NEWS RELEASE

RIVERVIEW FINANCIAL CORPORATION

REPORTS FOURTH QUARTER AND ANNUAL EARNINGS FOR 2019

HARRISBURG, PA, January 31, 2020 / PRNEWSWIRE / Riverview Financial Corporation (the “Company” or “Riverview”) (NASDAQ: RIVE), today reported unaudited financial results at and for the three months and year ended December 31, 2019. Riverview reported net income of $1.3 million, or $0.14 per basic and diluted weighted average common share, for the fourth quarter of 2019, compared to net income of $2.5 million, or $0.27 per basic and diluted weighted average common share, for the fourth quarter of 2018. The decrease in results was caused primarily by recognizing $704 thousand less of net accretion on acquired assets and assumed liabilities along with lower average loan volumes comparing the fourth quarters of 2019 and 2018.

For the year ended December 31, 2019, Riverview reported net income of $4.3 million, or $0.47 per basic and diluted weighted average common share, compared to net income of $10.9 million, or $1.19 per basic and diluted weighted average common share, for the year ended December 31, 2018. The year over year reduction was largely a function of recognizing $1.7 million less of net accretion on acquired assets and assumed liabilities, a $2.2 million nonrecurring executive separation charge and $694 thousand of severance expense to employees that either retired or were separated from service due to branch network consolidations. The reduction in net income was also impacted by recording a loan loss provision of $2.4 million in 2019 compared to $615 thousand in 2018.

In addition to evaluating its results of operations in accordance with accounting principles generally accepted in the United States of America (“GAAP”), Riverview routinely supplements its evaluation with an analysis of certain non-GAAP financial measures, such as tangible book value per share and return on average tangible stockholders’ equity. Riverview believes these non-GAAP financial measures provide information useful to investors in understanding its operating performance and trends. Where non-GAAP disclosures are used in this press release, a reconciliation to the comparable GAAP measures is provided in the accompanying tables. The non-GAAP financial measures Riverview uses may differ from the non-GAAP financial measures other financial institutions use to measure their results of operations.

HIGHLIGHTS

“2019 operating results include large, nonrecurring expense items associated with strategic efficiency initiatives that are intended to positively impact earnings in future years,” said Brett D. Fulk, President and Chief Executive Officer, “including costs associated with the closure of three offices and the sale of a fourth office during the fourth quarter.” Fulk continued “2019 is a year we strategically chose to address unacceptable operating efficiency results, and will serve as a pivotal year in establishing a more efficient organization in the future. While we are keenly focused on improved efficiencies, it is also critically important for us to continue investing in new growth locations and in asset generation employees, which temporarily offsets the positive impacts taking hold as a result of our efficiency initiatives until these growth efforts result in new asset generation, which is beginning to occur as anticipated.”

Regarding asset generation, Fulk commented “as I stated in our third quarter earnings press release, it remains imperative we expand our earning asset base responsibly. The lack of organic loan balance growth during 2019 is being addressed by focusing on methods to generate additional opportunities without increasing our risk profile. Some of these methods include expansion into new growth markets through the opening of new full service offices and limited purpose offices, as well as attracting additional asset generation employees to our organization. We are experiencing strong loan demand within our expanded markets and through new employees focused on commercial relationship opportunities, and with a healthy pipeline of activity entering 2020 we expect to begin demonstrating growth in our loan balances outstanding early in the year.”

INCOME STATEMENT REVIEW

Tax-equivalent net interest income for the three months ended December 31 was $9.3 million in 2019 compared to $11.4 million in 2018. The decline in tax-equivalent net interest income was attributable to recognizing a lower amount of net accretion on purchased assets and assumed liabilities along with a reduction in average loan volumes. For the three months ended December 31, the tax-equivalent net interest margin decreased to 3.74% in 2019 from 4.30% in 2018. Excluding purchase accounting adjustments of $445 thousand in the fourth quarter of 2019 and $1,149 thousand in the fourth quarter of 2018, the tax-equivalent net interest margins were 3.56% in 2019 and 3.86% in 2018. The loan portfolio yield on a tax-equivalent basis declined to 4.86% in the fourth quarter of 2019 compared to 5.51% for the same period last year. Excluding loan accretion of $377 in the fourth quarter of 2019 and $1,437 in the fourth quarter of 2018, the tax-equivalent loan yield would have been 4.69% in 2019 and 4.88% in 2018. The cost of funds decreased 3 basis points comparing the fourth quarters of 2019 and 2018. Average loan volume declined $48.2 million to $859.9 million from $908.1 million comparing the three months ended December 31, 2019 and 2018.

