United Bancorp, Inc. Reports Record Earnings for Both the Fourth Quarter and Year Ending December 31, 2020

MARTINS FERRY, OHIO ◆◆◆ United Bancorp, Inc. (NASDAQ: UBCP) reported diluted earnings per share of $1.39 and net income of $7,953,000 for the twelve months ended December 31, 2020, as compared to its previous record levels of $1.19 and $6,810,000, respectively, for the corresponding twelve-month period in 2019. The Company’s diluted earnings per share for the three months ended December 31, 2020 was $0.46, as compared to $0.31 for the same period in the previous year, an increase of 48.4%. Even though the Company achieved record earnings in 2020, overall earnings were negatively affected by a higher provision for loan losses and other expenses or revenue losses that it realized due to the impact of the COVID-19 pandemic that ravaged our national economy and country this past year.

Randall M. Greenwood, Senior Vice President, CFO and Treasurer remarked, “In light of the events that have had a significant impact on our Company and economy as a whole this past year, we are extremely pleased to report on our record earnings performance for both the most recently ended quarter and the twelve months ended December 31, 2020. For the fourth quarter of 2020, our Company achieved net income of $2,640,000 and diluted earnings per share of $0.46, which was a respective increase for each of $872,000 and $0.15, or 48.4%, over the previous year. For the twelve months ending December 31, 2020, our Company had net income of $7,953,000 and diluted earnings per share of $1.39 versus $6,810,000 and $1.19 respectively for the preceding year, an increase for both of 16.8% — even though we booked an additional $2,429,000 in loan loss provision during the current year, raising the level of our total allowance for loan losses to total loans from 0.51% to 1.15% as of year-end. Contributing to our achievement of a sound level of earnings this past year was the solid growth that our Company experienced in its earning assets. Year-over-year, average loans increased by $25.8 million, or 6.1%, and average securities and other required stock increased by $9.8 million or 6.2%. Even with the FOMC implementing its Zero Interest Rate Policy (ZIRP) early in 2020 due to the COVID-19 pandemic, our solid growth in our earning assets, along with our robust loan fee generation (which increased by $575,000, or 61%, year-over-year), led to an increase of $594,000 in our level of total interest income realized — an improvement of 2.2% over the previous year. As we have formerly disclosed, our Company prudently started to position its balance sheet to be more liability sensitive early in the second quarter of 2019 in response to the FOMC’s change in the direction of monetary policy at that time. This action put us in a more strategic position to fully benefit from the ZIRP implemented almost overnight by the FOMC in the first quarter of 2020 when the potential effects of the COVID-19 pandemic on our country and economy were more fully understood. Being in a very good position from a sensitivity perspective when this sudden and drastic change in monetary policy occurred, our Company saw its total interest expense decrease in 2020 from the previous year by $1,390,000 or 22.7% — a level which helped us lower our overall total interest expense on a year-over-year basis for the first time in several years as we had

properly and responsively prepared for the downward trending rate environment in which we presently operate and foresee operating within for an extended period. With our focus on both growing earning assets and aggressively managing our sensitivity, our Company saw a year-over-year increase in its net interest income of $1,984,000 or 9.5%. As of December 31, 2020, our Company’s net interest margin was 3.76%, which is an increase of nine basis points year-over-year and compares very favorably to our peer. Obviously, if rates stay lower for longer as the FOMC has communicated, this could challenge us to maintain our net interest margin at its present level.”

