FOR IMMEDIATE RELEASE:            11:00 a.m. October 9, 2018

United Bancorp, Inc. Reports a 33% Increase in Net Income for the Nine Months Ended September 30, 2018; Diluted Earnings per Share of $0.69 versus $0.55 Reported in 2017, and a Dividend Yield of 3.95%

MARTINS FERRY, OHIO ◆◆◆ United Bancorp, Inc. (NASDAQ: UBCP), headquartered in Martins Ferry, Ohio, reported diluted earnings per share of $0.69 and net income of $3,691,000 for the nine months ended September 30, 2018, as compared to $0.55 and $2,766,000, respectively, for 2017. The Company’s diluted earnings per share for the three months ended September 30, 2018, was $0.25 as compared to $0.20 for the same period in 2017. These year-over-year improvements in UBCP’s earnings are directly related to the lower base corporate tax rate resulting from the passage of the Tax Cuts and Jobs Act (“tax act”) in the fourth quarter of 2017 and the benefit of operational improvements on which the company is seeing a positive return. Each of these realities should benefit the company in future periods.

Randall M. Greenwood, Senior Vice President, CFO and Treasurer remarked, “We are excited to report on the solid performance that our Company had for the nine-month period ended September 30, 2018. Our Company had a solid increase in net income of $924,000, or 33.4%, for the nine months ended September 30, 2018, over the nine months ended September 30, 2017. On an operating basis, the primary drivers of this year-over-year increase in net income were the increases in interest income and fees on loans, which were up by $1.3 million, or 10.6%, and the interest income on securities, which was up by $875,000, or 145.1%. Relating to loan growth, our Company had an increase in its gross loans of $32.8 million, or 9.1%, from September 30, 2017 to September 30, 2018. While growing the loan portfolio, our Company was able to maintain its overall stability in credit quality. Year-over-year, we continued to have very solid credit quality-related metrics supported by low levels of nonaccrual loans of approximately $1.3 million at both September 30, 2018 and 2017. Further—net loans charged off, excluding overdrafts, was $238,000 for the nine months ended September 30, 2018, which is a relatively modest increase of $84,000 from the nine months ended September 30, 2017. Annualized net charge offs to average loans was 0.08% for the nine months ended September 30, 2018, as compared to 0.06% for the nine months ended September 30, 2017.” Greenwood continued, “Due to the rising rate environment in which we are currently operating, we are seeing opportunities in the area of investment securities. In this current rate environment, yields on select securities are at levels that we have not seen for several years, which are encouraging us to leverage-up to some degree. Since September 30, 2017, our Company saw an increase in securities and other restricted stock of $47.3 million, or 109.3%, from the prior year. With our quarter-ending securities and other restricted stock position of $90.6 million being above the quarterly average of $75.3 million (and, also, with our gross loans

being $17.2 million above the quarterly average for loans), we anticipate even further contribution from these key revenue generating areas to interest income in future periods. With the enhanced level of total interest income that we realized in the first nine months of 2018, net interest income for the nine months ended September 30, 2018 for our Company increased by $1.4 million, or 11.9%, even as we focused on growing retail core deposits to fund our growth. Total deposits increased by $53.5 million, or 14.0%, to a level of $434.3 million as of September 30, 2018. Even with this significant increase in total deposits, we were able to control our overall interest expense levels by attracting lower-cost retail funding to replace higher-cost wholesale funding advances that matured over the past 12 months. Overall, our Company saw low-cost retail funding (consisting of non-interest and interest bearing demand and savings deposits) comprise $33.8 million of its growth in retail deposits year-over-year. In addition, time deposits, which consist of certificate of deposit or term funding, increased by $19.6 million, or 30.0%, for the same period. Funding our present growth with increased levels of retail core deposits and overnight wholesale borrowings in an increasing interest rate environment led to a slight elevation in our interest expense levels year-over-year. Accordingly, our interest expense to average assets increased from 0.40% for the nine months ended September 30, 2017 to 0.58% for the nine months ended September 30, 2018. Even with this increase in our interest expense, we were able to grow our interest income to a greater degree and, thereby, increase our net interest margin. Year-over-year, our net interest margin improved to a level of 3.90% as of the end of this most recent quarter versus 3.80% for the same nine month period in 2017.”

Relating to our Company’s net noninterest margin, Greenwood stated, “Our total noninterest income increased $73,000, or 2.8%, year over year. Service charges on deposit accounts, which is the area in which our Company performs at a high level relative to peer, strongly contributed to this increase. On the noninterest expense-side of the net noninterest margin (and, as budgeted), we experienced an increase in our noninterest expense of $1.0 million or 10.1%. Most of the increase in noninterest expense continues to be related to infrastructure enhancement and personnel-related expenses to support the growth that our Company envisions for the future.” Greenwood concluded, “Considering that most of the aforementioned expenses are “fixed,” we firmly believe that we have positive operating leverage. This reality should allow us to drive higher levels of revenue without significantly adding to our overall noninterest expense levels in the short-term; thereby, further enhancing our Company’s earnings and returns. And, lastly, also significantly contributing to the increase in noninterest expense levels for the nine months ended September 30, 2018 are the approximately $223,000 in merger-related and other one time expenses that we have incurred during the current year. A majority of these expenses are relating to the June 14, 2018, announcement of our Definitive Agreement to acquire Powhatan Point Community Bancshares, Inc. These one-time expenses decreased the diluted earnings per share for our Company by $0.02 in the most recent quarter and $0.04 for the nine months ended September 30, 2018. It is anticipated during the fourth quarter of 2018 that we will incur additional merger-related expenses in connection with this transaction as we work toward a closing.”