For the year ended December 31, tax-equivalent net interest income declined $3.0 million to $41.2 million in 2019 from $44.2 million in 2018. The decrease in tax-equivalent net interest income was attributable to declines in average loan balances and reductions in net accretion on purchased assets and assumed liabilities. Loans averaged $879.3 million for the year ended December 31, 2019 compared to $928.5 million during 2018. For the year ended December 31, tax-equivalent net interest margin was 4.07% in 2019 compared to 4.19% in 2018. Adjusting for the recognition of purchase accounting adjustments of $3.5 million and $5.2 million, the tax-equivalent net interest margin would have been 3.72% and 3.70% for the years ended December 31, 2019 and 2018. The tax-equivalent yield on earnings assets was 4.91% and the cost of interest-bearing funds was 1.04% in 2019. The tax-equivalent yield on the loan portfolio decreased slightly to 5.24% in 2019 compared to 5.27% in 2018. Excluding loan accretion of $3.2 million and $5.2 million included in loan interest income related to acquired loans, the

tax-equivalent yield on the loan portfolio would have been 4.87% and 4.71% for the years ended December 31, 2019 and 2018. For the twelve months ended December 31, investments yielded 2.99% on a tax-equivalent basis in 2019 compared to 2.84% for the same period last year. The cost of deposits increased 15 basis points to 0.99% in 2019 from 0.84% in 2018. Excluding the impact of purchase accounting, the cost of deposits would have increased 13 basis points to 1.03% in 2019 from 0.90% in 2018. The cost of interest-bearing liabilities increased to 1.04% in 2019 from 0.91% in 2018. Excluding the impact of purchase accounting, the cost of interest-bearing liabilities would have increased 15 basis points in 2019.

For the quarter ended December 31, the provision for loan losses was $156 thousand in 2019 compared to no provision for the same period in 2018. The provision for loan losses totaled $2,406 thousand for the year ended December 31, 2019, compared to $615 thousand in 2018. The increase in the provision for loan losses in 2019 was caused by higher net charge-offs primarily associated with legacy purchased loans.

For the quarter ended December 31, noninterest income totaled $2,617 thousand in 2019, an increase of $277 thousand from $2,340 thousand in 2018. The increase in noninterest income for the quarter was due primarily to increases in services charges, fees and commissions of $138 thousand and mortgage banking income of $96 thousand and recognizing net gains on the sale of investment securities of $73 thousand. For the year ended December 31, noninterest income decreased to $8,514 thousand in 2019 compared to $8,880 thousand in 2018. The decrease was primarily a result of lower service charges, fees and commissions of $511 thousand and mortgage banking income of $74 thousand offset partially by increases in trust commissions and fees of $165 thousand and wealth management income of $129 thousand.

Noninterest expense decreased $451 thousand to $10,189 thousand for the three months ended December 31, 2019, from $10,640 thousand for the same period last year. The decrease in noninterest expense for the quarter was due primarily to decreases in salaries and employee benefits expense of $1,216 thousand offset partially by increases in net occupancy and equipment expenses of $172 thousand and other expenses of $585 thousand. The improvement in salary and benefits expense was primarily a result of implementing initiatives to eliminate staff redundancies and improve efficiencies along with the Company’s branch network repositioning strategy resulting in branch closures. The increase in net occupancy and equipment expense was due to the acceleration of depreciation on disposed equipment. Other expenses increased primarily due to the recognition of a breakage fee on a contractual arrangement. For the year ended December 31, noninterest expense increased to $42,068 thousand in 2019 compared to $38,925 thousand in 2018. The increase was primarily due to $2.2 million in nonrecurring expenses from the execution of an executive separation agreement and $694 thousand of retirement and severance accruals.

BALANCE SHEET REVIEW

Total assets, loans, net, and deposits totaled $1.1 billion, $852.1 million, and $940.5 million at December 31, 2019. For the three months ended December 31, 2019, total assets, loans and deposits decreased $29.8 million, $31.4 million and $29.1 million, respectively. For the year ended December 31, 2019, total assets decreased $57.6 million or 5.1%. Year to date, loans, net, decreased $41.1 million comparing December 31, 2019 and 2018. Business lending, including commercial and commercial real estate loans, decreased $46.0 million while retail lending, including residential mortgages and consumer loans, decreased $17.4 million for the year ended December 31, 2019. For this same period construction lending increased $22.3 million. A delay in the pipeline build within new markets following new office openings and new employee hires, a more robust competitive environment for existing loan relationships and heightened level of loan payoffs caused the overall decline in the loan portfolio. Total investments were $91.2 million at December 31, 2019, compared to $104.7 million at December 31, 2018. Total

deposits decreased $64.1 million in 2019, as the reduction in loan volumes decreased the need to aggressively price deposits. Noninterest-bearing deposits decreased $15.2 million, while interest-bearing deposits decreased $48.9 million. As a percentage of total deposits, noninterest-bearing deposits amounted to 15.7% at December 31, 2019 and 16.2% at December 31, 2018.

