FOR IMMEDIATE RELEASE: 1:00 p.m. October 16, 2017

United Bancorp, Inc. Reports Diluted Earnings per Share of $0.20 for the Three Months Ended September 30, 2017, an 11.1% increase over 2016, and a TTM Cash Dividend Yield of 4.2%

MARTINS FERRY, OHIO ◆◆◆ United Bancorp, Inc. (NASDAQ: UBCP), headquartered in Martins Ferry, Ohio, reported diluted earnings per share of $0.55 and net income of $2,766,000 for the nine months ended September 30, 2017, as compared to $0.53 and $2,679,000 for the same period in 2016. The Company’s diluted earnings per share and net income for the three months ended September 30, 2017 was $0.20 and $1,000,000 as compared to $0.18 and $928,000 respectively for the prior year, an increase of 11.1%.

Randall M. Greenwood, Senior Vice President, CFO and Treasurer remarked, “We are happy to report on the increase of the net interest income of our Company for the nine months ended September 30, 2017. During this period, the Company’s net interest income increased by $688,000, or 6.2%, from the previous year. The primary driver of this increase of the Company’s net interest income was the increase in interest income on loans, which was up by $508,000, or 4.5%, year-over-year. The increase in the interest income that our Company realized is directly attributed to the focus that we had on enhancing our lending platform over the course of the past year. For the year, our Company had an increase in its average loans of $14.2 million or 4.1%. Our company was able to achieve this level of growth in its loans outstanding while maintaining its overall stability in credit quality. Year-over-year, the Company continued to have very solid credit quality-related metrics supported by nonaccrual loans and loans past due 30+ days decreasing from a level of $2.75 million to $2.67 million, a decline of $80,000. Further— net loans charged off, excluding overdrafts, was $154,000 through September 30, 2017, which is a decrease of $48,000 from the previous year. At this present level, total past due and nonaccrual loans to gross loans is a very solid 0.70%, versus 0.80% the prior year. In addition, net charge offs to average loans was 0.06% for the nine months ended September 30, 2017.” Greenwood continued, “The net interest income for our Company increased year-over-year even as we focused on growing retail core deposits to fund our loan growth. Total deposits increased by $52.7 million, or 16.1%, to a level of $380.9 million as of September 30, 2017. The Company was able to control its overall interest expense levels by attracting lower-cost funding alternatives. Overall, the Company saw low-cost retail funding (consisting of non-interest and interest bearing demand and savings deposits) comprise $41.2 million of its growth in retail deposits year-over-year. In addition, the Company’s time deposits, which consist of certificate of deposit or term funding, increased by $11.6 million for the same period. Even with the above-peer growth in retail core deposit funding, the Company had a decrease in its overall interest expense to average assets, which decreased on a year-over-year basis from 0.43% to

0.40%. This decrease in the overall cost of funding is directly attributed to the repricing of $15.0 million of the Company’s fixed rate advances from the Federal Home Loan Bank (FHLB). The Company forecasts additional reductions in the cost of its present wholesale funding, which consists of an additional $5.0 million fixed rate advance with the FHLB, in the fourth quarter. By year-end, this FHLB advance (which presently costs the Company 3.08%) will be paid off with the current liquidity the company has on its balance sheet. By paying off this fixed rate advance with lower cost retail-based funding, the Company should realize additional savings or containment in its overall interest expense levels.”

Relating to the Company’s net noninterest margin, Greenwood stated, “the noninterest income of the Company was down by $233,000 year-over-year. The majority of this decrease in noninterest income is related to a $162,000 non-recurring gain that the Company realized on the sale of Bankers Bancshares, Inc. stock during 2016. On the noninterest expense-side of the net noninterest margin (and, as budgeted), the Company saw an increase in its overall noninterest expense levels after several years of decline. The Company saw its noninterest expense increase by $428,000 or 4.4%. Most of the increase in our noninterest expense was related to personnel-related expenses on the production-side and expenses related to our expansion into the Wheeling, West Virginia market with our new Loan Production Office, which should lead to our Company realizing higher levels of revenue as we have begun to see in the most recently completed quarter. Considering that most of this expense is “fixed,” we firmly believe that we should be able to drive higher levels of revenue without significantly adding to our overall noninterest expense levels in the short-term; therefore, enhancing our Company’s earnings and returns.”