Greenwood continued, “Even though we fully realize that the continuing pandemic situation has the potential to change our qualitative metrics relating to credit, we have successfully maintained overall strength and stability within our loan portfolio throughout the course of this past year and at year-end. As of December 31, 2020, our Company continues to have very solid credit quality-related metrics supported by a relatively low level of nonaccrual loans and loans past due 30 plus days, which were $832,000, or 0.19% of total loans, versus $2,660,000 and 0.60%, respectively, the previous year. Further, net loans charged off, excluding overdrafts, was $378,000, or 0.08% annualized. With our increased provision for loan losses this past year, our total allowance for loan losses more than doubled year-over-year and our total allowance for loan losses to nonaccrual loans was 816.4% at year-end. We remain committed — as we were throughout the entire year of 2020 — to closely working with our valued loan customers to keep their loans current by following payment relief practices fully supported by both regulatory and accounting guidance. We are hopeful that these positive actions will allow our customers who are still being negatively impacted by the pandemic to weather the storm and our Company to maintain its present state of sound credit quality. Over the course of this most recently ended quarter, we were encouraged to see most of our loan customer base that had previously received some level of payment relief in 2020 make either contractual or interest only payments on their loans. We are hopeful that this current trend will continue; but, being realistic, we firmly recognize that our credit quality metrics could deteriorate if our economy does not normalize in the near term.” Greenwood further stated, “Our Company continues to have very sound levels of capital. As previously announced in the second quarter of 2019, we enhanced our capital levels by issuing $20.0 million in subordinated debt at very favorable terms. Even though this capital is only measured at the bank-level, it has provided some very welcome cushion during these very challenging times. Overall, our Company saw shareholders’ equity grow by $8.4 million, or 14.0%, and its book value increase by $1.21, or 11.8%, year-over-year.”

Scott A. Everson, President and CEO stated, “As our Company navigated through an unprecedented and highly uncertain operating environment in 2020, I am extremely proud to report that we responded well to the challenges with which we were confronted and produced record earnings. We are exceptionally grateful for the level of increased earnings that we achieved in the pandemic-challenged economy in which we operated this past year and continue to be both mindful and respectful of the continuing challenges that it will pose for our Company in the current year. Accordingly, we continue to posture our Company for a longer duration downturn due to the negative macroeconomic forces with which we continue to be confronted related to the impacts of the pandemic on both our domestic and world economies. But, with the recent development of a COVID-19 vaccine and our solid credit related metrics and loss coverage related thereto, our Company did not contribute an additional provision to our relatively robust loan loss reserve this past quarter. Giving consideration to our exceptionally strong coverage ratio at year-end, we may be able to continue this course in the coming year if our credit metrics remain solid and the economy continues to improve and get closer to pre-pandemic performance levels.” Everson continued, “We are comforted to know that our Company continues to be well capitalized under regulatory and industry guidelines, which should help us weather any storm that may confront us. In addition, our Company has always had a long-term view, predicated on sound underwriting practices, superior customer service and prudent liquidity and capital management, which has served us well through various operating environments. We are confident that this philosophy will again prove to be sound as we support our customers and work through this present crisis; therefore, protecting our shareholder value.”

Everson concluded, “This past year was extremely trying for our nation and our thoughts and prayers continue to go out to everyone as we all work through the challenges presented to us by this horrible COVID-19 pandemic. Our number one priority continues to be protecting the health and welfare of our team members and customer base, while delivering the highest quality service possible under the circumstances.

During this time of great uncertainty, we are blessed to have both systems and personnel capable of delivering quality service and support to our valued customers. From an operating perspective, our Company was back to full operations and availability for the entire second half of 2020. In addition, I am extremely happy to report that we opened our newest Banking Center in Moundsville, West Virginia during this timeframe. This new location, our Company’s twentieth full-service Banking Center, is our first one located in the State of West Virginia. Although we are open to the public, we are taking extreme precautions in our operations by following the strict and further evolving guidance provided by both governmental and health authorities. We are truly blessed to have an extremely caring and resilient team of employees that helped our Company perform at a record level during arguably the most demanding environment in which any of us have ever worked. It is only through the diligence of our team members that we have been able to execute at a high level and achieve the record level of earnings that we did in 2020. For this, our team is to be commended and, as always, I am exceptionally proud of their willingness to overcome extreme obstacles, their ability to produce stellar results under trying circumstances and, in general, their overall fortitude… our Company is truly blessed to have such a motivated and Unified Team!”