Scott A. Everson, President and CEO stated, “We are extremely pleased to see the strong growth in our earnings for the nine months ended September 30, 2018. Our Company continues to benefit from the enactment of the tax act, which has reduced the overall tax rate for companies, such as ours, from 35% to 21%. We are also gratified to see that our investment in both the infrastructure and personnel of our Company is producing a positive return for us. On an operating basis, we saw an improvement in our earnings before taxes even though we had non-recurring expenses relating to our upcoming acquisition of Powhatan Point Community Bancshares, Inc. With our enhanced lending platforms, we anticipate seeing continued above peer loan growth in the coming quarters. In addition, with our continued focus on an investment strategy that was implemented during the first quarter of this year, we also anticipate having increasing levels of higher yielding investment securities on our balance sheet in the coming quarters. Each of these aforementioned items will continue to drive our organic growth and has led to year-over-year growth in earning assets (consisting of both loans and investment securities) of $80.1 million or 19.8%. This organic growth will be further enhanced with our upcoming merger, which should lead to the continuation of our Company growing its level of earning assets and generating higher levels of interest income. Even with this strong growth in both earning assets and core deposits, we have been able to expand our net interest margin and improve our overall level of net interest income. Year-over-year, we saw the net interest margin of our Company improve by ten (10) basis points to a level of 3.90% as of September 30, 2018. Our enhanced net interest margin led to our net interest income improving on a year-over-year basis by $1.4 million or 11.9%.”

Everson continued, “We have stated for many quarters that our goal is to profitably grow our Company. We are gratified that we are presently in a position to accomplish this. At this most recent quarter end, our Company had total assets of $525.3 million, which is an increase of $70.8 million, or 15.6%, over the previous year. With the level of organic growth that we have achieved on a year-over-year basis, our current level of total assets is the highest in our Company’s history. Our viewpoint is that profitable growth will lead to positive opportunities to further grow our Company! In this area, we have very high expectations over the course of the next three years. Our ultimate goal is to become a “hybrid or omnichannel” bank; whereby, we can serve our present and future customers on “their” terms. By having both exceptional “in-branch” and “virtual” service options for our customers, we believe that our Company will have relevance within our industry for many years to come. In addition, we will be able to deliver on our current vision for growth, which is to have total assets greater than $1.0 billion in order to gain greater operational efficiencies. As previously disclosed, our Company and Powhatan Point Community Bancshares, Inc. (PPCB), the holding company for First National Bank of Powhatan Point, announced on June 14, 2018 that we have signed a definitive merger agreement; whereby, we will acquire PPCB in a stock and cash transaction. It is anticipated, pending the approval of PPCB Shareholders, that this merger will be completed sometime during the current month. At that time, the main office of First National Bank will become a full-service branch of Unified Bank. This merger with PPCB and First National Bank will add approximately $60.7 million in assets, $6.7 million in loans, $55.4 million of deposits and $5.0 million in consolidated equity to our Company. In addition, this transaction will develop a presence for our Company in Southern Belmont County, which has seen nice growth in recent years relating to the oil and gas development in this area. This new market also has the potential for much more growth with the expected announcement of the building of a much anticipated ethane cracker plant. We look forward, with much anticipation, to welcoming Powhatan Point Community Bancshares to the United Bancorp Family!”

Everson concluded, “As always, one of our primary focuses is to reward our valued shareholders by paying a solid cash dividend. With our improving earnings in 2018, we increased our quarterly cash dividend payout level during the first quarter of this year. On a year-over-year basis as of September 30, 2018, our Company paid cash dividends of $0.39 versus $0.34 in 2017, an increase of 14.7%. At our present quarterly cash dividend payout level of $0.13, our Company’s stock has a forward dividend yield of 3.95%, which is significantly higher than the average cash dividend yield seen within our industry. Our other primary focus continues to be growing our shareholders’ investment in our Company through profitable operations and strategic growth. As of the most recent quarter end, our market value was $13.15, which is up from the same period in the previous year by $1.15 or 9.6%. We will continue to keenly focus on these two key areas to create additional value for our loyal shareholders. Overall, we are pleased with the improving performance of our Company during the first nine months of 2018 and the direction that we are going. With the positive growth that we have experienced so far in 2018, and with the anticipated growth that will occur during the remainder of the current year, we are extremely optimistic about our potential to further improve the earnings of our Company and look forward to realizing this upside potential in future periods!”
