunities. Our company is blessed with a strong and talented management group that is poised for succession, a strong capital base and financial statement, the latest in high tech and efficient operating systems and a geographically diverse spread of twenty modern office locations over four distinct economic areas within Ohio. We take great pride in the fact that we are a strongly compliant SEC Registrant that is publically traded on the NASDAQ. Today, although we may be suffering a little ‘short term pain for long term gain’, our long term goal is to be a strong and profitable survivor in this presently changing banking environment and to reward our owners with solid growth in their shareholder value.”