Scott A. Everson, President and CEO stated, “We are pleased to report that we are executing upon our growth strategy, Mission 2020, which calls for our Company to grow its assets (in a profitable fashion) to a level of $1.0 billion or greater by the end of 2020. Even though we realize that we have an extremely long way to go in order to achieve our ambitious growth goal, it is gratifying to see the organic growth that we achieved year-over-year. Although we will need to have a compounded annual growth rate of approximately twenty-three percent from the beginning of this year to achieve the level of growth envisioned under Mission 2020, we firmly believe that it is achievable with the present vision that we have (which includes both organic and acquisition-related growth). From an organic perspective this past year, our Company grew its assets $29.0 million, or 6.8%, to an overall level of $455.0 million as of September 30, 2017. As previously mentioned, most of this growth in assets occurred in our Company’s higher-yielding loan portfolio, which enhanced the overall interest income that we realized. As previously mentioned, the overall net interest income realized by our Company increased year-over-year. Our Company was able to achieve this increase in net interest income by growing both its loans outstanding and core deposit funding.” Everson continued, “As expected, we saw marginal growth in the net income that our Company produced in the first two quarters of this year and we are extremely pleased to see that our earnings growth level is back to double digits on a percentage basis in the third quarter. After several years of containment, our Company saw its overall noninterest expense levels increase this past year as we continue to build for the future and support our overall mission for growth. Most of the increase in our noninterest expense levels occurred in the following areas: hiring additional loan origination personnel to drive the revenue of our Company; completing the renovation of our Main Office to support an enhanced loan origination platform; reorganizing and enhancing our Information Technology function to better manage risk and serve our valued customers; opening a new Loan Production Office in the Wheeling, West Virginia market to increase overall loan production and to introduce our Company to a new, highly desirable market; marketing expense relating to the prime retail deposit pricing that we have been successfully promoting; and, lastly, legal and other expenses related to the renaming of our Company’s single bank charter. Regarding the renaming of our single bank charter and as previously announced in the third quarter, The Citizens Savings Bank and its two divisions— The Citizens Bank and The Community Bank— were renamed to Unified Bank, which became effective on October 10, 2017. Renaming our bank-level charter, Unified Bank, will allow us to establish a more effective brand and better support our envisioned growth objective.” Everson

concluded by stating, “We firmly believe with our positioning over the course of the past year, our Company has high operating leverage which should allow us to enhance our revenue, while controlling our noninterest expense levels— thus, leading to higher earnings and returns over the course of the next twelve to eighteen months. We continue to have very solid credit quality metrics, which should have a positive impact on our earnings for the foreseeable future. In addition, we continue to have very robust capital levels, as evidenced by our overall equity to asset ratio of 9.71%, which will support our vision for growth in the intermediate term. Our Company continues to pay a very solid cash dividend, which totals $0.50 on a trailing twelve month (TTM) basis (including the $0.05 special dividend paid this past December), which produces at TTM Yield of 4.2% as of quarter-end. At this level, our Company’s cash dividend yield is significantly higher than that of the average bank in our country. With our recent focus of increasing the operating leverage and revenue of our Company, we firmly believe that we will continue to generate higher levels of net income and reward our shareholders by paying higher dividends and having further appreciation in our market value.” Everson concluded, “Our number one focus continues to be growing our shareholders’ investment in our Company through profitable operations and strategic growth. In addition to driving the market value appreciation of our shareholders’ ownership, we will continue striving to reward our owners by paying a solid cash dividend. Overall, we are pleased with the performance of our Company and the direction that we are going. We are extremely optimistic about our future potential and look forward to realizing this upside potential in future periods!”