Stockholders’ equity totaled $118.1 million, or $12.81 per share, at December 31, 2019, $117.3 million, or $12.77 per share, at September 30, 2019, and $113.9 million, or $12.49 per share, at December 31, 2018. The increase in equity in the year ended December 31, 2019 was due primarily to a change of $2.3 million in accumulated other comprehensive income and net income of $4.3 million offset partially by dividends declared of $3.2 million. Tangible stockholders’ equity per common share increased to $9.83 at December 31, 2019, compared to $9.75 at September 30, 2019 and $9.39 at December 31, 2018. Dividends declared for the fourth quarter of 2019 amounted to $0.075 per share representing a dividend payout ratio of 2.4% based on the Company’s closing market price on December 31, 2019.

ASSET QUALITY REVIEW

Nonperforming assets were $5.1 million, or 0.60% of loans, net, and foreclosed assets at December 31, 2019 compared to $7.2 million or 0.81% at December 31, 2018. Adjusting for accruing restructured loans, nonperforming assets were $2.4 million, or 0.28% of loans, net and foreclosed assets at December 31, 2019, and $4.3 million, or 0.48%, at December 31, 2018. The allowance for loan losses equaled $7.5 million, or 0.88%, of loans, net, at December 31, 2019, compared to $6.4 million, or 0.71%, at December 31, 2018. Adding accounting marks for purchased credit impaired loans to the allowance for loan losses would result in a ratio of 1.01% as a percentage of loans, net at December 31, 2019. The coverage ratio, allowance for loan losses as a percentage of nonperforming assets, was 148.0% at December 31, 2019 versus 88.1% at December 31, 2018. Excluding accruing restructured loans, the coverage ratio would be 311.4% at December 31, 2019. Loans charged-off, net of recoveries, for the year ended December 31, 2019, equaled $1,238 thousand, compared to $573 thousand for the same period last year.

Safe Harbor Forward-Looking Statements:

We make statements in this press release, and we may from time to time make other statements regarding our outlook or expectations for future financial or operating results and/or other matters regarding or affecting Riverview Financial Corporation, Riverview Bank, and its subsidiaries (collectively, “Riverview”) that may be considered “forward-looking statements” as defined in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements may be identified by the use of such words as “believe,” “expect,” “anticipate,” “should,” “planned,” “estimated,” “intend” and “potential.” For these statements, Riverview claims the protection of the statutory safe harbors for forward-looking statements.

Riverview cautions you that a number of important factors could cause actual results to differ materially from those currently anticipated in any forward-looking statement. Such factors include, but are not limited to: prevailing economic and political conditions, particularly in our market area; credit risk associated with our lending activities; changes in interest rates, loan demand, real estate values and competition; changes in accounting principles, policies, and guidelines; changes in any applicable law, rule, regulation or practice with respect to tax or legal issues; and other economic, competitive, governmental, regulatory and technological factors affecting Riverview’s operations, pricing, products and services and other factors that may be described in Riverview’s Annual Reports on Form 10-K and Quarterly Reports on Form 10-Q as filed with the Securities and Exchange Commission from time to time.

In addition to these risks, acquisitions and business combinations present risks other than those presented by the nature of the business acquired. Acquisitions and business combinations may be substantially more expensive to complete than originally anticipated, and the anticipated benefits may be significantly harder-or take longer-to achieve than expected. As a regulated financial institution, our pursuit of attractive acquisition and business combination opportunities could be negatively impacted by regulatory delays or other regulatory issues. Regulatory and/or legal issues related to the pre-acquisition operations of an acquired or combined business may cause reputational harm to Riverview following the acquisition or combination, and integration of the acquired or combined business with ours may result in additional future costs arising as a result of those issues.

The forward-looking statements are made as of the date of this release, and, except as may be required by applicable law or regulation, Riverview assumes no obligation to update the forward-looking statements or to update the reasons why actual results could differ from those projected in the forward-looking statements.

In addition to evaluating its results of operations in accordance with accounting principles generally accepted in the United States of America (“GAAP”), Riverview routinely presents and supplements its evaluation with an analysis of certain non-GAAP financial measures, such as tangible stockholders’ equity and Core net income ratios. The reported results for the three and twelve months ended December 31, 2019 and 2018, contain items which Riverview considers non-core, namely net gains on sales of investment securities available-for-sale, acquisition related expenses and the adjustment to tax expense due to the enactment of the Tax Act. Riverview presents the non-GAAP financial measures because it believes that these measures provide useful and comparative information to assess trends in Riverview’s results of operation. Presentation of these non-GAAP financial measures is consistent with how Riverview evaluates its performance internally and these non-GAAP financial measures are frequently used by securities analysts, investors and other interested parties in evaluation of companies in Riverview’s industry. Where non-GAAP measures are used in this press release, reconciliations to the comparable GAAP measures are provided in the accompanying tables. The non-GAAP financial measures Riverview uses may differ from similarly titled non-GAAP financial measures of other financial institutions. These non-GAAP financial measures would not be considered a substitute for GAAP basis measures, and Riverview strongly encourages a review of its condensed consolidated financial statements in their entirety. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP measures are presented in the tabular material that follows.
